Abstract

The capsule (1) consists of a deformable membrane (2) with its base closed by a seal (3) to form an enclosed volume (V) for at least one substance (S) that is released when the seal is pierced by an integral rupturing component (4). After the seal has been pierced a mechanical pressure is applied to the membrane to expel the substance(s) from the capsule into a container that is fitted with a cap holding the capsule, enabling the substance(s) to be mixed with the container's contents.

Description

DESCRIPTION

  The present invention relates to a capsule intended to be mounted in a cap for a neck or neck container intended for dispensing liquids or pasty products, in particular for bottles of mineral water and the corresponding cap and container.

  More specifically, the cap provided with a capsule according to the present invention is intended to contain, in a hermetically sealed compartment of the container thus clogged, a substance or specific composition intended to be mixed with the contents of said container just before use or consumption. of the last.

  The plug of the present invention can in particular be used to plug plastic bottles commonly called plastics (for example PET) intended to contain all kinds of liquid food or not, more or less fluid, such as, for example, mineral water, fruit juice, milk drinks, etc. but also sauces or condiments (ketchup, mustard, vinaigrette ...) or non-food liquids (cleaning products, detergents ...).

  In this particular field, a number of corks having compartments containing a substance, in particular a food substance, intended to be added to the contents of the receptacle which generally contains a beverage such as water or milk, for example, are already known. for the preparation of energy drinks or baby bottles.

  However, all current plugs have a number of disadvantages more or less troublesome.

  A first type among these known plugs has a capsule or tank sealed by a membrane or detachable tongue and fixed on the upper part of said plug fitted to a container. To add the substance contained in the tank to said container, it is necessary to unscrew the cap, to remove the membrane or tongue 30 closing said reservoir to create an opening for said substance, to turn the cap to pour said substance into said container and finally, to screw the cap on said container to be able to shake it and thus mix the substance with the contents of the latter. The use of such a type of cap therefore requires many tedious steps, some of which, such as that of turning the cap to release the substance in said container, may require some dexterity to avoid pouring the substance next to this last.

  Another type of plug has a capsule or reservoir 5 releasing a solid substance in the form of a tablet via a pressure exerted by a finger of the user on said capsule. However, this type of plug has sealing problems, being reminded that the contents of the container must not accidentally come into contact with the substance enclosed in the capsule. These problems are solved in this type of plug by the presence of a sealing cap attached to the neck of the container. In a first embodiment of this cap, the user, to release the substance, first unscrews the cap to remove the cap, then puts the cap on the container and releases the tablet from the capsule by pressing on the latter . In a second variant, the user can remove the lid, while the cap is attached to the container. In both cases, many tedious steps are needed again to release the substance. In addition, another disadvantage is that the operculum of the capsule for releasing the substance only functions well when this substance is in the form of tablets or hard pellets.

  To limit the number of steps necessary for the release of the substance, it has been designed a type of plug in which the substance, in the form of a tablet or a rigid tablet, is between a deformable upper membrane on which the pressure is exerted for releasing said substance, and a lower seal acting as a sealing member.

  The lower lid is torn by the tablet when the user exerts pressure on the upper membrane.

  However, the rigidity of the cap is a critical parameter insofar as the latter must be both low enough to allow easy release of the substance (preferably whatever its state) and sufficiently high to allow said operculum to withstand the pressure that may be exerted on the latter by the contents of the container when it is compressed during the handling steps of the container. Indeed, when the rigidity of the lid is too low, it occurs breaks thereof during the handling steps, and the substance accidentally mixes with the contents of the container. - 3

  When the lid is rigid enough, the pressure to be exerted by the user or consumer on the lid to release the substance must also be high, which can be disadvantageous for some people. Ideally, this pressure transmitted to the seal through the substance should be identical regardless of the form and constitution of the substance. However, in the use of a substance in powder form, for example, the force exerted on the elastic membrane is transmitted in a reduced manner to the lid and is not always sufficient to tear the latter in order to release the substance.

