And a cap main body 22 attached to 10B. The contact portion 30 of the lid body 21 is formed on the side of the cap 20 that faces the placement surface M (lower side in FIG. 1). In the following description, the side of the cap 20 that faces the mounting surface M is also referred to as “first side”. Further, the side opposite to the first side (the upper side in FIG. 1) is also referred to as “second side”. In the drawing, for convenience of explanation, the direction in which the “first side” faces is indicated by an arrow I, and the direction in which the “second side” faces is indicated by an arrow II.

  As shown in FIGS. 2 and 4, the cap body 22 is formed on the second side, that is, the upper side of the cap 20, and functions as a connecting portion that is detachably attached to the mouth portion 10 </ b> B of the container body 10. Part 40 is included. As shown in FIG. 4, an internal thread portion 40 </ b> A is formed on the inner peripheral surface of the inner cylinder portion 40. Further, although not shown in the drawing, the male screw portion corresponding to the female screw portion 40 </ b> A of the inner cylinder portion 40 is formed in the mouth portion 10 </ b> B of the container body 10. That is, the cap 20 is configured to be attached to the container body 10 by screwing. Note that the method of inserting the cap 20 into the container body 10 is not limited to screwing, and other methods such as fitting may be employed.

  As shown in FIGS. 2-5, the cap main body 22 may be formed in the double cylinder shape. That is, the cap body 22 may further include an outer cylinder portion 43 located on the outer peripheral side of the inner cylinder portion 40 described above. In this case, the cap body 22 has a disk-shaped top plate portion 42 to which the inner cylinder portion 40 and the outer cylinder portion 43 are connected, and the inner cylinder portion 40 and the outer cylinder portion 43 are respectively a top plate. It stands up from the part 42 toward the upper side. Here, as shown in FIG. 4, an example in which the top plate portion 42 extends along the horizontal direction is shown. A spout 41 is formed in the top plate 42, and the spout 41 is connected to the mouth 10 </ b> B when the cap 20 is attached to the mouth 10 </ b> B of the container body 10. Is formed at a position inside the inner cylinder portion 40.

  The outer cylinder portion 43 may be configured to protrude above the inner cylinder portion 40. In this case, preferably, the outer cylinder portion 43 is formed on the shoulder of the container body 10 along the trunk portion 10A of the container body 10 when the cap 20 is attached to the mouth portion 10B of the container body 10 as shown in FIG. It has the extension part 43A extended above the part 10C. The diameter of the extension 43A is set such that the trunk 10A of the container body 10 is appropriately covered from the outside by the extension 43A.

  The lid body 21 is attached to the cap body 22 in order to provide the above-described contact portion 30 that contacts the placement surface M and close the spout 41 of the cap body 22. The lid body 21 includes, for example, a disc-shaped lid body 31 that faces the spout 41 and the top plate portion 42, and a fitting cylinder portion 32 that rises upward from the outer peripheral edge of the lid body 31. The fitting cylinder part 32 of the lid body 21 and the outer cylinder part 43 of the cap body 22 are configured to be fitted to each other. That is, in the present embodiment, attachment of the lid body 21 to the cap body 22 is brought about by fitting between the fitting cylinder portion 32 of the lid body 21 and the outer cylinder portion 43 of the cap body 22.

  Here, for example, as shown in FIGS. 2 and 4, when the lid body 21 is attached to the cap body 22, the central axis of the disk-shaped top plate portion 42 (a straight line passing through the center of the cross section). And the central axis of the disc-shaped lid body 31 (a straight line passing through the center of the cross section) are positioned on a common axis. FIG. 3 shows a point C1 where the common shaft passes through the cap body 22 and a point C2 where the common shaft passes through the lid body 21 when the lid body 21 is attached to the cap body 22. Hereinafter, the point C1 may be referred to as the center C1 of the cap body 22, and the point C2 may be referred to as the center C2 of the lid 21. Furthermore, the part including the centers C1 and C2 through which the common axis passes in the cap 20 may be referred to as the center of the cap 20.

