Description

本発明は、蓋構造に関し、特に、閉蓋時は蓋体を容器本体に押し被せて嵌合し、開蓋時は蓋体を回転させることにより嵌合を解除する蓋構造に関するものである。 The present invention relates to a lid structure, and more particularly to a lid structure that presses and fits a lid body onto a container body when the lid is closed and releases the fitting by rotating the lid body when the lid is opened.

従来、閉蓋時は蓋体を容器本体に押し被せて嵌合し、開蓋時は蓋体を回転させることにより嵌合を解除する蓋構造は、例えば、下記の特許文献１に開示されている。
この蓋構造は、蓋体及び容器本体に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条と、開蓋時の回転により相互に摺接して蓋体を押し上げるガイド片とを設けている。 Conventionally, a lid structure that presses and fits the lid body onto the container body when the lid is closed and releases the fitting by rotating the lid body when the lid is opened is disclosed in, for example, Patent Document 1 below. Yes.
This lid structure is provided with protrusions that can be fitted over the lid body and the container body by being pushed in when the lid is closed, and guide pieces that are slidably brought into contact with each other by the rotation at the time of opening the lid and push up the lid body. Yes.

しかしながら、上記従来の蓋構造は、容器本体側の突条が連続するリング状であるため、開蓋時に蓋体の突条が通過しにくく、嵌合強度のコントロールがしにくいという問題を有している。
また、蓋体の突条が容器本体の突条を乗り越えるためには、蓋体の周壁が拡径されなければならないが、蓋体の周壁は、ガイド片が一体に形成されて肉厚となっており拡径しにくくなっている。
なお、これに対処すべく突条同士の嵌合を弱くすると、ガイド片の作用に関係なく、意図しない時に開蓋される事故が起きやすい。 However, the conventional lid structure has a ring shape in which the ridges on the container body side are continuous, so that the ridges of the lid body are difficult to pass when the lid is opened, and it is difficult to control the fitting strength. ing.
In addition, in order for the ridge of the lid to get over the ridge of the container body, the peripheral wall of the lid must be enlarged in diameter, but the peripheral wall of the lid is thickened by integrally forming guide pieces. It is difficult to expand the diameter.
If the fitting between the protrusions is weakened to cope with this, an accident that the lid is opened unintentionally easily occurs regardless of the action of the guide piece.

本発明は、上記従来の蓋構造が有する問題点に鑑み、閉蓋状態では突条同士が嵌合を強固に保持するとともに、開蓋時には比較的小さな力で開けることができる蓋構造を提供することを目的とする。 In view of the problems of the above-described conventional lid structure, the present invention provides a lid structure in which the protrusions firmly hold the fitting in the closed state and can be opened with a relatively small force when the lid is opened. For the purpose.

上記目的を達成するため、本第１発明の蓋構造は、蓋体及び容器本体に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条と、開蓋時の回転により相互に摺接して蓋体を押し上げるガイド片とを設けた蓋構造において、蓋体及び容器本体の突条の、前記押し上げにより相手側の突条が通過する部位に、突条がない空隙部又は他の部分より高さが低い突条からなる低山部をそれぞれ設けたことを特徴とする。 In order to achieve the above object, the lid structure of the first aspect of the present invention is in sliding contact with the lid and the container main body by means of a protrusion that gets over and fits with each other by pushing when the lid is closed, and by rotation when the lid is opened. In the lid structure provided with the guide piece that pushes up the lid, the gap of the lid and the container main body from the gap or other part where there is no ridge in the part through which the opposite ridge passes by the push-up The present invention is characterized in that low mountain portions each having a low ridge are provided.

また、同じ目的を達成するため、本第２発明の蓋構造は、蓋体及び容器本体に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条と、開蓋時の回転により相互に摺接して蓋体を押し上げるガイド片とを設けた蓋構造において、蓋体の周壁を内外の２重壁に設け、内側の周壁により、前記突条を形成する舌片とガイド片とを各々独立して形成したことを特徴とする。 In order to achieve the same object, the lid structure of the second aspect of the present invention is configured such that the protrusions that are fitted over the lid body and the container body by pushing in when the lid is closed, and the rotation when the lid is opened. In a lid structure provided with a guide piece that slides and pushes up the lid body, the peripheral wall of the lid body is provided on the inner and outer double walls, and the tongue piece and the guide piece that form the ridge are independent of each other by the inner peripheral wall. It is characterized by having formed.

