EP3802351B1 - Packaging comprising a plastic container with constant stacking pitch - Google Patents

Description

The invention relates to a packaging comprising, on the one hand, a container, plastic, comprising side walls meeting in corners, an upper opening and a bottom, and on the other hand, a lid, plastic, detachable configured to cover the top opening of the container.

The field of the invention is that of the packaging of powdered products, in the food and/or pharmaceutical industry.

By way of non-limiting example, the powders concerned may be Sorbitol NEOSORB ^® , Maltitol SWEETPEARL ^® , Xylitol XYLISORB ^® , Mannitol PEARLITOL ^® etc. (...) marketed by the Applicant.

In this industry, it is customary to package these products in powder with unit volumes of between 40 liters and 60 liters. In the current state, these powders are packaged in packaging that includes a cardboard box body, typically a " kraft box " or more rarely a "kraft drum". The " kraft box " is essentially made up of a pre-cut and folded cardboard blank, with an automatic bottom, allowing the blank to be stored in a substantially flat position when not in use, and its expansion by unfolding the automatic bottom. By way of comparison, the kraft drum has the drawback of being more expensive, in particular due to the use of metal strapping, and of being bulky when not in use, namely that it cannot be folded flat when Not used. In both cases, the powdered product is placed inside the box body, inside a hermetically sealed flexible bag.

A first problem with these paper packagings is that they generate fibres, which represents a troublesome source of pollution for certain sensitive industries which would like to isolate this type of fibrous pollution.

These packages are also required to be transported, in containers, by ship, over long distances, and come into contact with insects. A second problem encountered is that of the non-sealing of the box body against insects, which can even develop in the cardboard embossing of the box body during the delivery time, with penetration of insects into the internal volume. Occasionally we find insects of the Thysanoptera type trapped in the inter-space between the flexible bag and the body of the box, inside the latter.

In such a case, these packaging are simply refused by the industries (pharmaceutical or food) because of the intruders, generating a dead loss for the manufacturer of the powdery products, which constitutes a second problem for this type of paper packaging.

A third problem with such paper packaging is their fragility, this being able to tear during impacts, or when they are subjected to excessive stress, for example when stacked, on top of each other. It is also important to point out that the packaging of such powdered products must not degrade the specificities of said powders which may have, as an important characteristic sought, for example a particular texture, a texture which must not be degraded during delivery in because of transport movements and friction generated on these powders.

However, we know from the document FR3005457 a package comprising, on the one hand, a container, plastic, comprising side walls meeting at corners, an upper opening and a bottom, and on the other hand, a lid, plastic, detachable configured to cover the upper opening of the container, and in which said container is provided at its upper opening with a first engagement portion bearing an outwardly directed ridge, and extending over the periphery, said lid being provided on its periphery with a second downwardly extending engaging portion provided with a ridge, and wherein said side walls of the container are diverging, forming a truncated pyramid therebetween, configured such that said container is stackable within an identical container, said container having projections extending from the side walls at the top opening of the container and below said first portion of engagement of the r container, said projecting parts being external to the container.

According to this prior art FR3005457 , the container is configured such that the bottom of the container can be introduced into a cavity of another container through the opening of the latter for stacking purposes,. To this end, each corner of the polygonal shape of the side walls of the container has a projection and a recess (in negative of the protrusion), wherein the protrusion extends away from the cavity for the purpose of acting as a spacer, thereby regulating the extent to which one container can be inserted into another container when stacking containers.

The recess is arranged opposite and corresponding to the respective projection, wherein the lid includes a locking element at each corner of the polygonal shape of the lid such that the locking elements are associated with respective recesses in the container , Each lid latch and the respective container recess are configured to engage with each other to releasably connect the lid to the container for the purpose of closing the cavity of the container.

