Definitions
- the invention relates to a safety closure device for a container whose mouthpiece is provided with an external screw thread, a device that is child-proof and also includes a first-opening indicator and an element desiccant.
- the invention more particularly relates to a safety device for screw-fastening for a container, comprising a single cap to be screwed onto said container, said cap having the capacity to disengage from a locking position via a double lateral pressure.
- said device being further equipped with a first-opening indicator ring cooperating with the neck of the container on which the closure device is mounted and with a desiccant element.
- Closing devices offering child safety can be of different types.
- the security can be either the consequence of a deformation by opposite lateral pressure of the plug allowing unblocking of the unscrewing function, followed by the rotation of the plug, or a vertical displacement engaging a device allowing the unscrewing, this vertical movement in front of be driven simultaneously with a rotation.
- Child-resistant caps operating on the principle of a double vertical movement and rotation equipped with a first-opening indicator ring exist, but are relatively complex to implement in that they involve the presence and a plug internal screw on said container and a coaxial outer cap integrally covering the inner cap, the outer cap having capacity to drive the inner cap by means of a locking system 1, when are formed, on the outer cap, axial pressure and rotation.
- the document WO9850283 discloses a child-resistant screw stopper of the simple plug type, operating in the mode of a double opposite radial pressure and a rotation allowing unscrewing, said stopper being equipped with a first opening control ring.
- the cap comprises, on its lower outer periphery, that is to say, its skirt, two diametrically opposite zones on which can be exerted lateral pressures.
- Child safety notches presenting as protuberances, towards the inside of the stopper, allow the locking in rotation of the stopper. These notches are positioned at 90 ° of the pressure zones and extend downwardly to the lower level of the cap skirt.
- First and second child safety notches are placed on the neck of the specific container to which the stopper is associated, and are positioned above the first-opening indicator ring.
- the connection between the first opening control ring and the lower part of the plug is ensured by breakable bridges positioned at 45 ° with respect to the pressure zones. It is important to overcome the child safety before the first opening indicator ring can not be detached by rupture of the breakable bridges, rupture obtained by rotational rotation of said ring during the rotation of the cap at the time of unscrewing.
- the first opening indicator ring is removed after opening.
- U.S. 4,452,363 discloses a container equipped with a child-resistant screw cap with a first-opening indicator ring, the child lock being achieved through diametrically opposite side pressures exerted on the lower portion of the cap skirt.
- the skirt is of conical shape and comprises a system of notches and notches which make it possible to secure and detach the first opening control ring.
- Document US Pat. No. 5,836,465 describes a container equipped with a child-resistant screw cap with a first-opening indicator ring.
- the neck of the container has a screw thread and two first locking notches below the thread, and diametrically opposed.
- the cap is made from material allowing the skirt of the cap to be deformed under the effect of a lateral pressure.
- the inner part of the plug has two second locking notches positioned opposite diametrically on the inner lower portion of the deformable skirt.
- the first and second locking notches have the ability to engage the in each other when the cap is completely screwed into the neck of the container and thus prevent any rotation of the plug relative to the neck of the container except if there is deformation of said cap, then releasing the locking system.
- the thread is multi-pitch, disengaging by a simple rotation to 180 °, or less, the cap, the collar of the associated container.
- Such plugs have no features to ensure the controlled dehydration of the container with which they are associated, forcing then the use of separate means of dehydration, to be used in applications such as, for example, the packaging and storage of moisture-sensitive products, such as in particular drugs.
- a first object of the invention is to provide a safety closure device of a container by screwing, to the test of a child on unscrewing, this device , consisting of a single cap, and not, for reasons of simplicity and cost reduction, two nested plugs, functioning by deformation of the skirt of said cap, thus unlocking a means during the application of radial pressures exerted in opposition on two diametrically opposite zones of the deformable skirt of said plug of the device, followed by a rotation allowing unscrewing.
