Description
TITLE OF THE I~V~N110N 2 0 6 7 g ~ 4 IMPROVED PLEATED PACKAGING WRAPPER AND METHOD OF
WRAPPING OBJECTS USING THE SAME
BACKGROUND OF THE 1NV~N11ON
This invention pertains to a pleated packaging useful for wrapping various objects, such as sandwiches, or other foodstuff, and method of using the same.
Description of the Prior Art In U.S. Patent No. 4,795,648 there is described a packaging made from a thin sheet which is pleated and the borders of its pleats are affixed to one another by various methods. The pleats are knife pleats. The dimensions of the pleats are selected to conform to the nature of the object to be packaged and with the distance between the welds. The pleats are fixed at the ends, and are free at the middle, such that when they are opened up they form a hollow shape which is suitable for wrapping round sandwiches and the like. The patent describes a method enabling this type of shape to be obtained from a flat sheet by making parallel knife pleats - 1 - ~' which give the folded wrapping a substantially planar configuration that is bulked up by unfolding.
In U.S. Patent No. 5,188,265 issued February 23, 1993, a more generalized structure is described for pleated packaging.
However, when the packaging constructed as described above was tested, it was found there was some difficulty in using the packaging to wrap certain objects especially if the objects were fragile such as, for example, sandwiches. Thus wrapping fragile objects required more training, and was time consuming.
Moreover, it was found that certain wrapping such as for hamburgers require reinforcement to protect the hamburger against crushing and to resist vertical forces.
SUMMARY OF THE lN V~N'LlON
It is an objective of the present invention to provide a pleated packaging which is easier to use.
A further objective is to provide pleated packaging which can be used to wrap fragile objects such as sandwiches, tacos and other food stuff.
Yet a further object is to provide a packaging which provides support and protection to the wrapped object so that the object is not damaged while it is being carried.
Other objectives and advantages of the invention shall become apparent from the following description.
.
A packaging constructed in accordance with this invention includes a pleated zone consisting of a series of parallel pleats with a central region, and a straight zone dimensioned to fit at least partially around the object. The object is first placed on the straight zone, after which the pleated zone is expanded and trained around the object to complete the packaging. The straight zone may be made of a stiff material such as cardboard to protect the object. The packaging of different shapes and sized may be made to fit around hamburgers, tacos, etc.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to Figure 1, a packaging constructed in accordance with this invention is generally a flat relatively thin sheet composed of two zones 1 and 13. Zone 13 is generally rectangular and is formed by taking a sheet of paper, or other material, and folding it to form sequential pleats. Zone 13 has a width 8 which in this embodiment is smaller than the dimension 4 of zone 1. Zone 1 is unpleated, or straight and is joined adhesively or by other means to zone 13.
In a preferred embodiment of the invention, the packaging consists of a layer of paper coated with a plastic material such as polyethylene. Thus, zone 1 includes an upper layer or face 15 of polyethylene and lower layer or face 30 of paper.
In the embodiment of Figure 1, zone 1 is attached by using an adhesive, or any other similar means, to the border section 14 20679~
of zone 13, wherein the polyethylene layer lS of zone 1 contacts the paper layer 16 of zone 13.
The dimensions 3 and 4 of zone 1 are selected so that zone 1 can at least partially cover the object to be wrapped. For S example, Figure 2 shows a generally cylindrical object which may be sandwich such as a hamburger 31, having a generally round top with a diameter 10. Hamburger 31 is wrapped by first positioning the packaging so that zone 1 is disposed peripherally around the hamburger 31 with the polyethylene layer contacting the hamburger. The zone 1 is then folded over the hamburger top 31 and bottom (not shown). The wrapping is completed by pulling on the zone 13 longitudinally so that the pleats open at their central region disposed adjacent to the side of the hamburger and training zone 13 around the hamburger until the hamburger is totally enclosed. The closed regions of the pleat form the top 12 of the wrapping, except for circular opening 11. At opening 11, the hamburger may be covered by the edges of zone 1.
It was found that the packaging shown in Figure 1 can be used easier and faster then a packaging formed of a completely pleated material. Moreover it is easier for the customer to hold the hamburger using the straight, unpleated zone 1.
The embodiment of Figure 4 is similar to the previous embodiment but it is made up of a single sheet composed of a pleated zone 13 and a straight zone 9. In this embodiment, the two zones 9, 13 have widths 7, 8 respectively which are substantially the same. As discussed in U.S. Patent No.
