DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage container,
The present invention relates to a beverage container enclosing a beverage and a straw.

[0002]

2. Description of the Related Art As a beverage container, a container made of a flexible resin has been widely used. In this type of beverage container, when the upper part of the container is cut to form a liquid injection opening and a straw is inserted into the liquid injection opening, the beverage in the beverage container can be sucked and drunk by the straw. However, such a configuration requires labor for inserting a straw, and requires the straw to be prepared separately from the container, which is not convenient as a beverage container.

[0003] Therefore, a straw-enclosed beverage container 500 as shown in FIG. 13 has been proposed. The beverage container 500 has a main body constituting portion 502 for heat-sealing the four sides of the square to accommodate the beverage. The main body constituting portion 502 includes a front surface portion 505 and a rear surface portion 506 having the same shape as the front surface portion 505.
And a bottom gusset portion 503 that connects the front surface portion 505 and the back surface portion 506 to form a bottom portion. The bottom gusset part 503 is formed by folding inward in a V-shaped cross section by a bent part 503a, and is fused to the front part 505 and the back part 506 by heat sealing. By changing the heat seal width, a narrow neck portion 509 at which a liquid injection opening is to be formed by cutting is formed at one end of the uppermost portion of the main body constituting portion 502. Body configuration section 502
Inside, a straw 513 for drinking and drinking beverages is arranged.

[0004]

SUMMARY OF THE INVENTION Such a beverage container 5
00 has a flat shape as a whole, and it is necessary to increase the area of the front surface portion 505 and the back surface portion 506 in order to increase the filling amount of the beverage. In addition, such a beverage container 5
When the consumer opens the 00 at the neck 509, it is general that the heat-sealed portion near the neck is gripped by the fingers of both hands and torn in a direction crossing the neck 509 as indicated by an arrow A. . For example, pull your right hand forward with respect to the page.
By pulling the left hand to the back side with respect to the paper surface, an attempt is made to tear in the direction of arrow A by twisting the container. However, in such an opening method, tearing is difficult, and it is difficult to determine whether the opening trajectory on the front surface portion 505 side and the opening trajectory on the back surface portion 506 side are largely displaced, and tearing can be performed so as to reliably cross the neck. Depends on chance. If the opening locus shifts not in the neck but in the upper part of the figure, the opening becomes insufficient, and in the downward shift, the beverage unexpectedly leaks.

If the upper portion of the straw 513 is present in the neck portion 509 at the time of opening, the tearing locus of twisting the neck portion causes the tear locus to hit the upper portion of the straw. The disadvantage is that the tear is interrupted.

Further, when the straw is caught in the inside of the beverage by the front end of the straw catching on the inner wall of the front surface or the back surface, it is necessary to draw out the straw inside the beverage container from the opening portion after tearing. If the fingertip is dirty, the dirty fingertip may come into contact with the drinking mouth,
Not hygienic.

[0007] In addition, the unnecessary heat-sealed portion at the upper portion of the torn portion can suck and drink a beverage with a straw even if it is not completely separated from the container if the tearing is completed only at the neck portion. Unnecessary heat-sealed parts on the upper part touch the face or the like at the time of drinking and drinking, resulting in discomfort.

If scissors or the like are used, the neck portion 509 can be opened at a desired place, but it is troublesome to separately prepare scissors when carrying the beverage container 500 and opening it outdoors. Further, when opening the neck portion 509 using a tool such as scissors, if the upper part of the straw 519 is located inside the neck portion 509, avoid the straw and avoid the neck portion 509.
9 needs to be cut off from the front part 505 and the back part 506, and in some cases, the straw 513 in the ear part 509.
There is also a possibility that the upper part of the box may be cut with scissors.

Therefore, in the present invention, a beverage container having a straw disposed therein can be easily opened by a tearing force of a fingertip without using a tool such as scissors at an opening portion, and the upper portion of the straw can be opened. It is an object to provide a beverage container that does not interfere.

