Description

The present invention relates to a pouch whose contents made of powder or granules are sealed, and from which the contents can be taken out in two ways. One of the methods for taking it out is to shake out the contents consisting of powder and granules little by little. Another method is to remove a large amount of the contents, for example, the entire amount at once.

Seasonings made of powder such as pepper and shichimi chili pepper are sold in rigid bottles. The inner lid of the bottle is provided with a large number of dispensing holes, and by shaking the bottle, the contents can be taken out little by little.

On the other hand, there are also known pouches in which a flexible pouch is used instead of a rigid bottle to contain the contents consisting of powder and granules, and the contents can be taken out in two ways ( Patent Document 1).

FIG. 3(a) is a front view showing this pouch 200, and FIG. 3(b) is a schematic diagram for explaining the vicinity of the outlet. This pouch 200 has a front side film 10 and a back side film 20 stacked one on top of the other, and the contents are hermetically sealed by sealing them together at their peripheries. In the figure, a indicates the left seal line, b indicates the right seal line, c indicates the lower seal line, and d indicates the upper seal line. Directly below the upper seal line d, a planned cutting line e is provided. By cutting the pouch 200 along this planned cutting line e, a take-out opening is formed.

In this pouch 200, in addition to the front side film 10 and the back side film 20, an intermediate film 30 is used. Note that the widths of the front side film 10, the back side film 20, and the intermediate film 30 are equal to each other. Therefore, the front side film 10, the back side film 20, and the intermediate film 30 are integrally sealed at a portion of the left side seal line a and the right side seal line b.

By the way, as shown in FIG. 3(b), the intermediate film 30 is folded in two along a folding line 33 extending in the width direction. A large number of dispensing holes 34 for dispensing the contents are provided around the bending line 33.

Next, among the two areas divided by the bending line 33, the area located on the front side film 10 side is defined as the front side area 31, and the area located on the back side film 20 side is defined as the back side area 32. First, the front side area 31 is It is sealed on the front side film 10. Further, a first opening/closing tape 62 is attached between the front side area 31 and the back side area 32, so that the front side area 31 and the back side area 32 can be opened and closed freely. A second opening/closing tape 63 is also attached between the back side area 32 and the back side film 20, so that the back side area 32 and the back side film 20 can be opened and closed freely.

This pouch 200 is used as shown in FIGS. 4(a) and 4(b). That is, as shown in FIG. 4(a), when the first opening/closing tape 62 is first opened, the contents consisting of powder and granules are taken out little by little through the shake-out hole 34, as shown by the arrow in the figure. be able to.

On the other hand, when the second opening/closing tape 63 is opened as shown in FIG. It is possible to take out a large amount of contents.

In addition, in these FIGS. 4(a) and 4(b), 62 ₁ is a female type articulator that constitutes the first opening/closing tape 62, and ₆₂₂ is a male type articulator that constitutes the first opening/closing tape 62. It shows the ingredients. Similarly, reference numeral ₆₃₁ indicates a female type articulating tool constituting the second opening/closing tape 63, and reference numeral ₆₃₂ indicates a male articulating tool forming the second opening/closing tape 63.

As can be seen from the figure, when a part of the contents is taken out, the pouch 200 can be resealed and stored by closing both the opening/closing tapes 62 and 63.

Patent No. 4446766

By the way, in such a pouch, the first opening/closing tape 62 and the second opening/closing tape 63 are often opened by mistake. For example, if you open the first opening/closing tape 62 and intend to shake out a small amount at a time, but accidentally open the second opening/closing tape 63, a large amount of the contents will be taken out at once.

SUMMARY OF THE INVENTION Therefore, the present invention provides a pouch that seals the contents consisting of powder and granules, and allows the contents to be shaken out little by little or taken out in large quantities at once, and which does not require the wrong removal method. The purpose is to provide pouches.

