Abstract
Abstract In a tool for sealing containers, such as cups, bottles, jars and the like there is provided a cooling surface applicable to a plastic cap on the cup or the like and an annular nozzle to blow hot air around the periphery of the cooling surface. This cooling surface is provided on a slide displaceable in the body of the tool for controlling the passage through the nozzle such that this nozzle is exposed when the slide is moved into the body by pressure against the cooling surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A tool for sealing a container, such as a cup, bottle, jar or the like, comprising a body; an air inlet provided by said body; an air outlet provided by said body to the outside thereof; an annular air nozzle provided on said body; means forming a passage between said air inlet on the one hand and said air outlet and said air nozzle on the other hand; heating means in said passage; a slide displaceable in the body between outer and inner positions for controlling the air outlet and the air nozzle, said air outlet and said air nozzle being closed and open, respectively, when the slide is in said inner position and open and closed, respectively, when the slide is in said outer position; a cooling surface supported by the slide; and means for circulating a coolant in contact with the cooling surface, hot air being discharged around the periphery of the cooling surface when this is applied onto a cap on a container and the slide is moved to the inner position by being pressed against the cap.
Claim 2
Dependent Claim

A tool for sealing a container, such as a cup, bottle, jar or the like, comprising a body; an air inlet provided by said body; an air outlet provided by said body to the outside thereof; an annular air nozzle provided on said body; means forming a passage between said air inlet on the one hand and said air outlet and said air nozzle on the other hand; heating means in said passage; a slide displaceable in the body between outer and inner positions for controlling the air outlet and the air nozzle, said air outlet and said air nozzle being closed and open, respectively, when the slide is in said inner position and open and closed, respectively, when the slide is in said outer position; a cooling surface supported by the slide; and means for circulating a coolant in contact with the cooling surface, hot air being discharged around the periphery of the cooling surface when this is applied onto a cap on a container and the slide is moved to the inner position by being pressed against the cap.
Claim 3
Dependent Claim
30 words
A tool as claimed in claim 1, further comprising a plunger forming part of the body, which is slidingly received in the slide, said passage being formed by said plunger.
Claim 4
Dependent Claim
61 words
A tool as claimed in claim 2, wherein said plunger provides a distribution chamber for air heated in said passage by the heating means provided therein, and said body provides an annular chamber surrounding the plunger and the slide and communicating on one hand with the distribution chamber and on the other hand with the air nozzle and the air outlet.
