SUMMARY

A need exists to benefit from a closure cap that can open easily while providing satisfactory closing.

Exemplary embodiments of the invention provide a closure cap comprising:

a lid provided with a closure pin comprising a portion in relief;

a base portion onto which the lid is hinged, a hinge connecting the lid to the base portion, the base portion comprising:

• • a dispenser orifice configured to be closed by the closure pin when the lid is closed and the closure pin is in a closed position, the pin bearing in leaktight manner against an annular surface of the dispenser orifice in the closed position:
  • a fastener portion extending from the annular surface and configured to snap-fasten on the portion in relief of the closure pin when the pin is in the closed position.

The portion in relief may comprise an annular groove.

The fastener portion may comprise at least one elastically-deformable tab, preferably a plurality of elastically-deformable tabs.

The at least one elastically-deformable tab may extend from the annular surface substantially below the annular surface inside the base portion.

The fastener portion need not extend all around an axis of the dispenser orifice, and may extend for example only within a perimeter excluding a portion of the dispenser orifice adjacent the hinge. This may range for example between 180° and 270° of the perimeter.

The hinge, the lid and the base portion may be molded in a single piece.

In an exemplary embodiment, the fastener portion comprises at least one and preferably exactly three elastically deformable tabs configured to snap fasten on the portion in relief.

A first one of the three elastically deformable tabs may extend on a side of the dispenser orifice opposite to the hinge, and the two other elastically deformable tabs may extend opposite each other. A line passing through median planes of these two other elastically deformable tabs may be parallel to a pivot axis of the hinge.

The at least one elastically deformable tab may comprise at least one arcuate tooth configured to snap fasten on the portion in relief.

The base portion may comprise a skirt configured for mounting on a neck of a receptacle. The skirt may comprise projections configured to snap fasten on the neck.

In some exemplary embodiments, the lid is lifted into the open position manually by the user.

In some other exemplary embodiments, the lid moves toward the open position subsequent an action of the ser on an opening control element.

The opening control element may comprise a skirt that surrounds at least a portion of the base portion, and that is connected to the base portion via at least one elastically-deformable connection element.

In an exemplary embodiment, the dispenser orifice is defined by an annular surface that is extended downwards by at least one elastically-deformable tab that is arranged to snap-fasten on a closure pin carried by the lid.

The annular surface need not have an extension that co-operates with the closure pin on the side remote from the face of the opening control element on which the user presses in order to open the lid.

The annular surface may be extended by a plurality of tabs that are arranged to snap-fasten on the closure pin other than on the side adjacent the hinge or the side which is remote from the face of the control element on which the user presses in order to cause the lid to open.

This facilitates opening the lid without being hindered too much. The lid is not hindered by the pin catching on the base portion, which catching effect would tend to get worse the more the user presses.

The skirt of the opening control element may act as a presser, so as to enable the user to control opening, while concealing the top portion of the receptacle body onto which the cap is mounted. The skirt may provide the user with a relatively large presser surface, thereby increasing comfort in use.

In exemplary embodiments of the invention, the elastically-deformable connection element(s) may act as resilient return means for returning the skirt into its initial position after it has been actuated by the user.

In exemplary embodiments, the cap may be made in such a manner as to reduce the risk of dirt accumulating, e.g., as a result of the absence of a cutout surrounding the outside of the dispenser orifice, and as a result of it being possible for there to be no external recess, similar to prior art recesses, for guiding the opening control element.

In exemplary embodiments of the invention, the entire cap is molded as a single part as a result of the presence of the elastically-deformable connection element(s). The deformable connection element(s) enable(s) various portions of the cap to be disposed in a configuration that makes them easy to mold, and said element(s) can then deform while the cap is being mounted on the receptacle body, so as to take up their final configuration.

In exemplary embodiments of the invention, the opening control element is not made integrally with the base portion.

The opening control element and the base portion may be made separately, and then assembled. The base portion and the opening control element may be made in a single mold, in such a manner as to enable them to be assembled together while the cap is being removed from the mold.

