  • the present invention relates to a kitchen utensil, such as a coffee-maker or a pan, with reversible thermochromatic decorations.
  • a kitchen utensil such as a coffee-maker or a pan
  • a lid having reversible thermo-sensitive decorations, that is, decorations reversibly sensitive to temperature .
  • thermo-sensitive decoration is located on the bottom of the container, covered by the food itself. This implies a distortion of the colour taken by the decoration based on the temperature, depending on the type of food that covers the decoration, or the complete impossibility of observing the decoration, hidden by the food.
  • the object of the present invention is to make the view of the thermo-sensitive decoration especially easy to the user.
  • FIG. 1 shows a perspective view of a first kitchen utensil, that is, a coffee-maker, provided with a lid according to an embodiment of the present invention, in a cold configuration;
  • FIG. 1 shows the kitchen utensil of figure 1 in a hot configuration
  • - figure 3 shows a perspective view of a further kitchen utensil, that is, a pan, provided with a lid according to an embodiment of the present invention, in a cold configuration
  • FIG. 4 shows the cooking pan of figure 3 in a hot configuration
  • reference numeral 1 globally denotes a coffee-maker for making coffee.
  • Coffee-maker 1 comprises a reservoir 2 suitable for containing the preparation liquid, generally water, and suitable for being heated by a heat source, like a gas stove, an electrical resistance plate, a pyroceram plate or an induction plate. [0018].
  • Reservoir 2 comprises a substantially flat bottom, intended for being placed in contact with the heat source, and a side wall 4 that extends from the bottom and delimiting, at the end opposite the bottom, an insertion opening.
  • Coffee-maker 1 further comprises a filter suitable for being inserted in the insertion opening of the reservoir and suitable for containing powder coffee.
  • coffee-maker 1 comprises a container 6 suitable for being connected to reservoir 2 so as to surmount it, for example screwing thereto.
  • Container 6 comprises an annular reservoir wall 8 which extends between a bottom portion 8a, intended for the connection to reservoir 2, and an upper edge 8b which delimits an access opening to the inside space of the container.
  • container 6 internally comprises a pipe which protrudes from the bottom of the container, provided with a through inside duct, suitable for placing the reservoir in fluid communication with the container.
  • the pipe extends from the container in a rectilinear manner, for example in central position relative to the inside space of the container, preferably up to the height of the upper edge 8b of the container itself.
  • coffee-maker 1 comprises a lid 10 suitable for being superimposed to the container for covering the inside space, generally leaving only one opening 12 free for pouring the coffee and letting the hot coffee steam out.
  • the lid exhibits a peripheral annular edge 14 intended for coupling with shape coupling to the upper edge 8b of the container.
  • the coffee-maker comprises a knob 16, arranged for example centrally to lid 10 and connected therewith for opening and/or closing it.
  • lid 10 is hinged to container 6; for example, the peripheral edge 14 of lid 10 is hinged to the upper edge 8b of container 6.
  • Lid 10 of coffee-maker 1 further comprises a first decorative pattern 20, having its own aesthetic appearance.
  • the aesthetic appearance of the decorative pattern 20 is imparted by a shape, that is, the set of lines that define the representation, and/or by a chromatic appearance, that is, by the colour or by the colours that such representation highlights.
  • the aesthetic appearance of the first decorative pattern 20 is variable according to the temperature effective on such decorative pattern. [0032]. In other words, as the effective temperature perceived by the decorative pattern 20 varies, the aesthetic appearance thereof varies, changing the shape of the decorative pattern and/or the colour thereof. [0033].
  • said decorative pattern 20 is obtained by a reversible thermo-sensitive coat, suitable for changing its colour based on the temperature effective thereon.
  • lid 10 extends on the outside surface thereof, that is, on the surface that remains visible once the cover has been placed on the container .
  • lid 10 comprises an underlying decorative pattern 22, at least partly obtained below the first decorative pattern 20.
  • the underlying decorative pattern 22 is at least partly covered by the first decorative pattern 20.
