BOTTLE CLOSURE MEANS Filed April 24, 1946 l N V EN TOR. law/@1206 flammne Yo any Jim c 217 Patented Aug. 9, 1949 UN IT ED STATES fPATENT OFFICE 6 Claims.

l :This invention relates to bottle closure means and particularly to closure'means that is readily applicable to and removable from the top of a bottle and that will make itv possible to pour liquid from a bottle without letting the-liquid thus poured come in contact with the top ofthe bottle.

This closure'meansis particularly welladapted for use on milk bottles but it will be understood that it may be used on other types of containers.

Another object is to provide a pouringattachment particularlynwell adapted to be used one milk bottle but which may. also be made .to fit other bottles from which-liquids are to be poured, said pouring attachment being, madecf-adurable material and being applicable tomilkbottles and the like after the usual disposable caps or closures are removed; therefrom.

Another object is to providea pouring attachment having a closure member that .JWi'u .be opened by the pressure of the liquid being poured and that will close assoon as the bottle or container is tilted intoan uprightpositionand: that a will prevent dripping of the liquid after pouring.

A further object is to provide a pouringattachment having a spout that extends upwardly and sidewise when the bottleis in an. upright position so that any liquid left-in the spoutafter pouring will always tend to drain back into. the

bottle and that further has a swinging closure:

member provided with an outer part thatcloses against and over thespout and an inner; part that swings inside of the spout and forms-a second seal and wiper member towipe or push-back into the container substantially all liquid that tends to adhere to the spout after pouring.

Another object. is to provide-a pouring attachment having a swinging closure member and having an air vent opening or vacuum relief port and having a sliding valve member operated: b the Fig. 2 is a sectional vi w of the same-taken on. I

Like reference numerals designate like parts throughout the several views.

The'drawings show a pouring attachment for a bottle which may be a milkbottle 3B of the type shown in Figs. 2, 4 and 5 or another typeof bottle 3| as shown in Fig. 6.

The device shown in Figs. 1 to' 4 inclusive comprises-a metal tube 32 of the proper size to fit snugly within the neck of the bottlel). An ex- :curved and upwardly inclined bottom wall 35 over .which the liquid flows. A cap or cover'Bfi is a permanently secured to the top of the tube 32.

A portion of the. cap 36 overhangs the pouring spoutand is curved'downwardly and inwardly to provide amember 31 for interlocking pivotal engagement with a curved upper end portion 3s ofa closure member. The closure member is formed of two parts39 and'c. The outermost part3!) has marginal flanges 39 that extend over the side walls 34 and bottom'35 when the member'39 is closed against the edges of said side wallets and bottom 35. Preferably a gasket fis is provided in member 39 to seat against the edges of

walls

34 and 35.

The inner closure member lfl moves in very close proximity t the side walls 3% and curved .wall 35 andwill push or wipe liquid back into the bottle in case any liquid tends to adhere

tothe Walls

34 or 35 after pouring. The two members 39 .and' lfi provide a double seal for closing the pouring spout.

A flat spring ll, pivotally mounted, by a rivet 42, on the cap 36 has a curved end portion- 43 adapted to rest on the closure member 39 and hold said closure member closed when thespring "4! is in the position shown by full lines in Figs.

1 and. 2. When the spring 4| is turned into a position as shown by dot and dash lines in Fig.1,

'it will release the member 39.

To relieve vacuum, which might hamper pourin from the bottle I preferably provide a vent opening 44 in the cover 36 and provide a plate 45 slidablein a guide 136 to cover and uncover the vent opening-44. The forward end .cf'theplate member 45 is pivotally connected with the

closure members

39 and 40. When the

closure members

39 and 40 are in a closed position the slide member 45 will cover the opening 44. When closure members 39 and ll) are moved to an open position the slide member 45 will be automatically moved thereby to uncover the opening 44. Thus automatically the vacuum will be relieved when pouring and the vacuum relief vent will be closed when not pouring.

The pouring attachment shown in Figs. 1 to 4 can be kept in the kitchen for use on milk bottles from which the usual caps have been removed. This device is quickly and easily applied to a bottle and will effectively protect the liquid within the bottle. When the bottle is tilted for pouring, pressure of the liquid against the member 40 automatically opens the closure member. The liquid pours from the spout easily and smoothly and the liquid can not come in contact with the top of the bottle. When the bottle is returned to an upright position the closure member will close by gravity, and in closing, the member 49 will push all surplus liquid back into the bottle so that there will not be any liquid drip from the spout.

The pouring attachment shown in Fig. 5 is similar to the pouring attachment shown in Figs. 1 to 4 except that in the structure shown in Fig. 5 additional weight 4! has been added to the closure member to make the closing of the same by gravity more positive and certain. Also in Fig. 5 the vacuum relief vent and closure means therefor and the spring for holding the closure means closed are omitted. Parts in Fig. 5 which correspond to similar parts in Figs. 1 to 4 are similarl numbered.

