Abstract

The invention relates to a packaging box (10), including a lower portion (12), an upper portion (14) forming a cover, a strip (16), and a thread (18). Said box is particularly usable for containing wrapped portions of melted cheese. The lower portion (12) and upper portion (14) each include a base (20a, 20b) and a side portion (22a, 22b). The strip (16) is elongate in a longitudinal direction and is connected to both side portions (22a, 22b) so as to ensure that the box (10) is tamper-proof before first opening it. The thread (18) is sandwiched between the strip (16) and at least one of the lower (12) or upper (14) portions and is moreover arranged such that one end (60) of the thread can be pulled toward the outside of the box. The strip (16) comprises a weakness line (38) that extends substantially in the longitudinal direction and is arranged so as to be broken by biasing the thread (18) toward the outside of the box.

Description

Boîte de conditionnement à ouverture améliorée  Improved opening packaging box
La présente innovation concerne une boîte de conditionnement du type comprenant : The present invention relates to a packaging box of the type comprising:
- une partie inférieure et une partie supérieure formant un couvercle, lesdites parties inférieure et supérieure comprenant chacune un fond et une partie latérale ;  - a lower portion and an upper portion forming a lid, said lower and upper portions each comprising a bottom and a side portion;
- une bande, allongée dans une direction longitudinale, liée aux deux parties latérales de manière à assurer une inviolabilité de la boîte avant première ouverture, et comportant une grande face extérieure servant de support à un décor ; et  - A band, elongated in a longitudinal direction, connected to the two side portions so as to ensure tamper resistance of the box before first opening, and having a large outer surface for supporting a decor; and
- un fil, pris en sandwich entre la bande d'une part et au moins l'une des parties inférieure et supérieure d'autre part, agencé de telle sorte qu'une extrémité du fil puisse être tirée vers l'extérieur de la boîte  a yarn, sandwiched between the strip on the one hand and at least one of the lower and upper parts on the other hand, arranged in such a way that one end of the yarn can be pulled out of the box
Une telle boîte est par exemple destinée à stocker des portions de fromage fondu emballées.  Such a box is for example intended to store packaged portions of processed cheese.
Dans la suite de la description, on entendra par le terme « fromage fondu », aussi bien les fromages fondus traditionnels obtenus par la fonte de fromages en présence ou non de sels de fonte, que des spécialités fondues obtenues par la fonte de toute matière première d'origine laitière ou non en présence ou non de sels émulsifiants ou de tout autre additif utilisé dans la technologie d'obtention de ces produits.  In the remainder of the description, the term "processed cheese" will be understood to mean both traditional processed cheeses obtained by melting cheese in the presence or absence of cast iron salts, and melted specialties obtained by melting any raw material. dairy origin or not in the presence or absence of emulsifying salts or any other additive used in the technology for obtaining these products.
Les fromages fondus sont présentés à la consommation selon différentes formes, mais une des plus anciennes et des plus utilisées consiste en des portions de forme triangulaire, parallélépipédique voir cylindrique. Ces portions sont habituellement emballées séparément dans l'aluminium et regroupées dans des boîtes cylindriques ou parallélépipédiques. De façon traditionnelle, ces boîtes sont constituées d'un couvercle et d'un fond en carton plat embouti à chaud. Le maintien du couvercle sur le fond est assuré par une collerette intérieure constituée d'une bande en carton plat fermé et rendu solidaire du fond par collage.  The processed cheeses are presented for consumption in different forms, but one of the oldest and most used consists of triangular, parallelepiped and cylindrical portions. These portions are usually packaged separately in aluminum and grouped in cylindrical or parallelepiped boxes. Traditionally, these boxes consist of a lid and a bottom of hot-stamped flat cardboard. Maintaining the lid on the bottom is provided by an inner collar made of a closed flat cardboard strip and secured to the bottom by gluing.
La collerette est collée au fond.  The collar is glued to the bottom.
En position de fermeture, le couvercle s'ajuste sur la partie extérieure de la collerette. La zone de coiffage doit être suffisamment importante et peut représenter au moins la moitié de la distance entre les parois planes du fond et du couvercle.  In the closed position, the cover fits on the outside of the collar. The styling zone must be sufficiently large and may represent at least half the distance between the flat walls of the bottom and the lid.
