Description

本発明は、容器本体に着脱可能に取り付けられ容器本体の開口部を開閉する容器用蓋材および容器に関する。   The present invention relates to a container lid member and a container that are detachably attached to a container body and open and close an opening of the container body.

粘性を有する調味料、あるいは惣菜や調理食材など、食品や食材を収容する容器として、用途に応じて各種形状のプラスチック容器が利用されている。これらプラスチック容器において、蓋材の周縁を弾性変形することで、容器本体の上面開口部の外周部に係脱し、上面開口部を開閉する構成が採られている（例えば、特許文献１〜３参照）。
これら特許文献１〜３に記載の従来の容器では、容器本体の外周部に係脱可能に係合して上面開口部を閉塞する係合部を有した蓋材を備えている。蓋材の係合部は、蓋材の最外周縁に設けられ容器本体の外周縁に係脱する係脱面部と、当該係脱面部に連続するとともに蓋材の天面部分に連続して設けられ、容器本体の開口部の外周縁の上面に面で当接する当接面部とから構成されている。 Various types of plastic containers are used as containers for containing foods and foodstuffs such as viscous seasonings, side dishes and cooked foodstuffs.

ところで、プラスチック容器では、軽量化や材料コストの低減を目的として、薄肉化が検討されている。しかしながら、薄肉化により容器の剛性が損なわれ、蓋材に外力が作用した際に蓋材が弾性変形し、割れなどの損傷を生じたり、容器本体から外れてしまい、内容物が漏れ出るなどの不都合が生じたりするおそれがある。また、蓋材を容器本体に取り付ける際の押圧力により、蓋材が弾性変形して容器本体に適切に係合できず、蓋材を取り付ける作業が煩雑となるおそれもある。   By the way, thinning of the plastic container is being studied for the purpose of reducing the weight and reducing the material cost. However, the rigidity of the container is lost due to thinning, and when the external force is applied to the cover material, the cover material is elastically deformed, causing damage such as cracking, or coming off from the container body, and the contents leak out. Inconvenience may occur. Further, due to the pressing force when the lid member is attached to the container body, the lid member is elastically deformed and cannot be properly engaged with the container body, and the work of attaching the lid member may become complicated.

本発明の目的は、外力を吸収して損傷を抑制できるとともに、容器本体に容易で確実に着脱できる容器用蓋材および容器を提供することにある。   An object of the present invention is to provide a container lid and a container that can absorb external force and suppress damage and can be easily and reliably attached to and detached from the container body.

本発明の容器用蓋材は、鉛直方向の上面に開口部を有した容器本体に着脱可能に取り付けられ前記開口部を開閉する容器用蓋材であって、前記容器本体の開口部の外周側に外周方向から係脱可能な係脱部と、前記開口部を覆う天面部と、前記係脱部および前記天面部の間に設けられた段差部とを備え、前記段差部は、前記係脱部から延設され鉛直方向に対して交差する平面を有する第一段差部と、鉛直方向に対して交差する平面を有し前記第一段差部に対して段差状に設けられた第二段差部とを備え、前記係脱部から前記天面部に渡る方向の前記第二段差部の幅寸法が、前記第一段差部の幅寸法より幅広であることを特徴とする。   The container lid of the present invention is a container lid that is detachably attached to a container main body having an opening on the upper surface in the vertical direction and opens and closes the opening, and is on the outer peripheral side of the opening of the container main body An engagement / disengagement portion that can be engaged / disengaged from the outer peripheral direction, a top surface portion that covers the opening, and a step portion provided between the engagement / disengagement portion and the top surface portion. A first step portion having a plane extending from the portion and intersecting the vertical direction, and a second step portion having a plane intersecting the vertical direction and provided in a step shape with respect to the first step portion. And the width dimension of the second stepped portion in the direction from the engagement / disengagement portion to the top surface portion is wider than the width dimension of the first stepped portion.

