Description

sheet straw

The present invention relates to a sheet straw made of flexible sheet material.

Generally, widely used straws are configured in a cylindrical shape, and are made of resin, paper, metal, or the like. Straws made of resin or paper are often discarded after being used once, and especially disposable resin straws pose environmental problems such as marine pollution. Repetitive use of resin straws is conceivable, but it is expected that there will be hygiene problems and consumers will not accept the use of straws after washing.

On the other hand, in the case of paper straws, the manufacturing cost is higher than the current resin straws, and it is expected that the shift to paper straws will increase the burden on providers. In addition, in response to the environmental problems associated with resin straws, it has been considered to use metal straws after washing them, but this is expected to increase costs in terms of hygiene and washing work.

In recent years, the market for tapioca drinks and other edible granules that cannot be passed through normal straws has been expanding. For this reason, it is no longer possible to use only one type of straw, and it is becoming necessary for providers to prepare straws with different diameters according to their uses.

Under these circumstances, an environmental protection straw (Patent Document 1) is being considered that is reusable and the inside of the straw can be easily cleaned. The environmental protection straw has a top surface with a first side edge and a second side edge respectively formed on both sides, and a bottom surface with a third side edge and a fourth side edge respectively formed on both sides. A tube body formed with a hollow portion corresponding to an inner diameter by winding a sheet-like flexible member, at least one connecting portion formed corresponding to a first side edge of the upper surface, and the lower surface. and at least one assembly formed correspondingly to the fourth side edge, said assembly configured to engage said coupling portion to form said hollow for fluid passage.

This environmental protection straw has a structure in which a coupling portion formed on the first side edge and an assembly portion formed on the fourth side edge are engaged to form a hollow portion. It is unclear whether the engagement state between the connecting portion and the assembly portion can be reliably performed over the entire length of the straw. That is, when the hollow portion is formed by winding a sheet-like flexible member, it is considered that the flexible member is made of a relatively soft material. When engaging the joint portion of the first side edge of the flexible member with the fourth assembly portion, the joint portion and the assembly portion are engaged with each other at an intermediate portion of the entire length of the straw. It is expected that this will be done by pressing only from the In such a situation, it is expected that the hollow part will be crushed in the middle part of the straw.

In the specific structure of the connection part and the assembly part of the environmental protection straw, only the structure of inserting and engaging the convex part of the U-shaped cross section into the concave part of the U-shaped cross section is shown. Therefore, it is unclear whether or not the engagement structure can constitute a closed hollow portion, and no detailed disclosure is made on this point. Therefore, it is unclear whether or not it is possible to reliably construct the hollow portion of the straw in a state in which watertightness is ensured when the straw is composed of a sheet-like flexible member.

In the environmental protection straw, a diagram is drawn in which a sheet-like flexible member is spirally wound to form a hollow shape, but the method and position of joining are completely unknown, and the mouth part is not clear. It has a sharp shape and is dangerous. In addition, if you actually wind a rectangular sheet-like flexible member spirally and try to fix the connecting part at a suitable position for the straw, the number of turns of the mouth part and the mouth part will be different, so it will not be circular. It is conical rather than columnar. Further, detailed disclosure on this point is not made.

In addition, paper pack containers are sold with straws attached, but PET bottled beverages and canned beverages are rarely pre-attached with straws. One of the reasons for this is thought to be that the container allows the beverage to be drunk without a straw. Regarding PET bottled beverages, it is assumed that there will be a need to use straws, especially in nursing care settings, but there is a problem that if a cylindrical straw is attached to the container shape, it will come off during transportation and sales. , has not been able to meet the needs.

Utility Model Registration No. 3220336

FIG. 1(a) is a perspective view showing the overall shape of the sheet straw before being wound according to the first embodiment of the present invention, and FIG. 1(b) is a straw obtained by winding the sheet straw. It is the perspective view which showed the state which can be used. FIG. 2 is a plan view showing the basic shape of the sheet straw that is the first embodiment of the present invention. The basic shape of the sheet straw shown in FIG. 2 shows the basic shape of the sheet straw shown in FIG. ing.

