BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a synthetic resin container cap for use in a container such as a bottle.

[0002]

2. Description of the Related Art A conventional cap for a synthetic resin container opening is disclosed in Japanese Utility Model Laid-Open Publication No. 1-107564. In brief, a liquid spouting lid having a peripheral wall constituting a spout and a canopy are connected by a hinge, and the bottom of the peripheral wall is hermetically sealed with a horizontal bottom plate. A weakening line is defined to form a spout, a knob is fixed on the hinge side defined by the weakening line, and a groove is formed in the bottom plate around the weakening line, and the slope is inclined toward the weakening line. The surface is provided. In addition, actual opening 54-8045
In Japanese Patent Publication No. 5 (1993) -1995, a hemispherical shielding wall is provided so as to seal the bottom of a flange-shaped raised portion forming a spout, and a weakening line is defined at the bottom of the shielding wall so as to open an elongated interstitial groove. There is disclosed a device in which a knob is fixed to one end defined by the weakening line. In addition, Japanese Utility Model Laid-Open Publication No. 59-77480 discloses a spout guide for forming a spout at the top of a cap body.
A horizontal top surface is provided so as to seal the bottom of the spout guide projection, and one end is circular and the other end is semicircular on the top surface, and the width is larger than the diameter of the circle and the semicircle so as to connect the two. There is disclosed a narrow and elongated portion, and the circle and the semicircle are divided by a weakening line, and a circular portion defined by the weakening line is provided with muquilling.

[0003]

[Problem to be solved by the invention] In the above conventional example,
JP-A-1-107564 and JP-A-59-77.
Any of the structures disclosed in Japanese Patent Publication No. 480 has the following problems to be improved since the bottom plate or the top surface is horizontal. That is, the remaining liquid poured from the spout by tilting the container is scattered over the entire bottom plate or top surface provided horizontally, and it takes time for the liquid to flow down into the container from the portion opened by the weakening line. In some cases, the flow may be static and adhere to the surface of the horizontal bottom plate or the top surface portion as it is, and there is a problem to be improved, especially in the case of soy sauce or sauce, which is not preferable for sanitation. Also, when pulling the muquilling etc. to break from the line of weakness and opening that part, if the bottom plate etc. is horizontal, the direction of the force pulling the muquilling with respect to the horizontal plane of the bottom plate must be at an acute angle rather than a right angle No. For this reason, a concentrated force is applied to the elongated portion partitioned by the weakening line, and the elongated portion is broken, so that the width of the elongated portion cannot be reduced too much. For this reason, there is a problem that the discharge amount of the liquid from the elongated portion increases, and it becomes difficult to finely adjust the amount of the liquid to be poured. Next, the one disclosed in Japanese Utility Model Laid-Open Publication No. 54-80455 in which the shielding wall is hemispherical is advantageous in that the remaining liquid is adhered as compared with the case where the bottom plate or the like is horizontal. When the container is set up vertically after pouring the liquid, the remaining liquid is still scattered over the entire surface of the shielding wall, and in the case of a highly sticky source, it may adhere to the shielding wall and remain. And there is a problem to be improved, which is unfavorable for hygiene. In addition, when the knob is pulled to break from the line of weakness and open that part, if the shielding wall is hemispherical, the direction of the force pulling the knob against the spherical surface of the shielding wall is more acute than at a right angle. There will be a pulling part. Then, a concentrated force is applied to the elongated portion partitioned by the weakened line of the portion pulled at the acute angle, and the elongated portion is broken, so that the width of the elongated portion cannot be reduced too much. For this reason, there is a problem that the discharge amount of the liquid from the elongated portion increases, and it becomes difficult to finely adjust the amount of the liquid to be poured. Next, in the case where the opening sectioned by the weakening line is horizontal or hemispherical, if the container is inclined and the liquid is poured, the area in which the opening section is closed by the liquid increases, and the air inflow correspondingly increases. Since the area is narrowed and the liquid flow is poor, the elongated portion cannot be made very thin, and there is a problem that the fine adjustment of the injection amount becomes difficult as described above.

[0004] The present invention eliminates the problem of sanitary problems by preventing the remainder of the pouring from spilling over the bottom plate and the like, prevents excessive force from being applied when breaking from the line of weakness, and ensures a sufficient air inflow area. The present invention provides a cap for a synthetic resin container opening, which is made thinner as far as it protrudes from the slender part, and further enables fine adjustment of a pouring amount.

[0005]

Means according to the present invention for solving the above-mentioned problems include a body having a pouring wall and a lid.
For container opening made of synthetic resin, which is connected by hinge
, A sealing wall for sealing the bottom of the pouring wall
The sealing wall is raised on the hinge side,
The sealing wall shall be lowered in the direction away from
Form circular parts at both ends along the direction and connect these circular parts
An elongated part narrower than the diameter of the circular part and
The circular portion is defined by a line of weakness, and
The handle is connected to the circular part on the side of the flange, and it is divided by the weakening line
It is characterized in that both sides of the sealing wall are inclined planes

[0006]

