Description
[0018] The appended figures represent a particular embodiment of the invention in which:
[0019] FIG. 1 shows a traditional bottle in vertical
[0020] FIG. 2 shows a traditional leaning baby bottle that delivers milk
[0021] FIG. 3 represents a bottle equipped with a level measure device according to the invention
[0022] FIG. 4 represents a basic section of the level measure according to the invention
[0023] FIG. 5 shows the complete invention with the level measure coupled with its intelligent base.
[0024] FIG. 6, 7, 8 show a variant of the invention called string garland that validates the liquid level in three different holding angles.
[0025] FIG. 1 shows a traditional bottle in vertical, with its bottle (B), the bottom of its bottle (C) its nipple screwing ring (10), its nipple (T). The nipple screw ring has a side face that matches the side wall of the bottle and an upper face that partially closes the bottle. A hole is disposed on the upper face of the screw ring to pass the nipple through which will suck the baby. FIG. 2 shows a traditional tipped bottle that delivers milk. In this figure, the liquid reaches the nipple and the baby can drink. The angle (A) that the bottle makes with the horizontal is such that the liquid reaches the nipple. For the same level of liquid, if this angle (A) decreases too much, the bottle ends up being in a position where it gives air. FIG. 3 shows a feeding bottle equipped with a level ring (31) according to the invention, which is mounted at the bottom of the bottle and which circles the bottle with a maintenance and friction or holding forces designed for this ring holds an almost fixed position on the wall of the bottle. In certain variants to ensure optimum support, the level measuring ring (31) can be supported on the cutting edges (30) of bottle which often have recesses and/or bosses that are thought by the bottle manufacturers to aesthetic and/or ergonomic reasons. FIG. 4 represents a basic section of the level ring according to the invention which has arranged on a circle facing the pairs of optical sensors. Namely, for example, photoluminescent diodes placed vis-a-vis photo resistors. By placing a series of pairs of optical detectors in a series of angles and coupling it with algorithmic processing, it becomes possible to determine the level of liquid in the bottle. The particularity of the invention is that the optical detectors are preferably placed in a plane perpendicular to that of the axis of the bottle. Preferably on a ring to fit the shape of the bottle and can more easily calculate the liquid level regardless of the angular inclination of the bottle along its main axis and also with respect to the ring. Indeed, in another form of solution, by placing the pairs of diodes vis--vis two parallel planes that frame the bottle, it then becomes necessary to couple the processing of the level measurement to that of the angle ground planes to calculate the actual level of fluid in the bottle. It is also quite obvious that the calculation of liquid level gives an efficient representation in a precision of one gram of the amount of liquid in the bottle given the average density of milk given to the baby. In all cases, the essential feature of the invention is to compare one by one the measurements from a plurality of sensors to infer by calculation a level information which can then be retranscribed by weight of liquid in the bottle and/or in risk analysis for the liquid pressure at the end of the nipple depending on the angle at which the bottle is held.
[0026] FIG. 5 shows the complete invention with the level measuring ring (31) coupled to a base (52). The base (52) includes a weight sensor that may be in some bidirectional variants in the direction of the main axis of the bottle. This sensor thus makes it possible to detect the weight of the bottle when it is vertical placed on its base, and the longitudinal head forces when the baby head the bottle and therefore applies a force on the nipple. The base also includes an inclinometer. Commonly, the inclinometer is an accelerometer that takes into account the low acceleration of the bottle when used so determines its angle with the vertical. The base also obviously includes an electronic circuit with calculation means, power supply means, transmitter and receiver means for communicating with a remote terminal. The ring is connected to the base (50) by supports (51) rigid. The challenge is that double 1that the inclinometer in the base gives an accurate measurement of the angle of the bottle 2that the weight of the bottle is well on the base of the bottle. Depending on the ergonomic choices, it may then be chosen that the level ring is held firmly against the bottle and transmits its weight on the base or in an equivalent variant, that the level ring floats around the bottle but that the bottle is well maintained by a lateral outer shell shape in very small translational fringes so that 1for well-understood reasons of level calculation accuracy, the level ring is positioned in a precise area around the bottle 2that the weight effort that applies is not truncated by the holding of the hand on the bottle that could hold the ring. The holders (51) between the level ring (31) and the base (50) are therefore sliding in the case of a ring held firmly against the bottle or firm in the case of a sliding ring around the bottle. Everything is a matter of choice of ergonomics and aesthetics and both variants are possible.
[0027] FIG. 6 shows a particular arrangement of diode and sensor which optimizes both the information taking and the cost price of the product. The solution lies in a garland (G) of diodes (61), the garland is held in a plane that contains the main axis of the bottle, from the top of the bottle just under the nipple ring and down, along the main axis bottle against the side wall, then comes to marry the bottom of the bottle. In front of the garland (G), on the bottom of the bottle, towards the corner, near the bottom of the bottle is arranged a light sensor (71). The garland emits light trains that turn on and off successively one by one the diodes of the garland. The electronic board which controls the lighting of the light trains is also connected to the light sensor (71). The light sensor detects light intensity jumps when the light train is no longer masked by the opaque liquid that is the milk in the bottle. In short, when the light emitted by the light train is masked by the milk, the light intensity received is that of the ambient light. When the light emitted by the light train is no longer masked by the milk, the light intensity received by the light sensor is that of the ambient light plus that of the emitting diode of the light train. If the diodes emit sufficient light and/or if the ambient light is sufficiently masked by a masking sock which confines the emitting diodeslight sensor couples, then the system is able to detect the liquid level and detecting the diode for which the light sensor detects a received light intensity jump. This solution, unlike that of FIG. 5, has the dual interest 1to adapt to all conditions of bottle filling, bottle full FIG. 7, almost empty bottle FIG. 8, half-full bottle FIGS. 6, and 2 By increasing the number of diodes and decreasing the number of sensors, the sensors being more expensive than the diodes, for the same number of possible measurements, the cost price is therefore reduced.
[0028] It is understood that the overcap can also be a clip, a sock and that we can name it bottle dressing.
[0029] The present invention thus relates to a milk bottle cover comprising a base which houses an electronic circuit comprising calculating means, power supply means, an inclinometer, transmitting/receiving means for communicating with a remote terminal, characterized in that it comprises a garland (G) of diodes (61) emitting light, the garland is held in a plane that contains the main axis of the bottle, from the top of the bottle just under the pacifier ring and goes down, according to the main axis of the bottle against the side wall, then comes to marry the bottom of the bottle, vis--vis the garland (G), on the bottom of the bottle, to the corner, near the bottom of the bottle is arranged a sensor light (71), the garland emits light trains which turn on and off successively one by one the diodes of the garland, the electronic card which controls the lighting of the light trains is connected ega light sensor (71), the light sensor detects light intensity jumps when the light train is no longer masked by the milk to deduce the level of milk in the bottle, the calculation means couple level information to that bottle holding angle and deduce a recommendation that is addressed to the user.
[0030] Of course, in a vertical position, in a calibration phase, the data from the inclined optical sensors can be compared to that of the weight sensor data for calibration of the entire user feedback.
[0031] The invention is also capable of determining the history of taking meals: meal time, total intake, flow during the meal.
[0032] It is thus well understood that many variants of the invention may fall within the scope of the present invention.
