The intermediate return portion 30B has a shape that slides on the thread of the bottle and grips the thread of the bottle (preferably without engaging), and the depth of the neck ring is deep with respect to the mouth of the bottle. In the case of a short finish bottle (the depth of the neck ring is shallower than the mouth of the bottle as compared with the long finish bottle), the neck ring can be slid to grip the neck ring.

  All the intermediate return portions 30 </ b> B may have the same relative height with respect to the finger 30, but preferably have a zigzag shape. That is, it is preferable that the height of a part of the intermediate return part 30B is offset with respect to a part of the other intermediate return part 30B. Preferably, every other intermediate return portion 30B is offset in height by the same offset amount or substantially the same offset amount (see FIG. 7).

  The web part 31 or the upper part of the cap member is hollow and has a boss part 32 protruding upward (projecting upward of the web part 31 so as to be separated from the finger part 30). The boss portion 32 is formed adjacent to the surface of the web between the vertical ribs 32B, and has a plurality of discharge openings 32A provided at intervals, so that the liquid and supplement or additive material in the bottle can be It can pass through the opening (details will be described later).

  The cap member 3 is made of polypropylene (PP), polyethylene terephthalate (PET), polyethylene, polystyrene, polycarbonate (PC), styrene, low density polyethylene (LDPE), linear low density polyethylene (LLDPE), acrylonitrile / butadiene / styrene ( It can be made of a plastic material such as ABS) resin, Delrin (registered trademark) (acetal homopolymer) or nylon, and the finger portion 30 is thin (because it is fixed only at the end) and at least partly flexible Have sex.

  In this embodiment, the cap member 3 includes a coupling structure for non-screwingly coupling the cap assembly 1 to a beverage bottle by engagement with a bottle flange or collar and thread or collar or thread. The connection structure includes finger portions 30 and return portions 30A and 30B. With such a connection structure, it is not necessary to match the bottle neck thread, which may vary depending on the beverage vendor and / or bottle type.

  In another embodiment, the number of finger portions 30 can be changed. For example, a smaller number of relatively hard fingers 30 may be used. In another embodiment, the coupling structure is a bottle by sliding over some or all of the threads when the cap assembly 1 is pressed against the neck of the bottle and locking it without rotating along the bottle threads. Finger portions 30 having return portions or teeth that engage the threads of the neck. The cap assembly 1 rotates slightly when the return portion slides on the bottle neck thread, thereby fixing the cap assembly 1 and limiting play between the cap assembly 1 and the bottle. The return portion may engage the thread, but in another embodiment, the return portion preferably engages the neck ring or at least engages the neck ring.

Housing Member As shown in FIG. 10, the supplement or additive housing member 4 is configured to be attached to the web portion 31 of the cap member 3 by, for example, a screw tightening method and / or a snap fitting method. As will be described in detail below, the housing member 4 forms an outer peripheral portion of a granular, powdery, or liquid (or gaseous) supplement or additive housing portion. The housing member 4 in this embodiment is a substantially cup-shaped member having a substantially cylindrical inner side wall portion 41 and an outer side wall portion 42, and a lower portion 42A having a large-diameter opening 44 formed at the bottom of the housing member. Have. The housing member can be filled with a material through the large-diameter opening 44 during assembly, and a cap member can be attached after filling. Thereafter, the valve member can be inserted and the port 41A of the receiving member can be closed until the valve member is actuated as described below.

  The accommodating member 4 can be formed of the above-described translucent or transparent plastic material, and may be opaque. The housing member 4 is configured to be attached to the cap member 3 at the lower portion 42A by screw tightening, snap fit, adhesive, welding, or other connection method. For example, the web top surface of the cap member has a web portion 31 that extends above the web portion and has a peripheral ridge 35 having a protrusion 35 </ b> A. And can be engaged with the projecting surface 42B having a corresponding shape by snap fitting, interference fitting or screw tightening. Thereby, sealing can also be performed.

