The container port plug can have the mouth of the container in the axial direction because it has a bolt cover from the axial cover to the outer circumference of the container and a plug which is recessed from the axial direction of the bolt cover. The upper portion is inserted into a gap formed between the inner circumference of the cap and the outer circumference of the middle pin. If the beverage is poured from the mouth of the container, or the lips are placed close to the outer peripheral feeding of the container, the beverage will adhere to the inner or outer circumference of the mouth of the container. The beverage may be attached to the inner circumference of the cap or the outer circumference of the middle peg in the aforementioned gap. Considering the heat insulating property, the gap between the inner circumference of the cap and the outer circumference of the middle plug is preferably as small as possible, and the width thereof is narrow.

However, there is a problem that it is difficult to clean the beverage adhering to the gap.

Further, when the container port plug is cleaned, the tampon is washed and removed from the middle. In order to facilitate the removal of the stuffing member, a stuffing member support portion is provided on the outer circumference of the bolt in the axial projection, and the stuffing member is embedded therein.

However, if the stuffing member support portion is provided so that the self-plugging cover protrudes in the axial direction, the packing member can be placed in the axial direction of the container at the sealing position of the sealing surface on the inner circumference of the container. Since this will reduce the capacity of the container in the axial direction, there is a problem that it becomes an obstacle to miniaturization of the container.

Therefore, an object of the present invention is to reduce the size of the container while maintaining the cleanliness in the gap between the inner circumference of the cap and the outer circumference of the middle plug.

In order to solve the above problems, the container port plug of the present invention is configured to have a threaded portion that is detachably screwed from the container, a cap cover from the axial cap to the container, and a middle pin that is recessed from the cap in the axial direction. a plug body, and a buckle cap covering the middle plug freely; and the middle plug has a stuffing member embedded on an outer circumference thereof, and the plug body is fixed on the container by the thread portion In the state, the aforementioned stuffing member is stored in the aforementioned container Between the inner circumference and the outer circumference of the middle bolt; the threaded portion is disposed on the inner circumference of the bolt cover, and the packing member is embedded in the outer circumference of the middle bolt, and is embedded in the radial direction of the screw portion. In the tampon support portion provided, the middle yoke and the tying cover are detachably fastened to a portion of the tampon support portion on the side of the axial ferrule cover. In addition, "axial direction" means the direction along the axis of the threaded portion. The circumference around the center of the surrounding axial direction is referred to as "inner circumference" in the vicinity of the same axial position in the double center, and the outer side is referred to as "outer circumference".

If the threaded portion of the container mouth plug is disposed on the inner circumference of the bolt cover, it is not necessary to provide a threaded portion on the outer circumference of the middle bolt as in the object of Patent Document 1, and the thread can be threaded radially from the thread in the outer circumference of the middle bolt. A tampon support portion is provided at a portion of the portion. Thereby, since the sealing position of the stuffing member can be brought close to the side of the cap, the capacity can be ensured to be large in the axial direction in the container. Even if the same capacity is ensured, the container can be miniaturized.

Since the middle bolt and the bolt cover can be buckled freely on the side of the axial plug cap side than the stuffer support portion, when the inner circumference of the sweep bolt cover and the outer circumference of the middle bolt are in the gap The middle bolt can be removed from the bolt cover to make the cleaning property good. Further, since the tamping member can be fastened or detached from the tamping support portion in a state in which the middle yoke is removed, even if the tampon support portion is provided in the outer circumference of the middle yoke from the thread portion facing the thread portion in the radial direction, There is no need to worry about the difficulty of the detachment of the stuffing.

For example, the middle pin may have a locking claw that protrudes toward the axial cap surface on the inner and outer circumferences of the plurality of portions in the circumferential direction, and the cap has a claw receiving portion that is engaged with the locking claw. By causing the latching claws of the middle latches to be axially contacted and elastically inclined with respect to the claw receiving portion, and elastically retracting beyond the claw receiving portions, and reaching positions that are axially engaged with each other; the cap cap In the state of being attached to the plug body, the inclination of the claw is restricted to a range in which the claw receiving portion cannot be removed.

