Abstract
A package for holding a plurality of articles such as fruit for
shipment, storage and display comprising a tray having a plurality
of downwardly dished article holding pockets and a plurality of
upwardly tapering posts dispersed between the pockets and arranged
so that when one tray is stacked upon another then the pockets of
the upper tray are supported by the posts of the lower tray so that
the upper tray does not rest on the articles in the pockets of the
lower tray. The package further has a cover which is latticed or
grid-like including parallel rows of windows separated by
strip-like portions, the windows affording a view of the articles
in the pockets for display purposes and permitting another tray to
be stacked thereon for shipment or storage purposes. In one
embodiment, the windows are centered above the posts whereby the
pockets of a tray stacked thereupon extend down through the windows
for direct contact with the posts, and in another embodiment the
intersection of the strip-like portions contact the tops of the
posts whereby the pockets of a tray stacked thereupon rest on such
portions for support by the posts. The cover may be hingedly
connected to the tray, or the two may constitute independent parts,
but in each case latching means is provided to releasably secure
the cover to the tray in a closed condition to retain the articles
in the pockets.

Description
BACKGROUND OF THE INVENTION
The claimed invention relates to the field of articles designed for
the shipment, storage and display of articles such as fruit, and
more particularly to a stackable package having a tray with pocket
and post configuration and a cover with windows to afford a view of
the articles in the pockets.
Prior to the present invention, no package for individual articles,
such as fruit, was available with a cover designed to hold the
fruit in the pockets but which permitted a view of the contents of
the package and was also capable of being stacked with like
packages in a manner which did not transmit stacking forces on the
packaged articles. The standard pocket and post trays with closable
covers, such as molded egg cartons, are stacked in a manner wherein
the bottoms of the pockets of one tray rest on the flat portion of
the cover of the tray therebelow in a manner which positions the
pockets directly over the articles in the pockets of the lower
tray. With this arrangement, since the flat portion of the cover
member is relatively thin and quite flexible, the pockets of the
upper tray impose destructive crushing forces on the articles in
the pockets of the lower tray.
With the previously known deep pocket trays for articles such as
fruit, on the other hand, the stacking problem has been overcome by
arranging the pockets and posts of the tray in such a manner that
when one tray is oriented 180.degree. (or, in some cases,
90.degree.) with respect to another tray they may be stacked in a
manner which places the bottoms of the pockets of the upper tray on
the tops of the posts of the lower tray, and the upper tray does
not make substantial contact with the articles in the pockets of
the lower tray. But this arrangement has heretofore been confined
to open trays without covers to hold the articles in the pockets,
which is a drawback when the trays full of articles are handled on
an individual basis.
Thus, the problem heretofore unsolved in the prior art is the
provision of a package for a pocket and post tray with a cover to
retain articles in the pockets and which may be stacked with
similar packages in a manner which avoids all tendencies to impose
crushing forces on the packaged articles.
SUMMARY OF THE INVENTION
This invention provides a covered package for holding a plurality
of articles for shipment, storage and display comprising a tray
having a plurality of downwardly dished article holding pockets, a
plurality of upwardly tapering posts dispersed between the pockets,
the pockets and posts being arranged so that when one tray is
stacked upon another the pockets of the upper tray are supported by
the posts of the lower tray and the upper tray does not make
substantial contact with the articles in the pockets of the lower
tray. This is accomplished by a cover which is characterized by a
grid-like arrangement providing a plurality of windows which afford
a view of the articles in the pockets. The grid-like arrangement
includes parallel rows of windows separated by strip-like portions
the intersections of which are located above the articles in the
pockets and which do not interfere with the stacking features. In
one embodiment, the windows are centered above the posts whereby
the pockets of a tray stacked thereupon extend down through the
windows for direct contact with the posts, and in another
embodiment the strip-like portions contact the top of the posts
whereby the pockets of a tray stacked thereupon rest on such
portions for support by the posts. The cover may be hingedly
connected to the tray, or the two may constitute independent parts,
but in each case latching means is provided to releasably secure
the cover to the tray in a closed condition to retain the articles
in the pockets.

