Description

本発明は、容器のキャッピング時に、キャップが挿入し易く、不適切なキャップの螺合を防止した容器に関する。 The present invention relates to a container in which a cap can be easily inserted when the container is capped, and improper screwing of the cap is prevented.

従来、チューブ容器又はボトル容器等の容器口部の雄ねじには、キャップの雌ねじが螺合され、容器口部が閉鎖されている。図４及び図５は、従来のチューブ容器又はボトル容器等の容器を示す図面であり、容器５０の口部５１には雄ねじ５２が形成されている。一方キャップ５６の内周面には、雌ねじ５７が形成されている。従来の容器５０のキャップ挿入部５３と、口部５１の雄ねじ５２の寸法差を以下の実施例に示す。例えば従来、容器５０の雄ねじ５２の山径Ｘが１４．０ｍｍ、谷径Ｙが１２．９６ｍｍ、キャップ挿入部５３の外径Ｚが１２．０ｍｍ
である容器２０がある場合、山径Ｘと谷径Ｙの寸法差Ｗは半径で、０．５２ｍｍであり、したがって、雄ねじ５２の谷部５４の谷径Ｙと、キャップ挿入部５３の外径Ｚの寸法差Ｔは、半径で０．４８ｍｍである。よって、従来の図５に示す実施例に係る容器の場合、Ｔは０．５ｍｍ±０．０２ｍｍの範囲、すなわち０．４８ｍｍ〜０．５２ｍｍの範囲にあることになり、寸法Ｔは極めて大きい。 Conventionally, a female screw of a cap is screwed into a male screw of a container mouth such as a tube container or a bottle container, and the container mouth is closed. 4 and 5 are views showing a conventional container such as a tube container or a bottle container, and a male screw 52 is formed at the mouth 51 of the container 50. On the other hand, an internal thread 57 is formed on the inner peripheral surface of the cap 56. The dimensional difference between the cap insertion part 53 of the conventional container 50 and the male screw 52 of the mouth part 51 is shown in the following examples. For example, conventionally, the thread diameter X of the male thread 52 of the container 50 is 14.0 mm, the valley diameter Y is 12.96 mm, and the outer diameter Z of the cap insertion portion 53 is 12.0 mm.
, The dimensional difference W between the crest diameter X and the trough diameter Y is 0.52 mm in radius. Therefore, the trough diameter Y of the trough portion 54 of the male screw 52 and the outer diameter of the cap insertion portion 53 are as follows. The dimensional difference T of Z is 0.48 mm in radius. Therefore, in the case of the container according to the conventional example shown in FIG. 5, T is in the range of 0.5 mm ± 0.02 mm, that is, in the range of 0.48 mm to 0.52 mm, and the dimension T is extremely large.

このように寸法Ｔを大きくする主な理由として、雄ねじ５２の成形の際に、ねじ切り用の転造駒が、キャップ挿入部５３の外縁に接触し、キャップ挿入部５３に傷がつくのを防止するため、谷径Ｙとキャップ挿入部５３の外径Ｚの寸法Ｔをできるだけ大きくする必要がある。しかし、この寸法Ｔが大きい場合、図４に示すように、キャップ５６の螺合時に、キャップ５６の雌ねじ５７の山部及び谷部が、雄ねじ５２の山部と谷部に、スムーズに係合しないため、図４に示すように、キャップ５６がどちらかに、傾いてキャップ挿入部５３に挿入されるという問題があった。そして、特にキャッピングを急いでいる場合、不適切な螺合になるという問題があった。従来の口部とキャップの螺合形態のチューブ容器として、例えば、特許文献１がある（特許文献１参照）。
実開昭６１−８０２４０号 The main reason for increasing the dimension T in this way is to prevent the threaded rolling piece from coming into contact with the outer edge of the cap insertion portion 53 and scratching the cap insertion portion 53 when the male screw 52 is formed. Therefore, it is necessary to make the dimension T of the valley diameter Y and the outer diameter Z of the cap insertion portion 53 as large as possible. However, when the dimension T is large, as shown in FIG. 4, when the cap 56 is screwed, the crests and troughs of the female screw 57 of the cap 56 are smoothly engaged with the crests and troughs of the male screw 52. Therefore, as shown in FIG. 4, there is a problem that the cap 56 is inclined and inserted into the cap insertion portion 53. In particular, when capping is rushed, there is a problem of inappropriate screwing. As a conventional tube container in a screwed form of a mouth and a cap, for example, there is Patent Document 1 (see Patent Document 1).
Japanese Utility Model Sho 61-80240

この発明は、このような従来の課題に着目してなされたものであり、ねじ切り用の転造駒が、キャップ挿入部に接触せず、かつ容器のキャッピング時に、キャップが挿入し易く、不適切なキャップの螺合を防止した、適切な寸法の容器を提供することを目的とする。 The present invention has been made paying attention to such a conventional problem. The rolling piece for threading does not come into contact with the cap insertion portion, and the cap is easy to insert when the container is capped. An object of the present invention is to provide a container of an appropriate size that prevents screwing of a cap.

この課題を解決するため、請求項１記載の発明の解決手段は、容器口部の雄ねじ部の谷径寸法（ｂ）と、容器口部のキャップ挿入部の外径寸法（ｃ）との差（ｄ）を、半径で０．１〜０．４ｍｍに構成したことを特徴とする容器である。
雄ねじの谷部と、キャップ挿入部の外径の寸法差を０．１ｍｍ以上、０．４ｍｍ以下に構成することで、キャップが頗る挿入し易く、不適切なキャップの螺合を防止できる。 In order to solve this problem, the solution means of the invention described in claim 1 is the difference between the valley diameter dimension (b) of the male threaded portion of the container mouth portion and the outer diameter dimension (c) of the cap insertion portion of the container mouth portion. (D) is a container having a radius of 0.1 to 0.4 mm.
By configuring the dimensional difference between the external thread trough portion and the outer diameter of the cap insertion portion to be 0.1 mm or more and 0.4 mm or less, it is easy to insert the cap, and inappropriate cap screwing can be prevented.

