Description

Technical Field

[0001] This application relates to the field of cosmetic packaging technology, and more particularly to an application device and a skin care product container. Background Technology

[0002] As people's living standards improve, their demand for skincare products is increasing, along with the growing requirements for the functionality and personalization of product bottles. For example, eye cream bottles used to have only a simple squeezing function; the cream was simply squeezed onto the hand and applied to the skin around the eyes. With packaging upgrades and improvements, some eye cream bottles have begun to feature applicator heads with dispensing nozzles. These nozzles dispense the eye cream directly from the nozzle and are then applied around the eyes. However, existing eye cream bottles with applicator heads are inconvenient to press down on the cap because the applicator is located on the cap. Generally, the cream is dispensed through a soft tube; that is, the applicator head is rotated to squeeze out the internal tube, rather than being dispensed by pressing down on the cap. Utility Model Content

[0003] The purpose of this application is to provide an application device and a skin care product container to solve the problem that the cap of an eye cream bottle with an application head is inconvenient to press in the prior art.

[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0055] In the description of this application, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the meaning of the above terms in this application according to the specific circumstances.

[0056] In the description of this embodiment, the terms "upper," "lower," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used only for distinction in description and have no special meaning.

[0057] This application provides an applicator. For example... Figures 1 to 4 As shown, in this embodiment, the application device 10 includes a mounting base 280, a movable component 100, and a pump assembly 200. For example... Figure 2 As shown, the movable member 100 is movably mounted on the mounting base 280, and the movable member 100 can slide axially relative to the mounting base 280 on the mounting base 280. Figure 2 As shown in the embodiments of this application, the axial direction refers to the Z direction shown in the attached figures, and the radial direction is any direction perpendicular to the Z direction, such as the X and Y directions shown in the attached figures. Figure 2 As shown, the movable member 100 is provided with an applicator head 110 and a pressing surface 120, which are arranged radially along the movable member 100. A pressing space A is formed between the applicator head 110 and the pressing surface 120 for inserting a finger. Figure 4As shown, the applicator head 110 has a first liquid outlet channel 111. A pump assembly 200 is mounted on the applicator. The pump assembly 200 can be any type of pump that dispenses liquid by pressing. The pump assembly 200 includes a piston rod 220 for pumping, which is connected to a movable member 100. Pressing the movable member 100 drives the piston rod 220 to reciprocate axially. The piston rod 220 has a second liquid outlet channel 221, which connects the container to the first liquid outlet channel 111, allowing liquid pumped from the container to flow out of the applicator head 110. The container can be any type of skincare product container, such as an eye cream bottle or a serum bottle.

[0058] like Figures 9 to 11 As shown, the application device 10 also includes a top cover 400 and a physiotherapy device 300. The top cover 400 is detachably disposed on the movable member 100 and has a recess 401 recessed into the pressing space A. The physiotherapy device 300 is detachably disposed on the top cover 400 and is at least partially housed in the recess 401.

[0059] Combination Figure 4 and Figure 14 After the applicator 10 is installed on the bottle, when the movable part 100 is pressed, the movable part 100 moves axially downward on the mounting base 280, driving the piston rod 220 of the press pump assembly 200 to move downward, pumping out liquid. The liquid flows from the second liquid outlet channel 221 in the piston rod 220 to the first liquid outlet channel 111 in the applicator head 110 and then flows out from the applicator head 110.

[0060] In the application of this application, the applicator 10, such as Figure 2 As shown, an applicator head 110 and a pressing surface 120 are arranged radially along the movable member 100. A pressing space A is formed between the applicator head 110 and the pressing surface 120 for inserting a finger, thus facilitating the user to insert their finger into the pressing space A and press the pressing surface 120 to squeeze out the skincare product liquid, making pressing convenient. In conventional technology, the applicator head 110 occupies the entire top space of the movable member 100, making pressing inconvenient.

[0061] Simultaneously, the pressing space A on the movable part 100 forms a recess 401 on the upper cover 400, which accommodates the physiotherapy device 300. Figure 9 As shown, when the physiotherapy device 300 is not in use, it can be placed in the recess 401 of the upper cover 400. Because it is housed in the recess 401, the physiotherapy device 300 does not require much additional space for placement. (Reference) Figure 10When using the physiotherapy device 300, simply remove it from the top cover 400. The above-mentioned application device innovatively utilizes the pressing space A on the movable part 100 to externally attach a physiotherapy device 300.

