Description

  The present invention relates to shampoos and rinses that are hair washing related products, bathing agents, laundry softeners and laundry detergents that are laundry related products, and kitchen detergents, as well as sauces, soups, dressing sauces, pasta sauces in edible relations, The present invention relates to a packaging container that can contain instant coffee powder, dashi stock, etc. as contents and is mainly used for refilling, and a package using the packaging container.

  Conventionally, for the purpose of environmental conservation and resource saving, refilled containers have been circulated as products in order to repeatedly use empty bottle containers, and refillable packaging containers for storing refillable containers have been provided. Widely used. As a packaging container for refilling, a packaging container called a flexible standing pouch made of a self-supporting plastic film has been widely used. These refillable standing pouch-type packaging containers are provided with spout portions that project in a bowl-like shape at the upper end corner and upper end central part so that transfer to an empty bottle container is easy. It was.

  Other than the above-mentioned standing pouch type, it is a flat pouch-shaped packaging container that has an upper surface film and a lower surface film overlapped and has a periphery as a seal portion, and is bent at the center of the container when necessary and formed at one end of the folding position. There has been proposed a contrivance that allows the contents to be poured out from the spout portion (see Patent Documents 1 and 2).

JP 2004-323077 A Japanese Utility Model Publication No. 05-029942

The above-mentioned standing pouch-type packaging container heat-seals the opposite sides of the front film and the back film, and folds the bottom film between the front film and the back film on the lower side of the container. Heat sealing is performed at the required locations of the opposed front film and back film, and the bottom part is developed so as to separate the lower sides of the front film and back film, thereby forming a satisfiable container bottom. The display effect at the store is good.
However, first, in order to make this container self-supporting in a vertically placed state and to ensure the ease of handling of the container itself when the contents are poured out, a certain degree of waist strength of the film is necessary. There is a limit to reducing the thickness of the film, and there is a limit to reducing the amount of waste that can be discarded. In addition, depending on the shape of the spout part, it is difficult to pour out the contents to be stored. Particularly, when the spout part is narrow and long, the front of the spout part may be cut even if the spout part is cut. The film and the back film are easily bonded to each other, and the spout obtained by cutting may be easily clogged with the contents.

On the other hand, since the packaging container of the said flat pouch form improves the transport efficiency of the container itself, and can reduce the film thickness, it is considered that the container can be reduced in weight.
However, the shape of the package filled with the contents using this flat pouch packaging container will remain a flat container, and if you do not use a separate paper box, store products will stand upright. They cannot be placed side by side on the display shelf and must be stacked. Therefore, the eye catching effect as a product at the time of store display becomes extremely poor, and a great problem arises in stability when a plurality of products are stacked. Furthermore, in a package used for this type of application, it is required to be able to be opened manually so that it does not take time when opened, but in this conventional form, the film overlaps at the spout part by bending. In some cases, it was difficult to open by hand.
For the above reasons, packaging bodies in which the above-described standing pouch-type packaging containers are filled with the contents for refilling are in circulation.

In the case of a flat pouch-type packaging container, the present inventor has the advantage that the packaging container itself has good transport efficiency, the film can be thinned and the pouch is easy to reduce, and the container is easy to handle when used as a package. The film can be selected to ensure the thickness, and the contents can be smoothly poured out by folding it in half and cutting the spout to form an open spout. Focused on.
Then, this invention makes it a subject to make it easy to perform the cutting | disconnection of a spout part by manual operation, and it aims at providing the packaging body which can be folded in half which is excellent in unsealability and is easy to pour out the contents. Is.

