DETAILED DESCRIPTION OF THE INVENTION

[0009] [Container 1, Liquid Product PR] FIG. 1 is a cross-sectional view of a liquid product PR according to one embodiment, showing a state in which the top lid 12 of the cap 10 is closed. The liquid product PR includes a container 1 and a liquid food contained in the container. The container 1 includes a container body 20 and a cap 10 attached to the container body 20. The container body 20 is not particularly limited, and may be, for example, a bottle made of a resin such as polyethylene (PE) or polyethylene terephthalate (PET), a so-called paper pack made of a paper material, or a glass bottle. An opening 21 is provided at the top of the container body 20, and the cap 10 is attached to the opening 21.

[0010] The liquid food may be, for example, edible oils and fats, and more specifically, edible oils and fats with a solid fat content of 5% or less at 20°C. Examples of edible oils and fats include vegetable oils such as rapeseed oil, soybean oil, sunflower oil, cottonseed oil, peanut oil, rice oil, corn oil, safflower oil, olive oil, kapok oil, sesame oil, evening primrose oil, linseed oil, and perilla oil, and synthetic oils and fats such as medium-chain fatty acid triglycerides. The liquid food may also be a seasoning or other liquid food. The following describes an example of a liquid food in which oil Lc is used. The solid fat content of edible oils and fats is measured according to the method described in AOCS Official Method Cd 16b-93.

[0011] [Cap 10] <Summary> Please refer to FIG. 2 in addition to FIG. 1. FIG. 2 is a cross-sectional view of a liquid product PR according to one embodiment, showing the top lid 12 of the cap 10 in an open state. The cap 10 can be attached to a container body 20 such as a PET bottle. The material of the cap 10 is not particularly limited, but may be, for example, a synthetic resin such as polyethylene, or a plant-derived material such as bio-PE (polyethylene) or bio-PP (polypropylene). In addition, in this embodiment, the cap 10 does not require a pull ring for unscrewing. Furthermore, the cap 10 of this embodiment is a so-called scoreless cap that does not have a pull ring or a score that is a rupturable thin-walled portion. Note that the cap 10 may also be a so-called pull-ringless cap that has a score but does not have a pull ring. The cap 10 includes a cap body 11, a top lid 12, and a pivoting part 13 that pivotally connects the top lid 12 to the cap body 11. The pivoting part 13 has, for example, a hinge structure and is capable of pivoting the top lid 12 around a pivot axis AX1. In each drawing, for ease of viewing, the cap body 11, the top cover 12, and the rotating portion 13 are shown with different hatchings, but they may be integrally molded.

[0012] <Cap body 11> The cap body 11 is attached to the opening 21 of the container body 20. The cap body 11 includes a spout 111 through which the grease Lc is poured, a peripheral wall 112 that forms a flow path for the grease Lc, and a bottom wall 113 that is connected to the peripheral wall 112 so as to close a lower end 112b of the peripheral wall 112. The cap body 11 also includes an outer tube 114 that is provided to surround the opening 21 of the container body 20, and an inner tube 115 that is provided to be positioned inside the opening 21. The cap body 11 also includes a top wall 116 that connects the upper end of the outer tube 114 to the upper end of the inner tube 115, a protrusion 117 formed on the top wall 116, and a connecting wall 118 that connects the top wall 116 to the peripheral wall 112.

[0013] (Spout 111) The spout 111 is a portion through which the grease Lc inside the container body 20 to which the cap body 11 is attached is poured out. In this embodiment, the spout 111 includes a lip portion 111a that extends outward around the entire periphery. The spout 111 may also have a lip portion that extends outward in a portion that includes the pouring direction D1 of the grease Lc.

[0014] (Peripheral wall 112) The peripheral wall 112 is connected to the spout 111 and forms a flow path FP for the grease Lc. In this embodiment, the peripheral wall 112 includes a step portion 112a. The step portion 112a causes the downstream side of the flow path FP to have a larger cross-sectional area than the upstream side of the flow path FP. However, the shape of the peripheral wall 112 and the flow path FP formed by the peripheral wall 112 can be changed as appropriate. For example, the cross-sectional area of ​​the flow path FP may be constant, or may gradually increase or decrease as it progresses downstream in the flow direction of the grease Lc.

