MILK-CAN.

SPECIFICATION forming part of Letters Patent No. 632,556, dated september 5, 189e.

Application filed Api-i125, 1899.

To all whom t may concern/.-

Beit known that I, Roon; DURAND, 'a 'citizen of the United States, residing at Apple River, in the county of Polk and State of W'isconsin, have invented certain new and useful Improvements in Milk-Cans; and I do hereby de clare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is designed to construct a milk-can which will secure perfect ventilation at all times, provide an escape for gases and odors, shed water, and exclude the entrance of bugs, insects, dirt, mice, and other small animals. Moreover, the cover can be locked or sealed in any of the usual ways, so as to prevent tampering with the contents of the can, and the milk or cream will have free commnnication with the external air for ventilating and purifying purposes.

The improvement consists, primarily, of a Ventilating-channel formed between the neck of the can and cap, a corresponding channel between the flanges of said parts and in communication with the vertical channel, and a protected outlet in the flange of the can adapted to be covered by the iiange of the cap when the latter is in position.

The improvement also consists of the novel features, details of construction, and combinations of parts, which hereinafter will be more particularly set forth, illustrated, and finally claimed.

While the drawings show the preferred embodiment of the invention, it is to be understood that various changes in the form, proportion,and minor details of construction may be resorted to without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawings, Figure l is a perspective view of a milk-can having the invention applied thereto. Fig. 2 is a detail section of the cap and neck portion of the can, the vertical channels being in line with the protected outlets formed in the Iiange at the upper end of the can. Fig. 3 is a view similar to Fig. 2, the cap being turned so as to throw the vertical channels out of line with the protected outlets. Fig. 4 is a'detail view of, the neck Serial 110,714,402. (No model.)

portion of the can as seen from above. Fig. 5 is a detail perspective view of the cap inverted.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The can is of ordinary construction and com; prises the body l, neck 2, and flaring flange 3. Outlets 4 are provided in the flange 3 at diametrically opposite points and are protected by meshed fabric 5, consisting in the present instance of pieces of wire-gauze soldered to the iian ge adjacent to the edges of the outlets. The purpose of the meshed fabric or protector is to prevent insects, bugs, vermin, and the like from passing through the outlets 4 into the channel 6, formed between the anges of the cap and neck and at all times in communication with th'e outlets 4 and the interior of the can through the vertical channels 7.

The cap 8 for closing the neck of the can comprises a neck 9 and a flaring flange l0, the latter corresponding to the flare of the flange 3, so as to fit snugly thereagainst. The neck 9 is of a size to snugly iit within the neck 2 and is provided at opposite points with vertical channels 7. The channel 6 is of annular form and is located intermediate of the inner and outer edges of the flange lO and is in communication with the vertical channels 7 by means of extensions 1l thereof formed in the inner portion of the flange lO. Inasmuch as the cap is constructed of sheet metal, as tin, the

several channels

6, 7, and ll are formed by being pressed or spun in the respective parts, as clearly indicated in the drawings. It is contemplated Within the scope of the invention to form the channels is preferable to provide them in the manner set forth and illustrated. The outlets 4 are positioned so as to register with the annular channel 6, and since the vertical channels are at all times in communication with the annular channel it will be understood that it is not necessary to locate said vertical channels in any deiinite position in order to secure ventilation. This is clearly demonstrated in Figs. 2 and 3 of the attached drawings. The flange ll overlaps the iiange 3 and is of slightly-greater diametrical extent, so as to in the corresponding parts of the can but itV IOO she'd Water, snow, and the like and prevent entrance thereof into the can. W'hen the cap is in positione the several channels are closed at their outer sides by the subjacent portions of the can and constitute passages for the escape of Warm air and noxious odors and admit pure air into the can to replace that escaping, thereby preventing premature souring of the milk or cream and enabling it to be maintained in marketable form for a greater length of time than would be possible if no means of ventilation were provided.

Having thus described the invention,what is claimed as new isl. A milk-can having an outlet in its upper portion, a snug-fittingcap closing the milk can and outlet, and an annular air-passage having communication with the interior of the can and formed by a depressionin one of the subjacent portions of the cap and milkcan body and in communication with the said outlet at any and all relative horizontal adjustments of the cap, substantially as set forth.

2. A milk-can having an outlet in its upper portion protected by a meshed fabric, a cap closing the can and extending over the protected outlet, and an annular airpassage formed between subjacent portions of the cap and body portion of the can and at all times in communication with the said protected outlet and the interior of the can, as and for the purpose set forth.

3. A can provided with a neck portion having an outer-flange formedwith anoutlet, in combination with a cap comprising a neck and flange, the latter adapted to overlap the flange of the can-body, an annular channel formed in the flange of the cap at an intermediate point, and a vertical channel formed in the neck of said cap and in communication with the said annular channel, the several channels constituting ventilating or air passages, as and for the purpose set forth.

4. In combination, a can having a neck and an outwardly-flaring ange, the latter pro-r vided at opposite points with outlets protected by a ineshed fabric, a cap comprising a neck and flaring flange, the latter adapted to over.- lap the iiange of the can-body and to extend over the protected outlets formed therein, an annular channel formed in the ange 0f the cap ata point intermediate of its edges, and vertical channels in the neck of said ,Cap and in communication with the annular channel, said channels being adapted to be closed .at their outer sides bythe subjacentportions of the can-bod y and forming air and Ventilating passages, as and for the purpose set forth.

In testimony whereof I afx my signature in presence of two witnesses.
