The present disclosure relates generally to twist-tie dispensers and methods of use.
There are many uses for twist-ties. In a grocery store, for example, consumers commonly place produce items, bakery items, bulk food items, and the like in bags and use twist-ties to temporarily close the bags. In such uses, sanitary conditions are very important and, therefore, consideration should be given to the manner in which the twist-ties are dispensed. Further, spillage of twist-ties is a concern for safety reasons among others. Quick and cost-effective refill or replacement of the twist-ties or the dispensers thereof is also advantageous.
For the reasons stated above and for other reasons stated below, which will become apparent to those skilled in the art upon reading and understanding the present specification, there is a need in the art for an improved twist-tie dispenser.
The above-mentioned problems associated with prior devices are addressed by embodiments of the present invention and will be understood by reading and understanding the present specification. The following summary is made by way of example and not by way of limitation. It is merely provided to aid the reader in understanding some of the aspects of the invention.
In one embodiment, the twist-tie dispenser is configured as a disposable product, wherein the dispenser can be thrown away or disposed of once the twist-tie cluster is spent. The twist-tie dispenser comprises a base and a twist-tie cluster attached to the base. The base includes a top portion, which may be generally U-shaped and form a pocket that is for receiving the twist-tie cluster. The base also includes a rear portion or wall that defines mounting members used for mounting the base to a fixture.
According to one example embodiment, the mounting members may be defined by hook-like extensions that protrude from the rear wall of the base, wherein the hook-like extensions are configured to receive elongate, rod-like mounting structures of a fixture to which the disposable twist-tie dispenser is to be mounted. According to one example, the hook-like extensions may fit over the elongate, rod-like mounting structures of the fixture. In addition to the hook-like extensions, the rear wall of the base may define a flexible portion that is used for latching and unlatching the dispenser to the fixture.
The flexible portion acts as a cantilever. In some embodiments, the flexible portion defines ramped tabs with latching surfaces that oppose and cooperate with upper stop surfaces formed by the hook-like extensions for latching the dispenser to the fixture. When the twist-tie cluster is spent and the dispenser needs to be removed and replaced, the flexible portion may be elastically flexed toward the front of the dispenser to clear the latching surfaces from the rod-like mounting structures of the fixture. In this manner, the dispenser can be lifted off the fixture.
According to another aspect of the disclosure, a twist-tie dispenser comprises a base including a top portion defining a twist-tie cluster mounting surface, a rear wall extending downward from the top portion, and an open front. A latching structure configured for removably mounting the base to a fixture including at least one rod-like mounting structure is defined at least in part by a first hook-like extension protruding from the rear wall of the base, the first hook-like extension defining a pocket formed by an upper stop surface and a vertical retention surface, the latching structure also defined at least in part by a flexible portion of the rear wall that is configured to elastically deflect through a cut-out provided on the rear wall in a direction from the rear wall toward the open front when the rod-like mounting structure of the fixture is inserted into the pocket of the first hook-like extension, the flexible portion also defining a lower stop surface that opposes the upper stop surface of the first hook-like extension when the rod-like mounting structure is within the pocket of the first hook-like extension and is captured between the lower stop surface and the upper stop surface. As seen in
According to another aspect of the disclosure, the twist-tie dispenser includes the twist-tie cluster integrally mounted to the top portion of the base, and the dispenser including the twist-tie cluster is mounted and removed from the fixture as an integral disposable unit.
According to yet another aspect, the disclosure is directed to a method of using a twist-tie dispenser, the method comprising providing a twist-tie dispenser comprising a base including a top portion defining a twist-tie cluster mounting surface, a rear wall extending downward from the top portion, and an open front, the dispenser further comprising a latching structure configured for removably mounting the base to a fixture including at least one rod-like mounting structure, the latching structure defined at least in part by a first hook-like extension protruding from the rear wall of the base, the first hook-like extension defining a pocket formed by an upper stop surface and a vertical retention surface, the latching structure also defined at least in part by a flexible portion of the rear wall that is configured to elastically deflect through a cut-out provided on the rear wall in a direction from the rear wall toward the open front when the rod-like mounting structure of the fixture is inserted into the pocket of the first hook-like extension, the flexible portion also defining a lower stop surface that opposes the upper stop surface of the first hook-like extension when the rod-like mounting structure is within the pocket and is captured between the lower stop surface and the upper stop surface, slidably inserting the rod-like structure of the fixture into the pocket of the first hook-like extension until abutting the upper stop surface, and while slidably inserting the rod-like structure of the fixture into the pocket of the first hook-like extension, deflecting the flexible portion of the rear wall through the cut-out provided on the rear wall until the rod-like structure is captured between the upper stop surface of the first hook-like extension and the lower stop surface defined by the flexible portion.
The method may further comprise removing the twist-tie dispenser from the fixture by re-deflecting the flexible portion toward the open front through the cut-out provided on the rear wall until the rod-like structure clears the lower stop surface and slidably lifting the base upward relative to the fixture.
The inventive aspects of the present disclosure can be more easily understood, and further advantages and uses thereof can be more readily apparent, when considered in view of the detailed description and the following Figures in which:
In accordance with common practice, the various described features are not drawn to scale but are drawn to emphasize specific inventive features relevant to the present disclosure. Reference characters denote like elements throughout the Figures and the text.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration, embodiments in which the inventions may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the inventive features, and it is to be understood that other embodiments may be utilized and mechanical changes may be made without departing from the spirit and scope of the present disclosure. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present inventive features are defined only by the claims and equivalents thereof
Embodiments of the present disclosure provide improved twist-tie dispensers.
