Definitions

  • the present invention relates to the field of spouted containers, e.g. spouted pouches.
  • the pouch also has a unitary plastic cap unit that includes a cap body, a base portion, and an integrated strap.
  • the base portion is integrally formed to the lower edge of the skirt of the cap body via one or more breakable bridges.
  • the base portion is configured to remain connected to the spout upon removal of the cap body from the neck by the user.
  • the cap is a snap-on type cap and the cap body comprises a pair of wing-shaped handles that extend diametrically opposite from a central cap body portion.
  • Each handle has, seen in side view thereon, an outer periphery with a bottom side, a top side, and a tip remote from the skirt.
  • the strap is integral at a first end thereof to the annular base portion and at a second end thereof to one of the wing-shaped handles and is adapted to remain connected to both the base portion, and thus to the spout, and to the respective wing-shaped handle upon removal of the cap body from the neck of the article by the user.
  • the provision of the strap seeks to avoid that the cap body becomes separated from the pouch, e.g. reducing the chance that the cap body ends up in the environment instead of being properly disposed of, e.g. in view of recycling.
  • the length of the strap is between 30 and 50 millimetres, e.g. sufficient to allow moving the cap body over the top end or mouth end of the neck for removal and replacement of the cap body. This length also allows to keep the cap body a fair distance away from the neck, which facilitates drinking directly from the pouch as the user puts the neck between his/her lips.
  • the cap unit has a cap body, a base portion, and an integrated strap.
  • the cap is screw cap that is screwed onto the neck of the spout.
  • the base portion is embodied as a ring that is freely rotatable about the neck allowing the ring to follow the cap body during screw motion thereof.
  • the strap connects the base portion to the lower region of the skirt of the central cap body portion.
  • the cap body further has a gripping paddle portion, that is embodied as a flat panel in the vertical plane through the main axis.
  • the present invention aims to provide a spouted pouch with further enhanced comfort for the user, in particular in view of dispensing, more in particular in view of drinking directly from the pouch as the user puts the neck between his/her lips.
  • a spouted container according to claim 1 is provided.
  • the spouted container is, in practical embodiments, generally composed of a container body, a spout, and a cap unit.
  • the container body is filled or is to be filled with a product to be dispensed, e.g. with a liquid food product, e.g. a beverage, a fruit product, a diary (e.g. yogurt) product, or other product for human consumption.
  • a product to be dispensed e.g. with a liquid food product, e.g. a beverage, a fruit product, a diary (e.g. yogurt) product, or other product for human consumption.
  • Other products can be filled into the container body as well, e.g. detergents, oil products, liquid cosmetics, powdery products, etc. Whilst this includes products that are not suited for drinking directly from the container, the inventive solution affords a reduced risk of spillage as the cap body does not infer with pouring the product from the container.
  • the spout has a spout body made, e.g. moulded, e.g. injection molded, of plastic material, which spout body has an attachment portion that is attached to the container body and has a tubular neck extending upward along a main axis thereof from the attachment portion, which neck delimits a section of a product passage that extends through the spout body to a mouth at the top end of the neck.
  • a spout body made, e.g. moulded, e.g. injection molded, of plastic material, which spout body has an attachment portion that is attached to the container body and has a tubular neck extending upward along a main axis thereof from the attachment portion, which neck delimits a section of a product passage that extends through the spout body to a mouth at the top end of the neck.
  • the cap unit is made, e.g. moulded, e.g. injection moulded, as one piece of plastic material that is distinct from the spout.
  • the cap unit comprises a cap body and an integrated base portion, wherein the cap body comprises a central cap body portion with a top wall structure and a downward depending skirt having an interior side, an exterior side, and a lower edge remote from the top wall structure, wherein the base portion is integrally connected to the skirt via one or more breakable bridges.

  • the base portion and the spout body have cooperating permanent snap-fit joint portions which fix the base portion on the spout body both in axial direction and in circumferential direction relative to the neck and which keep the base portion fixed to the spout body upon removal of the central cap from the neck by a user for dispensing of product from the container via the product passage.
  • the cap unit further comprises a cantilever arm portion having an inner end that is integral with the base portion, which cantilever arm portion extends laterally away to an outer end thereof that is laterally outward of the skirt of the central cap body portion in a closed position of the cap body.
  • the cantilever arm has a fixed orientation relative to the spout, e.g. in contrast to the freely rotatable ring base portion of WO2021/214596.
  • the cap unit further comprises a lateral cap body portion that adjoins the central cap body portion and extends laterally away from the central cap body portion towards the outer end of the cantilever arm portion.
  • the outer end of the cantilever arm portion and the lateral cap body portion are joined via a hinge portion of the cap unit which defines a hinge axis perpendicular to the lateral extension of the cantilever arm portion and of the lateral cap body portion.
  • Cooperating snap connector formations are provided which are configured to provide for a snap-on functionality for the central cap body portion relative to the neck. This snap-on functionality allows for the cap body to be replaced and then retained on the spout so that the container is closed again.
  • the cap unit is configured such that, for removal of the cap body from the neck by the user from the closed position, the cap body is lifted from the neck through pivoting thereof about the hinge axis of the hinge portion into a dispensing position allowing dispensing of product from the container via the product passage.

