Description

Shutter and dispensing device

  The present invention relates to a device for sealing and or dispensing. It finds more particularly its use in the field of tanks with pourer cap, and especially those provided with a pouring cap with spring hinge. This type of plug allows, in the closed position, to close an opening of a tank on which it is mounted, while in the open position, it allows a distribution of the product contained in the tank through a port of distribution that is in fluid communication with the contents of the reservoir. The spring hinge makes it easy to switch from the closed position to the open position.

  Pour caps are widely described in the state of the art, they generally comprise a body adapted to be mounted on the tank, in particular around a neck defining an opening of said tank, and secondly a lid connected to the body at the way of a hinge. The body has a dispensing orifice which is closed by the lid when the cap is in the closed position. In the open position, the cover at least partially disengages said dispensing orifice to allow the product to exit the reservoir.

  Generally to move from the closed position to the open position, it is necessary to hold the tank in one hand, while the other hand pushes on a protruding part of the lid. Preferably, this protruding portion is defined on a side diametrically opposite the hinge.

  In the case where the hinge is spring effect, simply lifting the cover relative to the body causes the subsequent opening movement. The spring hinge brings the lid into the open position, provided that it is brought to an unstable equilibrium position, and then very slightly influencing the output of this unstable position to the open position.

  Such pourer plugs are in particular known from US-4,813,560 and US-3,741,447.

  In a variant, other pouring plugs are known from teaching documents US Pat. No. 4,124,151 and US Pat. No. 4,911,337 for which the spring hinge is in particular obtained after engagement of a ball of the cover in a boss of the body. The ball engaged in the boss forms the axis of the hinge around which the lid can rotate relative to the body. The spring effect is obtained from an elastic portion connecting a border of the lid to a body edge. This resilient portion extends the dummy lid extending from one side of the hinge opposite to that of which the lid is defined. In this case also, to obtain the passage from the closed position to the open position of the cover, a thrust must be exerted on a protruding portion of the cover, said protruding portion being diametrically opposite to the elastic portion.

  Document FR-1,161,611 is known from the teaching of another type of pouring plug for which the lid also comprises a protruding part and a hinge provided with a spring means. In this case, the protruding portion is defined on one side of the hinge opposite to that in which the lid is defined. To obtain a clearance of the dispensing orifice, pressure is exerted on the outer periphery of this protruding part so as to create a lever arm.

  In the embodiment taught by this document FR-1,161,611, the cover is able to return elastically in the closed position, but it has a major disadvantage in that the open position is obtained only as long as a constraint is exerted on said protruding portion. The spring means exerts a permanent constraint to return the lid to the closed position. This spring means does not know a reversible unstable equilibrium position allowing it to move from a first stable position, for example closed, to a second stable position, for example open. Indeed, it is included in the thickness of the lid, and stiffens it. The partial opening provided by the lid is also dependent on the plastic properties of the lid within which the spring means is disposed.

  The handling of a tank with a plug according to FR-1,161,611 is not easy. Indeed, even if it allows to hold and open the tank with one hand, when pouring the product so as to orient the dispensing orifice down, at least one finger of the hand to maintain With the lid open, the hand is then forced into a twisted position. Moreover in this position, the hand that grips the tank can not properly adjust the inclination given to the tank given the complex position in which it is constrained.

  The pouring plugs known in the state of the art are problematic. Indeed, those that can be kept in the open position when distributing the product all require the use of both hands to ensure the opening or closing of said pourers. And even pourable caps that can be opened and held with one hand is problematic to the extent that the opening is only possible by maintaining a constraint on part of the lid.

  There is a need for new pour plugs, including pour plugs whose lid is of minimal bulk whether in the open or closed position.

  The object of the invention is to solve all or part of the problems mentioned above. For this purpose, the pouring cap according to the invention, when mounted on a container, can be moved from the open position to the closed position and vice versa, by means of the same hand holding the container. Furthermore, the opening, like the closure, are obtained by exerting a simple pressure on an upper bearing surface of the lid of the pouring cap. The lid is in the invention rotatably mounted relative to a plug body, about a hinge axis. On either side of the hinge axis, the cover has a bearing surface, the first bearing surface serving to cause the opening, and the second closing. Furthermore, the hinge is preferably spring-loaded to facilitate the end of the opening or closing movements.

