THE BASIS OF THE INVENTION

Field of the Invention [0002] In general, the invention relates to labeled containers, in particular to containers labeled in the form and to methods for producing in-molded containers, which limit oxygen permeability to containers.

Description of Related State of the Art [0003] Methods for attaching labels to containers, including plastic containers, are known in the art. For example, those skilled in the art are familiar with the methods of applying the adhesive to the underside of the labels and then sticking the labels on the plastic containers. Labeling in containers also uses in-mold labeled (IML) methods. For example, US20100001010A1 discloses a container labeled in a mold and forming method to form a container. US5604006 discloses a method of labeling in a form which consists in the label being glued to a thermoplastic substrate in a mold cavity and injecting a molten thermoplastic resin by pressing the label and sinking it into a thermoplastic substrate. US4913643 discloses a plastic mold suitable for labeling in a mold. The result is a plastic container with an integrated label. Plastic containers made using IML methods can be used for various purposes, e.g. container for various food products, beverages, etc.

[0004] For example, US2008 / 0069990 A1 relates to an injection molded article comprising HDPE having a density of more than 930 kg / m.³ and at least one in-mold label.

[0005] Hereinafter, WO2009 / 007453A1 relates to a packaging article for containing and holding food products, which article includes barrier means for limiting the oxygen permeability of an article and into one or more compartments, wherein the packaging article comprises an oxygen scavenging agent, which together with the second plastic material it is introduced into the cavity of the first plastic material forming the walls, the bottom (bottom) and the cover (s) of the packaging article, the first plastic material being suitable for contact with food products. In addition, a method is described for producing a package finished in one injection molding cycle comprising three process steps: - A barrier film with or without decoration is placed in a mold. - The first plastic material suitable for contact with food products is injected into a closed mold, where the barrier film is placed. At this stage, the mold is partially filled. - The second plastic material, containing an oxygen scavenger, is injected into the mold until it is filled, so that the oxygen scavenger is surrounded by the first plastic material suitable for contact with food products. [0006] Further, US2009 / 0169902A1 relates to an oxygen absorbing resin composition comprising a thermoplastic resin that has carbon-carbon double bonds substantially only in the main chain and a transition metal salt, wherein the amount of oxygen absorbed is 1.6 moles or more per mole of double carbon-carbon bonds in a thermoplastic resin. where the barrier film is placed. At this stage, the mold is partially filled. - The second plastic material, containing an oxygen scavenger, is injected into the mold until it is filled, so that the oxygen scavenger is surrounded by the first plastic material suitable for contact with food products. [0006] Further, US2009 / 0169902A1 relates to an oxygen absorbing resin composition comprising a thermoplastic resin that has carbon-carbon double bonds substantially only in the main chain and a transition metal salt, wherein the amount of oxygen absorbed is 1.6 moles or more per mole of double carbon-carbon bonds in a thermoplastic resin. where the barrier film is placed. At this stage, the mold is partially filled. - The second plastic material, containing an oxygen scavenger, is injected into the mold until it is filled, so that the oxygen scavenger is surrounded by the first plastic material suitable for contact with food products. [0006] Further, US2009 / 0169902A1 relates to an oxygen absorbing resin composition comprising a thermoplastic resin that has carbon-carbon double bonds substantially only in the main chain and a transition metal salt, wherein the amount of oxygen absorbed is 1.6 moles or more per mole of double carbon-carbon bonds in a thermoplastic resin. thanks to which the oxygen scavenger is surrounded by the first plastic material suitable for contact with food products. [0006] Further, US2009 / 0169902A1 relates to an oxygen absorbing resin composition comprising a thermoplastic resin that has carbon-carbon double bonds substantially only in the main chain and a transition metal salt, wherein the amount of oxygen absorbed is 1.6 moles or more per mole of double carbon-carbon bonds in a thermoplastic resin. thanks to which the oxygen scavenger is surrounded by the first plastic material suitable for contact with food products. [0006] Further, US2009 / 0169902A1 relates to an oxygen absorbing resin composition comprising a thermoplastic resin that has carbon-carbon double bonds substantially only in the main chain and a transition metal salt, wherein the amount of oxygen absorbed is 1.6 moles or more per mole of double carbon-carbon bonds in a thermoplastic resin.

