17 Qlaims. (Cl. 99-171) This invention relates to produce packaging and more particularly to an improved tray or container for holding small quantities of pears for retail display and distribution.

There is a need in the retail merchandising of pears in fruit markets, supermarkets and the like for a container which will hold a small quantity of pears, such as a half dozen, for example, for retail sale as a packaged unit. In displaying pears for retail sale, it is desirable that the cavity at the calyx end of the pears be concealed since the appearance of this cavity is aesthetically unpleasant and diminishes the sales appeal of the pears. While pear containers are known in the prior art, none of those of which we are aware are so constructed as to conceal the cavity at the calyx end of the pear.

It is also desirable that the pear tray be so constructed as to permit nested stacking of the trays when loaded with pears and also nested stacking of trays when in unloaded condition. l

Accordingly, it is an object of this invention to provide a tray for the retail display and distribution of pears which provides an aesthetically pleasing display tending to promote the sale of the pears.

It is another object of this invention to provide a pear tray which is so constructed as to conceal the cavity at the calyx end of the pears supported by the tray.

It is still another object of this invention to provide a retail container or tray for pears having improved stacking characteristics both when loaded and unloaded.

In achievement of these objectives, there are provided in accordance with this invention several different embodiments of pear trays, preferably made from molded pulp, and each including a plurality of molded pearshaped recesses. Each pear-shaped recess includes an enlarged recess portion for receiving the calyx end of the pear and a communicating narrower recess portion for receiving the stem end of the pear. Each pearreceiving recess is inclined upwardly from the calyxreceiving portion to the stem-receiving portion so that the stem of the pear is elevated above the calyx end of the pear. The surfaces of the recess are so dimensioned and contoured that the cavity at the calyx end of the pear is concealed. The upwardly inclined surface of the pear-receiving recess causes the calyx end of the pear to be rotated downwardly, permitting the outer Wall of the calyx-receiving end of the recess to conceal the cavity at the calyx end of the pear. The plurality of upwardly inclined pear-shaped recessesslope upwardly toward the center of the tray with a resulting cone-shaped apex or apexes on the underneath surface of the container which facilitate nesting of the containers both in loaded and in unloaded condition.

Other objects and the nature and advantages of the instant invention will be apparent from the following description taken in conjunction with the accompanying drawings, wherein:

Fig. 10 is a view in vertical section along line 10--10 of Fig. 9, additionally showing a fragmentary view of a second similar tray in superposed relation to the tray of Fig.v 9.

Referring now to the drawings, and more particularly to the views of Figs. 1 and 2, there is shown a pear tray generally indicated at 20, preferably formed of molded pulp, including a rectangular body portion 22 having six spaced open top pear-shaped molded recesses indicated at 24, 26, 28, 30, 32 and 34, respectively. Each of the pear-receiving recesses is alike, and recess 26 will be referred to as a typical recess. Each of the recesses includes an enlarged portion such as that indicated at 36 in recess 26 for receiving the calyx end of the pear. At its opposite end each recess is provided with a narrow neck portion indicated at 38 in recess 26 for receiving the stem end of the pear. The calyx-receiving portion of each recess is disposed adjacent an outer longitudinal edge of the tray while the stem-receiving portion is disposed adjacent the central longitudinal axis of the tray.

In accordance with an important feature of the invention, each molded recess is so shaped that the stem end of the pear is supported at a level above that of the calyx end of the pear so that the pear axis, which is hereby defined to extend from the calyx to the stem end of the pear, is at an inclination to the horizontal plane as best seen in the view of Fig. 2. To accommodate the arcuate contour of the pear, the molded wall of recess 26 curves downwardly in wall portion 40 from the inner boundary of flange portion 41 which forms the outer peripheral edge of body 22. The curved wall of recess 26 reaches its lowest level at 42 and then curves upwardly in a relatively sharp incline as indicated at 44. The inclination of wall portion 44 is such as to tilt the pear axis at an angle which raises the stem end of the pear above the calyx end of the pear and causes the upper surface of the pear, and the axis of the pear, to be inclined upwardly toward the central longitudinal axis of the tray.

An important advantage of the construction shown in the embodiment of Figs. 1 and 2, which is also true of all of the other embodiments of the invention described in this application, is the fact that the inclination of the wall portion 44 which elevates the stem end of the pear above the calyx end of the pear cooperates with the downwardly extending outer wall portion 40 of the recess to position the cavity C at the calyx end of the pear in such manner that the cavity C is hidden from view, thereby making the display of the pears aesthetically pleasing and improving the sales appeal of the pears.