  The main disadvantage of this type of plug is that it is limited to the use of substances in the form of tablets or rigid pellets which alone are capable of transmitting substantially completely the force exerted by the finger to the cap. This type of stopper can not therefore be applied in the case of liquid substances or in the form of powder. In addition, the rupture of the lid is a function of the shape of the substance, which excludes any reproducibility of said rupture.

  The present invention aims at overcoming at least some of the disadvantages of known capsules and caps with caps and is intended to provide a capsule and a stopper to minimize the risks of accidental rupture of the seal allowing the substance to be isolated. the contents of the container to which it must be added and allowing a frank and reproducible facilitated rupture of said seal by the user who is as independent as possible from the state or the physical constitution of said substance.

  Indeed, the rupture of the sealed seal should ideally be for any type of substance to be added to the contents of the container, particularly in the case of partially filled capsules containing substances that do not always allow to transmit a part sufficient mechanical stress exerted by the user capable of breaking the sealing cap.

  This can especially be the case for very fluid liquids, highly deformable or compressible solids such as fine powders, highly friable granules, etc. Furthermore, the plug according to the invention must be able to be used with little effort and little manipulation by a single hand of the consumer, the opening preferably not having to cause the formation of spare parts.

  The present invention therefore relates to a sealed capsule consisting essentially of a deformable membrane sealed at its base by a pierceable cap so as to define a sealed volume intended to contain at least one substance between said deformable membrane and said cap, characterized in that it has at least one integral breaking means of said pierceable cap capable of tearing it for a release of an effective quantity of substance (s) following a sufficient deformation of said deformable membrane due to an external mechanical force exerted on the latter .

  It also relates to a cap for a neck or neck container for the distribution of liquids or pasty products, in particular for mineral water bottle, characterized in that it consists essentially of a base intended to be fixed on said container and closing said container via a capsule according to the invention reported in a sealed manner on said base, the deformable membrane of said capsule being itself covered by a rigid protective cover resting on a base part annular attached to said base, the lower base of said capsule being formed by the pierceable cap, a sealed effective volume filled with at least one substance to be added to the contents of the container before consumption being thus defined between the deformable membrane and said cap of said capsule, an effective amount of substance (s) being released into the contents of the container during a rupture of the seal due to a sufficient deformation of the deformable membrane.

  It also relates to a neck or neck container for dispensing liquids or pasty products, in particular mineral water, characterized in that it comprises a capsule according to the present invention.

  Referring first to Figure 1 which shows a schematic side elevational view and sectional view of a first embodiment of the capsule according to the invention.

  In the embodiment described and shown, the sealed capsule 1 essentially consists of a deformable membrane 2 sealed at its base by a cap 3 pierceable so as to define a sealed volume V intended to contain at least one substance S between said deformable membrane 2 and said lid 3 is characterized in that it has at least one integral breaking means 4 of said pierceable lid 3 capable of tearing it for release of an effective quantity of substance (s) following a sufficient deformation of said membrane deformable 2 due to an external mechanical force exerted on the latter.

  The incorporation into the very bosom of said capsule 1 of the breaking means 4 makes it possible to manufacture a one-piece cap 1 ready to be mounted in the stopper chosen to seal the desired container which does not require the provision of an additional external element for the rupture. of the operculum 3. - 7

  According to a first particularly simple and economical embodiment, the capsule 1 according to the present invention is characterized in that the breaking means 4 is made in the form of a pre-cut 5 of the lid 3, namely at least a point or a preferred breaking line of the latter.

  Advantageously, the pre-cut 5 is made in the form of a set of preferential rupture lines arranged in the shape of a star, preferably centered on said lid 3.

  In this way, a tear opening of the operculum 3 is ensured which is the easiest and reproducible possible.

  Another example of pre-cut 5 cross-shaped has been shown for guidance in Figure 2, but other geometries may also be suitable.

  The actual pre-cut can be carried out by any method usually used, known per se, in particular by laser cutting, stamping, etc. Preferably, the deformable membrane 2 is made of PVC, a resilient material, allowing the user to deform sufficiently, for example with a finger, to succeed in breaking the lid 3 and thus release the substance or substances S in the content of the container R. The shape of the deformable membrane 2 itself may be unspecified even if an overall shape of the type of that of a bell, preferably a bell whose apex is flat, for example disk-shaped, d oval, etc., may be preferred.

