Description

  The present invention includes a bottle body and a plug body that is attached to the upper end of the bottle body so that a beverage from the bottle body can be guided directly to the drinking mouth and can be directly drunk, the drinking mouth on the top plate portion of the stopper body It is related with the direct drinking bottle which was made to hold | maintain selectively in the drinking position which protruded in the inside, and the storage position which makes the protrusion degree from a top-plate part small or accommodates in a stopper.

Such direct drinking bottles are already known (see, for example, Patent Documents 1 and 2). Such a direct drinking bottle can be made easy to handle by holding it in the retracted position while keeping the drinking mouth in the drinking position protruding from the top plate portion of the stopper, and making it easy to handle in a bulky manner. There is an advantage over the drinking mouth of the fixed structure as known in Patent Documents 3 and 4.

  However, the ones described in Patent Documents 1 and 2 have a complicated structure in which the stopper has a large number of parts in order to selectively hold the drinking mouth at the drinking position and the storage position. In particular, the one described in Patent Document 1 is not a sucking and drinking method using a straw as described in Patent Document 2, so that it is formed on the stopper in conjunction with switching the drinking mouth between the use position and the storage position. It is necessary to open and close the stopper passage to the drinking mouth, and the stopper structure is more complicated. For this reason, the cost can not be reduced and the plug part is heavy and bulky, and recently, the user's selection is fixed slightly at the drinking position as described in Patent Documents 3 and 4, Shifting to a light and low-cost one with a simple structure, including simple closing of the mouthpiece with a single-open lid that covers the mouthpiece with a good appearance, and contributing to environmental ecology through the use of my bottles.

  However, the one described in Patent Document 3 is the simplest one in which the plug body a has a single structure as shown in FIG. 3, but in the case of cold use, the inside and the outside of the single wall of the plug body a. There is a problem in that dew condensation occurs on the outer surface of the base part of the top plate part b and the mouthpiece c and the dew condensation surface is exposed when the one-sided lid is opened, so that the touched part gets wet. In order to avoid this, if the dew condensation occurs when the one-sided lid d is opened, there is no choice but to clean it.

  Moreover, since the thing of patent document 4 has a double wall structure from the part which the drinking mouth of the plug body protrudes, there is no dew condensation on the outer surface of the top plate part of the plug body. Since the main body portion of the plug body from which the mouth protrudes needs to have a double structure independent of the protrusion portion of the drinking mouth, the structure is complicated and expensive compared to the one described in Patent Document 1, and the weight is also increased. Further, dew condensation on the outer surface of the inner wall of the double wall of the main body of the plug body cannot be prevented, and there is no exposure of the dew condensation surface to the outside, but long-term retention of the dew condensation water has problems such as propagation of various bacteria, so that Patent Document 4 It is necessary to disassemble the double wall part of the main body of the plug body so that it can be cared for as in the structure described in, both for disassembly care and reassembly and reuse. Inconvenient.

  Therefore, the present inventor has developed a technology that can solve different problems that are incompatible with those described in Patent Documents 3 and 4.

  Based on such development, the present invention provides a direct drinking bottle with a simple structure, light weight, and low cost, in which the dew condensation surface at the time of cold insulation is not exposed to the outside, and maintenance of the dew condensation water is unnecessary. This is the issue.

  In order to solve the above problems, a direct drinking bottle of the present invention includes a bottle body and a stopper body that is attached to the upper end of the bottle body so as to guide the beverage from the bottle body to the drinking mouth and allow direct drinking. The drinking port is a direct drinking bottle that is selectively held at a drinking position that protrudes on the top plate portion of the plug body and a storage position that reduces the degree of protrusion from the top plate portion or accommodates in the plug body. The stopper is inserted into the mouth of the bottle body from the top plate portion, and is sealed with a sealing member between the outer periphery of the lower end opening and the inner wall of the mouth, and the lower end opening communicates with the inside of the bottle. The drinking mouth has a valve portion that directly closes the lower end opening of the inner stopper portion via a seal member in the retracted position and opens the lower end opening of the inner stopper portion in the drinking position, and in the drinking position. It has a bypass path that leads to the bottle body avoiding the valve part

