Description

  The present invention relates to a bottle-break preventing packaging container and a packaging method for a bottle-break preventing packaging container for preventing a container such as a vial container from breaking due to vibration or impact.

  Conventionally, as shown in FIG. 23, a container 100 used for a vial container or the like is generally made of glass. When the container 100 is placed on the container 100, the container 100 is placed too strongly, or is shocked by vibration or dropping during transportation. If the bottle is broken, the glass piece 101 and the contents 102 inside the container may be scattered.

  For this reason, the bottom of the vial container is covered with a bottom sticker, the side is covered with a sleeve, etc., and the sleeve is brought into close contact with the vial container by heat shrinkage, so that the periphery of the vial container is kept hygienic and added to the container. There is a technique for preventing a broken bottle from impact (Patent Document 1).

Special table 2008-509864 gazette

  However, in the above configuration, the bottom portion of the vial container is merely provided with a bottom sticker, and the vial container cannot be sufficiently protected from excessive impact.

  In view of the circumstances described above, the present invention is to provide a bottle-break preventing packaging container and a packaging method for the bottle-break preventing packaging container that prevent the container from breaking due to an impact or the like.

Means for Solving the Problems and Effects of the Invention

In order to solve the above problem, the bottle-breakage-proof packaging container of the present invention is
A container having a trunk part and a bottom part constituting the lower end part of the trunk part, an end surface of the bottom part being a bottom surface, and an opening formed on the upper side of the trunk part being covered with a lid part;
A cushioning member positioned so as to be fitted or butted against the bottom of the container and protruding downward from the bottom surface to protect the container;
A heat shrink film wrapped by heat shrink so as to cover at least the periphery of the joint of the container and the buffer member;
It is characterized by providing.

  The container described here is typically a cylindrical container such as a vial container whose upper opening is covered with a lid, but is not limited to a vial container. Further, the bottle-break preventing packaging container refers to a container in which a container such as a vial container and a buffer member formed of, for example, a resin are covered with a heat shrink film that shrinks by heat shrink. The heat shrinkable film includes not only a film that shrinks simply by heat shrinkage, but also includes a heat shrinkable label in which the front surface or back surface of the film is a printing surface and the back surface of the film has or does not have a glue layer. A typical example is a shrinkage label.

  According to the present invention, a buffer member is provided below a container such as a vial container. Further, since the container and the buffer member are covered with a heat shrink film at least around the joint portion thereof, It becomes possible to integrate the buffer member. If integrated in this way, when an excessive impact is generated in the container, the buffer member can absorb the impact and hold the container, and the effect of preventing bottle breakage is enhanced.

  In addition, the heat shrink film wraps in a range over the entire height of the container including the buffer member, with the upper end going around the top surface of the lid of the container and the lower end going around the bottom surface of the buffer member.

  According to this, since it is possible to cover from the lid portion above the container to the lower buffer member with the heat shrink film, the sealing performance of the container is improved, and the vial container can be handled hygienically. In addition, even if the container is damaged due to excessive impact, the glass and the contents inside are difficult to scatter and are safe.

  In addition, the container has a shape with a narrowed shoulder portion from the middle of the trunk portion to the upper lid portion, and the heat-shrink film has an upper end on the shoulder surface of the shoulder portion and a lower end on the bottom surface of the cushioning member. Wrap around and wrap the area from the shoulder of the container to the bottom of the cushioning member.

  The heat-shrinkable film covers an area in which the upper end is applied to the side surface of the body portion, the lower end wraps around the bottom surface of the buffer member, and extends from the body portion of the container to the bottom surface of the buffer member.

  Further, the container has a shape with a narrowed shoulder portion extending from the middle of the trunk portion to the upper lid portion, and the heat shrink film has an upper end on the shoulder surface of the shoulder portion and a lower end on the side surface of the cushioning member. It covers and covers the range from the shoulder of the container to the side of the buffer member.

  According to these, when the shoulder part of the shape narrowed above the container is formed, the heat shrink film is applied to the shoulder surface of the shoulder part, and the heat shrink film is difficult to come off. Furthermore, since the top of the lid is not packaged, the lid can be easily opened and closed and the amount of heat-shrinkable film used can be reduced.