(Invention according to Claim 1)
The present invention has been made in consideration of the above-mentioned problems, and the upper bent portion of the film is formed by overlapping flexible films and bending each of the bent positions upward so that they are outside in the bent state. In contrast, the lower bent portion of the other film that is the inner side in the folded state is arranged away from the lower side of the container, and the left and right sides of the outer film and the inner film are opposed to each other. An outer film side having a seal portion and having a seal portion on a lower side where the outer film and the inner film face each other and facing above the position of the lower bent portion A seal part is formed on the side, and a storage part made up of an outer film and an inner film is folded in two at the folded part where the upper folding position and the lower bending part are opposed to each other. The accommodating portion by opening the bending at the position of the bend is a packaging container extendable clamshell to the container vertically,
On the one end side of the bent portion, a spout portion is provided which is surrounded by the end peripheral portion of the upper bent portion and the end peripheral portion of the lower bent portion and is convex toward the container side,
In the lower part around the vertical section of the spout part, a seal part having a shape that wraps around the spout part projecting tip side to the spout part lower side is arranged,
The peripheral portion of the end portion of the lower bent portion extending from the height position of the upper edge of the seal portion disposed at the lower portion of the spout portion to the height position of the lower bent portion has a width in the folding height direction. The lower seal portion is lower than a height position that is 1/3 of the height from the lower edge of the seal portion formed at the upper portion of the outlet portion to the upper edge of the seal portion disposed at the lower portion of the spout portion. It is considered as a range to a position close to the upper edge of the lower bend, and the peripheral portion of the end of the lower bend can be expanded in the direction in which the lower bend opens.
The outer film in the spout portion is provided with a planned opening line portion formed by subjecting the outer film to easy opening,
The planned opening line part is a first line part from the position of the upper bending part on the outer film toward the height position corresponding to the lower bending part, and the protruding line side of the spout part from the first line part. It consists of a second line portion that extends along the upper edge of the lower seal portion.
The first line portion is inclined from the position of the upper bent portion of the spout portion to the protruding direction side of the spout portion,
The peripheral portion of the lower bent portion that can be expanded in the opening direction is positioned in the spout portion, and the lower bent portion at the spout portion cut at the planned opening portion can be expanded. The above-mentioned problem is solved by providing a two-fold packaging container characterized by the above.

(Invention according to Claim 2 )
In another aspect of the invention, the contents filled in the folded packaging container and stored in the storage portion are a liquid detergent composition or a disinfectant composition. A folded package is provided to solve the above problems.

(Effect of the invention according to claim 1)
According to the two-fold packaging container of the present invention, the peripheral portion of the end portion of the lower bending portion extending from the height position of the upper edge of the sealing portion disposed at the lower portion of the spout portion to the height position of the lower bending portion is Since the lower bent portion can be expanded in the opening direction, the spout portion is cut in the package filled with the contents obtained from the packaging container, and when the contents are poured out, The peripheral part of the end of the lower bent part is easily developed and the spout is opened greatly. Therefore, it is possible to obtain a package in which the contents are smoothly poured out from the present packaging container.
In addition, the width in the folding height direction of the peripheral portion of the end portion on the side of the lower bent portion at the spout portion is arranged from the lower edge of the seal portion formed at the upper portion of the spout portion to the lower portion of the spout portion. Since this is a range that is lower than the height position that is 1/3 of the height to the upper edge of the seal portion and close to the upper edge of the lower seal portion, the folding portion itself is a spout. It is only located in a state of being slightly folded toward the inside of the part. That is, the degree of overlap between the peripheral portion of the end portion of the upper bent portion and the folded portion is small, and it is possible to maintain a good hand cutting property when manually cutting the spout portion without impairing the pouring property. Excellent effects such as being able to do it.
Furthermore, since the planned opening line portion is inclined toward the spout portion side, the portion that is easy to cut at the spout portion that overlaps only the peripheral portion at the end of the upper bent portion is the planned opening line. It can be ensured as a long distance in the part, and it becomes easy to give momentum to the progress of the tear when tearing from the upper bent part side. Therefore, from this point as well, the hand cutting performance is improved and the diameter of the spout obtained by cutting becomes large.
The bi-fold packaging container of the present invention has a compact form and can reduce the weight of the film to be formed, so that the transport efficiency in the distribution process is good.
Moreover, in the two-fold package obtained from the two-fold packaging container of the present invention, when the stored item is poured out by cutting the spout portion, the two spouts are folded into the opened spout portion. Since the contents flow in from the storage section divided into two, the flow rate from the spout portion is large, and the content is well poured out. Furthermore, even when the film is thinned, the overall shape of the folded package is difficult to collapse. Even if it is held by hand, it does not lose its shape, and the handling (ease of handling) during pouring is easy. Improve.