  Further, as shown in FIGS. 3 and 4, a hinge portion 33 connected to both of them may be provided between the fitting cylinder portion 32 of the lid body 21 and the outer cylinder portion 43 of the cap body 22. . Thereby, the lid 21 is rotatable between a state in which the spout 41 is closed and a state in which the spout 41 is opened, with the hinge portion 33 as the rotation axis. The lid body 31 may be formed with a closed cylinder portion 31 </ b> A that is fitted on the outer peripheral surface of the tip end portion of the spout 41 and closes the spout 41 when the lid 21 is in a state of closing the spout 41. . Accordingly, it is possible to more reliably prevent the contents from leaking out from the spout 41 when the lid 21 is in a state where the spout 41 is closed.

  When the hinge part 33 is provided between the lid body 21 and the cap body 22 as described above, preferably, the above-described spout 41 is provided on the side of the cap body 22 on which the hinge part 33 is provided. Is formed on the opposite side. Here, the “opposite side” means that the spout 41 is not located near the hinge portion 33 with the center C1 of the cap body 22 as a boundary. In other words, it means that the hinge part 33 is arranged on one side with the center C1 of the cap body 22 in between, and the spout 41 is arranged on the other side. This prevents the lid 21 and the hand from interfering when the user opens the lid 21 and pours the contents from the spout 41 toward the user's hand, for example. Can do.

  As long as the tube container 1 can be stably supported in an upright state, the specific form of the contact portion 30 of the lid 21 is not particularly limited. For example, in the present embodiment, as shown in FIG. 4, the lid body 21 has an annular rib 34 that projects downward from the outer peripheral edge of the lid body 31, and the lower end of the rib 34 is in contact with the lid body 21. Part 30. Although not shown, when such a rib 34 is not present, the lower surface of the lid body 31 may function as the contact portion 30.

  Next, the cap 20 is used to support the other end portion of the trunk portion 10A, that is, the portion including the closing portion 10E so as to hold the container body 10 with the mouth portion 10B of the container body 10 facing upward (upright state). The elements formed in the above will be described. In the following description, the elements of the cap 20 for holding the container body 10 in an upright state are collectively referred to as “supporting portion”. Here, as shown in FIGS. 2 to 5, the support part is configured as a pair of slits 44 formed in the outer cylinder part 43 with the center C <b> 1 of the cap 20 interposed therebetween.

  In the present embodiment, the slit 44 is formed at a portion that is opposed in the radial direction of the above-described extension portion 43A formed in the outer cylinder portion 43, and extends from the tip of the extension portion 43A to the top plate portion 42 side. Yes. In this case, the slit 44 is defined by a pair of opposing wall surfaces extending from the tip of the extension portion 43A to the top plate portion 42 side, and a wall surface continuous to the end portion of the pair of wall surfaces on the top plate portion 42 side. ing. In the present embodiment, the width dimension of the slit 44 is set to a dimension capable of receiving and clamping a portion of the closing portion 10E and the body portion 10A adjacent to the closing portion 10E. For example, in the present embodiment, the slit 44 is configured such that the width gradually decreases from the distal end of the extension portion 43A toward the top plate portion 42 side. As an example, the slit 44 having such a shape allows the container body 10 to stand upright by fitting the closed portion 10E of the trunk portion 10A and a portion of the trunk portion 10A adjacent to the closed portion 10E into the slit 44. Can be held in a state. In addition, the part adjacent to the closing part 10E of the closing part 10E of the trunk part 10A and the trunk part 10A may be fitted into the slit 44 with play (gap) or may be press-fitted without play. Moreover, in this Embodiment, the site | part corresponding to the "other end part of a trunk | drum" inserted by a support part (slit 44) is a site | part adjacent to the closure part 10E among the closure part 10E and trunk | drum 10A. It has become. However, the part corresponding to such “the other end portion of the body portion” may be changed depending on the shape and size of the support portion (slit).

  By the way, from the viewpoint of the sealing performance between the container body 10 and the cap 20, it can be said that the above-described slit 44 acts to lower the sealing performance. On the other hand, in the present embodiment, as described above, the slit 44 is formed in the extending portion 43A extending along the trunk portion 10A so as to cover the trunk portion 10A of the container body 10. For this reason, by configuring the extension portion 43A so that the gap between the extension portion 43A and the body portion 10A is as small as possible, preferably the two portions are in close contact with each other. Even if it reaches, the body portion 10A can prevent the liquid from entering the inside of the cap 20. Therefore, the slit 20 (support part) for holding the container main body 10 in an upright state can be provided in the cap 20 with no or almost no decrease in the sealing performance between the container main body 10 and the cap 20.

