Holder for flexible sided container
Abstract
A holder for a flexible sided container such as a box of facial
tissues comprises a pair of coactable base members each of which is
provided with container gripping means. The members are also
provided with adjusting means for controlling the separation of the
gripping means, the separation being directly related to the size
of the container. In most embodiments the gripping means will be a
pair of flanges which, when adjustment is proper, will deform the
flexible sides of the container to effectively hold the container
against displacement. The adjusting means permit sliding of one
base member relative to the other so that the separation of the
gripping means can be properly set.

Description
The present invention relates in general to holders for flexible
sided containers and in particular to holders for boxes of facial
tissues.
Boxes for facial tissues are commonly formed of light card stock
paper and are rectangular or square in shape. These boxes vary
considerably in the quantity of tissues contained within and in
their dimensions of length, width and height. One side of the box
is usually perforated so that a portion can be removed to permit
access to the tissues contained therein. Such boxes are normally
printed in attractive designs and colours so that they are pleasing
in appearance.
Existing tissue box holders come in many shapes and sizes but none
can be considered to be an optimum design. Some holders completely
envelope the tissue box like a second skin and thus hide the
aesthetic appearance of current boxes. Such holders do not
accommodate larger sized boxes at all and they can only sloppily
accommodate smaller sized boxes. Some holders are designed to sit
only on a flat surface while others will only sit on the
transmission hump of an automobile. Also many tissue box holders
will not permit the box to be held in a horizontal orientation
while the holder itself is oriented vertically. If the tissues lie
vertically they will tend to sag and fold within the box as their
quantities dwindle. Holders which are more versatile than most are
bulky and not easily positionable in convenient locations in
automobiles, boats, homes and offices.
The tissue box holders of the present invention overcome these
drawbacks since they are small, adjustable, inconspicuous, easily
mounted and they can be oriented either vertically or horizontally
while always holding the box horizontally. In its basic form the
present invention comprises a pair of coactable base members each
having container gripping means thereon. Means are provided on the
base members to adjust the separation of the gripping means and
maintain the members in the adjusted position. The separation of
the gripping means, which may be a pair of flanges directed towards
each other, is directly related to the size of the container to be
held. In operation the gripping means deform portions of opposite
sides of the container, trapping the connecting container panel
between the gripping means and the adjacent supporting surfaces of
the base members.
A number of configurations of the basic invention are possible, the
mechanism for adjustment being a main variable. For example,
mutually engageable ratchet teeth on the base members permit easy
reduction of the separation between gripping means for entrapment
of a box while inhibiting increased separation therebetween to
prevent removal of a box. Alternatively a plurality of interlocking
splines or ribs on the base members can be used to position the
gripping means in their predetermined positions. Any of the
adjusting means disclosed can be readily incorporated into the
basic design which lends itself to injection or compression
moulding. Each of the base members, with appropriate forethought,
can be moulded in a single step.
One additional advantage of the present invention is that the base
members may be readily provided with surface areas which accept
advertising copy. Thus the container holder of the present
invention could find use in disseminating information about, for
example, the product held thereby.

A preferred embodiment of the present invention is illustrated in
FIGS. 1 to 6. Flexible container holder 30 comprises tow coactable
main parts, namely a first base member 32 and a second base member
34. These members will be described individually from the
structural viewpoint and then their cooperative operation will be
defined.
First base member 32 comprises a generally rectangular base plate
portion 36 which has therein a congruent generally central and
rectangular opening 38. Wall means 40 are provided along the
opposite ends of the plate 36, the wall means extending away from
the plate surface a short distance. Wall means 42, similar and
parallel to wall means 40, are provided along opposite ends of
opening 38, extending away from the plate surface the same distance
as wall means 40. Extending along the outermost edge of each wall
means 40 and directed towards the adjacent wall means 42 is a
flange means 44, best seen in FIGS. 1, 2 and 4. Extending along the
outermost edge of each wall means 42 and directed towards the
adjacent wall means 40 is a flange means 46. Each pair of wall
means 40, 42 and flange means 44, 46 defines a guideway 48 which is
adapted to receive a portion of the second base member 34, as will
be described later.
