[0001] This invention is concerned with trays and more particularly with packing trays used
to protect and separate items being shipped in cartons, or boxes, for example.
[0002] At one time many delicate items such as fruit, were shipped in burlap bags. Thus,
for example, citrus fruits were packed in burlap bags for shipment. Soon it became
apparent that the damage to the fruit during shipment in this manner was extensive.
Accordingly it was found that it was economical to ship the delicate fruit in boxes
and/or cartons. The money saved by avoiding damage to the fruit more than paid for
the cartons. Subsequently it was found that if the fruit was separated during the
shipment by first putting the fruit in trays and then packing the trays in the carton,
a further significant reduction in the amount of damage was effected. Therefore, it
was economical to provide such packing trays.
[0003] Generally such prior art packing trays comprise a main body section having a plurality
of receptacles such as partial cup sections in the main body of the tray for receiving
the individual fruits. The trays must be inexpensive, accordingly they are generally
made of thin material which bends easily. The trays, in fact, tend to bend when the
fruit is in the tray and the tray is being transferred to the cartons. Thus, there
is a long-standing problem when using such trays. The problem is the inherent difficulty
of placing the loaded trays into the cartons or boxes. The same problem arises when
removing the loaded trays from the boxes.
[0004] A solution in the prior art has been to make the trays of a more substantial material
and provide integral finger grips on the sides of the trays. However this solution
has not proved generally feasible. For one thing, it is clumsy to insert the trays
into the boxes using the integral finger grip arrangement. Also it is clumsy to remove
the trays using the finger grip arrangement. Further the finger grip arrangement is
only feasible, if at all, when the tray itself is of a sufficiently rigid material
or sufficiently thick to provide rigidity for supporting the fruit. Thus when using
such finger grip equipped trays less fruit can be packed within the same cubic volume
and more expensive trays are required. Since shipping charges are generally based
on volume, this adds significantly to the expense of the shipping.
[0005] Accordingly, there has been a long standing need for some means to facilitate handling
such trays without decreasing the number of fruit per unit volume that can be shipped.
[0006] Accordingly it is an object of the present invention to provide new and improved
packing trays in which the above referred to disadvantages are substantially reduced
or overcome and the above referred to features are substantially attained.
[0007] According to the present invention an improved packing tray is provided, said tray
comprising:
main body means,
said main body means including receptacle means for retaining articles for packaging,
and
handle means external to said main body means,
said handle means coupled to said main body means to maintain the dimensions of said
main body whereby said main body means with said handle means can fit into packages
in the same manner as without handles.
[0008] A feature of the invention provides external handle means that are planar and extremely
flexible.
[0009] A further feature of the invention provides such external handles at the longitudinal
ends of the main body means.
[0010] Yet another feature of the invention provides such external handles at the sides
of said main body means.
[0011] Yet another feature of the invention uses handles characterized so that packed trays
with the handles do not interfere with ventilating openings in the cartons.
[0012] Still another feature of the invention provides handle means that are solid and planar
while a further feature of the invention provides planar handle means that have cut-outs
therein for receiving the user's hand in the handles.
[0013] The operation and utilization of the present invention will be more fully apparent
from the description of a preferred embodiment taken in conjunction with the following
drawings, in which:
Fig. 1 is a pictorial showing of a preferred embodiment of the improved packing tray
with external handles,
Fig. 2 is a side view of the tray of Fig. 1,
Fig. 3 shows the trays as packed in cartons, and
Fig. 4 shows another embodiment of the handle means.
[0014] The packing tray 11 as shown in the drawings is a plastic embodiment used in packing
citrus fruits. However, it should be understood that while this embodiment is described
in an exemplary fashion herein, such description is not a limitation on the scope
of the invention. Thus the packing trays can be used for goods other than citrus fruits.
Similarly, material other than plastic with which to fabricate the trays can also
be used within the scope of this invention.
