Abstract
Abstract Evaporator-block container having an adjustable cross section of the outlet aperture and comprising two housing components of which the one is a retaining part suitable for holding an evaporator block, the said retaining part having at least one outlet aperture for the outlet of vapors of an active substance contained in the evaporator block, and the other is a sealing part which seals or closes in an adjustable manner, either completely or partially, the outlet aperture(s) and which is connected with the retaining part in the closed position to give a sealed but releasable closure, characterized in that there is incorporated inside the housing parts a mould having an inlet aperture facing the sealing part, which is for the pouring in of evaoporator-block material in the melted state.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
217 words
An evaporator-block container comprising two housing components of which the one is a retaining part suitable for holding an evaporator block, the said retaining part having at least one outlet aperture for the outlet of vapors of an active substance contained in the evaporator block, and the other is a sealing part which seals or closes in an adjustable manner, either completely or partially, said at least one outlet aperture and which is connected with the retaining part in the closed position to give a sealed but releasable closure; a mould positioned in said housing parts having a bottom surface, a first wall part secured on the inside of one of said housing components on or at the bottom surface, a second wall part attached to the inside of the other of said housing components and which in a sealed position engages said bottom surface to provide a sealed but releasable closure, and an inlet aperture facing said other of said housing components for receiving molten evaporator-block material; and adjusting means positioned on said housing components for sealingly engaging said components so as to completely seal off the inside of the mould from contact with the outside atmosphere and, alternately, for retaining said components in a separated position at at least one specific distance from each other.
Claim 2
Dependent Claim
217 words
An evaporator-block container comprising two housing components of which the one is a retaining part suitable for holding an evaporator block, the said retaining part having at least one outlet aperture for the outlet of vapors of an active substance contained in the evaporator block, and the other is a sealing part which seals or closes in an adjustable manner, either completely or partially, said at least one outlet aperture and which is connected with the retaining part in the closed position to give a sealed but releasable closure; a mould positioned in said housing parts having a bottom surface, a first wall part secured on the inside of one of said housing components on or at the bottom surface, a second wall part attached to the inside of the other of said housing components and which in a sealed position engages said bottom surface to provide a sealed but releasable closure, and an inlet aperture facing said other of said housing components for receiving molten evaporator-block material; and adjusting means positioned on said housing components for sealingly engaging said components so as to completely seal off the inside of the mould from contact with the outside atmosphere and, alternately, for retaining said components in a separated position at at least one specific distance from each other.
Claim 3
Dependent Claim
21 words
Evaporator-block container according to claim 1, wherein the two wall parts are designed as annular walls arranged coaxially to each other.
Claim 4
Dependent Claim
52 words
Evaporator-block container according to claim 2, wherein the wall part attached to the bottom surface is secured, as the outer annular wall of the mould, in the retaining part, and the other wall part is secured, as the inner annular wall arranged coaxially to the outer annular wall, in the sealing part.
Claim 5
Dependent Claim
32 words
Evaporator-block container according to claim 1, wherein there is mounted on the bottom surface of the mould at least one guide member, by means of which the second wall part is positioned.
Claim 6
Dependent Claim
47 words
Evaporator-block container according to claim 4, wherein the adjusting means comprises one engaging element on the guide member and a second engaging element, capable of engaging with the first element, on the second wall part of the mould, which wall part is positioned by the guide member.
Claim 7
Dependent Claim
139 words
Evaporator-block container according to claim 5, wherein the one wall part of the two forming the mould is provided on its unsecured peripheral edge with at least one releasing element, and the housing part, on the inside surface of which this wall part is located in the sealed position to give a sealed but releasable closure, is provided with at least one releasing element acting together with the first releasing element, so that by rotation of the one housing part with respect to the other, the first and the second releasing element operate together in such a way that a disengaging of the two engaging elements on the guide member and on the second wall part occurs and hence an adjustment of the two housing parts to give a distance apart from each other of (d) is rendered possible.
Claim 8
Dependent Claim
40 words
Evaporator-block container according to claim 1, wherein there is provided in the sealing part at least one aperture, through which, with closed container, block material is poured in the melted state into the inlet opening of the mould located below.
Claim 9
Dependent Claim
50 words
Evaporator-block container according to claim 7, wherein there is provided a removable seal in the form of a sheet that is impervious to vapors of the active substance contained in the block material, for the sealing of the aperture(s) of the sealing part after pouring in of the block material.
