Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drinking bottle used as a portable heat-insulating container for tea and coffee.

[0002]

2. Description of the Related Art A drinking bottle as described above is shown in FIG.
As shown in (a), the container body 51 is provided with a bottomed cylindrical container body 51 and a stopper 52 covering an upper end opening of the container body 51. The container body 51 has a vacuum insulation space 55 between the inner container 53 and the outer container 54, each of which is made of a stainless steel plate, as shown in FIG. Is formed.

When drinking a stored liquid 56 such as tea or coffee in the container body 51, the stopper 52 is removed and the container body 51 is removed.
Is used by directly putting a mouth on the upper end of the container, that is, using the container body 51 as a mug. Therefore, such a drinking bottle is a portable insulated container premised on the use of one person, and the soaking bottle has a smaller capacity and a smaller diameter than a so-called stainless steel bottle in which the container body is configured almost similarly to the above. It is formed in a slim shape with a smaller size, and is also used as a stainless steel mini bottle or mug bottle.

[0004] In a stainless steel bottle, a water inlet is provided in a plug body that closes an upper end opening of the container body, and an outer plug that covers the plug body is further provided. Usually, the outer stopper is formed in a cup shape, and after the liquid stored in the container body is poured into the outer stopper, the outer stopper is used with a mouth attached to drink. Therefore, the stopper body of the stainless steel bottle is formed in a double stopper structure including the stopper body described above and an outer stopper formed in a shape that also functions as a mug.

[0005] On the other hand, in a drinking bottle, it is not necessary to provide a component to function as a mug in the stopper.
The shape and the like are determined from the viewpoint of hermeticity, heat retention and miniaturization of the container body 51. For example, the plug 52 shown in FIG. 5B is formed in a double plug structure in which a plug main body 57 that closes the upper end opening of the container main body and a plug cap 58 that is screwed from above and assembled thereto are provided. However, this is because a bottom wall portion 57a provided on the stopper main body 57 and a stopper cap 58 are provided.
Substantially closed space 59 with the top plate portion 58a in FIG.
Is formed, which functions as a heat insulating space that suppresses upward heat radiation from inside the container body 51.
Therefore, the stopper cap 58 is used while being attached to the stopper main body 57, and when the stopper 52 is washed, the stopper cap 58 is removed from the stopper main body 57 and each is washed in a round.

[0006]

However, in the conventional drinking bottle configured as described above, it is presumed that the drinking bottle is carried outdoors and used, but the portability is taken into consideration. It is not always enough. In other words, the conventional drinking bottle is a container body 51
The overall shape of the plug 52 and the plug 52 has no external protrusions, so that the size and size of the plug 52 are reduced. When carrying a drinking bottle having such an external shape, it is possible to carry the outer periphery of the container body 51 by hand for a short time, but for a long time, a carrying bag with a hanging string is provided. There is no other choice but to prepare separately and carry it in it, or carry it in a bag or the like. That is, it is necessary to separately prepare an object capable of accommodating the entire drinking bottle with a portable hanging string or belt, and therefore, sufficient convenience cannot be obtained.

[0007] The present invention has been made in view of the above problems, and an object of the present invention is to provide a drinking bottle that can improve portability and does not impair slimness. .

[0008]

SUMMARY OF THE INVENTION Therefore, a drinking bottle according to claim 1 of the present invention comprises a container main body having an enclosure having a heat retaining function, and a plug body detachably attached to an upper end side of the container main body. A drinking bottle, characterized in that a suspending portion for forming a suspending opening that penetrates in a substantially horizontal direction is provided on an upper end surface of the stopper.

In the drinking bottle thus formed, for example, a fingertip can be inserted into the hanging opening and carried, or the bottle can be put on a shoulder through a string through the hanging opening. Therefore, it is possible to easily carry the bag for a long time without separately providing a bag capable of accommodating the entire drinking bottle provided with a portable hanging string or the like, thereby improving convenience. Further, since the above-mentioned hanging portion is provided on the upper end surface of the plug, the external shape of the side surface of the plug can be the same as the conventional shape, so that overall slimness can be maintained as much as possible. .

[0010] In particular, like the drinking bottle of claim 2,
If the suspending portion is formed so as to be located in a cylindrical region surrounded by extending the outer peripheral surface of the plug body upward, the entire suspending portion including the suspending portion formed on the upper end surface of the stopper body is formed. Slimness is maintained as before.

