To all whom it may concern Be it known that I, THoMAs FEBERT, a subject of Great Britain and native of Canada, residing at Lancaster, in the county of Worcester and State of Massachusetts,have invented certain new and useful Improvements in Can and Bottle Tops, of which the following is a specification.

My invention relates to new and useful improvements in closures or tops for milk cans, milk bottles or other receptacles of a like character and my principal object is to provide a closure which will permit proper ventilation of the contents of the receptacle without exposing the same to dust or insects and thereby retain the contents in an absolutely sanitary condition.

Another object of the invention is to provide a closure for the above purpose which may be readily secured within the mouth of the receptacle and which when in position, will permit the dispensing of the contents thereof in quantities as desired by a simple operation of the closure.

Another object of the invention is to provide the closure with an attaching means and means carried upon the closure for ventilating the contents in the manner set forth; and to fully seal the same from the outside atmosphere.

A still further object of the invention is to provide a device for the above purpose which may be readily detached from the receptacle by the proper persons for purposes of cleaning and which may be cheaply manufactured for universal use with receptacles in general and which while being cheap to manufacture, will not be likely to get out of working order.

The invention consists of certain other combinations and arrangements of parts, as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a portion of a can, preferably for containing milk, partly in section and showing my improved closure attached thereto. Fig. 2 is a top plan view of the closure. Fig. 3 is a similar view showing the ventilating plate in an open position. Fig. 4: is a plan view of the closure, open. Fig. 5 is a transverse sectional view taken on the line CD of Fig. 3 and looking in the directionindicated by the arrow. Fig. 6 is Specification of Letters Patent.

Application filed April 10, 1911.

Patented Mar. 19, 1912.

Serial No. 620,175.

a detailed side elevation of an arm employed in connection with the closure. Fig. 7 is a partial sectional view taken on the line A-B of Fig. 2. Fig. 8 is a side elevation of a bottle having a slightly modified closure construction. Fig. 9 is a plan view of a bowshapcd section of metal for retaining said closure within the bottle. Fig. 10 is a plan view of the closure. Fig. 11 is a similar view showing the ventilator open. Fig. 12 is a plan view of said closure open, with the ventilator also open and partly in section to disclose the securing means. Fig. 13 is a fragmentary sectional View taken on the line EF of Fig. 12.

Referring to the drawings in detail, wherein like referencecharacters designate similar parts throughout the several views, there is shown a milk can or other receptacle 1 having the usual reduced neck portion to which my improved closure is secured. This closure comprises a cylindrical sleeve 2 which is adapted to be secured in any desirable manner to the inner wall of the neck as shown in Fig. 1 of the drawing, said sleeve 2 being tapered as shown in Fig. 7 of the drawing and having an outwardly directed flange 3 at its upper portion which is adapted for engagement of a locking means carried by the cover plate 41. as will be hereinafter described. The sleeve 2 is open at its upper end and is provided with an extension 5 which is positioned over the usual handle for the receptacle in order to protect the same from injury therebeneath should the can be roughly handled and this extension 5 is formed with an opening therethrough adapted for the pivotal attachment of the cover plate lforming the closure proper, through the medium of a bolt or the like 6, which is also engaged through an opening in a keeper 7 forming an end section of one of the arms of the ventilator plate carrying member which is pivotally carried upon the cover plate 4;. The cover plate 4 and the collar 2 are cylindrical in form and said cover plate is formed with the imperforate keepers 8 forming the ends of the arm sections 9 also coacting with the keeper 7 and which are particularly shown in Fig. 7 and is attached or formed integral with said cover plate and having inwardly extended portions 10 provided with beveled under cut faces 11 adapted to frictionally receive the beveled ends 12 of each of the arms 9 and retain the same in locking engagement when moved to the po sition shown in Fig. 2 of the drawing. These keepers 8 are also provided or formed with outwardly directed hooked portions 13 which are extended under the annular flange 3 and provided with beveled faces 14; adapted to engage the beveled projections 15 formed on the under faces of said flange and spaced to receive each of said parts 13 of the keep ers 8, as is shown in Figs. 2, 3, and at of the drawing. As is also shown in Fig. 3, the cover plate 4 is provided with the beveled raised projections 15 beneath each of the keepers 8 so that as the arms are moved be neath said keepers, they will be tightly held against accidental disengagement therefrom and thus prevent the removal of'the circular caps 16 from over the screen openings 17 formed in the cover plate.

The construction of the screen openings is more particularly shown in Fig. 7, wherein the cover is provided .with said openings at suitable distances apart and in each are arranged the circular screens 18 secured in position by means of the rings 19. The arms 9 and the longer arm 20 which extend in opposite directions are joined to form a central enlargementi21 having an opening therethrough for the pivotal attachment of said arms to the cover plate 4t through the medium of a pin 22 and said longer arm 20 is formed with an end portion similar to the keepers 8 adapted to permit operation of all the arms in moving the plates over and off of the openings or screen covered ventilators, so as to let air in to the can without dust or insects getting therein. This keeper formed on the arm 20 also engages one of the beveled projections 15 formed on the under side of the flanged portion 3 so as to further assist in holding said parts in a closed position.

In the operation of using the can, the top is arranged in the manner shown in Fig. 4 of the drawing, and the collar 2 is secured to the can in any desirable way; -the can is then ready to receive the milk and after being filled, the plate is closed by swinging the arm 20 to the left in the position shown in Fig. 2, the four arm sections fitting against the keepers or end portions 7 and 8. Then it is desired to ventilate the contents of the bottle, the parts are moved to the position shown in Fig. 3, said circular caps 16 being disposed upon the arms for completely closing the same when in a locked position.

The application of the device to a bottle is shown in Fig. 8 of the drawing. Collar 2 is formed with a recess or groove 23 for receiving a bow-shaped spring 24: adapted to retain the closure within the neck of the bottle after the same is once placed therein,

this being due to the frictional contact of the spring with the usual reduced portion 25 formed in the neck of the bottle. The cover plate a is pivotally secured to the flange 8 at one edge by means of a pin 26 and said cover plate is further provided with a central opening which is covered by a screen 27 carried by the central portion of the arms 9 which are engaged at their center and adapted to be secured in position by the usual. hooked ends 13. In order to cover the screen openings 27, a plate 28 is pivotally attached at 29 and formed with a rounded edge 30 adapted to permit proper pivotal movement thereof when moved to the locked position shown in Fig. 10 with the arm 20 and engaging the usual beveled projection 15 formed upon the under surface of the flange 3. The arm 9 to which the plate 28 is pivotally attached, is provided with a raised portion 31 having a tapered or beveled edge 32 adapted to engage one edge of the plate as shown in Fig. 11 when moved sidewise to uncover the screen opening 27.

These covers may be applied to receptacles in general and may be easily removed by the proper persons for the purpose of cleaning before further use and setting away for the team to take to market, free from dust, dirt or insects. It is further apparent that the structure involves a few sections of. stamped or molded metal which obviously can be manufactured at a very nominal cost.

Having thus described my invention, what I claim is:

1. The combination with a receptacle; of a closure therefor, said closure comprising a flanged member secured thereto, a cover plate pivotally mounted thereon and having screen cover means therein, to permit ventilation of the contents of the receptacle, means for opening or closing the same as desired and means for locking said last named means in position.

2.
