Description

Technical Field

[0001] This utility model relates to the field of cosmetic technology, and specifically to a press-apply container. Background Technology

[0002] Cosmetics are used to enhance, preserve, or alter a person's appearance. They come in various types, including liquid and powder containers, where the product is liquid, such as liquid setting powder, foundation, and concealer. These traditional liquid and powder containers mainly fall into three categories: pump dispensers, cushion compacts, and tubes. However, all of these require an application tool, such as a powder puff, to apply the product. Pump dispensers and tube compacts come with separate puffs, leading to the possibility of spills or misplacements. While cushion compacts have built-in puffs, they are separate and not connected to other parts, also resulting in potential spills. Furthermore, since application tools are handheld, product inevitably gets on hands during application, requiring hand cleaning. Summary of the Invention

[0003] The purpose of this utility model is to provide a press-to-apply container. By connecting an applicator head to the main body, the makeup tool is directly connected to the main body, so there will be no leakage or spillage. Furthermore, by pressing to dispense the product and allowing the product to go directly to the applicator head, the product is prevented from sticking to the hands. Therefore, this solves the problems of leakage or spillage when using a separate powder puff and the product sticking to the hands when holding the powder puff.

[0004] The purpose of this utility model is achieved as follows:

[0005] A press-apply container includes a main body, with a movable pressing element at one end of the main body and an applicator connected to the other end of the main body. The applicator and the pressing element form a chamber for placing the material, and a movable piston is placed inside the chamber. The end of the main body connected to the applicator has a discharge port. The movement of the pressing element changes the air pressure inside the chamber, thereby driving the piston to move and pushing the material to the discharge port and onto the applicator.

[0006] Alternatively, the pressing element is connected to and moves synchronously with the piston. The movement of the pressing element drives the piston to move, and the piston pushes the material to the outlet and onto the coating head.

[0007] Preferably, the piston has a slot at its top and a mounting post at the bottom of the pressing member, with the end of the mounting post away from the pressing member located in the slot.

[0008] Preferably, the main body has a built-in card holder, which is located between the pressing member and the applicator head. The space between the card holder and the applicator head is a chamber, and the piston is located between the card holder and the applicator head. The card holder has a corresponding mounting post opening, and an elastic member is provided between the card holder and the pressing member. The elastic member is used to reset the moving pressing member.

[0009] Preferably, the main body has a built-in card seat, which is located between the pressing member and the applicator head. The card seat has an opening to allow air to circulate up and down. The space between the card seat and the applicator head is a chamber, and a piston is located between the card seat and the applicator head. By pressing the pressing member inward, the air pressure in the chamber is changed, thereby driving the piston to move.

[0010] An elastic element is provided between the card holder and the pressing element, and the elastic element is used to reset the pressed element after it has been moved. The pressing element has at least one air hole that communicates with the cavity. The air hole connects the inside and outside to balance the internal and external air pressure, so that the piston is always in contact with the material.

[0011] Preferably, a one-way valve is provided between the chamber and the outlet, and the one-way valve is used to prevent material backflow.

[0012] Preferably, the one-way valve includes a housing with openings at both ends, the top opening of the housing communicating with the chamber, a valve core built into the top of the housing, and the bottom opening of the housing communicating with the discharge port. The valve core is elastic, and a blocking part is provided in the middle of the valve core. A hole is provided on the outside of the blocking part of the valve core. The blocking part is located inside the top opening of the housing, so that the hole is not communicating with the chamber. The blocking part moves under force, so that the hole communicates with the chamber.

[0013] Preferably, the bottom of the pressing component is provided with a second retainer, and the second retainer is sleeved on the outside of the outer shell. The pressing component and the one-way valve are in a chamber, and the piston is located between the pressing component and the one-way valve. The pressing component has at least one air hole that communicates with the chamber. The air hole connects the inside and outside to balance the internal and external air pressure, thereby ensuring that the piston is always in contact with the material.

[0014] The one-way valve also includes a discharge component, and there is a storage area between the discharge component and the valve core. The discharge component has a channel in the middle for connecting the discharge port and the storage area. The top of the discharge component is located inside the housing and has a side opening that communicates with the channel. A piston is provided between the discharge component and the housing, and the piston is located outside the side opening so that the side opening and the housing are not connected.

[0015] An elastic element is provided between the coating head and the second card holder, and a limiting component is provided between the top of the discharge component and the second piston to restrict the movement of the second piston. By pressing the pressing component inward, the second card holder is moved, which in turn moves the outer shell and the second piston, thereby connecting the side opening and the inside of the outer shell, so that the material in the storage area moves to the discharge port through the discharge component.