[0015] (Bottom wall 113) The bottom wall 113 is connected to the lower end 112b of the peripheral wall 112 so as to close the lower end 112b. The bottom wall 113 is formed with a plurality of openings AP1 to AP3 through which the grease Lc in the container body 20 can pass. As a result, the grease Lc in the container body 20 is introduced into the flow path FP through the plurality of openings AP1 to AP3. At this time, the bottom wall 113 functions as a dispersion plate that suppresses pulsation while the grease Lc is being poured. That is, when the container body 20 is tilted, the bottom wall 113 prevents the grease Lc in the container body 20 from flowing into the flow path FP all at once. As a result, the exchange of the grease Lc with air in the container body 20 is stably performed, and pulsation when the grease Lc is poured is suppressed, thereby stabilizing the amount of grease Lc poured. Note that in this embodiment, the number of openings through which the grease Lc can pass is three, but the number of openings can be changed as appropriate.

[0016] Reference is now made to FIGS. 3 and 4. FIG. 3 is a plan view of the cap body 11. FIG. 4 is an explanatory diagram of the configuration of the bottom wall 113 of the cap body 11. In this embodiment, the openings AP1 to AP3 are formed in the annular region AR1 of the bottom wall 113, avoiding a predetermined region AR2 including the distal end DE, which is the farthest from the pivoting portion 13. This allows the cap 10 to pour at a deeper angle than when openings are formed in the predetermined region AR2 including the distal end DE. This can reduce dripping, particularly when a large amount of grease Lc remains in the container body 20. Reducing dripping improves the usability of the cap 10. For example, the predetermined region AR2 may be a region of the bottom wall 113 extending a predetermined distance Lde from the distal end DE toward the pivoting portion 13 (the opposite direction to the pouring direction D1). For example, the predetermined distance Lde may be equal to or greater than one-nth of the overall length L113 of the bottom wall 113 in the D1 direction. For example, n may be 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, or 15. Note that the predetermined area AR2 shown in FIG. 4 is an example and is not limited to this.

[0017] 5(a) and 5(b) are explanatory diagrams of the pouring angle of the grease Lc. For example, as shown in FIG. 5(a), a predetermined area AR2 including the distal end DE may be defined so that the pouring angle θ3 at the start of use of the liquid product PR (i.e., when the grease Lc is filled to its maximum) is equal to or greater than a predetermined angle, and the multiple openings AP1 to AP3 may be arranged to avoid this. This increases the pouring angle, thereby preventing dripping, especially when a large amount of grease Lc remains in the container body 20. On the other hand, if the pouring angle is shallow, as shown in FIG. 5(b), the grease Lc may drip from the spout 111 onto the top wall 116 of the cap body 11, the outer tube 114, or the like. For example, the pouring angle θ3 may be 60 degrees or more, 65 degrees or more, 70 degrees or more, 71 degrees or more, 72 degrees or more, 73 degrees or more, 74 degrees or more, 75 degrees or more, 76 degrees or more, 77 degrees or more, 78 degrees or more, 79 degrees or more, or 80 degrees or more and 85 degrees or more.

[0018] In this embodiment, the annular region AR1 is a region of the bottom wall 113 excluding a central region AR3 including the center C1 in a plan view (when viewed in the axial direction of the peripheral wall 112). The size of the central region AR3 can be set as appropriate. In this embodiment, the annular region AR1 is positioned to include the outermost portion of the bottom wall 113 in a plan view. However, multiple openings may be formed in an annular region located more inward than the annular region AR1. For example, the annular region may be defined so that the outermost portion of the annular region coincides with the outermost portion of the dome portion 113a of the bottom wall 113. Alternatively, the annular region may be defined so that the outermost portion of the annular region is located more inward than the outermost portion of the dome portion 113a. Furthermore, at least one of the multiple openings may be formed both inside and outside the annular region AR1. Furthermore, additional openings may be formed at positions other than the annular region AR1.

