Description

  The present invention relates to a lid for a beverage container, and more particularly to a lid suitable for being attached to a tumbler.

  Various types of beverage containers are provided that are easy to carry by putting a lid on a container body such as a tumbler or cup. The beverage container contains various drinking liquids such as coffee, tea, juice, and water. And there are many things which became a double structure so that it may have a heat retaining or cold retaining function. In addition, a lid is attached so as not to spill when carrying.

  Recently, there has been provided a lid with an opening so that it can be consumed without removing the lid one by one. Various types of plugs that can close and open the opening are also provided.

  However, in the case where the stopper is simply detachably provided on the lid, it is necessary to remove the stopper when drinking, and there is a trouble of opening the stopper or placing the removed stopper, which is not convenient. Therefore, there is a type in which an openable / closable stopper is attached to the lid, and the stopper is set at an open position or a closed position by, for example, sliding or swinging. For example, in Patent Document 1, a lid is provided at the tip of a dog-shaped lever, and the lid is opened and closed by swinging the lever. In Patent Document 2, a swinging lid is attached without using a lever, and is opened and closed by swinging the lid.

  Furthermore, instead of the type that swings the stopper, the lid is slidably attached to the lid and opened and closed.

JP 2007-197091 A Utility Model Registration No. 3150162

  In the type that opens and closes by swinging with a stopper at the tip of the lever as described above, the lever pops out of the container, and the lever swings when it is tilted or accidentally gripped. There is a problem that the stopper opens. Moreover, in order to adjust the outflow amount of the drinking liquid, it is necessary to open the lever while adjusting the opening of the lever, which makes it difficult to finely adjust the outflow amount.

  Further, in the case of a swing method or a slide method that does not use a lever, it can be opened and closed by swinging or sliding the stopper. Similarly, means for stopping the slide member and the swing member at an appropriate position is provided. If it is not used, there is a problem that the outflow amount cannot be finely adjusted.

  In addition, when these swing type or slide type plugs are used, they are integrated with the lid, and there is a problem that the swinging part and the sliding part cannot be cleaned well in cleaning after use. In addition, in the swing method and the slide method, since it is structurally difficult to reliably close the opening, drinking liquid may leak from the gap between the opening and the stopper when it falls down or tilts, which is inconvenient to carry. There is a problem that.

  The present invention has been made to solve the above-described problems, and is a lid attached to an opening of a beverage container for storing a drinking liquid, and is formed in a cylindrical outer lid body and the outer lid body. A mounting portion that is attached to the opening of the beverage container, a female screw portion that is formed at a lower portion of the inner peripheral surface of the outer lid body, and an outer edge that extends upward at the upper portion of the outer lid body An outer lid having a portion, a cylindrical inner lid main body, a male screw portion formed on a lower portion of the outer peripheral surface of the inner lid main body and screwed into the female screw portion of the outer lid main body, and an outer peripheral surface of the inner lid main body A packing holding part formed in the circumferential direction at the upper part of the inner lid body, and an outlet that penetrates the inner circumferential surface of the inner lid body between the male screw part and the packing holding part on the outer circumferential surface of the inner lid body, A bottom plate extending from a position above the outlet so as to close the inner lid body And an inner lid having a knob formed to project upward from the upper surface of the bottom plate portion or inward from the inner peripheral surface of the inner lid body, and the inner lid attached to the packing holding portion, A packing is provided that closes a gap between the inner lid body and the outer lid body when the male thread portion of the body is screwed into the female thread portion of the outer lid body to be in a closed state.

  The outflow port is provided adjacent to or close to the packing holding part, so that the liquid can be easily discharged from the outflow port by slightly rotating the inner lid in the opening direction. Further, when the inner lid is slightly turned from this state, the outer lid and the inner lid can be joined in a watertight manner by packing.

  The bottom plate portion is a lower inner peripheral surface of the inner lid body, extends downward from an upper position of the outlet, and is located at a lower portion of the inner lid body. Thereby, a bottom plate part can be set low in the inner lid body, and the overall height can be reduced in a compact manner while keeping the height of the lid low.

  The outer edge portion has a tapered inner peripheral surface that is formed on the inner peripheral surface of the outer lid main body and that expands continuously from the female screw portion. Accordingly, the thickness can be gradually reduced as the upper end portion of the outer edge portion is directed upward, and the mouth feel is improved during drinking. Further, the tapered inner peripheral surface has a concave shape that curves inward in the longitudinal section of the outer edge portion passing through the center line of the outer lid body, so that liquid temporarily stays in the concave portion during drinking. Therefore, it is possible to prevent the liquid from flowing out into the mouth suddenly and at a time due to a time lag when the liquid flows into the mouth during drinking.