[0016] The elastic element resets the moved card seat 2, thereby resetting the moved pressing element. At this time, the outer shell and piston 2 move due to the movement of card seat 2, and piston 2 stops moving due to the limiting component. However, the outer shell continues to move, causing the air pressure in the storage area to change. This causes the blocking part to move due to the air pressure difference, thereby connecting the hole with the chamber. At this time, piston 1 moves the material in the chamber to the storage area through the hole due to the air pressure difference.

[0017] Preferably, the limiting component includes a limiting part, and the part protruding outward from the top of the discharge part is the limiting part, and the top of the piston two abuts against the limiting part to restrict the movement of the piston two.

[0018] Preferably, the main body is provided with a mounting base at one end, and one end of the mounting base is located inside the main body. The mounting base is provided with a mounting component and a protruding plate. The mounting component is provided with a connecting post. The connecting post has a discharge port. The applicator is sleeved on the outside of the connecting post and located between the mounting component and the mounting base. The applicator has a snap-fit ​​groove corresponding to the protruding plate.

[0019] Or / and, the main body is provided with a cap on the outside of the application head.

[0020] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0021] This invention features an applicator head connected to the main body, meaning the makeup tool is directly connected to the main body, thus preventing any leakage or spillage. By moving the pressing component, the material is moved under the action of the piston, moving to the outlet and then to the applicator head for makeup application. Pressing dispenses the material directly to the applicator head, preventing the material from sticking to the hands. Attached Figure Description

[0038] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0039] like Figures 1-9 As shown, a press-apply container includes a main body 1, with a movable pressing member 2 at one end of the main body 1 and an applicator head 3 connected to the other end of the main body 1. The applicator head 3 and the pressing member 2 are connected to a chamber 11 for placing the material. A movable piston 4 is installed inside the chamber 11. A discharge port 91 is provided at the end of the main body 1 connected to the applicator head 3.

[0040] The movement of the pressing component 2 can drive the movement of the piston 4 and allow the piston 4 to push the material to the discharge port 91. Moreover, the movement of the pressing component 2 is done by manually pressing it inward. That is, this utility model adopts pressing discharge.

[0041] Meanwhile, the piston-4 can move in various ways. It can be pushed by pressing, which causes a change in air pressure. That is, the movement of the pressing element 2 changes the air pressure in the chamber 11, thereby driving the piston-4 to move. The piston-4 pushes the material to the outlet 91 and onto the coating head 3.

[0042] Alternatively, the piston 4 and the pressing element 2 can move synchronously, that is, the pressing element 2 and the piston 4 are connected and move synchronously. The movement of the pressing element 2 drives the piston 4 to move, and the piston 4 pushes the material to the discharge port 91 and onto the coating head 3.

[0043] Therefore, in actual use, since the application head 3 is connected to the main body 1, the makeup tool is directly connected to the main body 1, so there will be no leakage or loss. By moving the pressing part 2, the material is moved under the action of the piston 4 and moves to the outlet 91 until it moves to the application head 3, so that makeup can be applied. That is, the material is pressed out and the material is directly applied to the application head 3, thus avoiding the situation of the material sticking to the hands.

[0044] Furthermore, the change in air pressure within chamber 11 is due to the inward movement of the pressing member 2, which alters the volume and thus the pressure. The application head 3 can be a sponge, a brush, or other material that allows the material to pass through and can be used for application. The pressing member 2 has a protrusion 21 in its center, which passes through the main body 1 and protrudes. Therefore, in actual use, the user presses the protrusion 21, causing the pressing member 2 to move inward.

[0045] like Figures 1-9 As shown, the structure between the applicator head 3 and the main body 1 is as follows: First, a mounting base 8 is provided at the end of the main body 1, and one end of the mounting base 8 is located inside the main body 1. The mounting base 8 has a mounting component 9 and a protruding plate 81 inside. A connecting post 93 is provided on the mounting component 9, and the connecting post 93 has a discharge port 91. The applicator head 3 is sleeved on the outside of the connecting post 93 and located between the mounting component 9 and the mounting base 8. The applicator head 3 has a snap-fit ​​groove 31 corresponding to the protruding plate 81.

[0046] Therefore, in actual use, the applicator head 3 is sleeved on the outside of the connecting post 93 and located between the mounting part 9 and the mounting base 8. At this time, the protrusion 81 and the snap-fit ​​groove 31 are compatible, and the mounting part 9 and the applicator head 3 are also provided with a protrusion to increase the contact area.