この発明では、当該容器用蓋材を潰す方向に外力が加わった場合、天面部とともに第二段差部および当該第二段差部と天面部との連結部分で他の部位に比して大きく弾性変形して外力を吸収するので、当該容器用蓋材の損傷を抑制できる。さらに、第一段差部および第一段差部と係脱部との連結部分での弾性変形は小さく剛性が高いので、第二段差部および当該第二段差部と天面部との連結部分で大きく弾性変形しても、係脱部が容器本体の開口部の外周側から離間する方向に弾性変形することが抑制され、係脱部と容器本体との係合が解除されることを抑制して当該容器用蓋材が外れてしまう不都合を抑制できる。また、当該容器用蓋材に押圧力を作用して容器本体に取り付ける際、第一段差部近傍の剛性により、係脱部が容器本体の開口部の外周側から離間する方向に弾性変形することが抑制されるので、開口部の外周側に係脱する係脱部に押圧力が有効に作用し、当該容器用蓋材の良好な取付感が得られる。
このように、第一段差部と第二段差部とを第二段差部が幅広となる条件で多段に設ける簡単な構成で、損傷を抑制でき、係脱部が不用意に外れてしまうことを防止できるとともに、押圧力を作用する簡単な動作で容器本体に容易で確実に取り付けできることから、当該容器用蓋材を肉薄に形成することも容易にでき、軽量化や材料コストの低減も容易に図れる。 In this invention, when an external force is applied in the direction of crushing the container lid, the second step portion and the connecting portion between the second step portion and the top surface portion together with the top surface portion are greatly elastically deformed compared to other parts. Since external force is absorbed, damage to the container lid can be suppressed. Further, since the elastic deformation at the connecting portion between the first step portion and the first step portion and the engagement / disengagement portion is small and the rigidity is high, the second step portion and the connecting portion between the second step portion and the top surface portion are greatly elastic. Even if it is deformed, the engagement / disengagement part is restrained from elastically deforming in the direction away from the outer peripheral side of the opening of the container body, and the engagement between the engagement / disengagement part and the container body is restrained from being released. The inconvenience that the container lid is removed can be suppressed. In addition, when attaching the container lid to the container body by applying a pressing force, the engagement / disengagement part is elastically deformed in a direction away from the outer peripheral side of the opening of the container body due to the rigidity in the vicinity of the first stepped part. Therefore, the pressing force effectively acts on the engagement / disengagement portion that engages / disengages on the outer peripheral side of the opening, and a good feeling of attachment of the container lid member is obtained.
In this way, with a simple configuration in which the first stepped portion and the second stepped portion are provided in multiple stages under the condition that the second stepped portion is wide, damage can be suppressed, and the engagement / disengagement portion is unintentionally detached. Since it can be easily and reliably attached to the container body with a simple operation that applies a pressing force, the container lid can be easily formed thin, and it is easy to reduce weight and reduce material costs. I can plan.

そして、本発明では、前記係脱部は、鉛直方向に略沿った平面を有した側壁部を有し、前記第一段差部は、前記側壁部に対して折曲形成され水平方向に略沿った平面を有した平板状に形成され、前記第二段差部は、水平方向に略沿った平面を有した平板状に形成されている構成とすることが好ましい。
この発明では、係脱部の側壁部に対して第一段差部および第二段差部が略直交する状態となり、当該容器用蓋材を潰す方向に作用する外力により、第一段差部に比して幅広の第二段差部が外力を吸収しやすい平面により大きく弾性変形することが容易に得られる。 And in this invention, the said engagement / disengagement part has a side wall part which has the plane substantially along the perpendicular direction, and the said 1st level | step-difference part is bend | folded with respect to the said side wall part, and follows a horizontal direction substantially It is preferable that the second step portion is formed in a flat plate shape having a plane substantially along the horizontal direction.
In this invention, the first step portion and the second step portion are substantially perpendicular to the side wall portion of the engagement / disengagement portion, and the external force acting in the direction of crushing the container lid member is compared with the first step portion. The wide second step portion can be easily elastically deformed by a plane that easily absorbs external force.

また、本発明では、第二段差部は、外周縁が前記第一段差部に連続し、内周縁が前記天面部に連続して設けられている構成とすることが好ましい。
この発明では、外力により当該容器用蓋材が損傷しないために第二段差部の幅寸法を大きく設計しても、第二段差部が当該容器用蓋材の全体に対して外周縁に位置する状態が得られ、外力に対する十分な弾性変形が得られる。 Moreover, in this invention, it is preferable that the 2nd level | step-difference part is set as the structure by which an outer periphery continues to the said 1st level | step difference part, and an inner periphery continues to the said top | upper surface part.
In this invention, even if the width of the second stepped portion is designed to be large because the container lid is not damaged by an external force, the second stepped portion is located on the outer peripheral edge with respect to the entire container lid. The state is obtained, and sufficient elastic deformation with respect to the external force is obtained.

