Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. application Ser. No. 16/959,299 filed Jun. 30, 2020, which claims priority to Korean Patent Application No. 10-2017-0185003 filed with the Korean Intellectual Property Office on Dec. 30, 2017, the disclosures of which are incorporated herein by reference in their entirety.

BACKGROUND

Conventionally, papers of various kinds (corrugated cardboard, cardboard, etc.) are manufactured into a planar sheet of packaging box which is then folded into a three-dimensional packaging box in sequence. After a product is put in the three-dimensional packaging box, the box is sealed at the top and bottom by machine or a simple jig using a steel fixing pin such as a stapler pin and shipped. To unpack the shipped packaging box, at least 12 pins need to be removed from the top and bottom of the box. However, it is inconvenient to remove the stapler pins. Moreover, because the pins are sharp, hand may be injured and the surface of the packaging box may be damaged during the removal of the pins, making it impossible to reuse the box. While the top and bottom of the box may be sealed by an adhesive, this could also damage the packaging box as the surface of the packaging box may be torn off during the unpacking of the box.

As shown in FIG. 1, a packaging box (10) generally has a first cover (11) and a second cover (12) on an upper surface or a lower surface, the first and second covers facing each other to form an inlet. Once product is received through the inlet, the first cover (11) and the second cover (12) of the packaging box (10) are folded together at the inlet to seal the box. The inlet is sealed with a tape (20, see FIG. 2) along edges (111, 112) to sealingly pack the box. However, as shown in FIG. 3, when a tape (21) is applied along edges (111, 112) of the first cover (11) and the second cover (12), the edges (111, 112) may be detached to prevent a complete sealing of the box. To solve this problem, most users would wind the tape (21) around the box while pressing down the edges (111, 112) of the first cover (11) and the second cover (12) with a foot or hand.

Korean Utility Model Publication No. 20-0393769 (hereafter, referred to as “Prior Art Document 1”) discloses a device for folding a packaging box manufactured from papers of various kinds (corrugated cardboard, cardboard, etc.) to be provided in the form of a planar sheet which is then folded into a three-dimensional packaging box in sequence. Korean Patent Publication No. 10-0564806 (hereinafter, referred to as “Prior Art Document 2”) discloses a tape attaching device. According to Prior Art Documents 1 and 2, a packaging box provided in the form of a planar sheet is folded into a three-dimensional packaging box in sequence. After an item is put in the three-dimensional packaging box, the box is taped using the tape attaching device.

However, it is not economically feasible to purchase and store such expensive machine as disclosed in Prior Art Documents 1 and 2, unless it is necessary to handle a large number of packaging boxes at home, post offices, and general offices, etc.

DETAILED DESCRIPTION

Hereinafter, the aforesaid and additional aspects of the present disclosure will be described in detail in exemplary embodiments with reference to the accompanied drawings to enable one of ordinary skill in the art to readily carry it out.

In the present disclosure, the material of a packaging box includes paper (corrugated cardboard, cardboard, etc.), plastic or boards. A packaging box provided in the form of a planar sheet is folded into a three-dimensional packaging box in sequence, so as to allow a product to be placed in the three-dimensional packaging box.

A box holder is a device for pressing an upper surface and respective side surfaces of a polyhedral packaging box towards the central portion of the box. A box holder may include rubber or synthetic resins having good elasticity, or commonly known metals. If a box holder is made of an elastic material, the box holder may be provided to be smaller than a standard size of a packaging box. The packaging box (polyhedron) has respective side surfaces that are pressed towards the central portion thereof, while an upper surface of the box is pressed down (central portion).

If a box holder is made of a heavy material such as a metal, the pressing force of legs of the box holder is imparted to allow respective side surfaces of the packaging box to face toward the central portion of the box, while an upper surface of the packaging box is pressed down by the self-weight of the box holder.

