BEST MODE

[0035] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. Prior to the description, it should be understood that the terms used in the specification and the appended claims should not be construed as limited to general and dictionary meanings, but interpreted based on the meanings and concepts corresponding to technical aspects of the present disclosure on the basis of the principle that the inventor is allowed to define terms appropriately for the best explanation. Therefore, the description proposed herein is just a preferable example for the purpose of illustrations only, not intended to limit the scope of the disclosure, so it should be understood that other equivalents and modifications could be made thereto without departing from the scope of the disclosure.

[0036] FIG. 1 is a partially sectioned perspective view showing a wiper kit for cleaning according to an embodiment of the present disclosure, and FIG. 2 is a cross-sectioned view, taken along the line A-A of FIG. 1.

[0037] Referring to FIGS. 1 and 2, a wiper kit for cleaning according to an embodiment of the present disclosure includes an outer bag 100 accommodating a wiper 1, an inner bag 101 provided in an inner space of the outer bag 100 and hermetically containing a cleaning liquid 2 therein, and an opening member 103 connected to the inner bag 101 and extending toward an outlet 104 of the outer bag 100.

[0038] The outer bag 100 has an inner space for accommodating the wiper 1 and the inner bag 101. The outer bag 100 may be preferably formed using, for example, a flexible lamination resin made of polyethylene. Here, the wiper 1 is prepared by weaving or knitting a fiber material capable of cleaning internal facilities of a clean room, and a plurality of wipers 1 are stacked and disposed adjacent to the inner bag 101.

[0039] One edge of the outer bag 100 is configured to be capable of opening in order to take off the wiper 1 during a cleaning work. One edge of the outer bag 100 may be opened by cutting with scissors or the like. A zipper structure 102 composed of a protrusion and a groove as a pair along a width direction may be provided at the outlet 104 of the outer bag 100 so that only wipers 1 may be taken out as many as necessary during a cleaning work and then the rest wipers may be temporarily stored in a clean state.

[0040] The inner bag 101 is connected to one inner side of the outer bag 100, and the cleaning liquid 2 is enclosed therein. In order to connect and fix the inner bag 101 to the outer bag 100, a fixing ribbon 108 of a predetermined length may be added to the outer bag 100 so that the fixing ribbon 108 is interposed in one edge of the outer bag 100.

[0041] The inner bag 101 is formed using a resin sheet such as transparent vinyl. At this time, a peripheral edge of the resin sheet is sealed to one inner side of the outer bag 100 to form an inner space capable of accommodating the cleaning liquid 2. Here, the cleaning liquid 2 may employ a chemical cleaning agent such as ethanol, acetone, NMP, IPA, a mixture of ethanol and acetone mixture, or the like.

[0042] Among the peripheral edge of the inner bag 101, at least one side is more preferably sealed together with the outer bag 100 in a state where the side is interposed in the edge of the outer bag 100. In this configuration, the cleaning liquid is received in the inner bag 101 through the edge in a state where the other portions than the edge of the inner bag 101 is sealed, and after that, the outer bag 100 and the inner bag 101 are sealed simultaneously in a state where the edge is interposed in a portion of the edge of the outer bag 100. In this case, the number of processes may be reduced for sealing.

[0043] The opening member 103 may be integrally formed with a part of the resin sheet which constitutes the inner bag 101 or alternatively may be attached to a part of the resin sheet which constitutes the inner bag 101. The opening member 103 has a resin ribbon structure extending from the resin sheet constituting the inner bag 101 toward the outlet 104 of the outer bag 100. An end portion of the opening member 103 is preferably accommodated inside the outer bag 100 so as not to be exposed to the outside.

[0044] If the opening member 103 is pulled toward the outlet 104 of the outer bag 100 in a state where the outer bag 100 is opened, a part of the resin sheet of the inner bag 101 connected to the opening member 103 is torn so that the inner bag 101 is ruptured and opened.

[0045] As shown in FIG. 3, a cutoff line 107 is formed at the inner bag 101 so that the inner bag 101 may be ruptured easily and accurately. If the opening member 103 is pulled toward the top of the ground, the inner bag 101 is ruptured along the cutoff line 107. The opening member 103 is formed to be connected to at least a part of the cutoff line 107 to enable this action.

