Definitions

  • the present invention relates to a freezing mould bag, especially for freezing ice lumps or ice cubes, and more precisely a freezing mould bag providing a self-closing effect, and comprising:
  • Numerous freezing mould bags are known within the art, e.g. from US Patent No. 3,207,420, Re-issued US Patent No. 31,890, US Patent No. 4,822,180, corresponding to European Patent No. 0 264 407, European Patent Application No. 0 129 072, International Patent Application, Publication No. WO82/00279, International Patent Application, Publication No. WO87/01183, and International Patent Application, Publication No. WO86/04561.
  • European Patent No. 0 264 407 also discloses a freezing mould bag of the above described type which bag according to the specification of the European Patent is adapted to provide a self-closing function.
  • the freezing mould bag according to the European Patent No. 0 264 407 comprises two closure flaps defining closure pockets of the freezing mould bag and is stated to seal the interior of the freezing mould bag and to prevent that liquid or water leaks from the interior of the freezing mould bag, provided the interior of the freezing mould bag is filled with liquid, preferably water, intended to be frozen to ice lumps or ice cubes.
  • a particular safe self-closing funtion is stated to be obtained through the provision of the closure pockets extending in the entire length of, but not more than, the length of the inlet channel and through the provision of a set of double weld seams defining the constriction.
  • the complete filling of the closure pockets of the freezing mould bag further results in that the closure flaps of the freezing mould bag are pressed against one another in consequence of tensioning of the foils of the freezing mould bag, which tensioning is established in specific weld seams providing a constriction of an inlet channel of the freezing mould bag, which inlet channel is of a configuration basically tapering from an inlet opening of the freezing mould bag towards the interior of the freezing mould bag.
  • the complete filling of the interior of the freezing mould bag is consequently based on a completely evacuated state of the interior of the freezing mould bag prior to the filling of the interior of the freezing mould bag and a complete filling of the interior of the freezing mould bag, and specifically a complete filling of the closure pockets of the freezing mould bag.
  • European Patent Application No. 0 129 072 further describes a freezing mould bag which according to the specification of the European Patent Application is adapted to generate a far more elaborated self-closing function as compared to the function of the freezing mould bag according to the above-mentioned European Patent No. 0 264 407.
  • a self-closing function is established even though the closure pockets are not completely filled with liquid or water, as the freezing mould bag according to the above-mentioned European Patent Application No. 0 129 072 is stated to be adapted to provide a self-closing function independent of a complete or partial filling out of the interior of the freezing mould bag with liquid or water.
  • the self-closing function of the freezing mould bag is stated to be provided by means of a narrow, tubular inlet arranged within an inlet channel of the freezing mould bag and extending from the interior of the freezing mould bag through the inlet channel to a position approximately half-way along the inlet channel along the longitudinal direction of the inlet channel, in which position the tubular inlet is connected to two sheets of the freezing mould bag defining two closure pockets.
  • the freezing mould bag according to the above-mentioned European Patent Application No. 0 129 072 has proven not to function absolutely satisfactorily as the freezing mould bag does not provide a safe and reliable self-closing function, i.e. the freezing mould bag does not guarantee that there is every probability that the freezing mould bag is closing as the freezing mould bag is turned upside down for generating a self-closing function after a complete or partial filling of the interior of the freezing mould bag with liquid or water.
  • This lack of reliability is believed to be based on the following relations.
  • the closure pockets are, on the one hand, in consequence of the small size of the closure pockets unable to generate a pressure capable of closing the inlet channel of the freezing mould bag.
  • the structure of the freezing mould bag according to the above-mentioned European Patent Application No. 0 129 072 is, on the other hand, not deduced, taking into due consideration the hydrodynamic and hydraulic relations which, as will be explained below with reference to the detailed discussion of the realization on which the present invention is based, may be utilized for creating a safe and reliable self-closing function, i.e. a self-closing function which, as the self-closing mould bag is completely or partially filled with liquid or water, and as the freezing mould bag is turned upside down, provides a substantially fail-safe closing of the interior of the freezing mould bag independent of whether or not the closure pockets are filled with liquid or air at the time the self-closing freezing mould bag is turned upside down.
