Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a film packaging aid that facilitates the work of covering the outside of a container with a packaging film.

[Conventional technology]

2. Description of the Related Art Conventionally, there is a container for food or the like, which is covered with a packaging film having a heat-shrinkable property on its outer periphery and then heat-shrinked to be tightly adhered to the container. Conventionally, the work of covering the outer periphery of such a container with a packaging film is
It was done as shown in the figure. This work can be performed by inserting the container into the packaging film or by covering the packaging film from the outside of the container, but in both cases, the relative movement of the container and the packaging film is the same. .

The packaging film 11 is a cylinder formed of heat-shrinkable vinyl chloride or the like, and at least one end is opened to form an open end 11a, while the container 12 is a container body 1
It is a cylinder consisting of 3 and a lid 14 that covers the opening at the top. Then, the outer periphery of the container 12 was covered with the packaging film by inserting the container 12 held in the other hand from the bottom into the opening of the packaging film 11 held in one hand.

[Problems to be solved by the device]

However, since such a packaging film 11 is thin and flexible, the opening end 11a thereof is easily distorted. Therefore, conventionally, when the edge portion 14a of the lid 14 is projected outward like the container 12 of the same figure, the edge portion 14a and the opening end portion 11a of the packaging film 11 are part A of the figure. However, the container 12 cannot be put in the packaging film 11 any more, and the outside of the container 12 cannot be easily covered with the packaging film 11. In the case of mass production, there is a problem that production efficiency cannot be improved because it takes time and labor at this work stage.

Therefore, the present invention has been made in consideration of such a point, and an object of the present invention is to eliminate the interference between the opening end portion of the packaging film and the protruding portion on the side surface of the container and cover the outside of the container with the packaging film. It is to provide a film packaging aid that facilitates the work.

[Means for Solving the Problems]

This invention comprises a recess for inserting the container from either the upper or lower direction thereof and a positioning mechanism for arranging the container at the center of the recess, and the inner side surface of the recess has the packaging at the opening of the recess. Form an inclined surface having a diameter sufficiently larger than the opening end of the film, and having the same or slightly larger diameter at the bottom as the opening end of the packaging film, and gradually decreasing in diameter toward the bottom. A film packaging aid is configured to solve the above problems.

[Action]

The container is inserted into the recess of the film wrapping aid from either the top or the bottom of the container, and the container is placed in the center by the positioning mechanism. Then, the opening end of the packaging film is inserted into the opening of the recess while the packaging film is covered from the outside of the container. The operations of the container, the film packaging auxiliary tool, and the packaging film are relative, and it is substantially the same whether the packaging film is covered with the container or the container is inserted into the packaging film.

As the opening end advances toward the bottom of the recess, the inclined surface formed on the inner surface of the recess guides the opening end,
The distortion of the opening end is gradually corrected, and when reaching the end position of the inclined surface, the opening end has a predetermined shape along the inner surface of the recess.

Therefore, at the position of the protruding portion on the peripheral side surface of the container, the opening end of the packaging film advances along the inner side surface of the recess and passes between the inner side surface and the protruding portion, so that they do not interfere with each other.

〔Example〕

The structure of the embodiment of the present invention will be described with reference to FIG. The figure is a side cross-sectional view of the film packaging aid with the container and the packaging film inserted.

The container 12 is composed of a peripheral wall whose upper end opening is tapered with a large diameter, a container main body 13 having a bottom integrated with the peripheral wall, and a lid 14 fitted at the peripheral edge to the upper end opening of the container main body 13. lid
14 is attached so as to cover the mouth edge of the opening edge of the container body 13 from the outside, and the edge portion 14a of the lid 14 becomes a flange-shaped protruding portion on the circumferential side surface of the container 12 while fitting to the container body 13. The inner side of the mating portion has a concave shape and forms a recessed portion 14b. The packaging film 11 that covers the outside of the container 12 is a cylinder that is formed of a material having heat shrinkability as described above, for example, vinyl chloride, and has a taper from one end to the other end, and has a large-diameter end portion opened. To form the open end 11a,
The small-diameter end extends like an inward flange to form an annular bottom 11b. Then, the container 12, the packaging film 11
Both of them are turned upside down, and the downwardly directed upper portions thereof are inserted into the recesses 2 of the film packaging aid 1.

