Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container lid provided with a flexible outflow pipe, which is applied to a container containing a beverage, and more particularly to a marathoner who is sick while lying on a bed. The present invention relates to a container lid suitably used when drinking a drink while running, or when a person driving a bicycle or a car consumes a drink.

[0002]

2. Description of the Related Art Japanese Patent Publication No. Sho 42-12573 discloses a lid body attached to the mouth and neck of a container and an outer lid attached to the lid body. Are disclosed. The lid body has a main wall that covers the top surface of the mouth and neck of the container. A through hole is formed in the main wall, and a flexible outflow tube extending from the periphery of the through hole is integrally formed. The outer lid is rotatably mounted on the lid body. Such an outer lid has a top wall and a cylindrical side wall hanging from the periphery of the top wall. An opening is formed in the side wall. When the outer lid is positioned in the open position, that is, when the opening formed in the side wall is positioned at a predetermined angle, the outflow pipe provided in the lid body extends outward through the opening of the outer lid. Can be Therefore, for example, the beverage contained in the container can be ingested by holding the tip of the outflow pipe in the mouth and sucking it. When the outer lid is rotated in an appropriate direction from the open position, the side wall of the outer lid acts on the outflow pipe, whereby the outflow pipe is appropriately bent and housed in the side wall of the outer lid.

[0003]

However, the conventional container lid as described above has the following problems to be solved. First, for example, a container lid in which the lid body is screwed to the mouth and neck of the container, more specifically, an external thread is formed on the outer peripheral surface of the mouth and neck of the container, and the peripheral edge of the main wall is formed on the lid body. A skirt wall hanging from the skirt wall is formed, and a female thread is formed on the inner peripheral surface of the skirt wall. The female thread is screwed onto the male thread to form a lid body on the mouth and neck of the container. In the case of a container lid of a form to be attached, when attaching the container lid to the mouth and neck of the container, it is necessary to rotate the container lid with respect to the mouth and neck of the container. Even when rotating, the lid body is covered with the outer lid, so that only the lid body cannot be rotated in the required direction. When the outer lid is rotated, the outer lid is rotated with respect to the lid main body and positioned at the open position, and as a result, a situation occurs in which the protruding tube is protruded outward. Because of this, it cannot be applied to a container lid in which the lid body is screwed to the mouth and neck of the container.

[0004] Second, the opening formed in the outer lid remains open without being closed even when the outer lid is placed in the closed position. Therefore, there is a possibility that dust or the like may enter the inside of the container lid through the opening, which is not sanitary.

Third, the outer lid is closed from the open position, particularly when the extension length of the outflow tube is made relatively long so that the user can easily grip the tip of the outflow tube. There is a tendency that the outflow pipe cannot be bent sufficiently smoothly when rotated into position. If the outflow pipe is formed integrally with the lid body, the flexibility of the outflow pipe is limited due to the rigidity required for the lid body, and it becomes more difficult to smoothly bend the outflow pipe.

The present invention has been made in view of the above-mentioned facts, and the main technical problem is that a problem particularly arises in a container lid in which a lid body is screwed onto the mouth and neck of the container. Applicable without sacrifice, the opening for extending the outlet tube is substantially closed when the beverage is not consumed, and the outlet tube is bent sufficiently smoothly even if the extension length of the outlet tube is relatively long. SUMMARY OF THE INVENTION It is an object of the present invention to provide a container lid with a new and improved flexible outflow tube, which solves the above first, second and third problems.

[0007]

Means for Solving the Problems As a result of intensive studies, the inventors of the present invention have found that a unique lid body attached to the mouth and neck of a container, a unique upper lid and a unique lid combined with the lid body.

It is arranged corresponding to.