  The subject of the invention is a closure and / or dispensing device intended to equip a reservoir, the device comprising: i) a body adapted to be mounted on the reservoir, and having a dispensing orifice in communication with an opening delimited by the reservoir, and ii) a cover adapted to selectively close said dispensing orifice, said cover being articulated relative to the body about an axis of a hinge, and being able, in the absence of any external stress, to remain in position. open position, and iii) at least one elastically deformable strip connecting the cover to the body, characterized in that the cover has two ends along an axis perpendicular to the axis, the latter being located relative to said ends so that the opening of the lid may result from a pressure exerted on a portion of the lid located between the axis and the end of the lid opposite that at which the lid opens.

  The subject of the invention is also a device for closing and / or dispensing able to be mounted at an opening of a reservoir, the device comprising i) a body able to be mounted around said opening, this body having a dispensing orifice in fluid communication with the reservoir, and ii) a hinged lid relative to the body via a spring hinge, the lid having two portions on either side of an axis of the hinge a first portion of the lid having means for closing the dispensing orifice in the closed position, and - a second portion of the lid forming a bearing surface to allow driving of the lid from the closed position to an open position, - to at least one elastically deformable strip connecting the lid to the body, characterized in that the second portion of the lid is at least partly received in a cavity of the body when e the lid is in the open position.

  A hinge is generally composed of two parts joined by a common axis around which at least one of the parts can rotate. When a hinge is defined by a film of thin thickness connecting the two parts, then the axis around which the parts can rotate corresponds to an elongated area of smaller thickness of the film. According to a preferred embodiment, the hinge is of the hinge-film type.

  By "spring-action articulation" is meant a hinge comprising an elastic connecting strip configured so as to be subjected to a maximum elastic stress (either in extension or in compression) in an intermediate position between the open position and the position closure. The elastic band also connects the two pieces. It is attached to each of the parts so that the distance between said two points of attachment is variable when moving from the open position to the closed position. The band has a clean elasticity, and may have an unstable equilibrium position between the two open and closed positions.

  For example, the elastic band has a length such that there exists between the two open and closed positions, a position in which the stress in extension or in compression is maximum, which induces the instability of this intermediate position between the open position. and the closed position.

  Advantageously, the lid forms a lever, so that a force exerted on one of the two portions of the lid causes the two portions to pivot about the axis of the hinge.

  Lever means a unitary body here formed by the cover, the lever being movable about an axis, in this case around the axis of the hinge. And by lever arm means a distance between a point of application of a force and a rotational hinge axis.

  Preferably, in the closed position, the spring hinge is hidden by the cover, in particular between the cover and the body. The lid being divisible into two portions because of this hinge, each of the two portions then participates in hiding the hinge.

  According to a particular embodiment, the spring hinge comprises a first portion integral with the body, a second portion secured to the lid and said elastic band to connect these two parts.

  Especially in the case where the hinge is hidden under the lid in the closed position, then the first part may be more particularly attached to a rim of the cavity formed in the body, and the second part may be connected to a lower surface of the lid. In this case, the elastic band is also hidden by the lid in the closed position. Preferably, the second portion is connected to the lower surface of the second portion of the lid, which results in particular the entry at least part of this second portion into the cavity.

  The advantage of having the hidden hinge under the cover, in the closed position, is to protect this hinge from any soiling or any impact especially during the storage of this type of device.

  Advantageously, this second part is connected at a distance from the ends of the upper surface of the lid, and the first part is attached to an area of the rim of the cavity as close as possible to the dispensing orifice. In this case the hinge advantageously extends along a line separating on one side the dispensing orifice and on the other an access to the cavity.

  Preferably, an axis of the hinge is adapted to tolerate elastic deformation during the transition from the closed position to the open position, in particular under the effect of a pressure exerted on the bearing surface. This elastic deformation leads to a translation of the second part relative to the first part. In the particular case where the hinge is of the film hinge type, the zone forming the axis of the hinge deforms elastically to be slightly lower than at rest.

  Alternatively, and or additionally, under the effect of the pressure exerted on the bearing surface, an upper surface of the lid may also be adapted to crash resiliently toward a seat of the body.

