The present invention relates to shopping bags, and in particular, to shopping bags with no back face crease, that are thin when folded.
Shopping bags are commonly used the world over as receptacles for purchased items. They come in many sizes, colors, and patterns.
Although such a prior art shopping bag 2 is widely used, it suffers from at least three major disadvantages. First, as shown in
Some efforts have been made to address some of these disadvantages. Barney's New York, for example, uses a shopping bag that does not include a fold or bottom panel4. Although this means that the shopping bag lies much more flat that prior art shopping bag 2 shown in
Therefore there is a need for a paper shopping bag that includes the advantages of the prior art in that it includes a bottom panel 4, so that the shopping bag may sit upright when open and has plenty of room to expand, but overcomes the disadvantages of the prior art in that it lies flat, has front and back panels that are never covered by a bottom panel when folded, and does not include a crease on either front or back panel, such as bottom flap crease 8, that will tend to make the shopping bag list.
The present invention includes three unassembled bags, and an assembled bag.
In its most basic form the first unassembled bag of the present invention is a creased piece of paper including top and bottom parallel horizontal sides that are perpendicular to right and left vertical sides; a bottom left corner where the bottom horizontal side meets the left vertical side; a bottom right corner where the bottom horizontal side meets the right vertical side; left, middle, and right parallel vertical creases; top and bottom horizontal creases; right, middle, and left intersections where the right, middle, and left vertical creases and bottom horizontal crease meet; right and left side creases parallel to the vertical creases; right and left side crease termini where the right and left side creases and the bottom horizontal side meet; four diagonal creases spanning between the bottom horizontal crease and the bottom horizontal side; a front panel flange crease parallel and adjacent to one of the vertical sides; a front panel flange intersection where the front panel crease and the bottom horizontal side meet; and a front panel flange with an interior and an exterior, one of which has adhesive. The creased paper may be made of any type of foldable paper or cardboard, but is preferably made of those types of paper commonly used to manufacture shopping bags, especially the thick, high quality paper often used to manufacture shopping bags for high end or luxury stores. The creased paper may be assembled to form a bag that may sit upright when open and may lie essentially flat when folded. It is understood that for features of the present invention, such as various creases and sides, to be considered “adjacent,” the features must be parallel to one another and there must not be another parallel feature between the adjacent features.
Each crease in the creased paper is either an “away” crease or a “toward” crease. That is to say that when one views one side of the creased paper, an away crease is creased so that the point of the crease points away from the viewer, and a toward crease is creased so that the point of the crease points toward the viewer. All creases herein designated as away or toward are done so based upon the assumption that the viewer is viewing the creased paper's interior side, or the side that would be the interior of the bag if the creased paper were assembled into a bag. It is understood that if the viewer were viewing the creased paper's exterior side, or the side that would be the exterior of the bag if the creased paper were assembled into a bag, then the away or toward designations would be reversed.
The creases of the creased paper delineate what will be front and side panels of the bag that may be formed from the creased paper. Front panels are generally larger than side panels, although side panels may be up to the same size as front panels. Front panels are flat, while side panels have a crease in the middle for gusseting purposes. The first front panel is formed between the top horizontal crease, the bottom horizontal crease, and two adjacent vertical creases. Depending on the configuration of the creased paper, these may be the left and middle vertical creases, or the middle and right vertical creases. The second front panel is formed between the top horizontal crease, the bottom horizontal crease, the vertical crease that does not form the first front panel, and whatever vertical feature is adjacent to that vertical crease that is not a side crease. This vertical feature may be a vertical side, a front panel flange crease, or a fourth vertical crease. Side panels are formed around side creases and between front panels. The right and left side creases are the creases in the middle of side panels. In all configurations of the creased paper, one side panel is roughly in the middle of the creased paper between the two front panel sections. The other side panel may be on either the extreme left or right of the creased paper. It may also be on the extreme left or right of the creased paper but for the front panel flange. It may also be divided so that one half of the side panel is on the extreme left or right of the creased paper and the other half is on the other extreme side, but for the front panel flange.
