Definitions

  • the present invention relates to a container comprising a container neck with an external thread, and a closure with an internal thread adapted to engage the external thread of the container neck to bring the container from an open condition to a closed condition and vice versa, in which said external thread extends along at least a part of the periphery of the container neck, in which the closure comprises a closure skirt and a securing member which at a first section is hingedly connected with the closure, and which has a second section opposite relative to said first section, and in which a catch embodied in the safety element in the closed position of the container is adapted to be brought into engagement with a recess in the container neck in order to thus obtain a secured condition, in which turning of the closure relative to the neck of the container is prevented, and in which the securing member is received in and kept in the closure, the closure comprising means for engaging corresponding means in the second section of the securing member.
  • So-called child-proof containers for preventing children from getting access to the contents of the container are known in many different embodiments.
  • the principle of the child-proofing resides in that opening of the container demands a combination of operations which are beyond the motoric capability and strength of the child, like for instance simultaneous or subsequent pressing and turning, squeezing and turning, etc., but which without any greater difficulty may be done by grown-ups.
  • a container of the type mentioned by way of introduction is known from DK patent no. 159,542.
  • the securing member for this container is only kept in the closure by the friction between the engagement means on the closure and the securing member, respectively. It may be helpful or obvious for the child to try to lift the securing member, following which the closure may simply be screwed off.
  • Child-proof closures which are locked in the closed condition of the container, are among others known from US-A- ,838,441 and US-A-4,790, 42 which disclose a securing principle comprising deformation ot the closure for release of locking means, following which the closure may be lifted and pressed up to an open condition. As it i ⁇ thus only the closure which is lifted to give access to the content, the container may be inadvertently opened, as deformation and lifting may take place in one and the same condition.
  • Thi ⁇ has the effect that it becomes necessary to put great demands on the rigidity of the closure, so that children cannot open it on account of having too little strength, which on the other hand means that persons with reduced movability and strength of the fingers, like for instance rheumatic sufferers, cannot easily open the container.
  • the last-named fact induces people to refrain from activating such a precautionary measure.
  • a container which is characterized in that the closure further comprises an external closure portion with a closure skirt and a top section for receiving the securing member in the secured condition of the con ⁇ tainer, that the engagement means of the closure are designed as a protrusion extending from the closure skirt of the external closure portion for locking engagement with a protrusion extending downwards from the securing member near or close to the free end of it ⁇ second section, and that the locking engagement between the protrusions can only be released by defor ⁇ mation of the external closure portion in predetermined deformation zones in the secured condition of the container in order to thus release the securing member from its ⁇ ecured condition for the attainment of the closed condition of the container.
  • the inner closure portion may be made with arbitrary rigidity and thickness to meet the strict requirements in respect of among others imperviousness which are made within the field of use of the container, whereas the external closure portion may be made with relative ⁇ ly less rigidity in order to increase deformability and thus user comfort.
  • FIG. 1 shows a segmental perspective view of a container in a first embodiment of the invention in closed condition

  • the container 1 has a body portion 2, which at the top is finished by a container neck 3, and a closure, gen ⁇ erally designated 4.
  • the container neck 3 has in the embodiment ⁇ hown an external thread 5 with a flap 3a fixedly connected with the container neck, but the thread may also be made on a separate thread piece for connection with the container neck or on the very container neck.
  • the closure 4 has an internal closure portion comprising a closure skirt 6, in which an internal thread 7 is provided for engagement with the external thread 5, and a top section 8 closing the neck of the container 3 when the closure 4 is screwed on.
  • the top section 8 is in view of an improved detainment in and sealing of the container neck provided with an addi- tional skirt 6b positioned radially within the skirt 6, ⁇ aid additional skirt protruding in the closed condi ⁇ tion of the container downwards into the container neck.

  • the closure 4 is deformed by pressing with the thumb and forefinger of one hand in the areas marked by arrows A, whereby the areas marked B move outward ⁇ until the po ⁇ ition ⁇ hown by intermittent line ⁇ in Fig. 4 ha ⁇ been reached.
  • the securing member 11 i ⁇ lifted and swung to the position shown in Fig ⁇ 1 and 5.
  • the container is now in its closed condition and is opened by screwing off the closure 4 from the neck of the container.
  • the securing member 11 may at the screwing off be u ⁇ ed a ⁇ a lever, which i ⁇ an advantage when a per ⁇ on suffers from reduced mobility and strength of the hands, as by opening he may for instance grasp the container body with both hands and place the securing member in abutment with the edge of a table or the like and subsequently unscrew the closure by turning the con ⁇ tainer body itself. Closing and securing of the con ⁇ tainer takes place in reverse order.
  • a container 31 is shown in its closed, but not ⁇ ecured condition, i.e. in which the closure 34 has been ⁇ crewed onto a body part 32.
  • the container ends as before with a container neck 33 with a flap 33a, in which the external thread 35 has been provided.
  • the closure 34 comprises an internal closure portion with a closure skirt 36 with an internal thread 37 and an additional skirt 36b extending downwards into the neck of the container, and a top section 38. Radially outside the internal clo ⁇ ure portion an external closure portion with a closure skirt 39 and a top section 40 is provided.
  • the ⁇ ecuring member 41 is like in the embodiment described above designed a ⁇ a rod-shaped part and is in a first section 41a at its one end 42 hingedly connected with the closure 34.

Abstract

L'invention concerne un récipient ayant un col (3, 33) à filet extérieur (5, 35), et un dispositif de fermeture (4, 34) à filet intérieur (7, 37) conçu pour s'adapter au filet extérieur du col. Le récipient peut passer de l'état ouvert à l'état fermé, et vice-versa, par l'intermédiaire d'une pièce de sécurité (11, 41) qui, dans une première section (11a, 41a) est articulée avec le dispositif de fermeture et qui, dans une seconde section (11b, 41b) opposée à la première section, est libérée par déformation de la partie extérieure du dispositif de fermeture, selon des zones de déformation prédéterminées lorsque le récipient est à l'état protégé aux fins de sécurité, ce qui a pour effet de libérer la pièce de sécurité de sa position sécurité et, partant, de passer à l'état fermé simple permettant le dévissage du dispositif de fermeture et son retrait du récipient.
