Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
82 words
In a disposable cooking thermometer having an elongated hollow housing with resilient means for urging an indicator rod inwardly of the housing against a thermally plastic material, the improvement comprising said indicator rod being formed of separate upper and lower axially aligned sections with a first section fitting partially within an axial depression in the other section in a first retracted position and latching means holding said sections substantially apart against the force of said resilient means in a second extended position.
Claim 2
Dependent Claim
82 words
In a disposable cooking thermometer having an elongated hollow housing with resilient means for urging an indicator rod inwardly of the housing against a thermally plastic material, the improvement comprising said indicator rod being formed of separate upper and lower axially aligned sections with a first section fitting partially within an axial depression in the other section in a first retracted position and latching means holding said sections substantially apart against the force of said resilient means in a second extended position.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
82 words
In a disposable cooking thermometer having an elongated hollow housing with resilient means for urging an indicator rod inwardly of the housing against a thermally plastic material, the improvement comprising said indicator rod being formed of separate upper and lower axially aligned sections with a first section fitting partially within an axial depression in the other section in a first retracted position and latching means holding said sections substantially apart against the force of said resilient means in a second extended position.
Claim 5
Dependent Claim
95 words
The thermometer of claim 1 further defined by the first section of said indicator rod having an outer end thereof extending from said housing, said resilient means comprising a compression spring about the first section of said indicator rod, and said latch comprising a plate pivotally connected to an inner end of the first section of said indicator rod for insertion in the depression in the second section of said indicator rod and having a sufficient length to bridge said depression under the urging of said spring in said extended position of the indicating rod.
Claim 6
Dependent Claim
43 words
The thermometer of claim 2 further defined by at least the first section of said indicator rod being formed of limitedly flexible plastic material and said latch being integral therewith and said pivotal connection being a reduced cross section of this same material.
