Title: Packaging container and method for using same

Description:
TECHNICAL FIELD 
     The present invention relates to a packaging container and a method for using same for containing water absorptive contents such as a portable wet sheet impregnated with a liquid such as water or skin lotion. 
     BACKGROUND ART 
     Conventionally, packaging containers for containing water absorptive contents in which a liquid is impregnated, include a container containing wet sheets as contents impregnated with a chemical liquid or the like. This wet sheet is convenient for childcare, medical care/nursing such as a cosmetic purpose, removing dirt and sweat of skin, care of the area surrounding a mouth, oral care, treatment of defecation and the like, and a variety of uses such as keeping a pet, cleaning a floor, a desk and an automobile so that the wet sheet is preferably used at ordinary homes, in a medical care site and so forth. As compared with usual dry sheets, this type of wet sheets is particularly effective because a stuck cosmetic material or dust can easily and quickly be wiped out and surely removed. 
     Conventional wet sheets are contained in a bag-shaped, box-shaped or cylindrical container which is provided with an opening formed to take out the wet sheet, and a lid member or a repeelable seal member for closing the opening which can be tightly closed to prevent the wet sheets from being dried. In accordance with this structure, since a wet sheet is taken out from the opening by wide opening the lid member or the seal member each time the wet sheet is used, there is a problem that a chemical liquid of the wet sheets is evaporated each time the wet sheet is used so that the wet sheets tend to be dried. Particularly, in the case of a soft packaging bag such as a portable bag, as compared with a hard box type or cylinder type wet sheet container, it is difficult to re-attach the lid member or the seal member in order to tightly seal up the opening. 
     In order to solve such a problem, as described in Patent Document 1, a packaging structure from which wet sheets can be taken out without opening a lid member is proposed. Namely, a wet sheet can be taken out without the need for peeling the seal member by providing a plurality of a first opening and a second opening on a packaging bag and having the wet sheet successively pass through the two openings. Furthermore, in the case of Patent Document 1, after taking out a wet sheet, the next wet sheet is exposed from a take-out port with only its head out so that the wet sheet can be successively taken out by gripping the head. Accordingly, it is possible to decrease the open area through which a wet sheet is taken out and prevent the wet sheet from being dried.

     SUMMARY OF THE INVENTION 
     Problems to be Solved by the Invention 
     However, in the case of the packaging container disclosed in Patent Document 1, wet sheets are impregnated in a liquid while the wet sheets are contained in the packaging container before opening so that, in such a wet condition as compared with a dry condition, sundry bacteria and virus can easily adhere and proliferate so that sanitation is deteriorated. Contrary to this, in a conventional method as employed, an antiseptic agent, a bactericide, an antimicrobial agent or the like agent is blended. However, since a wet sheet or the like is used to be in direct contact with skins, blending a stimulating reagent, such as a preservative, may cause troubles such as allergy or rough skin depending upon user&#39;s constitution. 
     In order to solve the problem as described above, it is therefore an object of the present invention to provide a packaging container and a method for using same in which the packaging container contains water absorptive contents to be impregnated with a liquid such that the contents can be hygienically stored without making use of a stimulating reagent such as a preservative. 
     Means for Solving Problem 
     In order to accomplish the object as described above, the present invention is related to a packaging container which contains a water absorptive content to be impregnated with a liquid, comprising: 
     a container body provided with an opening and closing section which can be opened and closed; 
     a liquid enclosure member which is disposed in the container body and in which the liquid is enclosed; 
     a bag body disposed in the container body with the content which is enclosed therein; 
     a pullout portion which is a part of the bag body and to be pulled out through the opening and closing section; and 
     a rupture section formed on a part of the bag body to rupture the bag body. 
