DETAILED DESCRIPTION OF THE INVENTION

(31) 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 invention, 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 invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined only by the claims and equivalents thereof.

(32) Embodiments of the present invention provide improved twist-tie dispenser refills.

(33) One embodiment twist-tie dispenser refill 100 includes a base 101 and a twist-tie cluster 120, which are shown in FIGS. 1-11. The base 101 includes a generally U-shaped top portion 102 and a rear portion 107. The top portion 102 includes a top 103 interconnecting a front 104 and a rear 105, which form an opening 106 therebetween. Preferably, the front 104 has a generally concave portion, which is shown in FIG. 5. The rear portion 107 extends downward from the rear 105 of the top portion 102, and the rear portion 107 includes a bottom 108. The base 101 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 base 101 could also be made of corrugated cardboard or any other suitable material.

(34) The twist-tie cluster 120 includes a plurality of twist-ties interconnected by a connecting member 121 such as an adhesive proximate a top portion 122 of the cluster. The top portion 122 and a dispense portion 124 are separated by a perforated portion 123, which allows for individual twist-ties of the dispense portion 124 to be easily dispensed therefrom, leaving portions of the twist-ties in the top portion 122, proximate between the connecting member 121 and the perforated portion 123.

(35) The generally U-shaped top portion 102 of the base 101 is configured and arranged to receive within the opening 106 the top portion 122 of the twist-tie cluster 120, which may be friction fit within the generally U-shaped top portion 122 and/or otherwise secured therein with a securing member such as an adhesive, at least one staple, at least one rivet, or the like so that the base 101 is in effect integral with the twist-tie cluster 120. The base is preferably somewhat elastic or flexible in that at least one of the top 103 and the front 104 can be moved relative to the rear 105 to receive the top portion 122 of the twist-tie cluster 120. The generally concave portion of the front 104 assists with the friction fit. A bottom portion of the twist-tie cluster 120, which is a plurality of twist-ties that are not connected, is the dispense portion 124 that is exposed proximate at least a front of the base 101 to allow a user to take one of the twist-ties.

(36) In another embodiment twist-tie dispenser refill 100, as shown in FIG. 12, a rear surface of the base 101 could include a mounting member comprising a top extension 110a and a bottom extension 110b configured and arranged to receive a mounting plate 113, which is operatively connected to a mounting structure such as a plastic bag dispenser. The base 101 could be slid onto the mounting plate 113 with the top and bottom extensions 110a, 110b receiving the mounting plate 113. Also shown in FIG. 12, the base 101 could also include an optional bottom portion or extension 109 extending outward from the bottom 108 to provide protection to the bottom of the twist-tie cluster 120.

(37) In another embodiment twist-tie dispenser refill 100, as shown in FIG. 13, the base 101 could also include a securing mechanism 115 with a stop 116 proximate one side and a lock mechanism 117 proximate the opposing side so that the refill cannot be easily removed from the mounting plate 113. The mounting plate 113 is inserted between the top and bottom extensions 110a and 110b proximate the lock mechanism 117 and slid through the channels formed by the top and bottom extensions 110a and 110b until the mounting plate 113 is positioned between the stop 116 and the lock mechanism 117. After the lock mechanism 117 is in a lock position, the lock mechanism 117 must be released to slide the refill off the mounting plate 113. This provides a more secure refill and deters theft of the refill.

(38) In another embodiment twist-tie dispenser refill, as shown in FIG. 14, the base 101 could include alternative types of optional mounting members such as mounting members 111 operatively connected to the top of the base 101 and configured and arranged to receive a mounting plate 113, or mounting members 112 operatively connected to the bottom portion, or extension 109 configured and arranged to receive a mounting plate 113. One or more of these types of mounting members could be used, and it is recognized that other types of mounting members could be used depending upon the desired mounting orientation of the base. For example, mounting members proximate the top of the base could be used if it is desired for the base to hang downward relative to a mounting plate or surface, mounting members proximate the bottom of the base could be used if it is desired for the base to extend upward relative to a mounting plate or surface (e.g., table), and mounting members proximate the rear of the base could be used.

(39) In another embodiment, a rod (not shown) could be inserted through a bore 106a formed between the top 103 of the top portion 102 and the connected top portion 122 of the twist-tie cluster 120. The rod could be configured and arranged to lock onto the mounting structure to secure the refill thereto.

(40) Rather than simply refilling the twist-tie cluster, the present invention includes a base that is in effect integral with a twist-tie cluster. This has numerous benefits including biodegradable components, lower cost because a heavy plastic receiver is eliminated, cleaner appearance of the base because it is replaced with a new refill including a new base, the ability to match advertising on the base with advertising on the twist-ties, etc.

(41) FIGS. 15-19 illustrate another version of the base 101 for a twist-tie dispenser refill. The base 101 of the dispenser refill shown in FIGS. 15-19 includes an alternative embodiment of a mounting member 112 used for mounting the base 101 to a fixture 200. The mounting member 112, depicted, includes at least one extension 150. The extension 150 protrudes outwardly from the rear portion 107 of the base 101. The extension 150 defines a hook-like configuration and is configured to receive elongate, rod-like mounting structures 202 of a fixture 200 to which the twist-tie dispenser refill 100 is going to be mounted. Two examples of fixtures 200, 300 to which the base 101 may be mounted that include elongate rod-like mounting structures 202 are shown in FIGS. 27 and 28.

