Description

  The present invention relates to a container capable of storing liquid contents, and more particularly to a spout-equipped container to which a spout for taking out liquid contents stored without opening the container is attached.

  Glass containers, plastic bottles, cans and the like have been generally used as containers for storing alcoholic beverages such as wine and sake. The same applies to containers that contain other liquid contents such as seasonings, cosmetics, shampoos, and detergents.

  On the other hand, in recent years, packaging bags (so-called pouch bags) formed by heat-sealing plastic films with low production costs are often used as packaging bags used for such liquid contents, particularly refillable products. In addition, as disclosed in, for example, Patent Document 1 and Patent Document 2, a spout-equipped container in which a spout (a spout member) is attached to a pouch bag type container has been proposed.

Japanese Patent Laid-Open No. 11-029156 JP-A-11-059702

  Containers with spouts can be changed to mineral water, seasonings, liquid foods, shampoos, detergents, cosmetics, etc. by changing the design of the container itself, the shape of the spout, the internal volume, the structure of the laminated film used as the container material, etc. Although it is used for various liquid contents, it is rarely used for alcoholic beverages such as sake and wine. This is because sake, wine, and the like once have the problem that air enters the container once it is opened, and the flavor is significantly impaired by oxidation.

  The present invention has been made in view of such points, and even when liquid contents that are easily oxidized by air such as sake or wine are contained, the quality of the contents is deteriorated due to oxidation. The aim is to provide a container with no spout.

  In order to solve the above-mentioned object, the present invention provides a container with a spout comprising a self-supporting container body made of a flexible film laminate and a spout for pouring out the contents contained in the container body. The spout is attached to the lowermost part of one side surface of the container body, and has a structure capable of repeatedly opening and closing a spout for pouring the contents out of the container. A container is provided (device 1).

  According to the above device (device 1), since the spout is attached to the lowermost part of one side surface of the container body, when the container body is made self-supporting in the state of containing the contents and the spout of the spout is opened, the contents The contents are poured out of the container by its own weight, and when the spout outlet is closed, the contents are not poured out of the container. During the opening and closing operation of the spout, since the contents themselves prevent the air from entering the container body, liquid contents that are easily oxidized by air such as sake and wine are accommodated in the container body. Even in this case, the quality of the content is not deteriorated due to oxidation.

  In the above device (device 1), the spout has a spout body portion having a path through which contents flow from the container body to the spout, a closing member made of an elastic material that closes the spout, and the closing It is preferable to include an operation member that opens the spout by deforming the member (device 2).

  According to the above invention (Invention 2), as long as the operating member is operated, the outlet can be opened or closed by deforming the closing member made of an elastic material. It is possible to easily realize a structure in which a spout for pouring out an object can be opened and closed repeatedly.

  In the above devices (devices 1 and 2), it is preferable that the container body has a standing pouch structure in which the pouch side wall portion and the pouch bottom portion are heat sealed (device 3). According to the said device (device 3), even if the container body is made of a flexible film laminated material, a structure capable of being easily self-supported can be obtained.

  In the above device (devices 1 to 3), it is preferable that the container body can be folded into a sheet shape (device 4) when the container body does not contain the contents. According to the above idea (invention 4), since it is in a very compact shape in the state where the contents are not accommodated, it is possible to save space in the factory, and on the consumer side such as each home, Since the size can be gradually reduced during use, it is not necessary to increase the storage space, and it is not bulky when discarded after use.

  In the above devices (devices 1 to 4), it is preferable that a grip portion is provided at the uppermost part of the container body (device 5). According to the said device (device 5), even when the contents are accommodated, it can be easily carried by grasping the grip portion by hand.

  According to the spouted container according to the present invention, the contents themselves prevent the air from entering the container body even when liquid contents that are easily oxidized by air such as sake or wine are contained. The quality of the contents is not deteriorated due to oxidation.

It is an external appearance explanatory drawing showing roughly the structure of the spout of the container with a spout concerning the embodiment. It is a disassembled sectional view which shows roughly the structure of the spout of the container with a spout concerning the embodiment. It is explanatory drawing which shows the mode of a deformation | transformation of the sealing member of the spout of the container with a spout concerning the embodiment.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory view schematically showing the structure of a spouted container 1 according to this embodiment, in which FIG. 1 (a) is a front view and FIG. 1 (b) is a side view. As shown to Fig.1 (a) and (b), the container 1 with a spout which concerns on this embodiment is the container main body 2 which consists of a flexible film laminated material, and the content accommodated in the container main body 2 And a spout 3 for dispensing C. As the content C in the present embodiment, an alcoholic beverage that is easily oxidized by air such as sake or wine is kept in mind, but is not limited to this, and the spouted container 1 according to the present embodiment includes the content The product C can be stored in any liquid content such as beverages such as mineral water and juice, seasonings, liquid foods, shampoos, detergents, cosmetics and the like.

