In Sweden November 24, 1932 1 Claim. (01. 229-56) This invention refers to a system or a method of procedure and the arrangements based there- 'upon for the packing, preserving and employment of two or more substances which react in respect to each'other, so that the bringing together and the mixing of them for use must be arranged to take place at a moment of time common to them all.
The chief object of the invention is to bring about a method of procedure for the packing, preserving and employment of two or more substances, so that they are held separated when packed and preserved and easily brought together and mixed simultaneously when they are to be used.
The different substances are kept in difierent pockets, these being connected with each other in such a way or placed together in such a way that, by means of an easy manipulation, the bottoms of therpockets, or some part of their sides, can be cut away, so that the substances, preferably in powder form, will simultaneously fall down into a vessel, 2. glass or other receptacle containing water, for instance, the mixing taking place when this happens. Examples of such substances are bicarbonate of sodium and tartaric acid, from which there is thus formed a carbonated beverage, with water as the dissolvent. In this process, consequently, it is of importance that the substances are not mixed together at the wrong time, as would be the case if they were enclosed in one and the same pocket, before being brought together in the water. For the above mentioned purpose, use can be made of two or more pockets of suitable material, such as paper, the bottom parts of which have running through them threads of, for instance, linen, or steel wires or lamellas of steel or some other suitable material. The threads bring about the opening of the pockets at the intended moment by pulling down the threads by hand in such a way that they will simultaneously tear and open the pockets, whereupon the substances will fall into the mixing receptacle, a glass of water, for instance.
The method and arrangements for practising the invention can, of course, be varied according to wish. For instance, a piece of paper or the like, can be folded so as to form a kind of envelope or flattened pipe. If this envelope be folded in the middle and the free lappets or ends of the envelope be brought together and gummed together, after each receptacle thus formed in the envelope has received its own substance, then there have been formed two pockets each provided with its substance. If a thread or the like open;
be inserted into, and attached to the joint end of the thus parallelly located pockets, both of them will be torn open by means of the thread, and the substances from both pockets will run out simultaneously. If more than two such pock- 5 ets are placed side by side with each other, with a tearing off string in each pair of pockets, it will be easy to make the arrangement that two or several strings can be actuated simultaneously, so that all the pockets will be opened at the same 10 time.

Fig. 2 is a vertical sectional view of the same 15 showing the envelopes closed;

Fig. 4 is a vertical sectional view of the completed deviceshown in Fig. 3;
Fig. 5 is a perspective view of the device shown in Fig. 4;
Fig. 6 is a perspective view of am tl er form of my device showing the tops of "the-envelopes;
Fig. '7 is a vertical sectional view of the device shown in Fig. 6 complete.
In Figs. 1 and 2, I show two paper envelopes i with their adjacent sides adhering together, and having their upper ends or mouths closed by a single seal 4. Lying in the dispensing-edge 2 of each envelope is a string 3, one end of which extends outside of the envelope. These strings 3 lie parallel with each other in their respective envelopes, and their loose, exposed ends are adjacent each other so that in ripping open the lower edges of the envelopes, both strings may be gripped between the fingers of one hand and simultaneously manipulated to open the envelopes. simultaneously. This arrangement of the lower, dispensing or discharging edges of the envelopes adjacent each other and providing for the simultaneous opening of the envelopes along parallel lines is important in, that the simultaneous discharge of the two ingredients is insured.
- In the modification shown in Figs. 3, 4 and 5, the two envelopes are made integral, by properly folding a single sheet of paper, and the ripping means consists of a single string lying between the two envelopes so that upon pulling on the loose end of the string both ends of the envelope will be opened, as in Fig. 1.
In Figs. 6 and 7, I show a simple arrangement whereby three envelopes or receptacles may be 5 used. 5.
An original single package for packing and preserving two or more substances which react in respect to each other but which cannot be used in the way they are intended if kept in one common receptacle, comprising two or more receptacles adapted to enclose the different substances, the receptacles being closed and fastened together along one edge and having their discharging or dispensing edges arranged adjacent and parallel to each other, and string means for simultaneously ripping said parallel discharging edges of the envelopes or receptacles, whereby by a single ripping action the simultaneous discharge of the two or more substances in the separate envelopes may be obtained.