  According to the above configuration, the stopper body has a drinking mouth that can be directly taken, and the inner stopper portion enters the mouth portion of the bottle body, and is sealed between the outer wall of the lower end opening and the inner wall of the mouth portion by the sealing member. The lower end of the bottle leads to the inside of the bottle so that the beverage in the bottle can be guided and directly taken without leaking into the drinking mouth, but the drinking mouth protrudes above the top plate of the plug body and is easy to drink directly. Taking advantage of the two positions of the drinking position and the protruding position or the retracted position stored in the stopper body, the drinking mouth at the retracted position enters the inner plug portion and directly into its lower end. Since the holding valve part closes the lower end opening of the inner plug part, the area where the single wall separates the inside of the bottle and the space inside the inner plug part and the dew is formed on the outer surface, the outer surface of the valve part of the drinking mouth and the vicinity thereof, In addition, the area around the outer surface of the lower part of the inner plug is restricted to a certain extent and beyond The drinking mouth of the drinking position protrudes from the inner plug portion onto the top plate portion of the plug body, and the lower end valve portion is separated upward from the lower end opening of the inner plug portion. As the opening is opened, the dew condensation area is opened as a part of the beverage outflow passage from the lower end opening of the inner plug portion to the drinking mouth, and can be used for direct drinking and maintenance as a beverage passage. , Condensed water will not accumulate enough to leak out.

  In the above, the drinking mouth may be characterized in that a space is formed between the drinking cap and the inner plug portion.

  In such a configuration, in addition to the above, the space between the drinking mouth and the inner stopper portion at the storage position provides thermal insulation between the bottle body and the stopper body top plate. Condensation can be reliably prevented.

  In the above, the drinking mouth can be characterized in that it is elastically held at the drinking position by the biasing force of the elastic member acting between the inner plug portion.

  In such a configuration, in addition to the above, the drinking mouth is automatically protruded to the drinking position by the urging force of the elastic member only by releasing the holding of the drinking position.

  In the above, the elastic member may further be an elastic film member whose outer periphery is supported by the inner plug portion and whose drinking mouth is supported by the inner periphery portion.

  In such a configuration, in addition to the above, the drinking mouth is further supported with a simple support structure by one elastic membrane member whose outer periphery is supported by the inner plug portion so as to give protrusion behavior, and the elastic membrane member Thus, the air convection area in the space between the inner plug portion and the drinking mouth is divided into two inward and outward directions, and the air insulation effect inside and outside can be enhanced. Moreover, since the elastic membrane member seals between the inner plug portion and the drinking mouth, it is possible to prevent the beverage from leaking through the both, and the drinking hole on the top plate portion of the stopper body and the drinking hole Seal packing between the mouth can be omitted.

  In the above, the bypass passage may further include a beverage outlet and an air inlet for introducing outside air into the bottle.

  In such a configuration, in addition to the above, further, the bypass passage leads to the inside of the bottle without being disturbed by the valve portion by bypassing the valve portion from the outflow passage extending straight from the upper end of the drinking mouth to the valve portion. The detour direction for guiding the beverage in the bottle body to the drinking mouth is the forward tilt side of the bottle body during direct drinking, and the detour direction for introducing outside air into the bottle body is the bottle body during direct drinking By providing each separately corresponding to the direction opposite to the forward tilt side, direct drinking of the beverage and introduction of the outside air associated therewith can be smoothly achieved without interfering with each other.

  In the above, further, a closed position covering the top plate portion of the plug body around the hinge connecting portion to the top plate portion one side of the plug body, a single-opening lid retracting from the closed position, and the single-opening lid closed position The single-open lid holds the drinking mouth in the retracted position in the closed position, and closes the upper end opening of the drinking mouth via the seal member. Can be characterized.

