[ description of the drawings ]
Fig. 1 is a sectional view of a cosmetic packaging bottle and a manufacturing process thereof according to the present invention.
In the figure: 1-bottle inner blank, 2-electroplated layer and 3-bottle outer shell.
[ detailed description ] embodiments
Referring to fig. 1, the bottle comprises a bottle inner blank 1, an electroplated layer 2 and a bottle outer shell 3, wherein the electroplated layer 2 is electroplated outside the bottle inner blank 1, the bottle outer shell 3 is injection-molded outside the electroplated layer 2, the thickness of the bottom of the bottle outer shell 3 is larger than that of the edge of the bottom, and an injection-molded shrinkage port is arranged in the center of the bottom of the bottle outer shell 3.
Specifically, the bottle inner blank 1 is a hollow circular shell, and the bottle outer shell 3 is a hollow circular or hollow square shell.
The invention also comprises a manufacturing process thereof, which comprises the following steps:
the method comprises the following steps: forming a bottle inner blank 1 by using a raw material I in an injection molding or casting mode;
step two: electroplating the bottle inner blank 1 to form an electroplated layer 2 on the outer surface of the bottle inner blank 1;
step three: and (3) arranging the bottle inner blank 1 with the electroplated layer 2 into an injection mold, and injecting a second raw material to form a bottle shell 3 outside the electroplated layer 2 in a secondary injection molding mode.