そして、本発明では、前記第一段差部の幅寸法は、厚さ寸法に対して、２．５倍以下である構成とすることが好ましい。
この発明では、第一段差部の幅寸法が厚さ寸法に対して２．５倍以下であることから、第一段差部の近傍の剛性が他の部位より高くなり、外力が作用した際に、第一段差部およびその近傍ではほとんど弾性変形せずに第二段差部が変形することにより、当該容器用蓋材の外力による損傷をより防止できるとともに、容器本体とのより確実な係脱状態が得られる。 And in this invention, it is preferable to set it as the structure whose width dimension of said 1st level | step-difference part is 2.5 times or less with respect to thickness dimension.
In this invention, since the width dimension of the first stepped portion is 2.5 times or less than the thickness dimension, the rigidity in the vicinity of the first stepped portion becomes higher than other parts, and when an external force is applied. In addition, the second stepped portion is deformed almost without elastic deformation in the first stepped portion and the vicinity thereof, so that damage due to external force of the container lid can be further prevented, and a more reliable engagement / disengagement state with the container body Is obtained.

さらに、本発明では、前記天面部がドーム形状を有し、前記天面部における前記段差部に延設する外周縁の平面と前記第二段差部の平面とのなす角が、８５°以上９５°未満である構成とすることが好ましい。
この発明では、ドーム形状の天面部における段差部に延設する外周縁の平面と第二段差部の平面とのなす角が８５°以上９５°未満であることから、外力が作用した際に、天面部と段差部との連結部分の近傍で天面部と段差部とのなす角が小さくなる状態に変形し易く、外力に対してより弾性変形しやすくなり、当該容器用蓋材の外力による損傷をより防止できるとともに、容器本体とのより確実な係脱状態が得られる。
ここで、９５°以上に角度が大きくなると、天面部と段差部との連結部分の弾性変形が小さくなって効果が得られにくくなるおそれがあり、８５°より小さくなると、係脱に影響する寸法精度が得られやすい射出成形などの成形が極めて困難となるおそれがあるためである。 Further, in the present invention, the top surface portion has a dome shape, and an angle formed by an outer peripheral plane extending to the step portion on the top surface portion and a plane of the second step portion is 85 ° to 95 °. It is preferable to set it as the structure of less than.
In this invention, since the angle formed by the plane of the outer peripheral edge extending to the stepped portion in the dome-shaped top surface portion and the plane of the second stepped portion is 85 ° or more and less than 95 °, when an external force is applied, In the vicinity of the connecting portion between the top surface and the stepped portion, the angle formed between the top surface and the stepped portion is likely to be reduced, and it is more easily elastically deformed with respect to the external force. And a more reliable engagement / disengagement state with the container body.
Here, when the angle is increased to 95 ° or more, the elastic deformation of the connecting portion between the top surface portion and the stepped portion may be reduced, and it may be difficult to obtain the effect. This is because there is a possibility that molding such as injection molding that is easy to obtain accuracy may be extremely difficult.

また、本発明では、前記第二段差部の幅寸法は、前記第一段差部の幅寸法に対して２倍以上１０倍以下である構成とすることが好ましい。
この発明では、第二段差部の幅寸法が第一段差部の幅寸法に対して２倍以上１０倍以下であることから、第二段差部の弾性変形が十分に得られ、当該容器用蓋材の外力による損傷をより防止できるとともに、容器本体とのより確実な係脱状態が得られる。
ここで、２倍より幅狭になると、第二段差部の十分な弾性変形が得られず、外力を十分に吸収できなくなり、損傷するおそれがあるとともに、当該容器用蓋材の外周縁が外方に広がる弾性変形が大きくなって、容器本体との適切な係合状態が得られなくなるおそれがある。一方、１０倍より幅広になると、当該容器用蓋材を容器本体に取り付ける際の押圧力が係脱部に作用しにくくなり、良好な着脱感が得られにくくなるおそれがある。 In the present invention, it is preferable that the second stepped portion has a width dimension that is not less than 2 times and not more than 10 times the width dimension of the first stepped portion.
In this invention, since the width dimension of the second stepped portion is not less than 2 times and not more than 10 times the width dimension of the first stepped portion, sufficient elastic deformation of the second stepped portion can be obtained, and the container lid Damage from the external force of the material can be further prevented, and a more reliable engagement / disengagement state with the container body can be obtained.
Here, if the width is less than twice, sufficient elastic deformation of the second step portion cannot be obtained, the external force cannot be sufficiently absorbed, and there is a risk of damage, and the outer peripheral edge of the container lid member is outside. There is a possibility that the elastic deformation spreading toward the direction becomes large and an appropriate engagement state with the container body cannot be obtained. On the other hand, when it becomes wider than 10 times, the pressing force when the container lid is attached to the container main body is less likely to act on the engagement / disengagement part, and it may be difficult to obtain a good attachment / detachment feeling.

