a -;'The present invention has reference to a novel form of container designed primarily for containing razorblades of a well known type, the container being so constructed that 1 5 it may be readily and easily converted into a jknife byutilizing one ofithe razor blades 7 from the container, asthe knife blade.

An important objectof the inventionis toprovi'de a container of this character'in- 1Q eluding a removable blade carrying member -in one end thereof, the blade being held in the 8 blade carrying member by frictional contact therewith so that when pressure is di rected to the free end of the blade,,the blade will be forcedthrough the'blade carrying f member and into the container; "A still furtherobject of the invention is the provision of a container of the character thatimay be manufacturedat such a low cost 'fZOthat the container maybe distributed to througha container showing a blade as posi- Figure 3 is a perspective view of the removable blade holding end member. 7 Figure ,4: is alongitudinal sectional view illustrating a modified form of the invention. F igure, 5 is a perspective viewof the re fmova'ble bladeholding end member. Referring tojthe drawing in detail, the

container is indicatedgenerally by the refer,-

ence character 5 and is'preferably formed. of

I sheet metal so that it may be readily and easily constructed by a single operation of a j stamping machine. v v a As shown, the casing is tubular in formaformed of sheet metal ing member container, which also tapers slightly, a bindup between the i blade the back of the blade tion; and the tapered ends thereof are proended-with threads 6, the threads at one end of the container being designed to receive or cooperate with the threads 7 of the remov-.

able blade supporting member 8 to secure ,the blade supporting member in one'end of thecontainer 5. a

This blade supporting member is also tremities tapering from the central portion thereof, to theend thatas theblade support 8 is positioned in one end of'the ing action will be set holding member 8 and container, causing the blade holding member to firmly grip the blade, which is indicated at 9, and which has one of its ends positioned in the blade supporting member.

substantially tubular information, the same is split throughout its length, the ends thereof being extended inwardly defining flanges While the blade pp g member 8 is and has tapered ex- 10 which in practice engage the sides of the,

blade to hold it against movement. To fur ther insure against movement of the blade when positioned in the blade holding member 8, agroove 11 is provided within which rests, as shown byv Figure l. 'The reference character 12 designates a removable closure for closing one end of the container 5 and affords means whereby the blades contained within the member 5 and which have been discarded as razor blades,

may be removed or replaced.

The cap 13 which is shown in Figure 1 as positioned over one end of the container, is primarily designed as a tioned over the blade 9 in use, it being understood that the formation of the threads of the container is such as to permit the cap to be readily positioned.

As shown by Figure 4 of the drawing, the container which is indicated by the reference character 14 is also tubular in formation, one

end thereof being closed as at 15, the opposite end being closed by the blade holder 16. Blade engaging flanges 17 form a part of.

the blade holder 16 and securely grip the guard cap to be posiwhen the device is not blade positioned therebetween, when the blade holder is forced into the open end ofthe container 14. The blade holder 16 also tapers towards its ends so that when forced into the open end of the container 14, the

sides of the holder will be contracted to accomplish the purpose of the invention.

From the foregoing it Will be obvious that the container prov'idesnot only a receptacleto receive discarded razor blades, but affords a convenient handle, shouldit be desired to position one of the blades in one end ofthe handle, to use the device as a knife, for cutting the finger nails, trimming pencils or similar uses;

I- claim:

' A'combined'blade containerand knife in "eluding a tubular'body, portion having a tapered open end, aholder embodying a tubular membersplit along itsside, portions of o the blade holder adjacent to the split being extending inwardly defining Wide blade engaging flanges, a blade positioned Withinfthe blade holder between the flanges, and said flanges adapted to grip .the blade When the blade holder is forced into'the tapered end of the tubularbody portion.
