Abstract

The utility model discloses a self-retreating type replacement bottle, which relates to the technical field of replacement bottles, and comprises an outer bottle and a bottle cap, wherein the bottle cap is sleeved on the top of the outer bottle, an inner bottle is arranged in the outer bottle, the inner bottle extends to the top of the outer bottle, a screw cap is sleeved on the top of the inner bottle, the screw cap is connected with the inner bottle through threads, the screw cap is sleeved on the top of the outer bottle, the outer bottle is connected with the screw cap through interference fit, the screw cap is connected with the inner bottle through threads, then the screw cap is clamped on the outer bottle, and when the inner bottle is replaced, the screw cap is only required to be unscrewed, the screw cap is separated from the outer bottle by upward movement due to the reaction force of the inner bottle, so that the inner bottle can be taken out and replaced conveniently and quickly, the difficulty of replacing the inner bottle is small, and the bottle is very convenient to use.

Description

Self-retreating type replacement bottle

Technical Field

The utility model relates to the technical field of replacement bottles, in particular to a self-retracting type replacement bottle.

Background

At present, most of cosmetic bottles on the market cannot be replaced, but can be used once, and on the premise of global advocating of environmental protection, some cosmetic bottles are provided with inner bottles, but the inner bottles are difficult to take out and replace, and are also directly discarded, so that the cosmetic bottles are very inconvenient to use.

Disclosure of Invention

The utility model provides a self-retracting type replacement bottle to solve the technical problems.

In order to solve the technical problems, the self-retreating type replacement bottle comprises an outer bottle and a bottle cap, wherein the bottle cap is sleeved at the top of the outer bottle, an inner bottle is arranged in the outer bottle and extends to the top of the outer bottle, a screw cap is sleeved at the top of the inner bottle, the screw cap is connected with the inner bottle through threads, the screw cap is sleeved at the top of the outer bottle, and the outer bottle is connected with the screw cap in an interference fit manner.

Preferably, a piston is arranged in the inner bottle, and the bottom end of the inner bottle is connected with a bottom bracket through threads.

Preferably, the outer end of the inner bottle is provided with a limit flange, and the limit flange is matched with the inner part of the outer bottle.

Compared with the related art, the self-retreating type replacement bottle provided by the utility model has the following beneficial effects:

through with screw shell lid and interior bottle threaded connection together, later with screw shell lid joint on outer bottle again, when the bottle in the replacement, only need unscrew screw shell lid, screw shell lid receives the reaction force of interior bottle then can upwards move and break away from outer bottle this moment, and then can be light quick take out the interior bottle and change, interior bottle trades the bottle degree of difficulty little, and it is very convenient to use.

Detailed Description

The embodiment is given by fig. 1-5, the utility model comprises an outer bottle 1 and a bottle cap 2, wherein the bottle cap 2 is sleeved on the top of the outer bottle 1, an inner bottle 4 is arranged in the outer bottle 1, the inner bottle 4 extends to the top of the outer bottle 1, a screw socket cover 3 is sleeved on the top of the inner bottle 4, the screw socket cover 3 and the inner bottle 4 are connected through threads, the screw socket cover 3 is sleeved on the top of the outer bottle 1, the outer bottle 1 and the screw socket cover 3 are connected in an interference fit manner, the traditional installation mode is that the screw socket cover 3 directly presses the inner bottle 4 and then is clamped on the outer bottle 1, the screw socket cover 3 needs to be taken down when the inner bottle 4 is taken out, but the screw socket cover 3 is difficult to pull down when the inner bottle 4 is directly pulled out, and after the screw socket cover 3 and the inner bottle 4 are connected together through threads, the screw socket cover 3 can be jacked up through the reaction force of the inner bottle 4, so that the screw socket cover 3 and the outer bottle 1 are separated and replaced.

The inside piston 5 that is equipped with of interior bottle 4, there is collet 6 interior bottle 4 bottom through threaded connection, interior bottle 4 outer end processing has limit flange 7, limit flange 7 and the inside looks adaptation of outer bottle 1, limit flange 7's shape is similar quadrilateral through the chamfer processing, and is non-circular, and limit flange 7 and the inside looks adaptation of outer bottle again, therefore when rotating screw shell lid 3, interior bottle 4 can not rotate along with screw shell lid 3 in outer bottle 1 inside together, and limit flange 7 plays spacing effect.

Working principle:

when the bottle is normally used, the inner bottle 4 is positioned inside the outer bottle 1, the screw cap 3 is connected with the inner bottle 4 through threads, and is clamped at the top of the outer bottle 1 through interference fit, after the articles inside the inner bottle 4 are used up, the screw cap 3 can be unscrewed, at the moment, the screw cap 3 can be subjected to the reaction force of the screw teeth at the joint of the inner bottle 4 and the screw cap 3 to move upwards, and the inner bottle 4 and the screw cap 3 can be connected together through threads, after the screw cap 3 moves up to a certain height, the screw cap 3 and the outer bottle 1 are clamped, the screw cap 3 can be separated from the outer bottle 1, at the moment, when the screw cap 3 is extracted, the screw cap 3 and the inner bottle 4 are connected together, so that the inner bottle 4 can be taken out from the outer bottle 1 together along with the screw cap 3, the inner bottle 4 is replaced with the new inner bottle 4 filled with articles after the inner bottle 4 is taken out, and then the screw cap 3 is connected together through threads, and the screw cap 3 can be quickly assembled on the outer bottle 1 again after the screw cap 3 is inserted into the outer bottle 1.
