[Prior art]
FIG. 6 is a perspective view showing an example of a conventional package of this type. The package 101 is made of a sheet material having flexibility and moisture resistance, and an inner bag 102 in which an object to be packaged is enclosed, and an outer box made of a sheet material having appropriate rigidity and covering the outside of the inner bag 102. The inner bag 102 has a takeout port 104 on the top surface and a lid 105 that can be repeatedly opened and sealed by the pressure sensitive adhesive 105a. The outer box 103 is on the top surface. An opening 106 facing the take-out port 104 is provided.
[0003]
[Problems to be solved by the invention]
In the packaging body 101 described above, since the inner bag 102 is made of a flexible sheet material, the upper surface of the inner bag 102 is likely to be wavy, and further, the items to be packaged in the inner bag 102 are reduced. When it comes, there is a space above the package, so that it becomes difficult for the inner surface of the lid 105 to be completely in close contact with the upper surface of the inner bag 102 at the time of resealing, and the quality of the package is incompletely sealed. There was a problem that was damaged.
[0004]
Therefore, as shown in FIG. 7, a frame body 206 having an opening 206 a facing the take-out port 204 of the inner bag 203 on the upper surface of the outer box 202, and a frame body rotatably connected to one side of the frame body 206. A packaging body 201 to which a synthetic resin mold 205 having a lid 207 that seals an opening 206a of 206 is attached has been proposed.
[0005]
However, in the case of this package 201, the mold cost and material cost of the mold 205 are high, so that the cost is high, and the outer box 202 and the mold 205 must be separated at the time of disposal, which is troublesome. There are problems such as this, and there is a problem that toxic gas is generated when the formwork 205 is incinerated, which is not preferable in terms of the environment.
[0006]
The present invention has been made to solve the above-described problems, and its object is a package that can be repeatedly opened and sealed, and can be manufactured at low cost, and is easy to handle and dispose of. It is to provide an excellent one.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.
1 is a perspective view of a package 1 according to an embodiment of the present invention, FIG. 2 is a cross-sectional view taken along line AA ′ in FIG. 1, FIG. 3 is a cross-sectional view taken along line BB ′ in FIG. FIG. 5 is a perspective view showing a partially broken perspective view of the bag 2 and FIG.
[0013]
As shown in FIGS. 1 to 3, the package 1 is made of a sheet material having flexibility and moisture resistance, and includes an inner bag 2 in which a wet tissue laminate W is enclosed, and cardboard, kraft paper, and the like. An outer box 3 that is made of a sheet material having appropriate rigidity and covers the outer side of the inner bag 2 is provided.
[0014]
The outer box 3 includes a top wall 4, a back wall 5, a bottom wall 6, a front wall 7 connected in a row through a fold line, and a pair of flaps 8, 9 connected to both ends of the top wall 4 through a fold line. And. A pair of discontinuous cuts 10 and 10 are formed in the top wall 4 of the outer box 3, and when these are broken, as shown in FIG. 5, the outlet 11 and one side of the outlet 11 are rotated. A lid 12 connected in a possible manner is formed. The tips of the cuts 10 and 10 are bent inward and are continuous with linear cuts 13 and 13 extending in the front-rear direction. The notches 13, 13 each reach the leading edge of the top wall 4, and thereby a knob piece 14 connected to the leading edge of the lid 12 is formed.
[0015]
A rectangular flexible sheet member 15 is attached to the top wall 4 of the outer box 3. The sheet member 15 is formed to be larger than the lid body 12 by a fire-resistant material made of paper, a synthetic resin film, or the like, and the back surface is coated with an adhesive 15 a and covers the cuts 10 and 10. It is bonded to the upper surface of the body 12 and its upper surface. The pressure-sensitive adhesive 15a of the sheet member 15 can be repeatedly peeled off and re-adhered to the surface of the outer box 3. As shown in FIG. When the sheet 12 is peeled off from the peripheral part of the body 12 and the cover 12 is rotated in the closing direction to re-adhere the sheet member 15 to the peripheral part of the cover 12, the take-out port 11 can be resealed.