     In accordance with the present invention, the water absorptive content is contained in the bag body in a dried state, and this bag body is further disposed in the container body. The water absorptive content is contained in the bag body in a dried state before opening, and the liquid enclosure member in which the liquid is enclosed is disposed separately from this bag body  30  in the container body, with the opening and closing section being sealed to provide a finished product. Then, when the product is used, first, the liquid contained in the liquid enclosure member is let flow into the inside of the container body by giving damage to the liquid enclosure member such as crushing to rupture the liquid enclosure member in advance of opening the opening and closing section. At this time, the content is contained in the bag body in a dried state, and not impregnated with the flowing liquid. In this state, after the liquid is diffused in the container body by kneading and shaking the container body, the opening and closing section is opened, and the pullout portion is pulled out from the inside of the container body. By this procedure, the water absorptive content in the bag body is exposed out of the bag body and impregnated with the surrounding liquid by absorption. The ruptured bag body can be taken out by pulling out the pullout portion through the opening and closing section with the content remaining in the container body. 
     In accordance with the present invention as described above, since the water absorptive content is contained in the bag body in a dried state before opening, and the liquid enclosure member in which the liquid is enclosed is disposed separately from this bag body in the container body, the content are not impregnated with the liquid, and it is possible to prevent sundry bacteria and virus from adhering and proliferating and improve sanitation while the content is contained in the packaging container before opening. Also, since the liquid is enclosed in the liquid enclosure member and isolated from outside air, there is no need for blending a stimulating reagent such as an antiseptic agent, a bactericide or an antimicrobial agent. Because of this, in accordance with the present invention, troubles such as allergy or rough skin can be prevented even if the contents are wet sheets or the like which is used in direct contact with skin. 
     Meanwhile, the above liquid used in the case of the present invention may be a variety of liquid components as long as troubles such as allergy or rough skin are not caused. Examples of such liquid components include tap water, distilled water, hard water, medium-hard water, soft water and super hard water, and also include function water or functional water such as hydrogen water, reduced water, natural water, pure water, raw water, electrolysis water, oxygen water, deep sea water, alkali ionized water, carbonated water, foam water, or still water. 
     Furthermore, in accordance with the present invention as described above, when the content is used, it is possible to cause the liquid contained in the liquid enclosure member to flow into the inside of the container body by giving damage such as pressing to rupture the liquid enclosure member in advance of opening the opening and closing section. Then, after the liquid is sufficiently diffused in the container body by kneading and shaking the container body, the content can be exposed out of the bag body by rupturing the bag body, and fully impregnated with the surrounding liquid. 
     In the case of the above invention, it is preferred that an admixture disposed outside of the bag body and provided to be mixed with the liquid enclosed in the liquid enclosure member. This admixture includes, for example, a flavoring agent, a reagent, a surface active agent, a moisturizing agent, a deodorizing agent, a preserving agent/bactericide, an exothermic agent, a coolant and the like. These materials can be used as a water solution or mixture thereof, an organic solution or solvent thereof, a capsule filled with these materials, freeze-dried powders, a solidified film, or any other preferred known form, and used as a mixture with the above described liquid component such as water. 
     In this case, in an unopened condition, since the component to be mixed with the liquid can be stored in a state separate from the liquid, it is possible to prevent the degradation of the component, the proliferation of sundry bacteria and virus and so forth to retain the freshness of the components, and further improve sanitation. Particularly, in the case of the present invention, since the liquid contained in the liquid enclosure member is caused to flow into the container body just before opening the opening and closing section, the liquid contained in the container body can be fully mixed with the admixture by kneading and shaking the container body to sufficiently diffuse the mixed liquid around the content and impregnate the content with the mixed liquid so that the content can uniformly absorb the liquid mixed with the admixture. 
     In the case of the above invention, it is preferred that the opening and closing section is constructed by an opening communicating with the inside of the container body, and a re-adhesive seal member which is located on the outside surface of the container body to close the opening. In this case, since the opening is closed by the re-adhesive seal member, it is possible to maintain an internal wet state even if the opening is repeatedly opened and closed and prevent sundry bacteria and virus from entering. 
     In the case of the above invention, it is preferred that the opening and closing section is constructed by an opening communicating with the inside of the container body, and a cap member in the form of a cap which is threaded into the opening to close the opening on the outside surface of the container body. In this case, since the opening is closed by the cap member which is threadedly engaged with the opening, it is possible to maintain an internal wet state even if the opening is repeatedly opened and closed and prevent sundry bacteria and virus from entering. 
