Description

Technical Field

[0001] This invention relates to the field of bottle cap technology, specifically to a bottle cap assembly with a penetrable ingredient compartment. Background Technology

[0002] A bottle cap is a container seal used to seal the mouth of a bottle. It protects the contents from external contamination and maintains the airtight seal of the gas and liquid inside. Some medications or beverages need to be prepared immediately, so the ingredients and liquid are usually stored separately and mixed before use. For example, CN204341651U discloses a storage bottle cap for storing solid or liquid substances, comprising: a bottle cap, a storage cap, a bottle mouth, a lower push ring, an upper push ring, a sealing bottom of the lower push ring, an annular sheet, ratchet teeth on the storage cap, and ratchet teeth on the bottle mouth. The storage cap has an external threaded opening at the top and an internal threaded opening at the bottom. The bottom of the storage cap has a sealed base, and a thin annular sheet connects the sealed base and the storage cap. The interior of the storage cap is a storage space. The bottle cap is screwed onto the external threaded opening at the top of the storage cap. The upper end of the upper push ring is integrated with the top inside the bottle cap. The lower end of the upper push ring has a lower bevel. The lower push ring is located inside the storage cap, and the upper end of the lower push ring has an upper bevel. The lower bevel of the upper push ring mates with the upper bevel of the lower push ring. The internal threaded opening at the bottom of the storage cap is used to screw onto the bottle mouth. The storage cap has a storage cap ratchet, and the bottle mouth has a bottle mouth ratchet. The storage cap ratchet mates with the bottle mouth ratchet.

[0003] For example, as described in the aforementioned literature, in the traditional technology, when the cap assembly with a penetrable filling compartment is used, the bottom of the seal is easily detached and enters the liquid because the bottom of the bottom push ring is horizontal when the lower push ring moves down to tear open the annular sheet. If part of the annular sheet is retained so that the bottom of the seal does not completely detach, the bottom of the seal will obstruct the falling of the filling. Summary of the Invention

[0004] The purpose of this invention is to provide a bottle cap assembly with a permeable ingredient compartment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bottle cap assembly with a penetrable ingredient storage compartment, comprising a main bottle cap and an ingredient storage cylinder integrally disposed in the middle of the main bottle cap. The ingredient storage cylinder is cylindrical, with one end open and the other end closed, its open end facing upwards above the top surface of the main bottle cap. A piercing pressure cylinder is inserted inside the ingredient storage cylinder, with one end open and the other end closed, the open end of the piercing pressure cylinder facing downwards. A limiting annular groove is formed on the surface of the piercing pressure cylinder, and an anti-detachment rib is fixedly provided on the surface of the ingredient storage cylinder. The retaining edge is matched with the limiting ring groove. A protective cover that can be detachably matched with the ingredient storage cylinder is provided above the main bottle cap. The protective cover protects the puncture cylinder inside. The puncture cylinder has a pusher inner plate and a compression spring arranged sequentially from bottom to top inside. A connecting top tube is fixedly provided on the lower surface of the pusher inner plate. The lower end of the connecting top tube extends to the lower inner surface of the ingredient storage cylinder. The connecting top tube has a split impact structure on its inner and outer sides. The split impact structure can impact the lower inner surface of the ingredient storage cylinder during the process of the pusher inner plate descending relative to the puncture cylinder.

[0006] The split impact structure includes a split punch shaft, a fixed shaft disc, a positioning side ring, and a pressure-holding spring. The split punch shaft is inserted into the inside of the connecting top pipe. The upper end of the split punch shaft passes upward through the inner pusher disc and extends a certain distance. The fixed shaft disc is fixedly installed at the upper end of the split punch shaft. The positioning side ring is fixedly installed on the upper surface of the fixed shaft disc. The pressure-holding spring is installed above the fixed shaft disc inside the positioning side ring.

[0007] The surface of the connecting jack is provided with a movable pressure groove, and a lever is inserted inside the movable pressure groove and fixedly installed with the split punch shaft. The inner wall surface of the piercing pressure cylinder is provided with a hidden vertical groove, and the hidden vertical groove is provided with a blocking tooth. The lever and the blocking tooth interfere with each other.

