〈産業上の利用分野〉
本考案は、ネジ蓋とそれと螺合する注出口を有
する注出具に関し、特に、斜め締めを防止した注
出具を関する。[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a pouring tool having a screw cap and a spout screwed into the screw cap, and particularly relates to a spouting tool that prevents diagonal tightening.

常３〜８mm程度のクリアランスが存在する。<Conventional technology> Conventionally, in a screw-type dispensing tool in which the screw cap is rotated to tighten and seal the spout of the dispensing tool, the male thread of the spout and the female thread of the screw cap are located at the top and bottom of each peak. On the other hand, there is a gap (called a clearance) between the top of the mountain and the corresponding bottom of the valley. Although the clearance varies depending on the size of the pouring tool, there is usually a clearance of about 3 to 8 mm.

FIG. 3 is a cross-sectional view of a screw cap having a certain stepped portion.
第１図において、注出口１の外周は、山の頂４
の外径ｄ、谷底６の外径d1を有し、その最外端部
に段差部５を設けてある。 In Fig. 1, the outer circumference of the spout 1 is the top 4 of the mountain.
has an outer diameter d, and an outer diameter d1 of the valley bottom 6, and a stepped portion 5 is provided at the outermost end thereof.
また、他の実施例であるネジ蓋の場合、ネジ蓋
２の内周は、谷底６の外径Ｄ，山の頂４の外径
D1を有し、その最外端部に段差部５を設けてあ

所定の位置に正常に螺合される。 FIG. 3 is a cross-sectional view of the screw cap screwed onto an inlet having a stepped portion, and the outermost end of the spout has a diameter smaller than the top of the crest and a diameter smaller than the bottom of the valley. Since there is a large step, the clearance is small, and therefore, the screw cap is guided by the step and is easily and properly screwed into a predetermined position.
しかして、本考案における注出具にあつては、
ネジ蓋または注出口の材質はポリエチレン、ポリ
プロピレン、ポリ塩化ビニルまたはポリエステル
等のプラスチツク、ガラス或いはアルミ、鉄等の
金属など何れでも良い。 However, regarding the pouring tool in the present invention,
The screw cap or spout may be made of any material such as plastic such as polyethylene, polypropylene, polyvinyl chloride, or polyester, glass, or metal such as aluminum or iron.
また、段差部の寸法は、ネジ蓋または注出口の
口径の寸法により適宜変更できるが、通常のネジ
蓋又は注出口の口径は5.0〜150mm程度であり、こ
のような場合、段差部の寸法は、ネジ山の頂より
約1.0〜15mm程度低く、また、その幅は約1.0〜30
mm程度である。 In addition, the dimensions of the step part can be changed as appropriate depending on the diameter of the screw cap or spout, but the diameter of the normal screw cap or spout is about 5.0 to 150 mm, and in such cases, the dimensions of the step part are , about 1.0 to 15 mm lower than the top of the screw thread, and its width is about 1.0 to 30 mm.
It is about mm.

防止の効果がない。 In this invention, if the dimension of the stepped part is 1.0 mm or less from the top of the screw thread, the clearance may be too small and the screw cap may not be tightened, or the screw cap may be automatically tightened by a machine. It may damage the pouring tool, or it may cause damage to the pouring tool.
If the stepped portion has a dimension of 15 mm or more, the clearance will be too large and will not be different from the conventional one, and will not be effective in preventing diagonal tightening.
更に、本考案の段差部が先端に向かつて斜め状

である。<Effects of the invention> As mentioned above, the present invention is formed by forming a step part at the outermost end of the thread on either the screw cap or the spout, which is approximately 1.0 to 15 mm lower depending on the height of the thread. When the screw caps are rotated and screwed together, even if the screw caps are initially fitted diagonally, the existence of the stepped portion allows the screw caps to return to their normal positions along the stepped portions, making it easy to prevent diagonal tightening. It is effective.
