Detailed Description

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

(first embodiment)

First, as a first embodiment of the present invention, for example, a capped container 100A including a capping unit 1A shown in fig. 1 to 6 will be described.

Fig. 1 is a perspective view showing an external appearance of the capped container 100A including the cap unit 1A. Fig. 2 is a vertical cross-sectional view showing the structure of the capped container 100A including the capping unit 1A. Fig. 3 is a perspective view showing a state in which the inner plug 10 is detached from the outer cap 9 provided in the cap unit 1A. Fig. 4 is a perspective view of the outer lid 9 of the cap unit 1A from below. Fig. 5 is a perspective view of the inner plug 10 of the cap unit 1A from below. Fig. 6 is a perspective view of the inner plug 10 of the cap unit 1A from a lower side.

As shown in fig. 1 and 2, the capped container 100A of the present embodiment includes a container body 2 having an upper opening, and a cap unit 1A detachably attached to the container body 2, and is a beverage container capable of insulating or cooling a beverage (contents) stored in the container body 2.

Specifically, the container body 2 includes an outer container 3 and an inner container 4 made of metal, such as stainless steel. The container body 2 has a vacuum heat insulating structure in which the vicinity of the open ends of the inner container 4 is joined to each other in a state in which the inner container 4 having one open end is housed inside the outer container 3 having one open end, and a vacuum heat insulating layer 5 is provided between the outer container 3 and the inner container 4.

The vacuum heat insulating layer 5 can be formed by sealing an exhaust hole provided in the center of the bottom surface of the outer container 3 with solder in a chamber that is depressurized (evacuated) to a high vacuum, for example.

The container body 2 has such a vacuum heat insulation structure, and thus can have functions such as heat preservation and cold preservation. Further, by providing such a vacuum heat insulation structure in the container body 2, tension is always applied to the outer container 3 and the inner container 4 by a difference between the inner pressure (vacuum pressure) and the outer pressure (atmospheric pressure), and the mechanical strength of the outer container 3 and the inner container 4 increases. Accordingly, even when the thicknesses of the outer container 3 and the inner container 4 are made thinner, the rigidity of the container body 2 can be improved, and the weight of the container body 2 can be reduced.

The container body 2 has: a substantially circular bottom surface portion 2b; the main body 2c is substantially cylindrical and rises from the outer periphery of the bottom surface 2b; and a neck portion 2d that is substantially cylindrical and is erected from the upper side of the main body portion 2 c. The upper end of the neck portion 2d is opened in a circular shape, and serves as an upper opening 2a of the container body 2.

A female screw portion 6 is provided on the inner peripheral surface of the mouth-neck portion 2 d. Further, an annular projection 7 is provided below the female screw portion 6 so as to protrude from the inner peripheral surface of the inner container 4 over the entire periphery.

The capped container 100A of the present embodiment has a generally cylindrical external shape as a whole, but the external shape of the capped container 100A is not particularly limited, and may be appropriately changed according to the size, external design, and the like. The outer peripheral surface of the container body 2 (outer container 3) may be coated or printed.

The cap unit 1A of the present embodiment constitutes a lid body for opening and closing the upper opening 2a of the container body 2. Specifically, as shown in fig. 2 to 6, the cap unit 1A includes a cap body 8 that closes the upper opening 2a of the container body 2 in a state in which the upper opening 2a of the container body 2 is fitted into the inside of the container body 2, and has a structure in which the cap body 8 is attached to the container body 2 by screwing.

The cap body 8 has: an outer cover 9 surrounding an upper portion of the container body 2; an inner plug 10 fitted into the container body 2 from the upper opening 2 a; and a detachable mechanism 11A for detachably attaching the inner plug 10 to the outer lid 9.

As shown in fig. 2 and 4, the cover 9 is made of, for example, a heat-resistant resin, and includes: the peripheral wall 9a is formed in a substantially cylindrical shape so as to be continuous in appearance with the body 2c of the container body 2; an upper wall 9b that closes the upper outer peripheral side of the peripheral wall 9a over the entire periphery; and an opening 9c that opens at the center of the upper wall 9b in a substantially circular shape.

As shown in fig. 2, 5 and 6, the inner plug 10 is made of, for example, a heat-resistant resin, and includes: a bottom wall portion 10a of a substantially circular shape; the peripheral wall portion 10b is substantially cylindrical and rises from the periphery of the bottom wall portion 10a; a top wall portion 10c closing an upper portion of the peripheral wall portion 10 b; and a flange portion 10d in which a top wall portion 10c protrudes in the diameter-expanding direction from a peripheral wall portion 10 b.

The inner plug 10 has a bottom-side plug member 12 having a substantially cylindrical shape and forming a bottom wall portion 10a and a peripheral wall portion 10b, and a top-side plug member 13 having a substantially circular shape and forming a top wall portion 10c and a flange portion 10d, and is configured such that the bottom-side plug member 12 is integrally attached to the lower surface of the top-side plug member 13 by welding or the like. The interior of the inner plug 10 is not limited to air serving as a heat insulating layer, and may be configured to have a heat insulating material S.

