Abstract

A biodegradable lawn waste collection system is provided. The system generally includes a waste receiver, a shaping insert, and a handle. The waste receiver may comprise a mesh structure having a filling end and a sealing end. The mesh structure may be formed from a biodegradable polymer composition. The shaping insert is configured for removable reception within the filling end of the waste receiver. The shaping insert provides the waste receiver with rigidity and stability when filling the waste receiver with lawn waste. After the waste receiver has been filled with lawn waste, the shaping inert is removed and the filling end is secured, such as by tying a knot. The full waste receiver is then releasably attached to the handle, which enables the full waste receiver to be easily carried or dragged to a desired destination.

Claims

1. A biodegradable lawn waste collection system comprising:

(a) a waste receiver comprising an extruded tubular mesh structure formed from a biodegradable polymer composition, wherein the extruded tubular mesh structure has a pre-receiving configuration having a pre-receiving diameter (D_PR), a pre-receiving width (W_PR), and a pre-receiving volume, and the extruded tubular mesh structure is capable of expanding to a receiving configuration having a receiving diameter (D_R), a receiving width (W_R), wherein the pre-receiving diameter (D_PR) is at least 10 percent of the receiving diameter (D_R), and a receiving volume, the waste receiver including a filling end and a sealing end, wherein the waste receiver is formed with a color selected from the group consisting of;

red, orange, yellow, green, blue, violet, black, and combinations thereof, wherein the color has an L* value that is less than or equal to 60;

(b) a shaping insert configured for removable reception within the waste receiver, wherein the shaping insert has a shaping insert perimeter, a shaping insert proximal end, a shaping insert distal end, and a continuous sidewall extending between the shaping insert proximal end and the shaping insert distal end such that the shaping insert has a tubular configuration;

wherein the shaping insert further comprises a collapsible tube having a spring-coil secured to the collapsible tube, wherein the spring-coil is capable of biasing the collapsible tube from a storage position to an expanded position;

wherein the shaping insert includes a first proximal handle secured to the shaping insert proximal end and a second proximal handle secured to the shaping insert proximal end in direct opposing relationship to the first proximal handle;

wherein the shaping insert further includes a first distal handle secured to the shaping insert distal end and a second distal handle secured to the shaping insert distal end in direct opposing relationship to the first distal handle, and wherein when the collapsible tube is in the storage position, the first distal handle substantially aligns with the first proximal handle and the second distal handle substantially aligns with the second proximal handle,

a first proximal fastening device secured to a portion of the first proximal handle and a first distal fastening device secured to a portion of the first distal handle, wherein the first distal fastening device is configured for cooperative engagement with the first proximal fastening device;

a second proximal fastening device secured to a portion of the second proximal handle and a second distal fastening device secured to a portion of the second distal handle, wherein the second distal fastening device is configured for cooperative engagement with the second proximal fastening device; and

wherein when the first proximal fastening device and first distal fastening device are cooperatively engaged the resiliency of the spring-coil places the first proximal fastening device in shear with the first distal fastening device, and when the second proximal fastening device and second distal fastening device are cooperatively engaged the resiliency of the spring-coil places the second proximal fastening device in shear with the second distal fastening device; and

(c) a handle having at least one attachment port for releasable attachment with the waste receiver.

2. The system of claim 1, wherein the pre-receiving diameter (D_PR) is no more than 40 percent of the receiving diameter (D_R).

3. The system of claim 1, wherein the shaping insert has a circular shaping insert perimeter with a radius that is at least 50 percent greater than the pre-receiving diameter (D_PR).

4. The system of claim 1, wherein the shaping insert has a non-circular shaping insert perimeter selected from the group consisting of triangular, square, and rectangular, wherein the non-circular shaping insert perimeter is formed with rounded corners having a radius of curvature that is less than the pre-receiving diameter (D_PR).

5. The system of claim 1, wherein the shaping insert comprises a collapsible tube having a rounded insertion edge, wherein the rounded insertion edge has a radius of curvature that is at least 50 percent greater than the pre-receiving diameter (D_PR) and is less than 5 times greater than the pre-receiving diameter (D_PR).

6. The system of claim 1, wherein the biodegradable polymer composition comprises polylactic acid.

7. The system of claim 1, wherein the sealing end is heat staked such that the waste receiver is sealed at the sealing end.

8. The system of claim 1, wherein the handle includes at least two attachment ports for releasable attachment with up to two waste receivers.

9. The system of claim 1, wherein the handle is formed with a clip.

10. A biodegradable lawn waste collection system comprising:

(a) a waste receiver comprising an extruded tubular mesh structure formed from a biodegradable polymer composition, wherein the extruded tubular mesh structure has an initial configuration having an initial diameter (D_I), an initial width (W_I), and an initial volume, the waste receiver including a filling end and a sealing end, wherein the waste receiver is formed with a color selected from the group consisting of;

red, orange, yellow, green, blue, violet, black, and combinations thereof, wherein the color has an L* value that is less than or equal to 60; and

(b) a shaping insert configured for removable reception within the waste receiver, wherein the shaping insert has a shaping insert perimeter, a shaping insert proximal end, a shaping insert distal end, and a continuous sidewall extending between the shaping insert proximal end and the shaping insert distal end such that the shaping insert has a tubular configuration;
