Description

  The present invention relates to a storage container.

  In recent years, refillable storage containers for storing liquid seasonings, cosmetics, liquid detergents and the like have been widely used. Many of such storage containers are formed by bonding two front and back films. In addition, the refill storage container is provided with a spout having an arbitrary width suitable for the diameter of the refill destination container in order to facilitate the refill operation.

  The opening area of the spout greatly affects the flow rate when the contents are poured. 2. Description of the Related Art Conventionally, there has been proposed a storage container that secures an opening area of a spout by expanding the film itself near the spout into a three-dimensional shape. For example, Patent Document 1 includes two body forming sheets and a bottom forming sheet disposed at the lower end between the body forming sheets, and the edges of these sheets are formed by thermal bonding. A self-supporting bag is disclosed. A spout part for pouring out the contents is provided at the upper part of the self-supporting bag, and two body part forming sheets of the spout part are provided with assembling ruled lines. This assembly ruled line makes it easier for the spout portion to become three-dimensional when the contents are poured out, so that the contents can be poured smoothly without clogging the spout portion.

  In addition, there has been proposed a storage container that secures an opening area of the spout by inserting a member different from the film into the spout. For example, Patent Document 2 discloses a film material comprising two side walls joined to each other by a longitudinal weld at an edge, one bottom, and a pouring means provided in a corner portion or an edge portion region. A manufactured bag is 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 in the bag from being crushed and to secure a flow path for smoothly discharging the contents.

JP 2009-57071 A JP-A-5-132069

  As in the self-supporting bag disclosed in Patent Document 1, in a storage container provided with a spout in which the film near the spout is inflated into a three-dimensional shape, the contents are poured by opening from a part of the spout. When taking out, the vicinity of the base of the spout may swell due to the pressure of the contents. Thereby, the opening part of a spout may be pulled toward the both ends to which the spout is adhered, and the opening may be narrowed by approaching the front and back films. 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 mouthpiece (spout) is used as a separate member like the bag disclosed in Patent Document 2, member costs are 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. For this reason, the cost of a product will become high. Furthermore, since the flow rate at the time of dispensing 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. Therefore, it is necessary to select an optimum member based on the viscosity of the liquid of the contents and the inner diameter of the refill destination container.

  An object of this invention is to provide the storage container which can pour out the content stably and rapidly, without suppressing a spout, at the time of refilling, suppressing the cost of a product.

  A storage container according to an aspect of the present invention includes a front member, a back member, a peripheral portion formed by joining a peripheral edge of the front member and a peripheral edge of the back member, the front member, and the back surface. A storage container including a liquid storage part formed between the front member and the back member by joining with a member, the spout being provided at a part of the peripheral part and removed. A spout forming portion that is formed; and a spout passage that is provided between the spout and the liquid storage portion and communicates from the spout port to the liquid storage portion. The pouring channel extends linearly from the pouring port toward the liquid storage portion, and is spaced apart from the first embossed portion formed in a convex shape that bulges outward. And a second embossed portion provided in an upper side than the first embossed portion and formed in a concave shape recessed inward. The second embossed portion includes a first line portion formed in a straight line extending away from the first embossed portion toward the liquid storage portion from the spout, and the first line portion. A second line portion formed in a straight line extending from the end portion of the first line portion so as to approach the first embossed portion. .

  In the above storage container, an angle formed by the first line portion and the second line 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 part and the width direction dimension of the second embossed part may be not less than 0.5 mm and not more than 5.0 mm.

  In the above storage container, the pouring channel is provided at a lower side than the first embossed part and spaced from the first embossed part, and is formed in a concave shape recessed inward. You may further have an embossing part. The third embossed portion has a third line portion formed in a straight line extending away from the first embossed portion from the spout toward the liquid storage portion, and the third line portion. And a fourth line portion formed in a straight line extending from the end portion of the third line portion so as to approach the first embossed portion. May be.

