Description

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of packaging and more particularly the field of packaging intended to contain a substance whose restitution is obtained by pressure exerted manually on the packaging and / or by gravity. It finds for particularly advantageous application the agro-food, industrial, cosmetic, domestic, pharmacological and health sectors in general.

STATE OF THE ART

In the field of pastry, for example, in order to deposit or pour pastry cream, the use of pastry bag is common. A socket pocket consists of a conical pocket having two ends of different sections. The largest end is not closed but open. Devices of this type have drawbacks related to their poor restitution, the absence of a cap and therefore the need to use the content in its entirety at the risk of significant waste. In addition, once open, the socket bags do not retain their form by themselves and can not be rested on a work plan without seeing their contents spill. However, the use of a piping bag allows very good handling, a precise touch and therefore a significant "product" sensation, very good control of the doses delivered and a very good return of the product.

It is called restitution the ratio between the amount of product initially contained in the socket bag and the content inevitably remaining at the end of use. Thus, a good restitution implies a great ability to extract all the contents of the container.

In order to solve the disadvantages mentioned above, the field of packaging also uses bottles or bottles formed of a continuous external envelope in a plastic-type material but also tubes. These packs have a better vertical retention than a piping bag. They usually have a cap to close the packaging. Finally, they allow an easy deposit of the content. However, this type of packaging has a very low return of the product. Indeed, at the end of use, there remains a significant amount of product that can not be extracted. Moreover, they are not pleasant to the touch.

WO 2012/017938 A1 and US 2005/0265636 A1 disclose packages comprising a pouch for containing a product and allowing its recovery, and comprising: a manually deformable envelope, the first film being closed on itself so as to form a trunk having a first and a second end, the section of the trunk narrowing as it approaches the first end; a base formed of a second film and sealed to the second end of the trunk so as to close the second end, the base and the envelope being sealed flesh against flesh to form together a manually deformable pocket; a closure device through which the product is intended to flow during the restitution.

An object of the present invention is therefore to provide a device that solves at least some of the aforementioned drawbacks.

SUMMARY OF THE INVENTION

According to an optional embodiment, but particularly advantageous, the base and the envelope are sealed "flesh against flesh" to form together a manually deformable bag;
• a closure device through which the product is intended to flow during the recovery and comprising a socket sealed to the first end of the trunk.

This device allows a very good handling and a touch, a sensation "product" very important. Indeed, it has the advantage of the sleeve pocket, namely a flexible body, deformable by a simple pressure exerted manually by the user with one or two hands. The flexibility of the pocket allows a very good return of the product and improves the control of the pressure exerted. This level of control allows a very precise distribution of doses. Finally, this pocket has an improved vertical support, sleeve upwards, by the cooperation of the flexible envelope with the flexible base. Indeed, the envelope / base seal provides mechanical reinforcement of the pocket. This seal has a thickness which is the sum of the thicknesses of the envelope and the base. In addition, depending on the type of accessory used at the socket, the device can be held vertically, socket down. This advantageous position facilitates the flow of the product inside the flexible bag.

It will be noted that the relative characteristics stated above, in particular those relating to the flexibility of the packaging, to its capacity to be deformed, to the types of seals, to the flow channels and to the shape of the base, although advantageously operating in synergy when combined, can be exploited independently of each other and still confer certain technical advantages. The invention thus describes packages which have only one or a combination of some of the features mentioned above.

According to a possible embodiment and serving as a non-limiting example presented by the figures 1 , 2 , 3 , 4 , 5 , 6 and 7 , the present invention 1 comprises a flexible envelope 201. This envelope 201 consists of a film. This film is closed on itself. This film, once closed on itself, forms a trunk. In the context of this invention a trunk may have a section of any shape without being limited to a circular section. This trunk has a first and a second end. The section of this trunk thus formed narrows as it approaches the first end.

This trunk is made by sealing "skin against flesh" of the film over a width of the envelope of between 1 and 20 mm and preferably between 1 and 5 mm and preferably equal to 5 mm. This type of sealing allows a better grip of the device by a user, as well as a more homogeneous deformation.

The film is preferably a multilayer film.

