Description

Technical Field

[0001] The utility model relates to a cosmetic bottle, in particular to a replacement cream bottle. Background Art

[0002] A cream bottle is a cosmetic bottle for containing paste-type cosmetics. The structure of the cream bottle in the prior art generally includes a bottle body, an inner liner is inserted into the bottle body, the paste-type cosmetics are placed in the inner liner, a cover sheet is covered on the top of the inner liner, and a bottle cap is screwed on the upper end of the bottle body by a threaded connection, and the bottle cap covers the inner liner. The inner liner of the cream bottle is usually replaceable, and a groove with an opening facing upward is provided on the bottle body, and the inner liner is inserted into the groove. Some cream bottles have empty grooves at both ends of the top of the bottle body, and ear buckles are protruding on the inner liner, and the ear buckles are inserted into the protruding ears, such as a thick-walled replacement cream bottle disclosed in CN 220800373 U. However, this installation method of the inner liner is defective, because the inner liner only prevents the inner liner from falling off by the friction between its outer wall and the inner wall of the bottle body. In order to prevent the inner liner from falling off as much as possible, the inner liner and the bottle body must be clamped very tightly, which makes it very difficult to remove the inner liner. However, if the inner liner and the bottle body are not clamped tightly, the inner liner is easy to fall off. Utility Model Content

[0003] In view of the above-mentioned defects of the prior art, the purpose of the present utility model is to provide a replacement cream bottle.

[0004] The technical solution of the utility model is: a replaceable cream bottle, comprising a bottle body, an inner liner and a bottle cap, the bottle body having a groove with an opening facing upward and for the inner liner to be placed in, the outer side of the inner liner having an annular sleeve, the sleeve having a mounting groove with an opening facing downward, a circular connecting portion convexly provided at the upper end of the bottle body, the lower end of the sleeve is sleeved outside the upper end of the connecting portion, a shoulder sleeve is detachably and rotatably sleeved outside the connecting portion, the shoulder sleeve presses down the lower end of the sleeve, and the bottle cap is connected to the upper end of the sleeve by a threaded connection.

[0005] Furthermore, an annular arc groove is provided on the inner wall of the lower end of the installation groove, and an annular arc convex strip is convexly provided on the outer wall of the upper end of the connecting part, and the arc convex strip is inserted into the arc groove.

[0006] Furthermore, the shoulder sleeve has an axially arranged sleeve hole, which passes through from top to bottom. A plurality of clamping blocks are evenly distributed circumferentially on the inner wall of the lower end of the sleeve hole, and a plurality of locking blocks are evenly distributed circumferentially on the outer wall of the lower end of the connecting part. The locking block has a clamping groove for the clamping block to be inserted into.

[0007] Furthermore, the locking block is in an inverted L-shape, and one end of the locking block is provided with a stopper for blocking the clamping block.

[0008] Furthermore, a ring-shaped pressing ring is provided on the upper end hole wall of the sleeve hole, and a ring-shaped convex ring is convexly provided on the lower end outer wall of the sleeve head, and the pressing ring is pressed on the top of the convex ring.

[0009] The application of the replacement cream bottle provided by the utility model has the beneficial effect that the shoulder sleeve presses down the lower end of the sleeve head, that is, the shoulder sleeve can press the inner liner, and the inner liner is pressed in the vertical direction, so the inner liner will not fall off, so the inner liner does not need to be stuck very tightly to the bottle body, the inner liner only needs to be inserted into the bottle body, and when the inner liner needs to be replaced, the shoulder sleeve is unscrewed first, and the inner liner can be easily removed for replacement.

DETAILED DESCRIPTION

[0016] In order to more intuitively and completely understand the technical solution of the utility model, the following non-limiting feature description is now provided in conjunction with the accompanying drawings of the utility model:

[0017] like Figure 1 — Figure 5 As shown, the replacement cream bottle includes a bottle body 1, an inner liner 2 and a bottle cap 3. The bottle body 1 has a groove 11 with an opening facing upward and for the inner liner 2 to be placed in. The outer side of the inner liner 2 has an annular sleeve 21, and the sleeve 21 has a mounting groove 211 with an opening facing downward. A circular connecting portion 12 is convexly provided at the upper end of the bottle body 1. The lower end of the sleeve 21 is sleeved on the outside of the upper end of the connecting portion 12. A shoulder sleeve 4 is detachably and rotatably sleeved on the outside of the connecting portion 12. The shoulder sleeve 4 presses down the lower end of the sleeve 21, and the bottle cap 3 is connected to the upper end of the sleeve 21 by a threaded connection.

[0018] like Figure 3 , Figure 4As shown, the lower inner wall of the mounting groove 211 has an annular arc groove 2111 , and the upper outer wall of the connecting portion 12 has an annular arc convex strip 121 convexly disposed thereon. The arc convex strip 121 is inserted into the arc groove 2111 to play a positioning role.

[0019] like Figure 2 , Figure 3 and Figure 5 As shown, the shoulder sleeve 4 has an axially arranged sleeve hole 41, which is through from top to bottom, and a plurality of clamping blocks 411 are evenly distributed on the inner wall of the lower end of the sleeve hole 41 in a circumferential manner, and a plurality of locking blocks 122 are evenly distributed on the outer wall of the lower end of the connecting portion 12 in a circumferential manner, and the locking blocks 122 have a clamping groove 1221 for the clamping blocks 411 to be clamped into. When installing the shoulder sleeve 4, the shoulder sleeve 4 is firstly sleeved outside the connecting portion 12, and then the shoulder sleeve 4 is rotated so that the clamping blocks 411 are clamped into the clamping groove 1221, and the shoulder sleeve 4 is fixed.

[0020] like Figure 2 As shown, the locking block 122 is in an inverted L-shape, and one end of the locking block 122 has a stopper 1222 for blocking the clamping block 411 .

[0021] like Figure 2 — Figure 5 As shown, in order to press down the inner liner 2 and prevent the inner liner 2 from falling off, an annular pressing ring 412 is provided on the upper end hole wall of the sleeve hole 41, and an annular convex ring 22 is convexly provided on the lower end outer wall of the sleeve head 21, and the pressing ring 412 is pressed on the top of the convex ring 22.

[0022] The replacement cream bottle provided by the utility model has a shoulder sleeve 4 that presses down the lower end of the sleeve head 21, that is, the shoulder sleeve 4 can press down the inner liner 2. The inner liner 2 is pressed in the vertical direction and the inner liner 2 will not fall off. Therefore, the inner liner 2 does not need to be tightly clamped to the bottle body 1. The inner liner 2 only needs to be inserted into the bottle body 1. When the inner liner 2 needs to be replaced, the shoulder sleeve 4 is first unscrewed, and the inner liner 2 can be easily removed for replacement.

[0023] Of course, the above are only preferred embodiments of the present invention, and the patent scope of the present invention is not limited thereto. All simple modifications and equivalent structural changes made using the description and drawings of the present invention should be included in the patent protection scope of the present invention.