According to a third aspect of the present invention, in the case where the stopper is formed by providing a stopper body screwed to the upper end side of the container body and a stopper cap screwed to the stopper body from above. In the case of a so-called double stopper structure, the above-mentioned hanging part may be provided on the upper end surface of the stopper cap.

According to a fourth aspect of the present invention, there is provided a drinking bottle according to the second or third aspect, wherein the stopper is provided with a top plate and a bottom wall which are vertically separated from each other. A substantially closed space is formed therebetween, and a concave portion that is recessed downward is provided in the top plate portion, and the hanging portion is formed so as to straddle the concave portion.

According to this structure, in the plug provided with the space between the top plate and the bottom wall, that is, a heat insulating space for suppressing heat radiation upward from the container body, the top plate is recessed in the space direction. By providing the recessed portion to be inserted, the hanging opening can be formed below the hanging portion even when the hanging portion is formed along the upper surface of the top plate portion. Therefore, in this case, it is possible to make the shape of the hanging portion not to protrude upward from the upper surface of the top plate portion, and it is possible to maintain the downsizing in the height direction.

According to a fifth aspect of the present invention, there is provided a drinking bottle according to the second or third aspect, wherein the stopper is provided with a top plate and a bottom wall which are vertically separated from each other. A substantially closed space is formed between the top plate and a concave portion that is recessed downward is provided in the top plate portion. It is characterized in that it is attached to the top plate so as to be tiltable between the stored non-use position.

According to this configuration, when the hanging portion is not used, the hanging portion is turned over and stored in the recess of the top plate portion, so that the hanging portion can be prevented from protruding upward. Therefore, in this state, since the appearance is the same as that of the related art, even when the portable device is carried in a bag or the like, this can be performed as usual without causing any particular trouble.

According to a sixth aspect of the present invention, there is provided a drinking bottle according to the second or third aspect, wherein a stopper is screwed onto an upper end side of the container body to have a bottom wall for closing an upper end opening of the container body. And a top plate that is removably assembled to the stopper body and forms a substantially sealed space with the bottom wall. Part, and further provided with an engagement mechanism for mutually engaging the top plate part and the plug body when the top plate part is located at a specific circumferential position with respect to the stopper body, The plug body is formed so as to rotate integrally when a rotational force is applied to the plug body.

In this drinking bottle, since the top plate portion having the hanging hand portion is provided detachably with respect to the stopper main body, the top plate portion and the stopper main body are each washed with a circle, and the bottom wall portion and the ceiling portion are removed. The wall surrounding the space between the plate portion can be maintained in a cleaner state. In addition, in the assembled state in which the top plate is positioned at a specific circumferential position with respect to the stopper body, the stopper can be opened and closed by applying a rotating force to the lifting part. This further improves convenience.

In a seventh aspect of the present invention, there is provided a drinking bottle according to any one of the first to sixth aspects, wherein the stopper is screwed to an upper end side of the container body so as to be in a closed state. It is characterized in that a lock mechanism for preventing relative rotation between the plug and the container body in a closed state is provided between the container and the container body.

According to this configuration, for example, even when the hanging portion is provided in a shape protruding upward from the top plate portion,
The plugged state is reliably maintained. In other words, when the drinking bottle is carried in a bag or the like, another object may hit the hanging portion due to the vibration and a force in the opening direction may be applied, and the stopper may be loosened. Therefore, by setting the lock state by the lock mechanism as described above, such loosening of the plug is prevented.

[0020]

As shown in FIG. 1A, a drinking bottle 1 according to the present embodiment includes a container body 2 having a liquid storage space 2 a formed therein, and a stopper 3 closing an upper end opening of the container body 2. It is provided and configured.

The surrounding wall of the container body 2 surrounding the storage space 2a is formed in a double structure of an inner container 4 and an outer container 5 each made of a stainless steel plate. Inner container 4
Is formed in a bottomed cylindrical shape in which a bowl-shaped inner cylinder bottom plate 4b is continuously connected to the lower end of the thin cylindrical inner cylinder body 4a. The inner cylinder body 4a is provided with a helical female screw 4c for attaching a helical plug formed by bulging inward in the radial direction in a region slightly below the upper end. Below the female screw 4c, a packing receiving portion 4d having a substantially triangular cross section, which is bulged inward in the radial direction in the same manner as described above, is formed in an annular shape. A space below the packing receiving portion 4d is a storage space 2a for storing liquids such as tea, coffee, and soft drinks.

