Description

Technical Field

[0001] This invention relates to a cap unit and a container with a cap. Background Technology

[0002] Previously, there were capped containers with a cap unit (plug) that sealed the upper opening of the container body by being installed in a detachable manner on the neck of the container body (see, for example, Patent Documents 1 and 2 below).

[0003] Such a cap unit has an outer cap that covers the neck of the container body and an inner plug that is inserted into the inside of the container body from the upper opening. The outer cap or the inner plug is installed on the cap body by screwing.

[0005] Patent Document 2: Japanese Patent Application Publication No. 2019-001539

[0006] However, in the aforementioned capped container, the area between the outer cap and the inner plug is very difficult to clean when cleaning the cap unit. Therefore, a structure that can be divided into an outer cap and an inner plug is adopted in the cap unit to improve cleanability.

[0007] However, in existing cap units, where the structure can be divided into an outer cap and an inner bolt, there are problems such as the structure (installation and removal mechanism) for installing the inner bolt onto the outer cap becoming more complicated. Summary of the Invention

[0008] The present invention was made in view of the existing situation, and its object is to provide a cap unit that simplifies the construction of installing the inner plug on the outer cover and improves the cleanability of the outer cover and the inner plug, and a capped container that can achieve further improvement in ease of use by having such a cap unit.

[0009] To achieve the above objectives, the present invention provides the following apparatus.

Detailed Implementation

[0077] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0078] (First Implementation)

[0079] First, as a first embodiment of the present invention, for example, a device having Figures 1-6The capped container 100A of the capped unit 1A shown will be described.

[0080] also, Figure 1 This is a perspective view showing the appearance of a capped container 100A with capped unit 1A. Figure 2 This is a vertical sectional view showing the structure of a capped container 100A having a capped unit 1A. Figure 3 This is a perspective view showing the state in which the inner bolt 10 has been removed from the outer cover 9 of the cap unit 1A. Figure 4 This is a perspective view of the outer cover 9 of the cap unit 1A as viewed from below. Figure 5 This is a perspective view of the inner bolt 10 of the cap unit 1A as observed from below. Figure 6 This is a perspective view obtained by observing the inner bolt 10 of the cap unit 1A from a lower side.

[0081] like Figure 1 and Figure 2 As shown, the capped container 100A of this embodiment has a container body 2 with an opening at the top and a cap unit 1A that can be easily installed and removed from the container body 2. It is a beverage container that can keep the beverage (contents) contained in the container body 2 warm or cold.

[0082] Specifically, the container body 2 has an outer container 3 made of metal, such as stainless steel, and an inner container 4. The container body 2 has a vacuum insulation structure, in which the inner container 4, which is open at one end, is housed inside the outer container 3, which is open at one end. The vacuum insulation structure joins the open ends of the inner container with each other, and a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4.

[0083] The vacuum insulation layer 5 can be formed, for example, by sealing the vent hole located at the center of the bottom surface of the outer container 3 with solder within a chamber that has been depressurized (evacuated) to a high vacuum.

[0084] By incorporating this vacuum insulation structure within the container body 2, the aforementioned functions of heat preservation or cold preservation are achieved. Furthermore, this vacuum insulation structure in the container body 2 creates a state where the difference between internal pressure (vacuum pressure) and external pressure (atmospheric pressure) constantly applies tension to the outer container 3 and the inner container 4, thereby increasing the mechanical strength of the outer container 3 and the inner container 4. Consequently, even with a relatively thin outer container 3 and inner container 4, the rigidity of the container body 2 can be improved, enabling a lightweight design for the container body 2.

[0085] The container body 2 has: a generally circular bottom portion 2b; a main body portion 2c that rises from the outer periphery of the bottom portion 2b in a generally cylindrical shape; and a neck portion 2d that rises from the upper side of the main body portion 2c in a generally cylindrical shape. In addition, the upper end opening of the neck portion 2d is circular, serving as the upper opening portion 2a of the container body 2.

[0086] An internal thread portion 6 is provided on the inner circumferential surface of the neck 2d. Furthermore, below the internal thread portion 6, an annular protrusion 7 is provided protruding from the inner circumference of the inner container 4 all around the circumference.

[0087] Furthermore, the capped container 100A of this embodiment has a generally cylindrical shape, but the shape of the capped container 100A is not particularly limited and can be appropriately modified according to size, appearance design, etc. In addition, coating, printing, etc. can also be applied to the outer peripheral surface of the container body 2 (outer container 3).

[0088] In this embodiment, the cap unit 1A constitutes a cap that opens and closes the upper opening 2a of the container body 2. Specifically, as... Figures 2-6 As shown, the cap unit 1A has a cap body 8 that seals the upper opening 2a of the container body 2 when it is inserted into the inner side of the container body 2 from the upper opening 2a, and has a structure for mounting the cap body 8 relative to the container body 2 by screwing.

[0089] The cap body 8 has: an outer cap 9 that surrounds the upper part of the container body 2; an inner plug 10 that is inserted into the inner side of the container body 2 from the upper opening 2a; and a disassembly and assembly mechanism 11A that installs the inner plug 10 onto the outer cap 9 in a manner that allows for easy disassembly and assembly.

[0090] like Figure 2 and Figure 4 As shown, the outer cover 9 is made of heat-resistant resin, for example, and has: a peripheral wall portion 9a, which is formed in a generally cylindrical shape in a manner that is continuous with the main body portion 2c of the container body 2; an upper wall portion 9b, which covers the upper outer periphery of the peripheral wall portion 9a throughout the entire circumference; and an opening portion 9c, which has a generally circular opening at the center of the upper wall portion 9b.

