Containers have been proposed. This hand-held refillable container is a refillable container including a coupling member that is detachably connected to an opening of a reusable container and cannot be dropped off, and a container sealing member that seals the refillable container body (see Patent Document 1).

JP 2004-99082 A

  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.

  On the other hand, since the nozzle of a rigid container that is used repeatedly needs to have a certain size for ease of use, the plug of a refill container that has a plug that fits into the nozzle also has a considerable size. However, when refilling, there is a problem that a large amount of contents flow out from the large-diameter plug at once, and cannot repeatedly enter the container and overflow outside the container. I found out.

  The problem to be solved by the present invention is to propose a one-touch opening refill container that has a simple structure, is easy to refill, and does not overflow the contents during the refill operation.

As a means for solving the above-mentioned problems, the invention according to claim 1 is a refill container used for replenishing a rigid container having a dispensing nozzle with a refill container body. And a stopper, and the stopper has a sleeve for fixing the refill container body, a spout into which the nozzle for dispensing the rigid container can be inserted, and a seal plate for sealing the refill container. and, have a flow rate regulating means for regulating the flow rate at the time of flowing out the contents, said flow regulating means, said spout, a flow rate regulating hole provided so as to narrow the opening diameter than the spout The refill container is characterized.

The invention according to claim 2 is a refill container used for replenishing a rigid container having a dispensing nozzle, having a refill container body and a plug, The spigot has a sleeve for fixing the refill container main body, a spout into which the nozzle for pouring the rigid container can be inserted, and a seal plate for sealing the refill container. has a flow rate regulating means for regulating the flow rate, the flow rate regulating means is a refill container you being a flow restricting seal provided on said refill container body.

The invention according to claim 6 is the refill container according to claim 5 , wherein the seal plate is provided inclined with respect to the central axis of the stopper.

Moreover, invention of Claim 7 has the cross-sectional shape in which the said spout fits the nozzle for extraction of the said rigid container, The clogging in any one of Claims 1-6 characterized by the above-mentioned. It is a replacement container.

The invention of claim 8 is a refill container according to any one of claims 1 to 7, characterized in that it has an over cap that covers the spout.

  The refill container according to the present invention has a refill container main body and a cap, and the plug inserts a sleeve for fixing the refill container main body and a nozzle for dispensing a rigid container to be used repeatedly. With a possible spout and a sealing plate that seals the refill container, the refill container is turned upside down and pushed into the spout to insert the rigid container pouring nozzle into the sealing plate automatically by the nozzle Once opened, the contents move to a rigid container. At this time, since the flow rate regulating means for regulating the flow rate when the contents are caused to flow out is provided, a large amount of contents are prevented from flowing out and overflowing at a time. Since the flow rate at this time is determined by the flow rate regulating means provided in the refill container, there is no difference between individuals performing the refill operation, and anyone can perform the refill operation safely.

  In addition, when the flow restricting means is a flow restricting hole provided in the cap so that the opening diameter is narrower than that of the spout, the conventional refill container body can be used as it is only by changing the plug. Can do. In addition, by providing the flow restricting hole in the sleeve portion of the plug, the contents can be discharged smoothly and the last drop can be discharged. Further, since the thickness of the sleeve is increased, it is possible to secure the strength of the sleeve when the refill container body is heat-sealed to the sleeve.

  Further, when the flow restricting means is a flow restricting seal provided on the refill container body, the conventional stopper and the conventional container body are used as they are, and a new flow restricting seal is simply applied to the container body. The object of the present invention can be achieved by extremely simple means.

  In addition, when the seal plate is a thin film that is easily broken by the dispensing nozzle tip of the rigid container, the shape of the nozzle tip is not selected, and from the standpoint of product safety in recent years, the nozzle tip is not sharpened. Although many products are flattened, they can also be applied to such rigid containers.

  Further, when the seal plate is formed integrally with a part of the plug and has a score for opening around it, the number of parts of the plug can be reduced, and the product can be supplied at low cost. it can. Furthermore, when the seal plate is provided to be inclined with respect to the central axis of the plug, when the refill container is inverted and the outflow nozzle of the rigid container is inserted into the spout, the rigid container Since the first nozzle is pressed against the position where the seal plate is the highest, the opening score always breaks from this one point, and the opening proceeds smoothly. Even for a rigid container having a nozzle shape with a flat tip as described above, opening by score breakage is performed smoothly.

