Abstract

A roll dispensing container which is used for storing an elongated web of thermoplastic material comprising plural laminae which define a multiplicity of gas-filled bubbles.. The container is constructed in a manner that permits easy measured dispensal of the web therefrom. The roll dispensing container is easily assembled from a corrugated-board blank and when fully assembled is dimensioned so as to be capable of being shipped from place to place relatively inexpensively.

Claims5

Dependent claims

A one-piece container for dispensing an elongated web composed of plural thermoplastic laminae mutually defining a multiplicity of gas-filled bubbles, said web being coiled about an axis transverse to its length to form a central cylindrical void,

said container comprising a receptacle including:
(A) a ring of at least eight equi-dimensional retangular corrugated-board segments successively joined to one another to form a peripheral side,
(B) two equi-dimensioned polygonal corrugated-board segments,
(i) each polygonal segment having as many sides as there are rectangular segments,
(ii) each polygonal segment being plane,
(iii) the two polygonal segments being parallel to each other,
(iv) the two polygonal segments being perpendicular to the rectangular segments,
(v) each of the two polygonal segments being formed of two equal half-segments,
(vi) each polygonal half-segment being joined by an integral hinge to a different rectangular segment so as to permit the two associated half-segments of a given polygonal segment to be folded to form a single polygonal segment which lies at the edges of one set of edges of the ring of rectangular segments,
(C) some of the edges of the rectangular segments to which the polygonal half-segments are not hinged having hinged thereto six-sided segments of a shape resembling the polygonal half-segments but narrower than the same,
(i) all of the narrower six-sided segments and the polygonal half-segments of the container being in-folded to extend over the otherwise-open sides of the ring,
(D) each of the narrower six-sided segments and each of the polygonal six-sided half-segments having a free edge remote from the hinged edge thereof,
(E) means providing tabs at the centers of the free edges of the narrower six-sided segments and the polygonal half-segments,
(i) all of said tabs being hinged to their associated segments,
(ii) all of said tabs being in-folded to extend into the container and being interlocked so as to be interengaged and thereby form registered trunnions that extend from the inner faces of the parallel plane polygonal segments toward the interior of the container and into the generally cylindrical void,
(F) said trunnions rotatably supporting the coiled web in the container for rolling dispensal thereof,
(G) said container further including a slot formed in one of said rectangular segments which is dimensioned and shaped to permit the web to be pulled therethrough by a user.