[0062] In one embodiment, such as Figure 3 and Figure 4 As shown, the applicator head 110 includes a fixing post 115 and an applicator part 116. The fixing post 130 is connected to the movable part 100, and the fixing post 130 extends along the axial direction of the mounting base 280 in a direction away from the pressing surface 120, that is, as shown in the figure. Figure 2 As shown, it extends upwards. The application portion 116 is disposed on the fixing post 115, and the application portion 116 is inclined relative to the fixing post 130. The application portion 116 extends radially along the fixing post 130, that is, as shown... Figure 2 As shown, the applicator 116 extends obliquely to the right and upward, and its projection on the pressing surface 120 in the axial direction of the fixing post 130 at least partially overlaps with the applicator head 116. The applicator surface 114 of the applicator head 116 is located on the side of the applicator head 116 opposite to the pressing space A. In the embodiments of this application, as... Figure 2 As shown, the application surface 114 faces the side of the application head 110 away from the pressing space A. This ensures that the application surface 114 and the pressing space A are on different sides, preventing interference between the application and pressing operations and facilitating both. Simultaneously, the design of the application portion 116, which is inclined and extends radially along the fixing post 130, and whose projections of the application portion 116 and the pressing surface 120 in the axial direction of the fixing post 130 at least partially overlap, causes the application portion 116 to protrude obliquely towards the pressing space A. Figure 2 As shown, the portion H of the application part 116 located to the right of the vertical dotted line protrudes into the pressing space A, thus increasing the area of ​​the application surface 114. Simultaneously, the application surface 114 protrudes obliquely into the pressing space A, ensuring it does not obstruct finger insertion into the pressing space A and does not hinder the pressing operation. Furthermore, the application part 116 is fixed to the fixing post 130 and maintains a certain axial distance from the pressing surface 120, thus not affecting the pressing operation from the pressing surface 120 and providing sufficient pressing space A.

[0063] refer to Figure 2 The projections of the applicator 116 and the pressing surface 120 onto the axial direction of the fixing post 130 at least partially overlap, including both cases of complete projection overlap and partial projection overlap. Specifically, Figure 2 Since the applicator 116 extends only slightly into the pressing space A, its projection on the pressing surface 120 only partially overlaps with the projection on the fixing post 130 in the axial direction. In other alternative embodiments, if the applicator 116 extends further into the pressing space A, completely covering the space above the pressing surface 120, then the applicator 116 will completely overlap with the projection of the pressing surface 120 on the axial direction of the fixing post 130.

[0064] Specifically, such as Figure 3 As shown, the fixed post 115 and the movable part 100 are integrally molded and made of plastic. The application part 116, since it comes into contact with the skin, is made of a softer material such as silicone or rubber. Figure 4 As shown, an insertion hole can be provided at the bottom of the coating part 116 so that the coating part 116 can be directly inserted into the fixing post 115, which makes the installation of the coating part 116 more convenient.

[0065] In one embodiment, such as Figure 1 As shown, the pressing surface 120 extends from the base 112 of the applicator head 110 to the edge of the movable part 100, making the pressing surface 120 larger and the contact area between the finger and the pressing surface 120 larger, thus making it more stable when pressing and less prone to slippage. This also allows for more precise control of the pressing pressure, thereby more accurately controlling the amount of liquid dispensed.

[0066] In addition, such as Figure 1 As shown, anti-slip textures can also be provided on the pressing surface 120 to increase the friction of the pressing surface 120 and prevent slippage.

[0067] Furthermore, such as Figure 2 As shown, the applicator head 110 and the pressing surface 120 can also be connected by an arc surface 113. Specifically, the arc surface 113 is connected to the root 112 of the applicator head 110. Based on the pressing surface 120 extending outward from the root 112 of the applicator head 110, an arc surface 113 is simultaneously provided between the root 112 of the applicator head 110 and the pressing surface 120, as shown... Figure 2 As shown, this allows the fingertips to contact the curved transition surface, which then provides restraint and support. Simultaneously, the fingertips fitting snugly against the curved transition surface makes pressing easier and provides a better feel.

[0068] like Figure 2 As shown, in one embodiment, the included angle α between the pressing surface 120 and the radial plane of the movable member 100 is greater than or equal to 0 and less than or equal to 15°. Setting the included angle α to greater than or equal to 0 and less than or equal to 15° results in a smaller inclination of the pressing surface 120, avoiding excessive tilting that could cause finger slippage. In a specific embodiment of this application, α is 10°.