     Furthermore, in the case of the above invention, it is preferred that the container body is provided with an opening section which is opened along a cut-off line and which is provided with a sealing section to seal the opening section, and that the pullout portion is releasably fixed to a member which is used to close the opening. In this case, the pullout portion of the bag body can be pulled out from the container body by the operation of opening the seal member or the cap member as described above, and therefore it is possible to dispense with a tedious operation of picking up the pullout portion through the opening and improve the user-friendliness of the product. Furthermore, with the opening section which is opened along a cut-off line, the content can easily be taken out by opening the opening section, and with the sealing section to close the opening section, it is possible to maintain an internal wet state even if the opening is opened and prevent sundry bacteria and virus from entering. 
     Effects of the Invention 
     In accordance with the packaging container of the present invention, as has been discussed above, since the content is not impregnated with the liquid before opening, it is possible to prevent sundry bacteria and virus from adhering to and proliferating on the content before opening, and since the liquid is enclosed in the liquid enclosure member and isolated from outside air, there is no need for blending a stimulating reagent such as an antiseptic agent, a bactericide or an antimicrobial agent. Because of this, in accordance with the present invention, the content can be hygienically provided while preventing troubles such as allergy or rough skin even if the contents are wet sheets or the like which is used in direct contact with skin.

     MODE FOR CARRYING OUT THE INVENTION 
     First Embodiment 
     (Overall Configuration of Packaging Container) 
     In what follows, with reference to the accompanying drawings, a first embodiment of a packaging container in accordance with the present invention will be explained in detail.  FIG. 1  is a perspective view for showing the overall configuration of the packaging container in accordance with the present embodiment, and  FIG. 2  is a cross sectional side view thereof. 
     The packaging container  1  in accordance with the present embodiment can contain wet sheets or the like impregnated with a chemical liquid or the like, and can be used for childcare, medical care/nursing such as a cosmetic purpose, removing dirt and sweat of skin, care of the area surrounding a mouth, oral care, treatment of defecation and the like, and a variety of uses such as keeping a pet, cleaning a floor, a desk and an automobile. Specifically, as illustrated in  FIG. 1  and  FIG. 2 , the packaging container  1  is generally composed of an internally hollow container body  10  which is a base element of the overall configuration and provided with a seal member  42  as an opening and closing section, a liquid enclosure member  50   a  disposed inside the container body  10 , and a bag body  30 . 
     The container body  10  is a rectangular package having the seal member  42 , which can be opened or closed, and formed as a rectangular internally hollow container by heat bonding the perimeter and end portions  10   a  of a sheet made of aluminum, vinyl or the like material having high water resistance. 
     The contents  11  contained in the container body  10  are, for example, a vegetable fiber such as pulp, cotton or hemp, an animal fiber such as wool or silk, a regenerated fiber such as rayon or cupra, a half-synthetic fiber such as acetate or promix, a nonwoven fabric made of synthetic fiber or the like, paper made of natural pulp, synthetic pulp, or cloth made of gauze or the like in the form of a sheet material having wet strength, which is contained in a dry state. 
     The bag body  30  is an airtight bag body which is accommodated in the container body  10  and in which is enclosed the contents  11 . The bag body  30  is made for example of thin vinyl, aluminum foil or the like. In the case of the present embodiment, the contents  11  such as water absorptive wet sheets in a dried state are contained in this bag body  30 , which is in turn located in the container body  10  with the contents  11  contained therein. 
     In the case of the present embodiment, this bag body  30  includes a pullout portion  31  which is pulled out through an opening  41  and a rupture section  30   b  where the bag body  30  can be ruptured. The pullout portion  31  can be a salient portion, for example, a corner of the bag body  30 , or a welding portion which is formed when the bag body  30  is formed by sticking. The rupture section  30   b  may be formed, for example, as a break line such as a perforation line formed in the bottom surface of the bag body, or a cut portion having a decreased thickness. 
