Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a container lid with a flexible suction tube that can be held in the mouth to aspirate the contents of the container.
[0002]
[Prior art]
As a container lid for a beverage container, Japanese Utility Model Publication No. 1-27699, Japanese Utility Model Publication No. 2-16664, and Japanese Utility Model Application No. 3-30012 have a mouth for sucking the contents of the container. A container lid having a flexible suction tube that can be used is disclosed. Such a container lid includes a lid body attached to the container neck and neck and an openable / closable outer lid. The lid body has a main wall that covers the top surface of the container mouth neck, and a through hole is formed in the main wall, and the suction pipe extends from the through hole. The main wall of the lid main body is formed with a projecting wall projecting upward from the upper surface thereof, or the outer lid is formed with a hanging wall. When the outer lid is brought into the closed position that covers the main wall of the lid body, the suction pipe is bent by the action of the projecting wall or the hanging wall and covered with the outer lid. When the outer lid is positioned at the open position that exposes the main wall of the lid body, the action of the protruding wall or the hanging wall on the suction pipe is released, the bending of the suction pipe is eliminated, and the suction pipe extends in the required direction. . The user can ingest the contents of the container by holding the tip of the suction tube in his mouth and sucking. A container equipped with such a container lid is, for example, when a sick person who is sleeping on a bed takes a drink, when a marathon runner takes a drink while running, a person driving a bicycle or a car takes a drink. It is particularly advantageously used in some cases.
[0003]
[Problems to be solved by the invention]
Thus, the conventional container lid provided with the flexible suction tube has the following problems to be solved. First, the extension length of the suction tube is relatively short, and therefore it is not always easy for the user to grasp the tip of the suction tube. If the extension length of the suction tube is increased, the suction tube is not accommodated in the outer lid even if the outer lid is positioned in the closed position, and it becomes impossible to position the outer lid in the closed position.
Secondly, when the outer lid is positioned at the closed position, the suction pipe is bent, but the flow path in the suction pipe is closed due to the bending of the suction pipe, and the so-called seal is established by such blocking, and the container contents We are trying to prevent the leakage of things. However, since the seal is limited to a single bent portion, the seal is not always sufficient, and there is a risk that the contents may leak when a strong impact is applied due to dropping or the like.
[0004]
The present invention has been made in view of the above facts, and the main technical problem thereof is a new and improved container lid that solves both the first and second problems existing in the conventional container lid, that is, Although the suction tube can be easily stored in the outer lid when the outer lid is positioned at the closed position, the suction tube is sufficiently long when the outer lid is positioned at the open position. When the outer cover is extended and the outer lid is positioned at the closed position, the suction pipe flow path is sufficiently closed, and there is no risk of the contents leaking even if a relatively large impact is applied. And providing an improved container lid.
[0005]
[Means for Solving the Problems]
As a result of intensive studies, the present inventors have found that the main technical problem can be solved by configuring the suction tube to be bent at at least three locations when the outer lid is positioned at the closed position.
[0006]
That is, according to the present invention, the container lid for achieving the main technical problem includes a lid body attached to the container neck and neck, an openable / closable outer lid, and a flexible suction tube.
The lid body has a main wall that covers the top surface of the container neck, and the outer lid is selectively positioned at a closed position that covers the main wall and an open position that at least partially exposes the main wall. And
A through hole is formed in the main wall of the lid body, and the suction pipe extends from the through hole,
The main wall of the lid body is formed with a protruding wall protruding upward from the upper surface thereof,
The outer lid has a top wall and a hanging wall depending from the inner surface of the top wall,
When the outer lid is positioned in the closed position, the drooping wall of the outer lid is positioned between the through hole of the lid body and the protruding wall, and the suction pipe is first inserted into the drooping wall. And then bent upward by the cooperation of the hanging wall and the projecting wall and extending upward between the hanging wall and the projecting wall, and then the projecting wall and the projecting wall. The portion of the suction pipe that extends between the hanging wall and the protruding wall is crushed between the hanging wall and the protruding wall. ,
When the outer lid is brought into the open position, the hanging wall of the outer lid is retracted from between the through hole and the protruding wall, and the suction pipe extends upward beyond the upper end of the protruding wall. To
A container lid is provided.