[0019] In this embodiment, the angle (angle θ1, angle θ2) between the virtual line VL1 and the virtual line VL2 (virtual line VL2a, virtual line VL2b) is 15 degrees or greater. Here, the virtual line VL1 connects the center C1 and the distal end DE of the bottom wall 113, and the virtual line VL2 connects the center C1 and the position of each opening (opening AP1, opening AP2) closest to the distal end DE. This ensures a predetermined area AR2, allowing the angle during pouring to be relatively deep. The angle between the virtual line VL1 and the virtual line VL2 may be, for example, 18 degrees or greater, 20 degrees or greater, 23 degrees or greater, 25 degrees or greater, 28 degrees or greater, 30 degrees or greater, 33 degrees or greater, 35 degrees or greater, 40 degrees or greater, or 45 degrees or greater.

[0020] Furthermore, in this embodiment, each of the plurality of openings AP1 to AP3 overlaps with at least one of the other openings included in the plurality of openings AP1 to AP3 in the rotation axis direction D2 of the rotation portion 13. Specifically, openings AP1 and AP3 overlap in a section S1 in the rotation axis direction D2, and openings AP2 and AP3 overlap in a section S2 in the rotation axis direction D2. Furthermore, the plurality of openings AP1 to AP3 are continuous in the rotation axis direction D2. Specifically, at least one of the plurality of openings AP1 to AP3 is provided over a section S3 in the rotation axis direction D2. This arrangement of the openings facilitates the joining of the grease Lc discharged from each opening. Therefore, branching of the grease Lc discharged from each opening can be suppressed, improving the ease of use of the container 1 to which the cap 10 is attached. For example, in the arrangement of the openings in this embodiment, the grease Lc discharged from opening AP3 overlaps with the grease Lc discharged from openings AP1 and AP2, causing the grease Lc discharged from each opening to join.

[0021] In this embodiment, the multiple openings AP1 to AP3 include an opening group G1 consisting of at least one opening (openings AP1 and AP2) and an opening group G2 consisting of at least one opening (opening AP3). The opening group G1 is located farther from the pivot portion 13 than the opening group G2, and the opening groups G1 and G2 are spaced apart in the direction along the imaginary line VL1. In this embodiment, no openings are provided in a section S4 between the opening groups G1 and G2 in the direction along the imaginary line VL1. When the container body 20 with the cap 10 attached is gradually tilted in the pouring direction D1, a small amount of grease Lc is initially poured out from the openings AP1 and AP2 of the opening group G1. Even if the container body 20 is further tilted in the pouring direction D1, for a while, the grease Lc is poured out only from the openings AP1 and AP2 of the opening group G1. That is, when a small amount of grease Lc is to be poured, even if the container body 20 is tilted a little too much, a large amount of grease Lc will not be poured. Further tilting the container body 20 in the pouring direction D1 causes grease Lc to be poured from the opening AP3 of the opening group G2, resulting in a larger amount of grease Lc being poured overall. By providing the opening group G1 and the opening group G2 at a distance in the direction along the virtual line VL1 in this way, it becomes easy to adjust the pouring amount. The length of the section S4 may be, for example, 1 / n or more of the overall length L113 of the bottom wall 113 in the pouring direction D1. n may be, for example, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0022] Furthermore, in this embodiment, the openings AP1 and AP2 included in the opening group G1 are smaller than the opening AP3 included in the opening group G2. Therefore, the difference in the amount of grease Lc poured out when the grease Lc is poured out only from the openings AP1 and AP2 of the opening group G1 is greater than when the grease Lc is poured out from the openings AP1 and AP2 of the opening group G1 and the opening AP3 of the opening group G2. Therefore, a single spout 111 can be used to handle both small and large amounts of grease Lc. Note that the area of ​​each opening can be set as appropriate. For example, the total area of ​​at least one opening included in the opening group G2 may be greater than the total area of ​​at least one opening included in the opening group G1. Furthermore, for example, the total area of ​​at least one opening included in opening group G2 may be 1.0 times or more, 1.1 times or more, 1.2 times or more, 1.3 times or more, 1.4 times or more, 1.5 times or more, 1.7 times or more, 1.8 times or more, 2.0 times or more, 2.25 times or more, 2.5 times or more, or 3 times or more the total area of ​​at least one opening included in opening group G1.

