Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed February 17, 1906. Serial No. 301,628.

To all whom, t may concern/s f Be it known that l, AUGUST Einen, a citizen of the United States, and a resident of the city of New York, borough of Manhattan,

in the county and State of New York, have l invented a new and improved Bottle and Bottle-Closure, of which the following is a full, clear, and exact description. I Th's invention relates to bottles and bottle-closures.

The invention is especiallynseful in connection with bottles containing chemicals. When Stoppers of cork are used for closing bottles containing chemicals, they are objcctionable,for the reason that they tend to con taininate the contents. On the other hand, rubber Stoppers are apt to be attacked by the chemicals and will deteriorate. Bottles used for containing chemicals are commonly provided with slightlyetapered ground-glass Stoppers; but these are open to objection. for the reason that they frequently become so tightly secured in position that it is impossible to remove them without breaking the stopper or the bottleeneck. Other defects with glass Stoppers are especially noticeable in acids, such as nitric acid, or volatile substances like ether, ac., which have a tendency to fume, and also where the contents of the bottle includes an elllorescent salt which tends to deposit around the stopper. This action frequently lresults in a lirn'i ce inenting of the stopper in position, with the disadvantages referred to above. Stoppers of the class referred to above-the mouths of the bottles are not properly protected against dust and atmosphericl iniluences.

The object of this invention is to provide efficient means for effecting the closure of bottles such as Idescribed which will overcome the aforesaid defects.

. The invention consists in the construction and combination ofparts to be more fully described hereinafter andpartieularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a -vertical section through the neck of abottle and illustrating a form of my invention. Fig. 2 is a view similar to Fig. 1, but illustrating a modified form. Fig. 3 is a view similarjto Figs. 1 and 2 and showing a With I third modified form. Fig. 4 is a View similar l to the foregoing figures, but representing a special forni of the invention especially i adapted for permitting the escape of fumes from the interior of the bottle, Fig. 5 is a vertical central section through the bottle i and showing a forni which the invention may l take which enables the influx or efflux of gases from the interior, and Fig. 6 is a side elevation of a stopper of special form.

Referring more particularly to the parts, 1 l represents a bottle, the body of which may be g of any suitable forni, the said bottle being provided with a neck 2, preferably having substantially the form shown. At two or more points the iinier diameter of this neck is restricted, as shown, so as to forni seats 3 and erably of glass, as illustrated, and formed below into a ball having a ground-glass belt or shoulder 7, which is ground upon the seat 3, and having thereabovc a belt or shoulder S, which is ground upon the seat 4. Between the seats 3 and 4 the bottle-neck is enlarged, preferably, so as to forni a chamber 9, and above the seat 4 the neck is enlarged again, so as to form a chamber 10, the wall whereof terminates above in a mouth 11. The Stopper 5 is formed with an upwardly-princeting stem l2, which is preferably slightly tapered, as indicated. 1n the mouth 11 there is seattightly in the mouth, as shown, the said stopper being provided with a central opening 14, through which the stem 12 passesupwardly, as indicated. When the auxiliary stopper 13 is forced into position, as shown, the stopper 5- is securely held in place, so as to make anair-tight closure for the bottle, and at the same time there is no possibility of tl 1c contents or the fumes therefrom reaching the auxiliary stopper, so as to exert a destructive action thereupon. While the ground belts 7 and 8, which come upon the seats 3 and 4, are amply sullicient to make a may be readily ,removed after removing the auxiliary stopper 13, as the area of/t'he belts is small enough to prevent any cementing action taking place between the surfaces of the glass which come together. In this connection attention is called to the fact that the belt 8 is removed a suflicient distance above the belt 7, so that even in the event of a quan- 4 for a stopper 5, the said stopper being prefed an auxiliarv stopper 13, which may be of -rubber or similar material, which seats IOO vsubstantially air-tight closure, the stopper 5 IIO tity of acid lodging at the belt 7 the chemicals would not reach the belt 8, so that no cementing effect whatever could take place at this point. The diameter of thev seat 3 is preferably smaller than the diameter of the seat 4, as shown.

yIn Fig. 2 a form of. the invention is shown in which the glass stopper is used, seating in the neck 16 ofthe same form as the neck 2, described above. The auxiliary rubber stop.-

per 13, however, is dispensed with and a glass In Fig.` 3 a modified form is shown, ini" l i which the neck 23 ofthe bottle and the stopper 24 are similar to those described above, the only difference being that the stem 25 of the stopper 24 is formed integrally with the cap 26, said cap having a depending flange 27- forming a space around the mouth of the bottle adapted to receive a seal 28, of wax or similar material. Such an arrangement as this, or an arrangement such as that described in Figs. 1 or 3, is especially desirable when bottles containing chemicals are being shipped.

