Abstract

An infant nursing bottle includes a bottle body, a nipple and an affixing ring, in which the bottle body has an enlarged bottle opening and a stirring fin protruded inwardly form a surrounding wall or a bottle base thereof for enhancing the mixing between the drinkable water and milk powder by hand shaking of the infant nursing bottle in any and all directions. The infant nursing bottle further includes a mixing element mounted on the affixing ring for further enhancing the mixing effect. On the surface of the bottle body, a heat detecting figure is painted thereon which would change color at a predetermined temperature. Therefore, the heat detecting figure would change color as soon as the milk or drinkable liquid in the infant nursing bottle has exceeded the temperature that is suitable for the infant to consume, so as to give a warning signal to the parents to prevent the infant from getting burned while consuming the milk.

Claims

1. An infant nursing bottle, comprising:

a bottle body having an upper end provided with an enlarged bottle opening;

a nipple having a bottom rim;

an affixing ring comprising an upper ring body and a lower ring body integrally extended downwardly and inclindedly from said upper ring body, said upper ring body which has a diameter smaller than a diameter of said lower ring body providing a top rim shoulder to retain said bottom rim of said nipple thereunder, said lower ring body having an inner lower threaded portion to directly screw with an outer threaded portion of said upper end of said bottle body, said upper ring body further providing an upper securing means which is an upper threaded portion provided on an inner surface of said upper ring body; and

a mixing element comprising a fastening ring fittedly engaged with said securing means of said affixing ring for pressing on said bottom rim of said nipple for securing and supporting said nipple in position, wherein said fastening ring provides an outer threaded portion to screw with said upper threaded portion of said affixing ring, said mixing element further comprising a stirring body extended downwardly from said fastening ring for providing a stirring and mixing effect.

2. An infant nursing bottle, as recited in claim 1, wherein said stirring body comprises a plurality of stirring ribs extended downwardly and inwardly from said fastening ring.

3. An infant nursing bottle, as recited in claim 2, furthering comprising a stirring fin integrally and inwardly protruded from an interior surface of said bottle body.

4. An infant nursing bottle, as recited in claim 3, wherein an exterior surface of said bottle body provides a heat detecting figure printed by a heating detecting paint which changes color at a predetermined temperature.

5. An infant nursing bottle, as recited in claim 2, furthering comprising a stirring fin which comprises a protruding bar integrally protruded from a bottle base of said bottle body.

6. An infant nursing bottle, as recited in claim 5, wherein an exterior surface of said bottle body provides a heat detecting figure printed by a heating detecting paint which changes color at a predetermined temperature.

7. An infant nursing bottle, comprising:

a bottle body having an upper end provided with an enlarged bottle opening;

a nipple having a bottom rim;

an affixing ring comprising an upper ring body and a lower ring body integrally extended downwardly and inclindedly from said upper ring body, said upper ring body which has a diameter smaller than a diameter of said lower ring body providing a top rim shoulder to retain said bottom rim of said nipple thereunder, said lower ring body having an inner lower threaded portion to directly screw with an outer threaded portion of said upper end of said bottle body, said upper ring body further providing an upper securing means which is a supporting rim inwardly protruded from an inner surface of said upper ring body to define an engaging groove between said supporting rim and said top rim shoulder to receive said bottom rim of said nipple; and

a mixing element comprising a fastening ring fittedly engaged with said securing means of said affixing ring for pressing on said bottom rim of said nipple for securing and supporting said nipple in position, wherein said fastening ring provides at least a slit thereon in order to provide an elastic ability for said fastening ring, and that said engaging groove of said affixing ring has an inner diameter slightly smaller than an outer diameter of said fastening ring so as to tightly receive said fastening ring within said engaging groove for pressing said bottom rim of said nipple in order to firmly support said nipple in position, said mixing element further comprising a stirring body extended downwardly from said fastening ring for providing a stirring and mixing effect.

8. An infant nursing bottle, as recited in claim 7, wherein said stirring body comprises a plurality of stirring ribs extended downwardly and inwardly from said fastening ring.

9. An infant nursing bottle, as recited in claim 8, furthering comprising a stirring fin integrally and inwardly protruded from an interior surface of said bottle body.

10. An infant nursing bottle, as recited in claim 9, wherein an exterior surface of said bottle body provides a heat detecting figure printed by a heating detecting paint which changes color at a predetermined temperature.

11. An infant nursing bottle, as recited in claim 8, furthering comprising a stirring fin which comprises a protruding bar integrally protruded from a bottle base of said bottle body.

12. An infant nursing bottle, as recited in claim 11, wherein an exterior surface of said bottle body provides a heat detecting figure printed by a heating detecting paint which changes color at a predetermined temperature.
