Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a spout with a cap that is attached to a paper container or the like to guarantee the contents.

(Prior Art) Conventionally, in order to secure the contents of the container, a bottle closure device in which a bottle cap having a cutout portion between a threaded portion and a ratchet portion is screwed onto the bottle opening has not been used in practical use. 1980-
This is described in Publication No. 158850.

(Problems to be Solved by the Invention) By the way, in the above-mentioned known bottle closing device, since the container is a bottle body, the object of the screw-locking of the bottle lid is:
The spout is a part of the bottle body, and it has been difficult to immediately convert it into a separate pouring spout that is attached to a container such as paper.

(Means for solving the problem) The present invention was devised in view of the above points. By screwing the Contents Guarantee Act cap onto the spout body, which is attached with a flange on the inside of the container, the outer surface of the container is clamped by the clamping flange on the locking part side of the cap, and
The locking protrusion prevents rotation in the unscrewing direction so that the locking part side does not move stably when separating the separation part to screw off the cap.

That is, in the present invention, the spout main body is provided with a mounting collar at the bottom of the screw barrel, a locking protrusion on the upper surface thereof, and a locking annular protrusion above the spout body, and a cap for securing the contents, There is a separation part between the locking part side and the cap part, and the locking part side of the cap cannot be removed after being locked to the clamping collar and the locking protrusion on the inside thereof. It is composed of a locking protrusion and a locking annular protrusion above the locking protrusion that locks below the locking annular protrusion.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

The present invention consists of a spout main body A and a cap B for securing the contents which is screwed onto the spout main body A. These are injection molded from synthetic resin and are used as a set.

The spout main body A includes, at the bottom of a screw tube 1 serving as a spout, a locking annular protrusion 2 extending in the circumferential direction, followed by a plurality of locking protrusions 3 having inclined surfaces in the clockwise rotation direction, and further following this. An attachment collar 4 is provided at the lower end of the container to be attached to the container body C of a container such as paper or an inner bag D within the container body.

In addition, the cap B for securing contents has a locking portion side a that locks on the locking protrusion 3 of the spout body A, a cap side b that screws onto the screw tube 1, and connects these two. It consists of a circumferential band-shaped separation part c for

The locking part side a has a locking protrusion 5 that locks with the locking protrusion 3 on the inside thereof, and a circumferential locking ring 2 on the top thereof.
, a circumferential locking annular protrusion 6 that locks on the lower side, and a clamping collar 7 on the outside, and the locking protrusion 5 rotates in the counterclockwise direction opposite to the locking protrusion 3. It has an inclined surface. Moreover, the hard part side b has a screw 8 screwed into the screw tube 1 on the inside thereof.
A packing 10 is provided on the top plate 9.

The separation part c is located between the locking part side a and the cap part side b, and has upper and lower thin-walled parts 11, 11, respectively.
, and some parts have a knob 12.
However, a through hole 13 is provided near the knob 12.

Furthermore, a temporary sealing lid plate 15 is attached to the mouth part 14 of the screw barrel 1 of the spout main body A to maintain a sterile state until just before filling the contents.
6 and 16 are attached to one body.

The spout with cap configured as above is
The spout main body A is attached to the container main body C by its mounting collar 4 either directly [FIG. 2A] or together with the inner bag D inside the container main body C [FIG. 2B].

Next, the cap B for securing the contents is screwed into the threaded cylinder 1 of the spout main body A with the screw 8 inside thereof. As the cap B screws forward, the circumferential locking annular protrusion 6 on the locking part side a abuts against the circumferential locking annular protrusion 2 of the screw tube 1. , the protrusion 6 rides over the protrusion 2, and the locking protrusion 5 on the locking part side a crosses over the protrusion 3 on the screw cylinder 1 side.
Then, they slide on their respective slopes and lock into each other.
At this time, the clamping pressure collar 7 on the locking part side a is pressed against the container body C.
and cooperates with the mounting flange 4 of the spout main body A to clamp it.

As mentioned above, the spout with cap of the present invention is
After attaching this directly to the container body C of a container such as paper or together with the inner bag D inside the container body C,
Even if an attempt is made to rotate the cap B in the counterclockwise rotation direction to unscrew it, the locking protrusion 5 on the locking part side a is stuck to the spout body A.
It is in a locked state with the side locking protrusion 3 and cannot rotate.

When pouring out the contents, first, the separating portion c of the strip is pulled by pinching its pinching portion 12, so that the thin-walled portions 11, 11 on both sides are successively separated from the through-hole 13 portion. Thus, the locking part side a and the cap part side b are separated.

Here, the cap side b is unscrewed and the contents are poured out, like a normal cap.

The temporary sealing lid plate 15 is necessary to maintain a sterile state until immediately before filling the contents, and is removed immediately before filling.

A spout similar to the present invention previously filed by the present applicant [Utility Application No. 56-98970 (Japanese Utility Model Application No. 58-5945)] is shown in FIG.

That is, this spout has a spout main body A′,
The spout body A' has a locking protrusion 2' on its threaded tube 1', and the cap B' is screwed onto the spout body A'.
The locking part side a', which has the locking protrusion 3' that locks with the locking protrusion 2', and the cap part side b' are connected to each other by a thin connecting part 4'. Protrusions 5' and 6' are provided on the opposing surfaces so that they lock together when rotated clockwise but slide against each other when rotated counterclockwise. Inner bag inside the container body C′ at the brim
It is attached to D', and the container body C' is clamped to the flange of cap B'.

Then, when the cap side b' of the cap B' is rotated to the left to unscrew it, the locking protrusion 3' of the locking part side a' is rotated to the locking protrusion 2' of the spout body A' side. Therefore, the cap part side b' breaks the narrow connecting part 4' and the protrusion 6' slides on the protrusion 5', and the cap part side b' slides over the protrusion 5', and the cap part side b' Side b' is adapted to be unscrewed.

In this case, a piece of the connecting portion 4' and a protrusion 6' remain on the end surface of the cap side b' after unscrewing.

(Effects of the invention) The present invention is capable of separating the separating part of the strip constituting the cap by pinching its grip and pulling it to separate the cap part side from the locking part side. Since it cannot be removed, this cap guarantees the contents, and if the cap is accidentally unscrewed or unscrewed due to unauthorized use, the locking part side and the cap part side will be damaged. The condition is obvious at a glance because there is a wide gap between the spout and the cap, and it becomes even more obvious when the spout itself and the cap are made of a different color.

This can prevent unnecessary trouble from occurring with consumers.

Moreover, the separation part can be easily separated by simply pinching and pulling the knob, but in this case, the locking annular protrusion on the locking part side extends beyond the locking annular protrusion of the spout barrel. Since it is locked at the bottom of the container, when it is separated, the locking part does not move at all as the clamping pressure flange presses the outer surface of the container body, making it stable and extremely easy to use. Moreover, since there is no connection residue on the separated facing surfaces of the separated cap part side and the locking part side, the cap looks good and feels good to the touch, and it is easy to use after unscrewing. Like a normal cap, the end surface does not touch anything, so it can be screwed on and removed smoothly.

Therefore, it is inexpensively produced by injection molding and has high utility value as a spout with a cap that guarantees the contents used in containers such as paper.
