RECEPTACLE Filed Dec. 4, 1959 Patented Nov. 12, 1940 PATENT OFFICE RECEPTAOLE Matt. D. Schick, Chicago, Ill., assignor, by mesne assignments, to Fabart Instrument Company, Chicago, Ill., a corporation of Illinois Application December 4, 1939, Serial No. 307,353

6 Claims.

The invention relates to improvements in receptacles for liquids, granular and pulverulent products and has for its particular objects to provide a receptacle, such as a bottle, with a closure cap capable of limited movementl relatively to the receptacle from its sealing position to a positionwherein the receptacle contents may be discharged through an opening or openings in the peripheral wall of the cap which become positioned for such discharge when the cap is disposed at the upper limit of its movement, the structure' including a single gasket of suitable material disposed about the portion of the receptacle embraced by the cap and which maintains a seal between the latter and said lastnamed portion of the receptacle, when the cap is in discharge position for preventing leakage of contents of the receptacle between the skirt of the cap and said last-named receptacle when the cap is in its discharge position.

A further object of the invention is to provide `a structure of the above-mentioned type wherein the upper end portion of the gasket, functioning as aforesaid, also cooperates with the crown of 25 the cap to seal the receptacle when the cap is disposed at the lower limit of its movement.

. Another object of the invention is to provide a structure of the type comprehended by the foregoing paragraphs wherein the upper end portion 3o of the gasket cooperates with the mouth of the receptacle to constitute a funnel for the back flow of product into the receptacle as the latter is restored to upright position from discharge position.

lli

The structure of Figs. 1 and 2 is exemplary of a receptacle for liquids, such as liquors, medicines, lotions and the like, the neck portion I of which is equipped with external conventional thread formations 2 and an annular bead 3 below the threads 2. The portion 4 of the neck I immediately adjacent to the mouth 5 is of smaller diameter than the threaded portion and is equipped with an annular groove li between its ends to receive the internal annular bead 'I of the gasket 8 `which embraces all of the neck portion 4 and projects to an appreciable height above fthe latter, the uppermost end portion of said gasket 8 being provided with an internal beveled edge 9 which acts as a funnel element to cause back flow of liquid into the bottle as the latter is restored to upright position following discharge of liquid from the bottle.

The closure cap IU is equipped with a lcrown -II which is devoid of openings and the skirt portion of which is equipped with suitable thread formations I2 for engagement with the threads of the bottle. The length of said skirt portion ofthe-cap is appreciably greater than the distance between the upper edge of the gasket 8 and the low edge of the annular bead 3, the lower extremity of the cap being equipped with an nwardlyprojecting annular flange I3 for cooperation with the bead 3 to limit the upward movement of the cap.

` Adjacent the crown of the cap, the skirt portion is equipped with a pair of diametrically opposed openings I4 of sufficiently small diameter to preg vent flow of liquid from one'of said openings wn'en the other thereof is closed, as by pressing a finger tip over the latter, the diameter of said openings to produce this effect being determinable, of course, by the degree of viscosity of the liquid to be contained in the receptacle- `The gasket 8 is normally of larger diameter (see Fig. '7) than the inner diameter of the cap in order that it may maintain an effective seal against `flow of liquid through the skirt portion of the cap.

' Thus the gasket 8 performs three distinct functions, viz; that last-mentioned, cooperation with the crown of the cap to seal the receptacle, and that of providing a funnel formation for the back-dow of liquid into the receptacle as previously described. It also functions, necessarily, to seal the openings I 4 when the cap is disposed at the lower limit of its movement and because of this, it is unnecessary to force `the cap down upon theV gasket to an appreciable degree to effecta hermetic seal. It is obvious also that when the cap is forced down upon the gasket to the degree which will exert an appreciable compression stress upon the latter, then by the resultng distortion of the gasket the latter will be further bulged outwardly about the neck portion 4 and will seal the openings I4 more effectively than otherwise and exert such frictional resistance to rotation of the cap as will prevent unsealing of the receptacle in transit and handling.

In place of the conventional thread formations of the cap and receptacle, the latter may be equipped with a relatively wide cylindrical bead I5, as shown in Figs. 3 and 4, which is received telescopically in the skirt portion I6 of the cap I'I. Said bead I5 may be provided with diametrically opposed grooves I8 having oppositely extending but parallel end portions I9 lying in planes perpendicular to the axis of the bead, and an inclined middle portion. The skirt I6 of the cap I'I is equipped with a pair of diametrically opposed inwardly extending projections 2 which engage in the respective grooves I8-I9, the length of the latter being such as to limit the rotation of the cap to a quarter of a revolution to raise and lower the same from and to sealing position, said groove functioning similarly to a bayonet joint groove. As also shown in Figs. 3 and 4, the cap I'I may be equipped With small perforations 2l for the discharge of granular or pulverulent products such as salt, face powder and the like, said structure being particularly adapted to contain products of the lastmentioned types which are hygroscopic.

Obviously, the cap of Figs. l and 2 may be provided with the perforations of the cap of Figs. 3 and 4 and vice versa; the openings I4 of the cap of Figs. l and 2 may be substituted for the perforations of the cap of Figs. 3 and 4.

As shown in Fig. 5, the annular bead 22 of the receptacle neck, which is relatively Wide, is devoid ofgrooves and the cylindrical skirt portion 23 of the cap 2d equipped with perforations 25 similar to those shown in Figs. 3 and 4, is provided with the inturned flange 26 for cooperation with the bead 22 to limit upward movement of the cap, the latter being pulled up and pushed down by the user of the receptacle which is adapted particularly to contain table-salt. The receptacle may be of a well known type having a bottomI refill opening sealed with a cork, or the like. The gasket 2l of said receptacle, which corresponds in construction above the bead 2l thereof with the portion of the structure above the threads of Figs. l and 2, acts both to seal the perforations 24 and to yieldingly resist movement of the cap from and to sealing position.

The gaskets shown in the several gures may be of composition best adapted for the receptacle contents with respect to chemical reaction thereon or affecting taste or odor of same.

Disks t may be disposed in the crowns of the caps as shown in Figs. 3 and 4 for heat insulation or other purposes, as desired.

In the structure of Fig. 6 the' gasket 29 is dis posed upon the receptacle neck 30 and the annular beard 3| of the cap 32 is forced over the same to sealing position, the said bead 3II being spaced from the lower edge of the gasket a distance substantially equal to the depth of the openings 33 in the peripheral wall of the cap adjacent its crown. In raising the cap to discharge position, the bead 3l cooperates with the lower edge of the gasket to limit the upward movement of the cap under ordinary conditions of use, the cap being removable for rellng the receptacle by exercise of sucient force to cause the said bead 3| to pass the said gasket. In the structure of Fig. 6 the gasket performs all of the functions hereinbefore enumerated plus that of acting as a stop formation.

In Fig. 7, the normal and preferred cross sectional shape of the gaskets shown in the several figures of the drawing is illustrated, the outer peripheral portion of said gasket being bulged so that the body thereof is of greatest thickness in alignment with the flange 34 thereof. Thus compression of the gasket due to radial pressure of the cap exerted thereon, causes the greatest pressure to be exerted on said flange S4 and displacement of material causes the upper edge of the gasket to become flared and its lower edge portion to bulge slightly below the bottom of the annular groove in the receptacle neck in instances wherein an open annular space exists between the skirt of the cap and the opposed portions of the receptacle neck as is necessitated by the bead 3I of the cap in Fig. 6.

The structures of Figs. 5 and 6 adapt themselves to receptacle necks of a variety of shapes in horizontal section since it is not required that the caps thereof be rotated to move said caps to and from discharge position.