The container and the lid include flanges corresponding to the respective perimeters thereof to be engaged with each other in order to allow the lid (and the container to be connected to each other using a seal to close the cavity of the container The lid is in a first orientation relative to the container when the flanges of the container and the lid engage with each other, wherein the lid is in a second orientation. orientation with respect to the container when the locking elements of the lid engage with the respective recesses of the container, wherein the lid in the first orientation is reversed compared to the lid in the second orientation

The object of the present invention is to overcome the aforementioned drawbacks by proposing a packaging offering effective protection against the intrusion of insects, the packaging not generating fibers, and at an acceptable cost for the manufacturer, and which is little bulky when storing the packaging when empty.

More particularly, the object of the present invention is to provide such packaging which does not attack the contents during the dynamic storage of the products inside the packaging.

Another object of the present invention is to provide such a packaging which can be opened easily, ie without tools.

Another object of the present invention is to provide such a packaging with easy opening (without tools), limiting accidental openings during impacts.

Another object of the present invention is to provide such a packaging, having an opening indicator suitable for signaling a fraudulent opening.

Another object of the present invention is to propose, at least according to one embodiment, a packaging which can be stacked, in particular on several levels, such as three superimposed packagings, or even four superimposed packagings.

Another object of the present invention is to provide such a packaging facilitating the control of the contents, and without requiring the contents to be removed, or even to remove the lid of the packaging.

Other advantages of the invention will appear during the description which will follow which is given only as an indication and which is not intended to limit it.

Also the invention relates to a packaging comprising, on the one hand, a container, plastic, comprising side walls meeting in the corners, an upper opening and a bottom, and on the other hand, a lid, plastic, detachable configured to cover the upper opening of the container, and wherein said container is provided at its upper opening with a first engagement portion bearing an outwardly directed ridge, and extending over the periphery, said lid being provided on its periphery a second downwardly extending engagement portion provided with an inwardly directed ridge which is capable of hooking below the outwardly directed ridge of the container ,
and wherein said side walls of the container are divergent, forming between them a truncated pyramid, configured so that said container is stackable inside an identical container.

According to the invention, said container has projections extending from the side walls at the level of the upper opening of the container and below said first engagement portion of the container, said projections being external to the container, configured to guarantee a constant stacking pitch between the container and said identical container, when said container is stacked in said identical container, said projecting parts being configured so as to cooperate in abutment with the upper edge of the upper opening of the identical container inside which said container is stacked in order to guarantee said stacking pitch.

De manière notable encore, lesdites parties saillantes sont agencées en saillie extérieure à partir des coins , au moins l'une des nervures extérieures s'étendant au niveau des coins, depuis son extrémité basse formant le plat jusqu'au bord supérieur du récipient, à son extrémité supérieure, à la hauteur de ladite section de jupe repliable lorsque l'arête dirigée vers l'intérieur est en position d'engagement avec l'arête du récipient dirigée vers l'extérieur .According to the invention, and furthermore:

• said protruding parts take the form of external ribs, extending vertically below said first engagement portion of the container, each external, vertical rib, presenting at its lower end a flat intended to cooperate in abutment with the upper edge of the upper opening of the identical container inside which said container is stacked,
• the second engagement portion of the lid has a skirt extending over the lower part of the second engagement portion and in which said edge of the container directed outwards, on the one hand, and the edge of the lid directed inwardly, on the other hand, having curved angle sections at the corners where said side walls meet, wherein at least one of the curved angle sections of the inwardly facing edge is provided with a section collapsible skirt hinged via a fold area at the top of the engagement portion which is able to fold from an engaged position to an outwardly directed unobstructed position such that a central portion of said at least one curved angle section of the inwardly facing ridge is leveraged away from the outwardly facing ridge of the upper opening and the engagement between the ridges is thereby weakened on said portion central ;

Also in a notable manner, said protruding parts are arranged projecting outwards from the corners, at least one of the outer ribs extending at the level of the corners, from its lower end forming the dish to the upper edge of the container, at its upper end, at the height of said collapsible skirt section when the inwardly directed edge is in the position of engagement with the outwardly directed edge of the container.

