This invention relates to a. closure for a water or icebag which is effected by constricting the neck of the bag by rolling or folding rolled or the folds.

An object of the invention is 'to provide compressing `means for v'the folds whereby 'they are constricted and drawn one against the other by thereof.

A further object of the invention is to provide separate elastic clamping tabs for each the clamping' tabs having acommon fastening plate with which they cooperate to compress the folds by tension applied at tension applied at the ends :the ends of the folds.

yihe invention consists in the features and the combination and arrangement of parts 29 hereinafter described and particularly point ed out in the claims.

in the accompanying drawings the rubber water bag l is provided with an elongated attened neck' 2 of substantial width for receiving either ice or water. The thicknessof the wall of the neck 2 varies in its longitudinal cross-section and is provided with thinned sections 3 and 4:, to establish predetermined lines of folding and facilitate the folding of the neck. rEhe thick portions are formed by vulcanizing'cross bands of elastic material integral with the neck, the thinned portions it over upon itself and holding it inv folded condition by compressing v the edges of the flattened portions. The tabs 'being the wall of the neck 4between the thick portions. The thinned section 4 is of greater area than the thinned section 3. At the base of the neck 2 a pair of elastic tabs 5 of rubber 'are connected to opposite sides thereof at are provided with openings 6 to-engage buttons 7 on a metal plate or stiifening member 8 and the tabs are provided with'openings 9 to cooperate with the key'portions l() on the ends o the plate 8.

The stiff plate 8 is adapted to be securely held in place a ainst the neck at the base thereof b the ta s 5. ln fastening the plate to the nec it is placed against the wall thereings6 and 9 in the elastic tabs are preferably so disposed with relation'to the plate that it is necessary to stretch the tabs in order to fasten them to the plate7 thus holding the plate securely under tension. Elasticity'in the neck contributes to the forming of an effective watertight closure since the tension in the tabs stretches the neck and brings the walls of the neckv forcibly together. With regard to opening and closing the neck, the plate is permanently held in place, there being no necessity of removing 1t. The removable function of the tabs 5 is incidental to the function of holding the plate permanently under tension.

A pair of long elastic rubber tabs 11 'are secured to the neck at the' thick portion between the thinned portions 3 and 4 and a pair of short elastic rubber tabs 11 are secured to the neck at the thick ortion above the thinned portion 3. Theta s 1l are each provided with two holes 6 as shown and the tabs 12 are each provided with one hole 6".

To operate the closure for the bag the section ais folded backwardly about the thinned' portion 3 and contacts with the rear face of plate 8 than tabs 11 are buttoned thereon, and thereafter the tabs 11 are successively buttoned over the buttons 7, one tab over the other. The closure is then complete, the folds a, b, and c of the neck bein compressed together by the action of the e astic tabs which exert a tension thereon by reason of the tabs being so designed that they must be stretched into engagement with the buttons. Also, as before stated, the neck itself being elastic materially aids in forming the watertight closure by stretching under tension of the tabs, so that the walls of the folded neck are forced tightly together.

The modification shown in Figs. 7 and 8 shows a pocket receiving section of elastic material open at its ends and provided with button holes 6 to receive the studs 7 ofl the metal plate and hold the said plate 8 in position at the base of the neck.

The compression of the folded neck by the elastic tabs and by its own elasticity effects a watertight closure.

The bag may be var readily and economically manufactured, t e entire bag and closure being molded simultaneously with one operation, the only assembly necessary being the securing of the metal strip stiifening member, which serves as the base or foundation against which the folds are drawn and com ressed by the tension of the elastic tabs.

T e tabs may be formed as extensions of cross bands vulcanized to the neck, these bands being spaced apart to leave the material of the neck proper uncovered as at 3, 4 to thus provide the predetermined lines of fold.

Instead of complete tabs being formed integral with the neck of the bag I may provide short extensions 13 Fig. 9 of the cross bands.

These extensions have slots 14 and a removable elastic strap or belt may be threaded through these slots to answer as tabs, and these may be renewed. I have found, however, that the permanent tabs are durable and will endure as long as the life of the bag.

Figs. lO and 11 show a further modification of the invention employing a plate 8i1 curved at its ends as at 15 to conform to the neck of the bag. A slot 16 is provided in each of these curved ends 15 to receive the rubber tabs 5. The elastic tabs have narrow portions 17 which may pass freely through the slots 16 and wide portions 18 which are wider than the slots so as to limit the movement of the tabs therethrough. When it is desired to lill the bag with ice the tabs 5a are unfastened from the metal plate and the plate is pulled away from the neck, the tabs slipping through its slots until stopped by the wide portions 18 of the tabs as shown in Fig. 11. This permits flexing of the neck wall to provide space for the passage of ice through the neck.

It will be noted (Fig. 6) that when the neck is in folded and closed position the tabs at pressing the folds in folded position, said i tension means connected to and applying its force to the opposite edges of the neck and in opposite directions transverse to the axis of the neck.
