  The above-mentioned pouch of Patent Document 1 is a container that can be manufactured at low cost and is suitable for storing refills. However, once opened, the spout remains open, so all the stored items must be used up. There is an inconvenience of having to. When a part of the stored item is used, it is possible to store it by means such as folding the spout opening part and fastening it with a clip, but the opening part is not sufficiently closed, and the stored item leaks, or There is a possibility of causing inconveniences such as oxidation of stored items, and in any case, it is not suitable for storage after opening.

  In addition, the latter is the presence of the cap even after opening, and can be stored without causing the inconvenience described above even if a part of the stored item is used, but the spout and cap must be molded as a separate member, In addition, it must be liquid-tightly fused at the time of bag making, which is complicated in production and increases the cost.

  The present invention has been made in view of the above points, and the body and spout can be integrally formed by blow molding or the like, and can be manufactured inexpensively and easily. Since the spout discharge path can be liquid-tightly closed, it is possible to partially use the stored items, which enables stable storage of the stored items after opening, and a convenient container for handling. To do.

  A first means is a synthetic resin container in which a cylindrical spout 6 whose tip is closed is projected from a body portion 2 provided with a filling port 3 that is closed after filling with a storage item, and a discharge valve is provided at an intermediate portion of the spout 6. The discharge valve A is a hollow body having a pair of dish-shaped substrates 11 and a dish-shaped reversing plate 12 with an annular fold line 10 as a boundary, and the substrate 11 has an outlet of the spout base end portion 6a. 13 and the inlet 14 of the spout tip 6b are opened, and when the reversing plate 12 is reversed to the inner surface of the substrate 11 by pressing, the outlet 13 and the inlet 14 are closed and reversed by the hydraulic pressure by the body 2 squeezing The reversing plate 12 is configured to be pushed out and discharged, and in addition to the spout 6 provided with the discharge valve A, a cylindrical auxiliary with a closed end for discharging liquid from the body 2. Spout 15 was projected.

  Since the container of the present invention is a simple container for refilling as one purpose application, it is preferable to form it relatively thin, and the form of the body part 2 may not be able to stand up like a normal pouch. Alternatively, it may be in the form of a bag that can stand up like a standing pouch, or in the form of a bottle, and various selections can be made. In addition, the wall thickness can be set up so that it can stand up when standing up, and can be as thick as a normal pouch when in hanging mode. The thickness can be selected. Furthermore, the container may have a single-layer structure of a synthetic resin, or may have a laminated structure appropriately selected according to the purpose of providing gas barrier properties. Further, the form of the substrate 11 and the reversing plate 12 of the discharge valve A can be preferably a spherical plate as shown in the embodiment, but is not limited to this, and the reversal is possible via the folding line 10 and both are hollow bodies. And the outlet 13 and the inlet 14 may be closed when they are further reversed.

  As a second means, in the first means, the tip of the spout 6 is formed in a cap 8 that can be cut out through a thin broken portion 7. A handle 9 may be provided on the cap 8 as a means that can be cut off, and various forms of the handle 9 can be employed.

  As a third means, a suspending means is provided in either the first means or the second means. Examples of the suspending means include making a suspending hole 4 in the body 2 or defining a suspending ring 19 at the upper end of the filling port 3. In the former case, it is possible to store the hanging hole 4 by suspending the hanging hole 4 on a wall hook or the like by attaching an annular hanging strap 5 or the like to the hanging hole 4. Is also possible. In the latter case, there is also a manufacturing advantage that the hanging ring 19 can be integrally formed at the time of manufacturing.

  As a fourth means, the whole of the first means, the second means or the third means was formed by blow molding. Blow molding can employ general blow molding.

  In the container of the present invention, the discharge path of the opened spout 6 can be liquid-tightly closed due to the presence of the discharge valve A, and the body 2 is squeezed when discharging the stored items. The operation can be performed in the same manner as a container of the kind, and if the squeezing of the body part 2 is released, the discharge valve A is automatically closed and the discharge path is shut off, so that the operation is simple and the stored items are divided and discharged Can be used and can be stored after opening.

  Further, if the tip of the spout 6 is formed on the cap 8 that can be cut off through the thin broken portion 7, the spout 6 can be easily opened without using a tool such as a cutter.