[0008] A fixed outer ring is fixedly provided on the surface of the connecting top pipe, and a rotating sleeve is sleeved on the outside of the connecting top pipe. A limiting inner ridge is fixedly provided on the inner wall surface of the rotating sleeve, and a mating ring groove is opened on the outer surface of the connecting top pipe. The limiting inner ridge is limited and set inside the mating ring groove.

[0009] A rotary torsion spring is provided between the fixed outer ring and the rotary sleeve. The two ends of the rotary torsion spring are fixedly connected to the fixed outer ring and the rotary sleeve respectively. The rotary torsion spring provides elastic rotary torque. A material-pulling plate is fixedly provided on the surface of the rotary sleeve.

[0010] The lower part of the rotating sleeve is fixedly provided with an arc-shaped extrusion plate, and the surface of the connecting top pipe is provided with an extrusion block groove. A lifting extrusion block is provided in the extrusion block groove and is fixedly installed with the split punch shaft. The lifting extrusion block is in a pressing fit with the arc-shaped extrusion plate.

[0011] The inner wall surface of the main bottle cap is provided with a bottle cap thread, and a sealing pressure ring is fixedly provided on the upper inner wall surface of the main bottle cap.

[0012] The inner lower surface of the mixing cylinder is provided with a weak ring groove, the outer surface of the mixing cylinder is provided with an external thread, and the inner wall surface of the protective cover is provided with an internal thread. The external thread and the internal thread are helically engaged.

[0013] The inner wall surface of the puncture cylinder is provided with a limiting wall ring, which is located below the hidden vertical groove. The outer surface of the puncture cylinder is embedded with a sealing rubber ring, and the puncture cylinder is in sealed contact with the inner wall surface of the mixing storage cylinder through the sealing rubber ring.

[0014] The lower end of the puncturing cylinder is provided with a puncturing slope, which corresponds vertically to the weak ring groove. A retention groove is opened on the puncturing slope. An anti-tilting eave is fixedly provided at the edge of the inner pusher disc, and the anti-tilting eave is in limiting contact with the inner wall surface of the puncturing cylinder.

[0015] The beneficial effects of this invention are:

[0016] This invention features a bottle cap assembly with a penetrable ingredient compartment. Compared to traditional bottle cap assemblies with penetrable ingredient compartments, this invention allows the bottom of the ingredient storage cylinder to be pierced by the pressure cylinder. A compression spring and connecting top tube then open the bottom of the cylinder, facilitating the descent of the ingredients. Furthermore, during the opening process, a split impact structure impacts the lower inner surface of the ingredient storage cylinder, causing the bottom to swing repeatedly as it is opened, accelerating the descent of the ingredients and resulting in cleaner, less residue-free descent.

[0017] By using a rotating sleeve and rotating torsion spring, and in conjunction with the movement of the split punch shaft in the process described above, the material feeding plate can reciprocate at a certain amplitude to achieve a stirring effect. When the ingredients clump together, it can disperse the ingredients and reduce the probability of clumping. Attached Figure Description

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 10This invention provides a technical solution: a bottle cap assembly with a penetrable ingredient storage compartment, comprising a main bottle cap 1 and an ingredient storage cylinder 2 integrally disposed in the middle of the main bottle cap 1. The ingredient storage cylinder 2 is cylindrical, with one end open and the other end closed, and its open end facing upwards above the top surface of the main bottle cap 1. A piercing pressure cylinder 3 is inserted inside the ingredient storage cylinder 2, with one end open and the other end closed, and the open end of the piercing pressure cylinder 3 facing downwards. A limiting annular groove 4 is formed on the surface of the piercing pressure cylinder 3, and an anti-detachment rib 5 is fixedly provided on the surface of the ingredient storage cylinder 2. The anti-detachment rib 5 and the limiting annular groove 4 are fixedly provided on the surface of the ingredient storage cylinder 2. The positioning groove 4 provides a limiting fit, and a protective cover 6 is provided above the main bottle cap 1 that is detachably fitted with the ingredient storage cylinder 2. The protective cover 6 protects the puncture cylinder 3 inside. Inside the puncture cylinder 3, from bottom to top, there are a pusher inner plate 7 and a compression spring 8. A connecting top tube 9 is fixedly provided on the lower surface of the pusher inner plate 7. The lower end of the connecting top tube 9 extends to the lower inner surface of the ingredient storage cylinder 2. The inner and outer sides of the connecting top tube 9 are provided with a split impact structure. The split impact structure can impact the lower inner surface of the ingredient storage cylinder 2 during the process of the pusher inner plate 7 descending relative to the puncture cylinder 3.

