Description

Bag with at least two compartments tobacconists

The present invention relates to separate conditioning of at least two products, per example the products to be mixed extemporaneously, in particular two hair coloring products such as a dye and a oxidizing

Numerous bottles with two have been proposed compartments, which allow two separate conditioning products to be mixed extemporaneously. These jars are without However relatively complex and expensive to perform.

It is known by the French patent application FR 2 826 641 a device for simultaneous distribution of by at least two products separately conditioned in a first and second bags with flexible walls. This device includes first means that allow to keep the two bags fixed superimposed, so that the respective outlet holes of the bags are arranged in close proximity to each other and some second mobile means with respect to the first means for exert pressure on the two bags, so that they force the output of its contents through the mentioned holes. A device of this type is relatively complicated of use.

The invention provides a solution to the conditioning of at least two products that is relatively simple, inexpensive and practical to use.

The invention comes to this thanks to a bag with two watertight compartments, which comprises first and second opposite main walls and a partition that separates in the Inside the bag the two compartments.

A double bag according to the invention allows the conditioning of two products in a relatively way Simple, reliable and inexpensive.

Advantageously, the bag comprises first and second folding side walls, respectively located at both sides of the partition. These first and second walls sides are for example located on the opposite side one of the another with respect to a longitudinal axis of the partition. A solution of This type facilitates filling. In a variant, the first and second side walls are located on the same side with respect  to a longitudinal axis of the partition.

The presence of folding side walls allows to increase the contents of the bag without increasing the surface of the main walls, which improves the ergonomics of the bag.

In an embodiment of the invention, The first and second folding side walls are incoming. In a variant, the first and second folding side walls are outgoing

Always in an example of realization of the invention, for a portion of at least the length of the bag:

-

the first main wall is attached to a first longitudinal edge of the partition,

-

the second main wall is attached to a second longitudinal edge of the partition, this second edge being opposite to the first,

-

the first side wall joins the first main wall to the second longitudinal edge of the septum and the second side wall joins the second main wall to the first longitudinal edge of the partition.

At least one of the side walls can be folded along a fold line, which can be substantially parallel to the longitudinal axis of the partition.

The bag may comprise a third wall folding side arranged on the same side of the partition as the first side wall, the first and third walls being sides joined each one by one part to the partition and on the other hand to the first main wall.

The bag can comprise a fourth wall folding side arranged on the same side of the partition as the second side wall, the second and fourth side walls being joined each one by one part to the partition and on the other hand to the Second main wall.

The first and fourth side walls can be attached to the same longitudinal edge of the partition. The second and third side walls can be attached to the same edge longitudinal partition.

The bag can be of sensible structure symmetric with respect to its longitudinal axis.

The bag may comprise a terminal distribution, which may be constituted by the assembly and cutting of the main walls, the partition wall and the walls lateral.

The folding line or lines can be extended by at least a portion of the length of the terminal. So, the first second side walls may be folded according to folding lines and these folding lines may extend in at least a portion of the length of the terminal. Lines folding can in particular be extended by more than half of the terminal length

The partition can understand about their faces opposite different materials with for example on one side a material adapted to resist prolonged contact with a hair dye and on the opposite side a material adapted to resist prolonged contact with a hair oxidant.

The main walls and the partition can be assembled by welding.

Also, the side walls and the partition They can be assembled by welding.

At least one of the side walls can be made of the same piece with a main wall.

The two compartments can present some substantially equal contents. The content of each compartment may be for example less than or equal to 40 ml.

The first and second main walls can be formed by at least some flexible sheets that have some composite structures, with for example a metal film, for example aluminum and at least one film of a material thermoplastic

The object of the invention is also according to another of its aspects, a hair coloring procedure in the which are applied on the hair two products respectively contained in the two compartments of a bag such as the defined above, the two products being for example mixed extemporaneously.

The object of the invention is also according to another of its aspects, a bag manufacturing procedure as defined above, in which two overlap flexible sheets intended to form the two main walls, the partition wall and folding side walls, the leaves being intended to form the folded side walls each according at least one fold line, and in which the sheets thus superimposed on a configuration corresponding to the bag to make.

Welding can be done so that leave, on the opposite side of a distribution terminal, an opening that allows filling. The main walls can be separated before filling and you can weld the opening that has Served for filling once the bag has been filled.

