Hermetically sealed container
A container for containing articles is disclosed. The container comprises a first section and a second section. The first section is capable of engaging the second section to form a hermetic seal. The first section has a first cavity that is surrounded by a first peripheral wall and a peripheral edge. The first peripheral wall has a first surface that is angled toward the peripheral edge. The second section has a second peripheral wall that is capable of sliding between the first peripheral wall and the edge to form a hermetic seal.
The present disclosure relates to a sealed container. More particularly, the present disclosure relates to a hermetically sealed container, such as a hermetic cosmetic compact container.
BACKGROUNDVarious sealed containers or cases exist for storing and holding different types of contents. Many of these containers are designed for holding contents which are volatile and evaporate or dry quickly when left exposed. Examples of such volatile contents include moistened wipes, cosmetics, water, and/or other solvent based products. In the cosmetic industry, manufacturers are attempting to make a hermetic cosmetic container because the cosmetic contents often contain a volatile chemical component that requires hermetic storage to prevent or inhibit drying, hardening, and cracking of the components.
In general, compact containers hold cosmetics including makeups such as powders, crémes, eye shadows, eyeliners, lip-colors, or other beauty aids. A base section of many compacts often includes a metal pan for containing cosmetics. Alternatively, the cosmetics can be directly stored in a cavity in the base section. Some compacts are arranged as a one-piece unit so that one hand opens and holds the compact, while the other hand applies the cosmetic to the skin surface of the face. For example, some compact containers include a lid or a cover section hingeably coupled to a base or a container section. Either the cover section or the base section can be pivoted about the hinge to obtain the closed configuration of the compact, thereby providing a convenient storage device.
Cosmetic containers may also be in the form of a container with a screw-on cap. With a screw-on cap design, the user must contend with two separate pieces, which can make applying the cosmetic a difficult task. For example, the user must unscrew the cap and place it somewhere so that one hand can hold the container that stores the cosmetic, while the other hand is free to apply the cosmetic to the skin surface of the face. The user has to either hold the cap when applying the cosmetic or lay the screw-on cap somewhere during the process of applying the cosmetic. A separate cap also increases the probability for the cap to be misplaced or lost. Without the screw-on cap, the unused portion of the cosmetic remaining in the container will dry, harden and crack, generally resulting in a product of deteriorated quality. As a result, the user incurs additional expense by having to purchase replacement cosmetic.
Another problem with existing screw-on cosmetic containers is that a user may not be aware that the screw-on cap is not properly closed, e.g., screwed on the container. If the cap is not properly placed on the container, more air flow will be permitted allowing volatiles to escape. This likely results in a low-quality cosmetic that is dried, hardened, and/or cracked.
Another problem with existing cosmetic containers is that some containers require complicated mechanisms to create a hermetic seal. For example, instead of a seal being created substantially between two surfaces, some cosmetic containers utilize the interaction of numerous surfaces and angles to create a hermetic seal. Some containers further require some type of curve or bend along portions of the sealing surfaces to create a “snap-fit” to secure a container in a closed configuration. Accordingly, a significant amount of force is often required to open and close certain cosmetic containers.
Thus, there is a need for an improved container that is inexpensive and simple-to-use while being capable of effecting a hermetic seal. Further, there is a need for an improved hermetically sealed compact container that can be manufactured as a one-piece unit and can be simply opened and closed. Further, there is a need for an improved hermetically sealed container that does not require complicated closing mechanisms involving multiple surfaces or “snap-fits” to lock the container in a closed configuration.
It would be desirable to provide a container having any one or more of these or other advantageous features.
SUMMARYThe present disclosure relates to a cosmetic container. The cosmetic container comprises a first section including a first interface and a second section for holding a cosmetic substance. The second section includes a second interface. One of the first interface and the second interface comprises a groove and the other of the first and second interface comprises a peripheral rim. The groove is defined by a peripheral wall and a peripheral edge, the peripheral wall comprising a first surface angled towards the peripheral edge. The cosmetic container may include an outer body coupled about the first section and second section. The first section and the second section may be integral and joined by a living hinge. Other coupling devices may be used.