  The outer edge part has a drinking mouth part partially extended upward, and the knob part is constituted by a ridge extending in the diameter direction of the inner lid body and spanning between inner peripheral surfaces. When the central portion of the ridge in the diametrical direction is lowered, the inner lid body is tightened in a state of being attached to the outer lid body, and is joined in a watertight manner by the packing, The knob is formed on the inner lid body so that the knob is parallel to a straight line that passes through the mouthpiece and is perpendicular to the center line of the outer lid body. As a result, when the user puts his / her mouth on the drinking mouth in a non-drinkable state with the lid closed, the upper lip touches the knob, so that it can be easily understood that the lid is closed.

  One end portion in the diametrical direction of the knob portion, and one end portion of the knob portion are located at the outer edge portion with respect to a straight line passing through the drinking mouth portion and perpendicular to the center line of the outer lid body. It has an open mark at the place to be. Thus, when the open marks are brought close to each other, it can be seen at a glance that the inner lid is in an open state. Therefore, it is avoided that the inner lid is accidentally carried in the open position. Further, at the open mark position, the knob portion is located 90 ° away from the drinking mouth portion, so that the upper lip does not hit the knob portion and can be easily drunk.

  The outlet is preferably a through hole formed in the inner lid body at a constant pitch in the circumferential direction. Thus, by forming the through holes at a constant pitch in the circumferential direction, it is possible to suppress the height of the inner lid while securing a constant outflow amount. In particular, by making the through hole a rectangular shape that is long in the circumferential direction, it is possible to further reduce the height of the inner lid while ensuring a certain amount of outflow. Further, by forming the through holes in the circumferential direction excluding the knob portion in the circumferential direction, it is possible to ensure a certain outflow amount while ensuring the strength of the knob portion.

  The packing holding part preferably has a tapered outer peripheral surface parallel to the tapered inner peripheral surface and a packing holding groove formed in the circumferential direction on the tapered outer peripheral surface.

  It is preferable to have a through-hole through which the portable strap passes at a position rotated by 180 ° from the drinking mouth with respect to the center line of the outer lid main body, thereby improving portability.

  The mounting portion of the outer lid main body is a step formed on the outer peripheral surface of the outer cover main body in the center portion in the direction of the center line of the outer cover main body, and continues downward and parallel to the outer peripheral surface through the step. It has a male screw part formed on the outer peripheral surface, and a packing storage part formed at a corner of the step part and the male screw part, and the length in the diameter direction of the step part is the opening thickness of the beverage container. In this case, the outer peripheral surface portion where the lid and the container main body are connected is continuous and flush with each other, providing a sense of unity of the container and being excellent in design.

  The beverage container is preferably a tumbler. Thus, by implementing the present invention as a tumbler lid, it is possible to provide a lid that does not leak liquid with a simple configuration. Therefore, a tumbler with a lid having a drinking mouth can be provided at low cost.

  The lid of the beverage container according to the present invention has a simple structure to reliably prevent leakage of drinking liquid, and can finely adjust the outflow amount when drinking, and separate and wash each part when washing Can do.

It is a perspective view which shows the container for drinks of the state which attached the lid | cover, and has shown the drinkable state in which the inner cover is an open position. It is the longitudinal cross-sectional view, and has shown the state by which a drink liquid is sealed with an inner cover closed position. It is a perspective view which decomposes | disassembles and shows the container for drinks. It is the expanded longitudinal cross-sectional view which shows an outer cover. It is the expanded side view which shows an outer cover. It is the expanded longitudinal cross-sectional view which shows an inner cover. It is the expanded side view which shows an inner cover. It is the expanded longitudinal cross-sectional view which shows the state which an inner lid is an open position and can drink.

  As shown in FIGS. 1 and 2, the lid 10 of the present invention is attached to an opening 12 a of a container body (tumbler) 12. The lid 10 and the container body 12 constitute a beverage container 14.

