Definitions
- the invention relates to a protective cap for container discharge valves, in particular beer taps for draught beer kegs, comprising a top plate and a skirt formed integrally therewith and provided with inwardly resilient catches, preferably arranged pairwise or groupwise in the circumferential direction and adapted to abut on the underside of a collar on the discharge valve to prevent the cap from being removed without visual damage thereto.
- Such protective caps primarily functioning as a pilferproof seal for draught beer kegs are disclosed in DE-A-34 17 812 and DK-B-158 083, the latter of which describes a design particularly appropriate for die-casting and additionally provides a satisfactory water- and dust-tightness in its position of use.
- the catches extend obliquely upwards from the inner side of the skirt at an angle with the skirt which when unloaded is approximately 45°.
- This design of the catch is based on the prerequisite that the valve collar of certain standard designs of draught beer kegs has an obliquely inwards and downwards directed underside so that the catch from the position it occupies, substantially parallel to the inner side of the skirt when the cap upon mounting is pressed down over the collar, unimpededly may be pivoted inwardly into its position of use and at the same time the inwards directed upper edge of the catch still abuts on the underside of the collar, thereby substantially retaining the cap in the axial direction.
- the valve collar of certain standard designs of draught beer kegs has an obliquely inwards and downwards directed underside so that the catch from the position it occupies, substantially parallel to the inner side of the skirt when the cap upon mounting is pressed down over the collar, unimpededly may be pivoted inwardly into its position of use and at the same time the inwards directed upper edge of the catch still abuts on the underside of the collar, thereby substantially retaining the cap
- An object of the invention is to provide a protective cap particularly appropriate for the latter type of draught beer kegs, from which said drawbacks have been eliminated which in practice cause that the prior art protective caps cannot be mounted satisfactorily.
- the catches are substantially plane and approximately perpendicular to the top plate while in a plane parallel to the top plate they extend obliquely inwards from the inner side of the skirt, the upper edge of each catch being substantially parallel to the top plate at a distance therefrom corresponding to the thickness of said collar, whereas the lower edge extends obliquely upwards from the inner side of the skirt so that the axial extension of the inwards directed edge of the catch is substantially smaller than the axial extension at the inner side of the skirt.
- the protective cap according to the invention may be implemented to be secured on valve collars having a plane underside with no possibility of axial displacement after the mounting, and the comparatively short axial extension of the inner edges of the catches entails that the catches may be received even in a comparatively narrow clearance between the collar and a subjacent bead.
- the bevelled cut of the lower edge of the catch entails that the mounting is substantially effected as easy as in prior art caps.
- a further easily mountable design may be obtained in that the lower edge of each catch has a substantially concavely bent course or a course composed of rectilinear sections.
- an improved security against rotation of the cap in relation to the valve collar may further be obtained so as to offer an improved security against non-damaging removal of the cap, also from valve collars which at the circumference as mentioned above has one or more rectilinear chord sections in which the available catches do not engage below the valve collar.
- the cap may be produced in its final shape in one step, in that the top plate is in axial alignment with each of the catches and has a cut-out extending to the edge of the top plate which at the inner edge of the cut-out is connected through a flexural hinge with a sealing flap that prior to the mounting is directed downwards towards the associated catch but which by the mounting of the cap is urged upwards by the valve collar into a position in which it fills up the cut-out.
- Fig. 1 shows one half of the top plate 1 of a preferred embodiment of the protective cap according to the invention.
- the catches are substantially plane and approximately perpendicular to the top plate 1.
- the catches extend obliquely inwards in a radial plane parallel to the top plate 1, from the inner side of the skirt 4 connected with the top plate 1 at an angle of e.g. 55 to 60° with a radius centrally of the flap.
- the upper edge 5 of the catches 3 is substantially parallel to the top plate 1 with the view of abutting on a plane underside of a valve collar, while the lower edge 6 in order to permit the cap to be pressed down over the collar upon mounting extends obliquely upwards from the inner side of the skirt.
- the axial extension of the flap thus becomes considerably smaller at its inner edge 7 than the axial extension at the inner side of the skirt, e.g. smaller than half of it.
- top plate 1 with the cut-outs 2 in axial alignmnet with the catches 3 ensures that the cap may be implemented in its final shape by die-casting in a comparatively simple mould consisting of two parts.
- the top plate 1 is connected through a flexural hinge 8 with a sealing flap 9 projecting downwards in the unloaded condition and which, however, upon mounting the cap on a valve collar is urged upwards to the position illustrated in Fig. 5.
- FIG. 5 illustrates the mounting of the cap on a keg valve collar 10 of the type having a comparatively small thickness and a plane underside and in which a circumferential bead 12 is further mounted on the valve socket 11 at a short distance under the collar 10, so that there is merely a comparatively narrow incision to receive the catches 3.
- valve collars of the type concerned are not always circular but may have one ore more rectilinear chord sections 14.
- the cacthes are, in connection with the pairwise mounting in Fig. 1, formed so that the two catches of each pair converge towards each other.