DETAILED DESCRIPTION
The package 10 according to this invention as illustrated in FIGS.
1 through 3 comprises a tray 12 having a plurality of downwardly
dished pockets 14 adapted to hold individual articles 16 such as
fruit -- and particularly fruit of a delicate nature such as the
peaches illustrated in the drawings. The tray 12 further has a
plurality of upwardly tapering posts 18 dispersed between the
pockets. The bottoms 20 of the pockets lie in a common flat plane,
and the tops 22 of the posts also lie in a common flat plane
parallel with but spaced above the plane of the pocket bottoms 20.
The pockets and posts are arranged so that when one tray is rotated
180.degree. with respect to another tray it may be stacked on top
thereof in a manner which causes the bottoms 20 of the pockets 14
of the upper tray to be supported by the tops 22 of the posts 18 of
the lower tray.
The package 10 further comprises a cover 24 having downwardly and
outwardly flaring side walls 26 and end walls 28. A grid-like
arrangement spans the upper portions of these walls to provide a
plurality of windows 30 which afford a view of the articles 16 in
the pockets 14 for display purposes, and which permit another tray
to be stacked thereon as aforesaid for shipment and storage
purposes. The grid-like arrangement includes parallel rows of
windows 30 arranged diagonal to the side and end walls and
separated by strip-like portions 32 including portions 34 located
above the articles 16 in the pockets to retain the articles
therein. The article retaining portions 34 are formed by
intersection of the strip-like portions 32. The strip-like portions
32 occupy a substantially flat plane, and the windows 30 are
centered above the tops 22 of the posts 18 of the tray. This
permits the bottoms 20 of the pockets 14 of an upper tray in a
stack to extend down through the windows 30 in the cover of a lower
tray for direct contact with the tops 18 of the posts 14 of the
lower tray to be supported by them.
The cover 24 and tray 12 are connected to each other along the rear
side by a hinge 36, and latching means 38 are provided to
releasably secure the cover in the closed condition. When the cover
is thus secured, the portions 34 of the grid-like arrangement
retain the articles 16 in the pockets and the windows 30 provided
by to strip-like portions 32 permit post to pocket support of
properly oriented trays in a stack.
Another embodiment of this invention is illustrated in FIGS. 4
through 6 wherein the package 40 comprises a tray 42 having a
plurality of downwardly dished pockets 44 adapted to hold
individual articles 46. The tray 42 further has a plurality of
upwardly tapering posts 48 dispersed between the pockets. The
bottoms 50 of the pockets lie in a common flat plane and the tops
52 of the posts also lie in a common flat plane parallel with but
spaced above the plane of the pocket bottoms 50. The pockets and
posts are arranged for stacking as in the embodiment of FIGS. 1
through 3.
The package 40 further comprises a cover 54 having downwardly and
outwardly flaring side walls 56 and end walls 58. A grid-like
arrangement spans the upper portions of these walls to provide a
plurality of windows 60 which afford a view of the articles 46 in
the pockets 44 for display purposes, and which permit another tray
to be stacked thereon for shipment and storage purposes. The
grid-like arrangement includes parallel rows of windows arranged
parallel to the side and end walls and separated by strip-like
portions 62 including portions 64 located above the articles 46 in
the pockets to retain the articles therein, and other portions 66
located above the tops 52 of the posts 48. The article retaining
portions 64 and post spanning portions 66 are formed by
intersection of the strip-like portions 62. The strip-like portions
62 are recessed at the portions 66 to substantially the level of
the tops 52 of the posts 48. This permits the bottoms 50 of the
pockets 44 of an upper tray in a stack to rest on the portions 66
which in turn rest on the tops 52 of the posts of the lower tray to
be supported by them.
The cover 54 and tray 42 are independent parts provided with
latching means 68 to releasably secure them together in the closed
condition. When the cover is thus secured, the portions 64 of the
grid-like arrangement retain the particles 46 in the pockets and
the portions 66 are recessed to permit post to pocket support of
properly oriented trays in a stack.
