[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-104460 Summary of the Invention [Problem to be solved by the invention]
[0004] When the shoulder of a container is entirely covered by the base of a cap, it is difficult to crush the upper end of the body, making it difficult to remove the contents near the shoulder. The present invention has been made in consideration of these circumstances, and aims to provide a tube container that allows easy removal of the contents while maintaining its self-standing and appearance. [Means for solving the problem]
[0005] In order to solve the above problems, the tube container 10, 10A of the present invention is a tube container that includes a body 15, a shoulder 16 extending to narrow one end of the body 15, a connecting portion 13 having a discharge outlet 29 protruding from the shoulder 16, a base 14 connected to the connecting portion 13, and a lid portion 25 connected to the base 14 by a hinge 23, and can stand on its own with the lid portion 25 facing axially downward, wherein the outer periphery of the base 14 is defined by a first wall portion 21, and the outer periphery of the lid portion 25 is defined by a second wall portion 30, the shoulder portion 16 has an exposed area that is not covered by the first wall portion 21 and can be contacted by fingers, and the second wall portion 30 surrounds the exposed area when the lid is closed and is positioned at a position with a gap S between it and the shoulder portion 16 in the axial direction.
[0006] It is preferable that the lid portion 25 includes a third wall portion 31, and when the lid is closed, the open end of the third wall portion 31 abuts against the base portion 14. It is also preferable that the lid portion 25 includes a plug portion 34 that closes the discharge port 29 of the connecting portion 13, and when the lid is closed, a closed annular space is formed by the third wall portion 31 and the plug portion 34. It is also preferable that the thickness t1 of the shoulder portion 16 is greater than the thickness t2 of the body portion 15.
[0007] It is preferable that the shoulder portion 16 extends in a direction substantially perpendicular to the axis J of the body portion 15. Furthermore, it is preferable that a transition portion 17 is provided between the shoulder portion 16 and one end of the body portion 15, and that the transition portion 17 has a step portion 17a extending from one end of the body portion 15 to the distal end, and that the body portion 15 and the shoulder portion 16 are connected via the step portion 17a. In this case, it is preferable that the second wall portion 30 is positioned inside the step portion 17a when the lid is closed. It is also preferable that the lid portion 25 has a top plate 33 and the second wall portion 30 rising from its peripheral edge, and that a drainage hole 33a is formed near the peripheral edge of the top plate 33, and that a recess 33b is formed on the upper surface of the top plate 33 from the periphery of the drainage hole 33a toward the peripheral edge of the top plate 33. [Effects of the Invention]
[0008] According to the tube container of the present invention, the shoulder is covered by the lid when closed, maintaining the appearance and self-standing. Furthermore, when the lid is opened, the exposed area of the shoulder can be touched with the fingers, facilitating removal of contents when only a small amount remains. Furthermore, because the size of the base is smaller than that of the lid, the overall amount of material for the cap can be reduced.
[0009] The lid preferably has a third wall, the open end of which abuts against the base when closed, thereby determining the position of the lid when closed and allowing the tube container to stand stably. The third wall also prevents damage to the lid due to the impact of a drop.
[0010] The lid may have a plug that closes the outlet of the connecting portion, and when the lid is closed, a closed annular space is formed by the third wall and the plug that closes the outlet of the base portion. This allows the contents that have adhered to the periphery of the outlet to remain within this space, thereby preventing the outside from becoming soiled.
[0011] The thickness of the shoulder is preferably greater than that of the body, which prevents deformation of the shoulder when a finger touches the shoulder to remove contents remaining near the shoulder. This prevents the second wall from interfering with the shoulder when the lid is closed, and prevents the gap between the second wall and the shoulder from widening.
[0012] The shoulder may be substantially perpendicular to the axis of the body. This makes it easier to bring the inner surface of the body closer to the inner surface of the shoulder, compared to when the shoulder has a shape such as a cone that protrudes axially upward beyond the end of the body, making it easier to remove contents near the shoulder. Furthermore, the axial length of the second wall can be shorter than when the shoulder protrudes axially upward beyond the end of the body. This reduces the amount of material used for the cap.
[0013] The shoulder may be substantially perpendicular to the axis of the body, and a transition portion may be provided between the shoulder and one end of the body, with the transition portion having a step extending from one end of the body to the distal end, and the shoulder may be connected to the body via the step. This makes it easier to remove contents near the shoulder. The step also functions as a gap to prevent interference between the lid and the shoulder when the lid is closed. This gap is hidden by the transition portion, which is connected axially above the shoulder, thereby maintaining a desirable appearance. Furthermore, with regard to the resistance to deformation of the outer periphery of the shoulder, when comparing containers with and without a step under the same conditions for the thickness of the shoulder and transition portion, the presence of the step makes the outer periphery of the shoulder less likely to deform. Therefore, the appearance is maintained and the closed state can be stabilized until the contents are consumed.