  As shown in FIG. 2, the container body 12 has a double structure including a cup-shaped outer body 16 and an inner body 18. A printing sheet (not shown) is placed in the cavity 20 between them as necessary to form a pattern of the container body 12. The exterior body 16 and the interior body 18 are molded products made of synthetic resin, and in this embodiment, molded using a transparent synthetic resin. And the exterior body 16 and the interior body 18 are integrated by putting the interior body 18 in the exterior body 16 and screwing and rotating the lower female screw portion 22 and the male screw portion 24. At this time, the packing 28 is inserted between the upper end surface of the exterior body 16 and the folded portion 26 of the interior body 18 to maintain airtightness. The contact portion between the outer peripheral surface of the upper end portion of the exterior body 16 and the inner peripheral surface of the folded portion 26 of the interior body 18 is welded or bonded as necessary. An internal thread portion 30 is formed on the inner peripheral surface of the opening 12 a of the container body 12. The exterior body 16 and the interior body 18 are transparent, but may be translucent or opaque. In addition, one or both of the exterior body 16 and the interior body 18 may be made of metal such as aluminum or stainless steel in addition to the synthetic resin.

  As shown in FIG. 3, the lid 10 of the present invention includes an outer lid 32 and an inner lid 34. The outer lid 32 and the inner lid 34 are molded products made of synthetic resin.

  As shown in FIGS. 4 and 5, the outer lid 32 includes a cylindrical outer lid body 42 having a mounting portion 36, a female screw portion 38, and an outer edge portion 40. A male screw portion 46 is formed at the lower part of the outer peripheral surface of the outer lid main body 42 via an outer stepped portion 44, and a female screw portion 38 is formed at the lower portion of the inner peripheral surface via an inner stepped portion 48. An O-ring 52 as a packing is fitted to a corner portion where the outer stepped portion 44 and the male screw portion 46 are connected.

  The length of the outer step portion 44 in the outer lid main body diameter direction is the same as the thickness of the upper end portion of the container main body 12, as shown in FIG. Thereby, when the outer lid 32 is attached to the opening 12 a of the container body 12, the outer peripheral surface 12 b of the container main body 12 and the outer peripheral surface 32 a of the outer lid 32 are flush with each other. The attachment of the outer lid 32 to the container body 12 is not limited to the above-described form, and may be an attachment structure in which the container body 12 has a male screw portion and the outer lid 32 has a female screw portion. In addition to the mounting structure using screws, the fixing means such as adhesion or welding may be used, or the locking means may be used for claw coupling.

  As shown in FIG. 4, an outer edge portion 40 extends upward above the outer stepped portion 44. The outer edge portion 40 is a point-symmetrical position 180 degrees away from the center line CL of the outer lid main body 42, and has a drinking mouth portion 54 on one side and a strap attachment portion 56 on the other side. The drinking mouth portion 54 is formed higher than the strap attachment portion 56 so that the beverage liquid can be easily taken. In addition, by setting the strap attaching portion 56, which is the edge portion on the opposite side to the drinking mouth portion 54, in this manner, the nose does not hit when drinking and the usability is improved. A strap attachment hole 58 is formed in the strap attachment portion 56. A strap (not shown) is passed through the strap attachment hole 58 so as to be convenient for carrying.

  The inner peripheral surface 40a of the outer edge portion 40 is formed in a tapered shape that gradually expands upward. In particular, the mouth part 54 is formed so that the thickness gradually decreases toward the upper end, so that the mouth feel is improved during drinking. In addition, the tapered inner peripheral surface 40a has a concave shape that curves inward in the longitudinal section of the outer edge portion 40 that passes through the center line CL of the outer lid main body 42. Therefore, it is possible to prevent the liquid from flowing out into the mouth rapidly and at a time due to a time lag when the liquid flows into the mouth.

  The female screw portion 38 is for screwing the male screw portion 60 (see FIG. 7) of the inner lid 34. A tapered packing contact surface 62 is formed between the female screw portion 38 and the outer peripheral inner peripheral surface 40a.

  As shown in FIGS. 6 and 7, the inner lid 34 includes a bottomed cylindrical inner lid body 74 having a male screw portion 60, a packing holding portion 66, an outlet 68, a bottom plate portion 70, and a knob portion 72. ing. The bottom plate portion 70 is formed near the lower end of the inner lid main body 74, and the upper surface 70b of the inner lid 34 is recessed so that the nose does not hit when seen from above when viewed from above.

  A male screw portion 60 is formed at the lower portion of the outer peripheral surface of the inner lid main body 74. As shown in FIGS. 2 and 3, the male screw portion 60 is screwed into the female screw portion 38 of the outer lid 32. The inner lid 34 is fastened to the outer lid 32 by rotating the inner lid 34 clockwise.

