Shipping support for yarn tubes

Claim 2

In a container for storing and shipping tubes of yarn or the like in upstanding tiered formation, including open end tubes and a plurality of support pads, each support pad comprising: a. at least two plies of paperboard each including corrugations, forming an upper layer and a lower layer; b. a plurality of pairs of curved, winglike panels integral with and cut from said upper layer and adapted to be pushed outwardly therefrom each having width dimensions corresponding to the interior dimensions of the open ends of said tubes; and, c. a plurality of integral locking tongue members cut from said lower layer and adapted to be pushed upwardly therefrom tO spread and automatically lock in position the winglike panels of said upper layer thereby forming a plurality of upstanding tube support posts for supporting the open end tubes when the upper and lower layers of each support pad are brought into registry.

Claim 3

The container of claim 1 wherein each of said pair of winglike panels have locking slots in the free edges thereof which engage a flanged portion of one of said tongue members.

Claim 4

The container of claim 2, wherein each of said winglike panels and tongue members are joined to their respective layers along fold lines which are angularly related to the corrugations of said respective layers.

Claim 5

The container of claim 3, wherein the corrugations of said upper layer extend in a direction transverse to the corrugations of said lower layer.

Claim 6

The container of claim 4, wherein the support pad is constructed from a blank consisting of two separate layers of corrugated paperboard.

Claim 7

The container of claim 3, wherein the corrugations in both the upper and lower layers extend in the same direction.

Claim 8

The container of claim 6, wherein the support pad is constructed from a single blank of corrugated paperboard divided into two layers by a fold line.

Claim 9

In combination, a support pad blank from which a support pad for storing a plurality of open end tubes of yarn or the like is constructed, and a jig frame for assembling the support pad comprising: a. a corrugated paperboard blank for forming the support pad, said paperboard blank including an upper layer having a plurality of spaced apart, paired, winglike panels cut therein, each panel having a width dimension corresponding to the interior dimension of an open end tube, and, a lower layer having a plurality of spaced apart flanged tongue members cut therein each tongue member having a width sufficient to spread apart and lock in position a pair of winglike panels in said upper layer; and, b. a jig frame having a plurality of spaced apart jig elements affixed thereto in a pattern to correspond with the winglike panels and tongue members of the support pad layers for pushing the tongue members of said lower layer upwardly and into locked engagement with the winglike panels of said upper layer when the upper and lower layers are brought into registry on said jig frame.

Claim 10

In combination, a support pad blank from which a support pad for storing a plurality of open end tubes of yarn or the like is constructed, and a jig frame for assembling the support pad comprising: a. a corrugated paperboard blank for forming the support pad, said paperboard blank including an upper layer having a plurality of spaced apart, paired, winglike panels cut therein, each panel having a width dimension corresponding to the interior dimension of an open end tube, and, a lower layer having a plurality of spaced apart flanged tongue members cut therein each tongue member having a width sufficient to spread apart and lock in position a pair of winglike panels in said upper layer; and, b. a jig frame having a plurality of spaced apart jig elements affixed thereto in a pattern to correspond with the winglike panels and tongue members of the support pad layers for pushing the tongue members of said lower layer upwardly and into locked engagement with the winglike panels of said upper layer when the upper and lower layers are brought into registry on said jig frame.
