Definitions
- the present invention relates to the field of packaging bags.
- the present invention relates to the field of packaging bags comprising opening / closing means, for example and not limitatively in the form of complementary profiles.
- Most closing devices known for this purpose comprise two complementary sections, for example of the male / female type or of the velvet / hook type, or even of the complementary hook type, carried by respective support webs.
- Document FR 2 628 067 has in particular proposed a bag comprising two main walls comprising two complementary closure profiles carried by respective support webs fixed respectively to the walls.
- One of the support webs is fixed to the wall of the corresponding bag in a conventional manner, for example by welding its upper edge and its lower edge to the wall of the bag or, alternatively, by welding its entire surface to the wall from the sachet.
- the other support veil on the other hand is fixed on the associated wall at the level of a fixing zone which is not superimposed on the profile but offset with respect to the latter in order to articulate this support veil on the wall at the level of the attachment area.
- Such a sachet finds, for example, application in the field of packaging of harmful products, such as laundry tablets. Indeed, it is important to be able to guarantee to users that the sachet remains closed between two uses, in order to prevent in particular children from accessing its content, while leaving the possibility for parents to open and close the sachet. several times without risking damage, and preferably without successive openings and closings being too difficult.
- a bag comprising a closure assembly comprising a first and a second support web connected respectively to the first and to the second wall and each comprising a complementary closure element.
- the first support veil is connected discontinuously along its length to the first wall of the bag so as to provide at least one passage between this first support veil and the first wall of the bag from the outside of the bag.
- An objective of the invention is therefore to propose a sachet comprising opening / closing means, for example and not limitatively in the form of complementary profiles, and presenting a system making it possible to open said opening / closing means in a simple manner and rapid by an adult and which is also easily industrializable.
- the invention provides a sachet comprising:
- first and second walls connected together so as to define lateral sides, a mouth and a bottom of the bag
- a closure assembly comprising a first and a second support web connected respectively to the first and to the second wall and each comprising a complementary closure element.
- the first support veil has an upper edge adjacent to the mouth and a lower edge adjacent to the bottom and being fixed on the first wall at its upper edge continuously between the lateral sides of the bag. Furthermore, a through window is formed in the first support veil, between the closure element and its upper edge, said window being closed and not opening onto the upper edge, so as to allow local deformation of the first clean support veil. to modify the local relative orientation of the closure elements when the walls of the bag are separated and facilitate the opening of the closure assembly.
- the window is delimited either by a cutting line, or by a line of weakness, said line of weakness comprising a precut of the first support web or a local thinning of said first support web.
- the bag also includes a removable patch attached and fixed to the window.
- the first support veil is fixed to the first wall by means of a weld line, the window extending between the weld line and the closure element.
- the window does not extend to the part of the support screen which carries the closing element.
- the first support veil is also fixed to the first wall in an area adjacent to the closure element and / or at its lower edge.
- the second support veil having an upper edge adjacent to the mouth and a lower edge adjacent to the bottom and being fixed on the second wall at its upper edge continuously between the lateral sides of the bag, and in which a through window is also formed in the second support web, between the closure element and its upper edge, said window being closed and not opening onto the upper edge of the second support web, so as to allow local deformation of the second support web specific to modify the local relative orientation of the closure elements when the walls of the bag are separated and facilitate the opening of the closure assembly.
- the window formed in the second support veil extends opposite the window formed in the first support veil.
- the window formed in the second support veil is substantially identical in shape and dimensions to the window formed in the first support veil.
- the second support veil is intact and has no window.
- the window has a length, in the direction extending between the sides of the bag, between 12 mm and 35 mm.
- the second support veil having an upper edge adjacent to the mouth and a lower edge adjacent to the bottom and being fixed on the second wall at its upper edge continuously between the lateral sides of the bag, and in which the second veil support is fixed on the second wall at its upper edge and its lower edge.
- the second support web is articulated on the second wall so that the traction on the walls of the bag when the complementary closure elements are engaged causes the rotation of the support webs around said complementary closure element.
- the second support veil is fixed on the second wall in a localized area which is not superimposed with the closing element and which is offset with respect to said closing element, so that the second support veil is articulated on the second wall.
- first and second support walls are connected to the first and to the second wall by means of a first and a second extension wall, respectively, at least one of the support walls being attached to the wall away from its upper edge.
- the complementary closing elements each comprise at least one complementary profile, preferably at least two complementary profiles, for example between three and six complementary profiles.
- All or part of the complementary sections includes sequential alterations substantially parallel to the lateral sides, typically sequential crushings.