Further, a male screw portion 14 is provided on the outer peripheral surface of the peripheral wall portion 10b (the inner plug 10). In the capped container 100A, the cap body 8 (cap unit 1A) is detachably attached to the container body 2 by screwing the male screw portion 14 and the female screw portion 6. The female screw portion 6 and the male screw portion 14 are formed of two threads having mutually complementary shapes. In the case of using two threads, the cap body 8 (cap unit 1A) can be attached to and detached from the container body 2 with less rotation operation (about 180 ° in the present embodiment).

A water stop seal 15 is integrally attached to the outer peripheral portion of the lower end side of the inner plug 10. The water-stop seal 15 is an annular seal member for sealing the space between the protrusion 7 of the container body 2 and the inner plug 10, and is made of, for example, a heat-resistant rubber such as silicone rubber or an elastic member such as an elastomer. The water-stop seal 15 is integrally formed with the inner plug 10 (cap body 8) by insert molding, which will be described later.

The inner plug 10 has: a first concave portion 10e having a shape corresponding to a first convex portion 15a protruding inward from an upper end portion of the inner peripheral side of the water-stop seal 15; and a second concave portion 10f having a shape corresponding to a second convex portion 15b protruding upward from the lower end portion of the inner peripheral side of the water stop seal 15. The plug 10 has a third protrusion 10g, and the third protrusion 10g is located between the first protrusion 15a and the second protrusion 15b of the water-stop seal 15 and has a shape corresponding to the third recess 15c of the water-stop seal 15 formed between the first recess 10e and the second recess 10f of the plug 10.

In the cap unit 1A of the present embodiment, the first convex portion 15a of the water-stop seal 15 protruding inward is formed integrally with the first concave portion 10e of the inner plug 10, and the second convex portion 15b of the water-stop seal 15 protruding upward is formed integrally with the second concave portion 10f of the inner plug 10. The third concave portion 15c of the water-stop seal 15 and the third convex portion 10g of the inner plug 10 are integrally formed, so that the adhesion strength of the water-stop seal 15 integrally attached to the inner plug 10 (cap main body 8) can be improved by the respective anchoring effects.

The lower surface of the inner plug 10 has a shape in which the bottom wall portion 10a is recessed upward, and is coplanar with the lower surface of the water stop seal 15. Thus, the water-stop seal 15 is hardly peeled off from the inner plug 10 at the boundary between the lower surface of the inner plug 10 and the lower surface of the water-stop seal 15. In addition, since there is no gap in the vicinity of the boundary, water droplets are less likely to accumulate and are sanitary.

Further, two elastic flange portions 15d are provided on the outer peripheral surface of the water stop seal 15 so as to protrude in the diameter-expanding direction. When the cap main body 8 (cap unit 1A) is attached to the container main body 2, the elastic flange portion 15d of the water-stop seal 15 elastically deforms, and is brought into close contact with the projection portion 7 of the container main body 2 over the entire circumference. This can seal (stop) the space between the protruding portion 7 (container body 2) and the inner plug 10 (cap body 8).

The shape of the water-stop seal 15 is not limited to the above, and for example, the number of the elastic flange portions 15d is not limited to two and may be one or more.

The water-stop seal 15 is not necessarily limited to the structure provided with the elastic flange portion 15d, and the shape thereof and the like may be appropriately changed. For example, an elastic flange portion having a shape that is bent downward from the upper end of the outer peripheral surface of the water stop seal 15 may be provided.

As shown in fig. 2 to 6, the attaching/detaching mechanism 11A includes: a locking portion 16 provided on one of the outer lid 9 and the inner plug 10 (in the present embodiment, the outer lid 9); and a locked portion 17 provided on the other side (in the present embodiment, the inner plug 10).

The locking portion 16 has a plurality of (two in the present embodiment) locking projections 16a provided around the opening 9c of the outer lid 9. The two locking projections 16a are provided so as to protrude inward in the horizontal direction from positions opposed to each other across the opening 9c of the outer lid 9.

On the other hand, the engaged portion 17 has a plurality of (two in the present embodiment) engaging concave portions 17a provided inside the lower surface of the flange portion 10d that is the outer peripheral portion of the inner plug 10. The two locking recesses 17a are provided at opposite positions on the back surface side of the inner plug 10 inside the lower surface of the flange portion 10d of the inner plug 10. Each locking recess 17a is located between a pair of rib walls 17b protruding outward from the inner side of the lower surface of the flange portion 10d of the inner plug 10 and the flange portion 10d, and is provided so as to recess a part of the upper plug member 13.

In the attaching/detaching mechanism 11A, the inner plug 10 is inserted from above into the opening 9c of the outer lid 9, and the locking convex portions 16a pass over the lower surface side of the locking concave portions 17a by elastic deformation (deflection) of the outer lid 9. At this time, the locking convex portions 16a are locked to the locking concave portions 17a in a state where the flange portion 10d of the inner plug 10 is brought into contact with the periphery of the opening portion 9c of the outer cap 9, and the locking portions 16 are locked to the locked portions 17. Thereby, the inner plug 10 can be attached to the outer cap 9.