Further, JP2004155483 relates to a plastic container laminated during molding, so that the in-mold label is made of sandwich materials consisting of at least a layer of a transparent resin deposited from the gas phase of a thin layer of silicon oxide, alumina, oxide

Magnesium oxide or mixtures thereof, an oriented film layer, an oxygen absorbing layer consisting of 30-70 wt.% Mixtures. an oxygen absorber mainly consisting of an ionic powder mixed with 70-30 wt% a thermoplastic resin, wherein the thermoplastic resin layer forms the inner surface of the main resin layer in the container, and the transparent resin layer of the in-mold label forms the main side layer of the resin. The entire inner surface of the container is covered with an in-mold label and the innermost surface of the container is made of a thermoplastic resin layer.

[0008] Furthermore, JP2002120848 relates to a plastic container that has recesses on the surface and a label comprising a gas barrier layer and an oxygen absorbing resin layer that is within the gas barrier resin layer, which label is adhered to the container, so that it covers at least the entirety of the recesses formed in the surface of the container.

[0009] Further, US2009 / 0061061 A1 relates to a multilayer film that has a multi-layer active oxygen barrier comprising at least one 1) active oxygen barrier layer between two passive oxygen barrier layers or 2) a passive oxygen barrier layer between oxygen two active oxygen barrier layers. In addition, the active barrier layer may comprise a composition that is a mixture of a thermoplastic resin with carbon-carbon double bonds substantially in its main chain, a transition metal salt and an oxygen barrier polymer. Further, the active barrier layer may also contain a compatibilizer. The passive oxygen barrier layer helps to maintain the oxygen barrier properties of the multilayer film,

[0010] Furthermore, US2005 / 0079306 A1 relates to a thermoplastic resin composition comprising an oxygen scavenger in which the resin matrix in this thermoplastic resin composition is substantially incompatible and is composed of a blend of thermoplastic resins or elastomers, where incompatible thermoplastic resins or elastomers are present as a heterogeneously distributed structure in a matrix of resin. The packaging container or lid inhibits the reduction of odor retention in the event that the absorbent or its oxidation product is rinsed, even after sterilization in the retort. You can get content protection and preserve the fragrance for a long time. In addition, the rate of oxygen absorption can be increased.

[0011] Some food products and other articles must be insulated in the container so that they do not react with oxygen in the environment. One way to prevent this interaction is to incorporate an oxygen barrier into the container design. For example, Japanese registered utility model No. 3024995 discloses a container in which a label that has an oxygen barrier property is connected to the outer wall of the container. US7608340 discloses a container comprising a layer that includes an oxygen absorbing resin comprising a copolymer of ethylene and vinyl alcohol (EVOH) and an oxygen absorber. Similarly, US7588157 discloses an IML container in which a label including a barrier layer comprising EVOH is used to give the label oxygen barrier properties. In addition, many products must be packaged in containers,

[0012] However, the labels currently used to make IML containers are relatively thin, because the oxygen barrier layer can not be thick when it is made by available spsobami. As a result, the oxygen barrier property of such IML containers is insufficient to maintain oxygen outside the container. In addition, moisture barrier and relatively high temperatures are adversely affected by the oxygen barrier properties of these labels. Accordingly, known IML containers made using these labels are not

EP 2 590 791 may be used when the products have to be sterilized. There is therefore a need for new containers

IMLs that have good barrier properties to oxygen and which can, if necessary, be sterilized.

SUMMARY OF THE INVENTION [0013] The object of the invention is therefore to provide methods of making containers labeled in a mold that have an oxygen barrier.

[0014] Another object of the invention is to provide containers that are labeled in a mold that have an oxygen barrier.

[0015] Another object of the invention is to provide containers that are labeled in a mold that have an oxygen barrier and that can be sterilized in the retort.

[0016] One or more of these or other objects can be achieved using new methods of making containers labeled in the mold. Such methods include laying in the form of a multi-layered label that has a barrier layer for oxygen and injection of a molten resin suitable for forming the container. In this process, a container with a barrier layer against oxygen is produced. In preferred embodiments, the multilayer label has at least one layer of an oxygen absorbing resin comprising an ethylene-vinyl alcohol copolymer and an oxygen absorber.

[0017] Other and further objects, features and advantages of the present invention will be readily appreciated by specialists.

BRIEF DESCRIPTION OF THE DRAWINGS [0018]

FIG. 1 illustrates an embodiment of the invention and shows the construction of an IML barrier label comprising an oxygen scavenger.

FIG. 2 illustrates a known shrink wrap wrapper used on containers.

FIG. 3 illustrates the well-known in-mold label.