  The cap member 3 preferably has an integrally formed O-ring shape that securely seals between the upper portion of the cap member and the inner side wall 41 and the valve member, and functions as an O-ring or a seal member. An upper portion 34 is included. A separate O-ring may be used. More specifically, the O-ring shaped upper part seals against the valve member (for example, the side wall part 20) and the product container (inner wall part 41) with which these members come into contact. The O-ring may be a separate body, but is preferably formed integrally with the cap member. The seal can prevent the material from leaking from the housing member at an early stage, and can prevent the supplement or additive material 47 from deteriorating due to moisture from the outside.

Valve Member As shown in FIG. 9, the cap assembly 1 includes a shuttle valve or valve member 2 having a hollow, substantially cylindrical wall portion 20 and an upper web portion 21 extending at one end beyond the end of the wall portion. Further included. A bottom flange 22 is formed at the tip of the wall, and the bottom flange 22 has an outer diameter larger than the diameter of the opening of the housing member 4. A tip portion 23 having a smaller diameter than the wall portion 20 extends upward from the surface of the web portion 21. The web portion 21 around the base portion of the tip portion 23 and / or the side wall 23C of the tip portion 23 can have one or more ports 21A and 23A, respectively. Ports 21A and / or 23A allow the beverage or liquid to pass from the bottle and if the nipple 5 is in the open or drinking position, the user can drink the beverage little by little (or drain the liquid from the bottle). be able to).

  The valve member has a base portion 25 and an inclined portion 26 located above the base portion. The base 25 closes the discharge opening 32A and prevents the port 41A of the housing member from communicating with the inside of the cap member and the contents of the bottle via the opening 32A. The upward movement of the valve member is limited by the interference between the lower flange 22 and the protrusion 31A protruding inward from the web portion of the cap member. At the time of shipment, the valve member is preferably in the upper position described above.

  The inclined portion 26 of the valve member has a column 26A and a port 26B. In use, for example, by pushing down the nipple until the nipple port 26B reaches a lower limit position that coincides with the openings / ports 41A and 32A, the valve member is pushed down from the initial or shipping position, and the liquid inside the cap member and in the bottle is removed. The supplement or additive in the storage chamber 40 can be mixed in communication with the storage chamber. By shaking the structure consisting of the bottle and cap, the liquid can be mixed into the additive.

Nipple As shown in FIG. 11, the nipple or nipple member 5 is sized to fit the valve member 2 and preferably has a substantially cylindrical body 50. The valve member 2 slides within the housing member 4 in which the main body 50 is preferably friction fitted. The nipple 5 has an upper protrusion from the side wall 41 and a main body portion 50 of the nipple from the lowest position where the bottom edge 50A contacts the horizontal flange 41B protruding inside the inner side wall portion 41 which is the lower limit position in the housing member. And slides to the uppermost position set using an interference fit with the outward projection from the body or the inward projection from the body and the valve member.

  When the nipple is closed as shown in FIG. 3 (and / or FIGS. 16 and 18), the inner rim of the upper surface 52 is pressed against the central port 51 formed on the upper surface 52 by a friction fit against the side wall 23C of the valve member. 52A is sealed so as not to communicate with the port or opening 21A and / or 23A of the valve member 20. Sealing and / or alternative means may be provided by the lower surface 52B of the upper surface 52 covering the port 21A. Note that the port 23A is preferably not provided. The upward movement of the nipple is substantially limited by friction and the stoppage of the upward movement by the user when the nipple moves high relative to the valve member until the port 21A and / or 23A seal is opened. In the open position shown in FIG. 17, since the port 21A (and / or 23A) is not covered by the nipple 5, the liquid can be passed from the bottle, and the user can drink or discharge the liquid from the bottle. Can do. The bottom of the nipple has an inward protrusion 50B for sealing with the wall member 20 of the valve member and causing friction with the valve member.