The height of the outer rib along the vertical defines the stacking pitch, said outer rib thus extending from the flat function of the abutment, at its lower end, to the upper edge of the container, at its upper end;

Advantageously, the vertical ribs then advantageously constitute obstacles limiting the risks of accidental opening of the folding skirt sections, by deflecting the unfortunate pressures of an object which would accidentally press under the skirt section.

The invention also relates to a packaging 1 comprising, on the one hand, a container 2, plastic, comprising side walls 20, 21, 22, 23 meeting in corners 24, an upper opening 25 and a bottom 26, and on the other hand, a lid 4, plastic, detachable configured to cover the upper opening of the container 2.

The plastic material used can be a polypropylene, or even polyethylene, of food quality, by way of non-limiting examples.

Said container 2 is provided at its upper opening 25 with a first engagement portion 34 carrying a ridge 27 directed outwards, and extending over the periphery, said lid being provided on its periphery with a second portion of engagement 40 extending folded downwards provided with a ridge 41, directed towards the interior which is capable of hooking below the ridge 27 directed towards the outside of the container.

The closing of the upper opening 25 of the container is obtained by positioning the second engagement portion 40 of the lid on the first engagement position 34 of the container, then by exerting a force on the lid so as to obtain a fitting between two engagement portions by elastic deformation of these portions (namely the first engagement portion, the second engagement portion or both), and until the edge 41 of the lid, directed inwards, passes below the edge 27 directed towards the outside of the container. Once the cover has been “ clipped ” in this way, the interior volume of the packaging is sealed off from insects in particular.

The side walls 20, 21, 22, 23 of the container 2 are divergent along the height, forming between them a truncated pyramid: these side walls 20, 21, 22, 23 are configured so that said container 2 is stackable at the inside an identical container. When not in use, and as shown in figure 1b for two containers packaging according to the invention, it is possible to stack one of the containers in the other.

Also notably, a constant marked stacking pitch Dep is provided between the two containers stacked one inside the other and so that the spacing between the side walls belonging to the two containers stacked one inside the other. the other is between 0.2 mm and 2 mm, and in particular between 0.3 mm and 1.2 mm. This spacing between the side walls is illustrated by way of example in figure 2b (with a value of 0.49 mm), and measures the distance separating two juxtaposed side walls belonging respectively to the two containers stacked one inside the other. Such a gap allows the operator to grasp and extract the upper container from the lower container, and without a suction cup effect, simplifying handling. This stacking pitch Dep measures the dimension according to the height separating two containers stacked one inside the other. This dimension is visible for the invention at the figure 8 and at the figure 13 and at the figure 6 for a container according to the state of the art.

THE figures 5 and 6 are views illustrating how the containers of the state of the art, stacked one inside the other, guarantee the presence of a stacking pitch by means of vertical ribs, projecting inwards. These vertical ribs with a stacking pitch function are marked N and extend from the bottom 26' over the lower part of the corners of the container. When the upper container is stacked in a lower container, the bottom 26' of the upper container comes into abutment against the flats at the end of the internal ribs of the lower container, guaranteeing the presence of a stacking pitch. The stacking pitch is configured so that the gap between two side walls is 0.8mm, as shown in figure 6 .

Notably, and according to this state of the art, the ribs are provided inside the container, and therefore protrude in the direction of the content. The invention arose from the observation by the inventor that these projecting ribs towards the content are incompatible with one of the objectives of the invention, which is intended not to deteriorate the properties of the product contained during dynamic storage.

For example and for a packaging of food or pharmaceutical powders, indirectly contained in a sealed flexible bag internal to said container of said packaging, such vertical ribs will create friction on the flexible bag during movements due to transport. This friction can lead to weak points in the flexible bag which can go as far as tearing it. Alternatively, and for the packaging of food or pharmaceutical powders, directly contained in the internal volume of the container of the packaging, such vertical ribs will create friction on the powder contained. This friction on the powder can cause a change in these properties, and in particular a modification in their texture.