[0010]

In order to achieve the above object, the present invention provides a beverage container having a main body component for accommodating a beverage, and a drinking straw enclosed in the main body component together with the beverage. The main body constituting portion is joined by heat fusion between a front surface portion, a back surface portion having the same shape as the front surface portion, a bottom portion, and opposing edges of the front surface portion, the back surface portion, and the bottom portion. Section having a bent section and having a cross section V before enclosing the beverage
And a pair of gusset portions having a character shape, the front surface portion and the back surface portion move in a direction away from each other by deformation of the gusset portion, so that the beverage can be filled in the main body component portion, and The upper portion of the portion and the upper portion of the back portion form a neck portion that is narrower than the surface portion and the remaining portion of the back portion and extends in one direction, and the straw extends in the one direction from the neck portion toward the bottom portion. An extending and upper portion of the straw is positionable within the neck, and a notch is formed in an edge fusion portion of the neck to initiate tearing, and at least in a predetermined area corresponding to the notch. The front surface and the back surface are directly fused without the gusset portion, and a user grasps both sides of the notch on the front surface, the back surface, or any portion of the gusset portion. Pull in opposite directions along one direction Tearing direction teaching unit is provided for teaching the user that the tearing in Rukoto, 該首 unit so as to overcome the upper portion of the straw from the notch provides a beverage container can be opened.

Here, the upper portion of the front surface portion and the upper portion of the rear surface portion of the main body constituting portion are narrower than the remaining portions of the front surface portion and the rear surface portion, and the entire narrow width portion is formed in the predetermined region. The opposed edges are directly heat-sealed to each other without through the gusset portion to constitute the neck extending in the vertical direction, and the distance between the edges of the neck is equal to the bent portion of the gusset portion. It is preferable that the distance between the bending lines is equal to or smaller than the distance between the bending lines.

It is preferable that the straw is immovably fixed at or near the neck. In this case, in order to hold the straw in position with respect to the main body component, a region where the front surface portion and the back surface portion are directly fused to each other in the predetermined region corresponding to the notch is located in the neck portion. It preferably extends to the vicinity of the outer peripheral surface of the upper part of the straw. Alternatively, in order to hold the straw in position with respect to the main body constituting portion, an upper portion of the straw positioned in the neck portion and below the notch portion is locally at least one of the front surface portion and the back surface portion. It is preferable to be heat-sealed.

Further, it is preferable that the tear direction teaching section is constituted by printing the tear direction directly on any part of the front surface portion, the rear surface portion and the gusset portion. Alternatively, it is preferable that the tear direction teaching unit is configured by attaching or affixing a label or a seal indicating a tear direction to the front surface portion, the rear surface portion, or any portion of the gusset portion.

[0016]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A beverage container according to a first embodiment of the present invention and a manufacturing process thereof will be described with reference to FIGS. FIG. 1 shows a beverage container 1 filled with a beverage. The beverage container 1 has a main body component 2 for containing a beverage. The main body component 2 includes a bottom 3, a surface 5, and a surface 5.
, And a pair of gussets 7, 7 which form a side part by connecting the front part 5 and the back part 6. The gusset parts 7, 7 are formed by folding inward in a V-shaped cross section by the bent parts 7a, 7a (FIG. 2),
It is fused to the front surface portion 5 and the back surface portion 6 by heat sealing (thermal fusion) or the like. That is, the left and right edges of the front surface portion 5 and one edge of each of the gusset portions 7 and 7, and the left and right edges of the back surface portion 6 and the other edge of each of the gusset portions 7 and 7 are heat-sealed. To form a heat-sealed portion (heat-sealed portion) 8 having a width of 3 mm to 5 mm. In the state before filling the beverage, as shown in FIG.
Are positioned symmetrically parallel to each other with respect to the longitudinal center line X of the main body constituting portion 2.

The upper portion of the front surface portion 5 and the upper portion of the back surface portion 6 are narrower than the remaining portions of the front surface portion 5 and the back surface portion 6, and have a neck 9 extending in the vertical direction and a downward direction from the neck 9. It forms a gently sloping shoulder 10 which is shaped like a bottle neck. The neck 9 is arranged on the longitudinal center line X (FIG. 2) of the main body constituting portion 2, and the shoulders 10, 10 are symmetrical with respect to the center line X.

A gusset that connects the remaining portions except the neck 9 and the shoulder portion 10 of the back surface portion 6 and the remaining portion except the neck portion 9 and the shoulder portion 10 of the front surface portion 5 of the main body constituting portion 2 and forms a side portion The parts 7, 7 constitute the main filling part 11 for holding the beverage, and its cross section B is substantially square. Then, in order to form the bottom 3 shown in FIG. 1, as shown in FIG. 2, the lower edge of each of the front surface portion 5 and the back surface portion 6 and the lower edge of the gusset portions 7, 7 are formed by a pair of symmetrical slopes. It is constituted by edges 8b, 8b and a center edge 8c.