The front panel flange is a flange that protrudes from a vertical crease, either a right or left vertical crease or a right or left side crease, of the creased paper and will be adhered to another side or crease of the creased paper to form the body of the bag. The front panel flange therefore creates an adhesive seam. This seam can be located in several places. In a first embodiment, the front panel flange is on the right between the right vertical side and the right side crease so that the front panel flange crease and the right side crease are the same toward crease. In this embodiment, the first front panel is formed between the middle and right vertical creases; the second front panel is formed between the left vertical crease and a fourth vertical crease adjacent to the left vertical side; and a side panel is split with half of it between the left vertical side and the fourth vertical crease, and half of it between the front panel flange crease/right side crease and the right vertical side. The mirror image of this configuration is another embodiment: The front panel flange is on the left between the left vertical side and the left side crease so that the front panel flange and the left side crease are the same toward crease. In each of these first mirror image configurations, the adhesive seam will be in the center of one of the side panels of the bag when the creased paper is assembled into a bag.
In a second embodiment, the front panel flange is an away crease on the right between the right vertical side and the right vertical crease, but the front panel flange crease is not the same as a side crease. In this embodiment, the first front panel is formed between the left and middle vertical creases; the second front panel is formed between the right vertical crease and the front panel flange crease; and a side panel is formed on the extreme left between the left vertical side and the left vertical crease. Again, the mirror image of this configuration is another embodiment: The front panel flange is on the left between the left vertical side and the left vertical crease, but the front panel flange crease is not the same as a side crease. In each of these second mirror image configurations, the adhesive seam will be between a front panel and a side panel because the front panel flange is protruding from a front panel and being adhered to a side panel. In each of the first and second embodiments discussed above, the front panel flange is being adhered to a half of a side panel that includes a diagonal crease at its bottom. In these configurations, therefore, the front panel flange also includes a partial diagonal crease at its bottom so as to conform with the side panel and its diagonal crease. In some embodiments, the front panel flange is commensurate with half of a side panel, so it includes a full diagonal crease that conforms with the side panel's diagonal crease. Therefore, it is understood that a “partial diagonal crease” may be as long as the first through fourth diagonal creases.
In a third embodiment, the front panel flange crease is on the right between the right side crease and the right vertical side. In this embodiment, the first front panel is formed between the middle and right vertical sides; the second front panel is formed between the left vertical side and the left vertical crease; and a side panel is on the extreme right but for the front panel flange. Again, the mirror image of this configuration is another embodiment: The front panel flange is on the left between the left side crease and the left vertical side. In each of these third mirror image configurations, the adhesive seam will again be between a front panel and side panel, this time because the front panel flange is protruding from a side panel and being adhered to a front panel. In this embodiment, as the front panel flange is being adhered to a front panel that does not include a diagonal crease, there is no need for the front panel flange to include coinciding partial diagonal creases.
In preferred embodiments of the present invention, the unassembled bag also includes a bottom reinforcement. The bottom reinforcement is approximately the same area as what the bottom of the bag will be, which is twice the area of the space defined by two adjacent vertical creases, the bottom horizontal side, and the bottom horizontal crease. The bottom reinforcement is connected to a bottom reinforcement flange, which is adhered to just above the bottom horizontal crease. The bottom reinforcement and the bottom reinforcement flange are separated by an away bottom reinforcement crease that conforms with the bottom horizontal crease.
In preferred embodiments of the present invention, the unassembled bag also includes a bottom panel flange protruding from the bottom horizontal side. This is not to be confused with the bottom reinforcement flange, which adheres the bottom reinforcement to the creased paper. The bottom panel flange adheres the creased paper to itself to form the bottom panel on which the bag will sit. The bottom panel flange may be positioned below either front panel. That is to say, depending on the configuration of the front panel flange, the bottom panel flange may be positioned between the middle and right vertical creases; the middle and left vertical creases; the left vertical crease and a fourth vertical crease adjacent to the left vertical side; the right vertical crease and a fourth vertical crease adjacent to the right vertical side; the front panel flange crease and the left vertical crease; the front panel flange crease and the right vertical crease; the left vertical side and the left vertical crease; and the right vertical side and the right vertical crease. The bottom panel flange includes an exterior side and an interior side, one of which includes a bottom panel flange adhesive. If the bottom panel flange adhesive is on the interior of the creased paper, then the flange will be visible on the bottom of the exterior of the bag that may be assembled from the creased paper.
