Definitions

  • This invention relates to flexible dispensing containers for limited amounts of liquid which are made from sheets of pliable material sealed around their edges and provided with a narrow outlet channel running through one of the sealed edge sections of the container and terminating near a corner which can be torn off to open the channel and allow the liquid to be dispensed when the container is squeezed.
  • a third object of this invention is to provide a means to accommodate large variations in the internal pressure of the liquid holding pouch due to carbonation.
  • Figure 1 is a perspective view of a flexible liquid container according to the invention.
  • Figure 2 is a partial frontal view of the working face of a container molding plate
  • Figure 3 is a cross-sectional view of a couple of cooperating molding plates
  • Figure 4 is a perspective view of a convex, blister-molding insert
  • Figure 5 is a perspective view of a concave, blister-molding insert
  • Figure 6 is a frontal view of the upper part of a molding plate showing a first alternate configuration
  • Figure 7 is the frontal view of a molding plate showing a second alternate configuration
  • Figure 8 is a diagrammatical and cross- sectional view of an expansion chamber in the deflated condition.
  • Figure 9 is the diagrammatical and cross- sectional view of an inflated expansion chamber.
  • FIG. 1 a flexible liquid container 10 according to the invention.
  • the container is made from two sheets 18 and 19 of pliable synthetic material which has been heat-sealed about their edge and about a carefully delineated area of the upper portion 20 of the container.
  • the unsealed area between the two sheets 18 and 19 form a pouch 13 for holding a fluid, as well as a self-sealing outlet 11, a pouring spout 12 and a expandable ballast chamber 14.
  • FIG 2 illustrates the working face of the upper part of a pair of heat-sealing plates 21 and 22.
  • Each plate is preferably made of a highly heat-conductive metal which, as shown in Figure 3 is bonded to a backplate 23.
  • the backplate acts as a heat distributing element.
  • the backplate 23 may be heated by various well-known means such as embedded resistive elements and the like.
  • Area 24 of the working face of each backplate which corresponds to the liquid-holding pouch 13, the outlet 11 and the spout 12 indicated by stippling in Figure 2 has been etched to a depth of a few milimeters.
  • the channel 26 is relatively long and narrow so that in the absence of strong internal pressure the walls of the resulting outlet tend to collapse against each other and remain closely stuck under the effect of capillarity even after the outlet has been opened by tearing off the corner part 16. It can now be understood that any fluid stored in the pouch 13 can be extracted by two separate means, either by way of the self- sealing outlet 11 once the corner part 16 has been -1-
  • the expandable plastic chamber 14 is formed during the manufacturing process of the container 10 by installing a pair of blister-shaping inserts through line-up balls in the plates 21 and 22.
  • One insert 34 offers a concave area on the working face of the plate 22 while the other insert 33 shows a corresponding convex area 36 which is positioned and dimensioned to nest intimately within the concave area 35 of the other insert 34.
  • the inserts are made from a hard material which has a lower heat conductibility than the material from which the plates 21 and 22 are made. The heat transmitted to the insert as well as other relevant parameters are adjusted to cause the forming of nesting blisters in the two layers of the container material without allowing any material adhesion.
  • Figures 4 and 5 respectively illustrate the shape of the inserts 33 and 34.
  • the threshold between the non-adhesive shaping of the blister and the bonding of the two layers of the synthetic material used in the fabrication of the container depends on the combination of three parameters: heat, pressure and dwell-time. While the dwell-time is common to all areas of the container, the pr-essure applied by the nesting of the two faces 35 and 36 of the inserts may be made different than the pressure applied by the non- etched area 25 of the plates 21 and 22 by carefully contouring and adjusting the faces of the inserts 33 and 34. Similarly the heat transferred to the insert can be adjusted by varying the penetration of the mounting screws 37 and 37A into the body of the inserts 33 and 34 respectively. The choice of insert material between various grades of ceramic and resin will also dictate the amount of heat applied by the insert to form the blister.
  • Figure 6 illustrates a first alternate treatment of the upper part of the forming plates 21. It should be noted that the ovoid insert 38 extend over the cut-off area 31 of the spout 12; thus providing two inlets 39 and 40 into the blister area.
  • Figure 7 illustrates a second alternate embodiment wherein the blister-forming insert 41 is postitioned under the outlet-forming channel 42.
  • the expandable ballast chamber has an inlet near the conjuncture of the inner pouch and the beginning of the self-sealing outlet. Accordingly, once the self-sealing outlet 11 has been used and a portion of the liquid has been evacuated from the pouch, any building of gas pressure in this area will tend to expand the volumetrically variable chamber 44 rather than through the tightly closed outlet 11.
  • the size and shape of the blistered area as well as the gauge and length of outlet can be adjusted to accommodate various types and volumes of carbonated liquid within the pouch 13 and yet allow for an immediate self-sealing of the outlet after first or subsequent drawing of the carbonated drink from the pouch. While the preferred embodiment of the invention has been described and alternate configurations have been suggested, it should be understood that other embodiments may be devised and modifications can be made without departing from the spirit of the invention and the scope of the appended claims.

Abstract

Un récipient distributeur de liquide (10) constitué de feuilles pliables en matériau synthétique comprend un orifice de sortie auto-obturable (11) et un bec verseur (12) qu'on peut l'un et l'autre ouvrir en déchirant l'un des coins du récipient. Le coin intérieur (15) de la poche (13) contenant le liquide qui est adjacent à l'orifice de sortie auto-obturable a été arrondi à distance de la partie déchirable (16), de façon à éviter que la poche ne soit percée par inadvertance. Une chambre tampon dilatable (14) est disposée près de la jointure entre l'orifice de sortie (11) et la poche intérieure (13), afin d'absorber la pression due à l'échappement des gaz de carbonisation, de façon à diminuer la pression qui s'exerce contre l'orifice de sortie auto-obturable (11) et empêcher les fuites, dès que le coin (16) de l'orifice de sortie a été déchiré, sauf lorsqu'une pression supplémentaire est appliquée à la poche (13).