A straw 13 for drinking and drinking beverages is arranged in the main body component 2. The straw 13 is made of a material having a specific gravity lower than the specific gravity of the beverage filled in the main body constituting section 2, for example, a resin. The length L of the straw 13 is shorter than the height h after filling the beverage. Also, as shown in FIG.
The inner peripheral length of the liquid injection opening 4 is formed longer than the outer peripheral length of the straw 13. In the present embodiment, the straw 13
Is not long enough to reach the bottom 3 of the beverage container 1, but since the entire container has a flexible structure, the container also shrinks with drinking and drinking without leaving liquid in the container. Drinking and drinking is possible.

The front surface portion 5 and the back surface portion 6 are made of a laminated sheet of a flexible plastic material (resin film). As a specific example, a biaxially stretched polyethylene terephthalate film (PET) having a thickness of 12 microns
And a 15 micron thick biaxially oriented nylon film,
A three-layer laminated film of a linear low density polyethylene film having a thickness of 20 to 80 microns is used.

The gussets 7 are preferably made of a softer material than the front surface 5 and the back surface 6. As a specific material, a two-layer laminated film of a biaxially stretched nylon film having a thickness of 15 μm and a linear low-density polyethylene film having a thickness of 120 μm is used.

Here, the PET film has excellent heat resistance,
It is a material that does not lose its shape and is used to ensure dimensional stability in the bag making process. This material also has an advantage that processing at the time of molding by heat sealing is easy. The biaxially stretched nylon film has excellent toughness and is used to obtain a desired strength that does not make the beverage container 1 bulky and that can withstand transportation and handling. The linear low-density polyethylene film has thermal adhesiveness and is used for forming the beverage container 1 by heat sealing. This material also has toughness, although not as much as a biaxially stretched nylon film. In this specific example, since the front surface portion 5 and the back surface portion 6 are made of a transparent material, the position of the straw 13 disposed inside the main body constituting portion 2 can be confirmed from the outside. Since the PET film and the biaxially stretched nylon film have orientation, tearing can be easily performed by matching the strong stretching direction with a tear locus described later. Therefore, the thickness of the linear low-density polyethylene film having no orientation may be set to a thickness at which tearing can be performed. Further, as described above, the linear low-density polyethylene film is a material that is easily stretched and hard to tear because it has a certain degree of toughness. However, there is also an aspect that tearing is facilitated by laminating with a stretched film.

The heat seal portion 8 of the neck 9 is formed with a V-shaped notch 12 for starting the tearing of the neck 9. The gussets 7 also form the sides of the neck 9, but the gussets 7 do not exist in a predetermined amount region corresponding to the position of the notch 12, and the edges of the front surface 5 and the back surface 6 are not provided. Are directly fused to each other. The upper portion of the straw 13 extends and extends in the neck portion 9 and extends to a position higher than the position where the notch 12 is formed.

In the heat seal portion 8 near the neck 9, a consumer grips the notches 12 near the opposite sides and holds one hand in the same direction as the top of the neck and the other hand in the direction of the bottom. A tear direction teaching portion for teaching a consumer to tear in opposite directions is formed by printing, for example, by an arrow mark 15. For example, when the notch 12 is sandwiched and the fingers are gripped in the vicinity of the edge fusion portion with the fingers, and the left hand is pulled downward in FIG. 1 and the right hand is pulled upward in FIG. 1, tearing starts from the notch 12 as a starting point. The heat seal portion 8a above the neck portion 9 can be removed so as to get over the upper portion of the straw 13 and can be easily opened. When the heat seal portion 8a is removed and the beverage container 1 is opened, as shown in FIG. 3, a liquid injection opening 4 for discharging a beverage as a content is formed.

Next, the beverage container 1 according to the first embodiment will be described.
Will be described.

