DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a package comprising a container which contains a liquid and a substance enclosed in an openable capsule or the like, which substance is intended to be mixed with the liquid.
The invention has a plurality of different applications but in as much as it has been conceived in connection with certain works with the design of a package which, in professional connections, permits a rapid and efficient preparation of a hot beverage, particularly coffee or tea, of a higher and more even quality than previously, and to an acceptable total cost, the invention will be disclosed hereinafter initially with reference in particular to preparation of coffee or tea on board aircraft and vehicles by mixing hot water and coffee or tea-powder, respectively, of instant type.
A package of the type as defined in the outset for a beverage comprising a liquid, preferably water, and a flavourant or nutrient additive, and intended to be heated prior to being served is previously known. This known package is characterized in that the flavourant or nutrient additive is enclosed in a known manner in an openable, watertight capsule or the like which is sealed by means of a temperature dependent substance which is active at temperatures up to a value immediately below the temperature to which the container contents are intended to be heated prior to being served, and in that the capsule is manufactured as a one piece unit from a shape-durable material and comprises parts which are mutually connected along a hinge means, and in that the capsule includes means that strive to separate the two pats, which are mutually joined in a watertight fashion by means of a respective sealing surface between which the temperature-dependent sealing substance is disposed. In the patent it has been noted that it is preferred that the capsule contains a resilient means which is intended to facilitate opening of the capsule, and further it is noted as preferred that the capsule material has a density greater than 1. Beyond that the capsule is complicated and expensive in manufacture, it is intended to flow freely in the liquid. This means that the capsule may open itself upwardly, so that an essential proportion of the substance never comes to be mixed with the liquid.
As compared to prior art technique, where a beverage is intended to be prepared by dipping a small container, that houses a concentrated food-stuff product, into liquid which is then heated up to 60.degree.-100.degree. C., at which temperature an opening into the container may be formed, e.g. in that a portion of the container wall melts, a package as defined in the outset offers inter alias the very essential advantage that the liquid and the said substance may in advance be adapted in such a manner that the combination should be the best possible from a taste point of view. Further, with the same object in view, the temperature at which the substance is made available to the liquid may be adapted to the liquid and the substance.
The prior art package as disclosed in the outset has, in a plurality of tests, been found to meet the intended demands comparatively well, viz. to permit a fast and efficient preparation of a hot beverage of a higher and more even quality than before, and to an acceptable total cost.
However, it has been found possible to achieve further improvements, both with respect to a simplified and less expensive production and with respect to a reliable function in practise.
Accordingly, the object of the present invention has been to provide a package which is reliable and which comparatively easily may be adapted to existing production techniques.
Thus, the present invention relates to a package of the kind as defined in the introductory portion of claim 1 below. The package is characterized essentially by that which is defined in the characterizing clause of the said claim.
The invention is disclosed in more details below with reference had to the accompanying drawings .
FIG. 1 is a side view, partly in section, of a first embodiment of a p