  According to another feature not shown, the deformable membrane 2 may comprise at least one means of preferential deformation of the latter made in the form of a point, a line or a preferred deformation surface, for example, under the form of a recess in the form of a groove portion of substantially semi-cylindrical section 30 located on the side of said deformable membrane 2. This means allows to create a point, a line or a priming surface and facilitating the deformation of the remaining deformable membrane 2 to achieve the desired objective, namely a concentration of forces leading to a sufficiently marked deformation of said deformable membrane 2 which allows to ensure a tear or a sufficient rupture of the lid 3 to allow the passage of the or 8 substances S contained in the sealed volume V and intended to be added to the contents of the container provided with the psule 1 according to the invention.

  In the preferred example referred to above, the user's thumb or finger first pressing the deformable membrane 2 at the location where the preferential deformation means (s) (which are located at a convenient location of access for the consumer, for example at a level close to the vertex), initiates a relatively easier deformation of the deformable membrane 2 which propagates to the remaining, more rigid surfaces, dragging them into the deformation movement whose magnitude becomes greater. rapidly sufficient to cause a significant opening opening for the substance or substances S in the pierceable lid 3.

  In the case where the deformable membrane 2 is made of a flexible or elastic material, such as a natural rubber, it is not excluded that said membrane can return to its original shape when the pressure exerted by the user's finger ceases. , thus preserving the original aesthetic appearance of the cap.

  Of course, other deformable materials fulfilling the same function may also be suitable, even if PVC is preferred, in particular because of its physico-chemical properties which are particularly suitable for the use described.

  It goes without saying that the material or materials used for the realization of the capsule 1, the plug and more particularly that or those used for the production of the deformable membrane 2 and the lid 3 will have to be chemically and physically compatible with the nature. the liquid or pasty content of the container R thus clogged, respectively with the substance or substances S contained in the sealed volume V delimited by said deformable membrane 2 and said seal 3. In addition, if the container R blocked by the stopper according to the The invention is intended to contain a liquid or pasty food product, it will also be necessary to ensure that the aforementioned materials are food grade and that the marketed clogged product meets the applicable hygiene standards.

  Thus, a single operation is sufficient, after the opening of the protective cover 19 (see for example Figures 18 and 19), to transfer the substance or substances S in the container R. The opening operation of said cover of protection 19 can also be achieved by one hand, for example, by grasping the container R in the palm and disengaging said protective cover 19 by the action of the thumb of the same hand. FIG. 19 illustrates a cap provided with a capsule of the type of that of FIG. 1 when the protective cover 19 has been opened, the deformable membrane 2 depressed sufficiently so that the cover 3 is torn, the substance or substances S falling then in said container R. For closure, the index returns the protective cover 19 on the base part 20 until "click" closing.

  The constitution of the base part 20 and the opening and closing means 33, 34 will be detailed later.

  According to another characteristic, the capsule 1 according to the invention is characterized in that it comprises at least one intermediate piece 6 provided between said deformable membrane 2 and said lid 3, said intermediate piece 6 having at least one breaking means 4 of FIG. said deformable membrane 2 which can be activated during a sufficient deformation of the latter.

  As shown, for example in FIGS. 3 and 4, a capsule 1 according to the invention made according to a second embodiment is characterized in that said at least one intermediate piece 6 is made in the form of a ring 7 disposed between the deformable membrane 2, preferably substantially bell-shaped and more preferably whose apex is flattened, and the seal 3 sealing said volume V, said ring 7 having, as a means of rupture 4, at least a portion surface 8 delimited in said ring 7 so as to form a valve articulated with respect to said ring 7, said valve being able to pivot towards the cap 3 in order to pierce it during a sufficient deformation of said deformable membrane 2.

