Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to individual handles for boxes and methods for making same. [Background technology]

[0002] Handles are used in several applications, such as on paper or cardboard boxes used in retail, and are typically grippable strips that are glued to the box and allow a user to grasp and lift the box.

[0003] Generally, a handle for a box is required to have mechanical durability in terms of load-bearing capacity, flexibility, and the like.

[0004] Current handles on the market are known to have undesirable characteristics such as low comfort and weight bearing capacity that are undesirable for the user.

[0005] Despite recent advances, handles are still in need of improvement. Summary of the Invention

[0006] It is an object of the present disclosure to at least partially overcome the problems of the existing art and to provide a handle that is more useful in box applications, with a comfortable and load-bearing capacity. This and other objects that will become apparent hereinafter are achieved by a handle for a box according to a first aspect of the invention, the handle comprising: The lower liner and an upper liner secured to the lower liner and having a central cutout; Strip and Equipped with the strip comprises a first end, a second end, and an elongated central portion extending between the first end and the second end; the first end and the second end are adjacent opposite ends of the central cutout and are secured between the upper liner and the lower liner; the elongated central portion has a length greater than a length of the cutout portion and is positioned to form an arch when pulled in a direction away from the lower liner; The strip comprises at least a layer A, a layer B, and a layer C; Layer B is disposed between layers A and C; Layer A comprises a nonwoven fabric, Layer B comprises an adhesive; Layer C includes a reinforcing material; Layer A constitutes the outer surface of the strip.

[0007] The handles of the present invention have proven very promising for attachment to boxes, such as those used in retail stores. The present disclosure is based on the fact that a handle comprising a strip having a nonwoven layer, an adhesive layer, and a reinforcing layer exhibits surprisingly high mechanical properties and provides a strip that feels comfortable to the user when gripped. Furthermore, the present disclosure is based on the fact that the layer structure of the present disclosure, combined with the nonwoven layer that forms the outer surface of the strip, provides a handle that exhibits surprisingly high mechanical properties while also exhibiting surprisingly high comfort for the user. In addition to providing user comfort, the outer surface of the strip, which comprises a nonwoven layer, provides a handle with good fixation, further improving the fixation of the strip to the lower and upper liners. Thus, the present disclosure provides a handle with improved mechanical properties and high comfort for the end user.

[0008] It is understood that when the elongated central portion is engaged (pulled away from the lower liner), the elongated central portion forms an arch-like shape, a semicircular shape, or substantially any shape that at least partially encloses the void, and the void is enclosed by the elongated central portion, the upper liner, and / or the lower liner.

[0009] It will be appreciated that the extension center portion may be compressed or folded onto the upper and lower liners, for example, during storage of a stack of handles or a stack of boxes with attached handles, etc. This allows, for example, stacks of handles and / or stacks of boxes with attached handles to be efficiently stored in a room.

[0010] In some embodiments, layers B and C are arranged as a core, and layer A is arranged as a case that substantially covers the core. Arranging layers B and C as a core provides a strip with good mechanical properties. Arranging layer A as a case that substantially covers the core provides a strip with improved mechanical properties and ergonomics, such as providing a soft outer surface and reducing the degree to which the strip presses against the user's hand during use, thereby improving comfort in the user's hand. Preferably, layer A completely covers the core of the strip, providing a comfortable surface for the entire handle strip. It is understood that the two lateral edges of the strip that form surfaces substantially perpendicular to the longitudinal direction of the strip do not necessarily cover layer A. Layer A may, for example, be arranged as a case that covers at least 80%, at least 90%, or at least 95% of the core.

