In addition, the order of ruled line processing and punching processing does not matter. It may be processed at the same time.

Further, a roll-shaped laminated sheet slit to a predetermined roll width may be supplied to a machine for manufacturing a paper container 90 with a chuck and cut in the transverse direction of the roll-shaped laminated sheet to produce a blank plate 93. ..

Further, the back side blank plate 10a is line-symmetrical and has the same shape as the front side blank plate 10b except for some components (opening sharp line 19, opening auxiliary line 55, etc., which will be described later). In other words, it is a blank plate having almost the same shape in which the layer structure of the blank plate is reversed.

The front side upper stacking plate 34b and the side plate 41b at the top of each front side are provided with a front side easy-opening processing line 51b as an opening means.
By providing the easy-opening processing line 51b, the paper container 90 with a zipper can be opened without using tools such as scissors.

When the inner surfaces of the back side blank plate 10a and the front side blank plate 10b are aligned and overlapped with each other, the front side upper overlapping plate 34b and the front side side plate 41b of each front side are formed. At a predetermined position where the above-mentioned two blank plates overlap each other, as will be described later, a front cover upper seal portion 53b and a front cover chuck tape joint portion 52b (shown in FIG. 6) as sealing means in the transverse direction. ), And the upper edge portion 21b of the front side is provided in order from the side.

The front-side easy-opening processing line 51b exists between the front-side upper seal portion 53b and the front-side chuck tape joint portion 52b.
The chuck tape 61 is exposed by opening the front-side easy-opening processing line 51b existing between the front-sided upper seal portion 53b and the front-sided chuck tape joint portion 52b. By opening the exposed chuck tape 61, the contents can be shaken out.

The easy-opening processing line 51b may not be provided depending on the material, layer structure, easy-opening processing status, etc. of the laminated sheet of the front-side blank plate 10b. Even if there is no easy-opening processing line 51b, it may be possible to open it by hand.

Further, the easy-opening processing line 51b may be opened with a knife such as scissors. In that case, the scheduled opening line may be displayed by printing. Further, it may be printed at the position of the easy-opening processing line 51b shown in FIG. Further, the paper container 90 with a zipper may be described in an attached instruction manual or the like without clearly indicating the scheduled opening line.

FIG. 6 is a front view showing the shape of the chucked paper container (flat state) 91 in the intermediate stage when the chucked paper container 90 is manufactured using the blank plate 93 shown in FIG. The uppermost portion is the upper edge portion 21b of the front side blank plate 10b shown in FIG. 5B, and the back side blank plate 10a is provided on the back side. The back side blank plate 10a cannot be seen, but when viewed through, the front side blank plate 10b and some components (opening sharp line 19, opening auxiliary line 55, etc.) have the same shape.

In FIG. 6, the back side blank plate 10a and the front side blank plate 10b overlap each other, and each component (excluding some of the above components) is shown in the drawings within the range of manufacturing variation. Since the positional relationship is the same when viewed through, the notation and subscripts on the table may be omitted in the explanation.

The upper overlapping plate 34 and the side plates 41 at the top of each have an upper sealing portion 53 as a sealing means in the transverse direction at a predetermined position where the above-mentioned two blank plates overlap each other, as described later. The chuck tape joint portion 52 and the chuck tape joint portion 52 are sequentially provided from the upper edge portion 21.

The upper seal portion 53 is provided in the vicinity of the upper edge portion 21 of the upper overlapping plate 34 and the side plate 41 of each top portion, or the upper edge portion 21.
When the upper seal portion 53 is substantially parallel to the upper edge portion 21, the length of the upper seal portion 53 can be shortened, and the blank plate 93 is not wasted.

The upper seal portion 53 as a sealing means in the transverse direction is formed by joining the front side upper seal portion 53b and the back side upper seal portion 53a which are opposed to each other. Since the joining is performed so as to cross the upper edge portion 21 of the chucked paper container 90 or the vicinity of the upper edge portion 21 over the entire width, the sealedness of the chucked paper container 90 is maintained.

Further, it is desirable that the upper seal portion 53 is substantially parallel to the upper edge portion 21. Further, it is desirable that the chuck tape joint portion 52 is substantially parallel to the upper edge portion 21.
In such a form, the chuck tape 61 can be easily opened and closed and the contents can be easily taken out. Further, the length of the chuck tape 61 can be shortened.

