Definitions

  • the invention relates to packaging for viscous to pasty products, to be stored away from ambient air and intended to be stored under form of regular deposits on a substrate, for example regular layers thin deposited on a support. These may for example be products usually intended to be spread on a slice of bread or any other type of food support.
  • the so-called "spreadable" food products are packaged in different ways depending on the intended use: metal, glass or plastic covered with a cover in case of multiple uses or envelopes made of plastic or metalloplastic films in case single use. Said container, even if it is covered with a lid, does not prevent the product from being subjected from the first opening to the various attacks from ambient air, which can range from simple oxidation to bacterial, cryptogamic or viral attacks.
  • the envelope the lack of rigidity of the spread that it thus coats that his own weakly rigid behavior makes it difficult to tear and open it cleanly.
  • the products contained require the use of an intermediate tool, such as a knife, to be able to be extracted from their packaging and then deposited in the form of a more or less fine layer adhering to a support, typically a slice of bread.
  • an intermediate tool such as a knife
  • the user is located often, especially during trips or short stays away from home, in situations where he cannot easily have said intermediate tool, which prevents him from consuming such products in conditions of comfort and satisfactory cleanliness.
  • handling a flexible tube is not very easy in the sense that the user must press the flexible wall of the tube with one hand to take out the product and direct the nozzle fitted with the dispensing orifice to spread the product in the desired location. This prevents the user from controlling perfectly not only the direction in which the product is projected on its medium but also the speed with which it is distributed.
  • the food products concerned exhibit indeed a behavior viscous in general thixotropic in the sense that it is necessary to provide initially an effort important to overcome the resistance to viscous flow of the product but, once the flow has started, the latter "gets carried away” if the stress exerted is not not immediately significantly reduced. This generally results in massive amount of product arriving on the support. So even if the user manages with one hand to direct the jet well while exerting an effort intense on the flexible skirt, this untimely arrival of food product does not not allow for regular deposits. For example, layers of substantially uniform thickness, it must use a tool intermediate such as the previously mentioned knife.
  • the plaintiff therefore sought, in order to respond to the problems posed above, to develop a packaging process which allows keep the viscous product away from ambient air when used multiple and which allows to distribute along a given direction a controlled amount of product.
  • the object according to the invention is a packaging process for products viscous to pasty food intended to be deposited in the form of deposits regular on a substrate, characterized in that a packaging is used under pressure, comprising an external housing comprising two chambers separated, the first chamber being intended to contain the product food, said first chamber being connected to a valve which controls the flow of product flowing to a nozzle whose opening has the geometry suitable for deposition, in that said first chamber is filled with said food product and in that filling said second chamber with pressurized propellant.
  • the viscous product is separated from the propellant because it is generally better to avoid the latter mixing with the viscous product. Even if he is possible to find a non-aggressive propellant, the latter, by diffusing in the product and then expanding during depression following the distribution, changes the appearance of the dispensed dose. Under such conditions, even if the product is exactly the same, it is presented once distributed often in the form of a foam or a paste whose color and consistency differ from that of the product packaged in packaging usual. A good separation between the propellant and the product is therefore desirable.
  • a propellant pressure typically between 2 and 10 atmospheres at room temperature
  • viscous products such as spreads: processed cheese, liver pate, butter, jam, mayonnaise, mustard, pasty mixtures containing chocolate, almonds and hazelnuts, fruit pastes, condiments, such as Ketchup (registered trademark), etc.
  • the spread has a viscosity which, at room temperature, is typically understood between 10 3 and 10 7 centipoises (between 1 and 10 4 Pa.s).
  • the use according to the invention of a pressure casing proves to be particularly advantageous for products having a viscosity of between 10 2 Pa.s and 4.10 3 Pa.s.
  • the deposition of the food product is carried out directly on a support, typically a slice of bread, by acting on the valve and moving the nozzle over said support, controlling the distance between the dispensing orifice and the support and the speed of movement of the housing relatively to said support.
