DESCRIPTION OF THE EMBODIMENTS

(8) A description will be given of an embodiment of the present invention with reference to the drawings.

(9) FIGS. 1 to 6 show a wet wipe packaging body according to an embodiment of the present invention.

(10) FIG. 1 is an external perspective view of a wet wipe packaging body 1 that is in use. A bag body 3 having an opening portion 2 at the central area of its one surface is sealed at its open area other than the opening portion 2 by heat sealing or the like using a flexible plastic film or the like having air-tightness and is formed into, for example, a pillow-like bag shape. The bag body 3 may be made of a plastic film or the like having a single-layered structure but may be made of a layered film or the like having a plurality of layers. In the bag body 3, a wet wipe stacked body 6b is accommodated (FIG. 2).

(11) The opening portion 2 is formed to be opened at the central area of one of the largest surfaces of the bag body 3 to outwardly pull a tip end portion 6a of a wet wipe continuous body 6. A ring-shaped outlet port frame body 4 made of a plastic material or the like having rigidity is attached to the opening portion 2. Further, a cover body 5 with which the opening portion 2 is openable and closeable from an outside is openably and closably connected to the outlet port frame body 4. The cover body 5 is, when being closed, fitted over the circumference of a ring-shaped outer circumferential portion 4a of the outlet port frame body 4 to close an outlet port formed on the inner side of the outer circumferential portion 4a of the outlet port frame body 4. The outlet port frame body 4 and the cover body 5 are integrally molded with each other by, for example, a thermoplastic resin such as polyethylene and polypropylene via a hinge portion 5a serving as a shaft for rotational movements. However, the outlet port frame body 4 and the cover body 5 may be configured to be formed as separate bodies and combined with each other.

(12) The outlet port frame body 4 of the embodiment is formed into, for example, a ring shape such as a circular or elliptical shape. However, other ring shapes may be used. Further, a flange-shaped portion 4b is formed to project from the circumference of the bottom portion, and the lower surface side of the flange-shaped portion 4b of the outlet port member 4 is air-tightly bonded by a hot melt adhesive or other adhesives to the outer front surface of the bag body 3 so as to surround the periphery of the opening portion 2 at a position away from the outer circumference of the opening portion 2.

(13) FIG. 2 is a vertical cross-sectional view of the lateral surface side of the wet wipe packaging body. The wet wipe stacked body 6b accommodated in the bag body 3 is one obtained by folding the wet wipe continuous body 6 in which adjacent wet wipes as a plurality of independent sheet wet wipes are overlapped with each other at their ends, and is folded and stacked together by so-called Z-folding, W-folding, WZ-folding, or the like.

(14) Thus, when the tip end portion 6a of the wet wipe continuous body 6 is outwardly pulled out from the opening portion 2, the rear end of the pulled-out wet wipe continuous body 6 is not brought into contact with the tip end of the wet wipe continuous body 6 stacked in the next place, whereby a single wet wipe is separated from the wet wipe continuous body 6.

(15) The wet wipe continuous body 6 is base cloth impregnated with a medicine or the like. A paper, woven cloth, non-woven cloth, or the like made of, for example, synthetic fibers or natural fibers is used as a base cloth material, but the wet wipe continuous body 6 may be made of other materials. Further, examples of a medical solution or the like include an alcohol, water, or their mixtures. However, a perfume, an antibacterial agent, a deodorizing agent, a surfactant, an antiseptic, a pigment, a defoaming agent, an antioxidant, a clarifier, a solubilizing agent, or the like may be blended together, or other medical solutions or the like may be used.

(16) As described above, the cover body 5 is rotatably connected about the hinge portion 5a to the outlet port frame body 4 adhered to the outer front surface of the bag body 3 so as to surround the opening portion 2 of the bag body 3. FIG. 2 shows a state, in which the cover body 5 is closed to close the outlet port frame body 4, by solid lines and shows a state, in which the cover body 5 is opened, by chain double-dashed lines.

