Description

The present invention relates to a container with a cap seal in which a cap seal is attached to various containers such as a beverage container.

2. Description of the Related Art Conventionally, a cap seal is used to protect the cap portion of a container containing beverages, seasonings, etc. and to ensure that the cap portion is unopened.
A horizontal perforation for opening is usually formed on the cap seal. A person who purchases a container with a cap seal, in which the cap seal is attached to the container, cuts it at the opening perforation and opens it.
In this respect, mischief that breaks the cap seal may occur. For example, even if there is no intention to purchase, there is a mischief in which the cap seal is rotated and broken at the perforation for opening, and then the cap seal is returned to the original state and the cap seal is disguised as unopened. Hereinafter, breaking the cap seal for such a mischievous purpose is referred to as “illegal opening”.

Patent Document 1 includes a container with a cap and a cap seal in which auxiliary perforations extending substantially parallel to the opening horizontal perforations are respectively formed, and the auxiliary perforations are formed above the opening horizontal perforations. In the cap seal, the opening horizontal perforation is located below the upper end of the body or the upper end of the body, and the auxiliary perforation is 3 mm or more above the lower end of the cap. A container with a cap seal is disclosed which is heat-shrink mounted at. With respect to such a container with a cap seal, when the cap seal is turned, the container is cut at the auxiliary perforation and an irregularly shaped cut piece is produced. By visually recognizing such a cut piece, it is possible to externally determine that the illegal opening has been made.

However, even if a cut piece is generated by the illegal opening, a customer or a sales clerk can perform it by a person who mischieves by removing the cut piece or by returning the cut piece to its original state. There may be a situation where it is impossible to determine at a glance whether or not there is an unauthorized opening. Further, in the case of over-the-counter sales in which many customers purchase many products, when the customers are required to register as quickly as possible (payment of products), the fact that the unauthorized opening has occurred may be overlooked. In other words, it may be difficult to find out the fact that the illegal opening has been made only by human eyes.

[First Embodiment]
<Cap seal>
The cap seal A of the present invention comprises a tubular body 1 which is heat-shrinkable in the circumferential direction, a reading area 2 provided in the tubular body 1, and an auxiliary breaking line 3 formed in the tubular body 1. , And the auxiliary breaking line 3 is arranged so that the virtual extension line of the auxiliary breaking line 3 intersects the edge of the reading area 2.
The tubular body 1 is formed of a heat-shrinkable film in a tubular shape. The cap seal A before being heat-shrinkably attached to the container can be opened in a cylindrical shape as shown in FIGS. 1 and 2. It should be noted that in the present invention, the “cap seal A” means a state before being attached to the container. Hereinafter, the cap seal before heat-shrinking will be identified by reference numeral A, and the cap seal after heat-shrinking the container will be identified by reference numeral B.
The cap seal A is opened in a tubular shape when it is attached to the container, but is folded in a flat shape as shown in FIGS. 3 to 5 during normal transportation and storage. In the illustrated example, the cap seal A is folded in a flat shape with the center portion in the width direction (corresponding to the circumferential direction of the tubular body 1) of the mechanical reading medium 21 described later as a fold.
In a realistic manufacturing process, the cap seal A is provided in the form of a continuous body in which a plurality of cap seals are continuously connected, and is folded into a flat shape. A cap seal A is obtained.

The heat-shrinkable film is a film that shrinks in the heat-shrinking direction when heated to the heat-shrinking temperature. The heat shrink temperature is, for example, 60°C to 120°C.
Examples of the heat-shrinkable film include a heat-shrinkable synthetic resin film, a nonwoven fabric, a foamed resin film, and a laminated film thereof. The laminated film may be a laminate of a layer having no heat shrinkability and a layer having heat shrinkability provided that the entire laminate has heat shrinkability. Preferably, a synthetic resin film or a synthetic resin laminated film is used as the heat-shrinkable film.
The material of the synthetic resin film or the synthetic resin laminated film is not particularly limited, and polyester resins such as polyethylene terephthalate and polylactic acid; olefin resins such as polypropylene and cyclic olefin; polystyrene and polystyrene such as styrene-butadiene copolymer. Resins; polyamide resins; one kind or a mixture of two or more kinds selected from thermoplastic resins such as vinyl chloride resins. The heat-shrinkable synthetic resin film may be composed of one resin layer, or may be composed of a plurality of different or different kinds of resin layers. Since it is relatively soft and easy to tear in the circumferential direction, it is preferable to use a film containing a polystyrene resin layer, and further a polystyrene resin film, or a laminated film in which a polystyrene resin layer and a polyester resin layer are laminated. It is more preferable to use.
The thickness of the heat-shrinkable film is not particularly limited, but for example, a film having a thickness of about 20 μm to 100 μm, and further about 20 μm to 80 μm can be used.

As the heat-shrinkable film, a film that mainly shrinks in the first direction is used, and a film that slightly shrinks or expands in the second direction may be used. The first direction means one direction in the plane of the film, and the second direction is a direction orthogonal to the first direction in the plane. As such a heat-shrinkable film, a uniaxially stretched or biaxially stretched film mainly stretched in the first direction can be used. The stretched film is oriented in at least the first direction and has a property of easily tearing in the first direction (tearability).
The heat shrinkage rate in the first direction (heat shrinkage direction) of the heat shrinkable film is not particularly limited, but is preferably 20% or more, more preferably 30% or more, and further preferably 40% or more. is there. The larger the heat shrinkage in the first direction is, the more preferable it is. However, the heat shrinkage in the first direction is theoretically less than 100% because the heat shrinkage naturally has a limit. When the heat-shrinkable film is a film that thermally changes in the second direction, the heat-shrinkage rate in the second direction is, for example, -3 to 15%, preferably 0 to 12%. The minus of the heat shrinkage rate means heat extension.
However, the heat shrinkage ratio is a ratio of the length of the film before heating (original length) and the length of the film after soaking in warm water at 85° C. for 10 seconds (length after soaking). , Is obtained by substituting in the following formula.
The heat shrinkage rate (%)=[{(original length in first direction or second direction)-(length after immersion in first direction or second direction)}/(first direction or second direction) Original length)]×100.