The sheet straw 1 is made of a sheet material that does not emit harmful substances when in contact with beverages. , water-repellent paper, bamboo, biodegradable plastic, etc. are used. As for the performance of the sheet material itself, since it is wound to form a straw, it is flexible and has an appropriate repulsive force against bending. It is made of a material that can ensure durability.

In addition, when the sheet material is wound to form a straw and a beverage containing solid matter is sucked up, the inside of the straw becomes negative pressure. Therefore, when the sheet material is wound to form a straw, the overlapped portion of the sheet material has a repulsive force capable of overcoming the negative pressure and maintaining a watertight state. As such a sheet material, for example, if it is made of polypropylene resin, it is considered suitable that the thickness is 0.03 mm or more and 0.5 mm or less in consideration of ease of winding.

　In Fig. 2, the sheet straw 1 is composed of a straw body part 2 and a straw holding part 3. The straw body portion 2 and the straw holding portion 3 are made of one sheet material, and the straw holding portion 3 is formed continuously with the straw body portion 2 . The straw main body 2 is formed in a parallelogram surrounded by symbols A, B, C, and D. As shown in FIG. A triangle surrounded by symbols A, B, and E constitutes the straw holding portion 3 .

The side connecting the symbol A and the symbol D is the drinking mouth short side part 8 that constitutes the drinking mouth part of the straw, and the side connecting the symbol B and the symbol C constitutes the suction part that is inserted into the beverage of the straw. It is the short side portion 9 . The side connecting the reference characters C and D is the winding start long side portion 10a corresponding to the winding start portion for forming the straw body. A winding end long side portion 10b corresponding to a winding end portion in the case where the side connecting the reference numerals A and B constitutes the straw body. A straw main body 2 having a parallelogram as a whole is constituted by the mouthpiece short side 8, the suction short side 9, the winding start long side 10a, and the winding end long side 10b.

The angles formed by the sides A and B of the straw main body 2, that is, the end long side 10b and the sides B and C, that is, the suction short sides 9, are obtuse angles. The sides A and D, that is, the short side portion 8 of the mouthpiece, and the sides A and B, that is, the end long side portion 10b form an acute angle.

The height (PQ) of the parallelogram surrounded by symbols A, B, C, and D is the total length of the straw formed by the straw main body 2.

In addition, the length of the mouth short side 8 indicated by symbols A and D and the length of the suction short side 9 indicated by symbols B and C correspond to the maximum outer circumference length of the straw formed by the straw main body 2 . In practice, the optimal number of turns for stably configuring the straw differs depending on the repulsive force of the sheet. and the length of the suction short side 9 is determined.

Specifically, when the target diameter of the straw is 10 mm, and the number of turns that can stably hold the configuration of the straw from the thickness and repulsive force of the sheet is 2, the short side of the drinking mouth The length of 8 and the suction short side portion 9 is approximately 31.4 mm (peripheral length of diameter 10 mm)×2 turns=62.8 mm.

The straw holding portion 3 is a triangle formed by the side connecting the sign A and the sign B of the winding end long side portion 10b, the side connecting the sign A and the sign E, and the side connecting the sign B and the sign E. constitutes

The side connecting the code A and the code E is the straw holding part upper side 11, the side connecting the code B and the code E is the straw holding part lower side 12, and when these constitute the straw, the striped part of the straw appearance becomes. The angle between the upper side 11 of the straw holding portion and the extension line of the short side portion 8 of the drinking spout is approximately 45 degrees, and the extension of the short side portion 9 of the suction port with respect to the lower side 12 of the straw holding portion. The angle with the line is configured to be approximately 45 degrees. The angle of 45 degrees is the most stable, and the area of the sheet material is small so that the straw main body 2 can be fixed. A fixing piece 4, not shown in FIG. As shown in FIG. 1(a), the fixed piece 4 is integrally and continuously formed of the sheet material that constitutes the straw holding portion 3, and is composed of a fixed piece base portion 6 and a fixed piece tip portion 5. It is A plurality of insertion holes 7 into which the fixed piece distal end portion 5 can be inserted are formed in the fixed piece base portion 6 , and the fixed piece distal end portion 5 can be inserted into the insertion hole 7 . This structure serves to hold and fix the overall shape of the straw in the state shown in FIG.