The outer container 5 is formed by butt-welding the upper end of an outer cylinder bottom plate 5b having a substantially U-shaped cross section to the lower end of the outer cylinder body 5a surrounding the inner cylinder body 4a from the outside. It is formed in a shape that surrounds from the outside. At the upper end side of the outer container 5, a shoulder 5c that is bent inward in the radial direction is provided at substantially the same height as the position where the female screw 4c for attaching the plug of the inner container 4 is formed. The upper part of 5c is formed as a cylindrical drinking port 5d slightly smaller in diameter than the lower part. The upper edge of the drinking spout 5d and the upper edge of the inner container 4 are hermetically joined over the entire circumference by welding or the like.

On the other hand, the outer cylinder bottom plate 5b of the outer container 5 is formed in a shape in which the center side is recessed in a step-like shape at the upper side, and has an arc-shaped cross section in which an exhaust hole is formed at the center at the center. A recess 5e is formed. Through the exhaust hole, the assembly between the inner container 4 and the outer container 5 as a vacuum insulation space is performed. In this case, the container body 2 is turned upside down, and a sealing material 7 made of, for example, low-melting glass or the like is placed on the recess 5e.
This is done by sending As a result, the air in the space 6 is sucked out through the exhaust hole, and the exhaust hole is sealed by heating the entirety and melting the sealing material 7 in this state, so that the space 6 becomes a vacuum heat insulating space. It is formed as.

A getter member 8 is fixed on the outer cylinder bottom plate 5b by a mounting member 9. After the space 6 is evacuated and sealed, the outgas generated from the wall surrounding the space 6 is adsorbed by the getter member 8, and the inside of the space 6 is maintained at a desired degree of vacuum. In FIG. 1, reference numeral 10 denotes a fixing member for preventing the sealing member 7 from dropping off, and reference numeral 11 denotes these sealing member 7 and the fixing member 10.
Is a synthetic resin cover sheet adhered to the outer cylinder bottom plate 5b so as to cover the cover.

The plug body 3 is made of a synthetic resin such as polypropylene, for example. The plug body 12 is screwed to the container body 2 to cover the upper end opening of the container body 2, and is assembled to the plug body 12 from above. A plug cap 13 is provided.

As shown in FIG. 2B, the stopper main body 12 has a bottom wall portion 14a having a substantially horizontal disc shape and a bottom wall portion 14a.
A container closing member 14 having a substantially U-shaped cross section having a cylindrical peripheral wall portion 14b extending upward from the peripheral edge of the container a is provided. On the outer surface of the peripheral wall portion 14b, a male screw 14c to be screwed with the female screw 4c for attaching a plug of the container body 2 is formed. The plug cap 1 is provided on the inner surface of the peripheral wall portion 14b.
3 is formed with a female screw 14d for attaching a cap.

At the upper end side of the container closing member 14 having the above-mentioned shape,
The plug main body 12 is formed by welding and integrating the ring-shaped opening / closing operation member 15. The opening / closing operation member 15 is provided with a substantially cylindrical opening / closing operation surface 15a surrounding the outside of the peripheral wall portion 14b, and an inward flange portion 15b directed radially inward from the upper end of the opening / closing operation surface 15a is closed by a container. The opening and closing operation member 15 is fixed to the container closing member 14 by welding to the upper end surface of the peripheral wall portion 14 b of the member 14. As will be described later, when the stopper 3 is attached to the container main body 2 and the stopper is opened or removed, the palm is rolled to open and close the opening / closing operation surface 15a.
This is performed by gripping and rotating the outer periphery of the.

Further, a short cylindrical portion 14e hanging downward is further provided on the outer peripheral side of the bottom wall portion 14a, and a seal packing 16 is mounted on the outer peripheral portion of the cylindrical portion 14e. In addition, the bottom wall portion 14a is provided at the center side thereof.
A plurality of communication holes 14f vertically penetrating through a are provided. Further, a negative pressure prevention valve 17 made of an elastic material and closing the communication holes 14f from below is mounted at the center of the bottom wall portion 14a.