Referring to FIG. 4, a box holder (40) according to a first exemplary embodiment of the present disclosure includes two horizontal bars (41, 42) spaced apart from each other at a predetermined interval; first bent portions (411, 412, 421, 422) bendingly extending from the horizontal bars (41, 42); and first support members (43, 44) to connect the first bent portions (411, 412, 421, 422). The box holder (40) according to a first exemplary embodiment of the present disclosure includes joint portions (45, 46, 48, 49) engaged with the two horizontal bars (41, 42); second bent portions (451, 461, 481, 491) bendingly extending from the joint portions (45, 46, 48, 49); and second support members (47, 50) to connect the second bent portions (451, 461, 481, 491).

According to the first exemplary embodiment of the present disclosure, the horizontal bar (41) may be integrally provided with the bent portions (411, 412) at opposite ends of the horizontal bar (41). The horizontal bar (42) may be integrally provided with the bent portions (421, 422) at opposite ends of the horizontal bar (42). The joint portions (45, 46, 48, 49) may be integrally provided with the second bent portions (451, 461, 481, 491), while one end of each of the joint portions may be coupled to the horizontal bars (41, 42) by welding, etc.

A set of the horizontal bar (41) and the bent portions (411, 412) at the opposite ends thereof provides a transverse bent member. A set of the joint portion (45) and the second bent portion (451) provides a longitudinal bent member. The first exemplary embodiment of the present disclosure includes two transverse bent members disposed parallel to each other; a pair of longitudinal bent members vertically coupled to the transverse bent members to extend therefrom in opposite directions, respectively; and a support member to connect ends of a pair of adjacent bent members.

The plurality of support members (1717, 1718, 1722, 1725) have a width greater than a width of the plurality of support members (1417, 1418, 1422, 1425) of the box holder (1710) according to the fourth exemplary embodiment of the present disclosure.

The fifth exemplary embodiment of the present disclosure includes a pair of symmetrical bars (1711, 1714) comprised of two horizontal bars spaced apart from each other at a predetermined interval and a pair of vertical bars extending vertically from the horizontal bars, respectively, to provide an overall cross shape when disposed in a symmetrical manner; a bent member engageable with respective ends of each of the symmetrical bars (1711, 1714); and a support member to connect each one end of a pair of adjacent bent portions, wherein the support member has a width greater than a width of the symmetrical bar or the bent member so as to increase a supporting force.

Referring to FIG. 18, a user folds a first cover (11) and a second cover (12) to face each other at an inlet of a packaging box (10), and slowly fits the box holder (1710) according to the fifth exemplary embodiment of the present disclosure onto a top surface of the packaging box (10). As the box holder (1710) presses the packaging box (10) to allow respective side surfaces (13) of the packaging box (10) to face toward a central portion of the packaging box (10), the box holder (1410) presses down the first cover (11) and the second cover (12) by the self-weight of the box holder (1410), thereby providing a complete sealing of the packaging box. The box holder holds the covers of the box in place so that the user does not need to hold or push the box with hands when packing, thereby freeing the hands. The user may have the packaging box (10) assembled by the box holder (1710) according to the fifth exemplary embodiment of the present disclosure delivered to a desired location via a courier.

Referring to FIG. 19, the user may attach auxiliary fixing means, for example, a tape (20), along an edge of the box at which the first cover (11) and the second cover (12) of the packaging box (10) are joined together. Although not shown in the drawings, the user may dissemble the box holder (1710) from the packaging box (10) with the tape (21) attached thereto as auxiliary fixing means and have the packaging box (10) delivered to a desired location via a courier.

Referring to FIG. 20, according to a sixth exemplary embodiment of the present disclosure, a box holder (2010) includes a pair of symmetrical bars (2011, 2014) comprised of two horizontal bars spaced apart from each other at a predetermined interval and a pair of vertical bars extending vertically from the horizontal bars, respectively, to provide an overall cross shape when disposed in a symmetrical manner; joint portions (2012, 2013, 2015, 2016, 2019, 2021, 2023, 2024) engaged with respective ends of each of the symmetrical bars (2011, 2014) via a joint screw (14); bent portions (20121, 20131, 20151, 20161, 20191, 20211, 20231, 20241) bendingly extending from the joint portions (2012, 2013, 2015, 2016, 2019, 2021, 2023, 2024); and a plurality of support members (2017, 2018, 2022, 2025) to connect a pair of adjacent bent portions (20121, 20131, 20151, 20161, 20191, 20211, 20231, 20241).

