Description

  The present invention includes a container main body, a lid that is externally fitted to the container main body, and a heat-shrinkable film that is mounted across the container main body and the lid so as to prevent the lid from being removed. It is related with the provided package.

  2. Description of the Related Art Conventionally, for example, a container main body having an accommodating part as a container for accommodating food items such as ice cream, confectionery, solid soup and toys, etc., and a lid that is fitted to the container main body and closes the accommodating part of the container main body Are widely used. In such a container, since the lid is fitted and attached to the container body, the lid may be inadvertently removed during transportation. In order to prevent such a lid from coming off, a heat shrinkable film for sealing is mounted across the container body and the lid.

  However, in order to take out the contents from the package sealed with the film, two operations of removing the lid from the container body after opening the heat-shrinkable film are required.

Patent Document 1 discloses a technique that can easily open the heat-shrinkable film and remove the lid.
Specifically, Patent Document 1 discloses a packaging container including a container main body, a rubber cap that closes an opening of the container main body, and shrink wrapping that is mounted across the container main body and the rubber cap. ing. The rubber cap is formed with a finger hook portion that can hook the finger tip from above the shrink wrapping to push up the rubber cap. Such a finger-hanging part is realized, for example, by forming a concave part or a convex part having a size enough to catch the fingertip on a part of the rubber cap. In the shrink wrap, perforations are formed at portions corresponding to the openings of the container body.
In order to take out the contents from the packaging container, the rubber cap is pushed up by hooking the fingertip onto the finger hooking portion from above the shrink packaging. When the rubber cap is pushed up, the shrink wrap is broken along the perforation and the rubber cap is removed from the container body. Accordingly, the shrink wrap can be opened and the rubber cap can be removed at the same time, so that the contents can be easily taken out.

However, in the technique of Patent Document 1, the cap and the shrink wrap cannot be opened simultaneously unless the cap is pushed up strongly.
Moreover, since it is necessary to form a finger hook part in a cap, there exists a problem that the manufacturing cost of a package rises. That is, the shape of the container is various, and caps of various shapes are used according to the shape. However, in order to form a finger-hanging portion for each cap, a new mold must be manufactured. In particular, when the lid is formed from a sheet material such as paper, it is extremely difficult to form the finger-hanging portion as described above.

Japanese Utility Model Publication No. 4-33249

  Then, this invention makes it a subject to provide the package body which can perform the removal of a cover body and the opening of a heat-shrinkable film simultaneously and easily.

  The present invention comprises a top-opening container body having a side wall erected from the bottom, a lid attached to the container body, and a heat-shrinkable film mounted across the container body and the lid. When the lid is attached to the container main body, the lid has an extending portion located outside the side wall portion of the container main body, and the heat shrinkable film is first heat-shrinkably attached to the extending portion of the lid. The mounting portion, the second mounting portion that is heat-shrink mounted on the side wall portion of the container body, and the non-floating portion that is located between the first mounting portion and the second mounting portion and that floats from the side wall portion below the extending portion. The first mounting portion of the heat-shrinkable film is formed with a perforation along the circumferential direction, and the non-adhered portion has at least one upper end portion continuous with the perforation. Provided is a package in which the score line is formed in the vertical direction.

Since the heat-shrinkable film is mounted over the container body and the lid body, the packaging body according to the present invention is sealed so that the lid body does not come off from the container body.
The lid body has an extending portion located outside the side wall portion of the container body in the attached state. Therefore, a step is generated at the boundary portion between the extension portion of the lid and the side wall portion of the container body, and a finger can be put on the lower end portion of the extension portion.
On the other hand, perforations are formed along the circumferential direction in the first mounting portion of the heat-shrinkable film, and between the first mounting portion and the second mounting portion of the heat-shrinkable film from the side wall portion of the container body. There is a floating non-contact part. Further, a cut line in which the upper end portion is connected to the perforation is formed in the non-contact portion in the vertical direction. Therefore, when the finger is placed on the lower end portion of the extended portion of the lid body to which the heat-shrinkable film is attached and the lid body is pushed up and the lid body is pushed up, the upper end portion of the incision line is used as the cleavage start point. The heat-shrinkable film is divided along the perforations. Therefore, the package can simultaneously remove the lid and open the heat-shrinkable film.