<Easy opening processing line>
The easy-opening processing line 51 will be described.
In FIG. 6, the easy-opening processing line 51 is connected from the side edge portion 11 of one blank plate 93 to the side edge portion 11 of the other blank plate 93, and exists between the upper seal portion 53 and the chuck tape 61. ..
A notch 77 may be provided at either end of the easy-open processing line 51, and in this embodiment, the notch 77 is provided at the side edge 11 of the blank plate 93 on the right side. The notch 77 may be provided on the side edge portion 11 of the blank plate 93 on the left side. By providing the notch 77, the initial opening is facilitated.

By cutting the easy-open processing line 51 from one side edge portion (here, the right side) 11 and reaching the other side edge portion (here, the left side) 11, the upper overlapping plate 34 is cross-sectional. The chuck tape 61 is exposed.

When an intermittent half-cut line or a linear half-cut line is used for the easy-opening processing line 51 of the opening means, it may be formed by a method using a normal blade, but a method using laser light irradiation, By using a method using ultrasonic waves or a method called diamond cut, a half-cut line having more accuracy and stability can be formed.

Further, the easy-opening processing line 51 may have a strip shape having a width. Further, a plurality of easy-opening processing lines 51 may be provided.

<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 37 are heat-sealed and the upper seal portions 53 are heat-sealed.
At that time, the chuck tape 61 in which the male tape body and the female tape body are previously fitted at their fitting portions is inserted into this portion, and at the same time, the outer surfaces of the two blank plates 93 can be seen from the chuck tape. This is performed by a method in which the joint portion 52 is heated, pressurized, and heat-sealed.

The chuck tape 61 is not limited to the heat seal as described above, but may be joined by other methods such as an adhesive or an adhesive tape.

By heat-sealing the chuck tape 61 in this way, the position of the heat-seal is displaced as compared with the method of heat-sealing the male tape body and the female tape body separately to the chuck tape joint portion 52. Since the number of tapes is reduced and the mounting process is simplified, the chuck tape 61 can be mounted with high production efficiency.

<Laminated sheet of blank board>
As the laminated sheet used for the blank plate 93, as described above, a laminated sheet in which a paper base material layer is laminated on at least an intermediate layer and a heat-adhesive resin such as polyethylene is laminated on at least the innermost layer is used. If necessary, a water vapor, oxygen or other gas barrier layer, a strength improving layer, or the like can be provided. Further, the heat-adhesive resin may be laminated on the outermost layer.

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 usually performed on the surface of the paper base material layer, but if the printing suitability of the paper base material layer is not good, for example, It is also possible to provide a printing layer such as a pattern on a biaxially stretched polyethylene terephthalate film or the like, and laminate the film on the outer edge of the paper base material layer. Further, the outermost layer of the heat-adhesive resin layer may be printed on the outer surface.

The paper base material layer is preferably paper that is rigid and does not easily crack when bent along a bending line or the like, but is not particularly limited and is water resistant depending on the contents to be filled in the zippered paper container 90. Appropriate ones can be appropriately selected and used in consideration of the property (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 ^{90 to 320 g / m 2.}

As the resin of the heat-adhesive resin layer (sealant layer) of the innermost layer and / or the outermost layer, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), medium density polyethylene (MDPE), and high density are used. Random polyethylene (HDPE), ethylene / α-olefin copolymer polymerized using a single site catalyst, ethylene / vinyl acetate copolymer (EVA), ethylene / acrylic acid copolymer (EAA), ethylene / methacrylic acid Use copolymer (EMAA), ethylene / methyl acrylate copolymer (EMA), ethylene / ethyl acrylate copolymer (EEA), ionomer, polypropylene and its copolymer, polyester resin, etc. 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, ethylene / methyl acrylate copolymer (EMA) and ethylene / methacrylic acid random copolymer (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, etc., and also in 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 it is possible to reduce the ratio of plastic materials used, and at the same time, it is possible to obtain an advantage in terms of cost.

The heat-adhesive resin layer of the innermost layer and / or the outermost layer as described above is subjected to easy-adhesion treatment such as anchor coating, corona treatment, and frame (flame) treatment on the laminated surface as necessary. In addition to being able to extrude and coat the resin on top, a heat-adhesive resin can be formed into a film in advance, and the film can be laminated by laminating with a known dry laminate or extruded laminate (sandwich laminate). Can be done.

