Description

Patented Apr. 28, 1942 UNITED STATES PATENT OFFICEA 2,281,135 DISPENSER CAP John D. Becker, Chowchilla, Calif. Application June 21,1940, seriallNo. 341,646

(c1. zal-1s) 2 Claims.

having a pouring spout-normally closed by av movable flap, such flap having means associated therewith to automatically open the ilap upon the dispenser receptacle being titled from a normally upstanding position.

A further object of th'e invention is to provide a sanitaryv dispensing cap especially designed for use with a cream server or other liquid dispenser, but which is also admirably suited for use in connection with a dispenser for granular products such as sugar.

Another object of the invention is to provide a dispenser cap which can be readily disassembled for cleansing.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specication and claims.

In the drawing similar characters of reference` indicate corresponding parts in the several views:

Figure 1 is a top plan view of the improved dispenser cap.

Figure 2 is a sectional elevation of the cap aslapplied to a dispenser receptacle, illustrating the' pouring spout closed.

Figure 3 is a sectional elevation illustrating the cap with the pouring spout open.'

Figure 4 is a plan view of the closure plate.

Figure 5 is a plan view of the spout closing ap and actuating tongue.

Referring now more particularly to the characters of reference on the drawing, the device comprises a circular cap I formed with a common depending screw collar 2 adapted to removably and threadingly engage the upper end of a Y receptacle 3.

The cap I is formed with an integral, upstanding body 4 which extends diametrally across the upper surface of the cap; such body being of substantial height and elongated. Adjacent one end such body is formed with a downwardly and outwardly sloping face 5 which tapers in plan toward its outer end which forms an overhanging pouring lip 6. An upwardly and outwardly sloping opening I extends through the body 4 to a point adjacent lip 6 with which it forms a pouring spout; the inner end of said opening 1 being in communication with the interior o1 receptacle 3.

'I'he upstanding elongated body 4' is formed with a relatively deep trough or groove 8 which extends longitudinally in said body in upwardly opening relation. A closure plate 9 is removably but frictionally engaged in a channel II) which extends about the groove 8 adjacent the top thereof; said closure plate engaging in said channel from the end of groove 8 adjacent the pouring spout. At such end the closure plate 9 is formed with a downwardly angled ange II having a transverse slot I2 cut therethrough. A closure flap I3 normally rests of its own weight flush against the face 5, closing the outer end of passage I and overlying lip Ii. The rear end of ap I3 is formed with a rearwardly projecting tongue I4 which hingingly extends through and rearward slope, and at an acute angle to ilap I3. rI'he tongue has a relatively loose t in slot I2 so that the-nap may swing freely up and down relative to face 5. The portion of the tongue I4 within the groove 8 is of substantial thickness to prevent'escape of the tongue through said groove, this being accomplished by initially forming said tongue of substantially double length and folding the same in half, as clearly shown in Fig. 2.

A relatively heavy ball I5, such as a glass marble, is disposed in groove 8 and normally rests in the end of `said groove most remote from the pouring spout, and spaced from the tongue I4 of flap I3;V said ball normally being seated on a. bleed hole I6 extending through cap I into receptacle 3. The tongue I4 is of such length that it projects into the path of movement of the ball in said groove.

When the receptacle 3 is disposed vertically, the flap 3 closes passage 1 and ball I5 closes bleed hole I 6. However, upon the receptacle 3 being tilted in a direction to pour the contents thereof through passage 1 and over pouring lip 6, the ball I5 rolls toward the opposite end I1 of groove 8. With such movement of the ball it strikes tongue I4 and swings the same into abutment with said end I1 of groove 8, causing the flap I3 to swing away from the pouring lip 8 whereby to open the pouring spoutf In addition air then bleeds through hole I6 into receptacle 3, preventing any tendency to vacuum. Upon the receptacle being returned to anormal vertical position, ball I5 rolls away from end I1 of groove 8, retracting from tongue i5 and permitting nap i to return to a normal closed position.

In order to cleanse the above described dispenser cap, the closure plate 8 is drawn out of channel l0, taking with it iiap I3 and tongue I4. Thereupon the ball l5 may be removed from groove 8 and all of the parts properly cleaned and the device then reassembled.

From the foregoing description it will be readily seen that I have produced such a device as substantially ullls the objects of the invention as set forth herein.

While this specication sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not forro a departure from the spirit of the invention, as den'ed by the appended claims. p

Having thus described my invention, what-I claim as new and useful and desire to secure by Letters Patent is:

1. In a dispenser cap having a pouring opening therethrough, a flap normally closing said opening, the cap having an upwardly opening elongated groove therein extending diametrally from adjacent said opening, a closure plate on the 'cap aesinet and enclosing the groove adjacent the top there# of, said plate having a transverse slot therein adjacent said opening, a tongue on said nap proopening, the cap having a groove therein adjacent said opening, a ball normally disposed in said groove adjacent one end thereof, and means `mounting said flap for movement awaya from said opening, saidl means including an actuating element projecting into the groove adjacent its other end and positioned to be engaged and moved bysaid ball upon tilting of the cap and rolling movement of the ball toward said other .end of the groove, the cap being formed with a bleed hole therethrough from the groove, and the ball when disposed in said one end of the groove being seated on and closing said bleed hole.