[0016]
In the present embodiment, the surface of the outer box 3 is polished so that the sheet member 15 can be smoothly peeled, and the sheet member 15 can be peeled and re-adhered repeatedly. Since the surface of the top wall 4 around the body 12 is not damaged, the sealing performance is not lowered. As the polishing process, for example, the surface of the sheet material constituting the outer box 3 is coated with a gloss paint by a coater, the sheet material is forcibly dried by a drying device, and then both surfaces are heated and pressurized by an endless device. Can be used.
[0017]
In the case of such a glazing treatment, for example, a pair of brushing that removes powder from the surface of the sheet material between the coater and a device that supplies the sheet material to the coater as disclosed in Japanese Patent Application Laid-Open No. 59-131460. By providing a powder removal device having a roll and a corona discharge device for corona discharge treatment of the sheet material fed from the powder removal device, and / or by providing a pressure humidification device between the drying device and the endless device, High-quality glazing treatment can be performed without causing poor adhesion of the glazing paint, poor pressure bonding, glazing return, cracking, and the like. Note that the glazing process does not necessarily have to be performed on the entire surface of the outer box 3, and may be performed at least on the portion where the sheet member 15 around the lid 12 is bonded.
[0018]
The inner bag 2 shown in FIG. 4 is a uniaxially stretched synthetic resin film, for example, a sheet material made of a single material or a composite material such as polyethylene, polypropylene, polyester, polyamide, polyvinyl chloride, and aluminum foil, paper, etc. A composite sheet material and the like, and both end portions 16 and 17 orthogonal to the extending direction of these sheet materials are made of a resin made of polypropylene having excellent adhesion and peelability, hot melt lacquer, heat seal It is formed in a cylindrical shape by gluing together through an easily peelable adhesive layer 18 such as lacquer, and is further sealed along both end edges 19 and 20 orthogonal to both side ends 16 and 17. It should be noted that envelope pasting may be used instead of joint palm pasting.
[0019]
The both end portions 16 and 17 of the sheet material are bonded together at a position away from the front end edge of the side end portion 16 so that a free end portion 16a is formed along the front end edge of one side end portion 16. . A large number of fine scars 21 are provided on the leading edge of the side end portion 16 so that the leading edge of the side end portion 16 can be easily cut from an arbitrary position. Since the structure of such a scar 21 is known from Japanese Patent Publication No. 61-39228, Japanese Patent Application Laid-Open No. 64-45262, etc., a detailed description is omitted, but for example, a rotating grindstone, a wire brush, an abrasive grain. It is formed by pressing or rubbing the surface of the sheet material using an entering sheet, an abrasive grain adhesive sheet or the like as an abrasive. Note that a V notch or an I notch may be provided in place of the scar 21.
[0020]
Further, as shown in FIG. 5, a large number of fine scars 22 and 23 are provided along the leading edge of the bonded portion (shown by hatching) of the side end portions 16 and 17, respectively. This is to weaken the adhesive force of the tip edge portion and to make the side end portions 16 and 17 peel off more smoothly. Such a scar may be provided only on one of the side end portions 16 and 17.
[0021]
Further, in the present embodiment, since the side end portions 16 and 17 are smoothly peeled off, as shown in FIG. 5, a saw-tooth shape protruding toward the tip edge side along the bonding portion of one side end portion 16. The convex part 24 is formed. The shape of the convex portion 24 may be a waveform, and the convex portion 24 may be provided on the other side end portion 17. Further, the same effect can be obtained even if the shape of the adhesive layer 18 is a sawtooth shape or a corrugated shape instead of providing such a convex portion 24.
