Description

Set of first and second containers

The present invention relates to an assembly comprising a first container sized to contain a quantity of a material, in particular a material for the construction such as mortar, concrete, adhesive mortar, glue, or plaster, which together comprises a second container arranged to contain a liquid to be added to said material such that the mixture of the liquid and the material makes this material at least temporarily pasty, which second container has a first indication placed at a first height measured at from a bottom of the second container and indicating a volume of liquid contained between said bottom and the first height where the first indication is placed.

Such an assembly is known from patent DE 899 618. The known assembly comprises in particular a first container, which contains wet material, and a second container, which contains a quantity of liquid, in particular water . Mixing the wet material with water gives a pasty material contained in the first container. The second container is formed by a tank with a tap and indications to adjust the volume of water to add to the wet material. This adjustment of the volume of water is performed after measuring the moisture content of the wet material present in the first container. Thus, a sufficiently pasty material is obtained which is ready for its implementation and which possesses the properties required for this implementation.

A problem of the known assembly is that it is necessary to measure the electrical resistance of the wet material present in the first container to determine its moisture content and then adjust the amount of water in the mixture to obtain the properties required for this purpose. Implementation. The prior art teaches to adjust the moisture content of a material that is already in the wet state. This solution is impractical, especially if it is to be used on site because it requires not only appropriate equipment, skills, but also time, which makes it expensive. It is therefore likely that on site the assembly following the state of the art will not be used, because users will not take the time to make the imposed measurements. The object of the invention is to provide an assembly of a first and a second container which makes it easier and simpler to dispense the liquid without first having to measure the moisture content of a substance at the same time. wet state. To this end an assembly according to the invention is characterized in that the second container is formed by a foldable bag and / or rollable made of a flexible material so as to deform during its filling, which volume corresponds to a prescribed dose liquid to be added to said quantity of material, which is in the dry state, to make it pasty. Contrary to the teaching of the prior art, which teaches adding the liquid to the wet material, the present invention teaches adding the liquid to the dry material. The fact that the first indication indicates a volume which corresponds to a prescribed dose of liquid to be added to the said quantity of dry matter to make it pasty allows an easy and rapid assay of the predetermined volume of liquid to be added and which is directly related, in particular with the quantity and type of dry matter present in the first container and this without using measurements. It will be enough for the user to fill the second container with liquid up to the height indicated by the first indication and to mix this volume of liquid with the dry matter to make it pasty and ready for use. The use of a collapsible and / or rollable bag made of a flexible material makes it easy to attach it to the first container without taking up much space during storage or transport. This also allows to sell the whole as a whole in the same package. Thus the user has at hand a cost-effective, space-saving and reliable means that will allow him to correctly dose the liquid to be added to the dry matter.

A first embodiment of an assembly according to the invention is characterized in that the second container is made of a transparent material, in particular a transparent plastic material. Thus one can see through the second container, which facilitates to monitor the filling in liquid and thus to see better when the volume of liquid will correspond to the prescribed dose.

A second embodiment of an assembly according to the invention is characterized in that the second container comprises a series of second indications arranged according to a reading scale whose graduations represent in each case a fraction of said dose. It often happens, for example for repair work, that one does not need the entire volume of dry matter present in the first container. Since the dose of liquid indicated by the first indication corresponds to that required for the entire volume of the dry matter, the presence of a series of second indications, which correspond to fractions of this dose, will considerably facilitate the task of the user who will use only a fraction of the material present in the first container.

A third embodiment of an assembly according to the invention is characterized in that said indication is applied all around the second container. This greatly reduces errors that would be due to a position of the indication that would not be perfectly horizontal.

A fourth embodiment of an assembly according to the invention is characterized in that said indication is formed by a line. A line is easy to apply and clearly visible.

A fifth embodiment of an assembly according to the invention is characterized in that at least the first indication is accompanied by an auxiliary indication indicating a margin of tolerance for said volume of liquid, in particular an auxiliary indication indicating a minimum volume. and a maximum volume of the liquid. Parameters, such as ambient temperature or humidity, or a tolerance indicated by the manufacturer of the dry matter, may play a role in the determination of the liquid. The presence of such an auxiliary indication makes it possible to take these parameters into account when dosing in liquid.