[0069] In one embodiment, such as Figure 5 As shown, the applicator head 110 is equipped with a light-emitting plate 140. (As indicated...) Figure 5The light-emitting plate 140 is positioned adjacent to the application surface 114 of the application head 110, with the light-emitting surface of the light-emitting plate 140 facing the application surface 114. This allows light emitted from the light-emitting element 141 on the light-emitting plate 140 to be emitted through the application surface 114, irradiating the skin for phototherapy. It is understood that the application surface 114 is made of a light-transmitting material to facilitate light transmission. The light-emitting element 141 on the light-emitting plate 140 can be an LED. The light emitted by the light-emitting element 141 can be red, blue, green, or yellow; a single type of light or a combination of multiple light sources can be used.

[0070] It is understandable that, such as Figure 5 As shown, the light-emitting plate 140 is positioned away from the first liquid outlet channel 111 in the applicator head 110, thereby avoiding interference with the liquid outlet of the first liquid outlet channel 111.

[0071] In other alternative embodiments, the light-emitting plate 140 may not be provided in the applicator head 110, such as... Figure 11 As shown, instead of a light therapy lamp panel 310, a light therapy lamp panel 310 is provided in the physiotherapy device 300. The light therapy lamp panel 310 is positioned adjacent to the physiotherapy surface 301 of the physiotherapy device 300, so that the light therapy lamp panel 310 emits light towards the surface of the physiotherapy device 300. The physiotherapy device 300 also includes a battery 320. A button 330 and a charging post 340 are provided on the side wall of the physiotherapy device 300. The charging post 340 is electrically connected to the battery 320, thereby charging the battery 320 through the charging post 340.

[0072] like Figure 10 As shown, the physiotherapy device 300 may include a physiotherapy head 302 and a handle 303 connected to each other. The physiotherapy head 302 can stimulate the skin to provide physiotherapy. The physiotherapy head 302 can provide physiotherapy by setting the aforementioned phototherapy lamp plate 310, or by setting electrodes or vibrating massage elements to provide physiotherapy to the skin.

[0073] like Figure 12 As shown, the upper cover 400 includes a top wall 410 and a surrounding wall 420. The surrounding wall 420 extends axially from the edge of the top wall 410 along the upper cover 400. A mounting hole 430 is provided at the end of the surrounding wall 420 away from the top wall 410 for connection. Figure 11 The wall of the mounting hole 430 is detachably connected to the mounting base 280. Specifically, as shown... Figure 11 As shown, the wall of the mounting hole 430 can be directly snapped onto the mounting base 280 to achieve a detachable connection. Alternatively, threads can be provided on the wall of the mounting hole 430 to achieve a threaded connection with the mounting base 280.

[0074] like Figure 12As shown, the recess 401 includes a first groove 4011 and a second groove 4012 that communicate with each other. The first groove 4011 is disposed on the surrounding wall 420 and extends axially along the upper cover 400, and the second groove 4012 is disposed on the top wall 410 and extends radially along the upper cover 400. Figure 11 and Figure 12 As shown, at least a portion of the handle 303 is housed in the first groove 4011, and at least a portion of the therapy head 302 is housed in the second groove 4012. The first groove 4011 extends axially and the second groove 4012 extends radially. The handle 303 and the therapy head 302 are placed in the first groove 4011 and the second groove 4012 respectively. This allows the handle 303 of the therapy device 300 to be placed vertically, making fuller use of the relatively long but narrow pressing space A along the axial direction to accommodate the elongated handle 303, resulting in higher space utilization.

[0075] In one embodiment, such as Figure 12 As shown, a limiting protrusion 4013 is provided at the transition between the first groove 4011 and the second groove 4012. (As indicated...) Figure 11 As shown, the handle 303 and the therapy head 302 are connected at an angle β, as... Figure 10 As shown, an insertion space 304 is formed at the connection between the handle 303 and the therapy head 302. Combined with... Figure 11 and Figure 12 As shown, the limiting protrusion 4013 engages with the insertion space. This allows the physiotherapy device 300 to hang on the upper cover 400 like a hook, serving to limit and fix it.

[0076] Furthermore, a magnetic structure can be provided between the top cover 400 and the handle 303 to magnetically hold the physiotherapy device 300 in place, further securing the device and preventing it from falling. In this embodiment, as shown... Figure 11 As shown, the phototherapy lamp panel 310, battery 320, button 330, and charging post 340 are located on the therapy head 302 of the physiotherapy device 300. This eliminates the need for parts in the handle 303, allowing for a smaller cross-sectional design that facilitates insertion into the recess 401 of the top cover 400. Figure 10 As shown in the embodiment of this application, the physiotherapy device 300 can be made into the shape of an earphone.

[0077] In this embodiment, the push-pump assembly 200 can employ any type of push-pump body. In one embodiment, such as... Figure 3 and Figure 4 As shown, the press pump assembly 200 also includes a sleeve 210, a piston rod 220, a tube 260, a plug 230, a valve body 240, and an elastic element 250.