As shown in FIG. 4, a laminate sheet constituting the front surface portion 5, the gusset portions 7, 7 and the back surface portion 6 is laminated. Cutouts 7b, 7b are formed on the folded portions 7a, 7a side of the laminated sheet constituting the gussets 7, 7. Then, as shown in FIG. 5, the beverage container 1 is stacked on the laminate of the front surface portion 5, the gusset portions 7, 7 and the back surface portion 6.
The heat seal 8 having the shape of the main body component 2 is applied. At this time, the front surface portion 5 and the gusset portions 7 and 7 and the back surface portion 6 and the gusset portions 7 and 7 are fused, but a portion 8a between the bent portions 7a and 7a where no gusset portion 7 exists and a cutout portion 7b , 7b
The surface portion 5 and the back surface portion 6 are directly fused to each other. Further, as shown in FIG. 6, the laminate sheet is cut into the shape of the main body constituting portion 2 of the liquid container 1. FIG. 7 is a cross-sectional view of the surface portion 5, the gusset portions 7, 7, and the back surface portion 6 laminated and fused, and the portion where the gusset portions 7, 7 exist is as shown in FIG. The front part 5 and the gusset parts 7, 7 and the back part 6 and the gusset parts 7, 7 are fused to each other, and in the parts corresponding to the notches 7b, 7b, as shown in FIG. 5
And the back surface portion 6 are directly fused.

In the state before beverage filling of the beverage container 1 manufactured as described above (FIG. 2), the straw 13 is held between the bent portions 7a. Thereby, the straw 13 is held at a position where the gusset part 7 does not exist and the thickness of the main body constituting part 2 is thin, and when a large number of the main body constituting parts 2 are transported in a stacked manner, it is convenient without bulk.

When the beverage is filled in the beverage container 1, the beverage container 1 has a stable three-dimensional structure by opening the V-shaped gussets 7, 7 as shown in FIG. The bottom 3 of the beverage container 1 at the time of filling the beverage has a substantially square shape, and can be stably self-standing with the bottom 3 down and the neck 9 up.

Next, based on the information indicated by the arrow mark 15, when pulling in the opposite direction on the same straight line across the notch 12 and in the vertical direction parallel to the straw 13, the force acting on the front and back portions is obtained. However, in the same way as the concentration at the deepest part of the notch 12, the force can always be concentrated on the tip that is torn, and the tear locus reaches the heat seal part on the side opposite to the side where the notch 12 is formed. Sometimes, since the tearing force is concentrated at the head of the tearing locus, the tearing can be easily continued even in the heat seal portion on the opposite side, and the tearing can be reliably performed in the direction crossing the neck portion, and the heat at the upper portion of the neck portion 9 The seal portion 8a can be completely removed. Further, even if the tear locus between the front surface portion and the rear surface portion is slightly shifted, the force acting on the front surface portion and the rear surface portion is always concentrated on the head of the tear locus, as described above. In the heat seal portion on the front surface side and the heat seal portion on the back surface side opposite to the notch 12, tearing can be easily continued, and the heat seal portion 8a on the upper portion of the neck 9 can be completely removed. Can be. as a result,
At the time of drinking and drinking, the heat seal portion 8a at the upper part of the neck does not touch the face of the consumer.

Further, the gusset 7 does not exist in the portion where the tear occurs, and only the front surface 5 and the back surface 6 exist, so that the gusset 7 exists even in the portion where the tear occurs. Requires less force. Further, tearing in the opposite direction on the same straight line and in a direction parallel to the straw is a tear that always goes over the upper part of the straw 13, so that the upper part of the straw interferes with the tear locus. There is no. Therefore, the neck 9 can be easily opened so as to get over the upper part of the straw 13.

Next, a beverage container 100 according to a second embodiment of the present invention will be described with reference to FIG. Portions having the same configuration as in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the beverage container 100 according to the present embodiment, in the vicinity of the notch 12,
The heat seal 8 extends to near the outer peripheral surface of the upper portion of the straw 13 and forms a holding portion 8d for holding the straw 13. As a result, the heat-sealing portion 8a is removed, and the liquid injection opening 4 formed when the beverage container 1 is opened is in close contact with the outer periphery of the straw 13, and the straw 1 is held by the holding portion 8d.
3 is retained. Therefore, at the time of opening and after opening, the straw 13 can be maintained in a state of protruding from the liquid injection opening 4 without sinking into the main body constituting portion 2 of the liquid container 100.

In the structure in which the straw 13 is fixed to the main body constituting portion 2, the straw 13 is opened when the flexible container 10 is opened.
It functions as a zero skeleton, making it easier to hold the container with fingers. Therefore, opening can be performed more easily. Furthermore, by ensuring that the straw 13 is fixed to the main body constituting portion 2, the straw does not sink, and the work of gushing out the straw after unsealing becomes unnecessary.