In the box holder (2010) according to the sixth exemplary embodiment of the present disclosure, the joint portions (2012, 2013, 2015, 2016, 2019, 2021, 2023, 2024) have a scale mark so that a user may vary the size of the box holder (2010) to correspond to the size of packaging boxes (31, 32, 33), as shown in FIGS. 21 and 22.

The sixth exemplary embodiment of the present disclosure includes a pair of symmetrical bars (2011, 2014) comprised of two horizontal bars spaced apart from each other at a predetermined interval and a pair of vertical bars extending vertically from the horizontal bars, respectively, to provide an overall cross shape when disposed in a symmetrical manner; a bent member engageable with respective ends of each of the symmetrical bars (2011, 2014); and a support member to connect each one end of a pair of adjacent bent portions. While the sixth exemplary embodiment of the present disclosure is identical to the fourth and fifth exemplary embodiments of the present disclosure, the size of the box holder varies depending on the engagement depth between the bent members and the symmetrical bar, the sixth exemplary embodiment is different in that the user may readily read the degree of variation in the depth based on the scale mark indicated in the bent member. Alternatively, one of ordinary skill in the art may indicate a scale mark on the symmetrical bar.

Referring to FIG. 23, according to a seventh exemplary embodiment of the present disclosure, a box holder (2310) includes two horizontal bars (2311, 2312) spaced apart from each other at a predetermined interval; joint portions (23111, 23112, 23121, 23122) extending from the horizontal bars (2311, 2312); and a support member (2313) to connect the joint portions (23111, 23112, 23121, 23122). The joint portion may be provided as a portion of the horizontal bar.

According to the seventh exemplary embodiment of the present disclosure, the box holder (2310) may include an elastic material, for example, rubber or resins. The box holder (2310) may have a size smaller than a standard size of a packaging box.

Referring to FIG. 24, a user folds a first cover (11) and a second cover (12) to face each other at an inlet of a packaging box (10), and slowly fits the box holder (2310) according to the seventh exemplary embodiment of the present disclosure onto a top surface of the packaging box (10). As the box holder (2310) presses the packaging box (10) to allow respective side surfaces (13) of the packaging box (10) to face toward a central portion of the packaging box (10), the box holder (2310) presses down the first cover (11) and the second cover (12) and the horizontal bars (2311, 2312, see FIG. 23) press the first cover (11) and the second cover (12) by the squeezing force of the support member (2313, see FIG. 23), thereby providing a complete sealing of the packaging box. The box holder holds the covers of the box in place so that the user does not need to hold or push the box with hands when packing, thereby freeing the hands. The user may have the packaging box (10) assembled by the box holder (2310) according to the seventh exemplary embodiment of the present disclosure delivered to a desired location via a courier.

The seventh exemplary embodiment of the present disclosure includes two horizontal bars (2311, 2312) spaced apart from each other at a predetermined interval; and a rectangular support member to connect ends of the respective horizontal bars (2311, 2312) to one another. Each of the horizontal bars (2311, 2312) has a length greater than a length of a side of the rectangular support member that is disposed parallel to the respective horizontal bars.

The user may attach auxiliary fixing means, for example, a tape (21), along an edge of the box at which the first cover (11) and the second cover (12) of the packaging box (10) are joined together. Although not shown in the drawings, the user may dissemble the box holder (2310) from the packaging box (10) with the tape (21) attached thereto as auxiliary fixing means and have the packaging box delivered to a desired location via a courier.

