Description

[Technical field]

[0001] The present invention relates to a cap. [Background technology]

[0002] A cap as described in Patent Document 1 below has been conventionally known. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2016-088536 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the conventional cap, when the container body is squeezed to pour the contents from the spout, if the container body is squeezed too hard, the flow of the contents may be disturbed and the contents may be forcefully poured out of the spout. At this time, the disturbed flow of the contents may cause the contents to be poured in an unintended direction.

[0005] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to make it easier to pour the contents in a desired direction. [Means for solving the problem]

[0006] <1> A cap according to one aspect of the present invention includes a cap body having a top, which is attached to the mouth of a container body in which contents are stored and has a top wall formed with a pouring outlet for pouring out the contents; a bottomed, cylindrical flow straightening tube extending downward from the top wall, the interior of which is connected to the pouring outlet and has a lateral hole formed in a peripheral wall; a hanging tube arranged next to the straightening tube in a first direction in which the horizontal hole opens from the straightening tube, extending downward from the top wall, and having an interior that communicates with the horizontal hole; Equipped with The hanging tube has a larger diameter than the straightening tube, a portion of the hanging tube located in the opposite direction to the first direction is integral with the straightening tube, the horizontal hole opens into the hanging tube, the hanging tube opens downward, and the hanging tube is provided with a notch that opens in the first direction. . <2> A cap according to one embodiment of the present invention comprises a topped, cylindrical cap body which is attached to the mouth of a container body in which contents are contained and has a pouring outlet formed in its top wall for pouring the contents; a bottomed, cylindrical straightening tube which extends downward from the top wall, the interior of which communicates with the pouring outlet and has a side hole formed in its peripheral wall; and a hanging tube which is arranged in line with the straightening tube in a first direction in which the side hole opens from the straightening tube and extends downward from the top wall, the interior of which communicates with the side hole, wherein the hanging tube is provided with a notch which opens in the first direction, and when viewed from the side of the hanging tube, the peripheral edge of the notch in the hanging tube is an arc-shaped tube that protrudes upward. <3> A cap according to one embodiment of the present invention comprises a topped, cylindrical cap body which is attached to the mouth of a container body in which contents are contained and has a pouring outlet formed in the top wall for pouring the contents; a bottomed, cylindrical straightening tube which extends downward from the top wall, the interior of which is connected to the pouring outlet and has a side hole formed in the peripheral wall; a valve member which is positioned below the top wall and switches between communication between the interior of the container body and the side hole and blocking communication therebetween; and a mounting tube which extends downward from the top wall and has the straightening tube disposed inside it and to which the valve member is attached, the peripheral wall of the cap body comprising an inner ring which surrounds the mounting tube from the radial outside and which is fitted into the mouth, and the valve member further comprises a sealing piece which blocks the space between the mounting tube and the inner ring. <4> the above <1> or <2> In the cap according to the above, a configuration may be adopted in which the cap further comprises a valve member disposed below the top wall for switching between communication between the inside of the container body and the lateral hole and blocking the communication therebetween. <5> the above <3> In the cap according to the above, a configuration may be adopted in which a hanging tube is arranged next to the straightening tube in a first direction in which the lateral hole opens from the straightening tube, extends downward from the top wall, and has an interior that communicates with the lateral hole.

[0007] For example, when the container body is squeezed, the contents in the container body pass through the side hole of the straightening cylinder and the inside of the straightening cylinder to reach the spout, and then are poured out from the spout. During this process, the contents pass through the side hole of the straightening cylinder, so that they flow in a direction that crosses the vertical direction once, but then pass through the inside of the straightening cylinder, so that the flow is straightened in the vertical direction. Therefore, even if the container body is squeezed strongly, for example, the flow of the contents is prevented from being disturbed. This makes it easier to pour the contents in the desired direction. the above <1> , <2> , <5> In the cap according to the above, for example, when the container body is squeezed and deformed, the contents in the container body pass through the hanging tube before reaching the horizontal hole of the flow straightening tube, thereby further suppressing the disturbance of the flow of the contents. the above <2> In the cap according to the above, the periphery of the notch in the hanging tube is an arcuate shape that protrudes upward when viewed from the side of the hanging tube. Therefore, even if the contents in the container body are foamed, the foam can be removed by the periphery of the notch in the hanging tube when the contents pass through the notch. the above <3> , <4> In the cap according to the present invention, the valve member switches between communication between the inside of the container body and the lateral hole and blocking the communication. This makes it possible to prevent the content from being accidentally discharged. When the cap is provided with a valve member, the valve member may cause the content to foam. In this case, the cap may be provided with a hanging tube as described above to prevent the content from foaming. When the cap is provided with a valve member, the contents are more difficult to pour out of the cap than when the cap is not provided with a valve member, and the amount of contents remaining in the container body may increase. Also, when tilting the container body to pour out the contents, if the contents flow into the space between the mounting tube and the inner ring, the amount of contents remaining may further increase. <3> In the cap according to the present invention, the valve member is provided with a sealing piece that closes the space between the mounting tube and the inner ring. This prevents the contents from flowing into the space between the mounting tube and the inner ring when the container body is tilted to pour out the contents. As a result, the amount of contents remaining in the container body can be reduced.

