Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a wet tissue package. 
       BACKGROUND ART 
       [0002]    A wet tissue has been widely used for various purposes of wiping a body and the like. The wet tissue is formed as a web sheet that is formed by impregnating a chemical solution and the like into a ground fabric, and is generally accommodated in a sealed accommodation container so that the ground fabric may be maintained in a wet state by the chemical solution and the like. As the accommodation container, a cylindrical bottle type container has been widely used from the past (for example, see Patent Literatures 1 and 2). 
         [0003]    As illustrated in  FIG. 15 , a wet tissue accommodation body  201  disclosed in Patent Literature 1 includes a roll-shaped wet tissue  202  into which a chemical solution and the like are impregnated and a bottle type accommodation container  203  which accommodates the wet tissue  202 . The roll-shaped wet tissue  202  is formed by winding a thin-stripe-shaped elongated web sheet, the web sheet is provided with a perforation line  204  of which the extension direction follows the width direction of the web sheet. Further, a plurality of the perforation lines  204  are formed at a predetermined interval in the longitudinal direction of the web sheet. The accommodation container  203  is formed so that a container lid  206  is detachably provided in an upper portion of a container body  205 , and may accommodate the roll-shaped wet tissue  202  therein. A small hole  207  having a substantially circular shape is formed at the center of the container lid  206 , and the wet tissue  202  is drawn out from the small hole  207 . The small hole  207  is formed in a size in which a resistance force capable of separating the drawn wet tissue  202  by the perforation lines  204  is applied to the drawn wet tissue  202  when the front end of the roll-shaped wet tissue  202  is drawn out from the inside of the accommodation container  203 . Further, the container lid  206  is provided with an openable/closable cover  208  that seals the inside of the accommodation container  203 . 
         [0004]    Further, a wet tissue accommodation container disclosed in Patent Literature 2 is formed so as to accommodate a roll-shaped wet tissue therein, and an upper cover is attached to the upper portion thereof. The upper surface of the upper cover is provided with an extraction hole through which the wound end of the roll-shaped wet tissue is plucked out, a cutting and separating hole which separates the extracted wet tissue, and a connection hole which connects the extraction hole to the cutting and separating hole and guides the wet tissue extracted from the extraction hole to the cutting and separating hole.

       SUMMARY OF INVENTION 
     Technical Problem 
       [0007]    A wet tissue package disclosed in Patent Literature 1 may apply a resistance force capable of separating the wet tissue by the perforation lines to the wet tissue by decreasing the hole diameter of the small hole. For this reason, a problem arises in that the front end of the roll-shaped wet tissue may not easily pass through the small hole and the front end of the wet tissue may not be easily extracted to the outside. Further, in the case of the wet tissue package disclosed in Patent Literature 1, the wet tissue is extracted to the outside while being squeezed and wrinkled by the small hole due to the passage through the small hole. For this reason, a user needs to inevitably stretch the squeezed wet tissue whenever extracting the wet tissue. Accordingly, it takes more time in the work in which the user extracts the wet tissue for the wiping purpose, and hence a problem arises in that the workability is very poor. 
         [0008]    Even in the accommodation container disclosed in Patent Literature 2, the hole diameter of the cutting and separating hole is formed in a small size so that the resistance force capable of separating the wet tissue by the perforation lines may be applied to the wet tissue, and the drawn wet tissue is extracted to the outside while being wrinkled. For this reason, the user needs to stretch the squeezed wet tissue whenever extracting the wet tissue. Accordingly, it takes more time in the work in which the user extracts the wet tissue for the wiping purpose, and hence the workability is very poor. Further, in the accommodation container disclosed in Patent Literature 2, the extraction hole used to extract the wet tissue is formed separately from the cutting and separating hole used to separate the wet tissue, and the wet tissue accommodated in the accommodation container is formed in a roll shape. Accordingly, the user needs to perform a series of work in which the wet tissue is extracted from the extraction hole, the wet tissue is moved from the extraction hole to the cutting and separating hole, and the wet tissue is extracted to the outside from the cutting and separating hole. As a result, a problem arises in that the work becomes more complicated due to the additional work. 
         [0009]    Further, since the roll-shaped wet tissue is generally accommodated vertically in the accommodation container of the bottle type wet tissue package, the accommodation container is inevitably formed in the vertical long shape, and hence a problem arises in that the bottle type wet tissue package may not be easily decreased in size. Further, in the bottle type wet tissue package, the accommodation container increases in size, and hence a problem arises in that the manufacturing cost increases. 
         [0010]    The present invention is made in view of such problems, and an object thereof is to provide a compact wet tissue package that causes a user to easily extract a wet tissue from an accommodation container and reduces the manufacturing cost thereof. 
       Solution to Problem 
       [0011]    The present invention may be summarized as below.

         [0015]    (4) The wet tissue package according to (3), wherein the base plate includes an extraction hole forming member and a base plate body provided with an attachment portion forming an extraction hole forming portion by attaching the extraction hole forming member thereto, wherein the extraction hole forming member is provided with a hole portion that is attached to the attachment portion, and wherein the attachment portion is provided with a boss that is press-insertable into the hole portion. 
