Definitions

  • the invention relates to the assembly of a container and a stopper, the container comprising an internally cylindrical neck, closable by means of the stopper which is formed from an externally cylindrical skirt and from an externally planar head. or approximately flat, the skirt being intended to be introduced with a certain tightening inside the neck of the container, this neck and the stopper being made of an elastically deformable material so that a pressure exerted approximately Radially on the outer surface of the neck has the effect of ovalizing both the neck of the container and the skirt of the cap.
  • container is meant here hollow bodies such as in particular bottles, flasks, tubes and cans, which can be filled and emptied by means of uri.orifice limited by a neck or neck and closable using 'a plug.
  • the invention aims to make the above mentioned such that the container can not be opened by young children, while being particularly economical and easy to produce.
  • Such protection vis-à-vis young children is especially advantageous when the products contained in these containers are harmful to these children (pharmaceuticals, cleaning products and the like).
  • the container neck internally comprises abutment means, of continuous annular shape, which cooperate with the external lateral surface of the plug so as to oppose the insertion of the latter, beyond an axial position such that the outer surface of the cap head is then located approximately in a plane passing through the free end of the neck of the container.
  • the stopper when the stopper is pressed into the neck of the container at this limit position, it is held there by friction of its skirt against the inside surface of the neck and it then does not offer children's fingers, teeth, etc. no socket allowing its opening.
  • the skirt of the plug when sufficient pressure is exerted at any two points on the outside surface of the neck, the skirt of the plug, under the effect of the deformations which it undergoes and while resting on the stop means of the neck, is found thrust outside of it, in whole or in part; in the latter case, the plug then offers the fingers sufficient grip so that it can be grasped and extracted completely. Opening the cap therefore requires non-able gestures before a certain age, as well as a sense of observation and / or physical skills which are totally or partially lacking in young children.
  • the neck of the container the stop means of which have an annular shape and are arranged so as to act only in the direction limiting the insertion of the plug (and not in the opposite direction), is easy to manufacture.
  • the abutment means of the neck of the container are constituted by a frustoconical zone flaring outwards and cooperating with a conjugate frustoconical zone which is formed on the external surface of the stopper.
  • the conjugate frustoconical zone is formed towards the free end of the skirt of the stopper while the frustoconical zone of the neck of the container is formed at a distance from the free end of this neck.
  • the conjugate frustoconical zone is formed near the head of the stopper while the frustoconical zone of the container neck is formed near the free end of this neck.
  • the abutment means of the neck of the container are constituted by an annular rib and preferably cooperate with a conjugate frustoconical zone which is formed at the free end of the skirt of the stopper.
  • the stopper advantageously comprises, inside its skirt and at a radial distance from the latter sufficiently large to allow the ovalization of this skirt, a cylindrical wall adjoining the head of the stopper and serving as a support for a desiccant.
  • FIG. 1 represents the neck 1 of a container and the plug 2 which is adapted to this neck. If the container is a bottle, a flask, a can etc .; the neck 1 is formed by the neck of this container. If the container is a tube, the neck 1 is simply formed by the top of the tube.
  • the neck 1 is made of a flexible and elastic material. It must return to its shape more or less quickly after successive pressures and ovalizations at its mouth and be easily produced in large series and at low cost. In the current state of the art, it seems that certain qualities of plastics, well known to those skilled in the art, are most suitable.
  • the neck 1 has a cylindrical inner surface 3 while the plug 2 is formed by a skirt 4 and a head 5, flat or nearly flat.
  • the skirt 4, the external surface of which comprises a cylindrical part 6, is intended to be introduced with a certain tightening inside the neck 1 in other words, the diameter of the cylindrical part 6 of the skirt 4 is equal or very slightly greater than that of the cylindrical inner surface 3 of the neck 1 so that the plug 2, properly pressed, is held in place by friction, even when the container is overturned and stirred with its contents.
  • the cylindrical surface and part 3 and / or 6 can be either completely smooth or at least partially rough.
  • the neck 1 has internally. Abutment means, of continuous annular shape, which cooperate with the external surface of the plug 2 so as to oppose the insertion of the latter at- beyond a limit position such that the outer surface of the head 5 of the plug 2 is then located approximately in a plane P passing through the free end of the neck 1 of the container.
  • the abutment means of the neck 1 consist of a frustoconical zone 7 (FIG. 1) or 7a (FIG. 2) flaring outwards and cooperating with a conjugate frustoconical zone 8 ( Figure 1) or 8a ( Figure 2). Which is provided on the outer surface of the plug 2.