The fixing piece 4 is preferably installed at a position where it does not soak in the beverage and does not touch the mouth. It is desirable to install it around (on the line of L3) lowered in the direction.

The sheet straw 1 configured in this way starts winding toward the winding end long side 10b with the winding start long side 10a of the straw main body 2 facing inward. At this time, it is very difficult to suck the end indicated by symbol C of the winding start long side 10a in the direction of symbol B and wind so that the short side 9 overlaps, and the winding start long side 10a It is easier to wind by turning the whole on the inside and winding toward the winding end long side portion 10b. In this case, the short side portion 8 of the mouthpiece and the short side portion 9 of the intake are spirally wound, and the respective ends are uneven. In order to correct these irregularities, the rolled straw body 2 is twisted to correct the winding angle so that the ends of the mouth short side 8 and the suction short side 9 are aligned. Then, the straw holding portion 3 covers the straw body portion 2 in a state in which the ends of the mouth short side portion 8 and the suction short side portion 9 are aligned.

After that, as shown in (1) and (2) of FIG. 3, the fixing piece distal end portion 5 of the fixing piece 4 is inserted into the insertion hole 7 at the position closest to the fixing piece base portion 6 and pulled out from the other insertion hole 7. As a result, the entire sheet straw 1 is fixed in a state in which the straw is configured. Further, if it is desired to strengthen the fixation, it is preferable to further insert the fixing piece distal end portion 5 protruding from the insertion hole 7 into another insertion hole 7 of the fixing piece base portion 6 as shown in (3) and (4) of FIG.

According to the sheet straw 1, when used as a straw, the straw body 2 and the straw holding part 3 can be wound to form a straw and be easily used. When the sheet straw 1 is used up, it can be used repeatedly by opening the wound straw body 2 and the straw holding part 3, washing the inner and outer surfaces of the sheet material, and drying it. can be done. Therefore, it poses less environmental problems than traditional disposable straws.

In addition, according to the sheet straw 1, the triangular straw holding portion 3 allows the winding end long side portion of the straw main body portion 2 in the rolled state to extend from the vicinity of the mouth short side portion 8 to the vicinity of the suction short side portion 9. It has a structure that it is pulled and fixed in the circumferential direction of the outer periphery of the straw over the entire length of 10b. Therefore, the straw main body 2 can be reliably held in a wound state, and the watertight state of the straw main body 2 can be maintained.

In this sheet straw 1, by winding the straw main body 2 so that the line connecting the reference characters E and F in FIG. The tubular hollow portion of the straw can be configured without In addition, when winding the straw body 2 so that the lines E and F overlap, the diameter of the straw can be changed by changing the number of turns.

For example, when the length of the short side portion 8 of the drinking spout is 62.8 mm, the relationship between the number of windings of the straw main body portion 2 and the diameter of the straw is as shown in Table 1 below.

As described above, according to the sheet straw 1, the diameter of the straw can be changed by changing the number of windings of the straw main body 2 so that the lines E and F substantially overlap each other. For example, when drinking beverages containing granular solids such as tapioca drinks, the diameter of the straw is larger than the size of tapioca, and in the case of beverages containing no solids such as tapioca, it is conventionally used. Can be used as a straw diameter.

Therefore, when selling beverages containing solids and beverages not containing solids at various beverage stores, there is no need to prepare straws with different diameters, and the sheet straw 1 alone can handle the different beverages. can do.

According to this sheet straw 1, when it is not used as a straw, it is entirely sheet-shaped and can be stacked and stored, so it can be stored in a narrower storage space than conventional cylindrical straws. Specifically, a cube of 168 mm × 145.49 mm × 240 mm containing 138 thick straws with an outer diameter of 14 mm and a total length of 210 mm, 564 narrow straws with an outer diameter of 7 mm and a total length of 210 mm, and 1938 of the sheet straws 1 It is possible to store 14 times the size of the straw with a large mouth and 3.4 times the size of the straw with the narrow mouth. Therefore, it is effective in terms of securing inventory space, making effective use of store space, and reducing product transportation costs.

