1. Field of the Disclosure
The present disclosure is generally directed to food storage articles, and more particularly to a wrap product that can be used to store food items.
2. Description of Related Art
Conventional storage articles are known for storing food items and the like, and are typically either of a substantially rigid plastic configuration, thin film cling or foil sheet configuration, or a flexible bag configuration. Plastic containers of this type typically have a base and a lid. The base has a bottom and a side wall that defines a storage space. The lid snaps onto the base to seal the storage space. The lid and base of this type of plastic container typically remain in the same configuration at all times.
Thin film sheet materials typically come in rolls of sheet material that can be separated into individual wrap products. Plastic film sheet is commonly of the self-cling variety where the material can be folded unto itself and will cling to itself until being physically unwrapped or separated. Thin metal foil sheet is typically very bendable and capable of retain whatever shape into which it is bent.
Bag type storage containers are typically made of paper or a flexible, transparent, plastic material. These types of bags have a storage space within wall panels of the bag. Some bags have only two non-pleaded panels that are connected to one another along three sides, leaving an opening on a fourth side and forming a square or rectangular flat configuration. Some bags have pleats and more than two side panels and are formed so that the bag can expand between the two larger, primary side walls to create a greater volume and/or to hold larger objects than can not fit in a simple, two-panel, non-pleated bag.
All of these types of common storage products are utilized to store food items. In one example, people use these types of products to store their lunch, which often can include a sandwich. Many people prepare their lunch at home and then carry their lunch to their work place or to school for consumption later in the day. There are a few prescribed steps that most people generally follow when preparing their lunchtime sandwich. One step is to clear a prep surface to keep the sandwich fixings and the work space clean while preparing their sandwich and other lunch items. Another step is to prepare the sandwich and other lunch items on the prep surface. A further step is to then place their sandwich and perhaps other lunch items in either a rigid plastic container, one or more thin wrap sheets, or in a flexible sandwich or lunch bag. The sandwich and other lunch items are then placed in another container, such as a lunch box, briefcase, purse, plastic bag, brown paper bag, or other soft-sided container. Then, of course, the sandwich is removed along with the other lunch items and consumed later in the day away from the home environment. The typical empty storage container is then either thrown away or transported back home to be re-used.
One problem with conventional rigid plastic containers is that the containers must be carried back home. The container takes up as much space whether traveling to or from work or school, even though there is typically nothing left in the container on the return trip. The container then is cleaned and reused another time. The flexible bag type container offers virtually no protection for the food stored in the container from contact with other items. Often the food item, such as a sandwich, can become squished or damaged during transport or other activities prior to the lunch or food items being consumed. Similar problems are common for thin metal foil or plastic cling wraps. These thin wrap sheets can be used as a food prep surface, but are not durable enough to withstand any type of contact with food prep tools such as knives. A rigid plastic container offers projection to the food items but is not typically disposable and, thus, is transported to and from different locations for use. The soft-sided storage bags or thin wrap materials typically offer no physical protection for the food items. Additionally, none of these products offers any type of durable food preparation surface or space that can be used to prepare the food items that will be transported in the containers. The user must first free up a space on a table or countertop and clean off that surface prior to food preparation.
Objects, features, and advantages of the present invention will become apparent upon reading the following description in conjunction with the drawing figures, in which:
Various examples of food storage wraps are disclosed herein that solve or improve upon one or more of the above-noted and other problems and disadvantages with prior art food storage products. The disclosed food storage wraps can be configured to offer a food preparation surface when unfolded. The disclosed wraps also can offer some physical protection during transport and storage of the food contained within the wrap. The disclosed wraps also can offer an eating surface after re-opening the wrap while the food is being consumed. The disclosed wraps also are conveniently disposable after use. The disclosed wraps also can be configured to include one or more closure features that assist in securing the wrap around a food item held within the wrap.
