Description

SHELF-READY PACKAGE AND METHOD FOR MANUFACTURING THE SAME

The object of the invention is a shelf-ready packaging for products described in the preamble of claim 1 and a method for forming shelf-ready packaging for products described in the preamble of claim 11.

The shelf-ready packaging according to the invention re^¬ lates advantageously to made-to-order manufacture of easy-to- use shelf-ready cardboard or paperboard packaging to be used for the packaging and display of different products in stores .

In a solution according to prior art, shelf-ready packaging is made by folding carton blank plates to create a package around the products, said package having perforated sides that can be torn open to get the products out of the package. This packaging technique is called the "wraparound" tech^¬ nique. The problem in these solutions is the perforation's unreliability and lack of precision. When ripping the package open, the package may tear at the wrong line - in which case the products are not displayed as planned, they fall out of the package, or they are hard to pick from the package. The torn part may also be sharp and may sometimes injure the hand of the person handling it or the hands of store customers. Opened packages may also be unsightly if the perforation tears in the wrong place. In addition, the opening of perfo^¬ rated shelf-ready packaging requires physical hand-strength and takes a lot of time. In the existing tear strip implemen- tations, the tear strip is located on the inside of the closed shelf-ready package, and when opening the shelf-ready package, the tear strip cuts the paperboard wall of the shelf-ready package at the tear strip location ripping the wall of the shelf-ready package into two, leaving an unat^¬ tractive tear surface.

In another solution according to prior art, products are placed on top of a base , which is folded from its edges, and then the actual carrying carton is placed upside down on top of the products. This packaging technigue is generally known as the "tray" technique. This technique requires a lot of packaging material: most parts of the product are covered by two layers of packaging material, and there are even more layers at the edges as they are reinforced by folding. Be^¬ cause the carton has a lot of folded edges, opening empty packages to form compact plates for recycling is a lot of work .

The aim of the present invention is to eliminate the drawbacks mentioned above and to create shelf-ready packaging that can be opened quickly, easily and safely. Another aim is to create shelf-ready packaging that is suitable as such for recycling and that can be easily and quickly turned into essentially straight plates to take up little space and to make it easy to deliver the packaging to recycling. Yet another aim is to create shelf-ready packaging that provides an easy way to arrange an information platform for the contained product. In addition, the aim of the invention is to create an easy and cost-effective method for forming shelf-ready packaging for products. Shelf-ready packaging for products according to the invention is characterized by what is disclosed in the char^¬ acterization part of claim 1. Correspondingly, the method according to the invention is characterized by what is dis^¬ closed in the characterization part of claim 11. Other embod^¬ iments of the invention are characterized by what is disclosed in the other claims . In a solution according to the invention, the base of the shelf-ready packaging is advantageously made with carton forming equipment configured to produce dimensions appropri- ate for each batch of products. A detachable side or sides of the detachable part of the packaging, for example a lid, one end and the sides, are set into place and attached to the package base with a fastener, such as adhesive paper or tape. A tearing element, such as a tear strip, is placed between the outer surface of the shelf-ready packaging and the fas^¬ tener, which attaches the detachable part and the package base to each other. When the shelf-ready packaging is opened, the tearing element rips open the seam made by the fastener between the package base and the detachable sides allowing the shelf-ready packaging to be opened easily and safely at exactly the right location. The tearing element rips the fastener lengthwise, leaving the shelf-ready packaging walls completely intact. The lengthwise tearing element placed between the outer surface of the shelf-ready packaging and the fastener can be integrated for example into the fastener^¬ 's adhesive side or, alternatively, attached to the outer surface of the shelf-ready packaging with adhesive, either on the edge of the wall of the detachable part or on the edge of the wall of the package base.

The advantages of the solution according to the invention include the ability to detach the sides of a shelf-ready pack^¬ aging easily, gently and quickly with tear strips. Compared to current shelf-ready packagings, the time required to open the package is cut in half. The tear strips allow the package to be opened reliably from the right place by tearing the fasten^¬ er in two, thus avoiding any accidental ripping of the package base. A shelf-ready packaging can be opened with precision for example from the junction of the base and the side walls and from the junction of the back end and the side walls. In addition, the edge left after opening is clean and safe be^¬ cause no sharp edges are left behind. When only the base and back wall of the shelf-ready packaging remain, the products in the packaging are easily accessible by customers. Anti- slippage structures can be added to the base of a shelf-ready packaging to prevent products from falling over when the pack^¬ aging is opened. An example of a simple anti-slippage struc- ture is a corrugated surface made of corrugated cardboard.

