Description
BACKGROUND OF THE INVENTION
This invention relates to an improvement in reclosable plug type
dispensing package, and deals particularly with a container capable
of containing tissues and the like, and which may be reclosed when
desired.
Tissues and the like are normally contained in rectangular
paperboard cartons having a removable area in the top panel through
which the uppermost tissue may be grasped and removed. In recent
years, tissues have been developed for different purposes. In other
words, tissues impregnated with an oily material have been
developed for use in polishing furniture and the like. Other types
of tissues impregnated with other liquid materials have also been
developed.
The difference between the packaging of dry tissues and tissues
which contain a liquid material, mainly lies in the particular
impregnating materials which are used. For example, a paperboard
carton may be coated with a coating resistant to the liquid
material impregnated in the tissues. However, if, during the
cutting and creasing operation the coating is cracked or disrupted
in any way, the liquid material will be absorbed into the
paperboard. Furthermore, it is difficult to provide a liquid tight
closure in a corrugated carton so that the package may be reclosed
after use.
SUMMARY OF THE INVENTION
I have found that an effective package may be formed with a
combination of plastic and paperboard parts. The main body of the
package being an object where the cleaning operation requires a
damp or liquid impregnated cloth or wiping tissue, and where a
suitable amount of liquid is necessary to clean or polish the
surface. These packages differ from the conventional tissue
packages in that the entire inner surface of the containing package
must be resistant to the liquid with which the tissues are
impregnated. Normally, if the package is not reclosed after a
tissue has been removed, the liquid impregnated in the tissues or
other moist contents will evaporate, leaving the tissues
impractical for their intended purpose. It is the purpose of the
present invention to provide a package which is formed of material
which will not be affected by the liquid contained in the product
packaged, and which may be reclosed to form a seal which will
effectively prevent the evaporation of the liquid when the package
is reclosed.
A feature of the present invention resides in the provision of a
package including, in preferred form, a tray of sheet plastic or
the like having an outwardly turned peripheral flange on a common
plane about the periphery of the tray walls at the upper ends
thereof. A cover panel is sealed to the peripheral flange about its
entire periphery so as to hermetically seal the contents. The tray
includes a flap structure supporting a resilient plug which may be
inserted through the dispensing opening in the cover panel. The
dispensing opening is normally formed by an endless perforated line
so that the area within the perforated line may be detached from
the opening. The cover panel may be formed of paperboard which is
coated with a coating which is impervious to the liquid contained
within the package. In this respect, the structure is quite similar
to the usual form of tissue dispensing packages. However, the flap
structure is hingedly connected to one edge of the cover panel, and
includes a pair of flap sections, one of which forms a side wall,
and another of which forms a resilient plug supporting member. The
edge of the cover panel which is opposite that to which the flap
structure is secured preferably is provided with a tapered side
wall which extends along the side wall opposite the first mentioned
side wall, a bottom wall which is secured to the bottom of the
interior plastic tray, and a glue flap which is secured to the
bottom of the interior plastic tray, and a glue flap which may be
secured to the side wall forming a part of the flap structure to
form a wrapper enclosing the plastic tray having outwardly
projecting peripheral flanges. The cover panel is sealed to these
flanges, the first side wall and plug supporting wall hinged to one
edge of the cover panel, and a second side wall and bottom panel is
secured to the opposite edge of the cover panel. A glue flap on the
bottom panel folds outwardly of the side wall forming a portion of
the flap structure thus forming a wrapper which may be rectangular
or trapezoidal in cross section. When the dispensing opening has
been opened, the side wall forming a part of the flap structure may
be disconnected from the glue flap on the bottom panel, and the
flap structure may be folded to fold over the cover panel, and the
plug supporting panel may extend over the dispensing opening, and
the plug may be inserted into the dispensing opening to effectively
seal the same.
A further feature of the present invention resides in the fact that
an additional panel or section may be hinged to the plug supporting
section and through which the plug may be inserted. The plug may be
provided with an outwardly extending peripheral flange which may be
sandwiched between the plug supporting panel and the additional
panel.
These and other objects and novel features of the present invention
will be more clearly and fully set forth in the following
specification and claims .