[0008] < 6 >Above <1> from <5> Any one of the following In the cap according to the present invention, when the lateral hole is viewed from the front, The connector may be formed by two vertical sides extending in the vertical direction, an upper horizontal side connecting the upper ends of the two vertical sides, and a lower connecting portion connecting the lower ends of the two vertical sides, and the corners formed between each of the two vertical sides and the upper horizontal side may be curved. < 7 >Above< 6 >In the cap related to the above, the front view shape of the horizontal hole may be rectangular formed by the two vertical sides, the upper horizontal side, and a lower horizontal side as the lower connecting part.

[0009] The corners formed between each of the two vertical sides and the upper horizontal side are curved. This makes it possible to effectively prevent the flow of the contents from being disturbed when the contents pass through the horizontal hole. For example, if the corners are formed by the intersection of the vertical sides and the horizontal sides, there is a risk that the contents will unintentionally spread from the spout in the direction in which the horizontal sides extend when the contents pass through the spout.

[0010] < 8 >Above <1> From < 7 In the cap according to any one of the above items, a configuration may be adopted in which a flow path cross-sectional area of ​​the spout is equal to or larger than a flow path cross-sectional area of ​​the lateral hole.

[0011] The flow path cross-sectional area of ​​the spout is equal to or larger than the flow path cross-sectional area of ​​the side hole, and the flow path cross-sectional area of ​​the side hole is smaller. This significantly improves the effect of regulating the flow of the contents by passing through the side hole.

[0016] < 9 >Above <1> From < 8 > In the cap according to any one of the above items, the upper surface of the bottom wall of the straightening tube may be configured to slope downward as it moves from the opposite side of the lateral hole toward the lateral hole, across the axis of the straightening tube.

[0017] The upper surface of the bottom wall of the flow straightening cylinder is inclined downward from the opposite side of the horizontal hole to the horizontal hole side, across the axis of the flow straightening cylinder, thereby preventing the contents from accumulating inside the flow straightening cylinder after they have been poured out. Effect of the Invention

[0022] According to the present invention, it is possible to easily pour out the contents in a desired direction. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] (First embodiment) A cap 50 according to a first embodiment of the present invention will now be described with reference to FIGS. The cap 50 is attached to the mouth 1 of the container body A. The container body A contains the contents (content liquid). The container body A is preferably deformable by squeezing. The container body A has the mouth 1 at the top. An engagement ridge 2 is provided on the upper part of the outer periphery of the mouth 1. The upper part of the outer periphery of the engagement ridge 2 forms an inclined surface 2a.

[0025] The cap 50 includes a cap body B having a cylindrical shape with a top, a lid body D having a cylindrical shape with a top, a flow straightening cylinder 80 having a cylindrical shape with a bottom, and a hanging cylinder 90. The lid body D is attached to the cap body B via a hinge C so as to be able to open and close. In this embodiment, the cap 50 is a so-called hinge cap.

[0026] In the following, the central axis of the cap body B is referred to as the cap axis O. The direction of the cap axis O is referred to as the up-down direction. The side of the lid body D relative to the cap body B along the up-down direction is referred to as the upper side, and the side of the cap body B relative to the lid body D is referred to as the lower side. The direction perpendicular to the cap axis O is referred to as the radial direction. Along the radial direction, the side where the hinge C is located relative to the cap axis O is referred to as the back side (rear side), and the opposite side of the hinge C relative to the cap axis O is referred to as the pouring side (front side). The direction going around the cap axis O is referred to as the circumferential direction. The clockwise side along the circumferential direction when viewed from above of the cap body B is referred to simply as the clockwise side. The counterclockwise side along the circumferential direction when viewed from above of the cap body B is referred to simply as the counterclockwise side.

[0027] As shown in Figures 1 and 2, the cap body B comprises a peripheral wall 3 (mounting portion) that is fitted into the mouth portion 1 of the container body A, a top wall 4 (upper wall) that extends inward from the inner edge of the peripheral wall 3 and seals the opening of the mouth portion 1, a pouring outlet 4a that penetrates the top wall 4, and a pouring tube 5 that is erected on the upper surface of the top wall 4 with a diameter slightly wider than the pouring outlet 4a.

[0028] The peripheral wall 3 is a double cylindrical wall. The peripheral wall 3 includes an annular lid engaging portion 6 that engages with the lid body D, an inner cylinder 7 that is provided vertically from the inner peripheral side of the lid engaging portion 6, and an outer peripheral wall portion 8 that is provided vertically from the outer peripheral side of the lid engaging portion 6. A hinge C is provided continuously to the upper end of the portion of the outer peripheral wall 8 located on the rear side. An engaging protrusion 9 that engages with the fitting protrusion 2 is provided on the lower inner periphery of the outer peripheral wall 8.