That is, the locking of the locked portion 17 and the locking portion 16 in the attaching/detaching mechanism 11A is based on elastic deformation (deflection) of the outer cap 9, and the outer cap 9 and the inner cap 10 are integrated by the locking of the locked portion 17 provided in the inner cap 10 and the locking portion 16 provided in the outer cap 9.

In the attachment/detachment mechanism 11A, each locking concave portion 17a is located between the pair of rib walls 17b, and each locking convex portion 16a is locked to each locking concave portion 17a, thereby restricting movement of each locking convex portion 16a in the left-right direction (rotational direction).

Thus, when the cap body 8 (cap unit 1A) is rotated about the central axis by gripping the outer cap 9, the respective locking projections 16a come into contact with the pair of rib walls 17b from the inner wall surface side, and thus the outer cap 9 and the inner plug 10 are integrally rotated. Therefore, the cap body 8 can be attached to the container body 2 by rotating the outer lid 9 by holding it.

In addition, when the cap body 8 (cap unit 1A) is removed from the container body 2, only the rotation direction is reversed, as in the case of mounting. That is, the outer lid 9 of the cap body 8 is gripped and rotated in the opposite direction to the direction of the container body 2 at the time of attachment, whereby the outer lid 9 and the inner plug 10 are integrally rotated. Thereby, the cap body 8 can be detached from the container body 2.

In the attaching/detaching mechanism 11A, when the locking convex portions 16a (locking portions 16) are locked to the locking concave portions 17a (locked portions 17), the clicking sensation can be imparted by the locking convex portions 16a passing over the lower surface side of the locking concave portions 17 a.

In the attachment/detachment mechanism 11A, the cap body 8 (cap unit 1A) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. At this time, the flange portion 10d of the inner plug 10 presses the upper wall portion 9b and the locking protrusion 16a of the outer lid 9 from the upper surface side. This can suppress vertical rattling of the cover 9, and reliably close the container body 2.

On the other hand, in the attaching/detaching mechanism 11A, the inner plug 10 is lifted up Fang Bachu from the opening 9c of the outer lid 9 by an operation opposite to the above operation, that is, by releasing the locking state of the locking convex portions 16a (locking portions 16) with respect to the locking concave portions 17a (locked portions 17), whereby the inner plug 10 can be detached from the outer lid 9.

That is, the detachable inner plug 10 from the outer cap 9 is limited to a state in which the cap body 8 is detached from the container body 2. In other words, in a state where the cap body 8 is attached to the container body 2, the inner plug 10 cannot be pulled upward Fang Bachu or the outer lid 9 cannot be pulled downward. Therefore, the inner plug 10 is not accidentally detached from the outer cap 9 in a state where the cap body 8 is attached to the container body 2.

As described above, in the cap unit 1A of the present embodiment, the inner plug 10 is detachably attached to the outer cap 9, so that the outer cap 9 and the inner plug 10 can be cleaned individually, and the space between the outer cap 9 and the inner plug 10 can be kept hygienic.

Therefore, in the capped container 100A provided with such a cap unit 1A, further improvement in convenience of use can be achieved.

Fig. 17 is a perspective view showing the state of the attaching/detaching mechanism 11B in a state where the inner plug 10 is in the detached position with respect to the outer cap 9 of the cap unit 1B. In the following description, the parts equivalent to the cap unit 1A are omitted from the description and the same reference numerals are given to the same parts in the drawings.

The cap unit 1B of the present embodiment is detachably attached to the container body 2 (not shown) to form a capped container 100B.

Specifically, as shown in fig. 7 to 17, the cap unit 1B includes a detachable mechanism 11B for detachably attaching the inner plug 10 to the outer cap 9, instead of the detachable mechanism 11A.

The attaching/detaching mechanism 11B includes: a locking portion 18 provided on one of the outer lid 9 and the inner plug 10 (in the present embodiment, the inner plug 10); and a locked portion 19 provided on the other side (in the present embodiment, the outer cover 9).

The locking portion 18 includes a plurality of (two in the present embodiment) hook portions 18a provided in the peripheral wall portion 10b of the inner plug 10. The two hooks 18a are provided at opposing positions on the back surface side of the inner plug 10 in the peripheral wall portion 10b of the inner plug 10. Each hook 18a is configured to have: a horizontal rib 20a protruding outward from an upper side of the peripheral wall portion 10b of the inner plug 10; a vertical rib wall 20b connecting a central portion between the flange portion 10d and the horizontal rib wall 20 a; and a pair of groove portions 20c located on both sides of the vertical rib wall 20b between the flange portion 10d and the horizontal rib wall 20 a.

