Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package for storing a bag-like or sheet-like continuous plastic film used for garbage bags, packaging sheets, etc. It relates to something that can be taken out one leaf at a time in the form of a sheet.

Conventionally, various types of plastic bags such as polyethylene bags are placed in a storage container and the bags are removed from the storage container when necessary.

However, plastic bags have less frictional resistance on the surface than Teishu Paper, so the fold-in hop-up method used with Teishu Paper cannot be used.
The next bag after the bag that was taken out did not come out of the outlet, so it could not be put to practical use as it was. For this reason, continuous plastic bags with perforations are folded up, the folded bags are stored in a storage box, and when the bags are taken out, the perforations are hooked onto the corners of the storage box. There is one that has a structure in which each leaf is separated by using the same method (Japanese Utility Model Application Publication No. 54-52431). However, this structure has the drawback that the storage box must be held down when taking out the bag, and it is not as convenient as the hop-up removal method of a tissue paper paver. In addition, there is also a structure in which plastic bags are separated one by one and stacked on top of each other, parts of which are folded over each other in a flap shape to provide resistance in the removal direction, and then placed in a storage container. be.

However, this structure has the disadvantage that the bags cannot necessarily be taken out one by one, but several bags may be taken out at once, resulting in unnecessary bags being uneconomical. In order to solve these problems, the patent application
68412 (Japanese Unexamined Patent Publication No. 57-96948), the plastic film is folded so that the notches provided in the continuous plastic film exactly overlap, and an insertion member protruding into the storage container is inserted into the overlapped notches. The plastic film is stored in a storage container in the inserted state, and when the film is taken out, the first film of a predetermined length is pulled out by pulling the end of the film, and then cut off from the notch by the insertion member. , and when this film is cut off, the end of the next film, that is, the second film, is automatically pulled out to the outlet of the storage container by the action of the connecting part other than the cut, and the hops in the tissue paper are removed. A plastic film package has been proposed that has the simplicity of the up-take method and allows bag-like or sheet-like plastic films to be taken out one by one with certainty.

However, in such previously proposed plastic film packaging bodies, the insertion member that passes through the notch in the film is directly fixed to the storage container, making it difficult to manufacture the storage container and slowing down the plastic film storage process. It has the disadvantage that it is difficult to automate.

SUMMARY OF THE INVENTION An object of the present invention is to provide a plastic film package that improves the workability of film storage and allows the stored films to be reliably and easily taken out one by one.

The present invention facilitates the work of attaching the insertion member to the plate member by providing the insertion member that is inserted through the notch in the plastic film in a plate member formed of a separate member from the storage container. The present invention aims to automate the mounting of plastic film and the storage of plastic film into a storage container.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In FIGS. 1 and 2, a storage container 1 is formed of cardboard or the like in the shape of a hollow rectangular parallelepiped, and a double-sided oval outlet 2 is formed in the center of the upper surface of the storage container 1.

This outlet 2 is covered with a cover film 8 made of polyolefin, and a cut 9 is provided in the center of the cover film 8 along the longitudinal direction of the outlet 2. The inner side of the surface of the storage container 1 where the outlet 2 is provided is formed to be slightly smaller than the internal dimensions of the storage container 1.
A plate-like member 10 that can be easily taken in and out is arranged.

This plate-like member 10 is made of paper, plastic, etc., but the material is not particularly limited. Said plate member 1
A double-sided oval outlet 12 is formed in the center of the storage container 1, corresponding to the outlet 2 of the storage container 1.

