Definitions

• the invention relates to a new seal whose essential feature is to be provided with a watermark.
• watermark denotes a drawing or an image that is observable or visible in transmitted light.
• observed or visible in transmitted light we mean of an element (here the watermark) that it is visible, in particular to the naked eye, when it is placed between the eye of the observer and a source luminous so that the eye perceives the rays of the light source through the observed element.
• the watermark is visible by transparency in visible light, that is to say at a wavelength between 380 and 780 nm.
• the watermarks are visible in transmitted light but they are not in reflection, that is to say when the eye of the observer and the light source are placed on the same side of the element to be observed. eye thus perceiving the rays of the light source reflecting on the observed element.
• the seal of the invention is of the type used for sealing consumer products, in particular in the food or cosmetic field.
• the one-piece seals consist of a foamed support or not.
• a foam it is made of polypropylene (PP), polyethylene (PE) or polyethylene terephthalate (PET) foams, optionally laminated with PP, PE or polyethylene terephthalate (PET) films.
• PP polypropylene
• PE polyethylene
• PET polyethylene terephthalate
• These seals have the function of sealing the packages vis-à-vis firstly the content, liquid or not, but also vis-à-vis the oxygen, as well as vis-à-vis the flavors and smells.
• These seals are generally delivered to the capsule or cap manufacturer. The manufacturer inserts them at the bottom of the capsule or corks and delivers them to the end customer.
• the invention also relates to double-piece gaskets intended to be glued or sealed on the rim of the container.
• These seals consist of two parts respectively a lid and a support.
• the lid is placed all around the upper rim of the neck of the container or drinking, thus isolating the container from the outside.
• the support is usually thicker. It is inserted, without being fixed, at the bottom of the cap. Prior to the first opening of the container, the support and the lid may be secured by means of a temporary adhesive.
• the bonding is carried out conventionally by means of an adhesive compatible with the rim and the underside of the cover.
• the seal When the seal is intended to be sealed on the container, it has a sealing layer applied on its underside. Sealing is done by induction heat sealing through the plug. This heat sealing is made possible by the combined action of a conductive material, inserted in the thickness preferably, of the lid, which, under the effect of the magnetic induction heats up, causing the softening of the film of sealing on the rim.
• the distribution circuit of these seals is identical to that set up and described previously for monobloc seals.
• the document US2003 / 0127846 describes an anti-counterfeiting device in the form of a crimping tab whose inner face is covered by an image appearing only in contact with oxygen . As the tab is removed, the image, including the brand of the drink, is revealed in contact with oxygen.
• the solution that is required is that of the seal marking with the effigy of the seal manufacturer.
• the constraint for the consumer product manufacturer is that it does not wish for its part that this marking is visible to the end consumer. Indeed, there is no interest in this being the case, besides the aesthetic aspect that could be affected.
• US3628271 describes capsules whose outer surface is covered with a layer revealing a date of expiry under UV light.
• US7789074 discloses a seal consisting of a compressible layer on which is applied a transparent film.
• the compressible layer is structured. It is in the form of a series of extruded filaments.
• the structure of the compressible layer is visible in reflection whatever the face of the joint so that it is not a watermark.
• the problem to be solved by the invention is to develop a seal provided with an identification means that is not visible to the consumer.
• the subject of the invention is a light-transmissive seal, in practice visible light intended in particular to be inserted at the bottom of a plug or capsule in the form of a medium which itself transmits light.
• light advantageously made of an expanded material on at least one of the faces of which is applied a material, referred to in the following description and in the claims by the term "coating" also transmitting light.
• This seal is characterized in that the face of the support on which the coating is applied and more specifically the coating itself, has a watermark, that is to say a visible image in transmitted light and not visible in reflection.
• the seal of the invention is a one-piece seal or the support part of a double-piece seal.
• a monobloc seal whether it is the capsule or cap manufacturer or the manufacturer of the final product, whether it receives the capsule + seal assembly or more rarely the seal directly, all can perfectly identify the source of the seal.
• the identification of the seal in practice of its support can be performed only after separation of the support relative to the lid.
• the material constituting the support is an expanded material which is preferably selected from the group consisting of low density polyethylene (PE), polypropylene (PP), PET, polystyrene (PS).
• the density of the foam is between 30 and 500 kg / m 3 , advantageously between 150 and 400 kg / m 3 , that is to say a medium density.
• the thickness of the foam is advantageously between 1 and 3 mm.
• the material constituting the support is an unexpanded material which is preferably selected from the group comprising polyethylene, polyethylene copolymers, thermoplastic elastomers, PP, PET, PS.
• the density of the support is in this case between 800 and 1500 kg / m 3 .
• the support is extruded, having regard to the nature of the materials used.
• the support is made of unexpanded, non-extruded material and transparent light. It may be for example density cardboard advantageously between 40 and 600 kg / m 3 .
• the light transmitting coating applied to the support comprises a sheet of paper and / or at least one polymer film.
• the light-transmitting coating comprises at least one polymeric film.
• the polymer film is chosen from the group comprising PET, PVDC, PP, polyester, PA (polyamide), PE (polyethylene).
• the film preferably has a thickness of between 5 and 100 micrometers.
• the light transmitting coating comprises 2 polymer films.
• the light transmitting material is a complex consisting of a polyester top film and a polyethylene bottom film.
• the 2 films once associated are then calendered or laminated on the support.
• the light-transmitting coating is applied to one or both sides of the extruded or non-extruded support.
• the watermark is applied to the face comprising the light transmitting coating.
• the seal can be positioned at the bottom of the capsule or cap in any direction.
• the shape of the joints of the invention will be determined according to the shape of the cap or the capsule.
• the light-transmitting coating has a watermark.
• This watermark can be obtained in different ways being recalled that by definition, it is a visible pattern in transmitted light.
• the light-transmissive coating is white in color and the expanded or non-foamed material is preferably also white in color.
• the watermark is in the form of a white print and is preferably applied to the back of the light-transmitting coating. Under these conditions, the coating is advantageously a polymer film.
• the watermark is applied between the support and the light-transmitting coating, in particular the film.
• the watermark that is to say a visible image in transmitted light and not visible in reflection is preferably applied to the back of the light-transmitting coating.
• a repetition of a white pattern of marked color is printed on a strip of white PET polymer film.
• the PET film has a thickness of 25 microns.
• This strip of film is laminated on an expanded strip of white PE.
• the foam has a thickness of 1 mm and a density of 200 kg / m 3 . In the thickness of the complex obtained, the joints are cut in the desired size.
