Description
BACKGROUND OF THE INVENTION
In the packaging of various products (e.g. hardware) it is
oftentimes important from a sales standpoint that the product
itself be exposed to the view of the customer without requiring
that the product be removed from its container. While substantial
product exposure is important, it is also equally important that
the container for the product be of simple construction, provide
adequate protection for the product during shipment or storage
thereof, and that the package be tamper-proof.
Various prior packages have heretofore been provided; however,
because of certain design characteristics they have been incapable
or ineffective in meeting all of the requisites afore-enumerated.
Furthermore, many of the prior packages were awkward and difficult
to assemble, and the material costs of the various components
therefor were inordinately high. In other instances the package was
unattractive and was not versatile in accommodating a variety of
products.
SUMMARY OF THE INVENTION
Thus, it is an object of this invention to provide a package which
avoids the shortcomings aforenoted associated with prior packages
of this general type.
It is a further object of this invention to provide a package
wherein certain components thereof might assume a collapsed state,
when desired, thereby reducing the required storage space for the
package.
It is a still further object of this invention to provide a package
wherein various components thereof may be formed from blanks cut
and scored on conventional equipment.
Further and additional objects will appear from the description,
accompanying drawings, and appended claims.
In accordance with one embodiment of this invention a package is
provided which includes a collapsible sleeve member on a portion of
which a product is mounted and supported thereby. The sleeve member
includes end portions separated by a central portion having a top
recessed with respect to the tops of the end portions and on which
the product is mounted; a bottom; and walls interconnecting the top
and bottom. One of the walls of the central portion is of sectional
construction and has one section thereof projecting above the
central portion top an amount greater than the amount the
accommodated product projects above the said top. A second section
of the sectional wall is foldably connected to the one section and
is disposed in face-to-face relation therewith.
Positioned within the end portion of the sleeve member and
frictionally retained therein is a receptacle. The receptacle may
be removed endwise, when desired, from the end portion of the
sleeve member. The receptacle, when disposed within the end portion
of the sleeve member, serves to retain the latter in a
non-collapsed state.

Referring now to the drawings and more particularly to FIG. 5, a
preferred form of the improved package 20 is shown. Package 20
comprises an elongated sleeve member 21, a receptacle 22 secured to
one end of the member 21, and a spacer piece 23 secured at the
opposite end of the sleeve member. The sleeve member 21, the
receptacle 22, and the spacer piece 23 are formed, respectively,
from blanks 24 (FIG. 1), 25 (FIG. 2), and 26 (FIG.- 3). In certain
variations of the improved package, to be hereinafter described,
the receptacle and/or spacer piece may be omitted.
The blanks 24-26 are preferably formed from double-faced corrugated
or solid fiberboard and are cut and scored on conventional high
speed equipment, the function and operation of which are well known
in the container field.
Blank 24, as illustrated, has a substantially rectangular
configuration and is provided with a set of spaced substantially
parallel first foldlines 27, 28, 30, and 31. Each first foldline,
with the exception of foldline 28, extends substantially the full
length L of the blank 24. The foldlines cooperate with the side
edges of the blank to form a pair of outer panels I and II, a pair
of inner panels III and IV, and a manufacturer's glue panel V.
Panel III, as seen in FIG. 1, is provided with a pair of elongated
transversely extending cuts 32 and 33 which are disposed in
substantially parallel relation. Each cut is spaced inwardly from
the edge of the blank and spans the entire width of the panel.
Interconnecting the cuts 32 and 33 is an elongated second foldline
34 which is in spaced, substantially parallel relation with respect
to first foldline 27. Cuts 32 and 33 and foldlines 27, 28, and 34
cooperate with one another to form an inner wall panel section 35
and a top portion 36, all of which comprise a part of the central
portion C of the sleeve member 21. The central portion will be
described more fully hereinafter.
