Definitions

  • the present invention relates to a dispensing closure for a container and to a container with such a closure.
  • closures are typically used for dispensing products contained in a container to which said closure is attached.
  • the products to be dispensed are typically fluid products, especially liquids but also powdered or granular products, e.g. in the food and beverage area, but also in other applications, e.g. for cleaning substances, detergents or other products.
  • the present invention especially relates to a dispensing closure, through which the fluid material, especially a liquid, can be dispensed without the use of pump devices, like e.g. a mechanical pump.
  • the dispensing fluid is typically dispensed from containers through such free flow dispensing closures using gravity.
  • the dispensing closures can be especially used for large or so-called XXL containers, and it is specifically useful for so-called free flow dispensing closures, i.e. closures which do not comprise a pump device.
  • Such a dispensing closure is e.g. known from Wo 2018/171886 Al.
  • the dispensing closure disclosed therein comprises a peripheral wall and a transverse wall being made of deformable material, so that the transverse wall and the peripheral wall are distorted when force is exerted onto a toggle member.
  • the dispensing closure according to the present invention comprises a dispensing unit having a dispensing opening for dispensing a fluid and a first sealing region, the dispensing closure according to the present invention further comprising a base unit having a skirt portion for attaching the base unit to a container, said base unit further having a second sealing region.
  • the dispensing unit is at least partly movable relative to the base unit along an x-direction of the dispensing closure (or at least one part or one element of the dispensing unit is or multiple parts or multiple elements of the dispensing unit are movable relative to the base unit) between a shut-off position, in which the first sealing region comes into sealing contact with the second sealing region, and a dispensing position, in which the first sealing region is at least partly out of contact with the second sealing region thereby providing a through opening for allowing a fluid product or material to pass between the first sealing region and the second sealing region for being dispensed through said dispensing opening.
  • the movement along the x- direction is a movement along or in parallel to a central axis of the closure device, and the movement is linear or essentially linear movement.
  • the dispensing closure according to the present invention comprises a vent channel, said dispensing closure being arranged such that flow of air from an outside of the closure through the vent channel to an interior volume of the container is not possible when said dispensing unit is in its shut-off position.
  • the dispensing unit comprises an operating unit with spring means, said spring means preferably comprising bellows, wherein said dispensing closure is arranged such that said operating unit is biased into the shut-off position by said spring means such that said dispensing unit remains in its shut-off position and/ or moves into its shut-off position when no force is asserted by a user onto said operating unit.
  • said dispensing unit comprises a stem unit being connectable or connected to said operating unit, said stem unit comprising the first sealing region and comprising at least a part of said vent channel.
  • the dispensing closure according to the present invention provides an easy to manufacture device and a closure device which is easy to be operated by a user.
  • the dispensing closure according to the present invention furthermore provides an auto closing function, with the effect that in situations where no force is exerted onto the dispensing closure, especially no force is exerted onto the operating unit of the dispensing unit, the dispensing closure will automatically move into its shut-off position.
  • the dispensing closure also provides the user with an easy control, not only with respect to switching between shut-off position and operating position, but also with respect to a controlled dosing of the fluid material, especially the liquid, to be dispensed.
  • a further advantage of the dispensing closure according to the present invention is that the first and second sealing regions can be used for both stopping a dispensing of liquid and for closing the vent channel without the need to provide separate or additional elements therefore.
  • said operating unit comprises a first part of said vent channel, set first part being preferably a part being close to a vent opening to the outside of the closure, for allowing air to stream in when a liquid material is dispensed, in order to avoid vacuum within the closure.
  • the stem unit comprises a longitudinal middle section, which preferably extends along a central axis of said dispensing closure.
  • Said stem unit preferably further comprises, preferably at first end region, a sealing section, wherein said sealing section comprises said first sealing region.
  • said stem unit comprises, preferably at a second end region, a connection section for connecting said stem unit to said operating unit.
  • said stem unit comprises a second part of said vent channel, wherein said second part of the vent channel extends in a longitudinal direction within the middle section of said stem unit, wherein said longitudinal direction preferably being parallel to a central axis of such a dispensing closure, more preferably the second part of said vent channel extends mainly or partly along the central axis of such a dispensing closure.
  • the stem unit therefore serves and fulfills two functions, namely, on the one hand it allows transferring the force exerted by a user to push or move the stem unit or the dispensing unit into its dispensing position, on the other hand the stem provides at least a major part of the vent channel. This avoids the necessity to provide further and multiple elements, being difficult to manufacture and to assemble, thereby lowering costs for manufacturing and enhancing reliability of the dispensing device.
  • said stem unit preferably a second end region of said stem unit, forms, together with said operating unit, a vent volume, when said stem unit and said operating unit or connected with each other after assembly.
  • vent volume is a part of the vent channel, and in a preferred embodiment the vent channel is in fluid connection with a first part of said vent channel and a second part of said vent channel, thereby connecting the first part and the second part of the vent channel.
  • the first part of the vent channel and the second part of the vent channel extend along different directions.
