Application June 10, 1953, Serial No. 360,767

6 Claims. (Cl. 22278) This invention relates to dispensing and more particularly to a dispensing closure for collapsible tubes. The invention contemplates the provision of a closure which may be conveniently attached to a collapsible tube by threaded engagement with the usual threaded neck provided thereon. The closure is intended to simulate a fanciful figure or head and is provided with a valve, portions of which form significant parts of the head.

Heretofore many types of closures for collapsible tubes have been developed and produced but many of these were relatively unsatisfactory due to difiiculty in cleaning, failure of mechanical parts, inconvenience in use etc. Furthermore many of these prior art devices were of such a nature as to merely constitute a fad or to provide eye appeal for the purpose of stimulating sales as a consequence of which such devices were often used for a relatively short time and discarded.

It is therefore an object of this invention to provide a dispensing closure for collapsible tubes which may be economically fabricated in mass production and which may be marketed independently of the tubes to which the closure is to be applied.

A further object of the invention is the provision of a dispensing closure for collapsible tubes which may be conveniently molded of rubber, plastic or other suitable material, which closure may simulate a fancifui figure or head.

A still further object of the invention is the provision of a dispensing closure for collapsible tubes and including a valve for closing a dispensing aperture, which valve is resiliently maintained in open or closed position.

Another object of the invention is the provision of a dispensing closure for collapsible tubes which closure simulates a fanciful figure or head and is provided with a valve for closing a dispensing aperture, portions of the valve constituting significant parts of the fanciful head.

A further object of the invention is the provision of a. dispensing closure for collapsible tubes which may be utilized for dispensing paste, liquid or granular material and which may be conveniently cleaned and sterilized when necessary.

A still further object of the invention is the provision of a dispensing closure for collapsible tubes simulating a fanciful figure or head, such closure being provided with a valve for closing a dispensing aperture, portions of the valve constituting significant parts of the head, the valve being actuated by engagement of the finger with the portion of the valve simulating the nose of the head and the closure further being of such configuration as to immediately appeal to children of tender age and older. 1

Further objects and advantages of the invention will be apparent from the following description taken in conjunction with the accompanying drawing wherein:

Fig. l is a longitudinal sectional view showing a dispensing closure constructed in accordance with this in- 2,739,737 Patented Mar. 27, 1956 vention attached to a collapsible tube and with the valve in position for closing the dispensing aperture;

Fig. 5 a sectional view on the line 5-5 of Fig. 2

and particularly showing the mounting of the valve; and- Fig. 6 a sectional view on theline 6-6 of Fig. 1 further showing the manner of attachment of the valve spring.

With continued reference to the drawing there is shown a dispensing closure constructed in accordance with this invention and comprising a generally hollow body 10 which may be conveniently molded in two parts of rubber, plastic or any other suitable material by conventional molding and fabricating processes. Obviously if desired, the closure of this invention may be made by processes other than molding, such as carving the same from a block of wood or other suitable material, but since such latter process would be'considerably more costly the molding process of manufacture is to be preferred.

The body 10 of the dispensing closure of this invention isvprovided with a hollow head portion 11 which is intended to simulate a fanciful head or figure, such as those currently appealing to and enjoyed by children. The head portion llrnay be provided at the top thereof with a portion 12 simulating'a hat or other headcovering and the lower portion of the head 11 is reduced to form a neck 13 provided with internal threads 14 for threadedly and detachably engaging thethreaded neck 15 of a collapsible tube 16; The neck 13 is provided with an outwardly and downwardly flared portion 17 for engaging the upper end 18 of the collapsible tube 16 and the the lips of the mouth portion of the figure or head, such simulated lips being of somewhat bulbous formation to present a ludicrous appearance.

In order to close the dispensing aperture 21 a valve 23 may be'provided which may. conveniently comprise a relatively fiat elongated lever 24 pivotally mounted in and extending through an aperture therein and embedded in the material of the-head 11 as, clearly-shown in Fig. 5. Securedto the outer-end of lever 24 is a valve member 27 which may take the form of a ball or which may be provided with any other desired configuration. When in closed position as shown in Fig. 1 the ball 27 is in intimate contact with the wall 22 surrounding the dispensing aperture 21 and effectively closes the aperture 21 to prevent flow of material therethrough from the passage 20.

The inner end of lever 24 is provided with a cam surface having lower portions 28 and 29 and a raised or high formit-y with theconfiguration-oftbe' remainderof-the fanciful head but in addition; to completing the appearance of such head the nose portion 31 accomplishes another function which willalso be presently described.

Disposed within the head 11 is an elongated curved spring 32 with a portion thereof extending beneath tabs or loops 33 formed integrally with the material of the head 11 with the adjacent end of the spring 32 being received in a socket 34. formed in the material of the head. Obviously, if desired, the's'pring 32 may be attached to the head 11 by any other suitable means such as screw threaded fasteners, driven or headed fasteners or a suitable adhesive. The opposite end' of spring 32 terminates. in a curved portion 35 engaging the cam surface onthe inner end of lever 24. As shown in Fig. l the end 35 of spring 32 is in engagment with the portion 28 of the cam surface and in this position resiliently urges the nose por-v tion 31 outwardly of the head 11 and consequently urges the ball 27 into engagement with the wall 22 surrounding dispensing aperture 21 to resiliently maintain the valve 23 in closed position.

When it is desired to open the valve 23 for dispensing purposes the nose portion 31 may be engaged by a finger 36 of the user and moved inwardly as shown in Fig. 2 at which time the end 35 of spring 32 will pass over the raised or high portion 30 of the cam surface and engage the other low portion 29' to resiliently maintain the valve 23 in open position as shown in Figs, 2 and 3.

At this time as shown in Fig. 3 the collapsible tube 16 may be grasped by the fingers 37 and thumb 38 of the user to squeeze the same and'force the contents 39 there: of through the neck of, the collapsible tube 16, the passage 20 of the dispensing closure 10 and out through the dispensing aperture 21 to be spread on a toothbrush or other implement 40. Upon dispensing the desired quantity of material 39 the valve 23 may be closed by engaging the ball 27 with the finger 36 and moving the ball inwardly toward the dispensing aperture 21 at which time, the end 35 of spring 32 will again pass over the raised or high portion 30 of the cam surface on the lever 24 and againengage the low portion 28 of the cam surface to resiliently maintain the valve 23 in closed position. This closing of the valve 23 by a more or less snap action will result in cutting ofi the stream of material flowing from the dispensing aperture 21 thereby providing a clean break in suchstream.

In order to facilitate assembly of the spring 32 and the valve member 23 with the dispensing closure of this invention, the same may be molded or otherwise formed in two parts'41 and42 .which'after assembly of thespring 32 and valve member 23'with: the halfportion 41 may be joined with the other half portion 42 by any suitable means such as an adhesive43 to complete fabrication of the device.

It will be seen that by the above described invention there has been provided a dispensing closure which ma be conveniently attached orremoved from a conventional collapsible tube, which closure presents an appearance pleasing to children and which also incorporates valve means for effectively closing a dispensing aperture. By way of providing a further appeal to children the valve member of the closure of this invention is operated by engagement of the users finger withthe nose of the fanciful head or figure and obviously a child would enjoy using this device thus efieptively encouraging the use of toothpaste or other dentifrice and the IilteQthereby promoting increasedhealth in thechild or other. person us-' ing the device.

It will be obvious to those skilled in the art that a s y be ma e he invent o i o dep r n from the spirit and s'eope thereof and therefore the invention is not limited by. that which isshown in the draw ing and descrih edlin the specificationfbut only as indicated in the appendedclaims.