Panel III is also provided with a set of third foldlines 37 and 38
which extend from the cuts to the adjacent edge of the blank. All
of the foldlines 27-31, 34, 37 and 38 are disposed in parallel
relation and extend lengthwise of the blank. Foldlines 27, 28 and
37 and cut 32 cooperate with one another and the adjacent edge of
the blank to form a top portion 39 and a segment 40 of a side wall
41. The top portion 39 and side wall segment 40 form a part of an
end portion A of the sleeve member 21, see FIG. 5.
Foldlines 27, 28, and 38 and cut 33 in a similar fashion cooperate
to form a top portion 42 and a segment 43 of the side wall 41 which
coact to form the other end portion B of the sleeve member 21.
As will be noted in FIG. 1, the top portion 36 of the central
portion C of the sleeve member 21 is provided with a plurality of
apertures 44a, 44b, and 44c. The number, size, shape, and location
of the apertures will depend upon the type of product P being
packaged.
Panel I forms a side wall 45 of the sleeve member when the latter
is set up. The portion 45a of the side wall adjacent the foldline
27 forms an outer wall panel section in substantially coextensive
relation with wall panel section 35; said sections cooperate to
form a multi-ply wall W which projects upwardly from the side of
the central portion top 36 when the blank is set up to form the
sleeve member, see FIG. 5.
Panel II is adapted to form the bottom 46 of the sleeve member 21
when it is set up. The opposite end segments 46a and b of panel II
form the bottoms, respectively, of the sleeve end portions A and B.
Panel II is also provided with openings 47a, b, and c which are
aligned with corresponding openings 44a, b, and c when the sleeve
member 21 assumes a collapsed state, as seen in FIG. 4. The
openings 47a, b, and c are adapted to accommodate any parts of the
product P which project downwardly from the underside of the top 36
of the central section C, when the sleeve member is in a collapsed
state, see FIG. 4, thereby permitting greater compactness of the
collapsed sleeve member.
In addition to openings 46a-c, bottom end portion 46b may be
provided with a slot or slit 48 which is adapted to receive a tab
50 formed along the bottom edge of spacer piece 23 when the latter
is mounted within the end portion B of the sleeve member 21. When
no spacer piece is being used, or where the spacer piece is fixedly
secured by adhesive or the like to the sleeve member end portion B,
the slot 48 may be omitted.
Panel V is a conventional manufacturer's glue flap 51, which is
secured by adhesive or staples to the interior surface of side wall
45, when the blank 24 is set up to form sleeve member 21. Where
tape or the like is used in setting up the blank 24, the flap 51
may be omitted. As noted in the set-up embodiment shown in FIG. 5,
the top surfaces of the end portions A and B and the upper edge of
the multi-ply wall W are disposed in coplanar relation. The top
panel of the central portion C on which the product P is supported
is recessed from the top surfaces of the end portions so that the
accommodated product will not protrude above the top surface of the
end portions A and B, see FIG. 6. In a like manner the front side
wall of the central portion C and the front side walls of the end
portions A and B are in coplanar relation. The outer wall panel
section of the rear side wall of the central portion C and the rear
side walls of the end portions A and B are also disposed in
coplanar relation.
Blank 25 is of conventional design used in forming a receptacle 22
having a hinged cover panel 52, see FIG. 7. The height, width, and
depth of the receptacle will be determined by the shape of the end
portion A of the sleeve member 21. The receptacle is adapted to
accommodate various parts (e.g., screws, nuts, etc.) used in
connection with the product P subsequent to its being removed from
the package. If, for example, the packaged product is a decorative
door lock, the parts accommodated in the receptacle 22 might be the
tumbler and associated parts, and decorative escutcheons and
accessories utilized in mounting the lock on one side of the door.
Thus, with the improved package, the customer might select a lock
wherein the parts thereof exposed on one side of the door might be
of one style and the parts thereof exposed on the other side of the
door might be of the same or a different style. Thus, in such a
situation, the improved package is highly versatile from a
merchandising standpoint in that various combinations of decorative
styles can be achieved by the customer by merely interchanging the
receptacle 22 with some other receptacle.
