Definitions

  • the invention relates to a valve mounting cap according to the preamble of claim 1 (as is known for example from DE-B-2 021 643).
  • Aerosol dispensers are widely used in the packaging of fluid materials, including a variety of both liquid and powder products. These containers are provided with a valve-controlled dispensing opening and are operated by a volatile propellant, which is contained in the container together with the product to be dispensed. Since the propellant has a considerable vapor pressure at room temperature, the product in the closed container is at a pressure above atmospheric pressure.
  • a typical aerosol unit has a hollow cylindrical container which is sealed at one end and provided with an opening for receiving a dispensing valve arrangement at its opposite end.
  • a lid referred to as a mounting cap serves as a closure for the container and as a carrier for the valve arrangement.
  • the mounting cap has an annular bulkhead that surrounds an upstanding, cylindrical, apertured base, called the "dome,” for receiving the valve assembly, a peripheral wall protruding from the peripheral edge of the transverse wall, and a peripheral wall projecting outwardly from the edge of the peripheral wall Ring channel.
  • the annular channel lies over the flange surrounding the container opening, and the lower part of the peripheral wall near the channel is widened outwards against the container wall near the flange.
  • the cap is provided with a seal in the ring channel of the cap.
  • the gasket may be a flat ring cut from resilient material, or may be by flowing in and drying a liquid gasket forming material or, which is preferred, sliding a tubular sleeve onto the peripheral wall into the annular channel as described in European patent applications EP0033626A2 and EP0075287A2 is to be formed.
  • Valve mounting caps are typically sold as complete assemblies in which the valve is secured in the base and is often provided with a product sampling or dip tube attached to the valve.
  • the arrangement may further comprise a valve actuating part or button with a dispensing opening and a structure adapted to the dispensing of the product in question.
  • the empty containers come from different suppliers than the valve arrangements. Therefore, the dimensional tolerances have been standardized to ensure that the flange or flange edge of the container opening and the ring channel of the mounting cap fit together.
  • the product to be dispensed, the propellant through which it is to be dispensed, the container, the mounting cap, the valve assembly and the valve actuator are then brought together to form a complete aerosol dispenser.
  • the mounting cap assembly is loosely inserted into the opening of the container filled with the product, a predetermined amount of propellant is pressed into the container between the mounting cap and the container flange, and then the deformation cap is attached to the container by deforming its peripheral wall below the container flange.
  • the propellant can be filled in quickly because a large area is available between the mounting cap and the container flange. This process is referred to in the industry as "under-the-cap" filling.
  • the removal or immersion tube of the mounting cap arrangement acts like a spring which tends to press the mounting cap out of the container to which the arrangement is loosely connected. Furthermore, the mounting cap arrangement can be detached from the container by vibrations while the container and mounting cap arrangement are being conveyed to the propellant filling head or to the propellant filling station. In order to ensure a better hold of the cap on the container, small depressions are pressed into the inside of the mounting cap circumferential wall in order to form smaller projections on the outside of the circumferential wall (see, for example, DE-B-2 021 643).
  • the fit of some mounting caps may be too loose and the fit of others may be so tight that the protective layers that are often applied to the inside of the container are scratched or the container flange itself is scratched, especially if the container is made of aluminum.
  • the seal is made from a tubular sleeve, as described in the patent applications mentioned, the sealing sleeve is sometimes pressed out of the ring channel of the mounting cap and onto the container flange by the propellant that shoots past it. If the cap is then inserted and attached to the container, indentations in the seal caused by the passage of the conventional known protrusions can lead to leakage paths or cracks in the seal.
  • the invention has for its object to provide a valve mounting cap of the generic type, which avoids impairment of the seal and / or inside of the flange of the container opening during assembly while being easier to manufacture and easier to assemble.
  • the projections according to the invention rest frictionally on the outside of the flange surrounding the container opening. They secure the mounting cap and the valve assembly in position on the container while it is being conveyed to the propellant filling station or another station.
  • the projections are preferably formed by pressing in shallow depressions from the outside of the peripheral edge of the ring channel.
  • the location of the formation of the flat projections on the outer edge of the ring channel of the mounting cap has numerous advantages.
  • the projections lie on the outside of the flange surrounding the container opening, where scratching of the flange or a protective layer can be accepted because this side does not come into contact with the product.
