This invention relates to a device for dispensing material such as powdered soap and other fluent products.

An object of the invention is to provide a 3 device for dispensing a limited quantity only of the dispensable material upon each operation of the actuating means.

Another object is to provide such a device having means associated therewith for precluding leakage and wastage of the dispensable material.

Another object is to provide a dispenser having novel valve means associated therewith.

Another object is to provide such a device which is simple and efficient in construction and operation.

rlhese and other objects are attained by the means described herein and disclosed in the accompanying drawing, in which:

Fig. 2 is a fragmentary view of the lower portion of the device shown partly in section and disclosing the device in a dispensing position.

Fig. 3 is a. cross-sectional view taken on the $0 line 3-3 of Fig. 1. j

The dispensing de'vice comprises a container having a body portion 1, preferably cylindrical in form, a lower .portion 2 slanting inwardly of the body, and a lower portion or neck 3 of a reduced cylindrical shape. In the upper portion of the body 1 a bearing strip 4 is secured transversely of the center of said body. This strip may be provided with side flanges 26 for purposes of reinforcement. At the center of said strip is provided a transverse slot 5 which continues through one of the flanges 26 for the purposes to be described and opening upon one edge of said strip. A retaining plate 6 is remov- 5 ably attached upon the central portion of strip 4 and is provided with a slot 7 adapted to extend oppositely to the slot 5 for-provid lng the aperture 8. A push rod 9 has its upper end slidably positioned in the aper ture 8, the lower end of the rod projecting 5o outwardly of the reduced portion or neck 3 of the container and being provided with a button 10. Adjacent its upper end, the rod 9 is formed with a shoulder 11 adapted to abut the underface of strip 1 for limiting up- 55 ward movement of the push rod. At the extremity of its upper end, the rod is provided4 with an abutment 12, such as a nut, which limits downward movement of the push rod.

A coil spring 120 is positioned upon the rod 60 between the strip 4 and a wire fork member 13 secured to an intermediate portion of the rod as at 14. The spring 120 normally urges the rod to its lowermost position. The Jfork member 13 is adapted'to stir up the contents a5 of the container upon rotation of the rod 9 on its longitudinal axis.

1n the neck -portion 3 of the container is positioned a pair of valve seats 15 and 16 respectively. Upper valve seat 15 may consist 70 of a circular stripl attached along one edge to the inner face of neck 3 and having the body thereof bent inwardly of the container to provide the inwardly projecting valve seat shown. The lower valve seat 16 may con- 75 sist of a strip having one longitudinal edge secured to the inner face of neck 3 and the remainder of its body 18 formed to project inwardly of said neck to provide the lower valve seat. The bottom edge of neck 3 may be ren- 80 dered smooth by curling as at 17. The free edge of the seat 16 may be further bent inwardly of the neck 3 as indicated at 19.

Upon the rod 9 are provided an upper valve 20 and a lower valve 21 adapted to coop- 85 erate with the upper and lower valve seats respectively. Both of these valves provide preferably downwardly divergent outer surfaces as shown. In addition the edge of the lower valve may be formed with a slightly downwardly -upon ared portion 22 adapted to seat snugly against the inwardly turned portion 19 of the coo erating valve seat.

llig. 2 lllustrates the normal non-dispensmg position of the device of this invention. It will be seen herein that the association of the valves with their respective valve seats is such that when the lower valve 2l is sealed against the valve seat 16, the upper valve is open for permitting a limited quantity of the dispensable material to enter the space between the upper and lower valves. By reference to Fig. 2 it will be seen that when the push rod 9 is actuated upwardly, the upper valve 20 is closed for precluding downward passage of the dispensable material thereabove. It will further be seen that when theI upper valve is closed, the lower valve 21 is open for permitting dispensing of the limited quantity of fluent material held between the valves as explained, It will be seen that no matter how long the push rod is held upwardly, no further dispensing of the material will be effected inasmuch as the upper valve at this time remains continuously closed. Hence it is necessary to actuate the rod successively in order to eiect further dispensing whereby wastageof the material is prevented. The spring 120, as above mentioned, normally urges the push rod downwardly whereby the lower valve is held closed. The peculiar formation of the cooperating free edge portions of the valve 21 and its seat 16, is such as to eifect an eiicient seal against leaking of the material from the container. The top of the body portion 1 of the container may be provided with a removable lid b 23 to which one end of a chain 24 may be attached, the other end of the chain being secured to the body portion of the container, or as shown, to the uppermost of a pair of support brackets 25 secured in alignment upon the body of the container and adapted to be secured to a supporting surface for holding the dispensing device in its proper vertical position.

It will be seen by reference to Fig.` 3 that the push rod 9 may be moved laterally out of position for permitting removal or replacement of the spring 120 or the fork member 13. This arrangement and cooperat on of `the push rod and the plate 6 likewise has to do with the assembling of the dispensing device. In assembling the device, the button 10, which may have a threaded connection with the end of the push rod, may be removed. from posltion. The rod, with the valves 20 be and 21 previously secured thereon and the fork member 13 in place, may be inserted downwardly through the body portion and thel neck portion of the container. The sprlng 120 is now positioned and depressed the rod 9 until the top of said rod has been slipped into the slot 5 provided inthe cross strip 4. The spring is held depressed until the retaining plate 6 and the nut or abutment 12 have been properly placed in position as'indicated in Fig. 1. The valve seat 16 may now be slipped over thevlower end of the rod 9 and secured in cooperatingl relationship with the lower ing said valve seat in the y described and illustrated. Thereafter the button 10 may be replaced upon the rod and the dispensing device is in readiness for positioning anduse.
