Description

  The present invention relates to a container with a cap seal and a cap seal in which the cap seal is heat-shrink mounted on various containers such as beverage containers.

Conventionally, a cap seal has been used in order to protect the cap portion of a container in which beverages, seasonings, and the like are placed, and to ensure that the cap portion is not opened (Patent Document 1). The cap seal is attached at least to the neck including the cap portion of the container.
Patent Document 1 discloses a cap seal in which a perforation line for guaranteeing sealing is formed in a portion covering a narrow mouth portion of a bottle. With respect to a package in which such a cap seal is attached to a bottle including a narrow mouth portion, when only the cap seal is pulled out of the bottle for mischief purposes, it is planned to be cut off at the perforation line for guaranteeing sealing, and a tear will occur. . In the present specification, a “fissure” refers to a breakage mark that is generated by cutting at a perforation line or the like.
However, the perforation line for guaranteeing sealing may not be sufficiently cut off at the perforation line, and there may be a case where no tear is generated so that the presence or absence of opening can be visually confirmed. In particular, when the difference in diameter between the narrow mouth portion and the enlarged diameter portion is relatively small, it is difficult to cut at the perforation line for guaranteeing sealing, and the above-described tear is not easily generated. If the cap seal does not break at the perforation line, it is difficult to find out whether the cap seal has been pulled out visually by pushing the pulled cap seal back to its original position, and measures to detect mischief and prevent mischief are required. .

<Outline of container with cap seal>
1 to 3, a container A with a cap seal of the present invention includes a container B having a cap portion 1 and a neck portion 2, and a cap seal C <b> 2 that is heat shrink fitted to the neck portion 2 including the cap portion 1. ing.
In the following, regarding the cap seal, the reference sign C is attached to the cap seal before heat shrinking, the reference sign C1 is attached to the preformed cap seal, and the reference sign C2 is attached to the cap seal attached to the container by heat shrinkage.
First, the details of the container B and the cap seal C will be described, and then the details of the container A with a cap seal will be described.

<Container>
As shown in FIG. 4, the container B includes a trunk portion 3 having a storage space for storing contents, and a neck portion 2 including the cap portion 1 that is a neck portion 2 connected to the trunk portion 3.
The outer shape of the body portion 3 is not particularly limited as long as it is hollow so that the contents can be accommodated therein. In addition to a substantially quadrangular prism shape (substantially rectangular parallelepiped shape) as shown in the illustrated example, although not illustrated, the outer shape is substantially cylindrical or substantially elliptical It may be a substantially polygonal column shape such as a columnar shape or a substantially triangular prism shape, a substantially polygonal pyramid shape such as a substantially triangular pyramid shape, a substantially saddle shape, or a substantially daruma shape. Here, in the present specification, the “substantially” shape means a shape allowed in the technical field to which the present invention belongs. For example, “substantially” in a substantially polygonal column shape or a substantially polygonal pyramid shape includes a shape in which a corner is chamfered, a shape in which a part of a side is slightly inflated or depressed, and a shape in which a side is slightly curved. It is. In addition, “substantially” of a substantially cylindrical shape, a substantially elliptical column shape, a substantially saddle shape, and a substantially daruma shape includes a shape in which a part of an arc is inflated or depressed, a shape in which a part of the arc is a straight line or a diagonal line It is.

  The trunk | drum 3 contains the bottom face part 31, and the container B can be self-supported in the bottom face part 31. FIG. The contents stored in the trunk 3 are not particularly limited, and examples thereof include alcoholic beverages, water, milk, coffee and other beverages, soy sauce, soup and other liquid seasonings or granular seasonings, shampoos, body soaps, and the like. Sanitary goods.

The neck portion 2 has a hollow cylindrical shape, and constitutes a storage space for storing contents in cooperation with a storage space inside the trunk portion 3. The neck 2 is integrally formed simultaneously with the body 3. However, the neck 2 and the body 3 may be formed separately and integrated by joining them together. In the illustrated example, the neck portion 2 projects from the upper end portion of the body portion 3 in parallel with the axial direction of the body portion 3. But the neck part 2 is not limited to when provided in the upper end part of the trunk | drum 3, For example, you may be provided in the side part of the trunk | drum 3 (not shown). Further, the neck portion 2 is not limited to a case where the neck portion 2 is provided so as to protrude parallel (substantially upward) to the axial direction of the body portion 3, and may be provided, for example, on the side of the body portion 3 (not shown). . When the neck 2 is protruded on the side of the body 3, the axial direction of the neck 2 may be non-parallel to the axial direction of the body 3.
A spout is opened at the upper end of the neck 2. The spout is in communication with the storage space of the trunk portion 3 and the neck portion 2. In order to open and close the spout, a cap portion 1 is detachably attached to the neck portion 2. The cap part 1 in the illustrated example is screwed to the outside of the neck part 2 by a screw action. However, the cap 1 is attached to the neck 2 so as to be able to close the spout, for example, it is fitted on the inside of the spout, and is fitted on the outside of the spout. A form, a form which can open and close a spout via a hinge, etc. may be sufficient (all forms are not illustrated).
The cap part 1 attached by the screw action as shown in the illustrated example has a substantially cylindrical shape whose upper surface is closed. The neck portion 2 to which the cap portion 1 is attached has a male screw 29 formed at least on the attachment portion 21 to which the cap portion 1 is attached.

  The material of the trunk | drum 3, the neck part 2, and the cap part 1 is not specifically limited, Glass, a synthetic resin, a metal, pottery etc. are mentioned each independently. For example, the trunk portion 3 and the neck portion 2 are simultaneously and integrally formed of the same material (a kind selected from glass, synthetic resin, metal, and earthenware), and the cap portion 1 is formed of synthetic resin or metal.

