Definitions

  • the invention relates to a device for piercing liquid-filled containers, in particular tin cans filled with beer, with a holder for fixing the device relative to the container, with a piercing tube which penetrates the wall of the container and is sharp at the front, with a tap arranged on the tube and with a sealing sleeve surrounding the puncture tube and resting on the container wall.
  • the puncture tube is arranged displaceably in the holder. After the container to be pierced has been introduced into the holder, the puncture tube must be advanced relative to the stationary holder until it pierces the container wall. A special feed device is required for this.
  • the sealing sleeve is also not stationary with respect to the holder, but rather is displaceable relative to the latter against spring pressure.
  • the known device assembled from several individual parts, complicated to manufacture, prone to failure and not easy to use by laypersons.
  • the object is achieved in that the puncture tube is immovably connected to the holder and penetrates its wall when the same is placed on the container, and in that the sealing sleeve protrudes beyond the cutting edge of the puncturing tube, so that when the device is attached to the container, the sealing sleeve lies sealingly before the puncture tube penetrates the container wall.
  • a device for piercing liquid-filled containers in particular with pressurized liquids, for. B. beer-filled tin cans, as a holder a one-armed lever 1 of substantially U-shaped cross section (Fig. 4).
  • the length of the lever 1 corresponds essentially to the height of a tin can 2, the jacket 3 of which is to be pierced directly above the bottom 4 of the container.
  • the lever 1 has two claws 5, 6 (FIG. 4), which are cranked towards the container bottom 4 and serve as pivoting or rotating bearings for the lever 1. With these claws, the lever is suspended in a recessed flange 7 between the container jacket and the container base 4, the outer edge 8 forming a kind of pivot axis for the lever 1.
  • the lever 1 has at least one notch 9, which is at a distance from the claws 5, 6 such as is required to bridge the casing of the container 2.
  • the lever 1 is formed in the region of the notch 9 adjacent end slightly elastic so that the notch 9 with the edge 1 0 of the bead 11 is latched at the upper container bottom 12th
  • the latter is designed to be elastic in the region of its end adjacent to the locking notch 9. In the illustrated embodiment, this is done in that the lever 1 is relatively thin in this area and is designed as a handle 13 on which the lever can be comfortably gripped and pivoted.
  • the lever 1 comprises a main part 14 which extends essentially vertically on the container 2 to be opened, from which two parts 15, 16 project substantially perpendicularly towards the container 2, on which the claws 5, 6 and the locking notch 9 are arranged .
  • lever 1 With the lever 1 (FIG. 3) is rigid and connected to the container 2 projecting a puncture tube 17, the front or free edge of which is sharpened for the purpose of easy piercing of the container wall (jacket 3). Also rigid on lever 1 and surrounding puncture tube 17 is a sealing collar 18 made of rubber-elastic Provided material whose cross-sectional shape is shown in FIG. 3. As shown, a free edge 19 of the sealing collar 18 extends a little way beyond the front end of the puncturing tube 17, so that when the lever 1 is placed on the container 2, that is to say before the actual piercing process, the sealing collar 18 always seals on the outside of the container jacket 3 rests before the piercing tube 17 comes into contact with the jacket. This reliably prevents liquid from flowing or splashing out of the container when piercing.
  • a tap 21 connected to the puncturing tube, which consists of the following individual parts: an outlet pipe 22 which is in flow communication with the inside of the puncturing tube 17, a displaceable plug 24 loaded by a spring 23 with sealing washer 25, an axis 26 protruding from the plug 24 and a pivoting lever 28 which is pivotably supported on an edge 27 and engages on the axis 26.
  • the sealing disc 25 of the stopper 24 becomes lifted their seat so that liquid from the puncture tube 17 into the outlet 22 and from there into a glass or the like.
  • the described device works as follows: the lever 1 is hooked with the claws 5, 6 into the edge 8 of the lower flange 7, then pivoted into the position shown in FIG. 1 (clockwise) and with the notch 9 on the edge 1o of the upper flange 11 locked. First, the front edge of the sealing sleeve 18 seals against the outside of the container shell 3 and then the sharp edge of the puncture tube 17 pierces the container wall, so that liquid can enter the puncture tube 17 from the interior of the container. If the dispensing lever 28 is now actuated in the manner described, the liquid can escape via the outlet 22.
  • the main advantage of the described device lies in the simple, rigid arrangement of the piercing pin 17 and sealing sleeve 18 on the lever 1 serving as a holder and in that the front edge 19 of the sealing sleeve 18 projects beyond the cutting edge of the piercing tube 17, so that when the lever is applied 1 first a seal takes place on the container 2 and only then does the piercing mandrel penetrate the container wall.
  • the holder for the puncturing tube 17 and sealing sleeve 18 is not designed as a pivot lever, but in a different way.
  • the holder could also be designed as a clamping bracket that completely or partially encompasses the container 2, at whose clamping in the vicinity of the lower container bottom 4, the piercing mandrel 17, which is arranged rigidly on the bracket, penetrates the container wall, after a sealing with the sealing sleeve 18 has again been carried out beforehand.
  • Such a clamping bracket can advantageously also be designed as an elastic clamping band.
  • Other brackets have also proven to be useful, so that the invention is not limited to the design of the bracket as a lever.
  • the container is placed on a table or other base for the purpose of piercing so that the claws 5, 6 bearing point of the edge of the container and thus also the outlet 22 protrude beyond the edge of the table or base, so that a glass or. Like. Can be brought up to the outlet.
  • the tap 21 with outlet 22, the puncture tube 17 and the sealing sleeve 18 on an insert 29, which is in particular an injection molded part made of plastic, to manufacture this part separately and then into the claws 5
  • the outlet 22 snapping into a corresponding recess 31 in the lever 1 and thereby firmly connecting the lever 1 and the insert 29 to one another.
  • the puncture tube 17 has a flange-like extension 32, by means of which it is molded in the insert 29 is anchored.
  • the sealing collar 18 is inserted into a corresponding annular groove in the insert 29.
  • the plug 24 with the axis 26 is also slidably arranged in the insert 29, the contact surface for the sealing disk 25 also being formed in the insert.
  • FIG. 5 There are usually containers of the type shown in FIG. 1, which have different heights depending on the volume.
  • an adapter or spacer is provided, with the aid of which the effective distance between the claws 5, 6 and the notch 9 on the lever 1 can be reduced. This is shown in FIG. 5.
  • the spacer 33 is placed in a known manner on the part 16 of the lever 1 carrying the notch 9, pushed on or releasably fastened there in some other way.
  • the spacer 33 has a locking notch 34 which, in the operating position, lies as far below the locking notch 9 as the difference in the heights of different containers 2.
  • the lever 1 can also be used for piercing smaller containers than shown in FIG. 1.
  • a bung hole is provided on the upper container bottom 12, via which the container is filled. After filling, the bunghole is closed with a plug-like bunghole closure made of rubber or the like, which is provided with reference number 35 in FIG. 2 and has a membrane-like transverse wall on the inside, which is equipped with a corresponding device, for example a spear or the like can be easily pierced.
  • an inner core which can be pressed into the container can also be arranged in the bunghole closure 35.
  • a ventilation mandrel 36 is additionally attached to the mentioned spacer 33, which, if necessary, can be used to pierce the aforementioned membrane of the bunghole closure 35 or to press in the inner core.
  • the Aeration mandrel 36 can be connected to the spacer 33 in a fixed or detachable manner.
  • the ventilation mandrel 36 can also have a sharp tip, with the aid of which a direct puncture of the container wall, in particular the upper container base 12, is possible.