Next, a beverage container 200 according to a third embodiment of the present invention will be described with reference to FIG. Portions having the same configuration as in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the beverage container 200 according to the present embodiment, a position above the straw 13 and below the notch 12 is joined to the surface portion 5 by a point seal portion 8e formed by heat fusion. Therefore, at the time of opening and after opening, the straw 13 does not sink into the main body constituting portion 2 of the liquid container 200,
The state of projecting from the liquid injection opening 4 can be maintained. In this embodiment, the point seal portion 8e is provided on the front surface portion 5 side, but may be provided on the back surface portion 6 side, or provided on both the front surface portion 5 side and the back surface portion 6 side. Is also good.

Next, a beverage container 300 according to a fourth embodiment of the present invention will be described with reference to FIG. Portions having the same configuration as in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In beverage container 300 according to the present embodiment, bellows 3
13A is provided. Bellows part 313A is straw 3
13 is formed at a position below the notch 12 and below the notch 12, and the straw 31
3 is a point seal portion 8 formed by heat sealing
It is joined to the surface part 5 by f. Therefore, at the time of opening and after opening, the straw 313 can be maintained in a state of protruding from the liquid injection opening 4 without sinking into the main body constituting portion 2 of the liquid container 300. The bellows part 313A is the other straw 31
Since more material is gathered than the part 3, the bellows 3
By performing heat sealing at the position of 13A, it is possible to prevent the straw 313 from being crushed by heat or pressure due to the formation of the point seal portion 8f. In addition, the bellows part 313A
The drinkability of the beverage is facilitated by the deformability of the beverage. In the present embodiment, the point seal portion 8e is provided on the front surface portion 5 side, but may be provided on the back surface portion 6 side, or may be provided on the front surface portion 5 side.
It may be provided on both the side and the back surface 6 side.

Next, a beverage container 400 according to a fifth embodiment of the present invention will be described with reference to FIGS. Portions having the same configuration as in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the present embodiment, the surface 4
Opposite edges are directly heat-sealed to each other in the entire upper narrow portion of the upper portion 05 and the lower portion 406 without the gusset portion. Therefore, the distance between the edges of the neck portion 409 (the distance between the outer edges of the heat sealing portion) is
7 and 407 are equal to or smaller than the distance between the bent portions 407a and 407a. In other words, in the neck portion 409, there is no side portion due to the gusset portions 407, 407, and the edges of the front surface portion 405 and the back surface portion 406 are directly fused to each other. In the present embodiment, the neck 409
Has a cap-like shape, in which a neck 409 is formed.
Is formed to be larger than the distance between the bent portions 407a, 407a of the gusset portions 407, 407, but this is an exceptional portion and merely a design shape. Further, similarly to the second embodiment, the notch 41 is used.
2, the heat seal 408 is connected to the straw 13
And a holding portion 408d for holding the straw 13 and extending to the vicinity of the outer peripheral surface of the upper portion. The upper portion of the straw 13 is positioned to extend into the neck portion 409 and extends to a position higher than the position where the notch 412 is formed.

When the opposite sides of the V notch 412 are grasped with the fingertips of both hands and pulled in the directions opposite to each other and in the direction in which the straw 13 extends based on the teaching by the tearing direction teaching section 15, the tearing starts at the notch 412. And the upper neck can be removed so as to get over the upper part of the straw 13. At this time, no gusset portion 407 exists at the portion where the tear occurs, and the surface portion 4
Since only the back portion 05 and the back surface portion 406 are present, the force required for the tearing can be reduced as compared with the case where the gusset 407 exists even at the portion where the tearing occurs. In addition, since the tearing direction is as described above, the tearing force is concentrated on the deepest part of the tear line, so that the tearing occurs easily and the straw 1
The neck 409 can be opened so as to get over the upper part of the third part 3. Upon opening, as shown in FIG. 12, a liquid injection opening 404 for pouring out a beverage as a content is formed.

