Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement in the upper and lower opening ends of a synthetic fiber net bag having a net-like structure as a whole, such as an apple bag.

[Conventional technology]

Conventionally, as is well known, this type of synthetic fiber mesh bag is provided by the manufacturer with the upper open end sealed with a sealing metal fitting or closed with a sewing machine, and the user, such as a supermarket, stores the contents in the bag. It was common practice to heat-seal or sew an indicator label, such as the manufacturer's information, to the lower opening end after inserting the product.

[Problem that the invention attempts to solve]

However, sewing the display label on the user's side at supermarkets and the like is extremely troublesome. Therefore, as a means to solve this troublesome point, a means can be adopted in which the manufacturer attaches a display label to the upper opening in place of the conventional seal, and the user seals the lower opening. Therefore, in supermarkets and the like, all that is required is to pack the contents and seal the container, which speeds up and simplifies the operation, making it extremely convenient.

However, on the other hand, when sealing the lower open end, the bag itself is a so-called net structure, so it may not have a certain shape and is easily rolled up.
It is difficult to attach to a sealing machine because it is difficult to work with, and it slips easily, and it also has the disadvantage that it is easy to come off once attached.

Therefore, the purpose of this invention was to solve all of the above problems, and to make the work faster and easier, to prevent the lower opening edge from curling up as much as possible, and to improve the sealing machine. To provide a mesh bag made of synthetic fibers that can be easily attached to a bag and is difficult to come off once attached.

[Means for solving problems]

In order to solve the above problem, in a synthetic fiber mesh bag that has a net-like structure as a whole, a display label such as the manufacturer's indication is heat-sealed or sewn to the upper opening end of the synthetic resin mesh bag. A rigid part was formed by welding a plurality of filamentous molten synthetic resins having grooves at regular intervals in the width direction.

[Effect]

Therefore, it is not necessary to attach display labels or the like in supermarkets, etc., and it is sufficient to simply put the contents in the bag and seal or sew it with a sewing machine, making the work easier and faster. Furthermore, since the rigid part to which the molten synthetic resin is welded is formed on the lower opening end surface, the lower opening end surface exhibits shape retention and is prevented from curling up due to the reinforcing effect of the solidified molten synthetic resin. In addition, especially in this invention, the molten synthetic resin is not planar but filamentous,
In addition, since multiple pieces extend in the width direction, and grooves are formed at regular intervals by notches, scratches, etc., not only is appropriate rigidity given to the open end, but it can also be folded into pieces at the position of the grooves. Even though it is rigid, it is extremely easy to fold and can be easily attached to a sealing machine. Moreover, since a plurality of filamentous molten synthetic resins are welded together, the opening end surface becomes uneven and has an anti-slip effect, so once it is attached to the sealing machine, it is difficult to remove. Therefore, the mesh bag of this invention has the advantage of being extremely easy to seal.

〔Example〕

The drawing is a schematic perspective view showing an embodiment of the mesh bag according to the invention, in which 1 is a display label such as a manufacturer's label sewn to the upper opening end of the synthetic fiber mesh bag, and 2 is a plurality of display labels on the lower opening end surface. This is a thread-like molten synthetic resin welded in the width direction, and constitutes a rigid part 3 by tightening or machine sewing the sealing fitting. Particularly in this embodiment, thread-like molten synthetic resin is continuously welded, and cutouts 4 as grooves are formed at regular intervals. This is to make it easier to fold at the position of the notch 4. Particularly when setting it in a sealing machine, it can be folded into an organ shape or a bellows shape, which has the advantage of being easy to attach to the sealing machine. It should be noted that the groove portion may not be the notch 4, but may simply be a scratch, and the molten synthetic resin may be welded in a so-called discontinuous manner without hanging the resin at the position corresponding to the notch 4.

Since this embodiment employs the above-described configuration, in a supermarket or the like, the contents can be poured into the bag through the lower opening end, which has an anti-rolling effect, and the bag can be attached to a sealing machine in a state where slipping is prevented.

By the way, although the notch 4 is specifically formed in this embodiment, the present invention is not limited to this. Even if it is not formed, the effect of preventing the lower opening end from curling up and slipping can be sufficiently achieved. Also, from that point of view, it is not necessary to use multiple pieces. However, if a configuration is adopted in which one filamentous resin is welded, for example, a set of two or more filaments is adopted, the molten resin wraps around the back surface during welding, and a special effect can be obtained in that reliable welding and fixation can be achieved.

[Effect of idea]

As described above, this invention adopts a configuration in which display labels are attached in advance to the edge of the upper opening, making it possible to simplify and speed up work at supermarkets, etc., as well as providing rigid parts on the edge of the lower opening, especially at regular intervals. Since we have formed a rigid part by welding multiple filamentous spacing synthetic resins with grooves in the width direction, we can not only reinforce the lower opening end face, but also make it easy to fold into a bellows shape despite being a rigid part. Because of this, it can be installed extremely easily on a sealing machine. Furthermore, it has an anti-slip effect and is difficult to remove once attached, making sealing work extremely easy. This also contributed to further improving workability.