When the gas barrier layer is laminated on the intermediate layer of the laminated sheet, the gas barrier layer is a biaxially stretched polyethylene terephthalate film (hereinafter referred to as PET) obtained by biaxially stretching a metal foil such as an aluminum foil, a metal such as aluminum, silica, or alumina, or an inorganic oxide. A vapor-deposited film deposited to a thickness of 20 to 100 nm can be used as a base film such as a biaxially stretched nylon film (hereinafter, ON film) and a biaxially stretched polypropylene film (hereinafter, OPP film). 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 that such a gas barrier layer is laminated on the inner surface of the paper base material layer of the intermediate layer in that the gas barrier property can be effectively utilized, but a metal foil such as aluminum is used for the gas barrier layer. When a metal-deposited film or a metal-deposited film is used, the metallic feeling is also used in the design, so that the outer surface of the paper base material layer can be laminated on the outer surface. The gas barrier layer can be easily laminated by a known dry laminate, extruded laminate (sandwich laminate), or the like.

<Procedure for manufacturing a paper container with a zipper>
Below, from the blank plate 93 of the paper container 90 with a chuck, the paper container with a chuck (flat state) 91 in the intermediate stage is manufactured, and until the package of the paper container 90 with a chuck filled with the contents is completed. The outline of the procedure of is explained.

The above-mentioned crushed portion can be provided by pressing the outer surface of the laminated sheet with a hot press or the like to crush the chuck tape 61 and deforming it so that the thickness becomes thin.

The paper container 90 with a chuck is not particularly limited in actual manufacturing, but is a device that assembles the paper container, fills the contents, and seals each joint in-line in order to improve productivity. May be used.
In the device, a long printed laminated sheet rolled up in a roll shape is unwound, and a paper container is connected side by side to process a folding line, insert a chuck tape 61, and heat-seal each side edge. The heat seal of the portion seal allowance 37, 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 other than the above.

Next, a paper container with a chuck (planar state) 91 in the intermediate stage of the shape shown in FIG. 6 is produced 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 (in the boxed state) 92 in the intermediate stage is manufactured.

After the paper container with chuck (boxing state) 92 in the intermediate stage is manufactured, as shown in FIG. 8, the upper stacking plate 34 and the side plate 41 at the top are bent to the back side, and both sides are folded. The protruding portion (ear portion) 74 of the top portion of the paper container 90 is joined to the body portion 72 of the paper container 90 with a chuck, and the contents are filled from the bottom portion 73 of the paper container 90 with a chuck with the opening bottom portion 73 facing up. NS.

Next, heat sealing is performed between the bottom surface sealing allowances 38, and the back surface is bent into the surface.
After that, the bottom protruding portion (ear portion) 75 protruding from both sides of the bottom 73 of the paper container 90 with a chuck is bent and heat-sealed to the bottom plate 35, and the package of the paper container 90 with a chuck is formed. Can be completed.

FIG. 8 is a perspective view showing a first aspect of the first embodiment of the paper container 90 with a chuck of the present invention. FIG. 9 is a side view of the paper container 90 with a chuck shown in FIG. FIG. 10 is a plan view of the paper container 90 with a chuck shown in FIG.

The paper container 90 with a chuck shown in FIG. 8 has a substantially rectangular parallelepiped outer shape, and has a ridge portion 72d on its body portion 72.
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 mainly composed of paper includes a case where the paper container 90 does not have a perfect rectangular parallelepiped shape. , It has a substantially rectangular parallelepiped shape.

Such a paper container 90 with a zipper can be produced by the following procedure.
For example, using the blank plate 93 having the configuration shown in FIG. 5, the inner surfaces of the two blank plates 10a and 10b are overlapped with each other after being aligned as shown in FIG. 6, and the chuck tape joint portions 52 are overlapped with each other. A chuck tape 61 in which a male tape body and a female tape body are previously fitted is inserted at a position where the male tape bodies and female tape bodies are fitted in advance, and the chuck tape joint portion 52 is heated and pressurized from the outside of the blank plate 93 to be heat-sealed. NS.

Subsequently, the side edge portions 11 of the blank plates 93 are heat-sealed with each other, and the upper seal portions 53 are heat-sealed with each other.
Further, a notch 77 is provided at the end of the side edge portion 11 of the blank plate 93 on one side of the easy-opening processing line 51 (here, the right side), and the bottom side seal allowance 38 opens unsealed. A paper container (flat state) 91 with a chuck in an intermediate stage having a folded shape is produced.