[0014] The second wall portion is preferably positioned inside the step portion when the lid is closed, thereby making the gap between the end of the second wall portion and the shoulder portion less noticeable and maintaining an excellent appearance. If the lid portion has a top plate and the second wall portion rising from its peripheral edge, and if a drainage hole is formed near the peripheral edge of the top plate and a recess is formed on the upper surface of the top plate from around the drainage hole toward the peripheral edge, moisture that accumulates in the lid portion of an inverted tube container can be easily drained.

[0016] Hereinafter, an embodiment of the tube container of the present invention will be described with reference to the drawings. The tube container 10 shown in FIG. 1 comprises a container body 11 and a hinge cap 12 attached to the container body 11. The container body 11 and the hinge cap 12 are manufactured separately and assembled by connecting a base portion 14 of the hinge cap 12 to a connecting portion 13 of the container body 11. However, the two may also be integrated by thermal welding. In the following description, when referring to the up-down direction, the side with the hinge cap 12 is referred to as the top, as in the state shown in FIG. 1.
[0017] As shown in FIG. 2, the container body 11 has a cylindrical body 15, a shoulder 16 extending to narrow one end of the body 15, and a cylindrical connecting portion 13 protruding from near the center of the shoulder 16. The body 15 can be manufactured by welding the side edges of a single-layer or multi-layer synthetic resin sheet or a laminate of a synthetic resin sheet and metal foil together to form a cylindrical shape. The body 15 may also be made of a member obtained by extruding a single-layer or multi-layer synthetic resin into a cylindrical shape. A gas-impermeable synthetic resin may be used instead of metal foil. As shown in FIG. 1, the bottom end 15a of the body 15 is open, and after the contents are filled into the bottom end 15a, it is closed by collapsing, rolling, or welding (see the two-dot chain line 15b).
[0018] As shown in FIG. 2A, shoulder portion 16 is flat and disposed in a direction perpendicular to axis J. Flattening shoulder portion 16 makes it easier to squeeze out the contents around shoulder portion 16 after they have been used up. Shoulder portion 16 can be manufactured together with connecting portion 13 by injection molding or the like. It is preferable that thickness t1 of shoulder portion 16 be thicker than thickness t2 of body portion 15. Thickness t1 of body portion 15 is, for example, about 0.3 to 0.6 mm, and thickness t2 of shoulder portion 16 is, for example, about 0.8 to 2.0 mm, more preferably about 1.0 to 1.2 mm.
[0019] As shown in FIG. 2A, the connecting portion 13 is cylindrical, and its interior is a passage for pushing out the contents. There is a smooth connection from the inner surface of the shoulder portion 16 to the inner surface of the connecting portion 13. The upper end surface 13a of the connecting portion 13 is flat. A male thread 13b that screws into the hinge cap 12 is formed around the periphery of the connecting portion 13. The shoulder portion 16 and the body portion 15 can be manufactured separately and then joined by welding or the like. Alternatively, the upper end of the cylindrically molded body portion 15 can be placed in a mold having a cavity corresponding to the shoulder portion 16 and the connecting portion 13, and molded integrally with the body portion 15 by injecting molten resin into the cavity or by compressing the molten resin within the cavity.
[0020] In this embodiment, a transition section 17 is provided between the upper end of the body section 15 and the periphery of the shoulder section 16. The transition section 17 has a step section 17a extending from the upper end of the body section 15 toward the lower end of the container body 11, and this step section 17a connects the upper end of the body section 15 to the periphery of the shoulder section 16. This transition section 17 can be formed by providing an annular protrusion 16a having an arc-shaped or semicircular cross section on the periphery of the shoulder section 16. The annular protrusion 16a has approximately the same thickness as the flat section of the shoulder section 16 at the inwardly tapering step section 17a, and gradually becomes thinner from the upper end to the outer side. The upper end of the body section 15 is welded along the arc-shaped cross-sectional surface of the annular protrusion 16a. The axial difference d between the upper end of this annular protrusion 16a and the inner lower end is the dimension of the step section 17a.