[0029] As shown in Fig. 2, the upper portion of outer peripheral wall 8 on the pouring side is provided with a stepped recess 15 recessed from the outer periphery in an arc shape over a range of approximately 180° around the cap axis. The upper surface 8a of the remaining portion of the upper portion of outer peripheral wall 8 (the portion on the rear side) is flush with the upper surface of top wall 4. A hinge C is connected to the upper end of the outer periphery of the remaining portion. The step recess 15 is formed by a flat surface 15a that is recessed a distance α from the top surface 8a, an inclined surface 15b that slopes radially inward and upward from the inner peripheral edge of the flat surface 15a, and an inclined side surface 15c that extends circumferentially from the peripheral end of the flat surface 15a and slopes upward toward the top surface 8a.

[0030] The lid engaging portion 6 has a circular lid engaging protrusion 11 standing thereon. The lid engaging protrusion 11 has a locking protrusion 13 formed on its outer periphery. The structure connecting the inner tube 7 and the outer peripheral wall portion 8 is not limited to the lid engaging portion 6. For example, this structure may be a ring-shaped base wall portion. In this case, the lid engaging portion 6 may be provided on the peripheral portion of the top wall 4, for example.

[0031] As shown in FIG. 2, an outer peripheral cut 16 having a generally V-shape in plan view is provided on the outer peripheral surface at a portion located near the clockwise side of the hinge C of the outer peripheral wall 8. The outer peripheral cut 16 is cut downward from the upper surface 8a, leaving a thin bottom wall at the lower end of the outer peripheral wall 8. An inner peripheral cut (not shown) is carved vertically at a position on the inner circumference of the outer peripheral wall 8 corresponding to the outer peripheral cut 16. This makes this position thin by being cut from inside and outside. This position forms a vertical weakened portion 17 that forms a vertical tear line.

[0032] A slit groove 18 is recessed downward in a portion of the upper surface 8a of the outer peripheral wall portion 8 located on the rear side closer to the hinge C (counterclockwise side) than the outer peripheral cut portion 16. The slit groove 18 extends in the circumferential direction (counterclockwise side) from an upper portion on the inner peripheral side (diametrically inner side) of the counterclockwise end face 16a of the outer peripheral cut portion 16. The slit groove 18 extends to the step recess 15. The step recess 15 is located at the counterclockwise end of the upper surface 8a. The portion of the upper surface 8a of the outer peripheral wall portion 8 located on the opposite side (clockwise side) of the hinge C from the outer peripheral cut portion 16 is a thick portion 19 where the upper portion of the outer peripheral wall portion 8 and the lower portion of the lid engagement portion 6 are integrally connected.

[0033] As shown in Figures 5 to 8, the bottom surface 20 of the slit groove 18 is recessed deepest from the top surface 8a by a distance β from the end surface 16a to the center of the hinge C (cross section shown in Figure 5), with the bottom surface 20a. The bottom surface 20 becomes bottom surfaces 20b and 20c at approximately 45° (cross section shown in Figure 6) and 60° (cross section shown in Figure 7) from the center of the hinge C counterclockwise, respectively, and the height from the top surface 8a gradually becomes shallower from the distance β. Finally, the inclined side surface 15c of the step recess 15 is cut out at approximately 90° (cross section shown in Figure 8) from the center of the hinge C counterclockwise, and continues to the end of the flat surface 15a at a distance α.

[0034] The inner circumferential side of the bottom surface 20, from the end face 16a side to the center of the hinge C as shown in Fig. 5, becomes a thin-walled lower lateral weakened portion 21 that connects the outer circumferential wall portion 8 to the lower wall portion of the lid engagement portion 6. The inner circumferential side of the bottom surface 20, from the center of the hinge C to approximately 90° as shown in Figs. 6 to 8, becomes an arc-shaped connecting portion 22 that slopes radially inward and upward from the upwardly sloping inner circumferential edge of the bottom surface 20. 5 to 8, a portion located radially outward from the slit groove 18 on the rear side of the outer peripheral wall portion 8 constitutes a rear outer wall portion 23 standing upright from the bottom surface 20 to the upper surface 8a of the slit groove 18. A hinge C is connected to a predetermined position on the upper end of the outer periphery of the rear outer wall portion 23.

[0035] As shown in Figure 5, at the upper part of the inner circumference of the part of the outer wall portion 8 located in the center of the back side, an abutment surface portion 24 is formed which slopes radially inward and upward from above the lower lateral weakened portion 21 and abuts against the inclined surface 2a of the mating protrusion 2 when attached to the container body A. 6 and 7, a parallel surface 25 that slopes inward and upward in parallel with the outer surface of the outer connecting portion 22 is provided above the height of the inclined bottom surface 20 on the upper part of the inner circumference of the portion of the outer peripheral wall portion 8 that is located counterclockwise from the center of the back side. The parallel surface 25 is formed so as to be separated from the inclined surface 2a of the fitting protrusion 2 when the container body A is attached. The portion between the parallel surface 25 and the outer surface of the connecting portion 22 is thinned to form an inclined connection weakening portion 26.