On the other hand, the locked portion 19 has a plurality of (two in the present embodiment) notched recesses 19a provided around the opening 9c of the outer lid 9. The two notched recesses 19a are provided at positions facing each other across the opening 9c of the outer cover 9. Each cutout recess 19a is provided so as to cut out a part of the periphery of the opening 9c of the upper wall 9b in correspondence with the hook 18a.

In the attaching/detaching mechanism 11B, in the detached position shown in fig. 13 to 17, the notched recess 19a and the hooks 18a are aligned and the inner plug 10 is inserted from above into the opening 9c of the outer lid 9. Thus, the hooks 18a are inserted into the notch recesses 19a, and the flange 10d of the inner plug 10 is brought into contact with the upper wall 9b around the opening 9c of the outer lid 9, thereby engaging the inner plug 10 with the outer lid 9.

From this state, the inner plug 10 is pivoted to the outer cap 9, and thereby the locking portion 18 is locked to the locked portion 19 by locking the hook portions 18a with the periphery of the notch recess 19a in the attached position shown in fig. 8 to 12. Specifically, the upper wall 9b located around the notch recess 19a is in contact with the vertical rib 20b in a state of being inserted into the groove 20c constituting the hook 18 a. This allows the locking portion 18 to be locked to the locked portion 19, and the inner plug 10 to be attached to the outer lid 9.

The same applies to the case where the cap body 8 (cap unit 1B) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. That is, when the outer lid 9 of the cap main body 8 is gripped and rotated relative to the container main body 2, the upper wall portion 9b abuts against the vertical rib 20b, and the locking portion 18 is locked to the locked portion 19, so that the outer lid 9 and the inner plug 10 rotate integrally. Therefore, even if the outer lid 9 is kept at the removed position with respect to the inner plug 10, the outer lid 9 is rotated to naturally become the attachment position, and the cap main body 8 can be attached to the container main body 2 directly by a series of rotation operations.

The cap body 8 (cap unit 1B) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. At this time, the flange portion 10d of the inner plug 10 presses the upper wall portion 9b of the outer lid 9 from the upper surface side. This can suppress vertical rattling of the cover 9, and reliably close the container body 2.

In the attaching/detaching mechanism 11B of the present embodiment, the locking portion 18 can be locked to the locked portion 19 not only by rotating the inner plug 10 to one side of the axis with respect to the outer lid 9, but also by rotating the inner plug 10 to the other side of the axis, the locking portion 18 can be similarly locked to the locked portion 19.

In addition, when the cap body 8 (cap unit 1A) is removed from the container body 2, only the rotation direction is reversed, as in the case of mounting. That is, the outer lid 9 of the cap main body 8 is gripped and rotated in the opposite direction to the mounting direction with respect to the container main body 2, and the upper wall portion 9b is brought into contact with the vertical rib wall 20b from the opposite side to the mounting direction. At this time, the locking portion 18 is locked to the locked portion 19, and the outer lid 9 and the inner plug 10 rotate integrally. Thereby, the cap body 8 can be detached from the container body 2.

In the attaching/detaching mechanism 11B, the inner plug 10 is rotated from the detached position to one side or the other side around the center axis with respect to the outer lid 9, whereby the locking portion 18 can be locked to the locked portion 19. That is, when the inner plug 10 is rotated relative to the outer cap 9, it can be rotated in the order of the attachment position, the removal position, and the attachment position, the removal position being located between the two attachment positions on one side or the other side.

When the cap body 8 is attached to or detached from the container body 2, the outer cap 9 and the inner plug 10 are required to be in the attached positions, and rotate integrally. Therefore, the positions of the outer cap 9 and the inner plug 10 at the time of normal use are the mounting positions, as long as the user does not consciously select the removal position. Accordingly, the state in which the inner plug 10 is mounted to the outer cap 9 can be maintained without the user having to consciously select the mounting position, thereby facilitating.

On the other hand, in the attaching/detaching mechanism 11B, the inner plug 10 is rotated from the attached position to the detached position with respect to the outer lid 9 by rotating the inner plug 10 between the attached positions on one side or the other side with respect to the detached position to release the locked state of the locking portion 18 with respect to the locked portion 19.

At this time, the notched recess 19a and the hook 18a coincide with each other, and thus the inner plug 10 can be lifted up Fang Bachu from the opening 9c of the outer lid 9. Thereby, the inner plug 10 can be detached from the outer cap 9.

In the attaching/detaching mechanism 11B, when the inner plug 10 is inserted from above into the opening 9c of the outer lid 9 by aligning the cutout recess 19a with the hooks 18a, the click feeling can be imparted by the upper side of the peripheral wall portion 10B of the inner plug 10 passing over the upper wall portion 9B of the outer lid 9.

As described above, in the cap unit 1B of the present embodiment, the inner plug 10 is detachably attached to the outer cap 9, so that the outer cap 9 and the inner plug 10 can be cleaned individually, and the space between the outer cap 9 and the inner plug 10 can be kept hygienic.

