Description

[Technical Field]

[0001] This invention relates to a wiper storage carton in which wipers used for cleaning work and the like are stored in a removable storage box. [Background technology]

[0002] Wipers made of paper sheets or similar materials need to meet requirements for wiping performance, liquid absorption performance, and durability, and wiper storage cartons, which house such wipers in a storage box with an opening, have been proposed for some time. Patent documents 1 and 2 disclose a so-called pop-up type wiper storage carton in which a resin film having slits in the longitudinal direction is fixed to an outlet on the top surface, and the wipers are removed from that outlet. A pop-up type refers to a system in which the sheet is continuously folded so that the removal of the upper wiper induces the pulling out of the lower wiper. In this configuration, the wipers can be sequentially kept protruding from the outlet, making them easy to remove, and the resin film has the advantage of preventing dust and other debris from entering.

[0003] On the other hand, there are also wiper storage cartons that consist of wipers with pre-folded sheets stored individually in storage boxes. Patent Document 3 discloses a configuration in which a wiper made of a sheet folded in half is stored in a storage box having an openable and closable lid that spans a wide area across the top panel and the front panel. This type of wiper storage carton has a large opening that spans the top and front panels, allowing multiple wipers to be removed at once. This is highly convenient in environments where folded wipers are often used in bundles. [Prior art documents] [Patent Documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2021-54445 [Patent Document 2] Japanese Patent Publication No. 2004-18010 [Patent Document 3] Patent No. 6830838 [Overview of the Initiative] [Problems that the invention aims to solve]

[0005] However, in the case of pop-up type wiper storage cartons disclosed in Patent Documents 1 and 2, the wipers are always pulled out in an extended state from the opening. Therefore, when there is a large amount of liquid to wipe or a large area to clean, it becomes necessary to pull out the wipers from the opening three to four times and then stack or fold them, which presents an additional challenge.

[0006] On the other hand, in the case of wiper storage cartons disclosed in Patent Document 3, etc., if you want to unfold the folded wipers to perform cleaning work, you will need to go through the trouble of unfolding them. If the wipers are folded only twice, as disclosed in Patent Document 3, it is not much trouble, but if the wipers are folded multiple times, such as four times or six times, it is cumbersome to unfold them each time. Furthermore, in the case of this type of wiper storage carton, a large opening is often formed to reduce resistance and make it easy to take out the wipers, but it has been pointed out that this makes it easy for dust and dirt to get in, which is unhygienic.

[0007] In summary, when the work often involves using a single wiper unfolded, a pop-up type wiper storage carton is often used, while when multiple folded wipers are used, a wiper storage carton like the one disclosed in Patent Document 3, etc., is often used. However, many tasks involve a combination of the two usage patterns described above. In such cases, the only options were to either prepare both types of wiper storage cartons and use them appropriately for each task, or to prepare only one type of wiper storage carton and go through the trouble of stacking and folding multiple wipers and unfolding them according to each usage pattern while performing cleaning tasks.

[0008] This invention was made to solve the above-mentioned problems. The objective of the present invention is to provide a wiper storage carton that allows for the removal of multiple wipers according to the user's usage patterns from a single wiper storage carton, while simultaneously ensuring ease of removal of the wipers and maintaining hygiene by suppressing the inclusion of dust and dirt. [Means for solving the problem]

This is the gist of the present invention. [Advantages of the Invention]

[0014] With this invention, we have been able to provide a wiper storage carton that allows users to take out multiple wipers according to their usage patterns from a single carton, while simultaneously ensuring ease of removal of the wipers and maintaining hygiene by suppressing the inclusion of dust and dirt. [Brief explanation of the drawing]

[0015] [Figure 1] This is a perspective view showing the wiper storage carton in use, with the wipers stored in the storage box. [Figure 2] This is a perspective view of the storage box according to this embodiment, taken from the front, with the first lid open and before opening the first and second openings. [Figure 3] This is a perspective view of the storage box according to this embodiment, showing the state in which the perforations of the first and second openings have been broken from the state in Figure 2 to form the first and second openings, respectively. [Figure 4] (a) and (b) are perspective views showing how a sheet is folded into quarters to form a single wiper. [Figure 5] This diagram shows multiple four-fold wipers stacked together and is an explanatory diagram for illustrating the direction in which the wipers are removed from the second opening. [Figure 6] This diagram shows multiple six-fold wipers stacked together and is an explanatory diagram for explaining the direction in which the wipers are removed from the second opening. [Figure 7] This is an example of an exploded view of the storage box according to this embodiment. [Modes for carrying out the invention]

