Description

The present disclosure relates to a paper container with a chuck, particularly in the field of a paper container having a three-dimensional shape and having self-reliance, and the paper container with a chuck capable of continuously and stably opening and closing the chuck tape repeatedly.

Conventionally, a technique as in Patent Document 1 has been disclosed as a paper container with a chuck. That is, a chuck is provided on the upper part of the rectangular parallelepiped paper container, and the chuck can be opened when the contents are taken out, and the chuck can be closed when the contents have been taken out.

With the above technique, it is possible to protect the contents and prevent the contents from spilling when the paper container falls. In addition, since it is a paper container, it is easy to reduce the volume of the container after consuming the contents and dispose of it. FIG. 1 shows a blank plate 81 used for manufacturing a paper container 80 with a chuck of the prior art, FIG. 2 is a perspective view of the paper container 80 with a chuck of the prior art, and FIG. 3 is a perspective view of a state in which the top is opened. Is shown.

Unless otherwise specified in the future, with reference to FIG. 2, the front side, back side, left side, right side, and top of the paper container 80 with a chuck, with the front side wall plate 831b as the front side. It shall indicate the sword and the bottom sword. The same shall apply to the chucked paper container 90 of the present disclosure.

Further, the reference numerals used when explaining the prior art are in the 80s or 800s in order to distinguish them from the present disclosure.
Further, the subscript a of the reference numeral indicates an element of the back surface portion of the paper container 80 with a chuck, and the subscript b character indicates an element of the front edge portion. In an element with both subscripts a and b, a sign without a subscript shall include both a and b.

In the paper container 80 with a chuck described in Patent Document 1, when the top portion 871 is opened and the contents are swung out, the top surface protruding portion (ear portion) 874 is first removed from the body portion 872. Then, after the easy-opening processing line 851 is cut, the chuck tape 861 is opened and the drawing opening 856 is opened (see FIG. 3).
Then, the contents are drawn out by the paper container 80 with a chuck being lifted and tilted.

Then, in order to swing out the contents, when the front side wall plate 831 of the paper container 80 with a zipper is tilted down, the contents are the front side top plate 833b and the front side upper stacking plate. The inner surface of the 834b slides on the inner surface of the 834b, passes through the front waving chuck tape 861b, and is discharged from the lower edge of the drawing opening 856 (the blank plate 81b of the front waving portion). At that time, the contents may adhere to the chuck tape 861b on the front side, which may hinder the refitting of the chuck tape 861. In particular, when the content is powder or a highly viscous liquid, there have been cases where the refitting of the chuck tape 861 is hindered.

The chuck tape 61 is molded by extrusion molding of a thermoplastic resin or the like, but a resin corresponding to the required performance of each component of the chuck tape 61 (chuck tape body portion 62, chuck tape fitting portion 63, etc.) is adopted. It may be a multi-layer extrusion molding.

It is desirable that the material of the wire bonded to the blank plate 93 of the chuck tape body 62 has a low melting point because it is heat-welded, but the material of the wire to be bonded to the blank plate 93 of the chuck tape body 62 is not bonded. Alternatively, the portion not in contact with the outer surface (the inner layer) may have heat resistance to withstand the temperature of the heat seal.

Examples of the former low melting point material include low density polyethylene (LDPE) and linear low density polyethylene (LLDPE). Examples of the latter heat-resistant material include medium-density polyethylene (MDPE), high-density polyethylene (HDPE), polypropylene (PP), and the like.

Further, the male chuck tape fitting portion 63m may be harder than the female chuck tape fitting portion 63f because it does not need to be deformed when mating with the female chuck tape fitting portion 63f (material). , Hardness due to shape).
The material of the male chuck tape fitting portion 63 m is low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), high density polyethylene (HDPE), polypropylene (PP), etc. Illustrated.

The male chuck tape 61m and the female chuck tape 61f, which are separately extruded, have the male chuck tape fitting portion 63m and the female chuck tape fitting portion 63f, respectively, as shown in FIG. 12 (b). Is fitted to complete the chuck tape 61.

<Chuck tape joining procedure>
The procedure for assembling the paper container 90 with a chuck will be described later, but among the procedures, the procedure for joining the chuck tape 61 will be described here.

In this case, the chuck tape joining portion 52 is a joining portion of the chuck tape 61 when assembling the paper container 90 with a chuck.

The back side blank plate 10a and the front side blank plate 10b are overlapped with each other, and the side edge portions 36 are heat-sealed and the upper seal portions 53 are heat-sealed.
At that time, the chuck tape 61 in which the male chuck tape 61m and the female chuck tape 61f are previously fitted by the male chuck tape fitting portion 63m and the female chuck tape fitting portion 63f is the chuck tape 61. It is inserted into the portion, and at the same time, the chuck tape joint portion 52 is heated and pressurized from the outer surfaces of the two blank plates 93. Then, the blank plate 93 and the chuck tape 61 are heat-sealed.

The bonding of the chuck tape 61 to the blank plate 93 is not limited to the heat seal as described above, and may be bonded by other methods such as an adhesive or an adhesive tape.

Here, an example is shown in which the male chuck tape 61m is the front side chuck tape 61b and the female chuck tape 61f is the back side chuck tape 61a, but the male chuck tape 61m is the back side chuck tape. 61a, and the female chuck tape 61f may be a front side chuck tape 61b.

