Definitions

  • the field of the invention is that of liquid containers.
  • the invention relates to a device for storing a liquid comprising a container and a stopper remaining integral with the container.
  • the invention finds applications in particular in the field of plastic bottles adapted to the next standards, in particular to European standards, related to the management of waste and its reduction. These standards will require caps to be attached to the container in order to prevent the caps from being lost and ending up in nature rather than being recycled with the container.
  • integral plugs sports type comprising an orifice formed through a boss formed projecting at the plug and a sliding part in the orifice to close or open the orifice.
  • None of the current systems makes it possible to respond simultaneously to all the required needs, namely to propose a technique of cap integral with a bottle, which makes it possible to easily pour out the contents of the bottle, without disturbing a user wishing to drink directly from the neck of the bottle and without causing a splash when the bottle is first opened.
  • the present invention aims to remedy all or part of the drawbacks of the prior art cited above.
  • Such a container corresponds, for example, to a bottle comprising a flared part and a narrower part called the neck in which the neck is formed, making it possible to insert or extract a liquid inside the container.
  • the end of the neck of plastic bottles comprises a ring having a helical helix cooperating with a thread formed inside the skirt of the stopper.
  • the ring is made by injecting a plastic material into a mould, the body of the bottle then being traditionally obtained by blowing the plastic material into a suitable mould.
  • the shoulders formed between the flared part and the neck of a bottle are more or less formed according to the bottle configurations, sometimes even difficult to distinguish, especially when the diameter of the flared part and the diameter of the neck are close or even equal.
  • the cap of the present storage device cooperates in rotation with the ring of said neck between a position of closure of said neck and a position, called opening, leaving said neck at least partially open, the ring having a stop limiting the displacement of an additional stop presented by the stopper.
  • the cap which is rotated with respect to the neck cannot be extracted from the neck of the bottle without damage or application of a significant force.
  • the stopper then remaining advantageously attached to the container can be recycled with the latter.
  • the abutment and the complementary abutment can be of different shapes depending on the connection between the cap and the ring.
  • the stop can only be of the axial type in the direction of the axis of rotation of the plug relative to the ring, for example forming a groove in which the complementary abutment of the cap, such as a lug, is inserted.
  • the axial stress is imposed by the helical connection which is generally formed by threads cooperating with each other, placed respectively inside the skirt and outside the ring.
  • the abutment is then configured to limit the rotation of the cap relative to the ring by a defined angle which can be for example a quarter turn or a half turn, by limiting the travel of the complementary abutment.
  • the abutment and the complementary abutment are generally configured in relief, that is to say in a hollow or a bump, so that one of the two comes into contact with or bears against the other.
  • the abutment of the container is distinct from the abutment formed by the open end of the ring on which the inner face of the lid rests in the closed position to ensure the tightness of the neck.
  • the periphery of the neck ring comprises a circular part, collinear with a circle of radius R, and a so-called truncated part, corresponding to a truncation of said circle over an angle ⁇ .
  • the lid of the cap is generally circular with a truncated part, the skirt of the cap comprising an opening or a hingeable dish along the truncated part.
  • the cap truncated in part with respect to a circular cap can be rotated with the neck ring. It should be emphasized that in the case of the presence of an articulable dish, the articulable dish must be open to allow rotation of the stopper.
  • the rotation of the truncated stopper makes it possible to leave the neck free in the open position, even if the stopper remains fixed to the ring of the neck.
  • the truncated part is for example of slender shape. However, the truncated part can be of any shape.
  • the periphery of the neck is at all points equidistant from the periphery of the neck.
  • the neck ring is generally of constant thickness.
  • the articulable plate comprises a tenon cooperating with a boss presented by the neck ring.
  • the stop and the complementary stop are configured such that the rotation between the closed position and the aperture is less than ⁇ - ⁇ .
  • This maximum rotation makes it possible to prevent the plug from separating from the ring of the neck during rotation, by constraining the contact between the skirt and the ring to a minimum surface area required to maintain the connection between the plug and the ring.
  • the complementary abutment is a lug projecting from the inner face of the skirt, the abutment being presented by the outer surface of the neck.
  • a groove of depth ⁇ is formed outside the ring of the neck of the container, the lug of the stopper sliding in said groove, the bottom of the groove comprising a circular part, collinear with a circle of radius R- ⁇ , or even an elongate part, called truncated, corresponding to a truncation of said circle of radius R- ⁇ over a lower angle ⁇ to ⁇ .
  • the groove makes it possible to narrow the minimum contact diameter of the connection between the plug and the ring and consequently to increase the possible angle of rotation of the plug relative to the ring.
  • the groove also acts as a stop in the axial direction for the lug.
  • the stop and the lug which acts as a complementary stop are configured so that the rotation between the closed position and the open position is less to ⁇ - ⁇ .
  • one end of the groove can be configured to form the stop associated with the opening position of the neck.
  • the lug corresponds to at least part of a crown or a helix formed inside the skirt of the stopper.