[0023] Moreover, in this embodiment, the inner surface of the opening AP3 included in the opening group G2 is linear. Forming the inner surface of the opening AP3 linearly allows for relatively fast drawing of the liquid. Specifically, in the case of relatively viscous grease Lc, the grease Lc may remain on the bottom wall 113 when the container 1 is returned from a tilted state to its original position. The surface tension of the grease Lc affects how easily the grease Lc remains (how difficult it is to draw the liquid). Depending on the size of the opening provided in the bottom wall 113, the effect of surface tension becomes relatively large, making it difficult for the grease Lc to fall from the bottom wall 113 into the container body 20. Therefore, from the perspective of accelerating the drawing of the liquid, it is considered to ensure that the area of ​​the opening provided in the bottom wall 113 is relatively large. Forming the inner surface of the opening AP3 linearly makes it easier to ensure the area of ​​the opening AP3, so that the grease Lc on the bottom wall 113 can be returned to the container body 20 relatively quickly (accelerating the drawing of the liquid). For example, the imaginary opening VAP3 shown in FIG. 4 has a partial ring shape, and its radial length LV is the same as the radial length of the circumferential end of the opening AP3. By forming the inside of the opening AP3 linearly, the opening can be made larger than the imaginary opening VAP3, relatively reducing the influence of surface tension and making it less likely for the grease Lc to accumulate. Furthermore, the imaginary opening VAP3 has a smaller radial dimension than the circumferential dimension, and the influence of surface tension can be greater depending on the radial dimension. In contrast, the radial dimension of the opening AP3 can be made larger than that of the imaginary opening VAP3, so the influence of surface tension can be relatively reduced. Furthermore, in this embodiment, the outer side of the opening AP3 included in the opening group G2 is arc-shaped, and the openings AP1 and AP2 included in the opening group G1 are partial ring-shaped.

[0024] The bottom wall 113 also includes a dome portion 113a, which is a dome-shaped portion that protrudes toward the spout 111. The inclusion of the dome portion 113a in the bottom wall 113 can accelerate the wicking of the grease Lc on the bottom wall 113. If the wicking is slow, for example, when the container 1 is used repeatedly at short intervals, the top lid 12 may be opened while the grease Lc remains on the bottom wall 113, resulting in the grease Lc spraying or dripping. In this embodiment, these problems can be prevented by accelerating the wicking, thereby improving the convenience of the cap 10. For example, the upper surface of the dome portion 113a (the surface facing the spout 111) may be hemispherical or partially spherical. Furthermore, for example, the upper surface of the dome portion 113a (the surface facing the spout 111) may be configured without a flat portion that extends horizontally when the container 1 is placed on a horizontal surface. The absence of a flat portion can accelerate the wicking of the grease Lc. In addition, bottom wall 113 includes a connection portion 113b that connects dome portion 113a and lower end portion 112b of peripheral wall 112. Connection portion 113b slopes downward from lower end portion 112b of peripheral wall 112 to dome portion 113a.

[0025] In this embodiment, the plurality of openings AP1 to AP3 are formed from the connecting portion 113b to the dome portion 113a. At least one of the plurality of openings AP1 to AP3 may be formed only in the dome portion 113a or only in the connecting portion 113b. At least one of the plurality of openings AP1 to AP3 may also be formed on the peripheral wall 112.

[0026] In this embodiment, the connecting portion 113b is inclined downward toward at least one of the plurality of openings AP1 to AP3. This can accelerate the drawing of the grease Lc on the bottom wall 113. Furthermore, after the grease Lc is poured out, the grease Lc tends to remain on the downstream side of the bottom wall 113 in the pouring direction D1. In this embodiment, the connecting portion 113b is inclined toward the openings AP1 and AP2 located downstream in the pouring direction D1, thereby accelerating the drawing of the grease Lc on the downstream side in the pouring direction D1 where the grease Lc is likely to remain.

[0027] 6(a) and 6(b) are diagrams showing examples of slopes provided at the connecting portion 113b of the bottom wall 113. FIG. 6(a) shows slope k1 sloping downward toward the opening AP1 and slope k2 sloping downward toward the opening AP2. FIG. 6(b) shows slope k3 sloping downward toward the opening AP3. The slopes k1 to k3 make it easier for the remaining grease Lc to flow in the direction of the arrows in the figure, thereby accelerating the drainage of the grease Lc. The slopes k1 to k3 of the connecting portion 113b also slope downward from the lower end 112b of the peripheral wall 112 toward the dome portion 113a. The upper end of the portion of the connecting portion 113b where the slopes k1 to k3 are provided is located higher than the other portions of the connecting portion 113b.

