Description

EMOTIONAL PELLET LABEL FOR MIXED CONTAINERS FIELD OF THE INVENTION The present invention relates to mixed containers for food products, and more particularly, to removable one-piece film labels applied to the outer surface of mixed containers.

BACKGROUND OF THE INVENTION In the packaging of perishable food products, a container that is rigid enough to maintain its shape when subjected to internal pressure produced in the container while sealing the food product to protect it against rust, against spills, and contamination is required. . In this way, perishable food products are often packaged in mixed tubular containers that are sealed at both ends. In particular, chilled dough products are typically packaged in spirally wound containers that allow access to dough products by unwinding the spiral seam. These containers depend mainly on the label to provide sufficient strength to retain the pressurized contents of the package (A, you until consumers use the product.) The consumer detaches the label from the package, allowing to open the container along the spiral seam, revealing the dough product.The tubular portion of these containers conventionally includes three Separate sheets or groups of sheets First, there is included at least one structural body sheet made of cardboard, which is formed into a tubular structure by winding a continuous strip of body sheet cardboard around a forming mandrel. of the body sheet may be wound in a spiral around the mandrel or passed through a series of forming elements to wind in a convoluted shape around the mandrel The tube is subsequently cut into predetermined lengths at the downstream end of the mandrel. and fits with the end closures to complete the container.Second, these containers typically include a sheet of coating impermeable to liquid adhering to the inner surface of the sheet of the cardboard body. The coating sheet seals the food product, such as dough, inside the container and also prevents liquids from entering the container, which may possibly contaminate the food product. Some coating sheets are also impermeable to gas, to not only prevent the odors of the food product from escaping from the can, but also to prevent air from entering the container and spoiling the food product. In this way, while the purpose of the body sheet is to provide necessary structural properties for the container, the coating sheet provides barrier properties necessary to protect and maintain the perishable food product. Finally, a label sheet, which is typically a paper-based sheet, is included and adhered to the outer surface of the sheet of the cardboard body. The label sheet has two main functions. First, a mixed can label is a source of information. The label carries the graphic material that conveys the information, instructions, and compliance information of product rules. The label is also preferably decorative and aesthetic to the consumer, which improves the appearance on the shelf and increases consumer interest in the food product. Charts included in conventional paper labels are also rotogravoured or flexographically printed and, to protect the inks used in the label printing process, lacquers may be required on the inks. However, the lacquers are not completely absorbed in the paper and thus create labels that have a poor aesthetic appearance. The second function of the label sheet is to provide some physical characteristics to the mixed can. The coefficient of friction of the label sheet is important since the lower the coefficient of friction, the handling of the mixed container is greater. The container is often routed along conveyor lines and conduits while it is manufactured, filled and then shipped. In this way, a mixed container with a high coefficient of friction can create inefficiencies in the packaging of the product and increase the cost of packaging the food product, while a container with a low coefficient of friction can minimize such inefficiencies and costs. Also, the moisture resistance of the label sheet can be an important factor in the design of the mixed container. If the container is exposed to moisture and if the sheet of the cardboard body is moistened, the resistance of the can is compromised. This humidity is sometimes found during storage and shipping. Other times, condensation may form on the surface of the can if the can is cooled or otherwise exposed to elevated temperatures and then moved to a hot, humid environment. If the moisture resistance of the label sheet is low, then the label will provide a small additional protection to the body sheet from a premature rupture of the container. Also, a sheet metal layer is often used as part of the label to add strength. The moisture resistance of the label sheets is especially important when the sheets are used together with mixed dough cans. Mixed dough cans are designed differently than other mixed containers so that they can be opened by hitting the container hard against a sharp surface, such as the edge of a kitchen counter, or by pressing the seam of the container with a utensil . The edges of the body sheet strip are typically supported and maintained together with a slightly adhered or non-adhered seam or seam. The label sheet is designed in this way to provide a substantial component of the total can resistance needed to prevent the can from opening prematurely. Also, when the label sheet or other outer cover is completely removed, the internal pressure of the mass and the impact force against the sharp edge or pressure from an implement causes the seam of the body sheet to separate, thus allowing that the dough product is removed from the can. In some "self-opening" cans, it is not necessary to provide external pressure after removing the label. In addition, dough containers are typically stored under refrigeration conditions. This type of storage is usually at a high humidity. During storage the label material is exposed to moisture which can weaken the cardboard sheet. This makes the strength of the label sheet even more critical since if the label sheet is exposed to moisture and has a lower moisture resistance, as is the case with most paper labels, the container may break prematurely In addition, the label is separated to open the container, as discussed above. However, the line along which the label is separated may occasionally deteriorate in a separation of the sheet or sheets of paper that may leave some material of the label on the outer surface of the body sheet. This problem, known as "partial detachment", can cause difficulties in opening the container.

