  The refill container described in Patent Document 1 uses two members, namely a coupling member and a container sealing member, in the cap portion in order to combine the reusable container and the refill container, so that the cost of the container is high. It must be. 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. In recent years, from the standpoint of product safety, nozzles with sharp tips have been avoided, and containers with flat nozzle tips have become mainstream.

  The problem to be solved by the present invention is to propose a plug for a one-touch opening refillable container made of a single member, which can be applied to a container having a nozzle having a flat tip.

  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 the contents of a rigid container having a dispensing nozzle having a slit. A refillable container plug comprising: a sleeve for fixing a refillable container main body; a cylindrical spout into which the rigid container pouring nozzle can be inserted; and a seal plate for sealing the container.

And a cylindrical spout into which the rigid container pouring nozzle can be inserted, and a sealing plate for sealing the container, and the pouring nozzle is disposed on the inner periphery of the cylindrical spout. A plurality of nozzle positioning ribs that hold the nozzle in a predetermined position and one nozzle slit positioning rib that fits into the slit of the dispensing nozzle, and the seal plate is positioned from the position of the nozzle slit positioning rib. A refill container stopper characterized in that it is provided so as to rise toward the opening of the spout, and an opening score is provided on the outer periphery of the seal plate. .

  The invention according to claim 3 is the plug for a refill container according to claim 1 or 2, wherein a notch-like air vent slit is provided at the tip of the cylindrical spout. .

  Moreover, invention of Claim 4 has an overcap which covers the said cylindrical spout, It is a plug for refill containers of any one of Claims 1-3 characterized by the above-mentioned.

  A refill container spout according to the present invention is a refill container spout used for replenishing the contents of a rigid container having a dispensing nozzle having a slit, and firmly attaches the refill container body. And a cylindrical spout into which the rigid container pouring nozzle can be inserted, and a sealing plate for sealing the container, so that the entire refilling container is turned upside down and cylindrical to the rigid container pouring nozzle. It is possible to complete the refilling operation at a stroke with a single touch.

  According to such a refilling operation, it is possible to apply a sufficient force to the seal plate because the refilling container is simply pressed in the vertical direction, and it is applicable to a container having a nozzle with a flat tip. it can.

  A refill container plug according to claim 2 of the present invention includes a sleeve for fixing a refill container body, a cylindrical spout into which a dispensing nozzle for a rigid container can be inserted, and a seal for sealing the container Since it has a board integrally, it consists of one part, Therefore When producing a refill container, it can produce efficiently.

  Furthermore, the inner periphery of the cylindrical spout is provided with a plurality of nozzle positioning ribs that hold the dispensing nozzle in a predetermined position and one nozzle slit positioning rib that fits into the slit of the dispensing nozzle. Therefore, during the refilling operation, it is possible to set the refilling container at the predetermined position without error with respect to the dispensing nozzle of the rigid container, and conversely, it can be set only at the correct position. Therefore, it is possible for anyone to perform the correct operation and the contents are not accidentally spilled or overflowed.

  Furthermore, since the refill container is set at a normal position with respect to the rigid container, the shape of both can be adjusted so that the gap between the refill container and the rigid container is optimized. It is possible to prevent the contents from overflowing or jumping out during the refilling operation.

  Furthermore, the seal plate is provided so as to rise from the position of the nozzle slit positioning rib toward the opening of the spout, and an opening score is provided on the outer periphery of the seal plate. Therefore, when the refill container is inverted and the rigid container pouring nozzle is inserted into the spout, the rigid container pouring nozzle has the highest position on the opposite side of the nozzle slit positioning rib, that is, the seal plate. Since it is pressed to the position at the beginning, the opening score always breaks from this one point, and the opening starts smoothly, and the opening proceeds smoothly. For this reason, even if the tip of the dispensing nozzle of the rigid container is not sharp and flat, the opening starts more easily.

  In addition, when a notched air vent slit is provided at the tip of the cylindrical spout, the container body is a rigid container such as a bottle and does not deflate like a pouch. However, since the air in the rigid container is discharged smoothly, the gas-liquid exchange is smooth, and the contents do not flow backward or splash.

  In addition, when the refill container cap has an overcap that covers the cylindrical spout, dust can be prevented from entering the spout. If the overcap is fixed with a screw, the remaining use can be sealed and stored safely.

In this example, the refill container body 4 is a flat top type brick-shaped paper container. Thus, as the refill container body 4, a soft packaging bag, a paper container, etc. other than a plastic bottle can be used.

  The seal plate 5 is made of a fragile material so as to be easily broken by the dispensing nozzle of the rigid container. In this example, an aluminum foil having a polyethylene film laminated on both sides can be used. In particular, when a gas barrier property is not required, a single polyethylene film or the like may be used.

  Explaining how to use the refill container using the cap according to the present invention, as shown in FIG. 4 (1), the empty rigid container body 10 is held with one hand and the overcap is removed. The container body 4 is turned upside down so that the nozzle 12 of the rigid container enters the plug 1 of the refill container. FIG. 5A is a cross-sectional view showing this state. Next, as shown in FIG. 4 (2), when the refill container body 4 is pushed downward as in the refill container insertion direction 15, as shown in FIG. 5 (2), the nozzle of the rigid container 12 breaks the seal plate 5 and the refill container is opened.

