Non-plastic container for storing food
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.
1 . A food storing container formed of a non-plastic container body formed of glass, stainless, ceramic ware, etc., and a plastic lid formed of plastic, a food storing container having a non-plastic container body, comprising:
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.
2 . The container of claim 1 , wherein the plastic rim is inserted into and engaged to an outer portion of the container body with a certain tensional force.
3 . The container of claim 1 , wherein the plastic rim is formed based on a double injection method in a state that the container body is inserted into a plastic injection molding.
4 . The container of either claim 2 or 3 , wherein an engaging groove is formed on an outer surface of the upper side of the opening of the non-plastic container body for enhancing an engaging force with the plastic rim.
5 . The container of either claim 2 or 3 , wherein when forming the plastic rim in the container body based on the double injection method, a plastic coating layer is integrally formed with the plastic rim wherein the plastic coating layer surrounds the outer surface and lower portions of the container body.
