Description

Technical Field

[0001] This utility model relates to the field of cosmetic container technology, and more specifically, to a cosmetic container that reduces emulsion residue. Background Technology

[0002] In daily life, most cosmetics are stored in cosmetic bottles, and the product is dispensed by pressing a button on the bottle. However, the existing structure of cosmetic bottles presents the problem of product residue remaining inside.

[0003] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cosmetic container that reduces emulsion residue.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cosmetic container for reducing lotion residue includes a bottle body with a shoulder sleeve attached to the upper end. A first groove is provided at the center of the shoulder sleeve, and a vacuum pump is installed within the first groove. A second groove, coaxial with the first groove, is formed at the bottom of the first groove. The bottom end of the vacuum pump abuts against the bottom of the second groove, and a through hole corresponding to the vacuum pump inlet is formed at the bottom of the second groove. A piston is longitudinally arranged inside the bottle body, comprising an outer ring and an inner ring located within the outer ring and connected to its inner wall. A third groove, adapted to the second groove, is provided in the middle of the inner ring. The third groove is recessed towards the inner bottom wall of the bottle body, corresponding to the through hole, forming a recessed portion. A small hole is formed at the bottom of the bottle body.

[0007] Furthermore, the inner diameter of the third groove is larger than the outer diameter of the second groove.

[0008] Furthermore, the bottom end of the vacuum pump is provided with an annular protrusion, which is coaxially arranged with the through hole, and the inner diameter of the protrusion is larger than the radius of the through hole.

[0009] Furthermore, the vacuum pump has a first convex ring in the middle, and the groove wall of the first groove has a first slot that matches the first convex ring. The first convex ring is engaged in the first slot. The vacuum pump has a second slot at the bottom, and the groove wall of the second groove has a second convex ring that matches the second slot. The second convex ring is engaged in the second slot.

[0010] Furthermore, the bottom end of the bottle body protrudes towards the piston to form a frustum structure, and the small hole is located on the frustum structure.

[0011] The beneficial effects of this utility model are:

[0012] 1. In this utility model, by setting a third groove, when the emulsion in the bottle decreases to a minimum amount, the emulsion will flow into the third groove, so that the vacuum pump can be inserted into the third groove through the second groove to suck up the small amount of emulsion; when the emulsion decreases further, the remaining emulsion will flow into the recessed part, so that the vacuum pump can suck up the remaining emulsion; by using the cooperation of the third groove and the recessed part, the residue of emulsion in the bottle is reduced.

[0013] 2. In this utility model, by setting an annular protrusion, on the one hand, the lower surface of the protrusion abuts against the bottom of the second groove to restrict the emulsion, preventing the emulsion from flowing into the gap between the inner wall of the second groove and the outer surface of the vacuum pump under the pumping action of the vacuum pump, thus avoiding waste; on the other hand, the protrusion raises the vacuum pump inlet, and the inner diameter of the protrusion is larger than the radius of the through hole, so that the flow rate of the emulsion when flowing through the through hole increases, thereby facilitating the vacuum pump to pick up the emulsion.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: A cosmetic container that reduces lotion residue, such as Figures 1-7 As shown, the device includes a bottle body 1, which is made of plastic and has a cylindrical structure with an open top. A shoulder sleeve 2 for mounting a vacuum pump 3 is installed at the top of the bottle body 1. The vacuum pump 3 is mounted on the shoulder sleeve 2, and a nozzle 5 is mounted on the upper part of the vacuum pump 3. A bottle cap 6 is fitted over the nozzle 5 and snaps onto the shoulder sleeve 2. In use, the bottle cap 6 is removed, and pressing the nozzle 5 activates the vacuum pump 3, pumping the emulsion inside the bottle body 1 to the nozzle 5, where it is extruded through the discharge port.

[0024] Furthermore, such as Figure 3 and Figure 5 As shown, a first groove 201 is provided at the center of the shoulder sleeve 2. A second groove 202, coaxial with the first groove 201, is provided at the bottom of the first groove 201. When the vacuum pump 3 is installed in the first groove 201, the middle part of the vacuum pump 3 is engaged with the first groove 201, and the bottom of the vacuum pump 3 is inserted into the second groove 202 and engaged with the second groove 202. At the same time, the bottom end of the vacuum pump 3 abuts against the bottom of the second groove 202. A through hole 203 is provided at the bottom of the second groove 202, which corresponds to the inlet of the vacuum pump 3. The through hole 203 is provided to facilitate the vacuum pump 3 to draw the emulsion from the bottle 1.

