  Since the refill container described in Patent Document 1 uses two members, a coupling member and a container sealing member, in the cap portion in order to combine the reusable container and the refill container, the cost of the container is low. It must be expensive. In addition, since the refill container is used by repeatedly screwing it into the opening of the container to be used, the connection between the two is reliable, but on the other hand, it is not only troublesome to operate but also disadvantageous in terms of the cost of the plug. There was a drawback of being.

  On the other hand, recently, from the standpoint of product safety, nozzles with sharp tips have been avoided, and containers with flat nozzle tips have become mainstream. If you try to open the refill container seal with the tip of a flat nozzle, it is necessary to design the seal break strength to be weak, but if the seal break strength is weakened, the refill container body is made of a flexible packaging film. If the container is an unsafe container, there is a possibility that when the refill container is subjected to external force or the refill container is dropped, the seal may rupture and the contents may leak. found.

  The problem to be solved by the present invention can also be applied to a container having a nozzle with a flat tip, and even when pressure is applied to the container or when the container is dropped, the content does not leak, The present invention proposes a one-touch opening type soft packaging bag refill container stopper and a refill container using the same.

As a means for solving the above-mentioned problems, the invention according to claim 1 is a plug of a refill container used for replenishing a rigid container having a dispensing nozzle, which is refilled. It has a cylindrical spout part to be used by inserting a container body mounting part for fixing the container body and a nozzle for dispensing a rigid container,
The spout part has a cross-sectional shape into which the dispensing nozzle of the rigid container is fitted,
A seal plate for sealing the container is fixed to the end of the spout portion on the side of the refill container body, and the seal plate is sealed by the seal plate. It is protected from the refill container internal pressure by the seal plate protector joined to the inner wall of the spout part by the part ,
The inner wall joint portion and the seal plate are configured so as to be broken by insertion of the dispensing nozzle .

The invention according to claim 2 is the plug for the refill container according to claim 1 , wherein the seal plate protector has a structure in which thin bars are combined.

The invention according to claim 3 is the refill container plug according to claim 1 or 2 , further comprising an overcap covering the cylindrical spout portion.

Moreover, invention of Claim 4 is the refill container characterized by using the spigot of any one of Claims 1-3 .

  The refill container cap according to the present invention is provided with a seal plate protector for protecting the seal plate from the internal pressure of the refill container in the immediate vicinity of the seal plate. In addition, even when the internal pressure of the refill container is increased by dropping the refill container, the seal plate does not burst and the contents do not leak out.

  Further, the refill container stopper according to the present invention has a structure in which the seal plate protector is joined to the inner wall of the spout part by a small area inner wall joint part. Since the tip of the dispensing nozzle is easily broken, the opening of the seal plate is not hindered. Therefore, when the refilling operation is performed, the refilling can be performed by an extremely simple operation by simply inverting the refilling container and inserting the pushing-out nozzle of the rigid container into the spout portion and pushing it.

  In addition, the seal plate protector has an effect of preventing the broken seal plate from being covered with the dispensing nozzle of the rigid container.

  Further, when the spout portion has a cross-sectional shape into which the ejection nozzle of the rigid container is fitted, the refill container is set at a normal position with respect to the rigid container, and the refill container Can be adjusted so that the gap between the container and the rigid container is optimal, so that the contents do not overflow or pop out during the refilling operation It is.

  Moreover, when the plug for a refill container has an overcap that covers the cylindrical spout part, dust can be prevented from entering the inside of the spout part. If the overcap is fixed with a screw, the remaining use can be sealed and stored safely.

Still further, the refill container spigot according to the present invention comprises a container main body mounting part for fixing the refill container main body, a cylindrical spout part into which the dispensing nozzle for the rigid container can be inserted, and a spout part. Since the seal plate protector joined to the inner wall can be integrally molded, the number of parts can be reduced and the production can be efficiently performed.

  The plug 1 according to the present invention is a plug for a refill container used for replenishing the contents of a rigid container having a dispensing nozzle, and a container body mounting portion for fixing the refill container body 2 and a cylindrical spout portion 3 into which the dispensing nozzle for the rigid container can be inserted, and the end of the spout portion on the side of the refill container body is sealed by a seal plate 5 for sealing the container, The plate 5 is provided in the immediate vicinity of the seal plate 5 and is protected from the internal pressure of the refill container by the seal plate protector 6 that is joined to the inner wall of the spout part by the inner wall joint 7 having a small area.

  The container main body mounting part 2 is a part at the lower part of the spout part 3 and to which a refill container main body made of a flexible packaging film is fixed. As a fixing method, a heat fusion method is generally used. The container body mounting portion 2 has a spindle shape so that the container body can be easily fused. Although not shown, a plurality of ribs are provided in the lateral direction to improve the meltability with the film.

  The spout part 3 has a cylindrical shape that can be inserted into a dispensing nozzle of a rigid container that is repeatedly used. In this embodiment, although it is a column shape, it is good also as a shape which just fits this according to the cross-sectional shape of the nozzle for extraction of the target rigid container. The end of the spout portion 3 on the refill container main body side is sealed by a seal plate 5 that seals the container.

