DETAILED DESCRIPTION OF THE INVENTION A beverage container according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a beverage container 30 according to an embodiment of the present invention. In this beverage container 30, the opening of the container body 32 is attached to the opening of the container body 32 by attaching the dome-shaped lid 34 formed with the ceiling portion 34a inclined in an oblique direction. It is blocked. Further, this prevents liquid leakage when the container body 32 is turned upside down. Handles 35, 35 are provided on both sides of the container body 32, and an infant can grab the handle 35 to allow the infant to drink. The handle 35 may be directly provided on the container body, but may be detachably formed in consideration of cleaning performance and operability when the lid 4 is attached to the container body 32. Further, a substantially hemispherical cap member 36 made of a translucent material is rotatably installed on the dome-shaped lid 34 at a position opposite to the ceiling surface 34a. When the cap member 36 is rotated in the direction of arrow A, the mouthpiece member 40, which is a communication part that connects the inside and the outside of the container body 32, is covered. The cap member 36 covers the obliquely inclined ceiling portion 34a to maintain the hygiene of the mouthpiece member 40. However, since the cap member 36 is made of a transparent material, it is not blocked. You can see the inside even if you do.

Therefore, such a cap member 36
Protects the mouthpiece member 40 when not in use.
Can be kept in a storage state, and if this is removed, the infant can freely drink when he wants to drink.
The detailed structure of the mouthpiece member 40 will be described below. As shown in FIG. 2, the mouthpiece member 40 includes an axially extending pacifier portion 42, a stopper portion 44 provided on the base side of the pacifier portion 42, and a stopper portion 44.
And a straw insertion portion 46 for attaching and detaching a straw (not shown) extended below the straw.
The lower surface of 6 is provided with a disk 48 for facilitating the attachment / detachment operation of the mouthpiece member 40. A central through hole 50 is formed from the pacifier portion 42 to the disk 48, and the solution in the container can be sucked through the central through hole 50.

The mouthpiece member 40 as described above is formed by forming a core material made of a hard resin and laminating a surface material made of a soft resin around the core material. Therefore, the pacifier part 42 that enters the infant's mouth
From the stopper member 44 to the stopper member 44, the stopper member 44 is made of a flexible resin, which makes the lid 34 liquid-tight as well as less discomfort when gripped. Also, the overall strength is
It is maintained by the core material inside. Pacifier part 4
A retaining flange portion 52 is formed on the outer periphery of the base end side of 2. The retaining flange portion 52 is formed in an elliptical shape as described below.

That is, as shown in FIG. 3, the flange portion 52 has a major axis R arranged in the vertical direction and a minor axis r arranged in the lateral direction. At this time, the hole 49 of the lid 34
The diameter of the minor axis r of the flange portion 52 is slightly larger than the true circular hole diameter. The elliptical flange portion 52 that is long in the vertical direction is formed in the aspect shown in FIG. 3 with respect to the flat pacifier portion 42 that is long in the horizontal direction.

Therefore, an infant or the like can use this pacifier part 4
When 2 is put in the mouth and held, the short diameter r side is arranged in the left-right direction and the long diameter R side is arranged in the vertical direction. Further, the mouthpiece member 40 thus formed is detachably inserted into the dome-shaped lid 34, as shown in FIG. That is, the dome-shaped lid 34 has the ceiling portion 34.

The mouthpiece member 40, as shown in FIG.
The tip of the pacifier portion 42 is inserted into the hole 49 of the dome-shaped lid 34 from the back side of the dome-shaped lid 34. At this time, the retaining flange portion 52 reaches the hole portion 49 following the shaft portion of the pacifier portion 42. However, since the retaining flange portion 52 is caught in the hole portion 49, the retaining flange portion 52 cannot easily come out of the hole portion 49 as it is. In particular, the vertical edges are hard to come off. Here, if the operator pushes the retaining flange portion 52 with a little force while slightly swinging the mouthpiece member 40 back and forth, the flexible retaining flange portion 52 is allowed to pass through the hole portion 49. be able to. At this time, since the retaining flange portion 52 has a large diameter in only one portion and the other portion having a diameter slightly larger than the diameter of the hole portion 49,
It does not require so much force and the hole 49
Can be passed through. Moreover, the mouthpiece member 40 fitted in the hole 49 of the lid 34 in this manner is
Since the longitudinal direction is arranged to the left and right with respect to the mouth and the latitudinal direction is arranged above and below, respectively, not only the mouthpiece member 40 is difficult to slip out from the hole 49 but also the lip is not easily moved by the normal movement of the mouth of the infant. For infants with a weak closing force, the shape is easy to hold and suck.

It should be noted that if the retaining flange 52 is elliptical as in this embodiment, it becomes difficult for the flange 52 to be removed. Therefore, as shown in FIG. 2, the retaining flange 52 and the stopper are provided. The distance S from the bottom surface of the inner tubular portion 51 shown in FIG.
It is longer than the distance T to. As described above, since the flange portion 52 has the elliptical shape, the mouthpiece member 40 does not fall out of the hole portion 49. Moreover, when the mouthpiece member 40 is fitted, it can be fitted with a slight amount of play, so that the operator can recognize that it is fitted and prevent it from being set in an insufficient state. I can do things.

At this time, with respect to the distance T which is the thickness at the inner circumference of the hole 49, the flange portion 52 to the stopper portion 44.