The neck of the receptacle may include at least one portion in relief for angularly positioning the base portion of the cap relative to the body of the receptacle. By way of example, the portion in relief may be in the form of a spline that extends, at least in part, along the neck, e.g., substantially symmetrically relative to a mid-plane that is perpendicular to the pivot axis of the lid. By way of example, the base portion of the cap may include at least one notch in which the above-mentioned spline can be engaged while the base portion is being mounted on the receptacle body.

The base portion may be fastened onto the receptacle body by snap-fastening, in an embodiment of the invention. On its inside surface, the base portion may include at least one portion in relief for snap-fastening on a corresponding portion in relief formed on the neck in the proximity of its base, for example.

The base portion may include an annular sealing lip for bearing against the inside surface of the neck.

The skirt of the opening control element may be extended, in particular at its top portion, by an inwardly-directed rim.

In another exemplary embodiment of the invention, the connection elements are molded in such a manner as to be capable of being brought to snap-fasten on the base portion while the cap is being removed from the mold.

The lid may be molded with the base portion or it may be fitted thereon.

In an exemplary embodiment in which the base portion and the opening control element are molded as a single part, the lid may be molded with the base portion or it may be fitted on the base portion and fastened thereon, e.g., by snap-fastening.

In an exemplary embodiment in which the control element is assembled with the base portion, e.g., after molding, the lid may be molded integrally with the base portion.

The hinge connecting together the lid and the base portion may advantageously include at least one spring-forming tongue that assists the opening movement of the lid. The tongue may be bent, and it may pass through a maximum stress state when the lid is in an intermediate position between the closed position and the open position.

The opening control element may when present be arranged to act on the spring-forming tongue, when actuated by the user, so as to push said tongue to the point of triggering the spring effect.

On the hinge side, the opening control element may include when present a tab for pressing on the spring-forming tongue. The tab may present a bracket shape, so as to make it possible to press on the spring-forming tongue at a location that is higher than the pivot axis of the lid.

The opening control element may also advantageously be arranged when present to act directly on the lid, when actuated by the user, so as to make it easier to disengage a closure pin, carried by the lid, of the dispenser orifice of the base portion.

In an exemplary embodiment of the invention, the opening control element may be arranged to act on a portion in relief that is carried by the lid in a region of said lid that is situated substantially remote from the hinge. By way of example, the lid may include a tooth on its bottom face in the proximity of its edge remote from the hinge, and the plate of the base portion may include an opening enabling the tooth to co-operate with the opening control element when the user presses on said opening control element, so as to displace it towards the hinge. By way of example, the above-mentioned rim of the opening control element may include a notch in which the tooth of the lid is engaged, and the bottom wall of the notch may come to bear against a sloping face of the tooth when the opening control element is first displaced, so as to cause the lid to start pivoting.

In the closed position and when the opening control element is at rest, the lid may be arranged in such a manner as to extend set back from the opening control element on the side remote from the hinge, or, in contrast, it may project in front of the opening control element.

In order to reduce the risk of uncontrolled opening, the opening control element may be configured in such a manner as to be capable of being displaced through a non-zero stroke before acting on the lid. With this configuration, the edge of the lid may project in front of the opening control element before said opening control element starts to act on the lid.

The invention also provides a receptacle comprising a body and, fastened onto the body, a closure cap as defined above.

In some embodiments, the receptacle body may be arranged to present a shouldered top wall, so as to guide the opening control element in displacement.

In another of its aspects, the invention also provides a receptacle comprising a closure cap, and a body onto which the closure cap is fastened, the closure cap comprising:

a lid provided with a closure pin comprising a portion in relief; and

a base portion onto which the lid is hinged, a hinge connecting the lid to the base portion, the base portion comprising:

• • a dispenser orifice configured to be closed by the closure pin when the lid is closed and the closure pin is in a closed position, the pin bearing in leaktight manner against the annular surface of the dispenser orifice in the closed position; and
  • a fastener portion extending downward along the annular surface and configured to snap-fasten on the portion in relief of the closure pin when the pin is in the closed position.