  • a self-closing function which, as the self-closing mould bag is completely or partially filled with liquid or water, and as the freezing mould bag is turned upside down, provides a substantially fail-safe closing of the interior of the freezing mould bag independent of whether or not the closure pockets are filled with liquid or
  • An object of the present invention is to provide a freezing mould bag which in a safe and reliable manner is capable of generating a self-closing effect as the freezing mould bag is turned upside down, i.e. turned from a position in which an inlet opening of the freezing mould bag is facing upwardly to a position in which the inlet opening is facing downwardly, independent of whether or not the interior of the freezing mould bag is filled completely or partially with liquid or water so as to guarantee that the liquid or water contained within the interior of the freezing mould bag is confined within the interior of the freezing mould bag and so as to limit the amount of liquid or water which is spilt from the freezing mould bag as the freezing mould bag after filling is turned upside down to substantially no more than an amount of liquid or water confined within a section or segment of an inlet channel of the freezing mould bag and to prevent that liquid or water not confined within the interior of the freezing mould bag is spilt.
  • a freezing mould bag of the kind defined above being characterized in that the closure valve flaps extend from the inlet opening beyond the constriction at the transition between the first and the second segment of the inlet channel to a position between the constriction and the centre of the second segment, and that the second segment has a maximum dimension along the second direction of at least 2 times the dimension of the constriction along the second direction.
  • the present invention is based on the following realization.
  • the length of the valve closure flaps is, as will be readily understood by a person having ordinary skill in the art, of importance, firstly as to the amount of liquid or water which is spilt as the freezing mould bag is turned upside down after the filling of the interior of the freezing mould bag with liquid or water, as a part of the amount liquid or water from the interior of the freezing mould bag into the closure pockets.
  • closure valve flaps implemented in accordance with the freezing mould bag according to the present invention fulfil the requirements as to, on the one hand, the spilling of a minimum amount of water or liquid and, on the other hand, a swift and efficient filling of the closure pockets.
  • the closure valve flaps of the freezing mould bag according to the present invention may be constituted by separate flap components which may be made from the same material as the sheets of the freezing mould bag or a different material of increased or reduced flexibility.
  • the closure valve flaps are constituted by turned-in parts of the sheets.
  • the closure valve flaps are consequently constituted by integral components or parts of the sheets of the freezing mould bag.
  • the closure valve flaps may be fastened to the sheets through joints which may be established through glueing or welding, dependent on the specific materials of the sheets and the closure valve flaps of the freezing mould bag.
  • the closure valve flaps preferably extend to a position defining a distance from the constriction at the transition between the first and the second segment of the inlet channel being at least 0.5 times the dimension of the constriction along the second direction, i.e. along the direction perpendicular to the longitudinal direction of the inlet channel, preferably 0.5-2 times the dimension of the constriction.
  • the second segment has a maximum dimension along the second direction of at least two times the dimension of the constriction along the second direction.
  • the second segment of the inlet channel has a maximum dimension along the second direction of the inlet channel being 2-7 times the dimension of the constriction, further preferably 2.4-5 times the dimension of the constriction, such as 2.6-3.4 times the dimension of the constriction.
  • the first segment of the inlet channel has a dimension, along the second direction of the inlet channel, i.e. perpendicular to the longitudinal direction of the inlet channel, at the inlet opening being approximately two times the dimension of the constriction along the second direction.
  • the first segment of the inlet channel tapering from the inlet opening towards the interior of the freezing mould bag may be bounded by joints of any appropriate configuration.
  • the first segment of the inlet channel may, consequently, be bounded by joints constituting straight lines or curved lines defining a first segment of a convex or concave configuration.
  • the joints defining the first segment are preferably constituted by straight lines or curved lines defining a first segment of a basically concave configuration.
  • the second segment of the inlet channel may be bounded by joints of any appropriate configuration.
