Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a press-injection functional bottle cap. Background Art

[0002] Premixed liquids, such as beverages and oral liquids, are frequently used in the food and health product sectors. However, a major challenge with premixed liquids is their susceptibility to degradation and loss of activity due to external factors, such as light, heat, oxygen, and ultraviolet light. Consequently, preservatives, stabilizers, and other additives are often added. However, even with these additives, the shelf life of premixed liquids remains shorter than that of solids. Furthermore, the flavor of liquid formulations changes over time and due to environmental factors during storage, hindering the development of various food products. For example, anthocyanin-containing, vitamin-containing, and probiotic-containing beverages significantly shorten their activity after mixing with water. With rising living standards, people are increasingly seeking healthier bottled beverages. If a beverage bottle cap could be designed that could store solid ingredients and allow for on-demand dispensing, the nutritional ingredients would be isolated from water before use, preserving the active ingredients and ensuring ready-to-use dispensing. This would allow manufacturers to avoid the use of preservatives and stabilizers, while providing consumers with a reliable product. This design concept has been widely recognized.

[0003] Traditional push-to-fill functional bottle caps have been found to have shortcomings during use. After pressing, the powder inside the cap cannot be quickly injected into the bottle. Vigorous shaking of the bottle is often required to accelerate the powder injection, which is a cumbersome operation. Therefore, there is a need to optimize and improve the traditional push-to-fill functional bottle caps. Utility Model Content

[0004] The purpose of the present invention is to overcome the above-mentioned problems existing in the traditional technology and provide a press-injection functional bottle cap.

[0005] In order to achieve the above technical objectives and the above technical effects, the present invention is implemented through the following technical solutions:

[0006] A push-injection functional bottle cap comprises a lower cover, an upper cover, a pressing tube member and an inner plug member. The upper end of the lower cover is mounted with a detachable upper cover, the internal movement of the lower cover is restricted by a pressing tube member capable of vertical displacement, and the top end of the pressing tube member is mounted with an inner plug member.

[0007] The pipe pressing member includes a variable diameter inner tube that is wider at the top and narrower at the bottom, an annular clamping groove is provided on the outer side of the top end of the variable diameter inner tube, and a resistance ring is provided on the outer side of the bottom end of the variable diameter inner tube to increase the sliding resistance between the variable diameter inner tube and the lower cover;

[0008] The inner plug includes an inner plug cover, and a snap ring that cooperates with the annular snap groove is provided on the inner side of the periphery of the inner plug cover. The middle activity limit of the inner plug cover is limited by a rotating block that can rotate horizontally. The lower end of the rotating block is fixed with a scraping shaft that passes through the inner plug cover. The upper side end of the scraping shaft is supported by an upper scraping blade via a first bracket, and the lower side end of the scraping shaft is supported by a lower scraping blade via a second bracket. The upper end of the rotating block is symmetrically fixed with a foldable pull ring.

[0009] Furthermore, in the above-mentioned push-to-inject functional bottle cap, the lower cover includes a connecting ring, a cylindrical tube, a reducing outer tube, a connecting clamping tube, an anti-slip ring and an aluminum foil piece. The lower side of the outer end of the connecting ring is connected to the cylindrical tube, the inner end of the connecting ring is connected to the reducing outer tube, the upper end of the connecting ring is provided with a connecting clamping tube for facilitating clamping with the upper cover, the inner side of the top end of the reducing outer tube is provided with an anti-slip ring, and the bottom end of the reducing outer tube is installed with an aluminum foil piece.

[0010] Furthermore, in the above-mentioned push-injection functional bottle cap, the inner wall of the lower tube of the variable diameter outer tube is tightly against the resistance ring of the tube pressing member.

[0011] Furthermore, in the above-mentioned push-injection functional bottle cap, the upper cover includes an upper cover body, an anti-theft ring and a clamping tube. The upper cover body is connected to the clamping tube through the anti-theft ring. The clamping tube can be clamped with the connecting clamp tube to form an anti-slip structure.

[0012] Furthermore, in the above-mentioned push-injection functional bottle cap, the upper powder scraping leaf is in contact with the upper inner cavity wall of the variable diameter inner tube, and the lower powder scraping leaf is in contact with the lower inner cavity wall of the variable diameter inner tube.

[0013] Furthermore, in the above-mentioned push-injection functional bottle cap, a receiving groove for accommodating the pull ring is provided at the upper end of the inner plug cap.

[0014] The beneficial effects of the utility model are:

[0015] The utility model has a reasonable structural design and is mainly composed of a lower cover, an upper cover, a pressing tube member and an inner plug member, wherein the pressing tube member includes a variable diameter inner tube, an annular clamping groove and a resistance ring, and the inner plug member includes an inner plug cover, a clamping ring, a rotating block, a powder scraping shaft, a first bracket, a powder scraping leaf, a second bracket, a lower powder scraping leaf and a pull ring. When a pressing and injecting operation is required, the upper cover is first separated from the lower cover to expose the pressing tube member and the inner plug member, and then the inner plug member is manually pressed to move the pressing tube member downward and destroy the aluminum foil in the lower cover. At this time, the pull ring of the inner plug member is folded upward to provide a twisting pull ring to drive the rotating block to rotate, and the powder scraper composed of the powder scraping shaft, the first bracket, the powder scraping leaf, the second bracket and the lower powder scraping leaf also rotates accordingly, which can quickly scrape off the powder stored in the variable diameter inner tube and inject it into the bottle body smoothly; then the pull ring is pulled to drive the inner plug member and the pressing tube member to separate from each other, and the pressing tube member is hidden inside the lower cover.