     Furthermore, in the case of the present embodiment, a cutoff line  30   a  is formed on the bag body  30  for cutting off the pullout portion  31 . As illustrated in  FIG. 3 , after pulling out the pullout portion  31  and rupturing the rupture section  30   b  in the bottom side, the pullout portion  31  is torn off and removed along the cutoff line  30   a  with the main body of the bag body  30  remaining in the container body  10 . An opening is formed in the upper side of the bag body  30  by cutting off the pullout portion  31  in this manner in order that a liquid is allowed to flow into the bottom side of the bag body through this opening, and that the contents can be taken out through the opening formed by cutting off the pullout portion without the need for removing the bag body  30 . 
     The seal member  42 , which serves as an opening and closing section, is a flexible member which is located in the upper side of the container body  10  and can be opened and closed. In the case of the present embodiment, the seal member  42  is a re-adhesive seal member which is located on the outside surface of the container body  10  and can close the opening  41  communicating with the inside of the container body  10 . Meanwhile, in the case where the container body is bag-shaped, this opening and closing section is formed on the upper opening of the bag body, and this upper opening of the bag body can be openably closed, for example, with a chuck or zipper (trademark). 
     The opening  41  is a hole in the shape of a rectangle, an oval or the like having such an area that the contents  11  impregnated with a liquid can be picked up. The seal member  42  is made of a sealing material such as a re-attachable vinyl to which an adhesive is applied so that, since the opening  41  is closed by releasably attaching the seal member  42  to the perimeter of the opening  41 , it is possible to maintain an internal wet state even if the opening  41  is repeatedly opened and closed and prevent sundry bacteria and virus from entering. 
     Alternatively, the pullout portion  31  may be releasably fixed to the seal member  42 . In this case, the pullout portion  31  of the bag body  30  can be pulled out from the container body  10  by the operation of opening the seal member  42 , and therefore it is possible to dispense with a tedious operation of picking up the pullout portion  31  through the opening  41  and improve the user-friendliness of the product. 
     The liquid enclosure member  50   a  is a simple container which is disposed in the container body  10  and in which is enclosed a liquid which is isolated from outside air. As this liquid enclosure member  50   a , a plastic bag, a vacuum pack, a capsule, a plastic vessel can be adopted as long as a liquid can be sealed therein. While the bag body  30  is contained in the container body  10 , this liquid enclosure member  50   a  is disposed separately from the bag body  30 . This liquid enclosure member  50   a  is arranged in order to be crushed and ruptured due to a pressure force applied by giving damage to the liquid enclosure member  50   a , such as pressing in the container body  10 , in advance of opening to make the liquid contained therein flow into the inside of the container body  10 . 
     Furthermore, in the case of the present embodiment, an admixture  50   b  is disposed inside the packaging container  1  and outside the bag body  30 . This admixture  50   b  includes, for example, a cosmetic material, a medicine, a flavoring agent, a reagent, a surface active agent, a moisturizing agent, a deodorizing agent, a preserving agent/bactericide, an exothermic agent, a coolant and the like. These materials can be used as a water solution or mixture thereof, an organic solution or solvent thereof, a capsule filled with these materials, freeze-dried powders, a solidified film, or any other preferred known form, and used as a mixture with the above described liquid component such as water. 
     (Using Method) 
     Next, the using method of the above described packaging container will be explained.  FIGS. 4A-4D  are cross sectional side views for showing the use state of the packaging container in accordance with the present embodiment. The packaging container  1  in accordance with the present embodiment includes, as illustrated in  FIG. 4A , the water absorptive contents  11  are contained in the bag body  30  in a dried state before opening, and the liquid enclosure member  50   a  in which a liquid  12  is enclosed is disposed separately from this bag body  30  in the container body  10 , with the opening and closing section being sealed to provide a finished product. 
     Then, when the product is used, as illustrated in  FIG. 4B , at first, a pressure force is applied to the liquid enclosure member  50   a  in advance of opening the opening and closing section to rupture the liquid enclosure member  50   a  by giving damage to the liquid enclosure member  50   a  to make the liquid  12  contained in the liquid enclosure member  50   a  flow into the inside of the container body  10  in which the dried water absorptive contents  11  are contained. At this time, the contents are contained in the bag body in a dried state, and not impregnated with the flowing liquid. Meanwhile, in the case where the admixture  50   b  is used, the liquid  12  is fully mixed with the admixture  50   b  by kneading and shaking the container body  10  to sufficiently diffuse the mixed liquid around the contents  11 . 
