Definitions

  • This invention relates to a closure for a container, more particularly a closure comprising a closing cap which can be attached to the container by means of coupling means.
  • the invention can be applied on a variety of containers, however, in the first place it is intended to be applied with bottle-shaped plastic containers for liquid products, for example, containers for cosmetic products, detergents, foodstuff, drinks, toxic products, and so on.
  • the invention aims at providing a closure for a container whereby the closing cap can be kept in closed condition in an efficient manner, such that the contents of the container can not undesiredly come out of the container.
  • the invention relates to a closure for a container comprising a closing cap which can be attached on the actual container by means of coupling means, with as a characteristic that the coupling means at least consist of, on one hand, a first connection between the closing cap and the container, and, on the other hand, a second connection comprising a tubular part which, in coupled position, by means of respective couplings, cooperates with the closing cap as well as with the container.
  • the first connection consists of a rotatable coupling, more particularly a coupling which allows for that the closing cap can be attached to the container, removed therefrom, respectively, by means of a mutual rotation between this closing cap and the container.
  • this classical rotatable coupling use is made of a classical screw thread connection between the closing cap and, for example, the neck of the container.
  • Such rotatable coupling does not necessarily have to consist of classical screw thread and, for example, according to a variant also may consist of a bayonet locking, whereby a combined rotational and shifting movement is provided.
  • the tubular part preferably is provided over, on one hand, the closing cap and, on the other hand, a portion of the neck of the container and, in coupled condition, engages the closing cap as well as the exterior of the neck of the container.
  • the coupling between the tubular part and the closing cap consists of a screw thread coupling. The same is valid for the coupling between the tubular part and the container.
  • the coupling between the tubular part and the container shall consist of coupling parts engaging behind each other, or, alternatively, shall consist in the combination of a screw thread coupling and such coupling parts engaging behind each other.
  • the first connection and the second connection are such that the first connection cannot be undone as long as the second connection is not completely uncoupled.
  • the advantage is obtained that the closing cap can not be loosened in any respect, also, not loosened partially, as long as the second connection is not completely uncoupled, by which a coupling with a great safety is presented.
  • this is realized by making use of different screw thread for the first connection and the second connection, either screw thread directed in opposite sense, or screw thread with a different pitch.
  • the whole is provided with portions which allow for controlling whether the container already had been opened beforehand and/or with a child-proof system.
  • figure 1 represents the upper end of a bottle-shaped container which is provided with a closure according to the invention, whereby the left half is cut apart;
  • figure 2 represents the closure of figure 1 in dismantled condition;
  • figure 3 represents the closure of figure 1 in still another condition;
  • figures 4 to 6 represent three variants of the invention ;
  • figure 7 represents the embodiment of figure 6 in a previous position;
  • figures 8 to 11 represent another variant, whereby figures 8 and 11 represent two different positions and figures 9 and 10 represent the composing parts separately;
  • figures 12 and 13 represent two more variants;
  • figures 14 and 15 represent a further variant;
  • figures 16 and 17 represent two more particular forms of embodiment.
  • the invention relates to a closure for a container 1 which is provided with a closing cap 2.
  • This closing cap 2 by means of coupling means 3, can be provided on the container 1 , in the represented example on the neck 4 of this container 1, respectively, whereby these coupling means 3 according to the invention provide for a particular kind of connection which effects an additional locking for the closing cap 2.
  • the coupling means 3 at least consist of, on one hand, a first connection 5 between the closing cap 2 and the container 1 and, on the other hand, a second connection 6 which comprises a tubular part 7 which, in coupled condi- tion, by means of respective couplings 8-9, cooperates with the closing cap 2 as well as with the container 1.
  • the first connection 5 consists of a rotatable coupling and, in the represented example of figures 1 to 3 , is formed at the inward-directed side 10 of the closing cap 2 and the outward-directed side 11 of a part, more particularly the aforementioned neck 4 , of the container 1.
  • a classical screw thread coupling formed by internal screw thread 12 and external screw thread 13.
  • the coupling 8 between the tubular part 7 and the closing cap 2 is situated between the inward-directed side 14 of the tubular part 7 and an outward-directed side 15 of the closing cap 2.
  • This coupling 8 furthermore also consists of a screw thread coupling, formed by, respectively, internal screw thread 16 at the side 14 and external screw thread 17 at the side 15.
  • the coupling 9 between the tubular part 7 and the neck 4 also consists of a screw thread coupling, formed by internal screw thread 18 at the interior side of the tubular part 7 and external screw thread 19 on the neck 4.
  • the two couplings 8 and 9 of the tubular part 7 are situated on substantially coaxial mantle surfaces, which, in the embodiment of figures 1 to 3 , is obtained in that the closing cap 2 is provided on a narrowed extremity 20.
  • the whole unit is made in such a manner that the tubular part 7 can be provided over the upper extremity 21 of the closing cap 2 on the container 1, more particularly over the closing cap 2 and the neck 4.
  • the second connection 6 comprises one or more, in this case, two, zones 22-23 which are free of coupling means, in such a manner that in the loosened condition of the tubular part 7, this latter drops freely downward, at least over a well-defined distance, as can be seen in figure 3.
