6 Claims. (Cl. 229-32) This invention relates to folding paper trays. j

More particularly, the invention is concerned with trays formed from folded paper board lengths and adapted to hold a tin can or similar object which rests partly within the tray and is partly exposed.

The general object of the invention is to provide an improved tray of the type indicated, in which danger of tearing at certain points is eliminated.

A further object is to provide a tray in which gluing and even the use of any interlocking flaps or tabs may be eliminated.

A tray embodying the invention in a preferred form will now be described with reference to the accompanying drawing, and the features forming the invention will then be pointed out in the appended claims.

In the drawing:

Fig. 1 is a at plan view of a blank for forming the tray of the invention;

Fig. 2 is a partial plan view, showing a stage in folding the blank;

Fig. 3 is a side elevation, partly in section, showing the completed tray;

Fig. 4 is a section on the line 4--4 of Fig. 3; and

Fig. 5 is a plan view of the completed tray.

The blank comprises a rectangular bottom panel having trapezoidal end panels 11 joined to it on fold lines 12, which end panels, in turn, have substantially semi-circular flaps 13 joined to them on fold lines 14. Side walls 15 are hinged to thc bottom 10 along fold lines 16 and carry end tabs 17 on diagonal fold lines 18, which fold lines join the fold lines 12 at one end and terminate in a gusset structure at their other ends. The gusset structure includes a continuation 18 of fold line 18, a generally triangular panel 19 hinged to panel 17 on fold line 20 which parallels the edge 21 of panel 17, and a second generally triangular panel 23, hinged to side wall 15 along the fold linel 24.

In setting up the tray, side walls 15 are folded up along fold lines 16, their end flaps 17 are bent over on the fold lines 18 and the

gusset aps

19 and 23 are bent inward and on

lines

20, 24 and 18', all as shown n Fig. 2.. End iiaps 11 are now bent over the aps 17 and the semi-circular terminal flaps 13 are bent inwardly or downwardly, as shown in Fig. 5. A can may now be inserted between walls 15 and fold lines 14, as indicated in Figs. 3 and 4, until the bead of the can comes below the semicircular terminal flaps 13 and is engaged thereby for holding the can in the tray. By reason of the reverse folding of the gusset `

flaps

19 and 23 inside the

panels

17 and 15, a secure corner structure which will not move outwardly (parallel to flaps 17) is provided and the holding of these iiaps from moving outwardly endwise by the iiap 11 holds the entire structure together in a very firm and secure manner. The structure thus provides a tray which interlocks with a beaded can, holding the same securely, and in which no adhesive or interlocking aps are required, since the strength and rigidity f ice of the can itself hold the parts of the tray in the desired assembled relation.

The tray of the invention may be utilized in a variety of ways. In particular, it may be mounted adhesively or otherwise on the top of a package of ordinary rectangular form, or the top of two such packages, as indicated schematically by the phantom lines in Figs. 3 and 4.

What is claimed is:

1. A blank for forming a folding paper tray for holding a can or similar object comprising a rectangular iioor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its endsv and terminal end iiaps joined to the last said end panels by fold lines, the side wall panels and lateral end panels joined thereto having gus*- set structures forming continuations thereof and defined, in each case, by a ,continuation of the said diagonal fold line and by two further fold lines at an angle thereto, whereby the folding over of a said lateral end panel into perpendicularity with its side panel and the folding inward of the said gusset structure provides a substantially rigid corner structure.

2. A blank for forming a folding paper tray for holding a can or similar object comprising a rectangular iioor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its ends and substantially semi-circular terminal end aps joined to the last said end panels by fold lines, the side wall panels and lateral end panels joined thereto having gusset structures forming continuations thereof and defined, in each case, by a continuation of the said diagonal fold line and by two further fold lines at an angle thereto, whereby the folding over of a said lateral end panel into perpendicularity with its side panel and the folding inward of the said gusset structure provides a substantially rigid corner structure.

3. A blank for forming a folding paper tray for holding a can or similar object comprising a rectangular floor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its ends and substantially semi-circular terminal end aps joined to the last said end panels by fold lines, the side wall panels and lateral end panels joined thereto having gusset structures forming continuations thereof and dened, in each case, by a continuation of the said diagonal fold line and by two further fold lines at an angle thereto, whereby the folding over of a said lateral end panel into perpendicularity with its side panel and the folding inward of the said gusset structure provides a substantially rigid corner structure, and the said substantially semi-circular end flaps being of a width so as to fit the said gusset structures for holding thc same in position.

4. A folding paper tray comprising a rectangular floor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its ends and terminal end aps joined to the last said end panels by fold lines, the side wall panels and lateral end panels joined thereto having gusset struc` tures forming continuations thereof and defined, in each case, by a continuation of the said diagonal fold line and by two further fold lines at an angle thereto, the said lateral end panels being perpendicular to their side panels and the said gusset structure being folded in to provide substantially rigid corner structures, whereby a can fitting in the said tray and holding the said side panels under tension, will also hold the said terminal `end flaps in folded over relation against the said gusset struetures, preventing outward movement thereof.

5. A folding paper tray comprising a rectangular floor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its ends and substantially semi-circular terminal end flaps joined to the last said end panels by fold lines, the side wall panels and lateral end panels joined thereto having gusset strctures forming continuations thereof and defined, in each case, by a continuation of the said diagonal fold line and by two further fold lines at an angle thereto, the said lateral end panels being perpendicular to their side panels and the said gusset structures being folded in to provide substantially rigid corner structures, whereby a can fitting in the said tray and holding the said side panels under tension, will also hold the said terminal end flaps in folded over relation 4 against the said gusset structures, preventing outward movement thereof.

6. A folding paper tray comprising a rectangular oor panel, side panels at each side thereof and joined thereto by fold lines, lateral end panels joined to the said side panels by diagonal fold lines at the ends thereof, further central end panels joined to the bottom panel by fold lines at its ends and substantially semi-circular terminal end flaps joined to the last said end panels by fold lines, the side Wall panels and lateral end panels joined thereto having gusset structures forming eontinuations thereof and defined, in each case, by a continuation of the said diagonal fold line and by two further fold lines at an angle thereto, the said lateral end panels being perpendicular to their side panels and the said gusset structures being folded in to provide substantially rigid corner structures, whereby a can fitting in the said tray and holding the said side panels under tension, will also hold the said terminal endilaps in folded over relation against the said gusset structures, preventing outward movement thereof.
