Description

  The present invention relates to a container for viscous liquid, and more particularly to a container for squeezing viscous liquid.

  Conventionally, flexible tube containers formed by blow molding or the like have been used as food containers for storing viscous liquids such as mayonnaise. In such a tube container, when the internal volume of the contents is reduced, the main body of the tube container is crushed and the container is bent at the crushed portion, so that it is difficult to make the tube container itself self-supporting. Thus, when a tube container cannot be made self-supporting, the space at the time of storing a tube container becomes large, and will occupy limited storage space, such as a refrigerator, more than necessary. Further, if air is introduced into the tube container in order to make the tube container self-supporting, there is a possibility that the contents are deteriorated due to oxidation or the like. In order to solve such a problem, it is possible to pour out the contents filled in the inner container by applying a squeeze pressure to the outer container using a double structure container composed of the outer container and the inner container. It has been proposed (see, for example, Patent Document 1). According to this technique, it is possible to ensure the self-supporting property of the container and prevent the contents from being oxidized.

JP 2012-250732 A

  However, the double structure container as proposed in Patent Document 1 has a more complicated structure than the conventional tube container. Therefore, the manufacture of the double structure container is more difficult than the tube container.

  The present invention has been made to solve the above-described conventional problems, and is a viscous liquid that is easy to manufacture and that can suppress the deterioration of the contents due to oxidation or the like while ensuring the self-supporting property of the container. The purpose is to provide a container.

  In order to achieve at least a part of the above object, the present invention can be realized as the following forms or application examples.

[Application Example 1]
A viscous liquid container configured to contain a viscous liquid and squeeze out the viscous liquid, the mouth formed in a substantially cylindrical shape around the container axis, and formed in a substantially flat plate shape, A viscous liquid comprising: a bottom portion disposed perpendicular to a container axis; and a body portion disposed between the mouth portion and the bottom portion and connected to each of the mouth portion and the bottom portion. The container is formed with a plurality of bendable portions that facilitate bending inward or outward of the viscous liquid container in at least a part of the body portion connected to the bottom portion. As the viscous liquid is squeezed out, the bottom moves toward the bottom advancing surface located on the mouth side from the bottom while maintaining the state orthogonal to the container axis, and the at least part In the region from the bottom advancing surface to the mouth Bought recess extending is configured to be formed, viscous liquid container.

  According to this application example, when the viscous liquid is squeezed out and the internal volume decreases, at least a part of the body portion of the viscous liquid container connected to the bottom portion is directed from the bottom advancement surface toward the mouth portion. An extending recess is formed. By forming the concave portion, the partial region is prevented from being bent, so that the self-supporting property of the viscous liquid container is ensured even when the internal volume is reduced. Moreover, since the self-supporting property can be ensured without putting air into the viscous liquid container, deterioration of the viscous liquid accommodated in the viscous liquid container such as oxidation can be suppressed.

[Application Example 2]

A viscous liquid container in which a direction curve portion is formed.

  According to the application example 2, by forming the longitudinally inwardly easy curved part and the longitudinally outwardly easily curved part sandwiching the longitudinally inwardly easily curved part in the large diameter part, the bottom advancement surface is changed to the mouth part. It is possible to promote the formation of a recess extending toward the front. Therefore, as the viscous liquid is squeezed out, it is possible to more easily realize a viscous liquid container in which a concave portion extending from the bottom advance surface toward the mouth is formed in the large diameter portion.

[Application Example 3]
In the viscous liquid container according to Application Example 2, a bottom outwardly bendable portion is formed at a connection portion between the bottom portion and the large diameter portion, and the large diameter portion includes an inner portion in the longitudinal direction. A viscous liquid container in which an inwardly easy-to-curve portion extending from the end of the easy-to-curve portion on the bottom advancing surface side to the intersection of the longitudinally outwardly easily curved portion and the bottom outwardly easily curved portion is formed. .

