Abstract
Description
本発明は食品保管用等に使用される保管容器に関する。 The present invention relates to a storage container used for food storage and the like.
食品を入れるポリエチレン製の密封容器等の食品用保管容器は内容物を保護するため密閉性が重要であることから、例えば、蓋体側壁と容器本体周壁とのそれぞれに突部を設けて、これら突部を嵌合させることで蓋体の嵌合力を高めることが行われている(特許文献1)。が、そうすると蓋が開けにくくなるため、蓋を弾性変形容易な形状とすることで蓋を開けやすくすることが行われている。 For food storage containers such as polyethylene sealed containers that contain food, sealability is important to protect the contents.For example, these are provided with protrusions on the lid side wall and the container body peripheral wall. Increasing the fitting force of the lid by fitting the protrusion is performed (Patent Document 1). However, since it becomes difficult to open the lid, it is easy to open the lid by making the lid easily elastically deformed.
しかしながら、容器が四角形状の場合には、蓋を開けようとすると、摘み部が設けられた蓋角部の両隣の角部に内方向への引張力が作用するため、蓋側壁の角部に位置する突部が内方へ引寄せられて容器本体周壁の角部に位置する突部下端へさらに食い込むため、開蓋時に蓋の嵌合力が増大するという課題があった。 However, when the container has a quadrangular shape, when an attempt is made to open the lid, an inward tensile force acts on both corners of the lid corner where the knob is provided. Since the protruding portion that is positioned is drawn inward and further bites into the lower end of the protruding portion that is positioned at the corner of the peripheral wall of the container body, there is a problem that the fitting force of the lid increases when the lid is opened.
本発明は、上記課題を解決するためになされたもので、開蓋時における蓋の嵌合力の増大防止を図った保管容器を提供することを目的とする。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a storage container that prevents an increase in the fitting force of the lid when the lid is opened.
上記課題を解決するために、本発明は、四角形状の蓋体1の頂板2周縁部に下面開口の嵌合溝部6を設けて、該嵌合溝部を容器体20の周壁21へ嵌合させると共に、前記蓋体1の少なくとも対向する2つの角部における嵌合溝部6の外側壁5に薄肉部8を設けたことを特徴とする。 In order to solve the above-mentioned problem, the present invention provides a fitting groove portion 6 having a lower surface opening at the peripheral edge portion of the top plate 2 of the quadrangular lid body 1 and fits the fitting groove portion to the peripheral wall 21 of the container body 20. In addition, a thin portion 8 is provided on the outer wall 5 of the fitting groove 6 at at least two opposing corners of the lid 1.
また、本発明は、前記嵌合溝部6を、前記頂板2周縁から起立する内側壁3と、該内側壁上端から外向きフランジ4を介して垂下する外側壁5とで形成すると共に、前記容器本体の周壁21上部外面に第1嵌合突条22を周設して、該第1嵌合突条22へ前記嵌合溝部6の上部を嵌合させ、また、前記蓋体1の角部を除く前記嵌合溝部6部分の外側壁5内面に第2嵌合突条7を形成して、該第2嵌合突条7を前記容器本体周壁21の第1嵌合突条22下端へ係合させたことを特徴とする。 Further, according to the present invention, the fitting groove 6 is formed by an inner wall 3 rising from the periphery of the top plate 2 and an outer wall 5 depending from the upper end of the inner wall via an outward flange 4, and the container A first fitting protrusion 22 is provided around the outer surface of the upper part of the peripheral wall 21 of the main body, and the upper part of the fitting groove 6 is fitted to the first fitting protrusion 22, and the corner of the lid body 1 is fitted. A second fitting ridge 7 is formed on the inner surface of the outer wall 5 of the fitting groove portion 6 except for the second fitting ridge 7 to the lower end of the first fitting ridge 22 of the peripheral wall 21 of the container body. It is characterized by being engaged.
また、本発明は、前記薄肉部8を、前記蓋体1の対向する2つの角部における嵌合溝部6の外側壁5に設けるとともに、該薄肉部8を有しない残りの2つの角部の内の1つに摘み部を設けたことを特徴とする。 Further, according to the present invention, the thin portion 8 is provided on the outer wall 5 of the fitting groove portion 6 at the two opposite corner portions of the lid 1, and the remaining two corner portions not having the thin portion 8 are provided. One of them is provided with a knob.
さらに、本発明は、前記薄肉部8を前記蓋体1の3つの角部に設けたことを特徴とする。 Furthermore, the present invention is characterized in that the thin portion 8 is provided at three corners of the lid 1.
さらに、本発明は、前記薄肉部8を前記蓋体1の4つの角部に設けたことを特徴とする。 Further, the present invention is characterized in that the thin portion 8 is provided at four corners of the lid 1.
さらに、本発明は、前記薄肉部8は外方へ凸状に形成されていることを特徴とする。 Furthermore, the present invention is characterized in that the thin-walled portion 8 is formed to be convex outward.
さらに、本発明は、前記薄肉部8は側方視三角形状に形成されていることを特徴とする。 Furthermore, the present invention is characterized in that the thin portion 8 is formed in a triangular shape in a side view.