Turning now to the drawings,
In the disclosed example, the carrier sheet 22 has a pair of side edges 24 that define a length of the rectangular carrier sheet 22. The carrier sheet 22 also has a pair of end edges 26 that define a width of the carrier sheet. The carrier sheet can be constructed from any suitable, flexible material. In one example, the carrier sheet can be made from a thin film plastic sheet that has at least some degree of cling properties so that the material easily and readily clings or sticks to itself when folded. Also, the plastic material of the carrier sheet 22 can be clear or transparent or can at least be translucent, if it is desired to see the food item stored in the wrap. In another example, the plastic material can be provided in different colored thin film sheet material, whether opaque or transparent.
In one example, the plastic carrier sheet material can be a polyethylene (PE). However, the carrier sheet can be formed from other suitable materials as well. For example, a thin metal foil material can be used for the carrier sheet material. Such materials can be bent and retain their shape, which can assist in the sheet staying wrapped around a food item. In other examples, the carrier sheet 22 can be formed from paper products including recycled paper, coated paper, and readily sustainable paper products such as sugar cane or potato based paper products.
The wrap 20 also includes a prep panel 30 that is carried on the carrier sheet 22. The prep panel 30 in this example is formed as a laminate structure from materials that result in a structure that is less flexible than the carrier sheet. In the disclosed example, the prep panel 30 has two generally flat prep sections 32a and 32b that are longitudinally aligned with one another relative to the length of the carrier sheet 22. Each disclosed prep section 32a, 32b is generally a square shape (with rounded corners) and has one edge 34 spaced from but adjacent to the similar edge 34 of the other prep section. In this example, an intermediate strip 36 is positioned between the edges 34 of the prep sections 32a, 32b and is interconnected along a joint to each of those edges. In one example, the joint between the edges 34 of the prep sections 32a, 32b and the intermediate strip 36 can be scored, formed with intermittent gaps, or formed as a frangible connection to facilitate folding for purposes as described below.
The prep panel 30, or at least the prep sections 32a, 32b as shown in this example, can be formed with at least their exposed surfaces formed from a food-safe material. In an alternate example, or in combination with the food-safe characteristics, the prep sections 32a, 32b or the entire prep panel 30, can be formed with the exposed surfaces having non-stick characteristics such as a wax paper finish or the like. As shown in
In the disclosed example, the layers 40a, 40b and 38 are adhered to one another on the same side of the carrier sheet 22. As shown in
In this example, the prep panel 30 is configured having a slightly hourglass shape with each of the two prep sections 32a, 32b having a first width and the intermediate strip having a width slightly less than the prep sections. The structural layers 40a, 40b and 44a, 44b in these examples lie positionally aligned with a respective one of the food layers 38 and 42, whether lying directly against the food layer or with the carrier sheet 22 positioned between the two layers. Also as shown in
Also, the prep panel 30 and/or its various layers or surfaces can be adhered to the carrier sheet 22 using any suitable adhesive, material, or process. In one example, the prep panel 30 is simply adhered to a surface of the carrier sheet 22 using a suitable adhesive carried on one or more of the surfaces of the various parts of the wrap structure, depending on the construction and configuration of the wrap 20.
Also as shown in
In each of these disclosed closure feature examples, the closure features assist in retaining the wrap 20 around a food product during use. This helps in keeping the food product fresh while it is stored in the wrap. In another example, the closure features can alternatively, or in addition to the twist ties or papers strips, be created by the dinginess of the material of the carrier sheet 22 to itself. Thin film plastic materials are known for food preparation purposes that employ a pressure sensitive characteristic as a part of the exterior surface of the sheet. Conventional plastic wraps also have substantial dinginess so that the material sticks to itself when folded onto itself around a food product. The cling nature of the carrier sheet 22 can be incorporated as the sole closure feature or in combination with one or more additional closure features, such as the twist tie or the self adhesive paper strip arrangements described herein. Some thin film plastic sheets are completely clear or transparent and the material can and will readily stick to itself when one portion of the sheet comes in contact with another portion of the sheet. Other types of thin film sheets may require the application of some pressure to a surface of the sheet when in contact with another part of the sheet, whereby the pressure creates adhesion between the two surfaces of the sheet. As will be evident to those having ordinary skill in the art, the particular material used to fabricate the carrier sheets disclosed herein can vary considerably and yet fall within the spirit and scope of the present invention. The degree of dinginess and the manner in which it can be achieved in the wrap can also vary.
