Abstract

PROBLEM TO BE SOLVED: To provide a packaging bag for sandwich with which the package of a sandwich can be easily opened with one hand and the sandwich can be eaten quickly.SOLUTION: The sandwich S is packaged with an outer packaging member 1 from the outside and, in order to prevent the migration of a water content or an oil content in ingredients I, a boundary member 2 is inserted between a bread P and the ingredients. Further, an opening portion 11 for opening an envelope when eating the sandwich S is disposed in the outer packaging member 1 and a crease portion 21 is formed on the boundary member 2 by doubling the neighborhood of the center in the longitudinal direction. Therein, when the ingredients I are held between upper and lower parts by the boundary member 2, the crease portion 21 is protruded outward from the outer edge of the bread P, and when the sandwich is packed with the outer packaging member 1, the crease portion is located in the same direction as the opening portion of an outer packaging portion, and thereby, not only the opening portion can be easily opened with one hand but also the boundary member can be quickly drawn out just after the opening.

Description

  The present invention relates to a sandwich packaging bag for packaging a sandwich sandwiched with raw vegetables and meat sold at, for example, a convenience store.

  Traditionally, sandwiches sold at convenience stores and supermarket stores are sandwiched directly with bread. Therefore, immediately after the tool is sandwiched between the bread, the moisture and oil content of the tool starts to move to the bread. Therefore, by the time the purchaser purchases the sandwich, the bread absorbs the moisture and oil content of the ingredients, so that the original texture and flavor of the bread are impaired.

  By the way, a bread package with ingredients (for example, refer to Patent Document 1) including a separate member that separates bread and ingredients so that the moisture of the ingredients does not penetrate into the bread when heated in a microwave oven is proposed. ing. In this bread package with ingredients, a part of the exterior member and a part of the separate member are fixed, and the separate member can be removed when the exterior member is separated into two.

JP 2004-83079 A

  However, in the conventional bread package with ingredients as described above, for example, it is difficult to use a seasoning containing a mixture of raw vegetables and oils that easily get moisture. That is, when the exterior member is pulled to the left and right, the separate member is also pulled out at the same time, so that raw vegetables and seasonings that easily adhere to the separate member are likely to jump out of the bread. Furthermore, in order to prevent these ingredients from popping out, the exterior member must be carefully separated so as to slowly pull out the separating member, which not only takes time but also holds the bread by hand. And the sandwich itself loses its shape.

  As the shape of the sandwich, for example, there are not only a triangular or rectangular shape having a cut surface that is easy to stand alone, but also a thick and difficult to stand by utilizing the original shape of bread. Such sandwiches that do not stand up easily become expensive when packed and sold in containers such as boxes and packs, so they are sold in cheap bags such as polystyrene. However, such sandwiches are easy to lose shape and hard to eat without tableware. On the other hand, even with tableware, it takes time to change the sandwich.

  SUMMARY OF THE INVENTION Accordingly, a first object of the present invention is to provide a sandwich packaging bag that can be easily opened with one hand and can be eaten quickly. The second object is to provide a sandwich packaging bag that can be sold while maintaining the original freshness and texture of the sandwich. A third object is to provide a sandwich packaging bag capable of continuously holding a sandwich in an easy-to-eat state even without tableware.

  In order to solve the above-mentioned problems, the sandwich packaging bag according to the present invention has a portion that can be easily opened with one hand when eating a sandwich, and a boundary is provided so that the sandwich tool does not directly contact the bread. It is possible to remove this boundary quickly before meals.

  That is, the present invention relates to a sandwich packaging bag made of a thermoplastic resin for packaging a sandwich composed of a bread and a tool sandwiched between the bread, an outer packaging member for wrapping the sandwich from the outside, and between the bread and the tool. And a boundary member to be inserted. The outer packaging member has an opening portion that is opened when the sandwich is eaten. The boundary member has a fold portion formed by folding in half in the longitudinal direction from the vicinity of the center, and when the boundary member sandwiches the tool from above and below, the fold portion protrudes outward from the outer edge of the bread. Yes. When the outer packaging member wraps the sandwich, the fold portion of the boundary member is positioned in the same direction as the opening portion of the outer packaging portion.

  By the way, since the tool sandwiched between the sandwiches contains moisture and oil, the tool may stick if the moisture or oil is adsorbed on the surface of the boundary member. This is thought to be due to the surface tension of the moisture and oil content of the tool. Therefore, it is desirable that the boundary member is embossed at least on the surface in contact with the tool. Thereby, the surface tension which a tool brings to a boundary member can be reduced, and this tool can make it difficult to stick to a boundary member.