Universal mounting As described above, the cap member 3 seals the mouth of the bottle and secures the cap assembly 1 to the neck of the bottle so that it is relatively firmly fixed to the neck of the bottle having various sizes. Connect to (attach).

FIG. 12 is a partial cross-sectional view and a partial schematic view of the neck portion 62 of the bottle or container 60. The neck shown in FIG. 12 has an upper mouth 61 (bottle opening), a male thread 63, and a neck ring or flange 64. The size of the neck varies greatly depending on the type of bottle and the manufacturer. Usually, the neck portion has an inner diameter ID _{M at the} mouth portion, an outer diameter OD _{T at} the thread, an outer diameter D _{NR at} the neck ring, and a length or depth L _NR from the mouth or upper portion of the bottle or container to the neck ring. Have.

  13 to 15 are partial cross-sectional views of the cap assembly 1 attached to the bottle 60, and show only the cap member 3 and the neck region of the bottle. In FIG. 13, the bottle or container neck 62 has a first size (first dimension). In FIG. 14, the bottle or container neck 62 has a second size (second dimension). In FIG. 15, the bottle or container neck 62 has a third size (third dimension). 13 to 15, at least initially, the storage chamber 40 is filled with a supplement or additive for the user, and the bottle is in a filled state.

  The cap member 3 has two mechanisms to allow adaptation to various sizes of bottle or container necks, bottle mouth sealing structures and bottle neck grips or attachment structures.

Seal Structure The seal structure is formed on the lower surface of the region 37 of the web portion 34 and is sized to fit within the bottle neck and seal the bottle neck (preferably to fit various neck portions). Preferably, two seal members are provided. One of the seal members is a plug portion 37A extending downward over a longer distance than the outer seal portion 37B extending downward. Preferably, the plug portion 37A extends at a relatively small angle θ (eg, less than about 5 °, most preferably about 2 °) with respect to the vertical line. The other seal member is an outer seal portion that extends downward at a relatively small angle α (eg, about 10 °, most preferably about 9 °) with respect to the vertical line. Thus, the sealing member is formed in a conical shape, and the upper end of the sealing member does not have a frustum (the apex of the cone does not exist).

  Depending on the structure, angle and flexibility of the seal assembly, the plug and / or seal can be adapted to bottles having different diameters and different depths. Therefore, since the lower part of the sealing member functions to seal the bottle, the sealing member does not necessarily need to be accurately placed on the opening of the bottle.

  The length of the plug portion 37A is preferably 5 to 10 mm, and most preferably 7 mm. The length of the outer seal portion 37B is about one third or about 2 to 5 mm of the length of the seal portion 37A, but it may be longer or may be longer than the length of the plug portion. The conical plug portion 37A has sufficient width and elasticity to seal various sized necks against the bottle opening, and the distance between the bottle neck flange and the neck top is different. Even some cases can be dealt with.

The plug portion 37A preferably has an outward projection 37C at the lower end for sealing the inner surface of the bottle or the neck of the container. The plug portion 37A extends so as to have elasticity for maintaining a seal. A concave portion 37D that accommodates the mouth portion 61 of the bottle may be formed between the plug portion 37A and the seal portion 37B. More specifically, the concave portion 37D forms a space for accommodating the upper portion 21 of the bottle corresponding to the height of various neck portions. In some embodiments, the neck portion (especially ID _M (see FIG. 12)) is typically 25-28 mm or about 25-28 mm, more preferably 25-26 mm or about 25-26 mm, usually with various sizes depending on the plug portion 37A. Or 25 mm or about 25 mm (the ID _{M of} many bottles is 25 mm or about 25 mm (e.g. 29 (OD _T ) / 25 (ID _M ) or 30 (OD _T ) / 25 (ID _M ) The outer seal portion 37B can be omitted because the neck portion)) can be sealed, but can be sealed by the outer seal portion 37B when the dimension ID _M of the mouth of the bottle is large. The dimensions may be, for example, at least two or less of the diameter of the bottle neck according to the International Beverage Engineers Association (ISBT) standard. Both are selected to correspond to the three. Therefore, the seal member seals are pressed into the neck.

