Definitions

  • Screw cap for wide-neck containers which is provided with a tamper-evident device.
  • the invention relates to a screw closure according to the preamble of claim 1.
  • Screw closures with originality safeguards are known, the purpose of the originality safeguard being to be able to determine the first opening of the closure or removal of the cover by an optical check.
  • a securing ring is used for such an originality assurance, which is connected to the cover via webs and tears when the cover is unscrewed or separates from the cover, so that any manipulation of the cover is readily recognizable from the outside.
  • the object of the invention is to provide an easy to manufacture and functionally reliable screw cap for wide-neck containers, which is provided with a tamper-evident device.
  • the invention is characterized in that locking lips are arranged, in particular formed, on the safety ring which, in the closed position of the cover, engage behind a closure part formed on the container neck or a corresponding projection of the container neck and brace it when opened, so that when screwing on of the cover the locking ring is destroyed and thus the tamper-evident is ensured.
  • There is also an overrun cam or several Running cams are arranged in such a way that when the cams overflow through the latching lip (s) or the locking ring when the screw closure is opened, the locking ring expands, causing a break due to weak or predetermined breaking points formed on the locking ring of the circlip occurs.
  • the arrangement of the overrun cams depends on the design of the cover and / or the neck of the container, but the arrangement and design must be such that either the locking lip or a section of the safety ring is in the opening phase of the cover or screw cap runs over the overrun cam and thus there is a widening of the locking ring which, due to the tensioning over the tongue on the container neck, cannot move upward, so that the locking ring breaks and this can then be removed from the container without residue .
  • the latching lips expediently protrude inwards with respect to the securing ring, preferably at an acute angle to the vertical, obliquely inwards and upwards.
  • a total of four tongues are arranged on a securing ring, with a uniform spacing from one another at an angle of 90 ° to one another.
  • the weak points of the securing ring are expediently formed by grooves or notches, in particular V-shaped grooves, which are worked into the securing ring from the outer surface.
  • V-shaped grooves or notches film-like or web-like remains remain at several points over the circumference of the locking ring Areas that break when the retaining ring is appropriately processed.
  • the locking ring can then be removed from the bottle without further notice, the omission of the locking ring compared to an originally closed container being optically conspicuous.
  • a primary seal can be omitted, but a secondary seal is expediently implemented, either by a sealing ring arranged on the cover base or a sealing washer, by a compound layer applied to the cover base or by integrally formed sealing lips on the cover base .
  • a gas-resistant barrier layer can be applied to the outside of the cover base by the so-called in-mold process.
  • an expediently multilayer aluminum foil is introduced into the mold for the production of the lid and then the plastic material is injected, so that there is an intensive connection of the aluminum foil as a barrier to the lid. It is also possible to produce the cover with the seal by spraying two materials, so that there is a quasi one-piece cover with seal.

  • FIG. 14 shows a view of the closure according to the FIGS. guren 9 to 13 as well
  • FIGS. 1 to 8 a screw closure with a lid 1 and a locking ring 2 is provided for a wide-necked container, the lid and the locking ring essentially having a square plan with sides bent outwards, as best seen in FIG View in Figure 1 results.
  • the cover 1 consists of a cover base 3 and a wall 4, wherein in the embodiment according to FIG. 2 a sealing ring 6 is accommodated in the cover base 3 between ribs 5 projecting downwards, which can be designed, for example, as a compound.
  • the locking ring 2 serves as originality assurance, ie for visual control as to whether the cover has already been opened.
  • the ring has an L-shaped cross-section all around, locking lips 7 being formed or formed on the four corners rounded in plan view according to FIG. 1. These locking lips 7 result in detail from FIG. 3 and in their operative position with the cover from FIG. 2.
  • each locking lip 7 is integrally formed on the horizontal L-leg 8 of the locking ring 2 and extends from the L-leg 8 upwards the vertical L-leg 9 obliquely inwards to the central axis of the cover or the locking ring.
  • the locking lips 7 are essentially tongue-shaped, preferably in the form of a trapezoid, and in the embodiment according to FIG.
  • a locking lug 11 is formed on the rear or the outside 10, the tongue 7 below this locking lug 11 having an opening 12, which can be seen more clearly in FIG. 6, for the engagement of a locking projection to be described.
