[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
The cap according to the present invention includes a cap body 1 and a lid 21.
[0010]
The cap body 1 has an elliptical shape that is long in the left-right direction. As shown in FIG. 1, an inner cylinder 4 is fitted from a top plate 3 on which a nozzle 2 stands up to an outer surface of a mouth and neck of a container body as shown in FIG. An outer cylinder 5 surrounding the inner cylinder 4 is suspended. Reference numeral 8 denotes a seal cylinder fitted to the inner surface of the mouth and neck. As shown in FIG. 1, the upper end of the outer cylinder forms a small outer diameter portion 7 via an upward stepped portion 6. The inner cylinder 4 has a perfect circle for fitting the mouth and neck, and the outer cylinder 5 has an elliptical shape. The nozzle 2 has a hemispherical shape, and has a pouring hole 2a formed near the upper front surface thereof.
[0011]
As shown in FIG. 2, the outer cylinder rear wall portion below the upwardly directed step portion 6 is formed on the elastic operation plate 11 by being cut apart by forming a separation line 12 except for the lower side. The separation line 12 is formed by drilling the inner edge (small outer edge lower end edge) of the rear portion of the upward step 6 and the portion that crosses the upward step 6 from the left and right ends of the inner edge to the lower portion of the cap body outer cylinder 5. I have. A first projection 13 having a flat upper surface protrudes rearward from the rear end of the elastic operation plate 11 as shown in FIG. 3, and an elasticity formed at the rear upper surface of the upward step 6. The upper end surface of the operation plate 11 and the upper surface of the first protrusion 13 are continuously provided at the same height as a sliding surface of a wedge-shaped portion described later. On the outer surface of the elastic operation plate 11 below the first protrusion 13, a finger contact protrusion 14 is provided vertically.
[0012]
The rear portion of the small outer diameter portion 7 is formed as a wedge-shaped portion 16 by being formed on an inclined wall which descends obliquely downward and outward. The lower end surface of the wedge-shaped portion is a horizontal plane having the same height as the upper end surface of the elastic operation plate 11, and when the lid 21 is fitted to the cap body 1, the front edge of the upper end surface of the elastic operation plate 11 and the tip of the wedge-shaped portion 16 are formed. Are provided so as to face each other.
[0013]
Further, the upper portion of the front wall of the outer cylinder 5 of the cap main body is cut off by forming a separation line 19 to form an elastic locking plate 18, and the outer surface of the small outer diameter portion of the elastic locking plate is provided with a first engaging means. 20 is provided with an engagement projection.
[0014]
The lid 21 is connected via a hinge 31 at an upper rear portion of the cap body 1, and is formed so as to be fitted to the upper surface of the cap body 1 by rotating about the hinge. At the time of the fitting, the lid 21 fits the lower part of the peripheral wall 24 hanging down from the top wall 23 to the outer surface of the small outer diameter part 7 of the cap body 1 and the lower end surface of the peripheral wall 24 to the upper surface of the upward stepped part 6. It can be placed. The lid 21 has a flat elliptical shape like the cap body 1. In addition, a plug as the pouring hole closing portion 25 is hung down from the back surface of the lid top wall 23, and the plug is liquid-tightly fitted to the outer surface of the nozzle 2. In the front wall portion of the lid peripheral wall 24, an engagement concave portion that engages with the engagement convex portion on the cap body side is formed as a second engagement means 26.
[0015]
Further, the rear wall portion 28 of the lid peripheral wall 24 is formed as an elastic wall portion that can swing inward around the rear end portion of the lid top wall 23. A second projection 29 having a flat lower surface is attached to the rear end of the elastic wall portion, and the rear end of the second projection and the rear end of the first projection 13 of the cap body are connected to each other. The wedge-shaped portion insertion margin L is formed between the hinge and the front corner portion 34 at the lower end of the rear wall portion 28 of the lid peripheral wall. Further, a pair of meandering elastic strips 32, 32 are attached to the rear surfaces of the outer cylinder 5 rear wall portion and the lid peripheral wall 24 rear wall portion on the left and right sides of the first and second protrusions 13, 29, respectively. These elastic strips and the hinges 31 constitute an elastic inversion type hinge mechanism 30. The front corner 34 at the lower end of the rear wall 28 of the peripheral wall of the lid is chamfered as shown in FIG.
[0016]
In the above configuration, when the front surface of the elastic locking plate 18 and the rear surface of the elastic operating plate 11 are pushed inward from the closed state shown in FIG. 3, the engagement of the first and second engagement means 20, 26 is released. At the same time, the elastic operating plate 11 and the rear wall 28 of the lid peripheral wall are bent inward, and the front corner 34 at the lower end of the elastic operating plate 11 rides on the upper surface of the wedge-shaped portion 16 as shown in FIG. At the center, the lid 21 is pushed up to at least a thought point (a point where the urging force in the opening direction and the urging force in the closing direction of the hinge mechanism are balanced) of the lid, and is elastically inverted from the thought point position to the open position. .
[0017]
When the lid 21 is rotated in the closing direction from the open state, the first and second engagement means 20 and 26 are engaged and return to the state of FIG.
[0018]
In the illustrated example, as described above, the rear wall 28 of the lid peripheral wall is an elastic wall that swings inward, and only the elastic wall is inwardly pushed by the inward pushing of the elastic operation plate 11. Although it is configured to be displaced, for example, the entire lid 21 can be slid forward with respect to the cap body 1 by pushing the elastic operation plate 11 inward.
[0019]
【The invention's effect】
The present invention is configured as described above, and the invention of claim 1 has the following effects.
The wedge-shaped portion 16 is inserted between the upper end portion of the elastic operation plate 11 and the lower end portion of the rear wall portion 28 of the lid peripheral wall by pushing the elastic operation plate 11 inward. 21 can be easily and reliably opened.
Since the wedge-shaped portion 16 is formed at the rear edge of the cap main body top wall 23, it can be formed by only slightly changing the configuration of the existing cap. For example, since the number of parts does not increase, Can be simplified.
[0020]
According to the second aspect of the present invention, since the rear wall portion of the lid peripheral wall is an elastic wall portion that can swing inward, the lower end portion of the lid peripheral wall is moved to the upper end of the outer cylindrical portion of the cap body. The lid can be opened by the wedge action of the wedge-shaped portion 16 also for the cap of the type in which is fitted.
[0021]
According to the third aspect of the present invention, since the upper end of the outer cylinder 5 is formed in the small outer diameter portion 7 via the upward stepped portion 6, the lower end of the lid peripheral wall 24 is fitted to the outer surface of the small outer diameter portion. The position of the lower end portion is determined by the combination, and the front corner portion 34 of the rear wall portion 28 of the peripheral wall is also positioned, so that the front corner portion 34 is securely pushed by the wedge-shaped portion by pushing the elastic operation plate 11 inward. Pushing up and opening the lid 21 can be performed.
[0022]
According to the invention of claim 4, the engagement between the first and second engagement means 20, 26 provided on the front side of the cap is released by sandwiching the front and rear walls of the cap body outer cylinder 5 with fingers and pushing inward. At the same time, the lid 21 can be opened by pushing up the front corner 34 at the lower end of the rear wall 28 of the lid peripheral wall with the wedge-shaped portion 16, so that the usability is good.