FIG. 25 is an enlarged lateral view of an end (23112) of an exemplary support member applicable to the box holders (40, 80, 1110, 1410, 1710) illustrated in FIGS. 4, 8, 11, 14 and 17, respectively. The end (23112) may have a curved shape or a cut shape (P) so as to allow a lower surface of the packaging box not to contact a side surface of the packaging box, thereby facilitating the fitting of the box holder.

FIGS. 26 to 33 are diagrams for explaining the eighth embodiment of the present invention.

FIG. 26 shows how pressures should be applied to pack a cardboard box.

To pack a cardboard box (10), pressure should be applied on each of the four sides and the top. The arrows indicate the directions of the pressure applied.

FIG. 27 illustrates a fixed type box holder placed on a standard cardboard box.

For example, various kinds of standard boxes are available in-store at the FedEx® office, such as 8″×8″×8″ box, 12″×9″×6″ box, 13″×9″×11″ box, etc. The box holder needs to be designed to have a corresponding dimension to hold the top and side surfaces of a given-sized box.

As illustrated in FIG. 27, when the box holder (500) is placed on a cardboard box (10), it applies pressure to the four sides of the box (10), pushing them towards the center and maintaining stability through its own weight.

FIG. 28 illustrates how to use a duct tape (20) with the fixed type box holder (500).

After the box holder (500) is in place on the cardboard box (10), duct tape (20) is applied to securely fasten the upper flaps of the cardboard box (10). This ensures the box is sealed tightly and ready for shipping.

FIG. 29A illustrates the forces applied when the user lifts the box holder from the box.

FIG. 29B illustrates the forces applied when the user places the box holder onto the box.

FIG. 30A shows the bending of the crossbars of the box holder due to external forces applied during lifting (as shown in FIG. 29A). The external forces cause the crossbars to experience bending moments.

FIG. 30B illustrates the forces applied to the crossbars of the box holder when the holder is placed onto the box (as shown in FIG. 29B). The lowering force creates compressive stresses in the crossbars, potentially causing them to bend.

FIG. 31 illustrates an improved box holder designed to address the issues depicted in FIGS. 30A and 30B, where the crossbars of the T-frame are prone to bending under external forces. The improvement involves the addition of ribs to the crossbars of the T-frame, enhancing the structural integrity and rigidity of the box holder.

The improved box holder (500) includes a pair of T-frames (510, 520) arranged parallel to face opposite directions. The three edges of each T-frame (510, 520) are bent downward at a 90-degrees angle to form vertical brackets (532, 542). These vertical brackets (532, 542) provide additional support and pressure to the sides of the box (10), ensuring it remains stable and does not deform.

The vertical brackets (532, 542) are formed by bending the edges of the T-frames (510, 520) downward. The length brackets (532) are located at the ends of the crossbars of the T-frames (510, 520), while the width brackets (542) are located at the ends of the stems of the T-frames (510, 520). The vertical brackets (532, 542) are integrally formed as a part of the T-frames (510, 520). The first angle (01) at a first edge (533, 543), i.e., between T-frame (510, 520) and the vertical bracket (532, 542), is preferably 90 degrees.

Each end of vertical brackets (532, 542) is integrally extended to form bar-shaped extension (534, 544). The extension (534, 544) is slightly bent outwardly at a second edge (535, 545) between the vertical racket (532, 542) and the extension (534, 544). The second angle (02) at the second edge (535, 545) is designed to be obtuse, creating a space between the inner surface of the extension (534, 544) and the outer surface of the box (10), allowing the box holder (500) to be easily or smoothly placed on and removed from the box (10) and enabling the box holders (500) to be stacked on top of each other.

A handle (536) is formed at the end of the bar-shaped extension (534). The third edge (537) between the bar-shaped extension (534) and the handle (536) forms a third angle (03) that is obtuse. The third obtuse angle (03) at the third edge (537) is usually set to be smaller than the second obtuse angle (02) and larger than the first right angle (01). Preferably, the third angle (03) makes the handle (536) parallel to the ground to facilitate easy lifting and maneuvering. The handle (536) ensures efficient transfer of forces from the user's grip through the structure.