That is, the invention according to claim 1 is a pouch in which a content made of powder or granules is sealed, and is constructed by sealing a front side film and a back side film to each other at their peripheries, and an upper part of the periphery is opened. In a pouch that forms a take-out opening,
In addition to the front side film and the back side film, it is configured to include an intermediate film and an opening/closing tape,
The intermediate film is folded in half along a folding line, and is arranged with the folding line facing downward and the tips of the two regions separated by the folding line facing upward,
The intermediate film is provided with a hole for discharging the content made of powder and granules,
Of the two regions of the intermediate film, the region located on the front side film side is the front side region, and the region located on the back side film side is the back side region,
The opening/closing tape extends over the entire length of the pouch in the width direction, and is provided with easy-to-break lines between both side edges of the opening/closing tape to make the opening/closing tape easy to break. Of the two areas separated by the easy-to-break line and extending over the entire length of the pouch in the width direction, one area is the front tape-shaped area, and the other area is the back tape-shaped area,
the front side area of the intermediate film is sealed to the front side film, an end of the back side area of the intermediate film is sealed to an end of the back side tape-like area of the closure tape, and an end of the back side area of the intermediate film is sealed to an end of the back side tape-like area of the closure tape; an end portion of which is sealed to the front film;
The pouch is characterized in that a closure part (second closure part) that can be opened and closed is provided between the back side tape-shaped area and the back side film.

The second occluding portion may be composed of a female articulator and a male articulator that are fitted together.

Note that this pouch may be provided with a first closure part that can be opened and closed between the front side tape-like area and the back side film. This first closure part can also be composed of a female articulator and a male articulator that fit together.

Further, the drawing hole may be provided around the bending line.

By tearing the pouch of the present invention at the easy-to-break line of the opening/closing tape, the contents consisting of powder or granules can be taken out little by little through the opening.

In addition, by opening the second closing part and inserting a spoon there, or by tilting the pouch itself, a large amount of the contents can be taken out from between the intermediate film and the back side film. Note that even when the opening/closing tape is broken at the easy-to-break line and the second closing portion is opened, it is possible to similarly take out a large amount.

As described above, by opening the second closing part, a large amount of the contents can be taken out. On the other hand, when shaking out a small amount, the opening/closing tape may be broken at the easy break line without opening the second closed part. Opening the second closing portion and tearing the opening/closing tape at the easy-to-break line are two different actions that cannot be confused with each other, so there is no danger of making a mistake.

Furthermore, after breaking the opening/closing tape, the pouch can be opened by pinching the tape-like area on the front side and a small amount can be shaken out. On the other hand, by pinching and opening the tape-like area on the back side, a large amount can be taken out. Furthermore, since the height of the front side tape-like area and the height of the back side tape-like area are different, there is no possibility of confusing them.

Therefore, it is possible to prevent the user from mistakenly taking out a large amount of paper even though he intended to dispense a small amount, or from accidentally dispensing a small amount of paper even though he intended to dispense a large amount.

In addition, after taking out the contents in this way, in order to seal the remaining contents inside the pouch, it is sufficient to close the first closing part and the second closing part.

The present invention will be described below with reference to the accompanying drawings. FIG. 1 relates to a first embodiment of the present invention, and FIG. 1(a) is a front view showing this pouch 100, and FIG. 1(b) is a schematic diagram for explaining the vicinity of the outlet.

This pouch 100, like the conventional pouch 200, is made by stacking a front side film 10 and a back side film 20, and sealing them together at their peripheries, thereby sealing the contents made of granular material. In the figure, a indicates the left seal line, b indicates the right seal line, c indicates the lower seal line, and d indicates the upper seal line. Directly below the upper seal line d, a planned cutting line e is provided. By cutting the pouch 100 along this planned cutting line e, a take-out opening is formed.

However, this pouch 100 includes, in addition to the front side film 10 and the back side film 20, an intermediate film 30 and an opening/closing tape 40.

