FIG. 3

INVENTORS WILFRED HAROLD MKEE JAMES GORDON STEELE ATTORNEYS 3,069,055 ROLL TAPE DISPENSER AND CONTAINER James Gordon Steele and Wilfred Harold McKee, London, Ontario, Canada, assignors to Kemp Products Limited, London, Ontario, Canada Filed Dec. 16, 1960, Ser. No. 76,262 4 Claims. (Cl. 225-47) This invention relates to roll tape dispensers and containers and, in particular, to a roll tape dispenser and container manufactured of a mouldable material such as plastic.

The tape dispenser and sealed container in accord with this invention is intended for dispensing tape and protecting tape from atmospheric conditions, moisture, dirt and dust as distinct from a dispenser which affords little or no protection for the tape. The need for the type of dispenser disclosed herein has long been recognized but could not previously be made at a competitive price due to certain manufacturing difficulties Every type of tape dispenser provides some sort of axle means to hold a roll of tape for rotation and some sort of severing means for tearing off the tape as required. It was found, however, that certain manufacturing difliculties were encountered when attempting to provide these two essential elements in a moulded article, particularly so when also attempting to provide a top for the container which would seal the dispenser when in place.

The above mentioned manufacturing difiiculties pertain to the problem of properly orienting and locating the severing mechanism so that it performs its function satisfactorily while, at the same time, avoids interfering with the function of the top, i.e., to seal the container.

The method of manufacture in accord with this invention overcomes the difficulties above mentioned and pro vides a roll tape dispenser and container capable of performing the normal functions of this type of device while, at the same time, being capable of tight closure as to protect the tape to be dispensed.

It is an object of this invention to provide a roll tape dispenser and container manufactured of a mould-able material, such as mouldable plastic.

It is a further object of this invention to provide aroll tape dispenser and container having a press fitted top capable of sealing the container as to protect the roll tape to be dispensed.

It is a further object of the invention to provide a method of manufacturing a roll tape dispenser and container in accord with this invention.

In the drawings:

FIGURE 1 is an exploded perspective view of a roll tape dispenser in accord with this invention.

FIGURE 2 is a side elevation view of the roll tape dispenser illustrated in FIGURE 1 showing a roll of tape within the dispenser, and,

FIGURE 3 is a vertical cross section taken along the line 3-3 in FIGURE 2.

Referring now to FIGURE 1, the illustrated embodiment of the tape dispenser in accord with this invention essentially consists of a receptacle-like bottom member 10, a top member 14 and a frame member 11 carrying a roll tape mounting unit 12 and a tape severing mechanism 13.

Frame member 11 is adapted to fit on the upper edge 'United States Patent 3,069,055 Patented Dec. 18, 1962 of bottom member 10 and top member 14 is, in turn, adapted to fit over frame 11. It is the principle of moulding roll mounting unit 12 and severing mechanism 13 separately from the bottom member 10 which chiefly characterizes this invention.

If roll mounting unit 12 and severing mechanism 13 were moulded integrally with the bottom member 10, it would be impossible to extract the unit thus formed from the mould. This is because the severing mechanism 13 would extend across the open top of bottom member 10, and would thus prevent the withdrawal of the inner mould. On the other hand, if the severing mechanism were moulded along the upper edge of one end of bottom member 10, the severing mechanism would then interfere with the sealing engagement between bottom member 10 and top member 14. In this regard, it will be noted that if the sealing engagement between the top and bottom members is to be effected by a press fit of top member 14 over the upper free edge of bottom member 10, the said upper free edge must have a smooth face over its full length and the formation of a severing mechanism as part of said edge would not achieve this result.

Instead of moulding the severing mechanism 13 to bottom member 10 with the attendant disadvantages above noted, this invention moulds the severing mechanism and the roll tape holder integrally with the secondary frame 11 which is then fixed to the upper free edge of bottom member 10 as by plastic welding or by means of an adhesive or the like. Bottom member 10 may be then easily moulded as may the frame member 11 and the top member 14.

It will be noted that the upper free edge of bottom member 10 is somewhat reduced in thickness. Frame member 11 is provided with a corresponding peripheral slot 15 so that frame member 11 actually caps the upper edge of bottom member 10 as can best be seen in FIG URE 3.

Roll tape mounting unit 12 consists of a pair of 0pposed journal-like members having circular projections 16 on their inside surfaces for loose engagement within the core of a roll of tape. Severing mechanism 13 is, of course, provided with a toothed forward edge to effect the tearing of the tape.

Top member 14 is preferably formed of a transparent plastic and is shaped to press fit over the outside of frame 11 as to tightly seal the container.

What we claim as our invention is:

l. A moulded roll tape dispenser and container comprising a receptacle-like bottom member having an open top; frame means fixed to said bottom member and encompassing said open top, a pair of opposed inwardly projecting journal members for mounting a roll of tape for rotation carried by said frame means, means for severing tape also carried by said frame means and extending across said open top, and lid means press fitted over said frame means as to close the container when in place and to expose a roll of tape carried by the dispenser when removed.

2. A roll tape dispenser and container as claimed in claim 1 in which said frame means, said severing means and said means for mounting a roll of tape are moulded as an integral unit.

3. A roll tape dispenser and container as claimed in claim 2 in which said frame means is fixed to said bottom means by an adhesive.

4. A moulded plastic roll tape dispenser and container comprising an elongated box-like bottom member having an open top, an elongated rectangular frame press fitted over and glued to the upper edge of said bottom member as to encompass said open top, said frame carrying a roll tape mounting device comprising a pair of opposed inwardly projecting journal members for holding a roll of tape for rotation by engaging the core of said roll of tape at either end thereof, said frame also carrying a toothed tape severing mechanism extending between the sides of said frame and thus extending across said open top, and a removable lid press fitted over said frame to seal the dispenser when in place and to expose said roll of tape for user when removed.
