[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a lid for a beverage container detachably attached to the mouth of a beverage container such as a plastic bottle, and more particularly to a lid for a beverage container suitable for drinking a beverage with a straw.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, for example, plastic bottles, glass bottles, and the like are well known as beverage containers that are filled with a beverage such as refreshing drinking water and are sold in a form in which a mouth is sealed with a lid. As one method of drinking the beverage in the beverage container, there is a method of removing the lid from the mouth, inserting a straw through the mouth, and sucking up the beverage through the straw to drink. This method is convenient when you want to drink a beverage little by little or when you want to drink a beverage without holding a beverage container. Unlike drinking beverages with the lips against the mouth or with the mouth held in the mouth, there is the advantage that the beverage container does not need to be tilted or raised.

[0003]

[Problems to be solved by the invention]

 However, when drinking a beverage with a straw while holding the beverage container, if the beverage container is excessively tilted or dropped, not only does the beverage leak out of the beverage container through the straw, but also the straw and the mouth. There was a problem that a large amount leaked out from the room. Such problems were more likely to occur when infants and children drink beverages in the manner described above. In addition, when the beverage container is placed on a table or the like and the beverage container is drastically tilted or falls down due to unintentional hand contact when drinking the beverage with a straw, the same as described above. The problem was going on.

[0004] Therefore, an object of the present invention is to provide a lid for a beverage container which can make the beverage hardly leak even if the beverage container into which the straw is inserted is inclined.

[0005]

A beverage container lid according to a first aspect of the present invention includes a mounting portion detachably mounted on a mouth portion of a beverage container, and a mouth portion at the time of mounting. A main body having a mouth closing portion for closing the opening, and a straw insertion portion formed of a hole provided in the mouth closing portion of the main body.

According to the beverage container lid of the first invention, when the beverage inside the beverage container is to be drunk using a straw, the mounting portion of the beverage container lid is attached to the mouth of the beverage container. Next, pass the straw through the straw insertion part of the mouth-blocking part, hold the beverage container by hand, hold the end of the straw and suck up the beverage. At this time, even if the beverage container is tilted excessively, only a small amount of the beverage leaks. This is because most of the mouth is closed by the mouth blocking part, and the place where the beverage can leak out is limited to the slight gap between the outer peripheral surface of the straw and the wall surface of the straw insertion part. Because it is. The same applies to the case where a beverage container is accidentally dropped or the beverage container is put on a table or the like, and the beverage container is mistakenly knocked down while the beverage is stopped once with the straw inserted in the straw insertion part. . In this case, the beverage also leaks from the straw, but in much less volume than without the beverage container lid.

A beverage container lid according to a second aspect of the present invention, in addition to the configuration of the first aspect, is characterized in that the mouth closing portion makes the straw inserted into the straw insertion portion unable to move up and down. Further, holding means for holding is provided.

According to the beverage container lid of the second invention, when the user releases his / her hand from the straw passed through the straw insertion part, the holding means holds the straw immovably up and down. The straw is maintained at the height when the hand is released even if the lower end is away from the inner bottom of the beverage container.

A beverage container lid according to a third aspect of the present invention, in addition to the configuration of the second aspect, is characterized in that the holding means is in close contact with the outer peripheral surface of the straw passed through the straw insertion portion. It has a smooth contact portion.

According to the beverage container lid of the third invention, when the straw is passed through the straw insertion portion, the adhesion portion comes into close contact with the outer peripheral surface of the straw. The straw is held immovable up and down due to the friction between the outer peripheral surface of the straw and the contact portion due to the close contact.

According to a fourth aspect of the present invention, in addition to the configuration of the third aspect of the present invention, the beverage container lid is configured such that the close contact portion is formed of an elastic annular member mounted in the straw insertion portion. .

According to the beverage container lid of the fourth invention, when the straw is passed through the straw insertion portion, the elastic annular member in the straw insertion portion elastically adheres over the entire circumference of the straw outer peripheral surface. The contact area between the contact portion and the outer peripheral surface of the straw is increased, and the holding force of the holding means is increased.