[0007]
When the outer lid is made to a position in the closed position, the suction tube at least two bent portions, it is preferable that the flow path of the suction pipe due to bending is closed. Preferably, the outer lid has a cylindrical side wall depending from the peripheral edge of the top wall, and a predetermined portion of a lower end edge of the cylindrical side wall is pivotally connected to the lid main body. By swiveling about the predetermined portion of the edge as the pivot center, the closed position and the open position are selectively positioned, and the outer lid is swung by an angle α of 35 to 60 degrees from the closed position. And an open position restricting means for preventing the outer lid from being further swung when the outer lid is swung to the open position. When positioned, at least the tip of the suction tube extends along the lower edge of the outer lid and extends at an angle α with respect to the horizontal. The main wall of the lid body is formed with a locking wall protruding upward from the peripheral edge thereof, and when the outer lid is positioned in the closed position, the inner periphery of the lower end of the side wall of the outer lid is formed. When the outer lid is swung from the open position to the closed position, the surface is locked to the outer peripheral surface of the upper end portion of the locking wall of the lid body. It is preferable that a notch is formed in which the tip of the suction tube is moved from the outside to the inside of the locking wall. In this case, it is preferable that the lid body is provided with a closing piece that is movable between an operating position for closing the notch of the locking wall and a non-operating position for releasing the notch.
[0008]

On the other hand, the suction tube 8 having a long and thin tube shape is made of a material having sufficient flexibility and restoration property and appropriate slipperiness, for example, synthetic rubber such as silicone rubber or urethane rubber.
[0010]
1 to 4, the lid body 4 in the illustrated embodiment is connected to a circular main wall 10 that extends substantially horizontally and to the periphery of the main wall 10. A cylindrical side wall 12 is included. The side wall 12 has an upright wall 16 extending upward from the peripheral edge of the main wall 10 together with a skirt wall 14 depending downward from the peripheral edge of the main wall 10. On the outer peripheral surface of the side wall 12, irregularities 18 extending in the vertical direction are formed except for both side portions (left side portion and right side portion in FIG. 2). The upright wall 16 is formed with a substantially semicircular cutout 20 located in the upper half of the specific angle portion. The skirt wall 14 is formed with a breakable line 22 extending in the circumferential direction. The skirt wall 14 has a main portion 24 above the breakable line 22 and a tamper evidence skirt 26 below the breakable line 22. It is divided into. The breakable line 22 may be in a known form including a plurality of slits (grooves) extending in the circumferential direction at a slight interval and a plurality of bridging portions located between the slits. A female thread 28 is formed on the inner peripheral surface of the main portion 24 of the skirt wall 14. A plurality of locking means 30 are formed on the inner peripheral surface of the tamper evidence skirt 26. Each of the locking means 30 can be constituted by projecting pieces that are arranged at intervals in the circumferential direction and extend obliquely upward inward in the radial direction.
[0011]
On the main wall 10 of the lid body 4, a substantially cylindrical locking wall 32 extending upward from its peripheral edge is formed. As understood from FIGS. 1 to 3, a notch 34 extending from the upper edge to the lower edge is formed at a specific angle portion of the locking wall 32. The angular position of the notch 34 is aligned with the angular position of the notch 20 formed in the upright wall 16. Corresponding to the notch 34, the locking wall 32 is formed with a closing piece 36 extending from the lower end edge of the notch 34 to the left in FIGS. 1 and 2. The closing piece 36 is connected to the lower end edge of the locking wall 30 through a thin hinge piece 37, and a rectangular locking protrusion 38 is formed on the upper surface or the inner surface thereof. The circumferential width of the locking projection 38 is substantially the same as the circumferential width of the notch 34, and the length of the locking projection 38 is somewhat shorter than the length of the notch 34. A locking protrusion 40 bulging outward in the radial direction is formed at the upper end of the outer peripheral surface of the locking wall 32.
[0012]
A through hole 42 is formed at a predetermined position of the main wall 10 of the lid body 4, and a projecting cylinder 44 is formed on the main wall 10 so as to project substantially vertically upward from the periphery of the through hole 42. ing. The main wall 10 is also formed with a protruding wall 46 protruding upward from a position spaced apart from the through hole 42 and the protruding cylinder 44 by a predetermined distance. As can be understood by referring to FIGS. 1 and 3, constraining protrusions 48 are formed on both sides of the upper end portion of the protruding wall 46. The gap between the restraining protrusions 48 is set to be somewhat larger than the diameter of the suction pipe 8. On the main wall 10 of the lid body 4, a pair of contact pieces 50 located on both sides of the through hole 42 are further formed. The contact piece 50 extends upward from the main wall 10 and has a substantially L-shaped cross section. The rear surface of the contact piece 50, that is, the upper end of the right side surface in FIGS. 1 and 2, is an inclined surface that gradually inclines forward, and the front surface, that is, the left side surface in FIGS. It is an elongated surface that extends. On the lower surface of the main wall 10 is formed a protrusion 52 that may be a thin-walled cylinder that hangs downward. On the lower surface of the main wall 10, two annular ridges 53 positioned inside the protrusions 52 are further formed.