As an alternative to conventional paper labels, many prior patents have mentioned the possible use of labels for dough cans or easy-open containers that are made of polymeric film. For example, the patent of E. U. A. No. 3,981, 433 to Thornhill et al. describes a mixed container for dough with a removable outer reinforcement layer or a cover layer. According to the '433 patent, the removable outer cover layer can be formed of paper, metal foil, or a suitable synthetic plastic material, such as polyethylene adhesively bonded to the outer surface of a fibrous body wall layer by means of of a polyvinyl alcohol adhesive applied separately. The patent of E.U.A. No. 4,235,341 to Martin et al., Discloses a dough container having inner and outer sheets on a sheet of fiberboard body. According to one embodiment, the inner sheet is a low density polyethylene film. The outer sheet is described as a thermoplastic paper film. The patent of E.U.A. No. 5,076,440 to Drummond, discloses a dough container having a label that can be made of plastic film. The patent of E.U.A. No. 5,084,284 for McDilda et al. discloses a dough container with a label that can be made of a plastic film. The patent of E.U.A. No. 5,326,023 to Rice et al. presents a dough container wherein the label layer is formed of a "biaxially oriented polymer film suitable". The film mentioned herein comprises a polypropylene film.

These films can theoretically provide improved moisture resistance for mass can labels. However, potentially useful film types for mass can labels are limited. The label must be easily removable in its entirety so that the consumer can open the container to obtain the inner dough product. Also, the type of film used should be easily separated from the body sheet and that the consumer can easily hold it to allow removal. Also, to properly open the dough cans, the label is preferably removed completely or at least completely separated along a predetermined line so that the spiral seam of the body sheet can be completely separated. Also, the film label can be of a kind that can be easily and completely removed from the container without partial detachments. Some films have predictable detachment characteristics; that is to say; they come off in a predictable direction, and thus can be useful for mass can labels because of the potential to completely remove the label and expose the seam of the body sheet. However, films that have predictable release characteristics can not provide the necessary strength to prevent the can from breaking. More specifically, films that have predictable release characteristics are typically susceptible to stretching over time, known as "deformation", as a result of pressure inside the can causing the seam expansion of the body sheet, which gradually weakens the resistance of the label and the total resistance of the container. Furthermore, not all polymeric films have proven to be capable of providing a removable bond to a cardboard container, as preferred in dough containers. Also, it is desirable to provide a decorative mixed container for expandable food products with a removable film label that has an improved resistance to moisture on the label sheet compared to paper labels and a reduced coefficient of friction, and that can Remove when detached from the container without partial detachments. The label should preferably have sufficient strength and dimensional stability to be used as a structural element of a dough container, and also be sufficiently removable to allow easy opening of the container.

BRIEF DESCRIPTION OF THE INVENTION This and other needs are provided, in accordance with the invention, by means of a decorative mixed container for consumer products with a tubular body sheet and a sheet of film label adhering to the body sheet. The film label sheet comprises a polymer film or laminar unit having permanently bonded inner and outer layers, wherein one of the layers is formed of a polymeric material having predictable release characteristics and the other layers have a high resistance to release in the circumferential direction. As an example, a film label sheet having an inner layer formed of oriented high density polyethylene and an outer layer formed of polyethylene terephthalate conveniently has both predictable release characteristics due to the oriented polyethylene and a high peel strength due to the polyethylene terephthalate. In this way, a very convenient removable label is provided for mixed containers which solves all the problems of the conventional labels mentioned above. In particular, a mixed tubular container is provided for advertising the products contained therein for consumers, wherein the tubular body sheet is formed of cardboard having inner and outer surfaces and opposite ends. The film label sheet is wrapped around the outer surface of the sheet of the tubular body and is detached from the sheet of the tubular body so that the body sheet can be separated and the container opened. As mentioned above, the film label sheet comprises a polymeric film or laminar unit having inner and outer layers. The inner layer adheres removably to the sheet of the tubular body and is formed of a polymeric material of a first type, preferably comprising a polyethylene film having predictable release characteristics. The outer layer of the film label sheet is permanently bonded to the inner layer and formed of a polymeric material of a second type, preferably comprising polyethylene terephthalate having sufficient strength to prevent deforming of the label sheet. Graphic indications are applied on at least a portion of the film label sheet so that they are visible to the consumer. These indications can be applied on the outer surface of the outer layer of the film label sheet or on the inner surface of a transparent outer layer so that it is visible to the consumer before the container is opened. In addition, indications such as coupons or games may also be applied to the interior surface of the inner layer of the label so that it is visible to the consumer who is buying after the label is removed. An adhesive such as dextrin is in contact with at least a portion of the inner layer of the film label sheet to adhere the label sheet to the