Description

Technical area

The present invention relates to an improvement of temporary closure filling lid for a container for collecting and transporting infectious or toxic products intended for hospital and medical environments, said filling lid being integral with the main lid of the container or one of its walls and to easily introduce the waste without opening said main cover.

Prior art

In the field of containers for collecting infectious products intended for hospital and medical environments, containers with a parallelepipedal or cylindro-conical body, provided with a main lid provided with a peripheral groove provided with an elastic seal, are well known. sticky which fits on the upper edge of the body to seal the closure and a recessed circular opening in the cover may accommodate a circular lid called temporary closure filling. Generally, the circular lids of these containers allow their progressive filling by providing a first temporary closing position and then, when the container is filled, a second definitive closure position advantageously sealed. In this regard, the outer peripheral wall of the filling lid and the outer peripheral wall of the recessed opening are provided with a set of cams which cooperate to lock the filling lid by its rotation in the recessed opening.

A collection container for infectious products of this type is proposed in European Patent EP 0 629 169 which describes cams positioned on the outer peripheral wall of the lid and constituted by flexible hooks which cooperate with cams of the outer peripheral wall of the opening, that is to say the wall of the recessed opening visible by the user when the lid is not introduced, said cams being arranged in rows and extending perpendicularly to the outer peripheral wall of the opening, at different heights relative to the axis of rotation of the lid. The final closure of the circular cover is obtained by the particular arrangement of the cams at different heights or by the shape of the cams of the outer peripheral wall of the cover and / or the cams of the outer peripheral wall of the opening which include indentations preventing any movement of said lid after its closure.

This type of locking means of the circular cover in the recessed opening have the disadvantage for the user to operate, both for opening and closing, a succession of movements that require the use of both hands. which is particularly delicate when the user wants to introduce waste that he already holds in one of his hands. Moreover, these containers do not allow to obtain the seal of their temporary closure thus causing insecurity for users until their final closure.

To overcome these drawbacks, a container for collecting infectious products such as that described in patent application FR 2 8 04 0 94 filed in the name of the Applicant is already known. Said collection container comprises a body closed by a main lid provided with a circumferential groove provided with an elastic seal which fits over the upper edge of the body to seal the closure and a recessed opening made in the main cover capable of accommodating a filling cover, the outer peripheral wall of the filling cover and the outer peripheral wall of the recessed opening having cooperating means for locking by rotation of said filling cover in the opening, the hollow opening being a truncated cone section decreasing from the main cover to the inside of the body and the filling cover having a truncated cone section homothetic to that of the recessed opening and adapted to fit in said recessed opening.

However, this type of collection container has the disadvantage of not having a filling cover permanently secured to said container. Indeed, once opened, to allow the introduction of waste in the container, the filling cover must be removed from the collection container and placed on a support, the filling cover can then contaminate the support on which it was placed . In addition, the filling lid can also be damaged in the best case, or even lost, which would result in making the collection container unusable.

Presentation of the invention

The object of the present invention is therefore to overcome the drawbacks mentioned above and to propose a device for permanently securing a filling cover intended to be locked temporarily or permanently in a recessed opening made on an outer wall of a container. intended primarily for the collection and transport of infectious or toxic products from hospital and medical environments. For this purpose, the present invention relates to a device for securing a filling cover on an outer wall of a container provided with a recessed opening capable of receiving said filling cover, the outer peripheral wall of the cover. and the outer peripheral wall of the recessed opening having at least one locking lug and a helical cam cooperating for rotational locking about its central axis of symmetry respectively of said filling cover in the recessed opening. outer peripheral wall of the recessed opening having at least one opening for the passage of said locking tab and the opening of said filling cover, said device comprising fastening means cooperating with each other to enable the filling cover to be secured to the outer wall when opened by pivoting about a parallel axis the said outer wall, while also allowing its locking in the recessed opening by rotation about said central axis of symmetry, when the locking tab is engaged with the cam, said device being remarkable in that the securing means advantageously comprise a tongue disposed on the top of the filling lid and opposite the locking lug and two elements forming a clevis determining said pivot axis for the opening of the filling lid, and arranged projecting on said outer wall and vis-à-vis said breakthrough and in that the tongue has a free end in the overall shape of T and therefore comprises a rod of generally circular cross section extending substantially perpendicular to both sides of its free end and the elements each comprise an orifice, said orifices being coaxial and their longitudinal axis being globally perpendicular to the central axis of symmetry of the filling lid and forming the pivot axis, said rod being adapted to be inserted into said openings to allow the opening of the filling lid. One of the elements preferably comprises a slot passing through the orifice and opening on one side in said orifice and the other on the outside of said element, said slot allowing the passage of the tongue during the opening. insertion of its stem into the two orifices. The subject of the invention is also a container for collecting and transporting infectious or toxic products, comprising at least one outer wall provided with a recessed opening capable of receiving a remarkable filling lid in that it comprises a device for solidarization according to the invention.

