[0012] [Figure 1] 1 is a partially cross-sectional side view showing a discharge container according to an embodiment of the present invention. [Figure 2] FIG. 2 is a partially enlarged view of FIG. [Figure 3]2 is a partial cross-sectional side view showing a state in which a dispensing tool is being attached to a double container in the dispensing container shown in FIG. 1. FIG. DETAILED DESCRIPTION OF THE INVENTION

[0013] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0014] As shown in Figures 1 and 2, in one embodiment of the present invention, a discharge container 1 has an outer container body 2a and an inner container body 2b, and a double container 2 formed by connecting a cylindrical mouth portion 4, a body portion 5, and a bottom portion 6 in this order, and a discharge tool 3 attached to the mouth portion 4 to discharge the contents contained in the inner container body 2b. The discharge tool 3 is not particularly limited and may be a pump device or a discharge cap, but in this embodiment it is a pump device. The contents are not particularly limited and may be liquid, powder, or granules, but in this embodiment it is a liquid.

[0015] For ease of explanation, the axial direction along the central axis O of the mouth 4 will also be referred to as the up-down direction, one axial side along the central axis O of the mouth 4 from the bottom 6 to the mouth 4 will also be referred to as the upside, and the opposite axial side will be referred to as the downside, the radial direction perpendicular to the central axis O of the mouth 4 will simply be referred to as the radial direction, and the circumferential direction circumferentially around the central axis O of the mouth 4 will simply be referred to as the circumferential direction.

[0016] The double container 2 has an outside air inlet 7 in the mouth 4, which introduces outside air between the outer container body 2a and the inner container body 2b as the inner container body 2b contracts and deforms in response to the discharge of the contents. The outside air inlet 7 is configured as a through-hole that penetrates the outer container body 2a, but is not limited to this and may also be configured as, for example, a gap provided between the outer container body 2a and the inner container body 2b on the outer peripheral surface of the upper end of the mouth 4. The outside air inlet 7 is not limited to being provided in the mouth 4, but may also be provided in the body 5 or bottom 6.

[0017] The double container 2 may be configured without the outside air inlet 7. In this case, for example, the double container 2 may be configured so that outside air is introduced into the inside of the inner container body 2b as the contents are discharged.

[0018] The double container 2 has an outside air inlet 7 that introduces outside air between the outer container body 2a and the inner container body 2b due to the contraction and deformation of the inner container body 2b accompanying the discharge of the contents, thereby preventing the contents from being exposed to the outside air and maintaining the quality of the contents at a good level.

[0019] The double container 2 is formed by biaxially stretching and blow molding a preform assembly formed by stacking two cylindrical preforms with bottoms. The outer container body 2a (outer preform) is made of polyethylene terephthalate, and the inner container body 2b (inner preform) is made of polypropylene. However, the materials of the double container 2 are not limited to these. For example, the outer container body 2a and the inner container body 2b can each be made of polyester such as polyethylene terephthalate, or polyolefin such as polypropylene or polyethylene. The materials of the outer container body 2a and the inner container body 2b may be different from each other or the same.

[0020] The double container 2 is not limited to a configuration formed by biaxially stretching blow molding a preform assembly, but may be a configuration formed by, for example, biaxially stretching blow molding a bottomed tubular laminated preform having outer and inner layers that can be peeled from each other, or a configuration formed by extrusion blow molding a laminated parison having outer and inner layers that can be peeled from each other.The outer container body 2a and inner container body 2b may also be molded separately and then assembled.

[0021] The body 5 has a radial width that is wider than the mouth 4. In such a configuration, it is particularly difficult to separate the inner container from the outer container. However, the configuration of the body 5 is not limited to this, and it may have the same radial width as the mouth 4, for example.

[0022] When disposing of the dispensing container 1, it may be necessary to separate the outer container body 2a, the inner container body 2b, and the dispensing tool 3. For example, from the viewpoint of environmental consideration, there are cases where (i) the inner container body 2b, which is difficult to recycle because of the contents such as cosmetics attached thereto, is separated and the outer container body 2a is recycled, or (ii) the inner container body 2b and the outer container body 2a, which are made of different materials, are separated and recycled separately. The dispensing tool 3 may also be reused by replacing the double container 2.

[0023] Therefore, in order to make it easier to separate the outer container body 2a, the inner container body 2b, and the dispensing tool 3, the dispensing container 1 of this embodiment is configured as follows.