  According to such a configuration, in addition to the above, the mouthpiece is further closed by a closing operation using a one-sided lid that adjusts the appearance when the mouthpiece is in the storage position and the lock mechanism to the closed position. Is set to the storage position against the protruding behavior and can be held in the storage position by locking to the closed position. In addition, since the single-open lid closes the upper end opening of the drinking mouth via the sealing member at the closed position, the inside of the drinking mouth also becomes an air heat insulating part together with the space between the mouth part of the bottle body and the inner plug part, and the bottle body is kept warm. In the unlikely event that a drink remains in the mouth, it will not leak out.

  Further features of the present invention will become apparent from the following specific description and drawings. Each feature of the present invention can be used alone or in combination with various combinations.

  According to the direct drinking bottle of the present invention, the stopper is inserted into the inner plug portion of the drinking mouth itself so as to be able to guide and drink the beverage in the bottle without leaking to the drinking mouth, and the storage position where the drinking mouth itself is lowered. In addition to closing the lower end opening of the inner plug portion at the lower end valve portion to prevent the beverage from flowing out, the condensation area during cold storage is defined as the outer surface of the valve portion of the drinking mouth and its vicinity and the lower portion of the inner plug portion. It is possible to prevent the influence of the dew condensation water to the outside by regulating the vicinity of the outer surface and a small range. In addition to opening the lower end opening of the inner stopper to enable direct drinking by the outflow of the beverage by moving the drinking mouth to the drinking position where it is easy to drink directly, As a part, the dew condensation area can be opened and used for direct drinking and maintenance as a normal beverage passage that does not require disassembly or reassembly. Moreover, it is realized by a simple combination of a stopper structure of an inner stopper portion and a movable drinking mouth, so that the structure is simple and is not bulky, and is lightweight and low-cost.

  In addition to the above, the space between the drinking mouth and the inner stopper at the storage position is used for air insulation between the bottle body and the stopper top plate to ensure that condensation forms on the stopper top plate. Can be prevented.

  In addition to the above, the drinking mouth is automatically protruded to the drinking position simply by releasing the holding position by the biasing force applied by the elastic member.

  In addition to the above, the drinking mouth is supported by a simple support structure with one elastic membrane member whose outer periphery is supported by the inner plug portion so as to give a protrusion habit, and the inner membrane portion and the drinking portion are supported by the elastic membrane member. The air convection area in the space between the mouth and the inside can be divided into inside and outside to enhance the inside and outside air insulation effect. Moreover, since the elastic membrane member seals between the inner plug portion and the drinking mouth, it is possible to prevent the beverage from leaking through the both, and the drinking hole on the top plate portion of the stopper body and the drinking hole Seal packing between the mouth can be omitted.

  In addition to the above, the bypass passage can be led to the inside of the bottle without obstruction of the valve portion by bypassing the valve portion from the outflow passage extending straight from the upper end of the drinking mouth to the valve portion. The detour direction for guiding the beverage in the body to the drinking mouth is the forward tilt side of the bottle body when drinking directly, and the detour direction for introducing outside air into the bottle body is opposite to the forward tilt side of the bottle body when drinking directly By providing each individually correspondingly, it is possible to smoothly achieve the direct drinking of the beverage and the introduction of the outside air associated therewith without interfering with each other.

  In the above, further, a closed position covering the top plate portion of the plug body around the hinge connecting portion to the top plate portion one side of the plug body, a single-opening lid retracting from the closed position, and the single-opening lid closed position The single-open lid holds the drinking mouth in the retracted position in the closed position, and closes the upper end opening of the drinking mouth via the seal member. Can be characterized.

  In addition to the above, using a one-sided lid that adjusts the appearance when the drinking mouth is in the retracted position and locking to the closing position by its locking mechanism, the drinking mouth resists its protruding behavior by closing operation. The storage position is set, and the storage position can be held by the lock to the closed position. In addition, since the single-open lid closes the upper end opening of the drinking mouth via the sealing member at the closed position, the inside of the drinking mouth also becomes an air heat insulating part together with the space between the mouth part of the bottle body and the inner plug part, and the bottle body is kept warm. In the unlikely event that a drink remains in the mouth, it will not leak out.