そして、本発明では、樹脂原料の射出成形により形成された構成とすることが好ましい。
この発明では、係脱部の係脱に寸法精度が要求される場合でも射出成形により精度よく成形できることから、外力により損傷せず、かつ寸法精度が要求される係脱部の係合が外れるなどの不都合を防止できる段差部を容易に形成できる。 And in this invention, it is preferable to set it as the structure formed by injection molding of the resin raw material.
In the present invention, even when dimensional accuracy is required for engagement / disengagement of the engagement / disengagement portion, the molding can be accurately performed by injection molding, so that the engagement / disengagement portion which is not damaged by external force and requires dimensional accuracy is disengaged. Can be easily formed.

また、本発明では、マーガリン用として構成することが好ましい。
この発明では、マーガリンは外部環境により液状化または固形化するので、マーガリンが漏れ出ることを防止するための寸法精度が必要で、かつ内容物のマーガリンを利用する毎に開口部の開閉動作が実施され、開閉動作毎に押圧力が良好に係脱部に作用して良好な開閉感を提供する必要があり、誤って落下して外力が作用しても損傷しない構成が必要である点で、特に有効である。 Moreover, in this invention, it is preferable to comprise for margarine.
In this invention, since the margarine is liquefied or solidified by the external environment, dimensional accuracy is required to prevent the margarine from leaking out, and the opening / closing operation is performed every time the contents of the margarine are used. It is necessary to provide a good opening / closing feeling by applying a good pressing force to the engagement / disengagement unit for each opening / closing operation, and it is necessary to have a configuration that does not damage even if an external force acts by dropping accidentally, It is particularly effective.

本発明の容器は、鉛直方向の上面に開口部を有した容器本体と、前記容器本体に着脱可能に取り付けられ前記開口部を開閉する本発明に記載の容器用蓋材とを具備したことを特徴とする。
この発明では、本発明の容器用蓋材を用いるので、簡単な構成で、損傷を抑制でき、係脱部が不用意に外れてしまうことを防止できるとともに、押圧力を作用する簡単な動作で容器本体に容易で確実に取り付けでき、当該容器用蓋材を肉薄に形成することも容易にでき、軽量化や材料コストの低減も容易に図れる。 The container of the present invention comprises a container body having an opening on the upper surface in the vertical direction, and a container lid according to the present invention that is detachably attached to the container body and opens and closes the opening. Features.

そして、本発明では、前記容器本体は、前記開口部の外周側から外方に向けて延設され、前記容器用蓋材の外周縁が当接する当接部を備えている構成とすることが好ましい。
この発明では、開口部の外周側から外方に向けて延設した当接部に、容器用蓋材の外周縁が当接することで、摩擦により容器用蓋材の外周縁が外方へ広がるように変形することが抑制され、変形による割れなどの損傷を防止できる。 And in this invention, it is set as the structure which the said container main body is equipped with the contact part extended outward from the outer peripheral side of the said opening part, and the outer periphery of the said cover material for containers contact | abuts. preferable.

And a second step portion 33B provided in a shape.
More specifically, the first step portion 33A is formed to be bent inward from the upper end of the side wall portion 31A of the engagement / disengagement portion 31 and to have a plane substantially along the horizontal plane. On the inner peripheral edge of the first stepped portion 33A, a rising portion 33C is bent upward. A second stepped portion 33B having a plane substantially along a horizontal plane is bent toward the inner edge of the upper end 33C. The second stepped portion 33 </ b> B has an inner peripheral edge formed continuously with the lower end edge of the side surface portion 32 </ b> B of the top surface portion 32. The raised portion 33C is formed so as to be positioned near the upper end of the opening 21 of the container body 2 when attached to the container body 2, and the first step portion 33A is configured to have a predetermined width. ing.

第一段差部３３Ａは、幅寸法が厚さ寸法に対して２．５倍以下となるように構成されていることが好ましい。
ここで、２．５倍より幅広になると、蓋材３に外力が加わった際に、第二段差部３３Ｂと同様に弾性変形し、蓋材３の外周縁である係脱部３１の下端縁が外側に広がるように弾性変形し、当接部２６から外れて当接部２６の先端を支点として大きく広げられる状態となり、割れが生じたり、係脱部３１が伸ばされて容器本体２に係脱できなくなったりするなどの不都合を生じるおそれがある。 33 A of 1st level | step-difference parts are preferably comprised so that a width dimension may be 2.5 times or less with respect to a thickness dimension.
Here, when it becomes wider than 2.5 times, when an external force is applied to the lid member 3, it is elastically deformed in the same manner as the second stepped portion 33 </ b> B, and the lower edge of the engagement / disengagement portion 31 that is the outer peripheral edge of the lid member 3. Is elastically deformed so as to spread outward, and is disengaged from the abutting portion 26 and is greatly expanded with the tip of the abutting portion 26 as a fulcrum. There is a risk of inconvenience such as being unable to remove.

