The invention relates to packaging monofilament line. More particularly, the invention relates to a package for a roll of monofilament line with a cutting tool embedded in the package for cutting monofilament line being dispensed from the package.
Monofilament lines are well known in the art and are commonly defined as strings made from a single fiber. Common examples of monofilament lines include, but are not limited to, vegetation trimmer or cutting lines, pulling lines, fishing lines, and utility lines. Such monofilament lines may be made from single component filaments or from multi-component filaments, and may be produced by any of a variety of methods known in the art, including, but not limited to, molding, extruding and/or spinning. Many types of monofilament lines are made from polymeric materials.
Typically, such monofilament lines are packaged in bulk form. That is, typically, the monofilament lines are produced as continuous lines of a single or multi-component filament that are wound or otherwise placed into containers for holding the monofilament lines. One such plastic container or package commonly used for vegetation trimmer line or weed cutting line is known in the industry as a “donut package” due to the general appearance of the monofilament line that is wound within the cavity of the container. The cavity of the package, as well as the monofilament line wound within it, resembles the shape of a donut.
Heretofore, users of flexible wound monofilament line packaged in plastic containers have had to use auxiliary cutting devices such as, for example, knives, scissors, blades, or wire cutters, to cut the line to a desired length. The reliance on such auxiliary cutting devices is undesirable since the user, first, must possess a cutting device suitable for and capable of cutting the monofilament line and, second, must keep the cutting device close at hand or within the proximity of the user to enable the user to cut the line at a time of convenience when needed. In addition, many cutting devices, such as knives or blades, are known to be dangerous to the user due to the exposed sharp edges of these devices.
It is known in the art to attach a monofilament line cutting tool to the container holding the monofilament line to address the foregoing problem. For example, in U.S. Pat. No. 7,908,953 a cutting tool for cutting monofilament line is attached to the package. The cutting tool comprises a base member having a groove adapted to receive the flexible line when the cutting tool is in use and a blade recessed within the groove, the blade being adapted to cut the flexible line when the line is forced into the blade during use of the cutting tool. The cutting tool further includes an arm member in operative relationship with and complementary to the base member, which arm member is capable of producing and applying mechanical advantage in a manner that forces the flexible line received within the groove against the blade to thereby sever the flexible line.
One drawback to attaching the cutting tool to the package not addressed in the '953 patent is that the cutting tool being attached to the exterior of the package lends to the cutting tool being pilfered or easily removed from the exterior of the package at the point of sale. Additionally, if the cutting tool is not attached securely to the package over time the cutting tool may loosen and fall off the package. As such, there is a need for a means for securely attaching the cutting tool to the package that is theft-proof, reliable and easy to manufacture.
In an embodiment, there is provided a package for storing a roll of monofilament line and dispensing a length of monofilament line from the package in combination with a cutting tool embedded in the package for cutting the length of monofilament line from the roll, including a package formed from two opposing clamshell portions made from sheets of film, a recess formed in each of the clamshell portions that collectively form a chamber when said two clamshell portions are in a closed configuration, the chamber configured to store said roll and allow a length of monofilament line to unwind from the roll during dispensing, and a cutting tool at least partially disposed between the two clamshell portions when in the closed configuration configured to attach the cutting tool to the package, wherein at least a portion of the cutting tool is accessible from outside the package for cutting a length of monofilament line being dispensed from the package.

In an embodiment, there is provided a cutting device for cutting a length of monofilament line from a roll of monofilament line line stored in a package, including a body portion that protrudes through an opening in one of two clamshell portions forming the package such that a blade portion disposed on the body portion is exterior to the package, a base portion sandwiched between the two clamshell portions when the clamshell portions are sealed together, and a slotted cavity formed on the main body and disposed exterior of and accessible only from the exterior of the the package, wherein a length of monofilament line is inserted into the cavity and pressed against a blade in the cavity to cut the length of the monofilament line being dispensed from the roll stored in the package.
