Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container whose outer peripheral surface is covered with a cylindrical cover film.
[0002]
[Prior art]
Some containers have a cover body detachably screwed onto a container body. In this type of container, a cylindrical cover film on which a product name or the like is printed may be placed on the outer peripheral surface of the container body.
[0003]
[Problems to be solved by the invention]
However, the conventional container has a problem that the cover film may be inadvertently detached from the container body because the container body is simply covered with the cylindrical cover film.
[0004]
In addition, since the cover film is covered only on the container body, there is a possibility that the lid can be opened without permission at the time of display or the like.
The present invention has been made in view of the problems of the prior art as described above, and provides a container with a cover film that is capable of instantaneously determining whether the lid has been opened or not opened by restricting the lid from being opened without permission. The purpose is to do.
[0005]
[Means for Solving the Problems]
The present invention employs the following means in order to solve the above problems.
That is, the present invention includes a container main body, a lid that is detachably screwed onto the upper portion of the container main body, an annular fracture portion is provided above the lower edge by a predetermined dimension, and a lower portion than the fracture portion of the lid body. And a cylindrical cover film that covers the container body and is adhesively fixed to the entire outer peripheral surface of the container and printed with a product name, component display, and the like. .
[0006]
For example, the break portion may be formed like a break line by continuously providing elongated linear slits at predetermined intervals. However, the form of the breakage part is not limited to this, and in short, any form is acceptable as long as the breakage part can be broken by relatively twisting the upper part and the lower part of the lid. It doesn't matter.
[0007]
<Raw material of the present invention>
A resin film is used as the cover film. Specific examples include Poroso (trade name) manufactured by Toho Plastic Industry Co., Ltd., but are not limited thereto.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings of FIGS.
[0009]
[First Embodiment]
FIG. 1 is a cross-sectional view of an essential part of a cover film-equipped container (hereinafter referred to as a container) 1 according to the first embodiment of the present invention, and FIG. 2 is a perspective view of the container.
[0010]
The container 1 includes a cylindrical container body 10, a lid 20 that is detachably attached to the upper end of the container body 10, and a cover film 30 that covers the outer peripheral surface of the container body 10 and the lid 20.
[0011]
The container body 10 includes a mouth tube portion 12 on the upper portion of the body portion 11, and a male screw 13 is formed on the outer peripheral surface of the mouth tube portion 12.
The lid body 20 has a cylindrical shape, and an annular fracture portion 22 is formed at a position located a predetermined dimension above the lower edge. The fractured portion 22 is formed like a fractured line by continuously providing elongated slit holes at predetermined intervals, and the upper part 23 and the lower part 24 of the lid 20 are twisted in the opposite direction with the fractured part 22 as a boundary. Sometimes it can be broken. An internal thread 21 is formed on the inner peripheral surface of the upper portion 23 and can be screwed into the external thread 13 of the container body 10.
[0012]
The cover film 30 is made of resin and has a cylindrical shape, and is formed in a size that covers the entire area of the lower portion 24 of the lid 20 and the outer peripheral surfaces of the container body 10. As shown in FIG. 3, the cover film 30 before being attached to the container main body 10 and the lid body 20 is in the form of a single rectangular sheet, and an adhesive is attached to the entire inner surface thereof. While being wound around both outer peripheral surfaces of the lower part 24 and the container main body 10, they are adhered and fixed to the entire outer peripheral surface.
[0013]
In the container 1 configured in this way, the lower part 24 of the lid 20 and the container body 10 are integrally connected by the cover film 30, so that the fracture portion 22 of the lid 20 is broken, or The cover 20 cannot be removed from the container body 10 unless the cover film 30 is peeled off so that the container body 10 and the cover 20 can be rotated relative to each other. Therefore, when the cover film 30 is not peeled off and the broken portion 22 is not broken, it can be determined that the container 1 is unopened.
[0014]
This container 1 is used with the lid 20 openable as follows. That is, the lower part 24 of the lid 20 is held from above the cover film 30 with one hand, and the upper part 23 of the lid 20 is held with the other hand and twisted. Then, the fracture | rupture part 22 of the lid body 20 will fracture | rupture, the upper part 23 of the lid body 20 will be rotatable with respect to the container main body 10, and the lid body 20 can be removed now. The lower part 24 of the lid 20 remains bonded to the cover film 30 and is held in a state of being connected to the container body 10 via the cover film 30.
[0015]
Thus, when the fracture | rupture part 22 of the cover body 20 is fractured | ruptured, it can be judged that this container 1 has been opened.
Further, since the cover film 30 is bonded and fixed to the lower portion 24 of the lid 20 and the entire outer peripheral surface of the container body 10, the cover film 30 will not accidentally fall off the container body 10 and the lid body 20.
[0016]
Furthermore, if a brand name, a component display, etc. are printed on the cover film 30, the function as a label and the function as a packaging can be combined with one cover film, and manufacturing cost can be reduced.
[0017]
[Second Embodiment]
FIG. 5 is a sectional view of an essential part of a cover film-equipped container (hereinafter referred to as container) 1 according to the second embodiment of the present invention. The point in which the container in 2nd Embodiment differs from the thing of 1st Embodiment exists in the shape of the cover body 20. FIG.
[0018]
That is, the lid body 20 of the container 1 in the second embodiment has an upper portion formed in the small diameter cylindrical portion 25 and a lower portion formed in the large diameter cylindrical portion 26 having substantially the same outer diameter as the body portion 11 of the container main body 10. ing. A fracture portion 27 is formed at a step portion connecting the small diameter cylindrical portion 25 and the large diameter cylindrical portion 26.
[0019]
The breaking portion 27 is configured, for example, by arranging rectangular small holes continuously in a ring shape at predetermined intervals and forming a bridging portion that can break the small holes. The broken portion 27 can be broken when the small diameter cylindrical portion 25 and the large diameter cylindrical portion 26 are twisted in opposite directions.
[0020]
And the cover film 30 is adhere | attached on the whole outer peripheral surface of the trunk | drum 11 of the container main body 10, and the large diameter cylinder part 26 of the cover body 20. FIG.
Since other configurations are the same as those of the container of the first embodiment, the same reference numerals are given to the same mode portions in the drawing, and the description thereof is omitted.
[0021]
Also in the container 1 according to the second embodiment, the cover film 30 is not inadvertently dropped from the container body 10 and the lid body 20, and the container 1 is opened depending on whether or not the broken portion 27 is broken. Whether it is finished or not opened.
[0022]
Moreover, if a brand name, a component display, etc. are printed on the cover film 30, the function as a label and the function as a package can be combined with one cover film.
[0023]
【The invention's effect】
As described above, according to the present invention, since the cover film is bonded and fixed to the outer surfaces of the container body and the lid, the cover film is not inadvertently detached from the container body and the lid.
[0024]
Moreover, since the container main body and the lid are integrated by the cover film, the lid cannot be removed from the container main body unless the broken portion of the lid is broken. Therefore, the broken portion of the lid is broken. Whether the cover film-equipped container has been opened or not can be easily determined depending on whether or not it is open.
[0025]
Moreover, since the cover film combines the function as a label and the function as a package, the manufacturing cost can be reduced.
