Definitions

  • the present invention relates to a cap for a neck or neck container for dispensing liquids or pasty products, in particular for mineral water bottle and the corresponding cap and container, said cap containing a capsule mounted therein.
  • the stopper 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 ).
  • plastics for example PET
  • 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 ).
  • a number of corks having compartments containing a substance, especially 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 the preparation of energy drinks or baby bottles.
  • a plug according to the preamble of claim 1 is known from US 2002/0066680 A1 .
  • 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, remove the membrane or tongue closing said tank 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 a such type of plug 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 the latter.
  • Another type of plug has a capsule or reservoir releasing a solid substance in the form of a tablet via a pressure exerted by a finger of the user on said capsule.
  • 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.
  • 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 .
  • the user can remove the lid, while the cap is fixed on the container. In both cases, many tedious steps are needed again to release the substance.
  • another disadvantage lies in the fact that the operculum of the capsule to release the substance works well only when the substance is in the form of tablets or pellets.
  • 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 serving as sealing member.
  • the lower lid is torn by the tablet when the user exerts pressure on the upper membrane.

Indeed, when the rigidity of the lid is too low, it breaks during the handling steps, and the substance accidentally mixes with the contents of the container.
  • 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.
  • this pressure transmitted to the operculum through the substance should be identical, regardless of the form and constitution of the substance.
  • 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 present invention aims at overcoming at least some of the disadvantages of known caps and caps is intended to provide a stopper to minimize the risk of accidental rupture of the lid to isolate the substance of 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.
  • 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 force exerted by the user able to break the seal seal.

  • This bridge 10 ' also imposes on the user, when he wishes to tear the lid 3, to apply a pressure or force on the arched element 15 which is sufficient to break said bridge 10' and which, at the same time time and because of its high intensity and its abrupt application, makes it possible to break or cut more clearly or more certainly of the operculum 3, with respect to a progressive rupture by application of a force that grows as and when measuring, thus releasing all the substance S contained in the capsule 1.

  • the capsule 1, or the plug provided with such a capsule 1 have a rounded outer shape substantially half-sphere shape, possibly slightly flattened.
  • the inner circular shoulder 23 delimiting an opening 24 of said plugged container is provided on a part of its inner periphery with at least one tooth-shaped element intended to facilitate the rupture of the pierceable lid 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1.
  • annular vertical recess (of the base 18) provided with a pair of parallel arms 38, 38 'extending in a plane parallel to the surface of the cover 3 and originating on the periphery can be provided. internal 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 lid 3 and intended to facilitate the breaking of said pierceable lid 3 during a sufficient deformation of the deformable membrane 2 of the capsule 1.
  • the operculum 3 which is above and at a distance of sufficient security of the tips 41, 41 '(to avoid any accidental breakage) is pushed downwards towards the latter which pierce it or cause the beginning of the break at a pre-existing point or line of preferential rupture, so as to release a sufficient quantity of substance (s) S into said container.

  • said capsule 1 is mounted in a plug according to the present invention.
  • the mixture resulting from the mixture of the substance or substances S with the contents of the container simply unscrew the cap completely to allow the passage of said mixture through the opening 24 of the container.
  • This embodiment is economical because it does not require adding room to pour the mixture.
  • the cap can be screwed and unscrewed at will without altering the tightness of the container, which also keeps the mixture in the container, while ensuring protection vis-à-vis the outside, the fact that the deformable membrane 2 is impermeable, even after deformation.
  • An access or a second stopper can also be provided on the lateral surface of the container 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 and has the effect of complicating storage and handling.