According to this sheet straw 1, there is no need for a connecting member composed of a different material, there is no need for three-dimensional processing, and it can be constructed by die-cutting only one sheet material, so it can be manufactured at a low cost. is.

Due to the shape of the conventional cylindrical straw, there was little visible space for writing, and it was not realistic to use it for advertisements. On the other hand, according to the sheet straw 1 according to the present invention, there is more visible writing space than ordinary straws, and since it is made of a single sheet material without a three-dimensional structure, printing is easily possible. It has high utility value as an advertising space and can be expected to improve the profitability of the provider.

Next, with regard to the sheet straw 1 of the first embodiment of the present invention, the improved structure of the short side portion 8 of the mouthpiece will be described with reference to FIG. In the sheet straw 1, when the ends of the short side 8 of the mouthpiece and the short side 9 of the suction are aligned as shown in FIG. The sheet main body 2 is wound around the body, and it is expected that there will actually be individual differences in the way of winding. The details of the improvement of the short side 8 of the drinking mouth of the straw main body 2 will be described with reference to FIG.

FIG. 4(1) shows a state (X) of the sheet straw 1 in which the straw main body 2 is wound so that the lines E and F substantially overlap, and another state (X) in which the lines E and F do not overlap. It shows the state (Y) wound in a circle. At the end of the short side 8 of the drinking spout shown in (Y), the corner D of the straw main body 2 protrudes, which is expected to be unsuitable for use. In order to prevent such a problem, as shown in FIG. It is conceivable to form it in an arc shape. The height of the arc-shaped portion of the mouthpiece short side portion 8a is preferably about 10 to 20% of the length of the sides of the symbols A and D.

By forming the drinking mouth short side 8a of the straw main body 2 in a circular arc shape and forming the corners in a small diameter circular arc shape in this way, even if the winding method of the straw main body 2 is slightly different, As shown in (Z) and (W) of FIG. 4(2), the problem of the mouth portion can be eliminated. That is, in the case of (W) in FIG. 4 (2), the straw main body 2 is wound so that the lines E and F do not overlap. Since the tip of the tip is configured in an arc shape, it is possible to avoid damaging the user's lips or the like.

In addition, the short suction side portion 9 of the straw main body 2 is designed to scoop solids depending on the type of beverage (tapioca drink, shaved ice, etc.), as shown as the short suction side portion 9a in FIG. 4(3). A shape in which a part of the outer periphery protrudes is also conceivable. The suction short side portion 9a has a shape obtained by obliquely cutting a cylindrical shape in a state in which the symbols B and C substantially overlap each other, and has a shape capable of scooping up solids and the like.

Next, with regard to the sheet straw 1 of the first embodiment of the present invention, an improved structure for reducing differences in winding skills of users will be described with reference to FIG. Since the present invention is a winding straw that has not been common until now, in the winding method, the wound straw main body 2 is twisted in order to adjust the unevenness of the short side 8 of the drinking mouth and the short side 9 of the suction. In the winding method of correcting the winding angle so that the respective ends of the short side portion 8 of the drinking mouth and the short side portion 9 of the suction port are aligned, it is difficult for people who see it for the first time or when there is no guide. is assumed to be difficult. Therefore, the sheet straw 1a shown in FIG. 5 can be easily rolled by making the sheet material transparent or translucent, displaying a guideline L4 on the lines E and F in FIG. Become.

Next, a second embodiment of the present invention will be described with reference to FIG. The sheet straw 100 of FIG. 6(a) has a configuration in which parallelograms surrounded by symbols A, B, C, and D form rectangles. The sides A and B form a right angle with the sides B and C, and the sides adjacent to each side form a right angle.