Continuing the description with reference to FIGS.
The shutter member 8 has a cylindrical shutter wall 80.
The shutter wall 80 is formed with a sub-arc opening 82 extending in an arc shape in the circumferential direction. It is preferable that the length of the sub-arc opening 82 in the circumferential direction be in the range of 30 to 50 degrees. The sub-arc opening 82 in the illustrated embodiment extends to the lower edge of the shutter wall 80, but does not extend to the upper edge of the shutter wall 80, so that the shutter wall 80 has It extends continuously in the circumferential direction without interruption. The thickness of the shutter wall 80 corresponds to the distance between the protruding wall 60 and the annular projection 70 on the upper lid 6. As can be clearly understood by referring to FIG. 3 in conjunction with FIG. 1, the outer peripheral surface of the shutter wall 80 protrudes radially outward, adjacent to one end of the sub-arc opening 82, and then extends along the shutter wall 80. An operation piece 84 extending in an arc shape is provided. On the outer surface of the operation piece 84, irregularities 86 are formed.

The lid body 4, the upper lid 6, the shutter member 8, and the flexible outflow pipe 10 in the illustrated embodiment are combined as follows, for example. First, one end of the flexible outflow tube 10, which may be elongate cylindrical, is connected to the horizontal portion 54 of the extension tube 50 in the lid body 4 as clearly shown in FIG.

Of the horizontal part 54 is formed on the outer peripheral surface of the horizontal part 54. As can be understood by referring to FIGS. 2 and 3, the shutter member 8 is configured such that the shutter wall 80 is positioned outside the annular protrusion 44 formed on the upper surface of the main wall 14 of the lid body 4, 3 is rotatably combined with the lid body 4 at a closed position indicated by a solid line and an open position indicated by a two-dot chain line in FIG. In the closed position shown by the solid line in FIG. 3, the outer surface of a portion of the operation piece 84 of the shutter member 8 extending in the radial direction comes into contact with one end of the side wall 32 of the lid body 4, whereby the shutter member 8 is further moved in FIG. Clockwise rotation is prevented. In the open position shown by the two-dot chain line in FIG. 3, the inner surface of the radially extending portion of the operation piece 84 of the shutter member 8 abuts on the other end of the side wall 32 of the lid main body 4, whereby the shutter member 8 At 3, further rotation in the counterclockwise direction is prevented.

Continuing the description with reference to FIGS. 2 and 3,
The upper lid 6 is assembled with the lid main body 4 and the shutter member 8 by positioning the side wall 62 between the side wall 32 of the lid main body 4 and the shutter wall 80 of the shutter member 8. The lower edge of the side wall 62 of the upper lid 6 is inserted into a receiving groove 42 formed in the main wall 14 of the lid body 4, and a locking piece 38 formed on the upper edge of the side wall 32 of the lid body 4. Is inserted into a locking groove 68 formed in the protruding wall 60 of the upper lid 6, and the lid body 4
The ridge 66 formed on the outer peripheral surface of the side wall 62 of the upper lid 6 is engaged with the groove 40 formed on the inner peripheral surface of the side wall 32 of the upper lid 6, and thus the upper lid 6 is in contact with the lid main body 4. Fixed to the required relationship. As can be clearly understood by referring to FIG. 3, the main arcuate opening 34 formed in the side wall 32 of the lid body 4 and the main arcuate opening 64 formed in the side wall 62 of the upper lid 6 are aligned with each other. It is located. The rotation of the upper lid 6 with respect to the lid main body 4 is prevented by the side wall 62 of the upper lid 6 being restrained between the restraining pieces 36 disposed at both ends of the side wall 32 of the lid body 4. When the upper lid 6 is combined as required after the outlet pipe 10 and the shutter member 8 are combined with the lid main body 4, three guide pillars 72 hanging down from the top wall 58 of the upper lid 6 as clearly shown in FIG.
The lower end of the regulating column 74 is inserted into each of the four column receiving projections 46 formed on the main wall 14 of the lid main body 4. In addition, a contact column 78 disposed on the lower surface of the top wall 58 of the upper lid 6 is brought into contact with the upper surface of the upright portion 52 of the extension tube 50 disposed on the lid main body 4. Therefore, when the upper lid 6 is combined with the lid body 4 as required, the force applied to the top wall 58 of the upper lid 6 is transmitted to the lid body 4 via the contact pillar 78 together with the guide pillar 72 and the regulating pillar 74. Can be
As clearly shown in FIG. 3, a pair of restraining columns 76 hanging down from the top wall 58 of the upper lid 6 connect one end of the outflow pipe 10 fitted to the horizontal section 54 of the extension pipe 50 to the horizontal section 54. Behind the formed locking ridge 56 (upward in FIG. 3)
Thus, accidental detachment of the outflow tube 10 from the extension tube 50 is sufficiently reliably prevented.

