TECHNICAL PROBLEM ~ 3The technical problem to be solved by the present invention is how to make a quick-release coupling for a foldable container that will allow a quick connection to the container emptying pump while automatically opening the valves in the container eagle, which is abnormally closed.

A further technical problem to be solved by the invention is how to achieve such an interface that can be transported from the manufacturer to the bag filling location as a single assembly, without additional assembly operations at the bag filling facility, and will also be taught to apply this, a unique assembly valve / immersed tube - container The folding bag inside the container does not damage during the filling or emptying process, nor does it contaminate the contents of the container.

It is also necessary to solve the construction of this interconnector so that it is inexpensive and can be obtained by a simple technological process of plastic molding.

BACKGROUND OF THE INVENTION

The present invention relates to a quick-release assembly for emptying and filling folding containers comprising a valve mounted in a housing.

The state of the art prior art does not find many examples of quick-release containers for filling and emptying containers, but they are most commonly designed as intermediate assemblies for adjusting the openings on the filling tubes and / or emptying with the opening on the container itself. The disadvantage of these solutions is that during filling the containers are overfilled, that is, the excess liquid is leaked and thus the containers are dirty. Also when separating the filling tube ie. disassembly of the coupling due to the lagging of small amounts of liquid in the coupling or in the pipe itself results in spillage at the filling point which is so often soiled by the container itself! They can get out into the container and cause contamination of the contents.

These, as well as other known problems of the known solutions, have been eliminated by the solution according to the invention, which will be described in detail with all its advantages hereinafter.

DESCRIPTION OF THE INVENTION

The quick-release assembly for emptying and filling folding containers of the invention relates to an immersion tube assembly comprising at least one or more ducts around its circumference, which substantially extends along the entire length of the immersed tube, as well as a valve with a quick-release coupling zone for application in combination with a collapsible, sealed container for emptying a liquid product therefrom, which is, in the case of the embodiment, a collapsible bag at the upper end of which a vacuum is created or sucked out, which is the subject of Yugoslav patent YU 42350.

Initially, the air is drawn from the inside of the folding bag. The liquid product in the collapsible bag will flow through the duct in the immersed tube and the collapsible bag will fold around the outer circumference of the immersed tube. Furthermore, as the liquid product is emptied from the collapsible bag, the bag will continue to fold about the outer circumference of the immersed tube until the liquid product is completely emptied of it.

Furthermore, the applicability of the present invention will be more clear from the detailed description below. However, it should be understood that the detailed onis of the invention and the specific examples, although showing desirable embodiments of the invention, are given by way of illustration only, since the various changes and modifications in the spirit of the invention will be apparent to those skilled in the art of the present invention.

The present invention will be more fully understood from the further detailed description with the accompanying drawings, which are given here by way of illustration only, and thus do not limit the present invention and where:

The present invention relates to a quick-release sludge having a submerged tube and a valve used in a collapsible bag for sinting fluid from the product. The collapsible bag has a nozzle connection or outlet, in which a valve with a quick-release coupling is installed, wherein the immersed tube can be mounted either in the bag connector or in the valve. The quick-adjustable valve coupler has been adapted to accept the reconditioning hose connection for emptying or filling the container. When the connecting elements are engaged, the valve is moved to the open position. The valve is normally pushed into the closed position when these switches are not stopped.

The present invention also relates to an immersion tube for use in combination with a collapsible, sealed container for emptying liquid products therefrom. The immersed tube according to YU 42350 can be used in combination with a post-mix beverage system. This system of subsequent beverage blending, which is incorporated herein by reference, belongs to the same applicant as the present invention, and is described in U.S. Patent No. 4,404,461 A of March 29, 1977.