In this sheet straw 100, the winding start long side portion 110a and the winding end long side portion 110b are kept parallel to each other toward the winding end long side portion 110b with the winding start long side portion 110a inside. The straw body portion 102 is wound to form a straw hollow portion. According to the sheet straw 100, when winding the straw main body 102, it is not necessary to twist the wound part, so that the winding operation can be performed regardless of the degree of experience of the person who performs the winding operation. can.

In contrast to the sheet straw 100, the sheet straw 200 has a shape in which the winding start long side portions 210a of symbols C and D bulge outward in an arc shape. By forming the winding start long side portion 210a in such a shape that it bulges outward in an arc shape, the straw body portion 202 can be easily wound.

In the sheet straw 100 and the sheet straw 200, the straw holding portion 103 and the straw holding portion 203 are continuously formed in the straw body portion 102 and the straw body portion 202, respectively. It is configured to hold the straw body portion 202 in a wound state.

According to the sheet straw 100, the winding operation of the straw main body 102 can be performed relatively easily without the need for work requiring experience such as twisting. Further, according to the sheet straw 200, the winding operation of the straw main body 202 can be easily performed by forming the winding start long side portion 210a in an arc shape. That is, the straw main body portion 202 has a winding start long side portion 210a formed in an arc shape, so that the width of the straw main body portion 202 is substantially increased, thereby facilitating the winding operation.

Next, a third embodiment of the present invention will be described with reference to FIG. The sheet straw of this embodiment has a ribbon shape, and its basic shape is shown in FIG. 7(a), and its practical structure is shown in FIG. 7(b).

The basic shape will be explained in FIG. 7(a). The sheet straw 300 is composed of a straw body portion 302 and a straw holding portion 303 . The straw main body 302 is composed of a winding start long side portion 310a, a winding end long side portion 310b, a mouthpiece short side portion 308, and a suction short side portion 309, and has a parallelogram overall shape. .

The straw holding portion 303 is formed continuously with the winding end long side portion 310 b of the straw body portion 302 . The straw holding portion 303 has a constant width in the range from the mouth short side portion 308 to the suction short side portion 309 of the straw main body portion 302 . Therefore, the straw body portion 302 and the straw holding portion 303 form a ribbon shape with a constant width.

The straw holding portion 3 of the sheet straw 1 of the first embodiment shown in FIG. 2 is configured in a triangular shape, but the straw holding portion 303 of the sheet straw 300 is configured in a ribbon shape having a constant width. The difference is that Therefore, when winding the sheet straw 300, the winding is started from the part C of the long side 310a at the beginning of the winding toward the part B, and the part of the straw main body 302 overlaps with the part of the long side 310a. The cylindrical shape of the straw main body portion 302 is held by the straw holding portion 303 which is continuous with 310b.

In the sheet straw 1 of the first embodiment, the width of the straw holding part 3 is different in the vicinity of the symbol A, the vicinity of the symbol E, and the vicinity of the symbol B, and the number of turns of the overlapping part when the straw is configured is different. ing. This results in the outer diameter of the constructed straw being different over the length of the straw. On the other hand, in the sheet straw 300, the straw holding portion 303 is configured to have a constant width, and the outer diameter does not change over the entire length of the straw on the line outside the winding end long side portion 310b. becomes. According to such a configuration, it is possible to form a straw by increasing the number of turns even if the material is soft or thin. However, since FIG. 7(a) does not show the structure corresponding to the fixing piece, a practical ribbon-type sheet straw 400 will be described with reference to FIG. 7(b).

In FIG. 7(b), the sheet straw 400 has the same basic shape as the sheet straw 300 described above. The sheet straw 400 has a winding start piece 420 at the beginning of the long side 410a at the beginning of winding and at the beginning of the short side 409 of suction. The winding start piece 420 is formed in a rectangular shape having a winding start upper side 420a parallel to the suction short side portion 409 and a winding start end side 420b. The winding start edge 420b is configured to have a predetermined width so as to facilitate the winding start operation of the straw main body.

