Definitions

• the invention relates to a packaging container for receiving a flowable product, which consists of a stored in a rigid envelope bag with closable outlet bung and this associated opening, the outlet bung with a bung neck for receiving egg nes closure element and with a connecting element for attachment to the packaging container or is provided on the product container arranged therein.
• bag in box packaging in which, for example, liquids located in plastic bags are stored in U cartons, the cartons as packaging containers being provided with closable outlet openings which are provided with the plastic bags work together.
• the advantage of such packaging is, inter alia, that only the liquid-absorbing bags have to be made of a physiologically perfect, harmless material, without this material simultaneously having to take on the function that packaging normally has to have, ie what the strength, the portability, manageability and the like. concerns. This function is taken over by the outer carton, which can be made from corrugated cardboard, for example, and from recovered old paper was made.
• the closures of this type of packaging represent a particular problem, which generally have to meet a number of requirements.
• the packaging simply has to be convertible from pure transport closures into metering closures, such as metering taps or the like, it has to be inexpensive to manufacture and, in particular, easy to handle in order to achieve the highest possible consumer friendliness.
• closures must of course be leakproof, they must be reliable and allow the removal of the respective packaged products in a simple manner, as well as, if necessary, make it possible to exchange liquid containers within a given packaging.
• the object of the invention is therefore to create a solution which meets these diverse requirements, i.e. which is in particular simple and economical to manufacture and which enables wide use.
• the bung neck has at least two, preferably four parallel, opposite, outwardly pointing straight bottles. Chen for positioning the bung.
• This special bung design makes it possible to secure the bung neck against rotation in any case, namely by contacting corresponding recesses in a surrounding cardboard box, it simplifies handling, enables screw closures as well as plug closures and the like. At the same time, a very low overall height is possible, which means that e.g. in the case of a pre-assembled packaging, the closure protrudes very little compared to the other packaging.
• the invention provides that the straight surfaces are arranged as square surfaces on the inside and / or outside of a part of the sheet pile wall.
• At least one recess is provided on the outer circumference of the sheet neck edge
• the invention also provides that the bung neck merges into the flange of the bung by means of an outwardly facing bevel, the bevel being used as a centering or insertion surface when the bung is inserted into the corresponding packaging elements.
• the sheet pile flange can be designed as a thin-walled welding flange for connection to the packaging elements, in particular the welding flange can be used for fixing liquid-tight fastening of the bag receiving the liquid.
• the invention also provides that an at least regionally overlapping the free end of the bung is provided with locking cams for engaging over the upper free edge of the bung neck with a pouring spout which is equipped with an end cap provided over a notch as a predetermined breaking point .
• a drainage tap with engagement areas inside the sheet flange is provided as the closure element with fixing cams for engagement in the corresponding recesses on the sheet neck.
• the drain valve is equipped with a handle bar on its axis of rotation.
• FIG. 1 is a plan view of a bung according to the invention
• FIG. 3 shows a closure element with a pouring spout
• Fig. 4 shows a closure element with a tap
• FIG. 5 shows a top view of a tap according to arrow V in FIG. 4.
• a bung generally designated 2 is provided, which is formed by a bung neck 3 and a flange 4, the flange 4 being designed as a welding flange, ie a plastic bag 5 for example attached liquid-tight, ie welded.
• the bung 2 has a circumferential fixing flange or collar 6 and outwardly facing straight surface areas 7 between the collar 6 and a transition bevel 8 to the welding flange 4, the transition bevel 8 serving as a centering or insertion bevel at the same time.
• the straight surfaces 7 form an outer square and are used for the torsion-proof installation of the bung 2 in the packaging container 1.
• the neck 3 of the bung 2 has at its upper free end 9 an outwardly facing clamping bead 10 with recesses 14 and an inner clamping groove or a correspondingly designed clamping edge 11 on.
• the inner surface of the neck 3 is also equipped with a square, which is shown in dash-dotted lines in FIG. 1 and bears the reference number 12, the round inner corners have the reference number 13.
• recesses 14 and 15 are shown in FIG upper circumferential clamping bead 10 or in the collar 6, which also serve to secure the rotation of elements corresponding to the bung 2.
• FIG 3 shows a closure element, generally designated 16, with a pouring spout 17, which has a head cap PE 18 is equipped, which can be removed by a predetermined breaking point 19 by the consumer.
• the closure element 16 engages around the bung neck 3 from the inside out and engages behind the clamping edge at the free end of the bung neck 9.
• Another type of closure shows a dosing tap 20 which engages inside the bung neck 3 and engages a kind of snap / snap connection 21 behind the edge 11 inside the bung neck.
• cams 22 can be provided which engage, for example, in the recess 14 in the upper free edge 9 of the bung neck 3.
• the tap is provided with an actuating handle, which is designed as a thin web 23 and represents the respective position of the tap to the user via inclined surfaces 24.
• the cock In the position shown in FIG. 5, the cock is in the open position, the front pouring opening 25 is free.
• closure and shut-off elements can also be designed in a different way u. Like. more.