[0047] Meanwhile, the inner wall of the mounting base 8 is provided with a second protruding ring 82, which is used to limit the position of the mounting part 9. The outer side of the mounting base 8 is provided with a third protruding ring 83, and the inner wall of the main body 1 is provided with an annular groove 3 corresponding to the third protruding ring 83. The connection is achieved by the matching of the third protruding ring 83 and the annular groove 3.

[0048] Secondly, the main body 1 is provided with a cover 20 on the outside of the application head 3 to protect the application head 3. The main body 1 and the cover 20 can be connected by threads, or at least one protrusion 15 is provided on the outside of the main body 1, and an annular groove 2 is provided on the inner wall of the cover 20 corresponding to the protrusion 15. The connection is achieved by the protrusion 15 and the annular groove 2 fitting together.

[0049] like Figures 1-9 As shown, due to the different structures of piston-4 movement, there will be different reset structures, and a one-way valve 7 is also provided to prevent material backflow. Therefore, there are the following three embodiments.

[0050] Example 1: This example uses the movement of piston 4 caused by changes in air pressure, and the reset of pressing element 2 is achieved using elastic element 10, such as... Figures 2-3 As shown, the main body 1 has a built-in card holder 5, which is located between the pressing member 2 and the applicator head 3. The card holder 5 has an opening to allow air to circulate up and down. The space between the card holder 5 and the applicator head 3 is a chamber 11. The piston 4 is located between the card holder 5 and the applicator head 3. An elastic member 10 is provided between the card holder 5 and the pressing member 2. The elastic member 10 is used to reset the moving pressing member 2. The pressing member 2 has at least one air hole 23 that communicates with the inside of the chamber 11.

[0051] The air hole 23 is located at the top of the pressing part 2, and a sealing ring is provided between the pressing part 2 and the main body 1 for airtightness.

[0052] Therefore, in actual use, by pressing the pressing part 2 inward, the air pressure in the chamber 11 is changed, which in turn drives the piston 4 to move. As a result, the material in the chamber 11 is pushed to the outlet 91 by the movement of the piston 4.

[0053] Simultaneously, when the pressing element 2 moves inward, it applies pressure to the elastic element 10. Therefore, when the pressing element 2 stops moving inward, it will reset under the action of the elastic element 10, making it easier to press again. At the same time, when the pressing element 2 moves inward, the air hole 23 is blocked. Therefore, the inward movement will change the air pressure in the chamber 11. At this time, the piston 4 moves and pushes the material to the outlet 91 until it is pushed onto the applicator head 3. When the pressing element 2 stops moving inward, the air hole 23 is no longer blocked, thus connecting the inside and outside and changing the air pressure in the chamber 11, and making the internal and external air pressures equal, so that the piston 4 is always in contact with the material.

[0054] Furthermore, the elastic element 10 can be a metal spring or other elastic body that can perform the same function, and the card holder 5 is provided with a boss, and the metal spring is sleeved on the outside of the boss.

[0055] Meanwhile, the structure between the card holder 5 and the main body 1 is as follows: First, a protruding ring 51 is provided on the outer side of the card holder 5, and an annular groove is provided on the inner wall of the main body 1 corresponding to the protruding ring 51. The connection is achieved by the matching of the protruding ring 51 and the annular groove. Furthermore, a step is provided on the inner wall of the main body 1, and a protruding edge 52 is provided on the outer side of the bottom of the card holder 5. The protruding edge 52 abuts against the step to restrict the position of the card holder 5.

[0056] Example 2: In this example, the movement of piston 4 is caused by synchronous movement, and the reset of pressing element 2 is achieved using elastic element 10, such as... Figures 4-5 As shown, firstly, a slot 41 is provided on the top of the piston 4, and a mounting post 22 is provided at the bottom of the pressing member 2, with the end of the mounting post 22 away from the pressing member 2 located in the slot 41.

[0057] Therefore, in actual use, the connection is achieved by the insertion structure of the mounting post 22 located in the slot 41, thereby achieving synchronous movement. Thus, the pressing part 2 can be reset separately, thereby synchronously driving the piston 4 to reset.

[0058] The specific reset structure is as follows: First, the main body 1 has a built-in card seat 5, and there is a chamber 11 between the card seat 5 and the applicator head 3. The piston 4 is located between the card seat 5 and the applicator head 3. The card seat 5 has an opening corresponding to the mounting post 22, and an elastic element 10 is provided between the card seat 5 and the pressing element 2.

[0059] Therefore, in actual use, by pressing the pressing part 2 inward, the piston 4 is moved, so that the material in the chamber 11 is pushed to the discharge port 91 by the movement of the piston 4.

