DETAILED DESCRIPTION OF THE INVENTION

[0027] In the drawing figures a feeding bottle for receiving milk for small children is designated overall with reference numeral 10.

[0028] FIG. 1 illustrates the feeding bottle 10 with a water bottle 11 made from synthetic material, a milk powder depot 12 (c.f. FIG. 2) a suction nipple 13 and a cover 14. The water bottle 11 is fixed at a base element 15.

[0029] The feeding bottle 10 is shown in FIG. 2 in an exploded view. Viewed from below the base 15 made from two components 16, 17 is visible wherein the base can be screwed from below onto the water bottle 11. Thus, the water bottle 11 (c.f. FIG. 3) includes a thread 18 which corresponds to a thread 19 of the base element 15.

[0030] The water bottle 11 is provided with a lower water receiving portion 20 and an upper receiving portion 21 for a milk powder depot 12, wherein an outer thread 23 is formed at the upper receiving portion 21 at an outside of the water bottle 11, wherein the outer thread is used for attaching a suction nipple ring 37,

[0031] The milk powder depot 12 includes an outward protruding collar 25 at an upper fill in opening 24, wherein the outward protruding collar is supported on a circumferential face 26 of the upper receiving portion 21 of the water bottle 11 as shown in FIG. 3. The base of the milk powder depot 12 is closed by an openable opening device 27 (FIGS. 3, 6) which includes a base element 28 and a plunger element 29 that is provided with an actuation surface 30 which protrudes out of the milk powder depot 12 into an interior of the suction nipple 13.

[0032] While the actuation surface 30 of the plunger 29 and an annular portion of the base element 28 is formed from hard synthetic material (cf. FIG. 6) the center of the base element 28 is configured as a flexible synthetic material membrane 32, whereas the opening device 27 is overall coextruded from hard and soft synthetic material.

[0033] The flexible synthetic material membrane 32 serves the purpose of compensating pressure differences that are created when cooling the filled in water that has been heated to 100 degrees C. into the water bottle 11.

[0034] The annular portion of the base element 28 includes a circumferential interlocking groove 33 at an outside while the milk powder depot 12 forms a circumferentially protruding interlocking ring 34 at a base side. With this configuration it is possible to interlock the opening device 27 from below into the milk powder depot 12 so that a closed container for the milk powder 22 is created that can be opened anytime.

[0035] A suction nipple 13 is arranged on the circumferential collar 25 of the milk powder depot 12 wherein the suction nipple includes a suction protrusion 37 including a suction opening 36.

[0036] The suction nipple 13 is initially inserted into the suction nipple ring 37 from below. Then the suction nipple ring 37 is threaded with its inner thread onto the thread 23 at the receiving portion 21 of the water bottle 11 which also fixes the suction nipple 13 between the suction ring 37 and the collar 25 of the milk powder depot 12 is.

[0037] Last not least, a cover 38 is positionable on the suction nipple ring 37 wherein the cover 38 has a recess at a topside wherein the recess contacts and seals the suction opening 36.

[0038] It is evident from FIG. 3 that the base element 15 is threaded onto the water bottle 11 due to the cooperation of the threads 18 and 19 of the water bottle 11.

[0039] Additionally, the opening device 27 is interlocked in the milk powder depot 12 and the milk powder depot 12 is inserted into the upper receiving portion 21 of the water bottle 11 after filling water with approximately 100 degrees C. into the lower receiving portion 20. Thereafter the milk powder 22 is filled into the milk powder depot 12. After inserting the suction nipple 13 into the suction nipple ring 37 the suction nipple ring 37 is threaded into the exterior thread 23 of the upper receiving portion 21 of the water bottle 11 so that the suction nipple 13 fixed at the feeding bottle 10. Thus the feeding bottle 10 is ready for use during the night.

[0040] From the drawing figures its evident that a recessed base 40 of the water bottle 11 includes a stainless steel plate 41, wherein a plate shaped heater 42 is arranged below the base 40 using a double sided heat conducting tape.

[0041] FIG. 7 shows a block diagram B of the heater 42 of the feeding bottle 10 for receiving milk for small children. A printer circuit board P is shown that is provided with SMD components at a bottom side.

[0042] The circuit board P is provided with power through an AC/DC USB adapter 33 and a USB cable that is insertable in a magnet bushing 45.

[0043] The circuit board P furthermore includes a filter/protective switch 46. This component includes a filter configured to pass EMV tests for CE certification and protective mechanisms which do not permit an unsafe condition of the appliance, e.g. with respect to fire protection.

[0044] Additionally the circuit board P includes a double comparator circuit 47 for a two level controller and for detecting the point for initial heating (37 degrees C.) after filling.

[0045] Furthermore the circuit board P is also provided with a component with 3 LEDs 49 with different colors in addition to a temperature sensor 48 wherein the LEDs can indicate a high temperature, the nominal temperature (37 degrees C.) and a low temperature.

[0046] Last not least a power switch 50 controls a heater 51 formed from four to eight resistors.

[0047] FIGS. 4-5 show a start-up of the feeding bottle 10.

[0048] In case a small child indicates a need for feeding at night, the feeding bottle 10 that is heated to 37 degrees C. is available to the user.

[0049] After removing the magnet plug 44 (cf. FIG. 7) and removing the cover 14 a finger F presses through the suction nipple 13 onto the actuation surface 30 of the opening device 27. Thus, the base element 28 of the opening device 27 is unlocked so that the milk powder depot 12 is opened and the milk powder 22 drops into the water bottle 11 (cf. FIGS. 4-5). After some shaking the milk mixture is ready and can be fed to the small child.