[0028] (Outer cylinder 114) The outer cylinder 114 is provided so as to surround the opening 21 of the container body 20 when the cap 10 is attached to the container body 20. The inner surface of the outer cylinder 114 is provided with an outer seal 114a that forms a seal with the opening 21 of the container body 20, and an engagement portion 114b that engages with the opening 21 to define the positional relationship with the opening 21. The outer surface of the outer cylinder 114 is also provided with a recess 114c that has a shape corresponding to the cover 124 of the top lid 12, which will be described later. In this embodiment, the central axis of the outer cylinder 114 and the central axis of the bottom wall 113 are approximately aligned, but the central axis of the bottom wall 113 may be positioned closer to the pouring direction D1 or the rotating portion 13 side than the central axis of the outer cylinder 114.

[0029] (Inner cylinder 115) The inner cylinder 115 is provided so as to be positioned inside the opening 21 of the container body 20 when the cap 10 is attached to the container body 20. An inner seal 115a that forms a seal between the inner cylinder 115 and the opening 21 is provided on the outer surface of the inner cylinder 115.

[0030] (Ceiling wall 116, protrusion 117, connecting wall 118) Top wall 116 is provided to connect the upper end of outer cylinder 114 and the upper end of inner cylinder 115. Protrusion 117 is provided to protrude upward from top wall 116 around the entire periphery of top wall 116. Connection wall 118 is provided to connect top wall 116 and peripheral wall 112.

[0031] The protrusion 117 and the connecting wall 118 form an annular groove 119 on the upper surface of the top wall 116. Even if the oil Lc drips from the spout 111, the oil Lc remains in this groove 119, thereby preventing the liquid product from dripping down to the outer tube 114.

[0032] As described above, the cap 10 of this embodiment has a plurality of openings AP1 to AP3 formed in the annular region AR1 of the bottom wall 113, through which the liquid food Lc in the container can pass. The plurality of openings AP1 to AP3 are formed in the annular region AR2, avoiding a predetermined region AR2 including the distal end DE that is the farthest from the pivoting part 13. This results in a deeper pouring angle compared to when openings are formed in the predetermined region AR2 including the distal end DE, making it possible to suppress dripping more effectively than before.

[0033] <Top lid 12> Please refer to Figures 1, 2 and 7. Figure 7 is a front view of the top cover 12. Top lid 12 can be opened and closed relative to cap body 11, and when closed, can cover spout 111 of cap body 11. Top lid 12 includes a cylindrical outer peripheral wall 121 and a top wall 122 that closes the upper part of outer peripheral wall 121. Top lid 12 also includes a flange 123 that extends outward from outer peripheral wall 121, and a cover 124 that extends downward from the lower end of outer peripheral wall 121 below flange 123.

[0034] (Outer wall 121, flange 123) Outer peripheral wall 121 is provided to surround spout 111 when top lid 12 is closed. An engagement portion 121a that engages with protrusion 117 of cap body 11 is formed on the inner surface of outer peripheral wall 121. By engaging with protrusion 117, engagement portion 121a restricts movement of top lid 12 relative to cap body 11 when top lid 12 is closed.

[0035] (Tsuba 123) The flange 123 is provided on the side of the outer peripheral wall 121 opposite to the side on which the rotating portion 13 is provided. The user can open the top cover 12 by hooking their finger on the lower surface 123a of the flange 123.

[0036] In this embodiment, the lower surface 123a of the flange 123 has an upwardly convex curved shape. This increases the contact area between the flange 123 and the user's fingers compared to when the lower surface 123a does not have an upwardly convex curved shape (for example, when the lower surface is flat). As a result, the pressure exerted on the user's fingers when opening the top cover 12 can be relatively reduced.

