Abstract

A device for preventing the self-unscrewing of a screw cap from a container, e.g. a bottle for use in pharmacy or perfumery and typically containing a volatile liquid product. The container has a neck having formed thereon a screwthread and a projection at or below the lower end of the neck screwthread. The cap screwthread has such a length that, during screwing of the cap onto the neck, the front or lower end of the cap screwthread strikes against the projection when the inside surface of the top portion of the cap is in contact with the top end of th neck. Final screw tightening of the cap causes the front or lower end of the cap screwthread to ride over the projection so that the cap is held more securely in a tightened condition on the container neck.

Description

La présente invention concerne un dispositif pour éviter l'auto-dévissage d'un bouchon sur un flacon.The present invention relates to a device for avoiding the self-unscrewing of a stopper on a bottle.

Cet auto-dévissage résulte notamment du dépôt de liquide sur le filet de flacon lors du remplissage de ce dernier, ainsi que des vibrations auxquelles peut être soumis le flacon durant sont transport.This self-unscrewing results in particular from the deposit of liquid on the bottle thread during filling thereof, as well as vibrations to which the bottle may be subjected during transport.

On connaît déjàpar le brevet français n° 2 318 795 un flacon comportant des moyens évitant l'auto-dévissage du bouchon selon la première partie de la revendication 1. Le col du flacon présente un filet se terminant par une nervure transversale. Le bouchon comporte une saillie espacée de l'extrémité de son filet. Le blocage du bouchon est en partie assuré grâce au chevauchement de la nervure du col par la saillie du bouchon. Par ailleurs, un blocage complémentaire et le placage du bouchon contre l'extrémité du col de flacon, et donc l'étanchéité de la fermeture sont assurés par une nervure circulaire du fond de bouchon qui vient s'encliqueter dans une gorge correspondante du col de flacon.Already known from French Patent No. 2,318,795 a bottle comprising means preventing self-unscrewing of the cap according to the first part of claim 1. The neck of the bottle has a thread ending in a transverse rib. The stopper has a projection spaced from the end of its thread. The blocking of the cap is partly ensured by the overlapping of the rib of the neck by the projection of the cap. Furthermore, an additional blocking and the placing of the stopper against the end of the neck of the bottle, and therefore the sealing of the closure, are ensured by a circular rib of the stopper bottom which snaps into a corresponding groove in the neck of the stopper. bottle.

Une telle solution est peu envisageable industriellement en raison de la multiplicité des formes particulières du bouchon et du col de flacon, et du coût de réalisation correspondant.Such a solution cannot be envisaged industrially because of the multiplicity of particular forms of the stopper and of the neck of the bottle, and of the corresponding production cost.

Aussi le but de la présente invention est de proposer un dispositif pour éviter l'auto-dévissage du bouchon d'un flacon qui soit de conception très simple et donc économique.The object of the present invention is therefore to propose a device for avoiding the self-unscrewing of the stopper of a bottle which is of very simple and therefore economical design.

L'invention concerne à cet effet un dispositif pout éviter l'auto-dévissage d'un bouchon sur un flacon, le flacon comportant un col muni d'un filet extérieur destiné à coopérer avec un filet intérieur du bouchon, ledit col portant par ailleurs un plot en saillie destiné à coopérer avec l'intérieur dudit bouchon, ce plot étant espacé de l'extrémité basse dudit filet extérieur du col, dispositif caractérisé en ce que la longueur dudit filet intérieur du bouchon est telle que son extrémité bute contre ledit plot lorsque le fond dudit bouchon est à peu près au contact de l'extrémité dudit col et que ledit filet intérieur puisse passer au-delà dudit plot lorsque l'on force la rotation dudit bouchon.To this end, the invention relates to a device for avoiding the self-unscrewing of a stopper on a bottle, the bottle comprising a neck provided with an external thread intended to cooperate with an internal thread of the stopper, said neck also carrying a protruding stud intended to cooperate with the interior of said plug, this stud being spaced from the lower end of said external thread of the neck, device characterized in that the length of said inner thread of the plug is such that its end abuts against said stud when the bottom of said plug is approximately in contact with the end of said neck and that said internal thread can pass beyond said stud when the rotation of said plug is forced.

