1 Claim. (CI. 30-90) ABSTRACT OF Tim DISCLOSURE l'lTlie T-shaped head of a razor equipped with 'a band blade'is protected by a removable, flexible plastic cover. The 'cover is generally rectangular, the bottom side being provided with a rectangular opening which is as wide as the "cover, but not quite as long, one end of the bottom side being covered over to form a pocket. When the cover is placed on to a' razor, one end of the head of the razor is slipped into the pocket at this end of the opening, and then the rest of the end of the razor is snapped into the opening. The cover fits snugly on the head of the razor. The covered end of the head tends to prevent unwanted dislodgement of the cover from the end of the razor.
The invention relates to the combination of (1) a razor equipped with a band blade and (2) a removable flexible plastic cover which covers and protects the head of the razor in which the band blade is located. There are two razors with band blades currently on the market, one being manufactured by Gillette Safety Razor Company, a division of The Gillette Company of Boston, Mass. known as their Techmatic razor, and the other being manufactured by Schick Safety Razor Company, a division of Eversharp, Inc., of Milford, Conn., and known as Schick band r'azor.
These razors are T-shaped. A removable and replaceable cartridge fits into the upper part of the T, forming a large part of the crossbar and extending down into the handle or stem of the T. A band blade is located in the cartridge. The different makes of razors employ different means for holding the cartridge in place, and for winding the blade.
The bottoms of the ends of the T-crossbar or head slant upward and outward from the handle so that the ends of the head are vertically thinner than the portions adjacent the handle. The head comprises a guard which covers the back of the head and extends forward over the head, covering substantially all of it except for the front edge. The back portion of the top surface of the guard is substantially perpendicular to the handle, and the front portion slopes slightly toward the front of the head into close proximity to the exposed portion of the blade.
The cartridge which contains the continuous shaving band is almost as thick as the handle, and fits flat against the metal member which supports the guard from the portion of the handle below the cartridge. The bottom end of the cartridge fits flush against the end of this portion of the handle and its top fits under the guard. It snaps in place and is held in place by a lock.
The plastic cover forms a snug fit over the head of the razor. It is advantageously made by dipping a suitable form in a vinyl plastisol or other suitable plastic. It covers the top of the crossbar or head of the razor and extends down over all four sides of the head and in under one end. When removed from the razor, it will be seen that the cover is an open plastic shell of substantially uniform thickness. Its top covers the guard which extends over the head of the razor, and three of its walls cover the back, front and one end of the head. The

other end of the cover is formed as a pocket, The bottom of the cover is open and the opening is substantiallythe same width as its top. One end of the opening is covered to form the pocket. In placing a cover over the head of a razor, the pocket is first slipped over one end of the razor head, and then the rest of the cover is pressed into place over the opposite end of the razor head, The cover formsa relatively snug fit with the head, and the covered end assists in preventing unwanted removal o the cover from the razor head. I p Q 7 i The invention is further described in connection ivith the drawings, in which v FIGURE 1 is 'a view in perspectiveofthecove-red head of one of the razors using a band blade which is now on the market;
FIGURE 2 is a top view of the cover; 1
FIGURES 3 and 4 are views of the opposite ends of the cover, on lines -3-3 and 44 of FIGURE-2y I FIGURE 5 is a back view of the covered razor head;
FIGURE 6 is a bottom view of the cover which clearly shows the opening;
FIGURE 7 is a section on the line 8-8 of FIGURE 7;
FIGURE 8 is a side view of the razor shown in FIG- URE 1 with the cover shown in section; and
FIGURE 9 is a similar view of the other razor now on the market which uses a band blade, with the same cover shown in section.
The razor comprises the handle 5, the removable cartridge 6, and a metal plate 7 which is fastened to the handle 5 and terminates in the guard 9 (FIGURE 8). The cartridge is held in place by catch 10. Lever 11 is swivelly mounted on the back of the plate 7, and is turned in the direction of the arrow (FIGURE 1) to advance the shaving band in the cartridge to provide a fresh edge over the head of the razor under the guard.
The base of the cartridge fits between the flat upper end of handle 5 and the forwardly and downwardly extending front portion 12 of the top of the guard (FIG- URE 8). As shown in FIGURE 8, the rear of the head of the razor is perpendicular to the handle, and the forward portion 10 slopes slightly toward the front of the head into close proximity with the band blade 13 which projects forward. In FIGURES 8 and 9 the band blades are shown coming up out of the cartridges and are bent to lie flat against the top of the cartridges so that only their front edges are exposed.
The back wall 14 of the cover 15 shown in the drawings, which is tailored to quite exactly fit the razor heads, is not perpendicular to the top 16 of the cover (FIGURE 8), but slopes inwardly, and the front wall 17 is almost perpendicular but slants outwardly at a smaller angle than the back wall slants inwardly. Thus, the walls tend to grip the razor head. The back wall 14 is somewhat taller than the front wall 17. However, a cover with front and back walls of the same height and perpendicular to the top may be used, but not as satisfactorily for the razors of this type now on the market as a cover of the shape shown in the drawings.
The opening 20 in the bottom of the cover is only slightly narrower than the head of the razor. The back and front walls 14 and 17 and one end wall 18 (FIGURE 6) define edges of the opening. This opening extends from the wall 18 past the middle of the razor head. The opposite end of the cover is covered at 19 so that at this end of the cover there is a pocket 22 (FIGURE 7) which form a snug fit around one end of the razor head.
In placing the cover on a razor head, the pocket 22 is first slipped over the end 22 of the head, and then the other end of the head is snapped into the cover. Although not necessary, it is desirable to have the taller back wall 15 at the back of the razor head. In removing the cover,
tfi reverse proceilu'reisfollov'ved, the covered end 22 of thew oye s,hq aslhqladtt e. remov d t Qm h razor head.
Although the other razor .on the market which has a band bladeispf adifierent design, the shape and dimensions. of-the head are quite similar, and the same cover 15 fits both razorsfequally well. The use of this cover 15 on this other razor is illustrated in FIGURE 9. The front 30 of the guard dips down to' close the band blade 31 held in crittridgefiZQTh'efrnetal plate 35extends from the guard, across the back of the cartridge 32 to the handle.36 to which it is fastened. The cartridge is held invplace by catch 37. Theblade is advanced by lever 38. The heads of the razors are so nearly the same dimensions that the same cover..can be usedinterchangeably on bothrazor heads. I .The, invent-ion is covered in the claim which follows.