A base 202 is sealed to the envelope 201. The envelope 201 and the base 202 are sealed by a seal 400 of the "flesh-against-flesh" type. This seal 400 is performed at the second end. Thus the envelope 201 and the base 202 form a pocket 200. The base 202 is made of a flexible material. This flexible material may for example be of the same nature as the material of the envelope 201 and preferably a flexible film monolayer or multilayer and preferably OPP / OPA / ALU / PE or OPP / metallized polyester / PE.

The present invention comprises a closure device 100. This closure device 100 is sealed at the first end of the envelope 201, the one of smaller section. The closure device 100 may, for example, comprise a sleeve 102. Preferably, the sleeve 102 is more rigid than the envelope 201. This sleeve 102 may, according to one embodiment, have a thread 105 on its external face which is not in contact with the product contained in the bag 200. This thread 105 can be used to adapt an accessory 101 of the closure device 100. The accessory 101 can be a plug (capsule, pump, etc.). .) or a support having silicone lips 104 having a lid 106 for example.

This device 1 thus produced has a very good stability in the vertical position, socket 102 upwards and therefore resting on the envelope / base 400 seal. In fact, this seal 400 is a seal of the "flesh against flesh" type. This seal therefore has a greater rigidity since its thickness is the sum of that of the casing 201 and that of the base 202. This stability is acquired that the device 1 is full or empty or partly full.

This device 1 also has the advantage of a small footprint once empty, its pocket 200 being flexible. It is possible to compress the bag 200, open cap and keep this shape if the cap is closed before stopping the pressure stresses exerted on the bag 200.

Finally, according to one embodiment, if the stopper remains open after the cessation of the pressure stresses, the device 1 resumes its original shape allowing vertical retention sleeve 102 upwards.

According to another embodiment, after the stop of the pressure stresses, and independently of the state of the plug, the device 1 keeps its deformed shape. This has the advantage, for example, to preserve the product remained in the flexible pouch of any contact with the surrounding air.

According to another embodiment, if the plug remains open after the cessation of the pressure stresses, the device 1 partially takes its original form.

The fact that the present invention has a deformable pocket 200 allows a better reproduction of the product contained therein. To facilitate this restitution and the maneuverability and accuracy of use of this device 1, the flexible bag 200 has an improved deformation capacity allowing its deformation to a hand for a user of standard force.

The base 202 of the present invention has any geometry, preferably polygonal, preferably polygonal with rounded corners, and preferably diamond-shaped with rounded corners. The geometry of the base 202 is adapted to cooperate with the envelope 201 so that the latter matches the shape of the contour of the base 202. At each angle, preferably rounded, formed by the base 202, the envelope 201 forms a channel said flow channel 500 which extends from the base 202 and towards the sleeve 102. The flow channels 500 are thus formed inside the pocket 200 in the presence and / or in the absence of pressure exerted by a user of standard force. The preferentially polygonal geometry with rounded angles, and advantageously a diamond geometry with rounded angles, makes it possible to form flow channels 500 which promote the aggregation of the product contained in the pocket 200 at the rounded corners in the absence and / or in the presence of external pressure. These aggregates of material locally increase the value of the ratio mass of material to be extracted on the contact surface between the material to be extracted and the inner wall of the envelope 200. This increase promotes the descent of the material towards the outside of the pocket 200 In the absence of pressure exerted, and depending on the viscosity of the content under consideration, the gravity may be sufficient to achieve these aggregates of material and thus to promote their flow along these channels 500 flow.

The present invention has a ratio between the perimeter of the sleeve 102 and the perimeter of the base 202 may vary between 0.001 and 1, preferably between 0.2 and 0.7 and preferably between 0.4 and 0.5. The present invention comprises a ratio between the height 401 of the envelope / base seal and the height 2 of the device may vary between 0.001 and 0.1, preferably between 0.001 and 0.05. Finally, the present invention comprises a ratio between the height 301 of the envelope / sleeve seal and the height 2 of the device that can vary between 0.001 and 0.2, preferably between 0.1 and 0.15.

These dimensions make it possible to improve the stability of the device 1 while offering good capacity. In addition, the solid angle thus formed by the flexible pouch 200 allows a good flow of the product contained in the flexible pouch 200.

