Description

Technical Field

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

[0002] Traditional beverage bottles typically contain pre-mixed ingredients, with two or more materials combined during production. Prolonged interaction between these ingredients can negatively impact the beverage's effectiveness and shorten its shelf life. Therefore, bottle caps with storage chambers were invented. Concentrates, tea powder, honey, or other soluble substances are stored in these chambers. When ready to drink, the bottom of the chamber is opened, allowing the soluble substances to flow into or fall into the bottle, where they mix to form the desired beverage. For example, Chinese Patent No. 201921035920.1 describes a soluble inner core bottle cap and beverage bottle. Its specific structure includes an inner core, a main cap, and a pressing component. The pressing component is installed above the main cap, and the inner core is installed inside the main cap. The main cap seals the bottle opening and provides support for the inner core and the pressing component. The inner core contains a holding component for holding solute materials. The holding component is a circular tube with a through hole, allowing the solute materials to be placed inside the through hole. The pressing component is a pressure cap. An anti-theft cap is installed at the top of the pressing component, allowing it to be pressed down only after it is opened. In this structure, the connection between the inner core and the main cap has a poor sealing effect, making it easy for the solute inside the inner core to leak. Simultaneously, during the sterilization process, disinfectant can easily enter the inner core, contaminating the solute materials. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a press-type ready-to-use bottle cap with good sealing performance.

[0004] The objective of this utility model can be achieved through the following technical solution: A press-type ready-to-use bottle cap includes a bottle neck cap, a storage bin, a press cap, and an outer end cap. The bottle neck cap includes an outer shell and an inner shell. The outer shell is threaded onto the bottle neck. The storage bin is located inside the inner shell. The bottom of the storage bin has several discharge holes. The bottom of the storage bin is sealed to the inner shell through a sealing ring. The press cap is sealed and installed at the opening at the top of the storage bin. Pressing down the press cap moves the storage bin downward until the discharge holes expose the inner shell. The outer end cap is fitted onto the press cap. The bottom of the outer end cap protrudes downward to form a first insertion ring. The outer circumferential surface of the first insertion ring is in close contact with the inner circumferential surface of the top of the bottle neck cap.

[0005] In the aforementioned press-type ready-to-use bottle cap, the sealing ring is fitted onto the outer wall of the storage hopper. The sealing ring has two first sealing protrusions, which are in close contact with the inner wall of the inner shell. The two first sealing protrusions are located above and below the discharge hole, respectively. The outer wall of the storage hopper also has an installation groove, and the sealing ring is located in the installation groove.

[0006] In the aforementioned press-type ready-to-use bottle cap, the bottom of the storage compartment is provided with a positioning flange, the bottom of the inner shell is in contact with the top surface of the positioning flange, the bottom of the storage compartment is also provided with a mounting hole that penetrates the positioning flange, the bottom of the sealing ring is connected to a sealing protrusion by a connecting strip, the sealing protrusion is inserted into the mounting hole, and the bottom of the inner shell contacts the sealing protrusion in the mounting hole.

[0007] In the aforementioned press-type ready-to-use bottle cap, the bottom of the press cap is provided with a second insertion ring, the outer circumferential surface of the second insertion ring is provided with a second sealing protrusion, the inner circumferential surface of the top of the storage bin is provided with a sealing groove, the second insertion ring is inserted into the storage bin, the second sealing protrusion is engaged in the sealing groove, and the bottom of the second insertion ring is also provided with a guide slope.

[0008] In the aforementioned press-type ready-to-use bottle cap, the center of the press cap protrudes and forms a step with the second insertion ring. After the second insertion ring is inserted into the storage bin, the top of the storage bin contacts the step. During the pressing process, when the step contacts the top surface of the inner shell, the press cap stops moving downward.

[0009] In the aforementioned press-type ready-to-use bottle cap, a first anti-theft ring is fitted on the top of the bottle cap, and the outer end cap is connected to the first anti-theft ring by a plurality of first connecting bridges.

[0010] In the aforementioned push-button ready-to-use bottle cap, a second anti-theft ring is also fitted on the bottle opening. The second anti-theft ring is located below the outer shell and is connected to the outer shell through several second connecting bridges.

