As a result, the straw-equipped beverage container 1 is in a state in which the upper portion of the paper material straw 50 protrudes obliquely upward through the through portions 13 and 14, as shown in FIG.

Next, the upper left surface 22 and the upper right surface 32 are pushed downward as indicated by arrow H shown in FIG. Then, the folding margin portion 28 and the folding margin portion 38 are folded into a triangular shape, and the vicinity of the penetrating portions 13 and 14 and the boundary portion 53 of the paper material straw 50 are deformed into a substantially flat shape, and the folding margin portion 26 and the folding margin portion 36 are deformed into a substantially flat shape. fold into a triangle. At this time, as shown in FIGS. 12 and 14, the back portion 52b, which is not bent and deformed, is deformed so as not to form a crease extending in the longitudinal direction. When the penetrating portions 13 and 14 of the paper material straw 50 are deformed into a substantially flat shape, the portion 52a of the paper material straw 50 is adhered to the portion 13a of the folding margin portion 26 and the portion 14a of the folding margin portion 36. As shown in FIG. Further, the portion 52b of the paper material straw 50 is adhered to the 13b portion of the folding margin portion 26 and the 14b portion of the folding margin portion 36. As shown in FIG. As a result, as shown in FIG. 13, the straw-equipped beverage container 1 is in a substantially flat state near the border 53 and near the penetrating portions 13 and 14 of the paper straw.

Next, as indicated by arrow I in FIG. 13, the triangular folding margin 28 and folding margin 38 are adhered to the left inner surface 23 and the right inner surface 33 . 13, the triangular folding margin 26 and folding margin 36 are woven together with the outer straw portion 52 so as to be in contact with the left front surface 21 and the right front surface 31. As shown in FIG. At this time, as shown in FIGS. 2 and 3, the paper material straw 50 is folded at the boundary portion 53, and the outer straw portion 52 along with the folding margin portions 26 and 36 extends downward along the left front surface 21 and the right front surface 31. I will turn. In this state, the air holes 15 and 16 formed in the upper ends of the left front surface 21 and the right front surface 31 are blocked by the lower straw portion 52 . Further, when the paper straw 50 is bent at the boundary portion 53 , the hole of the paper straw 50 is closed at the boundary portion 53 , preventing the beverage L from leaking out of the container body 11 . Thereby, as shown in FIGS. 2 and 3, the beverage container 1 with the straw in which the sealed space S is filled with the beverage L is obtained.

Finally, as shown in FIG. 1, the outer periphery of the left front surface 21 and the right front surface 31 of the beverage container 1 with a straw in which the sealed space S is filled with the beverage L is covered with a protective tape portion 60, and the entire outer straw portion 52 is covered with the protective tape portion 60. cover the Here, the protective tape portion 60 is strongly adhered to the container main body 11 at its upper portion and lightly adhered to the container main body 11 at its left and right sides and its lower portion in consideration of the operation during drinking, which will be described later. The outer straw portion 52 is simply folded and not fixed, but is held down and fixed by the protective tape 60 at this stage. This results in a straw-equipped beverage 2 as shown in FIG.

<Drinking motion>
Next, the drinking operation of the beverage product 2 with a straw having the above configuration will be described.

First, the protective tape portion 60 is peeled off from the straw-equipped beverage 2 in the normal state shown in FIG. 1, so that the lower straw portion 52 faces obliquely upward as shown in FIG. At this time, it is preferable to peel off the protective tape portion 60 from the bottom to the top as indicated by the arrow A shown in FIG. Specifically, the protective tape portion 60 is peeled off from below and lifted upward. Then, the force vector works efficiently, so that the outer straw part 52 can be lifted as shown in FIG. Especially in this embodiment, since the upper portion of the protective tape portion 60 is strongly adhered, and the left and right sides and the lower portion are lightly adhered, when the protective tape portion 60 is peeled off from below, the peeling stops at the upper portion. The outer straw portion 52 can be lifted efficiently. Then, when the state shown in FIG. 15 is reached, the air holes 15 and 16 are exposed and opened. However, in this state, although the folded state of the paper straw 50 is released, the vicinity of the penetrating portions 13 and 14 of the paper straw 50 and the vicinity of the boundary portion 53 remain substantially flat. and the outer straw part 52 hardly communicate with each other, and it is difficult to drink the beverage L filled in the sealed space S of the container body 11 through the paper material straw 50.例文帳に追加