(17) The opening portion 2 of the bag body 3 is tightly closed by a flap seal 20 bonded to the outer surface of the bag body 3. As specifically shown in FIG. 3 that is an exploded perspective view of the wet wipe packaging body 1, the flap seal 20 is configured to be folded in two by a folding back portion 21 and doubly overlapped with each other in a vertical direction. A sealing surface 22 on the lower side of the flap seal 20 is formed to have a size at which the entire opening portion 2 can be tightly closed, a picking-up piece 23 on the upper side is formed to be narrower than the sealing surface 22 and configured as a picking-up portion to peel the sealing surface 22. Further, an end 24 of the picking-up piece 23 at a position away from the folding back portion 21 is formed to slightly project outward from the outer circumference of the sealing surface 22 so as to be easily picked up by fingers.

(18) The lower surface (rear surface) of the sealing surface 22 of the flap seal 20 thus configured is bonded to the front surface of the bag body 3, and the opening portion 2 of the wet wipe packaging body that is not in use is tightly closed by the flap seal 20 as shown in FIG. 2. This results in advantages such as preventing the drying of the wet wipe stacked body 6b in the bag body 3 even in a case in which the wet wipe packaging body is preserved for a long time and making an adhesive that bonds the outlet port frame body 4 to the bag body 3 be free from the adverse effect of vapors of medicine or the like generated by the wet wipe stacked body 6b. Note that the flap seal 20 is not necessarily the one in which the sealing surface 22 and the picking-up piece 23 are integrally formed with each other as described in the embodiment. For example, the flap seal 20 may have a configuration in which a sealing surface and a picking-up piece as separate bodies are joined together by the folding back portion 21, or the like.

(19) In the inner region of the outlet port frame body 4, a resistance application member 9 having a resistance application hole 8 for applying resistance to the passing-through wet wipe continuous body 6 is arranged (FIGS. 1 and 3). The resistance application hole 8 is well known. When the wet wipe continuous body 6 is pulled outwardly from the bag body 3, frictional resistance is applied to the wet wipe continuous body 6, which passes through the inner side of the resistance application hole 8, from the resistance application hole 8. Thus, the wet wipe continuous body 6 is separated at its separation allowing portion at a position at which the wet wipe continuous body 6 has just passed through the resistance application hole 8, and the wet wipe continuous body 6, which is positioned ahead of the separation allowing portion and covers its area from a tip end portion 6a to the separation allowing portion, is taken out as a single wet wipe. Then, the outermost tip end portion of the wet wipe continuous body 6 left behind the taken-out wet wipe is held in a state of slightly outwardly projecting from the resistance application hole 8. Note that the resistance application hole 8 has various known shapes and may employ any of the shapes. Further, the resistance application hole 8 may have any shape other than the known ones so long as resistance, by which a single wet wipe can be separated from the wet wipe continuous body 6 and the tip end portion of the wet wipe continuous body 6 in the next place can be held, can be applied to the wet wipe continuous body.

(20) The resistance application member 9 having the resistance application hole 8 as described above is formed to be integrated with or separated from the outlet port frame body 4 and brought into a so-called cantilevered state in which only one end side of the resistance application member 9 is fixed to the outlet port frame body 4. Further, the side of a free end 9a of the resistance application member 9 is biased so as to enter the bag body 3 via the opening portion 2. In the embodiment, the resistance application member 9 has a biasing force generated from its own elasticity. However, an elastic member or the like for applying a biasing force to the resistance application member 9 may be separately provided.

(21) With the configuration described above, provided that the flap seal 20 has been removed as shown in FIG. 1, the side of the free end 9a of the resistance application member 9 moves downward from a position indicated by the chain double-dashed lines to a position indicated by dashed lines in the bag body 3 due to the biasing force, in accordance with the reduction amount of the bulk of the wet wipe stacked body 6b, as shown in FIG. 2. Therefore, even if the bulk of the wet wipe stacked body 6b is reduced, the resistance application member 9 is continuously pressed against the front surface of the wet wipe stacked body 6b. Note that FIG. 2 shows a state in which the flap seal 20 has not been removed, but the above description on the movements of the resistance application member 9 is given assuming that the flap seal 20 has been removed.