  • the crown can for example be formed at the level of the open edge of the skirt of the stopper, by bending the open edge of the skirt towards the inside of the stopper.
  • crown or helix type lug may be discontinuous.
  • the additional stop is a lug projecting from the internal face of the lid, so as to fit into the neck and to come into abutment against a wall of the neck in the open position.
  • the configuration of the projecting lug can make it possible to maintain the connection between the cap and the ring.
  • the lug is preferably positioned at a distance from the skirt that is substantially equal to, preferably slightly less than, the thickness of the ring in order to provide radial stress to the cap.
  • the ring of the circular neck comprises a peripheral, circular or helical groove, forming a abutment for a lug, of the crown or propeller type, the lug forming a complementary abutment projecting from the inner face of the cap skirt.
  • the stopper cooperates with the neck by a helical connection.
  • the stopper cooperates with the neck by a non-slip pivot connection.
  • the stopper is formed for example by a circular groove surrounding the neck, the stopper comprising a ring or a series of lugs, forming a complementary stopper projecting inside the stopper, intended to be inserted into the groove.
  • the ring, also called crown, or the series of lugs is configured to constrain the movements of the stopper in translation along the axis of rotation. Also, the depth of the ring or lugs is determined to prevent the cork from being easily removed from the neck.
  • non-slip pivot connection is currently uncommon on plastic bottles where a helical connection between the cap and the container is rather preferred.
  • the stopper comprises a relief on its internal face, the relief matching the periphery of the neck.
  • This relief makes it possible in particular to ensure the seal between the stopper and the neck, in particular for storing drinks of the sparkling type.
  • the invention also relates to a container and a cap of a storage device according to any one of the preceding embodiments.
  • FIG 1 is a perspective view of an exemplary embodiment of a liquid storage device 100 according to the invention.
  • the storage device 100 comprises a container 110, here a bottle, provided with a neck 120 to the interior of which is formed a neck 130.
  • the bottle can be of any shape, cylindrical in any section, or like the one illustrated in figure 1 , truncated in whole or part of the height of the bottle.
  • An example of a truncated bottle and the associated technical advantages is described in French patent application no. FR2105998 .
  • the neck 120 comprises a ring 125 surrounding the neck 130 and cooperating with a stopper 140 in order to make the container 110 liquid-tight, or even gas-tight when the liquid is of the sparkling type.
  • the ring 125 here takes the truncated shape of the neck 120.
  • the periphery of the neck 130 is also of generally circular shape with a truncated edge 131, like the ring 125 and the neck 120.
  • the stopper 140 comprising a cover 145 and a skirt 160 partly covering the ring 125 of the neck 120, cooperates in rotation with the ring 125 around an axis of rotation 121, for example via a helical connection or non-slip pivot type.
  • the displacement of the stopper 140 is here limited by means of a lug 155 formed for example inside the skirt 160 of the stopper 140, the lug 155 coming into contact with a stop 150 presented by the ring 125.
  • the lug 155 which is a complementary abutment, bears against the abutment 150.
  • the stopper 140 remains integral with the ring 125 by moving between a closed position of the neck 130 which is completely covered by the lid 145 and an opening position of the neck 130 which is at least partly left free to allow the liquid to be introduced or extracted from the container 110.
  • the stopper 140 also has a generally cylindrical shape, having a truncated edge 141 in order to leave the neck 130 partly uncovered in the open position.
  • the truncated shape of the stopper 140 also allows the stopper 140 to have a homogeneous shape with the ring 125. Indeed, in this position, the shape of the stopper 140 being in the continuity of the shape of the ring 125, the cap 140 has few or no points protruding from the shape of the neck 120 and likely to be caught by an external element.
  • the periphery of the ring 125 is partly collinear with a circle of radius R.
  • the open position corresponds in this example to a rotation of the stopper 140 by a quarter turn relative to the closed position of the neck 130.
  • the angle of truncation of the circle of radius R, corresponding to the arc of a circle truncated by the linear part 121 of the periphery of the ring 125 is subsequently denoted ⁇ .
  • the rotation between the closed position and the open position can be constrained by a maximum angle. Indeed, when the truncation angle ⁇ is greater than ⁇ /2, the angle ⁇ of rotation of the stopper 140 relative to the ring 125 of the neck 120 between the closed position and the open position is at the maximum. equal to ⁇ - ⁇ . Beyond this angle of ⁇ - ⁇ , the connection between the stopper 125 and the neck 120 is no longer ensured without the presence of a complementary connecting element, because the so-called contact angle ⁇ corresponds to the zone contact between the cap 125 and the neck 120, is less than ⁇ .
  • the lug 155 (not shown on the figure 2 ) and the stop 150 (not shown on the picture 2 ) are thus configured such that the maximum of the angle ⁇ of rotation is less than ⁇ - ⁇ .
  • the truncation angle ⁇ is preferably less than ⁇ for issues of mechanical connection between the stopper 140 and the ring 125 and the opening of the neck 130.
