- the present invention relates to a process for packaging products, in particular food products such as chocolate bars or bars or the like, in which a packaging material is used which consists of a sheet of heat-sealable aluminum strip.
- the chocolate bars are packaged in a first package consisting, for example, of a multilayer complex, heat sealable or not, one of the layers of which is for example aluminum folded by an appropriate mechanism, known per se, then in a second packaging consisting of a banner or printed paper label.
- a first package consisting, for example, of a multilayer complex, heat sealable or not, one of the layers of which is for example aluminum folded by an appropriate mechanism, known per se
- a second packaging consisting of a banner or printed paper label.
- One-step packaging machines have been developed, using one or more packaging materials folded simultaneously in a folding box.
- This type of packaging is neither waterproof nor tamper-proof.
- the present invention proposes to overcome the aforementioned drawbacks by performing a folding in a single operation, which has the appearance as well as the advantages of a folding of the conventional type.
- an asymmetrical tube is formed, using this packaging material around the product, such that one of the edges of the sheet exceeds 1 'other edge and forms a foldable cover tab, in that one carries out a longitudinal sealing of the tube by sealing the other edge of the sheet against the base of this tab, in that one forms the lateral folds that it is folded against the underside of the product and in that the tongue is folded over this underside so as to hide the lateral folds.
- the product consisting, for example, of a chocolate bar 10 is surrounded by a sheet 11 of packaging material consisting of heat-sealable aluminum, that is to say coated with a heat-bonding coating such as for example polyethylene.
- a tube is formed around the product and the edge 12 is sealed against the inner surface of the base of a covering tongue 13 produced by asymmetrically arranging the two longitudinal edges of the sheet 11 as shown in FIG. 1.
- the cover tab 13 can be point-sealed or optionally glued along line 17 or along at least part of this line.
- This process therefore makes it possible to end up with a packaging which has a classic appearance, the lateral folds not being visible, since they are hidden by the cover tab.
- the covering tab preferably has a width sufficient to enable it to cover almost the entire underside 16 of the product.

Abstract
Le procédé à réaliser un tube autour du produit, à l'aide d'une feuille d'aluminium thermoscellable, à former des plis latéraux (14, 15) et à rabattre une languette de recouvrement sur la surface inférieure (16) du produit pour cacher les plis latéraux. Si l'on scelle la languette de recouvrement contre cette face inférieure, on peut garantir l'inviolabilité du produit.The method of making a tube around the product, using a heat-sealable aluminum foil, of forming side folds (14, 15) and of folding down a covering tab on the lower surface (16) of the product to hide the side folds. If the cover strip is sealed against this underside, the product can be tampered with.
Description
La présente invention concerne un procédé de conditionnement de produits, notamment de produits alimentaires tels que tablettes ou bâtons de chocolat ou similaires, dans lequel on utilise un matériau d'emballage constitué par une feuille d'une bande d'aluminium thermoscellable.The present invention relates to a process for packaging products, in particular food products such as chocolate bars or bars or the like, in which a packaging material is used which consists of a sheet of heat-sealable aluminum strip.
Elle concerne également le conditionnement obtenu par ce procédé.It also relates to the packaging obtained by this process.
Habituellement, les tablettes de chocolat sont conditionnées dans un premier emballage constitué, par exemple, par un complexe multicouche thermoscellable ou non, dont une des couches est par exemple de l'aluminium plié par un mécanisme approprié, connu en soi, puis dans un second emballage constitué par une banderole ou une étiquette en papier imprimé. Ce procédé, devenu classique, continue à être utilisé sur une très large échelle. Toutefois, il nécessite des installations d'approvisionnement et de pliage d'au moins deux matériaux d'emballage différents. Par ailleurs, ce type d'emballage ne répond pas nécessairement au critère d'inviolabilité.Usually, the chocolate bars are packaged in a first package consisting, for example, of a multilayer complex, heat sealable or not, one of the layers of which is for example aluminum folded by an appropriate mechanism, known per se, then in a second packaging consisting of a banner or printed paper label. This process, which has become classic, continues to be used on a very large scale. However, it requires facilities for supplying and folding at least two different packaging materials. Furthermore, this type of packaging does not necessarily meet the inviolability criterion.
On a développé des machines de conditionnement à une seule opération, utilisant un ou plusieurs matériaux d'emballage pliés simultanément dans une boite de pliage. Ce type d'emballage n'est ni étanche, ni inviolable.One-step packaging machines have been developed, using one or more packaging materials folded simultaneously in a folding box. This type of packaging is neither waterproof nor tamper-proof.