     Next, as illustrated in  FIG. 4C , the opening  41  is opened by peeling the seal member  42 , and the exposed pullout portion  31  is gripped and pulled out with fingers. Then, in the container body  10 , the rupture section  30   b  is broken by pulling out part or the entirety of the bag body  30  from the opening  41 , and the contents  11  are exposed out of the bag body  30  and impregnated with the surrounding liquid by absorption. The broken bag body  30  can be taken out by pulling out the pullout portion  31  through the opening  41  with the contents  11  remaining in the container body  10 . 
     Alternatively, as illustrated in  FIG. 3 , the bag body  30  can be left in the container body  10  by tearing the pullout portion  31  along the cutoff line  30   a  after pulling out the pullout portion  31  and rupturing the rupture section  30   b  in the bottom side. An opening is formed in the upper side of the bag body  30  by cutting off the pullout portion  31  in this manner in order that a liquid is allowed to flow into the bottom side of the bag body through this opening, and that the contents  11  can be taken out through the opening formed by cutting off the pullout portion without the need for removing the bag body  30 . In storage thereafter, as illustrated in  FIG. 4D , the inside liquid is prevented from evaporating by closing the seal member  42 . 
     (Actions/Effects) 
     In accordance with the present embodiment as described above, since the water absorptive contents  11  are contained in the bag body  30  in a dried state before opening, and the liquid enclosure member  50   a  in which the liquid  12  is enclosed is disposed separately from this bag body  30  in the container body  10 , the contents  11  are not impregnated with the liquid  12 , and it is possible to prevent sundry bacteria and virus from adhering and proliferating and improve sanitation while the contents  11  are contained in the container body  10  before opening. Also, since the liquid  12  is enclosed in the liquid enclosure member  50   a  and isolated from outside air, there is no need for blending a stimulating reagent such as an antiseptic agent, a bactericide or an antimicrobial agent, and troubles such as allergy or rough skin can be prevented even if the contents  11  are wet sheets or the like which is used in direct contact with skin. 
     Furthermore, when the contents  11  is used, it is possible to cause the liquid  12  contained in the liquid enclosure member  50   a  to flow into the inside of the container body  10  by giving damage such as pressing to rupture the liquid enclosure member  50   a  in advance of opening the seal member  42 . Then, after the liquid  12  is sufficiently diffused in the container body  10  by kneading and shaking the container body  10 , the contents  11  can be exposed out of the bag body  30  by pulling and removing the bag body  30 , and fully impregnated with the surrounding liquid  12 . 
     Furthermore, in accordance with the present embodiment as described above, the admixture  50   b  to be mixed with the liquid  12  contained in the liquid enclosure member  50   a  is further disposed outside of the bag body  30  so that, in an unopened condition, the component to be mixed with the liquid  12  can be stored in a state separate from the liquid  12 , and therefore it is possible to prevent the degradation of the component, the proliferation of sundry bacteria and virus and so forth to retain the freshness of the components, and further improve sanitation. Particularly, in the case of the present invention, since the liquid  12  contained in the liquid enclosure member  50   a  is caused to flow into the container body  10  just before opening the seal member  42 , the liquid contained in the container body  10  is fully mixed with the admixture  50   b  by kneading and shaking the container body  10  to sufficiently diffuse the mixed liquid around the contents  11  and impregnate the contents  11  with the mixed liquid, and thereby the contents can uniformly absorb the liquid mixed with the admixture  50   b.    
     Second Embodiment 
     In what follows, with reference to the accompanying drawings, a second embodiment of a packaging container in accordance with the present invention will be explained in detail.  FIGS. 5A and 5B  are transparent front views of the overall configuration of the packaging container in accordance with the second embodiment, and  FIG. 6  is a transparent perspective view for showing the overall configuration of the packaging container in accordance with the second embodiment. Meanwhile, in the description of the present embodiment, like reference numbers indicate functionally similar elements as the above embodiment unless otherwise specified, and therefore no redundant description is repeated. 