  Hereinafter, the direct drinking bottle of the present invention will be described in detail based on the embodiment shown in FIGS.

  As shown in FIG. 1, the direct drinking bottle of the present embodiment includes a bottle body 1 composed of a vacuum double container having a vacuum heat insulating space 2 between an inner wall and an outer wall made of stainless steel, and a mouth portion 1 a of the bottle body 1. A bottle body 20 is formed by a synthetic resin plug body 5 that has a female thread that is threadedly engaged with a male thread 3 formed on the outer wall of the bottle body 1. The bottle main body 20 has one end of the upper end portion, specifically, the back surface side of the top plate portion 5a of the plug body 5, and the upper end portion of the bottle main body 20 with the hinge connecting portion 10 by the rotation shaft 6 as the center. As shown in FIG. 1 (a), there is provided a synthetic resin one-sided lid 7 that closes and closes the drinking mouth 14 for direct drinking and is opened and closed as shown in FIG. 1 (b). ing. However, the bottle body 20 can be freely designed with or without heat insulation, made of metal or non-metal, with or without the single lid 7, and the material, and the specific structure is not particularly limited. A locking mechanism 8 is provided between the single-opening lid 7 and the bottle body 20 to lock the single-opening lid 7 in a closed state and to release the lock.

  The bottle body 1 in the illustrated example has a body portion 1b that is slim enough to be held by one hand, and the upper portion of the body portion 1b is formed to have substantially the same diameter as the plug body 5 attached to the mouth portion 1a. Yes. Holding the barrel portion 1b and the plug body 5 of the bottle body 1 with one hand, the operation of the lock mechanism 8 with the finger of the hand held by one hand, the opening operation of the single-open lid 7 associated therewith, and the single-open lid 7 The shape is such that it is easy to perform a direct drinking operation with the drinking mouth 14 after opening. The single-open lid 7 in the illustrated example is biased in the opening direction by a vine spring 131 mounted around the rotation shaft 6. Therefore, the locking mechanism 8 of the single-open lid 7 is locked to the closed position against the bias of the vine spring 131. When this lock is released, the single-open lid 7 is urged by the vine spring 131. Will be opened automatically. Such urging in the opening direction may be replaced by an elastic body provided around the drinking mouth 14 of the bottle body 20 or a seal packing 16 having elasticity for sealing the drinking mouth 14 provided on the one-sided lid 7. it can.

  The plug body 5 includes a substantially cylindrical outer plug portion 51 that is screwed into the male screw 3 of the mouth portion 1a of the bottle body 1 and covers the mouth portion 1a, and a top plate portion 5a of the plug body 5 to the inside of the mouth portion 1a. The lower end opening 52a is sealed between the inner wall of the mouth portion 1a and the inner wall of the mouth portion 1a by the seal packing 9 so that the lower end opening 52a communicates with the inside of the bottle body 1. 1 (b), a drinking position protruding on the top plate portion 5a of the plug body 5, and a storage position for reducing the degree of protrusion from the top plate portion 5a shown in FIG. 1a, the lower end opening 52a of the inner stopper 52 is closed via the seal packing 141 in the retracted position shown in FIG. 1A, and the drinking position shown in FIG. Directly holding the valve portion 142 that opens the lower end opening 52a of the inner plug portion 52, and avoids the valve portion 142 in the drinking position. It is assumed that having a bypass passage 143 leading to the bottle body 1 Te. Here, the drinking port 14 can be held at the drinking position and the storage position by any method.

