If necessary, the container outer body of the present invention may have other components such as a bottom member in addition to the heat-shrinkable tubular film and the outer member.
Hereinafter, each embodiment of the present invention will be described. First, each member constituting the container outer body will be described, and then the container outer body and the container with the outer body will be described.

[First Embodiment]
FIG. 1 is a perspective view of a heat-shrinkable tubular film 1, an outer member 2, and a bottom member 3 constituting a container exterior body, and FIG. 2 is a longitudinal cross-sectional view of them.

<Heat-shrinkable tubular film>
The heat-shrinkable tubular film 1 in FIGS. 1 and 2 shows the one before heating. The heat-shrinkable tubular film 1 before heating can be opened in a substantially cylindrical shape. In addition, at the time of manufacture and storage of the heat-shrinkable tubular film 1, the heat-shrinkable tubular film 1 is usually folded into a flat shape (not shown).
The heat-shrinkable tubular film 1 has open ends on the upper and lower sides, respectively, and the heat-shrinkable tubular film 1 before heating is generally a straight cylinder having a circumferential length that does not change in the vertical direction.

The heat-shrinkable tubular film 1 is used for fixing the outer member 2 and the bottom member 3 to predetermined positions of the container.
The heat-shrinkable tubular film 1 is obtained by forming a heat-shrinkable base material into a tubular shape. The substrate is mainly composed of a heat-shrinkable film. The base material may be provided with any known print layer such as a design print layer, a protective layer, a light shielding layer, a barrier layer, and a sliding layer on the heat-shrinkable film, if necessary. The various printed layers may be independently provided on the inner surface side of the heat-shrinkable film, or may be provided on the outer surface side of the heat-shrinkable film. These print layers are not shown.
The heat-shrinkable film is a flexible film having a property (heat-shrinkable) that shrinks in at least one direction when heated to a heat-shrink temperature. Examples of the heat shrink temperature include 60 ° C to 120 ° C. The heat-shrinkable film may be either transparent (transparent means colorless and transparent or colored and transparent) or opaque. A transparent heat-shrinkable film is preferably used, and a colorless and transparent heat-shrinkable film is more preferably used. By using a transparent heat-shrinkable film, the state inside the heat-shrinkable tubular film 1 can be visually recognized from the outside.

  Examples of the heat-shrinkable film include polyester resins such as polyethylene terephthalate and polylactic acid; polyolefin resins such as polypropylene and cyclic olefin resins; polystyrene resins such as polystyrene and styrene-butadiene copolymers; A synthetic resin film made of one kind or a mixture of two or more kinds selected from thermoplastic resins such as resins can be used. The heat-shrinkable film may be composed of a single layer film (single layer film), or may be composed of a laminate in which two or more layers are laminated. When the heat-shrinkable film is a laminate, each layer of the laminate can be arbitrarily selected. The laminate is a laminate in which two or more transparent or opaque synthetic resin films having heat shrinkability are laminated; a transparent or opaque gas barrier layer on a transparent or opaque synthetic resin film having heat shrinkability A laminate in which a transparent or opaque light-shielding layer is laminated on a transparent or opaque synthetic resin film having heat shrinkability; a heat on a transparent or opaque synthetic resin film having heat shrinkability; Examples include a laminate in which a buffer layer having shrinkage or almost no heat shrinkage is laminated; a laminate in which these layers are arbitrarily laminated; and the like. Examples of the buffer layer include non-woven fabric, Japanese paper, and a soft foam resin sheet. By using the heat-shrinkable film including the buffer layer, it is possible to reduce the impact of the heat-shrinkable tubular film 1 on the container. In addition, since the buffer layer is usually opaque, the heat-shrinkable film including such a buffer layer is often opaque.

When the heat-shrinkable film is a laminate, the material of each layer may be substantially the same or different. When the heat-shrinkable film is a single layer film, a film containing a polyester resin (preferably, a polyethylene terephthalate resin) is preferable. When the heat shrinkable film is a laminate, at least one layer is preferably a polyester resin (preferably Preferably contains a polyethylene terephthalate resin), more preferably a heat-shrinkable synthetic resin film in which at least one layer contains a polyester resin.
Further, the heat-shrinkable film may further have a self-stretching property on condition that it has at least one directional heat-shrinkable property.
Although the thickness of a heat-shrinkable film is not specifically limited, For example, they are 10 micrometers-120 micrometers, Preferably they are 10 micrometers-60 micrometers. In addition, when a heat-shrinkable film contains a buffer layer, the thickness is not specifically limited, For example, it is 50 micrometers-300 micrometers.

As the heat-shrinkable film, from the viewpoint of thermal properties, a film that mainly heat-shrinks in at least one direction is used, and a film that changes heat in a direction orthogonal to one direction (hereinafter referred to as another direction) may be used. . When the base material is cylindrical (that is, when the heat-shrinkable tubular film 1 is formed using the base material), one direction of the heat-shrinkable film is the circumferential direction of the heat-shrinkable tubular film 1. Become. As such a heat-shrinkable film, for example, a uniaxially stretched or biaxially stretched film mainly stretched in one direction can be used.
The heat shrinkage rate in one direction (heat shrink direction) of the heat-shrinkable film is not particularly limited, but is preferably 30% or more, more preferably 40% or more, and further preferably 50% or more. The heat shrinkage rate in one direction is preferably as large as possible, but since there is a limit to it, the heat shrinkage rate in the one direction is theoretically less than 100%, but is usually 85% or less. . When the heat-shrinkable film is a film that undergoes heat change (heat shrinkage or heat extension) in the other direction, the heat shrinkage rate in the other direction is, for example, −3% to 5%, preferably 0% to 3%. It is. The minus of the thermal contraction rate means thermal extension.
However, the heat shrinkage ratio is the following formula: the length of the film before heating (original length) and the length of the film after immersion in warm water at 100 ° C. for 10 seconds (length after immersion). It is obtained by substituting for.
Heat shrinkage rate (%) = [{(original length in one direction or other direction) − (length after immersion in one direction or other direction)} / (original length in one direction or other direction) ] × 100.

