This application is a continuation-in-part of U.S. patent application Ser. No. 10/656,027, filed on Sep. 4, 2003, and claims benefit of priority to U.S. Patent Application Ser. No. 61/083,063, filed on Jul. 23, 2008, the entire contents of which are hereby incorporated by reference in the present application.
FIELD OF THE INVENTIONAspects of the present invention relate to closure devices. More particularly, the present invention, in certain aspects, provides an apparatus for sealing bags.
BACKGROUND OF THE INVENTIONMany types of products are offered for sale in hermetically sealed bags to prevent the contamination of the product, and to generally preserve the quality of the product prior to sale. When the bag is opened by a consumer, the product contained therein is exposed to air, which may progressively degrade the quality of the product. For example, where the product is a food product, an opened bag generally exposes the product to microbial agents such as bacteria that accelerate the decay of the product. The food product may also be exposed to atmospheric moisture that may render the food product less appealing. Alternatively, moisture present in the food product may be lost to the atmosphere, so that the food product becomes dehydrated. As a consequence, it is frequently necessary to reseal a bag after opening in order to preserve the food product.
One prior art apparatus for resealing an opened bag is a spring clamp device having a pair of opposed and elongated jaws that clamp the opened end of the bag closed. Known spring clamp devices are generally available only in limited sizes so that the elongated jaws may not extend the entire width of the opened end portion of the bag. As a result, the spring clamp device may fail to adequately seal an opened bag properly. In addition, known spring clamp devices are comprised of numerous parts, and therefore are relatively expensive to manufacture.
Another prior art apparatus for sealing an opened bag is the well-known ZIP-LOC closure. Although the ZIP-LOC closure desirably permits an opened bag to be hermetically resealed, the bag that is supplied to the consumer must be configured with the ZIP-LOC closure. Since many currently-available food products are provided in bags that do not include the ZIP-LOC closure, a consumer is required to transfer the contents from a bag that does not possess the ZIP-LOC closure into a bag that has a ZIP-LOC closure in order to attain the desirable features associated with the ZIP-LOC closure. Since this may require the purchase of additional bags, this approach constitutes an added expense for a consumer. Additionally, ZIP-LOC type closures have a tendency to fail under harsh conditions, such as for example when used on bags containing goods which are to be stored frozen.
Still other bag resealing devices are known in the art. For example, flat closures of the type commonly found on bags containing bread and the like are useful for retaining the bag contents within the bag, but generally only partially hermetically seal the contents of the bag. As a result, flat closures are generally found only on food products having a limited shelf life.
Accordingly, it would be desirable to have a bag sealing apparatus that may be applied to many types of opened bags, and that may be conveniently and rapidly attached to the bag to provide an effective seal that is substantially air-tight under a variety of conditions. It would further be desirable to have a bag resealing device that is relatively inexpensive to manufacture.
SUMMARYAccording to one embodiment, a sealing apparatus is provided. The sealing apparatus includes an elongated sealing portion extending from a first proximal connected end to a distal end. The sealing apparatus also includes an elongated receiver portion extending from a second proximal connected end to a distal opened end. The receiver portion includes a gap extending along a length of the receiver portion, at least one engagement aperture for accommodating the sealing portion therein, and one or more lugs extending generally outwardly therefrom. The sealing apparatus further includes a flexible member. The flexible member joins the sealing portion and the receiver portion at their respective proximal connected ends and operates to allow the sealing portion and the receiver portion to be pivoted relative to one another between a sealed position and a released position.
These and other features and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, wherein it is shown and described illustrative implementations of the invention, including best modes contemplated for carrying out the invention. As it will be realized, the invention is capable of modifications in various obvious aspects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and detailed description are to be regarded as illustrative in nature and not restrictive.
Certain embodiments of the present disclosure provide a sealing apparatus for use in sealing an open end of a bag, pouch, tube, or similar container. The various aspects of the present disclosure are described below with reference to the figures.