  According to a third embodiment shown in FIGS. 5 to 7, the capsule 1 according to the invention can be characterized in that said at least one intermediate piece 6 is made in the form of a ring 7 disposed between the deformable membrane 2 , preferably substantially bell-shaped and more preferably with a flattened apex, and the seal 3 sealing said volume V, said ring 7 having, as the breaking means 4, several surface portions 8, 8 ', preferably interconnected by at least one bridge 10 and delimited in said ring 7 so as to form, for each surface portion 8, 8 ', a valve hinged relative to said ring 7, each valve being rotatable , after rupture of the bridge or bridges 10 which connect them, towards - 10 the seal 3 in order to pierce it during a sufficient deformation of said deformable membrane 2.

  As can be seen in Figures 10, 11, 14, 15 and 22, the end of the breaking means 4 opposite the hinge 9 of the pivoting valve 5 formed or the attachment of said breaking means 4 on the intermediate piece 6 may be provided with a thin tie or bridge 10 'acting as a breaking bridge which secures said means 4 as the plug is not actually used.

  This is the case as long as the deformable membrane 2 has not been sufficiently deformed (depressed) to transmit the mechanical force either by coming into contact itself or to transmit the pressure via the substance S to the lid 3 or on the surface of a support 14 as shown in Figure 10 and described in more detail below, and that the force thus transmitted is not sufficient to break this bridge 10 'or a bridge 10 which connects two 15 portions of surfaces between them (see Figures 6 and 9), comparatively lower effort than that required to pierce the lid 3.

  Advantageously, said ring 7 and said surface portions 8, 8 'are made by injection of a synthetic material, preferably polyethylene, at or in the immediate vicinity of the bridge or bridges 10, 10' of rupture.

  As can be seen in the embodiments of FIGS. 8 and 9, the capsule 1 according to the invention is further characterized in that at least a portion of the free contour of said surface portions 8, 8 'has one or more parts sharp-edged 11, of the teeth type, facilitating the piercing of the operculum 3.

  This facilitates, if necessary, the rupture of said seal 3 which otherwise has to tear without being assisted. The shape of the pivoting valve and / or the breaking means 4 as well as the number of these are determined according to the tear resistance provided by the seal 3 which is usually made in the form of an aluminum film. optionally plasticized or the like.

  By way of nonlimiting example, protruding teeth are shown for the breaking means 4, but other projecting and cutting geometries are also possible, for example in the form of projecting protruding vertical points or in the thickness of said flap. pivoted towards the operculum 3. - it

  According to the embodiment variant illustrated in Figures 14 to 17, the breaking means 4 has at least one substantially vertical salient element 12 directed towards the cap 3 and facilitating the drilling of the latter. This variant will be described in more detail below.

  A sixth variant of the capsule 1 according to the invention is characterized in that the surface portion or portions 8, 8 'of the breaking means 4 have a rigid element 13, protruding in the direction of the deformable membrane 2 and having a surface of a useful overall support 14 capable of transmitting an external mechanical force exerted on said deformable membrane 2 by the user which is sufficient to cause the pivoting of at least one surface portion 8, 8 'and a rupture of the lid 3 releasing an effective amount of S substance (s) into the contents of the container R on which said capsule 1 will be mounted.

  A non-limiting example corresponding to this type of variant has been shown in FIGS. 10 to 13.

  In order to facilitate the transfer of energy necessary for the rupture of the lid 3, the capsule 1 is preferably characterized in that the rigid element 13 has a bearing surface 14 which is useful, at least over a portion, substantially the shape of said deformable membrane 2, preferably the shape of the apex or a portion of the apex of the latter.

  Even more preferably, the rigid element 13 is made in the form of a semi-circular portion of vertical or substantially vertical semi-circular section, the bearing surface 14 being useful then in the form of a rectangular or substantially rectangular strip, according to what is shown in Figures 10 to 13 of the sixth embodiment given as an indication This configuration allows the user to deform the deformable membrane 2 to a level that can go from one point close to the base 18 (and facing said bearing surface 14) to a point near the top of said deformable membrane 2, the direction of the applied force then being substantially vertical and more convenient to exercise by a finger or the thumb of the consumer.