[0024] That is, the discharge container 1 is configured such that (a) the discharge tool 3 has an attachment member 3a that is detachably attached to the outer peripheral surface of the outer container body 2a at the mouth 4 via a first screw portion 8, and a main body 3b that detachably holds the attachment member 3a via a second screw portion 9, (b) the inner container body 2b has a protrusion 10 that protrudes radially outward from the outer container body 2a at the end (upper end) of the mouth 4 on one axial side, and (c) the attachment member 3a has a hook portion 11 that, when the attachment member 3a is removed from the mouth 4 on one axial side, gets caught on the protrusion 10 of the inner container body 2b, allowing the inner container body 2b to be removed together with the discharge tool 3 from the outer container body 2a on one axial side.

[0025] With this configuration, the discharger 3 can be removed by unscrewing the attachment member 3a from the outer container body 2a in one axial direction, and then by hooking the protrusion 10 with the hook 11, the inner container body 2b can also be removed in one axial direction from the outer container body 2a together with the discharger 3. Then, by unscrewing the attachment member 3a from the main body 3b and removing it, the discharger and the inner container body 2b can be separated. Therefore, the outer container body 2a, inner container body 2b, and discharger 3 can be easily separated.

[0026] However, the engagement structure for releasably attaching the attachment member 3a to the outer peripheral surface of the outer container body 2a at the mouth portion 4 is not particularly limited, and may be an engagement structure other than the first screw portion 8. Furthermore, the engagement structure for releasably holding the attachment member 3a to the main body portion 3b is not particularly limited, and may be an engagement structure other than the second screw portion 9.

[0027] The attachment member 3a has a cylindrical shape centered on the central axis O of the mouth 4. A hook portion 11 is provided above the first threaded portion 8, and a second threaded portion 9 is provided above the hook portion 11.

[0028] The main body 3b of the discharge tool 3 has an abutment part 12 that abuts downward against the inner container at the mouth 4 when the discharge tool 3 is attached to the double container 2. In this embodiment, the abutment part 12 is formed by a packing provided on the underside of the flange of the cylinder member.

[0029] The protrusion 10 extends continuously in the circumferential direction over the entire circumference. However, the protrusion 10 is not limited to this, and may, for example, be configured to extend intermittently in the circumferential direction. The hook 11 extends continuously in the circumferential direction over the entire circumference. However, the hook 11 is not limited to this, and may, for example, be configured to extend intermittently in the circumferential direction.

[0030] In addition, in order to facilitate attachment of the discharge tool 3 to the double container 2, the discharge container 1 is configured so that the hook portion 11 of the attachment member 3a is a protrusion that protrudes radially inward at an angle to one side in the axial direction, and is capable of climbing over the protrusion 10 of the inner container body 2b to the other side in the axial direction by elastically deforming.

[0031] According to this configuration, with the outer container body 2a and the inner container body 2b combined, the hook portion 11 of the discharge device 3 is abutted downward against the protruding portion 10 as shown in Fig. 3, and elastically deformed to overcome the protruding portion 10, thereby easily attaching the discharge device 3 to the double container 2. On the other hand, when removing the discharge device 3 from the outer container body 2a, the hook portion 11 is prevented from elastically deforming to overcome the protruding portion 10 upward, so the inner container body 2b can be easily removed together with the discharge device 3. However, the configuration of the discharge device 3 is not limited to this.

[0032] The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0033] Therefore, the dispensing container 1 of the above-described embodiment can be modified as long as it is a dispensing container 1 that has an outer container body 2a and an inner container body 2b, and a double container 2 formed by connecting a cylindrical mouth portion 4, a body portion 5, and a bottom portion 6 in this order, and a discharge tool 3 that is attached to the mouth portion 4 and discharges the contents contained in the inner container body 2b, and the discharge tool 3 has an attachment member 3a that is detachably attached to the outer peripheral surface of the outer container body 2a at the mouth portion 4, and a main body portion 3b that detachably holds the attachment member 3a, and the inner container body 2b has a protrusion 10 that protrudes radially outward from the outer container body 2a at the end of the mouth 4 on one axial side from the bottom 6 toward the mouth 4 along the central axis O of the mouth 4, and the attachment member 3a has a hook portion 11 that hooks onto the protrusion 10 of the inner container body 2b when the attachment member 3a is removed from the mouth 4 on one axial side, and removes the inner container body 2b together with the discharge tool 3 from the outer container body 2a on one axial side.