請求項２記載の発明の解決手段は、容器が、チューブ容器又はボトル容器であることを特徴とする容器である。 According to a second aspect of the invention, the container is a tube container or a bottle container.

本発明によれば、キャップ挿入部の外径と、雄ねじの谷部の谷径との寸法差が小さいので、容器のキャッピング時に、キャップが挿入し易く、
キャップが左右のどちらかに傾いて、キャップ挿入部に挿入されるのを防止でき、不適切なキャップの螺合を防止できる効果を有する。 According to the present invention, since the dimensional difference between the outer diameter of the cap insertion portion and the valley diameter of the valley portion of the male screw is small, the cap can be easily inserted when capping the container,
It is possible to prevent the cap from being tilted to the left or right and being inserted into the cap insertion portion, thereby preventing an inappropriate screwing of the cap.

本発明の実施例を、図面に基づいて説明する。 Embodiments of the present invention will be described with reference to the drawings.

図１及び図３は、本発明の実施例１を示す図面である。図１において、１はチューブ容器であり、チューブ容器１の口部２には、雄ねじ３が形成され、この雄ねじ３の上部には、キャップ挿入部４が形成されている。一方キャップ７の内周面には、雌ねじ８が形成されている。図３において、雄ねじ３の山部６の山径をａ、雄ねじ３の谷部５の谷径をｂ、キャップ挿入部４の外径をｃで表わすと共に、容器１のキャップ挿入部４の外径ｃと、雄ねじ３の谷部５の谷径ｂとの寸法差を、半径でｄで表わすと、実施例１は、ｄが０．１ｍｍ以上、０．４ｍｍ以下の範囲で構成されており、好ましくは０．２〜０．３ｍｍに構成されている。 1 and 3 are drawings showing Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes a tube container. A male screw 3 is formed in the mouth portion 2 of the tube container 1, and a cap insertion portion 4 is formed in the upper part of the male screw 3. On the other hand, a female screw 8 is formed on the inner peripheral surface of the cap 7. In FIG. 3, the crest diameter of the crest 6 of the male screw 3 is represented by a, the crevice of the trough 5 of the male screw 3 is represented by b, the outer diameter of the cap insertion section 4 is represented by c, and the outside of the cap insertion section 4 of the container 1. When the dimensional difference between the diameter c and the valley diameter b of the valley portion 5 of the male screw 3 is expressed by a radius d, Example 1 is configured in a range where d is 0.1 mm or more and 0.4 mm or less. , Preferably 0.2 to 0.3 mm.

そして、本発明の実施例１の具体的寸法として、例えば、雄ねじ３の山部６の山径ａが１４．０ｍｍ、谷部５の谷径ｂが１２．９６ｍｍ，キャップ挿入部４の外径ｃが１２．５６ｍｍであり、ｅが０．５２ｍｍである。この実施例１の容器１の場合、キャップ挿入部４の外径ｃと、雄ねじ３の谷部５の谷径ｂとの寸法ｄは、半径で０．２ｍｍであり寸法ｄは、従来に比べて小さい。 As specific dimensions of the first embodiment of the present invention, for example, the crest diameter 6 of the crest 6 of the male screw 3 is 14.0 mm, the crevice b of the trough 5 is 12.96 mm, and the outer diameter of the cap insertion section 4 c is 12.56 mm, and e is 0.52 mm. In the case of the container 1 of the first embodiment, the dimension d between the outer diameter c of the cap insertion portion 4 and the valley diameter b of the valley portion 5 of the male screw 3 is 0.2 mm in radius, and the dimension d is smaller than that of the conventional case. Small.

図２は、本発明の実施例２を示す図面である。図２において、１１はボトル容器である。口部１２におけるキャップ挿入部１４の外径、雄ねじ１３の山部における山径、雄ねじ１３の谷部における谷径は、実施例１と同様に形成されている。 FIG. 2 is a drawing showing Example 2 of the present invention. In FIG. 2, 11 is a bottle container. The outer diameter of the cap insertion portion 14 in the mouth portion 12, the crest diameter at the crest portion of the male screw 13, and the trough diameter at the trough portion of the male screw 13 are formed in the same manner as in the first embodiment.

本発明に係る容器の口部先端と雄ねじの構造は、チューブ容器のみならず、ボトル容器にも適用できる。そして、容器のキャッピング時に、キャップが挿入し易いので、キャッピングを急いでいる時、特に子供、老人等であっても、キャップが口部の雄ねじにスムーズにかかり、キャッピングが容易である。したがって、不適切な螺合を防止できる。本発明は、チューブ容器、ボトル容器のねじ部に適用でき、医薬品、食品、化粧品等を収納する日用品の容器として広く適し、多岐にわたって利用することができる。 The structure of the mouth end and the male screw of the container according to the present invention can be applied not only to a tube container but also to a bottle container. Since the cap can be easily inserted when capping the container, the cap is smoothly applied to the male screw of the mouth portion even when rushing the capping, especially a child, an elderly person, etc., and capping is easy. Therefore, inappropriate screwing can be prevented. INDUSTRIAL APPLICABILITY The present invention can be applied to the threaded portion of tube containers and bottle containers, and is widely suitable as a daily necessities container for storing pharmaceuticals, foods, cosmetics, etc., and can be used in a wide variety of applications.