  The outer seal portion 37B can also seal a bottle neck having an inner diameter (for example, 30 mm and / or 32 mm) such that the outer seal portion is fitted into the mouth portion of the bottle. In the case where the inner diameter of the bottle is larger than the diameter of the circle centered on the axis of the cap member of the plug part, in particular, the diameter of the circle centered on the axis of the cap member at the attachment point of the seal part 37B to the web part of the cap member If larger, the outer seal portion 37B can function in the same manner as the plug member 37A.

Connection or Attachment Structure As described above, the neck grip or attachment structure includes the finger portion 30 and the return portions 30A and 30B. The cap member 3 and the finger portion 30 have such a size that the free end portion and other portions of the finger portion 30 bend outward when the cap member 3 is pressed against the bottle neck. In addition, the finger portion 30 has a free end portion, and is provided with a plurality of finger portions 30 and is relatively thin. Therefore, the finger portion 30 has elasticity, and the lower return portion 30A and the intermediate return portion 30B. Engage below the neck ring and / or thread extending from the neck of the bottle.

The number of finger portions is not limited, but at least 6 to 16, preferably 10 to 14, and most preferably 12 finger portions are provided so that sufficient flexibility is obtained. As shown in FIGS. 12 to 15, when the length in the vertical direction of the finger portion measured as the length from the concave portion 37D or the vicinity of the concave portion 37D to the upper surface of the lower return portion 30A is L _MAX , L _MAX is ( representing the maximum height of the distance a is) the neck ring is the height L _NR from bottle top 61 which forms a mouth to the lower surface 64A of the neck ring 64 or the neck flange. The diameter of the neck ring measured from the outermost part of the neck ring 64 is _DNR . According to ISBT standard 1810, the distance _{L NR} is 21 mm, the distance to the bottom thread is 14.1 mm, the diameter _{D NR} of the neck ring is 33 mm, the diameter OD _T of the thread is 27.4mm is there. According to ISBT standard 1881, the distance _{L NR} is 17 mm, the distance to the bottom thread is 11.2 mm, the diameter _{D NR} of the neck ring is 33 mm, the diameter OD _T of the thread is 27.4mm is there. The inner diameter ID _T of the mouth in ISBT standard 1810 and ISBT standard 1881 is 21.7 mm.

According to the standard 26P-1, the distance _{L NR} is 17 mm, the distance to the bottom thread is 10.6 mm, the diameter _{D NR} of the neck ring is 31.9 mm, the diameter OD _T of the thread 27 .2 mm. The inner diameter ID _{T of the} mouth is 21.8 mm. According to the standard 26P-2, the distance _{L NR} is 17 mm, the distance to the bottom thread is 10.6 mm, the diameter _{D NR} of the neck ring is 33 mm, the diameter OD _T of the thread is 26.6mm It is. The inner diameter ID _{T of the} mouth is 21.8 mm. There are several differences between these standards. Accordingly, a suitable diameter for the finger portion is from about 25 mm to about 35 mm, more preferably from about 27 to 31 mm, and most preferably about 28 mm. A suitable diameter of the inner seal member at the convex portion 21C is 24-26 mm, most preferably about 25 mm, and a suitable diameter of the outer seal portion at the lowest point is 24.5-26.5 mm, most preferably about 25 mm. 25.5 mm. In addition, the dimension described in this specification is only an example, and the cap assembly 1 may have other dimensions that fit the neck portion of the bottle and seal the neck portion.

  For example, the range of inner and outer diameters of the bottle that can be sealed by the cap member may vary by about 1 or 1.5 mm, 2 mm, 5 or 10 mm or more. The depth range of the neck flange may vary by about 2 or 3 mm, 5 or 10 mm or less.