  Thereby, the plug body 5 has the drinking mouth 14 that can be directly taken, and the inner plug portion 52 enters the mouth portion 1a of the bottle body 1 and extends between the outer wall of the lower end opening 52a and the inner wall of the mouth portion 1a. It is sealed by the seal packing 9 so that the lower end opening 52a leads into the bottle body 1, and the beverage in the bottle body 1 can be guided and directly drinked without leaking to the drinking mouth 14. In particular, the drinking position in FIG. 1 (b) is easy to drink directly because the drinking mouth 14 protrudes on the top plate part 5 a of the plug 5, and FIG. 1 (FIG. Utilizing the fact that the two positions of the storage position of a) can be taken, the drinking mouth 14 at the storage position enters into the inner plug portion 52 as shown in FIG. The closed valve portion 142 closes the lower end opening 52 a of the inner plug portion 52, so that the region where the single wall separates the inside of the bottle body 1 and the space within the inner plug portion 52 and the dew condensation is formed on the outer surface is the valve of the drinking mouth 14. It is possible to control the degree of the outer surface of the portion 142 and the vicinity thereof, and the vicinity of the lower outer surface of the inner plug portion 52, and prevent dew condensation in a range beyond that. Further, as shown in FIG. 1B, the drinking mouth 14 at the drinking position protrudes from the inner plug portion 52 onto the top plate portion 5 a of the plug body 5, and the lower valve portion 142 is the lower end portion of the inner plug portion 52. With the opening of the lower end opening 52a away from the opening 52a, the condensation region is opened as a part of the beverage outflow passage extending from the lower end opening 52a of the inner plug portion 52 to the drinking mouth 14, It can be used for care as a beverage passage, and the condensed water will not accumulate as it leaks to the outside.

  As a result, the stopper 5 can be introduced into the inner stopper portion 52 of the drinking mouth 14 itself so that the beverage in the bottle 1 does not leak into the drinking mouth 14 and can be directly taken. , The valve portion 142 at the lower end closes the lower end opening 52a of the inner plug portion 52 to prevent the beverage from flowing out. The influence on the outside of the dew condensation water can be prevented by restricting the vicinity of the lower outer surface of the inner plug portion 52 to a small range. In addition, the movement of the drinking mouth 14 itself to the drinking position where it protrudes easily allows the lower end opening 52a of the inner stopper 52 to be opened so that the beverage can be directly taken out. As a part of the passage, the dew condensation area is opened and used for direct drinking and maintenance as a normal beverage passage that does not require disassembly or reassembly, and does not accumulate condensed water. In addition, it is realized by a simple combination of a stopper structure of the inner stopper portion 52 and the movable drinking mouth 14, and the structure is simple and does not become bulky.

  It should be noted that the outer plug portion 51 of the plug body 5 is suitable for externally attaching and detaching the outer periphery of the mouth portion 1a of the bottle body 1 having a metal vacuum double structure, and the inner plug portion 52 has a drinking mouth 14. It is suitable for the direct drinking of beverages using the bottle and the closing of the mouth portion 1a when the drinking mouth 14 is stored. The inner plug portion 52 is fitted with a seal packing 9 in a groove 52b formed on the outer periphery of the lower end opening 52a, and is pressure-bonded from above to an upward stepped portion 1b1 formed on the inner peripheral base portion of the mouth portion 1a to seal each other. Heat and beverage are prevented from leaking through the gap between the mouth portion 1a and the inner plug portion 52. Further, the lower end opening 52a is formed in an upward valve port, and the seal packing 141 of the valve unit 142 of the drinking port 14 in the retracted position is securely pressed and closed from above, and heat is transmitted through the gap at the lower end opening 52a. Prevents beverages from leaking out. In order to improve the sealing performance by the seal packing 141, a pressure bonding portion with the lower end opening 52a of the valve port mold is used as a seal lip 141a to easily absorb a dimensional error, a molding error, and an assembly error between the pressure bonding. In addition, since the drinking mouth 14 appears and disappears in the linear direction, the appearance structure is simplified, and the drinking mouth 14 appears and disappears on the axis of the bottle body 1, so that the stopper body 5 and the drinking mouth 14 are concentric with the bottle body 1 and all parts are concentric circles. As a result, the production of the mold becomes easy and the cost can be reduced in this respect as well.