         [0016]    (5) The wet tissue package according to (3), wherein the base plate includes an extraction hole forming member and a base plate body provided with an attachment portion forming an extraction hole forming portion by attaching the extraction hole forming member thereto, wherein the extraction hole forming portion is provided with a rib that protrudes outward from the outer periphery of the extraction hole forming portion, and wherein the attachment portion is provided with a locking hole to which the rib is lockable. 
         [0017]    (6) The wet tissue package according to (3), wherein the base plate includes an extraction hole forming member, a base plate body provided with an attachment portion forming an extraction hole forming portion by attaching the extraction hole forming member thereto, and a fixing member that attaches and fixes the extraction hole forming portion to the attachment portion, wherein the fixing member is provided with a fixing hole through which a boss is insertable and a protrusion portion is formed so as to protrude outward from the outer periphery of the fixing member, and wherein the attachment portion is provided with a locking hole to which the protrusion portion is lockable. 
       Advantageous Effects of Invention 
       [0018]    According to the present invention, it is possible to obtain the wet tissue package in which the user may easily pluck the front end of the wet tissue when plucking out the wet tissue. Further, when the wet tissue that is drawn out from the plucking hole is raised upward, the drawing position moves from the plucking hole to the extraction hole. Accordingly, it is possible to reduce the effort or the complicatedness in operation in which the user moves the position of drawing the wet tissue from the plucking hole to the extraction hole.

     DESCRIPTION OF EMBODIMENTS 
     First Embodiment 
       [0034]    A first embodiment of a wet tissue package according to the present invention will be described with reference to  FIGS. 1 to 5 .  FIG. 1  is an external perspective view illustrating the external configuration of a wet tissue package according to a first embodiment of the present invention, where  FIG. 1A  is a view illustrating a state where a lid is closed and  FIG. 1B  illustrates a state where the lid is opened.

FIG. 5  is a front view illustrating the configuration of the base plate. Furthermore, it is assumed that the up-down direction (i.e. the vertical direction), the front-back direction (i.e. the forward and backward direction), and the left-right direction in the present specification respectively indicate the up-down direction, the front-back direction, and the left-right direction illustrated in  FIG. 1 . Further, it is assumed that the “front end of the wet tissue” of the present specification indicates the end close to the extraction hole formed in the base plate in the folded wet tissue body accommodated in the accommodation container. Furthermore, in the present specification, an example will be described in which a bag body is used as one kind of the accommodation container, but any member other than the bag body may be used as the accommodation container. 
         [0035]    &lt;Wet Tissue Package  1 &gt; 
         [0036]    As illustrated in  FIGS. 1 and 2 , a wet tissue package  1  according to this embodiment has a structure in which a folded wet tissue body  2  is accommodated in a bag body  3 . 
         [0037]    (Folded Wet Tissue Body  2 ) 
         [0038]    The folded wet tissue body  2  is obtained by impregnating a chemical solution and the like into a ground fabric such as a web sheet. The folded wet tissue body  2  has a structure in which the web sheet is folded. In a state where the folded web sheet is unfolded, that is, the web sheet is not folded, the web sheet has a structure in which a plurality of small web sheet pieces are continued. For example, the web sheet may have a sheet structure in which small web sheet pieces are continuously continued. Further, the web sheet may have a sheet structure in which a plurality of small web sheet pieces are arranged in series in facial order while partially overlapping one another. In the folded wet tissue body  2 , a plurality of turnback portions are formed by turning the web sheet forming the wet tissue back. As illustrated in  FIG. 2 , a first turnback portion  5  and a second turnback portion  6  are formed as the turnback portions. A plurality of planned portions  4  (i.e. a plurality of planned disjoining portions  4 ) to disjoin the folded wet tissue body  2  as a plurality of planned portions  40  (i.e. a plurality of planned separation portions  40 ) to separation the folded wet tissue body  2  are formed in the folded wet tissue body  2  at intervals, and in the example of  FIG. 3 , a plurality of planned portions to disjoin the folded wet tissue body  2  are formed repeatedly at a predetermined interval. 
         [0039]    Furthermore, in the present specification, a wet tissue  2   a  indicates a wet tissue that is separated from the folded wet tissue body  2  at the planned portion  40  to separate the folded wet tissue body  2 . Furthermore, the wet tissue  2   a  of the present specification indicates a sheet-like small web sheet piece that is separated from the folded wet tissue body  2 , but may indicate a web sheet that is not separated from the folded wet tissue body  2  yet. 
         [0040]    (Planned Portions  40  to Separation the Folded Wet Tissue Body) 
         [0041]    The planned portion  40  to separation the folded wet tissue body indicates a portion that is planned as a separation portion between the folded wet tissue body and the wet tissue when the wet tissue  2   a  is taken out from the folded wet tissue body  2 . The planned portion  40  to separation the folded wet tissue body is formed so that the wet tissue  2   a  may be separated, and is formed in the web sheet forming the folded wet tissue body  2 . In the example of  FIG. 3 , the planned portion  4  to disjoin the folded wet tissue body as the planned portion  40  to separation the folded wet tissue body is formed in the folded wet tissue body  2 . The planned portion  4  to disjoin the folded wet tissue body is formed so that the planned portion to disjoin the folded wet tissue body may be separated by the drawing tensile force applied to the wet tissue  2   a  when the wet tissue  2   a  is drawn out. As illustrated in  FIG. 3A , the planned portion  4  to disjoin the folded wet tissue body is provided with a plurality of spaces  4   a  that are formed at the same interval in the width direction of the folded wet tissue body  2 , and a connection portion  4   b  is formed between the spaces  4   a  so as to connect the folded wet tissue bodies  2 . In this embodiment, the connection portion  4   b  is formed at three positions in the width direction of the folded wet tissue body  2 , but the number or the shape of the connection portion  4   b  is not limited thereto. Further, the planned portion  4  to disjoin the folded wet tissue body may be formed so that the planned portion to disjoin the folded wet tissue body may be separated when a drawing tensile force is applied thereto. For example, the planned portion to disjoin the folded wet tissue body may be formed in a perforation line shape by shortening the gap between the space  4   a  and the connection portion  4   b  or may be formed in another shape. In such a case, in the state of the folded wet tissue body  2 , the wet tissues  2   a  are continuously connected by the planned portion  4  to disjoin the folded wet tissue body, and hence are formed in an elongated web shape as a whole. 