By heat-sealing the chuck tape 61 by such a method, the position of the heat seal is compared with the method in which the male chuck tape 61m and the female chuck tape 61f are separately heat-sealed to the chuck tape joint portion 52. Since the deviation is reduced and the mounting process is simplified, the chuck tape 61 can be mounted with high production efficiency.

<Laminated sheet of blank plate>
As the laminated sheet 78 used for the blank plate 93, as described above, at least a laminated sheet 78 in which a paper base material layer 782 is laminated and at least an innermost thermoplastic resin layer 783 is laminated with a thermoplastic resin such as polyethylene is used. If necessary, the intermediate layer may be provided with water vapor, oxygen, another barrier layer 785, a strength improving layer, or the like.

Further, when the paper container 90 with a chuck of the present embodiment is provided with a printing layer such as a pattern, printing is normally performed on the surface of the paper base layer 782, but if the printing suitability of the paper base layer 782 is not good, the printing suitability is not good. For example, a biaxially stretched polyethylene terephthalate film or the like may be provided with a printing layer such as a pattern, and the film may be laminated on any of the outer layers of the paper substrate layer 782.

The paper base material layer 782 is preferably paper having rigidity and less likely to crack when bent by a bending line or the like, but is not particularly limited, and is not particularly limited, depending on the contents to be filled in the paper container 90 with a chuck. Suitable ones can be appropriately selected and used in consideration of water resistance (degree of size) and the like.
As a specific example, high-quality paper, bleached kraft paper, cup base paper, milk carton base paper and the like can be preferably used, and the basis weight thereof is appropriately in the range of 80 to 320 g / m ² .

As the resin of the innermost layer and, if necessary, the outermost layer and the heat-adhesive resin layer (sealant layer) of the intermediate layer, low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and medium-density polyethylene are used. (MDPE), high density polyethylene (HDPE), ethylene / α-olefin copolymer polymerized using a single site catalyst, ethylene / vinyl acetate copolymer (EVA), ethylene / acrylic acid copolymer (EAA), Random copolymer of ethylene / methacrylic acid (EMAA), methyl copolymer of ethylene / acrylate (EMA), ethyl copolymer of ethylene / ethyl acrylate (EEA), ionomer, and polypropylene and its copolymers, polyester-based Resins and the like can be used, and from these, suitable ones can be appropriately selected and used according to the contents to be filled and the conditions for storage and use.

Among the above heat-adhesive resins, especially the ethylene / methyl acrylate copolymer (EMA) and the random copolymer of ethylene / methacrylic acid (EMAA) have various bases and thermal stability during processing such as extrusion coating. Since it is excellent in adhesiveness to materials, low-temperature heat-sealing property, and thin film forming property, the outermost heat-adhesive resin layer, which does not require much thickness, is relatively thin, for example, 6 to 10 μm. It is also easy to extrude and coat with a thin thickness and laminate, so that the ratio of plastic materials used can be reduced, and at the same time, a cost advantage can be obtained.

The innermost layer and, if necessary, the outermost layer of the heat-adhesive resin layer are subjected to easy-adhesion treatment such as anchor coating, corona treatment, and frame (flame) treatment as necessary on the laminated surface. After that, the resin can be extruded and coated on it and laminated, or a heat-adhesive resin is formed into a film in advance, and the film is laminated with a known dry laminate or extruded laminate (sandwich laminate). Can be laminated.

When the barrier layer 785 is laminated on the intermediate layer of the laminated sheet 78, the barrier layer 785 is a biaxially stretched polyethylene terephthalate film in which a metal foil such as an aluminum foil, as well as a metal such as aluminum, silica, or alumina or an inorganic oxide is laminated. Hereinafter, a vapor-deposited film having a thickness of 20 to 100 nm is used as a base film such as PET film), biaxially stretched nylon film (hereinafter, ON film), and biaxially stretched polypropylene film (hereinafter, OPP film). Can be done. Alternatively, an ethylene-vinyl acetate copolymer saponified film (hereinafter referred to as EVOH film), a biaxially stretched film of nylon MXD6, a polyacrylonitrile film, and a PET film provided with a coating layer of polyvinylidene chloride, an ON film, and OPP. A film or the like can be used.

It is usually preferable to laminate such a barrier layer 785 on the inner surface of the paper base material layer 782 in that the barrier property can be effectively utilized, but the barrier layer 785 is covered with a metal foil such as aluminum. When a metal-deposited film or a metal-deposited film is used, the metallic feeling is also used in the design, so that the paper base layer 782 can be laminated on the outer surface of the paper base layer 782. The barrier layer 785 can be easily laminated by a known dry laminate, extruded laminate (sandwich laminate), or the like.

The layer structure of the laminated sheet 78 of the blank plate 93 of the paper container 90 with a chuck of this embodiment is illustrated.

Consists of.
This is a layer structure in which the outermost thermoplastic resin layer 781 is removed from the blank plate 93 composed of the five layers shown in FIG. 13 (c).

The bonding between the layers of each of the above laminated sheets 78 is performed by a known dry laminating, extrusion coating, adhesive or the like. The layer for joining between the layers is not shown because it is thin.

The laminated sheet 88 of the conventional chucked paper container 80 is also the same as the laminated sheet 78 of the chucked paper container 90 of the present disclosure.
With reference to FIG. 13, the outermost layer is the thermoplastic resin layer 881, the paper base material layer 882, the innermost layer is the thermoplastic resin layer 883, the intermediate adhesive layer 884, and the barrier layer 885.

