FIGS 9m: RUSSELL (flax ATTORNEY United States Patent 3,408,737 SAFETY RAZOR COVER Frank W. Steer-e, Jr., Akron, and John R. Russell,

Cuyahoga Falls, Ohio, assignors to Steere Enterprises Inc., Tallmadge, Ohio, a corporation of Ohio Filed Aug. 1, 1966, Ser. No. 569,148 1 Claim. (CI. 30-90) ABSTRACT OF THE DISCLOSURE the cover by the shaver in slipping the cover on and off of the razor head.

This invention relates to a resilient elastomeric cover for the T-type head of a razor. It is intended more particularly for the head of a Gillette-type razor in which both edges of a blade are exposed although it may be made for the head of a razor in which only one edge of the blade is exposed.

The cover is advantageously molded or dip molded from a vinyl or other resilient plastic composition. It includes a front face, usually imperforate, which covers the end face of the razor head. The back face of the cover includes a central opening to accommodate the handle of the razor, and this opening is continued to the end of the back face to provide for the handle as the cover is slid over the razor head and removed from it. This opening is preferably restricted at one place so as to engage the handle of the razor and prevent the separation of the cover from it. The end of the cover is open so that the cover can be slipped over the head of the razor. Usually, atthis open end of the cover a narrow lip extends backward from the front face of the cover to partially enclose an end of the head of the razor when the cover is in use. Retention of the razor head in the cover may depend entirely upon a restriction of the opening in the cover about the handle, or it may depend entirely upon such a backwardly extending lip or other suitable means.

The outer surface of the edges of the cover which cover the slots in the razor head through which the edges of the blade protrude, are irregular and preferably not parallel. They include at least one lateral bulge and preferably there is a centrally located depression on each side of the cover between two such laterial bulges. The reason for this is to prevent the fingers of the user from slipping off of the cover against the sharp blade edges in an attempt to slip the cover over the razor head. They similarly prevent his fingers from slipping when the cover is slipped off the razor head.

The invention is further explained in connection with the accompanying drawing, which pertains more particularly to a cover for the head of a razor. In the drawings- FIGURE 1 is a view of the back cover in use (partly broken away), with a razor shown in phantom;

FIGURE 2 is a view of the cover from the front, at an angle;

FIGURE 3 is back view of the cover;

FIGURE 4 is a view on the line 4-4 of FIGURE 2;

FIGURE 5 is a view on the line 5-5 of FIGURE 4; and

3,408,737 Patented Nov. 5, 1968 ice FIGURE 6 is a view on the line 6-6 of FIGURE 2.

The razor shown in FIGURE 1 comprises the handle 5 and the head which includes the head plate 6 which is divided clown its middle, both halves being hinged to press a blade 7 toward the back plate 8 of the head and hold it there.

The back 12 of the cover is open at one end. The opening tapers along V-edges 13 to a central opening 14, and the edges 15 of this central opening converge toward the edges 13 to form a restriction just wide enough to engage the handle of the razor. The V-edges 13 may extend further toward the opening 14, and the opening may even be circular in outline except for the opening where the edges 13 open into it. The front 20 is imperforate. It could be perforate to help drying, if desired.

One end 25 of the cover is closed and the other end is open at 27 and joins the V-opening provided by the edges 13. The lip 28 which extends backwardly from the front 20 of the cover, partially closes the opening 27 and tends to keep the cover from slipping off of the razor head.

The edges each bulge adjacent their respective ends to form the bulges 30, 31, 32 and 33 with the depressions 35 and 36 in the edges between the bulges. The cover material is sufiiciently stiff so that the bulges and depression tend to retain their shape although the cover is flexible so that it gives as the head slips into the opening 14 in the back of the cover, and as it slips over the lip 28. The depressions assist in slipping the cover over the head of the razor and tend to prevent the users fingers from slipping off of the cover on to the sharp edges of the blade. They also assist in removal of the cover from the razor head by preventing the fingers from slipping from the cover, although in this operation there is no danger of their contacting the razor blade.

The invention is covered in the claims which follow.

We claim:

1. A seamless, resilient, elastomeric cover for the T-head of a razor which has an opening at one end which extends to the middle in one face of the cover to accommodate the handle of the razor as the cover is slid longitudinally on and off of the head, which opening in the face of the cover is restricted to a width just wide enough to engage the handle of the razor when located at the restriction, the width of the cover being nonuniform with a wider portion adjacent each end of the cover and a depression in the elastomer of the cover in each side of the cover between said two wider portions to improve engagement by the user in slipping the cover over the razor head and slipping it off of the razor head, each edge of the cover being continuous.
