Definitions

  • the present invention relates to a cap of the type used on aerosol cans.
  • a cap has a skirt which is adapted to engage with the can, so as to enclose a valve mechanism on top of the can.
  • Aerosol cans have a cylindrical main body part closed at the top by a domed part which centrally carries the valve mechanism.
  • Steel cans have been made with an upstanding peripheral flange where the cylindrical part joins the domed part so as to define an annular recess around the can.
  • the skirt of the cap seats in the recess and usually snap engages into position.
  • a can and cap of this type are disclosed in U.S. Patent No. 3565295.
  • the overall shape of the assembled can and cap is basically cylindrical, but the cap is slightly inset radially relative to the can body and the flange separates the can body from the cap.
  • Such a can bas a peripheral lip radially inset from the can body and surrounding the domed part.
  • a cap for such a can is injection moulded from plastics material and the skirt has internal projections near the rim. These projections snap-engage with. the lip on the can and the circular end wall of the skirt seats on a curved annular shoulder of the can so that the peripheral wall of the can is substantially flush with the cylindrical wall of the body of the can.
  • the present invention provides a flush fitting type cap which can withstand high top loads, is easy to mould and does not have unsightly sink marks.
  • a flush-fitting type aerosol can cap of hollow cylindrical form having a top and a skirt of substantially constant cross-section defining a substantially smooth external cylindrical surface of the cap, the skirt being provided near its rim with integral internal projecting means for resiliently engaging beneath a lip on an aerosol can and being provided with an integral internal projecting seat spaced inwardly of the cap away from the projecting means for seating on the lip, wherein the seat is defined by an annular end wall of a flange extending from the internal wall of the skirt inwardly towards the rim of the cap at an acute angle as viewed in section to define an annular space between the flange and the internal wall of the skirt.
  • the flange may be continuous or discontinuous, i.e. defined by discrete portions.
  • U.S. Patent Specification No. 3565295 has an additional internal skirt depending from the top of the cap within the main skirt.
  • This internal skirt has an internal annular flange which engages with a lip on an aerosol can adjacent to the valve mechanism.
  • This flange is sufficiently thin and flexible to be deformed by the lip when the cap is engaged with the can, so as to form a seal with the lip.
  • the face of the flange which faces the internal skirt engages with the lip to facilitate such deformation.
  • the flange is not intended to support the cap under top load and is so constructed that it could not do so.
  • the additional skirt itself would increase the resistance of the cap to top load, but the provision of the extra skirt greatly increases the cost of the cap.
  • This publication tends to lead a reader away from the concept of supporting a cap against top load by means of an internal flange, since the flange depicted clearly could not serve this function.
  • the cap 11 shown has a skirt with a smooth cylindrical outer surface 12 and a flat top 13.
  • the cap is fitted to an aerosol can so that its surface 12 is substantially flush with the cylindrical outer surface of the can 14 ( Figure 1).
  • the cap is a one-piece plastics injection moulding.
  • the aerosol can 14 has a cylindrical body 24 with a substantially smooth external surface.
  • the top of the body is closed by a doomed port 10 which carries at the top a valve assembly 9.
  • the domed part has a lip 26 where the domed part joins the body part.
  • the lip is radially inset from the exterior surface of the cylindrical body. This part of the can is shown greatly enlarged in Figure 4.
  • the cap also has a cylindrical internal surface 15 and, near the rim 16 of the cap, this internal surface is provided with a multiplicity of small projections or pips 17 arranged in circumferential alignment. Spaced inwardly of the cap away from the pips 17 is an internal annular flange 18. This flange extends towards the rim 16 and towards the axis of the cap at an acute angle, as viewed in cross-section, to the internal cylindrical wall 15. An annular space 19 is thereby defined between the flange and the internal cylindrical wall.
  • the flange 18 has its surface 20 adjacent the internal wall 15 angled at about 10° to the wall 15, as viewed in cross-section, whereas the opposite wall 21 of the flange is angled at about 15° to the wall 15, the thickness of the flange increasing away from the internal wall 15.
  • the maximum angle between the surface 20 and the wall 15 is 30°.
  • the end face of the flange 18 is formed with a V-section groove 23.
  • a part of the aerosol can 14 is shown in this Figure, the can having the main wall 24 formed near the rim with an annular recess 25 and at the rim with the lip 26.
  • the cap is fitted on the can by resilient engagement of the pips 17 on the underside of the lip 26.
  • the maximum extent to which the cap can be forced down onto the can is limited by engagement of the grooved end face 23 of the flange 18 with the top of the lip 26.
  • the grooved formation permits the lip to extend into the groove to reduce the risk of the flange being forcibly deflected so as to become ineffective.
  • the arrangement is such that the reaction to the force exerted by a top load is transferred along the flange to the skirt so that a top load of at least 60kg can be supported by the flange.
