Abstract:
The invention relates to an arrangement for pouring free-flowing media out of a container. The arrangement contains a pour-out valve ( 3, 50 ) which can be specifically opened and closed by the user via an easy to operate actuating device ( 9 ), and thus allows a controlled pouring-out action. A pour-out tube ( 2 ) arranged in a pivotable manner on the container ( 1 ) makes it possible, depending on the position of the pivoted pour-out tube ( 2 ), to lock or unlock the pour-out valve ( 3, 50 ) using a blocking device. Locking the pour-out valve in the closed position prevents accidental opening of the pour-out valve ( 3, 50 ). The arrangement according to the invention also contains a venting valve ( 8 ), which can likewise be locked in the closed state. A compression spring ensures that, in the rest state, that is to say when the actuating device ( 9 ) is not actuated, the pour-out valve ( 3, 50 ) seals off the spout and the venting valve ( 8 ) is likewise closed.

Description:
BACKGROUND OF THE INVENTION 
     The invention relates to an arrangement for pouring free-flowing media. 
     Conventional pouring-out arrangements on containers for storing and dispensing partial quantities of free-flowing media comprise a container body with a closable spout and a likewise closable filling opening. In the closed state, the container is closed in a sealing manner so that the medium located in the container cannot flow out regardless of the position of the container. This type of container is used, for example, as a refilling container for small tanks or as containers of concentrates or additives in which only a partial quantity is removed from the container during each use. For pouring out, a pour-out tube can be screwed or fitted onto the container and when required, the refill opening is screwed on so that air can flow into the container to allow continuous pouring-out. At the end of the pouring-out process, the pour-out tube is removed from the pour-out opening again and stored and the container is closed. The handling of containers having such a pouring-out arrangement is laborious and has the risk that the liquid can run out freely when the unclosed container is tilted. Frequently a movable bellows is used as a pour-out tube for better adaptation to the respective position of the tank or container to be filled. In this case, residual quantities of the filled medium remain in the grooves of the bellows. This has the disadvantage that the pour-out tube or the bellows and the container in the area of the spout is contaminated with the filling medium on every use, which inevitably has the result that the user comes in contact with the filling medium. In addition, the pour-out tube can easily be lost if it is detached from the container. 
     Known from the publication WO2004/020298 is a container in the form of a petrol can having a pour-out arrangement comprising a spout with a pour-out valve, an actuating device for a pour-out valve, a pour-out tube arranged on the container, a venting valve and a closable filling opening. The flexible pour-out tube screwed onto the spout is covered with a closure cap at its outer end as is the venting valve when not in use, thus ensuring that the container is tightly sealed when not in use. The pour-out valve is controlled by means of a connecting member with a push button which at the same time actuates the venting valve so that when the pour-out valve is opened, the venting valve is also opened. When not in use, both the pour-out valve and the venting valve are closed. In order to be able to remove petrol from the can, the closure caps are first unscrewed from the flexible pour-out tube and from the venting valve. Then by actuating the push button, petrol can be removed from the container in a metered manner. The disadvantage of this arrangement is that closure caps have to be screwed on for securing and for tightly sealing the container. In addition, during transportation of the container, for example, small quantities of petrol can seep through the pour-out valve into the pour-out tube or through the venting valve into the cover caps which can lead to contamination when unscrewing the cover caps from the pour-out tube or from the venting valve. 
     SUMMARY OF THE INVENTION 
     The object of the present invention is to eliminate these disadvantages of the known arrangements for pouring out free-flowing media from a container. 
     The basic idea of the invention is that with the arrangement according to the invention for pouring out free-flowing media without mounting loose and additional parts, a container can be transferred from the closed and securely sealed state to an operationally ready state and back again. For this purpose, the invention comprises a pour-out valve that can be specifically opened and closed by the user by means of an easy-to-operate actuating mechanism and thus allows controlled pouring-out. A pour-out tube arranged pivotally on the container makes it possible to lock or unlock the pour-out valve according to the position of the pivoted pour-out tube by means of a blocking device. Locking the pour-out valve in the closed position avoids any unintentional opening of the pour-out valve. The arrangement according to the invention further comprises a venting valve which can likewise be locked in the closed state. A compression spring ensures that in the rest state, that is when the pour-out control is not actuated, the pour-out valve sealingly closes the spout and the venting valve is likewise closed. 