4,795,648, a pleated packaging is made from a sheet folded to make pleats 13. The pleats are secured by two fixation bands, A
and B or other securing means. Advantageously, the embodiment of Figure 4 can be made by first making a pleated sheet and then opening the pleats before fixation bands A, B are applied.
Alternatively, the packaging may be made from a single sheet by not forming the pleats in zone 9 at all. The packaging of Figure 4 may have, for example, an overall length and width in the range of 5.86"-6.25". The pleated zone 13 may consist of about 10-12 pleats, each pleat being formed by two sheet folds having a width of 0.58" and 0.39" respectively.
The embodiment of Figure 4 is particularly suited for wrapping relatively flat, semicircular objects, such as a taco.
As shown in Figure 4, a taco 6 is first placed on the top half of zone 9. Zone 9 is formed so that its length exceeds the length 5 of the taco 6. The whole packaging is then folded over to partially cover the taco, as seen in Figure 5. Preferably the width 7,8 of the packaging is smaller than the width of the taco.
In the configuration of Figure 5, a portion of the taco thus extends above the packaging. The taco is then finally wrapped by pulling longitudinally on zone 13 as indicated in Figure 5 by arrow L and then training zone 13 around the taco 6 and zone 9 as indicated by arrow M. The final closed wrapping is shown in Figure 6.
The packaging of Figures 4-6 has the same advantages as the wrapping of Figures 1-3, except that it is more suitable for tacos. More specifically, a customer can easily remove the zone 13 and use the remaining zone 9 to hold the taco during eating.
In the embodiment of Figures 7 and 8, zones 13, 1' are adhesively secured along border 17 with the polyethylene layer 15 facing the polyethylene layer 13' of zone 13. Before an object is wrapped in this packaging, the two zones are unfolded as shown in Figure 8. The object is then placed on zone 1' and zone 13 is then wrapped around the object as in the previous embodiment.
The embodiment of Figures 9 and 10 is composed of a pleated zone 13 and a straight, unpleated zone 18 which may be secured to zone 13 in a manner similar to zone 15 in Figures 7, 8. While pleated zone 13 is made of a relatively thin film which is easily pleated, zone I8 is made of stiffer material, such as cardboard coated with a plastic material. The width 19 of zone 18 is selected to correspond to the height of the object to be wrapped.
Moreover, while zone 13 expands in its central region in length while it is being opened, the length of zone 18 remains the same.
Thus prior to wrapping, the zone 18 is longer than zone 13. As shown in Figure 10, the packaging of Figure 9 is wrapped around a hamburger 24 so that zone 18 is disposed peripherally around the side of the hamburger. In this manner zone 18 forms a protective wall within the wrapping for the hamburger to protect it from vertical forces.
The various embodiments of the invention may be combined.
For example, in Figure 11 the composite packaging consists of a 206790~
pleated zone 26 similar to zone 13 in the previous embodiments, a first straight or unpleated zone 25 similar to zone 15 in Figure 8, and a second straight, unpleated zone 27 similar to zone 18 in Figure 9.
Importantly, the packaging described herein requires less paper. For example, the embodiment of Figure 1 requires 25~
less paper than a fully pleated packaging. Moreover, this configuration further results in substantial savings in manufacturing since pleating of the straight zone is not required.
Figure 12 shows yet another embodiment of the invention wherein a wrapper is formed of a zone 32 without pleats and a zone 33 with pleats, said two zones 32, 33 having the same width 8. The pleats of zone 33 are fixed by fixation bands 31 made, for example, of paper. The bands are glued, or affixed by other similar means to both the first and the back faces of the pleated and the unpleated zones. Preferably, the bands 31 are folded back to form longitudinal unpleated zones 34. The edges of the pleats, which may be sharp, are thus protected by bands 31. This embodiment is easy to manufacture in a continuous strip.
As another embodiment of the invention in Figure 13, a double wrapping is shown including a pleated sheet 70 with fixation bands 72 and a strip 74 disposed in the central region of sheet 70. Strip 74 may consist, for example, of a band of paper coated on the top surface 76 with aluminum foil.
Preferably, the strip 74 is secured to a straight sheet and then -- 2~67904 both sheets are pleated simultaneously. For example, if the top surface 78 of sheet 70 and the bottom surface of strip 74 are plastic coated then the two components can be easily welded by application of heat.
S The strip 74 makes the wrapping resistant to stains, for example from sauces if the wrapping is used for a hamburger.
Moreover, the strip also acts as a thermal barrier to maintain the central region of the wrapped article warm. Usually this central region of the wrapped article is warmer than its top or bottom. If strip 74 is made slightly thicker than sheet 70, it reinforces the sheet 70 against creasing and protect the wrapped article in the vertical or transversal direction. An advantage of this latter embodiment is that when the double wrapping is discarded it does not create more voluminous refuse than a single-ply wrapping.