Donc, actuellement, seules les machines à deux opérations sont capables de réaliser un conditionnement étanche et inviolable.Therefore, at present, only two-operation machines are capable of achieving sealed and tamper-proof packaging.
Ces machines présentent, bien entendu l'inconvénient d'être particulièrement encombrantes et coûteuses.These machines have, of course, the drawback of being particularly bulky and expensive.
La présente invention se propose de pallier les inconvénients susmentionnés en réalisant un pliage en une seule opération, qui présente l'aspect ainsi que les avantages d'un pliage de type classique.The present invention proposes to overcome the aforementioned drawbacks by performing a folding in a single operation, which has the appearance as well as the advantages of a folding of the conventional type.
Ce but est atteint par le procédé selon l'invention, caractérisé en ce que l'on forme, à l'aide de ce matériau d'emballage autour du produit, un tube asymétrique tel que l'un des bords de la feuille dépasse l'autre bord et forme une languette de recouvrement rabattable, en ce que l'on effectue un scellage longitudinal du tube en scellant l'autre bord de la feuille contre la base de cette languette, en ce que l'on forme les plis latéraux que l'on rabat contre la face inférieure du produit et en ce que l'on rabat la languette par-dessus cette face inférieure de manière à cacher les plis latéraux.This object is achieved by the method according to the invention, characterized in that an asymmetrical tube is formed, using this packaging material around the product, such that one of the edges of the sheet exceeds 1 'other edge and forms a foldable cover tab, in that one carries out a longitudinal sealing of the tube by sealing the other edge of the sheet against the base of this tab, in that one forms the lateral folds that it is folded against the underside of the product and in that the tongue is folded over this underside so as to hide the lateral folds.
La présente invention sera mieux comprise en référence à la description d'un exemple de réalisation préféré et du dessin annexé dans lequel:
- La fig. 1 représente une vue en perspective d'une première phase du procédé selon l'invention, au cours de laquelle on forme le tube de matériau d'emballage autour du produit,
- La fig. 2 représente une vue identique à celle de la fig. 1, mais illustrant une phase ultérieure du procédé selon l'invention,
- La fig. 3 représente la phase de rabattement de la languette de recouvrement, et
- La fig. 4 représente une vue en perspective du produit conditionné selon le procédé de l'invention.
- Fig. 1 represents a perspective view of a first phase of the method according to the invention, during which the tube of packaging material is formed around the product,
- Fig. 2 shows a view identical to that of FIG. 1, but illustrating a later phase of the method according to the invention,
- Fig. 3 represents the phase of folding down the covering tab, and
- Fig. 4 shows a perspective view of the product packaged according to the method of the invention.
En référence à la fig. 1, le produit constitué, par exemple, par une tablette de chocolat 10 est entouré d'une feuille 11 de matériau d'emballage constitué par de l'aluminium thermoscellable, c'est-à-dire revêtu d'un enduit thermocollant tel que par exemple le polyéthylène. On forme un tube autour du produit et on scelle le bord 12 contre la surface intérieure de la base d'une languette de recouvrement 13 réalisée en disposant asymétriquement les deux bords longitudinaux de la feuille 11 comme le montre la fig. 1.With reference to fig. 1, the product consisting, for example, of a
On forme ensuite, comme le montre la fig. 2, les plis latéraux 14 et 15 à l'aide de poussoirs agissant dans le sens des flèches A et B. Cette technique est bien connue et ne sera pas décrite plus en détail dans ce texte. Lorsqu'ils sont formés et avant d'être rabattus, ces plis latéraux sont scellés.Then, as shown in fig. 2, the side folds 14 and 15 using pushers acting in the direction of the arrows A and B. This technique is well known and will not be described in more detail in this text. When formed and before being folded down, these side folds are sealed.
Lorsque les deux plis latéraux 14 et 15 sont entièrement rabattus contre la face inférieure 16 du produit, on rabat, comme le montre la fig. 3, dans le sens de la flèche C, la languette de recouvrement 13, pour aboutir à un produit conditionné tel que représenté par la fig. 4. La languette de recouvrement 13 peut être scellée par points ou éventuellement collée le long de la ligne 17 ou le long d'une partie au moins de cette ligne.When the two
Ce procédé permet donc d'aboutir à un emballage qui présente un aspect classique, les plis latéraux n'étant pas apparents, puisqu'ils sont cachés par la languette de recouvrement.This process therefore makes it possible to end up with a packaging which has a classic appearance, the lateral folds not being visible, since they are hidden by the cover tab.
A cet effet, la languette de recouvrement a, de préférence, une largeur suffisante pour lui permettre de recouvrir quasiment en totalité la face inférieure 16 du produit.To this end, the covering tab preferably has a width sufficient to enable it to cover almost the
