Definitions

  • This invention relates to tape dispensers having a cutting edge on a moving door.
  • Conventional tape dispensers often have a tape roll support for holding the core of a tape roll and a side wall extending from the tape roll support to a cutting blade. These types of dispensers leave one side of the roll of tape uncovered. The uncovered side can become contaminated with dirt, dust, or other debris.
  • Two-sided tape dispensers can be used to further contain the roll of tape.
  • Conventional two-sided tape dispensers such as the dispenser shown in U.S. Design Patent No. D510,951 (Carlson et al), include a second side wall to cover the roll of tape. To open and gain access to the tape roll support, the side walls are typically twisted relative to one another.
  • Tape dispensers that are capable of entirely concealing the tape within the dispenser are disclosed in U.S. Patent No. 7,641,087 (Chang) and U.S. Patent Application Pub. No. 2010/0200633 (Hsu et al). These dispensers typically include a housing with a circular perimeter and a tape dispensing mechanism.
  • the tape dispensing mechanism comprises an opening in the housing wall and a cutting edge.
  • the cutting edge can be located on a moving door that is connected to the housing wall by a hinge. When the dispenser is not in use and the door is closed, the door covers the opening in the housing wall. When the door is open, tape can be pulled through the opening in the housing wall and then cut with the exposed cutting edge.
  • tape dispensers that have a cutting edge disposed on a moving door such as the tape dispensers disclosed in Chang and Hsu et al. suffer from a drawback in that when a user is finished using the dispenser and closes the door cover, the tape often folds on itself adhesive -to-adhesive. This is not typically desirable because it creates an unusable section of tape.
  • the user In order to avoid this folding problem, the user must press down on the non-adhesive side (i.e., the low adhesion backsize (LAB) side) of the tape to ensure that the tape folds on itself LAB-to-LAB instead of adhesive-to-adhesive. It would be desirable to have the tape automatically fold on itself LAB-to-LAB when the user closes the door so that the user does not have to take these additional steps.
  • LAB low adhesion backsize
  • the present invention provides a tape dispenser comprising a tape roll housing comprising a tape dispensing mechanism comprising
  • a moving cover connected to the housing by a hinge
  • the first landing surface and the second landing surface are configured such that when at least a portion of the tape is adhered to the first landing surface and at least a portion of the tape is adhered to the second landing surface, the tape is formed into a cross-web concave shape between the first landing surface and the second landing surface.
  • Fig. 1 is an exploded perspective view of an embodiment of a tape dispenser of the invention.
  • Fig. 2 is a sectional view of the tape dispenser of Fig. 1 with the moving cover open.
  • Fig. 3 is a sectional view of the tape dispenser of Fig. 1 with the moving cover closed.
  • Fig. 4 is a perspective view of an embodiment of a tape dispenser of the invention.
  • Fig. 5 is another perspective view of the tape dispenser of Fig. 4.
  • Fig. 6 is a perspective view of another embodiment of a tape dispenser of the invention.
  • Fig. 7 is a perspective view of an embodiment of a tape dispenser of the invention.
  • Fig. 8 is a perspective view of an embodiment of a tape dispenser of the invention.
  • Fig. 1 is an exploded perspective view of exemplary tape dispenser 100 for dispensing a roll of tape 500.
  • Tape dispenser 100 comprises tape roll housing 200, which includes base 202 and cover plate 204, and tape dispensing mechanism 300.
  • tape roll housing 200 is circular to follow the contour of circular roll of tape 500 contained within.
  • the shape of tape roll housing 200 can be other shapes, sizes or configurations.
  • base 202 has a plurality of connection openings or holes 206 on its edge that engage with connecting pegs 208 on cover plate 204 to connect cover plate 204 to tape roll housing 200.
  • Base 202 may optionally include a tape core support.
  • Tape core support 210 engages and supports the core of tape roll 500. As shown in Fig.
  • tape core support 210 includes first interlock 212 and second interlock 214 that extend from base 202 into tape roll housing 200.
  • First interlock 212 and second interlock 214 can slightly flex to allow tape roll 500 to pass over them, but the ends of the interlocks stop tape roll 500 from being released from them.
  • the tape support could be a circular projection extending from base 202 into tape roll housing 200. Regardless of its exact configuration, the tape core support aids in restraining tape roll 500 while in tape roll housing 200.
