Description

雙斜口紙吸管及其成型方法Double oblique mouth paper straw and its forming method

本發明係關於一種吸管的技術領域，尤指一種容易刺穿飲料杯的紙吸管。The invention relates to the technical field of a straw, in particular to a paper straw that can easily pierce a beverage cup.

按，鑑於塑膠製品無法被大地消化，因而汙染並大肆破壞我們所居住環境，故紙製食品容器蔚為風潮，並為大家所提倡愛用紙製食品容器，以保護我們所居住的環境。In view of the fact that plastic products cannot be digested by the earth and thus pollute and destroy our living environment, paper food containers are becoming a trend, and we advocate the use of paper food containers to protect the environment in which we live.

然而，紙製容器具有強度不足的缺點，如圖5所示的市面上現有紙吸管4，為了能夠讓紙吸管4能夠刺穿飲料杯的杯口封膜，在該紙吸管4的一端經一裁刀裁切一刀而形成有單一斜邊41，然而該斜邊41所形成的穿刺端42乃為圓弧形而不夠尖銳，且若所使用的紙質硬度不夠的話，容易凹陷，而讓該紙吸管4較難刺穿飲料杯的杯口封膜來吸食飲料。However, paper containers have the disadvantage of insufficient strength. As shown in FIG. 5, the existing paper straws 4 on the market. In order to allow the paper straws 4 to pierce the sealing film of the beverage cup, one end of the paper straws 4 The cutter cuts a knife to form a single beveled edge 41. However, the piercing end 42 formed by the beveled edge 41 is arc-shaped and not sharp enough, and if the hardness of the paper used is not enough, it is easy to dent and make the paper It is difficult for the straw 4 to pierce the sealing film of the mouth of the beverage cup to suck the beverage.

因為，前述該紙吸管4存在有較難刺穿飲料杯的杯口封膜之問題點，故市面上出現了如圖6所示的另一款紙吸管5，由於該紙吸管5因其強度結構問題，僅能在其一端分別以裁刀裁切兩次方式來裁切出具鈍角θ的穿刺端51(共有二處穿刺端51)，若要裁切出較尖銳的銳角θ'的穿刺端51(圖6虛線表示處)，因紙質強度問題，當裁刀裁第一刀時會弱化該穿刺端51的紙質強度，當裁刀要裁第二刀時，裁刀就很容容易壓扁該穿刺端51，反而得到反效果，故現階段紙吸管銳角θ'的穿刺端51幾乎不可能由現有裁刀來裁切實現；雖然，具有鈍角θ的二穿刺端51的紙吸管5較前述紙吸管4容易刺穿飲料杯的杯口封膜，但整體而言，該紙吸管5的鈍角θ穿刺端51仍然存在較難刺穿飲料杯的杯口封膜之問題。Because the aforementioned paper straw 4 has the problem that it is difficult to pierce the sealing film of the cup opening of the beverage cup, another paper straw 5 as shown in FIG. 6 appears on the market, because the paper straw 5 is due to its strength For structural problems, only one end can be cut twice with a cutter to cut the piercing end 51 with an obtuse angle θ (there are two piercing ends 51), if it is necessary to cut the piercing end with a sharper acute angle θ' 51 (shown by the dotted line in Fig. 6), due to the paper strength problem, the paper strength of the piercing end 51 will be weakened when the cutter cuts the first knife. When the cutter cuts the second knife, the cutter is easy to squash The piercing end 51 has the opposite effect. Therefore, the piercing end 51 of the paper straw with an acute angle θ'is almost impossible to be cut by the existing cutter; although the paper straw 5 with two piercing ends 51 with an obtuse angle θ is more The paper straw 4 easily pierces the sealing film of the beverage cup, but overall, the obtuse angle θ piercing end 51 of the paper straw 5 still has the problem that it is difficult to pierce the sealing film of the beverage cup.

緣此，鑑於上述二款紙吸管較難刺穿飲料杯的杯口封膜之問題點，故本發明乃窮極心思開發出一種雙斜口紙吸管及其成型方法，故本發明之目的在於提供：可以製造出具尖銳穿刺端的紙吸管成型方法；本發明之另一目的在於提供：易刺破實用的環保紙吸管結構。Therefore, in view of the problem that the two paper straws are difficult to pierce the sealing film of the beverage cup, the present invention has developed a double oblique mouth paper straw and its forming method, so the purpose of the present invention is to provide : A paper straw forming method with sharp piercing ends can be manufactured; another object of the present invention is to provide a practical environmentally friendly paper straw structure that is easy to pierce.
