Description

The present invention relates to a storage container.

In recent years, refill storage containers for storing liquid seasonings, cosmetics, liquid detergents, and the like have been widely used. Most of such storage containers are formed by sticking two films on the front and back. Further, the storage container for refilling is provided with a spout having an arbitrary width suitable for the diameter of the container to be refilled in order to facilitate the refilling work.

The opening area of this spout has a great influence on the flow rate when pouring the contents. Conventionally, a storage container has been proposed in which the opening area of the spout is secured by inflating the film itself near the spout to form a three-dimensional shape. For example, Patent Document 1 includes two body forming sheets and a bottom forming sheet arranged at the lower end between the body forming sheets, and is formed by heat-bonding the peripheral edges of these sheets. The self-supporting bag has been disclosed. A spout portion for pouring out the contents is provided on the upper part of the self-standing bag, and an assembly ruled line is provided on the two body forming sheets of the spout portion. Since the spouting port portion is easily three-dimensionalized when the contents are poured out by this assembly ruled line, the contents can be poured smoothly without blocking the spouting port portion.

Further, a storage container has been proposed in which an opening area of the spout is secured by inserting a member different from the film into the spout. For example, Patent Document 2 provides a film material comprising two side walls connected to each other by a longitudinal weld at an edge, one bottom, and a pouring means provided in a corner or edge region. Made of bags are disclosed. The pouring means has a flow path and a small tube provided in the flow path. With this configuration, it is possible to prevent the flow path for discharging the contents from being crushed in the bag and to secure the flow path for smoothly discharging the contents.

In a storage container provided with a spout that inflates the film itself near the spout to form a three-dimensional shape, such as the self-standing bag disclosed in Patent Document 1, the contents are poured by opening from a part of the spout. When ejecting, the pressure of the contents may cause the area near the base of the spout to swell. As a result, the opening of the spout may be pulled toward the bonded ends of the spout, and the front and back films may approach each other to narrow the opening. In this case, there arises a problem that the opening is closed and the contents are not poured out.

Further, when a molded member such as a small tube or a spout is used as a separate member as in the bag disclosed in Patent Document 2, a member cost is incurred. Further, if this member is present, the container is not flattened before filling, so that the transportation efficiency is lowered and the filling suitability is also adversely affected. Therefore, the cost of the product becomes high. Further, since the flow rate at the time of pouring depends on the inner diameter of the mouth of a member such as a small pipe, the consumer cannot control the flow rate by squeezing the storage container or the like. Therefore, it is necessary to select the optimum member based on the viscosity of the liquid content and the inner diameter of the mouth of the container to be refilled.

An object of the present invention is to provide a storage container capable of stably and quickly pouring out the contents without blocking the spout at the time of refilling while suppressing the cost of the product.

The storage container according to one aspect of the present invention includes a front surface member, a back surface member, a peripheral edge portion formed by joining the peripheral edge of the front surface member and the peripheral edge of the back surface member to each other, and the front surface member and the back surface. A storage container including a liquid storage portion formed between the front member and the back member by joining with the member, which is provided in a part of the peripheral portion and is removed to provide a spout. It is provided with a spout forming portion to be formed, and a pouring flow path provided between the spout and the liquid accommodating portion and communicating from the spout to the liquid accommodating portion. The pouring flow path includes a first embossed portion that extends linearly from the pouring outlet toward the liquid accommodating portion, is formed in a convex shape that bulges outward, and has a constant width direction, and the above-mentioned. The second embossed portion, which is provided above the first embossed portion and is formed in a concave shape which is recessed inward, is separated from the first embossed portion, and is separated from the first embossed portion. It has a third embossed portion that is provided below the first embossed portion and is formed in a concave shape that is recessed inward. The second embossed portion includes a first line portion formed in a straight line extending away from the first embossed portion as it goes from the spout to the liquid storage portion, and the first wire portion. It has a second line portion formed in a straight line which is connected to the end portion on the liquid storage portion side and extends from the end portion of the first wire portion so as to approach the first embossed portion. .. The third embossed portion includes a linearly formed third wire portion extending away from the first embossed portion as it goes from the spout to the liquid storage portion, and the third wire portion. It has a fourth wire portion formed in a straight line extending from the end portion of the third wire portion to the end portion on the liquid storage portion side so as to approach the first embossed portion. ..

In the above storage container, the angle formed by the first wire portion and the second wire portion may be 90 degrees or more and less than 180 degrees.

In the above storage container, the width direction dimension of the first embossed portion and the width direction dimension of the second embossed portion may be 0.5 mm or more and 5.0 mm or less.

In the above storage container, the spout forming portion may have a cut portion that has been scratched.