As the structure for releasing the middle bolt and the bolt cover freely, the aforementioned claw and claw receiving portion can be employed. The buckle type cap can be disposed in such a manner that the inclination of the pawl is restricted to a range in which it cannot be released from the claw receiving portion in a state of being attached to the plug body. In the above manner, even if the middle latch is forcibly tilted with respect to the axial direction toward the side corresponding to the tilting direction of the latching claw, the latch cap can be prevented from coming out of the claw receiving portion by the cap cap.

Preferably, the cap cap has a tubular portion that is inserted into the inner side of the inner circumference of the middle pin, and a cap packing that is fitted to the outer periphery of the tubular portion, and is detachably covered by the middle plug. The cap cap and the middle plug of the recessed space form a heat insulating chamber, and the cap packing seals between the inner circumference of the middle plug and the outer circumference of the tubular portion, and the cylindrical portion restricts the inclination of the locking claw.

Since the cap cap that freely covers the recessed space of the middle plug has a tubular portion inserted into the inner side of the inner periphery of the middle plug, the heat insulating chamber can be formed by the cap cap and the middle plug. If the inner circumference of the middle plug and the outer circumference of the tubular portion are sealed by the cap filling member embedded in the outer circumference of the tubular portion, the inner circumference of the middle plug is protruded to the axial cap surface by the tubular portion. The inclination of the claws does not require the beverage to be immersed in the heat insulation chamber. Since the inclination of the detent pawl can be restricted by the cylindrical portion for forming the heat insulating chamber, it is not necessary to add a wall for the tilt restricting to the cap cap.

According to the container mouth plug of the present invention, for example, the beverage container may be configured as follows: the container includes a double insulated container in which the inner container and the outer container are joined, and the smallest inner diameter portion of the inner container is present in the outer a portion above the shoulder of the container near the side of the axial cap cap, the outer container having a thread that is screwed into the threaded portion, and in a state where the plug body is fixed to the container, the cap is by the foregoing The shoulder of the outer container is supported in the axial direction and is interposed between the aforementioned packing member and the smallest inner diameter portion of the inner container.

As described above, the container port plug of the present invention can be placed close to the shaft above the shoulder of the outer container because the sealing position of the packing between the inner circumference of the sealed container and the outer circumference of the middle pin can be close to the cap side. The minimum inner diameter portion of the inner container is provided to the portion on the side of the cap. Previously, as in Patent Document 1, since the minimum inner diameter portion of the inner container is located closer to the bottom side than the shoulder portion of the outer container, the outer container can be extended in the axial direction without being required to be extended. The inner diameter of the inner container is close to the side of the cap, and the capacity of the inner container is ensured to be larger in the axial direction. Therefore, even if the same capacity is secured, the bottom of the inner container can be increased, so that the container can be miniaturized.

As described above, since the present invention adopts the above configuration, the sealing portion of the tamping member can be brought close to the side of the ferrule cap without providing a threaded portion on the outer circumference of the middle yoke, so that the container can be miniaturized and the cleaning spigot can be When the inner circumference of the cover and the outer circumference of the middle bolt are in the gap, the middle bolt can be removed from the bolt cover, so that the cleaning property can be well maintained, and the buckle can be fastened at the filler support portion in the state where the middle bolt is removed. The stuffing is detached or detached, so there is no concern that the work will become difficult.

Hereinafter, a first embodiment of the present invention will be described based on the drawings. As shown in FIGS. 1 to 3, the first embodiment is a beverage container having a container 1 that is engageable in the axial direction in the axial direction of the mouth portion of the container 1, or a mouthpiece member 2 and a container port stopper. The container port plug includes: a threaded portion 31 having a threaded portion detachable from the container 1, a bolt cover 32 from the axial cover to the container 1, and a plug body 3 that is recessed from the axial direction of the bolt cover 32; and The cap cap 4 that freely covers the recessed space of the middle pin 33 is detached. The middle pin 33 has a packing member 34 that is fitted to the outer periphery thereof. The heat insulating chamber 5 is formed by the cap cap 4 and the middle pin 33. In a state in which the plug body 3 is fixed to the container 1 by the screw portion 31, the packing member 34 is interposed between the inner circumference of the container 1 and the outer circumference of the middle pin 33.