When the shutter member 8 combined with the lid body 4 and the upper lid 6 is located at the open position shown by a two-dot chain line in FIG.
The sub-arc opening 82 formed at 0 is positioned so as to overlap with the main arc opening 34 formed at the side wall 32 of the lid main body 4 and the main arc opening 64 formed at the side wall 62 of the upper lid 6. ing. And the flexible outflow pipe 10
3 extends substantially straight following the horizontal portion 54 of the extension tube 50 as shown by a two-dot chain line in FIG. 3, and extends along the main arcuate opening 64 of the upper lid 6, the main arcuate opening 34 of the lid body 4 and the shutter member 8 Through the sub-arc-shaped opening 82. When the shutter member 8 is rotated clockwise in FIG. 3 from the open position shown by the two-dot chain line in FIG. 3 to the closed position shown by the solid line in FIG.
The shutter wall 80 of the shutter member 8 acts on the extended portion of the outflow tube 10, and sequentially cooperates with each of the three guide columns 72 to gradually bend the extended portion of the outflow tube 10. When the shutter member 8 is rotated to the closed position shown by the solid line in FIG.
The sub-arc opening 82 formed in the shutter wall 80 is covered by the side wall 32 of the lid main body 4 and the side wall 62 of the upper lid 6, and the main arc opening 34 of the lid main body 4 and the main arc opening 64 of the upper lid 6 are shutter members. 8 is closed by the shutter wall 80. And the outflow pipe 1 whose extension part is gradually bent
Reference numeral 0 denotes the entirety of the lid body 4, the upper lid 6, and the shutter member 8.
Is housed in the space surrounded by. As clearly shown in FIG. 3, each of the three guide columns 72 and the shutter wall 8
Between zero and the outflow tube 10 is crushed. When the shutter member 8 is rotated counterclockwise in FIG. 3 from the closed position indicated by the solid line in FIG. 3 to the open position indicated by the two-dot chain line in FIG. 3, the sub-arc opening 82 of the shutter wall 80 causes the main arc of the lid main body 4 to rotate. Overlapping the opening 34 and the main arcuate opening 64 of the top lid 6, the flexible outflow tube 10 is sequentially opened from the shutter wall 80 from its distal end, and again shown by the two-dot chain line in FIG. 3 by its own elastic restoring force. As shown in the drawing, the second portion extends substantially straight following the horizontal portion 54 of the extension pipe 50, and extends outward through the main arc opening 64 of the upper lid 6, the main arc opening 34 of the lid body 4, and the sub arc opening 82 of the shutter member 8. It is returned to the state of extending. When the shutter member 8 is rotated from the closed position to the open position, the restricting column 74 disposed on the upper lid 6 causes the extended portion of the outflow pipe 10 to move excessively with the movement of the shutter wall 80. 3 to prevent the state from being moved further rightward in FIG. 3 beyond the state shown by the two-dot chain line in FIG. In the illustrated embodiment, both the lid body 4 and the upper lid 6 are provided with the side walls 32 and 62 in which the main arc-shaped openings 34 and 64 are formed. Either one of the walls 62 can be omitted.

