Description

Technical Field

[0001] The utility model relates to the technical field of daily chemical packaging, and relates to a replacement cream bottle. Background Art

[0002] A cream bottle is a container for holding paste or cream products and is widely used in cosmetics, skin care products, medicines and other fields. The earliest cream bottles had an inner liner fixed inside an outer bottle and were difficult to remove. After use, the entire cream bottle was discarded, causing a waste of resources and polluting the environment.

[0003] In response to this situation, some cream bottles with replaceable inner liners gradually appeared. For example, the Chinese utility model patent with application number 202321099696.9 (authorization announcement number CN220293216U) discloses a replaceable cream bottle with a threaded inner liners, which includes an outer bottle, a cavity is provided inside the outer bottle, a threaded inner liners matching with the top of the outer bottle is provided on the cavity, an inner cover matching with the top of the outer bottle is provided above the threaded inner liners, a hand-pull pad is provided on the top of the threaded inner liners, an outer cover matching with the outer side of the inner cover is provided on the top of the outer bottle, a stepped circular ring is provided on the top of the outer bottle, and a third threaded portion and a fourth threaded portion are provided on the stepped circular ring from top to bottom in sequence, the threaded inner liners include a U-shaped cylinder and an outer circular ring, the top of the outer circular ring is connected to the top of the U-shaped cylinder, and a second threaded portion matching with the third threaded portion is provided on the inner end of the outer circular ring away from the U-shaped cylinder, which has the advantages of convenient replacement, recycling, waste prevention, multiple protections and simplicity and practicality.

[0004] However, there are also shortcomings. Since the inner liner and the outer bottle are connected to each other by threads, it often takes many turns to separate the inner liner and the outer bottle. Moreover, during the replacement of the inner liner, it cannot be guaranteed that the inner liner used for replacement is tightened in the best position. If the inner liner is screwed too loose, although it will be convenient for replacement next time, it may become loose during use and affect the user experience. If it is screwed too tight, although the possibility of automatic loosening is reduced, it may cause the inner bottle to be unable to be screwed when disassembled next time, affecting the replacement of the inner liner.

[0005] Although there are some detachable connection between the inner liner and the outer bottle by means of snap-fitting in the market, due to the limitation of the snap-fitting structure itself, the snap-fitting part is usually exposed, thus affecting the overall appearance of the cream bottle.

[0006] Therefore, how to provide a cream bottle which can prevent the inner bottle from being over-tightened, ensure that the inner bottle will not loosen automatically during use, and prevent the connection between the inner liner and the outer bottle from being exposed is an urgent problem to be solved by technicians in this field.

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Figures 1 to 7 What is shown is a schematic diagram of this embodiment. The replacement cream bottle in this embodiment mainly includes an outer bottle 1, an inner liner 2 and a cover body 3.

[0027] refer to Figures 1 to 3 As shown, in this embodiment, the top of the outer bottle 1 has an opening 1a, the inner liner 2 can enter the outer bottle 1 from the opening 1a, and can also be moved out of the outer bottle 1 from the opening 1a, the cover body 3 can be detachably covered on the opening 1a of the outer bottle 1 and cover the inner liner 2 inside, the top edge of the inner liner 2 is also formed with a downwardly turned curling edge 2a, and a receiving space 2b for the bottle wall of the outer bottle 1 to extend into is formed between the curling edge 2a and the outer side wall of the inner liner 2, and a clamping block 2c is further provided on the side wall of the curling edge 2a facing the receiving space 2b, and a clamping groove 1b is provided on the outer side wall of the outer bottle 1 for the clamping block 2c to be clamped from top to bottom so that the outer bottle 1 and the inner liner 2 are locked with each other, and when the inner liner 2 and the outer bottle 1 are in a mutually locked state, the curling edge 2a on the inner liner 2 can cover the clamping groove 1b.

[0028] In order to optimize the slot structure between the inner liner 2 and the outer bottle 1 so that the inner liner 2 and the outer bottle 1 can be better locked or unlocked with each other, refer to Figure 2 and Figure 3As shown, in this embodiment, a connecting wall 1c that can extend into the accommodating space 2b is formed on the outer side wall of the outer bottle 1, and a card slot 1b is provided on the connecting wall 1c. The card slot 1b includes a locking area 1b1 and a guide area 1b2. The locking area 1b1 is formed on the connecting wall 1c along the circumferential direction, and the guide area 1b2 extends downward from the top edge of the connecting wall 1c and is connected to the locking area 1b1. When the inner liner 2 enters the outer bottle 1 from top to bottom, the card block 2c can be matched in the guide area 1b2, and can enter the locking area 1b1 under the guiding action of the guide area 1b2 during the relative rotation of the inner liner 2 and the outer bottle 1, so that the inner liner 2 is locked on the outer bottle 1.

[0029] Secondly, in order to make the card block 2c enter the locking area 1b1 more conveniently and accurately, refer to Figure 2 As shown, the guide area 1b2 in this embodiment is gradually inclined from the top edge of the connecting wall 1c toward the obliquely downward direction of the rotation direction when the inner liner 2 is locked and connected to the locking area 1b1. The channel width of the guide area 1b2 for the block 2c to move is greater than the width of the block 2c.