[0091] like Figure 2 , Figure 5 and Figure 6 As shown, the inner plug 10 is made of, for example, heat-resistant resin and has: a generally circular bottom wall portion 10a; a peripheral wall portion 10b that rises from the periphery of the bottom wall portion 10a in a generally cylindrical shape; a top wall portion 10c that blocks the upper part of the peripheral wall portion 10b; and a flange portion 10d that protrudes further in the diameter-expanding direction than the peripheral wall portion 10b.

[0092] The inner plug 10 has a lower plug member 12 with a bottom and a generally cylindrical shape forming a bottom wall portion 10a and a peripheral wall portion 10b, and an upper plug member 13 with a generally circular shape forming a top wall portion 10c and a flange portion 10d. The lower plug member 12 is integrally mounted to the lower surface of the upper plug member 13 by means of welding or the like. Furthermore, the interior of the inner plug 10 is not limited to air as a heat insulation layer, but can also be a structure in which heat insulation material S is disposed.

[0093] Furthermore, an external threaded portion 14 is provided on the outer peripheral surface of the peripheral wall portion 10b (inner plug 10). In the capped container 100A, the cap body 8 (cap unit 1A) is installed relative to the container body 2 in a manner that allows for easy installation and removal by screwing the external threaded portion 14 into the internal threaded portion 6. Moreover, the internal threaded portion 6 and the external threaded portion 14 are composed of two threads with complementary shapes. When using two threads, the cap body 8 (cap unit 1A) can be installed and removed relative to the container body 2 with fewer rotation operations (approximately 180° in this embodiment).

[0094] A water-stop seal 15 is integrally installed on the outer periphery of the lower end side of the inner plug 10. The water-stop seal 15 is an annular sealing component that seals the protrusion 7 of the container body 2 with the inner plug 10. It is made of, for example, heat-resistant rubber such as silicone rubber, or elastic components such as elastomers. The water-stop seal 15 is integrally formed with the inner plug 10 (cap body 8) by insert forming as described later.

[0095] The inner plug 10 has: a first recess 10e, the shape of which corresponds to a first protrusion 15a protruding inward from the upper end of the inner circumferential side of the water-stop seal 15; and a second recess 10f, the shape of which corresponds to a second protrusion 15b protruding upward from the lower end of the inner circumferential side of the water-stop seal 15. Additionally, the inner plug 10 has a third protrusion 10g, which is located between the first protrusion 15a and the second protrusion 15b of the water-stop seal 15 and its shape corresponds to the third recess 15c of the water-stop seal 15 formed between the first recess 10e and the second recess 10f of the inner plug 10.

[0096] In the cap unit 1A of this embodiment, the first protrusion 15a of the water-stop seal 15 protruding inward is integrally formed with the first recess 10e of the inner plug 10, and the second protrusion 15b of the water-stop seal 15 protruding upward is integrally formed with the second recess 10f of the inner plug 10. Furthermore, the third recess 15c of the water-stop seal 15 and the third protrusion 10g of the inner plug 10 are integrally formed, thereby utilizing their respective anchoring effects to improve the tightness of the water-stop seal 15 installed integrally with the inner plug 10 (cap body 8).

[0097] Furthermore, the lower surface of the inner plug 10 has a shape that recesses the bottom wall portion 10a upwards, and is coplanar with the lower surface of the water-stop seal 15. Therefore, the water-stop seal 15 is difficult to detach 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. Additionally, there are no gaps near the boundary, so water droplets do not easily accumulate, ensuring hygiene.

[0098] Furthermore, two elastic flange portions 15d are provided on the outer peripheral surface of the water-stop seal 15, protruding in the expansion direction. When the cap body 8 (cap unit 1A) is installed on the container body 2, the elastic flange portions 15d of the water-stop seal 15 elastically deform, becoming a state in which the protrusion 7 is tightly attached to the container body 2 throughout its entire circumference. As a result, the protrusion 7 (container body 2) and the inner plug 10 (cap body 8) can be sealed (water-stopped).

[0099] Furthermore, the water-stopping seal 15 is not necessarily limited to the shape described above. For example, the number of elastic flange portions 15d is not limited to the two mentioned above, but can be one or more.

[0100] Furthermore, the water-stop seal 15 is not necessarily limited to the structure with the aforementioned elastic flange portion 15d, and its shape and other features can be appropriately modified. For example, it may also be a structure with an elastic flange portion having a shape that bends downward from the upper end of the outer peripheral surface of the water-stop seal 15.

[0101] like Figures 2-6 As shown, the disassembly and assembly mechanism 11A includes: a locking part 16, which is provided on either the outer cover 9 or the inner bolt 10 (the outer cover 9 in this embodiment); and a locked part 17, which is provided on the other (the inner bolt 10 in this embodiment).

[0102] The locking portion 16 has a plurality of (two in this embodiment) locking protrusions 16a disposed around the opening 9c of the outer cover 9. The two locking protrusions 16a are configured to protrude inward in the horizontal direction from opposite positions across the opening 9c of the outer cover 9.

[0103] On the other hand, the locking portion 17 has a plurality of (two in this embodiment) locking recesses 17a disposed on the inner side of the lower surface of the flange portion 10d, which forms the outer periphery of the inner bolt 10. The two locking recesses 17a are disposed on the inner side of the back side of the inner bolt 10 on the inner side of the lower surface of the flange portion 10d. Each locking recess 17a is located between a pair of ribs 17b protruding outward from the inner side of the lower surface of the flange portion 10d of the inner bolt 10 and the flange portion 10d, and is configured to recess a portion of the upper bolt member 13.