[0078] like Figure 7The piston rod 220 has a pressing end 2201 and a piston end 2202. (Combined) Figure 4 and Figure 7 The pressing end 2201 of the piston rod 220 is connected to the movable member 100. One end of the tube 260 is connected to the movable seat 280, and the other end extends into the sleeve 210 and is fitted over the piston rod 220. Specifically, a cap 270 is connected to the top of the tube 260, and the cap 270 is inserted into the movable member 100. When the movable member 100 is pressed, the tube 260 and the piston rod 220 can be pushed downward synchronously. After the movable member 100 is released, the piston rod 220 is reset under the action of the elastic member 250, realizing the pump suction operation.

[0079] like Figure 4 As shown, the end of the sleeve 210 furthest from the applicator head 110 is provided with a liquid inlet 201. (As indicated...) Figure 4 As shown, the piston end 2202 of the piston rod 220 extends into the sleeve 210. (As indicated...) Figure 4 As shown, a pump suction chamber 211 is formed between the piston end 2202 of the piston rod 220 and the bottom of the sleeve 210. (This is in conjunction with...) Figure 7 As shown, the side wall of the piston rod 220 is provided with a connecting hole 222, which, combined with... Figure 4 and Figure 7 The connecting hole 222 connects the second liquid outlet channel 221 of the piston rod 220 with the inner cavity of the sleeve 210.

[0080] A plug 230 is disposed within the sleeve 210 and sleeved on the outside of the piston rod 220, and the plug 230 seals the gap between the piston rod 220 and the sleeve 210. The piston rod 220 has a first unpressed position (e.g., ...). Figure 4 (As shown), the second position during the pressing process and the third position when pressed all the way down. Figure 4 As shown, when the piston rod 220 is in the first position, that is, when the piston rod 220 is in the initial position, the plug 230 seals the connecting hole 222. When pressing begins, the piston rod 220 begins to move downwards, while the plug 230 remains stationary. When the piston rod 220 is in the second position, the plug 230 separates from the connecting hole 222, thereby connecting the connecting hole 222 to the second liquid outlet channel 221. At this time, the fitting 260 abuts against the plug 230, pushing the plug 230 downwards together, squeezing the air in the pump suction chamber 211. The air is discharged through the connecting hole 222 and the second liquid outlet channel 221 of the plug 230, creating a vacuum in the pump suction chamber 211. The skin care liquid can then enter the pump suction chamber 211 and flow out through the connecting hole 222 and the second liquid outlet channel 221.

[0081] Continue to refer to Figure 7The piston end 2202 of the piston rod 220 (i.e., the end of the piston rod 220 near the valve body 240) has a plug 223. The size of the plug 223 is larger than the size of the main body of the piston rod 220, thus forming a larger plug 223 at the head of the piston rod 220. When the piston rod 220 moves upward, the plug 223 drives the plug portion 230 to return to its original position. Figure 4 The side wall of the plug 223 abuts against the inner wall of the sleeve 210, such as Figure 7 The stopper 223 has a through groove 2231 that penetrates the side wall of the stopper 223 and extends axially along the stopper 223. Multiple through grooves 2231 can be provided, arranged at intervals along the circumference of the stopper 223. The through groove 2231 allows gas and skin care liquid to enter the connecting hole 222 through the gas passage 2231, then enter the second liquid outlet channel 221, and finally flow out.

[0082] like Figure 4 The valve body 240 is located at the bottom end of the sleeve 210. The valve body 240 is configured to open into the sleeve 210 when a negative pressure is formed in the sleeve 210, so that the skin care liquid can enter the pump suction chamber 211 through the valve body 240.

[0083] like Figure 4 As shown, the elastic element 250 is used to drive the piston rod 220 to return to its original position after the piston rod 220 has been pressed. The elastic element 250 can be a spring or other elastic element. Figure 4 In the illustrated embodiment, one end of the elastic element 250 abuts against the tube 260, and the other end of the elastic element 250 abuts against the sleeve 210. Specifically, a bushing 290 is fitted onto the inner top ring of the sleeve 210, and the elastic element 250 abuts against the bushing 290. When the movable element 100 is pressed, the piston rod 220 moves downward, and the elastic element 250 is compressed. When the movable element 100 is released, the elastic element 250 returns to its original position, causing the piston rod 220 to return to its original position.