- Figure 1 is a detailed front view of a portion of a first embodiment of a bag according to the invention.
- Figure 2 is a top view of a second embodiment of a bag according to the invention, while a user is about to open said bag.
- Figure 3 is a view of the bag of Figure 2 being opened by the user.
- a bag 1 comprises, in a conventional manner per se, a first and a second wall 10, 20 connected together so as to define a bottom 2, lateral sides 3 and a mouth 4 of the bag 1, the mouth 4 extending to the opposite of its bottom 2.
- the bag 1 can be produced using a single sheet folded back on itself and welded on two sides or with several sheets, for example two sheets welded together at their sides, preferably according to edges connecting the walls and forming the lateral sides and the bottom 2 of the bag 1.
- the bag 1 further comprises a closure assembly.
- the closure assembly extends close to the mouth.
- the closure assembly comprises a first and a second support web 30, 35 connected respectively to the first and to the second wall 10, 20.
- Each support web 30, 35 carries at least one complementary closing element 6, 7, for example of the complementary profile type, velvet / hook band, etc.
- the first support web 30 has an upper part 31 ending at its free end (mouth side 4) with an upper edge 33 and a lower part 32 ending at its free end (bottom side 2) with a lower edge 34.
- the lower part 32 also carries all or part of the closure element 6.
- the first support web 30 is continuously attached to the first wall 10 at its upper edge 33, over its entire length between the lateral sides 3 of the bag 1, along a first weld line 11. Such fixing is conventional and can therefore be carried out easily at high speed on an industrial scale.
- the weld 11 can be of the thermal weld type, an ultrasonic weld, for example spot welding, or both (carried out successively).
- a window is produced in the first support web 30 between its upper edge 33 and the closing element 6, at a distance from the first weld line 11, said window 40 allowing access to the internal face of the first wall 10 through the first support web 30, from the outside of the bag 1.
- the window 40 thus formed in the first support web 30 is closed and does not open onto the upper edge 33 of the first support web 30.
- the window is made in only part of said support veil 30, so that it does not extend over the entire length or the entire height of the support veil 30.
- length we understand the dimension which extends along of the direction of extension of the closure assembly, between the lateral sides 3 of the bag 1, by “height” is understood the dimension which extends perpendicular to the direction of extension of the closure assembly, from the '' mouth 4 towards the bottom 2 of the bag 1.
- the window 40 does not open onto the closing element 6 in order to guarantee the sealing of the bag.
- the closure element 6 is continuous over its entire length between the lateral sides 3 of the bag 1.
- a window 40 is particularly advantageous in the case of a bag 1 whose closure assembly is difficult to open, such as a closure assembly articulated on at least one of the walls of the bag 1, but also finds application when the closure assembly is conventional (non-articulated) and made for example of polypropylene since such closure assemblies 3 are very difficult to open from outside, even by an adult.
- a user need only:
- the lower part 32 of the first support web 30 can also be fixed on the first wall 10.
- the lower part 32 can be fixed along at least a second continuous weld line 12 between the lateral sides 3 of the bag 1, at any height between the zone of the lower part 32 of the first support web 30 which carries the closure element 6 and its lower edge 34.
- the second weld line 12 may extend at the level of the lower edge 34 or at the level of the closure element 6.
- the bag 1 can include both a second weld line 12 at the lower edge 34 of the first support web 30 and a third weld line 13 at the closure element 6.
- the lower part 32 of the first support web 30 can be fixed discontinuously to the first wall 10 of the bag, as long as this discontinuity does not prevent the transmission of the forces applied by the thumb to the wall 10.
- at least the portion of the lower part 32 of the first support web 30 which is underlying the window 40 is connected to the first wall 10.
- the window 40 allows the thumb to pass through the other side of the support web 30 in order to locate the point of application of the force near the closure elements 6, 7 or the lower part 32 of the first support web 30 (depending on the height of the window 40, areas for fixing the lower part 32 of the first support web 30 and the depth of insertion of the user's thumb into the window 40) (see FIGS. 2 and 3).
- gripping the first wall 10 behind the first support web 30 makes it possible to move the area of application of the force away from the upper part 31 of the first support web 30 for the locate at the level of the closure element 6 or of its lower part 32 and therefore of limiting the rotation of the closure assembly due to the spacing of the walls 10, 20.
- This has the effect of bringing the direction of application closer together. of the force on the closing elements 6, 7 of the separation direction.