According to a fifth aspect of the present invention, there is provided a beverage container lid according to any one of the first to fourth aspects, further comprising a stopper that is removably fitted into the straw insertion portion. Have.

[0014] According to the beverage container lid of the fifth invention, when the beverage is left undrinked, the straw is removed from the straw insertion portion, and the stopper is fitted into the straw insertion portion. Then, the straw insertion portion is closed and there is no place where the beverage can leak. When the stopper is removed, the straw insertion part is opened and the straw can be passed through it.

According to a sixth aspect of the present invention, in addition to the configuration of the fifth aspect, the beverage container lid further includes a connecting portion that connects the stopper to the main body.

According to the beverage container lid of the sixth invention, the stopper is fitted into or pulled out of the straw insertion portion while being connected to the main body by the connecting portion.

According to a seventh aspect of the present invention, there is provided a beverage container lid according to any one of the first to sixth aspects, wherein the mounting portion is formed of an elastic material in a tapered shape. I have.

According to the beverage container lid of the seventh invention, when attaching the beverage container lid, the tapered mounting portion is pushed into the mouth. During the pushing process, the mounting part comes into close contact with the inner peripheral surface of the mouth. The contact portion of the mounting portion with the mouth differs depending on the diameter of the mouth. If it is pushed in a little too hard, the mounting part will be elastically deformed and adhere to the shape of the mouth, and it will not come out of the mouth easily. In this state, the gap between the mounting portion and the mouth is almost eliminated.

[0019]

[Embodiment of the invention]

 First Embodiment Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. First, a beverage container 1 in which the beverage container lid of the present embodiment is used will be described. The beverage container 1 includes a container body 2 in which soft drinks and the like are put, and a lid (not shown) detachably attached to an opening 3 of the container body 2. The mouth 3 has a cylindrical shape, and an external thread 4 is formed on an outer peripheral surface thereof for mounting a lid. As the beverage container 1, for example, a so-called PET bottle formed of at least as-is recyclable PET resin (polyethylene terephthalate) is well known. In the case of plastic bottles, the size, shape, etc. of the mouth 3 are common regardless of the capacity. The beverage container 1 may be something other than a plastic bottle, for example, a glass bottle.

Next, the beverage container lid 5 will be described. The beverage container lid 5 is used in place of the lid originally attached to the beverage container 1 when drinking beverage mainly using the straw 6. The main body 7 occupying most of the beverage container lid 5 includes a mounting portion 8 detachably mounted on the mouth portion 3 and a mouth closing portion 9 for closing the mouth portion 3 when the mounting portion 8 is mounted. ing. The mounting portion 8 has a cylindrical shape, and a female screw 10 screwed to the male screw 4 is formed on the inner peripheral surface thereof. The mouth closing portion 9 has a substantially disk shape, and is provided integrally with the upper end of the mounting portion 8. The mouth closing portion 9 is provided with a straw insertion portion 11 having a round hole slightly larger in diameter than the general straw 6. Although the position of the straw insertion portion 11 in the mouth blocking portion 9 is not particularly limited, the straw insertion portion 11 is located at the center of the mouth blocking portion 9 here.

The beverage container lid 5 further includes a stopper 12 and a connecting portion 13. The stopper 12 includes a cylindrical portion 14 having substantially the same diameter as the straw insertion portion 11, and a stopper 15 formed at one end of the cylindrical portion 14 and having a larger diameter than the cylindrical portion 14. The connecting portion 13 is for connecting the stopper 12 to the main body portion 7 and has flexibility. The connecting portion 13 has an elongated shape, one end of which is connected to the outer peripheral portion of the mouth closing portion 9, and the other end of which is connected to the stopper 15. The connecting portion 13 may be connected to a portion other than the above, for example, to the mounting portion 8. The connecting portion 13 has a length necessary for the cylindrical portion 14 to reach the straw insertion portion 11 when closing the straw insertion portion 11 with the stopper 12. The beverage container lid 5 is constituted by the main body 7, the straw insertion portion 11, the stopper 12, and the connecting portion 13 described above. The material of the beverage container lid 5 is not particularly limited, but synthetic resin is suitable in terms of ease of molding and the like. Here, the entire beverage container lid 5 is integrally formed of a single synthetic resin material. When the connecting portion 13 is formed as a separate component using a material different from that of the main body portion 7 and the plug 12, a chain, a string, or the like may be used as the connecting portion.