[0013]
1 to 4, the outer lid 6 is suspended from the top wall 54 and the peripheral edge of the top wall 54 (extends upward in the state shown in FIGS. 1 to 4). 56 and a hanging wall 58 depending from the inner surface of the top wall 54 (upper surface in the state shown in FIGS. 1 to 4) (extending upward in the state shown in FIGS. 1 to 4). The outer lid 6 has a free edge (upper edge in the state shown in FIGS. 1 to 4) of the cylindrical side wall 56 and a free edge or upper edge of the upright wall 16 on the side wall 12 of the lid body 4. Are integrally connected to the lid body 4 by thin-walled hinge pieces 60 disposed between them. As can be understood by referring to FIG. 4 in conjunction with FIG. 1, the depending wall 58 extends substantially perpendicular to the top wall 54. A pair of contact pieces 62 are formed on both sides of the tip of the hanging wall 58 (the upper end in the state shown in FIGS. 1 and 4). Two inclined surfaces 64 and 66 defining a substantially isosceles triangle shape are formed on one side (left side in FIG. 1) of each contact piece 62, and the other side (right side in FIG. 1) is flat. Surface. As will be apparent from the following description, the pair of contact pieces 62 cooperate with the pair of contact pieces 50 formed on the lid body 4 to move the opening of the outer lid 6 relative to the lid body 4 to a predetermined position. An open position regulating means for regulating is configured. On the free end portion (the upper end portion in FIGS. 1 to 4) of the inner peripheral surface of the side wall 56, a protrusion 68 extending in an arc shape is formed.
[0014]
In the illustrated embodiment, as shown by a two-dot chain line in FIG. 1, one end of the suction tube 8 is fitted into the protruding cylinder 44 of the lid body 4, and thus the suction tube 8 extends from the through hole 42. Is established. 5 and FIG. 6 together with FIG. 1, in the illustrated embodiment, an inner plug 70 is further combined with the lid body 4 before the container lid 2 is applied to the container. The inner plug 70 includes a circular bottom wall 72 and a cylindrical side wall 74 extending upward from the peripheral edge of the bottom wall 72. A tension ring 76 is formed on the upper surface of the bottom wall 72. A thin flange 78 protruding outward in the radial direction is formed at the upper end of the outer peripheral surface of the side wall 74. Such an inner plug 70 is relatively weak, in other words, by having its thin flange 78 elastically locked to the inner peripheral surface of the projection 52 formed on the lower surface of the main wall 10 in the lid body 4. Thus, the lid body 2 is held so that it can be easily detached with a small force.
[0015]
The outer lid 6 connected to the lid body 4 by the thin hinge piece 58 is shown in FIGS. 1 to 4 with the thin hinge piece 58 as the center after or before the inner plug 70 is combined with the lid body 4. From the molding position, it is swung closed to the closed position shown in FIGS. In such a closing movement, as understood by comparing and referring to FIGS. 1, 6, and 8, the inclined surfaces 64 of the pair of contact pieces 62 formed on the outer lid 6 are formed on the lid body 4. The contact pieces 62 and / or 50 are elastically deformed by interfering with the inclined surfaces of the formed pair of contact pieces 50, and the contact pieces 62 pass through the contact pieces 50. When the outer lid 6 is closed to the closed position shown in FIGS. 5 and 6, the protrusion 68 formed on the inner peripheral surface of the cylindrical wall 56 of the outer lid 6 is locked to the locking wall 32 of the lid body 4. The outer cover 6 is elastically locked to the locking protrusion 40 formed on the outer peripheral surface of the outer cover 6 so that the outer lid 6 is held in the closed position shown in FIGS. 5 and 6.