     The arrangement according to the invention is used for pouring out various free-flowing media from a container. In this case, the arrangement can be integrated in the container itself or in a lid of the container. The free-flowing medium can, for example, be cleaning agents, lubricants, petrol, screen wash agents, antifreeze agents, additives in the construction area and many others. Free-flowing media are to be understood as fine-grained powders, granules and the like which are stored airtight in containers and are removed from the container in small partial quantities. The container fitted with the pour-out arrangement forms a storage and transport container from which a partial amount of its content can be removed from time to time. For the removal of a partial quantity of the content from the container, the pour-out tube is initially pivoted away from the container into the pour-out position. At the same time, the pour-out valve is unlocked. The venting valve is then unlocked and by actuating the pour-out control, both the pour-out valve and the venting valve are opened and the content can be poured out. In this case, the pouring out is effected in a controlled manner without any of the contents spilling and without the user coming in contact with the content of the container. A tube with a smooth inner wall is used as the pour-out tube, so that no residual quantities remain in the pour-out tube after the pour-out process. At the end of removal, the pour-out control is released, whereby the compression spring closes both the pour-out valve and the venting valve, the pour-out tube is pivoted into the blocked position and the venting valve is locked. The container is therefore sealed again and reliably closed. The locking of the pour-out valve and the venting valve make it impossible for the free-flowing medium to flow unintentionally out of the container. 
     Further advantages of the invention follow from the dependent claims and from the following description in which the invention will be explained in detail with reference to two exemplary embodiments shown in the drawings.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     In the figures the same reference numerals have always been used for the same elements and explanations for the first time relate to all figures unless expressly stated otherwise. 
       FIG. 1  shows a portable container  1  with an exemplary embodiment of the pour-out arrangement according to the invention. The essential components of this arrangement are a pour-out tube  2  arranged pivotally on the spout  13  of the container  1  comprising a pour-out valve arranged in the interior of the pour-out tube  2  and a lock for the pour-out valve, an actuating device  9  with a push-button for actuating the pour-out valve, a connecting member between the push button and the pour-out valve and a lockable venting valve integrated in the actuating device  9 . Also provided on the upper side of the container is a filling opening  5  which can be closed with a lid  6  and a handle  32 . The filling opening  5  is arranged on the container  1  in such a manner that it lies lower than the upper container boundary. This has the result that the container  1  cannot be overfilled. When, during filling of a container placed on the ground, the level of the filling opening is reached, a sufficiently large gas cushion remains inside the container  1 , capable of absorbing volume and pressure fluctuations accompanying temperature fluctuations. The actuating device  9  is arranged close to the container handle  32  so that the container can be held by the handle  32  in one hand and the push button  10  on the actuating device  9  can be operated with the same hand. The pour-out tube  2  is pivoted over the container  1  and is located in the blocking position. In this position, the pour-out valve is locked and the container  1  tightly closed. 
       FIG. 2  shows the components of the pour-out arrangement in detail, wherein the pour-out tube  2  is cut away in the area of the pour-out valve  3  located inside the pour-out tube  2 . A flexible push rod  7  can be identified as the connecting member between the actuating device  9  and the pour-out valve  3 , said push rod being guided in a channel  15  integrated in the container wall. The push rod  7  can also be guided in a channel- and/or tube-like structure which is formed as part of the container or they can be separately inserted parts. The push rod  7  can, for example, be a flexible, bendable length of metal or plastic whose length is matched to the curve path of the channel in which it is guided and extends from the actuating device  9  as far as the pour-out valve  3 . The connecting member  7  can be composed of a plurality of individual elements. 
