Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to a solid-liquid separation combined bottle cap structure that is pressed down to open a sealed bottom with equally divided openings. Background Art

[0002] A solid-liquid separation bottle cap is a device used to separate liquid from solid materials within a bottle. This device is designed to allow the user to drop the solid material into the liquid within the bottle through a specific operation, achieving a solid-liquid mixing effect. This type of cap is commonly used for beverages, pharmaceuticals, and other products that require mixing. It keeps the solid components dry and fresh while allowing consumers to quickly mix them when needed.

[0003] The patent with publication number CN220949335U discloses a press-combined sealed top-through solid-liquid separation bottle cap, including a bottle cap main body installed on the outside of the bottle mouth, a cap sealing bottom installed at the inner lower end of the bottle cap main body, and a material bin installed on the inner side of the bottle cap main body above the cap sealing bottom, and a material bin force-bearing column installed on the inner upper surface of the material bin, and the bottle cap main body and the cap sealing bottom are integrally formed; the bottle cap main body and the cap sealing bottom for placing solid materials in the utility model are integrally injection molded, and the material bin and the bottle cap main body are stabilized and sealed by the first cap sealing ring, the second cap sealing ring, the first material bin sealing ring and the second material bin sealing ring, thereby effectively preventing water in the bottle from contacting the solid materials; the design of the cross cone and the cross groove allows the user to easily push open the cap sealing bottom; the push-open support column can expand the opening of the cap sealing bottom, thereby accelerating the falling of solid materials.

[0004] The above-mentioned prior art presses the hopper downwards, and the hopper is deformed by force, driving the hopper force column downwards. The hopper force column drives the cross cone to contact the cross groove on the sealing bottom of the cover body, thereby pushing open the middle area of the sealing bottom of the cover body. At the same time, the support column for opening will also push the sealing bottom of the cover body downwards, thereby expanding the opening of the sealing bottom of the cover body and accelerating the falling of solid materials. However, this design has some shortcomings. First, there is only one cross-groove on the sealing bottom of the cover body that is easy to open, which requires more force when pressing and is not convenient to use. Secondly, it is not easy for the support column to completely open the sealing bottom of the cover body in actual operation. Even if it is successfully opened, only a smaller opening will be formed, which can easily cause solid materials to get stuck at the opening and cannot be fully integrated into the liquid in the bottle. In view of this, we propose a solid-liquid separation combined bottle cap structure that can be opened by pressing the sealing bottom to be equally divided. Utility Model Content

[0005] The purpose of the utility model is to provide a solid-liquid separation combined bottle cap structure with a sealed bottom that can be opened by pressing down, so as to solve the problems raised in the above-mentioned background technology.

The surface of the sealing plate is provided with a plurality of strip-shaped easy-to-open positions arranged in a ring array. The tip of the piercing cross cone passes through the barrel and is close to the bottom end of the concave surface of the sealing plate. When the top of the soft cover is pressed and forced to move downward, the piercing cross cone and the piercing circular tube are driven to move downward synchronously. The tip of the piercing cross cone first pierces the central opening position, and the arc-shaped fracture is disconnected from the inside to the outside. The piercing circular tube continues to move downward, opening the strip-shaped easy-to-open position. The sealing plate is subjected to a force from the inside to the outside, and the sealing plate is equally divided and fan-shaped outward, thereby expanding a large discharge port, so that the powdered or granular solid beverage in the barrel can fall into the water bottle, avoiding the problem of material jamming.

[0008] Preferably, an outer cover is provided on the outer side of the sealing cover to protect the soft cover from being pressed by external force and to protect the bottle cap from being accidentally pierced through the cross cone and causing leakage. A plurality of positioning vertical bars arranged in a circular array are provided on the side of the inner wall of the outer cover, and a retaining tooth is provided on the top of the positioning vertical bar. The bottom of the retaining tooth abuts against the top of the edge positioning ring to limit the position and prevent the outer cover from moving downward.

When the sealing cover is unscrewed, the plurality of connecting bridges will break.

