- the invention relates more particularly to a device for sealing off the access port of containers and for purifying the ambient air therein by means of opening and closing cycles, these containers being intended for the packaging of products sensitive to gaseous pollutants.
- This sealed obturation and purification treatment device is composed, according to a new combination of means known or not:
- the sealing shutter and purification treatment device being made of thermoplastic materials by the means of plastics, in one piece.
- the gaseous pollutants which may be present in the ambient air in the sealed containers for packaging sensitive products can be, for example, water vapor, oxygen (0 2 ), ammonia ( NH 3 ), alcohols, aldehydes, ketones, sulfur dioxide (S0), hydrofluoric acid (H 2 S), mercaptans, alkenes including in particular ethylene, alkynes, carbon dioxide carbon (C0 2 ), carbon monoxide (CO), nitrogen dioxide (N0 2 ), alkanes including in particular methane (CH 4 ), halogens including in particular fluorine, bacteria suspended in l ambient air and others.

- materials sensitive to pollutants as mentioned above to be packaged in a sealed container are in general, medicinal products, in particular effervescent ones, which it is desirable to protect so that their reactive efficacy does not change by: reaction with at least one of the polluting agents, and / or for: their physical integrity being preserved over time and that is avoided, for example, a change in their mechanical cohesion.
- Objects sensitive to pollutants, to be packaged in a sealed container are in particular oblong in shape, have a substantially polygonal, circular, elliptical, elongated section and are consumable.
- Such objects are in particular tongues, test strips or rigid strips used for example for diagnostic or control purposes in the medical field, dressings, food products such as chewing gum, toothpicks, sticks or other.
- caps to close containers whose essential function is to be desiccant: these particular containers are intended to receive and contain products sensitive to ambient humidity, products which must be protected by creating the driest internal ambient atmosphere possible, to prevent them from regaining moisture, because: such resumption humidity by adsorption could in particular react with said products by reducing their reactivity, causing their mechanical brittleness upon impact, their disintegration or their disintegration in the container.
- Products which are particularly sensitive to ambient humidity are numerous and may more precisely be, for example, test drug materials which are in powdered forms or in more elaborate forms such as granules, tablets, lozenges, objects of oblong shape such as strips for tests or others, including those more specifically which have a particular sensitivity to humidity.
- These desiccant and waterproof containers of the state of the art for the storage of products sensitive to ambient humidity are of tubular shape or of another shape and, provided with an orifice, are closed by a stopper made integral or not of the tubular part by means of an attachment means such as a narrow flexible strip made of a polymer material identical to that of the container and the stopper.
- desiccant and waterproof containers are provided with internal desiccant means which are either a coating or an insert produced by means of a desiccant thermoplastic polymer composition, placed inside the containers on the internal surface of the bottom of the tube and / or on the internal surface of the side wall of the tube, or else a granular desiccant material placed in a special housing on the internal surface of the stopper.
- internal desiccant means which are either a coating or an insert produced by means of a desiccant thermoplastic polymer composition, placed inside the containers on the internal surface of the bottom of the tube and / or on the internal surface of the side wall of the tube, or else a granular desiccant material placed in a special housing on the internal surface of the stopper.
- desiccants are located separately or simultaneously to increase the effectiveness of their dehydrating action by a mass effect.
- a closure means which can be a removable plug fitting into the open end of the tubular casing, or a cover cap also fitting into the open end, but connected to the casing tubular by a flexible connection such as a narrow flexible polymer strip acting as a hinge.
- thermoplastic polymer compositions according to techniques well known in the plastics industry.
- Means for closing the containers and the desiccant containers closed by these means, for packaging materials and / or objects sensitive to ambient humidity, are described in the prior art and are essentially distinguished from one another by their architecture, in particular by the desiccant means used in said containers and by the architecture of the means for closing the container.
- this first type of closure is a plug-cover of the male type connected to the tubular part of the envelope of the desiccant container by means mechanical composed of a ring encircling. forces said tubular casing and a flexible and narrow connecting strip between the cap-cover and the ring, the desiccant container being formed by a tubular casing open at one of its ends to give access to the receptacle zone.