Next, a mandrel is inserted through the opening of the bottom 73 of the paper container with a chuck (flat state) 91 in the intermediate stage, the upper stacking plate 34 is left, and the top plate 33 of the lower side thereof is first. The upper overlapping plate 34 is erected upward by being spread back and forth by the horizontal bending line 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.

Underneath the upper stacking plate 34 is a top 71 formed by a top plate 33, followed by a body 72 having a substantially rectangular horizontal cross section, and an intermediate stage chuck in which the bottom 73 opens in a substantially rectangular shape. A paper container (boxed state) 92 is formed.
At this stage, as shown in FIG. 7, the upper stacking plate 34 stands upright.

In the design, the shape of the horizontal cross section of the body portion 72 and the shape of the opening of the bottom portion 73 are assumed to be rectangular, but it is a paper container 90 with a chuck made of a flexible laminated sheet mainly composed of paper. Therefore, the shape is substantially rectangular, including the case where the shape is not completely rectangular.

(Molding and filling of paper containers with zipper)
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 portion that protrudes to both the left and right sides protrudes. The (ear 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). 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 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 portion 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 top protruding portion (ear portion) 74 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 contents from the opening bottom 73, and then the bottom 73 is bent. The bottom part of the seal allowance 38 is heat-sealed in the form of a gassho seal.

After that, the bottom wrapping seal allowance 38 is bent by the back ridge (back ridge bottom plate 35a ridge) and laid down, and the bottom ridge protrusion (ear) 75 that protrudes to both the left and right sides By bending the bottom plate 35 into a sill and joining them, a package of a paper container 90 with a chuck having a substantially rectangular parallelepiped shape is completed.

<Opening for drawing out a paper container with a zipper>
FIG. 11 shows 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 easy-opening processing line 51 is manually opened from the notch 77 provided on the side edge portion 11 of the blank plate 93 on one side (here, the right side), and the other side (here, the left side is). W) is cut up to the side edge 11 of the blank plate 93.

Next, the front side opening gripping allowance 57b between the front side opening processing line 51b and the chuck tape 61, and the back side opening gripping allowance 57a between the back side opening easy opening processing line 51a and the chuck tape 61. The chuck tape 61 exposed by the easy-opening processing line 51 is opened by grasping each of the paper containers 90 with a human hand and expanding the outer side of the paper container 90 with a chuck in the direction of the edge.

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 up to the edge portion 37 of the side edge portion.

Here, FIG. 12A shows the edge portion of the upper ridge when the paper container 80 with a chuck with an opening of the prior art is viewed from above.
The drawing direction of the contents is a direction in which the paper container 80 with a zipper is tilted and taken out with the front wall plate 831b as the lower side. In FIG. 12A, the blank plate 81b on the front side is the bottom side.
As shown in FIG. 12A, the drawing opening 856 for drawing out the contents is surrounded by a curve having a large radius of curvature for both the blank plate 81b on the front side and the blank plate 81a on the back side. ..

The region through which the contents pass is near the central portion of the blank plate 81b at the front edge portion, and this region has a gentle curve, and the contents are widely drawn out. Therefore, when injecting the contents into a bottle having a narrow mouth portion, the width of the contents to be drawn out cannot be narrowed, and the contents may be spilled.

On the other hand, FIG. 12B shows the edge portion of the upper edge of the paper container 90 with an open chuck of the present embodiment when viewed from above. The opening 56 for drawing through which the contents pass when the contents are drawn is a blank plate 10b having a sharp opening 58b at a substantially central portion in the width direction and a substantially central portion in the width direction. It is surrounded by a blank plate 10a on the back side portion provided with a sharp opening portion 58a.

The region through which the contents pass is near the central portion of the blank plate 10b at the front edge portion, and since there is a sharp opening portion 58b having a corner portion in this region, the contents are swung out with a narrow width. Therefore, when the contents are injected into a bottle having a narrow mouth portion, the width of the contents to be drawn out can be narrowed, so that the contents can be transferred without spilling.

In the above description, the drawing direction of the contents is an example in which the paper container 90 with a zipper is tilted with the front side wall plate 31b down, but the back side wall plate 31a is down. In some cases, the paper container 90 with a chuck can be tilted. In that case, a sharp opening portion 58a may be provided on the blank plate 10a of the back edge portion.

