Embodiment Construction

[0021] refer to figure 1 , the present invention comprises a bottle inner embryo 1, an electroplating layer 2 and a bottle shell 3, the electroplating layer 2 is electroplated on the outside of the bottle inner embryo 1, and a bottle shell 3 is injection-molded on the exterior of the electroplating layer 2, and the thickness of the bottom of the bottle shell 3 is greater than that of the bottom The thickness of the edge, the bottom center of the bottle shell 3 has an injection shrinkage port.

[0022] Specifically, the bottle inner embryo 1 is a hollow circular shell, and the bottle shell 3 is a hollow circular or hollow square shell.

[0023] The present invention also includes its manufacturing process, comprising the following steps:

[0024] Step 1: forming the inner embryo 1 of the raw material 1 by injection molding or casting;

[0025] Step 2: Electroplating the bottle inner embryo 1 to form an electroplating layer 2 on the outer surface of the bottle inner embryo 1; ...

Abstract

The invention discloses a cosmetic packaging bottle which comprises a bottle inner blank, an electroplated layer and a bottle shell. The electroplated layer is electroplated outside the bottle inner blank, the bottle shell is arranged outside the electroplated layer in an injection molding manner, the thickness of the bottom of the bottle shell is larger than that of the edge of the bottom, and an injection molding shrinkage opening is formed in the center of the bottom of the bottle shell. The invention further discloses a manufacturing process of the cosmetic packaging bottle. The manufacturing process is characterized by comprising the following steps that firstly, the bottle inner blank is formed by a first raw material in an injection molding or casting manner; 2, the bottle inner blank is electroplated, and the electroplated layer is formed on the outer surface of the bottle inner blank; and 3, the bottle inner blank with the electroplated layer is placed in an injection mold, a second raw material is injected, and the second raw material forms the bottle shell outside the electroplated layer in a secondary injection molding manner. According to the cosmetic packaging bottle, through a new architectural feature that the thickness of the bottom of the bottle shell is larger than that of the edge of the bottom, in cooperation with the secondary injection molding process, the novel cosmetic bottle with the electroplated layer clamped inside is obtained.

Description

【Technical field】 [0001] The invention relates to the technical field of cosmetic packaging bottles, in particular to the technical field of a manufacturing process of a new cosmetic packaging bottle. 【Background technique】 [0002] A cosmetic bottle refers to a container that can isolate the contents from the outside world or isolate external bacteria. There are many types of cosmetic bottles, and cosmetic bottles are usually formed by injection molding and then combined again. In order to be more beautiful, a layer of electroplating will be electroplated on the outside of the bottle inner embryo, and then the inner embryo and the outer shell of the bottle will be bonded together. However, glue is needed for bonding, and the amount of glue is often not well controlled. This will cause the adhesive layer to loosen during repeated opening and closing of the bottle, thereby separating the inner and outer layers. For this reason, need a kind of new manufacturing process, can...
