Abstract

A machine ( 1 ) for processing a liquid food substance includes: a jug ( 20 ) having a container ( 21 ) and delimiting a food for containing the liquid food substance; and a base ( 10 ) that has one or more walls ( 11 ) forming a seat ( 11 ′) for removably receiving the container ( 21 ). The base ( 10 ) and/or the container ( 21 ) has one or more thermally insulating spacers ( 11 a ) spacing the base wall(s) ( 11 ) from thermally conditioned outside container wall(s) ( 21 a ) when the container ( 21 ) is received in or on the seat ( 11 ′) so as to prevent or inhibit thermal transfer from the container ( 21 ) into the base ( 10 ) via the base wall(s) ( 11 ) from the container wall(s) ( 21 a ) adjacent the base wall(s) ( 11 ).

First claim

The invention claimed is:

1. A machine for processing a liquid food substance, the machine comprising:
a jug having a container and delimiting a food cavity for containing the liquid food substance; and
a base that has one or more walls forming a seat configured for removably receiving the container,
the container having at least one outside container wall that can be thermally conditioned by the liquid food substance in the cavity and/or by processing the liquid food substance in the cavity and that faces the one or more walls of the base when the container is in or on the seat,
the base and/or the container comprises one or more thermally insulating spacers spacing the one or more walls of the base from the at least one outside container wall when the container is received in or on the seat so as to prevent or inhibit thermal transfer from the container into the base via the one or more walls of the base from the at least one outside container wall.

2. The machine of claim 1 , wherein the container is configured to radiate heat to outside of the container or absorb heat from outside of the container predominantly via one or more preferential container walls, when the liquid food substance is processed in the container received in or on the seat, the thermally insulating spacers positioned to space the one or more preferential walls from the one or more walls of the base.

3. A machine for processing a liquid food substance, the machine comprising:
a jug having a container and delimiting a food cavity for containing the liquid food substance; and
a base that has one or more walls forming a seat configured for removably receiving the container,
the container having at least one outside container wall that can be thermally conditioned by the liquid food substance in the cavity and/or by processing the liquid food substance in the cavity and that faces the one or more walls of the base when the container is in or on the seat,
the base and/or the container comprises one or more thermally insulating spacers spacing the one or more walls of the base from the at least one outside container wall when the container is received in or on the seat to prevent or inhibit thermal transfer from the container into the base via the one or more walls of the base from the at least one outside container wall,
wherein each of the one or more thermally insulating spacers is configured to space a corresponding base wall of the one or more walls of the base from the at least one outside container wall by a distance in the range of 0.1 cm to 1 cm.

4. A machine for processing a liquid food substance, the machine comprising:
a jug having a container and delimiting a food cavity for containing the liquid food substance; and
a base that has one or more walls forming a seat configured for removably receiving the container,
the container having at least one outside container wall that can be thermally conditioned by the liquid food substance in the cavity and/or by processing the liquid food substance in the cavity and that faces the one or more walls of the base when the container is in or on the seat,
the base and/or the container comprises one or more thermally insulating spacers spacing the one or more walls of the base from the at least one outside container wall when the container is received in or on the seat to prevent or inhibit thermal transfer from the container into the base via the one or more walls of the base from the at least one outside container wall,
wherein the base and the jug comprise or delimit, respectively, an off-centred, projecting member, and a corresponding off-centred, seat for the projecting member or vice versa, the off-centred seat being configured to receive the projecting member when the container is received by the seat of the base such that the container is in place for processing the liquid food substance in the food cavity, the off-centred projecting member being configured to maintain the container off its place for processing the liquid food substance in the cavity when the projecting member is off-set, relative to the off-centred seat.

5. The machine of claim 4 , wherein, when the off-centred projecting member is received in the off-centred seat, the off-centred seat and the off-centred projecting member have at least one of:
complementary shapes so that the off-centred seat and the off-centred projecting member form together a continuous outside surface;
a configuration to prevent a rotation of the container relative to the base; and
a configuration such that a downwardly oriented edge of the container rests on an upwardly oriented edge of the base or such that the edge of the container is distant to the edge of the base by no more than 0.5 mm.

6. The machine of claim 4 , wherein, when the off-centred projecting member is off-set relative to the off-centred seat, the downwardly oriented edge of the container is spaced apart from the upwardly oriented edge of the base, by a distance that is greater than when the off-centred projecting member is received in the off-centred seat.

7. The machine of claim 4 , which comprises a processing device and a control system that is configured to control the processing device, for processing the liquid food substance, the control system being configured to detect when the container is off its processing place, by measuring a characteristic of the processing device and comparing the measured characteristic to an expected value thereof when the container is in its processing place or off its processing place.

8. A machine for processing a liquid food substance, the machine comprising:
a jug having a container and delimiting a food cavity for containing the liquid food substance; and
a base that has one or more walls forming a seat configured for removably receiving the container,
the container having at least one outside container wall that can be thermally conditioned by the liquid food substance in the cavity and/or by processing the liquid food substance in the cavity and that faces the one or more walls of the base when the container is in or on the seat,
the base and/or the container comprises one or more thermally insulating spacers spacing the one or more walls of the base from the at least one outside container wall when the container is received in or on the seat to prevent or inhibit thermal transfer from the container into the base via the one or more walls of the base from the at least one outside container wall,
wherein the jug has a handle for holding the jug by an adult human hand, the handle having a connection member projecting from the container and a substantially elongated upright gripping member that is connected to the connection member at a distance from the container, the gripping member having an upper portion that is above the connection member and a lower portion that is below the connection member, the upper portion being configured to support a thumb of the hand and delimiting with the connection member an upper seat for accommodating an index finger of the hand when the handle is held by the hand.

9. The machine of claim 8 , wherein the handle has a confinement member that extends:
substantially uprightly between the container and the lower portion of the gripping member; and
downwardly from the connection member or from close thereto,
the confinement member, the lower portion and the connection member delimiting a lower seat for accommodating a portion of a middle finger of the hand when the handle is held by the hand.

10. The machine of claim 8 , wherein the upper part of the gripping member has at least one feature selected from the group consisting of:
the upper part is spaced from the container by a distance in the ra