本第１発明の蓋構造によれば、蓋体及び容器本体に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条と、開蓋時の回転により相互に摺接して蓋体を押し上げるガイド片とを設けた蓋構造において、蓋体及び容器本体の突条の、前記押し上げにより相手側の突条が通過する部位に、突条がない空隙部又は他の部分より高さが低い突条からなる低山部をそれぞれ設けることから、蓋体を回転させてガイド片により蓋体を押し上げた際に、蓋体と容器本体の突条が相手側の空隙部又は低山部を通過することができ、これにより、突条の乗り越え時の抵抗を弱めて、蓋体を比較的小さな力で開けることができる。
そして、閉蓋状態においては、ガイド片同士が干渉することから、蓋体と容器本体の突条は相手側の空隙部又は低山部の位置に移動することができず、これにより、突条同士が嵌合を強固に保持し、不用意な開蓋を防止することができる。 According to the lid structure of the first aspect of the present invention, the ridges that are fitted over the lid body and the container main body by being pushed in when the lid is closed, and the lid body is slidably brought into contact with each other by the rotation at the time of opening the lid body. In a lid structure provided with a guide piece, a protrusion having a height lower than that of the gap or other part where there is no protrusion at the part of the protrusion of the cover and the container body through which the protrusion on the other side passes by the push-up. Since each of the low ridges is provided with a strip, when the lid is rotated and the lid is pushed up by the guide piece, the protrusion of the lid and the container body passes through the gap or low ridge on the other side. This makes it possible to weaken the resistance at the time of overcoming the ridge and open the lid with a relatively small force.
In the closed state, since the guide pieces interfere with each other, the ridges of the lid body and the container body cannot move to the position of the gap portion or the low mountain portion on the other side. The members firmly hold the fitting, and an inadvertent opening can be prevented.

また、本第２発明の蓋構造によれば、蓋体及び容器本体に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条と、開蓋時の回転により相互に摺接して蓋体を押し上げるガイド片とを設けた蓋構造において、蓋体の周壁を内外の２重壁に設け、内側の周壁により、前記突条を形成する舌片とガイド片とを各々独立して形成することから、突条を形成した舌片が、ガイド片の存在やガイド片同士の摺接に関わりなく容易に拡径することができ、これにより、突条の乗り越え時の抵抗を弱めて、蓋体を比較的小さな力で開閉することができる。
そして、閉蓋状態においては、突条同士が嵌合を強固に保持することから、不用意な開蓋を防止することができる。 Further, according to the lid structure of the second invention, the ridges that are fitted over the lid body and the container main body by being pushed in when the lid is closed, and are slidably contacted with each other by the rotation when the lid is opened. In the lid structure provided with a guide piece for pushing up, the peripheral wall of the lid body is provided on the inner and outer double walls, and the tongue piece and the guide piece forming the protrusion are independently formed by the inner peripheral wall. Therefore, the tongue that forms the ridge can easily expand its diameter regardless of the presence of the guide piece or the sliding contact between the guide pieces, thereby reducing the resistance when the ridge is over the lid, Can be opened and closed with a relatively small force.
And in a closed state, since protrusions hold | maintain fitting firmly, inadvertent opening can be prevented.

以下、本発明の蓋構造の実施の形態を図面に基づいて説明する。 Hereinafter, embodiments of the lid structure of the present invention will be described with reference to the drawings.