(42) The at least one extension 150 can include a plurality of extensions 150 as shown in the depicted version of the base 101. In certain embodiments, the at least one extension 150 can include multiple rows of extensions 150 such as the version shown such that the twist-tie dispenser refill 100 can be mounted to fixtures that have parallel elongate rod-like mounting structures 202. The examples of fixtures 200, 300 shown in FIGS. 27 and 28 each include two parallel rod-like mounting structures 202. The rows of the extensions 150 of the base 101 are spaced apart in accordance with the spacing of the rod-like structures 202. Even though shown as including two parallel rod-like mounting structures 202, more or less rod-like mounting structures 202 may be provided on the fixtures 200, 300. According to one example embodiment, the rod-like structures 202 may be 3/16 in diameter and the spacing between the two rows of the rod-like mounting structures 202 may be 1.

(43) According to the depicted embodiment, the hook-like configuration defined by each extension 150 defines a pocket 152 formed by an upper stop portion 154 and a vertical retention portion 156. In the depicted embodiment of the base 101, the entrance of the pocket 152 is blocked by a flexible cantilever tab 158. The cantilever tab 158 is configured such that it is to be elastically flexed out of the way when receiving the elongate rod-like mounting structure 202 into the pocket 152. Once the rod 202 is past the cantilever 158 and enters the pocket 152 to abut the upper stop portion 154, the cantilever 158 flexes back into original position. The flexible cantilever 158 is configured to prevent or limit removal of the rod 202 from the mounting member 112 of the twist-tie dispenser refill 100. Although depicted in the present embodiment as including cantilever members 158, in other embodiments, the base 101 may be configured with just extensions 150 that do not have opposing cantilever members 158 to prevent removal. In such embodiments (an example of which is shown in FIGS. 20-25), the bases 101 of the twist-tie dispenser refills 100 may simply be hung from the rod-like structures 202 of the fixtures 200, 300. In the embodiment of the twist-tie dispenser refill 100 shown in FIGS. 20-25, the twist-tie dispenser refill 100 can simply be removed by lifting the twist-tie dispenser refill 100 from the rod(s) 202 without having to manipulate any cantilever members.

(44) In certain embodiments, the rod-like mounting structures 202 may be received within the pockets 152 formed by the extensions 150 via a snap-fit interlock. In such embodiments, the vertical retention portion 156 of the extension 150 may define a tab 160 that acts to retain the rod 202 in the pocket 152. In such an embodiment, when the rod 202 is entering the pocket 152 formed by the extension 150, the rod 202 contacts the tab 160 and flexes out the vertical retention portion 156. After the rod 202 clears the tab 160, the vertical retention portion 156 can flex back to snap in the rod 202 within the pocket 152. The tabs 160 are shown in the version of the twist-tie dispenser refill 100 illustrated in FIGS. 20-25.

(45) FIG. 26 depicts a converter clip structure 400 that can be removably attached to a preexisting twist-tie dispenser refill to convert it to a version that provides a similar mounting arrangement such as those shown in FIGS. 15-25. The converter clip 400 may define extension(s) 150 and/or cantilever(s) 158 similar to those found in the mounting members 112 of the twist-tie dispenser refill 100 of FIGS. 15-25. The converter clip 400 is configured to be snapped over the U-shaped top portion 102 of the base 101 of a preexisting twist-tie dispenser refill 100 which does not normally include extensions protruding from the rear portion 107 of the base 101.

(46) Still referring to FIG. 26, the converter clip 400 may define a generally L-shaped body 402 including a top horizontal portion 404 and a vertical portion 406 that extends down from the top horizontal portion 404. The vertical portion 406 includes the mounting member(s) 112 for attachment to fixtures such as fixtures 200, 300. The top horizontal portion 404 may define a downwardly hanging lip 408 at a front edge thereof. The converter clip 400 may also define another lip 410 at an inner side of the vertical portion 406 that is configured to oppose the lip 408 at the front edge. The two opposing lips 408, 410 may be used to snap-fit the converter clip structure 400 to the U-shaped top portion 102 of the base 101. For example, the lips 408, 410 may engage flanges defined at an outer perimeter of the top 103 of the top portion 102 of the base 101 of a preexisting twist-tie dispenser refill 100. Such flanges may be defined at the front and back edges of the top 103 of the top portion 102 for snap-fitting with the lips 408, 410 of the converter clip 400.

(47) As noted above, the converter clip 400 may define mounting members 112 such as those shown on twist-tie dispenser refills 100 of FIGS. 15-25, wherein the mounting members 112 are provided by extensions 150. The extensions 150 defined by the converter clip 400 may be provided in parallel rows that match the spacing of the rod-like structures 202 that may be found on the fixtures 200, 300. In certain embodiments of the converter clip 400, the parallel extensions 150 may extend the entire width of the converter clip 400.

(48) The above specification, examples, and data provide a complete description of the manufacture and use of the composition of embodiments of the invention. Although specific embodiments have been illustrated and described herein, it will be appreciated by those of ordinary skill in the art that any arrangement, which is calculated to achieve the same purpose, may be substituted for the specific embodiment shown. This application is intended to cover any adaptations or variations of the invention. Therefore, it is manifestly intended that this invention be limited only by the claims and the equivalents thereof.