- Another object of the invention is to provide a security closure device for a container by screwing, to the childproof unscrewing, comprising an integrated dehydrating means in said closure means and an indicator of inviolability f of the first opening control ring type.
- Another object of the invention is to provide a device for closing a container by screwing, to the test of a child on unscrewing having a desiccant means integrated in said closure means and a means of testimony of a first opening cooperating with the neck of the container on which the closure device is screwed.
- the invention therefore relates to a child - resistant closure device for a screw container, consisting of:
- a plug allowing it to be screwed onto the neck of a container with which it is associated, said stopper consisting of a bottom and a cylindrical side wall, having on its internal face, a step of screw and a first set of notches, called child safety, and
- a first opening control ring connected to a cylindrical side wall by bridges scored, said ring being also equipped on its internal face, a second set of notches, called inviolability, the first set and the second set of notches cooperating with sets of corresponding notches positioned on the base of the neck of the container , and characterized in that the cylindrical side wall of the plug is formed of two zones, a first rigid and non-deformable high zone, of diameter d1, forming a body of the plug, comprising the thread, and a second low zone of diameter d2, forming a flexible and deformable skirt under a double centripetal symmetrical lateral pressure.
- the closure device of a screw container consists of a screw cap allowing it to be screwed onto the neck of a container with which it is associated, said stopper being composed of a bottom and a cylindrical side wall, having internally in the portion associated with the bottom, a thread and in the open portion, on its inner face, a first set of notches, called child safety and a ring first opening indicator, connected to the skirt by breakable bridges, said ring is also equipped on its inner face, a second set of notches, called inviolability, the first set and the second set of notches cooperating with corresponding notches positioned on the base of the container neck.
- the cap also has in its bottom a housing for storing a composition or an element desiccant, said housing being inserted freely into the neck of the storyteller.
- the screw thread closure device comprising a stopper and a first opening control ring is intended for a container of the type, for example a blown injected bottle, comprising a collar that is preferably several threads and with a rapid pitch, intended to receive products sensitive to the moisture and must therefore be kept in a dehydrated state.
- the cap comprises a cylindrical side wall formed of two zones, a first rigid and non-deformable high zone, of diameter d1, forming a body of the plug, comprising the thread, a second low zone of diameter d2, forming soft and deformable skirt, under a double lateral symmetrical pressure centripetal, the high and low zones being interconnected by a rigid shoulder.
- the diameter d1 is smaller than the diameter d2.
- the flexible cylindrical skirt comprises two diametrically opposed gripping surfaces located at the lower periphery of said skirt, and to precisely position the r force exerted by the thumb and forefinger of the user of the device during the release of the child safety before unscrewing and opening said device.
- This skirt is made of a material such that said skirt may be deformed, in particular ovalized, in an elastic manner, when a force is exerted on the two gripping zones and that this skirt covers its initial shape when this effort ceases.
- Body and skirt cap are monoblock and therefore made from the same material.
- the wall thickness of the skirt is such as to enable its easy deformation when pressure is exerted on the two gripping surfaces.
- the wall thickness of the body comprising the thread is such that the rigidity is enhanced.
- the outer surface of the cap body is architected so that a succession of concave shapes, facilitating the grip of the cap, also reinforces the rigidity of said body.
- the skirt of the cap comprises, on its inner face, a first set of two notches, called child safety, respectively positioned on the internal face of the skirt of the cap, diametrically opposite one another, according to a diameter itself parallel to the plane of orientation of the two gripping surfaces and whose function is to prevent rotation of the plug when the skirt is not deformed during an attempt to unscrew the device, cooperating with two corresponding notches arranged on the collar of the associated container.
- the two notches of the first set of notches present on the inner surface of the cap skirt are of a height such that they cooperate with the two corresponding notches located on the neck of the associated container.
- the diametrical plane passing through the steep faces of the two opposite notches of the first set of notches positioned inside the skirt of the plug is perpendicular to the diametral plane coinciding with the plane of symmetry bisecting gripping surfaces located on the lower part. the skirt of the cap.
