Description

  The present invention is an attachment for drinking and drinking straws attached to the mouth or neck of a plastic bottle such as a plastic bottle for containing beverages, and a straw with bellows is inserted into the attachment for sucking the beverage in the bottle. The present invention relates to an attachment for attaching a straw that can be used for drinking.

There are several proposals related to such straw-mounted attachments.
For example, Patent Document 1 relates to a cap that can store a bendable straw, and can be screwed into a mouth portion of a drinking water bottle main body using a screw on the outer periphery thereof. An inner plug disposed directly above the screw formed on the inside of the cap, the inner plug having two holes into which a main body portion and a drinking mouth portion of the straw can be inserted, and the cap via a hinge. And a lid that can be freely opened and closed.

  According to the cap of this patent document 1, when drinking water containing a plastic bottle is purchased, it can be easily set in the mouth of the plastic bottle, and a commercially available bendable straw is used to Can drink and drink drinking water. After drinking, the upper opening can be closed with the straw contained in the cap.

  That is, the cap of Patent Document 1 can be screwed onto the mouth using a screw formed on the outer periphery after the lid is removed from the mouth of the PET bottle. When installed in this manner, the inner stopper of the inside comes into contact with the upper end of the mouth of the PET bottle, and as described above, a commercially available straw is inserted into one of the two holes to suck the inside beverage. You will be able to drink. On the other hand, after finishing drinking, after the upper part is bent and the drinking side is inserted into the other hole of the inner plug while the suction part side of the straw is inserted into one hole of the inner plug, It is also possible to keep the mouth of the plastic bottle closed by covering the cap with an upper opening of the cap.

  However, the cap of this Patent Document 1 is configured so that the inner stopper is configured on the inside of the cap, and the cap is attached to the mouth portion of the plastic bottle, and has a configuration with a sense of incongruity protruding slightly higher from the mouth portion, The upper opening of the cap is closed with a lid attached via a hinge, but it is only closed with a one-touch type, and it must be said that there is anxiety about watertightness. That is, there is a possibility that the beverage stored when the plastic bottle is overturned leaks to the outside. Further, since the lid attached to the plastic bottle is not used, it must be discarded before the use of the plastic bottle itself is finished, which is troublesome and wasteful.

  Patent Document 2 relates to a straw storage one-touch cap, which has a screw part on the inner periphery, and is configured to be screwable so that it can be screwed into the mouth part of the PET bottle with the screw part on the outer periphery. A main body and an inner stopper configured near the upper upper end of the cap body, the inner stopper opening two straw holes into which the main body portion of the straw bellows and the vicinity of the drinking mouth can be inserted, and the cap body And a one-touch cap portion that closes an upper opening portion that is coupled to a part of the upper end via a hinge.

  The straw storage one-touch type cap of Patent Document 2 has almost the same configuration as the cap capable of storing the straw of Patent Document 1, except that the position of the inner plug is the height direction of the cap in Patent Document 1. In contrast to being positioned at the middle portion, Patent Document 2 is only provided at the upper portion, which is not a substantial difference. Therefore, the straw storage one-touch cap of Patent Document 2 can be used in the same manner as the cap capable of storing the straw of Patent Document 1, and can be said to have the same problems. .

  Patent Document 3 relates to a hybrid bottle, and includes a container body having a heat insulating structure for containing a beverage and a drinking port for direct drinking having a liquid passage leading to the inside of the container body at the container port of the container body. A first hole opened in a drinking mouth part and a partition plate arranged in the middle of the liquid passage in the vertical direction, and accepts and supports a dedicated straw provided with a projecting action part so as to appear and remove. The first hole is connected to both sides of the first hole, and on one side, the suction part below the bellows part of the ready-made straw is removably received and supported, and on the other side, the bellows part is bent so as to protrude upward and downward. The second and third holes for receiving the sucked mouth so that it can be inserted and removed and held in the retracted state, and the ends of the partition plate in the direction perpendicular to the second, first and third holes arranged in series Two auxiliary holes opened , And can be used for direct drinking without a straw, sucking and drinking using a dedicated straw, and sucking and drinking using a ready-made straw with a bellows, and the drinking mouth portion has a lid for closing it. Attached.

  Therefore, according to this hybrid bottle, direct drinking without using a straw from the mouth of the drinking mouth, sucking and drinking using a dedicated straw placed in the first central hole, both sides of the first hole It is possible to freely perform any of the sucking and drinking using a ready-made straw with a bellows inserted into one of the second and third holes arranged in the.