     (Structure of Packaging Container) 
     As illustrated in  FIG. 5A  and  FIG. 6 , in the case of the present embodiment, a pack container  60  is provided with a cap which is used to close a container body thereof. An opening and closing section is formed by an opening  41  communicating with a hollow space  63  inside of the pack container  60  and a cap member  43  in the form of a cap which is threaded into the opening  41  to close the opening  41  on the outside surface of the container body  10 . 
     The opening  41  can be opened and closed with the cap member  43  and used to additionally inject an admixture, a reagent, a cosmetic material or the like therethrough. By this procedure, the ingredients of the liquid contained in the container can be customized. Incidentally, the opening  41  and the cap member  43  can be located not only in the position as illustrated in the same figure (a), but also in such a position that the opening  41  is formed inclined on one side of an upper part of the pack container  60  as illustrated in the same figure ( b ). 
     The above pullout portion  31  may be releasably fixed to the cap member  43 . In this case, the pullout portion  31  of the bag body  30  can be pulled out from the container body  10  by the operation of opening the cap member  43 , and therefore it is possible to dispense with a tedious operation of picking up the pullout portion  31  through the opening  41  and improve the user-friendliness of the product. 
     Furthermore, in the case of the present embodiment, the pack container  60  is formed with an opening section  64  which can be torn from a notch  64   a  along a cut-off line  64   b  to open the pack container  60 . This opening section  64  is provided with a zipper (trademark), a chuck or the like sealing section  44  to openably seal the opening. This sealing section is used to airtightly seal the opening of the opening section with a chuck or the like. 
     (Using Method 1) 
     The packaging container having the structure as described above can be used by the using method of the present invention.  FIGS. 7A-7E  are explanatory views for showing the using method 1 in accordance with the present embodiment. In this using method, as illustrated in  FIG. 7A , the bag body  30  contains the water absorptive contents  11  in a dried state before opening, and the liquid enclosure member  50   a  in which a liquid  12  is enclosed is disposed in the container body  10  separately from this bag body  30 , with the opening and closing section being sealed with the cap member  43  to provide a finished product. 
     Then, when the product is used, as illustrated in  FIG. 7B , at first, a pressure force is applied to the liquid enclosure member  50   a  in advance of opening the opening and closing section to rupture the liquid enclosure member  50   a  by giving damage to the liquid enclosure member  50   a  to make the liquid  12  contained in the liquid enclosure member  50   a  flow into the inside of the container body  10  in which the dried water absorptive contents  11  is contained. At this time, the contents are contained in the bag body in a dried state, and not impregnated with the flowing liquid. Meanwhile, in the case where the admixture  50   b  is used, the liquid  12  is fully mixed with the admixture  50   b  by kneading and shaking the container body  10  to sufficiently diffuse the mixed liquid around the contents  11 . At this time, after removing the cap member  43  from the opening  41 , an admixture, a reagent, a cosmetic material or the like can be additionally injected through the opening  41  to customize the ingredients of the liquid contained in the container. 
     Next, as illustrated in  FIG. 7C , the opening  41  is opened by removing the cap member  43 , and the exposed pullout portion  31  is gripped and pulled out with fingers. Then, in the container body  10 , the rupture section  30   b  is broken by pulling out the entirety of the bag body  30  from the opening  41 , and the contents  11  is exposed out of the bag body  30  and impregnated with the surrounding liquid by absorption as illustrated in  FIG. 7D . 
     Thereafter, as illustrated in  FIG. 7E , the opening section is opened by rupturing and removing an upper portion of the pack container  60  from the cut-off line  64   b , and the broken bag body  30  is pulled and taken out with the contents  11  remaining in the container body  10 . This opening section  64  can be opened and closed by the sealing section  44  such as a chuck so that the contents  11  can readily be taken out and used by opening the sealing section  44 . In storage thereafter, the inside liquid is prevented from evaporating by sealing the sealing section  44  of the opening section  64 . 
