- freely foldable receptacle for liquids and solids, the receptacle being flexible throughout so that it may be folded into small space and shipped without danger of breakage.
A further object of the invention is to provide a paper receptacle which may be employed for the sale and distribution of milk or other material, thus avoiding danger of infection from unclean bottles or similarreceptacles which are ordinarily employed for the purpose, and which must be washed after use.
A still further object of the invention is to provide an improved paper receptacle, and to employ a closure of novel and simple but eflective construction which maybe readily inserted and locked in place after the receptacle has been filled.
With these and other objects in View, as willmore fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fullydescribed, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.
In the accompanying drawings :Figure 1 is a perspective view of a'flexible receptacle constructed in accordance with the invention. Fig. 2 is a sectional elevation of the same, showing one form of cap or closure which may be employed. Fig. 3 is a detail perspective view of the cap detached. Fig. 4 is a detail perspective view of the receptacle folded. I
Similar numerals of reference are employed to indicate corresponding arts throughout the several figures of the rawin s.
in carrying out the invention, the receptacle 10 is formed of aper or similar cheap material sufficiently exible throughout to permit folding within a very small space, so that large iantities of the receptacles may be shippefl at comparatively small expense. The receptacles are made of paper which has been treated with paraffin or other chemical material'torender it water proof, and in order to add to the stren th of the vessel, its upper face is contracted to form a neck 11, resembling somewhat the neck of an ordinary glass bottle. The paper is turned over at the top to form the mouth of the receptacle, and, also, to form a seating flange 12 against which the cap or cover 13 may engage.
The cap 13 is formed of paper, cardboard, or other suitable material, and is provided with a tab 14 that constitutes a hinge which is preferably inserted under the bent edge of the pa er, and fastened in place, the free edge 0 the cap being provided with a small string or cord 17 which may be grasped for the purpose of pulling the cap outward against the flanged or inturned edge of the paper after the receptacle has been filled,
and to empty the contents of the receptacle the cap may be forced inward to its initial position.
These receptacles may be made at very small cost, and after being used a. single time may be thrown away or destroyed, so that the danger of infection from unclean bottles in constant use is avoided.
While the receptacles are specially valuable for the sale and distribution of milk, they may, of course, be used for the reception of liquids or solids of any nature.
I claim 1. A liquid receptacle having a body portion and a contracted neck portion formed of flexible Water proof material capable of bein folded with its bottom and sides in para el planes, and a closure attached hingedly to the neck portion to hold the latter distended when in its operative position and capable ofbein folded to occupy a position in a plane para lel with the folded sides and bottom.
2. A liquid receptacle having a body portion and a contracted neck ortion formed of flexible water proof materia capable of being folded with its side and bottom portions in parallel lanes, the u per edge of the neck portion eing inwar ly turned to form a downwardly or inwardly facing shoulder,
"and a closure of ri 'd material fitting snugly in and adapted to old the neck portion distended when said closure is in its normal position, and being hingedly connected with the neck portion to fold in a plane parallel with said side and bottom portions.
3. A liquid receptacle having a body portion and a contracted neck portion formed of flexible water proof material capable of being foldedwith the side and bottom fporbeing hingedly connected with the neck portions in parallel planes, the upper edge 0 the I neck portion bein inturned to form a downwardly or inwardly facing shoulder, the intion to fold in a plane parallel with the sides and bottom portions.-
In testimony that I claim the foregoing as 15 wardly turned portion being spaced from the my own, I have hereto aflixed my signature adapted to hold the latter distended when in its operative position, said closure having a tongue to engage between the inturned portion and the ad acent surface of the neck and adjacent walls of the neck portion, and a rigid in the presence of two Witnesses.
