Description

Technical Field

[0001] This utility model relates to the field of bottled beverage production technology, and in particular to a solid-liquid separation bottle cap. Background Technology

[0002] Beverages are typically pre-formulated at the factory, meaning the flavor, concentration, and sugar content of each bottle are fixed after production and cannot be altered by consumers. Furthermore, most bottled beverages contain preservatives to extend their shelf life. This is especially true for probiotics and protein powders, whose active ingredients have a short lifespan after contact with water, necessitating the addition of large amounts of preservatives. However, these preservatives not only affect the original flavor of the beverage but also pose certain side effects. Long-term excessive intake can harm consumers' health, especially for vulnerable groups such as children, the elderly, and pregnant women.

[0003] Patent CN222845720U discloses a detachable beverage bottle cap comprising a storage section, a connecting section, and a sealing section. The storage section includes a storage tube and a screw cap fixed to one end of the storage tube, with the other end of the storage tube open. The connecting section includes a connecting tube and a screw cap fixed to the outer side of the middle section of the connecting tube, with external threads on the upper outer side of the connecting tube. The sealing section includes a cap with a slot on its edge that matches the lower end of the storage tube; the lower end of the storage tube is inserted into the slot with an interference fit; a connecting ring is fitted on the lower outer side of the connecting tube, and the connecting ring is connected to the cap via a connecting strap. This application allows the powder to quickly fall into the beverage bottle by twisting the cap off, making the operation simple and convenient. However, it can only release one type of powder into the beverage bottle, therefore consumers cannot change the taste, concentration, or sweetness of the beverage according to their preferences. Utility Model Content

[0004] The technical problem to be solved by this utility model is to improve a solid-liquid separation bottle cap, which solves the problem that current separation beverage bottle caps cannot change the flavor, concentration or sweetness according to consumer preferences.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A solid-liquid separation bottle cap includes a main cap for screwing onto the bottle neck and a powder hopper vertically slidably connected inside the main cap. At least two hoppers are distributed along the circumference of the main cap. Each hopper has an opening at its bottom, and a sealing film is fixedly connected to the opening at the bottom of each hopper. A blade with an upward-facing edge is fixedly connected to the bottom of the main cap at a position corresponding to each hopper. A snap-fit ​​part is fixedly connected to the top of each hopper, and each snap-fit ​​part is sealed through the main cap. A button is fixedly connected to the top of each snap-fit ​​part on the main cap.

[0007] Furthermore, the top of the main cover is a top plate, and the top plate has holes at positions corresponding to each snap-fit ​​part. The top plate has a second snap ring at the bottom of the holes. The snap-fit ​​part is cylindrical, and the middle of the snap-fit ​​part is an outwardly protruding elastic first snap ring. The outer diameter of the first snap ring is larger than the inner diameter of the second snap ring. The second snap ring is engaged in the lower annular groove between the first snap ring and the hopper. When the button is pressed, the snap-fit ​​part moves down, and the second snap ring is engaged in the upper annular groove between the first snap ring and the button.

[0008] Furthermore, the main cover includes a vertically arranged central column, an intermediate sleeve, and an outer sleeve arranged coaxially from the inside to the outside. The top of the outer sleeve is provided with a top plate. The central column, intermediate sleeve, and outer sleeve are all fixedly connected to the top plate. The hopper is slidably connected between the central column and the intermediate sleeve. The blade is fixedly connected to the intermediate sleeve. There is a gap between the outer sleeve and the inner sleeve. The bottle mouth sidewall is located in the gap. The outer sleeve is threadedly connected to the bottle mouth. The intermediate sleeve is sealed to the bottle mouth. The snap-fit ​​part is provided through the top plate.

[0009] Furthermore, a blade holder is provided at the bottom of the blade, the blade holder includes an inner ring and an outer ring arranged coaxially, and a support rod is fixedly connected to the inner ring and the outer ring at a position corresponding to each hopper. The blade is fixedly connected to the corresponding support rod, the inner ring is fixedly connected to the central column, and the outer ring is fixedly connected to the intermediate sleeve.

[0010] Furthermore, an annular sealing ring is fixedly connected to the outer wall of the intermediate sleeve near the top. After the bottle is screwed onto the outer sleeve, the sealing ring seals against the inner wall of the bottle opening.

