ERIK A. PEARSON, F PORTLAND, QREGON KEEPING MILK AND SIMILAR SUBSTANCES OB, LIQUIDS COOL WHILE IN TRANSIT Application filed. December 5, 1927. Serial No. 237,920.

This invention relates to an arrangement for keeping milk and similar substances, or

liquids such as milk, cool in milk bottles or similar containers -While in transit from milk depots or creameries to consumers and until picked up by them for use.

The object of the invention is to provide the opening or mouth of the bottle or container with a receptacle made of a thin suitable material such as cardboard or paranine paper, the receptacle to have a lateral flange at the top,resting on the ledge in the mouth of the bottle and of a size to fit tightly within the flange or rim thereof and thus form a seal. After the milk in the bottle has cooled to ordinary temperature, the solid carbon dioxide is placed in the receptacle and a paper liner or cover in the form of a cup is placed over it. A paper closure disk is placed on top of the lateral flange of the receptacle and is also fitted snugly within the flange or rim of the mouth. As the ice melts the passes out from under the edge of lining and up along the sides of the receptacle and out 5 through a small hole or vent in the closure disk.

WVith the above and such other objects in View as may hereinafter more fully appear, I

have invented the device shown in the accompanying drawings, in which Figure 1 is a vertical section of bottle or container showing ice receptacle with closure disk. I

Figure 2 is a plan view of ice receptacle.

Figure 3 is a vertical section of ice receptacle.

. Figure 4 is an enlarged part of view shown in Figure 1, showing ice receptacle. closure disk and lining.

Like reference characters indicate like parts through out the following specification and in the several views in the drawings in which 1 indicates a milk bottle of the ordinary type, 2 is a receptacle of which the lateral flange 3 is resting on ledge 4 of the mouth of the bottle. The edge 5 of flange 3 is turned up slightly so that when closure disk 6 is placed on top of it, they will be pressed together and form a tight joint. 7 is a small hole or vent in closure disk 6 for the escape of the gas as the ice melts. 8 is a paperlining for the purpose of using the gas from the melting ice as a means for cooling the sides of the receptacle.

While I have shown the receptacle to be cup like receptacle having a lateral flange at the top of a size to fit within said flange or rim of the bottle and to rest on said ledge and a paper closure disk of a size to fit snugly within said flange or rim of the bottle so as to act as a closure for both the bottle and re ceptacle.

2. In combination an ordinary glass milk bottle having in the mouth thereof a ledge surrounded by an'upstanding flange or rim, a cup like receptacle having a lateral flange at the top of a size to fit within said flange or rim of the bottle and to rest on said ledge, said receptacle to have a cup like shaped lining resting on the bottom of the receptacle.

3. In combination an ordinary glass milk bottle having in the mouth thereof a ledge surrounded by an upstanding flange or rim, a cup like receptacle having a lateral flange at top of a size to fit within said flange or rim of the bottle and to rest on said ledge and a paper closure disk of a size to fit snugly within said flange or rim of the bottle, so as to act as a closure for both the bottle and receptacle, said paper closure disk to have a hole in about the center thereof as a vent for the escape of the gas.