In addition to the spout 6 provided with the discharge valve A, a cylindrical auxiliary spout 15 whose end is closed from the trunk portion 2 is projected so that the stored items can be used separately. Since the diameter of the spout 6 and the auxiliary spout 15 can be selected, for example, the diameter of the spout 6 can be set to a suitable diameter for sorting. There is an advantage that the diameter of the spout 15 can be selected according to the diameter of the container for refilling.

  Further, when the suspending means is provided, the suspending means can be stored and the handling becomes more convenient.

  When the whole is formed by blow molding, the whole can be formed integrally, and since it is easy to form in the form of a thin refill container, there is an advantage that it can be manufactured inexpensively and easily.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 to 3 show an example of the container of the present invention. The container 1 is integrally formed of synthetic resin, and the body 2 for storing the contents is recessed in a mountain shape at the bottom. It is configured to be able to maintain a standing state by being expanded by filling the stored items. A filling port 3 is provided at the upper end of the body portion 2 so as to be closed after the stored item is filled. The closing means fusing Ru can be preferably used.

  Further, a cylindrical spout 6 is integrally projected on the body 2, and a cap 8 that can be cut off through a thin broken portion 7 is provided at the tip of the spout 6. A handle 9 is formed integrally with the cap 8, and the break portion 7 is broken by grasping and pulling the handle 9, and the cap 8 is removed to open the tip discharge port of the spout 6. The tip of the spout 6 is not limited to the one provided with the cap 8 as shown in the figure, but may be closed by a wall portion integrally extending from the spout 6, and in that case, the tip portion is cut with a blade or the like. And opening the tip discharge port.

  In the present invention, a discharge valve A is provided in the middle part of the spout 6. The discharge valve A is a hollow body having a pair of dish-shaped substrates 11 and a dish-shaped reversing plate 12 with an annular fold line 10 as a boundary. The substrate 11 has an outlet 13 and a spout tip at the spout base end 6a. The inlet 14 of the part 6b is opened. As shown in FIG. 3 (a), the discharge valve A has a hollow body state in which the substrate 11 and the reversing plate 12 are separated during molding, and the outlet 13 and the inlet 14 are open, and the spout base end portion 6a and the spout tip end portion 6b are opened. Are communicated with each other through a space formed by the substrate 11 and the reverse plate 12. After the opening, as shown in FIG. 3 (b), when the reversing plate 12 is reversed to the inner surface of the substrate 11 by pressing, the outlet 13 and the inlet 14 are closed by the reversing plate 12, and the base end portion 6a and the distal end portion 6b of the spout 6 are closed. And communication is cut off. Moreover, when the trunk | drum 2 was squeezed in this state, it comprised so that the inversion board 12 reversed by the hydraulic pressure might be expanded and poured out.

  In the case of this example, first, the stored material is injected from the filling port 3, and then the wall portion forming the filling port 3 is fixed by an appropriate fixing means such as fusion and closed to form the seal portion a. Can be filled. When used, the cap 8 of the spout 6 may be removed, and the barrel 2 may be squeezed out to discharge the stored items, or the reversing plate 12 may be removed after the cap 8 is removed or before the cap 8 is removed. When the body part 2 is squeezed after closing the outlet 13 and the inlet 14 by pressing the pressure, the closed part of the reversing plate 12 is expanded by the hydraulic pressure, and the stored items can be discharged from the discharge port at the tip of the spout 6. Further, if the squeezing of the body 2 is released, the reversing plate 12 is in the closed state of the original outlet 13 and inlet 14.

In this example, in addition to the spout 6 provided with the discharge valve A, an auxiliary spout 15 is projected from the body 2. The auxiliary spout 15 also includes a cap 18 with a handle 17 through a thin broken portion 16. The unsealing means is the same as the spout 6. In this case, as in the case of the spout 6, the tip of the auxiliary spout 15 may be closed with a wall portion integrally provided without providing the cap 18. In the case of this example, it is suitable for refilling all of the stored items at once. By providing this auxiliary spout 15, the container can be used for a portion of the stored items and the entire stored items can be refilled all at once. Can be used selectively in some cases. In this example, a hanging ring 19 is defined at the upper end of the filling port 3. The suspending ring 19 is formed with a kerf 20 in parallel with a predetermined width from the upper end edge of the filling port 3, and the upper part thereof is configured as a suspending ring 19.
