Definitions

• the invention relates to a spout for piercing into a container wall, with
• a puncture area which has a tip and at least one inlet opening
• a flange which is arranged between the penetration area and the pouring spout and can be placed on the container wall from the outside, and
• a device for clamping the flange and the container wall A device for clamping the flange and the container wall.
• the flange is formed in one piece with the piercing area and the pouring spout.
• the Eirfstech Symposium has a cylindrical portion adjacent to the flange, on which a sharp-edged external thread is formed. When the tip has been inserted into a container wall, the thread is screwed into the resulting hole by turning the spout until the flange has attached itself to the container wall from the outside. This is supposed to create a tight connection between the spout and the container wall.
• the pouring spout of the known pouring spout can be closed with a lid, there is also the danger that the container will inadvertently empty itself unintentionally if it is not stored vertically after the pouring spout is attached or is shaken during transport for the reasons mentioned .
• the invention is therefore based on the object of further developing a spout for piercing into a container wall in such a way that it can be securely sealed against the container wall with simple handling.
• the object is achieved on the basis of a pourer of the type described at the outset in that
• the insertion area has a shoulder facing away from the tip
• An elastic piece of hose is arranged between the shoulder and the flange, and
• the flange is axially adjustable towards the shoulder and can be fixed in a position in which the tube piece is axially compressed and thereby deformed radially outwards and is placed axially from the inside close to the container wall.
• An axially compressible and thus radially expanding tube piece is known for bottle closures which are inserted into a bottle neck and are tightly clamped in the bottle neck by radial expansion thereof.
• such known bottle closures must be removed before the contents of the bottle can be poured out, and the closure effect is based on the radial force which the axially compressed tube piece exerts on the inner wall of the bottle neck.
• the elastic tube piece extends from the shoulder of the insertion area to the flange, so that any thin container wall can be axially compressed between the tube and the flange by being axially compressed and thus can be clamped completely tight.
• the pourer according to the invention is suitable for thin-walled containers of any kind, for example in the form of bags made of film, pyramids or cuboids made of cardboard, as are used, for example, as packs for milk and fruit juices, or also for containers made of thin sheet metal, at most with the Restriction that the elastic compressible piece of hose must then consist of a particularly tough material, so that it cannot be prematurely destroyed by sharp-edged perforated edges of the sheet.
• an elastic piece of hose made of rubber of the type customary in the known bottle closures described is sufficient.
• the flange is adjustable by means of a lever which is pivotably mounted on the pouring spout and has at least one cam for generating an axial force.
• a lever which is pivotably mounted on the pouring spout and has at least one cam for generating an axial force.
• the flange is arranged at one end of a sleeve which is guided on a central part of the spout and is axially displaceable by pivoting the lever.
• the flange can be arranged at one end by means of a sleeve which is guided on a central part of the spout and can be axially displaced by rotating a nut part screwed onto the pouring spout.
• the flange can be formed in one piece on the sleeve.
• FIG. 1 shows a first exemplary embodiment of a pourer according to the invention before use, partly drawn in an axial section
• FIG. 2 shows the pourer according to FIG. 1 in the use position
• 3 shows a second example of a spout according to the invention before use
• FIG. 4 shows the spout according to FIG. 3 in the position of use.
• Each of the pourers 10 shown has a lance-like base body 12, which is made, for example, of stainless steel, but can also consist of hard plastic.
• the base body 12 has an insertion area 14 with a tip 16, a plurality of inlet openings 18 and a shoulder 20 facing away from the tip 16.
• the tip 16 is a slender cone in the two exemplary embodiments shown; however, it can also be bulbous - with convex cladding lines - to reduce the risk of injuries caused by careless handling and the risk of damage to the tip, especially if it is made of plastic.
• the shoulder 20 is adjoined in the direction away from the tip 16, ie upwards in the drawings, by a cylindrical middle part 22 and finally by a pouring spout 24 which is likewise cylindrical in the examples shown.
• the entire base body 12 is hollow from the pouring spout 24 to the inlet openings 18.
• An elastic hose 26 made of rubber or rubber-like plastic is pushed onto the cylindrical middle part 22, which is cylindrical inside and outside in the idle state according to FIGS. 1 and 3 and has an outside diameter that is just as large or slightly smaller than the outside diameter the shoulder 20.
• the tube 26 extends from the shoulder 20 up to a krei ⁇ ringförmigen flange 28 of the cylindrical middle part 22 is axially displaceable with very little radial play on "and, at least on its side facing the hose facing lower end face is planar.
• a sleeve 30 which is axially displaceable together with the flange 28.
• the sleeve 30 abuts the flange 28 from above and has its own flange 32 at its upper end, on which a washer 34 lies.
• a lever 38 is mounted on the pouring spout 24 by means of a transverse pin 36, which lever is stamped from sheet metal in the usual manner for bottle closures and has a pair of cheeks 40.
• the cheeks 40 each extend on one side of the pouring spout 24 parallel to the longitudinal axis A of the pourer 10 and are designed to be completely symmetrical to one another. They each have a cam 42 which is delimited by two flat flanks 44 and 46.
• the flank 44 of each cheek 40 is arranged at a smaller distance from the cross pin 36 than the flank 46.
• a container 50 which contains a liquid or free-flowing fine-grained material, is to be completely or partially emptied, the tip 16 and then the entire injection area 14 are pierced through a container wall 52, the flange 28 of which bears against the outside. 1 and 2 are then pivoted clockwise by an angle of approximately 110 ° to 120 ° in the example shown, the cams 42 sliding over the washer 34 and finally the flanks 46 rest on the washer 34 at a right angle to the longitudinal axis A.
• the spout shown in FIGS. 1 and 2 can be modified in that the sleeve 30 is omitted and the washer 34 rests directly on the flange 28, which is then designed to be more powerful. Instead or in addition, the washer 34 can also be omitted if the flange 28 or 32, on which the cams 42 then act directly, consists of correspondingly wear-resistant plastic with a low coefficient of friction.
• a particularly advantageous modification of the spout shown in FIGS. 1 and 2 is that the flange 28 is produced in one piece with the sleeve 30, expediently also made of plastic.
• an external thread 54 is formed on the pouring spout 24, onto which is provided a corresponding internal thread
• the sleeve 30 and the nut part 56 are preferably provided on their lateral surfaces with corrugations which make it easier for the user to apply torques.
• 3 and 4 differs from the one shown in FIGS. 1 and 2 only in that the axial displacement of the flange 28 required for sealing is effected by turning the nut part 56.