Although the shrinkage stress of the base material including the heat-shrinkable film is not particularly limited, when the heat-shrinkable tubular film 1 is attached to the container, the outer member 2 is sufficiently deformed and bent toward the container. It is preferable that it is relatively large. For example, the shrinkage stress of the substrate is 2 MPa or more, preferably 4 MPa or more, more preferably 8 MPa or more, and further preferably 10 MPa or more. There is no particular upper limit value for the shrinkage stress, but it is 30 MPa or less as a practical value.
The shrinkage stress of the substrate including the heat-shrinkable film is cut to 80 mm in one direction and 15 mm in the other direction, and both ends of the substrate piece in one direction are held on the chuck of the stress measuring instrument ( The distance between chucks is 50 mm), which is the maximum value of shrinkage stress in one direction that occurs when this is immersed in warm water of 100 ° C. for 10 seconds.

One direction of the base material is set to the circumferential direction, the base material is rounded into a cylindrical shape, and one side end portion and the other side end portion are joined with a joining means (welding using a solvent or the like, using an adhesive). The heat-shrinkable tubular film 1 is obtained by bonding by bonding, connecting tape, ultrasonic bonding, or the like. In addition, in FIG. 1, the code | symbol 11 is represented to the said junction part.
The circumference of the heat-shrinkable tubular film 1 before heating is, for example, greater than the maximum circumference of the outer member 2 x 1 and less than or equal to 1.5 times, preferably the same x 1.01 to the same x. 1.3 times.
The heat-shrinkable tubular film 1 may be added with a known structure such as a perforation line for breaking (not shown) as necessary.

<Outer member>
The external material 2 is a member that is mounted so as to cover a part or the whole of the trunk of the container. The outer member 2 only needs to be able to cover at least a part of the body of the container, and may be mounted so as to cover the shoulder and / or the bottom of the container.
The external member 2 includes a main portion 21 that is mainly attached to the body portion of the container, and a sub-portion 22 that is provided at the lower end portion of the main portion 21 and is attached to the bottom portion of the container.
The main portion 21 is formed in a cylindrical shape, and the sub-portion 22 is formed in a plate shape. A part of the main portion 21 can be deformed so as to be contracted inward by the contraction force of the heat-shrinkable tubular film 1.

  Specifically, the main portion 21 is formed in a cylindrical shape whose upper end is an open end. The cylindrical main portion 21 may have a straight body shape, or a cylindrical shape having a reduced diameter portion whose inner peripheral length gradually decreases from the upper side to the lower side, or the inner periphery thereof from the lower side to the upper side. A cylindrical shape having a reduced diameter portion whose length is gradually reduced may be used. Examples of the cylindrical shape having a reduced diameter portion whose inner peripheral length gradually decreases from the upper side to the lower side include a substantially inverted frustum cylinder shape such as a substantially inverted frustum cylinder shape and a substantially inverted quadrangular frustum cylinder shape. Examples of the cylindrical shape having a reduced diameter portion whose inner peripheral length gradually decreases from the lower side to the upper side include a substantially frustum cylinder shape such as a substantially truncated cone cylinder shape and a substantially quadrangular frustum cylinder shape. . In the example of illustration, the main part 21 is formed in the cylinder shape of a straight body. In the present specification, the “straight cylinder” refers to a shape whose circumferential length does not change in the vertical direction.

  The interior of the main portion 21 has a storage space that communicates with the opening end. The storage space is defined by the inner peripheral surface portion of the main portion 21 (outer member 2). The shape and size of the storage space (in other words, the shape and size of the inner peripheral surface portion of the main portion 21) are not particularly limited as long as the storage space can be inserted into the body portion of the container. The size of the inner peripheral surface portion of the main portion 21 may be larger than the outer peripheral length of the barrel portion of the container, or may be approximately the same size as the outer peripheral length of the barrel portion of the container. Preferably, the shape of the main portion 21 is formed in substantially the same shape as the body portion of the container. In the present specification, the “substantially” shape means a shape allowed in the technical field to which the present invention belongs (a shape in a range that is generally recognized by those skilled in the art).

  For example, when the body portion of the container is a substantially cylindrical shape of a straight body, the shape of the main portion 21 is a substantially cylindrical shape having an inner peripheral surface portion slightly larger than the body portion or a substantially inverted truncated cone shape. Preferably, the outer member 2 is formed in a substantially rectangular tube shape or a substantially rectangular shape having an inner peripheral surface portion slightly larger than the body portion. It is preferable to form in the shape of an inverted quadrangular pyramid. In the illustrated example, the main portion 21 applied to a container having a substantially cylindrical body portion is shown. For example, the main portion 21 formed in a substantially cylindrical shape having substantially the same inner peripheral length as the outer peripheral length of the container body portion. Part 21 is shown.

  The inner surface (surface of the inner peripheral surface portion) of the main portion 21 is smooth in the illustrated example, but if necessary, a long protrusion extending in the cylinder axis direction on the inner surface of the main portion 21 (Patent Document) 1, various protrusions such as a long protrusion extending in the circumferential direction, and a plurality of dotted protrusions may be provided inwardly (see FIG. Not shown).

A cut portion 4 extending downward from the upper end of the main portion 21 is formed at the upper end portion of the main portion 21 (outer member 2). The cut portion 4 may be provided at one place, but preferably, a plurality of the cut portions 4 are formed at intervals in the circumferential direction of the main portion 21 (outer member 2). Of the main portion 21, the region where the cut portion 4 is formed (the region from the upper end 21 a of the main portion 21 to the lower end 4 b of the cut portion 4) is shrunk inward by the shrinkage force of the heat-shrinkable tubular film 1. This is a deformable region. Hereinafter, the deformable region of the outer member 2 may be referred to as a variable region.
The cut portion 4 only needs to extend downward from the upper end 21 a of the main portion 21. For example, the cut portion 4 may be formed to extend downward from the upper end 21a of the main portion 21 substantially parallel to the vertical direction, or while being inclined with respect to the vertical direction from the upper end 21a. It may be formed extending downward.