Extending outwardly from plate 36 is abutment wall means 49, the
top surface of which is coplanar with the outermost edges of wall
means 40 and 42. In the preferred embodiment illustrated the
abutment wall 49 bridges the distance from one wall means 40 to the
other wall means 40 along one side of plate 36. The abutment wall
also is coextensive with the side of opening 38 adjacent the one
side of the plate and as such it merges with both wall means
42.
Extending outwardly from the top surface of the abutment wall 49 is
a side wall 50. As shown the side wall 50 runs the full length of
the abutment wall, but this need not be so as its main function is
to support the box gripping means 52. The box gripping means 52 is
illustrated as a flange directed inwardly of the plate and spaced a
short distance outwardly of the abutment wall top surface. The
flange 52 is substantially central of the abutment wall and is
provided with angled ends 54, the purpose of which will become
apparent during the discussion of the operation of the
invention.
On the side of the opening opposite abutment wall 49, the plate 36
is provided with a sloping portion 56, best viewed in FIGS. 2 and
5. Thus the thickness of plate 36 progressively decreases towards
opening 38 over approximately half the distance from the adjacent
outside edge of plate 36 to the adjacent inside edge of opening 38.
The purpose of this sloping portion will also become evident in
view of later discussions.
First base member 32 is provided with adjustment means in the form
of a pair of cantilevered ratchet plates 58 which are utilized in
adjusting the box holder of the present invention.
Each ratchet plate 58 is generally rectangular in plan and has one
longitudinal side thereof fixed to the inside surface of one of the
wall means 42 such that it overlies opening 38. The top surface of
each ratchet plate is coplanar with the top surfaces of the wall
means 40 and 42 and abutment wall 49. As shown in FIGS. 1 and 2
each plate 58 merges at one end thereof with the abutment wall but
this is not essential to operability of the invention. In fact the
invention would be operable if each ratchet plate 58 were only
cantelevered to an appropriate wall means 42 or to the abutment
wall 49.
The surface of each ratchet plate adjacent opening 38 is provided
with a plurality of transverse, parallel, tandemly oriented female
ratchet teeth 60. Each tooth has a generally saw tooth profile with
a ramp portion 61 and a locking portion 62 shown in FIGS. 5 and 6,
the teeth pointing towards abutment wall 49. Tooth 64 is at the
outermost end of the ratchet plate and has a height greater than
that of the remaining teeth by a distance 63. Its function will
also be described later.
Centrally located in each guideway 48 and adjacent the abutment
wall 49 is a mounting boss 65. The height of the boss 65 is the
same as that of the abutment wall and it is provided with a
countersunk portion 66 and a through hole 68. Mounting screws or
bolts can be located in the countersunk boss to fasten the first
base member to any supporting medium. Since the underside of plate
36 is also planar, double-sided adhesive tape can be bonded thereto
to facilitate ready mounting of the first base member to a
supporting surface, with or without the use of screws or bolts in
boss 65.
The second base member 34 will now be described in greater detail.
It essentially comprises a U-shaped base plate portion 70 which has
two legs 72 sized for reception in guideways 48. Each leg 72 has a
step 74 along the outermost edge thereof and a step 76 along the
innermost edge thereof, the height of the steps being equal to or
slightly less than the spacing from the top of plate 36 to the
underside of flanges 44 and 46 of the first base member. In order
to conserve material, each leg may be provided with a depression 78
in the bottom thereof, best seen in FIGS. 3 and 4.
