Description

[Technical field]

[0001] The present invention relates to a bag having a main storage section for enclosing foodstuffs such as fresh produce and a secondary storage section for enclosing printed sheets such as instructions, the main storage section having a gusset section for enclosing foodstuffs and a tear-off tape section for easily removing only the printed sheets such as instructions stored in the secondary storage section. [Background technology]

[0002] Generally, fresh produce and the like are sold in bags, or the bags are used for carrying the sold products home. For example, ingredients for cooking are purchased separately and then put into a bag to take home. Therefore, when cooking this dish, it is common practice in households to purchase a variety of ingredients individually and prepare a separate recipe for cooking.

[0003] Furthermore, to avoid the hassle of purchasing many different types of ingredients individually, it is common to sell a set amount of ingredients in a bag in order to efficiently provide only the amount of ingredients needed by the people. In contrast to this, in addition to bags having one storage section for one item to be stored, bags having two storage sections in one bag have also been used. For example, Japanese Patent Application Laid-Open No. 2005-145536 (Patent Document 1) discloses a method of forming a second bag portion by further folding back a bottom portion of a bag body made of sheet material on both sides.

[0004] Furthermore, there is a package disclosed in JP-A-2002-337887 (Patent Document 2) in which a plurality of layers of sheet material are formed into a multi-layer structure and sealed at arbitrary locations to form a continuous package of multiple layers. There is also a packaging body shown in JP 2013-107678 A (Patent Document 3) which has a product storage section and a label storage section, and after the product to be packaged is stored in each product storage section, the final seal margins of the same outer edges are attached to each other to simultaneously seal each label storage section and each product storage section.

[0005] Other structures for opening a sealed bag include those disclosed in Utility Model Registration No. 3065443 (Patent Document 4), Japanese Patent Laid-Open No. 2002-145283 (Patent Document 5), and Japanese Patent Laid-Open No. 2005-87023 (Patent Document 6), in which an opening tape is arranged parallel to the opening of the bag, i.e., across the width of the bag, and an opening is created in the indicated direction by tearing the film using this tape. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP2005-145536A [Patent Document 2] Patent Publication No. 2002-337887 [Patent Document 3] Patent Publication No. 2013-107678 [Patent Document 4] Utility model registration No. 3065443 [Patent Document 5] Patent Publication No. 2002-145283 [Patent Document 6] Patent Publication No. 2005-87023 Summary of the Invention [Problem to be solved by the invention]

[0007] For example, if the bag contains ingredients necessary to make a dish for a specific number of people and further includes information about the ingredients, details of the ingredients, or recipes printed with instructions and methods for cooking with the ingredients, the bag will be extremely convenient to use. To address this issue, for example, when packaging such ingredients in a bag, it is possible to enclose a piece of paper listing the type of ingredient or a sheet with a recipe printed on it together with the ingredient. However, in this case, the ingredient and the printing ink will come into direct contact with each other, and if the printing sheet is made of paper, the paper itself will become wet with the moisture from the ingredient, making it difficult to use.

[0008] It is therefore necessary to store such food information and recipes, for example made of paper, in a safe and easy-to-use format. In this case, it is possible to enclose each of them separately by using the above-mentioned Patent Document 1, Patent Document 2, or Patent Document 3, which has a configuration in which one bag body has two storage sections. However, in Patent Document 1, since the bag portion 2 is simply provided, the stored print sheet is likely to shift obliquely, resulting in an unattractive appearance. Furthermore, if a printed sheet having the same width as the sub-storage section is used, it will be difficult to store it, and the operation will require a great deal of effort. For example, when it comes to selling food ingredients, they are inevitably used in a moist environment, and even if food ingredient information or recipes made of paper or the like are inserted, they will inevitably get wet, which not only makes the product look dirty but also causes major hygiene problems such as the growth of bacteria.

[0009] Next, Patent Document 2 relates to a manufacturing method and a bag for constructing a multi-layer structure using multiple types of films, and is not intended for sealing contents individually between each layer. Therefore, although it has a plurality of storage sections, it is not used as a bag body for storing different contents in each storage section as required at a time after the bag is made. Furthermore, with regard to Patent Document 3, the fact that it has a product storage section and a label storage section means that it can be used to store ingredients and recipes, but the final seal margins of the same outer edges are attached to each other to simultaneously seal each label storage section and each product storage section, which means that ingredients, recipes, etc. must all be sealed when the bag is made.