The container 1 is a double insulated container in which the inner container 11 and the outer container 12 are joined. The container 1 contains, for example, a vacuum double container. The container 1 has a container opening that is open on the top. The inner container 11 and the outer container 12 are each made of a stainless steel thin plate, and are formed with a shoulder and a neck by drawing. The minimum inner diameter portion 11a formed in the neck portion of the inner container 11 is present in a portion above the shoulder portion of the outer container 12 near the axial plug cap side as exemplified. The outer container 12 has a thread 12a that can be screwed to the outer portion of the threaded portion 31. In a state where the plug body 3 is fixed to the container 1, the cap 32 can be axially supported by the shoulder of the outer container 12, and it is interposed between the caulking member 34 and the minimum inner diameter portion 11a of the inner container 11. between. The mouthpiece member 2 can be omitted.

The threaded portion 31 includes a screw shaft portion that is screwed onto the container 1. The threaded portion 31 is provided on the inner circumference of the bolt cover 32 with the external thread 12a provided on the container 1. The axial direction is above and below the horizontal direction. One of the points in the up and down direction in the figure is the axis of the threaded portion 31, that is, the axial direction. The thread radial direction is horizontal. One of the dotted lines in the left and right directions in the figure indicates the radial direction of the thread.

As shown in FIGS. 1 and 4, the bolt cover 32 is composed of a cover portion 35 formed on the inner circumference of the threaded portion 31, a decorative panel 36 from the axial cover to the upper portion of the cover body 35, and together with the cover body 35. The pressing member 37 that sandwiches the decorative panel 36 is fixed. The cover main body 35 and the pressing member 37 are each formed by injection molding. The trim panel 36 has a metal surface. The trim panel 36 is positioned on the side of the thread radial and axial packing 34 by the overlap of the cover body 35. The pressing member 37 is rotatable from the axial direction to the inner circumference of the decorative panel 36 overlapping the cover body 35 and the inner circumferential side of the upper surface. The pressing member 37 has a claw portion 37a that protrudes toward the axial packing member 34 from a plurality of portions in the circumferential direction. The claw portion 37a is elastically inclined by the contact with the inner peripheral edge of the cover body 35 during the axial covering as described above, thereby elastically recovering over the inner peripheral edge, and reaching to be axially engaged with each other. position. The cover main body 35, the decorative panel 36, and the pressing member 37 are integrally joined by the engagement of the claw portions 37a and the plurality of portions of the cover main body 35 in the circumferential direction.

As shown in Fig. 1 and Fig. 3, the center pin 33 is composed of a member having an inner and outer circumference recessed from the side of the plug member 32 toward the axial packing member 34, and having a recessed space open in the axial direction. In the outer circumference of the middle pin 33, a portion of the thread facing the thread portion 31 in the radial direction is provided with a stuffer support portion 33a which can insert the stuffing member 34 from the axial direction. When the plug body 3 is screwed to the container 1, the stuffer support portion 33a can restrict the range in which the packing member 34 is displaced in the axial direction with respect to the outer circumference of the center pin 33 within a regular range. "Regular range" means a range in which the state between the middle plug 33 and the inner circumference of the inner container 11 is sealed in a watertight manner. The axially intermediate portion formed on the cylindrical surface of the outer periphery of the packing member 34 is pressed into the minimum inner diameter portion 11a of the inner container 11, and is secured by the fastening of the necessary degree. Within the range of the state in which the water permeable is sealed.

The wadding support portion 33a has a ridge portion on the lower side in the drawing in the circumferential direction and a ridge portion on the upper side in the drawing. The packing 34 has a profile A fitting portion that is continuous in the circumferential direction. The fitting of the caulking member 34 toward the axial packing side is restricted by press-fitting the fitting portion of the caulking member 34 at the lower rib portion in the drawing of the tamping member supporting portion 33a. The axial packing side corresponds to the lower side of the drawing. The displacement toward the upper side in the drawing of the packing 34 is restricted by the support of the ridge portion on the upper side in the drawing by the tamping support portion 33a.