The open edge of the T-frame (510) faces the open edge of the other T-frame (520). Each open edge of the T-frame (510, 520) extends upward to form a rib (550, 560). The rib (550, 560) is vertically formed along the open edges of crossbars of the T-frames (510, 520) arranged in horizontal directions. The ribs (550, 560) provide pressure-resistant support to the crossbars of the T-frames (510, 520) when external forces are applied by lifting or pushing down the box holder (500). The ribs (550, 560) are strategically positioned along the crossbars to distribute and resist both bending and compressive forces, addressing the deformation issues seen in FIGS. 30A and 30B. The cross bars of the T-frames (510, 520) may be used as advertising spaces by printing advertising text and/or images (530) on them.

The addition of ribs (550, 560) in the improved box holder (500) significantly increases the rigidity of the crossbars, preventing them from bending under lifting (FIG. 30A) and lowering (FIG. 30B) forces. The ribs (550, 560) provide continuous support along the length of the crossbars, ensuring the box holder (500) maintains its structural integrity even under heavy loads. The ribs (550, 560) help distribute the forces more evenly across the structure, reducing stress concentrations and potential points of failure.

FIGS. 32A and 32B illustrate the bending and deformation of the handle and the extension part of the box holder due to external forces. These FIGS. show that the lack of ribs in these areas leads to deformation when a force is applied. The grey arrows indicate the direction of the external force, while the white arrows highlight the areas where bending and deformation occur.

FIG. 33 represents another improved box holder with additional reinforcement elements added to the box holder shown in FIG. 31.

In this design, the bar-shaped extensions are connected to form a single U-shaped extension (538). The U-shaped extension (538) provides a more continuous and robust reinforcement compared to the separate bar-shaped extensions (534) in FIG. 31. The connected U-shaped extension (538) helps distribute forces more evenly across the structure, reducing the risk of deformation. The improved box holder (500) in FIG. 33 benefits from both the ribs (550, 560) and the U-shaped extension (538), resulting in a more robust and stable box holder compared to the design in FIG. 31.

By comparing the two figures, it is clear that the U-shaped extension (538) in FIG. 33 provides superior reinforcement and stability compared to the separate bar-shaped extensions (534) in FIG. 31. This improvement addresses potential weaknesses in the earlier design, ensuring the box holder can withstand greater external forces without compromising its structural integrity.

FIG. 34 illustrates the progressive enhancement of resistance to external forces and structural rigidity from the first to fourth designs. The diagrams show how adding and improving structural elements can significantly increase the box holder's ability to withstand external forces without deforming.

The first design, named the Basic Flat Plate, features the fundamental structure without any additional reinforcement. This design has minimal resistance to external forces, as there are no reinforcing elements to support the structure, resulting in the lowest rigidity, making it prone to bending and deformation under external forces.

In the second design, named the Single-Sided Rib Reinforced Plate, ribs are incorporated on one side of the flat plate. This modification improves resistance compared to the Basic Flat Plate. The added ribs provide extra support, helping the structure withstand some external forces. Consequently, the rigidity of the plate is increased, reducing the likelihood of bending. However, the support remains limited compared to more advanced designs.

The third design, known as the Double-Sided Rib Reinforced Plate, features ribs added to both sides of the flat plate. This design shows further improvement in resistance, as reinforcing both sides allows the structure to better resist external forces from multiple directions. The rigidity is significantly enhanced, with the dual-sided ribs creating a more robust framework, thus minimizing deformation under load.

The fourth and final design, called the Box Beam, showcases an integrally formed rib structure. This design provides the maximum resistance to external forces among the four designs. The integrally formed ribs offer continuous support, ensuring the structure remains stable under high stress. The rigidity is at its highest in this design, with the integrated ribs forming a unified, strong structure that distributes forces evenly, virtually eliminating the risk of bending or deformation.

