Definitions

  • the subject of the present invention is an assembly comprising a flexible packaging for liquid product and means for withdrawing the packaged product, in which the packaging has a bottom, a wall, and a closed upper end intended to be opened, and the means for racking form in the packaging a channel adjacent to its wall and extended from an open lower end close to the bottom of the packaging to the closed upper end thereof.
  • the flexible packaging has, substantially like the recovered glass bottle, the lowest charges for environment, considered in its simplest form, that is to say in the form of a sealed bag to be torn or cut to extract the product contained therein, and then to be discarded.
  • these wineskins are generally equipped with a suspension means constituted by a strap of rope or leather.
  • a flexible packaging is described, provided internally with a channel adjacent to its wall and with an elastic core.
  • the channel is produced by wall welding and extends from an open end close to the bottom of the packaging to the closed upper end of the latter which is intended to be open to withdraw the packaged product.
  • the elastic core acts as a pump for the ejection of the product and, above all, for its aspiration when the pressure is released after a withdrawal in order to close the lips of the upper opening of the channel by sucking the liquid it contains .
  • the liquid is reintroduced in the mass of liquid remaining in the packaging at each racking.
  • the invention aims to improve the shelf life of a liquid food product in a flexible package, after opening the latter, and to facilitate the racking operation, while retaining the economic and ecological advantages that this type of packaging presents.
  • the section of the channel formed by the clamp being necessarily reduced compared to that of the packaging, it is easy for the consumer, after removal of the desired quantity of liquid product, to close its upper end, by example using a clothespin or paperclip, and place the packaging in an upright position in any container.
  • the product remaining in the packaging is not in contact with air and only a very small quantity of this product, corresponding substantially to the cross section of the channel, was brought into contact with air during sampling.
  • the clamp it can be put in place at the packaging or by the user himself. In the latter case, it is obvious that the assistant clamp, once in the possession of the user, can be kept by him for later uses with other packaging of the same type. And this makes this clip, which already allows simple manufacturing of the packaging, hardly accounts for environmental packaging costs.
  • the packaging of the first embodiment shown in Figures 1 and 2 is in the form of a substantially polyhedral bag with developable walls, obtained by folding and heat-bonding the junction edges 2 and 3 of a sheet of material.
  • flexible synthetic such as for example a low density polyethylene or a sandwich of plastics and aluminum, depending on the consumable liquid product to be packaged. It can be produced in the usual way, for example by shaping and tubular welding from one or more coils.
  • the packaging has a channel 14 adjacent to a wall 6 which here forms one side of the packaging, and which is extended vertically from a first end 7 located in and near the bottom of the packaging to a second end 8 located at the top and out of the packaging.
  • the channel 14 is formed and limited along its extent by a pinch line 9 produced by the action of a clamp 13, joining at the top the junction edge 2 of the walls of the package and leaving a small passage below. 10 communicating with compartment 4.
  • the upper end of channel 14 is thus closed and the packaged liquid fills compartment 4 and channel 14, these two elements communicating through passage 10.
  • the closed top of the channel 14 which is intended to be opened to allow the withdrawal of the packaged liquid product, for example by cutting using a pair of scissors along a cutting line 11 indicated by a sign affixed to it which, at the same time, serves as an element of distinction between the top and the bottom of the packaging.
  • the location of the cutting line 11 is provided so that only the channel 14 is open, without being able to communicate with the compartment 4, and the cross section of the channel 14 is provided sufficiently reduced, depending on the degree of fluidity of the packaged liquid product. , to avoid too much withdrawal rate, and also to allow it to be closed, after each withdrawal of product, using a simple means accessible to all consumers, such as for example a clothespin or a paper clip.
  • the shape of the packaging is asymmetrical here thanks to two retracted corners forming two bellows 12 on the side opposite to the channel 14, which gives the latter two projecting ends.
  • the upper projection forms a practical pouring spout for the consumer and the lower projection a receptacle making it possible to take up almost all of the liquid product contained in the packaging without it being brought into contact with air, exception, however, of a very small quantity corresponding to the cross section of channel 14.
  • the channel 14 acts as a siphon preventing any entry of air into the compartment 4, the product necessarily having to pass through the passage 10, at the bottom of this channel, while the volume of this compartment decreases accordingly, under the effect of atmospheric pressure.
  • the consumer can place the packaging in any container, preferably in a vertical position, or else suspend it by its upper border 2, without having to empty it of its content.
  • the consumable liquid product remaining in the packaging is thus unvented and non-oxidized, its taste and aromas are preserved and its shelf life extended.
  • the channel 14 is formed by the clamp 13 independent of the packaging, intended to be associated with it at least by the consumer at the time of use, if not sold with him.
