The present invention generally relates to an improved structure of a cutting opening of an adhesive tape dispenser, wherein the cutting opening that serves to cut off an adhesive tape contained in the adhesive tape dispenser has an end forming a pivotal joint holed seat that rotatably couples a cutter that also serves as a cover and that has a bottom from which an extension board extends to a middle portion of the cutting opening to define an enlarged slot, whereby after the adhesive tape is withdrawn from a rotatable support of the dispenser body and cut off by the cutter in the cutting opening, the adhesive tape may follow the closing operation of the cover for storage to be received into the hollow slot so as to meet the need of safety and practicability of operation of the adhesive tape dispenser.
A regular adhesive tape dispenser is constructed to have a fixed base to be positioned on a desktop. A conventional portable adhesive tape dispenser is often of an open structure, which comprises a board based main body in a two-piece integrated configuration having a middle section connected with a flat board to thereby form a U-shaped structure after bending. The middle section flat board has an end forming integrated toothed cutting edge. Opposite surfaces of the U shape are respectively provided with halves of mated projection and recess fastening structure that forms a combined axle serving as a center of a roll of adhesive tape. The adhesive tape, after being unwound and withdrawn, is cut off by the cutting edge. Since the conventional portable adhesive tape dispenser has a side-open configuration and the cutting edge of cutting off the adhesive tape is exposed, the adhesive tape and the cutting edge are both not properly enclosed and protected and are easily susceptible to external contamination or staining with contaminants and may easily hurt a user by accident impact, so that it does not meet the need of safety and sanitary. A conventional portable adhesive tape dispenser that features complete enclosure and easy cutting operation is shown in
In view of the drawbacks of not suiting the needs of safety of continuous application and convenient operation in practical operation of cutting and reception of adhesive tape with the existing structure of conventional portable adhesive tape dispensers, the present invention aims to provide an adhesive tape dispenser having a cutting opening, wherein an extension board below a bottom of the cutting opening is extended to a middle portion of the cutting opening to define a properly enlarged slot to facilitate withdrawal and application of the adhesive tape and wherein when a cutter is closed for storage, the adhesive tape is moved in synchronization therewith to be received into the slot, whereby the various inconveniences and drawbacks of the existing adhesive tape dispensers in respect of reception and application thereof can be improved and overcome.
The primary objective of the present invention is to provide an adhesive tape dispenser that has a top forming a cutting opening and the cutting opening has a bottom that is connected to an extension board that extends to a middle portion of the cutting opening to thereby define an enlarged slot with which sanitary and safety of the adhesive tape realized by being enclosed can be achieved by the closing and storage of a cutter, whereby a convenient and practicable effect of synchronous safety is provided for application, cutting, and reception of the adhesive tape.
The foregoing objectives and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.
Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.
The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
The present invention provides an adhesive tape dispenser having a cutting opening that is improved to allow un-dispensed adhesive tape to move with a tape cutter for easy storage after cutting of the tape has been performed. Referring to
Besides being of a length greater than 49% of the connected segment of the adhesive tape length, to facilitate practical reception of the adhesive tape in a curved and guided manner, the reception slot 18 can be selectively modified to form a rack 19 at the end of the slot 18 adjacent to the extension board 17, as shown in
For the applications of the various embodiments of the present invention that illustrate cutting and reception of the adhesive tape, through controlling the extension length of the extension board 17 from the bottom of the pivotal joint holed seat 13 of the cutting opening 12, the slot 18 is made greater than 49% of the length of the connection surface of the segment of the adhesive tape between points A, B (a too small slot opening preventing the reception of the tape), whereby the adhesive tape segment may follow the closing of the cutter 14 onto the interior of the body 10 to be simply received in the hollow slot 18 of the cutting opening 12, so that the rotation of the cutter 14 is not interfered with and with the assistance provided by curving and guiding of tape realized by the rack 19 at a free end of the extension board 17, the reception and storage of the adhesive tape segment is made smooth. The rack 19 can be formed as a board or a rounded bar to serve as a banner against curving of the inner side of the received adhesive tape segment, so that the adhesive tape segment is forced to naturally form an S-shape of curve for reception, effectively shrinking a space that the adhesive tape swings and thus better suiting the need of safe reception. For all the variety of embodiments, the cutting opening is made to form an enlarged slot 18 to ensure a sufficient hollow space of the adhesive tape segment with respect to a curved surface of the cutter 14 when the adhesive tape segment is being withdrawn for cutting off (an excessively large slot affecting a handling space for withdrawal of the adhesive tape and thus making the withdrawal operation inconvenient), to facilitate the withdrawal of the adhesive tape and eliminate the problem of inconvenient withdrawal and cutting. Further, with the enlargement of the slot 18, the assembling and withdrawal of the adhesive tape body 20 are made convenient, without affecting the portability of the adhesive tape, but still maintaining the safe and sanitary of the adhesive tape in a received and enclosed form, helping preserving integral and aesthetic appearance of the adhesive tape dispenser and realizing the efficacy and purposes of safe and sanitary reception and use. The simple structure of the cutting opening and the synchronous reception of the adhesive tape that provided in accordance with the present invention have never been available in all types of portable adhesive tape dispensers and illustrate a novel creation in the structure of adhesive tape dispensers.
To summarize, the improved structure of the cutting opening of an adhesive tape dispenser in accordance with the present invention uses the enlarged slot that is provided inside the cutting opening and the arrangement of the extension board to simplify the assembling of the adhesive tape roll and also facilitate the withdrawal and cutting of the adhesive tape. Further, the present invention allows for a single hand operation of synchronously curving and receiving of the adhesive tape after the adhesive tape has been cut off, so as to ensure the practicability of safe and convenient withdrawal and reception of the adhesive tape.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