As the designs progress from the Basic Flat Plate to the Box Beam, there is a marked increase in resistance to external forces and rigidity. Each subsequent design builds on the previous one, adding and optimizing ribs to transform the basic flat plate into a highly rigid and stable structure capable of withstanding greater external forces. The Box Beam represents the optimal solution for maximizing strength and stability. While the Basic Flat Plate and Single-Sided Rib Reinforced Plate are simpler and easier to manufacture, the Double-Sided Rib Reinforced Plate and Box Beam involve more complex manufacturing processes due to the additional ribs and integrally formed structures. However, the trade-off is justified by the significant improvements in resistance and rigidity, making the Box Beam the most robust design among the four.

The eighth embodiments shown in FIGS. 31 and 33 apply the second design, known as the Single-Sided Rib Reinforced Plate, whereas the ninth embodiment shown in FIGS. 35 to 37 applies the fourth design, known as the Box Beam.

FIG. 35 illustrates an adjustable typed box holder according to the ninth exemplary embodiment of the present invention.

The adjustable type box holder (600) includes a pair of hollow T-frames (610, 620) arranged parallel to face opposite directions. These hollow T-frames (610, 620) utilize the Box Beam structure illustrated in FIG. 34, which provides enhanced rigidity and strength. The hollow T-frame may be made by the integration of rib plates or double sided rib plate along the crossbar. The three edges of each hollow T-frame (610, 620) form open ends. A hole (not shown) for receiving knob (650) is formed on the upper surface near each edge of the hollow T-frame (610, 620). The knob (650) is used for fixing the adjustable horizontal and vertical arms (630, 640) in a predetermined position corresponding to the length and width of the box, respectively. The user may fit the box holder (600) to any box with various dimensions by inserting the adjustable arms (630, 640) into the respective fixing position.

A slidable horizontal arm (630) includes a pair of horizontally parallel bars. The bars may or may not be hollow. They can employ the third design (i.e., the Double-Sided Rib Reinforced Plate) or the fourth design (i.e., the Box Beam) in FIG. 34. The outer edge of each horizontal bar is bent 90 degrees downward to form a vertical length bracket (632). Each end of vertical length brackets (632) is integrally extended to form a U-shaped extension (634). The edge between the vertical length bracket (632) and the U-shaped extension (634) makes an obtuse angle. This obtuse angle allows a slight gap between the outer surface of the box (10) and the inner surface of the U-shaped extension (634) to prevent the box holder (600) from getting stuck in the box (10) and also enables the box holders (600) to be stacked on top of each other.

The open end of the U-shaped extension (634) is further extended to form a handle (636). The edge between the U-shaped extension (634) and the handle (636) also forms an obtuse angle. The obtuse angle may be set to make the handle (636) parallel to the ground.

A slidable vertical arm (640) includes an elongated bar, of which the outer edge is bent 90 degrees downward to form a vertical width bracket (642). The end of the vertical width bracket (642) is integrally extended to form a I-shaped extension (644). The edge between the vertical width bracket (642) and the I-shaped extension (644) makes an obtuse angle. A secondary handle could be integrally formed by the extension of the I-shaped extension (644) from its open end. FIG. 36 illustrates another adjustable typed box holder with telescopic structure.

Compared to the box holder in FIG. 35, the box holder (600) in FIG. 36 includes additional features, specifically at least one set of hollow extension frames (660, 680) that form a telescopic structure. These hollow extension frames (660, 680) are slidably inserted between each open ends of the hollow T-frame (610, 620) and inner edges of the adjustable arms (630, 640). Additional hollow extension frame (not shown) can also be inserted into the telescopic structure, creating a multi-stage telescopic mechanism for allowing the box holder (600) to accommodate larger boxes.

The coupling mechanism between the hollow frames (610, 620, 630, 680) and the adjustable arms (630, 640) can take various forms, as long as it supports the overall telescopic structure of the adjustable type box holder (600). For example, other types of coupling mechanism, such as telescopic cylinders, could also be used.

