1937. R. BERNHARDT CONTAINER AND PUMP Filed Sept. 12, 1933 Pastas maze. i937 Rudolph Bernhardt,-Chioago, III.

' This invention relates to pumps or spraying devices of the type adapted to bemounted in a bottle or container for pumping or spraying the con- .tents therefrom and is particularly directed to 6 devices of this kind shown and described in myapplication for Pumps, Serial No. 645,554, now.

matured into Patent No. 2,025,846, dated Decem-' ber 31, 1935, which are adapted to be supported I and manipulated-with one hand.

1 It is frequently desirable to mount such pumps or sprayers in the containers and ship the same fllled with the spraying liquid and certain features of this invention are particularly'directed to means for supporting the pump and holding 15 the same in depressed position'and securely sealed to prevent discharge'or loss of the liquid.

The objects of this invention arein general to provide an improved container with a pump mounted therein; to provide apump having a 6 combined seal and support for a hollow pump rod or tube; to provide a bottle or-the like with a cap of relatively thin or light material andhaving associated therewith means for gui i the pump rod and means for locking the pump with the rod in; retracted and sealed position; and to provide such other advantages and-novel features as will be described hereinafter and set forth in the claims. a

In the accompanying drawing illustrating this invention,

Figure 4 is a sectional view taken on line v4-4 40 of Figure 2; and

Figure 5 is a sectional detail taken on the line 5-5 of Figure 4.

As shown in the drawing, the container is mma trated as a bottle 6 having a screw cap 'I of the 45 type more or less commonly used for closing the same. A washer or gasket 8 is inserted between the cap and the threaded neck 9 of the container for making a tight joint between the neck and the cap. A metallic washer or disc i0 is inter- 50 posed between the gasket 8 and the cap and has a central depressed portion ll forming a portion of a chamber for receiving a packingiring. The disc III has a downwardly projecting cylinder or 7 bearing ii for the reciprocable hollow pump rod ordischargetube i3. Thispumphasacylinder Appllca'tionsepteinber 1a. s'sa sa-u is csam' z Olaimau (or. semi) 14 which is adapted container and is of the type having a springfor to rat on thebottom of the l the rodrthe rod belhs depressed for the dischargemovement by means of a finger piece II. The pump is provided with a nozzle i6 hav- 5 ,ing a discharge oriflce II but asthe pump is otherwise of well known construction further description is unnecessary. However, it will be noted that the spring tends to raise the rod and 4 parts associated therewith up to the position showninFigure 1. cwhenthepumpistobeop erated the operator presses down on the thumb piece It and thereby pushesin or depresses the pump'rod l3 against the tension of the spring in the cylinder, which presses against the pis- 15 ton and tends to normally hold the rod is in raised position, as described in my co-pending application. This provides the discharge stroke. As soon as the pressure on the thumb piece is released the spring again raises the piston and pump-rod ii to raised or projected position as shown in Fig. 1. This reciprocation of the pump rod and associated parts therefore accomplishes the pumping operation as will be readily understood by those familiar with the art.

The caps commonly used for such bottles. are usually made of tin or other relatively light metal and in order to provide locking means for holding the rod IS in depressed position against the tension of the spring and to securely pack the same, a plate or disc is is arranged with its outer edge is engaging with a peripheral recess in the horizontal portion .of the disc II. The central 14 flxed on the rod IS. The detent 24 may be secured to the rod in any suitable manner, but

in the arrangement shown it is applied thereto 5 when circular in form and with a circular hole therethrough for receiving the rod. After this member is placed in position it is flxed to the rod by being flattened or compressed which at the same time causes the rod to be slightly flattened or compressed as shown particularly in Figure 4. This detent also hasoutwardly extending pro- Jections or lugs 25 which 'are adapted to pass down through slots or recesses 28 in the sides or inwardly projecting flange of the upwardly projecting portion of the plate IS. The plate I! is also provided adjacent to the central opening with raised portions 21 preferably at right angles to the recesses 26, such raised portion providing pockets or depressions for receiving the lugs 25 after the lugs have passed through the slots 26 and been turned under the edge of the plate to locking position. By means of this arrangement it will be seen that I provide a fastening in the nature of a bayonet joint for holding the parts in depressed position as shown in Figure 2. When in this position the packing ring 23 is pressed tightly against the bottom of the disc ill or the upper end of the tube l2 which is fitted therein, thereby making a tight Joint between the pump rod l3 and the other closure members. When in this position the package or container is adapted to be shipped without having the contents leaking out and it will also require less room for packing on account of the retracted position of the pump rod and connected parts. In order to further prevent any leakage I provide a cap or thimble 28 which is preferably made of light sheet metal or other suitable material and which fits closely over the nozzle I. This cap is preferably provided with thumb pieces 28 for convenience in applying and removing the same.

While my improved device may be made in any desired sizes, .the illustrations are made from commercial forms which are relatively small and adapted to be used with one hand. Thecup shaped plate I8 is preferably made of heavier material than the cap and thereby furnishes a substantial and lasting locking member for cooperation with the detent and packing ring.

While I have shown a preferred form of my invention it will be noted that changes may be made in order to adapt it for diflerent uses and it is to be understood that the invention is not limited to the specific structure other than as set forth in the following claims, in which I claim:

1. The combination with a bottle, of a screw cap, a packing member arranged between the cap wardly through the bearing and having resilient means tending to hold the rod in outwardly projected position, an inverted cup-shaped member projecting upwardly through an opening in the cap and having a flange secured between the cap and the disc, said member having a central opening therethrough with notches in the edges, said disc and said cup shaped member forming a chamber, a washer engaging with the pump rod at a distance abovethe top of the bottle when the rod is in raised position and secured thereto by being deformed together with a portion of the rod, and having lugs thereon, and a packing ring around the rod below the washer, the arrangement being such that the washer and ring may be pressed downwardly into the chamber between the disc and the cup-shaped member with the lugs passing through said notches and the washer turned to bring the lugs into fastening position to hold the'rod in closing position.

2. The combination with a bottle, of a closure, said bottle having a neck and having a reciprocating pump mounted therein with its piston rod freely movable through the closure, said closure comprising acap formed of thin metal mounted on the bottle and having a centralopening therethrough, a disc positioned betweenv the top of the bottle and the cap, a bearing mounted in the disc and engaging with the rod, an annular plate formed of heavier material than the cap which is positionedbetween the disc and the cap and having a raised portion extending outwardly through said central opening in the cap said disc and plate being marginally secured to the bottle neck by the cap, means associated with the rod adapted to detachably engage with the plate and hold the rod in retracted position, and means for making a tight packing between the rod and the bearing.