  • a complementary connecting element can advantageously be added.
  • Such a connecting element may for example be a lug 250 projecting inside the cover 145, so as to form a U in which the edge of the ring 125 slides, as illustrated in picture 3 .
  • the U adjustment is configured to hold the connection between plug 140 and ring 125 in place.
  • the neck 130 is a truncated circle as in the present example, the lug 250 also comes into abutment on the truncated edge 131 of the neck 130.
  • the lug 155 inside the skirt 160 of the cap 140 and the abutment 150 presented by the ring 125 can be omitted in this configuration.
  • the complementary connecting element is configured via cooperation between a groove 260 of depth ⁇ , formed on the outer surface of the ring 125 of the neck 120, and the lug 155 which slides in the throat 260, as shown in figure 4 which is a view from above and in figure 5 which is a cross-sectional view centered on groove 260.
  • the figure 5 is illustrated with a circular groove 260 in order to simplify the understanding of the illustration.
  • the groove 260 can be made in the shape of a helix in order to allow a helical connection between the plug 140 and the ring 125.
  • the lug 155 is here formed along the entire length of the curved edge 142 of the skirt 160, in order to obtain greater contact with the groove 260.
  • the depth ⁇ of the groove 260 makes it possible to increase the contact angle ⁇ by reducing the minimum contact diameter of the connection between the plug 140 and the ring 125, to a circle of diameter R- ⁇ .
  • the circle of diameter R- ⁇ also includes a truncated edge when: ⁇ ⁇ R 1 ⁇ cos ⁇ 2
  • the circle of diameter R- ⁇ thus comprises a truncated edge when the depth ⁇ is less than 0.3*R.
  • the groove 260 can advantageously be configured with a depth ⁇ greater than 0.37*R, for example equal to 0.4*R, in order to obtain an angle ⁇ less than ⁇ /2, thus allowing the stopper 140 to turn advantageously by any angle, for example a quarter turn or a half turn, relative to the ring 125.
  • the opening of a half-turn modulo 2 ⁇ is generally preferred in order to obtain an optimal opening of the neck 130.
  • An optimum for the couple ( ⁇ , ⁇ ) can be calculated in order to maximize the flow in the opening position of the neck 130, the flow being a function of the angle ⁇ of maximum opening of the neck 130, of the pressure drop at the level of the internal section of the neck at the level of the groove 260, and the pressure drop linked to the height of the cover 145 with respect to the neck 130.
  • the height of the lid 145 relative to the neck 130 is linked to the type of connection chosen between the stopper 140 and the ring 125. It may be a fixed and zero height in the context of a connection non-slip pivot or variable height in the case of a helical connection.
  • the lug 155 sliding in the groove 260 advantageously corresponds to at least part of a crown in the case of a non-sliding pivot connection or a helix formed inside the skirt 160 of the stopper 140 in the case of a helical connection.
  • Pin 155 may be independently continuous or discontinuous.
  • the straight edge 141 of the skirt 160 is either removed, for example at the time of manufacture or during the first use of the stopper 140, thus forming an opening, or configured in order to articulate with respect to to the cover 145 or to the skirt 160 of the stopper 140, thus forming an articulable dish.
  • the straight edge 141 corresponds to a tongue articulating with respect to the curved edge 142 of the skirt 160, adopting a cylindrical shape.
  • the straight edge 141 corresponds to a tongue hinged relative to the cover 145.
  • a pin 315 formed inside the tongue 310 can make it possible to improve the sealing of the storage device 100 in the closed position, by cooperating with a boss 316 presented by the neck 120.
  • the cooperation of the pin 315 with the boss 316 makes it possible to provide a constraint along the axis of rotation 121.
  • the stopper 140 can be in a non-sliding pivot connection with the ring 125, as illustrated in section in figure 7 .
  • the lug 155 being constrained along the axis of rotation 121 by the stop 150 formed by a wall of a circular groove 410 configured on the periphery of the ring 125 of the neck 120.
  • the stopper 140 can cooperate with the ring 125 via a helical connection, formed by two complementary threads, one formed inside the stopper 140 and the other on the periphery of the neck 120.

  • the positions of the lug 155 and of the abutment 150 are configured at predetermined points additional screw threads in order to limit the travel of the helical connection and prevent the stopper 140 from being easily extracted from the neck 120, while respecting the maximum allowable angle of rotation to maintain the helical connection.
  • the helical connection can be ensured only by the connection between the groove 260 and the lug 155.
  • the abutment 150 can then be configured as an end of the groove 260, as shown in figure 9 which is a sectional view of the ring 125 with the cap 140 in the open position. It should be emphasized that thanks to the helical connection, an additional space allowing the flow of the liquid is obtained. This additional space corresponding to a distance of the stopper 140 from the end of the neck 130, has a height h.
  • the seal between the stopper 140 and the neck 130 can be improved by adding a relief 550 on the internal face of the stopper 140, facing the neck 130.