According to the above storage container, when the contents are poured out, a convex first embossed portion, a concave second embossed portion having a first wire portion and a second wire portion, and a third A truss structure is formed in the pouring flow path by the concave third embossed portion having the wire portion and the fourth wire portion. In this truss structure, it is possible to prevent the liquid storage portion side of the pouring flow path from swelling due to the second wire portion and the fourth wire portion 23B. Therefore, the contents can be poured out in a state where the pouring flow rate of the contents is stable without blocking the opening of the pouring outlet. Therefore, the contents can be quickly dispensed without interrupting the dispensing work on the way. Further, the above-mentioned storage container does not include a separate member such as a small tube disclosed in Patent Document 2. Therefore, an increase in product cost can be suppressed.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a front view showing a storage container 1 according to the present embodiment. FIG. 2 is a cross-sectional view taken along the line AA of FIG. FIG. 3 is an enlarged perspective view showing the upper part of the storage container 1. The storage container 1 is a container for refilling, and is used as, for example, a pouch (bag-shaped flexible package). The inside of the storage container 1 is filled with a liquid content for replenishing the main body container, which is the container to be refilled. Examples of the contents include liquid seasonings, cosmetics, liquid detergents and the like.

As shown in FIGS. 1 and 2, the storage container 1 includes a front member 2 and a back member 3 joined to the front member 2. Further, a bottom surface member 4 is provided between the lower portion of the front surface member 2 and the lower portion of the back surface member 3. The front member 2, the back member 3, and the bottom member 4 are made of a flexible plastic film (or sheet). This film is formed by laminating a base material layer and a sealant. A film having a known structure used as a pouch can be applied to the front member 2, the back member 3, and the bottom member 4. As an example, the film has a two-layer structure consisting of a nylon (NY) film as the outer substrate layer and a linear low density polyethylene (LLDPE) film as the inner sealant.

The peripheral edge of the front surface member 2 and the peripheral edge of the back surface member 3 are joined to each other by heat-sealing a heat-sealing sealant to form a peripheral edge portion 5. Similarly, in the lower part of the storage container 1, the front end 4A of the bottom member 4 and the lower end 2A of the front member 2 are joined to each other by heat fusion in a state where the bottom member 4 is folded so as to be convex upward. Then, the rear end 4B of the bottom member 4 and the lower end 3A of the back member 3 are joined to each other by heat fusion. Further, the front end 4A and the rear end 4B of the bottom member 4 are joined to each other by heat fusion at both left and right ends. By joining the front member 2 and the back member 3 in this way, a liquid storage portion 6 for storing the contents is formed between the front member 2 and the back member 3. When the contents are filled in the liquid storage portion 6, the crease 4C of the bottom member 4 moves downward due to the weight of the contents, and the bottom member 4 expands in the front-rear direction. As a result, the volume of the storage container 1 is increased, and the storage container 1 is imparted with independence.

A spout forming portion 7 is provided in a part of the peripheral edge portion 5. By removing the spout forming portion 7, a spout 8 for pouring out the contents is formed. The position of the spout forming portion 7 is not particularly limited as long as the pouring of the contents is not hindered. For example, in FIG. 1, the spout forming portion 7 is provided in the upper left portion of the peripheral edge portion 5. The spout forming portion 7 has a cut portion 9 formed along the spout 8. By cutting the spout forming portion 7 along the cut portion 9, the cut portion 9 can be removed from the storage container 1 and the spout 8 is formed. In addition, in order to improve the linear cut property of the cut portion 9, the cut portion 9 may be scratched.

A pouring flow path 10 is provided between the pouring outlet 8 and the liquid storage unit 6. The pouring flow path 10 is composed of a front member 2 and a back member 3 joined to each other, and communicates from the pouring outlet 8 to the liquid storage portion 6. That is, the contents stored in the liquid storage unit 6 pass through the pouring flow path 10 and are poured out from the pouring outlet 8. As shown in FIGS. 1 and 3, the pouring flow path 10 has a first embossed portion 11 formed in a convex shape bulging outward and a second embossing portion 11 formed in a concave shape recessed inward. It has a part 12. The first embossed portion 11 extends linearly from the spout 8 toward the liquid storage portion 6. The second embossed portion 12 is provided above the first embossed portion 11 at a distance from the first embossed portion 11. Further, the second embossed portion 12 includes a first line portion 12A formed in a straight line extending from the spout 8 toward the liquid storage portion 6 so as to be separated from the first embossed portion 11, and a first line portion 12A. A second wire portion that is connected to the end portion 12C of the wire portion 12A on the liquid storage portion 6 side and extends from the end portion 12C of the first wire portion 12A so as to approach the first embossed portion 11. It has 12B and. Here, the outside is the direction from the liquid storage portion 6 inside the storage container 1 toward the surface of the front member 2 or the back member 3 (the surface forming the outer surface of the storage container 1), and the inside is , In the opposite direction to the outside.

The first embossed portion 11 and the second embossed portion 12 are formed by embossing the front member 2 and the back member 3. The first embossed portion 11 and the second embossed portion 12 are formed on both the front member 2 and the back member 3. The first embossed portion 11 formed on the front member 2 and the first embossed portion 11 formed on the back member 3 are provided at positions facing each other (positions overlapping each other in the front view of the storage container 1). Similarly, the second embossed portion 12 formed on the front member 2 and the second embossed portion 12 formed on the back member 3 are provided at positions facing each other.