  In addition, when the slit 44 is provided in the extension 43A in order to prevent the sealing performance between the container main body 10 and the cap 20 from being deteriorated by the slit 44, except for the place where the slit 44 is formed, It can be said that there is no particular need to provide such an extension 43A. Therefore, as shown in FIGS. 1, 2, 4, and 5, at a position between the pair of slits 44 apart from the slit 44, the outer cylinder portion 43 has a pair of cuts in which the extension portion 43A is cut out. A notch 46 may be formed. In other words, the notch 46 may be formed in a region of the extension 43A where the slit 44 is not formed. Accordingly, the amount of the resin material used for forming the outer cylinder portion 43 can be reduced as compared with the case where the extension portion 43 </ b> A is formed over the entire area of the outer cylinder portion 43. Note that, in improving the sealing performance between the container body 10 and the cap 20, the extension 43 </ b> A acts effectively regardless of the presence or absence of the slit 44. Accordingly, the extension 43 </ b> A may be formed over the entire area of the outer cylinder portion 43 except for the slit 44.

  As a material of the cap 20, a thermoplastic resin such as polypropylene is used. The manufacturing method of the cap 20 is not particularly limited. For example, the cap 20 including the lid body 21, the cap body 22, and the hinge portion 33 is integrally formed by using an injection molding method or a compression molding method. Can do.

  Next, the operation of the tube container 1 according to the first embodiment will be described.

  First, a method for using the contents stored in the tube container 1 will be described. While the contents are present in the tube container 1, the container body 10 is usually in an inverted state with the cap 20 attached to the mouth portion 10 </ b> B of the container body 10, with the lid 21 of the cap 20 facing down. Is retained. When using the tube container 1, the tube container 1 is lifted, the lid body 21 is removed from the cap body 22, and the spout 41 is exposed to the outside. In this state, the contents are discharged from the spout 41 by squeezing the container body 10.

  Next, a method for replenishing the contents in the tube container after the contents in the tube container 1 are used up will be described. First, a bottle or pouch (not shown) filled with contents is prepared. Next, the cap 20 is removed from the container body 10 of the tube container 1 to open the mouth portion 10B. Then, the cap 20 is placed on the placement surface M with the contact portion 30 of the lid 21 of the cap 20 facing downward. At this time, in the cap 20, as shown in FIG. 2, the open end of the slit 44 in the cap body 22 faces upward. Each of the slits 44 facing each other across the center of the cap 20 is adjacent to the closed portion 10E of the container body 10 and the trunk portion 10A of the container body 10B in which the mouth portion 10B faces upward. Insert the part. As a result, as shown in FIG. 6, the container body 10 can be held with the mouth portion 10B facing upward. During this state, the contents can be poured into the container body 10 through the mouth portion 10B facing upward.

  Thus, according to the present embodiment, the cap 20 of the tube container 1 is connected to the mouth portion 10B on the one end side of the container body 10 so as to hold the container body 10 in an inverted state (inner In addition to the tube portion 40), the tube body 10 has a support portion (slit 44) that supports the other end portion of the container body 10 so as to hold the container body 10 in an upright state. As described above, the cap 20 is configured to be capable of both holding the container body 10 in an inverted state and holding it in an upright state. For this reason, the upright state of the container main body 10 of the tube container 1 can be easily implement | achieved, without adding a component newly. Therefore, according to this Embodiment, the new value excellent in the economical aspect and the environmental aspect of the refillability improvement can be added to the tube container 1 excellent in portability cheaply.

  Various changes can be made to the above-described embodiment. Hereinafter, modified examples will be described with reference to the drawings as necessary. In the following description and the drawings used in the following description, the same reference numerals as those used for the corresponding parts in the present embodiment are used for the parts that can be configured in the same manner as the present embodiment. And redundant description is omitted. In addition, when it is clear that the operational effects obtained in the above-described embodiment can be obtained in the modified example, the description thereof may be omitted.