そして、段差部３３は、係脱部３１から天面部３２に渡る方向の第二段差部３３Ｂの幅寸法が、第一段差部３３Ａの幅寸法より幅広、好ましくは第一段差部３３Ａの幅寸法に対して２倍以上１０倍以下、より好ましくは３倍以上５倍以下となるように形成されている。
ここで、２倍より幅狭になると、第二段差部３３Ｂの十分な弾性変形が得られず、外力を十分に吸収できなくなり、損傷するおそれがあるとともに、蓋材３の外周縁が外方に広がる弾性変形が大きくなって、容器本体２との適切な係合状態が得られなくなるおそれがある。一方、１０倍より幅広になると、蓋材３を容器本体２に取り付ける際の押圧力が係脱部３１に作用しにくくなり、良好な着脱感が得られにくくなるおそれがある。 In the step portion 33, the width dimension of the second step portion 33B in the direction from the engaging / disengaging portion 31 to the top surface portion 32 is wider than the width dimension of the first step portion 33A, preferably the width dimension of the first step portion 33A. However, it is formed to be 2 to 10 times, more preferably 3 to 5 times.
Here, if the width is smaller than twice, sufficient elastic deformation of the second stepped portion 33B cannot be obtained, the external force cannot be sufficiently absorbed, and there is a possibility that the outer peripheral edge of the lid member 3 is outward. There is a possibility that the elastic deformation spreading to the inside becomes large and an appropriate engagement state with the container body 2 cannot be obtained. On the other hand, when it becomes wider than 10 times, the pressing force when attaching the lid member 3 to the container body 2 is less likely to act on the engagement / disengagement part 31, and it may be difficult to obtain a good feeling of attachment / detachment.

さらに、第二段差部３３Ｂの幅寸法（Ｌ２）と厚さ寸法（Ｈ２）の比（Ｌ２／Ｈ２）は、第一段差部３３Ａの幅寸法（Ｌ１）と厚さ寸法（Ｈ１）の比（Ｌ１／Ｈ１）に対して、好ましくは２倍以上１０倍以下となるように形成されている。
ここで、２倍より幅狭になると、第二段差部３３Ｂの十分な弾性変形が得られず、外力を十分に吸収できなくなり、損傷するおそれがあるとともに、蓋材３の外周縁が外方に広がる弾性変形が大きくなって、容器本体２との適切な係合状態が得られなくなるおそれがある。一方、１０倍より幅広になると、蓋材３を容器本体２に取り付ける際の押圧力が係脱部３１に作用しにくくなり、良好な着脱感が得られにくくなるおそれがある。 Furthermore, the ratio (L2 / H2) of the width dimension (L2) and the thickness dimension (H2) of the second stepped portion 33B is the ratio of the width dimension (L1) and the thickness dimension (H1) of the first stepped portion 33A ( L1 / H1) is preferably formed to be 2 times or more and 10 times or less.
Here, if the width is smaller than twice, sufficient elastic deformation of the second stepped portion 33B cannot be obtained, the external force cannot be sufficiently absorbed, and there is a possibility that the outer peripheral edge of the lid member 3 is outward. There is a possibility that the elastic deformation spreading to the inside becomes large and an appropriate engagement state with the container body 2 cannot be obtained. On the other hand, when it becomes wider than 10 times, the pressing force when attaching the lid member 3 to the container body 2 is less likely to act on the engagement / disengagement part 31, and it may be difficult to obtain a good feeling of attachment / detachment.