[0036] As shown in Fig. 8, in the portion of the outer peripheral wall 8 located on the pouring side (the range of the step recess 15), an upward recess 27 is recessed from below into the outer peripheral edge of the lower surface of the lid engagement part 6. The area between the upward recess 27 and the inclined surface 15b of the step recess 15 is thinned to form an upper lateral weakened part 28. The lower lateral weakened portion 21, the inclined connecting weakened portion 26 and the upper lateral weakened portion 28 are formed in sequence and continuous to each other, forming a circumferential tear line.

[0037] The spout 4a is shifted in the radial direction with respect to the cap axis O. In this embodiment, the spout 4a is shifted toward the spouting side with respect to the cap axis O. The spout 4a is a hole formed in the top wall 4. The portion of the pouring tube 5 located on the pouring side is higher than the portion located on the back side (hinge C side). This makes it easier to pour the contents. A lip portion 5a is provided at the upper end of the pouring tube 5. The lip portion 5a is flared in a trumpet shape. In addition, the portion of the inner surface of the spout 4a located on the back side and the portion of the inner surface of the spout tube 5 located on the back side are located on the same straight line (hereinafter also referred to as the first straight line) parallel to the cap axis O when viewed in a vertical cross section along the cap axis O.

[0038] 1, the flow straightening cylinder 80 extends downward from the top wall 4. The inside of the flow straightening cylinder 80 communicates with the pouring outlet 4a. The flow straightening cylinder 80 is disposed coaxially with the pouring outlet 4a. An upper surface 83a of the bottom wall 83 of the flow straightening cylinder 80 is inclined downward from the opposite side of the horizontal hole 82 toward the horizontal hole 82 side, across the axis of the flow straightening cylinder 80. The upper surface 83a of the bottom wall 83 is an inclined surface that is inclined downward from the pouring side toward the back side.

[0039] A horizontal hole 82 is formed in the peripheral wall 81 of the straightening tube 80. The horizontal hole 82 penetrates the peripheral wall 81. The horizontal hole 82 opens from the straightening tube 80 towards the rear side. The rear side is the direction in which the horizontal hole 82 opens from the straightening tube 80 (first direction). The horizontal hole 82 is arranged over the entire length of the peripheral wall 81 in the up-down direction. A portion of the lower edge of the horizontal hole 82 located on the pouring side is continuous with an upper surface 83a of the bottom wall 83 of the straightening tube 80. A portion of the lower edge of the horizontal hole 82 located on the rear side is located on the first straight line in the vertical cross-sectional view described above.

[0040] As shown in FIG. 4, the shape of the horizontal hole 82 in front view is rectangular. The shape of the horizontal hole 82 in front view is the shape of the horizontal hole 82 when viewed from the direction in which the horizontal hole 82 opens. The rectangular shape of the horizontal hole 82 in front view is formed by two vertical sides 82a extending in the up-down direction, an upper horizontal side 82b connecting the upper ends of the two vertical sides 82a, and a lower horizontal side 82c (connecting portion) connecting the lower ends of the two vertical sides 82a. An angle 82d formed between each of the two vertical sides 82a and the upper horizontal side 82b is curved. In the illustrated example, an angle 82e formed between each of the two vertical sides 82a and the lower horizontal side 82c is an angular shape formed by the intersection of the vertical side 82a and the horizontal side 82c.

[0041] The flow passage cross-sectional area of ​​the spout 4a is equal to or larger than the flow passage cross-sectional area of ​​the side hole 82. The shape of the spout 4a in a front view is, for example, circular. The diameter of the spout 4a is, for example, 3 mm. The flow passage cross-sectional area of ​​the spout 4a is, for example, about 7 mm. 2 (π×1.5 2 The height of the side hole 82 is, for example, 1 mm to 5 mm, preferably 2 mm. The width of the side hole 82 is, for example, 1 mm to 3 mm, preferably 2.5 mm. The flow passage cross-sectional area of ​​the side hole 82 is, for example, about 5 mm. 2 (2mm x 2.5mm).

[0042] The hanging tube 90 is arranged next to the back side of the flow straightening tube 80. The hanging tube 90 extends downward from the top wall 4. The hanging tube 90 has a larger diameter than the flow straightening tube 80. The axis of the hanging tube 90 is arranged on the pouring side with respect to the cap axis O. The axis of the flow straightening tube 80, the axis of the hanging tube 90, and the cap axis O are arranged on the same straight line. The vertical size of the hanging tube 90 is larger than the vertical size of the flow straightening tube 80. The lower end of the hanging tube 90 is located lower than the lower end of the flow straightening tube 80.

