ATTORNEYS I usefulImprovements in Bottles, of Which UNITED STATES PATENT OFFICE.



Application filed March 14,1918. Serial No. 222,439.

To all whom it may concern:

Be it known that I, THOMAS O. L. SMITH, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented'new and the following is a specification; I

This invention relatesto a bottle.

One of the objects of the present invention is to form the neck of. a bottlein such a manner that by the use of two corks or stoppers, one in the lower and one in the upper part of the neck, the bottle will serve as a receptacle for two liquids which may be kept separately until ready for use. Another object of the invention is to provide means for positively removing the lower stopper to insure a mixing of the liquids before the upper stopper can beremoved. Further ob- I jects will hereinafter appear. The invention consists of the construction and combination of parts as hereinafter more frully described and claimed, reference being had to the accompany drawings, in which Figure 1 is a side elevationgof the bottle. Fig.2 is a central vertical-section ofthe bottle. I

Fig. 3 is a plan view of the metallic screw cap employed.

I Referring to the drawings in detail, A indicates the main body portion of a bottle and 2 the neck. Formed in the lower end of the neck is a seat 3 for the reception of a stopper 4,(preferably constructed of rubber, and forme a seat. 5 for the reception of an upper stoption of the lower stopper permits the'formation of the chamber 10 which is provided for thereception of a liquid which should not be mixed with the main contents of the bottle until it is ready forv use. This is particularly true when certain chemicals in concentrated form are employed as it has been Specification of Letters Patent.

the parts and in the upper portion of the neck is Patented Aug.13, 191

found in actual practice that mixing or di-' luting of the concentrates with other liquids and materials causes comparatively rapid deterioration of same. to maintain the concentrated material in full strength condition until it isready for use.

This is accomplished in the present instance by first filling the bottle with a liquid indicated at .11. .The lower stopper .3

supportingthe glass rod 9 is theninserted and the concentrate 12 may then bepoured in .to fill the chamber 10.- The upper stopper next passed over the upper end of the rod until it engages its seat, and, as said stopper is preferably constructed ofrubber, it can readily be seen that a seal will-be formed not only between the seat 5 and the stopper but also between 'the-rod and the stopper. Thepe'rforated screw cap is next applied and when screwed into position it passes over the upper end of the 'rod which is It is therefore ideal provided with an annular groove-14. The

the annular groove: 14 by any suitable form of tool to prevent removal of the screw cap without lifting the rod 10 and-the sto pers secured thereto. This is of considerab e importance as it might otherwise-be pomible to remove the cap and the upper stopper without mixing the concentrate 12 with the liquidll.

In the present instance it is only necessary to unscrew the, cap .8. This movement will,

. metal surrounding the rod is then forced into of course, cause the cap totravel in an upa ward direction on the threads 7 and will thus i-mpartfla vertical movement to the rod 9, The lower stopper 4 is thus lifted from its seat before the screw cap and the upper stopper are entirely removed, thuspermitting the concentrated liquid 12 to pass-by-the stopperand mix with-the liquid 11; the positive mixing operation being procured entirely by the provision of the screwcap as it is impossible to-removeth1s or the upper stopper without raising the lower stopper from its seat.

While the chamber 10 as here shown 1s formed in the neckproper, it is obvious that it might 'be-jformed in the main body tion. I'therefore do not wish to limlt myself to the specific arrangement shown and I poralso wish it understood that the materials and finish of the several parts employed may be such .as experience and judgment of the manufacturer may dictate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is: a

1. A bottle having spaced seats to provide a chamber for liquid to be kept separate from the main contents of the bottle, a stopper in each seat, means connecting the stoppers, and operating means secured to said connecting means and rendering the upper stopper inaccessible for removal until the lower stopper has been lifted from its seat.

2. A bottle having a neck with seats formed in the upper and lower ends to form an upper chamber for the reception of a liquid which should be kept separate from the main contents of the bottle until r ady for use,,a stopper for each seat, a cap inclosing the upper stopper, and means preventing removal of the cap without lifting the lower stopper from its seat;

3. A bottle having a neck with seats formed in the upper and lower ends to form an upper chamber for the reception of a liquid which should be kept separate from the main contents of the bottle until ready for use, a stopper for each seat, a cap inclosing the upper stopper, a rod secured to the lower stopper passing through the upper stopper, said rod being secured to the cap so that it, together with the, lower stopper, will be lifted in a vertical direction when the screw cap is removed.

4:. A bottle having 'a neck formed with spaced seats to provlde a chamber between the seats, a stopper for each seat, a rod'secured to the lower stopper extending through the upper stopper, a closure for the bottle emme means to fixedly connect the rod to said closure whereby to cause removal of the lower stopper from its seat before the upper stopper may be removed.

5. A bottle having a neck formed with spaced seats to provide a chamber between the seats, a stopper for each seat, a rod secured to the lower stopper extending through the upper stopper,'a cap forming a closure and covering for the upper stopper through which the rod also extends, and a connection between the cap and the rod which permits the cap to be turned and the rod and stopper carried thereby to be lifted ina vertical direction when the cap is removed.

6. A bottle having a part formed with spaced seats to provide a chamber between the seats, a stopper for each seat, a rod fixedly connected to the lower stopper and having its upper end extending through and beyond the upper stopper, said upper end of the rod being formed with an annular groove, and a cap engaged over the upper stopper and having a hole to receive said upper end of the rod, the wall forming said hole in thecap being bent to engage-in the groove of the rod so that when the cap is raised the rod will be raised therewith.

In testimony whereof l have hereunto set my hand in the presence of two subscribing witnesses.