- the cap thus remains locked in rotation when said skirt is in its undeformed state, that is to say not ovalized.
- the freedom of rotation of the plug is found, when said skirt is placed in an ovalized state, thus causing the breaking of the breakable bridges by rotation of the plug to the extent that the control ring of first opening is not able to follow this rotation .
- This movement causes the uncoupling of the control ring of first opening relative to the plug.
- the notches of the first set of notches said child safety are positioned in a plane perpendicular to the two gripping surfaces.
- the axial plane consisting of the steep faces of the two diametrically opposite notches of the first set of notches is perpendicular to the axial plane formed by the steep faces of the two notches of the second set of notches said inviolability constituting the locking means of the control ring of first opening, located in the axial plane of symmetry of the gripping areas.
- the two notches of the first set of so-called child safety notches are evenly distributed, also for reasons of force balancing during the unscrewing of the child-resistant closure device and for; reasons for ease of mold design.
- the profile of the notches of the first set of notches present on the inner part of the skirt of the cap and on the outside of the neck of the associated container is such that it allows the screwing of the cap and this, thanks to a profile with soft ramp, causing a slight deformation of the cap skirt but does not allow its unscrewing, by a steep profile that prevents any rotation of said undistorted skirt during unscrewing of the closure device.
- the height of the two notches positioned on the neck of the container, cooperating with the two notches of the first set of notches, is such that said notches are positioned downwardly within the area of the thread on the neck of the container, and extend to the level of the peripheral lower zone of the first opening control ring, when it is in place, all other notches having a lower height.
- Such a height makes it possible, if it were necessary, to also block the two notches in the second set of notches present inside the first opening control ring, if they managed to pass over the two corresponding dedicated notches of the container neck, with which they cooperate.
- the difference in diameter between dl and d2 allows an optimized contact surface and homogeneous over the entire height of the notches and enhances child safety.
- two additional tamper evident notches positioned on the inside of the ring are provided to cooperate with the lower part of corresponding notches positioned on the neck of the container. They are therefore positioned in a plane perpendicular to the first set of tamper-evident notches.
- the cap of the child-resistant closure device comprises a tamper-proof ring of first opening, made integral, by means of breakable bridges, of the skirt of the cap, said bridges being positioned on the lower annular periphery. the skirt of the cap.
- the first-opening indicator ring has, on its inner surface, a second set of two notches, called tamper-proof, whose function is to prevent its rotation, during the unscrewing of the device, cooperating with the two corresponding notches arranged on the neck of the associated container, and this, in order to cause breaking shear bridges.
- the two notches of the second set of notches present on the inner surface of said ring, when integral with the plug, are of a height such that they cooperate with the two corresponding notches present on the neck of the container.
- the lower circumference of the skirt of the cap is sheared during the first opening and thus allows to materialize the inviolability.
- the two notches of the second set of notches are regularly distributed over the circumference of the ring and on the neck of the container with regard to their correspondents with whom they cooperate.
- the two notches of the second set of notches said inviolability are positioned to the right of the two gripping surfaces.
- the diametral plane passing through the two steep faces of the two notches of the second set of notches, positioned inside the first opening control ring is in the diametral plane of symmetry of the two diametrically opposite gripping zones, positioned on the outer surface of the skirt of the cap.
- This engagement of the notches of the second set of notches is reinforced by the fact of the pressure exerted on the two diametrically opposite gripping zones, and positioned at the right of these two notches of the second set of notches cooperating with corresponding notches positioned on the neck of the container.
- the presence of a set of two tamper-evident notches positioned on either side of the gripping zones is intended to ensure that the tamper-evident notches are engaged with the corresponding notches of the neck of the container, the deformation of the outer skirt being mainly transmitted to the tamper-proof ring by the tamper-proof bridges.