  A seventh embodiment provides that the intermediate part 6, provided between said deformable membrane 2 and said lid 3, is made in the form of a peripheral ring 7 on which is supported locally, via a portion hinge 9, an arched element 15 substantially conforming and at least locally the shape of the deformable membrane 2 in its initial state and whose free end 16 is formed in the form of at least one protruding element 12 or directed pointed towards the cover 3, a useful support surface 14 is provided on said arcuate element 15 which is capable of transmitting an external mechanical force exerted on said deformable membrane 2 by the user which is sufficient to cause the tilting of the protruding elements 12 end to obtain a rupture of the lid 3 releasing an effective amount of substance (s) S in the contents of the container R. This solution is illust in Figures 14-17.

  Particularly advantageously, the bearing surface 14 provided on the arched element 15 has on its inner face facing the lid 3, a vertical wall portion 17 or substantially vertical also directed towards the lid 3, a surface auxiliary support 14 'assists the transmission of the external mechanical force exerted on said deformable membrane 2 by the user to cause said rupture of the lid 3.

  According to another feature, the peripheral ring 7 and the one or more surface portions 8, 8 'and / or the one or more hinge portions 9 and / or the arcuate member 15 are made in one piece, preferably by injection of a synthetic material.

  Finally, it is also possible, if necessary, to provide the cover 3 provided in the capsules 1 with different embodiments of the first variant (FIGS. 1 and 2) in addition to at least one point or a break line. preferential, for example in the form of a pre-cut 5, in order to further facilitate, in combination with the aforementioned breaking means 4, the rupture of said seal 3.

  One or more grooves can thus be provided where the thickness of the lid 3 has been voluntarily reduced, such as by laser ablation or a similar method or the like.

  With regard to the assembly of the various constituent parts of the capsule, a first solution consists in ensuring that the cap 3 is fixed directly on the deformable membrane 2, preferably at their common circular periphery where said operculum 3 and said deformable membrane 2 contact each other in overlapping manner. - 13

  This first possibility is exemplified by FIGS. 1, 18, 19 and 22. In the embodiment illustrated in FIG. 22, for example, the arched element 15 and the ring 7 are made in a single piece in the form a single piece which can be inserted freely (without welding) into the hollow formed by the deformable membrane 2 during the manufacture of the capsule 1. The cap 3 is then directly welded to the corresponding peripheral portion of said deformable membrane 2, the arched element 15 being trapped between them without being fixed there. The manufacturing process of the capsule 1 according to this embodiment 10 is therefore advantageously simplified.

  According to a second possibility, the cover 3 is fixed directly on the lower face 6 'of the intermediate piece 6, in particular on the lower face 6' of the periphery of the ring 7 forming said intermediate piece 6, which then excludes direct contact between said lid 3 and the deformable membrane 2 (see FIGS. 3 to 17, 20 and 21).

  In the embodiment illustrated in FIG. 17, for example, the arched element 15 and the ring 7 are also made in one piece in the form of a single piece which is however fixed, for example, by welding on the operculum 3, the deformable membrane 2 itself being fixed or welded to a corresponding peripheral portion of said ring 7, the arched element 15 then being trapped between them by being fixed thereto.

  Advantageously, the cover 3 is fixed by circular welding, circular thermocontact or by any similar method on the deformable membrane 2 or the lower face 6 'of the intermediate part 6.

  The subject of the present invention is also a stopper for a neck or neck receptacle intended for the dispensing of liquids or pasty products, in particular for a bottle of mineral water, characterized in that it consists essentially of a base plate 18 intended to to be fixed on said container R and closing said container R by means of a capsule 1 according to the invention reported in a sealed manner on said base 18, the deformable membrane 2 of said capsule 1 itself being covered by a hood 19, the lower base of said capsule 1 being formed by the piercable cap 3, a sealed effective volume V filled with at least one substance S intended for to be added to the contents of the container R before consumption being thus defined between the deformable membrane 14 and said lid 3 of said capsule 1, an effective amount substance (S) being released into the contents of the container R upon rupture of the lid 3 due to a sufficient deformation of the deformable membrane 2.

  The non-limiting examples of plugs capable of being equipped with a capsule according to the invention are shown in FIGS. 18 to 22.

