Abstract
Description
[Technical Field]
[0001] The present invention relates to a wet wipes package that contains wet wipes inside. [Background technology]
[0002] Patent Document 1 discloses a package having an oval, circular, rectangular, diamond-shaped, etc., dispensing opening and containing folded and stacked wet wipes inside. In this package, wet wipes can be taken out one by one by pinching the edge of the wet wipe with the fingers and pulling it out through the dispensing opening.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-60228 Summary of the Invention [Problem to be solved by the invention]
[0004] In the outlet of Patent Document 1, after the upper layer of wet wipes is pulled out, the tip of the next layer of wet wipes, which partially overlaps the upper layer of wet wipes, is also pulled out to the outside, continuing from the upper layer, but this often ends up being exposed more than necessary.
[0005] In this way, the next wet wipe with its tip exposed more than necessary cannot be returned to the package and must be pulled out and used as is, which often results in excess wet wipes being used and wasted.
[0006] An object of the present invention is to solve the above-mentioned problems and to provide a wet wipes package that does not expose the leading edge of the next layer of polymerized wet wipes more than necessary. [Means for solving the problem]
[0007] In order to achieve the above-mentioned object, the wet wipes packaging of the present invention is a wet wipes packaging having an opening for dispensing wet wipes on the top surface that is opened and closed by a sealing seal, and containing folded and overlapping wet wipes inside, characterized in that the opening is formed by an outline defined by a first curved portion that is an arc of a predetermined angle based on a predetermined center point, a second curved portion that is outside the first curved portion, has a radius of curvature larger than the radius of curvature of the first curved portion, and is roughly the same in shape as the first curved portion, and third and fourth curved portions that are approximately semicircular in shape and bulge outward, are located between both ends of the first and second curved portions, and have the width between the two ends as their diameter. [Effects of the Invention]
[0008] According to the wet sheet packaging of the present invention, the curved shape of the opening prevents the tip of the next layer of wet sheets from being exposed more than necessary when the upper layer of wet sheets is removed, and allows the stacked inner wet sheets to be removed one by one. [Brief explanation of the drawings]
[0009] [Figure 1] FIG. 2 is a perspective view of a wet wipe packaging body. [Figure 2] FIG. 2 is a perspective view of the wet wipes package with the sealing seal peeled off. [Figure 3] FIG. DETAILED DESCRIPTION OF THE INVENTION
[0010] The present invention will now be described in more detail with reference to the illustrated embodiments. Fig. 1 is a perspective view of a wet wipes package of the embodiment, and Fig. 2 is a perspective view of the package with the sealing seal peeled off. The package 1 is a bag body having a curved take-out opening 3 provided on an upper surface 2 and extending substantially parallel to the longitudinal direction of the package 1, and containing wet wipes S that are folded and stacked inside.
[0011] The size of the package 1 containing the wet wipes S is, for example, a roughly rectangular parallelepiped shape of about 18 cm wide, 10 cm long, and 3 cm high. The wet wipes S contained in the package 1 are made of polyester rayon, pulp rayon, etc., and have a basis weight of 30 g / m. 2 ~70g / m 2 A certain amount of nonwoven fabric is used.
[0012] A flexible sealing seal 4 that can be peeled off and attached around the outlet 3 is arranged on the top surface 2 of the package 1, and a base 4a of the sealing seal 4 is fixed to the top surface 2 by bonding. A tab 4b is provided at the tip of the sealing seal 4, and an adhesive material is applied to the back surface of the sealing seal 4 to facilitate peeling and attachment.
[0013] The package 1 is made of a flexible, airtight and / or liquid-tight laminated sheet film of PET-polyethylene, PET-polypropylene, or the like, and is configured such that the laminated sheet film, for example, about 62 μm thick, is shaped into a cylindrical shape with both ends sealed together, forming a roughly rectangular bag body consisting of a top surface 2, both side surfaces 5, and a bottom surface 6. The sealing seal 4 is further made of a resilient material.
[0014] Figure 3 is an explanatory diagram of the shape of the outlet 3. The outlet 3 originally has a cutout that is thinner than the surrounding film and follows the shape of the outlet 3, and a tear-off member 3' is provided through this cutout. The tear-off member 3' is then cut off by the sealing seal 4, forming the hole-shaped outlet 3.
[0015] The curved outlet 3 shown in Figure 3 is formed by an outline defined by a first curved portion 3a having a predetermined angle θ and a first radius of curvature r1, with a predetermined center point as the base point p1; a second curved portion 3b having a predetermined angle θ and a second radius of curvature r2 greater than the first radius of curvature r1, which is located outside the first curved portion 3a; and third and fourth curved portions 3c and 3d having an approximately semicircular shape that bulges outward and are provided between both ends of the first and second curved portions 3a and 3b, with the width between the two ends being a diameter r3.
