Claim 3

A feeding bottle as defined in claim 1 further comprising: the slot being formed to define a projection at one or more locations for snap-fit cooperation engagement with an indentation in the sheath.

Claim 4

A feeding bottle as defined in claim 1 further comprising: the slot being formed to define an indentation at one or more locations for snap-fit cooperation with a projection formed on the sheath.

Claim 5

In an infants' feeding bottle having a bottom wall, an outside wall and a neck portion which tapers upwardly from the upper end of the outside wall, the bottle having a longitudinal slot formed along its outside wall, the slot having its maximum cross-sectional width at a location inwardly of the longitudinal opening of the slot, the improvement comprising, in combination: the lower end of the slot terminating above the level of the bottom wall, the upper end of the slot extending above the level of the juncture of the outside wall and the tapered neck portion and merging into the tapered neck portion; an indicator device dimensioned to be removably received only through the open, upper end of the slot; and a cap engaged with the neck portion of the bottle to cover the upper end of the bottle, the cap being constructed to obstruct the upper end of the slot to preclude removal of the indicating device at least when the cap is attached.

Claim 6

In an infants' feeding bottle having a bottom wall, an outside wall and a neck portion which tapers upwardly from the upper end of the outside wall, the bottle having a longitudinal slot formed along its outside wall, the slot having its maximum cross-sectional width at a location inwardly of the longitudinal opening of the slot, the improvement comprising, in combination: the lower end of the slot terminating above the level of the bottom wall, the upper end of the slot extending above the level of the juncture of the outside wall and the tapered neck portion and merging into the tapered neck portion; an indicator device dimensioned to be removably received only through the open, upper end of the slot; and a cap engaged with the neck portion of the bottle to cover the upper end of the bottle, the cap being constructed to obstruct the upper end of the slot to preclude removal of the indicating device at least when the cap is attached.

Claim 7

A feeding bottle as defined in claim 4 further comprising: the indicating device including a transparent sheath receivable in the slot, the sheath being frictionally engageable with the slot.

Claim 8

An infants' feeding bottle as defined in claim 4 further comprising: the upper end of the neck portion being externally threaded to receive a threaded cap thereon; elongate transparent sheath dimensioned to be removably received only through the open, upper end of the slot; said indicating device being enclosed within the sheath; and the slot being disposed with respect to the threaded neck portion so as to obstruct removal of the sheath when the cap is attached.

Claim 9

A feeding bottle as defined in claim 6 further comprising: the sheath being frictionally engageable with the slot.

Claim 10

An infants' feeding bottle comprising: a bottom wall and a sidewall extending upwardly from the bottom wall, the sidewall being formed to define an elongate guideway extending longitudinally of the bottle, said guideway being open at one end, said guideway being of predetermined cross-sectional configuration; an elongate sheath received in the guideway, said sheath having a transparent portion, the elongate sheath being of cross-sectional configuration to enable it to be inserted into the guideway through the open end thereof, the cross-sectional configuration of the sheath and guideway being such as to cause the sheath and guideway to engage in a snug, frictional fit, said sheath containing an indicating device therein which is observable through the transparent portion of the sheath; and at least one of the sheath or guideway portion of the bottle sidewall being of resilient, deformable construction to facilitate said frictional engagement therebetween.

Claim 11

An infants' feeding bottle comprising: a bottom wall and a sidewall extending upwardly from the bottom wall, the sidewall being formed to define an elongate guideway extending longitudinally of the bottle, said guideway being open at one end, said guideway being of predetermined cross-sectional configuration; an elongate sheath received in the guideway, said sheath having a transparent portion, the elongate sheath being of cross-sectional configuration to enable it to be inserted into the guideway through the open end thereof, the cross-sectional configuration of the sheath and guideway being such as to cause the sheath and guideway to engage in a snug, frictional fit, said sheath containing an indicating device therein which is observable through the transparent portion of the sheath; and at least one of the sheath or guideway portion of the bottle sidewall being of resilient, deformable construction to facilitate said frictional engagement therebetween.

Claim 12

An infants' feeding bottle as defined in claim 8 further comprising: the bottle sidewall further being formed to define a depression in communication with the opposite end of the guideway to expose an end of the sheath and enable it to be pushed out of the guideway from said exposed end.

Claim 13

An infants' feeding bottle as defined in claim 8 further comprising: said bottle being molded from a resilient, flexible material and said sheath being formed from a more rigid, relatively inflexible material; and a thermometer contained within the indicating device.

Claim 14

In an infants' feeding bottle formed from a resilient, flexible material and having an elongate guideway formed along the sidewall of the bottle to receive an elongate indicating device, an improved indicating device comprising: a sheath having a base portion and a cover portion, the base portion having an elongate slot formed therein to receive a thermometer; a thermometer in the slot; at least said base portion being formed from a relatively rigid material and being dimensioned to be received in the guideway in a snug, frictional fit; the cover being transparent to enable the thermometer to be observed therethrough.

Claim 15

In an infants' feeding bottle formed from a resilient, flexible material and having an elongate guideway formed along the sidewall of the bottle to receive an elongate indicating device, an improved indicating device comprising: a sheath having a base portion and a cover portion, the base portion having an elongate slot formed therein to receive a thermometer; a thermometer in the slot; at least said base portion being formed from a relatively rigid material and being dimensioned to be received in the guideway in a snug, frictional fit; the cover being transparent to enable the thermometer to be observed therethrough.

Claim 16

In an infants' feeding bottle as defined in claim 11, said sheath and thermometer being further characterized by: a temperature scale formed on the base portion and extending along the thermometer slot, the scale being exposed through the transparent cover; said thermometer slot being longer than the thermometer to enable the thermometer to be placed initially in the slot in proper position with respect to the scale.