In the embodiment of Figs. 1 and 2, each of the

recesses

24, 26, 28, 38, 32 and 34 is positioned so that the horizontal projection of its calyx-stem axis is perpendicular to the central longitudinal axis of the tray. Three of the pear-receiving

recesses

24, 26, 28 lie on one side of the central longitudinal axis of the tray. Each recess on one side of the longitudinal axis is positioned directly opposite a corresponding recess on the opposite side of the longitudinal axis. Thus,

recesses

24 and 39, 26 and 32, and 28 and 34 are respectively oppositely disposed to each other. The calyx-stem axis of each recess lies in a common plane transverse to the longitudinal axis of the tray with the calyx-stem axis of its corresponding oppositely disposed recess.

As best seen in the view of Fig. 2, each pair of oppositely disposed recesses such as 24 and 30, 26 and 32, and 2 3 and 34 incline upwardly toward each other and toward the central longitudinal axis of the tray to define a generally conical hollow recess 35 on the underneath of the tray having an apex such as that indicated at 37 between the

pear'shaped recesses

26 and 32. This construction permits two or more loaded trays to be stacked in superimposed nested relation to each other, as shown in Fig. 2, with the elevated stem portions of each pair of oppositely disposed pears of the lower tray such as those in

recesses

26 and 32, for example, being received in the lower portion of the hollow recess 35 of the tray above. Thus, successively superimposed loaded trays are in effect physically interlocked with each other to thereby resist any tendency of the superposed trays to become dislodged and providing a firm and stable stacking arrangement. downwardly inclined projections such as 26 permit a plurality of unloaded trays to be stacked in nested relation to each other in a minimum of space. There is shown in Figs. 3-6 a modified pear tray generally indicated at 58, preferably made of molded pulp, and including a rectangular body portion 52 and a plurality of pear-shaped recesses indicated at 54, 56, 58, 6t), 62, 64, respectively. The contours of. the individual recesses are similar to those of the recess 26 previously described and will not be described again in detail. As in the case of the recess 26 of tray 20, each of the recesses of tray t! is so shaped as to elevate the stem end of the pear above the calyx end of the pear so that the cavity at the calyx end of the pear is concealed from view.

The calyx-stem axis of each recess of tray 50 lies in a vertical plane perpendicular to the horizontal plane in which the longitudinal axis of the tray lies, and intersecting the longitudinal axis at an angle, such as the angle of approximately 45 degrees shown in the embodiment of Figs. 36. Expressed in a different manner, the horizontal projection of the calyx-stem axis of each of the

recesses

54, 56, 58, 60, 62, 64 intersects the longitudinal axis of the tray lying in a horizontal plane at an angle of substantially 45 degrees. The calyx-receiving portion of each recess is disposed toward the outer longitudinal edge of the tray, while the stem-receiving portion of each recess is disposed adjacent the central longitudinal axis of the tray.

Recesses 54, 56, 58 all lie in one row with their respective stem ends rotated substantially 45 degrees in a counterclockwise direction from a perpendicular relation with respect to the longitudinal axis of the tray. Recesses 6d, 62, 64 all lie in a second row and have their respective stem ends rotated substantially 45 degrees in a counterclockwise direction from a perpendicular relation with respect to the longitudinal axis of the tray. Due to the angularly arranged position of the opposite rows or pear-receiving recesses as just explained, the tapered neck portion adjacent the stem end of each recess lies contiguous to but spaced from a similar portion of the Furthermore, the plurality of oppositely disposed recess and in generally complementary relation thereto. Thus, the tapered neck portions of the respective oppositely disposed recesses 5460, 56-62, and 53-64 lie contiguous to and in generally complementary relation to each other. Also, the pear axes of

recesses

54 and 62 lie in a common vertical plane angularly transverse to the horizontal longitudinal axis of the tray and the axes of

recesses

56 and 64 lie in another common vertical plane angularly transverse to the horizontal longitudinal axis of the tray. The angular arrangement of the recesses just described permits the longitudinal and transverse dimensions of the tray to be made smaller for a given number of recesses of a given size.