In the second embossed portion 12, the first wire portion 12A and the second wire portion 12B are provided at an angle α. Here, the angle α is the angle formed by the first wire portion 12A and the second wire portion 12B on the side facing the first embossed portion 11. For example, in the second embossed portion 12 shown in FIG. 1, the angle α formed by the first line portion 12A and the second line portion 12B is 130 degrees. Considering the effect of suppressing the swelling of the pouring flow path 10 by the second embossing portion 12, which will be described later, the angle α is set so that the second wire portion 12B extends toward the liquid storage portion 6 side of the pouring flow path 10. It is preferably 90 degrees or more and less than 180 degrees.

The arrangement of the first embossed portion 11 and the second embossed portion 12 in the pouring flow path 10 may be appropriately set according to the overall dimensions of the storage container 1, the physical properties of the contents, and the like. For example, by setting the position of the first embossed portion 11 at the spout 8 to a position above the center of the spout 8, the contents are first ejected when the storage container 1 is tilted to pour out the contents. It can be dispensed from a position above the center of the spout 8 along the embossed portion 11.

The dimensions of the first embossed portion 11 in the longitudinal direction may be appropriately set according to the overall dimensions of the storage container 1, the physical properties of the contents, and the like. Similarly, the longitudinal dimensions of the second embossed portion 12 (the longitudinal dimensions of the first wire portion 12A and the longitudinal dimensions of the second wire portion 12B) are the overall dimensions and contents of the storage container 1. It may be set as appropriate according to the physical properties of the object. Further, the width direction dimension of the first embossed portion 11 and the width direction dimension of the second embossed portion may be appropriately set according to the overall dimensions of the storage container 1, the physical properties of the contents, and the like, but are preferable. Is 0.5 mm or more and 5.0 mm or less. The widthwise dimension of the first embossed portion 11 and the widthwise dimension of the second embossed portion may be constant or variable along the longitudinal or stretching direction. Here, the width direction is a direction perpendicular to the longitudinal direction and substantially parallel to the surface of the front member 2 or the surface of the back member 3.

Next, the operation of the storage container 1 configured as described above during use will be described. FIG. 4 is a diagram showing a state in which the storage container 1 is used.

First, the user cuts and removes the spout forming portion 7 of the storage container 1 filled with the contents along the cut portion 9, and opens the spout 8. As shown in FIG. 4, the spout 8 is inserted into the opening 101 of the main body container 100 while tilting the storage container 1, and the contents of the storage container 1 are refilled into the main body container 100.

At this time, the weight (pressure) of the contents is applied to the pouring flow path 10. Since the pouring flow path 10 is provided with the first embossed portion 11 formed in a convex shape, the portion of the pouring flow path 10 provided with the first embossed portion 11 bulges outward. At the same time, since the pouring flow path 10 is provided with the second embossed portion formed in a concave shape on the upper side of the first embossed portion 11, the second embossed portion 12 of the pouring flow path 10 is provided. The embossed part tends to protrude inward. Therefore, it is possible to prevent the portion of the pouring flow path 10 provided with the second embossed portion 12 from swelling, and prevent the entire base of the pouring flow path 10 (the portion on the liquid storage portion 6 side) from swelling. NS. This makes it difficult for the opening of the spout 8 to close. At the same time, the opening of the spout 8 can be suitably widened in a direction in which the first embossed portion 11 formed on the front member 2 and the first embossed portion 11 formed on the back member 3 are separated from each other. can.

Further, the concavely formed second embossed portion 12 is a linearly formed second wire portion 12B extending from the end portion 12C of the first wire portion 12A so as to approach the first embossed portion 11. Has. Since the portion of the pouring flow path 10 provided with the second wire portion 12B tends to protrude inward, it is possible to suppress the swelling of the pouring flow path 10 on the liquid storage portion 6 side due to the pressure of the contents. A truss structure is formed in the pouring flow path 10 by the first wire portion 12A and the second wire portion 12B of the convex first embossed portion 11 and the concave second embossed portion 12. With this truss structure, it is possible to maintain a state in which the pouring outlet 8 is preferably opened and the swelling of the pouring flow path 10 on the liquid storage portion 6 side is suppressed while the contents are poured out. Therefore, the user can quickly dispense the contents without interrupting the dispensing work in the middle.

In the conventional storage container, the pressure of the contents causes the liquid storage portion side of the pouring flow path to swell excessively, which may pull the spout outlet toward both ends and block the spout outlet opening. .. On the other hand, in the storage container 1 according to the present embodiment, since the pouring flow path 10 has the second embossed portion 12, the opening of the pouring outlet 8 is not blocked as described above, and the contents are not blocked. The contents can be dispensed in a state where the pouring flow rate is stable. It is also possible to increase (adjust) the pouring flow rate by pushing the liquid storage unit 6 of the storage container 1.

Further, the storage container 1 according to the present embodiment does not have a molding member in the pouring flow path, as opposed to the conventional storage container having a molding member such as a small tube in the pouring flow path. Therefore, the product cost can be reduced as compared with the conventional storage container.