- a document (US P 4,934,556) describes such a closure means and a desiccant container, closed by this means, the closed assembly forming the container consisting of: "a closure means comprising, a cap-type cover male, of a ring for the forced mounting of said cap-cover on the tubular envelope of the container, of a tamper-evident indicator, to be torn, connecting the mounting ring to the external periphery of the cap-cover and of a flexible strip acting as a narrow hinge connecting the cap-cover and said ring, the sealing means being made of a thermoplastic polymer material, which may be different from that of the tubular casing.
- the plug-cover of the male type is formed by a bottom and a descending peripheral skirt called external which delimit a cylindrical cavity inside which is a housing containing a pulverulent desiccant, in direct contact with the gaseous medium internal to be dehydrated.
- the closure means comprising the cap-cover, the strength mounting ring, the tamper-evident seal and a single flexible and narrow connecting strip connecting the cap-cover to the ring constitutes an assembly made of thermoplastic polymer material, independent of the tubular envelope forming the receptacle of the desiccant container.
- This type of desiccant cap-lid intended to close a tubular envelope used for packaging moisture-sensitive products presents uncertainties as to its ability to ensure rapid and complete drying of said products during the opening / closing of said packaging container. . This state of affairs seems:
- cap-lid requires two-way manipulation of the closed container, both for its opening and its closure.
- this other type of closure is a plug-cover of the female type, secured to the envelope of the desiccant container by means consisting of a flexible and narrow connecting strip, the tubular casing, the cap-cover and the connecting means being produced by injection with the same thermoplastic polymer material.
- a document (EP 1 352 844) describes such a type of means for closing the desiccant containers, the closed assembly forming the container consisting of: • a tubular envelope of thermoplastic polymer material provided with a bottom at one of its ends and open at the other end,
- a plug-cover of the female type, free of a descending internal skirt, which covers in the closed position, the wall of the open end of the envelope of the container, the sealing being capable of being ensured by contact the internal surface of the bottom of the lid of the cap-lid with the periphery of the open end of the tubular casing, said cap-lid, being provided on its internal surface with an perforated cavity capable of receiving a desiccant in tablet form and connected to the envelope by means of a link made of a flexible and narrow strip of polymer, the envelope, the cover and the link between the cover and the envelope being a single piece, produced in a single plastics processing operation, by injection-molding for example,
- a desiccant insert formed of a thermoplastic polymer material loaded with desiccant materials, this insert can simultaneously cover the bottom and the internal wall of said enve ⁇ r ⁇ ppe.
- the cap-cover devoid of a descending peripheral internal skirt cannot establish a surface-to-surface type seal with the internal surface of the open end of the tubular casing, the seal can only and apparently only be obtained by contact with the surface internal of the bottom of the cap-cover and the periphery of the open end of the envelope.
- the cap-cover is not particularly suitable for creating a seal between the interior and the exterior of the container, by its very architecture, but also by its flexible connection means with the envelope, means which does not make it possible to position the cover at the time of its closure because of this great flexibility and therefore, the absence of sufficient mechanical rigidity both longitudinally and laterally, necessary for guiding the cover-cap at the time of its closure .
- GB 2 224 309 describes a hinged closure device, that is to say a cap for thermoplastic containers and more particularly for containers having a very narrow, coaxial distribution orifice, intended for the distribution of liquid.
- the stopper comprises on the internal surface of its upper end a tubular peripheral wall having a section adapted to that of the narrow dispensing orifice to be closed, and allowing, when the stopper is in the closed position, to simultaneously seal the plug.
- Said device consists of two parts, the first part being a snap-on cover, pivoting on two hinges constituted by two flexible bands, defining a first axis of rotation, the second part being a base to be fixed on the mouth of a container to be closed, and a flexible and elastic link, ensuring the connection between these two members and allowing the plug to occupy two rest positions, one closed and the other open, located on each side of an intermediate position during movement.
- Said flexible link having a recall function, is in the form of an "S" and is connected on one side to the stopper at a precise point and on the other, to the external surface of the base at another precise point, and this, in a semi-rigid elastic manner.
- this device has certain drawbacks which can result from a form of embrittlement of the material constituting the flexible link.
- the "S" shape taken by the flexible link when the device changes from a closed position to an open position contributes to creating two opposing forces with respect to an inflection point which is situated substantially in the middle of the flexible link. , this inflection point delimiting downstream a convex blade zone and upstream a blade zone which remains concave.
