Abstract
There is provided a dispenser for rolled material having a pair of side walls and a top panel with cutting means that can be engaged over the material with a supporting back edge being connected through the circular formed male-female connection. The semi-circular side walls are designed in a way that allows the outermost free end of the material to be extended over the cutting edge so as to be easily engaged or grasped to urge the material from the dispenser for cutting a desired length by moving the material downward against the teeth of the cutting edge. The spacing between the inner side of the semi-circular side walls and the free portion of the material provides enough space for an individual's index finger, and therefore the ability to easily grasp a length of material for dispensing.

21 ~0939 ~i~l~; DISPENSER FOR ROLLED NATERIAL
Inventor: NARK NCLEAN
P~ OF TI~E lr. v Ll. L _ Field of th~ Tnvention This invention is generally directed to dispensers for rolled material, such as a tape ~ p-~n~ r. More specifically, the present invention is directed to a portable type of dispenser supporting a spool of adhesive or non-adhesive rolled material relative to a cutter so that a desired length of the material may be extended from the spool and thereafter severed by engaging the material with the cutter. The ~l; qp~nC~r is designed to be supported by a user's thumb and index fingers of the left or right hand, depending upon the dexterity of the individual utilizing the lsiPp~nq~r. By holding the dispenser, the user's hand supports the rolled material.
De~cription of Prior Art There are currently many types of dispensers for rolled material, many of which have been designed for a specific purpose or to provide special dispensing characteristics. Dispensers vary in design or conf iguration ~.or~n-l i n~ upon the type of material, ie .
tape, ribbon, thread, string etc., to be dispensed and also whether the material is adhesive or non-adhesive.
21~939 The most common types of dispensers are adhesive tape dispensers that normally include a housing for supporting a spool or roll of adhesive tape in spaced relationship with a cutter.
Conventional adhesive tape spools or rolls are manufactured in standard sizes to fit standard home or office replacement-type dispensers. When a roll of adhesive tape is exhausted, a replacement roll may be easily mounted in the dispenser.
As opposed to replacement-type dispensers, there are other types of dispensers which are specif ically manufactured to be disposed of once the included roll of material has been fully dispensed. Such dispensers are normally constructed of a plastic material or a combination of plastic and paperboard or cardboard.
Some types of tl;F:p~n~:F.rs for rolled materials have proven awkward to utilize. For example, many people have experienced the frustration in attempting to f ind the free edge of an adhesive tape roll and then hold the r~;~r~n~r housing with one hand while cutting the tape with the other. Unfortunately, most conventional adhesive tape tl;~:p-~n~/~rs, which are of low cost and available to the average C~ r for personal use, require that the dispensing apparatus be held with one hand while the material is drawn out and cut off using the other hand.

length of the tape folds onto itself and adheres to itself thereby necessitating the tape be pulled apart before it can be utilized.
A further problem with the conventional low cost tape dispensers, especially those for adhesive and another type of sealing tape, is that the dispenser is not designed to be self-supporting.
Therefore, each time a length of tape is cut, the dispenser must be placed on a surface, and is often misplaced beneath packages and articles which are being wrapped or sealed.
Still another problem is that many dispensers are constructed for a specific size of rolled material, ie., having a predefined width and diameter. This approach for designing dispensers has resulted in many different sizes of dispensers for different sizes of materials.

Fig. 2 shows a second prior art device being a replacement type dispenser which can be used for dispensing tape with either the adhesive or the non-adhesive side being held outwardly.
Referring to the Figs. 3 and 4 of the drawings of the first ~mho~lir 1~ of the present invention, there is shown generally a combination of two parts being an elastic semi-circle shaped part 1 (sometimes referred to as the body of the dispenser) for the purpose of cutting the tape and at the same time supporting the apparatus to the tape spool, and a part 2 for the purpose of supporting the 21~939 .
di6penser and rolling the dispenser back.
With continued reference to Fig. 4, the body of the ~liPp~n~Pr 1 is formed by a pair of aligned parallel left and right side walls 11, 11', and a top panel 15 for the purpose of connPct;n~
the lef~ and right semi-circle shaped 6ide walls which starts from the edge of the inner side of semi-circle shaped and ends at the outer side of the semi-circle shaped element.
On the upper edge of the top panel 15, there are upward vertically sharp teeth 16 for the purpose of cutting the material.
At both ends of the row of cutting teeth 16, a protrusion 17 extends upwardly from the front upper edge of each side wall. This protrusion extends upwardly from each front upper edge of the side walls higher than the upper surface of the cutting means for preventing the cutting means from being damaged and user's hands from being hurt.
Referring still to Fig. 3 and Fig. 4, because of the elasticity of the side walls 11,11' of the dispenser, the tape roll can be easily put into the dispenser with the supporting bosses 13,13' into the inner side of the tape spool 30. Fig. 8 shows the spool 30 inserted in the dispenser.

