DETAILED DESCRIPTION OF THE INVENTION

With reference to Figure 1, a containment system 100 according to the invention comprises a base unit 102 and at least one perforated grid 104, which is supported by the base unit 102. The base unit 102 and the grid 104 They can be formed of polyethylene, which provides excellent chemical resistance and mechanical properties. Alternatively, base unit 102 and / or grid 104 may be made of any combination of materials that provides sufficient chemical resistance and mechanical properties. Base unit 102 and grid 104 may be formed of the same or different materials. Base unit 102 is preferably manufactured by rotational molding.

In a preferred embodiment the base unit 102 and the grid 104, viewed from the top, generally have a rectangular shape. Base unit 102 is preferably in the form of a tray with an open top. It is observed that the term base unit and basin is used in a

52-1142-15

MEXICAN INSTITUTE OF PROPERTY

INDUSTRIAL interchangeable through this specification and is intended to be equivalent terms. It will be appreciated that other shapes are possible and contemplated for base unit 102 and grid 104 (eg, square, hex, etc.). It will also be appreciated that base unit 102 and grid 104 can have a wall thickness that is greater or less than the illustrated embodiments without departing from the scope of the invention.

Grille 104 includes an upper side 105 adapted to contact containers or drums that are placed in grid 104. Grid 104 also includes a lower side that is opposite to upper side 105. Additionally, grid 104 includes a peripheral edge 107 extending around a perimeter of grid 104. A plurality of perforations 108 are provided through screen 104, which extend between top side 105 and bottom side to allow fluid to pass through screen 104. Although holes 108 are shown to be circular, it will be understood that the perforations 108 can be in any number of shapes that allow fluid to pass through the grid 104 into the base unit 102 (for example, the perforations

52-1142-15

they can be configured in slits or grooves).

When containment system 100 is used with a single 55 gallon drum, the top side 105 of grid 104 may have a sufficient area to support a standard 55 gallon drum (and a generally square shape can be defined). And when containment system 100 is used with two 55-gallon drums, the top side 105 of grid 104 preferably has a sufficient area to support two standard 55-gallon drums in parallel on base unit 102 (as illustrated). It will be appreciated that the size scale of the containment system 100 can be modified to allow any number of configurations to allow sufficient drum storage.

As shown in Figures 1-2, base unit 102 includes a bottom portion 110 and a first and second side primary wall 112, 114. The first and second side primary walls 112, 114 extend upward from the bottom 110 toward an edge 111, shown in greater detail in Figure 3. For reference, the first and second side primary walls 112, 114 may also be referred to as a first pair of side walls. Base unit 102 also includes a

the two pairs of opposite side walls 112, 114,

116, 118 to form a bucket to collect and contain fluids that can pass through perforations 108 in grid 104. The 102 base unit, when resized for use with a single 55-gallon drum, may have a capacity to hold 66 gallons or more of liquid (thereby complying with the provisions of the Uniform Fire Code paragraphs 79.405 and 79.406), which is greater than 110% of the volume capacity of a typical 55-gallon drum. Alternatively, when adjusting the base unit 102 for use with two 55-gallon drums, the base unit 102 can have a minimum capacity of 122 gallons.

The bottom part 110 and the grid 104 are vertically separated from each other when they are in an assembled state. This

52-1142-15

MEXICAN INSTITUTE

DS THE PWMEDAD

INDUSTRIAL SEPARATION provides the aforementioned ability to contain fluids passing through screen 104. Bottom part 110 includes base parts 122 with top base surfaces

124 oriented toward grid 104. In addition, bottom portion 110 includes two parallel raised sections

125 cooperating to define a pair of channels 126 that are separated by foundation portions 122. Each raised section 125 includes a top channel 128 surface facing grid 104. As shown, base portion 122 extends on both sides of channels 126. The upper channel surfaces 128 are arranged so that they are vertically offset from the grid 104 by a distance that is less than a vertical distance between the upper base surface 124 and the grid 104. Simply stated, the upper channel surfaces 128 are closer to grid 104 than upper base surface 124 of base portion 122 to grid 104. Because of this, a plurality of base units can be stacked one inside the other or nested, as will be described later.

receive the fork of a forklift or lift oar? Therefore, the lower part 110 of the base unit 102 can be configured such that the forklift or tug can be used to lift the containment system 100. This allows for improved transportability and easier use of the delivery system. containment 100 or a plurality of base units 102, alone or when in nested arrangement.

