Abstract
Description
Technical Field
[0001] The utility model relates to the field of cosmetic packaging devices, in particular to a pressing and popping lipstick tube. Background Art
[0002] Existing lipstick tubes generally consist of an outer tube, a middle core and a base. The middle core is snap-fitted inside the outer tube, and the lipstick or lip balm stored in the middle core is pushed out for use or retracted to its original position by rotating the base. Due to the above characteristics, the end of the middle tube is generally hidden inside the orifice of the outer tube during the design of traditional lipstick tubes. Although this avoids external contamination of cosmetics during actual use, the rotation stroke during use increases. Since the rotation action is relatively complex and involves more components, on the one hand, the production cost is relatively high, and on the other hand, in actual application, sometimes the action of pushing and retracting will be stuck due to the defects of individual parts, and a greater force is required to complete the entire action.

[0018] The following will elaborate on the preferred embodiments of the present utility model in conjunction with the drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model.
[0019] Please refer to Figure 1 and Figure 2 , the embodiments of the present utility model include:
[0020] A pressing and popping lipstick tube, characterized in that the pressing and popping lipstick tube comprises an outer tube 1, a base 3, a middle beam core 2, a movable member 4 and a spring 5. The movable member 4 is sleeved inside the outer tube 1. A slider is provided on the movable member 4. A corresponding limit chute is provided on the inner side wall of the outer tube 1, so that the movable member slides relative to the outer tube 1 within the range determined by the limit chute. A receiving cavity is provided at the front end of the movable member 4, and the middle beam core 2 is embedded in the receiving cavity. A guiding column 201 is provided at the rear end of the movable structure. A spring pressing platform 202 is provided on the column body of the guiding column 201. The base 3 is installed at the bottom of the outer tube 1. A spring installation groove is provided at the central position of the base 3. The bottom of the spring 5 is fixed in the spring installation groove. The rear end of the guiding column 201 is inserted into the top of the spring 5. A limiting elastic plate 303 is further provided on one side of the spring 5. A clamping block 304 is provided at the upper part inside the limiting elastic plate 303. The clamping block 304 is clamped on the front end face of the spring pressing platform 202. An inclined surface inclined outward is provided at the top of the limiting elastic plate 303. A limiting block 101 is provided at the position corresponding to the top end of the limiting elastic plate 303 inside the tube body of the outer tube 1. The limiting block 101 is provided with an inclined surface structure matching the inclined surface at the top of the limiting elastic plate 303. Thus, in the non-working state, the rear end face of the spring pressing platform 202 presses tightly against the top end of the spring 5, the limiting block 101 is closely attached to the top of the limiting elastic plate 303, and the clamping block 304 clamps the front end face of the spring pressing platform 202. In the pressing state, the limiting block 101 pushes the limiting elastic plate 303 to bend outward along the inclined surface, so that the clamping block 304 is separated from the upper end face of the spring pressing platform 202. The spring 5 automatically returns, pushes the movable member 4 to move forward, and pushes the middle beam core 2 to pop out forward. The ejection stroke is restricted by the structural cooperation between the outer tube nozzle and the middle beam core.
[0021] It is convenient for the user to take and place the cosmetics placed in the middle beam core 2. When the use is completed, gently push down the middle beam core 2, and while compressing the spring 5, the clamping block 304 on the limiting elastic plate 303 can be made to re-clamp the spring pressing platform 202.
[0022] The inclination angle of the inclined surface is 30 to 60°. Generally, the angle adopted in actual production is 45°. The reason for adopting the above range is that on the one hand, it is necessary to ensure that the deformation amount of the limiting elastic plate 303 during pushing is large enough to enable the clamping block 304 to be separated from the spring pressing platform 202, and on the other hand, the pressing force cannot be too large to facilitate use.
[0023] The spring pressing platform 202 has a flat front end face and a spherical rear end face. The reason for adopting this structure is that the flat front end face facilitates lapping and fixing the position with the clamping block 304. The spherical rear end face can be aligned when contacting the front end of the spring 5, and will not slide when being pressed. On the other hand, when resetting, the arc-shaped contour facilitates pushing the clamping block 304, causing the limiting elastic plate 303 to bend outward, so that the clamping block 304 can rebound and catch the spring pressing platform 202 smoothly after reaching the front end face position.
[0024] The side wall of the base 3 is provided with a hollowed-out orientation hole 302, and a corresponding orientation block 102 is provided at the corresponding position inside the outer tube 1. The combination of the orientation hole 302 and the orientation block 102 can control the stroke of the base 3 when being pressed. On the one hand, it prevents the pressing amplitude from being too large, and on the other hand, it will not fall out of the outer tube 1 when resetting after the pressing is completed.
[0025] A relief notch is provided at the position of the side wall of the base 3 behind the limiting elastic plate 303. The purpose of setting the relief notch is to increase the movement space when the limiting elastic plate 303 deforms, improve the overall structural compactness, and prevent the back of the limiting elastic plate 303 from being blocked by the side wall after pressing, so that the detachment action cannot be completed.
[0026] When the utility model is actually used, the ejection action of the beam core 2 in the application element can be completed by a simple pressing action of the base 3, and when it is reversely pressed into the outer tube 1, the reset action can be completed. The whole process is light and simple, requires little external force, and does not require a rotating action, which is more convenient and fast. The internal connection control structure is also simple and reliable, and is not prone to failures during use.
[0027] The above are only the embodiments of the utility model, and do not limit the patent scope of the utility model accordingly. All equivalent structural or equivalent process transformations made by using the description and drawings of the utility model, or directly or indirectly applied in other related technical fields, are equally included in the patent protection scope of the utility model.
