Definitions

  • the present invention relates to a safety device for equipping a bottle, in particular a bottle which is not originally equipped with a safety stopper.
  • the object of the invention is to equip such bottles with a safety device preventing access to the product contained in the bottle to children.
  • the invention provides a safety device for equipping a bottle, in particular a bottle originally equipped with a safety cap, characterized in that it is formed by a plastic cap of general shape. cylindrical, closed at one end, having an opening for the neck of the bottle at the other end and consisting of two parts which can be articulated relative to each other along a generatrix of the cylinder, and in that on the side opposite the joint, the overcap has a locking system requiring the combination of two simultaneous actions to achieve unlocking.
  • this device can be adapted to a bottle neck. Sealing is ensured by the bottle cap and the safety function is ensured by the cap.
  • the cylindrical shape is adapted to the neck of a bottle. This cylinder is preferably of circular section, but may also have a polygonal, or even arbitrary, section.
  • the synthetic material used for the manufacture of this device is preferably resistant to solvents.
  • the cap can easily adapt to the neck of a bottle.
  • the stops of the elastic blade and of the first articulated part are in contact and prevent the opening of the overcap by simple pivoting of the two constituent parts of the overcap around the articulation axis. It is therefore necessary that one stop escapes the other.
  • the stop of the first part of the cap being fixed, it is necessary to move the other stop by acting on the elastic blade. However, it abuts against the protuberance.
  • the elastic tab is formed by a part of the cylindrical wall of the overcap situated between two slots formed perpendicular to the joint and extending to the junction plane of the two parts of the cap.
  • the latter can be provided with a push button.
  • the invention proposes to chamfer a surface of each stopper, so that the chamfered surfaces come into contact with one another when the overcap is closed.
  • a preferred embodiment of the overcap according to the invention is characterized in that the elastic tab has two protrusions extending towards the outside of the overcap, in that two stops are formed on the cylindrical wall of the first articulated part of the overcap , one on each side of the elastic tab, and in that the second part of the overcap comprises two parallel elastic blades, each having on its face opposite to the other blade, a stop cooperating with a stop of the first part of the overcap, each elastic blade being placed in the closed position between a protuberance of the elastic tab and a stop of the first articulated part.
  • the two parallel elastic blades then form a clamp which is easy to pinch, to deform the elastic blades, by gripping it between the thumb and forefinger with one hand.
  • the operator's other hand thus acts on the elastic tab and thus allows the opening of the overcap.
  • the articulation of the two parts of the overcap is made by means of a hinge produced by thinning of material.
  • the overcap has, near the edge of its open end and on its inner face, a peripheral groove intended to receive two half-rings of external diameter substantially equal to the diameter of the bottom of the groove and outside diameter adapted to the neck of the bottle.
  • Figure 1 is a perspective view of an overcap according to the invention in the closed position on a bottle.
  • FIG. 2 is a perspective view of the same cap in the open position
  • Figure 3 is a front view, partially in section, on an enlarged scale of this closed cap.
  • Figure 4 is a sectional view along the linen IV-IV of Figure 3.
  • Figure 5 is a perspective view of a ring to adapt the overcap to a bottle.
  • An overcap 1 according to the invention is intended to cover the neck of a closed bottle 2, as shown in FIG. 1. It has a safety locking system, in order to prevent children from accessing the contents of bottle 2.
  • This overcap is especially intended for bottles containing a dangerous and / or toxic product and not provided with a safety cap. This happens in particular when such products are transferred from a large container to a smaller bottle, or even when such products must be diluted. The bottle which is then chosen is not generally intended to contain a dangerous and / or toxic product and therefore is not provided with a safety cap.
  • the overcap 1 shown in the drawing is made of synthetic material resistant to solvents, such as for example polypropylene. It is generally cylindrical in shape with a circular section. The top of this cylinder is closed by a bottom 3 and its other end has an opening intended to receive the neck of the bottle 2.
  • Two parts 4,5 in the shape of a half-cylinder constitute the overcap 1. They are articulated with respect to each other along a generator of the cylinder. This articulation is produced by a thinning so as to form a hinge.
  • the safety locking system Opposite the joint is the safety locking system.
  • a part of the constituent elements of this locking system are integral with a first articulated part 4 of the overcap, the others are integral with the second part 5.
  • the elastic tab 6 is formed by a part of the wall of the first articulated part 4.
  • the latter has two slots 8 which extend over approximately 45 °, in a plane perpendicular to the generatrices of the cylinder, and which join the junction plane of the two articulated parts 4.5.
  • the area between the two slots 8 forms the tab 6.
  • the elastic tab 6 also has two ribs 10 projecting outwards from the overcap. These ribs are in a plane perpendicular to the articulation of the two articulated parts 4, 5.
  • the two fixed stops 7 are placed on either side of the tab 6, near the junction plane of the two articulated parts 4,5. They are chamfered on the side of the elastic tab and the junction plane.
  • the second articulated part 5 of the overcap 1 is provided with two elastic blades 11.
  • Each elastic blade 11 is located in a plane perpendicular to the axis of articulation. In the closed position, each elastic blade 11 is placed between a rib 10 of the elastic tab 6 and a fixed stop 7. The elastic blades 11 are in contact with the ribs 10.
  • Each elastic blade 11 carries a stop 12. In the closed position, this stop 12 rests against a fixed stop 7.
  • the face of each stop 12, opposite to a fixed stop 7 in the closed position, is chamfered.
  • this overcap can adapt to the largest possible number of bottles, provision is made to be able to vary the diameter of the opening opposite the bottom 3.
  • the inner edge opposite the bottom 3 is equipped with a groove 13.
  • Two half-rings 14 (shown in Figure 5) are intended to be housed in this groove. They comprise a fixing stud 15 which is placed with clamping in an opening made at the bottom of the groove 13.
  • the outside diameter of the half-rings 14 is substantially equal to the diameter of the bottom of the groove 13 and their inside diameter is substantially equal to that of the neck of the bottle 2 intended to be equipped with the overcap.