In some embodiments, receiver portion 114 may include an elongate member extending from a proximal connected end 115 to a distal opened end 117. The receiver portion 114 includes a centrally-positioned engagement aperture 116 that may extend along substantially the entire length of the receiver portion 114. While engagement aperture 116 is depicted as a circular aperture, engagement aperture may have any shape, such as for example, elliptical or polygonal. As illustrated in
Receiver portion 114 may further include a gap 118 extending along substantially the entire length of the receiver portion 114 on a side of the receiver portion 114 adjacent the sealing portion 112. The gap 118 may define a pair of opposed opening ridges 119 extending along substantially the entire length of the receiver portion 114. Gap 118 may generally maintain a constant width between the ridges 119 along the length of the receiver portion 114. In certain implementations, the constant width between ridges 119 may be less than the widest dimension of the sealing portion 112.
In some implementations, receiver portion 114 may have a non-uniform cross-section. For example, in one embodiment, proximally connected end 115 may have a substantially U-shaped cross section, where one or more lugs begin to extend generally outwardly from the receiver portion at a position spaced distally apart from the proximal connected end, and wherein the distance the lugs extend outwardly from the receiver portion increases in the distal direction. At a position spaced distally apart from the proximal connected end 115, one or more lugs 120 may begin to extend generally outwardly from the receiver portion 114. The distance lugs 120 extend from the receiver portion may increase in the distal direction, such that the lugs 120 extend outwardly from the receiver portion 114 a maximum distance at approximately the distal opened end 117 (i.e., the lugs 120 taper as they extend proximally (
In certain implementations, as illustrated in
Receiver portion 114, at its proximal connected end 115, may be coupled to flexible member 124. In certain implementations, the receiver portion 114 may be integrally formed with flexible member 124. Alternatively, receiver portion 114 may be coupled to the flexible member 124 by any suitable connection means, such as for example, epoxy or heat welding.
The bag sealing apparatus 100 may further include an elongated sealing portion 112 extending from a proximal connected end 126 to a distal end 128. Generally, sealing portion 112 may be sized and shaped such that in the sealed position, substantially the entire sealing portion 112 may be accommodated in the engagement aperture 116 of the receiver portion 114. In this regard, the sealing portion 112 may have a cross-section that is substantially complementary to the shape of engagement aperture 116. For example, sealing portion 112 may have a generally circular, or partially circular cross section, which may be solid or may be at least partially solid, so that the sealing portion 112 is generally tubular. As shown (
In some embodiments, sealing portion 112 may include a gripping member 130, which may be positioned distally adjacent to the distal end 128 of sealing portion 112. Gripping member 130 may be formed integrally with respect to the sealing portion 112, or alternatively, may be coupled to the sealing portion 112 by a number of suitable connection means. Generally, gripping member 130 may assist a user in manipulating the respective portions of the apparatus 100, as will be described in greater detail below.
In certain implementations, a top exterior surface 132 of the gripping member 130 may be shaped generally complementary to a top exterior surface 134 of the receiver portion 114, at least at distal opened end 117, such that in the sealed position, the top exterior surface of the sealing apparatus 100 is a substantially continuous surface (
Sealing portion 112, at its proximal connected end 126, may be coupled to flexible member 124. In certain implementations, the sealing portion 112 may be integrally formed with flexible member 124. Alternatively, sealing portion 112 may be coupled to the flexible member 124 by any suitable connection means.
In some embodiments, flexible member 124 may integrally join receiver portion 114 to sealing portion 112 as well as allow sealing portion 112 and receiver portion 114 to be pivoted relative to one another to accommodate sealing and/or unsealing of a bag. Such an integrally formed structure is advantageous in that it reduces the number of components necessary to manufacture and operate the sealing apparatus 100, thereby reducing manufacturing costs and rendering the device less susceptible to failure and/or breakdown.