Among these, the widths of the front side film 10, the back side film 20, and the intermediate film 30 are equal to each other. Therefore, the front side film 10, the back side film 20, and the intermediate film 30 are integrally sealed at a portion of the left side seal line a and the right side seal line b.

The intermediate film 30 is folded in half along a folding line 33 that extends in the width direction of the pouch 100, that is, from the left side seal line a to the right side seal line b. It is arranged between the back side film 20 and the back side film 20. In the following description, for convenience, of the two areas 31 and 32, the area located on the front film 10 side will be referred to as the front side area 31, and the area located on the back side film 20 side will be referred to as the back side area 32. . Both the front end of the front side region 31 and the end of the back side region 32 face upward, that is, toward the cutting line e.

A large number of dispensing holes 34 for dispensing the contents are provided around the bending line 33.

On the other hand, the opening/closing tape 40 is disposed between the front side film 10 and the back side film 20, and extends over the entire length of the pouch 100 in the width direction, that is, from the left side seal line a to the right side seal line b. It extends all the way. As can be seen from FIG. 1(b), an easy-to-break line 43 is provided between both edges in the longitudinal direction to make the opening/closing tape 40 easy to break. The easy-to-break line 43 may extend from the inner edge of the left seal line a to the inner edge of the right seal line b, or may extend partially there.

This easy-to-break line 43 may be of any type as long as it can be easily broken with fingers. For example, it can be configured with a half-cut line. Alternatively, it can be configured with perforations, but in this case, it is desirable that the contents made of powder or granules cannot pass through the perforations. In addition, it is also possible to provide a large number of fine scratches and use a line formed by a collection thereof as the easy-to-break line 43.

By the way, for convenience of explanation, in the following explanation, one of the two areas that are divided by this easy-to-break line 43 and extend over the entire length in the width direction of the pouch will be referred to as the front tape-shaped area 41. and the other area is referred to as the backside tape-like area 42. As will be described later, in this example, a first closure part 51 is arranged in the front tape-like area 41, and a second closure part 52 is arranged in the back tape-like area 42.

Note that the easy-to-break line 43 does not need to be located exactly at the center of the opening/closing tape 40. By tearing the opening/closing tape 40 along this easy-to-break line 43, the front side tape-like area 41 where the first closing part 51 is arranged and the back side tape-like area 42 where the second closing part 52 is arranged are separated. It is sufficient if a gap is created between the two areas 41 and 42 through which the contents consisting of powder and granules can pass. Note that, in order to make it easier to grasp the back side tape-like area 42 after being broken, it is desirable that the distance between the easy-to-break line 43 and the second closing portion 52 be approximately 10 mm long.

These front side film 10, back side film 20, intermediate film 30, and opening/closing tape 40 are placed in the following relationship. That is, as shown in FIG. 1(b), first, the front side region 31 of the intermediate film 30 is sealed to the front side film 10. Although the entire surface area 31 does not need to be sealed with the front film 10, it is necessary that the entire length of the pouch 100 in the width direction be sealed so that there is no gap between the two films 31, 10. be. For example, it is sufficient that the upper tip edge of the front side region 31 is sealed over the entire length in the width direction.

The ends of said back area 32 of the intermediate film 30 are then sealed to the ends of the back tape-like area 42 of the closure tape 40. In this case as well, the pouch 100 needs to be sealed over its entire length in the width direction so that no gap is created between the back side area 32 and the opening/closing tape 42.

As described above, since the regions 31 and 32 on both sides of the intermediate film 30 are sealed to the front film 10 and the opening/closing tape 40, respectively, the front film 10 and the opening/closing tape 40 are connected to each other via the intermediate film 30. It is connected. The swing-out hole 34 is arranged between the front film 10 and the opening/closing tape 40.

Next, another section of the opening/closing tape 40, ie, the end of the front tape-like section 41, is sealed to the front film 10. In this case, of course, the entire length of the pouch 100 in the width direction must be sealed so that no gap is created between the front tape-like area and the front film 10.