  Also, when eating sandwiches that are packed in bags, it takes time to take them out of the bags and put them on tableware, so you can see the scene of eating while sliding the sandwiches from the opened part of the bag. However, in this way of eating, when eating or drinking other side dishes or drinks, it is difficult to eat because the rest of the sandwich (eat) must be returned to the bag and placed on a table or desk. Therefore, the outer packaging member is provided with a self-supporting portion that can stand on its own side with the sandwich placed on the side facing the opening portion. Accordingly, the self-supporting portion can support the load of the sandwich and hold the outer packaging member in a self-supporting state.

  Here, “bread” is not limited to bread, coppe bread, roll bread, rye bread, French bread, croissant, focaccia, and bagel, but tortilla, crepe skin, and galette made of thin dough.

  "Ingredients" include, for example, raw vegetables such as tomatoes, cucumbers and lettuce, warm vegetables, fruits, eggs, cheese, ham, cutlet, roasted bees, kebabs, teriyaki chicken, chicken roast, bacon, hamburger, winner, sausage, Tuna, salmon and other seafood or processed products thereof, and those mixed with sauces and dressings, or combinations thereof are applicable.

  The “sandwich” is not limited to vegetable sandwiches and ham sandwiches sandwiched between raw vegetables and ham, but includes hamburgers, hot dogs, paninis, tacos, and crepes.

  The “thermoplastic resin” corresponds to a biodegradable resin such as polystyrene, polypropylene, polyethylene terephthalate, or polylactic acid resin.

  The “outer wrapping member” corresponds to, for example, a pillow wrapping formed by using a rectangular film as a raw material in a plan view and bonding ends of the film. The outer packaging member is preferably provided with side gussets that are valley-folded on both sides.

  The “boundary member” corresponds to, for example, not only a rectangular film in a plan view but also a degreased paper and a cooking sheet. The shape of the “boundary member” is not limited to a quadrangle, but may be a triangle, a diamond, or a cylinder. These boundary members may be singular or plural. The “film” is not limited to a non-processed surface, but may be a mat-processed or embossed one. Furthermore, it is more desirable to perform mat processing and embossing on at least the surface in contact with the tool.

  “Opening portion opened when eating the sandwich” means an opening for eating the sandwich, and is not limited to the cut provided at the end of the outer packaging member, for example, the circumference of the outer packaging member Perforations, cutting bands, and tear tapes provided in

  The “folded portion formed by folding in half in the longitudinal direction from the vicinity of the center” means a portion that is picked with a finger to pull out the boundary member immediately before eating the sandwich after opening the opening portion. “The fold portion protrudes outward from the outer edge of the pan” means a state in which the boundary member can be smoothly pulled out without touching the pan when the boundary member sandwiches the tool.

  “The fold portion of the boundary member is positioned in the same direction as the opening portion of the outer packaging member” means that the fold portion is fingered without sliding the sandwich from the outer packaging member in a state where the opening portion is opened. It means the position that can be picked.

  “Embossing” corresponds to, for example, a process of attaching special ink to a surface in contact with a tool of the boundary member or a process of pressing the back surface. The shape of “embossing” corresponds to, for example, a rectangular or circular dot shape, zigzag shape, wave shape, and grid shape. Furthermore, the “embossing” may be singular or plural, and may be provided in either the same direction or a direction orthogonal to the direction in which the boundary member is pulled out.

  The “side facing the opening” means, for example, the right side when the opening portion is provided on the left side of the outer packaging member, and the lower side when provided on the upper side. The “self-supporting portion” is not limited to, for example, a double-folded end portion of the outer packaging member, and corresponds to a member in which a fixing member is separately provided outside or inside the outer packaging member.

  In the sandwich packaging bag according to the present invention, when the outer packaging member wraps the sandwich, the fold portion of the boundary member is positioned in the same direction as the opening portion of the outer packaging member, so that the opening portion can be easily opened with one hand. Immediately after this, the boundary member can be removed without any trouble. That is, by performing the work of opening the opening part and the work of pulling out the boundary member separately, it becomes difficult for ingredients such as raw vegetables containing moisture or soft seasonings to stick out of the bread, and the sandwich is used as an outer packaging member. It can be eaten quickly by picking the crease and pulling out the boundary member without breaking the shape. Thus, even if the meal time is short, the purchaser can easily eat the sandwich without getting his hands dirty. Furthermore, by providing a boundary between the bread and the utensil with the boundary member, it is possible to enjoy not only the moisture and oil content of the utensil but also the flavor to the bread, so that the original hardness and taste of the bread can be enjoyed.

