Abstract
Description
[Technical field]
[0001] The present invention relates to a cap that is attached to the mouth of a container. [Background technology]
[0002] The cap is attached to the mouth of a container that contains liquid inside, and forms a spout for pouring the liquid from the container to the outside (see, for example, Patent Document 1). As shown in FIG. 1 and paragraph
[0029] of Patent Document 1, the cap (hinge cap) described in Patent Document 1 has, as a buffer mechanism 28, an annular side wall 48 that hangs down from the periphery of the spout 24 and a flow rate adjustment plate (bottom plate 50) that closes the lower end of the side wall 48. The side wall 48 is formed with a plurality of slit-like openings 48a at intervals in the circumferential direction to allow the liquid (content liquid) to pass through. This buffer mechanism 28 reduces the momentum of the liquid (content liquid) when the container is tilted to pour out the liquid (content liquid). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2019-189324 A Summary of the Invention [Problem to be solved by the invention]
[0004] In the cap (hinge cap) described in Patent Document 1, when the container is tilted, the liquid (content liquid) whose momentum has been softened by the buffer mechanism 28 passes through the outlet 24 and is then poured out. Therefore, even if the momentum of the liquid (content liquid) is once softened by the buffer mechanism 28, it will be accelerated again when it is poured out from the outlet 24. Therefore, when focusing on the liquid (content liquid) poured out of the cap (hinge cap) and the container, the momentum is not sufficiently softened as a result.
[0005] In particular, when the liquid (contents) is a liquid seasoning such as soy sauce, the liquid seasoning (such as soy sauce) poured out of the spout 24 accelerates and reaches a small plate or food, causing the liquid seasoning (such as soy sauce) to splash, which may stain surrounding tables or clothes.
[0006] SUMMARY OF THE PRESENT EMBODIMENT An object of the present invention is to provide a cap that can prevent the surrounding area from being contaminated by poured liquid. [Means for solving the problem]

[0012] A cap according to a sixth aspect of the present invention is the cap according to any one of the first to fifth aspects of the present invention, wherein the flow rate adjusting plate has a downward convex portion that protrudes downward at the center thereof. Effect of the Invention
[0013] According to the cap, the force of the liquid from the spout is moderated by the flow rate adjusting plate, so that the liquid that reaches the target outside the container is less likely to splash. Even if the liquid splashes inside the container, the liquid does not pass through the opening facing the side of the support part. Therefore, it is possible to prevent the liquid from contaminating the surroundings. [Brief description of the drawings]

[Figure 6] FIG. 11 is a vertical cross-sectional view of a cap according to another embodiment of the present invention attached to a container. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] A cap according to an embodiment of the present invention will now be described with reference to Figs.
[0016] 1 and 2, this cap 1 is attached to the mouth m of a container B in which a liquid L such as a liquid seasoning is stored, and serves to soften the force of the liquid L and pour it out of the container B. To achieve this, the cap 1 includes a lid body 2 attached to the mouth m of the container B, a pouring tube 3 provided on the lid body 2, a pouring plate 4 provided inside the pouring tube 3 and having a pouring outlet 5 formed therein, a flow rate adjustment plate 6 disposed above the pouring outlet 5, and a support portion 7 supporting the flow rate adjustment plate 6 from the pouring plate 4. The support portion 7 has an opening 8 that communicates with the pouring outlet 5 and faces to the side.
[0017] The pouring tube 3 preferably has an air replacement hole 31. The air replacement hole 31 is a hole that guides air into the interior of the container B when the liquid L is poured out from inside the container B through the pouring outlet 5 and the opening 8 of the support part 7. The air replacement hole 31 guides air into the interior of the container B when the liquid L is poured out from inside the container B through the pouring outlet 5 and the opening 8 of the support part 7, thereby suppressing pulsation of the poured liquid L. When the pulsation of the liquid L is suppressed, that is, when sudden fluctuations in the flow rate of the liquid L being poured out are suppressed, the flow rate of the liquid L being poured out becomes stable.
[0018] The total area of the openings 8 of the support part 7 is preferably larger than the total area of the air replacement holes 31. The number of openings 8 and air replacement holes 31 of the support part 7 is not limited to one each, and there may be multiple of each. By having the total area of the openings 8 of the support part 7 larger than the air replacement holes 31, a sufficient flow rate of the liquid L poured out from the openings 8 of the support part 7 is ensured.
[0019] It is preferable that the air replacement hole 31 is a hole facing laterally. Here, facing laterally with respect to the air replacement hole 31 (and opening 8 of the support part 7) is not limited to facing in a direction that is completely horizontal to the vertical axis V of the lid main body 2, and a deviation of up to ±10° from this horizontal direction is permitted. Because the air replacement hole 31 (and opening 8 of the support part 7) faces laterally, even if liquid L splashes up inside the container B, the splashed liquid L does not pass through the air replacement hole 31 (and opening 8 of the support part 7).