[0043] The interior of the hanging tube 90 communicates with the horizontal hole 82. A portion of the hanging tube 90 located on the pouring side is integral with the flow straightening tube 80. The horizontal hole 82 opens into the hanging tube 90. The portion of the inner circumferential surface of the hanging tube 90 located on the pouring side is located on the first straight line in the vertical cross-sectional view. The hanging tube 90 does not have a bottom. The hanging tube 90 opens downward. The hanging tube 90 is provided with a notch 91 that opens to the rear side. The notch 91 is formed over half the circumference of the rear side of the hanging tube 90. The notch 91 cuts out the lower end of the hanging tube 90. The notch 91 becomes larger in the vertical direction from the pouring side toward the rear side. At the end of the hanging tube 90 on the rear side, the notch 91 extends over the entire length of the hanging tube 90 in the vertical direction.

[0044] In a side view of the hanging tube 90, the peripheral edge 91a of the notch 91 in the hanging tube 90 is an arc shape that protrudes upward and toward the pouring side. Viewing the side of the hanging tube 90 is viewing the hanging tube 90 from the left-right direction. The left-right direction is a direction perpendicular to the up-down direction and the front-rear direction. The front-rear direction is a direction perpendicular to the cap axis O and passing through the center of the hinge C.

[0045] The lid body D is rotatably attached to the upper end of the outer periphery of the outer periphery wall portion 8 of the cap body B via a hinge C. The lid body D includes a top wall 30, a side peripheral wall 31 suspended from the periphery of the top wall 30, and a sealing tube 32 suspended from the back surface of the top wall 30 and inserted into the inner periphery of the pouring tube 5 when the lid is closed to seal the pouring tube 5. A deformable thin-walled portion 33 is provided around the top wall 30 at a portion located on the outer circumferential side of the sealing cylinder 32. As shown in FIG.

[0046] As shown in FIG. 1, an engagement recess 35 is provided around the inner periphery of the lower end of the side peripheral wall 31 to engage with the lid engagement protrusion 11 of the lid engagement portion 6 to maintain the lid in the closed state. An inward surface of the engagement recess 35 is provided with an engagement portion 36 that engages with the engagement ridge 13 of the lid engagement projection 11. A downward surface of the engagement recess 35 abuts against the upper surface of the lid engagement projection 11.

[0047] As shown in Fig. 2, the side wall 31, except for the central portion on the pouring side and the central portion on the back side, is provided with a plurality of locking projections 37 that come into contact with the upper inner periphery of the lid engaging projection 11 when the lid is closed to prevent the side wall 31 from spreading outward. A knob 38 having an arc shape is formed in the circumferential direction on the outer periphery of the side wall 31 at the lower portion on the pouring side. A hinge C is connected to the lower end of the outer periphery of the side wall 31 on the back side. 1, an arc-shaped covering wall 39 is vertically attached to the outer periphery of the lower surface of the side peripheral wall 31 at the portion located on the pouring side so as to cover the stepped recess 15 of the outer periphery wall portion 8 of the cap body B when the cap is closed. The lower end of the covering wall 39 is close to or abuts against the flat surface 15a of the stepped recess 15.

[0048] Next, the manner of use and the effects of this embodiment will be described. The cap 50 of this embodiment is first integrally molded in the state shown in Fig. 2, and then the lid body D is rotated via the hinge C to cover the cap body B and close the lid as shown in Fig. 1. At this time, the outer peripheral surface of the lower part of the sealing tube 32 of the lid body D is in close contact with the inner peripheral surface of the lower part of the pouring tube 5 of the cap body B. Also, the engagement recess 35 of the side peripheral wall 31 of the lid body D and the lid engagement protrusion 11 of the lid engagement portion 6 of the cap body B are engaged with each other to maintain the lid closed.

[0049] Next, as shown in FIG. 1, the closed cap 50 is attached to the mouth portion 1 of the container body A filled with the contents. In the capping process, the mouth 1 of the container body A is placed in the annular groove formed between the inner tube 7 and the outer peripheral wall 8 of the peripheral wall 3. When a pressing force is applied from above to the lid D, the engaging protrusion 9 of the outer peripheral wall 8 overcomes the mating ridge 2 of the mouth 1 and engages with it. The mouth 1 of the container body A is clamped between the outer periphery of the inner tube 7, the inner periphery of the outer peripheral wall 8, and the lid engaging portion 6, and thus the cap 50 is attached to the container body A.

[0050] When the container body A filled with hot contents is capped, the pressure inside the container body A rises. Here, since the top wall 30 has a deformable thin-walled portion 33 formed on the outside of the sealing tube 32, only the inner peripheral side of the thin-walled portion 33 of the top wall 30 rises, releasing the pressure to the outside of the pouring tube 5. This allows the engagement between the engagement recess 35 of the side peripheral wall 31 of the lid body D and the lid engagement portion 6 of the cap body B to be unimpeded, and the lid is maintained closed. This prevents the lid body D from opening due to an increase in internal pressure when the contents are hot.

[0051] In addition, even if an impact force is applied to the top wall 30 of the lid body D when the cap 50 falls upside down in the closed state, the thin-walled portion 33 absorbs the impact received by the lid body D and the sealing tube 32 is not pushed into or pulled away from the pouring tube 5. This does not affect the tight contact between the sealing tube 32 and the pouring tube 5 of the cap body B, and prevents the sealing tube 32 and the pouring tube 5 from coming loose and from damaging each other.