[0011] Compared with existing technologies, this press-type ready-to-use bottle cap offers a simple and quick dispensing and opening process, making it convenient to operate. The outer circumference of the insertion ring is tightly fitted to the inner circumference of the top of the bottle cap, thus sealing the connection between the bottom of the outer cap and the bottle cap, preventing disinfectant from entering the bottle cap, ensuring the dryness of the inside of the bottle cap, and maintaining the quality of the solute in the storage compartment, resulting in a good sealing effect. The first sealing ring is tightly fitted to the inner wall of the inner shell, achieving a seal between the dispensing hole and the inner shell. The first sealing ring located below the dispensing hole prevents the solute in the storage compartment from accidentally leaking into the bottle body through the dispensing hole, thus preventing premature mixing with the solvent and causing solvent deterioration. The first sealing ring located above the dispensing hole prevents the solute in the storage compartment from accidentally leaking to the outside through the dispensing hole, contaminating the bottle cap and other components, and reducing the amount of solute in the storage compartment. The second sealing ring is engaged in the sealing groove, achieving a sealed installation between the press cap and the storage compartment, preventing the press cap from falling off the storage compartment, and also preventing the solute stored in the storage compartment from leaking out from the top opening of the storage compartment.

Detailed Implementation

[0016] 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.

[0017] like Figure 1-3As shown, this push-button ready-to-use bottle cap includes a bottle neck cap 1, a storage compartment 2, a push-button cap 3, and an outer end cap 4. The bottle neck cap 1 includes an outer shell 11 and an inner shell 12. The outer shell 11 is threaded onto the bottle neck 7. The storage compartment 2 is located inside the inner shell 12, and its bottom has several discharge holes 21. The bottom of the storage compartment 2 is sealed to the inner shell 12 by a sealing ring 6. The push-button cap 3 is sealed to the opening at the top of the storage compartment 2. Pressing down the push-button cap 3 moves the storage compartment 2 downwards until the discharge holes 21 are exposed above the inner shell 12. The outer end cap 4 is fitted onto the push-button cap 3. A first anti-theft ring 5 is fitted onto the top of the bottle neck cap 1, and the outer end cap 4 is connected to the first anti-theft ring 5 by several first connecting bridges 51. The first anti-theft ring 5 and the first connecting bridges 51 prevent the outer end cap 4 from being accidentally opened, thus preventing the push-button cap 3 from being damaged and unprotected. The bottom of the outer end cap 4 protrudes downward to form a first insertion ring 41, and the outer circumferential surface of the first insertion ring 41 is in close contact with the inner circumferential surface of the top of the bottle cap 1. Because there are gaps between the several first connecting bridges 51 or between the bottom of the outer end cap 4 and the bottle cap 1, during the bottle cap disinfection and cleaning process, disinfectant can enter the bottle cap 1 through these gaps. The entry of disinfectant can easily cause mold growth inside the bottle cap 1 and contaminate the solute in the storage bin 2. Therefore, this invention provides a first insertion ring 41, and ensures that the outer circumferential surface of the first insertion ring 41 is in close contact with the inner circumferential surface of the top of the bottle cap 1, thereby sealing the connection between the bottom of the outer end cap 4 and the bottle cap 1, preventing disinfectant from entering the bottle cap 1, ensuring the dryness of the inside of the bottle cap 1, and guaranteeing the quality of the solute in the storage bin 2.

[0018] In the above technical solution: the sealing ring 6 is sleeved on the outer wall of the storage bin 2, and two first sealing protrusions 61 are formed on the sealing ring 6. The first sealing protrusions 61 are in close contact with the inner wall of the inner shell 12, and the two first sealing protrusions 61 are respectively located above and below the discharge hole 21. The outer wall of the storage bin 2 is also formed with an installation groove 22, and the sealing ring 6 is located in the installation groove 22 to achieve embedded installation.