  In the above-described storage container, the discharge channel is provided above the second embossed part so as to be separated from the second embossed part, and the second as the liquid outlet is moved from the spout. A fourth embossed portion which is linearly formed so as to be separated from the embossed portion and is recessed inwardly, and is separated from the first embossed portion and below the first embossed portion A fifth embossed portion that is linearly formed so as to be separated from the first embossed portion toward the liquid storage portion from the spout, and is formed in a concave shape recessed inward. You may have.

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

  According to the above storage container, when the contents are poured out, the first embossed portion having the convex shape and the concave second embossed portion having the first line portion and the second line portion are poured. A truss structure is formed in the outlet channel. In this truss structure, it is possible to prevent the liquid storage part side of the extraction flow path from being swollen by the second line part. For this reason, it is possible to pour the contents in a state where the pour flow rate of the contents is stable without closing the opening of the spout. Therefore, the content can be quickly extracted without interrupting the extraction operation on the way. Further, the storage container does not include another member such as a small tube disclosed in Patent Document 2. For this reason, the increase in product cost can be suppressed.

It is a front view which shows the other modification of the said storage container. 6 is a front view showing a storage container of Comparative Example 1. FIG. 10 is a front view showing a storage container of Comparative Example 2. FIG.

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

  FIG. 1 is a front view showing a storage container 1 according to the present embodiment. 2 is a cross-sectional view taken along line AA in 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-like flexible package). The interior of the storage container 1 is filled with a liquid content for replenishing a main body container that is a refill destination container. Examples of the contents include liquid seasonings, cosmetics, and liquid detergents.

  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. A bottom member 4 is provided between the lower part of the front member 2 and the lower part of the rear member 3. The front member 2, the back member 3, and the bottom member 4 are made of a plastic film (or sheet) having flexibility. This film is configured by laminating a base material layer and a sealant. A film having a known configuration 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 member 2 and the peripheral edge of the back member 3 are joined to each other by heat-sealing a sealant having heat-fusibility to form the peripheral edge portion 5. Similarly, the front end 4A of the bottom surface member 4 and the lower end 2A of the front surface member 2 are joined to each other by thermal fusion in a state where the bottom surface member 4 is folded so as to protrude upward at the lower portion of the storage container 1. 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 thermal fusion. Further, the front end 4A and the rear end 4B of the bottom member 4 are joined to each other by thermal fusion at both left and right ends. In this way, the front member 2 and the back member 3 are joined together, whereby a liquid storage portion 6 that stores the contents is formed between the front member 2 and the back member 3. When the contents are filled in the liquid storage unit 6, the fold line 4C of the bottom member 4 moves downward due to the weight of the contents, and the bottom member 4 spreads in the front-rear direction. Thereby, while the volume of the storage container 1 increases, self-supporting property is provided to the storage container 1.

  A spout forming part 7 is provided in a part of the peripheral edge part 5. By removing the spout forming part 7, a spout 8 for pouring the contents is formed. The position of the spout formation part 7 is not particularly limited as long as there is no hindrance to the contents. 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 part 7 has a cutout part 9 formed along the spout 8. By cutting the spout formation part 7 along the cut part 9, the cut part 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 part 9, the cut part 9 may be scratched.

  A pouring channel 10 is provided between the pouring port 8 and the liquid storage unit 6. The pouring channel 10 is constituted by the front member 2 and the back member 3 joined to each other, and communicates from the spout 8 to the liquid storage unit 6. That is, the contents stored in the liquid storage unit 6 pass through the extraction channel 10 and are extracted from the outlet 8. As shown in FIG. 1 and FIG. 3, the dispensing flow path 10 includes a first embossed portion 11 formed in a convex shape bulging outward and a second embossed formed in a concave shape recessed inward. 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 so as to be separated from the first embossed portion 11. The second embossed portion 12 includes a first line portion 12A formed in a linear shape extending so as to be separated from the first embossed portion 11 from the spout 8 toward the liquid storage portion 6, and the first embossed portion 12 A second line portion formed in a straight line that is connected to the end portion 12C of the line portion 12A on the liquid storage portion 6 side and extends from the end portion 12C of the first line portion 12A so as to approach the first embossed portion 11. 12B. Here, the outward direction is a 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). , 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 part 11 formed on the front member 2 and the first embossed part 11 formed on the back member 3 are provided at positions facing each other (positions overlapping each other when the storage container 1 is viewed from the front). Similarly, the 2nd embossed part 12 formed in the front member 2 and the 2nd embossed part 12 formed in the back member 3 are provided in the mutually opposing position.

