Description

The present invention is in the field of administration of food by the oral route and relates more specifically to a bottle with thermometer.

To measure the temperature of a liquid given to a baby, we already had the idea of combining a bottle with a thermometer.

By Swiss patent 550 584, a bottle is known having a lateral clearance intended to receive an assembly comprising on one side a thermometer and on the opposite face of the grooves intended to cooperate with the edges of the lateral clearance, to ensure the removable fixing of the temperature measurement set.

In Swiss Patent No. 557172, a bottle is described having on its outer wall a longitudinal recess provided with flanges intended to hold a thermometer slipped in this recess at the time of use of the bottle.

The thermometers used are of the mercury or aiccol expansion type, which cannot withstand the sterilization temperatures, which implies that the devices described above relate to removable connections of temperature measurement means on a bottle.

The present invention provides a thermometer bottle which can withstand high temperatures [or sterilization of the bottle. This bottle allows you to know precisely the temperature of the liquid to be administered, which is particularly interesting for users of microwave ovens who risk burning babies' throats with too hot liquid, while the bottle has remained cold.

The bottle according to the invention is characterized in that it includes temperature measurement means at least partially incorporated in the material constituting said bottle and able to withstand sterilization.

In a preferred embodiment, the temperature measurement means are constituted by a bimetallic type thermometer.

The appended drawing represents, by way of nonlimiting examples, two embodiments of the subject of the invention.

Fig. 1 is a side view of a thermometer bottle according to the invention.

Fig. 2 is a partial cross section along H-ll in FIG. 1, shown on a larger scale.

Fig. 3 is a cross section of a baby bottle having in its lower part a bimetallic thermometer.

The bottle 10 shown in FIG. 1 consists of a bottle, made of glass or plastic, having at least one substantially flat face 11 in which is embedded a device 20 for measuring temperature. It will be noted that the latter is located closer to the base 12 of the bottle than to its neck 13, in order to be able to also measure (at the temperature of a small quantity of liquid.

As shown in fig. 2, the device 20 for measuring temperature comprises a transparent bezel 21, a movable mark 22 constituted by a needle for example, secured to a spring 23.

The needle 22 moves in front of a dial 24 carrying the temperature indications.

In a preferred embodiment, the graduations are between 0 and 50 ° G, which allows the exact temperature of a hot or cold liquid to be measured. It will be noted in FIG. 1 that the cart 24 has color ranges 25 and 26, corresponding respectively to the temperatures of 30 to 40 ° for a hot drink, and from 0 to 10 °

for a cold liquid. For clarity of the drawing, there is shown in FIG. 1 the graduations corresponding to the tens, but it goes without saying that the indications can be more precise.

In fig. 2, it will also be noted that the bottom 27 of the housing 20 is of dimension greater than the diameter of the assembly, to ensure its fixing in the material constituting the face 11. As a variant, it is possible to provide for grooves on the side wall 28 .

In the second embodiment shown in FIG. 3, there is a bottle 10 containing a liquid 30 and a temperature measuring device 40 comprising, as before, a transparent bezel 41, a movable mark 42 constituted by a needle for example, secured to a bimetallic thermometer 43 shown diagrammatically in the drawing by its cylindrical shell. The needle 42 moves in front of a dial 44 carrying the temperature indications.

The bottom 45 of the housing 40 is integral with a body 46 having on its periphery a thread 47 intended to ensure the fixing in the bottom 14 of the bottle 10. In the case where it is desired to be able to separate the measuring device 40 from the bottle 10, insert a seal between these parts and provide gripping means to facilitate assembly and disassembly.

As a variant, the thread 47 can be replaced by grooves to strengthen the connection between the device 40 for measuring temperature and the bottle 10.

Without departing from the scope of the invention, it is possible to provide a combination of the embodiments proposed above, and for example to provide the measuring device 20 with a feeler passing through the wall of the bottle to come into contact with the liquid. Such a feeler, as well as the cylindrical body 43 will be made of stainless steel.

It will also be noted that a bottle as described above will allow to know with exact tude the temperature of its container, which is particularly interesting for users of microwave ovens who risk burning the throat of babies with a liquid too hot , while the bottle has remained cold.
