MILK OR COFFEE FLASK.

SPECIFICATION forming part of Letters Patent No. 325,806, dated September 8, 1885.

Application tiled February 24, 1885. Y (No model.)

T0 all whom, it may concern.-

Be it known that I, ABRAHAM ABRAHAMsoN, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements 'in Milk or` Coffee Flasks; and I do hereby'declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,and tothe letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in the construction of milk or coffee cans or flasks, and especially to those designed to be carried in the pocket of the user.

The main objects are to provide a construction whereby the can or iiask may be opened in a manner to expose and render its entire interior area readily accessible for the purpose of either cleaning out the same or for conveniently filling it wthoutthe aid of a funnel, and also to adapt the same vesselto be closed and sealed so long as may be required, and while in such condition to be emptied of its contents, as needed, by simply removing an ordinary screw or other stopper, so as to permit a discharge of the liquid without necessitating the opening` of the can',in the manner previously employed for washing and filling it.

To such end my invention consists i'n the matters hereinafter described, and particularly pointed out in the claims.

I In the drawings, Figure I is a vertical section through a can or iiask embodying the features of my invention. jFig. 2 is a side elevation of the same. Fig. 3 is an enlarged'verti cal section through the cover. Fig. 4 is a dei tail *perspective showing certain rigid bearings respectively belonging to the cover and the body of the can or fiask.

A represents thecan or ask as an entirety,

B being the body portion, and C the cover therefor. so far as its general shape is concerned, mod-V eled after a common or convenient form of iiat pocket-a'sk, the sectional outline of which is usually that of an elongated ellipse.

rlhe body B is closed at the bottom and open at the top, theentrance at the top end being practically equal to the sectional area of the body, ,so as to render the entire interior por- 'Ihe can or iiask herein shown is,l

tion of the body readily accessible when the cover is removed therefrom.

The coverlconsists of al iianged cap which is adapted to fit upon and close the top end of the can or ask body, and it is provided with an ordinary central discharge-aperture and a stopper therefor, the preferred construction being that of a threaded neck, D, surrounding the aperturc,and asmall sheet-metal cap, D, provided with the usual internal packing or washer, and adapted to be screwed down upon the threaded neck ornipple.

'Ihe cap or cover C is intended-to be drawn down and locked upon the can or ask body, and in order to provide between the two an air-tight joint one or the other, but preferably the cover, is provided with an elastic gasket or washer,E,secured to its inner or under side, and the body is provided with acontinuous single or double rib, F, arranged at its top end, -so that when the cap is tted upon the body the washer can be forced against the rib vor ribs,which press into the yielding material. The devices herein employed for locking the 'cap upon the can or ask bodyconsist of screws G, carried by one member as a fixture thereon, and designedto engage suitable bearings in or on the other member.

In Figs. l and 3 the screws are rotatablyy held in bearings in the cap, and extend down therefrom so as to permit them to enter bearings in or on the body portion of the can or ask at such times as the cap is applied to close the same. In Fig. 4 1the screws are shown permanently secured to and extending ,up-from the bearing part of the can-body, the cap in this instance being provided with apertures through which the screws may pass when the cap is closed. The knobs Gr2 in Figs. 1 and 3 are rigid with the screws and serve merely as `heads therefor; but in Fig. 4

the knobs orvheads will be adapted tot and turn upon the screws, so as to operate as `tightening-nuts, which may be turneddown against the ca p when applied, to the ends of the screws projecting above the latter.

The construction of the cap or cover 'with reference to either arrangement of screws is as follows: The ange C of the cap is made of suitable sheet metal, as is also the central portion, C2. These two comparatively slight and thin portions are united by a heavier and rocn rigid intermediate portion, C?, of some suitable cast'metal or metallic composition, which may be soldered or cast or otherwise secured to the adjacent sheet-metal portions, as preferred. The rigid portion C3 affords a rm, strong backing for the washer E, and also provides appropriate bearings for the fasteningscrews, whether the same are carried by the cap or the can-body.

The can or flask body is, like the flange of the cap, preferably composed of sheet metal, and is at its top end provided with an internal rigid ledge or ring, H, formed of cast metal or some suitable metallic composition, and either cast or soldered to the body. This ledge also affords substantial bearings for the screws, which, when carried by the cap or cover, may engage in threaded sockets H in the ledge when the cap is closed, yas in Fig. l, or which, whenv carried by the can or flask body, may be embedded at their lower ends in the material of the ledge, so as to be rigid therewith and stand up ready to receive lthe cap, as in Fig. Li. The ledge also acts in con junction with the washer E to form a tight joint when the cap is closed, for which purpose the rib or ribs F of the can or flask body are formed upon the ledge at a point back of the screws or the bearings therefor. The screws, when carried by the cap, are rotatively connected therewith, so as to prevent their being lost when the cap is removed from v the can-body, for which purpose each screw has a shoulder, G, countersunk in a recess in the under side of the rigid portion C, while the knob or screw-head Gr2 bears against the top side of the cap or cover.

rlhe washer E may be secured in any way to the under side of the cap; but the preferred mode is to ange the central portion, C2, of the cap, and extend the ange below the rigid portion G3, thus providing a lip which can be turned up against the under side of the washer.

The rigid portion C of the cap is rabbeted or cut away around its inner edge, so as to form in its under side a shoulder or continuous seat in which the washer will be securely held by the turned-up edge of the flange.

W'hen the cap or cover is fitted upon the can or Hask body and the screws tightened up, the washer E yields to Vthe ribs F, and thus permits the part C3 of the cap to seat upon the ledge H of the body when the ribs have been forced into the washer.

The cover is preferably provided with a continuous groove, C4, arranged in its under side and back of the washer or cushion E, this groove being opposite the single or double rib F of the can-body when the cover is fitted on the latter. The purpose of said groove is to provide space for accommodating a portion of the elastic washer` when the latter is pressed down upon the rib of the can or iask body.

Screw-cap D may be removed to permit the flask or can to be emptied of its contents; but

for filling or washing out the flask or can the main cap or cover C will preferably be removed.

Vhat I claim is- 1. rPhe combination, with a sheet-metal can or ilask body provided with an internal ledge of Ycast metal secured to the open top of the body, of a cover having a discharge-aperture and stopper therefor, and provided with a rigid portion, C3, opposed to the ledge when the parts are placed together, an elastic washer interposed between the rigid part of the cover and the ledge, and fastening-screws for holding the cover upon the body, substantially as described.