  • the frustoconical zone 8 is formed towards the free end of the skirt 4 of the plug 2 while the frustoconical zone 7 of the neck 1 is arranged at a distance such as the end of this neck 1 that, as specified above, the external surface of the head 5 is situated approximately in the plane P when the frustoconical zones 7 and 8 are in mutual contact, as shown in FIG. 1.
  • the angle at the top of the frustoconical area 7 of the skirt 4 is calculated so as to facilitate the introduction of the plug into the neck 1.
  • the angle at the top of the frustoconical area 8 of the neck is chosen to be equal to the previous one.
  • the seal is essentially ensured by applying the axial cylindrical part 6 of the plug against the axial cylindrical part 3 of the neck of the container.
  • An exaggerated untimely depression of the plug 2 is prevented by the frustoconical zone 7 of the neck on which the frustoconical zone 8 of the skirt 4 of the cap is applied.
  • the surfaces de.frottement between the cylindrical parts 3 and 6 and frustoconical 7 and 8 are sufficient to ensure that the cap 2 is kept away from any untimely opening by the contents of the container after overturning of the latter.
  • the container is opened by pinching the neck 1 at any two points on its outer surface.
  • This pinching causes the simultaneous deformations of this neck and the stopper 2. Due to its elasticity, the latter tends to resume its normal shape, by sliding on the inner wall of the neck 1, in the only direction in which it is free to move. , that is to say upwards and outwards from the neck 1, in general until complete clearance. If the parts 3, 6 and 7, 8 of the neck 1 of the stopper are rough, it may be necessary to subject the neck 1 to several successive pinches or else to grasp the stopper 2 as soon as it offers sufficient grip to the fingers, this which makes it even more difficult for an infant to open the container.
  • the conjugate frustoconical area 8a is formed near the head 5 of the plug 2 while the frustoconical area 7a of the neck 1 is formed near the free end from this pass.
  • the latter comprises, as before, a frustoconical zone 8 at its free end.
  • the cylindrical part 6 of the skirt is limited, on one side, by a recessed frustoconical zone 8 and, on the other side, by a protruding frustoconical zone 8a.
  • the angle at the center of the frustoconical stop zones 7a, 8a may be greater than in the previous case.
  • FIG. 2 has roughly the same advantages as that of FIG. 1. It can nevertheless be noted that the plug 2 of FIG. 2 is a little less easy to manufacture than that of FIG. 1 but that, by pinching of the mouth of the container, the frustoconical zone 7a of the neck 1, by pushing on the frustoconical zone 8a of the cap 2 of FIG. 2, ensures the axial displacement of the latter upward, relative to the neck 1, d 'a little more efficient in general than in the case of Figure 1.
  • the abutment means of the neck 1 of the container are constituted, not by a frustoconical zone, but by an annular rib 17 which preferably cooperates with the frustoconical zone 8 which is formed, as previously , towards the free end of the skirt 4.
  • this frustoconical zone 8 fulfills a double function: guiding the insertion and abutment at the end of the insertion of the plug 2.
  • the container or tube comprising the neck 1 is not overfilled, if its content is solid, incompressible and of the diameter of the tube (tablets), so as not to hinder the ovalization of the top of this container when uncorking.
  • their caps generally comprise, when they have such contents, inside their body and longer than the latter, a support piece for tablets, lozenges, etc. which is mounted on spiral strips, acting as springs.
  • the plugs of the device according to the invention can comprise, without any difficulty, this same part and there is then no particular precaution to be taken for filling the tube.
  • the plug 2 comprises, inside its skirt 4 and at a radial distance from the latter, a cylindrical wall 9 adjoining the head 5 and serving to support a solid and rigid desiccant block 10.
  • the cylindrical wall 9 has a shape of revolution around the axis of symmetry of the plug 2 and its skirt 4. The above radial distance, which is generally a few millimeters, is large enough not to hinder the deformation of the skirt 4 which is necessary for the ejection of the plug.
  • the cylindrical wall 9 may have an internal projection 11, continuous or discontinuous, for elastically retaining the block 10.
  • the free end of the wall 9 is at the same level as the free end of the skirt 4.
  • the quantity of desiccant contained in such a wall is insufficient, due to the reduction in diameter of the housing offered to the desiccant compared to its current normal cap, nothing prevents increasing the height of the cylindrical wall 9 which, with the desiccant block 1 0 , can then serve as a "presser" for the content, as well as it has been represented in FIG. 4.
  • cylindrical wall 9 of FIG. 4 can equally well be adapted to the head 5 of the embodiments of FIGS. 1 and 2 or of similar embodiments.