• La figure 1a montre une vue en perspective du dispositif 1. Un couvercle 106 venant fermer l'accessoire 101 est positionné sur la douille 102 du dispositif 1. La poche 200 est maintenue à la verticale par le scellage enveloppe/embase 400. Ce scellage 400 est un scellage « chair contre chair ». Ce scellage 400 est plus rigide que l'enveloppe 201 puisque l'épaisseur de ce scellage 400 vaut la somme de l'épaisseur de l'enveloppe 201 et de celle de l'embase 202. Une épaisseur plus importante permet une plus grande rigidité. Cette rigidité est localisée sur le contour de l'embase 202. Ce contour plus rigide permet un meilleur maintien, à la verticale, du présent dispositif 1.
• La figure 1b montre une vue en perspective du dispositif 1. Un couvercle 106 venant fermer l'accessoire 101 est positionné sur la douille 102 du dispositif 1. La poche 200 est maintenue à la verticale par l'accessoire 101, douille 102 vers le bas. Dans cette position, le dispositif 1 permet au produit qu'il contient de descendre vers la douille 102 par simple gravité, de sorte que la restitution du produit est facilitée lors de la prochaine utilisation.
• Les figures 1a et 1b laissent apparaître la zone de scellage 205 peau contre chair de l'enveloppe pour que cette dernière conserve sa forme de tronc lorsqu'elle est repliée sur elle-même. Le trait en pointillé 206 illustre l'extrémité de l'enveloppe située à l'intérieur du tronc et dont la face externe est au contact de la face interne de l'extrémité située à l'extérieur du tronc.
• La figure 2 montre une vue en perspective du dispositif 1 en l'absence du couvercle 106. Selon un mode de réalisation possible, des lèvres en silicone 104 font partie de l'accessoire 101 positionné sur la douille 102 du dispositif 1. La poche 200 est maintenue à la verticale par le scellage enveloppe/embase 400 plus rigide que l'enveloppe.
• La figure 3 montre une vue de dessous du dispositif 1. Selon un mode de réalisation possible, l'embase 202 de la poche 200 a une forme de losange arrondi. Il a été également marqué à titre d'exemple non limitatif la position relative de quatre canaux d'écoulement 500 suivant ce mode de réalisation. Ces canaux d'écoulement 500 sont localisés proche des angles arrondis de la forme géométrique de l'embase 202.

An example of a device according to the invention will be described in more detail with reference to the figures.

• The figure 1a shows a perspective view of the device 1. A lid 106 that closes the accessory 101 is positioned on the socket 102 of the device 1. The bag 200 is held vertically by the envelope / base seal 400. This seal 400 is a seal "Flesh against flesh". This seal 400 is more rigid than the envelope 201 since the thickness of this seal 400 is the sum of the thickness of the casing 201 and that of the base 202. A greater thickness allows greater rigidity. This rigidity is located on the contour of the base 202. This more rigid contour allows a better maintenance, vertically, of the present device 1.
• The figure 1b shows a perspective view of the device 1. A lid 106 which closes the accessory 101 is positioned on the sleeve 102 of the device 1. The pocket 200 is held vertically by the accessory 101, sleeve 102 downwards. In this position, the device 1 allows the product it contains to descend to the sleeve 102 by simple gravity, so that the return of the product is facilitated during the next use.
• The figures 1a and 1b reveal the skin seal area 205 against flesh of the shell so that the latter retains its trunk shape when folded on itself. The dotted line 206 illustrates the end of the envelope located inside the trunk and whose outer face is in contact with the inner face of the end located outside the trunk.
• The figure 2 shows a perspective view of the device 1 in the absence of the cover 106. According to one possible embodiment, the silicone lips 104 are part of the accessory 101 positioned on the sleeve 102 of the device 1. The pocket 200 is maintained at the vertical by sealing envelope / base 400 more rigid than the envelope.
• The figure 3 shows a bottom view of the device 1. According to a possible embodiment, the base 202 of the pocket 200 has a rounded diamond shape. He has The relative position of four flow channels 500 according to this embodiment is also indicated by way of nonlimiting example. These flow channels 500 are located near the rounded corners of the geometric shape of the base 202.