The film is rolled into a tubular shape so that the first direction (heat shrinking direction) of the heat-shrinkable film is the circumferential direction, and the first side end 11 is overlapped and adhered to the second side end 12. The tubular body 1 is formed by forming the seal portion 13. The seal portion 13 extends in a band shape in the axial direction of the tubular body 1.
The method of adhering the first side end 11 and the second side end 12 is not particularly limited, and examples include welding using a solvent and adhering using an adhesive.
The peripheral length of the tubular body 1 is, for example, more than the maximum peripheral length of the portion to be attached to the container×1 times the same×1.5 times or less, preferably the same×1.01 times to the same×1.3 times. And more preferably from the same x1.02 times to the same x1.15 times.

A mechanical reading medium 21 is provided in a partial area within the surface of the tubular body 1.
The mechanical reading medium 21 contains predetermined information, and the information can be read by an optical or electric reader. By providing the mechanical reading medium 21 on the tubular body 1, the reading area 2 is provided with mechanically readable information.
The optically readable information is converted into a one-dimensional or two-dimensional code according to a certain rule and replaced with an optically readable display (mechanical readable medium). Examples of such optical reading display include a bar code as shown in the figure, a matrix type two-dimensional code such as a QR code (registered trademark), a stack type two-dimensional code, etc., although not shown. By providing the display such as the bar code in a partial area of the cylindrical body 1, the mechanical reading medium 21 is provided in the area. The display as described above is generally formed by a printing method. The display is printed on the inner surface of the tubular body 1 (the back surface of the heat-shrinkable film) or the outer surface of the tubular body 1 (the front surface of the heat-shrinkable film). When the display is provided on the inner surface of the tubular body 1, it is preferable to use a heat-shrinkable film having excellent transparency in order to make the display visible.

Further, the electrically readable information is stored in the memory provided in the IC chip according to a certain rule. An electrically readable medium (mechanical readable medium) is composed of an IC chip in which information is stored in such a memory and an antenna section connected to the IC chip. By providing the IC chip and the antenna part in a partial area of the cylindrical body 1, the mechanical reading medium 21 is provided in the area. The IC chip and the antenna section are very thin and have a sheet-like shape, and are generally called as IC cards and are on the market. For example, by attaching a commercially available IC card to a partial area of the tubular body 1, the mechanical reading medium 21 is provided in that area. Alternatively, an antenna section is formed in a partial area of the tubular body 1 by a printing method or the like, and an IC chip is electrically connected and attached to the antenna section, so that the mechanical reading medium 21 is provided in the area. To be done. The IC chip and the antenna portion are provided on the inner surface of the tubular body 1 or the outer surface of the tubular body 1.

A reading area 2 is an area of the cylindrical body 1 in which the mechanical reading medium 21 is provided.
The position of the reading area 2 (in other words, the position where the mechanical reading medium 21 is provided) is not particularly limited as long as it is within the surface of the tubular body 1, but preferably the surface of the tubular body 1 excluding the seal portion 13. It is within. The seal portion 13 is a portion where the heat-shrinkable films are overlapped and adhered to each other, and cannot be easily broken. Therefore, when the area including the seal portion 13 is defined as the reading area 2, the reading area 2 is sufficiently opened at the time of unauthorized opening. It may not be able to break.
Further, the reading area 2 is formed in the tubular body 1 so that the upper edge of the reading area 2 coincides with or is located below the lower end of the cap portion of the container in the relationship after being attached to the container.
In the illustrated example, the reading region 2 is arranged in a part of the region below the peripheral unsealing auxiliary line in the tubular body 1.

The front view shape of the reading area 2 is not particularly limited, and may be a substantially rectangular shape, a substantially triangular shape, a substantially polygonal shape such as a substantially hexagonal shape, a substantially circular shape, a substantially elliptical shape, or the like. The substantially rectangular shape means a substantially rectangular shape or a substantially square shape. In the present invention, “substantially” in a plan view shape means a shape allowed in the technical field to which the present invention belongs. The “substantially” of the substantially rectangular shape, the substantially triangular shape, and the substantially polygonal shape in plan view is, for example, a shape in which a corner is chamfered, a shape in which a part of a side is slightly swollen or recessed, and a side is slightly curved. The shape is included. Further, the “approximately” of the substantially circular shape and the substantially elliptical shape in a plan view includes, for example, a shape in which a part of the circumference is slightly swollen or recessed, a shape in which a part of the circumference is slightly straight or diagonal. Be done.
The plan view shape of the reading area 2 is defined by the outer shape of the mechanical reading medium 21. The outer shape of the mechanical read medium 21 is a rough shape defined by connecting the outer edges of the medium. In FIG. 6, the outer shape of the reading area 2 in plan view is indicated by a chain line. For example, when the mechanical reading medium 21 is an optical reading display such as a bar code as shown in the drawing, the reading area 2 has a substantially rectangular shape in plan view. The outer shape of the optical reading display is defined by connecting the outer edges of the numeral portion and the bar portions.
When the mechanical reading medium 21 is an electrically readable medium such as an IC chip and an antenna portion (not shown), the plan view shape of the reading area 2 is a substantially rectangular shape, a substantially circular shape, or a substantially circular shape. For example, an elliptical shape. The outer shape of the medium including the IC chip and the antenna unit is usually defined by connecting the outer edges of the antenna unit.

When the mechanical reading medium 21 is a bar code as in the illustrated example, the bar code is arranged so that the longitudinal direction of the bar portion 21a of the bar code is parallel to the circumferential direction of the tubular body 1. However, the longitudinal direction of the bar portion 21a of the barcode may be arranged so as to be inclined with respect to the circumferential direction of the cylindrical body 1, or arranged so as to be parallel to the axial direction of the cylindrical body 1. It may have been done.

Note that the cylindrical body 1 may be provided with a design printing layer as needed (the design printing layer is not shown). The heat-shrinkable film may be transparent or non-transparent, but is designed on the back surface side of the film (the back surface of the heat-shrinkable film is the inner surface when the tubular body 1 is formed). When the printing layer is provided, a material having excellent transparency is used. In the present specification, transparent (colorless transparent or colored transparent) means that the total light transmittance is 70% or more, preferably 80% or more, more preferably 90% or more. However, the total light transmittance refers to a value measured by a measuring method based on JIS K 7361 (Testing method for total light transmittance of plastic-transparent material).

