## Abstract

The invention relates to portable bag for sterilizing an object accommodated therein. The portable bag comprises a flexible body defining an internal space for accommodating the object; a plurality of ultraviolet (UV) radiation emitting means arranged at opposing internal walls of the flexible body; wherein the flexible body comprises one or more layers of fabric material, with one layer of the one or more layers forming the internal walls comprising a reflective fabric material adapted to reflect ultraviolet (UV) radiation emitted from the UV radiation emitting means and UV radiation reflected from the object. The invention further relates to a method of manufacturing said portable bag.

## Claims

### Claim 1

A portable bag for sterilizing an object accommodated therein, comprising:
a flexible body defining an internal space for accommodating the object;
