Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cosmetics, in particular to a cosmetic bottle that can be quickly opened and closed. Background Art
[0002] Existing cosmetics such as lip gloss and mascara are usually packaged in bottles with a relatively small diameter. The upper end of such a bottle is provided with an opening, and a detachable bottle cap is provided at the opening. The bottle cap is provided with a dipping rod for dipping lip gloss or mascara. The existing bottle cap is connected to the bottle mouth by a thread, and both hands are required to cooperate to rotate the bottle cap to open it each time. Conversely, both hands are required to cooperate to rotate the bottle cap in the reverse direction to close it. That is, it is impossible to open and close the bottle cap with one hand. This bottle body and bottle cap structure is extremely inconvenient to use when only one hand is available. For example, when answering a call with one hand, the other hand cannot unscrew the bottle cap. Most people apply makeup before going out in the morning. During the process of answering a call, makeup cannot be applied, and it is impossible to open and close quickly, which affects the makeup progress and the time to go out. Therefore, the existing threaded cosmetic bottle is inconvenient to use. Content of the Utility Model
[0003] Aiming at the defects in the prior art, the connection structure of the bottle cap and the bottle body is optimized to realize opening and closing the bottle cap with one hand, making it more convenient to use. The utility model provides a cosmetic bottle that can be quickly opened and closed; it includes a bottle cap and a bottle body with an opening at the upper end; the opening of the bottle body is provided with a bottle mouth extending upward, and the outer surface of the upper end of the bottle mouth is provided with a limiting ring; the bottle cap includes a cap body and a rod body installed in the cap body. The lower end of the rod body is provided with a limiting claw, the lower end of the limiting claw bends towards the outer side of the rod body and the limiting claw can be elastically deformed; the inner surface of the limiting claw is provided with a limiting protrusion, the upper part of the limiting ring is provided with a chamfer corresponding to the limiting protrusion and the lower part of the limiting ring is provided with a step corresponding to the limiting protrusion; the center of the lower end of the rod body is provided with a sealing body extending downward, and the sealing body is adapted to the bottle mouth of the bottle mouth. The bottle mouth of the bottle body is inserted into the bottle cap, and the sealing body is inserted into the bottle mouth and the limiting protrusion slides over the chamfer of the limiting ring and is stuck under the step of the limiting ring, so that the sealing body seals the bottle mouth.
[0004] The beneficial effect of this device is reflected in that the bottle cap and the bottle body adopt a pull-press opening and closing method, which can realize opening the bottle cap with one hand and closing the bottle cap with one hand. Compared with the existing threaded connection method, the operation is simpler and more convenient, and the influence on the makeup progress is very small.
[0005] Preferably, the lower end of the nozzle is fixedly and sealingly connected to the side wall of the bottle body. The mouth of the nozzle and the sealing body are extrusion-sealed by an annular seal. The upper edge of the seal extends to the upper end of the nozzle, and the middle part of the seal is located in the mouth hole of the nozzle; the mouth hole is provided with an annular groove, and the seal is provided with an annular protrusion corresponding to the annular groove. By clamping the annular protrusion at the annular groove, the seal is fixed at the mouth of the bottle. After the bottle cap is closed on the nozzle, the sealing body presses the seal tightly at the mouth of the bottle. The seal itself is made of rubber or silica gel and can seal the mouth of the bottle after being extruded. The seal is restricted by the annular protrusion and the annular groove, as well as the upper edge of the seal and the mouth of the bottle, so that the seal does not misalign with the nozzle due to the opening and closing of the bottle cap.
[0006] Preferably, a dipping rod extending into the interior of the bottle body is provided at the lower end of the sealing body. The lower edge of the seal bends towards the direction where the dipping rod is located and the lower edge of the seal contacts and seals the side wall of the dipping rod. The lower edge of the seal and the dipping rod form a first seal, which can prevent most lip gloss, mascara, etc. from entering the space between the sealing body and the dipping rod.
[0007] Preferably, there are multiple limiting claws, and all the limiting claws are evenly distributed along the circumferential direction of the rod body. The structures of all the limiting claws are the same. All the limiting claws are unfolded and retracted simultaneously, which plays a key role in the opening and closing of the bottle cap.