[0052] When using the contents in the container body A, by hooking the fingers on the knob portion 38 of the lid body D and lifting it, the seal between the sealing tube 32 of the lid body D and the pouring tube 5 of the cap body B is released and the engagement between the side wall 31 of the lid body D and the lid engagement portion 6 of the cap body B is released, and the lid body D is opened. When the container body A is squeezed and deformed with the lid body D open, the contents in the container body A pass through the inside of the hanging tube 90, the horizontal hole 82 of the straightening tube 80, and the inside of the straightening tube 80 to reach the pouring outlet 4a, and then pass through the pouring outlet 4a to be poured out of the pouring tube 5.

[0053] In the cap 50 of this embodiment, a covering wall 39 is provided on the outer peripheral edge of the pouring side of the underside of the side peripheral wall 31 of the lid body D. This makes it possible to hide the stepped recess 15 of the outer peripheral wall portion 8 of the cap body B when the lid is closed. Also, when opening the lid, fingers placed under the knob portion 38 hit the covering wall 39, preventing them from touching the inside of the lid body D. This keeps the inside of the cap 50 clean.

[0054] By closing the lid body D on the cap body B again, the outer periphery of the sealing tube 32 of the lid body D comes into close contact with the inner periphery of the pouring tube 5 of the cap body B to form a seal, thereby sealing the inside of the container body A. The cap 50 can be used by repeatedly opening and closing the lid body D.

[0055] The cap 50 of this embodiment is provided with a stepped recess 15 having a flat surface 15a and an inclined surface 15b on the pouring side of the outer peripheral wall 8 of the cap body B. Therefore, even if the contents drip from the lip 5a of the pouring tube 5 into the stepped recess 15 during use, the contents will flow to the flat surface 15a due to the inclination of the inclined surface 15b. In addition, since the flat surface 15a is a flat surface without any irregularities, dirt can be easily wiped off with tissue or the like.

[0056] Next, a mode in which the cap 50 is separately disposed of after the contents in the container body A have all been used will be described. In this case, when the cap 50 is opened and the lid body D is grasped with the fingers and pulled, for example, radially outward, the rear outer wall portion 23, which is the connecting portion with the hinge C of the outer peripheral wall portion 8, is pulled via the hinge C. As a result, the rear side of the outer peripheral wall portion 8 connected to the rear outer wall portion 23 is pulled and deformed. This causes the vertical weakened portion 17 formed by the outer peripheral cut portion 16 to break.

[0057] When the lid body D is pulled further, the lower horizontal weakened portion 21 is cut in the circumferential direction from the end face 16a side connected to the vertical weakened portion 17, and then the continuous inclined connection weakened portion 26 begins to break. As the breakage of the inclined connection weakened portion 26 progresses, the lower side of the broken outer peripheral wall portion 8, which is partitioned by the lower horizontal weakened portion 21 and the inclined connection weakened portion 26 of the lid body D and the cap body B connected thereto, is separated from the cap body B.

[0058] Next, when the inclined connection weakened portion 26 is completely broken, the continuous upper lateral weakened portion 28 is broken. This break passes through the step recess 15 and is stopped by the thick portion 19, for example. Furthermore, when the broken outer peripheral wall 8 is pulled, the thick portion 19 of the connected outer peripheral wall 8 is pulled, for example, radially outward, and the engagement between the engagement protrusion 9 of the outer peripheral wall 8 of the cap body B and the engagement protrusion 2 of the mouth 1 of the container body A is released. When the lid body D is raised upward as is, the upper side of the outer peripheral wall 8 connected by the thick portion 19 is lifted and the cap body B is removed from the mouth 1 of the container body A. This allows the cap 50 and the container body A to be disposed of separately.

[0059] In the cap 50 of this embodiment, when the inclined connection weakened portion 26 is cut, the inclined connection weakened portion 26 is inclined from bottom to top in accordance with the inclination of the bottom surface 20, so that the force pulling the lower portion of the outer peripheral wall portion 8 is directed upward and the force is easily applied. Also, the inner peripheral parallel surface 25 forming the inclined connection weakened portion 26 is separated from the inclined surface 2a of the fitting protrusion 2 of the container body A, so there is less resistance to cutting, making it easier to break. In addition, when cutting the upper horizontal weakened portion 28 on the pouring side, the upward recess 27 on the inner surface of the upper horizontal weakened portion 28 is completely separated from the inclined surface 2a of the mating protrusion 2 of the container body A, thereby further reducing the resistance to cutting and making it easier to break.

