Definitions

  • the invention relates to a container closure for attachable tapping devices according to the preamble of claim 1.
  • US Pat. No. 4,150,771 discloses a closure of the type according to the invention.
  • the preferred field of application for this known closure is not the contamination-safe filling, emptying and cleaning (rinsing) of containers for dangerous chemicals, but the tapping of beer from kegs.
  • the two valves are designed as spring-loaded poppet valves.
  • the «beer valve is arranged concentrically in the « gas valve Erasmus
  • the plate of the «gas valve» is fixed tightly in the upper end of the riser pipe and has a central hole that forms the seat of the «beer valve».
  • the seat of the “beer valve” is formed by a conical lower ring surface of an inwardly projecting flange part of the outer closure housing.
  • the valve springs are coil springs. Due to the design, the «gas valve» spring not only has to support the valve but also the riser. Due to the structure, this construction has many individual parts and is quite complicated.
  • the aim of the invention is to provide an optimally contamination-proof container closure for filling, emptying and washing the container, which at the same time is so simple and cheap with optimal operational safety that it can also be used in particular as a one-way closure.
  • the closure 10 comprises four parts, namely a housing 12, the main part of which resembles a cupcake mold placed upside down, a cover 14 having a cover flange 14A with a central opening 14B, a valve body 16 and a spring 18 surrounding the latter.
  • the valve body 16 has a stem part 20, which is surrounded by the spring 18, and a plate 22 as a sealing element.
  • the valve disk 22 lies sealingly on the underside of a radially inwardly projecting ring flange 14C of the cover 14.
  • the valve plate 22 forms a dynamic seal under the pressure of the spring 18, which in turn is supported with its lower end on an annular wall rib 24 which extends radially inwards.
  • a downwardly directed pipe socket 28 of the housing 12 is in communicating connection with the inner chamber 200 having the upper opening 14B.
  • the housing pipe socket 28 is integrally connected at its upper end to the inner edge of the annular rib 24, which in turn protrudes radially inward from the cylindrical inner wall part 30 of the cupcake mold forming the main part of the housing.
  • the inner wall part 30 merges at its lower outward curved end into the outer wall part 32 integral with it, as a result of which an upper open outer chamber 34 is formed between the two wall parts.
  • the outer region of the cover flange 14A which is loaded elastically upward, covers the outer chamber 34 in a sealing manner and is normally stopped at its outer edge by a retaining ring 36.
  • a number of holding members secure the cover 14 in its position inside the cylindrical wall part 30 by engagement with a number of correspondingly provided holding beads 42 on the inner surface of this wall part.
  • the cover pipe socket 40 forms the outer wall of the inner chamber 200.
  • the flange 14A formed from flexible elastic material seals the outer chamber 34 of the housing 12 and forms a flap valve.
  • Polypropylene is particularly well suited for the production of the flange 14A. Thanks to its elastic flexibility, the flange 14A can be bent downwards by means of suitable, spaced-apart tines of a tapping device designed to be placed on the edge part of the housing 12 surrounding the cover 14, as will be explained in more detail below.
  • closure 10 in the embodiment described in Figures 1 and 2 can be attached to any type of container, and various attachment means can be used to prevent accidental leakage or displacement.
  • annular projection 50 which is provided on the upper region of the outer wall part 32 of the housing 12 and which can engage with a flange provided on the container can be used as such a fastening means.
  • a flange 52 which is provided at the upper end of the housing 12 and extends radially outwards, is suitable for extending over the opening of the container.
  • Other fastening means such as a simple friction fit, a clamping or pressure ring, or also thermal or induction sealing or the like can be used.
  • a riser pipe 54 is connected to it, which extends into the vicinity of the container bottom and dips into a depression, preferably provided in the container, for a liquid sump.
  • the riser pipe 54 is advantageously installed in the container together with the closure 10, to the housing pipe socket 28 of which it can be fastened by means of the retaining bead 56.
  • the riser pipe 54 can also be previously inserted into the container in the required position in another suitable manner.
  • valve plate 22 In use, the end face of the valve plate 22 must be lifted sufficiently far from the lid opening 14B to allow a desired amount of liquid to pass between the valve body 16 and the lid 14. At the same time, the flap valve formed by the outer area of the cover flange 14A must be pushed down in whole or in part in order to allow the tapped volume of liquid in the container to be replaced by air.
  • the windows 60 there are eight such windows 60; they allow the drainage of the housing 12 and thus reduce the risk of contamination of the liquid. These windows 60 also serve to allow the flushing water to be sprayed into the container, in particular after its contents have been completely emptied.
  • the windows 60 are formed as elongated slots in the axial direction and are arranged at the lower end of the housing interior 34 in such a way that rinsing water flowing out of them is open on all sides the inner wall of the container is directed.
  • the valves return to their closed positions. Empty containers can be thrown away or refilled, and partially empty containers can be opened again by repeating the tap procedure.
  • a modification of the embodiment according to FIGS. 1 and 2, not shown in the drawings, can provide that, when the flange 14A is pressed down, the slots 60 can be cleaned by wiping off disturbing or clogging or contaminating particles. This is particularly useful in those cases where certain chemicals cause such interference.