As shown in Fig. 1 and Fig. 2, the middle pin 33 and the bolt cover 32 are detachably fastened to the portion of the stuffer support portion 33a on the side of the axial bolt cap. The side of the axial bolt cap corresponds to the upper side of the figure.

Specifically, the middle pin 33 has a locking claw 33b that protrudes in the circumferential direction of the plurality of portions on the side of the axial bolt cap in comparison with the inner and outer portions of the center. The bolt cover 32 has a claw receiving portion 37b that is engaged with the locking claw 33b. The claw receiving portion 37b is provided on the pressing member 37. The latching claws 33b of the middle pin 33 are elastically retracted beyond the claw receiving portion by being axially contacted and elastically inclined with respect to the claw receiving portion 37b corresponding to the circumferential direction, and reach a position where they are engaged with each other in the axial direction. The middle latch 33 and the bolt cover 32 are integrally coupled by the engagement of the plurality of portions of the claws 33b and the claw receiving portion 37b in the circumferential direction.

The middle pin 33 includes an outer circumference of the tamping support portion 33a, a locking claw 33b, and a circumferential direction on both sides of the locking claw 33b with a gap 33c protruding from the inner and outer circumferences of the locking member 33a. Abuts the wall 33d. The abutting wall 33d abuts against the bolt cover 32 in the axial direction while the middle bolt 33 is locked to the bolt cover 33. By this abutment, the middle pin 33 is positioned so as not to be displaced toward the axial cap side with respect to the cap 32. Further, between the detent pawl 33b and the bolt cover 32, an axial gap which is useful to allow the inclination of the detent pawl 33b is secured. The locking claws 33b are arranged in a pair in the radial direction of the thread. Therefore, by sandwiching the two portions of the locking claws 33b with the fingers, it is possible to easily press all of the locking claws 33b and to forcibly overwhelm them in the oblique direction described above, thereby releasing the fastening. After it is released, the middle pin 33 and the bolt cover 32 can be separated in the axial direction.

The circumferential positioning between the middle pin 33 and the bolt cover 32 is derived from the circumferential direction of the regulating wall 37c formed on both sides of the claw receiving portion 37b and the locking claw 33b. In order to form the heat insulating chamber 5 or the inner and outer circumferences of the container 1 in a circumferential shape, the middle plug 33 and the bolt cover 32 are also provided integrally on the inner and outer circumferences of the circumference. Since the circumferential positioning of each of the locking claws 33b and the regulation wall 37c is obtained, even if another circumferential positioning structure is not provided between the middle bolt 33 and the bolt cover 32, the middle bolt 33 can be placed relative to the bolt cover 32. Rotation is prohibited in the circumferential direction.

As shown in FIGS. 1 and 5, the cap cap 4 has a tubular portion 41 that is inserted into the inner periphery of the intermediate pin 33 and a cap packing 42 that is fitted to the outer periphery of the tubular portion 41. The cap packing 42 seals between the inner circumference of the middle pin 33 and the outer circumference of the tubular portion 41. The top surface of the cap cap 4 is formed in a plane orthogonal to the axial direction. In order to eliminate the necessity of arranging the top surface of the cap cover 4 to form the wall 43 or integrally projecting outward in the axial direction by providing the claw receiving portion 37b of the bolt cover 32, the claw receiving portion 37b is made to be opposed to the abutting wall 33d. The abutting position with the bolt cover 32 is set to be recessed toward the axial packing side.