The size, particular configuration, and placement of the prep panel 30 on the carrier sheet 22 can also vary and yet fall within the spirit and scope of the present invention.
For example,
As discussed above, the prep panel structure 30 can be altered relative to the carrier sheet and yet fall within the spirit and scope of the present invention. For example,
Once the sandwich is prepared, the wrap can be folded around the sandwich. As shown in
The stored sandwich shown in
As shown in
The various examples of food storage wraps disclosed herein can be manufactured using any suitable process. In one of numerous possible examples, the cling wrap or thin film sheet material can be continuously extruded or otherwise let out. The prep panel structures can also be continuously formed, cut, laminated, unrolled, let out, and/or extruded in a separate process. The sheet and prep panel layer can be fabricated simultaneously and adjacent to one another, if desired, so that the prep panel material strip and the thin film material strip of the carrier sheet can be laminated, adhered, or otherwise attached to one another in a continuous process. The continuous laminate strip of wraps can then either be cut into individual wraps and laid in piles for packaging or can be left in a continuous strip. Such a continuous strip can be formed with spaced apart perforate or frangible tear lines in the strip material to segregate and define each of the wraps. Such a perforate strip of wraps can then be rolled and packaged for the consumer. The consumer can pull the strip from a package and tear off individual wraps as needed. Clearly, other processes can also be utilized to fabricate the disclosed wraps and yet fall within the spirit and scope of the present invention.
As noted above, the prep panel surfaces and the prep panel structures can vary in size and configuration to accommodate different sized and shaped food items. The disclosed wrap configurations and constructions are described to accommodate a sandwich. However, other food items can also be accommodated in the design of the wrap products. For example, a circular prep panel configuration with scored edges that can fold upon one other can be created to form a shell or dish in conjunction with a thin film sheet. The structure can be folded similar to the wraps disclosed and described herein to produce an on-the-go container for storing miscellaneous food items such as fruit slices, chips, or the like. Structural layers of the disclosed prep panels can also be configured, if desired, to fold up around a specific type of food item to provide specific crush protection. A folded structural panel can be configured to fold up and form structural side panels oriented perpendicular to the primary top and bottom prep section layers. The intermediate strip 36 described herein offers one example of such a panel that can be oriented differently than the primary prep sections 32a and 32b of the disclosed prep panel structure.
The disclosed food storage wraps 20, 120, 130, 140, 150, 160, and 170 each provide a single product that can be used by consumers to prepare, store, transport, and consume a food item that is prepared at one time in the day, perhaps transported to a different location, and consumed later in the day. The wraps are conveniently disposable and inexpensive to manufacture. The wraps can provide essentially the same advantages as a known storage bag or plastic container and yet are easier to fill and unwrap. The disclosed wraps, when storing food, can take on nearly the exact shape of food item, similar to many storage bags. Additionally, the structural nature of the disclosed prep panels provides a degree of crush protection similar to a rigid storage container and yet avoids the disadvantages of storing and transporting food in a rigid container.
The various closure features described herein provide at least two functions. First, the examples disclosed herein securely hold the wrap in the in-use or folded storage configuration. This can enhance keeping the food fresh and keeping the wraps secured around the food item for continued crush protection until the food is consumed. Second, the twist ties, adhesive strips, and other closure features can also be formed having some structural rigidity. The various disclosed strips can help manage the cling film carrier sheet 22 and keep it in a flat form during food preparation and food consumption. The relatively stiff or structural nature of these types of closure features can inhibit the film from clinging to itself and assist in holding the ends of the wrap in the flat condition.