Dans ce type de boîtes, l'inviolabilité est assurée par une bande de papier collée sur la partie cylindrique de la boîte, cette bande assurant avantageusement le décor. L'ouverture est avantageusement mais pas nécessairement assurée par un fil déposé sous la bande au niveau de la jonction du couvercle et du fond.  In this type of boxes, the inviolability is provided by a strip of paper glued to the cylindrical portion of the box, this strip advantageously providing the decor. The opening is advantageously but not necessarily provided by a wire deposited under the strip at the junction of the cover and the bottom.
Le système d'ouverture n'est pas sans présenter d'inconvénients. En effet, les cadences industrielles de pose du fil entraînent souvent un positionnement non linéaire de celui-ci et, par voie de conséquence, de nombreuses difficultés au moment de l'opération d'ouverture : difficultés de localisation du bout de fil servant d'organe de préhension, déchirage voire déchiquetage de la bande au moment de l'ouverture et disparition partielle subséquente du décor de cette dernière. The opening system is not without its disadvantages. Indeed, the industrial rates of wire laying often result in a nonlinear positioning of this and, consequently, many difficulties at the time of the opening operation: difficulties in locating the end of wire serving as a gripping member, tearing or shredding of the strip at the time of opening and subsequent partial disappearance of the decor of the latter.
De plus, après ouverture, le décor latéral de la boîte est abîmé, devient illisible et au moment de refermer la boîte, il ne se positionne pas bien pour assurer la continuité de ce dernier.  In addition, after opening, the side decoration of the box is damaged, becomes unreadable and when closing the box, it does not position well to ensure the continuity of the latter.
Afin de remédier aux inconvénients du fil on a imaginé et utilisé d'autres systèmes tels que par exemple :  In order to overcome the drawbacks of the yarn, other systems have been devised and used, for example:
- deux prédécoupes parallèles courant le long d'une bande et délimitant une bande d'arrachage le long de cette dernière, ce qui facilite l'ouverture par élimination de la bande. Si ce système s'avère plus efficace que le simple fil, il crée une bande nette d'arrachage qui a le grand inconvénient d'entraîner une rupture dans le décor latéral de la boîte.  - Two parallel precuts running along a strip and delimiting a tear strip along the latter, which facilitates opening by eliminating the band. If this system proves more effective than the simple wire, it creates a clear tear strip which has the great disadvantage of causing a break in the side decoration of the box.
- une bande d'arrachage constituée d'une bande autocollante portant le décor, collée sur la jupe ; au moment de l'ouverture, il suffit de décoller la bande pour assurer l'ouverture de la boîte avec le grand inconvénient que l'on élimine totalement le décor latéral de la boîte.  - a tear strip consisting of a self-adhesive tape bearing the decor, glued to the skirt; at the time of opening, just take off the tape to ensure the opening of the box with the great disadvantage that it eliminates completely the side decor of the box.
un fil courant le long de la bande d'arrachage se terminant par une boucle de préhension ; si ce système améliore la préhension du fil, il entraîne les mêmes défauts que le système fil unique.  a yarn running along the tear strip ending in a gripping loop; if this system improves the grip of the wire, it causes the same defects as the single wire system.
Ces systèmes ne sont pas adaptés pour les fonctions jugées indispensables à une ouverture optimisée de la boîte :  These systems are not suitable for the functions considered essential for an optimized opening of the box:
facilité, netteté de l'ouverture de la boîte,  ease, sharpness of the opening of the box,
- 'inviolabilité de la boîte avant première ouverture,  - inviolability of the box before first opening,
continuité du décor avant et après première ouverture et au cours des cycles d'ouverture-fermeture de la boîte.  continuity of the decor before and after first opening and during the opening and closing cycles of the box.
Pour assurer ces différentes fonctions, FR 2 677 336 propose une boîte de conditionnement comprenant une partie inférieure et une partie supérieure formant le couvercle, lesdites parties inférieure et supérieure comprenant chacune une partie latérale servant de support à une partie de décor de la boîte, et un organe d'ouverture de la boîte. L'organe d'ouverture est formé d'une bande pelable en matière plastique, munie d'une languette de préhension, adhérant de façon détachable aux deux parties du décor de la boîte.  To ensure these various functions, FR 2 677 336 proposes a packaging box comprising a lower part and an upper part forming the cover, said lower and upper parts each comprising a lateral part serving to support a decoration part of the box, and an opening member of the box. The opening member is formed of a peelable plastic strip, provided with a gripping tab, adhering detachably to the two parts of the decoration of the box.
