March 20, 1951 w. WILKINS COLLAPSIBLE DISPENSING SPOUT Filed July 19, 1948 INVENTOR.

WWW FM Patented Mar. 20, 1951 UNITED Glaims't (Cl. 222528) This invention relates to a collapsible spout forattachment to the side" of a cardboard or f d 'c'afdbo'afd container: I y

The" primary object of this invention is to provices-e61 aps'ible'spoutforattachment to a board container wnereby the" liquid in the 661itainer can be poured effectively from the side of the container instead of from the top thereof as is conventionally done with the usual milk container.

Another object of this invention is to provide a collapsible spout for attachment to a waxed cardboard milk or beverage container which is provided with a flap which when manually operated would simultaneously open the spout and produce a pouring opening above said spout.

Another object of this invention is to provide a collapsible spout which is wholly formed of a unitary piece of cardboard or wax paper properly cut and folded thereby making it possible to produce a large number of the spouts cheaply and quickly.

These, together with various ancillary objects and features of the invention which will later become apparent as the following description proceeds, are attained by the device, a preferred embodiment of which has been illustrated by way of example only in the accompanying drawings, wherein:

Figure 1 is a fragmentary perspective view of the spout as attached to a container in closed position;

Figure 2 is a view similar to Figure 1 showing the spout in a partially open position;

Figure 3 is another view similar to that shown in Figurel with its spout in a completely open position;

Figure 4 is a longitudinal sectional view taken substantially in the plane of section line 4-4 of Figure 3; F

Figure 5 is a transverse sectional view taken substantially in the plane of section line 55 of Figure 6;

Figure 6 is a longitudinal sectional view similar to that shown in Figure 4 illustrating the spout in closed position;

Figure 7 is a front elevational view of the spout mechanism with the spout base removed; and

Figure 8 is a top plan view of the unitary sheet of cardboard employed to make the spout.

Specific reference is now made to the drawings. In the several views in the accompanying drawings and in the following specification reference characters indicate corresponding elements throughout.

, 2.. maimedgenerally at It!" is a; cor'itainr'liaw rectanguiar" in shape" having a substantially" U" shaped slit ['8 thereon to which" is suitably se cured a tab 2|] which when pulled upwardly provides a pouring opening 22 in the side wall l2 of the container l0.

, Pivotally secured to the end wall I6 is a spout flap 24. Secured to the flap 24, by means of pasting or the like, is a base member 28 to which is secured a pair of spaced parallel side members 30 and 32, which are preferably right-triangular in shape and which are additionally provided with folds 34, so that when the flap 24 is moved upwardly, the side members 30 and 32 fold inwardly at the folds 34 in overlapped relationship as shown more clearly in Figure 7.

It should be noted that the Web portion of the slit [8 is adjacent the pivotal attachment of the flap 24 to the end wall I6 that the flap door 36 formed by the slit when urged into an open position by pulling upwardly on tab 20 will simultaneously unfold the side members 30 and 32 urging the spout flap 24 into an open position and displaying the pouring opening 22 thereabove.

It should be noted from Figure 8 that by merely cutting along the lines 38 and 40 and all the full lines connected to the lines 38 and 40, bending along the dotted lines 42 and 44 at right angles and in opposite directions, and then bending the fold 34 inwardly, the spout made of the unitary cardboard shown in Figure 8 may be configurated to take the form shown more clearly in Figures 2 and 3. The spout flap 24 may, if desired, be simply a cut out of the container itself bent downwardly along the fold 46 upon which the base 28 of the spout shown in Figure 8 may be suitably pasted as mentioned hereinabove.

In view of the foregoing description taken in conjunction with the accompanying drawings it .is believed that a clear understanding of the Having described the claimed as new is:

1. A collapsible dispensing spout for a container comprising an end wall, a spout, means for pivotally and foldably securing said spout to said end wall, said means including a pair of spaced side members inwardly foldable intermediate their ends, said side members including triangular members which overlap each other when in a folded position, said last-mentioned means including a door flap upwardly foldable upon said end Wall, and means for raising the door flap whereby the side members are extended and a pouring opening is simultaneously formed in said end wall above and proximate to said spout.

2. The combination of claim 1 wherein said raising means includes a tab secured to said door flap.

3. A collapsible dispensing spout for a container comprising an end wall, a spout, ,means for pivotally and foldably securing said spout to said end wall, and means pivoted to said end wall for simultaneously opening said spout and providing an outlet in said container, said lastmentioned means including a door fiap upwardly invention, what is foldable upon said end wall, and means for raising said flap to open said spout and simultane ously provide a pouring outlet in said end wall.

4. The combination of claim 3 wherein said raising means includes a tab secured to said door flap.

5. The combination of claim 4' wherein said first-mentioned means includes a pair of spaced side members inwardly foldable intermediate their ends.

6. The combination of claim 5 wherein said side members including substantially triangular members which overlap each other when in a folded position.