(Slit variants)
FIG. 7 is a side view of a cap according to a modification of the first embodiment. In the cap according to the modification shown in FIG. 7, projecting pieces 48 projecting in a direction in which the pair of wall surfaces oppose each other on a pair of opposing wall surfaces of the extension portion 43 </ b> A (outer cylinder portion 43) that defines the slit 44. Is formed. In this example, a projecting piece 48 is formed in a region on the open end side of the slit 44 in a pair of opposing wall surfaces of the extension portion 43A. By providing such a projecting piece 48, the width dimension of the slit 44 in the region where the projecting piece 48 is provided can be locally reduced compared to the region where the projecting piece 48 is not provided. Thereby, the clamping force which the slit 44 exerts on the trunk portion 10A can be locally increased. As a result, as will be described later, the stability of the container body 10 in the upright state can be effectively improved.

  As shown in FIG. 7, the projecting piece 48 may be formed in a triangular shape that tapers in the projecting direction. Accordingly, the degree of change in the width dimension of the slit 44 when the closing portion 10E of the trunk portion 10A inserted into the slit 44 from the upper side reaches the distal end portion in the protruding direction of the projecting piece 48 is relatively gentle. It can be. Thereby, the closing portion 10E of the trunk portion 10A can be smoothly guided into the slit 44. In this respect, this modification is different from the first embodiment.

  Hereinafter, the operation brought about by the slit 44 according to this modification will be described. When the body portion 10 </ b> A of the container body 10 is fitted to the back of the slit 44, if there is a play (gap) between the body portion 10 </ b> A and the slit 44, the container body 10 is placed behind the slit 44. It tries to incline about the edge of the closure part 10E located as a rotating shaft. However, when the projecting piece 48 is formed as in the modification described with reference to FIG. 7, the projecting piece 48 interferes with the body portion 10 </ b> A of the container main body 10 to be inclined, and the container main body 10 is inclined. Can be suppressed. That is, according to the slit 44 of this modified example, not only the closing portion 10E of the trunk portion 10A but also a portion of the trunk portion 10A that is separated from the closing portion 10E toward the mouth portion 10B can be securely clamped. For this reason, the stability of the upright state of the container body 10 can be improved. Further, in the modified example of FIG. 7, since the projecting piece 48 is formed in the open end side region of the slit 44 in the pair of opposing wall surfaces of the extension portion 43A, the closing portion 10E and the trunk portion 10A are formed. The space between the portions sandwiched by the projecting pieces 48 can be made wider. For this reason, compared with the case where the protrusion 48 is formed in the area | region of the back side of the slit 44, the inclination of the container main body 10 can be suppressed more effectively. Thereby, the stability of the container body 10 in the upright state can be effectively improved.

  In the modification described with reference to FIG. 7, the example in which the projecting pieces 48 are formed on each of the pair of opposing wall surfaces of the extending portion 43 </ b> A that defines the slit 44 is shown. However, the specific configuration of the projecting piece 48 is not particularly limited as long as a portion of the trunk portion 10A that is spaced from the closing portion 10E toward the mouth portion 10B can be supported. For example, although not illustrated, a protruding piece that protrudes toward the other may be formed on only one of a pair of opposing wall surfaces of the extension portion 43A.

(Modification of outer cylinder)
Next, another modification of the first embodiment will be described. FIG. 8 is a longitudinal sectional view of a cap according to another modification of the first embodiment. In the modification shown in FIG. 8, the notch 46 described in the first embodiment is not formed in the extension 43 </ b> A of the outer cylinder 43 of the cap body 22. That is, the extended portion 43 </ b> A is formed over the entire outer peripheral portion 43 except for the portion where the slit 44 is formed. In this respect, this modification is different from the first embodiment.

  According to the modification described with reference to FIG. 8, since the sealing performance between the container body 10 and the cap 20 is improved, the liquid can be more effectively prevented from entering the inside of the cap 20.

(Modified cap body)
Next, still another modification of the first embodiment will be described. FIG. 9 is a longitudinal sectional view of a cap according to still another modification of the first embodiment.