[0011] In some embodiments, the strip is folded to position layer A as substantially the entire outer surface of the strip. The strip is folded at least once, such as at least twice. The strip may be folded at one-third of the width of the strip, one-third and two-thirds of the width of the strip, one-quarter of the width of the strip, one-quarter and two-quarters of the width of the strip, and / or one-quarter, two-quarters, or three-quarters of the width of the strip. The strip may be folded to overlap at the middle of the strip. The strip may be folded twice to create two longitudinal folds: a first side, a second side, and a center. The first side and second side may be folded to overlap, for example, at substantially the center of the folded strip, such as the center of the center. Thus, a strip with improved comfort is provided, since layer A is positioned as substantially the entire outer surface of the strip and at the two lateral edges of the folded strip. It is understood that the three portions may have substantially the same width or different widths. After being folded, the first side portion, the second side portion, and the center portion may be secured to one another using an adhesive, such as a polyethylene adhesive or a hot melt adhesive.

[0012] The strip may be folded at its center, i.e., at a position substantially equidistant from the two opposing lateral ends of the strip. A folded strip as described above has layer A positioned as almost the entire outer surface of the strip, thereby improving the comfort of the strip, since the user's hand primarily interacts with layer A. Expressed differently, a strip comprising layers A, B, and C may be folded to provide a strip macrostructure in which the layers are arranged as follows: ABCCBA. It is understood that as a result of the folding, the folds form an outer covering at the first lateral end of the strip that is opposite the second lateral end in the longitudinal direction. Layer C may be secured to itself after folding using an adhesive, such as a polyethylene adhesive or a hot-melt adhesive.

[0013] In some embodiments, the adhesive has a viscosity of 10 to 50 g / m 2 Contains polyethylene adhesive with a weight of 10-50g / m 2 Polyethylene adhesives with a weight of 10-50g / m provide good adhesion between the layers of the strip. 2 A polyethylene adhesive having a weight of 1000 .mu.m provides a suitable strong bond between the layers of the strip.

[0014] In some embodiments, the nonwoven fabric has a density of 20 to 100 g / m 2 Weight: 20~100g / m 2 The nonwoven fabric having a weight of 1.0 lb provides the desired comfort to the handle strip and contributes to the mechanical stability of the handle.

[0015] In some embodiments, the nonwoven fabric is selected from nonwoven polymers, nonwoven bamboo, nonwoven jute, and nonwoven textiles.

[0016] As used herein, the term "nonwoven" refers to a material that includes a combination of long and short fibers that are bonded together through chemical, mechanical, thermal, and / or solvent processes. For example, examples of nonwovens are nonwoven polymers, nonwoven bamboo, nonwoven jute, or nonwoven textiles. Nonwovens provide handle strips that are easy for a user to grip and have good mechanical properties, such as tensile strength.

[0017] As used herein, the term "nonwoven polymeric" refers to a nonwoven fabric made from a polymer. Nonwoven fabrics made from polymeric materials may include polyester, acrylic, nylon, and / or polyolefin.

[0018] As used herein, the term "non-woven bamboo" refers to a non-woven fabric made from bamboo fibers. Non-woven bamboo is known to those skilled in the art.

[0019] As used herein, the term "nonwoven jute" refers to a nonwoven fabric made from jute fibers and / or jute waste. For example, the jute may be made by needlepunching or other methods suitable to those skilled in the art.

[0020] As used herein, the term "nonwoven textile" refers to nonwoven fabrics made from fibers such as wool, cotton, or regenerated cellulose.

[0021] In some embodiments, the reinforcing material has a density of 20 to 200 g / m 2 The reinforcing material improves the mechanical properties of the strip, such as strength and durability.

[0022] In some embodiments, the reinforcing material is selected from the list consisting of kraft paper, high density polyethylene, jute, paper, and textiles, hi some embodiments, the reinforcing material comprises FiberForm paper.

[0023] As used herein, the term "kraft paper" includes paper materials made from chemical pulp from the kraft process. Kraft paper is known to those skilled in the art. Kraft paper can provide a handle with desirable mechanical properties.

[0024] In this specification, the term "high density polyethylene" refers to polyethylene having a density of 0.930 to 0.970 g / cm 3 High density polyethylene (HDPE) has a high strength-to-density ratio, chemical resistance, and thermal stability. HDPE is known to those skilled in the art.