The receptacle is slipped endwise into the end portion A and is
held therein by friction, and/or complemental locking components,
such as locking lugs, tabs, or the like.
In FIG. 8a, the receptacle 22 is shown retained in the end portion
A of a slightly modified sleeve member 21' by a foldable tab T
which may be formed on the edge of end portion 46b of bottom panel
46 of the sleeve member. The tab T, when folded, overlies an
exposed wall panel of the receptacle 22 and has a locking tongue or
first lock component T' inserted within a suitable slot or second
lock component S, which may be formed in the wall panel of the
receptacle.
Besides cover panel 52, blank 25 includes wall panels 53, 54, 55,
and 56, a manufacturer's glue flap 57, and tuck flaps 58 and 60
secured to the upper edges of panels 54 and 56, respectively. The
configuration and arrangement of the bottom closure flaps are of
conventional design. The shape and size of blank 25 may vary from
that shown without departing from the scope of the invention.
Blank 26 for the spacer piece 23 includes a central foldline 65
which interconnects panels 66 and 67. When the blank 26 is set up,
panels 66 and 67 assume a face-to-face relation and close-off the
end portion B of the sleeve member 21, see FIG. 5. The locking tab
50, as afore-identified, is formed along the bottom edge of panel
66. Each panel 66 and 67 has a pair of narrow side panels 66a-b,
and 67a-b, which are folded at right angles to the respective
panels 66 and 67 and resiliently and frictionally engage the
interior surfaces of the vertical walls 43 and 45 of the sleeve
member, when the spacer piece is positioned within the end portion
B. The spacer piece 23 and the receptacle 22, when assembled with
the sleeve member 21, firmly retain the latter in a set up or
non-collapsed state. In addition, the spacer piece and receptacle
reinforce the ends of the sleeve member.
FIG. 11 shows a second modified form 120 of the improved package.
Parts of package 120 which are similar to or the same as the
corresponding parts of package 20 will be given a corresponding
number, except in the 100 series. The principal structural
difference between packages 20 and 120 is that in the latter,
closure flaps 170a, b, and c have been provided which are foldably
connected to the end portion A of the sleeve member 121 and may be
substituted for the receptacle 22. Similar closure flaps 171a, b,
and c are also provided which are foldably connected to the other
end portion B of the sleeve member 121 and are substituted for the
spacer piece 23. Once the flaps at the end portions A and B have
been folded into end-closing positions, the sleeve member 121 will
be retained in a set up or non-collapsed condition.
The blank 124 for forming the package 120 is shown in FIG. 10, and
may be readily set up either manually or by automatic or
semi-automatic equipment.
FIG. 13 shows a third modified form of improved package 220. As in
the case of package 120, parts of package 220, which correspond to
parts of package 20 or 120, will be identified by similar numbers,
except in a 200 series.
Package 220 has a central portion C of the sleeve member which
includes a recessed top separated into sections 201 and 202 by a
vertically projecting, longitudinally extending partition 203.
Partition 203 is formed by a pair of elongated panel sections 203a
and 203b which are joined together by an elongated foldline 204.
Each section 201 or 202 is adapted to supportingly engage a
separate product, not shown. The height of the partition 203 with
respect to the plane of top sections 201 and 202 is greater than
the extent to which the accommodated product protrudes upwardly
from the top section 201 or 202.
A side wall 241 of substantially the same configuration is disposed
on opposite sides of the sleeve member. Portion 243 of each side
wall 241 defines in part the end portion B of the sleeve member 221
and portion 240 of the same side wall defines in part the end
portion A, see FIG. 13.
