Abstract

The package consists of a backing (1), e.g. of plastic-coated card, and a covering layer (2) of a transparent plastic which is connected to the backing by a welded seam (2c). The seam contains a bubble (2d) filled with gas which is isolated from the outside and which, when opened, forms a tongue for opening the package along the seam. The bubble (2d) is dome-shaped and surrounded by two separate branches of the weld seam (2'c,2"d) and has a cut (2'd) made part-way through its surface on the outside of the bubble to facilitate opening. In a variant of the design a number of bubbles can be made at intervals round the weld seam.

Description

La présente invention vise des perfectionnements apportés aux emballages composés de deux éléments assemblés l'un avec l'autre d'une manière quelconque et elle a trait plus particulièrement à un organe facilitant la séparation desdits éléments entre eux pour avoir accès au contenu de l'emballage.The present invention relates to improvements made to packages made up of two elements assembled with each other in any way and it relates more particularly to a member facilitating the separation of said elements from one another in order to have access to the contents of the packaging.

Il existe un grand nombre d'emballages de ce type réalisés généralement chacun au moyen d'un support constitué par une plaque en carton plastifié ou analogue sur laquelle est appliquée par soudure une feuille de matière plastique transparente de recouvrement qui est pourvue d'une coque propre à renfermer un article. Dans la technique, un tel emballage est appelé "blister".There are a large number of packages of this type generally produced each by means of a support consisting of a plasticized cardboard plate or the like on which is applied by welding a transparent plastic sheet covering which is provided with a shell suitable for enclosing an article. In the art, such packaging is called a "blister".

Un autre emballage très courant, appelé "skinpack" de manière usuelle, est constitué par une plaque en carton généralement micro-perforé ou analogue sur laquelle on dispose au moins un article, puis une feuille de matière plastique souple transparente est placée au-dessus de l'ensemble précité et est appliquée sous vide sur celui-ci après chauffage. La feuille de recouvrement épouse alors exactement tous les contours de l'objet disposé sur le support et l'échauffement produit sa soudure sur ce dernier.Another very common packaging, usually called "skinpack", consists of a cardboard plate generally micro-perforated or the like on which there is at least one article, then a sheet of transparent flexible plastic material is placed on top of the aforementioned assembly and is applied under vacuum thereto after heating. The covering sheet then exactly matches all the contours of the object placed on the support and the heating produces its welding on the latter.

Dans les deux cas précédents, on constate une difficulté très importante à séparer le support et la feuille qui lui est associée malgré la présence habituelle d'un onglet situé dans un angle du support. Il est alors souvent nécessaire d'utiliser un objet contondant ou coupant pour avoir accès à l'objet emballé.In the two previous cases, there is a very significant difficulty in separating the support and the sheet associated with it despite the usual presence of a tab located in a corner of the support. It is then often necessary to use a blunt or sharp object to gain access to the wrapped object.

Les perfectionnements qui font l'objet de la présente invention visent à remédier à ces inconvénients et à permettre la réalisation d'un système facilitant la séparation des deux éléments d'un emballage présentant une structure telle que définie ci-dessus.The improvements which are the subject of the present invention aim to remedy these drawbacks and to allow the production of a system facilitating the separation of the two elements of a package having a structure as defined above.

A cet effet, la feuille de recouvrement est munie à proximité de son arête périphérique d'au moins une excroissance se dressant en saillie vers l'extérieur à partir du support et délimitant un volume de gaz isolé de l'extérieur,l'écrasement de cette excroissance provoquant la création subséquente d'une patte de préhension permettant l'arrachage aisé de ladite feuille par rapport au support.To this end, the covering sheet is provided near its peripheral edge with at least one protrusion projecting outwards from the support and delimiting a volume of gas isolated from the outside, the crushing of this protuberance causing the subsequent creation of a gripping tab allowing easy tearing of said sheet relative to the support.

