Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handbag of a handbag, and more particularly to a handbag made of a synthetic resin which can withstand a large load.

[0002]

2. Description of the Related Art At present, handbags are consumed in large quantities, but many handbags are often discarded once used. For this type of handbag, a synthetic resin handbag is often used due to its strength. When the handbag is made of paper and the handbag is made of resin, it is desired that the handbag be removed from the handbag and discarded. Although it is rare, the work of removing the hand from the carrying bag is surprisingly complicated, and in fact, it is almost always discarded with the synthetic resin hand attached.
It has been pointed out that when a bag carrying a synthetic resin handbag is discarded and landed, the handbag is not disassembled for a long time, remains in the same shape, and exerts a large stress on nature.

[0003] Therefore, various attempts have been made to reduce the stress exerted on the natural world as much as possible by manufacturing this tie with a biodegradable synthetic resin. However, since this handle requires a certain strength, it is surprisingly used in a large amount and is thick, and unlike a film, it does not disassemble so that the prototype disappears in several tens of days after landfill, and it does not disassemble for several months. The biodegradation gradually progressed over 10 months from the beginning, and depending on the environment in which the land was buried, there was a case where almost no degradation could be visually confirmed even after several years.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned problems, and provides sufficient strength at the time of use. It is an object of the present invention to provide a handbag of a handbag that has less stress on the handbag.

[0005]

According to the present invention, in order to achieve the above object, a biodegradable synthetic resin-made hand main body 1 having a hollow portion 1a and formed in a tube shape is bent into an inverted U-shape.
Both lower ends of the main body 1 are applied to one side of a cardboard lip paper 2 to be glued to the mouth of the handbag 10, and two lower ends of the main body 1 are attached to one side of the lip paper 2. Is applied to the thin paper 2a which is sandwiched between the base paper 2 and the paper 2.

Therefore, the handle of the present handbag is formed in a tubular shape with the handle main body 1 having the hollow portion 1a. It exhibits an effect that the contact area is large and the biodegradation rate is increased even when the wall thickness is large.

[0007] Further, by forming the hand main body 1 in a tubular shape, appropriate elasticity suitable for gripping is obtained, and the rigidity is conversely reduced, and the mouth paper 2 is twisted by the hand main body 1 or the like. It has the effect of suppressing the tendency to deform three-dimensionally.

Further, according to the present invention, the lower end of the main body 1 is sandwiched and glued between the cardboard base paper 2 and the thin laminated paper 2a, so that the base paper 2 is thick and strong and does not deform. It has the function of maintaining a flat planar shape, and the thin laminated paper is freely deformed according to the peripheral surface of the gantry body having a circular cross-section, and the contact area becomes large. It has the effect of doing. The mouth paper 2 and the laminated paper 2a are integrated with the main body 1 so that they absorb moisture when buried and keep the humidity of the atmosphere of the main body 1 high to promote biodegradation. It shows.

Next, the handle of the handbag according to the second aspect of the present invention is to bend the biodegradable synthetic resin hand body 1 having a hollow portion 1a and formed in a tube shape into an inverted U-shape. Body 1
Are applied to one side of a cardboard lip paper 2 to be glued to the mouth of the handbag 10, and to the one side of the mouth paper 2, the both lower ends of the pallet body 1 are attached to the mouth paper 2. In this case, a technical means is adopted in which a laminated paper 2b also made of cardboard, which is sandwiched by the above, is glued with a heat-meltable glue material 4.

Therefore, according to the present invention, since the thin laminated paper 2a of the first aspect is changed to the thick laminated paper 2b, it is a matter of course that the mouth of the carrying bag 10 can be more strongly reinforced. , The main body 1 and a strong thick mouth paper 2,
Similarly, since it is sandwiched between the strong laminated paper 2b, the present invention has an effect of holding the main body 1 in a crushed state.

Further, when the thick paper 2b is used in the same manner as the thick mouth paper 2, the amount of water absorbed by the mouth paper 2 and the laminated paper 2b is increased by that much, and the promoting effect of biodegradation is more reliably achieved. It has the effect of transforming.

