Description

Technical Field

[0001] This utility model belongs to the field of bottle cap technology and relates to a press-type storage bottle cap. Background Technology

[0002] When out and about, if you want to drink tea, coffee, milk powder, or other instant beverages, you can go to a store to buy them. However, if there isn't a store, you usually need to carry both a water bottle and the beverage packet, which is quite inconvenient. In existing technology, a bottle cap has the beverage ingredients sealed at the bottom. To use it, you must first manually tear off the bottom seal before attaching the cap to the bottle to add the beverage ingredients to the liquid inside. This method is also quite cumbersome, and tearing off the seal carries the risk of tipping over the cap and spilling the beverage ingredients. In response to this situation, a press-type bottle cap has emerged on the market, such as the press-type bottle cap described in Chinese Patent No. "202420064159.9". It includes an outer cylinder, an elastic pressing dome is provided on the upper inner side of the outer cylinder, and an inner cylinder coaxial with the outer cylinder is provided on the inner side of the elastic pressing dome; a sealing film is provided at the end of the inner cylinder, and a perforating cone for piercing the sealing film is provided on the inner side of the elastic pressing dome; and a thread for connecting the bottle mouth is provided on the inner side of the outer cylinder. In the above structure, when you want to drink a beverage, you only need to press the elastic pressing dome to allow the perforating cone to pierce the sealing film, and the beverage ingredients will fall into the bottle. However, the piercing point of the perforating cone is located in the center of the sealing film and the piercing point is relatively small, which results in a slow feeding speed. In addition, there is a possibility that the beverage ingredients are blocked by the edge of the unpierced sealing film, resulting in some beverage ingredients remaining and not being fully released. At the same time, since the piercing path of the perforating cone to the sealing film is uncontrollable and the shape of the rupture is irregular, it is easy to cause material blockage or inconsistent flow rate. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a press-type storage bottle cap with a large discharge port.

[0004] The objective of this utility model can be achieved through the following technical solution: A press-type storage bottle cap includes a storage cap body installed on the bottle mouth and a sealing layer located inside the storage cap body. A storage space for storing materials is formed between the inside of the storage cap body and the upper surface of the sealing layer. The top of the storage cap body is an elastic pressing part. Multiple pressure columns for breaking the sealing layer are provided on the inner side of the elastic pressing part. When the elastic pressing part is pressed down, the elastic pressing part deforms as it moves downward. The elastic pressing part drives the multiple pressure columns to move downward. The deformation of the elastic pressing part causes the multiple pressure columns to tilt in opposite directions. At the same time, the bottom of the pressure columns contacts the sealing layer and breaks the sealing layer.

[0005] In the aforementioned press-type storage bottle cap, the sealing layer is provided with multiple evenly distributed fragile grooves, which are distributed from the center of the sealing layer to the edge of the sealing layer.

[0006] In the aforementioned press-type storage bottle cap, the sealing layer is divided into multiple unbreakable zones by the fragile groove. The number of unbreakable zones is the same as the number of pressure columns. The multiple pressure columns are located directly above the multiple unbreakable zones. Each pressure column applies force to one unbreakable zone. When the pressure column moves down, the fragile groove breaks, and all the unbreakable zones separate from each other along the fragile groove. The sealing layer is evenly divided and fan-shaped from the center outward.

[0007] In the aforementioned press-type storage bottle cap, the cross-section of the pressing column is approximately triangular, and the opposite sides of the multiple pressing columns are the sides where the long side of the pressing column is located. The sides of the pressing column are provided with reinforcing ribs, and the reinforcing ribs extend to the bottom of the elastic pressing part.

[0008] The aforementioned press-type storage bottle cap also includes a protective cap body. The bottom of the protective cap body is provided with an anti-theft ring. The top of the anti-theft ring is connected to the bottom of the protective cap body through multiple connection points. The side of the anti-theft ring is provided with a pull ring opening. The end of the anti-theft ring is provided with a pull ring force application part. The pull ring force application part is located inside the pull ring opening. The outer circumference of the storage cap body is provided with a positioning step. The protective cap body is fitted onto the storage cap body, and the bottom of the anti-theft ring contacts the positioning step.

