ABSTRACT OF THE DISCLOSURE A dispensing button for controlling the dispensing of material under pressure from a container and having a directional tube provided With a cylindrical end rotatable in a socket in the button and a sleeve surrounding the button and engaging an annular shoulder on the tube adjacent the cylindrical end to prevent accidental displacement of the tube from the socket. The sleeve may also form an outboard bearing for the button and/ or tube to support them against lateral movement relative to the container.

This invention is an improvement over my U.S. Patent No. 3,148,806 wherein the directional button has a bent tube having one end rotating in a socket but there is no means to prevent the tube from being accidentally withdrawn from the socket. Also the button is supported on the valve actuator or stem and under some circumstances places an undue lateral strain thereon during the operation thereof or the adjustment of the tube on the button.

The present invention solves these problems by providing means on the button for locking the directional tube in the socket against accidental Withdrawal and, by providing when necessary, an outboard bearing means for stabilizing the button and directional tube during adjustment and use.

This is accomplished by providing the tube with a shoulder adjacent the cylindrical end thereof rotatably positioned in the socket on the button and by providing a member overlapping the shoulder to prevent the tube from being accidentally withdrawn from the button. As preferred, this member is a sleeve surrounding the button.

If the occasion requires support for the button against lateral displacement, the sleeve is fixed to the container and has a portion slidably receiving the button to support it for axial reciprocation. The sleeve has an openended elongate slot aligned with the socket on the button to receive the tube with the inner Walls of the sleeve adjacent the slot overlapping the shoulder on the tube and holding the tube in the socket in all operative positions of the button. If desired the slot can have a width substantially equal to the diameter of the tube to provide a bearing therefor as the tube is rotated in the socket to various dispensing positions.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

FIG. 12 is a top view of FIG. 10.

In the form of the invention shown in FIGS. 1 and 2 there is a valve actuating button 10. The button is normally held in the non-dispensing position of FIG. 1 and has an actuating portion 11 at one end to which pressure is applied to move the button inwardly to a dispensing position. The other end of the button is connected to the end of a valve operating member or portion 12 Which extends into a container C to operate the usual valve (not shown) when the button is in dispensing position to control the flow of material under pressure from the container. The button, as shown in FIG. 1, has a passage 13 for conducting the material from the container to a cylindrical socket 14 in the sidewall of the button.

An elongate directional dispensing tube 15, preferably a bent tube, has a longitudinal passage 16 therein through which the material flows and has a cylindrical end portion 17 rotatably received in the socket with the passage 16 in communication with the passage 13 to dispense the material from the container in the various rotative positions of the tube with respect to the button.

In accordance with the present invention means is provided for preventing the tube from being accidentally withdrawn from the socket. As illustrated, the tube is provided with an outwardly facing shoulder 18 at the end of the cylindrical portion 17 and a member 19 on the button overlaps and engages the shoulder 18. While this member can take various forms, it is preferred to form it as a sleeve 20 surrounding the button.

To facilitate the assembly, the sleeve has an elongate open-ended slot 21 which is aligned with the socket and straddles the tube as it is put in place after the tube is inserted into the socket. When in position the inner surface of the sleeve adjacent the sides of the slot will overlie and engage the shoulder on the tube, as shown in FIGS. 1 and 2, and prevent accidental withdrawal thereof from the socket.

If it should be desired to stabilize the button against lateral movement during the operation thereof and the adjustment of the dispensing tube to its various dispensing positions, the form of the invention illustrated in FIGS. 3 to 9 can be employed. In this form of the invention a sleeve 120, which may be molded or formed from a plastic or other resilient material, is so constructed at its inner end so as to fixedly fasten it to the container C when an annular rib 122 is snapped under a shoulder 123 on the container C.

The sleeve at its outer end is provided with a bore 124 forming an outboard bearing slidably receiving and sup porting the button 10 against lateral movement during the reciprocation thereof between normal and dispensing positions. The sleeve has an elongate slot 121 opening in the outer end which is aligned with the socket 14 in the but ton and through which the tube passes when in position on the button. The slot is long enough to permit the button to move from normal non-dispensing position, as shown in FIG. 3, inwardly to dispensing position when pressure is applied to the actuating portion 11 causing the operating portion 12 to operate the valve to dispense material from the container through passage 13 to the dispensing tube.

As shown in FIGS. 4, 5, 6 and 9 the inner sides of the sleeve adjacent the slot 121 overlie the shoulder 18 on the tube 15 in all rotative positions and prevents the tube from being accidentally removed from the socket.

In the preferred form of the invention the slot 121 in the fixed sleeve has a width substantially equal to the diameter of the tube so that it will engage the tube and provide an outboard bearing therefor to stabilize it during its rotative adjustments with respect to the button to different dispensing positions and prevent possible lateral movement of the button during such adjustments.

If desired, the sleeve 120 can have a recess 125 in the side thereof forming an abutment 126 disposed below the slot to be engaged by a member 127, herein shown as a portion of the tube 15, when the tube is in a non-dispensing position alongside of the container 10 as shown in FIG. 4 to prevent accidental movement of the button inwardly to operate the valve controlling the dispensing of the material from the container. When it is desired to dispense the material, the tube is turned from the position of FIG. 3 to the desired dispensing position of FIG. 4 moving the member 127 out of engagement with the abutment 126 and freeing the button to move inwardly to operate the valve.

Under some circumstances, it may be desirable to block the movement of the button through a wider range of movement of the tube. Such a device is shown in FIGS. 10- 12 wherein the recess 125 in the sleeve 12Gb has a fiat surface 130 (FIG. 12) on the side which lies in a plane perpendicular to the axis of rotation of the tube and has an arcuate abutment 126b disposed below the slot 121k for engaging the member 127 on the tube. As is clear from FIG. 11 this will prevent accidental operation of the button for a substantial arc of movement thereof on either side of the normal non-dispensing positions in which the tube is disposed along the side of the container. In the specific form illustrated, the arc is approximately 65% but it can be varied as required.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