As shown in Figure 1, the immersed tube 10 may have a trimmed end 12 for connection to the armature 14 of the bag. However, the immersed tube 10, according to the present invention, can be connected to a collapsible, sealed container 16, by means of a series of different connecting parts. For example, as shown in Figure 6 in the patent specification YU 42350, the seal 19 may be mounted on an immersed pipe 10 for connection to the bag armature 14. The seal 19 has an inverted edge 19A inward, which omits the sliding movement of the seal 19 per immersion, and tubes H 'in only one direction. 7bo ton, as the seal 19 is properly placed on the immersed tube Ib and the immersed tube 10 is drawn into a collapsible, sealed container 16 to touch the ar _: ..... - 4 bag sleeve 14, immersed tube n / will be arranged in a removable, sealed container 16.

The armature of the bag 14 in one embodiment comprises an almost horizontal wall portion 13 to which the edged end 12 of the tray 19 is secured securely so as to prevent lateral movement of the immersed tube 10 within the folding, sealing container 16.

The armature of the bag 14 comprises an upwardly extending circular wall 15 adapted to engage the valve coupling 17. As shown in FIG. 1, the oor ejected circular wall 15 may have projections 15A, which are engulfed by the corresponding projections 17A of the valve coupling 17. for locking two elements interconnected one relative to drunon.

In one embodiment of the present invention, the immersed tube 10 may be arranged within a folding, sealed container 16 arranged within a box 18. Such construction is commonly referred to as a bag-in-box.

When vacuum or suction is applied to the immersed tube 10 through a valve assembly, all air is initially discharged from the folding, sealed container 16. Then, the liquid product contained in the sealed container 16 will begin to drain out through the immersed container. tube 10 to empty and reach the discharge eagle not shown in the drawing. As the liquid product is emptied from the folding container, closed in container 16, the container is to be folded through an immersion tube 10 of vacuum created by suction using a pump. Normally, folding a foldable, sealed container in this way usually clogs the opening of an immersed tube, known in the art, and prevents further emptying of the product contained within a folded, sealed container. The immersed tube 10 of the invention described in YU 42350 discloses the disadvantages of known solutions by providing at least one channel in its circumferential surface extending substantially along the entire length of the immersed tube. Therefore, as the liquid product empties from the collapsible, sealed container 16, the container is assembled around a portion of the immersed tube 10, which is no longer surrounded by the liquid product, leaving the remainder of the channel open so as to allow complete emptying of the entire liquid product contained within the collapsible, sealed container. 16.

Figures 2 to 8 show the differences in the design of the bag 50 connectors according to the invention, valve assemblies in the bag 50, as well as alternative means for holding the immersed tube 10 either inside the bag 50 or within the bag armature.

-7 Bearing in mind the details in the figure, we can see here that here and hereafter it will be called the 50 bag coupling, which in effect performs the same ~ function as the bag 17 coupling in Figure 1. Namely, the 50 bag coupling comprises a valve assembly and provides a quick- the disassembling joint between the armature of the bag 54 and the hose fitting of the discharge gut, which will be discussed later.

As shown in Figure 2, the pouch coupling 50 is open at both ends to allow fluid flow through it, and contains a threaded vine 50A around the periphery of the outer wall near the upper end of the coupling, which engages the nut part of the hose coupling, support 50B for the lower edge of the intestinal junction, the lower extended portion of the SOC which runs into the socket 54A of the bag armature 54, and the circular sealing ring or rings 50D, which are dimensioned so that an enlarged spike is required in the socket 54A.

The bag armature 54 has a ring flange 54B which is thermally coupled or otherwise attached to a collapsible bag, generally designated 16. Inside the lower portion of the socket 54A of the bag armature 54 is a pen 56. The hub 56 is preferably cast as an intralateral portion of the bag armature 54.

