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.

Conventionally, in a bottle type container made of synthetic resin or the like, there is a problem in that an empty container after using up the stored material easily causes an increase in dust and environmental destruction. Under these circumstances, products such as kitchen liquid detergents, laundry detergents, softeners, bleaches, and bath shampoos, rinses, body soaps, etc., which have been used in large households in recent years, are used for refilling. It is a container selected from materials that take into consideration the influence on the environment, and is provided by using a packaging container having a shape that is difficult to be bulky, so that the contents can be transferred to the bottle container when necessary.
As a packaging container for refilling, a packaging container is formed as a sealing part made of a synthetic resin made of a single or multi-layer packaging material, with the front sheet and the back sheet stacked and bonded together by heat sealing. When necessary, the opened part is applied to the mouth of a bottle container or the like, and the contents are transferred to the bottle container or the like.
In addition, this refill packaging container in which a liquid content such as liquid is hermetically packaged is self-supporting, and is often a standing pouch that becomes a three-dimensional container. It has a spout part so that it can be completely transferred to another container without spilling outside, and the form of the spout part is narrowed to a part of the top of the container and the front sheet and the rear sheet When the heat seal around the upper part of the container and the surrounding area of the upper part of the container, a separate spout tool made of a plastic molding or the like is sandwiched and thermally bonded. Some of them were attached so as to be integrated with the seal portion, and this was used as a spout portion.

As mentioned above, the spout part in the standing pouch-type packaging containers that have been distributed in the past is a seal part that is formed by stacking two front and back packaging materials. Even if it is cut and opened, the width of the spout part including the pair of seal parts is relatively wide because the seal part continues in a state of being opposed to the top and bottom of the opening of the spout part. In order to improve, the cut out spout part, although embossing is applied to each of the front sheet and the back sheet in the spout part, and a tube material is arranged in advance between the front sheet and the back sheet. However, the spout portion itself is difficult to insert into the mouth portion of the bottle to be refilled, for example, the inner diameter of the mouth portion is 20 mm or less, even if it is inserted, To have pledged in the mouth portion Lumpur unit also becomes accompanied, Note flow convergent accommodating product opening shape been distorted in the outlet portion, it has led to the result that it is difficult to have refilled as a result.
Moreover, in the form of attaching the separate spout tool as described above integrally with the seal portion, the manufacturing cost of the packaging container itself is greatly increased, and it is necessary to attach a cap to the separate spout tool. For example, it was unsuitable for use as a packaging container for refilling.

  On the other hand, as shown in Patent Document 1, it is a flat pouch-shaped packaging container in which the upper sheet and the lower sheet are overlapped and the periphery is a seal part, and is folded at the center of the container when necessary, and one end of the folding position. A device has been proposed in which the contents can be poured out from the spout portion formed on the side. This packaging container is easy to insert into the mouth of an empty container or the like because the user himself who wants to refill the contents in an empty container or the like bends the packaging container to make the pouring part thinner.

JP 2004-323077 A

However, in the above-mentioned flat pouch-shaped packaging container, first, the product filled with the contents using this packaging container cannot be placed on the product display shelf in the store in a standing state, and must be stacked flatly. In addition, the eye catching effect as a product becomes extremely poor, and a large problem arises in stability when a plurality of products are stacked. Also, it takes time and effort to bend the product on the end user side, and when it is further folded, the two packaging materials (upper sheet and lower sheet) are almost joined together at the pouring part. Even if the part is cut, the opening does not open, and there is a possibility that a big problem in handling will occur that the end user forcibly crushes the packaging container and forcibly opens the dispensing part by the pressure from the contents side Was expensive.
Therefore, in view of the above circumstances, the present invention provides a packaging container having a spout part that can be easily inserted into a mouth part of a bottle container, etc., so that the sealing part of the packaging material is not disposed facing the spout part of the packaging container. It is an object of the present invention to make it easy to perform a refilling operation of the contents.

