ORNICY BLADE DISPENSER 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 US. Pat. to Fishbein, No. 3,071,856, issued Jan. 8, 1963, entitled Razor Blade and Method of Making Same and the US. Pat. to I-Iansom, 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 suchas stainless steel, chromium alloy, or the like, which may have a coating such as that disclosed in US. Pat. No. 3,07l,856. These blades are mounted in a magazinetype dispenser for sequential dispensing and, as disclosed in US. 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 US. Pat. No. 3,388,831. The blade 12 is held in place by the articular construction of the razor l6 and is automatically ejected after sufi'lcient 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 fonned 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 walls34 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. j

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.

in opposed relationship to studs 76 and 78 integrally 1 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 intothe 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. I 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.