  Advantageously and as can be seen in Figures 18 and 19, the plug according to the invention is characterized in that the base 18 is formed as a part consisting of a cylindrical portion 21 for be fixed on the neck or the neck G of the container R provided, at its upper end, with a flat annular portion 22 forming an internal circular shoulder 23 delimiting an opening 24 of said container R, the lid 3 resting or being fixed on the upper face 22 'of said flat annular portion 22 facing the capsule 1.

  The base 18 may be made of a molded part, for example by injection, and will preferably be made of plastic.

  The base 18 makes it possible to fix the cap on the container R and at the same time provides the base for the deformable membrane 2 and the base part 20 of the rigid protective cover 19 covering said deformable membrane 2.

  As can be seen in FIGS. 18 to 22, the stopper according to the invention is further characterized in that the lower face 22 "of the flat annular portion 22 has a vertical recess 25 in the form of an annular skirt designed to collaborate with the inner face of the neck of the container R and the cylindrical portion 21 for fixing said cap on the latter.

  Advantageously, the plug according to the invention is further characterized in that the upper face 22 'of the flat annular portion 22 is provided with an annular rim 26 at least slightly deformable forming, after mounting the capsule 1 in said plug, an annular groove 27 with said flat annular portion 22 trapping the peripheral portion of the capsule 1, at the level of the cap 3 and the deformable membrane 2 and, if appropriate, the intermediate piece 6.

  In this way, it becomes possible to perfectly seal said deformable membrane 2 and to ensure the upper tightness of the sealed volume V. To this end, the annular flange 26 is folded towards the flat annular portion 22 of the base 18 during assembly of said deformable membrane 2. This crimping of the deformable membrane 2 can be further reinforced by the flat annular portion 22 of the base part 20 when it is mounted on the base 18 by compressing the latter as explained below.

  Preferably, the plug according to the invention is therefore further characterized in that the cylindrical portion 21 intended to be fixed on the neck or the neck G of the container R has on its external lateral circular wall means 28 intended to cooperate with complementary means 29 located on the base part 20 to ensure the attachment of the base part 20 to the base 18.

  These means can be all the conventional mechanical means of attachment.

  By way of nonlimiting illustrative example, the means 28 and 15 complementary means 29 are made, as suggested schematically in FIGS. 18 to 22, by "female" elements such as notches or grooves cooperating with "male" elements. as, for example, lugs or beads, etc. Also, advantageously, the plug according to the invention is characterized in that the base part 20 comprises a cylindrical sleeve 30 intended to be fixed on the base 18 and provided, at its upper end, with a flat annular portion 31 forming an inner circular rim 32 intended to bear, preferably by compressing, on the annular flange 26 which traps the peripheral portion of the capsule 1, at the level of the lid 3 and the membrane deformable 2 and, if appropriate, the intermediate piece 6.

  As explained above, this measure further advantageously reinforces the upper seal between the deformable membrane 2 and the base 18 of the plug.

  The plug according to the invention can be fixed on the neck of the container R by any usual means. Preferably, said cap is screwed onto the neck of said container R. In the latter case, it can be provided as shown in FIGS. 18 to 22, that the cylindrical portion 21 is made in the form of a cylindrical sleeve provided with an internal thread 21 'for screwing on the external thread of the neck or neck G threaded container R. - 16 In this way, the plug according to the present invention can be mounted on any container with a standard thread.

  According to another characteristic, the base part 20 has a first opening and closing means 33 intended to cooperate by snap-fitting by elastic deformation with a second corresponding means 34 located on the protective cover 19.

  In general, any device of the male-female or similar type can be adapted to the present plug in order to guarantee a reliable and easily unlockable closure of the protective cover 19.

  According to a first variant, the base part 20 has a push button provided with a first hook intended to cooperate with a corresponding second hook located on the protective cover 19.

  Thus, it is sufficient to press, for example with the thumb, said push button so that the two aforementioned hooks are detached, causing the opening of said protective cover 19 and access to the deformable membrane 2.

  According to another variant, the base part 20 has a push button provided with a recess for cooperating with a corresponding pin located on the protective cover 19.

