Definitions

  • the subject of the present invention is a can or similar container comprising a pouring neck which can be closed off by a stopper which is fixed on said neck and which, inside, is provided with a destruction device, permanently installed, for a sealing member fixed in leaktight manner to the end of the neck of a bottle, this device comprising at least one passage opening for the liquid contained in the bottle, a guide bore for the neck of the bottle and a cutting member which is provided at the passage opening.
  • Such a container is known from US Pat. No. 3,270,524.
  • This container is associated with a bottle of very small dimensions and at the same time serving as a stopper.
  • the destruction device hung on the edge of the frustoconical mouth flared outwards and disposed inside this mouth has near its small lower base an opening and a vertical cutting knife provided on the edge of this opening.
  • This structure requires an oblique arrangement of the closure member of the bottle and a very precise positioning of the bottle relative to the container in order to avoid inadvertent drilling of the closure member of the bottle.
  • the area cut out in the closure member of the bottle is surrounded without much lateral play by the destruction device, so that a rapid flow of the liquid contained in the bottle is not guaranteed.
  • both the mouth of the container and that of the bottle have a frustoconical shape in which that of the container flares upwards and that of the bottle tapers towards the opening of the inverted bottle, the two mouths fitting together. 'one in the other.
  • the rotary cutting movement of the bottle relative to the container is therefore greatly hampered and can lead to jamming of the bottle.
  • the destruction device comprises a cylindrical cutting member which penetrates without lateral play in the neck of the bottle screwing onto the upper part of the destruction device and pushes the shutter member of the bottle into the neck of the latter. This ; this shutter member frequently gets stuck in the cylindrical cutting member and at least partially blocks the flow opening defined by the inner face of the cylindrical cutting member. Furthermore, the upper part of the destruction device, part comprising the cutting member is separated from the container when the bottle is removed from the neck of the container, so that the latter cannot be reused under the initial conditions.
  • cans or receptacles comprising a pouring neck which can be closed off by a plug which is fixed to said neck, preferably by screwing.
  • Such cans with a capacity, for example, of one liter, are often made of a thermoplastic material and are intended to contain a detergent or another cleaning liquid such as bleach.
  • These cans contain a low concentration cleaning liquid and are used, after consumption of their content, to mix a certain amount of water with a dose of concentrated detergent generally contained in soft plastic cartons whose handling is difficult, otherwise dangerous from their opening until their complete emptying.
  • a bleach solution for household use we mix, for example, a dose of bleach of 250 milliliters concentrated at 48 ° chlorometric with 750 milliliters of water to obtain a liter of bleach at 12 ° chlorometric, the concentration of which is suitable for household use.
  • the aim of the present invention is to eliminate the aforementioned drawbacks and to propose a container making it possible to safely pour the concentrated dose contained in a bottle into the container.
  • the destruction device comprises, on the one hand, a cylindrical wall whose inner face delimits the guide bore and, on the other hand, at its upper end, an annular stop that can receive the support of an enlarged frustoconical part of a bottle, stop whose internal face is also frustoconical and is connected, by its lower edge, to the internal face of said cylindrical wall and that the cutting member is provided at the end bottom of the cylindrical wall and projects towards the axis of the guide bore.
  • the destruction device comprises, on the one hand, a cylindrical wall whose inner face delimits a guide bore and, on the other hand, at its upper end, an annular stop that can receive the support of an enlarged frustoconical part of a bottle, a stop whose internal face is also frustoconical and is connected, by its lower edge, to the internal face of said cylindrical wall and that the cutting member is in the form of cone or hollow pyramid which is arranged coaxially inside the guide bore and which comprises a point directed upwards, an openworked intermediate part and a continuous lower part which, at its base, is connected to the end bottom of the cylindrical wall.
  • the closure member of the bottle or similar container containing the concentrated dose is destroyed without difficulty and without jamming the bottle after its introduction. inside the container, so that the concentrated liquid flows quickly and through a large passage section in the container.
  • at least the neck of the bottle has a certain rigidity, but it is also possible to use cartons whose very thin walls only hold when said cartons are completely filled with a liquid or a paste and one end of which ends in a sort of neck which is introduced into the neck of the container where it can be destroyed, for example pierced, by the device for destroying said container.
  • the invention also relates to a set of containers consisting, on the one hand, of a can of the aforementioned type provided in its neck with a destruction device and, on the other hand, of a bottle provided with a neck which is sealed by a shutter member and which has dimensions such that its shutter member can be introduced into the destruction device and presented in front of the cutting member thereof.
  • This set of containers is characterized in that the neck of the bottle has an outside diameter of a few millimeters less than the inside diameter of the cylindrical wall of the destruction device and than at the point of attachment of the closure member to the edge of the neck of the bottle, said sealing member or said neck has an annular guide bead which engages without significant lateral play in the guide bore of the destruction device.
  • This adaptation of the neck of the bottle and its closure member to the destruction device provided in the neck of the container provides increased security when the bottle is opened and its liquid content is transferred into the container since said content of the bottle does not can flow elsewhere than in said container from the opening of the bottle, the part of the bottle which rests on the neck of the container forming a kind of protective screen against liquid projections which could occur during the opening of the container. bottle.