Therefore, in the capped container 100B provided with such a cap unit 1B, further improvement in convenience of use can be achieved.

(third embodiment)

Next, as a third embodiment of the present invention, for example, a capped container 100C including a capping unit 1C shown in fig. 18 to 22 will be described.

Fig. 18 is a perspective view showing the external appearance of the cap unit 1C. Fig. 19 is a vertical cross-sectional view showing the structure of the cap unit 1C. Fig. 20 is a perspective view of the cap unit 1C from the lower side. Fig. 21 is a perspective view showing a state in which the inner plug 10 is detached from the outer cap 9 provided in the cap unit 1C. Fig. 22 is a perspective view showing the structure of the outer lid 9 provided in the cap unit 1C. In the following description, the parts equivalent to the cap unit 1A are omitted from the description and the same reference numerals are given to the same parts in the drawings.

The cap unit 1C of the present embodiment is detachably attached to the container body 2 (not shown), thereby forming a capped container 100C.

Specifically, as shown in fig. 18 to 22, the cap unit 1C includes a detachable mechanism 11C for detachably attaching the inner plug 10 to the outer lid 9, instead of the detachable mechanism 11A.

The attaching/detaching mechanism 11C includes: a locking portion 21 provided on one of the outer lid 9 and the inner plug 10 (in the present embodiment, the inner plug 10); and a locked portion 22 provided on the other side (in the present embodiment, the outer cover 9).

The locking portion 21 includes a plurality of (two in the present embodiment) plungers 21a provided below the flange portion 10d of the inner plug 10. The two plungers 21a are provided at opposing positions on the back surface side of the inner plug 10 below the flange portion 10d of the inner plug 10. Each plunger 21a has a structure capable of pressing a ball (or pin) provided at the outer tip thereof inward against the urging force of a spring provided at the inner side thereof. Each plunger 21a is attached in a state in which a ball (or pin) protrudes outward from the lower side of the flange portion 10d of the inner plug 10.

On the other hand, the locked portion 22 is constituted by an upper wall portion 9b provided around the opening portion 9c of the outer lid 9.

The attaching/detaching mechanism 11C further includes a positioning engagement portion 25, and the positioning engagement portion 25 is engaged with a first engagement portion 23 provided on the inner plug 10 and a second engagement portion 24 provided on the outer cap 9, thereby forming a rotation-stopping portion of the inner plug 10 with respect to the outer cap 9.

The first engagement portion 23 is formed of a pair of rib walls which face the lower side of the flange portion 10d of the inner plug 10 and protrude outward from the peripheral wall portion 10b of the inner plug 10 at a position orthogonal to the plunger 21a in a plan view.

On the other hand, the second engagement portion 24 is constituted by a pair of groove portions formed by cutting away an upper wall portion 9b provided around the opening portion 9c in the radial direction at positions opposed to each other across the opening portion 9c of the outer cover 9.

In the attaching/detaching mechanism 11C, the first engagement portion 23 and the second engagement portion 24 are aligned and the inner plug 10 is inserted from above into the opening 9C of the outer lid 9. Thereby, the first engagement portion 23 engages with the second engagement portion 24, and the flange portion 10d of the inner plug 10 is brought into contact with the upper wall portion 9b located around the opening 9c of the outer lid 9, thereby engaging the inner plug 10 with the outer lid 9.

At this time, the plungers 21a are locked to the upper wall 9b provided around the opening 9c of the outer cover 9, so that the locked portions 21 are locked to the locked portions 22. Thereby, the inner plug 10 can be attached to the outer cap 9.

In the attaching/detaching mechanism 11C, click feeling can be given when each plunger 21a passes over the upper wall 9b.

In the attachment/detachment mechanism 11C, the cap body 8 (cap unit 1C) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. At this time, the flange portion 10d of the inner plug 10 presses the upper wall portion 9b of the outer lid 9 from the upper surface side. This can suppress vertical rattling of the cover 9, and reliably close the container body 2.

Further, the first engaging portion 23 of the positioning engaging portion 25 engages with the second engaging portion 24, whereby the outer lid 9 and the inner plug 10 are integrally rotated. Therefore, the cap body 8 can be attached to the container body 2 by rotating the outer lid 9 by holding it.

In addition, when the cap body 8 (cap unit 1C) is removed from the container body 2, only the rotation direction is reversed, as in the case of mounting. That is, the outer lid 9 of the cap main body 8 is gripped and rotated in the opposite direction to the direction of the container main body 2 at the time of attachment, whereby the outer lid 9 is rotated integrally with the inner plug 10. Thereby, the cap body 8 can be detached from the container body 2.

On the other hand, in the attaching/detaching mechanism 11C, the inner plug 10 is detached from the outer lid 9 by an operation opposite to the above operation, that is, by releasing the locked state of the plungers 21a (the locking portions 21) with respect to the locked portions 22 and lifting the inner plug 10 upward Fang Bachu from the opening 9C of the outer lid 9.

