Abstract

A thermal and cold insulation bottle structure is disclosed herein, comprising: a bottle body having an integrally formed stainless steel double wall, an opening, an interior space, and a base portion, wherein the opening having an inner wall disposed with a female thread; a lid having a male thread corresponding to the female thread to screw on the opening of the bottle body; and a removable bottom cover having an expandable plug, a screw secured to the center of the expandable plug, a nut engaged with the screw, and a lever connected to the nut, so as to allow the removable bottom cover to be accommodated in the base portion of the interior space of the bottle body.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a thermal and cold insulation bottle structure. It mainly comprises a bottle body and a special removable bottom cover for fittingly accommodating various beverage bottles with different heights, e.g. beer bottles and soft drink bottles, so as to prevent arbitrary movements of the beverage bottle in the thermal and cold insulation bottle structure and to keep beverage inside the beverage bottles cold or hot during drinking without the need of taking out the beverage bottles from the thermal and cold insulation bottle structure.2. Description of Related Art[0002]In order to maintain an original flavor and an icy cold taste of beverage, e.g. beer or soft drink, various beverage housings, containers or receptacles have been designed to directly accommodate the beverage bottle in its internal space for continuously keeping the beverage cold or hot without pouring out the liquid from the beverage b...

Benefits of technology

[0008]According to an embodiment of the present invention, the lid, or the removable bottom cover, or both can be made of a plastic material, and the male thread of the lid is made of a flexible plastic material, e.g. silicone, rubber, foam material, injecting soft material and the like. In such a case, the tightness of the whole structure can be increased when the removable bottom cover and the lid are respectively locked

Problems solved by technology

However, the abovementioned structures do not cover the beverage bottle completely, so that the effect of thermal and cold insulation is still limited.

Moreover, in drinking the beverage, users