Avantageusement, ledit plot est un renflement vertical.Advantageously, said pad is a vertical bulge.

Selon un mode de réalisation préféré de l'invention, ledit plot prend appui sur une contre-bague située vers la base du col du flacon.According to a preferred embodiment of the invention, said stud bears on a counter-ring situated towards the base of the neck of the bottle.

La description qui va suivre et qui ne présente aucun caractère limitatif doit être lue en regard des figures annexées, parmi lesquelles:

  • La figure 1 représente en perspective, un flacon comportant un plot selon la présente invention.
  • La figure 2 est une vue en coupe de l'objet de la figure 1 selon la ligne II-II.
The description which follows and which is in no way limiting in nature must be read with reference to the appended figures, among which:
  • Figure 1 shows in perspective, a bottle comprising a pad according to the present invention.
  • Figure 2 is a sectional view of the object of Figure 1 along line II-II.

Ainsi qu'on peut le voir sur ces figures, un flacon désigné dans son ensemble par la référence 1, comportant le dispositif selon la présente invention, se compose d'un corps 2 et d'un col 3.As can be seen in these figures, a bottle designated as a whole by the reference 1, comprising the device according to the present invention, consists of a body 2 and a neck 3.

Ce col 3 est muni d'un filet 4 sur lequel sera vissé le bouchon (non représenté) du flacon 1. Ce filet 4 peut être continu on discontinu comme représenté sur la figure 1.This neck 3 is provided with a thread 4 on which the cap (not shown) of the bottle 1 will be screwed. This thread 4 can be continuous or discontinuous as shown in FIG. 1.

Vers sa base, ce col 3 comporte une contreba- gue 5, selon ce mode de réalisation, sur laquelle prend appui in plot 6. Ce dernier a la forme d'un renflement vertical.Towards its base, this neck 3 comprises a buttress 5, according to this embodiment, on which is supported in stud 6. The latter has the form of a vertical bulge.

Le plot 6 peut être également situé à l'extrémité basse du filet 4, ou à tout autre endroit du col 3 au-delà de cette extrémité.The stud 6 can also be located at the lower end of the net 4, or at any other location of the neck 3 beyond this end.

Quant au bouchon correspondant à ce flacon 1, il comporte un filet coopérant avec celui du col 3 et étant d'une longueur telle que son extrémité bute contre le plot 6 lorsque le fond du bouchon est au contact de l'extrémité 7 du col 3: l'herméticité est donc acquise. En exerçant sur le bouchon une force de rotation, le filet du bouchon passe au-dessus du plot 6; ce faisant, on obtient un blocage du bouchon sur le flacon et une bien moindre propension de ce bouchon à s'auto- dévisser.As for the stopper corresponding to this bottle 1, it comprises a thread cooperating with that of the neck 3 and being of a length such that its end abuts against the stud 6 when the bottom of the stopper is in contact with the end 7 of the neck 3 : the hermeticity is therefore acquired. By exerting a rotational force on the plug, the thread of the plug passes over the stud 6; in doing so, one obtains a blockage of the stopper on the bottle and a much lower propensity of this stopper to self-unscrew.

On notera tout particulièrement l'intérêt du dispositif selon la présente invention dans le domaine notamment de la parfumerie et de la pharmacie du fait que les flacons renferment des liquides volatils ou comprenant des principes actifs volatils.It will be noted in particular the advantage of the device according to the present invention in the field in particular of perfumery and of pharmacy because the bottles contain volatile liquids or comprising volatile active principles.

Il est bien évident que l'on no sortira pas du cadre de la présente invention en utilisant le présent dispositif pour fermer un pot ou un boîtier ou, de façon générale un récipient de toute forme.It is obvious that one will not depart from the scope of the present invention by using the present device to close a pot or a case or, in general, a container of any shape.