As shown in FIG. 1A, the stopper cap 13 has a substantially cylindrical cylinder 18 having an external thread 18a formed on the outer peripheral surface thereof, and a top plate 19 for closing the upper end opening of the cylinder 18. Are formed. The top plate 19 has its outer peripheral edge fitted into an annular groove formed on the upper end surface of the cylindrical body 18,
In this region, it is welded to and integrated with the cylinder 18. The top plate 19 has an arch-shaped hanging part 2 to be described later.
0 is integrally formed.

In the plug cap 13 having the above-described shape, the cylindrical body 18 is inserted into the peripheral wall portion 14b of the plug main body 12 from above, and the male screw 18a of the cylindrical body 18 is connected to the inner surface of the peripheral wall portion 14b as shown in FIG. And screwed onto the female screw 14d for cap attachment. In the plug body 3 assembled in this manner, a space 21 in which the top and bottom are closed by the top plate portion 19 and the bottom wall portion 14a is formed inside the cylindrical body 18. Thereby, when the plug 3 is assembled to the upper end of the container main body 2, the space 21 functions as a heat insulating space, heat radiation from the container main body 2 upward is suppressed, and excellent heat retention is maintained.

The cylindrical body 18 of the plug cap 13 is further integrally formed with a curved hanging portion 18b on the outer peripheral side of the upper end. The stopper cap 13 is assembled to the stopper body 12 in a state where the lower end of the hanging part 18b is in contact with the upper surface of the inward flange 15b of the opening / closing operation member 15 in the stopper body 12. In this state, the hanging portion 18b is formed so as to have an external shape smoothly connected to the opening / closing operation surface 15a.

The drinking bottle 1 having the above-described structure is provided in the storage space 2a in the container body 2 with hot tea or coffee.
After pouring a desired drink such as black tea, cold and chilled juice, soft drink, etc., the plug 3 is poured as shown in FIG.
By screwing the male screw 14c into the female screw 4c for attaching a plug on the upper end side of the container body 2 and plugging the same, the temperature of the liquid stored inside is kept for a long time.

In the closed state as described above, the seal packing 16 mounted on the lower end of the plug 3 is pressed against the packing receiving portion 4d of the container body 2 from above, and the inside of the storage space 2a is held in a sealed state. Is done. At this time, most of the container closing member 14 of the plug 3 is inserted into the upper end side of the container body 2. Therefore, the heat insulating space 2 between the bottom wall portion 14 a of the container closing member 14 and the top plate portion 19.
Numeral 1 is located above the packing receiving portion 4d of the container body 2 in a region corresponding to a dead space that does not function as a storage space. For this reason, even if the plug 3 provided with the above-described heat insulating space 21 is attached to the container body 2,
The overall height is minimized.

Further, in this closed state, the opening / closing operation surface 15a of the plug 3 comes into contact with or close to the shoulder 5c of the container body 2 from above, so that it is substantially flush with the outer periphery of the container body 2. Is formed. Thereby, even in the closed state, there is no uneven portion on the outer peripheral surface, and the overall appearance is slim.

When drinking the beverage stored in the storage space 2a, the drinking bottle 1 holds the outer periphery of the opening / closing operation surface 15a of the stopper 3 and rotates it to remove the stopper 3 from the container body 2. After that, it is used in a form in which the mouth 5d at the upper end of the container body 2 is directly put into the mouth for drinking. That is, the container body 2 with the stopper 3 removed is used as a mug in which drinking water is poured. Therefore, the outer diameter of the container main body 2 is about 5 to 7 cm so that the outer periphery thereof can be grasped by hand. The height is about 15 to 20 cm, and the content is about 200 to 450 cc.

When hot tea or the like is stored in the storage space 2a, if the pressure in the storage space 2a drops due to the temperature drop over a long period of time, the plug 3 is pulled into the plug body 3. Acts to make opening operation difficult.
Therefore, when such a pressure drop occurs, the periphery of the negative pressure prevention valve 17 is deformed downward. Thus, the storage space 2a communicates with the space 21 above the bottom wall portion 14a through the communication hole 14f. This space 21 communicates with the outside through a screwing gap between the female screw 14d for cap attachment and the male screw 18a. Therefore, the negative pressure prevention valve 17 as described above
Prevents the pressure in the storage space 2a from dropping, and ensures a smooth opening operation.

By the way, such a drinking bottle as described above is conventionally carried in a bag or a bag, and for this purpose, it is formed in a slim shape with an outer diameter dimension as small as possible. However, in this case, it is necessary to secure a storage space in the bag or the bag according to the shape of the drinking bottle, and accordingly, there is a limitation on the amount of other storage items and the storage state.