Further, both the blank plate 10b on the front edge portion and the blank plate 10a on the back edge portion may be provided with the sharp opening portion 58. By doing so, the contents are drawn out from the front side or the back side of the paper container 90 with a chuck for the convenience of the user.

At the stage when the easy-to-open processing line 51 of the top portion 71 of the paper container 90 with a chuck is cut and the chuck tape 61 is opened, the sharp opening wire 19 forming the sharp opening portion 58 is not bent, and therefore, The sharp opening 58 is not sharp.
After the chuck tape 61 is opened, the opening sharp line 19 is folded in a mountain fold when viewed from the outside in the direction in which the inner surfaces of the blank plate 93 come into contact with each other by hand work or the like. 58 can be sharpened.

Further, the method of creating the blank plate 93 and the like have mainly described the front side blank plate 10b, but the shape of the back side blank plate 10a is a partial component (opening sharp line 19 and opening auxiliary line). It is the same except for (55, etc.), is line-symmetrical with the upper edge portions 21a and 21b as the axes of symmetry, and the manufacturing method is the same. Therefore, the description of the back blank plate 10a is omitted.

Further, the description of the present embodiment will be described on the front and back blank plates 93, that is, on the front and back blank plates 10b, the front and back opening sharp lines 19b and the front and back opening sharpened portions 58b, and the back and back blank plates 10a. An example in which the back edge opening sharp line 19a and the back edge opening sharp portion 58a are provided has been mainly described.

However, without being bound by this example, the front side blank plate 10b may have the opening sharp line 19b and the opening sharp portion 58b, and the back side blank plate 10a may have the opening sharp line 19a and the opening sharp portion 58a. There may be.
The same applies to each embodiment and each aspect described below.

According to the paper container 90 with a zipper of this aspect, when the drawing direction of the contents is the direction in which the front wall surface plate 31b is downward and the paper container 90 with a zipper is tilted and taken out, the contents pass through. The region to be formed is near the central portion of the blank plate 10b, and since there is a sharp opening portion 58b having a corner portion in this region, the contents are narrowly drawn out.

Therefore, when the contents are injected from the paper container 90 with a chuck of this 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 eliminated. It can be transferred without having to move, and it becomes easy to control the amount of the contents to be drawn out.

Further, when the drawing direction of the contents is a direction in which one of the side plates 32 is lowered and the paper container 90 with a chuck is tilted and taken out, the side edge of the lower side of the area through which the contents pass passes. Since the portion has a seal allowance 37, the area through which the contents pass cannot be brought close to the container to be injected, and the possibility of spilling the contents increases.

<< Second aspect of the first embodiment >>
A second aspect of the first embodiment will be described with reference to FIGS. 13 and 14. FIG. 14 shows the shape of the paper container (flat state) 91 in the intermediate stage when the paper container 90 with a chuck is manufactured using the blank plate 93 shown in FIG.

The opening sharp line 19 of this embodiment is present on both the upper stacking plate 34 and the top plate 33, as in the first aspect.

However, the first opening sharp line 191 is not present in the entire width of the upper stacking plate 34 in the vertical direction, but is partially present. In FIG. 13, the first opening sharp line 191 is in contact with the first lateral bending line 22, and is not in contact with the upper edge portion 21.

Further, the first opening sharp line 191 may not be in contact with the first lateral bending line 22 but may be in contact with the upper edge portion 21.
Alternatively, the first opening sharp line 191 may not be in contact with both the first lateral bending line 22 and the upper edge portion 21.

Further, the second opening sharp line 192 is not the full width of the top plate 33 in the vertical direction, but is partially present. In FIG. 13, the second opening sharp line 192 is in contact with the first lateral bending line 22, and is not in contact with the second lateral bending line 23.

Further, the second opening sharp line 192 may not be in contact with the first lateral bending line 22, but may be in contact with the second lateral bending line 231.
Alternatively, the second opening sharp line 192 may not be in contact with both the first lateral bending line 22 and the second lateral bending line 23.

The dimensions, shape, material, and the like other than the sharp opening wire 19 are the same as those in the first aspect.

In the paper container 90 with a chuck of this aspect, the sharp opening line 19 is shorter than that of the first aspect, but a sufficient sharpness of the sharp opening 58 can be obtained depending on the contents, the application, the material of the blank plate 93, and the like.
Therefore, when the contents are injected from the paper container 90 with a chuck of this 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 eliminated. It can be injected without the need for injection, and the amount of the contents drawn out can be easily controlled.