The invention may be better understood with the reading the following detailed description of examples of non-limiting realization of it, and with the examination of the attached plan, in which:

- Figure 1 represents in front view a bag made according to the invention,

- Figure 2 represents schematically and partial, in cross section according to II-II, the bag of figure 1,

- Figures 3 and 4 represent respectively, schematically, details III and IV of figure 2,

- figure 5 is a view analogous to figure 1 of a variant embodiment,

- Figures 6 to 9 are analogous views of the Figure 2 of other embodiments.

In the figures, and in particular in figures 3 and 4, the different elements have not necessarily been represented respecting the real proportions, with the purpose of clarity of the drawing

The double bag 1 represented in figures 1 and 2 has a general elongated shape along a longitudinal axis X, with a body 12 extended at one end by a terminal of distribution 2 that can be cut when the use according to line C for example to allow the user empty the contents of the bag.

In the illustrated example, body 12 presents a substantially constant width but it could be otherwise without leaving the scope of the present invention. Body 12 It could, for example, present a trapezoidal or oval shape.

Bag 1 defines a first compartment 3 and a second compartment 4 intended to contain respectively first and second products P_ {1} and P_ {2} that must be stored separately and for example to mix extemporaneously

It can be for example a dye and a hair coloring oxidant.

Various forms can be given to the bag and various contents, for example between 1 and 40 ml per compartment, even between 1 ml and 80 ml or more, for example eleven.

If necessary, the double bag can serve to perform a coloring test on a wick, and each compartment then presents a content of for example 1 ml.

Bag 1 comprises first 5 and second 6 main walls, first 7 and second 8 side walls folding and an internal partition that separates inside the bag 1 compartments 3 and 4.

The partition 9 has about first 10 and second 11 longitudinal edges located opposite each other and first and second faces 28 and 29 respectively located in the sides of the first 3 and second 4 compartments.

The first main wall 5 presents a first longitudinal edge 13 that is assembled in the example of the Figure 2 to the first longitudinal edge 10 of the partition 9 on the side of face 28 and a second longitudinal edge 15 that is assembled to a first edge 17 of the first side wall 7, the edge being opposite 18 of this one assembled with the second longitudinal edge 11 of the partition 9 of the side of the face 28 as well.

Always in the example of figure 2, the second main wall 6 has a first longitudinal edge 20 that is assembled to an edge 21 of the second side wall 8, the opposite edge 22 thereof attached to the first longitudinal edge 10 of the partition 9 on the side of face 29 and the second main wall 6 it has a second longitudinal edge 23 that is assembled with the second longitudinal edge 11 of the partition 9, on the side of the face 29 too.

Each side wall 7 or 8 is folded according to a folding line 24 substantially parallel to the longitudinal axis X in the example considered, and that can be placed substantially equal distance from edges 17 and 18 or 21 and 22.

In the example considered, bag 1 presents, in a portion at least of its length, a structure generally symmetric with respect to the X axis, as can be seen in Figure 2. It could be otherwise and you could, for example, have uneven side walls 7 and 8, depending on, for example, the respective contents of compartments 3 and 4.

When bag 1 is empty, the walls main 5 and 6 are against the partition 9 and the walls sides 7 and 8 are folded over themselves. When the bag is full, side walls 7 and 8 have been deployed in the manner of a bellows

They can be used to make the walls main 5, 6, side walls 7, 8 and partition 9 ones flexible sheets that can each have a structure multilayer, depending in particular on the nature of the Products contained inside the bag.

The sheets used can comprise example a polyethylene film, polyamide, a varnish suitable, a layer of aluminum and some overlays of different materials, with for example a composite structure comprising a layer of glue between a polyethylene film and a layer of aluminum.

Preferably, the sheets used for perform the different walls and the partition will be chosen from so that they can be assembled by welding, by application localized heat.

You can for example use some sheets that they have different physicochemical properties to constitute  on the one hand the first main wall 5 and the first wall side 7 and on the other hand the second main wall 6 and the second side wall 8.

Also, partition 9 may present in its opposite faces 28 and 29 different materials.

The partition 9 may for example be constituted by a sheet comprising two films laminated together, consisting of materials respectively suitable for contact with the products contained in compartments 3 and Four.