- the first opening control ring is connected to the skirt by breakable bridges, so that the deformation of the skirt does not cause an equivalent deformation of the ring.
- the breakable bridges are preferably four in number, distributed in proximity and on either side of each notch of the second set of notches located on the inner face of the ring.
- the bridges, taken in pairs, are located near and on either side of the notches of the second set of notches called inviolability.
- This arrangement makes it possible to transmit the deformation of the gripping zones to the first opening control ring, during the ovalization caused by the skirt, and therefore to better lock the ring in its rotation, thus making the bridges easier to break.
- the two notches of the second set of notches are distributed at 180 ° on the circumference of the neck of the container and on the circumference of the control ring of first opening, the diametral plane defining the abrupt face of these notches being perpendicular to the diametral plane defining the face steep two notches of the first set of notches.
- This regular circumferential distribution allows a balancing of effort during the unscrewing of the child-resistant closure device. Such a regular distribution is also so for reasons of ease of mold design.
- the profile of the notches of the second set of notches present on the inner part of the first opening control box and on the outside of the neck of the associated container is such that it allows the screwing of the plug and the positioning of the connected ring and this , thanks to a profile with a soft ramp, causing a deformation of the tamper evident ring of first opening, but does not allow its unscrewing without breaking of the bridges connecting the control ring of first opening to the lower part of the skirt of the cap, by a steep profile which prevents any rotation of said ring during unscrewing of the closure device.
- the profiles of the notches of the first and second set of notches when observed according to a sectional plane perpendicular to the axis of rotation, comprise a gentle ramp, followed by a steep slope, the profiles of notches with which they cooperate being arranged in an antagonistic manner, so that, for two cooperating notches, the soft slopes slide on one another during the closing and the steep slopes block at the opening.
- the notches of the second set of notches arranged on the neck of the container are located below the notches of the first set of notches ensuring the child safety function. They are of a height less than that of the notches of the first set of notches and correspond substantially to the height of the first opening control ring.
- the gripping surfaces are defined on the flexible portion of the skirt of the plug to materialize the points of application of the forces.
- the first opening control ring is connected to the outer skirt of the cap by two sets of two bridges sececable, each breakable bridge being located on either side of the two gripping surfaces.
- first opening control ring connected to the skirt by the two sets of breakable bridges deforms in the same manner as the skirt in the gripping surfaces but does not undergo a deformation equivalent to that of the skirt in the perpendicular plane, because not connected in these areas to the skirt by bridges.
- the f seal between the inside of the container neck and the screw cap is provided by means of a cylindrical element coaxial and concentric with the plug positioned within the cap resting on the bottom said plug.
- This cylindrical element adjusts, via a terminal chamfer, in the neck of the container in that its diameter external is adjusted to the inner diameter of the neck of the container and that it is of a certain height.
- the closure of the child-resistant closure device further comprises a desiccant means of attached type, the desiccant being placed in a suitable housing, located on the bottom of the inner cap, said housing being closed by a sealing means which is not impervious to ambient humidity, for example a porous cardboard membrane, to ensure rapid drying of moisture sensitive products and packaged in the container.
- a sealing means which is not impervious to ambient humidity, for example a porous cardboard membrane, to ensure rapid drying of moisture sensitive products and packaged in the container.
- the housing is thus concentric and concentric with the plug, and is inserted freely into the neck of the container.
- the desiccant used in the container is selected from the group consisting of silica gels, molecular sieves, diatoms or other desiccants, in powder form or deposited on a powdery carrier. They can also be in the form of mixtures
- the desiccant may also be a capsule contained in said housing and made of a desiccant polymer material containing or not desiccant fillers or more generally of any material containing a desiccant.
- the plug of the device according to the invention is produced by injection molding from thermoplastic polymers, preferably chosen from the group consisting of polyethylenes, polypropylenes, copoly ⁇ nomme d 1 ethylene / propylene copolymers used alone or in mixture, formulated or unformulated.