Lorsque l'emballage est du genre constitué d'une feuille comportant une coque propre à renfermer au moins un article, ladite feuille étant soudée au support au moyen d'un cordon périphérique, l'on prévoit préférablement de réaliser l'excroissance sous la forme d'un dôme ménagé dans cette feuille. Dans ces conditions, le dôme est alors entouré par deux branches du cordon de soudure, la section de la branche située entre le dôme et l'arête périphérique de la feuille étant de largeur inférieure à celle de l'autre branche, de manière que l'écrasement du dôme détruise la branche du cordon de soudure de plus faible section, c'est-à-dire celle qui se trouve à l'extérieur, de façon à constituer aisément la patte de préhension précitée.When the packaging is of the kind consisting of a sheet comprising a shell suitable for enclosing at least one article, said sheet being welded to the support by means of a peripheral cord, provision is preferably made for the protuberance in the form a dome in this sheet. Under these conditions, the dome is then surrounded by two branches of the weld bead, the section of the branch located between the dome and the peripheral edge of the sheet being of width less than that of the other branch, so that the crushing of the dome destroys the branch of the bead of weld of smaller section, that is to say that which is outside, so as to easily constitute the aforementioned grip tab.

Si l'emballage est réalisé par une feuille assemblée au support par mise sous vide après échauffement, l'excroissance est obtenue en insérant entre cette feuille et le support un organe volumineux dont la forme correspond à celle voulue pour l'excroissance.If the packaging is carried out by a sheet assembled to the support by evacuation after heating, the protuberance is obtained by inserting between this sheet and the support a bulky member whose shape corresponds to that desired for the protuberance.

Le dessin annexé, donné à titre d'exemple, permettra de mieux comprendre l'invention, les caractéristiques qu'elle présente et les avantages qu'elle est susceptible de procurer :The appended drawing, given by way of example, will allow a better understanding of the invention, the characteristics which it presents and the advantages which it is capable of providing:

Fig. 6 et 7 illustrent la découpe de la coque d'un emballage suivant fig. 1, à partir d'une excroissance.Fig. 6 and 7 illustrate the cutting of the shell of a package according to fig. 1, from a growth.

On a illustré en Fig. 1 un emballage comportant application des perfectionnements suivant l'invention et réalisé sous la forme d'un "blister", c'est-à-dire comprenant tout d'abord un support 1 réalisé sous la forme d'un panneau de carton plastifié ou de matière plastique. Il comprend aussi une feuille de recouvrement 2 pourvue d'une coque 2a dans laquelle on prévoit d'enfermer un article quelconque et d'un rebord 2b entourant la coque, disposé dans un même plan et destiné à être soudé sur le support 1. A cet effet et de manière bien connue en soi, la soudure est réalisée au moyen d'un cordon 2c formé au moyen d'une électrode de forme appropriée. Cette technique étant bien connue, on ne décrira pas plus la réalisation de l'emballage considéré.Illustrated in FIG. 1 a package comprising application of the improvements according to the invention and produced in the form of a "blister", that is to say comprising first of all a support 1 produced in the form of a panel of plasticized cardboard or of plastic. It also comprises a covering sheet 2 provided with a shell 2 a in which provision is made for enclosing any article and with a flange 2 b surrounding the shell, arranged in the same plane and intended to be welded to the support 1 To this end and in a manner well known per se, the welding is carried out by means of a bead 2 c formed by means of an electrode of suitable shape. Since this technique is well known, the production of the packaging in question will not be described any further.

Suivant l'invention et préalablement à la soudure de la feuille de recouvrement 2 par rapport au support 1, l'on réalise dans le rebord 2b une excroissance 2d, par exemple réalisée sous la forme d'un dôme, comme illustré en Fig. 2. Cette excroissance peut être réalisée en même temps que la coque, généralement par thermo-formage. On notera que la base du dôme est située dans un angle de l'entourage 2b et à faible distance de l'arête extérieure du rebord 2b.According to the invention and prior to the welding of the cover sheet 2 relative to the support 1, the flange 2 b is produced a protrusion 2 d , for example produced in the form of a dome, as illustrated in FIG. 2. This protuberance can be produced at the same time as the shell, generally by thermoforming. It will be noted that the base of the dome is located in an angle of the surround 2b and a short distance from the outer edge of the rim 2b .

