ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a nursing bottle, and more particularly to a thermometric nursing bottle that has a seal to prevent the liquid in the thermometric nursing bottle from leaking when attaching/detaching the thermometric device to/from the thermometric nursing bottle.
2. Description of Related Art
A conventional thermometric nursing bottle in accordance with the prior art shown in
FIG. 5
, comprises a body (
81
) having an open bottom and a connecting portion (
82
) inwardly radially extending from an inner periphery of the open bottom of the body (
81
). A base plate (
83
) is securely attached to the connecting portion (
82
) of the body (
81
). The base plate (
83
) has a threaded portion (
831
) formed on a periphery of the base plate (
83
) and an opening (
832
) centrally defined in the base plate (
83
).
A thermometric device (
9
) is mounted on the bottom of the body (
81
). The thermometric device (
9
) has a skirt (
91
) with a threaded inner periphery corresponding to the threaded section (
831
) of the base plate (
83
) such that the thermometric device (
9
) can be screwed onto the threaded section (
831
) of the base plate (
83
). The thermometric device (
9
) has a protrusion (
92
) centrally extending from the thermometric device (
9
) and corresponding to the opening (
832
) in the base plate (
83
). The thermometric device (
9
) has a thermometric sensor (
94
) electrically connected to a circuit (not shown) in the thermometric device (
9
) and extends through the protrusion (
92
). An o-ring (
93
) is mounted around the protrusion (
92
) and partially received in the protrusion (
92
). The thermometric sensor (
94
) is contained in the body (
81
) and the base plate (
83
) securely abuts the o-ring (
93
) to seal the opening (
832
) when the thermometric device (
9
) is mounted to the bottom of the body (
81
).
With reference to
FIG. 6
, the base plate (
83
) of the above nursing bottle has an opening (
832
). Consequently, the body (
81
) loses the containing function and the remnants liquid flows out of the body (
81
) through the opening (
832
) when the thermometric device (
9
) is detached from the body (
81
).
The conventional nursing bottle has two locations may cause a leak, one between the connecting portion (
82
) and the base plate (
83
), and the other between the opening (
832
) and the protrusion (
92
). However, the leak between the opening (
832
) and the protrusion (
92
) is easily solved by the o-ring (
93
). As usually, the connecting portion (
82
) and the base plate (
83
) are secured to each other by ultrasonic waves welding. The ultrasonic waves welding can provide a good strength to the structure, but cannot effectively seal the seam between the connecting portion (
82
) and the base plate (
83
). It will take a lot of manufacturing cost for a good sealing effect between the connecting portion (
82
) and the base plate (
83
) by ultrasonic waves welding. Consequently, the structure of the conventional thermometric nursing bottle needs to be advantageously altered.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional thermometric nursing bottle.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide an improved thermometric nursing bottle that has a seal to prevent the liquid in the thermometric nursing bottle from leaking when attaching/detaching the thermometric device to/from the thermometric nursing bottle.
To achieve the objective, the thermometric nursing bottle in accordance with the present invention comprises a body having a chamber defined for containing liquid. An opening is defined in the bottom of the body, and a loop is attached to the bottom of the body and having a threaded section formed on a periphery of the loop. A seal is made of resilient material and mounted within the opening and has a seam defined in the seal. The seam is closed due to an elasticity of the seal. A thermometric device has a skirt upwardly extending form the thermometric device and having a threaded inner periphery such that the thermometric device can be screwed onto the threaded section of the loop. A thermometric sensor upwardly extends from the thermometric device and extends through the seal via the seam into the chamber for sensing a temperature of the liquid in the body.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
