9 Claims. (Cl. 211-133) This invention relates to hollow collapsible display devices, and in particular it relates to a structure in which an outside wrapper member of such a device is collapsibly retained in a desired shape by 'a pair of interlocking shaper members which may be assembled and inserted within the wrapper member as a unit.

Paperboard display devices are most desirably constructed in such a Way that their component parts may be shipped flat, and may be quickly assembled wherever they are to be used. Hollow display devices have been particularly diflicult to construct in this manner, and the present invention provides a very simple structure which is adaptable to upright drum-type displays, whether they be circular, polygonal or irregular in shape. It is also applicable to flllStO-COIllCfll displays.

In the construction here described a transverse shaper member has a substantial part of its periphery of the proper shape to abut against the inner face of the outside wrapper member so as to retain the wrapper member in the desired shape at a particular transverse plane, and a longitudinal shaper member interlocks with the transverse member and has at least three edges which extend longitudinally of the wrapper member and abut against its inner surface. The longitudinal shaper member isformed from a single rectangular piece of corrugated board, and is longitudinally scored to provide the desired number of edges to abut against the Wrapper member. Each face of the longitudinal shaper member is transversely slotted to receive a portion of the transverse shaper'memher, and said members may be assembled and inserted in the wrapper member as a unit.

Since displays of this type are often used as containers for small merchandise in store displays, a filler piece .preferably overlies the top of the longitudinal shaper member, and has its entire periphery in contact with the outer wrapper member. The filler piece also assists in retaining the Wrapper member in the desired shape but is not essential for this purpose. 7 i

The invention is illustrated in the accompanying drawings as applied to a circular cylindrical type of display and as applied to a square upright display.

Fig. 1 is a central vertical sectional view of a cylindrical display device made in accordance with the invention, the section being taken as indicated along the line 1-1 of Fig. 2; Fig. 2 is a horizontal sectional view taken as indicated along the line '22 of Fig. l, with a part of the longitudinal shaper member broken away; Fig. 3 is a plan view of a filler piece; Fig. 4 is a plan view of a transverse shaper member; Fig. 5 is a side elevation of the transverse shaper member of Fig. 4 viewed as from 55 of Fig. 4; Fig. 6 is a fragmentary sectional view taken as indicated along the line 66 of Fig. 1; Fig. 7 is a central vertical sectional view of a display device which is square in horizontal cross section, the section being as indicated along the line 7-7 of Fig. 8; Fig. 8 is a horizontal sectional view taken as indicated along the line 8-8 of Fig. 7; Fig. 9 is a plan view of a filler piece for 2 the device of Fig. 7; Fig. 10 is aplan view of a transverse shaper member for the device of Fig. 7; Fig. 11 is a side elevation of the transverse shaper member of Fig. 9; and Fig. 12 is a fragmentary sectional view taken as indicated along the linen-12 of Fig. 7.

Referring to the drawings in greater detail and referring particularly to the cylindrical form of the device shown in Figs. 1 to 6, inclusive, a wrapper member 11 is formed from a suitable flexible sheet material, and in the case of the cylindrical device here shown, consists of a single rectangular sheet of material which has its opposite longitudinal edges secured in overlapping relationship by means of fasteners 12. As illustrated in the drawings, the outside wrapper member :11 preferably is formed of a display material which has crease scores formed alternately in its two faces, so that it is readily rolled to the desired shape; although plain stock may be used. Conveniently the fasteners 12 may be brass paper fasteners so that the wrappermember may have an advertising message on each face, and may be assembled with either face out. With its opposite longitudinal end portions secured together as illustrated the wrapper member forms a continuous Wall; and in the particular type of display device illustrated the wall forms a right circular cylinder.

Within the wall are shaper means indicated generally at 13, which consists of a transverse shaper member 14 and a longitudinal shaper member 15 which are interlocked. As best seen in Fig. 4 the transverse shaper member has three portions the edges of which form segments '16, 17 and 18 of a circle having a radius equal to that of the interior of the wall formed by the wrapper member 11. The segments 16 are separated by notches :19, 2t) and 21, and at the centers of the notches are projecting wedge-

shaped protuberances

22, 23 and 24, respectively.

