Description

Technical Field

[0001] The invention relates to a cover unit and a container with a cover. Background Art

[0002] Conventionally, there is a container with a lid which includes a lid unit detachably attached to a container body having an upper opening (for example, refer to Patent Document 1 listed below).

[0003] Such a cap unit has a structure including a cap body that closes the upper opening of the container body, and the cap body is attached to the container body by screwing.

[0004] The cap unit has a waterproof packing detachably mounted on the cap body, and the space between the container body and the cap body is sealed (waterproofed) by the waterproof packing.

[0005] When the cover body is screwed onto the container body, the water-stopping seal member contacts the extension protruding from the inner side of the container body over the entire circumference, thereby being in a state of being elastically deformed while being in close contact with the extension over the entire circumference. Thus, the container body and the cover body can be sealed (waterproofed) by the water-stopping seal member.

[0008] However, the above-mentioned waterproof packing is composed of an annular elastic member and is fitted to the outer peripheral portion of the lower end side of the cover body. On the other hand, the waterproof packing can be removed from the cover body by elastically deforming itself (stretching and extending).

[0009] Thus, the waterproof packing and the cover body can be cleaned separately, and the space between the waterproof packing and the cover body can be kept clean.

[0010] However, the water-stop packing embedded in the outer peripheral portion of the lower end side of the cover body becomes a difficult-to-remove structure. Therefore, a pinch piece is provided to facilitate the removal of the water-stop packing. In particular, when cleaning the cover unit, if the water-stop packing becomes wet, the pinch piece cannot be pinched well, making it very difficult to remove the water-stop packing. In addition, depending on the direction in which the water-stop packing is installed, there is a situation in which the pinch piece is located in the flow path for the contents (beverage) of the container body to be discharged, thereby disturbing the discharge flow. Summary of the invention

[0011] The present invention is proposed in view of such existing situation, and its purpose is to provide a cover unit that can well maintain the airtightness based on the water-stop packing and easily remove the water-stop packing regardless of the installation direction, and a covered container that can further improve the ease of use by having such a cover unit.

DETAILED DESCRIPTION

[0048] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0049] (First Embodiment)

[0050] First, as a first embodiment of the present invention, for example, Figure 1 to Figure 5 The lidded container 100 of the lid unit 1A shown will be described.

[0051] also, Figure 1 It is a cross-sectional view showing the structure of the container 100 with a lid including the lid unit 1A. Figure 2 This is a perspective view of the port forming member 11 and the water stopping packing 23 included in the cover unit 1A as viewed from the bottom. Figure 3 It is a perspective view showing a state where the water stop packing 23 is removed from the port forming member 11 . Figure 4 It is a cross-sectional view showing the waterproof packing 23 fitted into the fitting recess 22 of the port forming member 11 . Figure 5It is a cross-sectional view showing a position where a cutout portion 24 of a water stop packing 23 fitted into a fitting recess 22 of a port forming member 11 is provided.

[0052] like Figure 1 As shown, the lidded container 100 of the present embodiment comprises a lid unit 1A of the present embodiment and a container body 2 to which the lid unit 1A is detachably mounted. The lidded container 100 is a beverage container that can keep a beverage (content) contained in the container body 2 warm or cold by means of the container body 2 having a vacuum heat insulation structure.

[0053] Specifically, the container body 2 is composed of a double-layered container, which includes an outer container 3 and an inner container 4, which are cylindrical and have a bottom and are made of, for example, stainless steel, and the inner container 4 is accommodated inside the outer container 3, and the opening edges of each other are joined. In addition, a vacuum insulation layer 5 is provided between the outer container 3 and the inner container 4. The vacuum insulation layer 5 can be formed by, for example, blocking the exhaust hole provided on the bottom surface of the outer container 3 in a chamber that is decompressed (evacuated) to a high vacuum.

[0054] The container body 2 has a bottom portion 2a having a substantially circular shape, a barrel portion 2b which rises substantially cylindrically from the outer periphery of the bottom portion 2a, and a substantially cylindrical neck portion 2c which is reduced in diameter on the upper side of the barrel portion 2b. The upper end of the neck portion 2c is opened in a circular shape as an upper opening 2d of the container body 2. The inner peripheral surface of the neck portion 2c is reduced in diameter compared to the inner peripheral surface of the barrel portion 2b. An annular extension portion 6 is provided protrudingly over the entire circumference of the inner peripheral surface of the neck portion 2c.

[0055] The lidded container 100 of the present embodiment has a generally cylindrical appearance as a whole, but the appearance of the lidded container 100 is not particularly limited and can be appropriately modified according to size, design, etc. In addition, the outer peripheral surface of the container body 2 may be painted, printed, etc.

[0056] The cap unit 1A of the present embodiment includes a cap body 7 that closes the upper opening 2 d of the container body 2 , and a cap body 9 that is rotatably attached to the cap body 7 via a first hinge portion 8 .