The outer shape of the neck portion 2 including the cap portion 1 is not a straight body shape but a non-straight body shape having a diameter difference in the extending direction of the neck portion 2 (in the illustrated example, the axial direction of the body portion 3). The straight body shape is a shape in which the circumferential length of the outer surface of the neck portion 2 does not change in the extending direction of the neck portion 2. The neck portion 2 including the cap portion 1 means the neck portion 2 in a state where the cap portion 1 is attached. The outer shape of the neck portion 2 including the cap portion 1 is as follows: (1) When the outer shape of the cap portion 1 is the same as or larger than the outer shape of the neck portion 2, the outer shape of the cap portion 1 and the outer shape of the neck portion 2 other than the cap portion (2) When the outer shape of the cap portion 1 is smaller than the outer shape of the neck portion 2, the outer shape of the neck portion 2 is formed. Examples of the case (2) where the outer shape of the cap portion 1 is smaller than the outer shape of the neck portion 2 include a case where the cap portion is in a form fitted inside the spout.
The outer surface of the neck portion 2 including the cap portion 1 has a protruding surface 2a partially protruding radially outward, and a recessed surface 2b having a smaller circumferential length than the protruding surface 2a. The protruding surface 2a and the recessed surface 2b are adjacent to each other in the axial direction of the neck portion 2, and the protruding surface 2a is disposed on the cap portion 1 side. In the illustrated example, the protruding surface 2a is located on the upper side, and the recessed surface 2b is located directly below the protruding surface 2a.

Specifically, the neck portion 2 includes an attachment portion 21 to which the cap portion 1 is attached, a large-diameter portion 22 that is continuously formed below the attachment portion 21 and protrudes outward, and below the large-diameter portion 22. A diameter-reduced portion 23 that is continuously formed and smaller than the circumference of the large-diameter portion 22, and is formed between the diameter-reduced portion 23 and the body portion 3, and the circumference length gradually increases toward the body portion 3. And an enlarged portion 24 having a portion. Both the large diameter portion 22 and the enlarged portion 24 have a larger perimeter than the reduced diameter portion 23. Accordingly, with respect to the reduced diameter portion 23, portions larger than the circumferential length of the reduced diameter portion 23 are formed on both sides in the axial direction of the neck portion 2 (upper side and lower side in the illustrated example). The enlarged portion 24 is a portion that connects the reduced diameter portion 23 and the body portion 3, and has a gradually increasing circumference as it goes downward. However, the large-diameter portion 22 may not be formed in the neck portion 2.
In the illustrated example, except for the male screw 29, the attachment portion 21 has a straight body shape. The peripheral length of the attachment portion 21 is substantially the same as the peripheral length of the reduced diameter portion 23, and therefore the peripheral length of the large diameter portion 22 is greater than either the peripheral length of the attachment portion 21 or the peripheral length of the reduced diameter portion 23. large. In the illustrated example, the outer shape of the cap portion 1 is larger than the outer shape of the attachment portion 21 of the neck portion 2, and therefore, the outer shape corresponding to the attachment portion 21 in the neck portion 2 including the cap portion 1 corresponds to the outer shape of the cap portion 1. To do. In the illustrated example, the circumference of the cap portion 1 is substantially the same as the circumference of the large diameter portion 22.

The large-diameter portion 22 is a portion that partially protrudes outward in the midway portion in the axial direction of the neck portion 2. In the example of illustration, the large diameter part 22 protrudes in the whole circumferential direction of the neck part 2, for example. The large diameter portion 22 is formed integrally with the neck portion 2 and constitutes a part of the neck portion 2. Such a large diameter portion 22 is also called a bead portion.
The width 22W of the large diameter portion 22 is not particularly limited, and is, for example, 1 mm to 15 mm, and preferably 2 mm to 10 mm. The width 22W of the large-diameter portion 22 refers to the length of the large-diameter portion 22 in the axial direction of the neck portion 2.
The protrusion height H of the large diameter portion 22 is not particularly limited and is, for example, 0.5 mm to 8 mm, and preferably 1 mm to 5 mm. If the cap seal C of the present invention is attached, even if the protruding height H of the large diameter portion 22 is relatively small, such as about 0.5 mm to 2 mm, a tear may occur when the cap seal C2 is pulled out. become. The protruding height H of the large-diameter portion 22 refers to the difference between the outer surface of the large-diameter portion 22 and the outer surface of the reduced-diameter portion 23 in a side view.
The outer shape of the large-diameter portion 22 is formed in a substantially cylindrical shape, but is not limited to this, and may be formed in a substantially elliptical column shape as in the case of the body portion 3.

The reduced diameter portion 23 is disposed below the large diameter portion 22. Preferably, the reduced diameter portion 23 is provided directly below the lower end portion 22 c of the large diameter portion 22. The outer surface of the reduced diameter portion 23 is recessed inward than the outer surface of the large diameter portion 22 in a side view. Preferably, the reduced diameter portion 23 is recessed inward from the outer surface of the large diameter portion 22 in the entire circumferential direction.
The reduced diameter portion 23 in the illustrated example is formed in a straight cylinder shape immediately below the lower end portion 22 c of the large diameter portion 22, and the circumferential length gradually increases from the straight cylinder portion toward the lower portion, leading to the enlarged portion 24. ing. However, on the condition that the outer surface of the reduced diameter portion 23 has a portion that is recessed inward from the outer surface of the large diameter portion 22 in a side view, the reduced diameter portion 23 gradually goes around, for example, as it goes downward. It may be formed so that the length becomes smaller, or may be formed so that the circumferential length becomes smaller further downward after the circumferential length becomes larger.
The width 23W of the reduced diameter portion 23 is not particularly limited and can be set as appropriate. However, if it is too small, it is difficult to position the cut line in the region corresponding to the recessed surface 2b when the cap seal C is attached. There is a risk. From this point of view, the width 23W of the reduced diameter portion 23 is preferably 5 mm or more, and more preferably 10 mm or more. The width 23W of the reduced diameter portion 23 refers to the length of the reduced diameter portion 23 in the axial direction.

Moreover, although the external shape of the reduced diameter part 23 of the example of illustration is formed in substantially cylindrical shape, it is not limited to this, Like the trunk | drum 3, it may be formed in substantially elliptical column shape. Preferably, the outer shape of the reduced diameter portion 23 is similar to the outer shape of the large diameter portion 22.
A step due to the difference in circumference is generated between the reduced diameter portion 23 and the large diameter portion 22.
The circumferential length difference between the reduced diameter portion 23 and the large diameter portion 22 is not particularly limited. For example, the circumferential length of the reduced diameter portion 23 is the circumference of the large diameter portion 22 × 0.7 times to the large diameter portion 22. The circumference is 0.99 times, preferably, the circumference of the large diameter portion 22 is 0.8 times the circumference of the large diameter portion 22 is 0.98 times. According to the cap seal C of the present invention, even when the circumferential difference (relatively small step) is relatively small as described above, a tear occurs when the cap seal C2 is pulled out.

