Application November 16, 1936, Serial No. 110,989 7 3 Claims. (01. 220-57) My invention relates to a pressure and sealing overhanging portion 3 to allowfor the insertion device for containers and I declare the following of the removable cover 6. to-be a full, clear, concise and exact description Removable cover 6 is oval shaped to conform thereof suficient to enable anyoneskilled in the to the'oval shaped opening 5 made by rim 3.

same, reference being had to the accompanying forming oval shaped opening 5 and tilted for indrawings in which like reference characters'resertion within container I. fer to like parts throughout the specification. A groove I0 is formed adjacent the periphery The object of the invention is to providea on the upper side of cover 6 to allow for the in- 10 pressure and sealing device for use more particusertion or mounting of a rubber gasket I I which 10:

Internal screw threads the device is shown assembled to the top of an in- 33 are formed on the inner surface of the uppersecticide container I having handles 2, 2 and a most part which cooperate with the screw'threads top rim overhanging portion 3 welded or other- I! in cap 20, whereby to draw removable cover wise secured to the-lateral cylindrical wall 4 upwards against overhanging rim 3 into sealing of the container I. An oval shaped central openposition.
ing 5 is provided by the top rim portion with an The lower surfaces of cams 26, 26 are serrated 55 or roughened at 34, whereby to effect a frictional contact with the upper surface of bridge l6.
A central aperture 35 is made through the upper surface of cap 26 for the projection of a piston rod 36 that extends down through an aligned aperture made in bridge member IE to engage a piston 31 operating in cylinder 39. There is also an outlet pipe that extends down to nearly the bottom portion 5| of the container in order to insure emptying the contents thereof when the sprayer is in use. The upper end of said outlet pipe 56 projects up through a central aperture in nipple 52. A ring 53 is used to hold the pipe 50 to the inside of container l as shown and described more particularly in my former Patent No. 1,971,727 issued August 28, i934.
A handle 38 is screw mounted to' the upperend of piston rod 36. Handle 381 is made to engage in a detachable manner the upper surface of cap 26, whereby to turn not only said cap 20 on and off throat H but also to be used in carrying the sprayer. To this end a disc 40 is formed integral with the lower part of handle 38. Two diamete rically oppositely disposed depending L shaped teeth 4|, 4| are formed integral with the lower surface of disc 40. Said L shaped teeth 4|, 4| are adapted to engage the upper surface of cap 26 by being projected through suitable apertures 42, 42 made therein for this purpose.
Each of the apertures 42, 42 is are shaped and provided with oppositely disposed offset openings 43, 43 for the insertion of L shaped teeth 4|, 4|, whereupon handle 38 is turned to cause the horizontal parts of L shaped teeth 4|, 4| to engage the under surface of raised portions 45, 45 formed integral with the upper surface of cap 26. Said raised portions 45, 45 provide upward countersunk recesses 44, 44, whereby to localize the position of teeth 4|, 4| when therein. It will be observed that there are two sets of raised portions 45, 45 to allow the handle to be turned either to the right or left and engage a set 45, 45. I
In operation the user will turn and tip removable cover 6 at right angles to its normal position with reference to the overhanging top part 3 of container In this position of cover 6 it can be inserted within container I. Bridge member H5 is mounted in place by inserting its central aperture over piston rod 36 before handle member 38 is screw mounted to its upper end or cap 20 screw mounted in place. Bridge member I6 is then dropped down in position within the opposite recesses l5, l5 in throat l4 and against the upper end of coiled spring '25.
When removing detachable cover 6 handle 38 will be turned to the opposite set of upwardly countersunk recess 44, 44 in cap 26' before starting to unscrew cap 20 with the aid of said handle 38.
The upper end of piston rod 36 is screw mounted in a suitably threaded countersunk aperture in disc 40 of handle 38.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is as follows:
1. In a pressure and sealing device for containers, a casing having an oval opening at its top portion, a removable member suspended Within said casing, whereby to fit and close said opening, an annular neck portion formed on said removable member, a cap member screw mounted to said neck portion, said neck portion having recesses formed therein, a bridge piece engaging said cap member and fitting within said recesses and a cam formed in said cap member, whereby the turning of said cap member will cause said cam to press against said bridge piece to draw the removable member into sealing position.
2. In a pressure and sealing device for containers, a casing having an oval opening at its top portion, an oval :shaped removable member suspended within said casing, whereby to fit and close said opening, an annular neck I portion formed on said removable member, a cap member screw mounted to said neck portion, said neck portion having recesses formed therein, a bridge piece engaging said cap member and fitting withing said recesses and a cam formed in said cap member, whereby the turning of said cap member will cause said cam to press against said bridge piece to draw the removable member into sealing position, a rubber gasket mounted on said removable member and a coiled spring mounted between said removable member and said bridge piece to aid in separating said removable member from said bridge piece.
3. In a pressure and sealing device for containers, a casing having an opening at its top portion, an-oval shaped removable member suspended within said casing, whereby to fit and close said opening, an annular neck portion formed on said removable member, a cap member screw mounted to said neck portion, said neck portion having recesses formed therein, a bridge piece engaging said cap member and fitting with said recesses and a .cam means formed in said 'cap member, whereby the turning of said cap member will cause said cam means to press against said bridge piece to draw the removable member into sealing position, a groove formed in said removable member, a rubber gasket mounted in said groove, a ridge formed on said top portion and contacting with said rubber gasket and a coiled spring disposed between said bridge member and said removable member, whereby to aid in separating said removable member from said bridge piece.