The receptacle of the packaging in accordance with the invention advantageously does not have such internal ribs with a stacking pitch function. The interior surfaces of the container, including those of the bottom 26, the side walls 20, 21, 22, 23 and the corners 24 are preferably smooth, devoid of ribs or other protuberances likely to attack the contents.

The container according to the invention has projections 29 extending from the side walls at the level of the upper opening 25 of the container and below said first engagement portion 34 of the container, said projections 29 being significantly, and according to the invention, external to the container, and not internal as in the state of the aforementioned technique illustrated in figures 5 and 6 .

These projecting parts marked 29 are configured to guarantee a constant stacking pitch between the container 2 and the said identical container 2', when the said container is stacked in the said identical container, the said projecting parts 29 being configured so as to cooperate in abutment with the upper edge 30 of the upper opening 25 of the identical container inside which said container is stacked in order to guarantee said stacking pitch.

Said projections 29 take the form of outer ribs 31, extending vertically below said first engagement portion 34 of the container. Each outer rib 31, vertical, has at its lower end a flat 32 intended to cooperate in abutment with the upper edge 30 of the upper opening of the identical container inside which said container is stacked. Said projecting parts 29 are arranged projecting outwards from the corners 24. When the side walls 20, 21, 22, 23 are four in number, four projecting parts 29 can be provided projecting from the four corners 24 separating the side walls.

According to the present invention, the height of the outer rib 31 along the vertical defines the stacking pitch Dep, and as illustrated by way of example in the figures. The outer rib 31 extending from the dish 32, at its lower end, to the upper edge 30 of the container, at its upper end.

According to an embodiment understandable to the figure 14 , the first engagement portion 34 of the container carrying the said edge 27 of the container directed towards the outside extends folded downwards, covering the side walls 20, 21, 22, 23 and the corners 24 on an upper part of the height of the container, with the presence of a peripheral Int cavity in the interspace. This cavity, which extends around the periphery of the container, is delimited between the outer surface of the side walls 20, 21, 22, 23 and of the corners 24, on the one hand, and the folded section of the engagement portion 34, on the other hand.

We also note the presence of vertical reinforcing ribs 35, distributed in said cavity on the periphery of the container, each reinforcing rib 35 connecting one of the side walls 20, 21, 22, 23 or corner 24, on the one hand , to said folded section of the first engagement portion 34, on the other hand, and as visible in figure 12 . Each rib projects substantially perpendicular to the wall forming the corner or to the wall forming the side wall.

According to one embodiment, it is noted that the outer ribs 31 guaranteeing the constant stacking pitch each extend from their lower end forming the flat 32, located below the cavity Int and said first engagement portion 34 of the container and to the inside of said cavity Int where said vertical outer rib 31 extends forming one of the reinforcing ribs 37. In such a case, the rib outer 31 combines a dual function, namely a function for achieving the stacking step and a reinforcing rib function 37, in particular connecting the corner 24 and the folded section of the first engagement portion 34.

According to the invention and as visible on figure 7 , the second engagement portion 40 of the lid has a skirt 42 extending over the lower part of the second engagement portion 40 and in which said edge 27 of the container directed towards the outside, on the one hand, and the inwardly directed edge 41 of the lid, on the other hand, having curved angle sections 28, 43 in the corners 24 where said side walls 20, 21, 22, 23 meet, where at least one of the sections curved angles of the inwardly facing ridge 41 is provided with a collapsible skirt section 44, hinged via a folding area 46 to the top of the second engagement portion 40 of the lid.