FIG. 37 illustrates another adjustable typed box holder (600) with telescopic structure and an additional feature for displaying advertisements.

The advertisements can be in the form of printed graphics, stickers, or digital displays, depending on the specific design and use case. This feature allows business to utilize the box holder not only as a functional tool for transporting and holding boxes but also as a medium for advertising and brand promotion. The addition of advertising spaces on the crossbars makes the box holder in FIG. 37 particularly useful for retail environments, trade shows, and promotional events where visibility and brand messaging are important.

FIG. 38, FIG. 39A, and FIG. 39B illustrate the tenth exemplary embodiment of the present invention.

This embodiment features an advanced box holder design incorporating ribs (750, 760) on the crossbars and the U-shaped extensions, enhancing both structural integrity and resistance to external forces.

In FIG. 38, the box holder (700) includes a set of T-frames (710, 720) arranged parallel to each other. The key feature of this design is the continuous loop of ribs (750, 760, 770) extending from the crossbars of the T-frames (710, 720) to the U-shaped extensions (738). The enhanced rigidity due to the formation of the continuous loop of ribs (750, 760, 770) ensures that the box holder (700) maintains its shape and stability even under heavy loads. The ribs not only provide vertical support but also connect the inner edges of the T-frames (710, 720) and the U-shaped extension (738), distributing the load more evenly and reducing stress points. This design ensures that the pressure is supported across a larger area, including the extensions (738), which enhances the overall stability and rigidity of the box holder. The more integrated design reduces the likelihood of deformation at connection points, making the structure more resistant to bending and external forces.

Additionally, FIG. 39A and FIG. 39B show modifications to the box holder in FIG. 38, where the third edge (737) where two faces (736, 738) meet at an obtuse angle is beveled with two or more notches. Across these notches, braces (780) are installed. FIG. 39A provides an isometric view, while FIG. 39B show a cross-sectional view of these modifications. These braces (780) are designed to enhance the support, rigidity, and resistance of the handle area by reinforcing the edge parts. By reinforcing the beveled edge with these braces, the overall structural integrity of the box holder is further improved, providing additional strength and stability.

Overall, the addition of ribs that extend from the crossbars into the U-shaped extensions represents a major advancement in the design of the box holder. This feature makes the box holder in the tenth embodiment far more resilient and reliable, suitable for a wide range of demanding applications.

FIG. 40A and its cross-sectional view FIG. 40B, along with FIG. 41A, FIG. 41B, FIG. 42A, FIG. 42B, FIG. 43A and FIG. 43B, illustrate an eleventh exemplary embodiment of the present invention, showcasing various modifications of the box holder design. FIG. 40B is a cross-sectional view along line AA′ and BB′ in FIG. 40A. FIG. 41B is a cross-sectional view along line AA′ and BB′ in FIG. 41A. FIG. 42B is a cross-sectional view along line CC′ in FIG. 42A. FIG. 43B is a cross sectional view along line CC′ in FIG. 43A.

In this embodiment, a pair of reinforcement plates (850, 852, 854, 856; 860, 862, 864, 866) are attached to the crossbars of the T-frame (810, 820), vertical brackets (832) and the U-shaped extensions (838).

Each reinforcement plate (850, 860) is designed as a continuous, integral component. This continuous design ensures that the reinforcement plates (850, 860) effectively distribute applied forces across the entire structure, significantly reducing stress concentrations and minimizing the risk of deformation, thus enhancing the rigidity and stability of the box holder (800).

The key difference between the embodiments shown in FIG. 40A, 40B and FIG. 41A, 41B lies in the nature of the reinforcement elements. The solid reinforcement plates in FIGS. 40A and 40B offer robust support and are ideal for applications where maximum strength and durability are required. In contrast, the hollow reinforcement strips in FIGS. 41A and 41B provide a lighter alternative that still maintains significant rigidity, making them suitable for situations where weight is a critical factor.

