[0026] As Fig. 2a, 2b and 3 show, the present invention of the tape cutting dispenser 100 includes a body 110, a pair of holders 170 and a cutting device 200. The body 110 has two opposite walls 120, and each of the walls 120 has a hole 130 and an accommodating space 150 is formed between the two walls 130. In the present embodiment, the accommodating space 150 preferably is formed between the two walls 120, such that each of the walls 120 of the body 110 is not connected to each other. In other different embodiments, however, the wall 120 of the body 110 may be connected to each other to enclose the accommodating apace 150 (not illustrated). Two holders 170 are disposed within each of the holes 130 and restrictably moveable in the hole 130. The holder 170 has a protruding portion 172 for engaging with the ring core 710 of the tape 700.

[0027] In the embodiment shown in Fig. 3, the protruding portion 172 of the holder 170 preferably includes a cone casing 176, a top surface 178 and a flange 184, wherein the top surface 178 is located on the top end of the cone casing 176, and the flange 184 is disposed on the bottom end of the cone casing 176. In other embodiments, however, the protruding portion 172 may also be constructed of an arc-curved surface or/and other proper shapes. In the embodiment shown in Fig. 2b and 3, the surface of the protruding portion 172 (i.e. the corn casing 176) preferably has a plurality of dents 177, at least one of the surfaces of the dents 177 is disposed parallel to the top surface 178 for fixing the ring core 710 of the tape 700 to prevent the tape 700 from moves along the cone surface of the corn casing 176 (as Fig. 2b shown). The diameter of the top surface 178 is smaller than the diameter of the ring core 710 such that the ring core 710 of the tape 700 can pass through and engage with the corn casing 176.

[0028] In addition, in the embodiment shown in Fig. 3, the present embodiment further includes two covers 230 to cover the outside surface of the hole 130 of the wall 120. In other embodiments, however, the cover 230 and the outside surface of the wall 120 may also be integrately formed. Thus, when the holder 170 assembles in the hole 130 of the wall 120, the holder 170 has to assemble from inside (i.e., from the space between the two walls 120). The cover 230 preferably has at least one female connecting portion 232 extending out of a rim of the holder 170 while the wall 120 around the hole 130 has a male connecting portion 122 for engaging with the female connecting portion 232. The above-mentioned of the female connecting portion 232 is preferably being a side border which has an opening, and the male connecting portion 122 is preferably being a protrusion, such that the protrusion is capable of engaging with the side border. In another embodiment, however, the arrangement of the female connecting portion 232 and the male connecting portion 122 may be reversed or use other proper elements, such as hook-loop, Velcro tape, fastening tape, etc.

[0029] The cutting device 200 is disposed on the body 110 opposite to the accommodating space 150. The cutting device 200 includes a cutting blade 210 and a bladed seat 220, wherein the cutting blade 220 is disposed on the bladed seat 220. A user may pull out the tape 700 and then take an appropriate length of the tape to cut it off on the cutting device 200. Moreover, the tape cutting dispenser 100 further has a base 190 for assembling beneath the body 110. A plurality of clips 192 are disposed on the top edge of the base 190 for engaging with the fasteners (not illustrated in the drawings) which are disposed corresponding to the clips 192. In another embodiment, however, the base 190 and the body 110 may also be integrately formed.

[0030] Please also refer to Fig. 4, each of the protruding portions 172 of the holders 170 protrudes toward the opposite wall 120 along an axial direction A. The holder 170 further has an elastic element 180. In the preferred embodiment, inner center of the holder 170 has a first positioning pillar 174 of the axial direction A for engaging with one end of the elastic element180; inner surface of the cover 230 has the second position pillar 234 corresponding to the first positioning pillar 174 so as to engage with the other end of the elastic element 180. In another embodiment, however, the inner surface of the cover 230 may also be disposed without the second positioning pillar 234, the end of the elastic element 180 may simply contact with the inner surface of the cover 230 without further engagement. The first positioning pillar 174 and the second positioning pillar 234 mentioned-above are preferably a cylinder, and their diameter are smaller than the diameter of the elastic element 180. In other embodiments, however, the first positioning pillar 174 and the second positioning pillar 234 may also be a trough (not illustrated) for receiving the two ends of the elastic element 180. In addition, the elastic element 180 is preferably a spiral compression spring. In other embodiments, however, the elastic element 180 may also be an extension spring, a torsion spring or other proper springs.

