The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] In this application, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0031] In this application, the terms "comprises" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a system, product or device comprising a series of units is not necessarily limited to those units explicitly listed, but may include other units not explicitly listed or inherent to these products or devices.

[0032] See also Figure 1 to Figure 7 , an embodiment of the present application provides a packaging bottle that is easy to assemble, including a bottle body 100 and a vacuum pump 200 disposed in the bottle body 100. .

[0033] The bottle 100 is used to hold liquid cream cosmetics. When it is needed, the cosmetics can be pumped out by pressing the vacuum pump 200. The vacuum pump 200 can adopt the existing technology and will not be described in detail in this embodiment. For ease of understanding, the packaging bottle of this application has a relative top and bottom. For details, please refer to Figure 1 In the example, X is the top and Y is the bottom.

[0034] Taking into account the problem of reducing pollution, the packaging bottle involved in this application also includes a cover body, the shape of the cover body can be set according to needs, and no specific elaboration is made without the application.

[0035] Existing packaging bottles have various shapes, many components, and the overall assembly is relatively complicated. In order to solve this problem, the bottle body 100 of the present application includes an inner bottle 130, an outer bottle 110, a pump seat 300 for fixing the vacuum pump 200, and a shoulder sleeve 120 surrounding the pump seat 300 and connected to the outer bottle 110, wherein the inner bottle 130 is threadedly connected to the pump seat 300 (of course, in order to increase the sealing, a sealing ring 321 can also be provided between the inner bottle 130 and the pump seat 300), and an axial limiting structure and a circumferential limiting structure are provided between the shoulder sleeve 120 and the pump seat 300.

[0036] See also Figure 1 to Figure 6 , the inner circumferential surface of the shoulder sleeve 120 is provided with a first slot 121 extending in the circumferential direction, the edge of the pump seat 300 extends into the first slot 121, and the first slot 121 cooperates with the edge of the pump seat 300 to achieve axial positioning of the two. Specifically, in this embodiment, the inner wall of the shoulder sleeve 120 has a circumferentially arranged limiting rib 126, and the limiting rib 126 and the top of the shoulder sleeve 120 form the first slot 121. When the shoulder sleeve 120 cooperates with the pump seat 300, it is only necessary to pass the edge of the pump seat 300 over the limiting rib 126 to achieve axial positioning with the shoulder sleeve 120. Of course, in order to facilitate the cooperation between the two, the bottom of the limiting rib 126 has a guiding inclined surface 127. Preferably, there are multiple limiting ribs 126 and they are evenly arranged in the circumferential direction. In one embodiment, the outer bottle 110 is located below the first slot 121 to further limit the pump seat 300 from being separated from the shoulder sleeve 120. Specifically, under this structure, even if the limiting rib 126 fails (ie, the edge of the pump seat 300 is out of the first slot 121 ), the pump seat 300 can be against the top of the outer bottle 110 to avoid being directly out of the shoulder sleeve 120 .

[0037] Furthermore, in order to achieve the circumferential limit of the shoulder sleeve 120 and the pump seat 300, the inner circumferential surface of the shoulder sleeve 120 and the edge of the pump seat 300 are respectively provided with a first latching tooth 122 and a second latching tooth 310 that cooperate to limit the relative rotation of the two. Considering the stability of the structure, the number of the first latching teeth 122 and the second latching teeth 310 is multiple and evenly arranged along the circumference. In this embodiment, the second latching teeth 310 are distributed all over the edge of the pump seat 300 (i.e., forming the shape of a gear ring), and the first latching teeth 122 are divided into 4 large groups, and 7 first latching teeth 122 are arranged between each group (see Figure 6 ), and each group is evenly arranged in the circumferential direction.

[0038] See also Figure 4 and Figure 7, one of the shoulder sleeve 120 and the outer bottle 110 is provided with a block 111, and the other is provided with a second slot 123 arranged along the circumference and cooperating with the block 111 and a notch 124 allowing the block 111 to enter the second slot 123, and the two cooperate to achieve axial positioning. Preferably, in this embodiment, the second slot 123 is provided on the inner wall of the shoulder sleeve 120, and the block 111 is provided on the outer periphery of the outer bottle 110. After the two cooperate, the block 111 of the outer bottle 110 is hidden in the shoulder sleeve 120, so that the overall appearance is more beautiful. In this embodiment, the number of the second slot 123 and the block 111 is multiple, and they are evenly distributed along the circumference.

[0039] In order to achieve circumferential limitation of the two, a positioning mechanism for limiting the relative rotation of the shoulder sleeve 120 and the outer bottle 110 is provided between the second slot 123 and the block 111. Specifically, the positioning mechanism includes a protrusion 125 provided in the second slot 123 and a positioning groove 112 provided on the block 111.

[0040] When the shoulder sleeve 120 is assembled with the outer bottle 110, it is only necessary to insert the block 111 on the outer bottle 110 into the notch 124 of the shoulder sleeve 120, and then rotate the block 111 along the direction of the second slot 123 until the protrusion 125 is engaged with the positioning groove 112, and the assembly of the two is completed.

[0041] See also Figure 1 to Figure 3 In order to facilitate the installation of the vacuum pump 200, a hole column 311 for installing the vacuum pump 200 is provided at the center of the pump seat 300. In one embodiment, the packaging bottle of the present application also includes a push cap 400 that is movably matched with the pump seat 300 (that is, the push cap 400 can move axially relative to the pump seat 300. In order to reset the push cap 400, a reset spring is also provided in the packaging bottle of the present application, which is not shown in the figure). Furthermore, the push cap 400 and the shoulder sleeve 120 cooperate to shield the pump seat 300, making the overall appearance more beautiful. In order to smoothly pump out the cosmetics, the push cap 400 has a liquid outlet 410 aligned with the vacuum pump 200. Of course, considering the problem of buffering the discharge and sealing the liquid outlet 410, a sealing sheet 412 is also provided in the liquid outlet 410.

[0042] In one embodiment, there is an anti-drop structure between the shoulder cover 120 and the pressing cap 400. Figure 1 and Figure 3 The top of the shoulder sleeve 120 has an inner flange 128, and the bottom of the pressing cap 400 has an outer flange 413. The outer diameter of the outer flange 413 is larger than the inner diameter of the inner flange 128. When the pressing cap 400 is reset under the action of the reset spring, the anti-detachment structure is used to limit the pressing cap 400 from detaching from the shoulder sleeve 120.

[0043] Furthermore, the pressing cap 400 has a liquid conducting channel 411 (the top of the liquid conducting channel 411 is the liquid outlet 410) connected to the vacuum pump 200. The vacuum pump 200 includes a piston 210 and a pump body 220. The piston 210 is sleeved on the outer periphery of the liquid conducting channel 411 and is linked to the pressing cap 400. When it is needed, the pressing cap 400 is pressed down, and the cosmetics in the bottle body 100 are pumped out from the liquid outlet 410 through the liquid conducting channel 411.

[0044] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0045] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
