Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a stopper provided at a content mouth and a lid rotatably provided on the stopper, and more specifically, in a wide-mouth container. The present invention relates to a lid used as a stopper.

(Prior Art) Conventionally, shochu for fruit sake is often sold in a container such as a wide-mouthed bottle, and the soaked sake is transferred to another container or used while being soaked in the wide-mouthed bolt. It is forced.

Thus, the lid of the wide-mouthed bottle is an assembly or inner stopper system of the wide-mouthed cap and the packing, and in any case,
In most cases, liquor in the container was pumped out with a uniform pattern.

Although an inner plug with a spout may be used in some cases, it is necessary to provide an air hole in the inner plug in order to pour out a low-viscosity liquid without causing pulsation.

However, there is a problem that dust and the like enter the inside of the container through the air holes, which is not desirable from a hygienic point of view.

Further, there is also a problem that the liquid jumps out from the air holes when the liquid in the container is poured. Such liquid spillage can be prevented by using a two-stage pouring outlet, one of which is an air hole, a valve with a floating float, a diaphragm valve, etc., but the mold structure used for formation is complicated. Since the number of articles increases, the cost increases and it is not an appropriate means for general-purpose food product caps.

Therefore, an object of the present invention is to provide a lid body which can be effectively used as an inner plug with a spout having an air hole.

Another object of the present invention is to provide a lid body with an air hole in which dust is effectively prevented from entering through the air hole.

Another object of the present invention is to provide a lid with an air hole, which has a simple structure of the air hole and is extremely easy to mold.

(Means for Solving the Problems) According to the present invention, in a lid body including a stopper provided at a container mouth and a rotary spout rotatably provided on the stopper, the ceiling of the stopper is provided. An air hole and a cylindrical protruding portion are formed in the surface portion, the cylindrical protruding portion is formed at a position eccentric from the center of the top surface of the stopper, and the side wall portion of the protruding portion has a container. An opening communicating with the inside is formed, and the rotary pouring body includes a cylindrical support rotatably supported by the cylindrical protrusion and a part of a side wall of the support integrated with the cylindrical support. A thin film having an apex on the container side at an opening for an air hole formed in the top surface of the plug body, It is formed by providing a conical body and providing a plurality of cut lines toward the apex of the conical body. At the time of pouring the contents of the container, by rotating the rotary pouring body, the opening provided in the cylindrical protruding portion of the stopper and the pouring of the contents provided in the pouring body When the contents are poured out by communicating with the passage and the contents of the container are not poured out, the air holes are covered by the lower surface of the contents discharging protrusion of the rotating body. A lid body is provided.

(Operation) The lid of the present invention is characterized in that the air hole provided on the top surface of the stopper is arranged at a position where it is covered by the rotary spout.

That is, when pouring out the liquid in the container, the rotary pouring body is rotated to bring the pouring projection into a predetermined position. Effectively acts as a hole.

Thus, when the liquid in the container is not being poured out, the rotary pouring body is located at such a position that the projecting body for pouring covers the air holes, and therefore the normal unused body is not used. In this state, dust and the like are effectively prevented from infiltrating into the container through the air holes.

In the present invention, the structure in which the air hole is covered with the spouting protrusion of the rotary spouting body does not mean that the air hole is completely closed. It suffices that the pouring projections are located at intervals that can effectively prevent the intrusion of, for example, the pouring projections need not be in close contact with the air holes.

Further, in the present invention, it is extremely important to form the air holes by using a thin-film cone and providing a plurality of cutout lines toward the apex of the cone. That is,
By adopting such a structure, the air hole acts as a check valve and introduces air into the container to quickly pour out the content liquid, but the outflow of the content liquid through the air hole is effective. Will be prevented.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 schematically shows the overall structure of the lid of the present invention. The lid is a plug 1 fitted into the mouth of a wide-mouthed container and a rotary pouring rotatably provided on the plug 1. It consists of body 2 and.

An air hole 3 is formed in the top surface of the stopper 1 to effectively pour out the liquid content in the container, and a guide 4 is further provided.

In the lid body described above, the plug body 1 is formed of a soft resin such as polyethylene, and the spout 2 is formed of a hard resin such as polypropylene. These can be manufactured by a molding method known per se such as injection molding.

FIGS. 2-A and 2-B are plan views of the lid of the present invention when the liquid content in the container is being poured out and stored.

As is clear from these drawings, the rotary pouring body 2 is arranged at a position eccentric from the central portion of the stopper body 1, and thus when the container content liquid is pouring out, by rotating the support body 5. The projecting body 6 projects from the plug body 1 (see FIG. 2-A), and the liquid is effectively poured from the projecting body 6.

Further, the air hole 3 formed on the top surface of the stopper 1 is located near the guide 4, so that the protrusion 6 can be accommodated during storage.
However, the air hole 3 is covered, and the tip of the protrusion 6 (that is, the liquid pouring portion) is protected by the guide 4. (See Figure 2-B).

