Description

Technical Field

[0001] The present application relates to the field of cosmetics, and in particular to a cosmetic container with an improved structure for discharging viscous materials by pressing. Background Art

[0002] Traditional lipsticks often adopt a rotating or pull-out design. Users need to rotate or pull to expose the lipstick gel for use, which is relatively cumbersome. In recent years, some push-type lipsticks have appeared on the market. For example, a push-and-pop lipstick tube structure is disclosed in a Chinese patent document with a publication number of CN213524236U, and specifically discloses an outer cover, a ratchet cover, a guide wheel, a ratchet seat and a middle bundle core; the ratchet cover is provided with a lower jumping ratchet slideway, the guide wheel is coaxially connected to the ratchet cover through a spring, the side circumferential wall of the guide wheel is provided with a side sliding block, the ratchet seat is provided with an upper ratchet slideway, and the upper ratchet slideway includes a ratchet bevel and a straight groove; the side sliding block is located between the lower jumping ratchet slideway and the upper ratchet slideway.

[0003] In the above-mentioned related technology, by pressing the center bundle core, the spring is compressed and then force is transmitted to rotate the guide wheel, thereby changing the position of the side sliding block. When the side sliding block moves to the lowest end of the bevel of the lower jumping ratchet slide, it can no longer rotate. At this time, the center bundle core is released. Under the elastic force of the spring, the side sliding block moves up and slides along the bevel of the ratchet, and then slides into the straight groove. The spring continues to push the guide wheel and the ratchet seat to move, thereby ejecting the center bundle core. At this time, lipstick can be applied.

[0004] Although the operation of the above patent is relatively simple, the pushing out and resetting of the lipstick are completely dependent on the compression and rebound of the spring. The spring is extremely easy to fatigue. Once the lipstick paste is viscous, it is easy to cause insufficient pressing force and fail to discharge the material in a short time. In addition, due to the inability to discharge the material, the pressing force is increased, resulting in too much material being discharged at one time. In the long run, this leads to the problem of mismatch between the pressing force and the amount of lipstick pushed out, so this problem needs to be solved urgently. Summary of the invention

[0005] In order to improve the problem of non-linear material ejection amount of existing lipstick pens when pressed, the present application provides a cosmetic container with an improved pressing and discharging structure for viscous materials.

[0006] The present application provides a cosmetic container with an improved structure for discharging viscous materials by pressing, which adopts the following technical solution: A cosmetic container with an improved viscous material pressing and discharging structure, comprising a pen body for accommodating the viscous material, wherein a pressing cover is arranged inside the pen body, and the pressing cover moves along the length direction of the pen body; The pen body is provided with a push sleeve, a nut, a stop ring and a piston in sequence along its axial direction, and the push sleeve and the nut are both located in the pen body and rotate without generating axial displacement; A screw is also provided in the pen body, one end of the screw is located in the pressing cover, and the other end passes through the pushing sleeve, the nut and the stop ring in sequence and is connected to the piston, the screw is threadedly connected to the nut, and the stop ring is relatively fixed to the pen body; The pressing cover is provided with a return spring sleeved on the outside of the screw rod, one end of the return spring abuts against the pushing sleeve, and the other end abuts against the inner cover surface of the pressing cover, and the return spring is used for the pressing cover to rebound and reset after the material is pressed out; When the pressing cover is pressed down, the pressing cover drives the sleeve to rotate through the component force of the downward pressure, and drives the nut and the stop ring to rotate synchronously, and the piston slides adaptively on the inner side of the pen body and pushes the viscous material out; When the pressing cover rebounds, the pushing sleeve rotates in the opposite direction and releases the synchronous rotation with the nut. At this time, the limiting ring limits the rotation of the screw nut.

[0007] By adopting the above technical solution, when the pressing cover is pressed, the pushing sleeve will be driven to rotate by the downward pressure component of the pressing cover and drive the nut to rotate. The rotation of the nut will drive the screw to rotate. However, under the limiting action of the limit ring, the screw cannot rotate and is converted into linear motion under the action of the threaded structure. Then, the piston is pushed to move in the pen body through the screw to realize material discharge.

