Description

Bottle cap convenient to process

Technical Field

The utility model relates to a field of bottle lid particularly, relates to a bottle lid of convenient processing.

Background

The bottle cap is a sealing device of a wine bottle and is also a decoration device of wine bottle packaging. In fact, the bottle cap has various forms, so that the whole wine bottle is attractive and elegant. There is a bottle cap including an inner cap and an outer cap. The outer cover is provided with a cylindrical inner cover accommodating cavity. One end of the inner cover accommodating cavity is open, and the other end is closed. The inner wall of the inner cover accommodating cavity is provided with a limiting bulge. The inner cover is provided with a limit groove. After the inner cover is placed in the inner cover accommodating cavity, the limiting protrusion is accommodated in the limiting groove, so that the inner cover is tightly connected with the outer cover, and the inner cover is prevented from falling off in use.

Because the limiting bulge is arranged on the inner wall of the inner cover accommodating cavity, when the outer cover is subjected to injection molding, the mold can only be separated from the inner cover accommodating cavity from one end of the opening of the inner cover accommodating cavity. After the injection molding is finished, the limiting bulge prevents the mold from being directly pulled out of the inner cover accommodating cavity, and the mold needs to be ejected in an inclined ejection mode. This makes the mold complicated in structure, increases the cost of mold production, and also increases the cost of outer cover production.

Example 1:

referring to fig. 1 to 6, the present embodiment provides a bottle cap that is convenient to process, and includes an outer cap 200 and an inner cap 100. The outer cap 200 is provided with a cylindrical inner cap receiving chamber 210. The inner cap receiving chamber 210 has an open end and an end cap 212 at the other end. The end cap 212 serves to limit the inner lid 100 from falling off the inner lid 100. The end cap 212 is provided with 3 through mold holes 213 along its circumference and the 3 through mold holes 213 are evenly distributed. The inner wall of the inner cap receiving cavity 210 is provided with 3 limiting protrusions 211. The 3 limit protrusions 211 are respectively distributed at one through hole 213 of the mold. The outer wall of the inner lid 100 is provided with a stopper groove 110 in cooperation with the stopper protrusion 211. The outer diameter of the inner cap 100 is slightly smaller than the inner diameter of the inner cap receiving cavity 210 so that the inner cap 100 can be received in the inner cap receiving cavity 210. After the inner cap 100 is received in the inner cap receiving cavity 210, the limit protrusion 211 is received in the limit groove 110, such that the inner cap 100 and the outer cap 200 are tightly connected to prevent the inner cap 100 and the outer cap 200 from being separated.

The utility model discloses an enclosing cover 200 of bottle lid adds man-hour, needs to use two moulds of mutually supporting. After the two molds are combined, an injection molding cavity of the limiting protrusion 211 can be formed between the two molds. One end of the inner cover accommodating cavity 210 is open, and the other end is provided with an end cover 212; the end cap 212 is provided with a plurality of through holes 213 along the circumference thereof, and the limiting protrusions 211 are respectively distributed at one through hole 213. When the outer cover 200 is processed, the injection molding cavity of the limiting protrusion 211 is located at the through hole 213 of the mold, after the injection molding is completed, one mold is separated from the inner cover accommodating cavity 210 from the open end of the inner cover accommodating cavity 210 along the inner wall of the inner cover accommodating cavity 210, and the other mold is separated from the inner cover accommodating cavity 210 from the through hole 213 of the mold along the inner wall of the inner cover accommodating cavity 210; namely, the two molds move in opposite directions to smoothly discharge the mold.

Need be through the mode demolding of pushing up to one side for current enclosing cover 200 processing, the utility model discloses an enclosing cover 200 of bottle lid avoids adopting the mode demolding of pushing up to one side for mould simple structure reduces the manufacturing cost of mould and enclosing cover 200's manufacturing cost. Meanwhile, the die is simple in structure, so that the practical service life of the die is longer.

The bottle cap is provided with a plurality of through-mold holes 213, which also results in less raw material required for manufacturing the outer cap 200, saving raw material.

Further, the edge of the through hole 213 extends to the inner wall of the inner cap receiving cavity 210. So that the wall of the through-mold hole 213 and the inner wall of the inner-cap receiving cavity 210 are in the same plane. When the mold is separated from the inner cap receiving cavity 210 from the mold through hole 213 along the inner wall of the inner cap receiving cavity 210, the mold can be smoothly pulled out from the mold through hole 213, and the mold is prevented from being blocked and not pulled out.

Further, the side wall of the inner cap receiving cavity 210 has 3 notches at one end close to the end cap 212. Each of which is connected to one of the through mold holes 213. The end cap 212 is provided with 3 through holes 213 of the mold, and the sidewall of the inner cap receiving cavity 210 is provided with 3 notches, which greatly reduces the raw materials required for the production of the outer cap 200 and saves raw materials.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
