摘要:
A package (10) for a stack of film sheets (30) has a pouch (12) that is sealed around the stack of sheets (30) and a leader (14) that is secured to the pouch (12) and engageable with a spindle (58) in a magazine (50) so that rotation of the spindle (58) can pull the pouch from around the stack of sheets (30). The pouch (12) and leader (14) are formed of different polyolefin materials with the pouch (12) comprising a material having a low coefficient of friction to enable the pouch (12) to be easily pulled around the stack of sheets (30) while the leader (14) comprises a material having a high coefficient of friction to facilitate engagement with the spindle (58) and pulling the pouch (12) uniformly.

An easy opening envelope comprising a front panel (38) and a rear panel (20), each having an upper edge, a lower edge and opposing side edges; a sealing flap (26) connected to the upper edge (22) of the front panel (38); an adhesive strip (28) extending longitudinally across the envelope on one of the sealing flap (26) or the rear panel (20) of the envelope. A continuing line of perforations (32), (34), (36) extending across a corner of the sealing flap (30), the front panel (38) and a side fold line on the side edge (24). Whereby, once the envelope is sealed, by pulling on an edge of the corner section of the sealing flap (30) and following the continuing line of perforations (32), (34), (36) the envelope can be easily opened and the content of the envelope can be conveniently removed.

Un flan pour une enveloppe reutilisable presente un vantail principal (4) avec fenetre (18) et des rabats extremes (16) et lateraux (10, 14). Sur l'un des rabats lateraux (10) est inscrite une adresse de retour (24) sur une face du flan et un adhesif decollable (22) sur l'autre face le long du bord externe. L'autre rabat lateral (14) possede un adhesif humectable (30) le long de son bord externe (28) et de ses bords extremes (26) sur la meme face du flan que l'adresse de retour. Le flan peut etre plie pour former une enveloppe dans laquelle peuvent etre introduits des documents; elle est fermee de facon decollable, le tout de maniere automatique a la machine; elle est ensuite ouverte sans en dechirer ou en detacher une partie puis elle est pliee a l'envers et fermee pour le retour du courrier avec l'adresse de retour visible au travers de la fenetre.
摘要:
A package (10) for a stack of film sheets (30) includes a pouch (12) that encloses the stack of film sheets (30), and a leader (14) that is positioned over a face (16) of the pouch (12) and is secured to a leading edge of the pouch (12) so that the leader (14) remains over the pouch (12) until an operator pulls it away from the pouch (12) and feeds it into a spindle or the like to remove the package (10) from the stack of film sheets (30).

A carton (1) with a pour spout (56) having top, bottom, front, back, and two side portions, wherein one of the side portions has a pour spout (56) therein. The pour spout (56) has a pull tab (30) connected to an orifice cover (40) at a hinge line. The orifice cover (40) is connected to the side of the carton at a second hinge line. The orifice, located directly behind the orifice cover (40), has a through-shaped bottom. The pour spout (56) is re-closeable by inserting the pull tab (30) through the orifice, back inside the carton. A re-open notch is provided for easy re-opening of the pour spout (56).
摘要:
A device for opening a container which comprises a band (13) adhesively attached to the inside surface of the envelope (10), and a non-tearable strip (12) disposed on opposite sides of the band (13) and adhesively attached to the outside surface of the container (11), the band and the strips being disposed substantially parallel to each other, whereby when the band is freed from the container and pulled away from the container, the container can be readily opened with a straight tear line which extends along the container between the non-tearable strips.
摘要:
A process is provided for the opening of envelopes made of cellulosic paper in which there is applied to at least one envelope edge as the sole reactant with the cellulose therein a non-noxious organic acid having at least one pK value at room temperature between about 1.5 and about 5, followed by the application of heat and mild mechanical action to the envelope edge.