[0008] During the whole process of discharging, although the return spring will be compressed when the pressing cover is pressed down, since the downward thrust of the piston comes directly from the downward force of the pressing cover, the return spring does not participate in the direct force transmission in the design of the piston's downward thrust, but only plays the role of rebounding the pressing cover. Therefore, compared with the above-mentioned related technologies, the requirements for the return spring's rebound force can be reduced, thereby effectively reducing the fatigue damage of the return spring.

[0009] Optionally, the pressing cover is provided with a spiral guiding inclined groove along the axial direction of its outer wall, and the outer wall of the pushing sleeve is provided with a guiding block located in the guiding inclined groove; When the pressing cover is pressed or rebounded, the sliding block adaptively slides in the guiding inclined groove.

[0010] By adopting the above technical solution, since the pressing cover can only move axially and the pushing sleeve cannot move axially, when the pressing cover is pressed, the pushing sleeve will be restricted by the cooperation of the guide block and the guide bevel groove to rotate, thereby driving the nut to rotate.

[0011] Optionally, a convex ring is provided on the outer wall of the nut, and an annular groove is provided on the inner wall of the pen body. The convex ring is adaptively clamped in the groove, and the convex ring can rotate around its own axis in the groove.

[0012] By adopting the above technical solution, the cooperation between the convex ring and the groove can fix the horizontal and vertical positions of the nut without hindering the normal rotation of the nut, thereby ensuring that the vertical movement of the screw can be achieved by pushing the rotation of the sleeve.

[0013] Optionally, a positioning strip is provided on the outer wall of the limit ring, a positioning slot is provided on the inner wall of the pen body, and the positioning strip is inserted into the positioning slot.

[0014] By adopting the above technical solution, with the cooperation of the positioning strip and the positioning slot, the limit ring is in a fixed state, thereby ensuring that the limit ring provides a limiting effect on the screw and enables the rotation of the screw to be converted into its own vertical movement.

[0015] Optionally, a plurality of positioning slots are evenly arranged along the circumference of the pen body.

[0016] By adopting the above technical solution, the positioning ring can be positioned by inserting the positioning strip into any positioning slot, which facilitates the operation.

[0017] Optionally, a first notch is provided on the pushing sleeve, and the first notch extends to the end of the pushing sleeve facing the nut. A lower jumping pawl is formed at the opening of the first notch, and an upper ratchet that cooperates with the lower jumping pawl is provided on the nut. The lower jumping pawl can produce elastic deformation and bend into the first notch.

[0018] By adopting the above technical solution, when the cover is pressed down to press out the material, the sleeve is pushed to rotate forward, and the lower jumping pawl and the upper ratchet are in a clamping state. When the cover is pressed back, the lower jumping pawl can rebound into the first notch and be in a jumping tooth state.

[0019] Optionally, a second notch is provided on the limiting ring, and the second notch extends to the end of the limiting ring facing the nut. An upper jumping pawl is formed at the opening of the second notch, and a lower ratchet that cooperates with the upper jumping pawl is provided on the nut. The upper jumping pawl can produce elastic deformation and bend into the second notch.

[0020] By adopting the above technical solution, when the cover is pressed down to press out the material, the upper jumping pawl and the lower ratchet are in a clamping state, and when the cover is pressed back, the upper jumping pawl can be deformed and rebound into the second notch and be in a jumping tooth state.

[0021] Optionally, a limiting plane is provided on the outer wall of the screw, a limiting hole is provided on the limiting ring, the screw passes through the limiting hole and passes through the limiting ring, and the screw is restricted by the limiting plane and the limiting hole and is located in the pen body without generating rotational movement.

[0022] By adopting the above technical solution, the cooperation between the limiting plane and the limiting hole ensures that the screw cannot rotate in the limiting hole, thereby realizing the limiting effect of the limiting ring on the screw.

[0023] In summary, this application has the following beneficial effects: 1. The reset spring is only used to reset the pressing cover, not to generate lateral force for the rotation of the nut, which reduces the rebound pressure of the reset spring, thereby delaying the fatigue of the reset spring and improving the pressing feel.

