Description

  The present invention relates to a paper sealed container. More specifically, the present invention relates to an airtight paper-sealed container that houses an enclosing bag enclosing a wet tissue or the like.

A product in which wet tissues stacked in a laminated form are sealed in a sealed bag formed of a film having airtightness and water resistance is on the market. A long hole-shaped outlet for taking out the wet tissue is provided on the top surface of the enclosing bag, and a sealing seal that can be repeatedly peeled off is applied to cover the outlet in order to prevent the wet tissue from drying. There are many things that have been made.
If there is no sealing seal, or even if there is a sealing seal, once opened, the airtightness will be weakened and the wet tissue may be dried. Therefore, in order to prevent the wet tissue from drying, the enclosing bag may be stored in a more airtight plastic container. The plastic container is generally provided with an opening that is larger than the outlet of the enclosing bag and has a lid that hermetically closes the opening.
However, since this plastic container requires an expensive mold, the production cost is high. Further, when it is discarded, not only is it bulky, but also there is a problem that a high amount of heat and toxic gas are generated during incineration. Another problem is that it cannot be recycled because it is made of plastic.

On the other hand, as shown in FIG. 9, the wet tissue package of Patent Document 1 includes an enclosing bag 104 and an exterior body 101 that covers the outer side, and the exterior body 101 is attached to a paper box 102 and its upper surface. The mold 103 is composed of an annular frame 131 having an opening 132 corresponding to the outlet 143 of the enclosing bag, and a cover plate 133 that seals the opening 132, and the encapsulating bag. The upper surface of 104 and the lower surface of the frame 131 are annularly bonded with an adhesive.
The frame body 131 and the cover plate 133 can be fitted in an airtight manner like a conventional plastic container, and the upper surface of the enclosing bag 104 and the lower surface of the frame body 131 are annularly bonded with an adhesive, The outlet 143 of the enclosing bag is maintained in an almost airtight state when the cover plate 133 is closed. Therefore, the airtightness can be improved despite the fact that the paper box is used. Moreover, compared with what made the whole plastic, it can suppress generation | occurrence | production of the high calorie | heat amount and toxic gas at the time of incineration.

However, plastic is still used as the mold material 103, and there is a problem that an expensive mold is necessary and the manufacturing cost is increased.
In addition, the plastic part and the paper part need to be separated at the time of disposal, and the plastic part still has a problem that a high amount of heat and toxic gas are generated during incineration.
Furthermore, there is a problem that the plastic part cannot be recycled.

  Next, an embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
As shown in FIG. 1, the paper sealed container A according to the first embodiment of the present invention is formed in a plate shape with a box body 10 formed in a rectangular parallelepiped with cardboard and a slip sheet in which the cardboards are laminated together. And the fitted plate 20. The box main body 10 is a conventionally well-known one formed in a rectangular parallelepiped by punching out a piece of thick paper into a shape in which a rectangular parallelepiped is developed in a plane, and bending and bonding each side. The fitting plate 20 is a rectangular paper piece whose strength and thickness are increased by laminating a plurality of thick paper sheets in a laminated form. One surface of the fitting plate 20 is improved in moisture resistance and cosmetics by being laminated.

  The upper surface of the box body 10 is punched so that one side is a broken line 11 and both ends of the broken line 11 are connected in a U-shape. In the present embodiment, the broken line 11 is common with the vicinity of the center of one side of the upper surface of the box body 10. A portion separated from the box body 10 by punching and connected by a broken line 11 is a lid piece 12. An opening formed on the upper surface of the box body 10 is an opening 13, which is the same shape as the lid piece 12 and has a rectangular shape. The lid piece 12 rotates about the broken line 11 so that the opening 13 can be opened and closed. Further, a knob 14 is formed on the lid piece 12, and the lid piece 12 can be easily opened and closed by pinching the knob 14 with a finger.

As shown in FIG. 2, the fitting plate 20 has a larger rectangle than the opening 13. Furthermore, a rectangular lid portion 21 smaller than the opening 13 and an annular frame portion 22 around the lid portion 21 are formed by punching the vicinity of the center into a rectangle.
The lid portion 21 is adhered to the inside of the lid piece 12, and the frame portion 22 is adhered to the inside of the upper surface of the box body 10 so as to surround the opening portion 13. Here, laminating is performed on one surface of the lid portion 21 and the frame portion 22, but the lid portion 21 is bonded so that the surface on which the laminating processing is performed faces the inside of the box body 10, The frame portion 22 is bonded so that the laminated surface faces the outside of the box body 10. That is, after the lid portion 21 and the frame portion 21 are punched from the fitting plate 20, one of them is reversed and bonded to the upper surface of the lid piece 12 and the box body 10. However, the lid portion 21 and the frame portion 22 are bonded to positions that fit each other when the lid piece 12 is closed. Therefore, the lid 21 has a symmetrical shape that fits into the frame 22 even if it is inverted.