本発明は、蓋体の角部に薄肉部8を設けたので、開蓋時に蓋体の一部が上方へ弾性変形して頂板2に内方向への引張力が作用してもこの引張力は薄肉部8の弾性変形によって低減されるため、蓋体の角部に内方への引張力が作用しても蓋体の嵌合溝部6の外側壁5が内方へ弾性変形して容器本体周壁21の第1嵌合突条22へ圧接することが防止されることとなって開けにくさが解消される。 In the present invention, since the thin portion 8 is provided at the corner portion of the lid, even if a part of the lid is elastically deformed upward when the lid is opened and this tensile force acts on the top plate 2 inward. Is reduced by elastic deformation of the thin-walled portion 8, so that the outer wall 5 of the fitting groove portion 6 of the lid body is elastically deformed inward even when an inward tensile force acts on the corner portion of the lid body. Since it is prevented from being pressed against the first fitting protrusion 22 of the main body peripheral wall 21, it is difficult to open.
また、本発明は、蓋体の3つの角部に薄肉部8を設けたので、真中に位置する角部の薄肉部下端に指を掛けて外方へ引けば薄肉部が伸びて外方へ広がるため、指を角部内へ差し込み掛けることが容易であり、このように薄肉部8を指掛け用の摘み部として利用することができるため、外方へ突出する摘み部を突設する必要がなく、したがって、容器自体を収納する際に摘み部が邪魔になるということがない。 Further, according to the present invention, since the thin portion 8 is provided at the three corner portions of the lid, if the finger is placed on the lower end of the thin portion of the corner portion located in the middle and pulled outward, the thin portion is extended outward. Since it spreads, it is easy to insert a finger into the corner portion, and the thin-walled portion 8 can be used as a finger gripping portion in this way, so there is no need to project a knob portion protruding outward. Therefore, the knob does not get in the way when the container itself is stored.
さらに、本発明は、前記薄肉部8を前記蓋体1の4つの角部に設けたので、開蓋に際してはどの薄肉部8も摘み部として利用することができ、したがって特定の摘み部を選択する必要がなく、換言すれば薄肉部が3つの場合には真中に位置する薄肉部を選択しなければならないのに対し、4つの場合には開蓋に際して特定の薄肉部の選択という考慮を必要としないことから開蓋の容易性が達成される。 Further, in the present invention, since the thin portion 8 is provided at the four corners of the lid body 1, any thin portion 8 can be used as a knob when opening the lid, and therefore a specific knob is selected. In other words, when there are three thin-walled parts, the thin-walled part located in the middle must be selected, whereas in the case of four thin-walled parts, it is necessary to consider the selection of a specific thin-walled part when opening the lid. Therefore, it is easy to open the lid.
さらに、本発明は、薄肉部8は外方へ凸状に形成されているので、開蓋時に薄肉部8へ指を掛けることがさらに容易である。 Furthermore, in the present invention, since the thin portion 8 is formed in a convex shape outward, it is easier to put a finger on the thin portion 8 when the lid is opened.
さらに、本発明は、蓋体の頂板2周縁部に嵌合溝部6を設けて、該嵌合溝部を容器本体の周壁21へ嵌合させたので、容器の密閉性がよい。 Further, according to the present invention, the fitting groove 6 is provided on the peripheral edge of the top plate 2 of the lid, and the fitting groove is fitted to the peripheral wall 21 of the container main body.
以下、本発明の実施の形態について、図面を参照しながら詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
1は蓋体で、四角形状の頂板2の周縁から内側壁3を起立させ、内側壁3の上端から外向きフランジ4を介して外側壁5を垂下することにより内側壁3と外向きフランジ4と外側壁5とで嵌合溝部6を形成する。嵌合溝部6は後述の容器本体の第1嵌合突条22へ嵌合させる。 Reference numeral 1 denotes a lid, and the inner wall 3 is erected from the peripheral edge of the rectangular top plate 2 and the outer wall 5 is suspended from the upper end of the inner wall 3 via the outward flange 4, whereby the inner wall 3 and the outward flange 4 are suspended. And the outer wall 5 form a fitting groove 6. The fitting groove 6 is fitted to a first fitting protrusion 22 of the container body described later.
図3に示すように蓋体1の角部を除く外側壁5の上下方向中間部内面に第2嵌合突条7を周設すると共に、蓋体1の角部10、11、12、13に弾性変形自在な薄肉部8を形成する。薄肉部8は断面形状が外方へ凸状であれば特に限定はないが、通常はU字状、V字状、コ字状等に形成する。また薄肉部8は底辺が下方に位置する側方視三角形状であることが好ましい。 As shown in FIG. 3, the second fitting protrusion 7 is provided around the inner surface of the vertical intermediate portion of the outer wall 5 excluding the corner of the lid 1, and the corners 10, 11, 12, 13 of the lid 1 are provided. The thin-walled portion 8 that is elastically deformable is formed. The thin portion 8 is not particularly limited as long as the cross-sectional shape is outwardly convex, but is usually formed in a U shape, a V shape, a U shape, or the like. Moreover, it is preferable that the thin part 8 is a side view triangle shape in which a base is located below.