Thus, at the time of storage, dust, through the air holes 3,
Dust and the like are effectively prevented from entering the container, and the tip of the protrusion 6 is also protected by the guide 4.
It has excellent hygienic properties.

The structures of the stopper 1 and the rotary spout constituting the lid of the present invention will be described in detail below.

First, in FIGS. 3A and 3B showing a perspective view and a side sectional view of the plug body 1, a circumferential projection 11 is provided inside the outer wall 10, and the outer wall 10 and the circumferential projection 11 are provided. A groove 12 is formed between them. That is, the container mouth is fitted in the groove 12,
The stopper 1 is fixed to the container.

The top surface 1a of the plug 1 is a substantially flat surface, and the air hole 3 and the guide 4 are formed as described above.

A recess 20 is formed in the top surface 1a at a position eccentric from the center of the top surface 1a. A cylindrical projection 21 is formed in the recess 20 and a circumferential projection 22 is provided outside the cylindrical projection 21. Has been formed.

As is clear from FIG. 3-B, the cylindrical protruding portion 21 is higher than the top surface 1a, and its side wall portion is
An opening 25 is provided in 21a, and the opening 25 communicates with the space inside the container.

The opening 25 is preferably located at the upper end of the side wall 21a and extends completely from the molding point of view (for die cutting) to the top surface 21b of the cylindrical projection 20. .

Further, a stopper 26 is provided outside the circumferential protrusion 22.

Further, in the perspective view and the side sectional view of the rotary pouring body 2 as seen from the outer side, respectively, in FIG.
And a side wall portion 5a of the support body 5 and a pouring projection 6 integrally provided with the side wall portion 5a.

Inside the cylindrical support 5, concentric circular projections 30 are formed at a predetermined distance from the side wall 5a.

Further, a passage 31 for pouring out the content liquid is formed in the pouring projection 6, and the passage 31 extends from the tip of the projection 6 to the circumferential projection 30.
Extends to the position.

Further, a stopper 32 is provided on the outer side of the circumferential projection 30, and a packing 33 is provided in a portion partitioned by the circumferential projection 30, if necessary, to prevent liquid leakage from the passage 31. .

In the lid of the present invention, the cylindrical protruding portion 21 of the stopper 1 is the spout 2
The circumferential projection 22 of the plug 1 is fitted into the inner space of the circumferential projection 30 of the
The spout 2 is fitted into the plug 1 so that the spout fits with the support 5 of the spout 2.

That is, by rotating the pouring body 2, the opening 25 provided in the cylindrical protruding portion 21 communicates with the content liquid pouring passage 31, and the pouring of the content liquid is performed in this state. In this case, the pouring position of the pouring body 2 is defined by the engagement of the stoppers 26 and 32.

Thus, according to the lid of the present invention, the solution in the container can be easily poured out by rotating the rotary pouring body 2 and positioning it at a predetermined position.

Further, in the present invention, the air hole 3 provided in the plug body 1
Is required to have a structure that prevents the liquid content in the container from escaping from the air holes 3.

 The structure of the air holes 3 is enlarged and shown in FIG.

That is, a thin film cone 40 is provided below the opening formed on the top surface 1a of the plug 1, and a plurality of cutout lines 41 are formed from the top wall 1b toward the apex of the cone 40. An air hole is formed by the cutout line 41, and a portion 40a of the cone 40 defined by the cutout line 41 constitutes a valve.

This action will be described with reference to FIGS. 6-A and 6-B. For example, when the container content liquid presses the cone 40,
40a moves upward, and the gap formed by the cutout line 41, that is, the air hole is closed (see FIG. 6-A). Therefore, it is possible to effectively prevent the liquid in the container from jumping out of the air holes.

On the other hand, when the liquid content in the container is poured out, the internal pressure of the container is reduced, so that the portion 40a drops downward, and the gap formed by the cutout line 41 becomes large, so that air from the outside is removed. It flows in and acts effectively as an air hole (see FIG. 6-B).

The valve action described above is effectively achieved by setting the thickness of the thin film forming the cone 40 to about 0.15 to 0.3 mm, but it is not necessary to set the entire thickness of the cone 40 to the above range. By making only the thickness of the base portion of the cone 40 thin as described above, each portion 40a can have a good hinge action and can effectively act as a valve.

Thus, according to the present invention, it is possible to effectively prevent the liquid content of the container from escaping from the air hole with a simple structure, and to effectively achieve the function as the air hole when pouring out from the liquid content.

Incidentally, it is preferable that the above-mentioned air hole is sealed by providing a suitable stopper at the time of sale or the like, and the stopper is removed in actual use.

The lid of the present invention is combined with an outer lid, if necessary, and is effectively used as an inner stopper used in a wide-mouth container for shochu for fruit wine such as plum wine.