Une telle boîte génère une quantité de déchets plus importante à l'ouverture (bande pelable). Ces déchets sont en plastique, c'est-à-dire dans une matière non biodégradable. Ces deux aspects sont des défauts dans un contexte où une attention plus grande est portée au respect de l'environnement. Such a box generates a larger amount of waste at the opening (peelable strip). This waste is plastic, that is to say in a non-biodegradable material. These two aspects are defects in a context where greater attention is paid to respect for the environment.
Un but de l'invention est donc d'obtenir une boîte de conditionnement dont l'aspect est meilleur que celui des boîtes à ouverture par fil, et qui soit plus écologique que la boîte décrite dans FR 2 677 336.  An object of the invention is therefore to obtain a packaging box whose appearance is better than that of wire opening boxes, and which is more environmentally friendly than the box described in FR 2 677 336.
A cet effet, l'invention a pour objet une boîte de conditionnement du type précité, caractérisé en ce que la bande comporte une unique ligne de faiblesse s'étendant sensiblement dans la direction longitudinale, adaptée pour être rompue par une sollicitation du fil vers l'extérieur de la boîte de sorte que le décor présent sur la face extérieure de la bande reste intact.  To this end, the subject of the invention is a packaging box of the aforementioned type, characterized in that the strip comprises a single line of weakness extending substantially in the longitudinal direction, adapted to be broken by a biasing of the wire towards the end. outside the box so that the decor on the outside of the strip remains intact.

Une boîte de conditionnement 10 selon l'invention est représentée sur les Figures 1 etA packaging box 10 according to the invention is shown in FIGS.
2. 2.
Cette boîte de conditionnement 10 est particulièrement destinée à stocker des portions de fromage fondu emballées. Elle pourrait également être destinée à des portions individuelles d'autres types de fromages, ou de produits alimentaires autres que des fromages. Elle pourrait également être utilisée pour conditionner des fromages entiers, non divisés en portions.  This packaging box 10 is particularly intended to store packaged portions of processed cheese. It could also be intended for individual portions of other types of cheese, or food products other than cheese. It could also be used to package whole cheese, not divided into portions.
Comme illustré sur la Figure 1 , la boîte de conditionnement 10 comporte une partie inférieure 12, une partie supérieure formant couvercle 14, une bande 16 et un fil 18.  As illustrated in FIG. 1, the packaging box 10 comprises a lower part 12, an upper cover part 14, a strip 16 and a wire 18.
Les parties inférieure et supérieure comportent chacune un fond, respectivement 20a et 20b, et une partie latérale, respectivement 22a et 22b, solidaire du fond 20a ou 20b et formée par un tronçon de tube en carton.  The lower and upper portions each comprise a bottom, respectively 20a and 20b, and a side portion, respectively 22a and 22b, integral with the bottom 20a or 20b and formed by a section of cardboard tube.
La partie inférieure comporte en outre un second tronçon de tube, non représenté, de diamètre légèrement inférieur à celui formant la partie latérale 22a, et de hauteur sensiblement supérieure, collé contre celui-ci, de manière à permettre l'emboîtement de la partie supérieure 14 sur la partie inférieure 12.  The lower portion further comprises a second tube section, not shown, of diameter slightly smaller than that forming the lateral part 22a, and of substantially greater height, glued against the latter, so as to allow the interlocking of the upper part. 14 on the lower part 12.
La partie latérale 22b comporte un bord inférieur 25. Ce bord inférieur 25 constitue le bord inférieur du couvercle 14.  The lateral portion 22b has a lower edge 25. This lower edge 25 constitutes the lower edge of the cover 14.
Comme représenté sur la Figure 1 , le bord inférieur 25 peut être au contact de la partie latérale 22a. Toutefois, de façon préférentielle, les parties latérales 22a et 22b seront distantes de 3 à 30mm selon la hauteur de la boîte.  As shown in Figure 1, the lower edge 25 may be in contact with the side portion 22a. However, preferably, the side portions 22a and 22b will be spaced from 3 to 30mm depending on the height of the box.
