End parts 34c and 34d which are not welded among end parts of the sheet-like body 34 are superposed on the flat plate 23a so as to form a pocket 33 in which a refill label 32 is to be inserted and held. A groove 35 is provided along the end parts 34c and 34d so as to smoothly mount the refill label 32 in the pocket 33.</p> |