[0022]
The inner bag 2 is housed in the outer box 3 so that the bonded portions of the side end portions 16 and 17 cross the take-out port 11 and the front end edge of the side end portion 16 faces forward. A portion facing the take-out port 11 and behind the tip edge of the side end portion 16 is bonded to the inner surface of the lid 12 via an adhesive layer 25 (see FIGS. 2 and 3). Further, a portion around the take-out port 11 on the upper surface of the inner bag 2 is bonded to the inner surface of the outer box 3 by an adhesive layer 26. In addition, the adhesion location to the inner surface of the outer box 3 of the inner bag 2 is not limited to this.
[0023]
Next, the usage method of the package 1 comprised as mentioned above is demonstrated.
When the tab piece 14 is picked from the state shown in FIG. 1 and a force is applied in the direction in which the lid 12 is raised, the notches 10 and 10 start to break from the tip and the sheet member 15 starts to peel from the tip edge side. When the breakage of the notches 10 and 10 reaches the leading edge of the side end portion 16 of the inner bag 2, the leading edge of the side end portion 16 breaks at the positions at both ends in the takeout port 11, and further pulls up the knob piece 14 The side end portion 16 is broken along the notches 10 and 10, and the adhesive portion located between the notches 10 and 10 in the side end portion 16 is peeled off from the side end portion 17.
[0024]
When the knob piece 14 is pulled until the breaking of the notches 10 and 10 reaches the end, as shown in FIG. 5, the upper surface of the inner bag 2 is torn along the notches 10 and 10 and the lid 12 is completely raised. As a result, an opening 27 facing the take-out port 11 is formed on the upper surface of the inner bag 2, and the wet tissue W can be taken out.
[0025]
When the package 1 is resealed, the knob piece 14 is picked and the lid body 12 is rotated forward, and the lid body 12 and the knob piece 14 are fitted between the cuts 10 and 10 and the cuts 13 and 13, respectively. The inner surface of the sheet member 15 is brought into close contact with the peripheral portion of the lid body 12. Since the notch 10 is covered by the sheet member 15, the takeout port is almost completely sealed, and the quality of the wet tissue W is not impaired.
[0026]
Then, each time the wet tissue W is used, re-sealing and resealing are repeated according to the above procedure, and when the wet tissue W runs out, the package 1 is discarded. Since the package 1 does not use a synthetic resin molded product or a metal part, there is no need for separation, and the package 1 can be discarded as it is. In addition, it is convenient if a fold line extending in the horizontal direction is provided on the side surface of the outer box 3 so that the outer box 3 can be folded into a flat state.
[0027]
In addition, this invention is not limited to the said embodiment, A various change is possible within the meaning of the matter described in the claim.
[0028]
【The invention's effect】
As described above, since the package of the present invention does not use a synthetic resin injection molded product, a metal part, or the like, the mold cost and material cost are low, and the package can be manufactured at low cost. In addition, since no synthetic resin injection molded products or metal parts are used, there is no need for separation at the time of disposal, the handling is good, and there is no generation of toxic gas or unburned residue, so that the disposal is excellent.
[0029]
In the package of claim 2, since the inner bag is formed of a uniaxially stretched film, the inner bag is torn smoothly and the handleability is improved.
[0030]
Since the package of claim 3 is provided with a large number of scars along the leading edge of one side end portion of the inner bag, chips are not generated during production as in the case of providing a notch. , Handling during production is improved. In addition, the inner bag is less likely to break due to an impact during transportation or the like.
[0031]
The package body according to claim 4 is easy to apply a force to the bonded portion of both side end portions by forming the free end portion along the leading edge of one side end portion of the sheet material constituting the inner bag, Both side edges peel off smoothly.
[0032]
The package body according to claim 5 is such that the sheet member is smoothly peeled off by applying a glazing process to at least a portion of the outer box surface to which the sheet member around the lid body is bonded, and the sheet member Even if peeling and re-adhesion are repeatedly performed, the surface of the peripheral portion of the lid body is hardly damaged, so that the sealing performance is not deteriorated.