[0060] At the same time, when the pressing member 2 moves inward, it will apply pressure to the elastic member 10. Therefore, when the pressing member 2 no longer moves inward, the pressing member 2 will be reset under the action of the elastic member 10, so as to facilitate the next pressing. The piston 4 will also be reset as the pressing member 2 is reset.

[0061] Furthermore, the elastic element 10 can be a metal spring or other elastic body that can perform the same function, and the card holder 5 is provided with a boss, and the metal spring is sleeved on the outside of the boss.

[0062] Meanwhile, the structure between the card holder 5 and the main body 1 is as follows: First, a protruding ring 51 is provided on the outer side of the card holder 5, and an annular groove is provided on the inner wall of the main body 1 corresponding to the protruding ring 51. The connection is achieved by the matching of the protruding ring 51 and the annular groove. Furthermore, a step is provided on the inner wall of the main body 1, and a protruding edge 52 is provided on the outer side of the bottom of the card holder 5. The protruding edge 52 abuts against the step to restrict the position of the card holder 5.

[0063] Example 3: This example includes a one-way valve 7, such as... Figures 6-9As shown, a one-way valve 7 is first provided between the chamber 11 and the discharge port 91, and the one-way valve 7 is used to prevent material backflow. Moreover, the one-way valve 7 can be adapted to the discharge structure of Embodiment 3, or other types of one-way valves 7 can be used to adapt to the above two embodiments.

[0064] The one-way valve 7 has various structures. Here, we only describe one structure: First, the one-way valve 7 includes a housing 71 with openings at both ends. The top opening of the housing 71 is connected to the chamber 11. A valve core 72 is built into the top of the housing 71. The bottom opening of the housing 71 is connected to the discharge port 91. The valve core 72 is elastic. A blocking part 721 is provided in the middle of the valve core 72. A hole 722 is provided on the outside of the blocking part 721 of the valve core 72.

[0065] Therefore, in actual use, the blocking part 721 is located in the top opening of the outer casing 71, so that the hole 722 is not connected with the chamber 11, and the blocking part 721 moves under force, so that the hole 722 is connected with the chamber 11.

[0066] Secondly, the relevant structure for material movement is as follows: First, a retainer 6 is provided at the bottom of the pressing member 2, and the retainer 6 is sleeved on the outside of the outer shell 71. A chamber 11 is located between the pressing member 2 and the one-way valve 7, and the piston 4 is located between the pressing member 2 and the one-way valve 7. Furthermore, the pressing member 2 has at least one air hole 23 communicating with the inside of the chamber 11. The air hole 23 is located on the side wall of the pressing member 2, and a gap is provided between the pressing member 2 and the main body 1 to facilitate gas flow.

[0067] Meanwhile, the one-way valve 7 also includes a discharge component 73, and the area between the discharge component 73 and the valve core 72 is a storage area. The discharge component 73 has a channel 731 in the middle for connecting the discharge port 91 and the storage area. The top of the discharge component 73 is located inside the housing 71 and has a side opening 732 that communicates with the channel 731. A piston 74 is provided between the discharge component 73 and the housing 71, and the piston 74 is located outside the side opening 732 so that the side opening 732 and the housing 71 are not connected.

[0068] Furthermore, an elastic element 10 is provided between the applicator head 3 and the card holder 6, and a limiting component for restricting the movement of the piston 74 is provided between the top of the discharge part 73 and the piston 74. The limiting component has the following structure: it includes a limiting part 733, with the outwardly protruding portion of the top of the discharge part 73 being the limiting part 733. The top of the piston 74 abuts against the limiting part 733, thereby restricting the movement of the piston 74. The elastic element 10 can be a metal spring or other elastic body that performs the same function. The card holder 6 has a boss, and the metal spring is sleeved on the outside of the boss.

[0069] Therefore, in actual use, by pressing the pressing part 2 inward, the card seat 6 is moved, which in turn moves the outer shell 71 and the piston 74, thereby connecting the side opening 732 and the inner shell 71, so that the material in the storage area moves to the discharge port 91 through the discharge part 73.

[0070] The elastic element 10 resets the moved card seat 2 6, thereby resetting the moved pressing element 2. At this time, the outer shell 71 and piston 2 74 move due to the movement of the card seat 2 6, and piston 2 74 stops moving due to the limiting component. However, the outer shell 71 continues to move, causing the air pressure in the storage area to change. This causes the blocking part 721 to move due to the air pressure difference, thereby connecting the hole 722 with the chamber 11. At this time, piston 1 4 moves the material in the chamber 11 to the storage area through the hole 722 due to the air pressure difference.