As described above, in the cap unit 1C of the present embodiment, the inner plug 10 is detachably attached to the outer cap 9, so that the outer cap 9 and the inner plug 10 can be cleaned individually, and the space between the outer cap 9 and the inner plug 10 can be kept hygienic.

Therefore, in the capped container 100C provided with such a cap unit 1C, further improvement in convenience of use can be achieved.

(fourth embodiment)

Next, as a fourth embodiment of the present invention, a capped container 100D provided with a capped unit 1D shown in fig. 23 to 25, for example, will be described.

Fig. 23 is a perspective view showing the external appearance of the cap unit 1D. Fig. 24 is a vertical cross-sectional view showing the structure of the cap unit 1D. Fig. 25 is a perspective view showing a state in which the inner plug 10 is detached from the outer cap 9 provided in the cap unit 1D. In the following description, the parts equivalent to the cap unit 1A are omitted from the description and the same reference numerals are given to the same parts in the drawings.

The cap unit 1D of the present embodiment is detachably attached to the container body 2 (not shown), thereby forming a capped container 100D.

Specifically, as shown in fig. 23 to 25, the cap unit 1D includes a detachable mechanism 11D for detachably attaching the inner plug 10 to the outer lid 9, instead of the detachable mechanism 11A.

The attaching/detaching mechanism 11D includes: a locking portion 26 provided on one of the outer lid 9 and the inner plug 10 (in the present embodiment, the outer lid 9); the engaged portion 27 is provided on the other side (the inner plug 10 in the present embodiment).

The locking portion 26 has a locking convex portion 26a, and the locking convex portion 26a is provided around the opening 9c of the outer lid 9 except for a first engagement portion 28 described later. The locking convex portion 26a is provided so as to protrude inward in the horizontal direction from an upper wall portion 9b provided around the opening portion 9c of the outer lid 9.

On the other hand, the engaged portion 27 has an engaging recess 27a, and the engaging recess 27a is provided on the inner side of the lower surface of the flange portion 10d which is the outer peripheral portion of the inner plug 10, over the entire circumference. The locking concave portion 27a is provided so as to recess the inner side of the lower surface of the flange portion 10d inward over the entire circumference corresponding to the locking convex portion 26 a.

The attaching/detaching mechanism 11D further includes a positioning engagement portion 30, and the positioning engagement portion 30 is engaged with a first engagement portion 28 provided in the outer lid 9 and a second engagement portion 29 provided in the inner plug 10, thereby forming a rotation-preventing portion of the inner plug 10 with respect to the outer lid 9.

The first engagement portion 28 has a plurality of (two in the present embodiment) engagement projections 28a provided around the opening 9c of the outer cover 9. The two locking projections 28a are provided at positions facing each other across the opening 9c of the outer cover 9, and protrude inward from between a pair of grooves 28b formed by cutting away the upper wall 9b provided around the opening 9c in the radial direction.

On the other hand, the second engagement portion 29 has a plurality of (two in the present embodiment) engagement concave portions 29a provided below the flange portion 10d of the inner plug 10. The two locking recesses 29a are provided at opposing positions on the back surface side of the inner plug 10 below the flange portion 10d of the inner plug 10. Each of the locking concave portions 29a is provided so that a part of the lower peripheral side of the flange portion 10d is cut out in correspondence with the locking convex portion 28a.

In the attaching/detaching mechanism 11D, the first engagement portion 28 and the second engagement portion 29 are aligned and the inner plug 10 is inserted from above into the opening 9c of the outer lid 9. Thus, the first engagement portion 28 engages with the second engagement portion 29, and the locking convex portion 26a is locked to the locking concave portion 27a by elastic deformation (flexing) of the outer lid 9, so that the locking portion 26 is locked to the locked portion 27 in a state in which the flange portion 10d of the inner plug 10 is brought into contact with the periphery of the opening portion 9c of the outer lid 9. Thereby, the inner plug 10 can be attached to the outer cap 9.

That is, the locking of the locked portion 27 and the locking portion 26 in the attaching/detaching mechanism 11D is based on elastic deformation (deflection) of the outer cap 9, and the outer cap 9 and the inner cap 10 are integrated by relatively weak locking of the locked portion 27 provided in the inner cap 10 and the locking portion 26 provided in the outer cap 9.

In the attachment/detachment mechanism 11D, click feeling can be imparted when the locking convex portions 26a (locking portions 26) are locked in the locking concave portions 27a (locked portions 27).

The cap body 8 (cap unit 1D) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. At this time, the flange portion 10d of the inner plug 10 presses the upper wall portion 9b of the outer lid 9 from the upper surface side. This can suppress vertical rattling of the cover 9, and reliably close the container body 2.

Further, the first engagement portion 28 of the positioning engagement portion 30 engages with the second engagement portion 29, whereby the outer lid 9 and the inner plug 10 are integrally rotated. Therefore, the cap body 8 can be attached to the container body 2 by rotating the outer lid 9 by holding it.

