A wet tissue packaging unit provided with: a storage container, which is capable of storing a continuous body of wet tissues in which separating parts are formed at each of prescribed intervals; a take-out port formation member having a take-out port formation part, which is attached to the opening of the storage container and in which is formed a take-out port for imparting resistance when the continuous body of wet tissues passes therethrough, and a storage space capable of storing the leading end of the continuous body of wet tissues that passed through the take-out port; and a cover section that freely opens and closes from the outside of the storage space, wherein there is provided a linking part for linking the storage space of the take-out port formation member and the space inside the storage container in an area other than the take-out port.
The present invention relates to a wet tissue packaging unit that accommodates and packs a wet tissue continuing material body formed by a plurality of wet tissues, in an accommodation container.
BACKGROUND ARTHitherto, a wet tissue used for wiping hands or buttocks of babies, patients, and elderly people is widely known. The wet tissue is formed by impregnating a chemical solution and the like into a ground fabric. The wet tissue is 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, and is formed to be extracted from the accommodation container as needed basis.
As the accommodation container, a cylindrical bottle type container has been widely used from the past. In many cases, the bottle type accommodation container accommodates a wet tissue continuing material body which is wound in a roll shape. The wet tissue continuing material body is provided with separating portions (i.e., dividing portions) by breaks of perforation lines or the like at predetermined intervals, and when the wet tissue continuing material body is divided at the dividing portion by cutting a part of the wet tissue continuing material body at the dividing portion or the like, a sheet-like wet tissue is obtained.
In recent years, instead of the bottle type wet tissue packaging unit, a bag type wet tissue packaging unit provided with a bag-like accommodation container has been used in many cases. The bag type wet tissue packaging unit accommodates an interfolded wet tissue continuing material body in a bag body and is formed so that wet tissues forming the wet tissue continuing material body are extracted to the outside from an opening which is opened to the bag body. The opening of the bag body is formed so that a wet tissue is separated from the wet tissue continuing material body at the dividing portion formed in the wet tissue continuing material body. Further, the bag body is generally provided with a lid for opening and closing the opening. As the lid, for example, a flap-like lid which is formed by a film material such a material of the bag body has been widely used (e.g., Patent Literatures 1 and 2).
CITATION LIST Patent Literatures Patent Literature 1: JP 2004-196303 A Patent Literature 2: JP 2010-173649 A SUMMARY OF INVENTION Technical ProblemIn the bag type wet tissue packaging unit formed as described above, the lid is attached to the vicinity of the surface of the bag body to close the opening when a user does not extract a wet tissue. In the wet tissue packaging unit, the inside of the bag body is kept in a sealed state by the lid such that the chemical solution and the like impregnated into the wet tissue accommodated in the bag body are prevented from volatilizing.
In addition, at a position inside the lid, an extraction hole which applies a friction resistance to the wet tissue continuing material body when the wet tissue packaging unit is drawn out while passing therethrough is formed. Then, when a predetermined or higher resistance is applied to the wet tissue continuing material body during the extraction, the wet tissue continuing material body is divided at the dividing portion, which is close to the drawing end, due to the resistance.
However, in the bag type wet tissue packaging unit, when the wet tissue is consumed, the volume of the wet tissue continuing material body inside the bag body decreases, the wet tissue continuing material body easily passes and hence the timing at which the wet tissue is divided at the dividing portion is delayed. Then, the front end of the wet tissue continuing material body that is divided and remains is excessively drawn out from the opening which has to be sealed by the lid, and the wet tissue packaging unit may not be reliably sealed. Accordingly, there is a problem in that the wet tissue may not be maintained in a wet state.
The present invention is made in view of such problems, and an object thereof is to provide a wet tissue packaging unit, i.e. a wet tissue package, capable of further sealing an accommodation container and maintaining a wet tissue accommodated in the accommodation container in a wet state.
Solution to ProblemThe present invention may be summarized as below.