A sixth embodiment of an assembly according to the invention is characterized in that the second container comprises means for suspending it from a support. It is thus easy to hang the second container, for example during its filling.

A seventh embodiment of an assembly according to the invention is characterized in that said means comprises at least one through perforation at least one wall of the bag and located near an edge of the bag opposite that of the bottom. The perforation is easy to make and allows to easily hang the second container to a support, such as a wall. The invention will now be described in more detail with the aid of the drawings which illustrate an embodiment of an assembly according to the invention. In the drawings:

Figure 1 illustrates the assembly of the first 1 and the second 2 container. The first container is for example formed by a paper or plastic bag, or a cardboard box. The first container is sized to hold a quantity of dry matter, for example 1 kg, 10 kg or 25 kg. The dry material is preferably a material for the construction such as mortar, concrete, adhesive mortar, glue, or plaster. Of course the invention can also be applied to first containers containing other dry materials such as flour, powdered pudding, etc .... The second container 2 is arranged to contain a liquid to be added to said dry material so that the mixture of the liquid and the material makes the material dry at least temporarily pasty. In the example illustrated in Figure 1 the second container is housed inside the first container (shown in dotted lines). It goes without saying that this is a possible embodiment, but it is for example also possible to put the second container on the outer casing of the first container, for example by gluing, or to deliver the first and the second container as separate entities, where appropriate in the same package. It would also be possible to place the two containers next to each other and to wrap them in a plastic film. It could also only deliver a second container for several first containers that contain the same dry matter.

The second container is a container made of a flexible material, particularly a flexible plastic material or plasticized paper. The second container is preferably made of a transparent material, such as transparent plastic. Thus one can see the contents of the second container through its wall. The second container is preferably formed by a foldable and / or rollable bag. The advantage of folding and / or winding the bag is that it facilitates firstly the storage of the second container in or with the first container and that on the other hand further reduces the storage volume. Being able to fold and / or wrap the bag also makes it easier to store after use. The bag will preferably be a flat bag that will deform when it is filled with liquid.

The second container preferably comprises a means 4 for suspending it with a fastener 10 to a support 9, as illustrated in FIG. 5. This support is for example formed by a post or a wall 9. Said means is formed by at least one perforation passing through at least the wall of the bag and located near an edge of the bag opposite that of a bottom 11 of the bag. As illustrated in Figure 6, there at least one perforation is centered on the vertical central axis of the bag 2 to ensure that the bag does not swing to the right or left when suspended and filled. If necessary the perforation can also completely cross the bag to obtain two perforations on the same bag which will allow to suspend the bag with the first perforation 4 and use the second perforation 4 'to facilitate gripping bag and keep it open when adding the liquid.

As illustrated in Figure 2 the second container has a first indication 3 placed at a first height h measured from the bottom of the second container. This first indication indicates that the volume of liquid contained between the bottom and the first height h where the first indication is placed, corresponds to a prescribed dose of liquid and attributed to said amount of material to make pasty. For example, if the first container contains 1kg of mortar for which it is prescribed that must be added 0.3 liter of water to make pasty and able to brick masonry, the first indication will be placed at a height h which corresponds to a volume of water of 0.3 liter between the bottom of the second container and the place where the first indication is applied.

For example, when you want to make mortar it will be enough to fill the second water container up to the height h to have the required amount of water. Since the second container is made of a flexible material, it will deform as it is filled with the liquid. This filling will indeed cause that the second container will inflate under the effect of the thrust exerted by the liquid on the walls of the container. The user will see the liquid filling the second container and it can easily stop the filling when the liquid has reached the level indicated by the first indication, this will have the additional advantage of not wasting liquid. This quantity of well-dosed water will then be mixed with all the dry matter contained in the first container to obtain the pasty material desired and ready for use.

