Sidewall 20 comprises, but is not limited to, a generally cylindrical shape that extends between a first annular peripheral end 21 and a second annular peripheral end 22 generally parallel with and spaced from the first annular peripheral end 21 along the central longitudinal axis 12. Sidewall 20 also comprises a circumscribing exterior surface 24.
Referring to FIG. 3, sidewall 20 further comprises a circumscribing interior frictional surface 26 that defines an open-ended axial or longitudinal bore or chamber 28 extending between respective first and second open peripheral ends 21, 22.
Sidewall Material
In one embodiment, the flexible circumscribing trim and sift bag sidewall 20 is formed of, but not limited to about a two-hundred denier (200) to about four-hundred-twenty (420) denier nylon or polyester fabric, or an equivalent functioning material thereof. This material provides the necessary interior cylindrical frictional surface 26 with a coefficient of friction that provides an efficient trimming surface for the apparatus 10 while reducing excessive dust during use.
The flexible material configuration of side wall 20 further allows apparatus 10 to be repeatedly opened and closed between the expanded configuration and the collapsed configuration along the central longitudinal axis 12 without causing substantial wear or other deleterious effects on apparatus 10.
Coil Spring and Hem Assembly 30
As illustrated in FIG. 1, the dry trim and sift bag apparatus 10 further comprises a coil spring and hem assembly 30 operatively coupled to sidewall 20 for providing means for forcing or urging the flexible circumscribing trim bag sidewall 20 from the collapsed configuration state into the expanded configuration state. The expanded configuration of the flexible circumscribing trim bag sidewall 20 is maintained by coil spring and hem assembly 30 until a subsequent compressive force is applied thereto. The coil spring and hem assembly 30 can be operatively coupled on the interior surface 26 or exterior surface 24 of sidewall 20 by, but not limited to, stitching.
Referring to FIGS. 1 through 4, an embodiment of the coil spring and hem assembly 30 comprises a coil spring 32 and a hem 40 covering or enveloping the coil spring 32. Generally parallel flanking stitching or stitch lines 48 and 50 (FIG. 3) secure the hem 40 to the sidewall 20 with the coil spring 32 interposed between hem 40 and sidewall 20. In one embodiment, the coil spring 32 is interposed between the hem 40 and the exterior surface 24 of sidewall 20. In another embodiment, coil spring 32 can be interposed between the hem 40 and the interior surface 26 of sidewall 20.
Coil Spring 32
Still referring to FIGS. 1 through 4, an embodiment of the coil spring 32 comprises a coil or spiral spring medial portion 34 (Ha 4) that extends along the exterior surface 24 of the sidewall 20 between a first spring end loop 36 disposed adjacent to and circumscribing the first peripheral end 21 of sidewall 20 and a second spring end loop 38 disposed adjacent to and circumscribing the second peripheral end 22.
Spring Hem 40
The spring hem 40 is generally complemental in shape to the coil spring 32 and comprises a medial hem portion 42 (FIG. 4) attached to and extending between a first hem loop end portion 44 and a second hem loop end portion 46. Medial spring hem portion 42 covers or envelopes the spiral spring medial portion 34 of coil spring 32 while the first and second hem loop end portions 44, 46 cover or envelope the first and second spring end loops 36, 38 respectively.

In Use and Operation
In use and operation, the collapsible multi chamber screen partitioned dry trim and sift bag apparatus 10 is utilized by an operator in a multiple motion series method that is both ergonomic and efficient.
Prior to the operator preforming one or more of the motion series methods, the product is initially cut down to desired size and dried to a state that when rubbed between the ones fingers results in the leaf and phyllary of the flowers/buds being flaked off. Once the product is dry, the second axial end cap or collection end cap is closed via second zipper 128. Then the product is loaded into the first end trim chamber 70 that is then closed via first zipper 98. As delineated above, the funnel or cone-like members 84 and 114 are secured to the sidewall 20 using the magnetic snap pairs 140, 142 and 144, 146.
In one embodiment, the operator is preferably in a standing position while performing any one of the motion series methods. The motion series methods generally comprises at least one of the following methods.
Shaking Method
One method comprises transversely shaking an upright vertically positioned apparatus 10, screen end down, generally side to side along transverse or lateral axis 14 utilizing hand pockets 150, 152. In particular, the shaking motion series starts out with the operator in a standing position and having hands in respective hand pockets 150, 152 with the apparatus 10 in a vertical position. Then, transversely shaking the apparatus 10 with loaded product in a side-to-side motion along transverse or lateral axis 14 wherein the side-to-side motion can include an orbit. In general, the shaking motion series is performed in a rhythmic motion forty to fifty times in a minute for about one minute. Motion is done with enough force to move the product in a circular motion, listening/feeling for it to rise and then rolling, tumbling down the inside of the trim chamber 70.