(Invention of Claim 1)
The present invention has been made in consideration of the above-mentioned problems, and two flexible packaging materials are overlapped so that the respective folding positions are bent upward so as to protrude upward, and the outer packaging is in the folded state. The lower folded portion of the other packaging material that is the inner side in the folded state with respect to the upper folded portion of the material is arranged separately on the container lower side, and the outer packaging material and the inner packaging material are A seal portion is formed on the side and the lower side of the opposed portion, and a seal portion is formed on the side of the outer packaging material facing above the position of the lower bent portion, The packaging portion in which the packaging material and the inner packaging material are opposed to each other is a two-fold packaging container that is divided into two via a folding portion in which the upper folding position and the lower folding portion are opposed to each other. There,
The bent part is located in the container width direction at the upper part of the container, and is surrounded by an end peripheral part of the upper bent part and an end peripheral part of the lower bent part at one end side of the bent part. A spout portion that protrudes in the direction is provided, and the seal portion around the vertical cross section of the spout portion is disposed at the lower portion of the spout portion, and the seal portion disposed at the lower portion of the spout portion The outer peripheral portion of the outer packaging material extending from the upper edge to the upper bent portion is a seal portion nonexistent region ,

(Effect of the invention of claim 1)
According to the first aspect of the present invention, the spout portion disposed on one end side of the folded portion of the two-fold packaging container has the seal portion located at the lower portion thereof, and the upper edge of the seal portion extends from the upper edge. Because the outer packaging material is a folded seal part non-existing region, the seal part does not face up and down in the longitudinal section direction of the spout part, and is placed only on the lower side of the spout part In addition, since the seal portion is not present on the upper side of the spout portion, it is possible to ensure a large vertical dimension of the spout portion itself. Therefore, it becomes possible to easily insert the portion of the spout portion into the mouth portion of the bottle having a small diameter while ensuring a large vertical dimension of the spout portion itself.
Further, in the spout portion that is an extension of the bent portion, in the outer packaging material and the inner packaging material surrounding the spout portion, the upper folded portion and the inner packaging material of the outer packaging material The area where the outer wrapping material and the inner wrapping material face each other is small because the lower bent portion is separated. Therefore, even if a slight pressure is applied from the container flowing into the cut spout, a slight opening between the facing outer packaging materials (opening around the end of the upper folded part) and the inside With the slight opening in the direction in which the packaging material is unfolded from the folded state (opening at the periphery of the end portion of the lower folded portion), the spout portion is formed in a substantially Δ shape and opens in a shape having a wide opening area. Therefore, the contents are smoothly poured out from the widely opened spout portion.
Furthermore, unlike the above-mentioned conventional standing pouch type packaging containers and flat pouch type packaging containers, the bent portion is the upper portion of the container, and the two storage portions are connected to each other by opening downward in a substantially inverted V shape. Since it is a packaging container, self-supporting property is improved. And since the self-supporting property is good, the packaging material can be made thin, so that the container can be reduced in weight. And it has the effect that it is easy to give moderate flexibility and strength required for handling the container together, and the center of gravity when it is installed is lowered, and a sense of stability is easily created in the form at the time of product display.

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 superposing a packaging material 2 and a packaging material 3 made of a flexible synthetic resin packaging material, both of which have the same laminated structure, and bending each of them. It is in a state of being bent so that the position is convex upward, and heat sealing is performed in the periphery of the packaging material 2 that is the outer side and the packaging material 3 that is the inner side according to this bent state. Seal portions 4 are formed on the side and bottom sides.

  Moreover, in this packaging container 1, as shown in the figure, the upper folded portion 2a of the outer packaging material 2 and the lower folded portion 3a of the inner packaging material 3 do not overlap with each other, and are not folded. The lower bent portion 3a is disposed away from the lower portion of the container with respect to the portion 2a. And since the upper bending part 2a and the lower bending part 3a are separated up and down in this way, the outer packaging material 2 is in a state of being opposed above the position of the lower bending part 3a. A seal portion 4 is formed by heat-sealing the outer packaging material 2 to each other on both sides of the outer packaging material 2, and sealing is performed on the sides of the packaging material 2 and the packaging material 3 described above. The part 4 and the seal part 4 on the side on the upper side from the lower bent part 3a are continuous.

  The storage part 5 formed by overlapping the two packaging materials 2 and 3 to be opposed to each other is divided into two via a bent part 6 in which the upper bent part 2a and the lower bent position 3a are opposed to each other. The bent portions 6 are in communication with each other with the bent portion 6 therebetween.

