Abstract
Abstract A method of forming a thermometer structure, such as a low cost clinical thermometer, wherein the thermometer enclosure structure is formed of plastic as by molding. The capillary element of the thermometer is molded about a taut wire and is removed from the molding cavity by being urged along the wire to an exterior position. The thusly removed element is utilized as a pressure-applying means on the wire to hold the wire taught for subsequent molding of a subsequent element in the mold cavity. The subsequent element is then utilized to remove the previous element from the end of the wire and replace it as the means for holding the wire taut for molding a second subsequent element about the wire. A scale is located on the capillary element by accurately determining the top of the liquid column at a preselected temperature and coordinating the placement of the scale on the element relative to said determined level. One end of the capillary bore is closed by a heat sealing process wherein a projecting portion of the element is deformed to seal the bore end.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
85 words
A method of forming a thermometer structure comprising the steps of: molding about a taut wire in a cavity an elongated thermoplastic capillary element; urging the molded element on the wire to a position outside the molding cavity; and maintaining a force against the molded element on the wire to transfer the force to the wire as a result of the substantial frictional engagement therebetween to maintain the wire taut during a subsequent molding of a subsequent capillary element about the wire in the cavity.
Claim 2
Independent Claim
85 words
A method of forming a thermometer structure comprising the steps of: molding about a taut wire in a cavity an elongated thermoplastic capillary element; urging the molded element on the wire to a position outside the molding cavity; and maintaining a force against the molded element on the wire to transfer the force to the wire as a result of the substantial frictional engagement therebetween to maintain the wire taut during a subsequent molding of a subsequent capillary element about the wire in the cavity.
Claim 3
Dependent Claim
28 words
The method of forming a thermometer structure of claim 1 wherein an abutment member is urged against one end of the molded capillary element to maintain said force.
Claim 4
Dependent Claim
36 words
The method of forming a thermometer structure of claim 1 wherein said first named molded capillary element is urged off one end of the wire as an incident of a movement of the wire outwardly therefrom.
Claim 5
Dependent Claim
16 words
The method of forming a thermometer structure of claim 1 wherein said wire is metal coated.
Claim 6
Dependent Claim
17 words
The method of forming a thermometer structure of claim 1 wherein said wire is coated with brass.
Claim 7
Dependent Claim
31 words
The method of forming a thermometer structure of claim 1 wherein said molded element is substantially fixedly positioned on the wire during movement thereof to said position outside the molding cavity.
Claim 8
Dependent Claim
46 words
The method of forming a thermometer structure of claim 1 wherein said molded element is retained at said position outside of the mold cavity and said wire is withdrawn through the retained molded element to be redisposed in the cavity for molding the subsequent element thereon.
Claim 9
Independent Claim
109 words
A method of forming a plurality of plastic bodies on a wire comprising the steps of: providing a plurality of separable mold elements defining in a closed position a mold cavity; disposing a wire in a molding position extending tautly through the cavity; molding an elongated plastic body about the taut wire in the cavity; separating the mold elements to expose the molded body; moving the wire and molded body thereon outwardly from between the mold elements; holding the molded body while moving the wire through the body to be redisposed in said molding position; moving the mold elements to the closed position; and repeating the above named steps.
Claim 10
Independent Claim
109 words
A method of forming a plurality of plastic bodies on a wire comprising the steps of: providing a plurality of separable mold elements defining in a closed position a mold cavity; disposing a wire in a molding position extending tautly through the cavity; molding an elongated plastic body about the taut wire in the cavity; separating the mold elements to expose the molded body; moving the wire and molded body thereon outwardly from between the mold elements; holding the molded body while moving the wire through the body to be redisposed in said molding position; moving the mold elements to the closed position; and repeating the above named steps.
Claim 11
Dependent Claim
34 words
The method of forming a plurality of plastic bodies of claim 8 wherein said wire is partially withdrawn from the molded body as an incident of said wire being redisposed in said molding position.
Claim 12
Dependent Claim
35 words
The method of forming a plurality of plastic bodies of claim 8 wherein the wire is fully withdrawn from a previously molded body as an incident of said wire being redisposed in said molding position.
Claim 13
Dependent Claim
44 words
The method of forming a plurality of plastic bodies of claim 8 wherein the wire is fully withdrawn from a first previously molded body and partially withdrawn from a second molded body as an incident of said wire being redisposed in said molding position.
Claim 14
Dependent Claim
32 words
The method of forming a plurality of plastic bodies of claim 8 wherein said molded body is fixedly retained on said wire during said movement thereof outwardly from between the mold elements.