Therefore, in the drinking bottle 1 according to the present embodiment, as shown in FIG. 1B, a hanging hand portion 20 that protrudes upward in an arch shape is integrally provided on the top plate portion 19 of the plug 3. A suspending opening 20a penetrating in the horizontal direction is formed between the suspending portion 20 and the upper surface of the top plate portion 19.

FIG. 3 shows an example of use of such a hanging part 20. FIG. 2A shows a hanging opening 20 a (hereinafter simply referred to as the hanging hand portion 20) below the hanging portion 20.
(B) is a state in which the belt 22a of the lunch jar 22 is passed through the hanging portion 20 so that the drinking bottle 1 can be carried together with the lunch jar 22. FIG. The state in which the drinking bottle 1 is suspended from the school bag 23 with the clip 24, FIG.
Is a state in which the drinking bottle 1 is hung on a hanging bracket 26 attached to a side of a desk 25 in the classroom, and FIG. 4E is a state in which the drinking bottle 1 is hung by a clip 28 on a golf bag 27; (F) is a state where the drinking bottle 1 is suspended from the buggy 29 by the S hook 30. Further, as shown in FIG. 2G, it is also possible to attach a mobile strap 31 to the hanging portion 20 and hang the drinking bottle 1 via the mobile strap 31.

FIG. 4H shows a state in which the hanging hand portion 20 is used as a knob when the plug 3 is opened by sandwiching the hanging hand portion 20 with a fingertip and applying a rotational force to the hanging hand portion 20. Is shown. That is, the opening and closing of the plug 3 is normally performed by gripping the opening / closing operation surface 15a described above. However, the provision of the above-described hanging portion 20 allows the use of this as an opening / closing operation portion. Is also possible.

As described above with reference to FIG. 2, the stopper 3 is formed in a double stopper structure by providing a stopper main body 12 and a stopper cap 13 which can be separated from each other. Thereby, if the plug cap 13 is removed from the plug main body 12, the wall surface surrounding the heat insulating space 21 is exposed, and this can be easily washed in every corner.

At this time, the stopper cap 13 is attached to the stopper body 12.
Also has a screw tightening structure in the same manner as the attachment of the plug body 12 to the container body 2. These two screw tightening structures are formed so that the lead angles are different from each other so that the stopper body 12 can be removed from the container body 2 with a smaller force. However, when the capping operation is to be performed by applying a rotational force to the hanging hand portion 20 as described above, only the cap 13 is rotated, and the plug body 12 may not rotate in the capping direction. You. Therefore, for example, if the screw fastening structure between the stopper body 12 and the container body 2 is formed with a right-hand screw, and the screw fastening structure between the stopper cap 13 and the stopper body 12 is formed with a left-hand screw, the lifting hand portion 20 is formed. Even with the used operation, the stopper can be reliably opened.

As described above, the drinking bottle 1 according to the present embodiment is configured such that the hanging part 2 is attached to the top plate 19 of the stopper 3.
0 is provided integrally. Therefore, in the related art, the portable device can be carried only in a bag or the like, but can be carried in various forms by using the above-mentioned hanging portion 20, so that the convenience is greatly improved.

The above-mentioned hanging part 20 is provided on the top plate part 19 of the plug 3. That is, in the case of the stainless steel bottle described above, it is assumed that the outer stopper can be used as a mug. Therefore, it is necessary that the upper surface be flat so that the outer plug does not fall when placed on a table upside down.

On the other hand, in the case of a drinking bottle, there is no restriction on the shape of the stopper cap 13 corresponding to the outer stopper described above, and therefore, the hanging part 20 projects upward to the top plate part 19. It can be provided in a shape. As a result, the hanging portion 20 is located in the cylindrical region surrounded by extending the outer peripheral surface of the plug 3 upward, and thus has a shape without any lateral irregularities. Slimness is maintained. As a result, for example, even in the case of carrying in a bag or the like as in the related art, it is possible to easily store or take out the bag.

[Second Embodiment] Next, another embodiment of the present invention will be described. For the sake of convenience, members having the same functions as those described in the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted. The same applies to other embodiments described later.

In the drinking bottle 1 according to the present embodiment, as shown in FIGS. 4A and 4B, a concave portion 19a is formed by depressing a central region of the top plate portion 19 downward. The hanging portion 20 has a shape continuous with the upper surface of the top plate portion 19 in a plane, that is, a substantially horizontal shape that curves slightly upward from the upper edge of the concave portion 19a, and has a shape that straddles the concave portion 19a. Is provided.