(22) In the way described above, the resistance application member 9 is tilted relative to the pulling-out direction of the wet wipe continuous body 6 in a state in which the bulk of the wet wipe stacked body 6b is reduced. As a result, strong frictional resistance is applied to the wet wipe continuous body 6 from the resistance application hole 8, whereby a leading wet wipe of the wet wipe continuous body 6 can be separated and pulled out at an appropriate position.

(23) As shown in, for example, FIG. 3, the resistance application member 9 described above is integrally molded with the outlet port frame body 4 in a state of projecting from the outlet port frame body 4 in a direction opposite to the cover body 5 by 180 degrees. However, the resistance application member 9 may be made of a member different from the outlet port frame body 4 and attached to the outlet port frame body 4 by a method such as engagement. The cover body 5 is rotated in a direction indicated by an arrow A in FIG. 3 and used so as to make the outlet port of the outlet port forming member 4 openable and closeable. On the other hand, the resistance application member 9 is rotated in a direction indicated by an arrow B to fold a joining portion 9b between the resistance application member 9 and the outlet port frame body 4 and arranged from the side of the bottom portion of the outlet port frame body 4 so as to be positioned on the inner side (taking-out side) of the outlet port frame body 4. As a result, the biasing force is generated in the resistance application member 9 in a direction opposite to the arrow B.

(24) Accordingly, when the outlet port frame body 4 is attached to the bag body 3 to be assembled for manufacturing, there is a likelihood that the resistance application member 9 pops up from the outlet port frame body 4 to cause a difficulty in smoothly assembling the outlet port frame body 4. Therefore, in the embodiment, short pin-shaped holding bodies 11 capable of freely engaging with the resistance application member 9 and holding the resistance application member 9 in a region inside the outlet port frame body 4 are provided projectingly from the rear surface of the cover body 5, and engagement holes 12 in which the holding bodies 11 are elastically fitted are provided on the side of the resistance application member 9 to solve the above problem. The holding bodies 11 can be integrally molded with the cover body 5. In addition, the engagement force of the holding bodies 11 to the engagement holes 12 is further secured if the head portions of the holding bodies 11 are slotted.

(25) As shown in FIG. 2, when the holding bodies 11 projecting from the cover body 5 are fitted in the engagement holes 12 formed in the resistance application member 9, the resistance application member 9 is attracted to the vicinity of the cover body 5 and held by the cover body 5. With the configuration described above, hindrance in the adhering operation of the outlet port frame body 4 due to the downwardly-projecting resistance application member 9 is prevented when the outlet port frame body 4 is adhered to the bag body 3, and thus the attachment can be smoothly performed. The state remains until the cover body 5 is first opened after the manufacturing of the wet wipe packaging body 1. Then, once the cover body 5 is opened, the holding bodies 11 are disengaged from the engagement holes 12 to release a state in which the resistance application member 9 is held by the holding bodies 11.

(26) FIG. 4 shows a state of the inner side of the outlet port frame body 4 when the cover body 5 is opened after the outlet port frame body 4 is attached to the outer surface side of the bag body 3 of which the opening portion 2 is tightly closed by the flap seal 20. Since the state in which the resistance application member 9 is held by the holding bodies 11 is released at this time, the resistance application member 9 is pressed against the side of the flap seal 20 by the biasing force. Therefore, in order to peel the flap seal 20 to be ready for the use of the wet wipes, the side of the free end 9a of the resistance application member 9 is lifted upward, the end 24 of the picking-up piece 23 of the flap seal 2Q is picked up and pulled by fingers to peel the sealing surface 22 from the bag body 3, and the flap seal 20 is removed from the inner side of the outlet port frame body 4 as shown in FIG. 5. In this way, the wet wipe packaging body 1 can be put into the state ready for the use of the wet wipes shown in FIG. 1. FIG. 6 shows the state of the resistance application member 9 when seen from the inner side of the bag body 3 at this time. Here, the side of the free end 9a of the resistance application member 9 biased toward the inner side of the bag body 3 (in a direction indicated by an arrow C) enters the bag body 3 via the opening portion 2 and is pressed against the front surface of the wet wipe stacked body 6b not shown.