<Making a paper container with a zipper>
Below, from the blank plate 93 of the paper container 90 with a chuck, a paper container with a chuck in the intermediate stage (flat state) 91 is manufactured, and further, a paper container with a chuck in the intermediate stage (boxing state) 92 is manufactured, and the contents thereof. The outline of the procedure until the package of the paper container 90 with a chuck filled with the material is completed will be described.

<Making a paper container with a zipper (flat state) in the intermediate stage>
When the above two blank plates 10a and 10b are overlapped with each other, the chuck tape 61 in which the male chuck tape 61m and the female chuck tape 61f are previously fitted at the positions where the chuck tape joints 52 overlap each other. Is inserted, and the chuck tape joint portion 52 is heated, pressurized, and heat-sealed from the outer surface of the blank plate 93.

Next, the inner surfaces of the upper seal portions 53 are heat-sealed, and the inner surfaces of the respective side edge portions adjacent to the side edge portions 11 of the blank plate 93 are heat-sealed. In this way, the lower edge portion 26 is formed in the shape of an open bag.

Further, a notch 77 may be provided at each end of the outer edge portion of the easy-opening processed line 51 (a portion where both sides are in contact with the side edge portion). The notch 77 may be provided at either one end.

The paper container 90 with a chuck is not particularly limited in actual manufacturing, but is a device for assembling the paper container, filling the contents, and sealing each joint in-line in order to improve productivity. May be used.

In the device, a long printed laminated sheet 78 rolled up in a roll shape is unwound, and a paper container is connected side by side to process a bending line, insert a chuck tape 61, heat seal, and a side edge portion. The heat seal of the edge seal allowance 36, the heat seal of the upper seal portion 53, the punching of the notch 77, and the like may be performed.

If the desired paper container 90 with a chuck can be obtained, the order of the steps may be different.

Next, a paper container with a chuck (planar state) 91 in the intermediate stage of the shape shown in FIG. 5 is manufactured by a method of cutting into individual paper containers, and subsequently, molding into a three-dimensional shape is performed, as shown in FIG. A paper container with a chuck (boxing state) 92 in the intermediate stage is manufactured.

<Making a paper container with a zipper (boxing state) in the intermediate stage>
A mandrel is inserted from the opening of the bottom 73 of the paper container with a chuck (flat state) 91 in the intermediate stage, the upper superposition plate 34 is left, and the top plate 33 of the lower part is bent first laterally. The upper stacking plate 34 is erected upward by being spread back and forth by the wire 22.

Here, in order to reliably bend the ridge portion 72d of the body portion 72, the auxiliary member is brought into contact with the vicinity (including contact) of the ridge portion 72d from the inner edge and / or the outer edge of the body portion 72. You may let me.

Below the upper superposition plate 34 is a top portion 71 formed by a top plate 33, followed by a body portion 72 having a substantially rectangular shape in a horizontal cross section, and an intermediate stage chuck in which the bottom portion 73 opens in a substantially rectangular shape. A paper container (boxing state) 92 is formed.
At this stage, as shown in FIG. 6, the upper superposition plate 34 stands upright.

In the design, the shape of the horizontal cross section of the body 72 and the shape of the opening of the bottom 73 are assumed to be rectangular, but the paper container 90 with a chuck made of a flexible laminated sheet 78 mainly made of paper is used. Therefore, it has a substantially rectangular shape, including cases where it does not have a perfect rectangular shape.

<Molding and filling of paper containers with zippers>
Next, the upper stacking plate 34 that stands up in the upward direction is bent over the back surface (the back surface plate 33a) and laid down, and the top projection portion (the top protrusion) that protrudes to both the left and right sides (the back surface plate 33a). The selvage portion) 74 is bent in the direction of the side plate 32 and joined to the body portion 72.

The method of joining may be a method of using an adhesive (hot melt or the like), a method of using an adhesive tape, a method of mechanically joining (a method of engaging, a method of using a joining tool), or the like. Further, when the outermost layer of the blank plate 93 is provided with a thermoplastic resin layer (sealant layer), there is a method in which the thermoplastic resin layer is heat-sealed.
The same method is used for joining the bottom protruding portion (ear portion) 75, which will be described later.

The tip of the top protruding portion (ear portion) 74 may be joined to the body portion 72 of the paper container 90 with a chuck.
Further, a portion other than the tip portion of the top protruding portion (ear portion) 74 may be joined to the body portion 72 of the paper container 90 with a chuck. In that case, the tip of the protruding portion (ear portion) 74 of the top portion does not have to be joined to the body portion 72 of the paper container 90 with a chuck.

The bottom 73 of the intermediate stage chucked paper container (boxed state) 92 formed as described above is directed upwards, filled with the contents from the opening bottom 73, and then the bottom 73 is bent. The bottom part of the seal allowance 37 is heat-sealed in the form of a gassho seal.

After that, the bottom wrapping seal allowance 37 is bent to the back wrapping (back wrapping bottom plate 35a wa) and laid down, and the bottom wrapping protrusion (ear) 75 protruding from both the left and right sides is the bottom. When the face plate 35 is bent and joined to the selvage, a package of a paper container 90 with a chuck having a substantially rectangular parallelepiped shape is completed.

