Application January 5, masseria! No. 575 1 claim. (ci `azi-16) `This invention relates to dispensing receptacles and, more particularly, to 'receptacles'adapted to dispense their contentsin'an inverted position and provided with a. self-closing outlet.

5 A` feature of one embodiment of the invention is that the closure may readily be adjusted to dispense liquids of different viscosity,'that is, if the closure is positioned to dispense free-flowing liquids, it may readily be adapted to emit more viscous liquids. y

A further feature is that the closure' is adapted to prevent liquid droplets remaining on the closure valve when the receptacle is righted smearing and congealing on the outer surface of the closure device.

An object of the invention is to provide a simple. durable dispensing medium that can be manufactured inexpensively and assembled readily.

Other features and advantages will appear in the following description in conjunction with the drawings, in which- Figure 1 is a front elevation of the improved dispensing receptacle; Fig. 2, a plan View; Fig. 3, an enlarged broken vertical sectional view; Fig. 4, a vertical sectional view of a modification; Fig. 5, a plan view of a liner employed in the modification of Fig. 4; Fig. 6, a vertical sectional view of another embodiment; Fig. 7, an elevation of a valve nipple; Fig. 8, an elevationof a coil spring; and Fig. 9, an elevation of a liner.

Referring to the drawings, the reference character T designates a receptacle of any desired type adapted to contain a liquid to the dispensed. As here shown, it represents a small glass bottle adapted to contain a lotion. The bottle 'l is provided with a neck 8 to which a cap or top, constructed in accordance with my invention, is adapted to be secured. This neck may have a smooth surface so that the cap or top may it frictionallythereon, but as shown in Fig. 3 at 9, it is preferably threaded to receive a correspondingly threaded cap or top.

The cap I0, preferably fashioned from phenolic condensation material, comprises a Irusto-conical upper portion I I and a cylindrical lower portion I2. The lower portion I2 is shown screwthreaded at I3 to coact with the threaded neck 8 of the receptacle and has a vertical portion Il extending above the threads. The frusto-conical portion I I terminatesin a centrally located aperture adapted to receive tapered valve means I5. The upper edge I6 of the cap in Contact with the valve inclines slightly downwardly and inwardly to form a groove for a purpose to be explained. The skirt I1 formed on the base of the valve I5 is adapted to bear against a shoulderll 8 in the inner part of` the `apex o the cap. Thebaseof the valve is also provided withanotch I 9 to house the upper section of a coil spring 20 adapted to yieldingly hold the skirt of the valve I1 against the 5 shoulder I8 of the cap. The lower convolution of the spring 20 rests on an annular centrally apertured washer or liner ZI disposed on the top of the neck of thereceptacle. The spring 2B likewise serves to yieldingly retain the washer 2| on l0 the bottle top to form a seal thereon when the receptacle is inverted.

It will be readily understood that to remove the liquid from the container, the container is inverted and by the application of slight pres- 15 sure on the valve member I5, the valve will be unseated, permitting the ow of the liquid contents from the closure. The removal of pressure on the valve closes the cap and immediately halts the iiow of liquid. The provision of the 20 groove I6 on the edge of the closure tends to retain liquid dropletsremaining on the edge and to prevent its ilow along the outside of the closure.

It is also to be understood that the closure described may be adapted to control the ilow 'of liquids of varying viscosities, that is, if the receptacle contains a free ilowing perfume and it is desired to substitute a more viscous liquid, it is unnecessary to change the entire closure device since by turning the cap one-half revolution in a counter-clockwise direction-or more, depending on the viscosity of the liquid and the pitch of the screw-threads, vthe tension onv the coil spring is lessened and the annular opening formed by unseating the valve is greater without a substantial increase in the pressure applied to the valve. Conversely, the closure may be adapted for the admission of a less viscous liquid by turning the cap in aclockwise direction to form a smaller annular opening on the application of the same force.

A modified closure is shown in Figs. 4 and 5. In that embodiment the screw-threaded cap 30, tapered .valve `22 and coil spring 23 are similar 45 to those shown in Figs. 1-3 and 7-9. The lower coil of the spring rests on a liner 24 pre!- erably fashioned from a phenolic condensation product and equippedwith threads 25 to engage they threads 26 on the interior of the cap. The 50 liner is preferably provided on its upper surface with an annular groove 21 adapted to receive the lower convolution of the coil spring and it may likewise be equipped with suitable apertures 28 in which the prongs of a forked mem- 55 ber may be inserted to assist the insertion and removal of the liner. An annular thin cork or paper seal 29 may bedisposed between the liner and the bottle top to form the seal therebetween in shipping, it being understood that the seal may be readily rupturedwhen the liquid is to be removed. Y

A further modincation is shown in Fig. 6. In that modiilcation, the screw-threaded cap I0, tapered valve 4|,Vcoil spring, and centrally apertured liner 43 are similar to those previous- 1y described and shown in Figs. 1 to 3. The valve 4I, the coil spring 42 and the liner Il shown in Figs. 7, 8 and 9, respectively, are the same as the members described in Figs. 1 to 5, and may be employed therein, except that the liner Il differs somewhat from the liner 24 of Figs. 4 and 5. The interior of the closure cap 4I is provided with a centrally located depending ridge or wedge-shaped portion M. Upon assembling the closure, a portion of the liner 43 adjacent its periphery bears against the ridge portion M, spreading the periphery slightly to secure a tight nt in the closure and a seal above the hner.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claim, in which it is my intention to claim al1 novelty inherent in my invention as broadly as permissible, in view of thev prior art.

What I claim as new and desire to secure by l0 Letters Patent is:

In an adjustable closure for dispensing receptacles, a hollow closure-cap having a cylindrical portion terminating in a nozzle, a springseat member movable vertically within the cyl5 lindrical portion of said cap, spring means dis- 'posed on said seat member, and a tapered member protruding from said nozzle, normally closing the same by the pressure of said spring and forming an annular opening in said nozzle when 20 pressed inwardly, the size of the opening for a given inward pressure depending on the position of the cap on the receptacle.
