Flexible container 106 is flexible to permit the agitation of materials placed therein from the exterior of flexible container 106 as discussed in more detail herein. Further, flexible container 106 is flexible to permit the collapsing of flexible container 106 for easy storage as discussed in more detail herein.
Flexible container 106 is illustratively shown as a bag 110. Bag 110 is formed from a generally cylindrical wall 112 of flexible material, such as a plastic bag. In one example, bag 110 is made from polyethylene plastic. Alternatively, bag 110 may be made from any clear flexible plastic polymer.
A bottom portion 114 of cylindrical wall 112 is sealed together so that an interior 116 of bag 110 is able to hold materials placed therein. The seal is represented by a dashed line in
Once bottom portion 114 is sealed, interior 116 of bag 110 has a single compartment for holding materials therein. As explained herein, the dry mix masonry component 102 and the liquid component 104 are received through opening 108 into the single compartment of interior 116 and the resultant masonry composition is removed from the single compartment of interior 116 through opening 108.
The size and thickness of bag 110 may be tailored to the type and quantity of masonry compositions being produced from dry mix component 102 and liquid component 104. Exemplary masonry dry components 102 include dry cement mix, dry mortar mix, and dry tile grout mix. At least some of the exemplary masonry components are available in prepackaged bags of various sizes. For example, dry cement mix is typically available in one or more of the following sizes of prepackaged bags: 10 pounds, 20 pounds, 40 pounds, 50 pounds, 60 pounds, and 80 pounds. In one embodiment, bag 110 is sized for mixing batches of cement composition (40 to 80 pound dry mix bags) and is about 22 inches wide and about 34 inches tall. As such, bag 110 may be used to mix a full 80 pound bag of dry cement mix at one time. In another embodiment, bag 110 is sized for mixing tile composition or small batches of cement composition (10 to 20 pound dry mix bags) and is about 18 inches wide and about 24 inches tall.
In the preferred embodiment, the thickness of bag 110 is chosen such that bag 110 permits easy storage (when not in use) and proper mixing of dry mix component 102 and liquid component 104. In one embodiment, bag 110 is at least about 0.004 inches thick. In another embodiment, bag 110 is at least about 0.006 inches thick. In a further embodiment, bag 110 is about 0.007 inches thick. In still a further embodiment, bag 110 is between about 0.004 inches thick to about 0.007 inches thick.
In one embodiment, bag 110 is made of a clear or semi-transparent flexible material to permit a user to observe the mixing of the materials from the exterior of bag 110. This permits the user to see the mixing process and to verify that a complete and thorough mix of the dry mix masonry component and the liquid component is produced for every batch. In an alternative embodiment, bag 110 is made of a colored or opaque material.
Cylindrical wall 112 of bag 110 includes at least one portion 118 whereupon indicia are printed or otherwise located. Exemplary indicia includes trademark information, contact information, directions for use of apparatus 100 such as exemplary methods 200 or 300, and warnings, such as suffocation warnings.
In one embodiment, the surface of interior 116 of bag 110 is coated with a slickening agent. Slickening agents are known in the art. In one embodiment, a 250 ppm oleamide slickening agent is used. The slickening agent eases the opening of bag 110 by reducing static and permits materials within bag 110 to move easier relative to an interior surface 119 of bag 110. This aids in the mixing of the masonry composition and in the removal of the masonry composition from bag 110.
In the preferred embodiment, binding member 109 is illustratively shown as a hook and loop type tie 120. Tie 120 includes a strap 122 and a buckle 125. Strap 122 includes on one side a first region 123 having hook features and a second region 124 having loop features. Buckle 125 includes an aperture 126 sized to receive strap 122. In use, tie 120 is positioned around a gathered portion of flexible container 106 and strap 122 is inserted through aperture 126 of buckle 125. The inserted portion of strap 122 is then doubled back so that it overlaps the remaining portion of strap 122 and pulled tight against buckle 125. Once tightened the hook features of the inserted portion of strap 122 interact with the loop features of the remaining portion to secure tie 120. Other exemplary binding members 109 include a plastic closure strap, twist ties, garbage bag ties, bands, rope, or other suitable binding members that may at least substantially close opening 108.