  According to the application example 3, the bottom outer easily curved portion formed in the connecting portion between the bottom portion and the large diameter portion, and the large diameter portion formed from the end on the bottom forward surface side of the longitudinally inner easily curved portion. When the viscous liquid is squeezed out by the inwardly easy-to-extend portion extending to the intersection of the longitudinally outwardly-flexible portion and the bottom-side outwardly-flexible portion, the bottom portion is more reliably moved toward the bottom advancement surface. be able to. Therefore, it is possible to more easily realize a viscous liquid container in which the bottom portion moves toward the bottom advance surface as the viscous liquid is squeezed out.

[Application Example 4]
4. The viscous liquid container according to any one of application examples 1 to 3, wherein an end portion of the easy-curving portion is formed in a partial spherical shape.

  By making the end part of the easy-to-be-curved part into a partial spherical shape, it is possible to suppress breakage of the tip of the easily-curing part and to make the easily-curing part easier to bend.

[Application Example 5]

The container forms a plurality of urging portions that are urged so as to bend inward or outward of the viscous liquid container in at least a part of the body portion connected to the bottom portion. As the viscous liquid is squeezed out from the filled state filled with the viscous liquid, the mouth side is more than the bottom portion in the filled state while maintaining the state where the bottom portion is orthogonal to the container axis. And move to the bottom advancing surface side At least in some regions a recess extending toward the opening from the bottom forward surface is configured to be formed, viscous liquid container.

  According to this application example, when the viscous liquid is squeezed out and the internal volume decreases, at least a part of the body portion of the viscous liquid container connected to the bottom portion is directed from the bottom advancement surface toward the mouth portion. An extending recess is formed. By forming the concave portion again, the partial region is prevented from being bent, so that the self-supporting property of the viscous liquid container is ensured even when the internal volume is reduced. Moreover, since the self-supporting property can be ensured without putting air into the viscous liquid container, deterioration of the viscous liquid accommodated in the viscous liquid container such as oxidation can be suppressed.

A. First embodiment:
A1. Container outline:
FIG. 1 is a schematic perspective view showing a schematic shape of a container 100 in the first embodiment of the present invention. The container 100 has a mouth part 110, a body part 120, and a bottom part 130. The mouth part 110, the body part 120, and the bottom part 130 are formed in this order along the container axis indicated by the alternate long and short dash line. The mouth portion 110 is formed in a substantially cylindrical shape with the container axis as the center, and has an opening portion 112 through which a viscous liquid is discharged, and a screw portion 114 that is fitted to a lid (not shown). In an actual usage pattern of the container 100, a film-like member provided with a hole smaller than the inner diameter of the opening 112 is fused to the opening 112 in order to limit the discharge amount of the viscous liquid. However, the illustration thereof is omitted here. Note that the mouth portion 110 and its configuration are not directly related to the present invention, and thus detailed description thereof is omitted.

  The body 120 is connected to the mouth 110 having a small outer diameter, and is formed between the neck 122 and the neck 122 and the bottom 130 formed so that the outer diameter increases as the distance from the mouth 110 increases. And a large-diameter portion 124 whose outer diameter is sufficiently larger than the mouth portion 110 (for example, the cross-sectional area is twice or more). The trunk portion 120 is flexible so that the viscous liquid can be squeezed out from the mouth portion 110. Thus, the container 100 in which the trunk | drum 120 has flexibility is integrally formed by blow-molding the resin film which has flexibility and oxygen barrier property, for example. As the resin film to be blow-molded, it is preferable to use a multilayer film in which an ethylene-vinyl alcohol copolymer is sandwiched between polyethylene or nylon, but it is not always necessary to use a multilayer film.

  The bottom part 130 is formed in a substantially flat plate shape and is arranged so as to be orthogonal to the container axis. The edge of the bottom portion 130 is connected to the end of the trunk portion 120. By connecting the bottom portion 130 and the trunk portion 120 in this manner, a lid (not shown) attached to the mouth portion 110, the mouth portion 110, the trunk portion 120, and the bottom portion 130 form a sealed space. And viscous liquid is accommodated in the formed sealed space.

