WATER BAG Filed March 18, 1936 INVENTOR Mm WMcfionAza A TORNEYS Patented Sept. 29, 1936 UNITED STATES PATENT OFFICE 7 Claims.

This invention relates to an improved water or ice bag and more particularly to the mouth and neck portions of such bags and the closure for the same.

The principal object of the invention is to provide a construction which will facilitate the filling and closure of the bag with greater ease and security than with prior constructions.

Other and further objects residing in the details of construction will be apparent from the following specification and claims.

In the accompanying drawing which illustrates one embodiment of the invention:

Fig. 1 is a perspective view showing the closure in released position;

Fig. 2 is a perspective view showing the closure in clamped or closing position;

Fig. 3 is a fragmentary view in vertical section of the neck portion of the bottle, with certain parts removed to better show the construction of the closing members; and

Fig. 4 is a front view, with parts broken away, showing a modified form of neck construction.

Referring to the drawing; the bag or bottle is constructed of molded rubber and is shown in part at I. It is formed with a neck 2 constructed in substantially fiat form, as shown in Fig. 1. This neck is formed by two wide and approximately straight, flat walls, connected at their ends. These walls are molded in the substantially fiat form shown and their connecting ends are slightly less in thickness. The arrangement is such that the inner faces of the walls 3 of the neck intersect with relatively sharp creases 5 in the rubber. These creases predetermine the points at which the neck will start to bend when pressure is applied to the ends thereof. Such construction is also important as insuring a tight closure because, when the walls 3 or their terminal lips 6 are pressed together, as shown in Fig. 2, the seam of the closure appears as one straight line devoid of the small fillets at the ends of the seam which would otherwise be formed by the distortion of the rubber as the walls are 5 pressed together and which might possibly permit leakage. The front lip 6 is preferably somewhat larger than the rear lip and has enough resiliency to restore the walls of the neck to the positions shown in Fig. 1, after pressure on the 50 ends of the neck is relaxed, as shown. This front lip also cooperates with the clamping device as will later appear.

For pressing the lips of the bag together to close the neck thereof, a clamping device of a 55 toggle-like nature is used. This device includes a bail-like member of wire, having a central straight portion 8 forming one jaw of the toggle clamp and pivotally mounted in a lug 9, formed centrally on the rear wall 3 of neck 2; two side bars it one at each end of and at right angles to the portion 6 and forming one pair of toggle links; and trunnions I l bent inwardly, one from the end of and at right angles to each side bar ID. This bail member, except for the trunnions l l and the central part of the portion 8 which passes through 10 lug 9, is encased by two rubber tubes [2. These tubes have been omitted in Fig. 3 but they appear in the other figures. The other member of the clamp is also formed of wire bent up in the form of a bell crank, having pairs of laterally spaced 15 arm l3 and I4. Each arm i3 is interconnected with the corresponding arm M by a loop l5 and these loops afford eyes to pivotally receive the trunnions H. The arms M which form the other pair of toggle links, have at their outer ends in- 20 turned trunnions I6 which rotatably support a metal roll I! which forms the other jaw of the toggle clamp. The outer ends of the arms l3 are interconnected by a cross bar or handle portion IS. The parts l3, l5 and H! are also encased, in 25 this case in a sheet of rubber l9 which extends between the parts l3 and beyond the handle part It, forming a flap 2% which is convenient to grasp when the clamping device is in the position shown in Fig. 2, as a means to release the device,-the 30 part l8 then being tightly pressed against the front wall 3 of the neck 2 as shown in Fig. 2.

Another desirable feature of the invention is shown in Fig. 4. This feature consists of a skirtlike part 2| which extends entirely around the 35 neck 2 and is suitably secured at its upper end thereto, as by cementing or by the tension of the beading 22. This part 2! extends downwardly like a skirt to enclose the upper part of bag l The part 2| may be used as a shield to protect 4,0 the hand of the user while filling the bag. At such time, the user grasps the neck of the bag in one hand and presses against the ends of the neck to dilate the opening 4 and the skirt-like shield may then cover and protect the hand. Alternatively, this part 2! may be upturned, as indicated in dotted lines, to serve also as a filling spout,the clamping device being then swung upwardly into a more or less vertical position against the back wall of the spout.

The operation will next be described. To fill the bag the opening 4 is dilated and this may be conveniently effected by grasping the neck 2 in one hand and pressing the two ends toward one another, thereby spreading the walls 3 apart.

The thinner ends and the creases insure that the bending starts along predetermined lines (those of the creases) rather than haphazardly. The side walls 3 are predisposed to bulge outwardly on the application of endwise pressure. A large opening is then available which will readily receive ice cubes if desired. The clamping device will at this time be positioned as shown in Fig. 1 and, as there shown, the bell crank l3, I l is swung rearwardly on its bail connection well away from the neck of the bag, allowing full and free access to the opening 3 for filling. In the filling of the bag, the user may upturn the member 2i and use it as a funnel or he may leave it in its downturned position to function simply as a shield to cover and protect the users hand.

Having filled the bag, the user relaxes the pressure exerted on the ends of the bag and the walls 3 then spring back into the position shown in Fig. 1, in which the opening 4 is nearly closed. The user still holds the bag, one hand grasping it by the neck near the lower end thereof. Then with the other hand he grasps the bar is of the clamping device and swings it from the position shown in Fig. 1 to that shown in Fig. 3. The bar I8 is now pressed downwardly and, in the initial stage of its downward movement, the bell crank will turn on the trunnions l l and the roll I! will easily move in under the shoulder 22 of the front lip 6. The roll is now positioned in contact with the front wall 3 and with the shoulder 22' and it remains thus positioned during the second stage of the downward movement of the bell crank. The arm i8 is pressed downwardly until it is arrested by engagement with the front wall 3. During the second stage of movement of the bell crank, the arms l3 swing upwardly and the sides IU of the bail swing downwardly until these parts l3 and ll! come into line and the roll ll and bar 8 are drawn together and pressure is applied in a toggle-like manner to squeeze the front and rear walls 3 tightly together and close the opening 4. In the final stage of the downward movement of bar l8, the parts l3 swing slightly above the parts I0, as shown in Fig. 2, crossing centers, and the clamp is then held in closed position by the abutment of bar l8 or its covering member H3 with wall 3. When it is desired to release the clamp one swings the cross bar l8 upwardly and this may be done conveniently through the fiap 2B attached thereto. Then bar i8 is swung up and over and across the mouth of the bag and back into the position shown in Fig. 1.

Thus. I have provided a water bag having constructional features of improvement associated with the filling neck thereof to provide for the convenient opening and closing thereof and facilitate filling and provide an effective leakproof closure.