[0016] The first and second curved portions 3a, 3b are both arc-shaped portions of a circle, and the base point p1, which is the center of the circle, coincides with each other. A line segment r4 connecting the centers of the semicircles of the third and fourth curved portions 3c, 3d is parallel to the longitudinal direction of the top surface portion 2 of the package 1, and the position of line segment r4 is positioned so as to substantially coincide with the center line of the stacked wet wipes S, which is parallel to the longitudinal direction.
[0017] Strictly speaking, the base points p1 of the first and second curved portions 3a, 3b do not have to coincide, and there is no significant problem as long as the shape of the second curved portion 3b is approximately the same as that of the first curved portion 3a.
[0018] The predetermined angle θ of the first and second curved portions 3a and 3b centered on the base point p1 is in the range of 40 to 50 degrees, the first radius of curvature r1 is, for example, 27 mm, and the second radius of curvature r2 of the second curved portion 3b is 37 mm.
[0019] The third and fourth curved portions 3c and 3d, which bulge outward and connect to the ends of the first and second curved portions 3a and 3b, respectively, have a semicircular diameter r3 of 10 mm. The diameter r3 corresponds to the difference between the first and second curvature radii r1 and r2, and the ratio of the diameter r3 to the first curvature radius r1 is 1 / 4 to 5 / 9.
[0020] The packaging body 1 contains a stack of wet wipes S made of nonwoven fabric, stacked so that the stack can be dispensed one by one from the outlet 3. Before use, a tear-off member 3' is connected to the outlet 3 by a thin film cut, the outlet 3 is covered by a sealing seal 4, and the part surrounding the outlet 3 is attached to the upper surface 2 with an adhesive.
[0021] To use the wet wipes S, the gripping portion 4b of the sealing seal 4 is picked up and peeled off from the top surface portion 2, and the cutting member 3' of the outlet 3 is torn from the outlet 3 by adhering to the adhesive on the back side of the sealing seal 4, and thereafter remains attached to the sealing seal 4.
[0022] A portion of the upper layer of wet wipes S that is visible inside the outlet 3 is pinched with the fingers and pulled upward. As a result of this pulling, the next layer of wet wipes S that is superimposed on the upper layer of wet wipes S is also pulled up, but the tongue 3e formed by the first curved portion 3a acts as resistance, so that the next layer of wet wipes S remains inside the package 1 except for a tip of a moderate length. For this reason, it is preferable that the material of the package 1 that constitutes the tongue 3e not only be flexible but also elastic.
[0023] The diameter r3 of the semicircles of the third and fourth curved portions 3c, 3d corresponds to the longitudinal width of the outlet 3, and this width is preferably uniform. If there is a portion of the outlet 3 whose width is greater than the diameter r3, that portion will weaken the resistance to the wet wipes S, making it difficult for the upper wet wipes S to be caught by the tongue piece 3e, and the tip of the next layer of wet wipes S pulled by the upper wet wipes S will be exposed more than necessary.
[0024] Conversely, if there is a part of the width of the outlet 3 that is smaller than the diameter r3, that part will provide strong resistance to the wet wipes S, making it difficult to pull out the upper layer of wet wipes S, and in some cases the wet wipes S may even tear.
[0025] For these reasons, in order to maintain the width of the diameter r3 in accordance with the shape of the tongue piece 3e that has an appropriate resistance, the first and second curved portions 3a, 3b must be substantially parallel and have substantially the same shape. Furthermore, by making the third and fourth curved portions 3c, 3d semicircular, the side edges of the wet wipes S are prevented from being caught on both ends of the dispensing opening 3 and being torn.
[0026] In this way, only the upper layer of wet wipes S is taken out through the outlet 3, leaving the tip of the next layer of wet wipes S moderately exposed from the outlet 3. When the wet wipes package is finished being used and the sealing seal 4 is attached, the wet wipes S that were previously the next layer become the upper layer, the package 1 is sealed, and the moisture and alcohol in the wet wipes S inside are prevented from drying out. In this way, when the upper layer of wet wipes S is taken out, the tip of the next layer of wet wipes S that is also pulled out is not exposed more than necessary due to the presence of the tongue piece 3e.
[0027] Thus, according to the wet sheet packaging of the present invention, the shape of the curved outlet 3 prevents the tip of the wet sheet S of the next layer from being exposed more than necessary when the upper layer of wet sheet S is removed, and the stacked inner wet sheets S can be removed one by one.