  The viscous liquid is mainly contained in a space surrounded by the trunk 120 and the bottom 130. As shown in FIG. 1, the container 100 of the first embodiment has a larger diameter portion 124 because the trunk portion 120 has a larger diameter portion 124, so that more viscous liquid can be obtained than when the large diameter portion 124 is not provided. Can be accommodated. Although illustration is omitted in FIG. 1 for convenience, in the container 100 of the first embodiment, the large diameter portion 124 and the connection portion between the large diameter portion 124 and the bottom portion 130 are connected to the outside of the container 100. An easy-to-bend portion that facilitates inward and inward bending is provided. The specific configuration and effect of this easy-to-play part will be described later.

A2. Easy composition:
2 and 3 are explanatory views showing the arrangement of the easy-to-bend parts in the container 100 of the first embodiment. FIG. 2A shows a state where the container 100 is viewed from the surface (front) where the large-diameter portion 124 looks wide, and FIG. 2B shows the surface where the width of the large-diameter portion 124 appears narrow. It shows how it was seen from (side). FIG. 3A shows a state where the container 100 is viewed from the bottom, and FIG. 3B shows a cross-sectional end of the container 100 at the cut surface A (see FIG. 2). 2 and FIG. 3, the broken line indicates the outer shape of the portion where the bendable portion is not formed in the container 100.

  2 (a), FIG. 2 (b) and FIG. 3 (a) and the black circle in FIG. 3 (b) are the outward bending of the container 100, that is, the mountain viewed from the outer surface of the container 100. The easy-to-fold easy-to-fold parts (outside easy-to-turn parts) 221, 225, 231, 232 are shown. 2 (a), FIG. 2 (b) and FIG. 3 (a) and the white circle in FIG. 3 (b) are bent inward of the container 100, that is, viewed from the outer surface of the container 100. The easy music parts (inward music parts) 222, 223, and 224 that can be easily folded are shown. In the present specification, a direction that becomes convex by bending as described above is defined as a bending direction (bending direction).

  As shown in FIG. 2 and FIG. 3, in the large-diameter portion 124, an inward bending portion 222 is formed at an end in a wide direction (hereinafter referred to as “lateral direction”), and the inward bending portion 222. An outwardly easy-to-curve portion 221 is formed so as to sandwich the. The outward easy bending portion 221 is an outward easy bending portion 231 formed on the edge of the bottom portion 130 (that is, a connection portion between the large diameter portion 124 and the bottom portion 130) from the end of the large diameter portion 124 on the neck portion 122 side. , 232 is reached. On the other hand, the inwardly easy-to-curve portion 222 faces the bottom portion 130 from the end on the neck portion 122 side of the large-diameter portion 124 and stops before the bottom portion 130.

  In addition to the outer easily bent portion 221 and the inner easily bent portion 222, the large diameter portion 124 is adjacent to the outer portion adjacent to the bottom portion 130 from the end on the bottom 130 side of the inner easily bent portion 222. An outward easy music portion 225 extending to both sides of the easy music portion 221 is formed. At the extended end of the outward easy-to-curve portion 225, two outward easy-to-curve portions 225 formed on both side surfaces are connected, and an inward easy-to-curve portion 224 that is substantially parallel to the bottom portion 130 is formed. The large-diameter portion 124 also has an inwardly easy-to-curve portion 223 extending from the end on the bottom 130 side of the inwardly easy-to-curve portion 222 to the two outer easily-curved portions 231 and 232 at the edge of the bottom portion 130. Is formed.

  As shown in FIG. 2, the inner easily bent portion 224 and the outer easily bent portion 225 formed substantially parallel to the bottom portion 130 in the large-diameter portion 124 are planes having these easily bent portions 224 and 225 as outer edges. form. Similar to the bottom portion 130, this plane is orthogonal to the container axis (the chain line in FIG. 1). Then, as will be described later, in the container 100, when the contained viscous liquid is squeezed out and the internal volume decreases, the bottom portion 130 moves (advances) to a position near a plane having the bendable portions 224 and 225 as outer edges. To do. For this reason, the plane having the easy-to-curve portions 224 and 225 as outer edges is also referred to as a bottom forward surface. The inwardly easy-to-curve portion 222 extends from the bottom advance surface to the end on the neck 122 side near the mouth portion 110. Further, the outward easy-to-curve portion 221 extends from the bottom portion 130 to an end on the neck portion 122 side that is close to the mouth portion 110, intersecting the bottom portion advancement surface.