         [0042]      FIG. 3B  is an explanatory view illustrating a position where the planned portion  4  to disjoin the folded wet tissue body  2  is located at the elongated web sheet forming the folded wet tissue body  2 . In this drawing, the black circle indicates the position of the planned portion  4  to disjoin the folded wet tissue body  2 . As illustrated in  FIG. 3B , when the portion interposed between the first turnback portion  5  and the second turnback portion  6  adjacent to each other along the web surface of the elongated web sheet in the folded wet tissue body  2  is viewed, the planned portion  4  to disjoin the folded wet tissue body  2  is located at the center portion between the first turnback portion  5  and the second turnback portion  6 . Furthermore, as the vertical relation, the portion interposed between the first turnback portion  5  and the second turnback portion  6  adjacent to each other is formed by alternating a portion with the planned portion  4  to disjoin the folded wet tissue body  2  and a portion without the planned portion  4  to disjoin the folded wet tissue body  2 . 
         [0043]    Furthermore, the configuration of the folded wet tissue body  2  is not limited to the above-described configuration, and may be formed in any shape as long as the folded wet tissue body may be accommodated in the bag body  3 . For example, in this embodiment, the position of the planned portion  4  to disjoin the folded wet tissue body  2  is located at the center portion between the first turnback portion  5  and the second turnback portion  6 . However, the planned portion  4  to disjoin the folded wet tissue body  2  may be disposed at a position other than the center portion. Further, the planned portion  4  to disjoin the folded wet tissue body  2  may be disposed at a position where the first turnback portion  5  or the second turnback portion  6  is formed. Further, in this embodiment, as for the vertical relation of the folded wet tissue body  2 , the portion interposed between the first turnback portion  5  and the second turnback portion  6  is formed by alternating the portion with the planned portion  4  to disjoin the folded wet tissue body  2  and the portion without the planned portion  4  to disjoin the folded wet tissue body  2 , but may folded so that the portions with the planned portion  4  to disjoin the folded wet tissue body  2  overlap each other in the vertical direction. Further, the planned portion  4  to disjoin the folded wet tissue body  2  may be located at both positions where the first turnback portion  5  and the second turnback portion  6  are formed. 
         [0044]    Furthermore, various existing materials may be used as the base material for the folded wet tissue body  2 . Further, various existing chemical solutions and the like may be used as the chemical solution that is impregnated into the base material of the folded wet tissue body  2  of this embodiment. 
         [0045]    (Another Example of Folded Wet Tissue Body) 
         [0046]    The folded wet tissue body that is accommodated in the wet tissue package  1  is not limited to the folded wet tissue body  2  including the above-described planned portion  40 . For example, the wet tissue package  1  may accommodate the following folded wet tissue body instead of the folded wet tissue body  2 . 
         [0047]    That is, the wet tissue package  1  may accommodate a folded wet tissue body having a folded structure in which the separate wet tissues  2   a  are folded in a predetermined folding pattern while partially overlapping one another instead of the folded wet tissue body  2 . Such a folded wet tissue body is formed in a web sheet folded structure in which wet tissue folded in a predetermined pattern is used as the small web sheet pieces and the small web sheet pieces are piled while the ends of the separate small web sheet pieces overlap one another.  FIG. 4  is a schematic view illustrating an example of the folded wet tissue body.  FIG. 4A  illustrates the configuration of a folded wet tissue body  151  that has a folded structure formed by a Z-shaped folding method as so called, and  FIG. 4B  illustrates the configuration of a folded wet tissue body  155  that has a folded structure formed by a WZ-shaped folding method as so called. Furthermore, the folded structure of the folded wet tissue body may be a folded structure in which the next wet tissue is sequentially raised so as to pop up when the current wet tissue is raised. The folded structure of the folded wet tissue body may be a folded structure in which the folded wet tissue body is folded in a W-shape other than the Z-shape or the WZ-shape. The folded structure of the folded wet tissue body may be a folded structure in which the folded wet tissue body is folded in a shape other than the W-shape, the Z-shape or the WZ-shape. 