Lower back portion 30A and the intermediate return portion 30B, regardless of the length L _NR, to be able to grip the lower surface of the neck flange, are formed so as to extend inwardly in the same or substantially the same length ing. For example, in FIGS. 13 to 15, the lengths to the flanges are L _N1 , L _N2 , and L _N3 , respectively. Therefore, in FIG. 13, the neck flange is deep and is gripped by the lower return portion 30A. In FIG. 14, the neck flange is shallow and is gripped by the upper surface of the intermediate return portion 30B. In FIG. 15, the neck flange has an intermediate depth and is gripped by the lower surface of the intermediate return portion 30B.

13 to 15, the dimensions of the neck portion are different. For example, in FIG. 13, the diameter D _{F of the} neck flange, the outer diameter D _O of the upper portion of the bottle and the inner diameter D _I of the bottle are large, and the plug portion 37A and In FIG. 14, the diameter D _{F of the} neck flange, the outer diameter D _O of the upper part of the bottle and the inner diameter D _I of the bottle are small in FIG. 14, and will engage with the plug part 37A. In FIG. 15, the diameter D _{F of the} neck flange, the outer diameter D _O of the upper part of the bottle, and the inner diameter D _I of the bottle are intermediate between them, and engage with the plug part 37A, and the inward deflection of the plug part is shown in FIG. Smaller than.

  As shown in FIG. 13, the return portion may engage the thread. That is, the intermediate return portion 30B is engaged with the lower surface 63A of the screw thread 63. As seen in various ISBT standards, the lowest thread has a relatively flat lower surface that can be gripped by an intermediate return. Thus, depending on the neck, the return may engage the thread, the neck flange and / or the thread and the neck flange. Engagement and grip, unlike screw tightening, results in a more secure engagement to the bottle neck even with a slight rotation of the cap assembly 1.

  In the embodiment shown in FIG. 19, the length of the seal part 37B shown in FIGS. 13 to 15 is increased to form the seal part 37F. That is, the seal portion 37F is formed in the same manner as the plug portion 37A. As shown in FIG. 19, the bottle has a neck portion 62 having a relatively large inner diameter and outer diameter. In this case, the upper portion 61 of the bottle is located outside the seal portion 37F, and the seal portion 37F acts in the same manner as the plug portion 37A shown in FIGS. 13 to 15 to seal the mouth portion of the bottle from the inside. A space for accommodating a larger bottle is formed by the recess 37E. Further, the web portion 34 in the region 37 is curved upward in the direction toward the outside (the direction away from the central axis of the cap assembly 1), and the neck from the bottle mouth or upper portion 61 to the neck flange 64 is large. A space for accommodating the part can be provided. With the above structure, for example, a bottle having a larger size range can be accommodated.

  As is apparent from the above-mentioned drawings, the return portions 30A and / or 30B of the finger portion 30 are pressed against the flange 64 and / or thread 63 of the bottle, and the user pushes down the cap assembly 1 against the bottle neck. At this time, the cam or the inclined lower surface of the return portion converts the pressing force into a bending force that spreads the finger portion outward, so that the cap assembly 1 can be easily attached. When downward pressure is applied to the cap assembly 1, the plug portion 37A contacts the inside of the bottle and / or the seal portion 37B (or 37F) contacts the top of the neck, and the plug portion 37A and / or the seal portion 37B (or 37F) bends but is biased against the interior of the bottle and / or the top of the neck to seal the opening or mouth of the bottle. The return portion passes over the thread and / or flange, and the cap assembly 1 is brought into place by engagement of the horizontal upper surface of the lower return portion and / or the intermediate return portion with the lower surface of the flange and / or thread. Lock.