[0025] Furthermore, such as Figure 3 As shown, a piston 4 is longitudinally arranged inside the bottle body 1, and a small hole 101 is opened at the bottom of the bottle body 1. By setting the small hole 101, the area enclosed by the lower part of the piston 4 and the bottle body 1 is connected to the outside air, so that the piston 4 can move upward when the emulsion in the bottle body 1 decreases.

[0026] Preferably, the bottom of the bottle body 1 protrudes towards the piston 4 to form a frustum structure, and the small hole 101 is located on the frustum structure. By setting the frustum structure, the position of the small hole 101 is raised, so that the area enclosed by the lower part of the piston 4 and the bottle body 1 is fully connected with the outside air.

[0027] Furthermore, such as Figure 3 and Figure 6As shown, the piston 4 includes an outer ring 401 and an inner ring 402 located inside the outer ring 401 and connected to the inner wall of the outer ring 401. The outer ring 401 is adapted to the inner cavity of the bottle body 1. The middle part of the inner ring 402 is provided with a third groove 403 adapted to the second groove 202. The third groove 403 is coaxially arranged with the second groove 202. The third groove 403 is recessed towards the inner bottom wall of the bottle body 1 corresponding to the position of the through hole 203 to form a recessed portion 404. The cross-sections of the first groove 201, the second groove 202 and the third groove 403 are all annular structures.

[0028] like Figure 7 As shown, when piston 4 moves upward, the outer ring 401 of piston 4 abuts against the inner wall of bottle 1, scraping the emulsion adhering to the inner wall of bottle 1 to the inner ring 402. By providing a third groove 403, when the emulsion in bottle 1 decreases to a minimum, the emulsion will flow into the third groove 403. The third groove 403 serves to hold a small amount of emulsion, so that the vacuum pump 3 can be inserted into the third groove 403 through the second groove 202 to suck up the small amount of emulsion. When the emulsion decreases further, the remaining emulsion will flow into the recessed portion 404. The recessed portion 404 serves to hold the remaining emulsion, so that the vacuum pump 3 can suck up the remaining emulsion. By utilizing the combined effect of the third groove 403 and the recessed portion 404, the amount of emulsion residue in bottle 1 can be reduced.

[0029] Furthermore, such as Figure 3 and Figure 7 As shown, the inner diameter of the third groove 403 is larger than the outer diameter of the second groove 202. This structural design creates a channel for emulsion flow between the inner wall of the third groove 403 and the outer wall of the second groove 202, allowing the emulsion to flow into this channel and thus facilitating suction by the vacuum pump 3.

[0030] Furthermore, such as Figure 3 , Figure 4 and Figure 7 As shown, the bottom of the vacuum pump 3 is provided with an annular protrusion 301. The protrusion 301 is located on the outer periphery of the inlet of the vacuum pump 3 and is coaxially arranged with the through hole 203. When the vacuum pump 3 is installed in the first groove 201, the protrusion 301 abuts against the bottom of the second groove 202. The inner diameter of the protrusion 301 is larger than the radius of the through hole 203. By setting the protrusion 301, on the one hand, the lower surface of the protrusion 301 abuts against the bottom of the second groove 202 to restrict the emulsion and prevent the emulsion from flowing into the gap between the inner wall of the second groove 202 and the outer surface of the vacuum pump 3 under the pumping action of the vacuum pump 3, thus avoiding waste; on the other hand, the protrusion 301 raises the inlet of the vacuum pump 3, and the inner diameter of the protrusion 301 is larger than the radius of the through hole 203, so that the flow rate of the emulsion when flowing through the through hole 203 increases, thereby facilitating the vacuum pump 3 to pick up the emulsion.

[0031] Furthermore, such as Figure 3 , Figure 4 and Figure 5 As shown, the vacuum pump 3 has a first convex ring 302 in the middle. The groove wall of the first groove 201 has a first slot 204 that matches the first convex ring 302. The first convex ring 302 is engaged with the first slot 204, that is, the vacuum pump 3 is installed in the first groove 201 through the engaging fit between the first convex ring 302 and the first slot 204. The bottom of the vacuum pump 3 has a second slot 303. The groove wall of the second groove 202 has a first slot 304 that matches the second slot 303. The second convex ring 205 is engaged with the second slot 303, meaning the vacuum pump 3 is installed in the second groove 202 through the engagement of the second convex ring 205 and the second slot 303. Through the engagement of the first convex ring 302 and the first slot 204, and the engagement of the second convex ring 205 and the second slot 303, the vacuum pump 3 is securely installed on the shoulder sleeve 2, improving the connection strength between the vacuum pump 3 and the first groove 201 and preventing the vacuum pump 3 from detaching from the first groove 201.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