[0016] Hereinafter, with reference to the drawings, a wiper storage carton, which is one embodiment of the present invention, will be described in detail. Figure 1 is a schematic perspective view showing the appearance of the wiper storage carton 1 in use. In the explanation of the storage box 4 in Figures 1 to 3, the horizontal direction of the storage box 4 is the direction indicated by arrow X in Figure 1. The vertical direction of the storage box 4 is the direction perpendicular to the horizontal direction in a plan view, and is indicated by arrow Y in Figure 1. The height direction of the storage box 4 is the direction perpendicular to both the horizontal and vertical directions, and is indicated by arrow Z in Figure 1. The stacking direction of the wipers 2 is the height direction.

[0017] The wiper storage carton 1 is a product in which wipers 2, which are formed by folding sheets 3, are stored in a storage box 4 that has two outlets for the wipers 2, stacked on top of each other. Unlike so-called pop-up type wipers, each wiper 2 is independently constructed in the folding of the sheet 3, and each wiper 2 can be removed individually.

[0018] <Storage box 4> As shown in Figures 1-3 and Figure 7, the storage box 4 is a box whose basic shape is a cube or rectangular prism. Of its six faces, a first opening 5a is provided in the top surface 5 for removing the wiper 2 from above, and one of the four sides viewed from the top surface 5a is designated as the front surface 6, on which a second opening 6a is provided for removing the wiper 2 from the side. This configuration gives the storage box 4 six faces: the top surface 5 with the first opening 5a, the front surface 6 with the second opening 6a, the back surface 7 (see Figure 7), the bottom surface 8 (see Figure 7), the right side surface 9, and the left side surface 10. By configuring the first opening 5a and the second opening 6a as separate retrieval points, the user can consciously choose the method of retrieval. Furthermore, the storage box 4 is provided with a first lid 11 that covers the first opening 5a and a second lid 12 that covers the second opening 6a.

[0019] As shown in Figures 2 and 3, the first opening 5a is formed by creating an opening region 5c within the top surface 5, surrounded by perforations 5b all around, and then breaking through this opening region 5c. The first opening 5a is formed in the center in both the horizontal and vertical directions. While a rounded rectangle is often used as the planar shape of the first opening 5a, various other shapes, such as a barrel shape, can be selected as appropriate. The outer circumference of the first opening 5a is formed to be smaller in both the lateral and vertical directions than the outer circumference of the folded wiper 2 stored in the storage box 4.

[0020] The second opening 6a is formed by creating an opening region 6c surrounded by perforations 6b, excluding the hinge portion 13 which is made up of fold lines, and then breaking this opening region 6c. The second lid portion 12 is thus formed by the opening region 6c that swings at the hinge portion 13. The second opening 6a is located in the center of the front surface 6 in the lateral direction. The first lid portion 11 is shown as a lid portion that is large enough to cover almost the entire top surface 5.

[0021] Figure 7 is an example of an exploded view of the storage box 4 described above. The storage box 4 will be further explained using this exploded view. In the unfolded view, the front 6, left side 10, rear 7, and right side 9 are arranged in that order from right to left in Figure 7, and a top surface 5 with a first opening 5a is provided at the upper end of the front 6. A first lid portion 11 is provided at the upper end of the back surface 7, and the fold between the back surface 7 and the first lid portion 11 functions as a hinge portion 16 of the first lid portion 11.

[0022] A locking projection 14 is provided at the upper end of the first lid portion 11, and the first lid portion 11 is closed by inserting it into a stopper notch 15 provided between the front surface 6 and the top surface 5. On the other hand, a locking projection 17 is provided on the lower side of the second lid 12, and by inserting it into the notch at the lower position of the front surface 6, the second lid 12 is closed.

[0023] As shown in Figure 7, a pair of left and right insertion pieces 23 can also be provided on the top surface 5. These insertion pieces 23 are provided as needed to prevent the top surface 5 from opening in accordance with the wiper 2 when removing the wiper 2 from the first opening 5a, for example, when the wiper 2 is thick, as considerable force is applied to the top surface 5 when removing the wiper 2.

