Description

Technical Field

[0001] This utility model relates to the technical field of cosmetic packaging containers, and in particular to the technical field of circular rotating pop-out press-type cosmetic dispensing bottles. Background Technology

[0002] Currently, most pump-type cosmetic packaging bottles on the market have their pump heads fixed and exposed. During transportation or storage in bags, these pump heads are easily accidentally pressed due to collisions or pressure, leading to leakage. While some structures exist that use rotation to achieve lifting, these are often complex, the lifting process is often choppy and unsmooth, or they cannot achieve coordinated differential movement between the pump head and the bottle cap. Therefore, the market urgently needs an innovative design that is ingeniously structured, operates smoothly, and effectively protects the pump head. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a circular rotating pop-up press-type cosmetic dispensing bottle. Through rotational operation and the use of a differential lifting mechanism, the press head can be smoothly popped out or hidden, effectively preventing misoperation.

[0004] To achieve the above objectives, this utility model proposes a circular rotary pop-out press-type cosmetic dispensing bottle, comprising an outer shell, an inner liner built into the outer shell, and a pump assembly mounted on the inner liner; the outer shell includes an upper outer shell, a lower outer shell, and an inner liner press-fitted into the lower outer shell, the upper outer circumferential surface of the inner liner fitting with the inner wall of the upper outer shell; the inner wall of the lower outer shell has two driving protrusions distributed circumferentially, and in a 360-degree unfolded plane, the outline of the driving protrusion is formed by connecting a rectangular portion and a right-angled trapezoidal portion; the bottom surface outline of the inner liner matches the upper surface outline of the driving protrusion, and its bottom surface has a square slot for guiding and engaging with the rectangular portion of the driving protrusion; the driving protrusion and the inner liner... The bottom surfaces of the inner liner together form two first guide grooves; the upper outer periphery of the inner liner has two second guide grooves symmetrically arranged, and the lower part of the inner wall of the upper outer shell has symmetrically arranged outer shell sliding protrusions that cooperate with the second guide grooves; the lower outer periphery of the inner liner has two inner liner sliding protrusions that slide and cooperate with the first guide grooves; the pump assembly includes an inner liner cover fixed to the top of the inner liner, the inner liner cover has a vertical slot, and the upper part of the inner wall of the upper outer shell has a vertical protrusion that slides and cooperates with the vertical slot; wherein, the inclination angle of the inclined section of the first guide groove relative to the central axis of the discharge bottle is greater than the inclination angle of the inclined section of the second guide groove relative to the central axis of the discharge bottle.

[0005] Preferably, the profile of the first guide groove consists of a long inclined section in the middle and short straight sections at both ends. This structure efficiently converts rotational motion into linear motion, and the short straight sections at both ends provide stable upper and lower stop points.

[0006] Preferably, the second guide groove has a stepped groove in the middle leading to the top surface of the inner shell. The stepped groove design facilitates the easy insertion of the outer shell sliding protrusion on the inner wall of the upper outer shell into the groove during assembly.

[0007] Preferably, the inner wall of the lower outer shell has an annular groove above the driving protrusion, and the outer circumferential surface of the inner shell liner has an annular protrusion that engages with the annular groove. The engagement of the annular groove and the annular protrusion ensures reliable fixation between the inner shell liner and the lower outer shell.

[0008] Preferably, a guide ramp is provided below the annular protrusion. The guide ramp makes it easier for the inner liner to be pressed into the lower outer shell.

[0009] Preferably, the inner liner includes an inner liner body, a scraper disposed in the inner cavity at the bottom of the inner liner body, and an inner liner bottom cap pressed onto the bottom of the inner liner body.

[0010] Preferably, the upper inner wall of the upper outer shell is further provided with a discharge port for accommodating the pressing head and a raised clearance groove on the inner liner cover. The clearance groove provides the necessary space for the moving parts and avoids structural interference during lifting and lowering.