[0008] Preferably, the middle part of the rod body is hollow. There are two elastic clips facing outwards on the side wall of the middle part of the rod body, and there are two transverse ridges on the outer surface of the side wall of the middle part of the rod body. The two ridges and the two elastic clips are staggered along the circumferential direction; a convex platform is provided on the outer surface of each elastic clip, and the convex platforms are all lower than the ridges; an annular limiting strip lower than the convex platform is provided on the inner surface of the cover body. By moving the cover body upwards and the convex platform sliding over the annular limiting strip and being stuck below the ridge, the maximum distance of the cover body moving upwards relative to the rod body is restricted. When the bottle cap is in the closed state, the convex platform of each elastic clip is stuck above the annular limiting strip to prevent the bottle cap from being accidentally opened. On the contrary, when the bottle cap is in the open state, each elastic clip slides over the annular limiting strip and returns to its original state under the elastic force to prepare for the next closing.
[0009] Preferably, a longitudinal chute is provided on the side wall of the upper part of the rod body, and a longitudinal limiting strip corresponding to the longitudinal chute is provided on the inner surface of the cover body. By the longitudinal limiting strip sliding relative to the longitudinal chute, the relative rotation between the rod body and the cover body is restricted.
[0010] Preferably, an annular groove corresponding to the limiting claw is provided on the inner surface of the cover body, and the annular groove communicates with the lower edge of the cover body; a chamfer is provided on the upper edge of the annular groove. By moving the cover body upward relative to the rod body, the limiting claw retreats into the annular groove, and the pressure between the limiting protrusion of the limiting claw and the step of the limiting ring decreases. Since the outer surface of the limiting claw is in contact with the inner surface of the cover body, the limiting claw is squeezed by the side wall of the cover body to make the limiting claw close up, and the limiting protrusion of the limiting claw is stuck under the step. When the annular groove of the cover body moves to the position of the limiting claw, the limiting claw is no longer squeezed by the side wall of the cover body, and under the action of the elastic force of the limiting claw, it expands outward into the annular groove. At this time, the limiting claw only contacts the step, and the limiting claw no longer presses tightly under the step and is no longer locked.
[0011] Preferably, the rod body is integrally formed with two elastic clips. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode
[0022] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the attached drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.
[0023] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the art to which the present utility model belongs.
[0024] As Figures 1 to 3 shown, this embodiment provides a makeup bottle that can be quickly opened and closed; it includes a bottle cap 1 and a bottle body 2 with an opening at the upper end. The opening of the bottle body 2 is provided with a bottle mouth 3 extending upward. Due to manufacturing process limitations, the bottle body 2 cannot be integrally formed with the bottle mouth 3, and the lower end of the bottle mouth 3 is hermetically and fixedly connected to the side wall of the bottle body 2. The specific connection structure between the bottle mouth 3 and the bottle cap 1 is as follows:
