The present invention consists of a microwave (oven)-driven milk boiling device, useful to boil natural milk or milk-powder or to make chocolate or similar items, or even to boil water; being the boiling made under pressure and during a pre-determinate time, the jug being further useful to serve the boiled milk and the like directly to the table, having an efficient use.
The invention is a new, since there is no notice of a similar domestic or foreign jug for use in microwave oven, as conceived.
As is well-known, milk usually is brought to a boil under fire action and when reaching boiling point, the liquid comes to ebullition and grows in volume, thereby forming gaseous bubbles which rise within the container, which is then removed from the fire to prevent spillage. It is from the state of art a milk jug that uses a cone within a coverless pan-shaped container, which allows the milk to remain boiling, both in the fire and in a microwave oven.
The present invention brings milk to a boil in a filed container and places the already boiled milk in another container, within a period of two minutes, which may vary depending on the microwave oven used. The milk placed in the second container does not spill, because this container contains walls, bottom and a plastic-covered aluminum cap, proper to use in microwave and for food.
The heat is until the boiling point occurs because, under microwave action, friction of mixed liquid and solid molecules is initiated and, with the boiling, steam is formed with a sufficient force to impel the liquid from the bottom container through two sequential tubes, to fall into the upper container, ready to serve at the table and where the liquid is most re-boiled due to the aluminum protection of the upper container.
Both pure milk and chocolate can be boiled likewise, after adding powder to cold or warm milk.
Likewise, it is also possible to prepare milk with water and milk-powder, and further cappuccino or coffee with milk-powder, simply adding powder to cold or warm water and then operating the microwave oven for the same period of time as to boil natural milk.
Thus, one may obtain perfectly sterilized liquids in an adequate form for alimentation, especially for babies, when milk-powder is used and that, in order to become pure, must be prepared in sterilized water.
MATERIALS: In the making of parts to be described below, microwave oven-resistant and proper to food materials are used the internal walls of the serving container 19′ being made in aluminum and covered with plastic; in all parts, plastic (Polyeter Imida PEI) will be used since the material is unbreakable, transparent resistant to high temperatures, proper for microwaves and meets FDA standards in USA, or other standards produced in Brazil or abroad, which may have at least the same technical specifications as that.
PARTS: BOILING CONTAINER 19—(FIG. 2—Cross-section and FIG. 3—Topview): a, cylinder-shaped plastic container having—a first opening 21 in the first upper part 23 with about 9 cm diameter; at the external part near that first opening 21 it has four points in solid cubic format 1, with face with about 10,5 mm, and which will serve to fasten this part to the SERVING CONTAINER 19′ (see
SERVING CONTAINER 19′—(FIG. 4—Cross-section and FIG. 5—Topview section): an aluminum mug-shaped cylindrical container 4 entirely covered with plastic, containing a second opening 5 of about 9 cm diameter in the upper part, containing in the bottom 26 a hole 6 with approximately 1 cm diameter with plastic cylindrical walls 28 around it, which rise both from the bottom 26 to the internal part 7 for about 2 cm and, likewise, to the outside part, which serve to fasten the two liquid conducting tubes 40 and 40′ as seen in
LIQUID CONDUCTING TUBES 40 and 40′—(FIGS. 6A and 6B)—Cross-section and topview; and FIGS. 7A and 7B—Cross-section and topview): made in plastic in cylindrical format, with a size near containers 19, 19′ height and diameter of about 1 cm.
In the occasional obstruction of the first tube conducting 40, the safety valve of the BOILING CONTAINER 19 (see
PRESSURE SEALING 50—(FIG. 8—Cross-section and FIG. 9—topview section); a rectangle-shaped plastic piece, having in one of its ends and in the width part, the added format of a convex half-sphere 51, which will fit into the excavated space 52 existing in the side wall 22 near the first opening 21 of the BOILING CONTAINER 19 (see
SERVING CONTAINER CAP 20—(FIG. 10—Cross-section and FIG. 11—topview section): made in plastic and cylindrical format, it contains in its upper part a round shape gripper 15 in order to grip it, and a cylinder-shaped side wall 17 containing four L-shaped hollows 16, intended to fit into the second opening 5 of the SERVING CONTAINER 19′ (see
FILLED BOILING CONTAINER 19 (see
MILK JUG 30 operation is now described, whose procedures are mostly common in its general use.
The BOILING CONTAINER 19 is taken at normal position that is, with first opening 21 upwards, and places in it natural milk or previously mixed with filtered water or chocolate or chocolate products, or cappuccino powder, or coffee powder with milk, in the recommended measures, and mixing until dissolved, the same procedures to fill as shown in
The objective to obtaining the liquid boiled and sterilized to drink. Then, as it is seen in
As it can be seen in
A table indicating heating time in relation to the temperature reached according to type or brand of the microwave oven used, and in accordance with the amount of liquid to be boiled, should be sold with some manual for user's guidance that, thus, will then know in a short period of time, the own table for the temperature x time to be used in his/her microwave oven.