In another of its aspects, and independently or in combination with the above, the invention also provides a method of manufacturing an article comprising first and second assembled-together parts, and in which:

the two parts are molded in a single mold that is provided with at least one extraction pusher, the second part being disposed in the mold relative to the first, in such a manner that, after molding, displacement of the extraction pusher is accompanied by displacement of the second part relative to the first, and by the parts being fastened together, e.g., snap-fastened.

By way of example, the first part is the base portion of the above-defined closure cap, and the second part is the opening control element.

The first part may be molded in a first material, and the second part in a second material that is different from the first, e.g., of different color.

The base portion may be molded integrally with the lid.

At least one slider may be provided in the mold, defining, at least in part, the cavities that are used to mold the two parts. The slider may be displaced, so as to enable the extraction pusher to act.

The above-mentioned surface may be extended by one or more elastically-deformable tabs that are arranged to snap-fasten in an annular groove formed in the closure pin.

The surface need not have an extension that co-operates with the closure pin on the side remote from the face of the opening control element on which the user presses in order to open the lid. Thus, opening the lid is not hindered by the pin catching on the base portion, which catching effect would tend to get worse the more the user presses.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The receptacle 1 shown in FIGS. 1 and 2 comprises a body 2 onto which there is fastened a closure cap 3.

The body 2 is for example in the form of a flexible tube.

In the embodiment shown, the apparent top portion of the body 2 presents a substantially circular cross-section.

The closure cap 3 comprises a base portion 5 having a tubular skirt 5a and a top wall 5b provided with a dispenser orifice 6 and a lid 7 that is hinged onto the base portion 5 about an axis Y.

The receptacle 1 comprises a neck 2a shown in FIG. 3 on which the base portion 5 is fastened, for example snap-fastened.

The base portion may comprise a mounting skirt 5e to snap-fasten on the neck 2a.

The mounting skirt 5e may be continuously tubular or may comprise longitudinal slots.

The base portion 5 comprises a sealing lip 5f that contacts the internal surface of the neck 2a.

In variant embodiments, the base portion and the neck are fastened as disclosed in U.S. 2005/0173366 A1, which is incorporated herein by reference.

In the example of FIGS. 1 and 2, the skirt 5a presents a substantially circular cross-section.

The lid 7 is connected to the base portion by a film hinge 10 comprising two portions that are disposed on either side of a spring-forming tongue, sometimes referred to as a toggle. The hinge portions pass through a maximum stress state in an intermediate position between the closed position and the open position, in such a manner as to assist the opening movement of the lid 7 and ensure that, once open, said lid maintains its position.

The lid 7 includes a pin 14 for closing the orifice 6, said pin being provided as shown in FIG. 3 with at least one portion in relief 15 that is configured to snap-fasten on a fastener portion 16 of the base portion 5 when the lid 7 is closed.

The dispenser orifice 6 may be defined by an annular surface 180, e.g. cylindrical, that is extended downwards by tabs 181 that include teeth 182 for snap-fastening in the corresponding groove 183 of the closure pin 14.

The annular surface 180 may be extended by four tabs 181, each provided with a corresponding tooth 182, as shown in FIG. 4A.

Each tooth 182 of the corresponding tab 181 may have as shown a chamfered end defining a surface 181a that tapers inwardly and upwardly on FIG. 3.

The end of the pin 14 is defined in the shown embodiment by a wall 14a that is thinner than a wall 14b above the groove 183.

The contact between the wall 14b and the annular surface 180 provides a tight seal in the closed position of the lid, as shown in FIG. 3.

The pin 14 has, in the shown embodiment, a shape symmetrical about its longitudinal axis.

The pin 14 is hollow in the described embodiment but may in a variant (not shown) not be hollow.

The lid 7 may be held in the closed position only by the snap-fastening of the pin 14 in the dispenser orifice 6.