The outer surface of the large-diameter portion 22 corresponds to a protruding surface 2a that partially protrudes outward, and the outer surface of the reduced-diameter portion 23 corresponds to a recessed surface 2b that has a smaller circumferential length than the protruding surface 2a.
In the present invention, the cap seal C is heat shrink mounted on the outer surface of the neck 2 including the cap 1. Of the outer surface of the neck portion 2 including the cap portion 1, the surface on which the cap seal C is mounted is referred to as a mounted surface. The mounted surface includes a protruding surface 2a and a recessed surface 2b. The heat-shrink mounted cap seal C2 is in close contact with the mounted surface including the protruding surface 2a and the recessed surface 2b.

[Cap seal]
The cap seal C has a cylindrical body 4 in which a heat-shrinkable film is formed in a cylindrical shape. The cap seal C before being thermally contracted to the container B can be opened in a cylindrical shape as shown in FIGS. In the present invention, it should be noted that “cap seal C” means a state before being attached to the container B.
The cap seal C is opened in a cylindrical shape when mounted on the container B, but is folded into a flat shape as shown in FIGS. 7 to 9 during normal transportation and storage. In a realistic manufacturing process, the cap seal C is a continuous body in which a plurality of cap seals C are continuously connected, and is provided in the form of a continuous body that is folded into a flat shape. The cap seal is obtained.

The heat-shrinkable film is a film that shrinks in the heat shrink direction when heated to a heat shrink temperature. Examples of the heat shrink temperature include 60 ° C to 120 ° C.
Examples of the heat-shrinkable film include heat-shrinkable synthetic resin films, nonwoven fabrics, foamed resin films, and laminated films thereof. The laminated film may be a laminate of a layer having no heat shrinkability and a layer having heat shrinkability, provided that the whole laminate has heat shrinkability. Preferably, a synthetic resin film is used as the heat-shrinkable film.
The material of the synthetic resin film is not particularly limited. Polyester resins such as polyethylene terephthalate and polylactic acid; Olefin resins such as polypropylene and cyclic olefin; Styrene resins such as polystyrene and styrene-butadiene copolymer; Polyamide Resin; 1 type chosen from thermoplastic resins, such as vinyl chloride system resin, or 2 or more types of mixtures, etc. are mentioned. The heat-shrinkable synthetic resin film may be composed of a single resin layer, or may be composed of a plurality of different or different types of resin layers.

As the heat-shrinkable film, a film that mainly heat-shrinks in at least the first direction may be used, and a film that slightly heat-shrinks or heat-extends 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. Such a stretched film is oriented at least in the first direction, and has a property of tearing easily in the first direction (tearability).
The heat shrinkage rate in the first direction (heat shrink 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. In addition, although the heat shrinkage rate in the said 1st direction is so preferable that it is large, since there exists a limit naturally, the heat shrinkage rate in the said 1st direction is theoretically less than 100%. When the heat-shrinkable film is a film that changes heat 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 thermal contraction rate means thermal elongation.
However, the heat shrinkage ratio is the length of the film before heating (original length) and the length of the film after immersion of the test piece in warm water at 85 ° C. for 10 seconds (length after immersion). It is a ratio and is obtained by substituting into the following formula.
Thermal contraction 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 heat-shrinkable film may be provided with a design print layer as necessary (the design print layer is not shown). The heat-shrinkable film may be either transparent or non-transparent, but it is designed on the back side (the back side of the heat-shrinkable film is the surface that becomes the inside of the cylinder when it is made into the cylindrical body 4). When providing a printing layer, the thing excellent in transparency is used. In the present specification, transparent (colorless transparent or colored transparent) refers to a case where 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 measurement method based on JIS K 7361 (a test method for the total light transmittance of a plastic-transparent material).
Although the thickness of the heat-shrinkable film is not particularly limited, for example, a film having a thickness of about 20 μm to 100 μm, further about 20 μm to 80 μm can be used.

The film is rolled into a cylindrical shape so that the first direction (heat shrink direction) of the heat-shrinkable film is the circumferential direction, and the first side end 41 is overlapped with the second side end 42 and bonded. By forming the seal portion 43, the cylindrical body 4 is configured. The seal portion 43 extends in a strip shape in the axial direction of the cylindrical body 4.
The bonding method of the first side end portion 41 and the second side end portion 42 is not particularly limited, and examples thereof include welding using a solvent and bonding using an adhesive.
The circumferential length of the cylindrical body 4 is, for example, the maximum circumferential length of the mounted surface of the container B × 1 to 1.5 ×, preferably more than 1 × and less than or equal to 1.3 ×. More preferably, it is the same × 1.02 times to the same × 1.15 times. As will be described later, when the cap seal C is attached to a part of the cap part 1, the large diameter part 22, the reduced diameter part 23, and the enlarged part 24 of the container B, the circumferential length of the tubular body 4 is determined by Of the parts 1, 22, 23, and 24, it is set on the basis of the part with the longest circumference.

The cylindrical body 4 is formed with a plurality of perforation lines and cut lines.
Here, in the present specification, the perforation line is a line in which through-hole portions penetrating in the thickness direction of the heat-shrinkable film (tubular body 4) are intermittently connected like a stitch mark of a sewing needle. That is, the perforation line is a line formed by alternately connecting the through-hole portions and the non-through portions. The length of the perforated through-hole portion refers to the length in the direction in which the perforated line extends, and the length of the non-penetrated portion of the perforated line is the length of the two through-hole portions existing on both sides of the target non-penetrated portion. The shortest straight line length.
Moreover, in this specification, a score line is a cut of the predetermined length penetrated in the thickness direction of a heat-shrinkable film (tubular body 4). The length of the cut line refers to the straight line length between both ends of the target cut line.