  • the second segment of the inlet channel may, consequently, be bounded by joints constituting straight lines or curved lines, however, preferably constituting partly straight lines and partly curved lines, such as segments of circles defining a second segment of a convex or concave configuration, preferably a second segment of a concave configuration.
  • the inlet channel comprising the first and the second segment may, fulfilling the above described requirements, be of an unsymmetrical configuration and further be of an overall curved configuration.
  • the inlet channel is substantially symmetrical relative to its longitudinal axis.
  • the freezing mould bag comprises a plurality of mould compartments, preferably more than two mould compartments, further preferably more than twelve mould compartments, such as eighteen or twenty-four mould compartments.
  • the second segment of the inlet channel has a size corresponding to approximately 1-2 times a single mould compartment, preferably 2 times a single mould compartment.
  • the configuration of the second segment having dimensions so as to provide the second segment having a size larger than the size of a single mould compartment further serves the purpose of informing the consumer that the second segment is different from mould compartments in which ice lumps or ice cubes are contained, as the ice lump or ice cube which is made from the liquid or water confined within the second segment of the inlet channel contains segments of the closure valve flaps frozen within the liquid or water, which segments are later on liberated, as the ice lump or ice cube is thawed.
  • the sheets of foil material from which the freezing mould bag is composed or made, and from which the closure valve flaps in accordance with the presently preferred embodiment of the freezing mould bag according to the present invention are made from turned-in parts of the sheets, are preferably manufactured by cutting segments of continuous paths of foil material as will be well-known within the art.
  • the sheets of foil material may further constitute segments of planar foil paths or segments of foil paths provided with printings corresponding to the mould compartments of the freezing mould bag.
  • one of the continuous foil paths is or are brought into contact with one or more printing tools, such as a punching tool or a heat-printing tool, e.g.
  • a heated printing dye for generating the above-mentioned printings corresponding to the mould compartments of the freezing mould bag.
  • the generation of printings of the sheets of the freezing mould bag or of one of the sheets of the freezing mould bag, in case the freezing mould bag is not of a symmetrical configuration, may serve the purpose of allowing an increased filling of the interior of the freezing mould bag and consequently provide larger ice lumps or ice cubes within the same dimensions of the freezing mould bag as compared to a freezing mould bag, the sheets of which are not provided with printings corresponding to the mould compartments of the freezing mould bag.
  • the sheets from which the freezing mould bag is produced may be constituted by plastic foil sheets or aluminum foil sheets, and the joints may be constituted by welded joints or glue joints.
  • the sheets may further be constituted by laminates of e.g. plastics material and metal foil or plastic foils to which a metal coating is applied in an evaporation process.
  • the choice of foil material and the choice of the thickness of the foil material or foil materials firstly depends on the consideration regarding, on the one hand, the provision of a hermetically sealed freezing mould bag, i.e. a freezing mould bag which does not leak unintentionally and, on the other hand, the provision of a freezing mould bag which after the operation of freezing the liquid or water to e.g. ice lumps or ice cubes is easily openable by cutting or tearing the sheets apart, and secondly depends on the provision of an efficient self-closing effect.
  • a first, presently preferred embodiment of a freezing mould bag according to the present invention is shown in a plane and schematical view.
  • the freezing mould bag is in its entirety designated the reference numeral 10.
  • the freezing mould bag 10 is, as will be evident from the perspective and sectional views of Figs. 2 and 3, illustrating the interior of the freezing mould bag composed of two identical plastic sheets, preferably sheets of LD polyethylene foil of a thickness of 25 ⁇ m, or alternatively HD polyethylene foil of a thickness of 18 ⁇ m, the sheets being designated the reference numerals 12 and 14.

  • the sheets 12 and 14 are of a substantially rectangular configuration and are arranged in an overlapping juxtaposed relationship in which the above-mentioned turned-in parts 16 and 18 extend into the interior of the freezing mould bag 10, as the sheets 12 and 14 are joined together through partly a peripheral joint 20 extending along the periphery of the sheets 12 and 14, except for an area to be described below, and partly octagonal, discretely arranged joints 22 which together, and together with the peripheral joint 20, define a total of 24 individual mould compartments, one of which is designated the reference numeral 24.
