Definitions

  • the invention relates to a childproof dropper / closure system according to the preamble of claim 1.
  • the purpose of the invention is to create a dropper / closure system with improved security of originality and improved security against unintentional opening by children, which is also simple in construction and method of manufacture.
  • the object of the invention is to provide a new, improved dropper / closure system of the type mentioned, which has a comparatively simple structure, can be produced inexpensively and thereby contains a child safety device, which opens the container thus sealed from accidental and dangerous opening Preserves children.
  • a plurality of locking fingers are provided on the outer circumferential wall of the container mouth, which have holding slots and which are spaced from one another such that they are arranged between them parallel to the longitudinal axis of the container mouth ,
  • Axial passage grooves form that are formed on the inner wall of the cap shell of the cup-shaped cap retaining cams, which engage in the locking position in the holding slots of the locking fingers provided on the container mouth and that the end of the suction cup pointing towards the container and encompassing the outer end of the pipette is integral with this Sauaer connected, a radially outward flange and an adjoining, axially oriented and with its free end portion pointing away from the container, in a relaxed state reaching approximately to the end face of the cap, in its outer End portion slightly radially inwardly bent ring spring element is formed, which is in the closed position such that the cap is held in its closed position on the container mouth, the retaining cam
  • the cap After use, the cap is put back on the container mouth and brought back into the childproof locking position by pressing and simultaneously rotating.
  • the dropper / closure system according to the invention consists of only a few parts and is correspondingly simple and inexpensive to manufacture.
  • the dropper / closure system according to the invention prevents containers from being opened accidentally and dangerously by children.
  • the cap is simply pressed axially downward against the spring pressure and then rotated.
  • the holding cams are pressed out of the holding slots and, due to the rotation, reach the passage grooves provided on the outer peripheral wall of the container mouth. These through grooves are formed by the adjacent locking fingers.
  • the holding cams can slide upwards in the axial direction when the cap is removed.
  • an embodiment of the child resistant dropper system of the present invention is numbered 10.
  • the container mouth 12 has a radially outward flange 14 which is below the Removal opening 16 is located.
  • the outer wall of the container mouth has a series of locking fingers 20 arranged on the circumference.
  • These locking fingers 20 extend around the circumference as shown and, in this example, are provided four times and are spatially separated from one another, thereby forming four uniformly shaped axial grooves 21 on the circumference, with which the locking cams of the cap during the fitting and removal of the cap, the interact below.
  • the locking fingers 20a have an axial foot 22a, which is arranged at an angle to a plane through the central axis AA of the container. These feet define an interface against which the cams of the cap interact during the fitting and removal process from the container, which is described in more detail below.
  • the locking fingers 20b have no axial feet, but can also be provided if necessary.
  • each locking finger has an upwardly inclined surface 24 that is adjacent the locking groove 26.
  • the bottom wall of the notch 26 is located a predetermined distance A and the bottom end 28 of the tapered surface 24 is a predetermined distance B from the axial end face of the container to serve a specific purpose, which is described in more detail below.
  • the cap has a generally cup-like shape and consists of a jacket 30 and an annular end face 32 formed thereon, which has a hole 34.
  • the cap has on its inside a series of inwardly directed and circumferentially spaced cams 36 adjacent to the lower edge of the shell. These cams interact with the locking fingers 20 of the container mouth to lock the closure on the container tamper-evident manner, as described in more detail below.
  • the suction element 40 of the dropper / closure system consists of a suction device 42, which is made of an elastically resilient material, such as. B. rubber or made of flexible plastic, and an extended drip tube or a pipette 44 made of rigid material with an annular disc 46 at the upper end, which snaps into an internal annular groove in the suction cup 42 to hold the pipette in the manner shown .
  • the suction cup has a radially outwardly directed enlarged flange 50 at its lower end, its predetermined diameter D, which is significantly larger than the diameter D1 of the opening 34 in the upper end of the cap, and a further relatively small, flexible flange 52, which is axial to the first Flange 50 is arranged.
  • the lower flange 50 has an upright ring 54 with a slightly inward, lip-shaped upper end 56 that extends from the outer peripheral edge and normally with the inner surface of the cap top in a manner as shown in FIG. 4, is in a positive interaction.
  • the base 58 of the lower flange 50 is arranged at a certain distance A1 (see FIG. 6) from the upper end of the locking cams 36.
  • the parts that make up the dropper / lock system are easy to assemble. So z. B. the pipette simply pressed into the suction element 42 until the washer 46 engages in the internal groove 48, which is arranged adjacent to the short upper flange 56. It should be noted that the hole in the suction cup is chamfered at the entrance to make it easier to assemble the pipe.
  • the suction / tube assembly is then inserted through the opening 34 in the upper part of the cap from the inside, the opening 34 of the cap having a diameter D1 which is slightly larger than the diameter D2 of the Suction cup 42 to enable the suction cup to be installed through the upper opening (see FIGS. 3 and 6).
  • the short flange 52 is flexible enough to slide through the opening 34 and, after being pulled through, abut against the upper annular end face with the ascending ring which is pressed against the inner surface of the annular upper part, and in the normal position of the parts against each other, as shown in Fig. 6.
  • the cap is simply placed on the container so that the cams 36 are engaged with the gaps between the locking fingers and pressed down against the wedge-shaped surfaces of the ascending ring .n.
  • the cap is then turned clockwise until the cams abut the inner edge of the axial foot of the locking fingers.
  • the cap is then released with the flange of the nipple pushing it upward so that the cams snap into the holding slot of the locking fingers in the closed position. In this position, the cams lock the cap against twisting in relation to the container and thus prevent all attempts to open the cap by simply turning, which is normal child behavior.
  • the cap If the cap is now to be opened, it is simply pressed axially downward against the wedge-shaped surfaces of the ring until the cams are free from the highest point of the receptacle. Then the cap is turned counterclockwise until the cams lie in the axial groove between the locking fingers. When the cap is released, it is pressed upwards by the spring action of the ring. In this position, the cams are located in the grooves 21 between the locking fingers, and therefore the cap can be removed from the mold with the drip device.
  • Fig. 7 shows a version of a suction element, as has already been described in the basic embodiments.
  • the lower flange 120 is designed such that from the end of the axial opening 122 of the suction cup the flange is designed in the form of a spring attached to the entire circumference with a spring lip 124, the spring lip 124 of which upper end 126 is directed inward to achieve the bias necessary to hold the cap with the dropper mount in the locked position.