[0057] In addition, in the following description, the side on which the cover body 9 is installed on the cover main body 7 via the first hinge portion 8 is set as the "rear side (back side)" of the cover unit 1A (container with cover 100), and the opposite side is set as the "front side (front side)" of the cover unit 1A (container with cover 100) for explanation.

[0058] The cap body 7 includes a cylindrical outer tube member 10 made of, for example, a heat-resistant resin and a port forming member 11. The port forming member 11 has a liquid passage 12 communicating with the inside of the container body 2 as a port forming portion.

[0059] The outer tube member 10 has a peripheral wall portion 10a formed in a substantially cylindrical shape so as to be continuous with the barrel portion 2b of the container body 2, and an upper wall portion 10c having an opening portion 10b whose diameter is reduced compared to the peripheral wall portion 10a formed at an upper portion of the peripheral wall portion 10a.

[0060] The cap body 7 is detachably mounted on the neck portion 2c of the container body 2 by screwing. Therefore, an internal thread portion 13 is provided on the inner peripheral surface of the peripheral wall portion 10a (outer cylinder member 10). On the other hand, an external thread portion 14 screwed with the internal thread portion 13 is provided on the outer peripheral surface of the neck portion 2c.

[0061] like Figure 1 to Figure 3 As shown, the port forming member 11 includes: an upper port forming portion 11a that protrudes upward from the opening portion 10b of the outer tube member 10; a lower port forming portion 11b that protrudes downward from the opening portion 10b of the outer tube member 10; and a bottom wall portion 11c that forms a liquid passage 12.

[0062] The upper port forming portion 11a is provided as an injection port or a drinking port, and is provided to protrude obliquely from the front side of the port forming member 11 (port forming portion). The lower port forming portion 11b is provided as a portion that is embedded into the inner side of the container body 2 from the upper opening portion 2d of the container body 2, and is provided to protrude from the lower side of the upper port forming portion 11a in a substantially cylindrical shape. The liquid passage 12 opens in a circular shape at the bottom of the bottom wall portion 11c that is slightly inclined downward from the rear side to the front side.

[0063] The port forming member 11 (port forming portion) is detachably mounted to the opening portion 10b of the outer cylinder member 10 via the port attaching and detaching mechanism 15. The port attaching and detaching mechanism 15 includes: a first claw portion 16 provided on the front side of the port forming member 11; a locking member 18 which is mounted on the rear side of the port forming member 11 and provided with a second claw portion 17; and a biasing member 19 which is disposed between the port forming member 11 and the locking member 18.

[0064] The first claw 16 is located on the outer peripheral surface of the mouth-forming member 11, and is provided to protrude forward from the lower side of the upper mouth-forming portion 11a. The second claw 17 is provided to protrude rearward from a position near the upper end of the locking member 18. The locking member 18 is installed to be freely rotatable in the front-rear direction via a second hinge 18a provided on the lower side of the rear side of the mouth-forming member 11.

[0065] The urging member 19 is made of an elastic member such as rubber or elastomer and is attached to the surface of the locking member 18 facing the port forming member 11. The urging member 19 may be a spring member such as a coil spring instead of the elastic member.

[0066] When the upper end side of the locking member 18 is rotated forward (on one side of the rotation direction), the urging member 19 is compressed (elastically deformed) between the locking member 18 and the opening forming member 11, thereby urging the locking member 18 backward (on the other side of the rotation direction).

[0067] The port attaching and detaching mechanism 15 includes a first engaged portion 20 provided at the front side around the opening 10 b of the outer tube member 10 and a second engaged portion 21 provided at the rear side around the opening 10 b of the outer tube member 10 .

[0068] In the mouth assembly and disassembly mechanism 15, the mouth forming component 11 is embedded into the inner side of the opening portion 10b of the outer tube component 10 from the lower side, and the first claw portion 16 is clamped to the first clamped portion 20, and the second claw portion 17 is clamped to the second clamped portion 21, thereby enabling the mouth forming component 11 (mouth forming portion) to be installed in the opening portion 10b of the outer tube component 10.

[0069] On the other hand, in the port attaching and detaching mechanism 15, the upper end side of the locking member 18 is rotated forward to release the locking state of the second claw portion 17 relative to the second locked portion 21. As a result, the locking state of the first claw portion 16 relative to the first locked portion 20 can be released, and the port forming member 11 can be removed from the opening portion 10b of the outer tube member 10 to the lower side.

[0070] In addition, in the present embodiment, the port forming member 11 (port forming portion) is detachably mounted on the outer tube member 10 (cap body 7). On the other hand, the port forming member 11 is not necessarily a detachably mounted structure, and may be a structure integrally formed with the outer tube member 10, or a structure integrally formed in an inseparable manner by interference fit or the like.

