Definitions
- This invention relates to a safety keg closure.
- Liquids, especially beverages, are currently transported and stored under pressure in kegs.
- the container is installed at the distribution point and connected to the distribution device. When the beverage is distributed, it is expelled from the container under pressure.
- the container has an outlet to which - without loss of pressure - the distribution device is to be connected; the outlet mentioned must therefore be protected during transport and storage of the pressure vessel.
- this protection should include, in addition to protection against damage to the outlet, both the opening guarantee and the possibility of putting the protective closure back on.
- the safety keg closure according to the invention achieves this object.
- Closures of a similar type are also known from the patent literature:
- the snap lock according to GB-A 2097 768 has a tear-off flap which has to be torn open the first time it is opened. Tear-off flaps are themselves always a source of uncertainty and the closure opened in this way cannot be used again (line 100).
- the security lock according to US-A 4828 128 also has a tear-off tab. After tearing it off, the closure can be used again, but this requires several continuous inner wedge rings. In addition, the entire lowermost ring is removed and thrown away at the first opening together with the tear-off tab.
- US-A 4934546 is also a safety snap fastener, again with a tear-off flap, which is removed and discarded when it is first opened together with the lowest jacket ring of the fastener. The remaining closure can be used again.
- a solution without separating the closure parts is also obviously more ecological, especially since the remelting of today Molded parts made of polyolefins is a technically solved problem.
- the safety keg closure 1 according to the invention for wedge parts 1.3 on liquid pressure containers with closure lid 1.1 and closure jacket 1.2 is characterized by wedge parts 1.3 attached to the inner wall of the closure shell, which are arranged at a distance from the closure lid and which snap into the upper edge of the container , are not arranged on the entire circumference of the jacket and are partially connected to the closure via zones with reduced tear resistance 1.4.
- Eight symmetrically arranged wedge parts can be provided, four of which are alternately connected to the closure via zones with reduced tensile strength. However, four symmetrically arranged wedge parts are preferably provided, two of which are alternately connected to the closure via zones with reduced tensile strength.
- the zones with reduced tensile strength are usually designed in the form of webs / cavities between the wedge parts and the closure body, each web being reinforced, so that the wedge part does not completely detach from the closure when the zones mentioned are torn open.
- the wedge portions normally correspond to central angle openings of approx. 20 or approx. 40.
- the new safety keg closures consist of pressure-sprayable elastomers, especially polyolefins, preferably polyethylene or polypropylene.
- the safety kegs mentioned are manufactured using a multi-part, quick-opening injection mold.
- Fig. La sectional view of the safety keg closure according to the invention according to claim 3 (section through axis);
- Fig. 2 sectional view (schematic) d'es outlet neck of a liquid pressure vessel.
- FIG. 1 a shows a schematic representation in section through the axis of the safety keg closure 1 according to the invention with four wedge sections; the proportions do not correspond to the actual ones.
- the closing jacket 1.2 connects to the closing cover 1.1.
- the wedge parts 1.3 are attached to the inside of the sealing jacket, offset from the sealing cover. The wedges are designed so that they snap under the final thickening of the neck around the container outlet.
- FIG. 2 shows a schematic section through the longitudinal axis of the outlet neck 2 on the liquid pressure container.
- 2.1 denotes the actual neck of the container and 2.2 denotes a neck wedge reinforced all around.
- the end mentioned does not need to be specially wedge-shaped, it can also be semicircular or the like. his. In any case, such closures are designed such that the closure by means of wedge parts or the like. can be anchored underneath.
- the safety keg closure according to the invention after the first opening, i.e. after tearing open some or all of the wedge parts, it can be applied again to the outlet neck of the liquid pressure vessel, where it continues to act as a covering and protection against mechanical influences on the pressure connection part.
- the keg closure according to the invention described above can of course be modified within the scope of technical optimization without falling outside the scope of the patent.
- the wedge part can be realized in the form of individual small wedges (material saving).