[0084] In other embodiments, such as Figure 6 As shown, the elastic element 250 can also be disposed inside the sleeve 210 and between the sleeve 210 and the piston rod 220. Specifically, as... Figure 6 An elastic element 250 is disposed in the pump suction chamber 211. One end of the elastic element 250 abuts against the bottom end of the piston rod 220, and the other end of the elastic element 250 abuts against the bottom of the sleeve 210. When the piston rod 220 is pressed, the elastic element 250 is compressed. When the piston rod 220 is released, the piston rod 220 is reset under the elastic force of the elastic element 250.

[0085] In this embodiment of the application, combined with Figure 4 and Figure 7 The working process of the press pump assembly 200 is as follows:

[0086] like Figure 4 As shown, when the piston rod 220 is in the initial position (first position), 230 closes the connecting hole 222 on the piston rod 220;

[0087] When the movable part 100 is pressed, the movable part 100 pushes the cap 270, the tube 260 and the piston rod 220 to move downward together. The piston rod 220 moves from the first position to the second position. The connecting hole 222 on the piston rod 220 is released from the seal of the plug 230. The air in the pump suction chamber 211 enters the second liquid outlet channel 221 in the piston rod 220 through the air passage 2231 on the piston rod 220 plug head 223 and the connecting hole 222 on the piston rod 220. The air then enters the first liquid outlet channel 111 of the applicator head 110 through the second liquid outlet channel 221 and is finally discharged to the outside.

[0088] When the pressure is continued, the piston rod 220 moves from the second position to the third position. During this process, air is continuously discharged from the pump suction chamber 211, and a vacuum is formed in the pump suction chamber 211.

[0089] After pressing repeatedly to expel air, the pump suction chamber 211 reaches a certain vacuum. The valve body 240 is opened under the vacuum in the pump suction chamber 211, and the skin care liquid enters the pump suction chamber 211 from the liquid inlet 201 at the bottom of the sleeve 210. When pressed again, the skin care liquid in the pump suction chamber 211 enters the second liquid outlet channel 221 in the piston rod 220 through the air passage 2231 and the connecting hole 222 on the piston rod 220, and finally enters the applicator head 110 and flows out.

[0090] In this embodiment, the valve body 240 can be any type of valve body 240 that can open into the sleeve 210 when a negative pressure is formed in the sleeve 210. In a specific embodiment, such as... Figure 8 As shown, the valve body 240 includes an outer ring 241, a plug 242, and a connecting rib 243. The plug 242 is disposed within the outer ring 241, and the connecting rib 243 connects the plug 242 and the outer ring 241. The connecting rib 243 is relatively thin, making it easy to deform under pressure, causing the plug 242 to disengage from the inlet 201 of the sleeve 210, thus opening the inlet 201. Figure 4 and Figure 8 When the piston rod 220 is pressed downwards, the plug 242 cannot open downwards because it is pressed against the inlet 201, thus preventing gas from escaping downwards from the pump suction chamber 211. When a vacuum is formed in the pump suction chamber 211, the plug 242 opens upwards, allowing the skin care liquid to enter the pump suction chamber 211. The valve body 240 can be made of soft rubber material, such as polyethylene.

[0091] Understandable, such as Figure 4 As shown, the cap 270 is provided with a liquid channel 271 corresponding to the second liquid outlet channel 221 of the piston rod 220. (Reference) Figure 4The pump suction chamber 211, the second liquid outlet channel 221 in the piston rod 220, and the liquid channel 271 in the cap 270 together form the liquid outlet channel of the press pump assembly 200.

[0092] This application also discloses a skincare product container 20. For example... Figure 13 and Figure 14 As shown, the skincare product container 20 includes a bottle body 21 and the aforementioned application device 10. (As...) Figure 14 As shown, the applicator 10 is fitted onto the bottle body 21, thereby sealing the opening at the top of the bottle body 21. The mounting base 280 of the applicator 10 is detachably connected to the bottle body 21 to facilitate the refilling of skincare products into the bottle. Figure 4 As shown, the mounting base 280 is provided with a thread 281, and the mounting base 280 is threadedly connected to the bottle body 21 via the thread 281. Figure 14 As shown, the inlet 201 of the pump assembly 200 is connected to the inner cavity of the bottle body 21, so that the skin care liquid in the bottle body 21 flows into the pump assembly 200 from the inlet 201, then enters the applicator head 110 from the pump assembly 200, and finally flows out from the applicator head 110.

[0093] Figure 15 This is a skincare product container 20 according to another embodiment of this application. Figure 15 In the skin care product container 20 shown, the application device 10 includes a top cover 400 and a physiotherapy device 300.

[0094] Since the skin care product container 20 of this application includes the above-mentioned application device 10, it has at least the beneficial effects of the above-mentioned application device 10, which will not be repeated here.

[0095] The technical features in the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above 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.
