Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cap having an outflow hole.

[0002]

2. Description of the Related Art A cap having an outflow hole formed by a cap body having an outflow hole and an auxiliary cap having the outflow hole openably and closably attached to the cap body via a so-called three-point hinge is widely used. ing.

[0003]

In the above conventional cap, since the auxiliary cap is elastically inverted, opening and closing of the outflow hole can be ensured. However, the auxiliary cap is formed almost in the same manner as a normal cap. Therefore, there are disadvantages that a large amount of molding material is required as compared with the general caps, and that the cost is increased due to the relatively complicated structure.

In the present invention, the central portion of the top wall of the cap is formed as an elastic reversing portion with a lever, and when the reversing portion is raised by operation of the lever, an outflow hole provided in the reversing portion is opened. Are provided so as to be closed, so that the opening and closing of the outflow hole is ensured with a simple configuration.

Means for Solving the Problems The outer peripheral portion of the top wall hanging down the peripheral wall 2 for fitting the mouth and neck of the container body is a thick flange portion 3, and the central portion of the top wall surrounded by the flange portion is located inside the flange portion. Between the front and rear portions of the peripheral edge, the refracting plate 7 laid in a U-shape via the first and second hinges 5 and 6, and approximately right and left edges of the inner periphery of the flange-shaped portion from both left and right sides of the refracting plate. The elastic thin plates 8, 8 descending at the same inclination angle are closed, and the refraction plate is connected to each end of the short plate 9 and the long plate 10 via the third hinge 11. 4, and a lever 13 for extending the protrusion 4 elastically downward from the tip of the long plate 10 longer than the short plate 9 is provided. At times, the outflow hole 12 protrudes at an angle at which the side surface of the lever 13 can be sealed.

[0006]

In the state shown in FIGS. 1 and 3, an outflow hole 12 formed in the short plate 9 is opened. When the distal end of the lever 13 is pushed downward to the right in FIG. 1 from the illustrated state, the refracting plate 7 and the elastic thin plates 8 are elastically inverted as shown in FIG.
Seal. In this state, when the lever tip is pushed upward to the left in the figure, the outflow hole 12 is opened again as shown in FIG.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A cap 1 is integrally formed of a synthetic resin material having excellent bending and elongation resistance. As the flange portion 3, a central portion of the top wall surrounded by the flange portion is a raised portion 4 with a lever that can be elastically inverted in the vertical direction. The protruding portion has a bent shape between the front and rear portions of the inner periphery of the flange-shaped portion via first and second hinges 5 and 6 in the shape of an ellipse. The refraction plate is formed by connecting a short plate 9 and a long plate 10 with a third hinge 11 interposed therebetween. An outlet hole 12 is formed in the middle of the short plate 9 and a sealing ridge is formed in the outer peripheral edge thereof.
The short plate 9 is a relatively thick rigid plate, and the long plate 10 is formed to be elastically deformable. The lever 13 protrudes from the short plate side end of the long plate 10. The lever is provided such that the raised portion 4 is elastically inverted downward as shown in FIG. 2 by pressing the tip of the lever downward and downward from the state of FIG. Is projected from the end of the long plate 10 at an angle for sealing. The elastic thin plates 8, 8 and the above-mentioned short plate 9 are inclined at substantially the same angle, so that a ridge line is formed in the elastic thin plate between the long plate side portion and the short plate side portion. As a result, the ridge lines have a rib function and make it difficult to elastically deform for elastic reversal. Therefore, as shown in FIG. 14,
14 The inclination angle of the elastic thin plates 8, 8 in the portion is adjusted so that the inner peripheral edge becomes an arc shape to prevent the generation of the ridge line. Reference numeral 2a denotes a seal cylinder fitted to the inner surface of the mouth and neck of the container body, which is hung down from the inner peripheral portion of the flange-shaped portion 3 described above.

According to the present invention, the outer peripheral portion of the top wall is a thick flange portion 3 and the center of the top wall surrounded by the flange portion is located between the front and rear portions of the inner peripheral edge of the flange portion. A refracting plate 7 laid in a U-shape via the first and second flanges 5 and 6 and elasticity descending from both left and right sides of the refracting plate to both right and left edges of the inner periphery of the flange portion at substantially the same inclination angle. Thin plate 8,
8, the refraction plate is connected to the short plate 9 and the long plate 10 at the respective ends thereof through the third hinge 11 to form the elastically reversible raised portion 4. By using the lever, the protrusion 4 can be easily elastically inverted, and the short plate 9 has an outlet hole.

The operation plate is also used as an operation plate for reversing the elasticity, and also serves as a lid plate for opening and closing the outflow holes, so that the structure of the cap can be simplified, and the length of the lever 13 is made larger than the length of the short plate 9. When the raised portion 4 is elastically inverted downward, the lever
As shown in FIG. 2, the distal end of the projection 13 protrudes above the flange 3 so that the elastic inversion operation in the upward direction of the raised portion, which is performed by using the distal end of the lever, becomes easy.

(57) [Scope of request for utility model registration] An outer peripheral portion of a top wall hanging down from a peripheral wall for fitting a mouth and neck portion of a container body is formed as a thick flange portion, and a central portion of the top wall surrounded by the flange portion is provided on both front and rear sides of an inner peripheral edge of the flange portion. Between the parts, the first and second hinges 5, 6 are provided with a refracting plate 7 laid in a U-shape and the left and right sides of the refracting plate to the left and right edges of the inner periphery of the flange-like portion at almost the same inclination angle. Closed by the descending elastic thin plates 8, 8, the refraction plate is connected to each end of the short plate 9 and the long plate 10 via the third hinge 11 to form the elastically invertible raised portion 4. An outflow hole 12 is formed in the short plate 9 and a lever 13 that is longer than the short plate 9 from the end of the long plate 10 and elastically inverts the raised portion 4 downward is used.
A cap with an outflow hole, wherein the outflow hole 12 protrudes at an angle at which the side surface of the lever 13 can be sealed when the elasticity is lowered downward.
