Definitions

  • This invention relates to safety closures for containers which can be readily applied and removed by one having knowledge of their operation, and which are relatively safe in the hands of children because they are usually unable to manipulate the closures in the required manner to remove them from the containers.
  • the closure described herein comprises inner and outer caps with tee,th formed on the skirts of the caps for turning and applying the inner cap on the container when torque is applied to the outer cap in the application direction.
  • t-he outer cap is turned in the removal direction, however, the theeth on the respective caps are not engaged so that the inner cap will not be turned.
  • it is necessary to exert sufficient downward force on the closure so that horizontally and radially extending teeth on the outer cap are brought into engagement with cooperating teeth on the inner cap and, when a torque is simultaneously applied in the removal direction, the inner cap will than be turned for removal from the container.
  • Closures of these kind should be as fool proof as possible and not open when children rotate the outer cap relative to the inner cap without the accompanying simultaneous downward thrust to engage the teeth on the ends of the inner and outer caps
  • Fig. 1 is an enlarged, perspective view of a safety closure embodying tne novel features of the present invention
  • Fig. 2 is a bottom view of the outer cap with portions cut away and with the inner cap removed;
  • Fig. 3 is a cross-sectional view taken generally along the line 3-3 of Fig. 1; the left part showing the safety closure in its normal position while no removal force or torque is applied, the right part showing the safety closure while exerting a downward pressure upon the outer cap in the direction of the arrow;
  • Fig. 4 shows another embodiment of the invention in a cross-sectional view similar to Fig. 3.
  • the inner cap and the outer cap are modified;
  • Fig. 5 shows still another embodiment of the safety closure of the present invention, also in a cross-sectional view similar to Fig. 4;
  • Fig. 6 and Fig. 7 show partially a bottom view and a top view of the outer cap shown in Fig. 4 in its assemhled position (s). (The scale of the various embodiments shown. may differ for purposes of clarification only)
  • a safety closure 1 eabodying the present invention comprising an outer cap, indicated generally at 2, overlying an inner cap, indicated generally at 3, with the inner and outer caps being concentrically aligned.
  • a generally cylindrical skirt 4 of the inner cap 3 is formed with a container fastening means such as a spiral screw thread 5.
  • one or more ratchet teeth, indicated generally at 6, on the skirt portion 4 of the inner cap 3 project radially and generally coaxially outwardly for engagement with one or more ratchet teeth, indicated generally at 7, on the inner side of a depending generally cylindrically shaped skirt position 8 of the outer cap 2.
  • the cooperating teeth 6 and 7 are shown in a vertical position. However they may instead also be placed in a generally sloping position under say 45 °.
  • the upper portion of the inner cap 3 is further shaped in such a manner that an upper container rim is received in the circumferential space 9 created by the skirt portion 4 being turned back in itself at 10.
  • the central upper portion 11 of the inner cap 3 is of cylindrical shape and its flat top surface 12 lies nearly in the same plane as the concentrically arranged top surface portion 13 of the outer cap 2.
  • the annular connecting por tion 14 of the inner cap 3 betweenits/skirt portion at 10 and its cylindrical top surface 12 will perfectly house and thereby seal any irregularity processed on the container neck portion to be located in the space 9, thereby avoiding any possible leakage of liquid from the container.
  • the lower depending skirt portion on the outer cap 2 is provided with a cut b ack cylindrical portion 15 which narrows to the bottom part into a thicker annular retaining portion 16.
  • the inner cap 3 is further provided at its lower part with an annular protruding rim 17 which, in the assembled position of both caps 2 and 3 of the safety closure 1, is retained within annular portion 16 thereby enabling the coaxial movement of the depending skirt portion 15 with respect to the inner cap 3.
  • the outer cap 2 continues from its horizontal flat top surface 13, which surrounds the top surface of the inner cap 3 concentrically, into one or more, but preferably six depending diverging flexible segments 18 or resilient lips 18, the bottom ends of which normally rest upon the horizontal annulus 19 of the inner cap 3 as shown in Fig. 3. The function of these segments 18 will easily be understood.
  • the safety closure may than be opened only after e.g. tearing off the covered part of its central portion whereafter the desired safety function can be performed.
  • FIG. 4 at left and at right respectively the unoperational and the operational position of another safety closure is demonstrated in a cross- sectional view.
  • the outer cap 102 houses the inner cap 103 which skirt por tion 104 is provided with an internal threaded portion 105.
  • the upper skirt portion 104 tapers and is externally provided with radially extending teeth segments 106 and other teeth 107 are formed on the inner wall portion 108 of the outer cap 102.
  • the usual container rim of the opening portion of the container (not shown) is located in the space 109 after the closure 101 is screwed upon the container, the wall portion 110 converging into an annular connecting portion 114 forming the bottom part of the cylindrical central portion 111 on the inner cap 103 which ends in the upper wall portion 112.
  • the outer cap 102 is integrally formed with a number of six separately disposed depending resilient lips 118 which are integrally formed with its surface portion 113. Contrary to the resilient lips in the embodiment of the safety closure as shown in Fig. 3, now the lips 118 have a substantial length and/areof/asuchmaterial strength tending to resist with their lowermost ends inwardly directed radial forces. Exerting a downwardly directed pressure, shown by an arrow , upon the outer cap 102, the lowermost ends of the lips 118are forced along the annular surface of the converging portion 110 downward and against the cylindrical wall portion 111, thereby causing engagement of the teeth 107 and the teeth 106.
  • the wall portions of the inner cap 103 which are located at the inside of the container opening are conically shaped in -such a way as to guide and seal off the opening of the container perfectly, even if irregularities would appear as a result from the production method used.
  • the cap 102 is centrally guided by the cylindrical wall portion 111.
  • Fig 5 discloses a similar safety closure as just described, however with few differences.
  • the mouth of the container is somewhat wider and the central cylindrical wall portion 211 is integrally connected to a conical lower wall portion before it continuous into the connecting annular portion 214.
  • a conical ring portion 222 is integrally formed with the outer cap 202 to ensure the correct position of the uppermost central portion 212 of the inner cap 203 with respect to the outer cap 202.
  • the cooperating teeth 206 and 207 respectively, the retaining ring portion 216 and the protruding rim portion 217 are accordingly shown.
  • Figs. 6 and 7 the position of some parts with respect to the outer cap 102 of Fig. 4 are additionally shown in sofar as the cross-sectional view does not always sufficiently disclose their location.
  • the safety closure according to the present invention is preferably molded from relatively hard non-yielding plastic materials, such as polypropylene, polyethylene or the like, depending on the various requirements relating to the container, the liquid and the duration of expected container use and the desired opening and closing forces to be applied by the average user of a container for household purposes.