  As a preferred embodiment, a configuration in which at least a pair of left and right cut lines are provided can be mentioned. Since this package has a pair of left and right cut lines connected to the perforation, when the lid is pushed up, two or more perforations are generated, so that the heat-shrinkable film is further divided. It becomes easy.

  Further, as a more preferable aspect, a configuration in which the pair of left and right cut lines are formed so as to be separated from each other as they approach the perforation. For example, a configuration in which a pair of left and right cut lines are formed in an inverted C-shaped slope is illustrated. In such a package, when the lid is pushed up, a tensile force in the vertical direction tends to act at the perforation starting point of the perforation. For this reason, it is possible to simultaneously remove the lid and open the heat-shrinkable film with a smaller force.

  The package according to the present invention can simultaneously remove the lid and open the heat-shrinkable film. Moreover, the package according to the present invention can be opened at the same time with a relatively small push-up force.

Hereinafter, the present invention will be specifically described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a container main body 2, a lid body 6 externally fitted to the container main body 2, and a tubular heat-shrinkable film 9 mounted across the container main body 2 and the lid body 6. The package provided is shown.

As shown in FIG. 2, the container body 2 is formed in a concave upper surface opening type. The container body 2 is composed of a bottom member 3 and a side wall member 4 each formed in a thin shape. The material for forming the bottom member 3 and the side wall member 4 is not particularly limited, and sheets such as paper (including paper material laminated with a synthetic resin film), synthetic paper, synthetic resin sheet, and laminated sheets thereof. Materials can be used.
In addition, the container main body 2 shown in figure is comprised by what assembled the sheet material (for example, what is called a paper cup). However, the container body 2 may be a synthetic resin molded product (a sheet molded product, an injection molded product, or the like).

The bottom member 3 includes a bottom portion 31 and a yarn bottom portion 32. The bottom portion 31 is formed in a substantially circular shape, and the yarn bottom portion 32 extends downward from the entire outer peripheral portion of the bottom portion 31 and is formed in an annular shape when viewed from the bottom.
The bottom 31 is not limited to a substantially circular shape, and may be formed in a polygonal shape such as a regular hexagon or a regular octagon.

On the other hand, the side wall member 4 includes a side wall portion 41, a yarn bottom portion 42, and a locking portion 43.
The side wall 41 is formed in a tapered cylindrical shape having a larger diameter as it goes upward. The bottom member 3 is fitted inside the side wall portion 41, and the inner peripheral surface of the side wall portion 41 and the outer peripheral surface of the yarn bottom portion 32 of the bottom member 3 are bonded. The side wall portion 41 and the bottom portion 31 of the bottom member 3 form a housing portion 5 having an opening formed on the upper surface.
In addition, the side wall part 41 is not limited to a cylindrical shape, For example, you may form in the cylinder shape of a cross-sectional polygonal shape. Further, the side wall portion 41 is not limited to a tapered shape, and may be formed in a straight body shape.
The yarn bottom portion 42 wraps around the yarn bottom portion 32 from the lower end portion of the side wall portion 41 so as to cover the yarn bottom portion 32 of the bottom member 3, and is adhered to the outer peripheral surface and inner peripheral surface of the yarn bottom portion 32. Yes.
The locking portion 43 is formed in an annular shape extending from the upper end portion of the side wall portion 41 in the radially outward direction of the side wall portion 41. In the present embodiment, the locking portion 43 is formed by curling the sheet material in the radially outward direction of the side wall portion 41 at the upper end of the side wall portion 41.
Note that the locking portion 43 is not limited to a configuration in which the locking portion 43 is integrally formed with the same member as the side wall portion 41. May be.

The lid body 6 attached to the container body 2 has a closing portion 7 that closes the opening of the housing portion 5, and extends downward from the closing portion 7, and when fitted to the container body 2, the side wall portion 41. And an extending portion 8 located on the outer side. The material of the lid 6 is not particularly limited, and is similar to the container body 2 such as paper (including paper material laminated with a synthetic resin film), synthetic paper, synthetic resin sheet, and laminated sheets thereof. A sheet material can be used.
Note that the illustrated lid body 6 is configured by assembling sheet materials (for example, a paper lid formed with a concave paper). Of course, the lid 6 may also be formed of a synthetic resin molded product (sheet molded product, injection molded product, etc.).