  As shown in FIG. 6, a packing holding portion 66 is formed on the outer peripheral surface of the inner lid main body 74 at the upper portion. The packing holding part 66 includes a tapered surface 76 and a packing holding groove 78. The tapered surface 76 is formed so as to gradually expand upward from the outer peripheral surface 74a where the male screw portion 60 is formed. In addition, a packing holding groove 78 is formed in the circumferential direction on the tapered surface 76. An O-ring 80 as a packing is fitted in the packing holding groove 78.

  The packing holding groove 78 has an overhang portion 82 whose upper portion protrudes outward so that the O-ring 80 does not fall off when the inner lid 34 is screwed into the outer lid 32 and tightened. The O-ring 80 is firmly held by the overhang portion 82. Therefore, as shown in FIG. 2, even if the inner lid 34 is firmly tightened to the outer lid 32, the O-ring 80 does not fall off, and the opening between the packing holding portion 66 and the packing contact surface 62 of the outer lid 32 is eliminated. The ring 80 is crushed and deformed, and the gap between the outer lid 32 and the inner lid 34 can be closed in a watertight manner.

  The packing contact surface 62 and the tapered surface 76 are set so as to have an intersecting angle of 30 ° to 60 °, more preferably an intersecting angle of 40 ° to 50 ° with respect to the center line CL of the outer lid main body 42. Is preferred. Thereby, when the inner lid 34 is tightened to the outer lid 32 by screwing with the female screw portion 38 and the male screw portion 60, the O-ring 80 is reliably deformed between the packing contact surface 62 and the packing holding portion 66, A watertight state can be maintained firmly.

  As shown in FIGS. 6 and 7, the outflow ports 68 are formed side by side in the circumferential direction on the outer peripheral surface 74 a between the male screw portion 60 and the packing holding portion 66 of the inner lid 34. The outflow port 68 is formed from a rectangular through-hole penetrating the inner lid body 74 between the outer peripheral surface 74a and the inner peripheral surface 74b. The outlet 68 is formed at a position adjacent to or adjacent to the O-ring 80 of the packing holding portion 66. Thereby, the liquid in the container main body 12 can be surely flowed out even with a slight upward displacement with respect to the outer lid 32 due to the rotation of the inner lid 34. Therefore, the inner lid 34 can be reliably opened with a small amount of rotation. Moreover, the inner lid 34 can be reliably set to the closed position by rotating the inner lid 34 reversely from the open state and tightening it to the outer lid 32. As shown in FIG. 6, the bottom plate portion 70 has a tapered surface 70 a in the vicinity of the inner lid main body 74 so as not to block the outflow port 68, so that the drinking liquid flows smoothly to the outflow port 68. It has become.

  In addition, although the outflow port 68 was formed in the rectangular shape long in the circumferential direction, it is not limited to this shape, It is good also as a round, a triangle, an ellipse, and other various shapes. However, by making the outflow port 68 into a rectangular shape that is long in the circumferential direction, it is possible to make the inner lid 34 compact in the height direction while securing a constant outflow amount.

  As shown in FIGS. 3, 6, and 7, the knob portion 72 is formed so as to protrude upward from the upper surface 70 b of the bottom plate portion 70 and inward from the upper inner peripheral surface 74 c of the inner lid main body 74. ing. In addition, the knob | pick part 72 should just be a shape which can pick and rotate the inner lid 34 with a finger | toe, and is not limited to the thing of illustration. Further, the position where the knob portion 72 is formed can be formed to protrude upward from the upper surface 70 b of the bottom plate portion 70, or can be formed to protrude inward from the upper inner peripheral surface 74 c of the inner lid main body 74.

  The knob portion 72 extends in the diametrical direction of the inner lid main body 74 and spans between the upper inner peripheral surfaces 74c, and includes a dent portion 72a whose central portion in the diametrical direction is lowered. As shown in FIG. 2, when the inner lid body 74 is tightened in a state of being attached to the outer lid body 42 and is connected to the outer lid 32 in a watertight manner by the O-ring 80, The knob part 72 and the male screw part 60 or the knob part 72 and the female screw part 38 are positioned so that the knob part 72 is parallel to the straight line L1 that passes through the mouth part 54 and is orthogonal to the center line CL of the outer lid body. It is prescribed.

