Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an assembly bag.

[Prior art and its problems]

Conventionally, when products or waste are placed in bags made of plastic film, etc.

The methods of closing include: ■ Squeezing and bundling the film at the top of the bag and tying this part, or * Bundling the film at the top of the bag and tying this part with a separate string or wire.
There is.

In the case of the above knotting method (■), it is necessary to leave a considerable portion of the upper part of the bag for knotting, and the amount that can be stored is small compared to the size of the bag body.

Furthermore, once tied together, it is difficult to untie them, making it troublesome to add or change stored items.

On the other hand, in the case of the method of tying with a string (■), although there is not much allowance for tying at the top of the bag, it is necessary to prepare a separate string or wire, and the work of tying the string is troublesome for one person. There are cases. Furthermore, if there are many items to be stored, the tied string may shift and come off the bag during transportation.

An object of the present invention is to provide a bag whose mouth can be reliably and tightly closed.

[Means to solve problems]

The assembly bag of the present invention has a part of the string for closing the bag body,
It is fixed to the upper outer peripheral surface of the bag.

[Effect]

Since the string for closing the bag is only partially fixed to the bag, it can be wrapped around the top of the bundled bag.

〔Example〕

In FIGS. 1 and 2, αα is an assembly bag according to an embodiment of the present invention. This assembled bag has the center of a separate string 03 attached to the upper outer peripheral surface of a bag body αD made of plastic film, paper, etc. using an adhesive tape piece α3. Therefore, after putting products etc. into the bag α0, the upper parts of the bags (11) and (7) are bundled together and the container α2 is wrapped around this part, thereby easily closing the bag a. That is, as shown in FIG.
Wrap the string α2 around the bundled part of the upper part once or twice, insert the remaining part between this wound part and the bag body αV, and pull it. The bag will not naturally unravel and can be reliably closed. Moreover, if the above procedure is reversed, the opening operation is easy, and even if it becomes necessary to add or change the stored items, it is easy to open and reclose the bag. However, the method of fastening the string α2 is not limited to the above procedure;
- The ends may be tied together.

In this embodiment, the string az is fixed at its center, but the fixed part is not particularly limited as long as the string @ is fixed to the bag body (Ill) with a part of it. For example, one end of the string It may be fixed to the bag body αD.Also, if the string O2 is arranged below the upper end αa of the bag body at a predetermined distance as in this embodiment, this bag portion can be bundled and the string a2 It can be wrapped around the bag and transported by grasping the bag film above the string QZ.In order to improve the airtightness of the bag, the bag film above the attachment point of string a2 is bundled and folded downward. The string α2 may be wound from above. However, the attachment point of the string α2 is not limited to this, and may be placed above or below the present embodiment.

Furthermore, there is no particular limitation on the length of the string (■). As shown in Figures 1 and 2, the length may be necessary and sufficient to wrap around the bundled bag αD, or as shown in Figure 3, the bag may be placed in a plastic container 09 or the like. The length may be such that when the bag is unfolded and the upper end α of the bag is folded back to the outside of the open end of the container α9, it can be tied and fixed from above. By fixing the bag αG to the container 051 or the like in this manner, it is possible to prevent the bag ttn from slipping down into the container αω due to the weight of products, waste, etc. when they are thrown into the bag.

This is particularly advantageous when working with people.

In the above embodiment, only one string @ is attached, but
The number of strings is not limited to this, and may be two or more. At that time, a plurality of them may be attached to the same location on the bag, or each may be attached to different locations. In the latter case, the string to be wrapped can be selected depending on the amount of stored items and the length of the folded portion.

Further, the string α2 may be formed of an elastic string. In that case, when closing the bag αD, simply wrap this elastic string around the top of the bundled bag and push the remaining part of the string between the wound part and the bag αD. The elasticity ensures that the string will stop and will not come undone. In addition, this elasticity causes the closing portion to be further tightened, making the bag more completely sealed. On the other hand, as described above, when fixing to the plastic container 09 or the like, if an elastic string shorter than the outer circumferential length of the container α9 is used, the elasticity improves the adhesion to the container a5.

Assembled bag (1 (I) shown in Figure 4 is characterized in that the string is formed into a loop shape.The loop-shaped string Q6+ can be wrapped around the upper part of the bundled bag body. Any length may be used, but especially when using a bag with the same length as the outer circumference of a plastic container Uω, the bag αυ is folded back to the open end of the container, and this ring is The bag body (111) can be prevented from slipping down simply by hooking the string αe.

In addition, when this loop-like string Oe has elasticity, the string α
If the length of e is made shorter than the outer circumference of the plastic container 09 etc., the bag αD can be securely and easily fixed to the plastic container etc. by the elasticity of the string.

The ease of closing the bag and the sealability of the closed bag are the same as in the embodiment using the elastic string described above.

In each of the above embodiments, the adhesive tape piece αJ was used to fix a part of the string (2) αe, but the fixing means is not limited to this, and adhesive may be applied, It may be heat welded.

Although not shown in the figure, if the bag is made into a double bag and the string is fixed only to the outer film, the inner film will be damaged by pulling the string strongly, even if the film at the fixed point is damaged. The contents will not come out because it is not exposed to water.

〔Effect of the invention〕

In the assembled bag according to the present invention, the bag can be easily closed by gathering the upper part of the bag body together, winding a string over the bundle, and securing the bag. Since a portion of the string is fixed to the bag body, the wrapped string will not shift and come off the bag body during transportation, and the closure will be reliable.