FIG. 7 is a perspective view showing a first embodiment of the chucked paper container 90 of the present disclosure. FIG. 8 is a side view of the paper container 90 with a chuck shown in FIG. 7. FIG. 9 is a plan view of the paper container 90 with a chuck shown in FIG. 7.

The paper container 90 with a chuck shown in FIG. 7 has a substantially rectangular parallelepiped outer shape, and has a ridge portion 72d of a body portion 72 thereof.
Although the design assumes a rectangular parallelepiped paper container 90 with a chuck, the paper container 90 with a chuck made of a flexible laminated sheet 78 mainly composed of paper may not have a perfect rectangular parallelepiped shape. Including, it has a substantially rectangular parallelepiped shape.

<Opening operation for drawing out the contents of a paper container with a zipper>
FIG. 10 is a perspective view showing a state in which the top portion 71 of the package of the completed paper container 90 with a zipper containing the contents is opened for swinging out the contents. Further, FIG. 11 shows a perspective view of the same paper container 90 with a chuck as viewed from the back side.

The easy-opening processing line 51 is opened by a human hand from the notch 77 provided on the side edge portion 11 of one side (here, the right side), and the other side (here, the left side). It is cut up to the edge 11.

Next, the front side opening gripping allowance 57b between the front side easy-opening processing line 51b and the front side side chuck tape 61b, and the back side between the back side side easy-opening processing line 51a and the back side side chuck tape 61a The chuck tape 61 exposed by the easy-opening processing line 51 is opened by grasping the opening gripping allowance 57a by a person's hand and expanding the outside of the chuck-equipped paper container 90 in the direction of the opening.

During the opening operation of the chuck tape 61, the end portion of the side edge portion 11 of each blank plate 93 of the chuck tape 61 is opened to the edge of the side edge portion 36 over substantially the entire width. ..
As described above, the male chuck tape 61m of the chuck tape 61 and the female chuck tape 61f are dissociated to form the swing-out opening 56.

<Characteristics of chuck tape and direction of drawing out contents>
A cross-sectional view of the prior art chuck tape 861 is shown in FIG. FIG. 12A shows a state in which the male chuck tape 861m and the female chuck tape 861f are dissociated. Further, FIG. 12B shows a state in which the male chuck tape 861m and the female chuck tape 861f are fitted together.

Further, since the chuck tape 61 of the present disclosure also has the same shape as described above, it will be described with reference to FIG. As for the reference numerals, the reference numerals for the chuck tape 861 of the prior art and the chuck tape 61 of the present disclosure are shown together.
A cross-sectional view of the chuck tape 61 of the present disclosure is shown in FIG. FIG. 12A shows a state in which the male chuck tape 61m and the female chuck tape 61f are dissociated. Further, FIG. 12B shows a state in which the male chuck tape 61m and the female chuck tape 61f are fitted together.

FIG. 14A shows a cross-sectional view of a chuck tape joint body portion to which the chuck tape 861 and the blank plate 81 are bonded in the prior art, which is cut at the cross-sectional position AA of FIG. Although FIG. 5 is a diagram showing a paper container (planar state) in the intermediate stage of the present disclosure, it is also used for the chuck tape 861 of the prior art for explaining the cross-sectional position.

At this stage, the male chuck tape 861m and the female chuck tape 861f are fitted together.
FIG. 14 (b) shows a cross-sectional view of a state in which the male chuck tape 861 m and the female chuck tape 861 f are released from the state of FIG. 14 (a).

In FIG. 14A, the front side chuck tape 861b is bonded to the blank plate 81b of the front side side portion, and the front side side chuck tape 861b is a female chuck tape 861f.
Further, the backside chuck tape 861a is bonded to the blank plate 81a of the backside portion, and in this figure, the backside chuck tape 861a is a male chuck tape 861m.

FIG. 15 shows the chuck tape joint portion of the present embodiment. In FIG. 15A, the front side chuck tape 61b is bonded to the front side blank plate 10b, and in the present embodiment, the front side chuck tape 61b is a male chuck tape 61m.
Further, the backside chuck tape 61a is bonded to the backside blank plate 10a, and in the present embodiment, the backside chuck tape 61a is a female chuck tape 61f.

Unlike the present embodiment, the front side side side chuck tape 61b may be the female type chuck tape 61f, and the back side side side chuck tape 61a may be the male type chuck tape 61m.
In either case, the chuck tape 61 is a pair of a male chuck tape 61m and a female chuck tape 61f.

Here, in order to draw out the contents, when the front side wall plate 831 of the paper container 80 with a chuck of the prior art is tilted down, the contents are the front side top plate 833b and the front side. The inner surface of the upper stacking plate 834b slides on the inner surface of the upper stacking plate 834b, passes through the front side wadding chuck tape 861b, and is discharged from the edge of the lower side of the drawing opening 856 (the blank plate 81b of the front side waving portion). ..

At that time, the content 89 passes so as to cross the front side of the chuck tape 861b. As shown in FIG. 14, the front side chuck tape 861b is a female chuck tape 861f, and the female chuck tape fitting portion 863f has a recess. Then, when the content 89 passes through, the content 89 invades and accumulates in the recess as shown in FIG. 16A.

Then, when the chuck tape 861 is refitted after the contents have been drawn out and the chucked paper container 80 has been tilted back, the female chuck tape fitting portion is as shown in FIG. 17A. The content 89 was deposited inside the recess of 863f, and the content 89 sometimes prevented the male chuck tape 861 m from being refitted with the female chuck tape 861 f.