  In these two cases, and according to an advantageous aspect of the invention, insofar as a lower surface of the cover comprises a crutch, this crutch then bears on the body and is able to form locally at the seat a new axis of rotation, or temporary hinge axis, when moving from the closed position to the open position.

  This temporary hinge axis is formed only during the period of time when pressure is exerted on the bearing surface, and as long as the axis of the hinge is able to sink during said passage from the closed position to the open position. The interest of this crutch is that it allows to temporarily change the value of different arms of leverage.

  Preferably, the temporary hinge axis is formed between the dispensing orifice and the axis of the hinge. Thus, with a normal pressure force exerted on the bearing surface of the second portion, a larger force can initially be obtained at the first portion closing the dispensing orifice. This arrangement is particularly advantageous when it is necessary to disengage a pivot of the lower surface of the first portion of the cover of said dispensing orifice.

  According to another advantageous aspect of the invention, the spring hinge is in a stable position in the open and closed positions, and passes through an unstable equilibrium position between these two positions.

  Advantageously always, in the open position, an angle defined between the body and the cover is greater than 90, and is preferably less than 130.

  According to an advantageous aspect of the invention, the passage from the closed position to the open position can be caused by a pressure exerted on the bearing surface. In particular, the pressure can be exerted according to at least one component orthogonal to this bearing surface.

  For example, the second portion may have a length, along an axis orthogonal to the axis of the hinge, less than a length of the first portion relative to the same axis.

  Advantageously, a lower face of the first portion may comprise a pin adapted to engage sealingly in the outlet orifice.

  According to another advantageous aspect of the invention, the device comprises a locking means for preventing the passage from the closed position to the open position, this locking means cooperating with a rim of the cavity so as to prevent rotation of the second portion relative to the axis of the hinge. This locking means increases in particular the length of the lid along an axis orthogonal to the axis of the hinge, so that at rest, in the closed position, the locking means bears on this flange.

  The position of the locking means is maintained under the effect of an elastic tongue which maintains it in said rest position. To allow the passage from the closed position to the open position, it is first necessary to exert pressure on the locking means, to constrain said elastic tongue. When the tab is constrained, the locking means is preferably axially displaced along an axis orthogonal to the hinge. At the same time as this pressure is exerted in a component at least parallel to the bearing surface, preferably the user exerts a stress in a component at least orthogonal to the bearing surface of the lid, to finally cause the opening.

  Alternatively, the elastic tongue can also be constrained in its locking position, in this case the locking means abuts against an inner periphery of the rim of the cavity.

  Preferably, a pressure exerted on an outer periphery of the locking means, in at least one component parallel to the bearing surface allows compression of the elastic tongue, and thus allows a passage from the closed position to the open position.

  Advantageously, the device is preferably made in one piece by molding thermoplastic material, preferably selected from the family of polyolefins. For example, the device is molded of polypropylene.

  The subject of the invention is also a tank provided with a closure and / or dispensing device according to the invention.

  The invention will be better understood on reading the description which follows and on examining the figures which accompany it. These are presented only as an indication and in no way limitative of the invention. The figures show: FIG. 1a: a profile view of a tank provided with a device according to the invention in the closed position; - Figure 1b: a profile view of a tank with a device according to the invention in the open position; - Figure 2a: a longitudinal sectional view of the device according to the invention in the closed position; - Figures 2b and 2c: a longitudinal sectional view of the device according to the invention in the open position and in the open position; - Figure 2d: a longitudinal sectional view of the device according to the invention in the molding position; - Figure 3: a side view of an alternative embodiment of the device according to the invention in the closed position; - Figure 4: a longitudinal sectional view of the device according to Figure 3; - Figures 5a, 5b and 5c: a side view of different embodiment of a locking means adapted to be mounted on a device according to the invention; - Figures 6a and 6b: a longitudinal sectional view of the device according to the invention in the unlocked position and in the open position.

  FIG. 1a shows a closure device 1 mounted on a reservoir 2. The reservoir 2 is, for example, of elongate shape along an axis X. It comprises an opening, not visible in FIG. 1a, preferably defined orthogonally to this axis X. The device 1 mainly comprises a body 3 mounted on the reservoir 2, and a cover 4. The body 3 is preferably mounted permanently on the reservoir 2, for example by cooperation between a relief of an inner periphery of the body 3 and a complementary relief of an outer periphery of the tank 2.