Therefore, in the drinking bottle 1, by providing the recess 19 a as described above, a part of the heat insulating space 21 formed between the plug cap 13 and the plug body 12 in the above-described embodiment can be used as a hanging handle. This configuration is used as an insertion space for a fingertip or the like below the part 20. For this reason,
Even when the hanging portion 20 is provided on the top plate portion 19, the hanging portion 20 does not protrude upward, and the overall height dimension can be made more compact as before. It is possible.

[Embodiment 3] FIG. 5 shows a drinking bottle 1 according to still another embodiment of the present invention.
In this drinking bottle 1, as shown in FIG.
The hanging portion 20 is separate from the top plate portion 19 and formed in a semicircular arc shape. The top plate portion 19 is provided with a concave portion 19b having a shape corresponding to the hanging portion 20, that is, a substantially crescent-shaped concave portion 19b in plan view when viewed from above. The hanging part 20 is pivotally attached to the top plate part 19 at both lower ends thereof so as to be tiltable.

In the drinking bottle 1 of this configuration,
When the suspender 20 is used, as shown in FIG. 2A, the suspender 20 is set upright, and a fingertip or the like is inserted into the suspender 20 and carried as described above. be able to. On the other hand, when the suspender 20 is not used, the suspender 20 is stored in the recess 19b by turning the suspender 20 sideways as shown in FIG. It is almost flat. Therefore, in this case, the overall height is reduced as in the second embodiment, and the device is more compact.

[Embodiment 4] FIG. 6A shows an external shape of a plug 3 according to still another embodiment of the present invention. The plug 3 includes a top plate 19, a compression coil spring 32, and a plug main body 12 shown in FIG.
The top plate portion 19 is formed in a substantially disk shape, and an arch-shaped hanging portion 20 is provided on the upper surface thereof as in the first embodiment. In addition, at two points symmetrical about the center point on the peripheral side,
A substantially rectangular locking projection 19c, each projecting radially outward.
19c are formed. These locking projections 19c and 19
“c” has a thickness smaller than that of the inside, and is provided in a step shape with respect to the upper surface of the top plate portion 19.

The plug body 12 is, as shown in FIG.
It comprises a container closing member 14 formed substantially in the same manner as in the first embodiment described with reference to FIG. 2, and an opening / closing operation member 15 welded and integrated with this. However, in the present embodiment, the opening / closing operation surface 15a of the opening / closing operation member 15 extends upward and inward, and the opening / closing operation member 15 is integrally formed with an upper wall portion 15c that forms the outer peripheral side of the upper end surface of the plug 3. Is formed.

As shown in FIG. 3B, a circular opening 15d into which the top plate 19 is fitted is formed in the upper wall 15c. The top plate 1 is provided on the peripheral surface of the circular opening 15d.
9 are respectively formed at two locations corresponding to the locking projections 19c and 19c, respectively. Further, locking concave portions 15f are formed at two centrally symmetric locations 90 degrees apart from each other in the circumferential direction from the positions where the extracting concave portions 15e are formed.
These locking recesses 15f are shaped so as to be recessed upward in a rectangular cross section from the lower surface of the upper wall portion 15c. In order to restrict the relative rotational movement in the circumferential direction, it is formed with a circumferential width dimension corresponding to each locking projection 19c.

A top plate 19 is attached to the plug body 12 having the above-described shape, as shown in FIG. That is,
In this assembled state, the locking projections 19c / 1 of the top plate 19 are
9c are fitted into the locking recesses 15f from below, and each of the locking projections 19c is formed by the compression coil spring 32 compressed between the top plate 19 and the bottom wall 14a of the plug body 12.
19c is pressed and held against the upper wall 15c from below. At this time, the top plate 19 and the upper wall 15
Each upper surface of c is formed so as to be flush.

In this state, the relative rotation between the top plate 19 and the plug body 12 is restricted by the engagement mechanism between the locking projection 19c and the locking recess 15f into which the locking projection 19c is fitted. For this reason, if a rotational force is applied to the hanging portion 20, the rotating force is transmitted to the plug body 12 as it is, and therefore, instead of the operation of gripping and rotating the opening / closing operation surface 15a, the hanging portion 20 is used. Each operation of opening and closing can be reliably performed.