  As shown in FIG. 1, the diameter of the knob 72 when the knob 72 is perpendicular to the straight line L <b> 1 that passes through the mouthpiece 54 and is orthogonal to the outer lid main body center line CL. Open marks 84 and 85 are respectively formed at one end portion in the direction and at a position where the one end portion is located at the outer edge portion 40. The open marks 84 and 85 are formed of circular recesses, but may be any marks that are identifiable in an arrow, a straight groove, or other shapes. The state in which the open marks 84 and 85 are close to each other (see FIG. 1) indicates the open state of the inner lid 34, and it can be seen at a glance that the liquid can be drunk. Therefore, when carrying, by grasping the positional relationship of the knob portion 72, it is possible to know whether it is a drinking enabled state in the open position or a drinking disabled / portable state in the closed position. Therefore, it is possible to prevent the liquid from being accidentally spilled when being carried.

  As shown in FIGS. 6 and 7, the outlet 68 is not formed on the peripheral surface of the inner lid main body 74 where both ends of the knob 72 are located. This maintains the strength of the inner lid main body 74, and even if the outlet 68 is formed at this position, as described above, it is difficult to swallow the liquid due to the positional relationship between the drinking mouth portion 54 and the knob portion 72 shown in FIG. It is because it is not necessary to let it flow out. However, the outlet 68 is not limited to this form, and may be formed over the entire circumference without providing the discontinuity of the outlet 68 in the circumferential direction.

  As shown in FIG. 1, on the upper surface 70 b of the bottom plate portion 70, an arrow 86 indicating the rotation direction of the inner lid 34 and a state change of the inner lid 34 when the inner lid 34 is rotated in the direction indicated by the arrow 86 are shown. The “close” character 87 shown is formed by projecting from the upper surface 70 b, thereby forming an uneven step. In addition, an arrow pointing in the opposite direction to that of the drawing and a letter “open” may be formed protrudingly adjacent to the arrow, or those two arrows and letters may be indicated. It may be.

  In use, as shown in FIG. 3, the external screw 32 of the outer lid 32 is screwed into the female screw 30 of the container body 12 and rotated in the clockwise direction. It is attached to the container body 12. When the outer lid 32 is tightened, as shown in FIG. 2, the O-ring 80 fitted on the outer lid 32 is deformed and comes into water-tight contact with both, so the outer lid 32 is attached to the container body 12 in a water-tight manner. be able to.

  After the potable liquid such as coffee is stored in the container body 12, the inner screw 34 is screwed into the female screw part 46 of the outer lid 32 and rotated in the clockwise direction, whereby the inner lid 34 is rotated in the clockwise direction. Attach to. When the inner lid 34 is tightened, as shown in FIG. 2, the O-ring 80 is crushed by the packing contact surface 62, and further tightening becomes impossible. This state is a closed state, and the knob portion 72 is parallel to the straight line L1 passing through the drinking mouth portion 54 and orthogonal to the center line CL of the outer lid main body. In this state, since the knob portion 72 is close to the drinking mouth portion 54, when the user tries to drink, the upper lip touches the knob portion 72 so that the user can know that the mouth portion is closed. .

  By rotating the inner lid 34 counterclockwise, the inner lid 34 is displaced upward in the outer lid 32 as shown in FIG. This displacement creates a gap 90 between the O-ring 80 of the inner lid 34 and the packing contact surface 62. By tilting the container body 12, the liquid in the container body 12 flows out from the outlet 68 into the inner peripheral surface of the outer edge portion of the outer lid 32, and drinks the drinking liquid in the container body 12 through the drinking mouth part 54. Can do. By changing the amount of rotation of the inner lid 34, the amount of drinking liquid flowing out can be adjusted to the degree of opening of the outlet 68 and the degree of clearance between the O-ring 80 and the packing contact surface 62. The outflow amount can be set easily.

  After use, the lid 10 itself is removed from the container main body 12 as shown in FIG. 2, and the lid 10 can also be easily separated by unscrewing the outer lid 32 and the inner lid 34. It is easy, and there is no inconvenience that it is difficult to carry out cleaning, which is likely to occur in a conventional slide type or swing type inner plug.

  In the above embodiment, the material of the lid 10 has been described by taking synthetic resin as an example, but it may be made of metal such as stainless steel or aluminum. In the above-described embodiment, the outer lid 32 and the inner lid 34 are arranged on the same center line CL and are concentrically arranged. However, the inner lid 34 is placed with respect to the outer lid 32 so that the mouthpiece 54 side is widened. It may be eccentric.