[0031] Moreover, one side of the wall 120 around the hole 130 is preferably having a limiting portion 126 corresponding to the flange 184 for restricting the movement of the holder 170 along the axial direction A. In other words, when no external force is exerted to the elastic element 180, the flange 184 of the holder 170 will contact and restrict by the limiting portion 126 of the wall 120 due to the extensibility of the elastic element 180. At the same time, the two top surfaces 178 of the holder 170 preferably do not contact with each other.

[0032] In order to further illustrate the present invention, relating steps and various embodiments thereof are described below. As Fig. 5a and 5b shows, when the tape 700 is inserted into the tape cutting disperser 100, the tape 700 contacts with the protruding portion 172 of the holder 170, such that the holder 170 is forced to bend downwardly and away from the axial direction A. In this stage, the elastic element 180 disposed inside the holder 170 will be axially compressed after receiving the external force and bend away from the axial direction A. The limiting portion 126 in association with the flange 184 of the holder 170 to confine the holder 170 within the hole 130 of the wall 120. Therefore, when the tape 700 pushes the holder 170 downwards, the elastic element 180 will be axial compressed and downwardly bend away from the axial direction A simultaneously until the ring core 710 of the tape 700 engages and positions on the protruding portion 710 of the holder 170. Afterwards, a rebound elastic force of the elastic element 180, recovers the holder 170 back to its original length and position.

[0033] Fig. 6a and 6b illustrate the disassembling of the tape and the tape cutting dispenser. When the tape 700 pulls the holder 170 upwards, the elastic element 180 disposed inside the holder 170 will be axially compressed and bent upwards away from the axial direction A. As shown in the present embodiment mentioned-above, the holder 170 is confined within the hole 130 by means of the limiting portion 126 of the hole 130. After the tape 700 entirely disengages from the holder 170, the elastic element 180 recovers the holder 170 back to its original length and position. Therefore, even though the size of the tape 700 changes, when replacing the tape 700, the holder 170 may move inside the hole 130 and then rebound quickly by means of the elasticity of the elastic element 180.

[0034] In order to increase the stability of bending motion away from the axial direction A of the holder 170, the holder 170 further has at least one guiding portion 182 disposed on the rim of the flange 184, as Fig. 7 shown. At least one guiding groove 124 corresponding to the guiding portion 182 is disposed on the wall 120 which enclosing the hole 130 for guiding the guiding portion 182. In the embodiment shown in Fig. 7, the width of the guiding groove 124 is greater than the width of the guiding portion 182, such that the holder 170 can be bent appropriate ranges/angles. When assembling or disassembling the tape with the tape cutting dispenser, the bending ranges/angles away the axial direction A of the holder 170 will be limited to the guiding groove 124, thus, unnecessary interference between the flange 184 and the side wall of the hole 130 can be avoided, and allow the holder 170 to return to its original position/status.

[0035] Fig. 8a, Fig. 8b and Fig. 9 show another preferable embodiment of the present invention. In the present embodiment, the holder 170 may also be replaced by a holder module 300. The holder module 300, which includes a holder 170 and the fastening sleeve 310, is disposed in the hole 130. The holder 170 is axially moveable along the fastening sleeve 310. In the embodiment shown in Fig. 8a and Fig. 8b, a pair of the guiding portions 182 are disposed on the rim of the flange 184 of the holder 170 while the inner wall of the fastening sleeve 310 has two second guiding groove 340, thereby the guiding portion 182 can be moved axially along the second guiding grooves 340. In particular, the dimension of the second guiding groove 340 is preferably greater than the width of the guiding portion 182, such that the guiding portion 182 can be bent away from the axial direction A with appropriate ranges/angles. The shape of the guiding portion 182 is preferably an arc shape so as to move smoothly at the second guiding portion 340.

[0036] Furthermore, in the present embodiment, the limiting portion 126 is preferably disposed on the fastening sleeve 310 which is corresponding to the rim of the cover 230 for engaging with the flange 184 of the holder 170. One side of the fastening sleeve 310 and the cover 230 are preferably integrately formed to cover the outside surface of the hole 130 of the wall 120. The side wall of the fastening sleeve 310 further forms at least one opening 320 while the wall 120 near the hole 130 has at least one hook 330 engaging with the opening 320. Therefore, the holder module 300 can be engaged with the opening 320 of the fastening sleeve 310 to position in the hole 130 by the hook 330.
