Definitions

  • the present invention relates to a container for liquid contents and, more specifically, such a container comprising a compartment which is defined by flexible walls and whose volume depends on the relative position of the walls, and a duct means which forms a connection between said compartment and the surroundings .
  • a container of the type described by way of introduction is known from e.g. WO 9941155.
  • the container described therein is of a collapsible type and comprises three walls, viz. two opposite side walls and a bottom wall.
  • the walls which are made of a plastic material are flexible and interconnected to form a compartment whose volume depends on the relative position of the walls.
  • the container has a duct means which either may consist of a tubular piece introduced between the side walls or is formed integrally with the side walls.
  • the container is opened, for example, by cutting open the duct means, after which the liquid product held in the container can be poured.
  • This durable resealability is achieved with the aid of openable and closable connecting means, such as a screw cap, which are connected to the duct means, or with the aid of pinching means applied over the duct means .
  • These methods of providing durable resealability of a container are complicated. There is thus a need for a container which allows easier durable resealing.
  • a first object of the present invention thus is to provide an improved container of the type described by way of introduction. Another object is to provide such a container allowing improved durable resealability.
  • a container for liquid contents comprising a compartment which is defined by flexible walls and whose volume depends on the relative position of the walls, a flexible duct means which forms a connection - between said compartment and the surroundings, the duct means being bringable to an open state and to a closed state, and the compartment having a bottom region, in which the liquid contents are essentially collected as the container assumes an upright position, said container being characterised in that said walls, by being actuated by said contents when collected in said bottom region, are adapted to assume a relative position acting for an increase in volume of the compartment, which increase in volume is counteracted by a negative pressure generated in the compartment, said duct means is adapted to be brought to said closed state in response to the negative pressure generated in the compartment, and said duct means is extended from the compartment at an angle to a longitudinal axis of the container.
  • the container comprises walls which, by being actuated by the liquid contents, may assume different positions affecting the volume of the compartment. It will be ensured that the walls assume a position acting for an increase in volume of the compartment as the container assumes an upright position. Thus a negative pressure is generated in the compartment, said negative pressure counteracting the increase in volume and besides causing the duct means to be closed.
  • the extent of the duct means from the compartment at an angle to a longitudinal axis of the container prevents the pressure which the contents exert on the side walls of the container from propagating to the duct means .
  • the duct means will thus be closed when a pouring motion is terminated and the container is made to assume its upright position once more.
  • the need for mechanical durable sealing measures in the form of e.g. screw caps or clips is eliminated.
  • the inventive container comprises two opposite side walls which are joined along a common connecting portion and which in a non-actuated state strive to abut flush with each other.
  • the duct means is formed integrally with said side walls and is advantageously formed of two projecting wall portions, abutting flush with each other, of the side walls, said wall portions being joined with each other along their edges .
  • the duct means has inner surfaces which face each other and are made to abut each other in a sealing manner when the duct means is closed in response to the negative pressure generated in the com- partment . Said surfaces advantageously have a high degree of flatness, which contributes to ensuring an air-tight durable seal of the duct means in response to a negative pressure generated in the compartment .
  • the container is preferably made of a material containing a filler of mineral material and a binder of polyolefin material .
  • the filler is advantageously chalk (calcium carbonate) .
  • a carrying means is arranged on a first side of the container.
  • the carrying means is advan- tageously arranged in said connecting portion.
  • the duct means is arranged in an outlet area located on a second side of the container and at a distance from said bottom region. Said second side is advantageously opposite to said first side.
  • the duct means extends perpendicular to a longitudinal axis of the container.
  • the duct means is preferably sealed in an unopened state of the container and is openable by cutting or like operation.
  • Figs la and lb are perspective views of a preferred embodiment of an inventive container in a filled and non- opened state .
  • Fig. 2 is a top plan view of the container shown in
  • Figs 3a and 3b are perspective views of the container shown in Figs la and lb in a filled and opened state.
  • Fig. 4 is a cross-sectional view along line A-A in Fig. 3a.
