[[Prior Art Documents]] [[Patent Documents]]
[0003] [[Patent Document 1]] Japanese Patent No. 3659792 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]
[0004] In the case of the sheet package of Patent Document 1 mentioned above, since the lid member attached to the package is peeled off along the longitudinal direction thereof, when taking out the wet sheet, the user holds the package with one hand and peels the lid member with the other hand to expose the take-out port. However, a two-stage peeling operation is required: after peeling the front half portion of the lid member to expose the front half side of the take-out port, the rear half portion of the lid member is peeled off to expose the rear half side of the take-out port.
[0005] An object of the present invention is to provide a sheet package in which the take-out port can be easily exposed for taking out a wet sheet. [[Means for Solving the Problem]]
[0006] To solve the above problems, the invention described in claim 1 is: A sheet packaging in which a sheet laminate, consisting of multiple wet wipes stacked together, is packaged by a packaging body, The packaging has an opening for taking out the wet wipes, and a seal-like lid material that can be repeatedly adhered to and peeled off is attached to the position covering the opening.

[0014] Hereinafter, embodiments of the sheet package according to the present invention will be described in detail with reference to the drawings. However, although various technically preferable limitations are given to the embodiments described below for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples. In the following description, as shown in Fig. 1, the front-rear direction, left-right direction, up-down direction, and the X-axis, Y-axis and Z-axis are defined for explanation. That is, in the sheet package 100, the side where the lid member 110 is attached is defined as upper, the opposite side is defined as lower, the side where one of the end seal portions 121 of the sheet package 100 is formed is defined as right, and the side where the other end seal portion is formed is defined as left. When the right end seal portion 121 is arranged on the near side, the left hand side is defined as front, the right hand side is defined as rear, the axis along the front-rear direction is the X-axis, the axis along the left-right direction is the Y-axis, and the axis along the up-down direction is the Z-axis. In Fig. 1, the side where the tab portion 11 is provided on the lid member 110 is the front side.
[0015] [Sheet Package] In the sheet package 100 of the present embodiment, for example, as shown in Figs. 1 to 5, a sheet laminate in which a plurality of wet sheets P are stacked is wrapped by a package 120 formed of a film, and the wet sheets P are accommodated in the package 120. The package 120 is formed with a take-out port 12 for taking out the wet sheets P, and a seal-shaped lid member 110 capable of repeating adhesion and peeling a plurality of times is attached at a position covering the take-out port 12.
[0016] [Wet Sheets] Wet wipes P are sheets impregnated with a liquid medicine, and include, for example, wet tissues, toilet cleaners, antiperspirant wipes, kitchen cleaners, etc. The sheet material of the wet sheet P is preferably a nonwoven fabric manufactured using a predetermined fiber as the fiber material by a well-known technique such as spunlace, air-through, air-laid, point bond, spunbond, or needle punch. Examples of specified fibers include cellulose fibers such as rayon, lyocell, Tencel, and cotton; polyolefin fibers such as polyethylene, polypropylene, and polyvinyl alcohol; polyester fibers such as polyethylene terephthalate and polybutylene terephthalate; and polyamide fibers such as nylon. These may be used individually or in combination of two or more types. Furthermore, the sheet material for the wet sheet P is preferably formed with a basis weight of 30 to 80 gsm and a size of 100 mm to 200 mm in the MD direction (the direction in which the paper moves on the paper machine) and 100 mm to 200 mm in the CD direction (the direction perpendicular to the direction in which the paper moves on the paper machine). Note that basis weight refers to the basis weight measured according to JIS P 8124:2011. Furthermore, any liquid solution can be used as the impregnation of the wet wipe P, depending on the intended use of the wet wipe P, but it is preferable to use one that contains, for example, purified water, a preservative, a pH adjuster, etc.
[0017] [Packaging] The packaging 120 is formed in the shape of a bag using a sheet of film. As the sheet-like film, for example, single or composite materials of synthetic resin films such as polyethylene, polypropylene, polyethylene terephthalate, polyester, polyamide, and polyvinyl chloride can be used, or composite films made by laminating these synthetic resin films with aluminum foil or paper can be used. The thickness of the sheet-like film is preferably 40 μm to 70 μm. This packaging 120 is formed by joining opposite sides of a sheet-like film to form a center seal portion (formed on the lower side of the packaging 120) (not shown), then placing the sheet laminate inside the tubular film, and finally joining the openings at both ends of the tubular film to form two end seal portions 121, 121, thereby creating a pillow-shaped packaging that encloses the sheet laminate. The size of the packaging 120 is determined according to the size of the sheet stack to be contained, but it is preferable that the packaging 120 be large enough to accommodate the sheet stack with some extra space, without making it unnecessarily large, and without making it difficult to remove the wet wipes P when in use. Furthermore, the packaging body 120 has a roughly rectangular shape in plan view, and its long, horizontal dimension is preferably 130 mm to 300 mm, while its short, front-to-back dimension is preferably 70 mm to 120 mm. More preferably, the longer left-right dimension is 230mm to 250mm, and the shorter front-to-back dimension is 100mm to 120mm.