図１〜図２に、本発明の蓋構造の一実施例を示す。
この蓋構造は、蓋体１及び容器本体２に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条１１、２１と、開蓋時の回転により相互に摺接して蓋体１を押し上げるガイド片１２、２２とを設けている。
そして、かかる蓋構造において、蓋体１及び容器本体２の突条１１、２１の、前記押し上げにより相手側の突条２１、１１が通過する部位に、突条がない空隙部１３、２３をそれぞれ設けている。
この場合、空隙部１３、２３に代えて、他の部分より高さが低い突条からなる低山部（図示省略）を形成することも可能である。 1 to 2 show an embodiment of the lid structure of the present invention.
In this lid structure, the ridges 11 and 21 that are fitted over the lid body 1 and the container main body 2 by being pushed in when the lid is closed, and the lid body 1 are slidably brought into contact with each other by the rotation when the lid is opened, and the lid body 1 is pushed up. Guide pieces 12 and 22 are provided.
In such a lid structure, the gaps 13 and 23 having no protrusions are respectively formed in the portions of the protrusions 11 and 21 of the cover body 1 and the container main body 2 through which the protrusions 21 and 11 on the other side pass by the push-up. Provided.
In this case, instead of the gaps 13 and 23, it is also possible to form a low mountain portion (not shown) made of a protrusion having a lower height than the other portions.

蓋体１は、可撓性の合成樹脂を主材とした円形のものからなり、その周壁１ａ、１ｂを内外の２重壁に設け、内側の周壁１ｂにより、突条１１が形成される舌片１４とガイド片１２とを各々独立して形成している。
突条１１は、断続する舌片１４の内側に円周方向に形成されており、この突条１１と舌片１４は、本実施例では、円周上に等間隔で６箇所設けられている。
ガイド片１２は、容器本体側のガイド片２２と摺接する傾斜面を備えた略三角形を呈し、本実施例では、円周上に等間隔で６箇所設けられている。 The lid body 1 is made of a circular material mainly composed of a flexible synthetic resin, and its peripheral walls 1a and 1b are provided on inner and outer double walls, and the tongue 11 on which the protrusion 11 is formed by the inner peripheral wall 1b. The piece 14 and the guide piece 12 are formed independently of each other.
The protrusion 11 is formed in the circumferential direction inside the intermittent tongue piece 14, and in this embodiment, the protrusion 11 and the tongue piece 14 are provided at six locations on the circumference at equal intervals. .
The guide piece 12 has a substantially triangular shape having an inclined surface that is in sliding contact with the guide piece 22 on the container body side, and in this embodiment, six pieces are provided at equal intervals on the circumference.

容器本体２は、合成樹脂を主材とした円形のカップからなり、蓋体１の内側の周壁１ｂが被嵌する短円筒状の口部２ａを備えている。
突条２１は、口部２ａの周壁の外側に円周方向に断続して形成されており、本実施例では、等間隔で６箇所設けられている。
ガイド片２２は、蓋体側のガイド片１２と摺接する傾斜面を備えた略三角形を呈し、本実施例では、口部２ａの周囲に等間隔で６箇所設けられている。
また、このガイド片２２の傾斜面を隣接するガイド片２２まで延長し、閉蓋時に、蓋体側のガイド片１２をこの傾斜面の終端位置まで案内することにより、蓋体側のガイド片１２の位置決めを行い、例えば、多角形状容器の蓋体と容器本体の位置合わせを行うことができる。 The container body 2 is formed of a circular cup mainly made of a synthetic resin, and includes a short cylindrical mouth portion 2a into which the inner peripheral wall 1b of the lid body 1 is fitted.
The ridges 21 are formed intermittently in the circumferential direction on the outer side of the peripheral wall of the mouth portion 2a. In this embodiment, six ridges 21 are provided at equal intervals.
The guide piece 22 has a substantially triangular shape having an inclined surface that is in sliding contact with the guide piece 12 on the lid side, and is provided at six locations around the mouth portion 2a at equal intervals in this embodiment.
Further, the inclined surface of the guide piece 22 is extended to the adjacent guide piece 22, and when the lid is closed, the guide piece 12 on the lid side is guided to the end position of the inclined surface, thereby positioning the guide piece 12 on the lid side. For example, the lid of the polygonal container and the container main body can be aligned.

なお、本実施例では、容器本体２と蓋体１の間には中蓋３が挿入されているが、発明を構成する上で必ずしも必要なものではないため、図１においてのみ表示している。 In the present embodiment, the inner lid 3 is inserted between the container main body 2 and the lid body 1, but is not necessarily required for configuring the invention, and is shown only in FIG. 1. .