According to one embodiment, the twist-tie dispenser 10 is configured as a disposable device, wherein the entire dispenser 10 can be removed from a fixture 12 at a customer location such as a grocery store and thrown away or disposed of once a twist-tie cluster 14 is spent. In such an embodiment, the twist-tie cluster 14 may be provided with/attached to the dispenser 10 as an integral unit. The twist-tie cluster 14 may be attached to the dispenser 10 in a variety of ways known in the art including via adhesives. Once the twist-ties of the cluster 14 are used and the entire cluster 14 is spent, the entire dispenser 10, along with the portion of the cluster 14 that has adhesively been attached to the dispenser 10, can be disposed. An example of a twist-tie cluster 14 that can be fixed to any of the dispensers discussed in the present application is shown in
Referring to
As shown in
The base 16 could be made of extruded plastic and optionally be at least partially covered with paper, which could include graphics such as logos, trademarks, advertising, and the like.
The twist-tie cluster 14 that is provided as part of the dispenser 10 may include a plurality of twist-ties that are attached to a mounting surface 22 defined by the top portion 18 of the base 16 via, for example, adhesive. Other methods of attaching the twist-tie cluster 14 to the base 16 are also contemplated. For example, the base 16 and the twist-tie cluster 14 may be secured with a securing member selected from the group consisting of an adhesive, at least one staple, and at least one rivet.
In assembling the dispenser 10, a top portion of the twist-tie cluster 14 is received by a pocket 24 formed by the U-shaped top portion 18 of the base 16. The top portion of the cluster 14 is adhered to an inside mounting surface 22 of a top wall 23 of the U-shaped top portion 18 of the base 16. A bottom portion of the twist-tie cluster 14, which is formed from a plurality of separated twist-ties, hangs down from the U-shaped top portion 18 of the base 16 and is exposed to the users from an open front 26 of the base 16. A user can tear off one of the twist-ties by accessing it from the open front 26.
As noted above, rather than simply refilling the twist-tie cluster 14, the dispenser 10 of the present disclosure includes a base 16 that is in effect integral with a twist-tie cluster 14. This has numerous benefits including provision of biodegradable components, lower cost by elimination of a heavy plastic receiver, cleaner appearance of the base 16 due to periodic disposal and replacement with a new base 16, the ability to match advertising on the base 16 with advertising on the twist-ties, etc.

The at least one extension 36 can include a plurality of extensions 36 as shown in the depicted version of the base 16. In certain embodiments, the at least one extension 36 can include multiple rows of extensions 36 (as in the version shown) such that the twist-tie dispenser 10 can be mounted to a fixture 12 that has multiple parallel elongate rod-like mounting structures 30.
In the embodiment depicted in
According to the depicted embodiment, the hook-like configuration defined by each extension 36 defines a pocket 42 formed by an upper stop surface 44 and a vertical retention surface 46.

The flexible portion 48 acts as a cantilever. The flexible portion 48 may define at least one ramped tab 50. The ramped configuration of the tab 50 provides deflection to the flexible portion 48 as a rod-like structure 30 of the fixture 12 contacts the tab 50. The ramped tab 50 defines a latching surface 52 (also called a lower stop surface 52) that opposes and cooperates with the upper stop surface 44 formed by one of the hook-like extensions 36 for latching the dispenser 10 to the fixture 12. In the depicted version of the dispenser 10, the flexible portion 48 is provided at the center of the two extensions 36 of the lower row 38, and two ramped tabs 50 are provided on the flexible portion 48 of the base 16, each one configured to cooperate with a corresponding extension 36 on the lower row 38. As noted above, the ramps facilitate slidable latching of the dispenser 10 to the fixture 12. The rod-like mounting structures 30 of the fixture 12 can ride along the ramped tabs 50 and elastically deflect the flexible portion 48 as the rod-like mounting structures 30 enter the pockets 42 of the hook-like extensions 36.
When mounting the dispenser 10 to the fixture 12, the cantilevered flexible portion 48 is contacted and elastically flexed out of the way when receiving the elongate rod-like mounting structure 30 into the pockets 42 of the hook-like extensions 36. Once the rod 30 is passed over the ramped tab 50 of the cantilever 48 and enters the pocket 42 to abut the upper stop surface 44, the cantilever 48 flexes back to its original position. The latching or lower stop surfaces 52 of the ramped tabs 50 are configured to cooperate with the upper stop surfaces 44 of the extensions 36 to capture and prevent or limit removal of the rod 30 from the base 16 of the twist-tie dispenser 10.
When the twist-tie cluster 14 is spent and the dispenser 10 needs to be removed and replaced, the flexible portion 48 may be elastically flexed toward the open front 26 of the dispenser base 16 to clear the latching surfaces 52 from the rod-like mounting structures 30 of the fixture 12. In this manner, the dispenser 10 can be lifted off the fixture 12.
The extension 36 provided at the upper row 40 provides stability to the base 16 when mounted on the fixture 12 by cooperating with the other rod-like mounting structure 30 of the fixture 12 that is parallel to the lower rod-like mounting structure 30. In certain embodiment, the upper extension 36 may not be needed.
It should be noted that the mounting arrangement shown in
Thus, the hook-like extensions 236 and the flexible portion 248 may provide a conversion structure for converting preexisting non-disposable dispensers to disposable dispensers 210 with minor modification.
