Description

[Detailed Description of the Invention] <Industrial field of application> The present invention relates to a bag body with a zipper in which a bite chuck is smoothly and easily opened / closed in a bag body having a male / female jaw type chuck in an opening. It is a thing.

<Prior Art> A synthetic resin bag having a male and female nail type chuck provided on the inner surface of the opening is generally used as a packaging bag for various articles.

<Problems to be solved by the invention> In the bag body as described above, when the chuck is occluded, the opening knob pieces on the smooth surfaces facing each other above the chuck are in close contact with each other. When you leave
It is very difficult to grip the knob part. Therefore, there is a drawback that the chuck cannot be opened and removed smoothly.

Therefore, in order to solve such a point, a bead is provided on the edge of the opening knob portion, or a bead is provided on the edge of the short knob portion by making the tab portion different in steps to prevent sticking of the knob portion. By doing so, a bag body is provided so that the gripping piece can be easily gripped by the fingers of both hands, thereby facilitating the opening and closing of the chuck.

The above-mentioned means made it easier to grip the gripping piece, but based on the idea of the plan, when gripping each of the gripping pieces with both fingertips and opening the bag mouth to open and close the chuck, Since a force is required, the reaction force of the opening / closing force is transmitted to the bag body at the moment when the chuck is opened, and the bag body shakes. Therefore, the content may be scattered from the bag mouth by the reaction shake.

Therefore, there is also a method of opening the chuck by pinching the chucked portion with one finger of the one hand and shifting the fingertip in the lateral direction in order to prevent recoil shake due to the opening and closing of the chuck. However, in the above-mentioned opening knob with a bead, it is only prevented that the film surfaces of the facing portions where the bead is in contact are in close contact with each other, and the films in the peripheral portions above and below the chuck are in close contact with each other. Since it is in such a state, even if the chuck portion is picked up with a fingertip and the chuck is laterally slid as described above, there is a drawback in that the chuck cannot be opened / detached because the sliding of the chuck is not smooth due to the contact resistance.

In addition, there is provided a bag body provided with a large number of protrusions on the inner surface of the opening grip portion on the chuck so that a fingertip grasped does not slip. However, also in the case of this bag body, as in the case of the conventional bag body with a bead, the fingertips are prevented when the grip pieces are prevented from adhering to each other and the grip pieces are grasped with the thumb and the other fingers and the bag mouth is opened and pulled. The purpose is to prevent slipping.

Therefore, also in the case of this bag, when the zipper is opened by opening and pulling the bag mouth, there is a problem that the contents come out of the bag mouth due to reaction shake due to opening and closing.

In other words, the chuck biting is performed with the groove of the female claw and the arrow-shaped male claw fitted together, and there is sufficient fitting force to hold the contents, so from the direction of opening the bag mouth to the left and right. There is an occlusal force that does not easily open for pulling.

Therefore, as described above, a certain amount of force is required to open and close the chuck by expanding the bag mouth to the left and right, and on the other hand, a recoil shake occurs due to the opening and closing.

Further, as described above, a certain amount of force is required to open and close the chuck, and for that purpose, it is necessary to strongly grip the protruding strip of the knob piece. However, as a result, the fingertips may be hurt, so that the work efficiency is inevitably reduced in the case of the bag packing work for the articles, which requires the opening work of many occlusal chuck bag bodies.

The technical means for opening and closing the occlusal chuck in the conventional bag with a chuck as described above is intended to open and close the chuck by expanding and pulling the bag mouth, and the function of lateral sliding of the chuck is added. It has not been.

Therefore, when the consumer opens the chuck to take out the contents or when the contents are packed in the bag, the bag mouth must be widened and pulled, and the above-mentioned inconvenience occurs. .

As a supplementary explanation regarding the above, since individual bag bodies manufactured from the zipper film raw material are manufactured from the film raw material with the zipper closed, naturally the zipper of each individual bag material is also closed. It is what

<Means for Solving the Problem> The present invention is a bag body with a zipper having the following constitution means in order to solve the above-mentioned problems of the prior art.

That is, in a bag body provided with a synthetic resin male and female claw type chuck in the opening, a bag in the range of at least the edge of the opening from below the chuck position is a multi-layer film, and between the multi-layer films, Plural rows of thick ribs parallel to the chuck are placed close to each other, and the ribs are sandwiched by the multilayer film between the ribs. It is formed into a shape.

Further, in a bag body having a synthetic resin male and female jaw type chuck provided in the opening, a bag body in the range of the edge of the opening from below or above the chuck position is a multilayer film, and the bag above the chuck position is a multilayer film. A plurality of rows of thick ribs parallel to the chuck are arranged close to each other between the layer films, and the ribs are sandwiched by the multi-layer film between the ribs. The front and back surfaces of the film are corrugated.

Further, the rib strip may be formed of a harder material than the multilayer film.

