Abstract

PROBLEM TO BE SOLVED: To provide a combination container having a paper support and a synthetic resin container main body, and the support is capable of exhibiting sufficient strength and heat insulation function.
A support body 10 is formed by folding a paper material. Both the first wall body 11 and the second wall body 12 have a double structure and have a hollow portion inside. Therefore, the strength of each of the walls 11 and 12 of the support 10 is high, and even if the container body 50 is filled with the contents, it is difficult to be deformed. Moreover, since the wall bodies 11 and 12 can exhibit a heat insulation function, even if the content in the container main body 50 is heated, it can suppress that the outer wall parts 11a and 12a of the wall bodies 11 and 12 become hot.

Description

  The present invention relates to a combination container in which a container body made of a synthetic resin material is installed in a recess of a support made of paper, and in particular, the strength of the support is high and the support has a heat insulating function. The present invention relates to a combination container that can be exhibited.

  As containers for storing food such as lunch boxes, confectionery, and side dishes in small portions, a combination container in which an exterior body is formed of a paper material and a container body made of a synthetic resin is held on the exterior body is widely used. This type of combination container accommodates food in a container body and performs color printing on the surface of a paper exterior body, thereby enabling display of colorful designs and trademarks.

In the conventional combination container of this type, a synthetic resin container body and a paper outer package are generally fixed with an adhesive. Or, as described in the following Patent Document 1 or the like, a hole is formed in a paper-made exterior body, a protruding portion protruding outward is formed in a synthetic resin container body, and the protruding portion and the hole The container which combined the container main body and the exterior body without using an adhesive agent by making this fit is also considered.
JP 2004-83091 A

  In any case, in the conventional combination container, since the exterior body is formed of a thin paper material, the exterior body does not have enough strength to reinforce the strength of the container body. Therefore, the container body has to be formed thick with a synthetic resin material to increase the strength. However, the container body formed thick with the synthetic resin material is heavier and the amount of discarded resin when it is discarded after use increases.

  Moreover, since the heat insulation function is weak in the paper-made exterior body, when the foodstuff in a container main body is heated with a microwave oven, an exterior body also becomes hot and it becomes difficult to hold | maintain by hand. Further, in the case where the container body and the exterior body are bonded and fixed with an adhesive such as a hot melt type, the container body and the exterior body bonded to the container body are deformed or contracted because the heated container body is deformed or contracted. Due to the thermal stress between them, the container is distorted and the contents are easily spilled.

  The present invention solves the above-described conventional problems, and an object thereof is to provide a combination container in which the strength of a support formed of paper can be increased and the support can also exert a heat insulating effect. .

  Furthermore, the present invention is a combination of a paper support and a synthetic resin container body, which can maintain high strength, and can easily assemble the support and the container with a concave-convex fitting. The object is to provide a combination container that can be separated and discarded separately.

The present invention has a support body having a recess surrounded by a wall body and a container body having a concave storage portion, and the combined container in which the storage portion is stored in the recess,
The support is formed of a paper material, the wall body has an outer wall portion and an inner wall portion, and a space is formed between the outer wall portion and the inner wall portion,
The container main body is formed of a synthetic resin material, and a fitting portion is provided between the support and the container main body to restrict separation of the storage portion in a state of being installed in the recess. It is characterized by being.

  In the combination container of the present invention, the support is made of paper, but the wall has an outer wall portion and an inner wall portion, and the space between the outer wall portion and the inner wall portion is a hollow portion. High strength. Therefore, the container body can be firmly supported by the wall body, and even when the container body tries to deform due to the weight of the contents, the deformation can be regulated. Moreover, since the wall body exhibits a heat insulating function, even when the contents of the container main body are heated, the support body can be prevented from being abnormally heated, and the support body can be easily grasped by hand.

  In addition, since the container body and the support are fitted in the fitting portion, there is no need to fix the container body and the support using an adhesive, and the container body and the support can be pressed against each other. Easy to assemble. Therefore, even if the container body is deformed by heat, no stress is generated between the container body and the support body, and the support body can be prevented from being distorted. In the present invention, it is preferable for the above reason that the container body and the support are not bonded to each other. However, the container body and the support may be bonded and fixed as necessary.

  In the present invention, for example, a hole surrounded by a cutting line is formed in at least one of the outer wall portion and the inner wall portion of the support body, and a protrusion is formed integrally with the container body, The fitting portion is constituted by the protrusion and the hole.

