[Industrial applications]

 The present invention relates to a liquid pouring cap fitted into a container mouth by tapping, which can be easily removed from the container mouth after using an internal solution, with a plastic protector ring.

[0002]

[Prior art]

 Conventionally, a liquid pouring cap of a so-called pull opening type is widely used in which a thin ring portion is broken to open a pouring opening by pulling a pull ring integrally formed on a ceiling wall of a cap body. This type of cap is formed of a cap body that engages with the container mouth, and an upper lid that is separate from the cap body and that is screwed into the cap body, or an upper lid that is integrally formed with the cap body via a hinge. Then, the cap body is screwed or plugged into the mouth of the container to be fitted. On the other hand, recently, it has been called for to recycle containers from the viewpoint of resource saving and environmental conservation. In the case of plastic containers, used containers are crushed and used as recycled plastic raw materials. In that case, for example, in the case of a bottle that contained a seasoning liquid such as soy sauce or sauce, the salt content of the liquid remaining inside solidifies, mold or odor is generated, and if it is crushed as it is, it is regenerated. As a result, the quality of raw materials is degraded, which is an obstacle to recycling. Therefore, in order to promote the recycling of plastic containers, consumers are required to wash the bottles so that the seasoning liquid does not remain inside the containers after use. However, even if the consumer wants to wash the container, the spout opened on the cap body has a relatively small elliptical shape to adjust the spout flow rate, making it difficult to inject and spout the washing water. There's a problem. In addition, even if you try to remove the entire cap from the container mouth and try to pour water directly from the container mouth, in the case of a stopper type cap, because it is plugged with a strong force and fitted into the container mouth, There was a problem that it could not be easily removed, and it was difficult to clean the container fitted with the stopper cap.

On the other hand, in the conventional pull-opening type cap, at the time of distribution, the upper lid of the container at the store is removed, the pull ring is pulled up, and part or all of the opening is opened from the thin-walled score part to smell the contents. However, there was a problem that even a mischievous person could not understand the appearance even if there was a mischief such as mixing the foreign object and returning the top cover to the original position.

[0004]

[Problems to be solved by the device]

 The present invention has been made to solve the above-mentioned problems of the conventional stopper-type and pull-opening type liquid pouring caps, and its purpose is to provide a stopper-type cap. Even if there is, the entire cap can be easily removed from the mouth of the container for washing the container, and the liquid with the protector ring is displayed so that it can be seen visually that the top cover has been illegally opened during the distribution stage. The purpose is to provide a cap.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a liquid pouring cap with a protector ring of the present invention has a cap body, a cap body separately from the cap body, or an upper lid integrally formed via a hinge. In a liquid pouring cap in which the spout can be opened by pulling up the pull ring, and the outer wall of the cap body is fitted into the container mouth by tapping, a plurality of vertical slits are formed on the outer wall of the cap body. The protector ring is fitted on the outer peripheral portion of the outer wall of the cap body so as to be movable along the axial direction of the outer wall.

It is desirable that the slits formed on the outer wall of the cap body be formed at 3 to 6 positions at substantially equal pitches. Further, the protector ring has an outer peripheral wall that is closely fitted to the outer peripheral portion of the outer wall of the cap body, and is directed inward at the upper end of the outer peripheral wall so as to be located above the flange portion of the upper lid. By forming the thin blade piece for displaying the illicit opening of the upper lid, it can be determined that the upper lid has been illicitly opened at the distribution stage. By providing a protector ring, it is possible to remove the cap body from the container after using the internal solution, and also to perform the function of distinguishing the illicit opening before use. Further, the protector ring is formed in a color different from that of the cap body or the upper lid, so that fashionability can be enhanced.

[0007]

[Action]