Les Figures 3 à 5 représentent la bande 16 de la boîte de conditionnent selon l'invention. La bande 16 assure l'inviolabilité de la boîte 10 avant première ouverture.  Figures 3 to 5 show the band 16 of the conditioning box according to the invention. The band 16 ensures the inviolability of the box 10 before first opening.
Afin de permettre une bonne recyclabilité des éléments de la boîte 10, la bande 16 est avantageusement réalisée en papier. Elle ne comporte pas de couche de matière plastique. Ce papier comprend avantageusement une majorité de fibres courtes de longueur inférieure à 2mm, de préférence inférieure à 1 ,3mm. Son grammage est avantageusement compris entre 60 et 85g. Il s'agit préférentiellement de papier couché comportant une couche de pigments fins et d'adhésifs sur au moins une face. Ce papier est par exemple du type du Sinarlux CCP produit par la société Asia Pulp Paper. La bande 16 est allongée suivant une direction longitudinale. Elle comporte une grande face intérieure 30, une grande face extérieure 32, un bord longitudinal inférieur 34 et un bord longitudinal supérieur 36. Elle présente en outre une unique ligne de faiblesse 38 qui s'étend sensiblement longitudinalement et délimite une partie inférieure 39a et une partie supérieure 39b de la bande 16. In order to allow good recyclability of the elements of the box 10, the strip 16 is advantageously made of paper. It does not have a layer of plastic material. This paper advantageously comprises a majority of short fibers less than 2 mm long, preferably less than 1.3 mm. Its grammage is advantageously between 60 and 85g. It is preferably coated paper having a layer of fine pigments and adhesives on at least one side. This paper is for example of the Sinarlux CCP type produced by Asia Pulp Paper. The strip 16 is elongate in a longitudinal direction. It comprises a large inner face 30, a large outer face 32, a lower longitudinal edge 34 and an upper longitudinal edge 36. It also has a single line of weakness 38 which extends substantially longitudinally and defines a lower portion 39a and a upper part 39b of the strip 16.
La bande 16 est de hauteur transversale sensiblement inférieure ou égale à la hauteur totale des parties latérales 22a et 22b plus, le cas échéant, la hauteur de l'intervalle séparant les parties 22a et 22b.  The band 16 is of transverse height substantially less than or equal to the total height of the side portions 22a and 22b plus, where appropriate, the height of the gap between the parts 22a and 22b.
La ligne de faiblesse 38 est placée sur la bande 16 à une hauteur telle que, lorsque la face intérieure 30 et les bords 34 et 36 de la bande 16 sont en contact avec les parties latérales 22a et 22b, la ligne de faiblesse 38 est en coïncidence avec l'intervalle entre les parties latérales 22a et 22b ou, si celles-ci sont jointives, la ligne de faiblesse 38 est en coïncidence avec le bord inférieur 25 du couvercle 14. La ligne de faiblesse 38 est préférentiellement légèrement décalée vers le bas par rapport au bord inférieur 25, ou s'étend le long du bord inférieur 25. Elle peut autrement être légèrement décalée vers le haut par rapport au bord inférieur 25, bien que cela ne constitue pas un mode préféré de réalisation de l'invention.  The line of weakness 38 is placed on the strip 16 at a height such that, when the inner face 30 and the edges 34 and 36 of the strip 16 are in contact with the lateral parts 22a and 22b, the line of weakness 38 is in coincidence with the gap between the lateral parts 22a and 22b or, if they are contiguous, the line of weakness 38 is in coincidence with the lower edge 25 of the lid 14. The line of weakness 38 is preferably slightly shifted downwards relative to the lower edge 25, or extends along the lower edge 25. It may otherwise be slightly shifted upwardly with respect to the lower edge 25, although this is not a preferred embodiment of the invention.
La ligne de faiblesse 38 comprend typiquement une alternance de points d'attache 40 et de perforations 42.  The line of weakness 38 typically comprises an alternation of attachment points 40 and perforations 42.