[0016]
As understood by comparing and referring to FIGS. 1, 6, and 8, when the outer lid 6 is pivoted and closed to the closed position, the hanging wall 58 of the outer lid 6 is formed on the main wall 10 of the lid body 4. The through-hole 42 and the projecting cylinder 44 are located between the projecting wall 46 and the projecting wall 46. In this case, first, the drooping wall 58 of the outer lid 6 acts on the flexible suction tube 8 to bend the suction tube 8 downward, and then the drooping wall 58 of the outer lid 6 and the lid main body 4. The main wall of the lid body 4 is bent upward by the cooperation with the projecting wall 46 of the cover body 4 and further bent downward again by the cooperation of the projecting wall 46 of the lid body 4 and the cylindrical wall 56 of the outer lid 6. 10 and the outer lid 6. When the suction pipe 8 is bent along the upper end of the protruding wall 46, the suction pipe 8 extends between the restraining ridges 48 of the protruding wall 46, thereby preventing lateral displacement. . In the illustrated embodiment, the suction tube 8 is bent three times as described above. Therefore, even if the suction tube 8 is made relatively long, the space between the lid body 4 and the outer lid 6 is sufficiently ensured. Can be stored. In addition, as shown by the numbers 80, 82 and 84 in FIG. 6, the suction tube 8 is closed due to the bending in each of the three foldings. Further, when the suction pipe 8 which is bent upward by the cooperation of the hanging wall 58 and the projecting wall 46 and extends along the projecting wall 46 extends upward along the projecting wall 46, reference numeral 86 in FIG. As shown, it is crushed between the hanging wall 58 and the protruding wall 46. Thus, as will be further described below, when the outer lid 6 is positioned in the closed position, the discharge of the contents through the suction tube 8 is sufficiently sealed. Further, in the illustrated embodiment, the closing piece 36 disposed on the lid body 4 is illustrated in FIGS. 5 and 6 from the non-acting position illustrated in FIGS. 1 to 4 with the thin hinge piece 37 as the pivot center. It is swung to the operating position, and the locking projection 38 of the closing piece 36 is forced into the notch 34 and elastically held there. Thus, the notch 34 that has been opened is closed by the closing piece 36, and the entire suction pipe 8 is covered.
[0017]
5 and 6, the container lid 2 in which the inner plug 70 is combined, the outer lid 6 is located in the closed position, and the closing piece 36 is in the active position is the polyethylene terephthalate. It attaches to the mouth-and-neck part 90 of the container 88 which can be formed from such an appropriate synthetic resin. The mouth and neck portion 90 of the container 88 has a substantially cylindrical shape, and a male thread 92 and a locking jaw portion 94 positioned below the male screw 92 are formed on the outer peripheral surface thereof. The container lid 2 is attached to the mouth-and-neck portion 90 by fitting the lid body 4 to the mouth-and-neck portion 90 and rotating it clockwise, as viewed from above in FIG. A female thread 28 formed on the inner peripheral surface of the main portion 24 in the skirt wall 14 of the lid body 4 is screwed into a male thread 92 of the mouth-and-neck section 90, and is formed on the tamper evidence hem section 26. The locking means 30 is elastically deformed, passes through the locking jaw 94, and is locked below it. In the inner plug 70 combined with the lid body 4, the thin flange 78 is brought into close contact with the upper end of the mouth and neck portion 90, and the outer peripheral surface of the side wall 74 is brought into close contact with the inner peripheral surface of the mouth and neck portion 90.