In a variant (not shown), the lid 7 comprises a latch member that snap-fastens on a corresponding relief of the base portion.

On the hinge side of the lid, the surface 180 need not be extended by a tab 181 provided with a tooth 182, so as to make it easier to open the lid, as shown in the variant of FIG. 4B.

In the example of FIG. 4B, the pin 14 comprises a tab 181 that is opposite to the hinge 10 and two other tabs 181 that are facing each other. A line M joining the centers of these two tabs may extend parallel to the pivot axis Y of the hinge.

In the variant of FIG. 4C, the fastener portion 16 comprises only two tabs 181 provided each with a corresponding tooth and facing each other. These two tabs 181 correspond to the two tabs facing each other of the embodiment of FIG. 4B.

In the embodiment of FIG. 4D, the fastener portion comprises only one tab 181 provided with a tooth 182, on the side of the dispenser orifice opposite to the hinge 10.

The skirt may be provided in a variant (not shown) with a recess on the side opposite to the hinge to make it easier to the user to lift the lid by a thumb.

A variant embodiment of the receptacle is described as shown below with reference to FIGS. 5 to 15.

In this embodiment, the base portion 5 may include firstly a plate 20 that is elongate along a major axis W, and on the top face of which the orifice 6 opens out, and secondly a portion 22 that extends below the plate 20, and that is used for fastening onto a neck 24 of the receptacle, visible in FIG. 12.

In the embodiment under consideration, the portion 22 is in the form of a tubular mounting skirt of axis K, configured for snap-fastening on a corresponding flange 26 of the neck 24, as shown in FIGS. 9 and 12.

In the embodiment under consideration, the portion 22 further includes two notches 28 (FIG. 32) that are arranged to receive splines of the neck 24, in such a manner that the major axis W of the plate 20 is substantially parallel to a major axis of the body 2.

An annular sealing lip 33 for bearing against the inside surface of the neck 24 is connected to the bottom face of the plate 20.

The closure cap comprises an opening control element 8 including a tubular skirt 40 extending around the entire neck 24. In the embodiment under consideration, the tubular skirt 40 presents a cross-sectional shape that is substantially geometrically similar to the shape of the body 2, as can be seen in FIGS. 5 and 6.

The skirt 40 is extended at its top portion by an inwardly-directed rim 41. The rim 41 is covered in part by the plate 20 when the cap 3 is fastened onto the neck of the receptacle 2, as can be seen in FIG. 7.

In the shown embodiment, the opening control element 8 is connected to the base portion 5 by arms 110, each extending between two opposite regions 111 and 112 of the inside edge of the rim 41, as can be seen in FIGS. 8 and 10.

While the user is not exerting any pressure on the opening control element 8, each arm 110 presents a curved portion 114 that is adapted to match substantially the shape of the portion 22 of the base portion that is used for fastening said base portion on the neck 24 of the receptacle.

The curved portions 114 are connected to the edge 111 via portions 120 that are parallel to each other, and that are both perpendicular to the major axis W. The curved portions 114 are connected to the edge 112 via rectilinear portions 122 that diverge a little towards the edge 112.

When the opening control element 8 is in place on the base portion 5, the arms 110 are snap-fastened between the plate 20 and portions in relief 148 carried by the portion 22, as can be seen in FIGS. 12 and 14.

When the user presses on the skirt 40 in order to cause the lid to open, the arms 110 deform elastically, as shown in FIG. 15.

At the end of the displacement of the skirt 40, each bend 126, formed at the junction between the curved and rectilinear portions 114 and 122, remains on the same side of the half plane containing the axis of the dispenser orifice 6 and the major axis W, such that when the user releases the opening control element 8, the arms 110 tend to return said opening control element into its initial position, shown in FIG. 14.

The body 2 of the receptacle may include a recess 140, as shown in FIG. 5, and the skirt 40 may present, on the side where the user presses, an extension 141 that matches the shape of the recess 140, as shown in FIGS. 6 and 7.