Ces perforations 42 sont de préférence traversantes et débouchent dans la face intérieure 30 et dans la face extérieure 32, comme illustré sur la Figure 5. Chacune présente une largeur transversale comprise entre 0,05mm et 0,5mm, avantageusement entre 0,05mm et 0,15mm, et une longueur longitudinale comprise entre 0,2mm et 1 mm, avantageusement entre 0,5mm et 0,8mm, avantageusement encore entre 0,6mm et 0,7mm. Deux perforations 42 consécutives sont espacées d'un intervalle longitudinal compris entre 0,1 mm et 1 mm, avantageusement entre 0,2mm et 0,5mm, avantageusement encore entre 0,3 et 0,4mm.  These perforations 42 are preferably through and open into the inner face 30 and into the outer face 32, as illustrated in FIG. 5. Each has a transverse width of between 0.05 mm and 0.5 mm, advantageously between 0.05 mm and 0. , 15mm, and a longitudinal length of between 0.2mm and 1mm, advantageously between 0.5mm and 0.8mm, advantageously still between 0.6mm and 0.7mm. Two consecutive perforations 42 are spaced apart by a longitudinal gap of between 0.1 mm and 1 mm, advantageously between 0.2 mm and 0.5 mm, advantageously still between 0.3 and 0.4 mm.
Chaque point d'attache 40 est constitué d'un pont de matière compris entre deux perforations consécutives 42 et reliant les parties inférieure 39a et supérieure 39b de la bande 16.  Each attachment point 40 consists of a bridge of material between two consecutive perforations 42 and connecting the lower portions 39a and 39b of the upper band 16.
La face extérieure 32 sert avantageusement de support à une partie du décor de la boîte 45. Elle est par exemple imprimée et porte une couche d'encre.  The outer face 32 advantageously supports a portion of the decoration of the box 45. It is for example printed and carries a layer of ink.
La face intérieure 30 est enduite d'un vernis répulsif anti-adhésif 50 au niveau de la ligne de faiblesse 38, sur une zone 52 s'étendant de part et d'autre de cette dernière et incluant la ligne de faiblesse 38. La zone 52 s'étend transversalement sur une largeur comprise entre 4 et 10mm, de chaque côté de la ligne de faiblesse. Un adhésif 55 enduit la totalité de la face intérieure 30. Cet adhésif 55 est avantageusement une colle. The inner face 30 is coated with a non-stick repellent varnish 50 at the level of the line of weakness 38, on an area 52 extending on either side of the latter and including the line of weakness 38. 52 extends transversely over a width of between 4 and 10 mm, on each side of the line of weakness. An adhesive 55 coats the entire inner face 30. This adhesive 55 is advantageously an adhesive.
Au niveau de la zone 52, l'adhésif 55 est déposé par-dessus le vernis 50. Le vernis répulsif 50 évite ainsi que l'adhésif 55 n'obstrue les perforations 42.  At the zone 52, the adhesive 55 is deposited over the varnish 50. The repellent varnish 50 thus prevents the adhesive 55 from clogging the perforations 42.
Selon une variante du produit selon l'invention, l'adhésif 55 peut n'enduire que le reste de la face intérieure 30 qui n'est pas enduit de vernis répulsif 50. Il peut également être appliqué sur l'extérieur des parties latérales 22a et 22b.  According to a variant of the product according to the invention, the adhesive 55 can coat only the remainder of the inner face 30 which is not coated with repellent varnish 50. It can also be applied on the outside of the lateral parts 22a. and 22b.
Comme illustré sur les Figures 1 et 2, la bande 16 est collée contre les parties latérales 22a et 22b de façon à ce que les bords 34 et 36 affleurent ou sont à proximité des fonds 20a et 20b.  As illustrated in Figures 1 and 2, the strip 16 is glued against the side portions 22a and 22b so that the edges 34 and 36 are flush or are close to the bottoms 20a and 20b.
Le fil 18 est quant à lui constitué de polyester et de coton, de préférence avec une majorité de polyester. Il est placé en coïncidence avec la ligne de faiblesse 38, le long de la face intérieure 30 de la bande 16. Il peut être légèrement décalé transversalement vers le haut ou vers le bas. Il s'étend de préférence soit le long du bord inférieur 25 du couvercle 14, soit dans l'intervalle entre les parties 22a et 22b lorsque celles-ci ne sont pas jointives. Il est pris en sandwich entre la bande 16 d'une part et au moins l'une des parties inférieure 12 et supérieure 14 de la boîte d'autre part.  The yarn 18 is made of polyester and cotton, preferably with a majority of polyester. It is placed in coincidence with the line of weakness 38, along the inner face 30 of the strip 16. It may be slightly shifted transversely upwards or downwards. It preferably extends either along the lower edge 25 of the cover 14, or in the gap between the parts 22a and 22b when they are not contiguous. It is sandwiched between the band 16 on the one hand and at least one of the lower 12 and upper 14 parts of the box on the other hand.
