NON-REFILLABLE BOTTLE.

Specification of Letters Patent. Application filed April 18, 1913.

Patented none 30, 1914. Serial No. 762,096.

To all "whomit may concern 7 Be it known that we, LOREN A. WI-IITING and Genre S. PARKER, citizens of the United States, residing at Hartford, inthe county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

Our invention relates toimprovements in non-refillable bottles, and'the object of our improvement is to produce a bottle having a'neck provided with a perforate plug of special formation" and an auxiliary cork whereby the said bottle is made non-refillable and at the same time can be manufactured by processes'that are ordinary and at moderate cost.

In the accompanying drawing :-Figure 1 is a side elevation of the neck and upper part of our non-refillable bottle. Fig. 2 is a plan view of the same. Fig. 3 is a sectional view on the line :0 w of Fig. 2, the outer cork being shown in broken lines. Fig. 4 is a side elevation, on an enlarged scale of the plug. Fig. 5 is a plan view of the same. Fig. 6 is a bottom view of the same. Fig. 7 is a sideelevation of a modification of the plug. Fig. 8 is a plan view of the same. Fig. 9 is a side elevation of the auxiliary cork or stopper.

Our non-refillable bottle comprises a body portion 10 of usual form and a neck 11 of special form.

The neck 11 that comprises an is elongated and has a bore outer portion 12 at the outer 'or upper end and an inner portion 18 that is positioned. between the said outer portion 12 and the body portion-1O of the bottle. 7

The side wal of the'outer portion 12 of the bore deviates slightly from the cylindrical, havinga slight taper from the extreme outer end inward the entire length or up to the junction 1 1 ofthe same with the inner portion 13, and is of sufiicient length to house therein aplug 15 at the lower end and adjacent the said junction 14 and the outside or main cork 16 at the outer end.

In some cases the main cork 16 may be seated on the plug 15.

The side wall of the lower portion 13 of the bore has a more appreciable taper than that of the upper portion 12, being decidedly conical, so that the extreme inner end 17 thereof is appreciably smaller in diameter than the diameter at'the junction 14:.

The main cork 16 serves as the ordinary iii closure of the bottle and is of itself ordinary.

The plug 15 has an outer wall to fit the side wall of the upper portion 12 of the bore and is provided with a plurality of ion gitudinal perforations in the form of channels in the periphery and of special formation. The said perforations comprise three parts, respectively an upper passage 18, a middle passage 19 and a lower passage 20. The said middle passage mon annular channel 19 which extends around the body portion of the plug 15 and at'about the middle portion thereof and which forms a common connecting means for the several upper passages passages 20.

The lower wall 29 of the channel 19 is plane and essentially annular between the 19 is part of a coin 131 18 and lower interruptions produced by the lower passages 20.

As shown there are three upper passages 18 spaced 120 degrees apart and three lower passages 20, also spaced 120 degrees apart and the said upper and lower passages 18 and 20 are positioned angularly theone between the other, or at an angular spacing around the axis of 60 degrees between an upper passage 18 and a lower passage 20. Furthermore, the passages 18 and 20 are made relatively narrow circumferentially iv and long in the axial direction, all with a view to making the three part passage composed of upper passage 18, intermediate or middle passage 19 and the lower passage 20,

circuitous and to render it exceedingly dlificult and practically impossible to force an implement or the end of a piece of wire admitted to any of the upper passages 18 through any of the lower passages 20 and into the lower portion 13 of the bore.

The upper end 21 of the plug 15 is finished off plane and is suitable for a seat for the main cork 16 and the lower end is provided at the center with a downwardly projecting lug 22, which as shown and preferably is rounded. v

In the lower portion 13 of the bore there is housed an auxiliary cork or stopper 2a.

The said auxiliary cork 2 1 is of appreciable cordingly, when the auxiliary cork 2i is positioned in the upper end of the said lower part 13, as when the cork is in contact with the lug 22, there is clearance around the side wall 25 of the stopper 24 which permits of free passage of liquid. The amount of such clearance or play provided for the stopper is not sufficient to permit the stopper to turn end for end so that the stopper will always be properly directed to seat itself in the lower end of the lower portion 13 of the bore when there is no flow of liquid outward and particularly, when there may be a flow of liquid in the reverse direction, as in case an attempt were made to re-fill the bottle.