  As shown in FIG. 1B, the container body 2 has a standing pouch structure in which the first pouch side wall portion 21, the second pouch side wall portion 22, and the pouch bottom portion 23 are heat sealed. Therefore, it has a self-supporting structure. The first pouch side wall part 21, the second pouch side wall part 22, and the pouch bottom part 23 are all manufactured by molding a flexible film laminate having the same configuration. As a flexible film laminated material, for example, as shown in FIG. 2A, a PET (polyethylene terephthalate) layer having a thickness of 12 μm, a printing layer, an adhesive layer, an aluminum deposited film layer having a thickness of 0.5 μm, an adhesive A layer formed by laminating an agent layer and an LDPE (low density polyethylene) layer having a thickness of 150 μm in this order, or a PET (polyethylene terephthalate) layer having a thickness of 12 μm, a printing layer, and an adhesive as shown in FIG. Layer, 9 μm thick aluminum film layer (aluminum foil), adhesive layer, 15 μm thick OPA (biaxially oriented polyamide) layer, 150 μm thick LDPE (low density polyethylene) layer in this order Is mentioned.

  Since the container main body 2 is a container having a standing pouch structure made of a flexible film laminated material, the container main body 2 can be folded into a sheet shape when the container main body 2 does not contain the contents C. For this reason, it becomes a very compact shape in a state where the contents C are not accommodated, so that it is possible to save space in the factory, and on the consumer side in each household, the size is gradually reduced during use. Therefore, it is not necessary to take up a large storage space, and it is not bulky when discarded after use.

  In the lowermost center of the first pouch side wall portion of the container body 2, a circular opening (not shown) used for taking in and out the liquid content stored in the container body 2 is provided. A plastic ring member 24 is fitted.

  As shown in FIGS. 3 and 4, the spout 3 includes four members: a spout body 31, a cap member 32, a lever member 33, and a seal member 34. 3 and 4, (a) is a front view and (b) is a side view. By pulling up the lever 331 of the lever member 33 upward, the plug portion 341 of the seal member 34 closing the spout 316 is lifted upward, the spout 316 is opened, and the contained content C is stored in the container. It flows out from the main body 2 through the spout 3 to the outside of the container. The spout 3 is connected to the container main body 2 by fitting a cylindrical mounting portion 311 provided on the spout main body 31 with the ring member 24 of the container main body 2. The specific structure of the spout 3 and each member will be described later.

  There are three circular handle holes 4a in the center of the uppermost portion of the container body 2 (the center of the region of about 4 cm width where the first pouch side wall and the second pouch side wall are integrated by heat sealing). , 4b, 4c are formed in a row in the horizontal direction. Since the spouted container 1 can be firmly held by hand by passing a finger through the three handle holes 4a, 4b, 4c, it can be easily carried even in a state where the contents C are accommodated. In the present embodiment, three circular handle holes are provided. However, the present invention is not limited to this. For example, one oval handle hole may be provided in the center of the uppermost portion of the container body 2.

  Next, the structure of the spout 3 will be described in detail. As described above, the spout 3 is composed of four members: the spout main body 31, the cap member 32, the lever member 33, and the seal member 34. The spout body 31, the cap member 32, and the lever member 33 are made of plastic, and the seal member 34 is made of an elastic material such as an elastomer or silicon rubber.

  The spout body 31 has a hollow cylindrical attachment part 311, a disk-shaped fringe part 312, and a hollow rectangular parallelepiped shape, and the contents C distributed from the container body 2 via the attachment part 311 to the body part 314. And a body portion 314 having a hollow cylindrical shape tapered downward and having a spout 316 provided at the lowermost portion. Notches necessary for moving a lever 331 of a lever member 33 to be described later are provided as lever member movable spaces 315 on both uppermost side surfaces of the body portion 314.

  The cap member 32 includes a disk part 321 for closing the opening on the upper surface of the body part 314 and two pressing parts 322 extending vertically downward from the disk part 321 and has a π-shape in side view. doing.

  The lever member 33 has a combination of a conical portion 333 and a cylindrical portion 334 that taper downward, and a pair of left and right levers 331 are provided on the upper portion. A projecting locking portion 332 is provided extending from the lower surface of the conical portion 333 to hold the seal member 34.