- the means which combined together, ensure: • easy opening / closing of the sealing shutter and processing device by precise mechanical guidance of the shutter means so that the shutter is done precisely without manual guidance, according to an excellent positioning,
- the device for the sealed obturation and for the purification treatment of the ambient air therein of containers for packaging products sensitive to ambient pollutants, with amplitude of the controlled opening angle, and with mechanical opening and closing assistance, made of thermoplastic polymer materials device to be installed on the tubular casing of the access orifice of said containers, which comprises: means for sealing the access orifice of the container, having on its internal face means for conditioning ambient air treatment agent (s), means for mounting the sealing means on the tubular casing of the access orifice, a connecting means between the sealing means and the mounting means, a tamper-evident means with first opening, placed between the sealing means and the mounting means,
- a plug-cover of the male type consisting of an upper end wall on which is mounted a first coaxial peripheral wall establishing a tight contact with the internal surface of the tubular envelope of the access port of the container, and a second wall, internal to the first, constituting the means for conditioning ambient air treatment agents,
- a means of mechanical assistance in opening and closing and of controlling the amplitude of the opening angle of the shutter means placed in the space between the two hinges and linked simultaneously to the plug cover by a film hinge and to the device fixing ring on the envelope by another film hinge, said mechanical assistance means having the cross-sectional appearance of a square.
- the effectiveness of the sealing means in terms of sealing between the long frequency opening / closing cycles to prevent gas / gas exchanges between the inside and the outside of the closed container which could - cause an evolution the relative humidity rate and the rate of other gaseous pollutants prevailing inside the container.
- the obturation and purification treatment means created for the container is of the male type, as recommended by the state of the art, but is very different from the state of the art by the fact that its new architecture provides it with a peripheral zone of intimate contact with the internal surface of the tubular envelope constituting the orifice of the container to be closed, this intimate peripheral contact zone, of surface-to-surface type, forming an effective barrier for obtaining and maintaining the internal tightness of the container.
- the sealing means chosen is of the cap-lid type, comprising an upper end wall constituting the ceiling of the cap-lid having a section adapted to that of the tubular envelope which it must close.
- This upper end wall is provided with two walls, one said external and the other said internal, which are peripheral and tubular, concentric and coaxial with the tubular envelope.
- the first wall called external, peripheral and tubular wall, creates an intimate peripheral contact zone for obtaining sealing, of surface-to-surface type, by the establishment of a sealing barrier between the internal face of the tubular casing of the access orifice and the external face of said first wall, called external wall, of the cap-cover.
- this first wall reveals a peripheral bulge, oriented towards the outside, and intended to be in contact with the internal wall of the tubular envelope of the orifice of the container.
- the peripheral bulge of the first wall comes into force contact with the internal surface of the tubular envelope of the orifice, undergoing preferentially a certain deformation or crushing effect which causes an increase in the contact surface of the peripheral bulge with the internal surface of the tubular envelope of the container orifice so that the surface to surface contact which is tangential approach can become intimate and immediate upon closure by an increase in the contact surface which results from sliding and crushing from one wall to the other, reinforcing the seal between the closure device and the container.
- the second wall constitutes a suitable housing for receiving one or more purification treatment agents, the particular position of this housing being decisive for increasing the kinetics of treatment of gaseous pollutants and in particular the water vapour.
- This suitable housing preferably of the tubular type, is located on the internal face of the sealing means or cap-cover, and is closed by a means of closure which is not impermeable to gaseous pollutants to ensure their rapid elimination from the container in which are conditioned. sensitive products to protect.
- the desiccant agent used in the container closed by the sealing and treatment means is chosen from the group consisting of silica gels, the molecular sieves being in powdered form or deposited. on a powdery support.
- the container closed by the sealing and treatment means according to the invention is also very effective with regard to gaseous pollutants other than water vapor, known treatment agents suitable for each pollutant , are implemented in the appropriate housing created on the internal bottom of the sealing and treatment means:
- the flat lower edge of the external peripheral wall can be extended by a gripping visor.
- a safe opening system with regard to children in order to make it difficult or impossible for them to open the cover cap can be installed in line with the visor.
- This device which can be for example a flexible blade forming an integral part of the mounting means is placed below the visor so that the protrusion of the visor allowing to exert a vertical thrust to assume its opening is faired by this flexible blade. Therefore access to the visor can only be done after having exerted pressure on this blade in order to cause deformation and free access to said visor.
