FIELD: tea or coffee packets. SUBSTANCE: packet 2 has two layers of porous material hermetically interconnected over strip 3 running over periphery forming cell 4 containing agent 5 to be drawn. Besides that, sheets are hermetically interconnected at two sections 6 located inside relative to peripheral strip 3 at some distance from it. Squeezing thread 7 enters cell 4 and escapes from it; it is laid as loop around sections 6 of sheet hermetic joint. Ends of thread 7 may be provided with ears 10. In using the packet, thread is pulled in opposite directions, thus compressing the packet and forcing liquid out of it. EFFECT: simplified manufacture of packets; reduced rejects. 20 cl, 4 dwg