[0025] As Figures 4 to 6As shown in the figure, a limit ring 4 is provided on the outer surface of the upper end of the bottle mouth 3, and the bottle cap 1 includes a cap body 5 and a rod body 6 installed inside the cap body 5. A limit claw 7 is provided at the lower end of the rod body 6. The lower end of the limit claw 7 bends towards the outside of the rod body 6 and the limit claw 7 can be elastically deformed. A limit protrusion 8 is provided on the inner surface of the limit claw 7. A chamfer 9 corresponding to the limit protrusion 8 is provided on the upper part of the limit ring 4 and a step 10 corresponding to the limit protrusion 8 is provided on the lower part of the limit ring 4. Specifically, a plurality of limit claws 7 are provided, and the specific number of the limit claws 7 is not limited and is determined according to the actual situation. All the limit claws 7 are evenly distributed along the circumferential direction of the rod body 6. All the limit claws 7 have the same structure. All the limit claws 7 unfold and fold simultaneously, which plays a key role in the opening and closing of the bottle cap 1. Specifically, an annular groove 11 corresponding to the limit claw 7 is provided on the inner surface of the cap body 5, and the annular groove 11 communicates with the lower edge of the cap body 5; a chamfer 9 is provided on the upper edge of the annular groove 11. By moving the cap body 5 upward relative to the rod body 6, the limit claw 7 is retracted into the annular groove 11. Since the outer surface of the limit claw 7 is in contact with the inner surface of the cap body 5, the limit claw 7 is squeezed by the side wall of the cap body 5 to make the limit claw 7 fold and the limit protrusion 8 of the limit claw 7 is stuck under the step 10. When the annular groove 11 of the cap body 5 moves to the position of the limit claw 7, the limit claw 7 is no longer squeezed by the side wall of the cap body 5, and under the elastic force of the limit claw 7, it unfolds outward into the annular groove 11, so that the limit protrusion 8 of the limit claw 7 only contacts the step 10 and is no longer locked. In addition, the chamfer 9 is provided on the upper edge of the annular groove 11 so that when the cap body 5 moves downward relative to the rod body 6, the limit claw 7 can abut against the side wall of the cap body 5 along the chamfer 9 with less resistance. Similarly, the chamfer 9 of the limit ring 4 is for the limit claw 7 to slide over more easily.
[0026] As Figures 6 to 8As shown in the figure, in order to achieve the seal between the bottle cap 1 and the bottle body 2, a sealing body 12 extending downward is provided at the center of the lower end of the rod body 6 in this embodiment. The shape of the sealing body 12 is a cone, and the minimum diameter of the sealing body 12 is smaller than the inner diameter of the bottle mouth. The sealing body 12 is adapted to the bottle mouth of the bottle nozzle 3. The bottle nozzle 3 of the bottle body 2 is inserted into the bottle cap 1, and the sealing body 12 is inserted into the bottle mouth, and the limit protrusion 8 slides over the chamfer 9 of the limit ring 4 and is stuck under the step 10 of the limit ring 4, so that the sealing body 12 seals the bottle mouth. Specifically, the bottle mouth of the bottle nozzle 3 and the sealing body 12 are squeezed and sealed through an annular sealing member 13. The upper edge of the sealing member 13 extends to the upper end of the bottle nozzle 3, and the middle part of the sealing member 13 is located in the bottle mouth hole of the bottle nozzle 3; an annular groove 14 is provided in the bottle mouth hole, and the sealing member 13 is provided with an annular protrusion 15 corresponding to the annular groove 14. By engaging the annular protrusion 15 in the annular groove 14, the sealing member 13 is fixed at the bottle mouth. After the bottle cap 1 is closed on the bottle nozzle 3, the sealing body 12 presses the sealing member 13 against the bottle mouth. The sealing member 13 is made of rubber or silica gel, and can seal the bottle mouth after being squeezed. The sealing member 13 is restricted by the annular protrusion 15 and the annular groove 14, and the upper edge of the sealing member 13 and the bottle mouth, so that the sealing member 13 is not misaligned with the bottle nozzle 3 due to the opening and closing of the bottle cap 1. In addition, a dipping rod 16 extending into the bottle body 2 is provided at the lower end of the sealing body 12, and the lower edge of the sealing member 13 bends in the direction of the dipping rod 16 and the lower edge of the sealing member 13 contacts the side wall of the dipping rod 16 for sealing. The lower edge of the sealing member 13 and the dipping rod 16 form a first seal, which can prevent most lip gloss, mascara, etc. from entering the space between the sealing body 12 and the dipping rod 16. And the sealing member 13 forms a second seal, and the second seal is tight, and lip gloss, mascara, etc. cannot overflow.