[0046] The cutoff line 107 may include a first cut portion 107a in which a pair of dotted lines are formed in parallel with a predetermined width (interval), and a second cut portion 107b connected to the first cut portion 107a and having a slope so that the width of the pair of dotted lines is gradually decreased. In this case, the opening member 103 is connected to the second cut portion 107b. According to this structure, the first cut portion 107a may have various widths due to the inclined pattern of the second cut portion 107b, and the cutoff line 107 may be precisely torn. Alternatively, the opening member 103 may also be connected substantially with the same width as the pair of dotted lines of the cutoff line 107 as shown in FIG. 4.

[0047] As shown in FIG. 5, the cutoff line 107 is formed to have at least one pair of dotted lines, and the pair of dotted lines may extend with a width gradually increasing from one edge of the inner bag 101 toward the other edge thereof. According to this structure, the cutoff line 107 may be smoothly torn off with a soft feeling and a sufficient rupture area may be secured.

[0048] FIG. 6 shows an operation example of the wiper kit for cleaning according to an embodiment of the present disclosure.

[0049] As shown in FIG. 6, if the opening member 103 is pulled, the cutoff line 107 of the inner bag 101 connected to the opening member 103 is torn so that the inner bag 101 is ruptured and opened, whereby the cleaning liquid 2 is discharged out of the inner bag 101. The discharged cleaning liquid 2 is absorbed into the wiper 1 accommodated in the outer bag 100.

[0050] Therefore, when cleaning facilities in a clean room, an operator may apply the cleaning liquid 2 to the wiper 1 quickly and safely by pulling the opening member 103 and then perform the cleaning work conveniently by opening the outer bag 100 and taking off the wiper 1.

[0051] FIG. 7 is a partially sectioned perspective view showing a wiper kit for cleaning according to another embodiment of the present disclosure, and FIG. 8 is a cross-sectioned view, taken along the line B-B of FIG. 7.

[0052] Referring to FIGS. 7 and 8, a wiper kit for cleaning according to another embodiment of the present disclosure includes an outer bag 100 accommodating a wiper 1, an inner bag 101 provided at an inner space of the outer bag 100 and hermetically containing a cleaning liquid 2 therein, an opening member 103 connected to the inner bag 101 and extending toward an outlet 104 of the outer bag 100, and a grip 106 connected to the opening member 103 as a part of the outer bag 100.

[0053] The outer bag 100 has an inner space for accommodating the wiper 1 and the inner bag 101. The outer bag 100 may be preferably formed using, for example, a flexible lamination resin made of polyethylene. Here, the wiper 1 is prepared by weaving or knitting a fiber material capable of cleaning internal facilities of a clean room, and a plurality of wipers 1 are stacked and disposed adjacent to the inner bag 101.

[0054] One edge of the outer bag 100 is configured to be capable of opening in order to take off the wiper 1 during a cleaning work. One edge of the outer bag 100 may be opened by cutting with scissors or the like. A zipper structure 102 composed of a protrusion and a groove as a pair along a width direction may be provided at the outlet 104 of the outer bag 100 so that only wipers 1 may be taken out as many as necessary during a cleaning work and then the rest wipers may be temporarily stored in a clean state.

[0055] The inner bag 101 is connected to one inner side of the outer bag 100, and the cleaning liquid 2 is enclosed therein.

[0056] The inner bag 101 is formed using, for example, a resin sheet such as transparent vinyl. At this time, a peripheral edge of the resin sheet constituting the inner bag 101 is sealed to one inner side of the outer bag 100 to form an inner space capable of accommodating the cleaning liquid 2. Here, the cleaning liquid 2 may employ a chemical cleaning agent such as ethanol, NMP, IPA, a mixture of ethanol and acetone mixture, acetone, or the like.

[0057] The opening member 103 may be integrally formed with a part of the resin sheet which constitutes the inner bag 101 or alternatively may be attached to a part of the resin sheet which constitutes the inner bag 101. The opening member 103 has a resin ribbon structure extending from the resin sheet constituting the inner bag 101 toward the outlet 104 of the outer bag 100. The opening member 103 is accommodated inside the outer bag 100 so as not to be exposed to the outside and is connected to the grip 106.

