Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to a press-and-release type opening cream bottle. Background Technology

[0002] Currently, screw-top sealing structures remain the mainstream in the cosmetic cream and lotion bottle packaging market. This structure achieves opening and closing through the engagement of the cap and the bottle's threads. While it offers stable basic sealing performance, its operation mode has significant limitations and fails to meet modern consumers' upgraded demands for convenience and safety.

[0003] From the perspective of the limitations of screw cap structure, it relies on the engagement of the cap and the bottle body threads one turn at a time. The operation process requires the user to apply force to rotate and maintain concentration. Especially when the bottle opening is small (such as travel size or portable size) or there is cream residue on the surface of the cream bottle (such as cream products), the force applied by hand is prone to slipping, jamming, or even damage to the thread structure due to insufficient friction.

[0004] As for the other type of snap-fit ​​structure, although it simplifies some of the operation steps through mechanical snap-fit, its design still has significant shortcomings. Users need to actively pry the cover to unlock the snap-fit. If the force is uneven or the snap-fit ​​elasticity is not designed properly during the operation, problems such as "difficult to open" or "loose closure" may occur.

[0005] In summary, existing cream jar packaging technology has significant shortcomings in terms of ease of use and fails to meet consumers' demands for innovative and user-friendly designs. Therefore, an improved solution that adapts to modern consumption scenarios is urgently needed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a press-and-release type opening cream bottle, which transforms the traditional screw cap operation into a simple and labor-saving operation of "press to open" and "press to close", effectively balancing opening and closing efficiency and ease of use.

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a press-and-release type opening cream bottle, including a top cap, an inner liner, a top cap fixing ring, an outer shell, an inner support, a spring, and a bottom cap. The outer shell is an axially through hollow structure, and a support column is provided inside the outer shell. The inner support is inserted into the support column, and the inner liner is provided on the inner support. The upper end of the spring abuts against the inner support, and the lower end of the spring abuts against the bottom cap. The spring and the bottom cap are both fixed inside the outer shell. The top cap fixing ring is sleeved on the outside of the support column, and the top cap is inserted into the outer shell and forms a limited sliding fixed connection with the top cap fixing ring.

[0008] Furthermore, the outer circumferential surface of the top cover fixing ring is provided with at least three limiting blocks arranged in a circular array and a guide rail of the same number as the limiting blocks. The inner wall of the top cover is provided with a boss. When the boss slides along the guide rail to below the limiting block, it restricts the top cover from detaching from the outer shell.

[0009] Furthermore, the guide rail specifically includes a first sliding section, a first sliding section, a second sliding section, and a second sliding section. The limiting block is disposed above the first sliding section and the second sliding section. When the top cover is pressed down to close, the protrusion moves sequentially along the first sliding section and the first sliding section until the guide rail is located below the limiting block.

[0010] Furthermore, when the top cover is pressed down to open and rise, the protrusion slides sequentially along the second sliding section and the second sliding section until it disengages from the guide rail to complete the opening action.

[0011] Furthermore, the upper end of the support column is provided with a retaining ring, and the top cover fixing ring is sleeved on the outside of the support column, and the sliding of the top cover fixing ring is restricted by the retaining ring.

[0012] Furthermore, the outer circumferential surface of the top cover fixing ring is provided with 8 to 14 limiting blocks arranged in a circular array.

[0013] Furthermore, the inner support has at least two positioning ribs on its outer circumference, and the support column has the same number of guide grooves. The inner support is inserted into the support column by inserting the positioning ribs into the guide grooves.

[0014] Furthermore, the bottom cover is provided with a first limiting ring, the bottom of the inner support is provided with a second limiting ring, and the spring is placed in the middle area between the first limiting ring and the second limiting ring.

[0015] Furthermore, the bottom cover is provided with a buckle, and the outer shell is provided with a slot, so that the bottom cover and the outer shell are fixed by the buckle engaging with the slot.

[0016] Furthermore, the inner liner is provided with a pull pad and an aluminum foil sealing film, and the top cover is provided with a gasket.

[0017] This utility model provides a press-and-release type of opening cream bottle, which has the following advantages compared with the prior art: Unlike traditional screw-cap cream bottles, this utility model adopts a press-and-release design. When pressing to open the top cap, the top cap moves downward under pressure. After releasing the top cap, the spring generates an upward reaction force, thereby pushing the top cap upward until it detaches from the outer shell, completing the opening. When pressing to close the cap, the top cap moves downward. After stopping the pressing, the spring reaction force drives the top cap to be fixed, thus closing the cap. Only one press is needed to open or close the cream bottle, transforming the traditional screw-cap operation into a simple and labor-saving "press to open" and "press to close" operation, effectively balancing opening and closing efficiency and ease of use.