In the embodiment of Figs. 7 and 8, there is shown a pear tray generally indicated at 70, preferably made of molded pulp, and including a generally rectangular body member 72 having six molded pear-shaped

recesses

78, 88, 82, 84, 86 and 88 which radiate from a central point defined by the intersection of the central longitudinal and transverse axes of the tray. The shape of each recess is similar to that of recess 26 decribed in connection with the embodiment of Figs. 1 and 2 and is so shaped as to elevate the stem of the pear above the calyx end of the pear to conceal the cavity at the calyx end of the pear.

The two recesses 8d and 36 have the horizontal projections of their respective calyx-stem. axes perpendicular to the central longitudinal axis of the tray, while the

other recesses

78, 82, 84, 88 have the horizontal projections of their respective calyx-stern. axes inclined at an angle of substantially 45 degrees with respect to the longitudinal axis of the tray and in alignment with the four

outer corners

79, 83, 85, 89 of the tray.

Recesses

78, 80, 82 lie in a single row on one side of the central longitudinal axis of the tray, while

recesses

84, 86, 88 lie in a single row on the opposite side of the central longitudinal axis of the tray.

Recesses

78 and 82 are respectively rotated in a counterclockwise and a clockwise direction with respect to the perpendicularly positioned recess and into alignment with the

respective corners

79 and 83 of the tray.

Recesses

84 and 88 are respectively rotated in a clockwise and a counterclockwise direction with respect to the perpendicularly positioned recess 86 and into alignment with the respective corners and 89 of the tray.

The construction of the trays shown in Figs. 7 and 8 facilitates nested stacking of the loaded trays. The two

central recesses

80 and 86 converge toward each other and toward the central longitudinal axis of the tray to define a generally conical recess 80 (Fig. 8) on the underneath of the tray having an apex 90 which permits the pears in. a lower tray to be received in nested relation within the recess 89 of an upper tray. In a generally similar manner, the adjacent stem ends of each pair of recesses '7884 and 82-88 define hollow recesses on the underneath surface of the tray which facilitate nested stacking of the loaded trays. The nested stacking provided by this construction in effect interlocks two superposed loaded trays to resist dislodgernent of the two trays with respect to each other, thereby providing a more stable stacking arrangement. The construction of the trays of Figs. 7 and 8 also permits nested stacking when unloaded since the corresponding pear-receiving recesses of each tray nest into those of the superposed trays above and below it to permit a maximum number of unloaded trays to be stacked in a given height.

There is shown in Figs. 9 and 10 a pear tray generally indicated at 100, preferably made of molded pulp, having a body member 102 of substantially hexagonal perimeter. The hexagonal outer perimeter of tray permits a plurality of similar trays to be positioned in side-by-side relation on a fruit stand with a maximum utilization of the available display space. Tray 100 includes a plurality of pear-shaped molded

recesses

104, 106, 108, 110, 112.

114, respectively. Each of the recesses is similar to those previously described, such as recess 26 of the embodiment of Figs. 1 and 2, and is so shaped as to elevate the stem end of the pear above the calyx end of the pear to conceal the cavity at the calyx end of the pear. The six pear-shaped recesses radiate outwardly like the spokes of. a wheel from the center of the tray, the stem-supporting end of each recess being positioned adjacent the central axis of the tray and likewise adjacent the stem ends of all of the other outwardly radiating recesses.

As best seen in Fig. 10, the construction of tray 100 permits superposed stacking of the loaded trays. The plurality of converging stem-receiving recess portions define a generally conical hollow recess indicated at 116 in Fig. into which the stern ends of the pears supported by a lower tray can nest. This provides an interlocking engagement between the pears of the lower tray with the hollow conical portions of the tray above it, to resist shifting movement of the trays with respect to each other, thereby providing a stable stacking arrangement. The plurality of downwardly extending pear-receiving recesses also adapt the unloaded trays to be nested in stacked superposed relation to permit a maximum number of the unloaded trays to be stacked in a height.

it can be seen from the foregoing that there are provided in accordance with this invention various embodiments of pear trays which permit pears to be displayed for sale in an aesthetically pleasing manner, since the trays are all so constructed as to conceal the unsightly cavity at the calyx end of the pear. Furthermore, the trays permit nested stacking of loaded trays in a more stable manner than heretofore possible with trays of the prior art, as well as permitting nested stacking of the unloaded trays.

It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