[0021] The provision of such a transition portion 17 makes it easier to remove contents from near the shoulder portion 16. Furthermore, as shown in FIG. 2B , the step portion 17a functions as a gap S that prevents interference between the lid portion 25 and the shoulder portion 16 when the lid is closed. This gap S is hidden by the transition portion 17, which extends upward from the shoulder portion 16, thereby maintaining a desirable appearance. Furthermore, the provision of the step portion 17a increases the rigidity of the outer periphery of the shoulder portion 16, making it less likely to deform. Therefore, when the tube container 10 is stood upright, a desirable appearance is maintained until all the contents are consumed, and the closed state can be stabilized. The gap S may have an axial length of, for example, about 0.5 to 3 mm, but is not limited to this range.
[0022] 2B and 3A-C, hinge cap 12 comprises base portion 14 that is screwed onto connecting portion 13 of container body 11, and lid portion 25 that is flexibly connected to base portion 14 via hinge 23 and spring 24. Base portion 14 does not have a shoulder cover that covers the shoulder of the container body, as in conventional hinge caps. Instead, lid portion 25 covers a wide area of shoulder portion 16, thereby fulfilling part of the shoulder cover function.
[0023] Base portion 14 includes a first wall portion 21 that is screwed into connecting portion 13, and a support portion 22 that extends radially outward from first wall portion 21. Support portion 22 is an extension that connects first wall portion 21 with hinge 23 and spring 24. Spring 24 is a leaf spring that biases lid portion 25 in the closing direction from the middle of its bending in the closing direction, and biases lid portion 25 in the opening direction from the middle of its bending in the opening direction.
[0024] The first wall portion 21 is cylindrical and defines the outer periphery of the base portion 14. An internal thread 21a is formed on the internal surface of the first wall portion 21 to threadably engage with the external thread 13b of the connecting portion 13. The upper end 21b (the lower end in FIG. 2B ) of the first wall portion 21 has an annular engaging portion 26 that extends inward to engage with the upper end surface 13a of the connecting portion 13, a fitting tube 27 that protrudes downward from the internal edge of the engaging portion 26 and fits with the internal surface of the first wall portion 21, and a closing portion 28 that closes the upper end opening of the connecting portion 13. A discharge port 29 through which the contents are pushed out is formed in the closing portion 28.
[0025] An annular fitting step 32 is formed on the outer periphery of the upper end of first wall 21, into which the lower end of third wall 31 of the lid is fitted. Support 22 has a U-shaped cross section and, as shown in Fig. 3B, includes two side walls 22a extending substantially parallel to each other, an upper wall 22b closing the upper surfaces of side walls 22a, and an arc-shaped peripheral wall 22c closing the outer periphery of side wall 22a (see Fig. 5). Arc-shaped peripheral wall 22c is flush with second wall 30 that defines the periphery of lid 25 when lid 25 is closed, so that the two form a single cylinder.
[0026] Lid portion 25 has a generally cylindrical shape and is made up of a generally circular top plate 33 and a second wall portion 30 that rises from the periphery of top plate 33 and defines the outer periphery of lid portion 25. Lid portion 25 further includes a stopper portion 34 that rises from approximately the center of top plate 33, and a generally cylindrical third wall portion 31 that rises from top plate 33 outside stopper portion 34.
[0027] Second wall portion 30 is cylindrical, and has a rectangular notch 30a that reaches the bottom end at a portion continuous with hinge 23 and spring 24. This notch 30a is provided to avoid interference between lid portion 25 and support portion 22. When lid portion 25 is closed, this notch 30a is adjacent to or abuts against arc-shaped peripheral wall 22c of base portion 14, so that peripheral wall 22c and second wall portion 30 are flush with each other as described above.
[0028] In addition, the portion of the second wall portion 30 opposite the hinge 23 has a flat surface 30b or a concave surface (see symbol 30c in Figure 4) so that the user can easily hook their fingers, and a part of the top plate 33 protrudes to form a knob 30d.
[0029] The tube container 10 configured in this manner can be used in the same way as a conventional tube container with a hinge cap. That is, when the container body 11 is not in use, the top plate 33 is placed on a table T or the like with the hinge cap 12 facing downwards as shown in FIG. 2B. The reason why the center of the top surface of the top plate 33 is slightly recessed (see FIG. 2B) is that the peripheral edge of the top plate 33 comes into contact with the table T or the like when placed in this manner, thereby stabilizing the container. The product name and description displayed on the body 15 are displayed in this orientation.