The present disclosure further relates to a container for containing articles. The container comprises a first section and a second section. The first section is capable of engaging the second section to form a hermetic seal. The first section has a first cavity that is surrounded by a first peripheral wall and a peripheral edge. The first peripheral wall has a first surface that is angled toward the peripheral edge. The second section has a second peripheral wall capable of sliding between the first peripheral wall and the peripheral edge to form the hermetic seal. The container may include a fist end on the first peripheral wall wherein the first end is angled with respect to the vertical axis. The peripheral wall may be made from a substantially flexible plastic material.
The present disclosure further relates to a method of making a cosmetic container. The method comprises providing a first section including a first interface and providing a second section for holding a cosmetic substance. The second section includes a second interface. The method also comprises providing a groove on one of the first interface and the second interface and providing a peripheral rim on the other of the first interface and the second interface. The groove is defined by a peripheral wall and peripheral edge. The peripheral wall comprises a first surface angled towards the peripheral edge of the peripheral rim. The peripheral wall may be flexible and the first interface and the second interface may be circular.
The present disclosure further relates to a container for cosmetic material comprising a means for containing at least one cosmetic material within a container that may be selectively configured between an open position and a closed position, and a means for providing at least one interface capable of creating a hermetic seal when the container is in the closed position, the interface having an angled surface.
The present disclosure further relates to a container comprising a first section and a second section. The first section is capable of engaging the second section to form a hermetic seal. The first section has a cavity for containing a substance comprising a volatile compound or a product comprising a volatile component contained therein. The cavity is surrounded by a first peripheral wall and a peripheral edge, the first peripheral wall having a first surface that is angled toward the peripheral edge. The second section has a second peripheral wall capable of sliding between the first peripheral wall and the edge to form a hermetic seal. The first and second sections may be integral and joined by a living hinge.

As shown in the embodiment of
With reference to
First section 24 of insert 22 may optionally include a cavity 30 as shown in
In one embodiment, when in the fully extended configuration, insert 22 spans a length of approximately 2-12 inches, having a respective approximate 1-6 inch length for both first section 24 and second section 26. Alternatively, insert 22 can have other dimensions complementary to fit any sized compact 10.
With reference to
Both
In one embodiment, the height of peripheral rim 36 (
Peripheral wall 44 (
Alternatively, other dimensions can be used. For example, this disclosure contemplates various shapes for surface 64 (e.g., curved, rectangular, triangular, etc.). Accordingly, the given dimensions and descriptions are exemplary only and do not limit the scope of the claims.
The closing and opening of insert 22 is discussed as follows. In one embodiment, insert 22 is closed by applying a downward force, such as, by hand, to first section 24 to effect a pivotal motion of first section 24 toward second section 26. More specifically, as a result of the applied downward force on first section 24, hinge 28 folds to close first section 24 onto second section 26.
In the process of closing insert 22, groove 48 receives peripheral rim 36 between peripheral wall 44 and peripheral edge 33 (
The angle of surface 49 toward groove 48 creates an improved hermetic seal. As rim 36 is moved into groove 48, rim 36 first makes contact with free end 45 and chamfer edge 52. The angled shape of free end 45 and the curved shape of chamfer edge 52 direct rim 36 into position for placement within groove 48. As rim 36 continues to push upward against free end 45, wall 44 begins to move outward away from groove 48. The angle of wall 44 helps create biasing force between rim 36 and wall 44 that maintains a hermetic seal.
Once rim 36 is positioned within groove 48, the angle of wall 44 provides enough tension to keep rim 36 in groove 48. Compact 10 may not require a latch to maintain insert 22 in the closed configuration. For example, the angle of peripheral wall 44 holds peripheral rim 36 in place to maintain the seal. As insert 22 obtains the closed configuration, the evacuated air may make a distinctive audible sound, indicating that the hermetic seal has been established.