  Since the contents of the opened refill container fall at once and move to the rigid container, the refill operation is completed in a very short time. Thus, since the refill container using the spigot 1 according to the present invention has the cylindrical spout 3 into which the dispensing nozzle 12 for the rigid container can be inserted, and the seal plate 5 for sealing the container, Such a refilling operation by simply pushing down in the vertical direction is possible. Therefore, the refilling operation can be sufficiently applied to a rigid container having a nozzle whose tip is not sharp and sharp.

FIG. 6 is a schematic view showing another embodiment of the plug for a refill container according to the present invention, (1) is a schematic plan view, and (2) is a schematic cross-sectional view showing the AA cross section of (1). FIG.

  A spigot 1 according to this embodiment includes a sleeve 2 for fixing a refill container body 4, a cylindrical spout 3 into which a dispensing nozzle for a rigid container to be used repeatedly can be inserted, and a seal for sealing the container It is a refill container stopper having the plate 5 integrally. This plug can be formed by a single molding by an injection molding method using a thermoplastic resin such as a polyethylene resin, a polypropylene resin, or a polyester resin.

  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 bottle which shape | molded the thermoplastic resin, a thermoplastic resin film, A container made of a composite material with paper can be used. By fixing the thermoplastic resin layer on the inner surface of the container and the sleeve 2, the container is completed.

  When the refill container body 4 is a soft packaging bag made of a soft packaging film in which a thermoplastic resin film is combined, or a container made of a composite material of a thermoplastic resin film and paper, the heat of the inner surfaces of these containers A method of fixing the plastic resin layer and the sleeve 2 by heat-sealing is generally used. When the refill container main body 4 has a rigid bottle shape, the fixing method of the refill container main body 4 and the stopper 1 is to be fitted with a screw, or as fixed by a stopper as shown in FIG. Also good. In that case, as shown in FIG. 6 (2), it is preferable that the sleeve 2 of the spigot 1 covers the opening of the refill container body 4 also on the outside.

  On the inner periphery of the cylindrical spout 3, a plurality of nozzle positioning ribs 7 for holding the dispensing nozzle in a predetermined position and one nozzle slit positioning rib 6 that fits into the slit of the dispensing nozzle are provided. ing. The nozzle positioning ribs 7 are arranged on the inner circumference of the spout 3 at almost equal angles from the center, and the width of each rib is adjusted according to the cross-sectional shape of the pouring nozzle to be inserted is a deformed ellipse. Is set. In addition, nozzle slit positioning ribs 6 are provided so as to fit in the slits of the dispensing nozzle.

  When the spout 3 is inserted into the nozzle by the action of the nozzle slit positioning rib 6 and the nozzle positioning rib 7, the positional relationship between the nozzle and the spout is determined uniquely, so that both fit closely and are stable. For this reason, in the refilling operation, an operation error that spills or overflows the content liquid does not occur.

  When the inclined surface 9 is formed at the upper end of the positioning rib 7 as in this embodiment, the spout 3 is not caught when inserted into the nozzle, and is smoothly inserted.

  The seal plate 5 that seals the refill container is provided so as to rise from the position of the nozzle slit positioning rib 6 toward the opening of the spout 3, and is opened on the outer periphery of the seal plate 5. A score of 8 is provided. In the present embodiment, the opening score 8 is a V-shaped groove and is provided along the outer periphery of the seal plate 5.

  In this embodiment, four notch-shaped air vent slits 17 are provided at the tip of the spout 3. The air vent slit 17 allows the outside air to enter the container as the contents flow out during refilling when the container body is a container that itself does not wither as the contents flow out, such as a rigid bottle. In order to facilitate gas-liquid exchange. In this embodiment, four places are provided, but one place may be provided. In this case, the most effective position is the upper part of the nozzle slit positioning rib 6. The length of the air vent slit 17 in the height direction is preferably such that when the refill container body is inverted and inserted into the nozzle cap of the rigid container, it does not become higher than the upper end of the opening of the rigid container. .

To refill the container, the refill container is inverted and inserted into the nozzle 12 so as to cover the spout 3 of the plug of the refill container. Since the tip 13 of the nozzle 12 is positioned by the nozzle positioning rib 7 and the nozzle slit positioning rib 6 fitted to the nozzle slit 14, it is inserted in the insertion direction 15 in a predetermined positional relationship. At this time, if the inclined surface 9 is formed at the upper end of the nozzle positioning rib 7, the nozzle tip 13 is not caught and is smoothly inserted.

  Since the seal plate 5 is inclined so as to rise from the position of the nozzle slit positioning rib 6 toward the opening of the spout 3, the tip 13 of the inserted nozzle is accurately positioned on the seal plate 5. The lowest position (when viewed in FIGS. 7 and 8) is first contacted. For this reason, even if the nozzle tip 13 is not sharp and is flat, the nozzle tip 13 starts contact from one point of the seal plate 5, so that the opening provided on the outer periphery of the seal plate 5 is opened. The score for 8 starts to break smoothly from this point. For this reason, the force required for opening can be reduced.

  In addition, the opening of the refill container generated by the breaking of the opening score 8 has a shape that fits the nozzle 12 and is present on the outside so as to cover the spout 3. There is no spillage or splashing of objects.

  As described above, the refill container using the plug for the refill container according to the present invention is refilled by an extremely simple operation of inserting and pushing the spout of the refill container into the nozzle portion of the rigid container to be used repeatedly. Since no force is required to push in, the refilling operation can be performed easily and without failure by anyone.