 The outer wall of the cap body can be easily opened to the outside by providing the slit, but by fitting the protector ring to the outer wall, the outer wall of the cap body is restrained from opening to the outside and the container mouth is closed. With the cap fitted, it functions like a normal cap without slits. After using the content liquid, by sliding the protector ring upward from the outer wall of the cap body, the protector ring can be removed from the outer wall of the cap body, and the cap body can be easily removed from the mouth of the container to clean the container. You can easily. The blades of the protector ring gently touch the flange of the outer peripheral wall of the upper lid from above, and when you try to open the upper lid at the beginning of use, the flange of the upper lid warps upward and removes the collar. By fold it to fold it or sandwich it between the stepped wall of the cap body and the collar of the upper lid, it is possible to easily visually identify the unauthorized opening of the upper lid during the distribution stage.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, 1 is a cap body, 2 is an upper lid, 3 is a protector ring, and the cap of this embodiment is constituted by these three members. As shown in the cross section of FIG. 1, the cap body 1 is formed with an outer wall 6 on which a protrusion 5 that engages with an engagement protrusion of the container mouth is formed by tapping, and is concentric with the outer wall 6. An inner wall 7 in contact with the inner peripheral surface of the container mouth, a step wall 8 connecting the upper part of the outer wall 6 and the inner wall 7, and an outer lid screwing wall 10 formed with a screw extending from the step wall to the upper part to screw the outer lid. An outer cover, a spout 12 formed on a top wall 11 extending inward from the top of the threaded wall 10, and a bottom wall 13 of the spout surrounded by a thin wall score 14 to open the spout. It comprises a ruptured portion 15 that is open, and a pull ring 16 is integrally formed on the upper surface of the ruptured portion 15. As shown in FIGS. 3 (b) and 5, the outer cylinder 6 is formed with a plurality of slits 20 in the vertical direction, and by forming the slits 20, the container mouth is capped. The outer lid of the cap body can be easily removed from the mouth of the container. Although the number of slits 20 is six in this embodiment, it is desirable to form three or six slits 20 so that they can be easily removed and the fitting force can be maintained. Since the slits are formed on the outer wall, it is easy to force the die out of the mold during molding.Therefore, the underside for forming the protrusion that engages with the container mouth formed on the inner surface of the outer lid. A large amount of cut can be formed, and the fitting force of the cap with the container mouth can be strengthened.

Further, the upper lid 2 has a skirt wall 25 and a ceiling wall 26 in which screws to be screwed into the upper lid fitting wall of the cap body are formed. A spout barrel fitting wall 27 that is fitted to the peripheral surface and closes the spout barrel 12 is formed. A collar portion 28 is formed at the lower end portion of the scar wall 25 so as to engage with the upper surface of the step wall of the cap body.

Further, the protector ring 3 has an outer peripheral wall 30 that is tightly fitted to the outer peripheral portion of the outer wall 6 of the cap body 1, and has a notch 31 at the upper end thereof in equal pitches as shown in FIG. The blades 32 are formed so that the cutouts serve as the blade pieces 32. It is desirable that the blade pieces 32 are formed in 4th to 24th positions in terms of its effect. The protector ring is usually knurled on the entire inner surface of the ring so that it does not usually come off easily from the outer wall of the cap body, and after use it can be easily moved upward by removing it. To do. Since the protector ring is formed separately from the cap body, the fashionability of the cap can be enhanced by forming the protector ring with a resin having a different color from that of the cap body and the upper lid.

The cap of this embodiment is configured as described above, and the state in which the cap is fitted into the container by stoppering is shown in FIG. 1. In this state, the protector ring 3 is a slit in the cap body. Prevents the outer wall having a wall from opening outward, maintains the outer wall 6 of the cap body 1 tightly fitted in the container mouth, and the blade pieces 32 are located above the collar portion 28 of the upper lid 2, Lightly touches the collar from above. In this state, when the upper lid is rotated to remove the upper lid, as the upper lid rises, the blade portion 28 of the proctor ring warps upward as shown in FIG. Come off. When the upper lid 2 is tightened again, the collar portion 28 presses the blade piece and bends it so as to fold it downward so that it becomes as shown in FIG. 7B or the cap body as shown in FIG. A blade piece 32 is sandwiched between the step wall 8 of No. 1 and the collar portion 28 of the upper lid 2. Therefore, even if the upper lid is removed during the distribution stage and the upper lid is returned to its original position, it is easy to open because the blade pieces 32 are bent or sandwiched.

Further, when the container is discarded by using all of the internal solution, the protector ring 3 is moved upward from the state of FIG. 2B so that the ring restrains the outer lid 6 of the cap body 1. Solve In that state, the outer wall 6 of the upper lid can be easily expanded from the slit 20, and the projection 5 formed on the inner peripheral wall of the outer lid is disengaged from the projection formed on the container mouth, and the cap is removed. The main body 1 can be easily removed from the container opening. Therefore, the cleaning liquid can be directly injected and poured into the container from the container opening, the inside of the container can be easily cleaned, and the recycling of the container containing the seasoning liquid can be promoted. In the above embodiment, the upper lid is formed separately from the cap body, but the present invention is not limited to this embodiment, and the upper lid is integrated with the cap body by a hinge. It goes without saying that it can be applied.