  • the housing is preferably metallic, steel or aluminum.
  • the valve allows to control the distribution of the product: it goes out under the effect of the propellant pressure transmitted by the wall of the pocket or the piston.
  • the desired form a section cord particular, a layer having a given thickness, etc.
  • the user has more than effortlessly actuating the valve and the product passing through the valve is directed by a distribution conduit towards a nozzle whose distribution orifice has the right shape.
  • the tip is an added piece that fits on the end of the distribution duct exiting the valve, itself crimped on the housing.
  • the container used in the context of this invention has rigid walls: unlike the flexible tubes used previously, the user no longer has to lean on the walls, which made him lose part of his means. Of even, as he uses a valve and not a pump, the user does not have to make some effort to set the viscous product in motion. All this allows him to focus on how he should move the hole above the receiver support, in particular on the distance at which it must place the dispensing orifice relative to the support and on the speed with which it must move the case. The latter is related to the regularity of the deposit, because the quantity of material spreading in one place of the support depends on the speed with which the case is moved by report to said support.
  • the distributor box thus produced offers the consumer a new way spread or spread a viscous product on a support, requiring much less effort than before and thus allowing him to control his gestures with more precision.
  • This new way of doing things presents a clearly playful, original and attractive, while preserving the original appearance of the food product as proposed in the packaging of the prior art.
  • the housing according to the invention gives the user the possibility of being much more precise than with the packaging of prior art.
  • the pressure prevailing in the case due to the propellant changes certainly during the life of the distributor box but it remains appreciably constant during the same distribution, which is all the more appreciable when the user seeks a regular deposit, for example a layer of substantially constant thickness: it just needs to control the speed relative displacement between the nozzle and the support.
  • the product is distributed under pressure with a certain force which the plate on its support and makes it all the more easy to adhere to it that the latter has a certain porosity: under the effect of pressure residual prevailing in the product after its release and speed as well acquired, the viscous product penetrates into the pores of the support, which constitute so many small anchors.
  • a condition minimum to a certain adhesion of the product on its support corresponds to fact that, immediately after being deposited, the product does not detach from the support under the effect of its own weight.
  • the housing obtained according to the invention lends itself particularly well to food products that are spread usually on a slice of bread or other food aid (rusk, cookie, etc ).
  • the nozzle has a rectangular orifice and the deposited layer is of substantially constant thickness.
  • the tip is also provided with a spreader knife.
  • Another object of the invention is the use for the distribution of a product viscous food, in the form of a regular deposit, a pressure packaging comprising an external casing surrounding two separate chambers, the first chamber being intended to contain the product viscous to be dispensed, the second chamber being intended to contain a gas pressurized propellant, said first chamber being connected to a valve controlling the flow of product flowing to a nozzle whose opening has the geometry appropriate to the shape of the deposit, said deposit being performed directly on a support, by action on the valve and using said tip and moving the tip over said support, controlling the distance between the dispensing orifice and the support and the speed of moving the case
  • the figure shows in perspective the case described in the example, in which the user holds a sandwich in one hand and deposits a uniform layer of the other hand using the housing according to the invention.
  • a housing 1 made of aluminum alloy with a capacity of 500 ml, diameter 42 mm and thickness 0.3 mm. It is a two-chamber unit separated by a plastic piston.
  • the first bedroom contains nitrogen under 8 atmosphere, used as propellant.
  • the second room contains the spread, a cream made from a mixture of cocoa and hazelnuts.
  • the housing is fitted with a "large flow valve for pasty product" from the company LINDAL.
  • the valve is surmounted by a nozzle 2 provided with a rectangular dispensing orifice 30 mm wide and 2 mm thick. and extended over 10 mm by a spreading knife 3 .
  • the tip is placed so that the end of the spreader knife is no more distant from the spread than by a distance of approximately 3 mm.
  • the housing is animated with a regular continuous movement so as to obtain a layer of substantially uniform thickness 4.
  • the sandwich 5 is turned over and it is found after one minute that the layer still adheres to its support.
