## Abstract

A container made of silicone resin is sufficiently compactable in a collapsed state. The container includes a tubular barrel portion, a bottom portion having a flat surface, a mouth portion having an opening, and a lid portion sealing the opening of the mouth portion, with at least the barrel portion and the bottom portion formed by molding. One end of a binder is attached to the mouth portion and can hold the rolled-up barrel portion and the bottom portion.

## Claims

### Claim 1

A silicone resin container, comprising:
a tubular barrel portion of a silicone resin having first and second ends;
a bottom portion having a flat surface at said first end and being integrally molded with said barrel portion of silicone resin, said barrel portion and said bottom portion being rollable into a rolled-up state with said bottom portion forming a roll axis;
a mouth portion having an opening at said second end of said barrel portion; and
a binder of a stretchable string-shaped body having an elongated portion and first and second attachment rings at opposite ends of said elongated portion, said first attachment ring being mounted on said mouth portion, said second attachment ring being mountable on said mouth portion in the rolled-up state with said elongated portion of said body extending around said barrel portion and said bottom portion to maintain said barrel portion and said bottom portion in the rolled-up state.

### Claim 2 (depends on 1)

A silicone resin container according to claim 1 wherein
said bottom portion comprises a groove portion.

### Claim 3 (depends on 2)

A silicone resin container according to claim 2 wherein
said groove portion comprises a rectilinear groove traversing from one edge to an opposite edge of said bottom portion, extending to a side surface of a lower portion of said barrel portion and passing through substantially a center of said bottom portion.

### Claim 4 (depends on 1)

A silicone resin container according to claim 1 wherein
said binder is formed of a stretchable silicone resin.

### Claim 5 (depends on 1)

A silicone resin container according to claim 1 wherein
said mouth portion comprises a protrusion.

### Claim 6 (depends on 1)

A silicone resin container according to claim 1 wherein
a lid portion is mounted on said mouth portion and has a gasket of silicone resin.
