　従来から、ファーストフード店やコンビニエンスストアなどの多くの飲料の販売店では、プラスチック（合成樹脂）製や紙製のコップ等の飲料容器の開口部を、飲料容器用蓋で覆い、持ち運びの際に、その内部に収容されたジュースやコーヒーなどの飲料が開口部からこぼれ難いようにして販売している。 Conventionally, at many beverage stores such as fast food stores and convenience stores, the opening of beverage containers such as plastic (synthetic resin) and paper cups is covered with a beverage container lid to make it easier to carry. , are sold in such a way that beverages such as juice and coffee stored inside are difficult to spill from the opening.
　飲料容器の内部に収容された飲料を飲むには、単純に飲料容器用蓋を外して開口部から飲んでもよいが、飲料容器用蓋を外した際に、その内側に付着した飲料が飛び散り、飲む人の衣服等を汚してしまうおそれがある。 In order to drink the beverage stored inside the beverage container, the beverage container lid may be simply removed and the beverage may be drunk from the opening. There is a risk of staining the clothes of the drinker.
　そのため、飲料容器用蓋に、ストローの差込部を設け、付属のストローを差し込むことにより、飲料容器内部の飲料を飲み易くすることが多くなされている（特許文献１等参照）。 Therefore, it is often the case that the beverage container lid is provided with a straw insertion part and an attached straw is inserted into the beverage container to make the beverage inside the beverage container easier to drink (see Patent Document 1, etc.).
　しかしながら、昨今、プラスチックゴミによる海洋汚染問題等を発端に、脱プラスチックの世界的な流れが大きくなり、その一環として、プラスチックからなるストローを無くそうという流れも大きくなっている。 However, in recent years, the global trend to eliminate plastic has grown, triggered by the problem of marine pollution caused by plastic waste, and as part of this, there is also a growing trend to eliminate plastic straws.
　このような状況の下、市場では、ストローを無くし、飲料容器用蓋を外さなくても、飲料が飲み易い飲口を形成することができる飲料容器用蓋が求められている。 Under these circumstances, there is a demand in the market for a beverage container lid that eliminates the straw and can form a mouthpiece that makes it easy to drink without removing the beverage container lid.

　次に、図２～図４を用いて、本発明の実施形態に係る飲料容器用蓋の飲口形成方法について説明する。図２～図４は、本発明の実施形態に係る飲料容器用蓋の飲口形成方法を段階的に示す説明図である。 Next, a method for forming a mouthpiece for a beverage container lid according to an embodiment of the present invention will be described with reference to FIGS. 2 to 4. FIG. 2 to 4 are explanatory diagrams showing step by step the method of forming the mouthpiece of the lid for a beverage container according to the embodiment of the present invention.
　先ず、図２（ａ）及び図２（ｂ）～図３（ａ）及び図３（ｂ）に示すように、飲口形成用内側部位１１Ｂを、親指又は人差し指などの指Ｆ１で上から押し込むと、飲口形成用外側部位１１Ａと飲口形成用内側部位１１Ｂとの間が、折畳用低強度部１３の部分で谷折りとなる。 First, as shown in FIGS. 2(a) and 2(b) to 3(a) and 3(b), the mouthpiece forming inner portion 11B is pushed in from above with a finger F1 such as a thumb or index finger. Then, a valley fold is formed at the folding low-strength portion 13 between the mouthpiece-forming outer portion 11A and the mouthpiece-forming inner portion 11B.
　さらに、親指又は人差し指などの指Ｆ１で、飲口形成用外側部位１１Ａを、覆板部４の内側に向けて押し込むと、飲口形成用内側部位１１Ｂがさらに山折りされるとともに、飲口形成用外側部位１１Ａが山折用低強度部１４の部分でさらに谷折りされてさらに持ち上がる。 Further, when the mouthpiece forming outer portion 11A is pushed toward the inside of the cover plate portion 4 with a finger F1 such as a thumb or index finger, the mouthpiece forming inner portion 11B is further mountain-folded and the mouthpiece is formed. The outer side portion 11A is further valley-folded at the mountain-folding low-strength portion 14 and further lifted.