This collapsible skirt 44 is able to fold from an engaged position to a disengaged position directed outwards so that a central part of said at least one curved angle section of the ridge 41 directed inwards is removed by lever effect of the edge 27 directed towards the outside of the upper opening 29 and that the engagement between the edges 27,41 is thus weakened on said central part. The passage of the folding skirt 44 from the engaged position to the disengaged position can be carried out manually, facilitating the removal of the cover which can be carried out without tools.

According to one embodiment, said folding skirt section 44 is separated from the remaining section of the skirt 42 by means of two grooves 45 formed in the outer surface of the skirt 42 and extending downward from a folding zone 46 to the lower edge of the skirt 42, said grooves 45 reducing the wall thickness of the skirt 42 so that the skirt can be broken along the grooves 45 to collapse the collapsible skirt section 44 into its directed position outwards. The lid 4 may have four folding skirt sections at the four corners of the lid, when the container has four side walls. For the realization of such folding sections 44, the person skilled in the art can for example refer to the document EP 1.380.516 A1 .

According to the invention, at least one of the outer ribs 31 extends at the level of the corners 24, from its lower end forming the flat 32 and at least up to the height of the said folding skirt section 44 when the edge 41 directed inwards is in the position of engagement with the edge 27 of the container 2 directed outwards. For example, and as seen in figure 13 by way of example, said outer rib 31 vertically to the right of the folding skirt section 44 is, in a horizontal direction passing through the plane of the outer rib 31, of increasing dimension between its lower end forming the flat 32 and the lower end 48 of the collapsible skirt section 44.

For example, and at the figure 13 it will be noted that said outer rib 31 forms a ramp 33 diverging outwards when approaching, from the flat 32 of the lower end of the outer rib 31 towards the lower end 48 of the skirt section collapsible 44 then in the engagement position. The position of the outer rib 31, vertical, near and below the folding skirt section 44, or even the ramp 33 thus created, advantageously constitutes an obstacle limiting the risks of accidental opening of the folding skirt sections 44, by an unfortunate support of an object which would come accidentally, during an uncontrolled handling, under the skirt section 44. at the four corners of the container extend respectively in line with the four skirt sections 44. Each of the vertical ribs 31 then extends at the level of the corners 24, from its lower end forming the flat 32 and at least up to the height of said collapsible skirt section 44 when the inwardly directed ridge 41 is in the position of engagement with the outwardly directed ridge 27 of the container 2. Each rib then constitutes an obstacle limiting the risks of accidental opening of the folding skirt sections 44, by preventing unwanted support under the folding skirt.

• la première portion d'engagement 34 du récipient portant l'arête 27 dirigée vers l'extérieur s'étend et se prolonge en dessous de ladite arête 27, dite première arête, et se termine en dessous de ladite première arête par une seconde arête 35 également dirigée vers l'extérieur,
• la section de jupe repliable 44 portant l'arête 41 dirigée vers l'intérieur à même de s'accrocher avec la première arête 27 porte, dans la position d'engagement de la section de jupe repliable 44, une seconde arête 47 dirigée vers l'intérieur, à même de s'accrocher avec la seconde arête 35 dirigée vers l'extérieur de la première portion d'engagement 34.

According to one embodiment, and as visible by way of non-limiting example according to figure 13 :

• the first engagement portion 34 of the container carrying the edge 27 facing outwards extends and extends below said edge 27, called the first edge, and ends below said first edge with a second edge 35 also directed outwards,
• the collapsible skirt section 44 carrying the inwardly directed ridge 41 capable of hooking with the first ridge 27 carries, in the engagement position of the foldable skirt section 44, a second ridge 47 directed inwards inside, able to hook with the second edge 35 directed towards the outside of the first engagement portion 34.

The possible presence of a double edge 41 and 47 makes it possible to increase the hold of the second engagement portion 40 of the cover 4 on the first engagement portion 34 of the container.