  In the present invention, it is preferable that the support is provided with a top portion that is bent at a right angle to both the outer wall portion and the inner wall portion and formed flat.

  In this case, at the wall portion of the support body, the outer wall portion is bent at a right angle from the bottom surface of the recess, and the inner wall is positioned at a position spaced inward from the bending boundary line between the bottom surface and the outer wall portion. The lower end part of the part can be configured as being fixed to the bottom surface.

  As described above, when the lower end portion of the inner wall portion is fixed at a position shifted inward on the bottom surface of the recess, the inner wall portion only has to be bent so that the outer wall portion and the inner wall portion are raised together. Walls can be easily formed.

  Further, according to the present invention, a pair of the wall bodies in which a lower end portion of the inner wall portion is fixed to the bottom surface is a first wall body, and a second wall body which is another pair of wall bodies is the bottom surface. The outer wall portion is bent at a right angle, the top portion is bent at a right angle at the upper end of the outer wall portion, the inner wall portion is bent at a right angle from the top portion, and the inner wall portion and the first wall portion of the second wall body are A protruding piece is formed on one of the inner wall portions of the wall body, and a cutout portion is formed on the other, and the protruding piece and the cutout portion are fitted to position the inner wall portion of the second wall body. It is possible to have a structure.

  In the above structure, the pair of first wall bodies are bent first, then the outer wall portion, the top portion, and the inner wall portion of the second wall body are bent, and the inner wall portion and the inner wall portion of the first wall body are projected. The second wall body can be easily bent and formed by fitting with the piece and the notch.

  In the present invention, it is preferable that the container main body has a flange portion around the opening of the storage portion, and the flange portion is installed on the top of the wall body. Moreover, the cover material sheet | seat shall be melt | fused by the surface of the said flange part, and the opening part of the said accommodating part shall be closed.

  Further, the present invention provides a force required to separate the container body and the support body, which are regulated by the fitting portion, from a force required to peel the lid sheet from the surface of the flange portion. It is preferable that it is larger.

  Thus, if the fitting force of a fitting part is strengthened, it can prevent that a container main body remove | deviates from a support body, when peeling the cover material sheet | seat melt | fused by the flange part of a container main body. Moreover, after use, the fitting at the fitting portion is forcibly released, so that the synthetic resin container main body and the paper support can be separated and discarded.

  The present invention can increase the strength of the wall of the support made of paper, and can firmly hold the synthetic resin container body with the support. Moreover, since the wall body of a support body exhibits the heat insulation function, even if the contents of a container main body are heated, it can prevent that a support body becomes abnormally hot.

  FIG. 1 is an exploded perspective view of a combination container according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view showing an internal structure of the combination container. FIG. 3 is a developed view of a paper material blank for bending the support, and FIGS. 4 and 5 are partial perspective views showing a process of forming the support by bending the paper blank.

  The combination container 1 shown in FIG. 1 has a support body 10 and a container body 50 supported by the support body 10.

  The support 10 shown in FIG. 1 is formed by cutting and bending a paper material (thick paper), and has a quadrangular planar shape. The support 10 includes a pair of first wall bodies 11 and 11 facing each other in the X direction, and a second wall body 12 facing each other in the Y direction in a direction orthogonal to the first wall bodies 11 and 11. 12. The support 10 has a recess 13 surrounded by four wall bodies, that is, a first wall body 11, 11 and a second wall body 12, 12. The recess 13 has a bottom surface 14 and is open upward.

  FIG. 2 is a cross-sectional view of the combination container 1 cut along a cutting plane parallel to the XZ plane. In the cross-sectional view of FIG. 2, the right side of the center line O shows a state where the container body 50 is not installed, and the left side of the center line O shows a state where the container body 50 is installed.

  The support 10 can be formed by adhering a plurality of independent paper materials to each other to form each part, but the support 10 of this embodiment is a single sheet developed as shown in FIG. It is formed by bending from a blank formed of a paper material.

