[0033] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0034] Figure 1 is a side view of a container for illustrating an embodiment. Figure 1 As shown, the container 1 of this embodiment includes a spout 2 and a container body 3 storing liquid. The spout 2 is attached to the container body 3 and is used to pour out the oily liquid stored in the container body 3.

[0035] The liquid stored in the container body 3 is an oily liquid. Here, the oily liquid refers to a liquid containing oil such as cooking oil and sauce. For example, as cooking oil, linseed oil, perilla oil, olive oil, grape seed oil, corn oil, sesame oil, rice bran oil, soybean oil, rapeseed oil, palm oil, sunflower oil, safflower oil, cottonseed oil, peanut oil, etc. can be cited. In addition, for the present invention, as long as it is an oily liquid that is liquid at room temperature, it is not limited to this and can be used for any liquid. In addition, the present invention can also be used for viscous paste-like materials (such as paste-like margarine, etc.).

[0036] The container body 3 can be formed using, for example, a resin container, a paper container, a glass container, etc. Among the materials of the resin container, for example, polyolefin resins such as polypropylene and polyethylene, polyester resins such as polyethylene terephthalate, etc. can be used.

[0037] like Figure 1 As shown, the outflow piece 2 is mounted on the upper part of the container body 3. The outflow piece 2 may be formed integrally with the container body 3. For example, in the case of a resin container 1, the outflow piece 2 and the container body 3 may be formed integrally by using a mold having a shape in which the outflow piece 2 and the container body 3 are integrated. In addition, the outflow piece 2 may be configured to be separable from the container body 3. For example, after the liquid in the container 1 is used, the outflow piece 2 (e.g., plastic) and the container body 3 (e.g., paper, glass) may be separated so that they can be discarded separately.

[0038] Figure 2 It is a side view for explaining the outflow piece of this embodiment. Figure 3 2 is a cross-sectional view and a top view showing the outflow piece of the present embodiment. Figure 3 The cover 11 is omitted in the figure. Figures 4 to 14 The same is true in Chinese.

[0039] like Figure 2 As shown, the outflow piece 2 of this embodiment includes an outflow port 10 and a cover 11. Figure 3 As shown in FIG. 1 , the outflow port 10 is a cylindrical structure having an opening 19 inside. The oily liquid stored in the container body 3 is poured out of the container 1 through the opening 19 provided in the outflow port 10. Figure 2 As shown, the cover 11 is attached to the outflow port 10 via the hinge 12. That is, the cover 11 is rotatably attached to the outflow port 10 by the hinge 12, thereby enabling the upper surface of the outflow port 10 to be opened and closed. Figure 1 Indicates the state where the outflow port 10 is closed, Figure 2 This shows a state where the outflow port 10 is open.

[0040] In addition, Figure 1 , Figure 2 , a structure example in which the cover 11 is attached to the outlet 10 via the hinge 12 is shown, but in this embodiment, the cover 11 may be screwed to the outlet 10. In this case, by rotating the cover 11, the cover 11 can be removed from the outlet 10, or the outlet can be covered with the cover 11. Figure 2 , Figure 3 In the embodiment, the shape of the outlet 10 is a cylindrical shape, but in the present embodiment, the shape of the outlet 10 may be a shape other than a cylindrical shape. For example, the shape of the outlet 10 in plan view may be an ellipse or a polygon such as a quadrilateral.

[0041] In this embodiment, if Figure 2 , Figure 3 As shown in FIG. 1 , an oil-repellent finish 13 is applied to the outer side of the outflow port 10. Thus, by applying the oil-repellent finish 13 to the outer side of the outflow port 10, dripping when pouring out the oily liquid can be suppressed. Figure 3 In order to clearly indicate the position of the oil-repellent finish 13 , the portion of the surface of the outflow port 10 where the oil-repellent finish 13 is applied is shown thick. However, in reality, the portion where the oil-repellent finish 13 is applied is thinner than the surface of the outflow port 10 .

[0042] Figure 5 2 is a cross-sectional view for explaining the pouring of liquid using a conventional outflow member. Figure 5 As shown in the left figure, when the liquid 121 is poured out from the outflow port 110 using the outflow piece 102 of the prior art, the liquid 121 is poured out in a state where a part of the liquid 121 spreads to the outside of the outflow port 110 (the part where the liquid spreads is indicated by the symbol 122).

[0043] Afterwards, if Figure 5As shown in the right figure of FIG. 1 , when the outflow piece 102 is restored to a vertical position in order to stop the outflow of the liquid 121, the liquid 122 that has spread to the outside of the outflow port 110 remains outside the outflow piece 102, and the remaining liquid 123 flows outside the outflow piece 102 (container) and drips. In particular, in the case of a liquid with a high viscosity such as an oily liquid, such dripping occurs significantly.

[0044] In contrast, in the invention of this embodiment, Figure 2 , Figure 3 As shown in FIG. 1 , since the outer side of the outflow port 10 is subjected to an oleophobic treatment 13, it is possible to suppress dripping when pouring out the oily liquid. Figure 4 Provide detailed explanation.