The taper of the side wall 25 of the stopper 24,: and the side wall of the lower portion 13 of the bore is such that there will in no case be a binding engagement with one another, so that the auxiliary cork 24 will always be free and unseated in case of the slightest tendency to flow of liquid in the proper direction for pouring from the bottle. In the case of the plug 15 however, because of the slight taper of the side wall of the same and the side wall of the upper portion 12 of the bore with which it is engaged there will be a firm seating of the plug 15 as a. result of even a slight pres sure on the outer end thereof. By having the main cork 16 seated thereon, such a firm engagement of the plug 15 with the neck 11 is positively assured. Accordingly, the plug 15 after being once firmly seated in the neck 11 is practically permanently secured therein, and cannot be removed without damage to the plug itself.

In the modification shown in Figs. 7 and 8 only two upper-passages 18 and two lower passages 20 are shown, and these are somewhat larger than the passages 18 and 20. As described, the upper portion of the bore has a slight taper; the lower portion has a taper somewhat more abrupt; the two taper portions merge at a slight angle and at a. plane substantially tangential to the tip of the lug 22; the lower portion of the bore is of suitable length to permit of a movement of the auxiliary cork to provide for free outward flow of liquid; the relation of the length of the auxiliary cork and the taper thereof to th opposed walls of the lower taper portion are such as to prevent a binding engagement, either by a too firm a seating of the auxiliary cork at the inner position, as by a too moderate a. taper, or by being tilted at; the outer position in refilling, as with a too abrupt taper; the er p tion is of such length as to house the plug 15 and the main cork and without excess length; and the length of the outer portion, the, length of the inner portion, and the angularrelation of the tapered side walls of the said portions are such that a pocket or reservoir is avoided at the junction of the two tapered side walls, and thereby the collection of an appreciable quantity of liquid at the said junction is prevented, such as would tend to elevate the larg end of the auxiliary cork and to bind or cramp the auxiliary cork in the lower portion of the neck, particularly when the refilling operation is attempted with the bottle in an approximately horizontal position.

In order to meet the requirements mentioned, particularly to prevent re-filling when the neck is in an approximately horizontal position, we find the arrangement and construction of details shown to be particularly satisfactory and ell'ective,- and that a departure therefrom to any appreciable extent will operate to prevent the achievement of the desired result. An especially important detail is that of the angles of the tapered portions of the bore. These as shown are approximately one and one half degrees for the upper portion and nine degrees for the lower portion. Changing either of these angles as mentioned will render the device non-operative for the pur pose explained above.

In the case of either style of plug the result of an attempt to pass a wire through the plug would be to have the wire obstruct-ed by the bottom wall of the channel 19 and would o divert the end of the wire as to direct the same along the said channel and so as to avoid the lower passages 20 and 20.

lVhile our invention is shown as applied to a bottle, it is understood that the same is appliable to other structures, and whether made of glass or porcelain such as demijohns and decanters, and kindred devices.

The device as described is also applicable for bottles having considerable difierences in dimensions, by making proportional changes in the dimensions of the different parts.

While the features of the taper of the plug and the side wall are important in securing the plug in position in the neck, it is understood that in some cases some adhesive substance or cement may be used to cooperate in so holding the same in osition.

We claim as our invention A non-refillable bottle comprising a bottle body and a neck at one end thereof, the said neck comprising an outer portion at the outer end and an inner portion intermediate the said outer portion and the said bottle body and having a bore extending through the said portions, the side walls of the part of the said bore in the said outer portion having a taper of approximately one and one half degrees, the side walls of the part of the said bore in the said inner portion having a taper of approximately nine do grees forming a valve seat, and a plug 15 position will force the cork to its seat by being fixedly positloned in the said outer the power of buoyancy.
