Description
- The present invention relates generally to containers with lids, and more specifically to concrete washout containers with leakproof sealing lids that allow waste concrete and liquid to be transported, stored, and used to evaporate water from the container, thereby leaving dried concrete residue, which can be more easily recycled or repurposed.
- Concrete is composed of aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), cement (commonly Portland cement) and can also include other cementitious materials such as fly ash and slag cement (with the cement and cementitious materials acting to hold the aggregate together, water, and can also include other chemical admixtures. Depending on the intended use, fiberglass, chemicals and other additives can be added. Concrete is commonly transported to a construction site in concrete mixture delivery vehicles, typically concrete transport trucks (in-transit mixers) having a large rotating mixing drum. During transportation, the concrete is in a wet, relatively flowable state. At the construction site, the wet concrete mixture is installed. One typical method to deliver the concrete from the drum is via one or more pour chutes.
- After substantially all of the concrete mixture is unloaded from the delivery transport truck, a considerable amount of wet concrete continues to adhere to the pour chutes. In the past, this remaining wet concrete mixture was merely hosed off onto the ground or worse, rinsed into storm drains. However, the rinse water used to clean the pour chutes is considered a potential groundwater contaminant and is quite damaging to storm drain systems. Consequently, environmental laws have been strengthened to prohibit the disbursal of such rinse waters and solids (hereinafter referred to as “rinse water mixture”) onto the ground, onto streets, or down storm drains. All such rinse water mixture must be recouped and recycled without being allowed to flow into streets, storm drains or gutters or allowed to percolate into the soil.
- One way that has been used to deal with concrete rinse mixtures at large construction sites has been to deposit such rinse water mixtures in prefabricated lined evaporation pits. However, the construction of a prefabricated evaporation pit at smaller commercial and residential construction sites is impractical and not cost effective. Moreover, there is still the problem of transporting the rinse water mixtures.
- There are various devices and systems for removal of concrete chute rinse water mixture from the delivery vehicle. Many systems require the use of expensive and bulky hydraulic, pneumatic or electrical components which must be carried on the delivery vehicle. Such hydraulic or electrical components are expensive to purchase and maintain and awkward to carry on the delivery vehicle. Also, such hydraulic, pneumatic or electrical components leave the driver of the delivery vehicle vulnerable to hydraulic, pneumatic and electrical system failures which would prevent use of the equipment at the construction site. Still further, proposed equipment in the prior art can suffer from leakage of contaminated water during the normal operation. Many prior devices and methods require the use of the vehicle's mixing drum to store the recovered rinse water mixture. Storing such rinse water mixture in the mixing drum can adversely affect the integrity of the next load of concrete mixture prepared and transported within the mixing drum, unless the rinse water mixture is thoroughly drained from the mixing drum prior to the preparation of the next batch of concrete mixture. From a practical standpoint, this is a major disadvantage of such proposed equipment because there is a strong temptation among individual concrete mixture preparation personnel to reuse the rinse water mixture (already in the mixing drum) rather than to take the time to thoroughly drain and reconstitute the rinse water mixture and to replace it in the mixing drum with fresh water.
- There are also a variety of open flat bins that are used to collect the rinse water mixture. Such flat bins are positioned at a work site, and the rinse water mixture is deposited therein. In some cases, the water of the rinse water mixture is allowed to evaporate with the passage of time, and then the solids are transported back to the concrete mixing facility. For high volume worksites, often times, these bins—filled with rinse water mixture—are transported back to the concrete mixing facility, but with great difficulty, e.g., tarps are used to cover the open mouth thereof, and spillage is common. Moreover, once filled with rinse water mixture, these prior art bins are not stackable, which can potentially take up more room at a work site.
- There accordingly remains a need for improved concrete washout containers with leakproof sealing lid and with a way to permit evaporation of the water from the rinse water mixture while in the container.
- One embodiment of the invention provides a concrete washout container with leakproof sealing lid, comprising:
-
- a lid portion have a base and lip structures extending around the base, each lip structure having a first contour, which first contour extends from an upper end of a generally vertical lid portion wall, which generally vertical lid portion wall extends from the base, wherein the lip structures are flexible along the generally vertical lid portion wall; and
- a bin portion, the bin portion having an open mouth, the mouth defined by a rim structure located around a perimeter of the open mouth, the rim structure having a second contour which second contour extends above a top end of a generally vertical bin portion wall section, which generally vertical bin portion wall section connects at a bottom end to a generally horizontal bin portion wall section, and which generally horizontal bin portion wall section connects to sides walls of the bin portion, which side walls extend upwardly from a bottom of the bin portion;
- wherein the first contour, the generally vertical lid portion wall, and an outer perimeter of the base of the lid portion are complementary to and detachably and sealably contact and engage with the second contour, the generally vertical bin portion wall section, and the generally horizontal bin portion wall section of the bin portion.