     (Using Method 2) 
     Next, another using method will be explained.  FIGS. 8A-8E  are explanatory views for showing the using method 2 in accordance with the present embodiment. As illustrated in  FIG. 8A , a water absorptive content  14 , which is made compact, is suspended with a thread  14   a  and contained in the bag body  30  in a dried state before opening the packaging container in accordance with this using method, and the liquid enclosure member  50   a  in which a liquid  12  is enclosed is disposed separately from this bag body  30  in the container body  10 , with the opening and closing section being sealed by the cap member  43  to provide a finished product. Incidentally, the content  14  may be a mask or sheet which is used to entirely or partly cover a face, a neck or a body. 
     Then, when the product is used, as illustrated in  FIG. 8B , at first, the liquid enclosure member  50   a  is broken by giving damage such as applying a pressure force to rupture the liquid enclosure member  50   a  to make the liquid  12  contained in the liquid enclosure member  50   a  flow into the inside of the container body  10  in which the dried water absorptive content  14  is contained. At this time, the content is contained in the bag body in a dried state, and not impregnated with the flowing liquid. Meanwhile, in the case where the admixture  50   b  is used, the liquid  12  is fully mixed with the admixture  50   b  by kneading and shaking the container body  10  to sufficiently diffuse the mixed liquid around the content  14 . At this time, after removing the cap member  43  from the opening  41 , an admixture, a reagent, a cosmetic material or the like can be additionally injected through the opening  41  to customize the ingredients of the liquid contained in the container. 
     Next, as illustrated in  FIG. 8C , the opening  41  is opened by removing the cap member  43 , and the exposed pullout portion  31  is gripped and pulled out with fingers. Then, in the container body  10 , the rupture section  30   b  is broken by pulling out the entirety of the bag body  30  from the opening  41 , and the content  14  is exposed out of the bag body  30  and impregnated with the surrounding liquid by absorption as illustrated in  FIG. 8C . By this process, the content  14  absorbs liquid and expands to recover the original size of a face mask. 
     Thereafter, as illustrated in  FIG. 8E , the opening section is opened by rupturing and removing an upper portion of the pack container  60  from the cut-off line  64   b , and the broken bag body  30  is pulled and taken out with the content  14  remaining in the container body  10 . This opening section  64  can be opened and closed by the sealing section  44  such as a chuck so that the content  14  can readily be taken out and used by opening the sealing section  44 . In storage thereafter, the inside liquid is prevented from evaporating by sealing the sealing section  44  of the opening section. 
     Incidentally, while the content  14  is suspended in the bag body  30  with the thread  14   a  in accordance with the using method 2 as explained above, the bag body  30  can be dispensed with because the content  14  is prevented by the thread  14   a  from coming in contact with the liquid  12  before opening. On the other hand, in the case where the content  14  is prevented by the bag body  30  from coming in contact with the liquid  12  before opening, the thread  14   a  may be dispensed with. 
     (Actions/Effects) 
     In accordance with the present embodiment as explained above, since the opening  41  is closed by the cap member  43  which is threadedly engaged with the opening  41 , it is possible to maintain an internal wet state even if the opening  41  is repeatedly opened and closed and prevent sundry bacteria and virus from entering. In addition, the opening  41  can be opened and closed with the cap member  43  and used to additionally inject an admixture, a reagent, a cosmetic material or the like therethrough, and thereby it is possible to customize the ingredients of the liquid contained in the container. 
     Furthermore, in accordance with the present embodiment, the pullout portion  31  of the bag body  30  can be pulled out from the container body  10  by the operation of opening the cap member  43 , and therefore it is possible to dispense with a tedious operation of picking up the pullout portion  31  through the opening  41  and improve the user-friendliness of the product. 
     Modification Example 
     Incidentally, the embodiments as described above are examples of the present invention. Because of this, the present invention is not limited to the above embodiments, and various modifications are possible in accordance with the design and so forth without departing from the technical spirit of the invention. For example, while the cap and the seal are used in the embodiments as described above, such cap and seal can be omitted as a disposable type which is opened simply by tearing and removing part of the container, or as a resealable type having a chuck, zipper or the like for opening.
