Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to packaging and
more particularly to packaging for storing, supporting and shipping
flexible drywall trim devices.
[0003] 2. General Background and State of the Art
[0004] The design and construction of packaging to receive and
support odd shaped objects have long been a challenge. Corrugated
cardboard has been a popular lightweight and inexpensive sheet
material for the constructing of different packaging.
[0005] The finishing of corners and seams between drywall panels
has long posed a problem. Elongated corner beads have long been
used to finish such corners. Such beads typically consist of a
length corresponding with the overall height of drywall panel walls
and having a cross-sectional configuration corresponding with the
configuration of the joint to be finished, such as a square corner,
or corners having joining angles of different configurations. It
has been common practice to stack such beads together in a
rectangular-in-cross-section elongated corrugated cardboard package
for shipping to the construction finishing site. The packages,
however, are often subjected to rough handling during shipping,
causing the flanges of the corner beads to be flexed or twisted,
frequently beyond the yield point, resulting in irregularities or
bends in the beads which can lead to rejection or time consuming
straightening techniques during the installation process. The
situation is exacerbated for tape-on style beads and trim which
incorporate paper wings or flaps projecting beyond the edges of
metal cores and particularly susceptible to being flexed and bent.
In any event, the efficiency of installation demands that the
configuration of such fittings maintained throughout storage and
shipping and that the product be delivered to the work site without
twists or warping throughout their length.
[0006] Containers of various configurations have been proposed for
packaging elongated strips. Containers have even been proposed to
be wrapped about a collection of elongated strips for the purpose
of allowing for flexing thereof. A device of this type is shown in
U.S. Pat. No. 2,340,422 to Okonski. Containers of this type are not
intended to support drywall strips against flexing and bending
during storage and shipment.
[0007] There, thus is a need for a package configured to support
the packaged drywall beads and trim against bending or
twisting.
INVENTION SUMMARY
[0008] The elongated package of the present invention is
constructed of a sheet folded along fold lines to form first and
second sidewalls. The sheet projects beyond the bottom extent of
one of the sidewalls and turns inwardly toward the other and is
configured with a raised support rib defining the cross-sectional
configuration of a drywall strip support such strip. In the
preferred embodiment, such rib supports a drywall finish strip
having a generally orthogonal cross-sectional configuration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Referring to FIGS. 1-3, the package of the present invention
is fabricated from a flat sheet 21 and may be folded along fold
lines to form, generally, a top wall 23, sidewalls 25 and 27 and an
extension from the sidewall 25 which forms a rib device 29 and 31
rising upwardly in the interior of the package as viewed in FIG.
3.
[0021] In the construction industry, the finishing of joints, such
as corner joints between drywall panels to a pleasing appearance
can be relatively time consuming. This problem led to the
development of finishing trim such as corner beads which include a
pair of angular flanges for laying down over the marginal edges of
joining drywall panels and which may themselves be formed of, or
covered with, fibrous material, such as paper having a texture and
surface similar to that of paper covering the drywall panels. A
device of this type is disclosed in U.S. Patent Application Pub.
No. 2003/0033770 A1 assigned to the assignee of the instant
application.
[0022] Corner beads of this type are typically on the order of 9
feet long. Care is taken during manufacture to form angular flanges
in a flat plane. This is intended to allow the craftsman on the
construction site to withdraw such beads from the packaging in
which they are packaged and apply the flanges of beads to the
planer panels forming corner or other joint being covered.
Typically, a joint compound or other material is applied to the
joint to adhere the trim piece in place to form a straight-line
attractive joint covering. Drywall workers involved in the
finishing process are relatively skilled and enjoy a relatively
high pay scale either on piecework or an hourly wage. Thus, it is
important for the success of a construction project that the
finishing process take place in a relatively efficient manner.
Furthermore, since the quantity of corner bead trim material
supplied to the job site is coordinated in accordance with the
lineal feed of joint to be covered, it is advantageous there be
minimal rejection of the bead material on site so that the quantity
of material required corresponds with the quantity scheduled for
the particular job site. To this end, it is important that the
quality and configuration of the corner bead is maintained during
the package, shipping and handling of the product prior to the
installation step.
[0023] It has been common practice to package a number of such
corner beads together in a rectangular in cross-section cardboard
packaging for storage and shipping to the job site. Unfortunately,
such packaging typically fails to incorporate any effective means
for supporting and maintaining the corner beads in the desired
configuration thus often resulting in bending or cracking the
flanges of such beads during shipment and handling, even to the
extent that the flanges are sometimes bent beyond the yield point
resulting in them taking a permanent set either in angular
orientation relative to one another or in assuming longitudinal
configuration which is non linear thereby failing to match the
linear configuration of a drywall panel on which the flange or
flanges are to be mounted. This is the problem to which the package
of the present invention is directed.