  However, this hybrid bottle is a bottle in which a large number of the above-mentioned components that are unclear whether or not they are necessary for all users are pre-installed in a complicated positional relationship, and some users do not need a mouthpiece for direct drinking Or, it is not necessary to suck and drink with a dedicated straw or a ready-made straw, and there are cases where unnecessary components are bothersome. There is also the problem of increasing costs due to unnecessary elements. Therefore, the hybrid bottle of Patent Document 3 is inappropriate in terms of cost when applied to a plastic bottle for beverages such as a disposable plastic bottle.

  Moreover, in the hybrid bottle of Patent Document 3, a partition plate is arranged in the middle of the liquid passage of the container mouth, and the first to third holes are opened in the partition plate. It is extremely inappropriate to provide a partition plate in the middle of the mouth in the vertical direction, and to open a hole or vent for inserting a straw in the mouth so that only drinking and drinking with a straw can be made. Yes, it seems difficult to adopt. It seems to lack practical utility.

  The present invention is an attachment for drinking and drinking straws that can be easily attached to the mouth or neck of a disposable plastic bottle such as a plastic bottle containing various beverages, and the bellows is directly under the mouth. It is possible to insert the ready-made straw provided in a state where it does not rotate unnecessarily, and in the inserted state, it is naturally possible to suck and drink the beverage in the bottle. It is possible to provide an attachment for wearing a straw that can be closed with the original lid attached to the PET bottle, and further, when drinking due to illness or any other reason. Even if the person who cannot wake up is lying down, it is possible to drink without spilling the beverage from the plastic bottle. It is an object of the resolution is to provide a straw mounting attachment that.

A first aspect of the present invention is a mounting cylindrical body for tightly inserting and fixing in a mouth portion of a plastic bottle to be mounted between its inner periphery and a downward taper whose outer diameter decreases in a downward direction. A mounting cylinder configured in a shape;
Constructed in the lower part of the inside of the mounting cylinder, an inner plug part for partitioning the upper and lower sides,
It is a straw hole to insert the suction side of the straw with bellows opened in the inner plug part, it has a tapered shape with a smaller diameter downward, and the inserted straw is rotated unnecessarily at the lowest diameter part at the bottom A straw hole that can be held in close contact
It is a drinking hole that inserts the drinking mouth side of the straw that is opened in the inner plug part, and when the drinking mouth side of the straw is inserted, a drinking hole having a diameter that creates a gap between the outer periphery thereof,
It is the attachment for straw wearing comprised.

2 of the present invention is an attachment for attaching a straw according to 1 of the present invention,
A tube body having a length that can be bent into the drinking hole, can be inserted into the drinking hole side of the straw after drinking, and extends to a height that exceeds the upper end of the mouth of the plastic bottle to be attached. Closely inserted and fixed.

3 of the present invention is an attachment for attaching a straw according to 1 of the present invention,
The upper surface of the inner plug portion is configured as a descending inclined surface that descends toward the drinking hole.

  According to the attachment for attaching a straw of 1 of the present invention, after this is closely inserted into the mouth of a plastic bottle such as PET for beverages, the suction side of the straw with bellows is inserted into the straw hole, It can be usefully used for sucking and drinking beverages in the plastic bottle using the straw.

  Moreover, according to the attachment for straw attachment of 1 of this invention, as above-mentioned, this can be closely inserted and fixed to the opening part of the plastic bottle for drinks. Furthermore, this dense charging can be performed easily and reliably. That is, the mounting cylinder has an outer diameter corresponding to the inner diameter of the mouth of the target plastic bottle, and a tapered outer shape having a smaller diameter downward from the uppermost part. Therefore, grasp this with fingers and insert it into the mouth of the plastic bottle from the lower end, and insert the mounting cylinder with the fingers until the upper end of the plastic bottle matches the upper end of the mouth of the plastic bottle. be able to. Thereafter, the lid attached to the plastic bottle is closed by screwing the lid to the mouth, and the mounting cylinder is inserted and fixed to the mouth to the required depth. One straw mounting attachment can be inserted and fixed in the mouth of a plastic bottle.

  In short, according to the attachment for attaching a straw according to one aspect of the present invention, the attachment cylindrical body is pushed and inserted into the mouth of the plastic bottle with the fingers until the upper end coincides with the upper end of the mouth of the plastic bottle. The attachment cylinder is mounted and fixed in the mouth of the plastic bottle to a predetermined depth by a very simple operation of simply screwing and covering the attached lid on the mouth, and the attachment for attaching the straw It is possible to complete the attachment to the mouth of the.

