Description

Semi-rigid tissue package

The present invention relates to a semi-rigid tissue package.

Rolled products, especially rolled tissue products such as paper towels, toilet tissues, disposable shop towels, and wipes, are sometimes packaged and shipped, for example, in bundles containing multiple rolls. Bundled packages often have two or more rolls stacked in a parallel manner with other two or more rolls. Often, to provide structural integrity to the bundle, rolled products are arranged in a vertical, stacked configuration (ie, the longitudinal axis of each core of each roll is generally vertical). Subsequently, the group of vertically oriented rolls is processed through a bundler applying an overwrap. The outer wrapper is sealed with a gusset seal on the leading and trailing sides of a group of rolled products. Placing rolls in this way allows stacking of packages and placement of stacks on pallets for shipping and display.

Conventional gusset seals offer many advantages for the bundled package of tissue products such as improved sealing and handling, but they often fold and crease multiple layers of the outer wrapper, which can result in poor visual appearance on the outer periphery of the bundle. need. In addition, folds and creases may block the visual aspects of the individually packaged packages contained therein. Folds and creases can also mask or distort valuable branding information on individually packaged packages. In addition, folds and creases can inhibit the full use of all package facets for advertising or branding.

Thus, a package comprising two or more rolled products is required, and the gusset seal does not significantly interfere with the visibility of individual rolled tissue products or branding marks on the individually packaged package enclosed therein. There is also a need for a package with gussets that do not interfere with the branding indication on one or more sides of the package.

Conventional outer packaged bundles have gussets and creases that can negatively affect the visual aesthetics of the package and limit the surface area of the package that can be printed, as well as gussets and seals are typically resealable. It cannot, and must be permanently ruptured to access and distribute rolled tissue products. In addition, the outer packaging is usually flexible and deformed after dispensing the product, resulting in a package that cannot be stacked and has poor aesthetics.

Accordingly, there is also a need for a package comprising two or more rolled products, where the package is resealable and maintains its shape and integrity after the product is dispensed.

The present invention solves many of the problems of bundles of prior art overpacked tissue products. The package is formed of a semi-rigid film that provides the package with a unique flat wall that is clearly visible when packaged and folded and printable with a brand designation. In addition, the semi-rigid film and package configuration provides a package that can be equipped with a resealable flap that provides easy and convenient repeated access to the package contents. In addition, after the product is dispensed, the package retains its shape and integrity, which is not only visually pleasing, but also allows the package to stack after the package is opened and the rolled product is dispensed.

Thus, in one embodiment the present invention provides a package for a tissue product comprising a bottom wall, a top wall, opposing side walls, and opposing end walls, wherein the package is closed to facilitate access into the package It includes a flap that is movable between a position and an open position, which can include portions of the side wall adjacent to the top wall of the package. The package is preferably made of a semi-rigid plastic material that allows the flap to bend when the flap is moved between the closed and open positions, but allows the package to retain its shape even after all products have been dispensed. It is preferred. In this way, the present invention provides a package that does not rely on separate containers such as frames, carriers, cartons, etc. to hold and protect the package contents and provide structural integrity to the package.

In certain embodiments, the package allows the user to open a larger portion of the product when the flap is in the open position, particularly if the package is full or nearly full, and a portion of the product is held by a portion of the package beyond the opening. It can be configured to allow access to the tissue product from the side as well as the top to allow gripping. In addition, by allowing access from both sides of the package, such as the top wall and adjacent sidewalls, the product can be removed without excessive distortion.

In other embodiments, the present invention provides a unified package formed from a single piece of semi-rigid plastic film having a bending stiffness of about 20.0 to about 60.0 mgf, more preferably about 25.0 to about 50.0 mgf. A single piece of semi-rigid plastic film is folded and sealed to form a package. The package contents are accessed and removed from the package by a flap integrally formed with the top wall of the package by forming a cut line in the single piece of semi-rigid plastic film used to form the package.

In still other embodiments the present invention provides a package for a tissue product comprising a bottom wall, a top wall with an opening disposed thereon, opposing side walls, and opposing end walls, wherein the package provides an opening. Includes flap covering. The flap can be formed of a completely separate material, can be separated from the package, or can include portions of the top wall to prevent the flap from being completely removed from the package. The flaps can be sealed releasably and resealably along one or more edges. The opening is provided in the package wall under the flap. The opening under the flap is preferably sized to allow the tissue product to be dispensed without deformation. The opening can be formed by cutting the film used to form the package, or it can be made by providing a perforation to the top wall under the flap and the flap can be attached to the top wall so that when the flap is opened, the top wall The parts are pulled with flaps. The perforation can extend around the entire periphery of the opening, or only around a portion of the opening, so that the parts of the top wall and sidewalls that are pulled when the flap is opened are not completely separated from the adjacent package material but connected to it. Is maintained as.

