Abstract
ABSTRACT OF THE INVENTION
An emptying device for bag-in-box packs, includes functional components molded integrally with the container spout or bung, which is welded to a plastic bag of the bag-in-box pack, during its production, whereby after the container has been filled, the bung can be closed by pushing a closure element in the form of a valve body into the spout. This is achieved by providing a valve body with a cross-section that changes longitudinally of the bung on both sides of the emptying spout, and is sealingly mounted for rotation in a corresponding widening or narrowing of the cross-section of the bung. The resulting emptying device is a two-part system in which the outlet tap is integrated in the bung, and provides for particularly easy handling during emptying, and guarantees exact levels of filling.

Description
2~ Z53 KW111389/903.1.066 D 8847 DEVICE FOR EMPTyING BAG-IN-BOX PACKS
BACKGROUND
1.0 Field of the Invention:
This invention relates generally to devices for emptying packaging containers, and more particularly bag-in-box packs.
2.0 Discussion of Related Art:
The production of bag-in-box packs for liquids or paste-form products is plagued by the problem that simple closure caps or stoppers, although inexpensive to make, do not offer the convenience required by consumers for emptying such containers in the same way as more elaborate emptying attachments. Unfortunately, the latter are expensive to manufacture and much more costly than non-reusable packs in the form of bag-in-box packs. In addition, the outlet taps and systems presently in use are made up of too many parts (frequently bungs, adapter, outlet tap) and are therefore too expensive for the system.

Unfortunately, the latter are expensive to manufacture and much more costly than non-reusable packs in the form of bag-in-box packs. In addition, the outlet taps and systems presently in use are made up of too many parts (frequently bungs, adapter, outlet tap) and are therefore too expensive for the system.

An object of the present invention is to provide simple emptying devices, which are particularly suitable for bag-in-box packsj and of which the functional components are designed , ,:,. :, in such a way that they can be molded integrally with the container spout or bung during its production so that, after ~ -- z0~)3Z~;3 the container has been filled, the spout can be closed simply by pushing a closure element in the form of a valve body into the spout.
According to one embodiment of the invention, the solution to this problem provides a valve body with a cross-section which changes in the longitudinal direction of the bung or stopper on both sides of the emptying spout, and is sealingly mounted for rotation on the bung in a corresponding widening or narrowing of the cross-section.
The advantage of the invention is that the emptying device consists of components integral with the bung of the bag-in-box pack and requires only a single compact closure element, which on completion of the filling process, is pushed into the spout or bung from outside. Because the emptying device is in the form of a valve body, it can be used for exact dosing during filling of the container and as a closure after the container has been emptied.

DETAILED DESCRIPTION OF_THE INVENTION
The embodiments shown in the drawings are of emptying devices 1 for packaging containers comprising a plastic bag 2 for liquid, free-flowing or paste-form products, in the form of bag-in-box packs comprising an outlet bung 5 of a thermoplastic or other plastic which is arranged on a side wall or intermediate ~ 1 3 of the container, preferably near an edge 4 (see Figure 5) of the container, and which is sealingly closed by an end closure element 6. Bag-in-box packs such as these typically consist of a plastic bag 2 and an outer case 2a (Figures 5 and 6) of corrugated cardboard, for example, or other suitable material.
In all the illustrated embodiments, the outlet bung 5 welded to the plastic bag 2 comprises an integral emptying spout 7, which projects laterally outward and which is designed to be selectively opened or closed.
As shown in Figures 1 and 2, the closure element 6 comprises an integral, substantially spherical valve body 12 which is designed to be pushed into the bung 5 from outside, and of which the substantially spherical to oval, rounded cross-section changes in the direction of the longitudinal axis 23 of the bung 5 on both sides of the emptying spout 7. The ... .
valve body 12 is mounted sealingly for rotation in the bung 5 in a corresponding cross-sectional widening 13 in the plane of .: ...
2~)3Z53 the emptying spout 7. Depending on the position of the valve body 12, its angled throughflow opening 14 either aligns with the throughflow opening 15 of the emptying spout 7, or is turned so far relative to the emptying spout 7 in the CLOSED
position, that the valve body 12 blocks throughflow from the interior of the container to the emptying spout 7 projecting laterally outward.
Instead of a spherical valve body 12, however, the closure element 6 may also comprise an integral valve body 12a (as shown in Figure 3) which is designed to be pushed into the bung 5, tapering towards its center substantially in the shape of a centrally truncated double cone, and which comprises an angled throughflow opening 14 to the emptying spout 7 projecting laterally outward. The valve body 12a is sealingly mounted for rotation on the bung 5 in a corresponding double-cone-like cross-sectional reduction 13a in the plane of the emptying spout 7.
In addition, as shown in Figure 4, the closure element 6 may also comprise an integral cylindrical valve body 12b with a through flow opening 14 to the emptying spout 7. Closure element 6 is sealingly mounted for rotation on the bung 5 in a corresponding cylindrical cross-sectional reduction 13b, in the plane of the emptying spout 7, with annular sealing lips 16 overlapping the cross-sectional reduction 13b on both sides, and which comprises a lower frustoconical extension 16a for pushing the valve body into the cross-sectional reduction 13b of the bung 5.

