DESCRIPTION OF SPECIFIC EMBODIMENTS
Referring more particularly to the drawings in which like reference
characters indicate like elements throughout, in FIG. 1 there is
shown a fully opened box-like receptacle having bottom panels 10
and 10' divided by hinge 11 defined by fold lines 11' that extend
to the upper or free margin of oppositely disposed upstanding side
wall panels 13 and 13'. The receptacle contains upstanding end wall
panels 18 and 18', each of which has, at each end, a corner tab
(i.e., 20, 20', 20', and 20'") that is adhered (as by being glued)
to its adjacent inner surface of the side walls 13 and 13'. As
shown, each of the upstanding walls contains a serrated perforation
15 adapted, when the inside of the receptacle is lined with a
disposable liner bag such that the ends of the open mouth of the
bag overlap the upper margins of the walls 18, 18', 13 and 13', the
overlapped portions of the bag can be tucked into the perforations
15 to hold the liner in place.
FIG. 2 shows a top plan view of a blank useful for forming the
package receptacle of FIG. 1 from a single rectangular blank, cut
and scored as shown. The blank contains substantially parallel
spaced apart fold lines 11' to provide hinge 11 and a pair of
substantially parallel spaced apart fold lines 16 and 16',
substantially perpendicular to hinge 11. Fold line 16' divides the
blank in a manner to provide panels 20. 13' and 20' on one side of
fold line 16', panels 18, 10', 10 and 18' in between fold lines 16
and 16', and panels 20", 13' and 20'" on the other side of fold
line 16. As shown, panels 20 and 20" are tabs at each of the end
portions of panel 18, and 20' and 20'" are tabs on each of the end
portions of panel 18'. Each of the tabs (i.e., 20, 20', 20" and
20'") is provided with a fold line 21, as shown, and, as further
shown, panels 13 and 13' are also provided with fold lines 14 and
14' respectively.
By use of a blank as shown in FIG. 2, the receptacle of FIG. 1 can
be formed by folding the blank at folds 17 in a manner such that
panels 18 and 18' form substantially upstanding walls perpendicular
to bottom wall portions 10' and 10 and by folding each tab (20,20',
20" and 20'") at its fold line 25 inwardly such that each of the
tabs is substantially perpendicular to its adjacent portion of
panel 18 and 18'. The blank is then further folded at lines 16 and
16' to provide upstanding walls 13 and 13' substantially
perpendicular to bottom panels 10 and 10' such that tabs 20, 20',
20'" are disposed adjacent their corresponding inside surface of
panels 13 and 13'. By gluing, or other appropriate means, each of
the tabs is adhered to its adjacent inner surface of panels 13 and
13' to form the corners of the receptacle when fully opened. The
receptacle, when it is desired to collapse it into a book-fold
receptacle, can be provided in collapsed form, by forcing
oppositely disposed end panels 18 and 18' towards each other
whereby fold lines 14 and 14' collapse inwardly, and upon folding
at hing 11 such that walls 18 and 18' are forced towards each
other, the receptacle in book-fold form (as shown in FIG. 5) is
provided.
Although, as an embodiment, means 15 are shown as serrated
perforations in the walls of the package receptacle of FIG. 1, such
means may be of other configurations of slits or holes.
Non-limiting examples of types of attaching means include straight,
arced or angled smooth slits at horizontal or skew orientations,
serrated or saw-tooth slits at horizontal or skew orientations,
round holes, and others. Such means may be in both the side and end
walls or in either the side or end walls of the package receptacle.
A preferred embodiment is, as shown in FIG. 1, disposition of means
15 substantially in the center of each of end walls 18 and 18', in
one end portion of side panel 13 and, in side panel 13'.
FIG. 3 of the drawings shows a perspective view of a disposable
gussetted waterproof liner bag 22 for use in lining the opened
package receptacle of FIG. 1. Such a bag 22 may be produced from
any suitable material with a particularly suitable material being a
thermoplastic material such as polyethylene. Specifically, the
liner bag may be fabricated from a long tubular section of
thermoplastic material, folded, cut and heat sealed such that
gusset folds 23 and 23' are formed and the bottom closed end of the
bag sealed at 24. The liner bag side walls 28 should be long enough
such that, when the bag 22 is placed inside the fully opened
package receptacle of FIG. 1, they overlap the side walls 13 and
13' and end walls 18 and 18' of the package (as shown in FIG.
4).
FIG. 4 shows a perspective view of a ready for use sanitary
container comprising the fully opened collapsible package
receptacle of FIG. 1 with a disposable liner bag 22 as described in
FIG. 3 in place. The package receptacle is lined with the bag such
that the side walls 28 of the open end of the liner bag are folded
over the top edge of the side walls 13 and 13' and end walls 18 and
18' of the package. Portions 26 of the folded over portion of the
liner bag are securely held in place to effectuate a useful
sanitary container by tucking said portions 26 into their adjacent
attaching serrated perforation means 15.
FIG. 5 of the drawings shows a perspective view of a collapsible
package receptacle, of the embodiment of FIG. 1, in a fully closed
position. The package receptacle in this position is substantially
flat and compact and is convenient for storage in the home or on a
store shelf when being sold. It is shown in this drawing how side
wall panels 13 and 13' fold in toward the center of the package
receptacle when segments 12 and 12', comprising bottom panels 10
and 10' and end panels 18 and 18', respectively, are brought
together in a collapsing manner about hinge section 11. End wall
panels 18 and 18' also fold in toward the center of the package
receptacle when it is closed.
In the collapsed form of FIG. 5, a suitable liner (as the bag of
FIG. 3) or a plurality of such liners can be stored inside of the
collapsed receptacle. The liners are held inside of the collapsed
receptacle substantially between the bottom panels 10 and 10' and
the inwardly folded side wall panels 13 and 13' and end wall panels
18 and 18'. Such a combination of the collapsed receptacle with a
plurality of liner bags held inside of the collapsed receptacle is
a highly suitable means combination for marketing, shipping or
other handling of the receptacle-liner combination. To prevent
undesired opening of the receptacle when it is desired to maintain
it in collapsed form, the receptacle may be kept in the collapsed
form of FIG. 5 by use of type 27 or other suitable means, as shown
in the embodiment of FIG. 5, to restrain the receptacle against
opening.
It will be appreciated that the sanitary container useful as a pet
animal toilet station illustrated and described herein is a
particularly neat and useful item in that it makes any necessary
handling of any absorbent materials normally used in such
containers much more convenient. The sanitary container is
self-packaging and can be provided at a very low cost. Since only
the liner bag need be disposed of, the package receptacle of
book-fold type, which may be made of stiff paperboard sheet
material and the like, may be used repeatedly with liner bag
replacement. This sanitary container will be found to be
particularly useful when traveling or vacationing with pets.
Although the present invention has been described with preferred
embodiments, it is to be understood that modifications and
variations may be restored to, without departing from the spirit
and scope of the invention, as those skilled in the art will
readily understand.