<< Third aspect of the first embodiment >>
This aspect will be described with reference to FIG. FIG. 15 shows the shape of the paper container (flat state) 91 in the intermediate stage when the paper container 90 with a chuck is manufactured.

The difference from the first aspect is that the first opening sharp line 191 exists in the entire vertical width of the upper stacking plate 34, that is, the first opening sharp line 191 has the upper edge portion 21 and the first horizontal bending line 22. The second opening sharp line 192 does not exist.

The dimensions, shape, material, and the like other than the sharp opening wire 19 are the same as those in the first aspect.

In the paper container 90 with a chuck of this embodiment, the sharp opening wire 19 is shorter than that of the first aspect, but a sufficient sharpness of the sharp opening 58 can be obtained depending on the content, application, material of the blank plate 93, and the like.
In particular, since the first opening sharp line 191 exists in the chuck tape joint portion 52 which is difficult to bend, the opening sharp line 19 is easily bent over the entire surface, and the opening sharp line 58 is easily formed.

≪Evaluation≫
50 paper containers with zippers of Examples 1 to 15 and Comparative Examples 1 and 2 were prepared and evaluated.

When producing the paper container 80 with a chuck of Comparative Example 1, there was a step of bending the blank plate 81 along 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 processing line (perforation line) 851 was erroneously bent. If the easy-to-open processing 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 processing line (perforation line) 851 has many cut parts (including half-cut) in order to ensure easy-opening property, and it is easy to be bent unintentionally. The ease of bending of the easy-opening processing 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 processing line (perforation line) 851 may be bent by mistake.

Further, if an attempt is made to bend the intermediate horizontal bending line (half-folding line) 821 more carefully, the time required for manufacturing 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 prepare 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 defect that the easy-to-open processing line (perforation line) 51 is accidentally bent 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 15 and Comparative Examples 1 and 2 prepared as described above were filled with salt 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) 75 protruding from both the left and right sides of the bottom 73 is bent into the bottom plate 35, and heats to the front bottom plate 35b and / or the front bottom plate seal allowance 38b. Sealed to complete the packaging of the substantially rectangular parallelepiped shaped paper containers 90 with chucks of Examples 1 to 15 and Comparative Examples 1 and 2.

In addition, the packaging of the paper containers 90 with zippers of Examples 1 to 15 and Comparative Examples 1 and 2 produced as described above was particularly tested for their openability, suitability for taking out the contents, and resealability with the zippers. bottom.

The packaging of the paper container 90 with a zipper according to Examples 1 to 15 has a notch 77 and an easy-opening processing line (perforation line) 51 provided on the upper part of the upper stacking plate 34 and the side plate 41 at the top as opening means. As a result, the upper seal portion 53 was easily cut off, and the chuck tape 61 was exposed.

In the paper container 90 with a chuck of Examples 1 to 6, the opening gripping allowance 57 of the opened opening 56 for drawing out is then gripped and pulled apart from each other, thereby facilitating the fitting of the chuck tape 61. I was able to dissociate.
Then, the swing-out opening 56 at the upper part of the package of the paper container 90 with a zipper opens over almost the entire width of the paper container 90 with a zipper.

Next, the sharp opening wire 19 was folded in a valley fold when viewed from the outside of the paper container 90 with a chuck, and the sharp opening 58 was provided in the drawing opening 56.

Salt is injected into a table bottle (mouth inner diameter 40 mm) from the sharp opening 58 of the drawing opening 56 by tilting the front wall plate 31b of the paper container 90 with a chuck so that it is downward. rice field.
At that time, the salt was injected without being spilled.

In the paper container 90 with a chuck of the seventh embodiment, the opening gripping allowance 57 of the opened opening 56 for drawing out is then gripped and pulled apart from each other, whereby the fitting of the chuck tape 61 is easily dissociated. did it.
Since the opening 56 for swinging out at the upper part of the package of the paper container 90 with a chuck is limited by the opening limiting portion 54, the opening 56 for swinging out is limited to an appropriate size.

