[0002] Cosmetics, skin care products, etc. are usually packaged in packaging containers to facilitate users to use and carry. The packaging container includes a cover body, wherein the inner wall of the cover body is connected with the valve seat of the valve by interference fit. When the contents in the packaging container need to be applied or used, the cover body needs to be manually disassembled (such as unscrewed or pulled out), in the process, the cover body drives the valve seat to act, thereby opening the passage on the valve, and then the contents can flow out from the passage on the valve by squeezing the packaging container or the like.

[0003] The cover body, the valve and the valve seat are all manufactured by injection molding. Due to the manufacturing precision, the size of each component is difficult to accurately control. When the size of any component deviates, it will affect the overall assembly effect, and the reliability and stability of the overall structure will be poor. For example, if the cover body and the valve seat are too loose, the valve seat will not act with the cover body when the cover body is disassembled, resulting in that the valve cannot be normally opened. For another example, if the cover body, the valve and the valve seat are too tight, the valve will act with the cover body and the valve seat when the cover body is disassembled, causing the valve to separate from the main body of the packaging container. If fine processing is used, the production cost of the packaging container will be greatly increased.

[0045] Embodiment one

[0046] Reference Figures 1-3 In this embodiment, a packaging container is proposed, which comprises a main body 100, a movable assembly 200, a cover 300 and an elastic member 400. In the drawings, only a part of the main body 100 is shown for easy observation.

[0047] The main body 100 comprises a discharge hole 101 and a mounting cavity 110, and the storage cavity 102 of the main body 100, the discharge hole 101 and the mounting cavity 110 are sequentially communicated, wherein the movable assembly 200 is movably arranged in the mounting cavity 110.

[0048] The cover 300 is detachably connected with the main body 100. The cover 300 is used to drive the movable assembly 200 to block the discharge hole 101 when it is mounted on the main body 100, so that the discharge hole 101 is in a closed state. Since the discharge hole 101 is closed, the material in the storage cavity 102 of the main body 100 will not leak.

[0049] The elastic member 400 is arranged in the mounting cavity 110. The elastic member 400 is used to drive the movable assembly 200 to separate from the discharge hole 101 when the cover 300 is detached from the main body 100, so that the discharge hole 101 is in an open state. After the discharge hole 101 is opened, the user can squeeze the main body 100 or the like to realize that the material in the storage cavity 102 can be discharged from the discharge hole 101 for the user to use. Figure 3 The dashed line indicates the flow direction of the material when it is discharged.

[0050] As Figure 4As shown, the mounting cavity 110 comprises a first chamber 111 and a second chamber 112 which are in communication, and the storage cavity 102, the discharging hole 101, the first chamber 111 and the second chamber 112 are in communication in sequence, wherein the discharging hole 101 is arranged at the bottom of the first chamber 111.

[0051] The top end of the first chamber 111 is connected with the bottom end of the second chamber 112, and the cross-sectional area of the top end of the first chamber 111 is smaller than that of the bottom end of the second chamber 112. The tail end of the elastic member 400 abuts against the bottom surface of the second chamber 112. Referring to Figure 4 , the bottom surface of the second chamber 112 is the top surface of the first chamber 111, that is, the part indicated by the arrow a in the figure.

[0052] In the embodiment, the elastic member 400 is a spring, wherein the outer diameter of the spring is larger than the inner diameter of the top end of the first chamber 111. In this way, the elastic member 400 cannot enter the first chamber 111.

[0053] As shown in the figure, Figure 5 The movable assembly 200 comprises a sleeve 210.

[0054] The sleeve 210 comprises a plugging section 211 for plugging the discharging hole 101, and the plugging section 211 is slidably inserted into the mounting cavity 110. The elastic member 400 is sleeved on the plugging section 211.

[0055] Further, an annular part 212 is arranged on the outer wall of the sleeve 210, and a connecting cavity 213 is formed between the outer wall of the plugging section 211 and the annular part 212. One end of the annular part 212 is spaced apart from the plugging section and forms an inlet part 214. The cross sections of the connecting cavity 213 and the inlet part 214 are annular structures.

