Abstract
Abstract Method of installing a tip on a tube for making a probe cover comprising: axially, movably supporting the tube on an axially movable support pin with the pin extending beyond the end of the tube; placing a tip on the end of the pin that extends beyond the tube; applying a force to the tip to engage the tip with the end of the tube; applying a force to the end of the tube engaged with the tip to curl that end of the tube inwardly about the tip; and applying heat to the tip to soften that end of the tube engaged with the tip and cause it to reform about the tip in the inwardly curled form induced by the force applied to the end of the tube.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
110 words
A method for forming an electronic thermometer probe cover comprising: providing a closed, metal tip member having a radially extending flange; providing a thermoplastic tube; pressing said tip member into engagement with one end of said tube; disposing a forming die about said one end for curling the end of the tube engaged with the tip inwardly about the tip; applying heat directly to said tip to heat the tip to soften the end of the tube engaged with the tip and, to cause the tube end to be reformed about the flange in an inwardly curled manner, thereby securing said tip to said tube, and forming said probe cover.