    Moreover, the embossing is given to the surface which contacts the tool of a boundary member, The surface tension which a tool brings to a boundary member can be reduced, and this tool can make it difficult to stick to a boundary member. That is, according to the present invention, the total area where the boundary member and the tool come into contact with each other can be reduced, and the surface tension can be reduced by allowing moisture and oil contained in the tool to escape into the embossed recess.

  Furthermore, the outer packaging member is provided with a self-supporting portion that can stand on its side facing the unsealing portion, so that the self-supporting portion supports the load of the sandwich so that the outer packaging member becomes self-supporting. Can hold. Therefore, it is possible to save the trouble of laying the bag between meals and to smoothly eat the sandwich.

The thin solid line indicates the fold of the side gusset of the sandwich packaging bag.

  FIG. 1 shows a sandwich packaging bag in which a sandwich is packaged as viewed from the front. As shown in FIG. 1, a sandwich packaging bag made of a thermoplastic resin according to the present invention includes an outer packaging member 1 that wraps a sandwich S from the outside, and a mated boundary member 2 that is inserted between a bread P and a tool I. And. The outer wrapping member 1 has an opening portion 11 made of perforations that are opened when the sandwich S is eaten. The boundary member 2 has a fold portion 21 formed by folding it in the longitudinal direction from the vicinity of the center. When the boundary member sandwiches the tool I from above and below, the fold portion protrudes outward from the outer edge of the pan P. To do. And when the outer side packaging member 1 wraps the sandwich S, the fold part 21 of the boundary member 2 is located in the same direction as the opening part 11 of this outer side packaging member 1.

  FIG. 2 shows the sandwich packaging bag shown in FIG. 1 as viewed from the right side. As shown in FIG. 2, when the sandwich S is packed in the pillow-type outer packaging member 1 formed by bonding the end portions of a rectangular thin film in plan view, the central portion swells to form a streamlined shape as a whole. . Moreover, the outer side packaging member 1 has a side gusset, and this side gusset spreads and the side surface is depressed.

  FIG. 3 shows the flow from the rectangular thin film F-1 to the formation of the pillow-type outer packaging member 1. As shown in FIG. 3 (A), when the mountain folds f1, f1 and the valley fold part f2 of the rectangular thin film F-1 are folded left and right respectively, and the adhesive margins f3 on both side parts and the lower end part are pasted, As shown in (B), the pillow-type outer packaging member 1 can be formed. This outer packaging member has side gussets 12 formed on the left and right mountain folds f1, f1 shown in FIG. Moreover, the upper end part of the thin film F-1 is not sticking, and the outer side packaging member 1 has the opening part 13 in this step. In addition, although the dimension of the outer side packaging member 1 is 16 cm wide, 23 cm long, and the side gusset width 7 cm, it is not limited to this. Although not shown, the thin film F-1 is provided with an opening portion in advance. This unsealing part may be provided either in a direction perpendicular to or parallel to the opening 13. When the opening portion is provided in a direction orthogonal to the opening portion 13, the outer packaging member 1 is provided near either the left or right side gusset 12, and when the opening portion is provided in a direction parallel to the opening portion, the upper end of the outer packaging member Provide near the bottom or bottom.

  FIG. 4 shows the flow from creating the sandwich S to packing it into the outer packaging member 1. First, as shown in FIG. 4A, a rectangular thin film F-2 having a width of 10 cm and a length of 30 cm is folded in half in the longitudinal direction from the vicinity of the center to form a boundary member 2. Hold from the top and bottom. Next, as shown in FIG. 4 (B), a tool sandwiched between the boundary members is sandwiched from above and below by a pan P to create a sandwich. Then, as shown in FIG. 4C, the sandwich S is in a state in which the fold portion 21 of the boundary member 2 projects outward from the outer edge of the pan P. Thereafter, as shown in FIG. 4D, the sandwich S is put in and wrapped while the side gusset is expanded from the opening 13 of the outer packaging member 1. In this case, the fold portion 21 of the boundary member 2 is positioned in the same direction as the opening portion 11 of the outer packaging member. After that, the opening 13 is closed by winding a surplus portion and fastening it with a tape, or cutting and crimping the surplus portion.

  FIG. 5 shows a flow from opening a sandwich sold at a convenience store to starting eating. First, as shown in FIG. 5A, the sandwich S is packaged by the outer packaging member 1. Here, the purchaser opens the opening portion 11 with the other hand while holding the right portion of the sandwich S wrapped with the outer packaging member 1 with one hand. Then, as shown to FIG. 5 (B), a part of sandwich S and the crease | fold part 21 of the boundary member 2 are exposed. If the crease 21 is further picked with fingers of the empty hand and then pulled leftward, the sandwich S as shown in FIG. 5 (C) can be eaten.