BRIEF DESCRIPTION OF THE FIGURES Other advantages and features will become more apparent from the following description of an embodiment of a fastening device according to the invention, with reference to the appended figures in which: FIG. perspective view of a filling lid secured to the main lid of a container for collecting and transporting infectious or toxic products by the securing device according to the invention, - Figure 2 is an enlarged detail view of the FIG. 3 is a top view of the main cover of FIG. 1; FIG. 4 is a view from above of the filling cover of FIG. 1; FIGS. overviews showing the different relative positions between the filling lid and the main lid of the container of Figure 1.

Best way to realize the technical invention

In this non-limiting example, there will be described a device for securing a filling lid on the outer face of a main lid, the latter being provided with a recessed opening and able to receive said temporary closure filling lid. or definitive. Said main lid is able to be sealed to the upper edge of the body of a container of generally parallelepiped shape and intended for the collection of infectious products.

However, said hollow opening, opening on one side in the container and on the other side outside said container may be made directly in one of the walls of the parallelepiped body of said container, depending on its end use, without departing from the scope of the present invention, the securing device will then to secure the filling cover on the outer face of the wall associated with said recessed opening.

Here the term "outer face" refers to the face of an element which is outside the container under normal conditions of use and "inner face" the opposite face of said element.

Thus, with reference to FIGS. 1 to 4, there is shown a main lid 1 adapted to be secured, in a sealed manner, on the upper edge of the body 2 of a container 3 of generally parallelepipedal shape and comprising in the central part of its external face 4 a hollow opening 5 generally circular adapted to accommodate a filling cover 6.

The filling lid 6 comprises gripping means constituted by a handle 7, advantageously ergonomic, extending diametrically between the edges of said filling lid 6. The recessed opening 5 and / or the filling lid 6 are preferably truncated cones of decreasing section from the main cover 1 to the inside of the container body, homothetic or not, so that said filling cover 6 is adapted to fit in said recessed opening 5. Such a truncated cone configuration allows self-centering of the filling lid 6 in the recessed opening 5 thus facilitating its introduction.

Furthermore, the outer peripheral wall of the filling lid 6 or the outer wall of the recessed opening 5 advantageously comprise sealing means cooperating with complementary means disposed respectively on the outer wall of the recessed opening 5 or on the outer wall of the filling cover 6 to ensure a seal when locking the filling cover 6 in the recessed opening 5.

In addition, the outer peripheral wall of said filling cover 6 and the outer peripheral wall of the recessed opening 5 have locking means which make it possible to provide temporary closure and then definitive closure of said filling cover 6.

Said locking means consist of at least one locking lug, not shown, generally perpendicular to the centrally symmetrical axis A6 of said filling cover 6, integral with the outer peripheral wall or the bottom of the latter, cooperating with a 8 helical cam extending at the lower end of the recessed opening 5 in a direction generally parallel to the axis A6 of the filling cover 6, the recessed opening 5 comprising along its outer peripheral wall at least a vertical breakthrough 9 to allow the passage of said tab of the filling cover 6 and thus allow the opening of said filling cover 6.

For further information concerning the shapes, the sealing means, the complementary means and the locking means of the recessed opening 5 and the filling cover 6, reference will be made to the European patent application EP 1 12 0 091 filed in the name of the Applicant.

In accordance with the invention and with reference to FIGS. 1 to 4, the container comprises a device 10 for securing the filling lid 6 to the main lid 1. This device 10 for securing comprises securing means allowing, on the one hand, to act as a hinge when opening the filling cover 6 by pivoting about a pivot axis parallel to the outer wall 4 of the main cover 1 while ensuring the fastening of said filling cover 6 on said outer wall 4 and on the other hand, to rotate the filling cover 6, about its centrally symmetrical axis A6, to ensure its temporary closure and its final closure.

Said securing means comprise a tongue 11 generally perpendicular to the axis A6 of the filling cover 6, secured to the top of the latter, cooperating with two generally parallelepipedal elements 12 and 13 secured to the outside surface 4 of the main cover 1 and substantially parallel to each other so as to form a yoke 15 determining the pivot axis A15 parallel to the outer wall 4, for the opening of the filling lid 6. The two elements 12,13 are arranged vis-à-vis of the breakthrough 9 arranged on the outer peripheral wall of the recessed opening 5 (see FIG. 3), that is to say that they are arranged symmetrically with respect to the plane of symmetry of said breakthrough 9 and that opposite of the latter. The two elements 12, 13 are preferably arranged in close proximity to the recessed opening 5.