  • the first decorative pattern 20 is obtained by a reversible thermo-sensitive coat suitable for becoming transparent when affected by a temperature higher than a threshold temperature.
  • the first decorative pattern 20 is obtained by a reversible thermo-sensitive coat suitable for becoming transparent when affected by a temperature higher than a threshold temperature.
  • said first decorative pattern 20 is opaque, so as to hide the underlying decorative pattern 22 to the eyes of a user.
  • thermo-sensitive coats exhibit a threshold temperature, in jargon often called colour change temperature, variable between 50 0 C and 80 0 C, preferably between 60 0 C and 70 0 C, even more preferably of about 65 0 C.
  • the first decorative pattern comprises the representation of a lobed annular decoration that surrounds the point of connection of the knob to the lid, black coloured.
  • the underlying decorative pattern 22 on the other hand comprises the representation of a lobed annular decoration, red coloured, of such dimensions as to be covered by the first decorative pattern.
  • the first decorative pattern 20 is opaque and only the black decoration is visible (figure 1) .
  • the first decorative pattern 20 is transparent, and so the underling decorative pattern 22, that is the red decoration, is visible.
  • thermo-sensitive coating is called "reversible" .
  • the lid comprises a protective coat layer, placed in contact with the outside environment.
  • the protective coat layer covers the first decorative pattern 20 and the underlying decorative pattern 22.
  • thermo-sensitive decoration located on the coffee-maker lid is especially sensitive to temperature variations, and in particular easily detects the dispensing of coffee and hot steam from the pipe inside the container, whose liquid outlet openings are close to the inside surface of the lid.
  • the outside surface of the lid is covered with a base coat layer, located below the underlying decorative pattern.
  • the kitchen utensil is a pan 100 and lid 110 is suitable for being associated to container 106 of the pan (figures 3 and 4) .
  • Lid 110 of pan 100 comprises a first decorative pattern 120 and an underlying decorative pattern 122.
  • the lid according to the present invention is provided with a reversible thermo-sensitive decoration clearly visible to the user when the utensil is being used and in particular when the lid is arranged on the container.
  • the first decorative pattern 20, 120 comprises a plurality of spaced bands, each band made with a different coat, so that such bands become transparent at different values of the threshold temperature. In this way, it is possible to have an indication also of a plurality of effective temperatures reached.
  • the first decorative pattern 20, 120 comprises a plurality of layers having different colours and different threshold temperature, so as to become transparent at different values of the temperature reached.
  • the underlying decorative pattern 22, 122 comprises a plurality of layers having different colours. [0052]. In a variation of embodiment, the underlying decorative pattern 22, 122 consists of the same base coating layer, for example made in red colour, covered by the first decorative pattern, consisting in a coat layer that fully covers the base coat layer.
  • the underlying decorative pattern consists of the same outside surface as the lid, for example having the usual colour of aluminium, of steel or of a further material used, covered by the first decorative pattern 20, 120, consisting in a coat layer that covers a portion of the outside surface of the lid.
  • the first decorative pattern 20, 120, below the threshold temperature exhibits identical colour as the underlying decorative pattern 22, 122, that is of the base coating, so above the threshold temperature, the underlying decorative pattern differing from the first decorative layer in the shape only, appears.
  • the lid according to the present invention allows observing a variation of the temperature while cooking or making coffee. [0056].
  • the stove flame may be adjusted so as to be too weak. While cooking or making coffee, the temperature could drop and good cooking or making a good coffee would be impaired by the fact of having been carried out at too low a temperature.
  • the lid according to the present invention the user can detect from the appearance of the decorative pattern, that the temperature is too low and can remedy, for example by increasing the flame.
  • the lid according to the present invention allows detecting whether there is an abnormal operation of the heat source, for example if the gas has switched off, since such anomaly causes a decrease of the temperature, detectable also by the appearance of the decorative pattern .
  • the decorative pattern is located on the outside surface of the container (figure 5) or on the outside surface of the side surface of the reservoir (figure 6) .