Increasing the hold of the lid on the container can be advantageous in many respects, and in particular to allow manipulation and lifting of the packaging by means of a suction cup lifting device engaging the lid of the packaging , in its center, the connection between the lid and the container having to be strong enough to support the weight of the packaging and its contents when said packaging is suspended by its lid. According to one embodiment, the container has a useful capacity of between 40 liters and 60 liters. In the case of packaging with a capacity of 40 liters to 60 liters, the density of the powders often being between 0.3 and 0.6, it is understood that the connection between the lid and the container must be able to lift a weight of the order of 20 kg to 30 kg to allow manipulation by suction cup.

According to one embodiment, two handles 36 extend, along the height of the container, each handle 36 being positioned below the engagement portion 34 of the container and above or level with the lower ends with abutment function of the projecting parts 29 guaranteeing the constant stacking pitch, said handles 36 projecting laterally from two opposite side walls 21,23 of the container.

• la dimension d1 étant la dimension hors tout de l'emballage suivant une première direction horizontale passant par les deux poignées et constituée par la distance séparant les deux poignées 36,
• la dimension d2 étant la dimension hors tout d2 suivant une direction horizontale perpendiculaire à la première direction horizontale et dans lequel 0,95 d1 < d2 < 1,05 d1.

According to one comprehensible embodiment of the figures 1b and 2b , the side walls 20, 21, 22, 23 are four in number, namely a container of rectangular section and in particular:

• the dimension d1 being the overall dimension of the packaging along a first horizontal direction passing through the two handles and consisting of the distance separating the two handles 36,
• the dimension d2 being the overall dimension d2 along a horizontal direction perpendicular to the first horizontal direction and in which 0.95 d1 < d2 < 1.05 d1.

For example and at the figure 2b , the dimension d1 is 386 mm and in figure d2 the dimension is 387 mm, namely a substantially identical dimension. Providing an identical or almost identical overall dimension in both directions makes it possible to place nine packages side by side on a 1140 mm × 1140 mm pallet, distributed along three columns and three rows, in a 3×3 configuration, optimizing capacity of the pallet.

In general, dimension d1 and dimension d2 can be between 380 mm and 390 mm. The height of the container from the bottom to the upper edge of the first engagement part 34 can be between 450 mm and 550 mm and for example 517.7 mm as illustrated in figure 1b .

According to one embodiment, the thickness dimension of the side walls 20, 21, 22, 23 is between 2 mm and 2.2 mm, such as 2.1 mm, the container being capable of withstanding a compressive force of between 40 kilograms and 105 kilograms, and preferably 75 kilograms applied to the lid 4 in the engagement position on the upper opening of the container.

This makes it possible to stack three or even four packages (with the products contained) on top of each other. For example, the figure 4 is a perspective view of a packaging comprising a 1140 mm × 1140 mm pallet on which rest four beds of packaging stacked on top of each other, each bed being made up of 9 packages distributed side by side in a square configuration (3 × 3), using a 1140 mm × 1140 mm pallet, intermediate between the second bed and the third bed.

According to an advantageous embodiment, the wall of the lid 4 has a pre-cut opening closed by a breakable shutter 5. A breakable line 50, formed by a reduction in section of the cover wall 4 defines the outline of the shutter 5 and of said pre-cut opening, said breakable line 50 being configured so that manual pressure on the shutter 5 ensures the break of the break line 50, and thus the release of the pre-cut opening.

It is thus possible to retract the shutter 5 by a simple manual pressure on it. The opening thus freed allows the introduction of an analysis probe, such as an analysis probe of a Raman spectrometer.

According to an advantageous embodiment, it is noted that said divisible line 50 extends around the periphery of shutter 5 with the exception of a zone intended to constitute a retaining tab 51 of shutter 5, once said line breakable 50 sectioned. This breakable line 50 is thus configured so that a manual pressure on the shutter ensures the breaking of the breakable line 50 and thus the release of the pre-cut opening, then the maintenance of the shutter 5 under the wall of the cover 4 via said retaining tab 51, flexible.