Abstract

Une fermeture de securite pour conteneurs consiste en une combinaison assemblee d'un couvercle interieur (103) loge et entoure par un couvercle exterieur (102). Le couvercle interieur (103) est pourvu le long de sa surface circonferentielle ou de sa portion de jupe (104) d'une serie de premieres dents (106), la portion de jupe interieure du couvercle exterieur (102) est pourvue d'une serie de secondes dents (107) qui peuvent etre amenees en engagement avec les premieres dents (106) par un mouvement coaxial relatif des couvercles interieur et exterieur. La fermeture de securite peut etre devissee du conteneur ou vissee sur l'embouchure du conteneur respectivement seulement en exercant sur le couvercle exterieur (102) une pression vers le bas provoquant l'interengagement des dents (106 et 107), apres quoi l'on peut faire tourner le couvercle interieur (103). Des elements ressorts ou levres (118) dependant de la portion de paroi superieure (113) du couvercle exterieur (102) opposent une resistance elastique a la pression vers le bas exercee sur le couvercle exterieur, lesquelles levres (118) se plient contre une portion de paroi (110) du couvercle interieur (103) qui est situee a l'interieur de l'embouchure du conteneur et qui converge de maniere annulaire. Le couvercle interieur (103) est pourvu d'une portion cylindrique centrale (111) s'elevant depuis l'anneau (114), les levres (118) pouvant etre actionnees dans l'espace compris entre la portion cylindrique (111) et la portion d'embouchure interieure du couvercle interieur. La surface superieure centrale (112) du couvercle interieur (103) est reliee de maniere rigide et solidaire a la portion restante du couvercle interieur (110) de maniere a resister aux charges de poids placees sur la fermeture de securite meme si la surface du couvercle exterieur (113), entourant la portion centrale (112), peut etre legerement enfoncee par celles-ci. La surface de la portion cylindrique centrale (111) possede la forme d'un guide central pour la bordure du couvercle exterieur