[0020] Preferably, the cap 1 includes a top cover 10 connected to the lid body 2 via a hinge 9, and as shown in FIG. 3, the opening 8 (8c) of the support part 7 is located on the opposite side of the hinge 9, and the air replacement hole 31 (31a) is located on the hinge 9 side. When the cap 1 includes the top cover 10, the user tries to pour out the liquid L from the opposite side of the top cover 10 (the opposite side of the hinge 9). Therefore, the liquid L is easily poured out from the opening 8 (8c) of the support part 7 located on the opposite side of the hinge 9. On the other hand, air is easily guided into the inside of the container B from the air replacement hole 31 (31a) on the hinge 9 side, which is difficult for the poured liquid L to reach. The opening 8 of the support part 7 may be located not only on the opposite side 8c of the hinge 9, but also on the hinge 9 side 8a, and between the opposite side 8c of the hinge 9 and the hinge 9 side 8a, 8b, 8d. Similarly, the air replacement hole 31 may be located not only on the hinge 9 side 31a, but also on the opposite side 31c of the hinge 9, and between the hinge 9 side 31a and the opposite side 31c of the hinge 9, 31b and 31d. By forming the openings 8 of the support part 7 and the air replacement holes 31 in many directions radially from the vertical axis V of the lid main body 2, the liquid L can be poured out more easily and air can be guided into the container B.
[0021] As shown in FIG. 1 and FIG. 4, the upper lid 10 is preferably detachable from the lid body 2. For example, an engagement tube 21 is provided on the outer periphery of the pouring tube 3, and the upper lid 10 is formed to be engageable with the engagement tube 21, as a configuration for being detachable. When the liquid L is not used, the user attaches the upper lid 10 to the lid body 2, and when the liquid L is used, the user removes the upper lid 10 from the lid body 2. As a result, even if the container B falls or tilts when the liquid L is not used, the upper lid 10 prevents the liquid L from flowing out. In order to ensure this prevention, the upper lid 10 preferably has an inner lid 11 that engages with the flow rate adjustment plate 6 and the pouring tube 3. The inner lid 11 has an inner recess 16 that surrounds the flow rate adjustment plate 6 and an outer periphery engagement portion 13 that engages with the pouring tube 3 when the upper lid 10 is attached to the lid body 2. When the upper lid 10 is attached to the lid body 2 by the inner lid 11, the flow rate adjusting plate 6 is surrounded by the inner recess 16, and the pouring tube 3 and the outer circumferential engagement portion 13 are engaged with each other. This engagement positions the upper lid 10 relative to the lid body 2, and reliably seals the pouring tube 3. The flow rate adjusting plate 6 and the inner recess 16 may be configured to engage with each other.
[0022] As shown in FIG. 1, the top lid 10 preferably has a gap 19 between the surface 15 facing the lid body 2 and the inner lid 11. As shown in FIG. 4, this gap 19 decreases (or disappears) when the top lid 10 is attached to the lid body 2. As a result, even if the top lid 10 is loosened from the lid body 2 due to the container B falling over or tilting, the inner lid 11 does not immediately come into contact with the locking protrusion 17, so the inner lid 11 is not subjected to an external force until it comes into contact with the locking protrusion 17. Therefore, even if the top lid 10 is loosened from the lid body 2, the engagement between the outer circumferential engagement portion 13 of the inner lid 11 and the pouring tube 3 is not released for a while until the inner lid 11 is moved by an external force, in other words, the engagement is maintained.
[0023] The flow rate adjusting plate 6 preferably has a downward convex portion 61 that protrudes downward at the center thereof. This downward convex portion 61 guides the liquid L from the spout 5 to the opening 8 of the support part 7, so that the flow rate of the liquid L poured out from the opening 8 of the support part 7 becomes stable.
[0024] The lid body 2 is not particularly limited as long as it has a structure that allows it to be attached to the mouth m of the container B, but for example, it has an outer cylinder part 27 that contacts the outer surface of the mouth m, and an inner cylinder part 28 that contacts the inner surface of the mouth m. That is, the lid body 2 is attached to the container B by the outer cylinder part 27 and the inner cylinder part 28 sandwiching the mouth m of the container B from the outer surface and the inner surface.
[0025] The lid body 2 preferably has a drip receiver 22 on the outer periphery of the pouring tube 3. After the liquid L is poured out of the pouring tube 3, most of the dripping is prevented by the flow rate adjustment plate 6, but some dripping may remain outside the pouring tube 3. This slight dripping is received by the receiver 22 formed on the outer periphery of the pouring tube 3, for example, the groove 22 formed between the pouring tube 3 and the engagement tube 21.
[0026] The material of the cap 1 is not particularly limited, but is preferably made of synthetic resin. By making the cap 1 from synthetic resin, the attachment of the lid body 2 to the mouth part m of the container B becomes easy, and further, the attachment and detachment of the lid body 2 and the top lid 10 becomes easy.
[0027] A method of using the cap 1 will now be described.