  In the said embodiment, the said knob | pick part 72 is comprised from the protrusion extended in the diameter direction of the said inner cover main body 74, and was spanned between the internal peripheral surfaces, The center part of the said protrusion in the diameter direction However, it is not limited to this. In particular, in the above-described embodiment, the bottom plate portion 70 is a lower inner peripheral surface 74b of the inner lid main body 74 and extends downward from an upper position of the outlet 68 so as to be a lower portion of the inner lid main body 74. Therefore, the knob 72 can be formed at a low position in the inner lid 34. When a person with a normal nose height is used, the tip of the nose rarely hits the knob 72. Because. Therefore, the arbitrarily shaped knob 72 can be formed. For example, it may have a shape in which the central portion is not recessed, a mountain shape in which the central portion is raised, or an arbitrary shape that has the shape of an animal. Further, the shape and quantity of the knob portion 72 itself are not limited as long as the knob can be rotated by putting a finger on it in addition to the long protrusion in the diameter direction of the inner lid 34. For example, in addition to a single character shape, it may be a trident, a cross, or other various shapes.

  As shown in FIG. 2, when the inner lid 34 is tightened in a state of being attached to the outer lid 32, and both are water-tightly coupled by an O-ring 80, the outer lid passes through the drinking mouth portion 54 and the outer lid 34. Although the knob 72 is formed on the inner lid 34 so that the knob 72 is parallel to the straight line L1 orthogonal to the center line CL of the lid 32, the present invention is not limited to this. As described above, in the above embodiment, the bottom plate portion 70 is a lower inner peripheral surface of the inner lid 34 and extends downward from an upper position of the outlet 68 (see FIG. 6). Since it is located at the lower part of the inner lid 34, the knob portion 72 can be formed at a lower position in the inner lid 34. In normal use, when the lip is applied to the drinking mouth portion 54, This is because the upper lip rarely hits the knob of the inner lid 34. For the same reason, it is not necessary to attach the knob to the inner lid body so that the knob made of ridges is at a position perpendicular to a straight line that passes through the drinking port and is perpendicular to the center line of the outer lid body.

  However, when the inner lid 34 is closed, the height difference between the outer lid 32 and the drinking mouth portion 54 is low, and the upper lip touches the upper end portion of the knob portion 72 when the mouth is put on the drinking mouth portion 54. In the case of the positional relationship, the above-described positional relationship allows the upper lip to touch the knob 72 of the inner lid 34 in the closed position. As a result, when the user touches the mouthpiece 54 with the inner lid 34 closed, the upper lip touches the knob 72, so that the inner lid 34 can be known from the lip feel. Convenient. In this case, the knob portion 72 is formed on the inner lid 34 so that the knob portion 72 made of a protrusion further passes through the drinking mouth portion 54 and is orthogonal to the straight line L1 orthogonal to the center line CL of the outer lid 32. By forming and denting the center of the knob 72, the tip of the nose can be prevented from hitting the knob 72 when a person with a high nose is used.

  As shown in FIG. 1, one end in the diameter direction of the knob 72 at a position where the knob 72 is perpendicular to the straight line L <b> 1 passing through the mouthpiece 54 and orthogonal to the center line CL of the outer lid 32. And open marks 84 and 85 at one end portion of the outer edge portion 40. Thus, when the open marks 84 and 85 are brought close to each other, it can be seen at a glance that the inner lid 34 is in the open state. Therefore, it is avoided that the inner lid 34 is accidentally carried in the open position. Further, at the position where the open marks 84 and 85 are close to each other, the knob portion 72 is at a position 90 ° away from the drinking mouth portion 54, so that the outer edge portion 40 and the knob portion 72 that the upper lip hits when the inner lid is closed are disposed. In the case of a lid in a positional relationship, the upper lip does not hit the knob 72 and can be easily drunk.

  Further, by providing the open marks 84 and 85, if the inner lid 34 is rotated beyond the open marks 84 and 85, the inner lid 34 may be removed. It is convenient because it is possible to easily know the positional relationship where the inner lid 34 comes off due to the presence. In the present embodiment, the internal thread portion 46 of the outer lid 32 and the external thread portion 60 of the inner lid 34 have a pitch and a screw length that can be removed by 2.5 rotations. Although the open marks 84 and 85 are close to each other when the inner lid 34 is completely rotated 90 degrees from the closed state, the present invention is not limited to this.