Preferably, at least one support pillar 132 is provided with an upper part 133 at the bottom 110. As illustrated, three support pillars 132 are provided at the bottom 110. However, it will be appreciated that more or less can be used support pillars 132 without departing from the scope of the invention. As shown, the support pillars 132 extend upward from the base portion 122 of the bottom portion 110 such that it joins the distance between the grid 104 and the bottom portion 110. Specifically, the upper portion 133 of the support pillar Support 132 contacts the underside of grid 104. Support pillar 132 provides additional tension to containment system 100 by supporting grid 104. Support pillar 132 is preferably formed

Additionally, fundamentally with the bottom part 110, but may be a separate component. Additionally, the support pillar 132 may be of a grooved hollow type construction. This type of construction helps reduce the total weight of the containment system 100 and allows multiple base units 102 to nest as will be described later. Preferably, a plurality of support columns 134 having an upper surface 135 are also formed on the side walls 112, 114, 116, 118.

The first and second primary side walls 112, 114 and the first and second connecting side walls 116, 118 extend upward from the bottom 110 just outwardly to reduce the footprint of the base unit 102, while allowing sufficient fluid storage capacity. In particular, a distance between the first and second side primary walls 112, 114 near the bottom 110 is preferably less than the distance between the first and second primary walls 114 near the grid 104. a distance between the first and second connecting side wall 116, 118 close to bottom 110 is preferably less than the distance between the first and second side walls

INDUSTRIAL connecting 116, 118 near grid 104. This form of outward extension of the first and second lateral primary wall 112, 114 and the first and second connecting lateral walls 116, 118 also allows for improved nesting of multiple units of base. The first and second primary side walls 112, 114 and the first and second connecting side walls 116, 118 of the base unit 102 are also preferably grooved. Like the flutes of the support post 132, the tension of the base unit 102 is increased and the nesting of multiple base units is improved. In particular, when multiple base units have grooves, the possibility of wedging or bringing the base units together is reduced.

Referring to Figures 2-3, containment system 100 may also include at least one nesting limiter 134 extending inward and upward and more preferably two nesting limiters 134, each disposed on one side of the unit. base 102. Nesting limiter 134 includes support surface 136 facing grid 104. As illustrated, nesting limiter 134 can have a rectangular shape in a flat, elevated view and contacts bottom 110.

52-1142-15

Alternatively, nesting limiter 134 may be vertically spaced from bottom 110. Support surface 136 is vertically spaced from grid 104 at a distance that is less than a vertical distance between the top base surface 124 and the grid 104 and greater than a vertical distance between the upper surface of channel 128 and grid 104. Additionally, support surface 136 is spaced from grid 104 by a distance that is less than a vertical distance between bottom 110 and grid 104 and greater than a vertical distance between top 133 of support pillar 132 and the grid 104. This type of arrangement further helps minimize footwear for nested base units.

In addition, a nesting limiter 134 may be provided on the first connecting side wall 116 to a location adjacent to the first primary side wall 112. Nesting limiter 134 allows an additional connection between the first connecting side wall 116 and the first wall Primary primary 112 to improve tension and rigidity of base unit 102. As illustrated, nesting limiter 134 is integral with first connecting side wall 116. However, it will be understood that the

52-1142-15

nesting limiter 134 may be a separate component and merely installed on the first connecting side wall 116.

The arrangement of nesting limiter 134 and, particularly, support surface 136 provides numerous advantages. For example, when base units 102 are nested within one another, nesting limiter 134 prevents multiple base units from fitting together. Specifically, the support surface 136 of a first base unit is contacted with a bottom surface 110 that is opposite to the base surface of a second base unit to prevent over-insertion of the second base unit in the first base unit. This separation provides easy removal of the second base unit from the first base unit. Additionally, nesting limiter 134 provides added rigidity by contacting the first connecting side wall 116 and the first lateral primary wall 112 and, optionally, contacting the first connecting side wall 116 and the second lateral primary wall, further improving thus the stiffness of base unit 102.

