Description

Storage container {STORAGE CONTAINER}

The present invention relates to a storage container, and more specifically, to a storage container that prevents changes in the quality of the paint by improving the airtightness of the paint stored for paint work.

In general, various liquid contents, such as food ingredients such as cooking oil or beverages, or industrial materials such as lubricants, paints, and thinners, are filled in containers and then sealed and transported with lids, and the lids can be opened when used. If there are any contents remaining, the lid is tightly closed on the container to prevent deterioration and coagulation.

In particular, steel paint containers and packaging containers are used to store and stir paints for specific purposes, such as paints.

A steel paint container consists of a container body, a coupling ring, and a cover. The coupling ring is coupled to the container body through a shimming method, and the cover is installed on the coupling ring in an open/closed manner.

Steel paint containers can be used with paint after opening the cover, and the cover can be rejoined to the coupling ring, but there is a problem of corrosion by components or gases in the paint.

A packaging container is made up of a container body and a cover, and the cover is formed integrally with the container body by an undercut. The undercut can be cut from the cover and container body before applying paint.

The packaging container is prevented from corrosion by paint components or gases, but if the undercut is cut off, airtightness cannot be maintained even when the cover is closed, making reuse of the paint almost impossible.

For this purpose, paint containers have been proposed in the past where the container body is made of a synthetic resin material and the cover is made of a metal material. However, it is impossible to prevent rust that may occur during long-term storage of the paint, and because it has a bonding structure of different materials, Separation and disposal for recycling were inconvenient.

Therefore, there is a need to improve paint storage containers to solve this problem.

The background technology of the present invention is disclosed in Republic of Korea Registered Utility Model Publication No. 20-0230622 (published on December 15, 1999, title of the invention: Paint container for preventing paint from dripping).

It is manufactured from plastic materials such as nitrile (AN), polycarbonate (PC), polyamide (nylon), or a blow molding process such as a reheat stretch blow molding process.

The storage container 100 may be made of an insulating material of thermoplastic elastomer (TPE) to have insulation performance.

Thermoplastic elastomers have the properties of both rubber and plastic, but are harder than rubber and have greater resilience than plastic, so they are resistant to various interferences that may occur from surrounding equipment at the work site during paint work using the storage container 100. It can respond flexibly and is convenient to handle, reducing work time and procedures.

The storage container 100 can be configured with an insulating coating method by using insulating materials such as silicone, rubber, and synthetic resin. Insulating materials such as silicone, rubber, and synthetic resin are poured with a solvent using a mold (molding mold) and inserted. It can be manufactured by casting method.

The material of the storage container 100 can be made of silicone, rubber, and synthetic resin for insulation. It is not limited to a specific material, and the storage container 100 can be easily constructed and implemented in various ways as long as it is made of a material with excellent insulation properties. do.

As a result, the storage container 100 of the embodiment according to the present invention has a container body portion 110 and a cover portion 130 made of plastic material, thereby preventing rust, thereby providing an eco-friendly effect that is stable and easy to recycle. Since airtight sealing force and coupling force are implemented through the first fastening portion 113 of the container body 110 and the second fastening portion 131 of the cover portion 130, the The paint can be reused and stirred.

The first fastening portion 113 includes a fused end portion 112, a first fastening protrusion 114, and a second fastening protrusion 116, and the second fastening portion 131 includes a hook body 131a and a first stumbling block. By providing the group 131b and the second locking protrusion 131c, airtightness of the paint is quickly secured with a single pressurization between the first fastening part 113 and the second fastening part 131, thereby ensuring good quality of the paint. It can be maintained.

The storage container 100 has a binding protrusion 117 formed at the bottom of the container body 110, and a binding groove 130a is formed at the top of the cover 130, thereby forming a plurality of container body parts 110. Since it implements stacking storage, it has the effect of increasing handling in spaces where paint containers are stored in large quantities.
