Description

  This invention is a combination of various shapes used to store household items, foods, etc. in a general household as well as when used to store purchased products at supermarkets and drug stores, for example. It relates to resin bags.

  Conventionally, in the supermarket, drug store, mass retailer, etc., the storage method in the product storage bag after purchasing the product is that the purchaser puts the product in the store's basket and brings it to the accounting counter, and the accounting operator calculates Put the later product in a separate bag, and finally put a product storage bag that is the size and number of synthetic resin bags that match the quantity of the purchased product in this bag. A system has been adopted in which a bag is moved to a bagging work table in another position, and the product purchased in the product storage bag is taken and taken home.

  By the way, when you put the purchased product in the product storage bag yourself, if the purchased product is wet or wet, frozen food, raw food, scented food, etc., it does not stain or smell other products In order to do so, after a product is stored in a thin synthetic resin bag (auxiliary bag) such as polyethylene, it is further put in a product storage bag.

  For this reason, synthetic resin bags are placed on or near the supermarkets, drug stores, mass retailers, etc., and the buyer can take out the synthetic resin bags freely, Can be stored.

  The product storage bag used for the above-mentioned purposes is provided with a folded portion on both side edges of a flat and thin synthetic resin tube, one end of this tube being a bottom portion by a widthwise seal portion, and the other end being a mouth portion. In addition, it has a structure in which a hand is provided on both sides of the other end serving as a mouth portion.

  Since such a product storage bag has gussets on both sides, there is an advantage that when the product storage bag is opened, the product is greatly spread by the gussets and the product can be stored easily.

  Further, the synthetic resin bag has a flat and thin synthetic resin tube, a widthwise seal portion that forms a bottom portion, and a perforation for cutting that is close to and parallel to the seal portion at a constant interval in the length direction. A structure in which a synthetic resin bag is formed between a seal portion and a perforation at a distance from each other, and a synthetic resin bag in which a large number are continuous via the seal portion and the perforation is wound into a roll body It has become.

  Such a synthetic resin bag is arranged by attaching the roll body to a dedicated support member so that the roll body can be rotated, and a person who wants to store a product picks the synthetic resin bag located at the forefront of the roll body with a fingertip. By pulling out and separating from the perforated part, an independent synthetic resin bag is formed, and the product is stored in the synthetic resin bag.

  In the above synthetic resin bag, one end of a flat cylindrical body portion is a bottom portion by a seal, and the other end that is a pick side for pulling out in a roll body is a cutting edge along a perforation, and this cutting edge is thin Since the two synthetic resin sheets are in close contact with each other, the overlapping synthetic resin sheets are peeled off to form a mouth portion for putting a product.

  Since the product storage bag and the synthetic resin bag as described above are both folded flat, the thin synthetic resin sheet is in close contact with each other at the mouth. It is necessary to open the mouth by peeling off the synthetic resin sheet that is in close contact.

  However, when opening the mouth part where two thin synthetic resin sheets are in close contact, the fingertip and the synthetic resin sheet have good sliding properties, so it is difficult to simply open the mouth part by holding the synthetic resin bag with the fingertip. is there.

  When opening the mouth of such a synthetic resin bag or the product storage bag described above, if the fingertips are moistened with water, the slipperiness between the fingertips and the synthetic resin sheet is suppressed, and two synthetic resin sheets that are in close contact are formed. It is known that the mouth can be easily opened by taking the effort to shift the phases of the two synthetic resin sheets with the fingertips picked up.

  For this reason, sponges and wet towels with water in the vicinity of the synthetic resin bags are placed on the bagging work tables of supermarkets, drug stores, mass retailers, etc. Before opening the mouth portion of the storage bag, the fingertip is touched with a sponge or wet towel to moisten it, and the mouth portion of the synthetic resin bag is opened with the wet fingertip.

  However, sponges and wet towels that have been soaked in water become hotbeds for the propagation of various bacteria due to their humidity and comfortable room temperature, and are extremely unsanitary because they are used one after another by many unspecified people, especially sponges and wet towels. When contaminated with bacteria, there is a danger that it adheres to the fingertip and leads to the spread of bacteria.

  For this reason, it is necessary to regularly replace sponges and wet towels with clean ones, but personnel must be secured for replacement and cleaning, so extra costs must be accounted for replacement. I must.

  In addition, sponges and wet towels give an unpleasant feeling after being touched by an unspecified number of people, so avoid touching them, inevitably many people choose to lick their fingertips, and unsanitary situations occur. ing.

