FR2518500A1 - Sachet type graduated container e.g. for dietetic food - has opaque plastics walls with soldered edges and transparent plastics scale e.g. for calorie count - Google Patents

Abstract

One of the walls of the container accommodates a window, which extends either vertically or obliquely over part or the entire portion of the wall. The window is provided with at least one marker and is sufficiently translucent to permit visualisation of the filling liq. The markers may be used to indicate the calorific value of partic. food substance. The container is formed of an opaque plastics envelope soldered along its lateral and upper edges. The window is formed along the lateral edge at one of the envelope walls. In manufacture, a food substance to be diluted extemporaneously is introduced into the envelope and the remaining unsoldered edge is soldered. During use, the upper edge of the envelope is cut for emptying into a recipient.

Description

 The present invention relates to a generally non-transparent packaging for material to be diluted, such as a powdered food.

 Food preparations are already known which, once the preparation has been poured into a container, serve as a measure for the quantity of water, milk, etc. to be added to it.

 These packages usually consist of a paper bag which carries a filling mark for measuring the liquid. Or else this mark is outside the.

pocket and the level of the liquid is vaguely estimated through the paper, or else it is inside and the user judges, from above, the agreement between the level of the liquid and the mark. In both cases, the quantity of liquid measured is approximate, which does not matter in the case of food preparation. On the other hand, when it is a dietary food used for example for a nutritional resuscitation, it is essential that the dilution of the food, which regulates in particular its caloric value per unit of volume, is more exactly known .

 One could, for this purpose, replace the paper bags with a bag made of a transparent material, such as a transparent plastic, but more often than not this is undesirable for the following reasons.

 Many components of dietetic foods, such as vitamins, certain easily oxidizable fats, certain pigments, etc. are sensitive to light. It is therefore necessary to use packaging, if not completely opaque, at least not transparent.

 From a practical point of view, the information printed on the packaging is obviously better read if it is not transparent.

 Finally, on the aesthetic level, the manufacturer may wish to affix a decoration or its mark in one or more dark colors flat, which also prevents the use of transparent packaging. We therefore generally use a packaging with a certain opacity.

 To nevertheless allow the use of this packaging as a dosing container for a quantity of liquid to be added to the food, the invention provides that one of its food, a more or less large quantity of liquid is measured in the bag 1 .

 For an isocaloric diet (1 cal / ml, for example, fill the sachet up to graduation 1 (case of the figure). If the desired caloric concentration is other, for example 0.9 cal / ml or 1.5 cal / ml, filling is carried out up to the corresponding mark, the transparency of the window making it possible to see the level exactly in all cases. It is clear that the user can carry out a precise filling by placing the chosen mark at the level of his eye (line x, x) as one should do when properly using a graduated liquid measuring instrument.

The packaging according to the invention. can be used for food or non-food products, a non-exhaustive list of which is given below, these products can be presented in tablets, tablets, powders, granules, flakes, etc.
I- Common food products
- broths and soups
- breakfasts
- custards, desserts, instant desserts, creams
- mixes for ice creams and sorbets
- milk and milk derivatives
- edentulous foods
- food for the elderly
- food for explorers, polar missions, etc.

 - food for airplane pilots, cosmonauts, etc.

-foods of the "combat rations" type
life"
- food intended to constitute food reserves
civil or military, in case of war, fami
natural disasters, etc.
- food for pregnant or breastfeeding women
- powders (and derivatives of fruits, vegetables, fruit juices,
vegetable juices, aromatic plants and spices, coffees,
teas, chicory, infusion plants
- flavored sugars
- common aromatic complexes
- stuffing (for example to garnish poultry, tomatoes,
etc ..) croquettes and dumplings
- dauphine potatoes
- pies, croustades, pasta for pancakes, donuts, with walls at least has a window extending vertically or obliquely over all or part of the height of this wall, which window has at least one filling mark and is sufficiently translucent to allow to see, through it, the level of a liquid poured into the packaging,
Thus, it is possible to see exactly the filling level through the window which, preferably, will be transparent.

 We have certainly already provided cardboard packaging or other material with a fairly large opening, closed by a sheet of cellophane, revealing the contents of the packaging. In this case, however, it is a matter of allowing the buyer to see the product he is buying (pasta, lentils) and not of allowing the packaging to be used as a dosing device.

 In a preferred embodiment, the packaging window according to the invention has several filling marks giving, depending on the quantity of liquid added, the variation of a characteristic of the diluted food.

 This characteristic of the diluted food can be for example its caloric value per unit of volume.

 An embodiment of the invention is described below with reference to the accompanying drawing, the single figure of which shows packaging after opening and emptying of its content into a container.

 The packaging is formed by a pocket 1 of non-transparent plastic material welded along its lateral 2 and upper edges 3. Along the edge 2, one of the walls 4 of the pocket has a narrow window 5 extending over part of the height of the packaging and comprising marks 6.

In the present case, the marks 6 are constituted by an extension, on the window 5, of the non-transparent part of the wall 4. Each mark 6 corresponds to a numerical value which, in the example shown, is the caloric value of the food once diluted by the volume of liquid necessary for filling up to the mark considered.

 The packaging according to the invention is used as follows.

During manufacture, a quantity of food to be diluted extemporaneously is introduced into the bag 1 and the edge 3 is welded. At the time of use, the upper part of the bag 1 is cut and its contents emptied into a container. According to the dilution and therefore, according to the caloric value that we intend to give
pudding, soufflés, cakes, cookies and pastry
various laughs
- mashed potatoes, split peas, lentils,
chickpeas, etc.

IV- Products other than food
1 / coated,
2 / dyes,
3 / pigments,

etc ...

 It goes without saying that the invention is not limited to the embodiment described and shown.

 In particular, the packaging window could be oblique instead of being vertical. Depending on the nature of the packaging material, the window may not be obtained, as in the example, by means of a reserve provided during the printing of the sachet (which is only possible if the material is originally transparent or sufficiently translucent, but by cutting an opening in the packaging material if the latter is opaque or insufficiently translucent, this opening then being closed, for example, by welding or bonding of a film, of a film, etc. having the desired translucency characteristics. This makes it possible to extend the application of the invention to packaging in aluminum foil, baking paper, tinted rubber dark, etc ...

 The packaging is not necessarily flexible, it could be semi-flexible, semi-rigid or rigid (for example in tinplate, in polystyrene called "crystal", etc.

 I1 could also take a form other than a pocket, for example, be a sachet, a tray, a tube, a pot, etc ...