In the paper container 90 with a chuck of Examples 8 to 10, the opening gripping allowance 57 of the opened drawing opening 56 is then gripped and pulled apart from each other, thereby facilitating the fitting of the chuck tape 61. I was able to dissociate.
Since the opening 56 for swinging out at the upper part of the package of the paper container 90 with a chuck is limited by the opening limiting portion 54, the opening 56 for swinging out is limited to an appropriate size.

Next, the sharp opening wire 19 was folded in a valley fold when viewed from the outside of the paper container 90 with a chuck, and the sharp opening 58 was provided in the drawing opening 56.

Salt is injected into a table bottle (mouth inner diameter 30 mm) from the sharp opening 58 of the drawing opening 56 by tilting the front wall plate 31b of the paper container 90 with a chuck so that it is downward. rice field.
At that time, the salt was injected without being spilled.

In the paper container 90 with a chuck of Examples 11 and 12, the opening gripping allowance 57 of the opened opening 56 for drawing out is then gripped and pulled apart from each other, thereby facilitating the fitting of the chuck tape 61. I was able to dissociate.
The swing-out opening 56 at the upper part of the package of the paper container 90 with a zipper opens over almost the entire width of the paper container 90 with a zipper.

Further, when the swing-out opening 56 is opened, the upper overlapping 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 39. Deformation could be performed more smoothly by properly bending the opening auxiliary line 55.

Next, the sharp opening wire 19 was folded in a valley fold when viewed from the outside of the paper container 90 with a chuck, and the sharp opening 58 was provided in the drawing opening 56.

Salt is injected into a table bottle (mouth inner diameter 40 mm) from the sharp opening 58 of the drawing opening 56 by tilting the front wall plate 31b of the paper container 90 with a chuck so that it is downward. rice field.
At that time, the salt was injected without being spilled.

In the paper container 90 with a chuck of Examples 13 to 15, the opening gripping allowance 57 of the opened drawing opening 56 is then gripped and pulled apart from each other, thereby facilitating the fitting of the chuck tape 61. I was able to dissociate.
Since the opening 56 for swinging out at the upper part of the package of the paper container 90 with a chuck is limited by the opening limiting portion 54, the opening 56 for swinging out is limited to an appropriate size.

Further, when the swing-out opening 56 is opened, the deformation of the top plate 33 and / or the protrusion (ear) allowance 39 and / or the side plate 41 of the top is caused by the opening auxiliary line 55. By bending properly, it was able to deform more smoothly.

Next, the sharp opening wire 19 was folded in a valley fold when viewed from the outside of the paper container 90 with a chuck, and the sharp opening 58 was provided in the drawing opening 56.

Salt is injected into a table bottle (mouth inner diameter 30 mm) from the sharp opening 58 of the drawing opening 56 by tilting the front wall plate 31b of the paper container 90 with a chuck so that it is downward. rice field.
At that time, the salt was injected without being spilled.

After taking out a part of the salt, the chuck can be easily refitted with the packaging of the paper container 90 with the chuck of Examples 1 to 15 to reseal the paper container, and the remaining salt can be appropriately used. I was able to save it to.

On the other hand, the packaging of the paper container 80 with a zipper of Comparative Examples 1 and 2 has a notch 877 and an easy-opening processing line provided as an opening means on the upper portion of the upper stacking plate 834 and the side plate 843 of the upper stacking plate 834. The upper edge was easily cut off by (perforation line of sight) 851, and the chuck tape 861 was exposed.

Next, the opened opening for swinging 856 was grasped and both were pulled apart from each other, so that the fitting of the chuck tape 861 could be easily dissociated.
Then, the swing-out opening 856 at the upper part of the package of the paper container 80 with a zipper opens over almost the entire width of the paper container 80 with a zipper.

The front side wall plate 831b of the paper container 80 with a zipper of Comparative Examples 1 and 2 was tilted so as to be a bottom side, and salt was injected into a table bottle (mouth inner diameter 40 mm).

Since the chucked paper containers 80 of Comparative Examples 1 and 2 do not have a sharp opening, the front blank plate 81b of the drawing opening 856 has a curved curve with a large curvature. Therefore, when the salt passed through the substantially central portion in the width direction of the front side blank plate 81b, the width was wider than the inner diameter of the mouth portion of the bottle to be injected, and the salt spilled.

Further, in the paper container 90 with a chuck of Examples 1 to 15, the mass ratio of the paper to the total mass of the paper container is about 60 mass%, which sufficiently satisfies the standard of 51 mass% or more as a paper container. Met.