         [0048]    As illustrated in  FIG. 4A , the folded wet tissue body  151  having a Z-shaped folded structure is formed by piling a plurality of wet tissues folded in a Z-shape. Further, the folded wet tissue body  151  is formed by sequentially piling a plurality of wet tissues while forming the overlap portion  41  in which an upper surface of a termination end  152   a  of a wet tissue  152  overlaps a lower surface of a start end  153   a  of a next wet tissue  153 . When the wet tissue  152  is drawn out from the folded wet tissue body  151 , an acting force is exerted on the wet tissue  153  so that the termination end  152   a  of the wet tissue  152  raises the start end  153   a  of the next wet tissue  153  in the overlap portion  41 . Then, when the start end  153   a  of the next wet tissue  153  is drawn out to the outside of the bag body from an extraction hole (not illustrated), the termination end  152   a  of the wet tissue  152  is separated from the start end  153   a  of the next wet tissue  153 . At this time, the wet tissue is separated from the folded wet tissue body  151  at the overlap portion  41 . That is, in such a folded wet tissue body  151 , the overlap portion  41  is formed as planned portion  40  to separation the folded wet tissue body. 
         [0049]    As illustrated in  FIG. 4B , the folded wet tissue body  155  that is folded in a WZ-shape is formed by alternately piling a wet tissue  156  folded in a Z-shape and a wet tissue  157  folded in a W-shape. Here, the wet tissue  156  folded in a Z-shape and the wet tissue  157  folded in a W-shape form an overlap portion  42  by overlapping the start end of one wet tissue and the termination end of the other wet tissue. In the case of  FIG. 3B , the wet tissues are piled so that an upper surface of a termination end  156   a  of the wet tissue  156  folded in a Z-shape overlaps a lower surface of a start end  157   a  of the next wet tissue  157  folded in a W-shape. When the wet tissue  156  folded in a Z-shape is drawn out, an acting force is exerted on the wet tissue  157  so that the termination end  156   a  of the wet tissue  156  raises the start end  157   a  of the next wet tissue  157  folded in a W-shape at the overlap portion  42 . Then, when the start end  157   a  of the wet tissue  157  folded in a W-shape is drawn out to the outside of the bag body from an extraction hole (not illustrated), the termination end  156   a  of the wet tissue  156  folded in a Z-shape is separated from the start end  157   a  of the next wet tissue  157  folded in a W-shape. Furthermore, the wet tissue is raised by the same action even when the start end  158   a  of the wet tissue  158  folded in a Z-shape is drawn out after the wet tissue  157  folded in a W-shape is drawn out. At this time, the wet tissue is separated from the folded wet tissue body  151  at the overlap portion  42 . That is, as the folded wet tissue body  151  having a Z-shaped folded structure, even the folded wet tissue body  155  folded in a WZ-shape is provided with the overlap portion  42  as the planned portion  40  to separation the folded wet tissue body 
         [0050]    (Bag Body  3 ) 
         [0051]    The bag body  3  is included in the concept of an accommodation container  160  that accommodates the folded wet tissue body  2  therein. As illustrated in  FIG. 1 , the bag body  3  is formed by bonding a base plate  10  to the main bag body  3   a . For example, the main bag body  3   a  is formed in a pillow-like bag shape by a sheet material such as a plastic film having air-tightness and flexibility. Further, the bag body  3  is formed so that both front and rear ends of the main bag body  3   a  are air-tightly sealed by heat-seal. 
         [0052]    In the example illustrated in  FIG. 2 , the sheet material that forms the main bag body  3   a  of the bag body  3  is formed in a double-layer structure with an inner layer  7  and an outer layer  8 . The material that is used in the inner layer  7  and the outer layer  8  may be appropriately selected. Specifically, in the inner layer  7 , for example, a film formed of plastic such as polyethylene, polypropylene, polyester, polyamide, vinyl chloride, vinylidene chloride, and cellophane, a laminate film formed of two or more of these materials, a single film, or a complex film formed by laminating an aluminum foil on a laminate film may be used. In the outer layer  8 , for example, a polyethylene terephthalate (PET) film may be used. Furthermore, the case where the main bag body  3   a  of the bag body  3  is formed by two layers, that is, the inner layer  7  and the outer layer  8  like this embodiment is an example of the bag body  3 . Further, the structure of the sheet material that forms the main bag body  3   a  of the bag body  3  is not limited thereto, and may be formed as a multi-layer structure having three or more layers or a single-layer structure. 
         [0053]    As illustrated in  FIGS. 1 and 2 , the main bag body  3   a  is provided with an opening  9 . The opening  9  is formed in a size in which the base plate  10  to be described later is attachable to the opening. 
         [0054]    (Base Plate  10 ) 
         [0055]    The base plate  10  is attached to the position of the opening  9  of the main bag body  3   a . It is desirable that the base plate  10  be placed on the inner surface of the main bag body  3   a  and be attached to the inner surface of the bag body  3  by hot-melt or the like in that the outer peripheral end surface of the base plate  10  may not be exposed. The base plate  10  is disposed so that an extraction hole  13  and a notch portion  43  face the opening  9 . The material of the base plate  10  may be appropriately selected, but a plate-shaped member that is formed of a thermoplastic resin material such as polyethylene and polypropylene is desirably selected. As illustrated in  FIGS. 2 and 5 , the base plate  10  includes a concave portion  11  that is formed at the center thereof, the extraction hole  13  is opened to the bottom portion of the concave portion  11 , and the notch portion  43  is formed at a predetermined position of the base plate  10 . Furthermore, the reference numeral  14  of  FIG. 5  indicates an area that forms an adhesion portion that is used when the base plate  10  adheres to the inner surface of the bag body  3  by heat-seal. 
