Definitions

• the present invention relates to a system for opening / closing a lid and a waste container, in particular for infectious medical waste pointy or sharp edges, provided with such incubator.
• a first conventional system consists of a lid hinged in a hinge that the user manipulates above the opening of the container to unmask or otherwise leave free access to the orifice.
• Patent FR 2 494 231 discloses a container whose lid tilts inwards when the user pushes on it. The return to the closed position is ensured by the gravity, one of the sides of the lid being weighted so to orient its rotation in the direction of closing. Such devices cause a significant loss of the useful volume of the container, since the lid tilts inwardly thereof and furthermore have a risk of returning to the outside of the waste introduced by rebound on the lid if the opening of the latter was not completely achieved due to insufficient push of the user.
• the present invention therefore aims to provide an original system for opening / closing a lid to meet the legislative requirements, which is easy to use and economically advantageous to produce, given the single-use destination containers waste.
• the present invention relates to a system for opening / closing a lid comprising a flap pivotally mounted about an axis to close the orifice of said cover and actuating means for rotating the flap from its closed position to its open position and reciprocally, remarkable in that said actuating means comprise at least one pusher mounted on return means in position, said pusher having a bearing surface on which a thrust is exerted and a first and a second elastically deformable effectors each cooperating with an abutment arranged on the shutter so that a first push on the pusher brings the first effector into contact with a first stop and causes the flap in rotation from its closed or open position to its respectively open or closed position and a second thrust exerted on the pusher the second effector is brought into contact with the second abutment in order to drive the flap in rotation towards its initial position, the said actuating means further comprising a means of restoring assistance and stabilization, linking the cover and the flap, which is compressed during the initial phase of rotation of the flap and which relax
• the first and second effector are merged, the single effector alternately coming into contact with the two stops.
• the subject of the invention is also a waste container, in particular for pointy or sharp-edged medical or infectious waste, comprising a lid secured to a container, the lid being provided with the opening / closing system according to the invention.
• FIG. 1 is a perspective view of a garbage container having a lid provided with an opening / closing system according to the invention
• FIGS. 2A to 2F are schematic cross-sectional views of the lid illustrating the kinematics of the opening / closing system according to the invention.
• the subject of the invention is a container 1 for infectious waste comprising a lid 2 secured to a container 3, this lid 2 being provided with an original opening / closing system the detailed description of which will follow.
• the lid 2 comprises a flap 4 pivotally mounted and two pushers 5a_, 5b for pivoting the flap 4 from its closed position to its open position and vice versa.
• the cover 2 will be provided with two pushbuttons 5a, 5b flanking the flap 4 on either side of its width in order to allow ambidextrous use of the system.
• the waste container comprises a needle-removing plate which is disposed in the hole of the lid, which is covered by the flap.
• the cover 2 comprises actuating means which comprise at least one pusher 5a, 5b mounted on return means 6 in position, said pusher being provided with a visible face of support.
• This pusher 5a, 5b comprises in the variant shown two effectors 7, 7 'elastically deformable. Preferably, it will be flexible tongues.
• the first and second effectors are merged, that is to say that each pusher comprises a single effector 7.
• the two-effect variant is preferable for the simplification of the kinematics and the reasons for deformation and less stress effectors.
• the shutter 4 is pivotally mounted about an axis 8 on the orifice of the cover 2.
• this axis 8 slides along a slideway 9 arranged in the cover 2, so as to reduce the size of the flap which is positioned in a housing 10 designed for this purpose when in the open position.
• the flap 4 thus rotates in translation along the slide 9 when it is open or closed.
• the flap 4 also comprises two stops 11, 11 'each cooperating respectively with an effector 7, 7' of the pusher 5a, 5b.
• the two abutments cooperate alternately with it.
• the angular positioning and the shape of the stops will vary according to the configuration of one or two effectors of the pusher.
• the abutments 11, 11 ' consist of two semi-tubular grooves which extend outwards towards the side walls of the lid 2.
• the push button 5a, 5b is disposed on the upper face of the cover so that the thrust is exerted downwards, and that its projection remains inscribed in the bearing surface of the base of the container on which the cover is mounted. That is, the thrust is exerted in a generally vertical direction when the lid is mounted on a flat-bottomed container placed on a horizontal surface.