  As described above, when the outer packaging member 1 wraps the sandwich S, the fold portion 21 of the boundary member 2 is positioned in the same direction as the opening portion 11 of the outer packaging member, so that the opening portion can be easily performed with one hand. Immediately after opening, the boundary member can be removed without any trouble. That is, by separately performing the operation of opening the unsealing portion 11 and the operation of pulling out the boundary member 2, it becomes difficult for ingredients I such as raw vegetables containing moisture or soft seasonings to jump outside the bread P, and sandwich S Can be eaten quickly by picking the fold 21 and pulling out the boundary member 2 without breaking the shape of the outer packaging member 2. Thus, even if the meal time is short, the purchaser can easily eat the sandwich without getting his hands dirty. For example, while holding sandwich S with one hand, seasonings such as dressing and liquid sauce can be poured into ingredient I according to taste, so people on diet, those who want to think about nutritional balance, and those who like light taste It will be easy to eat. Further, by providing a boundary between the bread P and the ingredient I with the boundary member 2, in order to prevent not only the moisture and oil content of the ingredient I but also the flavor from being transferred to the bread, for example, enjoy the original hardness and taste of French bread be able to.

  Next, another boundary member inserted between the sandwich bread and the utensil will be described with reference to FIGS. The parts or parts equivalent to those shown in FIGS. 1 to 5 are numbered by adding a uniform 100 in FIG. 6 for the sake of easy reference and the like (hereinafter the same applies to FIGS. 7 to 9). , And a uniform number of 200 to 500.)

  FIG. 6 shows a sandwich in which a tool is sandwiched from above and below by a boundary member whose entire surface is subjected to dot-type embossing. As shown in FIG. 6, the surface of the boundary member 102 that is in contact with the tool is embossed, thereby reducing the surface tension that the tool I brings to the boundary member and making it difficult for the tool to stick to the boundary member. be able to. That is, the total area of contact between the boundary member 102 and the tool I can be reduced and the surface tension can be reduced by releasing the moisture and oil content W of the tool into the embossed recess 122. Therefore, for example, even if there is a tomato with a lot of water, a cucumber sliced in a flat shape, and a teriyaki chicken entwined with a viscous sauce, it is difficult to stick to the boundary member 102, and the purchaser can smoothly apply this boundary member. Can be extracted from the sandwich S

  FIG. 7 shows a state in which boundary members are respectively inserted into a plurality of separate tools. As shown in FIG. 7A, the boundary members 202 and 202 can be sandwiched from above and below with respect to the two tools I-1 and I-2, respectively. Further, as shown in FIG. 7B, a new boundary member 302 in which another boundary member is added between the two folded boundary members is used and is added between the tools I-1 and I-2. A boundary member can be inserted. These not only prevent moisture and oil from the ingredients I-1 and I-2 from transferring to the bread P, but also prevent contact between the ingredients I-1 and I-2, and the texture of each ingredient. And enjoy the taste. The boundary member folded in half and the added boundary member may be bonded and bonded with an adhesive or the like.

  FIG. 8 shows a state where a cylindrical boundary member is inserted into the cylindrical sandwich. As shown in FIG. 8, a cylindrical sandwich can be formed by winding the tool I with a cylindrical boundary member 402 and further winding a bread P thereon.

  Next, a sandwich packaging bag having a self-supporting portion will be described with reference to FIG. FIG. 9 shows a state in which the sandwich is self-supporting with the outer packaging member placed. As shown in FIG. 9, a self-standing portion 512 that can stand on its own with the sandwich S placed is provided on the side of the outer packaging member 501 that faces the opening portion 511. When the sandwich S is packed in the outer exterior member 501, the central portion swells, so that the whole becomes a streamline shape. Moreover, since the outer side packaging member 501 has a side gusset, the side gusset spreads and the side surface is recessed inward. Accordingly, the self-supporting portion 512 serves as a leg. Furthermore, the self-supporting portion 512 is obtained by double-folding the end portion of the outer packaging member 501 facing the opening portion 511. Since the strength is higher than the outer edge of the opening portion, it does not fall down with the sandwich S inserted. Can stand on its own. Therefore, it is possible to save the trouble of laying the bag between meals and to smoothly eat the sandwich. That is, while holding the sandwich S with the outer packaging member 501 with one hand, the self-supporting portion 512 can be placed on the table and the sandwich can be gripped from the side again through the outer packaging member when eating. You can eat smoothly while eating and drinking side dishes and drinks. The height may be shortened by scooping or cutting the outer edge of the extra outer packaging member 1 according to the length of the sandwich.

  The sandwich packaging bag according to the present invention is not limited to sandwiches that sandwich the ingredients in bread, but can be widely used in industries related to rice balls and hand-rolled sushi that sandwich or squeeze the ingredients.
