## Abstract

The invention relates to an insulated container for hot drinks or the like comprising an inner cup having a generally frusto-conical cup body and a generally frusto-conical outer shell. The cup is seated within the shell so that a contact path is disposed near the upper edge of the shell, along which contact path the outer surface of the cup body and inner surface of the shell are in contact. At least one bonding spot and/or bonding area for bonding said shell to said cup body is locally formed within said contact path.

### Claim 41 (depends on 38)

The method according to claim 38 further comprising:
positioning an annular or first member with a plurality of radially displaceable or protruding pressing elements inside the cup body; and
pressing, with the plurality of radially displaceable or protruding pressing elements, against an external or second member to press the walls of the cup body and the shell together to form the one or more bonding spots.

### Claim 42 (depends on 36)

The method according to claim 36 further comprising:
positioning an annular or first member with a plurality of radially displaceable or protruding pressing elements inside the cup body; and
pressing, with the radially displaceable or protruding pressing elements, against an external or second member to press the walls of the cup body and the shell together to form the one or more bonding spots.

### Claim 43 (depends on 36)

The method according to claim 36, wherein said bonding material is a thermo sealable plastic coating the method comprising:
applying the thermo sealable plastic coating as an annular strip on the inside of said shell and/or on the outside of the generally frustoconical cup; and
heating the annular strip completely.

### Claim 44 (depends on 36)

The method of claim 36 wherein the contact path extends about a perimeter of the cup and the shell adjacent to an upper annular shoulder of the cup.

### Claim 45 (depends on 38)

The method of claim 38 wherein the contact path extends about a perimeter of the cup and the shell adjacent to an upper annular shoulder of the cup.

### Claim 46

A method of fabricating an insulated container, the method comprising:
a) forming a generally frusto-conical cup having an annular upper shoulder;
b) forming a generally frusto-conical shell having an inward curl at a lower edge thereof;
c) providing a bonding material on an inside of the shell or on an outside the cup;
c) inserting the cup into the shell until the inside of the shell or the outside of the cup seats against the bonding material along a contact path, thereby forming a substantially uniform air gap between the cup and the shell having a predetermined spacing provided by the inward curl and the annular upper shoulder; and
d) pressing the shell and the cup together in a substantially radial direction to form a plurality of bonding spots in less than an entirety of the contact path wherein said bonding spots are separated from each other by unbonded areas along said contact path.