［容器の変形状況］
次に、上記容器に外力が作用した状況について図４を参照して説明する。
例えば、容器が落下するなどにより、蓋材３に外力が作用した際、まず蓋材３の側壁部３１Ａの下端が容器本体２の当接部２６に押し付けられる状態となり、側壁部３１Ａの下端と当接部２６との間の摩擦力が増大する。そして、さらなる外力により、図４に示す二点鎖線の状態から実線で示す状態に、蓋材３が弾性変形する。
具体的には、天面部３２の側面部３２Ｂの下端が下方に沈み込むように、第二段差部３３Ｂが弾性変形するとともに、第二段差部３３Ｂと天面部３２の側面部３２Ｂとの連結部分が互いに近接するように鋭角に弾性変形する。さらに、第二段差部３３Ｂの弾性変形により立上部３３Ｃが引っ張られるように弾性変形する。なお、第一段差部３３Ａは、幅寸法が厚さ寸法に対して所定の幅狭に形成されているので、第一段差部３３Ａ近傍の剛性が他の部位より高くなっており、第一段差部３３Ａおよびその近傍ではほとんど弾性変形しない。
さらに、第二段差部３３Ｂが大きく弾性変形して、立上部３３Ｃが引っ張られるように弾性変形しても、側壁部３１Ａの下端と当接部２６との間の摩擦力により、係脱部３１の側壁部３１Ａの上端側が内側に引っ張られるように多少撓む程度で、側壁部３１Ａの下端が外方に広がるような弾性変形はあまり生じない。 [Deformation of containers]
Next, a situation where an external force is applied to the container will be described with reference to FIG.
For example, when an external force is applied to the lid member 3 due to a container falling or the like, first, the lower end of the side wall portion 31A of the lid member 3 is pressed against the contact portion 26 of the container body 2, and the lower end of the side wall portion 31A is The frictional force with the contact part 26 increases. Then, the lid member 3 is elastically deformed from the two-dot chain line state shown in FIG. 4 to the state indicated by the solid line by a further external force.
Specifically, the second stepped portion 33B is elastically deformed so that the lower end of the side surface portion 32B of the top surface portion 32 sinks downward, and the connecting portion between the second stepped portion 33B and the side surface portion 32B of the top surface portion 32. Are elastically deformed at an acute angle so as to be close to each other. Further, the upright portion 33C is elastically deformed by the elastic deformation of the second step portion 33B. Since the first step portion 33A is formed with a width dimension that is a predetermined width smaller than the thickness dimension, the first step portion 33A has a higher rigidity in the vicinity of the first step portion 33A than the other portions. Almost no elastic deformation occurs in the portion 33A and the vicinity thereof.
Furthermore, even if the second step portion 33B is greatly elastically deformed and elastically deformed so that the upright portion 33C is pulled, the engagement / disengagement portion 31 is caused by the frictional force between the lower end of the side wall portion 31A and the contact portion 26. The side wall 31A is slightly deformed so that the upper end of the side wall 31A is pulled inward, and elastic deformation such that the lower end of the side wall 31A spreads outward does not occur so much.

このように、上記実施形態では、第一段差部３３Ａおよび当該第一段差部３３Ａより幅広な第二段差部３３Ｂを段差状に設けたので、外力が加わっても、第二段差部３３Ｂにより外力を吸収し、係脱部３１が広がって当接部２６の先端から外れてしまい、係脱部３１が当接部２６の先端を支点として大きく広げられる状態となり、割れが生じたり伸びたりして損傷したり、係止爪部２７と係合爪部３１Ｂとの係合が得られなくなって蓋材３が容器本体２に係合できなくなったりすることを防止できる。
さらに、外力が加わった際に係脱部３１の側壁部３１Ａの下端が当接して摩擦力を生じさせる当接部２６を設けたことにより、より係脱部３１が外方に広げられる弾性変形が抑制され、より損傷を防止できる。
そして、外力が解除されると、仮に係脱部３１の係合爪部３１Ｂが容器本体２の係止爪部２７から外れた状態となっていても、蓋材３の復元により、係脱部３１の側壁部３１Ａが立壁部２５に重なるように近接して再び係合状態が得られるので、蓋材３が容器本体２から外れてしまうことを抑制できる。 Thus, in the said embodiment, since the 2nd step part 33B wider than the 1st step part 33A and the said 1st step part 33A was provided in step shape, even if external force is added, external force is applied by the 2nd step part 33B. The engaging / disengaging part 31 spreads and disengages from the tip of the abutting part 26, and the engaging / disengaging part 31 is greatly expanded with the tip of the abutting part 26 as a fulcrum. It can be prevented that the lid member 3 cannot be engaged with the container body 2 due to damage or the engagement between the locking claw portion 27 and the engagement claw portion 31B cannot be obtained.
Further, when the external force is applied, the lower end of the side wall portion 31A of the engagement / disengagement portion 31 is brought into contact with the contact portion 26 for generating a frictional force, so that the engagement / disengagement portion 31 is further expanded outward. Is suppressed, and damage can be prevented more.
When the external force is released, even if the engagement claw portion 31B of the engagement / disengagement portion 31 is disengaged from the engagement claw portion 27 of the container body 2, the engagement / disengagement portion is recovered by the restoration of the lid member 3. Since the engagement state is obtained again so that the side wall portion 31 </ b> A of 31 comes close to the standing wall portion 25, it is possible to prevent the lid member 3 from being detached from the container body 2.