Next, the operation and effects of the present embodiment configured as described above will be described.

When drinking the beverage inside the beverage container using the straw 6, the original lid is removed from the mouth 3. The beverage container lid 5 is attached to the beverage container 1 by screwing the female screw 10 on the inner periphery of the mounting portion to the male screw 4 on the outer periphery of the mouth. Next, the straw 6 is passed through the straw insertion portion 11 and inserted until the lower end of the straw 6 reaches or near the inner bottom of the beverage container 1. Then, the user holds the beverage container 1 by hand and holds the upper end of the straw 6 to suck up and drink the beverage. At this time, even if the beverage container 1 is excessively tilted, only a small amount of beverage leaks. This is because, in addition to the fact that most of the mouth 3 is closed by the mouth closing portion 9, the location where the beverage can leak out is slightly between the outer peripheral surface of the straw 6 and the wall surface of the straw insertion portion 11. This is because it is limited to the gap. Also, when the beverage container 1 is placed on a table or the like and the beverage container 1 is greatly inclined due to unintentional hand touch when drinking the beverage with the straw 6 in the same manner as described above. The beverage hardly leaks.

Further, even if the beverage container 1 is accidentally dropped while drinking a beverage, the amount of the leaked beverage is small. In this case, the beverage leaks out of the straw 6 in addition to the gap between the outer peripheral surface of the straw 6 and the wall surface of the straw insertion portion 11, but it is far less than when the beverage container lid 5 is not used. The same effect can be obtained when the user stops drinking the beverage while the straw 6 is still inserted, places the beverage container 1 on a table or the like, and the beverage container 1 falls down. As described above, according to the present embodiment, unlike the related art in which the straw 6 is inserted directly into the mouth portion 3 to drink the beverage, the beverage container 1 into which the straw 6 is inserted may be inclined or fall. Also, the amount of beverage leaking from the beverage container 1 can be reduced. This makes it easier to clean up the leaked beverage. These effects are particularly effective for infants and children who easily fall or drop the beverage container 1.

When the beverage is left unreacted, the straw 6 is withdrawn from the straw insertion portion 11, and the position of the cylindrical portion 14 of the stopper 12 is adjusted to the straw insertion portion 11 while bending the connecting portion 13. The stopper 12 is pushed down, and the column 14 is fitted into the straw insertion portion 11. When the stopper 15 hits the mouth closing portion 9, further insertion of the cylindrical portion 14 becomes impossible. In this way, the straw insertion part 11 is closed by the stopper 12, and there is no place where the beverage can leak. Even if the beverage container 1 tilts or falls, the beverage does not leak. To drink the remaining beverage again, hold the stopper 15 and pull it up. Then, the cylindrical portion 14 comes out of the straw insertion portion 11, and the straw insertion portion 11 is opened. The straw 6 can be passed through the straw insertion portion 11.

The present embodiment has the following features in addition to the items described above.

(A) Since the stopper 12 is provided in the vicinity of the straw insertion part 11, the straw insertion part 11 can be immediately closed when the beverage is desired to be left. Further, the stopper 12 is inserted into or removed from the straw insertion portion 11 while being connected to the main body 7 by the connecting portion 13. In other words, since it is always the same as the main body 7, there is no fear of being lost.

(B) Since the mounting portion 8 of the beverage container lid 5 is screwed to the mouth portion 3, after use, the beverage container lid 5 is turned and removed from the mouth portion 3. , Can be mounted in another beverage container. For this reason, the beverage container lid 5 can be used repeatedly. In this case, if the beverage container lid 5 is washed with water, it can be always kept in a clean state. In particular, when the entire lid for a beverage container is formed of a synthetic resin, the lid is not rusted by washing with water, which is preferable for hygiene.

(C) Since the beverage container lid 5 has a simple structure, it is easy to manufacture. In particular, if the lid 5 for a beverage container is integrally formed by molding using a synthetic resin material, the effect of reducing the production cost by mass production can be expected.

