Definitions

  • the present invention relates to a packaging made of thermoformable material comprising a location intended to receive and maintain a product such as for example an informative label.
  • thermoformable sheet materials makes it possible to obtain packaging which conforms well to the shape of the objects and to provide either large-opening shells which must then be fixed on a cardboard, or complete packaging which can be closed by articulation of two cooperating parts around a hinge connection.
  • the presentation of the article must be supplemented by labeling which helps the sale by providing information not directly visible such as for example a composition, suggestions for use or the price of the product.
  • this information can be carried by a cardboard support on which the blister is welded, on a label stuck on the blister or on a label placed inside the blister and visible through the sheet matter.
  • This last labeling method is the most widely used because it allows on the one hand to use a non-adhesive label, therefore less expensive, and on the other hand to obtain a tamper-proof labeling since it is inside sealed packaging.
  • Such an arrangement requires that the size of the label coincides with the dimension of the front face of the blister so that the positioning is stable and adjusted. It follows an imposed size of the labeling which is not always in correspondence with the volume of information to be communicated and which can hide the article presented, thus losing the benefit of the transparent wall.
  • the object of the present invention is to propose a new blister-type packaging in which a space is provided, in particular for a non-adhesive label, regardless of the size of the front face of the shell and / or of the packaged product.
  • thermoformed blister there is provided in the front face of the shell of the thermoformed blister a cavity or hollow zone provided with gadroons undercut capable of retaining, in a preferred application, a label of dimension adapted to the cavity at the bottom of this one.
  • the blister which can be in the form of a shell simple to weld on a bottom or in the form of a double shell reclosable on itself around a hinge, is produced from a sheet of thermoformable material such as for example PVC, PET or polystyrene, in which a hollow area is provided, the side wall of which is provided with undercut gadroons, located near for example the bottom wall of said area hollow.
  • a sheet of thermoformable material such as for example PVC, PET or polystyrene
  • a hollow area is provided, the side wall of which is provided with undercut gadroons, located near for example the bottom wall of said area hollow.
  • the bottom of the hollow area which may be in the form of a cavity is slightly curved, so as to provide the elasticity necessary for the steps of manufacturing the blister, then placing the label.
  • the shape of the cavity is dependent on the shape chosen for the label and may be circular, oval or polygonal or any other regular shape or not.
  • at least two gadroons or lugs are formed on the side walls of the cavity, near the bottom, which have the function of keeping the label pressed against the bottom of the cavity. These pins are placed in opposition so that the label is maintained correctly.
  • the distance between each gadroon and the bottom of the cavity must be slightly greater than the thickness of the label and the height of each gadroon is such that the distance between the top of two facing gadroons is significantly less than the corresponding width of the label.
  • a cavity is provided, the bottom of which is the same dimension as the label and the gadroons of which have a height of between 0.3 and 0.6 mm. Indeed, such dimensions are both sufficient to ensure the maintaining the label and compatible with manufacturing requirements. Furthermore, it is recommended to form the bottom in a slightly convex manner (that is to say curved towards the outside of the cavity): this arrangement has the advantage of slightly increasing the elasticity of the cavity and, by Consequently, to facilitate the exit from the thermoforming mold and the fitting of the label. In order to ensure easy positioning of the label as well as good stability thereof in the cavity, it is preferable to use a label having an average rigidity, of the Bristol type for example.
  • the material for producing the label is generally a light paper or cardboard, but any other known material can be used, for example printable plastic films.
  • the packaging shown in Figure 1, is made from a thermoformable material and comprises a shell 1 surrounded by a flange 2.
  • the shell 1 comprises a zone in hollow in cavity 3 in which is provided at least one godron 4 undercut and located at a certain distance from the bottom 5 of the hollow area 3 so as to be able for example to have an informative label 6, between the bottom 5 and the godron 4.
  • the hollow zone 3 which is in the form of a cavity, comprises on its inner periphery 12 two gadroons facing one another and, preferably, four gadroons 4 arranged in a cross, one of which 4 'is more pronounced in order to prevent rotation of the label 6 (FIG. 2).
  • Figure 3 is a cross section of the blister shell according to III-III. We can see the main shell 1, the cavity 3 intended to receive the label 6 and the gadroons 4.
  • FIG. 4 is a detail of FIG. 3 showing the cavity 3 provided with the gadroons 4 whose bottom 5 is convex and with the label (5) held between the bottom 5 and the gadroons 4.
  • the gadroons 4 are in the general form of an S with two adjacent parts 7 and 8 forming a certain angle between them, which allows easier insertion of the label 6 in the housing 9 formed between the bottom 5 and the gadroons 4.
  • a PVC film 400 ⁇ m thick, transparent is used, usually used for thermoforming blisters.
  • the shell is thermoformed by penetration of an imprint through a preforming frame.
  • the male imprint represented by FIG. 5, which in the usual way is in the exact shape of the hull, has undercuts 10 of approximately 0.5 mm in depth and at the bottom of each it arrives from the conduits 11 which can be placed under vacuum at the time of thermoforming. This depression presses the flexible film on the walls of the cavity and in particular at the bottom of each of these remains 10 to form as many gadroons on the internal periphery of the shell 1.
  • a label which is, in this example, lightly cardboard paper which is of dimensions equal to that of cavity 3 and this label is slipped to the bottom of said cavity. A slight pressure allows it to pass behind all the gadroons where it then remains trapped. It should be noted that the convexity of the bottom of the cavity allows elastic deformation of the label which facilitates its positioning.
  • the blister is used in the usual way until the end of packaging.
  • the cavity 3 can be re-entrant as shown in FIG. 6.
  • This arrangement is particularly well suited to the presentation of articles in the form of rolls, the label then finding place in the support tube.
  • the label which is placed on the outside of the blister, can be applied after the end of packaging of the product and, in particular, just before shipment.
  • the label being visible directly, it is possible to use a non-transparent thermoformable material or a moldable material such as cardboard.
  • Another variant consists in forming the cavity according to the embodiment described above to obtain the label inside the packaging, and cutting a window in a part of the bottom of the cavity so as to reveal the label. through this window without the need to use a transparent material to thermoform the blister.
  • This new type of blister finds its application whenever it is important to provide information for a packaged item: manufactured items, food products, DIY accessories or household accessories.
  • a transparent PET film and a cardboard label makes it possible to obtain incinerable packaging; similarly, the use of a stamped cardboard packaging and a paper label does not require any adhesive and provides totally and quickly biodegradable packaging.
  • Another advantage of the blister pack according to the invention is to provide packaging that is generally less expensive than known packaging.
  • blister-type packaging allows the insertion of an informative label, depending on the country of destination of the packaged product. Indeed, the labels which are manufactured separately and written in different languages, are introduced at the time of the packaging of the products. This avoids manufacturing and storage of previously printed packaging and / or products on which information is affixed in several languages.
