The prior art pressurized fluid containers for portable sprayers have been constructed in such a manner so that the container has been provided with an access opening and with a separate opening for the mounting of the pressure pump. The prior art structure is not advantageous because of an access opening and a separate opening to install the pressure pump increases the cost of making the container. Accordingly, it is an important object of the present invention to provide a novel and improved pressurized fluid container which is adapted to overcome the aforementioned disadvantage of the prior art pressurized fluid containers for sprayers.

It is another object of the present invention to provide a pressurized fluid container for a portable sprayer which is provided with a single access opening in the upper wall thereof which is enclosed by a dual-purpose cover that functions to seal the access opening and also functions to support or carry a pressure pump for cre ating pressure in the container.

. It is a further object of the present invention to pro vide a pressurized fluid container which is provided with a single access opening that is closed by a combination cover and pump structure which is simple and compact in construction, economical to manufacture, and efficient in operation.

It is still another object of the present invention to provide a pressurized fluid container which includes an upper horizontal wall and an oblong access opening therethrough. An oblong cover is disposed inside of the container upper wall for sealing engagement with said oblong access. A locking member is pivotally mounted on the cover for movement to a locking position, for operative engagement with the outer side of said container upper wall to lock said cover in place, and for movement to an unlocked position to release said cover for removal from said container. A pump is attached to the inner side of said cover and it is provided with a piston rod which is extended outwardly through the cover. A pump operating handle is attached to the outer end of the piston rod and means is carried on the locking member for retaining the handle in a position locked against axial movement, whereby the pump handle may be used to rotate the locking member between the locking position and the unlocked position, and also be used for a cover handle, and further, whereby the handle may be used to operate the pump piston rod when the cover is locked in position on the container upper wall.

Other objects, features and advantages of invention will be apparent from the following detailed description, appended claims, and the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, and in particular to FIG. 1, the numeral 10 generally designates a pressurized fluid container of the type employed in portable sprayers for holding insecticides or other chemical preparations and wherein the container is adapted to be carried on a shoulder strap by the user. The numeral 11 designates an upper horizontal container wall which is provided with an access opening which is oblong in shape, as shown in FIG. 4, and which is surrounded by an inwardly extended flange 12, as shown in FIG. 1. Sprayers of the aforementioned general type are equipped with an air pressure pump which is manipulated by hand to build up a pressure in the container by means of which the liquid is discharged through a spray nozzle. The numeral 13 generally designates such an air pressure pump in FIG. 1. The numeral 14 designates a discharge hose to which is connected a suitable spray nozzle. The discharge hose 14 is connected to a suitable internal liquid tube 15.

As best seen in FIG. 6, the cover structure of the present invention includes an inner circular plate 16 which is integrally formed on the upper end of a cylindrical vertical wall 17. Integrally formed on the lower end of the wall 17 is a horizontal, oblong flange 18 which is provided with an outer shape that is identical to the shape of the oblong access opening in the container upper wall- 11, and which is adapted to be slidably received within said access opening. A vertical, downwardly extended flange 19 is integrally formed around the outer periphery of the flange 18 and a horizontal flange 20 is integrally formed on the lower end of the vertical flange 19. It will be seen that the horizontal flange 20 carries a suitable rubber gasket or other suitable seal material 21. The gasket 21 is adapted to be seated against the access opening flange 12 when the cover is in the closed position shown in FIG. 1.

As shown in FIG. 6, the air pressure pump 13 includes a cylinder 22 which is enclosed by a top end plate 23. The plate 23 is fixedly attached to the cover flange 18 by any suitable means, as by brazing 24. The cylinder plate 23'encloses the lower end of the cylinde wall 17 of the cover structure.

As shown in FIG. 6, a cylinder rod guide bushing 25 is extended downwardly through suitable holes in the cover plate 16 and the cylinder top end plate 23. The guide bushing 25 is secured in place by suitable brazing 26 which attaches the bushing 25 to the cylinder plate top endplate 23. A locking member is pivotally mounted on the cover for movement between a locking position illustrated in FIGS. 1 and 3, and an unlocked position to release the cover for removal from the container as illustrated in FIGS. 2 and 5. The locking member includes a horizontal strap 27 which is pivotally mounted around the upper end of the bushing 25. The locking member further includes a pair of downwardly extended straps or legs 28 which are each integral at their upper end with one of the outer ends of the strap 27. The locking member further includes a pair of horizontal outwardly extended cam engaging straps 29 which are integrally attached to outer ends of the straps 28.

As shown in FIG. 3, when the locking member is rotated to the locking position, the locking straps 29 slide up over the locking cams 30 which are secured at one end thereof to the container upper wall 11 by any suitable means, as by the brazing 31. As shown in FIG. 7, the locking earns 30 are formed ,with an upwardly directed free end, opposite to the end which is secured in place by the brazing 31, so as to provide a spring action locking pressure against the locking member straps The numeral 32 in FIGS. 4, and 6 designates stop members to limit the rotational movement of the locking member relative to the cover structure. As shown in FIGS. 1 and 3, a U-shaped pump handle locking member is secured to the locking member top straps 27 by any suitable means, as by welding. The U- shaped pump handle locking structure comprises the horizontal strap 33 and the integral two vertically extended C-shaped members 34 which have the openings 35 on the one side thereof. As seen in FIGS. 1 and 3, the lower horizontal rod portion 37 of the pump handle 38 is adapted to be disposed in the C-shaped locking members 34 to retain the pump handle 38 in a locked position. The pump handle horizontal rod portion 37 is secured to, the upper end of the pump piston rod 36, as shown in FIG. 6. A coil spring 39 is disposed between the pump handle cross rod 36 and the handle locking plate 33. The spring 39 normally biases the handle 38 upwardly in a locked seating engagement in the C- shaped members 34.

It will be seen that the dual-purpose or combination container cover of the present invention may be locked in place by moving the pump handle 38 into the locked position shown in FIGS. 1 and 3. The handle 38 is also used for turning the locking member into the unlocked position shown in FIG. 5. When it is desired to operate the pump with the cover locked in the position shown in FIG. 1, the handle 38 may be released by pressing downwardly on the handle and turning the handle counterclockwise, as viewed in FIG. 3, to permit the lower handle bar 37 to be moved out through the openings 35 to free the handle 38 from the C-shaped locking members 34. The pump handle 38 may then be used in the conventional way to create a pressure inside of the tank 10. It will also be understood that the handle 38 may be used as a means for carrying a container preciated that the invention is susceptible to modification, variation and change without departing from the proper scope or fair meaning of the subjoined claims.
