Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a cap with a nozzle.

[0002]

2. Description of the Related Art A rear part of an auxiliary cap is connected to a rear part of a cap body which erects a nozzle shortly from a center part of a top wall by a so-called three-point hinge, and the auxiliary cap is raised and lowered by elastic reversal by the hinge action. A cap that opens and closes the nozzle opening with a stopper hanging from a wall is widely used.

[0003]

[Problems to be solved by the invention]
Since the nozzle opening is opened and closed by the reversal of the auxiliary cap,
Although the opening and closing thereof can be easily and reliably performed, there is a disadvantage that the structure of the three-point hinge portion is troublesome and the cost is high.

According to the present invention, a nozzle that rises from a cap top wall via a cylindrical pedestal can be raised and lowered by elastic reversal of a part of the cylindrical pedestal forming wall. The above disadvantage is eliminated by providing the rear wall so as to be closed by the front surface.

[0005]

A central portion of the top wall 2 hanging down from the peripheral wall 3 for fitting the mouth and neck of the container body is opened, and a cylindrical pedestal 4 is formed from the periphery of the mouth and a top plate 5 of the pedestal. And triangular side walls surrounded by a line connecting the flat rear wall 4a of the cylindrical pedestal and the left and right upper and lower ends of the side wall and the front lower end of the left and right side walls. Part 4b,
4b is a rigid thick wall portion, and the remaining cylindrical base forming wall portion excluding these thick wall portions is an elastically deformable thin wall portion 4
c, respectively, and the upper end of the rear wall 4a and the top plate 5
The trailing edge is connected by a thin hinge 7, and the thin wall portion 4c is
When the top plate 5 is rotated about the thin hinge 7 by pressing the nozzle 6 forward, the nozzle 6 is elastically inverted when the nozzle 6 falls forward, so that the opening surface 6a at the lower end of the nozzle can be brought into close contact with the front surface of the rear wall 4a. The triangular side portions 4b, 4b were formed in a partial shape of a truncated cone, and in an arc shape that coincided with a curved curve of a lower edge of a thin wall portion continuous with the upper surface of the portion.

[0006]

In the state shown in FIG. 2, the lower end opening surface 6a of the nozzle 6 is closely closed to the front surface of the rear wall 4a of the cylindrical base 4. When the tip of the nozzle 6 is pulled up from this state, the top plate 5 of the cylindrical pedestal rotates around the thin hinge 7, whereby the thin wall portion 4c is elastically inverted, the nozzle 6 stands up, and the lower end opening surface 6a is raised. Open. When the nozzle is tilted forward from the standing state, the thin wall portion 4c is again elastically inverted, and the lower end opening surface of the nozzle is closed.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A cap 1 according to the present invention has a peripheral wall 3 for fitting a mouth, neck and neck of a container body hanging down from an outer periphery of a top wall 2. The top wall is open at the center, and a cylindrical base 4 is formed from the periphery of the mouth, and a top plate 5 of the base is provided.
And the nozzles 6 are respectively erected from the periphery thereof.

The cylindrical pedestal 4 connects the rear wall 4a formed in the shape of a rectangular flat plate with the upper and lower ends of the rear wall and the lower end of the front part of the left and right side walls protruding forward from the right and left ends of the rear wall. The triangular side wall portion surrounded by the three lines is a rigid thick wall portion, and the remaining cylindrical pedestal forming wall portion excluding these thick wall portions is a thin wall portion 4c that can be elastically deformed. . The upper end of the rear wall 4a and the rear edge of the top plate 5 are connected by a thin hinge 7.

The thin wall portion 4c is provided so that when the nozzle 6 is tilted forward as shown in FIG. 2, it is elastically inverted so that the lower end opening surface 6a of the nozzle is sealed by the front surface of the rear wall 4a. For this reason, the thin wall portion has a shape in which the truncated cone is cut from the rear end of the upper end to the front obliquely downward, and the lower portion is removed thereafter. The lower edges of the left and right side wall portions of the thin wall portion are connected to the upper edges of the aforementioned triangular side wall portions 4b, 4b. Therefore, the planar shape of the triangular side wall portions 4b, 4b is formed in an arc shape that matches the curve of the lower edge of the thin wall portion as shown in FIG.

The upper portion of the nozzle 6 may be bent forward as shown in the figure. In the illustrated example, the nozzle opening end face 6b is provided so as to be sealed by the front upper surface of the top wall 2 when the nozzle falls, and the upper surface of the nozzle opening is provided. An engaging projection 8 is additionally provided, and a hook 9 rising from the front of the top wall is detachably engaged with the engaging projection 8.

The cap is integrally formed of a synthetic resin material having high flexibility.

[0012]

According to the present invention, the cylindrical base 4 is opened by opening the top wall of the cap, and the nozzle 6 is raised by opening the top plate of the base, and the nozzle is formed into a flat plate. Triangular side wall portion 4 surrounded by a line connecting the upper and lower ends of the rear portion of the side wall and the lower end of the front portion of the left and right side walls.
b and 4b are formed into a rigid thick wall portion and the remaining cylindrical base forming wall portion is formed as an elastically deformable thin wall portion 4c, and the upper end of the rear wall and the top plate 5 are connected by a thin hinge 7. Since the thin wall portion is formed into a part of a truncated cone which can be elastically inverted when the nozzle 6 is tilted forward, the nozzle can be raised and lowered by elastic inversion. Is provided so that the lower end opening surface 6a thereof is in close contact with the front surface of the rear wall 4a, so that the nozzle can be opened and closed easily and reliably.
