The present invention relates to a vinyl container for packaging an object, and more particularly, to a method of manufacturing a vinyl container in a bundle by forming a plurality of vinyl containers of a predetermined standard and attaching a plurality of them, and storing and withdrawing the bundled vinyl container bundles. It relates to a vinyl container case that can be used.

In general, a vinyl container (envelope) is extruded from a synthetic resin material such as polyvinyl chloride, polyethylene, and molded into a cylindrical notification form, and after cutting it, one part is heat-sealed and manufactured to a certain standard.

Such vinyl containers are manufactured to contain liquid as well as solid items, and are widely used in the form of roll bags in food sales corners such as large discount stores and department stores. The rollback used by unwinding the vinyl container is wound in a film form by forming a cut-out part in a dotted line at a certain distance from the fusion part for sealing. This rollback takes up less occupied space when used and can be used to unwind it in a wound form so that it is easy to arrange and store, and the unit price is low and economical. However, since it is mounted without a case and is easily contaminated, there is a problem of cleanliness and phase, and one hand grabs and pulls the vinyl container that is cut by the other while holding the inner part of the vinyl container that is not cut. Because it must be cut off, it was not possible to use it with one hand.

In order to solve the above problems, the cutouts were folded in a continuous vinyl container formed at regular intervals, stored in a rectangular case, pulled out of the case by a predetermined length, and cut out from the cutout. When using a vinyl container case containing such a vinyl container, the problem of cleanliness and hygiene could be solved. However, after about half of the use of the vinyl container, the outlet of the case and the upper end of the vinyl container are far away, thus creating a lot of space. There was a problem that the top of the vinyl container, which should be slightly exposed to the outside of the vinyl container to be pulled out, fell into the inner space of the case and it was difficult to pull out the remaining vinyl container. When the upper part of the vinyl container, which should be partially out of the case, falls into the inside of the case, a finger must be inserted through the small case outlet to pull out the upper part of the plastic container from the inside of the case. There was a very uncomfortable disadvantage. In addition, when the plastic container is used halfway, the plastic container floats in the inner space of the case, so that the frictional force is low and the remaining weight of the plastic container is light. A flaw was found that could not be cut off but instead slipped out.

Accordingly, an object of the present invention is to provide a method for producing a bundle of vinyl containers to be stored in the case by producing a number of vinyl containers of a certain standard, and then laminated to a number of them to solve the above-mentioned drawbacks. .

Another object of the present invention is to provide a vinyl container case that can be used to take out the stack of laminated vinyl container attached.

And allowing the laminated vinyl container to be attached to the vinyl container located below.

According to one embodiment of the vinyl container case accommodated in a stack of laminated vinyl container according to the present invention for achieving the above another object, the upper or one side of the case is formed with a blowout port for taking out the vinyl containers stored therein In the case for storing the vinyl containers so that they can be taken out one by one, the vinyl containers are stacked so that their openings face in the same direction, and the vicinity of the openings are separated by the output when drawing out from the case. In a state in which it is attached and bonded by an adhesive having an adhesive force, it is folded in an S shape to be stored in an inner space of the case.

According to another embodiment of a vinyl container case accommodated in a stack of laminated vinyl container according to the present invention for achieving the above another object, an outlet for extracting the vinyl containers stored therein is formed on the top or one side of the case In the case for accommodating the plastic container one by one, the case is formed by a perforation line integrally with the bottom surface of the case is pushed inward along the perforation line formed on the bottom surface with a finger on the bottom surface of the case is cut off And a support for protruding into the inner space of the case and pushing up the vinyl containers in the case, wherein the vinyl containers are stacked such that their openings face in the same direction, and the vicinity of the openings is applied to the withdrawal output from the case. By adhesive having a degree of adhesion In the complex are combined state, characterized in that fold into S-shape to be received in the inner space of the case.

According to another embodiment of the vinyl container case accommodated in a stack of laminated vinyl container according to the present invention for achieving the above another object, an outlet for extracting the vinyl containers stored therein is on the top or one side of the case A case is formed, the case for storing the vinyl container to be drawn out one by one, comprising a support made of an inverted V-shaped plate member, which is seated on the bottom of the case to elastically support the vinyl container, the support is When the vinyl containers are mounted thereon, they are lowered while being unfolded, and as the amount of the vinyl containers seated on the support decreases according to the use of the vinyl containers, the vinyl containers are lifted up by elasticity, thereby raising the vinyl containers. The top surface is positioned close to the outlet of the case, and the vinyl containers have their openings. Are stacked so as to face in the same direction, and in the state where the vicinity of the openings are attached and bonded by an adhesive having an adhesive force such that the vicinity of the openings is separated by the output force when drawing out from the case, the inside of the case is folded in an S shape.