  Further, as described above, the attachment for attaching a straw of the present invention is such that the mounting cylinder is placed and fixed in the mouth portion of the target plastic bottle, and there is no portion protruding outside. Further, as described above, the lid that closes the mouth part is also used as it is originally attached to the plastic bottle. If the mouth part is a transparent body, the inner mounting cylinder is slightly Apart from being able to see through, there is no change in appearance.

  As described above, after the attachment for attaching a straw of the present invention 1 is set in the mouth portion of a plastic bottle, the sucking side of the straw is inserted into the straw hole of the inner plug portion, whereby the beverage in the plastic bottle It is possible to perform sucking and drinking with the straw. Inserting the straw into the straw hole is easy because the straw hole opens in a taper shape that spreads upward, while the lowermost part of the straw hole has the straw attached to the exterior. Since the diameter is held, the inserted straw is held in a fixed state in the straw hole and does not rotate unnecessarily. Therefore, when the drinking side is tilted in a desired direction at the bellows portion, there is no need for a troublesome operation in which the direction changes uselessly and the direction must be corrected. After sucking and drinking, the drinking mouth side of the straw is folded in an inverted U shape at the bellows part, inserted into the drinking hole, and the original lid attached to the plastic bottle is screwed into the mouth part of the plastic bottle. If the outer packaging is used, the plastic bottle can be closed with the straw stored in the plastic bottle.

  That is, by appropriately setting the height direction dimension of the mounting cylinder, the size of the internal space defined by the upper surface of the inner plug portion and the inner periphery of the mounting cylinder is appropriate. Then, by folding back as described above and inserting the mouth side into the mouth hole, it becomes possible to fit the portion above the middle plug portion of the straw into the space. Therefore, it is not necessary to take out the straw after drinking and drinking with the straw. There is no problem with storage of the straw until drinking of the plastic bottle is completed.

  In addition, according to the attachment for attaching a straw of the first aspect of the present invention, as described above, since the attachment attached to the target plastic bottle is used as the lid, the mouth portion is If the lid is closed, it is not easy for the beverage inside to leak even if the lid is knocked down.

  Furthermore, when the mouth of the plastic bottle is closed with the attached lid as described above, and when the bottle is tilted as described above, a part of the lower beverage is placed above it through the drinking hole. Although there is a possibility of fluid movement, since the diameter of the drinking hole is formed larger than the outer diameter of the straw, if the plastic bottle is set up, it will easily return to the lower container side through the drinking hole, There is no problem of spilling from the mouth when the lid is removed.

  According to the attachment for wearing a straw 2 of the present invention, it is possible for a drinker or the like having a bad physical condition to drink while lying down. For example, in such a case, the drinking hole is previously provided. By bending the upper part of the tube body inserted and fixed closely in the direction opposite to the direction in which the plastic bottle falls, there is no problem of spilling the beverage as its contents at the time of drinking. Further, after the end of drinking, if the drinking mouth side of the straw is inserted into the tube and bent as a whole in an inverted U shape, the plastic bottle is completely the same as in the case of the attachment for attaching a straw of 1 of the present invention. The straw and the tube can be stored in the mouth, and the mouth can be closed with the lid without any inconvenience.

  According to the attachment for attaching a straw of 3 of the present invention, since the upper surface of the inner plug portion is configured as a descending inclined surface that is inclined downward toward the drinking hole, the plastic bottle to which it is attached is inclined or the mouth portion is When the plastic bottle is erected, the beverage that has moved sideways in the closed state with the lid closed will naturally gather on the side of the mouthpiece hole and easily pass through it. Can flow down.

Sectional drawing which shows the attachment for straw mounting of the 2nd modification with respect to an Example.

  A mode for carrying out the invention will be described based on an embodiment with reference to the drawings.

  As shown in FIGS. 1 (a) to 1 (d), the attachment for attaching a straw according to this embodiment basically includes a mounting cylinder 1 having a downwardly tapered outer periphery, and the mounting cylinder 1. An inner plug portion 2 formed at the innermost lower portion, a straw hole 3 for inserting a suction side 7a of a straw 7 opened in a vertically penetrating state into the inner plug portion 2, and an upper and lower portion through the inner plug portion 2 in the same manner It is comprised with the spout hole 4 for inserting the spout side 7b of this straw 7 opened in the state.