Next, when the front part of the container body 11 is lightly pushed from the left and right as indicated by arrow K shown in FIG. Along with this deformation, the outer straw portion 52 is also deformed so as to spread smoothly in the front-rear direction and becomes a shape close to a circle. Here, the reason why the outer straw part 52 spreads smoothly in the front-rear direction is that the paper material straw 50 spreads up and down according to the deformation of the folding margins 26 and 36 as shown in FIG. This is because, as shown in FIG. 14, the portion 52b of the boundary portion 53 is not creases extending in the longitudinal direction. If the portion 52b were to have a crease extending in the lengthwise direction, as shown in FIG. 18, the straw 50 would be woven inwardly, and as a result, the straw 50 would remain substantially flat. end up As a result, as shown in FIG. 17, the inner straw portion 51 and the outer straw portion 52 are communicated with each other, and the paper material straw 50 forms a single tubular shape extending from the inside to the outside of the container body 11. The beverage L in 11 can be sucked out for drinking.

As described above, by using the beverage container 1 with a straw according to the present embodiment, the beverage L can be easily brought into a ready-to-drink state by the above two operations. That is, in the first operation, the protective tape portion 60 is peeled off and the outer straw portion 52 is lifted to open the air holes 15 and 16, and in the second operation, the container body 11 is pushed from the left and right sides to allow the substantially flat paper material straw 50 to penetrate. By smoothly opening the vicinity of the portions 13 and 14 and the vicinity of the boundary portion 53, the entire straw 50 can be stably formed into a cylindrical shape from the bottom to the tip of the container body 11. - 特許庁

<Effects of Embodiment>
As described above, the straw-equipped beverage container 1 of the present embodiment has the left box portion 20, the right box portion 30, and the connecting portion 40 connecting them. The left box portion 20 and the right box portion 30 are each formed by folding a common sheet 10 made of paper material, and the connecting portion 40 is also formed using the same sheet 10. . Then, the left box part 20 and the right box part 30 are butted against each other at a portion other than the connecting part 40, thereby constructing the box-shaped container main body 11 in which the beverage L is filled. At this time, the straw 50 made of paper material is integrally provided with the left box portion 20 or the right box portion 30 which are joined together as described above. The straw 50 also uses the sheet 10 common to the left box portion 20, the right box portion 30, and the connecting portion 40, and is formed into a tubular shape from the sheet 10. As shown in FIG.

As described above, in the beverage container 1 with a straw of the present embodiment, by using the straw 50 made of paper material instead of ordinary plastic, it is possible to reduce plastic waste, which is a worldwide problem. can. In particular, it is possible to integrally manufacture both the container body 11 for storing the beverage L and the straw 50 attached thereto from a single paper material sheet 10 . In this case, for example, by cutting out the container body 11 and the straw 50 from the large-sized synthetic paper P without waste, the consumption of the sheet 10 can be saved. At this time, if the length of the straw 50 and the length of the container body 11 are matched, the beverage container 1 with the straw can be cut out from a general rectangular synthetic paper P without waste (see FIGS. 4 and 5).

In addition, particularly in this embodiment, the paper material straws 50 are arranged between the inner straw portion 51 positioned inside the left box portion 20 and the right box portion 30 that are butted against each other, and the left and right box portions 20 and 30 that are against each other. and an outer straw portion 52 positioned outside. In a normal state, the inner straw portion 51 is provided along the inner peripheries of the wall surfaces 21 and 31 with the boundary portion 53 between the inner straw portion 51 and the outer straw portion 52 being bent. A portion 52 is provided along the outer periphery of the wall surfaces 21 and 31 (see FIG. 3).

As a result, in a normal state, the paper material straw 50 is bent at the boundary portion 53 so that the inner straw portion 51 and the outer straw portion 52 are not communicated with each other. It is possible to prevent the beverage L from leaking out of the container body 11 through the straw 50 (see FIG. 3). Further, by releasing the folded state of the paper material straw 50, the inner straw portion 51 and the outer straw portion 52 are communicated with each other, and the beverage L in the container body 11 can be sucked out through the straw 50 during drinking. state (see FIGS. 16 and 17). At this time, by folding the paper material straw 50 at the upper ends of the left box part 20 and the right box part 30, the boundary part 53 is positioned at the upper ends of the left box part 20 and the right box part 30. Therefore, the outer straw portion 52 can be bent downward to return to the normal state (see FIG. 3), and the outer straw portion 52 can be lifted to return to the drinking state (see FIG. 16).

In addition, particularly in this embodiment, at least one of the butted left box part 20 and right box part 30 has a through hole through which the paper material straw 50 having the inner straw part 51 and the outer straw part 52 penetrates in the length direction. It has parts 13 and 14 (see FIGS. 3, 4 and 10-17). Thereby, a structure in which the straw 50 penetrates the container body 11 can be easily obtained.