It is therefore preferred that the bottom panel flange adhesive be on the exterior of the bottom panel flange, so that the bottom panel flange is tucked into the interior of the bag during assembly and is therefore not visible from the exterior of the bag. In one such embodiment, the bottom panel flange adhesive is an adhesive strip, i.e. a strip of adhesive, usually some type of glue, that is covered with a non-adhesive strip until directly prior to adhesion, when the non-adhesive strip is peeled away to reveal the strip of adhesive which is then adhered to something else. It is preferred that the adhesive strip be as long as the bottom panel flange, but not as wide, and that it be positioned adjacent to the bottom horizontal side. This avoids any unsightly adhesive seeping through the seam because if it does stray, it will only stray farther along the bottom panel flange, rather than to the exterior of the bag.
In some embodiments of the unassembled bag, particularly those made with stiff or thick paper, the diagonal creases of the creased paper may be perforated, in addition to being creased.
Preferred embodiments of the unassembled bag also include top reinforcements positioned below the top horizontal crease and handles positioned so that they are attached to the creased paper at the top reinforcements. Top reinforcements are preferably thin rectangular pieces of cardboard, but may be any shape and may be any of a range of thicknesses. Although thin rectangular cardboard top reinforcements are preferred, the top reinforcements may be made of paper, either the same paper as the bag is itself manufactured out of or other paper.
The handles may be cut into the top of the front panels so that they are essentially holes in the top of the front panels. They may be cord, string, wire, ribbon, rope, thread, or any other type of string, whose ends are adhered to the interior of the front panels. They may be pieces of string that are tied in knots at their ends and threaded through holes in the front panels. These are but a few examples of the many handles commonly used in the art of shopping bags that are contemplated as falling within the scope of the present invention. Regardless of the type of handles, it is preferable that the bag be reinforced where the handles meet the front panel. This reinforcement may be by folding the creased paper at the top horizontal crease, including top reinforcements, or both.
The second unassembled bag of the present invention includes two pieces of creased paper that may be assembled into a bag. Such a two piece assembly would likely be used for larger bags, although it may be used for any sized bag. Many of the features of the first creased paper kit are in common with the creased paper of the present invention. Each piece includes left and right vertical sides, top and bottom horizontal sides, bottom right and left corners, top and bottom horizontal creases, left and right intersections where the left and right vertical creases meet the bottom horizontal crease, a front panel flange formed by a front panel flange crease, positioned on one side of the piece, a front panel intersection where the front panel flange crease meets the bottom horizontal side, and two diagonal creases spanning diagonally between the bottom horizontal crease and the bottom horizontal side. The front panel flanges on either the left or right sides of the two pieces will adhere to the other piece at what will become a side panel when the creased papers are assembled into a bag. In the preferred embodiment, this makes the adhesive seam along the center of the side panel. As discussed above, in this preferred embodiment, as the front panel flange is being adhered to a side panel, it must include a partial diagonal crease to conform with the diagonal creases of the side panels.
In a second embodiment of the two piece unassembled bag, each piece includes only a one vertical crease, and also includes a side toward crease adjacent to the vertical crease and the front panel flange crease. This second embodiment encompasses two mirror images. In the first mirror image, the left vertical side is adjacent to the vertical crease, which is adjacent to the side crease, which is adjacent to the front panel flange crease, which is adjacent to the right vertical side, so that the front panel flange is on the right. In the second mirror image, the left vertical side is adjacent to the front panel flange, which is adjacent to the side crease, which is adjacent to the vertical crease, which is adjacent to the right vertical side, so that the front panel flange crease is on the left. In these embodiments, the side panels are not split, and the front panel flanges extend from the side panels for attachment to the front panels, so the front panel flanges do not include partial diagonal creases.