Along the back of plate 70 runs abutment wall means 80 which, like
abutment wall means 49, need not extend the full width of the
member. The abutment wall 80 carries an inwardly directed box
gripping means 82, analagous to flange 52 and at the same height
above plate 70 as flange 52 is above plate 36. At this point it
should be pointed out that when the second base member is received
within the first base member the top surfaces of plates 36 and 70
are coplanar, as are flanges 52 and 82. As with flange 52, flange
82 is provided with angled ends 84.
Between the legs 72, spaced therefrom a distance 94 slightly
greater than the thickness of wall means 42 and projecting
outwardly from the cross-piece joining the legs is an adjusting
plate means in the form of a cantelevered ratchet plate 86, the
thickness of which is much less than the thickness of plate 70. The
outermost edge of ratchet plate 86 is coplanar with the outermost
ends of legs 70 and is provided with a pair of spaced apart male
ratchet teeth 88 sized for reception in female ratchet teeth 60.
These male teeth are best viewed in FIGS. 3, 5 and 6 and it is seen
that each tooth has a ramp surface 90 and a locking surface 92.
In the outermost end of each leg 72 is provided a cut-out 96 which
is sized to mate with the outer exposed surface of boss 65. Also,
centrally located on the ratchet plate 86 is a thumb release 98
which is in the form of a circular boss having a diameter less than
the spacing between ratchet plates 58 and a height no greater than
the top surface of plate 70. This boss has an inwardly sloping
annular surface 100 and exposes a circular portion of the ratchet
plate 86 at 102.
Both base members may have sloping side portions 104 and 106
extending the full length thereof, adapted to receive preprinted
advertising material or any such message.
Both base members lend themselves admirably to production by
injection or compression moulding techniques. In order to form the
various flanges integrally with the appropriate upstanding wall
means the mould dies may be designed with appropriate inserts which
would, when the part is withdrawn, leave a slot or cut-out
immediately below the associated flange. Thus cut-outs 108, 110,
112 and 114 appear immediately below flanges 52, 44, 46 and 82
respectively.
When assembling the two base members together, legs 72 with steps
74, 76 thereon are aligned with guideways 48 and the members are
forced together as shown in FIGS. 1, 4 and 5. Steps 74 first engage
in guideway 48 under flanges 44 and as the members slide together
steps 76 will engage under flanges 46 and ramp surfaces 90 of
ratchet teeth 88 will engage ramp surfaces 61 of ratchet teeth 64.
Continued sliding or drawing together of the base members will
force ratchet teeth 88 over ratchet teeth 64 and subsequently over
ratchet teeth 60 until movement is ceased. Withdrawal of the second
base member 34 from the first base member is prevented by the
locking action of surfaces 92 and 62 on teeth 88 and 60. However,
should it be desired to separate the base members, thumb guide 98
can be depressed and due to the flexible nature of cantilevered
plate 86 the teeth 88 will be forced out of engagement with the
teeth 60, thereby permitting sliding movement of the first base
member in the second base member between limits imposed by teeth 64
and abutment wall 49. If it is desired to remove the first base
member completely from the second base member, the thumb guide is
depressed and the first base member moved to where ratchet teeth 88
engage teeth 64. With the thumb guide depressed the first base
member may then be tilted upwardly at the back side thereof so that
ratchet plate 86 is tilted towards sloping surface 56. With the
first base member in this attitude engagement between ratchet teeth
88 and 64 is overcome and the first base member may be fully
withdrawn.