[0071] The lower port forming portion 11b of the port forming member 11 (port forming portion) is a portion that is fitted into the container body 2 from the upper opening 2d, and an annular fitting recess 22 serving as a fitting portion is provided over the entire periphery of the outer circumference on the lower end side.

[0072] A water-stop packing 23 is detachably mounted on the fitting recess 22 of the port forming member 11. The water-stop packing 23 is a circular ring-shaped sealing member for sealing the space between the extension 6 (container body 2) and the port forming member 11 (cover body 7). Figure 4 and Figure 5As shown, it has a circular shape in a cross section taken in a direction perpendicular to its circumferential direction.

[0073] The fitting recessed portion 22 has a shape that is recessed in an arc shape corresponding to the outer shape of the waterproof packing 23 in a cross section taken in a direction perpendicular to the circumferential direction thereof.

[0074] The water-stopping packing 23 is composed of elastic components such as heat-resistant rubber, elastomer, etc., such as silicone rubber and fluororubber. In particular, in the present embodiment, fluororubber, which is an elastic component containing fluorine, is used as the water-stopping packing 23. Fluororubber has excellent chemical resistance and has the characteristics of not easily carrying the smell of the contents.

[0075] As the fluororubber, for example, a material such as a vinylidene fluoride-based (FKM), a tetrafluoroethylene-propylene-based (FEPM), or a tetrafluoroethylene-perfluorovinyl ether-based (FFKM)-based material can be used.

[0076] The waterproof packing 23 is mounted on the port forming member 11 (cover body 7) by being fitted into the fitting recess 22. On the other hand, the waterproof packing 23 can be removed from the fitting recess 22 (port forming member 11) by elastically deforming (stretching and elongating) itself.

[0077] Thus, the waterproof packing 23 and the port forming member 11 can be cleaned separately, and the space between the waterproof packing 23 and the port forming member 11 can be kept clean.

[0078] The lower port forming portion 11b (port forming member 11) is provided with a cutout portion 24 formed by cutting out a part of the fitting recess 22. The cutout portion 24 is provided so that a part of the inner peripheral side of the waterproof packing 23 fitted into the fitting recess 22 is exposed.

[0079] Specifically, the cutout 24 is provided by cutting away a portion of the lower peripheral wall 22a forming the fitting recess 22 on the lower surface of the lower port forming portion 11b to expose the bottom wall 11c. In addition, the cutout 24 is provided by cutting away a portion of the lower peripheral wall 22a located on one side in the left-right direction of the port forming member 11 (port forming portion). In addition, the cutout 24 is cut away in a concave shape along the circumferential direction of the lower peripheral wall 22a as viewed from the lower surface side within a portion of the inner peripheral side of the finger hook waterproof packing 23.

[0080] In the cover unit 1A of the present embodiment, by exposing a portion of the inner peripheral side of the water-stopping packing 23 embedded in the above-mentioned fitting recess 22 from the cut-out portion 24, the water-stopping packing 23 can be easily removed from the fitting recess 22 while the exposed portion of the water-stopping packing 23 is hooked with a finger and stretched toward the outside.

[0081] In particular, when using the above-mentioned water-stopping gasket 23 made of fluororubber, since fluororubber is a material that is not easy to stretch compared to silicone rubber, by providing such a cutout portion 24 formed by cutting off a part of the lower side peripheral wall 22a (mating recess 22), the water-stopping gasket 23 can be easily removed from the mating recess 22.

[0082] On the other hand, Figure 4 and Figure 5 As shown, the waterproof packing 23 fitted into the fitting recess 22 abuts against the extension 6 of the container body 2 when the cap body 7 is attached to the container body 2, thereby being in close contact with the extension 6 over the entire circumference while being elastically deformed.

[0083] Specifically, the waterproof packing 23 is in contact with the inclined surface on the entrance side of the extension portion 6. At this time, the waterproof packing 23 is in contact with the inner surface of the fitting recess 22 at a position opposite to the position in contact with the extension portion 6.

[0084] The water stop packing 23 is located at the lower part of the outer peripheral side ( Figure 5 The lower right side of the paper in the figure, the clock direction of 4:30) abuts against the inclined surface of the entrance side of the extension part 6. At this time, as a direction relative to the position abutting against the extension part 6, the water stop packing 23 is in the upper direction of its inner peripheral side ( Figure 5 The upper left side of the paper (10:30 o'clock direction) abuts against the fitting recess 22.

[0085] In addition, if Figure 4 As shown, the fitting recess 22 other than the cutout 24 corresponds to the substantially semicircular cross-section of the water-stopping packing 23 and has a substantially semicircular cross-section concave shape. Figure 5 As shown, the fitting recess 22 in the cutout portion 24 corresponds to about 1 / 2 of the roughly semicircular cross-section of the waterproof packing 23 (about 1 / 4 of the entire cross-section), and has a shape that is concave in an arc shape about 1 / 4 of the entire cross-section. Specifically, the waterproof packing 23 abuts against the fitting recess 22 in the front and rear of the cross-section circumferential direction, with the direction opposite to the position abutting against the extension 6 as the center.