次に、本実施例の蓋構造の動作を説明する。
本実施例の蓋構造は、閉蓋時は蓋体１を容器本体２に押し被せて嵌合し、開蓋時は蓋体１を所定角度回転させることにより嵌合を解除することができる。
具体的には、蓋体１を容器本体２に被せて押し込むと、舌片１４の弾性変形により、蓋体の突条１１と容器本体の突条２１とが相互に乗り越えて嵌合し、図２（ａ）に示すように、閉蓋される。
この閉蓋状態で蓋体１を回転させても、図中１点鎖線で示すように、蓋体のガイド片１２と容器本体のガイド片２２とが干渉するため、蓋体１の突条１１と容器本体２の突条２１は互いに重なる範囲にとどまり、蓋体１は容易には離脱しない。
そして、これをより確実にするために、突条１１、２１の形状を、係合方向の傾斜面をなだらかに（傾斜面の傾斜角を、例えば、３０゜程度に）、離脱方向の傾斜面を急勾配に（傾斜面の傾斜角を、例えば、７０゜程度に）、それぞれ形成することが好ましい。 Next, the operation of the lid structure of this embodiment will be described.
The lid structure of the present embodiment can be fitted by pressing the lid 1 against the container body 2 when the lid is closed, and can be released by rotating the lid 1 by a predetermined angle when the lid is opened.
Specifically, when the lid 1 is pushed over the container main body 2, the protrusion 11 of the lid and the protrusion 21 of the container main body get over each other due to the elastic deformation of the tongue piece 14. As shown in 2 (a), the lid is closed.
Even when the lid 1 is rotated in this closed state, the guide piece 12 of the lid and the guide piece 22 of the container main body interfere with each other as shown by a one-dot chain line in the figure. And the protrusion 21 of the container main body 2 stays in a range where they overlap each other, and the lid body 1 is not easily detached.
And in order to make this more reliable, the shape of the ridges 11 and 21 is made such that the inclined surface in the engaging direction is gentle (the inclined angle of the inclined surface is, for example, about 30 °), and the inclined surface in the separating direction. Are preferably formed so as to be steep (the inclination angle of the inclined surface is, for example, about 70 °).

一方、開蓋時は、図２（ａ）〜（ｂ）に示すように、ガイド片１２とガイド片２２が当接する位置から、ガイド片１２を弾性変形させながら蓋体１をさらに回転させることにより、蓋体１を押し上げながら、蓋体１と容器本体２の突条１１、１２を相手側の空隙部１３、２３に移動させて通過させる。
これにより、突条１１、２１の乗り越え時の抵抗を弱め、蓋体１を比較的小さな力で開けることができる。 On the other hand, when the lid is opened, as shown in FIGS. 2A and 2B, the lid 1 is further rotated from the position where the guide piece 12 and the guide piece 22 abut while elastically deforming the guide piece 12. Thus, while pushing up the lid body 1, the ridges 11 and 12 of the lid body 1 and the container body 2 are moved and passed through the gap portions 13 and 23 on the other side.
Thereby, the resistance at the time of getting over the ridges 11 and 21 can be weakened, and the lid 1 can be opened with a relatively small force.