  The cover 4 is movable relative to the body 3, as shown in Figure lb, where the cover 4 is in the open position, while in Figure la the cover 4 is in the closed position. In the open position, a dispensing orifice 5 of the body is now visible and makes possible the dispensing of the product contained in the reservoir 2. Indeed, the body 3 is mounted on the reservoir 2 so that the dispensing orifice 5 is in fluid communication with the opening of the reservoir 2, this opening being always masked by the body 3.

  Preferably, this dispensing orifice 5 is defined at a seat 6 of the body 3, the seat 6 defining a surface substantially orthogonal to the axis X. The cover 4 is articulated around a hinge 7 of axis 8 , the axis 8 of this hinge 7 being defined parallel to the surface of the seat 6, and orthogonal to the axis X. In the open position, the cover 4 defines an angle with the surface of the seat 6 greater than 90, and the order of 130. The seat 6 has a cavity 9 inside which at least a portion of the lid 4 is disposed when in the open position.

  Indeed, the axis 8 of the hinge 7 being defined at a distance from the edges of the lid 4, it can be defined by two portions each disposed on either side of the axis 8. For example a first portion 10 extends in the closed position above the dispensing orifice 5, while a second portion 11 serves as a rocker or bearing surface for including driving the first portion 10 of the closed position to the open position. Said second portion 11 corresponds to the part of the lid 4 which tilts inside the cavity 9 in the open position.

  According to FIG. 2a, the reservoir 2 preferably comprises a neck 12 at which the opening 13 of the reservoir 2 is defined. The collar 12 forms a local restriction of an outside diameter of the receptacle 2. The body 3 is preferably mounted , here in force, on a part of the tank 2 wider than the diameter of the neck 12. Moreover, to be retained on the tank 2, the body 3 comprises a chimney 14 in communication with the dispensing orifice 5, this chimney 14 being fitted inside the neck 12. Thus fluid communication is provided between the reservoir 2 and the dispensing orifice 5. The chimney 14 is sealingly mounted in the neck 12 to prevent leakage when the device is presented. "upside down", ie, the dispensing orifice 5 facing the ground.

  According to the embodiment shown in Figure 2a, the cover 4 comprises a pin 15 adapted to cooperate with the dispensing orifice 5 so as to seal it tightly. Preferably, the orifice 5 is of circular section and the pin has a cylindrical complementary shape. The pin 15 sinks at a low height inside the orifice 5. In fact, since the lid is rotatably provided around the hinge 7, by describing such a rotary movement, the pin 15 must be able to easily exit from this hole. orifice 5, while providing good sealing conditions in the closed position.

  The hinge 7 is preferably disposed at a lower surface 19 opposite the upper surface 16 of the lid 4. Thus it is protected when the device is in the closed position. The hinge 7 is here of the film hinge type, it comprises a first portion 17 secured to the seat 6, and a second portion 18 integral with the cover 4. The axis 8 of the hinge 7 is formed by a plastic film between the first part 17 and the second part 18. Indeed, the hinge 7 is preferably obtained by molding plastic material.

  In particular the second part 18 is attached to the lower surface 19 of the cover 4, and more particularly to a zone of this lower surface 19 disposed at the second portion 11. Thus, when the cover 4 is driven in the open position, the second portion 18 is rotated relative to the first portion 17.

  The pin 15 is in particular defined at the bottom surface 19, on one side of the lid 4 opposite the zone with which the second portion 18 is attached.

  The first portion 17 is preferably attached to an area 21 of the seat 6 defined at a rim 20 of the cavity 9, the zone 21 of this rim 20 being further defined by an outer periphery of the chimney 14 emerging out of the Col 12.

  In the example shown, the hinge 7 is spring-loaded, it comprises for this purpose an elastic band 22, connecting on the one hand the first part 17 and second part the second part 18. In Figure 2b, the band elastic 22 is in a position of maximum extension, corresponding to an unstable equilibrium position. Indeed, the distance 23 between the two points of attachment of the elastic band 22 on the two parts 17 and 18 respectively, is, in this position, slightly greater than the rest length of this elastic band 22.