  • Fig. 5 is a perspective view of the container shown in Figs 3a and 3b during a pouring motion.
  • Fig. 6 is a cross-sectional view along line B-B in Fig. 5.
  • Figs 7a-7c are perspective views showing the handling of the container shown in Figs 3a and 3b for pouring some of the contents held in the container.
  • Fig. 8 is a top plan view of a second embodiment of an inventive container with a duct means extended from the compartment at an acute angle to a longitudinal axis of the container.
  • Figs la and lb illustrate a preferred embodiment of an inventive container 1 in an unopened state and filled with liquid contents.
  • the container 1 is particularly suitable for liquid food products such as milk, fruit juice, water or wine .
  • the container 1 is of a collapsible type, i.e. compressible or foldable, and comprises to this end three flexible walls, two of which are opposite side walls 2 and one is a bottom wall 3.
  • the walls 2, 3 can be made of a plastic material or preferably of a material containing a filler of mineral material and a binder of polyolefin material .
  • the filler is advantageously chalk.
  • the walls 2, 3 are further interconnected to form a compartment 4 whose volume depends on the relative position of the walls 2, 3 and which is clearly shown in Fig. 2.
  • the two side walls 2 are joined by welding along a connecting portion 5.
  • the flexible walls 2, 3 are formed in such manner and have such rigidity that said side walls 2 in a non- actuated state, which corresponds to the empty state of the container 1, strive to abut flush with each other. If the walls contain a mineral-based filler, such as chalk, said rigidity is essentially obtained by means of the filler.
  • the inventive container 1 When the inventive container 1 is filled with liquid contents, the contents will actuate the walls 2, 3 to such a degree that they assume a relative position in which the compartment 4 defines a volume that is necessary to hold the contents.
  • the container 1 is, as mentioned above, of a collapsing type, which means that the volume defined by the compartment 4 decreases as the container 1 is emptied of its contents.
  • a carrying means 6 is arranged in the connecting portion 5 at a first side of the container 1 and comprises in the shown embodiment an opening area 8 with a first, essentially round opening 9 and a second, essentially elongate opening 10.
  • the carrying means 6 forms a handle 11 which makes it possible for a user to lift the container 1 using four fingers, while at the same time a load-absorbing portion 12 is formed between the openings 9, 10, preventing the handle 11 from being folded or deformed in some other way in the handl- ing of the container 1.
  • Fig. 2 is a top plan view of the container 1 illustrated in Figs la and lb, the nearest side wall 2 being removed. Now it is possible to see the inside of a rear side wall 2, a bottom wall 3 and the design of the connecting portion 5, along which the two side walls 2 are connected with each other.
  • the side walls 2 are connected with the bottom wall 3, on the one hand via a lower connecting portion 14 along which each side wall 2 is connected with the bottom wall 3 and, on the other hand, via two lateral connecting portions 5 along which all three walls 2, 3 are connected with each other in a common welded joint.
  • the compartment 4 of the container 1 is thus defined by the side walls 2 and the bottom wall 3.
  • the connecting portion 5 forms boundary lines 16 facing the compartment 4.
  • the compartment 4 comprises a bottom area 13 as men- tioned above, a central area 17 in which boundary lines 16, facing the compartment 4, of the connecting portions 5 are parallel, and an upper arched area 18, in which the boundary lines 16 extend essentially arcuately towards each other, however, not in an outlet area 19 at a second side 20 of the container 1, which outlet area 19 will be described in more detail below.
  • This design makes it possible for the container 1 to stand in a stable manner independently of the extent to which it is filled.
  • the inventive container 1 also has a duct means 22, which is arranged at a distance from the bottom region 21 in said outlet area 19.
  • the duct means 22 is arranged on the second side 20 of the container 1, which is opposite to said first side 7, on which the carrying means 6 is arranged.
  • the duct means 22 is formed integrally with the side walls 2. More specifically, the duct means 22 is formed of a wall portion 23 of each side wall 2. Each wall portion 23 extends at an angle to a longitudinal axis of the container and thus forms a laterally extending projection of each side wall 2, and the wall portions 23 are connected with each other along their lateral edges, which are thus included in said connecting portion 5.
