Description

[Detailed description of the invention] "Industrial Application Field" This invention relates to a beautiful and convenient hollow-molded container made of synthetic resin for storing products such as refillable lipsticks.

``Prior art'' Conventionally, two parallel cut grooves were formed in a tube-shaped container made of synthetic resin, a release strip was formed between the grooves, and the cut groove was caused to break by pulling the release strip. There is one that is made to be opened after receiving it (Jikko 57-
Publication No. 14215).

In addition, a slit-like opening is provided in a packaging bag made of a synthetic resin film or sheet, the opening is covered with a tearable film or sheet, and the removal port is opened by tearing the adhesive piece. There is a method that does this (Japanese Utility Model Application Publication No. 130724/1983).

``Problem to be solved by the invention'' However, in the former case, there is a drawback that it is difficult to obtain cut grooves of appropriate depth; if it is shallow, it is difficult to break, and if it is deep, it may cause unexpected breakage. Another disadvantage is that the cut grooves spoil the aesthetic appearance.

Furthermore, in the latter case, after the slit-like opening is formed, the adhesive piece must be joined to the opening, which is time-consuming and disadvantageous in that the joining is unsightly.

The present invention aims to provide a container that is easy to manufacture, inexpensive, convenient, and beautiful without these drawbacks.

"Means for Solving the Problem" The present invention provides a container body 1 made of synthetic resin with an appropriate outer shape, and the container body 1 has an upper member 1a and a lower member 1b.
The container body 1 is formed from two upper and lower bodies, and is configured to be irremovably connected, and the container body 1 has one to several breaking bands 13..., 14... made of different materials integrally molded. It consists of intervention.

``Function'' The structure is as described above, and in use, after inserting the stored object, the upper member 1a and the lower member 1b may be irremovably connected. In order to do this, the container body 1 may be ruptured and opened at the boundary between the rupture bands 13 . . . , 14 . This boundary is the fracture zone 1
3..., 14... are made of different materials, and even though they are integrally molded, their bonding strength is relatively weak, making them easy to break.

``Example'' The illustrated one is a blow-molded container made of relatively soft synthetic resin that accommodates a refill lipstick cosmetic case 2, and is made up of two upper and lower parts: a long upper member 1a and a short lower member 1b. A container body 1 having a banana-shaped outer shape is formed.

Thus, the container body 1 has a concave groove 11 and a protrusion 12 at the end where the upper member 1a and the lower member 1b meet.
An engaging means 1c consisting of the following is provided to irremovably engage and connect.

In addition, the upper member 1a and the lower member 1b are integrally molded with several longitudinally thin fracture bands 13..., 14... made of different materials and communicated with each other. By blow-molding the resin for forming a break zone in a streaky manner into the resin for molding the container body supplied to the mold, the break zone is integrally inserted, and the upper member 1a and the lower part are broken at the boundary with the break zone. The member 1b can be broken and separated into several divided pieces 15..., 16..., and the material thereof is, for example, divided pieces 15...
..., 16... Therefore, the upper member 1a and the lower member 1b
If the main part of is polyethylene, the rupture zone 13...
..., 14... are polypropylene.

In the figure, 17, 17 are protrusions for receiving the cosmetic container 2. The protrusions are not necessarily required.

The above-mentioned upper member 1a and lower member 1b are blow-molded with a fracture band interposed therebetween, and as shown in FIG. The thin broken pieces 1d are broken off and separated.

Upper member 1a and lower member 1b formed in this way
The cosmetic container 2 containing refillable lipstick is housed therein, the concave groove 11 and the protrusion 12 are fitted together to engage and connect them, and an adhesive is injected into the engagement part, or
Alternatively, they are integrated by ultrasonic welding.

In addition, the contents are not limited to the above-mentioned cosmetic container 2.
Others are appropriate. Upper member 1a and lower member 1
It is convenient if both the cosmetic container 2 and b are made transparent so that the inside can be seen through, but this is not necessarily necessary in terms of appearance. In the above example, the appearance is a banana, but
Others are appropriate.

"Effects of the invention" According to the present invention, products such as refillable lipsticks can be stored and sold, and since the upper member 1a and the lower member 1b are connected, it is extremely easy to store the products, and, Can be sealed tightly.

Thus, the container body 1 has one to several fracture bands 13 made of different materials that are integrally formed and interposed.
..., 14..., the bonding force at the boundary with the breakage zone is moderate, making it easy to break when trying to open the package, and the package can be broken and opened like peeling a banana peel. Contents can be easily taken out, the required strength can be maintained and accidental breakage can be prevented, and moreover, almost uniform products can be easily and quickly manufactured by integral molding, and the yield is high. Can be provided at low cost.

Further, the container body 1 has a fracture band 13 made of a different material.
14... are integrated into one piece by integral molding, so the appearance can be made beautiful without any discomfort, and the shape can be made into bananas or other various shapes, making it interesting, and it is extremely useful in practical terms. be.