[0104] In the disassembly / removal mechanism 11A, the inner bolt 10 is inserted from above relative to the opening 9c of the outer cover 9. Each locking protrusion 16a passes over the lower surface of the locking recess 17a due to the elastic deformation (flexion) of the outer cover 9. At this time, with the flange 10d of the inner bolt 10 abutting against the periphery of the opening 9c of the outer cover 9, each locking protrusion 16a is locked into each locking recess 17a, thus the locking portion 16 is locked into the locked portion 17. Therefore, the inner bolt 10 can be installed on the outer cover 9.

[0105] That is, the locking part 17 and the locking part 16 in the disassembly and assembly mechanism 11A are locked based on the elastic deformation (flexure) of the outer cover 9. The outer cover 9 and the inner bolt 10 are integrated by the locking part 17 provided in the inner bolt 10 and the locking part 16 provided in the outer cover 9.

[0106] In the disassembly and assembly mechanism 11A, each locking recess 17a is located between a pair of ribs 17b, and each locking protrusion 16a is locked in the locking recess 17a, thereby restricting the left-right (rotational) movement of each locking protrusion 16a.

[0107] Therefore, when the outer cover 9 is held and the cap body 8 (cap unit 1A) is rotated about the central axis, each locking protrusion 16a abuts against a pair of ribs 17b from the inner wall side, and thus the outer cover 9 and the inner plug 10 rotate as a unit. Therefore, the cap body 8 can be installed on the container body 2 by holding the outer cover 9 and rotating it.

[0108] Furthermore, when removing the cap body 8 (cap unit 1A) from the container body 2, the rotation direction is simply reversed, just as during installation. That is, by holding the outer cover 9 of the cap body 8 and rotating it relative to the container body 2 in the opposite direction to the installation direction, the outer cover 9 and the inner plug 10 rotate as a unit. Thus, the cap body 8 can be removed from the container body 2.

[0109] Furthermore, in the disassembly and assembly mechanism 11A, when each locking protrusion 16a (locking portion 16) is locked in each locking recess 17a (locked portion 17), each locking protrusion 16a passes over the lower surface side of the locking recess 17a, thereby providing a click sensation.

[0110] Furthermore, in the disassembly and assembly mechanism 11A, the cap body 8 (cap unit 1A) is installed on the container body 2 by screwing the external thread 14 of the inner bolt 10 into the internal thread 6 of the container body 2. At this time, the flange 10d of the inner bolt 10 presses against the upper wall 9b and the locking protrusion 16a of the outer cover 9 from the upper surface side. As a result, the vertical shaking of the outer cover 9 can be suppressed, and the container body 2 can be reliably sealed.

[0111] On the other hand, in the disassembly and assembly mechanism 11A, by performing an action opposite to the above-mentioned action, that is, by releasing the locking state of each locking protrusion 16a (locking part 16) relative to each locking recess 17a (locked part 17), the inner bolt 10 is pulled upward from the opening 9c of the outer cover 9, thereby allowing the inner bolt 10 to be removed from the outer cover 9.

[0112] That is, the ability to remove the inner plug 10 from the outer cover 9 is limited to the state where the cap body 8 has been removed from the container body 2. In other words, with the cap body 8 installed on the container body 2, it is impossible to pull the inner plug 10 upwards or pull the outer cover 9 downwards. Therefore, with the cap body 8 installed on the container body 2, the inner plug 10 will not be accidentally removed from the outer cover 9.

[0113] As described above, in the cap unit 1A of this embodiment, by forming a structure in which the inner plug 10 is installed on the outer cover 9 in a way that allows for easy installation and removal, the outer cover 9 and the inner plug 10 can be cleaned separately, and the outer cover 9 and the inner plug 10 can be kept hygienically in contact.

[0114] Therefore, in a capped container 100A equipped with such a capping unit 1A, the ease of use can be further improved.

[0118] In this embodiment, the cap unit 1B is installed on the container body 2 (not shown) in a manner that allows for easy assembly and disassembly to form a capped container 100B.

[0119] Specifically, such as Figures 7 to 17 As shown, the cap unit 1B has a disassembly and assembly mechanism 11B that allows the inner bolt 10 to be installed and removed from the outer cover 9 in a way that replaces the aforementioned disassembly and assembly mechanism 11A.

[0120] The disassembly and assembly mechanism 11B includes: a locking part 18, which is provided on either the outer cover 9 or the inner bolt 10 (in this embodiment, the inner bolt 10); and a locked part 19, which is provided on the other (in this embodiment, the outer cover 9).

[0121] The locking portion 18 has a plurality of hook portions 18a (two in this embodiment) disposed on the peripheral wall portion 10b of the inner bolt 10. The two hook portions 18a are disposed opposite each other on the back side of the inner bolt 10 on the peripheral wall portion 10b of the inner bolt 10. Each hook portion 18a is configured to have: a horizontal rib wall 20a protruding outward from the upper part of the peripheral wall portion 10b of the inner bolt 10; a vertical rib wall 20b connecting the central portion between the flange portion 10d and the horizontal rib wall 20a; 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 20a.

[0122] On the other hand, the locking portion 19 has a plurality of (two in this embodiment) cutout recesses 19a provided around the opening 9c of the outer cover 9. The two cutout recesses 19a are positioned opposite each other across the opening 9c of the outer cover 9. Each cutout recess 19a is configured to cut off a portion around the opening 9c of the upper wall portion 9b in accordance with the hook portion 18a.