Specifically, the cylindrical body 4 has a vertical perforation line 51 extending in the axial direction, horizontal perforation lines 61, 62, and 63 extending in the circumferential direction, and a length of 5 mm or more extending while being inclined with respect to the circumferential direction. A cut line 7 is formed. Further, a plurality of horizontal perforation lines 61, 62, 63 extending in the circumferential direction are formed, and the plurality are arranged in a multistage shape in the axial direction. About the cap seal C before heat shrinkage, the length of the cut line 7 is set to 5 mm or more because the length of the cut line 7 is easily changed to 4 mm or more when the cap seal C is heat shrunk. is there.
As described above, the circumferential direction of the cap seal C is the direction around the axis of the cap seal C. However, when the cap seal C is folded flat, the circumferential direction is perpendicular to the axial direction.

The vertical perforation lines 51 and 51 are extended in the axial direction of the cylindrical body 4 as a pair of left and right. Although the vertical perforation line 51 may be inclined and extended with respect to the axial direction, the vertical perforation line 51 is preferably extended in parallel with the axial direction as in the illustrated example. The vertical perforation line 51 is formed between the upper edge and the lower edge of the cylindrical body 4. For example, the vertical perforation line 51 may be formed from the upper edge to the lower edge of the tubular body 4, or the upper portion of the tubular body 4 (this upper portion is the upper edge of the tubular body 4. It may be formed from the upper part of the cylindrical body 4 to the lower part (this lower part is the lower part of the cylindrical body 4). It may be formed up to a portion that does not include the edge and is separated upward from the lower edge). In the illustrated example, the vertical perforation lines 51, 51 are formed from the upper part of the cylindrical body 4 to the lower edge.
The length of the through hole portion of the vertical perforation line 51 can be set as appropriate, and is, for example, 0.5 mm to 2 mm. The length of the non-penetrating portion of the vertical perforation line 51 can be set as appropriate, and is, for example, 0.5 mm to 2.5 mm.

In the illustrated example, three horizontal perforation lines 61, 62, and 63 are formed at predetermined intervals in the axial direction. Hereinafter, when distinguishing the upper and lower three horizontal perforations, the first, second and third are added to the beginning.
The first horizontal perforation line 61 is formed at a position spaced downward from the upper edge of the cylindrical body 4. The first horizontal perforation line 61 may be inclined and extended with respect to the circumferential direction, but preferably, the first horizontal perforation line 61 is in the circumferential direction of the tubular body 4 as in the illustrated example. It extends in parallel. Moreover, the 1st horizontal perforation line 61 may be formed in the whole circumferential direction. However, the first horizontal perforation line 61 is a belt-like region sandwiched between the pair of vertical perforation lines 51 in order to remove the belt-like region 45 sandwiched between the pair of vertical perforation lines 51, 51 without being broken. Except for 45, it is formed in the circumferential direction. Note that two belt-like regions 45 sandwiched between the pair of vertical perforation lines 51 can be considered in the circumferential direction of the cylindrical body 4, but here indicate the narrow belt-like regions 45. Further, the first horizontal perforation line 61 may be formed in the entire circumferential direction in a range excluding the belt-like region 45 or may be formed in a part of the circumferential direction.
In the illustrated example, the first horizontal perforation line 61 extends from the upper end portion of one vertical perforation line 51 to one side in the circumferential direction except for the belt-like region 45 and the region 46 opposite to the belt-like region 45. The other vertical perforation line 51 extends from the end to the opposite side in the circumferential direction.
The length of the through-hole part of the 1st horizontal perforation line 61 can be set suitably, for example, is 0.5 mm-2 mm. The length of the non-penetrating portion of the first horizontal perforation line 61 can be set as appropriate, and is, for example, 0.5 mm to 2.5 mm.

The second horizontal perforation line 62 is formed at a position separated downward from the first horizontal perforation line 61. The second horizontal perforation line 62 may be inclined and extended with respect to the circumferential direction. Preferably, however, the second horizontal perforation line 62 is connected to the circumferential direction of the tubular body 4 as in the illustrated example. It extends in parallel. Moreover, the 2nd horizontal perforation line 62 may be formed in the whole circumferential direction. However, as will be described later, since the opening cut line 8 is formed on the circumferential extension line of the second horizontal perforation line 62, the second horizontal perforation line 62 is a belt-like region sandwiched between the pair of vertical perforation lines 51. Except for 45, it is formed in the circumferential direction.
In the illustrated example, the second horizontal perforation line 62 extends in the circumferential direction from the middle part in the axial direction of one vertical perforation line 51 to the middle part in the axial direction of the other vertical perforation line 51 except for the belt-like region 45. It is installed.
The length of the through-hole part of the 2nd horizontal perforation line 62 can be set suitably, for example, is 0.5 mm-2 mm. The length of the non-penetrating portion of the second horizontal perforation line 62 can be set as appropriate, and is, for example, 0.5 mm to 2.5 mm.

  An opening cut 8 is formed in the narrow belt-like region 45 as necessary. The opening cut 8 is formed, for example, on the circumferential extension line of the second horizontal perforation line 62. The opening cut 8 is a cut having a predetermined length penetrating in the thickness direction of the tubular body 4, similarly to the cut line 7. The length of the opening cut line 8 can be set as appropriate, and is, for example, about 5 mm to 10 mm.

The cut line 7 has an end shape and is formed at a position away from the second horizontal perforation line 62. The cut line 7 is preferably formed in a region corresponding to at least the diameter-reduced portion 23 (the recessed surface 2b) of the container B when the cap seal C is heat-shrink mounted on the container B.
The cut line 7 is inclined and extended with respect to the circumferential direction. The cut line 7 may be formed at one place, or may be formed independently at a plurality of places. In the illustrated example, cut lines 7 and 7 are formed in the left and right sides of the narrow belt-like region 45 as a reference. One cut line 7 is formed on the seal part 43 so as to divide the seal part 43 in the circumferential direction.
The inclination angle α (see FIG. 7) with respect to the circumferential direction of the cut line 7 is not particularly limited as long as it is an acute angle, and is, for example, 1 to 35 degrees, preferably 1.5 to 25 degrees, and more preferably. Is between 2 degrees and 20 degrees. If the inclination angle α is too small, there is a possibility that a good tear will not occur when the cap seal C2 is pulled out. On the other hand, if the inclination angle α is too large, the cylindrical body 4 is greatly contracted in the circumferential direction when the cap seal C is attached to the neck portion 2 by heat shrinkage, but it is difficult to contract in the axial direction. The portion of the line 7 is greatly expanded, and a hole may be formed in the surface of the cap seal C2 after mounting, so that the mounting appearance of the cap seal C2 is deteriorated.