[0025] As used herein, the term "paper" refers to a material made from wood pulp or other fibrous materials. For example, wood pulp may be produced from virgin wood chips and / or recycled paper.

[0026] As used herein, the term "textile" refers to natural fibers such as cotton, flax, jute, bamboo, and / or regenerated cellulose; animal-derived fibers such as wool, silk; synthetic fibers such as polyester, acrylic, nylon, polyurethane, and / or polyolefin; or combinations thereof. Such fibers and additives, such as elastomers, UV absorbers, flame retardants, etc., are known to those skilled in the art.

[0027] As used herein, the term "jute" refers to natural bast fibers known to those skilled in the art.

[0028] In some embodiments, the strip has a width of 5-35 mm, such as 7-30 mm, 10-25 mm, etc. Strips with the above widths have suitable mechanical properties and are comfortable for the user. A strip that is too thin can dig into the user's hand, causing discomfort, while a strip that is too thick can be uncomfortable or virtually impossible for the user to grasp. The above widths can be the width of a folded or unfolded strip.

[0029] In some embodiments, the lower liner comprises paperboard. The paperboard lower liner provides a mechanically rigid base for the handle. Furthermore, the lower liner provides a lower surface of the upper liner and / or an upper surface to which the strip can be secured. The upper surface of the lower liner may be secured to the lower surface of the upper liner with an adhesive, for example, using a hot melt adhesive.

[0030] In some embodiments, the bottom liner and / or top liner have a width of 20 to 90 mm, such as 30 to 80 mm, 40 to 70 mm, etc. When a handle is used, e.g., when the handle is fastened to a box or package, the width of the bottom liner can create a contact surface between the handle and, e.g., the box, and provide good adhesion, reducing the risk of undesired removal of the handle from the box. The width of the top liner can create a contact surface between the top liner and the bottom liner, and provide good adhesion, reducing the risk of undesired removal, e.g., due to poor adhesion or adhesion.

[0031] The term "paperboard" is known to those skilled in the art and may refer to single or multi-ply paperboard. Paperboard is one of several factors that improve the mechanical properties of the handle.

[0032] In some embodiments, the lower liner has a thickness of 165 to 185 g / m 2 , 170~180g / m 2 etc. 160-190g / m 2 It has a weight of

[0033] In some embodiments, the top liner comprises a laminate material or kraft paper. The laminate material may comprise kraft paper.

[0034] In some embodiments, the bottom liner has a thickness of 100 to 500 μm, such as 150 to 450 μm, or 200 to 400 μm.

[0035] In some embodiments, the top liner has a thickness of 200 to 2500 μm, such as 300 to 2250 μm, 400 to 200 μm, etc. In one example embodiment, the top liner is composed of 2 to 5 layers, each layer having a thickness of 100 to 500 μm, such as 130 to 450 μm, 200 to 400 μm, etc. It will be understood by those skilled in the art from the present disclosure that it is possible to provide a top liner including one layer or six or more layers without departing from the concept of the present disclosure.

[0036] In some embodiments, the strip has a thickness of 300 to 2500 μm, such as 500 to 2500 μm, 600 to 2000 μm, 600 to 1200 μm.

[0037] In some embodiments, the first and second ends of the strip are secured to the top and bottom liners by adhesive means. For example, the adhesive means may be a polyethylene adhesive, 10-50 g / m 2 The adhesive may be a polyethylene adhesive having a weight of 100g. Securing the strip between the upper and lower liners improves load distribution, thereby reducing the risk of the strip falling off the upper and lower liners. This further improves the durability of the handle.

[0038] In some embodiments, the handle comprises: It further includes layer D comprising an adhesive and layer E comprising a paper cover material, with layer D being disposed on top of layer C and layer E being disposed on top of layer D to form a laminate.