• This feature advantageously contributes to the stability of the waste container during the waste disposal operation and allows it to be made with one hand, without the need to hold the box with the other hand to prevent it from falling during the opening of the lid, since the thrust is exerted downwards.
• the flap 4 comprises a cam 13 which is in direct contact with a fixed roller 14 of the cover 2 and which allows the guiding of the flap during pivoting.
• a means of return 15 assistance and stabilization links the cover 2 to the flap 4, here at the wing 12, so as to accompany and assist the evolution of the component 4 and exert its thrust on the latter by pressing one of the abutments 11, 11 'when the flap 4 is in the closed position as shown in Figure 2D.
• This return means 15 is almost completely relaxed when the flap 4 is in one of its rest positions and is compressed during the initial phase of rotation of the flap, triggered by the thrust on the pusher 5 which drives the flap 4 in rotation by leverage.
• the rotation of the shutter reaches a point of equilibrium that the accumulated kinetic energy combined with the restitution of energy provided by the relaxation of the return means 15 allows to pass, hence the assistance function of the latter.
• This return means 15 also makes it possible to maintain the flap 4 when it is in an open or closed rest position and thus to avoid an unexpected opening or closing when the container is not being handled. open or close it.
• the biasing means will be dimensioned (size and stiffness constant) so that it exerts a sufficient thrust being almost completely relaxed to maintain the flap when it is in the rest position.
• the device is in a closed position in FIG. 2A: the pusher 5a., 5b is in the rest position, the first effector 7, called the opening effector, being positioned unconstrained in the first groove 11, while the second effector 7 ', said closing effector, is completely free.
• the biasing means 15 assistance and stabilization bears on the second groove 11 '.
• the user wants to open the lid 2, it exerts a downward pressure (arrow A Figure 2B) on one of the two pushers 5a, 5b, in order to bring it closer to the upper face of the lid 2.
• the first effector 7 will exert a bearing on the first groove 11 which will cause the flap 4 downwards and initiate its pivoting about its axis 8 which translates into the slide 9.
• the return means 15 assistance and stabilization compressed during the first part of the rotation, gradually relaxes, pushing the flap 4 towards its second rest position, in its housing 10.
• the first effector 7 is no longer in position. contact with the first stop 11 and the return means 15 is almost completely relaxed and exerts a stabilization constraint that keeps the flap 4 in position.
• the user releases his pressure on the pusher 5a., 5b which returns to its rest position by means of the return means in position 6.
• the second effector 7 ' positioned against the second stop 11 '.
• the user exerts a downward pressure (arrow A ' Figure 2E) on the pusher, which is transmitted by the second effector 7' on the second groove 11 'and causes at this time the flap 4 pivoting to its closed position.
• the release allows the pusher 5a_, 5b to return to its initial position, again thanks to the return means in position 6, and the first effector 7 is positioned against the first stop 11 to be able to start an opening cycle / closing.
• the means of return 15 assistance and stabilization accompanies the movement of the flap 4 and ensures its maintenance in the closed position, after being compressed during the push.
• all the parts constituting the opening system is made by injection molding of plastics (synthetic polymers).
• All return means will therefore advantageously consist of flexible tongues. It is easy to understand the considerable advantage provided by this assisted opening / closing system, in which on the one hand the effectors making it possible to transmit the power of the thrust exerted are not subjected to stress that during the opening phase for one and closing for the other, and secondly the return means in the position of the pusher and assistance movement are compressed only during the phase of thrust, all the means undergoing no stress, or very low, when the flap is in one of its rest positions, open or closed: the elastic memory of the materials is little solicited, which greatly reduces their wear.
• This design advantageously makes it possible to produce a system with a minimum number of mechanical parts, when the system is produced according to the injection molding technique: the cover 2, the shutter shutter 4 and at least one pusher 5a, 5b.
• the system may comprise an intermediate travel stop of the translation of the pusher 5a., 5b or friction means for partially opening the flap 4 in a position between that shown in FIGS. 2B and 2C, the biasing means 15 assistance and stabilization then exerting a thrust to bring the flap 4 to its initial closed position.