In the vertical position, bushing 102 upwards, the entire contents or product will descend towards the base 202 of the pocket 200. However, the geometry of the base 202 associated with the envelope 201 to form the pocket 200 will allow the creation of flow channels 500 inside the device 1. Indeed, according to this embodiment, the diamond geometry rounded corners of the base 202 allows in the presence and / or absence of pressure exerted by a user of standard force on the pocket 200, socket 102 down and cover 106 removed, to lower the product contained in the pocket 200. Preferably, the geometry of the pocket 200 imposes preferred flow channels 500 thus making the easier flow. Similarly, these preferred flow channels 500 reduce the intensity of the pressure required to empty the product of the bag 200. The return of the product is thus facilitated. In addition, with a reduction in effort, the user then gains maneuverability, accuracy and management of the delivered dose.

The figure 4 and 5 show two cross-sectional views of the device 1 in the absence of the cover 106: respectively front and side. Silicone lips 104 are part of the accessory 101 positioned on the sleeve 102 of the device 1 by a threading system 105. The sleeve 102 is sealed to the envelope. The pocket 200 is held vertically by the envelope / base seal 400 in the shape of a rounded diamond. The base 202 of the device 1 is sealed to the casing 201 by a seal of the "flesh against flesh" type. The base 202 and the envelope 201 are, according to one embodiment, made of the same material and preferably from an identical film, for a question of ease of manufacture, aesthetics and maneuverability. The sealing of the base 202 with the casing 201 makes it possible to reinforce the rigidity of the seal. Furthermore, the base 202 extends in a plane substantially perpendicular to the walls of the casing 201 which maintains the shape of the casing at the level and reinforces the rigidity of the assembly. This reinforcement of rigidity allows the stable retention of the device 1 sleeve 102 upwards independently of the amount of product contained in the device 1. Note also the dimensions 401 and 301 which correspond respectively to the height of the sealing envelope / base in the direction longitudinal and the height of the envelope / sleeve sealing in the longitudinal direction. Similarly, the height 2 of the device 1 in the longitudinal direction is shown in these two figures.

The figure 6 shows a profile sectional view of the device 1 deformed in the presence of the cover 106. The pocket 200 is deformed. As a result, the base 202 and the casing / base seal 400 of the "flesh against flesh" type are also deformed. In particular, the pocket is configured so that the base 202 is crumpled or compressed. Finally, the "skin against flesh" seal 205 of the envelope 201 is also deformed. The figure 6 represents a deformation of the present device illustrating the ability of the entire pocket 200 to deform. This deformation typically results from compression exerted by the user with only one of these hands or with both hands. The rigidity of the closure device, and in particular of the sleeve, do not allow this deformation and this reduction of volume under the effect of the manual stress exerted by the user. Typically, the closure device and in particular the sleeve are made of a rigid plastic such as polypropylene, high density polyethylene (HDPE), polyvinyl chloride (PVC), etc ...

The figure 7 shows a perspective view of the deformed device 1. According to a possible embodiment, a cover 106 closes the accessory 101 positioned on the sleeve 102 of the device 1. The pocket 200 is deformed. The deformation is visible at the base 202. The deformation is visible at the level of the envelope / base seal 400. Finally the deformation is visible at the envelope / envelope seal 205.

The figures 6 and 7 thus illustrate a deformation of the pocket 200 showing that the entire bag 200 is deformable including the seals 205, 400 and the base 202. This ability to be deformed gives the bag 200 a great maneuverability and allows a very good return of the product.

According to one embodiment, the pocket 200 has an increased capacity of deformation which makes it possible to reduce the volume of the pocket 200 by at least one third, preferably by at least half and advantageously by more than half of its volume. volume when the device 1 is not deformed. This ability to reduce the volume of the bag 200 by exerting a pressure ensures a very good restitution of the product contained in the bag 200. The bag 200 is configured so that these volume reductions are obtained by manual pressure exerted by the user using two and preferably using only one of his hands.

According to one embodiment, the casing 201 and the base 202 are sufficiently flexible so that under the effect of a manual pressure exerted on the casing 201, two points arranged symmetrically with respect to a longitudinal axis to the packaging are placed in touch. This allows for example to aggregate effectively distributed product on the internal surfaces of the envelope. When the surfaces come into contact, the product distributed on these surfaces is aggregated and it is then easier to lower it towards the closing device.

