Description

The present invention relates to a paper container with a chuck, and particularly in the field of a paper container having a three-dimensional shape and having self-supporting property, the opening degree of the drawing opening can be adjusted, and the amount of drawing out of the contents can be adjusted. Regarding easy-to-chuck paper containers.

Conventionally, a technique such as Patent Document 1 has been disclosed as a paper container with a zipper. 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 closed when the contents are taken out.
With the above technique, it is possible to protect the contents and prevent the contents from spilling when the paper container falls. Moreover, 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 the conventional chucked paper container 80, FIG. 2 is a perspective view of the prior art chucked paper container 80, FIG. 3 is a plan view, and FIG. 4 is a top portion. The perspective view of the state in which is opened is shown.

It shall indicate the sword and the bottom sword. The same applies to the paper container 90 with a chuck of the present invention.
In addition, the reference numerals used when explaining the prior art are in the 80s or 800s in order to distinguish them from the present invention.
Further, the subscript a of the code indicates an element of the back side portion of the paper container 80 with a chuck, and the subscript b indicates an element of the front side 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 is opened and the contents are swung out, the top surface protruding portion (ear portion) 874 is first removed from the body portion 872. Next, after the easy-opening processing line 851 is cut, the chuck tape 861 is opened and the drawing opening 856 is opened.
Then, the contents are drawn out by lifting and tilting the paper container 80 with a chuck.

However, as will be described later, the drawing opening 856 does not have an opening limiting portion that limits the opening of the top portion 871, and as shown in FIG. 4, the opening is opened over substantially the entire surface of the chucked paper container 80 in the transverse direction. Therefore, in response to a request for a small amount of drawing, there is a risk that a large amount of the material will be unintentionally drawn out more than a desired amount.

It should be noted that 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 78 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 blank plate 10a cannot be seen, but when viewed through, the front blank plate 10b has the same shape.

In FIG. 6, the back blank plate 10a and the front blank plate 10b overlap each other, and each component has the same positional relationship when viewed through the drawing within the range of manufacturing variation. My notation and subscripts may be omitted in the explanation.

The upper superposition plate 34 and the side plate 41 at the top of the front side are provided with an upper seal portion 53 as a sealing means in the transverse direction at a predetermined position where the above-mentioned two blank plates overlap each other. , The chuck tape joint portion 52 is provided in order 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 stacking plate 34 and the side plate 41 of the front side plate 41, 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 composed of a first easy-opening processing line 511, a second easy-opening processing line 512, and a third easy-opening processing line 513.
However, in the present embodiment, it is not always necessary to have the above-mentioned easy-opening processed line configuration, and the opening limiting portion 54 described below may be appropriately provided, and one embodiment is illustrated here.

In the present invention, when a small amount of the contents filled in the chucked paper container 90 is shaken out, the opening degree of the drawing opening 56 of the top portion 71 of the chucked paper container 90 can be adjusted, and the amount of the contents drawn out can be adjusted. It is easy to adjust the amount of. Therefore, an opening limiting portion 54 for adjusting the opening degree is provided.
The opening limiting portion 54 is formed by partially removing the upper sealing portion 53 and leaving a partial portion.

The upper portion of the top portion 71 of the paper container 90 with a chuck is composed of an opening limiting portion 54 and a swing-out opening 56 in the transverse direction, and the direction from the first side edge portion 11 to the second side edge portion 16 (the inside is). An opening limiting portion 54 is provided in the direction of the window).
Further, a swing-out opening 56 is provided in the direction from the second side edge portion 16 to the first side edge portion 11 (inward direction).

The first easy-opening processing line 511 extending from the second side edge portion 16 toward the first side edge portion 11 in the transverse direction, and the first side edge portion of the first easy-opening processing line is the end L1. The laminated sheet 78 of the paper container 90 with a chuck is cut off by the second easy-opening processing line 512 that connects to and reaches the upper edge portion 21. The swing-out opening 56 is formed by partially exposing the chuck tape 61.

Further, the first easy-opening processing line 511 and the third easy-opening processing line 513 are connected at the end L1 of the first side edge portion of the first easy-opening processing line 511, and their connection points. The second easy-opening processing line 512 is branched from the end L1 of the first side edge portion 11 of the first easy-opening processing line 511.

The first easy-opening processing line 511 exists between the upper sealing portion 53 and the chuck tape joint portion 52, and the first easy-opening processing line 511 is cut to cut the upper part of the chuck tape 61. The chuck tape 61 is partially exposed by separating the upper seal portion 53 from the upper superposition plate 34 of the portion and the side plate 412 of the second top portion.

Further, when the second easy-opening processing line 512 is cut, the upper seal portion 53 is cut and reaches the upper edge portion 21, so that the laminated sheet 78 of the paper container 90 with a zipper forming the drawing opening 56 is formed. Sections are cut out.