[0027] As Figure 3 , Figures 6 to 8As shown in the figure, to ensure that the limiting protrusion 8 of the limiting claw 7 can be tightly clamped under the step 10, the middle part of the rod body 6 in this embodiment is hollow. There are two elastic clips 17 facing outward on the side wall of the middle part of the rod body 6, and there are two transverse ridges 18 on the outer surface of the side wall of the middle part of the rod body 6. The two ridges 18 and the two elastic clips 17 are distributed alternately along the circumferential direction. In fact, the elastic clip 17 is formed by opening a concave-shaped notch on the side wall of the middle part of the rod body 6, and the rod body 6 and the two elastic clips 17 are integrated. The material of the rod body 6 is plastic, so that the formed elastic clip 17 itself has a certain elasticity. There is a convex platform 19 on the outer surface of each elastic clip 17, and the convex platform 19 is lower than the ridge 18; there is an annular limiting strip 20 lower than the convex platform 19 on the inner surface of the cover body 5. By moving the cover body 5 upward and the convex platform 19 sliding over the annular limiting strip 20 and then being clamped under the ridge 18, the maximum distance of the cover body 5 moving upward relative to the rod body 6 is restricted. When the bottle cap 1 is in the closed state, the convex platform 19 of each elastic clip 17 is clamped above the annular limiting strip 20 to prevent the bottle cap 1 from being accidentally opened. On the contrary, when the bottle cap 1 is in the open state, each elastic clip 17 slides over the annular limiting strip 20 and then returns to its original state under the elastic force to prepare for the next closing. Further, there is a longitudinal sliding groove 21 on the side wall of the upper part of the rod body 6, and there is a longitudinal limiting strip 22 corresponding to the longitudinal sliding groove 21 on the inner surface of the cover body 5. By the longitudinal limiting strip 22 sliding relative to the longitudinal sliding groove 21, the relative rotation of the rod body 6 and the cover body 5 is restricted.
[0028] In this embodiment, the process of separating the bottle cap 1 and the bottle body 2 with one hand is as follows:
[0029] Grip the bottle body 2 with the palm of the hand, pinch the bottle cap 1 with the thumb and index finger and slide the cover body 5 upward. The cover body 5 and the rod body 6 have a relative displacement. The annular groove 14 moves to the position of the limiting claw 7, and all the limiting claws 7 expand around and all the limiting claws 7 only contact the step 10 of the limiting ring 4. At the same time, the annular limiting strip 20 of the cover body 5 slides upward over the convex platform 19 of the elastic clip 17 and is clamped under the ridge 18, and the cover body 5 can no longer have a relative displacement with the rod body 6.
[0030] Pinch the bottle cap 1 with the thumb and index finger and continue to slide the cover body 5 upward. The cover body 5 drives the rod body 6 to move upward. During this moving process, the limiting protrusion 8 of all the limiting claws 7 slides upward over the limiting ring 4, and the rod body 6 is completely separated from the bottle mouth 3. At this time, the bottle cap 1 and the bottle body 2 can be easily separated. Compared with the existing rotary splitting method, the dipping rod 16 can be pulled out with one hand, and the operation is more convenient.
[0031] In this embodiment, the process of closing the bottle cap 1 and the bottle body 2 with one hand is as follows:
[0032] The palm holds the bottle body 2, and the thumb presses down the cover body 5. The cover body 5 and the rod body 6 move downward synchronously. During this process, the limiting protrusion 8 of the limiting claw 7 slides downward past the limiting ring 4 and the limiting protrusion 8 gets stuck under the boss 19 of the limiting ring 4.
[0033] Continue to press down the cover body 5. The cover body 5 moves downward relative to the rod body 6. The side wall of the cover body 5 presses the limiting claw 7 so that the limiting protrusion 8 of the limiting claw 7 is more tightly stuck under the boss 19 of the limiting ring 4. At the same time, the annular limiting strip 20 of the cover body 5 slides downward past the boss 19 of the elastic clip 17 and gets stuck under the boss 19. At this time, the lower end of the cover body 5 contacts the upper end of the bottle body, and the cover body 5 cannot move downward any further. And the sealing body 12 presses the sealing member 13 against the bottle mouth to achieve the sealing of the bottle mouth 3.
[0034] The bottle cap 1 and the bottle body 2 of this embodiment adopt a pull-press opening and closing method, which can realize opening and closing the bottle cap 1 with one hand. Compared with the existing threaded connection method, the operation is simpler and more convenient, and has little impact on the makeup progress.
[0035] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
