Definitions

  • the invention relates to a closure for a spray can, consisting of a plate for holding the valve of the spray can, with a central body part for receiving the valve and an annular groove surrounding the central body part, formed by flanging the outer edge part of the plate, in which one Gasket is arranged and which serves to accommodate the opening edge of the spray can to which the plate is clipped.
  • the middle body part 2 after inserting the seal 3 into the annular groove 4 of the plate 1 and placing the plate 1 on the outwardly rolled opening edge 5 of the spray can 6 , wherein the annular groove 4 of the plate 1 overlaps the opening edge 5 - by so-called «clinching» radially outwards under the opening edge 5 of the spray can 6 to the clinch diameter D c to seal the plate 1 to the spray can 6.
  • the spreading head of the clinching tool lies against an outer surface 7 of the edge part 8 forming the annular groove 4 as an abutment and projects into the body part 2 up to a predetermined clinching height Hc.
  • the seal thickness Tg can have the following fluctuation ranges:
  • the thickness T m of the plate material can have the following values, for example: With the radii R c and R b remaining the same, the clinch height Hc should therefore be set approximately as follows:
  • the dimensions of the plate flange 9 resulting from the encircling of the edge part 8 of the plate 1 and of the lower section 10 of a protective hood 11 or an actuating attachment which engages under it and which engages with the plate flange 9 are closely related to these variable sizes which serve to securely seal the compressed gas pack becomes. You can choose between two options:
  • the height H u of the lower section of the protective hood must be chosen so that the section 10 even in the smallest space with the height D s between the free edge of the to reduce the storage Flange 9 and the top of the spray can 6 fits, since the height Ds changes depending on the thickness T m of the plate material and the thickness Tg of the seal 3. There are therefore cases in which the lower section 10 does not completely fill the gap D s between the flange 9 and the top of the spray can. This is undesirable for optical reasons.
  • the invention is based on the object of specifying a plate of the generic type which, regardless of changes in the thickness of the seal and plate, reduces the storage effort on the part of the bottler and the downtimes of the bottling plant.
  • this object is achieved in that the annular groove is provided with a spacing device which bears against the gasket and which is shaped in accordance with the material thicknesses of the plate and gasket assigned to it such that the distance from one another as an abutment for the clinching tool when the plate is clipped onto the opening edge of the Aerosol-serving outer surface of the flanged edge part from the opening edge after the clinking when choosing a plate and a seal with the dimension resulting from the shape of the spacing device and the assigned material thicknesses of plate and seal has a constant value predetermined for all material thicknesses of plate and seal.
  • the clinch height H c and the height H s of the plate flange remain the same for all thicknesses of the plate material and the seal, since different thicknesses of plate material and seal are compensated for by appropriate design of the spacer device.
  • the bottler therefore does not need to change the clinching tool regardless of the thickness of the plate material and seal.
  • he can use protective hoods or actuating attachments in which the height Hu of the lower section 10 is constant and equal to the gap height Ds, so that the cost of warehousing is also reduced.
  • the spacer device preferably has at least one projection in the annular groove.
  • a projection can be formed in a simple manner in the shaping of the plate or in the later assembly of the plate by the valve supplier.
  • the projection can thus be formed by a recess in the outer surface of the edge part of the plate forming the annular groove. This is simply pressed into the plate material in the manner of a bead.
  • the spacer device can then have cup-like depressions or radial ribs on the bottom of the annular groove. At the same time, these stiffen the plate material in the ring groove.
  • ribs can also be formed in a simple manner by radial depressions in the outer surface of the edge part of the plate forming the annular groove.
  • the spacer device can have a projection which extends at the bottom of the annular groove in its circumferential direction. Such a projection, even if it is formed as a continuous circumferential depression in the outer surface of the edge part of the plate forming the annular groove, is not excessively deformed by the clinch pressure which is later exerted on the plate.
  • the spacer device has a projection which extends on the radially inner side wall of the annular groove in the circumferential direction thereof.