The blocking part 7 is formed in a substantially circular shape. The diameter of the blocking part 7 is formed larger than the outer diameter of the locking part 43. The closing portion 7 is placed on the upper end portion of the locking portion 43 and closes the opening.
The extending portion 8 has an outer ring portion 81 and an inner ring portion 82. The outer ring portion 81 is formed in an annular shape extending downward from the entire periphery of the peripheral portion of the closing portion 7. On the other hand, the inner ring portion 82 extends inward and upward from the lower end portion of the outer ring portion 81, and is formed in an annular shape along the inner peripheral surface of the outer ring portion 81. The inner diameter of the inner ring portion 82 is formed larger than the outer diameter of the side wall portion 41 of the container body 2. Therefore, the extended portion 8 of the lid body 6 fitted is located outside the side wall portion 41, and a gap portion 83 is provided between the extended portion 8 and the side wall portion 41.
The downward extension length of the extending portion 8 of the lid body 6 is shorter than the vertical length of the side wall portion 41 of the container body 2, for example, 1/50 times to 1/4 of the vertical length of the side wall portion 41. About double is preferable, and 5 to 25 mm can be given as a specific length.
As described above, the extending portion 8 is formed shorter than the side wall portion 41, and the outer diameter of the extending portion 8 is larger than the outer shape of the side wall portion 41. A step in the radial direction is generated at the boundary portion 41.
When such a step is generated, a finger or the like is hooked on the lower end portion of the extending portion 8, the lid body 6 is pushed upward, and the lid body 6 can be detached from the container body 2.

The inner ring portion 82 constituting the extended portion 8 is formed to have a vertical length that does not reach the closing portion 7 at its upper end. Preferably, the upper and lower lengths of the inner ring portion 82 and the closing portion 7 are formed so as to ensure a clearance in which the locking portion 43 of the container body 2 is fitted. In addition, the inner diameter of the inner ring portion 82 is smaller than the outer diameter of the locking portion 43.
Therefore, when the lid 6 is externally fitted to the container body 2, the locking portion 43 of the container body 2 is fitted into the gap between the upper end portion of the inner ring portion 82 of the lid body 6 and the closing portion 7, and the lid The body 6 is fitted to the container body 2. The lid body 6 fitted to the container main body 2 by such uneven fitting can be removed by raising it to the upper side of the container main body 2 as described above.

Next, a tubular heat-shrinkable film 9 is heat-shrinkably mounted on the container body 2 and the lid body 6 across the both.
The material of the heat-shrinkable film 9 is not particularly limited. For example, styrene resin such as polystyrene, polyester resin such as polyethylene terephthalate and polylactic acid, olefin resin such as polypropylene and cyclic olefin, polycarbonate, and vinyl chloride A film containing one kind selected from thermoplastic resins such as resins, or a mixture of two or more kinds can be used. The film may be a laminated film in which two or more kinds of heat-shrinkable films are laminated, or a laminated film in which a non-heat-shrinkable layer such as a metal vapor deposition layer is laminated on a heat-shrinkable film. The film can be provided with heat shrinkability by forming and stretching the film by a known production method. The stretching treatment is usually at a temperature of about 70 to 110 ° C., and is 2.0 to 8.0 times, preferably 3.0 to 7.times in the width direction (circumferential direction when formed into a cylindrical shape, hereinafter the same). It is performed by stretching about 0 times. Further, in the longitudinal direction (longitudinal direction when formed into a cylindrical shape, the same shall apply hereinafter), the stretching treatment may be performed at a low magnification of 1.5 times or less, for example. The obtained film becomes a uniaxially stretched film or a biaxially stretched film slightly stretched in a direction orthogonal to the main stretch direction.
Although the thickness of a heat-shrinkable film is not specifically limited, For example, about 20-80 micrometers, Furthermore, the thing about 20-60 micrometers can be used.