The longitudinal shaper member 15 is formed from a single rectangular piece of corrugated board which is provided with

longitudinal score lines

25 and 26 which are equidistant from its

longitudinal edges

27 and 28 so that it may be folded on the score lines 25 and '25 to enclose an equilateral triangle which has apexes at the

score lines

25 and 26 and a third apex 29 where the lon- .gitudinal' edges of the shaper member 15 meet. its three faces 39, 31. and 32 are provided, respectively, with

slots

33, 34 and 35 which extend transversely of the faces adjacent their lower ends. The slots are soproportioned that the edge 27 of the longitudinal shaper member may be positioned adjacent the apex of the central protuberance 22 in the notch 19 on the transverse shaper member, and the face 30 of the longitudinal shaper member may be engaged with the transverse shaper member so that the arcuate segment 16 extends through the slot 33 and the score line 25 is positioned at the apex of the pro.- tuberance 23. The face 31 may then be hinged on the score line 25 so as to be brought into engagement with the next arcuate segment 17, and the. score line 26 lies at the apex of the second protuberance 24. The face 32 is then hinged on the score line 26 and engaged with the third arcuate segment 18 so that its free edge 28 is adjacent the edge 27, forming the third apex 29 of the triangular area enclosed by the longitudinal shaper member. The

slots

33,, 34 and 35 are narrow enough that they frictionally engage the

arcuate segments

16, 17 and 18 so that the two shaper member 14v and 15 may be assembled and moved about as a unit.

When the display device is in its collapsed condition the two shaper members maybe assembled as previously described and may then be inserted into the space enclosed by the wrapper member 11 so as to hold said wrapper member in its desired assembled position. If

a at the

apexes

25, 26 and 29 of the triangle are 60 and the angles at the apexes of the wedge-shaped protuberances 22, 23'and 24 are also 60". In order to permit the

shaper members

14 and 15 to be assembled as described, the distance from the edge of any face of the member 15 to the opposite end of the slot in that face is greater than the distance from the apex of a protuberance to the nearest point on the adjacent notch. p

The constructional principle described with respect to the form of the device shown in Figs. 1 to is also present in the form shown in Figs. 7 to 12, in which a wrapper memberlllhas its longitudinal edge portions secured together by fastening members 112 and is scored at 113, 114, 115 and 116 so that it encloses a square area and has

side walls

117, 118, 119 and 120. In this case the wrapper member 111 is preferably formed from fiat, unfluted stock.

Atransverse shaper member 121 is square so that it has

edges

122, 123, 124' and 125 each of which is interrupted by a central notch, said notches being numbered 126, 127, 128 and 129, respectively, and there being central wedge-

shaped protuberances

130, 131, 132 and 133 in said respective central notches. The portions of the shaper member 121 between the notches

form corner projections

143, 149, 150 and 151. In this shaper member 121 instead of the angle at the apexof each protuberance being 60 as in the transverse shaper member for the cylindrical device the angle is 90.

A longitudinal shaper member, indicated generally at 134, has

score lines

135, 136 and 137 whichare spaced at equal distances from its

longitudinal edges

138 and 139, defining identical

rectangular faces

140, 141, 142 and 143. Said faces 140 to 143, inclusive, are slotted, respectively, at 144,145, 146 and '147 so that each face may be engaged with one of the corner projections of the transverse shaper member. The assembly of the two shaper members is the'same as in the cylindrical form shown in Figs. 1 to 5, with the two members being engaged as seen in Fig. 7 so that one of the central wedgeshaped protuberances of the transverse shaper member extends into each corner of the longitudinal shaper member 134; and the longitudinal edges of the longitudinal shaper member formed by the

score lines

135, 136 and 137 and by the longitudinal edges 138and 1390f said shaper member abut against the median lines of the four faces of the wrapper member 111. Each of the corner projections of the shaper member 121 extends into a corner of the wrapper member 111.

The two

shaper members

121 and 134 may be'assembled and inserted as a unit within the wrapper member 111, and a square filler. piece 152 may be rested on top of the longitudinal shaper member, said filler piecepreferably having finger openings 153 as shown.

It is plain from the foregoing description that the same principle may be. applied readily to any displaydevice ing four notches, and the longitudinal shaper member might be so constructed as to enclose a rectangle. In either of the above cases the portion'of the transverse shaper member which extends through the slots in the longitudinal shaper member is in peripheral contact with the inner surface of the wrapper member and the apexes of the longitudinal shaper member abut against the wrapper member.

'A similar. structural principle may be applied, with" minor variations to irregularly shaped display devices, or to irusto-conicaldevices. v k I The foregoing detailed description'is. given for clearness of understanding and no unnecessary limitation should be understood therefrom as variations Will'be apparent to those skilled in the art.
