Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to spray cans and more particularly, to an auxiliary clamping operation device for spray can.

2. Description of the Related Art

A spray can generally comprises a pressure can and a valve located on the top side of the pressure can. When the valve is opened, the contents of the pressure can are released in a mist. Therefore, it is suitable for all kinds of medical and health products, cosmetics, household cleaning and maintenance products and industrial supplies. The valve is usually equipped with a button that can be pressed by the user. The button may be slightly leaked after a long use, and the user may directly contact the contents ejected from the pressure can during the pressing of the button, causing inconvenience in use, and even affecting the health of the body.

At present, there is a sprayer for assisting the holding of a spray can. The sprayer can be directly assembled in a spray can, so that the user can hold and operate the spray can, preventing dropping of the spray can or user contamination by the contents of the spray can.

However, the operation of the existing sprayer for spray can is still relatively laborious, and there are many components, and the assembly procedure is complicated, resulting in high overall assembly cost.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide an auxiliary clamping operation device for spray can, which simplifies the overall composition and assembly steps, and saves effort and extends service life and quality.

To achieve this and other objects of the present invention, an auxiliary clamping operation device includes a grip. The grip includes two clamping parts disposed at one end thereof, and a receiving space defined between the two clamping parts. Each clamping part has a triggering portion and a positioning portion disposed on opposite sides. The two trigger portions are fastened together so that the two positioning portions are drivable by the trigger portions to move between an open position where the spray can is separable from the clamping parts, and a close position where the clamping parts clamp the spray can.

Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.

DETAILED DESCRIPTION OF THE INVENTION

The technical content and features of the present invention are described hereinafter with reference to the annexed drawings. The present invention can be widely applied to spray cans of various forms or specifications. Those skilled in the art can understand that the explanatory terms of the present preferred embodiment belong to a generic description that does not limit the application. For example, a material or shape term includes, without limitation, the material or shape specified by the description, and the positional terms include and are not limited to setting, approaching, connecting, or abutting. The quantity “a” of each component includes the number of one or more components. The directional expressions such as “upper”, “lower”, “inside”, “outside”, “top” and “bottom” mentioned in the contents of this specification are merely illustrative terms used in the normal direction of use, not intended to limit the meaning of the claim.

Referring to FIGS. 1-5, an auxiliary clamping operation device for spray can in accordance with a first embodiment of the present invention includes a grip 10 consisting of two half shells 12. Each half shell 12 is made of plastic material, so that each half shell 12 can have a small amount of deformation. The top of the grip 10 is formed with two clamping parts 20, and a receiving space 14 is formed between the two clamping parts 20 for receiving the top of a spray can 30. A discharge port 16 is defined between the two clamping parts 20 and disposed in communication with the receiving space 14 such that the discharge port 16 corresponds to the valve 32 of the spray can 30. The two clamping parts 20 respectively have a triggering portion 22 and a positioning portion 24 disposed on opposite sides of each other. The two trigger portions 22 are abutted to each other and fixed together by a fastening member 26. In this embodiment, the fastening member 26 is a screw. After the two trigger portions 22 are fixed together, the two positioning portions 24 can be driven by the two trigger portions 22 to move between an open position (as shown in FIG. 7) or a close position (as shown in FIG. 6). When the positioning portions 24 are in the open position, the spray can 30 can be separated from the clamping parts 20. When the positioning portions 24 are in the close position, the clamping parts 20 can clamp the spray can 30.

The grip 10 further includes a pressing member 40 having an operating portion 42 and a pressing portion 44. The pressing member 40 is pivoted inside the grip 10. The operating portion 42 extends to the outside of the grip 10. Further, the pressing portion 44 is disposed within the receiving space 14 above the valve 32 of the spray can 30. The user can hook the operating portion 42 while holding the grip 10 and let the pressing portion 44 act upon the valve 32 of the spray can 30.

By using the above-mentioned constituent members, the two clamping parts 20 for positioning the spray can 30 can be combined with each other by using only the fastening member 26, and no additional components are required. After the trigger portions 22 are pressed, the positioning portions 24 can be controlled to secure or release the spray can 30 stably. The auxiliary clamping operation device is convenient to use, simplifies the overall composition and assembly steps, and saves labor, thereby prolonging the service life and quality of use.

In order to reinforce the structural strength and positioning function between the two clamping portions, the fastening member 26 can be further provided with a washer and then fixed to affix the two trigger portions 22. Thus, in addition to increasing the bonding strength of the two trigger portions 22, the positioning force between the two positioning portions 24 can be enhanced, and the spray can can be secured more firmly.

Referring to FIGS. 8-10, an auxiliary clamping operation device for spray can in accordance with a second embodiment of the present invention is shown. The constituent members of this second embodiment are the same as the first preferred embodiment. The main feature is that the fastening member 50 comprises a spring 52 and two pins 54 are placed at each end of the spring 52, the fastening member 50 is provided between the trigger portions 22, so that the two trigger portions 22 can also abut each other and be fixed together, and the two positioning portions 24 can also be driven by the two trigger portions 22 to move between an open position (see FIG. 10) or a close position (see FIG. 9).