[0015] The plastic tray 11 comprises a main body section 12. The main body section has therein
a plurality of receptacles such as receptacle 13 for receiving the products to be
packaged. It also has slightly raised border therearound shown as border 14. The material
used for packaging of fruit in this preferred embodiment is a very thin PVC material
in the order of 1/10 to 3/10 of a mm of thickness. The main body section is also shown
to have therein ventilating holes such as hole 16 to assure ventilation throughout
the package. Drainage holes (not shown) for condensation or other fluids may also
be provided at the bottoms of the receptacles.
[0016] Integral to the main body sections are means for handling the transporting the packaging
tray when loaded with the articles to be packages. More particularly two wings or
handles 17 and 18 are provided, one on either longitudinal side of the main body.
The handles are shown as having a trapezoidal shape. This shaped handle enables the
handles when turned up in the cartons such as shown in Fig. 3 to remain clear of ventilating
holes normally placed in the cartons to assure constant ventilation of the fruit within
the carton, for example. If the devices held in the packing are devices that do not
require ventilation then the holes in the main body are not required.
[0017] When the packing tray comes out of the mold with the integral handles thereon they
arenormally in the position shown in Figs. 1 and 2. However by making scoring lines
such as shown at 19 and 21 for handles 17 and 18 respectively, the handles then assume
a position normal to the main body such as shown in dashed line form in Fig. 1 at
17a and 18a.
[0018] The upstanding position of the handles 17a and 18a provides a synergistic benefit
for the packing tray with handles. Oftentimes, the trays are automatically filled.
They are sent on a conveyor to be automatically loaded with fruit. The prior art trays
without handles tend to climb over each other rather than push each other along as
intended. The handles assure that there is no climbing and that the trays move as
intended.
[0019] Fig. 3 shows the trays in a packing carton. The packing carton is designated as carton
22. In it there is located the tray 11 having a main body 12, receptacles 13, a border
14 and side handles 17 and 18 which are held by the carton in a position normal to
the main body 12. Because of the thinness of the material used, the handles take up
almost no room. Similarly the handles use very little material during molding of the
trays.
[0020] The articles to be packed are shown as oranges such as orange 23. Stacked on top
of the first tray full of oranges is a second tray having a main body 24, a border
or abutment region 26, receptacles such as 27 and handles 28 and 29. Note that the
handles of the stacked trays overlay each other.
[0021] The trapezoidal shape of the handles assures that the handles do not cover the ventilating
holes normally placed in the cartons when fruit is packed. Note that a plurality of
trays loaded with the articles can be stacked one on top of the other without the
handles taking any room and still being in a position to aid a person in removing
the trays from the carton.
[0022] Fig. 4 shows another embodiment 31 of the handle. In this embodiment the handle has
an arcuate shape with a space 32 therein to enable the fingers to encircle the outer
section 33 of the handles. The space.separates the outer section 33 from the inner
section 34 which is integral to the main body 36.
[0023] Many different shapes can be utilized within the scope of the invention. The key
thing is that the handle does not interfere with the packaging but enables the packers
to handle the packing trays with greater facility and ease. In addition the handles
take up almost no room, cost almost nothing since they simply are part of the same
molding process which makes the trays.
[0024] In use the handles are made external to the main body but integral thereto. The handles
are either extremely flexible or are inherently positioned normal to the main body
so as not to take up any room or any additional volume when packing the trays having
the goods therein. These trays with the handles are ideal for automatic loading since
the handles prevent one tray from climbing on another and thus implement the use of
the trays for the automatic loading by assuring that one empty tray pushes the next
empty tray along. When the trays are loaded the packer merely lifts the tray using
the external handles and places the tray in the open carton.
[0025] While the handle is in the preferred embodiment shown at the longitudinal ends, the
handle can also be placed on the shorter ends or sides of the packing tray within
the scope of this invention.
[0026] While the principles of the invention have been described above in connection with
specific apparatus and applications, it is to be understood that this description
is made by way of example only and not as a limitation on the scope of the invention.