[0018] [Lid material] The lid material 110 is formed from a separate sheet piece from the packaging body 120 and is configured to cover the dispensing opening 12 from which the wet sheets P are taken out, so that it can be opened and closed. The shape of the lid 110 is not particularly limited as long as it can completely cover the outlet 12; in this case, a roughly rectangular lid 110 is used. The roughly rectangular lid material 110 is attached to the upper surface of the packaging body 120, which has a roughly rectangular shape in plan view, for example, as shown in Figure 5, with the longitudinal direction of the packaging body 120 and the longitudinal direction of the lid material 110 aligned. Furthermore, as will be described later, a wide opening 12 is formed on the upper surface of the packaging 120, along the left-right direction which is the longitudinal direction of the packaging 120. Therefore, the lid material 110 that covers the opening 12 is also formed in a roughly rectangular shape that is long in the left-right direction and is attached to the upper surface of the packaging 120. The longer left-right dimension of the lid material 110 is preferably 70mm to 100mm, and the shorter front-to-back dimension is preferably 35mm to 65mm. More preferably, the longer left-to-right dimension is 75mm to 85mm, and the shorter front-to-back dimension is 50mm to 60mm. Furthermore, a knob 11 is provided on one end of the lid material 110, protruding from its end. The knob portion 11 is provided in such a manner that it protrudes from the long edge of the lid material 110. The short front-to-back dimensions of the lid material 110 described above refer to the dimensions of the lid material 110 excluding the tab 11. As will be described later, the tab 11 is a part that is not attached to the packaging body 120, so its dimensions are distinguished from those of the main body of the lid material 110.
[0019] The lid material 110 is formed in a manner in which a lid material body sheet 110a and a laminate sheet 110b covering the surface side of the lid material body sheet 110a are laminated together, as shown in Figures 2 and 4, for example. The material used for the sheet pieces constituting the lid body sheet 110a is the same as the material used for the film constituting the packaging body 120. The thickness of the sheet pieces constituting the lid body sheet 110a is preferably thicker than the film constituting the packaging body 120, and is between 60 μm and 80 μm. For example, a transparent polyvinyl chloride resin film can be used for the laminate sheet 110b, and this transparent laminate sheet 110b is attached to the surface of the lid material body sheet 110a with a transparent adhesive. The laminate sheet 110b has a size that extends from the lid material body sheet 110a to the other end of the lid material 110, and at the other end of the lid material 110, the laminate sheet 110b portion is adhered to the packaging body 120. The thickness of the laminate sheet 110b is approximately 50 μm.
[0020] The back surface of the lid material 110 is coated with a pressure-sensitive adhesive such as polyester, acrylic, or rubber, and the lid material 110 can be repeatedly bonded and peeled off, and is bonded to the packaging body 120 so as to be able to open and close the dispensing opening 12. Furthermore, the other end of the lid material 110 has a laminate sheet 110b portion that is adhered to the packaging body 120, and it is preferable that this laminate sheet 110b portion is adhered with a pressure-sensitive adhesive that has stronger adhesive strength than the pressure-sensitive adhesive that adheres to the lid material body sheet 110a of the lid material 110. This makes it difficult for the laminate sheet 110b portion of the lid material 110 to peel off where it is adhered to the packaging body 120, and the other end of the lid material 110 functions as a fixing portion 111 of the lid material 110. This fixing portion 111 is provided along the width direction (left-right direction) of the long side, which is the other end of the lid material 110. Furthermore, pressure-sensitive adhesive is not applied to the underside of the knob 11 provided on one end of the lid material 110, and the knob 11 is not adhered to the packaging body 120. This makes it easy to open and close the lid material 110 using the knob 11.
[0021] Such a lid material 110 is designed to be peeled off starting from the knob portion 11 at one end and towards the fixing portion 111 at the other end of the lid material 110. In other words, the lid material 110 is designed to be peeled off along the shorter side of the lid material 110. Specifically, the lid material 110 is configured to peel off in the opening direction along the shorter peeling length of the lid material 110, in order to expose the outlet 12. Furthermore, when the outlet 12 covered by the lid material 110 is used as a reference, the lid material 110 is configured to peel off in the opening direction along the direction (front-to-back direction) where the width of the outlet 12 is narrower, in order to expose the outlet 12.