La bande 16 fait au moins 100% et de préférence 1 10% du tour de la boîte, avec éventuellement une zone où ses deux extrémités longitudinales se recouvrent mutuellement. Le fil 18 fait également au moins 100% du tour de la boîte et peut être plus long que la bande 16, de façon à ce qu'une extrémité 60 du fil dépasse à l'extérieur conformément à la figure 1 .  The strip 16 is at least 100% and preferably 1 10% of the circumference of the box, possibly with a zone where its two longitudinal ends overlap each other. The yarn 18 also makes at least 100% of the round of the box and may be longer than the strip 16, so that one end 60 of the yarn protrudes outside in accordance with FIG.
Pour le montage de la boîte de conditionnement 10, on commence par réaliser les perforations 42 dans la bande 16 selon la ligne de faiblesse 38. Puis on enduit la face intérieure 30 de la bande 16 d'un vernis répulsif au niveau de la zone 52. Enfin, on enduit la totalité de la face intérieure 30 d'adhésif 55 et on dispose le fil 18 sur la face intérieure 30 le long de la ligne de faiblesse 38. Le fil 18 adhère par contact à la bande 16 au moyen de l'adhésif 55.  For the assembly of the packaging box 10, we first realize the perforations 42 in the strip 16 along the line of weakness 38. Then the inner face 30 of the strip 16 is coated with a repellent varnish at the zone 52 Finally, the entire inner surface 30 of adhesive 55 is coated and the wire 18 is placed on the inner face 30 along the line of weakness 38. The wire 18 adheres by contact to the strip 16 by means of the adhesive 55.
Lorsque la boîte 10 formée de la partie inférieure 12 et du couvercle 14 est fermée après remplissage, on applique par collage, par exemple au moyen d'une machine industrielle, la bande 16 munie du fil 18 sur la face externe des parties latérales 22a et 22b de façon à ce que les bords 34 et 36 soient jointifs ou en léger décalage par rapport aux fonds 20a et 20b et à ce que l'extrémité 60 du fil 18 soit facilement accessible.  When the box 10 formed of the lower part 12 and the lid 14 is closed after filling, the strip 16 provided with the wire 18 is applied by gluing, for example by means of an industrial machine, to the external face of the lateral parts 22a and 22b so that the edges 34 and 36 are contiguous or slightly offset from the funds 20a and 20b and that the end 60 of the wire 18 is easily accessible.
La ligne de faiblesse 38 présente une résistance suffisante pour permettre, avant première ouverture, la manipulation de la boîte 10 sans risque de désolidarisation des parties inférieure 12 et supérieure 14. Lorsque l'utilisateur exerce une traction sur l'extrémité 60 du fil vers l'extérieur de la boîte - l'utilisateur tire sur le fil 18 par exemple selon une direction perpendiculaire à la bande 16, ou légèrement inclinée par rapport à la direction perpendiculaire - le fil 18 vient cisailler les points d'attache 40 de la ligne de faiblesse 38. Les points d'attache 40 étant de faible longueur et les fibres du papier constituant la bande 16 étant courtes, il y a très peu de délaminage, de sorte que le décor présent sur la face extérieure 32 reste intact. En outre, la force exercée sur le fil 18 pour permettre le cisaillement des points d'attache 40 reste ainsi inférieure à la force d'adhésion du fil 18 à la bande 16, ce qui permet d'éviter un décollement impromptu du fil 18. The line of weakness 38 has sufficient strength to allow, before first opening, the handling of the box 10 without the risk of separation of the lower portion 12 and upper 14. When the user pulls on the end 60 of the wire towards the outside of the box - the user pulls on the wire 18 for example in a direction perpendicular to the strip 16, or slightly inclined relative to the perpendicular direction - The wire 18 is shearing the attachment points 40 of the line of weakness 38. The attachment points 40 being of short length and the fibers of the paper constituting the strip 16 being short, there is very little delamination, of so that the decor present on the outer face 32 remains intact. In addition, the force exerted on the wire 18 to allow the shearing of the attachment points 40 thus remains less than the adhesion strength of the wire 18 to the band 16, which makes it possible to avoid an impromptu detachment of the wire 18.