Moreover, the notch part 4 may extend linearly like the example of illustration, or may be extended and formed non-linearly, such as arc shape or zigzag shape. In the illustrated example, the cut portion 4 is formed in an elongated V-shaped linear shape in which the width of the cut portion 4 gradually decreases toward the lower end 4 b of the cut portion 4.
The plurality of cut portions 4 may be formed at equal intervals in the circumferential direction, or may be formed at unequal intervals. Since the variable region shrinks substantially uniformly, the plurality of cut portions 4 are preferably formed at equal intervals in the circumferential direction as in the illustrated example.

By forming a plurality of (two or more) cut portions 4, the upper end portion of the main portion 21 is partitioned into a plurality of small partition portions 211 in the circumferential direction. In other words, the upper end portion of the main portion 21 is composed of a plurality of small partition portions 211 arranged side by side in the circumferential direction via the cut portions 4.
The front view shape of the small partition portion 211 is appropriately set according to the shape of the cut portion 4. When the cut portion 4 is formed so as to have a small width toward the lower end as in the illustrated example, the small partition portion 211 has a substantially trapezoidal shape in front view with a gradually decreasing width toward the top. When such a small partition part 211 is contracted inward, adjacent small partition parts are less likely to interfere with each other, and each small partition part 211 is preferably inclined well along the outer surface of the container as it goes upward.

The length of the cut portion 4 in the vertical direction is not particularly limited and can be set as appropriate. For example, the vertical length of the cut portion 4 is the vertical length of the main portion 21 × 1/10 to the vertical length of the main portion 21 × 4/5. The length in the vertical direction × 1/8 to the length of the main portion 21 in the vertical direction × 2/3. The length in the vertical direction of the cut portion 4 is a linear length parallel to the vertical direction from the upper end 21a of the main portion 21 to the lower end 4b of the cut portion 4, and the length in the vertical direction of the main portion 21 is A linear length parallel to the vertical direction from the upper end 21a of the main part 21 to the lower end of the main part 21 is said.
Further, in relation to the container, it is preferable that the vertical length of the cut portion 4 is set to a length corresponding to a change region of the outer peripheral length of the container when the container is inserted into the outer member 2. 8 and 9, the shoulder portion 93 of the container corresponds to the outer peripheral length change region of the container, and the vertical length of the cut portion 4 corresponds to the shoulder portion 93 of the container when the container is inserted into the outer member 2. To the position corresponding to the lower end of the shoulder portion 93 (in other words, the upper end of the trunk portion 92).

The number of the plurality of cut portions 4 formed is not particularly limited and can be set as appropriate. As the number of the cut portions 4 is increased, the number of the small partition portions 211 is increased and the width of each of the small partition portions 211 is reduced, so that each of the small partition portions 211 is moved to the inner side by the contraction force of the heat-shrinkable tubular film 1. It becomes easy to bend. On the other hand, if the number of the cut portions 4 is too large, a large number of small partition portions 211 having a small width are generated, so that the handleability of the outer member 2 is deteriorated.
Accordingly, the number and width of the cut portions 4 are formed such that when the small partition portion 211 has appropriate bending and strength and the small partition portion 211 contracts inward, the entire inner peripheral length of the small partition portion 211 is small. It is preferable that the length is set to be approximately the same as the outer peripheral length of a portion of the container (for example, a trunk portion or a neck portion) corresponding to the partition portion 211. Since it has moderate bending and intensity | strength, the width | variety of the small division part 211 is 5 mm-20 mm, for example. The width of the small partition portion 211 refers to the length of the small partition portion 211 corresponding to the circumferential direction of the main portion 21. When the width of the small partition portion 211 is not uniform in the vertical direction, the width means its maximum value. For example, as shown in the drawing, the width of the small section 211 having a substantially trapezoidal shape when viewed from the front corresponds to the length between the lower ends 4b and 4b of the pair of adjacent cuts 4 and 4.

The length of the main portion 21 (outer member 2) in the vertical direction is not particularly limited and can be set as appropriate. Preferably, when the container is inserted into the outer member 2, it is preferable to set the length in the vertical direction of the main portion 21 so that the variable region corresponds to the shoulder portion of the container. In the vertical direction of the main portion 21 so that the region other than the variable region covers the body portion of the container and the lower end of the variable region (the lower end 4b of the cut portion 4) is substantially located at the boundary between the body portion and the shoulder portion of the container. More preferably, the length is set.
However, if the length of the outer member 2 in the vertical direction is too large, when the outer member 2 is attached to the container, the outer member 2 far exceeds the body and shoulders of the container. It is not preferable. From this viewpoint, the length of the outer member 2 in the vertical direction is preferably the vertical length of the container body × 1.02 to the vertical length of the container body × 1.2, The length in the vertical direction × 1.05 and the length in the vertical direction of the body portion of the container × 1.1 are more preferable.

The main portion 21 is flexible enough to bend by the shrinkage force of the heat-shrinkable tubular film 1 and is more rigid than the heat-shrinkable tubular film 1 and easily breaks even when an impact is applied. It is made of a material that does not. The material for forming the external material 2 is not particularly limited, and examples thereof include synthetic resins and metals, but synthetic resins are preferable.
Examples of the synthetic resin include polyolefin resins such as polyethylene and polypropylene; polyester resins; polystyrene resins; vinyl chloride resins; polycarbonate resins; polyamide resins; Moreover, when forming the outer member 2 with a synthetic resin, a non-foamed synthetic resin is used, but a foamed hard synthetic resin may be used.
The main portion 21 using a synthetic resin is typically formed by a molding method such as injection molding.
The thickness of the main portion 21 is not particularly limited. However, if the thickness is too small, the function of protecting the body portion of the container is lowered, and if it is too large, it is not preferable in terms of cost effectiveness. From this viewpoint, the thickness of the main portion 21 is preferably 0.3 mm to 3 mm, and more preferably 0.5 mm to 1.5 mm.
The thickness of the main portion 21 means the thickness when the thickness of the main portion 21 is uniform, and the maximum thickness when the thickness of the main portion 21 is uneven.