[0022] Furthermore, on the other end of the lid material 110, there is a region where the laminate sheet 110b is adhered to the packaging body 120, and the thickness of the lid material 110 is thin in the width direction (left-right direction) of the lid material 110. Specifically, the lid material 110 has a first region in which the lid material body sheet 110a and the laminate sheet 110b are laminated together, and a second region consisting only of the laminate sheet 110b. The thickness of the lid material 110 differs between the first and second regions, with the second region being the thinner region of the lid material 110. The fixing portion 111 of the lid material 110 corresponds to the second region where the thickness of the lid material 110 is thin. Furthermore, the lid material 110 has a boundary portion 112 that corresponds to the boundary between the first region and the second region. The boundary portion 112 of this lid material 110 functions as a hinge portion of the lid material 110, as will be described later.
[0023] [Outlet] The top surface of the packaging body 120 has an opening 12 that has a shape in which the width in one direction (front to back) is wider than the width in one direction (front to back) in another direction (left to right). In this embodiment, the outlet 12 in Figure 3 has a roughly oval shape, with a width in the left-right direction perpendicular to the front-to-back direction being wider than the width in the front-to-back direction, and in this case, it has a roughly rounded rectangular shape. In order to make it easier to remove the wet wipes P contained in the packaging 120, which has a roughly rectangular shape in plan view and is long in the left-right direction, the dispensing opening 12 is formed to be wide in the left-right direction. The width of the outlet 12 in the front-to-back direction is preferably 15 mm to 30 mm, and the width in the left-to-right direction is preferably 30 mm to 60 mm. For example, the top surface of the packaging body 120 is provided with a cutting line for forming the dispensing opening 12. When the sheet packaging body 100 is first used, the lid material 110 is peeled off from the packaging body 120, and the portion corresponding to the cutting line is separated by the adhesive force of the pressure-sensitive adhesive provided on the back surface of the lid material 110, thereby forming the dispensing opening 12.
[0024] [Procedure for removing the lid material] Next, the procedure for peeling off the lid material 110 in order to remove the wet sheet P from the sheet packaging 100 of this embodiment will be described. This section explains the process using the example of removing a wet sheet P from a sheet package 100 that is placed on a designated stand, such as a workbench or table.
[0025] When peeling off the lid material 110 of the sheet packaging 100 in order to take out the wet sheet P from the sheet packaging 100 placed on the display stand, for example, as shown in Figure 6, the user grasps the tab portion 11 of the lid material 110 with the fingers of one hand (in this case, the thumb and index finger of the right hand) and presses down on the fixing portion 111 of the lid material 110 with the outer edge of the palm of that hand. Next, the user holds down the adhesive portion 111 with the outer edge of their palm, and with that hand, supports the sheet packaging 100 by pressing it down onto the mounting platform. Then, they peel the lid material 110 away from the packaging 120 by pulling it up from the side of the gripping portion 11, and peeling the lid material 110 off from one end. The peeling of the lid material 110 from one end is performed as a series of operations. For example, as shown in Figure 7, when the lid material 110 is peeled down to the boundary 112, the thickness of the lid material 110 changes, which changes the resistance to peeling the lid material 110. At that point, the user is instructed to stop peeling the lid material 110.
[0026] Then, when you release the lid material 110, which has peeled off up to the boundary 112, by turning it over, the now thinner boundary 112 acts as a hinge, causing the lid material 110 to bend and fall over under its own weight, as shown in Figure 3, for example. With the fixing portion 111 of the lid material 110 adhered to the packaging body 120, the lid material 110, which has bent and fallen over at the boundary portion 112, will not return to the closed position due to restoring force, and will therefore maintain a state in which the dispensing opening 12 is exposed. This makes it easier to remove the wet wipes P from the exposed outlet 12.
[0027] After using the wet wipes P, the user rotates the lid material 110 in the closing direction so that it returns to the top surface of the packaging body 120, and adheres the lid material 110 to the top surface of the packaging body 120 so that it closes the dispensing opening 12, thereby preventing the wet wipes P from drying out (see Figure 1).