The pouring attachment shown in Fig. 6 comprises a tubular member 48 of inverted L shape which functions in a manner similar to the tube 32 and cover 36 of Figs. 1 to 4 and which is provided with a weighted closure device having an outer member 49 and an inner member 50. The

, tubular member 48 is of a size and shape to snugly fit within the neck portion of the bottle 3|.

The operation of the devices of Figs. 5 and 6 is similar to the operation of the device shown in Figs. 1 and 4.

The foregoing description and accompanying drawings clearly disclose preferred forms of my invention but it will be understood that these disclosures are merely illustrative and that changes may be made within the scope and spirit of the following claims.

I claim:

1. A pouring attachment for a bottle comprising a tubular member adapted to fit snugly within the neck portion of the bottle; a pouring spout on the tubular member above the top of the bottle, said pouring spout having parallel side walls and having a curved bottom wall that is inclined upwardly and outwardly from the bottle when the bottle is in an upright position; a swingingly mounted closure member operable to close against said spout; and a wiper member carried by said closure member and positioned in divergent relation to said closure member whereby said wiper member will be positioned substantially flush with the inner end portion of said spout when the bottle is in an upright position and will be moved outwardly clear of said spout when the bottle is tilted into a pouring position, said wiper member having its edge portions movable in close proximity to the side walls and bottom wall of said spout to push liquid that adheres to said spout back into the bottle when the bottle is moved from a, pouring position back to an upright position.

2. The apparatus as claimed in claim 1 in which interfitting hook shaped portions are provided on the upper portion of the tubular member and the upper edge portion of the closure member to form a pivotal suspension for the closure member.

3. A pouring attachment for a bottle comprising a tubular member adapted to fit within the neck portion of a bottle and extend outwardly therefrom; a pouring spout on said tubular member above the bottle; a swinging closure member for said spout; pivot means in the upper portion of said spout swingingly supporting said closure member; a wiper member carried by said closure member and swingingly movable into and out of said spout, the combined weight of said closure member and said wiper member providing gravity closure thereof when the bottle is in an upright position; and stop means adapted to limit the inward movement of said wiper member to a position substantially flush with the inner end portion of said spout.

4. A pouring attachment for a bottle comprising a tubular member adapted to fit within and protrude from the neck portion of the bottle; a pouring spout on said tubular member above the bottle; a swinging closure member for said spout; a wiper member rigid with said closure member and movable in said spout and having relatively close contact with the walls of said spout; a vacuum relief port in said tubular member; and means connected with said swinging closure member for opening and closing said vacuum relief port in response to swinging movement of said closure member.

5. A pouring attachment for a bottle comprising a tubular member adapted to fit snugly within the neck portion of the bottle; a pouring spout on the tubular member above the top of the bottle, said pouring spout having an inclined bottom wall which is inclined upwardly and outward y from the bottle when the bottle is in an upright position; a closure member supported for swinging movement relative to said spout; a wiper member carried. by said closure member swingingly movable within said spout, said wiper member being positioned to move outwardly clear of said spout to thereby leave the spout unobstructed when the bottle is moved from an upright position to an inclined pouring position and to move into said spout and wipe the inside walls of said spout and push liquid which adheres to said spout back into said bottle when the bottle is moved from an inclined pouring position to an upright position; and stop means adapted to limit the inward movement of said wiper member to a position substantially flush with the inner end portion of said spout, whereby said wiper member functions as a secondary closure member when the bottle is in an upright position.

6. A pouring attachment for a bottle comprising a tubular member adapted to fit snugly within the neck portion of the bottle; a pouring spout on the tubular member extending above the top of the bottle, said pouring spout having an inclined bottom wall which is inclined upwardly and outwardly from the bottle when the bottle is in an upright position; a closure member adapted to rest against the outer end portion of said spout when in bottle closing position; pivot means in the upper portion of said spout swingingly supporting said closure member; a wiper member rigid with said closure member and positioned in divergent relation thereto and swingingly movable in said spout with its edge portions in close proximity to the walls of the spout so that liquid on the inner walls of said poit will be pushed ahead of said wiper membe moves through said spout, said wiper member being positioned to move outwardly clear of said spout to thereb leave the spout unobstructed when the bottle is in an inclined pouring position and to move into said spout and push liquid which adheres to the inside walls of said spout back into said bottle when the bottle is moved from an inclined pouring position to an upright position; stop means adapted to limit the inward movement of said wiper member to a position substantially flush with the inner end portion of said spout whereby liquid is prevented from entering said spout ahead of said Wiper member; and a flat spring member pivotally connected with said pouring attachment and movable into and out of engagement with said closure member when said closure member is in closed position relative to said spout.