The sub part 22 has a plate shape and is formed integrally with the lower end of the main part 21. Therefore, conceptually, the lower open end of the main part 21 formed in a cylindrical shape is closed by the sub part 22.
A concave portion 222 into which a protruding end of an outer wall portion of the outer member 2 described later is fitted is formed on the outer peripheral edge portion of the sub portion 22.
The sub part 22 is formed of the same material as the main part 21 by integral molding.
The thickness of the sub part 22 is not specifically limited, For example, it is 0.3 mm-3 mm, Preferably it is 0.5 mm-2 mm.

<Bottom member>
The bottom member 3 is a member that is mounted so as to cover a part or the whole of the bottom of the container. Preferably, the bottom member 3 covers at least a peripheral portion of the bottom portion of the bottom portion of the container. The bottom member 3 is a member independent of the outer member 2. In addition, when the outer member 2 has the sub part 22 which covers the bottom part of a container like this embodiment, the outer member 2 is at least the peripheral part of the bottom part of a container from the outer side of the sub part 22 of the outer member 2 It is mounted so as to cover.
The bottom member 3 of this embodiment has the board part 31 which coat | covers the whole bottom part of a container, for example. The bottom member 3 having the plate portion 31 is mounted so as to cover the entire bottom portion including the peripheral portion.
In the illustrated example, the bottom member 3 includes the plate portion 31, an outer wall portion 32 protruding upward from the periphery of the plate portion 31, and a mounting wall portion protruding from the plate portion 31 on the inner side of the outer wall portion 32. 33.
The said plate part 31 is formed in the flat form which does not have a hole part in the surface. The top view shape of the bottom member 3 (plate portion 31) is preferably substantially the same shape and size as the bottom of the container, but may be a similar shape slightly smaller than the bottom of the container. In the illustrated example, the bottom member 3 applied to a container having a substantially circular bottom is shown. As the bottom member 3 (plate portion 31), for example, a member formed in a substantially circular shape in a top view is shown. Yes.

The outer wall portion 32 rises upward from the peripheral edge of the plate portion 31. A plurality of outer wall portions 32 may be provided protruding at a predetermined interval in the circumferential direction of the plate portion 31, but preferably protruded from the entire circumferential direction as in the illustrated example. That is, the outer wall portion 32 in the illustrated example has an endless annular shape when viewed from above.
The placement wall portion 33 rises upward from the upper surface of the plate portion 31 on the inner side of the outer wall portion 32. A plurality of mounting wall portions 33 may be provided protruding at a predetermined interval in the circumferential direction of the plate portion 31, but preferably protruding from the entire circumferential direction as in the illustrated example. That is, the mounting wall portion 33 in the illustrated example has an endless annular shape when viewed from above.
The protruding height of the outer wall portion 32 and the protruding height of the mounting wall portion 33 may be the same height, and either one may be higher than the other. Preferably, the protruding height of the outer wall portion 32 is higher than the protruding height of the placement wall portion 33 as in the illustrated example.

  In the illustrated example, the outer wall portion 32 and the placement wall portion 33 have a uniform thickness in the vertical direction. But the outer wall part 32 and the mounting wall part 33 may have a part from which the thickness differs in the up-down direction each independently. For example, the outer wall portion 32 may have a portion that is gradually formed thinner as it goes upward, or may have a portion that is gradually formed thinner as it goes downward. . For example, the outer surface of the upper end portion of the outer wall portion 32 may be formed so as to be inclined inward as it goes upward. In this case, the thickness of the upper end portion of the outer wall portion 32 is gradually increased downward from the upper end, and the upper end portion is a portion formed in a thin shape. Thus, by forming a part of the outer surface of the upper end portion in an inclined shape (in other words, forming an inclined surface on the outer surface of the upper end portion), the bottom member 3 is securely held by the heat-shrinkable tubular film 1. .

The bottom member 3 is made of a material that has higher rigidity than the heat-shrinkable tubular film 1 and does not easily break even when an impact is applied. The material for forming the bottom member 3 is not particularly limited, and examples thereof include synthetic resins and metals, but synthetic resins are preferable.
Examples of the synthetic resin include polyolefin resins such as polyethylene and polypropylene; polyester resins; polystyrene resins; vinyl chloride resins; polycarbonate resins; polyamide resins; Moreover, when forming the bottom member 3 with a synthetic resin, a non-foamed synthetic resin is used, but a foamed hard synthetic resin may be used.
The bottom member 3 may be made of the same material as the outer member 2 or may be made of a different material. Since the bottom member 3 and the outer member 2 are made of separate and independent members, it is easy to form both of them from different materials. For example, the bottom member 3 may be formed of a polyethylene resin and the outer member 2 may be formed of a polypropylene resin.

The bottom member 3 using a synthetic resin is typically formed by a molding method such as injection molding.
The thickness of the bottom member 3 is not particularly limited, but if the thickness is too small, the function of protecting the bottom of the container is lowered, and if it is too large, it is not preferable from the viewpoint of cost effectiveness. From this viewpoint, the thicknesses of the plate portion 31, the outer wall portion 32, and the placement wall portion 33 are each independently preferably 0.2 mm to 3 mm, and more preferably 0.4 mm to 2 mm.

<Manufacturing method of outer packaging for container>
The container exterior body is obtained by causing the heat-shrinkable tubular film 1 to hold the outer member 2 and the bottom member 3.
For example, FIG. 3 has shown one process in the manufacturing method of the container exterior body of this embodiment. However, the container outer body of the present invention is not limited to the one obtained by the following manufacturing method.
As shown in FIG. 3, the top surface portion 81, a side surface portion 82 that extends continuously downward from the periphery of the top surface portion 81 and conforms to the shape of the inner peripheral surface portion of the main portion 21 of the outer member 2, and the side surface portion A pedestal 8 having a step portion 83 projecting radially outward from the lower end of 82 is prepared. The top view shape of the top surface portion 81 of the pedestal 8 is formed in substantially the same shape as the top view shape of the sub portion 22 of the outer member 2 and the plate portion 31 of the bottom member 3.
The side surface portion 82 is formed in a cylindrical shape of a straight body having an outer peripheral length slightly smaller than the inner peripheral length of the main portion 21 of the outer member 2.