In the present invention, since a heat-meltable material is used for the glue material, the glue is heated and melted, and the glue material is radiated and hardened after the glue. Since strong adhesion and fixation can be achieved in a short time, the glue can be glued in a relatively short time while the main body 1 is crushed.

Next, according to the third aspect of the present invention, a biodegradable synthetic resin-made main body 1 having a hollow portion 1a and formed into a tube is bent into an inverted U-shape. Both lower ends are applied to one side of a cardboard mouth paper 2 to be glued to the mouth of the handbag 10, and the stapler needles 3, 3, 3,.
.. is fixed to the base paper 2 with a glue, and on one side of the base paper 2, a laminated paper 2a for holding both lower ends of the main body 1 with the base paper 2 is glued. We have taken measures.

Therefore, since the hand of the present carrying bag uses the stapler needles 3, 3, 3... And a function of securely fixing.

[0015]

Next, an embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, reference numeral 10 denotes a carrying bag. The bag 10 may be made of a known material such as paper, synthetic resin, or both. In the illustrated example, the handbag 10 has a front part 11, a rear part 12, a bottom part 13, and both side parts 14a, 14a.
b), a structure with a gore having an opening 15 in the upper portion is used. As the structure of the handbag 10, various types of conventionally known ones may be used.

In FIG. 1, reference numeral 1 denotes a main body of a hand, and reference numeral 2 denotes a mouth paper for sticking the main body of the hand 1 to the mouth of a handbag 10. The main body 1 is made of a biodegradable synthetic resin having a hollow portion 1a and formed in a tubular shape. The cross-sectional shape of the hollow portion 1a and the cross-sectional shape of the hand main body 1 may be appropriately selected as shown in FIGS. 4 to 6, and generally, both are circular and the cross-sectional shape is a ring shape (see FIG. 4). As shown in FIG. 5, if the cross-section of the main body 1 is formed into an oblong shape as shown in FIG. 5 or a rectangular shape as shown in FIG. Become. It is not necessary that both ends of the main body 1 reach the lower side of the base paper 2, and the lower end of the main body 1 ends a predetermined distance above the lower side as shown in FIG. It may be in the state of being.

As described above, when the cross section of the main body 1 is rectangular or oblong, the hollow portion 1a may have a similar shape to the cross section, but as shown in FIGS. A plurality of hollow portions 1b, 1b, 1b,... Having a small cross section may be provided side by side.

In the case where the main body 1 having a flat cross section is used, as shown in FIG. 10, when the same surface of the main body 1 is brought into contact with the mouth paper 2, The middle gripping portion is curved but close to a horizontal straight line, so that the carrying bag can be easily lowered. When the opposite surfaces of the main body 1 are brought into contact with the lip 2, the kinks are twisted and protrude more than the plane of the handbag 10,
When several sheets are piled up, they become bulky. However, when the same surface of the main body 1 of the hand is brought into contact with the mouth paper 2, the amount of protrusion is reduced, so that even if a large number of handbags 10 are piled up, it is possible to prevent bulkiness.

The main body 1 is bent in an inverted U-shape, and both lower ends of the main body 1 are applied to one side of a cardboard base paper 2 to be glued to the mouth of the handbag 10.
On one surface side of the mouth paper 2, a thin laminated paper 2 a sandwiching both lower ends of the main body 1 with the mouth paper 2 is glued. The mouth paper 2 is used for the purpose of holding the hand main body 1 and for the purpose of gluing the hand main body 1 to the handbag 10. First, the hand main body 1 folded in an inverted U-shape is used. The lower part is fixedly held. It is a simple method to use a glue material for this fixation, but the glue material has a weak adhesive force to the biodegradable synthetic resin-made main body 1 and cannot be securely fixed. Therefore, in the present invention, the thin overlap paper 2a which is easily deformed upon fixing is overlapped on the mouth paper 2, and the mouth body 2 is sandwiched between the mouth paper 2 and the overlap paper 2a. As shown in (2), the adhesive area of the glue material is increased (particularly, the thin laminated paper 2a is more closely contacted with the entire peripheral surface of the pallet main body 1 to increase the contact area), and is overlapped with the mouth paper 2. If the paper 2a is not peeled off, the main body 1 is prevented from falling off, so that the main body 1 is securely glued.

