Description

The present invention, when changing packed contents into a container provided with a dispensing nozzle, spout nozzle container with refill port member is set to be used attached to the Refill pouches, and該詰re port member The present invention relates to a method for refilling used contents.

  In recent years, in consideration of the environment, for example, in bottle containers and dispensing containers that contain fluid contents such as liquids, viscous bodies, and powders, the contents can be used without being discarded even after the contents have been used up. It is desired to use the product for a long time while refilling it. Pouches are frequently used as refill containers that contain the contents to be refilled in these containers. The refill pouch is formed, for example, as a simple bag-like container by laminating two side wall films while preferably sandwiching the bottom wall film to provide self-supporting properties and sealing the peripheral edge portion The contained contents are poured out into a container from a dispensing opening formed by cutting off a tip portion of a spout portion provided at a peripheral portion.

  Further, as a refilling pouch that can be easily transferred to a bottle container or the like, for example, a refilling pouch in which a reinforcing member is thermally bonded to a dispensing opening as in Patent Document 1, As described above, a refilling pouch in which the nozzle receiving portion of the container is bonded to the pouch has been developed so that the refilling of the container having the dispensing nozzle can be performed freely.

On the other hand, in order to accurately extract the contents to a desired position by setting a point from a container containing fluid contents such as liquid, viscous body, powder, etc., while providing an extraction nozzle in the container, It is preferable to squeeze the section of the dispensing nozzle toward the tip. For this reason, forming the extraction nozzle into a tapered shape, for example, has been performed (see, for example, Patent Document 3).

  When refilling the contents from a refilling pouch into a container equipped with a dispensing nozzle, for example, a cap with an integrally formed dispensing nozzle is difficult to remove from the mouth of the container body, and the upper end opening of the container body is opened. If it is not possible to transfer the contents via the dispensing nozzle, the contents should be refilled from the refilling pouch to the container body via the dispensing nozzle. Is required.

  However, even when trying to refill the contents from the refilling pouch into the container body via the dispensing nozzle, especially when the dispensing nozzle has a tapered shape with a reduced cross-sectional area toward the tip. It is difficult to allow the contents to flow into the container from the dispensing opening of the refilling pouch. In addition, it is difficult to insert the container dispensing nozzle into the dispensing opening of the refilling pouch because the dispensing opening is small and the area around the dispensing opening is easily deformed. Even if it can be inserted into the dispensing opening of the refilling pouch or connected, it is easy to create a gap in the connecting part and the connected state is unstable, so the contents are not filled during the refilling operation. There is a risk of spilling or leaking from the gap.

  Furthermore, containers equipped with a dispensing nozzle are reused while refilling their contents, but refilling pouches are not generally reused as pouches, so they are discarded after their contents are refilled. Therefore, there is a demand for resource saving and high productivity by forming a simple form suitable for the purpose.

The present invention makes it possible to easily refill the contents from the refilling pouch into the container through the pouring nozzle provided in the container, and at the same time saves resources and increases the productivity of the refilling pouch.

Yes. Also by these intermittently provided locking flanges 33 and locking ribs 34, the refill port member 32 a is excessively inserted into the spout portion 14 by being abutted and locked to the opening edge portion of the spout opening 16. It is possible to effectively exhibit the function of avoiding the above and the function of positioning and holding the refill port member 32b by being locked by the locking recess 25 provided in the spout portion 14.

In the nozzle with the container 18 of the present embodiment is Refill port member 20 having the above structure is mounted, as shown in FIG. 5, refilling port member 20, the container 18 with a tapered shape of the pouring nozzle 17 It is detachably mounted along the outer peripheral surface of the dispensing nozzle 17 and is commercialized as a container with a nozzle together with the container 18. In addition, the user uses the contents stored in the container body 18a while measuring while pouring an appropriate amount of the contents into the measuring cap 22 with the refill port member 20 attached to the dispensing nozzle 17, for example. To do.

  When the content stored in the container body 18a decreases, the refill port member 20 is removed from the dispensing nozzle 17 and attached to the spout 14 of the refilling pouch 10 to refill the content. That is, after forming the extraction opening 16 by cutting off the tip end portion 14a of the outlet 14 of the refilling pouch 10, as shown in FIG. Is inserted and arranged inside the spout portion 14. Further, the dispensing nozzle 17 of the container 18 is inserted into the refilling port member 20 disposed in the spouting part 14 so that the outer peripheral surface thereof is brought into close contact with the inner peripheral surface of the refilling port member 20, and in this state the clogging is performed. By tilting the replacement pouch 10, the stored contents for refilling are poured out into the container 18 through the dispensing nozzle 17.

  And according to this embodiment, the content can be easily refilled to the container 18 from the refilling pouch 10 via the pouring nozzle 17 provided in the container 18. That is, according to the present embodiment, the refill port member 20 has a shape retaining rigidity that is inserted into the spout port 14 and holds the spout port 14 in a cylindrical three-dimensional shape, and the spout nozzle 17. Since the refill port member 20 is inserted and arranged in the spout portion 14, the flow path 19 by the spout portion 14 that is easily deformed made of a film material is blocked. It becomes possible to hold firmly as a hollow part without making it. Further, the refilling port member 20 inserted and arranged in the spout port 14 can be used as a guide, and the spout nozzle 17 can be quickly inserted into the spout port 14 and the outer peripheral surface of the spout nozzle 17 can be refilled. Since it can be easily brought into close contact with the inner peripheral surface of the member 20, the contents can be efficiently poured into the container 18 from the refilling pouch 10 in a stable state without causing the contents to leak out. It becomes possible.

  Moreover, according to this embodiment, it becomes possible to achieve resource saving and high productivity of the refill pouch 10. That is, according to this embodiment, the refilling pouch 10 is provided with the refilling port member 20 for firmly holding the flow path 19 by the spout port 14 made of a film material, which is easily deformed, as a hollow part. Since it is formed as a separate member that can be detached from the spout 14 and can be easily removed from the refilling pouch 10 and stored without being integrally joined to the refilling pouch 10, the mouth member is integrally joined to the refilling pouch 10 It is possible to form the refilling pouch 10 with the same simple structure as a general one without requiring a process, and the mouth member can be reused without being discarded together with the refilling pouch 10. Therefore, it is not necessary to wastefully form the refill port member 20, thereby refilling and saving resources without complicating the production process of the refill pouch 10. It is possible to achieve both reduction.

The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, the contents accommodated in the refilling pouch do not necessarily need to be a liquid detergent, and may be other liquids such as liquid food, or other fluidity such as mucilage and powder. . The nozzle with the container of the present invention the contents are changed packed is not limited to a liquid dispensing container having the function of weighing the contents may be a variety of other container with a dispensing nozzle . Furthermore, the pouring nozzle does not necessarily have a tapered shape, and the shape of the refill port member can be appropriately changed according to the shape of the outer peripheral surface of the pouring nozzle.

Furthermore , for example, as shown in FIG. 9 , the refill port member 20 includes a spout portion 14 ′ of the refill pouch 10 b in which the flow path 19 ′ from the storage portion 13 toward the discharge opening 16 is not formed in a tapered shape. It can also be inserted into and used. In such a case, a gap is generated between the outer peripheral surface of the refill port member 20 and the inner peripheral surface of the spout port portion 14 ′. For example, the peripheral portion of the spout opening 16 is blocked by the locking flange 23. By doing so, it is possible to avoid leakage of the contents and the like, so that the substantially same effect as the above-described embodiment is exhibited.