[0024] 2. All parts involved in the entire pressing and discharging structure are independent assembly components, which is not only easier to form during mold opening, but also can be installed independently during assembly, which is convenient for operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-7 This application is described in further detail.

[0034] See also Figure 1 and Figure 2 A cosmetic container with improved viscous material pressing and discharging structure comprises a pen body 1, a pen cap 2 and a middle bundle core 4, the middle bundle core 4 is used to hold cosmetic paste, a mounting ring 41 is provided in the middle of the outer wall of the middle bundle core 4, the pen body 1 is sleeved on the upper outer side of the middle bundle core 4, and the pen cap 2 is sleeved on the lower outer side of the middle bundle core 4.

[0035] See also Figure 2 and Figure 3 A first insert strip 42 is provided on the outer wall of the middle bundle core 4 and above the mounting ring 41, and a first slot 11 is provided on the inner wall of the pen body 1. When installing the middle bundle core 4, the middle bundle core 4 is inserted into the pen body 1, and the first insert strip 42 is correspondingly inserted into the first slot 11, so that the pen body 1 is fixed relative to the middle bundle core 4, and the two are in a tight fit. A rubber ring 43 is embedded on the outer wall of the middle bundle core 4 and below the mounting ring 41, and two mounting ridges 44 are integrally formed. A mounting protrusion 21 is integrally formed on the inner wall of the pen cap 2, and the pen cap 2 is in a pluggable state relative to the middle bundle core 4. When the pen cap 2 is sleeved on the lower part of the middle bundle core 4, the mounting protrusion 21 can slide over the mounting ridge 44, so that the pen cap 2 will not slide off easily. At the same time, the rubber ring 43 will also be tightly pressed between the outer wall of the middle bundle core 4 and the inner wall of the pen cap 2, so that when the cosmetic container is not in use, the pen cap 2 and the middle bundle core 4 are still in a sealed state.

[0036] See also Figure 2 The pen body 1, the pen cap 2 and the middle bundle core 4 are all in a hollow tubular shape. A pen tail 12 is tightly inserted at one end of the pen body 1 away from the pen cap 2. A second insertion strip 121 is provided on the outer wall of the pen tail 12. A second slot 15 for inserting the second insertion strip 121 is provided on the inner wall of the pen body 1 near its upper part. A pressing cover 3 is inserted in the pen tail 12. The upper part of the pressing cover 3 protrudes above the pen tail 12. A pair of sliding blocks 32 are provided at the lower part of the pressing cover 3. A pair of sliding grooves 120 extending in the vertical direction are provided on the inner wall of the pen tail 12. When the pressing cover 3 is installed in the pen tail 12, the pair of sliding blocks 32 are adaptively located in the pair of sliding grooves 120, thereby ensuring that the pressing cover 3 can only move in the vertical direction and facilitating the rapid positioning and assembly of the pressing cover 3 and the pen tail 12.

[0037] See also Figure 2The lower part of the pressing cover 3 is also provided with two sections of spiral guide chute 33 along the axial direction of its outer wall. A push sleeve 5 is sleeved on the inner side of the pressing cover 3. The push sleeve 5 is a hollow structure. Two guide blocks 51 are provided on the outer wall of the pushing sleeve 5. The two guide blocks 51 are respectively and one-to-one arranged in the two guide chute 33. The size of the guide blocks 51 is adapted to the groove width of the guide chute 33. When the pressing cover 3 moves up and down, the sliding block 32 slides in the slide groove 120 adaptively, and the guide block 51 slides from one side of the guide chute 33 to the other side of the guide chute 33. Since the guide chute 33 is arranged in a spiral shape, the pushing sleeve 5 will rotate in the pen body 1 at this time. The cooperation of the guide chute 33 and the guide block 51 can facilitate the positioning and assembly of the pushing sleeve 5 and the pressing cover 3. At the same time, the pressing cover 3 is a cylindrical open design with one end open, has good deformation ability and simple structural design, and is also relatively simple when installing the pushing sleeve 5. At the same time, a certain distance is left between the sliding block 32 on the pressing cover 3 and the guiding bevel groove 33. When the pressing cover 3 is molded, the material used to fill the mold to form the sliding block 32 is not easy to accumulate too much in the guiding bevel groove 33, which can reduce the burrs in the guiding bevel groove 33 and thus improve the reliability of the pushing sleeve 5 and the pressing cover 3 when they move in coordination.