- the protection of the child is ensured by the necessary realization of two complementary gestures, and to be exercised simultaneously, the first gesture being a horizontal pressure on the flexible blade, the second being a vertical pushing action from bottom to high on the exposed visor, thanks to the maintenance of pressure on the flexible blade.
- the internal face of the external wall of the cover cap substantially in line with the gripping visor and the external face of the external wall of the tubular casing of the access orifice - of the container are provided with a latching means, requiring mechanical effort both to complete the closure of the plug-cover with reinforced sealing and to ensure its opening.
- the means for mounting the closure means or cap-cover is formed by a fixing ring which is mounted on the tubular casing of the access opening to the container to be closed, this ring: - having a dimensioning adapted to that of the tubular envelope, - being provided on its internal face, intended to be in contact with the external surface of the envelope of a snap-in or raised latching means, with respect to the external face of the envelope, on which the means allowing the latching of the ring is opposite, that is to say in relief or in hollow.

- the external peripheral surface of the tubular casing of the access opening to the container to be closed comprises two projecting peripheral flanges, separated from each other by creating a groove having a section a substantially rectangular shape, such that: • the thickness of the tubular envelope inside the groove is not modified, and that • the fixing ring comes to be forced into said groove.
- a peripheral groove which can have a substantially rectangular, hemispherical or hemielliptic shape in section, is hollowed out in the thickness of the wall of the tubular envelope of the container so that: the thickness of the tubular envelope inside the groove is modified, and is less than that of the tubular envelope and that • the fixing ring is forced to be mounted in said groove.
- the internal surface of the fixing ring has latching means which, when said fixing ring is force-fitted into the groove of the tubular envelope of the container, itself equipped with complementary latching means, are fitted into the corresponding latching means in order to block any rotation or translation of the plug relative to the container.
- Said latching means present on the internal surface of the fixing ring and on the internal surface of the groove of the container can be of various types such as grooves, grooves or the like.
- a relatively rigid hinge-type connecting means is present between the sealing means (or cap-cover) and the mounting means (a fixing ring) on the tubular casing of the orifice. access to the container.
- the hinge-type connecting means is formed by two film hinges spaced from each other, and giving rigidity to the connection between the cap-cover and the fixing ring, due of their spacing.
- Each film hinge is formed of two parts connected together by a polymer film playing the role of an axis of rotation allowing the opening / closing cycles of the shutter means, one of the parts being integrated by means of obturation, the other part being integrated with the mounting means.
- each of the two hinges integrated into the shutter means and into the mounting means constitute brackets for fixing the two film hinges to the shutter means and the mounting means.
- the means of inviolability or even witness of inviolability is formed: either of micro-links connecting the lower peripheral surface of the cap-cover to the upper peripheral surface of the fixing ring, these micro-links being micro-points of connection, independent of each other but forming a peripheral ring gear of connection between the desiccant closure means and the means of mounting on the tubular envelope of the orifice of the container, micro-points which are broken during the first opening by the application of a breaking force exerted on the visor in the bottom-up direction, that is to say of a tamper-evident ring to be torn off connecting the lower peripheral surface of the cap-cover to the surface peripheral device superior to the fixing ring,
- a mechanical spring-effect means for assisting with the opening or closing of the sealing and treatment shutter means is placed in the space situated between the two film hinges mentioned above.
- This mechanical means has the appearance in section of a square whose angle is of the order of 90 °.
- This mechanical spring effect means for assisting with the opening and closing of the sealing and processing means also controls the amplitude of the opening angle of the sealing means, so that, as soon as that it is at the end of its opening stroke, the closure means is easily driven in the closing direction by a finger of the same hand holding the container provided with the device according to the invention.

- the peripheral bulge (14) of the first wall (11) comes into force contact with the internal face (13) of the tubular envelope of the orifice, in undergoing a certain deformation and crushing effect which causes an increase in the contact surface of the peripheral bulge (14) with the internal face (13) of the tubular envelope, the surface-to-surface contact becoming total, intimate and immediate to closing by sliding and crushing the wall (11) on the wall (13) creating a complete seal.
- the second wall constitutes a suitable housing (15) for receiving a treatment agent for gaseous pollutants, in particular a desiccant, the particular position of this housing being decisive for increasing the kinetics of elimination of said gaseous pollutants.