[0031] The split impact structure includes a split impact shaft 901, a fixed shaft disc 902, a positioning side ring 903, and a pressure-holding spring 904. The split impact shaft 901 is inserted into the connecting jacking pipe 9. The upper end of the split impact shaft 901 passes upward through the inner pusher disc 7 and extends a certain distance. The fixed shaft disc 902 is fixedly installed at the upper end of the split impact shaft 901. The positioning side ring 903 is fixedly installed on the upper surface of the fixed shaft disc 902. The pressure-holding spring 904 is installed above the fixed shaft disc 902 and inside the positioning side ring 903. The pressure-holding spring 904 always works in a compressed state, providing outward elastic force to the connecting jacking pipe. A movable pressure groove 905 is provided through the surface of the cylinder 9. A lever 906, which is fixedly installed with the split punch shaft 901, is inserted inside the movable pressure groove 905. A hidden vertical groove 907 is provided on the inner wall surface of the cylinder 3. A blocking tooth 908 is provided inside the hidden vertical groove 907. The lever 906 and the blocking tooth 908 interfere with each other. The lever 906 is made of tough plastic or metal spring. When subjected to a large pressure from the compression spring 8, the lever 906 and the blocking tooth 908 can undergo elastic deformation, thereby breaking through the blockage of the blocking tooth 908.

[0032] A fixed outer ring 909 is fixedly provided on the surface of the connecting jacking pipe 9. A rotating sleeve 910 is sleeved on the outside of the connecting jacking pipe 9. A limiting inner ridge 911 is fixedly provided on the inner wall surface of the rotating sleeve 910. A mating ring groove 912 is opened on the outer surface of the connecting jacking pipe 9. The limiting inner ridge 911 is limited and set inside the mating ring groove 912.

[0033] A rotating torsion spring 913 is provided between the fixed outer ring 909 and the rotating sleeve 910. The two ends of the rotating torsion spring 913 are fixedly connected to the fixed outer ring 909 and the rotating sleeve 910 respectively. The rotating torsion spring 913 provides elastic rotational torque. A material-pulling plate 914 is fixedly provided on the surface of the rotating sleeve 910.

[0034] A curved extrusion plate 915 is fixedly installed at the lower part of the rotating sleeve 910. An extrusion block groove 917 is opened through the surface of the connecting top pipe 9. A lifting extrusion block 916 is installed in the extrusion block groove 917 and is fixedly installed with the split punch shaft 901. The lifting extrusion block 916 and the curved extrusion plate 915 are pressed together.

[0035] The inner wall surface of the main bottle cap 1 is provided with a bottle cap thread 101, and a sealing pressure ring 102 is fixedly provided on the upper inner wall surface of the main bottle cap 1.

[0036] The inner lower surface of the mixing cylinder 2 is provided with a weak ring groove 201, the outer surface of the mixing cylinder 2 is provided with an external thread 202, and the inner wall surface of the protective cap 6 is provided with an internal thread 601. The external thread 202 and the internal thread 601 are screwed together. The weak ring groove 201 is integrally formed by the mold during the injection molding process of the mixing cylinder 2 and the main bottle cap 1.

[0037] A limiting ring 301 is provided on the inner wall surface of the puncture cylinder 3. The limiting ring 301 can prevent the pusher inner plate 7 and the lever 906 from falling off. The limiting ring 301 is located below the hidden vertical groove 907. A sealing ring 302 is embedded on the outer surface of the puncture cylinder 3. The puncture cylinder 3 is in sealed contact with the inner wall surface of the feeding storage cylinder 2 through the sealing ring 302.