[0037] In particular, in the case of a cap that does not require uncorking with a pull ring, it is necessary to improve the sealing between the top lid 12 and the spout 111 compared to a cap that is provided with a pull ring. Therefore, a cap that does not require uncorking with a pull ring requires a greater force (moment around the axis of the pivoting part 13) to open the top lid 12 than a cap that is provided with a pull ring, and the top lid 12 tends to be difficult to open. In this regard, in this embodiment, in a cap that does not require uncorking with a pull ring, the underside 123a of the flange 123 has an upwardly convex curved shape, which relatively reduces the pressure on the user's fingers when opening the top lid 12, making it easier to open the top lid 12.

[0038] The size of the flange 123 can also be set appropriately. For example, the length of the flange 123 along the circumferential direction of the outer peripheral wall 121 may be 1 / n or more of the outer peripheral length of the outer peripheral wall 121. n may be, for example, 2, 3, 4, or 5. If the outer peripheral length of the outer peripheral wall 121 varies depending on the position in the up-down direction, the longest outer peripheral length of the outer peripheral wall 121 may be used as the reference. The longer the flange 123 in the circumferential direction, the greater the contact area between the flange 123 and the fingers, and therefore the pressure applied to the user's fingers when opening the top lid 12 can be relatively reduced.

[0039] Furthermore, the amount of radial protrusion of flange 123 from outer peripheral wall 121 may be equal to or greater than 1 / n of the radius of outer peripheral wall 121. n may be, for example, 2, 3, 4, or 5. The greater the amount of radial protrusion of flange 123, the greater the contact area between flange 123 and the fingers, and therefore the pressure on the user's fingers when opening top lid 12 can be relatively reduced.

[0040] (Cover 124) Cover 124 is provided below flange 123, extending downward from lower end 121b of outer peripheral wall 121. By providing cover 124, it is possible to prevent the user's fingers from coming into contact with spout 111 when opening top lid 12.

[0041] The length of cover 124 along the circumferential direction of outer peripheral wall 121 may be approximately the same as the length of flange 123, or may be equal to or greater than the length of flange 123. By specifying the relationship between the circumferential lengths of flange 123 and cover 124 in this manner, it is possible to more effectively cover areas that are likely to be touched by the user's fingers. However, the length of cover 124 along the circumferential direction of outer peripheral wall 121 may be shorter than the length of flange 123.

[0042] The vertical length of cover 124 can also be set, for example, as follows: For example, in the portion where flange 123 and cover 124 overlap in the circumferential direction, the average length from underside 123a of flange 123 to the lower end of cover 124 may be 3 mm or more, 4 mm or more, 5 mm or more, 6 mm or more, 8 mm or more, 10 mm or more, 12 mm or more, 14 mm or more, 16 mm or more, or 40 mm or less, 30 mm or less, 25 mm or less, 22 mm or less, 20 mm or less. Alternatively, the minimum value of this length may be 3 mm or more, 4 mm or more, 5 mm or more, 6 mm or more, 8 mm or more, 10 mm or more, 12 mm or more, 14 mm or more, 16 mm or more, or 40 mm or less, 30 mm or less, 25 mm or less, 22 mm or less, 20 mm or less.

[0043] In this embodiment, the width of the lower end 124b of the cover 124 is narrower than the width of the upper end 124a (the portion connected to the lower end 121b of the outer peripheral wall 121). However, the width of the lower end 124b may be wider than the width of the upper end 124a (the length along the circumferential direction of the outer peripheral wall 121), or the two widths may be equal.

[0044] Furthermore, in this embodiment, the cover 124 is positioned so that its outer surface is exposed when the top lid 12 is closed. More specifically, the cover 124 is positioned on the outside of the outer tube 114 of the cap body 11. This allows the user to recognize the presence of the cover 124 before opening the top lid 12, making it easier to hook their finger at an appropriate position on the flange 123. In other words, if the outer surface of the cover 124 is not exposed when the top lid 12 is closed, the user will not be able to recognize the presence of the cover 124, so it is conceivable that the user will only hook their finger at the tip of the flange 123 to avoid their finger coming into contact with the spout 111. On the other hand, if the outer surface of the cover 124 is exposed, the user will be able to easily hook their finger all the way to the base of the flange 123, making it easier to transmit the force of their finger to the flange 123.