[0018]
For example, when drinking the contents of the container 88 which is a liquid beverage, a finger is put on the side wall 12 of the lid body 4 to rotate the container lid 4 in the opening direction, that is, counterclockwise as viewed from above in FIG. Thus, since the female thread 28 of the lid body 4 is moved along the male thread 92 of the mouth-and-neck part 90, the lid body 2, the outer lid 6 and the suction pipe 8 are removed except for the tamper evidence skirt 26. Raised with rotation. On the other hand, the tamper evidence skirt portion 26 of the lid body 4 is prevented from moving upward because the locking means 30 is locked to the locking jaw portion 94 of the mouth-and-neck portion 90, thus forming the skirt wall 14. The breakable line 22 is broken to separate the tamper evidence skirt 26 from the main portion 24 of the skirt wall 14. Such breakage of the breakable line 22 clearly indicates that the container lid 2 has been operated and compensates for so-called tamper evidence characteristics. The tamper evidence skirt 26 is left, and the other parts of the lid body 4, the outer lid 6 and the suction tube 8 are detached from the mouth-and-neck portion 90. On the other hand, since the inner plug 70 is combined with the lid body 4 so as to be easily detached with a small force as described above, it is detached from the lid body 4 and remains in the mouth-and-neck portion 90. After that, a finger is put on the pulling ring 76 to detach the inner plug 70 from the mouth-and-neck portion 90 to open the mouth-and-neck portion 90. Next, the container lid 2 is mounted again on the mouth-and-neck portion 90 from which the inner plug 70 has been removed, that is, the lid body 4 is fitted onto the mouth-and-neck portion 90 and rotated in the closing direction to form the skirt wall 14 of the lid body 4. The female thread 28 is screwed onto the male thread 92 of the mouth and neck portion 90. In this way, as shown in FIG. 8, the protrusion 53 formed on the lower surface of the main wall 10 of the lid body 4 is brought into contact with the upper end surface of the mouth-and-neck portion 90 of the container 88. Is sealed. Thereafter, the outer lid 6 is pivoted and opened with the thin hinge piece 60 as the pivot center. When the outer lid 6 is pivoted and opened by an angle α which may be about 35 to 60 degrees to the open position shown in FIGS. 7 and 8, a pair of outer lids 6 formed on the outer lid 6 as clearly shown in FIG. The inclined surface 66 of the contact piece 62 is brought into contact with the front surface of the pair of contact pieces 50 formed on the lid body 4, whereby the outer cover 6 is moved to the open position shown in FIGS. 7 and 8. Being further swung open beyond that is prevented.
[0019]
Thus, when the outer lid 6 is pivoted open to the open position shown in FIGS. 7 and 8, as can be understood by comparing FIGS. 6 and 8, the protruding wall 46 of the lid body 4 and The bending action and the crushing action on the suction pipe 8 by the hanging piece 58 of the outer lid 6 are released, and as shown in FIGS. 7 and 8, the suction pipe 8 has its main portion formed by its own elastic restoring force. It will be in the state extended along the free edge of the cylindrical wall 56 of six. In the elastic restoring action like the suction pipe 8, the suction pipe 8 acts on the closing piece 36, and this is changed from the working position shown in FIGS. 5 and 6 to the non-working position shown in FIGS. 7 and 8. Move it. If the elastic restoring action of the suction tube 8 is relatively gentle and is not sufficient to move the closing piece 36 from the operating position to the non-operating position, it is only necessary to put the finger on the closing piece 36 and move it to the non-operating position. . When the suction pipe 8 is brought into the state shown in FIGS. 7 and 8, the blocking due to bending and the blocking due to crushing are released. Therefore, the beverage contained in the container 88 can be drunk by sucking the tip of the suction tube 8 over the mouth. The suction tube 8 is extended sufficiently long and can therefore be easily gripped at its tip. If necessary, the main portion of the container 88 can be crushed somewhat to facilitate the discharge of the beverage from the container 88. After drinking the required amount of beverage, the outer lid 6 is pivoted and closed to the closed position shown in FIGS. Further, the closing piece 36 is returned to the operating position as necessary. Thus, as described above, the suction tube 8 is bent three times and closed due to the bending. In the illustrated embodiment, it is occluded due to each of the three folds, as indicated by the numbers 80, 82 and 84 in FIG. Further, when the suction pipe 8 which is bent upward by the cooperation of the hanging wall 58 and the projecting wall 46 and extends along the projecting wall 46 extends upward along the projecting wall 46, reference numeral 86 in FIG. As shown, when the outer cover 6 is crushed between the hanging wall 58 and the projecting wall 46, and thus the outer lid 6 is positioned at the closed position, the discharge of the contents through the suction pipe 8 is sufficiently reliably sealed, such as an impact. Even if this works, a sufficient seal is maintained. Further, when the closing piece 36 disposed on the lid body 4 rotates the thin hinge piece 37 to the operating position shown in FIGS. 5 and 6, the opened notch 34 is closed by the closing piece 36. The entire suction tube 8 is obscured.
[0020]
【The invention's effect】
In the container lid of the present invention, when the outer lid is positioned at the closed position, the suction tube can be stored in the outer lid sufficiently easily when the outer lid is positioned at the opened position. The suction tube is extended for a sufficient length. When the outer lid is positioned at the closed position, the flow path of the suction tube is sufficiently securely closed, and there is no possibility that the contents will leak even if a relatively large impact is applied.