  • the second part of the vent channel extends in an x direction or parallel to a central axis of the closure, while the first part of the vent channel preferably extends in a direction perpendicular thereto, preferably in a dispensing direction.
  • the vent volume provided between these two parts of the vent channel secures a specifically smooth venting function, especially lowering or reducing flow turbulences, which may have a negative effect on the venting function.
  • said stem unit comprises a third part of said vent channel, wherein said third part extends preferably from said second part of said vent channel in a direction different to said longitudinal direction, preferably in a direction perpendicular to or essentially perpendicular to said longitudinal direction. All elements of the closure are therefore most efficiently utilized for forming the necessary elements for the desired functions, while the vent flow is optimized.
  • closures are typically used for large containers, so-called XXL containers, while the dispensing closure is attached at the side wall of the container.
  • the central axis of the closure extends essentially in a horizontal direction.
  • the first part and the second part of the vent channel extend in the vertical direction when the closure is attached to the container.
  • the air passing from the outside to the vent channel into the closure moves essentially into the opposite direction compared to the liquid to be dispensed, first in an upward direction within the first part of the vent channel, then horizontally within the second part of the vent channel in the stem unit, and finally again in an upward direction.
  • the air passing through the vent channel is therefore kept separate from the liquid to be dispensed over a long distance, being allowed to enter a volume in which also liquid is present only at the end of the third part of the vent channel. This essentially assures a smooth venting capability, reducing turbulences to a large extent, so that also a smooth dispensing of liquid is possible.
  • said dispensing unit comprises a dispensing channel which extends, starting from the dispensing opening, at least partly in a radial or essentially radial direction of the dispensing closure, said radial direction of the dispensing closure being perpendicular to a central axis of said dispensing closure.
  • said dispensing unit comprises a first part of said vent channel, wherein said first part of said vent channel extends at least partly in parallel to said dispensing channel.
  • the flow of liquid during dispensing is realized antiparallel to the venting flow, while being kept separate from each other for a long extension, thereby even enhancing the above-mentioned functions and the undisturbed flow of both the liquid to be dispensed and of the air to be introduced into the container.
  • said dispensing unit comprises a vent channel having a first part, a second part and a third part, the second part extending in a longitudinal direction, preferably in parallel to a central axis (A) of said dispensing closure, while said first part and said third part extend, from opposing ends of the second part of the vent channel into directions being different from the longitudinal direction of the second part, preferably perpendicular or essentially perpendicular to the longitudinal direction of the second part, while the first part extends from said second part in a different direction than said third part, preferably into an opposite or essentially opposite direction.
  • the first part of said vent channel extends in a vertical direction perpendicular to a central axis of said dispensing closure, wherein the first part of said vent channel extends from an outer vent opening which opens to the exterior of the dispensing closure for allowing air to stream into and through the vent channel.
  • the dispensing closure comprises a third part of said vent channel, which extends in a vertical direction perpendicular to a central axis of said dispensing closure, wherein the third part of said vent channel extends from an inner vent opening which opens to an interior of the dispensing closure for allowing air to stream out of the vent channel.
  • said outer vent opening is, with respect to the vertical direction, positioned below a central axis of said dispensing closure and/ or said inner vent opening is, with respect to the vertical direction, positioned above a central axis of said dispensing closure.
  • the above-mentioned functions of the dispensing closure are optimized. Notably, it is ensured that, during operation and when the closure is attached to the container, preferably, as mentioned above, on a side of the container, the air is vented through the vent channel along the central axis of the stem unit, while before entering the middle or second part of the vent channel, being directed in an upward direction, and after leaving the middle or second part of the vent channel, being again directed in an upward direction, so that an entry opening or an outer vent opening is at the lowest vertical position, while the opposite opening or an inner vent opening, through which the vent air leaves the vent channel, is at the highest vertical position of the vent channel. It been shown that such an arrangement leads to specifically positive results and a smooth functioning of the dispensing closure, especially a smooth dispensing of liquid.
  • said spring means preferably realized at least partly by bellows, extend about a predetermined length along a central axis of the dispensing closure, wherein said predetermined length of said spring means and the vent channel are dimensioned such that the vent channel or a middle part of the vent channel extends at least over 50%, more preferably at least over 80% into said predetermined length of said spring means, when said dispensing unit is in its shut-off position.
  • said operating unit and said stem unit are designed such that they can be connected to each other by snap fitting.

  • said operating unit is designed such that it comprises a ringlike contact portion being in direct or indirect contact with the base unit, preferably with the deck portion of the base unit.
  • a further specific advantage is that those elements of the dispensing unit, comprising the spring means, especially the bellows, do not have to be attached to the base element, while still ensuring that there is a sealing function between the dispensing unit, especially the operating unit, and the base unit, especially a deck or deck portion of the base unit. Any leakage of liquid is thereby securely avoided.
  • said vent channel and/ or an outer vent opening and/ or an inner vent opening has or have a cross-section being smaller than the cross-section of the dispensing opening and/or than the cross-section of a dispensing channel, preferably being smaller by at least 50%, preferably by at least 70% or more preferably by at least 80%.