(1) A wet tissue packaging unit including: an accommodation container that accommodates a wet tissue continuing material body having a dividing portion formed therein at a predetermined interval, and includes an opening formed to draw out a wet tissue divided from the wet tissue continuing material body at the dividing portion to the outside; an extraction hole forming member that is attached to the opening of the accommodation container and includes an extraction hole forming portion having an extraction hole formed to apply a resistance when the wet tissue continuing material body passes therethrough and an accommodation space which accommodates a front end of the wet tissue continuing material body that passes through the extraction hole; a lid that is provided at the outside of the accommodation space so as to freely close and open the accommodation space; and a communicating portion that allows the accommodation space of the extraction hole forming member and a space in the accommodation container to communicate with each other in an area excluding the extraction hole.
(2) The wet tissue packaging unit according to (1), wherein the communicating portion is provided in a peripheral edge area of a bottom portion of the accommodation space.
(3) The wet tissue packaging unit according to (2), wherein the extraction hole forming portion is formed in a plate that is convexly curved toward the inner side of the accommodation container, and the communicating portion is formed by the convexly swollen area.
(4) The wet tissue packaging unit according to any of (1) to (3), wherein the attachment hole forming portion is supported by the attachment hole forming member in a cantilevered manner, and the communicating portion is formed or is widened as a free end of the attachment hole forming portion is turned toward the internal space of the accommodation container on the cantilevered portion as the center.
(5) The wet tissue packaging unit according to (1), wherein the extraction hole forming member is attached to the accommodation container by allowing an attachment surface of the extraction hole forming member to face an inner surface of the accommodation container.
Advantageous Effects of InventionAccording to the wet tissue packaging unit of the present invention, even when the timing at which the wet tissue continuing material body is divided at the dividing portion is delayed and hence the extra front end portion of the wet tissue continuing material body is drawn out and is lengthened in the accommodation space, the front end portion of the wet tissue continuing material body may be pushed into the accommodation container through the communicating portion so as to be relieved. Since the lid is reliably closed and the accommodation container is sealed, it is possible to prevent the chemical solution and the like impregnated into the wet tissue continuing material body accommodated in the accommodation container from volatilizing. Further, according to the wet tissue packaging unit of the present invention, it is possible to provide the wet tissue in a state where the chemical solution and the like are always impregnated therein for a user.
The configuration of a first embodiment of a wet tissue packaging unit, i.e. a wet tissue package, according to the present invention will be described with reference to
As illustrated in
First, the configuration of the wet tissue continuing material body 6 will be described. In the present specification, the “wet tissue continuing material body” indicates a wet tissue continuing material body that is piled in a folded shape by a method to be described later and is accommodated in the bag body 3, and a “wet tissue” indicates both a sheet-like tissue separated from the wet tissue continuing material body 6 and a sheet-like tissue forming the wet tissue continuing material body 6. This embodiment and second to fourth embodiments to be described later are described by using a wet tissue continuing material body that is piled in a folded shape as an example of the wet tissue continuing material body, but the configuration of the wet tissue continuing material body is not limited thereto. For example, as the wet tissue continuing material body, a body that is wound in a roll shape or has the other configurations may be used.
The wet tissue continuing material body 6 is formed by impregnating a chemical solution and the like into a ground fabric formed by paper made from synthetic fabric or natural fabric, woven cloth, or non-woven cloth. As the chemical solution and the like, alcohol, water, or the mixture thereof may be exemplified. Further, the chemical solution may be arbitrarily selected from perfume, antibacterial agent, refresher, surfactant, antiseptic agent, pigment, antifoam agent, antioxidizing agent, clarifying agent, solubilizing agent, pH adjuster, and the like and mixed therewith. Furthermore, the above-described materials of the ground fabric and the chemical solution and the like forming the wet tissue continuing material body 6 are merely examples, and the materials other than the above-described materials may be arbitrarily selected to be used.
