A plurality are arranged at equal intervals. For example, two engagement means 9 are arranged on one side of the hinge 11 on both sides of the hinge 11, and three engagement means 9 are arranged on the other side edge opposite to the hinge 11 at substantially equal intervals. Further, two engaging means 9 are arranged on the other two side edges at substantially the same interval as one side of the hinge 11 side. In the case where the outer peripheral edge 19 of the container 6 and the lid mounting frame 10 have sufficient rigidity so that no gap or the like is generated between them, at least one side edge of the hinge 11 side It may be provided on the other side edge opposite to the hinge 11.

  As shown in FIGS. 5 and 7, each of the engagement means 9 includes an engagement portion 34 provided on the attachment portion 33 of the lid attachment frame 10 and an engaged portion provided on the outer peripheral edge 19 of the container 6. 35. The mounting portion 33 of the lid mounting frame 10 is provided with a protruding portion 36 protruding inward corresponding to each engaging means 9.

  As shown in FIGS. 5 and 7, the projecting portion 36 has a horizontally long shape that is long in the longitudinal direction of the side of the mounting portion 33, and the upper side of the projecting portion 36 becomes the steeply engaging portion 34. An inclined guide portion 37 which is gently inclined is formed below the lower side 34, and a concave portion 38 corresponding to the projecting portion 36 is formed outside. The inclined guide portion 37 guides the engaged portion 35 slidably when the engagement means 9 is engaged.

  In the protruding portion 36, the upper engaging portion 34 has a steeply inclined shape, and the lower portion has the inclined guide portion 37 which is gently inclined in the opposite direction, so that the maximum protruding portion (the maximum recessed portion of the concave portion 38) is formed. It is deviated upward from the center of the vertical width.

  When the engaging portion 34 is engaged with the engaged portion 35, each of the engaging means 9 causes the lid receiving portion 32 to move around the outer periphery of the sealing material 8 by elastic deformation of the protruding edge 21 of the outer peripheral edge portion 19. Alternatively, the lid mounting frame 10 may be urged downward so as to press on the part.

  As shown in FIGS. 5 and 6, the opening / closing lid 12 is close to or in contact with the lid receiving portion 32 of the lid mounting frame 10 in the closed state to close the opening 31, and an outer periphery of the lid 39. And a peripheral wall portion 40 that is formed to be bent downward from above and that fits on the outer periphery of the attachment portion 33 of the lid attachment frame 10.

  As shown in FIG. 1 and FIG. 4, the hinge 11 has a length of approximately half of the side of the mounting portion 33 of the lid mounting frame 10 and one side of the peripheral wall portion 40 of the opening / closing lid 12, that is, approximately less than half. The mounting portion 33 of the lid mounting frame 10 and the peripheral wall portion 40 of the opening / closing lid 12 are disposed substantially at the center in the longitudinal direction of one side.

  As shown in FIGS. 6 and 8, the hinge 11 is shaped like a letter when viewed from the side, and the lower end, which is one end, is on the lower peripheral edge 41 of the mounting portion 33 of the lid mounting frame 10, and the upper end, which is the other end, is A bent portion 43 that is connected to the lower end outer peripheral edge 42 of the peripheral wall portion 40 of the opening / closing lid 12 and that is bent upward and downward to bend outward and outward so as to be able to bend and extend is provided.

  The bent portion 43 is formed by cutting the cut portion 45 from the outside of the bent portion 43 so that the uncut portion 44 can be intermittently formed in the longitudinal direction inside the bent portion 43. The opening and closing of the opening and closing lid 12 is allowed by the bending and stretching movement, and when the opening and closing lid 12 is opened to an open position O (see FIGS. 1 and 8) at an obtuse angle with respect to the lid receiving portion 32 of the lid mounting frame 10, a notch is formed. The opposing ends of the portion 45 are in contact with each other to hold the opening / closing lid 12 at the open position O.

  It is desirable that the hinge 11 be held at an open position O where the opening / closing lid 12 is opened at an obtuse angle with respect to the lid mounting frame 10. However, the open position O may be set to a position where the opening / closing lid 12 is opened by 180 degrees or more with respect to the lid mounting frame 10. The bent portion 43 may be a perforation or the like in which the penetrating portions are formed at substantially equal intervals, or may be formed so that the uncut portion 44 and the cut portion 45 are linearly continuous in and out. The bent portion 43 may have a bent shape that is simply bent in a V shape.

  As shown in FIGS. 5 and 7, the locking means 13 is provided on the opposite side of the hinge 11 so as to correspond to the central engaging means 9, and the peripheral wall 40 of the opening / closing lid 12 is attached to the lid mounting frame. When it is fitted and closed on the outer periphery of the mounting portion 33, the opening / closing lid 12 is locked in a closed state. The locking means 13 includes a locking portion 47 formed to project inward from the peripheral wall portion 40 of the opening / closing lid 12, and a locked portion provided above the concave portion 38 of the mounting portion 33 of the lid mounting frame 10. And the locking portion 47 engages with the locked portion 48 when the opening / closing lid 12 is closed.