Shipping, Mixing and Drinking Positions FIGS. 16-18 show the cap assemblies 1 set to a shipping position, a drinking position or a mixing position (non-drinking position), respectively. FIG. 16 shows the cap assembly 1 set in an unmixed (shipped) position with the nipple 5 and valve member 2 lowered. FIG. 18 shows the cap assembly 1 set in the mixing position with the nipple 5 and valve member 2 fully lowered. The cap assembly 1 is normally set to the mixing position when the user sets the opening of the valve member to communicate with the opening communicating with the interior of the storage chamber. Even when the nipple is closed, the position shown in FIG. 18 is set. FIG. 17 shows the cap assembly 1 set in the drinking position, and lifts the nipple 5 away from the top of the valve member 2 (the valve member 2 may be lowered or set in another position). The nipple opening communicates with the contents of the bottle, and the user can drink the contents of the bottle.

  In the shipping position, the contents of the cap assembly 1 are held in the storage chamber 40 and no fluid can enter the storage chamber. In the illustrated embodiment, the nipple 5 is in a relatively low (not lifted) position so as to cover the upper openings 21A, 23A of the valve member. The valve member is in a position sufficiently higher than the position where the opening or port 26B of the valve member communicates with the opening 41A of the housing member 4 and the opening or port 32A of the cap member 3. In the shipping (storage or non-use) position, the valve member is preferably at the upper limit position or a position close to the upper limit position.

  In another (less preferred) embodiment, fluid communication between one or more openings in the valve member and one or more openings in the cap member can be blocked by another mechanism.

  In some embodiments, the cap assembly is shipped in the locked position to prevent the valve member 2 from being accidentally lowered relative to the cap member from the stowed or shipped position to the mixing position. The cap assembly can be released from the locked position by rotating one or more of the nipple 5 and the valve member 2. The locking system can be similar to a locking system for liquid soap containers or hand lotion containers, for example, in which the valve member cannot be pushed down without rotating the valve member by a quarter turn.

  Although the position shown in FIG. 16 can be changed from the position shown in FIG. 16, it is preferable that the mixing position shown in FIG. As shown in FIG. 18, when the cap assembly 1 is in the mixed (non-drinking) position, supplements and / or additive fluids may move between the housing member 4 and the hollow interior of the valve member 2. it can. The hollow interior of the valve member 2 serves as a flow path 28 that communicates with the bottle and the nipple and communicates the storage chamber 40 with the contents of the bottle. In the above position, the nipple 5 and / or the tip 23 of the valve member are pushed down so that the port or opening 26B of the valve member is aligned with the port or opening 32A of the cap member and the opening 41A of the receiving member to communicate with each other. Until the valve member is moved downward relative to the cap assembly. Thereby, the contents of the bottle pass through the flow path 28 of the valve member and enter the receiving container, and the contents 47 of the receiving container enter the bottle through the flow path 28. Thereby, mixing can be performed. That is, by placing the nipple 5 in the lowered / closed position, fluid is prevented from passing through the nipple opening 51 and the cap assembly 1 is engaged with a bottle filled with fluid that mixes supplements or additives. be able to. Since the contents of the bottle cannot be drunk at the relative position between the nipple and the valve member shown in FIG. 18, it is also a non-drinking position.

  In another embodiment, the mixing position can be achieved by performing fluid communication between the containment chamber 40 and the flow path 28 by performing one or more of the engagement and / or release operations described above.

  As shown in FIG. 17, preferably after completion of mixing or when drinking or discharging the contents of the bottle, the nipple 5 is lifted against the valve member and the cap assembly so that the user can remove the contents from the bottle connected to the cap member. Be able to drink things.

  If the storage chamber 40 contains a supplement or additive, it is preferable to mix the fluid consumed or used at this point with the supplement or additive. Engagement between the interference line and the flange of the valve member or other means can prevent the nipple 5 from detaching from the cap assembly. There is sufficient frictional engagement between the cap assembly and the nipple to hold the nipple upward in the drinking position (or discharge position) in use and downward in the mixing or storage position.