  In the second embossed portion 12, the first line portion 12A and the second line portion 12B are provided with an angle α. Here, the angle α is an angle on the side facing the first embossed portion 11 among the angles formed by the first line portion 12A and the second line portion 12B. 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 extraction flow path 10 by the second embossed portion 12 described later, the angle α is set so that the second line portion 12B extends toward the liquid storage portion 6 side of the extraction 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 extraction flow path 10 may be appropriately set according to the overall dimensions of the storage container 1 and the physical properties of the contents. 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, when the storage container 1 is tilted and the content is poured out, the first content is removed. It can pour out from the position above the center of spout 8 along embossed part 11 of this.

  The dimension in the longitudinal direction of the first embossed portion 11 may be appropriately set according to the overall dimensions of the storage container 1 and the physical properties of the contents. Similarly, the dimension in the longitudinal direction of the second embossed part 12 (the dimension in the longitudinal direction of the first line part 12A and the dimension in the longitudinal direction of the second line part 12B) is the overall dimension and content of the storage container 1. It may be set as appropriate according to the physical properties of the material. Moreover, although the dimension of the width direction of the 1st embossed part 11 and the dimension of the width direction of the 2nd embossed part may be suitably set according to the whole dimension of the storage container 1, the physical property of the content, etc., it is preferable. Is 0.5 mm or more and 5.0 mm or less. The dimension in the width direction of the first embossed part 11 and the dimension in the width direction of the second embossed part 11 may be constant or may vary along the longitudinal direction or the extending 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 | movement at the time of use of the storage container 1 comprised as mentioned above is demonstrated. FIG. 4 is a diagram illustrating a state when the storage container 1 is in use.

  First, the user cuts and removes the spout forming portion 7 of the storage container 1 filled with the contents along the cutout portion 9 to open the spout 8. As shown in FIG. 4, while the storage container 1 is tilted, the spout 8 is inserted into the opening 101 of the main body container 100, 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 extraction channel 10. Since the extraction channel 10 is provided with the first embossed portion 11 formed in a convex shape, the portion of the extraction channel 10 where the first embossed portion 11 is provided expands outward. At the same time, since the second embossed portion formed in a concave shape is provided on the upper side of the first embossed portion 11 in the outlet channel 10, the second embossed portion 12 is provided in the outlet channel 10. The portion thus formed tends to protrude inward. For this reason, it is suppressed that the part in which the 2nd embossed part 12 of the extraction flow path 10 was provided swells, and it is prevented that the whole root (part by the side of the liquid storage part 6) of the extraction flow path 10 expands. The Thereby, it becomes difficult to close the opening of the spout 8. At the same time, the opening of the spout 8 can be suitably widened in a direction in which the first embossed part 11 formed on the front member 2 and the first embossed part 11 formed on the back member 3 are separated from each other. it can.

  The second embossed portion 12 formed in a concave shape is a second line portion 12B formed in a linear shape extending so as to approach the first embossed portion 11 from the end portion 12C of the first line portion 12A. Have Since the portion where the second line portion 12B of the extraction channel 10 is provided is easily protruded inward, the bulge on the liquid storage unit 6 side of the extraction channel 10 due to the pressure of the contents can be suppressed. A truss structure is formed in the extraction flow path 10 by the convex first embossed portion 11 and the first line portion 12A and the second line portion 12B of the concave second embossed portion 12. With this truss structure, it is possible to maintain a state in which the spout 8 is suitably opened and the swelling of the spout passage 10 on the liquid storage section 6 side is suppressed while the contents are poured out. Therefore, the user can quickly extract the contents without interrupting the extraction operation on the way.