       FIG. 3  shows the container  1  with pivoted pour-out tube  2  ready for pouring out, i.e. in this position the pour-out valve  3  is unlocked but still closed. By pressing the push button  10  the push rod  7  is pushed along the channel  15  towards the pour-out valve  3  which is thereby opened. In the embodiment shown, the pour-out tube  2  is arranged pivotally about an axis running parallel to the pour-out collar  14  of the spout  13 , being pivotable through about 180° from the blocking position into the pour-out position. For a container standing on the ground, this corresponds to an approximately horizontal pivoting process. However, it is also feasible to have a pivoting arrangement at the spout  13  which allows pivoting of the pour-out tube  2  running in the vertical direction, wherein the pour-out valve  3  is likewise locked in the blocking position and in the pour-out position of the pour-out tube  2 , the pour-out valve  3  is unlocked. A pour-out connecting piece  12  is rotatably arranged at the front end of the pour-out tube  2 . The pour-out connecting piece  12  has a slight bend or arcuate profile. As a result, the pour-out tube  2  with the pour-out connecting piece  12  can be introduced more simply and more easily into the opening of a vessel or container to be filled. A recess  16  can also be identified on the upper side of the container  1  which serves to accommodate the pour-out tube  2  in the blocking position. The outer flank of the recess  16  is slightly elevated and forms a rib  17  running parallel to the recess  16 . On pivoting the pour-out tube  2  into the blocking position, the pour-out tube  2  must be pressed with gentle pressure over this rib  17  so that it ultimately comes to rest in a gently engaging manner in the recess  16 . As a result, the pour-out tube  2  cannot be pivoted unintentionally from the blocking position. The pour-out tube must be pressed away over the rib  17  with slight pressure for pivoting. 
       FIG. 4  shows a partial view of the pour-out tube  2  in the area of the spout  13  with closed and locked pour-out valve  3 , shown perspectively in section. A collar  14  can be seen at the spout  13  of the container  1 . The collar  14  is integrated in the upper wall of the container and has a circular constriction  18  at its upper opening. The inwardly directed surface  19  of this constriction  18  runs in a conically bevelled manner such that the diameter of the opening tapers in the direction of the container. This conical surface  19  forms the valve seat  19  for the pour-out valve  3 . Instead of a conical surface  19 , it is also feasible to have a concave surface  19  such as the inner surface of a spherical layer for example. As a result, inaccuracies in the axial position of the pour-out valve  3  can be reliably absorbed, ensuring secure sealing of the pour-out valve  3 . The pour-out tube  2  has a pipe-like form. At its container-side end, the pour-out tube  2  opens in a cylindrical, upwardly closed and downwardly open cylindrical section  21 . This cylindrical section  21  is placed on the collar  14  of the spout  13  and is operatively connected thereto via a thread  21 . On pivoting the pour-out tube  2 , the cylindrical section of the pour-out tube  2  is raised or lowered by the thread  20  according to the pivoting direction and specifically in such a manner that in the blocking position of the pour-out tube  2  the cylindrical section  21  is lowered the furthest and in the pour-out position, it is raised the furthest. A radially circumferential groove  22  is let into the upper edge zone of the collar  14 , which serves to receive a first sealing element  23 . This first sealing element  23  forms a sealed transition between the container  1  and the pour-out tube  2 . The pour-out valve  3  is inserted in the circular constriction  18  of the spout  13 . The valve cap of the pour-out valve  3  has a shape similar to a ring cake and in the upper outer edge zone, has a radially circumferential groove  24  for receiving a sealing element  25 . In the closed state the sealing element  25  rests on the valve seat  19  and sealingly closes the opening of the spout  13 . However, it is also feasible that the valve cap itself forms the sealing element  25 , i.e. in that it is made entirely or in the area of the valve seat from a sealable material and thereby makes it possible to achieve a reliable and sealing closure of the spout  13  with the valve seat  19 . Vertically running protuberances or ribs  38  are arranged on the outer wall of the valve cap, which centre the valve cap during closure of the valve  3  in the valve seat. The upper side of the cylindrical section  21  of the pour-out tube  2  has a plate-shaped recess  26 . In the blocking position of the tube  2 , the side wall  29  of the plate-shaped recess  29  presses against the upper edge of the pour-out valve  3  and thereby presses the valve seal  25  against the valve seat  19 . The cooperation of the upper edge of the pour-out valve  3  with the plate-shaped recess  26  of the pour-out tube  2  forms a blocking device for the pour-out valve  3 , which can thereby not be raised from the valve seat  1 . 9  in the blocking position. 