  FIG. 2 shows a cross section of the pair of first wall bodies 11. Each of the first wall bodies 11 includes an outer wall portion 11a that is exposed to the outside, an inner wall portion 11c that is arranged at an interval inside the outer wall portion 11a, an upper end of the outer wall portion 11a, and an upper end of the inner wall portion 11c. And a top portion 11b connecting the two. The outer wall portion 11a is formed by being bent at a right angle from the bottom surface 14 of the recess 13 in the Z direction, and the outer wall portion 11a constitutes a flat wall surface parallel to the YZ plane. The bottom surface 14, the outer wall portion 11a, and the bending boundary line are indicated by L1. The top portion 11b is bent at a right angle at the portion of the bending boundary line L2 at the upper end of the outer wall portion 11a. The top portion 11 b is a flat surface parallel to the bottom surface 14.

  The inner wall portion 11c is bent at a right angle from the top portion 11b at the bending boundary line L3. Therefore, the inner wall portion 11c is a flat wall surface parallel to the outer wall portion 11a and parallel to the YZ plane. At the lower end of the inner wall portion 11c, an adhesive piece 11d that is bent at a right angle along a bending boundary line L4 is integrally provided. The adhesive piece 11d is bonded and fixed to the upper surface of the bottom surface 14 with glue. The adhesive piece 11d is bonded and fixed to the bottom surface 14 at a position further away from the outer wall portion 11a to the inside (center O side) of the recess 13. That is, in a state where the adhesive piece 11d is bonded and fixed to the bottom surface 14, the folding boundary line L4 is located farther inside the concave portion 13 than the bending boundary line L1.

  The distance between the folding boundary line L1 and the folding boundary line L4 in the X direction is substantially equal to the distance between the folding boundary line L2 and the folding boundary line L3 in the X direction. Therefore, the outer wall part 11a and the inner wall part 11c are parallel, and the cavity part 17 is formed between the outer wall part 11a and the inner wall part 11c.

  In the blank shown in FIG. 3, the same reference numerals as those in FIG. 2 are given to the respective portions of the paper material developed on the plane. Moreover, in FIG. 3, the bending boundary line is shown with the broken line. A portion indicated by a solid line in FIG. 3 is an outline line of the paper material or a cutting line obtained by cutting the paper material.

  In the blank shown in FIG. 3, a part of the trimmed paper material is folded back flat in advance at the folding boundary line L2, and the adhesive piece 11d and the bottom surface 14 are bonded and fixed in advance with glue.

  The folding direction of each folding boundary line is based on the blank shown in FIG. 3, and the portion that sandwiches the folding boundary line is folded toward the back side of FIG. 3 as a mountain fold, and the folding boundary line is sandwiched. Folding the part toward the front side of the page is a valley fold.

  FIG. 4 shows a state in which the first wall 11 is raised from the blank shown in FIG. In the blank of FIG. 3, this can be completed by a simple operation of folding the folding boundary line L1 and the folding boundary line L4 at a right angle by valley folding and folding the folding boundary line L3 at a right angle by mountain folding. As described above, since the adhesive piece 11d is bonded and fixed to the bottom surface 14 with glue in advance at the blank stage of FIG. 3, the outer wall portion 11a and the inner wall portion 11c are made parallel only by the bending operation shown in FIG. It is possible to start up.

  In the blank shown in FIG. 3, upper support pieces 11e separated by a cutting line C1 are provided at both ends in the Y direction of the inner wall portion 11c. Therefore, as shown in FIG. 4, when the first wall body 11 is raised, the upper support piece 11 e is parallel to the XY plane, that is, continuous with the same surface as the top portion 11 b and directed upward of the recess 13. It extends.

  In the blank shown in FIG. 3, bending boundary lines L11 are provided on both sides of the bottom surface 14 in the Y direction, and the outer wall portion 12a extends integrally outside the bending boundary line L11. A top portion 12b is positioned outside the outer wall portion 12a via a bending boundary line L12, and an inner wall portion 12c extends outside the top portion 12b with the bending boundary line L13 interposed therebetween. Further, a bottom support piece 12d is integrally provided on the inner wall portion 12c via a bending boundary line L14.

  In addition, a concave cutting line C2 is cut in the middle of the bending boundary line L14 toward the bottom surface 14, and is continuous with the bottom support piece 12d in the part surrounded by the cutting line C2. A supporting tongue 12e is provided.

  Further, a corner piece 15 is integrally provided at a boundary portion between the outer wall portion 11 a of the first wall body 11 and the outer wall portion 12 a forming the second wall body 12. A bending boundary line L21 extending obliquely toward the intersection of the bending boundary line L1 and the bending boundary line L11 is provided.

  FIG. 5 shows a process of forming the second wall bodies 12 by folding the blank.