  In the conventional storage container, the liquid storage part side of the extraction flow path is excessively expanded by the pressure of the contents, so that the outlet is pulled toward both ends, and the opening of the outlet may be blocked. . On the other hand, in the storage container 1 according to the present embodiment, since the extraction channel 10 has the second embossed portion 12, the opening portion of the outlet 8 is not blocked as described above, and the content of The contents can be poured out in a stable state. It is also possible to increase (adjust) the dispensing flow rate by pushing the liquid storage part 6 of the storage container 1.

  Moreover, the storage container 1 which concerns on this embodiment does not have a shaping | molding member in the extraction flow path with respect to the conventional storage container which has shaping | molding members, such as a small tube, in the extraction flow path. For this reason, product cost can be reduced compared with the conventional storage container.

(Example)
Next, the storage container according to the present embodiment will be further described using examples and comparative examples. However, the present invention is not limited to the following examples.

  As Example 1 of the present invention, the storage container 31 of Modification 2 shown in FIG. 6 was used. A film having a two-layer structure of NY15 / LLDPE 120 was used for the front member 2, the back member 3, and the bottom member 4.

  As Comparative Example 1, the storage container 40 shown in FIG. 7 was used. FIG. 7 is a front view showing the storage container 40 of the first comparative example. As shown in FIG. 7, the storage container 40 of Comparative Example 1 does not have the first embossed part 11, the second embossed part 12, the fourth embossed part 33, and the fifth embossed part 34. Thus, it differs from the storage container 31 of the first embodiment. About other structures, such as an outside diameter size and the size of a spout at the time of opening, storage container 40 of comparative example 1 is the same as storage container 31 of Example 1.

  As Comparative Example 2, the storage container 41 shown in FIG. 8 was used. FIG. 8 is a front view showing the storage container of Comparative Example 2. As shown in FIG. 8, the storage container 41 of Comparative Example 2 is different from the storage container 31 of Example 1 in that the first embossed part 11, the second embossed part 12, the fourth embossed part 33, and the fifth The embossed portion 34 is not provided. Furthermore, the storage container 41 of the comparative example 2 has a cylindrical member 43 welded to the inner surface layer of the spout 42.

  About the above-mentioned storage container 31, the storage container 40, and the storage container 41, the extraction | pouring performance of the content was evaluated. Specifically, first, each storage container was filled with 300 g of tap water. Subsequently, the spout was opened, and the storage container was tilted so that the spout faced downward. Thereby, the content (tap water) was poured out by free fall, and the time elapsed from the start of the dispensing of the contents until the dispensing was completed was measured. In addition, the above-mentioned extraction | pouring operation | work was implemented about each storage container by five users. Table 1 shows the measurement results.

  As shown in Table 1, in the storage container 40 of Comparative Example 1, the dispensing flow rate decreased as the content amount decreased. Moreover, in the storage container 40 of the comparative example 1, a spout might be obstruct | occluded in the middle of the pouring of the contents. In the storage container 41 of Comparative Example 2, the flow rate of the extraction differs greatly depending on the user who performed the extraction work, and the variation among the users was large. On the other hand, in the storage container 31 of Example 1, the pouring of the contents could be completed without the pouring flow rate decreasing to the end. Moreover, in the storage container 31 of Example 1, the contents could be poured out more quickly than in the case of the storage container 40 of Comparative Example 1 and the storage container 41 of Comparative Example 2. From the above, in Example 1 using the storage container 31 according to the present embodiment, the contents can be poured out in a state where the dispensing flow rate of the contents is stable without closing the opening of the spout.