  In the above-described first embodiment and each modification, the connection portion connected to the mouth portion 10B of the container body 10 is configured by the inner cylinder portion 40 of the cap 20, and supports the other end portion of the container body 10. The example in which the support part for this is provided in the outer cylinder part 43 of the cap 20 was shown. That is, the example in which the connection portion and the support portion are different elements has been shown. However, the present invention is not limited to this, and the connection portion and the support portion may be included in one cylindrical portion of the cap 20 as described in this modification.

  In the present modification shown in FIG. 9, the cap body 22 is not formed in a double cylinder shape as in the first embodiment. Specifically, the cap body 22 is a disc-shaped top plate in which a spout 41 communicating with the mouth portion 10B of the container body 10 is formed when the cap 20 is attached to the mouth portion 10B of the container body 10. Part 42 and a connecting cylinder part 50 erected upward from the outer peripheral edge of the top plate part 42.

  An internal thread portion 50 </ b> A for attaching the cap 20 to the mouth portion 10 </ b> B of the container body 10 is formed in a region on the top plate portion 42 side of the connecting tube portion 50. On the other hand, in the region from the upper end (the end closer to the second side) of the region where the female screw portion 50A is formed in the connection tube portion 50 to the tip of the connection tube portion 50, the same as in the first embodiment. The slit 44 and the notch 46 are formed. In the illustrated example, the connecting tube portion 50 is formed in a two-stage tube shape, and the region of the connecting tube portion 50 where the slit 44 and the cutout portion 46 are formed is the same as the connecting tube portion 50. It has a larger diameter than the region where the female screw portion 50A is formed, and corresponds to the extension portion 43A described in the first embodiment. The mouth portion 10B of the container body 10 is screwed to the female screw portion 50A, and the shoulder portion 10C protruding from the mouth portion 10B is formed with the slit 44 and the notch portion 46 of the connecting tube portion 50. Extending towards the area. The trunk portion 10A extending upward from the outer peripheral edge side of the shoulder portion 10C is covered from the outside by the region of the connecting tube portion 50 where the slit 44 and the notch portion 46 are formed. As described above, the connection cylinder portion 50 of the cap 20 includes both the connection portion connected to the mouth portion 10B of the container body 10 and the slit 44 that functions as a support portion that supports the other end portion of the container body 10. It is. Therefore, using the cap 20 having a simpler configuration, the same effects as those of the first embodiment can be achieved. In this respect, this modification is different from the first embodiment.

  In the example shown in FIG. 9, the slit 44 does not extend to the region where the female thread portion 50 </ b> A of the connecting cylinder portion 50 is formed. However, the slit 44 is not limited to this and is not illustrated. You may extend to the area | region in which 50 A of internal thread parts were formed.

(Second Embodiment)
FIG. 10 is a diagram showing the cap in a state where the cap lid according to the second embodiment has opened the spout of the cap body, and FIG. 11 is a longitudinal section of the cap according to the second embodiment. FIG. 12 is a side view of a cap according to the second embodiment. FIG. 13 is an arrow view seen in the direction of arrow 13 in FIG. Components in the present embodiment that are the same as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Moreover, when it is clear that the effect obtained in the first embodiment can be obtained in the present embodiment, the description thereof may be omitted.

  First, main differences between the cap 20 in the first embodiment described above and the cap 20 in the present embodiment will be described. As shown in FIGS. 10 to 13, in the present embodiment, the top plate portion 42 is provided on the top plate portion 42 of the cap body 22 from the second side to the first side, that is, from the upper side to the lower side. A first drain hole 60 penetrating therethrough is formed. Further, the top plate portion 42 of the cap body 22 has an inclined surface 70 that extends in a direction inclined toward the first side (lower side) with respect to the horizontal direction as it goes toward the first drain hole 60. Further, the lid body 21 is formed with a second drain hole 61A penetrating the lid body 21 from the second side to the first side, that is, from the upper side to the lower side. As will be described later, the first drain hole 60 and the second drain hole 61A are for discharging liquid such as water that has entered the cap 20 from the outside to the outside.