In the longitudinal direction of this outlet 12, that is, on both sides in the left-right direction in FIG. 1, on the opposite side of the plate member 10 to the surface in contact with the inner surface of the storage container 1, that is, on the lower surface in the figure, insertion members 3 are provided facing downward. It is installed protrudingly. The insertion member 3 is made of a soft iron plate or the like that has a double insertion portion and can be split into two, and is configured in a T-shape in an initial state (not shown). Furthermore, the attachment of the insertion member 3 and the plate member 10 is as follows:
By gluing or by providing a bent tongue piece on the insertion member 3,
This is accomplished by making the tongue pass through the plate member 10 and projecting outward, and then bending and fixing the projecting portion. A folded plastic film 4 is inserted through the insertion member 3 provided on the plate member 10 and is locked therein. This plastic film 4 is
For example, as shown in FIG. 3, a long cylindrical film formed by an inflation method or the like is folded along the longitudinal direction to make it double, and the folded film 4 is folded in the middle in the longitudinal direction. Cuts 5 penetrating the double film 4 are provided at predetermined intervals at two locations in the width direction, and perforations 6 are formed over the entire length in the width direction including each cut 5. The film 4 is connected in the longitudinal direction at three points at the perforations 6, that is, at the center in the width direction and at both ends. In addition, a heat-sealed portion 7 is formed by welding on the same side in the longitudinal direction in the vicinity of each notch 5 and perforation 6, and this heat-sealed portion 7 extends parallel to the perforation 6 over the entire length of the film 4 in the width direction. It is provided in a direction perpendicular to the longitudinal direction. As shown in FIG. 2, such a film 4 is folded in half so that the notches 5 overlap each other in the center, and the film 4 of a predetermined length in this state is as shown in FIGS. As shown in FIG. 1 , when viewed from the side edges in the longitudinal direction, it is stored in the storage container 1 in a state of being bent into a substantially C-shape with an open bottom.

At this time, the two insertion members 3 are inserted into the overlapped cuts 5.
The insertion member 3 is inserted and passes through the entire film 4.
The ends of the film 4 are bent on both sides as shown in FIG. 2, and the film 4 is held therein. The film 4, which is thus locked onto the insertion member 3 of the plate-like member 10, is housed in the storage container 1 together with the plate-like member 10. In the manufacturing process of the plastic film package described above, first, the insertion member 3 is attached to the plate member 10 by the method described above, and after the cut 5 of the folded film 4 is inserted into the insertion member 3, the cut film 4 is locked. , these films 4 and plate-shaped members 10 are placed together in the storage container 1.
It is carried out by storing it inside.

．． In such a configuration, a predetermined length, that is,
To take out one bag of film 4, the leading end of the film 4, which is partially protruding from the take-out opening 2, is pulled out in advance.

At this time, when the folded film 4 stored in the storage container 1 is pulled out by one bag, as the film 4 is pulled out, the insertion member 3 is inserted into the notch 5. The end of the film 4, which is to become the second bag following the eye, gets entangled with the insertion member 3, and due to the resistance force, the middle part and both ends of the continuous cut 5 of the film 4, that is, the perforation. The part where 6 is formed will be torn. Also, when this bow is torn,
Since the film 4 is pulled out from the outlet 2 in the center of the storage container 1, when the film 4 is pulled out one leaf, the notch 5 in the film 4 has a certain width.
The insertion member 3 inserted through this notch 5 or the perforation 6
Since there is no resistance in the bowing direction until both ends connected at the perforation 6 are reached, a part of the center portion of the next film 4 connected at the perforation 6 comes out from the outlet 2. If you continue to pull out the film in this state, the next film 4 and perforation 6 will be removed.
Both end portions connected by are entangled so as to wrap around the insertion member 3. At this time, tension is applied to both ends, and the perforations 6 at both ends are cut first.After this, when the film 4 is further pulled, both ends of the next film 4 are pulled into the center by the resistance force entangled with the insertion member 3. Tension is applied and the central perforation 6 is cut. Therefore, a portion of the next film 4 is always exposed through the outlet 2. According to this embodiment as described above, the plastic film 4 can be reliably taken out one by one in a format similar to the hop-up method for tissue paper.

Moreover, since its structure is simple, it can be provided at low cost. Furthermore, in this embodiment, since the insertion member 3 for locking the film 4 is provided in the plate member 10 formed separately from the storage container 1, the installation work of the insertion member 3 is simplified, and the insertion member 3 The work of locking the film 4 to the storage container 1
Since it can be done outside the factory, it is easy to work and the manufacturing process can be easily automated. Furthermore, since the external dimension of the plate member 10 is formed to be slightly smaller than the internal dimension of the storage container 1, the plate member 10 is inserted into the storage container 1 with the plastic film 4 locked. In addition, since the workability is good and the dimensions do not differ greatly, the plate member 10 is moved after being installed in the storage container 1 and is connected to the outlet 2 of the storage container 1.
There is no fear that the outlet port 12 of the plate member 10 will be misaligned.