  Therefore, the present invention can easily open the mouth part by only smashing a part of the bag with the fingertip or tearing it outward without wetting the fingertip with water. An object of the present invention is to provide a synthetic resin bag that can eliminate the use of towels.

  In order to solve the problems as described above, the invention of claim 1 is provided with a fold or crease folded between the sheets on both side edges of the two-layered synthetic resin sheet, and one end of the two synthetic resin sheets. In the synthetic resin bag having the bottom as the seal and the other end as the mouth, at a position near the mouth of the synthetic resin bag, at least a portion where both the synthetic resin sheets overlap with the gusset is surrounded by perforations, The structure which provided the destructible part which can be torn with a fingertip is employ | adopted.

  Here, the synthetic resin bag uses a long synthetic resin tube made of flattened polyethylene or the like, and is provided with a folded portion between the sheets on both side edges of a thin synthetic resin sheet that is in a two-ply contact state. The perforation is formed in, for example, a horizontal semicircular shape or a U-shape, and the destructible part surrounded by the perforation is large enough to fit the fingertip.

  The invention according to claim 2 is a composite in which a two-layered synthetic resin sheet is provided on both side edges with a folded portion between the sheets, one end of each of the synthetic resin sheets is sealed to be a bottom portion, and the other end is a mouth portion. In the resin bag, at a position near the mouth of the synthetic resin bag, at least a portion where both the synthetic resin sheets overlap with the gusset portion is surrounded by a cut that is partly cut, and a destructible portion that can be broken by a fingertip The provided configuration is adopted.

  According to a third aspect of the present invention, the perforations or cuts that form the breakable part are provided in a frame shape that is separated from both ends, and the perforations or cuts are both bordered by the inner folding edge of the town part. A configuration is employed in which the synthetic resin sheet is provided so as to straddle the directly overlapping portion and the overlapping portion of both the synthetic resin sheets and the town portion.

  According to a fourth aspect of the present invention, the perforations or cuts that form the breakable part are formed in a frame shape that is separated from both ends, and the perforations or cuts are close to the inner folding edge of the town part. The structure provided in the part which a synthetic resin sheet and a town part overlap is employ | adopted.

  The invention according to claim 5 employs a configuration in which the synthetic resin bag is provided with a hand on both sides of the other end serving as a mouth portion.

  Here, in the synthetic resin bag, in order to clearly display the existence of the destructible portion, display marks are provided on the destructible portion and the periphery thereof, or a colored line or the like is provided on the sheet to reach the periphery of the destructible portion. In addition, if characters and designs such as “poke”, “pull”, and “break” are printed on the breakable part and its surrounding position, the procedure for opening the breakable part is easy to understand. Become.

  When the above-mentioned synthetic resin bag has a handle, a stacked state of a large number of sheets becomes a package, and when there is no handle, it can be a continuous bag wound in a roll shape. A long synthetic resin tube with gussets on both side edges is provided with a heat seal part at the bottom and cutting perforations parallel to and adjacent to the heat sealing part at regular intervals. It becomes a mouth part, and it becomes a single synthetic resin bag by pulling out the synthetic resin bag from the roll body and cutting it with a perforation for cutting.

  According to the present invention, in the synthetic resin bag provided with the folds folded on both side edges, at a position near the mouth of the synthetic resin bag, at least a portion where both the synthetic resin sheets overlap with the gusset is formed by perforations or cuts. Since it is surrounded and provided with a destructible part that can be torn by fingertips, if you break the destructible part by pushing it with your fingertip or pulling it outward while holding the synthetic resin bag with your hand, There is no restriction part for outward movement, and the town part is overlapped, so the destructible part located in this town part is more resistant than the destructible part of one synthetic resin sheet, For this reason, by the operation of tearing the destructible part of the synthetic resin sheet located on the outside with the fingertip, the inner side of the gusset part moves with respect to the two synthetic resin sheets, and between the two synthetic resin sheets By the movement of the gusset portion, opens between two sheets of synthetic resin sheet, whereby the mouth portion can be opened easily with a finger tip, you need to wet the fingertip with water to open the mouth is eliminated.

  Also, when opening the mouth of the plastic bag, it is no longer necessary to moisten the fingertips with water, so a sponge or wet towel soaked in water is placed on the bagging work table in supermarkets, drug stores, mass retailers, etc. Complete removal of wet sponges and towels that are no longer needed and easily get dirty can completely eliminate hygiene problems caused by dirty sponges and wet towels, and install and manage wet sponges and wet towels It is possible to reduce the cost required for the store, and to improve the cleanliness of the store.

  Furthermore, when the synthetic resin tube of the synthetic resin bag is easy to tear in the length direction, if the breakable part is formed by a pair of cuts or a combination of a pair of cuts and perforations, When the U-shaped part of the material synthetic resin tube has an angle with respect to the length direction, it is possible to eliminate the separation part involved in the generation of the tear, and when this is done, the destructible part is pushed by the fingertip and opened. It is possible to effectively prevent the occurrence of tears in both synthetic resin sheets, and the outer peripheral edge of the tongue piece generated when the destructible portion is opened becomes smooth, so that the appearance can be improved.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A synthetic resin bag 1 according to the first embodiment shown in FIGS. 1 and 2 is formed by flattening two synthetic resin sheets 2a and 2b using a thermoplastic synthetic resin such as polyethylene, and both sheets 2a and 2b. 2 is provided with a fold portion 3 (pleats or folds) folded between both sheets 2a and 2b, and one end of both synthetic resin sheets 2a and 2b is provided with a heat seal 4 together with the gusset portion 3 at the bottom. 5, the other end is a mouth portion 6, and a hand 7 is provided on both sides of the other end to be the mouth portion 6, and at least both the synthetic resin sheets are positioned near the mouth portion 6 of the synthetic resin bag 1. A destructible part 9 surrounded by a perforation 8 and capable of being broken by a fingertip is provided in a portion where 2a, 2b and the town part 3 overlap.

  The synthetic resin bag 1 uses a synthetic resin tube, and the tube is flattened so as to become two synthetic resin sheets 2a and 2b and a gusset portion 3 folded at both side edges between the two synthetic resin sheets 2a and 2b. The heat seal 4 in the width direction forming the bottom portion 5 is applied to one end of both the synthetic resin sheets 2a and 2b, and the other end side which becomes the mouth portion 6 is provided with a hand 7 on both sides, and the center of the mouth portion 6 is provided. It has a cutting shape in which a tongue piece 10 for knotting or tape application is provided at a position.

  The perforations 8 forming the breakable portion 9 are formed in a frame shape that is separated from both ends, for example, in a horizontal semicircular shape or a U-shape, and both ends of the perforations 8 are for tearing prevention. The breakable portion 9 surrounded by the perforation 8 is sized so that the fingertip can be accommodated. In the example of FIG. The inner bent edge 3a is used as a boundary, and the synthetic resin sheets 2a and 2b are provided so as to straddle the overlapping portion and the overlapping portions of the synthetic resin sheets 2a and 2b and the town portion 3.

  Accordingly, the perforation 8 is integrally formed by punching over a portion where the two synthetic resin sheets 2a, 2b directly overlap and a portion of the four sheets where the two synthetic resin sheets 2a, 2b and the town portion 3 overlap. .

  The perforation 8 of the example shown in FIG. 2 is provided in the position where the both synthetic resin sheets 2a, 2b and the town part 3 overlap in the vicinity of the inner bent edge 3a of the town part 3, and the perforation 8 is substantially For example, the four sheets are integrally formed by punching.

  By forming the breakable portion 9 with a portion where the two synthetic resin sheets 2a, 2b directly overlap each other and a perforation 8 penetrating through the overlapping portion between the two synthetic resin sheets 2a, 2b and the town portion 3. When the breakable part 9 is broken, the direction of the front and back of the synthetic resin bag 1 is lost, and the arrangement of the synthetic resin bag 1 is not limited.

  The breakable portion 9 formed by the perforation 8 is sized to fit a fingertip, and in the illustrated case, the perforation 8 has a horizontal semicircular shape, and the both ends thereof are separated from the synthetic resin bag 1. However, the perforation 8 is not limited as long as it can pierce the breakable portion 9 with a fingertip or torn outside, and the shape of the perforation 8 and the orientation of the perforation 8 Can be selected arbitrarily, and a destructible portion 9 with a perforation 8 is provided only at a portion where one side of the synthetic resin bag 1 is overlapped with the synthetic resin sheets 2a, 2b and the town portion 3. May be.

  Such a synthetic resin bag 1 according to the first embodiment generally has a package shape in which a large number of sheets are stacked one upon another.

  Next, the synthetic resin bag 1 according to the second embodiment shown in FIG. 3 is a synthetic resin bag (auxiliary bag) without a handle, and a thin synthetic resin tube is used. The heat seal 4 in the width direction is flattened so as to be the resin sheet 2a, 2b and the gusset part 3 folded at both side edges between the two synthetic resin sheets 2a, 2b, and forms a bottom part 5 at one end of both synthetic resin sheets 2a, 2b. The other end side is a straight mouth portion 6, and at a position near the mouth portion 6 of the synthetic resin bag 1, at least both synthetic resin sheets 2 a and 2 b and the town portion 3 on both sides or one side. As in the first embodiment, a destructible portion 9 that is surrounded by the perforation 8 and can be broken by a fingertip is provided in the overlapping portion.

  The synthetic resin bag 1 according to the second embodiment as described above can be a continuous bag wound in a roll shape, and this synthetic resin bag 1 is a long synthetic resin provided with gussets 3 on both side edges. The tube is provided with a heat seal 4 part which becomes the bottom part 5 and a cutting perforation parallel to and close to the tube at regular intervals corresponding to the length of the bag, and the cutting edge by the cutting perforation is at the cutting edge and the mouth part 6 Then, a single synthetic resin bag 1 is obtained by pulling out the continuous synthetic resin bag from the roll body and cutting it with a perforation for cutting.

  4 (a) and 4 (b) show that the breakable part 9 provided in the synthetic resin bag 1 shown in the first or second embodiment described above is used by using a cut or a mixture of cuts and perforations. A third embodiment formed is shown.

  First, the destructible portion 9 shown in FIG. 4A has a pair of vertically symmetric cuts 13, 13 partially divided by one or several cut-off portions 12. It is formed by applying to a frame shape that is separated at both ends such as a U-shape, and a small hole 11 for tearing is provided at the remote end of both cuts 13, 13. The destructible part 9 surrounded by is sized to fit the fingertip.

  Next, the breakable part 9 shown in FIG. 4 (b) uses a pair of cuts 13 and 13 and perforations 14 and 14 which become the separation part 12, and uses them in a horizontal semicircular or U-shape. A small hole 11 for preventing tearing is provided at both ends of the perforations 14, 14, and the cuts 13, 13 and the perforations 14, 14 The surrounded destructible portion 9 is large enough to fit a fingertip.

  Specifically, as shown in FIG. 4B, the pair of cuts 13 and 13 are applied so as to be curved in a horizontal semicircular shape or a U-shaped arc, and the perforations 14 and 14 are both cuts 13. , 13 is provided with a short length so as to extend from the remote end.

  4 (a) and 4 (b), the separation part 12 that divides the pair of cuts 13 and 13 is set at a short distance at the position of the top part of the side-shaped semicircular or U-shaped curve. When the synthetic resin bag 1 is not used or the breakable portion 9 is used without opening the breakable portion 9, the breakable portion 9 is released from both synthetic resin sheets 2a and 2b. It plays a role to prevent this.

  Here, when the destructible portion 9 is pushed and opened with a fingertip, it protrudes as a tongue piece to the outside of the synthetic resin bag 1, and at this time, the periphery of the tongue piece has a jagged shape. However, as shown in the third embodiment in FIGS. 4 (a) and 4 (b), when the breaks 13 and 13 are used to form the breakable portion 9, the tongue piece There is an advantage that the peripheral edge becomes a smooth shape and the appearance can be improved.

  Moreover, when the synthetic resin bag 1 is made using a synthetic resin tube as a raw material, depending on the material, both synthetic resin sheets 2a and 2b have a property of being easily split in the length direction of the synthetic resin tube. is there.

  In the case of the synthetic resin bag 1 made of such a material, when the breakable portion 9 is pushed open with a fingertip, the breakable portion 9 is formed only by the perforation 8 as in the first or second embodiment. Then, when the cut portion between the perforations 8 is cut, a tear may occur from the cut portion in both the synthetic resin sheets 2a and 2b.

  Since such a rift occurs along the length direction of the material synthetic resin tube, in order to prevent the generation of the rift, in the laterally semicircular or U-shaped perforation 8 that forms the breakable portion 9 The perforated separation part may be eliminated as much as possible from the part having an angle with respect to the length direction of the material synthetic resin tube in the horizontal semicircular shape or the U shape.