Inside the lower portions of the socket 54A, the hub 56 has a centrally positioned, circular ring 56A defining the opening through which the immersed tube 10 is drawn into the container, as well as several radial ribs 56B. The central orifice opening 56 defined by the circular ring 56A is wide enough for the immersed tube 10 to be easily retracted, but the width of the support liner 52 of the immersed tube 10 (or the trimmed end of the immersed tube) does not allow the immersed tube 10 to fall through the opening into the bag. The central hub opening 56 is dimensioned such that the immersed tube 10 can easily be screwed in if desired. It can be observed from Figure 2 that once the bag-50 coupling containing the valve is inserted into the socket 54A of the bag reinforcement, the immersed tube 10 and the support liner 52 are sandwiched or sandwiched between the bag coupling and the pen 56. The space between the radial ribs 56B allows the container or collapsible bag to be filled with liquid before the immersed tube is drawn in without damaging or restricting fluid flow. The hub is positioned at the bottom of the annular socket 54A of the sack 54 fitting so that there is sufficient space for the coupling of the filling machine to seal against the socket 54A without touching the hub. In this way, the pen 56 can be maintained under sterile sterile conditions. The application of the ball 56 eliminates the need for an additional part or element for maintaining the immersed tube 10 in the bag armature 54.

Figure 3 shows a different shape of the bag 50 coupling in a retracted, sealed state within the armature 54 of the collapsible bag 16. In this embodiment, the bag 50 coupling has essentially the same diameter from top to bottom.

4 and 5 are cross-sectional views showing the internal construction of the bag assembly 50 of FIG. 3 in the closed and open positions respectively with the valve assembly. Coupling 50 of the bag, which in the proposed embodiment is molded from plastic, is also the body of the valve assembly.

The spring-loaded valve 60 is mounted inside the valve body, and is normally positioned in the closed position, the conical-recessed portion 62 of the valve being sealed in the opening 63 due to the action of the inclined spring 66 with which it is integrally cast, ending with a ring-shaped base 70. The base 70 of the bevelled spring 66 is secured to a groove in the inner wall of the coupling 50 of the bag.

The valve assembly further comprises an inner valve stem 64 which is intrinsically poured with a conical-recessed portion 62, an oblique spring 66 and a annular shaped base 70. The outer support 68 is internally poured inside the coupling 50 and centrally positioned therein by radial ribs 68A ( figure 4) to provide fluid passages around its perimeter.

As shown in Figure 4, the spring-loaded valve 60 is normally located in the opening 63 to prevent fluid flow through the valve body of the coupling 50 of the bag. On the other hand, Figure 5 shows a spring-loaded valve 60 in its moving conditions in response to the insertion of an interface connector 72 at the top of the connector 50 of the bag. Interface coupler 72 may be a conventional quick-release coupler, as shown in the Post-mix beverage industry for connecting well-known containers with FIGAL syrup to the emptying machine. The top of the interface connector 72 includes a serrated connector 76 to the hose, and the lower part has a downward portion providing a flap 74 that secures over the side walls of the connector 50 of the bag. The interconnector 72 may be threaded to the bag 50 via the threaded box 50A. As shown in Figure 5, when facing.:: - ~ 3Connector 72 threaded into the ria'Sv'6 is slotted in place and disengages the tapered recess 66 from the sealing engagement with the hole 63. The outer support 68 is pressed efforts at the interface coupling 72 to the valve member 72Λ to open it.

Thus, all valves are opened in suitable fittings and the fluid can flow freely from the bottom of the 50-bag coupling, through the interior and the interconnector 72, and through the toothed hose connection 76 to the emptying apparatus.

The pair constituting the inner valve stem 64 and the outer support 68 provides a unique advantage because the inner valve stem 64 with a spring-loaded valve 60 pushes the valve into the bag joint while pushing through the interface coupling, while the outer support 68 serves to open the valve element 72Λ within the interface connection . According to the thorn, the tapered spring 66 of the spring-loaded valve 60 does not have to be so strong that it opens the valve element 72A of the interface coupling 72, since the outer support 68, which is fixedly mounted inside the housing of the coupling 50, makes this opening. Since the fixed outer support 68 is able to work with very strong interface couplings, such as are desirable in the interface couplings 72, it is possible to use different constructions of the interface couplings 72 with the coupling 50 of the bag according to the invention. This provides additional advantages as the strong springs in the interface coupler obscure the very strong seal at high vacuum generated in the discharge system. If the outer support 68 is not provided then the bevelled spring 66 should be strong enough to open the interface coupling, or the spring assembly, after opening, should act from the bottom under constant voltage so that the valve support can then open the valve in the interface coupling. This would of course be undesirable because of the need for additional parts, which would further increase the complexity of the bag coupling assembly.

