Definitions

  • the invention relates to a cap for an aerosol can by which a vent for dispensing a content of the aerosol can is protected.
  • EP 1 247 758 A1 discloses a cap for an aerosol can which can be clipped to the aerosol can.
  • the cap comprises an actuation head arranged inside a circumferential cap wall which is connected to the cap wall via breakable bridges. When the actuation head is broken from the cap wall the actuation head can be connected with a stem of a vent of the aerosol can.
  • the actuation head comprises an outlet channel protruding radially outwards at a level above the upper rim of the cap wall when not actuated.
  • the actuation head can be pushed downwards for opening the vent and discharging the content of the aerosol can via the outlet channel, wherein the protruding outlet channel engages into a recess inside the cap wall so that the actuation head can perform a full actuation stroke without being blocked by the cap wall.
  • An aspect of the invention is directed to a cap for protecting a vent of an aerosol can, comprising a circumferential cap wall for covering a lateral area of the vent and an actuation head for actuating the vent in a mounted state, wherein the actuation head is connected with the cap wall via breakable bridges in an attached state, wherein the actuation head comprises a cover for covering a stem of the vent in the attached state of the actuation head, an inlet channel for being mechanically and fluidly connected with the stem in the mounted state of the actuation head and an outlet channel fluidly connected with the inlet channel and protruding radially outwards from the cover for discharging a content of the aerosol can radially outside the cap wall, wherein the cap wall comprises a recess for receiving the outlet channel in mounted state of the actuation head in a lower discharge position, wherein the actuation head comprises a stopper for blocking a turning of the discharge channel out of the recess of the cap wall in mounted state of the actuation
  • the cap wall and the actuation head can be one-piece in the attached state, so that the whole cap can be produced one-piece by plastic injection die casting in a cost efficient manner.
  • the cap can be connected to the head of the aerosol can, so that the vent of the aerosol can is arranged inside the cap and protected by the cap wall as well as by the actuation head which may cover the vent.
  • the aerosol can and the connected cap can constitute an aerosol can arrangement which can be shipped and sold without the risk that the vent is opened accidentally.
  • the actuation head can be detached from the cap wall by breaking the bridges of the actuation head while being connected with the cap wall in the attached state.
  • the stem of the vent is freely accessible after braking the actuation head from the cap wall, which is still connected to the aerosol can, and allows to remove the actuation head from the space enclosed by the cap wall.
  • the stem of the vent may be connected to a specific discharging device for discharging the content of the aerosol can, which is quite common in the hair dressing field. However, it should still be possible to discharge the content of the aerosol can without an additional discharging device.
  • the removed actuation head can be utilized for actuating the vent of the aerosol can by connecting the inlet channel of the actuation head with the stem of the vent providing the mounted state of the actuation head.
  • the actuation head is connected to the cap wall via bridges in the attached state, while the inlet channel of the actuation head is disconnected from the stem in the attached state of the actuation head.
  • the inlet channel of the actuation head is connected to the stem of the vent in the mounted state.
  • the vent can be opened by pushing the actuation head and the stem downwards, so that the vent opens and the content of the aerosol can flows via the vent and the inlet channel to the outlet channel of the actuation head, where the content leaves the actuation head at an outlet opening of the outlet channel.
  • the protruding outlet channel is received by the recess of the cap wall, so that a full actuation stroke can be performed without being blocked by the upper edge of the cap wall.
  • the discharge channel is arranged at a level above the upper edge of the cap wall, when the actuation head is not pushed down into its discharge position but left in the elevated closing position, due to the restricted building space in axial direction of the cap and the providing of a significant high actuation stroke.
  • the intended actuation stroke requires a significant axial distance between the higher closing position and the lower discharge position of the discharge channel, which particularly corresponds to the maximal axial displacement of the stem inside the vent. Due to the stopper outside the cover and below the outlet channel it is prevented, that the outlet channel turns in the peripheral direction into a position where the outlet channel is displaced with respect to the recess.
  • the outlet channel can be positioned within a peripheral angle where the outlet channel is aligned in line with the recess in the cap wall.
  • the outlet channel meets the upper rim of the cap wall next to the recess, which would block the downward movement of the actuation head and would prevent reaching the discharge position of the actuation head.