As noted above, and with

52-1142-15

With particular reference to Figure 3, the containment system 100 also includes edge 111. Edge 111 is generally L-shaped in a vertical cross-sectional plane and includes an inwardly extending section 138 extending inwardly from the side walls 112, 114, 116, 118 and an outwardly extending section 148 terminating within a cutting edge 150. Cutting edge 150 is present by the way base unit 102 is manufactured. Specifically, a hollow solidified polymeric structure is manufactured by rotational molding, and then the hollow polymeric structure is cut into two base units along the cut edge area 150 (some of the material can be removed can be removed between the two base units formed in this way, leaving a cutting edge on each base unit). For reference, this process will be discussed in more detail later in the explanation of the method of manufacturing a pair of base units.

As shown, inwardly extending section 138 is vertically spaced from bottom 110 and supports grid 104. Inwardly extending section 138 can optionally cooperate with supporting columns 134

52-1142-15

IMPI inMKTMXL to support grid 104 and any objects placed on grid 104. Inwardly extending section 138 and upper surface 135 of support columns are facing in the same direction, which is toward grid 104 , to provide a sufficient support surface to mesh with grid 104.

As shown in Figures 1 and 3, the upwardly extending section 148 extends upward in a direction away from the bottom portion 110. In a preferred embodiment, the upwardly extending section 148 may extend upward about 4, allowing twenty-four base units to nest at a height of less than ten feet. Therefore, the upwardly extending section 148 helps to reduce the lateral and longitudinal movement of the grid 104, thereby ensuring the total stability of the containment system 100. The upwardly extending section 148 and the section which Inwardly extending 138 cooperate to define edge 111 of containment system 100 at the open top. Therefore, grid 104 is disposed within the peripheral opening defined by the L-shaped edge 111 of the base unit.

In the illustrated embodiment, edge 111 defines a quadrilateral having adjacent sides that are arranged 90 ° with respect to each other. Furthermore, the upwardly extending section 148 on each side of the quadrilateral is not flat. Additionally, the upwardly extending section 148 includes at least one recessed area 152 and at least one non-recessed area 154. Embedded area 152 of one base unit is configured to interact with non-embedded area 154 of another base unit as will be described later. Embedded area 152 is disposed inwardly laterally from non-embedded area 154.

As shown in Figure 2, the inwardly extending section 138 may include a plurality of supports 156. The upwardly extending supports 156 are brought into contact 104. Specifically, the lower side 106 of the grid 104 that is close to the peripheral edge 107 is brought into contact with the inwardly extending section 138 of the edge 111 between the plurality of upwardly projecting supports 156 and the extending section upwardly 148 from edge 111. Thus, side walls 112, 114, 116, 118 are connected to each other or joined together with grid 104 to

52-1142-15

avoid excessive outward deflection of the side walls.

Referring to Figure 4, a containment storage area 170 comprising two base units 102 of the containment system shown in Figure 1 in a parallel arrangement. It will be appreciated that in use, a rack 104 is placed in each of the two base units 102 to establish a common horizontal surface to support the containers. Embedded areas 152 and non-embedded areas 154 of the respective edges

111 Two base units are formed cooperatively and connected to each other. This improves the tension of the containment storage area 170 and also reduces the possibility of fluid escaping between the base units. It will be appreciated that recessed areas 152 and non-recessed areas 154 are also end-to-end and end-to-side aligned, allowing for the coupling of more than two base units 102 in various configurations.

The multiple base units 102 can be nested together to reduce the amount of space required during storage and transport. In order to facilitate the illustration, the Figures

5-8 shows multiple views of two 102 base units

52-1142-15

IMPI

in a nested configuration. It will be appreciated that substantially larger amounts (eg,> 10) of base units can be nested together for storage or transport, as desired.

As best shown in Figure 6, each base unit 102 has a total height HO measured from the side of bottom part 110 opposite top base surface 124 (i.e., the part of base unit 102 that would contact the ground) with respect to the cutting edge 150. Preferably, the outer side of edge 111 has a height HR that is within the range of from about 10% to about 20%, more preferably from about 12.5% to about 17.5%, and more preferably about 15% of total HO height. As shown in Figures 7-8, the base units are 180 ° out of phase with each other, which means that the nesting limiters 134 at one end of a lower base unit contact the part lower 110 of the next successive base unit nested in it. This stack

180 ° out of phase continues with each successively nested base unit to prevent base units from wedging together (making it difficult to remove).