The various disclosed wraps also help to reduce the number of food preparation steps. There would be no need to use and dirty extras dishes because the wraps themselves provide the food preparation surface. The disclosed wraps also offer many of the advantages of both food storage bags and plastic storage containers. The wraps described herein are disposable and offer significant space efficiency, just as food storage bags provide. The disclosed wraps also provide crush protection for the stored food items, just as rigid plastic storage containers provide. The disclosed wraps also offer improved functionality over conventional, known, cling film wrap products currently on the market today. The disclosed wraps offer better value and more convenience than such plastic wraps products. The addition of the prep panel 30 assists in holding the wrap in the unfolded condition for food preparation and consumption and provides crush resistance. The prep panel structures also provide a food preparation surface and a food consumption surface that stays flat and resists cutting. Conventional known wrap products do not offer such advantages.
Conventional food storage bags are often considered to have advantages over rigid plastic food storage containers. A bag can be configured to a very compact size and shape when not in use. A bag can also conform to nearly the size and shape of any stored contents when in use, thus taking up potentially less space for storing a food product. Consumers also feel that a bag is truly disposable. The disclosed wraps of the invention offer these very same advantages. Rigid containers retain the same size and shape whether in use or not. Rigid containers take up the space no matter the size or shape of any stored contents. Even if a rigid container is intended to be disposed of, consumers often do not do so and instead retain the container unnecessarily. Consumers often do not like to transport empty rigid containers back home for reuse, but feel obligated to do so. These disadvantages of rigid containers are avoided in the disclosed food storage wraps of the invention.
Rigid food storage containers are often considered to offer at least one big advantage over food storage bags. The access opening to the storage space of a rigid container is relatively large and typically retains its shape for the user when filling the container with a food product. Flexible storage bags are often difficult for a user to fill because of their flexible structure and the lack of a consistent size and shape opening into the bag. When filling a conventional food storage bag, a user must often hold the bag upright or open with one hand, leaving only hand free to fill the bag. This can be particularly difficult when transferring contents to a food storage bag from a heavy or large pot or other cooking vessel. Some pleated food storage bags may function somewhat more similarly to a brown paper grocery bag. This feature may in some instances help the storage bag to stay open while being filled. However, the pleated storage bag does not help to create a large, stable, rigid opening to facilitate dispensing or filling the bag. As soon as the bag is tilted for dispensing, or as soon as contents hit the flexible side walls of the bag, the opening can close or change significantly in size and shape. This can make filling and dispensing even a pleated bag rather difficult. Rigid containers alleviate these concerns. The disclosed wraps are fully unwrapped when being filled and thus eliminate the filling problems of conventional storage bags and achieve the crush resistance benefit of the rigid container. The disclosed wraps also offer the above-noted advantages over conventional food wrap products.
Rigid storage containers offer physical, structural protection for food items stored in a container. The disclosed wraps can be fabricated to offer at least some degree of physical protection for the stored food items. This feature can be enhanced or minimized, depending on the particular structure and materials used to create the prep panel structures 30, 152, 162, and 172 disclosed herein.
As mentioned above, food storage bags and conventional cling wrap material have an advantage over rigid food storage containers in that they are typically disposable after one or only a few uses. Consumers typically have no problem disposing of these types of food storage products. Although there are several types of disposable, “semi-rigid” food storage containers formed having a thin-wall structure, these are otherwise still viewed as a more durable, rigid, reusable container. Such disposable “semi-rigid” containers take up just as much space in a waste container as when they are in use. Thus, consumer will often choose to clean and reuse these types of containers instead of throwing them away. Through interviews with consumers, these factors combine to make many consumers uncomfortable with throwing away “disposable” semi-rigid food storage containers, which are commonly in use today. Because consumers are less likely to clean bags and wraps and because they take up little space in the garbage, consumers feel bags are more suited to one-time usage. The disclosed wraps are fully disposable and are much more similar to conventional cling wrap sheet material and storage bags because they do not have a true rigid nature. Thus, a consumer typically will have no problem disposing of the disclosed wraps after use.
Although certain food storage wraps have been described herein in accordance with the teachings of the present disclosure, the scope of coverage of this patent is not limited thereto. On the contrary, this patent covers all embodiments of the teachings of the disclosure that fairly fall within the scope of permissible equivalents.