[0010] Preferably, a sealing outer seal is provided on the top of the inner wall of the sealing cap, which is used to tightly fit the outer side of the bottle mouth and the sealing outer seal after being installed on the water bottle, so that air or pollutants outside the bottle cannot enter the bottle, thereby playing a sealing role. A sealing inner seal is provided on the middle and upper part of the outer wall of the barrel, which is used to tightly fit the inner side of the bottle mouth and the sealing inner seal after being installed on the water bottle, so that water in the bottle cannot flow out of the cap, thereby playing a sealing role.

[0011] Preferably, the plurality of strip-shaped easy-opening positions are all connected to the arc-shaped fracture, and the number of the strip-shaped easy-opening positions is 4-6. The equally divided top opening method has a large opening area, and the material in the bottle cap is easier to fall into the water bottle without forming a stuck material at the opening, and can be better dissolved in the water in the bottle for drinking.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This push-to-open, sealed, and equally divided solid-liquid separation cap structure, through the design of a push-to-open soft cap and sealing sheet, allows users to achieve solid-liquid separation with just a simple press. The clever combination of a top-penetrating cross cone, a top-penetrating circular tube, a center opening, an arc-shaped fracture, and a strip-shaped easy-opening area makes the opening process smooth and effortless, reducing the force required to press and significantly improving the user experience.

[0017] 2. This push-to-open, sealed, and equally divided solid-liquid separation cap features multiple strip-shaped easy-opening areas that connect to arc-shaped fractures. When the cross-cone and circular tube move downward simultaneously, the sealing strips fan outward in equal sections, forming a larger discharge port.

[0028] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0029] The press-down top-open sealed bottom equally-divided opening type solid-liquid separation combined bottle cap structure comprises a sealing cap 1, the side surface of the inner wall of the sealing cap 1 is provided with an inner screw thread 10, which is used to be installed and tightened with the bottle mouth screw thread, and the top of the sealing cap 1 is provided with a press-down soft cap 2, which is made of elastic material, and the middle part of the top of the inner wall of the press-down soft cap 2 is provided with a top-penetrating cross cone 22, and the outer side of the top-penetrating cross cone 22 is provided with a top-penetrating circular tube 23, and the bottom end of the top-penetrating cross cone 22 protrudes from the bottom of the top-penetrating circular tube 23 to ensure that the tip of the top-penetrating cross cone 22 first penetrates the sealing piece 4, and a barrel 3 is provided through the top of the inner wall of the sealing cap 1, and a sealing piece 4 is provided at the bottom of the barrel 3. The press-down soft cap 2, the barrel 3 and the sealing piece 4 form a storage cavity for storing materials, and the outer surface of the sealing piece 4 is a conical structure, and the bottom end of the sealing piece 4 is provided with a central opening position 40, and the outer edge of the central opening position 40 is provided with a central opening position 40. It is provided with an arc-shaped fracture opening 41, and the surface of the sealing piece 4 is provided with multiple strip-shaped easy-opening positions 42 arranged in a circular array. The multiple strip-shaped easy-opening positions 42 cooperate with the arc-shaped fracture opening 41 to make it easier for the user to penetrate the sealing piece 4. The tip of the piercing cross cone 22 passes through the barrel 3 and is close to the bottom end of the concave surface of the sealing piece 4. When the top of the soft cover 2 is pressed and forced to move downward, the piercing cross cone 22 and the piercing circular tube 23 are driven to move downward synchronously. The tip of the piercing cross cone 22 first penetrates the central opening position 40, and the arc-shaped fracture opening 41 is broken from the inside to the outside. The piercing circular tube 23 continues to move downward, stretching the strip-shaped easy-opening position 42. The sealing piece 4 is subjected to the stretching force from the inside to the outside, and the sealing piece 4 is equally divided and opened outward in a fan shape, thereby expanding a large discharge port, so that the powdered or granular solid beverage in the barrel 3 can fall into the water bottle, avoiding the problem of material jamming.