  Further, in the bi-fold packaging container of the present invention, the shape is different from that of the conventional standing pouch described above, and the two storage portions are connected in a triangular shape with the downward opening, with the folding position to be configured as the upper end. The container is naturally self-supporting, and the film constituting the pouch can be thinned, so that the pouch can be reduced in weight.

In addition, the outer film in the spout portion is provided with an expected opening line portion formed by subjecting the outer film to an easy opening process, and the opening opening line portion is an upper bent portion of the outer film. A first line portion extending from a position to a height position corresponding to the lower bent portion, and a first line portion extending from the first line portion toward the protruding tip side of the spout portion along the upper edge of the lower seal portion. Since the first wire portion is inclined from the position of the upper bent portion of the spout portion to the protruding direction side of the spout portion , as described above, the upper bent portion side of the spout portion rather easily advanced with the momentum of the tear extending from the beginning of the cutting from, hand cutting of the spout is improved.

Moreover, since the said opening expected line part is an easy-opening process to the outer film which is an edge part peripheral part of an upper bending part, the hand cutting property of a spout part will become still better. There is an effect.

(Effect of the invention according to claim 2 )
According to invention of Claim 2, since the contents accommodated in the folded package are a liquid detergent composition or a disinfectant composition, transfer of a liquid detergent composition or a disinfectant composition A package that can be easily processed is obtained.

It is explanatory drawing shown in the state which looked at an example of the bifold packaging container which concerns on this invention from the film surface side. It is explanatory drawing which shows an example of a folding container similarly in a longitudinal cross section. It is explanatory drawing which shows the form which opened an example vertically. It is explanatory drawing which shows the state which opened the example similarly lengthwise with a longitudinal cross-section. It is explanatory drawing which shows the open spout part in the longitudinal cross-section.

Next, the present invention will be described in detail based on the embodiment shown in FIGS.
In the figure, reference numeral 1 denotes a two-fold packaging container. The packaging container 1 is formed by laminating a film 2 and a film 3 made of flexible synthetic resin packaging materials having the same single-layer structure or the same laminated structure. The film 2 is bent in such a manner that the respective folding positions are convex upward, and is bent into a substantially triangular shape (substantially Λ-shaped) that opens downward as shown in the figure. The seal portion 4 is formed by using a heat seal method at the sides facing the inner film 3. Of the pair of seal portions 4 that are the lower portion of the container in this folded form, one seal portion 4 has the same unit as the films 2 and 3 between the film 2 and the film 3. The film 5 having a layer structure or different single layer structure, or the same or different laminated structure is folded, and the opposite sides of the film 2 and the film 5, and the opposite sides of the film 3 and the film 5. Are heat-sealed so that they can be opened by opening between the films 2 and 3.

  Moreover, in this packaging container 1, as shown in figure, the upper bending part 2a of the outer film 2 and the lower bending part 3a of the inner film 3 do not overlap with each other, and the upper bending part 2a On the other hand, the lower bending portion 3a is arranged away from the lower side of the container. And since the upper bending part 2a and the lower bending part 3a are separated up and down, the outer films 2 are opposed to each other above the position of the lower bending part 3a. In each of the sides on both sides of the film, the film 2 is heat-sealed to form a seal portion 4, and the seal portion 4 on the side of the container side between the film 2 and the film 3, and this downward bending A seal formed by heat-sealing the films 2 to each other along the bent portion of the outer film 2 while being continuous with the seal portion 4 (the seal portion between the sides of the film 2) above the portion 3a. The part 4 is provided over the container width direction, and the seal part 4 extending in the container width direction is continuous with the seal part 4 on the side. In this way, the upper bent portion 2a for folding the outer films 2 together is configured as a seal portion 4 made of heat seal at the upper portion of the two-fold packaging container 1.

  The storage unit 6 formed by placing the two films 2 and 3 so as to be opposed to each other and arranging the film 5 at the lower part of one container has a bent part 7 in which the upper bent part 2a and the lower bent position 3a are opposed to each other. However, they are in communication with each other with the bent portion 7 in between.

