Description

Technical Field

[0001] This invention relates to the field of liquid packaging, and more particularly to a grip-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 and the point of force application are too far apart, this type of sheet-like structure is prone to cracking or even breaking after use, and cannot meet the needs of repeated use.

[0004] Another form requires assembling and securing the pressurized container with an auxiliary drive device. The auxiliary drive device is made into a cylindrical shell, enclosing the pressurized container within the shell, leaving only the top surface open for pressing. During use, the user holds the cylindrical shell and presses down on the pressurized container through the open top surface, causing the valve stem at the container's opening to press against the bottom plane of the shell. The liquid inside 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 user's grip and application of force. Summary of the Invention

[0005] The main objective of this invention is to provide a pressurized liquid-assisted drive device that is easy to use and less prone to slippage, addressing the aforementioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a grip-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 auxiliary drive housing has a semi-open structure and can be fitted onto the inverted pressurized container tank; a hanging arm is provided at the upper end of the auxiliary drive housing, and a support edge extends from the bottom end on the same side of the hanging arm.

[0007] Furthermore, the vertical distance from the highest point of the lower end face of the hanging arm to the upper end face of the support is 20-80mm.

[0008] Preferably, the vertical distance from the highest point of the lower end face of the hanging arm to the upper end face of the support is 65-75mm.

[0009] Preferably, the hanging arm is curved.

[0010] Furthermore, the auxiliary drive housing has a liquid outlet extending outward from the center of its bottom end.

[0011] Preferably, the bottom end of the liquid outlet is inclined.

[0012] Furthermore, a limiting step is provided at the center of the interior of the auxiliary drive housing.

[0013] Preferably, the auxiliary drive housing is integrally injection molded.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The auxiliary drive housing is designed with a hanging arm and a support edge at the same end, so that when the user applies downward force, the hanging arm can hook the upper edge of the user's hand to prevent the device from slipping during use, and also make it easier for the user to apply force.

[0016] 2. An obliquely shaped liquid outlet is added to the bottom of the auxiliary drive housing, which can integrate the function of piercing the plastic seal of Tetra Pak packaging, thus broadening the application scenarios of the device and making the liquid outlet direction of the device more visible, making it more convenient and practical.

[0024] 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.

[0025] Figures 1 to 5 A preferred embodiment of this pressurized liquid-assisted drive device of the present invention is shown. Wherein:

[0026] like Figure 1-2 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.

[0027] like Figure 3-4 As shown, the upper end of the auxiliary drive housing 2 is provided with a hanging arm 3. The hanging arm 3 extends horizontally outward relative to the auxiliary drive housing 2, and is preferably curved to better fit the shape of the user's hand and optimize the user experience. On the same side as the hanging arm 3, the bottom end of the auxiliary drive housing 2 extends horizontally outward with a support edge 4. Using the support edge 4, the user can lean the entire pressurized liquid auxiliary drive device against the mouth of a cup or bottle to assist the user in completing the force application action.

[0028] The auxiliary drive housing 2 has a slanted liquid outlet 5 extending outward from the center of its bottom. The slanted outlet 5 allows the user to clearly see the expected direction of the liquid spray, making the device easier to use. The slanted design also ensures that the outlet 5 has a piercing function. When using this device on sealed containers such as Tetra Pak cartons, the outlet 5 can be used to pierce the plastic seal, making overall use faster and more convenient. An annular limiting step 6 is located at the center of the auxiliary drive housing 2. After the pressurized container 1 and the auxiliary drive housing 2 are assembled and fixed together, the limiting step 6 surrounds the valve stem of the pressurized container 1, preventing the valve stem of the pressurized container 1 from shaking during use.

[0029] like Figure 5As shown, the center of the limiting step 6 and the liquid outlet 5 is set as a through hole structure, so that the liquid inside the pressurized container tank 1 can be discharged smoothly. The vertical distance from the highest point of the lower end face of the hanging arm 3 to the upper end face of the support edge 4 is preferably 65-75mm, which can be accommodated by about four fingers of the user, making it convenient for the user to hold.

[0030] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," indicating orientation or positional relationships, are merely for the convenience of simplifying the description of this invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention.