An auxiliary wire for breaking is formed on the cylindrical body 1.
The breakage auxiliary line is a line formed in the tubular body 1 to make the tubular body 1 easy to cut. Examples of the auxiliary line for breaking include a perforation line, a score line, and a half-cut line.
The perforation line is a line in which through-hole portions penetrating in the thickness direction of the heat-shrinkable film (cylindrical body 1) are intermittently continuous, like a stitch mark of a sewing needle. That is, the perforation line is a line formed by alternately connecting through-holes and non-through portions. The perforation line can be thought of as one line as a whole, in which a plurality of through-hole portions are arranged through the non-penetrating portion. The plan view shape of one through-hole portion of the perforation line includes a substantially circular shape or a substantially elliptical shape (pinhole shape), an elongated linear shape, a V shape, a Y shape, and the like. FIG. 6 illustrates a perforation line having a pinhole-shaped through hole portion.

The cut line is a cut line having a predetermined length that penetrates the heat-shrinkable film (cylindrical body 1) in the thickness direction. The plan view shape of the cut line is an elongated line shape, a V shape, or the like.
The perforation line of the perforation line and the cut line are common in that both penetrate in the thickness direction of the tubular body 1, but the length of the cut line is larger than the length of the through hole part of the perforation line. They differ in points. The length of the through-hole portion of the perforation line refers to the length in the direction in which the perforation line extends, and the length of the non-penetrating portion of the perforation line is the length of the two through-hole portions on both sides of the target non-penetrating portion. The shortest straight line length. The length of the score line refers to the straight length between both ends of the target score line.
The half-cut line is a line that is not penetrated in the thickness direction of the heat-shrinkable film (cylindrical body 1) and that has a continuous V-shaped cut portion.

Further, an unsealing auxiliary line is formed in the surface of the tubular body 1.
The unsealing auxiliary line is a line formed on the tubular body 1 so as to easily break the tubular body 1 when the cap seal B is opened.
In this respect, the breaking auxiliary line and the unsealing auxiliary line are common in that they are provided in order to facilitate the cutting of the tubular body 1, but the breaking auxiliary line is formed so as to break at the time of unauthorized opening. In contrast to the auxiliary line for opening, the opening auxiliary line is an auxiliary line that the purchaser of the container with a cap seal intends to use when opening the cap seal properly. In other words, the breaking auxiliary line is an auxiliary line formed for the purpose of discovering tampering, and the opening auxiliary line is an auxiliary line formed for the convenience of regular opening.
Examples of the auxiliary line for opening include the perforation line, the score line, and the half-cut line as described above.
One or a plurality of the unsealing auxiliary wires and the breaking auxiliary wires are provided independently of each other. It is preferable to use a perforation line as the unsealing auxiliary line, and it is preferable to use a perforation line or a score line or a combination of the perforation line and the score line as the breaking auxiliary line.
Specifically, the tubular body 1 is formed with an unsealing auxiliary wire 41 extending in the axial direction, an unsealing auxiliary wire 42 extending in the circumferential direction, and a breaking auxiliary wire 3. Hereinafter, the unsealing auxiliary wire 41 extending in the axial direction will be referred to as a "shaft unsealing auxiliary wire 41", and the unsealing auxiliary wire 42 extending in the circumferential direction will be referred to as a "circumferential unsealing auxiliary wire 42".

The shaft unsealing auxiliary wire 41 is extended in the axial direction of the tubular body 1 in a pair of left and right. The shaft unsealing auxiliary wire 41 may be extended so as to be inclined with respect to the axial direction, or may be extended parallel to the axial direction. In the illustrated example, the pair of shaft unsealing auxiliary wires 41 are provided so as to be inclined with respect to the axial direction so that the circumferential distance between the two wires becomes smaller as it goes downward. The shaft opening auxiliary wire 41 is formed between the upper edge and the lower edge of the tubular body 1. For example, the shaft unsealing auxiliary wire 41 may be formed from the upper edge to the lower edge of the tubular body 1, or may be formed from the upper edge of the tubular body 1 to a midway portion in the axial direction. Well, or may be formed from the upper portion (this upper portion does not include the upper edge of the tubular body 1 and is a portion apart from the upper edge downward) to the lower edge, or the tubular shape It may be formed from the upper part to the lower part of the body 1 (this lower part does not include the lower edge of the tubular body 1 but refers to a portion separated upward from the lower edge). In the illustrated example, the shaft unsealing auxiliary wire 41 is formed from the upper edge of the tubular body 1 to an intermediate portion in the axial direction.
Further, a case where a perforation line is used as the shaft opening auxiliary line 41 is illustrated.
The length of the through-hole portion of the shaft opening auxiliary wire 41 (perforation line) can be set appropriately, and is, for example, 0.5 mm to 2.5 mm, and the length of the non-penetrating portion of the shaft opening auxiliary wire 41 is It can be set as appropriate and is, for example, 0.5 mm to 2.5 mm.

The peripheral unsealing auxiliary wire 42 extends in the circumferential direction of the tubular body 1. The circumferential unsealing auxiliary line 42 may be extended to be inclined with respect to the circumferential direction, but preferably, the circumferential unsealing auxiliary line 42 is arranged in the circumferential direction of the tubular body 1 as in the illustrated example. It is extended in parallel.
The peripheral unsealing auxiliary line 42 is formed at a position spaced downward from the upper edge of the tubular body 1. The peripheral unsealing auxiliary line 42 may be formed in the entire circumferential direction, or may be formed in the circumferential direction except a part thereof. In the illustrated example, it is formed in the entire circumferential direction except for the peripheral unsealing auxiliary wire 42 and the region 19 sandwiched by the pair of shaft unsealing auxiliary wires 41, 41. Both ends of the peripheral unsealing auxiliary wire 42 are connected to the lower ends of the shaft unsealing auxiliary wires 41, respectively. Two regions 19 sandwiched by the pair of shaft-opening auxiliary wires 41 can be considered in the circumferential direction of the tubular body 1, but here, they are narrow regions. However, the peripheral unsealing auxiliary line 42 is not limited to being formed in the entire circumferential direction in the range excluding the region 19, and may be formed in a part in the circumferential direction in the range excluding the region 19.
An opening cut 43 is formed in the narrow region 19 as necessary. The unsealing notch 43 is connected to the lower ends of the pair of shaft unsealing auxiliary wires 41, 41, for example, and is formed on an extension of the circumferential unsealing auxiliary wire 42. The unsealing notch 43 is a notch having a predetermined length that penetrates in the thickness direction of the tubular body 1, similarly to the score line.
Further, a case where a perforation line is used as the peripheral unsealing auxiliary line 42 is shown.
The length of the through-hole portion of the peripheral opening auxiliary wire 42 (perforation line) can be set appropriately, and is, for example, 0.3 mm to 2.5 mm, and the length of the non-penetrating portion of the peripheral opening auxiliary wire 42 is It can be set as appropriate and is, for example, 0.5 mm to 2.8 mm.

