FR2545064A1 - PACKAGING WITH INTERNAL RECEPTACLE FOR PACKING TWO OR MORE TWO DIFFERENT CHEMICALS MUTUALLY REACTING - Google Patents

Abstract

THE INVENTION RELATES TO AN INTERNAL RECEPTACLE PACKAGING FOR PACKING TWO OR MORE THAN TWO DIFFERENT CHEMICALS THAT REACT MUTUALLY. THIS PACKAGING CONSISTS OF A CARDBOARD ENVELOPE IN THE FORM OF A FOLDING BOX 11, AND OF AN INTERNAL RECEPTACLE 12 IN A SHEET OF PLASTIC MATERIAL RECEIVING THE CHEMICALS. THIS RECEPTACLE 12 IS SUBDIVIDED BY A SEPARATING PARTITION 13 INTO PARTIAL COMPARTMENTS 14, 15 EACH CONTAINING A BAG WITH PRODUCT. PARTITION 13 IS CONNECTED BY MEANS OF TWO FLAPS 16 TO THE INTERNAL FACE OF THE WALL OF THE RECEPTACLE. THE BAGS CONTAINING THE CHEMICAL PRODUCTS PREFERABLY CONSIST OF WATER-SOLUBLE SHEETS. APPLICATION IN PARTICULAR TO THE PACKAGING OF REACTIVE SUBSTANCES.

Description

The present invention relates to an inner receptacle package for

  wrapping two or more different mutually reactive chemicals, including an outer cardboard wrapper in the form of a collapsible box, and an inner receptacle formed by a casing and consisting of a sheet of plastic material optionally lined with a another material, for example an aluminum foil, this packaging being

  first delivered in a flat state to the packaging plant.

  then be trained, filled and closed.

  In some fields of application, chemicals are used which, directly before their use, are made by mixing different substances These substances very often react, that is why it is necessary to pack them separately from each other and to deliver them in this condition to the consumer

  or the user, respectively.

  So far, it is usual to pack such

  substances in two or possibly more than two

  This process has proved to be disadvantageous, hence the desire to be able to offer the substances packaged in a single single packaging. However, it is important in this case that the substances remain mutually separated, even when they are each packed in This separation must be absolutely safe in order to avoid untimely reactions of the substances with each other In certain circumstances, the receptacles in which the substances are packaged must not even be juxtaposed. There is in particular a risk of formation. unwanted mixtures and

  reactions when receptacles containing chemical products

  consist of the simple use of these products.

  chemical substances, in a material which is soluble in water or which loses its structure and function under the influence of moisture, a material which, with respect to the stresses imposed during

  transcort therefore has a lower resistance

  that other suitable packaging materials

to be used elsewhere.

  It is an object of the invention to provide an individual package in which the two or more relevant substances can be packaged together and which surely avoids direct contact of these substances or their envelopes. hermetic,

  especially moisture-proof, closable and deliverable

  ble at the packing plant in the flattened state.

  According to the invention, to achieve this object,

  it is proposed to make a container with an inter-

  ne of the aforementioned type, such that there is in the inner receptacle at least one separating partition which subdividing the internal space of this receptacle into juxtaposed partial compartments enclosing the chemicals wrapped by means of packing materials dissolving in particular under the influence of moisture, is fixed by means of two flaps with two mutually opposite surfaces of the wall of said inner receptacle This separating partition has the same height as the collapsible box surrounding the inner receptacle The making of such internal receptacle packaging takes place from the

  classical way known per se, that is to say that the

  its separator is simply inserted before the training

  of the hose constituting the internal receptacle and then, during the formation of this hose, connected by its

  two flaps to the inner faces of the hose or receptacle.

  Preferably, both the separating partition located in the inner receptacle and the side wall of the package parallel to this separating partition are provided with a folding groove extending over the height of

  packing along its median axis, and along the

  which the side walls and the separating partition consider

  are folded when the packaging is lying flat For the filling of the packaging, it is erected

  considered were introduced into the compartments

  of the inner space of the internal receptacle of

  separate packaging by the separating partitions

  If it proves necessary to provide isolation

  additionally provided at their upper ends and / cu less

  with a bottom lug and cover that is hinged to it. The invention will now be described in more detail by way of non-limiting example, with reference to the appended drawing in which:

  As can be seen from FIG. 1, a folding cardboard outer box 11 contains an internal receptacle 12 whose interior space is subdivided, by means of a separating partition 13, into two partial compartments 14 and 15 each receiving the same. one of the bags filled with chemicals The separating partition 13 is connected, for example glued, sealed or welded to the inner face of the wall

  of the receptacle 12 by means of two flaps 16.

  To allow a flat transport of the package before filling, the partition wall 13 as well as narrow side walls 17 of the collapsible box 11, parallel to this partition, have grooves or

  respective longitudinal grooves 18 and 19 along the

  these elements are folded, as shown in Figure

  re 2 which is a plan view of the package lying flat, said side walls 17 being bent outward and the septéséparatrice 13 being inflected

on one side or the other.

  Advantageously, in order to form the inner receptacle

  12, the sheet material casing is closed at one end by means of a sealing or sealing bead in the vicinity of its bottom and is attached at least in points at its lower end to the inner faces of the sheet material. In this way, when this foldable box is erected, the bottom of the package is automatically formed, which requires less

  manual interventions as usual.

  It goes without saying that many modifications can be made to the packaging described and shown, without

depart from the scope of the invention.