[0038] The lower end of the puncture cylinder 3 is provided with a puncture slope 303, which corresponds to the weak ring groove 201. A retention groove 304 is provided on the puncture slope 303. An anti-tilting eave 701 is fixedly provided at the edge of the inner pusher disc 7, and the anti-tilting eave 701 is in limited contact with the inner wall surface of the puncture cylinder 3.

[0039] In use, the ingredients are stored in a closed space formed by the bottom of the ingredient storage cylinder 2 and the inner cavity of the piercing cylinder 3; the main bottle cap 1 is screwed onto the bottle mouth, and the sealing ring 102 is pressed against the bottle mouth to achieve a seal; when mixing is required, the protective cap 6 is rotated to remove it, and the top of the piercing cylinder 3 is pressed by hand to drive the piercing cylinder 3 downward, so that the piercing cylinder 3 tears the weak ring groove 201 through the piercing inclined surface 303. Since the piercing inclined surface 303 has a retention groove 304, such as Figure 5 and 6 As shown in the figure, it is possible to retain part of the weak ring groove 201 without cutting it off. By connecting part of the weak ring groove 201, it is possible to prevent the bottom of the mixing cylinder 2 from falling completely into the mixture.

[0040] When most of the weak ring groove 201 is cut off, the bottom of the batching cylinder 2 loses its ability to support the connecting top pipe 9. Under the elastic force of the compression spring 8, the connecting top pipe 9 moves downward, thereby opening the bottom of the batching cylinder 2 to facilitate the falling of the batching.

[0041] During the downward movement of the connecting jacking tube 9, the lever 906 interferes with the blocking teeth 908, preventing the split punch shaft 901 from moving downward. At this time, relative movement occurs between the split punch shaft 901 and the connecting jacking tube 9, and the connecting jacking tube 9 moves downward relative to the split punch shaft 901. When the connecting jacking tube 9 moves downward, when the inner upper surface of the movable pressure groove 905 contacts the lever 906, the large elastic force provided by the compression spring 8 acts on the lever 906, causing the lever 906 to undergo elastic deformation due to the interference between the blocking teeth 908 and the lever 906. The lever 906 overcomes the blocking of the blocking teeth 908 and moves downward rapidly under the elastic force of the pressure holding spring 904 until it interferes with the blocking teeth 908 below again, thus completing the cycle.

[0042] Since the split punch shaft 901 is fixed as a whole with the lever 906, the split punch shaft 901 moves downwards in an impacting motion. During the process of the connecting top tube 9 moving down to open the bottom of the batching storage cylinder 2, the split punch shaft 901 impacts the bottom surface of the batching storage cylinder 2, causing the bottom of the batching storage cylinder 2 to swing multiple times while being opened, accelerating the falling of the batching material.

[0043] like Figure 3 As shown, the rotary torsion spring 913 provides an elastic driving force for rotation, so that the rotary sleeve 910 has an elastic tendency to rotate in the direction of counterclockwise when viewed from above; since the lifting extrusion block 916 is fixed integrally with the split punch shaft 901, when the split punch shaft 901 moves up and down relative to the connecting jacking pipe 9, the lifting extrusion block 916 moves up and down synchronously relative to the connecting jacking pipe 9.

[0044] When the lifting extrusion block 916 moves downward, it loses its pressure on the arc-shaped extrusion plate 915. At this time, the rotating sleeve 910 rotates under the action of elastic tendency. When the lifting extrusion block 916 moves upward, it drives the rotating sleeve 910 to rotate in the opposite direction by pressing against the inclined surface of the arc-shaped extrusion plate 915, thus storing the elastic rotation tendency. This causes the rotating sleeve 910 to reciprocate within a certain range and drive the feeding plate 914 to reciprocate, thereby achieving a mixing effect. When the batching clumps, it can disperse the batching and reduce the probability of the batching clumping.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