[0123] In the disassembly and assembly mechanism 11B, Figures 13-17In the disassembly position shown, the inner bolt 10 is inserted from above into the opening 9c of the outer cover 9, aligning the recessed sections 19a and the hooks 18a. Thus, the hooks 18a are inserted into the inside of the recessed sections 19a, and the flange 10d of the inner bolt 10 abuts against the upper wall 9b surrounding the opening 9c of the outer cover 9, thereby engaging the inner bolt 10 with the outer cover 9.

[0124] From this state, by rotating the inner bolt 10 relative to the outer cover 9 to one side about the axis, thereby... Figures 8-12 The installation position shown is such that the locking part 18 is locked to the locked part 19 by the surrounding engagement of each hook part 18a and each cut recess 19a. Specifically, the upper wall part 9b surrounding the cut recess 19a abuts against the vertical rib wall 20b when inserted into the groove 20c constituting the hook part 18a. Thus, the locking part 18 is locked to the locked part 19, allowing the inner bolt 10 to be installed on the outer cover 9.

[0125] Furthermore, the same applies when the cap body 8 (cap unit 1B) is installed on the container body 2 by screwing the external thread 14 of the inner plug 10 into the internal thread 6 of the container body 2. That is, if the outer cap 9 of the cap body 8 is held and rotated relative to the container body 2, the upper wall 9b abuts against the vertical rib 20b, thereby locking the locking part 18 at the locked part 19, and the outer cap 9 and the inner plug 10 rotate together. Therefore, even assuming that the outer cap 9 remains in the removed position relative to the inner plug 10, rotating the outer cap 9 naturally creates an installation position, and the cap body 8 can be directly installed on the container body 2 through a series of rotational actions.

[0126] Furthermore, the cap body 8 (cap unit 1B) is installed on the container body 2 by screwing the external thread 14 of the inner plug 10 into the internal thread 6 of the container body 2. At this time, the flange 10d of the inner plug 10 presses against the upper wall 9b of the outer cover 9 from the upper surface side. As a result, the vertical shaking of the outer cover 9 can be suppressed, and the container body 2 can be reliably sealed.

[0127] Furthermore, in the disassembly and assembly mechanism 11B of this embodiment, not only can the locking part 18 be locked to the locked part 19 by rotating the inner bolt 10 relative to the outer cover 9 around the axis, the locking part 18 can also be locked to the locked part 19 by rotating the inner bolt 10 around the axis.

[0128] Furthermore, when removing the cap body 8 (cap unit 1A) from the container body 2, the rotation direction is simply reversed, just as during installation. That is, by holding the outer cover 9 of the cap body 8 and rotating it relative to the container body 2 in the opposite direction to the installation direction, the upper wall portion 9b abuts against the vertical rib wall 20b from the side opposite to the installation direction. At this time, the locking portion 18 is locked in the locking portion 19, and the outer cover 9 and the inner plug 10 rotate as a unit. Thus, the cap body 8 can be removed from the container body 2.

[0129] In the disassembly and assembly mechanism 11B, by rotating the inner bolt 10 from its disassembled position relative to the outer cover 9 to one side or the other about the central axis, the locking part 18 can be locked into the locking part 19. That is, when the inner bolt 10 is rotated relative to the outer cover 9, it can rotate in the order of installation position, disassembled position, and installation position, with the disassembled position located between the two installation positions on one side or the other side.

[0130] When the cap body 8 is installed on or removed from the container body 2, the outer cap 9 and inner plug 10 are always in the installation position and rotate as a unit. Therefore, unless the user consciously chooses the removal position, the position of the outer cap 9 and inner plug 10 during normal use is the installation position. Thus, the inner plug 10 can be kept installed on the outer cap 9 without the user consciously choosing the installation position, which is convenient.

[0131] On the other hand, in the disassembly and assembly mechanism 11B, the locking state of the locking part 18 relative to the locked part 19 is released by rotating the inner bolt 10 relative to the outer cover 9 in such a way that the removal position is located between two installation positions on one side or the other side, thereby rotating the inner bolt 10 relative to the outer cover 9 from the installation position to the removal position.

[0132] At this point, the recessed portions 19a and hook portions 18a are aligned, allowing the inner bolt 10 to be pulled upwards from the opening 9c of the outer cover 9. Thus, the inner bolt 10 can be removed from the outer cover 9.

[0133] That is, the ability to remove the inner plug 10 from the outer cover 9 is limited to the state where the cap body 8 has been removed from the container body 2. In other words, with the cap body 8 installed on the container body 2, it is impossible to pull the inner plug 10 upwards or pull the outer cover 9 downwards. Therefore, with the cap body 8 installed on the container body 2, the inner plug 10 will not be accidentally removed from the outer cover 9.

[0134] Furthermore, in the disassembly and assembly mechanism 11B, when the inner bolt 10 is inserted from above relative to the opening 9c of the outer cover 9 by aligning the notch recess 19a and each hook portion 18a, the upper side of the peripheral wall portion 10b of the inner bolt 10 passes over the upper wall portion 9b of the outer cover 9, thereby providing a click sensation.

[0135] As described above, in the cap unit 1B of this embodiment, by forming a structure in which the inner plug 10 is installed on the outer cover 9 in a way that allows for easy installation and removal, the outer cover 9 and the inner plug 10 can be cleaned separately, and the outer cover 9 and the inner plug 10 can be kept hygienically in contact.

[0136] Therefore, in the capped container 100B equipped with such a capping unit 1B, the ease of use can be further improved.

[0137] (Third Implementation)

[0138] Next, as a third embodiment of the present invention, for example, a device having... Figures 18-22 The capped container 100C of the capped unit 1C shown will be described.