Preferably, the envelope 201 and the base 202 are configured so that the pocket 200 can be twisted around an axis passing through the base and the sleeve, under the effect of a manual action of the user, the sleeve 102 remaining stationary. Typically, the user holds the sleeve 102 with one of his hands and twists the base 202 with his other hand. Advantageously, the envelope 201 and the base 202 are configured so that the envelope 201 and / or the base 202 can be twisted by at least 360 ° about an axis passing through the base 202 and the sleeve 102, under the effect of a manual action of the user. This structural configuration therefore allows a better return of the product, better handling and therefore increased deposit accuracy.

A particularly advantageous feature relates to the formation of flow channels 500 within the package 1 by the judicious choice of the geometry of the base 202.

In the case where there is no solicitation of the packaging 1 by a user, that is to say if the package 1 is placed sleeve 102 upwards, then only the gravity has an effect on the contents of the packaging 1. The geometric shape of the base 202 is adapted to cooperate with the casing 201 so as to form flow channels 500. In this situation, the flow is towards the bottom of the package 1, there is aggregation of material at the level of the flow channels 500, the mass of material increases while the contact surface of the material with the inner walls of the packaging 1 remains the same, thus creating a local increase in the flow which is a function of the viscosity of the content.

In the case where there is solicitation of the packaging by a user, the bag 200 of the package 1 being flexible, the user can then exert pressure on the bag 200 so as to extract its contents if the opening at the sleeve 102 sealed is free. The pressure exerted by the user brings the adjacent surfaces closer to the pocket 200. This approximation of the adjacent surfaces allows local aggregation of the product. This allows a routing of the channels 500 much more pronounced under the effect of the deformation. Thus, locally the aggregation of material increases and allows a better flow of the product, this accentuating the effect of 500 flow channels. This method then allows a better recovery especially for viscous fluids.

Advantageously and by way of nonlimiting example, the use of a geometry of the base 202 of the diamond type with rounded corners as illustrated in FIG. figure 3 makes it possible to form flow channels 500 which are naturally located at the rounded corners. It should be noted that the position of these flow channels 500 is related to the stress on the packaging 1 of the present invention and the geometry of its base 202 and / or its envelope 201.

In addition, the general shape of the rhombus makes it possible, by pressing on two opposite angles and bringing them together, for example by exerting on them two opposing forces with the fingers of the same hand, to reduce the other two angles of the rhombus. The surfaces adjacent to these two other angles then approach each other in pairs, or even until they come into contact. This effectively aggregates the product distributed on these surfaces. This embodiment thus makes it possible to improve the return of the product. An envelope of circular section would not allow approximation of surfaces.

A second particularly advantageous feature relates to the type of seal made at the level of the envelope 201. Indeed, a seal 205 of the "skin against flesh" type to form the casing 201 allows many advantages both functional and aesthetic. This type of sealing compared to "skin-to-skin" or "flesh-to-skin" seals does not leave a fin on the inside or outside of the device. The fins have many disadvantages, for example the outer fins from a "flesh-to-flesh" seal leave on the surface of the package a strip of protruding material and stiffer than the rest of the package. This strip of material is not pleasant when taken in hand. Moreover, it reduces the return of the product because it forms a rib opposing the deformation of the envelope. The deformation then caused by the user is reduced. In the case of a "skin-on-skin" seal, the fin is inside the packaging, the handling is not hindered but the angles formed by this inner fin has a resistance to the deformation of the packaging and prevents a good return of the product.

Conversely, the use of a "skin against flesh" seal does not form a fin, neither internal nor external. With this type of sealing, the packaging 1 is much more homogeneous to the touch and the sight. Moreover concerning the handling and deformation of a packaging of this type, the "skin against flesh" seal ensures an improved deformation of the entire envelope 201 in comparison with other types of sealing which by the presence of fins, inevitably forming the ribs, decreases its amplitude of deformation. The seal "skin against flesh" thus offers a greater amplitude of deformation and thus of compression, it shows an improvement in the return of the product, the handling of the packaging, the comfort of use and therefore the accuracy of deposit.

The invention is particularly advantageous for the agro-food sector with for example the use of chocolate paste as a substance to contain. It is also particularly advantageous for the industrial, cosmetic, domestic and health sectors.

The invention is not limited to the previously described embodiments and extends to all the embodiments covered by the claims.

According to one embodiment, the present invention also relates to a method of manufacturing at least one packaging according to the invention.