In alternative embodiments, flexible member 124 and/or gripping member 130 may be joined to sealing portion 112 and receiver portion 114 by any suitable connection means, such as for example, epoxy or heat welding. Forming the sealing apparatus using such connection means may allow for considerable manufacturing flexibility. That is, because flexible member 124 and/or gripping member 130 would be injection molded separately, sealing apparatuses 100 having sealing portions 112 and receiver portions 114 of various sizes (e.g., length) may be assembled without requiring fabrication of injection molds/dies for each size.
Additionally, in a released position, flexible member 124 may provide a biasing force to either or both of the receiver portion 114 and sealing portion 112 such that the receiver portion 114 and sealing portion 112 tend to come together. In certain embodiments, the biasing force may be of insufficient magnitude to cause sealing portion 112 to be received in the engagement aperture 116 of the receiver portion 114, but in the released position, in the absence of external forces, the sealing portion 112 and receiver portion 114 may be arranged generally adjacent. That is, sealing apparatus 100 may not achieve the sealed position without additional force being applied to either or both of the receiver portion 114 and sealing portion 112 by a user of the apparatus 100. In this regard, the biasing force created by flexible member 124 is particularly advantageous in that it aids a user in bringing the sealing apparatus 100 into the sealed position.
As shown in
Referring to
Sealing apparatus 100 may be used to seal a bag (not shown). The bag may be a partially sealed envelope having an opening to receive contents into the bag. The sealing apparatus 100, in the released position, is applied to the bag generally proximate to the bag opening with the sealing portion 112 generally parallel to bag opening. As shown in
The bag sealing apparatus 100 may be removed from the bag by grasping a portion of the sealing portion 112 that extends beyond an end of the receiver portion 114, such as for example, the gripping member 124. While grasping the gripping member 124, a force may be applied to the lugs 20 to move the sealing portion 112 through the gap 118 of the receiver portion 114, so that the sealing portion 112 and the receiver portion 114 are again in a released position. The portion of the bag proximate to the bag opening may now be separated from the sealing portion 112 and/or the receiver portion 114 so that an interior portion of the bag may be accessed.
In some embodiments, sealing portion 112, receiver portion 114, and/or the flexible member 124 may be comprised of any semi-rigid or rigid materials that are elastically deformable, such as for example metals and polymeric materials. In certain implementations, sealing portion 112, receiver portion 114, and flexible member 124 may be comprised of the same material, different materials, or any combinations thereof. In one specific embodiment, the sealing portion 112, receiver portion 114, and flexible member 124 be formed from any of a polyurethane, a polyethylene, and/or a polypropylene copolymer.
As shown, sealing apparatus 100 may be formed as a unitary structure. Contrasted with sealing apparatuses having two or more separate components, the sealing apparatus 100 of the present disclosure has several advantages. For example, the unitary structure accommodates sealing of a bag with only one hand. That is, using only one hand, a user may thread the opening of a bag between the spaced apart sealing portion 112 and receiver portion 114, and then using only the same hand, may impress the receiver portion 114 against the sealing portion 112 to achieve the sealed position. As a further example, the unitary structure provides an organizational benefit in that users of the sealing apparatus are not burdened with the task of keeping track of several separate components in order to successfully operate the sealing apparatus 100.

The foregoing embodiment offers numerous advantages over the prior art. For example, since the sealing portion 12 and the receiver portion 14 are advantageously formed as single components having no moving parts, they may be relatively inexpensively produced. Further, since the disclosed sealing apparatus is not integrally formed with a bag, or other enclosure device, it may be used on a wide variety of bags, and also allows repeated use. Thus, the foregoing embodiment, in particular, avoids the shortcomings associated with the ZIP-LOC closure.
From the above description and drawings, it will be understood by those of ordinary skill in the art that the particular embodiments shown and described are for purposes of illustration only and are not intended to limit the scope of the present invention. Those of ordinary skill in the art will recognize that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. References to details of particular embodiments are not intended to limit the scope of the invention.