The heat shrinkage rate of the heat-shrinkable film 9 is not particularly limited as long as it is close to the container body 2 and the lid body 6 by heat shrinkage. Usually, the heat shrinkage rate in the width direction (90 ° C. warm water) 10 seconds) is about 40% or more, preferably about 50% or more. Further, the film may be slightly heat-shrinked in the longitudinal direction, and the heat shrinkage rate (immersion in 90 ° C. warm water for 10 seconds) in the longitudinal direction is about −3 to 15%.
However, heat shrinkage rate (%) = [{(original length in the width direction (or longitudinal direction)) − (length after immersion in the width direction (or longitudinal direction))} / (width direction (or longitudinal direction) ) Original length)] × 100.

As shown in FIGS. 1 and 4, the heat-shrinkable film 9 is formed in a cylindrical shape. That is, the heat-shrinkable film 9 is formed in a cylindrical shape by overlapping and bonding both side end portions of the rectangular film (note that the bonding portion (center seal portion) is in all the drawings. Not shown). When the tubular heat-shrinkable film 9 is divided for each container mounting portion, the first mounting portion 91 that is in close contact with the outer peripheral surface of the extending portion 8 of the lid 6 and the outer peripheral surface of the side wall portion 41 of the container main body 2 are arranged. It has the 2nd mounting part 92 which closely_contact | adheres, and the non-contact | adherence part 93 which is between the 1st mounting part 91 and the 2nd mounting part 92, and is not closely_contact | adhered to the side wall part 41 of the container main body 2.
Specifically, as shown in FIG. 3, the first mounting portion 91 of the heat shrinkable film 9 is also heat shrink mounted on the periphery of the upper surface portion of the closing portion 7. Therefore, the first mounting portion 91 of the mounted cylindrical heat-shrinkable film 9 is in close contact with the entire outer peripheral surface of the extending portion 8 and the peripheral portion of the closing portion 7.
The reason why the first mounting portion 91 of the film 9 is mounted over the periphery of the upper surface portion of the lid 6 is to seal the lid 6 with the tubular film 9. Therefore, as long as the lid 6 can be sealed with the tubular heat-shrinkable film 9, it is not always necessary to attach the film 9 to the periphery of the upper surface portion of the lid 6. For example, when the extended portion 8 of the lid body 6 is formed in a cylindrical shape whose diameter is reduced toward the upper side, or when the outer peripheral surface of the extended portion 8 is formed in an uneven shape, The lid 6 can be sealed so as not to be removed simply by mounting the first mounting portion 91 of the film 9 only on the extending portion 8.

  On the other hand, the second mounting portion 92 of the film 9 is heat shrink mounted on a portion of the outer peripheral surface of the side wall portion 41 of the container body 2 that is below the lower end portion of the extending portion 8. In the present embodiment, the side wall 41 of the container body 2 is formed in a cylindrical shape that is reduced in diameter as it goes downward, so that by attaching the second mounting portion 92 to the side wall 41, the cylindrical shape is reduced. The entire heat-shrinkable film 9 does not slip out in either the upper or lower direction of the container.

The tubular heat-shrinkable film 9 can be obtained by overlapping both side ends of the heat-shrinkable film raw materials of the above-described various materials into a tubular shape and cutting it into a predetermined length. The obtained cylindrical heat-shrinkable film 9 is put on the container body 2 and the lid body 6 by heat-shrinking mainly in the circumferential direction (radial direction).
Since the heat-shrinkable film 9 shrinks in the circumferential direction as described above, the first mounting portion 91 corresponding to the extending portion 8 of the lid body 6 has, as shown in FIG. The second mounting portion 92 corresponding to the side wall 41 of the container body 2 is in close contact with the side wall 41. On the other hand, the non-contact portion 93 corresponding to the step portion of the container (below the lid 6 and the boundary portion between the side wall 41 of the container body 2) is in a floating state without being in close contact with the side wall 41 of the container body 2. . This is because the heat-shrinkable film 9 that has been heat-shrinked is difficult to adhere along the right-angled portion of the step.