The figure 8 presents the different steps of the method according to an embodiment as well as the industrial apparatus for its realization. This method comprises a first step of cutting the pattern of the envelope in a film. This film, preferably multilayer, comes from a roll. This roll is unrolled by the cutting machine 1000. Next, the device 2000 manipulates the pattern of the envelope and closes it on itself to give it a trunk shape. This manipulator is able to cooperate with the sealing device 3000.

The device 3000 comprises a heating device adapted to come into contact with the inner face and the outer face of the envelope. At this stage of the process, the envelope is kept closed on itself forming a trunk. In this configuration the heating device performs a "skin against flesh" seal of the envelope. This sealing is performed in the longitudinal direction of the envelope. This sealing is performed along the entire length of the envelope in its longitudinal direction. This sealing thus forms the zone 205 illustrated in the preceding figures. This sealing is carried out over a width of the envelope of between 1 and 20 mm and preferably between 1 and 5 mm and advantageously equal to 5 mm.

Then a trunk loading manipulator 4000 positions said trunk on a sealing station 6000. This sealing station receives on the one hand the trunks and sockets. Sockets are provided by the device 5000. At the sealing station 6000, the sockets are sealed at the lower section of the trunk. Then Station 7000 transfers envelopes sealed by a socket to station 10000 for formatting and sealing the base and the envelope. The station 8000 carries out the shaping of the envelope with a view to its sealing with the base. The bases are cut in a film whose material is preferentially identical to that of the envelope. Station 9000 cuts the bases from a roll of film. Once at station 10000, the bases are sealed on the part of the trunk having the largest section. This seal is a "flesh-to-flesh" seal. This seal has a height in the longitudinal direction of the envelope between 1 and 20 mm and preferably between 1 and 10 mm and preferably equal to 10 mm.

Finally and optionally, the device 11000 performs a leak test of the newly formed bag. Then, a 12000 manipulator places the pockets on a 13000 cumulative ribbon of finished parts.

As regards the filling of the present device, there are several embodiments:

• According to one embodiment, the present invention can be filled with the product to be contained after the sealing of the sleeve 102 and before the sealing of the base 202. The filling then takes place through the second end intended to receive subsequently the base 202.

• According to another embodiment, the present invention can be filled with the product to be contained after the sealing of the sleeve 102 and after the sealing of the base 202. The filling then takes place through the sleeve 102.

The present invention allows protection of the product contained in the package via at least two distinct ways. The first way relates to the use of blocking materials depending on the field of application certain radiation such as ultra-violet, for example non-limiting.

One of the advantages of the present invention concerns its dimensioning. Indeed, the possibility of carrying out the present invention according to various dimensions makes it possible to use this packaging for medical applications as well, as industrial and agri-food for example non-limiting. Advantageously, the thickness of the materials used can be optimized to meet the needs and constraints of the application areas of the present invention.

The present invention has the advantage of a very realistic product feel. This advantage is in part obtained by the use of thin films and particular materials indicated above. This feeling of touching the product allows better control of the return of the product by the user, especially when the fluid is viscous or non-homogeneous. In addition, the user has the feeling of touching the product, which ensures better control and greater accuracy in the use of the present invention.

The present invention allows a significant personalization of the packaging since the outer surface thereof has a surface for printing any type of pattern or text for advertising and / or informational purposes. For example non-limiting, it is possible to print a logo, an image, a photo, a text, a title, indications of use.

The present invention has the advantage of being partly at least recyclable because at least some of the materials used are recyclable. According to a particularly advantageous embodiment, the entire packaging is recyclable.

In a similar approach, the present invention allows a significant reduction in the amount of material used for packaging and thus allows both a reduction in manufacturing costs, but also a reduction of the ecological impact of the production of the packaging. Thus, for example, the present invention allows a reduction of at least a factor of 2 in the amount of material used for a volume equivalent packaging compared to the state of the art. This reduction in the amount of material is accompanied by a reduction of at least a factor of 3 in the weight of the packaging at equivalent volume compared with the state of the art. In addition, to continue in the eco-responsible aspect of the present invention, its design and the materials used allow a restitution of at least 10% of additional product compared to the current state of the art by its maneuverability , its flexibility and geometric design. Finally, by virtue of its design and its geometry, the present invention makes it possible to reduce the storage space thus making it possible to transport an equal quantity of product at a lower cost.