[0030] In this embodiment, an outer cover 6 is provided on the outer side of the sealing cover 1 to protect the soft cover 2 from being pressed, and to protect the bottle cap from being pressed by external force and accidentally piercing the sealing sheet 4 by the cross cone 22 to cause leakage. A plurality of positioning vertical bars 60 arranged in a circular array are provided on the side of the inner wall of the outer cover 6, and a retaining tooth 61 is provided on the top of the positioning vertical bar 60. The bottom of the retaining tooth 61 abuts against the top of the edge positioning ring 13 to play a limiting role to prevent the outer cover 6 from moving downward. A plurality of positioning vertical grooves 14 arranged in a circular array are provided on the outer wall of the sealing cover 1.

[0031] Specifically, an anti-theft ring 7 is provided at the bottom of the sealing cover 1, and a plurality of card blocks 70 are provided on the inner wall of the anti-theft ring 7. The anti-theft ring 7 is connected to the bottle mouth, which is convenient for the user to confirm whether the sealing cover 1 is in an unopened state to ensure safety. A plurality of connecting bridges 71 are provided at the top of the anti-theft ring 7, and the top of the connecting bridge 71 is fixedly connected to the bottom of the sealing cover 1. When the sealing cover 1 is unscrewed, the plurality of connecting bridges 71 will break.

[0032] Furthermore, a sealing outer seal 11 is provided on the top of the inner wall of the sealing cap 1. After the sealing cap is installed on the water bottle, the outer side of the bottle mouth is tightly fastened with the sealing outer seal 11, so that air or pollutants outside the bottle cannot enter the bottle, thereby playing a sealing role. A sealing inner seal 30 is provided on the middle and upper part of the outer wall of the barrel 3. After the sealing cap is installed on the water bottle, the inner side of the bottle mouth is tightly fastened with the sealing inner seal 30, so that the water in the bottle does not flow out of the cap, thereby playing a sealing role.

[0033] Furthermore, multiple strip-shaped easy-opening positions 42 are connected to the arc-shaped fracture 41, and the number of the strip-shaped easy-opening positions 42 is 4-6. The equally divided top opening method has a large opening area, and the material in the bottle cap is easier to fall into the water bottle, and will not form a stuck material at the opening, and can be better dissolved in the water in the bottle for drinking.

[0034] Furthermore, a deformation position 5 is provided between the bottom of the outer side of the barrel 3 and the top of the outer side of the sealing sheet 4 to ensure that the sealing sheet 4 can be deformed and opened outward.

[0035] Furthermore, a cover edge 20 is provided at the edge of the pressing soft cover 2, and an edge positioning ring 13 is provided at the edge of the top of the sealing cover 1. The outer wall of the cover edge 20 fits with the inner wall of the edge positioning ring 13, so that the cover edge 20 is fixed and does not shift during installation, and the pressing soft cover 2 and the sealing cover 1 maintain an overall beautiful appearance after welding.

[0036] Furthermore, a welding ring 21 is provided at the bottom of the cover edge 20, and a welding groove 12 is provided at the top of the sealing cover 1. The welding ring 21 is welded in the welding groove 12. The welding groove 12 is a concave ring groove. When ultrasonic welding is used, the welding ring 21 melts in the welding groove 12, so that the soft cover 2 and the sealing cover 1 are welded and sealed into one.

[0037] When using the press-down-open sealed bottom equally-divided opening type solid-liquid separation combined bottle cap structure of this embodiment, the user first removes the outer cover 6 from the sealing cover 1, and then presses the top of the pressing soft cover 2 with a finger. Since the pressing soft cover 2 is made of elastic material, it can move downward after being subjected to force. When pressing the soft cover 2, the tip of the cross cone 22 will first contact and penetrate the central opening position 40 of the sealing plate 4, and the arc-shaped fracture 41 will be broken from the inside to the outside. Continue to press the top of the pressing soft cover 2, and the penetrating circular tube 23 will move downward synchronously, further stretching the multiple strip-shaped easy-opening positions 42, so that the sealing plate 4 is opened outward in equal parts to form a large fan-shaped opening. Through the pressing operation, the solid material in the bottle cap, such as powdered or granular solid beverage, will smoothly fall into the liquid in the bottle through the opened sealing plate 4, ensuring that all solid materials fall into the bottle smoothly and are not stuck at the opening. After the solid materials fall into the liquid, the bottle body can be shaken or stirred to fully mix the solid materials with the liquid in the bottle to achieve an ideal mixing effect.
