Abstract: The purpose of the invention is to provide a very safe opener cap that can easily open a film serving as a section to be opened without scattering the contents. A can body (10) and a screw cap (20) are screwed together, and the screw cap (20) and an opener (30) are ratcheted together so as to rotate as a unit in the direction of the screw cap (20) tightening. Blade angles of an annular blade (34) are configured so that the blade angle in the direction of the screw cap (20) loosing is gentler than the blade angle in the direction of tightening.

Abstract: A support-equipped extracting bag for a drink, for example coffee, comprises an extracting bag member 2 containing therein a drink material to be extracted and having a front face section 2a and back face section 2b each comprising a filtering sheet; and a support member 3 attached to the bag member and covering an upper half portion of the bag member, to hygienically keep a top end of the bag member to be opened during storage and to enable the bag member to be stably and safely held in a cup, wherein the upper middle portion of the support member and the upper portion of the bag member can be opened by removing the upper middle portion of the support member and the upper portion of the bag member along cut lines 8 and 9 or vacant area 10 or 11 and a row of perforations 13 formed through the support and bag members, and by bending the right and left side upper portions of the support member inward along folds or dotted cuts 14 and 15 formed in the right and left side upper portions of the support member.