[0045] Figure 4 2 is a cross-sectional view for explaining the pouring of liquid using the outflow piece of this embodiment. Figure 4 As shown in the left figure of FIG. 1 , when the liquid 21 is poured out from the outflow port 10 using the outflow piece 2 of the present embodiment, since the oleophobic processing 13 is applied to the outer side of the outflow port 10, it is possible to suppress a part of the liquid 21 from spreading to the outer side of the outflow port 10. That is, when the oleophobic processing 13 is applied to the outer side of the outflow port 10, the oleophobic processing 13 can suppress the liquid 21 from adhering to the outer side of the outflow port 10. Therefore, it is possible to suppress a part of the liquid 21 from spreading to the outer side of the outflow port 10.

[0046] Thus, in this embodiment, since it is possible to suppress a part of the liquid 21 from spreading to the outside of the outflow port 10, Figure 4 As shown in the right figure of , it is possible to suppress dripping when the outflow piece 2 is restored to verticality in order to stop the outflow of the liquid 21. That is, in this embodiment, since the oil-repellent processing 13 is applied to the outer side of the outflow port 10, it is possible to suppress the liquid 22 from remaining on the outer side of the outflow port 10. Therefore, it is possible to suppress dripping.

[0047] In addition, Figure 1 , an example in which the outflow piece 2 is installed on the upper part of the container body 3 is shown, but in the present embodiment, it can also be installed on the inclined surface of a paper container having an inclined surface on the upper part of the container body (i.e., a paper container having a roof shape on the upper part). In the case where the outflow piece 2 is installed on the inclined surface of the container having a roof shape in this way, when the container body is placed, the opening of the outflow piece 2 is not horizontal, so it is easy to drip. In particular, when the liquid contained in the container body is nearly full, the liquid will be poured out from the outflow piece 2 by simply tilting the container slightly, so it is easy to drip. Therefore, when the outflow piece 2 of the present embodiment is installed on the inclined surface of such a container having a roof shape, the effect of the present invention is particularly significant.

[0048] In addition, Figures 2 to 4 , an example is shown in which the oil-repellent treatment 13 is applied to the entire circumference of the outer side of the outflow outlet 10, but in this embodiment, the oil-repellent treatment may be applied to at least the outer side of the outflow outlet 10 where the liquid passes when pouring the liquid 21. For example, the oil-repellent treatment 13 may be applied to half of the outer circumference of the outflow outlet 10 where the liquid passes when pouring the liquid 21.

[0049] In addition, in the present embodiment, the oleophobic process 13 is a process for repelling oil, in other words, a process for increasing the contact angle of oil, and can be implemented, for example, by coating an oleophobic agent on the surface of the outflow port 10. For example, the oleophobic agent can include fluorine-based oleophobic agents, silicone-based oleophobic agents, Teflon-based oleophobic agents, and the like.

[0050] In addition, in the present embodiment, the oil-repellent processing 13 may be performed by adding fine particles to the resin material, which is the raw material of the outflow port 10. In this way, by adding fine particles to the resin material, which is the raw material of the outflow port 10, it is possible to form unevenness on the surface of the outflow port 10 after molding, and to impart oil repellency. For example, the fine particles may be inorganic materials such as metal oxides (for example, silicon dioxide, aluminum oxide, etc.), organic materials such as resin cured products, etc. There is no particular limitation on the particle size of the fine particles as long as it is a particle size that can impart oil repellency, and for example, it may be set to be 5 μm or more and 100 μm or less.

[0051] According to the invention of the present embodiment described above, it is possible to provide a spout and a container capable of suppressing dripping when pouring an oily liquid.

[0052] Next, other configuration examples of the outflow piece according to the present embodiment will be described.

[0053] In this embodiment, it is possible to Figure 6 As shown in the outflow piece 2a, the outer side of the outflow outlet 10 and the top surface of the outflow outlet 10 (the surface on the front end side of the outflow outlet 10) are subjected to oil repellent processing 13a. In this way, by also applying the oil repellent processing 13a to the top surface of the outflow outlet 10, it is possible to suppress the liquid from adhering to the top surface of the outflow outlet 10, and it is possible to effectively suppress the occurrence of dripping.

[0054] In addition, in this embodiment, it is also possible to Figure 7 As shown in the outflow piece 2b, the outer side of the outflow outlet 10, the top surface of the outflow outlet 10 (the surface on the front end side of the outflow outlet 10), and the inner side of the outflow outlet 10 are subjected to oil repellent processing 13b. In this way, by also applying the oil repellent processing 13b to the inner side of the outflow outlet 10, it is possible to suppress the liquid from adhering to the inner side of the outflow outlet 10, and it is possible to effectively suppress the occurrence of dripping.

[0055] For example, in this embodiment, the entire surface of the outflow port 10 may be subjected to an oleophobic treatment 13b. For example, by using an oleophobic material as a raw material when manufacturing the outflow piece 2b, the entire surface of the outflow port 10 after manufacturing can be made oleophobic. For example, by using a silicone resin to manufacture the outflow piece 2b, the entire surface of the outflow port 10 can be made oleophobic.

[0056] In the present embodiment, the outer side and the inner side (except the top surface of the outflow port 10 ) of the outflow port 10 may be subjected to an oil-repellent treatment (not shown).

[0057] In addition, in this embodiment, it is also possible to Figure 8 As shown in the outflow piece 2c, the shape of the outflow port 10c is set to a shape in which the edge of the front end of the outflow port 10c expands outward and then turns back. