Description

  The present invention relates to a synthetic resin handbag that is suitably used as, for example, a garbage bag or a plastic bag.

  A flat bag having a square shape in front view and having an opening on one side has been used. After putting garbage inside, the opening was appropriately tied, and the tied part was carried by hand.

  However, in recent years, municipalities such as municipalities have started to charge for garbage (charges for garbage bags), and although there are differences between municipalities, there are litters on both sides in the width direction of the opening. A bag having the same structure as a plastic bag having a strip-like tongue piece (see Patent Document 1 below) has been used. This bag has a lateral gusset structure having gussets (gussets) on both sides in the width direction.

It is not clear why a bag with the same structure as a plastic bag has come to be used, but it is said that if there is a hand like a plastic bag it is easy to hold at the time of collection. In addition, a lateral gusset structure such as a plastic bag is advantageous in that the bag is satisfactorily provided, and a tongue piece is advantageous in that the mouth is easily tied.
Registered Utility Model No. 3110142

  Certainly, if a bag having the same structure as the shopping bag is used, the above-described advantages can be expected.

  However, there are only a pair of tongue pieces in the thickness direction of the bag, and the width of the tongue pieces is narrow. For this reason, when these tongue pieces are bound to each other, a gap is formed below the litter, and the contained dust may be exposed and spilled out. In fact, you often see garbage overflowing from the bag at the garbage collection site. Cleaning the garbage collection site is also difficult.

  In order to avoid such a situation, it is advisable to accommodate the trash with a margin, or to bundle the hands after binding the tongue pieces together.

  However, it is difficult to actually store garbage with a margin in a chargeable garbage bag. You can see your mouth full, not just closed, but even a broken bag. Further, when the hands are tied together, the advantages of the above-mentioned hands are lost, and the collecting work on the collecting side is particularly troublesome.

  As described above, the shopping bag has a shape having a hand on both sides in the width direction of the opening, and a thin strip-like tongue piece between the hands, and there is nothing else.

  Therefore, the main object of the present invention is to make it possible to easily close the opening and to fully enjoy the effects of having a hand.

  The means for this is a synthetic resin handbag having a lateral gusset structure having a hand on both sides in the width direction of the opening, and a pair of tongues facing each other in the thickness direction of the synthetic resin handbag. A synthetic resin handbag provided with a pair of tongue pieces facing each other in the width direction of the opening.

  In such a synthetic resin bag, if the pair of tongue pieces opposed in the thickness direction and the pair of tongue pieces opposed in the width direction are respectively bound, the opening can be closed without a gap. Moreover, the lender can be used as a lender.

  Of the tongue pieces, the tongue pieces opposed to each other in the width direction in the opening may be formed by a folded portion for forming the gusset. An integral tongue piece can be obtained easily and inexpensively. Moreover, since the tongue piece is integrated from the lower part of the litter, the strength is high and the gap when the opening is closed can be minimized.

  The tongue piece may be formed from the lower end portion of the handle or the vicinity thereof. More preferably, it should be formed from the lower end of the handle. The gap when the opening is closed can be eliminated more completely.

  Further, when the tongue piece has a wide portion on the base portion side in the length direction and a narrow portion on the tip side, and a step is formed between the wide portion and the narrow portion, the wide portion is Therefore, even when the accommodation amount is large, the generation of a gap can be suppressed. In addition, since the narrow part is not as sticky as the wide part, it is possible to easily bind the narrow part, and when the narrow part is bound, the wide part follows the narrow part and is pulled. Since the step portion blocks, the opening portion can be reliably closed by the wide portion.

  As described above, according to the present invention, since the opening can be closed by binding the tongue pieces in the thickness direction and the width direction, it is possible to prevent a gap from being formed below the lender. . For this reason, exposure and scattering of the contents can be prevented.

  Moreover, since two sets of tongue pieces having different directions also act to press the contents, it is possible to accommodate more contents.

  Moreover, even when the opening is tightly closed, the litter can be reliably used as a litter, so it is possible to ensure advantages such as convenience of carrying.

  As a result, when storing a product as a shopping bag, there is an advantage that the product is prevented from being exposed or popped out and can be easily carried. In addition, when used as a trash bag, a large amount of trash can be stored neatly, contributing to beautification of the trash collection location, etc., and convenience for both the trash collection side and the collection side. it can.

An embodiment for carrying out the invention will be described below with reference to the drawings.
FIG. 1 is a perspective view of a main part of a synthetic resin hand bag 11 (hereinafter referred to as “bag”) used as a garbage bag, a shopping bag, etc., and FIG. 2 is a partially broken perspective view of the bag 11 opened. FIG. 3 and FIG. 3 are front views of the bag 11.

  This bag is made of a suitable synthetic resin film such as polyethylene and has a lateral gusset structure having gussets (gussets) 12 on both the left and right sides in the width direction, and has a hand 21 on both sides in the width direction of the opening 13 at the upper end. The opening 13 has two sets of tongues 31 and 32.

  The said hand 21 is a strip | belt shape of an appropriate width | variety. Two sheets of front and back films folded in a V shape in the thickness direction of the bag 11 are welded to each other at the upper end 21a to form a closed loop.

  Of the two sets of tongue pieces 31, 32, one set of tongue pieces 31 oppose each other in the thickness direction of the bag 11, and the other set of tongue pieces 32 is the width direction of the opening 13. Are opposed to each other. Here, the former tongue piece is referred to as a first tongue piece 31, and the latter tongue piece is referred to as a second tongue piece 32. As shown in FIGS. 1 and 3, the first tongue piece 31 appears on the front surface, but the second tongue piece 32 is sandwiched between the first tongue pieces 31 while being folded in a V shape. It is. Hereinafter, the tongue pieces are expressed as a first tongue piece 31 and a second tongue piece 32 as necessary.

  The first tongue 31 piece is formed so as to extend upward from the vicinity of the lower end portion 21b of the handle 21 and includes a wide portion 31a on the length direction base portion side and a narrow portion 31b on the distal end side. There is a horizontal step 31c between 31a and the narrow portion 31b. The center lines of the wide portion 31a and the narrow portion 31b are coincident with each other and are formed in a so-called convex shape. Further, the space 14 between the lower end 21b of the litter 21 and the first tongue 31 is arcuate.

  Although the second tongue piece 32 is not completely the same shape as the first tongue piece 31, it has the same shape, and is formed to extend upward from the vicinity of the lower end portion 21 b of the handle 21, and has a longitudinal base portion. A wide portion 32a on the side and a narrow portion 32b on the tip side are provided, and a horizontal step 32c is provided between the wide portion 32a and the narrow portion 32b. The center lines of the wide portion 32a and the narrow portion 32b are coincident with each other and are formed in a so-called convex shape. Further, the space 15 between the lower end 21b of the handle 21 and the second tongue piece 32 is also arcuate (see FIG. 2).

  The bag 11 having such a structure is manufactured by fusing and cutting a tubular film 42 having folded portions 41 on both sides in the width direction as shown in FIG.

  Since the bag 11 has a structure having two sets of tongue pieces (the first tongue piece 31 and the second tongue piece 32) having the shape as described above, the depth of the left and right folded portions 41 of the tubular film 42 ( The tip 41a position of the folded portion 41 is set deeper than the position where both sides of the narrow portion 31b of the first tongue piece 31 are formed, as indicated by phantom lines in FIG. Although there may be a state in which the tips 41a of the folding portions 41 are in contact with each other, it is preferable in manufacturing that they are separated appropriately.

  At the same time as the bag 11 is cut straight in the width direction at an appropriate position of the tube-shaped film 42 to form the bottom 16 (see FIGS. 2 and 3) of the bag 11 at a portion separated downstream in the transport direction. A linear sealing portion 43 is formed on the upstream side in the transport direction (see FIG. 4B). Then, the portion having the sealing portion 43 is cut in a shape shown by a virtual line (cut line 44) in FIG. 4B, and an unnecessary portion 45 is removed.