　そして、図４（ａ）及び図４（ｂ）に示すように、さらに、親指又は人差し指などの指Ｆ１で、飲口形成用外側部位１１Ａを、覆板部４の内側に向けて押し込むと、飲口形成用外側部位１１Ａと飲口形成用内側部位１１Ｂとが、山折りで折り畳まれるとともに、飲口形成用外側部位１１Ａの係止部１１ｃが、係合部である飲口１１０の縁部に係合し、飲口１１０が形成される。 Then, as shown in FIGS. 4(a) and 4(b), when the mouthpiece-forming outer portion 11A is pushed toward the inside of the cover plate portion 4 with a finger F1 such as a thumb or index finger, The mouthpiece-forming outer part 11A and the mouthpiece-forming inner part 11B are folded in a mountain fold, and the locking part 11c of the mouthpiece-forming outer part 11A is aligned with the edge of the mouthpiece 110, which is an engaging part. to form a spout 110 .
　次に、図５及び図６を用いて、本発明の実施形態に係る飲料容器用蓋１の設計条件について説明する。図５及び図６は、本発明の実施形態に係る飲料容器用蓋１の設計条件を例示した説明図である。 Next, design conditions for the beverage container lid 1 according to the embodiment of the present invention will be described with reference to FIGS. 5 and 6. FIG. FIG.5 and FIG.6 is explanatory drawing which illustrated the design conditions of the lid|cover 1 for beverage containers concerning embodiment of this invention.
　ここで、図５及び図６に例示した飲料容器用蓋１では、Ａは、繋部１１ｂの幅であり、Ｂは、繋部１１ａの幅であり、Ｃは、折畳用低強度部１３及び山折用低強度部１４のミシン目の間隔であり、Ｄは、折畳用低強度部１３及び山折用低強度部１４のミシン目の端部と飲口形成用線部の切込線部１２との間隔であり、Ｅは、折畳用低強度部１３と山折用低強度部１４との間の距離であり、Ｆは、折畳用低強度部１３と係止部１１ｃとの間の距離である。 Here, in the beverage container lid 1 illustrated in FIGS. 5 and 6, A is the width of the connecting portion 11b, B is the width of the connecting portion 11a, and C is the folding low-strength portion 13. and the interval between the perforations of the mountain fold low-strength portion 14, and D is the end of the perforation of the folding low-strength portion 13 and the mountain fold low-strength portion 14 and the cut line portion of the mouth forming line portion 12, E is the distance between the folding low-strength portion 13 and the mountain-folding low-strength portion 14, and F is the distance between the folding low-strength portion 13 and the locking portion 11c. is the distance of
　図５及び図６（ａ）に示した飲料容器用蓋１において、例えば、Ａを０．５ｍｍ、Ｂを０．７５ｍｍ、Ｃを０．５ｍｍ、Ｄを３ｍｍ、Ｅを８ｍｍ、Ｆを８ｍｍとすると、機能を満たした。 In the beverage container lid 1 shown in FIGS. Then it fulfilled the function.
　これに対し、図６（ｂ）に示した飲料容器用蓋１では、Ｅ＜Ｆとした。このように、Ｅ＜Ｆとした場合でも、機能を満たすことは可能であるが、係止部１１ｃを係合部である飲口１１０の縁部に係合させるには、次の条件を満たすことが重要である。 On the other hand, in the beverage container lid 1 shown in FIG. 6(b), E<F. Thus, even if E<F, the function can be satisfied, but the following conditions must be satisfied in order to engage the locking portion 11c with the edge of the mouthpiece 110, which is the engaging portion. This is very important.
　例えば、図６（ｂ）において、Ｅを１５ｍｍとした場合、Ｆ＝１．１３Ｅでは、Ｆ≒１６．９ｍｍとなり、折り畳んだ際、２ｍｍ程度の余りが出てしまうが、覆板部４の厚みなどを考慮すると、係止部１１ｃを係合部である飲口１１０の縁部に係合させることができ、機能は満たす。 For example, in FIG. 6B, when E is 15 mm, F=1.13E, F≈16.9 mm, and when folded, there is a remainder of about 2 mm, but the thickness of the cover plate part 4 In consideration of the above, the locking portion 11c can be engaged with the edge portion of the mouthpiece 110, which is the engaging portion, and the function is satisfied.
　すなわち、覆板部４の厚みをＸとすると、Ｘ≦Ｆ－Ｅ≦２（単位はｍｍ）の式を満たせば、Ｅ＜Ｆとした場合でも、機能を満たす。なお、この場合、０．５≦Ａ＜１．０（単位はｍｍ）の式（Ａの範囲）、及びＡ≧Ｃの式（Ｃの設定）も満たすとより好ましい。 That is, if the thickness of the cover plate portion 4 is X, and the expression X≤FE≤2 (in units of mm) is satisfied, the function is satisfied even when E<F. In this case, it is more preferable to satisfy the formula of 0.5≦A<1.0 (unit: mm) (range of A) and the formula of A≧C (setting of C).