A fixing piece 404 is formed continuously with the straw holding portion 403 in the vicinity of the short side portion 408 of the drinking spout of the straw holding portion 403 , and the fixing piece 404 is parallel to the short side portion 408 of the drinking spout. The fixed piece base portion 406 and the fixed piece distal end portion 405 are provided. A slit-shaped insertion hole 407 is formed in the fixed piece base 406, and the state of the straw is maintained by inserting the fixed piece tip 405 into the insertion hole 407 of the fixed piece base 406 in the state of forming the straw. .

According to this sheet straw 400, by winding the winding start piece 420 in the horizontal direction (extending direction of the suction short side portion 409), the difficulty of winding the ribbon type can be eliminated regardless of the skill of the user. That is, in the sheet straw 300, the portion indicated by reference character C has an acute-angled shape, and with this shape, the work when starting to wind the straw main body 302 is complicated, and it is expected that skill will be required. be. On the other hand, the winding start piece 420 of the sheet straw 400 has a rectangular shape as a whole, and the winding start piece 420 has a predetermined width. It can be done smoothly by comparison. In addition, regardless of the skill of the user, even the ribbon-shaped sheet straw 400 can be easily started to be wound.

In addition, the fixing piece 404 of the sheet straw 400 is configured such that the upper side thereof is recessed toward the suction short side 409 from the extension line of the drinking spout short side 408 . As a result, the sheet straw 400 can be wound and the shape of the straw is maintained by the fixing piece 404, and the fixing piece 404 can be configured so as not to touch the straw user's lips. Further, the fixed piece 404 is arranged so as not to be submerged in the beverage when used as a straw. The fixing piece 404 has the same function as the fixing piece 4 of the first embodiment in terms of holding the straw body portion 402 and the straw holding portion 403 in a wound state, and stabilizes the straw. can be fixed by

A fourth embodiment of the present invention will be described with reference to FIG. In the present sheet straw 500, the structure of the straw main body and the straw holding part is almost the same as that of the first embodiment. In the present sheet straw 500, the fixing means installed on the fixing piece 504 is different from that of the first embodiment. As shown in FIG. 8(1), a sheet-like magnet 510 is attached to the fixing piece tip 505 of the main fixing piece 504, and a sheet-like magnetic material 520 such as iron or nickel is attached to the fixing piece base 506. As shown in FIG. The position of the sheet-shaped magnetic body 520 attached to the fixed piece base 506 is such that, as shown in FIG. installed in overlapping positions. The attraction force between the sheet-shaped magnet 510 and the sheet-shaped magnetic body 520 is such that the fixed piece tip 505 does not come off from the fixed piece base 506 in a state in which the straw body and the straw holding portion are wound to form a straw. have power.

In use, attachment and detachment of the fixing piece 504 can be easily performed. Further, the structures of the fixing piece distal end portion 505 and the fixing piece base portion 506 of the fixing piece 504 can be simplified. Incidentally, instead of the sheet-shaped magnet 505 and the sheet-shaped magnetic body 506, it is also possible to use a magic tape, a snap button, a removable seal, or the like.

Regarding the fixing method, the same effect can be expected even if the positions of the sheet-like magnet 510 and the sheet-like magnetic material 520 are exchanged. , the sheet-shaped magnets 510 may overlap each other, and the magnetic force may cause difficulty in winding. Therefore, it is more preferable to attach the sheet-shaped magnet 510 to the fixed piece tip 505 and the sheet-shaped magnetic body 520 to the fixed piece base 506. .

In the fourth embodiment, as described above, even if the installation positions of the sheet-shaped magnet and the sheet-shaped magnetic body are exchanged, the straw main body and the straw holder can be fixed. Therefore, in the present embodiment, one of the sheet-shaped magnet and the sheet-shaped magnetic material is installed at the tip of the fixed piece of the fixed piece, and the other of the sheet-shaped magnet and the sheet-shaped magnetic material is installed at the base of the fixed piece of the fixed piece. It includes the concept of

A fifth embodiment of the present invention will be described with reference to FIG. The sheet straw 600 is composed of a straw body portion 602 and a straw holding portion 603 . The straw body portion 602 has substantially the same structure as the straw body of the first embodiment. The straw holding portion 603 has substantially the same structure as the straw holding portion of the first embodiment in that it is formed continuously with the straw body portion 602 . In this straw holding portion 603, the fixing piece 604 provided at the farthest position from the straw body portion 602 is different from that of the first embodiment. The fixing piece 604 is detachably attached to the tip of the straw holding portion 603 . A plurality of fixing projections 610a arranged in a straight line are provided at the end of the fixing piece base portion 606 of the fixing piece 604. As shown in FIG. A plurality of straight fixing holes 610b are provided at the tip of the straw holding portion 603. As shown in FIG.