[0010] That is, the final seal portions of the same outer edges are stuck together and simultaneously sealed to form a bag. Therefore, it cannot be used as a bag in which ingredients are sealed in the main storage section as needed after the bag is made, and necessary information, recipes, etc. are further sealed in the sub-storage section. The sub-storage section must also be configured to be able to store sheets on which information, recipes, etc. to be stored are printed in a predetermined location. Furthermore, it is necessary to have a main storage section for enclosing ingredients and a secondary storage section for storing sheets with recipes and other information printed on them, so that the contents can be sealed inside while also allowing the secondary storage section to be opened separately to take out the necessary recipes, etc.

[0011] The use of tape to tear a portion of the bag as this removal mechanism is shown in Patent Documents 4 to 6. However, these are tapes for opening the bag itself, i.e., the main storage section as referred to in this application, and are used as tapes for opening the entire width of the bag by arranging the tape in the same width direction as the original opening of the bag in order to efficiently open the bag itself. In response to this, it is necessary to open only the sub-storage section without opening the main storage section, and to arrange the tape in such a configuration that the stored print sheets can be easily removed. For these reasons, it is desirable to provide a bag that can solve these problems. [Means for solving the problem]

[0012] The invention according to claim 1 is a bag having a main storage section with an opening formed by a front sheet and a back sheet, the bag has side gussets with gussets on both sides, and a secondary storage section sheet on the outer surface of the front sheet of the bag, and the front sheet and the secondary storage section sheet The bag body 1 is sealed on both sides, A sub-storage section is formed in which a print sheet is inserted between the sheets, and the sub-storage section includes At a position inside the sealed positions on both sides of the bag body, The present invention comprises a bag body having a restricting seal portion that restricts the position of the printed sheet to be inserted, and thus can solve the above-mentioned problems.

[0013] In addition, in the invention according to claim 2, the restricting seal portion is formed of a bag body that restricts the positions of both side edges of the printed sheet to be inserted, and the above-mentioned problem can also be solved by this invention. Furthermore, the invention of claim 3 may be a bag having such a configuration in which the auxiliary storage section sheet has a tape portion for cutting the auxiliary storage section sheet so that items stored in the auxiliary storage section can be removed, and a handle portion formed by cutting a part of the auxiliary storage section sheet for holding the tape portion is provided. Furthermore, in the invention according to claim 4, the tape portion provided in the auxiliary storage portion may be a bag disposed from the opening of the auxiliary storage portion sheet toward the bottom, and may have such a configuration. Effect of the Invention

[0014] As configured as described above, the invention of claim 1 makes it possible to provide a bag body capable of storing bulky items such as fresh produce required for cooking in the main storage section, and capable of storing a printed sheet on which cooking methods, etc. are printed in the secondary storage section. In particular, the restricting seal portion restricts the insertion position of the printing sheet into the sub-storage portion so that the sheet can be stored in an attractive manner, and the width of the printing sheet can be freely selected, so that the placement position can be restricted.

[0015] This also makes it possible to regulate the position of the print sheet during insertion in an optimal manner according to its shape and size. Furthermore, when a bulky item is stored in the main storage section, the shape of the bag will be deformed depending on the item inserted. However, even in this case, not only can the position of the printed sheet inserted into the secondary storage section be properly regulated, but the position of the printed sheet after insertion can also be regulated to a predetermined position.

[0016] Next, according to the invention of claim 2, the position of both sides of the printed sheet to be inserted can be regulated by the regulating seal portion, so that the insertion of the printed sheet can be regulated from both sides, and the printed sheet can be guided to the desired position in a good-looking manner. Furthermore, it is possible to regulate the position as desired according to the size and shape of the print sheet.

[0017] According to the invention as defined in claim 3, the sub-storage section has a tape section for tearing, so that only the printed sheets stored in the sub-storage section can be easily taken out. In particular, since the auxiliary storage section itself has a tape section, the printed sheet in the auxiliary storage section can be easily removed while the main storage section remains closed, so that advance preparations for cooking can be made using the recipe on the printed sheet before removing the fresh produce. Furthermore, the tape portion can be easily pinched by the tab to tear the sub-storage sheet.