  The concave portion 38 on the outer peripheral side of the attaching portion 33 of the lid attaching frame 10 is for the engaging means 9 at the center of the other side edge opposite to the hinge 11. Therefore, the locking means 13 is disposed substantially at the center of the other side edge opposite to the hinge 11. The lower end of the peripheral wall 40 of the opening / closing lid 12 is a finger hook 49.

  The band sealing material 14 is formed by wrapping a band-shaped sheet of a predetermined width around the outer periphery of the container 6 and the opening / closing lid 12 and overlapping the ends 14a and 14b with each other and stopping at the stopper 14c. If the part 14b is pulled and the stopper part 14c is peeled off, it will come off easily. The band sealing material 14 may be wound in a direction intersecting with the longitudinal direction of the hinge 11 or may be wound along the longitudinal direction of the hinge 11.

  A decorative material 51 such as a shrink film is closely wound around the outer periphery of the peripheral wall portion 40 of the container 6. A rectangular or other decorative material 52 is attached to the upper surface of the opening / closing lid 12. The band seal material 14 and the decorative materials 51 and 52 display a trademark and other necessary information on the wet material 2 by printing or the like.

  When manufacturing the wet material package 1 in which the laminate 3 of the wet material 2 is packed in the packaging container 5, the laminate 3 of the wet material 2 and the impregnating liquid 4 are put into the container 6, and then the container 6 is The sealing material 8 is fixed to the outer peripheral edge 19, and the opening 7 side is sealed by the sealing material 8. Next, after attaching the lid attaching frame 10 to the upper end side of the container 6 and attaching the opening / closing lid 12 via the lid attaching frame 10, the band sealing material 14 is wound around the container 6 with the opening / closing lid 12 as shown in FIG. And finishing as shown in FIG.

  By using the packaging container 5 having such a simple structure, a conventional outer bag, a shaping member, and the like are unnecessary, and useless materials can be prevented, and automation of the manufacturing process can be easily promoted. And the manufacturing cost can be reduced.

  In addition, the lid attachment frame 10 may be attached to the outer periphery of the outer peripheral edge 19 of the container 6 by fitting the attachment portion 33 from the upper side, so that the lid attachment frame 10 can be easily attached to the upper end side of the container 6. Moreover, between the lid mounting frame 10 and the container 6, a large number of engaging means 9 are provided on the entire circumference in the circumferential direction, and when the mounting portion 33 is fitted to the outer peripheral edge 19, Since the engaging portion 34 of the engaging means 9 engages with the engaged portion 35, the lid mounting frame 10 can be securely fixed to the upper side of the container 6 by each engaging means 9.

  When the engaging portion 34 of the engaging means 9 is engaged with the engaged portion 35, the lid mounting frame 10 is urged toward the container 6 by the elastic force of the outer peripheral edge portion 19 and the like. This makes it possible to prevent rattling of the lid mounting frame 10 and the like.

  When the packaging container 5 is opened, first, the band sealing material 14 is removed, the locking of the opening / closing lid 12 to the lid mounting frame 10 by the locking means 13 is released, and the opening / closing lid 12 is shown around the hinge 11 in FIG. By pivoting to the open position O, the open / close lid 12 can be held at the open position O by the hinge 11.

  Next, a take-out port 24 is formed in the sealing material 8 and opened. At the time of this opening, a finger is inserted through the opening 31 of the lid attachment frame 10 to grip the knob 29 of the release material 26 on the sealing material 8, and the knob 29 is pulled in the direction of peeling the release material 26. . Then, the opening / closing lid 12 is held in an open state at an open position O opened at an obtuse angle with respect to the lid mounting frame 10, and is located at a position separated from above the lid receiving portion 32 including the opening 31 of the lid mounting frame 10. Therefore, it is not necessary to hold the opening / closing lid 12 in an open state with one hand even at the time of opening when the takeout opening 24 is formed in the sealing material 8, and the opening operation can be performed easily and simply.

  When the gripping portion 29 is pinched and the peeling material 26 is pulled in the peeling direction, the sealing material 8 is cut off along the cutoff line 25 and separated into the outlet opening forming region 23 and the outer portion thereof. The sealing material 8 can be removed together with the release material 26 while being adhered to the release material 26. As a result, as shown in FIG. 8, an outlet 24 having a size corresponding to the outlet forming region 23 can be formed in the sealing material 8.

  When removing the wet material 2 from the container 6, fingers are inserted into the container 6 from the opening 31 of the lid receiving portion 32 of the lid attachment frame 10 through the opening 24 of the sealing material 8, and The upper wet material 2 is picked and taken out. Also in this case, since the opening / closing lid 12 is held at the open position O, it is not necessary to hold the opening / closing lid 12 with the other hand at the time of opening, and the opening / closing lid 12 becomes a hindrance when taking out the wet material 2. Without this, the work of taking out the wet material 2 can be performed easily and simply.

