Description

  The present invention relates to a two-layer container, and more particularly, to a two-layer container that is thermally insulated and that can save materials and manufacturing costs during manufacturing.

  A two-layer container such as a pot or a pot having a two-layer structure currently on the market is made of stainless steel or glass.

  FIG. 1 shows the structure of a cup, which is an example of a conventional two-layer container. As shown in the drawing, the two-layer container A includes a gap space A3 between an inner wall surface A1 and an outer wall surface A2. The two-layer container A is a two-layer cup or pot, and the gap space A3 is evacuated in order to provide heat retaining and heat insulating effects. Since this gap space A3 does not have any heat conduction medium inside in a vacuum state, internal heat is not conducted to the outside, and a heat retaining effect can be achieved.

  2a and 2b show a two-layer container having another configuration in the prior art. As shown in these drawings, FIG. 2a shows that the two-layer container B has a gap space B3 between the inner wall surface B1 and the outer wall surface B2, but the bottom B4 is not sealed. Is adopted. The outer wall surface B2 is extended and cut to align with the bottom B4 of the two-layer container B, and the one shown in FIG. 2b is also a gap space C3 between the inner wall surface C1 and the outer wall surface C2 of the two-layer container C. However, the bottom C4 is not sealed. The outer wall surface C2 is extended and exceeds the bottom C4 of the two-layer container C. Each of these two-layer containers A, B, and C has a two-layer structure, but the temperature of the cold / hot liquid put inside is difficult to be transmitted to the outer wall surfaces A2, B2, and C2 even when touched by hand. In addition, since the outer wall surfaces A2, B2, and C2 limit the extension of the inner wall surfaces A1, B1, and C1 to the outside, and the two are separated by the gap spaces A3, B3, and C3, The internal volume of the structure of each bilayer container A, B, C will be much smaller compared to a typical single layer container of the same outer diameter.

  When the above-described conventional two-layer container employs stainless steel, a cup or pot is manufactured in a two-layer structure by a drawing method. The metal drawing process is a manufacturing method used for hollow seamless tubes and container-like materials.

  In addition, when a glass material is used for manufacturing a two-layer container, a two-layer structure is manufactured by adopting a glass blowing method, and then the bottom of the two-layer container is sealed, and in particular, a two-layer container A is manufactured. . Moreover, in order to ensure that there is no heat conduction medium in the gap space of the two-layer structure regardless of stainless steel or glass, both of them need to be subjected to vacuum treatment in order to achieve the effect of heat insulation and heat retention. Vacuum processing is a complicated manufacturing process, and the manufacturing cost is significantly increased. If the vacuum step is not completely evacuated, the heat insulation and heat insulation effects cannot be achieved. Therefore, the conventional two-layer structure has a large number of processes and a higher manufacturing cost than a single container. Become.

  In addition, since the conventional two-layer container has a heat insulating structure as a whole, when the two-layer container is used as a cup and liquid is put inside, the inside of the two-layer container is visually cool or hot liquid It is not possible to confirm whether the liquid in the two-layer container is cold or hot. However, this method may cause burns, and there is a problem that it is unsanitary to directly touch the liquid by hand.

  In addition, in order to manufacture a container having a two-layer structure, the capacity of the inside thereof is reduced. Compared with one container having the same outer diameter, the inner capacity of one container is reduced because of the two-layer structure. It must be less than the content.

Therefore, the problems of the above-described conventionally known two-layer container are summarized as follows.
1. Manufacturing cost is high.
2. The temperature of the contents is difficult to understand from the outside.
3. The internal volume is small.

  In order to achieve the above-described object, the two-layer container of the present invention includes a main body, the main body includes a first portion, and the upper end portion of the first portion is folded outwardly to form a second portion. The first part has a bottom and an opening, the second part has an upwardly extending free end facing the bottom of the first part, and between the first part and the second part. By forming the first space. It solves the problem.

  By designing the upper surface of the two-layer container with a two-layer wall design, not only can material and manufacturing costs be saved, but when the user puts cold or hot water into the container, the contents can be touched by touching the lower side of the main body. By knowing the temperature of the object and touching the contents (liquid) directly, you can prevent your fingers from getting wet or burning your fingers, and at the same time open the first space to the outside By providing them, convection can be generated and the second part can have a heat insulating effect.

That is, the two-layer container of the present invention has the following advantages compared to the two-layer container of the prior art.
1. Easy to manufacture.
2. Cost can be saved.
3. The internal volume is relatively large.
4. Know the temperature of the contents by touching the first part.
