Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a tool box tray structure,
and more particularly to a tool box tray structure made of
different colors of PET plates which are worked by a secondary heat
press process to form the tool box tray structure having different
colors, thereby facilitating the user identifying the kinds of the
hand tools by the color contrast.
[0003] 2. Description of the Related Art
[0004] A conventional tool box comprises a main body consisting of
a top cover and a bottom cover, and a tool box tray mounted on the
main body and located between the top cover and the bottom cover
for storing hand tools of different types. However, the tool box
tray only has a single color, so that the user cannot identify the
size and type of the hand tool by the color of the tool box tray,
thereby causing inconvenience to the user in identification.
SUMMARY OF THE INVENTION
[0005] The primary objective of the present invention is to provide
a tool box tray structure that has a double-color molded recess
having a first color provided by the one-color tray and a second
color provided by the PET plate.
[0006] Another objective of the present invention is to provide a
tool box tray structure, wherein the PET plate is bonded on the
first receiving recesses and the second receiving recesses of the
molded recess, and the size indication zones of the molded recess
is formed by the one-color tray so as to provide a color contrast,
thereby facilitating the user identifying the kinds of the hand
tools by the color contrast of the one-color tray and the PET plate
having different colors.
[0007] A further objective of the present invention is to provide a
tool box tray structure, wherein the tool box tray structure is
made of the PET material having a greater tensile strength and a
greater bending strength to enhance the strength of the molded
recess, so that the tool box tray structure can be used to support
heavier hand tools.
[0008] A further objective of the present invention is to provide a
tool box tray structure, wherein each of the size indication zones
of the molded recess is provided with a size indication mark, so
that the user can identify the size of the hand tool by the color
of each of the size indication zones of the molded recess and by
the size indication mark of the respective size indication
zone.
[0009] In accordance with the present invention, there is provided
a tool box tray structure, comprising:
[0010] a molded recess for mounting hand tools of different
types;
[0011] the molded recess including a first layer having a first
color and a second layer having a second color bonded on the first
layer.
[0012] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0026] Referring to the drawings and initially to FIGS. 5 and 6, a
tool box in accordance with the preferred embodiment of the present
invention comprises a main body 1, and a tool box tray structure 10
mounted on the main body 1. The tool box tray structure 10 is
formed with a double-color molded recess 3 for mounting hand tools
of different types.
[0027] The molded recess 3 includes a plurality of first receiving
recesses 31 each having the shape of a screwdriver handle for
receiving a screwdriver handle 40, a plurality of second receiving
recesses 32 each having the shape of a screwdriver shank for
receiving a screwdriver shank 41, and a plurality of size
indication zones 33 for indicating the size of the screwdriver
shank 41.
[0028] The tool box tray structure 10 is preferably made of PET
(polyethylene terephthalate) material having a greater tensile
strength (500 kgf/cm.sup.2) and a greater bending strength (700
kgf/cm.sup.2). In addition, the tool box tray structure 10 is
formed by a heat press process.
[0029] Referring to FIGS. 1-4 with reference to FIGS. 5 and 6, the
tool box tray structure 10 is manufactured by the following
methods.
[0030] First of all, a first PET plate 20 is placed into a first
forming mold 30. The first forming mold 30 is formed with the
molded recess 3 including a plurality of first receiving recesses
31 each having a size slightly greater than that of the screwdriver
handle 40, a plurality of second receiving recesses 32 each having
a size slightly greater than that of the screwdriver shank 41, and
a plurality of size indication zones 33 for indicating the size of
the screwdriver shank 41. Then, the first forming mold 30 is closed
and heated to a predetermined temperature, so that the first PET
plate 20 placed in the first forming mold 30 is softened and is
bonded in the molded recess 3 of the first forming mold 30 as shown
in FIG. 1, thereby forming a one-color tray 11 (see FIG. 2). Then,
the one-color tray 11 is cooled and removed from the molded recess
3 of the first forming mold 30.
[0031] Then, the one-color tray 11 is placed into a second forming
mold 50 having the same form as that of the one-color tray 11 as
shown in FIG. 2. Then, a second PET plate 21 is placed into the
second forming mold 50 and is rested on the one-color tray 11. The
second PET plate 21 has a color different from that of the
one-color tray 11. Then, the second forming mold 50 is closed and
heated to a predetermined temperature as shown in FIG. 3, so that
the second PET plate 21 placed in the second forming mold 50 is
softened and is bonded in the molded recess 3 of the one-color tray
11 as shown in FIGS. 3 and 4, thereby forming a double-color tool
box tray structure 10 as shown in FIG. 4. Then, the double-color
tool box tray structure 10 is cooled and removed from the second
forming mold 50.
[0032] In such a manner, as shown in FIGS. 4-6, the tool box tray
structure 10 includes a one-color tray 11, and a PET plate 21
mounted on the one-color tray 11 and having a color different from
that of the one-color tray 11. Thus, the tool box tray structure 10
has a double-color molded recess 3 having a first color provided by
the one-color tray 11 and a second color provided by the PET plate
21. Preferably, the PET plate 21 is bonded on the first receiving
recesses 31 and the second receiving recesses 32 of the molded
recess 3, and the size indication zones 33 of the molded recess 3
is formed by the one-color tray 11 so as to provide a color
contrast, thereby facilitating the user identifying the kinds of
the hand tools by the color contrast of the one-color tray 11 and
the PET plate 21 having different colors.
[0033] In addition, the tool box tray structure 10 is made of the
PET material having a greater tensile strength and a greater
bending strength to enhance the strength of the molded recess 3, so
that the tool box tray structure 10 can be used to support heavier
hand tools.
[0034] Further, each of the size indication zones 33 of the molded
recess 3 is provided with a size indication mark 34 (see FIG. 6A),
so that the user can identify the size of the hand tool by the
color of each of the size indication zones 33 of the molded recess
3 and by the size indication mark 34 of the respective size
indication zone 33.
[0035] Referring to FIGS. 7-12, a tool box tray structure 10A in
accordance with another embodiment of the present invention is
shown, wherein the construction of the tool box tray structure 10A
is substantially similar to that of the tool box tray structure 10,
and the difference therebetween is described as follows.
[0036] As shown in FIG. 7, the first PET plate 20A has a plurality
of hollow portions to mate with the molded recess 3, so that after
the one-color tray 11A is formed, the molded recess 3 of the
one-color tray 11A has a hollow bottom as shown in FIG. 9. Then,
the one-color tray 11A is placed into the second forming mold 50
having the same form as that of the one-color tray 11 as shown in
FIG. 9. Then, the second PET plate 21 is placed into the second
forming mold 50 and is rested on the one-color tray 11A. Then, the
second forming mold 50 is closed and heated to a predetermined
temperature as shown in FIG. 10, so that the second PET plate 21
placed in the second forming mold 50 is softened and is bonded in
the molded recess 3 of the one-color tray 11A as shown in FIG. 10,
thereby forming a double-color tool box tray structure 10A as shown
in FIGS. 11 and 12. Then, the double-color tool box tray structure
10A is cooled and removed from the second forming mold 50.
[0037] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