[0086] More specifically, the upper side (in the circumferential direction of the cross section) of the waterproof packing 23 is centered on the direction opposite to the position where the inclined surface on the entrance side of the extension portion 6 abuts. Figure 5 The outer peripheral end of the upper end of the engaging recess 22 extends to the upper side of the top surface of the protruding portion 6 (the inner peripheral end).

[0087] In addition, with the direction opposite to the position of the waterproof packing 23 that contacts the extension 6 as the center, the lower side in the circumferential direction of the cross section (with the Figure 5The lower end portion of the inner peripheral side of the fitting recess 22 extends to the bottom wall portion 11c.

[0088] In this embodiment, the cap body 7 is mounted on the container body 2 by screwing the external thread 14 of the container body 2 and the internal thread 13 of the outer tube member 10. At this time, the water stop packing 23 is compressed between the inclined surface on the entrance side of the extension 6 and the inner surface of the fitting recess 22.

[0089] In addition, when the cover body 7 is mounted on the container body 2, the port forming member 11 moves downward, so that stress in the vertical shearing direction between the extension 6 and the fitting recess 22 is applied to the water stop packing 23. Therefore, the outer peripheral end of the upper end of the fitting recess 22 extends above the top surface (inner peripheral end) of the extension 6, so that when the cover body 7 is mounted on the container body 2, the water stop packing 23 can be prevented from rolling up and falling off.

[0090] In addition, at the cutout portion 24, the lower end portion of the inner peripheral side of the fitting recess 22 extends to the bottom wall portion 11c, so that the finger can be pressed against the bottom wall portion 11c and slid toward the outer peripheral side to hook the finger on the water-stopping packing 23, thereby making it easy to remove the water-stopping packing 23 from the fitting recess 22.

[0091] The water-stopping seal 23 is compressed between the fitting recess 22 (mouth forming component 11) and the extension 6 (container body), and is in close contact with the fitting recess 22 and the extension 6 throughout the entire circumference while being elastically deformed, thereby preventing leakage from the entire circumference including the cutout 24.

[0092] Therefore, in the cover unit 1A of this embodiment, even when the above-mentioned cutout portion 24 is provided, the water-stopping seal 23 can be closely attached to the extension portion 6, and the airtightness (water-stopping property) between the extension portion 6 (container body 2) and the mouth forming component 11 (cover body 7) can be maintained at a good level.

[0093] In addition, the position of the cutout portion 24 is not necessarily limited to the structure arranged on one side of the above-mentioned mouth forming member 11 (mouth forming portion) in the left-right direction, and can also be arranged at other positions such as the rear side of the mouth forming member 11. In addition, the cutout portion 24 can also be provided at multiple locations on the circumference of the fitting recess 22.

[0094] The cover 9 opens and closes the liquid passage 12 of the port forming member 11 (port forming portion), and is made of, for example, a heat-resistant resin. The cover 9 has a peripheral wall portion 9a formed in a substantially cylindrical shape in a manner continuous with the peripheral wall portion 10a of the outer cylinder member 10; a top wall portion 9b covering the top surface of the peripheral wall portion 9a; and a substantially cylindrical inner wall portion 9c descending from the lower surface of the top wall portion 9b while penetrating the top wall portion 9b.

[0095] A cover packing 25 is provided inside the cover body 9 to seal the liquid passage 12 of the port forming member 11. The cover packing 25 is a bottomed cylindrical sealing member for sealing the liquid passage 12. The cover packing 25 is made of an elastic member, and for example, a member of the same material as the above-mentioned water-stop packing 23 can be used.

[0096] The cover packing 25 is detachably mounted on the cover body 9. Specifically, the cover packing 25 is detachably mounted on the lower end side of the inner wall portion 9c in a state where the inner wall portion 9c is fitted into the center hole 25a inside the inner wall portion 9c. The front end of the cover packing 25 is formed into a dome shape.

[0097] In the cap unit 1A of this embodiment, when the cap body 9 closes the upper part of the cap main body 7, the cap packing 25 is in close contact with the periphery of the liquid passage 12 while elastically deforming. Thus, the liquid passage 12 of the port forming member 11 (port forming portion) can be closed.

[0098] On the other hand, by removing the cover packing 25 from the inner wall portion 9 c (cover body 9 ), the cover packing 25 and the cover body 9 can be cleaned separately, and the space between the cover packing 25 and the cover body 9 can be kept hygienic.