[0011] Furthermore, a protective ring is fixedly provided on the top of the main cover, and all the buttons are located inside the protective ring. A secondary cover is provided on the protective ring.

[0012] Furthermore, the blade is cross-shaped or trident-shaped, with a higher center and lower edges, and the blade material is hard plastic.

[0013] Furthermore, the sealing film is one of aluminum foil, tin foil, or plastic film.

[0014] Furthermore, the bottom of the button is a boss, the upper end of the snap-fit ​​part is fixedly connected to the boss, and the top of the hole is a recess for engaging with the boss.

[0015] The positive effects of this utility model are:

[0016] This invention features a main cap containing at least two hoppers. The bottom of each hopper has an opening sealed with a sealing film. A blade is located at the bottom of the main cap, and a button is positioned above it. After the main cap is screwed onto the bottle neck, pressing the button releases the powder from the corresponding hopper into the bottle, where it mixes with the water. This invention allows consumers to customize the flavor, concentration, or sweetness of the beverage. Because the powder is located in a sealed space within the hopper, it is protected from outside air, moisture, and contamination, and can be stored for extended periods without the need for preservatives. The powder is only mixed with water before consumption, resulting in a purer and better-tasting beverage comparable to commercially available ready-to-drink beverages. Attached Figure Description

[0024] Example 1

[0025] like Figures 1 to 5 As shown, a solid-liquid separation bottle cap includes a main cap 17 and a hopper 9 vertically slidably connected within the main cap 17. The hoppers 9 are three independent hoppers distributed along the circumference of the main cap 17. Each hopper 9 has a fan-shaped cross-section and an opening at its bottom. A sealing film 13 made of aluminum foil is welded to the opening at the bottom of each hopper 9, thus forming a closed space inside the hopper 9. Each of the three hoppers 9 stores powder 11.

[0026] At the bottom of the main cover 17, blades 14 with upward-facing cutting edges are fixedly connected to the corresponding parts of each hopper 9. At the top of each hopper 9, a snap-fit ​​part 8 is fixedly connected. Each snap-fit ​​part 8 is sealed through the main cover 17. A disc-shaped button 7 is fused to the top of each snap-fit ​​part 8 on the top of the main cover 17.

[0027] The top of the main cover 17 is a circular top plate 3. Each top plate 3 has a hole corresponding to each snap-fit ​​part 8. Below each hole on the top plate 3 is a second snap ring 19. Each snap-fit ​​part 8 is cylindrical, and in the center of each snap-fit ​​part 8 is an outwardly protruding, elastic first snap ring 18. Both the first snap ring 18 and the second snap ring 19 have semi-circular cross-sections. The outer diameter of the first snap ring 18 is larger than the inner diameter of the second snap ring 19. The second snap ring 19 is engaged in the lower annular groove between the first snap ring 18 and the hopper 9.

[0028] The bottom center of the button 7 is a frustum-shaped boss 20 that is larger at the top and smaller at the bottom. The upper end of the snap-fit ​​part 8 is fused to the center of the boss 20. The top of the hole is a recess 21 for engaging with the boss 20.

[0029] In use, first tighten the main cap 17 onto the bottle neck 16, then press the corresponding button 7. The corresponding locking part 8 moves down, and the second locking ring 19 engages in the upper annular groove between the first locking ring 18 and the button 7. The boss 20 enters the corresponding recess 21, and the bottom surface of the button 7 abuts against the top surface of the top plate 3. When the locking part 8 moves down, it causes the corresponding hopper 9 to move down, and the blade 14 punctures the sealing film 13 at the bottom of the corresponding hopper 9. Then shake the bottle 16, and the corresponding powder 11 will enter the bottle 16 and mix with the water inside the bottle 16. After that, unscrew the main cap 17, and it is ready to drink.

[0030] The engagement of the snap-fit ​​part 8 and the top plate 3 can limit the hopper 9 to two positions, preventing the hopper 9 from moving accidentally during storage and transportation, which would cause the sealing film 13 to be punctured prematurely and thus cause the powder 11 to be released prematurely.

[0031] If all three hoppers 9 store the same flavor of powder 11, the concentration of the beverage after mixing the powder 11 with water can be adjusted by puncturing different numbers of sealing films 13 to suit the needs of different consumers.