The seal plate 5 seals the refill container and needs to be easily opened by the tip of the dispensing nozzle of the rigid container that is repeatedly used. Specifically, an aluminum foil alone or a material obtained by laminating a thermoplastic resin film on an aluminum foil is preferably used. The seal plate 5 is fixed to the end of the spout portion 3 on the refill container main body side, that is, the bottom surface of the container main body mounting portion 2 by heat fusion or an adhesive.

  The seal plate protector 6 is provided in the immediate vicinity of the seal plate 5 and plays a role of protecting the seal plate 5 from pressure applied to the inner surface of the seal plate 5 from the refill container body. Since the seal plate protector 6 is joined to the inner wall of the spout portion by the inner wall joint portion 7 having a small area, the inner wall joint portion is easily broken when pushed by the nozzle for pouring the rigid container. Further, the seal plate 5 is broken and the refill container body is opened. The shape of the seal plate protector 6 is a cross shape in this embodiment, but is not particularly limited as long as the seal plate protection and the easy-openability at the time of opening are satisfied.

  The spigot 1 is molded once by an injection molding method using a thermoplastic resin such as polyethylene resin, polypropylene resin, polyester resin, etc., with the container body mounting part 2, spout part 3 and seal plate protector 6 integrated. Can be molded.

  FIG. 3 is a schematic cross-sectional view of a refill container according to the present invention using the spigot shown in FIG. A refill container body 4 made of a flexible packaging film is fused to the container body mounting portion 2 of the stopper 1. The container shown in FIG. 3 is a so-called standing pouch composed of two soft wrapping films on the front and back and a soft wrapping film constituting the bottom surface. Since the spigot 1 is sealed in advance by the seal plate 5, in order to fill the contents of the refill container body, after filling the refill container body 4 with the contents, Alternatively, when the plug 1 is fixed to the refill container body, a part of the peripheral seal 9 of the refill container body 4 is left unsealed, and after filling the unsealed portion with the contents, the unsealed portion is removed. Either sealing or either method is adopted.

  Although it does not restrict | limit especially as the refill container main body 4, The soft packaging bag made from the soft packaging film which compounded the thermoplastic resin film, the container which consists of a composite material of a thermoplastic resin film and paper, etc. Can be used. The container is completed by fixing the thermoplastic resin layer on the inner surface of the container and the container body mounting portion 2.

  FIG. 4 is an explanatory cross-sectional view showing the refilling operation from the refill container shown in FIG. 3 to the rigid container to be used repeatedly. A nozzle cap 11 attached to the rigid container body 10 to be used repeatedly is provided with a nozzle 12. To refill the container, the refill container is inverted and inserted into the nozzle 12 so as to cover the spout portion 3 of the plug 1 of the refill container. FIG. 4 shows a state in which the refill container is inverted, the nozzle 12 of the rigid container body 10 is inserted into the spout 3 of the spigot 1, and the seal plate protector 6 and the seal plate 5 are broken by the nozzle tip 13. It is a thing. Thereby, the content falls in the direction of the arrow 14 indicating the content inflow direction, and moves to the rigid container body 10. At this time, the seal plate protector 6 does not break all of the inner wall joint portion 7 at the same time, the portion where the nozzle tip 13 first hits as shown in the figure, and the spout portion does not break on the opposite side. 3 is attached to the inner wall. For this reason, the seal plate protector also exhibits an effect of preventing the seal plate 5 from covering the nozzle tip 13 and blocking the flow path of the contents.

  As described above, the refill container using the plug for the refill container according to the present invention has an extremely simple operation in which the spout portion of the refill container is inserted and pushed into the nozzle portion of the rigid container that is repeatedly used. Since the refilling is completed and the force for pushing in does not require a strong force, anyone can easily perform the refilling operation without failure.

FIG. 5 is a schematic plan view showing another embodiment of the plug for a refill container according to the present invention. In this embodiment, the spout part 3 of the spigot 1 is not a columnar shape but an elliptical column shape. In this case, the cross-sectional shape of the spout portion 3 is a cross-sectional shape into which the spout nozzle of the target rigid container is fitted. By doing in this way, in the case of a refilling operation, the inverted refilling container is stabilized without shaking, so that the refilling operation can be performed more smoothly and safely.

  6 and 7 are schematic plan views showing other embodiments of the refill container stopper according to the present invention. In the spigot 1 shown in FIG. 6, the shape of the seal plate protector 6 is such that two regular triangles are combined. In the embodiment shown in FIG. There are 6 places compared to 4 places. Moreover, since the seal plate protector 6 is uniformly arranged with respect to the seal plate 5, the seal plate protection effect is further enhanced. In the spigot 1 shown in FIG. 7, since the seal plate protector 6 is arranged in a lattice shape, the number of inner wall joints 7 is increased to 12 and the density of the seal plate protector 6 to be arranged is also increased. Therefore, the protective effect of the seal plate is further improved. However, since the ease of breakage during the refilling operation is reduced, it is necessary to pay attention to the balance with the nozzle tip shape of the rigid container.

  FIG. 8 is a schematic cross-sectional view showing another embodiment of the plug for a refill container according to the present invention. In this embodiment, an overcap 8 that covers the spout portion 3 of the spigot 1 is provided. Due to the presence of the overcap 8, it is possible to prevent dust and the like from entering the spout portion 3 during the display of the product and reducing the product value. In addition, when the overcap is screwed, re-sealing is possible even when the contents of the refill container are left over.