[0018] Next, according to the invention of claim 4, the tape portion can be arranged from the opening of the auxiliary storage section toward the bottom, and this tape portion can cut the auxiliary storage section sheet with the linear portion extending from the opening of each bag body toward the bottom, making it easy to remove the printed sheet. [Brief description of the drawings]

[Figure 4] FIG. 1 is a diagram showing the sheet material of each roll of resin sheet when making a bag body according to the present invention. [Diagram 5] FIG. 2 is a diagram showing an example of a state in which the bag body according to the present invention shown in FIG. 1 is used; [Figure 6] FIG. 1 is a diagram showing another example of a bag body according to the present invention. [Figure 7] FIG. 1 is a diagram showing another example of a bag body according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The configuration shown in Figure 1 is a bag 1 according to the present invention, which has an opening into which food ingredients and the like can be inserted into a main storage section and has a side gusset section 12, and further has a secondary storage section in addition to the main storage section, and the secondary storage section can be used to insert a printed sheet such as an instruction manual. A bag having side gusset portions 12 has gusset portions on both sides of the bag, and these gusset portions on both sides are side gusset portions 12.

[0021] Therefore, since it has gussets on both sides, the opening width of the bag 1 can be made wider by the width of the gussets, resulting in a bag that can enclose a large amount of food needed to cook for a number of people according to the recipe on the printed sheet. Therefore, the main storage section has a large storage capacity because it has a gusset portion that is the side gusset portion 12, and can store a wide variety of ingredients, etc. It is also possible to store bulky foods such as various salads.

[0022] The main storage section having such a side gusset portion 12 further has a sub-storage section as another storage section. In the configuration shown in the figure, the main storage section is made up of front and back sheets 10 and 11, which are made of front and back sheet material, and an auxiliary storage section sheet 20, which is made of a single sheet of auxiliary storage section sheet material, is layered on top of these sheets. Both side edges of this auxiliary storage section sheet 20 and the lower end in Figure 1 are heat sealed to form an auxiliary storage section between the main storage section and the main storage section. Therefore, the outer sheet 10 made of outer sheet material and the auxiliary storage sheet 20 form the auxiliary storage section.

[0023] Furthermore, the bottom of the bag body 1 is a square base body, and the bag body is formed so that it can stand up. Therefore, basically, it is a bag body 1 having a main storage section with a side gusset section 12 consisting of a back sheet 11 made of back sheet fabric and a front sheet 10, and further has a secondary storage section consisting of the surface of the front sheet 10 and the secondary storage section sheet 20. That is, the bag has two storage sections: a main storage section with a wide opening and a side gusset section 20 made of a back sheet 11 and a front sheet 10, and a secondary storage section made of the front sheet 10 and a secondary storage section sheet 20.

[0024] In this case, there are no particular gussets on either side of the secondary storage section, so that, for example, thin sheets or the like can be stored in the secondary storage section. For example, printed sheets are inserted into this sub-storage section. A printed sheet is a sheet on which the product name, product description, advertisement, recipe, etc. are printed and displayed, and is made of paper, resin film, resin sheet, etc., and is not limited to being made up of a single sheet but may be made up of multiple sheets. Furthermore, for example, seasonings and the like may be enclosed in thin packages and stored in the secondary storage section.

[0025] Furthermore, the auxiliary storage sheet 20 has a slit 21 at the center of the upper opening side. This is a cutout to make it easier to store in the secondary storage section. Further, the auxiliary storage sheet 20 has a tape portion 3 adhered to its side from the opening toward the bottom. This tape portion 3 is a tape portion for cutting and tearing the sub-storage portion sheet 20. Furthermore, the tape portion 3 has a gripping portion 4 formed by cutting a part of the auxiliary storage portion sheet 20 at an arbitrary position, and the tape portion 3 can be gripped from this portion and the auxiliary storage portion sheet 20 can be torn.

[0026] The sub-storage section sheet 20 of the sub-storage section can be torn by cutting with this tape section 3, and the printed sheet in this sub-storage section can be taken out. Furthermore, the auxiliary storage section sheet 20 has regulating seal portions 5 formed on both side edges thereof. For example, when inserting a printed sheet such as a recipe into the sub-storage section, the regulating seal section 5 is formed to regulate the insertion position of the printed sheet and insert it into a specified position, and the printed sheet can be inserted along the sealing processing position of the regulating seal section 5.

[0027] This regulating seal portion 5 refers to a seal processing portion formed by fusing, welding or gluing the front sheet 10 and the auxiliary storage section sheet 20, which are formed in a predetermined position in advance. For example, the regulating seal portion 5 is formed at a predetermined location to determine the storage position of the auxiliary storage section in which the inserted printed sheet is stored, and to store the printed sheet in a good-looking manner at the predetermined position. Therefore, by inserting the print sheet along this regulating seal portion 5, the print sheet can be neatly inserted into the specified position.