[0028] As shown in FIG. 4, the liquid L is sold together with the container B and the cap 1 in a state in which the cap 1 is attached to the mouth m of the container B containing the liquid L and the top lid 10 is attached to the lid body 2. If the liquid L contained in the container B is at a high temperature (a temperature higher than room temperature) when the cap 1 is attached to the mouth m of the container B, the temperature of the liquid L will then naturally drop, causing the inside of the container B to be in a reduced pressure state. If a user who has purchased such liquid L together with the container B and the cap 1 initially opens the cap 1, the aforementioned reduced pressure state may be suddenly released, causing the liquid L to splash up inside the container B. However, since the opening 8 and the air replacement hole 31 of the support part 7 are oriented to the side, the splashed up liquid L does not pass through the opening 8 and the air replacement hole 31 of the support part 7.
[0029] When using liquid L, a user removes top lid 10 from lid body 2 as shown in Fig. 1, and tilts container B so that the side of lid body 2 opposite top lid 10 (the side opposite hinge 9) faces down as shown in Fig. 5. As a result, liquid L stored inside container B passes through spout 5, as shown by the solid black arrow in Fig. 5, has its momentum softened by flow rate adjustment plate 6, and is guided by downward convex portion 61 to opening 8 of support portion 7 and poured out. At this time, air is guided into container B from air replacement hole 31 as shown by the hollow arrow in Fig. 5.
[0030] The poured liquid L reaches an object on which the user wishes to use the liquid L. If the liquid L is a liquid seasoning such as soy sauce, the object is, for example, a small dish or food.
[0031] In this way, according to the cap 1, the force of the liquid L from the spout 5 is softened by the flow rate adjusting plate 6, so that the liquid L that reaches the target outside the container B is less likely to splash. Even if the liquid L splashes up inside the container B, the liquid L does not pass through the opening 8 facing the side of the support part 7. Therefore, it is possible to prevent the liquid L from contaminating the surroundings.
[0032] Furthermore, the air replacement hole 31 suppresses pulsation of the liquid L and stabilizes the flow rate of the liquid L when it is poured out, so that contamination of the surroundings by the liquid L can be further prevented.
[0033] In addition, because the air replacement hole 31 faces to the side, even if the liquid L splashes up inside the container B, it does not pass through the air replacement hole 31, and as a result, contamination of the surroundings by the liquid L can be further prevented.
[0034] Furthermore, since the opening 8 of the support part 7 has a total area larger than that of the air replacement hole 31, a sufficient flow rate of the liquid L poured out from the opening 8 of the support part 7 is ensured, so that the user does not need to tilt the container B excessively to pour out the liquid L, thereby further preventing contamination of the surrounding area by the liquid L.
[0035] In addition, the liquid L can be more easily poured out and air can be guided into the inside of the container B through the opening 8 of the support part 7 located on the opposite side of the hinge 9 and the air replacement hole 31 located on the hinge 9 side, thereby further preventing contamination of the surrounding area by the liquid L.
[0036] In addition, the downward convex portion 61 of the flow rate adjustment plate 6 guides the liquid L from the pouring outlet 5 to the opening 8 of the support part 7, thereby stabilizing the flow rate of the liquid L poured out from the opening 8 of the support part 7, thereby further preventing contamination of the surrounding area by the liquid L.
[0037] Incidentally, in the above embodiment, no explanation was given about the shapes of the opening 8 in the support part 7 and the air replacement hole 31, but there are no particular limitations as long as they guide the liquid L and the air, respectively. As an example, the shape of the opening 8 in the support part 7 and the air replacement hole 31 may be rectangular, trapezoidal (for example, an isosceles trapezoid whose lower base is longer than its upper base), circular, or the like.
[0038] Further, in the above embodiment, the area of the outlet 5 has not been described, but there is no particular limitation as long as the outlet 5 allows the liquid L to pass through. The area of the outlet 5 is preferably larger than the area of the pouring plate 4. This is because the flow rate of the liquid L poured out is stabilized, and contamination of the surroundings by the liquid L can be further prevented.
[0039] Furthermore, in the above embodiment, the pouring plate 4 is horizontal with respect to the vertical axis V of the lid main body 2, but is not limited thereto. For example, as shown in Fig. 6, the pouring plate 4 may be inclined so that the side of the vertical axis V is downward (the side opposite to the vertical axis V is upward). By inclining the pouring plate 4 in this manner, an effect is achieved in that the liquid L is easily allowed to flow down the pouring plate 4 and return to the inside of the container B.
[0040] In addition, although the above embodiment does not describe the molding of the inner lid 11, the inner lid 11 may be molded integrally with other components of the top lid 10 and then separated from the surface 15 of the top lid 10.
[0041] Furthermore, the above-mentioned embodiment is illustrative in all respects and is not restrictive. The scope of the present invention is indicated by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims. Among the configurations described in the above-mentioned embodiment, those other than the configuration described as the first invention in "Means for solving the problem" are optional configurations and can be deleted and modified as appropriate.