  • Another embodiment can consist in that the spacing device is formed by an oblique wall section of the annular groove.
  • the spacing device is formed by an oblique wall section of the annular groove.
  • FIG. 2 corresponds to those according to FIG. 1, the same reference numbers are used in FIG. 2.
  • Parts of FIG. 2 that deviate from FIG. 1 are provided with reference numbers that are increased by 20 compared to the reference numbers according to FIG. 1.
  • depressions 12 are embossed in the ridge of the edge part 28, which appear as projections 13 on the bottom of the annular groove 24.
  • the depressions 12 and projections 13 are distributed at preferably uniform intervals over the circumference of the plate 21.
  • the depth of the recesses 12 or the height of the projections 13 is chosen so that, together with the respective thickness T m of the plate material and the thickness Tg of the sealing material, it always gives the same constant distance value x, at which H c and Fixed flange height H s, the distance D s always has the same value, so that the height H u of the lower section 10 of the protective hood 11 or a corresponding actuating attachment for the valve of the spray can can can always be chosen to be the same as the distance D s by the Fill the space between the edge flange 29 of the plate 21 and the top of the spray can 6 in all cases with seals 23 and plate materials of different thicknesses completely through the section 10, this section 10 having a radially inwardly projecting projection 14 which snaps under the edge flange 29.
  • the height H o of the upper section of the protective hood 11 is always given the same value, which is the same as the flange height H s of the edge flange 29. Storage of protective hoods 11 with different dimensions of H o and H u is therefore not necessary.
  • a recess 12 ' which is continuous in the circumferential direction and in which a projection 13' which extends correspondingly in the circumferential direction of the plate at the bottom of the annular groove 24 results.
  • the upper edge of the plate shown in this case as dashed line 15 is somewhat lower.
  • the protective hood 11 remains in the same position since it continues to be supported on the curved surface 27 on the outside of the edge part 28. Since the clinching tool is usually not only on the surface 7, i.e. The clinching depth Hc remains unchanged on the ridge of the edge part 28 but also on the surface 27 lying somewhat further outside.
  • the seal 23 is a film seal, i.e. a section cut from a tube, which is pushed over the central body part 22 of the plate 21 into the annular groove 24, so that it not only rests against the bottom of the annular groove 24, but also against the inner side wall 16. In the area of this side wall 16 there are consequently large sealing surfaces. However, an injected seal 3, as shown in FIG. 1, can also be provided.
  • a seal in the form of an annular disk can be used, which only bears between the projection 13 ′ and the ridge of the opening edge 5.
  • the embodiment according to FIG. 3 differs from that according to FIG. 2 only in that instead of the approximately frustoconical or conical recesses 12, those in the form of radial grooves 12 "in the ridge of the edge part 28 are formed with corresponding radial ribs 13" at the bottom of the annular groove 24 are. These grooves 12 "and 13" simultaneously stiffen the bottom of the annular groove 24. Die Dimensions are the same as those of the embodiment of FIG. 2, while the protective hood 11 is omitted to simplify the illustration.
  • FIG. 4 differs from that of FIG. 2 only in that instead of the recesses 12 and projections 13, a recess 12 "and a projection 13" are provided, which are located on the radially inner side wall 16 of the annular groove in its circumferential direction Extend above the lower half of the circular cross section of the rolled opening edge 5 of the spray can 6, so that the abutment surface 7 in the area of the ridge of the edge part 28 of the plate 21 continues to maintain its conventional shape. In the area of the depression 12 ′′ and the projection 13 ′′, the conventional contour of the edge part 28 is drawn in by dashed lines.
  • the embodiment according to FIG. 5 differs from that according to FIG. 2 only in that the cross-sectional contour of the edge part 28 of the plate 21 forming the annular groove 24 is approximately V-shaped above the lower half of the opening edge 5 of the spray can 6 which is circular in cross section, so that the radially inner wall 16 of the annular groove 24 forms an inclined wall section 17 which acts as a spacer device.