  As shown in FIG. 17, by pulling up the nipple above the valve member, the fluid can be put into the flow path 28 via the port 21A and / or 23A and can be swallowed via the opening 51. Become. The valve member may move to a position that prevents fluid communication with the storage chamber 40 and / or move from a position that prevents fluid communication with the storage chamber 40. However, it is not necessary to hold the valve member in the mixing position after preferably mixing the liquid and additive in the bottle until the additive is completely dissolved in the liquid in the bottle or thoroughly mixed. The valve member can operate properly without locking or releasing the lock from the mixing position.

  As is clear from the above description, by pushing the nipple back against the valve member, the communication with the ports 21A and / or 23A is cut off and the flow through the opening 51 does not occur. It can be a drinking or non-releasing position.

Assembling the Cap Assembly When assembling the cap assembly, the valve member 2 is pushed inward from the bottom so as to extend from the top of the cap member 3. Before or after this step, the containing member 4 can be turned over and filled with supplements, flavors or other additives. The valve member and cap member can be assembled together (if not already assembled). Next, the valve member and the cap member are connected to the accommodating member by inserting the valve member inside the inner wall of the accommodating member, and the cap member is engaged with the accommodating member by, for example, snap fitting. As described above, in the shipping condition, the valve member 2 has a window portion that is shifted in the vertical direction from the port on the inner wall at the top of the cap member. The port of the cap member is aligned with the storage chamber of the storage member by the opening or the passage. Next, the nipple 5 is inserted into the housing member 4 so as to cover the valve member.

  Although one cap assembly 1 is preferably used, a plurality of cap assemblies 1 can also be used. It is also possible to ship in a state in which the storage chamber is filled with a supplement or the like, or the user can fill the supplement or the like.

Structure consisting of three or fewer members In another embodiment, the cap assembly described above can be composed of three members. The structure can be formed of polypropylene or other materials disclosed herein or other equivalent plastics or materials. The operation is the same as that of the above embodiment. In this embodiment, the outer part formed with the thread of the cap member, the product container, and the hinge type valve cover on the upper part of the receiving member are formed by one member. The cap member has a seal portion and an attachment structure. The remaining members are valve members, and the valve members function as drinking holes, and nipples are unnecessary.

  Or while forming a cap member and an accommodating member with one member, a valve member and a nipple are formed with one member, and it can also be set as the cap assembly which consists of two members. The cap member has a web part (finger, return part, seal part and plug part) or an attachment structure and a seal structure which is provided below the web part to be a universal attachment, and has only a sports bottle nipple. In this case, the storage chamber and the valve member are not necessary. The top of the cap member may form an inner wall (such as the inner wall 41 of the receiving member) through which the nipple (such as nipple 5) moves. The cap member has at least a part of the cap member such as the upper part including the port of the valve member, and is closed by moving the nipple downward and opened by moving the nipple upward. be able to.

  Moreover, it can also be set as the universal bottle cap which consists only of a cap member and consists of one member, In this case, a web part is solid (a liquid is not allowed to pass through), or when opened, it is liquid. Is an openable and closable flap that does not pass liquid when closed. Of course, any of the above-described four members and / or additional members can be divided into a cap assembly made up of more members.

Other Modifications Although specific embodiments of the present invention have been described, various modifications and changes can be made without departing from the scope and spirit of the present invention. For example, if a thread is used instead of a finger with a return (gripping the neck ring) or a finger with a thread, the cap system will be sized to fit a particular bottle. In such an embodiment, the universal mounting ability of the finger having the return portion will be impaired. If the number of fingers is 10, 12, or 14, it is preferable because the width of the fingers can be reduced as compared with the case of having 6 fingers, for example. The size and material of the fingers and return parts, the number of fingers and return parts, and the spacing between the fingers affect the elasticity of the fingers. The elasticity of the fingers is such that the downward force required to seal the bottle with the sealing member by pressing the fingers against the neck of the bottle is less than the deformation point and breakage point of the bottle. To provide at least 10 or at least 12 or at least 14 fingers to give the fingers good flexibility and elasticity, reduce the downward force on the bottle, and drink the contents of the bottle It is possible to prevent the cap member from being lifted from the bottle when the nipple is lifted. The force required to attach the cap member to the bottle must be less than that which would cause the user to break the bottle.