The outer member 2 is fitted into the side surface portion 82 of the pedestal 8 with the opening end of the external member 2 facing down. The main portion 21 and the sub-portion 22 of the fitted outer member 2 are fitted to the side surface portion 82 and the top surface portion 81 of the pedestal 8 and do not move up and down and left and right.
Next, while the inner side of the outer wall portion 32 of the bottom member 3 is engaged with the concave portion 222 of the sub-portion 22 of the outer member 2, the protruding end of the mounting wall portion 33 of the bottom member 3 is made to be Contact the outer surface. In this way, the outer member 2 and the bottom member 3 are set at predetermined positions on the base 8. In addition, since the side part 82 of the base 8 is longer than the length of the outer member 2 in the vertical direction, the lower part of the side part 82 of the base 8 is exposed even after the outer member 2 is set.

Next, the heat-shrinkable tubular film 1 is fitted to the outside of the outer member 2 and the bottom member 3, and one open end (first open end) of the heat-shrinkable tubular film 1 is set to the step portion 83 of the base 8. Abut. The position of the step portion 83 is such that the opening end (second opening end) on the opposite side of the heat-shrinkable tubular film 1 is above the bottom member 3 when the first opening end is applied to the step portion 83. And the up-down direction length of the heat-shrinkable cylindrical film 1 is set.
And by heat pre-molding the heat-shrinkable tubular film 1, the periphery of the second opening end of the heat-shrinkable tubular film 1 becomes the peripheral portion of the plate portion 31 of the bottom member 3 as shown in FIG. 4. The other portions of the heat-shrinkable tubular film 1 are in close contact with the outer wall portion 32 of the bottom member 3, the main portion 21 of the outer member 2, and the exposed side surface portion 82 of the base 8.
Finally, by pulling out the heat-shrinkable tubular film 1 and the like from the pedestal 8, the container outer package A is obtained.

<Container for container>
As shown in FIG. 5, the container outer package A includes a preliminarily formed (preliminarily heat-shrinkable) heat-shrinkable tubular film 1 and a bottom portion held at the lower end of the heat-shrinkable tubular film 1. The material 3 and the bottom member 3 are independent members, and have an outer member 2 held on the inner peripheral surface portion of the heat-shrinkable tubular film 1.

In the bottom member 3 disposed on the lower side, the lower end portion of the heat-shrinkable tubular film 1 is tightly adhered to the peripheral portion of the plate portion 31 and the outer wall portion 32. The bottom member 3 is held inside the lower end portion of the heat-shrinkable tubular film 1 by strongly adhering the lower end portion of the bent heat-shrinkable tubular film 1. The outer member 2 is held on the inner peripheral surface portion of the heat-shrinkable tubular film 1 by strongly adhering the heat-shrinkable tubular film 1 to the outer surface of the main portion 21. Further, the heat-shrinkable tubular film 1 is partially reduced in diameter corresponding to the opening end of the main portion 21 to lock the opening end of the main portion 21 and more than the opening end. It extends upward. Since the opening end of the main portion 21 is locked to a part of the heat-shrinkable tubular film 1, the outer member 2 will not accidentally fall out of the heat-shrinkable tubular film 1.
A portion of the heat-shrinkable tubular film 1 that extends upward from the opening end of the main portion 21 of the outer member 2 is composed of only the heat-shrinkable tubular film 1.

<Use of outer packaging for containers and containers with outer packaging>
A container with an exterior body is obtained by attaching the container exterior body A to the container.
As shown in FIGS. 6 and 7, the container 9 includes a bottom portion 91 and a body portion 92 formed above the bottom portion 91 in order from the bottom. The container 9 is configured such that it can stand on its bottom 91.
Specifically, the container 9 includes a bottom portion 91, a trunk portion 92 raised upward from the bottom portion 91, a shoulder portion 93 that is formed above the trunk portion 92 and has an outer peripheral length that gradually decreases toward the top. It has a neck portion 94 formed above the shoulder portion 93, a loading / unloading portion 95 that is an opening portion of the neck portion 94, and a lid portion 96 that covers the loading / unloading portion 95.

The top view shape of the bottom 91 is not particularly limited, and examples thereof include a substantially circular shape, a substantially elliptical shape, and a substantially polygonal shape such as a substantially rectangular shape. The illustrated container 9 has a substantially circular bottom 91. The outer surface of the bottom portion 91 may be substantially flat as in the illustrated example, or may have a concave portion partially, although not particularly illustrated. The bottom 91 having a partially recessed portion is generally exemplified by a substantially domed shape having a substantially flat peripheral edge and a central portion surrounded by the peripheral edge recessed upward.
The shape of the body portion 92 is not particularly limited, and examples thereof include a substantially cylindrical shape such as a substantially cylindrical shape, a substantially elliptical tubular shape, and a substantially rectangular tubular shape. The illustrated container 9 has a substantially cylindrical body 92. The outer surface of the body portion 92 may be a straight body shape or may be partially reduced in diameter. The body portion 92 in the illustrated example has a straight body shape.
The shoulder portion 93 is formed continuously from the upper end of the body portion 92, and is reduced in diameter toward the upper side while being curved in an arc shape in a longitudinal sectional view.
The insertion / removal portion 95 is an opening portion of the neck portion 94 formed continuously with the shoulder portion 93 and is closed by a lid portion 96. The lid 96 is not particularly limited as long as it can close the entrance / exit 95, and may be detachable from the neck 94 or may not be easily removed from the neck 94. Examples of the lid portion 96 that can be attached to and detached from the neck portion 94 include those that are attached to the neck portion 94 by screw action, and those that are attached to the neck portion 94 by concave and convex fitting. The lid portion 96 in the illustrated example is strongly fitted to the neck portion 94 and cannot be easily removed from the neck portion 94.