Further, when the front side wall plate 31 of the chucked paper container 90 of the present disclosure is tilted downward, the contents 79 have the front side top plate 33b and the inner surface of the front side upper stacking plate 34b. It slides on the wrinkles, passes through the chuck tape 61, and is discharged from the lower wrinkle (front wrinkle blank plate 10b wrinkles) of the drawing opening 56.

At that time, the content 79 passes so as to cross the front side of the chuck tape 61b. As shown in FIG. 15A, the front side chuck tape 61b is a male chuck tape 61m, and the male chuck tape fitting portion 63m has a convex shape, so that even if the contents 79 pass through, the male chuck tape fitting portion 63m has a convex shape. , As shown in FIG. 16B, only a small amount of the content 79 is deposited on the male chuck tape 61 m.

Then, when the chuck tape 61 is refitted after the contents have been drawn out and the chucked paper container 90 has been tilted back, the male chuck tape fitting portion is as shown in FIG. 17 (b). Only a very small amount of the content 79 is deposited on the convex portion of 63 m, and the content 79 does not hinder the refitting of the male chuck tape 61 m and the female chuck tape 61f, so that it is easy. Can be refitted to.
Therefore, the repeated opening and closing of the chuck tape 61 can be continuously stabilized.

As described above, when tilting the paper container 90 with a chuck to shake out the content 79, it is desirable that the content passes over the male chuck tape 61 m. For that purpose, the direction in which the paper container 90 with a chuck is tilted is such that the male chuck tape 61m is on the lower side and the female chuck tape 61f is on the upper side.

For that purpose, when the paper container 90 with a chuck is tilted and the contents 79 are swung out, a display indicating that the male chuck tape 61 m is tilted so as to be downward is displayed as a specific display. Described in container 90.
As the means for displaying the display, printing, sticking an adhesive sticker, stamping, inkjet printing, or the like may be used on the surface of the paper container 90 with a zipper.

Here, consider a case where the front side side side chuck tape 61b is a male type chuck tape 61m and the back side side side chuck tape 61a is a female type chuck tape 61f.
When the contents 79 are drawn out, the front side wall plate 31 is often tilted down, so it is often desirable to use the front side chuck tape 61b as the male chuck tape 61m. ..

In this case, the front side blank plate 10b provided with the male chuck tape 61m is turned down, and the paper container 90 with a chuck is tilted. Then, as a specific display, "on the front blank plate 10b, in particular, at least one place of the front wall plate 31b, the front top plate 33b, and the front upper superposition plate 34b constituting a part thereof. You may describe the indication that "this side is turned down". The specific display is not limited to the specifically described expression as long as the meaning is equivalent.
In FIG. 10, as an example of a specific display, the display "Please swing out with this side facing down" is described on the front surface plate 33b.

Alternatively, on the back side blank plate 10a, in particular, at least one place of the back side wall plate 31a, the back side top plate 33a, and the back side upper superposition plate 34a constituting a part thereof, as a specific display, " You may describe the indication that "this side is turned upside down". The specific display is not limited to the specifically described expression as long as the meaning is equivalent.
A female chuck tape 61f is provided on the back blank plate 10a.
In FIG. 11, as an example of a specific display, the display "Please swing this side up" is described on the back side top plate 33a.

In the example of FIG. 10, a specific display is displayed on the front side blank plate 10b, and in the example of FIG. 11, the specific display is displayed on the back side blank plate 10a.
However, a specific display may be displayed on both the front side blank plate 10b and the back side blank plate 10a. By doing so, the visibility of the specific display is further enhanced, and the possibility that the chucked paper container 90 is tilted in the wrong direction when the contents 79 of the chucked paper container 90 are shaken is reduced.

On the contrary, consider the case where the front side side side chuck tape 61b is the female type chuck tape 61f and the back side side side chuck tape 61a is the male type chuck tape 61m.
In this case, the paper container 90 with a chuck is tilted with the front side blank plate 10b facing up. Then, as an indication to that effect, a specific indication is given to at least one place of the front side wall plate 31b, the front side top plate 33b, and the front side upper stacking plate 34b, which form a part of the front side blank plate 10b. As a result, a display to the effect that "this side is turned upside down" may be described.

Alternatively, as a specific display, "this surface is displayed on at least one of the back wall wall plate 31a, the back top plate 33a, and the back top upper stacking plate 34a, which form a part of the back blank plate 10a. You may write a message saying "I'll make it down."

The above description regarding the drawing direction may be described at least on the front side blank plate 10b or the back side blank plate 10a, or may be provided on both.
Further, the description of the drawing direction may be described somewhere on the outer surface of the paper container 90 with a chuck. Further, although the description of the drawing direction is not described in the paper container 90 with a chuck, it may be described in a document or the like attached at the same time.

<Second embodiment>
The blank plate 93 of the paper container 90 with a chuck of this embodiment is shown in FIG.
The chucked paper container 90 of the present embodiment may be provided with a sharp opening wire 19.

<Aperture sharp line>
The opening sharp line 19 will be described. The blank plate 93 may be provided with a sharp opening wire 19.
Here, a case where the front side chuck tape 61b is a male type chuck tape 61m will be described. Therefore, in this case, when the contents 79 are shaken out, the paper container 90 with a chuck is tilted with the front side blank plate 10b down.