Next, as shown in FIGS. 1 and 4, the cylindrical heat-shrinkable film 9 is formed with at least one perforation 94 and secondary perforation 95 that are parallel to the circumferential direction.
The perforations 94 are formed in the circumferential direction except for a part of the heat-shrinkable film 9 (the central portion in FIG. 4A). Accordingly, the perforation 94 is formed in an end shape having two end portions. The perforation 94 is formed in the first mounting portion 91 corresponding to the extending portion 8 of the lid body 6. Therefore, when the heat-shrinkable film 9 is attached, the perforation 94 is arranged along the circumferential direction of the extending portion 8 in the corresponding region of the extending portion 8.
Preferably, the perforation 94 is formed so as to be disposed above the lower end portion of the extending portion 8. Further, it is preferable that the perforation 94 is formed at a position below the upper end portion of the extending portion 8.
On the other hand, the secondary perforation 95 is formed below the perforation 94. The secondary perforations 95 are formed over the entire circumferential direction of the heat-shrinkable film 9 (formed endlessly), and are formed in the second mounting portion 92 corresponding to the side wall portion 41 of the container body 2. Therefore, when the heat-shrinkable film 9 is attached, the secondary perforation 95 is arranged along the circumferential direction of the side wall portion 41 in the corresponding region of the side wall portion 41.
The secondary perforation 95 may be formed in the non-contact portion 93. However, if the heat-shrinkable film 9 is formed on the non-contact portion 93, when the heat-shrinkable film 9 is heat-shrink mounted on the container body 2, the through-holes that form the secondary perforations 95 are connected as described below, and the heat-shrinkable film 9 Therefore, the secondary perforation 95 is preferably formed in the second mounting portion 92.

Here, a perforation means what the through-hole and the non-penetrating part which penetrated to the front and back of the heat-shrinkable film 9 were formed alternately like the sewing trace of a perforation needle. The through-hole is formed in a needle hole shape (circular hole or elliptical hole) when viewed from the front, a long straight line when viewed from the front, or the like. As shown in FIG. 4 (c), the length of the through hole A (diameter in the case of a needle hole) and the length of the non-through portion B (adjacent through hole A). The distance between them is not particularly limited and can be set as appropriate.
The perforation 94 only needs to have a coupling force that can be broken when the lower end portion of the extending portion 8 of the lid 6 is pushed upward with a finger or the like, and a conventionally known perforation can be applied. Specifically, the length of the through hole A of the perforation 94 is preferably, for example, about 0.5 mm to 2.0 mm, and the length of the non-through portion B of the perforation 94 is 0.5 mm to 1.0 mm. The degree is preferred.
Further, the secondary perforation 95 only needs to have a connecting force that can be torn when the portion of the heat-shrinkable film 9 between the perforation 94 and the secondary perforation 95 is pulled with a finger or the like. For example, the length of the through hole A is preferably about 0.5 mm to 2.0 mm, and the length of the non-through portion B of the secondary perforation 95 is preferably about 0.5 mm to 1.0 mm.

In addition, the non-contact portion 93 of the heat-shrinkable film 9 is formed with a pair of left and right cut lines 96 and 96 ′ whose upper ends are connected to the perforation 94 in the vertical direction. The pair of cut lines 96 and 96 ′ are provided away from each other in the circumferential direction, and are formed so as to go away as they approach the perforation 94 (for example, a reverse C shape in front view).
Specifically, the upper end portion of the cut line 96 is one end portion of the perforation 94 (hereinafter referred to as a continuous end portion P), and the upper end portion of the cut line 96 ′ is the other end portion of the perforation 94. It is connected to the end (hereinafter referred to as a continuous end P ′). The cut lines 96, 96 ′ are formed at a predetermined angle θ with respect to the direction in which the perforation 94 is formed. As described above, the cut lines 96 and 96 ′ may be formed in the vertical direction (predetermined angle) with respect to the perforation 94. Preferably, the cut lines 96 and 96 ′ are formed with respect to the perforation 94. It is preferable that they are formed at a right angle or an obtuse angle with respect to the perforation 94. This is because the first mounting portion 91 of the heat-shrinkable film 9 can be satisfactorily divided along the perforation 94 when the lower end portion of the extending portion 8 of the lid 6 is pushed upward. Particularly preferably, the score lines 96 and 96 ′ are formed at an obtuse angle with respect to the perforation 94. The predetermined angle θ is not particularly limited, but is preferably about 120 to 160 degrees.
The pair of left and right perforations 96 and 96 ′ are preferably formed at substantially the same angle with respect to the perforation 94, but the pair of left and right perforations 96 and 96 ′ have different angles with respect to the perforation 94, respectively. It may be formed.
Note that the lower end portions of the cut lines 96 and 96 ′ are connected to the secondary perforation 95, respectively.