As shown in Figure 14, the double wrapping may be formed by providing a first roll of paper 80 having a top surface 82 coated with polyethylene, and a second roll of paper 84 coated on the bottom surface with polyethylene, and coated on top surface 88 with aluminum foil. The two strips from the two rolls are positioned in contact with each other by a pressure roller 92 and then welded together by using a sealing roller 94. Thereafter the joined strips are pleated to result in a pleated product 96.
Product 96 is then cut to size as at 98.
In the Figures all the pleated regions zones are shown as being formed of parallel, symmetrical pleats. Of course, it should be understood that other types of pleats may be used.
It should be understood that in all these embodiments due to the semi-rigid nature of the material of the packaging, once the pleated zone 1 is fully extended by opening the central portions of the pleats, as shown in Figures 3, 6 and 10, the pleated zone 1 retains its extended shape.
Numerous modifications may be made to this invention without departing from its scope as defined in the appended claims.

DETAILED DESCRIPTION OF THE INVENTION
Referring now to Figure 1, a packaging constructed in accordance with this invention is generally a flat relatively thin sheet composed of two zones 1 and 13. Zone 13 is generally rectangular and is formed by taking a sheet of paper, or other material, and folding it to form sequential pleats. Zone 13 has a width 8 which in this embodiment is smaller than the dimension 4 of zone 1. Zone 1 is unpleated, or straight and is joined adhesively or by other means to zone 13.
In a preferred embodiment of the invention, the packaging consists of a layer of paper coated with a plastic material such as polyethylene. Thus, zone 1 includes an upper layer or face 15 of polyethylene and lower layer or face 30 of paper.
In the embodiment of Figure 1, zone 1 is attached by using an adhesive, or any other similar means, to the border section 14 20679~
of zone 13, wherein the polyethylene layer lS of zone 1 contacts the paper layer 16 of zone 13.
The dimensions 3 and 4 of zone 1 are selected so that zone 1 can at least partially cover the object to be wrapped. For S example, Figure 2 shows a generally cylindrical object which may be sandwich such as a hamburger 31, having a generally round top with a diameter 10. Hamburger 31 is wrapped by first positioning the packaging so that zone 1 is disposed peripherally around the hamburger 31 with the polyethylene layer contacting the hamburger. The zone 1 is then folded over the hamburger top 31 and bottom (not shown). The wrapping is completed by pulling on the zone 13 longitudinally so that the pleats open at their central region disposed adjacent to the side of the hamburger and training zone 13 around the hamburger until the hamburger is totally enclosed. The closed regions of the pleat form the top 12 of the wrapping, except for circular opening 11. At opening 11, the hamburger may be covered by the edges of zone 1.
It was found that the packaging shown in Figure 1 can be used easier and faster then a packaging formed of a completely pleated material. Moreover it is easier for the customer to hold the hamburger using the straight, unpleated zone 1.
The embodiment of Figure 4 is similar to the previous embodiment but it is made up of a single sheet composed of a pleated zone 13 and a straight zone 9. In this embodiment, the two zones 9, 13 have widths 7, 8 respectively which are substantially the same. As discussed in U.S. Patent No.
4,795,648, a pleated packaging is made from a sheet folded to make pleats 13. The pleats are secured by two fixation bands, A
and B or other securing means. Advantageously, the embodiment of Figure 4 can be made by first making a pleated sheet and then opening the pleats before fixation bands A, B are applied.
Alternatively, the packaging may be made from a single sheet by not forming the pleats in zone 9 at all. The packaging of Figure 4 may have, for example, an overall length and width in the range of 5.86"-6.25". The pleated zone 13 may consist of about 10-12 pleats, each pleat being formed by two sheet folds having a width of 0.58" and 0.39" respectively.
The embodiment of Figure 4 is particularly suited for wrapping relatively flat, semicircular objects, such as a taco.
As shown in Figure 4, a taco 6 is first placed on the top half of zone 9. Zone 9 is formed so that its length exceeds the length 5 of the taco 6. The whole packaging is then folded over to partially cover the taco, as seen in Figure 5. Preferably the width 7,8 of the packaging is smaller than the width of the taco.
In the configuration of Figure 5, a portion of the taco thus extends above the packaging. The taco is then finally wrapped by pulling longitudinally on zone 13 as indicated in Figure 5 by arrow L and then training zone 13 around the taco 6 and zone 9 as indicated by arrow M. The final closed wrapping is shown in Figure 6.