[0045] In addition, in this embodiment, region 121c of outer peripheral wall 121 extending downward from the portion where it connects to the underside of flange 123 and the outer surface of cover 124 are formed on the same plane. No unnecessary steps or the like are provided below flange 123, making it easier for the user to open top lid 12. Furthermore, in this embodiment, when top lid 12 is closed, cover 124 and region 114d, which is on the outer surface of outer tube 114 of cap body 11 and adjacent to the lower end of cover 124, are formed on the same plane. From this perspective, too, no unnecessary steps or the like are provided below flange 123, making it easier for the user to open top lid 12.

[0046] (Ceiling wall 122) The top wall 122 is provided to close the upper portion of the outer peripheral wall 121. The top wall 122 includes a sealing portion 122a and a suppressing portion 122b. The sealing portion 122a extends from the underside of the top wall 122 toward the inside of the spout 111 and forms a seal with the outer peripheral wall 112. In this embodiment, the sealing portion 122a forms two annular seals 122a1 and 122a2 with the outer peripheral wall 112. The sealing portion 122a forms a seal between the cap body 11 and the top lid 12 when the top lid 12 is closed. The sealing portion 122a also includes a fin-shaped portion 122d on the rotating portion 13 side. The fin-shaped portion 122d suppresses oil Lc dripping from the top lid 12 from adhering to the rotating portion 13 or the outer cylinder 114 adjacent to the rotating portion 13 when the container 1 is tilted for pouring. The suppression portion 122b extends downward from the underside of the top wall 122 and is provided to cover the outside of the spout 111. For example, when the container 1 falls over, the oil Lc accumulates in the R-shaped portion 122c of the top wall 122, and the suppression portion 122b prevents the accumulated oil Lc from dripping near the rotating portion 13 during use.

[0047] Furthermore, an R-shaped portion 122c, which is a R-shaped part, is formed on the lower surface of the top wall 122. When the top cover 12 is closed, the R-shaped portion 122c is located above a flow path FP for grease Lc formed in the cap body 11. The provision of the R-shaped portion 122c makes it easier for grease Lc adhering to the lower surface of the top wall 122 to fall into the flow path FP. Furthermore, in this embodiment, the R-shaped portion 122c has R shapes with different radii of curvature formed at a connection portion 122c1 between the lower surface of the top wall 122 and the seal portion 122a and an inner portion 122c2 of the connection portion 122c1.

[0048] <Other embodiments> 8 is a cross-sectional view of the liquid product PR according to one embodiment, showing a state in which the cap 910 and the top cover 912 are closed. Hereinafter, the same components as those in the cap 10 will be assigned the same reference numerals and descriptions thereof will be omitted.

[0049] The cap 910 of this embodiment differs from the cap 10 in that the cover 924 of the top lid is positioned outside the outer surface of the outer cylinder. That is, in this embodiment, when the top lid 12 is closed, the cover 924 is positioned outside a region 114d on the outer surface of the outer cylinder 114 of the cap body 11, adjacent to the lower end of the cover 924. An outer ring 916a is provided between the outer cylinder 114 and the inner cylinder 115, forming a seal with the outside of the end of the opening 21 of the container body 20. By positioning the cover 924 further outward, the mold insert wall thickness is ensured, and the outer ring 916a suppresses leakage of the grease Lc, particularly when the container 1 is dropped and subjected to an impact.

[0050] 9(a) to 9(f) show examples of the arrangement of multiple openings provided in the bottom wall 113. Here, the openings included in the opening group G1 are referred to as openings APG1, and the openings included in the opening group G2 are referred to as openings APG2. For example, the openings may be formed only in the connecting portion 113b of the bottom wall 113 (FIGS. 9(a) to 9(d)), or only in the dome portion 113a (FIG. 9(e)). The shape and size of each opening, as well as the size of the predetermined area AR2 including the distal end DE where no openings are arranged, can be changed as appropriate. For example, all of the openings included in the opening group G1 and the opening group G2 may be the same size or shape. Alternatively, the total area of ​​the openings APG1 included in the opening group G1 may be larger than the total area of ​​the openings APG2 included in the opening group G2. Alternatively, the total area of ​​the openings APG1 included in the opening group G1 may be equal to the total area of ​​the openings APG2 included in the opening group G2. Alternatively, the total area of ​​the openings APG2 included in the opening group G2 may be configured to be smaller than the total area of ​​the openings APG1 included in the opening group G1.