  If it does in this way, the bag 11 which has the handle 21 and the two sets of tongue pieces 31 and 32 as mentioned above will be obtained. The opposing one side portions of the first tongue piece 31 and the second tongue piece 32 have a line-symmetric shape with the outer edge 42a (see FIG. 4) of the tube-shaped film 42 as an axis. The first tongue piece 31 and the second tongue piece 32 have the same shape even if not the same.

  The bag 11 opens the opening 13 and accommodates goods, garbage, etc., and then binds one of the two tongue pieces 31 and 32 to each other (31 or 32). The other tongue piece (32 or 31) is bound to each other and the opening 13 is closed. At this time, it is free to bind either the first tongue piece 31 or the second tongue piece 32 first.

  Since all the tongue pieces 31 and 32 are formed from the vicinity of the lower end 21b of the hand 21 as described above, there is no gap between the overlapping tongue pieces 31 and 32. Moreover, since the wide portions 31a and 32a on the base side in the length direction extend with a constant width toward the distal end direction, a large area for closing the opening portion 13 can be taken even when the amount of accommodation is large, and the opening is satisfactorily performed. The part 13 can be closed. Even in such a case, since the tongue pieces 31 and 32 have narrow portions 31b and 32b on the distal end side and step portions 31c and 32c between the wide portions 31a and 32a, the wide portions 31a. , 32a can be easily bundled and securely closed without contracting unnecessarily. For this reason, it is possible to prevent the contents from being exposed and popping out.

  And since the hand 21 has stood up in the both sides of the width direction in the state which closed the opening part 13, carrying around is convenient. In addition, since the bag 11 has a horizontal gusset structure, it is easy to sit on and the hand 21 can be kept standing, so that the hand 21 can be used even when the bag 11 is used as a garbage bag and placed in a garbage collection location. It can be easily held and can be easily collected.

  As described above, the bag 11 has an advantage that the product is prevented from being exposed or popped out when the product is stored as a shopping bag, and can be easily carried. Can be stored neatly, contributing to the beautification of the garbage collection site and the convenience of both the garbage collecting side and the collecting side.

  Hereinafter, another example of the shape of the bag 11 will be described. In this description, parts that are the same as or equivalent to the individual components described above are given the same reference numerals, and detailed descriptions thereof are omitted.

  The bag 11 shown in FIG. 5 has a shape in which the upper portion 21c of the handle 21 is pushed inward so as to be wider than the lower portion. Thus, when the upper part 21c of the hand 21 becomes wide, even when the heavy bag 11 is held, the biting of the hand 21 with respect to the hand can be suppressed and it can be easily held.

  The bag 11 shown in FIG. 6 is an example in which a gap is eliminated by forming a slit between the hand 21 and each tongue piece 31, 32, in other words, each tongue piece 31, 32 is provided at the lower end of the hand 21. The example formed from 21b is shown. If there is no gap in this way, the wide portions 31a and 32a at the lower ends of the tongue pieces 31 and 32 can be made the widest, so that the contents can be prevented from being exposed and popped out.

  The bag 11 shown in FIG. 7 is an example in which the upper portion 21c of the handle 21 is widened and the wide portions 31a and 32a at the lower ends of the tongue pieces 31 and 32 are widest. If it is such a bag 11, it can have the effect which each bag 11 shown in FIG. 5, FIG. 6 has, respectively. In addition, it is possible to reduce the portion to be excised during manufacturing.

  The bag 11 shown in FIG. 8 is also an example in which the upper portion of the handle 21 is widened, and the wide portions 31a and 32a at the lower ends of the tongue pieces 31 and 32 are widest. The shapes of 31 and 32 are inclined in a C shape so that the width gradually increases from the tip side to the base side. The bag 11 can also have the effects of the bags shown in FIGS. 5 and 6, and can reduce the number of parts to be cut off during manufacturing.

The above is one embodiment for carrying out the present invention, and the present invention is not limited to the above-described configuration, and other forms can be adopted.
For example, the second tongue piece may be configured separately and attached later.
