This invention relates to liquid dispensers and more particularly to paper containers for milk.-
Among the objects of the invention is to separately dispense the cream from oil the top of the milk in the container.
Another object is to drain oil the cream without tilting the container.
Another object is to provide a self closing and self opening spout at the division line hetween the milk and cream in a paper container.
beneath. In the present invention the cream is withdrawn without disturbing the normal stratiiication.
Other objects and advantages will appear as the description progresses.
In this specification and the accompanying drawing the invention is disclosed in its preferred form. But it is to be understood that it is not limited to this formbecause it may be embodied in modifications within the spirit of the invention c as defined in the claim following the description.
In the one sheet of drawings:
Fig. l is a front elevation of v a conventional paper milk container having this invention applied thereto.
Fig. 2 is a fragmentary detail of the same showing the cream spout in operative condition, in front elevation.
Fig. 3 is a similar detail showing the same in side elevation.
In detail the construction illustrated in the drawing, referring first to Fig. 1, comprises the square type of paper container, the body of which is composed of a continuous sheet of wax impregnated card board 6, having its opposite ends t, overlapped or laminated and sealed together. This square or cylindrical body is closed at the bottom 3 and top 5 by discs of the same material clinched and sealed in the edges of the sheet forming the body.
The top is provided with a filling and pouring opening that is closed by the hinged flap t, which is attached to the top disc by a staple passing therethrough, in the usual manner. The inven outline through the overlying end 2, as at 5,
l0 and H, l2. The cutaway edges i3, N form a crescent shaped recess l5, into which the fingernail may enter to engage the edge H. The bottom. of the spout is outlined by the score lines i6, i1, I8, the latter converging toward the center of the top line ll. Because of the adhesion of the overlapping ends 2, 3, the lines 9-i2 may be a straight out instead of a perforation if desired.
When an outward pull is applied by the fingernail behind the line I4, the cut lines 9, in, II, If
give away and the body of the spout swings outward on the scored hinge 06, which opens the hole 1-. No cream flows out because it is airlocked in the top of the container. The sides I9, 20 are now bent inward on the score lines ll, l8 to form the spout, as shown in Fig. 2. The normal tension of the material of the container at the hinge l6, urges the upper ends of the sides 19, 20 against the exposed plane of the end 3 to maintain the spout in its open position at a declining angle.
The desired quantity of cream is withdrawn through the outlet 1 and pours down the spout, when the flap 6 is lifted to break the air lock in the top of the container. The flow stops when the flap is closed. The spout can be reformed into its original collapsed condition to close the hole I to protect the contents against contamination until more cream is desired.
If skimmed milk is desired all the cream is withdrawn as described and the outlet l closed. The flap 6 is then opened and the contents poured from. the container in the usual manner.
The offset cutting of the end 3 as indicated by the dotted line is wholly in the interest of economy in fabrication of the container for this invention. The cut-away portion below the lower half of the end 3', forms the top portion of the succeeding blank, without waste.
If it is preferred to locate the invention on the side or a panel of the container, away from the seam of the overlapped ends, a piece of the material may be adhered to the back of the chosen panel before folding, to perform the function of the double thickness indicated in Fig. 3.
Having thus described this invention what is claimed and desired to secure by Letters Patent is:
A container for liquids, composed of sheet material having overlapping ends on the body portion with a side outlet through the innermost of said ends; a spout having a bottom and sides formed from the material of the outermost of said ends and having a fold line defining an integral hinge beneath said outlet, the side portions of said spout being integrally connected to the body thereof along upwardly extending spaced fold lines, the end edge of each side portion adjacent the hinge line extending outwardly and making an angle with its respective fold line greater than 90 degrees, said end edges in operative position bearing against the plane of said innermost end for substantially the height of said outlet; whereby the bottom of said spout when open is main- 10 tained at an angle below said outlet.