<Operation> With the above structure, the plurality of ribs sandwiched between the multi-layer films prevent the bag opening from being deformed by its elasticity, and in turn, prevent the chuck from being deformed.

Also, due to the corrugated shape of the front and back surfaces of the bag film due to the sandwiching of the ribs, the film of the opening gripping piece part around the chuck is in contact with the uneven surface to prevent the adhesion of the part, and the unevenness on the surface side. The surface prevents the fingertips holding the knob pieces from slipping and facilitates opening and closing of the chuck.

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a bag made of a synthetic resin film, 2 is an opening portion thereof, and 3 is a male and female nail type chuck provided in the opening portion 2.

As shown in FIG. 2, the present invention uses at least the area 4a of the edge of the opening 2 (see FIG. 1) from below the chuck 3 as the multilayer film 1a, 1b in the body. A plurality of rows of thick rib strips 5 parallel to the chuck 3 are arranged between 1a and 1b, respectively, and the rib strips 5 are sandwiched by the multilayer films 1a and 1b between the rib strips 5. Rib strip 5
The ridge 6 having a wave shape is formed on the front and back surfaces of the bag film at the sandwiched portion. In addition, as shown in FIG. 3, the inner layer film 1b of the multilayer films 1a and 1b is extended over the entire range 4b (see FIG. 1) from the edge of the opening 2 of the bag 1 to the bottom, The entire bag body 1 may be formed of a plurality of films.

In addition, as another embodiment, as shown in FIG. 4, the range of the edge of the opening 2 is set as the outer and inner multilayer films 1a and 1b from below or above the position of the chuck 3, and The rib strips 5 may be sandwiched between the upper multilayer films 1a and 1b in parallel in a plurality of rows, and the bag film front and back surfaces of the sandwiched portions of the rib strips 5 may be formed with a corrugated ridge 6. .

In the above embodiment, the rib strips 5 are the multilayer films 1a, 1b.
Although a resin material of the same quality as the above may be used, a resin material that is harder than the resin material of the multilayer films 1a and 1b is suitable.

Further, the multilayer films 1a and 1b may be made transparent, and the rib strips 5 colored in arbitrary colors may be sandwiched.

Since the present invention has the structure as described above, the opening around the chuck 2 is prevented from wrinkling or deformation due to the elasticity of the plurality of ribs 5 sandwiched between the multilayer films 1a and 1b. Prevent deformation of 3. This prevents the chuck 3 from spontaneously opening and closing, and normally secures the occlusion of the male and female nails of the chuck 3.

Further, by sandwiching the rib strip 5, corrugated ridges 6 are formed on the front and back surfaces of the multilayer films 1a and 1b at the sandwiching portion of the rib strip 5 based on the thickness of the rib strip 5, and the ridge 6 is formed. 6, the inside of the knob piece of the opening 2 is in contact with the uneven surface so as to prevent the close contact. Further, when the gripping piece of the opening 2 is grasped by the fingertip and the chuck 3 is slid sideways to open and close the chuck 3, the protrusion 6 serves to prevent the fingertip from slipping. This improves the operability of opening the opening 2 of the bag body 1 and the openability of the chuck 3.

<Effects of the Invention> As described above, the ridges formed by ribs are formed on both sides of the multilayer film portion of the bag body with the chuck according to the present invention, so that the inner surfaces of the film are prevented from being closely attached to each other at the chuck upper and lower portions. Therefore, by grasping both base parts of the chuck with one fingertip and sliding the fingertips in the left and right lateral directions, the chuck part can be easily slid without receiving frictional resistance due to close contact, and a quiet chuck opening and closing without recoil can be performed. It can be performed.

Therefore, unlike the bag according to the prior art, the contents do not pop out from the bag mouth due to the reaction and swing when the chuck is opened and closed, and the consumer is not caused an unexpected loss.

In addition, as described above, since the raised portion by the ribs is also formed on the outer surface of the multilayer film, the sliding of the fingertip is prevented and the lateral sliding of the chuck can be facilitated.

Furthermore, since the rib strip of the present invention is not formed directly on the film surface, but is raised by the sandwiching rib, the film is extremely soft to the fingertip when picked. Therefore, even when the chuck is opened and closed before packing the articles into bags, efficient work can be performed without damaging the fingertip.

Further, when the rib strip of the present invention is molded from a resin harder than the multilayer film, the desired shape of the rib strip is clearly realized, so that the desired effect of the rib can be further enhanced.

In addition, when the multilayer film portion sandwiching the ribs in the bag body is set to reach the opening portion slightly below the position of the chuck, since the base of the chuck is the multilayer film and has a thick shape, There is an effect in the manufacturing process that the chuck can be stably formed, and the occurrence rate of wrinkles around the base of the chuck is reduced, and further, there is an advantage in terms of appearance as a product.

Also, by designing the rib strips sandwiched in the desired color, it is possible to obtain a design effect of a relief pattern.
