Definitions

  • a separation wall comprising, at the level of the side intended to be in contact with the bottom wall, one or more breakable zones in order to retain or remove these zones depending on the positioning of the separation wall in the tank, and therefore depending on the presence or absence of protuberances at the level of the contact surface between the separation wall and the bottom wall of the tank.
  • this solution has the disadvantage of limiting the possible reuse of the separation wall between two waste collection bins having bottom walls of different shapes, or in the same collection bin but in a different position and not including the same positioning constraints.
  • the removal of the breakable zone(s) creates a space through which waste could be transferred from one compartment to another.
  • the invention aims in particular to provide a waste collection bin separation wall which can be used in different waste collection bins having different aforementioned positioning constraints, or in different positions in the same waste collection bin, each position having different aforementioned positioning constraints, and ensuring the aforementioned sealing.
  • FIG. 1 illustrating a separation wall 2 of a waste collection bin.
  • the separation wall comprises a main body 4.
  • This main body 4 forms almost the entire separation wall 2. It comprises a plurality of discontinuities 6 (a single discontinuity referenced on the figures 1 and 2 ) making it possible to stiffen the wall of separation 2.
  • These discontinuities 6 form depressions on the external faces of the main body 4.
  • discontinuities 6 arranged one opposite the other on opposite faces of the main body 4 come together, which makes it possible to stiffen the main body 4.
  • the main body 4 is preferably made of high density polyethylene. It is a material classically used to design waste collection bins, with optimal mechanical properties. As described below, the main body 4 can be made by blow molding. From then on, it forms a hollow body.
  • the main body 4 comprises four sides, three of which are intended to be in contact with internal walls of the tank, in order to separate the storage volume.
  • this particular structure could be put in place, alternatively or in addition to the example illustrated, on one or more sides of the separation wall 2 intended to be in contact with another wall of the waste collection bin.
  • the first side 8 comprises at least one recess 10 extending into the main body 4.
  • This recess 10 therefore corresponds to a local deformation of the separation wall 2 at the level of the first side 8.
  • the recess 10 has an arcuate shape. This shape is particularly suitable for interaction with a hemispherical protrusion extending from an internal face of the bottom wall of a waste collection bin.
  • Other forms of recess can be considered, advantageously a shape complementary to that of the protuberance.
  • the separation wall 2 comprises at least one sealing lip 12 which is elastically deformable and extends from the first side 8.
  • the illustrated example shows the presence of three sealing lips: a first sealing lip 12 (called subsequently “sealing lip 12") extending from the first side 8, but also two second sealing lips 12' and 12" extending from sides of the separation wall 2 intended to be in contact with the side walls of the waste collection bin It would also be possible for the same sealing lip to extend on several sides of the separation wall 2.
  • the sealing lip 12 is molded with the main body 4. This is a simple way of obtaining the separation wall 2.
  • the sealing lip 12 can be made in high density polyethylene, just like the main body 4. Concerning the sealing lip 12, the use of high density polyethylene contributes to obtaining a certain elasticity of the sealing lip 12.
  • the sealing lip 12 could be attached to the main body 4 after molding the latter, for example by gluing, or else be overmolded onto the main body 4. This makes it possible to choose a specific material for the sealing lip. 12 and different from that of the main body 4.
  • the sealing lip 12 comprises a first zone 14 extending into the recess 10 and projecting from the first side 8, the first zone 14 of the sealing lip 12 comprising at least one slot 16 (only referenced on the figure 2 And 3 ) extending from the first side 8 to a distal end 18 (ie furthest from the first side) of the sealing lip 12.
  • the sealing lip 12 comprises three slots 16, a slot 16 extending into the first zone 14 and two other slots 16 extending on either side of the first zone 14. This configuration makes it possible to optimize the deformability of the first zone 14 of the sealing lip 12 extending into the recess 10.
  • the slot 16 extends from a point on the first side 8 in a direction perpendicular to a tangent to the first side at this point. This is a preferential direction of extension of the slot 16 ensuring optimal deformation capacity. In the example illustrated, the three slots 16 extend in this direction.
  • the sealing lip 12 is inclined relative to a median plane in which the main body 4 extends. This configuration contributes to obtaining a sealing lip 12 which is sufficiently flexible so that it can fit form the protuberance, while being rigid enough to remain almost vertical in the air, and regain its initial shape when the separation wall 2 is removed from the waste collection bin, which allows it to be positioned in another location while ensuring the desired sealing function.
  • the thickness of the lip 12 is between 0.5 and 1 millimeter.
  • this helps to obtain a sealing lip 12 that is sufficiently flexible so that it can fit the shape of the protrusion, while being sufficiently rigid to remain almost vertical in the air as explained below. above.
  • the thickness of the sealing lip 12 it is possible for the thickness of the sealing lip 12 to decrease from the first side 8 to a distal end 18 of the sealing lip 12. We obtain a more easily deformable distal end 18 and an anchoring sturdy to the main body 4.
  • the separation wall 2 can be implemented using a mold comprising a main cavity allowing the molding of the main body 4 and at least one peripheral cavity adjoining the main cavity, of a height less than that of the main cavity, and allowing the molding of the sealing lip 12.
  • a mold comprising a main cavity allowing the molding of the main body 4 and at least one peripheral cavity adjoining the main cavity, of a height less than that of the main cavity, and allowing the molding of the sealing lip 12.
  • the first step of the manufacturing process consists of introducing a plastic parison, for example high-density polyethylene, into the open mold and then closing the mold.
  • a plastic parison for example high-density polyethylene
  • the parison, carried in the molten state can for example be tubular in shape.
  • the blown air makes it possible to force part of the plastic material to fill the peripheral cavity(ies), in order to form the sealing lip(s).
  • the slot(s) 16 are produced during the molding of the sealing lip 12 using a suitable shape of the mold around which the plastic material flows.
  • the size of the slot(s) 16 therefore depends on the shape of the mold and the size of the portion(s) around which the plastic material flows.
  • peripheral cavity(ies) make it possible to form a peripheral strip which does not have the desired shape of the desired sealing lip(s). In this case, and after molding, it is possible to cut this peripheral strip to form the sealing lip 12. This may involve automatic cutting using a knife. It is an element of elongated shape, placed around the peripheral strip and making it possible to delimit the sealing lip 12, which then allows easier cutting.