  FIG. 4 is a cross-sectional end view of the container 100 in a plane orthogonal to the easily bendable portion. FIG. 4A shows the shape of the bendable part BDF formed in the substantially flat surface region QFP. In FIG. 4A, for convenience of illustration, the surface region QFP is drawn as a flat plate. The bendable part BDF corresponds to the bendable parts 221 to 225 formed in the large diameter part 124 in FIGS. 2 and 3. In the example of FIG. 4A, the bendable part BDF protrudes from the surface region QFP in the bending direction and is formed in a semicircular shape having the same thickness as the surface region QFP.

  FIG. 4B shows the shape of the easy-bend portion BDI formed between two intersecting surface areas IPA and IPB. In FIG. 4B, for convenience of illustration, the two surface areas IPA and IPB are depicted as two orthogonal flat plates. The easily bendable part BDI corresponds to the outward easily bendable parts 231 and 232 formed between the large diameter part 124 and the bottom part 130 in FIGS. As shown in FIG. 4 (b), the bendable part BDI protrudes in the bending direction from the intersection of the two surface areas IPA and IPB, and is formed in a 3/4 circular shape with the same thickness as the surface areas IPA and IPB. ing. Here, the 3/4 circular shape is a shape obtained by removing a quadrant from a circle. In FIG. 4B, since the two surface areas IPA and IPB are drawn as two flat plates orthogonal to each other, the bendable portion BDI is formed in a 3/4 circular shape. , IPB are not orthogonal, the easy-to-bend portion BDI is formed in a shape in which a region corresponding to the intersection angle of the surface regions IPA, IPB is removed from the circle.

  In FIG. 4, the bendable parts BDF and BDI are substantially the same in thickness as the surface areas QFP, IPA and IPB near the bendable part and have a shape obtained by cutting a circle. The shape can be variously changed such as a so-called V-shape or U-shape. Generally, the bendable part has a thickness that is equal to or less than the thickness of the surface area near the bendable part, and may have a shape protruding in the bending direction. By forming such a bendable part, the surface area near the bendable part is easily bent in the direction opposite to the bending direction, and the bendable part is easily bent so that the bending direction is convex. .

  FIG. 5 is an explanatory diagram showing the shape of the end portion of the bendable portion BDF formed in the substantially flat surface region QFP. FIG. 5A shows a state where the end portion of the bendable portion BDF is viewed from the bending direction, and FIG. 5B shows the end of the bendable portion BDF in the cross section shown by the one-dot chain line in FIG. The cross-sectional end of the part is shown. In the example of FIG. 5, the tip of the bendable portion BDF has an outer diameter that is substantially the same as the width of the bendable portion BDF in the bending direction, and has a thickness that is substantially the same as the bendable portion BDF and the surface region QFP. Is formed.

  FIG. 6 is an explanatory view showing another shape of the end portion of the easy-to-be-curved part. 6A shows a state in which the end portion of the bendable portion BDF is viewed from the bending direction, and FIG. 6B is an end view of the bendable portion BDF in the cross section indicated by the one-dot chain line in FIG. The cross-sectional end of the part is shown. In the example of FIG. 6, the tip of the bendable part BDF is formed in a substantially hemispherical shape having an outer diameter larger than the width of the bendable part BDF in the bending direction and a thickness that is substantially the same as the bendable part BDF and the surface region QFP. Has been. As described above, when the outer diameter of the tip of the bendable part BDF is increased, the radius of curvature at the end of the bendable part BDF is increased. Thereby, the load added between the front-end | tip of the easily-curved part BDF and the surface area | region QFP disperse | distributes. Therefore, breakage of the tip of the easy-to-be-curved part BDF is suppressed, and the easily-curing part BDF is more easily bent.