The final clearance between the plate 20 and the rim 41 may lie in the range of 0.2 mm to 0.5 mm, for example.

On the side remote from the surface on which the user presses in order to control opening, the opening control element 8 includes a tab 60 for acting on the spring-forming tongue 12, so as to push said tongue to its trigger point, thereby causing the lid to open.

The opening control element 8 may also be arranged to act on a portion in relief 63 of the lid 7, so as to cause the lid to start rising, and in particular cause the closure pin 14 to disengage.

In the embodiment under consideration, the portion in relief 63 is in the form of a tooth formed in the proximity of the edge of the lid that is remote from the hinge 10.

On its edge remote from the hinge 10, the plate 20 includes an opening 66 through which the tooth 63 passes. The rim 41 may come to bear against a sloping face of the tooth 63, in such a manner as to cause the lid to rise while the skirt 40 is being displaced.

In the embodiment shown, the tab 60 presents a bracket shape, and its free end 72 is situated just above the pivot axis Y of the lid when the closure cap 3 is in place on the receptacle.

When the user presses on the opening control member 8 in the direction of arrow O of FIG. 6, the bracket-shaped tab 60 presses, via its end 72, on the spring-forming tongue 12 until said tongue passes through its maximum stress state, the opening movement of the lid being completed by the energy that has accumulated in the spring-forming tongue 12 being restored.

The closure cap 3 may be manufactured in a single mold, as described below with reference to FIGS. 16 to 27.

A mold 200 that is used may comprise a first portion 201 and a second portion 202 that define a first cavity 203 for molding the base portion and the lid, and a second cavity 204, that does not need to be in communication with the cavity 203, for molding the opening control element 8.

In the embodiment under consideration, the material is injected into the cavities 203 and 204 via respective injection channels 205 and 206.

The cavity 203 is defined between firstly parts 210 and 218 belonging to the second portion 202 of the mold, and secondly lateral sliders 211 and 212 and parts 213 and 215 belonging to the first portion 201 of the mold.

The cavity 204 is defined between firstly the part 210, and secondly the part 215, the sliders 211 and 212, a part 220, and an extraction pusher 219.

Once the mold has been closed, the cavities 203 and 204 can be filled.

This can be done using the same thermoplastic material with different colors and/or using chemically different materials.

Injection into the cavities 204 and 203 can take place simultaneously, as shown in FIG. 18.

After injection, the second portion of the mold 202 is separated from the first, as shown in FIG. 20 . The sliders 211 and 212 can be removed, as shown in FIG. 22.

Then, as shown in FIGS. 24 and 25, the pusher 219 can be raised, so as to cause the arms 110 to snap-fasten behind the teeth 148 of the portion 22 of the base portion 5.

The closure cap can then be completely extracted by extending the upwards stroke of the pusher 219, as shown in FIGS. 26 and 27.

Regardless of how the opening control element 8 is connected to the base portion 5, the skirt 28 of the opening control element 8 can, as shown in FIG. 28, be made in such a manner that its depression stroke before the tooth 63 comes to bear against the edge of the rim 41 takes place over a distance M that is greater than the distance m over which the skirt 40 might project forward relative to the free edge 170 of the lid 7.

The edge 170 can thus impede the skirt 40 being pressed in accidentally while the receptacle is being transported for example, by coming into register with the skirt 40 before said skirt bears, via the rim 41, against the tooth 63, as shown in FIGS. 29 and 30.

The cap can be fastened onto the neck other than by snap-fastening, e.g., by clamping.

The receptacle body and the opening control member may also co-operate in some other way, with portions in relief other than the shoulders being formed on the top transverse wall of the receptacle.

Although the present invention is described above with reference to particular embodiments, it should be understood that those embodiments are purely illustrative of the principles and applications of the present invention. It should therefore be understood that numerous modifications could be applied to those illustrative embodiments, and that other embodiments could be envisaged without going beyond the spirit and the ambit of the present invention.

The expression “comprising a” should be understood as being synonymous with “comprising at least one”, unless specified to the contrary.
