Embodiments of the present invention will be described below with reference to the drawings.

[0007] The cap 1 of the present invention comprises a main body 2 and a lid 3.
And a cover opening member 4.

The main body 2 is made of a synthetic resin. A top plate 8 extends from an upper end edge of a fitting cylinder 7 fitted to the outer periphery of the mouth and neck 6 of the container body 5, and a spout 9 is formed in the top plate 8. ing. The spout 9 can take various forms as long as a rod plug to be described later can be tightly fitted. In the illustrated example, the spout 9 has a short cylindrical shape with its base end opened at an eccentric position at the front part of the top plate 8 and rising upward. The taper portion 10 is provided on the upper part of the inner surface so that the rod plug can be more easily fitted. However, the configuration of the spout is not limited to this, and may be a spout simply perforated in the top plate 8, and the perforated position is not limited to the eccentric position but may be provided at the center position.

In the illustrated example, an engaging ridge 12 projecting from the inner periphery of the fitting cylinder 7 is engaged with a lower surface of the locking ridge 11 projecting from the outer periphery of the mouth and neck portion 6 to prevent it from slipping upward. I'm trying.
In addition, a seal cylinder 13 closely fitted to the inner surface of the mouth and neck 6 is vertically provided from the back surface of the top plate 8 to prevent leakage of liquid from this portion. Further, an annular concave portion 14 for fitting the cover 3 is formed in the peripheral portion of the upper surface of the top plate 8.

A projection 15 is provided at a predetermined position on the top surface of the top plate 8. The specific shape of the projection 15 can be variously adopted as long as the lower end thereof can slide up along with the rotation of the leg, and in the illustrated example, a plane having a triangular shape in a side view having an inclined surface S1 descending rearward. The projection 15 has a horizontally-long rectangular shape when viewed. The projection 15 may have a curved surface on which the lower end of the leg can slide up.

The lid 3 is also made of a synthetic resin. The lid 3 is rotatably connected to the rear of the main body 2.
It is possible to employ a bar-shaped one configured such that a rod plug 17 vertically provided from the back surface of the top wall 16 is fitted closely to the spout 9. In the illustrated example, the top wall 16 is extended from the upper edge of the peripheral wall 18 with the lower edge fitted to the annular concave portion 14, and the lower rear end of the peripheral wall 18 is rotatable via the thin hinge 19 at the upper end of the main body rear. Also, on both sides of the thin hinge 19, arcuate elastic plates 20 connecting the upper part of the fitting cylinder 7 of the main body 2 and the lower part of the lid peripheral wall 18 are integrally provided, respectively, and the lid 3 is elastically inverted. It is configured to be possible. The rod stopper 17 may be of a form that is tightly and removably fitted to the spout 9 and may be formed in a hollow cylindrical shape as shown in the illustrated example or may be a solid rod shape. Since the shape can be delicately deformed, it is preferable to obtain more liquid tightness. An arc-shaped wall 21 having a front opening is vertically provided on the back surface of the top wall 16 around the rod stopper 17.

A window hole 22 is formed in the top wall 16 of the lid 3, and the window hole 22 is formed.
A cylindrical portion 23 is provided, which is rotatably connected to the upper end edge of the inner side and rotatably swings inward and outward, to the edge portion of the top wall 16 at the inner side portion 22. Although the shape of the window hole 22 and the cylindrical portion 23 is not particularly limited,
The window hole 22 is formed large enough to allow the inside and outside of the 23 to swing. In the illustrated example, a horizontally long rectangular window hole 22 is provided in front of the rod stopper 17.
A rectangular cylindrical portion 23 having upper and lower openings with upper and lower ends rotatably connected via a hinge portion 24 is provided at the edge of the top wall 16 at the rear edge portion of the window hole 22. . The cylindrical portion 23 in the illustrated example is configured such that the width of the hinge portion 24 for swinging can be formed to be somewhat long so that stable swinging in a certain direction is possible. If the thickness or material or the thickness and the material of the hinge portion 24 are selected to have an elastic restoring force, the push-up plate 27 which has been pushed up is selected.
Automatically returns to its original state, which is preferable. An engagement ridge 25 is provided at the lower end of the inner periphery of the cylindrical portion 23 so as to protrude therearound. Note that the window hole 22 can be formed in the top wall 16 except for the bar plug 17 hanging portion, and the position of the projection 15 can be determined accordingly.

The lid member 4 is also made of a synthetic resin, and the leg portion 26 penetrating through the cylindrical portion 23 is fitted to the lid top wall.
The push-up plate 27 placed on the upper surface 16 is vertically provided from the lower surface. Also, by pushing up the outer edge protruding outward from the lid top wall 16, the lower end of the leg 26 slides up on the protrusion 15 protruding from the main body top plate 8, and the lid is lifted. It is configured to push up and open the lid.

As shown in FIGS. 3 to 5, the lid member 4 of this embodiment has a leg 26 having a rectangular cross section and a lower surface inclined S2 from the center of the rear portion of a rectangular push-up plate 27. Has been established. leg
An annular concave groove into which the above-mentioned engaging ridge portion 25 is fitted is formed on the lower part of the outer periphery of 26.
There are 28 around. Further, an arc-shaped frame-shaped projection 29 to be engaged with the peripheral edge portion of the lid top wall 16 is protruded from the outer peripheral edge portion of the lower surface of the push-up plate 27.

As shown in FIG. 1, the legs 26 of the lid member 4 are fitted through the cylindrical portion 23 so as to fit therewith.
The inclined surface S2, which is the lower surface of 26, is placed in contact with the inclined surface S1, which is the upper surface of the projection 15 of the main body 2, and the front edge of the upper surface of the top wall 16 is projected forward of the top wall 16. , A push-up plate 27 is placed. At this time, the frame-shaped projection 29 is engaged with the front corner portion of the lid. As shown in the enlarged view of FIG. 6, the engagement ridge 25 of the cylindrical portion 23 is fitted in the annular groove 28 of the leg 26 to prevent the cylindrical portion 23 from coming off.

An example of using the cap 1 configured as described above will be described. First, when the projecting portion of the push-up plate 27 is pushed upward from the state of FIG.
, The cylindrical portion 23 rotates so as to shift its lower end forward, and at the same time, the leg portion 26 rotates. At this time, the leading edge of the inclined surface S2 of the leg 26 slides up on the inclined surface S1 of the projection 15, and the lid 3
Push up the front part to remove the plug 17 from the spout 9 (Fig. 7).
(A)). Although the rod stopper 17 is not completely removed in the same figure, it is in a state where it is removed with a small force as compared with the initial close fitting state. Next, when the push-up plate 27 is still pushed up,
The rod stopper 17 is completely removed from the spout, and the lid 3 is inverted by the elastic inversion mechanism to keep the lid open (FIG. 6B).