[0030] Furthermore, when the tube container 10 is placed upside down as shown in FIG. 2B , moisture may enter the space of the support portion 22 of the base portion 14. To allow this moisture to drain to the outside while the tube container 10 remains in the state shown in FIG. 2B , a water passage hole 22d may be provided in the upper wall 22b of the support portion 22, and a drain hole 33a may be provided in the top plate 33 of the lid portion 25. The water passage hole 22d transfers moisture that has entered the inside of the support portion 22 into the space of the lid portion 25, and the drain hole 33a drains this moisture to the outside. The drain hole 33a also drains moisture that has entered the space of the lid portion 25 outside the support portion 22 to the outside.
[0031] Furthermore, the upper wall 22b and the top plate 33 may each have an inclined surface on the inner side thereof that slopes downward toward the drain hole 33a or the water passage hole 22d when the tube container 10 is inverted. In this case, moisture can easily flow toward the water passage hole 22d and the drain hole 33a. However, the water passage hole 22d and the drain hole 33a are not necessarily provided. In the tube container 10 shown in FIG. 2B, the upper wall 22b slopes downward toward the water passage hole 22d, allowing moisture in the support portion 22 to flow from the water passage hole 22d to the lid portion 25. Furthermore, the inner surface of the top plate 33 may have a slight slope, as indicated by the dashed line p in FIG. 2B, relative to the horizontal line indicated by the solid line. In this case, the inner side of the top plate 33 slopes downward toward the drain hole 33a, allowing moisture in the lid portion 25 to flow from the drain hole 33a to the outside.
[0032] When using the tube container 10, as shown in FIG. 1, the hinge cap 12 is turned upward, and the closed lid portion 25 (two-dot chain line CL) is rotated around the hinge 23 with a finger by placing a finger on the knob 30d of the lid portion 25, which then opens as shown by the solid line and the two-dot chain line OP. This causes the stopper portion 34 to come out of the discharge outlet 29 as shown in FIG. 3A. In this state, the contents can be pushed out of the discharge outlet 29 by squeezing the body portion 15. After removing the contents, the lid portion 25 is rotated counterclockwise in FIG. 1 to return it to the closed state (two-dot chain line CL), and the container is placed on a table T or the like with the lid portion 25 facing downward.
[0033] Although this tube container 10 does not have a shoulder cover on the base portion 14, as shown in FIG. 2B , the shoulder portion 16 is covered by the second wall portion 30 of the lid portion 25 when the lid is closed, thereby maintaining its appearance and self-standing ability. Furthermore, since there is no shoulder cover, the shoulder portion 16 can be touched with the fingers when the lid is opened. This makes it easier to touch the upper portion 15c of the body portion 15 against the underside of the shoulder portion 16 when there is little content remaining, facilitating the removal of the remaining content. Furthermore, since the base portion is smaller than the lid portion, the overall amount of material required for the cap can be reduced. Furthermore, since the first wall portion 21 of the base portion 14 can be formed to a size corresponding to the connecting portion 13, if the body portion 15 and the lid portion 25 have large sizes (outer diameters), the shoulder portion 16 exposed outside the base portion 14 when the lid is open can be made larger. For example, the outer diameter of the body portion 15 may be approximately 50 mm, and the radial length of the shoulder portion 16 exposed outside the base portion 14 when the lid is open may be approximately 10 to 11 mm at most.
[0034] Furthermore, the third wall portion 31 engages with the mating step portion 32 of the base portion 14, so that the lid portion 25 is firmly connected to the base portion 14. The top plate 33 of the lid portion 25 is also wide, so that the inverted tube container 10 can remain stable and upright even when it contains a considerable amount of contents.
[0035] 2B, when the lid is closed, a closed annular space is formed by the third wall portion 31 and the stopper portion 34, so that the contents remaining around the discharge port 29 can be kept within this space, thereby preventing the outside from becoming soiled.
[0036] It is preferable that the thickness of the shoulder portion 16 is thicker than the thickness of the body portion, which prevents deformation of the shoulder portion 16 when a finger touches the shoulder portion 16 to remove contents remaining near the shoulder portion 16. This prevents the second wall portion 30 from interfering with the shoulder portion 16 when the lid is closed, and prevents the gap S between the second wall portion 30 and the shoulder portion 16 from widening.
[0037] Furthermore, the axial length of the second wall portion 30 can be made shorter than in a configuration in which the shoulder portion 16 protrudes axially upward beyond the end of the body portion 15. This reduces the amount of material used for the hinge cap. Furthermore, this tube container 10 has a transition portion 17 around the shoulder portion 16, making it even easier to remove contents remaining near the shoulder portion.
