Abstract
Description
Technical Field
[0001] The present invention relates to a bottle cap, specifically a beverage bottle cap. Background Art
[0002] As is well known, although traditional beverage packaging has solved the problem of convenience, it has obvious deficiencies in terms of product freshness preservation requirements. Beverages are prone to spoilage after being placed for a long time, which provides a market demand basis for the development of bottle cap technologies for powdered beverages. Through innovative structural designs, the separate storage and instant mixing of solid powders and liquids can be achieved within the same packaging, which not only retains the advantage of the long shelf life of powdered products but also provides a fresh taste experience similar to freshly made beverages. This technology not only solves the limitations of traditional packaging but also conforms to the current demand trends in the beverage market for healthy, convenient, and personalized products.
[0003] By separating the perishable liquid components from the relatively stable solid powders for storage, the common quality deterioration problems of premixed liquid beverages are effectively avoided. Research shows that the growth of microorganisms in powdered components is significantly inhibited in a dry environment, and a shelf life of 12 - 24 months can be achieved without adding preservatives, far exceeding the 3 - 6 months of similar premixed beverages. Moreover, the same basic liquid can be paired with different powder formulas to achieve diversification in taste, function, and even color, meeting the personalized needs of consumers. Summary of the Invention
[0004] Aiming at the above - mentioned defects, the present invention provides a beverage bottle cap that is convenient to use, simple in structure, low in cost, and good in sealing performance, so as to achieve the purpose of making tea beverages or Chinese herbal medicines ready to drink immediately while ensuring the quality of the powder.
[0005] To achieve the above - mentioned purpose, the present invention adopts the following technical solutions: A beverage bottle cap includes a powder storage tank body, a sleeve, and a support sleeve. The top end of the powder storage tank body is a top cover with internal threads, the lower end of the powder storage tank body has external threads, and there is a sealing paper at the opening. The upper half of the support sleeve cylinder body is provided with external threads, and the top cover of the powder storage tank body is screwed together with the external threads on the upper half of the support sleeve to form an integral structure; the lower half of the support sleeve is a lower cover, which is divided into inner and outer layers. The inner side of the outer layer is provided with internal threads that can be screwed with the threads of the mouth of other containers, and the inner side of the inner layer has a guiding chute; the outer wall of the sleeve has a plurality of guiding slide bars, a breaking device is arranged inside the sleeve, the external threads at the lower end of the powder storage tank body are adapted to the internal threads on the inner wall of the outer cylinder, the outer diameter of the inner cylinder is adapted to the inner diameter of the powder storage tank body, and the guiding slide bars are adapted to the guiding chute.
[0006] Preferably, the breaking device is an inner cylinder fixed inside the sleeve. The length of the inner cylinder is less than the length of the outer cylinder, and a spike is provided at the upper end of the inner cylinder.
[0007] Preferably, the upper end of the sleeve has a positioning ring.
[0008] Preferably, the length of the inner cylinder is half of the length of the outer cylinder.
[0009] Preferably, an anti-counterfeiting ring is provided in the middle of the support sleeve.
[0010] The beneficial effects of the beverage bottle cap of the present invention are as follows: The powder in the powder storage tank is sealed with a sealing paper, and the sealing effect is good, which ensures that the powder in the powder storage tank remains dry and does not change its taste, extends the shelf life of the powder, and allows for the instant brewing and drinking of tea beverages or Chinese herbal medicines on the premise of ensuring the quality of the powder; The present invention can be directly installed on any existing bottle with a threaded mouth, thus reducing a large amount of equipment investment and labor investment.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0021] Embodiment 1
[0022] As shown Figure 1-7 in the figure, a beverage bottle cap includes a powder storage tank body 1, a sleeve and a support sleeve 3. The top end of the powder storage tank body 1 is a top cover with an internal thread 4. The lower end of the powder storage tank body 1 has an external thread, and a sealing paper 2 is provided at the opening. The upper half of the cylinder body of the support sleeve 3 is provided with an external thread 5. The top cover of the powder storage tank body 1 is engaged with the external thread groove 5 at the upper half of the support sleeve 3 and can be tightened into an integral structure. The lower half of the support sleeve 3 is a lower cover. The lower cover is a double-layer structure inside and outside. The inner side of the outer layer is provided with an internal thread 4 that can be engaged with the thread groove of the bottle mouth of other containers. The inner side of the inner layer has a plurality of evenly distributed guiding sliding grooves 11. The sleeve is divided into an inner cylinder 8 and an outer cylinder 7. The outer wall of the outer cylinder 7 has a plurality of evenly distributed guiding sliding strips 12. The plurality of evenly distributed guiding sliding strips 12 are adapted to the plurality of evenly distributed guiding sliding grooves 11. The inner wall of the outer cylinder 7 has an internal thread 4. The lower ends of the inner cylinder 8 and the outer cylinder 7 are connected by a plurality of connecting strips 9. The length of the inner cylinder 8 is less than the length of the outer cylinder 7. The upper end of the inner cylinder 8 has a spike 13. The external thread 5 at the lower end of the powder storage tank body 1 is adapted to the internal thread 4 on the inner wall of the outer cylinder 7. When the powder storage tank body 1 is rotated, the outer cylinder 7 can move up and down. The outer diameter of the inner cylinder 8 is adapted to the inner diameter of the powder storage tank body 1. The upper end of the outer cylinder 7 has a positioning ring 10. The length of the inner cylinder 8 is half of the length of the outer cylinder 7.
[0023] A security ring 14 is fixedly provided in the middle of the support sleeve. The security ring 14 is connected to the top cover by a plurality of evenly distributed security strips 15. When the top cover is rotated, the security strips 15 are broken off. The thread rotation direction of the powder storage tank body 1 of the top cover is opposite to the thread rotation direction of the inner side of the outer layer of the lower cover.
[0024] As shown Figure 1 - Figure 7 in the figure, when the beverage bottle cap described in the embodiment of the present invention is in use, first unscrew the upper cover and the powder storage tank body 1 in the reverse direction. The external thread 5 at the lower end of the powder storage tank body 1 meshes and rotates with the external thread 4 on the inner wall of the outer cylinder in the sleeve. The sleeve gradually rises, and the inner cylinder 8 in the sleeve gradually rises. The spike 13 at the upper end of the inner cylinder 8 will pierce the sealing paper 2 at the lower end of the powder storage tank body 1. The powder in the powder storage tank body 1 falls into the bottle body 6. At this time, shake the bottle body 6 to dissolve the powder in the liquid in the bottle, and then unscrew the lower cover to directly drink.
[0025] The above embodiments are one of the more preferred specific embodiments of the present invention. The ordinary changes and substitutions made by those skilled in the art within the scope of this technical solution should be included in the protection scope of the present invention.
