Technical Field

[0001] The invention particularly relates to a material-storing bottle cap. Background Art

[0002] Most of the beverage bottles on the market are equipped with bottle caps. Consumers can drink the beverages by unscrewing the bottle caps after purchasing them. However, some beverages require auxiliary materials such as additives, so separate bottle caps have appeared. Separate beverage bottle caps usually place additives in advance in the internal cavity of the bottle cap. After opening the bottle cap, consumers can blend the additives with the solution into beverages. For the specific structure, please refer to the patent scheme of the inventor's previous application for patent number CN202322835761.6, entitled A Separate Bottle Cap Convenient Unsealing Structure.

[0034] Embodiment 1

[0035] The present invention introduces a storage bottle cap for connecting and sealing a beverage bottle. Figures 1 to 4As shown, the bottle cap structure includes a bottle cap seat 1 and a sealing member 2, the bottle cap seat 1 is provided with a storage cavity 10 with an open top, the sealing member 2 seals the opening of the storage cavity 10 so that the sealing member 2 and the inner wall of the storage cavity 10 form a closed storage space for storing materials, the bottom of the storage cavity 10 is composed of a thin-walled bottom plate 11, the middle of the thin-walled bottom plate 11 is provided with a boss 12 protruding upward, the thin-walled bottom plate 11 is provided with an annular tear groove 13 surrounding the boss 12, the thin-walled bottom plate 11 is also provided with at least one radial tear groove 14, one end of the radial tear groove 14 is connected to the annular tear groove 13 and the other end extends outward, wherein these radial tear grooves and annular tear grooves can be formed by cutting or making material thinning areas during injection molding. The middle part of the cover member 2 is provided with a deformable pressing portion 21 for being pressed by a hand, and the pressing portion 21 is connected to a pressing column 22 which can press against the thin-walled bottom plate 11 when it is pressed downward, and the lower end of the pressing column 22 is provided with a receiving groove 23 for accommodating the boss 12, and the pressing column 22 is provided with a piercing portion 24 for piercing the annular tearing groove 13 or the radial tearing groove 14 around the receiving groove 23. When in use, the pressing column 22 presses the thin-walled bottom plate 11 downward, and at the same time, because the boss 12 is embedded in the receiving groove 23, the boss 1 The material at 2 moves downward as a whole, and under the guidance of the accommodating groove 23, the boss 12 will not tilt or swing, so that the middle part of the thin-walled bottom plate 11 is deformed vertically downward, and the stress is concentrated between the material at the boss 12 and other parts of the thin-walled bottom plate 11, so that the boss 12 is preferentially torn locally from the thin-walled bottom plate 11. At the same time, since the middle part of the thin-walled bottom plate 11 is stably and vertically deformed downward, the tearing tension on each radial tear groove 14 is more uniform, so that the tearing area is more evenly distributed in the circular area centered on the boss 12, such as Figure 5 As shown, a relatively uniform break is formed, so that the material stored in the material storage chamber 10 can flow into the beverage bottle quickly and stably for mixing.

[0036] As a preference, Figure 3 As shown, the pressing column 22 is composed of a plurality of supporting plates 221 distributed along the circumference with the receiving groove 23 as the center, and each supporting plate 221 is connected at one end and extends outward at the other end to form a star shape, and the receiving groove 23 is opened at the central position where each supporting plate 221 is connected and the supporting plate 221 is partially hollowed out, and the lower end of the supporting plate 221 can constitute the piercing portion 24. Figure 2 and Figure 3 As shown, the lower end of the support plate 221 is provided with a tip located above the annular tearing groove 13 , and the tip constitutes the piercing portion 24 .

[0037] As a preference, Figure 2 and Figure 3As shown, the thin-walled bottom plate 11 is a concave shape that gradually tilts downward from the periphery to the middle, and the lower edge of the support plate 221 is gradually tilted downward from the periphery to the middle, so that the lower end of the support plate 221 forms a pointed tip, and the tilt angle of the lower edge of the support plate 221 is greater than the tilt angle of the thin-walled bottom plate 11. Figure 2 As shown, the inclination angle α of the lower edge of the support plate 221, and the inclination angle β of the thin-walled bottom plate 11 at the corresponding position of the support plate 221, so that the area of ​​the piercing portion 24 against the thin-walled bottom plate 11 is smaller, the friction force is increased, and the stress is concentrated at the contact point between the piercing portion 24 and the thin-walled bottom plate 11.

[0038] As a preference, Figures 2 to 4 As shown, the edge of the sealing member 2 is provided with a connecting ring 25 surrounding the opening of the material storage chamber 10 and tightly connected to the bottle cap seat 1, and the bottle cap seat 1 is provided with an annular mounting surface 16 around the opening of the material storage bin, and the connecting ring 25 matches the shape of the annular mounting surface 16, and the connecting ring 25 is connected to the annular mounting surface 16 by bonding or hot pressing process, and of course, it can also be connected by glue bonding and other methods.