[0038] See also Figure 2 and Figure 3 The pen body 1 is provided with a nut 6, a screw 7, a stop ring 8 and a piston 9. The screw 7 is inserted into the push sleeve 5. One end of the screw 7 is located on the inner side of the pressing cover 3. The other end of the screw 7 is connected to the piston 9. The outer wall of the piston 9 is connected to the inner wall of the middle beam core 4. The piston 9 can push the material in the middle beam core 4 to discharge the material. A convex ring 62 is provided on the outer wall of the nut 6. An annular groove 13 is provided on the inner wall of the pen body 1. The convex ring 62 is adaptively clamped in the groove 13. The convex ring 62 can rotate around its own axis in the groove 13. In this way, the nut 6 cannot move axially or radially, but can still rotate normally. A plurality of positioning strips 83 are provided on the outer wall of the stop ring 8. A plurality of positioning slots 14 are also provided on the inner wall of the pen body 1. The plurality of positioning strips 83 are respectively and one-to-one arranged in the plurality of positioning slots 14. In this way, the stop ring 8 is in a tightly matched connection state with the pen body 1 after assembly. After all parts are installed, the pen tail 12 and the retaining ring 8 cannot move or rotate, the pushing sleeve 5 and the nut 6 cannot move axially but can rotate around their own axes, and the piston 9 will not rotate but can move along its own axial direction.

[0039] See also Figure 4 and Figure 5The top of the nut 6 is provided with an upper ratchet 61, and the bottom is provided with a lower ratchet 63, wherein the upper ratchet 61 is flatly distributed along the circumferential direction of the nut 6, and a step is formed at the connection between two adjacent ratchet teeth; the bottom of the push sleeve 5 is provided with a lower jumping pawl 52 and a first notch 53, and the first notch 53 is located above the lower jumping pawl 52, so that the lower jumping pawl 52 is in a cantilever state and can be deformed toward the first notch 53 by external force. The lower jumping pawl 52 can be offset against the step formed at the connection between two adjacent ratchet teeth in the upper ratchet 61 to achieve the same direction rotation of the push sleeve 5 and the nut 6. When the push sleeve 5 and the nut 6 rotate in the opposite direction, the tooth surface contact portion of the lower jumping pawl 52 and the upper ratchet 61 is provided with a wedge surface, and the entire lower jumping pawl 52 will be squeezed and deformed. At this time, rotation interference will occur between the lower jumping pawl 52 and the upper ratchet 61, so that the push sleeve 5 and the nut 6 do not affect each other when they rotate in the opposite direction.

[0040] See also Figure 4 and Figure 5 The top of the stop ring 8 is provided with an upper jumping pawl 81 and a second notch 82, and the second notch 82 is located below the upper jumping pawl 81. In this way, the upper jumping pawl 81 is also in a cantilever state and can be deformed toward the second notch 82 by external force. When the push sleeve 5 and the nut 6 rotate in the same direction, the lower jumping pawl 52 can move along the tooth tip of the upper ratchet 61 without interfering with each other. When the push sleeve 5 and the nut 6 rotate in the opposite direction, the upper jumping pawl 81 will move to abut against a certain tooth root of the lower ratchet 63, thereby limiting the rotation of the nut 6.

[0041] See also Figure 6 and Figure 7 The outer wall of the screw rod 7 is provided with an external thread 71, and a pair of oppositely arranged limiting planes 72 are also provided on the outer wall of the screw rod 7. A limiting hole 84 is provided on the top of the limiting ring 8. The screw rod 7 passes through the limiting ring 8 through the limiting hole 84. The limiting hole 84 is square, and the pair of limiting planes 72 fit with the inner wall of the limiting hole 84. A reset spring 31 is sleeved on the top of the screw rod 7, and the two ends of the reset spring 31 abut between the top of the push sleeve 5 and the inner top of the pressing cover 3.