20~)325~ ~
In all the illustrated embodiments, the valve body 12, 12a, 12b may be mounted for rotation between stops 17 defining an OPEN position and a CLOSED position on the outlet bung 5, as shown in the plan view of Figure 2. As shown in Figures 1 and 4, a stop pin 17 projecting axially either from the bung 5 or from the closure member 6 engages in a substantially arcuate recess 18 in the opposite part of the emptying device. The length of the recess 18 is gauged to correspond to the angle of rotation of the valve body 12, 12a, 12b between its OPEN and CLOSED positions.
In addition to the above-described embodiments, however, the emptying device may also be formed, as shown in Figures 5 to 7, with a pivotal lever 19, which projects radially outward from the closure member 6, and which between the thumb and index finger of one hand, can be pivoted to a degree limited by two stop pins 20, 21 between an OPEN position and a CLOSED
position of the valve body 12, 12a, 12b, as shown in Figure 7.
In order, in the above-described embodiments of the emptying device, to enable the valve body 12, 12a, 12b to be readily pushed into the bung 5 from outside after filling of the packaging container ?, the bung 5 can be made resilient, at least in the region of the increase 13 or reduction 13a, 13b in cross-section for the spherical or double-cone-like valve bodies 12, 12a, or cylindrical body 12b, respectively. As a result the closure element 6 can enter the opening of the bung 5 with the valve body from outside so that the wall of the bung 5 bears against the outer circumference of the valve body 12, or 12a, or 12b (or the sealing lips 16 of body 12b) which ZC~3253 resiliently and sealingly conform to the inner circumference of the bung 5.
Alternatively, the spherical 12 or double-cone-like valve body 12a may also be made resiliently in the form of a thin-walled blow molding, as shown in section in Figure 6, so thatit can be pushed into the opening of the bung 5 from outside so that the wall of the valve body 12 bears sealingly against the inner circumference of the bung 5 from inside. As shown in Figure 6, the closure element 6 may comprise a pull ring 11 preferably countersunk in a recess 10, by which the bung 5, when countersunk in the outer case 2a of a bag-in-box pack, can be gripped from the outside of the container after breaking of a perforation and withdrawn from the interior of the container 2.
Instead of the above-described embodiments comprising a valve body 12, 12a, 12b rotatable about the longitudinal axis of the bung 5, the emptying device may alternatively comprise a valve body 12c, which as shown in Figures 8 and 9, is in the form of a ball or roller body with a lateral opening 22.
Functioning as a three-way valve, valve body 12c is mounted on the bung 5 or on a corresponding adapter 5a to rotate about an axis extending transversely of its longitudinal axis 23 between stops defining an OPEN position and a CLOSED position. In the OPEN position, valve body 12c allows throughflow from the bung 5 to the emptying spout 7, and blocks that throughflow in the CLOSED position.

; `` '.
~ ~:003253 In the embodiment shown in Figures ~ and 9, the ball-like or roller-like valve body 12c comprises a pivotal lever 24, projecting radially outward transversely of its pivot axis.
The valve body 12c portion on the outside of the bung 5 or on the adapter 5a, is guided between stops in a longitudinal slot 26, which is closed by a tear-off strip 25 in shipping, and which is arranged in the diameter direction on a closure cap 27 covering the bung or the adapter 5a.
As in the embodiment shown in Figures 8 and 9, the valve body 12d in the embodiment shown in Figure 10 is also in the form of a ball-like or roller-like body, but comprises an emptying passage 14a, which extends substantially in the direction of the longitudinal axis 23 of the bung 5, and is bent at a straight angle, and an emptying spout 7 which is integral with the valve body 12d. Spout 7 is rotatably mounted with the valve body 12d in an opening 5b, the latter widening outward like a funnel. In operation, in a first end position of the emptying spout 7, the inlet opening 28 of the angled filling passage 14a is shut off from the interior of the container by the wall of the bung 5, and in a second end position, shown in dash-dot lines in Figure 10, allows throughflow between the interior of the container and the outer end of the emptying spout 7.
In this embodiment, thei emptying spout 7 carries a substantially hemispherical cover 29, covering the outer opening of the bung 5, with angled rim parts 30 for turning the valve body; 12d with one finger between the OPEN and CLOSED
positions relative to the bung 5.