一方、蓋材３を容器本体２に係合させて開口部２１を閉塞する通常動作の場合、容器本体２の立壁部２５の外周側に蓋材３の係脱部３１を嵌め合わせる。そして、係脱部３１の係合爪部３１Ｂが容器本体２の係止爪部２７に乗り上げる状態となる。この状態で、利用者が蓋材３に押圧力を作用させると、第二段差部３３Ｂが多少弾性変形するが他の部位はほとんど弾性変形せず、係合爪部３１Ｂが係止爪部２７を乗り越えるとともに、側壁部３１Ａの下端が当接部２６に当接して、蓋材３が容器本体２に取り付けられる。
このように、押圧力を作用させて蓋材３を取り付ける通常動作の場合には、第一段差部３３Ａの剛性により、係脱部３１の側壁部３１Ａの下端が外方へ広がるように弾性変形することが抑制されるので、係脱部３１に押圧力が有効に作用し、係脱部３１の係合爪部３１Ｂが容器本体２の係止爪部２７を乗り越えるとともに、側壁部３１Ａの下端が当接部２６に当接して、蓋材３の良好な取付感を提供できる。 On the other hand, in the normal operation of closing the opening 21 by engaging the lid 3 with the container body 2, the engaging / disengaging part 31 of the lid 3 is fitted on the outer peripheral side of the standing wall 25 of the container body 2. Then, the engagement claw portion 31B of the engagement / disengagement portion 31 rides on the engagement claw portion 27 of the container body 2. In this state, when the user applies a pressing force to the lid member 3, the second step portion 33 </ b> B is somewhat elastically deformed, but the other portions are hardly elastically deformed, and the engaging claw portion 31 </ b> B is the locking claw portion 27. , The lower end of the side wall portion 31 </ b> A comes into contact with the contact portion 26, and the lid member 3 is attached to the container body 2.
As described above, in the case of a normal operation in which the lid member 3 is attached by applying a pressing force, due to the rigidity of the first step portion 33A, elastic deformation is performed so that the lower end of the side wall portion 31A of the engagement / disengagement portion 31 spreads outward. Therefore, the pressing force effectively acts on the engagement / disengagement portion 31, the engagement claw portion 31B of the engagement / disengagement portion 31 gets over the engagement claw portion 27 of the container body 2, and the lower end of the side wall portion 31A. Can be brought into contact with the contact portion 26 to provide a good feeling of attachment of the lid member 3.

特に、収容するマーガリンは、外部環境により液状化または固形化するので、マーガリンが漏れ出ることを防止するための寸法精度が必要で、かつ内容物のマーガリンを利用する毎に開口部２１の開閉動作が実施され、繰り返される開閉動作毎に押圧力が良好に係脱部３１に作用して良好な開閉感を提供する必要があることから、射出成形した容器１により、良好な寸法精度が得られ、内容物の適切な収容と、蓋材３の良好な開閉が得られる。さらに、射出成形により、誤って落下して外力が作用しても損傷しない材料を選定することが容易にできる。   In particular, since the margarine to be contained is liquefied or solidified depending on the external environment, dimensional accuracy is required to prevent the margarine from leaking, and the opening / closing operation of the opening 21 is performed each time the content margarine is used. Since the pressing force is applied to the engagement / disengagement part 31 for each repeated opening / closing operation and it is necessary to provide a good opening / closing feeling, the injection molded container 1 can provide a good dimensional accuracy. Appropriate accommodation of the contents and good opening and closing of the lid 3 are obtained. Furthermore, by injection molding, it is possible to easily select a material that is accidentally dropped and is not damaged even when an external force is applied.

そして、上記実施形態では、係脱部３１の鉛直方向に略沿った平面を有した側壁部３１Ａに対して、水平方向に略沿った平面を有した平板状に第一段差部３３Ａを折曲状に形成し、第二段差部３３Ｂも水平方向に略沿った平面を有した平板状に形成している。
このため、係脱部３１の側壁部３１Ａに対して第一段差部３３Ａおよび第二段差部３３Ｂが略直交する状態となり、蓋材３を潰すような外力が作用すると、外力に対して交差する平面となる第二段差部３３Ｂが第一段差部３３Ａに比して大きく弾性変形し、より外力による損傷を防止できるとともに、容器本体２と蓋材３とのより確実な係脱状態が得られる。 And in the said embodiment, with respect to the side wall part 31A which has the plane which followed the vertical direction of the engagement / disengagement part 31, the 1st level | step-difference part 33A was bent in the flat form which has the plane substantially along the horizontal direction. The second stepped portion 33B is also formed in a flat plate shape having a plane substantially along the horizontal direction.
For this reason, when the first step portion 33A and the second step portion 33B are substantially orthogonal to the side wall portion 31A of the engagement / disengagement portion 31 and an external force that crushes the lid member 3 acts, it intersects the external force. The flat second step portion 33B is greatly elastically deformed as compared with the first step portion 33A, so that damage due to external force can be prevented and a more reliable engagement / disengagement state between the container body 2 and the lid member 3 can be obtained. .