  • the outer edge of the ring channel of the mounting cap is relatively elastic compared to the relatively rigid peripheral wall of the mounting cap, on which projections were previously formed. This elasticity allows the container flange to be clamped in a spring-like manner by the projections, so that a better adaptation to the dimensional tolerances of the flange and cap is possible.
  • the formation of the projections in the mounting cap according to the invention can be brought about by a simple rectilinear reciprocating movement of a tool which is guided past the outer edge of the mounting cap.
  • the device required to form the previous projections in the peripheral wall requires a mechanically complicated radial reciprocating movement of several tools, which have to be stopped with high precision in order to form depressions with a precise depth.
  • the tool required to manufacture the mounting cap according to the invention is not only simpler, but it also enables the desired depth of the depressions to be exactly maintained. Another advantage is that the simplicity of the tool required also allows the formation of the edge recesses long after the production of the mounting cap, so that no separate storage of mounting caps with and without projections is required on the part of the user.
  • the mounting cap shown has an annular transverse wall 10 which surrounds an upwardly projecting cylindrical base 12, the so-called “dome”, for receiving a dispensing valve, not shown.
  • An opening 14 in the upper floor of the dome 12 receives the hollow shaft of the valve on which an actuating part or actuating button is arranged.
  • the annular transverse wall 10 is surrounded by a cylindrical peripheral wall 16 which ends in an annular channel 18 at its upper end. As shown in FIG. 2 (a), the ring channel 18 rests on a toroidal flange 22 which surrounds the opening of the aerosol container 20.
  • the mounting cap is replaced by a (not shown) attached radially outward deformation, which is incorporated into the peripheral wall 16 of the mounting cap after the container has been filled and the cap is attached, as a permanent closure of the container.
  • the outward deformation is an outwardly extending bulge formed by a segmented spreading tool associated with the propellant filling station.
  • a seal 30 made of elastic material ensures a pressure-tight seal between the ring channel 18 of the mounting cap and the flange 22 of the container 20.
  • the seal 30 is shown here as a tubular sleeve, as described in the European patent applications EP0033626A2 and EP0075287A2.
  • parts corresponding to those in Fig. 2 (a) are given the same reference numerals.
  • the outer edge of the ring channel of the mounting cap is provided with at least one projection which is sufficient to bring about a tight fit or a fit with an oversize on the flange of the container, so that the mounting cap is prevented from coming loose from the container while it is leading to the propellant filling and Clamping stations is transported, the former in the case of an "under-the-cap filling" and the latter in the case of a "pressure filling".
  • the firmness of the tight fit is limited, so that the mounting cap can be removed when the propellant is filled.
  • the tightness of the tight fit is also limited in the event that any other treatment requires removal of the mounting cap.
  • the peripheral or outer edge of the ring channel 18 of the mounting cap is provided with a plurality of recesses 40 which are spaced apart in the circumferential direction and form inwardly extending projections.
  • the radially innermost points of the projections lie on a circle, the radius R (see FIG. 3) of which is somewhat smaller than the radius of the radially outermost points of the container flange 22. The difference in dimensions results in a tight fit or an oversize fit when the cap is placed on the container, so that the cap is held on the flange by friction.
  • the cap edge can expand elastically in the radial direction, so that there is a spring preload which improves the clamping effect exerted by the projections 40 on the flange 22.
  • the known design of the projections on the relatively rigid cylindrical peripheral wall 16 of the cap results in a much lower spring preload than the present location of the training. Because of the elastic spring bias caused by the location of the projections 40 on the outer edge of the ring channel 18, the frictional engagement in which the mounting cap is temporarily held on the container is practically independent of different dimensions of the mounting cap and the container flange and is easily adaptable to them . The hold is reliable. Because there are no projections in the peripheral wall 16, the risk of scratching or scarring of the container flange, of protective coatings or of the seal itself is eliminated.
  • the projections 40 can be formed in a wide variety of ways, the easiest and most reliable way is to move a deformation tool axially past the outer edge of the annular channel 18 of the cap and to press depressions into the peripheral edge of the cap.
  • the axial displacement of the tool eliminates the precise stopping of the movement of the tool, as is necessary when the known radial depressions are formed in the peripheral wall 16.
  • the tool is simply moved back and forth past the edge of the cap in order to form indentations of equal depth with high accuracy and reproducibility.