Another advantage is that an almost minimum amount of material is used when manufacturing the packaging because there are very few overlapping package surfaces, which keeps the packag- ing material costs low. Shelf-ready packaging according to the invention is folded so that the best possible bearing capacity with the minimum amount of material is achieved. Another ad^¬ vantage is that it is light, easy and quick to open up used packaging into a single plate for recycling.

An advantage of another advantageous embodiment is that the package front end (or part thereof) can be folded downwards to display its inner surface, which can contain product infor^¬ mation in the form of printed text and/or images, for example. An advantage of yet an another embodiment is that the package front end (or part thereof) can be folded downwards, revealing anti-slippage structures such as corrugated cardboard on its inner surface. This supplementary anti-slippage package base can be used to display products from a previous batch in front of newer same kind of products. The following section describes the invention in greater de^¬ tail using embodiment examples with reference to the attached simplified drawings, in which figure 1 presents one of the basic principles of a shelf- ready packaging used in the solution according to the invention, viewed obliquely from the side and above,

In figure 1, one of the basic principles of the shelf-ready packaging used in the solution according to the invention, is presented obliquely from the side and above. The shelf-ready packaging 1 consists at least of a package base 2, a detacha^¬ ble part 3, a fastener 4 and tearing elements 5. Tearing ele^¬ ment 5 can be a strip-like or thread-like element. For exam- pie, it can be a thin tear strip, thread, string or some other suitable thin and/or narrow element with good tear resistance, with which the fastener 4 can be torn from the corners of the shelf-ready packaging 1. In this example solution, tearing element 5 is a tear strip. In this solution, the package base 2 comprises a base 2a and a back end 2b of the shelf-ready packaging 1. Corresponding^¬ ly, the detachable part 3 comprises a continuous top part i.e. a lid 3a, a front part i.e. a front end 3b and right and left sides 3c of the shelf-ready packaging 1. The package base 2 and the detachable part 3 are attached to each other with fasteners 4, such as tapes or adhesive papers. The fas^¬ tener 4 can also be a paper strip, to which a tear strip 5 is attached. The paper strip with tear strip 5 is glued (e.g., with hot gluing) to the package base 2 and the detachable part 3 when the shelf-ready packaging 1 is closed. In the example mentioned above, the glue can be attached to either the paper strip or the packaging. Tear strip 5 is attached lengthwise to the glue surface of fastener 4, for example, essentially to the center line of the fastener. Tear strips 5 could also be attached to the lower parts of the side walls 3c and to the back parts of the side walls 3c of the detacha^¬ ble part 3, as long as the placement is close enough to the outer edge to catch the tear strips under fasteners 4 as the shelf-ready packaging 1 is being closed. The tabs of the tear strips 5 have opening cuts 5a to make it easier to open the tear strips.

In figure 2, the shelf-ready packaging 1 according to figure 1 is presented obliquely from the side and above while being opened. The shelf-ready packaging 1 is filled with a set of product packages 6. The shelf-ready packaging 1 according to the invention can be easily opened by pulling from the four tear strips 5 mentioned above, in which case the fasteners 4, such as tapes or adhesive papers, that attached the package base 2 and the detachable part 3 to each other tear length^¬ wise with the tear strips 5, separating the package base 2 and the detachable part 3 from each other. The tear strips 5 are manufactured from tough material to avoid breakage and to ensure they cut the fasteners 4 set on top of them. The pack^¬ age base 2 consists of the base 2a, the back end 2b and sup^¬ portive parts 2c, which keep the back end 2b firmly in an upright position. In addition, an anti-slippage element 2d can be included into the package base, which anti-slippage element can be, for example, corrugated cardboard. The de^¬ tachable part 3 and the package base 2 can be separated from each other with precision between the side walls 3c and the base 2a, between the side walls 3c and the back end 2b, and between the front end 3b and the base 2a. In the example according to figure 2, the front end 3b of the detachable part 3 has not been attached to the package base 2 with the fastener 4, which expedites the opening of the shelf-ready packaging 1.

