【０００７】
【発明の実施の形態】
この発明に係る蓋付き容器としてメガネケースを例にとり、その詳細を説明すると以下のとおりである。
【０００８】
図１，２は、蓋３が容器２に対しスナップ係合して閉じた状態にあるメガネケース１の斜視図と、蓋が開いた状態にあるメガネケース１の斜視図である。かかるメガネケース１は、これに例えば水中メガネを入れて陳列棚等に吊り下げておくことができるように形成されているもので、ほぼ長円形に形成された容器２と、容器２とほぼ同じように長円形に作られた蓋３とを有する。容器２と蓋３とは、それぞれ水平面内において互いに直交し、メガネケース１の幅と長さとを二等分する長軸６と短軸７とを有する。容器２は、長軸６方向ヘ延びるフック５を有し、このフック５を除くと、容器２と蓋３とは長軸６と短軸７とのそれぞれに関して対称に形成されている。この意味において、容器２と蓋３とは、長軸６と短軸７とに関して実質的に対称である。フック５は、蓋付き容器１を吊り下げるために使用するものであるから、吊り下げる必要がないときには省くことができる。
【０００９】
容器２は、底部８と開口９とを有し、開口９の周縁部１１が長軸６方向において弧を画いて互いに向かい合う第１末端部分１２と、これら第１末端部分１２の間に延びて長軸６を挟んで互いに並行する第１中間部分１３とを有する。第１末端部分１２では周縁部１１の頂縁１４が平坦に形成されている。第１中間部分１３では、図の上下方向において第１末端部分１２の近傍で周縁部１１の頂縁１４が下向きに湾曲する第１部位１６と、第１部位１６と１６との間にあって上向きに湾曲する第２部位１７とを有する。周縁部１１の内側には溝１５が形成されている。かかる容器２は、蓋３よりも可撓性の高い軟質弾性材料、例えば低密度ポリエチレンやポリプロピレン、ナイロン等で形成される。
【００１０】
蓋３は、頂部１８と周壁部２１とを有し、周壁部２１が長軸６方向において弧を画いて互いに向かい合う第２末端部分２２と、これら第２末端部分２２の間に延びて長軸６を挟んで互いに並行する第２中間部分２３とを有する。蓋３の周壁部２１の外面には、蓋３を周回する外側リブ２４が形成されている。外側リブ２４は、容器２の頂縁１４に倣う曲線を画いて延びており、第２末端部分２２では部分４１が平坦に、第２中間部分２３のうちで第２末端部分２２につながるところでは部分４３が緩やかな傾斜を持ちながら、容器２の第１部位１６の直上では部分２５が下向きに凸となり、また部分２５と２５との間では部分４０が急な傾斜で上向きに凸となるように延びている。図の上下方向において外側リブ２４の下には下方周縁部２６が形成されている。蓋３が容器２に対して閉じた状態にあるときに、下方周縁部２６が容器２の溝１５に納まり、外側リブ２４が容器２の頂縁１４に当接するかまたはわずかに上方へ離間している。かかる蓋３は、容器２よりも可撓性の低い硬質弾性材料、例えばブタジエンとスチレンとの共重合樹脂、ＡＢＳ樹脂、ポリカーボネート樹脂等によって形成される。
【００１１】
図３〜５は、容器２と蓋３とがスナップ係合した状態を示す図１の断面図である。
【００１２】
図３は、図１において容器２の第１末端部分１２のうちの一方を横切るＩＩＩ−ＩＩＩ線に沿った断面を示す。容器２の周縁部１１は、その内側に水平方向において容器２の内方ヘ突出する内側リブ３１を有する。内側リブ３１は、突出した先端３２を起点として、容器２の内方から外方へ向かって次第に拡開するように傾斜を付けられた上面３３と下面３４とを有し、上面３３が頂縁１４にまで延び、下面３４が溝１５の底面３５にまで延びている。蓋３は、外側リブ２４が容器２の頂縁１４に当接した状態で示されている。蓋３の下方周縁部２６は、その全体または少なくともその外面３９に図の上方から下方へ向かうにつれて蓋３の外方へ広がるような傾斜がつけられており、蓋３が閉じた状態では、外面３９が内側リブ３１にスナップ係合してその下面３４に密着する。
【００１３】
図４は、図１において容器２の第１部位１６を横切るＩＶ−ＩＶ線に沿った断面を示す。容器２の第１部位１６には内側リブ３１が形成されておらず、かかる第１部位１６を形成している周縁部１１の内外面３６，３７は、ほぼ垂直かつ平滑に形成されている。蓋３の下方周縁部２６の内外面３８，３９もほぼ垂直に形成され、その外面３９は、周縁部１１の内面３６に密着している。
【００１４】
図５は、図１において容器２を第１部位１６と１６との間で横切るＶ−Ｖ線に沿った断面を示す。周縁部１１は、内側リブ３１が形成されておらず、ほぼ垂直で丈が高く、平滑な面を有している。蓋３の下方周縁部２６もまたほぼ垂直で丈が高く、その外面３９が容器２の内面３６に密着している。
【００１５】
図６〜８は、蓋３を閉じる前に蓋３を容器２に重ねたときの容器２と蓋３との部分断面図であって、これら容器２と蓋３との断面の位置は図３〜５の位置と同じである。
【００１６】
図６において、蓋３の下方周縁部２６はその下端４１の近傍が容器２における内側リブ３１の上面３３に上方から当接している。この状態にある蓋３を仮想線の如く下降させると、可撓性が低く変形しにくい下方周縁部２６で押圧された可撓性が高く変形しやすい容器２の周縁部１１が仮想線の如く外方へ弾性的に変形し、蓋３の下方周縁部２６が溝１５に納まるとともに、周縁部１１が弾性的に元の状態に復帰して、容器２と蓋３とがスナップ係合した図３の状態になる。かかる状態では、容器２の内側リブ３１の下面３４と蓋３の下方周縁部２６の外面３９とが密着し、蓋３は容易に外れることがない。