Another shaking method comprises positioning apparatus 10 in a horizontal position and then shaking apparatus 10 from waist to head or shoulder level and back to waist level by holding the first pair of U-shaped strap handles 104, 106 in one hand and the second pair of U-shaped strap handles 134, 136 in the other hand.
Twisting Method
A further method comprises twisting a horizontally positioned apparatus 10 in a clockwise and counter clockwise arc or rotation generally about an axis perpendicular to longitudinal axis 12 or, in other words generally perpendicular to the height of the operator. In one embodiment, the twisting motion series starts out with the operator in a standing position with the first pair of U-shaped strap handles 104, 106 held in one hand and the second pair of U-shaped strap handles 134, 136 held in the other hand with apparatus 10 horizontally disposed. More specifically, each set of U-shaped strap handle pairs 104, 106 and 134, 136 are respectively gripped together in each respective hand to make a handle that meets near the center of each end-cap but is not touching each respective end cap. U-shaped strap handles 104, 106 and 134, 136 are generally tension handles and allow the operator to make a cross-frictional twist motion in the horizontal position. With a controlling grip of the handles, the operator twist apparatus 10 in a clockwise and counter clockwise arc or rotation generally about an axis perpendicular to longitudinal axis 12. In particular, and in one embodiment, the operator horizontally positions apparatus 10 at chest level with elbows lifted out from sides and arms stationary. Then, the operator synchronously twist each wrist back and forth like turning a dial to produce a one-hundred-eighty degree spinning motion of apparatus 10 away from and back to the chest of the operator.
During the twisting motion, the operator preferably listens and/or feels a sweeping motion of the product along the horizontal lower half the interior of sidewall 20 of the trim chamber 70. One cycle of the twisting motion is preferably performed forty to fifty times in one minute.
Bouncing Method
Another further method comprises bouncing an upright vertically positioned, screen end down, apparatus 10 up and down generally along longitudinal axis 12 utilizing hand pockets 150, 152. In one embodiment, the bouncing motion series starts out with the operator in a standing position, the apparatus 10 vertically positioned, and the respective hands of the operator in respective hand pockets 150, 152. Then, bouncing the upright positioned apparatus 10 vertically up and down generally along longitudinal axis 12.
Example Combinations of Motion Series
In one embodiment, the operator is preferably in a standing position and uses a combination of the motion series to trim and shift the product.
For example, the operator can first perform the shaking motion series followed by the bouncing motion series. Then, if necessary, the twisting motion series followed by the bouncing motion series.
In another embodiment, the operator can perform the twisting motion series followed by the bouncing motion series. Then, if necessary, the operator can perform the shaking motion series followed by the bouncing motion series.
In a further embodiment, the operator can perform the shaking motion series then the twisting motion series followed by the bouncing motion series.
In another further embodiment, the operator starts out with the twisting motion series then the shaking motion series followed by the bouncing motion series.
Other orders of motion series including alternating motion series are employed as desired by the operator to obtain the above delineated trim and sift process of operation. As desirable by the operator, each respective motion series can be halted and the product checked for progress.
The multiple handle means make operating the collapsible multi chamber screen partitioned dry trim and sift bag apparatus 10 thru each motion series ergonomic and efficient.
Once the desired motion series is completed to obtain a satisfactory or desired trim, the second axial end cap 110 is preferably partially opened and the sifted product or waste product is funneled out of the collection or sift chamber 72. Then, the first axial end cap 80 is preferably partially opened and the trimmed product is funneled out of the trim chamber 70. Accordingly, apparatus 10 is unloaded and ready for subsequent use.
Trouble Shooting
Each operator/person will have to make slight adjustments to their body movements to obtain the internal motion of the product. Additionally, one of the following variables can be adjusted before repeating the desired motion series for best results.
Check product dryness, if the product is not breaking down it may not be dry enough or if product break down completely it may be overly dry. Correct dryness is important.
Check to see that apparatus 10 is not overloaded precluding product from moving freely. If overloaded, simply remove some of the product and continue with the desired motion series. Remember the product must have room to move around for friction trimming to occur.
Check to see that the product is cut down small enough.
Finally, if the product is not satisfactorily breaking down enough, twist and/or shake apparatus 10 faster or more aggressively.
Friction Trimming
In one aspect, the collapsible multi chamber screen partitioned dry trim and sift bag apparatus 10 provides friction trimming comes from multiple sources during the motion series of operation of the collapsible multi chamber screen partitioned dry trim and sift bag apparatus 10. For example, friction trimming is accomplished by the tumbling, rolling, and swirling of the product against itself and the interior surface of sidewall. When apparatus 10 goes through the twisting motion series with a quick reversal in direction, the product is sent in one direction while the apparatus 10 is moving in the opposite direction thereby creating a cross-frictional trim that quickly removes waste. The shaking and bouncing motions creates friction against the sides and screen. The waste being sifted off also aids in removing unwanted particles. Each of the motion series is designed for speed, efficiency and cleanliness.