  Moreover, when covered with the heat-shrink film so as to go around to the bottom surface of the buffer member, the heat-shrink film prevents the buffer member from coming out of the container. However, since a heat-shrinkable film is used, even if only the position on the side surface of the container body and the side surface of the buffer member is covered, as long as the container shrinks sufficiently, It is possible to integrate the member, and the amount of heat shrink film used can be reduced.

  The buffer member has a side wall that fits or contacts the bottom of the container, a bottom wall formed at a lower portion of the side wall, and a stopper that extends from the side wall or the bottom wall and contacts the bottom of the container.

  According to this, since the side wall of the buffer member is fitted or in contact with the bottom of the container, it is possible to prevent lateral displacement. Moreover, since the stopper which extends from a side wall or a bottom wall and contacts the bottom part of a container is formed, the fitting margin of a container can be determined uniquely.

  Moreover, the taper part which diameter-expands is formed in the container side of the side wall of a buffer member, and a container fits or contacts the taper part.

  According to this, it is easy to attach a container and a buffer member by a taper part, and it is easy to form the outer surface continuous in the junction part of a container and a buffer member.

  Further, the stopper of the buffer member is formed inside the side wall of the buffer member, and a hollow portion is formed between the bottom of the container and the bottom wall or the grounding surface of the buffer member.

  According to this, since the hollow part is formed in the buffer member, when an excessive impact is applied to the vial container, the hollow part serves as a cushion and the impact resistance is improved.

  Further, after the stopper protrudes laterally from the inner surface of the side wall, it is formed in an annular shape extending upward, and its upper end surface comes into contact with the bottom surface of the container.

  According to this, since the upper end surface of the stopper is in contact with the bottom surface of the container, the fitting margin of the container is uniquely determined on the annular line. Further, since the stopper protrudes in the lateral direction and then extends upward, the cross section is L-shaped, and the portion can absorb the impact.

  Specifically, when an impact is applied to the container, the upper end surface of the stopper that contacts the bottom surface of the container bends inward, and the tapered portion bends outward along the corner of the container. According to this, it is possible to further absorb the impact applied to the container.

  In addition, the hollow portion receives the contents inside the container in the hollow portion when the container is broken. According to this, even if the container is damaged, the internal contents do not leak out and it is safe.

In addition, the packaging method of the bottle-breakage prevention packaging container of the present invention,
Preparing a container having a trunk part and a bottom part constituting the lower end part of the trunk part, an end surface of the bottom part being a bottom surface, and an opening formed on the upper side of the trunk part being covered with a lid part;
A step of fitting or butting a cushioning member to the bottom of the container;
In that state, after covering the heat shrink film so as to cover at least the periphery of the joint between the body of the container and the buffer member, the process of heat shrinking and closely contacting at least the body of the container and the outer surface of the buffer member;
It is characterized by including.

  According to this, it can package as a packaging container which integrated containers, such as a vial container, and a buffer member with the heat contraction film contracted by heat contraction. And since the buffer member is provided in the bottom part of the container, it can be set as the packaging container strong against the vibration at the time of conveyance, and an excessive impact.

  Moreover, it is good also as a structure which wraps the range over the full height of the container containing a buffer member with a heat-shrink film so that an upper end may go around to the top | upper surface of the cover part of a container, and a lower end may go around to the bottom face of a buffer member.