[0139] also, Figure 18 This is a perspective view showing the appearance of the cap unit 1C. Figure 19 This is a vertical sectional view showing the structure of cap unit 1C. Figure 20 This is a perspective view of the cap unit 1C obtained from the bottom side. Figure 21 This is a perspective view showing the state in which the inner bolt 10 has been removed from the outer cover 9 of the cap unit 1C. Figure 22 This is a perspective view showing the structure of the outer cover 9 of the cap unit 1C. Furthermore, in the following description, parts equivalent to those in the cap unit 1A described above will be omitted from the description and will be labeled with the same reference numerals in the accompanying drawings.

[0140] In this embodiment, the cap unit 1C is installed on the container body 2 (not shown) in a way that allows for easy assembly and disassembly to form a capped container 100C.

[0141] Specifically, such as Figures 18-22 As shown, the cap unit 1C has a disassembly and assembly mechanism 11C that allows the inner bolt 10 to be installed and removed from the outer cover 9 in a way that replaces the disassembly and assembly mechanism 11A.

[0142] The disassembly and assembly mechanism 11C includes: a locking part 21, which is provided on either the outer cover 9 or the inner bolt 10 (in this embodiment, the inner bolt 10); and a locked part 22, which is provided on the other (in this embodiment, the outer cover 9).

[0143] The locking portion 21 has a plurality of plungers 21a (two in this embodiment) disposed on the lower side of the flange portion 10d of the inner plug 10. The two plungers 21a are disposed on the lower side of the flange portion 10d of the inner plug 10, facing each other on the back side of the inner plug 10. Each plunger 21a has a structure in which a ball (or pin) disposed on its outer front end is pressed inward against the force of the spring by a spring disposed on its inner side. Each plunger 21a is installed with the ball (or pin) protruding outward from the lower side of the flange portion 10d of the inner plug 10.

[0144] On the other hand, the locking part 22 is composed of an upper wall part 9b provided around the opening 9c of the outer cover 9.

[0145] In addition, the disassembly and assembly mechanism 11C has a positioning engagement part 25, which becomes an anti-rotation part of the inner bolt 10 relative to the outer cover 9 by engaging with the first engagement part 23 provided on the inner bolt 10 and the second engagement part 24 provided on the outer cover 9.

[0146] The first engaging portion 23 is composed of a pair of ribs, which are positioned opposite each other on the underside of the flange portion 10d of the inner bolt 10 and protrude outward from the peripheral wall portion 10b of the inner bolt 10 in a position orthogonal to the plunger 21a when viewed from above.

[0147] On the other hand, the second engaging portion 24 is composed of a pair of grooves, which are formed by radially cutting off the upper wall portion 9b surrounding the opening 9c at a position opposite to the opening 9c of the outer cover 9.

[0148] In the disassembly and assembly mechanism 11C, the first engaging portion 23 and the second engaging portion 24 are aligned to insert the inner bolt 10 from above relative to the opening 9c of the outer cover 9. Thus, the first engaging portion 23 and the second engaging portion 24 engage, and the flange portion 10d of the inner bolt 10 abuts against the upper wall portion 9b surrounding the opening 9c of the outer cover 9, thereby securing the inner bolt 10 to the outer cover 9.

[0149] At this time, each plunger 21a is engaged with the upper wall portion 9b surrounding the opening 9c of the outer cover 9, thereby locking the locking portion 21 with the locked portion 22. Thus, the inner bolt 10 can be installed on the outer cover 9.

[0150] In addition, in the disassembly and assembly mechanism 11C, a click sensation can be provided when each plunger 21a passes over the upper wall portion 9b.

[0151] Furthermore, in the disassembly and assembly mechanism 11C, the cap body 8 (cap unit 1C) is installed on the container body 2 by the engagement of the external thread 14 of the inner bolt 10 with the internal thread 6 of the container body 2. At this time, the flange portion 10d of the inner bolt 10 presses against the upper wall portion 9b of the outer cover 9 from the upper surface side. As a result, the vertical shaking of the outer cover 9 can be suppressed, and the container body 2 can be reliably sealed.

[0152] Furthermore, the outer cover 9 and the inner plug 10 rotate as a unit by engaging the first engaging portion 23 and the second engaging portion 24 of the positioning engaging portion 25. Therefore, the cap body 8 can be installed on the container body 2 by holding the outer cover 9 and rotating it.

[0153] Furthermore, when removing the cap body 8 (cap unit 1C) from the container body 2, the rotation direction is simply reversed, just as during installation. That is, by holding the outer cover 9 of the cap body 8 and rotating it relative to the container body 2 in the opposite direction to the installation direction, the outer cover 9 and the inner plug 10 rotate as a unit. Thus, the cap body 8 can be removed from the container body 2.

[0154] On the other hand, in the disassembly and assembly mechanism 11C, by performing an action opposite to the above-mentioned action, that is, by releasing the locking state of each plunger 21a (locking part 21) relative to the locked part 22, the inner plug 10 is pulled upward from the opening 9c of the outer cover 9, thereby removing the inner plug 10 from the outer cover 9.

[0155] That is, the ability to remove the inner plug 10 from the outer cover 9 is limited to the state where the cap body 8 has been removed from the container body 2. In other words, with the cap body 8 installed on the container body 2, it is impossible to pull the inner plug 10 upwards or pull the outer cover 9 downwards. Therefore, with the cap body 8 installed on the container body 2, the inner plug 10 will not be accidentally removed from the outer cover 9.

[0156] As described above, in the cap unit 1C of this embodiment, by forming a structure in which the inner plug 10 is installed on the outer cover 9 in a way that allows for easy installation and removal, the outer cover 9 and the inner plug 10 can be cleaned separately, and the outer cover 9 and the inner plug 10 can be kept hygienically in contact.