The material of the container 9 is not particularly limited, but a container that is relatively easily damaged by an impact is preferable because it can be protected by mounting the container outer package A of the present invention. As such a container 9, what has at least the bottom part 91, the trunk | drum 92, and the shoulder part 93 formed with glass or earthenware is mentioned. Preferably, a container in which at least the bottom 91, the trunk 92, and the shoulder 93 are made of transparent or opaque glass (more preferably, transparent glass) is used.
Items stored in the container 9 are not particularly limited, and examples thereof include pharmaceuticals, foods, and beverages. Preferably, a medical container in which a medicine is stored is used. In the example of illustration, the vial which is an example of a medical container is illustrated. In each of the drawings showing the container 9, the storage items stored in the container are not shown.

As shown in FIG. 8, the container 9 with the exterior body as shown in FIGS. 9 and 10 is obtained by inserting the container 9 inside the exterior body A for containers and heating the exterior body A for containers. .
Specifically, as shown in FIG. 8, the container 9 is placed inside the container casing A so that the outer surface of the bottom 91 of the container 9 is placed on the sub-portion 22 of the outer member 2 of the container casing A. insert. Since the inner peripheral length of the main portion 21 of the outer member 2 is substantially the same as (or larger than) the outer peripheral length of the barrel portion 92 of the container 9, the container 9 does not interfere with the outer member 2 and is the sub-portion. 22 In this state, the heat-shrinkable tubular film 1 of the container outer body A is heated. By heating, the heat-shrinkable tubular film 1 shrinks in the circumferential direction so that the diameter thereof is reduced, and the shrinkage force is applied to the main portion 21 of the outer member 2 from the outside. Due to the contraction force, as shown in FIG. 11, each small partition portion 211 (small partition portion 211 indicated by a two-dot chain line) standing upright before heating is pressed inward and bent, and from the plurality of small partition portions 211. The variable region is reduced in diameter and is in contact with or close to the shoulder portion 93 of the container 9. In addition, the width | variety of the notch part 4 becomes small corresponding to the inner side deformation | transformation of each small division part 211. FIG. Further, each of the small partition portions 211 is curved substantially along the curved surface of the shoulder portion 93 of the container 9 so as to be in contact with or close to the shoulder portion 93.

  Of the heat-shrinkable tubular film 1 of the outer package A for containers, a portion not corresponding to the bottom member 3 and the outer member 2 (a portion extending upward from the opening end of the main portion 21) is heat-shrinked, That portion directly adheres to the upper portion of the shoulder portion 93 of the container 9. The heat-shrinkable tubular film 1 constituting the container outer body A is preliminarily formed by heating as described in the above section <Method for producing container outer body>. Furthermore, it heat shrinks.

  In addition, the container B with an exterior body is not restricted to the manufacturing method using the exterior body A for containers obtained by preforming the heat-shrinkable film 1 as described above. For example, the container B with the exterior body is obtained by setting each member constituting the exterior body for the container at a predetermined position of the container 9 and heat-shrinking the heat-shrinkable tubular film before heating (before preforming). You can also. Specifically, the bottom member 3 is disposed below the bottom portion 91 of the container 9, the outer member 2 is inserted into the body portion 92 of the container 9, and a heat-shrinkable tubular shape before heating from the outside of the outer member 2. After covering with the film 1, the said container B with an exterior body can also be manufactured by heating this.

In the obtained container B with the outer package, the bottom 91 of the container 9 is covered with the sub-portion 22 and the bottom member 3 of the outer member 2, and the lower part of the body 92 and the shoulder 93 of the container 9 is the outer member 2. The main part 21 is covered. The lower portion of the shoulder portion 93 is an arcuate section that is continuous with the upper end of the trunk portion 92 (the boundary between the trunk portion 92 and the shoulder portion 93). The lower portion of the shoulder portion 93 is the lower portion of the outer member 2. The main region 21 is covered with a variable region (a plurality of small sections 211).
The bottom member 3 and the outer member 2 are pressed from the outside by the heat-shrinkable tubular film 1 after heat shrinkage which is in close contact with the outer surface of the shoulder portion 93 of the container 9 from the outer surface of the bottom member 3 and the outer member 2. 9 is fixed.

Even if the container B with an exterior body according to the present invention in which the bottom member 3 is disposed on the bottom 91 of the container 9 and the outer member 2 is disposed on the body 92 of the container 9, the container 9 is damaged even if it collides with a foreign object. Can be prevented.
Further, since the variable region of the outer member 2 is in contact with or close to the shoulder portion 93 of the container 9 due to the contraction force of the heat-shrinkable tubular film 1, the position of the outer member 2 is favorably fixed with respect to the container 9. .
In the container outer package A of the present invention, a part of the main portion 21 of the outer member 2 can be deformed so as to be bent inward by the contraction force of the heat-shrinkable tubular film 1. Even for the container 9 smaller than the inner peripheral length of the portion 21, a part of the main portion 21 is in contact with or close to the container 9 and can be mounted satisfactorily. The container outer package A of the present invention that is bent and deformed inward by the contraction force of the heat-shrinkable tubular film 1 can be easily inserted into the container 9 and after the heat-shrinkable tubular film 1 is heat-shrinked. The at least part of the outer member 2 is in contact with or close to the container 9. Since the container outer body A can accommodate several types of containers 9 having different sizes, the manufacturing cost of the container B with the outer body can be suppressed.

In particular, the container exterior body A of the present embodiment can effectively prevent the container 9 from being damaged because the variable region of the main portion 21 of the outer member 2 is in contact with or close to the shoulder portion 93 of the container 9.
Specifically, regarding the container 9, when the mechanical strength of the body 92 and the shoulder 93 is compared, the body 92 is larger than the strength of the shoulder 93 (the shoulder 93 is arcuate from the boundary with the body 92. Because it has a three-dimensional curved surface). If the variable region of the main portion 21 is in contact with or close to the lower portion of the shoulder portion 93 of the container 9 as in the present embodiment, for example, even if the outer container B is dropped, the shoulder portion 93 is directly It is possible to effectively prevent damage from the shoulder portion 93 of the container 9 having a relatively low strength without hitting the floor surface.

