Tape Dispenser System
A tape dispenser including a body with having several functional elements formed thereon, including a cutting edge, an anvil, a guide, finger grips, and a thumb rest. The body also defines an opening for receiving a tape roll therein. The opening may be formed between an outer wall and an inner wall. The dispenser may also include a resilient element that causes the outer wall to contact the tape periphery, even as the tape roll is being depleted. The resilient element also allows for relatively easy loading and unloading of the tape roll without the need to remove or dissemble any parts of the system. A brake also allows the user to stop dispensing tape by pressing the outer wall against the outer periphery of the tape roll.
This application claims the benefit of U.S. Provisional Application No. 61/735,000, filed Dec. 8, 2012. The disclosure of the above application is incorporated herein by reference.
BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention generally relates to dispensers, and more particularly, to a tape dispenser.
2. Description of Related Art
Conventional tape dispensers typically include sharp, linearly arranged cutting edges. Linearly arranged cutting edges can be difficult to use as they require that the tape be pulled at an angle to the cutting edge. A difficulty amplified when the cutting edge is not in an optimum position because the gap between the tape and the cutting edge increases, e.g., as the tape roll is depleted.
Conventional tape dispensers may also include and/or use a plurality of parts to secure the tape roll therein, cut the tape, and make the end of the tape readily available for further dispensing. This complexity adds unnecessarily to the cost of manufacture and assembly of these devices.
SUMMARY OF THE INVENTIONOne example of the present invention is a tape dispenser that provides an efficient and cost effective system and method of using the same for dispensing and cutting tape with a relatively straight pull by the user.
One embodiment of the tape dispenser according to the present invention includes a body structure having a cutting edge and an opening for receiving a tape roll therein. The opening formed between an outer wall and an inner wall. A portion or component of the outer wall urged inward such that it is adjacent to the tape periphery, even as the tape roll is being depleted. The body, including the outer wall and the inner wall may be formed as a single unitary structure; that is, the system may be formed as an integral structure consisting of only one part or component.
The tape dispenser may include one or more finger grips, e.g., formed on a portion of the inner wall, and a recessed thumb positioner, e.g., formed on a portion of the outer wall, for ergonomic and comfortable handling by the user.
The tape dispenser may also include a feature to actuate a braking force by the user by applying a squeezing action. This braking action may slow or stop the rotation of the tape roll for providing desired cut tape length. The tape dispenser may also include a feature that inhibits tape roll rotation, thus keeping the end of the tape in location or position for future use.
The tape dispenser may also provide for easy location of the end of the tape. The tape dispenser allowing the tape to “stand up” (e.g., the free end of the tape does not adhere to any structure or surface of the system) after being cut or allowing it to “lie down” and stick to an anvil for future use. The anvil feature may be configured so as to be shorter in length than the width of the tape in order to facilitate easy access to the side of the end of the tape by the user.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
The above, as well as other advantages of the present invention, will become readily apparent to those skilled in the art from the following detailed description of the preferred embodiment when considered in the light of the accompanying drawings in which:

The description and drawings serve to enable one skilled in the art to make and use the invention, and are not intended to limit the scope of the invention in any manner.

Referring to the Figures generally, and specifically to

In one example of the present invention, the upper portion 14b of the outer wall 14 is an inwardly biased resilient member. As illustrated in
Since the upper portion 14b in the above example is formed of a resilient material, the upper portion 14b functions as a preloaded spring arm, allowing at least partial flexion of the outer wall 14 relative to the inner wall 16, especially in the area of the free end 14c and areas proximate thereto. Furthermore, the resiliency of the outer wall 14, including the upper portion 14b, inwardly bias the upper portion 14b of the outer wall 14 towards the inner wall 16, such that the outer wall 14 maintains, or attempts to maintain, contact with the outer periphery of the tape roll, even as the tape is withdrawn and the tape roll is depleted. Further, depending on the desired inwardly biasing force, the initial location; i.e., before the tape roll 36 is placed in the cavity 18, of the upper portion 14b may vary. For example, given that upper portion 14b of the outer wall 14b is formed of a resilient material, when the upper portion 14b is initially placed or molded in position next to the inner wall 16 it requires a greater force to pull or deflect the upper portion 14b and correspondingly the free end 14c outward to a point past the outer periphery of the tape roll 36. Whereby the force generated on the tape roll 36, as the upper portion 14b attempts to “spring back” to its original position, will also be greater. Accordingly, with the present example, there is a necessary balancing of the force applied recognizing that as the tape 34 is withdrawn and the tape roll 36 is depleted the force will gradually reduce.
In accordance with an aspect of the present invention, an inwardly extending protuberance may be formed or provided on an underside surface 14d of the outer wall 14. In this manner, the cavity 18 may include a first portion or area having a first distance between the outer wall 14 and the inner wall 16 and a second portion or area having a second distance formed between the protuberance and the inner wall 16. By way of a non-limiting example, the second distance may be less than the first distance. Additionally, or alternatively, the dispenser 10 can be initially formed (e.g., via injection molding) to include a taper in the volume of the cavity 18 as it extends from the lower portion 14a towards the free end 14c of the outer wall 14.

In practice, use of the dispenser 10 is fairly simple and straightforward. To insert the tape roll 36 into the system, the outer wall 14 is pulled outwardly away from the inner wall 16. In this manner, the retainer 38 does not block lateral placement of the tape roll 36 onto the inner wall 16.
To dispense the tape 34, the free end 32 of the tape 34 is pulled through the aperture 48 between the guide 14e and the anvil 28. To cut the tape 34, it is placed against the cutting edge 24 and cut, in the conventional manner, by the plurality of teeth 24a. At this point, the free end 32 of the tape can either remain unattached to any surface, including the anvil 28, or can be placed onto the anvil 28. In either scenario, the user can easily find the free end 32 of the tape 34 without having to search and scrape the tape roll 36.
Because the dispenser 10 can be used to dispense long lengths of tape (e.g., blocking off surfaces and borders for painting purposes), there is provided a brake system to stop the dispensing of the tape when desired by the user. Referring to specifically to
