Definitions

  • the invention relates to an environment-sealed arrangement for tapping liquid chemicals from a container, and in particular, for tapping liquid chemicals which are harmful to health, such as acids, cancer-causing liquids of all kinds and pesticides.
  • U.S. Patent No. 4,150,771 is the most notable of the publications cited because it discloses a two-way valve closure that can be used when tapping beer from kegs. However, such a closure is when connecting a tap not usable to draw off a liquid chemical flow from the container at the same time and at the same time allow air to flow into the container, and at another time, with the extraction device still connected, to spray flushing water into the container and at the same time to draw it out of it again.
  • the closure of U.S. Patent No. 4,150,771 is capable of being connected to several different coupling devices by the presence of hooks or the like projections in order to carry out separate operations.
  • the invention further aims to limit the tapping of the liquid so that specifically adapted tapping devices must be used for this purpose, both the container and the tapping device to be coupled to its closure both being largely free of impurities after the tapping has been completed or completely emptied.
  • Another purpose of the invention is to ensure a complete automatic reclosing of the container after each tapping when the tapping device is removed, regardless of whether the container was only partially or completely emptied.
  • the invention aims to achieve the stated object and to achieve the stated purposes using the least expensive means possible, which nevertheless deliver the desired results.
  • valve system of the container closure is opened by suitable organs of the tapping device placed on the closure, which forms a whole against the environment, and closes automatically as soon as the tapping device is separated from the closure again.
  • a rigid closure housing the main part of which is preferred a cupcake mold with its open side facing upwards, with a preferably cylindrical inner wall part and a surrounding outer wall part which is inclined towards the lower end and adjoins the inner wall part in the bottom region, a passage space being formed in the interior of the inner wall part, which is directed upwards by an in a housing cover provided outlet valve is closed and continues downward in a downwardly protruding from the main part of the housing pipe socket to which a riser pipe, preferably reaching to the bottom, can be connected; while the annular space located between the outer wall part and the inner wall part of the housing is closed at the top by an inlet valve also provided in the housing and is connected at the bottom by windows or slots provided in the housing outer wall part to the interior of the container.
  • water or another cleaning agent can be introduced into it through the open inlet valve, e.g. can be sprayed in, and the cleaning liquid collecting at the bottom of the container can be sucked off again through the open outlet valve via the riser pipe and the inner housing passage by means of a suction pump connected to the tap.
  • the tapping device is also designed such that in it the flow of the media flowing into the container is completely separated from the flow of the liquid tapped from the container.
  • the container closure according to the invention is advantageously designed so that it can be attached to the container in place of the most common ordinary closures.
  • the three most common closures used in the United States are a 63mm screw cap, a REIKE-type pliable snout, and a two-inch NPT bung.
  • Another important feature of the invention provides a probe which can be retracted into the closure, into which a tap piece can be inserted from above, so that the probe can be fully extended into the container and the tap flow is preferably sucked off through the inner passage of the tube piece, while the pressure equalization takes place through air, which remains through the annular space between the outer wall of the pipe section and the inner wall of the probe.
  • valve system In order to meet the criteria that must be observed when pouring pesticides or the like openly, it is considered essential that the overall arrangement include a two-way valve system. In order to be easily accessible, this valve system should also be able to be connected to a tap which only has to be connected in one plane, the preferred plane being that of a face-to-face connection, without requiring that the two be connected to one another must take to each other within a full angle of 360 0 any particular position devices.
  • FIGS. 1 and 2 show a first embodiment of a closure which can be inserted into a container according to the present invention with its parts in an exploded arrangement or assembled.
  • the closure 10 comprises four parts, namely a housing 12, the main part of which resembles an upturned cup cake form, a cover 14 having a cover flange 14A with a central opening 14B, a valve body 16 and finally a spring 18 surrounding the latter.
  • the valve body 16 has a shaft part 20, which is surrounded by the spring 18, and a cap 22 as a sealing valve disc.
  • This valve disc 22 lies on the underside of an inner flange 14C of the cover 14 which projects radially inwards at the upper end of a cylindrical cover stub 40.
  • the cap 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.
  • 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, outwardly curved end into the outer wall part 32 which is integral with it, as a result of which an inner or passage space open at the top and elastically loaded upwards is formed between the two wall parts.