  As shown in FIG. 4, after each of the pair of first wall bodies 11, 11 is bent at a right angle from the bottom surface 14, the paper material is bent at a right angle so as to be a valley fold at a bending boundary line L <b> 11, The outer wall 12a of the second wall 12 is raised vertically. At this time, the folding boundary line L21 of the corner piece 15 is folded back into a mountain fold, and the folded corner piece 15 is overlapped on the inner surface of the outer wall portion 12a.

  After the outer wall portion 12a rises vertically, the top portion 12b is bent so as to be a flat surface parallel to the bottom surface 14 by bending at a folding boundary line L12 at a right angle to the valley folding direction. Next, the inner wall portion 12c is formed by bending the folding boundary line L13 at a right angle in the valley folding direction. At this time, the upper support piece 11e continuous with the top portion 11b of the first wall body 11 hits the lower surface of the top portion 12b of the second wall body 12, and the upper support piece 11e is sandwiched between the outer wall portion 12a and the inner wall portion 12c. It is.

  As shown in FIG. 5, when the outer wall portion 12a of the second wall body 12 is raised from the bottom surface 14, and the top portion 12b and the inner wall portion 12c are further bent, both sides of the inner wall portion 12c of the second wall body 12 are obtained. The protruding pieces 12g that integrally protrude from the sides are fitted into the notches 11g that are formed in a concave shape on both lower sides of the inner wall 11c of the first wall 11. Thereby, it can control that inner wall part 12c lifts in the direction away from bottom 14, and it can control that inner wall part 12c changes in the direction away from outer wall part 12a.

  As shown in FIG. 5, when the bottom support piece 12d is bent at a right angle at the lower end of the inner wall portion 12c when the inner wall portion 12c is bent, the protruding piece 12g is fitted into the notch portion 11g. The bottom support piece 12d and the support tongue 12e that is continuous with the bottom support piece 12d are almost in close contact with the upper surface of the bottom surface 14. At this time, the tip of the support tongue 12e hits the inner surface of the outer wall portion 12a, and the support tongue 12e allows the inner wall portion 12c to maintain a distance from the outer wall portion 12a.

  Due to the fitting of the protruding piece 12g and the notch 11g and the spacer function of the support tongue 12e, both the outer wall 12a and the inner wall 12c rise vertically from the bottom surface 14, and the outer wall 12a and the inner wall 12c are mutually connected. Become parallel. Moreover, as shown in FIG. 5, the cavity part 16 is formed between the outer wall part 12a and the inner wall part 12c.

  In this way, in the blank of FIG. 3, if the adhesive piece 11 d continuous with the inner wall portion 11 c of the first wall body 11 is adhered to the bottom surface 14, then, as shown in FIG. 4, the first wall The body 11, 11 is bent so as to stand up vertically, and further, as shown in FIG. 5, by folding each part constituting the second wall body 12, a rectangular frame shape can be obtained without going through an adhesion process. The support 10 can be completed. In this embodiment, the support 10 shown in FIG. 1 can be easily completed from the blank shown in FIG. In addition, you may adhere | attach the said bottom part support piece 12d which comprises the 2nd wall body 12 to the bottom face 14 as needed.

  The container body 50 is formed of a synthetic resin material. The container body 50 has a three-dimensional shape in the process of heating and softening a thermoplastic synthetic resin sheet such as PP (polypropylene) or PET (polyethylene terephthalate), and adsorbing or pressurizing the inner surface of the concave mold. It is molded into

  As described above, the first wall 11 and the second wall 12 of the support 10 have a double structure, and the support 10 has a very high support strength. Therefore, even if the container body 50 is formed of a thin synthetic resin sheet and has relatively low rigidity, the container body 50 can be firmly held by the support 10. Therefore, when the container body 50 is filled with the contents, even the relatively thin container body 50 is not easily deformed.

  The container body 50 includes a storage part 51 that is concave and has an opening on the top, and a flange part 52 that projects from the opening of the storage part 51 in both the X direction and the Y direction. The flange portion 52 is a flat surface parallel to the XY plane, and a small bending piece 53 that extends downward with a narrow width is provided on the outer peripheral portion thereof.

