COMPLETE SPECIFICATION STANDARD PATENT Name of Applicant: Actual Inventor Address for service is: Ching-Hsiang WANG Ching-Hsiang WANG WRAY ASSOCIATES Level 4, The Quadrant 1 William Street Perth, WA 6000 Attorney code: WR Invention Title: Band-Type Dispenser for Wrap Film The following statement is a full description of this invention, including the best method of performing it known to me:- -2- Band-Type Dispenser for Wrap Film Field of the Invention This invention relates to a band-type dispenser for wrap film, particularly to one provided with a base formed with a chamber, a positioning bracket respectively fixed at two sides of the chamber for supporting a roll of wrap film thereon, an endless band device installed in the base and having at least one endless band electrically moved to shift out wrap film, a cutter unit positioned in front of the endless band for cutting off the wrap film. It can automatically move and cut the wrap film, keeping a piece of cut wrap film flat and smooth, without entangling, enabling a user to use it conveniently and safely.
Description of the Prior Art Nowadays, wrap film is indispensable in general households, used for wrapping food or covering a container, such as bowls, saucers, cups, etc. preventing floating dirt in the air from smearing food or flies or insects from polluting food. Moreover, it can prevent food from dehydrating when food wrapped with wrap film is stored in a refrigerator, or it can seal food for cooking in a microwave cooker, and hold cooked food.
A conventional wrap film as shown in Fig. 1, a roll of conventional wrap film is placed in an elongate case, which has a swingable cover, with an elongate exit formed between the swingable cover and the case, and a saw-teeth blade fixed at a side edge of the exit.
In using, the wrap film is pulled out from its roll, then the swingable cover is pressed with one hand with an outer end of the wrap film O held with another hand. Then the wrap film is pulled in such a D direction that the wrap film may be cut off by the blade. In traditional handling of cutting the wrap film, a user often presses one end of the Iswingable cover, instead of pressing and moving it toward the body, so the wrap film is not easily cut off owing to uneven pressing, causing entangling of the wrap film. Then the conventional wrap film is sometimes troublesome to use.
SIn addition, the saw-teeth blade is fixed outside of the case, so a ci user's hand may be hurt in cutting operation by the blade. Therefore, the conventional wrap film is often not safe for using.
SUMMARY OF THE INVENTION Throughout the specification, unless the context requires otherwise, the word "comprise" or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated integer or group of integers but not the exclusion of any other integer or group of integers.

0 5 DETAILED DESCRIPTION OF THE PREFERRED
EMBODIMENT
t A preferred embodiment of a band-type dispenser for wrap film in Sthe present invention, as shown in Figs. 2-5, includes a base 2, an endless band device 3, and a cutter unit 4 as main components combined together.
The base 2 is provided with a chamber 20 in its interior, a positioning bracket 21 respectively fixed at two sides of the chamber 20 for supporting a roll of wrap film 10, an auxiliary rotary rod 22 set in the chamber 20 for moving supplementarily the wrap film 10, a swingable cover 23 swingably connected to the base 2 to close on or open an upper side of the base 2.
The endless band device 3 is arranged in the base 2, composed of at least one endless band 30 with plural long straight grooves 300 closely spaced apart, a pair of rotatable shafts 31 spaced apart with a proper distance for the at least one endless band 30 to rest on to be moved by the rotatable shafts 31, a driving unit 32 combined with one of the rotatable shafts 31 and consisting of a synchronous motor 320, a changeover switch 322 and a press button 323. The motor 320 has a shaft 321 to rotate the relative rotatable shaft 31 for moving the at least one endless band 30 to circulate around the two rotatable shafts 31. Further at least one film separating guider 33 is provided just beside the at least one endless band 30 and has a -7curvy bottom slightly protruding than the outer surface of the at least one endless band 30 so that the at least one film separating guider 33 can guide the wrap film 10 to separate from the outer surface of the endless band 30 for a user to grip easily the outer end of the wrap film The cutter unit 4 is deposited in front of the endless band device 3, composed of a drive motor 40 connected to the press button 323 of the driving unit 32 via a power line to be turned on and off, a drive gear 400 positioned at an outer side of the drive motor 40, an elongate threaded rod 41 having one end fixed with a pinion 410 engaging with the drive gear 400, a blade fixer 42 possible to reciprocate along the threads of the threaded rod 41, a blade 421 fixed on one side of the blade fixer 42 and having its edge facing closely to the outer surface of the endless band 30, as shown in Fig.
3.
Next, in using, referring to Figs. 2, 3, 5 and 6, firstly, put a roll of wrap film 10 in the chamber 20 of the base 2 and hang it on the two brackets 21. Secondly, pull the outer end of the wrap film 10 around the auxiliary rotary rod 22 to make it placed on the outer surface of the at least one endless band 3. Thirdly, press the changeover switch 322 of the driving unit 32 to turn on the power, and then press the press button 323 to start the synchronous motor 320 to rotate the shaft 321 to drive the rotatable shaft 31 to move the endless band to circulate around the two rotatable shafts 31 so as to carry the wrap film 10 stuck on the at least one endless band 30, by which the wrap film 10 may move gradually along on the at least one film separating guider 33 and separate from the surface of the at least one endless band 30. Finally, when the wrap film 10 is moved out to a needed length, release the press button 323 to pause the synchronous motor 320 and at the same time to start the drive motor of the cutter unit 4 to drive the drive gear 400 to rotate the pinion 410 of the threaded rod 41 to force the threaded rod 41 to shift the blade fixer 42 along the threads of the threaded rod 41 towards the wrap film 10 on the at least one endless band 30 so that the blade 421 may cut lengthwise the wrap film 10, moving in one of the straight grooves 300 without cutting the at least one endless band itself. The cut piece of wrap film 10 can be neat and smooth as shown in Fig. 6. In this way, the band-type dispenser for wrap film in the invention is safe and automatically used, possible to be placed on a table or hung on a wall for use.
If the roll of wrap film 10 is needed to be replaced with a new one, as shown in Figs, 2 and 5, swing up the swingable cover 23, and take off the old roll of wrap film 10 and put on a new one on the brackets 21, with the outer end of the new roll of wrap film 10 pulled to extend around the auxiliary rotary rod 22 and placed on the at least one endless band 30, thus finishing changing operation.
While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
The present invention is not to be limited in scope by the specific embodiment described herein. These embodiment is intended for the purpose of exemplification only. Functionally equivalent features, methods are clearly within the scope of the invention as described herein.