When the first easy-opening processing line 511 is manually cut by a human, when the first side edge portion 11 of the first easy-opening processing line 511 reaches the edge L1, the direction of the force applied to the cutting is changed. The cutting of the easy-opening processing line 512 can be started. At this time, it is necessary to be careful not to accidentally cut the third easy-opening processing line 513.

The upper seal portion 53 is cut by the first easy-open processing line 511 and the second easy-open processing line 512, which are a part of the easy-open processing line 51, which exist between the upper seal portion 53 and the chuck tape joint portion 52. The remaining portion becomes the opening limiting portion 54.

When the contents are drawn out, the chuck tape 61 is opened, but since the size of the opening is regulated by the opening limiting portion 54, the drawing opening 56 has an appropriate opening condition, and an appropriate amount of the contents is distributed. It is possible to start with.

Further, when the contents are swung out, the swing-out opening 56 is tilted downward, but the opening limiting portion 54 grips the upper overlapping plate 34 and / or the side plate 411 of the first top portion. , Easy to tilt the paper container with zipper.

When the remaining amount of the contents becomes low, the drawing opening 56 may be opened to the full width in order to make it easier to take out the contents. For that purpose, the third easy-opening processing line 513 must be cut from the first side edge portion 11 to at least one of the cut first easy-opening processing line 511 or the second easy-opening processing line 512. Then, the drawing opening 56 may be opened to substantially the entire width.
Further, the third easy-opening processing line 513 may be cut from the first easy-opening processing line 511.

As described above, when it is desired to draw out a small amount, the opening degree of the drawing opening 56 can be reduced, and when the remaining amount is low, the opening degree of the drawing opening 56 can be increased and the contents can be taken out. Therefore, it is possible to obtain a swing-out opening 56 having an opening degree as required.

When an intermittent half-cut line or a straight half-cut line is used for the easy-open 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.

Further, although not shown, only the first easy-opening processing line 511 exists, and the first easy-opening processing line 511 crosses the upper seal portion 53 from the second side edge portion 16 and reaches the upper edge portion 21. May be good.

(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 371 and 372 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 chuck 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 described above, the laminated sheet 78 used for the blank plate 93 is a laminated sheet 78 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 as the innermost layer and / or the outermost layer thereof. Although it is used, the intermediate layer may be provided with a water vapor, oxygen, other gas barrier layer, a strength improving layer, or the like, if necessary.

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 between the outermost heat-adhesive resin layer and the paper base material layer.

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, in addition to low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE), medium-density polyethylene (MDPE) and high-density 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 copolymers (EMAA), ethylene / methyl acrylate copolymers (EMA), ethylene / ethyl acrylate copolymers (EEA), ionomers, polypropylene and its copolymers, polyester resins, 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 78, the gas barrier layer is a biaxially stretched polyethylene terephthalate film (hereinafter, referred to as a biaxially stretched polyethylene terephthalate film) in which a metal foil such as an aluminum foil, a metal such as aluminum, silica or alumina or an inorganic oxide is stretched. A vapor-deposited film deposited to a thickness of 20 to 100 nm can be used as a base film such as PET film), biaxially stretched nylon film (hereinafter, ON film), and 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.

Such a gas barrier layer is usually preferably laminated on the inner surface of the paper base material layer of the intermediate layer because its 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.

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.

A case where a crushed portion for facilitating bending is provided in the bent portion of the chuck tape 61 will be described. Although not shown in the figure, the chuck tape 61 heat-sealed at the chuck tape joint 52 has a size of about 2 mm at positions orthogonal to the second vertical bending line 13 and the third vertical bending line 14, respectively. The outer surface of the laminated sheet 78 of the paper container 90 with a chuck is pressed by a hot press or the like to crush the chuck tape 61 and deformed so as to reduce the thickness, whereby the crushed portion can be provided.

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 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 paper seal allowances 371 and 372, 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 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 includes 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.

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 first side edge portions 11 are heat-sealed with each other, and the second side edge portions 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 second side edge portion 16 of the first easy-opening processing line 511, and the bottom is an intermediate stage chuck having a folded shape in which the sealing allowance 38 opens unsealed. A paper container (flat state) 91 is manufactured.

(Making a paper container with a zipper in the intermediate stage (boxing state))
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 superposition plate 34 is left, and the top plate 33 of the lower side thereof is first. The upper stacking 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.

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 horizontal cross section, and an intermediate stage chuck in which the bottom portion 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 superposition 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 the paper container 90 with a chuck made of a flexible laminated sheet 78 mainly composed of paper is used. 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 protruding from both the left and right sides (the top 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). 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.