  • the cover 3 engages in the closed position with its lower edge 13 over the vertical L-leg 9 of the securing ring 3, in particular in a recess 14 limited between the leg 9 and the tongue 7, the Cover 3 with locking projections 15 formed on the lower edge 13 is snapped behind the locking lugs 11 of the tongues 7. As a result, the cover 3 is locked with the securing ring 2.
  • a cam 17 is formed on the container neck, namely in a number which corresponds to the number of tongues 7 of a locking ring 2.
  • four tongues 7 are used, so that four raised cams 17 are also formed on the container neck.
  • the cams 17 can be formed by the corner areas, so that separate cams 17 do not have to be formed. It is essential that the raised cams 17 increase the diameter compared to the other areas of the container neck.
  • the cams 17 are in the closed position of the cover in the region of the corners, that is to say arranged opposite the tongues 7 or according to FIG.
  • V-shaped notches 20 in the legs 8 and 9 of the securing ring 2 limit the securing ring to a film thickness at regular intervals over the circumference, so that with a corresponding widening of the locking ring 2 as a result of running onto the Aufauf ⁇ cams 17, the ring 2 breaks.
  • a total of 12 V-shaped notches 20 are provided.
  • anchor-shaped projections 18 are formed on the inner surface of the wall 4 of the cover 3, specifically a total of 4, which cooperate with corresponding closure parts 16 of the container neck.
  • the closure parts 16 are formed by thread-like ribs which, however, only extend over a small part of the circumference of the container neck.
  • a total of four rib-like projections 16 are arranged around the circumference as closure parts, which cooperate with the anchor-shaped closure members 18.
  • the rib-like projections 16 are arranged obliquely in accordance with a thread, so that when the cover 2 is rotated accordingly, the cover either moves downwards into the closed position or upwards into the open position. position is spent.
  • FIGS. 9 to 15 differs from the previously described embodiment essentially in that the lid now has a circular cross section in accordance with the cross section of the container neck, the outer contour of which is shown in dash-dot lines in FIG. 9 and is designated by 21.
  • the configuration of the locking ring, in particular the tongue 7, is otherwise as in the case of the previous embodiment.
  • on the inner surface of the wall 4 of the cover 1 there are two threads 22 as locking members and correspondingly complementary two threads ⁇ gears 23 formed on the side of the container neck as closure parts. It is not necessary here for the threads to extend over the entire circumference; rather, the threads can be broken down into four circumferential sections.
  • closure members 22 and 23 results in a screw closure with which, depending on the direction of rotation, the lid 1 can be screwed up or down with respect to the neck of the container.
  • Most thread 23 has its own projection 16, behind which the tongue 7 snaps and against which the tongue 7 blocks when the lid 1 is to be unscrewed upwards.
  • the cams 17, which can be seen in FIGS. 10 and 9, are assigned to the tongues 7 in this embodiment insofar as the securing ring 2 is widened by the tongues 7 running onto the cams 17. This results in a corresponding widening of the diameter of the locking ring 2, which due to the exactly opposite arrangement of two cams 17 is correspondingly large, so that there is a breakage of the locking ring 2 in the area of weak points 19.
  • a primary seal and a secondary seal are achieved in that a cardboard box is either glued to the underside of the lid base 3 or pinched behind a projection, which is composed of a cardboard, cardboard or thicker paper layer adjacent to the lid base, one arranged thereon PVDC layer and an aluminum foil attached to it by wax point lamination.
  • a projection which is composed of a cardboard, cardboard or thicker paper layer adjacent to the lid base, one arranged thereon PVDC layer and an aluminum foil attached to it by wax point lamination.
  • a conventional compound seal can also be used. This is a pasty mass, which stabilizes on cooling or can be hardened by microwaves.
  • a sealing washer or a sealing ring or another seal can be arranged on the lid base.
  • sealing lips can be formed in one piece, which, in the closed position, bear sealingly against the container neck or the end face of the container opening.
  • a gas-tight barrier can be achieved by applying a multilayer aluminum foil to the outside of the cover in the so-called in-mold process. In the case of a plastic cover, this barrier achieves a barrier against oxygen access to the interior of the container.
  • the aluminum foil is produced so that it is practically placed in the mold for the manufacture of the lid and the plastic material is then injected into the mold, so that the aluminum foil is firmly connected as a barrier to the lid.
  • the closure is constructed in two parts from the cover and the securing ring, but a one-piece implementation is also expedient.
  • the securing ring can be connected in one piece to the cover via thin webs.