Further, when the spout has a cross-sectional shape into which the dispensing nozzle of the rigid container is fitted, when the refilling container is inserted into the dispensing nozzle and inverted in the refilling operation. Anyone can safely carry out refilling work because it is stable and upside down.

  Moreover, when the plug for refill containers has an overcap that covers the spout, it is possible to prevent dust from entering the spout. If the overcap is fixed with a screw, the remaining use can be sealed and stored safely.

  Hereinafter, the refill container according to the present invention will be described in detail with reference to the drawings. 1 and 2 are cross-sectional explanatory views showing examples of embodiments of the refill container according to the present invention. The refill container according to the present invention has a refill container main body 4 and a spigot 1, and the spigot 1 is a sleeve 2 for fixing the refill container main body 4, and a rigid container for repeated use is poured out. It has the spout 3 which can insert the nozzle for use, and the sealing plate 5 which seals the refill container, and has a flow rate regulating means for regulating the flow rate when the contents are discharged. In the embodiment shown in FIGS. 1 and 2, a flow rate regulating hole 6 provided in the sleeve 2 of the plug 1 is provided as the flow rate regulating means. The flow rate restricting hole 6 is formed by narrowing the content flow path by making the cross-sectional area of the flow path smaller than the cross-sectional area of the spout 3. When the refill container main body 4 is a flexible packaging bag as shown in FIGS. 1 and 2, the container main body is deflated when the contents are discharged, so that the spout 3 of the spout 3 serving as the discharge port If the inner diameter is large, a large amount of contents may flow out at a time and overflow from the rigid container to be used repeatedly. The spout 3 of the plug used in the refill container according to the present invention has an inner diameter large enough to allow insertion of the nozzle of the rigid container to be used repeatedly, so that the flow restriction hole 6 has a large amount of contents at a time. Has the effect of preventing the spillage.

  The container body 4 of the refill container shown in FIGS. 1 and 2 is a so-called standing pouch having a bottom film at the bottom. In the refill container of FIG. 1, the plug 1 is provided at the top of the pouch. In the refill container of FIG. 2, the plug 1 is provided at the upper corner of the pouch. The plugs 1 used for these two refill containers are the same. As a fixing method of the stopper 1 and the container main body 4, it is general that the sleeve 2 of the stopper 1 is inserted into the opening of the container main body 4 and fixed by heat sealing. At this time, since the sleeve 2 is provided with the flow restriction hole 6, the sleeve 2 is thicker than the case where there is no flow restriction hole and the inner diameter is the same as that of the spout 3. Increased and heat fusion work becomes stable.

  FIG. 3 is a schematic cross-sectional view of the stopper used in the refill container shown in FIGS. 1 and 2, and shows the AA cross section of FIG. FIG. 4 is a schematic plan view of the spigot shown in FIG.

  A spigot 1 used for a refill container according to the present invention includes a sleeve 2 for fixing a refill container main body, a spout 3 into which a nozzle for dispensing a rigid container to be used repeatedly can be inserted, and a refill container sealed. This is a refill container stopper having a flow rate regulating means for regulating the flow rate when the contents flow out. In this embodiment, a flow restricting hole 6 is provided in the sleeve 2 as a flow restricting means. The inner diameter is narrowed so that the cross-sectional area of the flow restriction hole 6 is smaller than the cross-sectional area of the spout 3. The block of the sleeve 2 and the block of the spout 3 are manufactured as separate parts. After the seal plate 5 is attached to the block of the sleeve 2, the block of the spout 3 is screwed and fixed integrally. .

  Each block can be molded by a single molding by an injection molding method using a thermoplastic resin such as polyethylene resin, polypropylene resin, or polyester resin. The seal plate 5 needs to be made of a material that can be easily broken by the nozzle tip of a rigid container that is repeatedly used, which will be described later. Specifically, a composite material of an aluminum foil and a thermoplastic resin film is used.

  FIG. 4 is a schematic plan view of the spigot shown in FIG. The sleeve 2 has a triangular shape so that the soft packaging film of the refill container body can be easily fused. Although not shown in FIGS. 3 and 4, it is preferable to provide a plurality of ribs on the surface of the sleeve 2 that contacts the refill container body so as to facilitate thermal fusion.

