Oct. 6, 1936. R. E. DESCHNER SANITARY CLOSURE FOR RECEPTACLES CONTAINING POURABLE SUBSTANCES Filed Aug. 5, 1935 R/cwmaa 6 Disc/five INVENTOR Patent d Oct. 6, 1936 UNITED' STATES PATENT OFFICE SANITARY CLOSURE FOR RECEPTACLES CONTAINING POURABLE SUBSTANCES 15 Claims.

The present invention relates to improvements in sanitary closures for receptacles containing fluid and semi-fluid substances, of the character set forth in my co-pending application, Serial Number 1,886, filed January 15, 1935. In addition to carrying forth the objects enumerated in said application, still further objects of the present invention comprehend:

The provision of an improved one piece cap v which may be sealed to the top of a full container to assure the purchaser that he is receiving the original contents of said container; the provision of a container having a neck so shaped that it may be fitted with a one piece cap that, as it is being applied, will direct back into the container residue adhering to the neck of the container after pouring and will form an airtight seal once it is in place; the provision of a cap which after removal from a used container does not have moisture on any part of its outside surface; the provision of a cap which upon its application to a container having a cooperative capengaging part integralized therewith will more effectively revert to the container residue tending to cling to the neck of the container after pouring; and the provision of an improved article of manufacture both as a container and as a cap.

More specifically the invention pertains to the provision of a container provided with a neck, a barrier for temporarily obstructing drip occurring at the mouth of the neck after pouring, and a cap fittable over the barrier and having clearance between the inside wall of the cap and the walls of the neck whereby as the cap is manually applied to the barrier the drip will be entrapped and ultimately directed backwardly into the container.

Referring now to the drawing wherein are shown preferred and modified embodiments of the device- Fig. 1 is a vertical mid-sectional view through the cap and upper end or neck of the container.

Fig. 2 is a side elevation of the structure shown in Fig. 1. i

Fig. 3 is a part vertical section and part side elevation thru the cap and upper end of the container showing a modification of the cap.

Fig. 4 is a plan view of the structure shown in Fig. 3, a portion of the caps structure being broken away to show the relation of the walls of vthe container and cap.

Fig. 5 is a vertical mid-section thru the cap and upper end of the container showing the cap in a partly removed relation to the container and both somewhat additionally modified in their construction.

Fig. 6 is a section similar to that shown in Fig. 5 except that the cap is shown fully seated.

Figs. 7 and 8 are vertical mid-sections thru the cap and upper end of the container showing a snap-in-place type of cap.

Fig. 9 is a vertical mid-section thru the cap and upper end of the container showing a modified form of an all rubber cap including a check valve.

Figs. 10, 11 and 110. are still further vertical mid-sectional modified showings of my invention, and

Figs. 12, 13 and 14 show in vertical mid-section difierent steps in the application of the cap in actual practice when constructed as illustrated in Figs. 1 and 2.

My invention comprises a conventional form of container I having a tubular part or discharge neck 2, including a mouth 3, provided with a shoulder forming a barrier 4 circumscribing said neck in a more or less spaced relation to said mouth.

The barrier 4 is adapted to temporarily obstruct any drippage adhering to the mouth 3 after pouring, from flowing down the sides of the container I until the cap 5, presently to be described, is applied whereupon such drippage is entrapped and ultimately directed backwardly into the container.

The barrier 4 and tubular part 2 form with each other a right angle joint in Fig. 1. However, this barrier may be modified to include a ring 6 forming an obtuse angle with the neck as shown in Fig. 9 or, a ring I forming an acute angle with the neck, as shown in Figs. 5 and 6.

The barrier 4 may be still further modified to include a ring 9 forming with the neck an acute angle as shown in Figs. 7 and 8 and providing the ring 9 with an upstanding annular flange HI.

Describing in detail the cap 5 shown in Figs. 1 h

and 2, said cap comprises a dome and crown portion having a stopper part l5 which fits within the, mouth portion of the neck 2 of the bottle, and an outer skirt portion it having an outwardly directed annular flange I1 and terminating in a diametrically enlarged part or flange 18. In this form of the cap the parts I6 and I8 are true cylinders and the flange H which unites them extends at a right angle to them both; there being an annular clearance 20. between the outside surface of said neck and the inside surface of said skirt. A gasket l9 may be fitted within the flange l8 to rest upon the barrier 4 when the stop per is applied.