Therefore, the handbag of the present invention can firmly fix the handbag body 1 and can reliably hold the handbag 10 even when the biodegradable synthetic resin handbag body 1 having high rigidity is used.
The present invention can provide a durable handbag with excellent durability. Since the main body 1 has the hollow portions 1a and 1b, a large contact area with the natural world can be obtained, the biodegradable synthetic resin can effectively proceed, and the thick biodegradable synthetic resin can be obtained. It is possible to provide a handbag of a handbag that can be disassembled in a relatively short time even if the handbag body 1 made of steel is used.

In the present invention, the main body 1 made of the biodegradable synthetic resin, the mouth paper 2 and the laminated paper 2a are integrated. The laminated paper 2a has a hygroscopic property, and can provide a handbag of a handbag that keeps the buried atmosphere in a humid state in which biodegradation is actively performed.

Next, according to a second aspect of the present invention, the thin laminated paper 2a of the first aspect is changed to a thick laminated paper 2b. When the tubular main body 1 is sandwiched between the thick base paper 2 and the same thick laminated paper 2a and glued, the tubular main body 1 can be crushed to be in a flat state. Therefore, in the present invention, the mouth paper 2 and the overlap paper 2b are both made of thick paper.

However, in order to glue the tube-shaped main body 1 in a crushed state, it is necessary to continuously apply a pressing force until the glue material is solidified, which is disadvantageous for mass production.
Accordingly, in order to reduce this inconvenience to the extent possible, the present invention uses a glue material 4 for gluing the main body 1, the mouth paper 2 a and the laminated paper 2 b, which is heat-meltable.

In the present embodiment, the heat-meltable sizing material 4 is
As shown in FIG. 7, the heat-fusible adhesive material 4 is locally crushed in a planar manner, and is rapidly cooled and solidified. At the same time, as shown in FIG. 9, the crushed main body 1 is glued while being crushed.

Therefore, according to the present invention, the main body 1 can be flattened and firmly fixed, and the mouth paper 2 and the laminated paper 2b are both thick and strong, so that the main body 1 tries to return to a straight line. It is possible to provide a handle of a handbag that can prevent the mouth paper 2 and the like from being deformed from a planar state by a force to be applied.

Next, according to a third aspect of the present invention, in the configuration of the first or second aspect, both lower end portions of the main body 1 are connected to the handbag 1.
0 is attached to one side of the cardboard lip paper 2 to be glued to the lip of the cardboard 0, and is fixed to the lip paper 2 with the stapler needles 3, 3, 3,....

The stapler needles 3, 3, 3,...
The brim body 1 is straddled, its both ends penetrate the mouth paper 2, and the brim body 2 is bent on the opposite side when the brim body 1 is applied, and the stapler needles 3, 3, 3. At the time of gluing the main body 1, the main body 1 is configured to be crushed (actually, crushed into a flatter state than shown in FIG. 8). The stapler needles 3, 3, 3... Do not straddle the main body 1, but extend along the longitudinal direction of the main body 1 as shown in FIGS. The main body 1 may be penetrated and fixed. In the example of FIG. 8, both lower ends of the stapler needle 3 are bent inward, but as in the example of FIG. 11, both lower ends of the stapler needle 3 are bent inward, and the distal end is further bent. The stapler 3 may be bent to an appropriate shape so that the taper needle 3 does not stretch and come off in a general use by a binding machine.

In the present invention, the laminated paper 2a, 2b may be either a thick one or a thin one, and may be fixed by the stapler needles 3, 3, 3,. It can provide a handbag that can be firmly fixed.