       FIG. 5  shows a partial view of the container  1  in the area of the spout  13  with closed and unlocked pour-out valve, shown perspectively in section. The pour-out tube  2  is pivoted into the pour-out position, whereby the cylindrical section  21  is raised to its highest position. The plate-shaped recess  26 ,  28 ,  29  of the pour-out tube  2  no longer lies on the valve pin  27  and on the upper edge of the pour-out valve  3 . As a result, the pour-out valve is displaceable in the axial direction. A helical compression spring  11  is arranged around the valve pin  27  between the centre of the plate-shaped recess  28  of the pour-out tube  2  and the pour-out valve  3 , which spring presses the pour-out valve  3  from the underside of the plate-shaped recess  28  into the valve seat  19 . The pour-out valve is thereby unlocked but is closed due to the compression spring  11 . At the centre the valve pin  27  has hole running axially in the direction of the container which serves to receive the push rod  7 . 
       FIG. 6  shows a partial view of the pour-out tube  2  in the area of the spout  13  with open and unlocked pour-out valve  3 , shown perspectively in section. The push rod  7  pushes the pour-out valve  3  against the spring force  11  from the valve seat  19  so that the spout  13  is released and the free-flowing medium can flow out through the pour-out tube  2  when the container is suitably inclined. 
       FIG. 7  shows the actuating device  9  with the push button  10  for actuating the pour-out valve  3  with open venting valve  8 , shown perspectively in section. On the outer upper side of the container, a cylindrical projection running approximately parallel to the upper side of the container having the opening  34  is integrated in the wall of the container  1 . The actuating device  9  is placed or sealingly screwed onto this projection having the opening  34 . The actuating device  9  consists of a valve holder  30 , a venting piston  31  and a push button  10 . The valve holder  30  has a constriction  35  with an inwardly directed sealing surface  36 . At its container-side end the venting piston  31  has a diameter which approximately corresponds to that of the cylindrical opening  34 . Towards the outside the diameter of the venting piston  31  tapers towards the diameter of the constriction  35  in the holder  30 . The venting piston  31  is thereby guided in the inner wall of the opening  34  and in the constriction of the holder  30  and is displaceable in the axial direction. In the transition zone from larger to smaller diameter of the venting pistons  31 , there is provided a radially running groove with a valve seal  33  for the venting valve  8 . This venting valve  8  is obtained from the cooperation of the venting piston  31  with the seal  33  and the constriction of the holder  30  with its sealing surface  36 , which forms the valve seat for the venting valve  8 . A hole on the container-side end serves to receive the push rod  7 . 
       FIG. 8  shows the actuating device  9  with the push button  10  for actuating the pour-out valve  3  with closed venting valve  8 , shown in perspective view. The push rod  7  is pressed by the compression spring  11  in the pour-out valve  3  in the direction of the actuating device  9 . As a result, the venting piston  31  with its seal  33  is pressed towards the back against the sealing surface  36  in the constriction  35  of the holder  30 , the valve seat and the container  1  is sealed towards the outside. If, by pressing on the push button  10 , the venting piston  31  and the push rod  7  are pushed against the spring force of the compression spring  11  in the direction of the container, the venting valve  8  and the pour-out valve  3  are raised from the valve seats and pressure equalization with the ambient air pressure can be effected in the container  1  by the venting valve. The content can be emptied from the container through the opened spout. In order to prevent unintentional opening of the venting valve, a blocking device is provided on the actuating device. An axially disposed groove runs in the outer region of the holder which is designed to receive a cam disposed on the push button  10 . The push button  10  is rotatable about the longitudinal axis with the venting piston  31 . As soon as the venting valve  8  is closed, the cam is located outside the groove and the push button  10  can be turned. An axial displacement of the push button  10  or the venting valve  8  is only possible however, when the push button is positioned or turned such that the cam