  • the stopper would abut at the material of the cap wall bordering the recess in the cap wall. Even when the outlet channel is positioned outside the recess and above the upper rim of the cap wall, the stopper is still positioned inside the recess for blocking a turning of the outlet channel away from the recess.
  • the outlet channel is particularly positioned as high as possible, so that the outlet channel would be arranged above the upper rim of the cap wall automatically, when a part of the actuation head should protrude from the level of the upper rim of the cap wall. It is further used the insight that the stem of the vent is usually axially symmetrical, so that a connection technique for connecting the actuation head with the stem may allow a turning of the actuation head around the longitudinal axis of the stem.
  • the stopper blocks a turning of the actuation head by abutting the material of the cap wall bordering the recess, so that the actuation head together with the outlet channel may protrude upwards from the level of the upper rim of the cap wall, while a blocking of the intended actuation stroke is prevented at the same time.
  • the stopper prevents a blocking of the intended actuation stroke and enables a facilitated mounting and actuating of the actuation head, so that an easy and cost efficient handling of discharging an aerosol can is enabled.
  • the cover of the actuation head may comprise a circumferential cover wall, which is closed at the top by a top wall providing a top face pointing upwards.
  • the inlet channel may be provided not centrally to the center of area of the top wall but offset, particularly along the cover wall. Particularly, the cover wall may provide a part of the inlet channel.
  • the flow cross section of the inlet channel may be bordered partially by the cover wall.
  • the outlet channel may be provided along the top wall, wherein the outlet channel penetrates the cover wall, so that a part of the outlet channel protrudes from the cover wall.
  • the top wall may provide a part of the outlet channel.
  • the flow cross section of the outlet channel may be bordered partially by the cover wall.
  • the upper face of the protruding part of the outlet channel may be mainly in the same plane as the nearby part of the top face of the top wall.
  • the inlet channel may be aligned mainly in axial direction, wherein the outlet channel is aligned mainly in radial direction.
  • the inlet channel and the outlet channel are connected with each other so that the flow cross section of the inlet channel may communicate with the flow cross section of the outlet channel.
  • the discharged content of the aerosol may perform a deflection by mainly 90°, when the content flows from the inlet channel to the outlet channel.
  • the stem of the vent When the actuation head is in its attached state and connected to the cap wall via the breakable bridges, the stem of the vent may extend into a free volume inside the cap of the actuation head radially offset to the inlet channel.
  • the vent is not only protected by the cap wall but also by the cover of the actuation head.
  • the inlet channel When the inlet channel is connected to the stem of the vent in the mounted state of the actuation head, the actuation head is displaced in radial direction with respect to its position in the attached state. Since the majority of the outlet channel or the whole outlet channel can be located radial inside the cap wall, the packaging size of the cap can be small in the attached state. Due to the radial displacement of the actuation head between the attached state and the mounted state the outlet channel may significantly protrude from the cap wall in radial direction for facilitating the discharge of the aerosol content without soiling the cap or the aerosol can.
  • the aerosol can is mainly cylindrical designed, so that the aerosol can and the cap comprise a mainly circular cross section perpendicular to its longitudinal direction.
  • An "axial” direction is understood as a direction in the longitudinal direction of the aerosol can and/or the cap or cap wall.
  • the cover of the actuation head may or may not comprise a circular cross section, wherein an axial direction with respect to the actuation head is understood as a direction parallel to the axial direction of the aerosol can or the cap.
  • a "radial direction” is understood as an direction perpendicular to the respective axial direction of the considered part.
  • the stopper is arranged outside the cover and below the discharge channel, wherein the stopper is positioned completely radially inside the cap wall in the attached state of the actuation head and inside the recess in the mounted state of the actuation head. Since the stopper cannot contact the cap wall in radial, axial or tangential direction in the attached state of the actuation head, the actuation head can be positioned in a lower sunken position in the attached state with respect to the lower discharge position of the actuation head in the mounted state, so that the packaging size of the cap can be reduced and the vent of the aerosol can be better protected.
