JPH0710610Y2 - Lid with a mouthpiece to prevent spillage - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a lid with a mouthpiece for preventing spillage applied to a beverage container.

[Conventional technology]

Conventionally, there are two types of beverage containers, one with a lid removed for drinking and the other with a lid attached. Among them, some of the containers which are intended to be drunk with the lid attached have a straw insertion port or a straw attached to the lid.

If you remove the lid and drink from the container, it tends to spill, especially when riding in a vehicle, but if you drink with a straw with the lid on, there is no risk of spilling, so recently a lid with a straw is It tends to be used more often.

[Problems to be solved by the invention] However, when drinking a drink with a straw, it is necessary to pay attention to the fact that the straw and the mouth are attached. When the vehicle is vibrating violently, for example, when you are going to take a drink on a fishing boat in the rough surf, you need to be standing up and your hands naturally move to the left and right to maintain the center of gravity. Since it shakes, if the container does not have a lid, the contents will overflow, of course.
When drinking with a straw with a lid, it was extremely difficult to hold the tip of the swinging straw with the mouth because the tip of the straw is far from the hand.

In addition, children often have problems with the tip of the straw sticking their eyes and mouth.

In view of the above situation, the present invention has a lid provided with a drinking mouth, and since it is closed at all times, the beverage does not overflow from the container even when swinging, The purpose is to be able to open it only when you do.

[Means for Solving the Problems]

To achieve the above object, the structure of the present invention is such that an opening is formed at one end of the top wall of a lid made of an elastic material so that an opening / closing hinge is provided on the center side of the lid, and the opening / closing hinge is provided together with a drinking mouth. Forming a sealing piece that opens the drinking mouth by pushing down through the part and closes the drinking mouth by releasing the pushing down, and at the sealing piece, the top wall of the lid is raised so that the drinking mouth is opened. When the container is attached and the container is tilted, the mouth end hits and the mouth end is pushed to resist the elasticity of the opening and closing hinge part, and this sealing piece is pushed down to open the drinking mouth. The main point is a lid with a mouthpiece for prevention.

In addition, a ridge-shaped back-leakage prevention guide formed of the upper wall of the lid may be formed on both sides of the drinking opening.

[Action]

When using the lid with a mouth configured as described above,
It may be placed over a cup or bowl, or it may be integrated into a beverage can. That is, on the ceiling of the drinking can,
The present invention can be implemented.

The material of the lid may be paper, metal, plastic, or the like, but the elastic hinge portion is required to have appropriate elasticity capable of achieving the object of the present invention.

In any case, with this lid, when you drink from a container, keep your mouth open (usually your upper lip)
When the mouth tip abutting portion formed in a protruding shape is pushed down, the sealing piece is pushed together and the drinking mouth is opened, so that the beverage can be put into the mouth while tilting the container with the drinking mouth opened.

Further, when the mouth is removed from the mouth when the drink is finished, the sealing piece closes due to the elasticity of the hinge portion only by that, so that the mouth is opened only for a short time when the drink is taken.

Further, the back leakage is prevented by the guides provided on both sides of the drinking mouth.

〔Example〕

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 show one embodiment, and the lid P with a drinking mouth for preventing spillage is attached to a cup C, and has a shallow cap shape so that it fits into the mouth of the cup C. It is made of plastic and has a cup C on the outer wall 1.
An inward projection 3 is formed so as to hang on the mouth circumference projecting edge portion 2, and the upper surface wall 4 is provided with a drinking mouth 5 at one end portion thereof.

The drinking mouth 5 is formed with a sealing piece 10 by making a notch 6 in the upper surface wall 4, and the notch 6 is formed by an arc line 6a that bends along the outer peripheral edge and side lines 6b and 6b. The opening / closing hinge portion 7 of the sealing piece 10 is provided on the center side. And both lines
A wide space is formed in the outer peripheral direction between 6b and 6b, and the drinking mouth 5 is widened in that direction.

In addition, the notch 6 may be a method that can be separated by engraving before use, or that is cut from the beginning,
either will do.

A protrusion 11 is formed on the upper surface of the sealing piece 10 by the protrusion of the wall. As will be described later, this protrusion 11 is a portion where the upper lip just comes into contact when the cup C is tilted to drink a drink.
The upper wall 4 is also provided with guides 12 and 12 on both sides of the drinking opening 5 for preventing back leakage through the protrusion of the wall.
Are formed in parallel with both side lines 6b, 6b of the cut 6.

If the cup P is covered with the lid P (Fig. 2) and the notch 6 is engraved, it is cut off, and when drinking the drink inside, when the mouth is attached to the drinking mouth 5, the upper lip just touches the protrusion 11. Lever projection
11 is pushed down, whereby the sealing piece 10 is opened (FIG. 3), and when the cup C is tilted toward the mouth, the drink is injected into the mouth from the drinking mouth 5. At this time, Even if it leaks to the side, it will be guided to your mouth by the guides 12 and 12, so you can drink safely without spilling. Also guide 12,
12 also plays the role of so-called back leakage prevention.

Further, since the hinge portion 7 has the elasticity of plastic, when the lip is removed from the protrusion 11, the sealing piece 10 is restored by the elasticity to seal the drinking mouth 5.

The elasticity of the hinge portion 7 allows the protrusion 11 to be pushed down to the extent that a suitable amount of drink can be drunk by lightly pressing the upper lip, and when the pressing is released, the original position, that is, the drinking mouth 5 is sealed. It is only restored to the position. This is the type of drink,
It is appropriately determined depending on the size of the cup, the use, etc.

[Other Examples]

5 to 8 show another embodiment, in which case
The upper wall 4 of the lid P is provided with a recess 15 into which it sinks, so that the periphery thereof is used as a guide 12 for preventing back leakage, and the drinking port 5, the sealing piece 10, and the hinge are provided in the recess 15. The portion 7 is formed by the notch 6, and the protrusion 11 of the sealing piece 10 is formed at a height protruding from the recess 15.

Reference numeral 16 is a recess provided to alleviate the fact that the tip of the nose hits the upper surface wall 4 of the lid P when the cup is tilted and the tilt of the cup is limited. Recess
It is also a symmetrical recess that balances with 15 in design.

The drinking mouth 5 may be formed to have a narrow width in the outer peripheral direction contrary to the case shown in the drawing, and may have an appropriate curved shape or a specific geometrical or pictorial shape.

[Effect of device]

As described above, according to the lid of the present invention, since the drinking port is directly provided on the lid, even if the lid is shaken while riding on a vehicle, the container with the lid is held by hand. Of course, the mouth of the lid can be easily attached to the mouth,
The mouth opens only when you push the protrusion with your upper lip, so even if the vehicle rocks violently, you can safely drink without the risk of zeroing the drink. Since it is naturally sealed, it does not drip the drink even at that time, it is hygienic without dust and has many uses,
It has an excellent effect that it can be used in a wide range regardless of adult or child. Also, by providing guides on both sides of the drinking mouth, so-called back leakage can be prevented.

In particular, the lid of the present invention is most suitable as a lid for drinking carbonated and effervescent drinking water in which gas emission becomes intense due to rocking.