In this case, the sharp opening wire 19 is provided at least on the front blank plate 10b. It is desirable that the opening sharp line 19 is provided on the front side of the blank plate 10b through which the content 79 passes when the content 79 is drawn out, and the front side of the blank plate 10b has the content. It is desirable to join a male chuck tape 61m to which the object 79 does not easily adhere.
That is, it is desirable that the sharp opening wire 19 and the male chuck tape 61m are provided on the same blank plate 93.

Since there is an opening sharp portion 58b formed by the opening sharp line 19, the content 79 is drawn out with a narrow width. Therefore, when the contents are injected into a bottle or the like having a narrow mouth portion, the width of the contents to be drawn out can be narrowed, so that the contents 79 can be transferred without spilling.

In this embodiment, the back side blank plate 10a is also provided with the back side opening sharp line 19a.

Here, the opening sharp line 19 provided on the blank plate 93 is provided on the upper superposition plate 34 and the top plate 33, and the position thereof is substantially the central portion in the width direction of the upper superposition plate 34, and the paper container with a chuck is provided. It extends substantially vertically in the vertical direction of 90.
By doing so, the sharp opening wire 19 can be easily bent. Further, when the content 79 is ejected from the chuck-equipped paper container 90, the direction in which the content is ejected is easily foreseen and therefore easy to be controlled.

The opening sharp line 19 is provided over the entire width of the upper superposition plate 34 and the top plate 33 in the vertical direction. That is, it connects the upper edge portion 21 to the second horizontal bending line 23 via the first horizontal bending line 22.

Here, the portion of the opening sharp line 19 existing in the region of the upper superposition plate 34 is referred to as the first opening sharp line 191, and the portion of the opening sharp line 19 existing in the region of the top plate 33 is referred to as the second opening. The sharp line 192 is used.

The first opening sharp line 191 and the second opening sharp line 192 may be in contact with each other or may be separated from each other.
Further, the first opening sharp line 191 and the second opening sharp line 192 may be on the same line, and may not be on the same straight line as long as the function is not impaired.

The above-mentioned backside blank plate 10a and the front side blank plate 10b, which are overlapped in position, are joined to form a paper container (flat state) 91 with a chuck in an intermediate stage as shown in FIG. An intermediate stage chucked paper container (boxed state) 92 (not shown) is made, and the chucked paper container 90 is completed.
Except for the provision of the sharp opening wire 19, the shape of the laminated sheet 78 of the blank plate 93, the shape of the paper container 90 with a chuck, the assembly method, and the like are the same as those of the first embodiment.

A perspective view of the paper container 90 with a chuck of the present embodiment is shown in FIG. 20, and a plan view is shown in FIG. 21. The difference from the first embodiment is that the opening sharp line 19 is provided.

<Opening for drawing out a paper container with a zipper with a sharp line>
FIG. 22 shows a state in which the top portion 71 of the package of the completed paper container 90 with a chuck containing the contents of the present embodiment is opened for swinging out. The opening means of the paper container 90 with a chuck is the same as that of the first embodiment.

In the open chuck-equipped paper container 90 of the present embodiment, when the content 79 is to be swung out, the swing-out opening 56 through which the content 79 passes has a sharp opening 58b at a substantially central portion in the width direction. It is surrounded by a front side blank plate 10b provided with a front side blank plate 10b and a back side blank plate 10a provided with a back side opening sharpened portion 58a at a substantially central portion in the width direction.
The sharp opening portion 58 is an intersection of the sharp opening line 19 and the easily opened processed line 51 that has been cut and exposed.

The area through which the content 79 passes is near the central portion of the front side blank plate 10b, and since there is a front side opening sharpened portion 58b having a corner portion in this region, the content 79 is swung out narrowly. .. Therefore, when the contents are injected into a bottle or the like having a narrow mouth portion, the width of the contents to be drawn out can be narrowed, so that the contents 79 can be transferred without spilling.

It should be noted that the presence of the sharp line 19a at the back opening makes the front and back of the drawing opening 56 of the paper container 90 with a chuck symmetrical, which may be preferred in appearance.

At the stage when the easy-opening processing line 51 of the paper container 90 with a chuck is cut and the chuck tape 61 is opened, the opening sharp line 19 forming the opening sharp portion 58 is not bent, and therefore the opening sharp portion 58 is formed. Is not sharp.
After the chuck tape 61 is opened, the sharp opening wire 19 is folded into a mountain fold when viewed from the outside by hand in the direction in which the inner surfaces of the blank plate 93 come into contact with each other. 58 can be sharpened.

By the way, when the drawing direction of the contents is the direction in which one of the side plates 32 is turned down and the paper container 90 with a chuck is tilted and taken out (when tilted in the lateral direction), the area through which the contents pass. Since the side edge portion of the lower side has a seal allowance 36, the area through which the contents pass and the container to be injected cannot be brought close to each other, and the contents may be spilled.

Further, in the chucked paper container 90 of the present embodiment, the content 79 does not hinder the refitting of the male chuck tape 61m and the female chuck tape 61f, so that the contents can be easily refitted.
Therefore, the repeated opening and closing of the chuck tape 61 can be continuously stabilized.