In other embodiments for opening the package, the flap may be provided with a label that peels from the package material on one side of the perforation line. As the label peels, the package material separates from the perforation to provide an opening. The perforations may extend along the top edge of one of the sidewalls where the sidewall meets the top wall, and then along the top wall, openings are formed along the two sides of the package.

The present invention generally provides a semi-rigid package for storing and dispensing tissue products, more particularly rolled tissue products such as, for example, paper towels, toilet tissues, disposable shop towels and wipes. Unlike prior art rolled tissue product packaging, which typically includes a thin, flexible film that is easily deformed and has little structural integrity after one or more products have been dispensed, the package is structured in the package even when dispensing the product. It is formed of a semi-rigid material that provides integrity. The package also provides a flap that allows easy access to the contents of the package and protects the product when the package is not in use.

The present invention is generally implemented in a package for a tissue product comprising a bottom wall, a top wall, opposing side walls and opposing end walls. The package is preferably a semi-rigid plastic material, more specifically greater than about 20.0, more preferably greater than about 25.0, even more preferably greater than about 30.0 mgf, such as about 20.0 to about 60.0 mgf, more preferably about 25.0 to It is formed from a web of plastic material with a bending stiffness of about 50.0 mgf. As used herein, “bending resistance” refers to the machine direction (MD) of a material through the Gurley resistance test as presented in the TAPPI standard test T 543 om-11 (Paper Bending Resistance (Gurley Type Tester)). It means the resistance measured by), and is reported in milligram (mg) force. A suitable test device is the Gurley Digital Resistance Tester Model 4171-D manufactured by Teledyne Gurley, based in Troy, New York, USA. Specimens were cut from the tissue dispenser and tested according to the TAPPI test referenced above. The length and width dimensions of the specimen to be cut and tested may be adjusted to accommodate the size or properties of the sample as described in section 6 of the procedure, but force measurements for any given sample size, depending on the test parameters used Including the use of conversion factors, it is normalized to correspond to 50.8 mm (2 inches) x 63.5 mm (2.5 inches), as presented in the TAPPI standard test 543 om-11. The table below shows the bending stiffness measured by MD for various materials including those useful in the present invention, and also provides specimen size, weight and mounting location for each material tested according to TAPPI standard test 543 om-11. .

The semi-rigid material allows the package to retain its shape even after all products have been dispensed. In this way, the present invention provides a package that does not rely on separate containers such as frames, carriers, cartons, etc. to hold and protect the package contents and provide structural integrity to the package. Rather than relying on a container to hold and hold the package contents, the package contents, such as a roll of tissue, directly contact the walls of the package to reduce packaging cost and complexity and to easily distribute the product.

The rigidity of the film material is important to ensure that the package retains its shape even after all contents have been dispensed, but the thickness of the semi-rigid film can be varied. In general, stiffness is a function of the elastic modulus of the film and its thickness. Thus, thinner films may be used as long as the elastic modulus of the film is high enough to provide stiffness in excess of at least about 20.0 mgf, about 20.0 to about 50.0 mgf, and more preferably about 25.0 to about 40.0 mgf. In certain preferred embodiments, the film is thick enough to provide the structural integrity and barrier properties necessary to protect and preserve the rolled tissue product contained therein, but sufficient to be easily folded and manipulated to form an instant package. It should be thin. Thus, in certain preferred embodiments, the film is at least about 50 μm, more preferably at least about 60 μm, even more preferably at least about 75 μm, such as about 50 to about 200 μm, even more preferably about 70 to about 100 μm Has a thickness of Calipers are measured according to the Tappi test method T 411 om-15 and typically have mil or μm units.

Like the thickness, the elastic modulus of the film is preferably stiff enough to resist collapse of the package when the content is dispensed, for example greater than about 20.0 mgf, more preferably greater than about 25.0 mgf, even more preferably about 30.0 It is high enough to give the film a flexural stiffness of greater than mgf, such as about 20.0 to about 60.0 mgf, more preferably about 25.0 to about 50.0 mgf. Films with the aforementioned stiffness are desirable for their ability not only to resist product disintegration after being dispensed from the package, but also to be flexible and easily bendable enough to fold into a package without additional processing steps such as scoring, cutting, and the like. Do.