  Further, as shown in FIG. 1 (a), the drinking mouth 14 can form a space 53 with the inner plug portion 52 at the storage position. The space 53 between the inner plug portion 52 air-insulates the inside of the bottle body 1 and the top plate portion 5 a of the plug body 5, so that it is ensured that condensation forms on the top plate portion 5 a of the plug body 5. Can be prevented. The bypass passage 143 can be led into the bottle body 1 without obstruction of the valve section by bypassing the valve section from the outflow passage extending straight from the upper end of the drinking mouth 14 to the valve section. The detour direction for guiding the beverage in 1 to the drinking mouth 14 is the forward tilt side of the bottle body 1 when directly drinking, and the detour direction for introducing outside air into the bottle body 1 is the bottle body 1 when directly drinking In response to the reverse direction of the forward tilt side, the forward tilt side detour 143a and the anti-front tilt side detour 143b are individually provided so that the direct drinking of the beverage and the introduction of the outside air can be smoothly performed without interfering with each other. Can be achieved.

  Furthermore, the drinking mouth 14 is elastically held at the drinking position by the urging force of the elastic member 54 acting between the inner plug portion 52. Thereby, the drinking mouth 14 is automatically protruded to the drinking position shown in FIG. 1B by the urging force of the elastic member 54 only by releasing the holding in the storage position shown in FIG. Moreover, the drinking mouth 14 is pushed against the urging force of the elastic member 54 from the drinking position shown in FIG. 1B to the storage position shown in FIG. The mouthpiece 14 is automatically held in the retracted position by automatically locking the single-open lid 7 in the closed position. Accordingly, since the drinking mouth 14 is set to the drinking position simultaneously with the automatic opening of the one-sided lid 7 by releasing the lock of the one-sided lid 7 to the closed position, it is possible to drink directly. Further, at the same time when the single-open lid 7 is closed, the drinking mouth 14 is automatically set to the storage position, and the automatic lock to the closed position of the single-open lid 7 ensures the storage position and the sealed state of the mouth portion 1a. Since it is maintained, there is an advantage that the one-sided bottle with a fixed drinking mouth disclosed in Patent Documents 3 and 4 and the usability and labor are not particularly changed. In addition, since the single lid 7 closes the upper end opening 14a of the drinking mouth 14 via the seal packing 16 at the closed position, the inside of the drinking mouth 14 also becomes an air heat insulating portion together with the space 53, thereby improving the heat retaining property of the bottle body 1 and Even if a beverage remains in the mouth 14, it does not leak out.

  The seal packing 141 is attached to the outer periphery of the valve portion 142 that forms the bottom wall of the drinking mouth 14, but can also be attached to the lower end opening 52 a of the inner stopper portion 52, so that the drinking mouth 14 runs out of water after direct drinking. It is easy to make it an advantageous form. In order to drain the water, it is effective to incline the upper surface of the valve portion 142 of the drinking mouth 14 as shown in FIG. 1B, and even if the drinking mouth 14 is stored immediately after direct drinking, There is an advantage that it is difficult to occur. The seal packing 16 is attached by being elastically fitted to a cylindrical portion 7e integrally formed on the back surface of the single-open lid 7, or is fixed thereto by adhesion or ultrasonic welding. The seal packing 16 may also be provided on the side of the upper end opening 14a of the drinking mouth 14 in terms of the sealing function, but there is a tendency to obstruct direct drinking.

  The elastic member 54 may be various types of springs, but in the illustrated example, the elastic member 54 is an elastic film member whose outer periphery is supported by the inner plug portion 52 and the drinking mouth portion 14 is supported by the inner peripheral portion. As a result, the drinking mouth 14 is supported by a simple support structure with a single elastic membrane member as the elastic member 54 whose outer periphery is supported by the inner plug portion 52, and is provided with an elastic membrane member. The air convection area in the space 53 between the stopper portion 52 and the drinking mouth 14 is divided into two inward and outward directions, so that the inside and outside air insulation effect can be enhanced. In addition, since the elastic membrane member seals between the inner plug portion 52 and the drinking mouth 14, it is possible to prevent the beverage from leaking through the both, and the drinking mouth 14 of the top plate portion 5 a of the stopper body 5 appears and disappears. It is possible to omit the seal packing between the in / out hole 5b and the drinking hole 14.