As shown in the drawing, one side in the longitudinal direction of the bent portion 7 on the container upper side, that is, one side in the container width direction is convex toward the side of the container so as to be continuous with the portion of the bent portion 7. The spout 8 is located. The shape which becomes the convex toward the container side of the spout part 8 is such that the seal part 4 on the side of the spout part 8 side of each of the storage parts 6 divided into two is the center of the storage part 6. As shown in the figure, the seal portion 4 on the same side of each of the storage portions 6 has a storage portion from a lower position than the lower bent portion 3a. 6 is provided with a curved seal portion 9 having a curved shape so as to be convex toward the center side. Thus, since the curved seal portion 9 has a shape that protrudes inward from the lower position of the lower bent portion 3a toward the inside of the storage portion 6 below the spout portion 8, the spout portion 8 The lower seal portion 4 is formed by an upper seal portion of the curved seal portion 9.

In the present embodiment, at the lower part of the spout part 8, the curved seal part 9 is shaped so as to protrude toward the center of the storage part 6, and the upper seal part 4 of each of the curved seal parts 9 is poured. It is made to be located below the outlet portion 8. That is, the lower position in the (cross-section around a direction perpendicular to the longitudinal direction of the bent portion 7) vertical cross section around the spout portion 8, the sealing portion 4 consisting of songs seal portion 9 is arranged. Further, on the protruding end side of the spout 8, a seal part 4 made of heat seal between the sides of the outer film 2 is arranged, and the two seal parts 4 made of the curved seal part 9 are arranged on the seal part 4. Is continuous. Further, a seal portion 4 that is an upper bent portion 2a is disposed at the upper portion of the spout portion 8, and the seal portion 4 at the upper portion of the spout portion is continuous with the seal portion 4 at the front end side of the spout portion. .

As described above, the bi-fold packaging container 1 is folded in half into a substantially triangular shape with an open bottom, but is folded so that the seal portion 4 that does not fold the bottom film at the bottom of the container is on top. By opening the bend at the position of the bend portion, the storage portion can be extended in the vertical direction of the container to form a vertically long container shape. As shown in the drawing, the packaging container 1 is elongated vertically and extended in the vertical direction of the container so that the storage part 6 divided into two via the bent part 7 forms a single storage space. Then, the inner film 3 with the lower bent portion 3a opened and the outer film 2 opened by folding from the crease 10 at the height corresponding to the lower bent portion 3a face each other, and the film 5 on the bottom surface unfolds. It becomes a standing pouch type shape that forms a well-seatable container bottom.
The opening of the outer film 2 in the present embodiment is opened as follows. That is, in the outer film 2 in the form of a double fold, in the region from the upper bent portion 2a to the seal portion 4 at the bottom of the container, the crease 10 is put in advance at a position corresponding to the lower bent portion 3a. The region corresponding to the bent portion 7 and the portion of the upper bent portion 2a rotate downward in the container so that the region from the upper bent portion 2a to the seal portion 4 with no bottom film interposed is formed. Waking up causes the outer film 2 to open. The portion corresponding to the bent portion 7 of the outer film 2 and the portion of the upper bent portion 2a are provided so as to rotate toward the bottom of the container and overlap the region extending over the bottom of the container. The form of the pouch is kept intact.

  Since the folded packaging container 1 can be in the form of a standing pouch as described above, for example, when the standing pouch is opened at the position of the bent portion 7, it is positioned on the side opposite to the container bottom. An opening between the opposite sides of the outer film 2 and the inner film 3 at the upper part of the container is made to be an unsealed filling port, and after the contents are filled from this filling port, the outer film 2 and the inner film By heat-sealing the sides of the upper part of the container opposite to the film 3, a standing pouch-type package 11 is obtained, and this is bent at the position of the lower bending portion 3 a in the inner film 3. The folded portion 7 rises as the upper side of the container, and the spout 8 is on the upper side of the container in the folded package, on one side. Only it will be positioned in a state in which a convex. This bi-fold package has a substantially triangular shape that opens downward, so that it can be satisfactorily satisfactorily, and can be displayed as a product in a stable state even when placed vertically on a display shelf such as a retail store.