outer surface of the tubular body sheet. The resistance to peeling of the label may be sufficient to prevent movement of the label so that the container will not open prematurely. The adhesive applied between the inner layer of the label sheet and the outer surface of the sheet of the tubular body can be a heat sealed coating, a cold sealed coating, or even a pressure sensitive adhesive. The film label sheet can be wound around the body sheet to create overlapping edges defining a seam extending between the opposite ends of the sheet of the tubular body. A hot melt adhesive can be applied between the overlapped edges to join the overlapped edges, or the adhesive used to adhere the film label sheet to the body sheet can also be used to adhere the overlapped edges. The film label sheet preferably has predictable release characteristics, so that a detachment in the film label sheet caused by a consumer will follow a path directed by the film label sheet. Alternatively, a plurality of perforations or laser markings may be used which extend around the outer surface of the sheet of the tubular body to direct a release on the film label sheet. The decorative tubular decorative container according to the invention is preferably used with dough cans and is thus designed to be opened through a side wall thereof. Also, the tubular body sheet defines a seam on which the opposite edges of cardboard rest and hold them with a seam or adhered slightly or not adhered. The film label adheres to the outer surface of the sheet of the tubular body so that the film label is detached from the sheet of the tubular body, the body sheet is separated to reveal the contents of the container. The invention provides a mixed multi-sheet decorative container having graphic indications applied to the inner layer and / or the outer layer of the film label. The graphic indications are thus protected from external forces by the outer layer of the film label and / or a lacquer layer, depending on which surfaces the graphic indications are applied. In addition, the moisture resistance of the film label sheet is not less than the film strength when it is not wet. In this way, the mixed multi-sheet container and the polymeric film label of the present invention provide a container that has the necessary strength to withstand storage in refrigerators and withstand the rigors of transportation, the consumer now being able to remove easily and completely.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES The present invention will now be described in more detail with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, this invention can be modalized in different ways and should not be considered as limiting the modalities set forth herein; Preferably, these embodiments are provided so that the description is comprehensive and complete, and fully transmits the scope of the invention to those skilled in the art. Similar numbers refer completely to similar elements. Figure 1 illustrates a tubular multi-sheet mixed container 10 for consumer products in accordance with the present invention. Although illustrated as having a circular cross-section, the tube can have any cross-sectional shape that can be formed by properly wrapping the tube around a mandrel. An example is a tube in a generally rectangular shape having rounded tips. The embodiment illustrated in Figure 1 and 2 is particularly useful for packaging dough products such as biscuits or rolls and includes a tubular body sheet 12, a coating sheet (not shown) adhered to the inner surface of the body sheet tubular 12, and a film label sheet 14 adhered to the outer surface of the tubular body sheet 12. The coating sheet may be omitted in certain applications such as packages for dry materials such as salt. The mixed container 10 also includes a closure of the plastic or metal end 16. The plastic or metal closure 18 can be secured to the opposite end of the mixed container 10. Other end closures can be used depending on the type of food product to be packaged. The tubular body sheet 12 of the mixed container 10 is preferably formed of cardboard, and the film label sheet 14, which adheres to the outer surface of the tubular body sheet 12, is preferably formed of a polymeric material. The film label sheet 14 comprises two layers permanently bonded together. With reference to Figures 3 and 4, the inner layer 40 comprises a polymeric material, preferably oriented high density polyethylene (HDEP) having predictable release characteristics. Other possible materials for the inner layer 40 include oriented polypropylene, oriented polyamide, and laminations thereof. The inner layer 40 preferably provides predictable release characteristics by allowing the material to detach predominantly in the specific direction dictated by the orientation of the polymer. The inner layer 40 is removably adhered to the body sheet 12 using an adhesive 42, such as a dextrin adhesive. Other adhesives are possible, such as heat-sealed coating that is activated by temperature, a cold-sealed coating, or a pressure-sensitive adhesive. The adhesive 42 may be applied to the entire inner surface of the inner layer 40 or it may be placed on only a portion thereof in either case preferably forming a peelable seal. The adhesive 42 can be applied separately to the body sheet 12 and / or the inner layer 40 of the film label sheet 14 during manufacture of the container such as with rollers and the like. For example, a cold-sealed coating can be applied to both the tubular body sheet 12 and the inner layer 40 of the paper label sheet 14 to promote better adhesion. In addition, a portion of the film label 14 defines a fastening point 15 for the consumer to begin to peel off the film label 14. The release seal preferably has a peel strength of approximately 1071-4,465 kg / m, and in particular around 3.57 kg / m. The peel strength must be performed at a level sufficient to prevent movement of the label 14 to prevent premature opening of the container 10, allowing easy removal of the label 14 by the consumer. The inner layer 40 can be made of a material such as a high density polyethylene as mentioned above. However, a high density polyethylene may stretch or deform over time in the