Definitions

  • the present invention relates to a childproof screw closure which is resistant to overturning (known from US Pat. No. 4,436,211).
  • Such childproof screw caps are used for storage containers with household chemicals or the like, in particular for bottles containing cleaning liquids.
  • the closure is also for other containers, such as. B. suitable containing medicinal products.
  • Closures for detergent bottles are known in which the opening is carried out by pressing opposing screw cap parts together and simultaneously rotating them counterclockwise.
  • the childproof lock consists in corresponding stops of the screw cap which have radially spreading catches on the bottle, the stops being behind them in the closed state.
  • the screw cap is formed in two parts, the periphery represents the actual (carrying the stops) elastically deformable by hand force, inside a threaded part is arranged concentrically.
  • the present invention has therefore set itself the task of creating a screw closure of the type described above, which can be manufactured in an injection molding process while increasing the functional reliability.
  • the separate internal threaded part is understood to mean a preferably cylindrical part with an internal thread.
  • the outer cap shell is formed on the head side in such a way that it can be pressed together by hand to release the stops located behind the catches.
  • the design as a two-start thread each with a wrap angle of s180 °, creates two half-threads on the spout, the upper lower edge of the half-thread running out over the upper edge of the respective lower half-thread.
  • Such a thread can be produced without an undercut, but is limited to a relatively shallow pitch and is therefore not secure against overturning.
  • the over-tightening device is therefore separated from the screwing function and is designed as a pair of abutting edges and thresholds.
  • the thread starts and their pitches are designed so that the abutting edges hit the sleepers when the closure is fully screwed in, with the cap also normally resting on the vessel envelope.
  • a thread depth of approx. 0.5 mm has proven itself for the thread, as this simultaneously combines sufficient stability and function with the required demoldability.
  • polypropylene has proven itself well because of its material properties.
  • the closures according to the invention produced therefrom engage precisely, snap in childproof even after frequent use, and the spring constant and thus the manual force required for opening remain constant. A wear and tear, particularly abrasion on the material edges, which could impair the functional safety could not be observed.
  • the thread on the spout is advantageously located on a ring arranged on the spout.
  • the thread area can be enlarged, on the other hand, this ring can also serve as a stop for a deferred and z. B. secured by a bouncing spray nozzle or the like.
  • a thickness of approx. 2 mm has proven itself as the shape geometry for sleepers and notches and a width of at least approx. 1 mm for the sleepers, whereby the dimensions can be easily adapted to the respective material conditions.
  • a smaller design can also lead to malfunctions in functional safety when using the relatively hard and resistant polypropylene.
  • the closure is made of the same material with the upper part of the vessel, the upper part of the vessel being produced by injection molding with its lower part, for. B. is connected by bouncing and welding or gluing.
  • FIG. 1 shows the pouring spout 1 to be closed, which is arranged on a storage bottle 13.
  • This pouring spout carries a ring 11, in which two half gears of an external thread 2 are formed, which do not overlap or only overlap to an insignificant extent, ie. that is, the upper edge 14 of the thread half-way shown on the right begins below the lower edge 15 of the thread half-way shown on the left.
  • the catches 3 and the sleepers 4 are also shown on the plate 16 of the storage bottle 13, which carries the spout 1, the rear sides of the sleepers in the present case running out into the rear sides of the catches 3.
  • a bouncing ring 12 is arranged above the ring 11 carrying the two-start thread 2.
  • a spray nozzle can be pushed over this and secured in the nozzle by means of the bouncing ring 12 and a corresponding counterpart, whereby it is prevented from slipping downwards by the ring 11.
  • Fig. 2 shows the previously described upper part of a storage bottle in a perspective top view.
  • the pourer 1 there are the openings 17 through which the liquid content is dispensed from the bottle.
  • the sleepers 4 are connected opposite, which run into the notches 3.
  • the expansion wedges 19 (FIGS. 3, 4) are pressed to move them over the obstacle of the catches 18 and on their back flanks into which Close expanding wedges to prevent children from opening them.
  • Fig. 3 shows the screw cap 5 for the storage bottle. This consists of the outer casing 20, the actual cap and the separate internal threaded piece 7 connected to the casing 20 on the head side. In the background of the casing 20 an expanding wedge 19 can be seen.
  • the sleeve 20 and the internal threaded piece are connected to one another in such a way that the sleeve 20 springs sufficiently for closing and opening.
  • the screw cap has ribs 21, offset by an angle of 90 ° to the expansion wedges 19, recesses 22 on the outside of the casing 22, which prevent opening at the wrong angle.
  • the corresponding 2-thread internal thread 6 is arranged on the lower part of the internal thread piece 7.
  • the internally threaded piece has opposite wedge-shaped incisions 8 which form the abutting edges 9 which abut the sleepers 4 in the screwed-on state and prevent over-tightening.
  • the angle between the securing rear edges of the expanding wedges 19 and the abutting edges 9 corresponds to the projected width of the sleepers 4.
  • Fig. 2 shows the cap in plan view from below.
  • the expansion wedges 19 are located on the casing 20, the spacing of which can be increased perpendicularly to the casing by the application of force.
  • the internal threaded piece 7 runs out against the abutting edges 9, which are reinforced here by small plates 10.
  • the ribs 21 are located in the upper part of the closure cap and on the inner surface of the internal threaded piece 7.