(D) The beverage container lid 5 is attached to the mouth portion 3 by using the male screw 4 originally formed on the outer peripheral surface of the mouth portion 3. There is no need to adopt a structure.

(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. The second embodiment is significantly different from the first embodiment in that the mouth closing portion 9 is provided with holding means for holding the straw 6 inserted into the straw insertion portion 11 so as not to move up and down. doing. More specifically, the holding means includes a contact portion that is in close contact with the outer peripheral surface of the straw 6 passed through the straw insertion portion 11. Here, a ring-shaped elastic annular member 16 made of a material having elasticity such as rubber or elastomer is used as the contact portion. The elastic annular member 16 is fixed to a wall surface or the like of the straw insertion portion 11 by means such as bonding. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Further, in FIG. 3, the plug 12 and the connecting portion 13 are omitted, but they may be provided in the same manner as in the first embodiment.

Therefore, according to the second embodiment, the same operations and effects as those of the first embodiment can be obtained. In addition, when the user releases his hand from the straw 6 passed through the straw insertion portion 11, the straw 6 is held immovable up and down due to friction between the elastic annular member 16 and the straw. Therefore, even if the lower end of the straw 6 is separated upward from the inner bottom of the beverage container 1, the straw 6 is maintained at the height when the hand is released. With such a simple configuration, the height of the straw 6 can be adjusted, and the beverage can be drunk at a desired height. Further, it is possible to prevent the short straw 6 from falling out of the straw insertion portion 11 and entering the beverage container 1. Further, in the second embodiment using the elastic annular member 16 as the contact portion, the elastic annular member 16 elastically adheres over the entire outer peripheral surface of the straw. Compared with the case where the close contact portion comes in contact with the outer peripheral surface of the straw, the contact area is increased, and the holding force can be effectively increased. The gap between the inner peripheral surface of the elastic annular member 16 and the outer peripheral surface of the straw becomes extremely small, and the amount of beverage leaking from this can be extremely reduced. Also, due to the holding, the straw 6 is hard to move upward. For this reason, the straw 6 does not easily come out of the straw insertion portion 11 with such a force that an infant or a child drinking a beverage using the straw 6 grasps the straw 6 and pulls it up.

The present invention can be embodied in another embodiment described below.

(1) As shown in FIG. 4, a tubular grip 17 may be provided on the upper surface of the mouth closing portion 9 so as to protrude while surrounding the straw insertion portion 11. When drinking a drink using the straw 6, the straw 6 is passed through the straw insertion portion 11 through the mouth portion 17. At this time, the mouth 17 surrounds a part of the straw 6 so that external force does not reach the straw 6. The mouth 17 also has a function of maintaining the straw 6 at a fixed angle (for example, at a right angle to the mouth closing part 9). Furthermore, the mouthpiece 17 performs its main function when the straw 6 is not prepared. That is, the user can drink the beverage by directly holding the mouth 17. Since the diameter is smaller than the mouth 3 (substantially the same diameter as the straw 6), there is an advantage that the mouth 3 is easier to hold than when drinking a drink by directly holding the mouth 3.

Further, as shown in FIG. 4, an auxiliary lid 18 which can be detachably attached to the outside of the grip 17 may be provided. By doing so, the same effect as the effect of the stopper in the first embodiment can be obtained. That is, if the auxiliary lid 18 is put on the grip 17, the grip 17, and thus the straw insertion part 11, is closed by the auxiliary lid 18, and there is no place where the beverage can leak. Even if the beverage container 1 tilts or falls, the beverage does not leak. Further, the auxiliary lid 18 may be connected to the main body 7 by the connecting portion 13. In this manner, similarly to the effect of the connecting portion 13 in the first embodiment, the auxiliary lid 18 is less likely to be lost, and the auxiliary lid 18 can be immediately put on the grip 17 when necessary.