  The mounting cylinder 1 is a plastic bottle to be mounted. In this embodiment, as shown in FIGS. 2 (a) and (b) to FIGS. 4 (a) and 4 (b), the mouth 6 of the plastic bottle 5 is used. This is a component for tightly inserting and fixing between the inner periphery and the outer periphery thereof, and as described above, the outer periphery is configured in a downward tapered shape having a smaller diameter downward. The mounting cylinder 1 itself is made of plastic. In the drawing, the taper shape of the outer periphery of the mounting cylinder 1 is drawn slightly emphasized for the purpose of visual understanding.

  The mouth part 6 of the plastic bottle 5 to be attached is standardized, and the screw part 6a and the inner diameter of the outer periphery of the mouth part 6 are all the same regardless of the size of the capacity. The outer diameter corresponding to the inner diameter of the mouth portion 6 is configured. As described above, the outer periphery of the mounting cylinder 1 is configured to have a taper shape with a smaller diameter toward the lower side. Therefore, the outer diameter of the mounting cylinder 1 is the pet at the bottom. It is configured to be slightly lower than the inner diameter of the mouth portion 6 of the bottle 5 and to coincide with the inner diameter of the mouth portion 6 at the upper end.

  As shown in FIGS. 1 (a) to 1 (d), the inner plug portion 2 is a plate-like member configured in the shape of its bottom at the innermost lower portion of the mounting cylinder 1, and the mounting cylinder 1 2 (a), (b), FIG. 3 (d) and FIGS. 4 (a) and 4 (b), the mouth portion 6 is set in the mouth portion 6 of the plastic bottle 5. It is a component which becomes a state like the plug body which closes. The inner plug portion 2 is integrally formed with the mounting cylinder 1 by plastic. As described above, in this embodiment, the inner plug portion 2 is configured at the lowermost portion of the mounting cylinder 1, but is not limited to the lowermost portion.

  As shown in FIGS. 1 (a) to 1 (d), the straw hole 3 is an opening for inserting the suction side 7a of the straw 7, and is configured as a tapered opening having a smaller diameter downward. It is. When the diameter of the lowermost part is made substantially equal to the outer diameter of the straw 7, the straw 7 is inserted into the straw hole 3, and the upper part is bent at the bellows part 7c, the weight balance can be increased by tilting the plastic bottle 5 or the like. Even if a change occurs, the straw 7 is prevented from causing unnecessary rotation. The purpose is to eliminate the need for troublesome operations such that the drinking mouth often rotates and changes its position and must be returned to its original position. Note that the tapered shape having a smaller diameter downward (larger diameter upward) is intended to facilitate the insertion of the straw 7 into the straw hole 3. The arrangement of the straw holes 3 is not particularly limited, but a position slightly closer to the outer peripheral side from the center is appropriate, and in this embodiment, such a positioning is performed.

  The drinking mouth hole 4 is an opening for inserting the drinking mouth side 7b of the straw 7 having the suction side 7a inserted into the straw hole 3 by folding it back into an inverted U-shape at the middle bellows portion 7c. As shown to a)-(d), in this Example, it opens to the position which becomes point-symmetrical with the straw hole 3 by making the center point of the said inside plug part 2 into a symmetrical point. Although not limited to this position, this vicinity is appropriate. The diameter of the drinking hole 4 is set to a size that creates a gap between the drinking hole side 7b of the straw 7 and the outer periphery of the drinking hole 7b. When the beverage in the plastic bottle 5 flows onto the inner stopper portion 2 when the target plastic bottle 5 is tilted, the beverage can easily return to the container if the plastic bottle 5 is set up. This is the purpose.

  The attachment for attaching a straw according to this embodiment is configured as described above. After setting the attachment to the mouth portion 6 of the plastic bottle 5 containing the beverage to be applied, the straw 7 is inserted into the straw hole 3. If the sucking side 7 a is inserted, the straw 7 can be used for sucking and drinking the beverage in the plastic bottle 5. Further, this attachment can be easily and reliably set on the mouth 6 of the target plastic bottle 5.