さらに、上記実施形態では、第二段差部３３Ｂの外周縁を立上部３３Ｃを介して第一段差部３３Ａに連続させ第二段差部３３Ｂを第一段差部３３Ａに隣接する段差とし、第二段差部３３Ｂの内周縁を天面部３２に連続して設けている。
そして、立上部３３Ｃは、容器本体に取り付けたときに、容器本体２の開口部２１の上端部の直上付近に位置するように形成され、第一段差部３３Ａが所定の幅狭に構成されている。
このため、第二段差部３３Ｂの幅寸法を大きく設計しても、第二段差部３３Ｂの一端は蓋材３の外周側に位置することになる。外力が天面部３２に作用しても、第一段差部３３Ａおよびその近傍がほとんど弾性変形せず、第二段差部３３Ｂによる外力に対する十分な弾性変形が得られる状態が得られるため、蓋材３が損傷することを防止できる。 Furthermore, in the said embodiment, the outer periphery of the 2nd level | step-difference part 33B is made to follow the 1st level | step-difference part 33A via the upright part 33C, and the 2nd level | step-difference part 33B is made into the level | step difference adjacent to the 1st level | step-difference part 33A, The inner peripheral edge of the portion 33 </ b> B is provided continuously to the top surface portion 32.
The raised portion 33C is formed so as to be positioned in the vicinity of the upper end portion of the opening 21 of the container body 2 when attached to the container body, and the first step portion 33A is configured to have a predetermined width. Yes.
For this reason, even if the width dimension of the 2nd level | step-difference part 33B is designed large, the end of the 2nd level | step-difference part 33B will be located in the outer peripheral side of the cover material 3. FIG. Even if an external force acts on the top surface portion 32, the first step portion 33A and the vicinity thereof are hardly elastically deformed, and a state in which sufficient elastic deformation with respect to the external force by the second step portion 33B can be obtained is obtained. Can be prevented from being damaged.

また、上記実施形態では、天面部３２における段差部３３に延設する側面部３２Ｂの平面と第二段差部３３Ｂの平面とのなす角が８５°以上９５°未満としている。
このため、外力が作用した際に、天面部３２と段差部３３との連結部分の近傍で天面部３２と段差部３３とのなす角が小さくなる状態に鋭角に変形し易く、外力に対してより弾性変形しやすくなり、蓋材３の外力による損傷をより防止できるとともに、容器本体２と蓋材３とのより確実な係脱状態が得られる。 Moreover, in the said embodiment, the angle | corner which the plane of the side part 32B extended in the level | step-difference part 33 in the top | upper surface part 32 and the plane of the 2nd level | step-difference part 33B makes 85 degrees or more and less than 95 degrees.
For this reason, when an external force is applied, it is easily deformed to an acute angle so that the angle formed between the top surface portion 32 and the step portion 33 becomes small near the connection portion between the top surface portion 32 and the step portion 33. It becomes easier to be elastically deformed, and damage due to the external force of the lid member 3 can be further prevented, and a more reliable engagement / disengagement state between the container body 2 and the lid member 3 can be obtained.

さらに、上記実施形態では、開口部２１の外周側から外方に向けて当接部２６を延設し、蓋材３の外周縁である側壁部３１Ａの下端が当接する構成としている。
このため、側壁部３１Ａの下端と当接部２６との摩擦により、蓋材３の側壁部３１Ａの下端が外方へ広がるように変形することが抑制され、変形による割れなどの損傷をより確実に防止できるとともに、容器本体２と蓋材３とのより確実な係脱状態が得られる。 Furthermore, in the said embodiment, the contact part 26 is extended toward the outward from the outer peripheral side of the opening part 21, and it is set as the structure which the lower end of 31 A of side wall parts which are the outer periphery of the cover material 3 contact | abut.
Therefore, the friction between the lower end of the side wall portion 31A and the contact portion 26 prevents the lower end of the side wall portion 31A of the lid member 3 from being deformed so as to spread outward, and damage such as cracks due to the deformation is more reliably ensured. In addition, a more reliable engagement / disengagement state between the container body 2 and the lid member 3 can be obtained.