(2) The beverage container lid 5 of the present invention is also applicable when a glass bottle is used as the beverage container. However, since the glass bottle usually has a mouth different from that of the PET bottle (no male screw), it is necessary to appropriately change the structure for attaching the mounting portion 8 to the mouth. For example, as shown in FIG. 5, the mounting portion 8 may be formed of an elastic material such as rubber to have a tapered shape such that the diameter decreases toward the lower side. When attaching the beverage container lid 5 to the mouth, the attachment portion 8 is pushed into the mouth. During the pushing process, the mounting portion 8 comes into close contact with the inner peripheral surface of the mouth. The contact portion of the mounting portion 8 with the mouth differs depending on the diameter of the mouth. This is because the larger the diameter, the more the mounting portion 8 enters the mouth. If it is pushed in a little more strongly, the mounting portion 8 adheres tightly while elastically deforming according to the shape of the mouth, so that it is difficult for the mounting portion 8 to come off from the mouth. In addition, in this state, there is almost no gap between the mounting portion 8 and the mouth, and there is no danger that the beverage will leak from the gap. Thus, the mounting portion 8 is mounted by being pushed into the inside of the mouth. For this reason, even if not only a glass bottle but a PET bottle is used as a beverage container, it can be used as the lid 5 for the beverage container. In addition, in the case of this type of mounting portion 8, there is an advantage that a plurality of types of beverage containers having different mouth diameters can be handled.

(3) A plurality of flexible pieces may be provided in the straw insertion portion 11 in order to enhance the adhesion of the straw insertion portion 11 to the straw 6. For example, as shown in FIG. 6, a hole having a continuous convex and concave portion such as a saw tooth is formed in a part of the sheet 19 in which a thin and flexible sheet 19 is stretched over the mouth closing portion 9. These convex and concave portions are used as a plurality of flexible pieces. In addition, instead of holes having projections and depressions, radial (for example, cross) cuts may be made in the sheet 19. In this case, a portion sandwiched between adjacent cuts corresponds to a flexible piece. In this way, when the straw 6 is passed through the straw insertion portion 11, the flexible piece bends downward and comes into close contact with the outer peripheral surface of the straw 6. Therefore, in these cases, the straw 6 can be held similarly to the second embodiment. In addition, there is an effect that straws having different thicknesses can be handled.

(4) In the first embodiment, the cylindrical portion 14 of the plug 12 is fitted into the straw insertion portion 11 in order to close the straw insertion portion 11. Can also be obtained by indirectly blocking For example, as shown in FIG. 6, an auxiliary cover 18 having substantially the same diameter as the mouth closing portion 9 is provided, and the straw insertion portion 11 is closed by overlapping the auxiliary cover 18 on the mouth closing portion 9. In this case, if the auxiliary cover 18 is connected to the main body 7 by the hinge 22, particularly to the outer peripheral portion of the mouth closing portion 9, the auxiliary cover 18 is bent at the hinge portion, and the auxiliary cover 18 is closed. The straw insertion portion 11 can be opened by closing the straw insertion portion 11 by overlapping the straw insertion portion 9 or inclining the auxiliary lid 18. Further, when the auxiliary lid 18 is overlaid on the mouth blocking part, a locking recess 20 is provided in the main body (for example, the mounting part) 7 so as to prevent the auxiliary lid 18 from inadvertently floating. The hook 21 may be provided with a claw 21 which is locked to the locking recess 20 when it is overlaid on the mouth closing portion 9. Although not shown, a claw portion may be provided on the main body 7 and a locking recess may be provided on the auxiliary lid 18.

(5) The mouth closing portion 9 may be provided with a small hole for venting air.

(6) As shown in FIG. 7, according to the present invention, a mounting portion 8 that is removably mounted to the mouth portion 3 by press-fitting, and an outer diameter of the mouth portion 3 that is provided at an upper end of the mounting portion 8 The present invention may be embodied in a beverage container lid 5 which essentially includes a mouth closing portion 9 having the same or slightly smaller outer diameter as that of the mouth closing portion 9 and a straw insertion portion 11 having a hole provided in the mouth closing portion 9. In this case, the same operation and effect as those of the first embodiment can be obtained. In addition, when the beverage is not drunk, the original lid of the beverage container 1 is attached to the mouth 3 with the lid 5 for the beverage container attached to the mouth 3. Can be mounted on