[0060] As described above, according to the cap 50 of this embodiment, when the container body A is squeezed and deformed with the lid body D open, the contents in the container body A pass through the inside of the hanging tube 90, the horizontal hole 82 of the straightening tube 80, and the inside of the straightening tube 80 to reach the spout 4a, and are then poured out from the spout 4a. In this process, the contents pass through the horizontal hole 82 of the straightening tube 80, flowing once in a direction intersecting the vertical direction, but then pass through the inside of the straightening tube 80 to straighten the flow in the vertical direction. Moreover, in this embodiment, the contents in the container body A pass through the hanging tube 90 before reaching the horizontal hole 82 of the straightening tube 80. Therefore, for example, even if the container body A is strongly squeezed and deformed, the flow of the contents is suppressed from being disturbed. Therefore, it is possible to easily pour out the contents in the desired direction.

[0061] The flow path cross-sectional area of ​​the spout 4a is equal to or larger than the flow path cross-sectional area of ​​the side hole 82, which is smaller. This significantly improves the effect of regulating the flow of the contents as they pass through the side hole 82. In a side view of the hanging tube 90, a peripheral edge 91a of the notch in the hanging tube 90 is an arc-shaped shape that protrudes upward. Therefore, even if the contents in the container body A are foamed, the foam can be removed by the peripheral edge 91a of the notch in the hanging tube 90 when the contents pass through the notch.

[0062] The corners 82d formed between each of the two vertical sides 82a and the upper horizontal side 82b are curved. This effectively prevents the flow of the contents from being disturbed when the contents pass through the horizontal hole 82. For example, if the corners 82d are angular shapes formed by the intersection of the vertical sides 82a and the horizontal side 82b, when the contents pass through the spout 4a, there is a risk that the contents will unintentionally spread from the spout 4a in the left-right direction, which is the direction in which the horizontal side 82b extends. An upper surface 8a of the bottom wall 83 of the flow straightening cylinder 80 is inclined, which prevents the contents from accumulating inside the flow straightening cylinder 80 after the contents are poured out.

[0063] Second embodiment Next, a cap according to a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and their description will be omitted, with only the differences being described.

[0064] 9, in cap 50A according to this embodiment, the lower end of the hanging tube 90 is located above the lower end of the inner tube 7 of the peripheral wall 3. In contrast to this, in cap 50 according to the first embodiment as shown in FIG. 1, the lower end of the hanging tube 90 is located below the lower end of the inner tube 7 (inner ring) of the peripheral wall 3. The inner tube 7 is fitted into the mouth portion 1.

[0065] In this embodiment, the cap 50A further includes a mounting cylinder 95 and a valve member 60.

[0066] The mounting tube 95 extends downward from the top wall 4 of the cap body B. The mounting tube 95 is integral with the top wall 4. The mounting tube 95 is eccentric toward the rear side with respect to the cap axis O. The flow straightening tube 80 and the hanging tube 90 are disposed inside the mounting tube 95. In this embodiment, a portion of the peripheral wall 81 of the flow straightening tube 80 located on the pouring side is integral with the mounting tube 95. The remaining portion of the flow straightening tube 80 other than the portion is disposed inside the mounting tube 95. The entirety of the hanging tube 90 is disposed inside the mounting tube 95.

[0067] The lower end of the mounting tube 95 is located lower than the lower end of the flow straightening tube 80 and the lower end of the hanging tube 90. The lower end of the mounting tube 95 is located higher than the lower end of the inner tube 7. The inner tube 7 surrounds the mounting tube 95 from the outside in the radial direction. An annular space S is formed between the mounting tube 95 and the inner tube 7. The space S opens downward.

[0068] The valve member 60 is attached to the mounting tube 95. The valve member 60 is disposed below the top wall 4. The valve member 60 switches between communication between the inside of the container body A and the lateral hole 82 and blocking it. The valve member 60 opens, for example, when the container body A is squeezed and deformed, causing the internal pressure of the container body A to increase. The valve member 60 opens, for example, when it receives pressure from the contents in the container body A.

[0069] The valve member 60 comprises a valve cylinder 61, a valve portion 62, and an outer cylinder 63. The valve cylinder 61 extends in the vertical direction. The upper end of the valve cylinder 61 is fitted into the interior of the mounting cylinder 95. The valve portion 62 is an elastically deformable membrane (elastic membrane). The valve portion 62 closes the interior of the valve cylinder 61. The outer cylinder 63 extends in the vertical direction. The outer cylinder 63 covers the mounting cylinder 95 from the outside in the radial direction. The outer cylinder 63 is disposed in the space S. The lower end of the outer cylinder 63 is connected to the center of the valve cylinder 61 in the vertical direction. It is noted that the outer cylinder 63 is not necessary.

[0070] 10, a slit 64 is formed in the valve portion 62. In this embodiment, the slit 64 is formed in a cross shape when viewed from above the valve portion 62. When pressure is applied to the valve member 60 from the outside, the peripheral portion of the slit 64 in the valve portion 62 elastically deforms, and the slit 64 widens, causing the valve member 60 to open.

[0071] In the illustrated example, the valve portion 62 is partially provided with a thick portion 65. The thick portion 65 is slightly thicker than other portions of the valve portion 62. For example, the thickness of the thick portion 65 is within twice that of the other portions. The thick portion 65 is provided at a position in the valve portion 62 corresponding to the slit 64. However, the thick portion 65 is not provided in the portion of the valve portion 62 where the end of the slit 64 is located. The thick portion 65 is a configuration for facilitating the formation of the slit 64 in the valve portion 62. The thick portion 65 may be omitted.

