Patent Application
20150053342
The present invention relates to roll-type adhesive tape (variable length, reusable/refillable) dispensers (no pre-cut lengths of tape) and, more particularly, to hand held tape dispensers that can be manually operated with the use of only one hand to dispense, apply and cut a desired variable length of adhesive tape without the operator having to touch the tape.
An adhesive tape dispenser is a device that holds a roll of adhesive tape and has a cutter mechanism at one end to sever the tape from the roll. The design and construction of adhesive tape dispensers vary widely based on the type of tape they dispense and the nature of use. One of the most common of such devices are clear adhesive tape, also commonly referred to as “cellophane” or “scotch” tape, dispensers designed for general household and/or light duty office use. These types of dispensers are commonly made of plastic, are small enough so that the dispenser, with the tape in it, can be easily picked up and manipulated near the point of application, and are intended to be either disposable or refillable depending upon the user's discretion. A further characteristic of conventional cellophane tape dispensers is that they require two-handed “pull and tear” operation. In other words, the user must hold the dispenser with one hand while grasping the adhesive tape with the other hand, then pulling out a desired length of tape from the roll, and tearing or severing the tape using the dispenser's cutting mechanism. The torn off length of tape is then manipulated, often with both hands, in order to apply it at the proper location on the surface of the object being taped. Because the tape is sticky, the user requires a certain degree of dexterity in order to apply the tape properly and without the tape sticking to itself. Oftentimes, the user's fingerprints are left visible on the otherwise clear tape, and if the tape has become stuck to itself it may need to be discarded. Further, dispensing the correct length of tape requires a certain amount of guesswork, either causing wastage when the length cut is greater than the length required, or duplication of effort if the length cut off from the roll is too short.
Over the years, there have been many attempts to improve on the design of conventional adhesive tape dispensers in order to address these and other drawbacks, however, there still remains a need for improvement in this field.
Based on the disadvantages and limitations described above in the prior art devices for roll type adhesive tape dispensers, it was determined that improvements needed to be made to achieve a combination dispenser and applicator designed for general household and/or light duty office use which would allow for one-handed use, and accurate dispensing and application of the desired length of tape directly on the surface to be applied without the operator needing to touch the tape.

As used in the claims and the specification, the following terms have the following definitions:
The term “tape dispenser/applicator” as used herein means a device that both dispenses tape and functions to assist a user in applying the tape to a surface or substrate.
The term “serrations” as used herein means a formation of notches, grooves, teeth and/or other surface indentations or formations.
The language used in the claims and the written description is to only have its plain and ordinary meaning, except as explicitly defined above. Such plain and ordinary meaning is inclusive of all consistent dictionary definitions from the most recently published (as of the filing date of this application) general purpose Webster's dictionaries and Random House dictionaries.
Referring now to the drawings, an adhesive tape dispenser/applicator 100 according to one embodiment of the present invention is illustrated generally in
and come in different translucent, transparent, or solid colors and shapes. The housing 101 may optionally include a circular through passageway 103a on the axis of spool holder 103 to further facilitate manipulation of the dispenser/applicator 100.
Referring now also to
Mounted inside and/or to the housing 101 is a tape applicator/cutter assembly 112. The tape applicator/cutter assembly 112 includes a cutter 113, an applicator roller 114 and a guide roller 115. The applicator roller 114 is positioned to pressingly contact the non-adhesive side 102b of the tape 102 against the application surface or substrate. The guide roller 115 is positioned to guide the advancement of the adhesive side 102a of the tape 102 as the tape is dispensed from the roll. The guide roller 115 is rotatably mounted on an axis 117 and may have a plurality of longitudinal serrations 118 extending along the circumference of the guide roller 115 for facilitating dispensing of tape from the dispenser/applicator 100. The precise size, shape and positioning of the serrations 118 may vary, it being important only that they are shaped and formed as needed to limit the amount of contact area between the guide roller 115 and the adhesive side 102a of the tape 102 to that needed to smoothly guide advancement of the tape while not allowing the tape to stick to the roller 115 so as to cause any binding of movement. In one embodiment shown in
The tape applicator/cutter assembly 112 further has a finger actuated button 120 with a spring release 121 and a button guide 122 mounting the button 120 and applicator roller 114. The button guide 122 guides the movement of the button 120 and applicator roller 114 relative to the housing 101. Preferably, the button guide 122 provides for a smooth linear guiding movement of the finger actuated button 120. The finger actuated button 120 is positioned towards the forward end 106 of the housing 101 along the top surface 104. The finger actuated button 120 is configured to actuate relative movement between the applicator roller 114 and the guide roller 115 prior to the cutter 113 severing a length of tape from the roll. As seen in
Returning to
The method for single-handedly dispensing a desired length of pressure sensitive one-sided adhesive tape from a roll and applying the tape to a substrate may be performed as follows. The user grasps the tape dispenser such as 100 in one hand with the index finger on the finger button and single-handedly places the applicator roller 114 flat on the substrate. While still grasping the tape dispenser in one hand with the index finger on the finger button 120, the user moves the tape dispenser 100 rearwardly across the substrate so as to simultaneously dispense tape 102 from the roll and apply the pressure sensitive adhesive tape to the substrate. The rearward movement may be accomplished by a sliding or gliding movement of the tape dispenser 100. The user then stops the rearward movement of the tape dispenser 100 when a desired length of tape 102 has been applied to the substrate. Once the rearward movement is stopped, the user actuates the finger button 120 to move upwardly to initiate cutting of the applied length of tape 102 from the roll with the cutter 113.
The above described steps are each performed single-handedly, and without the user ever having to directly touch the tape. In addition, there is no need to pre-measure or estimate the length of tape needed as the desired length of tape is dispensed as it is being applied to the substrate. Accordingly, less tape is wasted and the tape is stored and applied in a more sanitary manner. In addition the applied tape is not made unsightly because the user's fingerprints are never left visible on otherwise transparent clear tape. Moreover, the tape dispenser/applicator is designed so that the amount of exposed tape is much less, and can be conveniently stored on a table top or desktop when not in use without any exposed tape touching the support surface.
While at least one embodiment has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that the preferred embodiment has been shown and described and that all changes, equivalents, and modifications that come within the spirit of the inventions defined by following claims are desired to be protected.