In addition, when the cap body 8 (cap unit 1D) is removed from the container body 2, only the rotation direction is reversed, as in the case of mounting. That is, the outer lid 9 of the cap main body 8 is gripped and rotated in the opposite direction to the direction of the container main body 2 at the time of attachment, whereby the outer lid 9 is rotated integrally with the inner plug 10. Thereby, the cap body 8 can be detached from the container body 2.

On the other hand, in the attaching/detaching mechanism 11D, the inner plug 10 is lifted up Fang Bachu from the opening 9c of the outer lid 9 by an operation opposite to the above operation, that is, by releasing the locking state of the locking convex portions 26a (locking portions 26) with respect to the locking concave portions 27a (locked portions 27), so that the inner plug 10 can be detached from the outer lid 9.

As described above, in the cap unit 1D of the present embodiment, the inner plug 10 is detachably attached to the outer cap 9, so that the outer cap 9 and the inner plug 10 can be cleaned individually, and the space between the outer cap 9 and the inner plug 10 can be kept hygienic.

Therefore, in the capped container 100D provided with such a cap unit 1D, further improvement in convenience of use can be achieved.

(fifth embodiment)

Next, as a fifth embodiment of the present invention, for example, a capped container 100E provided with a capping unit 1E shown in fig. 26 to 28 will be described.

Fig. 26 is a perspective view showing a state in which the inner plug 10 is detached from the outer cap 9 provided in the cap unit 1E. Fig. 27 is a perspective view showing the structure of the outer lid 9 provided in the cap unit 1E. Fig. 28 is a perspective view showing the structure of the inner plug 10 provided in the cap unit 1E. In the following description, the parts equivalent to the cap units 1A, 1B, and 1C are not described and the same reference numerals are given to the drawings.

The cap unit 1E of the present embodiment is detachably attached to the container body 2 (not shown), thereby forming a capped container 100E.

Specifically, as shown in fig. 26 to 28, the cap unit 1E includes a detachable mechanism 11E for detachably attaching the inner plug 10 to the outer cap 9, instead of the detachable mechanism 11A.

The attaching/detaching mechanism 11E has a structure in which the attaching/detaching mechanisms 11B and 11C are combined, and includes: a plurality of (two in the present embodiment) hook portions 18a are locking portions 18 provided in either one (in the present embodiment, the inner plug 10) of the outer lid 9 and the inner plug 10; a plurality of (two in the present embodiment) notched recesses 19a serve as engaged portions 19 provided on any other (the outer cover 9 in the present embodiment); a plurality of (two in the present embodiment) plungers 21a are locking portions 21 provided in either one (in the present embodiment, the inner plug 10) of the outer cap 9 and the inner plug 10; and a plurality of (two in the present embodiment) locking recesses 22a serving as locked portions 22 provided on any other (the outer cover 9 in the present embodiment).

The two hooks 18a and the two plungers 21a are disposed so as to face the peripheral wall 10b of the plug 10 and are disposed at positions orthogonal to each other in a plan view. On the other hand, the two cutout recesses 19a and the two locking recesses 22a are disposed so as to face each other across the opening 9c of the outer cover 9, and are disposed at positions orthogonal to each other in a plan view.

Each of the locking concave portions 22a is provided between a pair of locking convex portions 22b, and the pair of locking convex portions 22b protrude downward from the inner peripheral lower surface of the upper wall portion 9b provided around the opening portion 9c of the outer lid 9.

In the attaching/detaching mechanism 11E, the inner plug 10 is inserted from above into the opening 9c of the outer lid 9 by aligning the notched recess 19a with the hooks 18 a. Accordingly, the hooks 18a are inserted into the notched recesses 19a, the plungers 21a are inserted into the locking recesses 22a, and the flange 10d of the inner plug 10 is brought into contact with the upper wall 9b around the opening 9c of the outer lid 9, thereby engaging the inner plug 10 with the outer lid 9.

Here, when the plungers 21a are inserted into the locking recesses 22a, the plungers 21a pass over the inner peripheral end portion of the upper wall portion 9b of the outer lid 9, and thereby the inner plug 10 is engaged with the outer lid 9 in the up-down direction. That is, when the inner plug 10 is pulled upward from the outer lid 9, the plungers 21a need to pass over the inner peripheral end portion of the upper wall portion 9b of the outer lid 9 again. Therefore, the locking portion 21 and the locked portion 22 also function as temporary fixing means in the up-down direction.

When the plungers 21a are inserted into the locking recesses 22a, the plungers 21a pass over the inner peripheral end portion of the upper wall portion 9b of the outer cover 9, whereby click feeling can be imparted.

From this state, the inner plug 10 is pivoted to the outer cap 9, whereby the hooks 18a are engaged with the periphery of the cutout recesses 19a in the mounted position shown in fig. 9 to 12. At this time, each plunger 21a is locked to the upper wall 9b provided around the opening 9c of the outer cover 9 beyond the locking protrusion 22 b. Thereby, the inner plug 10 can be attached to the outer cap 9.