  As shown in FIG. 2, when the storage portion 51 of the container main body 50 is installed in the recess 13 of the support body 10, the flange portion 52 becomes the top portions 11 b and 11 b of the first wall bodies 11 and 11 of the support body 10. The small bent piece 53 is hooked on the outer surfaces of the outer wall portions 11a, 11a, 12a, and 12a, in contact with the top portions 12b and 12b of the second wall bodies 12 and 12. At the same time, the bottom surface 54 of the storage portion 51 hits the bottom surface 14 of the concave portion 13 of the support 10.

  Between the support body 10 and the container main body 50, the uneven | corrugated fitting part 20 which controls so that both may not isolate | separate easily in the assembly state shown in FIG. 2 is provided. In the concave / convex fitting portion 20, a hole is provided in one of the support 10 and the container main body 50, and a protrusion is provided on the other.

  In the embodiment shown in FIGS. 1 to 5, holes 21 are formed in the inner wall portions 11 c and 11 c of the first wall body 11 and the inner wall portions 12 c and 12 c of the second wall body 12. The hole portion 21 is formed by separating the paper material forming the respective inner wall portions 11c and 12c by a cutting line C5. The cutting line C5 is formed in a U shape having a horizontal line extending parallel to the XY plane and a vertical line extending from both sides of the line to the bottom surface 14. The portion cut by the horizontal line is the upper edge portion 21 a of the hole portion 21. Also, in the hole portion 21, a rectangular tongue piece formed of a paper material constituting the inner wall portion 11c or a paper material constituting the inner wall portion 12c extends upward.

  On the upper outer surface of the storage portion 51 of the container main body 50, a protruding portion 22 that protrudes outward is provided. As shown in FIG. 2, the upper end 22 a of the protrusion 22 is a flat surface that protrudes substantially parallel to the bottom surface 14 of the support 10, and the lower portion thereof is directed toward the bottom surface 14 and the bottom surface 54. Therefore, the inclined surface 22b is inclined to the center line O. The inclined surface 22b here is an inclined plane or an inclined protruding surface.

  As shown in FIG. 2, the storage portion 51 of the container body 50 is stored in the recess 13 of the support body 10, and the bottom surface 54 of the container body 50 hits the bottom surface 14 of the support body 10, or the flange portion of the container body 50. When 52 hits the top portions 11b and 12b of the first wall body 11 and the second wall body 12, the protrusions 22 provided on the container body 50 are holes formed in the inner wall portions 11c and 12c, respectively. Get into the part 21. At this time, as shown in FIG. 2, the tongue of the paper material positioned in the hole 21 is pushed by the protrusion 22 and deformed toward the inside of the cavities 16 and 17.

  The protrusion 22 is formed with a flat upper end 22a, and the hole 21 is provided with a horizontal upper edge 21a. Since the upper edge 22a and the upper edge 21a face each other, all protrusions The container body 50 is regulated by the concave / convex fitting portion 20 so that the container main body 50 does not easily escape upward from the support body 10 in a state where the portion 22 has entered all the holes 21.

  In particular, the protrusion dimension δ of the protrusion 22 into the hole portion 21 shown in FIG. 2 is larger than the thickness dimension of the paper material constituting the support 10, preferably more than three times the thickness dimension of the paper material. By setting, the container body 50 cannot be separated from the support body 10 unless the support body 10 is destroyed in a state where the container body 50 is installed on the support body 10.

  However, even after the projecting portion 22 and the hole portion 21 are fitted by making the upper end portion 22a of the projecting portion 22 into an inclined surface shape or a curved surface shape, or by reducing the entering dimension δ, The container body 50 can be configured to be relatively easily separable from the support 10 by pulling the container body 50 upward slightly.

  Further, when the fitting strength between the protrusion 22 and the hole 21 is increased as described above and the container body 50 and the support 10 are difficult to separate, as shown in FIG. It is preferable to provide a separation portion 25 that can cut and peel the paper material at the perforated portion at least a part of the outer wall portion 11a of the first wall body 11 and the outer wall portion 12a of the second wall body. After using the combination container 1, the separating member 25 separates the paper material in at least a part of the outer wall parts 11 a and 12 a, inserts a finger from the part, pushes the protruding part 22 by hand, and removes it from the hole part 21. By letting out, the container body 50 made of synthetic resin and the support 10 made of paper can be discarded separately.