  According to this, when packaging the range from the cover part of a container to a buffer member, the virgin property of a container is maintained and it is hygienic. Moreover, it is possible to make a packaging container with impact resistance by the buffer member at the bottom of the container. Furthermore, even if the bottle is broken due to an excessive impact, the glass and the internal contents are less likely to scatter and a safe packaging can be achieved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a front view showing a bottle-break preventing packaging container 1 according to the present invention. The broken bottle prevention packaging container 1 includes a vial container (hereinafter also simply referred to as a container) 2, a buffer member 3, and a heat shrink film 5. The container 2 has a barrel portion 2a and a bottom portion 2b (see FIG. 4) constituting the lower end portion of the barrel portion 2a. The end surface of the bottom portion 2b is a bottom surface 2b1 (see FIG. 4), and a cylindrical barrel. An opening 2d formed on the upper side of the portion 2a is covered with a lid portion 4 including a cap portion 4a and a sealing portion 4b. Moreover, it is located so that it may face | match with respect to the bottom part 2b of the container 2, The buffer member 3 which protrudes below from the bottom face 2b1 of the container 2 and protects the container 2 is provided. Further, as can be seen from the plan view shown in FIG. 2 and the bottom view shown in FIG. 3, the upper end turns around the top surface 4 a 1 of the lid 4 (cap part 4 a) of the container 2, and the lower end turns around the bottom surface 3 b 1 of the buffer member 3. The range over the entire height of the container 2 including the buffer member 3 is covered with a heat-shrinkable heat-shrink film with a display (heat-shrink label) 5. A paste layer is formed on the back surface of the heat shrinkable film 5 so that the paste surface adheres to the surface of the container 2 or the buffer member 3 during heat shrinkage. In addition, on the front surface or the back surface of the heat shrink film 5, a print region 6 on which information about the contents inside is printed is formed. Here, the cap part 4a can be removed by cutting the perforation 5a of the heat shrink film 5 provided in the vicinity of the lid part 4.

  As shown in FIG. 4 as an AA sectional view of FIG. 1, the container 2 has a body portion 2 a extending upward from the bottom portion 2 b, and is further constricted from the middle of the body portion 2 a to the upper lid portion 4. The shoulder 2c has an opening 2d. Such a medical vial container 2 is generally made of glass, and contents such as a chemical solution are injected into the interior 2e.

  The lid part 4 is formed of a cap part 4a, a sealing part 4b, and a sealing plug 4c, and the opening part 2d of the container 2 is plugged with a sealing plug 4c formed of an elastic body, and the surroundings are made of metal. The sealing part 4b made of is fixed. Furthermore, the cap part 4a is provided so that the upper surface of the sealing part 4b and the sealing stopper 4c may be covered. When using, the cap part 4a is removed, and a syringe or the like is used to penetrate the sealing plug 4c with the tip of the needle and extract the internal chemical solution.

  The buffer member 3 has a side wall 3 a formed so as to be continuous with the body portion 2 a of the container 2, and a bottom wall 3 b is provided below the side wall 3 a. And it has the stopper 3c extended from the side wall 3a and contacting the bottom face 2b1 of the container 2. FIG. Note that a general resin is used as the material of the buffer member 3.

  The heat shrink film 5 covers the periphery of the container 2 and the buffer member 3 as shown in FIG. Specifically, as shown in FIG. 2, the upper end wraps around a part of the top surface 4 a 1 of the lid portion 4 (cap portion 4 a) of the container 2, and the shoulder portion 2 c, the trunk portion 2 a, and the side wall 3 a of the buffer member 3 are connected. Covering. Furthermore, as shown in FIG. 3, the lower end wraps around a part of the bottom surface 3 b 1 of the buffer member 3, and covers a range covering the entire height of the container 2 including the buffer member 3. It should be noted that the thickness of the heat shrink film 5 is exaggerated for easy understanding of the description, and is actually much thinner than the thickness of the container 2.

  The buffer member 3 will be described in detail with reference to FIGS. 5, 6, and 7. As shown in the plan view of FIG. 5, the buffer member 3 has a circular shape, similar to the shape of the bottom 2 b of the container 2. Further, as shown in the CC cross-sectional view shown in FIG. 6 and the BB partial enlarged view shown in FIG. 7A, the diameter increases toward the top of the side wall 3a (from the inside to the outside as it goes upward). (D2> d1). The tapered portion 3d is formed at a position corresponding to the corner 2f of the container 2. From the middle of the side wall 3a, a flange portion 3f is formed from the inner surface of the side wall 3a to the inside in the lateral direction, and an annular stopper 3c extending further upward is formed. The upper end surface 3c1 of the stopper portion 3c comes into contact with the bottom surface 2b1 of the container 2. The stopper 3c includes the flange portion 3f. The stopper 3c forms a hollow portion 3e between the bottom 2b of the container 2 and the bottom wall 3b of the buffer member 3 (between the bottom surface 2b1 of the container 2 and the bottom surface 3b1 (grounding surface) of the buffer member 3). Yes.