【００１７】
図７，８において、容器２の周壁部１１はほぼ垂直に、またはやや内側に傾いて上方へ延びている。蓋３の下方周縁部２６の外面３９は、図７の如く周壁部１１の斜め上方に位置しているか、図８の如く周壁部１１の上方部分に隣接している。これら図７，８における周壁部１１と下方周縁部２６との位置関係の相違は、両部１１，２６の丈の高さの相違によって生じる。蓋３を仮想線の如く下降させたときには、周縁部１１の内面３６と下方周縁部２６の外面３９とが接しながら、または周縁部１１を外方へ向かって僅かに変形させながら下方周縁部２６が溝１５に納まり、図４，５の状態となる。
【００１８】
図９は、蓋付き容器１の部分側面図であって、内側リブ３１が鎖線で示されている。図９と同じ状態にある蓋３が閉じた図１の蓋付き容器１では、容器２の第１部位１６とその直上に位置する蓋３の外側リブ２４とに指を当てて長軸６の両側から矢印４３，４４方向へ、つまり蓋付き容器１の幅を狭くするように力を加えると、力を加えた第１部位１６につながる容器２の第１末端部分１２とその第１部位１６に係合している蓋３の第２末端部分２２とが仮想線の如く長軸６方向ヘ長くなるように、かつ第１末端部分１２がやや下を向き、第２末端部分２２がやや上を向くように弾性的に変形する。これらの変形によって、容器２の内側リブ３１と蓋３の下方周縁部分２６との係合が解け、蓋３を開けることができる。容器２と蓋３とが閉じた状態にあるときには、容器２の内側リブ３１と蓋３の外側リブ２４の部分２５とがほぼ同一水平面内にあって、容器２の開口９の周り方向においてほぼ連続した一条の線を形成している。また、硬質材料からなる剛性の高い蓋３の外側リブ２４では、蓋３の第２末端部分２２に位置する外側リブ２４の部分４１と容器２の第１部位１６の直上に位置する部分２５との間が緩やかな傾斜を持つ部分４３を介してつながり、外側リブ２４はほぼ直線的に延びた状態にある。外側リブ２４がその部分２５で押圧されると、その変形が外側リブ２４を介して伝わり図９の仮想線の如き第２末端部分２２の変形となって現われる。一方の軟質材料からなる容器２も第１末端部分１２を形成する周縁部１１の剛性が内側リブ１２の存在によって高くなり、第１部位１６を押圧されたときの変形が内側リブ１２を介して伝わり仮想線の如き第１末端部分１２の変形となって現われる。しかも、蓋３は、容器２の全周のうちで第１末端部分１２においてのみスナップ係合しているから、第１、２末端部分１２，２２が互いに上下逆方向へ僅かに変形するだけで容器２から簡単に外れる。それゆえ、この容器２や蓋３では、蓋３を開けるための摘みを必要としない。このように蓋３が開くから、図１，２において容器２に設けられているフック５は、蓋付き容器２を吊り下げる必要がなければ省くことができる。
【００１９】
【発明の効果】
この発明に係る蓋付き容器は、その大きさにもよるが、容器と蓋とを上下方向から押圧すれば蓋を閉じることができ、蓋が閉じた容器はこれらを幅方向内方ヘ押圧すれば蓋を開けることができる。それゆえ、この発明では、蓋を開けるための摘みとなる突起を容器や蓋に設ける必要がない。

The glasses case 1 is formed so that, for example, underwater glasses can be put therein and hung on a display shelf or the like. And a lid 3 made in an oval shape. The container 2 and the lid 3 each have a long axis 6 and a short axis 7 that are orthogonal to each other in a horizontal plane, and bisect the width and length of the glasses case 1. The container 2 has a hook 5 extending in the long axis 6 direction. Excluding the hook 5, the container 2 and the lid 3 are formed symmetrically with respect to the long axis 6 and the short axis 7, respectively. In this sense, the container 2 and the lid 3 are substantially symmetric with respect to the long axis 6 and the short axis 7. Since the hook 5 is used for suspending the lidded container 1, it can be omitted when there is no need to suspend it.