薄肉部8の数には特に限定がないが、薄肉部8は蓋体1を開ける際に周方向へ伸びることで開蓋を容易にするためのものであるから、この目的を達成し得る程度の数であればよく、また薄肉部8間の間隔もさらには薄肉部8の上端8aの位置も同様の観点から決めることができる。 The number of the thin portions 8 is not particularly limited, but the thin portions 8 are intended to facilitate opening by extending in the circumferential direction when the lid 1 is opened. The interval between the thin portions 8 and the position of the upper end 8a of the thin portion 8 can be determined from the same viewpoint.
薄肉部8は、上記のように蓋体1の4つの角部10、11、12、13のすべてに設けてもよく、または3つの角部10、11、12だけに設けてもよい。これらの場合には1つの角部(例えば、角部10)に位置する薄肉部8は開蓋する際に、指を掛けるために利用することができる。なお、薄肉部8を3つの角部10、11、12だけに設ける場合には、真中に位置する角部10を指掛け部として利用する。薄肉部8の数は上記に限らず、蓋体1の対向する2つの角部にのみ設けることも可能である。この場合には薄肉部8を有しない残りの2つの角部の内の1つに摘み部(図示せず)を設ける。 As described above, the thin portion 8 may be provided on all the four corner portions 10, 11, 12, 13 of the lid 1, or may be provided only on the three corner portions 10, 11, 12. In these cases, the thin-walled portion 8 located at one corner (for example, the corner 10) can be used to hang a finger when the lid is opened. In addition, when providing the thin part 8 only in the three corner | angular parts 10, 11, and 12, the corner | angular part 10 located in the center is utilized as a finger hook part. The number of the thin-walled portions 8 is not limited to the above, and the thin-walled portions 8 can be provided only at two opposite corners of the lid 1. In this case, a knob (not shown) is provided at one of the remaining two corners not having the thin portion 8.
20は容器本体で、周壁21の上端部外面に第1嵌合突条22を周設する。蓋体1を容器本体20へ嵌合させると、図3に示すように嵌合溝部6の上部が第1嵌合突条22へ嵌合すると共に、第2嵌合突条7が第1嵌合突条22下端へ嵌合する。 Reference numeral 20 denotes a container body, and a first fitting protrusion 22 is provided around the outer surface of the upper end portion of the peripheral wall 21. When the lid 1 is fitted to the container body 20, the upper part of the fitting groove 6 is fitted to the first fitting protrusion 22 and the second fitting protrusion 7 is first fitted as shown in FIG. It is fitted to the lower end of the mating ridge 22.
次に本実施形態の作用について説明する。
蓋体1を開けるには、蓋体1の4つの角部10、11、12、13に薄肉部8が設けられている場合、任意の1つの角部に設けられた薄肉部8下端に指を掛けて外方へ引けばよく、すると図4、5に示すように薄肉部8が伸びて外方へ広がるため、指を角部内へ差し込んで掛けることができる。このように蓋体1の4つの角部10、11、12、13に薄肉部8が設けられている場合には、いずれの薄肉部も指掛け用として利用することができる。
Next, the operation of this embodiment will be described.
To open the lid 1, when the thin portions 8 are provided at the four corners 10, 11, 12, 13 of the lid 1, the finger is applied to the lower end of the thin portion 8 provided at any one corner. 4 and 5 so that the thin-walled portion 8 extends and spreads outward as shown in FIGS. 4 and 5, so that a finger can be inserted into the corner portion and hung. Thus, when the thin part 8 is provided in the four corner | angular parts 10, 11, 12, and 13 of the cover body 1, any thin part can be utilized for a finger hook.
次いで、薄肉部8を持ち上げると、指を掛けた角部側の蓋体部分が上方へ弾性変形するため、頂板2の角部に内方向への引張力が作用するが、この引張力は指を掛けた薄肉部8の両隣に位置する角部11、12に設けた薄肉部の弾性変形によって低減されるため、蓋体の角部に内方への引張力が作用しても蓋体の嵌合溝部6の外側壁5が内方へ弾性変形して容器本体周壁21の第1嵌合突条22へ圧接することが防止されることとなって開けにくさが解消される。 Next, when the thin-walled portion 8 is lifted, the lid portion on the corner portion on which the finger is hung is elastically deformed upward, so that an inward tensile force acts on the corner portion of the top plate 2. Is reduced by elastic deformation of the thin wall portions provided at the corner portions 11 and 12 located on both sides of the thin wall portion 8 that is hung, so that even if an inward tensile force acts on the corner portions of the lid body, It is prevented that the outer wall 5 of the fitting groove 6 is elastically deformed inward and is pressed against the first fitting protrusion 22 of the peripheral wall 21 of the container body, so that the difficulty of opening is eliminated.
なお、蓋体1の材質としてはポリエチレン等の柔軟な材料を使用する。 Note that the lid 1 is made of a flexible material such as polyethylene.
