Abstract
A double-layer containing apparatus includes a double-layer container including an inner shell, an outer shell, and spacers. The inner shell forms a storage space. The inner shell is made of fluorine-containing thermoplastic and has a first melting point. The spacers are disposed between the inner shell and the outer shell. Each partition includes first and second surfaces. The first surface has recesses facing the inner shell. The second surface contacts the outer shell. The apparatus further comprises a heating device including a controller, wires, and electric heating elements which are correspond to the spacers respectively. A process of manufacturing the double-layer containing apparatus is also provided.

A double-layer containing apparatus, comprising:
- a double-layer container including an inner shell, an outer shell, and spacers wherein the inner shell defines a storage space of the double-layer container, the inner shell is made of fluorine-containing thermoplastic and has a first melting point, the spacers are disposed between the inner shell and the outer shell, each of the spacers include a first surface and a second surface, the first surface has a recesses facing the inner shell, and the second surface contacts the outer shell;
- and
- a heating device including a controller, wires, and electric heating elements wherein the controller is electrically connected to the electric heating elements through the wires, and the electric heating elements are disposed adjacent to the spacers respectively and are disposed in the inner shell;
- wherein the controller activates the electric heating elements to generate heat, corresponding areas of the inner shell adjacent to the recesses are heated to a temperature greater than the first melting point and become melted and deformable into the recesses, projections are formed, and the projections fill the recesses respectively;
- and then he controller deactivates the electric heating elements to stop generating heat, and the projections are cooled and solidified so as to secure to the recesses.
A process of manufacturing a double-layer containing apparatus, comprising the steps of:
- preparing a double-layer container and a heating device wherein the double-layer container includes an inner shell, an outer shell, and spacers, the inner shell defines a storage space of the double-layer container, the inner shell is made of fluorine-containing thermoplastic and has a first melting point, the spacers are disposed between the inner shell and the outer shell, each of the spacers include a first surface and a second surface, the first surface has a recesses facing the inner shell and the second surface contacts the outer shell;
- and the heating device includes a controller, wires, and electric heating elements, the controller is electrically connected to the electric heating elements through the wires, the electric heating elements disposed adjacent to the spacers respectively and are disposed in the inner shell;
- causing the controller to activate the electric heating elements to generate heat wherein corresponding areas of the inner shell adjacent to the recesses are heated to a temperature greater than the first melting point and become melted and deformable into the recesses, projections are formed, and the projections fill the recesses respectively;
- causing the controller to deactivate the electric heating elements to stop generating heat, and the projections are cooled and solidified so as to secure to the recesses;
- and
- producing a finished double-layer containing apparatus having an internal heating mechanism.
