Description

A coupling makeup of a twofold container

The present invention relates to a cup that can be kept tight as well as thermal insulation by keeping various printed matters in the inner space secured by assembling the inner container made of stainless steel and the outer container made of plastic.

In order to embed the advertisement printed on the double cup in which a conventional inner space is formed, both the inner container 10 and the outer container 30 are molded in plastic so that the joints can be assembled by fusion by high frequency or the like. This ensures confidentiality even when the printed advertisement is embedded.

However, in this case, the processing by fusion is not economical due to the time and economic aspects did not get a great response to consumers.

Therefore, in recent years, it has been receiving a great response to consumers because of the low price by assembling by the engagement means, but the disadvantage of this is that when the cup is in contact with hot and cold water, the engagement part is opened by deformation due to shrinkage and expansion of the plastic. As a result, water is penetrated, which makes it difficult to preserve advertisements, and it is a disadvantage that insulation is not possible because it is made of only plastic.

Therefore, when the inner container 10 is made of stainless steel and the outer container 30 is assembled into plastic, the outer container formed of plastic is brought into close contact with the inner container, and then the pressed part is molded into plastic by pressing the inner container of the closely contacted part. It is produced by enclosing the outer container, but this is because the characteristics of the material properties of the stainless steel has not been practical because of the problem that the burst occurs.

The present invention is to solve the conventional problems as described above, the object of the present invention is to provide a double container that can be completely fixed while keeping the airtight container made of stainless steel and the outer container made of plastic. In order to achieve this, the present invention forms an annular protrusion on the neck portion of the inner container made of stainless steel so that the soft rubber packing can be tightly fixed, and then the outer container is engaged with the packing so that the airtightness is tightly coupled. It is characterized by one.

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

Double container according to the present invention is made of stainless steel as shown in Figures 1 to 4 and the upper end annular to protrude outward on the upper side of the inner container 10 having a U-shaped insert 11 The packing 20 having a width so as to be inserted into the insertion portion 11 of the inner container 10 and the inner container 10 in which the protrusions 12 are formed to be tightly fixed inside the annular protrusion 12 and the packing The outer edge of the lower edge is exposed to the locking projection 21 is formed to protrude, the outer projection 30 is formed with a key groove 31 is coupled to the locking projection (21).

At this time, the space portion 1 is formed between the container 10 and the outer container 30 so that various printed advertisements can be inserted to express various advertisements or designs.

At this time, when the press working to form the annular projection 12 so that the lid is coupled to the upper side of the portion where the annular projection 12 of the inner container 10 is to be formed 13 is formed will be.

In addition, when the packing 20 is inserted into the inserting portion 11 of the inner container 10, in order to facilitate insertion, the cutting portion 21 is formed at the distal end. The curved surface 24 is formed so that the space 23 is formed to have a pressure in order to compensate for the airtightness when the outer container 30 is coupled to the locking protrusion 21 of the packing 20. In order to form the concave portion 25 to the upper side of the locking projection 21 and to form the protruding frame 32 to engage the concave portion 25 in the outer container 30 is to maintain the airtight complement. .

In addition, in order to expose the contents of the advertisement, such as the advertisement sheet inserted into the inner space made by combining the contents and the outer container, it is preferable to use a material that can be viewed, and a separate handle for convenience of use. It can be formed.

Referring to the operation and effect of the present invention configured as described above, first, after forming the inner container 10 made of stainless steel according to the shape of the cup container, and processed the upper end portion to form a U-shaped insert 11 When the 20 is coupled to the inner container 10, the packing 20 may not be pulled out by the annular protrusion 12 protruding to the outside.

In addition, the packing 20 coupled to the inner container 10 is firmly engaged with the key groove 31 of the outer container 30 by the locking protrusion 21 formed at the lower end of the packing 20.

As described above, the present invention uses the packing of the stainless steel inner container and the plastic outer container to form a space part of a predetermined space and maintains airtightness so that it is firmly coupled so that there is no penetration of water, thereby keeping the contents stored between the inner container and the outer container. There is an advantage that can be stored longer.