  Here, since the taper portion 3d of the buffer member 3 is in a positional relationship corresponding to the corner portion 2f of the container 2, it is easy to attach (fit easily) when the buffer member 3 is attached to the container 2. Furthermore, since the tip of the taper portion 3d is formed at a position higher than the upper end surface 3c1 of the stopper 3c, lateral displacement or the like is less likely to occur during fitting or after mounting.

  Further, the buffer member 3 is provided with a stopper 3c. Since the upper end surface 3c1 of the stopper 3c is in contact with the bottom surface 2b1 of the container 2, the fitting margin of the container 2 is uniquely high on the annular line. Is determined.

  Further, since the side wall 3a of the buffer member 3 and the body 2a of the container 2 are formed in a straight line so as to be continuous, the buffer member 3 is formed in a width direction as compared with the buffer member 3 formed larger than the bottom 2b of the container 2. Storage of the bottle-break preventing packaging container 1 becomes easy without taking up space.

  Next, a case where an impact is applied to the vial container 2 will be described with reference to FIG. When an impact is applied to the vial container 2 from the state of FIG. 7A, as shown in FIG. 7B, the hollow portion 3e containing air formed in the buffer member 3 serves as a cushion, and the container 2 Can alleviate the impact. Furthermore, since the stopper 3c having an L-shaped cross section is bent inward and the tapered portion 3d is bent outward along the corner 2f of the container 2, the impact can be absorbed more. Here, since the heat shrink film 5 is provided so as to cover the periphery of the joint portion 7 between the body portion 2 a of the container 2 and the buffer member 3, the taper portion 3 d is received by the heat shrink film 5.

  Even if the container 2 breaks due to an excessive impact or the like, the container 2 is covered with the heat shrink film 5, so that the internal chemicals and glass pieces are not scattered. Further, since the buffer member 3 is formed with the hollow portion 3e, even if the internal chemical liquid leaks out, the chemical liquid or the like is stored in the hollow portion 3e, so it is safe without leaking outside. . As described above, according to the present invention, the shock absorbing member 3 and the heat shrinkable film 5 having the hollow portion 3e protect the container 2 from excessive shock such as vibration during transportation of the vial container 2 and dropping of the container 2. The bottle-breakage-proof packaging container 1 having a high bottle-breakage prevention effect can be configured.

  Here, the packaging method of the broken bottle prevention packaging container 1 is demonstrated with reference to FIG. In addition, in FIG. 8, the buffer member 3 is demonstrated as sectional drawing so that the mode may be understood easily. First, as shown in FIG. 8A, a vial container 2 provided with a lid 4 is prepared, and the buffer member 3 is positioned so as to abut against the bottom 2b of the container 2 with respect to the container 2, It attaches so that the container 2 may be protected (FIG.8 (b)).

  As shown in FIG. 8B, when the buffer member 3 is fitted to the bottom 2 of the container 2, the bottom 2b of the container 2 and the stopper 3c of the buffer member 3 come into contact (the bottom 2b1 of the container 2 and the buffer 2). The container 2 and the buffer member 3 are fixed by the upper end surface 3c1 of the stopper 3c of the member 3 contacting. Further, at this time, since the corner portion 2f of the container 2 and the tapered portion 3d of the buffer member 3 are in a corresponding positional relationship, the fitting can be easily performed.

  Then, as shown in FIG. 8C, the heat shrink film 5 is arranged around the container 2 and the buffer member 3, and is covered so as to cover the container 2 and the buffer member 3. In addition, although the shape of the heat shrink film 5 is not specifically shown, it should just have the length and magnitude | size which can cover the container 2 after heat shrink. The heat-shrinkable film 5 is not particularly limited, and is composed of, for example, a styrene resin such as polystyrene, a polyester resin such as polyethylene terephthalate, an olefin resin such as polypropylene, or a thermoplastic resin such as vinyl chloride resin. A film containing one kind or a mixture of two or more kinds can be used.

