Description

Technical Field

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

[0002] In recent years, with the improvement of economic level, more and more people have higher demands for their external decoration and appearance. Along with consumers' pursuit of beauty and increasing requirements for cosmetics quality, the corresponding cosmetics market demand has generally maintained an upward trend.

[0003] Cosmetics usually exist in the form of pastes, liquids and powders, and most of them contain a variety of ingredients. Different types of cosmetics have special storage requirements. Some ingredients in cosmetics are extremely easy to oxidize and deteriorate after contact with air. Some cosmetics need to maintain a specific humidity for long-term storage and use. Some cosmetics contain a high proportion of volatile alcohol; once the product deteriorates, there is a greater risk of continuing to use it... Therefore, the design of cosmetic containers has relatively high requirements for airtightness, especially considering that cosmetics are directly applied to human skin and have a very large impact on the health of users. Cosmetic containers must have excellent airtightness to ensure the stability of cosmetic storage.

[0004] Currently, most cosmetic containers on the market use a storage method, usually a packaging tube or a packaging bottle, and the opening of the container is mostly connected by a spiral connection. For example, the patent document with the announcement number CN211870208U provides a press-type cosmetic packaging tube, which uses a spiral connection to connect the packaging tube and the pressing structure. However, due to the characteristics of the spiral connection, as long as the sealing structure such as the bottle cap and the pressing head is opened once and installed again, the airtightness of the container is usually poor, especially when the user does not tighten it. Just like a common cola bottle, after drinking the cola and then covering it, it only takes a few hours for the carbon dioxide in the cola bottle to escape. Correspondingly, this type of cosmetic container has the problem of easy deterioration after use.

[0005] Therefore, there is an urgent need to provide a pump bottle mounting structure with enhanced sealing to solve the above technical problems. Summary of the invention

[0006] In view of the problems in the related art, the utility model proposes a pump bottle installation structure with enhanced sealing, which has a better sealing effect.

[0007] The utility model is achieved in this way:

[0008] A pump bottle mounting structure with enhanced sealing, comprising a bottle body and a pump head, wherein the top of the bottle body is provided with a bottle mouth; the bottle body is provided with a raised first ring platform along the edge of the bottle mouth; the bottle body is further provided with a raised second ring platform on the circumference of the first ring platform, and an annular sealing groove is formed between the first ring platform and the second ring platform;

[0009] A fastener is provided between the bottle body and the pump head; the fastener is fixed to the peripheral side of the pump head and is tightly connected to the pump head; the fastener is also provided with a sealing portion extending downward on the peripheral side of the pump head, and the sealing portion and the sealing groove are adapted to each other;

[0010] During assembly, the pump head portion passes through the bottle mouth and enters the interior of the bottle body, the sealing portion and the sealing groove are tightly connected, and the fastener is detachably fixedly connected to the bottle body.

[0011] Providing a sealing groove on the bottle body and a sealing part on the fastener can effectively extend the shortest distance from the bottle mouth gap to the outside world. Starting from the bottle mouth, the complex path passes through the first ring platform, the winding sealing groove, and then to the second ring platform, constructing an insurmountable barrier. It is difficult for outside air to penetrate into the pump bottle, and it is difficult for liquid and paste in the pump bottle to seep out, which ultimately greatly enhances the sealing of the pump bottle.

[0012] As a further optimization of the above solution, the fastener extends outward from the top edge of the sealing portion and folds downward to form an annular sleeve groove with an opening facing downward, wherein the folded portion is the folded portion; the sleeve groove cooperates with the second ring platform.

[0013] Providing the folded portion can further improve the tightness and sealing of the connection between the fastener and the bottle body.

[0014] As a further optimization of the above solution, the inner side surface of the folding portion is provided with a first convex strip, and the first convex strip is extended in the horizontal direction; the outer peripheral side of the second ring platform is also provided with a second convex strip; during assembly, the first convex strip is buckled under the second convex strip.

[0015] The fastener and the bottle body are fastened together by the first and second convex strips. The first and second convex strips are provided with guide surfaces to increase the smoothness of the fit; the guide surfaces are inclined or curved, or are processed with arcs, inclined surfaces, chamfers, rounded corners, etc.

[0016] As a further optimization of the above scheme, the inner side surface of the folding portion is further provided with a plurality of first convex teeth which are evenly spaced and vertically arranged above the first convex strip; the outer side surface of the second ring platform is further provided with a plurality of second convex teeth which are evenly spaced and vertically arranged above the second convex strip; the first convex teeth and the second convex teeth are staggered and engaged with each other.

[0017] When the fastener is installed on the bottle body, part or all of the first protruding teeth and the second protruding teeth are locked with each other, thereby increasing the friction resistance between the fastener and the bottle body at the rotational contact surface and further enhancing the connection stability between the two.

[0018] As a further optimization of the above solution, a third convex strip is provided on the outer peripheral side of the sealing portion, and the third convex strip is extended in the horizontal direction; a first limiting groove is provided on the inner peripheral side of the second ring platform; the third convex strip and the first limiting groove cooperate with each other.

[0019] The third convex strip and the first limiting groove further improve the fastening connection between the fastener and the bottle body and enhance the sealing performance. The third convex strip is provided with a guiding surface to improve the comfortable experience during the fitting.

[0020] As a further optimization of the above solution, a limiting convex ring is provided along the outer peripheral side of the pump head; during assembly, the lower side surface of the limiting convex ring abuts against the first ring platform, and the upper side surface abuts against the fastener.

[0021] As a further optimization of the above solution, a limiting opening is provided in the center of the fastener, which runs through the upper and lower parts, and a ring-shaped limiting platform is formed along the edge of the limiting opening;

[0022] The outer peripheral side of the pump head is further provided with a fourth convex strip above the limiting convex ring; a second limiting groove is formed between the fourth convex strip and the limiting convex ring;

[0023] During assembly, the pump head passes through the limiting opening upward until the fourth convex strip is embedded above the limiting platform, and at this time, the second limiting groove and the limiting platform cooperate with each other.

[0024] The limiting platform, the second limiting groove and the fourth convex strip are provided to jointly fasten the fastener and the pump head. The guiding surface is provided on the limiting platform and the fourth convex strip to improve the comfortable experience during the matching.

[0025] As a further optimization of the above solution, the top of the pump head is also connected to a pressing head that can move downward;

[0026] The fastener is also provided with an annular groove with an opening facing upward, and the annular groove is located inside the sealing portion; the annular groove cooperates with the bottom edge of the pressing head.

[0027] The annular groove is a reasonable use of the structure of the sealing part, serving as a space for the pressing head to move downward, while reducing the thickness and weight of the fastener and saving materials.

[0028] As a further optimization of the above solution, a limiting ring platform is formed by protruding upward along the outer edge of the annular groove, and the limiting ring platform is located on the peripheral side of the pressing head.

[0029] As a further optimization of the above solution, an annular sealing ring is further provided between the limiting convex ring and the first ring platform.

[0030] The ring seal further strengthens the sealing performance of the pump bottle.

[0031] The beneficial effects are as follows:

[0032] The utility model provides a pump bottle installation structure with enhanced sealing, which effectively extends the shortest distance from the gap of the bottle mouth to the outside world by arranging an annular sealing groove on the peripheral side of the bottle mouth and cooperating with the sealing part on the fastener, and constructs an insurmountable barrier through a complex path starting from the bottle mouth, passing through the first ring platform, the winding sealing groove, and then to the second ring platform in sequence, so that it is difficult for outside air to penetrate into the pump bottle, and it is difficult for liquid and paste in the pump bottle to seep out, thereby greatly enhancing the sealing of the pump bottle.