Structures of the wet tissue continuing material body 6 include both followed structures. In one kind of the structures, a wet tissue continuing material body is formed so that wet tissues are connected to each other by the perforation lines or the like, and in another kind of the structures, a wet tissue continuing material body that is formed so that each of separate wet tissues is bent and folded in a Z-shape or the like to be described later and the plurality of folded wet tissues contact one another. In addition, in the present specification, the separation of the wet tissue from the wet tissue continuing material body 6 indicates that, for example, in a case where the wet tissues are connected by the perforation lines or the like, the wet tissue continuing material body 6 is torn at the position of the perforation lines or the like and a portion that becomes the wet tissue is separated from the wet tissue continuing material body 6. Further, the separation indicates that, in a case where the wet tissue continuing material body 6 is formed to have a structure in which each of the separate wet tissues is appropriately folded in a Z-shape to be described later and the plurality of wet tissues contact one another, the front end of single wet tissue is took off from the contact portion of the plurality of wet tissues so as to be separated from the wet tissue continuing material body 6. Furthermore, a portion where the wet tissue is separated from the wet tissue continuing material body 6 is called a dividing portion.
A specific example of the wet tissue continuing material body 6 will be described. The wet tissue continuing material body 6 illustrated in
In the above-described example, the case where the separating portion 10 is formed as the dividing portion in the wet tissue continuing material body 6. However, the shape of the wet tissue continuing material body 6 is not limited thereto and may be formed in the other shapes. Specifically, as exemplified below, the wet tissue continuing material body 6 may be formed so that a predetermined portion where two folded separate wet tissues overlap each other becomes the separating portion (i.e., the dividing portion). An example of the configuration of another shape of the wet tissue continuing material body 6 is illustrated in
As illustrated in
As illustrated in
Furthermore, the configuration of the wet tissue continuing material body 6 is not limited to the above-described configuration. The configuration of the wet tissue continuing material body 6 may be formed in any shape as long as the wet tissue continuing material body may be accommodated in the bag body 3. For example, in this embodiment, the position of the separating portion 10 is located at the center portion between the first turnback portion 8 and the second turnback portion 9. However, the separating portion 10 may be disposed at a position other than the center portion. Further, the separating portion 10 may be disposed at a position where the first turnback portion 8 or the second turnback portion 9 is formed. Further, in this embodiment, as for the vertical relation of the wet tissue continuing material body 6, a portion with the separating portion 10 and a portion without the separating portion 10 are alternated. However, the portions with the separating portion 10 may overlap each other in the up-down direction. Further, the separating portion 10 may be located at both positions where the first turnback portion 8 and the second turnback portion 9 are formed. Furthermore, the separating portion may have a configuration other than the above-described configuration.
Next, the configuration of the bag body 3 will be described. The bag body 3 is an accommodation container that accommodates the wet tissue continuing material body 6 therein. The bag body 3 is formed in, for example, a pillow-like bag shape by a plastic film having air-tightness and flexibility or the like. As illustrated in

For example, the extraction hole forming member 4 is formed of a thermoplastic resin material such as polyethylene and polypropylene. In this embodiment, the description is provided by using the extraction hole forming member 4 which is integrally molded by an injection molding method or the like, but the extraction hole forming member 4 may also be formed by the combination of the separately molded members. Further, the extraction hole forming member 4 may be formed by a method other than the above-described method.
As illustrated in
Further, the extraction hole forming member 4 provided in this example includes a partitioning portion 24 and a fragile portion 25. The partitioning portion 24 is provided or arranged to close the pinching hole 22 and partitions the accommodation space 23 into a plurality of sections. The fragile portion 25 is formed at the peripheral edge portion of the partitioning portion 24 and is broken when a predetermined shear force is applied thereto.