After dispensing the product, in addition to being stiff enough to maintain the integrity of the package and flexible enough to allow bending and folding, the packaging film may have a greater than about 350 MPa, more preferably greater than about 450 MPa, such as about 350 to about 1250 MPa, More preferably, it may have an elastic modulus of about 450 MPa to about 750 MPa. In certain preferred embodiments, the film has a thickness of 70 to about 100 μm and an elastic modulus of about 450 to about 750 MPa. The secant modulus is the ratio of the stress to the corresponding strain at a strain of 1.0%, that is, the slope of a straight line connecting the origin and the point on the actual stress-strain curve at a strain of 1.0%. . The secant modulus is measured according to ASTM D790 and has megapascal units (MPa, pounds per square inch).

Films are made of one or more plastic resins, such as polyethylene (LDPE, LLPE, VLDPE, HDPE, MDPE), polypropylene, polyethylene terephthalate, nylon, other vinyl polymers and copolymers, such as vinyl acetate, vinyl alcohol, vinyl chloride, etc. Copolymers. In some embodiments, the film may include a combination of two or more of the synthetic resins described above. For example, a blend of two or more resins can be used to form a single layer film, or even a multilayer film. In particularly preferred embodiments, the film is a multi-layer film composed of two or more layers of the resin bonded together by any known technique such as laminating with or without coextrusion ("coex"), adhesives, coatings, and the like. to be. For example, the film may include co-extruded polyethylene / polypropylene laminated to polyethylene terephthalate (PET) or PET laminated to LDPE (low density polyethylene). In other embodiments, the film may include coextruded polyethylene (PE) and oriented polyethylene terephthalate (oPET).

The film can preferably be sealed to form one or more sealing edges when folded into a package. In certain embodiments, the film can be heat sealed. For example, the film may include a thermoplastic resin capable of bonding two parts of the film in an array facing each other by providing tack when heated. In other embodiments, portions of the films that face each other can be bonded using an adhesive bonding layer or coating. Preferred adhesive coatings are those based on thermoplastic resins, whereby the coating is non-tacky at room temperature, but becomes tacky and adhesive when heated, for example a coating of polyethylene resin or acrylic resin.

In certain embodiments, the package film may include a laminated film having one or more layers that react to heat and pressure by forming a seal of variable strength, wherein the strength of the seal is dependent on the amount of heat transfer and pressure applied. It depends in part. Thus, when the film folds into the film itself, such as a transverse end seal, the peelable seal area can be provided adjacent to the permanent seal area by varying the heat transfer, pressure and application width between the two areas.

Referring now to the drawings, the package 10 is a unitary piece folded to form a top wall 12, a bottom wall 14, a pair of side walls 16, and a pair of end walls 18. And a film 17. The package preferably contains a tissue product comprising a plurality of rolled tissue products, such as a roll of bathroom tissue 30 disposed inside the package. The film can be folded in any number of different configurations to form a four-sided package. For example, the package is around a rolled tissue product having a transverse end seal formed at the end of the package to define end longitudinal walls and marginal longitudinal opposite edges of the web joined together to form a longitudinal seal beneath the product. It can also be produced by continuously wrapping a web of film, and folding the film in a horizontal packaging motion.

In other embodiments, such as those shown in FIGS. 1-3, the single unitary piece of film 17 is folded and sealed to provide a pair of opposing transverse edge seals 13, 15 and the bottom wall 14 It is possible to form a package 10 having a longitudinal seal (not shown in FIG. 1) disposed thereon. Depending on the nature of the film, the seal can be a heat seal or a cold seal, and can be a permanent seal or a resealable seal. In a particularly preferred embodiment, all edges, transverse edge seals and longitudinal bottom seals are permanently heat sealed. Although the embodiment shown in FIGS. 1 to 3 includes a pair of opposing transverse edge seals and a longitudinal seal disposed along the bottom wall, the film is oriented and packaged around the package contents, facing the seal. The edges are oriented in the longitudinal direction of the package and the bottom seal is oriented in the transverse direction of the package.