FIG. 5 illustrates the manner in which a flexible sided box may be
securely held by the present invention. A box, such as a tissue box
116, has flexible sides 118 and a bottom 120 which may be up to
three layers of card stock thick at the seam. A flange height of
3/16 of an inch should thus be allowed to clear the side wall
material in case a seam is present. With the first base member
extended so as to present the greatest opening between flanges 52
and 82 a box may be placed with its bottom 120 against the coplanar
top surfaces of plates 36 and 70 and one side against one of the
flanges 52 or 82. The two base members are then forced together so
that the other flange 82 or 52 engages the opposite side of the
box. The base members may then be drawn closer together by a
distance of at least one ratchet tooth whereby the flanges 52 and
82 compress the box therebetween by crimping and gripping the sides
118 at 122. Since the box bottom is strong relative to the sides,
the bottom will not tend to buckle and there is considerable
resistance to removal of the box in a direction perpendicular to
the plane of the holder. The box can, however, be removed easily in
one of two ways. It can be slid along the holder towards one end
thereof until the flanges 52, 82 disengage the sides 118. The box
can, of course, be orginally introduced, or re-introduced, into the
holder in the reverse manner due to the angled ends 54, 84 of the
flanges 52, 82 which feed the box into position. Alternatively the
box may be removed by depression of the thumb guide, which may be
reached through the normal opening in the box and pressed from
within the box, followed by sliding separation of the two base
members.
It is readily apparent that a more permanent locking of the box in
place could be achieved by having one or both flanges 52, 82 in the
form of serrations. The serrations might actually penetrate the box
sides to lock the box, withdrawal being achieved then only by the
latter method described above. It is also apparent that boxes can
be held with a side thereof against plates 36 and 70 so as to be
gripped at top and bottom by flanges 52, 82. With these alternative
gripping modes, it can be seen that the holder may be positioned
either horizontally or vertically on an appropriate supporting
surface so as to always present the box in the preferred
orientation.
It is also readily apparent that other forms of gripping means
could be provided so that the basic adjustment principle could be
adapted for other uses. For example the flange could be replaced by
a straight upright wall so that objects which do not readily
compress could be gripped by friction therebetween. Books, for
example, could be held in a handy vertical manner with the bound
edge up for display and promotion purposes.
A second embodiment of the present invention is illustrated in
FIGS. 7, 8, 9 and 10 wherein the flexible box holder comprises two
coactable main parts, namely a first base member 202 and a second
base member 204. The first base member comprises a rectangular base
plate portion 206 provided along each of a pair of opposite sides
with wall means 208 which extend a short distance outward of the
plate surface. Each wall means 208 is, in turn, provided with
flange means 210 spaced a short distance from the plate surface and
directed towards the flange means 210 on the opposite wall means.
An abutment wall means 212 spans one end of the plate 206,
extending between wall means 208, 208, the top surface of the
abutment wall means being coplanar with the top surface of each
flange means 210.
Extending outwardly from abutment wall 212 is a side wall 214 which
carries a flange means 216 directed inwardly of plate 206 a short
distance above abutment wall 212. As with the flanges 52 and 82 of
the preferred embodiment, flange means 216 is provided with angled
ends 218 to permit sliding sideways insertion of a flexible sided
box. As with the preferred embodiment, openings such as 220 in
plate 206 can result below the various flanges if the base member
is moulded in a single operation.
A pair of guide rails 222 are provided projecting outwardly of
plate 206 and running parallel to side walls 208. The height of
projection of each rail is less than the distance between the top
surface of plate 206 and the underside of flanges 210 and is
preferably no more than half that distance. Extending parallel to
abutment wall 212 between rails 222 are adjustment means in the
form of a plurality of parallel, tandemly oriented female ratchet
teeth 224, each having a ramp portion 226 and a locking portion
228, the teeth being directed towards abutment wall 212 (FIG. 8).
The teeth can be moulded in a depression 230 formed in plate 206
between rails 222 and the apex of each tooth should be
substantially coplanar with the top surface of guide rails 222.
As with the preferred embodiment, a pair of countersunk mounting
holes 232 can be provided in plate 206 to augment of replace any
other standard mounting means which might be contemplated.
The second base member 204 comprises a U-shaped base plate portion
234 provided with a central opening 236 and a step 238 along each
outside edge. The thickness of plate 234 is essentially the same as
the distance from the top surface of plate 206 to the underside of
flanges 210.
