Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device for opening the lid of a liquid container, and particularly to a device for opening the lid of a portable beverage container such as a water bottle.

[Conventional technology and its problems]

The lids and stoppers of portable beverage containers such as water bottles are screw-type, so when opening and closing them, you have to grasp the container with one hand and operate the lid or stopper with the other hand, so you can use both hands. There is an inconvenience in having to use

Furthermore, since the lid of a water bottle with a straw is opened and closed by rotating or pushing up, there is the same inconvenience as in the case described above.

Due to this inconvenience, with conventional water bottles, it is not possible to drink while working with one hand while holding the water bottle with the other hand, or to drink while running.

Therefore, the object of this invention is to provide a lid opening device which eliminates the conventional inconvenience and allows opening and closing operations with one hand.

[Means to achieve the purpose]

In order to solve the above problems, this idea
In a lid opening device for a liquid container, a discharge port 3 is provided on the upper end surface 2 of a lid body 1, and an opening/closing lid 4 that covers the discharge port 3 is attached to the lid body 1 by a hinge 5. Valve body 6 that closes from
The support arm 7 of the valve body 6 is rotatably attached to the lower surface of the upper end surface 2, and a spring force is applied to the support arm 7 to bias the valve body 6 in the valve closing direction. An inclined surface 8 is provided that gradually rises from the mounting part of the lid toward the valve body 6, and an operating rod 11 is slidably inserted through a hole 10 provided in the peripheral wall 9 of the lid body 1, and its tip is provided with an inclined surface 8 that gradually rises from the mounting portion of the lid toward the valve body 6. An operating button 12 is provided on the outer end of the opening face 8, and a rack rod 13 provided integrally with the operating button 12 is engaged with a pinion 14 provided on the hinge 5 of the opening/closing lid 4. .

[Effect]

When the operating button 12 is pressed with the fingertip of the hand holding the container, the pinion 14 engaged with the rack rod 13 integrated therewith rotates, and the opening/closing lid 4 is opened.
At the same time, the operating rod 11 rides on the inclined surface 8 of the support arm 7 and gradually pushes it down against the spring force applied to the support arm 7, thereby separating the valve body 6 from the discharge port 3.
Allows liquid to be discharged.

When the finger is released from the operating button 12, the support arm 7 returns to its original position due to the spring force, and at the same time, the operating rod 11 retreats. This causes the pinion 14 to rotate in reverse, and the opening/closing lid 4 to close.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

The lid body 1 has a threaded portion 16 by which it is screwed to the container. A discharge port 3 is provided on the upper end surface 2 of the lid body 1 at a position offset from the center thereof, and a drinking spout 17 is provided upright around the discharge port 3.

An opening/closing lid 4 is rotatably attached to the opposite side of the lid main body 1 across the center from the discharge port 3 by means of a hinge 5. This opening/closing lid 4 covers the drinking spout 17 as well as the above-mentioned discharge port 3.

A valve body 6 having a gasket 18 is provided on the lower surface of the discharge port 3. The valve body 6 is supported by a support arm 7, and the end of the support arm 7 is connected to the upper end surface 2 by a pin 19. It is rotatably mounted on the bottom surface. A spring receiving rod 20 that is integral with the upper end surface 2 passes through the supporting arm 7 with a margin, and a spring 21 held by the spring receiving rod 20 is pressed against the lower surface of the supporting arm 7, and the valve body 6 is pressed against the lower surface of the supporting arm 7.
Thus, the discharge port 3 is always closed.

Further, the support arm 7 is provided with inclined surfaces 8 on both sides. This inclined surface 8 corresponds to the pin 19
It has a slope that gradually increases from the direction toward the valve body 6 (that is, approaches the upper end surface 2).

On the other hand, the above-mentioned hinge 5 is attached to the peripheral wall 9 of the lid body 1.
A hole 10 is provided below, and the base of an operating rod 11 is slidably and loosely fitted into this hole 10. The operating rod 11 is divided into two parts from the base, and
The upper surface and both side surfaces of the crotch portion are guided by a downward U-shaped guide member 22 provided integrally with the lower surface of the upper end surface 2. Further, the tips of the two fork portions are in contact with the inclined surface 8, respectively.

Further, a sealing member 15 is fitted to the base of the operating rod 11, and the operating rod 11 is in the most retracted state (the first position).
In the state shown in the figure), the hole 10 is closed.

An operation button 12 is attached to the end of the operation rod 11 protruding from the peripheral wall 9, and the operation button 1
2 is integrally provided with a rack rod 13.

The rack rod 13 is slidably fitted into a guide groove 23 provided in the radial direction on the upper surface of the upper end surface 2 through below the hinge 5 of the opening/closing lid 4. A rack 24 is partially provided on the upper surface of the rack rod 13, and a pinion 14 that meshes with the rack 24 is provided on the hinge 5 of the opening/closing lid 4. The pinion 14 in this case does not need to have teeth all around it;
It is partially provided to the extent that the opening/closing lid 4 can be rotated approximately half a turn.

The lid opening device according to the embodiment of this invention has the above-mentioned structure, and its operation will be explained next.

In normal conditions, as shown in FIGS. 1 and 2, when the operation button 12 is not operated, the elasticity of the spring 21 pushes up the support arm 7 and the valve body 6 integrated therewith, The outlet 3 is closed, and the opening/closing lid 4 covers the outlet 3 and the drinking spout 17. Further, the sealing member 15 seals the hole 10 to prevent liquid leakage.

Next, press operation button 1 with the fingertip of the hand holding the container.
2, the operating rod 11 will open as shown in FIG.
As it moves forward, its tip rides on the inclined surface 8, tilts the supporting arm 7 downward against the elasticity of the spring 21, separates it from the valve body 6 integral with it, and the discharge port 3, and opens it.

Simultaneously with the above action, the rack lever 13 also moves forward, causing the pinion 14 meshed with the rack 24 to partially rotate, thereby opening the opening/closing lid 4 integrated therewith.

Thereafter, when the container is tilted, the beverage flows out from the outlet 3. In this case, since the sealing member 15 is separated from the hole 10, air can flow into the container and negative pressure can be avoided.

When you finish drinking and release your fingertips from the operation button 12,
The support arm 7 is pushed back by the elasticity of the spring 20, and at the same time, the operating rod 11 is also pushed back by the inclined surface 8 of the support arm 7. As a result, the valve body 6 returns to its original state and closes the outlet 3, and the opening/closing lid 4 covers the outlet 3 and the drinking spout 17 as before.

〔effect〕

Since the lid opening device of this invention is as described above, the opening/closing lid and the valve body can be opened and closed simply by operating the operation button with a fingertip.

Therefore, it is convenient not only to be able to drink while holding the container with one hand, but also to open and close the lid with one hand.