With continued reference to FIGS. 1 to 3, the top wall 12 includes flaps 21 that can be separated from the top wall 12 to provide access to the rolled tissue product 30 in the package. The flap 21 is defined by a perforation line 19 disposed on the top wall 12. The perforations can be made using methods including, but not limited to, scoring, drilling, chemical treatment, preferably laser scoring, laser drilling, mechanical scoring, mechanical drilling, embossing methods, or combinations thereof. As shown in FIG. 1, the perforation line 19 forming the flap 21 extends along only a portion of its periphery, such as three sides, with the fourth side attached to the top wall 12 Put it. The attached fourth side can form a living hinge that allows the flap 21 to be moved between a closed position and an open position. When the user breaks the film 17 along the perforation line 19 to separate the flap 21 from the top wall 12, the opening in the top wall of the package allows the user to access and distribute the tissue product 30 Is formed.

In other embodiments, the flap may be formed entirely of separate pieces of material and separated from the package. The flaps can be sealed releasably and resealably along one or more edges. The opening is provided in the package wall under the flap. The opening under the flap is preferably sized to allow the tissue product to be dispensed without deformation. The opening can be formed by cutting the film used to form the package, or it can be made by providing a perforation to the top wall under the flap and the flap can be attached to the top wall so that when the flap is opened, the top wall The parts are pulled with flaps. The perforation line may extend around the entire periphery of the opening, or only a portion of the opening, such that only a portion of the top wall is pulled when the flap is opened. In this way, the flap is not completely separated from the adjacent top wall, but remains connected to it.

During the manufacture of the package, the web is preferably pre-cut with die-cut perforations or otherwise provided with perforations corresponding to the desired shape of the opening. In other embodiments, the flap can be applied to the web as a separate piece after a perforation line defining the opening is disposed on the web. When the flap is applied as a separate piece, it is preferably a label with an adhesive covering one side thereof. The label is applied to the web to cover die-cutting perforations or other perforations. As the web advances, the label folds into the underlying substrate and remains in place.

As shown in FIG. 3, when the flap 21 is pulled back from the top wall 12, it forms a dispensing opening through which rolled tissue products 30 can be dispensed. A portion of the flap 21 remains attached to the top wall 12 along one of its edges. Preferably, the size of the opening 19 and thus the size of the flap 21 is at least about 30% of the surface area of the film 17, advantageously at least about 50% of the surface area of the film 17 so that the container 10 ) Is more easily accessible to the rolled tissue product included in the.

Alternatively, the flap may have a perforation line completely disposed around its periphery on all sides so that it can be completely separated from the film when removed by the user to form a distribution opening. However, it is believed that it may be more desirable to extend the perforation line around only a portion of the perimeter of the opening, so that the package material within the perforation line remains connected to the adjacent package material along one edge of the flap. This can eliminate the need to form a permanent seal at this location, in that the strength of the package material that remains intact will prevent the flap from being completely removed from the underlying package material. According to this feature, the perforation line 19 shown in FIGS. 1 to 3 is not a closed curve extending around the entire periphery of the opening.

In certain embodiments, such as those shown in Figures 1-3, the sealing label 20 can be attached to the flap 21 when the package 10 is not in use to seal the flap in a closed position. Advantageously, the sealing label 20 is permanently attached to the flap 21 using a suitable first adhesive and resealable to the top wall 12 using a second adhesive. As shown in FIG. 1, the sealing label 20 generally covers a portion of the top wall 12, which defines the sealing area 27. The sealing area 27 ends before any side 16, 18 of the package 10. Thus, in the embodiment shown in FIGS. 1-3, the sealing area 27 does not extend to any side of the package and the package opening is completely disposed on the top wall 12 of the package 10.

The opening of the package can be facilitated by providing a sealing label 20 on the tab 22. The tab 22 extends from a portion of the sealing label 20 and is preferably not attached to the top wall 12, but rather freely hung from the package for easy gripping by the user. In this way, tab 22 can be gripped and pulled by the user's finger and thumb to initiate removal of label 20 and then flap 21. In addition, the tab 22 can facilitate closing of the container, providing an adhesive-free surface for the user to hold and position the label 20 for proper sealing and fixing of the flap 21. The tap size and its shape can be optimized for functionality. For example, in certain embodiments, the tab is semi-circular and has a surface area of about 1 to about 10%, more preferably about 2 to about 5% of the total surface area of the sealing label.

The sealing label 20 can be removably attached to the top wall 12 by applying an adhesive to its underside. Subsequently, the sealing label 20 may contact the top portion 12 to seal the package 10. Advantageously, the adhesive provides a removable seal between seal label 20 and top 12. In such embodiments where the tab is provided on the sealing label, the adhesive is preferably not applied to the tab. Alternatively, when an adhesive is applied to the tab, a blunting agent, chemical or material layer is applied to the top wall to prevent the tab portion from adhering to the top of the package.