  In order to allow the pivoting of the protective cover 19 during the opening and the retention of the pivoted part, it is advantageously provided that the protective cover 19 is connected to the base part 20 by at least one cover hinge 35.

  Alternatively, provision can be made for the cover 19 not to be permanently fixed to the base part 20 but to rest only on the latter (for example by being engaged by elastic deformation) and that it be permanently removed. when the use or consumption of the contents of the container R. In fact, the protective cover 19 is intended primarily to protect the deformable membrane 2 from any involuntary external aggression, for example during handling operations, storage and transporting the plugged containers R which could accidentally deform or damage it and break the tightness of the volume V. In a particularly simple and economical embodiment, the protective cover 19 is made in one piece with the basic piece 20. - 17

  According to another feature, the lower end of the base 18 remote from the outlet of the neck or neck G of the container R is provided with a safety ring 36.

  It makes it possible to ensure that the stopper has never been unscrewed from the neck or neck of the container R. Furthermore, the stopper according to the invention is further characterized in that it comprises, in addition, at least one dispensing device. inviolability at a means participating in the locking of the protective cover 19 in the closed position.

  Such a means may for example be made in the form of a ring or a circular band of film made of a thermoformed thermoplastic material that marries and covers, before the first use, said locking means of the protective cover. This band is torn off during the first use, for example, by means facilitating this removal such as a pre-cut portion (in dotted lines), a tear-off notch, an opening thread, etc. and thus serves as a witness opening the plug in question.

  According to another advantageous characteristic, the protective cover 19 and the deformable membrane 2 are made of one or more translucent materials, preferably transparent.

  Thus, it is possible for the user to check the presence of the substance S before use, for example the presence of a tablet such as a specific drug to be dissolved in the contents of the container R before ingestion. It also allows, in the case where transparent materials are used, to control the nature of the substance S, for example by means of a color or shape code. It is thus possible to imagine a substance S colored according to the nature of its taste which can be added to a beverage having no or relatively little taste or a taste to be modified, either reinforced or on the contrary attenuated or even masked.

  By way of non-limiting example, the substance S can be a powder, a tablet or a colored syrup intended to be dissolved in mineral water, each color corresponding to a taste or another predefined characteristic (yellow = lemon, red = apple, green = lemon35 green, mandarin orange or orange, brown = chocolate, blue = menthol, black = cola ... - 18

  Finally, the transparent embodiment also makes it possible to increase the aesthetic and playful appearance of the cap according to the invention.

  In the most general manner, the substance or substances S can be any food substance or not (whatever its state: solid, liquid, gaseous, pasty, etc.) or a mixture of substances that may be desired add to the contents of the container R, said content can also be any food content or not, also regardless of its physical state.

  Preferably, the substance or substances S are solids or liquids and the contents of the container R is a more or less viscous liquid, preferably water and even more preferably mineral water.

  Preferably, the substance or substances S and the contents of the container R are of food type, that is to say non-toxic to humans or animals.

  Although the non-limiting example of the present disclosure is given for a solid substance S and a content of the liquid container R, it goes without saying that a person skilled in the art will be able to adapt the latter to other cases not explicitly described here. providing for the customary arrangements with regard to the nature of the materials used, the dimensions of the different rooms ...

  The term "added" to said substance or substances should also be understood to include the pure and simple addition, that is, the simple fact of adding said one or more S (eg insoluble) substances to the contents of the container. R, but also their physical mixture (assisted or not) to form a stable mixture, a suspension, an emulsion, etc., their partial or complete dissolution in said content, and their chemical mixture (resulting in one or more chemical reactions).

  Advantageously, the substance or substances S comprise at least one substance sensitive to the contents of the container R with which the capsule 1 is intended to collaborate and not to be added thereto for a short time or just before consumption.

  Non-limiting examples of such substance S are medical preparations in which the active compound is very fragile and must be put in its last minute form, the mixtures physically or chemically unstable over time ( immiscible, perishable goods), etc. Thus, according to another characteristic, the capsule 1 according to the invention is characterized in that the substance or substances S comprise at least one drug.