[0018] Other features and advantages of this invention will become apparent from the following detailed description, or may be learned in part by practice of this invention.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0026] like Figures 1-10As shown, a press-and-release type cream bottle includes a top cap 1, an inner liner 5, a top cap retaining ring 6, an outer shell 7, an inner support 8, a spring 9, and a bottom cap 10. The outer shell 7 is an axially through hollow structure, and a support column 701 is provided inside the outer shell 7. The inner support 8 is inserted into the support column 701 from bottom to top. The upper end of the spring 9 abuts against the inner support 8, and the lower end of the spring 9 abuts against the bottom cap 10. The spring 9 is placed between the inner support 8 and the bottom cap 10 and is fixed together with the bottom cap 10 inside the outer shell 7. The top cap retaining ring 6 is sleeved on the outside of the support column 701. The top cap 1 is inserted into the outer shell 7 and forms a limited sliding fixed connection with the top cap retaining ring (e.g., Figure 9 , Figure 10 The inner liner 5 and the inner support 8 are pressed tightly into the support column 701 of the outer shell 7.

[0027] Furthermore, the top cover fixing ring 6 is freely rotatable, and its outer circumferential surface is provided with at least three circumferentially arrayed limiting blocks 601 (the larger the diameter of the top cover fixing ring, the more limiting blocks are usually required; the optimal number is 8-14, and in this embodiment, it is 10) and a guide rail 602. The limiting blocks 601 are inverted V-shaped, and the inner wall of the top cover 1 is provided with a boss 101. The boss 101 cooperates with the guide rail 602 to achieve a limiting sliding fixed connection. When the top cover 1 is pressed down and raised, the boss 101 will slide along the guide rail 602. When the boss 101 slides below the limiting block 601, the top cover 1 will be restricted from detaching from the outer shell 7.

[0028] Furthermore, the guide rail 602 is multi-segmented, preferably four-segmented, specifically including a first sliding section 6021, a first sliding section 6022, a second sliding section 6023, and a second sliding section 6024. The limiting block 601 is disposed above the first sliding section 6022 and the second sliding section 6023, which restricts the upward movement of the boss 101, thereby fixing the top cover 1 inside the outer shell 7.

[0029] Furthermore, the upper end of the support column 701 is provided with a retaining ring 7011, and the top cover fixing ring 6 is sleeved on the outside of the support column 701, and the retaining ring 7011 restricts the up and down movement of the top cover fixing ring 6.

[0030] Furthermore, the inner support 8 is provided with at least two positioning ribs 801 on its outer periphery, and the support column 701 is provided with a corresponding number of guide grooves 7012. The inner support 8 is placed inside the support column 701 from bottom to top, so that the positioning ribs 801 are inserted into the guide grooves 7012, and the guide grooves 7012 restrict the inner support 8 from coming out from above the support column 701.

[0031] Furthermore, the bottom cover 10 is provided with a first limiting ring 1001, the bottom of the inner support 8 is provided with a second limiting ring 802, and the spring 9 is placed inside the first limiting ring 1001 and the second limiting ring 802.

[0032] Furthermore, the bottom cover 10 is provided with a buckle 1002, and the outer shell 7 is provided with a slot 702, and the bottom cover 10 and the outer shell 7 are snapped together and fixed.

[0033] Furthermore, the inner tray 8 is provided with an inner liner 5 for storing cosmetic creams, and the inner liner 5 is provided with a pull pad 4 for covering the cosmetic creams in the inner liner 5.

[0034] Furthermore, the inner liner 5 is provided with an aluminum foil sealing film 3, and the top cover 1 is provided with a gasket 2, which enhances the sealing of the cosmetic cream in the inner liner 5.

[0035] This utility model provides a press-and-release type of cream bottle with the following advantages compared to existing technologies: Unlike traditional screw-cap cream bottles, this utility model adopts a press-and-release design. When pressing to open, the top cap 1 moves downward under pressure, and the protrusion 101 slides along the second sliding section 6023 of the guide rail 602. After releasing, the spring 9 generates an upward reaction force, pushing the protrusion 101 to slide along the second upward sliding section 6024, and the top cap 1 disengages from the outer shell 7 to complete the opening. When pressing to close, the top cap 1 moves downward, causing the protrusion 101 to slide along the first sliding section 6021. After stopping the pressing, the reaction force of the spring 9 drives the protrusion 101 to slide along the first upward sliding section 6022 to below the limiting block 601, and the top cap 1 is fixed to close. Only one press is needed to open or close the cream bottle, transforming the traditional screw-cap operation into a linear "press to open" and "press to close" action, effectively balancing opening and closing efficiency and ease of use.