  • the stopper When the actuation head is in its mounted state, the stopper is arranged at least partially over the full actuation stroke of the actuation head inside the recess of the cap wall for blocking a displacement of the actuation head in peripheral direction and keeping the outlet channel in a common peripheral angel with the recess of the cap wall enabling the axial movement of the outlet channel over the full actuation stroke inside the recess.
  • the extension of the stopper in radial direction may be significantly smaller than the extension of the outlet channel in radial direction.
  • the stopper is connected with the cover as well as with the outlet channel, wherein particularly the stopper fills a corner between the cover and the outlet channel.
  • the stopper is provided as a part protruding downwards from the outlet channel in a restricted part in radial direction of the protruding part of the outlet channel, so that the stopper is only provided along a radial part of the outlet channel for guaranteeing that the stopper is arranged within the recess of the cap wall in the mounted state of the actuation head.
  • the connection of the outlet channel with the cover is improved. Particularly it is possible to apply a significant force at the free end of the outlet channel for braking at least one bridge in the attached state of the actuation head without breaking the outlet channel.
  • the stopper is formed as a flat flap.
  • the thickness of the stopper may correspond mainly to the wall thickness of the outlet channel and/or to the wall thickness of the cover. A large material accumulation for providing the stopper may be prevented so that the risk of shrink holes in the stopper is prevented.
  • the design of the actuation head may be optimized for plastic injection die casting due to the flat design of the at least one stopper.
  • the outlet channel comprises two side walls pointing in mainly tangential direction of the cap wall, wherein two stoppers are provided at each one of the different side walls, wherein particularly each stopper forms a common face with the associated side wall. Due to the two stoppers spaced to each other in circumferential direction the outlet channel is further stiffened. Particularly a turning of the outlet channel around its radial longitudinal axial is prevented. Further it is possible, that no part of the outlet channel protrudes in tangential direction from the plane of the associated stopper in a direction away from both stoppers, so that no part of the outlet channel is present which may abut the upper rim of the cap wall and block the axial movement of the outlet channel within the recess of the cap wall.
  • the stopper protrudes from the outlet channel in tangential direction so that the whole clearance between the outlet channel and the material of the cap wall bordering the recess can be used by the outlet channel. The risk that the outlet channel could be clamped in the recess is prevented.
  • the stopper comprises a stop face pointing downwards for butting at a rim of the recess in the lower discharge position of the actuation head. It is not necessary providing slits or further recesses for receiving the respective stopper. Instead of letting the outlet channel abutting the rim of the recess in the lower discharge position, it is the at least one stopper abutting the rim of the recess in the lower discharge position.
  • the recess is designed such that the rim of the recess pointing upwards is positioned low enough that the stopper only abuts the rim when the intended full actuation stroke of the actuation head is performed.
  • the cover of the actuation head is connected with the cap wall via two breakable first bridges arranged at opposing sides of the cover in the attached state, wherein the first bridges are arranged in line with a swivel axis aligned between the inlet channel and the protruding part of the outlet channel outside the cap wall.
  • the first bridges may be designed as long bars with a small cross section, so that the first bridges can be easily broken.
  • the first bridges can be twisted by torsion so that the actuation head can be swiveled around the swivel axis provided by the longitudinal direction of the mainly coaxial arranged first bridges.
  • the first bridges can be weaken and finally broken by easily swiveling the actuation head back and forth.
  • the swivel axis provided by the first bridges is provided such, that enough space is present inside the volume bordered by the cap wall that the actuation head may swivel by a significant angle until the first bridges are finally broken.
  • the swivel axis may be provided such, that the inlet channel or the cover wall does not hit the stem of the vent.
  • the swivel axis is positioned such, that the cover meets the cap wall of the aerosol can before the inlet channel or the cover would meet the stem.
  • the position of the first bridges and the swivel axis in axial direction as well as in the plane perpendicular to the axial direction is correspondingly chosen.
  • the actuation head may be swiveled by applying a force to the free end of the outlet channel upwards and downwards. The breaking of the bridges for removing the actuation head out of the attached state is facilitated.
  • the cover comprises a depression for being pressed by human finger at a top face of the cover, wherein the depression is located at a part of the top face beyond the swivel axis and the protruding part of the outlet channel outside the cap wall.
  • a user may apply a force at the free end of the outlet channel upwards and a force at the depression in the top wall of the cover simultaneously for increasing the torque applied to the first bridges.
