Seal jar

Abstract

A seal jar is constituted by a jar body collocating with an inner jar inserted into the jar body and a lid. An annular protruding rim in stair shape is formed on the upper end edge of the inner jar, and an annular groove corresponding to the lower end of the protruding annular rim for fitting with a seal is formed on the side edge of the inner jar which is covered by the lid which has a seal on the lid edge. The inner jar is inserted in the jar body, and the seal fitted in the annular groove of the inner jar seals at the inner side of the jar body. The lid fits at the upper end of the annular protruding rim of the inner jar, and the seal fitted in the annular groove of the lid similarly seals at the inner side of the annular protruding rim.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a seal jar, particularly to a novel seal jar capable of remarkably reducing total space taken by seal jar used, having more diversified collocation in use, and capable of increasing more practical value in its total implementation thereof.[0003]2. Brief Description of Prior Art[0004]Water molecules contained in air often causes deterioration, decay or even mildewing of food. As food, seasoning or additive is often impossible to be used up at one time, how to preserve or keep these stuffs fresh has become an important issue which needs to be settled by people. Usually only capacity of accommodation is usually emphasized on container for receiving stuff and refrigerator is used to keep things fresh, but not all foods are suitable to be preserved in refrigerator. Therefore, a seal jar is proposed to separate the food from air, so as to prevent food from deteriorating, wetting or to keep food away ...