- the manufacture of the bag 1 is greatly facilitated in comparison with the production of a discontinuous weld of so as to form a passage behind the support web 30, since the usual manufacturing processes can be implemented. It then suffices to make the window 40.
- the window 40 is produced by local cutting of the first support web 30.
- the cutting can in particular be carried out using an anvil or a die punch, as is conventionally used in the field.
- anvil or a die punch as is conventionally used in the field.
- the window 40 is formed in the first support web 30 by producing a line of weakness, either by local pre-cutting of the first support web 30, or by local thinning of said first support web 30 (without removal of material) .
- a line of weakness implies that the window 40 remains closed, until its first opening by the user. Window 40 can therefore serve as a witness inviolability guaranteeing that no third party had prior access to the user to the contents of the sachet 1. If necessary, the rupture of the line of weakness can also be dimensioned so as to make the first opening difficult, increasing thus the difficulty for a child to open the sachet 1 for the first time.
- the line of weakness extends over the entire periphery of the window 40, so that the window can be easily detached from the first support web 30.
- the line of weakness s 'extends over only part of the periphery of the window 40, the rest of its periphery being intact or, on the contrary, cut to form an opening opening.
- the window 40 can also be covered by a patch, attached and fixed to the first support web 30 so as to mask it in whole or in part, and form thus a (other) witness of inviolability.
- the patch can be attached using an adhesive or a welding line.
- the first opening of the bag 1 requires, prior to the step of introducing the thumbs into the window 40, a step of opening window 40 by breaking the line of weakness and / or removing the patch.
- the window 40 may have any shape capable of allowing the passage of an inch.
- the border delimiting the window 40 does not include corners but rounded edges in order to avoid creating incipient fractures.
- the window 40 can be circular, oval, rectangular with rounded corners, etc.
- the tensile force applied to the walls 10, 20 has the effect of rotating the closure assembly and the align with the direction of application of this force, either perpendicular to the direction of separation of the closure elements 6 (said direction of separation extending perpendicular to the plane of the he
- a single window 40 for one of the thumbs is produced in the first support web 30 is arranged.
- the second support web 35 can then be intact and fixed in a conventional manner to the wall of the bag (for example over its entire surface or at its upper and lower edges, or even at a localized area so as to form a hinge, etc.).
- first and the second support web 30, 35 can be connected according to identical or different techniques to the associated wall 10, 20: for example, the first support web 30 can be attached and fixed to the first wall 10 after completion. of the window 40, while the second support web 35 may have come integrally with the second wall 20.
- a window 40 is produced both in the first support web 30 and in the second support web 35, said windows 40 being configured to receive the first inch and the second inch, respectively.
- At least one second window 40 can be produced locally in the second support web 35 between its upper edge 38 and the closing element 7 so as to allow access to the internal face of the second wall 20 through the second support web 35, from the outside of the bag 1.
- This second window 40 is produced at a distance from the weld line of the upper edge 38 of the second support web 35 on the second wall 20, so that the window 40 of the second support web 35 is closed and does not open onto the upper edge 38 of the second support web 35.
- the second window 40 can be produced in a similar manner to the first window, by cutting and / or making a line of weakness, and possibly be masked at least partially by a patch.
- the windows 40 also do not open onto the closure element 7 in order to guarantee the tightness of the bag.
- the closure element 7 is continuous over its entire length between the lateral sides 3 of the bag 1.
- the windows 40 formed in the first support web 30 and in the second support web 35 extend opposite one another, in order to facilitate the gripping of the bag and its opening by a user.
- the first support web 30 and the second support web are symmetrical with respect to the plane passing through the lateral sides 3 of the bag 1.
- the second support web 35 is then fixed over its entire length, between the lateral edges of the bag 1, at its upper edge 38 along a first weld line, and the case if necessary at a second and / or third weld line at its closure element 7 and its lower edge (or, as a variant, discontinuously in its lower part, in a similar manner to the part lower 32 of the first support web 30).
- the or each window 40 extends along a substantial height of the first associated support web 30, 35, in order to allow the user to better block the movements of the first support web 30.
- the or each window 40 may extend over at least 75% of the height of the upper part 31, 36 which is delimited on the one hand by the closing element 6, 7 and on the other hand by the upper edge 33, 38 of the associated support web 30, 35.
- the window 40 when the window 40 does not extend over the majority of the height of the upper part 31, the window 40 is preferably closer to the closure element 6, 7 than to the upper edge 31, 36 , to facilitate user access to the area behind the closure.