  Thus, since the lid piece 12 and the opening portion 13 and the lid portion 21 and the frame portion 22 are formed by punching, they can be fitted with no gap as shown in FIG. 3, and when the lid piece 12 is closed , Airtightness can be increased.

  In addition, the shape in which the box body 10 is developed in a plane is punched out of cardboard, and at the same time, the lid piece 12 and the opening 13 and further the knob 14 can be punched out. At the same time as the fitting plate 20 is punched from the interleaf, the lid portion 21 and the frame portion 22 can be punched out. Therefore, cardboard and interleaf can be used without waste, and the material cost can be suppressed, and the manufacturing process can be reduced and the manufacturing cost can be suppressed.

  In addition, as shown in FIG. 2, it is good also as a shape which provides the broken line 11 in the long side of the upper surface of the box main body 10, and opens the lid piece 12 horizontally, and replaces this with the broken line 11 by the upper surface of the box main body 10 It is good also as a shape which provides in the short side and opens the cover piece 12 vertically long.

  Further, as shown in FIG. 4, the broken line 11 may be provided at a position away from the side of the upper surface of the box body 10, and the shape of the broken line 11 and the upper side of the box body 10 may not be common.

  In this embodiment, one surface of the fitting plate 20 is laminated, the lid portion 22 is made symmetrical, and the lid portion 21 and the frame portion 22 are reversed and bonded together, but both surfaces are laminated. If the fitting plate 20 is used, it can be affixed to the upper surface of the lid piece 12 and the box body 10 in the punched direction. If it does so, fitting with the cover part 21 and the frame part 22 will become better, and airtightness can be improved. Further, in this case, the lid 12 may have an untargeted shape, and can be formed as a free shape together with the shape of the opening 13.

  In addition, the dimensions of the box body 10, the position and size of the lid piece 12, and the fitting plate 20 can be appropriate for the items to be accommodated.

  As described above, since the paper sealed container A is formed only from paper, a plastic mold is unnecessary, and the manufacturing cost can be reduced. In addition, there is no need for separation of plastic members at the time of disposal, and there is no problem that high heat quantity or toxic gas is generated at the time of incineration. It can be recycled in addition to incineration, so it is environmentally friendly and useful for ecology.

As shown in FIG. 5, the sealed paper container A uses an enclosing bag 30 enclosing a wet tissue or the like. The encapsulating bag 30 encloses wet tissues and the like stacked in a laminated manner, and is formed of a film having airtightness and water resistance. The enclosing bag 30 encloses all wet materials such as a skin lotion sheet, a face mask, a wet towel, and a sweat removing sheet in addition to a wet tissue. Hereinafter, in this embodiment, it demonstrates as the enclosure bag 30 which enclosed the wet tissue.
On the upper surface of the encapsulating bag 30, a long hole-shaped outlet 31 for taking out the wet tissue is provided. The enclosed wet tissue can be taken out one by one by pulling out from the take-out port 31, and when the uppermost wet tissue is pulled out, the next wet tissue is exposed from the take-out port 31. Yes. In addition, what has the sealing seal which can be repeatedly peeled off and attached so that it may be covered is suitable for the outlet 31.

Further, since the outer side of the frame portion 22 is also laminated, the frame portion 22 can be protected from the moisture of the taken out wet tissue. Moreover, since the inside of the lid part 21 and the outside of the frame part 22 are visible when the lid piece 12 is opened, the appearance is made beautiful by laminating the part.

  Moreover, since the cover part 21 is formed with a slip sheet, it is heavy. Therefore, after the wet tissue is taken out by hand, the lid piece 12 is closed by its own weight, so that it is not necessary to use a hand closed by the wet tissue and it is easy to handle.

  Furthermore, since the paper sealed container A is formed only of paper, it is possible to print directly not only on the box body 10 but also on the lid piece 12 and the lid portion 21. In the case of a plastic container, a printed seal must be pasted. However, in the case of the present invention, this is not necessary, and printing can be performed simultaneously with the box body, so that the printing cost can be reduced.

(Second Embodiment)
As shown in FIG. 6, the paper sealed container B according to the second embodiment of the present invention has a substantially triangular storage hole 23 formed in the lid portion 21 in the paper sealed container A of the first embodiment. The tweezers 40 can be stored in the storage hole 23. Since the rest of the configuration is the same as in the first embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.
The tweezers 40 are fitted in the storage hole 23 and remain in the storage hole 23 by pressing the side wall of the storage hole 23 with the force of the tweezers 40 spreading.
In order to easily take out the tweezers 40, it is preferable to form a recess 24 into which a finger can be inserted in the side portion of the storage hole 23.

By using the tweezers 40 stored in the storage hole 23, it is possible to cleanly remove the wet tissue from the encapsulating bag without touching the germs on the hand.
Note that the storage hole 23 can be punched at the same time as the fitting plate 20 is punched from the interleaf.

(Third embodiment)