         [0056]    (Notch Portion  43 ) 
         [0057]    The notch portion  43  may be formed in an appropriate shape such as a U-shape, a mountain shape, and a tongue shape in the top view of the base plate  10 . A shape of the notch portion  43  is shown in the embodiment of  FIGS. 1  and  5 , which is notched from a predetermined position of the outer peripheral edge of the base plate  10  toward the extraction hole  13  of the concave portion  11  as one example. And the notch portion  43  forms a recessed portion  44  in the outer peripheral edge of the base plate  10  in the top view of the base plate  10 . The notch portion  43  forms a part of the plucking hole  12  while the base plate  10  is attached to the bag body  3 . The size of the notch portion  43  may be appropriately set, but it ensures the size in which the plucking hole  12  may be formed while the base plate is attached to the bag body  3 . Further, the shape of the notch portion  43  may be formed in a shape in which the plucking hole  12  may be formed in a sufficient size while the base plate  10  is attached to the bag body  3 . 
         [0058]    Further, the notch portion  43  is provided with a notch extension portion  43   a . The notch extension portion  43   a  is a portion that extends toward the extraction hole  13  and communicates with the extraction hole  13 . Then, the notch extension portion  43   a  of the notch portion  43  is a portion which is sequentially tapered as it goes toward the extraction hole  13 . The notch extension portion  43   a  is a portion that forms an extension portion  12   a  of the plucking hole  12  while the base plate  10  is attached to the bag body  3 . Such a notch extension portion  43   a  may be formed by notching a predetermined portion inside the notch portion  43  in a tapered shape toward the extraction hole  13 . 
         [0059]    (Plucking Hole  12 ) 
         [0060]    The plucking hole  12  is a hole through which the wet tissue  2   a  is plucked outward. As illustrated in  FIG. 1 , the plucking hole  12  is formed by the notch portion  43  and a part of the edge of the opening  9  by attaching the base plate  10  to the position of the opening  9  of the bag body  3 . More specifically, the plucking hole  12  is formed in a portion that is surrounded by a portion exposed to the outside from the opening  9  in the portion along the peripheral edge of the notch portion  43  and a portion intersecting the notch portion  43  of the base plate  10  in the edge of the opening  9  while the lid  17  is separated from the wet tissue package  1  in the top view of the wet tissue package  1 . Further, the plucking hole  12  is formed as a portion opened in a size in which the wet tissue  2   a  accommodated in the bag body  3  may be plucked. Furthermore, the top view of the wet tissue package  1  indicates the case where the wet tissue package  1  is viewed from the upside thereof in  FIG. 1A  or  2 . 
         [0061]    In the wet tissue package  1  of the present invention, there is a concern that the wet tissue may not be plucked from the plucking hole  12  by a comparatively thick finger of a user when the user tries to pluck the wet tissue. However, since a part of the plucking hole  12  is formed by the bag body  3  as described above, the wet tissue may be appropriately and easily plucked from the plucking hole  12  due to the flexibility of the bag body  3  even when the user has a comparatively thick finger, and hence the above-described concern may be prevented. 
         [0062]    (Extraction Hole  13 ) 
         [0063]    The extraction hole  13  may be set in an appropriate size as long as a function is ensured in which the wet tissue may be separated from the folded wet tissue body  2  by the planned separation portion  40 . More specifically, the extraction hole  13  is formed so as to apply a friction resistance to the plucked wet tissue  2   a  while communicating with the notch portion  43 , that is, the extension portion  12   a  of the plucking hole  12 . 
         [0064]    In the example of  FIG. 1 , the extraction hole  13  is formed in a shape in which two circles partially overlap each other, and a projection portion  15  is formed in a portion that is formed by the overlap of two circles so as to protrude toward the inside of the extraction hole  13 . The projection portion  15  is formed so as to be in contact with the inner end of the notch extension portion  43   a . In this embodiment, the projection portion  15  includes two protrusion portions  15   a  and  15   b , and becomes closer to the position between the protrusion portions  15   a  and  15   b  as it goes toward the inner end of the notch extension portion  43 . In the projection portion  15 , it is possible to suppress the folded wet tissue body  2  that is drawn out from the inside of the extraction hole  13  from moving to the plucking hole  12  as the projection degree of the projection portion  15  increases. Accordingly, the friction resistance applied to the plucked folded wet tissue body  2  increases. 
         [0065]    Further, the extraction hole  13  is provided with a protrusion  16  that is provided at a position facing the projection portion  15  so as to protrude toward the inside of the extraction hole  13 . The protrusion  16  is used to increase the friction resistance applied to the plucked folded wet tissue body  2 . Furthermore, the reference numeral  13   a  of  FIG. 5  indicates a slit that is formed so as to extend from the extraction hole  13  in the front-back direction. 
         [0066]    Furthermore, the shape and the size of the projection portion  15  are not limited as long as the friction resistance applied to the folded wet tissue body  2  may be increased and the movement of the plucked folded wet tissue body  2  from the inside of the extraction hole  13  to the plucking hole  12  may be prevented. Further, the shape and the size of the protrusion  16  are not limited as long as the friction resistance applied to the folded wet tissue body  2  may be increased. 