The first indication is preferably formed by a line, for example a black line drawn or printed on the second container, as shown in Figures 2 to 5 and 7. The application of a line on the second container is for example by a stamp containing ink. Said first indication is preferably applied all around the second container so as to limit the liquid dosing errors, which would be due to a position of the indication which would not be perfectly horizontal, it being understood that the vertical axis has in similar condition does not extend perfectly vertically. This is particularly the case when the indications are formed by a line drawn on a bag of transparent material. The presence of the line all around will indeed make it possible to see if the bag is correctly positioned. If the bag is not positioned correctly, the upper level of the liquid will not be parallel to the line. It will then suffice for the user to correct the position of the bag by verifying that the upper level of the liquid is parallel to the line, so to allow a correct dosage of the liquid.

In the embodiment illustrated in Figure 8 the first indication 3 is formed by two lines applied at the same height h on either side of the bag. Of course the first indication could also be formed by a single line. According to another embodiment, illustrated in Figure 6, a hole 33 is present at the first indication, which hole is then used as a first indication. This hole then constitutes an evacuation of the overflow of liquid and this will prevent filling the second container beyond the first indication.

Preferably, the second receptacle comprises, as illustrated in FIG. 3, a series of second indications 5, 6, 7 arranged according to a reading scale whose graduations represent in each case a fraction of said dose of liquid. It happens indeed, for example for repair work, that one does not need the entire volume of dry matter present in the first container. Since the dose of liquid indicated by the first indication 3 corresponds to that required for the whole (100%) volume of the dry matter, the presence of a series of second indications, which correspond to fractions (for example 25% , 50%, 75%) of this dose, will greatly facilitate the task of the user, who will use only a fraction of the material present in the first container. Where appropriate, and as illustrated in FIG. 7, these fractions may be volume indications, for example per half liter or deciliter, when, for example, the dose indicated on the first container is indicated in a volume of liquid, for example example 0.31 per kg. These second indications are also preferably formed by a line, as is the case for the first indication. These second indications can be applied either on a linear reading scale or a nonlinear reading scale. The reading scale can either take a full range of ticks, or a fraction of that range.

When the quantity of dry matter present in the first container is high, for example 25 kg or more, it may be envisaged that the first indication is placed at a height which corresponds to a fraction of the liquid dose for the total quantity of the liquid and it is accompanied by information taken from either the first or the second container indicating the number of doses to be added to the total dry matter. Thus in the example of 25kg of sand and cement mixture requiring 7.5 liters of water (0.31 / kg x 25kg = 7.51) to make the mortar the first indication could be placed at a volume of 2 , 51 which would then have to be filled three times. This has the advantage of not making the second container too large and to facilitate the transport of liquid from the source to the place where the pasty material will be applied.

The dosage of the liquid may depend on parameters such as, for example, the ambient temperature, the humidity present in the air where the pasty mixture will be used, or a tolerance indicated by the manufacturer of the dry matter. Thus for example when the ambient temperature is 15 ° C it will take less liquid than when it will be 25 ° C. To take account of these parameters, preferably said first indication 3 is accompanied by an auxiliary indication indicating a margin of tolerance for said volume of liquid. In particular this auxiliary indication may indicate a minimum volume and a maximum volume of the liquid to be added to the dry matter. This auxiliary indication is for example formed by at least two additional lines 3 'and 3 "placed on either side of the first indication 3, as illustrated in FIG. 4. Thus, for example, the first indicator 3 indicates the dose of liquid at a first temperature of 20 ° C, line 3 'at a second temperature of 15 ° C and line 3 "at a third temperature of 25 ° C. For better distinguishing line 3 from lines 3 'and 3 "it is for example possible to apply a thicker line for line 3 than for lines 3' and 3", or to use a dotted line for the indication 3 'and 3 "auxiliary and a solid line for the first indication 3. The auxiliary indication could also be applied as a mesh around the first indication.

Preferably, the width I of the bag corresponds to approximately half the height h at which the first indication 3 is applied. This embodiment has the advantage of promoting the accuracy of the dosing of the liquid in the second container. Indeed a width too large will result in the liquid surface at the height of the indication will be higher. A higher width results in a slight change in the height of the liquid immediately resulting in a higher volume difference and therefore a greater error in the dosage. Preferably the bag will have a width l = 20cm and the height of h at which the first indication 3 is applied, will be 40cm.