The length of the cut line 7 is 5 mm or more, preferably 8 mm or more, more preferably 10 mm or more. By setting the length of the cut line 7 of the cap seal C before heat shrinkage to 5 mm or more, when the cap seal C2 is pulled out, the tearing force is propagated from the cut line 7 to the perforation line, and a good tear is generated. Become. Further, the upper limit of the length of the cut line 7 is not particularly limited, but if it is too large, the appearance of the cap seal C2 may be deteriorated. From this viewpoint, the length of the cut line 7 is, for example, 15 mm or less.
The incision line 7 may be extended in a straight line inclined with respect to the circumferential direction, or an arc shape or a bent shape inclined with respect to the circumferential direction (the bent shape has a dogleg shape or a zigzag shape). Included).
When the cap seal C is attached to the neck portion 2 by heat shrinkage, the cut line 7 is not easily expanded, so that the cut line 7 is preferably formed in a straight line as shown in the illustrated example.

The third horizontal perforation line 63 is connected to at least one end 7 a of at least one of the cut lines 7, 7 formed in the left and right regions with respect to the belt-like region 45. ing. Preferably, the third horizontal perforation line 63 is connected to at least one end portion 7a of each of the two cut lines 7, 7, as shown in the figure. It should be noted that the perforation line is connected to the end portion of the cut line means that the end portion of the cut line and the through hole portion of the perforation line are connected via one uncut portion. Say. In other words, that the perforation line is connected to the end portion of the cut line means that the perforation line is formed with an uncut portion between the through hole portion and the end portion of the cut line. Say. The uncut portion is synonymous with the non-penetrating portion of the perforation line, but is referred to as an uncut portion in order to distinguish it from the non-penetrating portion of the perforation line. In the present embodiment, the end portion of the third horizontal perforation line 63 is connected to the end portion of the cut line 7.
The third horizontal perforation line 63 may be connected to only one end portion 7a of the cut line 7, or may be connected to one end portion 7a of the cut line 7 and the opposite end portion 7b. It may be provided continuously. The one end portion 7 a of the cut line 7 is preferably the lower end portion of the both end portions of the cut line 7. The lower end of the illustrated example is the end opposite to the protruding surface 2a when the cap seal C is attached to the neck 2 of the container.

In the illustrated example, the third horizontal perforation line 63 includes a third upper horizontal perforation line 631 connected to an end 7 b (upper end) opposite to the cut line 7, and an end on one side of the cut line 7. And a third lower horizontal perforation line 632 provided continuously with the portion 7a (lower end).
The length of the uncut portion between the through hole portion of the third upper horizontal perforation line 631 and the end portion 7b on the opposite side of the cut line 7 can be set as appropriate, but if it is too large, the cap seal C2 is pulled out. Sometimes, the tearing force may not easily propagate from the cut line 7 to the third upper horizontal perforation line 631. From this point of view, the length of the uncut portion between the through hole portion of the third upper horizontal perforation line 631 and the end portion 7b on the opposite side of the cut line 7 is preferably more than zero and 2 mm or less. 3 mm to 1.5 mm is more preferable. The length of the uncut portion refers to the shortest straight line length between the through hole portion of the third upper horizontal perforation line 631 and the end portion 7 b on the opposite side of the cut line 7.
The length of the uncut portion between the through hole portion of the third lower horizontal perforation line 632 and the end portion 7a on one side of the cut line 7 can be set as appropriate. For the same reason as the third upper horizontal perforation line 631, the length of the uncut portion between the through hole portion of the third lower horizontal perforation line 632 and one end portion 7a of the cut line 7 is zero. It is preferably greater than 2 mm and more preferably 0.3 mm to 1.5 mm. The length of the uncut portion refers to the shortest straight line length between the through hole portion of the third lower horizontal perforation line 632 and the end portion 7 a on one side of the cut line 7.

  The third upper horizontal perforation line 631 may be extended while being inclined with respect to the circumferential direction of the cylindrical body 4, or may be extended in parallel with the circumferential direction of the cylindrical body 4. When the third upper horizontal perforation line 631 extends while being inclined with respect to the circumferential direction, the third upper horizontal perforation line 631 may be parallel to the cut line 7 or may be extended non-parallel. The third upper horizontal perforation line 631 may be extended on an extension line of the cut line 7 or may be extended in a region other than the extension line of the cut line 7. When the third upper horizontal perforation line 631 extends on the extension line of the cut line 7, at least a part of the perforation line 631 only needs to extend on the extension line. The whole may be extended on the extension line of the cut line 7. Since the tearing force easily propagates from the cut line 7 to the third upper horizontal perforation line 631 when the cap seal C2 is pulled out, the third upper horizontal perforation line 631 is inclined and extended with respect to the circumferential direction. More preferably, it extends on the extension line of the cut line 7 (more preferably, at least a part of the perforation line 631 extends at the same inclination angle as the cut line 7). More preferably, the line 7 extends linearly on the extension line (the whole perforation line 631 extends at the same inclination angle as the cut line 7).

  The third lower horizontal perforation line 632 may be inclined and extended with respect to the circumferential direction of the cylindrical body 4, or may be extended in parallel with the circumferential direction of the cylindrical body 4. When the third lower horizontal perforation line 632 extends while being inclined with respect to the circumferential direction, the third lower horizontal perforation line 632 may be parallel to the cut line 7 or may be extended non-parallel. Further, the third lower horizontal perforation line 632 may be extended on the extension line of the cut line 7 or may be extended in a region other than the extension line of the cut line 7. When the third lower horizontal perforation line 632 extends on the extension line of the cut line 7, at least a part of the perforation line 632 may extend on the extension line, for example, the perforation line 632. The whole may be extended on the extension line of the cut line 7. For the same reason as the third upper horizontal perforation line 631, it is preferable that the third lower horizontal perforation line 632 is inclined and extended with respect to the circumferential direction, and further extends on the extension line of the cut line 7. It is more preferable that at least a part of the perforation line 632 extends at the same inclination angle as that of the cut line 7, and in particular, it extends linearly on the extension line of the cut line 7 (sewing machine More preferably, the entire line of sight 632 extends at the same inclination angle as the cut line 7).