The attachment of the straw mounting attachment of this embodiment to the mouth portion 6 of the target plastic bottle 5 is performed as follows.
As shown in FIG. 3 (a), this attachment is placed directly above the mouth portion 6 of the plastic bottle 5 from which the lid body 8 has been removed, with the mounting cylinder 1 facing the mouth portion 6 toward the lower diameter side. And is inserted into the mouth 6 as it is, as shown in FIG. This can be done by inserting this into the mouth 6 in a state where the peripheral side of the mounting cylinder 1 is grasped, and further pushing the hand into the upper end side. Since the outer periphery of the mounting cylinder 1 is formed in a tapered shape, it can be inserted smoothly.

  Thereafter, as shown in FIGS. 3 (c) and 3 (d), the attached lid body 8 that was originally screwed on the mouth portion 6 of the PET bottle 5 is again attached to the mouth portion 6 on the outer periphery thereof. The outer package is screwed into the screw portion 6a. At this time, it protrudes in an annular shape from the upper inner surface of the lid body 8, and when the lid body 8 is screwed to the mouth portion 6, it adheres to the upper inner surface of the mouth portion 6 to ensure water tightness. The lower end of the projecting ring portion 8 a comes into pressure contact with the upper end of the mounting cylinder 1, and pushes down the mounting cylinder 1 as the lid body 8 is screwed. As shown in FIG. 3 (d), when the lid body 8 is screwed until its upper inner surface comes into contact with the upper end of the mouth portion 6, the screwing exterior operation of the lid body 8 is completed. The push-down operation of the attachment inserted in 6 is also completed. Thus, as described above, the mounting cylindrical body 1 is pushed down at the lower end of the projecting ring portion 8 a of the lid body 8 and is fixed in the mouth portion 6. In addition, 8b in the figure is an annular residue separated from the lower end of the lid 8 when the lid 8 is removed from the mouth portion 6.

  As described above, the attachment for attaching the straw of this embodiment is set in the mouth portion 6 of the target plastic bottle 5, and thereafter, the straw body 8 is reversely rotated to remove it from the mouth portion. Sucking and drinking using 7 becomes possible.

That is, thereafter, as shown in FIG. 4 (a), the suction side 7a of the straw 7 is inserted into the straw hole 3 opened in the middle plug portion 2 of the attachment, and the inside of the PET bottle 5 is used by using the straw 7. Can drink and drink.
At this time, as shown in FIG. 4 (a), when the straw 7 is linear, the possibility that the straw 7 will rotate is low, but there will be no particular inconvenience for drinking even if it rotates. . However, when the straw 7 is slightly bent at the bellows portion 7c and the mouth side 7b is tilted toward the drinker for sucking and drinking, a change occurs in the weight balance of the straw 7 due to a slight inclination of the plastic bottle 5 or the like. If the straw hole 3 is not in a state of being in close contact with and holding the outer surface of the straw 7, the straw 7 rotates and the drinking mouth side 7 b changes its direction, and this is changed to the original position. If you don't return it, you will not be able to drink and the operation will be troublesome. However, since the straw hole 3 of this embodiment holds the straw 7 firmly at the lowermost part, the straw 7 does not rotate easily, and the direction of the drinking mouth side 7b is always constant. Can be kept in a state easy to drink.

  After sucking and drinking the beverage in the plastic bottle 5, as shown in FIG. 4 (b), the drinking mouth side 7b of the straw 7 is folded back into an inverted U shape at the middle bellows portion 7c, and the inside plug portion 2 and the attached lid body 8 is screwed on the mouth portion 6 of the plastic bottle 5 as shown in FIGS. 2 (a) and 2 (b). The plastic bottle 5 can be closed in a state where it is stored in the mouth 6 of the plastic bottle 5. The straw 7 can be easily stored.

  Furthermore, if the PET bottle 5 is tilted after the mouth portion 6 of the PET bottle 5 is closed with the attached lid body 8, there is a possibility that a part of the beverage may move particularly upward from the drinking hole 4. However, since the diameter of the drinking hole 4 is formed larger than the outer diameter of the straw 7, when the PET bottle 5 is stood, a part of the beverage easily returns to the lower container through the drinking hole 4. In other words, after removing the lid 8, there is no problem that the mouth 6 spills for some reason. In addition, as described above, when the plastic bottle 5 is tilted after the mouth part 6 is closed with the attached lid body 8, the beverage inside thereof may move to the mouth part 6 side. There is no further leakage from the mouth 6 to the outside. This is because the lid 6 that closes the mouth portion 6 is closed by using it originally attached to the plastic bottle 5.

