Description

  The present invention relates to an extraction adapter for a refill container used for containing the same contents as those contained in a main body container of a product and refilling the contents when the contents in the main body container are exhausted.

  For example, liquid, gel, powder or granular products such as detergents and cosmetics are sold in containers such as injection-molded containers made of resin and bottles. However, the manufacturing cost of containers has increased due to the recent rise in raw materials due to the rise in oil prices, and this has been reflected in the selling price, which has also affected consumers. Further, since the container itself is large and cannot be deformed, it is bulky, and it is difficult to clean up when it is taken out or processed as garbage.

  Therefore, the seller of the product provides, as a product, a product that contains the same contents as the contents in the main body container in the refill container separately from the main body container that contains the product. When a person runs out of contents in the main body container, the contents of the refill container are refilled into the main body container and replenished.

  In addition, as such a refill container, a flexible package such as a pouch container that is a self-standing bag having a flexible sheet such as a resin sheet has become common. Such a flexible package is advantageous in that the manufacturing cost of the container itself is low and can be discarded in a folded state when it is used and discarded. However, on the other hand, there is a problem that the refilling operation cannot be performed smoothly or the product is spilled and wasted.

  For example, a flexible package for shampoo is designed to cut the upper corner of the package diagonally to form an extraction port, and pour the shampoo into the main body container from this extraction port. When it becomes necessary to refill, it is difficult to cut off the corners for sliding with shampoo. Moreover, even if it is performed using a scissors, there is a risk of slipping and injuring hands and fingers, which is dangerous. When pouring the flexible package upside down, the extraction opening of the flexible package is easily displaced from the opening of the container body, and it takes a lot of trouble to pour while matching. And even if you pour carefully, it is often spilled and wasted in large quantities. Moreover, it is difficult to seal the extraction port once cut and formed, and if it is left as it is, problems such as dust entering inside and deterioration in quality occur.

  The present invention has been made in view of the above points, and can solve the above-mentioned problems in the refilling operation of the conventional refilling container by attaching it to the extraction port of the refilling container such as a flexible package. It is intended to provide an extraction adapter for a refill container that can be used.

  Thus, the gist of the present invention is to attach to the extraction port of the refill container, a cylindrical main body formed with a male screw on the outer periphery of the top, and a base opening connected to the inner surface of the cylindrical main body, A cylindrical body is attached to the front end opening, a male screw is formed on the outer periphery of the cylindrical body, and a flexible guide hose having a required length is housed in the tubular body so as to be freely drawn out. A female thread that is screwed with a male thread on the outer periphery of the top of the cylindrical main body is formed, and a cylindrical body is integrally suspended at the center of the lower surface, and attached to the inner end of the cylindrical body at the distal end opening of the flexible guide hose. An extraction adapter for a refill container comprising a cap body formed with a female screw threadedly engaged with a male screw on the outer periphery of a cylindrical body.

  Moreover, in the said structure, you may make it provide the appropriate means to block | close the inside of a cylindrical main body temporarily. In such a case, the cap body attached to the cylindrical main body seals the opening of the cylindrical main body and the tip opening of the flexible guide hose and closes the inside of the cylindrical main body. Sealing can reliably prevent the outflow of the contents due to vibration during transportation and impact due to overturning. In addition, by closing at a position below the flexible guide hose in the cylindrical main body, it is possible to prevent the contents from adhering to the flexible guide hose until at least the first use. You can avoid filthy feelings.

  Further, as an example of means for temporarily closing the inside of the cylindrical main body, a plate having a through hole at the center is provided at a position below the flexible guide hose on the inner surface of the cylindrical main body. An example is provided in which an adhesive is applied to the upper surface, and the flexible guide hose is releasably bonded to the plate so that a part of the flexible guide hose blocks the through hole of the plate. be able to.

  Further, as another example of the means for temporarily closing the inside of the cylindrical main body, a cap shape is formed, an internal thread is formed on the inner surface of the outer vertical wall, and a protrusion is provided on the upper surface. A cylindrical body having a male thread formed on the outer periphery of the top vertical outer wall of the plug body, which is attached to the extraction port of the refill container, and a male thread threadedly engaged with the female thread on the inner surface of the outer vertical wall of the plug body. Formed on the inner surface of the lower opening of the main body is a male screw on the outer periphery of the projecting portion of the plug body or a female screw that engages with a male screw on the outer periphery of the top portion of the cylindrical body, and the cylindrical main body is refilled with the plug body interposed therebetween. And a means configured to be connected to the cylindrical body attached to the extraction port of the container.

  The present invention is configured as described above, and is attached to an extraction port of a refill container such as a flexible package by an appropriate means such as adhesion. And, when using, first remove the cap body and pull out the flexible guide hose from the cylindrical main body, then open the distal end opening of the flexible guide hose by removing the cap body, and open the distal end of the flexible guide hose. The contents are refilled into the opening of the container body, and in this state, the refill container is turned upside down and the contents are poured.

  As described above, the present invention can be easily opened by simply twisting the screwed cap body by hand. In order to form an extraction port as in the prior art, the present invention can be excised by hand or using a scissors. There is no need. Moreover, since there is no need to use a heel, there is no risk of hurting hands and fingers. In addition, since the injection is performed with the tip of the flexible guide hose inserted into the opening of the container main body for refilling the contents, the troublesome work of matching the extraction port of the refilling container with the opening of the container main body is eliminated. In addition, the entire amount can be reliably filled without spilling. Therefore, the refilling operation can be performed easily and smoothly. In addition, since the tip opening of the flexible guide hose can be resealed after being filled once, dust can be prevented from entering the inside and quality can be prevented from deteriorating. In addition, since it is not necessary to use up all at once, the refill container can be enlarged. Moreover, since the cylindrical body which formed the external thread in the outer periphery is attached to the front-end | tip opening of a flexible guide hose, if the internal thread screwed together with this is formed in the opening of a main body container, the front-end | tip opening of a flexible guide hose and a main body Connection with the opening of the container can be achieved, and the refilling operation can be performed more reliably and smoothly.

  In addition, since the flexible guide hose is housed in the cylindrical main body until it is used, it does not get in the way during transportation, storage, product display, etc., and contamination on the outer surface is prevented.

  In addition, when an appropriate means for temporarily closing the inside of the cylindrical body is provided, the opening of the cylindrical body and the distal end opening of the flexible guide hose are sealed with a cap body attached to the cylindrical body. At the same time, the cylindrical main body is also closed, and the double sealing can surely prevent the outflow of the contents due to vibration during transportation and impact due to overturning. In addition, by closing at a position below the flexible guide hose in the cylindrical main body, it is possible to prevent the contents from adhering to the flexible guide hose until at least the first use. It is something that can prevent a filthy feeling.