  In order to support the elastic member 54, the plug body 5 is formed with the outer plug portion 51 and the inner plug portion 52 as separate bodies as shown in FIG. A male screw formed on the outer peripheral upper end of the inner plug portion 52 is screwed into the female screw 55 to integrate both, and the upper end of the inner plug portion 52 and the top plate portion 5a of the plug body 5 integrally formed with the outer plug portion 51 are formed. As shown in FIGS. 1A and 1B, the outer periphery of the elastic membrane member, which is the elastic member 54, is sandwiched and held, and the inner periphery is elastically fitted into the groove 14b formed on the outer periphery of the drinking mouth 14. And support. In order to give the drinking mouth 14 a protrusion habit, the elastic membrane member, which is the elastic member 54, is in a normal state in a state that is obliquely upward from the outer peripheral side to the inner peripheral side shown in FIGS. 1 (b) and 1 (c). Is set to the retracted position, it is elastically deformed to have a downward inclination as shown in FIG. 1A, and the restoring force to the upward inclination is stored. Such reversal of the inclination is suitable for suppressing the amount of expansion / contraction required for responding to the stroke of the mouth 14 of the film-like elastic member 54, and the life of the film-like elastic member 54 can be increased. The film-like elastic member 54 is preferably silicon rubber. An inclined portion 5c is provided on the top plate portion 5a of the plug body 5 in accordance with the upward inclined form of the elastic member 54 so as not to cause a dead space, thereby suppressing bulkiness.

  Here, the lock mechanism 8 is shown in FIGS. 1A to 1C and FIGS. 2A to 2C, and includes an engagement portion 31 that is a lock mechanism fixing portion provided on the bottle body 20 side. When the single-opening lid 7 is normally provided so that the outer surfaces thereof are flush with each other and the single-opening lid 7 is closed, the engaging portion 31 is engaged with the retracting operation from the engaging portion 31 temporarily. And a lock member 32 that is a lock mechanism movable portion that is unlocked by a temporary retraction operation from the outer surface. Thus, the drinking port 14 for direct drinking is covered with the upper end portion of the bottle body 20 around the hinge connecting portion 10 to the upper end portion one side of the bottle body 20 to prevent the outflow of the content liquid. The lock member 32 is disposed between the bottle body 20 and the bottle body 20 with respect to the one-sided lid 7 that opens to the hinge connecting part 10 side so as to open the upper end of the bottle 20 and the drinking mouth 14 so that the drinking mouth 14 can directly drink. When the single-open lid 7 is closed, the lock member 32 is engaged with the engagement portion 31 on the bottle body 20 side with a temporary retracting operation to lock the lock member 32 in a closed state, and the lock member 32 is temporarily closed from the outer surface. The lock is released in response to the retraction operation. A lock member 32 which is a movable part for the lock and unlock is provided on the side of the one-sided lid 7 in the lock mechanism 8 on the bottle body 20 side. Fixed part and Engagement / disengagement of all the engaging portions 31 allows the single-open lid 7 to be locked in the closed state, and the lock can be released, and the sufficient depth and vertical length obtained between the single-open lid 7 and the drinking mouth 14 can be obtained. The dead space S in the directional range is obtained, and the single-open lid 7 and the outer surface are flush with each other and are provided with a sufficient vertical dimension.

  As a result, the drinking mouth 14 for direct drinking is covered and closed together with the upper end portion of the bottle body 20, and the one-sided lid 7 that opens one side so as to open them is locked in the closed state, and the lock is released. In the lock mechanism 8, a lock member 32 that is a movable part is provided on the side of the single-opening lid 7, and the single-opening lid 7 is locked in a closed state by being engaged with and disengaged from the engaging part 31 on the bottle body 20 side.