FIG. 5 is a cross-sectional explanatory view showing the refilling operation from the spigot shown in FIG. 3 to the rigid container. In the figure, the refill container body is omitted. A nozzle cap 11 attached to the rigid container body 10 to be used repeatedly is provided with a nozzle 12 and a nozzle slit 14. In order to replenish the contents of the container, the refill container is inverted and inserted into the nozzle 12 so as to cover the spout 3 of the plug 1 of the refill container. At this time, the tip 13 of the nozzle abuts against the seal plate 5 and breaks the seal plate 5 so that the content in the refill container flows out as indicated by the arrow 7 indicating the content inflow direction and is rigid. Move to the container body 10. At this time, since the flow rate of the contents is regulated by the flow rate regulating hole 6 that is a flow rate regulating means provided in the sleeve 2, the contents do not overflow from the nozzle cap 11 of the rigid container.

  FIG. 6 is a schematic cross-sectional view showing another embodiment of the plug used in the refill container according to the present invention, and shows the BB cross section of FIG. FIG. 7 is a schematic plan view of the spigot shown in FIG. In this embodiment, the spigot 1 is composed of two blocks, a block formed by integrally forming a sleeve 2, a spout 3 and a seal plate 5, and a flow restriction block 15. The flow restriction block 15 is provided with a flow restriction hole 6 and a slit 9. In the plug 1, the seal plate 5 is provided to be inclined with respect to the central axis of the plug 1, and an opening score 8 is provided on the outer edge portion of the seal plate 5. As shown in FIG. 7, in this embodiment, the spout 3 of the spigot 1 has a cross-sectional shape into which the dispensing nozzle of the rigid container is fitted. When the plug 1 is inserted into the dispensing nozzle of the rigid container, it can be inserted exactly without wobbling, so it is easy to use. 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.

  Since the sealing plate 5 is inclined, when the refilling container is turned upside down and the rigid container pouring nozzle 12 is inserted into the spout 3, the sealing plate 5 is the most rigid pouring nozzle 12. Since it is first pressed against the raised position, the opening score 8 is always broken from this one point, and the opening starts smoothly, and the opening proceeds smoothly. For this reason, even if the tip 13 of the dispensing nozzle of the rigid container is not sharp and flat, opening is easily started.

  In the plug shown in FIG. 6, the flow regulating block 15 is present below the sleeve 2, that is, inside the refill container body 4, so that the portion of the plug 1 protruding outside the container is reduced. Has an effect. However, when the refilling container is turned upside down and the refilling operation is performed, the contents corresponding to the height of the flow restriction block 15 cannot be discharged. Therefore, in order to prevent this, a slit 9 is provided. And the last contents are discharged. In order to join the flow restricting block 15 to a block formed by integrally forming the sleeve 2, the spout 3 and the seal plate 5, an ultrasonic welding method is suitable.

  8 and 9 are schematic cross-sectional views showing other embodiments of the refill container according to the present invention. The refill container shown in FIGS. 8 and 9 is characterized in that the outflow amount is regulated by the flow regulation seal 17 provided in the refill container main body 4 without providing the flow regulating means in the stopper 1. The flow rate regulation seal 17 is provided with a seal portion similar to the seal on the periphery of the container in the vicinity of the spout of the container body, and there is no particular limitation on the shape and number of the seals. What is necessary is just to design suitably according to the viscosity of the contents. If even one flow rate regulation seal exists in the vicinity of the spout of the container body, the opening of the spout is greatly restricted, so that the effect of regulating the flow rate is great.

  Since the refill container shown in FIGS. 8 and 9 does not have a flow restricting means in the plug 1, the structure of the plug 1 is simplified. For example, the plug of the refill container shown in FIG. Since this corresponds to the upper half block of the spigot shown in FIG. 6, it can be molded as a single molded product.

FIG. 10 is a schematic cross-sectional view showing another embodiment of the stopper used in the refill container according to the present invention. In this embodiment, the overcap 1 is attached to the spout 3 of the spigot 1 shown in FIG.
6 is installed. When the plug 1 has the overcap 16 that covers the spout 3 as described above, dust can be prevented from entering the plug. Although not shown, when the overcap 16 is fixed with a screw, the remaining use can be sealed and stored safely.

  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. The refill container according to the present invention is used as a refill container for replenishing the contents of a rigid container that is used repeatedly, such as toiletries such as liquid detergents and softeners, and foods such as edible oil and instant coffee. be able to.