The film packaging aid 1 is a thick disk made of synthetic resin or the like, and has a flat circular recess 2 opened at the center of the upper surface. The bottom 2b of this recess 2 has a table 3 at the center.
This pedestal 3 has a shape that engages with the recess 14b on the upper surface of the lid 14 of the container 12 described above, and when the container 12 is inserted into this recess 2, it is fixed in the center of the recess 2. It becomes a positioning mechanism. Further, an inclined surface 4a is formed on the inner side surface 4 of the recess 2 so that the diameter gradually decreases as it goes downward. The inclined surface 4a starts from the opening 2a of the recess 2 having a diameter sufficiently larger than the opening end 11a of the packaging film 11,
The opening end 1 of the packaging film 11 at the height of the edge 14a of 14
It continues up to the inclined end 2c where the diameter is slightly larger than 1a. The inner side surface 4 below the inclined end 2c becomes a vertical surface 4b and continues to the bottom 2b.

As shown in FIG. 2, the concave portion 2 has an inclined end 2c at the edge.
It is formed at a position higher than 14a, and the inner side surface 4 has an edge 14a of the lid 14.

As shown in, the opening end 11a of the packaging film 11 is inserted into the opening 2a of the recess 2 and the packaging film 11 is gradually lowered downward.

The opening end 11a of the packaging film 11 is distorted as shown in FIG. 7B under the influence of the force of the hand gripping it, but the part distorted and protruding to the outside gradually becomes smaller in diameter. Abutting the surrounding inclined surface 4a and pressing force P toward the center of the recess 2
Receive. Then, as shown in FIG. 4 (a), by further lowering the packaging film 11, the pressing force P continues to be applied to the outwardly protruding portion as shown in FIG. 4 (b), and the shape is gradually changed. It will be corrected. Finally,
As shown in FIG. 5 (a), when the opening end 11a is lowered to the inclined end 2c of the inclined surface 4a, the opening end 11a is released as shown in FIG. 5 (b).
The distortion of “a” almost disappears and becomes a circle along the inner surface 4. Therefore, as shown in FIG.
They pass through the outside of the edge 14a, and do not interfere with each other.

Further, in the film packaging auxiliary tool 1 of the present embodiment, the opening end 11a of the packaging film 11 descends along the vertical surface 4b even after passing the inclined surface 4a, and the opening end 11a reaches a position lower than the lid 14. Since it can proceed, the container 12 can be inserted inside the packaging film 11 with a sufficient depth.

The film packaging aid of the present invention may be one in which the container 12 is inserted from above the packaging film 11 as shown in FIG. The film wrapping assisting tool 7 opens the recess 2 downward, and the bottom 2b of the recessing section 2 has a hole 15 penetrating the bottom of the film wrapping assisting tool 7. Then, air is evacuated from the hole 15 by a suction device (not shown), and the container 12 is sucked to move the container 12 together with the auxiliary tool 7 and insert the packaging film 11 from above.

By using this film packaging aid 7, it is not necessary to move the packaging film 11 having low rigidity and being easily crushed by hand or machine, and it can be made more suitable especially when mechanizing this work.

Further, the film packaging auxiliary tool is not limited to the one that is molded and processed by the synthetic resin or the like like the above auxiliary tools 1 and 7, and
It may be formed by pressing a metal plate or the like like the auxiliary tool 8 shown in the figure. With such a structure, it is possible to provide an auxiliary tool with higher productivity.

Further, the film packaging aid is not limited to the one in which the plane of the concave portion 2 is a perfect circle as in the above-mentioned embodiment, and a plane shape of the container and a shape suitable for the opening end of the packaging film can be selected. Therefore, as shown in FIG. 8 (a), the plane of the recess 2 may be formed in an elliptical shape, or as shown in FIG. 8 (b), may be formed in a quadrangle.

In addition, in the above example, the container in which the edge portion of the lid on the upper portion of the container serves as the protruding portion on the peripheral side surface of the container has been described. However, like the container 16 in FIG.
The auxiliary tool of the present invention is also effective for a container having a formed therein. Further, as in the container 18 shown in FIG. 1B, there is a protruding portion such as a handle 19a in the middle of the container body 19. It is also effective for various containers.