- Another embodiment of the invention provides a concrete washout container with leakproof sealing lid, comprising:
-
- a lid portion have a base and lip structures extending around a perimeter of the base, the lip structures having a first C-shaped contour, the lid portion including an opening and opening cover to allow access the bin portion through the lid portion; and
- a bin portion, the bin portion having an open mouth, the mouth defined by a rim structure located around a perimeter of the open mouth, the rim structure having a second C-shaped contour, the bin portion having side walls extend upwardly from a bottom of the bin portion, the bin portion including forklift channels formed in a bottom thereof;
- wherein the lip structures of the lid portion detachably interference fit within the rim structure of the bin portion to provide for sealing between the lid portion and bin portion.

FIGS. 1 toFIGS. 6A-D , there are shown various views of an exemplary embodiment of a concrete washout container withleakproof sealing lid 10.FIG. 1 is an isometric top front exploded view showing itsbin portion 12 andlid portion 14.FIG. 2 is an assembled top front isometric view of the exemplary embodiment of the concrete washout container with leakproof sealing lid ofFIG. 1 .FIG. 3 andFIG. 4 are a front view and side view, respectively, of the exemplary embodiment of the concrete washout container with leakproof sealinglid 10 ofFIG. 2 .FIG. 5 is a top view thereof.FIGS. 6A-D show how thelid portion 14 engages with thebin portion 14. Thelid portion 14 has abase 16 andlip structures 18 extending around thebase 16. An opening 20 is preferably located on thelid portion 14, and acap 22 is used to detachably cover the opening. The opening 20 can be a male or female threaded opening and is adapted to engage an opposite threadedcap 22. Other types of know sealing devices can also be used. The opening 20 can be used to pump liquid out of the base portion and/or as opening to allow water to evaporate from thebin portion 14. One or moreoptional ports 24 can be included on thelid portion 14. Theports 24 can be provided either closed or open. And when opened (e.g., by bore through), this will allow water to evaporate through thelid portion 14, as will be discussed further below. Thelid portion 14 can be structurally reinforced byribs 26 formed on a top surface thereof. As best shown inFIGS. 1 , 2, and 5, thelip structures 18 can comprises separate sections, such as two on each of the four sides of thelip portion 14, withseparations separations individual lip structures 18 to flex and bend as necessary to conform to thebin portion 12. While twolip structures 18 are shown on each side of thelid portion 14, a different number of lip structures can be used. Turning to thebin portion 12, it has an upperopen mouth 30. Around themouth 30 is aperimeter 32 that has arim structure 34, which rimstructure 34 is adapted to engage with thelip structures 18 extending around thebase 16 of thelid portion 14, as will be discussed below. Therim structure 34 is shown as havinginterruptions 86. The interruptions are preferably aligned with theseparations 80 in thelid portion 14, such that when thelid portion 14 is engaged with thebin portion 12, channels are formed which provide anatural passageway 90 through which straps can be used to retain the concrete washout container withleakproof sealing lid 10 on a truck during transportation. Thebin portion 12 hasfront walls 36 andside walls 38. Pairs offorklift channels bin portion 12 and allow the concrete washout container withleakproof sealing lid 10 to be picked up from any side of thedevice 10. Thebin portion 12 will rest on base blocks 44. Thefront walls 36 andside walls 38 preferably flair out from a smaller bottom 41 to alarger mouth 30. This allows thebins portions 12 to be nested for storage and transportation, plus helps any material in the bin, such as cured concrete, etc. to be more easily ejected from thebin portion 12. Awaist portion 50 is preferably formed aroundwalls bin portion 12. Thewaist 50 may comprise indented channel. -
FIG. 6A is a detailed front cross-sectional view showing theexemplary lid portion 14 just before being engaged with thebin portion 12. As shown, thelip structure 18 extending around thebase 16 has a generally C-shapedupper end 94 that extends above a slightly slanted outvertical wall portion 96, that extends thebase 16. Ahorizontal section 98 extends from the generally C-shapedupper end 94 and when thelip structure 18 is completely engaged with therim structure 34 of thebin portion 12, provides an edge which can be used to pry tolid portion 14 off of thebin portion 12. Anouter surface 100 of the generally C-shapedupper end 94 will be sized and shaped so that it will closely confirm to aninner surface 102 of therim structure 34 of the of thebin portion 12 formed at theperimeter 32 thereof, near theopen mouth 30. Therim structure 34 will itself have a generally C-shapedportion 104. The generally C-shapedportion 104 extends upwardly from a generallyvertical wall section 106, which in turn extends from ahorizontal stub wall 108. Thehorizontal stub wall 108 extends outwardly from thewalls bin portion 12.FIG. 6B is a front cross-sectional view showing theexemplary lid portion 14 with onelip structures 18 of thelid portion 14 being engaged with therim 34 of thebin portion 12. As is shown, the C-shapedupper