Where the contents ofthe bottle are highly volatile, so that there is danger of a breaking pressure being developed within the saine, I

rovide a construction such as that shown in ig. 4, in which the bottle-neck 29 has the form described above and the stopper 30 has the same general form as the glass Stoppers described above. In this case, however, the stem 31 of the stopper is extended'above the mouth of the bottle, as indicated in Figs. 1 and 2. Upon the 'induth of the bottle a bonnet 32 is seated, the same being secured to the lip 33 of the bottle by any vsuit able means, such as an elastic band 34, arranged as shown. The bonnet 32 presents an elongated neck 35, which terminates 'above in a head or bulb 36,

'which bulb is provided with vents 37, .as

shown. Upon the upper extremity of the stem 31 a rubber tipV 38 is received. The stem 31 passes loosely through the neck 35. With closures of this form if gases should generate beneath the stopper 30 these. may operate to displace the stopper, permitting t e gas to escape upwardly into the mouth ofl the neck, whence it will pass into the neck 35 through the bulb 36,-thence through the vents 37. The bonnet 32 is not injured by' the rising of the stopper 30 in themanner described, by reason of the rubber t1 p 38, which operates as a pad to prevent the reaking of there has been an unduly large absorption of gases or fumes by the liquid. In tliis instance I prefer to use the construction shown in Fig. 5, in which 39 represents a bottle having a body of any common form, said body having an upwardly-projecting neck 40, having two seats 41 and 42 of a suitable diameter. A stopper 43 consists of a glass tube which extends down into the interior of the bottle and floats therein. The upper portion of this tube is formed into shoulders 44 and 45, which normally lie, respectively, at the seats 41 and 42. These shoulders fit nicely at these seats but it should be'understood that the closureis simplya sliding one, so

that the tube or stopper 43 may be readilyv raised or lowered. Between the shoulders 44 and 45 the stopper lias a neck 46 of reduced diameter, and a reduced neck 47 is formed below the shoulder 45. Likewise, above the shoulder 44 the diameter of the tube is reduced so as to form a tip 48. This tip extendsupwardly and passes through an opening 49Yin the dust-ca )0, which seats upon the mouth of the bott e, as shown. The dimensions and weight of the tube are such that it will normally float in thebottle in the position shown in Fig. 5.. Should undue absorption of gases or fumes occur, the atmosgeneral form shown in Figs. 1 to 4, the upper i pheric pressure above the bottle will depress the tube or stopper 43 sufIiciently to move the shoulders 44 and 45 out of engagement with their seats 41 and 42, or itwill movethe Stoppers sufficiently to enable a quantity of air to pass downwardly into the interior of the bottle. In this way equilibrium will be restablished. Y

In Fifr 6 I illustrate a stopper 51 of the extremity of the stem 52 of the stopper being rovided with a head 53, which faci itates its TGC iro

ein rotated to seat the stopper in case it shou d become stuck.

While I have described a closure presenting two seats for the stopper and a stopper having two belts corresponding to the seats, it should be understood that one belt may be used, or even three or more seats could .be

used, coperating with the corresponding,

should pass into the chamber 9, as shown in Y Y Fig. 1, this liquid will not reach the seat 4 and no danger of cementing at this point results. By reason-prof the fact, also, that the neck are removed from each ot er I am enareas of contact between the sto per'and the abled to make these areas relatively very small, so that even in the event of the ceinenting together of the glass surfaces the sto er may l be readily removed. The wirilili of these beltson the Stoppers and the seats will of course be changed to suit special 'circumstances or to suit the propertles of different chemicals to be held. S ecial at-y tention is called tothe fact, also, t at in thel form shown in'vFig. 4 the vents 37 are ar-` ranged on the under side of the bulb 36, so that while escape of the gases Vfrom the interior is ermitted the bonnet operates sub-l 'stantia ly as a dust-cap, preventing the settlement of dustin lthe mouth of the neck.

The restrictions in the bottle-necks necessary to form the seats do not tend to prevent the free flow of the liquid. On the contrary,

they seem to promote a freer flow, as they ap.-

ear to facilitate the ascent of the. air as the uid descends.

Attention is called to lthe fact that in theconstruction of the bottle-neck it is only necessary that the restrictions forming the seats for the stopper occur in the bore o the neck.4

These may be formed as shown but the same effect may be produced on a neck having a plain cylindrical outline by thickening the.

material of the neck to form annular projections or shoulders which would constitute seats.

Having thus. described my invention, I claim as new and desire to secure by Letters Patent- 1. A bottle having a neck presenting a seat of restricted diameter with a chamber below said seat, `a second seatV below sald iirst seat and a stopper presenting rigidly-connected 3. A bottle having a neck' presenting a seat below of smaller diameter than said first seat,

said neckhavinga chamber Jformed in saidlv .neck between said seats, a stopper having shoulders resting respectively on said seats and cutting off said chamber from the interior of said bottle, said stopper having a reduced body'ri idly connecting said shoulders.

4. A bottle of restricted diameter therein with a chamber below said seat, a second seat below said first seat, and a stopper having rigidly-connected shoulders resting on said seats andy cutting offVA communicationl between said chamber and the interior of saidbottle, said stopper having a rigid cap at the u per eX- tremity thereof seatlng on the mout 1 of said neck and adapted to be sealed thereto. i

In testimonywhereof I have signed my name to this specication in the presence of two subscribing witnesses.
