AHPULLA CONSISTING OF SEVERAL PARTS.

Application filed April 2,

This invention relates to the well known ampullae consisting of several parts se arated by easily breakablepartitions. It has i become known tomake the breakable partition curved in cap shape or in tube shape and to stricture the cap-shaped or tube-- shaped part at the lower end so that when the ampulla is struck on a surface the strictured part breaks oil, the two compartments being thus made to communicate the one with the other without the ampulla itself having been opened. Ampullae of this type are difiicult to transport as the communication between the two compartments may be produced bythe breaking of the partition owing to an accidental shock.

Accordin to the invention a slight incision is cut into the vaulted part so that the use of a strictureis not necessary. The small scratch or incision produced for instance with the aid of a file into the outer surface of the glass in the manner known from the glaziers diamond, is capable'to'weaken even a thickwalled glass part so that it can be )5 easily broken off. The advantage over a stricture consists mainly in that the scratched glass breaks off without formation of splinters. According to the invention the breaking lever of the partition extends as 9 far as possible in upward direction and is securely held with slight lay within upper strictures in the glass so t at it can be used for breaking the partition only after the upper compartment has been opened and the narrow parts, which hold the breaking lever, have been destroyed. 7

It is advantageous to entertain a pressure below the atmospheric in the compartment which contains the. drysubstance and a pressure above the atmospheric in the compartment which contains the liquid so that the li uid squirts into the dry substance, when t is partition between the compartment containing the liquid is destroyed.

An embodiment of the invention'is shown,

by way of example, in the accompanying drawing in which a Fig. 1 is an elevation of an ampulla constructed in accordance with this invention.

Fig. 2 is a detail view of. the central portion of an ampulla showing another form of partition.

\ frangible 1923. Serial No. 623,525.

f designates the partition between the two compartments of the ampulla, one compartment containing for instance a solid substance and the other compartment a liquid. The vau'ted partition f carries a breaking lever d which has an annular groove 0 made by means of a file. The upper end of the held in a narrowed breaking lever (Z is groove-like frangible part 6 of the point of the ampulla.

In order to establish the communication between the upper and lower compartments of the ampulla the point of the ampulla has to be broken off at the narrowed part 6- whereby the upper end of the breaking lever 03 becomes accessible, so-that it can be moved sdewards so that its lower end breaks ofi' at the incision c, whereupon the liquid from the upper compartment of the ampulla will flow into the lower compartment.

I claim 1. An ampulla comprising two compartments, one of the compartments containing a solvent liquidv and the other containing a substance soluble in the said li uid, and a partition separating the two compartments, the compartment containing the substance tobe dissolved having a lower pressure than that containing the solvent.

liquid, whereby when the partition is broken the solvent liquid is injected'in a jet upon the said soluble substance. I

2. An ampulla consisting of several compartments comprising a compartment filled with a ,dry substance in which a pressure below the atmospheric exists and a compartment filledwith a liquid in which a pressure above the atmospheric exists, a vaulted partition separating the two compartments, a long breaking lever upwardly extending from said partition and having an annu'ar incision. at its lower end so that when said lever is moved sidewards its lower end breaks off at said incision and the liquid from the upper compartment is injected into said lower compartment. 1

In testimony whereof I ture.