[0157] Therefore, in a capped container 100C equipped with such a capping unit 1C, the ease of use can be further improved.

[0158] (Fourth Implementation)

[0159] Next, as a fourth embodiment of the present invention, for example, a device having... Figures 23-25 The capped container 100D of the capped unit 1D shown will be described.

[0160] also, Figure 23 This is a three-dimensional view showing the appearance of the cap unit 1D. Figure 24 This is a vertical sectional view showing the structure of the cap unit 1D. Figure 25 This is a perspective view showing the state in which the inner bolt 10 has been removed from the outer cover 9 of the cap unit 1D. Furthermore, in the following description, parts equivalent to those in the cap unit 1A described above will be omitted from the description and will be labeled with the same reference numerals in the accompanying drawings.

[0161] In this embodiment, the cap unit 1D is installed on the container body 2 (not shown) in a detachable manner to form a capped container 100D.

[0162] Specifically, such as Figures 23-25 As shown, the cap unit 1D has a disassembly and assembly mechanism 11D that allows the inner bolt 10 to be installed and removed from the outer cover 9 in a way that replaces the aforementioned disassembly and assembly mechanism 11A.

[0163] The disassembly and assembly mechanism 11D includes: a locking part 26, which is provided on either the outer cover 9 or the inner bolt 10 (the outer cover 9 in this embodiment); and a locked part 27, which is provided on the other (the inner bolt 10 in this embodiment).

[0164] The locking portion 26 has a locking protrusion 26a, which is disposed around the opening 9c of the outer cover 9, excluding the first engaging portion 28 described later. The locking protrusion 26a is configured to protrude inward from the upper wall portion 9b disposed around the opening 9c of the outer cover 9 in the horizontal direction.

[0165] On the other hand, the locking portion 27 has a locking recess 27a, which is provided all around the circumference of the inner side of the lower surface of the flange portion 10d, which forms the outer periphery of the inner bolt 10. The locking recess 27a is configured to be provided all around the circumference in correspondence with the locking protrusion 26a, such that the inner side of the lower surface of the flange portion 10d is recessed inward.

[0166] In addition, the disassembly and assembly mechanism 11D has a positioning engagement part 30, which becomes an anti-rotation part of the inner bolt 10 relative to the outer cover 9 by engaging with the first engagement part 28 provided on the outer cover 9 and the second engagement part 29 provided on the inner bolt 10.

[0167] The first engaging portion 28 has a plurality of (two in this embodiment) locking protrusions 28a disposed around the opening 9c of the outer cover 9. The two locking protrusions 28a are positioned opposite each other across the opening 9c of the outer cover 9 and are configured to protrude inward from between a pair of grooves 28b formed by radially cutting off the upper wall portion 9b disposed around the opening 9c.

[0168] On the other hand, the second engaging portion 29 has a plurality of (two in this embodiment) locking recesses 29a disposed on the lower side of the flange portion 10d of the inner bolt 10. The two locking recesses 29a are disposed on the lower side of the flange portion 10d of the inner bolt 10, facing each other on the back side of the inner bolt 10. Each locking recess 29a is configured to cut off a portion of the lower peripheral side of the flange portion 10d corresponding to the locking protrusion 28a.

[0169] In the disassembly / removal mechanism 11D, the first engaging portion 28 and the second engaging portion 29 are aligned to insert the inner bolt 10 from above relative to the opening 9c of the outer cover 9. As a result, the first engaging portion 28 engages with the second engaging portion 29, and the locking protrusion 26a is locked into the locking recess 27a by the elastic deformation (flexion) of the outer cover 9. Thus, the locking portion 26 is locked into the locked portion 27a while the flange portion 10d of the inner bolt 10 abuts against the periphery of the opening 9c of the outer cover 9. Therefore, the inner bolt 10 can be installed on the outer cover 9.

[0170] That is, the locking part 27 and the locking part 26 in the disassembly and assembly mechanism 11D are locked based on the elastic deformation (flexure) of the outer cover 9. The outer cover 9 and the inner bolt 10 are integrated by the relatively weak locking of the locking part 27 provided in the inner bolt 10 and the locking part 26 provided in the outer cover 9.

[0171] Furthermore, in the disassembly and assembly mechanism 11D, when each locking protrusion 26a (locking portion 26) is locked in each locking recess 27a (locked portion 27), a click sensation can be provided.

[0172] Furthermore, the cap body 8 (cap unit 1D) is installed on the container body 2 by screwing the external thread 14 of the inner plug 10 into the internal thread 6 of the container body 2. At this time, the flange 10d of the inner plug 10 presses against the upper wall 9b of the outer cover 9 from the upper surface side. As a result, the vertical shaking of the outer cover 9 can be suppressed, and the container body 2 can be reliably sealed.

[0173] Furthermore, the outer cover 9 and the inner plug 10 rotate as a unit by engaging the first engaging portion 28 and the second engaging portion 29 of the positioning engaging portion 30. Therefore, the cap body 8 can be installed on the container body 2 by holding the outer cover 9 and rotating it.

[0174] Furthermore, when removing the cap body 8 (cap unit 1D) from the container body 2, the rotation direction is simply reversed, just as during installation. That is, by holding the outer cover 9 of the cap body 8 and rotating it relative to the container body 2 in the opposite direction to the installation direction, the outer cover 9 and the inner plug 10 rotate as a unit. Thus, the cap body 8 can be removed from the container body 2.