  Next, the 1st drain hole 60 of the top-plate part 42 is demonstrated in detail. When the cap main body 22 includes the inner cylindrical portion 40 and the outer cylindrical portion 43, the top plate portion 42 of the cap main body 22 is a disc-shaped central circle located inside the inner cylindrical portion 40 as shown in FIG. It is divided into a plate part 42A and an annular outer peripheral disk part 42B located between the inner cylinder part 40 and the outer cylinder part 43. A spout 41 is formed in the central disc part 42A. And the above-mentioned 1st drain hole 60 is formed in the outer peripheral side disk part 42B, as shown in FIG. That is, the first drain hole 60 is formed in a region between the inner cylinder part 40 and the outer cylinder part 43 in the top plate part 42.

  As shown in FIG. 11, the 1st drain hole 60 may be formed in the position adjacent to the hinge part 33 in the outer peripheral side disk part 42B. In general, the user's attention is not so suitable for the area near the hinge portion 33, so that the first water drain hole 60 can be prevented from being noticeable by providing the first water drain hole 60 near the hinge portion 33. . As described above, when the spout 41 is provided on the side of the cap body 22 opposite to the side on which the hinge portion 33 is provided, the spout 41 is disposed on one side across the center of the cap 20. Thus, the first drain hole 60 is disposed on the other side.

  In the present embodiment, as shown in FIG. 10, the first drain hole 60 is formed in an arc shape or a bow shape extending in the circumferential direction of the outer peripheral side disk portion 42 </ b> B. The advantage of adopting such a shape will be described later.

  Next, the inclined surface 70 of the top plate part 42 will be described in detail. The inclined surface 70 is provided so that a liquid such as water that has reached the top plate portion 42 naturally moves toward the first drain hole 60 by gravity. In the present embodiment, as described above, the first drain hole 60 penetrates the outer peripheral disc portion 42B from the second side to the first side in the outer peripheral disc portion 42B of the top plate portion 42. Therefore, the inclined surface 70 is also formed on the second side (upper side) surface of the outer circumferential disc part 42B. Specifically, as shown in FIGS. 11 and 12, the outer circumferential disk portion 42 </ b> B is inclined in the direction inclined to the first side (lower side) with respect to the horizontal direction as it goes toward the first drain hole 60. It is formed to extend. The inclination angle of the inclined portion 70 is not particularly limited, but is set within a range of 2 to 30 °, for example.

  In the present embodiment, the inclined surface 70 is formed in the entire area of the outer peripheral disk portion 42B. That is, an inclination toward the first drain hole 60 is given to the entire area of the outer peripheral disk portion 42B. However, it is not restricted to this, The inclined surface 70 may be partially formed in the outer peripheral side disc part 42B. Further, in the present embodiment, the central disc portion 42A is shown as extending in the horizontal direction, but the present invention is not limited to this, and the central disc portion 42A and the outer peripheral disc portion 42B are integrated. It may be formed in an inclined shape. That is, the inclined surface 70 may be formed over the central disc part 42A and the outer peripheral disc part 42B.

  Next, the second drain hole 61A of the lid 21 will be described in detail. As shown in FIG. 11, the second drain hole 61 </ b> A is formed adjacent to the hinge portion 33 on the side of the lid body 21 where the hinge portion 33 is provided. And as shown in FIG. 11, in the state which the cover body 21 closes the spout 41, 60 A of 1st drain holes and 61 A of 2nd drain holes oppose. Further, in this example, the second drain hole 61 </ b> A is formed in an arc shape or an arc shape extending in the circumferential direction of the lid body 31 in the same manner as the first drain hole 60 of the cap body 22.

  Next, the shape of the first drain hole 60 and the second drain hole 61A will be described in more detail. FIG. 10 shows an angle X around the center of the cap 20 in the first drain hole 60 and an angle Y1 around the center of the cap 20 in the second drain hole 61A. In the present embodiment, the angle X and the angle Y1 are set to be substantially the same. Specific values of the angle X and the angle Y1 are appropriately set based on the ease of liquid removal required for the cap 20, strength, appearance, and the like. For example, the first drain hole 60 and the second drain hole 61 </ b> A are formed as holes continuously extending in the range of 5 ° to 75 ° around the center of the cap 20. FIG. 10 shows an example in which the angle X and the angle Y1 are both about 45 °. That is, the first drain hole 60 and the second drain hole 61A are each formed as a hole continuously extending in the range of about 45 ° around the center of the cap 20.