The breakage auxiliary line 3 is arranged so as to cause breakage in the reading area 2 at the time of unauthorized opening.
That is, the breaking auxiliary line 3 is arranged in the plane of the tubular body 1 such that the virtual extension line of the breaking auxiliary line 3 intersects one edge of the reading area 2.
One edge of the reading area 2 refers to one of the sides forming the planar view shape of the reading area 2.
The virtual extension line may intersect at least one edge of the reading area 2, and may intersect, for example, two edges (if the virtual extension line is drawn long, for example, as shown in FIG. 6). , So that it intersects the two edges, such as the left and right edges of the reading area).
Specifically, the breaking auxiliary wire 3 extends, for example, in the circumferential direction of the tubular body 1. The breaking auxiliary line 3 may be extended to be inclined with respect to the circumferential direction, or may be extended parallel to the circumferential direction of the tubular body 1.
As the breaking auxiliary line 3, at least one selected from a perforation line, a score line and a half cut line is used. In the illustrated example, the breaking auxiliary line 3 is a combination of perforation lines and cut lines.
A perforation line is used as the first breaking auxiliary line 31, and a score line is used as the second breaking auxiliary line 32. Here, the breaking auxiliary line 3 includes a first breaking auxiliary line 31 and a second breaking auxiliary line 32.
The first auxiliary breaking line 31 extends in parallel with the circumferential direction of the tubular body 1, and the second auxiliary breaking line 32 also extends in parallel with the circumferential direction of the tubular body 1.

The first breaking auxiliary line 31 is arranged below the circumferential unsealing auxiliary line 42. The distance between the first breaking auxiliary line 31 and the circumferential unsealing auxiliary line 42 is not particularly limited, but if the breaking auxiliary line 3 is too far from the circumferential unsealing auxiliary line 42, the breaking auxiliary line during improper opening. 3 does not break, and there is a risk that breakage may occur in the peripheral unsealing auxiliary line 42. From this viewpoint, the distance H between the first breaking auxiliary wire 31 and the circumferential unsealing auxiliary wire 42 is preferably 30 mm or less, more preferably 20 mm or less, and even more preferably 15 mm or less. On the other hand, if the distance is too small, the breaking auxiliary line 3 and the circumferential unsealing auxiliary line 42 substantially overlap with each other, making it difficult to distinguish between the two. From this viewpoint, the distance H is preferably 1 mm or more, more preferably 3 mm or more, still more preferably 5 mm or more.
As shown in FIG. 3, the distance H between the first breaking auxiliary line 31 and the circumferential unsealing auxiliary line 42 is a linear length in the axial direction between the first breaking auxiliary line 31 and the circumferential unsealing auxiliary line 42. (Space between both lines in the axial direction). When the distance is not uniform in the circumferential direction, it means the maximum length.
The first breaking auxiliary line 31 extends in the circumferential direction from the left side of the reading area 2 to the right side of the reading area 2 except for the reading area 2. Therefore, the left end portion and the right end portion of the first breaking auxiliary line 31 are arranged near the left edge 2a and the right edge 2b of the reading area 2. For example, the first breaking auxiliary wire 31 is formed over the circumference of the tubular body 1×9/10 to the circumference of the tubular body 1×about 1/10.

The second breaking auxiliary lines 32 are formed on the left side and the right side of the reading area 2, for example. The second auxiliary breaking lines 32 are connected to the left end portion and the right end portion of the first auxiliary breaking line 31, respectively, and extend parallel to the circumferential direction of the tubular body 1 starting from the end portions. When the left end portion and the right end portion of the first breaking auxiliary line 31 are perforated holes of the perforation line, the second breaking auxiliary line 32 is formed to have one non-penetrating portion from each end. ing. The second breaking auxiliary line 32 is formed in a straight line. However, the second breaking auxiliary line 32 may be formed in a curved shape or a bent shape (the bent shape includes a dogleg shape and a zigzag shape).
The second breaking auxiliary line 32 has its end portion arranged at the edge of the reading area 2 or in the vicinity of the edge. In the illustrated example, the end portion of the second auxiliary breaking line 32 is arranged near the edge of the reading area 2. Here, in the present specification, the “vicinity” includes, for example, a case where the distance between a certain portion and another portion is 5 mm or less. Further, the fact that the end portion of the second breaking auxiliary line 32 is arranged in the vicinity of the edge of the reading area 2 means that the distance between the end portion of the second breaking auxiliary line 32 and the edge of the reading area 2 (here Includes a case where the straight line length between the end and the edge is 5 mm or less. Further, although the edge portion is arranged at the edge of the reading area 2, it means that the edge portion of the auxiliary breaking line 3 overlaps or slightly intersects with the edge of the reading area 2, although not particularly shown.

The second auxiliary line 32 for breaking is arranged so that its virtual extension line intersects the edge of the reading area 2. It should be noted that the breaking auxiliary line is not formed on the virtual extension line. In FIG. 6, a virtual extension line of the breaking auxiliary line 3 is shown by a chain double-dashed line. The virtual extension line is an imaginary straight line drawn from the end portion of the breaking auxiliary line 3 in parallel with the extending direction of the breaking auxiliary line 3. In addition, the term “cross” means that they are non-parallel to each other. In the illustrated example, the virtual extension line of the second auxiliary line for breaking 32 intersects the edge of the reading area 2 that extends in the axial direction.

Specifically, the virtual extension line from the second auxiliary line for breaking 32 on the left side whose end portion is arranged in the vicinity of the left edge 2a of the reading area 2 is a left edge 2a of the reading area 2 that extends in the axial direction. The middle part and the middle part of the right edge 2b are crossed (in other words, the virtual extension line passes from the left edge 2a to the right edge 2b through the plane of the reading area 2). An imaginary extension line from the second auxiliary line for breaking 32 on the right side whose end portion is arranged in the vicinity of the right edge 2b of the reading area 2 is a middle portion of the right edge 2b of the reading area 2 which extends in the axial direction. And the middle of the left edge 2a (in other words, the virtual extension line passes through the plane of the reading area 2 from the right edge 2b to the left edge 2a). The virtual extension line divides the reading area 2 into two areas. Although not shown, an imaginary extension line from the second auxiliary breaking line 32 on the left side, the end portion of which is arranged at the left edge 2a of the reading area 2, passes through the plane of the reading area 2 in the axial direction. A virtual extension line from the second auxiliary breaking line 32 on the right side, which intersects the middle portion of the extending right edge 2b and whose end is arranged at the right edge 2b of the reading area 2, passes through the plane of the reading area 2. And intersects the middle part of the left edge 2a extending in the axial direction.
Further, the angle of the virtual extension line with respect to the edge of the reading area 2 is not particularly limited, but one edge of the substantially rectangular reading area 2 is parallel to the axial direction and the auxiliary for the second breaking as in the illustrated example. When the line 32 is formed parallel to the circumferential direction of the tubular body 1, the angle is 90 degrees.
In the illustrated example, the virtual extension line is parallel to the longitudinal direction of the bar portion 21a.