  • the represented connections 5 and 6 are of such a kind that the first connection 5 can not be undone as long as the second connection 6 is not completely uncoupled, which in this case is obtained in that for the first connection 5 and the second connection 6, use is made of different screw threads, 12-13 on one hand and 16-17-18-19 on the other hand, with which it is intended that the screw threads at the first connection 5 either are directed in opposite sense in respect to those of the second connection 6, or are made with a different pitch, as a result of which, as will be explained in the following, a simultaneous screwing of the closing cap 2 and the tubular part 7 is excluded.
  • Figure 1 shows the closed and blocked condition, whereby all screw threads are engaged.
  • the tubular part 7 hereby prevents a turning of the closing cap 2.
  • the simultaneous unscrewing of the tubular part 7 and the closing cap 2 are excluded as a result of the use of screw threads which differ in respect to each other and preferably are directed opposite in respect to each other. This latter becomes clear from the figures, whereby the screw threads 12-13 are made as right-handed screw thread, whereas the screw threads 16-17-18-19 are made as left-handed screw thread.
  • the closing cap 2 By rotating the tubular part 7 downward, as represented in figure 3, until at least the coupling 8 is undone, the closing cap 2 subsequently can be unscrewed in a classical manner. After it is closed again, the tubular part 7 can be drawn upward again and be screwed tight again in order to obtain the locked condition of figure 1 again.
  • the closing cap 2 comprises a stop 24 for the upper extremity 25 of the tubular part 7.
  • This stop 24 consists of a collar provided at the closing cap 2 which has the same or almost the same diameter as the exterior diameter of the tubular part 7.
  • a hygienically closing whole is obtained whereby, at the upper side, no dirt or such can penetrate between the closing cap 2 and the tubular part 7.
  • the fact that the tubular part 7 can not be unscrewed from the container 1 when the closing cap 2 is screwed tight, can be considered an additional safety.
  • tubular part 7 has to be provided over the neck 4 before the closing cap 2 is screwed on the neck 4.
  • the coupling 9 between the tubular part 7 and the container 1 consists of coupling parts engaging behind each other which are made as a barb structure 26 , such that the tubular part 7 can easily be shifted over the container 1, more particularly the neck 4, until a locking at the barb structure 26 is created.
  • the barb structure 26 consists of a collar 27 at the neck 4 and an inward-directed collar 28 at the tubular part 7, whereby on one of these collars, in this case the collar 27, an inclination 29 is provided which allows for that the tubular part can be pushed downward with the collar 28 over the collar 27, but can not be drawn back over the collar 28 with the normal manual force.
  • tubular part 7 shall be able to make a connection with the closing cap 2 and with the neck 4 of the container 1 at the same time, this tubular part 7 has to be longer than the closing cap 2 (without the stop portion), when one wants to displace the tubular part 7 up to against the uppermost stop in order to make the second connection. Also, it must be possible to screw the tubular part 7 downward over a sufficient length along the neck 4 of the container 1 in order to undo the connection with the closing cap 2.
  • the coupling 9 consists in the combination of a screw thread coupling as well as the aforementioned barb structure 26.
  • Figures 6 and 7 also represent an example of an embodi- ment comprising a portion 30 which allows to control whether the container 1 has already been opened beforehand.
  • the portion 30 consists of a part which can be broken off and which is fixed at the tubular part 7 and which breaks off as soon as the container 1 is opened for the first time.
  • This portion 30 which can be broken off consists in a part provided at the upper side of the tubular part 7 which extends over the upper side of the closing cap 2 and is connected to the tubular part 7 by means of a narrowed portion 31.
  • FIG. 8 to 11 another form of embodiment is represented whereby the coupling means 3 are provided with a child-proof system consisting in that the second connection 6 makes use of a rotatable and shifting coupling, whereby shifting exclusively is possible in one or more well-defined positions.
  • the aforementioned screw threads 16-17-18-19 are made in an interrupted manner, such that zones 32 free of screw thread are obtained which allow for that in the positions, whereby the thus remaining screw thread segments are displaced in respect to each other, a shifting V is possible.
  • the screw thread 17, however, preferably has a continuous portion at the top.
  • a protrusion 33 provided on the neck 4 which forms a stop for the tubular part 7 when this latter is rotated downward and thereby comes into contact with a stop surface 34.
  • a groove 35 is provided in the tubular part 7, which groove allows for that this part 7 can be completely shifted downward when the protrusion 33 is located precisely in front of the groove 35.
  • Figure 12 represents a variant whereby the coupling 8 is situated between the tubular part 7 and the closing cap 2 , at the outward-directed side of the tubular part 7 and an inward-directed side of a wall part 36 pertaining to the closing cap 2.
  • Figure 13 finally represents an embodiment whereby not only the same is valid as described heretofore in respect to figure 12, but at the same time the screw thread coupling between the closing cap 2 and the container 1 is situated at the interior side of the neck 4.
  • tubular part does not have to extend continuously around the circumference and, for example, may show recesses and openings.
  • the zone 37 is made such that the part 7 during uncoupling, starting with the condition of figure 14, successively has to be unscrewed with the screw thread portions 16A-16B from the screw thread portions 17A-17B, subsequently, as represented in figure 15, has to be displaced against the force of a spring 38, as the screw thread portion 16A has to be engaged with screw thread portion 17B, and finally, with the screw thread portion 16A, can be screwed completely over the screw thread portion 17B, after which the closing cap 2 can be unscrewed.
  • a displacement against the force of the spring has to be performed, a child-proof system is created.
  • the tubular part 7 can consist of two concentric sleeves, whereby the entire tubular part can only be rotated by means of an axial pressure, followed by a rotation of the exterior sleeve.