end 94 will start to conform about the around the generally C-shapedportion 104 that extends upwardly from the generallyvertical wall section 106 and horizontalstub wall section 108, and the slightly slanted outvertical wall portion 96 extending from the base 16 will likewise start to flex and snap into aspace 110 below the generally C-shapedportion 104 andhorizontal stub wall 108. Because of thevertical wall portion 96 is slightly slanted out and has some resilience, this will tend to push the C-shapedupper end 94 against the generally C-shapedportion 104 of therim structure 34 of thebin portion 12. Sections of thebase 16 of thelid portion 14 near thelip structure 18 will start to make sealing contact with the upper surface of thehorizontal stub wall 18.FIG. 6C is a detailed front cross-sectional view showing theexemplary lid portion 14 with bothlip structures 18 of the lid engaged with therim 34 of thebin portion 12, but not completely snapped into engagement. Finally,FIG. 6D is a front cross-sectional view showing theexemplary lid portion 14 with bothlip structures 18 of the lid completely engaged with therim 34 of thebin portion 12 to provide water tight sealing, even in areas of thepassageways 90, since even in these passageways, there is contact between the slightly slanted outvertical wall portions 96 that extend the base 16 with the generallyvertical wall section 106 that in turn extends from ahorizontal stub wall 108, and contact between the base 16 of thelid portion 14 and the top of thehorizontal stub wall 108 of thebase portion 12. -
FIG. 7 is a diagrammatic side view showing the exemplary embodiment of the concrete washout container withleakproof sealing lid 10 the invention with astrap 120 positioned around its middle section in thewaist 50 and being tilted by aforklift 130. In this way, the forklift or tractor can be used to tip over thebin portion 12 and dump out the contents therein, e.g., cured concrete debris. -
FIGS. 8-10 are various views of another embodiment of the exemplary embodiment of a concrete washout container withleakproof sealing lid 200.FIG. 8 is a top front isometric assembled view showing itsbin portion 212 andlid portion 214.FIG. 9 is a top front isometric view of theexemplary lid portion 214 thereof, andFIG. 10 is a top front isometric view of theexemplary bin portion 212 thereof. Except for the device being shorter and side walls which are about as twice as long as they are wide, thedevice 200 is almost the same as the embodiment shown inFIGS. 1-7 . However, since the structure is long and shallow, it can be tipped over to dispose of the material contained therein without a need for a tipping strap. Rather, users can pick up one side of the structure (e.g., by using a forklift or tractor) and effectuate the desired tipping. As with the embodiment ofFIGS. 1-7 , thelid portion 214 has arim structure 216 and anatural passageway 218 can preferably be formed where thelid portion 214 sits on thebin portion 212. Acap 220 is shown closing an opening (not shown) that passes through the top 226. Strengtheningribs 224 are preferably formed on thelid portion 214, andoptional ports 222 can be formed on thelid portion 214, with theoptional ports 222 either being provided as bored (or drilled out), or unbored. When openings are formed in the ports, this will aid in evaporation of liquid from theclosed bin portion 212. Thecap 220 can be removed so that users can access the inside of thebin portion 212 even without removing thelid portion 214, such as to pump water therefrom. As best shown inFIG. 9 ,separations 240 are preferably formed betweenindividual lip structures 216 of thelid portion 214, which separations 240 permit thelip structures 216 to more freely flex as may be required to conform to thebin portion 212. Thebin portion 212 preferably includes pairs offorklift channels bin portion 212 and allow thebase portion 212 to be picked up from any side of thedevice 200. Theforklift channels base portion 212. Around themouth 254 of thebase portion 212 is aperimeter 258 that has arim structure 260, which rim structure 32604 is adapted to engage with thelip structures 216 extending around thebase 226 of thelid portion 214. The functionality and manner in which thebase portion 212 andlid portion 214 engage together is the same as with the embodiment of the invention shown and described with respect to the concrete washout container withleakproof sealing lid 10 ofFIGS. 1-7 . - The
bin portions 12/212 andlid portions 14/214 are preferably formed of high strength plastic, such as cross-linked polyethylene, commonly abbreviated PEX or XLPE, and can be formed by techniques including but not limited to roto molding. Use of high strength plastic has many advantages, including that the device can be formed without sharp corners which would tend to collect cured concrete. Moreover, the appropriate plastic provides some flexibility and give, and by banging or otherwise shocking the walls of thebin portion 12, this will help release and cured concrete that otherwise might stick to the bin. - Although the
lip structures bin portions - The preferred embodiments of this invention have been disclosed, however, so that one of ordinary skill in the art would recognize that certain modifications would come within the scope of this invention. It is, therefore, to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described.
