Abstract

A multi-layer container having an outer container shell, an inner container shell mounted within the outer container shell, and a transparent intermediate bonding layer filled up the space defined between the outer container shell and the inner container shell and peripheral through holes on the inner container shell and a bottom through hole and peripheral through holes on the outer container shell, the outer container shell and the inner container shell showing a contrast in color.

Claims

1. A multi-layer container, comprising:

a cup-like outer container shell, being provided with a plurality of first peripheral through holes and a bottom through hole;

a cup-like inner container shell, being disposed inside the outer container shell, and being provided with a plurality of second peripheral through holes; and

a transparent intermediate bonding layer, being sandwiched between the outer container shell and the inner container shell;

characterized in that the second through holes are smaller than the first through holes and align with the first through holes respectively, and an annular space is arranged between the outer container shell and the inner container shell such that the intermediate bonding layer fills up the space, the first peripheral through holes, the second peripheral through holes and the bottom hole respectively;

whereby, the outer container shell, the inner container shell and the intermediate bonding layer can fixedly engage with one another, and the heat is unable to transmit to the outer container shell quickly from the inner container shell as soon as the hot liquid is received in the inner container shell.