As described above, the spout portion 8 is in one end side in a state of being continuous with the bent portion 7, and the end peripheral portion 12 of the upper bent portion 2 a in the outer film 2 and the lower bent portion 3 a in the inner film 3. And an end peripheral portion 13. Then, in the end peripheral portion 13, Note fold height width 14 over to the height position of the lower bent portion 3 a from the height position of the upper edge of the seal portion 4 of the lower part of the outlet portion 8, Lower than the height position that is 1/3 of the height from the lower edge of the seal part 4 (upper bending part 2a) formed at the upper part of the spout part 8 to the upper edge of the lower seal part 4, The range extends to a position close to the upper edge of the lower seal portion 4. Thus, by setting the width 14 of the folded portion 15 (folded end peripheral portion 13) within the above-described range, the folded portion 15 and the end peripheral portion 12 of the upper bent portion 2a in the spout portion 8 are provided. When the spout portion described later is cut, it becomes difficult to receive resistance by the operation of tearing the end peripheral portion 12 of the upper bending portion 2a by hand, and the upper bending portion 2a side can be easily and manually operated. The spout portion can be cut from. Furthermore, if the spout portion 8 is cut and opened with a width of 2/3 or more from the upper bent portion 2a in the vertical width direction of the spout portion, there is no problem in the pouring property, and there is a problem in the hand cutting property. Does not occur.
Further, the width 14 in the folding height direction of the end peripheral portion 13 of the lower bent portion 3a which is the folded portion 15 is from the lower edge of the upper bent portion 2a of the spout portion 8 to the upper edge of the lower seal portion 4. Is lower than the height position that is 1/3 of the height of the lower seal portion 4 and close to the upper edge of the lower seal portion 4, so that the lower bent portion 3a can be expanded in the opening direction. Yes. FIG. 5 schematically shows the shape in the longitudinal cross-sectional direction when the contents pass through the cut out spout 8 and the folded down bent portion 3a can be developed. When the object passes through the portion 8, it tries to push open the end peripheral portion 12 which is the bent shape of the upper bent portion 2 a, but the end peripheral portion 13 of the lower lower bent portion 3 a is opened. now end peripheral portion 12 of the upper bending portion 2a is easily opened, thus Note spout obtained by cutting the outlet portion becomes what is wide spread in the longitudinal sectional direction, pouring of contained object is Become smooth. Of course, since the end peripheral portion 13 of the lower bent portion 3a can be developed, the bi-fold packaging container 1 and the bi-fold packaging body 11 filled with the contents are vertically opened to form a standing pouch. Even in this case, the pair of seal portions 4 below the spout portion and the range up to the lower end position of the seal portion 4 on the front end side of the spout portion where the pair of seal portions 4 meet open without resistance. It will fall down properly and will not damage the appearance of the container.
In the above embodiment, the packaging container has been described as having a bottom film and can be in the form of a standing pouch, but the present invention is not limited to this example. It may be in the form of a flat pouch provided with a storage portion 6 formed by overlapping an outer film and an inner film.

  In order to improve the hand cutting property when the spout 8 is cut, the width of the seal portion 4 at the upper bent portion 2a in the height direction of the seal portion on the spout portion 8 side is increased. A knob auxiliary portion 16 is formed to increase the area holding the tip side of the outlet portion 8, and the width in the height direction of the seal portion other than the knob auxiliary portion 16 at the upper bent portion 2a is reduced. In addition, an acute notch 17 is provided at the end opposite to the tip end side of the spout portion of the knob auxiliary portion 16 to form a notch shape that can easily form the starting end of the tear.

