However, in this hand-held refillable container, since the container sealing member is disposed between the fixing member and the coupling member, the fixing member and the coupling member must be combined after being manufactured as separate parts, which increases the number of parts. In addition, there is a problem that the manufacturing process increases.
Further, since this refill container is screwed into the opening of the container for repeated use and connected, it is necessary to turn the screw during the refill operation, which is not always convenient for consumers.

  The present invention pays attention to the fact that a container for repeated use generally comprises a pouring nozzle and a peripheral wall provided around the pouring nozzle via a flow passage for returning the contents. It is an object of the present invention to provide a refill container that can be refilled easily and quickly and can be replenished without spilling the contents by using the flow path for returning goods and the peripheral wall.

That is, the invention according to claim 1 replenishes contents to a repetitively used container comprising a pouring nozzle and a peripheral wall provided around the pouring nozzle via a flow passage for returning contents. In the refill container to
A refill container main body that contains the contents, a cylindrical filling portion that is disposed in a part of the refill container main body and through which the extraction nozzle is inserted, seals the cylindrical filling portion, and a tip of the extraction nozzle And a sealing member that is broken by, and an overcap that covers the cylindrical filling portion,
The overcap is composed of a cylindrical side wall and a top plate removable from the side wall, and the height (A) of the side wall and the height (B) of the cylindrical filling portion are A> It is a refill container characterized by satisfying the relationship B.

  According to this invention, when refilling the contents, first, the top plate, which is a constituent member of the overcap of the refill container, is removed, then the refill container is inverted, and the refill container is repeatedly placed on the sealing member of the refill container. The refill container is opened by inserting the tip of the outlet nozzle and breaking the sealing member. Then, the contents in the refill container flow out sequentially through the cylindrical filling portion and the side wall of the overcap.

  Here, the height (A) of the side wall of the overcap and the height (B) of the cylindrical filling portion satisfy the relationship of A> B. That is, the sealing member is disposed so as to be surrounded by the side wall of the overcap. Even when the contents are scattered radially when the sealing member is broken, the side wall of the overcap can prevent the contents from scattering as a protective wall. Further, the side wall of the overcap serves as a guide member for guiding the dispensing nozzle to the sealing member.

In the invention according to claim 2, the height (A) of the side wall, the height (B) of the cylindrical filling portion, the height (C) of the dispensing nozzle, and the height (D) of the peripheral wall are:
The refill container according to claim 1, wherein a relationship of C> (A−B) ≧ (C−D) is satisfied.

Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view of a main part of a refill container 1 according to an embodiment of the present invention. However, the right side of the dot-dash line in the center shows a state where the top plate 11 of the overcap 13 is covered, and the left side shows a state where the top plate 11 of the overcap 13 is removed and the sealing member 14 is exposed.

In this example, a plastic blow bottle is used as the refill container body 16. The blow bottle material may be polyethylene terephthalate, polyethylene, polypropylene or the like. Then, the neck portion is used as a cylindrical filling portion 15, and a sealing member 14 is adhered and closed at the opening portion. The blow bottle 16 contains contents (not shown). The contents are preferably liquid or powdery, for example, toiletries such as liquid detergents and softeners, edible oils, and instant coffee.
Moreover, as the refill container body 7, a soft packaging bag, a paper container, etc. other than a plastic blow bottle can be used.

The overcap 13 includes a cylindrical side wall 12 and a top plate 11 that can be removed from the side wall 12. In FIG. 1, a male screw is provided on the outer periphery of the cylindrical filling portion 15 and is screwed with a female screw provided on the inner periphery of the side wall 12 of the overcap 13. The joining method with 13 may be a screw type or a fitting type, and is not limited to this.
The overcap 13 is for preventing impurities from being mixed and preventing the sealing member from being broken by being exposed.

  The top plate 11 is a member that can be removed from the cylindrical side wall 12, and may be any member that closes the opening at the top of the side wall 12. For example, as shown in FIG. 1, a fitting-type coupling member can be used, but the present invention is not limited to this, and may be a screw type. A shrink film may be used as the top plate 11.

  The sealing member 14 seals the cylindrical filling portion 15 and is made of a fragile material so as to be easily broken by the dispensing nozzle of the rigid container. For 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. Such a sealing member can be bonded to the cylindrical filling portion 6 using an adhesive. It is also possible to bond by heat sealing.

  Next, FIG. 2 shows the longitudinal cross-sectional view of a repeated use container.

  The repeated use container 2 shown in FIG. 2 consists of the plastic blow bottle 21, and the nozzle cap 22 is attached to the opening. As for the nozzle cap 22, the extraction | pouring nozzle 221 has stood up in the center part. In the nozzle cap 22, the contents return flow path 222 surrounds the periphery of the pouring nozzle 221 erected at the center, and the peripheral wall 223 surrounds the periphery thereof. In this way, the content returning flow path 222 sandwiched between the pouring nozzle 221 and the peripheral wall 223 communicates with the slit downstream. In addition, when the content is poured out by tilting the blow bottle 21, the height of the peripheral wall 223 is configured to be lower than the pouring nozzle 221 so that the pouring operation is not hindered.

  Although not shown, the blow bottle 21 includes a cap that covers the nozzle cap 22. This prevents impurities from entering the blow bottle 21 from the outside. Moreover, it may have a function to prevent the contents from spilling when it falls. Moreover, generally, it is normally playing the role of the measuring cup which measures the quantity by pouring from the blow bottle 21 into this cap.

  In refilling the contents, first, the dispensing nozzle 221 of the reusable container 2 is inserted into the side wall 12 from which the top plate has been removed (FIG. 3), and then the tip of the dispensing nozzle 221 is moved in the refill container insertion direction 42. It pushes in and inserts and breaks through the sealing member 14 (FIG. 4). The content flows out from the broken sealing member 41, but the content does not flow out only in the direction of gravity and may scatter in an unexpected direction. When the height (A) of the side wall 12 of the overcap 13 and the height (B) of the cylindrical filling portion 15 are A ≦ B, the contents scattered in an unexpected direction are repeatedly put out of the peripheral wall 223 of the container for use. It may spill.

  In the present invention, the height (A) of the side wall 12 of the overcap 13 and the height (B) of the cylindrical filling portion 15 satisfy the relationship of A> B. That is, the sealing member 14 is disposed so as to be surrounded by the side wall 12 of the overcap 13. Thereby, even if the contents are scattered in an unexpected direction, the side wall 12 of the overcap 13 can prevent the contents from scattering as a protective wall. Further, the side wall 12 of the overcap 13 serves as a guide member for guiding the dispensing nozzle 221 to the sealing member 14.

  Here, the height (A) of the side wall 12 refers to the distance from the lower end to the upper end of the side wall 12, and the height (B) of the cylindrical filling portion 15 refers to the cylindrical filling portion 15 from the lower end of the side wall 12. The distance to the upper end (position where the sealing member 14 is disposed).

  In general, the pouring nozzle 221 of the repetitively used container 2 protrudes from the peripheral wall 223 disposed in the periphery thereof, that is, the height (C) of the pouring nozzle 221 and the height of the peripheral wall 223. (D) is formed so as to satisfy the relationship of C> D.

When refilling such a repeated use container 2, the height (A) of the side wall 12, the height (B) of the cylindrical filling portion 15, the height (C) of the pouring nozzle 221, and the peripheral wall 223. Height (D) is
It is preferable that the relationship of C> (A−B) ≧ (C−D) is satisfied.