DETAILED DESCRIPTION OF THE INVENTION

Definitions [0019] The term "multi-layered label having (or including) (at least) an oxygen-absorbing resin layer" refers to a label having a plurality of layers, at least one of which is an oxygen-absorbing resin layer. This label also contains the company sign (s), such as lettering, letter symbols, patterns, markings, etc. visible on the label itself, and preferably visible when inserted into a labeled container in the form. Such a sign (i) may be given by a printing ink, etc. When a sign or signs are not present, such a structure is referred to as a "multilayer sheet having at least an oxygen absorbing resin layer".

[0020] The term "layer" refers to a single, discrete, thickness of material that is uniform in composition compared to the material (s) adhering to it (ie, in contact with it) and / or separately applied / formed, or may refer to, essentially, a series of sublayers that are consecutively in contact with each other, which together may provide a particular function. In the following description, both meanings of the term "layer" appear.

In one aspect, the invention provides a labeled container comprising: a multilayer label comprising an oxygen absorbing resin layer and a resin container body wherein the multi-layered label covers all or part of the outer or inner container surface and the oxygen absorbing resin layer is a sublayer in a multi-layer barrier layer to oxygen, wherein the multilayer oxygen barrier layer further comprises at least one oxygen barrier resin sublayer, and wherein the total thickness of one or more

EP 2 590 791 of the optional layers located outside of the multilayer oxygen barrier layer is denoted by X, and the total thickness of the container is determined by Y, and the ratio X / Y is from about 0.01 to about 0.25.

In another aspect, the invention provides a method of making a container labeled in a form comprising: arranging a multi-layered label having an oxygen barrier layer adhered to the mold body and injecting the molten resin into the mold, the label remaining between the mold body and the molten resin and forming thus a container in which the total thickness of one or more optional layers located outside the multi-layer oxygen barrier layer is determined by X, and the total thickness of the container is determined by Y, and the ratio X / Y is from about 0.01 to about 0.25.

[0022] Further embodiments of the present invention are described in the dependent claims.

[0023] FIG. 2 and FIG. 3, when compared with FIG. 1, illustrate the differences between known labels and containers as well as labels and containers according to the invention. The label in FIG. 2 is typically used with containers that are not sterilized in retorts, for products such as drinks. Construction of containers of this type are shown in FIG. 3. In general, these labels do not completely surround the container. In addition, IMLs with such a structure are not immune to withstand sterilization in the retort. In contrast, the container according to the invention can be sterilized in the retort.

[0024] In one embodiment, the IML structure shown in FIG. 1 is imprinted. Thus, to form a container according to the invention in a mold, an IML label with an imprint is placed. Then, the polypropylene body is made in the same form in such a way that the container body is completely surrounded (sides and bottom) by the IML which is embedded thereon. A sectional drawing showing the container and IML layers is visible in FIG. 1. A double layer of EVOH together with the container body structure confers strength to the required sterility. The oxygen scavenging layer and the light barrier thanks to IML inks ensured stability of the product for oxidation during its entire lifetime. After the container of IML has been made, it is filled, sealed and subjected to sterilization in a retort as described herein. The difference is that the label is now part of the container;

Thus, according to the invention, there are provided methods of making containers labeled in a form having unique oxygen barrier properties, preferably containers that can be sterilized.

[0026] In another aspect, the invention provides containers labeled in the form produced by the methods of the invention.

[0027] The methods and containers of the invention limit the amount of oxygen that enters the container in a given period. This restriction prevents the container from degrading the oxygen content and extends the life of the product.

[0028] The invention is not limited to the specific methodology, protocols and reagents described herein, because they can be varied. In addition, terminology is used herein to describe only specific embodiments and not to limit the scope of the present invention.

[0029] As used herein, the ranges are given in brief to avoid mentioning and describing everywhere anywhere in the range. The appropriate value in the range can be selected, if necessary, as the upper value, lower value or range limit.

Then 0.0424 parts by weight of [1,3-bis (2,4,6-trimethylphenyl) -2-imidazolidinylidene] dichloro (phenylmethylene) (tricyclohexylphosphino) ruthenium was dissolved in 3 parts by weight of toluene to form a catalytic fluid. This catalytic fluid was rapidly charged into a three-necked flask and the solution was stirred at 55 ° C to perform ring-opening metathesis polymerization. After 1 hour, the reaction liquid was analyzed by gas chromatography (GC14B, manufactured by Shimadzu Corp .; column: G-100 produced by Chemicals Evaluation and Research Institute, Japan). The result confirmed that there is no cis-cyclooctene. Then, 1.08 part by weight of ethyl vinyl ether was introduced into the three-necked flask and the further mixed liquid was stirred for 10 minutes.