[0099] A cover member 26 covering the upper end of the inner wall 9c is mounted on the upper surface of the top wall 9b. The cover member 26 is made of the same material as the cover body 9 and is formed in a substantially disk shape. On the other hand, a recessed portion 9d having a shape corresponding to the cover member 26 is provided on the upper surface of the top wall 9b. The cover member 26 is embedded in the inner side of the recessed portion 9d.

[0100] In addition, in the present embodiment, the cover member 26 described above is a member separate from the cover body 9 , but may be formed integrally with the cover body 9 .

[0101] A first urging member (not shown) is provided between the cover body 9 and the first hinge portion 8 . The first urging member is composed of a spring member such as a torsion spring, and is attached to the inner side of the first hinge portion 8 .

[0102] The cover body 9 is urged by the first urging member in the direction of the liquid passage port 12 of the opening forming member 11 (opening direction).

[0103] The first urging member is not limited to the above-mentioned spring member, and may be, for example, an annular elastic member made of rubber, elastomer, etc., hung between the cover body 9 and the cover main body 7 to urge the cover body 9 in the opening direction.

[0104] The cover unit 1A of the present embodiment includes a cover locking mechanism 27 that fixes the cover body 9 to the cover body 7 at a position where the cover body 9 closes the upper portion of the cover body 7 .

[0105] The cover lock mechanism 27 includes a lock member 29 rotatably mounted on the cover body 7 via a third hinge portion 28 , and an annular stopper 30 rotatably mounted on the cover body 7 via the third hinge portion 28 .

[0106] The lock member 29 is rotatably supported by the third hinge portion 28 provided on the front side of the outer tube member 10 (the peripheral wall portion 10a). The lock member 29 has a first arm portion 29a extending upward from the third hinge portion 28 and a second arm portion 29b extending downward from the third hinge portion 28.

[0107] A hook portion 31 is provided at a front end of the first arm portion 29 a (an upper end of the locking member 29 ) to project rearward.

[0108] A second urging member 32 made of an elastic member such as rubber or elastomer is disposed between the second arm portion 29b and the peripheral wall portion 10a. The second urging member 32 may be a spring member such as a coil spring instead of the elastic member.

[0109] The annular stopper 30 is composed of a partially open annular member, and both ends thereof are rotatably supported outside the third hinge portion 28. Thus, the annular stopper 30 can rotate in the vertical direction.

[0110] On the other hand, the cover lock mechanism 27 includes a lock receiving portion 33 on which the hook portion 31 of the lock member 29 is locked, and a stopper receiving portion 34 on which the annular stopper 30 is hooked.

[0111] The lock receiving portion 33 is composed of a claw portion protruding forward from the lower end of the front side of the cover body 9 (peripheral wall portion 9a). The stopper receiving portion 34 is composed of a wall portion protruding forward from a position around the lock receiving portion (claw portion) 33 surrounding the peripheral wall portion 9a in a shape corresponding to the inner side of the annular stopper 30.

[0112] In the cover lock mechanism 27 , when the cover 9 closes the upper portion of the cover body 7 , the hook 31 of the lock member 29 is locked to the lock receiving portion 33 , thereby maintaining the state in which the cover 9 closes the upper portion of the cover body 7 .

[0113] From this state, the second arm 29b of the lock member 29 is pressed against the biasing force of the second biasing member 32, thereby releasing the hook 31 from the lock receiving portion 33. Thus, the cover 9 biased by the first biasing member can be rotated in the opening direction.

[0114] On the other hand, in the cover locking mechanism 27, when the cover body 9 closes the upper part of the cover main body 7, the annular stopper 30 is hooked on the stopper receiving portion 34, thereby preventing the cover body 9 from rotating in the opening direction. Thus, in the cover locking mechanism 27, it is possible to prevent the cover body 9 from opening due to unnecessary operation of the locking member 29.

[0115] In the cover unit 1A of the present embodiment having the above-described structure, by exposing a portion of the inner peripheral side of the water-stopping packing 23 embedded in the above-mentioned fitting recess 22 from the cutout portion 24, the water-stopping packing 23 can be easily removed from the fitting recess 22 while stretching the exposed portion of the water-stopping packing 23 toward the outside.

[0116] In addition, in the cover unit 1A of this embodiment, even when the above-mentioned cutout portion 24 is provided, the water-stopping seal 23 can be closely attached to the extension portion 6, and the airtightness (water-stopping property) between the extension portion 6 (container body 2) and the mouth forming component 11 (cover body 7) can be maintained at a good level.

[0117] In addition, the water-stopping packing 23 does not have a pinching piece for detachment and can be freely installed in the circumferential direction of the mouth-forming member 11 (the lid body 7). Therefore, it is not affected by the installation direction, and when the contents (beverage) of the container body 2 are poured out, there is no situation where the pinching piece is located in the flow path and disturbs the flow of the pouring.