[0039] Embodiment 2

[0040] like Figure 6 and Figure 7 As shown, the present invention introduces a material storage type bottle cap, which is different from the first embodiment in that the material storage type bottle cap also includes a protective cover 3. The material storage type bottle cap consists of a bottle cap seat 1, a sealing member 2 and the protective cover 3. The protective cover 3 is mounted on the bottle cap seat 1 from top to bottom and covers the sealing member 2.

[0041] As a preference, Figure 6 and Figure 7 As shown, the outer wall of the protective cover 3 is provided with an operating groove 31 for manual operation, the outer wall of the bottle cap seat 1 is provided with a snap ring groove 17, and the inner wall of the protective cover 3 is provided with a snap ring 32 that can be snapped into the snap ring groove 17.

[0042] Embodiment 3

[0043] like Figure 6 and Figure 7As shown, the present invention introduces a material storage type bottle cap, which is different from the first embodiment in that the material storage type bottle cap also includes a protective cover 3. The material storage type bottle cap is composed of a bottle cap seat 1, a sealing member 2 and a protective cover 3. The pressing portion 21 protrudes upward for manual pressing. The top of the protective cover 3 is provided with a cover stopper 33 which is arranged corresponding to the pressing portion 21 and arched upward. The outer side wall of the bottle cap seat 1 is provided with a plurality of vertically arranged clamping grooves 18. The inner side wall of the protective cover 3 is provided with a vertically arranged clamping rib 34 which can be clamped into the clamping groove 18.

[0044] Embodiment 4

[0045] In this embodiment, the thin-walled bottom plate 11 is provided with three bending grooves 15, which are connected end to end to form a polygonal structure with the boss 12 as the center. The radial tear grooves 14 correspond in number to the bending grooves 15, and the radial tear grooves 14 are connected to the annular tear groove 13 and the other end is connected to the end point of the bending groove 15. Figure 3 and Fig.11 As shown, three bending grooves 15 and radial tear grooves 14 are provided, and the bending grooves 15 form a triangle. The bending grooves 15 enclose a tear area A, and the radial tear grooves 14 divide the tear area A into multiple fragment areas A1. When the user presses the pressing part 21 downward, the pressing column 22 presses on the bottom of the thin-walled bottom plate 11, so that the bottom of the thin-walled bottom plate 11 is deformed. After the bottom of the thin-walled bottom plate 11 is deformed, stress concentration is first generated at the position of the radial tear groove 14, and then the bottom of the thin-walled bottom plate 11 is torn along the length direction of the radial tear groove 14. Because the bending grooves 15 enclose a polygonal structure and surround the boss 12, when the boss 12 is subjected to a downward thrust, the tear area A surrounded by the bending grooves 15 is more easily deformed, and the material outside the tear area A is less affected. At the same time, since the radial tear groove 14 extends from the end point of the polygon to the center, the rupture area A is divided into three evenly distributed fragment areas A1. When the top pressure column 22 is pressed downward, stress concentration can be first generated at a position close to the center of the radial tear groove 14, so that the radial tear groove 14 is gradually torn from the center to the surrounding areas, and each fragment area A1 is separated, avoiding problems such as large resistance of the top pressure column 22 and tilt of the top pressure column 22 due to uneven resistance on all sides when the top pressure column 22 is pressed downward, so that the bottom of the thin-walled bottom plate 11 is evenly cracked from the boss 12 along the radial tear groove 14 to the surrounding areas, and the cracked rupture is regular and uniform, ensuring fast and uniform discharge.

[0046] As a preference, Figure 2 As shown, the waistline 151 on the side close to the boss 12 and the waistline 152 on the side away from the boss 12 of the cross section of the bending groove 15 can be seen to have a gentler slope. In this way, when the radial tear groove 14 is cracked, the material in each fragment partition A1 can be deformed and bent at the bending groove 15.

[0047] As a better implementation, Fig.11 As shown, the piercing portions 24 are provided with two and are evenly distributed along the circumference, that is, the angle between the two piercing portions 24 along the center of the circle is 180°, and the radial tear grooves 14 are evenly distributed along the circumference, that is, the angle between each radial tear groove 14 is 120°, so that no matter what angle the cover 2 is rotated, there is at least one piercing portion 24 that falls on the position corresponding to the fragment partition A1, so that the cover 2 can be installed at any angle without affecting the pressing effect of the pressing column 22 on the thin-walled bottom plate 11. In this embodiment, the pressing column 22 is still composed of a plurality of support plates 221, and two of the support plates 221a extend downward and are longer than the other support plates 221b, and the lower ends of the two support plates 221a constitute the piercing portion 24.

[0048] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
