  Hereinafter, embodiments of the present invention will be described 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 containing contents such as cream, an outer container 2 capable of storing the inner container 3, and the outer container 2. And an exterior cover 4.
The outer container 2 and the inner container 3 are each formed in a bottomed cylindrical shape, and are disposed such that the respective central axes are located on a common axis. Hereinafter, this common axis is referred to as an axis O, and the bottom wall portions 22 and 32 of the outer container 2 and the inner container 3 described later along the direction of the axis O are referred to as a lower side, and the opposite side is referred to as an upper side. Further, a direction orthogonal to the axis O is referred to as a radial direction, and a direction orbiting 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 on 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 or metal, and is formed by, for example, injection molding, blow molding, press molding, or the like.

  Above the peripheral wall portion 21, a neck portion 23 whose outer peripheral surface is reduced in diameter over the entire circumference is provided upright. The container body screw portion 24 is provided on the outer peripheral surface of the neck portion 23, and the container body screw portion 24 has an intermittent screw structure, so that a screw notch 25 is formed on the outer peripheral surface of the neck portion 23. The screw cutout 25 is a cutout in which the upper part of the neck tube 23 is cut out in a concave shape in a side view in order to insert a grip 35 of the inner container 3 described later. The threaded portion 25 extends downward from the upper end of the neck portion 23 along the direction of the axis O, and the outer peripheral portion of the peripheral wall portion 21 of the neck portion 23 is cut away except for the inner peripheral portion. . That is, the screw notch 25 has a concave shape opened radially outward in a plan view, and is formed along the inner peripheral surface of the peripheral wall 21 on the radial inside of the screw notch 25. Walls are provided. The screw cutouts 25 are provided at a pair of two places with the axis O interposed therebetween. On the upper side of the neck portion 23, a mouth portion 26 is formed in a form in which an inner peripheral surface of the neck portion 23 is extended upward. 27 are protruded.

  As shown in FIG. 3, the inner container 3 is a container that can be put in and taken out of the outer container 2, and is a refill container that can be appropriately replaced by a consumer. The outline configuration of the inner container 3 includes a substantially cylindrical peripheral wall 31 extending along the axis O, and a bottom wall 32 provided at a lower portion of the peripheral wall 31. The inner container 3 is a bottomed cylindrical inner container having an opening at an upper end, and is made of, for example, 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 mouthpiece 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 an end edge of the flange portion 33, and the grip portion 35 which is fitted into the above-mentioned threaded portion 25 when the inner container 3 is inserted inside the outer container 2 is provided on the annular peripheral wall portion 34. There is an extension hanging. The grip portion 35 is a substantially rectangular plate piece that is hung down along the axial direction from the lower end of the annular peripheral wall portion 34, and is provided at a pair of two locations with the axis O interposed therebetween, like the screw cut portion 25. . In this manner, by providing the grip portion 35 so as to fit into the screw notch 25, the grip portion 35 of the inner container 3 can be set to a size that can be easily gripped. On the outer surface of the grip portion 35, a slip stopper 36 having the same screw shape as 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 screw portion appears to be continuous when the container with the outer cover 4 removed is used. The anti-slip effect when grasped with a fingertip can be exhibited.
On the inner peripheral surface of the annular peripheral wall portion 34, an inner container side locking projection 37 is provided so as to protrude at a position facing the outer container side locking projection 27. The stop projection 37 gets over and fits undercut so as to prevent the inner container 3 from dropping out of the outer container 2 during use or the like.
The outer diameter of the peripheral wall 31 of the inner container 3 is slightly smaller than the inner diameter of the peripheral wall 21 of the outer container 2, and the inner container 3 is stored inside the outer container 2 with a gap. The outer diameter of the peripheral wall 31 of the inner container 3 and the inner diameter of the peripheral wall 21 of the outer container 2 may be the same.

  The exterior lid 4 is a top-end cylindrical overcap body that is screwed to the neck cylinder part 23 of the outer container 2, and includes a disc-shaped top wall part 41 disposed orthogonal to the axis O, And a cylindrical peripheral wall portion 42 hanging down from the edge of the wall portion 41. On the inner peripheral surface of the peripheral wall portion 42, an outer cover screw portion 43 that is screwed to the container body screw portion 24 of the outer container 2 and the screw-shaped slip stopper 36 of the inner container 3 is formed. A disk-shaped packing 5 is fitted inside the outer cover 4. The packing 5 is joined to the lower surface of the top wall portion 41 of the exterior lid 4. The inside of the inner container 3 is sealed.

Next, the operation of the double container 1 configured as described above will be described.
When the inner container 3 contained in the outer container 2 is replaced with a new inner container 3 when the contents in the inner container 3 are exhausted, first, the inner container 3 is attached to the outer container 2 shown in FIG. The external cover 4 is removed. When the outer cover 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 portion 35 is gripped with a fingertip, and the inner container 3 is pulled up. When the grip portion 35 is gripped, the slip stopper 36 has a screw shape, so that the fingertip can be prevented from slipping. Then, as shown in FIG. 2, since the slip stopper 36 provided on the grip 35 has the same screw shape as the container body screw 24, the screw seems 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 projection 27 and the inner container side locking projection 37 is released, and the inner container 3 is removed from the outer container 2 as shown in FIGS. Is removed. Thereafter, a new inner container 3 can be inserted into the outer container 2.

  As described above, in the present invention, the upper part of the inner container 3 (above the opening of the outer container 2) can be kept low, so that the overall design of the double container 1 is not affected. In addition, since the grip portion 35 is fitted into the threaded portion 25, it is possible to prevent the inner container 3 from rotating when the outer cover 4 is opened and closed and when the contents are used to be taken out from the inner container 3.

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

  As described above, the present invention can be easily sized so as to easily grip the grip portion when the inner container is removed, and the provision of the grip portion does not impair the sense of unity of the container design. Applications can be expanded over a wider area.
