Description

[Detailed explanation of the idea] "Industrial application field" This proposal concerns pouring caps.

``Problems to be solved by conventional techniques and ideas'' Conventionally, a spouting cap having a spout on the front surface of the cap peripheral wall has been known. But in this case,
Since the spout is exposed, dust and the like can enter through the spout, and the contents can leak out due to falling over.

In order to solve this drawback, the present applicant previously proposed a device in which the spout is mechanically linked to the appearance and retraction by opening and closing the lid pivoted on the cap body (Utility Application No. 58). −119228).

As part of these efforts, this proposal attempts to provide a pouring cap with a new structure.

``Means for Solving the Problems'' In the present invention, a pair of left and right upright walls 12, 12 are protruded from the upper surface of the top wall 11 of the cap body 1, and a pair of left and right upright walls 12, 12 are provided on the inner surface of both the upright walls along the top wall 11. Guide groove 13,
13, the lid body 3 is pivotally attached to the rear of both upright walls so that it can be raised and lowered, and a tongue piece 35 is provided to protrude forward from the lower end of the boss 32 of the lid body through a hinge 34 so as to be flexible and extendable. A small ring 37 that opens in the front and back is connected to the tip of the tongue via a hinge 36 at the top,
A pair of protrusions 38, 38 are protruded from both sides of the outer periphery of the ring, and the protrusions are slidably fitted into the guide grooves 13, 13, so that the ring 37 is attached to both the upright walls 1.
It is installed so that it can move forward and backward between 2 and 12, and the top wall 11
A window hole 15 is bored in the center between the two upstanding walls 12, 12, an inner plug 2 is fitted and fixed to the upper inside of the cap body 1, and a small cylinder 21 is protruded from the center of the upper surface of the inner plug 2. The rear end of the flexible pipe 4 is fitted into the small cylinder, and the middle part of the pipe is loosely inserted into the window hole 15 and curved forward, with the tip protruding forward. The structure is characterized in that the vicinity of the tip of the pipe is fitted into the ring 37 so that it can move forward and backward according to the ring 37, and the middle part of the pipe is bent and closed when the tip retreats.

"Operation" Since the above structure is as follows, the pressing protrusion 31 of the lid body 3
When you push up and open the lid 3 (Fig. 1),
The tongue piece 35 extends, and the ring 38 moves into the guide groove 13,
13 and moves forward, and the tip of the pipe 4 protrudes forward.

Next, when the lid body 3 is closed (Fig. 2), the tongue piece 35
is bent and contracted, the ring 38 retreats, and the pipe 4
At the same time that the tip of the pipe 4 sinks into the inside of the lid 3, the middle part of the pipe 4 is broken and the flow path is closed.

"Example" The drawings show an embodiment of the invention.

The cap shown in the figure is provided with a cap body 1 made of synthetic resin, and the cap body has a top wall 11 formed in an inclined shape with a high front and low back, and a pair of left and right upright walls 12, 12 protruding from the upper surface of the top wall. A pair of left and right guide grooves 13 are provided at the intermediate portions of the inner surfaces of both upstanding walls and slope along the top wall 11.
13, and a pair of left and right bearing recesses 14, 14 are provided at the rear of the inner surface above the guide groove, and a window hole 15 is bored in the center of the top wall 11.

In addition, the cap body 1 has an inner plug 2 made of synthetic resin fitted and fixed in the upper part of the inside, and the inner plug has a small cylinder 21 protruding from the center of the upper surface to open the inside and outside. A fitting cylinder 22 which is inclined along the top wall 11 is erected, and the fitting cylinder 22 is fitted into the upper part of the inside of the cap 1 using the fitting cylinder.

In the figure, 16 is the peripheral wall of the cap body, 17 is
This is a thread provided on the inner periphery of the peripheral wall.

A lid 3 made of synthetic resin is placed on top of the cap body 1 to cover the top surface of the cap body, and a pressing protrusion 31 is provided protruding from the rear surface of the lid, and a boss 32 is inserted from the rear of the bottom surface. Both the upstanding walls 12, 12 are integrally vertically provided, and a pair of cantilever shafts 33, 33 are protruded from both sides of the boss, and the shafts are fitted into the bearing recesses 14, 14. In addition, a flexible tongue piece 35 is provided at the lower end of the boss 32 via a thin hinge 34 to protrude forward as the lid is opened and closed, and a thin hinge 36 is attached to the tip of the tongue piece. A small ring 37 is arranged in series through the ring, and a pair of protrusions 38, 38 are protruded from both sides of the outer periphery of the ring, and the protrusions are slidably fitted into the guide grooves 13, 13 to form a ring. 37 is attached between both the upright walls 12, 12 so as to be freely movable forward and backward.

The rear end of the flexible pipe 4 made of synthetic resin is fitted into the small tube 21, and the pipe's middle part is loosely inserted into the window hole 15 and curved forward, with the tip protruding forward. The structure is such that the vicinity of the tip of the pipe is inserted into the ring 37 so that it can move forward and backward according to the ring 37, and the middle part of the pipe is bent and closed when the tip retreats.

Thus, the cap body 1 is screwed onto the opening 51 of the squeeze container 5, which has a thread 52 around the outer periphery of the opening.

"Effect of the invention" According to the present invention, as the lid body 3 is opened and closed, the outlet, that is, the pipe 4, appears and disappears, and the middle part of the pipe 4 stretches and breaks, opening and closing the flow path. In addition, when not dispensing, dust and water do not enter the spout, and the contents do not leak out unexpectedly. Moreover, the structure is simple, and the flow path can be opened and closed by bending and stretching the pipe 4. It can be performed accurately, and the operation can be performed extremely easily with a single touch, which is extremely useful in practice.