circumferential direction when tension is applied, such as from the outward expansion of the body sheet caused by the expansion of the food product in the container. The deformation can damage the container if it is excessive, and can lead to premature opening of the container. In a useful manner, the film label of the present invention further comprises an outer layer 46. The outer layer 46 comprises a polymeric material which preferably has sufficient strength to prevent the body sheet 12 from breaking prematurely while providing a suitable surface for show graphs or instructions. The outer layer 46 preferably comprises polyethylene terephthalate number 45 (PET), although other thicknesses and films such as polyolefin materials can be used. Polyethylene terephthalate films can not typically be used individually as a film label 14 for dough containers due to their inferior holding characteristics and unpredictable peel characteristics. In this way, the inner layer 40 and the outer layer 46 are permanently bonded together to provide a film label sheet 14 with very high strength and predictable release characteristics. In addition, the outer layer 46 preferably has a kinetic coefficient of friction of at least as low as about 0.3 and can be coated with a lacquer 50 which can reduce the coefficient of friction even further below at least about 0.2. In one embodiment, the lacquer 50 is a catalytic lacquer, although other lacquers may be used, such as nitrocellulose lacquer. The outer layer 46 and the inner layer 40 are permanently bonded using an adhesive 44, such as a conventional adhesive used for polyethylene terephthalate and high density polyethylene materials. The outer layer 46 includes graphical indications 48 applied to at least one surface thereof. The graphic indicia 48 may include product information, coupons, games, package opening instructions, and / or rule enforcement information and are, in accordance with one embodiment, printed on the outer layer 46. With reference to figures 3 and 4, the indicia 48 can be printed on the outer surface of the outer layer 46, or they can be printed on the inner surface of the outer layer (if formed of a transparent material) using a method known as "reverse printing". The reverse printing of the graphic indications 48 on the inner surface of the outer layer 46 usefully protects the graphic indications of exposure to external elements, and therefore protects the indications that they appear blurred with spots or rips. The graphic indicia 48 can be rotogravure or flexographically printed on the outer layer 46. A lacquer layer 50 can be applied to the outer surface of the outer layer 46 to protect the film label 14 from outside elements. Figure 5 shows another embodiment of the present invention where the indications 48 are applied to the inner surface of the inner layer 40. In this embodiment, the indications 48 may be applied using reverse printing together with a transparent outer layer 46, or Indications can be rotogravure or flexographically printed together with a non-transparent outer layer. The film label sheet 14 is designed so that when the film label sheet 14 adheres to the outer surface of the sheet of the tubular body 12, the film label sheet 14 includes overlapping edges defining a seam that is extends between the opposite ends of the sheet of the tubular body 12. An adhesive is included between the overlapped edges to be joined. The adhesive may be the aforementioned adhesive 42 and / or a separate hot melt adhesive application. As described above, the inner layer 40 preferably has predictable release characteristics, so that the film label sheet 14 can be peeled off from the tubular body sheet 12 along a release path directed by the inner layer. The detachment path facilitates the removal of the film label sheet 14 from the tubular body sheet 12 so that the mixed container 10 can be easily opened. In one embodiment, the inner layer 40 comprises an oriented polymer. The polymer can be oriented around the tubular body sheet 12 so that the orientation of the polymer provides a predictable detachment path for the film label sheet 14 along the orientation direction. For example, the film label sheet 14 can be oriented so that the release path is in a circumferential direction around the mixed container 10. Alternatively, the film label sheet 14 can be wound around the tubular body sheet 12. in a helical direction so that the detachment path directed by the orientation of the polymer is along the helical direction. In a useful embodiment, the film label sheet 14 is wrapped around the tubular body sheet 12 so that the release path is circumferential direction, while the seam defined by the tubular body sheet and the overlapped edges of the Film label sheet are in a substantially similar helical direction. In this regard, the film label sheet 14 can be peeled off from the tubular body sheet 12 along the release path and along the seam defined by the overlapped edges of the film label sheet extending between the opposite ends of the tubular body sheet. Alternatively, Figures 6 and 7 show a line of perforations 62 and a laser mark 64 on the film label 14 that can also be used to direct a detachment along a desired detachment path. Many modifications and other embodiments of the invention will be apparent to those skilled in the art who are interested in the invention with the benefit of the teachings presented in the foregoing descriptions and the accompanying drawings. Therefore, it should be understood that the invention is not limited to the specific embodiments described herein and that it is intended to include modifications and other embodiments within the scope of the appended claims. For example, the tubular containers according to the present invention are not necessarily helically wound but instead can be wound longitudinally to create a "convolution" tube having an axially extending seam. In addition, although tubular containers according to the present invention have been described primarily in relation to food products, it is to be understood that the containers may be used in conjunction with other products. Although specific terms have been used herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
