CLARENCE L. COX, OF CLEVELAND, OHIO.

NON-REFILLABLE RECEPTACLE.

To all whom 2'25 may concern.

Beit known that l, CLARENCE L. Cox, a citizen of the United States. residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Non-Refillable Receptacles, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to liquid containers and has for its object the production of a device of this character which shall be absolutely proof against being refilled after having been emptied of the original charge ii'itroduced therein at the time of sealing. The advantages of such a container are obvious and such a device has been sought for many years. Many of the former containers have depended for their non-refillable character upon the necessity of breaking them to permit the withdrawal of the liquid originally contained therein. These devices have not received very favorable reception because of the consumers fear of the particles of glass liable to be contained in the liquid. Other devices have depended upon valves which should permit the withdrawal of the original contents but prevent the introduction of a new charge of liquid. These valves have either been inoperative from principle, or so complicated as to become inoperative through accidents, or so expensive as to be impossible of commercial use.

According to my invention, I provide a movable piston which can be moved for- .ward to expel the original contents of the receptacle but which cannot be moved back to its original position without first breaking the receptacle. In this way I avoid the objection raised to the method first above described since the receptacle is not broken in advance of withdrawing the contents therefrom, but must be broken, at least in part, before it can be refilled, and after such breaking it is either impossible to refill it, or impossible to impose it upon a purchaser.

Generally speaking, my invention may be defined as consisting of the combinations of elements recited in the claims hereto annexed and illustrated in the drawings accompanying and forming a part hereof, wherein:

condition for shipment; Fi 2 is a similar view illustrating the same in half emptied condition and showing the means for operating the same; Fig. 3 is a transverse cross sectional view taken substantially on the line 33 of F ig. 2 and looking upwardly; Fig. is a transverse cross sectional view taken on the line l l of Fig. 2 and looking down wardly; and Fig. 5 is a sectional detail view of a modified form of cover securing means.

Describing the parts by reference characters, my receptacle comprises a container 1 of cylindrical or prismatic shape, and preferably of circular cross section as shown, although a container of polygonal cross section could be employed without departing from the scope of my invention. The bottom of the container is closed as at 2, and leading from the bottom is a discharge duct or passageway 3 preferably terminating in a down-turned spout i. In the embodiment illustrated herein, this duct or passage Way is formed in a longitudinal rib or protuberance 5 formed integral with the side of the container, and the spout 4 is formed at the extreme upper end of the container, although both duct and spout might obviously be formed otherwise without departing from the scope of my invention. The duct 3 communicates with the interior of the receptacle through a port 6 formed in the bottom 2 and is preferably connected thereto by means of the oppositely extending transverse passage ways 7 and 8 connected by a sharp or abruptbend 9. The object of this construction will be later described. The upper end of the receptacle is preferably formed with an integral outwardly projecting lip 10 adapted for the reception of a cover member. This cover member consists of a circular metallic plate 12 having a down-turned annular flange 13 of approximately the same shape as the body 1 of the container and provided with a laterally projecting lip let similar to the lip 10. This cover member is also provided with a laterally extending shield 15 adapted to overlie the spout 4t and prevent injury thereto. The possibility of so protecting the spout is one of the chief reasons for continuing the duct- 3 clear to the top of the receptacle. In the embodiment illustrated in Figs. 1 and 2 this cover is secured to the receptacle by means of an annular clip 16 having inwardly extending ears adapted to embrace the outer Patented June 17,1913.

races or the lips l0 and ll and to compress them upon a gasket 1'? introduced therebetween. in order to prevent the. removal of this cover for traiu'lulent purposes, this clip is preterably b axed or welded thereto as shown at l8. Suitable packing material is 'ntroduced between the shield 1.5 and spent it as shown at 19.

The piston or ejecting member of my receptacle consists oi a metallic plate 21 shaped to lit snugly inside the body 1 thereol and to he slid therealong. and having an upwardly turned lateral rim Below this piston is introduced a iiat disk 23, pre;ter ab y oil ork, adapted for the immediate contact ot' the liquid, the rear edge of this disk being preferably recessed as at El tor the reception at a rubber ring or gasket :23. In order to permit the shifting of this piston to expel the liquid from the container, the cover plate 12 is formed witi a central, internally threaded boss adapted to receive an eloi'igated threaded push rod 29 provided with an operating wheel or handle by means of which the piston can be shoved to the very bottom of the container. in order to prevent. the retraction of the piston so as to aspirate a new charge of liquid into the container by way of the spout i, 1 provide the push rod 21) with a longitudinal groove 31 adapted to cooperate with a pawl 82 pivoted to the cover plate 12 and impelled thereagainst by means of a spring The cover plate 12 is illustrated as having an internal boss tori'ning a contimiation. of the boss 28 and provided with a slot 54; in its wall through which the pawl 32 extends. ll ith this construction it is obrious that tho withd 'awal of the push rod is impossilole unless the cover be first removed which would necessitate the breaking otthe body or else would be so expensive as to deter any person from making a practice of doing it. Furrhermore it impossible to relill the receptacle by introducing liquid under pressure through the spout l since the rearward movement oi? the piston is prerented by the push rod.