[0024] One preferred embodiment of the package of the present
invention is constructed from a sheet 21 made of corrugated
cardboard. Referring to FIGS. 1 and 3, for corner beads or other
drywall trim having designed to be installed on joints formed
between drywall panel used in residential or office construction
having 9 foot ceilings, the sheet will be cut to a length of 9 feet
and may typically have a width of about 11/2 feet to be, when
folded along respective creased fold lines 35-49, form return panel
51, first and second rib panels 53 and 55, bottom wall 29, first
sidewall 25, top wall panels 57 and 59, second sidewall panel 27
and the closure flap 61. A plurality of staples 63 are stapled
through the flap 61 bottom wall 29 and the return 51 to secure the
package in its erected position.
[0025] The sheet 21 itself may be constructed of numerous different
materials, such as solid cardboard, fiber board, corrugated
cardboard, plastic or any other structural sheet having sufficient
rigidity to provide structural support and of a sufficiently light
weight character as to provide practical packaging function. By
sufficiently rigid I mean the sheet, while having flexibility, will
be sufficiently rigid in the unweakened areas away from the fold
lines to, when erected and stapled (FIG. 3), to resist crushing or
bending during normal handling associated with loading and
unloading from transport trailers and to withstand stacking of a
number of erected packages in warehouses and storage sheds.
[0026] As viewed in FIG. 1, the sheet 21 may be creased or
perforated during the manufacturing process to form the respective
fold lines 35-49 defining hinges for convenience of folding
thereof. When the package is to be formed and assembled, the
workman may fold the sheet along the fold lines 35, 37 and 39 to
form the turn back panel 51 at the bottom of the triangularly
shaped rib device 31 and to form the upwardly and convergently
angled rib panels 53 and 55 (FIG. 3). Further folding along the
crease lines 41, 43, 47 and 49 will form the sidewalls 25, angular
top panels 57 and 59, sidewall 27 and closure flap 61.
[0027] In the embodiment shown, the package is intended to receive
drywall beads, generally designated 71 (FIG. 9) for packaging and
transportation thereof. The drywall beads 71 are of the type
sometimes referred to as tape-on beads and include, as an example,
respective angular metal cores 73 (FIG. 11) which include flanges
bent transversely at an angle of slightly less and than 90.degree.
to one another to, in use, fit tightly over the right angle corner
of a joint between drywall panels. The cores 73 are covered by a
paper 75 that projects laterally beyond the opposite edges of such
core to form flexible paper wings 77 which are intended to, in
practice, overlie the marginal edges of the wallboard being
covered. It is a problem with these so called paper beads 71 that,
when packaged in conventional packages for shipping, the cores
and/or wings roll or twist during handling and maneuvering of the
packaging thus causing the paper wings, and sometimes the cores
themselves to become twisted or bent out of the plane of the body
of the respective wings or core flanges such that they do not mate
well against the flat surface of the drywall panels. It is the
problem associated with this rolling and bending to which the
present invention is addressed.
[0028] A typical drywall corner bead might have angular metal
flanges having a width of about 1{fraction (1/4)} inches with the
paper wings extending {fraction (3/4)} of an inch to and an inch
beyond the distal edges thereof to cooperate with the respective
core flanges to form a lateral span extending of about 2 to
2{fraction (1/4)} inches from the corner of the bead. The width of
the respective rib panels 53 and 55 is such as to provide support
for the entire core flange and paper wing on each side of the
respective beads to resist rolling and bending of the entire flange
and wing. In the preferred embodiment such panels have a width of
about 21/4 inches to provide full lateral support for beads having
a flange and wing span of 2 to 21/8 inches.
[0029] As will be apparent to those skilled in the art, the package
of the present invention can be constructed to support drywall trim
having many different cross-sectional configurations, as for
example, bull-nose drywall trim or beads with a core with a rounded
transverse cross-section and lateral flanges projecting at various
angles varying from about 90.degree. to one another up to
120.degree. as with the right angle beads the flanges are covered
with paper, which projects beyond the metal flanges to define paper
wings. The shape of the support rib and span of the panels 53 and
55 will be configured to compliment the transverse shape of the
bead a trim strip being packaged.
[0030] For the preferred embodiment, the rib panels 53 and 55
project orthogonal to one another at substantially 90.degree. to
one another such that in the flanges 75 of the respective core 73
are nested there against, those flanges, angling relative to one
another at an angle slightly less than 90.degree., are thus, when
nested on the rib device 31, biased outwardly slightly away from
one another to thus form a nested firm fit unto the support rib 31
itself.
[0031] The packaging of the present invention may be conveniently
fabricated from the sheets 21 with perforations or otherwise
diminished thickness to produce creases defining fold lines 35-49
and a supply of sheets in their flattened state may be stored in
stacked relationship ready to be erected to receive the drywall
beads to be packaged. When a supply of beads have been
manufactured, a quantity of sheets 21 may be withdrawn from the
storage stack and conveniently and rapidly folded along the crease
lines 35-49 as described above to form the cross-sectional
configuration shown in FIG. 3 and the staples 63 apply to staple
the panels in position. A quantity of drywall beads 71 may then be
inserted from one end or the other of the erected package to nest
in stacked relationship on the rib 31 as shown in FIG. 11 for
shipping. The ends of the package may be closed to capture the
beads in place or, as described below, inserted in a external
sleeve, generally designated 81 (FIG. 6).