[0072] As described above, according to the cap 50A of this embodiment, the valve member 60 switches between communication and blocking between the inside of the container body A and the lateral hole 82. This makes it possible to prevent the content from being accidentally discharged. In addition, when cap 50A includes valve member 60, there is a risk that the contents may be easily foamed due to valve member 60. In this case, by providing cap 50A with the above-mentioned hanging tube 90 as in this embodiment, foaming of the contents can be suppressed.

[0073] Third embodiment Next, a cap according to a third embodiment of the present invention will be described with reference to FIGS. In the third embodiment, the same components as those in the second embodiment are denoted by the same reference numerals, and their description will be omitted, with only the differences being described.

[0074] 11, in a cap 50B according to this embodiment, a valve member 60B includes a seal piece 66 instead of an outer cylinder 63. That is, the valve member 60B includes a valve cylinder 61, a valve portion 62, and a seal piece 66. The seal piece 66 closes the space S. The seal piece 66 protrudes radially outward from the valve cylinder 61. The seal piece 66 is annular. The seal piece 66 closes the space S by abutting against the lower end of the inner cylinder 7.

[0075] The seal piece 66 includes a base 66a, an abutment portion 66b, and a connecting portion 66c. The base 66a is connected to the outer peripheral surface of the valve cylinder 61 at the center in the vertical direction. The base 66a extends in a direction perpendicular to the cap axis O. The abutment portion 66b extends radially outward from the outer edge of the base 66a. The abutment portion 66b extends downward as it moves radially outward. The upper surface of the abutment portion 66b abuts against the lower end of the inner cylinder 7. The connecting portion 66c connects the base 66a and the abutment portion 66b. The connecting portion 66c is thinner than the base 66a and the abutment portion 66b. As a result, the abutment portion 66b can be elastically deformed in the vertical direction starting from the connecting portion 66c.

[0076] When the cap 50B is provided with a valve member 60B as in this embodiment, it becomes more difficult for the contents to be poured out of the cap 50B compared to when the cap 50B does not have a valve member 60B, and there is a risk that the amount of contents remaining in the container body A will increase. Furthermore, when the container body A is tilted to pour out the contents, if the contents flow into the space S between the mounting cylinder 95 and the inner cylinder 7, there is a risk that the remaining amount of the contents will further increase. Therefore, in this cap 50B, the valve member 60B is provided with a sealing piece that closes the space S. This prevents the contents from flowing into the space S when the container body A is tilted to pour out the contents. As a result, the amount of contents remaining in the container body A can be reduced.

[0077] (Modifications of the second and third embodiments) Instead of the valve member 60 according to the second embodiment or the valve member 60B according to the third embodiment, it is also possible to employ valve members 60C, 60D, and 60E shown in Figures 13 to 15. The shapes of the slits 64 are different in each of these valve members 60C, 60D, and 60E. For example, as in a valve member 60C shown in FIG. 13, the slit 64 may be T-shaped. For example, as in a valve member 60D shown in FIG. 14, the slit 64 may be I-shaped. For example, a plurality of slits 64 may be arranged at intervals in the circumferential direction as in a valve member 60E shown in Fig. 15. In this valve member 60E, a portion of the valve portion 62 located between adjacent slits 64 in the circumferential direction functions as an elastic piece 67. As a result, the valve portion 62 acts as a so-called three-point valve.

[0078] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0079] For example, the notch, the hanging tube 90, the lid body D, and the pouring tube 5 may be omitted. The cap 50 may not be breakable when disposed of. The shape of the horizontal hole 82 in front view does not have to be rectangular. For example, the shape of the horizontal hole 82 in front view may be a square or an isosceles trapezoid. Furthermore, it may be a triangular shape that protrudes downward (in this case, the lower ends of the two vertical sides 82a are connected by a corner (connecting part) that protrudes downward). In addition, as long as the shape of the horizontal hole 82 in front view has a horizontal side 82b at the upper end of the horizontal hole 82 and the corners 82d at both ends of the horizontal side 82b are curved, the shape of the lower part of the horizontal hole 82 is not limited to the various angular shapes (rectangular, square, triangular) as described above. For example, the shape of the lower part of the horizontal hole 82 may be circular (elliptical, etc.). Furthermore, even if the shape of the horizontal hole 82 in a front view is any of these various shapes, the corners 82d formed between each of the two vertical sides 82a and the upper horizontal side 82b do not have to be curved. The cross-sectional area of ​​the flow passage of the spout 4a may be less than the cross-sectional area of ​​the flow passage of the lateral hole 82. The upper surface 8a of the bottom wall 83 of the flow straightening cylinder 80 does not have to be inclined. The cap 50 may be provided with a shrink label, a sealing member, or the like (not shown) between the cap body B and the lid body D to prevent unauthorized opening before use.

[0080] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
