Description

[Technical Field]

[0001] The present invention relates to a cleaning sheet storage container having an opening for pulling out the cleaning sheet. [Background technology]

[0002] Cleaning sheets, such as rolled wet wipes, are stored in a container with a dispensing opening. The dispensing opening is attached to the top of a cylindrical or rectangular container as a lid, and the cleaning sheets are pulled out through the dispensing opening. The cleaning sheets are perforated at regular intervals, and when pulled out through the dispensing opening, they are torn along the perforations and pulled out one sheet at a time. To facilitate separation along the perforations, proposed dispensing openings for cleaning sheets have been provided with circular or star-shaped through-holes or cross-shaped slits. However, these proposals have resulted in some cases where the cleaning sheets are torn along the perforations, others where the subsequent cleaning sheets are pulled out without being torn, or the sheets become clogged due to twisting, making them impossible to pull out. For this reason, Patent Document 1 proposes a dispensing opening angled relative to the axial direction of the container, allowing the sheets to pass through a round hole and rub against the inclined dispensing surface, making it easier to tear them along the perforations. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent 7021310

[0004] The cleaning sheet, which is processed into a roll with perforations at regular intervals, twists in the direction of the roll when pulled out through the opening. The twisting often causes the cleaning sheet to become tangled, and in that case, if there is only a round hole as proposed in Patent Document 1, the cleaning sheet will get stuck and will not come out.

[0005] This is because the only purpose of Patent Document 1 is to make the cleaning sheet easier to tear along the perforations.

[0006] In contrast to the conventional technology, the object of the present invention is to provide a container with a take-out opening that has perforations at regular intervals and that allows cleaning sheets, such as wet wipes, wound in a roll to be untangled and cut along the perforations when taking them out.

[0007] A cleaning sheet storage container for storing cleaning sheets, the container having an opening for pulling out the cleaning sheets in the axial direction of the container, the opening having a base surface and a slit formed in the base surface through which the sheets can be pulled out, the base surface having an angle between a normal to the base surface and the axial direction set in the range of 10° to 90°, and the slit extending in the same direction as the inclination direction of the base surface.

[0008] By using the container with the take-out port of the present invention, the cleaning sheet always passes through the slit in the axial direction of the container opened on the base surface, and the slit untangles the twisted and tangled cleaning sheet, eliminating the problem of the cleaning sheet being jammed and unable to be taken out.

[0009] In addition, the slits, which are opened in the same direction as the inclination of the base surface, generate large frictional resistance at their apexes, and the pulled-out cleaning sheet and the succeeding cleaning sheet are separated by the perforations immediately after the leading edge of the succeeding cleaning sheet passes through the slit.

[0011] An embodiment of the present invention will be described with reference to the drawings. Fig. 3 is a cross-sectional view of the outlet and a perspective view of the container according to one embodiment of the present invention. Cleaning sheets are used, for example, in medical institutions to wipe doorknobs, chairs, desks, etc., and a nonwoven fabric used in the chemical-impregnated cleaning sheets has been proposed that is a blend of pulp, cotton, and rayon and is easy to cut.

[0012] The chemicals used in the chemical-impregnated cleaning sheets are alcohol and invert soap, and the liquid deteriorates little even on nonwoven fabrics made from a blend of pulp, cotton, and rayon.

[0013] However, in medical settings, it is important to take measures against norovirus, which does not have an envelope, and it is essential to treat patient vomit with a 1000 ppm chlorine-based chemical (sodium hypochlorite), and the chemical used in chemical-impregnated cleaning sheets is required to be sodium hypochlorite.

[0014] When sodium hypochlorite is impregnated into nonwoven fabric made from a blend of pulp, cotton, and rayon, the effective chlorine concentration quickly decreases (decomposes), so the disinfecting performance cannot be maintained for a long period of time, and therefore there have been no disinfecting wet cleaning sheets that are pre-impregnated with the chemical solution.

[0015] In recent years, with the advancement of nonwoven fabric manufacturing technology, a disinfecting wet cleaning sheet impregnated with sodium hypochlorite has been developed and proposed, using a nonwoven fabric made solely of polyester.