- This suitable housing (15) is located on the internal face of the cap-cover, and is closed by a non-gas-tight closure means to ensure the rapid treatment of the ambient gaseous atmosphere and the elimination of pollutants in the atmosphere. with regard to sensitive products packed in the container.
- the lower flat edge of the external peripheral wall can be extended by a gripping visor (17).
- a safe opening system with regard to children, with a view to making it difficult or even impossible for them to open the cap-cover, can be installed in line with the visor (17).
- This device is a flexible blade (23) forming an integral part of the mounting means and being in the form of a protrusion establishing a vacuum between it and the mounting means.
- This flexible blade is placed below the visor by following its profile in such a way that the protrusion of the visor making it possible to exert a vertical thrust to assume its opening is faired by this flexible blade in the absence of stress. Therefore access to the visor can only be done after having exerted pressure on this blade in order to cause deformation and free access to said visor.
- the protection of the child is ensured by the necessary realization of two complementary gestures, and to be exercised simultaneously, the first gesture being a horizontal pressure on the flexible blade, the second being a vertical pushing action from bottom to high on the exposed visor, thanks to the maintenance of pressure on the flexible blade.
- the mounting means (2) of the cover cap (1) is formed by a fixing ring (2) which is mounted on the tubular casing of the access port to the container to be closed, this ring: - having a dimensioning adapted to that of the tubular casing, - being provided on its internal face, intended to be in contact with the external surface of the casing with a means of * snap-in relief (18), with respect to of the external face of the envelope, on which the means allowing the latching of the ring is opposite, that is to say hollow.
- a fixing ring (2) which is mounted on the tubular casing of the access port to the container to be closed, this ring: - having a dimensioning adapted to that of the tubular casing, - being provided on its internal face, intended to be in contact with the external surface of the casing with a means of * snap-in relief (18), with respect to of the external face of the envelope, on which the means allowing the latching of the ring is opposite, that is to say hollow.
- the external peripheral surface of the tubular casing (24) of the orifice (4) for access to the container to be closed comprises two projecting peripheral flanges (26) and ( 27), separated from each other by creating a groove (25), having in section a substantially rectangular shape, so that: • the thickness of the tubular envelope inside the groove n ' is not modified, and that • the fixing ring (2) is forced to be mounted in said groove (25).
- a peripheral groove (25) which can have in section a substantially rectangular, hemispherical or hemielliptic shape, is made hollow in the thickness of the wall of the tubular envelope (25) of the container so that: • the thickness of the tubular envelope inside the groove is modified, and is less than that of the tubular envelope and that • the fixing ring (2) comes to be forced into said groove (25).
- the relatively rigid hinge-type connecting means (3) is present between the sealing means (1) and the mounting means (2) on the tubular casing of the access opening to the container (4).
- This hinge-type connecting means (3) is formed by two film hinges (6) and (7) spaced from each other, and giving rigidity to the connection between the plug. - cover (1) and the fixing ring (2).
- Each film hinge (6) and (7) is formed of two parts linked together by a polymer film playing the role of an axis of rotation (19) and (20) allowing the cycles opening / closing of the shutter means, one of the parts being integrated into the shutter means (1), the other part being integrated into the mounting means (2).
- each of the two hinges (6) and (7) integrated into the shutter means (1) and into the mounting means (2) constitute brackets for fixing the two film hinges to the shutter means and the mounting means.
- the tamper-evident means (8) or even tamper-evident witness is formed of micro-links connecting the lower peripheral surface of the cap-cover (1) to the upper peripheral surface of the fixing ring (2), these micro- links being micro-points of connection, independent of each other, forming a peripheral ring gear of connection between the desiccant sealing means and the means of mounting on the tubular envelope of the container orifice, - crown which is broken during the first opening ⁇ -by lifting the cover cap by means of the visor (17).
- the mechanical spring effect means (9) for assisting with the opening or closing of the desiccant closure means (1) is placed in the space between the two film hinges (6) and (7) and looks like a square.
- This mechanical means (9) with spring effect also controls the amplitude of the opening angle of the shutter means (1) which is in this case at 120 °, so that, from its position of limit switch at 120 °, the closure means is easily driven in the closing direction by a finger of the hand holding the container provided with the closure device.
- the mechanical spring-effect means (9) is simultaneously linked to the cap-cover (1) by a film hinge (21) and to the fixing ring (2) of the device according to the invention by another film hinge (22 ).