  In the example of FIGS. 5 and 6, the end of the bendable part is a partial sphere that is a part of a sphere, but the end of the bendable part is not necessarily a partial sphere. For example, the height of the protruding portion that forms the bent portion may be abruptly reduced to 0 at the end of the bendable portion, or the height of the protruding portion may be asymptotically reduced to 0. However, as described above, it is preferable that the end portion of the easy-to-be-curved portion has a partial spherical shape in order to suppress breakage of the tip of the easily-curing portion and make the easily-curing portion easier to bend.

A3. Effect of easy music formation:
FIG. 7 is an explanatory diagram showing a state in which the contained viscous liquid is squeezed out and the internal volume is reduced in the container 100 of the first embodiment. Although not shown in the figure, the container 100 is formed with easy-to-tune parts 221 to 232 as shown in FIGS. Therefore, when the viscous liquid is squeezed out of the container 100, the inward easy-to-curve portion 222 formed at the lateral end is bent inward and the outward easy-to-out shape formed so as to sandwich the inward easy-to-turn portion 222. The curved portion 221 is bent outward. Therefore, the side surface of the large diameter portion 124 is folded inward of the container 100.

  As described above, the side surface of the large diameter portion 124 is folded inward of the container 100, the inwardly bending portions 223 and 225 of the large diameter portion 124 are bent inward, and the outward bent portion of the large diameter portion 124 is 224 and outwardly bendable portions 231 and 232 at the edge of the bottom portion 130 are bent outward. Thereby, the bottom part 130 moves toward the opening part 110 and a bottom part advance surface, maintaining the state orthogonal to the container axis shown with a dashed-dotted line.

  When the internal volume decreases as the contained viscous liquid is squeezed out, the side surface of the large-diameter portion 124 is folded, so that the large-diameter portion 124 has a narrow width (vertical direction) as shown in FIG. It will be crushed. At this time, a recess 190 is formed in the lateral direction of the large-diameter portion 124 by folding the lateral region. Since this recessed part 190 is formed so that it may go to a mouth part from a bottom part advance surface, it suppresses that the large diameter part 124 bends in the vertical direction. In general, the neck portion 122 is thicker than the large-diameter portion 124, so that it is naturally difficult to bend. Therefore, the container 100 squeezed out of the viscous liquid is erected so that the container axis indicated by the alternate long and short dash line is in the vertical direction while the viscous liquid is filled in the body 120 including the large diameter portion 124. It becomes easy to put it in a state (make it independent). Thereby, in order to make the container 100 which squeezed viscous liquid self-supported, it becomes unnecessary to introduce | transduce air into the container 100. FIG.

  Further, as shown in FIG. 7, in the container 100 of the first embodiment, the bottom portion 130 is kept in a state orthogonal to the container axis by folding the side surface of the large diameter portion 124. Therefore, it becomes easier to erect the container 100 with the bottom portion 130 down. Since the bottom part 130 generally has a larger outer diameter than a lid (not shown) attached to the mouth part 110, the container 100 can be made to stand more stably than when the mouth part 110 is turned upside down. Become. In addition, since both the lid and the bottom portion 130 are located on the container axis, the container 100 can be stably supported even when it is inverted.

  Thus, in the container 100 of the first embodiment, the container 100 can be made independent without introducing air into the container 100 even when the viscous liquid is squeezed out and the internal volume is reduced. The container 100 can be made self-supporting so that the storage property of the container 100 is improved while suppressing deterioration due to oxidation or the like of the viscous liquid stored in the container 100. Further, since the container 100 can be manufactured by a simple process such as blow molding, the container 100 can be easily manufactured.

B. Second embodiment:
FIG. 8 is a schematic perspective view showing a schematic shape of the container 100a in the second embodiment of the present invention. FIG. 8A shows the shape of an empty container 100a at the time of manufacture, and FIG. 8B shows the shape of the container 100a in a state where the container 100a is filled with a viscous liquid. As shown in FIG. 8A, the container 100a of the second embodiment is the same as the container 100a of the first embodiment in that the side surface of the large diameter portion 124 is folded inward. Different from the container 100. In addition, the container 100a of the second embodiment can be formed by blow molding similarly to the container 100 of the first embodiment.