[0034] 200 parts by weight of water were added to the produced reaction liquid, and the mixed liquid was stirred at 40 ° C for 30 minutes. The liquid was then allowed to stand still at 40 ° C for 1 hour to separate into liquid phases. The aqueous phase was then removed. 100 parts by weight of water was again added to the remaining liquid and the mixed liquid was stirred at 45 ° C for 30 minutes. The liquid was then allowed to stand still at 40 ° C for 1 hour to separate into liquid phases. The aqueous phase was then removed. The heptane was distilled off under reduced pressure from the remaining liquid. A vacuum dryer was used to dry the formed solid at 1 Pa and 100 ° C for 6 hours to obtain 102.1 parts by weight of polymer with a weight-average molecular weight (MW) of 14200, wherein the amount of oligomers having a molecular weight of 1000 or less was 9.2% (yield: 92%). In this polymer (polyacetylene), the ratio of carbon-carbon double bonds in the side chains to all carbon-carbon double bonds was 0%.

[0035] The produced polymer was broken into 1 mm pieces² and the pieces were placed in a separate flask equipped with a stirrer, reflux condenser and thermostat. Then, 300 parts by weight of acetone were introduced into the separate flask and the mixture was stirred at 40 ° C for 3 hours. Then acetone was removed by

EP 2 590 791 decanting. Once again, 300 parts by weight of acetone were introduced into the separate flask and the mixture was stirred at 40 ° C for 3 hours. The acetone was then removed by decanting. The remaining acetone was distilled off under reduced pressure. A vacuum dryer was used to dry the produced solid at 1 Pa and 100 ° C for 6 hours to obtain 99 parts by weight of a polyethylene glycol having a weight average molecular weight (Mw) of 150,000 and a number-average molecular weight of 37,000, in which the amount of oligomers having a molecular weight of 1000 or less was 3.1%.

The temperature was raised to 50 ° C and then 4.25 parts by volume of monomer - styrene was introduced to carry out the polymerization for 1.5 hours. The temperature was then reduced to 30 ° C and 120 parts by volume of isoprene was added and polymerization was carried out for 2.5 hours. Further, the temperature was again raised to 50 ° C and 4.25 parts by volume of the styrene monomer was introduced and the polymerization was carried out for 1.5 hours.

[0037] 2-tert-butyl-6- (3-tert-butyl-2-hydroxy-5-methylbenzyl) -4-methyl-phenylacrylate and tetrakis (3-laurylpropionate) pentaerythritol as antioxidants were added to the produced reaction liquid, in each of them 0.15 parts by weight per 100 parts by weight of the styrene and isoprene used. The reaction liquid was poured into methanol to precipitate the product. The product was separated and dried and a triblock styrene-isoprene-styrene copolymer to which antioxidants were added was obtained.

The number average molecular weight of the resulting triblock copolymer was 85,000 and the molecular weight of the styrene blocks in the copolymer was 8,500. The styrene content in the copolymer was 14 mole%, and the ratio of carbon-carbon double bonds in its side chains to all carbon double bonds the coal was 55%. The content of carbon-carbon double bonds in the produced triblock copolymer was 0.014 eq / g. The melt index was 7.7 g / 10 minutes. The resin contained 0.12% by weight of 2-tert-butyl-6- (3-tert-butyl-2-hydroxy-5-methylbenzyl) -4-methylphenyl acrylate and 0.12% by weight of pentaerythritol tetrakis (3-laurylpropionate).

The components were extruded at 210 ° C with a screw rotation speed of 100 rpm and a resin extrusion of 4 kg / hour, and pellets of the oxygen absorbing composition were obtained.

[0040] Next, the pellets of the oxygen absorbing composition, polypropylene (PP) (NOVATEC EA7A, manufactured by Japan Polypropylene Corp.) and adhesive resin (AD) (Admer QF500, manufactured by Mitsui Chemicals, Inc.) were separately melted and kneaded in separate extruders, and a coextruder was used to produce a multilayer label of 5 layers classified under 3 types (PP layer / AD layer / oxygen barrier layer (a layer) at a 220 ° C embossing temperature.

The cut multi-layered label was laid on the internal surfaces of the female part of the mold. Next, a male mold part was pushed into the female mold from the top, and the molten resin (polypropylene (NOVATEC EA7A)) was injected into the socket between the male and female forium sections at 220 ° C. In this way, injection arrest was carried out in order to hijack the IML. The thickness of the body of the gasifier was 700 μτ and the surface was 83 crn².
