  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes an outer container, which is formed on the mouth / neck portion 3 with the upper outer surface of the trunk portion 2 having a small outer diameter, and for the reasons described later, the upper outer surface of the mouth / neck portion 3 has a small outer diameter. Formed in the diameter portion 4. The upper inner surface of the mouth-and-neck portion 3 is formed in the large inner diameter portion 6 via the upward step portion 5, and the upper surface of the upward step portion 5 is a side-view wave-shaped uneven surface in which curved-shaped unevenness is alternately arranged, Alternatively, it is formed on a serrated uneven surface in which convex portions having a triangular shape in a side view and concave portions having an inverted triangle shape are alternately arranged.

On the inner surface of the upper portion of the large inner diameter portion 6, a first protrusion 8 is formed that constitutes a concave / convex retaining means 7. The first protrusion 8 may be formed by a plurality of protrusions arranged in the circumferential direction, or may be formed by a protrusion in the circumferential direction. In addition, the protrusion 9 spirally provided around the outer surface of the mouth-and-neck portion 3 is for screwing a cap (not shown).

  Reference numeral 10 denotes an auxiliary portion. An outer flange-like annular wall 12 is attached to the upper end of the auxiliary cylinder 11 fitted into the large inner diameter portion 6 via a gap, and the annular wall 12 is mounted on the upper end of the mouth neck portion 3. It is put. A second protrusion 13 is provided on the outer surface of the upper portion of the auxiliary cylinder 11 to form the unevenness retaining means 7. The second protrusion 13 is slidably engaged with the lower surface of the first protrusion 8. Yes.

When the upper surface of the upward stepped portion 5 is formed in a wavy uneven surface, the lower surface of the auxiliary cylinder 11 is formed in a wavy uneven surface. On the other hand, when the upper surface of the upward stepped portion 5 is formed in a serrated irregular surface, it is formed in a serrated irregular surface in the same manner. That is, the lower surface of the auxiliary cylinder 11 is configured to be complementary to the shape of the uneven surface on the upper surface of the upward step portion 5, and the lower surface of the auxiliary tube 11 and the upper surface of the upward step portion 5 in a normal use state except when the inner container is replaced. And can be engaged with each other. The uneven surface on the lower surface of the auxiliary cylinder 11 and the uneven surface on the upper surface of the upward stepped portion 5 of the outer container 1 constitute release means 15 that raises the auxiliary portion 10 and releases the retaining means 7.

  Reference numeral 20 denotes an inner container. As shown in FIG. 3, the peripheral wall 22 is suspended by fitting and bonding from the inner periphery of the outward flange 21 placed and bonded to the upper surface of the annular wall 12 of the auxiliary cylinder 11 to the inner surface of the auxiliary cylinder 11. Then, the bottom wall of the peripheral wall 22 is brought close to the bottom wall of the body portion 2 of the outer container 1. In FIG. 3, the inner container 20 and the auxiliary portion 10 are provided separately, but as shown in FIG. 4, they can be integrally formed.

  Further, the gripping cylinder 23 is suspended from the outer periphery of the outward flange 21, and a plurality of anti-slip protrusions 24 are formed on the outer surface of the gripping cylinder at predetermined intervals in the circumferential direction. When the inner container 20 is formed of metal, the lower end of the gripping cylinder 23 is bent inward along the lower surface of the annular wall 12 so that the hand does not touch the lower end edge of the gripping cylinder 23.

The reason why the upper outer surface of the mouth / neck portion 3 is formed in the small outer diameter portion 4 and the annular wall 12 is projected outward from the upper end of the mouth / neck portion 3 as shown in FIG. The space defined by the four outer surfaces and the lower surface of the annular wall 12 is to be a space 30 for inserting a finger to be applied to the lower surface of the annular wall 12 when the inner container 20 is replaced.

Therefore, the finger insertion space 30 can be omitted. In this case, as shown in FIGS. 3 and 4, the upper outer surface of the mouth-and-neck portion 3 does not have a small outer diameter, and an annular wall is provided. No. 12 places the entire lower surface on the upper end of the mouth and neck.

  In addition, although the synthetic resin material is used as the material of the outer container 1 and the auxiliary part 10, the material of the auxiliary part 10 is softer than the material of the outer container 1. Thus, when the auxiliary portion 10 is rotated, the outer container 1 is not damaged by being scraped by the auxiliary portion 10 or the like, and the auxiliary portion 10 can be inserted into the outer container 1. It becomes easy.

The material of the inner container 20 is a metal or a relatively hard synthetic resin material. In addition, when forming the auxiliary | assistant part 10 and the inner container 20 in a different body, although these mutually adhere | attach, insert molding is preferable as a means of adhesion | attachment.

Next, the operation will be described.
In normal use, a cap (not shown) may be unscrewed from the neck 3 and the contents may be taken out from the inner container 20.

  In order to replace the inner container 20 with a new inner container, the inner cylinder 20 may be rotated by holding the holding cylinder 23 of the inner container 20 and holding the outer container 1. Then, the auxiliary cylinder 11 is rotated together with the inner container 20, and the convex part on the lower surface of the auxiliary cylinder 11 that has meshed with the concave part on the upper step part 5 is separated from the concave part of the upward step part 5 and rides on the convex part. As a result, the auxiliary cylinder 11 is raised, the annular wall 12 is separated upward from the upper surface of the mouth-and-neck part 3, and the retaining means 7 is released by the second projecting part 13 getting over the first projecting part 8. The inner container 20 can be taken out from the outer container 1.

  In order to use the new inner container 20, it is only necessary to insert the inner container into the outer container 1, and then the second protrusion 13 gets over the first protrusion 8 and the lower surface of the auxiliary cylinder 11 faces the upward step 5. Engage with the top surface.

  In the present invention, when the contents are used up, only the inner container containing the contents is replaced, and the outer container can be used in the field of containers that can be used continuously.
