Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This device is a bag for waste, and its purpose is to make it easy to tie the mouth.

[0002]

[Prior art]

 Conventionally, various structures for closing the mouth of the synthetic resin bag have been proposed (for example, Japanese Utility Model Publication No. 4-32976). In many of the above-mentioned conventional inventions, an insertion hole such as a lace is provided in an annular shape along a joint portion of the bag, and the number of the lace is usually four.

[0003]

[Problem to be solved by the invention]

 The above-mentioned conventional device has a problem in that the structure is complicated, and the bag and the string are separate materials, so that the production line is complicated and the production price is soared.

[0004] In addition, there is also a problem that waste materials increase due to complete tightening cords and the like.

[0005]

[Means for Solving the Problems]

 However, the present invention has solved the above-mentioned conventional problems by reducing the number of tightening cords or the like.

That is, in the present invention, a sealing member is inserted into an annular gap provided along the mouth of a bag made of a synthetic resin film, and a part of the sealing member is fixed (with the sealing member being attached). If it is formed in an annular shape, it is not necessary to fix it). A synthetic resin bag characterized in that a draw-out opening for a closing ridge is provided in the mouth, and the bag is formed along the mouth of the bag made of a synthetic resin film. A synthetic resin bag characterized in that a closing ridge is inserted into the annular gap provided and fixed at one end of the closing ridge, and the other end of the closing ridge is provided at the opening. is there.

[0007] Another invented synthetic resin bag is characterized in that a cutout of a fastening strip is provided along a mouth of a bag made of a synthetic resin film, and the cut is provided in an annular shape. One or both of the short sides of the strip have no cuts, and the cuts are provided at the folded portions along the bag mouth.

[0008] Yet another invention is characterized in that one end of a zipper is fixed along the mouth of a bag made of a synthetic resin film, and an adhesive is layered on the other end of the zipper. And synthetic resin bags. In the above, there is an advantage that a hole cannot be formed in the bag if the folded portion of the bag mouth is used for cutting out the fastening.

However, in the case of a bag for storing relatively light objects (for example, burnable garbage), even if there is a hole in the mouth of the bag, since this portion is a lip, the edge of the hole is torn during handling. There is no such thing.

In the above, when the adhesive is room temperature adhesive, it is necessary to cover the adhesive with a separator. Instead of the adhesive, it is also possible to devise a method in which the tip is folded back, tied up and not easily come off. Also, it can be hooked when tied with a cut.

[0011]

[Embodiment of the invention]

 This invention is based on the idea of inserting a zipper into an annular gap provided along the mouth of a bag made of synthetic resin film, fixing a part of this tie, and pulling out the center part to the outside to bind the mouth. The present invention relates to a synthetic resin bag which can be used for a plastic bag.

[0012] Still another invention is to achieve the object with a minimum amount of material, for example, by cutting out or adhering a squeezing strip from a bag mouth, and taking synthetic resin into consideration in easiness of production. It is a bag.

[0013]

Embodiment 1 An embodiment of the present invention will be described with reference to FIG. The edge of the bag 1 made of a synthetic resin film is bent outward, and the lip 2 is inserted into an annular gap 3 formed by welding the lower edge 1a thereof. The outlets 3a, 3a of the zipper 2 are provided, and the zipper 2 is diametrically perpendicular to the outlets 3a, 3a. Part 2), the synthetic resin bag 4 of the present invention was obtained.

In the drawings, reference numerals 5 and 5 denote welded portions of the fastening strip 2. If one portion of the fastening strip 2 is a welded portion 5a and a drawer port 3b is provided on the opposite side of the welded portion 5a, the synthetic resin bag 4a of the present invention is completed (FIG. 1- (c)).

In order to tie the mouth using the synthetic resin bag 4 of the above embodiment, first, the zipper 2 is pulled out from the outlets 3a, 3a as shown by arrow 6, and Can be bound in the usual way using.

[0016]

Embodiment 2 Another embodiment of the present invention will be described with reference to FIG. The opening edge of the bag 1 made of a synthetic resin film is bent outward, and an annular gap 3 formed by welding the lower edge 1a of the bag 1 is provided with an opening 7 having an appropriate length (length to be able to bind the opening). In this case, one end of the zipper 7 is welded to the mouth of the bag 1, and the other end 7 a of the zipper 7 faces the outlet 8 provided in the annular gap 3. A synthetic resin bag 10 was obtained.

In order to bind the mouth portion of the bag body 1 with the synthetic resin bag 10, as shown in FIG. Bind in the usual manner using. The length of the fastening strip 7 in the above is appropriate, and the requirement is that the mouth of the bag 1 can be securely bound.

[0018]

Third Embodiment Another embodiment of the present invention will be described with reference to FIG. The edge of the bag 1 made of a synthetic resin film is bent outward, the lower edge 1a is welded, and cuts 12, 12 are provided in the bent portion 11 at predetermined intervals parallel to the edge. The fastening strip 13 was pulled out to obtain the synthetic resin bag 15 of the present invention.

In this case, the closing ridges 13 are provided symmetrically in diameter (front and rear) (FIG. 3A), but may be provided only on the front. In addition, the lip 13 can be provided relatively long (turning from the front surface to the rear surface).

In order to tie the mouth of the synthetic resin bag 15 of the above embodiment, as shown by an arrow 14 in FIG. 3B, the zipper 13 is pulled out and tied in a usual manner. In the above description, the lip 13 can be provided by cutting out a folded portion and a part of the bag body (FIG. 3E).

[0021]

Embodiment 4 Another embodiment of the present invention will be described with reference to FIG. Cuts 16 and 16 are provided in the rim of the bag 1 made of a synthetic resin film in parallel with the rim so that the ridge 17 can be cut out. For example, the front ends of the cuts 16 and 16 are cut inward respectively. 16a was provided to facilitate the cutting (FIG. 4- (b)), or the whole was cut (FIG. 4- (c)), to obtain the synthetic resin bag 18 of the present invention.

The lip 17 is provided on both the front and rear surfaces of the bag 1 (FIG. 4A), or is provided only on the front surface (FIG. 4-B).

In order to bind the mouth using the ridge 17 of the synthetic resin bag 18 of this embodiment, the ridge 17 is first cut off as shown in FIG. Bind. In the above, since the mouth portion of the synthetic resin bag 18 is weakened by cutting out the lip 17, the portion around the cut-out portion 19 of the cut-out hole that has been cut out is tied around the dashed line illustration (FIG. 4A). Is preferred.

[0024]

Fifth Embodiment Another embodiment of the present invention will be described with reference to FIGS. This is a synthetic resin bag 21 in which the central portion 20a of the lip 20 is welded to the upper outer wall of the bag 1 made of a synthetic resin film (FIG. 5). Further, one end 22a of the zipper 22 is welded to the upper outer wall of the bag 1, an adhesive 23 is layered on the other end, and a separator 24 is applied to the other end, and a synthetic resin bag 25 is attached. Was obtained (FIG. 6A).

In the above, it is also possible to use the adhesive simply as a sealing strip without layering the adhesive. In the case of the synthetic resin bag 21, it is tied in a usual manner, and in the case of the synthetic resin bag 25, the sealing strip 22 is wound, and then the separator 24 is peeled off and adhered.

[0026]

[Effect of the invention]

 According to this invention, there is an effect that a synthetic resin bag can be provided at a price substantially equal to that in a case where the production is simple and easy, and a lip is attached, and the lip is not provided.
