Description

Technical Field

[0001] This invention relates to the field of liquid packaging, and more particularly to a ring-type pressurized liquid auxiliary drive device. Background Technology

[0002] Pressurized liquids commonly found on the market are often stored in cans sealed with aerosol valves. The liquid stored inside can be released by squeezing the valve stem protruding from the can opening from the outside. This technology is now gradually being used in the packaging of coffee or tea drinks, making it easier for users to dispense the desired concentrate.

[0003] However, existing auxiliary drive devices for pressurized containers mostly fall into two categories, both of which have shortcomings. One type is a sheet-like structure, which does not require the pressurized container to be fixed in place. During use, the sheet-like structure is placed on the mouth of a cup or bottle, and the user aligns the valve stem of the pressurized container's opening with the small hole in the center of the sheet-like structure and presses down on the pressurized container to release the internal liquid. However, because the placement position of this type of sheet-like structure is too far from the point of force application, it is prone to cracking or even breaking after use. Furthermore, since this type of sheet-like structure is not fixed to the pressurized container, if the user applies force at an angle, the pressurized container may misalign or slip off from the small hole on the sheet-like structure.

[0004] Another form requires assembling and fixing the pressurized container tank with an auxiliary drive device. The auxiliary drive device is made into a cylindrical shell, enclosing the pressurized container tank within the shell, leaving only the top surface open for pressing. During use, the user holds the cylindrical shell and presses the internal pressurized container tank through the open top surface, causing the valve stem at the container opening to press against the bottom plane of the shell. The internal liquid is then ejected outwards through a small hole in the center of the bottom plane. This form solves the force-bearing problem of the device and is more convenient and secure. However, because the shell is cylindrical, it is prone to slipping during the gripping and applying force, making it difficult to apply pressure. Summary of the Invention

[0005] The main objective of this invention is to provide a pressurized liquid-assisted drive device that facilitates the application of force by the user, addressing the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a ring-type pressurized liquid auxiliary drive device, comprising a pressurized container tank and an auxiliary drive housing, wherein the pressurized container tank stores liquid and pressurized gas inside and is sealed by an aerosol valve; furthermore, the main body of the auxiliary drive housing has a cylindrical structure, the opening of which is used to accommodate the pressurized container tank, and one or more rings are provided on one side of the opening end of the auxiliary drive housing in the vertical direction.

[0007] Furthermore, the bottom plane of the auxiliary drive housing body has a protruding plane extending laterally, and the protruding plane is located below the ring.

[0008] Preferably, a reinforcing rib is provided between the protruding plane and the ring.

[0009] Furthermore, the protruding plane forms an angle of 15° to 60° with the bottom plane of the auxiliary drive housing body. Angle.

[0010] Preferably, the protruding plane forms an angle of 30° to 45° with the bottom plane of the auxiliary drive housing body.

[0011] Furthermore, the auxiliary drive housing has a liquid outlet extending outward from the center of its bottom end.

[0012] Preferably, the bottom end of the liquid outlet is inclined.

[0013] Furthermore, a limiting step is provided at the center of the interior of the auxiliary drive housing.

[0014] Preferably, the auxiliary drive housing is integrally injection molded.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A protruding plane is provided at the bottom of the auxiliary drive housing at a certain angle. During use, the user can place the protruding plane against the edge of the container to be added liquid or on their finger. The protruding plane makes it easier to apply force during use. The widened protruding plane can also prevent the device from shaking or misaligning significantly during use.

[0017] 2. The vertically positioned ring structure can serve as an auxiliary grip structure. Users can improve their control over the device by placing the ring structure on their fingers, while also preventing the hand from slipping off the device when the user applies force.

[0018] 3. The protruding plane is clamped at a certain angle to the bottom of the auxiliary drive housing, so that the liquid outlet path inside the device is not in the shadow directly below the device during use, making it easier for the user to observe the liquid outlet status during use.

[0026] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Figures 1 to 4 A preferred embodiment of this pressurized liquid-assisted drive device of the present invention is shown. Wherein:

[0028] like Figure 1 As shown, the auxiliary drive housing 2 has a semi-open structure, and the pressurized container 1 is installed upside down inside the auxiliary drive housing 2. The pressurized container 1 stores liquid and a special gas. The special gas pressurizes the internal container. The pressurized container 1 is sealed using an aerosol valve. The liquid inside the pressurized container 1 can be released by pressing the valve stem of the aerosol valve. During use, the pressurized container 1 is fixedly installed on the auxiliary drive housing 2. The user holds the container on the auxiliary drive housing 2 and applies pressure to the pressurized container 1 to activate the aerosol valve.

[0029] like Figure 2-4As shown, the auxiliary drive housing 2 has one or more finger rings 3 vertically arranged on one side of the opening end. Below the finger rings 3, there is a protruding plane 4 extending laterally from the bottom plane of the main body of the auxiliary drive housing 2. A reinforcing rib is provided between the protruding plane 4 and the finger rings 3. There is a certain angle between the protruding plane 4 and the bottom plane of the main body of the auxiliary drive housing 2, which can be selected as an angle of 30° to 45°. During use, the user can insert their fingers into the finger rings 3, place the protruding plane 4 between their fingers or at the opening of the container to be added, and press the bottom of the pressurized container 1. The entire device will then tilt to complete the liquid dispensing. An annular limiting step 6 is provided in the center of the auxiliary drive housing 2. When the pressurized container 1 is installed with the auxiliary drive housing 2, the limiting step 6 will fix the aerosol valve on the pressurized container 1, ensuring that the pressurized container 1 will not shake or misalign during use.

[0030] like Figure 5 As shown, a reinforcing rib 7 is provided between the ring 3 and the protruding plane 4 to ensure the strength of the ring 3 during use and prevent deformation of the ring 3 due to excessive force, thereby affecting the force direction of the device. A liquid outlet 5 with a bevel extends outward from the center of the bottom of the auxiliary drive housing 2. Based on the extension position of the liquid outlet 5, the user can clearly see the expected direction of liquid ejection, making the device easier to use. At the same time, the bevel design ensures that the liquid outlet 5 has a certain piercing function. When the user needs to use this device on sealed containers such as Tetra Pak packaging, the liquid outlet 5 can be used to pierce the plastic seal of the container, making overall use faster and more convenient.