         [0067]    In this way, in the wet tissue package  1 , the extraction hole  13  is provided with the projection portion  15  and the protrusion  16 , and the projection portion  15  and the protrusion  16  may be disposed so that the gap between the projection portion  15  and the protrusion  16  partially narrows the extraction hole  13 . In this case, even when the hole diameter of the extraction hole  13  is not set to a small size beyond necessity, an appropriate resistance force may be applied to the wet tissue  2   a  when the wet tissue  2   a  is drawn out from the extraction hole  13 . For this reason, the drawn wet tissue  2   a  is not squeezed and wrinkled, and hence the user may draw the wet tissue while maintaining the convenience in use. Accordingly, according to the wet tissue package  1  of this embodiment, it is possible to reduce the effort of the user in use, and hence largely prevent the complicatedness in use. 
         [0068]    (Lid  17 ) 
         [0069]    As illustrated in  FIGS. 1 and 2 , the upper surface of the bag body  3  is provided with the lid  17 . The lid  17  is provided in an openable and closeable manner so as to seal the plucking hole  12  and the extraction hole  13  of the wet tissue package  1 . For example, the lid is provided in the upper surface of the bag body  3  by hot-melt or the like. In the lid  17 , a flexible film or a sheet-like flap is suitably used. An adhesive layer (not illustrated) is formed on the lower surface of the lid  17 , and seals the inside of the bag body  3  when the adhesive layer adheres to the upper surface of the bag body  3 . As the adhesive layer, for example, a pressure-sensitive adhesive may be exemplified which mainly includes acrylic adhesive paste, flexible polyvinyl chloride composition, and graftmer such as graft copolymer in which vinyl chloride monomer is graft-polymerized with ethylene-vinyl acetate copolymer, but the present invention is not limited thereto. In this embodiment, as illustrated in  FIG. 1 , the lid  17  is formed in a substantially rectangular shape having a forward plucking portion, but the shape is not limited as long as the plucking hole  12  and the extraction hole  13  may be sealed. 
         [0070]    In the wet tissue package  1 , the lid  17  is appropriately stuck to the upper surface of the bag body  3  or is partially peeled off therefrom in response to the operation of drawing out the sheet-like wet tissue  2   a . When the lid  17  is stuck to the upper surface of the bag body  3 , the inside of the bag body  3  may be air-tightly sealed by the adhesive layer, and hence the chemical solution and the like impregnated into the folded wet tissue body  2  does not evaporate. Furthermore, a portion that pops out from the extraction hole  13  in the wet tissue  2   a  is accommodated in the concave portion  11  formed in the base plate  10  when the lid  17  is stuck to the upper surface of the bag body  3 . For this reason, it is possible to prevent a concern that the chemical solution and the like may evaporate from the portion that pops out from the extraction hole  13  in the wet tissue  2   a.    
         [0071]    Since the wet tissue package  1  of this embodiment is formed so that the folded wet tissue body  2  formed by folding the wet tissue  2   a  is accommodated in the bag body  3 , the entire wet tissue package  1  may be decreased in size, and the manufacturing cost may be largely reduced. 
         [0072]    Further, since the wet tissue package  1  is formed so that the folded wet tissue body  2  is accommodated in the accommodation container as the bag body  3 , it is possible to suppress a concern that the wet tissue  2   a  is largely twisted when the front end of the wet tissue  2   a  is drawn out. For this reason, according to the wet tissue package  1 , it is possible to reduce a concern that the drawn wet tissue  2   a  is largely wrinkled. 
         [0073]    Moreover, in the wet tissue package  1  according to the present invention, a state in which the front end (which is also the front end of the wet tissue) of the folded wet tissue body  2  accommodated in the accommodation container pops out from the extraction hole toward the outside of the accommodation container is maintained after the wet tissue is raised and is separated by the planned separation portion  40 . For this reason, it is possible to efficiently perform the operation in which the user draws out the next wet tissue, and hence to solve the complicatedness in which the front end of the wet tissue is plucked and drawn out from the inside of the accommodation container in each case. 
         [0074]    In the wet tissue package according to the present invention, the base plate that is attached to the main bag body is not limited to the above-described configuration, and may be also a base plate to be described in the following second embodiment. That is, another type in which a member forming an extraction hole forming portion to be described later is attached to an attachment hole of a base plate body so as to form a base plate may be employed other than the above-described type in which the extraction hole forming portion is formed in the base plate. 
       Second Embodiment 
       [0075]    A base plate  25  that is attached to a wet tissue package of a second embodiment will be described with reference to  FIGS. 6 and 7 . In a wet tissue package  21  of the second embodiment, the description of the same components as those of the wet tissue package  1  of the above-described first embodiment will not be repeated, and the same reference numerals will be used. 
         [0076]    The wet tissue package  21  is formed so that a folded wet tissue body  22  is accommodated in a bag body  23  as an accommodation container. 
         [0077]    As the folded wet tissue body  22 , the folded wet tissue body  2  having the structure illustrated in  FIG. 3B  may be used, but the present invention is not limited thereto. In addition, as the folded wet tissue body  22 , the folded wet tissue bodies  151  and  155  including the overlap portions  41  and  42  as the planned separation portion  40  may be used as illustrated in  FIGS. 4A and 4B . 