Referring to FIG. 1 and FIG. 2, the illustrated container lid 2 also includes an inner stopper 12, which is attached to the lid body 4 prior to applying the container lid 2 to the mouth and neck of the container. The stopper 12 is combined. The inner plug 12 includes a circular bottom wall 88 and a cylindrical side wall 90 extending upward from the periphery of the circular bottom wall 88. A pull ring 92 is provided on the inner peripheral surface of the side wall 90.
Is connected. An annular flange 94 protruding outward in the radial direction is formed at the upper end of the outer peripheral surface of the side wall 90, and a thin flange 95 projecting radially outward from the upper end edge of the annular flange 94 is further formed. The inner plug 12 is relatively weak, in other words, easily detached with a small force by elastically locking the thin-walled flange 95 to the upper end of the inner peripheral surface of the skirt wall 16 of the lid body 4. So that it can be carried out.

Referring to FIG. 7 together with FIGS. 1 to 3, the container lid 2 in which the inner stopper 12 is combined and the shutter member 8 is located in the closed position is made of a suitable synthetic resin such as polyethylene terephthalate. Attached to the mouth and neck 98 of a container 96 that can be formed from resin. The mouth and neck 98 of the container 96 has a substantially cylindrical shape, and has a male thread 100 and a locking jaw 102 located below the male thread 100 on the outer peripheral surface. The container lid 2 is attached to the mouth and neck 98 by fitting the lid main body 4 to the mouth and neck 98 and rotating it in the closing direction, ie, clockwise as viewed from above in FIGS. 2 and 7. At this time, for example, the side wall 32 of the lid body 4 is gripped by the rotary chuck of the lid tightening machine, which may be a known form, and the lid body 4 (therefore, the upper lid 6, the shutter member 8, the outflow pipe 10 and The inner stopper 12 can also be rotated in a predetermined direction. A female thread 24 formed on the inner peripheral surface of the main part 20 of the skirt wall 16 of the lid body 4 is screwed into the male thread 100 of the mouth-neck part 98 and formed on the tamper-evident foot 22. The locking means 26 is elastically deformed, passes through the locking jaw 102, and is locked below it. Inner plug 1 combined with lid body 4
2, the outer peripheral surface of the side wall 90 is closely contacted with the inner peripheral surface of the mouth-neck portion 98.