Furthermore, since the insertion member 3 is provided on the plate-like member 10, no force is directly applied to the storage container 1 when the film 4 is taken out, and therefore, the portion of the removal opening 2 of the storage container 1 is prevented from being damaged. This can be prevented, and the outlet 2 can be kept in its beautiful state at the beginning of use.

In carrying out the implementation, the plastic film 4 of the above embodiment may be a plastic film 14 with one longitudinal edge opened as shown in FIG. 5, or a single sheet of plastic film 14 as shown in FIG. A plastic film 24 made of a sheet may also be used.

Here, the plastic film 14 in FIG.
Each has two notches 15 at predetermined intervals in the longitudinal direction, and the positions including these notches 15 (where perforations 16 are provided,
Furthermore, bead seal portions 17 are provided on both sides of this perforation 16.Furthermore, the plastic film 24 shown in FIG. Perforation 26 at the position including
is provided. These finolems 14,2
4 can also be used to achieve exactly the same effect as described above. Further, the perforations 6, 16, and 26 do not necessarily need to be provided, or if they are provided, there is an advantage that the bow tearing becomes easier. Furthermore, the cuts 5, 15, 25 are not limited to two places, but may be in one place. Also, when there are two cuts 5, 15, 25, one is in the middle of the width direction of the film 4, 14, 24. If so, the other side may be partially cut off at the side edge of the film 4, 14, 24.
, 14, 24 in the width direction, and the insertion member 3 is inserted through both sides of the outlet, resistance can be provided when pulling the film 4, 14, 24 by the connecting portions on both sides. , and the next film 4, 14,
24 is reliably drawn out. Further, the bending of the plastic films 4, 14, 24 within the storage container 1 is not limited to the C-shape, but may be in other shapes. Further, the storing direction is not limited to the downward C-shape, but may be in an upward position with the open side facing the outlet 2, as shown in FIGS. 7 and 8. In this case, it is conceivable that the plate member 10 is disposed on the side of the opening 2 as shown in FIG. 7, or that the plate member 10 is disposed on the side of the insertion member 3 in the direction of the outlet 2 as shown in FIG. . When the side of the insertion member 3 is arranged in the direction of the opening 2 as shown in FIG. It only serves a function. Further, the insertion member 3 does not have to be split into two parts as in the above embodiment, and may be a simple rod-like, plate-like, string-like, or thread-like member. Any member that can be inserted into the notches 5, 15, and 25 may be used. At this time, the material of the insertion member 3 is not limited to the soft iron plate mentioned above.
Other metals, wood, paper, plastics, fibers, and other materials may also be used. In addition, when the insertion member 3 is composed of string or thread, the outer end of the insertion member 3 is fixed somewhere in the storage container 1, or the insertion members 3 on both sides are connected, so that the film can be It can provide enough rigidity to tear 4. In addition, the tip of the insertion member 3 does not necessarily need to be bent; for example, the length of the insertion member 3 should be approximately the inner dimension of the storage container 1, and the tip of the insertion member 3 should be bent.
1, the plastic films 4, 14, 24 can be held without bending. Further, the shape of the plate member 10 need not be a flat plate shape as in this embodiment, but may be a three-dimensional shape such as a semicircular, triangular, or trapezoidal side cross-sectional shape as shown in FIGS. 9 to 11.

In this case, even if the remaining amount of film 4 is low, the plate-like member 10 will not sink to the bottom of the storage container 1.
There is an advantage that the film 4 can be easily taken out. The shape of the outlet 12 provided in the center of the plate member 10 is not only a double-sided ellipse as in this embodiment, but also a circle, an ellipse, and a rectangle and a slit as shown in FIGS. 12 to 14. , slit bending, etc. can be considered.

Further, the shape of the outlet 2 of the storage container 1 is not limited to a double-sided ellipse, but may be a circle, an ellipse, a rectangle, a slit, a bent slit, or the like. Furthermore, in this embodiment, a cover film 8 made of polyolefin is provided at the outlet 2 of the storage container 1.
is mainly used to improve the appearance of the storage container 1 and to protect the stored plastic film 4 from dust, and may not be necessary from the functional point of view of taking out the films 4 one by one. .

The present invention provides a plastic film package having the above-described structure, so that plastic films of a predetermined length can be reliably taken out one by one, and the manufacturing process can be labor-saving. It has the effect of being able to.