  After the wet material 2 is taken out, the opening / closing lid 12 is rotated in the closing direction about the hinge 11 onto the lid mounting frame 10 so that the peripheral wall portion 40 of the opening / closing lid 12 is attached to the outer periphery of the mounting portion 33 of the lid mounting frame 10. The opening 6 side of the container 6 is closed by fitting, and the opening / closing lid 12 is locked by the locking means 13 to the lid mounting frame 10 in the closed state. Thereby, the opening 7 side of the container 6 after removing the wet material 2 can be closed in a substantially sealed state or a state close thereto, and the opening and closing lid 12 can be prevented from being opened unstably.

  That is, the lid mounting frame 10 has its mounting portion 33 fitted in a substantially sealed manner with the outer peripheral edge 19 of the container 6, and the opening / closing lid 12 has its peripheral wall portion 40 attached to the mounting portion 33 of the lid mounting frame 10. Therefore, if the opening / closing lid 12 is closed in a closed state after the wet material 2 is taken out, the opening 7 side of the container 6 can be substantially sealed or sealed.

  Therefore, even after the opening 24 is formed in the sealing material 8 and the packaging container 5 is once opened, by closing the opening / closing lid 12, drying of the wet material 2 and evaporation of the impregnating liquid 4 are prevented beforehand. The wet state required for using the wet material 2 can be maintained until all the wet material 2 has been consumed.

  A locking means 13 is provided on the opposite side of the hinge 11 and the locking means 13 locks the opening / closing lid 12 to the lid mounting frame 10 in a closed state. The closed state of the open / close lid 12 can be maintained continuously without the unstable opening of the lid 12. Therefore, there is no fear that the opening / closing lid 12 is unexpectedly opened and the wet material 2 dries.

  Since the lid mounting frame 10 and the opening / closing lid 12 are integrated via the hinge 11, and are integrally formed by thermoforming the sheet material, the lid mounting frame 10 and the opening / closing lid 12 can be easily and inexpensively formed with a simple structure. Can be manufactured.

  9 and 10 illustrate a second embodiment of the present invention. In the packaging container 5 of this embodiment, a locking means 13a is provided on one side of the hinge 11 between the lid mounting frame 10 and the opening / closing lid 12 so as to face the locking means 13 on the opposite side. The locking means 13a corresponding to the hinge 11 is substantially similar in structure to the locking means 13 on the opposite side, and includes a locked part 48a on the lid mounting frame 10 side and a locking part 47a on the opening / closing lid 12 side. The locking portion 47a and the locked portion 48a are configured to engage and disengage around the bent portion 43 of the hinge 11. Other configurations are the same as those of the first embodiment.

  For example, when the hinge 11 having a bent portion 43 having a bent portion 43 at substantially the center is adopted, if the bent portion 43 of the hinge 11 is not bent well when the opening / closing lid 12 is closed, the hinge 11 is opened and closed. It is conceivable that a gap is formed between the lid 39 of the opening / closing lid 12 and the lid receiving part 32 of the lid mounting frame 10 by pushing up the end of the lid 12.

  However, by providing the locking means 13a on the hinge 11 side between the lid mounting frame 10 and the opening / closing lid 12, the lifting of the opening / closing lid 12 from the lid mounting frame 10 on the hinge 11 side can be prevented. Therefore, the upper and lower gaps between the lid attachment frame 10 and the opening / closing lid 12 can be reduced to ensure the sealing performance.

  FIG. 11 illustrates a third embodiment of the present invention. In the packaging container 5 of this embodiment, as a hinge 11 for connecting the lid mounting frame 10 and the opening / closing lid 12, as shown in FIG. The one provided with the bent portions 43 at two places, that is, the vicinity thereof, is employed. The connecting portion 55 is vertically arranged between the lid mounting frame 10 and the opening / closing lid 12, and the lower end is connected to the lower end of the mounting portion 33 of the lid mounting frame 10 via the bent portion 43, and the upper end is connected to the bent portion 43. The lid 12 is connected to the lower end of the peripheral wall portion 40 of the opening / closing lid 12 through the lid. Other configurations such as the structure of each bent portion 43 are the same as those of the first embodiment.

  In the case where such a hinge 11 is adopted, since the bent portion 43 is provided on both the upper and lower sides of the connecting portion 55, the opening / closing lid 12 is attached by the bending / extending motion of either the upper or lower bent portion 43 or both bent portions 43. It can be opened and closed with respect to the frame 10. Further, since the bent portions 43 are provided on both the upper and lower sides, the opening / closing operation of the opening / closing lid 12 can be made flexible.

  When the cover 12 is closed, the peripheral wall 40 on the hinge 11 side of the cover 12 is engaged with the mounting portion 33 on the hinge 11 side of the cover mounting frame 10, and then the opening and closing is performed using the engaging portion of the both as a fulcrum. When the lid 12 is closed, the peripheral wall 40 of the opening / closing lid 12 can be fitted around the outer periphery of the mounting portion 33 of the lid mounting frame 10.