  According to another characteristic, the capsule 1 according to the invention is characterized in that the substance or substances S comprise at least one oral cosmetic agent, for example a solution of oral collagen.

  As mentioned above, the substance or substances S are preferably of a food nature.

  Advantageously, the substance or substances S are chosen from the group formed by: dyes, flavors, preserving agents, sweetening agents, thickening agents, stabilizers, nutraceuticals, nutritional or dietary supplements or any composition obtained from at least two of these ingredients.

  By food is meant any food considered particularly beneficial to health (dairy products or cereal-based, fiber ....) Finally, the capsule 1 according to the invention is further characterized in that the substance or substances S comprise at least one solid substance, optionally reduced in the form of powder or granules.

  As shown in Figures 1 to 4, the capsule 1 (or the plug) according to the invention has a rounded outer shape 25 substantially half-sphere shape, possibly slightly flattened.

  Thanks to these ergonomic rounded shapes, the handling of the containers thus plugged (grip, transport ...), as well as their aesthetic appearance are reinforced and the risk of injury, especially in children, reduced.

  According to one particularly advantageous variant, in particular for a capsule 1 according to the first embodiment (FIGS. 1 and 2) to which it is particularly well adapted, the internal circular shoulder 23 delimiting an opening 24 of said plugged container R is provided on a portion of its inner periphery of at least one tooth-shaped element 37, intended to facilitate the rupture of the pierceable cap 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1 (see FIG. 18). - 20

  Alternatively, it can be provided for this type of capsule 1, that the annular vertical recess 25 (of the base 18) is provided with a pair of parallel arms 38, 38 'extending in a plane parallel to the surface of the 3 and forming on the inner periphery of said vertical recess 25 at points 39, 39 'diametrically opposed, said arms 38, 38' being preferably interconnected by a pontoon 40 passing through the center of the opening 24 , said arms 38, 38 'each having, at their ends, at least one projecting element in the form of a tip 41, 41' or the like directed towards the surface of the cap 10 3 and intended to facilitate the rupture said pierceable lid 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1.

  This particular embodiment is shown in Figures 23 to 26 which have been simplified for clarity with respect to Figures 18 to 21.

  During injection molding of the part in question, the pontoon 40 may be used as the injection site I for the plastics material (see Fig. 26).

  During a sufficient deformation of the deformable membrane 2 with or without assistance including the substance or substances S contained in the sealed volume V of the capsule 1, the lid 3 which is above and at a safety distance sufficient points 41, 41 '(to prevent any accidental breakage) is pushed downwards towards the latter which pierce it or cause the initiation of the break at a predetermined pre-existing point or line of rupture, so to release a sufficient quantity of substance (s) S into said container R. Finally, the present invention also relates to a container R neck or neck for dispensing liquids or pasty products, in particular mineral water, characterized in that it comprises a capsule 1 according to the present invention.

  Advantageously, said container R is characterized in that said capsule 1 is mounted in a stopper according to the present invention.

  To pour or drink directly from the neck or the neck G of the container R the mixture resulting from the mixing of the substance or substances S with the contents of the container R, it suffices to completely unscrew the stopper to allow the passage of said mixture through the opening 24 of the container R. This embodiment is economical because it does not require addition of room to pour the mixture. In addition, the cap can be screwed and unscrewed at will without altering the tightness of the container R, which also keeps said mixture in the container R, while ensuring protection vis-à-vis the outside , because the deformable membrane 2 is impermeable, even after deformation. It is also possible to provide an element such as a valve at the base 18 to allow the evacuation of any gases formed during the mixing of the substance S with the container of the container R and accumulating in the container R ( for example CO2 for effervescent tablets), and thus avoid a risk of overpressure.

  An access or a second plug may also be provided on the side surface of the container R to allow the distribution of said mixture. This access or second plug may further present a degassing means. This variant embodiment is more complicated to implement, and therefore more expensive. In addition, it requires the addition of a part, which causes a rupture of the symmetry of the container R and has the effect of complicating its storage and handling.

  Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications are possible, especially from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of the invention. - 22