[0118] In addition, since it is not necessary to provide a pinch piece on the waterproof packing 23, a general-purpose packing such as an O-ring can be used. In this case, it is not necessary to prepare a dedicated waterproof packing 23, and the cost of the mold and the manufacturing cost can be suppressed to a low level.

[0119] Therefore, in the container with lid 100 of the present embodiment, by providing such a lid unit 1A, it is possible to further improve the usability.

[0120] (Second Embodiment)

[0121] Next, as a second embodiment of the present invention, for example, Figure 6 to Figure 10 The cover unit 1B shown will be described.

[0122] also, Figure 6 It is a cross-sectional view showing the structure of the container 100 with a lid including the lid unit 1B. Figure 7This is a perspective view of the port forming member 11 and the water stopping packing 23 included in the cover unit 1B as seen from the bottom. Figure 8 It is a perspective view showing a state where the water stop packing 23 is removed from the port forming member 11 . Fig. 9 It is a cross-sectional view showing the waterproof packing 23 fitted into the fitting recess 22 of the port forming member 11 . Fig.10 It is a cross-sectional view showing the position of the cutout portion 24 of the waterproof packing 23 fitted into the fitting recess 22 of the port forming member 11. In the following description, description of the parts equivalent to those of the cover unit 1A is omitted and the same reference numerals are given in the drawings.

[0123] like Figure 6 to Figure 8 As shown, the cover unit 1B of this embodiment has basically the same structure as the cover unit 1A except that the shapes of the fitting recess 22 and the waterproof packing 23 in the structure of the cover unit 1A are changed.

[0124] Specifically, the water stop packing 23 has a circular ring-shaped fitting protrusion 23a that fits into the fitting recess 22. Fig. 9 and Fig.10 As shown, the fitting projection 23 a has a substantially rectangular shape in a cross section taken in a direction perpendicular to the circumferential direction of the waterproof packing 23 .

[0125] The fitting recessed portion 22 has a substantially rectangular recessed shape corresponding to the outer shape of the fitting protruding portion 23 a in a cross section taken in a direction perpendicular to the circumferential direction thereof.

[0126] The waterproof packing 23 is mounted on the port forming member 11 (cover body 7) by fitting the fitting protrusion 23a into the fitting recess 22. On the other hand, the waterproof packing 23 can be removed from the fitting recess 22 (port forming member 11) by elastically deforming (stretching and elongating) itself.

[0127] Thus, the waterproof packing 23 and the port forming member 11 can be cleaned separately, and the space between the waterproof packing 23 and the port forming member 11 can be kept clean.

[0128] The lower port forming portion 11b (port forming member 11) is provided with a cutout portion 24 formed by cutting out a part of the fitting recess 22. The cutout portion 24 is provided so that a part of the inner peripheral side of the waterproof packing 23 fitted into the fitting recess 22 is exposed.

[0129] Specifically, the cutout 24 is provided by cutting away a portion of the lower peripheral wall 22a forming the fitting recess 22 on the lower surface of the lower port forming portion 11b to expose the bottom wall 11c. In addition, the cutout 24 is provided by cutting away a portion of the lower peripheral wall 22a located on one side in the left-right direction of the port forming member 11 (port forming portion). In addition, the cutout 24 is cut away in a concave shape along the circumferential direction of the lower peripheral wall 22a as viewed from the lower surface side within a portion of the inner peripheral side of the finger hook waterproof packing 23.

[0130] In the cover unit 1B of the present embodiment, by exposing a portion of the inner peripheral side of the water-stopping packing 23 embedded in the above-mentioned fitting recess 22 from the cut-out portion 24, the water-stopping packing 23 can be easily removed from the fitting recess 22 while the exposed portion of the water-stopping packing 23 is hooked with a finger and stretched toward the outside.

[0131] In particular, when using the above-mentioned water-stopping gasket 23 made of fluororubber, since fluororubber is a material that is not easy to stretch compared to silicone rubber, by providing such a cutout portion 24 formed by cutting off a part of the lower side peripheral wall 22a (mating recess 22), the water-stopping gasket 23 can be easily removed from the mating recess 22.

[0132] The fitting recess 22 has a tapered shape with a width gradually increasing from the bottom side toward the opening side. On the other hand, the fitting protrusion 23a has a tapered shape corresponding to the fitting recess 22 and a width gradually decreasing from the base end side toward the front end side.

[0133] By setting the fitting concave portion 22 and the fitting convex portion 23a in such a tapered shape, it is easy to attach and detach the water-stopping packing 23 to the fitting concave portion 22 of the port forming member 11 (port forming portion). In particular, when the water-stopping packing 23 made of fluororubber is used, since fluororubber is a material that is less likely to stretch than silicone rubber, it is preferable to set the fitting concave portion 22 and the fitting convex portion 23a in such a tapered shape.