[0038] Furthermore, the gap S provided by the step portion 17a functions to prevent interference between the lid portion 25 and the shoulder portion 16 when the lid is closed. This gap S is concealed by the transition portion 17, which is connected axially above the shoulder portion 16, thereby maintaining a desirable appearance. In FIG. 2B, the axial dimension d of the gap S and the step portion 17a is similar. However, the gap S may be smaller or larger than the dimension d. Furthermore, when comparing the resistance to deformation of the outer periphery of the shoulder portion 16 with and without the step portion 17a under the same conditions for the thicknesses of the shoulder portion 16 and the transition portion 17, the presence of the step portion 17a makes the outer periphery of the shoulder 16 less likely to deform. Therefore, the appearance is maintained and the closed state can be stabilized until the contents are consumed.
[0039] The second wall 30 provided on the outer periphery of the lid 25 is positioned inside the step 17a when the lid is closed, making the gap S between the end of the second wall 30 and the shoulder 16 less noticeable and maintaining an excellent appearance. The third wall 31 provided on the inner periphery of the lid 25 abuts against the base 14 to support the top plate 33 when the lid is closed, thereby suppressing damage to the lid 25. In addition, the position of the lid 25 relative to the container body 11 is fixed when the lid is closed. Therefore, the inverted state of the tube container 10 is stably maintained.
[0040] The tube container 10A in Figures 4A and 4B and the hinge cap 12A in Figure 5 are substantially similar to the tube container 10 in Figures 1 and 2 and the hinge caps in Figures 3A to 3C, with only slight differences in the shapes of the engaging portion 26 of the lid portion 25 and the support portion 22. That is, in the hinge cap 12 in Figures 4A and 4B, the upper surface of the engaging portion 26 is tapered, which allows the synthetic resin to flow in smoothly. However, when the lid is closed, the closed annular space formed by the third wall portion 31 and the stopper portion 34 is narrow.
[0041] 1, the upper wall 22b of the support portion 22 of the hinge cap 12 is an inclined surface that gradually slopes downward toward the outside. On the other hand, in the hinge cap 12A of FIGS. 4A and 4B, the upper wall 22b of the support portion 22 is approximately horizontal. Due to this difference, the position of the hinge 23 in FIG. 1 is lower than the position of the hinge 23 in FIGS. 4A and 4B. As a result, the position of the second wall portion 30 in FIG. 1 relative to the discharge port 29 when the lid is open can be lower than the position of the second wall portion 30 in FIGS. 4A and 4B. Therefore, it is easier to discharge the contents of the tube container 10 in FIG. 1 than the tube container 10A in FIG. 4.
[0042] 4A and 4B, a square bar-shaped stopper portion 35 is provided between the first wall portion 21 and the upper wall 22b of the support portion 22, as shown in Fig. 5. Furthermore, an enlarged ring portion 36 is provided at the lower end of the first wall portion 21, and a square bar-shaped stopper portion 37 is also provided between the lower portion of the first wall portion 21 and the ring portion 36. The stopper portions 35 and 37 engage with a stopper locking portion (not shown) of the container body 11 when the hinge cap 12A and the container body 11 are completely screwed together. Therefore, the hinge cap 12A is aligned with the container body 11 in the circumferential direction.
[0043] The hinge cap 12B shown in FIG. 6 has a recess 33b that extends from the periphery of the drain hole 33a to the periphery of the top plate 33 and is slightly recessed from the surface of the top plate 33. In this case, the drain hole 33a is not blocked by the table (designated by symbol T in FIG. 2b) on which the tube container is placed. Therefore, moisture that flows out from the drain hole 33a easily flows outward from the placement surface of the top plate 33. The drain holes 33a are provided on both the near side and the far side of the hinge 23. In this way, multiple drain holes 33a may be provided, and multiple water vent holes 22d may also be provided. However, the water vent holes 22d and the drain hole 33a are not necessarily provided.
[0044] While preferred embodiments have been described above with reference to the drawings, the present invention is not limited to these embodiments and includes various modifications within the spirit and scope of the invention. For example, while the hinge cap is screwed to the connecting portion of the container body in the above-described embodiment, it may be elastically snap-fitted between a ridge and a mating recess, or may be integrally joined by adhesive or thermal welding. While a spring is provided in addition to the hinge in the above-described embodiment, the spring may be omitted. Furthermore, while the container body 11 and hinge caps 12, 12A, and 12B in the above-described embodiment have a circular cross-sectional shape, they may also have an oval or other oblong shape, or a square, rectangular, or other rectangular shape.
