Description
- The present invention relates to a tape dispenser, and more particularly to a protective tape dispenser.
- A conventional tape applicator includes a handle, a blade holder and a tape roll seat above the handle. The blade holder is disposed in front of the tape roll seat. A roller is provided below the blade holder. A blade is insertedly connected to the blade holder. A protective tape roll is sleeved onto the tape roll seat. In use, one end of the protective tape of the protective tape roll is attached to a product to be sealed. Then, with the rotation of the protective tape roll, the protective tape is pulled to stretch an appropriate length. During the stretching process, the protective tape of the protective tape roll is attached to the surface of the product. Finally, the protective tape is cut by the blade, so that the packing process can be effectively simplified and the operation efficiency can be improved.
- The above-mentioned tape dispenser is easy to operate for use. However, the protective tape is used for protecting an article and keeping the article from being damaged during carrying and transportation. Therefore, the protective tape needs a large force to be cut when in use. Besides, the protective tape cannot be aligned with the edge of the article when applying the protective tape, resulting in incomplete protection and being unsightly. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
- The primary object of the present invention is to provide a protective tape dispenser, which can quickly attach the protective tape to the edge of a product, has the advantages of complete protection and increased aesthetics, and can increase the smoothness of operation, so as to achieve the purpose of labor-saving operation and easy force application.
- In order to achieve the aforesaid object, the protective tape dispenser of the present invention comprises a base, a mounting unit, a handle, a guide unit, a cutting unit, a tape pressing unit. The base has an abutting portion at a bottom thereof. The base has a pivot member. The mounting unit is pivotally connected to the base. The mounting unit is configured to mount a protective tape roll. The handle is disposed on the base. The guide unit is disposed on the base. The guide unit includes a tape pressing member and a turning member. The tape pressing member is located between the mounting unit and the turning member. The cutting unit is disposed on the base. The cutting unit includes an operation member and a fixing seat. The operation member is pivotally connected to the pivot member. The operation member has a linking portion and a pressing portion that are located at two sides of the pivot member. A free end of the linking portion is connected to one end of an elastic member. Another end of the elastic member is fixed to the base. The fixing seat is fixed to the base. The fixing seat has a positioning member. The positioning member is connected with a blade holder. The blade holder is movable along the positioning member. The blade holder is provided with a blade. The tape pressing unit is pivotally connected to the abutting portion. The tape pressing unit has a first guide member and a second guide member.
- When the protective tape dispenser provided by the present invention is in use, the protective tape of the protective tape roll is pulled out to pass around the outer side of the turning member along the inner side of the tape pressing member, and is pulled to the outer sides of the first guide member and the second guide member. The technical feature that the turning member extends out of the base can increase the tension of the protective tape and facilitate cutting. By pressing the operation member, the operation member drives the linking member to actuate the blade holder so as to extend or retract the blade, thereby increasing the smoothness of operation. In addition, the guide plate is use to guide the base to quickly align with the edge of a product. The present invention has the advantages of complete protection and increased aesthetics, thereby achieving the purposes of labor-saving operation and easy force application.

The inner diameter of thefirst guide member 61 is greater than the inner diameter of thesecond guide member 62. -
FIG. 7 andFIG. 8 are schematic views in accordance with the preferred embodiment of the present invention when in use. When the user wants to use theprotective tape dispenser 100, theprotective tape roll 21 is first mounted on the mountingunit 20, and then the protective tape of theprotective tape roll 21 is pulled out to pass around the outer side of the turningmember 42 along the inner side of the pressingmember 41. The inner side is defined as facing the inside of thebase 10, and the outer side is defined as facing the outside of thebase 10. After that, the protective tape is pulled to the outer sides of thefirst guide member 61 and thesecond guide member 62. At this time, the user holds theprotective tape dispenser 100 and applies the protective tape to attach to a product. Through the rotation of thefirst guide member 61 and thesecond guide member 62, the protective tape of theprotective tape roll 21 is pulled out smoothly and attached to the product. - The user can move the
stop ring 411 sleeved on thetape pressing member 41 to an appropriate position according to the width of the protective tape of theprotective tape roll 21, so that the protective tape is confined between thefirst side plate 11 and thestop ring 411 to prevent the protective tape from deflecting in the process of adhering to the product. The bottom edge of thefirst side plate 11 is connected to theguide plate 13. Theguide plate 13 can guide the base 10 to align with the product quickly. - When the user wants to use the
blade 58 to cut the protective tape, the user only needs to press thepressing portion 512 of theoperation member 51 to pivot the linkingportion 511 of theoperation member 51 about thepivot member 33. The linkingmember 53 is pivoted to drive the linkingplate 54, so that the linkingplate 54 can push theblade holder 57 and theblade 58 simultaneously, and thecutting edge 581 of theblade 58 extends out of thebase 10. Because the turningmember 42 extends out of thebase 10, the protective tape passing through thetape pressing member 41 will change its angle, thereby turning and increasing the tension of the protective tape. In addition to increasing the flatness of the protective tape attached to the product, thecutting edge 581 of theblade 58 can cut the protective tape easily. At this time, the remaining protective tape of theprotective tape roll 21 stays on the turningmember 42 to facilitate the user to pull the protective tape next time. The elastic force of theelastic members 55 will pull back the linkingportion 511 of theoperation member 51 and simultaneously retract the linkingmember 53, theblade holder 57 and theblade 58 without interfering with the operation of theprotective tape dispenser 100. - It is worth mentioning that the length of the linking
portion 511 is less than the length of thepressing portion 512. When the cuttingunit 50 is in a retracted state, an acute angle is maintained between theoperation member 51 and the linkingmember 53, so that the user can press thepressing portion 512 for theblade 58 to extend quickly. When the cuttingunit 50 is in an extended state, an obtuse angle is maintained between theoperation member 51 and the linkingmember 53. Thereby, when the user releases thepressing portion 512, theblade 58 is quickly retracted through theelastic members 55, so that the operation is labor-saving and easy to apply force, so as to increase the smoothness of the operation. - The angle θ is defined between the
side edge 114 of themiddle portion 111 and thebottom edge 115 of the abuttingportion 112 to maintain the uprightness of theprotective tape dispenser 100 when in use. When the cuttingunit 50 is operated, theblade 58 is kept a distance from the product without contacting the product, so as to maintain the appearance of the product. - Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