In figure 3, the shelf-ready packaging 1 and the detachable part according to figure 1 are presented completely opened, viewed obliquely from the side and above. The detachable part 3 of the shelf-ready packaging 1 is completely detached from the package base 2 using the tear strips 5. Product packages 6 are on display, making it easy for shop customers, for example, to pick them out of the shelf-ready packaging 1 placed on a shop shelf. Using the tear strips 5 to open the shelf-ready packaging 1, it opens from just the right, planned location, leaving the products 6 on a neat package base 2 with no visible tears. The anti-slippage element 2d prevents the product packages 6 from sliding and falling over in the opened shelf-ready packaging 1. The supports 2c in- eluded in the package base 2 make the package base 2 sturdy and keep the back end 2b upright. The detachable part 3 does not have side folds and it is easy and quick to deliver it to recycling as a straight plate. Figures 4a, 4b and 4c present one possible package base 2 of the shelf-ready packaging 1 as an opened package blank and as assembled into the folded position according to the folding pattern of the package blank. In figure 4a, upper part ol of the package blank forms the back end 2b of the package base 2 and part o2 at the bottom of the figure forms the base 2a of the package base. In figures 4b and 4c, the folding pattern demonstrates how the package base 2 is formed from the straight package blank. The upper part ol of the package blank has been raised and fixed in an upright position with support tape o3, forming the continuous back part i.e. the back end 2b of the package base 2. The lower part o2 of the package blank has been folded to be advantageously perpendicular to part ol, forming the base 2a of the package base. After use, the pack^¬ age base 2 can be easily and quickly opened to form a recycla^¬ ble plate by tearing the part o2 of the back-part open with a simple pulling gesture, for example. Figures 5a and 5b present a second embodiment example of the shelf-ready packaging 1 according to the invention. The pack^¬ age base 2 comprises a base 2a, a back end 2b and a front end 2e of the shelf-ready packaging 1. Correspondingly, the de^¬ tachable part 3 comprises a continuous top part i.e. a lid 3a and side walls 3c of the shelf-ready packaging 1, which de^¬ tachable part is attached to the base 2a, back end 2b and front end 2e of the package base 2 with fastener 4 or a simi^¬ lar fastener that comprises a tear strip 5. The front end 2e of the package base 2 has been arranged to be folded down to display not only product packages 6 but also product infor^¬ mation 7, such as product description, placed on the inside of the front end 2e, which information would be visible below the actual products 6. Product information 7 can be attached to the front end 2e, among other ways, by printing it directly on the packaging material or by attaching it with an adhesive sticker on the packaging material. The seam between the base 2a and the front end 2e can also have a tearing crease, in which case the front end 2e including the product information 7 can be easily removed when needed.

Figures 5c and 5d present a third embodiment example of the shelf-ready packaging 1 according to the invention. This exam- pie is like the second example presented above, with the dif^¬ ference that the front end of the shelf-ready packaging 1 has two parts: upper part 3b' of the front end, which is attached to the lid 3a of the detachable part 3, and lower part 2e of the front end, which is attached to the base 2a of the package base 2. The shelf-ready packaging 1 according to this example comprises product information 7, which can be folded down as in the previous example, but in this case the lower part 2e of the front end is not the full height of the shelf-ready pack^¬ aging 1 as in the solution according to figure 5. Instead, the height of the lower part 2e of the front end can be optimized to be smaller when needed.

Figures 6a and 6b present a fourth embodiment example of the shelf-ready packaging 1 according to the invention. This exam- pie is like the second example presented above, but is differ^¬ ent in that the front end 2e is folded out to become a hori^¬ zontal extension of the base 2a. The upper surface of the folded front end 2e has an anti-slippage structure, the same as the upper surface of the base 2a. When there are product packages 6' from the previous shelf-ready packaging left over on the product shelf, these can be easily placed in front of product packages 6 of a new shelf-ready packaging 1 on top of the front end 2e, provided with the anti-slippage structure, when it is folded down into its horizontal position.

Figures 7a and 7b present sectioned and simplified front views of two attachment principles for the detachable part 3 and the package base 2 of the shelf-ready packaging 1 according to the invention. The proportions of the figures are not necessarily correct and at least the thicknesses of the fastener 4 and the tear strip 5 have been exaggerated for clarity. The thickness of the tear strip 5 can normally be around 0.1 millimeters, for example. A product package 6 is packed inside the shelf- ready packaging 1 and it is bounded by the side wall 3c of the detachable part 3 from the side and the base 2a of the package base 2 from below. The package base 2 and the detachable part 3 are attached to each other with the fastener 4, which can be tape or adhesive paper, for example.