(27) Note that the holding bodies 11 are not necessarily the short pin-shaped members formed to project from the rear side of the cover body 5 so long as they are structured to be capable of holding the resistance application member 9, but the holding bodies 11 may have any shape and structure so long as they can appropriately hold the resistance application member 9 on the inner side of the outlet port frame body 4. In addition, the holding bodies 11 are not limited to those configured to be disengaged from the engagement holes 12 of the resistance application member 9 when the cover body 5 is opened, but the holding bodies 11 may be those configured to be disengaged from the resistance application member 9 by hand after the cover body 5 is opened. Moreover, the holding bodies 11 are not limited to those provided on the rear surface side of the cover body 5 but may be those provided on the outlet port frame body 4 or the like.

(28) The above embodiment shows an example in which the opening portion 2 of the bag body 3 is configured to be tightly closed by the flap seal 20 and the flap seal 20 is peeled in use. However, the opening portion 2 may be configured to be tightly closed by a seal in a half-cut state and opened by pressing or peeling a half-cut portion to or from the bag body 3 for use. Further, the opening portion 2 can also be configured such that the outlet port of the outlet port frame body 4 is tightly closed by a pull-top cover instead of the flap seal and the pull-top cover is pulled out to open the opening portion 2 in use.

(29) Further, the above embodiment shows a case in which the one end side of the resistance application member 9 is fixed to the outlet port frame body 4 to bring the resistance application member 9 into a cantilevered state. However, as shown in FIGS. 7A to 7D, the resistance application member 9 may be brought into a so-called both-end support state in which the both ends of the resistance application member 9 are fixed to the outlet port frame body 4. As shown in, for example, FIG. 7A, the both ends of the resistance application member 9 may be attached to a pleated portion 25 fixed to the outlet port frame body 4 such that the resistance application member 9 is biased by the restoration force of the compressed pleated portion 25. Further, as shown in FIG. 7B, the both ends of the resistance application member 9 may be respectively fixed to the first ends of springs 26, second ends of which are fixed to the outlet port frame body 4, such that the resistance application member 9 is biased by the restoration force of the compressed springs 26. Further, as shown in FIG. 7C, the resistance application member 9 may be fixed to elastic bodies 27 instead of springs such that the resistance application member 9 is biased by the restoration force of the elastic bodies 27 compressed so as to curve. Further, as shown in FIG. 7D, rod-shaped supporting bodies 28 made of elastic bodies or the like may be attached to the outlet port frame body 4 at their folded ends on one side and fixed to the resistance application member 9 at their ends on the other side such that the resistance application member 9 is biased by a restoration force generated when the compressed folded portions 28a are compressed. Examples of the above elastic bodies include, but not limited to, rubber, plastic, or the like so long as they are made of materials having elasticity. However, rubber and plastic are generally preferable. Note that in a case in which the resistance application member 9 is brought into a both-end support state as shown in FIGS. 7A to 7D, the opening portion 2 of the bag body 3 is preferably configured to be tightly closed by a seal in a half-cut state and opened by pressing a half-cut portion into the bag body 3, or the opening portion 2 is preferably configured such that the outlet port of the outlet port frame body 4 is tightly closed by a pull-top cover and the pull-top cover is pulled out to open the opening portion 2.

(30) The present invention is not limited to the above embodiment but includes all modes in the concepts of the inventions of the claims.