Lorsque tous les points d'attache 40 ont été rompus, les parties inférieure 12 et supérieure 14 se retrouvent désolidarisées. Il ne reste alors plus à l'utilisateur qu'à séparer le couvercle 14 de la partie inférieure 12 pour ouvrir la boîte et découvrir, par exemple, des portions de fromage fondu emballées individuellement.  When all the attachment points 40 have been broken, the lower 12 and upper 14 parts are found uncoupled. It then remains for the user to separate the lid 14 of the lower part 12 to open the box and discover, for example, portions of cheese individually wrapped.
Au moment de refermer la boîte, il suffit de repositionner correctement le couvercle 14 sur la partie inférieure 12 de façon à reconstituer le décor, ce dernier étant resté intact du fait de la netteté du système d'ouverture.  When closing the box, just reposition the cover 14 correctly on the lower part 12 so as to reconstruct the decor, the latter remained intact because of the sharpness of the opening system.
La boîte de conditionnement selon l'invention aura ainsi une inviolabilité assurée par la bande avant ouverture, mais restera attractive après ouvertures et fermetures successives, un des grands avantages étant le maintien de l'intégralité du décor tout au long des cycles d'ouverture-fermeture de la boîte.  The conditioning box according to the invention will thus have an inviolability ensured by the band before opening, but remain attractive after successive openings and closures, one of the great advantages being the maintenance of the entire decoration throughout the opening cycles. closing the box.
Elle présentera également un aspect écologique et économique grâce à l'emploi du papier comme matériau constitutif de la bande de fermeture de la boîte, le seul déchet résultant de l'ouverture de la boîte étant le fil 18.  It will also have an ecological and economic aspect through the use of paper as a constituent material of the closure band of the box, the only waste resulting from the opening of the box being the wire 18.
Sa bande 16 aura en outre un rendu d'impression supérieure à une bande papier classique grâce par exemple à l'emploi de papier couché de qualité supérieure du type du Sinarlux CCP produit par la société Asia Pulp Paper. La qualité du rendu d'impression sera semblable à celle obtenue avec la bande de matière de plastique de FR 2 677 336.  Its strip 16 will also have a print rendering superior to a conventional paper tape thanks for example to the use of high quality coated paper of the Sinarlux CCP type produced by Asia Pulp Paper. The quality of the print rendering will be similar to that obtained with the plastic material strip of FR 2 677 336.
Enfin, la boîte de conditionnement selon l'invention présente l'avantage de pouvoir être produite sur les mêmes machines que celles produisant les boîtes de conditionnement à fil standards.  Finally, the packaging box according to the invention has the advantage of being able to be produced on the same machines as those producing the standard wire packaging boxes.
La boîte de conditionnement représentée ici est à section circulaire, mais l'invention ne saurait se réduire à ce seul type de boîte et est également envisageable sur d'autres types de boîte, par exemple à section rectangulaire ou de forme quelconque.  The packaging box shown here is circular in section, but the invention can not be reduced to this type of box only and is also possible on other types of box, for example rectangular section or any shape.
Selon certaines variantes possibles du produit selon l'invention, la ligne de faiblesse 38 peut être composée de perforations non traversantes au lieu de perforations traversantes, ou être constituée d'un sillon continu. Elle n'est pas forcément rectiligne et peut comporter des portions à une hauteur différente, former une frise ondulée ou prendre toute forme qui pourra sembler adaptée. According to some possible variants of the product according to the invention, the line of weakness 38 may be composed of non-through perforations instead of through perforations, or consist of a continuous groove. It is not necessarily straight and may have portions at a different height, form a wavy frieze or take any form that may seem appropriate.
L'extrémité 60 du fil 18 peut également être solidaire d'une languette de préhension. Cette languette de préhension peut adhérer partiellement à la face extérieure 32 de la bande 16.  The end 60 of the wire 18 may also be secured to a gripping tab. This gripping tongue may partially adhere to the outer face 32 of the strip 16.
