Claims
1. I claim a rectangular, translucent, plastic tray, vacuum formed
with a flat bottom, surrounded by four sides, slanted out from the
base, with each side forming a trapezoidal shape, and with the rear
side being considerably larger that the front, while both the right
and left side are of equal shape, with all four side blending to
form an arrow shaped tray.
2. I claim a tray, as described in claim 1, which has several,
large, recesses at the bottom corner of the rear side and the rear
bottom allowing a volume and edge large enough to allow four
fingers of the hand to fit as the thumb of the same hand clamps the
tray, holding it steady by the top, rear edge.
3. A tray, as described in claims 1 and 2, which also has four
exterior depressions, with two on the front edge and two on the
rear beveled side, allowing a means of multiple stacking of trays
within each other, up to 12.
4. A tray, as described in claims 1, 2 and 3 which has a non-skid
material permanently bonded to its underside.
5. A tray, as described in claims 1, 2, 3, and 4 which has several
embossed windows, limited by an edge integrally formed, allowing
directional labeling instruction and display.
6. A tray, as described in claim 1, 2, 3, 4, and 5 which has a
raised pad, allowing placement and bonding of a wedge with multiple
steps, as a testing sample for the X-ray machine.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to a hand held container, made
of translucent plastic, incorporating several useful features. This
invention improves the way passengers depose pocket objects and
smaller carry-on objects, such as cameras into the tray, to be
inspected by X-ray while traveling on a conveyor, used at all
airports, international railroad stations and Custom's border
posts. Such a tray can also be useful for governmental areas or
research areas to decrease security risk. In these times when we
fear terrorists attacks and are faced with illicit drug
trafficking, along with the congestion found at airports around the
world, an efficient, rapid inspection through these X-ray machines
is not usually the case. Normally, long lines and waits are usually
encountered. The inventor's objective is to improve upon this
security operation by allowing inspectors to have a large enough
tray to handle all of the pocket objects safely and quickly, while
allowing all the trays to maintain alignment, made possible by the
directive labeling and the non-skid under-surface of the tray. The
"V" shape formed from the higher, rear side towards the front lower
side also helps in opening and sliding through the lead curtains of
the X-ray machine. Another, quite useful feature of the tray is
that it is stackable up to groups of 20, making for easier storage
and transportation. The tray also has another very positive feature
in that it carries a metal step wedge, which allows the X-ray
machine to check its own performance. The inventor, who has had a
life time of experience with such security systems, feels that all
the features previously sited can be provided in a single tray,
offering an advance in the art of security, based on a faster and
better 24-hour vigilant response.
PRIOR ART
[0002] Researching prior art regarding this invention, showed
similar concepts were patented in.

[0006] However, none were separable plastic trays and none were
used in relation to X-ray machines. They were part of a more
complex piece of equipment or made to go through a wall.

Office on Aug. 2, 2001 and recorded as # 497968, Steven Craig
Holland personally claims all patenting and comunercial rights to
this invention.
INVENTION SUMMARY
[0008] A brief description of the invention is as follows. A light,
easy to handle, translucent, plastic tray used for transactions
through an X-ray machine, allowing easier handling and affording
better X-ray wall penetration. This invention, therefore, makes for
safer inspections, allowing the tray to be handled with one hand,
yet making the tray spacious enough to hold all pocket objects.
With a non-skid pad on the underside, the tray travels the belt,
less susceptible to moving around inside the X-ray machine,
allowing safer and more reliable transport of its contents. Yet,
this invention remains a low cost item, due to the type of material
and the vacuuming process used to produce it.

DESCRIPTION
[0018] The security tray is seen in perspective on FIG. 1, showing
all the details of the tray looking from the inside and two outer
sides. A base 1, enclosed by four sides, tapered outward in
relation to the base. All areas of the tray are integrally formed
from one common sheet of translucent plastic and trimmed. The front
side 2 is lower than the rear side 3. Both the right 4 and left 5
sides are equal and have a trapezoidal shape, giving the tray a
tapered shape from front to back, allowing the tray to easily open
the two halves of each of the X-ray machine's lead curtains. The
base 1 has several hot-formed bosses rising from its inside
surface: in the front, it has three (3) arrows 6, 7, and 8, painted
in bright yellow. Above the arrows, widthwise, is a centered
rectangle with raised edges 9, framing an area where a directional
instruction label 1d is bonded. Located above, on the left side of
the frame 10 is a smaller raised pad 11, allowing the bonding of an
X-ray metallic, stepped wedge to be used as a test piece 12. The
metal, stepped wedge is bonded on the base of each tray to allow
verification of the machine's performance for QC. This wedge allows
the system to detect any defect of the X-ray calibration, allowing
the system to stop by detecting any abnormal x-ray signals. Further
up the tray, centrally located between the base 1 and the bottom of
the rear wall 3, is a 90.degree. arc with an external opening 13,
allowing placement of four fingers. The holder can now pinch the
tray by placing the thumb of the same hand on the top rear edge of
the tray and applying pressure (see rear view, FIG. 6). Each of the
front 2 and rear 3 sides have two blind ears, 14 and 15 on rear
side 3 and 16 and 17 on the wall of the front side 2. These ears
are used as stops when several trays are stacked within each other
(see FIG. 3). FIGS. 4, 5, 6 and 7 show four orthographic views of
the tray. These figures show the left, top, rear and bottom sides
of the tray in different views. The bottom of the tray has a
non-skid plastic pad 25, allowing better stability while traveling
the belt through the X-ray machine during inspection (see FIG. 8).
A metal, stepped wedge 12 is bonded onto the pad 1l. This wedge
allows the X-ray projection system to be verified for reliability
with every tray excursion through the machine. The operator can now
more easily notice any breakage or lamp defect as well as the
X-ray's dynamic intensity with more regularity than is presently
available. This technique consists of a flow of "X" rays, see FIG.
8, emitted from an X-ray metallically-sealed electronic lamp 18,
where an electric current flows through a cathode 19, causing it to
become extremely hot. The heat releases electrons from the cathode,
while at the same time, a high voltage is applied across the
cathode and the anode 20. This voltage forces the electrons to
travel at high speed toward a slanted tungsten target. X-rays are
then produced when the electrons strike the angularly reflective
target. They form a frustum of pyramid 21 penetrating and crossing
through the metal envelope 22 which is trimmed by an aperture 23,
allowing an array large enough to cover the width of the transfer
belt 24. The X-ray bundle then passes through the belt 24 and
impacts a receiving screen 25, which transmits the reception to a
CRT screen ( not shown) placed at a convenient reading area for
visual inspection. As the tray 1 moves along the belt with its
contents, the X-ray profiles all objects, with the metal wedge
giving several signals of different intensity on the several, thin
steps and none on the last thick one. This modulation verifies that
the x-ray bundle's intensity is correct at each phase,
automatically alerting the machine to any system change.
