SUMMARY OF THE INVENTION
Generally speaking, the invention of the present application provides a sealed
package storage device comprising a base member having at least one package-
receiving
storage region, and one or more sealed packages that are each located in a
respective
package-receiving storage region. Each sealed package has an opening that has
been
covered with a removable cover at a surface surrounding the opening. The
sealed package
contains a single shaving cartridge and the cover is removable from the
surface upon the
application of a removing force greater than a predetermined removal force
value. Each
package-receiving storage region provides a retention force to retain a
respective package
within the package-receiving storage region, the retention force being less
than the
predetermined removal force value.
Embodiments of the invention may include one or more of the following
features. In
certain embodiments, the base member of the storage device can carry a surface-
mounting
structure, for a horizontal surface or a wall, such as double-sided adhesive
tape, suction
cups, or openings in the base member for receiving transverse mounting members
attached
to a wall. The base member is formed of plastic and has a side wall that
extends around its
periphery. The base member has dividers formed therein to provide a plurality
of
compartments along with the side wall. The dividers each have a flat portion
at a free end
of the divider, the flat portion receiving a lip that extends from one side of
the package
retained in the compartment. The dividers each also have a ridge that is
formed between
the base and the free end for receiving a narrow edge portion of the package.
The dividers
extend only part way from the side wall at one side of the base member to the
side wall at
the other side to provide a region for gripping an exposed portion of the lip
of the package.
The dividers have opposed members for retaining the packages. One of the
opposed
members has a sharp portion that engages the package. One of the opposed
members can
have spring flexure. The dividers have drainage openings, and the side wall
has a drainage
opening at the bottom of the base member. The base member has projections
between the
dividers to position the packages.
In other embodiments, the cover of the base member is hingedly connected to
the
base member by a snap-fit connection. The cover has an opening that engages
the bottom
of a razor handle and opposed flexible wings that engage the razor head end of
the handle.
The cover has a raised portion that matches the contour of one side of a razor
handle. The
2
CA 02509431 2000-07-24
The cover has a raised portion that matches the contour of one side of a razor
handle. The
cover has a flat area to provide clearance for the cartridge attached to a
handle supported
on the cover. The cover is made of softer plastic than the base member. The
cover has
a snap-fit closure member and a finger engagement lip extending from the cover
for
opening the cover. Embodiments of the invention may include one or more of the
following advantages. Shaving cartridges packaged in sealed containers, to
protect them
from water and cleaning agents, are stored in a storage device that can be
conveniently
mounted on a bathroom shower wall. The sealed packages are securely retained
prior to
removal, and can be easily gripped at exposed corners. The sealed packages are
safely
removed from the storage device in normal use without risk of the peelable
film being
removed prematurely. The shaving razor can be conveniently and securely
mounted on
the outside of the cover for easy removal and replacement without the need to
open the
cover. Drainage openings prevent water from collecting in the device.
Other advantages and features of the invention will be apparent from the
following
detailed description of particular embodiments of the invention and from the
claims.

DETAILED DESCRIPTION OF THE INVENTION
Referring to Figs. 1, 2 and 3, there is shown wall-mounted storage device 10
for a
shaving razor 12 that is supported on the outside of device 10, and
replacement cartridges
13 in a sealed package 14 that is stored inside device 10. Cartridges 13 each
have a
plastic housing and a plurality of blades. Sealed packages 14 have airtight
seals to keep
moisture and cleaning agents from cartridges inside the packages. Cartridge 13
is not
substantially flat and has a complex, non-planar shape with many different
contours.
Sealed package 14 sufficiently surrounds those contours and acts as an air and
moisture
barrier.
Storage device 10 includes base member 16, made of ABS, and cover 18, made of
polypropylene. Base member 16 is made of a hard plastic to provide structural
integrity
for the mounted member. Polypropylene provides a desired appearance for the
cover, and
facilitates use of a snap-fitting hinge. Base member 16 is adhered to bathroom
tiles 20 on
wall 22 via double-sided adhesive pads 24 (Fig. 3) made of foam pads and
acrylic adhesive.
Cover 18 is hingedly connected to base member 16 via snap-fit hinge members
21. Cover
18 has finger engagement lip 23 to assist in opening cover 18 and to provide
sufficient
force to overcome the snap (interference) fit closure mechanism used to keep
cover 18
closed. (Alternatively a latch structure could be employed to keep cover 18
closed.). The
upper part of handle 15 of shaving razor 12 is engaged by wings 26 formed on
the exterior
surface of cover 18, and the bottom of handle 15 sits within opening 28 in
cover 18. Razor
12 rests on cover 18.
Referring to Figs. 4 and 5, it is seen that base member 16 has three dividers
30,
which, along with side walls 32 and upper support 36 and lower support 38,
define
compartments for receiving four sealed packages 14. In Figs. 4 and 5, a single
package
14 is shown in the second compartment from the bottom. Each divider 30 has a
flat outer
surface 40 at an end thereof against which lip 43 (Figs. 5 and 8) of package
14 rests. As
is seen in Figs. 4 and 8, the two sides of the lip 43 extend beyond divider 30
or lower
support 38 at adjacent plastic tabs 72, providing access for a user to grip
and remove
package 14. Prior to opening of the packages, tabs 72 in effect are extensions
of lip 43.