  • the inventive design retains the cap body, in particular the central cap body portion thereof, at a location that is further remote from the neck of the spout.
  • This allows to enhance user comfort as the cap body, in particular the central cap body portion thereof, may now be properly spaced away from the face of the person drinking from the neck of the spout, e.g. to the left or to the right of the mouth of the person.
  • the cap body is in a locked condition when at the dispensing position, so that the cap body effectively remains in place relative to the container. This, e.g. avoids, undesirable motion of the cap body during drinking from the container, e.g. with the effect that the cap body is or may be in motion, e.g. (repeatedly) touches the face of the person drinking from the container.
  • the cap body is upside-down in the dispensing position, so with the top wall structure of the cap body directed towards, e.g. closely adjacent, the container.
  • the top wall structure of the cap body is adjacent a top edge of a spouted pouch.
  • the central cap body portion and the neck of the spout have cooperating sealing surfaces that close the product passage in the closed position of the cap body.
  • the angle may correspond to the cap body being in close proximity or against a top edge of the pouch.
  • the angle over which the cap body is swung from the closed position to the dispensing position about the hinge axis may be between 120 and 210 degrees from the closed position, e.g. between 150 - 180 degrees.
  • the lateral cap body portion in the dispensing position, forms an outwardly directed extension of the cantilever arm.
  • the user can simply take hold of the cap body and fold it back about the hinge portion to the neck so as the place the central cap body portion over the neck.
  • the one or more locking formations herein disengage, preferably automatically disengage without further action of the user being required.
  • the replacing of the cap body causes the snap formations to retain the cap body in closed position by snap-fit action.
  • the container is pouch having a flexible material pouch body, which pouch has a top edge, wherein the attachment portion of the spout is sealed in a top edge seal of the pouch, e.g. between two pouch walls, and wherein the cantilever arm extends along the top edge of the pouch.
  • This arrangement is advantageous for drinking directly from the pouch as the cap body is effectively cleared from the neck in the dispensing position of the cap body.
  • the lateral extension of the cantilever arm portion is, seen in view from above, in embodiments aligned with the top edge of the pouch.
  • the cantilever arm can be at an angle, seen in view from above, relative to the top edge of the pouch, e.g. the angle being at most 25 degrees.
  • the cap unit is configured such that in the dispensing position, for embodiments wherein the neck has an outer diameter between 6 and 15 mm, the central cap body portion is laterally spaced at least 25 mm, preferably at least 35 mm, from the outer surface of the neck.
  • the outer end of the cantilever arm portion is located at least one time the outer diameter of the neck away from the outer surface of the neck.
  • the outer end of the cantilever arm portion is about twice the diameter of the neck away from the neck.
  • the outer end of the cantilever arm portion is located at least 10 mm away from the skirt of the central cap body portion., e.g. for embodiments wherein the neck has an outer diameter between 6 and 15 mm, e.g. at least 15 mm away.
  • the cap unit is configured such that in the dispensing position the lower edge of the skirt of the central cap body portion is located below an imaginary plane of the mouth, perpendicular to the main axis of the neck.
  • the cantilever arm extends in direction of the top edge of a spouted pouch, this may mean that the top of the central cap body portion is directed downwards and is in close proximity to, or even contact with, the top edge of the spouted pouch.
  • the lateral cap body portion has a downward projecting tab at the underside thereof, which adjoins the hinge portion.
  • the cap body further comprises a lifting portion that adjoins the central cap body portion and, preferably, extends laterally away from the central cap body portion diametrically opposite the lateral cap body portion.
  • neither the lateral cap body portion nor the lifting portion, when present, extend above the top wall of the cap body, seen with the cap body in closed position.
  • This allows for an optimized operational angle of the hinge, in particular when the cantilever arm extends in direction of the top edge of a spouted pouch.
  • This may mean that the top of the central cap body portion is directed downwards and is in close proximity to, or even contact with, the top edge of the spouted pouch.
  • the central cap body portion in the dispensing position, is spaced further from the neck than a vertical side edge of the container, e.g. of the pouch.
  • the lifting portion is embodied as a lifting tab that is configured to be engaged from below by a finger of the user, e.g. the tab extending at least 10 mm outwards from the skirt of the central cap body portion, e.g. between 20 and 35 mm, e.g. for a spout having an outer diameter of the neck between 8 and 15 mm.
  • the lifting tab extends from a top region of the skirt of the cap body, e.g. with the lateral cap body portion also extending from said top region yet at the diametrically opposite side of the skirt.
  • a vertical spacing of at least 10 mm is present between the container, e.g. the top edge of the pouch, and the lifting portion. This facilitates the placing of a finger underneath the lifting portion for opening the pouch.

  • the locking formations are embodied as resilient formations that allow the one formation to flex and pass the other formation when moving the cap body to the dispensing position. The one locking formation, or both formations, then spring back so as to provide the locking action.
  • locking is caused by frictional engagement between the first and second locking formations.
  • the first locking formation is arranged at an underside of the cantilever arm portion.
  • the first locking formation is within the contour of the cantilever arm and does not extend outward thereof. This, e.g., avoids damage to the (rather small) first locking formation.
  • the second locking formation is arranged at an underside of the lateral cap body portion when the central cap body is in closed position.
  • the second locking formation is within the contour of the lateral cap body portion and does not extend outward thereof. This, e.g., avoids damage to the (rather small) second locking formation.
  • the first locking formation is arranged at an underside of the cantilever arm portion and the second locking formation is arranged at an underside of the lateral cap body portion when the central cap body is in closed position.
  • the lateral cap body portion is configured such that, in closed position, the second locking formation is located further laterally outward than the hinge axis. When moving the cap body towards the dispensing position around the hinge axis, the second locking formation travels to locking engagement with the first locking formation.
  • the cantilever arm portion has a width of at least 4 mm, e.g. between 5 and 8 mm, e.g. with an outer diameter of the neck of between 6 and 15 mm.
  • the cantilever arm portion has a greatest width at its inner end, tapering to a smallest width at its outer end.
  • the cantilever arm portion is formed by an upper broad strip having a thickness of at most 1.5 mm, a width of at least 4 mm, combined with one or more reinforcement ribs extending along the length of the cantilever arm portion, e.g. a single reinforcement rib extending centrally at the underside of the upper broad strip.