  The cut lines 96, 96 ′ may be a single slit (elongated through hole) such as an elongated linear shape, a broken line shape, or a curved shape penetrating the front and back surfaces of the heat-shrinkable film 9. Such short through holes and non-penetrating portions may be alternately formed. Especially, it is preferable that the cut lines 96 and 96 'are formed by a single long and narrow cut line penetrating the front and back surfaces. This is because when the tubular heat-shrinkable film 9 is heat-shrink mounted on the container body 2 and the lid body 6, the film 9 shrinks in the circumferential direction and is pulled, so as shown in FIG. This is because 96 and 96 'appear as openings 97 and 97' having a width in the circumferential direction.

Further, in the present embodiment, a sub cut line 98 is formed between the pair of left and right cut lines 96, 96 ′.
This sub-cut line 98 forms a predetermined angle with respect to the circumferential direction of the cylindrical heat-shrinkable film 9 at least partially, and is formed in a front view mountain shape, for example, as shown in FIG. can do. As with the cut line 96, the sub cut line 98 may be either a cut line or a perforation, and among these, the sub cut line 98 is preferably a cut line. This is because, similarly to the score lines 96 and 96 ', when the heat-shrinkable film 9 is thermally contracted, the secondary score line 98 appears as an opening 99 (FIG. 1).
The auxiliary cut line 98 is connected to the secondary perforation 95 at both ends. Therefore, the end portion of the auxiliary cut line 98 is connected to the lower end portion of the cut lines 96 and 96 ′ via the secondary perforation 95. Further, the sub-cut line 98 is formed in a front view mountain shape, and an intermediate portion is formed in the non-contact portion 93. Thus, when at least a part of the sub-cut line 98 is formed in the non-contact portion 93, the opening 99 appears in the non-contact portion 93, a finger is inserted into the opening 99, and the extension portion of the lid body 6. The lower end of 8 can be pushed up.
Further, there is no particular limitation between the sub-cut line 98 and the cut lines 96, 96 ′, but the length of the sub-perforation 95 between the opening 99 and the lower end portions of the openings 97, 97 ′. , 1 to 20 mm, preferably 3 to 15 mm.

The package 1 having the above configuration covers the container body 2 with the lid body 6, engages the locking portion 43 and the inner ring portion 82, and externally fits the lid body 6 to the container body 2. Next, the heat-shrinkable film 9 formed in a cylindrical shape can be obtained by covering the container body 2 and the lid body 6 and heat-shrinking.
As shown in FIG. 1, the obtained package has a first contact portion 91 of the heat-shrinkable film 9 that is in close contact with the extending portion 8 and the closing portion 7 of the lid body 6, and a second contact portion of the film 9. While 92 closely_contact | adheres to the side wall part 41 of the container main body 2, the cut lines 96 and 96 'and the sub cut line 98 expand, and opening 97, 97', 99 arises.

In such a package 1, the contents accommodated in the accommodating portion 5 are taken out from the container body 2 by removing the lid 6.
When removing the lid 6 from the container body 2, a finger is put into the opening 99 and the finger is put on the lower end portion of the extending portion 8 of the lid 6 and pushed up.
When the lid body 6 is pushed up, the first mounting portion 91 is pulled upward along with the lid body 6, while the second mounting portion 92 is fixed to the container body 2, so that the cut lines 96, 96 ′ A vertical tensile force acts on the secondary perforation 95 between the lower end portion of the secondary perforation line 98 and the secondary cut line 98, and the portion of the secondary perforation 95 is torn. Thereby, the opening 99 and the openings 97 and 97 ′ are connected, and the tensile force in the vertical direction then acts on the connecting end portions P and P ′, whereby the connecting end portions P and P ′ are used as the cleavage starting points. The first mounting portion 91 is divided along the perforation 94 in the circumferential direction. When the first mounting portion 91 tears along the perforation 94, the upper portion and the lid 6 are separated from the container body 2 with reference to the perforation 94 of the first mounting portion 91, as shown in FIG. The lid 6 can be removed from the container body 2.
Thus, the package 1 of the present invention can simultaneously remove the lid 6 and open the heat-shrinkable film 9.
In addition, after removing the lid 6 from the container main body 2, the lower side region (second mounting portion 92) of the film 9 remains attached to the side wall 41 of the container main body 2. If necessary, if the second mounting portion 92 of the heat-shrinkable film 9 is divided using the secondary perforation 95, the heat-shrinkable film 9 can be completely removed from the container.

