CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/026,960, filed Jul. 21, 2014, which is herewith incorporated herein by reference, in its entirety.

FIELD OF THE INVENTION

The present invention relates generally to the field of cases and protector for safety razors, and more particularly to devices and methods for extending the useful life of the blades of a safety razor.

BACKGROUND OF THE INVENTION

Safety razors, in the form of disposable razors and razors with replaceable disposable blade attachments remain very popular for daily shaving use.

In use of safety razors, the useful life of the blades of a safety razor is significant, as it can be cost prohibitive to replace disposable blade attachments or disposable razor on a frequent basis.

As a consequence of the high cost of frequent replacement, many methods and devices for extending the useful life of disposable razors and blade attachment have been proposed in the past.

Such past methods, systems, and devices, include:

    • a) Drying of the blade/blades after use;
    • b) Storing the razor outside of humid areas, such as bathrooms;
    • c) Storing the blade/blades in a cup, jar, or drinking glass with mineral oil or alcohol;
    • d) Applying a lubricant of some kind with a cotton swab, Q-Tip; and/or
    • e) “Dry shaving”, without the use of water or shaving foam at all.

Cases for safety razors are available, but most are merely plastic containers for storage, which do not provide any function to protect the razor blades from oxidation and other degradation, which causes the blades to become dull.

Additionally, there are containers and cases for submerging or partially submerging a razor in different solutions to prevent oxidation, but most require the ongoing purchase of special liquid solutions from the manufacturer, and may not be convenient to use or transport, due to risk of spillage.

As such, considering the foregoing, it may be appreciated that there continues to be a need for novel and improved devices and methods for extending the useful life of safety razors.

In a related embodiment, as shown in FIG. 7, which illustrates a cross sectional view of a lubricating pad 700, which can be a right or left lubricating pad 142 144, which can include:

    • a) a soft foam inner core 702;
    • b) an outer core 704, which is configured such that the inner core 702 is sandwiched between an upper layer 744 and a lower layer 742 of the outer core 704; and
    • c) an outer cover 706, which is configured such that the outer cover covers both the outer core 704 and the inner core 702.

In an alternative embodiment, the outer core 704 can be configured such that it entirely covers the inner core 702;

In a further related embodiment, the soft foam inner core 702 can have a thickness of approximately 0.5 inches, and can be made from a polyurethane foam, and serves the purpose of allowing a gentle compression formed recess upon enclosing a razor head 302 inside the razor storage device 100. The polyurethane foam can for example be an expanded or extruded, open-cell or closed-cell, flexible polyurethane foam. In general, the soft foam inner core 702 can be made of soft foam material, such as softer versions of upholstery foams.

In a further related embodiment, the outer core 704 can be made of a polypropylene fabric, and can for example be configured as a layer of 4, 8, 12, 16, 20, 24, or 28 polypropylene fabric sheets, which are water resistant and oil absorbing, such that the outer core 704 functions as a primary reservoir for the lubricating oil. Such polypropylene fabrics are commonly used for oil spill clean-up in waterways and at sea, as well as for spills occurring on land and in buildings, since they will not retain water, but can absorb large quantities of oil relative to volume and weight of the polypropylene fabric. The number of layers of polypropylene fabric can vary, such that there can be only one layer, or a large number of layers, including over 28 layers, depending on application, and the specific type of polypropylene fabric.

Some examples of polypropylene fabric sheets for use in the outer core 704 include:

    • a) PIG™ Oil-Only Absorbent Mat Pad, manufactured by New Pig Corporation;
    • b) WY-JH03 oil absorbent roll, and universal spill laminate fabric manufactured by Jiahe™; and
    • c) YL-PPO melt-blown oil absorbent fabric manufactured by Yuli™.

In a further related embodiment, the outer cover 706 can be made of a microfiber fabric, including a microfiber polyester and/or polyamide fabric. The outer cover 706 can be sewn together around the outer and inner cores 702 704, or it can be heat bonded together, according to well-known industrial methods.

In related embodiments, the upper and lower lubricating pads 144 142 can be configured to match the shape and size of respectively the upper and lower interior cavities 222 212.

In a related embodiment, the upper and lower lubricating pads 144 142 can be identical, of similar shape, size, and composition.

In a related embodiment, parts of or all of the upper and lower lubricating pads 144 142 can be antimicrobial, for example via treatment with an antimicrobial agent, or via construction from materials that are inherently antimicrobial. This can include treatment with or use of various well-known agents or materials with antibiotic and/or antifungal properties.

In a further related embodiment, the soft foam inner core 702, the outer core 704; and/or the outer cover 706 can be treated with an antimicrobial agent.

In a further related embodiment, the lubricating oil can be treated with an antimicrobial agent, or include an inherently antimicrobial property.

In a related embodiment, the upper and lower lubricating pads 144 142, when impregnated with lubricating oil, function in a manner similar to an ink-pad, such that they can discharge a thin layer of lubricating oil onto a safety razor's 300 blade/blades, when the razor head 302 is gently pushed into the surface of either the upper or lower lubricating pad 144 142, and discharge a thin layer of the lubricating oil onto the blade/blades, for example with a gentle slight pull down of the safety razor 300 handle 304, when the safety razor 300 is inside the razor storage device 100 in a closed configuration.

In a related embodiment, no seals are provided, nor necessary for the purpose of containing the lubricating oil within the confines of the razor storage device 100, as the correct measured amount of lubricating oil applied to the lubricating pads 142 144 is substantially less than the lubricating pads 142 144 are capable of absorbing. This allows for the razor storage device 100 in a closed configuration to be stored when in virtually any position, without leakage of the lubricating oil.

In a related embodiment of a process or method of using the razor storage device 100, after a user has shaved with and then rinsed the safety razor 300, the safety razor 300 need only be blotted on a towel and the blade/blades then nested upon the oiled pad contained within the razor storage device 100, and the case closed. At this point the shaving portion, i.e. head 302, of the safety razor 300 is gently depressed between the upper and lower lubricating pads 144 142, such that the blade/blades are coated with a very thin film of oil. Hereafter, the user may wish to replace the manufacturer's plastic safety clip over the razors head 302, or choose to leave the safety razor 300 inside the case/container, which holds the oil absorbing pads until its next use.

Here has thus been described a multitude of embodiments of the razor storage device 100, and methods related thereto, which can be employed in numerous modes of usage.

The many features and advantages of the invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention, which fall within the true spirit and scope of the invention.

Many such alternative configurations are readily apparent, and should be considered fully included in this specification and the claims appended hereto. Accordingly, since numerous modifications and variations will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and thus, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