  • Tape dispenser 100 includes tape dispensing mechanism 300.
  • Tape dispensing mechanism 300 comprises a dispenser opening 310 in base 202 of tape roll housing 200, moving cover 312 connected to base 202 by hinge 314, and cutting edge 316 located at the outermost edge of moving cover 312.
  • section 322 of the circular wall of base 220 which has a patterned outer surface. Adjacent to an end of section 322, dispenser opening 310 (shown as a slit in this embodiment) is provided, through which tape 500 can be pulled out of base 202.
  • Moving cover 312 can be shaped correspondingly to section 322 so that moving cover 312 can be fitted over the patterned surface of section 322.
  • Moving cover 312 has locking protrusions 318 that engage with notch 320 to keep moving cover 312 in a locked, closed position.
  • Moving cover 312 is connected to base 202 by hinge 314, which allows for pivoting movement of moving cover 312 from an open position as shown in Fig. 2 to a closed position as shown in Fig. 3.
  • moving cover 312 can be flipped up to reveal or closed to cover the patterned surface of section 322.
  • moving cover 312 On its inner surface, moving cover 312 may have a similar or the same patterned surface as the patterned surface of section 322 in order to interface with the patterned surface of section 322 when moving cover 312 is closed.
  • Cutting edge 316 is located at the outermost edge (opposite of the hinge) of moving cover 312. Cutting edge 316 may be integrally formed with moving cover 312 or it may be a separate blade that is installed in moving cover 312.
  • the tape dispensing mechanism also includes two landing surfaces.
  • a landing surface is a surface that the tape will stick to prior to cutting the tape with the cutting edge.
  • exemplary tape dispenser 1000 comprises first landing surface 1324 located at the edge of dispenser opening 1310 closest to hinge 1314 (i.e., first landing surface 1324 defines the "bottom" edge of dispenser opening 1310).
  • Second landing surface 1326 is located on moving cover 1312 adjacent to cutting edge 1316.
  • First landing surface 1324 and second landing surface 1326 are configured such that when at least a portion of the tape is adhered to first landing surface 1324 and at least a portion of the tape is adhered to second landing surface 1326, the tape is formed into a cross-web concave shape between the first landing surface and the second landing surface. It has been found that when the tape is formed into a cross-web concave shape (i.e., when it is cupped from side to side along the length of tape to be folded when the moving cover is closed), it will resist down-web folding in the concave direction. The landing surfaces do not have to make continuous contact with the tape. However, if the tape is allowed to dispense in a planar arrangement (for example, when the first landing surface and the second landing surface are planar), it will frequently fold on itself adhesive-to-adhesive.
  • first landing surface 1324 can be concavely curved in the cross-web direction while second landing surface 1326 is planar.
  • first landing surface 1324 can have more of a "V" shaped notch than a curve.
  • second landing surface 1326 is also concavely curved in the cross-web direction.
  • second landing surface 1326 can have more of a "V" shaped notch than a curve.
  • first landing surface 1324 can be curved (while the other half of the first landing surface is planar) and the opposite half of second landing surface 1326 can be curved (while the other half of the second landing surface is planar).
  • the curvature of the landing surfaces can vary. For example, it may be circular or elliptical.
  • One way of describing the curvature is with a "rho" value.
  • Computer aided design (CAD) systems typically have a conic curve function.
  • the shape of a conic curve can be defined by its rho value. For example, rho of 0.5 gives a parabola, and greater or lesser than 0.5 gives hyperbolas or ellipses respectively.
  • the first landing surface has an elliptical shape with a rho value of about 0.42.
  • the second landing surface has a circular shape with a 7 inch radius.
  • the curvature of the second landing surface can be very slight. In some embodiments, the curvature of the second landing may not be readily noticeable to the naked eye.
  • first landing surface and the second landing surface are configured such that when at least a portion of the tape is adhered to first landing surface and at least a portion of the tape is adhered to second landing surface, the tape is formed into a cross-web concave shape between the first landing surface and the second landing surface.
  • the improved tape dispensing mechanism described above can be used in various tape dispensers including, but not limited to, tape dispensers such as those described in U.S. Patent No. 7,641,087 (Chang) and U.S. Patent Application Pub. No. 2010/0200633 (Hsu et al.), which are incorporated herein by reference in their entirety.
