Definitions

  • the invention relates to a plastic closure for filling openings of containers, such as barrels, barrels, canisters, cans or the like.
  • U-shaped base with a sleeve-shaped inner leg and a sleeve-shaped outer leg, in which the base with the The outer leg engages around the tube extension of the container forming the filling opening and engages with the inner leg in the latter, in which the base is provided with a bulge which engages behind a projection, an edge or the like of the tube extension, and in which the outer leg of the base is provided by means of an L -shaped retaining ring is firmly encompassed, which rests with an annular disk-shaped area on the upper ring surface of the base and is fixedly connected thereto.
  • Such a closure is known from US-A-4,632,282. With this retaining ring, the hold of the base on the filling opening of the container, which is designed as a tube extension, is improved.
  • the closure has a pouring spout, which is connected to the base via a bellows. In this way, the pouring spout can be brought into an inserted starting position and into an extended pouring position. The However, the closure is not clearly held in the starting position and is not tightly closed.
  • the retaining ring extended to a kind of cap clearly seals the closure in its initial position.
  • the tubular or conical approach between the annular disc-shaped area and the top surface with its small wall thickness is a kind of predetermined breaking point, so that the top surface can be easily removed without holding the Interfering with the closure on the filling opening of the container.
  • the retaining ring fulfills both functions - holding the closure and sealing the closure.
  • the application of the closure to a filling opening is facilitated in that the inner leg of the base on its outer jacket and / or the outer leg of the base on its inner jacket have an undercut for engaging behind an edge of the filling opening.
  • the hold can be further improved in that the inner leg of the base is supported on a support ring inserted from above, or in that the inner leg of the base is supported on a support ring inserted from below, it being provided in each case that the support ring consists of harder plastic than the base.
  • the support ring is fixed in a simple manner in that the inner leg has retaining elements engaging behind the support ring.
  • a closure made of plastic is shown in the delivery state in the top view and in broken section. It is delivered in this assembled state, and in this state it remains during insertion into the filling opening of a container until it opens.
  • FIG. 4 shows the closure after removal of the horizontal cover surface 17 of the retaining ring 12 of FIGS. 1 and 2 serving as a sealing cap and in the pulled-out state and after opening the same.
  • FIG. 4 shows the ring-shaped base 1 of the closure equipped with a U-shaped profile, to which a spout 3, which is designed as a valve housing and a limited rotatable plug, is connected via an extended, flexible and essentially conical bellows 2 4 encloses.
  • the plug is closed at the top by a cover plate 5 resting on the free end face of the spout 3, and at its lower end the plug is provided with a groove 7 into which the lower end face of a collar 6 formed by a conical tapering of the spout 3 enters .
  • the chick 4 is axially fixed rotatably in the spout 3 and can be rotated from its closed position into the open position shown, in which its passage 8 with the outlet 9 of the spout coincides.
  • the outlet 9 is kept so long that conventional liquids are dispensed in a practically constant and not constantly changing direction.
  • an inner leg 10 which can be inserted into the filling opening of a container, which can be designed, for example, as a short tube extension, pushed out of the wall of the lid of a container, the outer end of which has a fixing edge forming, inward-down, or, as for the embodiment, folded outward-down.
  • the base 1 has an outer leg 11 on which such a short tube extension of the container, which forms the filling opening, is able to enclose and thus intensifies the connection between the base 1 and the filling opening by holding the tube extension of the filling opening between the inner leg 10 and the outer leg 11.
  • the axial hold is ensured here by the inner leg 10 having a conical end on its outer jacket with a bulge, an undercut or the like being arranged in the known manner when the end of the tube extension of the filling opening is folded in, while in the exemplary embodiment the outer leg is turned over
  • the inner jacket of the outer leg 11 widens conically in its end region at the ends of the pipe lugs and is equipped with an inwardly projecting bead, the upper, steep flank of which forms an undercut which, when pressed onto the pipe shoulder, engages behind its free end which is folded outwards and downwards .
  • the outer leg 11 is designed in such a way that on the one hand it prevents the inner leg 10 from evading, while on the other hand it is able to adapt to deformations of the filling opening or of the tube attachment.
  • This binding is additionally reinforced by a retaining ring 12, which is designed with an L-shaped profile and surrounds the outer leg 11 firmly and supportively with a tubular region 13.
