餐盒內折結構Inside folding structure of lunch box

本發明係關於摺疊容器的技術領域，特別係關於一種餐盒內折結構。The present invention relates to the technical field of folding containers, in particular to an inner folding structure of a lunch box.

目前市面上常見多種具備摺疊效果的飲水杯、餐盒、收納箱…等，各式用於承裝食品、收納物品或商品的容器，為在不使用時能夠縮小其體積以便於攜帶或收納，故以矽膠材質製成之可摺疊的容器已廣泛使用於各個領域中。At present, there are many kinds of drinking cups, lunch boxes, storage boxes, etc. with folding effect on the market. All kinds of containers are used to hold food, storage items or commodities. Therefore, foldable containers made of silicone material have been widely used in various fields.

其中，以能夠摺疊的飲水杯或食器最廣為人知，尤其在推廣環保的現今，許多人外出時會攜帶自己的環保杯或環保碗，為在使用完畢後能夠縮小體積以便於攜帶，因此，摺疊容器不僅會以軟質的材質製作，更會在容器的表面及內面環狀凹設摺疊槽，以讓容器能夠順利被摺疊。Among them, foldable drinking cups or food utensils are the most widely known, especially in today's promotion of environmental protection, many people will carry their own environmentally friendly cups or environmentally friendly bowls when going out, in order to reduce the size after use to facilitate carrying, therefore, foldable containers Not only will it be made of soft material, but a folding groove will be concave annularly on the surface and inner surface of the container, so that the container can be folded smoothly.

然而，一般的摺疊容器通常是在容器外表面凹設一圈摺疊槽，容器內面也凹設一圈摺疊槽，而摺疊容器凹設有摺疊槽的位置之結構相對較脆弱，當摺疊容器撐開使用時，摺疊容器凹設摺疊槽的位置相對容易變形，造成整體容器站立時較不穩固。However, the general folding container usually has a concave folding groove on the outer surface of the container, and a folding groove is also formed on the inner surface of the container, and the structure of the folding container is relatively fragile. When open for use, the position of the concave folding groove of the folded container is relatively easy to deform, which causes the overall container to be less stable when standing.

有鑑於此，確有必要提供一技術手段以解決摺疊容器撐開使用時站立較不穩固的問題。In view of this, it is indeed necessary to provide a technical means to solve the problem that the folding container is relatively unstable when it is opened and used.

請參閱圖1至圖3，當該周壁12呈現該撐張狀態Q1時，該周壁12沿著該撐力方面延伸，由於該周壁12的內面121與該橫平面X之間夾有該支撐角度θ，使該周壁12呈現傾斜的狀態。Please refer to FIGS. 1 to 3 , when the peripheral wall 12 is in the stretched state Q1 , the peripheral wall 12 extends along the supporting force, because the support is sandwiched between the inner surface 121 of the peripheral wall 12 and the lateral plane X At the angle θ, the peripheral wall 12 is inclined.

請參閱圖3，當使用者自該周壁12的開口14處朝向該底壁13施予壓力時，受力從該周壁12的開口14處沿著該撐力方向F朝向該底壁13傳遞，由於該周壁12的表面122沿著該撐力方向F筆直延伸，因次受力能夠順暢沿著該撐力方向F自該周壁12直接傳遞至該底壁13。Referring to FIG. 3, when the user applies pressure from the opening 14 of the peripheral wall 12 toward the bottom wall 13, the force is transmitted from the opening 14 of the peripheral wall 12 to the bottom wall 13 along the supporting force direction F, Since the surface 122 of the peripheral wall 12 extends straight along the supporting force direction F, the secondary force can be smoothly transmitted from the peripheral wall 12 to the bottom wall 13 along the supporting force direction F directly.

值得注意的是，由於該表面122平整沿著該撐力方向F延伸，因此該周壁12上的受力能夠順利沿著該延伸方向傳遞至該底壁13，進而大幅減少該周壁12的變形。下詳細說明周壁12不易變形的原因，各該摺疊槽15僅自該內面121凹設，使各該摺疊槽15內分別具有最接近該表面122的一脆弱點151，每一個該摺疊槽15內的脆弱點151相對各該摺疊槽15的其他位置更接近該表面122，使該該脆弱點151的位置形成該內面121與該表面122之間厚度最薄的區域，由於各該摺疊槽15是自該內面121凹設，因此當受力從該周壁12的開口14處開始傳遞而經過各該摺疊槽15時，各該摺疊槽15會從該脆弱點151的位置朝向該表面122彎曲，又因為該表面122沿著該撐力方向F筆直延伸，使該表面122呈現完整平面而不易變形，因此，該內面121自該脆弱點151朝向該表面122彎曲的形變量會在接近該表面122的位置被抵銷，進而達到減少該周壁12變形的效果。It is worth noting that since the surface 122 extends smoothly along the supporting force direction F, the force on the peripheral wall 12 can be smoothly transmitted to the bottom wall 13 along the extending direction, thereby greatly reducing the deformation of the peripheral wall 12 . The reason why the peripheral wall 12 is not easily deformed will be described in detail below. Each of the folding grooves 15 is only recessed from the inner surface 121, so that each folding groove 15 has a fragile point 151 closest to the surface 122. Each folding groove 15 The inner fragile point 151 is closer to the surface 122 than other positions of the folding grooves 15 , so that the position of the fragile point 151 forms the thinnest area between the inner surface 121 and the surface 122 . 15 is recessed from the inner surface 121 , so when the force is transmitted from the opening 14 of the peripheral wall 12 and passes through the folding grooves 15 , the folding grooves 15 will face the surface 122 from the position of the weak point 151 . Bending, and because the surface 122 extends straight along the support direction F, the surface 122 presents a complete plane and is not easily deformed. Therefore, the deformation of the inner surface 121 from the fragile point 151 toward the surface 122 will be close to The position of the surface 122 is offset, thereby reducing the deformation of the peripheral wall 12 .

由於本發明僅在該內面121凹設摺疊槽15，進而能夠保持該表面122的完整性，不僅讓周壁12的受力能夠沿著該撐力方向F完整傳遞至該底壁13，以讓更多受力能夠傳遞至該底壁13承受，並減少該周壁12所需承擔的受力，進而減少周壁12變形。再者，由於僅在該周壁12的內面121凹設該摺疊槽15，因此，能夠維持該表面122的完整性，使該表面122呈現完整平面而不易變形。Since the present invention only recesses the folding groove 15 on the inner surface 121, the integrity of the surface 122 can be maintained, and the force of the peripheral wall 12 can be completely transmitted to the bottom wall 13 along the supporting force direction F, so that the More force can be transmitted to the bottom wall 13 to bear and reduce the force that the peripheral wall 12 needs to bear, thereby reducing the deformation of the peripheral wall 12 . Furthermore, since the folding groove 15 is recessed only on the inner surface 121 of the peripheral wall 12 , the integrity of the surface 122 can be maintained, so that the surface 122 presents a complete plane and is not easily deformed.