The cap cap 4 can be attached from the axial cap to the plug body 3 in a state where the cap 32 and the middle pin 33 are combined as described above to assemble the plug body 3. The anchoring force of the cap cap 4 to the plug body 3 is derived from the adhesion between the cap filler 42 and the inner circumference of the middle pin 33. The cylindrical portion 41 of the cap cap 4 covering the recessed space of the middle pin 33, the cap packing member 42 and the top surface forming wall 43, and the middle pin 33 form the heat insulating chamber 5. In order to utilize the recessed depth of the middle pin 33, the capacity of the heat insulating chamber 5 is obtained, and compared with the sealing position (minimum inner diameter portion 11a) of the packing member 34 is not low, and heat is formed in the concave bottom surface of the middle pin 33. The deepest portion of the bottom surface of the chamber 5 is the axial plug cap side compared to the sealing position of the packing member 34, and is formed in comparison with the thread starting end of the most axial bolt cap side of the threaded portion 31. low. Further, in order to obtain the capacity of the heat insulating chamber 5, in the top surface forming wall 43, the portion of the ceiling which becomes the heat insulating chamber 5 is formed higher in the axial direction than the plug cover 32. Since the capping member 42 is sealed, even if the retaining claw 33b is formed by the gap 33c of the middle pin 33, there is no need to worry about water immersion from the gap 33c toward the heat insulating chamber 5. In addition, the water droplets adhered during cleaning or the residual droplets attached to the side of the cap 4 as compared with the stuffing member 34 during the cleaning may reach the top surface of the cap cover 4 from the gap 33c to form the wall 43 and the cap. Between 32. For this reason, the outer circumference of the tubular portion 41 of the cap cap 4 and the gap between the top surface forming wall 43 and the bolt cover 32 are ensured throughout the entire circumference and the outside. Therefore, water droplets or the like can be discharged to the outside by appropriately shaking the container port stopper.

The yoke cap 4 which is detachably attached to the yoke body 3 is provided with an inclination restricting portion 44 which is inserted from the axial direction to allow the inclination of the aforementioned detent pawl 33b. The inclination restricting portion 44 of the cap cap 4 restricts the inclination of the clinching claw 33b to a range in which it cannot escape from the claw receiving portion 37b in a state of being attached to the plug body 3. Therefore, even if the middle pin 33 is forcibly tilted with respect to the axial direction toward the side corresponding to the inclination direction of the locking claw 33b, and the locking claw 33b is pressed against the claw receiving portion 37b, the buckle cap 4 can be used to prevent the buckle The claw 33b is released from the claw receiving portion 37b.

Specifically, the inclination restricting portion 44 is provided by the tubular portion 41 which is the inner insertion portion of the middle pin 33. The inclination restricting portion 44 of the tubular portion 41 can restrict the inclination of the locking claw 33b from the inner side of the middle pin 33. By the use of the tubular portion 41, the wall surface structure of the cap cap 4 can be prevented from being complicated as compared with the case where the dedicated tilt restricting portion is protruded from the tubular portion 41. Further, the inclination restricting portion 44 is formed to protrude on the outer circumference of the tubular portion 41 in the radial direction of the thread. Thus, the inclination restricting portion 44 is partially protruded like a rib only to avoid useless processing. The inclination restricting portion 44 is provided to eliminate the circumferential position of the locking claw 33b, for example, and can be provided so as to protrude over the entire circumference of the outer circumference.

Since the inclination restricting portion 44 is provided in the circumferential direction, in order to prevent the inclination restricting portion 44 from coming out of the range of the support buckle claw 33b in the circumferential direction, the circumferential positioning between the cap cap 4 and the bolt cover 32 is required. This positioning originates from the circumferential engagement of the top surface forming wall 43 of the cap cap 4 with the second gauge wall 37d of the bolt cover 32 shown in FIG. Since the second regulating wall 37d is formed of the same mold together with the claw receiving portion 37b and the like, it is partially recessed toward the axial packing side. As shown in Figs. 1 and 3, similarly to the bolt cover 32 and the middle bolt 33, the tubular portion 41 of the cap cap 4 is also required to be integrally provided on the inner and outer circumferences of the circumference. Since the circumferential positioning of the second regulating wall 37d and the top surface forming wall 43 shown in FIGS. 4 and 5 can be obtained, as shown in FIGS. 1 and 3, even in the bolt cover 32 and the cap cap 4 The other circumferential positioning structure is not provided, and the cap cover 4 is also prohibited from rotating in the circumferential direction with respect to the cap cover 32.