Each leg of plate 234 may be provided with a depression 240 in the
bottom thereof to conserve material. In addition the central
portion of plate 234 is provided with a depression 242 in the
bottom thereof which extends the full width of the central section
and actually extends into the inside edges of each leg so as to
form a bottom step 244. The depth of depression 242, and of steps
244, is slightly greater than the height of guide rails 222, which
rails are designed to mate with steps 244.
End abutment wall means 246 extends across the back edge of plate
234 and is provided with a flange 248 directed inwardly of plate
234 and having angled ends 250. The flange is parallel to plate 234
and is spaced above the plate a distance substantially equal to the
spacing of flange 216 above abutment wall 212. As with the first
base member, one-step moulding of the second base member results in
the formation of an opening 252 in plate 234 directly below flange
248.
Adjusting plate means in the form of a pair of ratchet plates 254
are cantilevered from the inside edge of central opening 236, the
ratchet plates being substantially identical and being spaced
laterally from each other as well as from the legs of plate 234.
The free end of each ratchet plate is essentially coplanar with the
free end of each leg and the bottom surface of each ratchet plate
is substantially coplanar with the exposed surface of depression
242. As best shown in FIG. 10 one of the ratchet plates 254 is
provided on its bottom surface at its free end with a male ratchet
tooth 256 having a ramp portion 260 and a locking portion 262 which
may be obtusely angled with respect to the bottom surface. Tooth
256 is designed to mate with teeth 224 as shown in FIG. 8. The
other ratchet plate 254 is provided with a male ratchet tooth 258,
having a ramp portion 264 and a locking portion 266 similar to
locking portion 262. As shown in FIGS. 8 and 10, the teeth 256 and
258 have the same height, but their apicies are displaced
longitudinally of the ratchet plates 254 by a distance 268
substantially equal to half the pitch between teeth 224. This
mechanism for interaction between teeth 224 and 256, 258 provides
for increased adjustability between the first and second base
members.
The present embodiment of the invention holds a flexible sided box
in the same manner as the preferred embodiment, namely locked
between opposing flanges 216 and 248. The adjustability is
enhanced, however, since two positions of the second base member
can be achieved with only one tooth on the first base member. As
shown in FIG. 8, tooth 256 is engaging one tooth 224, their locking
portions 260 and 228 being in a locking configuration. Due to the
relative displacement between teeth 256 and 258, the sloping
portion 264 of tooth 258 will rest on the sloping portion 226 of
the tooth 224 engaged by tooth 256, near the apex thereof. Should
the second base member be pushed inwardly of the first base member,
the apex of tooth 258 will rise along sloping portion 226 and drop
over the apex of tooth 224 so that the locking portion 226 comes
into locking configuration with the locking portion 228, just
vacated by tooth 256. At this time the sloping portion 260 of tooth
256 will rest on the sloping portion 226 of the next innermost
tooth 224 on the first base member. Thus for any one tooth 224, two
positions of the second base member, as determined by the relative
displacement of teeth 256, 258 are possible. Due to the relative
flexibility of cantilevered ratchet plates 254 the second base
member can be withdrawn from engagement with the first base member
by applying an outward separation force on the second base member
relative to the first base member whereby teeth 256, 258 ride up
and over teeth 224.
Since the disengaged tooth 256 or 258 is in a position to engage
itself with the female tooth as it approaches its engaged position,
it is seen that the two male tooth system prevents the teeth from
jumping or skipping engagement positions and opening the base
members more than desired. It is also apparent that the separation
force desired can be set in manufacture by having the locking
portions 262, 266 make appropriate angles with the bottom surface
of ratchet plates 254.
A third embodiment of the present invention is illustrated in FIGS.