[0011] The beneficial effects of this utility model are as follows: By integrating two guide grooves (the first guide groove and the second guide groove) with different inclination angles between the outer shell and the inner liner, this utility model creatively achieves differential lifting motion driven by rotation. This structure allows the inner liner to move faster through the sliding protrusion in the first guide groove than the upper outer shell to move faster through the sliding protrusion in the second guide groove. This ultimately achieves a usable state where the press head is fully extended and the inner liner cap is flush with the bottle opening, and a retracted state where the press head is completely hidden. The entire mechanism is compact, reliable in operation, and smooth in feel, greatly improving the product's ease of use, safety, and overall appearance.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

Detailed Implementation

[0015] See Figures 1 to 9 This utility model relates to a circular rotary pop-out press-type cosmetic dispensing bottle, comprising an outer shell 1, an inner liner 2 built into the outer shell 1, and a pump assembly 3 installed on the inner liner 2. The outer shell 1 includes an upper outer shell 11, a lower outer shell 12, and an inner liner 13 pressed into the lower outer shell 12. The upper outer circumferential surface of the inner liner 13 mates with the inner wall of the upper outer shell 11.

[0016] like Figure 6 As shown, the inner wall of the lower outer shell 12 has two driving protrusions 121 distributed in the circumferential direction. In the 360-degree unfolded plane, the outline of the driving protrusion 121 is formed by connecting a rectangular part and a right-angled trapezoidal part.

[0017] Combination Figure 8 and Figure 9As can be seen, the bottom contour of the inner shell liner 13 matches the upper surface contour of the drive protrusion 121, and its bottom surface has a square slot 131 for guiding and engaging with the rectangular portion of the drive protrusion 121. After assembly, the drive protrusion 121 and the bottom surface of the inner shell liner 13 together form two first guide grooves 4. The inner wall of the lower outer shell 12 has an annular groove 122 above the drive protrusion 121, and the outer peripheral surface of the middle part of the inner shell liner 13 has an annular protrusion 133 that engages with the annular groove 122. A guide slope 134 is provided below the annular protrusion 133.

[0018] like Figure 9 As shown, the upper outer periphery of the inner shell liner 13 is symmetrically provided with two second guide grooves 132, and the middle part of the second guide groove 132 is provided with a stepped groove 1321 leading to the top surface of the inner shell liner 13.

[0019] like Figure 4 As shown, the lower part of the inner wall of the upper outer shell 11 is symmetrically provided with outer shell sliding protrusions 111 that cooperate with the second guide groove 132.

[0020] like Figure 1 and Figure 7 As shown, the inner liner 2 includes an inner liner body 22, a scraper 23 disposed in the inner cavity at the bottom of the inner liner body 22, and an inner liner bottom cap 24 pressed into the bottom of the inner liner body 22. Two inner liner sliding protrusions 21 are symmetrically arranged on the lower outer circumference of the inner liner 2, which slide in cooperation with the first guide groove 4. The pump assembly 3 includes a pump body, a pressing head 32, and an inner liner cap 31. The inner liner cap 31 is fixed to the top of the inner liner body 22, and the pump body is mounted on the inner liner cap 31, with its lower end extending into the inner liner 2 and its upper end connected to the pressing head 32.

[0021] like Figure 5 and Figure 7 As shown, the inner liner cover 31 has a vertical slot 311, and the upper part of the inner wall of the upper outer shell 11 has a vertical protrusion 112 that slides with the vertical slot 311. The upper part of the inner wall of the upper outer shell 11 also has a discharge port for accommodating the pressing head 32 and a relief groove 113 for the protrusion on the inner liner cover 31.

[0022] The core of this utility model is that the tilt angle of the inclined section of the first guide chute 4 relative to the central axis of the discharge bottle is greater than the tilt angle of the inclined section of the second guide chute 132 relative to the central axis of the discharge bottle.

[0023] The working process of this utility model: In operation, the circular rotary pop-up press-type cosmetic dispensing bottle of this utility model achieves lifting and lowering through the cooperation of the inner liner sliding protrusion and the first guide groove when the lower outer shell is rotated. At the same time, the upper outer shell also achieves lifting and lowering through the cooperation of the outer shell sliding protrusion and the second guide groove. Because the inclination angle of the first guide groove is greater, the lifting and lowering speed of the inner liner is greater than that of the upper outer shell, thereby realizing the pop-up and retraction of the press head, and ensuring that the top surface of the inner liner cap is flush with the top surface of the upper outer shell when in the pop-up state.

[0024] Example: In one embodiment, the angle between the inclined section of the first guide groove 4 and the horizontal direction is 45 degrees, while the angle between the inclined section of the second guide groove 132 and the horizontal direction is 20 degrees.

[0025] Advantages: This design produces a significant lift difference, allowing the press head 32 to achieve sufficient pop-up height within a limited rotation angle, while the upper housing lifts to a moderate height, ensuring structural stability.

[0026] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