In the embodiment illustrated herein, the boss 98 is tormed with external threads and the piston. 21 is formed with an internally threaded boss St) adapted to engage therewith. The base at the boss 3G is formed with a socket 37 adapted to receire This socket is formed with internal threads of the same pitch as those in the boss. When the push rod is introduced therein it seats itselit against the bottom of the recess 3:3? and when the rod is further rotated the piston is revolved and unscrewed from the boss. The threads upon the exterior of the boss are oi": the same pitch as those upon the interior. This construction permits the push rod to operate as a key and prevents the bottle from being drawn upon by any person unless he employs a threaded instrument having the same pitch as the push rod. ()t

course it' the receptacle be of polygonal shape and the piston ther-etin'e non-rotatable,

he interlocking eature between the piston and cover either has to be omitted and the recess 37 made as a smooth socket or the size of the plate 21 decreased so as to permit its rotation. In case a designing person attempts to evade the non-refillable characte of the receptacle by eu'lploying an ungroored push rod he is met by another ditlicul y: when he witlulraws the smooth push rod he leaves the piston behind. And even though he gr: pples tor the piston, he can raise only the plate 21 since the disk 23 will remain behind. And it he tries to fill the bottle through the spout #1 by pressure after withdrawing his smooth red the friction between the rubber ring and the wall oil? the receptacle will be so great as to cause the receptacle to burstbet'ore the piston will more. In fitting up these recepta :lcs, the cork sheet 23 with its gasket 25 is introduced and then the piston 21 secured to the cover plate 12 as illustrated in Fig. l. The gasket 17 is applied at the same time and the clip 16 applied and irremovably attached to the core member. The liquid may either be introduced before the piston is applied or it may be applied later via the spout s in the latter case the air in the receptacle is prete ably first exhausted by means of an air pump. it plug or stopper 38 of cork or wax is preferably inserted in the spout l as shown in Fig. l.

The receptacles and push rods are preterably shipped separately both for the purpose of compactness and to prevent abstrac tion of the contents. Yr hen it is desired to withd 'aw the contents of the receptacle, the piston first unscrewed from its connection with the cover in the manner above described andv the liquid ejected as desired.

The outlet duct 3 is connected to the interior or the receptacle by means of the re rersely exteni'ling ducts 7 and 8 in order that it may be impossible to remove liquid from the receptacle by drilling a hole through the cover and afterward draining; or siphon- 111;: the contents away. .lfurthermore, the

abrupt bends in the duct and partiimlarly the bend S) i'naterially impede the introduction therethrougrh of a ll uiible Cl pillary pipe by means of which gas under pressure might be introduced so as to eject the liquid coniHlliS.

In F 5 l hare illustrz ted a modified and simplified expedient .tor securing the corer to the receptacle. In this View, the receptacle body 1 is shown as having an inwardly projecting lip it at its upper end, said lip forming the upper wall or a groove fl-l and being or a size to permit the introduction of apiston into the receptacle. The cover plate 12 is formed with the annular flange 13 and lip 1st as before, said lip terminating in a depending skirt 42 adapted to surround the upper end of the receptacle. Secured to the inner surface of the flange 13 are a plurality of resilientsnaps or hooks 13 adapted to engage beneath the lip 40 and hold the coversecurely in place. Obviously it would be totally impossible to remove this cap from the container without destroying one or the other.

lVhile I have described the pawl 32 as directly engaging the groove 31 formed in the sides of the push rod, it is obvious that, without departing from the scope of my invention and without serious change in construction, the pawl could be caused to engage a ratchet wheel slidably sleeved on the rod 29 and having a key or finger engaging the groove 31.

\Vhile I have necessarily described my invention in detail, I do not propose to be limited to such details, except as the same may be positively included in the claims hereto annexed or may be rendered necessary by the prior state of the art.