In the solution according to the invention, it is essential that the package base 2 and the detachable part 3 are separate from each other before they are attached to each other. The tear strip 5 is placed on the outer surface of the shelf-ready packaging 1 between the fastener 4 and the shelf-ready pack^¬ aging 1, on the wall of either the package base 2 or the de^¬ tachable part 3 and essentially close to the edge of the wall. The tear strip allows you to tear up the fastener 4, in which case the package base 2 and the detachable part 3 separate from each other reliably without risking that they rip apart uncontrollably. In the existing tear strip implementations, the tear strip is located on the inside of the closed shelf- ready package, and when opening the shelf-ready package, the tear strip cuts the paperboard wall of the shelf-ready package at the tear strip location ripping the wall of the shelf-ready package into two, leaving an unsightly tear surface. In the implementation of figure 7a, the tear strip 5 is inte^¬ grated lengthwise on the inner surface i.e. on the adhesive surface of the fastener 4. The tear strip 5 is located on the lower edge of the side wall 3c of the detachable part 3. When pulling the tear strip 5, it cleanly splits the fastener 4 lengthwise, reliably separating the package base 2 and the detachable part 3 from each other. In the implementation of figure 7b, the tear strip is attached to the lower surface of the base 2a of the package base 2, essentially close to the side edge of the base 2a. The side wall 3c of the detachable part 3 and the base 2a of the pack^¬ age base 2 are attached to each other with the fastener 4 so that the tear strip remains between the lower surface of the base 2c and the fastener 4. When pulling the tear strip 5, it cleanly splits the fastener 4 lengthwise, reliably separating the package base 2 and the detachable part 3 from each other. Figure 8 presents a roll of fastener 4, used for the shelf- ready packaging 1 according to the invention, viewed obliquely from the side and above. There is an adhesive surface 8 on one side of the fastener 4, which can be an elongated tape or adhesive paper released from the roll, which adhesive surface attaches to the components to be attached to each other, such as the package base 2 and the detachable part 3 of the shelf- ready packaging 1, and attaches the components to each other. The lower surface of the fastener 4, which is the adhesive surface, has an integrated tear strip 5. Because the tear strip 5 is integrated into the fastener 4, it advantageously goes automatically in exactly the right place when the shelf- ready packaging 1 is being closed. The material used in the tear strip 5 is tough and durable so that it does not break when opening the shelf-ready packaging 1 and so that it can gently cut open the fastener 4 material.

Figures 9a, 9b and 9c present another possible detachable part 3 of the shelf-ready packaging 1 as an opened package blank, as a folding pattern for the package blank and as a fully folded structure. In figure 9a, upper part al and a3 of the package blank form the front end 3b of the detachable part 3 and part a5 in the middle in the lower part of the drawing forms the lid 3a of the detachable part 3. Correspondingly, parts a4 and a6 form both sides i.e. the side walls 3c of the detachable part 3. In figure 9b, the folding pattern demon^¬ strates how the detachable part 3 is formed from the straight package blank. Front parts al and a3 of the sides of the de- tachable part 3 are folded against each other to form the continuous front part i.e. the front end 3b of the detachable part 3. Parts al and a3 are attached to each other with a fastener 4 comprising a tear strip 5 and an opening cut 5a. The fastener 4 can also extend slightly over the lid 3a of the detachable part 3. After use, the detachable part 3 can be easily and quickly opened to form a recyclable plate by de^¬ taching parts al and a3 of the front end 3b from each other with the tear strip 5. To a person skilled in the art, it is obvious that the inven^¬ tion is not limited to the embodiment examples above, but that it can be varied within the scope of the claims presented below. Accordingly, method phases, for example, may occur in a different order than presented above, method phases may be omitted or other method phases not presented may be included. In addition, some method phases could include more or less steps than presented above. To a person skilled in the art, it is also clear that shelf- ready packagings according to the invention can be different than those presented above. The simplest and most common shelf-ready packaging is rectangular in form. This is used as an example in all the figures. However, shelf-ready packagings can take other forms besides the typical rectangular box-like shape. Thus, the form could be, for example, polygonal, circu^¬ lar, or oval, depending e.g. on the form of the product pack^¬ ages placed inside the shelf-ready packaging. A shelf-ready packaging can also include more than one row of product pack^¬ ages .

To a person skilled in the art, it is yet clear that the de^¬ tachable part of a shelf-ready packaging can be removed in some other manner than with two or more tear strips. For exam^¬ ple, the detachable part can be removed with one tear strip circling completely around the detachable part.

In addition, to a person skilled in the art, it is clear that the tear strip can be unattached to the fastener, such as adhesive paper or tape, and merely be placed under it . In addition, it could be attached either to the side edges of the detachable part, as mentioned previously, or on the underside edge of the package base and/or the outer edge of the back end .

It is also clear to a person skilled in the art that shelf- ready packagings made with the method can be some other mate^¬ rial than recyclable fiber material. In this case, a shelf- ready packaging can be manufactured from some other foldable material than corrugated cardboard. For example, shelf-ready packaging can be manufactured from different types of card^¬ board, paperboard, or paper, or even woven materials, plastic, metal, or a combination of materials. The package base and the detachable part of the box can be made from the same material or from different materials.
