Description

Technical Field

[0001] This invention relates to the field of liquid packaging, and more particularly to a wing-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 plate-like structure, which does not require the pressurized container to be fixed in place. During use, the plate-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 plate-like structure and presses down on the pressurized container to release the internal liquid. Because the drive component and the pressurized container are not fixed in this type of device, during use, the drive component and the pressurized container only have contact with the top surface of the valve stem. The contact surface is unstable, making it easy for the container to shake and slip off.

[0004] Another form requires assembling and fixing the pressurized container tank with an auxiliary drive device. The auxiliary drive device is made into a long cylindrical shell with a smooth cylindrical outer surface, 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 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, and the internal liquid is ejected outward through a small hole in the center of the bottom plane. This type of enclosed drive shell fixes the auxiliary drive device and pressurized container tank in place, preventing the container from shaking during use. However, because the entire outer shell is a smooth cylinder, it does not solve the problem of device slippage. Summary of the Invention

[0005] The main objective of this invention is to provide a pressurized liquid-assisted drive device that is stable and does not easily slip, in response to the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wing-type pressurized liquid-assisted 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 cylindrical structure and is sleeved on the aerosol valve outlet end of the pressurized container tank, and two supporting wings extend outward in the horizontal direction from the opening of the auxiliary drive housing.

[0007] Preferably, the two support wings are arranged symmetrically.

[0008] Furthermore, the support wing is arc-shaped, with the arc-shaped protruding end facing the opening side of the auxiliary drive housing.

[0009] Preferably, a reinforcing rib is provided between the supporting wing and the cylindrical structure of the auxiliary drive housing.

[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 extends two support wings in the horizontal direction. The support wings are symmetrically distributed. During use, the user holds the support wings and the bottom of the pressurized container in their hand to make the whole device more balanced and avoid the pressurized container shaking due to uneven force during use, thus ensuring the stability of the device during use.

[0016] 2. The auxiliary drive housing retains a partially cylindrical structure, allowing the housing to be assembled and fixed with the pressurized container tank. This ensures stable operation during use while maintaining the simplicity and lightness of the device.

[0017] 3. The symmetrical double-wing structure gives the user greater control over the overall device, which is beneficial for controlling the liquid discharge direction and the force application process. Attached Figure Description

[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 4 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 by an aerosol valve. The liquid inside the pressurized container 1 can be released by pressing the valve stem of the aerosol valve. Two support wings 3 extend horizontally outward from the opening of the auxiliary drive housing 2. The support wings 3 are arc-shaped, and the arc-shaped protruding ends face the opening side of the auxiliary drive housing 2. During use, the pressurized container 1 and the auxiliary drive housing 2 are installed and fixed together. The user uses the support wings 3 and the bottom of the pressurized container 1 to hold the entire device in their hand, and then applies force to press the pressurized container 1 to drive the aerosol valve.

[0027] like Figure 3 As shown, the auxiliary drive housing 2 has symmetrically arranged support wings 3 at both ends. The user can place any finger against the support wing 3 for easy control of the overall device and application of force. A reinforcing rib 6 is provided between the support wing 3 and the cylindrical part of the auxiliary drive housing 2. In the preferred embodiment, a single reinforcing rib 6 is used corresponding to a single support wing 3 as shown in the figure. However, the form of the reinforcing rib 6 should not be limited to the example shown in the figure. It can also be multiple reinforcing ribs 6 corresponding to a single support wing 3, or the reinforcing rib 6 can be widened to the same width as the support wing 3, or the reinforcing rib 6 can be changed to an irregular shape, etc.

[0028] like Figure 4As shown, the auxiliary drive housing 2 has a slanted liquid outlet 4 extending outward from the center of its bottom. Based on the extension position of the outlet 4, the user can clearly see the expected direction of the liquid spray, making the device easier to use. Simultaneously, the slanted design ensures that the outlet 4 has a certain piercing function. When the user needs to use this device on sealed containers such as Tetra Pak cartons, the outlet 5 can be used to pierce the plastic seal of the container, making overall use faster and more convenient. An annular limiting step 5 is provided at the center of the auxiliary drive housing 2. When the pressurized container tank 1 is assembled and fixed with the auxiliary drive housing 2, the limiting step 5 will surround the valve stem of the pressurized container tank 1, preventing the valve stem of the pressurized container tank 1 from shaking during use.

[0029] 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.