[0134] The waterproof packing 23 includes an elastic flange portion 23b that projects from the outer peripheral surface of the fitting protrusion 23a over the entire circumference in the diameter expansion direction, and an elastic sleeve portion 23c that projects downward over the entire circumference from between the fitting protrusion 23a and the elastic flange portion 23b.

[0135] The elastic flange portion 23 b is a portion that comes into contact with the surface of the extension portion 6 on the entry side, and is located on the lower end side of the outer peripheral surface of the fitting projection 23 a.

[0136] On the other hand, the elastic sleeve portion 23c is a portion that contacts the top surface (inner peripheral end) of the extension portion 6 and is located between the lower surface of the fitting protrusion 23a and the lower surface of the elastic flange portion 23b. The inner peripheral surface of the elastic sleeve portion 23c is smoothly continuous from the lower surface of the fitting protrusion 23a toward the bottom with the inner peripheral side opened.

[0137] The elastic sleeve portion 23c has a tapered shape with its diameter gradually increasing downward, so that the relationship of (outer diameter of the elastic flange portion 23b)>(inner diameter of the extension portion 6)>(outer diameter of the elastic sleeve portion 23c) holds.

[0138] When the cover body 7 is mounted on the container body 2, the water stop packing 23 abuts against the extension 6 of the container body 2, thereby being in a state of being elastically deformed while being in close contact with the extension 6 over the entire circumference. Specifically, the lower surface of the elastic flange portion 23b abuts against the surface of the entrance side of the extension 6, and the outer peripheral surface of the elastic sleeve portion 23c abuts against the top side surface (inner peripheral side end) of the extension 6.

[0139] At this time, for the water-stopping packing 23, the elastic flange portion 23b elastically deforms along the surface on the entrance side of the extension portion 6, thereby causing the elastic sleeve portion 23c to elastically displace in the direction in which the outer peripheral surface of the elastic sleeve portion 23c abuts against the top surface (inner peripheral end) of the extension portion 6.

[0140] As a result, the elastic flange portion 23b is lifted upward along the surface of the extension portion 6 on the entrance side, and the elastic sleeve portion 23c is expanded in the diameter expansion direction accordingly, and is pressed by the top surface (inner peripheral end) of the extension portion 6.

[0141] This allows the waterproof packing 23 to be in close contact with the extension portion 6 , and allows the airtightness between the extension portion 6 (container body 2 ) and the port forming member 11 (lid body 7 ) to be kept good.

[0142] In addition, regarding the above-mentioned relationship of (outer diameter of elastic flange portion 23b)>(inner diameter of extension portion 6)>(outer diameter of elastic sleeve portion 23c), when the hardness of the water-stopping packing 23 is high, when a material with a small friction coefficient is used, etc., there is a situation where (inner diameter of extension portion 6)≤(outer diameter of elastic sleeve portion 23c).

[0143] In this case, when the cover body 7 is installed on the container body 2, the elastic sleeve portion 23c abuts against the extension portion 6 and also descends, whereby as a result, the elastic sleeve portion 23c only needs to abut against the top surface (inner peripheral end) of the extension portion 6 and be pressed.

[0144] In addition, if Fig. 9 and Fig.10 As shown, the waterproof packing 23 abuts against the inner surface of the fitting recess 22 at a position opposite to the position abutting against the extension 6 .

[0145] The water stop packing 23 is located at the lower part of the outer peripheral side ( Fig.10 The elastic flange 23b contacts the inclined surface of the extension 6 at the entrance side. At this time, the water stop packing 23 is in the upper direction of its inner circumference (in the direction opposite to the position of contact with the extension 6). Fig.10 (upper left of the paper, 10:30 direction on the clock), the engaging recess 22 abuts against the engaging protrusion 23a.

[0146] In addition, if Fig. 9 As shown, the fitting recess 22 other than the cutout 24 corresponds to the substantially rectangular cross-sectional shape of the waterproof packing 23 and has a shape that is recessed in a substantially rectangular cross-sectional shape. Fig.10 As shown, the fitting recess 22 in the cutout portion 24 corresponds to the inner circumferential side and the upper side of the fitting protrusion 23a, and has a substantially L-shaped concave shape in cross section. Specifically, the water stop packing 23 abuts against the fitting recess 22 in the front and rear of the cross section circumferential direction, with the direction opposite to the position abutting against the extension 6 as the center.

[0147] More specifically, the elastic flange portion 23b of the waterproof packing 23 and the inclined surface of the inlet side of the extension portion 6 are centered on the upper side of the cross-sectional circumferential direction (with the angle of 1.0047mm) of the waterproof packing 23. Fig.10 The outer peripheral end of the upper end of the engaging recess 22 extends to the upper side of the top surface of the protruding portion 6 (the inner peripheral end).

[0148] In addition, with the direction opposite to the position of the waterproof packing 23 that contacts the extension 6 as the center, the lower side in the circumferential direction of the cross section (with the Fig.10 The lower end portion of the inner peripheral side of the fitting recess 22 extends to the bottom wall portion 11c.