  When the container 100a shown in FIG. 8A is manufactured, that is, when the container 100a is empty, the container 100a is located at the position corresponding to the inwardly bent portions 222, 223, and 224 in FIGS. It is urged to bend in the direction. Further, the container 100a is urged so as to be bent outward at positions corresponding to the outwardly easy-to-bend portions 221, 225, 231, 232. Accordingly, on the edges of the large-diameter portion 124a and the bottom portion 130a of the container 100a of the second embodiment, the inner easily bent portions 222, 223, 224 and the outer easily bent portions 221, 225, It can be said that an inner urging portion and an outer urging portion corresponding to each of 231 and 232 are formed. By forming the inner urging portion and the outer urging portion, the container 100a is formed with a recess 190a that facilitates the self-supporting of the container 100a. In the urging portion, the container 100a itself in which the urging portion is formed is urged so as to bend inward or outward. Therefore, it can be said that the urging portion itself is urged so as to bend inward or outward.

  When the empty container 100a shown in FIG. 8A is filled with the viscous liquid, the bent inner biasing portion and the outer biasing portion are opposite to the biasing direction due to the pressure of the filled viscous liquid. Expand to. As a result, as shown in FIG. 8B, the large-diameter portion 124a of the container 100a filled with the viscous liquid spreads, and the container 100a contains a lot of viscous liquid in the same manner as the container 100 of the first embodiment. It becomes possible to do.

  As shown in FIG. 8B, after the viscous liquid stored in the container 100a is squeezed out after the container 100a is filled with the viscous liquid, the inner urging portion and the outer urging portion are moved in the urging direction. The concave portion 190a is formed again by bending. When the viscous liquid is further squeezed out, the large-diameter portion 124a is crushed in the vertical direction by the atmospheric pressure applied from the outside of the container 100a, as in the case of the container 100 of the first embodiment (see FIG. 7). Therefore, in the container 100a of the second embodiment, it is possible to make the container 100a self-supporting without introducing air into the container 100 in a state where the viscous liquid is squeezed out and the internal volume is reduced. The container 100a can be made self-supporting so that the storage property of the container 100a is enhanced while suppressing deterioration due to oxidation or the like of the stored viscous liquid.

C. Modified example of arrangement of easy-to-tune parts:
FIG. 9 is an explanatory view showing a modified example of the arrangement mode of the easy-to-play parts. In FIG. 9, for convenience of illustration, only the large diameter portion 124b and the bottom portion 130b are shown, and the bulges between the large diameter portion 124b itself and the edge of the bottom portion 130b are omitted. 9 (a) to 9 (c) show a state in which the large-diameter portion 124b is viewed from the front, a state in which the large-diameter portion 124b is viewed from the side, and a state in which the bottom 130b is viewed from the bottom. ing. Similarly to FIGS. 2 and 3, also in FIG. 9, the alternate long and short dashed lines indicate the outward easy curved portions 321, 325, 331, and 332, and the alternate long and two short dashes lines indicate the inward easy curved portions 322, 323, and 324 , 326.

  As shown in FIGS. 9A and 9B, the large-diameter portion 124b has a neck portion (illustrated) in the large-diameter portion 124b as in the container 100 (FIGS. 2 and 3) of the first embodiment. (Not)) an inward easy music part 322 extending from the side and an outward easy music part 321 are formed. Then, the outward easy-to-curve portion 321 reaches the outward easily-curing portions 331 and 332 at the edge of the bottom portion 130b (that is, between the large diameter portion 124b and the bottom portion 130b). Also, the inward easy music part 322 extends from the neck (not shown) to the bottom advance surface formed by the edges of the inward easy music parts 324 and 326 and the outward easy music part 325. The large-diameter portion 124b is formed with an inwardly easy-to-curve portion 323 extending from the end on the bottom portion 130b side of the inwardly easy-to-curve portion 322 to the outer easily-curved portions 331 and 332 at the edge of the bottom portion 130b. .