  The sealing member 34 has a shape in which a cylindrical plug portion 341 that closes the spout 316 protrudes from a lower surface of a bowl-shaped deformable portion 342, and a locking portion 332 of the lever member 33 is formed at the center of the plug portion 341. A small hole (not shown) to be fitted is provided to open on the plug portion 341 side. The lever member 33 and the seal member 34 are integrated by inserting the engaging portion 332 of the lever member 33 into the small hole from the deformable portion 342 side to be engaged.

  The integrated lever member 33 and seal member 34 are sandwiched between the cap member 32 from the upper side and the spout body 31 from the lower side, and the portion where the disk portion 321 of the cap member 32 contacts the spout body 31 is fixed, thereby fixing the spout body. The spout 3 is formed by integrating four members 31, a cap member 32, a lever member 33, and a seal member 34. At this time, the lever 331 of the lever member 33 enters between the two holding portions 322 of the cap member 32 and enters between the lever member movable spaces 315 on both side surfaces of the spout body 31. ing.

  In the integrated state, the plug portion 341 of the seal member 34 closes the spout 316 at the bottom of the spout body 31. Further, the lower ends of the two holding portions 322 of the cap member 32 are in contact with the edge of the deformable portion 342 of the seal member 34, and the deformable portion 342 can move further upward in the spout 3. I can't do it.

  The movement of each member when the lever 311 of the spout 3 is operated (when the spout 316 is opened) will be described. When the lever 311 is moved upward while pressing the disk portion 321 of the cap member 32, the entire lever member 33 is also moved. Since it tries to move upward, the locking portion 332 naturally moves upward. The locking portion 332 engages with a small hole provided in the plug portion 341 of the seal member 34, and the lever member 33 and the seal member 34 are integrated, so that the seal member 34 also moves upward. This power will work.

  However, the lower ends of the two retaining portions 322 of the cap member 32 are in contact with the edge of the deformable portion 342 of the seal member 34, and the deformable portion 342 can move further upward in the spout 3. I can't do it. Therefore, the seal member 34 is in a state where a force that pulls the plug portion 341 upward and a force that presses the opposite deformable portion 342 downward act. Here, the seal member 34 is made of an elastic material, and when the opposite forces are exerted as described above, the connecting portion (the portion having the lowest elastic modulus structurally) between the plug portion 341 and the deformable portion 342 is the center. As shown in FIG. 5, the plug portion 341 moves upward so as to be accommodated in the deformation portion 342. That is, the spout 316 is opened because the plug portion 341 that has blocked the spout 316 moves upward in the spout 3.

  In the present embodiment, since the spout 3 is attached to the lowermost part of one side surface of the container body 2, the container body 2 is made to stand up in a state in which the contents C are accommodated, and the lever 331 is operated as described above. When the spout 316 of the spout 3 is opened, the content C is poured out of the container by its own weight. Further, when the force for moving the lever 331 upward is loosened, the deformation of the seal member 34 is naturally eliminated by the elastic force of the seal member 34, the plug portion 341 returns to its original position, and the spout 316 of the spout 3 is restored. To stop the content C from being poured out of the container. During the opening and closing operation of the spout 316, the contents C itself prevents the air from entering the container body. Therefore, liquid contents that are easily oxidized by air such as sake and wine are accommodated in the container body. Even if it is, the quality deterioration of the content by oxidation does not arise.

  Conventionally, products in which liquid contents are packed in a pouch bag type container are manufactured through a process of filling the liquid contents from the upper opening of the pouch bag and heat-sealing the upper opening after filling. In order to heat seal the opening in a state where the container is filled with the liquid content, a very complicated mechanical structure of the filling machine is required, and the price of the filling machine itself is increased. Here, in the case of the spouted container 1 of the present embodiment, for example, when the spout 3 is temporarily fastened to the container main body 2 and delivered to the factory as a packaging material, in the liquid content filling machine (step 1) The fastened spout 3 is removed from the ring member 24 of the container main body 2 (Step 2), and the liquid content is filled into the container main body 2 from the relevant location. (Step 3) After the filling, the spout 3 is attached to the container main body 2 again. It is possible to realize the process. In this case, it is not necessary to heat-seal the opening in a state where the container is filled with the liquid content in the filling machine, so the mechanical structure of the filling machine can be made simpler than before and the capital investment can be reduced. There is also a side effect of being able to.

  As mentioned above, although the spouted container 1 which concerns on this embodiment has been demonstrated, this invention is not limited to the said embodiment, A various change implementation is possible.
