Description

[Detailed description of the invention] The present invention relates to a tamper-proof outer container for bottled cosmetics, etc., and more specifically, before a consumer etc. opens the product after purchasing the product, it is in an unopened state and the contents are in an unopened state. The present invention relates to an outer container that can ensure that objects are in unused condition.

Bottles, plastic containers, etc. (hereinafter referred to as bottles, etc.) that conventionally housed cosmetics, medicines, foods, etc.
Paper containers have generally been used as external containers for storing. However, paper containers are expensive to manufacture, so although they are suitable for packaging containers for high-end products, they are not suitable for packaging low-priced products. In addition, paper containers can be opened and closed easily and easily.
For example, it was possible to commit fraud by opening a box while it was on display, taking out a bottle, etc., deleting some of the contents, and then putting it back in its original state. In order to prevent such fraudulent acts, stickers are placed on the opening and closing parts, but not only are they not perfect for preventing fraud, but they also complicate the packaging process, increase costs, and complicate the opening operation. This results in various inconveniences.

In addition, for the above-mentioned products, manufacturers and sellers are required to notify consumers in advance that the product is unopened and unused, but conventional outer packaging does not It has been difficult to fully satisfy these demands.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to ensure that the contents remain unused until the consumer opens the package himself, and also to ensure that no utensils are removed when opening the package. To provide a tamper-proof outer container from which the contents can be taken out with a simple operation without needing to be removed.

In order to achieve the above object, in the tamper-proof outer container according to the present invention, the peripheral wall of the container main body, which is hollow and cylindrical and has at least one end open, is formed from a body and one or more release bands, and the body The part and the release band are formed simultaneously from different types of incompatible synthetic resins, and the release band extends in the axial direction from one end of the container body toward the other end and is separable from the body. A through hole is formed in the release band, a protrusion is formed in the lid body that can be closed at one end, and the protrusion is fitted into the through hole to close the lid body. The cover is attached to the container body, and when the release band is pulled and peeled off from the body, the lid comes off from the container body.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 in the figure indicates an outer container according to an embodiment of the present invention, and a bottle 2 filled with cosmetics or the like is housed inside the outer container 1. The outer container 1 includes a hollow cylindrical outer container 3 formed by extrusion from a soft synthetic resin and open at both ends, and a synthetic resin container 3 that is attached to each open end of the outer container to close it. It consists of a top cover 4 and a bottom cover 5. The peripheral wall of the container body 3 includes a body portion 3a and a pair of separation bands 3b extending over the entire axial length of the container body.
-3b, and these body parts and release bands are molded from different types of resins that are not compatible with each other,
Each release band 3b is integrally joined to the circumferential end of the body. Examples of combinations of resin materials forming the body portion 3a and the release zone 3b include polyethylene and ionomer, polyethylene and EVA,
Possible combinations include adhesive polyethylene and nylon, high-density polyethylene and low-density polyethylene, and these are formed simultaneously by extrusion molding.
The bonding surface between the body 3a and the release band 3b has a bonding strength that allows peeling as described later, and in order to prevent the bonding strength from becoming excessively low, the bonding surface is made in the thickness direction of the peripheral wall of the container body 3. It is preferable to increase the area by tilting it to the opposite direction.

A substantially inverted U-shaped slit 6 is bored in the upper part of the release band 3b, and a top cover 4 is attached to the upper end of the container body 3. A protrusion 8 is provided on the side wall of the upper cover 4, and when the upper cover 4 is attached, the protrusion 8 causes the upper part of the release zone 3b surrounded by the slit 6 to protrude outward more than the other parts. It fits into the widened slit part. The lower surface of the protrusion 8 is preferably formed into a tapered shape,
To facilitate insertion of an upper lid 4 into a container body 3. On the other hand, a through hole 7 having a width shorter than the width of the release band is bored in the lower part of the release band 3b, and a protrusion 9 formed on the side wall of the bottom cover 5 fits into this hole 7. ing. The bottle 2 is housed in the container body 3 through the opening at its upper end after the bottom cover 5 is fitted onto the container body 3, and then the top cover 4 is fitted thereon.

In the state shown in FIG. 2 of the outer container 1 configured as described above, the protrusion 8 of the top cover 4 is inserted into the expanded slit 6 of the release band 3b, and the protrusion 9 of the bottom cover 5 is inserted into the through hole. 7, these top and bottom lids are fixed to the container body 3 and form an outer container that is guaranteed to remain unused until opened by a consumer or the like. In order to unseal the outer container 1 from this state, the outwardly protruding portion of the release band 3b is pinched with fingers and pulled downward, and the release band is removed from the body 3a formed of a different type of resin. Peel it off. Then, as shown in Figure 4,
Since the projection 9 of the bottom cover 5 and the through hole 7 are disengaged,
By peeling off each release band, the bottom cover 5 can be removed and the bottle 2 can be taken out. Also, in this way, the release zone 3
After the outer container 1 is opened by peeling off the outer container 1, it cannot be reattached to the body 3a, so the fact that the outer container 1 has been opened becomes obvious, and there is no room for the above-mentioned fraudulent acts.

In the above embodiment, the peeling strips 3b are provided at two locations, but the number can be set arbitrarily, including the case where the stripping strips 3b are provided at one location. Further, the shape of the outer container 1 is not limited to a cylindrical shape, and various shapes are possible depending on the shape of the non-contained items.

Furthermore, in the above embodiment, the container body 3 with both ends open was formed by extrusion molding.
It is also possible to use other molding methods, such as injection molding or blow molding, to produce a container body that is closed at one end (the upper end in the illustrated embodiment).

As described above, in the outer container according to the present invention, the peripheral wall of the container main body, which is hollow and cylindrical and has at least one open end, is formed from a body and one or more release bands, and the body and the release band are They are formed simultaneously from different kinds of incompatible synthetic resins, and the release band extends in the axial direction from one end of the container body toward the other end, and is releasably joined and integrated with the body. A through hole is formed in the release band, a protrusion is formed on the lid which can be closed at one end, and the lid is attached to the container body by fitting the protrusion into the through hole; Since the lid comes off from the container body when the release strip is pulled and peeled from the body, this fact becomes obvious once the lid is opened, and this eliminates fraud, which has been a problem with conventional paper boxes. The act can be almost completely prevented. Further, the operation of opening the lid body can be done by simply pulling the release band, so no tools are required, which is convenient. Furthermore, manufacturing and assembly (packaging) can be done easily and costs can be reduced, and if the container body and peeling strip are made of transparent resin, the contents can be seen through during display.
It has various effects that conventional paper boxes do not have.

Further, the other end of the container body opposite to the one end is opened, and a substantially inverted U-shaped slit is formed near the other end of the release band, so that the other end of the container body is opened. A second lid that closes is provided, and a protrusion is provided on the second lid, and when the second lid is attached to the container body and the protrusion is located inside the release zone, When the protrusion pushes out the portion surrounded by the slit so that it is engaged with the slit, the end of the release band protrudes outward from the outer surface of the container body. The release band can be easily peeled off by picking this end with the fingertips, resulting in excellent usability.