The third upper horizontal perforation line 631 is formed up to the vertical perforation line 51. However, the end portion of the third upper perforation line may be separated from the vertical perforation line 51.
The third upper horizontal perforation line 631 connected to the opposite end portions 7b of the two cut lines 7 may be separated as shown in the illustrated example, and may be connected although not specifically illustrated.
The third lower horizontal perforation lines 632 connected to the end portions 7a on one side of the two cut lines 7 may be connected as shown in the illustrated example, or may be separated although not particularly illustrated.
The length of the through-hole part of the 3rd horizontal perforation line 63 can be suitably set on condition that it is smaller than the length of the cut line 7, for example, is 0.5 mm-2 mm. The length of the non-penetrating portion of the third horizontal perforation line 63 can be set as appropriate, and is, for example, 0.5 mm to 2.5 mm.

  The first horizontal perforation line 61, the second horizontal perforation line 62, the third horizontal perforation line 63, the vertical perforation line 51, and the cut line 7 are heated by covering the neck 2 of the container B with the cap seal C, as will be described later. It is formed in the cylindrical body 4 so that the container A with a cap seal in which the perforation line and the cut line 7 are arranged at predetermined positions with respect to the neck portion 2 can be obtained when the shrinkage is attached. Accordingly, the size of the cylindrical body 4 and the specific arrangement of the first horizontal perforation line 61, the second horizontal perforation line 62, the third horizontal perforation line 63, the vertical perforation line 51, and the cut line 7 with respect to the cylindrical body 4 are as follows. The neck portion 2 of the container B is appropriately designed according to the shape, size, dimensions, and the like.

  The cap seal C is formed, for example, by manufacturing the tubular body 4 using a heat-shrinkable film, then folding the tubular body 4 into a flat shape, and starting from the surface on one side of the flat tubular body 4. It can be obtained by engraving the line of sight 51, 61, 62, 63 and the cut line 7. As shown in FIGS. 7 and 8, the cap seal C formed by such a manufacturing method is such that the vertical perforation line 51, the horizontal perforation lines 61, 62, 63, and the cut line 7 are centered on the belt-shaped region 45. As shown in FIG.

The cap seal C can be placed on the neck 2 including the cap portion 1 while remaining in a cylindrical shape, and can be attached to the neck 2 by heat shrinkage. Alternatively, the cap seal C can be preliminarily molded and then covered on the neck 2 including the cap portion 1. It can also be attached to the neck 2 by heat shrinkage. Pre-formation means that the cap seal C is deformed into a predetermined three-dimensional shape with an inner diameter that can be put on the neck portion 2 including the cap portion 1.
10 to 12 show a preformed cap seal C1.
Pre-forming is usually performed by opening the cap seal C before heat shrinking into a cylindrical shape and fitting it into a mold, heating it to heat shrink, and changing the cap seal into a shape that conforms to the outer shape of the mold. Done.
In the cap seal C1 after the preforming, the upper portion 47 of the cylindrical body 4 is bent inward, and the lower portion 48 following the bent upper portion 47 is slightly reduced in diameter. Since the cap seal C1 preformed in this way can maintain its three-dimensional shape, a plurality of them can be stacked and stored and transported.
Moreover, you may equip the lower surface of the said bending upper part 47 with the top plate 9 as needed. The top plate 9 is formed of, for example, a relatively thick synthetic resin sheet, cardboard, metal plate, and the like, and is bonded to the lower surface of the bent upper portion 47.
Note that the specific configuration of the preformed cap seal or the preformed cap seal with the top plate is not limited to the configuration described in the present specification. For example, a conventionally known cap seal disclosed in JP-A-2006-282246 is known. A configuration can also be adopted.

<Container with cap seal>
For example, as shown in FIG. 13, the container A with a cap seal is formed by covering the neck 2 including the cap portion 1 of the container B with a preformed cap seal C1 and heating the cap seal C1 to a heat shrink temperature. can get. That is, when the cap seal C1 covering the neck portion 2 including the cap portion 1 is heated to, for example, 60 ° C. to 120 ° C., the cylindrical body 4 is thermally contracted in the circumferential direction, and is in close contact with the mounting surface of the container B. Thru | or the container A with a cap seal as shown in FIG. 3 is obtained. Note that a similar cap-sealed container can be obtained even if the neck portion 2 is covered with a cap seal C that is not preformed instead of the preformed cap seal C1 and heated and heat-shrink mounted.
In the illustrated example, the cap seal C2 is attached in close contact with a part of the cap portion 1, the large diameter portion 22, the reduced diameter portion 23, and the enlarged portion 24 following this (in this case, the surface to be attached is the cap portion). 1, a part of the reduced diameter portion 23 and the enlarged portion 24). In particular, the tubular body 4 has a region corresponding to the recessed surface 2b that is greatly heat-shrinked as compared with a region corresponding to the protruding surface 2a, so that the cap seal C2 has a region extending from the protruding surface 2a of the neck 2 to the recessed surface 2b. A step is generated at a position corresponding to the lower end 22c of the protruding surface 2a. Note that, due to the shrinkage characteristics of the cap seal C, the stepped portion of the cap seal C2 after heat shrinkage is raised from the neck portion 2 including the cap portion 1 as shown in FIG. 3, but the cap seal C2 is other than the stepped portion. Are closely attached to the neck portion 2 including the cap portion 1. The step portion of the cap seal C2 does not include a region where the cut line 7 is provided. Therefore, the region where the cut line 7 is provided is in close contact with the neck portion 2.
In the cap seal C2, the circumference of the region attached to the recessed surface 2b is smaller than the circumference of the protruding surface 2a.
Further, the cap seal C2 is bent in the axial direction of the neck portion 2 by the step portion of the cap seal C2 and the bent upper portion 47 of the cap seal C2 which is bent on the upper surface of the cap portion 1 and is locked to the upper surface. It is fixed so that it does not move easily. In particular, since the enlarged portion 24 and the trunk portion 3 exist below the cap portion 1, the cap seal C2 does not move downward.