[0009]
The container 2 has a bottom portion 8 and an opening 9, a peripheral portion 11 of the opening 9 forming an arc in the direction of the long axis 6 and facing each other, and extending between the first terminal portions 12. And a first intermediate portion 13 parallel to each other with the long axis 6 interposed therebetween. In the first end portion 12, the top edge 14 of the peripheral portion 11 is formed flat. In the first intermediate portion 13, a first portion 16 in which the top edge 14 of the peripheral portion 11 is curved downward in the vertical direction of the drawing in the vicinity of the first end portion 12, and is located between the first portions 16 and 16. And a second portion 17 that is curved. A groove 15 is formed inside the peripheral portion 11. The container 2 is formed of a soft elastic material having higher flexibility than the lid 3, for example, low-density polyethylene, polypropylene, nylon, or the like.
[0010]
The lid 3 has a top portion 18 and a peripheral wall portion 21, and the peripheral wall portion 21 forms an arc in the direction of the long axis 6 and faces each other, and extends between these second terminal portions 22 to extend along the long axis. 6 and a second intermediate portion 23 that is parallel to each other with the 6 interposed therebetween. On the outer surface of the peripheral wall portion 21 of the lid 3, an outer rib 24 circling the lid 3 is formed. The outer rib 24 extends in a curve following the top edge 14 of the container 2, where the portion 41 is flat at the second end portion 22 and where the second intermediate portion 23 connects to the second end portion 22. While the part 43 has a gentle slope, the part 25 becomes convex downward just above the first part 16 of the container 2, and the part 40 becomes convex upward with a steep slope between the parts 25 and 25. Extends. A lower peripheral portion 26 is formed below the outer rib 24 in the vertical direction of the drawing. When the lid 3 is closed with respect to the container 2, the lower rim 26 fits into the groove 15 of the container 2 and the outer ribs 24 abut the top edge 14 of the container 2 or move slightly upward. ing. The lid 3 is formed of a hard elastic material having lower flexibility than the container 2, for example, a copolymer resin of butadiene and styrene, an ABS resin, a polycarbonate resin, and the like.
[0011]
3 to 5 are sectional views of FIG. 1 showing a state where the container 2 and the lid 3 are snap-engaged.
[0012]
FIG. 3 shows a cross section along line III-III across one of the first end portions 12 of the container 2 in FIG. The peripheral portion 11 of the container 2 has inside ribs 31 protruding inward of the container 2 in the horizontal direction inside the container. The inner rib 31 has an upper surface 33 and a lower surface 34 which are inclined so as to gradually expand from the inside to the outside of the container 2 starting from the protruding tip 32, and the upper surface 33 has a top edge. 14, and the lower surface 34 extends to the bottom surface 35 of the groove 15. Lid 3 is shown with outer rib 24 abutting top edge 14 of container 2. The lower peripheral portion 26 of the lid 3 is inclined such that the entire outer surface or at least the outer surface 39 of the lower peripheral portion 26 spreads outward from the lid 3 as going downward from above in the figure. 39 snap-engages with the inner rib 31 and closely contacts the lower surface 34 thereof.
[0013]
FIG. 4 shows a cross section taken along line IV-IV across the first portion 16 of the container 2 in FIG. The inner rib 31 is not formed in the first portion 16 of the container 2, and the inner and outer surfaces 36 and 37 of the peripheral portion 11 forming the first portion 16 are formed substantially vertically and smoothly. The inner and outer surfaces 38 and 39 of the lower peripheral portion 26 of the lid 3 are also formed substantially vertically, and the outer surface 39 is in close contact with the inner surface 36 of the peripheral portion 11.
[0014]
FIG. 5 shows a cross section along the line VV which crosses the container 2 in FIG. 1 between the first portions 16. The peripheral edge 11 has no inner rib 31 and is substantially vertical, high in height, and has a smooth surface. The lower peripheral edge 26 of the lid 3 is also substantially vertical and tall, and its outer surface 39 is in close contact with the inner surface 36 of the container 2.