Here, if the paper material straw 50 is bent at the positions of the upper ends of the left box portion 20 and the right box portion 30 as in the present embodiment, the penetrating portions 13 and 14 are also bent at the left box portion 20 and the right box portion. 30 will be located near the upper end. When the outer straw portion 52 is lifted from the normal state in which the straw 50 is bent to be in a state for drinking, the penetrating portions 13 and 14 through which the paper material straw 50 penetrates are formed immediately after the outer straw portion 52 is lifted. 14 and 15), when the container body 11 is lightly pushed from the left and right (see arrow K in FIGS. 15 and 16), the openings of the penetrating portions 13 and 14 are opened. It deforms so as to expand and becomes a shape close to a circle (see FIGS. 12 and 16). As a result, the straw 50 forms a single tubular shape from the inside to the outside of the container body 11 (see FIG. 17), and can be stabilized.

At this time, since the paper material straw 50 is adhered to the peripheral portions of the openings of the penetrating portions 13 and 14, the outer straw portion 52 can be smoothly expanded when the container body 11 is pushed from both the left and right sides. Also, the portion 52b is not provided with a crease extending in the longitudinal direction (see FIG. 14). This is because if the portion 52b were creases extending in the longitudinal direction, the straw 50 would be woven inwardly, and as a result, the straw 50 would be maintained in a substantially flat shape (see FIG. 18). ).

In addition, in this embodiment, in particular, a protective tape portion 60 is attached to the outer periphery of the wall surfaces 21 and 31 so as to cover the outer straw portion 52 provided along the outer periphery of the wall surfaces 21 and 31 ( See Figure 1). As a result, the outer straw portion 52 can be kept clean in the normal state. Further, when the paper material straw 50 is configured to be folded at the positions of the upper ends of the left box portion 20 and the right box portion 30, the protective tape portion 60 can be peeled off from below and lifted upward to create an efficient vector of force. , the outer straw portion 52 can be lifted (see FIG. 15). At this time, if the upper part of the protective tape part 60 is strongly adhered, and the left and right sides and the lower part are lightly adhered, when the protective tape part 60 is peeled off from below, the peeling stops at the upper part, effectively The outer straw part 52 can be lifted.

Moreover, particularly in this embodiment, there are further air holes 15 and 16 passing through the inside and outside of the butted left box portion 20 and right box portion 30 (see FIGS. 4, 7, 15 and 16). . The air holes 15 and 16 are blocked by the outer straw portion 52 covered with the protective tape portion 60 with the protective tape portion 60 attached (see FIG. 1), while the protective tape portion 60 is at least partially peeled off. The outer straw part 52 is exposed by separating the outer straw part 52 in the closed state (see FIGS. 15 and 16). As a result, when the outer straw part 52 is lifted and changed from the normal state to the drinking state, the inside and outside of the container body 11 are communicated through the air holes 15 and 16, and the beverage L is smoothly fed through the straw 50. can drink to

In this embodiment, the left box portion 20 has a left front surface 21 facing the near side, an upper left surface 22 facing the upper side, a left inner surface 23 facing the back side, a left side surface 24 facing the left side, and a lower and a left bottom surface 25 facing the side (see FIGS. 1, 2, 4, 15 and 16). The right box portion 30 has a right front surface 31 facing the front, an upper right surface 32 facing the upper side, a right inner surface 33 facing the inner side, a right side 34 facing the right side, and a right bottom surface 35 facing the lower side. and (see FIGS. 1, 2, 4, 15 and 16). The connecting portion 40 connects the left inner surface 23 and the right inner surface 33, the right end portion of the left front surface 21 and the left end portion of the right front surface 31 constitute the abutting portion 12, and the paper material straw 50 serves as a wall surface. is provided integrally with the left front surface 21 or right front surface 31 along the left front surface 21 or right front surface 31 (see FIG. 2). As a result, in the straw-equipped beverage container 1 of the present embodiment, the paper material straw 50 can be provided integrally with the container body 11 with a simple structure.

In addition, particularly in this embodiment, the sealed space S formed inside the left box portion 20 and the right box portion 30 that are butted against each other is filled with the beverage L to obtain the beverage product 2 with the straw (FIGS. 3 and 4). 9 and FIG. 17). As a result, even if the beverage container 1 with a straw is discarded after the beverage L has been drunk, it is possible to prevent the amount of plastic waste from increasing.