  And as FIG.8 (d) shows, the heat-shrink film 5 is heat-shrinked, and is closely_contact | adhered to the outer surface of the trunk | drum 2a of the container 2, and the buffer member 3. FIG. Since the paste is adhered to the back surface of the heat shrink film 5, the surface of the body 2a of the container 2 and the surface of the buffer member 3 and the heat shrink film 5 are firmly bonded. In this step, the container 2 and the buffer member 3 are packaged by the heat shrink film 5 to form the broken bottle prevention packaging container 1. Thus, since the heat shrink film 5 covers the body 2a (see FIG. 4) of the container 2 and the joint 7 (see FIG. 7) of the buffer member 3, the container 2 and the buffer member 3 are connected to each other. It can be united. At this time, the bottom wall 3b of the buffer member 3 is arranged in parallel with the bottom 2b of the container 2, and the heat shrink film 5 is packaged horizontally with respect to the bottom wall 3b. Thus, the broken bottle prevention packaging container 1 can be set up vertically.

  And since the cover part 4 from the upper part of the container 2 to the lower buffer member 3 is covered with the heat shrink film 5 in this way, the hermeticity of the container 2 is enhanced and the vial container 2 is handled in a sanitary manner. Can do. In addition, since the buffer member 3 is integrally attached, the container 2 can be protected from being placed too strongly when the container 2 is placed, or from vibration during transportation or impact from dropping. Furthermore, even if the container 2 is damaged due to an excessive impact from the outside, the glass and the contents inside the glass are less likely to be scattered, and the safe bottle-breaking packaging container 1 and its packaging method can be obtained.

  Next, FIG. 9 to FIG. 12 show the broken bottle prevention packaging container 1 in which another form of packaging is made. As shown in FIG. 9, the heat shrink film 5 covers a range from the shoulder surface 2 c 1 of the shoulder portion 2 c of the container 2, the side surface of the trunk portion 2 a, the side wall 3 a of the buffer member 3, and a part of the bottom portion 3 b (bottom surface 3 b 1). You may make it do. In this case, since the shoulder portion 2c of the container 2 serves as a stopper for preventing the removal, the heat-shrinkable film 5 is applied to one side 2c1 of the shoulder portion 2c, is not easily detached, and is not displaced from the container 2. Moreover, since it is not packaged to the top | upper surface 4a1 of the cover part 4, opening and closing of the cover part 4 is easy, and the usage-amount of the heat-shrink film 5 can be reduced.

  Moreover, as shown in FIG. 10, you may make it wrap the heat-shrink film 5 over the side surface of the trunk | drum 2a of the container 2, the side wall 3a of the buffer member 3, and a part of bottom wall 3b (bottom surface 3b1). Since the trunk | drum 2a is formed long compared with the side wall 3a of the buffer member 3, there is no fear that the heat shrink film 5 slips down, and the usage-amount of the shrink film 5 can further be reduced rather than the case of FIG. Further, since the bottom surface 3b1 of the buffer member 3 is covered with the heat shrink film 5, the buffer member 3 is prevented from coming off.

  Further, as shown in FIG. 11, the heat shrink film 5 covers a part of the top surface 4 a 1 of the lid portion 4 (cap portion 4 a), the side surface of the body portion 2 a of the container 2, and the side wall 3 a of the buffer member 3. You may be made to do. When packaged in this way, the buffer member 3 may fall out downward. However, if the heat-shrinkable film 5 is sufficiently contracted, the buffer member 3 is tightened, so that the container 2 and the buffer member 3 can be firmly fixed. . And according to this aspect, since the whole bottom wall 3b (bottom surface 3b1) of the buffer member 3 is in contact with the floor surface, stability when the container 2 is stood on the floor surface is increased. A perforation 5 a is provided at a position corresponding to the shoulder 2 c of the container 2. By forming the perforation 5a at such a position, it is possible to take the upper part from the shoulder 2c of the heat shrink film 5. Therefore, since all the cover part 4 is exposed, it is easy to use and the cover part 4 (cap part 4a) can be easily opened and closed.

  In addition, as shown in FIG. 12, the heat shrink film 5 may be packaged so as to cover the side surface of the body portion 2 a of the container 2 and the side wall 3 a of the buffer member 3. When packaged in this way, the amount of the heat-shrinkable film 5 can be considerably reduced. However, even if it is reduced, it is possible to integrate the container 2 and the buffer member 3 as long as the heat-shrinkable film 5 is sufficiently heat-shrinked.