The base plate 21 is formed in a flat square plate shape, and is formed so that the upper surface thereof becomes an attachment surface when the base plate 21 is attached to the inner surface of the bag body 3. The reference numeral 28 of
A vertical wall portion 30 is uprightly formed in the extraction concave portion 29. The vertical wall portion 30 is formed in a circular shape in the top view of the extraction hole forming member 4. Further, the vertical wall portion 30 is formed so that the outer diameter of the vertical wall portion 30 is smaller than the inner diameter of the extraction concave portion 29. Furthermore, the vertical wall portion 30 is formed at a position where the center position of an inner wall 29a of the extraction concave portion 29 coincides with the center position of the vertical wall portion 30. That is, the vertical wall portion 30 is formed so that a circle drawn by the inner wall 29a of the extraction concave portion 29 is concentric with a circle drawn by the vertical wall portion 30. Further, as illustrated in

The accommodation space 23 accommodates the front end 6a of the wet tissue continuing material body 6 through the pinching hole 22 and is a space indicated by the dotted line in
The partitioning portion 24 partitions the bag body 3 into the inside and the outside by closing the pinching hole 22. Further, the partitioning portion 24 also separates the accommodation space 23 into the space that communicates with the inside of the bag body 3 and the space that communicates with the outside of the bag body 3. As illustrated in
The fragile portion 25 is provided in the peripheral edge portion of the partitioning portion 24. As illustrated in
The extraction hole forming portion 27 separates the wet tissue 7 at the separating portion 10 provided in the wet tissue continuing material body 6 and allows the front end 6a of the wet tissue continuing material body 6 to pop up. As illustrated in
As illustrated in
Furthermore, in the extraction hole forming portion 27, a first protruding piece 35 is provided between the extraction hole 26 and the first slit 33, and a second protruding piece 36 is provided between the first slit 33 and the second slit 34. The first protruding piece 35 includes a left protruding piece 35a that extends from the left to the right and a right protruding piece 35b that extends from the right to the left, and a first void 37 is provided between the left protruding piece 35a and the right protruding piece 35b. Further, the second protruding piece 36 includes a left protruding piece 36a that extends from the left to the right and a right protruding piece 36b that extends from the right to the left, and a second void 38 is provided between the left protruding piece 36a and the right protruding piece 36b. The first and second voids 37 and 38 are formed to be located on the substantially same straight line in the right-left direction.
As illustrated in
Furthermore, the extraction hole forming portion 27 of this embodiment is integrally formed with the pair of leg portions 32a and 32b and the base plate 21, but may also be formed separately from the base plate or have the other structures.
The lid 5 is provided on the extraction hole forming member 4 in an openable and closable manner and is configured to close or open the accommodation space 23 provided in the extraction hole forming member 4. Further, the extraction hole forming member 4 and the lid 5 may be molded separately from each other, and may also be molded integrally with each other by a structure other than hinges in a case where they are formed integrally with each other. The lid 5 is formed of the same material as that of the extraction hole forming member 4, for example, a thermoplastic resin material such as polyethylene and polypropylene.

Next, in the wet tissue packaging unit 1 according to this embodiment, a procedure of removing the partitioning portion 24 will be described. In a case where the wet tissue packaging unit 1 according to this embodiment is an unused item that the user does not use yet, as illustrated in
When the user initially uses the wet tissue packaging unit 1, first, the partitioning portion 24 is removed. In the case of removing the partitioning portion 24, the user pinches the tab 31 with a finger and applies a force in the A direction in
When the shear force in the B direction is applied to the fragile portion 25 by the force in the A direction applied by the user, since the fragile portion 25 is formed to be thinner than the partitioning portion 24, a stress applied to the fragile portion 25 becomes greater than a stress applied to positions other than the fragile portion 25. Therefore, the fragile portion 25 is likely to undergo shear failure, and undergoes shear failure when a predetermined stress is applied thereto such that the partitioning portion 24 is removed from the extraction hole forming member 4. The fragile portion 25 gradually undergoes shear failure from the position to which the predetermined shear force is applied and the entire fragile portion 25 finally undergoes shear failure. When the shear failure of the entire fragile portion 25 occurs, as illustrated in
As illustrated in
Next, a procedure of drawing out the wet tissue continuing material body 6 by the user will be described. When the pinching hole 22 is opened in the above-described procedure, the extraction hole forming portion 27 and the extraction hole 26 of the extraction hole forming member disposed inside the bag body 3 are visible through the pinching hole 22 from the outside of the bag body 3. This is because the extraction hole forming member 4 is attached at the position which coincides with the position of the pinching hole 22 in the forward-rearward and right-left directions and the position of the opening 2 of the bag body 3 in the forward-rearward and right-left directions.
