A packed infusible bag for an infusible substance with an inner bag, which contains the substance, made of a liquid-permeable material, a string secured to the head of the bag and a packing envelope made of a liquid- and air-impermeable material surrounding the bag on all sides, with the envelope having an edge part formed of two sealed material layers enclosuring the free end of the string. The edge part bounds a hollow space of the envelope in which the bag is received, and a tag is connected via the string with the head of the bag for handling of the bag and the tag is separable from the remainder of the envelope along a separating line which leaves the string untouched. With a hermetically sealed envelope, the separating line extends in the edge part, in part closely adjacent to the hollow space, such that between the tag and the hollow space, a narrow stay is formed which can be separated by hand transversely to the regional running direction of the separating line.

A packed infusible bag for an infusible substance such as tea, comprising an inner bag containing an infusible substance and made of a liquid-permeable material, a string secured at one end to the head of the bag, a packing envelope made of a tearable liquid and air-impermeable material surrounding
A packed infusible bag for an infusible substance such as tea, comprising an inner bag containing an infusible substance and made of a liquid-permeable material, a string secured at one end to the head of the bag, a packing envelope made of a tearable liquid and air-impermeable material surrounding the bag on all sides, said material is folded along a center line defining two strip halves having free edges, said free edges of said two strip halves forming two facing abutting inner sides, respectively, said material being layered at least on one of said two facing abutting inner sides of said free edges with a heat and/or pressure activateable material sealingly connecting said free edges of both said two strip halves which lie on one another and defining and maintaining a hermetically-sealed hollow space therein in which said bag is disposed, a portion of said sealed free edges form an envelope edge part of said envelope, said envelope edge part sealingly enclosing the other end of the string therebetween, said edge part bounding a portion of said hermetically-sealed hollow space in the envelope, a tag is connected via saiD string with the head of the bag for handling of the bag, said tag constituting an integral part of said envelope edge part and separably connected from a remainder of said envelope edge part along a separating line formed exclusively in said edge part starting from different outer edges of said envelope edge part on opposite sides of the enclosed end of said string and extending from said different edges on said opposite sides up to but space apart from said enclosed end of said string and closely adjacent to said hollow space, such that the area of said envelope edge part immediately adjacent both sides of said enclosed end of the string is sealed a portion of said separating line extending in said edge part along and closely adjacent to said hollow space defining a narrow web between said tag and said hollow space, said narrow web constituting a portion of said envelope edge part, at least a portion of said separating line and said portion of said separating line constituting a perforated tear line, said perforated tear line starting from at least adjacent one of said different outer edges and extends exclusively in said envelope edge part on one of said opposite sides of said enclosed end of said string up to an inner end point of said tear line in said envelope edge part on said one opposite side of said enclosed end of said string, said end point being spaced from said string on said one opposite side, another portion of said separating line being defined by at least one first cut starting from another of said different outer edges and formed and extending exclusively in said envelope edge part on the other of said opposite sides of said enclosed end of said string up to an inner first point of said another portion of said separating line in said envelope edge part and directed toward the sealed hollow space such that thereby the envelope can be torn through the hollow space, said inner first point being spaced from said string on said other opposite side of said enclosed end of said string, said inner first point on said other opposite side of said enclosed end of said string corresponds, at least approximately, line symmetrically relative to said string with respect to said inner end point of said tear line in said envelope edge part on said one opposite side of said enclosed end of said string, said inner end point of said tear line and said inner first point of said at least one first cut defining an imaginary straight line therebetween exclusively in said envelope edge part through said area, whereby said tear line can be torn from said one edge to said inner end point and across said narrow web to said hollow space and the torn-through envelope to release the tag so that the bag and tag can be removed from the envelope.