The film cutting properties of the first breaking auxiliary line 31 and the circumferential unsealing auxiliary line 42 may be the same or one of them may be higher, but the first breaking auxiliary line 31 is a film better than the circumferential unsealing auxiliary line 42. High severability is preferred. High film cuttability means that the two auxiliary lines to be contrasted are formed on the same film in the same length and in the same direction, and when the film is torn along the auxiliary lines, the film is cut with a weak force. Say.
When the first breaking auxiliary line 31 is a perforation line, the length of the through hole portion can be set appropriately, and is, for example, 0.5 mm to 2.8 mm, and the non-penetrating portion of the first breaking auxiliary line 31. Can be appropriately set and is, for example, 0.3 mm to 2.5 mm. When the first auxiliary line for breaking 31 and the auxiliary line for unsealing 42 are both perforated lines, the method for constructing the first auxiliary line for breaking 31 having high film cutting property is as follows: (a) for first breaking The length of the through-hole portion of the auxiliary line 31 (perforation line) is made larger than the length of the through-hole portion of the circumferential unsealing auxiliary line 42, (b) the length of the non-penetrating portion of the first breaking auxiliary line 31 The length of the through hole portion of the first breaking auxiliary wire 31 is made larger than the length of the through hole portion of the peripheral opening auxiliary wire 42. (c) The length of the through hole portion of the first breaking auxiliary wire 31 is made smaller than the length of the non-penetrating portion of the peripheral opening auxiliary wire 42. In addition, the length of the non-penetrating portion of the first breaking auxiliary wire 31 may be made smaller than the length of the non-penetrating portion of the circumferential unsealing auxiliary wire 42.
The length of the second breaking auxiliary line 32 (cutting line) is not particularly limited, but is, for example, larger than the maximum length of the through-hole portion of the first breaking auxiliary line 31, preferably 3 mm or more, and It is preferably 4 mm or more, and more preferably 5 mm or more.

In the illustrated example, the shaft opening auxiliary line 41 is arranged such that its virtual extension line intersects the edge of the reading area 2. In the illustrated example, the virtual extension line of the shaft-opening auxiliary line 41 intersects the edges (upper edge and lower edge) of the reading area 2 that extend in the circumferential direction. It can be said that the shaft unsealing auxiliary wire 41 also serves as the breaking auxiliary wire.
The shaft unsealing auxiliary wire 41 of this illustrated example can be said to be a breaking auxiliary wire conceptually, but this shaft unsealing auxiliary wire 41 is expected to be utilized when the mounted cap seal is normally unsealed. Therefore, it is included in the category of the auxiliary line for opening here.

The shaft unsealing auxiliary wire 41, the circumferential unsealing auxiliary wire 42, and the breaking auxiliary wire 3 are, as will be described later, the circumferential unsealing auxiliary wire when the cap seal A is put on the cap portion of the container and heat-shrinkable. It is formed in the tubular body 1 so that a container with a cap seal in which 42 is arranged at a predetermined position of the container is obtained. Therefore, the size of the tubular body 1 and the specific arrangement of the shaft unsealing auxiliary wire 41, the circumferential unsealing auxiliary wire 42 and the breaking auxiliary wire 3 with respect to the tubular body 1 are determined by the shape and size of the cap portion of the container. It is designed appropriately according to the size and size.
It should be noted that the axial opening auxiliary line 41, the peripheral opening auxiliary line 42, and the breaking auxiliary line 3 are not formed in the plane of the reading area 2, and the reading area 2 remains as a film. Since the auxiliary line 41 for opening the shaft is not formed in the plane of the reading area 2, the information on the mechanical reading medium 21 can be read by the reader without any trouble.

The cap seal A can be obtained as follows, for example. After the tubular body 1 is manufactured using the heat-shrinkable film provided with the mechanical reading medium 21, the tubular body 1 is flatly folded with the center portion in the width direction of the mechanical reading medium 21 as a fold line. By engraving the shaft unsealing auxiliary wire 41, the circumferential unsealing auxiliary wire 42, and the breaking auxiliary wire 3 from the surface on one side of the flat tubular body 1 so as to penetrate the surface on the opposite side, Cap seal A can be obtained. In the cap seal A formed by such a manufacturing method, as shown in FIGS. 3 and 4, the shaft unsealing auxiliary wire 41, the circumferential unsealing auxiliary wire 42, and the breaking auxiliary wire 3 are mechanical reading media. It is formed symmetrically about 21.

The cap seal A can be attached to the cap portion of the container in a cylindrical shape and heat-shrinked to be attached to the cap portion. Alternatively, the cap seal A can be preformed and then put on the cap portion and heat-shrinked to cover the cap portion. You can also wear it. Preforming means that the cap seal A is deformed into a predetermined three-dimensional shape with an inner diameter such that it can be covered with the cap portion of the container. At the time of this preforming, a top plate may be attached to the cap seal A.
The specific structure of the preformed cap seal or the preformed cap seal with a ceiling plate is disclosed in, for example, Japanese Patent Application Laid-Open No. 2006-228246, so refer to it.

<Example of use of cap seal>
The cap seal A of the present invention is used by mounting it on various containers having a cap portion. By heat-shrinking and mounting the cap seal A on the mounted portion of the container including the cap portion, it is possible to protect the cap portion and prove that the container is unopened.