[0028] For example, by providing a regulating seal portion 5 that determines the width direction of the opening of the sub-storage portion, a print sheet can be inserted from a predetermined position. In this case, it is not limited to forming the entire outer periphery of the insertion position of the printing sheet to be stored with a regulating seal portion 5 to regulate the directional position of insertion, but it is also possible to provide a regulating seal portion 5 only in a part of it to specify only the insertion position of the printing sheet. Any regulating sheet portion 5 may be used as long as it can identify the insertion position of the print sheet and facilitates insertion.

[0029] Furthermore, the lower part of the bag has a sub-storage bottom seal part 22 which forms the bottom of the sub-storage part. Thus, it forms a base for the printed sheets stored in the sub-storage section. Incidentally, even if the auxiliary storage section bottom seal section 22 is not particularly provided, the bottom position of the print sheets stored therein may be restricted by the restricting seal section 5. Next, even if a printed sheet, such as paper material carrying information on recipes or ingredients, is placed in the secondary storage section, it is separated from the items stored in the main storage section, and even if ingredients containing moisture are placed in the secondary storage section, the printed sheet can be stored without getting wet.

[0030] This not only prevents the printed sheets of recipes and the like from getting dirty, but also prevents them from coming into contact with the outside, preventing the growth of bacteria and the like within the secondary storage section, meaning that they can be stored hygienically and safely. Furthermore, since it is separated from the food in the main storage section, the ink on the printing sheet will not come into contact with the food, and the food can be stored hygienically. In addition, the bag is basically formed by sealing each side edge, and the strength of the seals allows it to stand upright even when foodstuffs are stored inside. The bottom of this bag body is an upright rectangular base body having a rectangular bottom.

[0031] FIG. 2 is an end view taken along line AA in FIG. As shown in this figure, the bag body of the present invention consists of a back sheet 11 and a front sheet 10, and has a side gusset portion 12 consisting of an approximately V-shaped gusset portion on the side, and is further formed by overlapping and aligning a secondary storage section sheet 20 on the front sheet 10. Further, the bags are formed by welding, fusion or adhesion through a sealing process. The back sheet 11 and the front sheet 10 form a main storage section, and the front sheet 10 is overlaid with a sub-storage section sheet 20, which forms the sub-storage section in this portion.

[0032] In addition, the front sheet 10 and the sub-storage section sheet 20 are sealed together to form a regulating seal section 5, which allows the insertion position of the printed sheet to be specified. Furthermore, the print sheets can be guided to a predetermined storage position, and the storage position of the stored print sheets can be regulated. The auxiliary storage section sheet 20 has a tape portion 3, and by tearing this portion the auxiliary storage section sheet 20 can be broken, and the auxiliary storage section can be opened.

[0033] FIG. 3 shows the bottom of the bag, with one side of the bag being sealed between the back sheet 11 and the side gusset portion 12, and the other side being sealed between the side gusset portion 12, the front sheet 10 and the secondary storage sheet 20. The bottom is then sealed to form a bag having a rectangular bottom. Further, in the lower direction of the bag body, there is a sub-storage section bottom seal portion 22 which forms the bottom of the sub-storage section. This allows the bottom to be positioned appropriately when storing thin items such as paper materials, resin sheets or films, such as printed sheets containing recipes or information on ingredients, in the sub-storage section.

[0034] FIG. 4 is a diagram showing an example of each sheet material when forming the bag according to the present invention using three rolls of resin sheets. First, the sheet material formed using the first roll of resin sheet is used as the secondary storage section sheet material to form the secondary storage section sheet 20. That is, the sheet material unwound from the roll is pulled onto the bag making machine for use as the secondary storage sheet material.

[0035] Furthermore, the sheet material formed by using the second roll of resin sheet is used as the resin sheet material forming the front sheet material, the back sheet material, and further a side gusset portion between the two. Therefore, by forming a folded portion exactly in the middle, the front sheet 10, the back sheet 11 and the side gusset portion 12 corresponding to one gusset portion between them are formed, and this portion is formed by forming a folded portion in the sheet fabric on the bag making machine and feeding it.

[0036] Furthermore, a third roll of resin sheet is used to produce a sheet material for forming a side gusset portion 12 corresponding to the other gusset portion. Therefore, the central portion is folded and the sheet material is run on a bag making machine to form a side gusset portion 12 which corresponds to the other gusset portion. Thus, the first roll is a roll having one width, the second roll is a roll that is at least twice as wide as that width, and the third roll is a roll of a slightly shorter width.

