HOLDERS AND VALVE CONTROLLING MECHANISM FOR PRESSURIZED CONTAINERS Filed Dec. 3, 195 7 United States Patent HOLDERS AND VALVE CONTROLLING MECH- ANISM FOR PRESSURIZED CONTAINERS Peter S. Vosbikian and Thomas S. Vosbikian, Melrose, Pa.

Many different types of material are nowv being marketed and sold in powdered, comrninuted, semi-solid, liquid or fluid form in pressurized containers provided at one end with a manually actuated, tensioned valve mechanism so that the material is automatically discharged from the container in the form of a stream or spray.

In such conventional construction, the operator holds the container in one hand and actuates the valve mechanism to effect the opening of the valve, thus permitting a controlled discharge from the container, or the operator can hold the container in one hand and press the valve control with the other hand. We have found that if a properly designed holder is employed which will snap on a shoulder of the cam or container, which has a grasping handle and a trigger device for controlling the valve mechanism, a more accurate amount of material can be discharged in a desired direction and the operation is more easily performed.

The object, therefore, of our present invention is to devise novel holders and valve control mechanism for pressurized containers.

A further object of the invention is to devise a novel construction and assembly of the component parts, and wherein spaced elements extend longitudinally from a grasping handle, one of such elements being adapted to snap on to an end of a pressurized container, the other element extending above the valve control of the valve mechanism, and a novel trigger arrangement to effect relative movement of said elements to cause the opening to a desired extent of the valve of the pressurized container.

A further object is to provide for varying the lever action on the valve controlling element.

With the foregoing and other objects in view as will hereinafter clearly appear, our invention comprehends novel holders and valve controlling mechanism for pressurized containers.

For the purpose of illustrating the invention, we have shown in the accompanying drawings preferred embodiments of it which we have found, in practice, to give satisfactory and reliable results. It is, however, to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not limited, except by the scope of the appended claims, to the exact arrangement and organization of these instrumentalities as herein set forth.

Referring to the drawings:

Referring first to Figures 1-3 and 8, the holder and valve controlling mechanism is provided with a grasping handle 1, preferably of plastic and in section with the sections secured together by a fastening device 2 and adhesive if desired. The sections near their upper ends are provided with complementary grooves 3 and 4 forming a longitudinally extending opening, and the top face has a longitudinally extending groove 5.

A container holding and valve operating device is carried by the handle and is in the form of a strand bent upon itself to form a longitudinally extending straight element 6 extending through the opening formed by the grooves 3 and 4, a loop at its rear end which merges into a forwardly extending valve controlling element 8 positioned in the groove 5 of the handle and preferably inclining upwardly and forwardly to its front end.

In Figure 2, we have shown a portion of a pressurized container 23 having at its upper end an annular shoulder 24 over which an open loop 25 at the front end of the element 6 has been snapped, and the element 8 terminates above a valve actuating member 26 of the container.

A trigger 9 is employed for controlling the valve operating element and this trigger has a vertical slot 10 in its front wall through which the elements 6 and 8 extend. The top wall 11 of the slot bears against the top face of the element 8 and the bottom wall 12 of the slot bears against the bottom face of the element 6. The trigger has side flanges having a pivotal connection with the handle by means of a pivot pin 13 as in Figures 1 to 4, or as in Figure 8 wherein side portions of the side flanges are in dented at 27 and extend into recesses in opposite sides of the handle as at 28 to form a removable pivotal connection as will hereinafter be explained. The top face of the element 8 may have longitudinally spaced notches 21 which serve as pivotal points for the trigger when it is not pivotally connected with the handle.

In the embodiment seen in Figures 5-7, a grasping handle 29 has the inner ends of a container supporting element 14 and a valve actuating element 16 secured to it, the element 14 terminating in an open clamping loop 15. The element 16 inclines upwardly and forwardly from the handle and near its front end may have a downward bend. Longitudinally spaced notches 17 on the element serve as pivotal points for a trigger 18 having a slot 19 with its upper wall 21 contacting the element 16 and its bottom wall 20 contacting the element 14.

The loop 25 may have a lip 22, and the loop 15 a lip 22 which forms a leverage point when the loop is snapped over the shoulder 24 of the container 23.

In the operation of the embodiment seen in Figures 1-4 and 8 assuming that the pressurized container has been connected with the loop 25, the operator presses the trigger rearwardly towards the handle thus causing the wall 21 to move the element 8 downwardly, the rear end of such element having a pivotal point at the loop and the front end will contact the valve controlling member 26 to open the valve and the contents of the container will discharge from the member 26 in the conventional manner. When the trigger is released, it returns to its initial position due to the spring action inherent in the valve actuating element 8. The length of the lever arm of the element 8 can be varied by moving the element 6 forwardly or rearwardly in its handle opening and such element may have a friction fit in such opening. If the pivot pin 13 is removed or the indentations 27 in Figure 8 snapped out of their recesses 28, then the trigger has a leverage action on the element 8 from a selected pivot location on such element, the trigger action then being the same as will W 3 be described in connection with the embodiment shown in Figures 5-7.

When the trigger 18 is moved from the position shown in full lines in Figure 6 to the position shown in dotted lines, it will be apparent that the valve actuating element 16 will be pressed downwardly to effect the opening of the valve mechanism by pressure on the member 26, and when released the element 16 will return to its initial position. The trigger may be moved forwardly or rearwardly on the elements 15 and 16 to vary the amount of lever action and while the notches 21 and 17 are advantageous they may be omitted if desired since the upper wall of the slot will pivot on the element at the point at which the trigger is located.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:

A support and control for pressurized containers, comprising a handle having a longitudinally extending opening through it and having a longitudinal groove in its top face, a' strand having a lower stretch extending through said opening terminating at its forward end in a clamping loop and at its rear end in a rear loop positioned in rear of the handle, said rear loop merging into an upper stretch seated in said groove and terminating above said clamping loop, and a trigger pivoted on the handle and having a transverse opening through which the upper and lower stretches of thestrand pass.

2. The construction defined in claim '1, wherein said lower e h has a fr s iqn fit.iatl .al2a9lasparin and is longitudinally adjustable therein.
