The present invention relates to the field of shaving razor dispensers and more particularly to the field of multiple razor cartridge dispensers for dispensing unused razor cartridges and retaining used razor cartridges.
Shaving razors have evolved over the years from a straight edge razor, having a razor edge that needed to be sharpened from time to time, to a safety razor having a unitary handle and head, the head being opened to receive replaceable blades, to a handle and razor cartridge system, where a razor cartridge having integrated blades further included a connection mechanism to attach the cartridge to a handle.
With the advent of replaceable blades, there next came the need to keep a store of razor blades for replacement when used blades lost their edge. With safety razors, which used substantially flat single or double edge blades, new blades were individually wrapped in paper, stacked and placed in a cardboard box with end flaps for removing a wrapped blade. The flat nature of the safety razor blades made wrapping in paper and storage of a number of wrapped blades in a small cardboard box very easy.
However, once disposable razor blade cartridges came into use, there was a need to store the blade cartridges in a dispenser where the cartridge could be attached to or removed from the handle quickly and easily. These dispensers were most often formed of plastic and provided separate compartments for individual blade cartridges.
One example of a cartridge dispenser is found in U.S. Pat. No. 3,835,532, which shows a number of compartments into which individual blade cartridges are stored, having latches to maintain the cartridges in the compartments. When a blade cartridge is to be used from the dispenser, the user attaches the handle to the blade cartridge and pulls up on the handle to overcome the force of the latch on the blade cartridge, releasing the blade cartridge from the dispenser. The user can replace a used cartridge into the dispenser by pushing the used blade cartridge into an empty compartment, overcoming the force of the latch when pushing down, and then releasing the cartridge from the handle.
Blade cartridge dispensers have changed with changes in blade cartridges. For example, blade cartridges have changed to include not just the blade portion but also a connection portion that is pivotably attached to the blade portion. In keeping, the dispensers have been designed to include an area for the connection portion of the cartridge.
As shown in U.S. Pat. No. 6,041,926, blade cartridge dispensers have been described to include two piece structures that form compartments for containing the connection portions as well as the blade portions of the cartridge. The structure shown in U.S. Pat. No. 6,041,926 also describes a latch that engages the top of the connection portion of the cartridge, with a cam on the handle to unlatch the connection portion and remove the cartridge.
However, there is needed a razor cartridge dispenser which simply and stylishly retains, dispenses and accepts razor cartridges that is easily made and contains its own packaging.
The present invention is directed to a razor cartridge dispenser for retaining and dispensing razor cartridges having a blade portion pivotably mounted to a connection portion, the connection portion including a mechanism for connecting the razor cartridge to a handle, the dispenser comprising:
a. a unitarily molded member for retaining, dispensing and accepting a plurality of individual razor cartridges, the molded member comprising a compartment for each of the individual razor cartridges in sequence, with each compartment comprising:
b. a package member providing a covering for the molded member, the package member comprising a reclosable flap for providing access to the razor cartridges in the compartments of the molded member.
In the preferred embodiment, the flexible arm on which the latch is located extends along the top wall of the blade portion cavity on an axis from the closed side wall to the open side wall, avoiding unintended removal of the cartridges from the compartments. When the cartridge is intended to be removed from the compartment, a handle is connected to a connection portion of the cartridge and the cartridge is slid laterally out of the compartment through the open side walls of the blade portion and connection portion cavities.
Similarly, when a used cartridge is intended to be replaced into an empty compartment, the cartridge is slid laterally into the compartment through the open side walls of the blade portion and connection portion cavities, followed by release of the cartridge from the handle.
The blade portion and connection portion cavities are preferably sized so as to permit entry and removal of the blade cartridges only through the open side walls of the blade portion and connection portion cavities. This may include the use of detents on one or more of the walls of the blade portion cavity and/or connection portion cavity for providing closer tolerances between the dimensions of the cartridge and the dimensions of the compartment as well as ease of insertion and removal of the cartridges into and from the compartments.
To assist the user with the insertion into and removal from the compartments through the open side walls of the blade portion and connection portion cavities, it is preferred that the top opening of the connection portion cavity not extend the full width of the blade portion of the cavity. More specifically, the top opening of the connection portion cavity preferably does not expose the entire width of the blade cartridge when the blade cartridge is fully inserted into the compartment.
The unitary molded member preferably further comprises a left side wall, a right side wall and a rear wall defining an upper perimeter about three sides of the unitarily molded member. It is preferred that the upper perimeter is just sufficient in height to extend above the uppermost elevation of the connection portions of the cartridges in the compartments. Moreover, the left, right and rear walls preferably form a frame for the package member, ensuring that the connection portions of the cartridges are properly fitted within the package member.
The package member preferably encloses the top, bottom front and back of the molded member with cartridges in the compartments while providing reclosable access thereto. Most preferably the package member is formed of a heavy stock paper or cardboard, however, it can be formed of plastic or coated materials as desired by the designer or manufacturer.
The package flap of the package member preferably includes at least a portion of a back of the package member, a top of the package member and at least a portion of a front of the package member. In its most preferred embodiment, the package flap includes side corners to maintain the top and the at least a portion of the front at a substantially right angle.
In keeping, the razor cartridge dispenser of the present invention preferably provides a package member which can be opened, closed and reopened to insert used blades into or remove new blades from the compartments of a molded member entirely contained within the package member. A catch comprising cooperating catch elements is preferably provided to maintain the dispenser in a closed configuration when desired. When closed, the preferred package member does not show the molded portion or the blade cartridges contained therein.
The present invention will be better understood when considered in view of the attached drawings, in which like reference characters indicate like parts. The drawings, however, are presented merely to illustrate the preferred embodiment of the invention without limiting the invention in any manner whatsoever.
As shown in the drawings, and particularly