The same applies to the case where the cap body 8 (cap unit 1E) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. That is, when the outer lid 9 of the cap main body 8 is gripped and rotated relative to the container main body 2, the upper wall portion 9b abuts against the vertical rib 20b, and the locking portion 18 is locked to the locked portion 19, so that the outer lid 9 and the inner plug 10 rotate integrally. Therefore, even if the outer lid 9 is kept at the removed position with respect to the inner plug 10, the outer lid 9 is rotated to naturally become the attachment position, and the cap main body 8 can be attached to the container main body 2 directly by a series of rotation operations.

The cap body 8 (cap unit 1E) is attached to the container body 2 by screwing the male screw portion 14 of the inner plug 10 and the female screw portion 6 of the container body 2. At this time, the flange portion 10d of the inner plug 10 presses the upper wall portion 9b of the outer lid 9 from the upper surface side. This can suppress vertical rattling of the cover 9, and reliably close the container body 2.

In the attaching/detaching mechanism 11E of the present embodiment, the locking portion 18 can be similarly locked to the locked portion 19 by rotating the inner plug 10 not only to one side of the shaft with respect to the outer cap 9 but also to the other side of the shaft.

In addition, when the cap body 8 (cap unit 1E) is removed from the container body 2, only the rotation direction is reversed, as in the case of mounting. That is, the outer lid 9 of the cap main body 8 is gripped and rotated in the opposite direction to the mounting direction with respect to the container main body 2, and the upper wall portion 9b is brought into contact with the vertical rib wall 20b from the opposite side to the mounting direction. At this time, the locking portion 18 is locked to the locked portion 19, and the outer lid 9 and the inner plug 10 rotate integrally. Thereby, the cap body 8 can be detached from the container body 2.

In the attaching/detaching mechanism 11E, the inner plug 10 is rotated from the detached position to one side or the other side around the center axis with respect to the outer lid 9, whereby the locking portion 18 can be locked to the locked portion 19. That is, when the inner plug 10 is rotated relative to the outer cap 9, it can be rotated in the order of the attachment position, the removal position, and the attachment position, the removal position being located between the two attachment positions on one side or the other side.

In the attachment/detachment mechanism 11E, click feeling can be imparted by passing over the locking convex portion 22b when each plunger 21a rotates between the two attachment positions and the removal position.

On the other hand, in the attaching/detaching mechanism 11E, the inner plug 10 is rotated from the attachment position to the detachment position with respect to the outer lid 9 by rotating the inner plug 10 between the attachment positions on one side and the other side with respect to the outer lid 9 to release the locked state of the locking portion 18 with respect to the locked portion 19.

At this time, the notched recess 19a and the hook 18a are aligned, and the inner plug 10 can be lifted up Fang Bachu from the opening 9c of the outer lid 9. Thereby, the inner plug 10 can be detached from the outer cap 9.

The engagement recesses 22a and the plungers 21a are merely means for transmitting the engagement recesses 19a and the hooks 18a (in the removed position) to the user in an easily understood manner. That is, if the locked portions 19 and 18 are not provided, the plungers 21a can pass over the inner peripheral end portion of the upper wall portion 9b of the outer cover 9 in the upward direction from any position.

As described above, in the cap unit 1E of the present embodiment, the inner plug 10 is detachably attached to the outer cap 9, so that the outer cap 9 and the inner plug 10 can be cleaned individually, and the space between the outer cap 9 and the inner plug 10 can be kept hygienic.

Therefore, in the capped container 100E provided with such a cap unit 1E, further improvement in convenience of use can be achieved.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.

For example, the cap units 1A to 1E are configured to attach the inner plug 10 to the container body 2 by screwing in a state of being fitted from the upper opening 2a of the container body 2, but the present invention is not necessarily limited to such a configuration. For example, the cap units 1A to 1E may be configured such that the outer cap 9 is attached to the container body 2 by screwing in a state where the upper opening 2a of the container body 2 is covered from the outside.

In this configuration, the outer cap 9 (cap body 8) may be detachably attached to the container body 2 by screwing a male screw portion provided on the outer peripheral surface of the neck portion 2d and a female screw portion provided on the inner peripheral surface of the peripheral wall portion 9a constituting the outer cap 9, instead of the female screw portion 6 and the male screw portion 14.

The capped containers 100A to 100E are configured to directly open and close the upper opening 2a of the container body 2, but are not necessarily limited to such a configuration. For example, the cap units 1A to 1E may be detachably attached to shoulder members attached to the container body 2.

The lid may be attached to a cap body attached to the container body 2 so as to be openable and closable. In this case, the lid may be attached to the cap body by screwing, or the lid may be rotatably attached to the cap body via a hinge portion.

In the above-described embodiment, the case where the present invention is applied to a beverage container having a heat retaining function (or a cooling retaining function) due to the container body 2 having the vacuum heat insulating structure described above has been exemplified, but the present invention can be widely applied to a capped container having a container body and a lid detachably attached to the container body.