The opening of the end portion of the opening 56 for swinging out the first side edge portion 11 of the above is suppressed by the opening limiting portion 54. The opening limiting portion 54 is a portion left after the upper seal portion 53 is cut by the first easy-opening processing line 511 and the second easy-opening processing line 512.

When the top portion 871 is opened in the conventional paper container 80 with a chuck having no opening limiting portion, since the opening limiting portion does not exist, the chuck tape 61 has a sealing allowance on one side edge portion as shown in FIG. The other side edge is opened from 836 to the seal allowance 836 over almost the entire width.

FIG. 12A shows the end portion of the upper ridge when the opened paper container 80 with a chuck of the prior art is viewed from above. The drawing opening 856 for drawing out the contents has a large opening over substantially the entire width of the paper container 80 with a chuck, and it is difficult to control when drawing out a small amount of contents, and a large amount is unintentionally drawn out. There is a risk that it will end up.

On the other hand, FIG. 12 (b) shows the end portion of the upper ridge when the opened paper container 90 with a chuck of the present invention is viewed from above. The opening 56 for drawing through which the contents pass when the contents are drawn is a region in which the opening limiting portion 54 is removed from the entire width of the paper container 90 with a chuck, and when a small amount of the contents are drawn out. Is easy to control and the desired capacity can be drawn out.

Further, the method of producing the blank plate 93 and the like have mainly described the front side blank plate 10b, but the back side blank plate 10a has the same shape and has symmetrical upper edges 21a and 21b, respectively. Since the lines are line-symmetrical and the manufacturing method is the same, the description of the backside blank plate 10a is omitted.

Further, the description of the present embodiment has described an example in which the left side has an opening limiting portion 54 and the right side has an opening 56 for swinging out. However, without being bound by this example, the shape may be inverted on the left and right. The right side may have an opening limiting portion 54, and the left side may have an opening 56 for swinging out. The same applies to each embodiment described below.

In Comparative Example 1, the paper container 80 with a zipper shown in FIG. 2 was produced using one blank plate 81 shown in FIG.

In Comparative Example 1, first, the blank plate 81 is bent along the intermediate horizontal bending line 821, and then the front side blank plate 811b (the wall plate 831b is present) and the back side blank plate 811a (the wall plate 831a is present). The inner surfaces of (wa) were overlapped.

In addition, the shape of the easy-open processing line 851 was different, and the shape, material, processing method, and the like of the portion other than the top portion 871 were the same as those in the first embodiment.

≪Evaluation≫
100 paper containers with zippers of Examples 1 to 10 and Comparative Example 1 were prepared.
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 invention in which two blank plates 10a and 10b are joined to produce 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-to-open processing line (perforation line) 851 as in the above.
Therefore, in the paper container 90 with a chuck of the present invention, 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 and Comparative Example 1 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 is bent into the bottom plate 35, and heats to the front bottom plate 35b and / or the front bottom plate seal allowance 38b. After being sealed, the packaging of the paper container 90 with a chuck having a substantially rectangular parallelepiped shape of Examples 1 to 10 and Comparative Example 1 was completed.

Further, the packages of the paper containers 90 with a zipper of Examples 1 to 10 and Comparative Example 1 produced as described above were particularly tested for their openability, aptitude for taking out the contents, and resealability with a zipper.

The package of the paper container 90 with a chuck of Examples 1 to 10 has a notch 77 provided as an opening means on the upper stacking plate 34 and the side plate 41 of the top portion and a first easy-opening processing line (perforation line). ) 511 and / or the second easy-opening processing line 512 (perforation line) easily cuts off the second side edge portion 16 of the upper seal portion 53, and the opening limiting portion 54 is formed in an appropriate size. The opening 56 for swinging out could be formed.

Next, the opening gripping allowance 57 of the opened swing-out 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 opening 56 for drawing out at the upper part of the package of the paper container 90 with a zipper was opened over a desired appropriate width, and the flour filled inside could be drawn out in a desired amount.

Further, after taking out a part of the flour, the chuck can be easily refitted with the packaging of the paper container 90 with a chuck of Examples 1 to 10 to reseal the paper container, and the remaining flour can be resealed. Was able to be saved properly.

Further, when most of the wheat flour is used and the remaining amount is low, the opening limiting portion 54 is cut off by opening the third easy-opening processing line 513, and the top portion 71 of the paper container 90 with a chuck is omitted. It opened all over and the wheat could be taken out without waste.

On the other hand, when the easy-opening processing line 851 of the paper container 80 with a zipper of Comparative Example 1 was cut, the top portion 871 was fully opened. When the flour was sprinkled in that state, it was difficult to control the amount of sprinkling, and a larger amount than the desired amount was sprinkled.

Further, in the paper containers 90 with chucks of Examples 1 to 10, 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. there were.