The bottom of the sleeve member 221 is formed by a pair of
interlocking sections 205 and 206. Section 205 is connected by a
foldline 207 to one of the side walls 241. Section 206 is connected
to the other side wall 241 by a similar elongated foldline 208, see
FIG. 12. Section 205 in the illustrated embodiment is provided with
a pair of locking tabs 210 which are adapted to lockingly engage
suitable slits 211 formed in a foldline 212, the latter
interconnecting section 206 with an elongated complemental section
206a. Other means (e.g., adhesive, staples, etc.) of
interconnecting sections 205 and 206 so as to form the bottom of
the sleeve member may be utilized from that shown without departing
from the scope of the invention.
Cuts 213 and 214 are provided in the blank 224 which delimit end
portion A from central portion C and end portion B from the central
portion. Each cut is of like configuration and comprises a linear
first segment 213a or 214a and a non-rectilinear second segment
213b or 214b. Each second segment has an angularly offset inner end
213c or 214c which terminates at foldline 204, see FIG. 12, and is
spaced from the inner end of segment 213a or 214a which also
terminates at foldline 204. By reason of the offsetting of the
inner end 213c or 214c, a reinforcing gusset 215 is formed at each
end of the partition 203.
FIGS. 14-17 disclose a modified spacer piece 323 and blank 324
therefor. Piece 323 may be substituted for piece 23 shown in FIG. 5
in exploded relation with one end B of the sleeve member 21. The
blank 324, see FIG. 14, may be formed of double-faced corrugated
fiberboard or the like, and includes a back panel 325 having an
inner end panel 326 connected by foldline 327 to one edge of panel
325. The foldline 327 is interrupted by a struckout 328, the
function of the latter will be discussed more fully
hereinafter.
To the opposite edge of panel 325 is foldably connected an end
panel 330, which, in turn, forms a part of a nose section N, the
latter being formed when the blank 324 is set up to form the spacer
piece 323, see FIGS. 15-17.
Panel 330 is provided with an elongated slot 331, which extends
transversely of the foldline connecting panels 325 and 330. The
size of slot 331 is such that it will slidably accommodate the
thickness of the panel 36, comprising a part of the sleeve member
21, when the sleeve member and spacer piece 323 are in assembled
relation.
Connected by foldline 332 to panel 330 is a triangularly shaped
piece 333, which forms a section of the nose N when the blank 324
is set up, see FIGS. 15 and 16. A second side of piece 333 is
connected by foldline 334 to one edge of a front panel 335. The
remaining third side of triangular piece 333 is separated from
panel 335 by a cut 336. Thus, when the blank 324 is set up, the
nose N will project forwardly from front panel 335, see FIGS.
16-18.
To the edge of panel 335, which is opposite piece 333, is foldably
connected an outer end panel 337. Panel 337 is provided with a
tongue 338 which is adapted to interlockingly engage in a
conventional manner, a slot formed by the struckout 328, when the
blank is set up to form the spacer piece 323.
Once the spacer piece 323 has been formed, it is moved endwise into
the end B of sleeve member 21, thereby closing the end of the
sleeve member and providing reinforcement therefor. The nose N of
the spacer piece 323 enhances the appearance of the package while
at the same time provides added protection for the accommodated
product by strengthening the sleeve member.
In all of the illustrated embodiments of the improved package, the
product is preferably retained on the top surface of the sleeve
central portion by a thin pliable, heat-shrink plastic film F, see
FIG. 6, which snugly encompasses the upwardly projecting portions
of the product and is bonded by adhesive or heat sealing to the
exposed surface of the top and side walls of the central portion.
The method utilized in applying the film to the product and
surrounding surfaces of the sleeve member may be one commonly
referred to in the packaging industry as "skin-pack." Other means
of securing the product to the sleeve member may be obviously
utilized, if desired.
Thus, it will be seen that a simple, sturdy, and attractive package
has been provided which may be readily set up and assembled either
manually or by automatic high speed equipment. The package is
versatile in accommodating a variety of products.