  Therefore, as shown in the third embodiment of FIGS. 4A and 4B, the breakable portion 9 is formed by a pair of cuts 13, 13, or a pair of cuts 13, 13 and a perforation 14. , 14 can be used together to eliminate the cut-off part involved in the generation of tears in the horizontal semicircular or U-shaped part that has an angle with respect to the length direction of the synthetic resin tube. Thus, it is possible to effectively prevent the tearing of both the synthetic resin sheets 2a and 2b when the destructible portion 9 is pushed open with a fingertip.

  In addition, when the breakable portion 9 is formed by a pair of cuts 13 or 13 or a combination of the pair of cuts 13 and 13 and the perforations 14 and 14, a tongue piece generated when the breakable portion 9 is opened. The outer peripheral edge of the lens becomes smooth, and the appearance can be improved.

  In any of the embodiments, in order to clearly display the existence of the destructible part 9, the destructible part 9 is surrounded by and surrounding the destructible part 9, and the destructible part 9 is instructed to break through. A display mark can be applied, or a colored line or the like can be applied to the synthetic resin sheets 2a and 2b so as to reach the periphery of the destructible portion 9, and a commercial can be displayed using the colored line.

  Further, if characters and designs such as “punch”, “pull”, and “break” are printed on the destructible portion 9 and its surrounding positions, the procedure for opening the destructible portion 9 can be easily understood.

  The synthetic resin bag of the present invention is configured as described above. For example, in the case of the synthetic resin bag 1 provided with the handle 7, the accounting operator puts it in the bag together with the product after the calculation and purchases it to the purchaser. The person moves with a bag to a bagging work table in another position, and is used in a system in which the purchased product is put in the synthetic resin bag 1 by himself.

  Further, when the synthetic resin bag 1 is a continuous bag wound in a roll shape, in a supermarket, a drug store, a mass retailer, etc., a holder or the like is used on the bagging work table or in the vicinity thereof. The roll-shaped synthetic resin bag 1 is arranged so as to be rotatable, and the purchaser freely pulls out the continuous synthetic resin bag and cuts it at the perforation for cutting, thereby cutting out a single synthetic resin bag 1. Allow the product to be stored.

  In order to open the mouth portion 6 in order to put the product in the synthetic resin bag 1, as shown in FIG. 5 (a), both sides near the mouth portion 6 of the synthetic resin bag 1 are held by hand, and both the thumb and forefinger are used. The destructible portions 9 of the synthetic resin sheets 2a and 2b are sandwiched from both sides, and in this state, the destructible portions 9 surrounded by the perforations 8 are placed between the synthetic resin sheets 2a and 2b as shown by arrows in FIG. Break through from one side to the other.

  In addition, also when the destructible part 9 is the synthetic resin bag 1 of one place, in order to open the opening part 6, in the state which hold | maintained the both sides near the opening part 6 of the synthetic resin bag 1 by hand similarly, Try to break through 9.

  As described above, the synthetic resin bag 1 is held by sandwiching the destructible portions 9 of both the synthetic resin sheets 2a and 2b from both sides with the thumb and forefinger. However, there is no restricting portion for the outward movement of the synthetic resin bag 1 on the inner bent edge 3a side of the town portion 3 located between the two synthetic resin sheets 2a and 2b.

  For this reason, when the destructible part 9 located in the town part 3 is pushed in the breaking direction by the fingertip, the destructible part located in the town part 3 by the town part 3 escaping outward on both sides of the synthetic resin sheets 2a and 2b. 9 is not torn. Therefore, the gusset part 3 has two synthetic resin sheets 2a on the inner folding edge 3a side by the action of breaking the breakable part 9 of the synthetic resin sheet 2a or 2b located on the outer side with a fingertip. 2b, and the town part 3 moves between the two synthetic resin sheets 2a and 2b. As shown in FIG. The gap between the synthetic resin sheets 2a and 2b is opened, whereby the mouth portion 6 can be easily opened with a fingertip, and the product may be stored in the synthetic resin bag 1 from the opened mouth portion 6.

  In this way, the mouth part 6 can be opened simply by pushing the fingertip and tearing the breakable part 9 surrounded by the perforations and cuts without getting the finger wet with water. The mouth portion 6 of the synthetic resin bag 1 can be opened, whereby the wet sponge and wet towel that have been used conventionally can be eliminated, and the cost of the store can be reduced and the cleanliness can be improved.