[0032] If different flavored powders 11 are stored in three silos 9, then by puncturing different sealing films 13, a beverage with one flavor, or a mixture of two or three flavors can be formed.

[0033] Alternatively, powder 11 can be added to one of the three hoppers 9, while sugar is added to the other two, thus adjusting the sweetness of the beverage.

[0034] This invention can be manufactured and sold as a separate product. Before leaving the factory, the bottom of the outer casing 1 is sealed with an easy-tear film (refer to the sealing film on existing medicine bottles) for use with bottled water on the market. Alternatively, it can be packaged as a whole with bottled water before leaving the factory.

[0035] Therefore, this invention allows for the modification of the beverage's flavor, concentration, or sweetness according to consumer preferences. Because the powder 11 is located in a sealed space within the hopper 9, it is not exposed to outside air, nor is it susceptible to moisture or contamination. Furthermore, it can be stored for a long time without the need for preservatives. The powder 11 is only mixed with water before consumption, resulting in a purer and better-tasting beverage comparable to commercially available ready-to-drink beverages.

[0036] Example 2

[0037] The difference between this embodiment and Embodiment 1 is that:

[0038] The main cover 17 also includes a vertically arranged central column 5, an intermediate sleeve 2, and an outer sleeve 1, arranged coaxially from the inside to the outside. The central column 5 is cylindrical, and the intermediate sleeve 2 and outer sleeve 1 are both cylindrical. The central column 5, intermediate sleeve 2, and outer sleeve 1 are all fixedly connected to the top plate 3. The hopper 9 is slidably connected between the central column 5 and the intermediate sleeve 2. The lower end of the intermediate sleeve 2 and the lower end of the central column 5 are both fixedly connected to the blade 14. There is a gap 12 between the outer sleeve 1 and the inner sleeve, and the bottle mouth sidewall of the bottle 16 is located within this gap 12.

[0039] The outer wall of the intermediate sleeve 2 is fixedly connected with an annular sealing ring 10 near the top, and the inner wall of the outer sleeve 1 is threaded. After the bottle 16 is screwed onto the outer sleeve 1, the outer sleeve 1 is threadedly connected to the bottle mouth of the bottle 16, and the sealing ring 10 relies on elasticity to seal against the inner wall of the bottle mouth, with the bottle mouth resting against the bottom of the top plate 3.

[0040] Example 3

[0041] The difference between this embodiment and Embodiment 2 is that:

[0042] The blade 14 has a blade holder 15 at its bottom. The blade holder 15 includes an inner ring and an outer ring arranged coaxially. Support rods are fixedly connected to the inner and outer rings at positions corresponding to each hopper 9. The blade 14 is fixedly connected to the corresponding support rod. The inner ring is fixedly connected to the central column 5, and the outer ring is fixedly connected to the intermediate sleeve 2. The blade 14 is cross-shaped, with a higher center and lower edges. The blade 14 and the blade holder 15 are integrally molded from rigid plastic. The cross-shaped blade 14 can form a cross-shaped cut on the sealing film 13, making it easier for the powder 11 to be released.

[0043] A retaining ring 4 is fixedly installed on the top of the main cover 17, and the three buttons 7 are all located inside the retaining ring 4. A secondary cover 6 is placed on top of the retaining ring 4. The secondary cover 5 can be connected to the retaining ring 4 by a sleeve or by a threaded connection.

[0044] Only after opening the secondary cover 6 can the corresponding button 7 be pressed, thereby preventing the button 7 from being accidentally pressed during storage and transportation, which could lead to the premature release of the powder 11.

[0045] During manufacturing, the outer sleeve 1, intermediate sleeve 2, central column 5, top plate 3, retaining ring 4, and sealing ring 10 can be integrally molded from plastic. The sealing ring 10 is made of soft plastic, while the rest is made of hard plastic. The hopper 9 and the snap-fit ​​part 8 are integrally molded and then welded to the button 7 after being installed on the main cover 17. After that, the intermediate sleeve 2 and the central column 5 are welded to the tool holder 15 respectively.

[0046] In actual production, the hoppers 9 containing different powders 11 can be combined according to different needs, thereby enriching the variety of products of this invention and meeting the taste requirements of different consumers. Different markings or direct printing of the names of the powders 11 on the buttons 7 allow consumers to intuitively see the flavor of the beverage to be prepared, facilitating their selection.