As illustrated in
In these cases, the user draws out the front end 6a of the wet tissue continuing material body 6. When the front end 6a is drawn, the user puts a finger into the pinching hole 22 which is opened in the precedent procedure and pushed down the extraction hole forming portion 27 or the like to move the extraction hole forming member 4 (including the upper portion of the bag body 3) in the C direction in
Next, as illustrated in
At this time, the wet tissue continuing material body 6 is drawn out while applying a force in the D direction (
As illustrated in
The wet tissue 7 forming the front end 6a of the wet tissue continuing material body 6 after the separation does not receive the force in the F direction which has been applied by the user in
After extracting the wet tissue 7, the user closes the lid 5 to seal the bag body 3. When the wet tissue 7 is to be extracted thereafter, the user may open the lid 5 again, insert a finger into the pinching hole 22, pinch the front end 6a of the wet tissue continuing material body 6 which has already popped up and draw out the wet tissue continuing material body 6. Then, the wet tissue 7 is separated at the separating portion 10 by the same operation as described above such that the sheet-like wet tissue 7 is drawn out.
When the wet tissue 7 is extracted again, even in a case where the front end 6a of the wet tissue continuing material body 6 has not popped up, the wet tissue 7 may be drawn out in the same order described above.
In the wet tissue packaging unit 1 according to this embodiment, as the wet tissues 7 are drawn out, the volume of the wet tissue continuing material body 6 decreases. However, in the wet tissue packaging unit 1 according to this embodiment, the lid 5 is formed in an openable and closable manner with respect to the extraction hole forming member 4. Therefore, even when the volume of the wet tissue continuing material body 6 accommodated in the bag body 3 decreases, the lid 5 may be closed to seal the bag body 3. Therefore, according to the wet tissue packaging unit 1 according to this embodiment, the bag body 3 is prevented from not being maintained in the sealed state and thus the chemical solution and the like impregnated into the wet tissue continuing material body 6 (the wet tissue 7) are prevented from volatilizing. Accordingly, it is possible to provide the wet tissue 7 in a state where the chemical solution and the like are always impregnated therein for the user.
Further, according to the wet tissue packaging unit 1 according to this embodiment, in the case where the wet tissue packaging unit 1 is the unused item, the pinching hole 22 is closed by the partitioning portion 24. To use the wet tissue packaging unit 1, the fragile portion 25 provided in the peripheral edge portion of the partitioning portion 24 is broken to remove the partitioning portion 24 and open the pinching hole 22, and thereafter the front end 6a of the wet tissue continuing material body 6 is pinched. Accordingly, it is possible to very easily determine whether or not the wet tissue packaging unit 1 is the unused item according to the presence or absence of the partitioning portion 24. Therefore, when using the wet tissue packaging unit 1 or purchasing the wet tissue packaging unit 1, it is possible for the user to use or purchase the wet tissue packaging unit 1 after determining whether or not the wet tissue packaging unit 1 is the unused item.
Furthermore, according to the wet tissue packaging unit 1 according to this embodiment, since the extraction hole forming member 4 provided with the lid 5 is attached to the inner surface of the bag body 3, during the manufacture, it is possible to manufacture the wet tissue packaging unit 1 without a process of attaching the lid 5 after attaching the extraction hole forming member 4 to the bag body 3. Therefore, according to the wet tissue packaging unit 1 according to this embodiment, the number of processes may be reduced during the manufacture and hence it is possible to largely reduce the manufacturing cost. Furthermore, the wet tissue packaging unit 1 according to this embodiment includes the relief portion which allows the accommodation space 23 and the internal space of the bag body 3 to communicate with each other. Accordingly, when the front end 6a of the wet tissue continuing material body 6 is to be accommodated in the accommodation space 23, in a case where the front end 6a is not entirely accommodated only in the accommodation space 23, a portion of the front end 6a may be relieved to the inside of the bag body 3 through the relief portion. Therefore, according to the wet tissue packaging unit 1 according to this embodiment, the bag body 3 may be always sealed by closing the lid 5 regardless of the pop-up amount of the front end 6a of the wet tissue continuing material body 6, and hence it is possible to prevent the chemical solution and the like impregnated into the wet tissue continuing material body 6 (the wet tissue 7) from volatilizing.
