The dispenser of this invention includes a spindle for supporting the roll of tape. The spindle is carried by a backing plate having suction means applied thereto for the purpose of removably securing the dispenser to a door or window glass or similar supporting structure. A cover is applied over the roll of tape and is journaled for rotation about the axis of the spindle. A knob forms a part of the dispenser and is utilized to move the dispenser from one location to another upon the glass supporting structure. The loosened end of the tape extends through the cover with the tape roll and cover being rotatable about the axis of the spindle to permit the tape to be pulled from the dispenser at various angular positions without releasing and repositioning the dispenser upon the supporting structure.
Accordingly, it is an object of this invention to provide a tape dispenser which can be removably secured to a glass or similar smooth surface supporting structure to accommodate the removal of the tape from the dispenser.
Another object of this invention is to provide a dispenser which is for glass security foil and which can be applied to a window or similar glass closure for the purpose of assisting in applying the foil to the closure.
Another object of this invention is to provide a tape dispenser which is for glass security foil and which simplifies the operation of applying the foil to a glass closure.
Still another object of this invention is to provide a tape dispenser which is of economical construction.
Other objects of this invention will become apparent upon a reading of the inventions description.
BRIEF DESCRIPTION OF THE DRAWINGS A preferred embodiment of this invention has been chosen for purposes of illustration and description wherein:
FIG. I is a perspective view showing the dispenser secured to a glass door.
FIG. 2 is an enlarged perspective view of the dispenser in FIG. I.
FIG. 3 is a front view of the dispenser of FIG. 1.
FIG. 4 is a sectional view taken along line 4-4 of FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT The preferred embodiment illustrated is not intended to be exhaustive or to limit the invention to the precise form disclosed. It is chosen and described in order to best explain the principles of the invention and its application and practical use to thereby enable others skilled in the art to best utilize the invention.
The embodiment of the dispenser of this invention shown in the drawings is designated by the reference numeral I and is depicted in FIG. I as being applied to the glass 12 of a door 14. Dispenser 10, as seen in greater detail in FIGS. 2-4, icludes a back plate I6 having a front face 18 and a rear face 20. A fixed spindle 22 protrudes perpendicuarly from front face I8 of the back plate. Spindle 22 includes a generally cylindrical body part 24 and a reduced neck part 26 which is separated from the body part by a shoulder 28.
A pair of suction cups 30 are connected to the rear face 20 of back plate 16. Cups 30 provide the means by which dispenser I0 can be attached to glass I2 of door 14 during use of the dispenser. A boss 32 is formed upon rear face 20 of back plate 16, preferably oppositely located from spindle 22. Suction cups 30 and boss 32 are spaced so as to form a triangular three point contact with glass 12.
A cover 34 is mounted over spindle 22. Cover 34 includes a circular disk-shaped front 36 having an annular rearwardly projecting flange 38 formed about its peripheral edge. Cover 34 has a center opening 40 formed in its front 36. Neck part 26 of spindle 22 extends through opening 40 of the cover. Flange 38 of cover 34 has a slot 42 formed therein. Slot 42 is utilized to accommodate the loosened end 44 of a roll 46 of tape which is journaled upon spindle 22. Additionally, an opening 48 may be formed in front 36 of the cover so as to expose a portion of tape roll 46, thus enabling the user of the dispenser to have a visual indication of the amount of tape remaining upon the roll.
A knob 50 is secured to spindle 22 and serves as a grip means to enable the dispenser to be removed from one location and repositioned at another location upon glass 12 of door 14. A threaded stud 52 is carried by spindle 22 and includes an end portion which protrudes forwardly from end face 54 of the neck part 26 of the spindle. Knob 50 is threaded upon the protruding end portion of stud 52 and is brought to bear against spindle end face 54 with the angular margin 35 of cover 34 at opening 40 therein being located between the knob and shoulder 28 of the spindle. The spacing between knob 50 and spindle shoulder 28 slightly exceeds the thickness of cover 34 at the margin 35 of opening 40 with the cover being free to rotate about spindle neck part 26.
To load dispenser 10 with a roll 46 of glass security foil or tape, knob 50 is unscrewed from stud 52. Cover 34 is then removed from spindle 22 and the roll of tape positioned against back plate I6 with spindle 22 extending through the center opening in the roll. The center opening of each roll of security tape is generally formed by a paper core 56. Core 56 fits upon body part 24 of the spindle with a slight frictional fit which while permitting the roll 46 of tape to rotate about the spindle will prevent an overrun of the roll within the dispenser after a selected length of tape has been pulled from the dispenser. After the roll of tape is placed upon the exposed spindle 22, the exterior end 44 of the tape is inserted through slot 42 in cover 34 as the cover is placed over the roll with neck part 26 of the spindle protruding into opening 40 in the cover. After cover 34 is so placed over the roll 46 of the tape, knob 60 is threaded onto stud 52 and brought to bear against end face 54 of the spindle to secure the cover upon the spindle. The dispenser is then positioned against glass 12 of door 14 and the loosened end 44 of the tape pulled from the dispenser and applied by an adhesive about the perimeter of the door. As the tape is pulled from the dispenser and applied to glass 12, the angular relationship of the loose end 44 of the tape relative to dispenser will vary causing rotation of cover 34 relative to back plate l6. After one section of the tape has been applied to the glass 12, the dispenser can be loosened from the glass by a pull upon knob 50 and repositioned at another selected location on the glass without cutting the tape.
It is to be understood that the invention is not to be limited to the details above given but may be modified within the scope of the appended claims.
What I claim is:
l. A dispenser in combination with a roll of tape, comprising a back plate having front and rear faces, cover means positioned over said back plate front face, spindle means positioned between said back plate and cover means, said roll of tape being coiled upon itself about an open center and being rotatatively supported upon said spindle means at its said open center for rotation relative to said cover means and back plate, suction means carried at the rear face of said back plate for releasably securing said dispsenser to a supporting surface as said tape is pulled from said dispenser, means for securing said cover plate over said back plate front face and means journaling said cover means for rotation relative to said back plate and tape, said cover means having an opening therein to accommodate the loosened end of said tape as said tape is pulled from the dispenser with said dispenser secured to said supporting surface by said suction means whereby said tape may rotate separately from or as a unit with said cover means.
2. The dispenser of claim 1 wherein said means for securing said cover means over said back plate front face constitutes grip means for causing said dispenser to be removed from one location and to be repositioned in another location on said supporting surface.
3. The dispenser of claim I wherein said spindle means includes a body portion for supporting said tape roll and a reduced neck portion separated from said body portion by an annular shoulder, said neck portion terminating in said end face, said cover means having an annular marginal part defining a center opening therein, said spindle means neck portion protruding into said center opening with said center opening defining marginal part being located with rotatable clearance between said grip means and spindle means annular shoulder.
4. The dispenser of claim 1 wherein said suction means constitutes two suction cups, a boss means projecting from the rear face of said back plate, said cups and boss means constituting three points of contact with said supporting surface.