[0149] In this embodiment, the cap body 7 is mounted on the container body 2 by screwing the external thread 14 of the container body 2 and the internal thread 13 of the outer tube member 10. At this time, the water stop packing 23 is compressed between the inclined surface on the entrance side of the extension 6 and the inner surface of the fitting recess 22.

[0150] In addition, when the cover body 7 is mounted on the container body 2, the port forming member 11 moves downward, so that stress in the vertical shearing direction between the extension 6 and the fitting recess 22 is applied to the water stop packing 23. Therefore, the outer peripheral end of the upper end of the fitting recess 22 extends above the top surface (inner peripheral end) of the extension 6, so that when the cover body 7 is mounted on the container body 2, the water stop packing 23 can be prevented from rolling up and falling off.

[0151] In addition, at the cutout portion 24, the lower end portion of the inner peripheral side of the fitting recess 22 extends to the bottom wall portion 11c, so that the finger can be pressed against the bottom wall portion 11c and slid toward the outer peripheral side to hook the finger on the water-stopping packing 23, thereby making it easy to remove the water-stopping packing 23 from the fitting recess 22.

[0152] The water-stopping seal 23 is compressed between the fitting recess 22 (mouth forming component 11) and the extension portion 6 (container body), and is in close contact with the fitting recess 22 and the extension portion 6 throughout the entire circumference while being elastically deformed, thereby preventing liquid leakage from the position where the cutout portion 24 is provided.

[0153] Therefore, in the cover unit 1B of this embodiment, even when the above-mentioned cutout portion 24 is provided, the water-stopping seal 23 can be closely attached to the extension portion 6, and the airtightness (water-stopping property) between the extension portion 6 (container body 2) and the mouth forming component 11 (cover body 7) can be maintained at a good level.

[0154] In addition, the water-stopping packing 23 is not necessarily limited to the tapered shape having the elastic sleeve portion 23c gradually expanding in diameter downward. For example, the shape of the elastic sleeve portion 23c can be any shape as long as the elastic flange portion 23b is elastically deformed along the surface of the entrance side of the extension portion 6 so that the elastic sleeve portion 23c is elastically displaced in the direction of contact with the top surface (inner peripheral end) of the extension portion 6, and the shape can be appropriately changed.

[0155] In the cover unit 1B of the present embodiment having the above-described structure, similarly to the above-described cover unit 1A, by exposing a portion of the inner peripheral side of the water-stopping packing 23 embedded in the fitting recess 22 from the cutout portion 24, the water-stopping packing 23 can be easily removed from the fitting recess 22 while stretching the exposed portion of the water-stopping packing 23 toward the outside.

[0156] In addition, in the cover unit 1B of this embodiment, even when the above-mentioned cutout portion 24 is provided, the water-stopping seal 23 can be closely attached to the extension portion 6, and the airtightness (water-stopping property) between the extension portion 6 (container body 2) and the mouth forming component 11 (cover body 7) can be maintained at a good level.

[0157] In addition, the water-stopping packing 23 does not have a pinching piece for detachment and can be freely installed in the circumferential direction of the mouth-forming member 11 (the lid body 7). Therefore, it is not affected by the installation direction, and when the contents (beverage) of the container body 2 are poured out, there is no situation where the pinching piece is located in the flow path and disturbs the flow of the pouring.

[0158] Therefore, in the container with a lid 100 including such a lid unit 1B, it is possible to further improve the usability.

[0159] In addition, the present invention is not necessarily limited to the above-mentioned embodiment, and various modifications can be added within the scope not departing from the gist of the present invention.

[0160] For example, in the above embodiment, the cover units 1A and 1B are illustrated in which the cover body 9 is rotatably mounted on the cover body 7 via the first hinge portion 8, but the cover unit may be a cover unit in which the cover body is detachably mounted on the cover body by screwing.

[0161] In addition, in the above-mentioned embodiment, the cover units 1A and 1B are illustrated in which an annular fitting recess 22 serving as a fitting portion is provided on the outer peripheral portion of the lower end side of the above-mentioned mouth forming component 11 (mouth forming portion), but the present invention can also be applied to the following cover unit, namely: it is equipped with a cover body, the cover body having an outer cover covering the upper opening portion 2d of the container body 2, and a middle plug embedded in the inner side of the container body 2 from the upper opening portion 2d, and the water-stop packing is freely and detachably installed in the fitting recess (fitting portion) provided on the outer peripheral portion of the lower end side of the middle plug.

[0162] In addition, in the above-mentioned embodiment, the present invention is exemplified as being applied to a beverage container having a heat preservation / cooling function by means of a container body 2 having the above-mentioned vacuum insulation structure, but the present invention can be widely applied to a lidded container having a container body and a lid unit that is detachably mounted on the container body.