In this way, the front film 10 is sealed to the intermediate film 30, the intermediate film 30 is sealed to the opening/closing tape 40, and the opening/closing tape 40 is sealed. The cross section of the tape 40 forms a closed curve (see FIG. 1(b)).

Next, two closing parts 51 and 52 are arranged on the opening/closing tape 40. The first closing portion 51 closes the space between the front side tape-shaped area 41 and the back side film 20 in an openable and closable manner. Although this first closing part 51 is not essential to the present invention, it is convenient for sealing the pouch 100 and preserving the remaining contents after a small amount of contents have been shaken out from the shakeout hole 34. .

This first closing part 51 is for opening and closing between the front side tape-shaped area 41 and the back side film 20, and is made up of a female articulating tool 51 ₁ and a male articulating tool 51 ₂ that fit together. It is configured. Of course, both of these articulating tools 51 ₁ and 51 ₂ extend over the entire length of the pouch 100 in the width direction.

The female articulating tool 51 ₁ is integrated with and fixed to the front tape-like area 41 of the opening/closing tape 40 , and the male articulating tool 51 ₂ is fixed to the back film 20 . By fitting the female articulating tool 51 ₁ and the male articulating tool 51 ₂ together, the space between the front tape-shaped area 41 and the back film 20 can be closed. On the other hand, by unfitting the two articulating tools 51 ₁ and 51 ₂ , a passage through which the contents pass can be formed between the opening/closing tape 40 and the back side film 20.

On the other hand, the second closing part 52 is for opening and closing between the back side tape-shaped area 42 and the back side film 20, and allows the female type articulating tool 52 ₁ and the male type articulating tool 52 ₂ to fit together. It is made up of. Of course, both of the articulating tools 52 ₁ and 52 ₂ extend over the entire length of the pouch 100 in the width direction.

The female articulating tool 52 ₁ is integrated with and fixed to the back side tape-like area 42 of the opening/closing tape 40 , and the male articulating tool 52 ₂ is fixed to the back side film 20 . By fitting the female articulating tool 52 ₁ and the male articulating tool 52 ₂ together, the space between the back side tape-shaped area 42 and the back side film 20 can be closed. On the other hand, if the engagement tools 52 ₁ and 52 ₂ are disengaged, a passage for the contents to pass through can be formed between the back side tape-shaped area 42 of the opening/closing tape 40 and the back side film 20.

As can be seen from FIG. 1(b), the contents of this pouch 100 are sealed inside, and the contents will not leak out before the pouch 100 is opened. When taking out the contents, it is possible to take out the contents in two ways. That is, first, the contents can be taken out little by little via the dispensing hole 34. Further, it is also possible to take out a large amount of contents without passing through the dispensing hole 34.

Therefore, with reference to FIG. 2(a), first, a method for taking out small amounts will be explained. In order to take out the contents from this pouch 100, it is first necessary to cut the pouch 100 along the planned cutting line e and open the first closed portion 51.

Then, by breaking the opening/closing tape 40 at the easy-to-break line 43, the contents can be taken out through the drawing hole 34 and the broken easy-to-break line 43, as shown by the arrow in FIG. 2(a). can.

On the other hand, by opening the second closing part 52, as shown by the arrow in FIG. By tilting the container itself, it is possible to take out a large amount of the contents.

In addition, when taking out a large amount in this way, it is not necessary to break the opening/closing tape 40 at the easy break line 43, but even if it is broken at the easy break line 43 as shown in FIG. 2(b), , it is also possible to take out large quantities. If the opening/closing tape 40 is broken at the easy-to-break line 43, open the pouch 100 by pinching the front tape-like area 41 where the first closing part 51 is located, and shake it little by little as shown in FIG. 2(a). I can put it out. On the other hand, if the pouch 100 is opened by pinching the back side tape-shaped area 42 where the second closure part 52 is located, a large amount can be taken out as shown in FIG. 2(b). Since the height of the front tape-shaped area 41 and the height of the back tape-shaped area 42 are different, there is no possibility of confusing them.

