Description

Container to prevent dropping and manufacturing method thereof {CONTAINER FOR PREVENTING FALLOUT AND METHOD FOR MANUFACTURING THE SAME}

The present invention relates to a container (tableware, bowl), and more particularly, to a container for preventing double dropping and a method for manufacturing the same.

In general, a container used for storing or washing food and used as a container is made of a synthetic resin material or a metal material, and is formed to prevent deterioration and contamination of food and preserve it for a long time.

Moreover, the container formed of the double structure has the advantage of being able to maintain the heat retaining power of the content for a long time, and the heat transfer of the content to the outside is slow, so that the user can easily hold the outside of the food container and transport it easily.

However, such a double-formed container may be manufactured using a compression method or an insert method.

First, a method of manufacturing using a compression method may be formed to press the inner and outer containers of different sizes, and then weld the outer peripheries of the inner and outer containers to minimize the transfer of heat from food to the outside. However, in this case, as the welding process for manufacturing the container requires skill, the work efficiency is lowered and the work productivity is reduced.

Moreover, the expansion or contraction of the container is repeated according to the difference between the food temperature and the external temperature, so that a gap is generated between the containers and water enters or separates the containers during the washing process.

As another method, it may be manufactured using an insert method, which is manufactured by coating the outer container on the outer surface of the inner container, and has a disadvantage in that durability is deteriorated by the properties of the material constituting the container.

Looking at the background technology to compensate for this problem, as shown in Figure 1, Republic of Korea Registered Utility Model Publication No. 20-0198783 (hereinafter referred to as'document 1') "multi-layer molded tableware" in the outer peripheral surface of the inner cylinder Disclosed is a container containing a plurality of protrusions so that separation can be prevented.

In the case of using the invention of Document 1, there is an advantage that the inner and outer cylinders are completely combined by a simple process, but water is introduced into a portion where projections are not formed by frequent washing, thereby causing mold or scale to deteriorate the durability of the container. There is this.

Looking at the other background technology, as shown in Figure 2, Republic of Korea Patent Publication No. 10-2017-0094956 (hereinafter referred to as'document 2') "color of different bowls double injection method and the double injection produced by the method Bowl”, discloses a bowl manufactured by a double injection method having different colors including an engaging portion by forming irregularities on the inner surface of the inner mold.

When using the invention of Document 2, there is an advantage that can prevent the phenomenon of the separation between the inner body and the outer body, there is a disadvantage that the durability is reduced or separated over time by the material of the vessel is formed in the form of injection.

Looking at the other background technology, as shown in Figure 3, in the "food container" of the Republic of Korea Registered Utility Model Publication No. 20-0263985 (hereinafter referred to as'document 3'), by inserting a rubber ring between the bends of the outer container, Disclosed is a food container formed to prevent corrosion of the container by completely blocking the penetration of moisture and water into the space portion of the inner and outer containers.

In the case of using the invention of Document 3, the penetration of moisture and water into the space of the inner and outer containers due to the airtightness of the rubber ring as it is manufactured by pressing (pressing) while inserting the rubber ring between the inner and outer container parts There is an advantage that can prevent the corrosion of the container by blocking, there is a disadvantage that the internal and external containers are separated due to gaps as the container expands and contracts due to the difference between the food temperature and the external temperature.

Looking at the other background technology, as shown in Figure 4, in the "double container and its manufacturing method" of Republic of Korea Patent Publication No. 10-1101876 (hereinafter referred to as'document 4'), to have a space portion by combining with the inner container Disclosed is a double container in which a space portion is formed between an outer container and an inner container by being fused by supply of the inner container to an upper inner diameter of the outer container having a separation guide protrusion.

In the case of using the invention of Document 4, the outer container having the spacer guide protrusion and the inner container having a predetermined storage space are combined to form a welded and fixed integrally by fusion at the inner diameter of the protruding jaw of the inner container, thereby providing the contents by a double structure. There is an advantage that can block the temperature of the transfer to the outer container, there is a hassle that it is necessary to further perform a precise process by fixing by welding.