<Container>
As shown in FIG. 7, the container 6 has a body portion 61 having a storage space for storing contents, and a cap portion 62 attached to an end portion of the body portion 61.
The outer shape of the body portion 61 is not particularly limited as long as it is hollow so that the contents can be stored therein, and is substantially cylindrical, substantially elliptic, substantially polygonal such as substantially square or triangular, or substantially pyramidal. The substantially polygonal pyramid shape, the substantially gourd shape, the substantially daruma shape, and the three-dimensional shape in which these shapes are combined may be used. The "substantially" of the substantially polygonal columnar shape or the substantially polygonal pyramid shape includes a shape in which a corner is chamfered, a shape in which a part of a side is slightly swollen or recessed, a shape in which a side is slightly curved, and the like. .. Further, “substantially” in a substantially cylindrical shape, a substantially elliptical shape, a substantially gourd shape and a substantially daruma shape includes a shape in which a part of the arc is swollen or depressed, a shape in which a part of the arc is a straight line or a diagonal line, and the like. Be done.
Further, the outer shape of the body portion 61 may be a straight body shape or may not be a straight body shape. The straight body shape is a shape whose peripheral length does not change in the axial direction.

The body portion 61 in the illustrated example has a combined three-dimensional shape in which substantially cylindrical portions having different diameters are connected in the axial direction. Therefore, the body portion 61 in the illustrated example is not a straight body shape.
Specifically, the body portion 61 in the illustrated example connects the first portion 611 arranged on the lower side, the second portion 612 arranged on the upper side, and the first portion 611 and the second portion 612. And an intermediate portion 613. The outer shapes of the first portion 611 and the second portion 612 are both substantially columnar (the shape of the body is straight and the cross-sectional outer shape of the plane orthogonal to the axial direction is substantially circular), but the circumference of the second portion 612 is long. Is smaller than the circumference of the first portion 611. The peripheral length of the intermediate portion 613 is gradually reduced as it goes upward (the shape is not a straight body and the cross-sectional outer shape is substantially circular in a plane orthogonal to the axial direction).

The body portion 61 includes a bottom surface portion 63, and the container 6 can be self-standing on the bottom surface portion 63. The contents stored in the body 61 are not particularly limited, and examples thereof include alcohols, water, milk, drinks such as coffee, soy sauce, liquid seasoning such as soup stock, granular seasoning, shampoo, body soap, and the like. Examples include sanitary products.

A spout is opened at the upper end of the body 61 (the second portion 612 of the body 61). The spout communicates with the storage space of the body 61. To open and close this spout, a cap portion 62 is detachably attached to the upper end portion of the body portion 61. The cap portion 62 in the illustrated example is screwed onto the outside of the body portion 61 by a screw action.
As the outer shape of the cap portion 62, various shapes as exemplified in the body portion 61 can be adopted. The outer shape of the cap portion 62 may be a straight body shape or may not be a straight body shape. The cap portion 62 may be provided with accessories such as a tube portion and a pump portion for pouring out the contents (not shown).
The outer shape of the cap portion 62 in the illustrated example is a substantially cylindrical shape and a straight body shape. An upper surface 621 of the cap portion 62 of the illustrated example which is attached to the body portion 61 by a screw action and does not include the above-mentioned accessory is closed. A female screw portion is formed on the inner peripheral surface of the cap portion 62, and a corresponding male screw portion is formed on the outer peripheral surface of the upper end portion of the body portion 61.
The cap portion 62 can be attached to the body portion 61 by rotating the cap portion 62 in the opening direction and coming off the body portion 61, and by rotating the cap portion 62 in the closing direction. The opening direction of the cap portion 62 in the illustrated example is counterclockwise when viewed from above. However, the opening direction may be clockwise.

The peripheral length of the cap portion 62 is not particularly limited, but if it is too small, it may not break at the first and second auxiliary lines 32 for breaking at the time of unauthorized opening, and thus is, for example, 50 mm or more, and preferably. It is 60 mm or more. The upper limit of the circumferential length of the cap portion 62 is not particularly limited, but is generally 50 cm or less, and preferably 40 cm or less, in a realistic numerical value. When the circumferential length of the cap portion 62 is not constant in the axial direction (for example, when the cap portion 62 is not in the shape of a straight body), the circumferential length of the cap portion 62 means the maximum circumferential length thereof. To do. The height of the cap portion 62 (the length of the cap portion 62 in the axial direction) is not particularly limited and is, for example, 5 mm to 10 cm.
The circumference of the body 61 is not particularly limited, and may be the same as the circumference of the cap 62, or may be smaller or larger than the circumference of the cap 62.
In the container 6 in the illustrated example, the circumferential length of the cap portion 62 and the circumferential length of the second portion 612 of the body portion 61 to which the cap portion 62 is attached are substantially the same. In other words, the outer shape of the cap portion 62 and the second portion 612 is a straight body shape.
Further, the materials of the body portion 61 and the cap portion 62 are not particularly limited, and independently include glass, synthetic resin, metal, pottery, and the like.

<Container with cap seal>
As shown in FIGS. 8 and 9, the container C with a cap seal includes a container 6 having a cap portion 62, and a cap seal B heat-shrinkably attached to an attachment site of the container 6 including the cap portion 62. Have. The attachment site is other than the cap portion 62 and the cap portion (a part or all of the body portion 61), and the cap seal B is attached across the cap portion 62 and the portion other than the cap portion.
In the container C with a cap seal, the breaking auxiliary wire 3 corresponds to the body portion 61 of the container 6, the shaft opening auxiliary wire 41 corresponds to the cap portion 62, and the circumferential opening auxiliary wire 42 is the cap portion. The cap seal B is attached so as to correspond to the lower end of 62 or the vicinity of the upper side or the lower side of the lower end.
Regarding the mounting position in the relationship between the reading area 2 and the cap portion 62, the cap seal B is mounted so that the upper edge of the reading area 2 is aligned with or below the lower end of the cap portion 62. It is preferable that the reading area 2 is mounted so that the upper edge of the reading area 2 is located within a predetermined range below the lower end of the cap portion 62. The predetermined range is preferably a range of 1 mm to 30 mm below the lower end of the cap portion 62, more preferably 3 mm to 20 mm, further preferably 5 mm to 15 mm.

Regarding the mounting position in the relationship between the breaking auxiliary wire 3 and the cap portion 62, the cap seal B is mounted so that the breaking auxiliary wire 3 coincides with or is located below the lower end of the cap portion 62. it is preferable that the it is not more preferable that is mounted so that the broken auxiliary line 3 located within a predetermined range below the lower end of the cap portion 62. The predetermined range is preferably a range of 1 mm to 30 mm below the lower end of the cap portion 62, more preferably 3 mm to 20 mm, further preferably 5 mm to 15 mm.
Further, the cap seal B is generally in close contact with the outer surface of the mounting portion of the container 6 as a whole. Further, the upper end portion of the cap seal B is bent so as to be in close contact with the upper surface 621 of the cap portion 62. However, the cap seal B may be attached so that the upper end portion of the cap seal B is in close contact with the outer peripheral surface of the cap portion 62 (without bending on the upper surface of the cap portion 62).

