Negative pressure type self-mixing double-agent packaging bottle

Abstract

The invention discloses a negative pressure type self-mixing double-agent packaging bottle, and relates to the technical field of cosmetic packaging. The negative pressure type self-mixing double-agent packaging bottle comprises a bottle body; the top end of the bottle body is sleeved with a top cap, and the bottom of the bottle body is provided with a bottom cap; a connector is also arranged between the bottle body and the top cap; a small stock bin is further arranged in the connector; the bottom of the connector is also connected with a stirring rod; and the small stock bin can be driven by the rotation of the top cap to move up and down relative to the connector. The invention provides a negative pressure type self-mixing double-agent packaging bottle, which is simple in structure, convenient to use and capable of effectively realizing independent partitioned storage of two types of cosmetic components with different characters, so that storage and transportation of cosmetics are facilitated, the overall shelf life and service life are prolonged, two kinds of cosmetics can be automatically mixed in the actual use process, and operation is very convenient; the problem of squeezing and splashing is avoided by adopting a negative pressure type mixing mode; and high-viscosity liquid can be effectively mixed.

Description

technical field [0001] The invention relates to the technical field of cosmetic packaging, in particular to a negative-pressure self-mixing double-dose packaging bottle. Background technique [0002] Cosmetics refer to smearing, spraying or other similar methods that are spread on any part of the human body surface, such as skin, hair, nails, lips and teeth, etc., to achieve cleaning, maintenance, beauty, modification and change of appearance, or to correct human body odor, maintain Chemical industrial products or fine chemical products for the purpose of good condition. [0003] Most of the double-dose packages used in the prior art are push-type double-dose, which allows positive pressure to be generated in the cavity. This method is easy to spray liquid, and it is not easy to mix high-viscosity materials. Contents of the invention [0004] The purpose of the present invention is to solve the defects in the prior art, and propose a negative pressure self-mixing double-d...
