Description

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

``Problems to be solved by conventional techniques and ideas'' Conventionally, as a pipe port sealing device, a pipe protruding from the pipe port, a nut screwed onto the pipe port, and the pipe plug being attached to the nut. A U-shaped closing actuation piece that opens and closes the
There is a device in which frictional engagement means using a lurette and small protrusions is provided between the spout and the closing actuating piece to provide frictional resistance to the rotation of the closing actuating piece.
-20544 Publication).

If such a device could be used as a pouring cap, the spout could be opened and closed easily, but since this tube port sealing device has a spout protruding from the tube mouth, that is, from the side of the container body, It cannot be used as is, and
If all of this were to be implemented on the pouring cap, the structure of the pouring cap would be extremely complicated and would look unsightly.

The present invention takes these matters into account and attempts to provide a simple, convenient, and beautiful pouring cap whose spout can be opened and closed with a single touch.

``Means for Solving the Problems'' The present invention provides an upwardly protruding bulge 13 on the top wall 12 of the cap body 1 on which the outer cylinder 2 is fitted and fixed.
is provided, and a spout 14 is bored at the tip of the bulge,
In addition, a plug part 31 is pivotally connected to the cap body 1 to the outer cylinder 2.
A pair of left and right square shaft holes 23a, 23a are formed in the shaft holes, and a pair of left and right shafts 32, 32 protruding outward from both ends of the plug body 3 are rotatably fitted into the shaft holes. The radius of the shaft is formed to a dimension A+α that is slightly larger than the half width A of the shaft hole, and the fit is made somewhat firmer.

``Function'' The structure is as shown above, and the cap body 1 is connected to the peripheral wall 11.
It is used by attaching it to the mouth of a bottle containing liquid, etc., but when dispensing, it is sufficient to rotate and tilt the stopper 3, and by this rotation, the stopper 31 is removed from the spout 31. It separates and the spout 31 opens. When closing again, the plug body 3 should be moved in the opposite direction, but in either the open or closed state, the shaft holes 23a, 23a and the shaft 32,
Since the fitting of 32 is somewhat tight, the rotation of the shaft is slow,
The stopper 3 maintains its position and does not move freely. Note that when the plug portion 31 enters and exits the spout 31, the plug body 2 is slightly elastically deformed.

"Example" The illustrated embodiment will be described below.

1 to 4 show an example of implementation, and in the figures, 1 is a cap main body, 2 is an outer cylinder fitted to the cap main body, and 3 is a circuit pivotally connected to the cap main body or outer cylinder. Dynamic plugs, which are suitably made of synthetic resin.

The cap body 1 is provided with a bulging part 13 whose tip protrudes semispherically at the center of a top wall 12 that is continuous with the upper end of the peripheral wall 11 , and a spout 14 is bored at the tip of the bulging part. An engaging protrusion 15 is provided around the lower part of the outer periphery, a thread 16 is provided around the inner periphery of the peripheral wall, and a short fitting tube 17 is provided vertically from the top wall 11 inside the peripheral wall.

The outer cylinder 2 fits on the outer periphery of the peripheral wall 11, has an engaging groove 21 around the lower part of the inner periphery, engages the engaging groove 15 with the engaging protrusion 15, and has an inner part at the upper end. A facing flange 22 is provided, and the flange is butted against the upper surface of the peripheral edge of the top wall 12, and a pair of left and right bearings 23, 23 are protruded from the upper surface of the flange.

The bearings 23, 23 have internal square cutouts 231, 231 with open inner and lower surfaces,
The notch and the upper surface of the peripheral edge of the top wall 12 form square shaft holes 23a, 23a.

The plug body 3 is formed into a vine shape corresponding to the bulging portion 13, and has a small hemispherical plug portion 31 protruding from the lower surface of the center thereof, which removably fits into the spout 14, and has both ends. A pair of left and right shafts 32, 3 that protrude outward
2 is provided protrudingly so that the shaft is fitted into the shaft holes 23a, 23a, and the radius of the shaft is formed to a dimension A+α that is slightly larger than the half width A of the shaft hole to achieve the fitting. It is made somewhat stiffer and the rotation of the shaft is made heavier to prevent free movement.

FIG. 5 shows another embodiment. In this case, the peripheral wall 11 of the cap body 1 is eliminated from the previous example, and the outer cylinder 2 also serves as the peripheral wall. Therefore, a thread 24 is provided around the outer cylinder 2 in place of the engagement groove.

"Effects of the invention" According to the present invention, a simple opening/closing means can be introduced into the spout cap, the stopper 3 can be rotated with one hand or one touch, and the opening/closing operation of the spout 14 can be performed extremely easily. The body 3 has the shafts 32, 32 slightly larger than the shaft holes 23a, 23a at the pivot joint to make the fit somewhat tighter, so it cannot move freely, that is, it cannot be moved to that position unless manually operated. Therefore, when opening, there is no chance of the liquid opening unexpectedly due to falling, etc., and the liquid will not flow out, and when opening, due to tilting, etc., it will not close unexpectedly or become a hindrance, causing inconvenience in pouring out the liquid. And since the material is synthetic resin and the shaft holes 23a, 23a are square, the shafts 32, 32 and the shaft holes 23a, 23
Even if the fit with a is somewhat tight in terms of dimensions, it allows for very slight elastic deformation, does not cause any strain, and can withstand long-term use. It is simple, easy to manufacture, inexpensive, and has a beautiful appearance.