In a third embodiment of the two piece unassembled bag, each piece also includes only a one vertical crease, one side toward crease adjacent to the vertical crease, and the front panel flange crease. This third embodiment also encompasses two mirror images. In the first mirror image, the left vertical side is adjacent to the front panel flange crease, which is adjacent to the vertical crease, which is adjacent to the side crease, which is adjacent to the right vertical side, so that the front panel flange is on the left. In the second mirror image, the left vertical side is adjacent to the side crease, which is adjacent to the vertical crease, which is adjacent to the front panel flange crease, which is adjacent to the right vertical side, so that the front panel flange crease is on the right. In these embodiments, the side panels are not split, and the front panel flanges extend from the front panels for attachment to the side panels, so the front panel flanges include partial diagonal creases.
The third unassembled bag of the present invention includes four pieces of creased paper that may be assembled into a bag. Such a four piece assembly would also likely be used for larger bags, although it may be used for any sized bag. The four piece creased paper kit includes two panel pieces, two side pieces, and four attachment flanges that will be integral to either side of the two panel pieces, either side of the two side pieces, or the right or left sides of the two panel pieces and two side pieces. When the attachment flanges are attached only to side pieces or panel pieces, each set of attachment flanges includes a right attachment flange and a left attachment flange. The right attachment flange will be integral to either the right side of each side piece or the right side of each panel piece. The right attachment flange includes a right side that will be the far right side of the combination of the attachment flanges with either a side or panel piece, and a left attachment side that shares a toward crease with the right side of the side or panel piece. The left attachment flange includes a left side that will be the far left side of the combination of the attachment flanges with either a side or panel piece, and a right attachment side that shares a toward crease with the left side of the side or panel piece. When the attachment flanges are integral to the panel pieces, they include partial diagonal creases to conform with the diagonal creases of the side pieces. When the four attachment flanges are attached to the left sides of each of the four pieces, the attachment flanges each include a left side and a right attachment side, and the two attachment flanges attached to the panel pieces for attachment to the side pieces include partial diagonal creases. When the four attachment flanges are attached to the right sides of the four pieces, the attachment flanges each include a right side and a left attachment side, and the two attachment flanges attaches to the panel pieces for attachment to the side pieces include partial diagonal creases.
The bag of the present invention includes an exterior, an interior, a front panel, a back panel, two side panels, and a bottom panel. The front, back, and side panels include top sections that are folded over into the interior of the bag. This creates a top fold. The top fold includes a centered slit cut into the fold. The bag also includes an integrated handle and top reinforcement with a handle section, a handle width, a top reinforcement section, and a top reinforcement width. The integrated handle and top reinforcement is designed to slide through the centered slit to provide handles for the bag. The centered slit is wider than the handle width so that the handle section may move through the centered slit, but is narrower than the top reinforcement width so that the top reinforcement section cannot move through and is caught by the centered slit. Being able to insert the handles into the bag decreases the size necessary for shipping the bags. This type of handle may be used in conjunction with any of the unassembled bags of the present invention as described above.
Therefore it is an aspect of the present invention to provide an unassembled bag that may be formed into a bag with adhesive seams at any of several positions.
It is a further aspect of the present invention to provide an unassembled bag that may be assembled into a bag that includes a bottom reinforcement and a bottom reinforcement flange that is adhered to the interior of a front panel of the bag.
It is a further aspect of the present invention to provide an unassembled bag that may be assembled into a bag that is assembled in part by a bottom panel flange that may be in any of several positions.
It is a further aspect of the present invention to provide an unassembled bag that may be assembled into a bag that includes a bottom panel flange with a strip adhesive that will not be on the exterior of the assembled bag.
It is a further aspect of the present invention to provide a two piece unassembled bag that may be assembled into a bag.
It is a further aspect of the present invention to provide a four piece unassembled bag that may be assembled into a bag.
It is a further aspect of the present invention to provide a bag with top reinforcements and several different types of handles.
These aspects of the present invention are not meant to be exclusive and other features, aspects, and advantages of the present invention will be readily apparent to those of ordinary skill in the art when read in conjunction with the following description and accompanying drawings.