Next, a second embodiment of the wet tissue packaging unit according to the present invention will be described with reference to
The wet tissue packaging unit according to this embodiment is different from that of the first embodiment described above in the structure of the extraction hole forming member, and hence the structure of the extraction hole forming member will now be described.
An extraction hole forming member 51 according to this embodiment is attached at a position where the positions of an extraction hole 54 and the opening 2 of the bag body 3 coincide with each other on the inner side of the bag body 3. As a method of attaching the extraction hole forming member 51 to the bag body 3, for example, a method using hot-melt or the like may be exemplified, but the present invention is not limited thereto. That is, various methods may be arbitrarily selected.
For example, the extraction hole forming member 51 may be formed of a thermoplastic resin material such as polyethylene and polypropylene. In this embodiment, the description is provided by using the extraction hole forming member 51 which is integrally molded by an injection molding method or the like, but the extraction hole forming member 51 may also be formed by the combination of the separately molded members. Further, the extraction hole forming member 51 may be formed by a method other than the above-described method.
As illustrated in
The base plate 52 is formed in a flat square plate shape, and is formed so that the upper surface thereof becomes an attachment surface when the base plate 52 is attached to the inner surface of the bag body. The reference numeral 57 of
A vertical wall portion 59 is uprightly formed in the extraction concave portion 58. The vertical wall portion 59 is formed in a circular shape in the top view of the extraction hole forming member 51. Further, the vertical wall portion 59 is formed so that the outer diameter of the vertical wall portion 59 is smaller than the inner diameter of the extraction concave portion 58. Furthermore, the vertical wall portion 59 is formed at a position where the center position of an inner wall of the extraction concave portion 58 coincides with the center position of the vertical wall portion 59. That is, the vertical wall portion 59 is formed so that a circle drawn by the inner wall of the extraction concave portion 58 is concentric with a circle drawn by the vertical wall portion 59. Further, the vertical wall portion 59 is formed so that the position of the upper surface thereof in the height direction is lower than the position of the upper surface of the base plate 52 in the height direction and when the lid 5 is closed, the upper surface of the lid 5 and the upper surface of the base plate 52 substantially are flush with each other.
The accommodation space 53 is a space formed to accommodate the front end 6a of the wet tissue continuing material body 6. The accommodation space 53 is sealed when the lid 5 is closed. The accommodation space 53 is surrounded by the lid 5, the closing portion 55, and the vertical wall portion 59 when the wet tissue packaging unit 1 is the unused item and the lid 5 is closed. Further, when the lid 5 is closed in a case of a used item in which the closing portion 55 is formerly removed, the accommodation space 53 is formed to be surrounded by the lid 5 and the vertical wall portion 59 and to communicate with the internal space of the bag body 3 through the extraction hole 54.
The extraction hole 54 is formed such that the wet tissue 7 separates at the separating portion 10 provided in the wet tissue continuing material body 6 and the following front end 6a of the wet tissue continuing material body 6 is allowed to pop up. As illustrated in
As illustrated in
The closing portion 55 partitions the bag body 3 into the inside and the outside by closing the extraction hole 54. The closing portion 55 is formed inside the vertical wall portion 59. Further, a tab 60 is integrally formed with the upper portion of the closing portion 55. The tab 60 is formed in an annular shape and is formed so that a part of the inner portion thereof is connected to the closing portion 55.
The fragile portion 56 is provided in the peripheral edge portion of the closing portion 55. As illustrated in
Next, the operation/working-effect of the wet tissue packaging unit according to this embodiment when the front end 6a of the wet tissue continuing material body 6 is extracted therefrom will be described. Further, in this embodiment, the procedure of removing the closing portion 55 and the procedure of extracting the wet tissue 7 by drawing out the front end 6a of the wet tissue continuing material body 6 after removing the closing portion 55 are the same as those of the first embodiment, and hence the description thereof will not be repeated.