As described above, in the vicinity of the notch 412, the heat seal 408 extends to the vicinity of the outer peripheral surface of the upper portion of the straw 13, and forms a holding portion 408d for holding the straw 13. Thereby, the heat sealing portion 4
08a is removed and the liquid injection opening 404 formed when the beverage container 400 is opened is in close contact with the outer periphery of the straw 13 as shown in FIG. 12, and the straw 13 is held by the holding portion 408d. Therefore, at the time of opening and after opening, the straw 13 is attached to the main component 40 of the liquid container 400.
2 can be maintained in a state of protruding from the liquid injection opening 404 without sinking.

The beverage container according to the present invention is not limited to the embodiment described above, and various modifications and improvements can be made within the scope described in the claims.

For example, in the above-described embodiment, the notch for starting the tearing of the neck is V-shaped, but may be I-shaped. The notches may be formed on the left and right sides of the neck edge.

In the above-described embodiment, the consumer grips the vicinity of both sides of the notch and places one hand in the direction of the top of the neck and the other hand in the direction of the bottom of the container on the same straight line in opposite directions. Although a tearing direction teaching section for teaching a consumer to tear at a distance is provided near the neck, the position where the teaching section is provided is not limited to the vicinity of the neck. Further, the tear direction teaching unit may be configured not only by printing but also by attaching a label teaching the tear direction or the like or attaching a seal to any part of the front surface, the back surface, or the gusset part. .

Furthermore, in the fifth embodiment, the area of the heat seal portion near the notch 412 is increased to form the straw holding portion 408d. Instead, the straw is replaced by the third straw shown in FIG. A point seal as in the above embodiment may be provided.

Further, in the fifth embodiment, a bellows portion may be provided on a straw and a point seal may be provided on the bellows portion as in the fourth embodiment shown in FIG.

Further, the straw may be provided with a protruding portion projecting perpendicularly to the longitudinal direction from the outer peripheral surface of the straw at an intermediate position in the longitudinal direction. If the straw is released from the neck for any reason, the straw may protrude from the liquid injection opening due to buoyancy.However, due to the protrusion projecting in the direction perpendicular to the longitudinal direction of the straw, the straw is somewhat opened. At the point when it protrudes from the neck, the projection engages the inner peripheral surface of the neck. This prevents the straw from protruding excessively from the upper liquid injection opening, and prevents the entire straw from being detached from the main body component to the outside.

Further, a notch may be partially formed in the gusset portion in the heat seal portion of the shoulder, and the front surface and the back surface may be directly heat-sealed at the edge of the shoulder.

Further, in the above-described embodiment, the front surface portion and the back surface portion are constituted by a laminate sheet. Here, in order to make tearing easier, Japanese Patent Application No. 2000-2529.
No. 96, as described in Japanese Patent Application No. 2000-252997, at a position corresponding to the notch, with respect to at least one of the front surface and the back surface of the laminate sheet, over the entire width of the neck, A perforation may be formed continuously through the notch except for at least one layer. According to such a configuration, the tear along the perforation can be performed, and the tear is further facilitated.

[0047]

According to the beverage container of the first aspect, since the tearing direction teaching portion is provided, the tearing direction teaching portion is provided on the same straight line across the notch based on the teaching, and is directed in opposite directions to each other and from the neck to the bottom. When pulling along one direction and tearing from the deepest part of the notch as a starting point, the force acting on the front surface and the rear surface is concentrated on the deepest part of the notch, and the force is always applied to the tip that is torn. Even when the tear locus reaches the heat seal portion on the side opposite to the side where the notch is formed, the tearing force is concentrated at the head of the tear locus, so even in the heat seal portion on the opposite side, The tearing can be easily continued, the tearing can be reliably performed in a direction crossing the neck, and the heat seal portion on the upper part of the neck can be completely removed.

Even if the tear trajectory between the front surface and the back surface is slightly shifted, the force acting on the front surface and the back surface is always concentrated at the head of the tear trajectory as described above. The tearing can be easily continued in each of the heat seal portion on the opposite surface portion side and the heat seal portion on the rear surface portion side opposite to the notch. Therefore, the heat seal portion at the upper part of the neck can be completely removed, and as a result, the heat seal part at the upper part of the neck does not touch the face of the consumer when drinking or drinking.

Further, since the direction in which the tearing force is applied does not interfere with the upper part of the straw, the straw does not hinder the tearing.

Further, since the gusset portion does not exist in the portion where the tear occurs, and only the front surface portion and the back surface portion exist, the force required for the tear is smaller than when the gusset exists even in the portion where the tear occurs. Less is needed.