[0058] The grip 106 is a part of a folding portion 105 which is formed by folding an opposite edge of the outer bag 100, namely an end of the outer bag 100 opposite to the outlet, in a zigzag pattern in a thickness direction of the outer bag 100. The grip 106 is preferably located at a central point of the zigzag pattern of the folding portion 105 and is movable in a direction opposite to the outlet of the outer bag 100. The opening member 103 is connected to the inner surface of the grip 106 by sealing. Here, the grip 106 may be protruded relative to at least one folding portion adjacent thereto so as to be easily identified.

[0059] If a user pulls the grip 106, the opening member 103 connected thereto is pulled in a direction opposite to the outlet 104 of the outer bag 100.

[0060] Similar to the former embodiment, a cutoff line 107 (see FIG. 3) is formed at the inner bag 101 so that the inner bag 101 may be ruptured easily. If the opening member 103 is pulled, the inner bag 101 is ruptured along the cutoff line 107. The opening member 103 is formed to be connected to at least a part of the cutoff line 107 to enable this action.

[0061] The cutoff line 107 includes a first cut portion 107a in which a pair of dotted lines are formed in parallel with a predetermined width, and a second cut portion 107b connected to the first cut portion 107a and having a slope so that the width of the pair of dotted lines is gradually decreased. Here, the opening member 103 may be connected to the second cut portion 107b.

[0062] Thus, if a user pulls the grip 106 out of the outer bag 100, the opening member 103 connected thereto is pulled, and the cutoff line 107 connected to the opening member 103 is torn so that the inner bag 101 is ruptured and opened. According to this structure, the inner bag 101 may be opened by pulling the grip 106, which is a part of the outer bag 100, in a state where the outer bag 100 is sealed, and thus it is possible to prevent a safety accident of an operator, caused by the chemical agent.

[0063] FIG. 9 shows an operation example of a sealing-type wiper kit for cleaning having the above configuration.

[0064] As shown in FIG. 9, if the grip 106 is pulled, the grip 106 is slightly spread with respect to the folding portion 105, and the opening member 103 is pulled in conjunction with the grip 106, so that an intensive pressure is applied to the cutoff line 107 of the inner bag 101 connected to the opening member 103. Accordingly, a portion of the resin sheet corresponding to the cutoff line 107 connected to the opening member 103 is torn to rupture and open the inner bag 101, whereby the cleaning liquid 2 is discharged out of the inner bag 101. The discharged cleaning liquid 2 is absorbed into the wiper 1 accommodated in the outer bag 100.

[0065] Therefore, when cleaning facilities in a clean room, an operator may apply the cleaning liquid 2 to the wiper 1 quickly and safely by pulling a part of the outer bag 100 to pull the opening member 103 located in the outer bag 100 so that the inner bag 101 is ruptured and opened easily, and then perform the cleaning work conveniently by opening the outer bag 100 and taking off the wiper 1.

[0066] As shown in FIG. 10, the folding portion 105 and the grip 106 may also be disposed at one side of a flat portion which is spaced at a predetermined distance from the end of the outer bag 100. In this case, the opening member 103 may have as long length as necessary, compared to the case where the folding portion 105 and the grip 106 are disposed at the edge of the outer bag 100, without increasing the overall size of the product, and thus it is possible to make the rupture length of the inner bag 100 long enough. Considering this effect, it is advantageous that the folding portion 105 and the grip 106 are located in a region between the edge of the outer bag 100 and the longitudinal midpoint of the outer bag 100.

[0067] The grip 106 may be provided as a part of the folding portion 105, similar to the former embodiment, and a separate small sheet patch may be additionally attached thereto.

[0068] According to another embodiment of the present disclosure, there is provided a wiper kit for cleaning, wherein a pair of folding portions 105 and a pair of grips 106 are provided symmetrically at both edges of the outer bag 100. In this case, as shown in FIG. 11, if the both edges of the outer bag 100 are simultaneously pulled outwardly, the opening member 103 is pulled in both opposite directions so that the cutoff line 107 is torn and the inner bag 101 is ruptured. According to this structure, it is possible to ensure a sufficient rupture area while the opening length of the opening member 103 is relatively shortened.

[0069] As described above, in the wiper kit for cleaning according to the present disclosure, since the cutoff line 107 is torn when the opening member 103 is pulled, the inner bag 101 may be ruptured easily and accurately, and also it is possible to prevent the opening member 103 from being damaged.

[0070] The present disclosure has been described in detail. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the disclosure, are given by way of illustration only, since various changes and modifications within the scope of the disclosure will become apparent to those skilled in the art from this detailed description.