[0037] In particular, a roll of a resin sheet having an appropriate width may be used depending on the folding depth of the side gusset portion that forms the gusset portion. Therefore, by appropriately determining the width of the fold, a bag of the desired size, i.e., a bag having a gusset, can be manufactured. For example, with regard to the opening that forms the main storage section, bags of any shape can be manufactured, from bags having a rectangular opening with a wide front and back surface and a narrow gusset width, to bags having an opening that is even more square-shaped, or even bags that go beyond this and have a rectangular opening with a longer gusset portion compared to the length of the front and back surfaces, i.e., a longer width.

[0038] Furthermore, the tape portion 3 is arranged on the bag making machine, and then the side edges and bottom are sealed, and at an appropriate point in time, the regulating seal portion 5 or the auxiliary storage portion bottom seal portion 22, etc. are formed. Further, proper cutting is performed on the bag making machine. For example, the bag body may be appropriately cut in the direction of the opening, or the slits 21 in the sub-storage sheet 20 may be formed.

[0039] FIG. 5 is a diagram showing an example of a state in which ingredients are placed in the main storage section of the bag 1 according to the present invention and a printed sheet such as a recipe is placed in the sub-storage section, with the opening of the bag 1 rolled up and sealed. In this case, the front and back faces of the opening are brought together and folded or rolled in the direction of the back sheet 11 to close the opening. In this case, the secondary storage section into which the printed sheet is inserted is positioned on the front side, and the printed sheet containing necessary visual data, etc. together with information on ingredients and recipes stored in this secondary storage section can be displayed visible from the outside.

[0040] For example, photo data of presentation examples, product information data, etc. may be displayed on the surface. Recipes and the like may also be folded and stored. When the product is traded in this state, the printed sheet stored in the sub-storage section can be taken out by cutting the sub-storage section sheet 20 with the tape section 3. This allows customers to prepare meals in advance by checking the product information and recipes on the printed sheets.

[0041] Furthermore, when removing the printed sheet, the tape portion 3 is pinched by the tab 4 and the tape portion 3 is used to cut and tear the sub-storage portion sheet 20, thereby opening the sub-storage portion and removing the printed sheet from inside. In this case, the main storage compartment remains closed while the necessary information on ingredients, recipes, etc. can be taken out using the printed sheet. Although the auxiliary storage bottom seal portion 22 is not shown in the figure, it may be provided as required.

[0042] FIG. 6 is a diagram showing an example in which the restricting seal portion 5 for restricting the position when the print sheet is inserted is formed as a narrow band-like restricting seal portion 5 only on one side portion. In this way, the recess can be formed at any position or in any shape, and is not limited to being formed on both sides, but may be formed on only one side. In addition, while the drawing shows an example in which the electrodes are long and narrow, the electrodes are not limited to this shape, length, position, or number. Any number of the electrodes may be formed at any position and in any shape.

[0043] It is sufficient that the device at least specifies the insertion position of the printed sheet to be stored in the auxiliary storage section, or regulates the insertion direction or insertion state, etc., and that the device forms the regulating seal portion 5 for this purpose. Therefore, any desired regulating seal portion 5 may be formed depending on the size, position, etc. of the print sheet to be inserted.

[0044] FIG. 7 shows a regulating seal portion 5 formed in a circular shape instead of a narrower band-like regulating seal portion 5, and other regulating seal portions such as dot-like regulating seal portions or circular regulating seal portions formed by dots, etc. may also be formed. In addition, the regulating seal portion 5 may be in the form of a wavy line or a broken line. As shown in the figure, any number of regulating seal portions 5 of any shape may be formed at any position.

[0045] It is sufficient that the seal portion 5 is used as the restricting seal portion 5 for restricting the insertion position and the insertion state of the printed sheet to be stored in the auxiliary storage portion. In addition, in this figure, the auxiliary storage section bottom seal portion 22 is not limited to a band-shaped seal portion shape, but other shapes such as dot shapes, point shapes, line shapes, wavy line shapes, dashed line shapes, and any other shapes may be used. Furthermore, the sub-storage section bottom seal portion 22 may be replaced by a regulating seal portion 5 of any shape at the bottom. Alternatively, the secondary storage section bottom seal portion 22 may not be provided. [Explanation of symbols]