  In the example of FIG. 9, the outward easy music part 321 bends outward and the inward easy music part 322 bends inward so that it is sandwiched between the two inward easy music parts 322 when viewed from the front. A recess having a wall as a region sandwiched between the inner easily bent portion 322 and the outer easily bent portion 321 is formed, and the large diameter portion 124b is folded into an H shape. And the inwardly easy music parts 324 and 326 and the outward easy music part 325 that form the bottom advance surface, and the outward easy music part 331 at the edge of the bottom part 130b from the end of the inner music part 322 on the bottom part 130b side. The inwardly bendable portion 323 extending between 332 and the outwardly bendable portions 331 and 332 at the edges of the bottom portion 130b are bent in the bending direction, so that the bottom portion 130b moves toward the bottom advancement surface. . Thus, in the example of FIG. 9 as well, as the viscous liquid contained in the container is squeezed out, the large-diameter portion 124b is folded into the H shape as the container 100 of the first embodiment, so that the bottom portion A recess extending from the advancing surface toward the mouth portion is generated. Therefore, it is possible to make the container stand up so that the storage property of the container becomes high while suppressing deterioration due to oxidation or the like of the viscous liquid stored in the container.

  2, 3, and 9, although the arrangement | positioning aspect of the easy music part was illustrated, the arrangement | positioning aspect of an easy music part is not necessarily limited to these illustration content. In general, the easy-to-curve portion has the large-diameter portions 124 and 124b of the container 100 so that the large-diameter portions 124 and 124b have concave portions 190 extending from the bottom advancement surface toward the mouth portion 110 (FIG. 7). While being folded inward, the bottom 130 can be arranged in various modes that can be moved toward the bottom advancement surface while being orthogonal to the container axis.

  In order to form a recess extending from the bottom advancement surface toward the mouth in the large diameter portions 124, 124b, for example, at least one inwardly bending portion 222, 322 extending from the mouth toward the bottom advancement surface, A pair of the outer easily bent portions 221 and 321 extending from the bottom portions 130 and 130b to the mouth portion between the inner easily bent portions 222 and 322 may be formed into at least one set of large diameter portions 124 and 124b. . However, in order to more easily maintain the state in which the bottom portions 130 and 130b are orthogonal to the container axis, it is preferable that the number of the inner easily bent portions 222 and 322 and the outer easily bent portions 221 and 321 be two or more. . In addition, since the inward easy-to-curve portions 222 and 322 and the outward easy-to-curve portions 221 and 321 are all formed in the longitudinal direction of the container 100, the longitudinal inwardly easy-to-curve portion and the longitudinally outwardly easy portion respectively. It can also be called a music part.

  In order to move the bottom portions 130 and 130 b toward the bottom portion advancement surface, for example, the outwardly easily bent portion 231 at the edge of the bottom portions 130 and 130 b, that is, the connection portion between the bottom portions 130 and 130 b and the large diameter portions 124 and 124 b. , 232, 331, 332, and the first outer side of the edges of the bottom portions 130, 130 b from the ends on the bottom advancement surface side of the inwardly bendable portions 222, 322 extending from the mouth portion toward the bottom advancement surface What is necessary is just to form the inward easy music parts 223,323 extended between the easy music parts 231,331 and the 2nd outward easy music parts 232,332. In addition, since both the 1st outward easy music parts 231 and 331 and the 2nd outward easy music parts 232 and 332 are formed in the edge of the bottom parts 130 and 130b, they are both bottom outward easy music parts. Can be called. Further, between the first outward easy music parts 231 and 331 and the second outward easy music parts 232 and 332, there is an intersection of the bottom outward easy music part and the longitudinal outward easy music part.

  In FIG. 9, the case where the inwardly easy music part and the outward easy music part are formed as in the first embodiment has been described. However, by replacing the easy music part with the biasing part, as shown in FIG. 9. In addition, it is possible to form an inner biasing portion and an outer biasing portion.

D. Variations:
The present invention is not limited to the above-described embodiments, and can be implemented in various modes without departing from the gist thereof. For example, the following modifications are possible.