- the bag 1 may include more windows 40 formed in one and / or the other of the support webs 30, 35. However, the increase in the number of windows 40 also increases the risks that a child will find said windows. windows 40 and manages to open the bag 1. In order to allow the passage 40 of an inch, preferably of the thumb of an adult, the window 40 has a length, in the direction of extension of the closure assembly between the lateral sides 3 of the bag 1, between 12 mm and 35 mm.
- the window or windows 40 are closer to one of the lateral sides 3 of the bag 1 than to the other of said lateral sides 3, so as not to extend centrally between the lateral sides 3 of the bag 1. In this way, each window 40 is less likely to be identified when handling the bag 1.
- the part of the border delimiting the window 40 which is closest to one of the lateral sides 3 of the bag 1 can extend at a distance between 10% and 30% of the total distance between the lateral sides 3 of the bag 1, that is to say that for a bag 1 having a length of 100 mm between the lateral sides 3, the part in question of the edge of the window 40 extends at a distance of between 10 mm and 30 mm from the closest lateral side 3.
- each closure element 6, 7 comprises several complementary profiles (see FIG. 1), preferably between three and six complementary profiles, for example five.
- the complementary profiles 6, 7 can be of the male / female, male / male type (arrow-shaped profiles) velvet / hooks, or even of the complementary hook type.
- the complementary profiles 6, 7 can be altered sequentially by forming successive alterations along the complementary profiles 6, 7 in a direction transverse to the support webs.
- Sequential alterations are local sequential modifications of the complementary sections 6, 7, which can in particular include sequential crushing and / or sequential incisions without removal of material (i.e. either only sequential overwrites, or only sequential incisions, or both sequential overwrites and sequential incisions) and / or sequential notches with material removal.
- all or part of the complementary sections 6, 7 may include sequential alterations.
- several complementary profiles 6, 7 can comprise sequential alterations while at least one complementary profile 6 can remain intact, or vice versa.
- the closure assembly may include, without limitation:
- the closure assembly may in particular be made of polypropylene (PP) to make it difficult to open in the absence of the window 40.
- the second support web 35 can in particular be fixed on the second wall 20 in a localized area which is not superimposed with the closure element 6 and which is offset with respect to said closure element 6, so that the second support web 35 is articulated on the second wall 20.
- Such a fixing has for example been described in the document FR 2 628 067 in the name of the Applicant.
- the localized zones can be arranged on respective opposite parts of the support webs 30, 35 (here the upper part 31 and the lower part), respectively on either side of the closing elements 6, 7 complementary, so that one of the articulated webs is directed towards the inside of the bag 1 while the other articulated web is directed towards its mouth.
- Such a configuration is for example described in the document FR 2 963 927 in the name of the Applicant.
- a first support web 30 and a second support web 35 can be connected to the first and to the second wall 10, 20 by means of a first and a second extension web, respectively, one at less of the support webs 30, 35 being fixed to the extension web at a distance from its upper part 31, 36.
- Such a fastening has for example been described in the document FR 3 025 499 in the name of the Applicant.
- An additional wall having a first panel connected to the second wall 20 near the mouth of the bag 1 and a second panel connected to the first wall 10.
- the additional wall is folded between the first panel and the second panel along d 'a fold so that the second side extends towards the mouth.
- the first support veil 30 is fixed to the second wall 20 and the second support veil 35 is fixed to the second section of the additional wall, so that a spacing stress on the first and second walls 10, 20 of the bag 1 when the complementary sections 6, 7 are engaged causes a rotation of the closure device around the second support web 35.
- Such a fixing has for example been described in the document FR 3 034 760 in the name of the Applicant.
- the walls 10, 20 of the bag 1 can be made of an opaque material (not transparent), so as to reduce the possibility for children to see the closure assembly through the walls 10, 20.
- the walls 10, 20, the support webs 30, 35 and the complementary closure elements 6 can be made from a single material, in particular one of the following materials: polypropylene PP, poly (ethylene terephthalate) PET , PE polyethylene, HDPE high density polyethylene, LDPE low density polyethylene and their associated copolymers, ethylene copolymers and / or propylene copolymers.
- these different elements of the bag 1 can be produced from different materials. Mention may in particular be made, without limitation, of a bag 1 comprising a first wall 10 and a second wall 20 made of poly (ethylene terephthalate) and / or of polyethylene and a closure assembly (support webs 30, 35 and additional closing elements 6) made of polypropylene.
- first and second walls 10, 20 may have a thickness of between 30 micrometers and 200 micrometers, typically of the order of 60 micrometers to 150 micrometers, in particular when said walls are formed from one of the materials described above. - above.