Further, the middle pin 33 is provided as one member by injection molding. The middle bolt 33 can be separated from the bolt cover 32 by one part. However, if the middle bolt is provided in combination with a plurality of members, the number of parts is increased, and the cleaning of the joint gap is troublesome.

In the first embodiment described above, when the middle pin 33 is separated from the bolt cover 32, the outer circumference of the plug 33 in the stuffing member support portion 33a to which the packing member 34 is attached is included, and the outer peripheral portion is on the axial side of the cap portion. The buckle claw 33b and the abutment wall 33d are separated from the bolt cover 32. Therefore, as shown in Fig. 1, the inner circumference and the lower surface of the bolt cover 32 which forms the gap between the inner circumference of the bolt cover 32 and the outer circumference of the middle bolt 33 are exposed to be large due to the disappearance of the middle bolt 33. Therefore, it is easy to directly clean the inner circumference and the lower surface of the cap 32. As described above, in the first embodiment, the cleanliness in the gap between the inner circumference of the cap 32 and the outer circumference of the center pin 33 can be favorably maintained. Further, the self-separating plug 33 can simply snap or detach the tampon 34 from the tampon support portion 33a without interfering with other members.

Since the threaded portion 31 of the container mouth plug is provided on the inner circumference of the bolt cover 32, the stuffer support portion 33a is provided in the outer circumference of the middle pin 33 from the portion where the thread portion 31 faces the thread in the radial direction. Thereby, since the sealing position of the packing member 34 can be brought close to the side of the cap cap 4, it is possible to ensure a large capacity in the container 1 in the axial direction. Even if the same capacity is ensured, the container 1 can be miniaturized. That is, in the container 1 including the double insulated container, since the minimum inner diameter portion 11a of the inner container 11 is provided so as to be present on the side of the outer container 12 above the shoulder of the outer side of the axial cap 4, The minimum inner diameter portion 11a of the inner container 11 can be brought close to the side of the cap cap 4 without extending the outer container 12 in the axial direction, and the capacity of the inner container 11 can be ensured to be large in the axial direction. Therefore, since the bottom of the inner container 11 can be raised even if the same capacity is secured, the container 1 can be miniaturized.

The second embodiment will be described with reference to Figs. 6 to 8 . In the following description, the differences from the first embodiment will be mainly described, and the same constituent elements will be designated by the same names, and the description of the overlapping items will be omitted. As shown in the figure, in the second embodiment, the decorative panel or the like can be omitted, and the cover 61 can be constituted by one component. The bolt cover 61 may have a second inner peripheral wall extending from the inner peripheral edge of the upper surface portion toward the axial packing side instead of the pressing member. Moreover, the buckle of the middle bolt 62 and the bolt cover 61 is a quick snap-fit structure. The cylindrical portion of the cap cap 63 is axially abutted against the wall portion forming the inner and outer circumferences of the middle pin 62 to form a heat insulating chamber which is not inserted into the inner side of the inner periphery of the middle pin 62. Therefore, the capacity of the heat insulating chamber can be increased. In addition, the second inner peripheral wall of the cap 61 and the tubular portion of the cap cap 63 are sealed by a cap packing.

A quick snap groove 64 is provided on the outer circumference of the middle pin 62. The quick card claw 65 is protruded from the second inner peripheral wall toward the axial packing side at a plurality of circumferential portions of the bolt cover 61. As shown in FIG. 8(a) and FIG. 8(b), if the cap cap 63 is attached to the plug body after the quick snap-off, as shown in FIG. 8(c), the cap cap can be made. The blocking portion 66 of the 63 is inserted into the recess in the axial direction from the insertion opening of the quick snap groove 64. By the clogging portion 66, it is possible to surely prevent the displacement toward the canceling rotation side of the quick ejector claw 65.

Each of the above embodiments is applied to a portable beverage container. However, the technical scope of the present invention is not limited to the above-described embodiments, and all modifications are included in the scope of the technical idea described in the patent application.