[0019] In the above technical solution: a positioning flange 23 is formed at the bottom of the storage bin 2, and the bottom of the inner shell 12 contacts the top surface of the positioning flange 23. A mounting hole 24 penetrating the positioning flange 23 is also formed at the bottom of the storage bin 2. A sealing protrusion 63 is connected to the bottom of the sealing ring 6 via a connecting strip 62. The sealing protrusion 63 is inserted into the mounting hole 24, and the bottom of the inner shell 12 contacts the sealing protrusion 63 within the mounting hole 24.

[0020] In the above technical solution: a second insertion ring 31 is provided at the bottom of the pressing cover 3, and a second sealing protrusion 32 is formed on the outer peripheral surface of the second insertion ring 31. A sealing groove 25 is formed on the inner peripheral surface of the top of the storage bin 2. The second insertion ring 31 is inserted into the storage bin 2, and the second sealing protrusion 32 is engaged in the sealing groove 25, thereby achieving a sealed installation between the pressing cover 3 and the storage bin 2, preventing the pressing cover 3 from falling off the storage bin 2, and also preventing the solute stored in the storage bin 2 from leaking out from the top opening of the storage bin 2. A guide slope 33 is also formed at the bottom of the second insertion ring 31, which guides the process of the second insertion ring 31 being inserted into the storage bin 2.

[0021] In the above technical solution: the middle part of the pressing cover 3 protrudes and forms a step 34 between it and the second insertion ring 31. After the second insertion ring 31 is inserted into the storage bin 2, the top of the storage bin 2 contacts the step 34. During the pressing of the pressing cover 3, when the step 34 contacts the top surface of the inner shell 12, the pressing cover 3 stops moving downward; the step 34 limits the downward movement of the pressing cover 3 and the storage bin 2, preventing the storage bin 2 from detaching from the inner shell 12.

[0022] In the above technical solution: a second anti-theft ring 8 is also fitted on the bottle mouth 7. The second anti-theft ring 8 is located below the outer shell 11 and is connected to the outer shell 11 through several second connecting bridges 81. The second anti-theft ring 8 and the second connecting bridges 81 protect the bottle mouth 7 from opening, prevent the outer shell 11 from accidentally rotating relative to the bottle mouth 7, prevent the bottle mouth 7 from accidentally opening, and ensure that the solvent inside the bottle is not contaminated.

[0023] When the press-type ready-to-drink bottle cap needs to be dispensed, rotate the outer end cap 4 to break the first connecting bridge 51, then remove the outer end cap 4 from the press cap 3, press down the press cap 3, and the press cap 3 will move the storage bin 2 down synchronously until the dispensing hole 21 is exposed in the inner shell 12. The solute in the storage bin 2 mixes with the solvent in the bottle through the dispensing hole 21. After shaking the bottle to fully mix the solvent and solute, rotate the outer shell 11, the second connecting bridge 81 breaks, the bottle mouth 7 is opened, and it is ready to drink.

[0024] The press-type ready-to-use bottle cap is very simple and quick to dispense and open, making it easy to operate. The outer circumference of the first insertion ring 41 is tightly attached to the inner circumference of the top of the bottle cap 1, thereby sealing the connection between the bottom of the outer cap 4 and the bottle cap 1, preventing disinfectant from entering the bottle cap 1, ensuring the dryness of the inside of the bottle cap 1, and ensuring the quality of the solute in the storage bin 2, resulting in a good sealing effect. The first sealing protrusion 61 is tightly attached to the inner wall of the inner shell 12, achieving a seal between the dispensing hole 21 and the inner shell 12. The first sealing protrusion 61 located below the dispensing hole 21 prevents the storage of liquid from entering the bottle cap 1. The solute in the storage chamber 2 may accidentally leak into the bottle body through the discharge hole 21, causing it to mix with the solvent prematurely and deteriorate. The first sealing ring 61 located above the discharge hole 21 prevents the solute in the storage chamber 2 from accidentally leaking to the outside through the discharge hole 21, contaminating the bottle cap 1 and other components, and also reducing the amount of solute in the storage chamber 2. The second sealing ring 32 is inserted into the sealing groove 25 to achieve a sealed installation between the press cap 3 and the storage chamber 2, preventing the press cap 3 from falling off the storage chamber 2 and also preventing the solute stored in the storage chamber 2 from leaking out from the top opening of the storage chamber 2.
