Definitions

  • the present invention relates to a container provided with a pouring member closed by a stopper, such as a bottle or flask, preferably of plastic material, for single use and intended to contain a unit dose of a liquid dangerous for health, such than a caustic liquid.
  • a stopper such as a bottle or flask, preferably of plastic material
  • cleaning liquids such as bleach are caustic products which are all the more dangerous as they are very concentrated, this concentration serving to allow them to be contained in small volume packaging.
  • these concentrated cleaning products should not be stored in open containers and the entire dose contained in the closed container should be used up in one go.
  • you must use a concentrated dose of bleach of 250 ml at 48 chlorometric degrees with 750 ml of water to obtain a liter of bleach at 12 chlorometric degrees whose concentration is suitable for household use.
  • these unit doses of concentrated caustic liquid product have been contained in soft plastic bottles or flasks, the handling of which is difficult if not dangerous from their opening until their complete emptying.
  • the present invention eliminates the aforementioned drawbacks and aims at a container of the type indicated at the start which has good maneuverability and encourages the user to consume at once the entire dose of liquid contained in the container.
  • the container comprises a rigid neck as a pouring member, an at least semi-rigid bottom and at least semi-rigid side walls, as the parts of the wall bottom are inclined with respect to the axis of the neck and of the container at an angle sufficient for said container to be able to hold in the upright position, only the cap having, in a manner known per se, a closure wall extended towards the bottom by side skirt, is itself destructible and must be destroyed for the opening of the container and is tightly fixed on the free edge of the neck through the rear or lower end of the side skirt, lower end fixed permanently on said edge of the neck.
  • the side skirt has a closed annular band provided with a gripping tab and connected to the lower part and to the upper part of the skirt or to the sealing wall by annular zones of weakness allowing the destruction of the plug and the tearing of the skirt by traction on the gripping tab.
  • the container or bottle can also be handled with all the security required during emptying and the fact that the cap is destroyed it cannot be reused after the opening of the container and also because the said container does not stand upright , the user is encouraged to use the entire contents of the container and discard it immediately after emptying.
  • the unit dose container 1 such as a small bottle or a vial is preferably made of a plastic material, for example, using a molding operation by extrusion blow molding or injection blow molding, this plastic material being impermeable to air.
  • the container 1 comprises as a pouring member a neck 2 which is rigid and which flares backwards, that is to say towards the bottom, to be connected to the side walls 3 which are at least semi rigid, if not rigid and which terminate in the bottom 4 which, for its part, is preferably rigid and at least semi-rigid and comprises bottom parts 4a, 4b etc.
  • the generatrices of the side walls 3 can be parallel to the axis 5 of the neck 2 and of the bottle 1, but with a view to inciting the user to keep no residue of the contents of the container 1 after the opening of the latter, it is advantageous to also give the side walls a curved or domed shape 3a (see broken lines in Figure 1). This eliminates even the stable position of the container 1 when it rests on flat side faces 3 (see FIG. 2) which, in certain cases, are more advantageous, in particular with a view to reducing the transport volume occupied by several containers.
  • the cross section of the container 1 can be circular, oval, etc. or register in a triangle, a rectangle, a square or any other polygon. It is also advantageous to provide a curved bottom 4 comprising several curved bottom parts 4a, 4b, 4c, 4d which converge towards the axis 5. At each point of surface, for example 6, of the convex bottom 4, it is possible to associate a tangent 7 which is situated in a radial plane comprising the axis 5 and which includes with said axis 5 an angle A or ⁇ preferably between 15 ° and 75 ° or between 105 ° and 165 °, these angles being in any case different from 90 ° and sufficient to prevent the container 1 from being able to stand.
  • the free end of the rigid neck 2 is closed by a destructible plug 8 which has the particularity of being permanently fixed to the edge 2a of the neck 2.
  • the destructible plug 8 which has a cross section similar to that of the neck 2, by example circular, oval, or polygonal, comprises a closure wall 8a which extend transversely to the axis 5, and can be slightly curved either outwardly, or preferably inwardly of the plug and which is extended downwards (that is to say towards the bottom 4) by a lateral skirt 8b, the lower or rear end 8c of which is shaped as a bead provided with a coaxial annular groove or groove 8d, the lateral flanks 8e of which cover the edge 2a of the neck 2.
  • the stopper 8 can also be made of a plastic material and the tight fixing of said stopper 8 on the edge 2a of the neck 2 can be done by gluing or by welding when the bottle and the stopper are made of thermoplastic material .
  • annular grooves 9, 10 From the outer face of the side skirt 8 are formed therein two annular grooves 9, 10 parallel to each other and perpendicular to the axis 5 of the neck 2. These annular grooves 9, 10 are located opposite zones annular weakening 11, 12 whose thickness is less than the normal thickness of the wall of the side skirt 8 and can be torn.
  • the annular grooves 9, 10 and the weakening zones 11, 12 define in the skirt 8 an annular tear strip 13 which, by means of a radial spacer 14, is connected to a gripping tongue 15 extending, over a short distance, parallel to the strip 13. As can be seen in FIG.
  • the tear strip 13 present in the immediate vicinity of the spacer 14, in its part covered by the tongue of gripping 15, a thinning 16 facilitating the start of the tearing off of the strip part secured to the spacer 14.
  • the plug 8 being made of a plastic material and molded, all the constituent elements of said plug 8 are in one piece.
  • the thickness of the skirt and the axial width or height of the tear strip 13 are such that the tensile strength of said strip 13 is sufficient to ensure the tear of the skirt 8b at the locations of the weakening zones 11, 12 , that is to say grooves 9, 10 and to prevent both the rupture of said strip 13.
  • the opening of the container 1 is extremely simple and safe and must be done by destroying the plug 8. It suffices to pull the gripping tab 15 so as to rotate it around the neck 2 to from its free end in the direction of the spacer 14. It will be seen that the tear strip 13 will separate completely from the lower part of the skirt 8, the lower part comprising the bead 8c and fixed permanently to the neck 2, and that over a short length, it will remain attached to the upper part of the skirt 8 or to the closure wall 8a, which avoids any contact of the fingers with the latter.
  • the various embodiments described above can undergo a number of modifications without departing from the protective framework defined by the appended claims. It is understood in particular that the structure of the stopper used in combination with the container may be different from that described above, provided that the skirt of the stopper is permanently fixed to the neck of the container and includes a tear strip which, once removed, destroys the cap and at the same time opens the container.
  • the container described above can be provided with a stopper as described in the patent application entitled "Destructible stopper for single use and bottle provided with such a stopper" and deposited on the same day in the name of the holder of this patent application. .
  • the annular grooves 9, 10 and the corresponding weakening zones 11, 12 are not necessarily parallel to each other and perpendicular to the axis 5 of the neck 2. These grooves 9, 10 can also intersect or be more or less inclined to each other without intersecting, the gripping tab 15 being advantageously attached to the widest part of the tear strip delimited by said grooves.
  • the bottom 4 of the container 1 it may be advantageous to provide for the grouped transport of several, containers 1 in cardboard boxes, a means for keeping the containers upright.
  • a restricted placement 16 which comprises a support shoulder 17 of small width and perpendicular to the axis 5 and a side wall 18 set back from the width of the support shoulder 17 relative to the side walls 3 and of low height.
  • the containers 1 can engage by their constriction 16 in the cells of corresponding shape of a honeycomb support plate placed in the cardboard box.