<Third embodiment>
The blank plate 93 of the paper container 90 with a chuck of this embodiment is shown in FIG. 23.
The front blank plate 10b of the present embodiment is the same as the front blank plate 10b of the second embodiment shown in FIG. 18, and includes a front opening sharp line 19b.
The back side blank plate 10a of the present embodiment is the same as the back side blank plate 10a of the first embodiment shown in FIG. 4, and the back side opening sharp line 19a is not provided.

Therefore, the front side blank plate 10b and the back side blank plate 10a are not line-symmetrical. However, except for the sharp opening line 19, the upper edge portion 21 is set as a line of symmetry, and the line is symmetric.

The blank plate 93 is assembled, the contents 79 are filled, and the package of the paper container 90 with a chuck is completed. FIG. 24 shows a perspective view of the paper container 90 with a chuck in a state where the easy-opening processing line 51 of the paper container 90 with a chuck is cut and the drawing opening 56 is opened.

In the paper container 90 with a chuck of the present embodiment, the opening sharp line 19 is provided on the front side upper stacking plate 34b and the front side top plate 33b, and the front side opening sharp line 19b is cut off. The intersection with the easy-opening processing line 51b on the front side is the sharpened portion 58b on the front side.

When the paper container 90 with a zipper is tilted with the front side wall plate 31b down and the contents 79 are drawn out, the width of the front side opening sharpened portion 58b becomes narrower.

Therefore, when the content 79 is injected from the chuck-equipped paper container 90 of the present embodiment into a bottle having a narrow mouth portion, the width of the content 79 to be drawn out can be narrowed, so that the content can be narrowed. Can be transferred without spilling, and the amount of drawing out of the content 79 can be easily controlled.

The back side upper layered plate 34a and the back side side top plate 33a are not provided with the back side opening sharp line 19a. Therefore, the cut back side easy-opening processing line 51a has a back side. The region of the upper layered plate 34a has no bent portion and is curved. Therefore, the appearance (design) of the zippered paper container 90 with the top portion 71 opened is different from that of the second embodiment.

According to the chucked paper container 90 of the present embodiment, when the drawing direction of the contents 79 is the direction in which the front side wall plate 31b is turned down and the chucked paper container 90 is tilted and taken out, the contents are taken out. The region through which 79 passes is near the central portion of the front side blank plate 10b, and since there is a front side opening sharpened portion 58b having corners in this region, the contents are swung out narrowly.

Therefore, when the contents are injected from the chuck-equipped paper container 90 of the present embodiment into a bottle having a narrow mouth portion, the width of the contents to be drawn out can be narrowed, so that the contents are reduced to zero. It can be transferred without any work, and it becomes easy to control the amount of the contents to be drawn out.

In this embodiment, the instruction of the tilting direction when the content 79 is swung out from the chucked paper container 90 is not provided by characters or the like. However, since the opening sharp line 19 is provided with only the front opening sharp line 19b, it can be seen that the front opening blank plate 10b is swung down. In this case, the front opening sharp line 19b is a specific display.

Further, as another embodiment of the present embodiment, an example in which a character display is provided on the front surface plate 33b is shown. FIG. 25 shows a perspective view of the paper container 90 with a chuck in which the paper container 90 with a chuck is cut along the easy-opening processing line 51 and the drawing opening 56 is opened.
In this embodiment, since the display is written in characters, the direction in which the paper container 90 with a chuck is tilted is clearer.

Further, in the chucked paper container 90 of the present embodiment, the content 79 does not hinder the refitting of the male chuck tape 61m and the female chuck tape 61f, so that the contents can be easily refitted.
Therefore, the repeated opening and closing of the chuck tape 61 can be continuously stabilized.

<Evaluation>
100 paper containers with chucks from Examples 1 to 10 and Comparative Examples were prepared.
When manufacturing the paper container 80 with a chuck of the comparative example, there was a step of bending the blank plate 81 at the intermediate horizontal bending line (half-folding line) 821. (See FIG. 1). In that process, an event was observed in which the adjacent easy-opening processed line (perforation line) 851 was erroneously bent. When the easy-opening processed line (perforation line) 851, which should not be bent normally, is bent, the blank plate 81 becomes a defective product, resulting in loss.

This is because the easy-opening processed line (perforation line) 851 has many cut portions (including half-cut) in order to ensure easy-opening property, and is easily bent unintentionally. The ease of bending of the easy-opening processed line (perforation line) 851 is often the same as the ease of bending of the intermediate horizontal folding line (half-folding line) 821, and when the paper container 80 with a chuck is manufactured. Although the intermediate horizontal folding line (half-folding line) 821 is carefully bent, the adjacent easy-opening processed line (perforation line) 851 may be bent by mistake.

Further, if an attempt is made to bend the intermediate horizontal folding line (half-folding line) 821 more carefully, the time required for manufacturing the paper container 80 with a chuck increases. As a result, the manufacturing capacity of the paper container 80 with a chuck may decrease.

On the other hand, in the present disclosure in which two blank plates 10a and 10b are joined to form a paper container 90 with a chuck, there is no intermediate horizontal bending line, and therefore there is no step of bending the intermediate horizontal bending line. There is no problem of accidentally bending the easy-opening processed line (perforation line) 851 as in the above.
Therefore, in the paper container 90 with a chuck of the present disclosure, the manufacturing capacity thereof does not decrease, and the occurrence of defects can be reduced.

The chucked paper containers 90 of Examples 1 to 10 prepared as described above were filled with flour as contents from the bottom 73, respectively. Next, the bottom portion 73 was folded in, and the bottom portion was heat-sealed, and the heat-sealed portion was laid down in the direction of the back cover bottom plate 35a.