  In this combination container 1, the support body 10 is made of paper (made of cardboard), but the first wall bodies 11 and 11 and the second wall bodies 12 and 12 are made up of outer wall portions 11a and 12a and inner wall portions 11c and 12c. Since it has a double structure, the strength is high, and particularly the strength against the pressure acting on the top portions 11b and 12b from above is high. Therefore, the container main body 50 can be firmly held, and even if the container main body 50 is formed from a relatively thin resin sheet and the storage unit 51 is filled with contents such as food, the storage unit 51 is not easily deformed.

  Moreover, since the 1st wall body 11 has the cavity part 17 inside, and the 2nd wall body 12 also has the cavity part 16 inside, each wall body 11 and 12 has sufficient heat insulation function. Can demonstrate. When the contents stored in the container body 50 are heated by a microwave oven or the like, the heat of the contents is not easily transmitted to the outer wall portion 11a of the first wall body 11 and the outer wall portion 12a of the second wall body 12. The outer wall portions 11a and 12a can be easily held by hand.

  Furthermore, since it is not necessary to fix the container main body 50 and the support 10 with an adhesive, even if the container main body 50 is deformed by the heat of the contents, thermal stress acts between the container main body 50 and the support 10. There is nothing to do. Moreover, the container main body 50 to be deformed is not restrained by the support body 10, and the container main body 50 can be prevented from being abnormally distorted.

  FIG. 6 shows an embodiment in which the opening above the container body 50 is sealed with the lid sheet 30. The lid material sheet 30 is a PET sheet or a PP sheet, and a surface facing the container body 50 is provided with a sealant layer such as low density polyethylene. The inside of the storage part 51 of the container main body 50 can be sealed by fusing the lid sheet 30 to the surface of the flange part 52 of the container main body 50 through the sealant layer by heat sealing or ultrasonic sealing.

  As shown in FIG. 2, by making the upper end portion 22a of the protrusion 22 constituting the concave-convex fitting portion 20 a flat surface and sufficiently increasing the intrusion dimension δ at which the protrusion 22 intervenes in the hole portion 21, It becomes difficult for the container main body 50 to escape from the support 10 upward. Therefore, the force required to separate the container body 50 upward from the support 10 is larger than the force required to peel the lid sheet 30 shown in FIG. 6 from the surface of the flange portion 52 of the container body 50. Is possible. In this case, the lid seal 30 that closes the opening of the container body 50 can be peeled off while the container body 50 is supported by the support 10. Therefore, the lid member sheet 30 can be peeled off while the container main body 50 storing the heated contents is held by the heat insulating support 10, which is easy to use.

  And after use, the container main body 50 and the support body 10 can be separated and discarded by partially breaking the paper support body 10 or by separating the separation part 25 shown in FIG. .

  Moreover, the 1st wall body 11 and the 2nd wall body 12 of the support body 10 can exhibit high intensity | strength with respect to the pressure from upper direction with a double structure. Therefore, as shown in FIG. 6, the support 10 and the container main body 50 are installed on the transport unit 31 having a flat surface, and the lid member sheet 30 and the flange portion 52 of the container main body 50 are directly attached by the seal head 32 from above. By pressing and heating, the lid material sheet 30 can be fused to the flange portion 52 of the container main body 50.

  That is, as a manufacturing method of the combination container 1, after supplying the contents into the storage portion 51 of the container body 50 supported by the support 10, without individually supporting the flange portion 52 of the container body 50 with a jig or the like, The container body 50 can be sealed with the lid seal 30 in a state where the flange portion 52 is supported by the first wall body 11 and the second wall body 12 of the support body 10.

  Alternatively, in this embodiment, the container main body 50 in a state separated from the support 10 is filled with the contents, and the container main body 50 is sealed with the lid sheet 30, and then the container main body 50 is attached to the support 10. The combination container 1 can be manufactured by a simple operation of pushing from above.

  Alternatively, as shown in FIG. 7, a lid 35 molded in a three-dimensional shape with a thermoplastic resin sheet in the same manner as the container body 50 is used, and the fitting portion 35 a on the outer periphery of the lid body 35 is connected to the container body 50. The housing portion 51 of the container body 50 may be sealed by being mechanically fitted to the flange portion 52.

  Also in this case, the force required to separate the container main body 50 upward from the support 10 is made larger than the force required to remove the lid 35 from the flange portion 52 of the container main body 50. The lid 35 can be removed from the opening of the container body 50 while the container body 50 is supported by the support 10.

  The combination container of the present invention can be variously modified in addition to the above embodiment. 8 to 11 show modifications of the combination container of the present invention.
