Claim 1
Independent Claim
438 words
A soft dispenser package of plastic film for accommodating disposable cellulose paper handkerchiefs, said package having a generally parallelepiped configuration including a front wall, a rear wall, opposed side walls and opposed end walls, at least one perforation line defined in at least one of said walls to implement the tear opening of the package, and an adhesive strip connected at its respective ends to adjacent wall portions of said package on opposite sides of said perforation line, characterized by: (a) two generally converging perforation lines (29, 30) jointly defining a boundary of a tear open flap (26) on the front wall (15) of said package, (b) a transversely directed, continuous separating cut (32) in said front wall delimiting a finger grippable end (31) of said flap, (c) opposite ends of said separating cut directly joining with converging ends of said perforation lines at an angle such that upon pulling an end of said adhesive strip upwardly to initially open the package, tearing force is directed along said perforation lines toward opposite corners (27, 28) of the front wall adjacent an end wall (19) of the package, (d) the adhesive strip (40) engaging said flap end and an immediately adjacent portion of said front wall and sealingly overlying said separating cut when said package is closed, the width of the adhesive strip corresponding to the length of the speparating cut, (e) diverging ends of the perforation lines extending outwardly to said opposite corners (27, 28) of the front wall adjacent said end wall (19) of the package, (f) connecting perforation lines (33, 34) further defining said flap in said end wall and continuing from said perforation lines at said corners, and (g) the adhesive strip having a non-adhesive grip tab (43) on its end engaging said front wall, whereby upon opening said flap exposes a full width portion of said front wall together with a full width portion of said end wall, to thereby enable the easy removal of individual handkerchiefs from the package, wherein (h) the end wall (19) is formed, in sequence, by folding in opposite first and second flaps (14) adjoining the side wall, a third flap (13) adjoining the rear wall, and a fourth trapezoidal flap (12) adjoining the front wall, (i) the connecting perforation lines in the end wall are provided in the first and second flaps and run along lateral folded edges (35) of the fourth flap, and (j) a plurality of paper handkerchiefs arranged in a stack in the package with end folds (44)thereof directed towards the opening formed by the tear flap to facilitate seizing the handkerchiefs when removing them.