Said tongue 11 is disposed on the filling cover vis-à-vis the locking tab and therefore extends along the longitudinal axis of the locking tab, but in the opposite direction to the latter. In addition, said tongue 11 has a free end in the overall shape of T and therefore comprises a rod 14 of generally circular cross section extending substantially perpendicularly to either side of its free end (see Figure 4).

The elements 12, 13 each comprise an orifice 16 respectively 17, whose longitudinal axis is generally perpendicular to the axis A6 of the filling cover 6. The two orifices 16, 17 are coaxial and their longitudinal axis forms the pivot axis A15 and their cross sections are identical and homothetic to that of the rod 14 of the tongue 11 so as to ensure the insertion of said rod 14 into the two orifices 16, 17 in order to create a hinge to allow the opening of the lid. filling 6 by pivoting about the longitudinal axis of said rod 14.

It is well understood that the rod 14 of the tongue 11 is inserted into the two orifices 16, 17 by rotation of the filling lid 6 around the axis A6 of central symmetry. For this, the element situated on the side by which said rod 14, here the element 12, is inserted has a slot 18 passing through said element 12 along the orifice 16 and opening on one side into said orifice 16 and the other outside said element 12. This slot 18 allows the passage of the tongue 11 during the insertion of the rod 14 of the tongue 11 in the two orifices 16,17, during the rotation of the filling cover 6.

With reference to FIGS. 1 to 7, the securing device 10 is such that, when the locking lug cooperates with the cam 8 of the recessed opening 5, that is to say that it engages with said cam 8, the filling cover 6 must be rotated around the axis A6 in the direction R (see FIG. 5) in order to return the tongue 11 towards the elements 12, 13, until the rod 14 of said tongue 11 is fully inserted into the openings 16,17, as shown in Figure 2. The locking tab is then in line with the piercing 9 arranged on the inner wall of the recessed opening 5 and can therefore easily open the filling cover 6 by rotating it around the pivot axis A15.

The locking tab, the breakthrough 9, the tongue 11 and the elements 12, 13 of the securing device 10 are dimensioned such that: - when the filling cover 6 is in a position, represented in FIG. 6, in which the filling cover 6 is inserted into the recessed opening 5 and the rod 14 of said tongue 11 is fully inserted into the orifices 16, 17, and said filling cover 6 is rotated around the axis A 6 in a direction opposite to the direction R, the locking lug engages as soon as the rod 14 is disengaged from the orifice 16, - when the filling lid 6 is in a position, represented in FIG. 7, in which the rod 14 of said tongue 11 is fully inserted into the openings 16,17 and the filling cover 6 is out of the recessed opening 5, said filling cover 6 can not be detached from the outer wall 4 of the cover e main 1.

Thus, when the filling lid 6 is in the position shown in FIG. 5 in which the locking tab of said filling lid 6 cooperates with the cam 8 of the recessed opening 3, the filling lid 6 can then be either temporarily or permanently locked, is pivotally opened about the pivot axis A15. However, whatever the chosen option, the filling lid can no longer be detached from the outer wall 4 of the main lid 1.

To facilitate, the establishment and use of the filling cover 6, the outer wall 4 has pictograms 20,21,22,23 (see Figure 3).

Thus, to set up the filling cover 6, it is present above the recessed opening 5 by positioning its tongue 11 in front of the pictogram 20, then it is pressed until its locking tab cooperates with the cam 8 of the recessed opening 5, that is to say that it is engaged with said cam 8.

Then, to open the filling cover 6, it is rotated about its axis A6 to position its tongue 11 in front of the pictogram 21. In this position, the rod 14 of said tongue 11 is fully inserted into the holes 16, 17 , and then said filling cover 6 can be rotated around the pivot axis A15.

Moreover, to lock the filling cover 6 temporarily then permanently, it is rotated about its axis A6 to position its tongue 11 in front of the pictogram 22, then the pictogram 23. The skilled person will have no difficulty to dimensioning the various constituent elements of the solidarity device 10, in particular the spacing of the elements 12, 13 and the slot 18, mainly as a function of the locking lug and the breakthrough 9 of the recessed opening 5.

Finally, it is understood that the elements 12,13 may form a single piece without departing from the scope of the present invention.

Possibilities of industrial application

The fastening device 10 according to the invention applies more particularly to the filling lid of a container for collecting and transporting infectious or toxic products, but can also be adapted to all types of containers and the like.

Finally, it goes without saying that the present invention is not limited to the preferred embodiment and implementation described, but that it can be modified or adapted according to the needs or special requirements, without departing from the scope of the invention.
