Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spout that can control extraction and has an opening/closing function for use in a blow-molded container made of a flexible synthetic resin material and used to fill a substance (such as a shape).

Conventionally, the caps (cap lids) used for this type of container are screwed together, which takes time and effort, from a hygienic standpoint to prevent leakage of the aqueous solution or powder in the container.

Thus, the spout according to the present invention is completely different from the known ones, and is a deviation from the conventional one due to a new mechanism with a different spout structure.

In short, the present invention is based on Utility Model Registration Application No. 098 of 1985.
This is a spout with an improved configuration related to No. 091, and its container body is made by blow molding and is screwed into the oral cavity and used in combination, and its specific requirements are that the aqueous solution or paste to be filled into the container etc. (hereinafter referred to as "substances") can be extracted by lightly grasping the container with a raised hand and using a strong and weak motion.Also, the extraction can be arbitrarily stopped by a weak motion of the raised hand, but the container can be turned upside down, turned sideways, This device uses a new composition method that allows it to automatically open and close without leaking even if it falls over.

Therefore, with the spout according to the present invention, extraction is carried out one by one at will through the extraction hole drilled in the center of the lower part, and as mentioned above, when the hand is raised again, the extraction stops completely due to the counter pressure inside the container. , an extraction control spout that completely prevents leakage.

The present invention will be explained based on an embodiment according to the drawings.A spout made of a synthetic resin material such as polypropylene (P, P) as a main component is constructed by integrally engaging two parts. .

Therefore, for convenience's sake, the upper part is called A, and the upper part is called A.
The lower part will be referred to as B and will be explained.

Thus, A has a mouth-like main body (1) with an internal opening (2), a protrusion cavity (3) which is quickly narrowed at the bottom, and a concave groove (4) in the center of its outer periphery. establish.

Moreover, the bottom part (5) has a conical pyramid shape (7) formed at the center of the intersection of the raw or trifurcated support pieces (6), and a convex outer periphery made of a circular shape on the opposite bottom face is tapered. (16)
A protruding lid (15) is provided.

A space (8) is provided between each support piece (6) formed in this way.

Next, B is a cover lid (9) in the form of a dish-shaped mouth, which has an internal opening (10) and a convex groove (11) formed on its inner periphery, which engages with the groove (4). The inner diameter is configured to be held between the protrusion cavity chamber (3).

Therefore, this bottom hole (12) is curved along the inner surface, and an outflow hole (13) is bored in the center thereof.

The upper part of the inner surface of the outflow hole (13) is formed into a tapered shape (14), and in short, when a covering lid (9) that fits and engages with the bottom surface of the main body (1) is fitted, as shown in FIG. The bottom opening (12) has a curved shape and has a tapered shape (14) and a protruding lid (15) inserted into the expansion outlet hole (13).
16) is the structure of the spout to completely stop and control the outflow of the substance (17).

The spout according to the present invention is a container (18) of the embodiment shown in FIG.
A container (18) that is screwed or fitted into the oral cavity of the person.
The inside is filled with a substance (17).

As described above, the spout according to the present invention is configured to open and close automatically under pressure and counter pressure action.

Unlike today's spout lids, which do not require the hassle of having to remove them each time or turn the cap to use them, the present invention completely blocks leakage of substances, and is intended for extremely unusual and remarkable versatility. It is a spout that allows for

Claims (1)

[Claims] As shown in the figure, the spout is constructed by integrally engaging two parts, the upper part is called A, the lower part is called B, and the main body of A (
1) has an internal opening (2), the bottom part forms a slightly narrowed protrusion cavity (3), and a concave groove (4) is provided at the center of the outer periphery. ) is a +-shaped or three-pronged support piece (6
) is integrally formed with a conical pyramid shape (7) at the intersection center thereof, and a protruding lid (15) on the opposite bottom surface thereof. Therefore, B is a saucer-shaped covering lid (9) with an internal opening (1
0) and a convex groove (11) is formed on its inner periphery;
The inner diameter is configured so as to be held in the protrusion cavity (3). However, the bottom opening (12) is usually curved along the inner surface, and the outflow hole (13) is bored in the center of the opening/closing device.
