  • the cover 18 of the pool strainer bucket 10 is also flexible and it may be formed from materials such as polymer rubber or an elastomer such as TPU.
  • the aperture 20 is sized and shaped such that it forms a one way valve. Leaves and debris move into the interior cavity 15 when there is flow into the bucket 10 through the aperture 20, but do not move out. When the pump that causes flow of water from the pool into the bucket is stopped the one way valve 20 of the cover 18 acts to retain debris and leaves within the bucket rather than allowing them to float out. In the

  • a handle 23 to allow a user to remove the bucket 10 from the skimmer well with a pool tool in the form of an elongate member such as a hook, a stick, a broom handle, etc. This is particularly advantageous in winter as it allows the user to remove the pool strainer bucket 0 from the pool system without having to reach their hand into the cold water.
  • the cover 18 has a closure system 25 to allow press fit of the cover to engage the bucket 10 in a closed configuration.
  • the pool strainer bucket 10 comprises a substantially flexible and collapsible wall 1 1 extending upwardly from a base 12.
  • the wails 1 are perforated to allow water to flow through the bucket, drawing leaves and debris from the pool into the strainer bucket.
  • this embodiment may be stored and transported in its collapsed configuration as illustrated in Fig. 5. For example, posting this embodiment in its collapsed configuration will reduce its volume (as compared to its volume when expanded) and this will typically reduce the associated postage costs, which can help to reduce the costs of distributing the product to remote purchasers.
  • the cover 18 may comprise a separate piece from the strainer bucket 10.
  • the cover 18 is designed to fit about the rim 13 of the bucket 10 and enclose the interior cavity 15.
  • the cover includes an aperture 20 shaped as a cross extending through the cover into the interior cavity 15 of the bucket 10.
  • the cover 18 is integral with the bucket 10.
  • the strainer bucket allows water and debris and leaves to flow into the bucket under the force of a flow of water from the pool .
  • the water then leaves the bucket 0 through the perforated wails 1 while the debris is trapped in the bucket.
  • the aperture 20 returns to a close configuration to prevent debris and leaves from floating out of the bucket 10.
  • the bucket 10 is openable through a mid-line or split in the bucket or has an opening in the wall 11 , This allows the cover 18 to remain engaged with the walls 1 1 while still allowing for debris to be removed.
  • the walls are joined together at the base 12.
  • an aperture 20 in the cover 18 comprises a plurality of slots allowing ingress of leaves and debris with the water flowing into the interi or cavity 15 while acting as a one-way valve through the flexibility of the cover to prevent debris and leaves from floating out of the bucket 10 when the pool pump is not in use.
  • the centre of the cover 18 defines a recess 26 that dips below the plane of the rim 13 so as to extend towards the bucket 10. This may be contrasted with the centre of the cover 18 shown in figures 13 to 15, which defines a protmsion 27 extending above the rim 13 and away from the bucket 10.
  • Such varying geometries may be utilised to provide desired properties such as: the rate of closure of the aperture 20 when the flow of water into the bucket 10 is stopped; transitory suction effects generated as the centre of the cover 18 returns to its normal resting shape when the water flow stops; the longevity of the product in use; etc.
  • the bucket 10 and the cover 18 as illustrated in figures 16 to 19 are in two separable left and right hand parts (although each half of the cover 18 is respectively integrally formed with each half of the bucket 10).
  • Both the base 12 and the sidewalls 11 of the left and right hand halves of the bucket 10 have projections 28 that are received by corresponding recesses 29 in the other side so as to allow the two halves to releasablv interlock with each other.
  • the left and right hand halves of the cover 18 each include a projection 30 that is releasablv received into a corresponding recess 31 in the other side to releasablv interlock the two halves of the cover 18, This allows the user to interlock the left and right halves when installing this embodiment into the skimmer well.
  • the user may remove the bucket 10 from the skimmer well and disengage the two halves from each other to ease removal of the accumulated leaf material and debris and to aid de-clogging of the perforations.
  • the split that defines the left hand and right hand sides of the cover 10 also functions as the aperture 20 that allows leaf material and other debris to be received into the bucket 10 due to the water that is being pumped into the skimmer well.
  • the material of the pool strainer bucket 10 and particularly of the wails 1 of the bucket 10 and the or any cover 18 of the bucket is flexible.
  • the material is a flexible rubber polymer, or an elastomer such as thermoplastic polyurethane (TPU), or similar material.
  • TPU thermoplastic polyurethane
  • the selected material should have suitable resistance to the typical levels of UV, ozone and pH to which the bucket 10 and cover 18 are likely to be exposed in use. If necessary, additives may be added to the material during manufacture to impart suitable resistance. Additionally, the material is preferably selected for suitability with the chosen production method. For example, TPU is well suited to injection moulding, which is one of the preferred methods for producing the bucket 10 and the cover 18.
  • the flexibility is between 50 and 70 duro. In some forms the flexibility is between 55 and 65 duro. In some forms the flexibility is 45, 50, 55, 60, 65, 70, 75, 80 duro.
  • the flexibility or hardness is sufficient that the bucket and lid can flex under certain forces and reform when the forces are absent.
  • the walls 1 1 are crushable under human pressing force but reform when left.
  • the aperture slot 20 is openable under a flow force of water and returns to a closed configuration when the water flow ceases. When the user decides to de-clog the pool strainer bucket 10, it must be extracted from the pool system.
  • the user may thread an elongate member such as a stick, broom handle, hook, etc., through the handle 23. The user then pulls on the elongate member so as to pull the pool strainer bucket 0 out of the skimmer well. For embodiments such as those illustrated in figures 4 to 12, which do not have a handle, the user would simply reach into the water to extract the bucket 10.
  • an elongate member such as a stick, broom handle, hook, etc.
  • the flexibility of the material from which the embodiment is made allows the user to crush the pool strainer bucket 10, for example by stepping on it, so as to kill any such dangerous or undesirable life forms that may be residing within. Once the crushing force is no longer applied, the bucket 10 resiliently reforms and the user may now safely remove the bulk of the leaf matter and/or debris from the pool strainer bucket. Typically, however, some smaller pieces of leaves or other debris may remain stuck in some of the perforations.
  • the flexibility of the material assists with this step of the procedure because it allows the user to impact the pool strainer bucket 10 against a solid object such as the ground, a rock garden or the like.
  • the flexibility also allows the bucket 10 to withstand such impacts with little or no risk of fracturing as compared to the fracture risk associated with the comparatively rigid and brittle prior art buckets.
  • the flexibility of the material also allows the user to turn the pool strainer bucket 10 inside-out so as to assist in removal of leaf matter and/or debris from the perforations. This gives the user easy access to the side of the perforations that is usually on the inside the bucket.
  • the process of turning it inside-out also deforms the perforations, which may assist de-clogging. Once de-clogged, the user returns the bucket 10 to its normal configuration.
  • the de-clogging process can be further eased with the use of two pool filter buckets 10. This allows the user to remove a clogged bucket 10 and immediately replace it in the pool system with the second clean bucket. The user can then crush the removed bucket to kill any undesirables and then allow it to dry. Typically, once dried, the leaf matter and/or debris is easier to remove from the bucket and its perforations.