11, 12 and 13 wherein the flexible box holder comprises two
coactable main parts, namely a first base member 302 and a second
base member 304. The first base member 302 is very similar to first
base member 202 of the second embodiment and has a rectangular base
plate portion 306 provided with side walls 308, inwardly directed
side flanges 310, transverse abutment wall means 312 with end wall
314 and end flange 316 thereon. The flange 316, as before, has
angled ends 318 to aid sliding sideways insertion of a flexible
sided box. A pair of longitudinally directed parallel guide rails
320 project outwardly from the top surface of plate 306, the height
of projection approximating the outward spacing of flanges 310.
As with the second embodiment, adjustment means in the form of a
plurality of parallel, tandemly oriented ratchet teeth 322 extend
transversely between rails 320, but these teeth differ from those
previously described in that they have two sloping portions 324,
326 instead of just one such portion. Thus, as shown in FIG. 12,
each tooth has a cross-section approximating an isosceles triangle
rather than a cross-section approximating a right angle triangle,
as do the teeth of the previous embodiments.
A pair of countersunk mounting holes 328 may be provided in plate
306 to aid in mounting the holder of the present embodiment to an
appropriate supporting surface.
The second base member 304 is similar to second base member 204 in
that it comprises a generally U-shaped base plate portion member
330 having a pair of legs 332 flanking a central opening 334. The
outer edges of legs 332 are provided with steps 336 for sliding
within the space between plate 306 and flanges 310 and abutment
wall means 338 bridges the outermost edge of the cross-piece
joining legs 332. A flange 340 projects towards opening 334 from
abutment wall means 338, flanges 340 and 316 being spaced above
plate 330 and abutment wall 312, respectively, by substantially the
same amount. As with flange 316, flange 340 has angled ends
342.
As shown in FIGS. 11 and 12, adjusting plate means in the form of a
ratchet plate 344 is cantilevered from the cross-piece joining legs
332 and is centrally oriented with respect to opening 334. In the
form of this embodiment illustrated, plate 332 is sized so that its
bottom surface will engage the top surface of rails 320 and hence,
as shown in FIG. 12, the top surface of ratchet plate 344 is
actually coplanar with the bottom surface of plate 330. If plate
330 were formed in a manner analagous to plate 234 of the second
embodiment, i.e. with guide steps analogous to steps 244, then the
ratchet plate 344 could be cantelevered to the inside cross edge of
the plate 330, just as ratchet plates 254 are cantelevered to plate
234.
On the bottom surface of ratchet plate 344, at the free end
thereof, is a transverse ratchet tooth 346, with sloping portions
248 and 250 (FIG. 12). In operation the tooth 346 mates with teeth
322 to lock the second base member relative to the first base
member to secure a flexible sided box between flanges 316 and 340.
Because of the sloping surfaces 324, 326 and 348, 350 adjustment of
the base members relative to each other is quite easy, although
more spring action of the cantilevered ratchet plate 344 is
required to ensure effective engagement of the ratchet teeth.
In all of these embodiments it is seen that the first base member
forms a track in which the position of the second base member may
be adjusted. By having appropriately sized base members any size of
flexible container can be held.
Two further embodiments exhibiting the inventive features of the
preferred embodiment are illustrated in FIGS. 14 to 22. Each of
these embodiments comprises first and second coactable base
members, box gripping means on each base member and adjusting means
on the base members for spacing the gripping means apart by a
predetermined distance.
The embodiment of FIGS. 14 to 18 is shown in perspective in FIG. 14
as comprising a pair of coactable, mutually adjustable base members
402 and 438. Base member 402 has a generally planar base plate
portion 404 provided with a central rectangular opening 406. A
stepped portion 408 extends along one longitudinal edge of the base
plate adjacent opening 406, portion 408 being spaced outwardly a
short distance from plate 404 and being parallel thereto. Abutment
wall means 410 extends across the outermost longitudinal edge of
portion 408 and projects outwardly therefrom. A pair of box
gripping means on flanges 412 are directed parallel to portion 408
towards opening 406 and, as in the previous embodiments, they have
angled ends 414. It is understood that any number of flanges, or
even a plurality of gripping teeth, could be utilized in place of
the pair of flanges 412.
