1. Field of the Invention
The present invention relates to a clamping device, and more particularly to a clamping device for a sprayer can.
2. Description of the Prior Art
A sprayer can is composed of a valve, a container and content, and the content is contained in the container to become a pressure container. When the valve is actuated, the content is released through a corresponding controlling method to outside with a predetermined pressure. It is widely used in sanitary articles, cosmetics, cleansing articles and industrial articles.
However, the sprayer can has inconvenience. For example, a button-typed sprayer can is usually leaking near a button after a period of time in using. The content of the sprayer can is a chemical synthetic and harmful to human health so that it is necessary to avoid from contacting with the content directly. But when a user pushes the button and the content is leaking near the button, the user contacts with the content. This is a big risk to a health of the user.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a clamping device for a sprayer can, for preventing from contacting with a sprayer can directly and reducing a risk of harming human health. A clamping portion of the clamping device can fix a circumferential flange of a sprayer can steadily, and a circumferential wall of the clamping portion is designed to easily and conveniently assemble substantially and to have a strong structural strength.
To achieve the above object, a clamping device for a sprayer can in accordance with present invention includes a shell body. The shell body includes a grip portion and a clamping portion for clamping one end of a sprayer can. The sprayer can is provided with a dispenser valve at the end. The clamping portion includes a circumferential wall, and the circumferential wall defines a space for receiving the dispenser valve and a receiving opening communicating with the space. The circumferential wall is further formed with a window which communicates with the space, and the dispenser valve can spray through the window. The circumferential wall includes a plurality of first flexible portions and at least one second flexible portion transverse to the receiving opening and extending to the receiving opening. The at least one second flexible portion is connected between every two adjacent first flexible portions. The second flexible portion is greater than the first flexible portion in flexibility.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment in accordance with the present invention.
Please refer to
The circumferential wall 40 defines a plurality of first flexible portions 80 and at least one second flexible portion 90 transverse to a direction of the receiving opening 60 and extending to the receiving opening 60. Every two adjacent first flexible portions 80 are connected with one said second flexible portion 90 disposed therebetween. The second flexible portion 90 is greater than the first flexible portion 80 in flexibility. For example, the first flexible portion 80 and the shell body 10 can have a same material and be formed integrally to have a strong structure. The second flexible portion 90 disposed between the first flexible portions 80 is such as rubber. Compared with the first flexible portion 80, the second flexible portion 90 has larger flexibility and better restitution capability. Conveniently, the circumferential wall 40 is designed so that the clamping portion 30 and the sprayer can 140 are easy to assemble. Preferably, the first flexible portion 80 provides a clamping force for clamping the sprayer can 140. The second flexible portion 90 provides a restitution force for a plurality of said first flexible portions 80 and increases a structural strength of the clamping portion 30. The clamping portion 30 is hard to deform and damage when it assembles to the sprayer can 140. The design of the circumferential wall 40 is substantially easy and convenient for assembling and has a good structural strength.
Furthermore, the circumferential wall 40 includes a main body formed with the first flexible portions 80. Every two adjacent first flexible portions 80 form a slot 100 therebetween and the slot 100 is transverse to and communicated with the receiving opening 60. The second flexible portion 90 each is disposed in one said slot 100 and connected to the adjacent first flexible portions 80. In the present embodiment, the circumferential wall 40 includes a plurality of said second flexible portions 90. For example, the circumferential wall 40 can be formed through plastic injection molding, and the circumferential wall 40 is formed with a plurality of said first flexible portions 80 and at least one said slot 100 after injection molding. The second flexible portion 90 is assembled to the slot 100 via another process. For example, the second flexible portion 90 can be stuck to the slot 100 via glue or by fritting.
It is noted that the circumferential wall 40 can be formed integrally in one process, and the circumferential wall 40 includes a plurality of said second flexible portions 90. For example, the circumferential wall 40 can be formed through dual injection molding. Practically, a plurality of said first flexible portions 80 are formed via plastic injection molding on an injection molding machine and then a plurality of said second flexible portions 90 are formed via rubber injection molding on the same injection molding machine so that the first and second flexible portions 80, 90 are fritted to each other and formed in only one process.
The circumferential wall 40 further includes a buckle flange 110 surrounding the receiving opening 60. The buckle flange 110 is for fixing with a circumferential flange 142 of the end of the sprayer can 140. Moreover, the buckle flange 110 is a protrusion circumferentially formed inwardly. Preferably, the buckle flange 110 can be formed with a chamfer on an edge, and it is convenient and easy for assembling. The at least one second flexible portion 90 extendedly crosses beyond the buckle flange 110 transversely.
In the present embodiment, the receiving opening 60 is C-shaped. A number of the at least one second flexible portions 90 is two, and the at least one second flexible portion 90 is disposed opposite to an opening of the receiving opening. The second flexible portions 90 are respectively located on different positions so that the receiving opening 60 is divided equidistantly. Preferably, when the clamping portion 30 and the sprayer can 140 are assembled to each other, a clamping force induced between the buckle flange 110 and the circumferential flange 142 of the sprayer can 140 is applied to the circumferential wall 40 averagely, and it is convenient and easy for assembling. Referring to
The shell body 10 is pivoted with an operating member 120. The operating member 120 includes a first end 121 and a second end 122 which are reversely movable simultaneously. The first end 121 corresponds to the dispenser valve 141 when the clamping portion 30 is used to clamp the end of the sprayer can 140, and when the second end 122 of the operating member 120 is actuated, the first end 121 actuates the dispenser valve 141 to spray. For example, the operating member 120 can be formed with a through hole 123 correspond to the shell body 10. The shell body 10 is disposed with an axle bolt 13 for the through hole 123 of the operating member 120 to sleeve thereto. The operating member 120 is rotatable about the axle bolt 13. Preferably, the second end 122 is located adjacent to the grip portion 20, and the second end 122 is conveniently actuated by hand. It is noted that the operating member 120 further includes an assisting portion 124. The assisting portion 124 is assembled to and stuck with the shell body 10. When the second end 122 is actuated, the assisting portion 124 provides a restituting force for the operating member 120 to move back to a predetermined position.
As a conclusion, the clamping device for the sprayer can is for assembling with the sprayer can to use and prevents a user from contacting with the sprayer can directly. The clamping portion can fix to the circumferential flange of the sprayer can steadily, and the circumferential wall of the clamping portion is designed to conveniently and easily assemble substantially and to have a strong structural strength.
While we have shown and described various embodiments in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