The container C with a cap seal is obtained by mounting the cap seal A or the preformed cap seal on the mounting site including the cap portion 62 of the container 6.
Specifically, a cap seal A (or a preformed cap seal) is placed on the upper portion of the cap portion 62 of the container 6 and the second portion of the body portion 61. At this time, the peripheral unsealing auxiliary wire 42 is aligned and covered so as to correspond to the lower end of the cap portion 62 or the vicinity thereof. Then, by heating the cap seal A to the heat shrinking temperature, the container C with a cap seal is obtained. That is, when the cap seal A covering the mounting portion including the cap portion 62 is heated to, for example, 60° C. to 120° C., the tubular body 1 is thermally contracted in the circumferential direction and adheres tightly to the container 6, as shown in FIGS. A container C with a cap seal as shown in is obtained.

After the cap seal A is mounted on the container 6, the cap seal A undergoes a relatively large dimensional deformation in the circumferential direction, while the dimensional change in the axial direction is relatively small or substantially does not change in the axial direction. This depends on the heat shrinkage rate of the heat shrinkable film forming the tubular body 1. The thermal contraction rate of the cap seal B at the time of mounting is [{circumferential length of the cap seal A (cylindrical body 1) before thermal contraction-circumferential length of the mounting site of the container 6}/cap seal A before thermal contraction Perimeter of tubular body 1)] x 100.

After the cap seal A is attached to the container 6, the cap seal A has a relatively large diameter reduction in the circumferential direction, so that the perforation lines (the circumferential opening auxiliary line 42 and the first breaking auxiliary line 31 extending in the circumferential direction) can be reduced. The length of the through-hole portion and the length of the non-penetrating portion, the length of the cut line (the second auxiliary breaking line 32 extending in the circumferential direction), and the like depend on the thermal contraction rate when the cap seal B is attached. Becomes smaller accordingly. The amount of change in the length of the through hole of the perforation line of the cap seal A before heat shrinkage (how much the length becomes smaller after heat shrinkage) varies depending on the heat shrinkage rate of the cap seal B, Although it cannot be unconditionally determined, generally, the lower limit value of the amount of change in the length of the cap seal B after heat-shrinking attachment is 0.5 times, and the upper limit value thereof is less than 1 time. For example, when the length of the through-hole portion of the perforation line is 0.5 mm to 2.5 mm, the lower limit value of the length of the through-hole portion is 0.5 mm×0.5 times after the heat-shrink installation. As described above, the upper limit of the length may be less than 2.5 mm×1. Preferably, the amount of change in the length of the cap seal B after heat-shrink mounting is 0.6 times to 0.95 times. In this case, the length of the through hole portion of the perforation line after the heat shrinkage may be the lower limit value before heat shrinkage x 0.6 times to the upper limit value x 0.95. The lengths of the through-hole portion and the non-penetrating portion of the perforation line extending in the axial direction are preferably substantially the same before and after thermal contraction.

<Use of container with cap seal>
When the container C with a cap seal is normally opened, the upper end of the region 19 sandwiched between the pair of shaft opening auxiliary wires 41 is pinched with a finger, and the shaft opening auxiliary wire 41 is used to make a cap seal B. The area 19 is cut out of the upper part of the. Since the opening notch 43 is formed at the lower end portion of the shaft opening auxiliary wire 41, the region 19 can be easily cut and removed. After that, the upper portion of the cap seal B is cut off using the peripheral unsealing auxiliary wire 42 (see FIG. 10). By completely removing the upper portion of the cap seal B, the cap portion 62 can be completely exposed. After that, the cap portion 62 can be removed and the contents in the container 6 can be taken out.

On the other hand, it is assumed that the cap seal B is illegally opened for the purpose of mischief, for example, without purchasing the product and performing the regular opening. In this respect, when the cap seal B of the container C with a cap seal of the present invention is tampered with, the reading area 2 is broken and the mechanical reading medium 21 is divided, so the presence or absence of tampering is found at the store. it can.
Specifically, when the upper portion of the cap seal B corresponding to the cap portion 62 is grasped by hand and rotated in the opening direction together with the cap portion 62, as shown in FIG. 11, it is broken substantially along the breaking auxiliary line 3. Further, a crack is generated in the circumferential direction from the end of the breaking auxiliary line 3 (second breaking auxiliary line 32), and the reading area 2 is broken. Since the cap seal B is twisted between the upper part and the lower part at the time of this illegal opening, the cap seal B may be broken not only along the breaking auxiliary line 3 but also along a part of the circumferential unsealing auxiliary line 42. However, the reading area 2 is broken because it breaks at the breaking auxiliary line 3.

In the cap seal B of the present invention, since the breaking auxiliary line 3 is formed so that the virtual extension line of the breaking auxiliary line 3 intersects the edge of the reading area 2, the breaking auxiliary line 3 at the time of unauthorized opening. To the reading area 2, and the mechanical reading medium 21 provided in the reading area 2 is divided.
The information of the mechanical reading medium 21 thus divided is difficult to read by a reader (mechanical reading device), and the presence or absence of unauthorized opening can be found in the cash register operation in the over-the-counter sales. Particularly, as in the illustrated example, when the mechanical reading medium 21 is a bar code and the auxiliary breaking line 3 and its virtual extension line extend in the longitudinal direction of the bar portion 21a of the bar code, a plurality of bar codes are provided. The bar code is divided in the adjacent bar parts 21a of the bar code in which the bar parts 21a are arranged in multiple stages (see FIG. 11). The bar code in which the adjacent bar portions 21a are separated as described above cannot be read by the reader, and the presence or absence of the unauthorized opening can be surely found.
By using the cap seal A of the present invention, the presence or absence of illegal opening can be mechanically detected as well as visually observed by humans, so that mischief can be easily detected and, by extension, mischief can be prevented.

The present invention is not limited to the first embodiment described above, but can be modified in various ways.
Hereinafter, various other embodiments of the present invention will be described, but the same configurations and effects as those of the first embodiment will not be described (as they have been described), and terms and reference numerals will be used as they are.

