Definitions

  • the invention relates to a container for metering liquid material, said container comprising an interior containing liquid material, a bottom with an endless, upright circumferential wall extending at least substantially in an axial direction of the container from said bottom, a sealing foil at the upper side of said upright circumferential wall, which retains the liquid material in the container, in which container an outlet can be created so as to place the container in an open condition, wherein the circumferential wall is deformable, at least in said open condition of the container, under the influence of an axial pressure force applied to the circumferential wall so as to reduce the volume of the interior of the container for the purpose of emptying the container at least partially in a metered manner via the outlet thus created.
  • Such a container is used as a portion pack, for example for containing a relatively small amount of a liquid material therein.
  • the term "relatively small amount” as used herein is understood to mean preferably an amount of a few millilitres to a few centilitres. Larger amounts are conceivable, however.
  • the term "liquid material” as used herein is understood to mean: viscous or non-viscous liquids or liquid-like materials, such as (condensed) milk, mayonnaise, ketchup, treacle, (chocolate) spread, glue and/or similar materials.
  • the liquid material may be a food or a non-food product or application, and it is also suitable for aseptic products and uses.
  • the metering of the contents takes place by axial compression of the container, the outlet being dimensioned so that on the one hand a certain counterpressure is provided, whilst on the other hand the liquid can be metered at an acceptable speed.
  • WO 2007/102730 A2 discloses a container in the form of a compressible tub.
  • the known container comprises a wall provided with a harmonica structure comprising deep notches that extend parallel to the upper edge.
  • an opening sealed with a foil is provided at the upper side of the tub.
  • the foil is removed from the opening in its entirety so as to release the opening.
  • the user can press an upper edge and the bottom together slightly, such that the contents of the tub exit the tub via the opening. It was found that the metering ability and ease of emptying the known container may be improved. In particular, it was found that a relatively high amount of liquid product may remain in the interior of the container after use, leading to undesired and unintended waste of the liquid product.
  • the container according to the invention comprises an upright circumferential wall.
  • the upright circumferential wall of the container consists of a total of four endless wall parts: A first endless wall part connected to the bottom, a second endless wall part above said first endless wall part and connected to that first endless wall part, a third endless wall part above said second endless wall part and connected to the second endless wall part, and a fourth endless wall part above said third endless wall part and connected to the third endless wall part.
  • the first endless wall part, the third endless wall part, and also the fourth endless wall part are conically shaped and taper outwards, as seen from the bottom to the upper side.
  • the second endless wall part extends from the first endless wall part to the third endless wall part, and substantially parallel to the axial direction of the container.
  • the second endless wall part and the third endless wall part join one another at the location of an endless fold line.
  • the third endless wall part and the fourth endless wall part join one another at the location of a further endless fold line.
  • These endless fold lines each define a plane extending substantially perpendicularly to the axial direction. Due to this arrangement, the second endless wall part and the third endless wall part are folded about the fold line under the influence of the axial pressure force, and the third endless wall part and the fourth endless wall part are simultaneously folded about the fold line under the influence of the same axial pressure force.
  • the use of only four endless wall parts according to the invention ensures that upon application of an axial force, a better controlled deformation of the cup is possible, since there the use of only four endless wall parts with only two folding lines restrict the degrees of freedom. This ensures a more predictable way of deformation of the container, and allows for a more controlled metering of the liquid in the container. Furthermore, the use of four wall parts, with only two fold lines, ensures that only a minimal part of the circumferential wall is deformed towards the interior of the container. Thus, a minimal contact surface is created to which liquid may stick, after deformation, ensuring a relatively high degree of emptying in the container according to the invention. The object of the present invention is thus accomplished.
  • An additional advantage of the container according to the present invention is that the second wall part and the third wall part are disposed so that they can be pressed substantially flat against each other, in which position the wall parts extend substantially parallel to the axial direction of the container.
  • the first wall part is rigidly connected to the bottom, such that upon deformation of the container, the relative position of the first wall part, with respect to the bottom, does not, or hardly change.
  • the first wall part, together with the bottom, thus forms a substantially rigid first arch-shaped element, which provides strength and stability to the container upon deformation.
  • the fourth wall part forms a substantially rigid arch-shaped element, which may be a second arch-shaped element in combination with the first arch-shaped element provided by the first wall part and the bottom.
  • the second and third wall part are present, which in this sense form deformation means that are deformable by exerting axial forces, which are directed to each other, on the first and second arch- shaped elements.
  • the second endless wall part and the third endless wall part join one another at the location of an endless fold line.
  • the third endless wall part and the fourth endless wall part join one another at the location of a further endless fold line.
  • the endless fold line and the further endless fold line each define a plane extending substantially perpendicularly to the axial direction.
  • the second endless wall part and the third endless wall part can be folded about the fold line under the influence of the axial pressure force, in which folding means that a relative pivoting movement between the second endless wall part and the third endless wall part takes place.
  • the third endless wall part and the fourth endless wall part can be folded about the fold line under the influence of the axial pressure force. Once again, this means that relative pivoting movement can take place between these wall parts.
  • the four endless wall parts, and the fold lines it is possible to construct he endless fold line and the further endless fold line such that they substantially maintain their radial position during folding.
  • some radial shift may occur, in particular some decreasing in the radial position may occur, but in the fully compressed state, the radial position of the fold line is substantially the same as the radial position of the fold line in the non- deformed state. This is advantageous, since it ensures that the liquid product in the container is not hindered by the fold lines and the wall parts during movement out of the container.
  • the third endless wall part is in a deformed state positioned such that it, as seen from the bottom to the upper side, substantially tapers inwards, or extends substantially parallel to the axial direction of the container.
  • the second endless wall part is in a deformed state at least partially positioned above the first endless wall part, and is substantially positioned radially inwards from the third endless wall part.
  • the first endless wall part is in a deformed state substantially positioned radially inwards from the fourth endless wall part.
  • deformed state herein, it is in particular meant a state wherein the container is deformed in a substantial maximal way. In this state, the endless wall parts of the container do not move, e.g. pivot, anymore upon further application of opposite axial forces on the container. With deformed state, it is thus meant a more or less fully compressed state of the container.
  • the first endless wall part, the second endless wall part and the third endless wall part each have a substantially equal height, as measured in the axial direction.
  • the height component in the axial direction is meant, in particular for the tapered wall parts, which also have a component in the radial direction.
  • the total wall-length is thus larger than the height measured in the axial direction.
  • a height, as measured in the axial direction, of the fourth endless wall part is larger than the height of the first endless wall part, the height of the second endless wall part, or the height of the third endless wall part.
  • the fourth endless wall part, situated near the top of the container has the largest height, as measured in the axial direction. This ensures that, in the deformed state, the interior space of the container near the top of the container remains substantially free of other endless wall parts, such that these wall parts do not form an obstruction for removal of liquid product from the container.
  • the container comprises a flanged edge joining the upper side of the fourth endless wall part, on which flanged edge the container is provided with the sealing foil.
  • the container is formed as defined in claim 10.
  • a recessed outflow channel is formed in the flange-like edge, which outflow channel is in communication with the interior of the container body at one end and which is closed at an opposite end.
  • the dimensions of the outflow channel, such as width and depth can be chosen in consideration to the viscosity of the filled product inside the container.
  • a weakened or broken zone may be provided in the flanged edge so as to make it possible to separate a separation part of the flanged edge located on the outer side of said weakened or broken zone from the container.
  • the flanged edge may have a protruding part, extending from a side of the flanged edge facing towards the bottom, which protruding part supports the fingertip during opening of the container. This protruding part makes it possible to open the pack with one hand only.
  • the sealing foil adheres to at least a part of the flanged edge, including the separation part thereof.
  • the sealing foil covers the outflow channel, which outflow channel is entirely provided on the side of the weakened or broken zone remote from the separation part.
  • the sealing foil has a release area that extends on the inner side of the weakened or broken zone, within which release area at least the closed end of the outflow channel is located. The release area is bounded by a boundary line located opposite the weakened or broken zone, which crosses the flow channel.
  • the sealing foil adheres to the flanged edge at the location of the release area, said bond being of the releasable type.
  • the releasable bond of the release area is at least partially adjacent to the weakened or broken zone.
  • the sealing foil is further connected to the flanged edge by a permanent bond at least at the location of the boundary line.
  • the releasable bond of the release area fully extends between the weakened or broken zone on the one hand, and the boundary line on the other hand.
  • the release area may thus substantially consist of a releasable bond.
  • the release area may, in an alternative embodiment, comprise a first strip of releasable bond surrounding the outflow channel.
  • the first strip may comprise smooth and gradual running edges. This ensures that the container may be opened easily, without tearing of the foil.