Au niveau de l'excroissance ou dôme 2d, le cordon de soudure 2c se divise en deux branchés 2'c, 2"c, cette dernière entourant partiellement l'excroissance ou dôme 2d à l'extérieur, c'est-à-dire au voisinage immédiat de l'arête correspondante de l'angle de l'entourage 2b. L'autre branche 2'c contourne l'excroissance ou dôme 2d par l'intérieur. Conformément à l'invention, la section de la branche 2'c est plus importante que celle de la branche 2"c pour des raisons qu'on va mieux expliquer ci-dessous (voir Fig. 3).At the level of the protrusion or dome 2 d , the weld bead 2 c is divided into two branches 2 ′ c , 2 " c , the latter partially surrounding the protrusion or dome 2 d outside, that is to say that is to say in the immediate vicinity of the corresponding edge of the angle of the surround 2 b, the other branch 2 ′ c bypasses the protrusion or dome 2 d from the inside. of branch 2 ' c is more important than that of branch 2 " c for reasons which will be better explained below (see Fig. 3).

Le fonctionnement est le suivant :The operation is as follows:

Une fois l'emballage fabriqué et mis dans le commerce, l'utilisateur en prend possession et lorsqu'il désire avoir accès à l'article renfermé par la coque 2a, il lui suffit d'appuyer énergiquement sur le dôme 2d pour le faire éclater, de telle sorte que celui-ci constitue alors une patte de préhension permettant un arrachage aisé de la feuille 2 par rapport à la plaque 1. Il est évident que le volume intérieur de l'excroissance ou dôme 2d est isolé de l'extérieur, de telle sorte que son écrasement doit obligatoirement provoquer la destruction d'une des branches de la soudure 2c. Du fait que la branche 2"c présente une section bien inférieure à celle de la branche 2'c, l'écrasement du dôme 2d entraîne la destruction de cette branche 2"c se trouvant située vers l'extérieur, de telle sorte que pratiquement tout ce dôme constitue la patte de préhension précitée. Pour faciliter la séparation du dôme 2d du reste de l'entourage 2b, on peut ménager à la base du dôme 2d et le long de la branche 2"c une zone de moindre résistance 2'd assurant une rupture certaine du dôme au niveau de sa base le long de ladite branche 2"c lorsqu'il est écrasé.Once the packaging has been manufactured and put on the market, the user takes possession of it and when he wishes to have access to the article enclosed by the shell 2 a , he only has to press vigorously on the dome 2 d to burst, so that it then constitutes a gripping tab allowing easy tearing of the sheet 2 relative to the plate 1. It is obvious that the interior volume of the protrusion or dome 2 d is isolated from the exterior, so that its crushing must necessarily destroy one of the branches of the weld 2 c . Because the branch 2 " c has a much smaller cross-section than that of the branch 2 ' c , the crushing of the dome 2 d causes the destruction of this branch 2" c being located towards the outside, so that practically all of this dome constitutes the aforementioned grip tab. To facilitate the separation of the dome 2 d from the rest of the surround 2 b , it is possible to provide at the base of the dome 2 d and along the branch 2 " c a zone of least resistance 2 ' d ensuring a certain rupture of the dome at its base along said branch 2 " c when it is crushed.

Au cas où la hauteur de la coque 2a serait inférieure à celle du dôme 2d (Fig. 4), on peut prévoir de réaliser un dôme 2d sur au moins trois zones de l'entourage 2d de manière que leurs sommets déterminent un plan sur lequel peut reposer un autre emballage de même type. Le plan en question est avantageusement, mais non exclusivement, parallèle à celui de la plaque 1.If the height of the shell 2 a is less than that of the dome 2 d (Fig. 4), provision can be made to make a dome 2 d on at least three areas of the surround 2 d so that their vertices determine a plan on which another packaging of the same type can rest. The plane in question is advantageously, but not exclusively, parallel to that of the plate 1.