D1. Modification 1:
In each of the above embodiments, the bendable portion and the urging portion are formed only on the large diameter portions 124 and 124a that are part of the trunk portions 120 and 120a of the containers 100 and 100a. It is good also as what forms in both large diameter part 124,124a and neck part 122,122a. Generally, the easy-to-curve part and the urging part only have to be formed in at least a partial region connected to the bottom part of the body parts 120 and 120a.

D2. Modification 2:
In the first embodiment and the modification of the arrangement of the easy music parts, the outward easy music parts 221, 225 and the inward easy music part 224, the outer easy music part 225 and the inward easy music parts 222, 223, Outward easy music parts 221, 231, 232 and inward easy music parts 223, outward easy music parts 321, 325, 331, 332 and inward easy music parts 326, outward easy music parts 325 and inward music The music parts 322, 323, 324, the outward music parts 321, 331, 332 and the inward music part 323 are each connected at one point, but these music parts are not necessarily connected. There is no need. In addition, since the easy-to-be-curved part is not necessarily connected as described above, the easy-to-turn part extending from the first position to the second position is the second from the vicinity of the first position. An easy-to-bend portion that extends in the vicinity of this position is called a so-called “easy-to-curve” portion.

D3. Modification 3:
Of the easy parts shown in the first embodiment and the modified example of the arrangement of the easy parts, some inward easy parts may be omitted. For example, it is possible to omit the inwardly bending portions 224, 324, and 326 that form part of the outer edge of the bottom advancement surface. Even if these inwardly easy music parts 224, 324, 326 are omitted, the other easy music parts are bent, and the positions where the inward easy music parts 224, 324, 326 are arranged by the atmospheric pressure applied from the outside of the container. Bend inward.

D4. Modification 4:
In the first embodiment and the modification of the arrangement of the easy-to-curve portions, the outward easy-to-curve portions 221 and 321 extending from the mouth side to the bottom portions 130 and 130b reach the bottom portions 130 and 130b. The easy music parts 221 and 321 do not necessarily need to reach the bottom parts 130 and 130b. For example, the outwardly easy-to-curve portions 221 and 321 may stop at the bottom advancement surface, or may stop at the mouth side near the bottom advancement surface. Even if it does in this way, since the outward bending part 221 and 321 will bend outward, since stress will be applied to the extension part so that it may be bent outward, the extension part also becomes easy to bend outward. For this reason, the same effect as that obtained by providing the outward easy-curved portion in the extended portion can be obtained.

D5. Modification 5:
In the first embodiment and the modified example of the arrangement of the easy-to-curve portions, the bottom portions 130 and 130b are moved toward the bottom advancement surface, so that the edges of the bottom portions 130 and 130b, that is, the bottom portions 130 and 130b and the large diameter portion 124, From the end on the bottom advancement surface side of the inwardly easy curvature portions 222, 322 extending from the mouth toward the bottom advancement surface, while forming the outward easy curvature portions 231, 232, 331, 332 at the connection portion with 124b, Inwardly bent portions 223 and 323 extending between the first outer easily bent portions 231 and 331 and the second outer easily bent portions 232 and 332 at the edges of the bottom portions 130 and 130b are formed. These easy music parts 223, 231, 232, 323, 331, 332 can be omitted. Furthermore, you may abbreviate | omit the easy-curvature parts 224,225,324,325 which form the outer edge of a bottom part advance surface. Even in this case, when the concave portion extending from the bottom advancing surface to the mouth is formed in the large diameter portions 124 and 124b as the viscous liquid is squeezed out, the bottom portion 130 is caused by the atmospheric pressure applied from the outside of the container 100. , 130b moves toward the bottom advancement surface. However, in order to move the bottom portions 130 and 130 b toward the bottom advancement surface more reliably, it is preferable to form the easy-to-curve portions 223, 231, 232, 323, 331 and 332.

D6. Modification 6:
In the modified examples 2 to 5, the case where the inwardly easy music part and the outward easy music part are formed has been described. However, in these modified examples, the inward biasing part is replaced with the biasing part. The present invention can also be applied to the case where the outward urging portion is formed.