The novel design of the base units of

52-1142-15

IMPI

Containment systems in accordance with the invention allow a large quantity to be stored and transported in a compact area, which constitutes a substantial improvement over current products. For example, only two drum containment systems 152 currently sold by the assignee of the present application with product numbers 5253-YE and 5260-YE may be transported in a 40 'high cubic container. However, approximately two two drum containment systems 440 according to the present invention can be transported or stored in the same 40 'high cubic container. Obviously, similar improvements in packing density are obtained for 53 'high cubic containers (194 vs. 616). The improvement in packing density achieved by the invention reduces the amount of energy required to transport a containment system.

Referring to Figure 9, a method of placing a container in a storage area is illustrated. In Step 1000, a plurality of containment systems are provided. Each containment system includes a rotationally molded polymer base unit in the form of a bucket having an open top. The base unit

52-1142-15

IMPI includes a generally L-shaped open top edge composed of an upwardly extending section ending in a cutting edge and an inwardly extending section. The edge of the base unit defines a quadrilateral that has adjacent sides that are arranged 90 ° from each other. The section that extends up from the edge on each side of the ring is not flat and includes at least one recessed area. Each containment system also includes at least one perforated grille that has an upper side, a lower side, and a peripheral edge. The at least one perforated grid is supported, at least in part, by the section extending inward from the edge such that a container can be supported on the upper side of the grid on the tray. In Step 1002, the plurality of containment systems is arranged in parallel such that the embedded area of one of the plurality of containment systems receives an unbuilt area of another of the plurality of containment systems and systems Containment lines are connected in this way. Additionally, the plurality of containment systems can be arranged such that the grids of the plurality of containment systems cooperate to

52-1142-15

IMPI

define a common horizontal plane. ---------- Therefore, a plurality of base units can be nested together during transportation and storage, allowing for substantial space savings and reducing energy costs during transportation. Specifically, more base units can be transported in the same space, reducing the number of transfers needed to transport an equivalent number of containment systems. This is possible because each successive base unit in the nested base unit stack is rotated 180 ° (end-to-end) with respect to the base unit within which they are nested, making it almost impossible to fit the units with each other when under load. This also makes it easier to remove each unit from the stack.

Alternatively, a plurality of base units can be provided to an end user in a first configuration where the plurality of base units are in a stack and nested together. The end user separates one or more individual base units from the stack and places one or more grids on the base units to form containment systems. If desired, two or more systems

52-1142-15

Containment systems may be placed with the bottom of the base unit on the ground or other generally horizontal surface such that two or more containment systems are brought together through the lateral parts that extend upward from the L-shaped edge of base units, which include sections that are arranged outward and adjacent sections that are arranged inward on each side of the base unit. Containment systems can thus be used to support drums or other containers that contain liquids or other materials.

Referring to Figure 10, a method of manufacturing a pair of base units for a containment system is shown. In step 2000, a rotational molding cavity containing a polymeric resin is simultaneously heated and rotated. Specifically, the cavity is heated to a temperature to which q which the polymeric resin forms a melted layer on an interior surface of the rotational molding cavity that defines the base unit pair. Each base unit is in the form of a bucket and includes a generally L-shaped edge. The edge includes an upwardly extending section and an inwardly extending section. In Stage 2002, the cavity

52-1142-15

IMPI

Rotational molding is cooled to solidify the polymeric resin. In Step 2004, a hollow solidified polymeric structure is removed from the cooled rotational molding cavity. In Stage 2006, the hollow solidified polymeric structure is cut such that the section extending up from the edge of each pair of base units ends at a cutting edge.

This method offers several advantages. For example, multiple base units can be manufactured at once. Therefore, the production result increases compared to a method in which only one base unit is manufactured at a time.

Additionally, only one set of production equipment is required instead of two sets of production equipment to achieve equivalent performance. Still further, the amount of polymer waste is reduced, as two base units share the cutting edge.

Technicians in the art will easily think of the advantages and additional modifications. Therefore, the invention in its broadest aspects is not limited to the specific details and illustrative examples shown and described herein. Accordingly, various modifications can be made