engages in the groove. That is, when the venting valve is closed, the push button is turned into a blocking position, thereby locking the venting valve. Only when the push button  10  is turned back into that position in which the cam engages in the groove, can the push button be pressed and the valve is actuated. The push button  10  and the venting piston  31  are guided in a link in the holder  30  of the venting piston  31 . On turning the push button  10  from the open position into the locking position, this is displaced with the venting piston  31  in the axial direction away from the container so that the seal  33  of the venting piston  31  against the valve seat  36  is pulled or pushed in the holder  30 . An engaging mechanism is also provided on the push button  10  which engages in the holder and on the one hand allows a specific and pre-defined positioning of the push button  10  and on the other hand secures the push button  10  against unintentional twisting from the blocking position. The container is hermetically sealed by the locking of the pour-out valve  3  and the venting valve  8  so that some of the filling medium cannot escape through the pour-out valve  3  nor through the venting valve out from the container nor can liquid penetrate into the container from outside. Even when the pour-out and/or venting valve is unlocked, with the arrangement for pouring out free-flowing media according to the invention, the container  1  is tightly closed so that none of the contents can flow out of the container even when it is tipped over. The container can only be emptied when the valves are unlocked and opened by pressing the button. 
     A further embodiment of a container  1  with integrated pouring out arrangement is shown in  FIG. 9 . The essential components of this arrangement are again a pour-out tube  2  disposed pivotally on the spout  13  of the container  1 , a pour-out valve disposed inside the spout  13  and a lock for the pour-out valve, an actuating device  9  with a pressure slider  10 ′ for actuating the pour-out valve, a connecting member between the push lever  10 ′ and the pour-out valve, i.e. a push rod and a venting valve lockable with the pressure slider  10 ′, which is integrated in the actuating device  9 . A filling opening  5  which can be closed with a lid  6  is further provided in the upper region on the container side. The container  1  has an upwardly tapering shape so that the filling opening  5  does not protrude beyond the base surface of the container  1  in the projection. This has the advantage that the containers can be stored adjacent to one another, bottom surface on bottom surface. A handle  32  is integrated in the container on the upper side and on the rear side wall. The cavities of the handles  32  are connected to the interior of the container  1  so that when the container  1  is filled and closed, a sufficiently large gas cushion remains which can absorb the volume or pressure fluctuations accompanying temperature fluctuations. The actuating device  9  is arranged close to the handle  32  on the rear side wall so that the container  1  can be held by the handle  32  with one hand and the pressure slider  10 ′ on the actuating device  9  can be operated with the same hand. The pour-out tube  2  is pivoted over the container  1  and is located in the blocking position. In this position, the pour-out valve is locked and the container  1  tightly closed. A marking  40  can be seen on the side wall of the container  1 . If the container wall is transparent, this marking  40  can reveal the amount of liquid in the container both in the vertical and in the horizontal holding position of the container  1 . 
       FIG. 10  shows the container  1  with the pour-out tube  2  pivoted ready for pouring out, that is in this position the pour-out valve is unlocked but still closed. The pressure slider  10 ′ is pivoted backwards, thereby unlocking the actuating device  9 . The locking of the actuating device  9  will be described in detail in the following. By pressing the pressure slider  10 ′, the push rod is pressed against the pour-out valve which is thereby opened, In the embodiment shown the pour-out tube  2  is pivotable by about 180° in a vertical plane from the blocking position into the pour-out position. In the unlocked position, the pour-out tube  2  points away from the container  1 . A lug  41  can further be identified on the upper side the side wall of the container  1 , said lug being formed by a protuberance in the container wall and serving to receive the pour-out tube  2  in the blocking position. 