<Modification of First Embodiment>
Although the outer member 2 of the first embodiment has the main part 21 and the sub part 22, for example, as shown in FIG. 12, the outer member 2 does not have the sub part 22 and has the main part 21. Also good.
Moreover, in the said 1st Embodiment, although the outer member 2 which has the notch part 4 with the comparatively short length of an up-down direction was illustrated, for example, as shown in FIG. 13, the length of an up-down direction is comparatively long The outer member 2 having the portion 4 may be used.
Furthermore, in the container B with an outer package according to the first embodiment, the variable region of the main portion 21 is in contact with or close to the shoulder portion 93 of the container 9. For example, as shown in FIG. May be bent inward by the shrinkage force of the heat-shrinkable tubular film 1 and may be in contact with or close to the body 92 of the container 9. Such a container B with an exterior body can be obtained by making the vertical length of the main portion 21 substantially the same as or shorter than the vertical length of the trunk portion 92 of the container 9.

  Hereinafter, the second embodiment of the present invention will be described. In the description, mainly the configurations and effects different from those of the above-described embodiments will be described. A description of the configuration and the like may be omitted (the same applies to the third and subsequent embodiments).

[Second Embodiment]
The second embodiment is characterized by using an outer member in which a continuous cut portion is formed from the upper end to the lower end.

<Outer member>
As shown in FIGS. 15 and 16, the outer member 5 of the present embodiment is a cylindrical member that is attached to the body of the container, and a part of the cylindrical member extends from the upper end 5 a to the lower end 5 b. A connected cut portion 6 is formed. In other words, the outer member 5 is formed of a cylindrical member that is partly divided into left and right by the cut portion 6 in front view. Hereinafter, in order to distinguish from the cut portion 4 of the first embodiment in terms of terms, the cut portion 6 that continues from the upper end 5a to the lower end 5b is referred to as a “divided cut portion”.

Specifically, the outer member 5 of the present embodiment is formed of a cylindrical member as a whole, except for the dividing cut portion 6. The outer member 5 in which the continuous cut portion 6 is formed from the upper end 5a to the lower end 5b of the cylindrical member can be changed so that the entire outer member 5 contracts in the circumferential direction. The entire outer member 5 of the present embodiment is a variable region.
The cylindrical shape of the external member 5 may be a straight barrel shape, or may be a cylindrical shape having a reduced diameter portion whose inner peripheral length gradually decreases from the first side to the second side in the vertical direction.
The outer member 5 in the illustrated example is formed in a cylindrical shape having a reduced diameter portion, and in particular, is formed in a substantially inverted truncated cone cylindrical shape, which is a cylindrical shape whose entirety is a reduced diameter portion.
The overall cylindrical shape, which is a reduced-diameter portion, generally has an inner circumference extending from one opening end (the opening end on the first side in the vertical direction) to the other opening end (the opening end on the second side in the vertical direction). The length is gradually decreasing.
The outer member 5 having a reduced diameter portion has a portion having a minimum inner circumferential length. In the present embodiment, the minimum value of the inner peripheral length of the outer member 5 is substantially the same as or larger than the outer peripheral length of the trunk portion 92 of the container 9.

The outer member 5 having the reduced diameter portion may be arranged with the side with the smaller inner peripheral length (second side in the vertical direction) on the lower side, or with the side on the upper side.
In the example of illustration, the outer member 5 is arrange | positioned by making the side with a small inner periphery length down. In this arrangement, the outer circumferential length of the outer member 5 gradually increases toward the upper side (the large diameter region of the outer member 5 is on the upper side and the small diameter region is on the lower side).
The degree of gradual decrease in the inner circumferential length of the reduced diameter portion can be expressed by, for example, an angle α formed by the inner surface of the outer member 5 with respect to the vertical direction L in the longitudinal sectional view shown in FIG. The degree of gradual reduction of the inner peripheral length of the reduced diameter portion is not particularly limited, but if it is too large, when the outer member 5 is attached to the body of the container, the large diameter region of the outer member 5 becomes the body of the container. May be too far away from From this point of view, the angle α formed by the inner surface of the outer member 5 with respect to the vertical direction L (the degree of gradual decrease in the inner peripheral length of the reduced diameter portion) is preferably more than 0 degree and 3 degrees or less, as shown in FIG. 5 degrees-1.5 degrees are more preferable.

The dividing cut portion 6 is formed at one place. For example, as shown in the drawing, the dividing cut portion 6 may be formed to extend substantially in parallel with the vertical direction from the upper end 5a to the lower end 5b, or may be inclined with respect to the vertical direction from the upper end 5a to the lower end 5b. It may be formed.
Moreover, the dividing cut | notch part 6 may be extended linearly like the example of illustration, or may be extended and formed non-linearly, such as arc shape or zigzag shape.
The width of the dividing notch 6 may gradually decrease or gradually increase from the upper end 5a toward the lower end 5b, or the width may be uniform from the upper end 5a to the lower end 5b. In the example of illustration, the parting cut part 6 which has a uniform width | variety in the up-down direction is represented.
Furthermore, as shown in FIG. 16B, the opposing side end portions 6a, 6a that define the dividing cut portion 6 are formed in a straight line shape extending in the radial direction of the outer member 5 in a sectional view.

The width of the cut portion 6 is set as appropriate, but if it is too small, the outer member 5 may not be sufficiently shrunk when the heat-shrinkable tubular film 1 is heat-shrinked. In particular, the surface area of the outer member 5 is reduced. From such a viewpoint, the width of the dividing cut portion 6 is preferably 2 mm to 20 mm, and more preferably 3 mm to 10 mm. In addition, the width | variety of the said cutting part 6 says the length corresponding to the circumferential direction of the outer member 5. FIG. In the case where the width of the divided cut portion 6 is not uniform in the vertical direction, the width of the divided cut portion 6 means its maximum value.
In the present embodiment, the heat-shrinkable tubular film 1 and the bottom member 3 are the same as those in the first embodiment.