[0024] The first lid 11 can also be constructed as a lid with a hinge 13 and perforations 6b, similar to the second lid 12. However, having the first lid 11 separate from the top surface 5 where the first opening 5a is formed makes it easier to pull out the wiper 2 upwards, as the presence of the first lid 11 does not get in the way. In addition, when pulling out the wiper 2 upwards, the force applied to the top surface 5 around the first opening 5a can be made uniform, suppressing problems such as snagging that occur when pulling it out.

[0025] The width of the front 6 of the wiper storage carton 1 is set to be between 150 mm and 200 mm, the width of the first opening 5a is set to be between 55% and 90 mm of the width of the front 6, and the width of the second opening 6a is set to be between 70% and 90% of the width of the front 6. By setting the width within these ranges, the first opening 5a can be used as an opening suitable for picking up the folded sheet 3. Furthermore, the second opening 6a is configured to allow the sheet 3 to be picked up by grasping its edge and pulling it towards the user, and the above ranges allow for use that is suitable for each type of pick-up.

[0026] Furthermore, it is preferable that the area of ​​the first opening 5a is 35% to 80% of the area of ​​the top surface 5, the area of ​​the second opening 6a is 30% to 60% of the area of ​​the front surface 6, and the area of ​​the first opening 5a is larger than the area of ​​the second opening 6a. The reason is that when the composite non-woven fabric is folded four or more times, since the sheet 3 has a strong waist, when taking out the upper surface of the sheet 3 from the first opening 5a, an opening wider than a storage box for a general paper wiper or the like is preferable. However, if the area is large, the dust-proof property deteriorates. Therefore, by setting the opening area within the above range, a balance between the ease of removal and the dust-proof property can be obtained. Also, if the ratio of the second opening 6a exceeds 60%, there is a possibility that it will interfere with maintaining the strength during use of the storage box 4, which is not preferable.

[0027] <Wiper 2> As an example of the composite non-woven fabric employed in the present embodiment, a composite non-woven fabric in which a pulp fiber web is laminated on a spunbond non-woven fabric and integrated is preferable. Such a non-woven fabric is preferably one in which pulp fibers are water-stream entangled with the spunbond non-woven fabric by a water jet to form a pulp fiber web. This composite non-woven fabric preferably has a basis weight of 50 g / m 2 or more and 130 g / m 2 or less. Also, the spunbond non-woven fabric preferably has a basis weight of 10 g / m 2 or more and 30 g / m 2 or less, and the pulp fiber web preferably has a basis weight of 40 g / m 2 or more and 100 g / m 2 or less. The weight composition ratio of the spunbond non-woven fabric and the pulp fiber web is preferably set to 40 / 60 wt% or more and 10 / 90 wt% or less. The weight of the spunbond non-woven fabric is configured to be 10 g / m 2 or more and 30.0 g / m 2 or less, and includes a plurality of fusion points for connecting the spun resin fibers, and the shape of the fusion points is not limited. Circular, elliptical, polygonal, etc. are common. In this case, the area of one fusion point is 0.10 mm 2 or more and 0.50 mm 2 or less, the area ratio per unit area of the fusion points is 7% or more and 20% or less, and the number is 10 pieces / cm 2 or more and 150 pieces / cm 2 or less, which is preferably set. The material of the spunbond nonwoven fabric is selected from one of the following: nylon, vinylon, polyester, acrylic, polyethylene, polypropylene, or polystyrene, or a mixture of two or more of these materials. Polypropylene is preferably used. The pulp fiber web is preferably made of fibers from bleached coniferous kraft pulp selected from the group consisting of radiata pine, slush pine, southern pine, lodgepole pine, spruce, and Douglas fir. As the wiper 2 used in this embodiment, a spunlace-type composite nonwoven fabric can also be used. More specifically, the spunlace-type composite nonwoven fabric (a nonwoven fabric made of a natural fiber web and a synthetic fiber web) is a spunbond nonwoven fabric of 10 g / m² as the base material. 2 ~30g / m 2 Natural fiber web with 40g / m² pulp 2 ~100g / m 2 This is a nonwoven fabric formed by laminating these materials and entangling them with water jets. Alternatively, this composite nonwoven fabric can be used as a base sheet, with a heat-sealable sheet material sandwiched between two of these base sheets. More specifically, it can be a structure in which synthetic fiber webs are arranged facing each other, with a heat-sealable sheet material sandwiched between them, and the heat-sealable sheet material and the fibers constituting the synthetic fiber webs are integrated through melted and solidified joints (laminated structure). The basis weight of the base sheet used in wiper storage carton 1 is 320 g / m². 2 That's all. 450g / m 2 Preferably, the basis weight of the sheet material is 50 g / m². 2 That's all. 130g / m 2 The following is preferable:

[0028] <Extraction of wiper 2 from the first opening 5a> When you want to take out one wiper 2 at a time, you can take out the wiper 2 from the first opening 5a, which will pinch the area near the center of the top sheet 3. Since each wiper 2 is independent in its folding position, the user can easily and reliably take out one wiper 2 at a time. In other words, if the user wishes to take out the wipers 2 one by one, like a pop-up type, they can simply pull out the wipers 2 from the first opening 5a. Furthermore, with this configuration, the first opening 5a is surrounded by the paper material of the top surface 5, and the direction of removal is limited to upward only. Unlike the case where a large removal opening is formed as disclosed in Patent Document 3, the removal state when removing one sheet at a time can be made almost uniform. In contrast, with the configuration described in Patent Document 3, people often reach into the large opening to take out the wipers without thinking, which can lead to problems such as taking two wipers instead of one and returning the extra wipers to the storage box.

[0029] <Extraction from the second opening 6a and the folded state of sheet 3> As described above, the wiper 2 is made by folding sheet 3. There are various ways to fold sheet 3 to make individual wipers 2, but in this embodiment, we will explain using the case where four or more wipers 2 are used by folding sheet 3 as an example. When creating the four-fold shown in Figure 5, the first folded edge 31 is formed by folding the sheet in half along the first fold line 30, as shown in Figures 4(a) and 4(b). On the opposite side of the first folded edge 31, two open sheet ends 32 are formed.

[0030] Next, as shown in Figures 4(a) to 4(b), the sheet is folded in half along the second fold line 33, forming the second folded edge 34. On the opposite side of the second folded edge 34, the four sheet edges 32 are overlapping in an open state. To the right of the second folded edge 34, the two first folded edges 31 remain, while to the left, the four sheet edges 32 are overlapping in an open state. In the case of a four-fold, the number of folds is two, so the second folded edge 34 becomes the final folded edge 35 described above.

[0031] When stacking multiple wipers 2 inside the storage box 4, aligning the orientation of the final folded edges 35 ensures that the conditions for removing them from all directions are the same. In particular, when the final folded edge 35 is positioned to face the second opening 6a, that is, when the final folded edge 35 faces the second opening 6a, multiple final folded edges 35 become visible from the second opening 6a, making it easier to count the number of wipers 2 and convenient when taking out the required number. Furthermore, since the user only needs to grasp the final folded edge 35, one or more wipers can be reliably pulled out. If this type of usage is desired, when creating the wiper storage carton 1, stack the wipers with the final folded edge 35 facing the second opening 6a.

[0032] On the other hand, if an intermediate folding edge 36, such as the first folding edge 31, or an open sheet end 32, is located in the second opening 6a, rather than the final folding edge 35, it becomes more difficult to reliably remove a predetermined number of sheets compared to an arrangement where the final folding edge 35 faces the second opening 6a. However, this configuration has the advantage that the sheet 3 can be smoothly unfolded after being picked up by grasping the intermediate folding edge 36 or the sheet end 32. This is because the sheet 3 tends to unfold naturally as it is pulled out. In Figures 5 and 6, reference numeral 37 indicates the stacking direction of the wipers, and represents the height direction.

[0033] The above considerations also hold true for the six-fold configuration shown in Figure 6. In the case of other folding types as well, the way the wiper 2 removes the sheet can be changed depending on whether the direction of the final folded edge 35 of the sheet 3 in its folded form is directed toward the second opening 6a or toward a different direction from the second opening 6a. By providing the first opening 5a and the second opening 5b separately in this way, and setting the orientation in which the wipers 2 are stacked, the user can easily select how to remove the wipers 2 from a single storage box 4, depending on how they use the wipers 2. [Examples]

[0034] The present invention will be described in detail below with reference to examples used to determine the scope of each of the above-mentioned examples. However, the present invention is not limited in any way to the examples shown below.