[0028] In this way, by pressing the fixing portion 111 with the outer edge of the palm of the hand that is gripping the pinch portion 11, and supporting the sheet packaging body 100 on the mounting table, and then peeling off the lid material 110 by rotating the palm using the outer edge of the palm pressing down on the fixing portion 111 as a pivot point, the lid material 110 of the sheet packaging body 100 can be peeled off with a single motion using one hand, exposing the dispensing opening 12. In particular, the lid material 110 of the sheet packaging body 100 in this embodiment is configured to peel off in an opening direction that aligns with one direction (front-to-back direction) where the width of the dispensing opening 12 is narrow, and in an opening direction that aligns with the direction in which the peeling length of the lid material 110 is short. Therefore, it is easy to peel off the lid material 110 in a single operation to expose the dispensing opening 12. In other words, the lid material 110 of the sheet packaging 100 can be peeled off with one hand to expose the dispensing opening 12 and make it possible to take out the wet sheet P. As described above, the sheet packaging 100 of this embodiment has a structure that makes it easy to expose the dispensing opening 12 in order to take out the wet sheet P.
[0029] As mentioned above, the dimensions of the lid material 110 of the sheet packaging body 100 in this embodiment in the shorter direction are preferably 35 mm to 65 mm, and particularly preferably 50 mm to 60 mm. If the dimensions of the lid material 110 in the shorter direction (front-to-back direction) are of this size, the peeling length required to expose the outlet 12 is suitable, so the lid material 110 can be easily peeled off with one hand to expose the outlet 12 and take out the wet wipe P.
[0030] However, the present invention is not limited to the embodiments described above. In the lid material 110 of the sheet packaging body 100, one end of the lid material 110 on which the tab portion 11 is provided may be formed to be shorter in width than the other end of the lid material 110 on which the fastening portion 111 is provided. Here, one end of the lid material 110 refers to the portion excluding the tab portion 11. For example, as shown in Figure 8, the lid material 110 may have an edge on one end that is formed in an arc shape when viewed from above. Furthermore, as shown in Figure 9, the lid material 110 may have a roughly trapezoidal shape in plan view, and the width in the left-right direction on one end of the lid material 110 with the knob portion 11 is shorter than the width in the left-right direction on the other end with the fastening portion 111. With this type of lid material 110, when peeling the lid material 110 from the knob side 11, the initial width of the lid material 110 is relatively short, resulting in relatively weak resistance when peeling the lid material 110. Therefore, the action of starting to peel the lid material 110 with one hand can be performed relatively smoothly. With such a sheet packaging 100, the lid material 110 can be more easily peeled off with one hand to expose the dispensing opening 12 and allow the wet sheet P to be taken out.
[0031] Furthermore, the present invention is not limited to the embodiments described above. For example, as shown in Figures 10 to 12, the packaging body 120 may have an opening 12 formed on its upper surface, a lid material 110 attached from the upper surface of the packaging body 120 to the side surface in contact with that upper surface, and the boundary portion 112 of the lid material 110 is aligned along the edge between the upper surface and the side surface of the packaging body 120. In this sheet packaging 100, the fixing portion 111 of the lid material 110 is adhered to the side surface of the packaging 120.
[0032] When the lid material 110 of this sheet packaging 100 is peeled off to the boundary portion 112, for example as shown in Figure 12, the boundary portion 112 functions as a hinge portion, causing the lid material 110 to bend and fall down due to its own weight. At this time, the lid material 110 tilts down to the side of the packaging body 120, and the lid material 110 is positioned below the top surface of the packaging body 120, making it difficult for the user's hand to touch the lid material 110 when taking out the wet wipe P from the dispensing opening 12.
[0033] For example, if the peeled-off lid 110 is upside down on the top surface of the packaging 120 (see Figure 3), the user's hand may touch the underside of the lid 110 when taking out the wet wipes P from the opening 12. Since pressure-sensitive adhesive is applied to the underside of the lid 110, the lid 110 may stick to the user's hand, making it difficult to take out the wet wipes P. In this case, you have to peel off the lid material 110 that is stuck to your hand, which is troublesome when you want to use the wet wipe P in a hurry.
[0034] Thus, if the sheet packaging 100 is such that the peeled-off lid material 110 collapses to the side of the packaging body 120 and the lid material 110 is positioned below the top surface of the packaging body 120, the problem of the lid material 110 sticking to the user's hand can be reduced, making it suitable for use as a sheet packaging 100 that makes it easy to take out the wet wipes P from the dispensing opening 12.
[0035] Furthermore, when peeling the lid material 110 from the sheet packaging 100 to which the lid material 110 is attached with one hand, the user can press down on the edge of the top surface of the packaging 120 so as to press down on the boundary 112 along the fixing portion 111 of the lid material 110 with the outer edge of the palm of the user's hand, thereby peeling off the lid material 110 and exposing the dispensing opening 12 in the same manner as the procedure for peeling off the lid material 110 described above.
[0036] The application of the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of symbols]
