  Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, a double container 1 according to the present invention is attached to an inner container 3 that contains contents such as cream, an outer container 2 that can contain the inner container 3, and an outer container 2. And an exterior lid 4.
The outer container 2 and the inner container 3 are each formed in a bottomed cylindrical shape, and are arranged so that the central axes are located on a common axis. Hereinafter, this common axis will be referred to as an axis O, the bottom walls 22 and 32 of the outer container 2 and the inner container 3 described later along the axis O direction will be referred to as the lower side, and the opposite side will be referred to as the upper side. A direction perpendicular to the axis O is referred to as a radial direction, and a direction around the axis O is referred to as a circumferential direction.

  The outer container 2 is a bottomed cylindrical outer container having an open upper end, and is provided in a substantially cylindrical peripheral wall portion 21 extending along the axis O and a lower portion of the peripheral wall portion 21. And a bottom wall portion 22. The outer container 2 is made of, for example, a synthetic resin such as polyester, polystyrene, or polyolefin, glass, metal, or the like, and is molded by, for example, injection molding, blow molding, press molding, or the like.

  On the upper side of the peripheral wall portion 21, a neck tube portion 23 having an outer peripheral surface whose diameter is reduced over the entire circumference is erected. The container body screw portion 24 is provided on the outer peripheral surface of the neck tube portion 23, and the screw portion 25 is formed on the outer peripheral surface of the neck tube portion 23 by making the container body screw portion 24 have an intermittent screw structure. The screw notch 25 is a notch obtained by notching the upper part of the neck tube 23 in a concave shape in a side view in order to insert a grip 35 of the inner container 3 to be described later. The screw notch 25 extends downward along the direction of the axis O from the upper end of the neck tube 23, and the outer peripheral portion of the peripheral wall 21 of the neck tube 23 is cut away while leaving the inner periphery. . That is, the screw notch 25 has a concave shape opened toward the radially outer side in plan view, and is formed along the inner peripheral surface of the peripheral wall 21 on the radially inner side of the screw notch 25. A wall portion is disposed. The screw notches 25 are disposed at a pair of two locations with the axis O interposed therebetween. A mouth tube portion 26 is formed on the upper side of the neck tube portion 23 in a form in which the inner peripheral surface of the neck tube portion 23 extends upward, and an outer container side latching protrusion is formed on the outer peripheral surface of the mouth tube portion 26. 27 is protrudingly provided.

  As shown in FIG. 3, the inner container 3 is a container that can be inserted into and removed from the outer container 2, and is a refill container that can be appropriately replaced by a consumer. As a schematic configuration of the inner container 3, a substantially cylindrical peripheral wall portion 31 extending along the axis O and a bottom wall portion 32 provided at a lower portion of the peripheral wall portion 31 are provided. The inner container 3 is a bottomed cylindrical interior container having an opening at the upper end, and is made of a synthetic resin such as polyester, polystyrene, or polyolefin, and is formed by, for example, injection molding or blow molding.

At the upper end of the peripheral wall portion 31, an outer flange-shaped flange portion 33 that is placed on the upper end surface of the mouth tube portion 26 of the outer container 2 and sets the assembly limit of the inner container 3 is formed. An annular peripheral wall portion 34 is suspended from the edge of the flange portion 33, and a grip portion 35 fitted into the above-described screw notch portion 25 when the inner container 3 is inserted into the outer container 2. Is extended. The grip portion 35 is a substantially rectangular plate piece that hangs down in the axial direction from the lower end of the annular peripheral wall portion 34, and is disposed in a pair of two locations with the axis O in between, as in the screw notch portion 25. . Thus, by providing the grip portion 35 so as to fit into the screw notch portion 25, the size of the grip portion 35 of the inner container 3 can be set to be easy to grip. On the outer surface of the grip portion 35, a screw stopper 36 having the same screw shape as that of the container body screw portion 24 is provided so as to be continuous with the container body screw portion 24. By making the shape of the slip stopper 36 into a screw shape, the grip portion 35 can be held while maintaining a sense of unity of the external design by making the screw portion appear to be continuous when using the container with the outer lid 4 removed. The anti-slip effect when grasped with a fingertip can be exhibited.

Remove the outer lid 4. When the outer lid 4 is removed, the packing 5 is also removed.

  Next, in order to remove the inner container 3 from the outer container 2, the grip part 35 is grasped with a fingertip, and the inner container 3 is pulled upward. When the grip portion 35 is gripped, the anti-slip effect of the fingertip can be exhibited because the slip stopper 36 has a screw shape. As shown in FIG. 2, the slip stopper 36 provided on the grip portion 35 has the same screw shape as the container body screw portion 24, so that the screw portion appears to be continuous, so that the appearance design is improved. You can keep feeling.

  When the inner container 3 is pulled upward, the undercut fitting between the outer container side locking protrusion 27 and the inner container side locking protrusion 37 is released, and the inner container 3 is removed from the outer container 2 as shown in FIGS. 3 and 4. Is removed. Thereafter, a new inner container 3 can be inserted into the outer container 2.

  Thus, in this invention, since the upper part (above the opening part of the outer container 2) of the inner container 3 can be restrained low, the whole design of the double container 1 is not affected. In addition, by fitting the grip 35 into the screw notch 25, it is possible to prevent the inner container 3 from rotating when the outer lid 4 is opened and closed and when the contents are taken out from the inner container 3.

As described above, the configuration and the operation effect of the present invention have been described along the examples. However, the embodiment of the present invention is not limited to the above embodiment.
For example, in the above embodiment, the inner container 3 is made of synthetic resin, but may be a thin metal container formed by, for example, press molding or the like.

  As described above, the present invention can easily grip the gripping portion when the inner container is removed, and does not impair the unity of the container design even if the gripping portion is provided. Applications can be expanded in a wider area.