  • Suitable choice of process characteristics may include the use of different temperatures and/or pressures for the permanent bond and the releasable bond, respectively.
  • the weakened or broken zone is in an embodiment a broken zone, which may be established during fabrication of the container, for instance by means of a punching technique. By already providing a broken zone, the user will have to exert less force during opening of the container, and thus the chance of spilling is decreased.
  • the release area comprises a first strip of releasable bond surrounding the outflow channel and a second strip of releasable bond surrounding the first strip of releasable bond.
  • the first strip and the second strip of releasable bond are positioned such that in between the first and the second strip of releasable bond, a depressurize channel is formed which is arranged for, upon at least partially releasing the bond of the second strip, depressurizing the interior of the container. Due to the fact that the first strip of releasable bond is reached first during opening of the sealing foil, the depressurize channel is opened first, whilst the outflow channel is still closed due to the surrounding thereof of the second strip.
  • the depressurize channel is in gas-flowing contact with the interior of the container, such that the interior of the container can be depressurized, before opening the outflow channel.
  • the depressurize channel has relatively small dimensions compared to the outflow channel, and such small dimensions that outflow of liquid is prevented, but outflow of gas is possible. This prevents undesired and accidental outflow of liquid, as a result of external pressure exerted by a user on the container during opening.

When the bottom 3 and the flange-like edge 42 are moved together, the second wall part 20 and the fourth wall part 40 will push against the third wall part 30.

Abstract

La présente invention a trait à un récipient (1) pour mesurer une matière liquide. Le récipient comprend une partie intérieure qui contient une matière liquide, un fond (3) doté d'une paroi circonférentielle verticale sans fin (5) s'étendant au moins sensiblement dans une direction axiale du récipient à partir dudit fond, et une feuille assurant l'étanchéité(7) disposée sur le côté supérieur de ladite paroi circonférentielle verticale. Dans le récipient, une sortie (45) peut être créée de manière à placer le récipient dans un état ouvert. Ladite paroi circonférentielle est déformable, au moins à l'état ouvert du récipient, sous l'influence d'une force de pression axiale appliquée à la paroi circonférentielle de manière à réduire le volume de la partie intérieure du récipient en vue de vider le récipient au moins partiellement de manière mesurée par l'intermédiaire de la sortie ainsi créée. La paroi circonférentielle verticale du récipient est constituée d'un total de quatre parties de parois sans fin. Une première (10), une troisième (39) et une quatrième (40) partie de paroi sans fin sont de forme conique et s'effilent vers l'extérieur, tel que vu depuis le fond jusqu'au côté supérieur. Une deuxième partie de paroi sans fin (20), prévue entre la première et la troisième partie de paroi, s'étend sensiblement parallèlement à la direction axiale du récipient.