Surface 416 slopes from the outermost edge of abutment wall 410
outwardly so that its opposite edge is generally in line with the
bottom surface of plate 404. This surface is of sufficient size to
accept advertising information, instructions for use of the holder,
or other printed matter. As shown in FIGS. 15 and 16 stepped
portion 408 and surface 416 are supported by a plurality of
intersecting ribs 418 and 420. These ribs are utilized to
strengthen the structure, providing rigidity as well as a framework
for receiving the covering thereover to complete stepped portion
408 and sloping surface 416. It is understood that this
construction permits integral moulding of the first base member and
extreme rigidity. Should the base member be integrally moulded,
openings akin to openings 108, 114 or 220 would appear in portion
408 below flanges 412.
Mounting holes 422, which may be countersunk are provided in
stepped portion 408.
Cantilevered from stepped portion 408 over opening 406 is an
adjusting plate means 424 whose top surface is essentially coplanar
with the top surface of portion 408. On the under surface of plate
424 and facing opening 406 are a plurality of tandemly oriented
alternating parallel ribs 426 and grooves 428, the ribs and grooves
extending longitudinally of plate 424. The use of the ribs and
grooves will become apparent in the discussion of the operation of
the flexible box holder of this embodiment.
Spaced outwardly from the ends of plate 424 are a pair of
crescent-shaped cut-outs 430 in plate 404 the legs of which are
directed away from plate 424. Contained within each cut-out is a
tab portion 432 of plate 404, which portion has a limited degree of
flexibility. Stops 434 extend outwardly from tabs 432 and extend
around a portion of the periphery thereof, although the shape of
stops 434 is not critical to the invention. As shown in FIG. 18,
the flexibility of tabs 432 may be enhanced by having the thickness
thereof less than that of plate 404.
Extra mounting holes 436 can be provided in base plate 404 to aid
in mounting the first base member 402 to a supporting surface.
Second base member 438 is provided with adjustment means such as
plate 440 specifically adapted for coaction with adjusting plate
424. A plurality of spaced, parallel ribs 442 extend longitudinally
of plate 440 adjacent one edge thereof, the spacing between ribs
442 being no less than the thickness of ribs 426 and the thickness
of ribs 442 being no greater than the width of grooves 426. As is
apparent from FIGS. 14 and 15, ribs 442 are mutually engageable
with ribs 426 and grooves 428. In order to ensure a solid fit
between adjusting plates 424 and 440 the distance from the
underside of plate 440 to the top of ribs 442 should be very close
to the distance from the top of plate 404 to the base of grooves
428.
As is best shown in FIG. 14, plate 440 has sloping ends 444 and has
a length slightly less than the minimum distance between tabs
432.
A stepped or raised portion 446 abuts the edge of plate 440
opposite ribs 442 and has a length approximating that of plate 404.
It is seen that portion 446 has a height such that it is coplanar
with portion 408 in the assembled state illustrated in FIGS. 14 and
15. Extending upwardly from the opposite longitudinal edge of
portion 446 is abutment wall means 448 which carries inwardly
directed box gripping means 450 which may be in the form of the
flanges shown, the flanges having angled ends 452.
A sloping surface 454, akin to surface 416 is provided, running
outwardly from abutment wall 448. As with first base member 402,
the second base member may be constructed with a plurality of
intersecting ribs 456, 458 underlying portion 446 and sloping
surface 454.
The use of the flexible box holder of the present embodiment will
now be described. A box to be held is first measured by placing one
side to be held in line with edge 462 of the second base member
such that the opposite side falls in the vicinity of indicia 460
placed on the top of raised portion 446. The lowest number that can
be seen adjacent the box side is the adjustment number and it has a
corresponding number amongst the indicia 464 which appear on
adjusting plate 424. Each number of indicia 464 corresponds to one
of the grooves 428.