かくして、本実施例の蓋構造は、蓋体１及び容器本体２に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条１１、２１と、開蓋時の回転により相互に摺接して蓋体１を押し上げるガイド片１２、２２とを設けた蓋構造において、蓋体１及び容器本体２の突条１１、２１の、前記押し上げにより相手側の突条が通過する部位に、突条がない空隙部１３、２３を設けることから、蓋体１を回転させてガイド片１２、２２により蓋体１を押し上げた際に、蓋体１と容器本体２の突条１１、２１が相手側の空隙部１３、２３を通過することができ、これにより、突条１１、２１の乗り越え時の抵抗を弱めて、蓋体１を比較的小さな力で開けることができる。
そして、閉蓋状態においては、ガイド片１２、２２同士が干渉することから、蓋体１と容器本体２の突条１１、２１は相手側の空隙部又は低山部の位置に移動することができず、これにより、突条１１、２１同士が嵌合を強固に保持し、不用意な開蓋を防止することができる。 Thus, the lid structure of the present embodiment is in sliding contact with the lid 1 and the container body 2 by the protrusions 11 and 21 that are fitted over each other by pressing when the lid is closed, and by the rotation when the lid is opened. In the lid structure provided with the guide pieces 12 and 22 for pushing up the lid 1, there is a ridge at the portion of the ridges 11 and 21 of the lid 1 and the container body 2 through which the opposite ridge passes. Since the gap portions 13 and 23 are not provided, when the lid body 1 is rotated and the lid body 1 is pushed up by the guide pieces 12 and 22, the protrusions 11 and 21 of the lid body 1 and the container body 2 are opposite to each other. The gaps 13 and 23 can be passed through, thereby reducing the resistance when the protrusions 11 and 21 get over, and the lid 1 can be opened with a relatively small force.
In the closed state, the guide pieces 12 and 22 interfere with each other, so that the ridges 11 and 21 of the lid body 1 and the container body 2 can move to the position of the other-side gap portion or low mountain portion. In this way, the protrusions 11 and 21 can hold the fitting firmly and prevent inadvertent opening.

また、本実施例の蓋構造は、蓋体１及び容器本体２に、閉蓋時の押し込みにより相互に乗り越えて嵌合する突条１１、２１と、開蓋時の回転により相互に摺接して蓋体１を押し上げるガイド片１２、２２とを設けた蓋構造において、蓋体１の周壁１ａ、１ｂを内外の２重壁に設け、内側の周壁１ｂにより、前記突条１１を形成する舌片１４とガイド片１２とを各々独立して形成することから、突条１１を形成した舌片１４が、ガイド片１２の存在やガイド片１２、２２同士の摺接に関わりなく容易に拡径することができ、これにより、突条１１、２１の乗り越え時の抵抗を弱めて、蓋体１を比較的小さな力で開閉することができる。
そして、閉蓋状態においては、突条１１、２１同士が嵌合を強固に保持することから、不用意な開蓋を防止することができる。 Further, the lid structure of this embodiment is in sliding contact with the lid body 1 and the container body 2 by the protrusions 11 and 21 which are fitted over each other by pressing when the lid is closed, and by rotation when the lid is opened. In the lid structure provided with the guide pieces 12 and 22 for pushing up the lid body 1, the peripheral walls 1a and 1b of the lid body 1 are provided on the inner and outer double walls, and the tongue 11 is formed by the inner peripheral wall 1b. 14 and the guide piece 12 are formed independently of each other, so that the tongue piece 14 on which the protrusion 11 is formed easily expands regardless of the presence of the guide piece 12 and the sliding contact between the guide pieces 12 and 22. Accordingly, the resistance when the ridges 11 and 21 are moved over is weakened, and the lid 1 can be opened and closed with a relatively small force.
And in a closed state, since the protrusions 11 and 21 hold | maintain fitting firmly, inadvertent opening can be prevented.

以上、本発明の蓋構造について、実施例に基づいて説明したが、本発明は上記実施例に記載した構成に限定されるものではなく、その趣旨を逸脱しない範囲において適宜構成を変更することができる。
例えば、容器本体側の突条やガイド片は、容器に取り付けるような別体に設けた口部に形成することも可能である。 The lid structure of the present invention has been described based on the embodiments. However, the present invention is not limited to the configurations described in the above embodiments, and the configurations can be changed as appropriate without departing from the spirit of the present invention. it can.
For example, the protrusion or guide piece on the container body side can be formed in a mouth provided in a separate body attached to the container.

本発明の蓋構造は、閉蓋状態では突条同士が嵌合を強固に保持するとともに、開蓋時には比較的小さな力で開けることができるという特性を有していることから、例えば、合成樹脂容器、ビン、チューブ等の容器の蓋構造として好適に用いることができる。 The lid structure of the present invention has characteristics that the protrusions firmly hold the fitting in the closed state and can be opened with a relatively small force when the lid is opened. It can be suitably used as a lid structure for containers such as containers, bottles and tubes.