In Figs. 3 and 4 the tubular cap portion "a has a plurality of longitudinal outwardly directed ribs 20 formed thereon which overlie drainage passages 2| thru which the residue adhering to the neck is directed backwardly into the container while the cap is being replaced after a pouring operation. When the cap I is fully applied, as shown in Fig. 1, the annular clearance is is continued over the edge and down into the mouth of the bottle neck by reason of the annular groove 22 being rounded throughout its deeper portion as viewed in cross section, to correspond with the curved lip of the mouth of the bottle.

In Figs. 12, 13 and 14 are illustrated three advancing steps in the application of the cap I to the neck of the bottle, Fig. 14 showing the final step wherein liquid drippage pultaceous material 23 is being forced back into the neck of the bottle. Owing to the fact'that the skirt flange l8 fits with a working fit around the exterior of the annular barrier 4, as soon as the lower edge of said flange reaches said barrier it entraps any liquid film which may overlie the bottle neck after a pouring operation, and as-the cap is pushed farther on such liquid is forced back into the bottle neck as illustrated at 23 in Fig. 14. A similar action upon the liquid residue takes place when the cap shown in Figs. 3 and 4 is applied.

In Figs. and 6 an exteriorly tapered bottle neck 28 is furnished with a circumferential external barrier I having along the upper surface thereof an annular trough or sump 8. The cooperating cap 25 is frusto-conical and has along its lower edge the outwardly directed intermediate flange 26 and downwardly directed terminal flange 21, these flanges cooperating to form a cap portion which flts snugly over and around the barrier I when the cap is completely applied. The taper of this cap is the same as the external'taper of the bottle neck 28 to which it is applied. This form provides a relatively large passageway 28a for the liquid to pass thru, which, however, decreases in size as the cap moves down until it is practically nil when the cap is fully seated.

- Hence the complete seating of the cap will produce an efllcient cleaning of the exterior surface of the bottle neck.

In Figs. 7 and 8 the bottle neck 30 is furnished with an additionally modified annular barrier 9 having an upstanding peripheral lip Ill. Said lip surrounds the upper surfacepf said barrier which is so inclined as to deepen towards the axis of the bottle neck. The cooperating cap H has around its open end an inclined outwardly direct- 5 ed flange 3| which when the cap is forced into the fully applied position will snap from the position shown in Fig. 7 to the reversely inclined position of Fig. 8. In assuming the latter position said flange will force liquid residue out of the sump or trough 8 and cause it to be directed upwardly within the loosely fitting cap and thence around the bottle neck into the bottle. In this case the cap will preferably be made of waxed paper or thin celluloid. The natural position which the resilient flange 3| always takes when released is shown in Fig. '7. The troughs or sumps shown in Figs. 5 to 8, being inclined transversely and deepest next to the bottles neck, will find their greatest utility in dispensing thin liquids such as hair oil which would tend to run 08 from a horizontal shoulder.

Fig. 9 differs from Fig. 1 in that an all rubber cap is shown and the barrier 6 is provided with a downwardly directed bevel 32 which forms with the neck 33 of the bottle an obtuse angle as a,ose,171

already mentioned. The cap M is also modified to include a check valve 35 which is mounted in the stopper portion 38. A valve chamber 31 is provided for the valve, said chamber having an inner vent '38 and an outer vent 39. The latter vent is sufliciently large to admit the ball valve 3! when expanded to an extent readily possible owing to the elastic character of the cap. This valve controlled vent means may be desirable owing to the fact that in this form of the device there is an air tight flt between the barrier 6 and the skirt portion 40 of the cap. The stopper portion 38 serves the same purpose as the corresponding part shown in Fig. 1. The cap of Fig. 9 is slightly tapered toward its closed end.

In Fig. the bottle neck and the barrier therearound are the same in form as in Fig. 1 and are therefore lettered in the same way. However, lateral vents 42 are shown in Fig. 10 just above the barrier 4. The cap 43 of this form is shown made of sheet material having at its open end the outwardly directed annular flange l4 and the tubular terminal flange 45. An elastic gasket ll, angular in cross section, fits within these flanges.

In Fig. 11 a bottle neck structure 48 is shown having an externally screw threaded'barrier l! whereon screws a cap 50 similar in shape to that shown in Fig. 10. A distinct annular clearance II is shown within the applied cap.

In Fig. 11a the structure is substantially the same as that shown in Fig.11 except that the screw threaded connection I! is located between the deepest portion of the cap and the exterior of the outer end portion of the bottle neck and the threaded connection is sufliciently loose to permit the residual liquid to ooze back into the mouth of the container.