Dans le cas où l'emballage est réalisé sous la forme d'un "skinpack", c'est-à-dire au moyen d'une feuille 2 souple non pré-formée, on obtient la formation de l'excroissance 2d en posant avant application de la feuille 2 par le vide sur le support 1, un organe volumineux sécable 3 (Fig. 5) ou similaire qui serait fragmenté ou détruit ou aplati lors de l'écrasement de l'excroissance 2d réalisée grâce à la présence de cet organe 3. L'écrasement de cette excroissance provoque également la constitution d'une patte de préhension permettant de séparer la feuille 2 par rapport au support 1.In the case where the packaging is produced in the form of a "skinpack", that is to say by means of a flexible sheet 2 not pre-formed, the formation of the protrusion 2 d is obtained by placing, before application of the sheet 2 by vacuum on the support 1, a bulky breakable organ 3 (Fig. 5) or the like which would be fragmented or destroyed or flattened during crushing of the protrusion 2 d produced thanks to the presence of this member 3. The crushing of this protrusion also causes the constitution of a gripping tab making it possible to separate the sheet 2 relative to the support 1.

On a ainsi réalisé un emballage composé de deux éléments, soit un support et une feuille de recouvrement, muni d'un système facilitant de manière très appréciable la séparation de ses deux éléments.A packaging composed of two elements was thus produced, namely a support and a covering sheet, provided with a system which greatly facilitates the separation of its two elements.

Dans le mode d'exécution suivant fig. 6, la coque 2a comporte une prédécoupe 2e du genre de celle 2'd prévue sur l'excroissance 2d. La prédécoupe 2e s'étend depuis l'excroissance 2d jusqu'à l'arête périphérique du rebord 2b. Cette prédécoupe s'étend en gros parallèlement à la face supérieure de la coque, c'est-à-dire celle qui est orientée vers la fente 1a de suspension de l'emballage. Ainsi, après éclatement de l'excroissance, il est possible d'arracher une partie de la coque, le reste de celle-ci formant une boîte qui peut être suspendue ou posée.In the following embodiment fig. 6, the shell 2 a has a pre-cut 2 e of the kind of that 2 ′ d provided on the protrusion 2 d . The pre-cut 2e extends from the protrusion 2 d to the peripheral edge of the rim 2 b . The precut extends roughly parallel to the upper face of the shell, that is to say the one that is directed toward the slot 1 a suspension of the package. Thus, after the protuberance has burst, it is possible to tear off part of the shell, the rest of the latter forming a box which can be suspended or placed.

Suivant une variante illustrée en fig. 7, la prédécoupe 2e de la coque 2a est une ligne partant de l'excroissance et y aboutissant pour délimiter une zone fermée 2f sur la coque. Après éclatement de l'excroissance, on arrache la zone 2f de la coque en vue de constituer un orifice de sortie de pièces contenues dans la coque, comme de la visserie, des bâtons de soudure, etc... l'emballage étant bien entendu suspendu ou posé pour constituer une espèce de boîte distributrice.According to a variant illustrated in FIG. 7, the pre-cut 2 e of the shell 2 a is a line starting from the protuberance and ending therein to delimit a closed area 2 f on the shell. After the protuberance has burst, zone 2 f is torn off from the shell in order to constitute an outlet orifice for parts contained in the shell, such as screws and bolts, welding rods, etc. The packaging being well heard suspended or posed to constitute a sort of distribution box.

Il doit d'ailleurs être entendu que la description qui précède n'a été donnée qu'à titre d'exemple et qu'elle ne limite nullement le domaine de l'invention dont on ne sortirait pas en remplaçant les détails d'exécution décrits par tous autres équivalents. En particulier il va de soi que l'on pourrait prévoir une multiplicité d'excroissances 2d ou dômes, destinées à constituer une décoration, et que les excroissances 2d pourraient affecter n'importe quelle forme géométrique quel que soit leur nombre et/ou leur hauteur.It should moreover be understood that the foregoing description has been given only by way of example and that it in no way limits the field of the invention from which one would not depart by replacing the execution details described by all other equivalents. In particular, it goes without saying that a multiplicity of 2 d outgrowths or domes could be provided, intended to constitute a decoration, and that the 2 d outgrowths could affect any geometric shape whatever their number and / or their height.