  The band 22 is attached to the two parts 17 and 18 so that the unstable position is provided between the fully closed position, Figure 2a and fully open Figure 2c. This open position is partly defined by a stop of a border 24 of the cover 4 against the outer periphery of the chimney 14 emerging out of the neck 12, or the outer periphery of the neck 12 itself. This outer circumference of the chimney 14 or the outer periphery of the neck 12 participate in the definition of the inner periphery of the cavity 9.

  In this open position, the elastic band 22 is in a stable position, and does not tend to return of itself in the unstable position of Figure 2b. Whatever the movements involved in the tank 2 on which the device 1 is mounted, the lid 4 remains in the open position, and never interferes with the dispensing of product through the orifice 5. In addition, because the portion 1, serving as a bearing surface for driving the lid 4 in the open position, is disposed inside the cavity 9, the user can grasp the tank 2 over its entire height, or even at the outer periphery of the body 3, without risk of applying pressure on the upper surface 16, and thus to close the lid 4.

  The cover 4 comprises, in particular at the level of the upper surface 16, two opposite ends 24a and 24b along an axis orthogonal to the axis 8, a first end 24a delimiting in part the first portion 10 and a second end 24b partially delimiting the second portion 11.

  Preferably, the device 1 is molded in one piece in a thermoplastic material. Figure 2d shows the device 1 in the position in which it is molded. The peculiarity of this mold lies in the presence of a second film hinge 25 between the second part 18 and the cover 4, this second film hinge 25 tolerating a movement of the cover 4 relative to this second part 18. This movement then allows the assembly cover 4 relative to this second portion 18 so as to make them integral. Indeed, they are not provided integral since the assembly to facilitate the molding and the joint plane of such a room. This film hinge 25 is in particular provided at the second end 24b.

  To make the cover 4 functional and make it integral with the second part 18, this lid 4 is folded onto the second part 18 so as to engage, preferably irreversibly, a pinion 26 in a complementary orifice 27. In the example the pinion 26 is provided on the lower surface 19 (here presented upwards, before mounting), and the complementary orifice 27 is provided in the second part 18. The pinion 26-complementary orifice assembly 27 forms a securing means of the first part 18 to the lid 4.

  Alternatively, in the example shown in Figures 3 and 4, a device 1 as described above does not necessarily include a pinion such as 26 and a complementary orifice such as 27. An external locking means 28 is then mounted on the cover 4 so as to make it integral with the second part 18. This external locking means 28 is a means for securing the second portion 28 to the cover 4. This external locking means 28 has a form of clamp. A part

  upper 29 of the clamp 28 comes into contact with the upper surface 16 of the cover 4, while a lower portion 30 of the clamp 28 comes to cooperate with a complementary relief 31 presented by the second part 18 of the hinge 7.

  This locking means 28 also provides a locking function of the closed position. Indeed, the locking means comprises at least one resilient tongue 32 which bears against the second end 24b of the cover 4 so as to push the locking means 28 away from the second end 24b. The elastic tongue 32 extends across the hollow formed by the clamp, and in particular the hollow formed between the upper part 29 and the lower part 30.

  Even if the elastic tongue 32 tends to push the locking means 28, the latter remains nevertheless integral with the cover 4, and its stroke in this direction is limited by the cooperation between the complementary relief 31 and the lower portion 30. Preferably, the tongue 32 is arranged such that when the means 28 is mounted on the cover 4, the tongue 32 forms an extension 33 of the second end 24b of the cover 4. This extension 33 is then opposite the rim 20 of the cavity 9. In this rest position, the means 28 thus prevents a depression of the cover 4 in said cavity 9. The extension 33 corresponds, in the embodiments shown, to the junction point between the upper and lower portions respectively 29 and 30 .

  To allow the opening of the cover 4, it is first necessary to defuse the locking means 28. For this purpose, it is necessary to exert a force to constrain the elastic tongue 32 until no more part means 28 is vis-à-vis the rim 20, and therefore the rotation of the lid 4 around the hinge 7, towards the interior of the cavity 9, is no longer prevented.

  For example, the outer surface of the upper portion 29 has grooves to facilitate handling and the exercise of a point pressure.

  According to the various embodiments of the locking means 28, shown in Figures 5a, 5b and 5c, in each of these variants, the upper portion 29 forms a continuous surface to the zone forming the extension 33. The lower portion 30 is materialized by a transverse beam connecting two lateral sides 34 and 35, these two sides 34 and 35 connecting on either side the upper part 29 to the lower part 30.