  • the outer / area of the cover flange 14A which extends radially outward at the upper end of the pipe socket 40, covers the interior 34 in a sealing manner and is normally stopped at its outer edge by a retaining ring 36.
  • a number of holding members 38 on the outside of the cover pipe socket 40 secure the cover 14 in its position in the interior of the cylindrical wall part 30 by engagement with a number of correspondingly provided holding beads 42 on the inner surface of the wall part.
  • the fleece 14A formed from flexible elastic material seals off the interior 34 of the housing 12 and thus forms a flap valve; polypropylene is particularly suitable 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 plug-on 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, as will be readily apparent, be attached to all types of containers, 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 can engage with a flange provided on the container can be used as such a fastening means.
  • a radially outwardly extending flange 52 provided at the upper end of the housing 12 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 is immersed in a liquid sump preferably provided in the container.
  • 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.
  • the end face of the valve disc 22 must be 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.
  • the flap valve formed by the outer region of the cover flange 14A must be pushed down in whole or in part in order to permit the replacement of the drawn volume of liquid in the container by air.
  • These windows 60 are spaced apart from one another over the circumference of the outer wall part 32. For example, there may be 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 40 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 they flow out of them Rinsing water is directed towards the inner wall of the container on all sides.
  • the valve body After the end of the emptying and washing process or also after the end of a partial emptying followed by uncoupling the tapping device, the valve body returns to its closed position. Empty containers can be thrown away or refilled, and partially emptied containers can be opened again by repeating the tap procedure.
  • Refilling of the containers can be done using the same closure 10 according to the invention, or this device can be replaced with a new one if necessary. If necessary, reuse of the device can be prevented by installing a ball or flap shut-off valve.
  • FIGS. 1 and 2 Possible modifications of the embodiment of the closure shown in FIGS. 1 and 2 include e.g. the omission of the flapper valve provided for cooperation with the interior of the housing 12 and formed by the outer region of the cover flange 14A.
  • a compressible, chemical resistant foam seal body could be placed in the interior 34 between the inner wall portion 30 and the outer wall portion 32 of the housing 12 so that this seal body normally covers the windows 60, but when pressed together Allow air or water to enter through these openings.
  • a further modification, not shown in the drawings, of the embodiment according to FIGS. 1 and 2 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 periphery of the flange 14A in the closed position lies against the inside of the outer wall part 32, this region of the flange 14A being able to be provided on its periphery with extension elements which, when assembled of the closure extend into the slots provided in the new position mentioned above and would also form an adequate seal.
  • FIG. 3 A second embodiment of the closure according to the invention is shown in Fig. 3. Also in this embodiment, as in the previously described modification of the first embodiment, no flap valve formed by the outer region of the flange 14A is used.
  • vertical that is to say axially extending, automatically closing slots are provided in the outer wall part 72 or also in the base part, either under the pressure of air or water or by special means provided on the tapping device Actuators are opened, ie the tapping device is modified so that it interacts with the slots 71 shown in FIG. 3.
  • FIG. 4 shows a further embodiment of the closure according to the invention, designated here by the reference number 80.
  • the cover the valve body and the spring are omitted.
  • the inner wall part of the housing is here of the same internal width as the housing pipe socket 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 jointly forming a slit valve, which extends radially inward from the upper end edge of the inner wall part 90 formed integrally with the housing 82, tongues 84B of the cover part 84, while the radial outward flange 84A of the cover part 84 closes the between the housing outer wall part 92 and the inner wall part 90 of the tubular piece 98 surrounded by this 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, a single undivided valve flap could also be present, which by means of a suitable articulated connection on the right or left at the said upper edge of the cylindrical portion 90 could be hinged.
  • the tapping device (not shown) for use with the closure 80 to be placed on the housing 82 would be brought into the correct aligned position with the central flap valve 84B by means of pins 86 protruding from the top of the outer flange portion 84A.
  • a tapping device 100 comprises a connection arrangement which is especially designed for connection to a closure in the first embodiment 10 shown in FIGS. 1 and 2.
  • This tap device 100 limits the connection to only a valve-provided section, a valve body and a housing, a ventilation valve, a water supply line and a connection piece for a discharge pipe.
  • the arrangement has yet another peculiarity, namely a stand (not shown) in which the container 101 can be placed so that it is aligned with the tapping device 100, whereupon the latter is brought into pressure contact with the closure 10 so that it is tight and can be subjected to the various operations described.