On the other hand, from the above state, the top plate 19 is pushed down against the spring force of the compression coil spring 32, and is lowered until the locking projections 19c are disengaged downward from the locking recesses 15f. For example, the top plate 19 can be relatively rotated with respect to the plug main body 12. Therefore, each locking projection 1
When the pressing force is released by rotating 90 degrees from the above until the positions of the concave portions 9c and 19c correspond to the concave portions for extraction 15e, the top plate portion 19 is pushed upward by the compression coil spring 32. At this time, each locking projection 19c
c moves upward through the extraction concave portion 15e, whereby the top plate portion 19 can be pulled upward from the plug main body 12, as shown in FIG.

As described above, in the present embodiment, the plug opening / closing is performed by using the suspender 20 provided on the top plate 19.
It is possible to reliably perform the plugging operation, and remove the top plate portion 19 covering the upper part from the plug main body 12 so as to form a substantially sealed space 21 in the plug main body 12, and make the upper part of the space 21 larger. It is also possible to expose. Therefore, by disassembling in this manner, each inner wall surface surrounding the space 21 can be washed to every corner and maintained in a cleaner state.

[Fifth Embodiment] A drinking bottle 1 according to a further embodiment shown in FIG. 7A is further provided with a lock mechanism 33 between the stopper 3 and the container body 2. Other configurations are the same as those of the first embodiment. The lock mechanism 33 is for holding the plug 3 screwed to the container main body 2 and tightened, that is, a closed state.

That is, when the hanging portion 20 is provided on the top plate portion 19 so as to protrude upward, as described with reference to FIG.
Can also be used as an operation unit at the time of opening. When the opening / closing operation surface 15a on the lower end side of the plug body 3 is gripped by the palm to perform the opening operation, it is necessary to appropriately apply the axial force to the fingertip together with the circumferential rotational force. By preventing the fingertip from slipping in the circumferential direction by the frictional force generated by this, the stopper 3 can be rotated and opened. On the other hand, in the case of opening the hanging part 20 with a fingertip, it is only necessary to apply a rotational force. This is because, for example, when the drinking bottle 1 is carried in a bag or the like and another object repeatedly hits the hanging portion 20 and a force in the opening direction acts, the plug 3 is loosened. There is a risk that the plugged state will be impaired.

Therefore, in the present embodiment, the lock mechanism 33 as described above is provided, so that even if the user does not intend to perform the opening operation, even if an external impact or vibration is applied to the hanging portion 20 from outside. Thus, the closed state is reliably maintained. Such a lock mechanism 33 is configured as follows in the present embodiment, for example.

That is, as shown in FIGS. 7B and 7C, the lock mechanism 33 is formed so that the outer surface of the opening / closing operation surface 15a of the plug main body 12 is partially bulged outward. 34, and a plate guide groove 34 extending in the longitudinal direction at the center of the lock plate mounting portion 34.

a is slidably assembled vertically.

On the other hand, a lock plate receiving member 38 is fixed to the container body 2 by spot welding or the like. The metal fitting 38 is provided at a circumferential position corresponding to the lower side of the lock plate 35 in a closed state in which the plug 3 is screwed to the container body 2 and tightened. Therefore, in this state, the lock plate 35 is moved to the lower limit position (the position shown).
By lowering the lock plate 35, the lower end of the lock plate 35 is inserted into the lock plate receiving member 38 to be in a locked state. Thereby, even if a force in the opening direction acts on the plug 3 at a time other than the opening operation intended by the user,
The relative rotational movement of the plug 3 and the container body 2 is prevented,
The plug 3 is prevented from rotating and loosening in the opening direction.

The locked state can be released by operating the projection 36.
This operation is performed by placing a fingertip on the device and sliding the operation protrusion 36 upward. As shown in FIG. 3C, the operation protrusion 36 is provided on the side wall of the plate guide groove 34a.
An arcuate locking portion 34b is formed in accordance with the outer peripheral shape. By raising the operation protrusion 36 to the position of the arcuate portion locking portion 34b and fitting it, the operation protrusion 36 is held at this position. In this state, the lower end of the lock plate 35 comes out of the lock plate receiving fitting 38, and the lock is released. Accordingly, in this state, the opening operation is performed by putting a hand on the opening / closing operation surface 15a or the hanging hand portion 20 as described above.
