STAND-UP DISPLAY TRAY AND PACKAGE USING SAME
Abstract
A package employing a stand-up tray provides a retail shelf
display with the largest surface of the package facing the
prospective buyer. In this upright position maximum label space or
viewing of the package contents is available. The top edges of the
sidewalls which define the tray cavity opening are inclined from a
taller end wall to a shorter end wall rather than being
perpendicular to the end walls. In its vertical position, the tray
rests on the taller end wall which is perpendicular to all other
walls and edges except the inclined sidewall edges. As a result,
the tray cavity's opening is flared for compact nesting of trays
before filling while giving a flat supporting surface for the
upright tray.

Description
FIELD OF THE INVENTION
This invention relates to trays for the packaging and display of
articles for retail sale. Particularly, the invention relates to
the display and packaging of food items including bakery products
such as cookies and the like.
BACKGROUND OF THE INVENTION
A large number of goods both in the food and non-food lines are
displayed or sold in one form of a tray or another. In almost every
instance the tray rests on its largest or base surface. However, in
this position the contents of the tray can be observed without
obstruction only from above. Also, to conserve space in retail
displays it is usually desirable to stack product filled trays
vertically. This stacking means that even using transparent trays
and wrappers only a small edge or side portion of the contents can
be seen; or, only a small edge portion of the package is available
for a label which the prospective buyer will see. However, when
viewed from above all of the contents of a tray can be seen when
transparent wrapping is used or a large surface is presented for
labeling. Accordingly, it is one object of the present invention to
provide a tray for a package which can be placed on a shelf so that
its entire contents may be seen, or so that its largest surface is
available for labeling.
Another object of the present invention is to provide a tray for a
package which will be stable as it stands on one of its narrow ends
on a shelf.
Still another object of the present invention is to provide a tray
for a package which will stand upright for displaying purposes and
will rest horizontally for opening and serving.
Yet another object of the present invention is to provide a tray,
which before being loaded with product, is compactly nestable and
will de-nest freely.
These and other objects accomplished by the present invention will
become apparent from the following summary of the invention and the
detailed description of a preferred embodiment with reference to
the drawings.
SUMMARY OF THE INVENTION
In the broadest aspect, the present invention is a stand-up display
tray and package using same. Maximum label space is available and
full viewing of package contents is possible when a tray is placed
on a shelf in an upright manner. The top edges of the sidewalls and
end walls of the tray form a periphery which defines the tray
cavity opening. This periphery lies in a plane inclined with
respect to the base wall of the tray, the base wall being the
supporting surface for the tray contents when the tray is in a
horizontal position. The inclined opening or cut surface of the
tray makes possible a flared cavity opening for compact nesting of
the trays before they are filled while also permitting a right
angle between the taller end wall (bottom supporting surface in an
upright position) and the base wall (bottom supporting surface in a
horizontal position).
In another aspect, the invention is a molded, one piece, display
tray having at least one cavity for receiving a product. The tray
comprises a base wall, two end walls rising from the base wall, and
two side walls joining the two end walls. One of the end walls is
taller than the other and the sidewalls slope from the height of
the taller end wall to the height of the shorter end wall. The
taller end wall is approximately perpendicular to the base wall and
this taller wall serves as the bottom of the tray when the tray is
in a vertical, upright position. The shorter end wall is preferably
inclined away from the taller end wall to provide a flare at its
end of the tray. The upper edges of the end walls and the side
walls are joined and form a continuous edge which defines the
opening to the tray cavity. This edge defining the opening of the
tray cavity will lie in a plane which is at an acute angle with the
plane of the base wall. This means that the plane of the taller end
wall will make an angle of greater than 90.degree. with the plane
of the wall edges when the angle is measured counterclockwise from
the taller end wall.
In a more limited aspect the present invention comprises a tray as
described above which includes a peripheral flange around the
opening to the tray cavity. This peripheral flange extends
outwardly from the walls.
In a still more limited aspect, the present invention is a package
employing the above described tray having a product loaded into the
tray cavity. The wrapping material for the package encloses the
tray and the product and the wrapping material is in the form of a
bag or tube which is closed by having an upper and lower sealed
seam. To enable the package to stand upright on the shelf the seam
is folded under the flange extending from the taller end wall of
the tray thus providing a stable base for the package as it stands
upright.
The trays of the subject invention may be formed from any clear or
opaque materials which lend themselves to molding. Typical of such
materials are paper, plastics, and metal. Preferred paper materials
would be pulp and fiberboard; preferred plastic materials are the
thermoplastics including polystyrene, polyesters, polyolefins, and
polyamides; and, preferred metals are aluminum and steel foil.
Trays and packages within the scope of the invention may be single
or multi-compartment and of varying depth, width, or dimensional
configuration. The invention contemplates the packaging of both
food and non-food items. A particularly advantageous utilization of
the subject invention in the food line is with bakery products such
as cookies and the like. However, the invention is also useful for
the packaging and display of cheese, fresh or frozen meat cuts, and
poultry in whole or in piece.
A better appreciation of the subject invention can be had from the
drawings and the following detailed description.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment of the subject invention is shown in FIGS.
1 through 8 and the following description will refer to those
figures. In this embodiment, the tray cavity has been divided into
three compartments of relatively equal size and the compartments
are designed for receiving disc shaped bakery items such as
cookies.