The fixing protrusion 610a is configured to be fittable into the fixing hole 610b. Further, a fixing holder 610c is provided for fitting the fixing projection 610a into the fixing hole 610b and holding the fitted state between the fixing hole 610b and the fixing projection 610a.

The straw main body 602 and the straw holding part 603 of the sheet straw 600 are wound to form a straw, the fixed piece 604 is attached to the tip of the straw holding part 603, and the fixed piece tip 605 is attached to the fixed piece base. The state of the straw is maintained by inserting it into the insertion hole 607 of 606 .

According to this sheet straw 600, when the straw body part 602 and the straw holding part 603 are used for a certain period of time and the sheet member deteriorates, the straw body part 602 and the straw holding part 603 are replaced with new ones and fixed. Piece 604 can continue to be used.

A sixth embodiment of the present invention will be described with reference to FIG. FIG. 10(1) shows a beverage container 700, and the beverage container 700 is formed in a cylindrical shape. A synthetic resin film sheet 750, which is an example of a sheet material, is attached to the cylindrical outer peripheral portion of the beverage container 700, on which the name of the beverage, collective display, classification display, etc. are written. The film sheet 750 includes a sheet straw 750a. The film sheet 750 is continuously cut at a position corresponding to the outline of the sheet straw 750a as shown by the dotted line in FIG. uses the sheet straw 750a separated from the film sheet 750 for use. The shape of the sheet straw 750a is substantially the same as the sheet straw of the first embodiment.

By attaching this film sheet 750 to the beverage container 700, when the beverage in the beverage container 700 is to be drunk with a straw, the sheet straw 750a of the film sheet 750 can be cut off and the straw can be used simply and quickly. . Some beverage containers are equipped with a cylindrical straw wrapped in a packaging film, but the sheet straw 750a made of the film sheet 750 exposes the straw at the outer periphery of the beverage container and is bulky. never Therefore, it is possible to provide the sheet straw 750a even for general PET bottle beverages and the like, which have not been installed so far.

By the way, since a part of the straw constituted by the sheet straw 750a is inserted into the beverage, it is necessary to consider the contamination of the film sheet 750. For this reason, when using the sheet straw 750a, it is necessary to take care such as writing a warning to the user not to use the film sheet 750 in a defaced state. In addition, in order to prevent the sheet straw 750a from being soiled, it is conceivable that the film sheet 750 has a double structure.

A seventh embodiment of the present invention will be described with reference to FIG. The example of the sheet material shown in FIG. 11 is an example of the sheet material attached to the outer periphery of each cylindrical beverage container. A film sheet 800 shown in FIG. 11(1) shows a state in which the sheet-made straw 750a shown in FIG. In this film sheet 800, the fixing piece of the sheet straw 750a is long, and the shape of the entire sheet is inevitably large.

Therefore, the sheet straw 850a of the film sheet 810 shown in FIG. 11(2), which is another example of the sheet material, has a structure in which the fixed piece 860 has a shortened overall length. A hooking portion 860b having a chevron shape or a U shape is formed on the fixing piece tip portion 860a of the fixing piece 860. As shown in FIG. A slit-shaped insertion hole 870 is formed in the base side of the fixing piece 860, and the hooking portion 860b is hooked on the insertion hole 870, thereby retaining the shapes of the straw body and the straw fixing portion.

According to this film sheet 810, it is possible to form the sheet straw 850a even with a film sheet that is attached to a beverage container having a relatively short height. In addition, since the fixing piece 860 can be easily fixed simply by hooking the hook portion 860b onto the insertion hole 870, the fixing operation is facilitated.