The present invention has the following operation. In other words, to seal the bottom of the pour wall
The sealing wall of the hinge part side higher and away from the hinge part side
Sealing with inclined surface lowered in the direction and partitioned by weakening line
Due to the inclined plane on both sides of the wall, the remaining liquid flows down the inner surface of the pouring wall and flows down to the lowest point of the inclined sealing wall. And both ends along the inclination direction of the sealing wall
A circular portion is formed on the circular portion so as to connect the circular portion.
Weaken the slender part and the circular part, whose width is smaller than the diameter
Since the compartment by the line, the liquid flowing down along the inner surface of the pouring walls, intensively flow down a circular opening which is provided at the lowest side of the sealing wall which is inclined. Also, the weakening line
In so connecting the handle to the circular portion of the compartment and said hinge portion side, the inclination angle of the sealing wall which is inclined, so as not to an acute angle to the plane of the sealing wall which is inclined to a direction to pull the handle In addition, the angle can be substantially right.
And furthermore, since the sealing wall is inclined so as to become lower in the direction away from the hinge portion, in a state where the container is inclined and the liquid is poured along the pouring wall, the weakening line is closed by the liquid in the container. The opening area can be minimized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. The cap consists of a body 1 and a lid 2,
Both are integrated by a hinge part 3.

The body 1 is substantially cylindrical and has an outer wall 14 and an outer wall 14.
An annular container opening fitting wall 15 hung down at an appropriate distance from the inner surface of the outer wall 14 on the inner side of the lower half, and a circle erecting a liquid return groove 16 on the inner side of the upper half of the outer wall 14. Arc-shaped pour wall 17
A sealing wall 18 for closing a portion surrounded by the pouring wall 17, an elongated annular weakening line 19 formed in the sealing wall 18, and a weakening line 19
And a handle 20 integrally connected to the handle.

An annular shoulder 21 is formed at an intermediate portion of the outer wall 14, and an inwardly projecting annular tongue is formed at an upper edge of the outer wall.
22 are formed.

The liquid return groove 16 is inclined rearward of the pouring wall 17, that is, rightward in FIG. 1, so that the liquid can easily flow into the pouring wall 17 as described later.

As shown in FIGS. 1 and 2, the pouring wall 17 has a cutout at the rear of the pouring wall 17 (on the side of the hinge 3), and the portion away from the hinge portion 3 is higher. The liquid formed and flowing into the return groove 16 flows into the pouring wall 17 from this opening.

As is apparent from FIG. 1, the sealing wall 18 is inclined so that it is higher on the hinge 3 side and lower in the direction away from the hinge 3. As shown in FIG. 3, the shape of the weakening line 19 formed on the sealing wall 18 is such that the elongated rectangle 19C and the circles 19A and 19B located on both sides thereof are connected along the inclination direction of the sealing wall 18. It has a shape.
The circle 19A provided on the lowest side of the inclined sealing wall 18 is a main spout, and the circle 19B provided on the highest side is an air inlet at the time of pouring.

The weakening line 19 extends diametrically at the center of the sealing wall 18. This portion is a flat portion 24 of the sealing wall, and a pair of inclined planes 23, 23 which are inclined toward the weakening line from both sides in a direction orthogonal to the weakening line 19, are formed.

The lid 2 connected by the hinge 3 is connected to the trunk 1
A cylindrical seal wall 27 having an outer diameter dimension that abuts the shoulder portion 21 and fits on the upper portion thereof is formed inside the cylindrical outer wall 26 at an appropriate interval. Seal wall 27
Is protruded from the ceiling of the lid 2 at a position where it comes into contact with the inside of the upper edge of the trunk 1 when the lid 2 is covered with the trunk 1.

As shown in FIGS. 1, 5, and 6, the cylindrical sealing wall 27 has a wedge-shaped annular concave portion 28 at its end face, and an inner edge thereof is an annular tongue 29. Accordingly, when the cover 2 is covered with the body 1, as shown in FIG.
The concave portion 28 and the tongue 29 of 27 cooperate with the inwardly protruding tongue 22 of the upper edge of the body 1 to form contact points A and B, and seal between them in a liquid-tight state.

[0016]

According as the present invention described in detail [devised effects above, pouring
The sealing wall to the bottom wall in a sealed, high hinge portion
The sealing wall shall be lowered in the direction away from the hinge part side, and both sides of the sealing wall demarcated by the line of weakness shall be inclined planes . As it flows down to the lowest point, the remaining liquid does not scatter throughout the sealing wall. And the sealing wall
Circular portions are formed at both ends along the inclination direction of
Slender, narrower than the diameter of the circular part to tie
The liquid flowing down along the inner surface of the pour wall divides the portion and the circular portion with a line of weakness, and the liquid that flows down along the inner surface of the inclined sealing wall flows down intensively into the circular portion opening provided on the lowest side of the inclined sealing wall. All the liquid can be returned into the container without adhering to the sealing wall, and unsanitary conditions can be reliably eliminated. Also, a circle on the hinge part side sectioned by a weakening line
Since the handle is connected to the portion and the inclination angle of the inclined sealing wall, the pulling direction of the handle can be set to a substantially right angle so as not to be acute with respect to the surface of the inclined sealing wall. When the weakening line is broken, a large force concentrated on the elongated portion is not applied, so that the thinned portion can be narrowed as far as the width of the elongated portion is exceeded, and the amount of pouring can be finely adjusted. Further, the sealing wall is inclined so as to become lower in a direction away from the hinge portion, and in a state where the container is inclined and the liquid is poured along the pouring wall, the opening area due to the weakening line closed by the liquid in the container is reduced. Since it can be minimized, the air inflow area can be sufficiently ensured even when the elongated portion is made thinner, so that smooth pouring can be performed and the amount of pouring can be finely adjusted.