[0016] However, cleaning sheets made solely of polyester are very strong and will not tear at the perforations even when pulled upwards through a conventional outlet.

[0017] To cut it, you are forced to pull it diagonally upwards from the side, rather than upwards.

[0018] Medical institutions that are busy caring for patients need cleaning sheets that can be used simply by "pulling them up" in the same way as normal, without being restricted by how they are taken out.

[0019] Therefore, by setting the outlet having a base surface on which the slits are formed at an angle relative to the axial direction of the container, the nonwoven fabric is guided into the slits one after another, and tension is applied simply by pulling it upward through the obliquely inclined slits, allowing the cleaning sheet to be cut along the perforations.

[0020] Furthermore, wet wipes are perforated at regular intervals and rolled into a roll. When pulled out from the top, they tend to become twisted and tangled from the center of the roll, but the slits untangle them, allowing them to be removed smoothly.

[0021] In medical institutions, sodium hypochlorite is required as the chemical solution used in the disinfectant wet cleaning sheets impregnated with the chemical solution used to wipe doorknobs, chairs, desks, etc.

[0022] As a result, in recent years, nonwoven fabric manufacturing technology has improved, and disinfecting wet cleaning sheets that use nonwoven fabric made only of polyester and are impregnated with sodium hypochlorite have been developed and proposed.However, there have been issues with them getting clogged and being difficult to remove, and the perforations make them difficult to tear.

[0023] The present invention reduces the workload at medical institutions that are busy caring for patients, without changing the normal method of removing the cleaning sheet by "pulling it up." This is particularly effective at medical institutions that use sodium hypochlorite by impregnating nonwoven fabrics on a daily basis.

[0024] We believe that this system will be rapidly adopted by medical institutions that want to secure as much time as possible for interacting with patients.

[0025] 1 and 2 are perspective views of the outlet 3. The entire cleaning sheet container comprises a container 5 and the outlet 3, which is a lid member that closes one end. Both the container 5 and the outlet 3, which is a lid member, are made of a resin material such as polyethylene or polypropylene. The container 5 is a substantially cylindrical container with a bottom, and one axial end is open. The outlet 3, which is a lid member, covers the opening at the end of the container 5 and prevents the cleaning sheets stored inside from drying out. As shown in FIG. 2, the cleaning sheet is drawn out through a slit 1 opened in the base surface 2. Here, the base surface 2 is a substantially circular surface provided in the center of the outlet 3, and the slit 1 is a strip-like through-hole provided in the base surface 2.

[0026] 3 is a perspective view of the container 5 and a cross-sectional view of the outlet 3. The axial direction 8 of the container 5 is indicated by an arrow. As shown in FIG. 4, the angle between the normal 10 of the base surface 2 and the axial direction 8 is set to be in the range of 10° to 90°.

[0027] A rolled cleaning sheet is pulled out from the center of the roll and always twisted into a spiral shape. Even in this case, if slit 1 is left open as shown in Figure 5, the frictional resistance of slit 1 will untwist the cleaning sheet and allow it to be pulled out. Also, the frictional resistance of slit 1 will cause the cleaning sheet to be cut regularly as shown in Figure 6.

[0028] However, the most important thing here is that the slits 1 are opened in the same direction 11 as the inclination of the base surface 2, as in Figure 7. For example, even in the case of slits opened in a straight or cross shape, if they are not opened in the same direction 11 as the inclination of the base surface 2, as in Figure 8, it will be difficult to pull out the cleaning sheet due to too much friction (in the case of a straight horizontal line) or the slits 1 getting caught where they cross (in the case of a tilted cross). By opening the slits 1 in the same direction 11 as the inclination of the base surface 2, as in Figure 7, the cleaning sheet can always be guided into the slit 1 and can be smoothly removed simply by "pulling up the cleaning sheet" in the usual way.

[0029] As shown in Figure 9, the slit 1 needs to be opened in the same direction 11 as the inclination direction of the base surface 2, and the shape of the slit 1 can be a straight line, a cross, a slit + round hole, a slit + square hole, or a slit + triangular hole. [Explanation of symbols]