[0175] On the other hand, in the disassembly and assembly mechanism 11D, by performing an action opposite to the above-mentioned action, that is, by releasing the locking state of each locking protrusion 26a (locking part 26) relative to each locking recess 27a (locked part 27), the inner bolt 10 is pulled upward from the opening 9c of the outer cover 9, thereby allowing the inner bolt 10 to be removed from the outer cover 9.

[0176] As described above, in the cap unit 1D of this embodiment, by forming a structure in which the inner plug 10 is installed on the outer cover 9 in a way that allows for easy installation and removal, the outer cover 9 and the inner plug 10 can be cleaned separately, and the outer cover 9 and the inner plug 10 can be kept hygienically in contact.

[0177] Therefore, in a capped container 100D with such a capping unit 1D, the ease of use can be further improved.

[0178] (Fifth Implementation)

[0179] Next, as a fifth embodiment of the present invention, for example, a device having... Figures 26-28 The capped container 100E of the capped unit 1E shown will be described.

[0180] also, Figure 26 This is a perspective view showing the state in which the inner bolt 10 has been removed from the outer cover 9 of the cap unit 1E. Figure 27 This is a perspective view showing the structure of the outer cover 9 of the cap unit 1E. Figure 28 This is a perspective view showing the structure of the inner bolt 10 included in the cap unit 1E. Furthermore, in the following description, parts equivalent to those in the cap units 1A, 1B, and 1C described above are omitted from the description and are marked with the same reference numerals in the accompanying drawings.

[0181] In this embodiment, the cap unit 1E is installed on the container body 2 (not shown) in a way that allows for easy assembly and disassembly to form a capped container 100E.

[0182] Specifically, such as Figures 26-28 As shown, the cap unit 1E has a disassembly and assembly mechanism 11E that allows the inner bolt 10 to be installed and removed from the outer cover 9 in a way that replaces the aforementioned disassembly and assembly mechanism 11A.

[0183] The disassembly and assembly mechanism 11E combines the structures of the disassembly and assembly mechanisms 11B and 11C described above, and includes: a plurality of hook portions 18a (two in this embodiment) serving as locking portions 18 provided on either the outer cover 9 or the inner bolt 10 (in this embodiment, the inner bolt 10); a plurality of cut recesses 19a serving as locking portions 19 provided on either the other (outer cover 9 in this embodiment); a plurality of plungers 21a serving as locking portions 21 provided on either the outer cover 9 or the inner bolt 10 (in this embodiment, the inner bolt 10); and a plurality of locking recesses 22a serving as locking portions 22 provided on either the other (outer cover 9 in this embodiment).

[0184] The two hook portions 18a and the two plungers 21a are respectively opposite to each other on the peripheral wall portion 10b of the inner plug 10, and are positioned orthogonally to each other when viewed from above. On the other hand, the two notched recesses 19a and the two locking recesses 22a are respectively opposite to each other across the opening portion 9c of the outer cover 9, and are positioned orthogonally to each other when viewed from above.

[0185] Each locking recess 22a is disposed between a pair of locking protrusions 22b, which protrude downward from the lower inner circumferential surface of the upper wall portion 9b disposed around the opening 9c of the outer cover 9.

[0186] In the disassembly and assembly mechanism 11E, the inner bolt 10 is inserted from above relative to the opening 9c of the outer cover 9 by aligning the cut recesses 19a and the hooks 18a. Thus, the hooks 18a are inserted inside the cut recesses 19a, the plungers 21a are inserted inside the locking recesses 22a, and the flange 10d of the inner bolt 10 abuts against the upper wall 9b surrounding the opening 9c of the outer cover 9, thereby locking the inner bolt 10 onto the outer cover 9.

[0187] Here, when each plunger 21a is inserted into the inner side of the locking recess 22a, each plunger 21a passes over the inner peripheral end of the upper wall portion 9b of the outer cover 9, thereby engaging the inner bolt 10 with the outer cover 9 in the vertical direction. That is, when the inner bolt 10 is pulled out from the outer cover 9 upwards, each plunger 21a needs to pass over the inner peripheral end of the upper wall portion 9b of the outer cover 9 again. Therefore, the locking portion 21 and the locked portion 22 also function as a temporary fixing mechanism in the vertical direction.

[0188] Furthermore, when each plunger 21a is inserted into the inside of the locking recess 22a, each plunger 21a passes over the inner peripheral end of the upper wall portion 9b of the outer cover 9, thereby providing a click sensation.

[0189] From this state, by rotating the inner bolt 10 relative to the outer cover 9 to one side about the axis, thereby... Figures 9-12In the installation position shown, each hook 18a is engaged with the periphery of each notch recess 19a. At this time, each plunger 21a passes over the locking protrusion 22b and engages with the upper wall portion 9b provided around the opening 9c of the outer cover 9. Thus, the inner bolt 10 can be installed on the outer cover 9.

[0190] Furthermore, the same applies when the cap body 8 (cap unit 1E) is installed on the container body 2 by screwing the external thread 14 of the inner plug 10 into the internal thread 6 of the container body 2. That is, if the outer cap 9 of the cap body 8 is held and rotated relative to the container body 2, the upper wall 9b abuts against the vertical rib 20b, thereby locking the locking part 18 into the locked part 19, and the outer cap 9 rotates integrally with the inner plug 10. Therefore, even assuming that the outer cap 9 remains in the removed position relative to the inner plug 10, rotating the outer cap 9 naturally creates an installation position, and the cap body 8 can be directly installed on the container body 2 through a series of rotational actions.