Since both the first closing part 51 and the second closing part 52 are configured to be openable and closable, even after they are opened, they can be closed to remove the contents remaining in the pouch 100. It is possible to seal it again.

For example, the pouch 100 can be resealed by dispensing a small amount of contents through the dispensing hole 34 and the broken easy-to-break line 43 and then closing the first closing portion 51.

Moreover, after opening the second closing part 52 and taking out the contents, the pouch 100 can be resealed by closing either the first closing part 51 or the second closing part 52. Further, even if the opening/closing tape 40 is broken at the easy-to-break line 44 while opening the second closing part 43, the remaining contents are sealed in the pouch 100 by closing the first closing part 51. Is possible.

In addition, even in the pouch 100 resealed in this way, as shown in FIG. It is clear that by setting the container in this state, the contents can be taken out little by little through the dispensing hole 34 and the broken easy-to-break line 43. Of course, by opening both the first closure part 51 and the second closure part 52, it is possible to take out a large amount of the remaining contents.

Next, as the front side film 10, the back side film 20, and the intermediate film 30, any film can be used, but a film with a multilayer structure in which a sealant layer is laminated on a base film is suitable.

As the base film, a film having mechanical strength and dimensional stability can be preferably used. For example, various biaxially stretched films. Examples of the material include polyester, polypropylene, polystyrene, nylon, polycarbonate, polyacrylonitrile, and polyimide. The base film may also be a multilayered film in which films made of these various materials are laminated and other films are laminated thereon, or a film provided with a vapor deposited layer or a printed layer may be used as the base film.

Examples of other films include metal foils such as aluminum foils. A base film containing metal foil in its layer structure has excellent barrier properties against water vapor, oxygen gas, and the like.

Next, as the vapor deposition layer, in addition to a metal vapor deposition layer formed by vapor depositing a metal such as aluminum, an inorganic vapor deposition layer made of an inorganic substance can be used. As the inorganic substance, metal oxides such as silicon oxide, aluminum oxide, magnesium oxide, calcium oxide, potassium oxide, tin oxide, sodium oxide, boron oxide, titanium oxide, lead oxide, zirconium oxide, and yttrium oxide can be used. Among them, silicon oxide, aluminum oxide, magnesium oxide, etc. are preferable from the viewpoint of productivity and price. A base film containing such a metal vapor deposited layer or an inorganic vapor deposited layer in its layer structure also has excellent barrier properties against water vapor, oxygen gas, and the like.

A polyolefin resin can be used as the sealant layer. For example, low density polyethylene, linear low density polyethylene, medium density polyethylene, high density polyethylene, ethylene-vinyl acetate copolymer (EVA), ethylene-methacrylic acid copolymer (EMAA), ethylene-ethyl acrylate copolymer These are polyolefin resins such as EAA, ionomer, and polypropylene. These resins may be formed into a film using an extruder and used in the form of a film.

The base film and the sealant layer can be laminated using an adhesive. As the adhesive, a dry laminating adhesive can be used. Examples include two-component curing urethane adhesive, polyester urethane adhesive, polyether urethane adhesive, acrylic adhesive, polyester adhesive, polyamide adhesive, epoxy adhesive, and the like. A dry lamination method can be used as a lamination method. In addition, it is also possible to form a film by melt-extruding an adhesive resin, and press and laminate the base film and the sealant layer while maintaining the adhesive strength.

Further, as the content made of powder or granules, seasonings or the like that can be shaken out little by little are suitable. For example, pepper, shichimi chili pepper, etc. In addition, powdered coffee, cocoa, wheat flour, powdered detergent, etc. may be used. Furthermore, the contents can be granular foods such as chewing gum or chocolate that have been processed into drop shapes.