  The number of drain holes formed in the cap body 22 and the number of drain holes formed in the lid body 21 are not particularly limited. For example, as shown in FIG. 10, the lid body 21 may further include second drain holes 61B, 61C, 61D in addition to the second drain hole 61A. These four second drain holes 61A, 61B, 61C, 61D are formed, for example, at intervals of approximately 90 ° in the circumferential direction at the outer peripheral portion of the lid body 31 of the lid body 21. As shown in FIG. 11, the second drain holes 61 </ b> A, 61 </ b> B, 61 </ b> C, 61 </ b> D are all formed at positions surrounded by the ribs 34 in the lid main body 31.

  In FIG. 10, the angle Y2 around the center of the cap 20 of the second drain hole 61B is shown together with the angle X and the angle Y1 described above. The angle Y2 is about 10 °. That is, the second drain hole 61 </ b> B is formed as a hole continuously extending in the range of about 10 ° around the center of the cap 20.

  It should be noted that most of the liquid that reaches the lid 21 side through the first drain hole 60 of the cap body 22 reaches the second drain hole 61 </ b> A at the position facing the first drain hole 60 and reaches the second drain hole 61 </ b> A. 2 It is considered that the water is discharged from the drain hole 61A. Therefore, holes other than the second drain hole 61A among the second drain holes formed in the lid body 21, that is, the second drain holes 61B, 61C, 61D are not discharged from the second drain hole 61A. It can be said that this is a supplement for discharging a small amount of liquid. Therefore, the second drain holes 61B, 61C, 61D described above may be formed in a circular shape having an opening area smaller than that of the second drain hole 61A. Thereby, compared with the case where four holes having the same dimensions as the second drain hole 61A are formed in the lid body 21, it is possible to suppress a decrease in strength and design of the lid body 21 due to the holes. it can.

  Hereinafter, the operation of the tube container 1 according to the present embodiment will be described. According to the present embodiment, when a liquid such as water enters the radial direction of the outer cylinder portion 43 in the top plate portion 42, the liquid is shown in FIG. It is guided to the first drain hole 60 by the inclined surface 70 of 42 and discharged to the outside of the first drain hole 60. Thereafter, the liquid discharged to the outside of the first drain hole 60 can be discharged to the outside of the lid body 21 through the second drain hole 61A, 61B, 61C, 61D. Thereby, it is possible to suppress the occurrence of mold or the like due to the liquid remaining in the cap 20 or the scattering of the liquid when the lid 21 is removed.

  Further, as described above, the slit 44 formed in the cap 20 acts to reduce the sealing performance between the container body 10 and the cap 20. Here, according to the present embodiment, even if the sealing performance between the container body 10 and the cap 20 is lowered by the slit 44, the liquid that has entered the cap 20 is effectively discharged. can do. Accordingly, it is possible to suitably suppress an adverse effect due to a decrease in sealing performance caused by the slit 44.

  In the present embodiment, since the first drain hole 60 and the second drain hole 61A are opposed to each other, the liquid discharged to the outside of the first drain hole 60 is discharged to the second drain hole. It can be efficiently discharged from 61A.

  Also in the present embodiment, as shown in FIG. 11, the rib 21 rising toward the first side (lower side) is formed on the lid 21 (lid body 31). The rib 34 surrounds the second drain holes 61A, 61B, 61C, 61D. In this case, when the container body 10 is held with the contact portion 30 of the rib 34 formed on the lid body 31 in contact with the placement surface M and the mouth portion 10B facing downward, A space is formed between the area inside the rib 34 on the side and the mounting surface M. Accordingly, even when the tube container 1 is placed on the placement surface M, the liquid can be discharged from the second drain holes 61A, 61B, 61C, 61D into the space. For this reason, the liquid on the lid body 31 can be efficiently discharged to the outside of the lid body 31.