To open insert 22, a pushing or pulling force is applied, such as, by hand, to first section 24 in a direction away from second section 26. In the process of separating or disengaging first section 24 from second section 26 from the closed configuration of insert 22, peripheral rim 36 is removed from within groove 48, thereby disrupting, e.g., breaking, the hermetic seal formed at the interface between peripheral surface 34 and peripheral wall 44. As first section 24 is disengaged from second section 26, another audible sound may be emitted, indicating the hermetic seal has been broken. As hinge 28 unfolds, first section 24 is further moved in a direction away from second section 26.

In one embodiment, lip 38 may have a width of about 0.02 to 0.1 inches, preferably about 0.045 inches and a height of about 0.02 to 0.1 inches, preferably about 0.05 inches. Lip 38 may also be designed to be spherical with a radius of about 0.005 to 0.1 inches, preferably about 0.01 inches at an end 72. However, the lip 38 is not intended to be limited to such design. For example, a lip 38 may have a variety of other suitable dimensions.
According to an exemplary embodiment, bulge 54 of peripheral edge 33 may be curved with a radius of about 0.005 to 0.03 inches. According to a preferred embodiment, bulge 54 has a radius of approximately 0.01 inches. A wall 62 associated with indent 56 may be provided at an angle in the range of about 10 to 60 degrees from the vertical axis. According to a preferred embodiment, wall 62 is provided at an angle of about 30 degrees from the vertical axis. According to an exemplary embodiment, groove 48 may have a width of about 0.025 to 0.125 inches, preferably about 0.05 inches. According to an exemplary embodiment, bulge 54 may be from about 0.03 to 0.1 inches from a surface 64 and terminates from about 0.06 to 0.25 inches from surface 64. According to a preferred embodiment, bulge 54 is about 0.05 inches from surface 64 of groove 48 and terminates at a distance of about 0.11 inches from surface 64.
Alternatively, other dimensions can be used. For example, this disclosure contemplates various shapes for surface 64 (e.g., curved, rectangular, triangular, etc.). Accordingly, the given dimensions and descriptions are exemplary only and do not limit the scope of the claims.
In the process of closing insert 22, groove 48 receives peripheral rim 36 between peripheral wall 44 and peripheral edge 33 (
Once lip 38 is positioned within groove 48, the angle of wall 44 provides enough tension to keep lip 38 in groove 48. Compact 10 may not require a latch to maintain insert 22 in the closed configuration. As insert 22 obtains the closed configuration, the evacuated air makes a distinctive audible sound, indicating that the hermetic seal has been established.
According to an exemplary embodiment, insert 22 (shown in
Polypropylene is the preferred material for this application. Polypropylene has many advantages including the following: (a) it flows easily during injection and fills thin walls; (b) it forms living hinges capable of withstanding millions of cycles; (c) it is flexible enough to allow deformation during closing of the container; (d) it has a very low water-vapor-transmission-rate (MVTR), which means that weight loss of water and hydrophilic substances through the walls of the container is minimal; (e) it has very good chemical resistance to a wide range of chemicals used in cosmetic formulas; and (f) it is inexpensive. However, according to other embodiments, other types of materials may be used.
External components of the compact (such as the cover and base) are typically also injection molded. Typical thermoplastic materials used for the external components include styrenics (e.g., acrylonitrile butadiene styrene, styrene acrylonitrile, polystyrene, medium impact polystyrene, high impact polystyrene), acrylic (polymethylmethacrylate) or other suitable resins. The main purpose of the external components is to provide stiffness to the assembled compact and provide more esthetically pleasing surfaces than can be achieved with polypropylene.

The advantages of the containers described herein are shown in the following example. A 24-hour water weight loss test was conducted on several known cosmetic containers. To begin the test, the empty test engines were weighed. 10 grams of water was then placed in the inserts (e.g., engines). The inserts were then closed and weighed again. After that, the filled inserts were placed in a humidity-controlled oven at 50 degrees Celsius and 60 percent relative humidity. After 24 hours, the inserts were weighed again. The 24-hour weight loss in percent is calculated as follows: (initial filled weight−filled weight after 24 hours)/(initial filled weight−empty weight)×100%. The results of the test are shown in the following table:
Furthermore, the disclosed cosmetic container showed a decrease in the 24-hour weight loss to about 0.02 to 0.04 percent when left in the oven over the course of about 1-2 weeks.