Furthermore, an opening planned line portion 18 formed by easy opening processing such as laser irradiation and half-cut is provided at the end peripheral portion 12 of the upper bent portion 2a of the spout portion 8 with the cutout portion 17 as an upper end. It is provided at a position overlapping the two folded surfaces of the peripheral portion 12.
As shown in FIG. 1 , the planned opening line portion 18 includes a first line portion 18 a that reaches a height position corresponding to the lower bent portion 3 a from the notch portion 17, and a spout from the first line portion 18 a. The second line portion 18b extends to the protruding end edge of the spout portion along the upper edge of the seal portion 4 toward the protruding tip side of the portion 8, and the first line portion 18a It inclines to the protrusion direction side of the spout part 8 from the position. Thus, since the opening opening line part 18 inclines from the position of the notch part 17 to the protrusion direction side of the spout part 8, the tear produced from the notch part 17 is an upper bending where the film 2 is overlapped double. The end of the upper bent portion 2a without resistance even at the point where the folding portion 15 is positioned and the four layers of the film are located by increasing the distance traveled through the peripheral portion 12 of the end portion of the portion 2a and the momentum to advance the tear. Proceed by tearing the peripheral portion 12. Therefore, the hand cutting ability is good. Since the scheduled opening portion 18 is slanted as described above, the spout becomes larger than when the spout portion is cut straight vertically, and a sufficient diameter is required to pour out the contents. as possible out to be secured.

The film used for the two-fold packaging container of the present embodiment is, for example, a laminated structure of (outer layer side) base material layer / adhesive layer / sealant layer (inner layer side), (outer layer side) base material layer / adhesive Layer / intermediate layer / adhesive layer / sealant layer / (inner layer side) layered structure.
For the base material layer, generally used biaxially stretched polypropylene film, biaxially stretched polyester film, biaxially stretched nylon film, moisture-proof cellophane, and the like can be used.

  In addition, a polyurethane-based adhesive is generally used for the adhesive layer. Usually, a two-component type is used in which a main component having a hydroxyl group and a curing agent having an isocyanate group are mixed in two components. The lamination is performed by a known gravure coating method.

  The intermediate layer is provided mainly for imparting gas barrier properties or improving various mechanical strengths, and is composed of a single layer or a multilayer film. As the single layer film, unstretched nylon film, aluminum foil, ethylene / vinyl alcohol copolymer film, vinylidene chloride film, vinyl alcohol film, acrylic film, vinylidene chloride resin coated cellophane, etc. are used. A multilayer film obtained by laminating a single layer film, an inorganic oxide-deposited polyester film, an aluminum-deposited polypropylene film, an aluminum-deposited polypropylene film, or the like is used. Lamination is performed by a known dry lamination method or the like.

  The sealant layer is made of a polyolefin resin or a polyolefin resin film. Examples of the resin include low density polyethylene, medium density polyethylene, linear low density polyethylene, and ethylene / vinyl acetate copolymer. Polypropylene resins such as homopolypropylene, homopolypropylene, propylene / ethylene random copolymer, propylene / ethylene block copolymer, and polypropylene-α-olefin copolymer can be used. Lamination is performed by a known melt extrusion method or dry lamination method. After these films (or resins) are bonded together by dry lamination and a base paper is prepared, a bi-fold packaging container having a filling port may be prepared by a bag making machine.

  Furthermore, it is set in a filling machine in a bi-fold packaging container, filled with the contents in a state of standing pouch form or flat pouch form, and the unsealed filling port part is heat-sealed, thereby standing pouch A package in the form of a flat pouch or a flat pouch is obtained, and this is folded in half from the position of the lower bending portion of the inner film as described above, whereby a package in a double fold is obtained.

The relationship between the hand cutting property and the pouring property was confirmed by changing the width (14) of the folded portion to produce a folded package. The size of the pouch was 130 mm in width and 110 mm in the folded state, and the height from the lower edge of the upper bent portion to the upper edge of the lower seal portion in the spout portion was 15 mm.
When opening the packaging, fold the packaging container in half and hold the knob auxiliary part on the side of the upper bent part of the spouted part with one finger, and hold the vicinity of the spout part with the other hand Then, it was cut by hand so as to block the spout, and the pouring property was observed. The results are shown in Table 1. As shown in Table 1, it was confirmed that when the width of the folded portion was 0.5 to 5 mm, particularly 0.5 to 3 mm, both the hand cutting property and the pouring property were good.
