Description

Aug. 25, 1931. J. M. HO THERSALL 1,820,192
CONTAINER CLOSURE Filed March 30. 1929 INVENTOR ATTORNEY Patented Aug. 25, 193* UNITED STATES PATENT OFFICE JOHN M. HOTHERSALI, OF BROOKLYN, NEW YORK, ASSIGNOR '10 AMERICAN CAN COMPANY, OF NEW YORK, N. Y., A CORPORATION OF NEW JERSEY CONTAINER CLOSURE Application filed March so, 1929. Serial No. 351,194.
This invention relates in general to a container and hasmore particular reference to an improved screw nozzle and cap construction, the cap being provided with finger holds to permit easy securing to and removal from the nozzle.
A principal object of the invention is the provision of an improved screw cap formed from a single piece of sheet metal and having finger holds struck out from the wall of the cap, permitting easy rotation thereof for threaded engagement with. and disengage ment from a container part.
Another important object of the invention is the provision of a screw nozzle cap having a retaining seat for a gasket by means of which a tight seal may be obtained upon threaded engagement of the cap with a container nozzle.
An important object of the invention is the provision of a container closure comprising a threaded container part having a gasket supporting flange and a threaded cap provided with finger holds by which the cap may be rotated to tightly press a gasket upon the flange of the container part when the cap is threadedly secured thereto.
Numerous other objects and advantages of the invention will be apparent as it is better understood from the following description, which, taken in connection with the accompanying drawings, discloses a preferred embodiment thereof.
Referring to the drawings:
Figure 1 is a side elevation of the upper part of sheet metal container provided with a nozzle and cap construction embodying the present invention;
Fig. 2 is an enlarged vertical sectional view through the nozzle, gasket and cap showing the closed position of these parts,-
and
Fig. 3 is a plan view of the container and closure disclosed in Figure 1.
To illustrate the invention I have disclosed in the drawings a container oflthe central nozzle type which comprises a cylindrical body ,11 having a top end 12 secured to the body by a double seam 13. Top 12 is formed with a substantially frustro-conical breast part 14 merging near its upper end into a threaded neck or nozzle 15. A horizontal flange 16 enclosing a discharge opening 17 terminates the upper end of the nozzle.
The opening 17 of the nozzle 15 is adapted to be closed by an open bottomed cap 18 having a side wall 19 in which is formed a threaded portion 21 which permits threaded engagement with the nozzle 15 when cap 18 is applied thereto. A gasket retaining seat 22 is provided in the top part of cap 18 in which ispositioned a gasket 23. Gasket 23 is preferably formed of a core piece of fibrous material covered or lined on its lower surface with a disc 24 of soft impervious material such as lead foil.
Cap 18 is provided with one or more projecting finger holds struck out, in the shape of arms 25, for turning the cap, from the metal forming the side wall 19, preferably just above the threaded portion 21. These finger holds in no way interfere with the cooperation of the threaded portion 21 of the cap 18 and the threaded part of the nozzle 15. They at the same time provide an increased leverage to permit tightly screwing cap 18 on nozzle 15 thereby uniformly clamping the interposed gasket 23 between the top of the cap and the flange 16 of the nozzle. In this sealed position the impervious lining 2A, backed up by the fibrous core of gasket 23 and coacting with the flange 16, forms a continuous air-tight covering for the nozzle opening 17.
It is thought that the invention and many of its attendant advantages will be understood from the foregoing description and it will be apparent that various chan es may be made in the form, construction an arrangement of the parts, without departing from the spirit and scope of the invention, or
sacrificing all of its advantages, the form:
ing said opening, said cap being provided I with a gasket retaining seat and having a portion of the side wall thereof extended outwardly beyond said screw threaded portion to provide a finger hold, and a gasket positioned within said seat and brought into engagement with said nozzle flange whe said cap is screwed on said nozzle.
2. A screw threaded cap for use in a container closure comprising an open-bottomed, one piece shell having a side wall formed with screw-threads, outwardly extended projections formed in said side wall above said screw threads to provide finger holds, and a gasket positioned within a retaining seat formed in said screw threaded cap.
3. A nozzle-cap for a container, formed of a single piece of sheet metal having a top cylindrical seat to retain a gasket, and near said seat struck out in the shape of radial arms forming finger holds for turning the cap, and below said arms formed with a screw-thread for engagement with a nozzle.