[0015]
6 to 8 are partial cross-sectional views of the container 2 and the lid 3 when the lid 3 is placed on the container 2 before closing the lid 3, and the positions of the cross sections of the container 2 and the lid 3 are shown in FIG. This is the same as the positions # 5 to # 5.
[0016]
In FIG. 6, the lower peripheral portion 26 of the lid 3, in the vicinity of the lower end 41, is in contact with the upper surface 33 of the inner rib 31 in the container 2 from above. When the lid 3 in this state is lowered as shown by the imaginary line, the peripheral portion 11 of the highly flexible and easily deformable container 2 pressed by the lower peripheral portion 26 having low flexibility and being difficult to deform is shown by the phantom line. FIG. 4 is a diagram in which the lower peripheral portion 26 of the lid 3 is elastically deformed outward, the lower peripheral portion 26 of the lid 3 fits into the groove 15, and the peripheral portion 11 is elastically returned to the original state, and the container 2 and the lid 3 are snap-engaged. State 3 is reached. In this state, the lower surface 34 of the inner rib 31 of the container 2 and the outer surface 39 of the lower peripheral portion 26 of the lid 3 are in close contact with each other, and the lid 3 is not easily removed.
[0017]
7 and 8, the peripheral wall portion 11 of the container 2 extends upward substantially vertically or slightly inward. The outer surface 39 of the lower peripheral portion 26 of the lid 3 is positioned obliquely above the peripheral wall portion 11 as shown in FIG. 7 or is adjacent to the upper portion of the peripheral wall portion 11 as shown in FIG. The difference in the positional relationship between the peripheral wall portion 11 and the lower peripheral portion 26 in FIGS. 7 and 8 is caused by the difference in height between the two portions 11 and 26. When the lid 3 is lowered as indicated by the imaginary line, the inner surface 36 of the peripheral portion 11 and the outer surface 39 of the lower peripheral portion 26 are in contact with each other, or the lower peripheral portion 26 is slightly deformed outward while the peripheral portion 11 is slightly deformed outward. Fits in the groove 15 and is in the state of FIGS.
[0018]
FIG. 9 is a partial side view of the container 1 with a lid, and the inner rib 31 is indicated by a chain line. In the lidded container 1 of FIG. 1 in which the lid 3 is closed in the same state as in FIG. 9, the finger is applied to the first portion 16 of the container 2 and the outer rib 24 of the lid 3 located immediately above the container, and When a force is applied from both sides in the directions of arrows 43 and 44, that is, to reduce the width of the lidded container 1, the first end portion 12 of the container 2 and the first portion 16 connected to the first portion 16 to which the force is applied are applied. And the second end portion 22 of the lid 3 engaged with the first end portion 12 is slightly downward, and the second end portion 22 is slightly upward, as indicated by an imaginary line. It is elastically deformed so as to face. Due to these deformations, the engagement between the inner rib 31 of the container 2 and the lower peripheral portion 26 of the lid 3 is released, and the lid 3 can be opened. When the container 2 and the lid 3 are in a closed state, the inner rib 31 of the container 2 and the portion 25 of the outer rib 24 of the lid 3 are substantially in the same horizontal plane, and substantially in the direction around the opening 9 of the container 2. It forms a continuous single line. The outer rib 24 of the lid 3 made of a hard material and having high rigidity includes a portion 41 of the outer rib 24 located at the second end portion 22 of the lid 3 and a portion 25 located immediately above the first portion 16 of the container 2. Are connected via a portion 43 having a gentle inclination, and the outer ribs 24 extend substantially linearly. When the outer rib 24 is pressed at the portion 25, the deformation is transmitted through the outer rib 24 and appears as a deformation of the second end portion 22 as shown by the phantom line in FIG. In the case of the container 2 made of one of the soft materials, the rigidity of the peripheral portion 11 forming the first end portion 12 is increased by the presence of the inner rib 12, and the deformation when the first portion 16 is pressed is changed via the inner rib 12. It appears as a deformation of the first end portion 12 such as an imaginary line. In addition, since the lid 3 is snap-engaged only at the first end portion 12 of the entire circumference of the container 2, the first and second end portions 12, 22 are only slightly deformed in the opposite direction to each other. It is easily removed from the container 2. Therefore, the container 2 and the lid 3 do not require a knob for opening the lid 3. Since the lid 3 is thus opened, the hook 5 provided on the container 2 in FIGS. 1 and 2 can be omitted if it is not necessary to suspend the container 2 with the lid.
[0019]
【The invention's effect】
Although the container with a lid according to the present invention depends on its size, the lid can be closed by pressing the container and the lid from above and below, and the container with the lid closed is pressed inward in the width direction. You can open the lid. Therefore, in the present invention, it is not necessary to provide a protrusion serving as a knob for opening the lid on the container or the lid.
[Brief description of the drawings]
