Description
This invention relates to a package dispenser for razor blades.
In the past, various types of packages for razor blades including
dispensers have been devised. These prior dispensers have been
provided with mechanical arrangements for facilitating the manual
or automatic dispensing of razor blades from the dispenser with the
automatic mechanisms being used to set the blades in the razor. At
least some of the dispensers had provision for receiving used
blades therein.
With the introduction of the razor blades such as disclosed in the
U.S. Pat. to Fishbein, No. 3,071,856, issued Jan. 8, 1963, entitled
"Razor Blade and Method of Making Same" and the U.S. Pat. to
Hansom, No. 3,388,831, issued June 18, 1968, for "Shaving Units and
Dispensers Therefor," the dimensions of this type individual blade
became much larger. More particularly, blades are of a substantial
thickness as compared with, for example, a conventional double edge
safety razor and employ only a thin strip of metal such as
stainless steel, chromium alloy, or the like, which may have a
coating such as that disclosed in U.S. Pat. No. 3,071,856. These
blades are mounted in a magazine-type dispenser for sequential
dispensing and, as disclosed in U.S. Pat. No. 3,388,831, they are
automatically seated in the razor after the previous blade has been
released therefrom. The magazine-type dispenser is provided with a
very strong spring due to the bulkiness of the blades to provide
for effective biasing action while taking into account the
thickness of the blades as they are successively dispensed. This
spring is of itself of considerable size and heretofore it has been
necessary to utilize a comparatively large size dispenser for
housing the spring and blades which did not have any means for
receiving therein used blades. Further, the razors of this specific
type employ a relatively powerful spring for automatically ejecting
the used blade and, when ejected, the blades may strike a surface
such as a wash basin or stand and bounce into an awkward location
for retrieving thereof or may rebound against the person of the
user so as to subject the user to a possible injury.
The present invention overcomes the disadvantages of the lack of
storage space for used blades by providing for an arrangement
whereby relatively strong springs having a wide range of expansion
and contraction can be employed, yet which requires only a minimum
amount of space as compared to the prior art springs thereby
permitting the used blade to be ejected automatically and directly
into a used blade compartment of the dispenser without requiring
any increase whatsoever in the overall size of the dispenser.
The concept of this invention features the use of double volute
springs arranged in pairs and mounted on suitable truncated conical
studs so as to eliminate the possibility of bending or twisting of
the springs, yet allowing for considerable expansion of the springs
during the dispensing thereby accounting for the considerable total
thickness of the blades that are stored in the dispenser.
A further object of the present invention is to provide for a
dispenser including a minimum number of easily assembled parts
which are so arranged to cooperate with each other to rigidify and
strengthen the package thereby allowing for the provision of a used
blade storage compartment without deleteriously affecting the
strength of the dispenser or increasing the size thereof.
Yet another object of this invention is to provide a storage
receptacle for used blades thereby eliminating the need for
wrapping the blades for safe disposal. The storage receptacle is
adapted to permit automatic ejection and reception of the used
blades.
These, together with the various ancillary objects and features of
the present invention, which will become apparent as the following
description proceeds, are attained by this razor blade dispenser, a
preferred embodiment of which is illustrated in the accompanying
drawing, by way of example only, wherein:
FIG. 1 is a side elevational view of a blade dispenser constructed
in accordance with the concepts of the present invention, with
portions thereof being broken away to show the interior
construction, and illustrating the manner in which a blade is
automatically dispensed to a razor;
FIG. 2 is a plan view of the invention with the top thereof being
broken away to show the interior construction of this blade
dispenser;
FIG. 3 is a partial bottom plan view of the invention showing the
slot for receiving used blades; and,
FIG. 4 is a vertical sectional detail view taken along the plane of
line 4--4 in FIG. 3 illustrating the manner in which a used blade
is automatically ejected into the used blade receptacle.
With continuing reference to the accompanying drawing, wherein like
reference numerals designate similar parts throughout the various
views, reference numeral 10 generally designates a blade dispenser
having blades 12 therein having a body of suitable plastic
material, having a strip of metal 14 having a cutting edge bonded
therein. The razor, generally indicated at 16, is designed to
automatically retract the blade 12 from the dispenser 10 and may be
of a type similar to that disclosed in U.S. Pat. No. 3,388,831. The
blade 12 is held in place by the articular construction of the
razor 16 and is automatically ejected after sufficient use from the
razor 16 upon actuating of a finger actuating button 18 or the like
which ejects the blade 12 by spring action with considerable
force.
The dispenser 10 includes a housing 20 formed of two major parts
including a body 22 and a base 24. The base 24 is provided with a
peripheral flange 26 and includes a bottom 28 provided with a slot
30 therein into which used blades may be ejected from the razor in
the manner as shown in FIG. 4.
The body 22 includes a top 32, side walls 34 and 36, a rear end
wall 38, and a front end wall 40 which has an enlarged opening 42
therein in alignment with an opening 44 in the top 32.
A rib 46 is integrally formed with the base 24 and is in alignment
with a rib 48 on the top 32. The side walls 34 and 36 include pairs
of ribs 50, 52 and 54, 56 respectively, the ribs 50 and 54 being in
alignment with the ribs 46 and 48. A partition 58 is inserted
between the ribs 50, 52 and 54, 56 and is bonded thereto and is
bonded to the side walls 34, 36 as well as to the ribs 46 and 48 of
the respective base 24 and top 32. The partition bears against the
ribs 46 and 48.
The side walls 34 and 36 are provided with racks 59 and 60. A
platen 62 is provided which extends between the side walls 34 and
36 and includes rearwardly extending arms 64 and 66 carrying
detents 68 and 70 adapted to seat in the grooves of the racks 59
and 60. Integrally formed with the partition 58 are a pair of
truncated conical studs 72 and 74 which are arranged in opposed
relationship to studs 76 and 78 integrally formed with the platen
62. A pair of double volute springs 80 and 82 are received over the
studs 72, 76, and 74, 78 respectively and bias the platen 62 toward
the openings 42, 44 pressing upon blades 12 and directing them into
abutting engagement with the front wall 40. The use of the double
volute springs 80 permits for the use of springs having
considerable strength and a considerable range of expansion and
compression.
The rear wall 38 has a baffle 90 integrally formed therewith so
that when a blade 12 after use is ejected by pressing down on the
button 18, the used blade 12 will be directed into the used blade
receptacle 92 through slot 30 and kept by partition 58 from
entering into the magazine or blade delivery compartment 94 of the
dispenser. The baffle 90 will thereafter prevent alignment with
slot 30 and thus the used blades cannot fall out of the used blade
receptacle 92.
In use, successive withdrawal of the blades 12 in the manner shown
in FIG. 1 through use of the razor 16 is accomplished. Thereafter,
the used blades 12 may be discharged into the used blade receptacle
18 providing a convenient repository for the used blades since such
blades are of a size where they cannot fit in the conventional
used-blade receptacles heretofore provided in medicine cabinets and
the like in the home, hotels, motels, and the like.
Further, by providing a repository for the used blades in which the
blades can be automatically ejected, accidental injury to the user
because of bouncing or rebounding of the used blades 12 is
eliminated.
A latitude of modification, substitution and change is intended in
the foregoing disclosure, and in some instances, some features of
the present invention may be employed without a corresponding use
of other features.
