Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns a synthetic resin pouring cap.

``Problems to be solved by conventional technology and ideas'' Conventionally, this kind of device has a dome-shaped spout head that is opened and closed with an arch-shaped spout that can be raised and lowered freely. be.

The present invention is to equip such a pouring cap with a convenient virgin seal type stopper,
It is intended to be convenient for use.

``Means for Solving the Problems'' The present invention consists of a spout head 2 which is dome-shaped from the center of the top wall of the cap body 1 and has a spout 21 at its tip.
is protruded from the cap body 1, and an arch-shaped spout 3 that straddles the spout head 2 and closes the spout 21 is connected to the outside of the cap body 1 so as to be bendable and extensible via thin hinges 32, 32.
Further, a half-cylindrical stopper 4 with a knob piece 42 attached to one half of the outer surface of the spout head 2 bordering on the spout 3 is provided.
, and both ends of the stopper 4 are connected to the spout 3 via thin broken pieces 41, 41 so as to be breakable and removable.

``Function'' It has the above structure and is used by attaching it to the mouth A of the bottle containing liquid, powder, granules, etc., but when pouring out the contents, first press the knob 42 of the stopper 4. The stopper is removed by pinching it and pulling it around (FIG. 2) to break the thin broken pieces 41, 41. Next, if the spout 3 is pinched and pushed forward or backward and tilted using the thin hinges 31, 31, the plug portion 3 will be deformed with appropriate elastic deformation of each member.
1 is separated from the spout 21, and the detached state is maintained due to its elastic deformation, and the spout 21 is opened. Then, tilt the bottle so that the spout faces downward and pour out the contents. After dispensing, if the spout 3 is moved backward, the mouth will return to the closed state.

"Example" The illustrated embodiment will be described below.

In the figure, 1 is a cap main body, 2 is a pouring head protruding from the center of the top wall of the cap main body, and 3 is a cap main body.
4 is a flexible spout that straddles the spouting head and closes the spout 21 thereof; 4 is a semi-cylindrical stopper that fits into one half of the spouting head and has both ends connected to the spout so that it can be broken and removed. These are suitably made of synthetic resin.

The cap body 1 has a large circular hole 12 in the center of a horizontal top wall 11, and a thread 14 on the inner periphery of a peripheral wall 13 that hangs down from the periphery of the top wall 11.
It is screwed onto the outside of the mouth A of the bottle.

The spouting head 2 is formed into a dome shape that fits into the through hole 12, has a small through hole spout 21 at its tip, and has a plug-like base 22 at its lower end so as to fit into the through hole 12. The base 22 is inserted from below and protrudes outward.
is fitted inside the mouth A of the bottle.

The spout 3 straddles the spout head 2 and has an inner edge facing the spout head 2.
A plug part 31 is formed into a plate shape in contact with the outer surface of the plug part 31 and has a small protrusion fitted into the spout 21 at the center of the inner edge of the plug part 31.
is provided protrudingly, and its both ends are integrally connected to the outer surface of the top wall 11 of the cap body 1 via thin hinges 32, 32.

The stopper 4 is formed into a semi-cylindrical shape corresponding to one half of the outer surface of the spout head 2 bordering on the spout 3, and is fitted onto the outer surface of the half, and has both ends attached to the spout 3 with thin broken pieces 41, 41. They are integrally connected to each other so as to be breakable and removable, and furthermore, a knob piece 42 is integrally provided on the outer surface of one end.

The cap body 1, the spout 3, and the stopper 4 are integrally formed by injection molding.

"Effect of the invention" According to the present invention, a virgin seal type stopper 4 can be installed, and the stopper prevents the spout 3 from opening unexpectedly during the product distribution process. The stored contents will not flow out from the spout 21 during the product distribution process,
Moreover, the presence of the stopper 4 makes it possible to guarantee the quality and value of the product.

Furthermore, after the breakage of the stopper 4 is removed, the spout 21 can be opened and closed very easily by bending and stretching the spout 3, and the stopper 4 is semi-cylindrical and fits into one half of the outer surface of the spout head 2. , since it is connected to the spout 3 via the thin broken pieces 41, 41 at both ends, the spout 3 after the stopper fracture is removed.
The broken end surfaces of the thin-walled broken pieces 41, 41 are located on both sides of the spout head 2 and below the spout 3, and do not touch the fingers when operating the spout 3. There will be no injury to the skin, no unpleasant tactile sensations, and no loss of beauty.

Furthermore, if the spout 21 is closed, dust and germs can be prevented from entering, the contents will not leak out even if the spout 21 falls, and opening and closing can be confirmed at a glance, and the spout head 2 is dome-shaped. It is suitable not only for dispensing the contents, but also for shaking, dropping, rubbing, etc., and is extremely convenient and useful.
