Description

Emulsion bottle

Technical Field

The utility model belongs to the technical field of the cosmetics packaging technique and specifically relates to a lotion bottle is related to.

Background

The liquid cosmetic is usually kept in a glass bottle and a little is taken out as needed when needed. In order to control the amount of use and reduce waste, a manually pressed pressure pump may be used to draw the liquid cosmetic. In order to prevent cosmetics from seeping from a gap between the pressure pump and the bottle body, most manufacturers can arrange a gasket for reinforcing the sealing between the pressure pump and the bottle body, and although the sealing effect is ensured by adding the arranged sealing gasket, the assembly process of the product is increased, and the production efficiency is reduced.

Preferably, an annular connecting sheet is arranged in the middle of the inner wall of the through mounting hole of the connecting piece, and the sealing collar extends downwards from the lower surface of the annular connecting sheet. The sealing collar may also extend directly from the side wall of the connection piece, but the structure of the sealing collar is simplest when it extends downwards from the lower surface of the annular web.

In order to enhance the stability between the pressing liquid taking assembly and the connecting piece, preferably, the upper surface of the annular connecting piece is provided with a snap ring connecting piece which extends upwards and is used for being connected with the pressing liquid taking assembly.

In order to provide a yielding space for pressing the cap, preferably, a gap is formed between the snap ring connecting sheet and the inner wall of the through mounting hole.

In order to facilitate the connection of the connecting piece and the bottle body, preferably, an internal thread is formed on the inner wall of the lower side of the through mounting hole of the connecting piece, an external thread is formed on the outer wall of the bottle mouth, and when the connecting piece is connected with the outer wall of the bottle mouth, the bottle mouth is inserted into the through mounting hole of the connecting piece and is fixedly connected with the inner wall of the lower side of the through mounting hole through threads.

In order to prevent the pressing liquid taking component from being pressed by mistake, the bottle cap is preferably further included, and the bottle cap can be sleeved outside the pressing liquid taking component and is buckled with the connecting piece.

Preferably, the connector is externally formed with a step for abutment with the bottom of the cap.

Preferably, the liquid component is got in pressing includes from the top down connect gradually according to cap, pump core subassembly, the pump body and burette, and the upper end sealing connection of burette is on the pump body, and pump core subassembly sealing connection is inside the pump body, and outside sealing connection of the pump body is in the through-going mounting hole of connecting piece. In another technical scheme, the pressing liquid taking assembly is a vacuum liquid taking structure without a dropper.

Compared with the prior art, the utility model has the advantages of: the sealing collar replaces a gasket to realize the sealing effect, so that the production cost can be reduced, and the assembly is convenient; and the outer side wall of the sealing collar can be in interference fit with the inner side wall of the bottle mouth, and when thermal expansion and cold contraction occur, the sealing effect can be ensured.
