Abstract

The invention discloses a pressing type make-up pen cap. The key points of the technical scheme are as follows: the pressing type make-up pen cap comprises a hollow-tube-shaped body and an end plate arranged at one end of the body, wherein first clamping and embedding parts being close to the opening of the body and used for clamping the head of a make-up pen are arranged on the inner side wall ofthe body. The pressing type make-up pen cap is characterized in that a plurality of locating blocks positioned in the inner cavity of the body are arranged on the end plate, and the locating blocks are distributed at equal intervals around the axis of the body; an elastic soft plug is arranged in the body, and locating grooves for clamping in the locating blocks are formed in the elastic soft plug; and an inserting hole for inserting the tail end of the head of the make-up pen is formed in the end face, deviating from the end plate, of the elastic soft plug. The make-up pen cap provided by the invention has the effects of inhibiting the volatilization of the active ingredients of cosmetics, retarding oxidative deterioration and isolating bacterium contamination. The invention further correspondingly discloses a manufacturing method of the pressing type make-up pen cap, the manufacturing method comprises the steps including soft plug forming, pen cap forming, assembly and hot pressing,and the manufactured pen cap has the advantages of being safe and sanitary, and being durable in use.

Description

technical field [0001] The present invention relates to the technical field of cosmetic pencil and its manufacture, more specifically, it relates to a push-type cosmetic pencil cap and its manufacturing method. Background technique [0002] The Chinese Patent Application Publication No. CN108991706A discloses a multi-color pressing cosmetic pen, which includes a pen body, a nib arranged at the end of the pen body and a cover for protecting the nib. The tip of the makeup pencil is thinner, and the inner diameter of the cap is much larger than the diameter of the tip. Therefore, after the cover is sleeved on the nib, there is a large gap between the lid and the nib. On the other hand, for the convenience of use, the conventional lid is only fixed by snap-fitting after closing, and the sealing performance is relatively poor, so that after the lid is closed, not only a large amount of air remains inside but also the inside and outside are connected, which is easy to cause the b...

Therefore, after the cover is sleeved on the nib, there is a large gap between the lid and the nib.

On the other hand, for the convenience of use, the conventional lid is only fixed by snap-fitting after closing, and the sealing performance is relatively poor, so that after the lid is closed, not only a large amount of air remains inside but also the inside and outside are connected, which is easy to cause the bioactive ingredients in cosmetics, such as Proteins, plant extracts, etc. are oxidized and deteriorated or contaminated by bacteria, which will have an adverse effect on the long-term storage of cosmetics in the cosmetic pen