The partition 9 can also present the composite structure depicted in figure 3, comprising a intermediate support film 30 coated by each of its faces for films 31 and 32 suitable for the conditioning of products 3 and 4.

Each main wall 5 or 6 or side wall 7 or 8 may present the composite structure represented in the figure 4, comprising an outer film 33 and an inner film 34 of a suitable material to come into contact with the product content in the associated compartment.

The outer movie 33, like the movie intermediate 30 of partition 9, can for example be a layer of aluminum and one of the coating films 31, 32 or 34 can be of a thermoplastic material.

To make the bag 1, you can for example from five elements in sheets, conditioned in coil, which overlap, reaching the sheets intended to form the walls sides 7 and 8 in the folded state to the welding post.

Terminal 2 is located between the lines of folded 24 when the bag is empty and flattened. The walls main 5 and 6 are respectively assembled with faces 28 and 29 of partition 9 on contour 43 of terminal 2.

The bag is also welded on the periphery 40 of body 12 with the exception of an area 41 located on the edge opposite terminal 2, between folding lines 24 and remotely of these, this area 41 being delimited by some dotted in the Figure 1.

Upon arrival at the filling station, the walls main 5 and 6 can be separated from each other, for example by means of suction cups, and cannulas introduced in the compartments 3 and 4 to proceed to filling.

After filling, zone 41 can be closed by welding so that the two are sealed products P_ {1} and P_ {2} in compartments 3 and 4.

When the use takes place, the user you can section terminal 2 so that it releases two holes of distribution that lead respectively to compartments 3 and 4 and separated by partition 9.

To distribute the contents of the bag, the user can press on the main walls 5 and 6 of so that the approximate. The products P_ {1} and P_ {2} contained in compartments 3 and 4 they can be mixed directly on the hair or in a variant in an attached container, before of the application on the hair.

Of course, the invention is not limited to exemplary embodiment that has just been described.

In the embodiment variant illustrated in the Figure 5, the folding lines 24 are sufficiently close to the longitudinal axis X to extend over a portion of the length of terminal 2, for example more than half of its length, such as It has been illustrated.

Thus, when terminal 2 is sectioned according to the line C, the distribution hole can be enlarged by deployed from side walls 7 and 8, which reduces loss loading and can facilitate the flow of products P_ {1} and P_ {2}.

The possibility of make the main walls 5 and 6 respectively of a single piece with side walls 7 and 8.

The possibility of have side walls 7 and 8 that join the same edge longitudinal 11 of the partition 9. The second main wall 6 is linked in this way by its edge 20 to the longitudinal edge 10 of the partition 9 and its edge 23 to the edge 21 of the folding side wall 8, the edge 22 of the side wall 8 being attached to the edge longitudinal 11 of the partition 9.

The possibility has been illustrated in figure 8 For the bag to comprise more than two folding side walls, for example four folding side walls arranged two to two on either side of partition 9, thus forming compartments 3 and 4 each with a bellows.

The first main wall 5 is joined in the example considered to a third folding side wall 50 for its edge 13. The third folding side wall 50 has an edge 51 attached to the first main wall 5 and an opposite edge 52 attached to the longitudinal edge 10 of the partition 9. The second main wall 6 it is joined by its edge 23 to the edge 54 of a fourth side wall folding 55, which is joined by its edge 56 opposite edge 54 to the longitudinal edge 11 of the partition 9.

In the illustrated example, bag 1 has a general symmetric structure with respect to the longitudinal axis X but it could be differently and in particular the first 7 and third 50 side walls could have dimensions different from the second 8 and fourth 55 side walls, in particular if the contents of compartments 3 and 4 must be different.

The possibility has been illustrated in figure 9 for folding side walls 7 and 8 of presenting some shapes Outgoing rather than incoming.

The characteristics of the different modes of realization can be combined.

For example, in the example in Figure 7, the main walls 5 and side 7 can be made of one piece, as well as the main walls 6 and side 8. It can be the same in the examples of figures 8 and 9.

In the example of figure 7, the walls Lateral can be outgoing rather than incoming. Can also  be the same in the example in figure 8.

If necessary, they can be used to make partition 9 two sheets applied at least partially,  in particular along its edges.