circle shaped part 2, 2 ' around the centre point 12 ,12 ' . This is a useful function of the present invention for a variety of used and unused tapes in which the outermost diameter of the roll will vary.
Referring to Figure 5, the dispenser ;ncl~ a pair of generally aligned parallel left and right side walls 11,11', sometimes being semi-circular in shape, for holding and dispensing adhesive and non-adhesive material from a roll. A top panel 15 sonn~ct~: the corresponding the upper segments of the left and right side walls and includes cutting teeth 16 on its top portion for the purpose of cutting the material. There is also provided behind the top panel and extending between the side walls a front wall 118 for supporting and pushing the tape down on the surface.
On the inner side of each side wall there is provided a cylindrical boss 120,120' of appropriate dimensions for supporting a spool of rolled material. A tape roll can be easily put into the supporting edge due to the elasticity or resiliency of the material from which the dispenser is fabricated.
The front portion of the top panel 15 forms a protruding rim of a small height extending upwardly at its rear edge which serves as an easy-release planar r~tA;nin~ surface for releasably securing the material so as not to fall back against the roll when the zs d~Fpon~ r 1~ not in uso and ~ po~itionlng ~ember rOr ~aint:ining t e 21~0g3g .
end portion of the material at a certain high position relative to the surface of the top panel.
The design of the side walls 11,11' of the dispenser provides enough free space for the user's index finger to reach the free length of the material and grab the n^--;ning material between the supporting edge and the cutting element.
This invention consists also of a 6upporting edge that holds the dispenser apparatus to the roller and is placed on the outermost side of adhesive or non-adhesive material. Considering the free end of the tape, the semi-circle shaped element positioned on one side and the supporting edge positioned on the other side.
The supporting edge in the general form comprises a pair of parallel left and right side walls made of a resilient material such as plastic having aligned parallel side walls and a top tube-shaped edge connecting the upper segments of the left and right side walls for holding and ~ p~n~in~ adhesive and non adhesive tapes from a tubular roll. The tube form of the supporting edge serve as an easy moving element retaining surface for releasably securing the tape to prevent backward rotation of the tape. On each of the inner side of the left and right side walls of the supporting edge, there is provided a circular boss of about 8mm for supporting the roll. A roll can be easily put into the supporting edge due to its elasticity.
214~939 .
8~cond Em~r~A; r For the purpose of utilizing the present invention for packaging or sticking the material directly to a sheet of paper or other surfaces, some additional features are provided in a second Referring to the Fig. 5, the user must assemble the dispenser in a way that additional bosses 120,120' hold a portion of free material from the sticky side of it as shown in the Figs. 6a and 6b .
The user must hold the free end of the material with their fingers and roll a length of the tape through the provided space 122,122' with the sticky side of the material upward and the free end placed on the cutting teeth 16. The supporting bosses 120,120' are placed at the middle point of the inner side of the semi-circle shaped side wall6 11,11' to hold tape during use. The length of each supporting parts 121,121' is about 8mm to provide enough support for the roll .
Referring to Fig. 5 the supporting part 118 is provided for the purpose of packaging and the like. The middle edge of this part is shorter than the end edge, because a free space is needed to be created to grab the free portion of the material for subsequent usage. The user must hold this part 118 with their thumb and roll the , ~
spool and the dispenser backward. When the desired length of the material is reached and the material i5 placed to the surface properly, a cutting action is employed by bringing the cutting teeth against the material.
Referring to Fig. 5 there i5 shown a generally a tape dispenser of a single plastic part which is namely of an elastic semi-circle shaped part 1 for the purpose of cutting the tape and at the same time supporting the apparatus to the tape spool joined to a supporting part 2 for the purpose of supporting the dispenser when the user rolls the tape back. The semi-circle part 1 includes the side walls 11,11' and the top panel 15.
With continued reference to Figs. 5, 6a and 6b of the drawings, the semi-circle shaped part 1 is formed by a pair of aligned parallel left and right semi-circle shaped side walls 11,11 and a top panel 15 for the purpose of connecting the left and right semi-circle shaped side walls 11,11' which starts from the edge of the inner side of semi-circle shaped and ends at the outer side of the semi-circle shaped part. At the very end of the top panel 15 an upward vertically located sharp teeth 16 for the purpose of cutting the tape is placed. Beside the l~oth ends of the cutting teeth 16 protrusion 17 extends upwardly from the front upper edge of each side walls.
Because of the elasticity of the semi-circle shaped part 214~939 .
1 the tape roll 30 can be easily put into the semi-circle shaped part with the supported bosses 13,13' into the inner side of the tape spool 30. The semi-circular shape of the part 11,11' makes it possible that the user can adjust the position by rotating the supporting part 2,21' around the centre point 12 ,12 ' . This is a useful function of the present invention for a variety of used and unused tapes which will cause the outermost diameter of the tape varies.
The unique characteristics of the present invention permit it to perform consistently, also because the dispenser is made of plastic, its lifetime greatly exceeds the ordinary life of a roll of tape. Thus, if desired, the ~; ~pPn~r can be used over and over by removing the used spool 30 from the dispenser and replacing it with a new roll.
ThirO
Referring to Figs. 7a and 7b, showing the third embodiment of the invention, downward cutting teeth are provided to make it easy for non-adhesive materials to be extended backward so the desired point of the material is brought under the cutting teeth and then pulled upward against the teeth.
The semi-circular side walls, the front wall 118 and the top panel 15 define an opening 122 for dispensing of non-adhesive type of materials. At the lower part of the semi-circle shaped side walls 21~939 a pair of bosses are provided to support the cutting part of the apparatus to the tape's spool. Both left and right bosses extend about 8mm toward the inner side of the materials spool. They connect the dispenser's two parts and at the same time hold the apparatus to the spool. The male-female connection is designed in semi-circle shape, with the outermost side touching the inner side of the spool. When the material is rolled back by the user, the extended portion of the material pulls the supporting edge backward and the male-female connection moves freely backward in the spool.
Many other uses and variations of the present invention will be apparent to those skilled in the art, and while specific ho~l;r~ ts of this invention have been described, these are intended for regular purposes only. It is intended that the scope of the invention be limited only by the attached claims.