Note that the position of this pre-cut opening (with its breakable shutter) is not determined by chance, the latter being positioned at a distance from the corner areas of the lid where the base of a container of a package stacked on the cover of the package: this prevents the action of the weight of a package on the cover from cutting the breakable line 50, and accidentally opening the opening. Similarly, note that the pre-cut opening is at a distance from the center of the lid: this prevents the press used to put the lid on the container from cutting the breakable line, or even the suction cup of a device for lifting used to lift the package and its contents by suction cup effect in the center of the lid does not weaken or even cut said breakable line.

We also note that the disc forming the shutter can be embossed with a visual indicating the zone of the shutter on which it is necessary to press to release the pre-cut opening.

Also, the cover 4 being substantially rectangular in shape comprising four corners 49, and as illustrated in figure 9 , it is noted that the pre-cut opening and the shutter 5 are located on the lid at a distance from the corners 49 on an axis of symmetry A of the lid, and in an off-center position with respect to the center C of the lid.

The container 2 and said cover 4 can be obtained, typically by injection molding. In such a case, the die and the punch will make it possible to obtain the various characteristics of the packaging during the molding, such as the external, vertical ribs with a stacking step function, the dividable folding skirt sections, the opening pre-cut with its breakable shutter, allowing the realization of a packaging at a lower cost. Note also that the retaining tab 51 is positioned on the side of the shutter 5 facing the direction opposite to the center of the lid. This allows the insertion of the probe, through the opening, and while the shutter is held by the retaining tab 51, in a position where the probe can be tilted towards the center of the container, and without the retaining tab and the maintained shutter do not oppose such an inclination.

The packaging in accordance with the invention finds a particular application for the packaging of food or pharmaceutical powders, directly contained in the internal volume of the container of the packaging, or indirectly contained in a flexible sealed bag internal to said container of said packaging.

• une étape a) d'insertion du produit en poudre dans une sache souple, par une ouverture supérieure de la sache,
• une étape b) de fermeture étanche de l'ouverture supérieure de la sache souple, par exemple par thermo soudure ou encore soudage par ultrason de la sache souple,
• une étape c) d'insertion de la sache souple remplie (voire fermée de manière étanche) dans le volume intérieur du récipient, par son ouverture supérieure 25,
• une étape d) de positionnement du couvercle de l'emballage sur l'ouverture supérieure du conteneur,
• une étape e) de mise en place du couvercle, par une pression exercée sur le couvercle afin que la première portion d'engagement 34 du récipient 2 s'emboîte avec la deuxième portion d'engagement du couvercle, et jusqu'à ce que ladite arête 41 dirigée vers l'intérieur du couvercle passe en dessous et s'accroche avec ladite arête 27 du récipient.

The packaging process for the powdered product may include the following steps:

• a step a) of inserting the powdered product into a flexible bag, through an upper opening of the bag,
• a step b) of sealing the upper opening of the flexible bag, for example by heat welding or even ultrasonic welding of the flexible bag,
• a step c) of inserting the filled flexible bag (or even sealed) into the interior volume of the container, through its upper opening 25,
• a step d) of positioning the lid of the packaging on the upper opening of the container,
• a step e) of fitting the lid, by pressing on the lid so that the first engagement portion 34 of the container 2 engages with the second engagement portion of the lid, and until said edge 41 directed towards the inside of the cover passes below and hooks with said edge 27 of the container.

Alternatively, the flexible bag can be inserted empty into the container of the packaging, step a) of inserting the powdered product and step b) of closing then being carried out while the flexible bag is already positioned in the container, and before fitting the lid.

Step e) of fitting the lid can be carried out by means of a jack, ensuring at the start of the race a slight pressure on the lid in order to allow a pre-fitting of the lid on the container (of the first portion of engagement 34 of the container with the second engagement portion 40 of the lid), and at the end of the race a much higher pressure ensuring the grip of the edges 27 and 41 between them, or even of the edges 35 and 47.