The present invention passes the adhesive coating machine 30 through the feed roller 22 from the feed roll 20 in a state in which the double-ply open vinyl container fabric 10 is rolled up and down. Then, in the adhesive coating machine 30, the adhesive 12 is applied to the vinyl container fabric 10 to be supplied at a predetermined interval. Specifically, the adhesive 12 is applied in a dot form to a predetermined area, preferably a small area, once for each vinyl container that is cut and cut in a later step. The application of the adhesive 12 in such a small area is to allow the vinyl containers to be attached to each other to fall off with a slight force, in addition to the adhesive 12 used here also at a constant force (external force) It is desirable to have a cohesive force, such as glue, that can easily come off. The adhesive 12 may be variously applied as long as the adhesive 12 may perform the desired function as described above. Further, the position where the adhesive 12 is applied is preferably near the top opening of the vinyl container 14. When the laminated vinyl container 14 is withdrawn from the case (not shown), if the adhesive 12 is applied near the container opening, the opening of the next vinyl container 14 comes out with a predetermined portion. This is because it is possible to reduce the effort to open the container opening.

The adhesive 12 applied to the vinyl container fabric 10 at an interval in the adhesive spreader 30 is transferred to a blower 32 and dried by hot air. Then, while passing through the fusion machine 40, the vinyl container fabric 10 is heat-sealed at regular intervals. That is, the heat-sealed portion 16 of a linear shape is formed on the vinyl container fabric 10 at a predetermined interval in a direction perpendicular to the supplied direction, so that the double-layered vinyl container fabric 10 is blocked at an internal space at regular intervals. do.

The vinyl container fabric 10 having the heat-sealed portions 16 formed thereon at regular intervals is cut in the vicinity of each of the heat-sealed portions 16 of the vinyl container fabric 10 by the cutter 50 to form a bag-shaped vinyl of a predetermined standard. The container 14 is manufactured. At this time, the front of the cutter 50, the withdrawal roller 24 is provided with the cutting blade 52 of the cutting machine 50 while feeding the vinyl container fabric 10 to be equally superimposed on the previously stacked and stacked vinyl containers (14) ) Cuts the vinyl container fabric 10 and at the same time the pressing member 54 is pressed against the adhesive 12 portion of the vinyl container so that the laminated vinyl container 14 is attached to the lower vinyl container. Therefore, the openings of the vinyl containers to be laminated are laminated to each other by the adhesive 12 applied near the openings while facing the same direction. In this way, the next vinyl container is cut and attached to the bundle of laminated vinyl containers 14 continuously. On the other hand, the moving roller 26 is disposed between the take-out roller 24 and the fusion machine 40 to adjust the distance between the heat-sealed portion 16 and the cutting line.

The bundle of laminated vinyl containers in this manner is folded in an S shape along its longitudinal direction, and finally made into a pre-capable state that can be stored in the case. Then, the case is accommodated in the case, the state accommodated in the case will be described later in detail in the description of the vinyl container storage case.

In the present invention, the support 80 for supporting the bundle of the vinyl container 14c may be configured as a separate member from the case 70c body, unlike the first to third embodiments described above. That is, as shown in Fig. 14, the support 80 is a form in which the plate having elasticity is bent in a substantially inverted V shape, and the material is preferably thick and elastic paper or plastic. In particular, the support 80 accommodates the inverted V-shaped plate member inside the case 70c, but the ends 80 of the support 80 in the original inverted V shape without the load of the support 80 is 82a, 82b ) Is preferably configured to be in close contact with the inner bottom edge of the case (70c). Then, the vinyl paper 14c is mounted on the support 80 to act as a load on the support 80 so that the support 80 is unfolded in a single shape as shown in FIG. 16, in which case the support 80 ) Both ends of the case 70c are slightly rolled up on the inner bottom edge of the case 70c to increase the restoring force restored to its original state when the load on the support 80 decreases. When the amount of the vinyl containers 14c seated on the support 80 is reduced by about half according to the use, the support 80 is restored to the inverted V shape by elasticity as shown in FIG. 17 and the vinyl container 14c. By raising the bundle so that the uppermost surface of the vinyl containers are in close contact with the inner upper surface of the case 70c, the space that is enlarged by using the vinyl container 14c is removed, so that the top of the vinyl container to be drawn out next is the case 70c. ) Can be eliminated by entering the interior space (78c). As a result, the vinyl container case 70c of the present invention has a height of the vinyl container bundle lowered by the user using the vinyl container 14c, and accordingly the elastic support 80 is adapted to meet the decreasing load of the vinyl container. The resilient restoration in the form of an inverted V shape is supported upwardly so that the vinyl container 14c is always positioned adjacent to the ejection portion 72c of the case 70c to facilitate withdrawal.

The embodiments disclosed herein are only presented by selecting the most preferred examples to help those skilled in the art from the various possible examples, the technical spirit of the present invention is not necessarily limited or limited only by this embodiment, the present invention Various changes and modifications are possible within the scope without departing from the spirit of the invention, as well as other equivalent embodiments.

As described above, the present invention is easy to take out the vinyl container in a single sheet by laminating a single sheet of vinyl container and adhesively attached so that a certain point can be easily separated and stored in the case as a bundle of vinyl containers to draw out one by one. There is this. Furthermore, the opening of the plastic bag with the perforated line is not smooth because the perforated line does not exist because it is not cut and separated from the perforated line of the continuously connected plastic bags as in the past, but completely manufactured in a single sheet and then attached to the laminate. It can eliminate the disadvantages. In particular, since the present invention does not require a perforated line, the present invention also has the effect of eliminating the difficult process of inserting the perforated line in a dotted line shape.