DESCRIPTION OF THE PREFERRED EMBODIMENT
In the particular form of construction, the package, which is
indicated in general by the letter A, includes a tray shaped
receptacle B and a wrapper or folder C. The tray B is preferably
formed of sheet plastic or the like and includes a bottom wall 10,
upwardly and outwardly inclined end walls 11, and upwardly and
outwardly inclined side walls 12. The side and end walls are
integrally connected at the corners. A flange 13 extends outwardly
from the upper ends of the side and end walls on a common
plane.
The wrapper C includes a top panel 14 having an endless weakened
line of separation 15 which, when broken away from the remainder of
the top panel 14, forms an opening 16 (see FIG. 2). Connected to
one edge of the top panel 14 along a hinge line 17 is a first
tapered side wall panel 19. A plug supporting panel or section 20
is hingedly connected to the side wall 19 along a fold line 21
which is parallel to the fold line 17. The plug supporting flap 20
is connected to a reinforcing flap 22 along a fold line 23. The
reinforcing panel 22 is provided with an aperture 24 through which
the plug or stopper may extend. The side wall panel is of
trapezoidal shape, connected along its longer edge to panel 14 and
along its shorter parallel edge to flap 20.
The opposite edge of the generally rectangular top panel 14 is
connected by a fold line 25 to a side wall panel 26. The side wall
panel 26 is trapezoidal in shape. The side wall panel 26 is
connected at its shorter parallel edge along fold line 27 to a
bottom panel 29. The sealing flap or glue flap 30 is connected
along the edge of the bottom wall 29 along a weakened line of
separation 31. All of the fold lines which have been described are
in parallel relation.
The inner surface of the wrapper C is preferably formed of
paperboard coated with a coating capable of being heat sealed to
the flange 13 of the tray B. Alternatively, the flange 13 may be
adhered to the top panel 14 of the wrapper and the top panel
adhered or cemented thereto.
The original package A in its simplest form is formed by sealing
the under surface of the top panel 14 to the flange 13. The under
surface of the top panel 14 is coated with a composition which is
impervious to the moisture which is impregnated in the stack of
tissues indicated in general by the letter D. The tray B is also
formed of a material which is nonaffected by the liquid content of
the tissues. While the stack of tissues D normally comprise liquid
impregnated tissues which may be dispensed one at a time, quite
obviously the package is capable of holding other products having
liquid therein or thereon. In the closed form of the package, the
bottom wall 29 of the wrapper C is adhered to the bottom wall 10
and the flap 30 is folded against the outer surface of the side
wall 19 and adhered thereto. The side wall 19, the plug supporting
panel 20, and the reinforcing panel 22 form a flap structure
connected to the top panel 14 along the fold line 17. As is
indicated in FIG. 4 of the drawings, the plug 35 includes a bottom
closure panel 36 which is completely encircled by side walls 37
which taper in form, the periphery of the plug most remote from the
closure panel 36 being smaller than the periphery of this wall
adjoining the closed ends 36. Thus in inserting the plug through
the opening 16, the plug must flex sufficiently to extend through
the aperture which is of somewhat smaller periphery than the
periphery of the plug near the closed end 36. An outwardly turned
flange 39 entirely encircles the smaller periphery portion of the
side walls 37.
In forming the device, the plug 30 is preferably secured to the
under surface of the flange 20, and the reinforcing panel or
section 22 is folded against the section 20 and secured in face
contact therewith, sandwiching the flange 39 between the panels 20
and 22. The panels 20 and 22 which have been secured together are
folded upwardly from the lower edge of the side wall panel 19 as
indicated in dotted outline in FIG. 4 of the drawings, and the
locking or glue flap 30 is secured to the outer surface of the side
wall 19. After the perforated area has been separated from the top
panel 14, and a tissue or other object contained removed, through
the aperture 16, the package may be reclosed by tearing the tab
from the bottom panel along the weakened line of separation 31.
When the combined panels 20 and 22 are alined with the wall panel
19, the plug 35 may be snapped through the aperture 16, reclosing
the carton with a tight seal as indicated in FIG. 3 of the
drawings.
In accordance with the Patent Statutes, I have described the
principles of construction and operation of my "Reclosable Plug
Type Dispensing Package;" and while I have endeavored to set forth
the best embodiment thereof, I desire to have it understood that
obvious changes may be made within the following claims without
departing from the spirit of my invention.