8~cond Em~r~A; r For the purpose of utilizing the present invention for packaging or sticking the material directly to a sheet of paper or other surfaces, some additional features are provided in a second Referring to the Fig. 5, the user must assemble the dispenser in a way that additional bosses 120,120' hold a portion of free material from the sticky side of it as shown in the Figs. 6a and 6b .
The user must hold the free end of the material with their fingers and roll a length of the tape through the provided space 122,122' with the sticky side of the material upward and the free end placed on the cutting teeth 16. The supporting bosses 120,120' are placed at the middle point of the inner side of the semi-circle shaped side wall6 11,11' to hold tape during use. The length of each supporting parts 121,121' is about 8mm to provide enough support for the roll .
Referring to Fig. 5 the supporting part 118 is provided for the purpose of packaging and the like. The middle edge of this part is shorter than the end edge, because a free space is needed to be created to grab the free portion of the material for subsequent usage. The user must hold this part 118 with their thumb and roll the , ~
spool and the dispenser backward. When the desired length of the material is reached and the material i5 placed to the surface properly, a cutting action is employed by bringing the cutting teeth against the material.
Referring to Fig. 5 there i5 shown a generally a tape dispenser of a single plastic part which is namely of an elastic semi-circle shaped part 1 for the purpose of cutting the tape and at the same time supporting the apparatus to the tape spool joined to a supporting part 2 for the purpose of supporting the dispenser when the user rolls the tape back. The semi-circle part 1 includes the side walls 11,11' and the top panel 15.
With continued reference to Figs. 5, 6a and 6b of the drawings, the semi-circle shaped part 1 is formed by a pair of aligned parallel left and right semi-circle shaped side walls 11,11 and a top panel 15 for the purpose of connecting the left and right semi-circle shaped side walls 11,11' which starts from the edge of the inner side of semi-circle shaped and ends at the outer side of the semi-circle shaped part. At the very end of the top panel 15 an upward vertically located sharp teeth 16 for the purpose of cutting the tape is placed. Beside the l~oth ends of the cutting teeth 16 protrusion 17 extends upwardly from the front upper edge of each side walls.
Because of the elasticity of the semi-circle shaped part 214~939 .
1 the tape roll 30 can be easily put into the semi-circle shaped part with the supported bosses 13,13' into the inner side of the tape spool 30. The semi-circular shape of the part 11,11' makes it possible that the user can adjust the position by rotating the supporting part 2,21' around the centre point 12 ,12 ' . This is a useful function of the present invention for a variety of used and unused tapes which will cause the outermost diameter of the tape varies.
The unique characteristics of the present invention permit it to perform consistently, also because the dispenser is made of plastic, its lifetime greatly exceeds the ordinary life of a roll of tape. Thus, if desired, the ~; ~pPn~r can be used over and over by removing the used spool 30 from the dispenser and replacing it with a new roll.
ThirO
Referring to Figs. 7a and 7b, showing the third embodiment of the invention, downward cutting teeth are provided to make it easy for non-adhesive materials to be extended backward so the desired point of the material is brought under the cutting teeth and then pulled upward against the teeth.
The semi-circular side walls, the front wall 118 and the top panel 15 define an opening 122 for dispensing of non-adhesive type of materials. At the lower part of the semi-circle shaped side walls 21~939 a pair of bosses are provided to support the cutting part of the apparatus to the tape's spool. Both left and right bosses extend about 8mm toward the inner side of the materials spool. They connect the dispenser's two parts and at the same time hold the apparatus to the spool. The male-female connection is designed in semi-circle shape, with the outermost side touching the inner side of the spool. When the material is rolled back by the user, the extended portion of the material pulls the supporting edge backward and the male-female connection moves freely backward in the spool.
Many other uses and variations of the present invention will be apparent to those skilled in the art, and while specific ho~l;r~ ts of this invention have been described, these are intended for regular purposes only. It is intended that the scope of the invention be limited only by the attached claims.