[0009] In the aforementioned press-type storage bottle cap, when it is necessary to open the storage space, the pull ring is held and force is applied outward to break the connection point. The anti-theft ring is disengaged from the protective cap, and the protective cap is pressed down. The protective cap drives the elastic pressing part to move down synchronously, causing the pressing column to break the sealing layer.

[0010] In the aforementioned press-type storage bottle cap, the inner circumferential surface of the protective cap is provided with several first limiting plates, and the outer circumferential surface of the storage cap is provided with several second limiting plates. When the protective cap is rotated, the first limiting plates come into contact with the second limiting plates, causing the storage cap to rotate synchronously with the protective cap, and the bottle opening is activated.

[0011] In the aforementioned press-type storage bottle cap, the outer circumferential surface of the storage cap body is provided with a guide ring and an anti-detachment annular groove located at the bottom of the guide ring. The guide ring is provided with a guide slope. The inner circumferential surface of the protective cap body is provided with a protruding anti-detachment block. The bottom of the inner circumferential surface of the anti-theft ring is provided with an anti-theft block, and the anti-theft block is engaged in the anti-detachment annular groove.

[0012] In the aforementioned press-type storage bottle cap, after the anti-theft ring is pulled open, the protective cap is pressed down, the anti-detachment block passes through the guide ring and is engaged in the anti-detachment annular groove, and the bottom of the protective cap contacts the positioning step.

[0013] Compared to existing technologies, the multiple pressure posts in this press-type storage bottle cap create multiple breaking points on the sealing layer, resulting in uniform force distribution. Multiple easily broken grooves are incorporated, with each pressure post applying force to a specific area to be broken. As the pressure post moves downward, the easily broken groove breaks, causing all areas to separate simultaneously along these grooves. This refines the breaking path of the sealing layer, allowing it to break open in a fan-shaped pattern from the center outwards, creating a larger discharge opening. Simultaneously, the tilting movement of the pressure posts further expands the discharge opening towards the edge of the sealing layer, effectively preventing material residue and ensuring that the material falls fully, smoothly, and quickly into the liquid inside the bottle, improving mixing efficiency. Furthermore, even after the sealing layer breaks, its edge remains connected to the storage cap, preventing it from falling into the beverage and causing contamination. The protective cap protects the elastic pressing part from accidental pressure due to external environmental influences. Attached Figure Description

Detailed Implementation

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-4As shown, this press-type storage bottle cap includes a storage cap body 2 installed on the bottle mouth and a sealing layer 1 located inside the storage cap body 2. A storage space for storing materials is formed between the interior of the storage cap body 2 and the upper surface of the sealing layer 1. The top of the storage cap body 2 is an elastic pressing part 21, and multiple pressure pillars 22 for breaking the sealing layer 1 are provided on the inner side of the elastic pressing part 21. When the elastic pressing part 21 is pressed down, it deforms as it moves downward. The elastic pressing part 21 drives the multiple pressure pillars 22 to move downward. The deformation of the elastic pressing part 21 causes the multiple pressure pillars 22 to tilt in opposite directions. At the same time, the bottom of the pressure pillars 22 contacts the sealing layer 1 and breaks the sealing layer 1. The arrangement of multiple pressure columns 22 results in multiple breaking force points on the sealing layer 1, making the sealing layer 1 subjected to uniform force; at the same time, the multiple pressure columns 22 tilt in opposite directions as the elastic pressing part 21 moves downward, that is, after the pressure columns 22 break through the sealing layer 1, the material discharge port on the sealing layer 1 becomes larger as the pressure columns 22 continue to tilt, accelerating the material discharge.

[0021] In the above technical solution: the sealing layer 1 is provided with multiple evenly distributed fragile grooves 11, which are distributed from the center of the sealing layer 1 to the edge of the sealing layer 1.