If the two base members 402 and 438 are not assembled together,
assembly is effected by inserting ribs 442 into grooves 428 such
that the outermost rib is received in the groove bearing the number
corresponding to the number selected in the first step. Insertion
of the adjusting plate 440 into engagement with plate 424 is
enhanced by sloping ends 444 which guide the plate 440 into
position. Due to the reasonably tight fit of the adjusting plates
therewill be negligible tilt between the base members during
assembly and hence the tab 432 at the assembly end will be
depressed by the plate 440 sufficiently to permit assembly. Plate
440, and second base member 438, are locked after assembly between
stops 434 on tabs 432. In order to disassemble the box holder it is
necessary to depress one of the tabs 432 to lower the associated
stop below the bottom surface of plate 440 so that the plate 440
can be slid thereacross to utlimately disengage ribs 442 from
grooves 428.
The present embodiment provides a very secure adjusting mechanism
which can be used to space gripping means 412, 450 a predetermined
distance apart, that distance being directly related to the size of
box to be held. The box 466 is inserted by sliding it, on coplanar
portions 408, 446 so that the flexible sides thereof are engaged by
gripping means 412, 450 in the same manner as with the preferred
embodiment.
The fifth embodiment of the present invention is illustrated in
FIGS. 19 to 22 inclusive and comprises two adjustable coactable
base members 502 and 526. First base member 502 comprises a base
plate portion 504 provided along one edge thereof with an
upstanding end wall 506 having an inwardly directed box gripping
means in the form of a flange 508 having angled ends 510, flange
508 being spaced a fixed distance from and generally parallel to
base plate 504.
Along the opposite edge extends upstanding abutment wall means 512
provided with cantelevered adjusting means such as plate 514
extending toward flange 508 parallel to base plate 504. Adjusting
plate 514 has a plurality of alternating ribs 516 and grooves 518
in the undersurface thereof, the ribs and grooves being parallel to
abutment wall 512.
A tab insert 520 has a width approximately the same as adjusting
plate 514 and extends therebeneath along the full length of
abutment wall 512. A pair of U-shaped cut-outs 522 in insert 520
define flexible tabs 524 which are resiliently biased outwardly of
plate 504. The tabs 524 seen in FIG. 19 lie outwardly of plate 514
and serve the same purpose as tabs 432 in the fourth
embodiment.
Second base member 526 is also of a simple construction, having an
adjustment means or plate 528 adapted to coact with plate 514, it
length being slightly less than the spacing between tabs 524. A
plurality of spaced ribs 530 are provided on the upper surface of
plate 528, one of the ribs preferably being along the outermost
edge thereof, the spacing of ribs 530 being no less than the width
of ribs 516.
Extending along the opposite edge of plate 526 is a support or
abutment wall 532, the length of which is substantially the same as
wall 506. Support wall 532 has a foot portion 534 of the same
thickness of insert 520 and box gripping means 536 cantelevered
therefrom along the top edge thereof. Gripping means 536, shown in
the form of a flange, is analagous to flange 508 and with the
second base member assembled to the first base member the flanges
508 and 536 are coplanar as shown in FIG. 22. Flange 536 has angled
ends 538 as do the other flanges described herein.
Assembly, use and disassembly of the present embodiment is the same
as for the previous embodiment the only difference being that the
adjusting means are not contained between the box gripping means.
This means that at least the first base member must be larger but
this is offset by the increased surface area for advertising
slogans, etc. It is noted that the indicia for determining the
proper location of the second base member relative to the first
base member are not shown in this embodiment although such indicia
are usable.
It should be understood while the present invention has been
described with respect to tissue boxes it is equally useful in
holding any container having at least a portion of the sides
thereof deformable or penetrable by the gripping means and that
with proper gripping means it will even hold objects, such as
books, by frictional engagement therewith.
