Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum lotion bottles, and in particular relates to a double-layer vacuum lotion bottle. Background Art

[0002] A vacuum lotion bottle is a container that uses vacuum technology to store lotions. The lotion stored in the vacuum lotion bottle can be isolated from the air to prevent the product from oxidizing and deteriorating due to contact with the air, breeding bacteria, etc. The vacuum lotion bottle consists of a cylindrical or ellipsoidal container, a piston arranged on the bottom surface of the bottle body, and a lotion pump installed at the bottle mouth. Its design principle is to form a negative pressure at the bottle mouth by pressing the vacuum pump, and then use the atmospheric pressure to push the piston at the bottom of the bottle toward the bottle mouth, so that the lotion stored in the bottle is squeezed out from the bottle mouth. Today's vacuum lotion bottles are divided into inner liner bottles and outer liner bottles. Such inner liner bottles and outer liner bottles are generally connected to the top pressing seat through buckles, and the buckle connection method is also more troublesome to disassemble, which affects the convenience of secondary use of the vacuum lotion bottle.