  • Another Stiffening is achieved in that the retaining ring 12 is made of stiffer, less elastic or harder plastic than the base 1, bellows 2 and grommet 3.
  • the holding ring 12 is at the same time also the carrier of the actual sealing cap: from the inner edge of the ring-shaped area 14 of the holding ring 12, a very short and thin-walled tubular, possibly also conical, extension 16 extends in a step-like manner upwards and is through a horizontal cover surface 17 is closed, which lies directly above the chick and its handle after assembly of the closure, so that the desired low height is achieved.
  • the tubular extension 16 can also be formed by a tear tab; on the other hand, it is advisable to constrict a corresponding ring area of the cover surface 17 by means of a groove in the event that a pull tab is desired in such a way that a strip that ends in a handle and is easy to separate is produced.
  • the horizontal cover surface 17 in the area of the tubular extension 16 can be easily separated from the annular disk-shaped area 14 of the retaining ring 12 by means of a tool, for example a knife, a screwdriver or the like, and the tool then moves along the tubular extension 16, the top surface 17th so severed that it cannot be reattached as part of fraudulent manipulations after the package has been opened.
  • a tool for example a knife, a screwdriver or the like
  • the plug of the illustrated closure is handled in a known manner. Its cover plate 5 is provided for better guidance of the legs 20 of a metal bracket 19 with annular collars 18, and the legs 20 of the metal bracket 19 are conical at the free end to facilitate insertion into a collar and the cover disk 5 penetrating hole and are performed by a the conical area following paragraph after insertion.
  • a relatively firm fit of the stirrups can be achieved by the region of the legs 20 located within a hole when the stirrup is pulled out being adapted to the diameter of the holes with a tight fit and optionally additionally knurled slightly, while the diameter of the legs 20 is relative to the yoke of the metal stirrup 19 slightly reduced.
  • a defined range of rotation of the plug is achieved if a pin 21 serving as a stop is arranged in the pivoting path of the inwardly projecting ends of the legs 20;
  • the eccentric arrangement of the metal bracket 19 shown in connection with the width of the appropriately rectangular pin 21 allows a defined pivoting angle of 90 ° to be maintained.
  • the pivoting movement required to open and close the closure is illustrated by a double arrow 23 of FIG. 3, while an arrow 24 allows the respective position of the passage 8 of the plug 4 and thus the state of the closure to be recognized.
  • the assembly of the closure on the container can be simplified and mechanized in that a cam 22 provided on the retaining ring 12 is brought into a predetermined position during assembly.
  • the retaining ring 12 is applied and before it is welded, the latter is rotated such that the cam 22 is in a predetermined relation to the angular position of the Spout 9 of the nozzle 3 is so that it can be ensured that this is in the predetermined position to the container when the closure is mounted.
  • the base 1 and the retaining ring 12 can also be equipped with at least one pair of interlocking elements, for example a pin or a hole or groove, in order to also necessarily achieve corresponding positions between the essential part of the closure and the cam 22 of the retaining ring 12.
  • connection between the base 1 of a closure and a tube extension of the container surrounding a filling opening is not limited to the shut-off valve shown.
  • the bellows 2 can end with a threaded bushing for receiving a closing screw cap, or the base 1 can be equipped directly with a corresponding threaded bushing.
  • the intensive contact by means of the U-shaped profiled base 1, which encompasses the tube extension of the container on both sides, in connection with the retaining ring 12, which encompasses and supports it, is made of suitably harder plastic.
  • support rings 24 made of stiffer and less elastic material, which can be inserted into the inner leg 10 from above or from below, as is indicated in the left half section of FIG. 4.
  • Such a support ring 24 is expediently held in its position after assembly by special holding elements 25 until after the closure has been applied, a tight fit is ensured by the resulting tension.
  • these holding elements can engage behind the support ring 24, but they can also be achieved by a snap-in tongue and groove connection, it not being necessary to provide circumferential grooves and circumferential projections.
  • the support ring 24 In the case of the support ring 24, especially if it is divided at a circumferential point, it would be sufficient to provide the inner leg 10 with a circumferential groove and the support ring 24 with short projections engaging in them. which should be provided at least on both sides of the subdivision and opposite it.
  • the lighter shape In the case of the holding element shown throughout, the lighter shape is recommended because of a subdivision into individual, short, claw-like holding elements at a distance.
  • a support ring inserted from above can be used, which could be made of harder, more resistant plastic or even of metal.
