Abstract
A tape dispenser includes a handle, and a base plate which is disposed at an end of the handle, which has a tape mount pivoted at back side thereof and a seat member disposed at front side thereof. The seat member provides a cylinder at front side thereof for free rotating, a cutter at front end thereof above the cylinder and a plate at front end thereof between the cylinder and the cutter. An attracting piece is disposed on the plate of the seat member, which can produce static electricity on the surface thereof. The attracting piece has an adhesive layer at back side thereof, which can make the attracting piece secured at the plate and can prevent the static electricity on the attraction piece spreading to the seat member. Thus, the tail of the tape can be attracted by the attracting piece.
Description




FIELD OF THE INVENTION




The present invention relates to a packing tool, and more particularly to a tape dispenser, which can hold the tail of tape on the dispenser.




BACKGROUND OF THE INVENTION





FIG. 1

shows a conventional tape dispenser


90


, which is applied to the workplace, such as the warehouse department of a factory, the post office or delivery company where need to pack boxes and the like a great quantity and frequently. Please refer to

FIG. 1

, the tape dispenser


90


disposes a tape roll thereon. The tape


91


is drawn out and runs along a cylinder


92


with a pressing piece


93


pressing the tape


91


. Then the tape


91


is drawn to the cutter


94


.




In operating, please refer to

FIG. 2

, operator holds the handle of the tape dispenser


90


and attaches the tail of the tape


91


on the box


95


first. Thus, operator can move the dispenser


90


to draw the tape


91


out to make it attached on the box


95


. After packed the box


95


, the operator can turn the dispenser


90


an angle to make the cutter


94


cutting the tape


91


off. However, when the cutter


94


cuts the tape


91


off, there is nothing to hold the tail of the tape


91


that will make the tape tail waving freely. Operator needs to holds the tail of the tape


91


to make it attached on another box


95


first, and then he/she can draw the dispenser


90


to make the tape


91


attached on the box.




An earlier invention to fix the problem is to provide a metal seat member, which is the element labeled


96


in FIG.


1


and FIG.


2


. The metal seat member


96


can produce static electricity on the surface to make the plate, which is the element labeled


97


in FIG.


1


and

FIG. 2

, between the cylinder


92


and the cutter


94


attracting the tail of the tape


91


. Thus, the plate


97


will attract the tail of the tape


91


the after the tape


91


being cut. But I found the seat member


96


can not concentrate the static electricity on the plate


97


only, the static electricity will spread to the entire seat member


96


. So sometime the plate


96


is fail to attract the tape.




SUMMARY OF THE INVENTION




The primary object of the present invention is to provide a tape dispenser, which can hold the tail of tape fixedly after the tape being cut off.




According to the objective of the present invention, a tape dispenser comprises a handle. A base plate is disposed at an end of the handle, which has a tape mount pivoted at back side thereof and a seat member disposed at front side thereof. The seat member provides a cylinder for free rotating and a cutter. An attracting piece is disposed on the seat member between the cylinder and the cutter, which can produce static electricity on the surface thereof. Thus, the tail of the tape can be attracted by the attracting piece.

DETAIL DESCRIPTION OF THE INVENTION




Please refer to FIGS. from

FIG. 3

to

FIG. 5

, the prefer embodiment of the present invention provides a tape dispenser


10


, which comprises a handle


12


, a base plate


14


secured at the topside of the handle


12


, a tape mount


16


pivoted at the back side of the base plate


14


and a seat member


18


secured at front side of the base plate


14


. The seat member


18


pivots a cylinder


22


at front side thereof and secures a cutter


24


above the cylinder


22


. The elements of the tape dispenser


10


are the same as the prior art, so I will not describe the detail.




Please refer to FIG.


4


and

FIG. 5

, the seat member


18


of the tape dispenser


10


has a rectangular plate


19


at front end thereof between the cylinder


22


and the cutter


24


, which attaches an attracting piece


32


thereon. The attracting piece


32


is made of polyvinyl chloride (PVC), which has apertures


33


thereon. The area of the attracting piece


32


is substantial equal to the plate


19


. The attracting piece


32


has an adhesive layer


34


at back side thereof for attaching the attracting piece


32


on the plate


19


securedly. In this prefer embodiment, the adhesive layer


34


of the attracting piece


32


is a twin adhesive piece, which is made of foam and has thickness of substantial 0.2 mm. There are other ways to attach the attracting piece


32


on the plate


19


of the seat member


18


, such as providing a liquid adhesive on the back side of the attracting piece


19


to make the attracting piece


32


attached on the plate


19


directly. After the adhesive is solidified, it will form the adhesive layer. The attracting piece


32


on the plate


19


by hot pressing.




The attracting piece


32


is to provide the capacity of static electricity attraction, so the attracting piece


32


also can be chosen from another macromolecular material or metal piece, such as aluminum piece, which can produce static electricity easier and can hold the electric charges on the surface. In operating, the tape will rub against the attracting piece


32


rapidly to make the attracting piece


32


producing static electricity on the surface. This is we call it as “frictional electricity” in physics.




As we know, the foam and the adhesive are insulations, so the adhesive layer


34


of the attracting piece


32


has another function of isolating the attracting piece


32


from the plate


19


so that the static electricity cannot spread to the seat member


18


. Thus, the static electricity is concentrated at the attracting piece


32


only to provide a larger static electricity attraction.




In operating, please refer to

FIG. 6

, when the user operates the tape dispenser


10


of the present invention make the tape


40


seal a box


50


and drives the cutter


24


to cut the tape


40


, the tail of the tape


40


attracted by the attracting piece


32


by means of the static electricity produced on the attracting piece


32


. Thus, the user can continue the next packing work without having to hold the tail of the tape


40


. The efficiency of the packing work is greatly increased.




In the prefer embodiment as described above, I provide apertures


33


on the attracting piece


32


are to facilitate the attracting piece


32


attached on the plate


19


of the seat member


18


fixedly.




The advantages of the present invention are:




1. It only needs to attach the attracting piece on the seat member, there is no further element is added in the tape dispenser


10


of the present invention. It has lower cost than the prior art.




2. The adhesive layer further has a function of isolating the attracting piece from the seat member to prevent the static electricity spreading to the seat member. Thus, the attracting piece can securely hold the tail of the tape for a longer time, because of the static electricity is concentrated at the surface of the attracting piece.