  According to a first variant, FIG. 5a, a tongue 32a extends transversely between the upper 29 and lower 30 parts, the tongue 32a being in this case attached to one of the sides, in this case at the inner periphery of the side. 34.

  According to a second variant, FIG. 5b, the tongue 32b extends transversely between the upper 29 and lower 30 parts, the tongue 32b being in this case attached to the inner periphery of the upper part 29 in the direction of the lower part 30.

  According to a second variant, FIG. 5c, the device comprises two tongues 32c and 32d each extending transversely between the upper 29 and lower 30 parts, each of the tongues being in this case attached to one of the sides, in this case the tongue 32c is attached at the inner periphery of the side 35, and the tongue 32d is attached at the inner periphery of the side 34.

  In all cases, the tabs 32, 32a to 32d extend in a plane 15 orthogonal to an axis in which the means 28 can be moved relative to the cover 4.

  Thus to unlock the locking means 28, a pressure is exerted along at least one component parallel to a plane formed by the upper surface 16. The tongue such as 32 provided in the means 28 is compressed until it is pushed against an inner periphery the means 28. In this position, illustrated in Figure 6a, the means 28 is no longer opposite the flange 20 of the cavity 9. If a pressure according to a component at least orthogonal to the second portion 11 of the surface upper 16 is exerted, as shown in Figure 6b, then the cover 4 is rotated around the hinge 7.

  If one decomposes more finely the movement operated by the cover when it is driven from the open position to the closed position, in particular in the case where the cover 4 comprises a pin 15, the balance of forces exerted at the hinge 7 would count for a pressure exerted on the outer periphery 16 of the second portion 11, a resistance opposes this force at the inner periphery of the first portion 10, because of the friction of the pin 15 sealed in its orifice 5.

  Knowing that a pressure exerted by a user is generally of the order of 1.5 kg, and in the case where the resistance is greater than this value, to prevent the user from forcing on the cover 4, provision is made to distribute the arms of levers so that by applying a force of the order of 1.5 kg, it still gets the output of the pin 15 of the orifice 5.

  For example, the length of the lever arm of the resistance is chosen to be less than the length of the lever arm of the pressing force, this length being determined relative to an axis orthogonal to the axis 8 of the hinge. Of this choice, generally, the length of the first portion 10 is less than the length of the second portion 11 relative to this axis orthogonal to the axis 8 Alternatively, when such lever arms can not be implemented because of the chosen design, then it is expected to change momentarily, and especially at the very beginning of the application of the pressure, the relative lengths of different lever arms. This can be achieved by changing the axis of the effective hinge at the beginning of the opening of the lid 4. By acting on the elasticity of the hinge 7 and / or the upper surface of the lid 4, which are one and or the other being able to deform by absorbing a part of the stress applied to them, momentary hinge pin 36 is temporarily created, see in particular FIGS. 2a and 6a.

  This temporary hinge pin 36 is obtained by a stand 37 which bears on the seat 6, in this case the stand 37 is arranged at the lower surface 19 of the first part 10 of the cover 4, so that a lever arm 38 connected to the pressure exerted on the second portion 11 makes it possible to compensate for the lever arm 39 related to the resistance caused by the pin 15 at the level of the first portion 10. The rotation of the lid 4 is then in part obtained around the temporary hinge axis 36.

  From the moment when neither the hinge 7 nor the cover 4 are able to absorb the stress by elasticity, then the axis of rotation returns to the axis 8 of the hinge 7, and the lever arms respective 40 and 41 are largely sufficient to obtain the end of the opening of the lid 4. At this stage, the pin is usually already out of the orifice 5, and no more force is opposed to the rotation involved by the pressure on the second portion 11.

  With an embodiment according to this alternative, closing said lid 4 is easy. The lever arm 41 which can be obtained by pressure on the outer surface 16 of the first part 10 is then greater than the lever arm 40.

  Of course, the invention is not limited to the examples which have just been described and it is possible in particular to combine the characteristics of the various exemplary embodiments.

  Throughout the description, including the claims, the phrase having two is to be understood as being synonymous with having at least two, unless the opposite is specified.