The upper surface of each divider 30 and of lower support 38 has a retention
member 42
that presses against the bottom of package 14 and holds it against the
opposing flat
4
CA 02509431 2000-07-24
surface 44 of the next higher divider 30. Retention member 42 advantageously
has a
sharp edge that digs into the softer plastic of package 14. Retention member
42 and the
opposed flat surface 44 function as opposed members that provide a retention
force to
opposite sides of a package 14 within a compartment. While retention members
42 are
hard, they alternatively could be spring-biased. Each compartment also has a
pair of
projections 46 which space the bottom of the package 14 away from the wall in
the desired
position (Fig. 5). The upper portion of each divider 30 and lower support 38
has an
opening 48 for drainage of water. Flat surface 44 has a ridge 52 at its outer
end that
receives an edge 54 of sealed package 14 (Fig. 5). Base member 16 also has
four
through-holes 56 to permit mounting on pins extending from a mounted base
plate or to
permit mounting by screws or other fasteners. Base member 16 has drainage
opening 57
at the bottom.
Referring to Figs. 6 and 7, cover 18 has support surfaces 60, 62 that tend to
conform to the back surface of razor handle 15, which is designed for use by
women in
shaving underarms and legs. The handle is shown in U.S. Des. Patent No.
407,851. The
bottom of handle 15 is engaged in and supported by opening 28, and the upper
portion of
handle 15 is located in the space between wings 26 and outward of support
surface 62 and
is engaged by wings 26. A flat portion 64 is provided at the upper end of
cover 18 for
providing clearance for the blade unit of the attached shaving cartridge 13.
The back
surface of handle 15 closely matches and is close to the outer surface of
cover 18. The
user grips the sides of handle 15, as there is insufficient room for a user's
fingers to grip
the back surface of handle 15.
Referring to Fig. 8, sealed package 14 includes a plastic container 68 and
peelable
cover sheet 70 that is sealed to container 68 to cover and closes the entrance
to the
storage region for cartridge 13. Gripping tab 72 is attached to a corner of
cover sheet 70
at an end of lip 43 for use in initiating peeling of cover sheet 70.
In use, storage device 10 is secured to bathroom tiles 20 of wall 22 (e.g., in
a
shower) by removing a cover layer on double sided-adhesive pads 24 and
applying
pressure to device 10 to cause a good bond between the adhesive and the tile
surface. The
user removes razor 12 when shaving and can store it on cover 18 between uses.
When
removing razor 12, handle 15 is grasped on the lateral sides of the razor, is
slipped
outward through support wings 26, and is raised upward from its rest position
in opening
28. When placing shaving razor 12 back on cover 18, the bottom of handle 15 is
placed
in opening 28, and the upper portion of handle 15 is guided between wings 26
and held in
5
CA 02509431 2000-07-24
place. When it is time to replace the shaving cartridge 13 on handle 15 with a
new
cartridge 13, cover 18 is opened by engaging finger grips 23, and a sealed
package 14 is
removed by engaging the tab 72 adjacent to lip 43. Cover 18 is then closed.
The user
then peels open cover sheet 70 (see Fig. 8) and attaches the new cartridge 13
to handle
15. Cover sheet 70 is attached to container 68 by a seal that has a
predetermined initial
peel force value needed to open the package. That value is five times higher
(preferably
ten times higher) than the retaining force provided by retention members 42 to
retain
packages 14 in their respective compartments in base member 16. E.g., the
initial peel
force could be 3-5 pounds, and the retaining force on packages 14 could be as
little as one
ounce. Thus, packages 14 will not accidentally open upon (or prior to) removal
from base
member 16.
Other embodiments of the invention are within the scope of the claims. For
example, device 10 could be connected to wall 22 via suction cups instead of
adhesive pads
24. Also, storage device 10 could be mounted (or simply supported) in a
horizontal
position on a horizontal surface, and could also be used as a carrying case.
Also, instead of directly mounting storage device 10 to the wall, it could be
removably mounted on a wall-mounted plate, as is shown in Figs. 9-11.
Referring to Figs.
9-11, plate 100 has posts 102 with enlarged heads 104 that are received in the
circular,
lower portions of slotted openings 106 on base member 108, the narrow shafts
109 of
posts 102 are locked in place in the tapered, upper portions of slotted
openings 106.
Tapered blade projections 110 on plate 100 fit within recesses on the back
sides of the
upper two dividers 30 of base member 108 in order to guide openings 106 to the
locations
of posts 102. Blade projections 110 also prevent base member 108 from being
forced
downward too far to avoid jamming or breaking of posts 102 during attachment.
Plate 100
also has a rectangular opening 112 and is sized so that the plate can be
contained within
storage device 10 prior to mounting on a wall. When plate 100 is contained in
device 10,
a divider 30 projects through opening 112.
