Volume-variable bottle

Abstract

The invention discloses a volume-variable bottle. The bottle comprises a bottle body, a bottle bottom and a bottle cap, and the bottle cap is detachably connected with the top end of the bottle body; the bottle bottom comprises a chock plug, the side wall of the chock plug is connected with the inner wall of the bottle body in a sliding mode, and the chock plug abuts against the bottle body; a sealing rubber ring is arranged between the chock plug and the bottle body, and the sealing rubber ring is fixedly connected with the chock plug; and a plurality of limiting check blocks are fixed to the bottom end of the inner wall of the bottle body in the circumferential direction at equal intervals, the number of the limiting check blocks is not less than two, and the bottom end of the chock plug matches the limiting check blocks in a limiting mode. According to the bottle, the thought that the bottle body and the bottle bottom are separated is adopted for the bottle with the fixed volume, so that the volume of the bottle is variable, and the risk that a half bottle of solution after use is oxidized and infected with microorganisms is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a variable volume bottle. Background technique [0002] At present, the hard packaging bottles used in the market are all fixed volumes, such as 500ml, 750ml, 1000ml, 2000ml, 5L, 10L, etc. In many cases, once the bottle is produced, the volume is fixed and cannot be changed. [0003] Many food liquids are easily oxidized, resulting in sensory and nutritional changes. In addition, microorganisms are prone to grow and cause mold when exposed to air, such as wine, fruit juice, and vegetable oil. They must be eaten as soon as possible after the first opening, otherwise they will deteriorate. If it changes, it will become moldy and inedible. [0004] However, the existing vegetable oils, wines, and fruit juices on the market are all packed in fixed-volume bottles. When they can’t be used up at one time, they can only be stored in half of the original bottle. Signs of oxidatio...

Problems solved by technology

[0002] At present, the hard packaging bottles used in the market are all fixed volumes, such as 500ml, 750ml, 1000ml, 2000ml, 5L, 10L, etc. In many cases, once the bottle is Once produced, the volume is fixed and cannot be changed

[0003]Many food liquids are easily oxidized, resulting in sensory and nutritional changes. In addition, microorganisms are easy to breed and cause mold after contact with air, such as wine, fruit juice, and vegetable oil. It must be eaten as soon as possible, otherwise it will deteriorate, ranging from changes in sensory and nutrition, to moldy and inedible

[0004] However, the existing vegetable oil, wine and fruit juice on the market are all packed in fixed-volume bottles. Stored in a bottle, when you eat it again, there will be more or less signs of oxidation, which will affect the sensory perception and nutrition