  In this way, at least the periphery of the joint portion 7 (see FIG. 7) of the body 2a of the container 2 and the buffer member 3 is covered with the heat shrink film 5, and the heat shrink film 5 is thermally shrunk and fixed. It becomes possible to integrate the buffer member 3. And since the buffer member 3 provided with the hollow part 3e can be attached to the downward direction of the container 2 by integrating, it leads to prevention of a broken bottle.

  The modification of the buffer member 3 is shown in FIGS. The buffer member 30 shown in FIG. 13 has a tapered portion 30d formed at a position corresponding to the corner 2f of the container 2 above the side wall 30a. An annular stopper 30c that contacts the bottom surface 2b1 (not shown) of the container 2 below is formed so as to extend vertically from the bottom wall 30b of the buffer member 30 and support the bottom 2b of the container 2. The stopper 30c forms a hollow portion 30e between the bottom 2b of the container 2 and the bottom wall 30b of the buffer member 30. With such a shape, it becomes easy to create a mold or the like when manufacturing the buffer member 30.

  Further, the buffer member 31 shown in FIG. 14 has a tapered portion 31d formed at a position corresponding to the corner portion 2f of the container 2 above the side wall 31a, and a flange portion 31f extends from the side wall 31a toward the inside. A first stopper 31c1 extends upward so as to come into contact with the bottom surface 2b1 (not shown) of the container 2. Further, the second stopper 31c2 extends vertically upward from the vicinity of the center of the bottom wall 31b. In this way, by providing the second stopper 31c2, the strength for supporting the container 2 itself can be increased. At this time, the first stopper 31c1 and the second stopper 31c2 formed in an annular shape are used to form the first hollow portion 31e1 and the second hollow portion 31e2 between the bottom wall 3b of the buffer member 3 and the bottom portion 2b of the container 2. There can be two places to enter, improving shock absorption.

  Further, the buffer member 32 shown in FIG. 15 has a tapered portion 32d formed at a position corresponding to the corner portion 2f of the container 2 above the side wall 32a, and a horizontal portion 32f extends inward from the side wall 32a. It is connected with the side wall part 32a. A stopper 32c is formed on the upper surface of the horizontal portion 32f so as to be in contact with the bottom surface 2b1 (not shown) of the container 2. By adopting such a configuration, the stopper 32c is provided between the bottom wall 32b of the buffer member 32 and the bottom 2b of the container 2 in a total of two locations of the first hollow portion 32e1 and the second hollow portion 32e2 in order from the top. A space can be formed. Since the second hollow portion 32e2 is surrounded by a part of the buffer member 32 in all directions, the internal air can be confined in the space, the air does not leak to the outside due to the impact, and the impact resistance is high. Become.

  Of course, it is possible to use the buffer member 3 for containers other than the vial container 2 as described above, and the shape of the buffer member 3 may be appropriately changed in accordance with the shape of the container.

  Furthermore, the positional relationship of the modification of the container 2 and a buffer member (33-39) is shown in FIGS. As shown in FIG. 16, the side wall 33 a of the buffer member 33 is fitted to the bottom 2 b of the container 2. The upper surface 33c1 of the buffer member 33 and the bottom surface 2b1 of the container 2 are in contact with each other, and the buffer member 33 has a larger diameter as it goes from the upper surface 33c1 to the bottom surface 33b1, and the stability when placed on the floor surface is high. Moreover, since the bottom part 2b of the container 2 should just fit together along the side wall 2a, insertion is easy.

  In the example shown in FIG. 17, the side wall 34a of the buffer member 34 functions as a stopper 34c. That is, the stopper 34 c is formed annularly along the lower side of the corner 2 f of the container 2, and the hollow portion 34 e is formed between the bottom 2 b of the container 2 and the bottom wall 34 b of the buffer member 34.

  In the example shown in FIG. 18, the tapered portion 35 d formed on the upper portion of the side wall 35 a of the buffer member 35 is in contact with the corner portion 2 f of the container 2 to support the container 2. The tapered portion 35d also serves as a stopper 35c and uniquely determines the fitting allowance of the container. A hollow portion 35 e is formed between the bottom portion 2 b of the container 2 and the bottom wall 35 b of the buffer member 35.