Flexible container 106 may be used as a disposable product that does not require any cleanup. Once all or a desired portion of the resultant masonry composition is removed from interior 116, flexible container 106 may be discarded. Alternatively, flexible container 106 may be reused to mix several batches of masonry composition either successively or at spaced apart intervals of time, such as days, with proper cleaning. Surface 119 of interior 116 should be generally smooth to aid in expelling of the resultant masonry composition and in the cleaning of interior 116, if desired. In one example, interior 116 may be cleaned by spraying interior 116 with water or another liquid. It should be understood that interior 116 of flexible container 106 does not require cleaning between each batch of masonry composition as long as the subsequent batch is made within a reasonable amount of time so that any residue from the previous batch has not set or hardened.
A first exemplary method 200 of mixing dry mix component 102 and liquid component 104 is shown in
As represented by block 204, opening 108 of flexible container 106 is substantially closed to retain dry mix component 102 and liquid component 104 within flexible container 106. Opening 108 may be substantially closed by gathering a top portion 115 of flexible container 106 together and holding it with a binding member, gathering top portion 115 of flexible container 106 together and twisting the gathered portion, or by gathering top portion 115 of flexible container 106 together, twisting the gathered portion, and securing it with a binding member.
As represented by block 206, the dry mix component and the liquid component are thoroughly mixed to produce the masonry composition. It should be understood that dry mix component 102 and liquid component 104 are at least partially mixed when they both are positioned within interior 116. In one embodiment, the thorough mixing of dry mix component 102 and liquid component 104 is accomplished by agitating components 102, 104 from the exterior of flexible container 106. Exemplary methods of agitation include kneading the components 102, 104 from the exterior of flexible container 106, rolling flexible container 106 including components 102, 104 in interior 116 on the ground or other surface, rolling flexible container 106 including components 102, 104 in interior 116 on the ground in a back and forth fashion “rock and roll movement,” and/or shaking flexible container 106 including components 102, 104 up and down. In the case of an 80 pound bag of dry mix cement agitated by the “rock and roll movement,” the resultant thoroughly mixed cement component may be produced in less than one minute of agitation time. In one example, the agitation time should be about 30 seconds.
It should be noted that by mixing dry mix component 102 and liquid component 104 inside a substantially closed container, none of individual components 102 and 104 or slurry formed from components 102, 104 is spilled or splashed onto unintended areas. As such, the substantially closed flexible container 106 minimizes mess during mixing and protects the integrity of the surrounding region.
Once components 102, 104 are thoroughly mixed, opening 108 of flexible container 106 is opened to permit the removal of the resultant masonry composition from interior 116 of flexible container 106, as represented by block 208. In one embodiment, top portion 115 of flexible container 106 is positioned proximate to the location that the masonry composition is to be applied prior to the opening of opening 108. As such, the resultant masonry composition may be slid out of flexible container 106 without ever having to physically lift the whole resultant masonry composition as typically done with a bucket or wheelbarrow mixing arrangement and without spilling the resultant masonry composition onto the surrounding area. In one example, the masonry composition is slid out of flexible container 106 by lifting up on bottom portion 114 of flexible container 106 to move the resultant masonry composition to top portion 115 and eventually out of flexible container 106.

Similar to flexible container 106, flexible container 850 is formed from a generally cylindrical wall of flexible material, such as a plastic bag. A bottom portion 861 of cylindrical wall is sealed together so that an interior of flexible container 850 is able to hold materials placed therein. The seal 860 is represented by a dashed line in
One or both of handles 802 and 804 of flexible container 800 and one or both of handles 852 and 854 of flexible container 850 may also be used to assist in the mixing process. By gripping the respective handle it is easier for the user to rock the respective flexible container to mix the dry mix component 102 and the liquid component 104.
If not all of the resultant masonry composition is required for the particular application, such as setting a post, the remaining portion of the resultant masonry composition may be left in flexible container 106 and discarded along with flexible container 106. Alternatively, the remaining portion of the resultant masonry composition may be cleaned out of flexible container 106 before it hardens allowing flexible container 106 to be reused at a later date. As stated above, flexible container 106 may be reused to make several batches of masonry composition without cleaning flexible container 106 as long as the batches of masonry composition are made within close temporal proximity of each other. In the case of cement compositions, flexible container 106 may be used to make six to seven successive batches of cement composition within about 45 to about 60 minutes without requiring cleaning of flexible container 106 between batches.
The above stated exemplary method does not require mixing tools, such as garden trowels, shovels, or hoes to produce the resultant masonry composition. Further, the above stated exemplary method does not require the use of a wheelbarrow, bucket, mortar box, mixing barrel, or other rigid container for mixing the dry mix component 102 and liquid component 104 therein.