         [0078]    As illustrated in  FIG. 6 , the bag body  23  is formed by bonding the base plate  25  to a main bag body  23   a . The main bag body  23   a  is provided with an opening  24 , and the base plate  25  is attached to the opening  24  by an appropriate bonding method using hot-melt or the like. 
         [0079]    The base plate  25  is formed in a manner such that an extraction hole forming member  32  is attached to the base plate body  25   a  and the portion provided with the extraction hole forming member is the extraction hole forming portion. The base plate body  25   a  is a member that is formed of a thermoplastic resin material such as polyethylene and polypropylene by appropriately using an existing known method. The base plate body  25   a  is provided with a bottom surface  29   a  and a side wall portion  29   b  so that a concave portion  26  is formed at the center, where the side wall portion  29   b  is formed upright from the peripheral edge of the bottom surface  29   a  toward upward. Further, the concave portion  26  is provided with an attachment hole  28 , and the notch portion  43  is formed at a predetermined position of the outer peripheral edge of the base plate body  25   a  corresponding to a predetermined position of the outer peripheral edge of the base plate  25  so as to face the center. Furthermore, a planar portion that is formed at the outside of the concave portion  26  and is indicated by the reference numeral  31  is an adhesion surface which is formed by attaching the base plate  25  to the bag body  23  by an appropriate method using hot-melt or the like. 
         [0080]    The notch portion  43  is formed in a shape that is notched from a predetermined portion of the outer peripheral edge of the base plate body  25   a  toward the attachment hole  28 , and forms the recessed portion  44  in the outer peripheral edge of the base plate  25  in the top view of the base plate  25 . Further, as the notch portion  43  of the first embodiment, the notch portion  43  forms a part of a plucking hole  27  while the base plate  25  is attached to the bag body  3 . As in the first embodiment, the notch portion  43  includes the notch extension portion  43   a , and the notch extension portion  43   a  forms an extension portion  27   a  of the plucking hole  27  while the base plate  25  is attached to the bag body  23 . Even in the second embodiment, the notch extension portion  43   a  of the notch portion  43  is formed in a shape that is sequentially tapered as it goes toward the attachment hole  28  as in the first embodiment. 
         [0081]    Here, the plucking hole  27  is a hole through which the wet tissue  22   a  is plucked outward as in the plucking hole  12  described in the first embodiment. Further, the plucking hole  27  is formed by the notch portion  43  and a part of the edge of the opening  24  while the base plate  25  is attached to the bag body  23 . More specifically, the plucking hole  27  is formed in the portion that is surrounded by a portion exposed to the outside from the opening  24  in the peripheral edge of the notch portion  43  and a portion intersecting the notch portion  43  of the base plate  25  in the edge of the opening  24 . Further, the plucking hole  27  is opened in a size in which the wet tissue  22   a  of the folded wet tissue body  22  accommodated in the bag body  23  may be plucked. Further, the plucking hole  27  includes the extension portion  27   a.    
         [0082]    The attachment hole  28  is used to attach the extraction hole forming member  32  to be described later thereto, and is opened to the base plate body  25   a . The attachment hole  28  is formed so as to communicate with the notch portion  43  through the notch extension portion  43   a , and is formed in a size and a shape in which the extraction hole forming member  32  may be locked. 
         [0083]    The extraction hole forming member  32  is formed by an elastic material that is softer than the base plate body  25   a  since the extraction hole forming portion is formed in the base plate  25 . An existing known elastic material may be arbitrarily used in the extraction hole forming member  32 , but it is desirable to use a rubber material such as natural rubber and synthetic rubber or an elastic material such as PP (polypropylene), PE (polyethylene), and vinyl resin from the viewpoint of the easy elastic deformation. Further, it is desirable to use silicon rubber or urethane rubber in a case where synthetic rubber is used. 
         [0084]    As illustrated in  FIG. 7 , an extraction hole  36  is formed at the center portion of the extraction hole forming member  32  so as to serve as a through-hole formed in a substantially circular shape in the top view of the extraction hole forming member  32  and a slit  37  is formed by notching the extraction hole forming member from the extraction hole  36  toward the outer peripheral surface. A groove  33  is formed in the extraction hole forming member  32  so as to form an orbit moving around the outer peripheral surface. Further, the groove  33  intersects the slit  37 , and the groove  33  is not formed at the intersection portion. 
         [0085]    The base plate  25  is formed by fitting and locking the extraction hole forming member  32  to the attachment hole  28  of the base plate body  25   a  as below. That is, since an edge  34  of the attachment hole  28  of the base plate  25  is fitted to the groove  33  of the extraction hole forming member  32 , the extraction hole forming member  32  is attached to the base plate  25  so as not to move freely in the up-down direction, the front-back direction, and the left-right direction. 
         [0086]    Further, the extraction hole forming member  32  is fitted to the attachment hole  28  of the base plate body  25   a  while the formation position of the slit  37  matches the formation position of the notch extension portion  43   a  in the top view of the base plate  25 . At this time, the base plate  25  is formed so that the notch portion  43  communicates with the extraction hole  36 . Then, when the base plate  25  is attached to the bag body  23  so that the plucking hole  27  is formed by a part of the opening  24  of the bag body  23  and the notch portion  43 , the plucking hole  27  communicates with the extraction hole  36 . 