  • the necessary organs are installed in the tapping device 100 in order to press the flange valves down and thus open them. Their construction can be carried out in such a way that a plurality of organs opening the valve can come into operation at the same time with a front-to-front connection of the closure 10 and the tapping device 100. On the other hand, the organs can also be operated independently of one another.
  • the underside of the sealing ring 102 shown therein is intended for sealing engagement with the inner flange 14C of the lid serving 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 inside of the container and the other are a stream of either product to be filled into the container or rinse water or duct.
  • a guide piston 104 is extended from a receiving passage 118 of annular cross section of a cylinder with the lower frustoconical piston end and pressed with the end face of the said piston end against the upper end face of the valve disk 22.
  • downward / serrations or pins 106 also move downward with the piston and encounter the outer portion of the cover flange 14A, which they bend downward as shown in FIG. This allows air to flow through the housing interior 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, through which air or rinsing water from the chamber wall enveloping the interior 112 of the tapping device can get into the interior 34 of the verder 10 when the flap valve 14A is open.
  • a connection piece 114 is provided in / the chamber wall containing the interior 112, to which the hose of a water or air line can be connected.
  • the liquid chemical in the container is by means 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 ring passage 118 and brings a line of the suction source into the ring 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 ring passage 118 and brings a line of the suction source into the ring 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 also accomplished without interfering with 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 reservoir which allows a certain amount of water to be injected 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), which also causes the piston 104 to return 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 be used inside the tap.
  • the probe is preferably used when connecting the Ab dispensing device extended to the container closure.
  • Such a closure 300 with a retractable probe 300A, 300B is shown in one piece in FIGS. 6 to 11 and made of plastic, it not requiring any special springs. Its structure is therefore largely simplified.
  • the improved probe closure 300 is preferably made in one piece by injection molding and folded back into itself in the warm state for ease of manufacture; it has an upper or outer, relatively thick head part 300A and, in the extended state, it is lower, ie lower, and in the retracted state it is located inside the head part and is thinner and correspondingly more flexible ascending pipe part 300B; in Fig. 6 both parts are shown with the probe retracted.
  • the head part 300A has hanging ears or retaining pins 302 protruding on its inner wall, by means of which the riser pipe part 300B is retained in the interior of the head part 300A in the folded state with the aid of corresponding openings, in particular slots 304.
  • this probe 300 is a special device for introducing liquid through the lower end of the extended flexible riser valve 300B, which comprises a membrane 306 in the bottom of the probe and a cylindrical ejection member 308.
  • this inlet member 308 is pushed into the interior of the container 310 (FIG. 6), for example by a fixed connection to the lower end of the piston 104 of the tapping device 100, whereby the riser tube portion 300B of the probe 300 by inward bending the upper fold edge of the riser tube portion 300B when suspended, as indicated by chain lines in FIG the eye drop ears 302 is detached and extended from the head portion 300A and extended towards the bottom of the container into the container.
  • the inlet hole for the entry of a dangerous liquid chemical into the extended riser tube part 300B can be produced by the fact that the lower, possibly sharp end of the ejection member 308 pierces or cuts a hole in the membrane 306.
  • the bottom of the probe may include a piston mechanism for sealing a fluid leak.
  • Another type of sealing against liquid passage can consist of a valve in the bottom of the probe, which is opened by contact with the bottom of the container.
  • the arrangement of the retractable probe in the closure 300 permits critical two-way flow; when the probe 300B is fully extended, as shown in FIG. 10, the chemical container contents can be tapped directly by sucking into the cylindrical probe ejection member 308, shown in dash-dotted lines, designed as a suction tube, the required ambient pressure equalization inside the container being achieved by means of the between the Outside surface of the cylindrical outer member 308 and the inner surface of the wall 312 of the fully extended probe part 300 B located passage space 311 of inflowing air takes place.
  • water or other liquid can pass through the openings 303 in the head portion 300A of the probe. and the passage space 311 is filled into the interior of the container and rinsing water is sucked out again through the hollow interior of the cylindrical ejection member 308.
  • the probe has an alternate slot-and-plug arrangement in which a series of plugs on one side of a hinged band is sealingly inserted into a series of slots on the other side of the band when the probe is withdrawn when pressure is applied while the plugs are removed from the slots when the riser tube 300B is extended into the container.