  • the interconnected wall portions 23 thus forms said duct means 22 which at a first end 24 communicates with the compartments 4 of the container 1 and at a second end 25 is sealed by said connecting portion 5. Since said wall portions, and thus also the duct means, extend from the compartment 4 at an angle to a longitudinal axis of the container 1, it is ensured that the pressure caused by the liquid contents and acting on the walls of the container is not propagated to the duct means.
  • the duct means has an essentially perpendicular extent to said longitudinal axis.
  • the duct means 22 consists of two wall portions 23, which are sealed along their edges and which are flexible and each have an inner surface 26, which inner surfaces in a state without actuation by said contents abut flush with each other.
  • the second end 25 of the duct means 22 is removed by cutting or like operation. Of course, such cutting can be made to form an opening with an optional angle. A thus opened container 1 is illustrated in Figs 3a and 3b.
  • Fig. 4 is a cross-sectional view of the container 1 shown in Fig. 3a.
  • Fig. 4 is a cross-sectional view of the container 1 shown in Fig. 3a.
  • Fig. 5 shows an inventive container 1 which is subjected to a pouring motion
  • Fig. 6 is a cross- sectional view of the container 1 illustrated in Fig. 5. The container 1 is moved from an upright position to a forwardly inclined position
  • Fig. 6 is a cross- sectional view of the container 1 illustrated in Fig. 5.
  • FIG. 6 shows how some of the contents has been brought to the arched area 18 of the compartment 4, whereby the resulting increase in volume in this area 18 is to some extent compensated for by a decrease in volume in the bottom region 21.
  • the relative change in volume is adjusted in such manner that the negative pressure prevailing in the compartment 4 ceases .
  • Figs 7a-7c illustrate how the above-described inventive container 1 is handled for pouring liquid contents, such as milk, held in the container 1.
  • Fig. 7a illustrates the opened container 1 in an upright position on a base. The liquid contents are collected in said bottom region 21.
  • Fig. 7b shows the container 1 in a lifted state while performing a pouring motion, whereby some of the contents held in the container 1 is brought from the bottom region 21 to the arched region 18 and the associated outlet area 19.
  • the liquid contents will be passed to the duct means 22 and thereby exert a pressure which makes the wall portions 23 of the duct means 22 and their inner surfaces 26 separate to allow pouring some of the contents into a glass 27.
  • the pressure exerted by said contents on the side walls 2 in the bottom region 21 will decrease, thus making the side walls strive to be moved towards each other, resulting in a decrease in volume of the compartment 4.
  • This decrease in volume is relatively greater than the increase in volume taking place in said arched area 18, which results in the negative pressure prevailing in the compartment ceasing.
  • the inventive container 1 is thus durably self- sealing, which means that the need for mechanical durable sealing measures, such as sealing by means of a cap or clip, is eliminated.
  • mechanical durable sealing measures such as sealing by means of a cap or clip
  • the present invention thus concerns a durably self- sealing container 1.
  • the container 1 comprises a duct means 22 which is openable for example, by cutting.
  • the container 1 has flexible walls 2, 3, which during handling of the container 1 are actuated by liquid contents held in the container 1, in such manner that the volume of a compartment 4 defined by the walls 2, 3 decreases when performing a pouring motion and increases when bringing the container 1 to an upright position. Said increase in volume results in generation of a negative pressure in the compartment 4, which negative pressure counteracts the increase in volume and ensures that the open duct means 22 is sealed.
  • Fig. 8 shows another embodiment of a container 1 according to the present invention with a duct means 22 extended from the compartment 4 at an angle of less than 90° to a longitudinal axis of the container 1.
  • the present invention is not restricted to the shown embodiment of the inventive container 1; for instance, the duct means can be integrated in the container 1, i.e. it does not have to project from the container 1 but only from the compartment 4.
  • the duct means can be integrated in the container 1, i.e. it does not have to project from the container 1 but only from the compartment 4.