1 to 3, the container A with a cap seal is an end-shaped cut having a length of 4 mm or more extending in an inclined manner with respect to the circumferential direction in a region corresponding to the recessed surface 2 b of the neck 2 of the cap seal C 2. A line 7 and a third lower horizontal perforation line 632 connected to at least one end 7a of the cut line 7 are provided. As described above, the cut line 7 extends at an acute angle with respect to the circumferential direction. The length of the cut line 7 of the cap seal C before heat shrinkage was 5 mm or more, but the length of the cut line provided inclined with respect to the circumferential direction becomes smaller during heat shrinkage as will be described later. Therefore, the length of the cut line 7 of the cap seal C2 after heat shrinkage is 4 mm or more.
The incision line 7 should just be arrange | positioned in the area | region corresponding to the recessed surface 2b (reduced diameter part 23) of the neck part 2. FIG. Preferably, the upper end portion 7b of the incision line 7 (the end portion on the second horizontal perforation line 62 side) is included in a range of a lower end portion 22c of the projecting surface 2a and a position 20 mm downward from the lower end portion 22c. It is preferable to arrange the cut line 7 so that the cut line 7 is included within a range of a lower end portion 22c of the projecting surface 2a and a position 15 mm below the lower end portion 22c. In particular, it is more preferable to dispose the cut line 7 so as to be included in a range of a lower end portion 22c of the projecting surface 2a and a position 10 mm below the lower end portion 22c. It is preferable that at least a region of the cap seal C2 where the cut line 7 is provided is in close contact with the reduced diameter portion 23 of the neck 2 of the container B.
The third upper horizontal perforation line 631 is provided from the lower end 22c of the projecting surface 2a of the neck 2 to the end 7b on the opposite side of the cut line 7 from the vicinity of the lower end. For example, the vicinity of the lower end portion is preferably within a range of more than zero and 3 mm or less from the lower end portion 22c of the projecting surface 2a. Further, a third lower horizontal perforation line 632 extends in the circumferential direction from one end portion 7 a of the cut line 7. The third upper horizontal perforation line 631 and the third lower horizontal perforation line 632 are each extended on an extension line of the cut line 7.
The second horizontal perforation line 62 is provided in a region corresponding to the outer surface (projecting surface 2 a) of the large-diameter portion 22 of the neck portion 2, and the first horizontal perforation line 61 corresponds to the outer surface of the cap portion 1. It is provided in the area.

Note that, after the cap seal C is attached to the container B, the size of the cap seal C is relatively large in the circumferential direction, while the size change in the axial direction is relatively small or substantially unchanged in the axial direction. This relies on the heat shrinkage rate of the heat shrinkable film constituting the cylindrical body 4.
Since the cap seal C is relatively greatly reduced in diameter in the circumferential direction after being attached to the container B, the inclination angle of the cut line 7 is larger than the inclination angle of the cut line 7 in the cap seal C before heat shrinkage. Is also slightly larger. For example, when the regions corresponding to the projecting surface 2a and the recessed surface 2b of the cap seal C are thermally contracted at a heat shrinkage rate of 5% to 30%, for example, the cut line 7 of the cap seal C2 after the heat shrinking is mounted. The inclination angle is about 0.05 to 10 degrees larger than the inclination angle of the cap seal C before mounting. In specific numerical values, the inclination angle of the cut line 7 of the cap seal C2 after the heat shrinkage is mounted is, for example, 1 degree to 50 degrees, preferably 1.5 degrees to 40 degrees, and more preferably 2 degrees. It is -30 degrees, More preferably, it is 2 degrees-20 degrees. The rate of heat shrinkage at the time of mounting is [{periphery length of cap seal C (cylindrical body 4) before heat shrinking−periphery length of the mounting surface of the container} / cap seal C before heat shrinking (cylindrical body 4)] ] × 100.

For the same reason, the length of the cut line 7, the length of the through hole portion of the first horizontal perforation line 61, the length of the non-through portion, the length of the through hole portion of the second horizontal perforation line 62, and the non-through portion The length of the through hole portion of the third horizontal perforation line and the length of the non-penetrating portion, and the length of the uncut portion (referred to as the length of the line or portion in this step), It changes according to the heat shrinkage rate when the cap seal C is attached. The amount of change in the length of the line or part of the cap seal C before heat shrinkage (how much the length of the line or part becomes smaller after heat shrinkage) varies depending on the heat shrinkage rate of the cap seal. In general, the lower limit of the amount of change in the length of the line or part of the cap seal C2 after heat shrinkage is 0.5 times, and the upper limit is less than 1 time. is there. For example, as described in the section of [Cap seal], the specific numerical value of the length of the through-hole portion of the third horizontal perforation line 63 is 0.5 mm to 2 mm. The lower limit value of the length of the through hole portion of the third horizontal perforation line 63 is 0.5 mm × 0.5 times or more and less than 0.5 mm × 1 time, and the upper limit value of the length is 2 mm × 0.5 times. This is less than 2 mm × 1 times. The length of the line or part other than the third horizontal perforation line 63 of the cap seal C2 after heat shrinkage mounting can also be calculated from the specific numerical values described in the “Cap seal” column. Preferably, the amount of change in the length of the line or part of the cap seal C2 after the heat shrinkage is 0.6 times to 0.95 times. For example, when heat shrinkage is performed at a heat shrinkage rate of 5% to 30%, the length of the line or part of the cap seal C2 after heat shrinkage attachment is independent of the line or part of the cap seal C before attachment. The length is 0.7 times or more and 0.95 times or less. Note that the amount of change in the axial direction before and after thermal contraction is almost negligible.
Since the cap seal C2 after the heat shrinkage is a three-dimensional shape including a curved surface, the inclination angle of the cap seal C2 after the heat shrinkage and the length of the line or part are determined after the cap seal C2 is removed from the container. The measurement can be performed after cutting the periphery of the measurement site from the cap seal C2 to make it flat.
The length of the line or portion described in the [Cap seal] column is set so that the length of the line or portion of the cap seal C after heat shrinkage mounting is in a preferable range in consideration of such a change amount. Is set.
In the present invention, a cut line 7 having a length of 4 mm or more is provided in the cap seal C2 in order to generate a good tear. The length of the cut line 7 of the cap seal C2 is not particularly limited as long as it is 4 mm or more, but is preferably 5 mm or more, more preferably 6 mm or more. In addition, the upper limit of the length of the cut line 7 of the cap seal C2 is not particularly limited, but if it is too large, the appearance is deteriorated, so that it is preferably 13 mm or less, and more preferably 12 mm or less. By forming the cut line 7 having a length of 5 mm or more in the cap seal C before heat shrinkage, the container with the cap seal of the present invention having the cut line 7 having a length of 4 mm or more when mounted on many kinds of containers. Can be produced. However, since it is also possible to produce a container with a cap seal having a cutting line 7 having a length of 4 mm or more, even if the cap seal C before heat shrinkage having a cutting line having a length of less than 5 mm is used, The production of a container with a cap seal is not limited to the case of using a cap seal C having a cut line having a length of 5 mm or more.