[0191] Furthermore, the cap body 8 (cap unit 1E) is installed on the container body 2 by screwing the external thread 14 of the inner plug 10 into the internal thread 6 of the container body 2. At this time, the flange 10d of the inner plug 10 presses against the upper wall 9b of the outer cap 9 from the upper surface side. As a result, the vertical shaking of the outer cap 9 can be suppressed, and the container body 2 can be reliably sealed.

[0192] Furthermore, in the disassembly and assembly mechanism 11E of this embodiment, not only can the inner bolt 10 be rotated relative to the outer cover 9 to one side around the axis, but by rotating it to the other side around the axis, the locking part 18 can also be locked relative to the locked part 19.

[0193] Furthermore, when removing the cap body 8 (cap unit 1E) from the container body 2, the rotation direction is simply reversed, just as during installation. That is, by holding the outer cover 9 of the cap body 8 and rotating it relative to the container body 2 in the opposite direction to the installation direction, the upper wall portion 9b abuts against the vertical rib wall 20b from the side opposite to the installation direction. At this time, the locking portion 18 is locked in the locking portion 19, and the outer cover 9 and the inner plug 10 rotate as a unit. Thus, the cap body 8 can be removed from the container body 2.

[0194] In the disassembly and assembly mechanism 11E, by rotating the inner bolt 10 from its disassembled position relative to the outer cover 9 to one side or the other around the central axis, the locking part 18 can be locked into the locking part 19. That is, when the inner bolt 10 is rotated relative to the outer cover 9, it can rotate in the order of installation position, disassembled position, and installation position, with the disassembled position located between the two installation positions on one side or the other side.

[0195] When the cap body 8 is installed on or removed from the container body 2, the outer cap 9 and inner plug 10 are always in the installation position and rotate as a unit. Therefore, unless the user consciously chooses the removal position, the position of the outer cap 9 and inner plug 10 during normal use is the installation position. Thus, the inner plug 10 can be kept installed on the outer cap 9 without the user consciously choosing the installation position, which is convenient.

[0196] Furthermore, in the disassembly and assembly mechanism 11E, when each plunger 21a rotates between the two installation positions and the disassembly position, a click sensation can be provided by passing over the locking protrusion 22b.

[0197] On the other hand, in the disassembly and assembly mechanism 11E, the locking state of the locking part 18 relative to the locked part 19 is released by rotating the inner bolt 10 relative to the outer cover 9 in such a way that the removal position is located between two installation positions on one side and the other side, and the inner bolt 10 is rotated relative to the outer cover 9 from the installation position to the removal position.

[0198] At this point, the recessed parts 19a and the hook parts 18a are aligned, allowing the inner bolt 10 to be pulled upwards from the opening 9c of the outer cover 9. Thus, the inner bolt 10 can be removed from the outer cover 9.

[0199] That is, the ability to remove the inner plug 10 from the outer cover 9 is limited to the state where the cap body 8 has been removed from the container body 2. In other words, with the cap body 8 installed on the container body 2, it is impossible to pull the inner plug 10 upwards or pull the outer cover 9 downwards. Therefore, with the cap body 8 installed on the container body 2, the inner plug 10 will not be accidentally removed from the outer cover 9.

[0200] Furthermore, the alignment of each locking recess 22a with each plunger 21a simply conveys to the user in an easily understandable way that the alignment of each cut recess 19a with each hook portion 18a (in the removed position). That is, assuming that there are no locking portions 19 and 18, each plunger 21a can pass upward over the inner peripheral end of the upper wall portion 9b of the outer cover 9 from any position.

[0201] As described above, in the cap unit 1E of this embodiment, by forming a structure in which the inner plug 10 is installed on the outer cover 9 in a way that allows for easy installation and removal, the outer cover 9 and the inner plug 10 can be cleaned separately, and the outer cover 9 and the inner plug 10 can be kept hygienically in contact.

[0202] Therefore, in a capped container 100E equipped with such a capping unit 1E, the ease of use can be further improved.

[0203] Furthermore, the present invention is not necessarily limited to the above-described embodiments, and various modifications can be made without departing from the spirit of the present invention.

[0204] For example, the cap units 1A to 1E described above are structures in which the inner plug 10 is installed relative to the container body 2 by screwing in a state where it is inserted into the upper opening 2a of the container body 2, but it is not necessarily limited to such a structure. For example, the cap units 1A to 1E described above can also be structures in which the outer cap 9 is installed to the container body 2 by screwing in a state where it covers the upper opening 2a of the container body 2 from the outside.

[0205] In this configuration, instead of the aforementioned internal thread portion 6 and external thread portion 14, the outer cover 9 (cap body 8) can be installed on the container body 2 in a way that allows for easy installation and removal by engaging the external thread portion provided on the outer peripheral surface of the neck 2d with the internal thread portion provided on the inner peripheral surface of the peripheral wall portion 9a that constitutes the outer cover 9.

[0206] Furthermore, the aforementioned capped containers 100A to 100E are structures that directly open and close the upper opening 2a of the container body 2, but are not necessarily limited to such a structure. For example, it is also possible to have capped units 1A to 1E that can be easily installed and removed from the shoulder member installed on the container body 2.

[0207] Furthermore, the structure can also be one in which the lid is installed on the cap body mounted on the container body 2 in a way that allows it to open and close freely. In this case, the lid can be installed on the cap body by screwing, or the lid can be installed on the cap body in a way that allows it to rotate freely via a hinge.

[0208] Furthermore, in the above embodiments, the present invention is exemplified as being applied to a beverage container that has a heat preservation function (or cold preservation function) due to the container body 2 having the above-described vacuum insulation structure. However, the present invention can be widely applied to lidded containers that have a container body and a lid that can be easily attached and detached from the container body.