For example, when drinking the contents of the container 96, which is a liquid beverage, the user puts a finger on the side wall 32 of the lid body 4 and rotates the container lid 2 in the opening direction, that is, in the counterclockwise direction as viewed from above in FIG. Let me know. Thus, since the female thread 24 of the lid body 4 is moved along the male thread 100 of the mouth and neck 98, the lid body 4, the upper lid 6, the shutter member 8 and the outflow are removed except for the tamper-evident foot 22. The tube 10 is raised with rotation. On the other hand, the tamper-evident hem 22 of the lid body 4 is provided with the locking means 26 by the locking jaw 10 of the mouth and neck 98.
2 is prevented from moving upward, and thus the breakable line 18 formed in the skirt wall 16 is broken, and the tamper-evident hem 22
Is separated from the main part 20 of the skirt wall 16. Such a break in the breakable line 18 clearly indicates that the container lid 2 has been operated and compensates for the so-called tamper-evident properties. Leave the tamper evidence hem 22
Other parts of the lid body 4, the upper lid 6, the outflow pipe 10, and the shutter member 8 are separated from the mouth and neck. On the other hand, since the inner plug 12 is combined with the lid main body 4 so as to be easily detached with a small force as described above, the inner plug 12 is detached from the lid main body 4 and remains in the mouth and neck portion 98. Thereafter, the user puts his / her finger on the pull ring 92 to detach the inner plug 12 from the mouth and neck 98 and open the mouth and neck 98. Then, plug 1
The container lid 2 is attached again to the mouth and neck 98 from which the 2 has been detached, that is, the lid body 4 is fitted to the mouth and neck 98 and rotated in the closing direction,
Female thread 24 formed on skirt wall 16 of lid body 4
Into the male thread 100 of the mouth and neck 98. Then, as shown in FIG. 8, the annular ridge 30 formed on the lower surface of the main wall 14 of the lid body 4 is brought into contact with the top surface of the mouth and neck 98, thereby sealing the mouth and neck 98. Is done. Thereafter, the operation piece 84 of the shutter member 8 (FIGS. 1 and 3)
3 is rotated counterclockwise in FIG. 3 from the closed position shown by the solid line in FIG. 3 to the open position shown by the two-dot chain line in FIG. Thus, as described above, the sub-arc opening 82 of the shutter member 8 overlaps with the main arc opening 34 of the lid body 4 and the main arc opening 64 of the upper lid member 6, and the outflow pipe 10 is sequentially opened from the front end of the shutter member. 3, and extend substantially straight as shown in FIG. 8 by the two-dot chain line in FIG. 3 and the main arc opening 64 of the upper lid 6, the main arc opening 34 of the lid body 4, and the shutter member. 8
Through the sub-arc opening 82 of FIG.
When the outflow pipe 10 is shown in FIG. 3 by a two-dot chain line and also in the state shown in FIG. 8, the blockage due to the bending is released. Therefore, the beverage contained in the container 96 can be swallowed by holding the tip of the outflow pipe 10 in the mouth and sucking it. The outflow tube 10 is extended sufficiently long so that its tip can be easily gripped. If desired, the main portion of the container 96 may be somewhat crushed to facilitate draining the beverage from the container 96. After drinking the required amount of beverage, a finger is put on the operation piece 84 (FIGS. 1 and 3) of the shutter member 8 to move from the open position indicated by the two-dot chain line in FIG. 3 to the closed position indicated by the solid line in FIG. In FIG. 3, it is rotated clockwise. Thus, as described above, the shutter wall 80 acts on the extended portion of the outflow pipe 10 and cooperates with the three guide columns 72 in order to gradually bend the extended portion of the outflow pipe 10. Thus, although the outflow pipe 10 is relatively long, it is gradually and smoothly bent, and the side wall 32 of the lid body 4 and the side wall 62 of the upper lid 6 together with the main wall 14 of the lid body 4 and the top wall 58 of the upper lid 6. The shutter member 8 is housed in a space surrounded by a shutter wall 80. The outflow tube 10 is crushed between the shutter wall 80 and the three guide posts 72, so that the discharge of the contents through the outflow space 10 is sufficiently tightly sealed, and a sufficient seal is maintained even when an impact is applied. Is done. The sub-arc opening 82 of the shutter member 8 is closed by the side wall 62 of the upper lid 6 and the side wall 32 of the lid main body 4, and the main arc opening 34 of the lid main body 4 and the main arc opening 64 of the upper lid 6 are closed by the shutter member 8. It is closed by the shutter wall 80. Therefore, the space in which the outflow pipe 10 is stored is closed from the outside, and dust and the like are prevented from adhering to the outflow pipe 10 when not in use.

9 can be pivoted. Top lid 20
In FIG. 6, the restraint columns 76 and the contact columns 78 provided on the upper lid 6 in the above-described embodiment are omitted (see FIGS. 2 and 6). Other configurations of the upper lid 206 are substantially the same as the upper lid 6 in the above-described embodiment. On the other hand, as shown in FIG.
In the upper edge of the shutter wall 280, a lock notch 213 is provided.
Are formed. When the shutter member 208 is positioned at the closed position shown by the solid line in FIG. 11, the engagement projection 211 formed at the tip of the lock piece 203 is moved to the shutter wall 2.
The shutter member 208 is engaged with the engaging notch 213 of the shutter 80, thereby locking the shutter member 208 in the closed position, and reliably preventing the shutter member 208 from accidentally rotating from the closed position. When the base end of the lock piece 203 is pressed and turned to the unlock position shown by the two-dot chain line in FIG. 11, the lock of the shutter member 208 is released, and the shutter member 208 is moved from the closed position shown by the solid line to the two-dot chain line. Movement to the open position shown is permitted.