  Although a finger attachment mechanism is preferred, the attachment can also include a member having threads that are screwed into the bottle. The threaded member can have a thread configured to engage one or more bottle threads.

  A groove or a recess for accommodating at least a neck ring and / or a part of a screw thread is provided on the inner wall of the finger directly above the lower return portion 30A and / or just above the intermediate return portion 30B, and attached to the neck of the bottle. It can be made more reliable.

  While multiple ports and openings through which fluid flows are disclosed, variations using one port or opening instead of multiple ports or openings and / or variations using more ports or openings are also possible. Is possible.

  In an embodiment where the cap assembly is inserted into the bottle like a stopper, the cap assembly is caused by frictional resistance between the surface of the bottle and a member of the cap assembly (eg, plug portion 37A and / or seal portion 37B (or 37F)). Can be held. In another embodiment, the cap assembly has one of the attachment mechanisms with the fingers described above and does not have a valve system and / or supplement containment, mixing and / or release system, and bottles of various sizes. It may be a cap that can be attached to. For example, the bottle size ranges are 5-25 mm (neck height range) and 16-32 mm (bottle neck opening diameter range). The normal diameter range is 21-32 mm.

  Instead of using powdered supplements or additives, liquid or gaseous supplements or additives can also be used. For example, the container can be filled with a substance whose contents are carbonated beverages when mixed with compressed gas and / or bottle contents.

  In another embodiment or variant, the cap member is sized to have a finger or threaded cylindrical outer portion that attaches to a threaded neck of a particular size. Can do. In another embodiment, the valve system, nipple and product container may be included in a simple nipple / valve or product container or replaced with a simple nipple / valve or product container, the valve system being threaded Can be used with a simple attachment mechanism or other bottle attachment mechanism.

  Depending on the structure, angle and flexibility of the seal assembly, the plug and / or seal can be adapted to bottles having different diameters and different depths. Therefore, since the lower part of the sealing member functions to seal the bottle, the sealing member does not necessarily need to be accurately placed on the opening of the bottle.

  The valve member extends radially outward from the base or other portion, and abuts against, for example, an upper ring portion formed on the cap member 3 to restrict downward movement of the valve member 2 relative to the cap member and the cap assembly. One or more limiting members may be included.

  Because the bottle may have different dimensions between the neck flange and the top surface of the neck, at least a portion of the cap finger portion 30 has two return portions (lower return portion 30A and intermediate return portion 30B). Is formed. In the embodiment described above, each finger portion 30 is formed to have a lower return portion and an intermediate return portion. In another embodiment, a portion of the finger portion 30 can be formed with a lower return portion and / or an intermediate return portion, or can be formed without a return portion. In another embodiment, a part of the finger part 30 may have only the lower return part, and the other finger part may have only the intermediate return part.

  The intermediate return portion 30B may be formed in a curved shape so that the neck ring slides more easily when the cap member is disposed on the bottle. The intermediate return portion 30B may have the same shape as the lower return portion so that it can be gripped better.

  In a preferred embodiment, the cap member is made of plastic, so the cap member may be transparent, opaque or translucent and may have any color. At least in the case of a containment member, the user can see the mixing state, and when the user drinks the contents, the valve member is in the mixing position, when the user drinks the contents or other It is advantageous to be transparent or translucent so that the liquid in the storage chamber can be seen during use.

  Although the present invention has been described using specific terms, apparatus, and / or methods, the above description is intended only to illustrate preferred embodiments. Those skilled in the art can make various modifications to the preferred embodiments without departing from the scope of the present invention as set forth in the claims. Simple variations include changing the outer shape of the containment vessel to a cartoon character, animal or other shape, making the vessel transparent, opaque, translucent, or a combination thereof, and / or materials other than plastic and rubber Can be used. Also, aspects of the preferred embodiments can be interchanged in whole or in part.