  As shown in the drawing, one side in the longitudinal direction of the bent portion 6 on the container upper side, that is, one side in the container width direction is convex toward the container side so as to be continuous with the portion of the bent portion 6. A spout portion 7 is located. The shape which becomes the convex toward the container side of the spout part 7 is a seal part on the side of the side where the spout part 7 of each of the storage parts 5 divided into two is convex. 4 is formed so as to enter the center side of the storage part 5, and as shown in the figure, the seal part 4 on the same side in each of the storage parts 5 is lower than the lower bent part 3a. The curved seal portion 8 having a curved shape so as to protrude from the height position toward the center of the storage portion 5 is provided. In this way, the bent seal portion 8 is formed below the spout portion 7 and protrudes inwardly from the lower position of the lower bent portion 3a toward the inside of the storage portion 5, so that the spout portion 7 The lower seal portion 4 is formed by an upper seal portion of the curved seal portion 8.

  In the present embodiment, at the lower part of the spout portion 7, the curved seal portion 8 is shaped so as to be convex toward the center of the storage portion 5, and the seal portion 4 on the upper side of the curved seal portion 8 is disposed at the spout. Since it is positioned below the portion 7, the upper seal portion in the curved seal portion 8 is arranged around the vertical end surface of the spout portion 7 (around the cross section in the direction perpendicular to the longitudinal direction of the curved bent portion 6). 4 is arranged, and the portion corresponding to the spout portion of the two packaging materials formed surrounding the spout portion 7, that is, the peripheral portion 9 and the lower fold portion at one end of the upper folded portion 2a The two seal portions 4 that connect the peripheral portion 10 at one end of 3a are both lower than the spout portion 7, and the top of the seal portion 4 is arranged around the longitudinal section of the spout portion 7 as shown in FIG. Upper bent portion of the region extending from the edge position to the upper bent portion 2a Periphery 9 of the end portion of a is formed as a sealing portion absent area 11 where the sealing portion is not present. As described above, since the peripheral portion 9 extending from the upper edge of the seal portion 4 below the spout portion 7 to the upper bent portion 2a is used as the seal portion non-existing region 11, the conventional seal portion does not face each other vertically. In addition, since the seal portion is not provided on the upper side of the spout port portion because it is disposed only on the lower side of the spout port portion 7, the vertical dimension of the spout port itself can be ensured. Therefore, it is possible to easily insert the portion of the spout portion into the mouth portion of the bottle having a small diameter, while increasing the vertical dimension of the spout portion itself and ensuring the ease of flowing out.

In the packaging container 1 in the illustrated example, a knob portion 12 is provided on the protruding side seal portion 4 of the spout portion 7, and a knob portion 12 is provided by extending the protruding side seal portion 4 of the spout portion 7 below the container. The half-cut 13 is irradiated with laser as a planned opening position on the surface of the peripheral edge portion 9 extending from the boundary position between the knob portion 12 and the lower seal portion 4 of the spout portion 7 to the upper bent portion 2a. The spout portion 7 can be cut by hand operation while holding the knob portion 12.
Further, the knob portion 12 may be configured to be continuous with the curved seal portion 8 as shown in FIG. That is, in the example shown in FIG. 4, a knob portion 12 that seals the outer packaging material 2 and the inner packaging material 3 is arranged on the outer edge side of the curved seal portion 8, and the knob portion 12 is scheduled to be opened. It is assumed that it is connected from the position through a perforated portion 14 that is easy to break along the curved seal portion 8, and the knob portion 12 is also continuous with the seal portion 4 located on the protruding tip side of the spout portion 7. By forming the side seal portion wide by heat sealing at the position where the curved seal portion 8 is located, a wide knob portion 12 can be easily formed. The tearing force at the time of cutting is surely applied to the planned opening position from the wide knob portion 12, and the cutting operation is simple.

In the example of the drawing, in order to further stabilize the lower opening form of the folded package container 1, a banding 15 that is turned to two storage portions is provided. Of course, the method for stabilizing the downward opening form is not limited to banding, and partial shrink wrapping may be performed.
Moreover, although the example formed from two packaging materials was demonstrated in the Example, this invention is not limited to this, The packaging material of the same structure is used as an outer packaging material as a bottom sheet on the container bottom side. It is good also as a structure which can be opened by the expansion | deployment of the packaging material used as a bottom sheet | seat by making it fold between the bottom side part of the inner packaging material, and the storage part.

The packaging material used for the two-fold packaging container of this 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 / adhesion For example, a layered structure of agent layer / intermediate layer / adhesive layer / sealant layer / (inner layer side).
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.