[0071] When the pressing part 2 and the card seat 2 6 are reset, the air hole 23 connects the inside and outside, thereby balancing the internal and external air pressure, so that the piston 4 is always in contact with the material. Moreover, since there is material in the storage area, it balances the air pressure with the chamber 11, thus resetting the blockage part 721.

[0072] Meanwhile, the structure between the card holder 2 6 and the pressing member 2 is as follows: First, the card holder 2 6 is provided with a convex ring 4 61, and the inner wall of the pressing member 2 is provided with an annular groove 4 corresponding to the convex ring 4 61. The connection is achieved by the matching of the convex ring 4 61 and the annular groove 4. Moreover, the structure between the card holder 2 6 and the one-way valve 7 is as follows: First, the inner wall of the card holder 2 6 is provided with a protrusion, and the top of the protrusion is slotted to allow the bottom of the outer casing 71 to be inserted. The protrusion contacts the piston 2 74 and can play a certain driving role when the card holder 2 6 moves upward.

[0073] Secondly, the inner wall of the outer casing 71 is provided with a convex ring 712, which is used to limit the position of the valve core 72. Moreover, the structure between the one-way valve 7 and the applicator head 3 is as follows: firstly, the mounting part 9 is provided with a column 92, and the column 92 is hollow and communicates with the discharge port 91. The end of the discharge part 73 that passes through the outer casing 71 and is exposed is located inside the column 92 and connected to the column 92.

[0074] like Figures 1-9 As shown, each of these three embodiments has its own advantages and disadvantages. For example, the advantages of Embodiment 1 and Embodiment 2 are that their structures are relatively simple and have fewer parts, resulting in lower production costs. However, in Embodiment 1, the consumer needs to press the air hole 23 to discharge the material, and Embodiment 2 has a backflow phenomenon. Embodiment 3 does not have the disadvantages of Embodiments 1 and 2, but its structure is more complex.

[0075] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.

The bottom opening of the housing (71) is connected to the discharge port (91). The valve core (72) is elastic. A blocking part (721) is provided in the middle of the valve core (72). A hole (722) is provided on the outside of the blocking part (721) of the valve core (72). The blocking part (721) is located in the top opening of the housing (71), so that the hole (722) is not connected to the chamber (11). The blocking part (721) moves under force, so that the hole (722) is connected to the chamber (11).

7. A press-apply container according to claim 6, characterized in that: The bottom of the pressing member (2) is provided with a second card seat (6), and the second card seat (6) is sleeved on the outside of the outer shell (71). There is a chamber (11) between the pressing member (2) and the one-way valve (7), and the piston (4) is located between the pressing member (2) and the one-way valve (7). The pressing member (2) has at least one air hole (23) that communicates with the inside of the chamber (11). The air hole (23) connects the inside and outside to balance the internal and external air pressure, so that the piston (4) is always in contact with the material. The one-way valve (7) also includes a discharge component (73), and the area between the discharge component (73) and the valve core (72) is a storage area. The discharge component (73) has a channel (731) in the middle for connecting the discharge port (91) and the storage area. The top of the discharge component (73) is located inside the outer shell (71) and has a side opening (732) that communicates with the channel (731). A piston (74) is provided between the discharge component (73) and the outer shell (71), and the piston (74) is located outside the side opening (732) so that the side opening (732) and the inner shell (71) are not connected. An elastic element (10) is provided between the coating head (3) and the card seat (6), and a limiting component for restricting the movement of the piston (74) is provided between the top of the discharge part (73) and the piston (74). By pressing the pressing part (2) inward, the card seat (6) is moved, and the outer shell (71) and the piston (74) are moved, thereby connecting the side opening (732) and the inner shell (71), so that the material in the storage area moves to the discharge port (91) through the discharge part (73); And the movable card seat (6) is reset by the elastic element (10), thereby resetting the movable pressing element (2). At this time, the outer shell (71) and the piston (74) move due to the movement of the card seat (6), and the piston (74) stops moving due to the limiting component. However, the outer shell (71) still moves and causes the air pressure in the storage area to change, thereby causing the blocking part (721) to move due to the air pressure difference, and then the hole (722) to connect with the chamber (11). At this time, the piston (4) moves the material in the chamber (11) to the storage area through the hole (722) due to the air pressure difference.

8. A press-apply container according to claim 7, characterized in that: The limiting component includes a limiting part (733), and the part of the top of the discharge part (73) that protrudes outward is the limiting part (733), and the top of the piston (74) abuts against the limiting part (733) to restrict the movement of the piston (74).