<Manufacturing method of outer packaging for container>
The container exterior body A of the present embodiment is also obtained by holding the outer member 5 and the bottom member 3 on the heat-shrinkable tubular film 1.
As shown in FIG. 17, the top surface portion 81, the side surface portion 82 that continuously extends from the periphery of the top surface portion 81 and that conforms to the shape of the inner peripheral surface portion of the outer member 5, and the lower end of the side surface portion 82 A pedestal 8 having a step portion 83 projecting in the radially outward direction is prepared. The top view shape of the top surface portion 81 of the base 8 is formed in substantially the same shape as the top view shape of the plate portion 31 of the bottom member 3.
The side surface portion 82 is formed in a substantially truncated cone shape whose outer peripheral length gradually decreases as it goes upward so as to match the shape of the inner peripheral surface portion of the outer member 5. Preferably, the side surface portion 82 is inclined at the same angle as the angle formed by the inner surface of the outer member 5 with respect to the cylinder axis direction in a front view. That is, the side surface portion 82 has a substantially truncated cone shape whose outer peripheral length gradually decreases as it goes upward, and is formed in a substantially truncated cone shape that gradually decreases to the same extent as the inner peripheral surface portion of the outer member 5. Further, the length of the side surface portion 82 in the vertical direction is larger than the length of the outer member 5 in the cylinder axis direction.

The outer member 5 is fitted into the side surface portion 82 of the pedestal 8 with the first side in the cylinder axis direction of the outer member 5 (the side with the larger inner peripheral length) facing down. The fitted outer member 5 fits to the side surface portion 82 of the base 8 and does not move up and down and left and right.
Next, the protruding end of the mounting wall portion 33 of the bottom member 3 is brought into contact with the top surface portion 81 of the pedestal 8 while the inner side of the outer wall portion 32 of the bottom member 3 is hooked on the upper end portion of the side surface portion 82 of the pedestal 8. Let In this way, the outer member 5 and the bottom member 3 are set at predetermined positions on the base 8. In addition, since the side part 82 of the base 8 is longer than the length of the outer member 5 in the axial length direction, the lower part of the side part 82 of the base 8 is exposed even after the outer member 5 is set.

Next, the heat-shrinkable tubular film 1 is fitted to the outside of the outer member 5 and the bottom member 3, and one open end (first open end) of the heat-shrinkable tubular film 1 is set to the step portion 83 of the base 8. Abut. The position of the step portion 83 is such that the opening end (second opening end) on the opposite side of the heat-shrinkable tubular film 1 is above the bottom member 3 when the first opening end is applied to the step portion 83. And the up-down direction length of the heat-shrinkable cylindrical film 1 is set.
And by heat pre-molding the heat-shrinkable tubular film 1, the periphery of the second opening end of the heat-shrinkable tubular film 1 becomes the periphery of the plate portion 31 of the bottom member 3 as shown in FIG. The other parts of the heat-shrinkable tubular film 1 are in close contact with the outer wall portion 32 and the outer member 5 of the bottom member 3 and the exposed side surface portion 82.
Finally, by pulling out the heat-shrinkable tubular film 1 and the like from the pedestal 8, the container outer package A is obtained.
By using the outer member 5 having a reduced diameter portion as in the present embodiment, the container outer package A can be easily pulled out from the base 8.

<Container for container>
As shown in FIG. 18, the container outer body A of the present embodiment has a heat-shrinkable tubular film 1 that is preformed (preliminarily heat-shrinked) and a lower end portion of the heat-shrinkable tubular film 1. It has a held bottom member 3 and an outer member 5 held on the inner peripheral surface portion of the heat-shrinkable tubular film 1.
In the bottom member 3 disposed on the lower side, the lower end portion of the heat-shrinkable tubular film 1 is tightly adhered to the peripheral portion of the plate portion 31 and the outer wall portion 32.
The outer member 5 having a reduced diameter portion is held by the heat-shrinkable tubular film 1 with the side having the smaller inner peripheral length (the opening end side on the second side) facing down.
Further, the heat-shrinkable tubular film 1 is partially reduced in diameter corresponding to the opening end on the first side of the outer member 5 (the upper end 5a of the outer member 5), so that the opening end on the first side is reduced. It is locked and extends upward from its open end. Since the opening end on the first side of the external member 5 is locked to a part of the heat-shrinkable tubular film 1, the outer member 5 does not accidentally fall out of the heat-shrinkable tubular film 1.
Of the heat-shrinkable tubular film 1, the portion extending upward from the opening end on the first side of the outer member 5 is composed of only the heat-shrinkable tubular film 1, and this portion is viewed in a longitudinal section. In FIG. 2, the outer member 5 is inclined and extended at the same angle as the angle formed by the inner surface of the outer member 5 with respect to the cylinder axis direction.

<Use of outer packaging for containers and containers with outer packaging>
A container B with an exterior body is obtained by mounting the container exterior body A on the container 9.
For example, as shown in FIG. 19, by inserting the container 9 inside the container outer package A and heating the container outer package A, a container B with an outer package as shown in FIG. 20 is obtained.
Specifically, as illustrated in FIG. 19, the container 9 is mounted on the container 9 such that the outer surface of the bottom 91 of the container 9 is placed on the protruding end of the mounting wall portion 33 of the bottom member 3 of the container outer body A. Insert inside A. Since the outer member 5 has a substantially inverted truncated cone shape with the side having the larger inner peripheral length facing upward, the container 9 can be easily inserted. Further, since the minimum value of the inner peripheral length of the outer member 5 is substantially the same as (or larger than) the outer peripheral length of the trunk portion 92 of the container 9, the container 9 can be Contact material 3. In this state, the heat-shrinkable tubular film 1 of the container outer body A is heated. By heating, the heat-shrinkable tubular film 1 shrinks in the circumferential direction so that the diameter thereof is reduced, and the shrinkage force is applied to the outer member 5 from the outside. Due to the contraction force, as shown in FIG. 21 (the outer member before deformation is indicated by a two-dot chain line), the cylindrical outer member 5 is bent so as to reduce the diameter, and at the same time, the width of the dividing cut portion 6 is reduced. The outer member 5 is in contact with or close to the body 92 of the container 9. In the present embodiment, since the outer member 5 is formed in a substantially inverted truncated cone shape, as shown in FIG. 21, the outer member 5 has an upper side with a large inner peripheral length and a lower side with a small inner peripheral length.