  • the circumferential joint 20 is interrupted as the sheets 12 and 14 are not joined together at this area so as to provide an inlet opening at said area, which inlet opening constitutes an inlet opening of an inlet channel extending from the environment to the interior of the freezing mould bag 10.
  • Said area defining the inlet opening of the inlet channel is designated the reference numeral 26.
  • the mutually convergent joints 28 define a first segment of the inlet channel of the freezing mould bag 10 beyond which first segment mutually divergent joints 32 define a second segment of the inlet channel, which second segment has dimensions in a direction perpendicular to the inlet direction or the longitudinal direction of the inlet channel far larger than the corresponding dimensions of the first segment of the inlet channel.
  • the above-mentioned circular reinforcing joints 30 define a constriction at the conjunction or the transition between the first and the second segment of the inlet channel, which constriction serves a specific purpose in accordance with the teachings of the present invention, as will be described in greater detail below.
  • the two sheets 12 and 14 of the freezing mould bag are arranged in a substantial planar juxtaposed position as the interior of the freezing mould bag may be partially filled with air defining air pockets within the interior of the freezing mould bag.

  • liquid preferably or specifically water to be frozen to ice lumps or ice cubes
  • the liquid or water fills out the mould compartments 24 which are distended by the water pressure and further fills out the second segment of the inlet channel.
  • the sheets 12 and 14 are distended relative to one another by which distension the turned-in parts 16 and 18 of the sheets 12 and 14 are separated from one another resulting in a separation of the lower edges 17 and 19 of the turned-in parts 16 and 18, respectively, of the sheets 12 and 14.
  • the liquid or water filling out the interior of the freezing mould bag 10 rises within the interior of the freezing mould bag on both sides of the turned-in parts 16 and 18 of the sheets 12 and 14, respectively, as the liquid or water rises within the cavities constituting closure pockets defined between the turned-in parts 16 and 18 of the sheets 12 and 14 and the sheets 12 and 14, respectively, to a specific height determined by the amount of air confined within the cavities or closure pockets.

  • the closing or sealing of the interior of the freezing mould bag 10 is not established at the time at which the liquid or water has been filled into the interior of the freezing mould bag 10 as the air pockets above the liquid or water surfaces 34 and 36 within the closure pockets defined between the sheets 12 and 14 and the corresponding turned-in parts 16 and 18, respectively, thereof, and the presence of liquid or water between the turned-in parts 16 and 18 of the foils 12 and 14, respectively, precludes the generation of a water pressure within the cavities, which water pressure is capable of pressing the closure valve flaps generated by the turned-in parts 16 and 18 against one another.
  • the turned-in parts 16 and 18 of the sheets 12 and 14 are caused to collapse and consequently pressed against one another so as to close the inlet channel defined between the turned-in parts 16 and 18 of the sheets 12 and 14 at the constriction, whereupon the liquid or water flowing from the interior of the freezing mould bag 10, more precisely flowing from the second segment of the inlet channel, flows into the closure pockets defined between the foils 12 and 14 and the corresponding turned-in parts 16 and 18, respectively, thereof, thereof, generating a complete filling out of the closure pockets.
  • the closure pockets are distended, resulting in that the turned-in parts 16 and 18 defining the closure valve flaps are further pressed against one another creating a permanent closing of the freezing mould bag 10.
  • the permanent closing of the freezing mould bag is further capable of maintaining the freezing mould bag hermetically sealed in case the freezing mould bag is shifted from its position shown in Fig. 3 to a position arranged in a substantially plane orientation on a supporting surface, e.g. a supporting surface of a deep-freezer or a home freezer in order to guarantee that the amount of liquid or water confined within the interior of the freezing mould bag 10 does not to any substantial extent leak from the interior of the freezing mould bag 10 during the freezing of the liquid or water.