  By the way, the inclination of the inclined surface 70 formed in the outer peripheral side disk part 42B of the top plate part 42 of the cap body 22 is generally uniform when the cap body 22 is seen in a sectional view as shown in FIG. The tilt angle is set. However, as shown in FIG. 13, the liquid that has reached the outer peripheral disk portion 42B of the top plate portion 42 is in the first water along a circumferential path defined by the annular outer peripheral disk portion 42B. Head to the hole 60. In this case, the degree of driving force to which the liquid is applied by the inclined surface 70 in the circumferential path varies depending on the position on the outer circumferential disc part 42B. For example, the driving force to which the liquid is applied by the inclined surface 70 in the vicinity of the position where the first drain hole 60 is provided is spaced 90 ° in the circumferential direction from the position where the first drain hole 60 is provided. The liquid is smaller than the driving force applied by the inclined surface 70 at the position. Therefore, it can be said that water is less likely to flow in the vicinity of the first drain hole 60 than in other regions.

  Here, according to the present embodiment, as described above, the first drain hole 60 is formed in an arc shape or an arc shape extending in the circumferential direction of the outer circumferential disc portion 42B. In other words, the region where the water hardly flows in the outer peripheral disk portion 42 </ b> B is the first drain hole 60. Therefore, the liquid such as water that has flowed along the inclined surface 70 from the other region to the region in the vicinity of the first drain hole 60 can reach the first drain hole 60 more reliably.

  Next, a modification of the second embodiment will be described. FIG. 14 is a longitudinal sectional view of a cap according to a modification of the second embodiment. In the modification described here, a part of the second embodiment is changed. Components in the present embodiment that are the same as those in the second embodiment are denoted by the same reference numerals and description thereof is omitted.

  In the modification shown in FIG. 14, the lid body 31 of the lid body 21 has an inclined surface 71 extending in a direction inclined toward the first side (lower side) with respect to the horizontal direction as it goes toward the second drain hole 61A. doing. Correspondingly, the rib 34 is formed such that its height gradually decreases toward the second drain hole 61A.

  According to this modification, liquid such as water discharged to the outside of the first drain hole 60 is guided to the second drain hole 61A by the inclined surface 71 of the lid body 21, and the second drain hole 61A. Is discharged outside. Thereby, the liquid that has entered the inner side of the outer cylinder portion 43 in the top plate portion 42 in the radial direction can be effectively discharged.

  FIG. 15 is a longitudinal sectional view of a cap according to another modification of the second embodiment. In the modification shown in FIG. 15, the top plate portion 42 of the cap body 22 does not have the above-described inclined surface 70, while only the lid body 31 of the lid body 21 has the inclined surface 71. Further, the lid body 31 is not formed with the above-described second drain hole 61 </ b> A facing the first drain hole 60 of the cap body 22, while sandwiching the center of the first drain hole 60 and the cap 20. Only the second drain hole 61B located on the opposite side is formed. Further, the inclined surface 71 of the lid body 21 extends in a direction inclined toward the first side (lower side) with respect to the horizontal direction as it goes toward the second drain hole 61B. This is different from the modification described with reference to FIG.

  According to this modification, liquid such as water discharged from the first drain hole 60 is guided by the inclined surface 71 to the second drain hole 61 </ b> B located away from the first drain hole 60. The liquid that has entered the cap 20 can be effectively discharged regardless of the position of the drain hole formed in the lid 21. For this reason, it is possible to ensure the degree of freedom of arrangement of the drain holes formed in the lid body 21 while ensuring good liquid discharge performance. In addition, the inclination direction of the inclined surface 71 and the position of the drain hole formed in the lid 21 are not limited to the aspect of the modification described in FIG.

  As mentioned above, although each embodiment of the present invention was described, the present invention is not limited to the composition of the above-mentioned embodiment. For example, in the above-described embodiment, the body portion 10A is formed in a cylindrical shape by adhering side edges of a laminate film including a base material form and a sealant film laminated by a dry laminating method by heat sealing or the like. The container main body 10A is formed by bonding or the like to the connecting body 100 having the mouth portion 10B or the like at the opened one end portion. However, the body portion 10A may be formed in a cylindrical shape by a melt extrusion molding method, and the coupling body 100 may be bonded thereto. Further, the body portion 10A and the mouth portion 10B (shoulder portion 10C) may be integrally formed by blow molding.