  • the clamp 13 is constituted by a tube split over its entire length and the channel 14 is formed by bringing together and pinching two parts remote from the wall constituting the side of the packaging opposite the bellows 12 by the action of this clamp 13, as it is threaded around and along this side.
  • the upper end 15 of the tube forming the clamp 13 is cut in a miter to facilitate the opening by cutting of the upper end of the channel 14 after its installation, and the length of this tube is provided to leave a communication passage between the channel and the compartment thus formed, as the passage 10 shown in FIG. 1.
  • the essential function of the clamp 13, which consists of simply and advantageously forming the packaging channel, can be extended to other subsidiary functions which are beneficial to the consumer, by developing its structure.
  • Figure 3 shows a second embodiment in which the clamp is intended to be associated with a packaging 25 of the same kind as that of Figure 2 to form its channel, but whose structure is developed to at the same time constitute a support to hang or hang.
  • This clamp which is particularly suitable for flexible packages of small capacity, is composed of a pair of vertical jaws 26 extended over the height of the package 25 and articulated at their upper and lower parts by a horizontal articulation 27 integrating a spring clamp, not visible, above and below this package, like a pair of scissors.
  • each jaw 26 is connected beyond the articulation 27, by a hoop 28 surrounding the side of the bellows 12 opposite to the side enclosed by the two jaws 26.
  • the active clamping parts of the two jaws 26 are extended and shaped so that they can pinch the channel 14, in the same way so that by the clamp 13 of the first embodiment.
  • each arch 28 has a lower projection 29 intended to compensate for the additional thickness formed by the articulation 27.
  • the package 25 carries, marked along its side intended to form the channel 14, lines for locating the area to be pinched, as well as the cut line 11.
  • the packaging 25 is introduced between the two arches 28, the two jaws 26 are spread by manual pressure on these arches 28 and released for tightening on the aforementioned locating lines, to form channel 14.
  • the second embodiment comprises a clamp shown in the open position in FIG. 4 and in the closed service position in FIG. 5, preferably suitable for flexible packaging of medium to large capacity, the general shape of which has been shown to be identical to that of the packaging already shown in Figures 1 and 2 in a spirit of simplification.
  • This clamp is composed of two parts 30 and 31 hinged together by a hinge 32 joining their bases 33 forming two support feet, and which each have a side cheek 34 and a front cheek 35, the latter defining a clamping jaw 36 intended to form the channel 14 of a package 37 of the aforementioned kind to meet the corresponding jaw of the other part, when this clamp is closed.
  • the upper parts of the lateral cheeks 34 of the two parts 30 and 31 form two gripping plates 38 and 39 comprising force interpenetration means constituted on one side by pins 40 integral with the plate 38 and on the other side by corresponding holes 41 drilled in the plate 39.
  • the plate 39 carries a stiffener 42 in a cap, curved downward, on the side opposite to the jaws 36, to constitute a handling handle 43.
  • the gripping plate 38, respectively 39 and the jaw 36 of each of the two parts 30 and 31 are inscribed substantially in a plane containing the longitudinal axis of the hinge 32, so that when the clamp is closed these gripping plates and these jaws apply well both against the upper edge 12 of the packaging and the two walls on its side intended to form the channel 14.
  • the upper edge 2 of the packaging 37 includes notches 44 in the form of a U intended to be crossed by the pins 40 of the plate 38 when the packaging is placed between the two parts of the clamp.
  • two marking lines 45 can advantageously be provided on the packaging to facilitate positioning precise jaws 36, given its flexibility.
  • the stiffener 42 facilitates the manual forcing of the pins 40 of the plate 38 through the notches 44 of the packaging and in the holes 41 of the plate 39.
  • This assembly placed on its feet 33 is stable and ensures good retention of the flexible packaging which is thus suspended by the upper edge 2 between the two gripping plates 38 and 39. It is also well retained between the cheeks 34 and 35 and the jaws 36 during the pouring of the liquid product, and this pouring is facilitated by the use of the handle 43.
  • pliers can be constituted in a simple, light and economical manner by two plastic shells. It can constitute for the consumer, as well as the tongs shown in FIG. 3, a usual kitchen object that he can keep and reuse. It can also be made of all kinds of materials since it will in principle never get dirty, not coming into contact with the contents of the packaging, which represents a clear advantage compared to other kitchen utensils.
  • the side cheeks 34 of this clamp can be fitted, in a variant not shown, with two horizontal pins intended to rest in the vertical forks with a suitable support. In this way, the consumer can use it by simply tilting the packaging.
  • a hinge is no longer provided at the bottom of the side walls 34 but above the gripping plates 38 and 39.
  • a snap-fit retainer located between the feet 33 is planned.
  • the gripping means 40-41 can be replaced by horizontal striations, which avoids the need for the notches 44 of the upper edge 2 of the packaging 37.