[0032] The sleeve 81 is constructed from a flat sheet designated 83
(FIG. 5). In the preferred embodiment, the sheet 83 is made of
corrugated cardboard but, in practice, may be made of anyone of a
different number of sheet materials which provide sufficient body
to maintain the shape shown in FIG. 7 and to cooperate in providing
support for the package 23 inserted therein.
[0033] The sleeve 83 is formed with laterally spaced apart
longitudinally extending fold lines 85, 87, 89 and 91 dividing the
sheet into an internal flap 93 first sidewall 95 end wall 97 second
sidewall 99 and bottom wall 101. Such fold lines may take many
different forms, as for instance creases, diminished thickness of
the sheet along the lines, perforations or any one of a number of
forms well-known to those skilled in the art.
[0034] The sheet is stamped to be formed with flaps projecting from
the opposite end to form respective, opposite end sidewall flaps
103 and 105 and end wall flaps 107 and 109. The flap 105 is formed
with a pair of longitudinally spaced, transversely projecting fold
back full lines 111 and 113 and a transversely projecting fastener
slot 115 having one side thereof in alignment with a fold line 117,
and finally, a turn back fold line 119. The fold lines are spaced
longitudinally from one another to form, respectively, a first turn
back panel 121 closure panel 123 and second turn back panel
125.
[0035] The other side panel 95 is formed on its opposite ends with
longitudinally projecting closure flaps 127 having transversely
projecting turn back fold lines 129 and 131 disposed in closed
spaced relationship and a closure fold line 133 spaced there from
to cooperate in forming a return panel 135 and closure panel
137.
[0036] The end walls 97 and 101 are formed with respective
longitudinally projecting fold closure flaps 107 and 109, the flap
107 being formed at its base with close spaced transversely
projecting return closure fold lines 141 and 143. The flap 109 is
also formed in its base with close spaced return and closure fold
lines 145 and 147. The sheet 83 is stamped to form longitudinally
projecting clearance slots between the respective closure panels
103, 105, 107 and 109. The lateral outer side of the closure panel
109 is shaped to form at its base a longitudinally and inwardly
angled relief 151 to provide for narrowing of the flap 109 to
thereby provide clearance for folding into its assembled position
as to be described herein after.
[0037] As with the packaging described above, the sleeve sheets 83
may be cut to size, shape and creased to form perforations along
the fold lines 85-91 and the transverse fold lines described above,
as well as to punch out the closure slots 115. The flat sheets 83
may be stacked in storage at the manufacturing facility available
for erection when desired for the packaging process. As needed
sheets 83 may be withdrawn from the storage stack quickly folded
along the fold lines 85-91 to form the generally rectangular
construction shown in FIG. 7. Staples 181 will be inserted to
staple the panels 101 and 93 in overlying relationship.
[0038] One end of the sleeve may then be closed by folding in the
sidewall flap 105 along the fold lines 111 and 113 to recess the
panel the distance of the return section 121 leaving the slot 115
opening transversely inwardly as shown in FIG. 8 with the return
125 turning longitudinally outwardly to lay flush against the
opposite sidewall 95. The end wall flaps 107 and 109 are then
folded inwardly and, finally, the flap 139 folded longitudinally
inwardly along the fold lines 129 and 131 causing the return
segment 133 to lie along the wall 95 and the closure panel to bend
transversely inwardly so the fastening tongue 139 will be received
in the fastening slot 115 (FIG. 8).
[0039] The package 23 may then be inserted telescopically into the
open end of the sleeve 81 and such open end then closed by folding
the closure flaps 105, 107, 109 and 103 of such open end inwardly
as discussed here and above.
[0040] The entire package is then ready for shipping and the corner
beads 71 contained within the package 23 will be protected and
supported against unwanted rolling twisting. When the packaging
reaches the construction site, the workman can easily gain access
to the corner beads by withdrawing the fastener tongue 103 from the
slot 115 to withdraw the flap 103 and consecutively withdraw the
remaining flaps at one end of the sleeve to open the sleeve and
gain access to the corner beads packaged within the package 23.
[0041] From the foregoing, it will apparent that the package of the
present invention provides an economical and affective container
for receiving and supporting elongated angular objects, such as
drywall beads, against twisting, rolling and flexing during storage
and shipment such as to maintain the integrity thereof for
convenient and economic application thereof to drywall joints.
[0042] While the specification describes particular embodiments of
the present invention, those of ordinary skill can devise
variations of the present invention without departing from the
inventive concept