  • the slots would be located just below the zone in which the outer circumference of the flange 14A in the closed position rests against the inside of the outer wall part 32, this region of the flange 14A being able to be equipped on its circumference with extension elements which, when assembled of the closure extend into the slots provided in the new position mentioned above and would thus also form an adequate seal.
  • FIG. 3 shows a further embodiment of the closure according to the invention, designated here by reference number 80.
  • the inner wall part 90 of the housing delimiting the inner chamber 200 is here of the same internal width as the housing pipe socket 98 projecting downward from the main housing part, so that a continuous cylindrical inner wall part 98 is thereby formed, which surrounds the passage 96.
  • the central valve which controls the passage of liquid chemicals from and into the container, consists of the slit valve, which together forms a slot valve and extends radially inward from the upper end edge of the inner wall part 90, which is formed integrally with the housing 82, of tongues 84B of the lid part 84, while the radial outward flange 84A of the cover part 84 closes off the annular space 94 formed between the housing outer wall part 92 and the inner wall part 90 of the tubular piece 98 surrounded by the latter at its upper end. While in the embodiment according to FIG.
  • the inwardly directed tongues 84B of the cover part 84 are individually fastened to the upper edge of the inner wall part area 90 by means of hinge straps 84C, there could also be a single undivided valve flap, which is connected to the above-mentioned upper edge on the right or left by means of a suitable joint connection of the cylindrical portion 90 could be hinged.
  • the tapping device (not shown) suitable for placement on the housing 82 for use with the closure 80 would be brought into the correct aligned position with the central flap valve 84B by means of pins 86 protruding on the upper side of the outer flange region 84A.
  • FIG. 4 shows a special embodiment of a tap 100 together with a closure according to FIG. 1.
  • the tapping device 100 restricts the connection to precisely defined, safe routes.
  • the arrangement may have a stand (not shown) in which the container 101 is positioned to be aligned with the tapping device 100, whereupon the latter is brought into pressure contact with the closure 10, so that a tight connection is created and the various Operations can run.
  • the necessary organs are installed in the tapping device 100 in order to press the closure valves down and thus to open them.
  • These organs can be designed in such a way that a plurality of organs opening the valve can come into operation simultaneously when the closure 10 and the tap device 100 are connected forehead to forehead.
  • the organs can also be operated independently of one another.
  • the underside of the sealing ring 102 of the tapping device 100 is intended for sealing contact with the inner flange 14C of the cover, which serves as a valve seat for the central valve of the closure 10, and ensures that the two flows, one of which is a flow of the liquid product the interior of the container and the other a stream of either product to be filled into the container or rinse water or air are isolated from each other.
  • a guide piston 104 is extended from a passage 118 which receives it and has an annular cross section of a cylinder with the lower frustoconical piston end and is pressed with the end face of said piston end against the upper end face of the valve plate 22.
  • the diameter of the end face of the frustoconical end of the piston 104 is dimensioned such that this piston end can pass through the central opening 14B of the cover 14.
  • downward tines or pins 106 also travel downward with the piston and encounter the outer portion of the cover flange 14A, which they bend downward in the manner shown in FIG. 4. As a result, air can flow through the housing space 34 and the windows 60 into the container for pressure equalization. Rinsing water can also be poured into the container in this way.
  • Openings 108 are provided in a suitable manner in the lower end face 110 of the tapping device, through which openings or Flushing water from the chamber wall enveloping the interior 112 of the tapping device can reach the outer chamber 34 of the closure 10 when the Kiappenventii 14A is open.
  • a connection piece 114 is provided, to which the hose of a water or air line can be connected.
  • the liquid chemical in the container is made available with the aid of a suitable suction source (not shown), which is connected to a connecting piece 116, which in turn is mounted in the wall of the cylinder surrounding the passage 118 and brings a line of the suction source into the passage 118 in free connection , tapped.
  • a suitable suction source (not shown)
  • a connecting piece 116 which in turn is mounted in the wall of the cylinder surrounding the passage 118 and brings a line of the suction source into the passage 118 in free connection , tapped.
  • the main advantages of the above-described embodiments of the arrangement according to the invention for removing liquid from a container include the possibility of rinsing or spraying out the emptied container without first having to uncouple the container from the tapping device and open it by removing the closure.
  • the tapping of hazardous liquid chemicals is accomplished without interfering with the flushing or spraying, and ventilation is provided by bending the flange portions 14A downward.
  • a rinsing water reservoir (not shown) of sufficient capacity is advantageously connected to the tap and water is removed from it during rinsing.
  • the user can actuate a valve mechanism of the accumulator which allows a certain amount of water to be introduced or sprayed into the container.
  • the water collecting at the bottom of the container can be sucked off again through the passage 26 of the pipe socket 28 of the closure 10.
  • the entire arrangement can be equipped for automatic storage and refilling.
  • the user again actuates a lever (not shown), as a result of which the piston 104 also returns to its upwardly retracted position in the cylinder surrounding the passage 118, so that the tapping device can now be lifted off the closure again.
  • the container is preferably mounted in a rack, this is not necessary and the tapping device could also be attached to the container by means of internal or external screw connections provided for this purpose, or a flange of a flexible Reike-type outlet nozzle can be connected or a locking device can be used inside the tap.
