Definitions
- the invention relates to a pressure relief valve for a
- the pressure relief valve according to the invention for a packaging container with the features of claim 1 has the advantage that it opens at relatively low pressures in the package inside (for example, in the order of 5 mbar), that is, in the inside of the package resulting gases even at a relatively low pressure to the outside passes.
- FIG. 1 shows a longitudinal section through a first inventive pressure relief valve in the region of a packaging material wall of a packaging container
- FIG. 2 shows a plan view of the overpressure valve according to FIG. 1,
- FIG. 3 shows a detail of the overpressure valve according to FIG. 1 in the region of the edge region of the overpressure valve
- FIG. 4 shows a detail of the overpressure valve according to FIG. 1 in the region of a tower-like elevation
- FIG. 5 shows a plan view of a second inventive overpressure valve
- FIG. 6 is a sectional view in the plane VI-VI of FIG. 5;
- FIG. 7 is a plan view of a third pressure relief valve according to the invention;
- FIG. 8 is a section in the plane VIII-VIII of FIG.
- Figures 9 and 10 are plan views of further pressure relief valves according to the invention.
- a first pressure relief valve 10 is shown.
- the pressure relief valve 10 is mounted on the inside 2 of a packaging material wall 1, which forms by appropriate folding and sealing a packaging container or a packaging bag for packing gas-releasing food such as coffee.
- the pressure relief valve 10 has a round body 11 made of plastic by injection molding.
- the main body 11 has a peripheral edge region 12, on whose inner side 2 of the packaging material wall 1 facing end face, for example, a circumferential, triangular in cross-section elevation 13 is formed.
- Survey 13 can be the main body 11 on the inside - A -
- the base body 11 has a base region 15 which is lowered in relation to the edge region 12.
- the base region 15 is not flat or flat on the side facing the packaging material wall 2, but arched. In this case, preferably a concave curvature is used, such that the central
- Area 16 of the base region 15 to the packaging material wall 2 has a greater distance than the outer region 17 of the base region 15.
- Packaging material wall 2 facing side formed. 2) in approximately the shape of an "8."
- a through hole 23, 24 is formed in the recess 20, which has connection from inside the package 20, each of the two through-holes 23, 24 is surrounded by a tower-like elevation 25, 26 which is circular in plan view, as best seen in FIG. 4, each of the two elevations 25, 26 has an inlet radius 27. wherein the upper end face 28, 29 of the elevation 25, 26 runs at a level which is just below the height of the base region 15 immediately adjacent to the depression 20.
- elevations 25, 26 can also extend up to the level of the base area 15 in the central area 16, or even beyond.
- Edge area 12 comes up. Furthermore, on the side facing away from the packing material wall 2 of the base body 11, a preferably round recess 32 is formed, which covers the two through holes 23, 24, and in which a filter element 34 is attached in the form of a nonwoven or the like.
- the nonwoven fabric 34 serves to prevent food particles from entering and clogging the through holes 23, 24 when the particle size is smaller than the diameter of the through holes 23, 24.
- a sealing agent in the form of a thin silicone oil layer 36 is applied in the region of the base region 15.
- the silicone oil layer 36 serves as a sealing and connecting means between the main body 11 and a likewise preferably round trained valve membrane 40.
- the diameter of the valve membrane 40 is slightly smaller than the inner diameter, which is bounded by the edge region 12 of the base body 11.
- the valve membrane 40 is also made of plastic and is flexible to a certain extent due to the selected thickness.
- a constriction 41 running around in the exemplary embodiment is integrally formed on the main body 11 on the inside of the edge region 12.
- a circumferential constriction 41 are also Only partially arranged retaining fingers or the like conceivable.
- the pressure relief valve 10 described so far works as follows: During the Lagungsreaes by the
- Valve membrane 40 can escape. From there, the gas passes through the perforations 5 to the outer packaging or the ambient air. As soon as the overpressure has been relieved, the valve membrane 40, starting from its edge region, rests against the main body 11 again, wherein the silicone oil layer 36 finally causes a seal due to adhesion forces, which also prevents the entry of ambient air into the interior of the package.
- the lifting or lifting of the valve membrane 40 is facilitated by the fact that in the central region 16, in which the recess 20 is located, the distance of the base region 15 to the valve membrane 40 due to the concave design of the base region 15 is relatively large such that the adhesion forces (due to the stiffness of the valve membrane 40) between the valve membrane 40 and the base body 11, relative to the outer region 17, are reduced. As a result, the lifting of the valve diaphragm 40 in the region of the tips 43, 44 is supported.
- the pressure relief valve 10 described so far allows gas already at a relatively low (compared to the environment) Overpressure escapes from inside the package.
- the overpressure valve 10 also seals off particularly well from the outside, since the atmospheric pressure acting on the valve membrane 40 via the perforations 5 additionally presses the valve membrane 40 onto the two elevations 25, 26 and thus closes the through-holes 23, 24. Furthermore, the circumferential depression 30 causes silicone oil to collect in this region or serves as a reservoir for silicone oil, which can thus be supplied to the valve membrane 40 again, so that a relatively uniform wetting of the valve membrane 40 on the base region 15 faces Side with the silicone oil.
- a depression 52, 53 tapering outwards extends from the depression 51 on each side. Outside the two depressions 52, 53, the base region 55 of the main body 56 is planar or flat. The fact that the two depressions 52, 53 emanate from the two tips 57, 58 of the also "8" -shaped recess 51, a particularly easy lifting of the valve diaphragm 59 is also made possible in the second pressure relief valve 50.
- Relief valve 60 the recess 61 corresponding to the first pressure relief valve 10 is circular, but only extends to the edge of the recess 62 zoom.
- the relief valves 10, 50, 60, 65 and 66 described so far can be modified or modified in many ways, without departing from the spirit of the invention. This consists, in particular, of facilitating the lifting of the valve membrane by increasing the distance between the valve membrane and the main body by means of a special design of the respective base region or of the overlap region with the valve membrane.