4 and 5 are the second of the present invention comprising a package 10 having a top wall 12, a bottom wall (not shown), a pair of side walls 16 and a pair of end walls 18. An example is shown. The package includes a plurality of rolled tissue products 30. The end walls are the top, bottom and side walls joined together in the transverse end seal 27 on each end wall 18, with the extension 29 of the side walls 16 folded inward at the end of the package 10. Includes extensions of. The pair of side walls 16 are separated from the bottom and top walls of the pair of longitudinal edge seals 23 and 25. In this way, the rear side wall and top wall are substantially planar and are very suitable for accommodating product markings. In addition, the edge seals 23, 25 can further improve the stiffness of the package 10 to make it easier to maintain its shape once its contents are dispensed.

In order to allow the package to be resealed and also to facilitate access to the tissue product 30 in the package 10, a single opening is formed in one of the adjacent wall and end walls 18 of the top wall 12. . The opening can be covered by a flap 21 having a sealing label 20 extending around a portion of its periphery. The tab 22 is left unsealed to facilitate the initiation of package opening. The width of the flap 21 is approximately equal to the width of the opening OW (shown in FIG. 3). In particularly preferred embodiments, such as shown in Figure 3, the shape of the flaps 21 and openings are substantially similar, preferably the openings are from about 90 to about 110% of the width of the rolled tissue product RW, more preferably It has an opening width (OW) of about 95 to about 105%.

In certain embodiments, it may be desirable for the openings and flaps to have similar shapes and dimensions, but the invention is not so limited. In other embodiments, an opening is provided in the package walls below the flap in which the opening has a width less than the width of the flap. In these embodiments, the opening under the flap is preferably sized to allow the tissue product to be dispensed without deformation, and the flap is sized to form a seal between the flap and the top wall along a portion of the perimeter of the opening. The opening can be formed by cutting the film used to form the package, or it can be made by providing a perforation to the top wall under the flap and the flap can be attached to the top wall so that when the flap is opened, the top wall The parts are pulled with flaps. The perforation can extend around the entire periphery of the opening, or only around a portion of the opening, so that the parts of the top wall and sidewalls that are pulled when the flap is opened are not completely separated from the adjacent package material but connected to it. Is maintained as.

Referring now to Figures 6 and 7, yet another embodiment of a package according to the invention is shown. The package includes a top wall 12, a bottom wall 14, a pair of side walls 16 and a pair of end walls 18. The pair of end walls 18 includes a folded and sealed closure, which will be described in more detail below. The top wall 12, the bottom wall 14, the side walls 16 and the end walls 18 are all integral parts of a single sheet of semi-rigid film material 17.

The side walls 16 include permanent longitudinal side joints 40, 42, 44, 46. One of the longitudinal side seams 44 is formed by sealingly engaging the marginal edges 41 and 43 of the sheet material 17 with each other. Other longitudinal side joints 40, 42 and 46 are formed by folding and sealing the sheet material 17 in a face-to-face arrangement with itself. The longitudinal side seams 40, 42, 44, 46 are preferably permanently secured to each other through any conventional sealing technique known in the art, such as heat sealing or welding. The end walls 18 of the package are also preferably sealed to close the package. In certain embodiments, the end walls are also hermetically closed, for example along the permanent transverse end seal 29.

The package of the embodiment shown in FIGS. 6 and 7 can be made by folding a single sheet of semi-rigid material, such as the sheet shown in FIG. 8. The sheet may have a rectangular shape with parallel edges 41 and 43 that are joined together and sealed to form a permanent edge seal (shown as longitudinal seal 44 in FIGS. 6 and 7), and are tubular in shape. A structure (not shown) is formed. However, the width of the permanent edge seal can be varied, but in some embodiments the width can be from about 2 to about 10 mm. The tube is then converted into a parallelepiped package with permanent sealing lines 40, 42, 44, 46 forming four permanent square edges of the package 10 by forming additional permanent seals. The opposing side walls 16 of the parallelepiped are folded in at the bottom edge, and the first end seal is formed to seal the first end wall of the package.

Before forming the second transverse end seal, the package is in the shape of a rectangular box with an open end through which rolled tissue products may be inserted to fill the package. After filling with the tissue product, the opposing side walls are folded over at the top edge so that the package is sealed parallel to the top edge of the top of the package to form a second end and seal the second end wall of the package.