       FIG. 11  shows a partial view of the spout  13  with closed and locked pour-out valve  50 , shown in a horizontal section. The container opening with the collar  14  and the spout  13  disposed thereon can be seen. The spout  13  consists of the valve  50  with the valve seat  52  and the valve disk  53  inserted in the collar  14 , as well as the housing  42  and the pour-out tube  2 . The spout  13  is screwed to the collar  14  of the container  1  by means of the retainer nut  44 . A cylindrical element  51  is inserted in the collar  14 , said element having a rim at one end which rests sealingly on the collar edge and having a conically running surface at its end facing the interior of the container  1 , which forms the valve seat  52  for the valve disk  53 . The valve disk  53  has a radially circumferential groove for receiving a sealing element  55 . In the closed state, the sealing element  55  rests on the valve seat  52  and sealingly closes the opening of the spout  13 . At the centre of the valve disk  53 , this has a forwardly directed valve sleeve  54 . The push rod sleeve  47  is mounted displaceably in the longitudinal direction in said valve sleeve  54 . A compression spring  46  is inserted between the push rod sleeve  47  and the valve sleeve  54 , which spring pushes the push rod sleeve  47  in the direction of the container interior away from the valve sleeve  54 . At its rear end, said push rod sleeve  47  has a sleeve-shaped opening for receiving the pushrod  57 . The edge of the housing  42  rests on the outer edge of the rim of the cylindrical element  51  which is held by the retainer nut  44 . The retainer nut  44  is screwed to the container collar  14  by means of the thread  48 . In the connecting region to the cylindrical element  51 , the housing  42  has a plurality of radially inwardly running webs  56  which serve to receive a compression spring  45 . This compression spring  45  extends over the valve sleeve  54  and rests with its second end on the valve disk  53 , and presses this against the valve seat  52 , whereby the container  1  is sealingly closed in the area of the spout  13 . 
     In the housing  42  the pour-out tube ( 2 ) is rotatably mounted about an imaginary axis A which runs perpendicular to the outflow direction  58  from the container  1 . The pour-out tube  2  has a 90° curvature in such a manner that when the spout  63  of the pour-out tube  2  pivots vertically, the pour-out tube  2  turns about the imaginary axis A. A seal  49  is provided on the housing  42  for sealing the pour-out tube  2 . A web  59  disposed on the circumference of the pour-out tube  2  engages in a recess  60  in the housing  42  and guides the pour-out tube  2  during pivoting. In the end region of the pour-out tube  2  in the housing  42 , the tube has an opening  61  in the tube jacket  62  which is disposed such that it is oppositely directed to the outflow opening  63  of the pour-out tube  2 . That is to say, the opening  61  in the tube jacket  62  is facing the container collar  14  when the outflow opening of the pour-out tube  2  is pivoted away from the container. As soon as the outflow opening  63  of the pour-out tube  2  points towards the container  1 , the opening  61  in the tube jacket  62  faces away from the container collar  14 . In this case, the valve sleeve  54  abuts against the tube jacket  62  and this presses the valve sleeve  54  with the valve disk  53  against the valve seat  52 . In this position, the pour-out valve  50  is locked and cannot be opened with the pushrod  57 . 
       FIG. 12  shows the same area of the container  1  as in  FIG. 11  but in a vertical section. The tube jacket  62  appears half-moon-shaped. The valve sleeve  54  is blocked by the tube jacket  62  in such a manner that the valve  50  cannot be opened. To actuate the pour-out valve  50 , the push rod sleeve  47  must be pushed with the push rod  57  against the spring force of the first compression spring  46  in the valve sleeve  54  in the direction of the pour-out tube  2 . Depending on the ratio of the spring force of the first compression spring  45  to the second compression spring  46 , in extreme cases the push rod  57  must possibly be pushed forward until the lower edge zone of the push rod sleeve  47  reaches the bottom of the valve sleeve  54  and only then during further pressing of the push rod  57  against the spring force of the compression spring  45 , is the valve disk  53  raised from the valve seat  52  and the container opening is opened. In this case, the first compression spring  46  in the push rod housing  47  on the one hand has the task of pressing the push rod  57  towards the back and holding the valve of the actuating device  9  closed, and on the other hands it has the task of compensating for length fluctuations of the push rod  57 . The container  1  and the push rod  57  expand differently according to filling, temperature and pressure so that the spacing between the valve disk sleeve  54  and the actuating device  9  varies. Therefore, in order to compensate for the different expansion of the container  1  and the push rod  57 , a compensating path  64  is provided in the valve sleeve  54 . This means that the push rod sleeve  47  projects to different depths in the valve sleeve  54  when the container is closed and locked, depending on temperature, pressure and filling of the container  1 . 
