Petitto, Harrison, Mesa, assignor to Foster Grant Co., inn, Leorninster, Mass, a corporation of Belaware Filed Aug. 1%, i963, Ser. No. 3%,557 11 Claims. (ill. 22566) This invention relates to a dispensing apparatus; and more particularly to tape dispensers having easily re movable bearing spools to support the tape rolls.
The invention is especially adapted for use in an environment wherein several different types of rolled material may be used. The invention comprehends the use of removable bearing spools on single or multiple roll dispensers so as to adapt the dispensers for interchangeable rolls, and provide them with a means to allow refills to be inserted easily and quickly. While the preferred embodiment is disclosed as a tape. dispenser, it will be apparent that the device may be used in conjunction with any type of rolled material such as string, packaging ribbon, film and the like. The bearing spools can be furnished as part of the dispenser, or they may be inserted in each roll of tape to be discarded when the tape or the like is used up.
One object of the invention is to provide a roll dispenser which can be easily and economically made.
Another object of the invention is to provide a tape dispenser which can be molded in one piece, and bearing spools therefor which can be quickly and easily inserted and removed.
Still another object of the invention is to provide a tape dispenser with easily removable bearing spools for the rolls of tape, so that the rolls of tape can be quickly and easily inserted and removed at will.
Still another object of the invention is to provide a removable deformable elastic bearing, said bearing being adapted to be quickly and easily locked in place and removed.
The foregoing and other objects are achieved by providing a tape dispenser made of a stiff elastic thermoplastic material such as high impact polystyrene, or nylon or polypropylene which may be easily molded into a body portion and a bearing spool by conventional molding operations such as injection molding machines. The body portion has a plurality of support projections adapted to support and removably lock bearing spools therebetween on the dispenser. The bearing spools have slots on the circumference thereof adapted to coact with notches in the support projections to lock the spools in place. The bearing spools, being made of elastic material, are inserted and removably by temporarily deforming them so that they may be moved into and out of locking engagement with the notches in the support projections.
By the above outlined apparatus, several advantages are obtained. An economical tape dispenser is provided. This dispenser has bearing spools which can be quickly and easily inserted and removed so that rolls of tape may be interchanged at will. This provides an economical dispenser which can be adapted to a variety of tapes and uses.
Other objects and features of the invention will become apparent by reference to the following specification and to the drawings.

The dispenser comprises a molded thermoplastic body portion 12 having spaced side walls 16, a front bridging member 18, and a rear bridging member 20 for holding the walls 16 in parallel spaced relationship. The front bridging member 18 also supports a serrated cutting edge 22 to aid in tearing the tape dispensed from the dispenser.
The side walls 16 are formed with front and rear support projections 24, 26 on the interior portions 28 thereof. These projections cooperate to form notches 30 delinated by the interior portions 28 of the side walls and the inner ends 32, 34 of the projections 24, 26. The interior portions 28 of the spaced walls define the edges of the notches, the rearwardly facing inner ends 32 of the front support projections 24 define the front ends of the notches, and the forwardly facing ends 34 of the rear support projections 26 define the rear ends of the notches 3ft.
The removable bearing spools 14 as well as the dispenser are molded from a stiff elastic thermoplastic material such as high impact polystyrene, nylon or polypropylene. Each bearing spool is presently formed of a hollow cylinder having an internal surface as and an external surface 38, and ends 39. The bearing spool 14 also has locking slots an formed in the external surface 38 thereof and extending axially along the external surface 33. These locking slots 4%) are adapted to mate with the inner ends 32, 34 of the support projections 24, 26 so as to removably lock the bearing spools 14 in place on dispenser body 12.
Operation vention is as follows. When a roll of tape 42 having a core 43 is to be inserted into the dispenser body 12, a bearing spool 41 is inserted into a roll of tape 42. The outer diameter of the bearing spool 14 is preferably smaller than the internal diameter of the core 43 of the tape roll 42 so that a loose fit is provided. The hearing spool is subsequently placed in position so that the locking slots on one side of the hearing are in engagement with either the forwardly or rearwardly facing inner ends 32, 34 of the support projections 24, 26. For purposes of example it will be assumed that the locking slots 4i on oneside of the bearing spool 14 have been placed in engagement with the forwardly facing inner ends 3 of projections 26 (see FIG. 5). Having done this, a force F is applied on the periphery of the roll of tape. The force F is preferably applied on the periphery of the roll of tape in the vicinity of t e top thereof, said force being applied in a downwardly direction (FlGS. 5 and 6). As the force F tends to move the roll of tape with the bearing spool and the locking slots downwardly toward the locked position, the rearwardly facing inner ends 32 of the front support projections act to earn the bearing spool into an elliptical-like shape (FIG. 6). This deforming of the elastic bearing spool allows it to be moved into position wherein the slots 49 in the periphery of the cylinder are aligned with the rearwardly facing inner ends 32 of the front projections 24. When the locking slots of the bearing spool and the inner ends 32 of the support projections 2d become aligned, the elasticity of the bearing spool causes it to spring outwardly, moving the locking slots at into engagement with the inner ends 32 of the front projections 24 (FIG. 4). The bearing spool 14 is now firmly locked in place, and the tape roll 42 is rotatably mounted thereon due to the loose fit between the spool 14 and the core 43 of the roll of tape 52. To dispense tape, the tape is pulled from the roll 4?. and
' torn across the serrated edge 22 when the desired length is attained.
When it is desired to remove a roll of tape or hearing spool, one merely has to press rearwardly with the thumb to again deform the bearing spool 14 so as to move the locking slots do out of engagement with the support pro jections 24 (FIG. 7) and subsequently move the deformed bearing spool upwardly or downwardly past the support projections 24, 2.6.
Modification of FIGS. 9-11 FIGS. 9-11 show a modification of the invention wherein the bearing spools 14 are utilized in a multiple roll dispenser 44.
In this modification, the side walls 45 are formed with front and rear support projections 38, 50 on the interior portions 52 thereof. These projections cooperate to form notches 54 delineated by the interior portions 52 of the side walls 4s and the inner ends ss, $3 of the projections 48, 5G. The interior portions 52 of the spaced walls 46 define the edges of the notches 54, the rearwardly facing ends 56 of the front support projections 48 define the front ends of the notches and the forwardly facing ends 58 of the rear support projections 5i define the rear ends of the notches.
The intermediate walls 6%) also carry front and rear support projections 62, or at the top thereof. These intermediate Walls so are spaced from the side walls by a front bridging member 8% and a rear bridging member 82. While the walls as, as are shown as being evenly spaced, they could obviously be spaced an unequal distance to support rolls of different widths. The intermediate support projections 62, 64 are wider than side support projections 48, 59; thus enabling them to act as common supports for two bearing spools 14. Each intermediate support projections 62, 64 is composed of longitudinal edges 66, 68, erminating in forwardly and rearwardly facing inner ends ill, '72 which cooperate with the longitudinal edges 74 of the spanning webs 76 to define notches 78. The spools are inserted in, locked between, and removed from the support projections 62, 64 in the same manner as shown in F188. 4-7.
Summary As is apparent from the drawings and the above specification, a tape dispensing device has been provided which is easily and economically manufactured, and which has bearing spools which may be niclily inserted and removed so as to facilitate quick interchange of rolls.