The packaging of Figures 4-6 has the same advantages as the wrapping of Figures 1-3, except that it is more suitable for tacos. More specifically, a customer can easily remove the zone 13 and use the remaining zone 9 to hold the taco during eating.
In the embodiment of Figures 7 and 8, zones 13, 1' are adhesively secured along border 17 with the polyethylene layer 15 facing the polyethylene layer 13' of zone 13. Before an object is wrapped in this packaging, the two zones are unfolded as shown in Figure 8. The object is then placed on zone 1' and zone 13 is then wrapped around the object as in the previous embodiment.
The embodiment of Figures 9 and 10 is composed of a pleated zone 13 and a straight, unpleated zone 18 which may be secured to zone 13 in a manner similar to zone 15 in Figures 7, 8. While pleated zone 13 is made of a relatively thin film which is easily pleated, zone I8 is made of stiffer material, such as cardboard coated with a plastic material. The width 19 of zone 18 is selected to correspond to the height of the object to be wrapped.
Moreover, while zone 13 expands in its central region in length while it is being opened, the length of zone 18 remains the same.
Thus prior to wrapping, the zone 18 is longer than zone 13. As shown in Figure 10, the packaging of Figure 9 is wrapped around a hamburger 24 so that zone 18 is disposed peripherally around the side of the hamburger. In this manner zone 18 forms a protective wall within the wrapping for the hamburger to protect it from vertical forces.
The various embodiments of the invention may be combined.
For example, in Figure 11 the composite packaging consists of a 206790~
pleated zone 26 similar to zone 13 in the previous embodiments, a first straight or unpleated zone 25 similar to zone 15 in Figure 8, and a second straight, unpleated zone 27 similar to zone 18 in Figure 9.
Importantly, the packaging described herein requires less paper. For example, the embodiment of Figure 1 requires 25~
less paper than a fully pleated packaging. Moreover, this configuration further results in substantial savings in manufacturing since pleating of the straight zone is not required.
Figure 12 shows yet another embodiment of the invention wherein a wrapper is formed of a zone 32 without pleats and a zone 33 with pleats, said two zones 32, 33 having the same width 8. The pleats of zone 33 are fixed by fixation bands 31 made, for example, of paper. The bands are glued, or affixed by other similar means to both the first and the back faces of the pleated and the unpleated zones. Preferably, the bands 31 are folded back to form longitudinal unpleated zones 34. The edges of the pleats, which may be sharp, are thus protected by bands 31. This embodiment is easy to manufacture in a continuous strip.
As another embodiment of the invention in Figure 13, a double wrapping is shown including a pleated sheet 70 with fixation bands 72 and a strip 74 disposed in the central region of sheet 70. Strip 74 may consist, for example, of a band of paper coated on the top surface 76 with aluminum foil.
Preferably, the strip 74 is secured to a straight sheet and then -- 2~67904 both sheets are pleated simultaneously. For example, if the top surface 78 of sheet 70 and the bottom surface of strip 74 are plastic coated then the two components can be easily welded by application of heat.
S The strip 74 makes the wrapping resistant to stains, for example from sauces if the wrapping is used for a hamburger.
Moreover, the strip also acts as a thermal barrier to maintain the central region of the wrapped article warm. Usually this central region of the wrapped article is warmer than its top or bottom. If strip 74 is made slightly thicker than sheet 70, it reinforces the sheet 70 against creasing and protect the wrapped article in the vertical or transversal direction. An advantage of this latter embodiment is that when the double wrapping is discarded it does not create more voluminous refuse than a single-ply wrapping.
As shown in Figure 14, the double wrapping may be formed by providing a first roll of paper 80 having a top surface 82 coated with polyethylene, and a second roll of paper 84 coated on the bottom surface with polyethylene, and coated on top surface 88 with aluminum foil. The two strips from the two rolls are positioned in contact with each other by a pressure roller 92 and then welded together by using a sealing roller 94. Thereafter the joined strips are pleated to result in a pleated product 96.
Product 96 is then cut to size as at 98.
In the Figures all the pleated regions zones are shown as being formed of parallel, symmetrical pleats. Of course, it should be understood that other types of pleats may be used.
It should be understood that in all these embodiments due to the semi-rigid nature of the material of the packaging, once the pleated zone 1 is fully extended by opening the central portions of the pleats, as shown in Figures 3, 6 and 10, the pleated zone 1 retains its extended shape.
Numerous modifications may be made to this invention without departing from its scope as defined in the appended claims.
