Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic containers, in particular to a bottle mouth structure with a short pump installed. Background Art

[0002] There are many types of cosmetic containers to meet the characteristics and usage requirements of different cosmetics. Common container forms include bottles, powder compacts, boxes, droppers, small bags, jars, pumps, palettes, tubes and sprays. For example, some liquid and paste cosmetics, such as lotions and emulsions, usually use bottles as containers, while powdered cosmetics, such as eye shadows and blush, often use powder compacts or palettes. In addition, some cosmetics that require precise control of dosage, such as essences, usually use droppers or pumps as containers.

[0003] Common pump bottles and pump tube containers usually have an outward-convex opening at the top of the container, with threads around the opening, and the pump head is provided with internal threads and connected to the opening with an outer sleeve, that is, the pump head is arranged at the top of the bottle mouth. For example, a cosmetic container disclosed in the patent document with the announcement number CN210417579U adopts this classic design. However, this outward-convex opening will cause the pipeline under the pump head to be too long and increase the overall height of the container. At the same time, the volume of the container that can effectively store liquids and pastes is relatively small.

[0004] Therefore, it is urgent to provide a bottle mouth structure for installing a short pump to solve the above technical problems. Summary of the invention

[0005] In view of the problems in the related art, the utility model proposes a bottle mouth structure for installing a short pump, which is highly optimized for containers of the pump bottle type.

[0006] The utility model is achieved in this way:

[0007] A bottle mouth structure for installing a short pump is arranged at the upper end of a bottle body, comprising a bottle mouth and a pump head, wherein the bottle mouth and the pump head are cooperatively connected; the bottle mouth comprises an annular platform portion protruding upward at the upper end of the bottle body, wherein the annular platform portion extends downward toward the inside of the bottle body and sinks to form a sinking platform portion, wherein a first opening is arranged at the center of the sinking platform portion; a cavity is formed between the sinking platform portion and the annular platform portion;

[0008] During installation, part of the pump head is disposed in the cavity and abuts against the upper side surface of the sink portion, while the other part passes through the first opening and enters the interior of the bottle body.

[0009] By providing the sunken platform, the cavity area in the middle of the annular platform can be reasonably utilized, and the pump head can be installed downward in the cavity. Compared with the traditional design, the overall height of the pump bottle is significantly reduced.

[0010] As a further optimization of the above solution, a connection kit is also included, and the connection kit is cooperatively connected with the annular platform to fix the pump head.

[0011] As a further optimization of the above solution, the connection kit includes a crimping portion, which is sleeved on the peripheral side of the pump head and clamped downward with the pump head;

[0012] A sleeve portion is formed by folding outward along the top edge of the connection kit, and the sleeve portion is matched and fixedly connected with the ring portion.

[0014] As a further optimization of the above solution, a limiting convex ring is provided along the circumference of the pump head; the connecting sleeve is provided with a second opening in the center of the crimping portion;

[0015] The pump head passes downward through the first opening at the lower half of the limiting convex ring;

[0016] The pump head passes through the second opening upwardly at the upper half of the limiting convex ring;

[0017] The upper side surface and the lower side surface of the limiting convex ring are respectively in contact with the crimping portion and the sinking portion.

[0018] As a further optimization of the above solution, the cross section of the sleeve portion forms a U-shaped structure, including a first inner side surface and a second inner side surface facing opposite sides, and the first inner side surface is located on the outer peripheral side of the second inner side surface;

[0019] A raised first buckle strip is provided along the first inner side surface, and a raised second buckle strip is provided along the outer side surface of the ring platform portion, and the first buckle strip and the second buckle strip are clamped together; when clamped, the first buckle strip is located below the second buckle strip, so that the connecting kit is fixedly connected to the bottle mouth.

[0020] Furthermore, a limiting convex strip is provided along the second inner side surface, and a limiting groove is provided along the inner side surface of the ring platform portion to cooperate with the limiting convex strip. The setting of the limiting convex strip and the limiting groove further strengthens the fastening connection between the connecting kit and the bottle mouth.

[0021] As a further optimization of the above scheme, the first inner side surface is further provided with a plurality of first convex teeth which are evenly spaced and vertically arranged above the first buckle strip; the outer side surface of the ring platform portion is further provided with a plurality of second convex teeth which are evenly spaced and vertically arranged above the second buckle strip; the first convex teeth and the second convex teeth are staggered.

[0022] When the connecting kit is installed on the bottle mouth, part or all of the first protruding teeth and the second protruding teeth are mutually engaged, thereby increasing the friction resistance of the connecting kit and the bottle mouth at the rotating contact surface and further enhancing the connection stability between the two.

[0023] As a further optimization of the above solution, the connection kit includes a sunken groove, which is located in the center of the sleeve portion; the central opening of the groove is formed as the second opening; and the portion of the groove around the second opening is formed as the crimping portion.

[0024] As a further optimization of the above scheme, a raised wedge portion is provided on the outer peripheral side of the pump head above the limiting convex ring; the wedge portion includes an inclined surface facing obliquely upward; a slot is formed between the wedge portion and the limiting convex ring; the wedge portion passes upward through the second opening, and the crimping portion is embedded in the slot.

[0025] The slot is used to improve the fastening connection between the connection kit and the pump head; the wedge part assists the fitting connection between the connection kit and the pump head. The inclined surface acts as a guide surface, and the inclined surface can also be replaced by a smooth arc surface.

[0026] As a further optimization of the above solution, a press nozzle is connected to the top of the pump head; and an annular gap is formed between the groove and the pump head.

[0027] The annular gap is formed as a stroke space for the press nozzle to be pressed downward.

[0028] As a further optimization of the above solution, an annular sealing ring is further connected between the pump head and the upper side surface of the sinking platform.

[0029] The sealing ring can improve the airtightness of the connection between the pump head and the bottle mouth to prevent leakage of liquid or paste inside the bottle.

[0030] The beneficial effects are as follows:

[0031] The utility model provides a bottle mouth structure for installing a short pump, wherein a cavity formed by sinking is provided at the bottle mouth, and a pump head is installed in the cavity, and the pipeline of the pump head passes downward through the opening at the bottom of the cavity into the interior of the bottle body. Compared with the prior art, this solution makes full use of the inner cavity space at the bottle mouth and significantly reduces the overall height of the pump bottle. For pump bottles of the same capacity, the pump bottle of this solution is shorter; or for pump bottles of the same height, the pump bottle provided by this solution can store more space capacity.