  • the stiffness of the first bridges is higher at the first swivel movement of the actuation head than afterwards, since the first swivel movement of the pump already provides significant weakening of the first bridges.
  • the breaking of the first bridges is facilitated by the depression which provides an intuitive increase of the applied forces and the provided torque to the first bridges.
  • the discharge channel of the actuation head is connected with the cap wall within the recess via a breakable second bridge, particularly arranged below the discharge channel, in the attached state.
  • the second bridge is provided significantly spaced to the first bridges so that a swiveling of the actuation head by accident can be prevented.
  • the second bridge can be broken by applying a sufficient force to the free end of the outlet channel upwards and/or by turning the actuation head back and forth by an amount provided by the clearance of the outlet channel within the recess of the cap wall.
  • the alternate it is possible to provide one or two second bridges aligned in tangential direction between the outlet channel and the rim(s) of the recess pointing in tangential direction.
  • the longitudinal extension of the second bridge is larger than the longitudinal extension of the first bridge, so that the second bridge can be easier broken by applying forces in longitudinal direction than the first bridge which should be weaken by twisting and applying a torque.
  • a space is provided between the discharge channel and a rim of the recess for inserting a tool and/or a human finger for swiveling the discharge channel upwards above the cap wall in order to break the second bridge.
  • the tool or the finger can be inserter between the rim of the recess pointing upwards and a wall of the outlet channel pointing downwards. This enables a good grip for a user for applying a significant force for breaking the second bridge.
  • a gap is provided between the cover and the cap wall for turning the actuation head when the discharge channel runs above the cap wall in order to break bridges.
  • the gap between the cover of the actuation head and the cap wall is at least so large that the actuation head can swiveled by an angle big enough that the outlet channel is aligned in a direction by which the outlet channel points above the upper rim of the cap wall.
  • the actuation head can be swiveled so far in a first step that the actuation head can be turned around an axial axis in a second step without being blocked by the outlet channel abutting the edge of the recess in the cap wall. This facilitates the breaking of the bridges.
  • the inlet channel of the actuation head comprises a fastening means, particularly a clip connector, for fastening the actuation head with the stem of the vent in the mounted state of the actuation head, wherein the inlet channel comprises a, particularly annular, press face for pressing the stem downwards into an open state, wherein the press face is different from the fastening means.
  • the inlet channel can be connected with the stem such that the inlet channel is mainly coaxially arranged to the stem by means of the fastening means.
  • the fastening means may provide an axial clearance with the stem.
  • the stem may comprise a circumferential notch, into which a snap tab of the fastening means, which is designed as clip connector, is inserted.
  • the fastening means may be rounded at its free end for facilitating the fastening. Since the pressing force for pressing the stem downwards is not provided by the fastening means but by the press face of the inlet channel, it is prevented that a significant force aligned downwards has to be applied via the fastening means, so that it is prevented to impair the connection of the fastening means with the stem or to impair a proper application of the provided press force.
  • the press face can be provided by a step due to a change of the inner diameter of the inlet channel.
  • the bridges comprise a cross section, which is small enough for being broken by hand and big enough for allowing a mass flow during plastic injection die casting.
  • a ratio of a diameter d of the bridge to a material thickness s of the cover is 0.1 ⁇ d/s ⁇ 1.0, preferably 0.3 ⁇ d/s ⁇ 0.8 and particularly preferred 0.5 ⁇ d/s ⁇ 0.6. This ratio may provide a cross section of the bridges, which is small enough for being broken by hand and big enough for allowing a mass flow during plastic injection die casting. This leads to a facilitated production process without hindering the breaking of the bridges.
  • the cap wall is mainly annular formed except within a limited peripheral angle, where the recess is provided within a recessed circumferential part, wherein the discharge channel is arranged within an outer diameter of the cap wall in the attached state of the actuation head, wherein particularly the discharge channel terminates at the outer diameter of the cap wall in the attached state of the actuation head.
  • the circumferential part of the cap wall, where the recess is located may be a straight secant or concave rounded.
  • the outlet channel may protrude from the cap wall outwards even in the attached state of the actuation head without increasing the packaging size of the mainly cylindrical cap.