  In addition, in the attachment for attaching a straw of this embodiment, the mounting cylindrical body 1 is in a charged state in the mouth portion 6 of the plastic bottle 5, and there are no components protruding outside the mouth portion 6. . Therefore, as described above, the mouth portion 6 can be closed with the lid body 8 originally attached to the plastic bottle 5, and therefore the plastic bottle 5 is transparent itself. It is only visible that the mounting cylinder 1 is present in the mouth portion 6, and before and after the mounting cylinder 1 is inserted and fixed, there are other differences in appearance. Absent.

  5 and 6 show a first modification of the attachment for attaching a straw according to the embodiment. In this embodiment, the lower part of the tube 9 with the bellows 9a is tightly inserted and fixed in the drinking hole 4 opened in the inner plug portion 2 of the attachment for attaching the straw of the embodiment. This is the same as the embodiment described in (1).

  That is, in this first modification, as shown in the figure, the lower part of the tubular body 9 is densely inserted and fixed in the drinking hole 4 of the inner plug portion 2. As shown in the figure, the tubular body 9 has a bending bellows portion 9a in the middle of the lengthwise direction, and the bellows portion 9a has a bellows portion 9a below the bellows portion 9a. An upper taper portion 9b having a smaller diameter toward the lower end is configured.

  The inner diameter of the tube body 9 is slightly larger than the outer diameter of the bellows-shaped straw 7, and the upper end of the tube body 9 has an upwardly tapered shape in order to facilitate insertion of the straw 7. The tube body 9 is inserted into the drinking hole 4 from below the inner plug portion 2. This insertion is performed from the upper end side of the tube body 9. As described above, the tapered portion 9b having a small diameter is formed below the bellows portion 9a toward the bellows portion 9a side. When inserted, as shown in FIG. 5A, the outer periphery of the tube body 9 is in close contact with the mouthpiece hole 4 in the middle of the tapered portion 9b and is in a fixed state.

  In this state, the tube body 9 is at a position where the upper end thereof slightly exceeds the upper end of the mounting cylinder 1, and the mounting cylinder 1 is inserted into the mouth of the PET bottle 5 as shown in FIG. In the state of being inserted and fixed to the portion 6, the upper end of the mouth portion 6 is positioned slightly beyond.

  Therefore, when drinking the beverage in the PET bottle 5, as shown in FIG. 5 (b), the suction side 7a of the straw 7 is inserted into the straw hole 3, and the upper end thereof is linear or the drinker side (FIG. 5 ( b) Bend it to the left) and drink. As shown in FIG. 5 (b), the tube body 9 is bent in advance to the side opposite to the drinker side using the bellows portion 9a.

  By bending the tube body 9 in this way, there is a risk that the drinker may spill the beverage in the plastic bottle 5 even when the drinker performs a drinking operation while lying down due to illness or other reasons. Absent. As described above, the suction side 7a of the straw 7 is inserted into the straw hole 3 and the outer periphery thereof is in close contact. Similarly, the tubular body 9 has a tapered portion 9b at the drinking hole 4. This is because the tube 9 is in an intimately attached state, and the upper portion of the tube body 9 can be bent to the side opposite to the drinker side as described above.

  After drinking, the straw 7 is slightly pulled up and bent into an inverted U-shape as shown in FIG. 6 (a) and inserted into the tube body 9 which has been returned to a straight line from the upper end. As shown in FIG. 6 (b), the tube 9 is bent so as to form an inverted U shape as a whole. In addition, the lid 6 can close the mouth portion 6 as described above.

FIG. 7 shows a second modification of the attachment for attaching a straw according to the embodiment.
This is a modification of the upper surface of the middle plug portion 2 of the attachment for attaching a straw of the embodiment, and the other points are all the same. That is, in this second modification, as shown in the figure, the upper surface of the inner plug portion 2 is configured as a descending inclined surface 2 a that descends toward the drinking hole 4. Accordingly, as described in the above embodiment, this is set inside the mouth portion 6 of the target plastic bottle 5, and the suction side 7a of the straw 7 is inserted into the straw hole 3 of the inner plug portion 2 so that the bellows In the case where the plastic bottle 5 is tilted or laid down after the mouth part 7b is folded and inserted into the mouth hole 4 and the mouth part 6 is closed with the lid 8 As described above, even if the outer periphery of the suction side 7 a of the straw 7 is in close contact with the straw hole 3, the beverage is gradually added through the straw hole 3 into which the straw 7 is inserted and through the drinking hole 4.