[0056] As shown in the figure, Figure 4 The main body 100 comprises a plug-in part 120 which is arranged around the second chamber 112 of the mounting cavity 110. The plug-in part 120 is slidably inserted into the connecting cavity 213 through the inlet part 214.

[0057] During assembly, the elastic member 400 is first sleeved on the plugging section 211 of the sleeve 210, and then the plugging section 211 is inserted into the second chamber 112. The top end of the elastic member 400 is located in the connecting cavity 213, and the top end of the elastic member 400 abuts against the end surface of the connecting cavity 213, wherein the elastic member 400 is located between the plugging section 211 and the plug-in part 120.

[0058] As shown in the figure, Figure 4 and Figure 5As shown, the inner wall of the annular portion 212 is provided with a first matching portion 2121, and the outer wall of the insertion portion 120 is provided with a second matching portion 121, and the first matching portion 2121 corresponds to the second matching portion 121. The first matching portion 2121 is used to cooperate with the second matching portion 121 to constrain the insertion portion 120 in the connecting cavity 213.

[0059] The first matching portion 2121 and the second matching portion 121 can both adopt a ring-shaped protruding structure, the inner diameter of the first matching portion 2121 is smaller than the outer diameter of the second matching portion 121, and the inner diameter of the connecting cavity 213 is greater than or equal to the outer diameter of the second matching portion 121. When assembling, the insertion portion 120 is aligned with the inlet portion 214, and the main body 100 and the sleeve 210 are extruded, so that the first matching portion 2121 or / and the second matching portion 121 is deformed, and then the second matching portion 121 enters the connecting cavity 213. Because the inner diameter of the first matching portion 2121 is smaller than the outer diameter of the second matching portion 121, under the action of insufficient external force, the second matching portion 121 is always located in the connecting cavity 213 due to the limitation of the first matching portion 2121, which not only realizes the slidable connection between the main body 100 and the sleeve 210, but also makes the main body 100 and the sleeve 210 not separate under the action of the elastic member 400.

[0060] As shown in the figure, Figure 6 The inside of the cover 300 is provided with an acting portion 310 corresponding to the annular portion 212. The acting portion 310 is used to drive the bottom of the plugging section 211 to block the discharge hole 101 when the cover 300 is installed on the main body 100, so that the discharge hole 101 is in a closed state. The acting portion 310 is in a ring structure, and the inner diameter of the acting portion 310 is smaller than the outer diameter of the annular portion 212.

[0061] As shown in the figure, Figure 7 In this embodiment, the movable assembly 200 further includes an application member 220, which includes an assembly portion 221 and a head portion 222. The assembly portion 221 is inserted into the inside of the sleeve 210, and the head portion 222 is located outside the sleeve 210.

[0062] The assembly portion 221 and the sleeve 210 can be fixedly connected by interference fit, threaded connection, etc.

[0063] The application member 220 can be made of metal, plastic, sponge, fur, etc.

[0064] When the application member 220 is made of metal or plastic, a flow cavity can be formed in the inside of the application member 220, so that the material discharged from the discharge hole 101 can be discharged through the flow cavity, thereby allowing the user to apply, etc.

[0065] When the coating member 220 is made of sponge or fluff, etc., since the sponge or fluff has pores, the material can be discharged through the pores of the sponge or fluff, so that the user can perform coating, etc.

[0066] As shown in Figure 4 , the bottom surface of the installation cavity 110 is provided with a convex column 113, which is used for guiding the material discharged from the discharge hole 101. Among them, the discharge hole 101 is multiple and is arranged along the circumference of the convex column 113. The convex column 113 can be located in the first installation cavity 110 as a whole.

[0067] In this embodiment, the outer wall of the main body 100 is provided with a first assembly structure 130, and the inner wall of the cover 300 is provided with a second assembly structure 320.