FIG. 1 is a side elevation of the cookie package of the preferred
embodiment. Tray 1 is enclosed in wrapping material 2 which is in
the form of a bag having a lower seam 14 and an upper seam 13. FIG.
2 is a front view of FIG. 1 showing the lower compartment 4, the
middle compartment 5. and the upper compartment 6, all of which
contain the product or cookies 3.
Referring now to FIGS. 3 through 5, the cut line or upper
peripheral edge 8 of the walls is seen. Extending outwardly from
this upper peripheral edge 8 is flange 10. The flange width may
vary around the tray periphery depending on cavity arrangement.
From flange 10, flange wall 11 rises. The top edge of flange 11 is
approximately parallel to the upper edge of the tray opening 8. In
this embodiment grooves 7 are provided for receiving the cookies
and for strengthening the walls. The tray base line of bottom wall
12 is also the taller of the two end walls which define the ends of
the tray as it lies in its horizontal position as shown in FIGS. 3
through 4. Indentations 15 are provided at the juncture between
flange 10 and the walls defining the cavity of the tray. These
indentations 15 enable a stacked group of the trays to de-nest
freely. From the top, the de-nesting members 15 appear as
indentations but from the bottom and side of the tray they appear
as projections. When stacked, the projections of one tray rest on
the flange of the tray immediately below. The projections are
staggered so that they are not in the same place for succeeding
trays. These projections and corresponding indentations 15 serve to
keep the surfaces of stacked trays separated so that partial vacuum
will not be formed thus hindering separation of the trays.
FIG. 7 is an enlarged view in partial section of a package similar
to that shown in FIG. 1, the view in both instances being from the
side. FIG. 6 is a related view of a tray in essentially the same
position as the tray shown in FIG. 7 but in FIG. 6 the product or
cookies 3 and the overwrapping or bag 2 is missing. Line 9 shown in
both figures is the edge of the base wall plane which serves as the
supporting surface of the tray cavity when the tray is in a
horizontal position such as shown in FIG. 4. The base wall plane 9
is perpendicular to the plane of the taller end wall 12 and when in
the position shown in FIG. 6 this base wall plane 9 will not be
perpendicular to the surface on which the tray rests due to the
projection of flange 10. Thus, base wall plane 9 varies from
perpendicular by a small angle .theta.. In FIG. 7 the bag 2 is
shown with its seam 14 folded under the taller end wall 12. This
seam compensates for the angle .theta. and enables the package to
stand upright perpendicular to the shelf or other supporting
surface. As can be seen from FIG. 7, the package rests on the seam
14 and on the flange 10. As various packaging materials are used
the width of flange 10 will have to be varied to compensate for the
thickness of the seam 14. Thus, the center of gravity (CG. in FIG.
1) of the package is symmetrically located with respect to the
package's supporting surface.
In FIGS. 4 and 8 an essential feature of the subject invention can
be appreciated. FIG. 8 shows a stacked array of the trays of the
preferred embodiment. In order to provide a flat surface against
which seam 14 (see FIG. 7) may rest, taller end wall 12 must be
approximately perpendicular to base wall plane 9. However, if
taller end wall 12 is also perpendicular to cut line 8 (the plane
of the upper edge of the side walls) to form a rectangularly shaped
tray, then there can be no compact nesting of the trays as shown in
FIG. 8. In other words, there must be a flared opening in order for
there to be nesting. Accordingly, it has been surprisingly found
that such a flared opening may be provided by sloping the cut line
8 away from the horizontal at an acute angle .PHI.. The angle .PHI.
is shown measured from two different points of reference, one as
shown in FIG. 4 and the other as shown in FIG. 8. As shown in FIG.
4, the cut line or the plane containing the edge defining the
opening of the tray cavity 8 is at an angle greater than 90.degree.
from the plane of the taller end wall 12 when the angle is measured
counterclockwise. The angle is greater than 90.degree. by the acute
angle .PHI.. FIG. 8 clearly shows how the provision of the sloping
cut line 8 enables the end wall 12 to be perpendicular to the base
line 9 and at the same time an opening flared by the amount
represented by the angle .PHI. is provided. In this embodiment,
.PHI. is approximately 8.degree..
In the preferred embodiment, compartment or intermediate walls 16
and 17 are formed by indentations in base wall 9 (See FIGS. 3 to 5)
which connect side walls 18 and 19. These intermediate walls divide
the tray cavity and define the three compartments 4, 5, and 6.
ALTERNATE EMBODIMENT
FIGS. 9 and 10 illustrate an alternate embodiment of the present
invention. FIG. 9 is a side view and FIG. 10 is a front view. Tray
31 which is filled by product 33 is overwrapped or enclosed in bag
32 having upper seam 35 and lower seam 36. Flange 37 extends
outwardly from the cut line 34. The cut line 34 also defines the
opening to the tray cavity. End wall 38 is at right angles to base
wall 39 and angle .PHI., the angle of slope of the cut line 34,
provides a flared opening for compact nesting of the trays. In a
tray shown in FIGS. 9 and 10, products such as cake, cheese, meats
cuts, or even whole chicken can be packaged and displayed.
Angle .PHI. may vary from being as small as 3.degree. or 4.degree.
to as much as 25.degree. to 30.degree. depending upon the tray
configuration. Preferably, the range of use will vary between
5.degree. and 15.degree..
