The present invention has been made to solve such a problem, and an object of the present invention is to provide a lid having a simple structure integrally provided with a backflow prevention structure. A drinking container spout of the present invention is a drinking container spout having a top surface and side surfaces, and covers a region above the upper surface near the first side surface and the first side surface. A cover portion, a return portion formed integrally with the inner surface in the inner space of the cover portion and forming an outlet for the beverage between the inner surface of the cover portion at the top thereof; And a barrier formed in a region near the second side opposite to the region.

Description

  The present invention relates to a drinking mouth of a beverage container having a shape in which germs in the mouth do not flow back into the bottle even if the bottle is attached to the neck of a bottle or the like to drink directly with the mouth.

When drinking directly from a beverage container such as a bottle, the beverage that touched the mouth flows back into the bottle, so that germs are mixed into the beverage remaining inside the bottle, and the germs grow over time. If you drink the drink again, it may harm your health.
In order to solve such a problem, for example, a drinking mouth having a structure for preventing a backflow using a check valve as shown in Patent Document 1 is known.

Japanese Patent No. 6268377

  However, the structure of the drinking mouth provided with the check valve as described above has a large number of parts and a complicated structure. The present invention has been made to solve such a problem, and an object thereof is to provide a drinking mouth having a simple structure integrally including a backflow prevention structure.

  The drinking mouth of the beverage container of the present invention is a drinking mouth of a beverage container having an upper surface and a side surface, and covers the upper side and the first side surface side of the upper surface near the first side surface; The return portion that is integrally formed with the inner surface of the inner space of the cover portion and that forms a beverage outflow hole between the inner surface of the cover portion and the inner surface of the cover portion is opposite to the region near the first side surface of the upper surface. And a barrier portion formed in a region near the second side surface on the side.

By using the drinking mouth of the present invention, the decay of the liquid remaining in the bottle is suppressed, and it can be safely drunk even if divided into several times thereafter.
When wearing a drinking mouth of the present invention on the neck of a bottle or the like, while tilting the bottle or pushing the bottle, when drinking a drink with a mouth directly so that the lower lip hits the barrier part of the drinking mouth of the present invention, Since the beverage enters the mouth so as to drop from the upper beverage outlet hole, the beverage remaining in the bottle does not come into contact with the beverage in the mouth or the mouth.
In addition, when returning the tilt of the bottle when drinking is finished, the beverage outside the return part inside the cover part falls into the mouth, and the beverage inside the return part returns directly into the bottle. The reverse flow does not occur. Therefore, the germs in the mouth are not mixed in the bottle, and the germs can be prevented from breeding with time in the bottle.
Furthermore, even if the upper lip contacts the outside of the cover part, the outflow hole of the beverage is covered with the cover, so the outflow hole does not directly contact the lip or the mouth.

It is a perspective view of one embodiment of the present invention. It is the figure which looked at the lid | cover of one Embodiment of this invention from the side. It is sectional drawing of the lid | cover of one Embodiment of this invention.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a perspective view of a drinking mouth according to an embodiment of the present invention, and FIG. 2 is a side view of the drinking mouth. The drinking mouth is integrally formed with the inner surface of the dome-shaped cover portion 2 and the inner space of the cover portion 2 so as to cover the upper side of the upper surface 7 near the first side surface and the first side surface side. In the top part, the return part (inclined wall part in which the cross section is convex arc shape) 4 which forms the outflow hole 3 of drink between the inner surface of the cover part 2, the 1st side of the upper surface 7 on the opposite side to the area | region near the 1st side surface. It is comprised by the barrier part 5 (arc-shaped inclined wall formed in the side surface side) 5 formed in the area | region near 2 side surfaces.

  FIG. 3 is a cross-sectional view of the drinking mouth shown in FIGS. 1 and 2. The drinking mouth of an embodiment of the present invention has a threaded portion 6 inside the main body, and is used by attaching the drinking mouth of the present invention to the neck of a container such as a plastic bottle.

  When drinking while tilting the bottle, it is used with the cover portion 2 facing upward as shown in FIG. That is, the upper lip is applied to the upper side of the cover part 2 and the lower lip is applied to the lower side of the barrier part 5 for use. The beverage inside the bottle flows out from the opening 1 through the outflow hole 4 and into the oral cavity.

.
When the beverage flows out, the cover 2 prevents the upper lip from directly touching the opening 1 and the outflow hole 4. Further, since the lower lip hits the barrier portion 5, a person holds the cover portion 2 and prevents the lower lip and tongue from touching the return portion 3 and the cover portion 2.

  When the barrier portion 5 hits the lower lip, an appropriate space is formed in the outflow hole 4 through which the beverage flows out and the oral cavity, and the beverage in the bottle and the beverage in the oral cavity can be prevented from being connected.

  Each time the beverage in the bottle is taken, the inclination of the bottle returns to the vertical direction. At this time, the beverage on the bottle side returns to the bottle, and the beverage on the oral cavity flows into the oral cavity. This prevents the beverage from flowing back from the mouth into the bottle.

  The drinking mouth of the present invention has a simple structure and can be manufactured and cleaned relatively easily. Among various backflow prevention mechanisms, there is a possibility that it can be provided at low cost.

  The usage of the drinking mouth of the present invention is generally the same as the method of drinking a beverage from a bottle. It is designed to be easy for elderly people and small children to use because it can be drunk in an appropriate amount by tilting the bottle or pressing the bottle body lightly. Needless to say, the shape of the threaded portion 6 can be attached to various types of bottles and the like by manufacturing according to the shape of the bottle neck.