[0042] The working process of the present application when in use is specifically as follows: when the material body is not needed to be discharged, the pen cap 2 is sleeved on the outer side of the lower part of the middle bundle core 4, and the distance between the mounting ring 41 and the lower end surface of the middle bundle core 4 is smaller than the length of the pen cap 2. If lipstick is contained in the middle bundle core 4, the lipstick in the middle bundle core 4 will not contact the pen cap 2.

[0043] When it is necessary to discharge the material, the pen cap 2 is removed, and then the pressing cover 3 is pressed downward. Due to the cooperation restriction of the sliding block 32 and the slide groove 120, there will be extrusion between the guide block 51 and the guide bevel groove 33, so that the guide block 51 slides along the bottom end of the guide bevel groove 33 to the top end of the guide bevel groove 33. In this process, the push sleeve 5 will rotate, that is, the lateral force for the push sleeve 5 to rotate directly comes from the oblique component force of the pressing cover 3 pressing down. At this time, the lower jumping pawl 52 will counteract the step formed at the connection between the two adjacent ratchet teeth in the upper ratchet 61, and drive the nut 6 and the push sleeve 5 to rotate in the same direction. Because the screw rod 7 and the nut 6 are threadedly connected, after the nut 6 rotates, the screw rod 7 has a tendency to rotate. Under the limiting action of the limiting plane 72, and the limiting ring 8 and the pen body 1 are in a fixed connection state, the rotation of the screw rod 7 will be converted into axial movement, thereby pushing the piston 9 to move downward, and realizing the ejection of the material in the middle bundle core 4. Each time the pressing cover 3 is pressed, the single movement stroke of the piston 9 is the rotation stroke of each tooth of the lower ratchet 63 on the nut 6 .

[0044] After the pressing of the pressing cover 3 is completed, the pressing cover 3 is released. Under the action of the elastic force of the return spring 31, the pressing cover 3 will rebound and reset upward. At this time, the guide block 61 will slide from the top of the guide inclined groove 33 to the bottom of the guide inclined groove 33, and drive the pushing sleeve 5 to rotate in the opposite direction. At this time, the lower jumping pawl 52 will deform and rebound under the action of the first notch 53, and move along the tooth surface of the upper ratchet tooth 61. At the same time, under the action of the second notch 82, the upper jumping pawl 81 will also be elastically deformed and bend toward the second notch 82. At this time, the upper jumping pawl 81 jumps on the lower ratchet tooth 63 and moves to the next tooth root of the lower ratchet tooth 63 and presses tightly to limit the rotation of the nut 6, so that the nut 6 can remain in a relatively static state. While realizing the reset of the pushing sleeve 5, it will not affect the position of the screw rod 7, ensuring that the screw rod 7 can move again by the same distance when pressed next time, ensuring the discharge amount of the material discharged by one press.

[0045] Since the return spring 31 is arranged on the upper part of the screw rod 7, when the return spring 31 releases energy and rebounds, it only needs to bear the rebound force of the pressing cover 3 to reset, and the required elastic force is relatively small. The movement of the piston 9 is achieved through the cooperation of the pressing cover 3, the pushing sleeve 5 and the nut 6. The downward thrust of the piston 9 is directly derived from the downward pressure of the pressing cover 3. The return spring 31 does not participate in the direct force transmission during the downward pushing action of the piston 9, thereby greatly reducing the workload of the return spring 31 and ensuring that the return spring 31 can push the pressing cover 3 to reset completely, so that each press of the pressing cover 3 by the user can cause the pressing cover 3 to produce the same displacement, and the corresponding discharge amount is also the same, which significantly improves the user experience.

[0046] The cosmetic container in the present application is suitable for solidified pastes such as lipstick sticks, and is also suitable for viscous pastes such as hair removal wax.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