Since the package 1 is formed with cut lines 96, 96 ′ and sub-cut lines 98 extending in the longitudinal direction on the heat-shrinkable film 9, when the film 9 is heat-shrink mounted, In this case, openings 97, 97 'and 99 are produced. Such an opening can be used as an opening for the heat-shrinkable film 9.
Furthermore, since the upper ends of the score lines 96 and 96 ′ are connected to the perforation 94 and are provided as a pair on the left and right sides, the heat-shrinkable film 9 extends along the perforation 94 from the continuous starting points P and P ′. Is cut well. For this reason, by pushing up the lid 6 with a relatively small force, the lid 6 can be opened and the heat-shrinkable film 9 can be opened (divided) simultaneously. In particular, since the score lines 96 and 96 ′ are formed with an obtuse angle with respect to the perforation 94, the vertical tensile force applied to the heat-shrinkable film 9 when the lid body 6 is pushed up is the continuous end. It is easy to act in the circumferential direction starting from the parts P and P ′. For this reason, the heat-shrinkable film 9 can be divided with a small force.
Moreover, since the packaging body 1 of the present invention does not need to be separately formed with a finger hook portion or the like on the lid as in the prior art, it can be applied to containers that have been used for general purposes. .

Next, the modification of the package 1 of this invention is shown.
In the packaging body 1 according to the above embodiment, a gap 83 is formed between the side wall 41 of the container body 2 and the extending part 8 of the lid 6. For example, as shown in FIG. The outer peripheral surface of the portion 41 may be in contact with the inner peripheral surface of the inner ring portion 82. Thus, even if the side wall 41 and the extended portion 8 are in contact with each other, a step corresponding to the thickness of the extended portion 8 of the lid body 6 occurs, and a finger is put on the lower end portion of the extended portion 8 of the lid body 6. This is because the lid 6 can be pushed up.
Further, the extending portion 8 of the lid body 6 is not limited to the configuration having the outer ring portion 81 and the inner ring portion 82, and may be configured by only the outer ring portion 81, for example. In the case where the outer ring portion 81 alone is used, it is preferable that engagement protrusions that can be engaged with the locking portions 43 are provided on the inner peripheral surface of the outer ring portion 81 at appropriate positions.

  Moreover, in the said embodiment, although the 2nd mounting part 92 of the heat-shrinkable film 9 is mounted | worn only to the side wall part 41 of the container main body 2, for example, this 2nd mounting part 92 is made into the lower end of the side wall part 41. You may mount | wear so that it may go into the bottom part 31 of the container main body 2 from a part. If the 2nd mounting part 92 is mounted to the bottom part 31, there is no possibility that the heat-shrinkable film 9 will shift | deviate upwards. Such a mode of mounting up to the bottom 31 is a preferable mode when mounting the cylindrical heat-shrinkable film 9 on the container body 2 having the straight barrel side wall 41, for example.

Next, a modification of the heat-shrinkable film 9 will be shown. However, in the following modifications, the perforation and the cut line formed in the heat-shrinkable film 9 are different from those in the above embodiment, and the other points are the same as those of the package 1 in the above embodiment.
<Modification 1>
In the heat-shrinkable film 9 shown in FIG. 7, the secondary perforation 95 is not formed, the cutting perforation 101 is between the lower end portion of the cut line 96 and one end portion of the sub cut line 98, and It is formed between the lower end portion of the cut line 96 ′ and the other end portion of the sub cut line 98.
This cutting perforation 101 may not be formed when the lower end portions of the cut lines 96 and 96 ′ and the end portions of the sub cut lines 98 are close to each other.
The packaging body 1 using the heat-shrinkable film 9 of this modification also has the same function and effect as the above embodiment.

