Non-plastic container for storing food

Abstract

The present invention relates to an improved non-plastic container for storing food in which a lid fabricated using plastic based on an injection molding method is sealingly engaged to a non-plastic container body formed of a heat resisting glass, a stainless material, a heat resisting ceramic ware, etc. The food storing container having a non-plastic container body comprises a closed ring shaped plastic rim formed in an upper side of an opening of the non-plastic container body wherein the closed ring shaped plastic rim surrounds all outer surrounding portions of the container body; and at least more than locking protrusion integrally formed at the opposite sides of the plastic rim wherein the locking protrusions are inserted into locking holes formed in locking wings of the plastic lid.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a non-plastic container for storing food, and in particular to an improved non-plastic container for storing food in which a lid fabricated using plastic based on an injection molding method is sealingly engaged to a non-plastic container body formed of a heat resisting glass, a stainless material, a heat resisting ceramic ware, etc. [0003] 2. Description of the Background Art [0004] Generally, a container body of a container capable of storing foods is formed of a plastic material approved for storing foods, a heat resisting glass, a heat resisting ceramic ware, a stainless, etc. A lid detachably engaged to an opening of a container body formed of the above material is generally formed of a plastic material. [0005] The plastic lid has a certain engaging structure capable of sealing engaging an opening of a container body for stably storing foods stored in the container body. Recentl...

AI Technical Summary

Benefits of technology

[0013] It is another object of the present invention to provide a non-plastic container for storing food capable of enhancing an engaging force between a non-plastic container body formed of glass, stainless, ceramic ware, etc. and a plastic lid for thereby largely increasing a sealing property therebetween. In addition, it is possible to stably store foods based on a high strength and high heat-resisting property of a container body.

Problems solved by technology

However, it is impossible to form any protrusion in the container body formed of a heat resisting tempered glass, stainless or heat resisting ceramic ware that is a non-plastic material, the lid having the locking wing is not adapted to the non-plastic container body.

Therefore, in the case of glass, it has a melting point largely higher than the melting point of the plastic, and it is impossible to obtain a desired flexibility in a melted state, the injection molding is impossible as compared to the plastic product.

In addition, a mass production is impossible.

It is impossible to form a complicated shape having a thin thickness at an outer surface of the product.

In the case that there is a large thickness difference in the glass product, the product may be broken or may have cracks during a cooling process after molding by a contraction difference during the cooling process.

However, a molding property is very bad due to its high strength.

It is impossible to form a product having protrusions.

Therefore, in the cases of the non-plastic container body formed of glass, stainless material or ceramic ware and the plastic lid formed by the injection molding method, the engaging method of the locking hole and the locking protrusion is not adapted.

However, since the engaging protrusion 205 is engaged to the engaging shoulder by an elastic recovering force of the extension part 204 itself, the engaging force is weak, and the lid 200 is pulled in the direction of the container body 100, so that it is impossible to obtain a desired sealing force.