[0039] Layer D provides a handle with improved mechanical properties, such as strength. Layer E provides a handle with improved mechanical properties, such as strength, and improved comfort. The improved comfort provided by Layer E is due, for example, to a composition that affects the overall perception of the strip. Additionally, the paper cover material of Layer E allows for aesthetic variations and a printable surface for branding, date stamps, tables of contents, etc. The paper cover material provides good bond-forming properties, such as wettability, improving the adhesive bond and mechanical properties of the strip.

[0040] As used herein, the term "paper cover material" refers to materials made from wood pulp or other fibrous substances such as different qualities of paper. For example, the paper cover material may be kraft paper.

[0041] In some embodiments, the paper cover material has a density of 20 to 160 g / m 2 , 30~140g / m 2 etc. 10~180g / m 2 It has a weight of

[0042] In some embodiments, Layer A is wrapped around Layers B and C, and optionally Layers D and E. By wrapping Layer A around Layers B and C, and optionally Layers D and E, a handle with improved comfort is provided because the user's hands primarily interact with Layer A during use of the handle, including at the side ends of the strip, which are typically areas that can dig into the user's hands when gripping the handle and cause discomfort. Thus, providing a nonwoven Layer A in this portion of the strip is particularly beneficial.

[0043] According to a second aspect of the present disclosure, there is provided a method for manufacturing a handle as described herein, the method including providing a lower liner, providing an upper liner, providing a strip, providing an adhesive, and combining the lower liner, the upper liner, the strip, and the adhesive to form the handle.

[0044] In some embodiments, providing the strip includes providing a layer A, a layer B, and a layer C, and stacking layers A-C to form the strip.

[0045] In some embodiments, layer A has a width greater than layers B and C, such that after lamination, the sides of layer A extend beyond the lateral edges of layers B and C, the sides of layer A wrap around layers B and C, and layer A provides substantially the entire outer surface of the strip.

[0046] In some embodiments of the method, after lamination, the method further comprises folding the strip so that layer A is disposed as substantially the entire outer surface of the strip.

[0047] Providing the strip further includes providing a layer D and a layer E, and sequentially stacking layers A through E to form the strip.

[0048] The advantages and features of the second aspect are largely the same as those described above for the first aspect. The descriptions provided for the first aspect are largely compatible with most of the second aspect. Furthermore, unless otherwise specified, it is understood that the concepts of the present disclosure relate to any and all combinations of features.

[0049] Further scope of applicability of the present disclosure will become apparent from the following detailed description. It will be understood, however, that the detailed description and specific examples, while indicating preferred embodiments of the present disclosure, are intended for purposes of illustration only, and that various changes and modifications within the scope of the present disclosure will be apparent to those skilled in the art from the detailed description.

[0085] Materials and Manufacturing Handle IH1 of an embodiment of the present disclosure was manufactured including a strip having Layer A comprising a nonwoven fabric, Layer B comprising a polyethylene adhesive, and Layer C comprising FiberForm paper. The strip was folded so that Layer A constituted the outer surface of the strip. The construction of the strip for IH1 is shown in Table 1.

[0086] Comparative handles CH1 and CH2 were manufactured, and the structures of handles CH1 and CH2 are shown in Table 1.

[0087] Handle IH1 of the present disclosure and comparative handles CH1 and CH2 had the handle structures described herein, with first and second ends of the strip secured between upper and lower liners. [Table 1]

[0088] Handle evaluation The handle IH1 of the present disclosure and the handles CH1 and CH2 of the comparative examples were compared by a load-bearing test. The results of the load-bearing evaluation are shown in Table 2. As a result, the inventors surprisingly discovered that the handle of the present disclosure exhibited higher load-bearing capacity than the handles of the comparative examples.

[0089] The load-bearing capacity test was performed by placing a handle on a surface and firmly securing the handle between the surface and a plate with an opening, so that the handle strip was accessible within the opening in the plate. In other words, the plate was positioned so that the handle was secured to the surface by applying pressure to the upper and lower liners with the plate.
