Definitions

  • the invention relates to a closure cap made of plastic, in particular for glass containers, with gripper segments connected to a jacket part spanning the container opening via material weak points and pivotable into a vertical position with mutually complementary profiling in the closed position on the mutually facing side surfaces.
  • a crown closure in which segments starting from a base via an annular groove are connected to one another in the closed state of the crown cap by means of tongues and grooves in the side surfaces thereof.
  • This closure is opened either with the aid of a crown closure opener via a predetermined breaking point provided on the edge of the closure part or via a tear-off tab and a tear-off ring integrated in the closure.
  • the segments are pressed against the bottle neck from a position inclined at approximately 30 °.
  • the demolding closure caps produced in this way at an angle of 30 ° require considerable effort in their manufacture due to the undercuts and grooves in the segments.
  • a closure cap made of plastic, in particular for injection and infusion bottles, is described in DE-U 88 05 665.
  • this cap In the starting position, this cap has horizontal, curved, rectangular gripper segments.
  • a homogeneous design of the gripper closing part is not possible since the side surfaces of the gripper segments do not overlap, but only abut each other. If crushing of material in the area of the connection point to the jacket part is to be avoided, a certain distance between the segments is necessary.
  • the segments pivoted against the bottle neck can therefore not be locked by mutual welding, but must be done by means of a separate securing element (securing ring).
  • a non-positive connection is made here just as little as with the solution according to the Swiss patent specification.
  • the invention has for its object a closure cap made of plastic, in particular for glass containers, with gripper segments connected to a jacket part via material weak points and pivotable into a vertical position with one another in the closed position on the mutually facing side surfaces to create additional profiling, which, starting from a rationally manufactured closure cap with horizontal gripper segments in the starting position, enables its intimate connection to form a closed outer surface in the vertical closed position.
  • the side surfaces of the gripper segments are chamfered in a closure cap of the type shown and thereby overlap each other in the closed position, while the material weak point between the jacket part and the gripper segment to the respective edge region of the gripper segment is either closed by a material accumulation or is kept clear by a notch.
  • the gripper segments are welded to one another in the closed position in the region of their overlapping side surfaces and mutually complementary profiles.
  • the gripper segments have inwardly directed gripping edges which grip under the bottle neck and form a captive locking part in the closed position, wherein the profiling of the gripper segments can consist of mutually complementary, form-fitting interlocking hooks and receptacles. It is expedient if the gripper segments are horizontally formed on the casing part in the starting position. It is particularly advantageous to provide the material weak point between the jacket part and the gripper segments on the outer and inner circumference with a molded bevel. With a special one According to an embodiment of the invention, the gripper segments are rectangular in plan view and arc-shaped in cross-section, a tab being formed on the gripper segments.
  • a cover part which exposes a seal or an opening is provided in the jacket part and has an annular, outwardly projecting clamping lip on the inside, which is provided on its circumference with curved, outwardly projecting bulges which run out to the beginning of the inside part of the cover.
  • a ring can be formed on the outside of the cover part, which is cylindrical on the inner circumference and runs out in an arcuate and / or chamfer shape on the outer circumference inwards to the cylindrical inner circumference.
  • the closure cap made of plastic has on its shell part 2 (FIGS. 1-5) surrounding a bottle neck 3 (FIG. 4) a closing part 9 (FIGS. 4 and 5) which engages under an undercut edge 4 (FIG. 4) of the bottle neck 3 and has an expandable cover part 6 (FIGS. 4 and 5) which exposes a seal 5 (FIG. 4).
  • the closing part 9 (FIGS. 4 and 5) is formed by so many grippers 8 and gripping edges 8b arranged in the jacket part 2 (FIGS. 1-5) that the gripping edges hooking behind the bottle neck edge 4 (FIG. 4) in the closed position and grippers are connected in terms of area and joints (Fig. 5).
  • the grippers 8 and gripping edges 8b are integrally connected to the jacket 2 via molded-on material weak points 7 (FIGS. 1-5) in such a way that when closed from the horizontal to the vertical position, a closed material weak point, especially at points 7b (Fig. 1 and 3) is guaranteed without crushing the material. Likewise, notching at points 7a (FIG. 2) can avoid crushing of material.
  • the formed in this material weak points 7 against the bottle neck 3 (Fig. 4) pivotable gripper 8 are designed so that when the closing process is finished, they are surface-tight and joint-tight to form a non-positive and form-fitting surface that is closed around the bottle neck 3 (Fig. 4) 9 (Fig. 5) are connected.
  • the grippers can be designed in various geometric shapes.
  • the cover part 6 (FIGS. 4 and 5) is equipped with a handle part 10 for pulling the cover part out of the closure cap.
  • the grip part is cylindrical on the inner circumference 11 (FIG. 4) and runs in the outer circumference 11a in the form of an arc and bevel or in a combination thereof inwards to the inner circumference.
  • the lid part 6 is formed on the closure cap 1 so that it has a thin-walled clamping lip 14 (FIG. 4) in the inner lid part 15 (FIG. 4) which is formed at the bottom or to the side and is formed in various geometrical shapes and which becomes apparent during the closing process Bends the bottle neck down or up on the bottle neck and thus fits tightly against the bottom of the cap or inside the bottle.
  • FIG. 1 and 2 show the initial shape of the closure cap, in which the curved grippers 8 lie in a horizontal plane and protrude outwards from the casing part 2.
  • the necessary notches can be seen at points 7a (FIG. 2) or the material accumulations at points 7b (FIGS. 1 and 3), so that there is no crushing of the material during the closing process.
  • the closure cap is placed on it and then the grippers 8 are pressed downward against the bottle neck 3 via their corresponding preformed material weak points 7 (FIG. 4). This preforming is necessary so that there is no white break when swiveling from the horizontal to the vertical position. Likewise, in the closed position there is a closed and joint-tight surface 9 surrounding the bottle neck (FIG. 5).
  • the grippers 8 can be designed in such a way that there are grippers 8 lying next to one another with mutual locking hooks 12 and locking receptacles 13 (FIGS. 3 and 5) in various geometric shapes and their combination with the mutual overlapping of the tabs in order to create a neck 3 to form peripheral surface 9 (FIGS. 4 and 5).