[0022] In the above technical solution: the sealing layer 1 is divided into multiple areas to be broken by the easily broken grooves 11. The number of areas to be broken is the same as the number of pressure pillars 22. The multiple pressure pillars 22 are located directly above the multiple areas to be broken, ensuring that each area to be broken has a corresponding pressure pillar 22 to break it. The number of pressure pillars 22 is the same as the number of easily broken grooves 11. In this application, there are four easily broken grooves 11, four areas to be broken, and four pressure pillars 22. Multiple easily breakable grooves 11 are provided, with each pressure column 22 applying force to a corresponding area to be broken. As the pressure column 22 moves downward, the easily breakable grooves 11 break, and all areas to be broken simultaneously separate along the easily breakable grooves 11, refining the breaking path of the sealing layer 1. This causes the sealing layer 1 to break open in a fan shape from the center outward, forming a larger discharge port. At the same time, the tilting movement of the pressure column 22 causes the discharge port to continue to expand towards the edge of the sealing layer 1, increasing the discharge port size and effectively avoiding material residue. This ensures that the material can fall fully, smoothly, and quickly into the liquid in the bottle, improving the mixing effect. Furthermore, after the sealing layer 1 breaks, the edge of the sealing layer 1 remains connected to the storage cap 2, preventing the sealing layer 1 from falling into the beverage and causing contamination.

[0023] In the above technical solution: the cross-section of the pressure column 22 is approximately triangular, and the opposite sides of the multiple pressure columns 22 are the sides where the long side of the pressure column 22 is located. The side of the pressure column 22 is provided with reinforcing ribs 27, which extend to the bottom of the elastic pressing part 21.

[0024] The above technical solution also includes a protective cover 3, with an anti-theft ring 4 at the bottom. The top of the anti-theft ring 4 is connected to the bottom of the protective cover 3 through multiple connection points 42. The anti-theft ring 4 has a pull ring opening on its side and a pull ring force application part 41 at its end, located within the pull ring opening. A positioning step 28 is provided on the outer circumference of the storage cover 2. The protective cover 3 is fitted onto the storage cover 2, with the bottom of the anti-theft ring 4 contacting the positioning step 28 to prevent the protective cover 3 from accidentally shifting downwards relative to the storage cover 2. The protective cover 3 protects the elastic pressing part 21, preventing it from being accidentally pressed down due to external environmental influences. When it is necessary to open the storage space, hold the pull ring force application part 41 and apply force outward to break the connection point 42. The anti-theft ring 4 is separated from the protective cover 3. Press down on the protective cover 3. The protective cover 3 drives the elastic pressing part 21 to move down synchronously, so that the pressure column 22 breaks through the sealing layer 1. The elastic pressing part 21 can be pressed without removing the protective cover 3.

[0025] In the above technical solution: the inner circumferential surface of the protective cover 3 is also provided with a number of first limiting plates 33, and the outer circumferential surface of the storage cover 2 is also provided with a number of second limiting plates 25. When the protective cover 3 is rotated, the first limiting plates 33 and the second limiting plates 25 come into contact with each other, so that the storage cover 2 rotates synchronously with the protective cover 3, and the bottle mouth is opened without having to open the protective cover 3.

[0026] In the above technical solution: the elastic pressing part 21 protrudes upward in an arc shape, and a pressing protrusion 26 is provided in the middle of the top of the elastic pressing part 21. A pressing groove 34 is provided on the inner side of the top of the protective cover 3. The pressing protrusion 26 is located in the pressing groove 34 to position the fit between the protective cover 3 and the elastic pressing part 21. When the protective cover 3 moves down, the bottom of the pressing groove 34 applies targeted force to the pressing protrusion 26, causing the middle of the elastic pressing part 21 to move down and drive the elastic pressing part 21 to deform into a state of concave center.

[0027] In the above technical solution: the outer circumferential surface of the storage cover 2 is provided with a guide ring 23 and an anti-detachment annular groove 24 located at the bottom of the guide ring 23, and a guide slope is formed on the guide ring 23. The inner circumferential surface of the protective cover 3 is provided with a protruding anti-detachment block 31. The bottom of the inner circumferential surface of the anti-theft ring 4 is provided with an anti-theft block 43, which is engaged in the anti-detachment annular groove 24 to prevent the protective cover 3 and the anti-theft ring 4 from accidentally moving upward and detaching from the storage cover 2. After the anti-theft ring 4 is pulled open, the protective cover 3 is pressed down, the anti-detachment block 31 passes through the guide ring 23 and is engaged in the anti-detachment annular groove 24, and the bottom of the protective cover 3 contacts the positioning step 28, positioning the protective cover 3 in the pressed-down state to prevent the protective cover 3 from accidentally moving upward and detaching from the storage cover 2.