       FIG. 13  shows a partial view of the spout  13  with closed and unlocked pour-out valve  50 , in a vertical section. The spout is unlocked by pivoting the pour-out tube  2 . The tube jacket  62  exposes the valve sleeve  54  so this can be pushed forwards. The push rod  57  is pushed forwards until the push rod sleeve  47  has reached the bottom of the valve sleeve  54 . The valve disk  53  with its valve seal  55  is pushed further against the valve seat  52  by the compression spring  45 . The valve  50  is still closed. 
       FIG. 14  shows a partial view of the spout  13  showing the opened pour-out valve  50  in a horizontal section. The pour-out tube  2  is pivoted forwards away from the container  1 , thus unlocking the spout. By pressing against the spring force  45 , the valve sleeve  54  is pushed forwards into the opening  61  in the tube jacket  62  of the pour-out tube  2  and the valve disk  53  with the seal  55  is raised from the valve seat  52 . The spout of the container  1  is thereby opened and the medium located in the container can flow through the opened pour-out valve  50  into the pour-out tube  2 . 
       FIG. 15  shows a partial view of the container  1  showing the actuating device  9  for actuating the pour-out valve  50  with closed and locked venting valve  8 , shown in a vertical section. The actuating device  9  consists of the venting valve  8  and the pressure slider  10 ′. The upper handle end of the rear container handle  32  is configured as a guide rail  66 . The container wall of the container  1  has an opening in the area of the guide rail  66 , whose inner edge forms the valve seat  65 . In the inner area the valve disk  67  has a blind hole for receiving the push rod  57 . In the closed state the compression spring  46  presses the push rod  57  towards the back and the valve disk  67  with the seal  33  rests sealingly on the valve seat  65 . The valve disk  67  is guided displaceably along the rail  66  with its backwardly projecting U-shaped neck  68 . A vertically pivotable pressure slider  10 ′ is located at the outer end of the valve neck  68 . In  FIG. 15  the slider  10 ′ is pivoted forwards and presses against the wall of the container  1 . The valve disk  67  is thereby pressed against the valve seat  65  and blocks the venting valve  8  in the closed state. 
       FIG. 16  shows the actuating device  9  with rearwardly hinged pressure slider  10 ′ for actuating the pour-out valve  50  with the venting valve  8  closed. The push rod  57  is pressed by the compression spring  45  in the direction of the actuating device  9 . The valve disk  67  with its seal  33  is thereby pressed towards the back towards the valve seat  65  and the container  1  is sealed towards the outside. The outwardly directed surface of the pressure slider  10 ′ is configured so that it is easy to reach and operate with the thumb when the container  1  is held with one hand on the rear handle  32 . 
       FIG. 17  shows a partial view of the actuating device  9  with opened venting valve  8 , shown in a vertical section. By pressing on the pressure slider  10 ′ the valve disk  67  with the push rod  57  is pressed against the spring force of the compression spring  46  in the direction of the pour-out tube  2  and the venting valve  8  and the pour-out valve  50  are opened. Due to the opened venting valve  8  pressure equalization with the ambient air pressure can take place in the container  1  and the contents can be emptied from the container through the opened spout  13 . In order to prevent unintentional opening of the venting valve  8 , the pressure slider  10 ′ is folded forwards, thus closing the pour-out valve  50  and closing and locking the venting valve  8 . 
     The arrangement according to the invention for pouring out free-flowing media has been explained for two examples of a portable container in which the arrangement is integrated in the container or its walls. In a further embodiment the components of the arrangement are integrated in a container lid which can be screwed onto or placed onto a container by means of a sealing connection such as, for example a screw-lid connection or a bayonet plug-on connection. This has the advantage that a lid with the arrangement according to the invention can be used for containers of different sizes. In a further embodiment it is also feasible to integrate the arrangement for pouring out free-flowing media in a container intended to receive cartridges or cartouches.