         [0087]    According to the wet tissue package  21 , since the plucking hole  27  and the extraction hole  36  are formed, the user may easily extract the wet tissue  22   a  while maintaining a state where the wet tissue  2   a  is not wrinkled, and hence the complicatedness in the operation of drawing out the wet tissue  2   a  and the complicatedness in use may be largely solved. Further, according to the wet tissue package  21  of this embodiment, since the extraction hole  36  is formed in the extraction hole forming portion formed of the elastic material, the hole diameter of the extraction hole  36  may be changed in response to the thickness of the wet tissue  22   a  passing through the extraction hole  36 . Accordingly, when the user draws out the wet tissue  22   a , the user may not feel a change in resistance caused by a change in the thickness of the wet tissue  22   a , and may smoothly draw out the wet tissue  22   a.    
         [0088]    (Another Example of Extraction Hole Forming Member  32 ) 
         [0089]    The extraction hole forming member  32  is not limited to the member provided with the extraction hole  36  that has a substantially circular shape in the plan view as described above. The extraction hole forming member  32  may be a member provided with the extraction hole  36  which is easily and elastically deformed and is formed so that the wet tissue  22   a  is reliably separated at the planned separation portion when the wet tissue is drawn out. For example, extraction hole forming members  45 ,  46 ,  47 , or  48  respectively having the extraction holes in the shapes illustrated in the respective views of  FIG. 8  may be attached to the base plate body  25   a  instead of the extraction hole forming member  36 . Furthermore, it is assumed that the up-down direction and the left-right direction used to describe the configuration according to the modified example of the extraction hole forming member indicate the directions illustrated in  FIG. 8 . 
         [0090]    Specifically, the extraction hole forming member  45  with the extraction hole illustrated in  FIG. 8A  will be described. The extraction hole of the extraction hole forming member  45  is formed in a manner such that a substantially circular center hole  45   a  is opened to the center portion thereof and an elongated hole portion  45   b  is formed at each of the left and right sides of the center hole  45   a . Then, the extraction hole forming member  45  is provided with a slit  45   c  that is provided below the center hole  45   a . The slit is provided to the outer peripheral edge of the extraction hole forming member  45 , and is disposed at the formation position of the notch extension portion  43   b  when the extraction hole forming member is attached to the base plate  25 . 
         [0091]    In the example of  FIG. 8B , the extraction hole of the extraction hole forming member  46  is formed by three elongated hole portions  46   a . The elongated hole portions  46   a  are formed at the interval of 120°. Further, a slit  46   b  is provided from a center portion  46   c  corresponding to the intersection of three elongated hole portions  46   a  to the outer peripheral edge of the extraction hole forming member  46 . 
         [0092]    In the example of  FIG. 8C , the extraction hole of the extraction hole forming member  47  is formed so that three linear slits  47   a  formed at the interval of 90° intersect one another, and a slit  47   b  that extends to the outer peripheral edge of the extraction hole forming member  47  is formed so as to extend from the intersection point of three slits  47   a.    
         [0093]    In the example of  FIG. 8D , the extraction hole forming member  48  is provided with a rectangular extraction hole  48   a . The extraction hole  48   a  may be formed in a rectangular shape, a rhombic shape, or a square shape. Further, a slit  48   b  is formed at the lower portion of the extraction hole  48   a  so as to extend from the extraction hole  48   a  to the outer peripheral edge of the extraction hole forming member  48 . 
         [0094]    (Another Example 1 of Base Plate) 
         [0095]    In the wet tissue package  21 , the base plate that is attached to the position of the opening  24  is not limited to the base plate  25 . In the wet tissue package  21 , a base plate  71  may be attached to the opening  24  instead of the base plate  25  as illustrated in  FIGS. 9 and 10 .  FIG. 9  is an external perspective view illustrating the external configuration of the base plate  71 , and  FIG. 10  is an exploded perspective view illustrating the configuration of the rear surface of the base plate  71 . 
         [0096]    (Configuration of Base Plate  71 ) 
         [0097]    The base plate  71  is formed so that an extraction hole forming member  83  is attached to a base plate body  71   a  and the portion provided with the extraction hole forming member  83  forms the extraction hole forming portion. The base plate body  71   a  is formed of a thermoplastic resin material such as polyethylene and polypropylene, and is molded by an existing molding method. As illustrated in  FIG. 9 , the base plate body  71   a  is formed in an outline shape in which a compact having a substantially oval shape in the top view is partially notched inward from the outer peripheral edge thereof so as to have a predetermined size. At this time, the notched portion forms the notch portion  43 , and the recessed portion  44  is formed in the outer peripheral edge of the base plate  25 . Further, the base plate  71  is attached to the bag body  23  at the peripheral edge of the base plate body  71   a  by an arbitrary method using hot-melt or the like, and an adhesion surface  72  is formed in the peripheral edge thereof. At this time, the plucking hole  27  is formed by a part of the edge of the opening  24  of the bag body and the notch portion  43  of the base plate  71  while the base plate  71  is attached to the bag body  23 . In the base plate  71 , a portion is formed at the inside of the adhesion surface  72  of the base plate body  71   a  so as to be depressed in relation to the adhesion surface  72 , and the depressed portion forms a concave portion  73 . The concave portion  73  is provided with an opening hole  75 . Further, in the notch portion  43  of the base plate  71 , the tapered portion is provided with the notch extension portion  43   a , and the tapered end of the notch extension portion  43   a  reaches the opening hole  75 .