In an embodiment, there is provided a method of dispensing and cutting a length of monofilament line from a package storing the monofilament line, including the steps of: advancing a length of monofilament line from a roll of monofilament line stored in a compartment formed in the packaged, inserting the monofilament line in the region where the monofilament line is to be cut through a first sidewall of the package into a cavity of a cutting device disposed in a pocket formed in a second opposing sidewall of the package, urging the monofilament line against a blade disposed in the cavity to cut the length of monofilament line from the roll, and removing newly cut ends of the length of monofilament line and the roll of monofilament line from the cavity of the cutting device and back through the opening formed in the first sidewall.
A more complete understanding of the present invention, and the attendant advantages and features thereof, will be more readily understood by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
Referring now to the drawing figures in which like reference designators refer to like elements, there is shown in
In an embodiment, the package 100 may be made of one-piece (clamshell) or two-piece construction, wherein the package 100 includes opposed clamshell portions 110 and 120 that generally form a housing or container defining a cavity 150 for storing flexible wound line M. The opposed clamshell portions 110 and 120 may be thermoformed and cut from pieces of material, or otherwise molded from the same mold and, thereby have the same identical shape and size, or may be cut, molded or thermoformed from different molds and, thereby, not have the same identical shape or size.
In an embodiment, the opposed clamshell portions 110 and 120 may be pivotally attached to a base 130 made from the same or a different material. The opposed clamshell portions 110 and 120 may be integrally molded with the base 130, or if formed as separate pieces, attached to the base 130 using glue, thermal fusing, or other attachments means. The base 130 may have a flat bottom surface 131 that may be positioned on a horizontal surface for supporting the package 100 in a vertical position as illustrated in
The opposed clamshell portions 110 and 120 (reference may be made to
In an embodiment, the opposed clamshell portions 110 and 120 may be affixed or sealed together above the cavity 150 using a plurality of reversible snap-type fasteners 115 or other fastening means including adhesives. The snap-type fasteners 115 illustrated are foamed from a projection 115a in the sidewall 112 that snaps into a complementary dimple 115b formed on the sidewall 122. The reversible snap-type fasteners 115 are disposed above the cavity 150 and spaced to provide maximum sealing effectiveness of the opposing clamshell portions 110 and 120, and yet the consumer can disassemble the package for ease of recycling after using the monofilament line. A looped handle 105 may be formed in the top of the opposing clamshell portions 110 and 120 for transporting the package 100 or hanging it on a display rack in a retail store, etc. The looped handle 105 is formed from cutouts 105a in the clamshell portion 110 and 105b in the clamshell portion 120 (see
It will be appreciated, however, that other forms of packages or containers may be used in conjunction with the concepts of the present invention, and the present invention should not be limited to the embodiments described herein and illustrated in the drawings, the breadth of the invention being determined by the scope and spirit of the attached claims. For example, the package 100 may alternatively be cut, extruded, molded, blow molded, injection molded or thermoformed into any desired container shape or size known in the art. The package 100 may be made from hard plastic, thin plastic, thermoformed plastic, molded plastic, cut plastic, paper, cardboard or even may be made from metal or aluminum or combinations of any of these. Still further, the package 100 may be made so that the monofilament line M contained therein is wound onto a spool, or may be made such that no spool is necessary for the wound line. Alternatively, the package 100 may be made as a loop package. Loop packages typically contain 3 to 50 feet of line. In contrast, spools may be used to hold up to 5 pounds of line. Essentially any size or shape container will be suitable as the package 100 provided it can contain and store flexible wound line M as shown in the drawings. However, in one embodiment, the package 100 is made of non-metal. In another embodiment, the package 100 is made solely of polymeric materials.
Flexible wound line M may be essentially any line known in the art, including but not limited to, vegetation trimmer or cutting line, fishing line, pulling line, utility line, and the like. While it is preferably monofilament line, it will be appreciated that multi-filament lines, e.g., yarns, ropes, etc., may also be included as flexible wound line. Similarly, while the line is preferably polymeric, it will be appreciated that line made from non-polymeric materials, e.g., wire, cable, etc., may also be included as flexible wound line. Still further, tubing or other continuous filaments having a hollow core may also be included as flexible wound line for the purposes of this invention. However, in one embodiment, the present invention is a package 100 containing a flexible wound line that is devoid of filaments having hollow cores. In another embodiment, the present invention is a package 100 containing flexible wound line that is devoid of multi-filaments. And in yet another embodiment, the present invention is a package 100 containing polymeric flexible wound line.