Further, the bottom protruding portion (ear portion) 75 protruding from both the left and right sides of the bottom 73 of the paper container 90 with a chuck is bent into the bottom plate 35. Further, the front side bottom plate 35b and / or the front side bottom portion was joined to the front side seal allowance 37b with an adhesive (hot melt) to complete a package of a paper container 90 with a chuck having a substantially rectangular parallelepiped shape.
The top protruding portion (ear portion) 74 of the paper container 90 with a chuck was also bonded to the body portion 72 by using an adhesive (hot melt) before filling the flour.

Further, the chucked paper container 80 of the comparative example was filled with flour as the content from the bottom 873. Next, the bottom portion 873 was folded in, and the bottom portion was heat-sealed, and the heat-sealed portion was laid down in the direction of the back cover bottom plate 835a.

Further, the bottom protruding portion (ear portion) protruding from both the left and right sides of the bottom 873 of the paper container 80 with a chuck of the comparative example was bent into the bottom plate 835. Further, the front side bottom plate 835b and / or the front side bottom part was joined to the front side seal allowance 837b with an adhesive (hot melt) to complete a package of a paper container 80 with a chuck having a substantially rectangular parallelepiped shape.
The top protruding portion (ear portion) 874 of the paper container 80 with a chuck of the comparative example was also bonded to the body portion 872 by using an adhesive (hot melt) before filling the flour.

Further, with respect to the package of the paper container 90 with a chuck of Examples 1 to 10 produced as described above and the package of the paper container 80 with a chuck of the comparative example, the opening property, the suitability for drawing out the contents, and the chuck tape Was tested for resealability.

The upper seal portion 53 was easily cut off by the notch 77 provided at one end, and the swing opening portion 56 was formed.

Next, the opening gripping allowance 57 of the opened drawing opening 56 was gripped and both were pulled apart from each other, so that the fitting of the chuck tape 61 could be easily dissociated.
Further, the drawing opening 56 at the upper part of the package of the paper container 90 with a chuck is opened over substantially the entire width of the paper container 90 with a chuck.

Next, the opening sharp line 19 of the chucked paper container 90 of Examples 2 to 9 was folded in a mountain shape when viewed from the outside of the chucked paper container 90, and the opening sharpened portion 58 was provided in the drawing opening 56.
Even when the opening sharp line 19 is not in contact with the easy-opening processed line 51, the opening sharp line 19 extends to the upper side and breaks, so that the opening sharp portion 58 is formed.

Further, the opening auxiliary line 55 of the chucked paper container 90 of Examples 8 to 10 was folded in a mountain shape when viewed from the outside of the chucked paper container 90. Further, when the drawing opening 56 is opened, the upper stacking plate 34 and / or the side plate 41 and / or the top plate 33 and / or the top plate 33 and / or the top plate protrusion (ear portion) allowance 38 of the top portion. Deformation could be done more smoothly by properly bending the opening auxiliary line 55.

In Examples 1 to 10, a paper container 90 with a chuck is provided so that the front side blank plate 10b is on the bottom, that is, the male chuck tape 61m, which is the front side chuck tape 61b, is on the bottom. A part of the flour was sprinkled out.

After that, when the tilt of the paper container 90 with a chuck was returned, the chuck tape 61 was refitted, and the paper container 90 with a chuck was resealed, the paper container 90 with a chuck could be resealed well, and the remaining flour was properly stored. I was able to.

Further, in the paper container 90 with a chuck of Examples 2 to 9, the flour is narrowly shaken out from the opening sharp portion 58 having a corner portion (or a curve having a small radius of curvature) formed by the opening sharp line 19. So it was easily transferred to a table jar.

Further, the opening auxiliary line 55 of the paper container 90 with a chuck of Examples 8 to 10 stabilizes the shape of the drawing opening 56, and the depth direction of the drawing opening 56 becomes large and the width direction becomes small. The shape makes it easy for flour to be sprinkled out.

On the other hand, also in the package of the paper container 80 with a zipper of the comparative example, the easy-opening processing line 851 was cut to form a drawing opening 856.
Then, the fitting of the chuck tape 861 was dissociated, and the swing-out opening 856 at the upper part of the package of the chuck-equipped paper container 80 was opened over substantially the entire width of the chuck-equipped paper container 90.

Then, the paper container 80 with a chuck is tilted so that the blank plate 81b on the front side is turned down, that is, the female chuck tape 61f, which is the front sided chuck tape 861b, is turned down. , A part of the flour was sprinkled out.

After that, when the tilt of the paper container 80 with a chuck was returned and the chuck tape 861 was visually recognized, the flour had invaded and accumulated in the recess of the female chuck tape fitting portion 863f.

After that, when the chuck tape 861 was refitted and the paper container 80 with a chuck was tried to be resealed, the refitting of the chuck tape was hindered by the flour accumulated in the recess of the female chuck tape fitting portion 863f. There was a case of being. Therefore, there have been cases where the paper container 80 with a zipper cannot be resealed well and the remaining flour cannot be properly stored.

Further, in the paper containers 90 with chucks of Examples 1 to 10, the mass ratio of paper to the total mass of the paper container is about 60% by mass, which sufficiently satisfies the standard of 51% by mass or more as a paper container. there were.