[0030] In addition, in order to prevent the inner liner 2 in the locked state from being easily loosened and affecting daily use, refer to Figure 2 and Figure 6 As shown, in this embodiment, a limit block 1b3 which can be adapted to the clamping block 2c to limit the inner liner 2 from rotating freely without external force is specially provided in the locking area 1b1, and the cross section of the limit block 1b3 is in an outer arc shape.

[0031] At the same time, in order to make the locking and unlocking process of the inner liner 2 more stable and smooth, refer to Figure 6 As shown, in this embodiment, there are at least two blocks 2c and slots 1b, and the blocks 2c are spaced apart along the circumference of the inner liner 2. Here, the bottom of each block 2c is flush with or higher than the bottom of the curl 2a, thereby better preventing the block 2c from being exposed at the bottom of the curl 2a.

[0032] In addition, in order to enable the user to more conveniently rotate the inner liner 2 to lock or unlock it when replacing the inner liner 2, refer to Figure 2 and Figure 3 As shown, in the present embodiment, an anti-skid groove 2a1 is formed on the outer wall of the curled edge 2a for increasing friction when the inner liner 2 is rotated. There are at least two anti-skid grooves 2a1, and each anti-skid groove 2a1 is spaced apart along the circumference of the inner liner 2. The anti-skid grooves 2a1 shown in the figure are provided with two, and of course we can also set more according to the requirements.

[0033] In this embodiment, in order to optimize the detachable structure between the outer bottle 1 and the cover body 3, Figures 2 to 4As shown, an external thread 1d is formed on the outer wall of the outer bottle 1, and an internal thread 3a that can adapt to the external thread 1d is formed on the cover body 3. The outer bottle 1 and the cover body 3 can be detachably locked together through the threaded connection of the external thread 1d and the internal thread 3a. The external thread 1d is located below the connecting wall 1c.

[0034] In this embodiment, in order to prevent the cover body 3 from being over-tightened or over-loosened, and to prevent the cover body 3 from automatically loosening without external force, Figure 2 and Figure 5 As shown, a positioning block 1e is also formed on the outer bottle 1, and a positioning groove 3b that can adapt to the positioning block 1e is provided on the cover body 3. When the outer bottle 1 and the cover body 3 are in a mutually locked state, the positioning block 1e can be embedded in the positioning groove 3b to limit the cover body 3 from being over-tightened or automatically loosened without external force.

[0035] In addition, in order to optimize the structure of the positioning groove 3b, the locking or unlocking between the cover body 3 and the outer bottle 1 can be more controllable and easy to operate. Figure 5 As shown, in this embodiment, the cover body 3 is also specially provided with a first convex portion 3b1 and a second convex portion 3b2 which are spaced apart from each other in sequence along the tightening direction of the cover body 3. Figure 4 The direction indicated by the middle arrow A is the tightening direction of the cover body 3. The interval between the first protrusion 3b1 and the second protrusion 3b2 forms a positioning groove 3b. The positioning block 1e is formed with an inclined surface 1e1 at the front end in the tightening direction of the cover body 3, and a first step surface 1e2 is formed at the rear end in the tightening direction of the cover body 3. The cross-section of the first protrusion 3b1 is arc-shaped, and the second protrusion 3b2 is also formed with a second step surface 3b3 adapted to the first step surface 1e2 at the front end in the tightening direction of the cover body 3. When the cover body 3 is tightened to the set position, the second step surface 3b3 can resist the first step surface 1e2 to limit the cover body 3 from being excessively tightened.

[0036] It is necessary to explain here that in the present embodiment, a downwardly turned curling edge 2a is formed on the edge of the inner liner 2, and a receiving space 2b for the bottle wall of the outer bottle 1 to extend into is formed between the curling edge 2a and the outer side wall of the inner liner 2, and a clamping block 2c is provided on the side wall of the curling edge 2a facing the receiving space 2b, and a clamping groove 1b is provided on the outer side wall of the outer bottle 1 for the clamping block 2c to be clamped in from top to bottom so that the outer bottle 1 and the inner liner 2 can be locked with each other. When the inner liner 2 and the outer bottle 1 are locked with each other, the curling edge 2a on the inner liner 2 can just cover the clamping groove 1b, so that the clamping groove 1b and the clamping block 2c are both built into the receiving space 2b which is not easily visible, thereby avoiding that the locking parts of the inner liner 2 and the outer bottle 1 are exposed to the outside and affect the appearance of the bottle. At the same time, if Figure 7As shown, locking marks 2a2 and unlocking marks 2a3 are arranged at intervals along the circumferential direction on the outer circumference of the curling edge 2a, so that the user can more conveniently and intuitively unlock or lock the inner liner 2. In addition, since the cream bottle adopts a slot structure that can be quickly locked or unlocked, it can also effectively avoid the disadvantages caused by the inner liner 2 being screwed too tight or too loose during the replacement process, thereby making the replacement process of the inner liner 2 easier and more convenient.
