Patented Aug. 6, 1940 UNITED STATES PATENT OFFICE 3 Claims.
This invention relates to a novel cap applicator for fluid dispensing containers.
Among the objects of this invention are to provide novel and more eflicient means for support- 5 ing the rubbing cloth or fabric on a cap applicator, said means also controlling the fluid dispensing valve; said means comprising a dome-shaped spring for operating said valve which by reason of its shape also serves as a support for the rubbing cloth or fabric. A further object is to provide novel means for securing said fabric to the cap member.
For a more complete understanding of the invention, reference is made to the accompanying drawing, illustrating the invention, in which like reference characters refer to like parts throughout the several views.
Figure 1 is a front elevation of a container showing in section my novel dispensing device at- 20 tached thereto;
Figure 2 is an enlarged plan View of my novel valve spring and fabric support;
Figure 3 is an enlarged section through a detail of the cap member showing the valve and 5 spring structure.
As shown in the drawing, the container I has attached thereto a unit comprising an inner cap member 2 and an outer cap member 3. The top 2a of the inner cap member has a metal foil liner 2b, spaced from each other by cork or other suitable material, the cap and liner having a central aperture at 4 which is controlled by a valve 5 which, in turn, is controlled by a dome-shaped spring 6. The foil liner form's a good seating surface for the valve 5. The dome-shaped spring has spaced legs 1 which extend downwardly from the high point thereof to rest upon the cap member 2 and these legs have crimped or upwardly turned edges 8 which serve as fabric gripping means as will hereinafter be described.
The valve 5 has a shank 5a which extends through the aperture 4 and passes through a central hole 2| in the dome spring 6. The shank 5a is secured to the dome spring by having the 45 end 22 upset or peened over as shown. In its normal, closed position the ball portion 23 of the valve is seated against the slightly bevelled edge [8 of the aperture 4.
A layer of felt or other suitable material 9 is placed over the dome spring 6 and a layer of suitable rubbing fabric is placed over the felt. The outer cap member 3 has an upwardly extending portion II which extends above the top of the inner cap member and has an inwardly extending flange l2 with a downwardly turned The dome spring 6, between the legs 1, has downwardly extending segments l9 which act as stops to limit the movement of the spring '6 in the direction of the cap, and thus eliminate the possibility of pressing the spring so closely against the opening 4 as to close the same. They also serve to prevent undue pressure which might weaken or break the spring. A cover I4 is provided for the entire unit and is seated upon a shoulder formed in the outer cap member 3. The outer cap member} is soldered, crimped or otherwise secured at [6 to the beaded edge I! of the cap member 2. Thus the caps 2, 3, and the related parts may be applied to or removed from any receptacle as a unit.
In the operation of the device, the container I being filled with a cleaning fluid, for example, downward pressure against the cloth I l] acts on the dome-spring 6 and this, in turn, causes operation of the valve 5 which moves away from its seat l8 to permit the flow of fluid from the container. The fluid will flow into the chamber 20 and thence between the feet 1 to impregnate the felt and rubbing cloth. Release of pressure upon the container causes spring 6 to close the valve 5 and shut ofi the flow of fluid from the container.
Having thus described my invention, I wish it to be understood that the drawing and description are merely for the purpose of illustrating the invention and are not to be construed as limiting me to the construction and arrangements shown. Changes in the construction and arrangement of parts may be made without departing from the spirit of the invention as defined by the appended claims.
A liquid dispensing applicator for receptacles comprising a cap member adapted for attachment to the mouth of a receptacle, an aperture in said cap and a valve therefor, a domeshaped spring for controlling said valve, said spring having legs with upturned edges resting on said cap, a fabric extending over said cap and spaced therefrom within its marginal edge by said dome spring, a securing means for said fabric mounted on said cap, said fabric being clamped along its marginal edge between the upturned edges of the spring legs and the securing means.
2. A liquid dispensing applicator for receptacles comprising inner and outer cap members, the inner cap member having an aperture in the top thereof and a valve therefor, a dome-shaped spring for controlling said valve, said spring having legs with upturned edges resting on said inner cap, a fabric extending over said inner cap and spaced therefrom in dome-like shape within its marginal edge by said spring, the outer cap member having a portion extending above the top of the inner cap and having an inwardly bent flange, the fabric being clamped along its edge between the upturned edges of said legs and the flange of said outer cap member.
3. A liquid dispensing applicator for receptacles comprising inner and outer cap members,
the inner cap member having an aperture in the top thereof and a valve therefor, a dome-shaped spring for controlling said valve, said spring having legs with upturned edges resting on said inner cap and having means for limiting the movement of said spring towards said cap, a fabric extending over said inner cap and spaced therefrom in dome-like shape within its marginal edge by said spring, the outer cap member having a portion extending above the top of the inner cap and having an inwardly bent flange, the fabric being clamped along its edge between the upturned edges of said legs and the flange of said outer cap member.