As illustrated in
Here, since the first and second extraction slits 62 and 63 are formed while drawing the curves as described above, a resistance is applied to the wet tissue continuing material body 6 in the forward-rearward and right-left directions when the wet tissue continuing material body 6 passes through the first and second extraction slits 62 and 63. The resistance is applied in the opposite direction to the direction in which the user draws out the front end 6a of the wet tissue continuing material body 6. Therefore, when the separating portion 10 of the wet tissue continuing material body 6 passes through the extraction hole 54, the wet tissue continuing material body 6 is separated at the separating portion 10 and the sheet-like wet tissue 7 is extracted.
At this time, in the wet tissue continuing material body 6, the front end 6a pops up to the upper portion of the extraction hole 54 and thus tries to move downward. However, even in this case, a resistance is applied to the wet tissue continuing material body 6 by the pinching hole 61 and the first and second extraction slits 62 and 63. The resistance in this case is applied in the opposite direction to the direction in which the front end 6a of the wet tissue continuing material body 6 tries to move downward, and the magnitude of the force balances with the force applied when the front end 6a tries to move. Therefore, the front end 6a of the wet tissue continuing material body 6 does not move downward due to the extraction hole 54 and is maintained in the state of popping up to the upper portion of the extraction hole 54, that is, in the pop-up state. At this time, the front end 6a is accommodated in the accommodation space 53. When the user closes the lid 5, the accommodation space 53 is sealed and hence the wet state of the wet tissue continuing material body 6 accommodated in the accommodation space 53 and the bag body 3 is maintained.
As described above, according to the wet tissue packaging unit according to this embodiment, since the extraction hole 54 is provided in the extraction hole forming member 51 and the pinching hole 61 and the first and second extraction slits 62 and 63 are provided in the extraction hole 51, it is possible to easily extract the wet tissue 7 without complicating the shape of the extraction hole forming member 51. Further, according to the wet tissue packaging unit according to this embodiment, since the lid 5 is provided in the extraction hole forming member 51, even when the volume of the wet tissue continuing material body 6 decreases, the bag body 3 may be sealed only by closing the lid 5. Therefore, it is possible to maintain the wet tissue continuing material body 6 accommodated in the bag body 3 in a wet state and thus it is possible to provide the wet tissue 7 in a state where the chemical solution and the like are always impregnated therein for the user.
Furthermore, according to the wet tissue packaging unit according to this embodiment, in the case where the wet tissue packaging unit is the unused item, the extraction hole 54 is closed by the closing portion 55. To use the wet tissue packaging unit, the fragile portion 56 provided in the peripheral edge portion of the closing portion 55 is broken to remove the closing portion 55 and to open the extraction hole 54, and thereafter the front end 6a of the wet tissue continuing material body 6 is pinched. Accordingly, it is possible to very easily determine whether or not the wet tissue packaging unit is the unused item according to the presence or absence of the extraction hole 54. Therefore, it is possible for the user to use the wet tissue packaging unit and to purchase the wet tissue packaging unit after determining whether or not the wet tissue packaging unit is the unused item.
Furthermore, according to the wet tissue packaging unit according to this embodiment, since the extraction hole forming member 51 provided with the lid 5 is attached to the inner surface of the bag body 3, during the manufacture, it is possible to manufacture the wet tissue packaging unit without a process of attaching the lid 5 after attaching the extraction hole forming member 51 to the bag body 3. Therefore, according to the wet tissue packaging unit according to this embodiment, the number of processes may be reduced during the manufacture and hence it is possible to largely reduce the manufacturing cost.
Next, a wet tissue packaging unit according to a third embodiment of the present invention will be described with reference to
The wet tissue packaging unit according to this embodiment is different from those of the first and second embodiments described above in the structure of an extraction hole forming member 71, and hence the structure of the extraction hole forming member 71 will now be described.
The extraction hole forming member 71 according to this embodiment is attached at a position where the positions of an extraction hole 77 to be described later and the opening 2 of the bag body 3 coincide with each other on the inner side of the bag body 3. As a method of attaching the extraction hole forming member 71 to the bag body 3, for example, a method using hot-melt or the like may be exemplified, but the present invention is not limited thereto. That is, various methods may be arbitrarily selected.