In the present embodiment, the entire coupling sleeve 50, and the spring-loaded valve 60, are molded from relatively inexpensive plastic material and can therefore be discarded if desired.

As shown in the embodiments of Figures 4 and 5, the bevelled spring 66 with a spring-loaded valve 60 has a pair of helical arms ending in a ring-shaped base 70. Hence, the bevelled spring 66 is similar in shape to a helical spring, allowing free and unimpeded flow through her. A different embodiment of the spring is further shown in Figure 6. According to Figure 6, the spring 80B is only an extension of the tapered-engraved Taptfvnon element fin, and has a plurality of bends, which are essentially cylindrical bellows. The inner stem of valve 80A is also provided and operates in a similar manner to the inner stem of valve 64 of embodiment 4 and 6. The base of the cylindrical spring 80B spring of Figure 11 is terminated by a ring circumference ROC that is secured within the walls of the coupling 50 of the groove. near its lower part. The annular rim of the SOC comprises a series of openings 82 for fluid passage arranged in its circumference allowing for free flow of fluid.

The valve assembly of FIG. 6 operates essentially in the same manner as the valve assembly of embodiments of FIGS. 4 and 5.

Referring to Figure 7, we can see that the bag 50 coupling with the spring-loaded valve assembly assembly shown in Figures 4 and 5 is shown here. The coupling 50 bag of Fig. 7 has a slightly different external shape to facilitate the use of various forms of interface couplings, namely, a quick coupling with a clamping spring that winds to the top of the coupling 50 of the bag, instead of joining by screwing it to the coupling. The top of the coupling 50 of the bag 7 has a tapered diameter extending downward to the extended support portion 92, and downwardly extending ribs 94. Thus, when the interface coupling is attached to the tapered end of the coupling 50 of the bag, it is sealed with its top with a circular ring seal 90 of shape 0, and connects to the outside by providing the ribs 94 with a fully turned position. The coupling sleeve 50 of the embodiment of FIG. 4 in YU 42350 is further provided with an extended flange 96 that allows the coupling to be held by the operator arm when inserted into the bag armor or attached to the front coupling.

Figure 8 shows a spring-loaded valve sleeve connection 50 of the type shown in FIGS. 4 and 5, with an immersed tube 10 engulfed at the bottom of the sleeve 50 or valve body by the support of an immersion tube 98. The submersible tube support 98 is a one-way sliding slide, as described in our Yugoslav patent application P 1774/80, and now Yugoslav patent no. 42350. However, in the embodiment of FIG. 8, the submersible tube strut retains the submerged tube 10 at the bottom of the valve body, (50 socket joints) instead of in the socket armature. For example, the valve / immersion tube assembly of Figure 8 may be drawn into the bag armature, and the collapsible bag 16, without engaging the immersed tube 10 and the coupling parts 50 of the bag, which come into contact with the product via the flange 96. Additionally, the valve / immersion assembly tube with Fig .:: - - ke 8 can be used with standard bags ";" grlarmature without the need for supporting fins, such as 56 from Figure 2. Therefore, filling the bag through an eagle or armature damages it the least. A further advantage is that the valve / immersion tube assembly of Figure 8 can be transported from the manufacturer to the bag filling location as a single assembly, without the need for additional assembly operations in the bag filling pooon.

It is clear that the invention described in this manner can be varied in many ways. Such modifications should not be construed as departing from the spirit and scope of the invention, and any such modifications will be understood by those skilled in the art, and should therefore be considered to be included in the appended claims.