<Use of containers with cap seals>
When opening the container A with a cap seal, the upper part of the band-like region 45 of the cylindrical body 4 is cut out from the opening cut line 8 using the vertical perforation line 51. Since the first horizontal perforation line 61 is connected to the upper end portion of the vertical perforation line 51, the first perforation line 51 is cut from the first perforation line 61 to the first horizontal perforation line 61, as shown in FIG. The upper part of the cap seal C2 can be removed from the cap part 1. Further, by cutting and removing the portion covering the cap portion 1 using the second horizontal perforation line 62, the cap portion 1 can be completely exposed as shown in FIG. After that, the cap part 1 can be opened and the contents in the container B can be taken out.
The reduced diameter portion 23 and the enlarged portion 24 of the neck portion 2 are still attached with the lower portion of the cap seal C2 as shown in FIG. Since the line of sight 51 is formed, when the container B is finally discarded, the lower part of the cap seal C2 can be cut out using the vertical perforation line 51 and removed from the neck 2 of the container B.

  For example, when the cap seal C2 is to be pulled out from the neck 2 of the container B while holding the region corresponding to the cap portion 1 by hand without performing such regular opening, a large tear is formed in the surface of the cap seal C2. Comes to occur. The cap seal C2 can be pulled out by, for example, (a) simply pulling the cap seal in the axial direction, (b) pulling the cap seal in the axial direction while rotating the cap seal in the circumferential direction, and (c) the cap seal from the outside of the cap seal. The cap part is gripped, and the cap seal is pulled out together with the cap part while rotating the cap part in the direction of opening.

Specifically, when the cap seal C2 is pulled upward for mischief or the like, a step portion of the cap seal C2 that is a region between the projecting surface 2a and the recessed surface 2b of the neck 2 is extended in the axial direction and the projecting surface 2a. The diameter is expanded to the outside by hitting the lower end 22c. As a result of the expansion and diameter expansion, a tearing force is generated below the stepped portion of the cap seal C2, and as shown in FIG. 15 (a), the cut line 7 opens in a spindle shape (the symbol X is indicated in the opening portion). Attached). When the cap seal C2 is further lifted upward, the tearing force propagates from the end portions 7a, 7b of the cut line 7 to the third upper horizontal perforation line 631 and the third lower horizontal perforation line 632, as shown in FIG. As shown, a tear Y substantially along the cut line 7 and the third horizontal perforation line 63 occurs. Such a tear Y occurs when the region where the cut line 7 is provided is moved to the protruding surface 2a. The tear Y is relatively large because the break of the third horizontal perforation line 63 is connected to the cut line 7. In particular, since at least the third perforation line 63 is connected to the end portion 7a opposite to the protruding surface 2a among both end portions of the cut line 7, the tear Y is easily generated. This is because the tearing force from the end portion of the cut line 7 that occurs at the time of pulling out is larger on the side opposite to the protruding surface 2a.
According to the present invention, when the cap seal C2 attached to the container B is pulled out, a tear Y is surely generated in the surface of the cylindrical body 4. Therefore, even if the cap seal C2 is returned to the original position of the neck portion 2. The presence or absence of opening of the cap seal can be determined by visually checking the tear Y.
As described above, the cap-sealed container A of the present invention, which can easily determine opening by pulling out, can easily find an unauthorized opening action and can prevent mischief.

The present invention is not limited to the first embodiment and can be variously modified.
Hereinafter, various other embodiments of the present invention will be described, but the description of the same configurations and effects as those of the first embodiment will be omitted (assuming that the description has been made), and the terms and symbols will be used as they are.

[Second Embodiment]
In the first embodiment, the cap seal is provided with a perforation line (third horizontal perforation line) connected to the cut line, but a half cut line is used instead of or in combination with the perforation line. May be.
The half-cut line is a line that does not penetrate in the thickness direction of the heat-shrinkable film (cylindrical body 4) and is continuous with a notch cut into a substantially V shape.
Since the second embodiment is the same as the first embodiment except that the third horizontal perforation line is changed to a half cut line, the description of the configuration such as the cap seal is omitted. In the following third and subsequent embodiments, a half cut line may be used instead of or in combination with the third horizontal perforation line.
Even in the second embodiment in which a half-cut line is used instead of or in combination with the third horizontal perforation line, when the cap seal is pulled upward for a mischievous purpose or the like, the cut line becomes a spindle shape In addition, a tear is formed in which the cut line and the half-cut line are connected.

[Third Embodiment]
In the said 1st and 2nd embodiment, although the protrusion surface 2a of the neck part 2 including the cap part 1 is comprised from the outer surface of the large diameter part 22 formed in the neck part 2, it is not limited to this, For example, FIG. 16, the neck portion 2 including the cap portion 1 is a neck portion 2 in which the large-diameter portion 22 is not formed, and the cap portion 1 having a larger circumferential length than the neck portion 2, and has a tamper-evidence annular portion below. The cap part 1 which comprises 19 may be comprised.
The circumferential length of the tamper evidence annular portion 19 is larger than the circumferential length of the reduced diameter portion 23 of the neck portion 2. In the illustrated example, the circumferential length of the cap portion 1 and the circumferential length of the tamper evidence annular portion 19 are the same, but the circumferential length of the tamper evidence annular portion 19 may be larger or smaller than the circumferential length of the cap portion 1. Also good.