[Second Embodiment]
In the first embodiment, the second breaking auxiliary line 32 is formed parallel to the circumferential direction of the tubular body 1. For example, as shown in FIG. 12, the first breaking auxiliary line 31 is a cylinder. The second breaking auxiliary line 32 may be formed parallel to the circumferential direction of the tubular body 1 and extend in the circumferential direction at an angle with respect to the circumferential direction of the tubular body 1. In this case, the virtual extension line of the second auxiliary line 32 for breaking forms an acute angle with the edge of the reading area 2.
The inclination angle of the second breaking auxiliary line 32 with respect to the circumferential direction is not particularly limited as long as the virtual extension line intersects the edge of the reading area 2 at an acute angle, but if the angle is too large, it is illegally opened. At times, the mechanical reading medium 21 may not be sufficiently divided. From this viewpoint, the inclination angle is preferably more than 0 degree and 60 degrees or less, and more preferably more than 0 degree and 45 degrees or less. In the illustrated example, the second breaking auxiliary line 32 is inclined downward toward the reading region 2, but may be inclined upward toward the reading region 2 (not shown). ). Further, from the end of the first breaking auxiliary line 31, the second breaking auxiliary line 32 is inclined downward toward the reading region 2, and the second auxiliary breaking line is inclined upward toward the reading region 2. Lines 32 and may be formed respectively (not shown).

FIG. 13 shows the cap seal A in which the first auxiliary line for breaking 31 that is inclined with respect to the circumferential direction of the tubular body 1 is formed. In this example, the second breaking auxiliary line 32 is arranged on the virtual extension line of the inclined first breaking auxiliary line 31, and the virtual extension line of the second breaking auxiliary line 32 is at the edge of the reading area 2. Crossing
In this case, the second breaking auxiliary line 32 is not limited to be tilted downward, and may be parallel to the circumferential direction or may be tilted upward.

In the first embodiment, the first breaking auxiliary line 31 is formed to be relatively long in the circumferential direction of the tubular body 1. For example, as shown in FIG. 31 may be relatively short. In this case, the first breaking auxiliary line 31 may be formed parallel to the circumferential direction of the tubular body 1, but is formed to be inclined with respect to the circumferential direction of the tubular body 1 as shown in the illustrated example. In particular, it is more preferable that the end portion of the first breaking auxiliary wire 31 is formed in the vicinity of the circumferential opening auxiliary wire 42. By forming in this way, at the time of illegal opening, breakage occurs substantially along the peripheral opening auxiliary line 42 and the breakage auxiliary line 3, and the reading area 2 is broken by a crack from the break.

In addition, in the first embodiment described above, the breaking auxiliary line 3 is formed symmetrically with respect to the center of the mechanical reading medium 21 in the width direction as a center line. However, the breaking auxiliary lines 3 may be asymmetrically formed on the left side and the right side of the mechanical reading medium 21 (not shown).
Further, as shown in FIG. 15, the breaking auxiliary line 3 may be formed only on the left side (or the right side) of the mechanical reading medium 21. As shown in FIG. 15, the cap seal A having the auxiliary breaking line 3 formed only on the left side is preferably attached to a container having a cap portion 62 whose opening direction is counterclockwise when viewed from above. .. This is because if the cap portion is rotated in the opening direction at the time of illicit opening, a crack is easily generated from the end portion of the auxiliary breaking wire 3 toward the reading area 2.
As described above, as a method of forming the breaking auxiliary wire 3 in a left-right asymmetrical manner or forming the breaking auxiliary wire 3 only on one side, (a) the breaking auxiliary wire 3 is previously formed at a predetermined position of the heat-shrinkable film. If necessary, the shaft unsealing auxiliary wire 41 and the peripheral unsealing auxiliary wire 42 are also formed simultaneously, and they are formed into a tubular shape to form the tubular body 1. (b) After the tubular body 1 is formed, Inserting a penetration prevention plate in the cylinder, and forming the breaking auxiliary wire 3 (and the shaft unsealing auxiliary wire 41 and the circumferential unsealing auxiliary wire 42 at the same time if necessary) from one side of the cylindrical body 1. There is a method.

Furthermore, in the first embodiment, the breaking auxiliary line 3 is formed so that the virtual extension line of the breaking auxiliary line 3 extends in the longitudinal direction of the bar portion 21a of the barcode, but the invention is not limited to this, and for example, As shown in FIG. 16, the auxiliary breaking line 3 may be formed such that the virtual extension line of the auxiliary breaking line 3 extends in a direction orthogonal to the longitudinal direction of the bar portion 21a of the barcode. In this case, in order to enable the adjacent bar portion 21a of the bar code to be separated at the time of illegal opening, one of the auxiliary auxiliary wires 3'for breaking (in the illustrated example, the right side in the drawing) is read with its extension virtual line having the bar code. It is preferable to arrange so as to intersect the edge of the region 2 and to arrange the other (left side in the illustrated example) of the auxiliary breaking line 3″ on the lower side (or upper side) of the barcode.

Further, in the first embodiment described above, the peripheral unsealing auxiliary wire 42 and the breaking auxiliary wire 3 are formed, but the circumferential unsealing auxiliary wire 42 may also serve as the breaking auxiliary wire 3.
FIG. 17 shows the cap seal A in which the peripheral unsealing auxiliary wire 42, which is an auxiliary wire intended to be used when the cap seal is normally opened, is also an auxiliary wire intended to break at the time of unauthorized opening. ..
In FIG. 17, the peripheral unsealing auxiliary line 42 is formed in the circumferential direction, but a region (uncut area) where the unsealing auxiliary line is not formed is secured in a part of the circumferential direction. The reading area 2 is provided by providing a mechanical reading medium 21 in that area. The end of the auxiliary line 42 for unsealing is arranged at the edge of the reading area 2 or in the vicinity of the edge, and the virtual extension line of the auxiliary line 42 for unsealing intersects the edge of the reading area 2. ..
If the container with the cap seal attached with the cap seal A is illegally opened, the container is broken substantially along the peripheral opening auxiliary line 42, and the reading area 2 on the extension line is also broken.

Further, in each of the above-described embodiments, the cut line is used as the second breaking auxiliary line 32, but a perforation line may be used as the second breaking auxiliary line 32 (not shown).
Furthermore, in each of the above-described embodiments, the shaft opening auxiliary wire 41 and the opening cut 43 are formed in the tubular body 1, but they may be omitted if necessary.
Further, the tubular body 1 may be formed with an auxiliary opening line other than the shaft opening auxiliary line and the peripheral opening auxiliary line.