<Modification 2>
The heat-shrinkable film 9 shown in FIG. 8 is a mode in which the sub-cut lines 98 are not formed as compared with the heat-shrinkable film 9 of FIG. In this case, the lower end portions of the cut line 96 and the cut line 96 ′ are connected via a secondary perforation 95. When the auxiliary cut line 98 is not formed as in this modification, the non-contact portion 93 (the portion indicated by S in FIG. 8) between the cut lines 96 and 96 ′ is directed from the outside to the inside. Press. Since there is a gap 83 between the extended portion 8 of the lid body 6 and the upper portion of the container body 2, when the portion S of the non-contact portion 93 is pressed from the outside to the inside, the extended portion 8 of the lid body 6. Will bend. Since the non-contact portion 93 of the film 9 is deformed following the bending of the extended portion 8, the secondary perforation 95 between the cut lines 96 and 96 'is torn. Thereby, the cut lines 96 and 96 ′ are connected, and the portion S of the non-contact portion 93 is greatly opened.
When a finger is put on the lower end portion of the extending portion 8 of the lid body 6 through the large opening portion S and the lid body 6 is pushed upward, the first mounting portion 91 is formed along the perforation 94 as in the above embodiment. Tearing, the removal of the lid 6 and the opening of the heat-shrinkable film 9 can be performed simultaneously.

<Modification 3>
The heat-shrinkable film 9 shown in FIG. 9 is an aspect in which the cut lines 96 and the cut lines 96 ′ are connected to each other at the lower ends. As shown in the figure, the secondary perforation 95 may not be formed or may be formed. The packaging body 1 using the heat-shrinkable film 9 of this modification can also open the lid 6 and the heat-shrinkable film 9 at the same time as in the above embodiment.

<Modification 4>
The heat-shrinkable film 9 shown in FIG. 10 has no sub-cut line 98 formed, and a cut line 102 for cutting is provided between the lower ends of the cut lines 96 and 96 ′. This cutting line 102 for cutting is composed of one elongated straight through hole 102a that penetrates the front and back surfaces and is parallel to the circumferential direction, and cutting perforations 102b formed on both sides thereof. ing. The package 1 using the heat-shrinkable film 9 of the present modification can also open the lid 6 and the heat-shrinkable film 9 at the same time as in the third modification.

<Modification 5>
In the heat-shrinkable film 9 shown in FIG. 11, the perforation 94 formed in the first mounting portion 91 is composed of a first perforation 94a and a second perforation 94a ′.
Specifically, the first perforation 94a and the second perforation 94a ′ are each formed to have a substantially half circumference length of the tubular heat-shrinkable film 9.
One end P of the first perforation 94a is connected to the upper end of one cut line 96, and one end P 'of the second perforation 94a' is connected to the other cut line 96 '. It is connected with the upper end part. The other end Q of the first perforation 94a and the other end Q ′ of the second perforation 94a ′ are substantially opposite to the part where the cut line 98 is formed (centering on the container body 2). At a position rotated approximately 180 °). The heat-shrinkable film 9 is formed with a first vertical perforation 94 b that is connected to the other end Q of the first perforation 94 a and extends in the vertical direction to the lower end edge of the heat-shrinkable film 9. Similarly, a second vertical perforation 94b ′ connected to the other end Q ′ of the second perforation 94a7 and extending in the vertical direction to the lower end edge of the heat-shrinkable film 9 is formed.

  The packaging body 1 to which the heat-shrinkable film 9 of such a modification is attached corresponds to the extending portion 8 by putting a finger on the lower end portion of the extending portion 8 of the lid body 6 and pushing up the lid body 6. The first perforation 94a and the second perforation 94a ′ (that is, the perforation 94 formed in the first mounting portion 91) are divided. In this modification, the perforation 94 is composed of two substantially perforated perforations 94a and 94a ′. Therefore, when the lid 6 is pushed up, the other of the first perforation 94a and the second perforation 94a ′. It is divided to the end portions Q and Q ′. Thereafter, as shown in FIG. 12, when the lid 6 is drawn downward, the heat-shrinkable film 9 is divided in the vertical direction along the first vertical perforation 94b and the second vertical perforation 94b '. Thereby, the 2nd mounting part 92 of the heat-shrinkable film 9 is parted, and the whole heat-shrinkable film 9 can be easily removed from a container.