  In the example shown in FIG. 19, the tapered portion 36 d formed on the upper portion of the side wall 36 a of the buffer member 36 is in contact with the corner portion 2 f of the container 2. Further, a stopper 36c extending upward from the bottom wall 36b contacts the bottom surface 2b1 of the container 2 to uniquely determine the fitting allowance. A first hollow portion 36e1 and a second hollow portion 36e2 are formed between the bottom 2b of the container 2 and the bottom wall 36b of the buffer member 36.

  In the example shown in FIG. 20, the flange portion 37 f extends inward from the middle of the side wall 37 a of the buffer member 37. The upper surface of the flange portion 37f contacts the bottom surface 2b1 of the container 2 and functions as a stopper 37c. Since the side wall 37a is annularly disposed at a position corresponding to the bottom 2b (body portion 2a) of the container 2, the side wall 37a can be easily fitted to the container 2. A hollow portion 37 e is formed between the bottom portion 2 b of the container 2 and the bottom wall 37 b of the buffer member 37.

  In the example shown in FIG. 21, the side wall 38 a of the buffer member 38 is formed at a position corresponding to the bottom 2 b (body 2 a) of the container 2. A stopper 38c extends upward from the bottom wall 38b and is in contact with the bottom 2b (bottom surface 2b1) of the container 2. A first hollow portion 38e1 and a second hollow portion 38e2 are formed between the bottom 2b of the container 2 and the bottom wall 38b of the buffer member 38.

  In the example shown in FIG. 22, the side wall 39 a of the buffer member 39 is formed at a position corresponding to the bottom 2 b (body portion 2 a) of the container 2. Further, a flange portion 39f extends inward from the middle of the side wall 39a, and the stopper 39c extends further upward from the flange portion 39f. The stopper 39c is in contact with the bottom 2b (bottom surface 2b1) of the container 2. A first hollow portion 39e1 and a second hollow portion 39e2 are formed between the bottom 2b of the container 2 and the bottom wall 39b of the buffer member 39.

  Here, a continuous outer surface is formed on the body 2a and the side walls 33a to 39a of the container 2 by the buffer members 33 to 39 described above. By forming a continuous outer surface in this way, the heat-shrinkable film 5 can be adhered and covered with the outer surface of the container 2.

  In the embodiment described above, it is assumed that the buffer member 3 uses an elastically deformable resin, but the material is not particularly limited, and can be appropriately changed according to use. Further, not only resin but also paper or gel-like material may be used as long as it has impact resistance, and only a part such as the stopper 3c can be changed to another material.

  Moreover, in the Example shown above, although the part of the heat shrink film 5 is made into the printing area | region 6 on the surface of the heat shrink film 5, it is good also considering the whole surface of the heat shrink film 5 as the printing area | region 6. FIG. In addition, after attaching a display label on which information on the inside of the container is printed on the surface of the container 2 in advance, the heat shrinkage that is not printed on display instead of the heat-shrinkable film (heat-shrinkable label) 5 that is displayed and printed from above. You may make it wind a film. In this case, if the heat-shrinkable film is transparent, the display label attached to the container 2 below the heat-shrinkable film can be seen from the outside through the heat-shrinkable film. Moreover, although the case where the paste surface was formed in the back surface of the heat shrink film 5 was shown, the paste of a back surface is not necessarily required and you may use the heat shrink film without paste on the back surface. In this case, the heat-shrinkable film comes into close contact with or comes into contact with the surface of the container 2 or the buffer member 3 as the heat shrinks.

  Moreover, in the Example shown above, the position of the perforation 5a can be suitably changed according to a use application. For example, although the case where the perforation 5a is inserted horizontally with respect to the lid 4 is shown, the perforation 5a may be formed in the longitudinal direction with respect to the lid 4 and the perforation 5a is provided on the entire surface of the heat shrink film 5. The container 2 and the buffer member 3 may be separated at the time of disposal.

  As mentioned above, although embodiment of this invention was described, these are only illustrations to the last, and this invention is not limited to these, A various change is possible unless it deviates from the meaning of a claim. .
