Description

The Invention relates to an insulation for attachment to packaging, containers Bottles and / or flat bodies according to the generic term of claim 1

insulations serve to objects, liquids or gases and their containers shield from external influences. Such shielding generally aims to maintain or improving the shielded material. Essential external influences that are suitable for changing material properties, i.a. Heat as well electromagnetic radiation in the form of heat or light.

While a shielded or to be protected Material in front of light by means of an enveloping dark sheath or panel is relatively easy to shield, there is a greater problem when shielding a material from heat, as this except through Convection is also transmitted by radiation and heat conduction.

In All rule is for thermal insulation a foam enclosing the object to be shielded or a foil used with air chambers, which optionally with a reflective Layer is provided.

This is suggested by the German Utility Model DE 201 03 332 U1 a container for receiving tire sealant before, the container wall is surrounded with an insulation and / or a thermal foil. The insulation there consists of a foam, of films with air chambers or of polystyrene and of a thermal film.

The Thermofoil is with a reflective outer and / or inner coating Mistake. The insulation and the thermal film are formed in two parts, wherein the insulation can be provided within the thermal film.

adversely in this embodiment is the outside Attachment of the thermal foil. The reflective coating is either on the outside directed and / or on the inward outer layer intended. The reflective layer consists of an aluminum coating. Problematic in this embodiment is that the Aluminum coating has no protection against mechanical influences, such as protects against abrasion. This has the consequence that the aluminum coating in use damage is suspended, whereby an optimal thermal insulation is no longer possible.

Of Another is the attachment, such as a product marking on an aluminum coating without any damage of their functionality not possible, since this affects the reflective surface; that is to say dark or matte motifs is the reflective property at least partially, but usually completely eliminated and thus the functionality the thermal film affects: Heat conduction through the film passes through.

In US 2001/00 38 014 A1 is a receiving cup for the ground a container body described one in the container fluid in front of heat to protect. The insulation of the receiving cup consists of an internal reflective layer and an outer foamed layer. The local Isolation has some basic disadvantages, for example founded in it are that the Reflection layer is located at the innermost to the container, the front Heat are protected should. Thus, however, the reflective layer is unable to Radiation incident from the environment to reflect, since this first on the foamed Layer hits. These are heated progressively increasing over time, which is due to the close together lying layers a heat conduction is made possible by the reflective layer in the container body. Furthermore is the outside foamed layer sensitive to pressure and settles, for example, when lifting the local item, squeezing, whereby However, the insulation performance of the foamed layer decreases seriously.

Another container is in the US 5,223,513 A described. The local container is equipped with a label, which, however, has no insulating properties.

The Object of the present invention is to avoid the mentioned disadvantages insulation for attachment to packaging, containers Bottles and / or flat bodies to disposal to provide, on the one hand compared to conventional insulation improved Thermal insulation, as well as the possibility provides for the attachment of a product marking, without thereby affecting the thermal insulation impaired becomes.

These Task is solved by an insulation according to claim 1.

In particular, the object is achieved by an insulation for attachment to packaging, containers, bottles and / or sheet-like bodies, wherein the insulation consists of at least the following: a foamed layer, an adhesive layer, a reflective layer, a carrier layer and a printable layer and / or optionally a print layer.

According to one The basic idea of the invention is the layers in the order their list from the inside to the outside on a body to be shielded appropriate.

The foamed Layer here forms an excellent barrier against heat conduction. On this foamed Layer is a reflection layer with the help of an adhesive layer applied. On this there is a carrier layer. A printing layer according to the invention is on this carrier layer arranged.

According to one embodiment the individual layers are homogeneously formed and cover each other in a likewise homogeneous manner, so that the reflection layer is uniform on their outside of a carrier layer or a printable layer is covered. Thus, none occur heat sinks which, as in the prior art, would cause heat to pass through the metal layer is passed through. The carrier layer and / or the printable layer is preferably one of these bright or transparent material, so that a reflection of electromagnetic radiation in the direction of the material to be shielded opposite side of the insulation is easily possible.

The Printable layer according to the invention on the carrier layer arranged and thus is not in direct contact with the Reflection layer according to the invention as a metal layer, in particular as a metal foil, or as a metallized film is formed. One direct heat transfer of dark heat absorbing Areas on the metal layer is therefore not possible. The Problem of heat conduction from such gently warming ones dark spots through the metal layer is thus with the Insulation according to the invention given.

One Another advantage of the insulation according to the invention is that the printable layer according to the printing technique applicable to them is trained. The surface the printing layer is in this case adapted to the respective printing technique, i. the surface the print layer is built up or smooth, absorbent, hydrophilic or hydrophobic, depending on how a label or a Printing on the print layer to be attached.

According to one particularly preferred embodiment invention, the print layer is already finished with a label provided formed or even represents such a. The printing layer can in this case on the inner side of a film, which on the backing is applied. This has the advantage that a motive not to the outermost, but below an outer film layer is present and thus against external, in particular mechanical damage protected is. Therefor suitable films are preferably transparent or pastel colors translucent. These slides can be both one-sided and two-sided printable.

According to one basic inventive idea the reflection layer is arranged between two adjacent layers. hereby Two advantages are ensured. One is the reflection layer against external damage protected. Secondly, this arrangement according to the invention ensures that that no Heat or cold sink present directly on the reflective layer, which is a heat or cold break favor could. A reflection, especially of radiant heat, is both in direction the inside as well as the outside the insulation unhindered possible. If a pressure on the metal layer is to take place, it is on to pay attention that the printing materials used for thermal radiation are transparent, allowing heating of the print layer substantially is excluded.

by virtue of the arrangement of the reflection layer between two adjacent layers is it about it out possible, the thickness of the reflective layer to a minimum in the lower micrometer range to a maximum of 0.2 mm, since these are not subject to mechanical stress must resist. A saving of material is the result.

According to one another embodiment The invention is the foamed Layer a foamed Polyolefin layer. Preferred materials here are polyethylene (PE), polypropylene (PP) and polystyrene (PS). These materials are suitable otherwise in not foamed Version also as a carrier layer. Furthermore come as materials, in particular for the carrier layer, polyethylene terephthalate (PET) as well as polycarbonate in question.

According to one preferred embodiment of Invention is the layer thickness of the foamed Layer 0.2 mm to 2 mm, preferably 0.5 mm to 1 mm. This layer however, may also have a greater layer thickness as needed. It comes here decisively to the temperature difference on the two sides of the insulation, i. usually inside and outside the insulation should be maintained.

According to a further embodiment of the invention, the insulation on the side facing the shielding body with a selbstkle benden device or layer provided, so that the insulation, optionally after a detachment of a protective strip by simply pressing on a package, a container and / or a flat body can be attached.

In summary let yourself hold that the insulation according to the invention is ideal, for example, bottles, cans, boxes or other packaging bodies to envelop and these against heat and against electromagnetic radiation in the form of heat and due to the inventively provided Shield reflection layer against light. The isolation of the invention can due to their preferably very thin design, the total thickness in the Range of 0.2 mm to 5 mm, but preferably in the range of 0.5 mm to 2 mm or less, on commodities such as for example, be mounted on bottles and a heat transfer from the inside to the outside or vice versa effectively prevent. Due to the inventively provided Print layer, which can either act as a label itself and / or is printable, the isolation of the invention is also suitable excellent for simultaneous insulating product labeling. Aptitude for the isolation of beverage bottles and beverage cans or other heat or cold-sensitive Liquids, gases or solids is the isolation of the invention thus inherent and especially advantageous.