The key difference between the embodiments shown in FIG. 40A, 40B and FIG. 42A, 42B is the shape of the reinforcement elements. The reinforcement plates (854, 864) in FIGS. 42A and 42B extends not only along the crossbars of the T-frame (810, 820) but also along the stems to form a T-shaped reinforcement plates facing against each other. This T-shaped reinforcement plates (854, 864) provide superior structural support and rigidity.

The key difference between the embodiments shown in FIG. 42A, 42B and FIG. 43A, 43B lies in the nature of the reinforcement elements. The box holder (800) in FIGS. 43A and 43B includes a hollow T-shaped reinforcement strip (856, 866), while the box holder (800) in FIGS. 42A and 42B has a solid T-shaped reinforcement strips (854, 864).

Comparing these to the earlier embodiments, FIG. 40A, 40B feature solid reinforcement plates, while FIG. 41A, 41B have hollow reinforcement strips. The T-shaped reinforcement strips in FIG. 42A, 42B and FIG. 43A, 43B, whether solid or hollow, offer improved structural support due to their extended configuration, distributing forces more effectively than the simpler designs in the earlier figures.

FIG. 44A and its cross-sectional views FIG. 44B, and FIG. 44C illustrate a twelfth exemplary embodiment of the present invention. This embodiment adopts the third design structure in FIG. 34, known as the Double-Sided Rib Reinforced Plate, to enhance the strength and rigidity of the box holder.

In this embodiment, the box holder (900) includes T-frames (910, 920) with crossbars and stems, vertical brackets (932, 942) and U-shaped and I-shaped extensions (938, 944) as well as handles (936), all of which are reinforced with double-sided ribs. These double-sided ribs provide superior structural support and significantly enhance the rigidity of the box holder.

FIG. 44B is a cross-sectional view along line AA′ and BB′ in FIG. 44A. FIG. 44C is a cross-sectional view along line CC′, showing the double-sided rib structure.

By utilizing the Double-Sided Rib Reinforced Plate structure from FIG. 34's third design, the box holder (900) in this embodiment benefits from increased rigidity and resistance to external forces. The double-sided ribs formed along all edges of the box holder (900) ensure that the box holder (900) maintains its shape and stability even under heavy loads, making it suitable for a wide range of demanding applications. Here, pads (990) are added to the handles (936) to enhance user comfort by facilitating easier gripping and preventing finger discomfort.

The box holder of the present invention is placed over the top of a packaging box where its bent portions and support members press the box's sides towards the center, and the horizontal crossbars apply downward pressure on the box's covers. This configuration holds the box firmly, allowing for easy application of sealing tape without needing additional hands to keep the box closed.

The box holder frees the user's hands during the packing process, making it convenient and safe. It is designed to be easy to disassemble from the box once the tape is applied, ensuring that the packing process is efficient and the box remains undamaged.

The design of the box holder allows it to be adjustable or fixed, catering to different box sizes and shapes. It can be scaled in size by modifying the length of the horizontal bars and support members, making it adaptable to various packaging requirements.

Some versions of the box holder might include features such as scale marks for precise fitting and potentially a tape cutter attached to the holder, enhancing its utility and user-friendliness.

This detailed structure ensures that the box holder is a practical tool for securely sealing and packing boxes, minimizing the risk of damage and increasing efficiency in packing operations.

Aforementioned box holders may utilize various materials including metals such as steel, aluminum, and stainless steel, as well as non-ferrous metals like copper, zinc, lead, nickel, tin, and various alloys. Plastics like PETE, HDPE, PVC, LDPE, PP, PS, HIPS, and ABS can also be used.

The aforementioned box holders may be fabricated through various manufacturing processes including Bending, Die Casting, Pressing, and Injection Molding.

Although exemplary embodiments of the present disclosure have been shown and described with reference to the accompanied drawings to enable one of ordinary skill in the art to readily understand and reproduce the present disclosure, the present disclosure is not limited to the described embodiments. Instead, it would be appreciated by one of ordinary skill in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