[0035] (Examples 1-5 and Comparative Examples 1-2) The aforementioned composite nonwoven wiper is folded into four or six folds using a folding machine, as shown in Figures 5 and 6, resulting in a size of 168 mm x 170 mm in both the horizontal and vertical directions, with a basis weight of 60 g / m². 2 A roughly square-shaped wiper was formed. These 60 wipers were stored stacked inside the aforementioned storage box. Furthermore, the four-fold wiper is thinner and easier to remove than the six-fold wiper. The stacking orientation is as shown in A and B of Figures 5 and 6, (Stacking orientation A) The final folded edge faces the second opening. (Stacking orientation B) The final folded edge faces either the right or left side. Sample wiper storage cartons were manufactured with two different stacking orientations. For storage boxes, the thickness is 0.6 mm and the basis weight is 450 g / m². 2 Paperboard for packaging was used as the base material, and the shapes shown in Figures 1 to 3 were used. The storage box was formed as a roughly cubic box with overall dimensions of 170mm x 175mm x 170mm in width (X) x height (Y) x depth (Z).

[0036] As shown in Table 1, samples for Examples 1-5 and Comparative Examples 1-2 were obtained by varying the width and height of the first and second openings, respectively. In Table 1, the width ratio refers to the ratio (%) of the width of the first opening, the width of the second opening, and the width of the front surface, respectively. The opening area ratio refers to the ratio (%) of the area of ​​the first opening to the top surface area, or the ratio (%) of the area of ​​the second opening to the front surface area. For the second opening, the length (mm) from the bottom surface to the bottom edge of the second opening is indicated.

[0037] [Evaluation Method] For the samples of Examples 1-5 and Comparative Examples 1-2, the following tests were conducted with 10 monitors to evaluate the ease of gripping the sheets, the ease of removing the sheets (how easy it is for a person to remove the wipers from the storage box), the durability of the box (shape stability when pressure is applied by a pressure testing machine), and the dustproofness (dustproofness expected based on the size of the opening area). (Ease of picking up the sheet) The ease of picking up the first opening was evaluated based on how easily the center of the folded sheet could be picked up, while the ease of picking up the second opening was evaluated based on how easily one or three sheets could be picked up at once from the edges of the folded sheet. Ten monitors examined the ease of picking up the sheets, and each of them evaluated the ease of picking up a total of 50 sheets according to the following criteria. ◎: Excellent (9 or more people responded that it was easy to take out) ○: Good (6 to 8 people answered that it was easy to take out) △: Average (4 to 5 people answered that it was easy to take out) ×: Poor (3 or fewer respondents said it was easy to take out)

[0038] (Ease of removing sheets) The ease of removal from the first opening was evaluated based on how easy it was to remove one sheet at a time, while the ease of removal from the second opening was evaluated based on how easy it was to remove one sheet at a time and three sheets at once. Ten monitors investigated how easy it was to pick up the sheets, and each of them evaluated the ease of picking up a total of 50 sheets according to the following criteria. ◎: Excellent (9 or more people responded that it was easy to take out) ○: Good (6 to 8 people answered that it was easy to take out) △: Average (4 to 5 people answered that it was easy to take out) ×: Poor (3 or fewer respondents said it was easy to take out)

[0039] (Box durability) Five storage boxes without wipers were prepared, and a predetermined pressure was applied from the top side using a pressure testing machine to evaluate how easily the storage boxes deformed. ◎: Very difficult to deform ○: Difficult to deform △: Normal ×: Easily deformed (dustproof) The dustproof performance was evaluated based on the sum of the ratios of the opening areas of the first and second openings. Generally, the smaller the sum of the opening area ratios, the higher the dustproof performance. ◎: Excellent (Total is 100% or less) ○: Good (Total score between 101% and 120%) △: Normal (Total is 121-140%) ×: Bad (Total is 141% or higher)

[0040] [Table 1]

[0041] Table 1 shows that within the width and height range of the dispensing openings in Examples 1 to 5, there were no negative evaluations for the four evaluation items: ease of picking up the sheets, ease of removing the sheets, and durability of the box, indicating that a good and practical wiper storage carton can be provided. On the other hand, the wiper storage cartons in Comparative Examples 1 and 2 received poor evaluations in at least two of the four evaluation items, indicating that their performance was inferior to that of the example product.

[0042] Although the present invention has been described above with examples of embodiments, the technical scope of the present invention is not limited to the configurations described in the above embodiments. The technical scope of the present invention should be determined based on the description in the claims, and it goes without saying that various modifications, additions of configurations, or improvements can be made within that scope.
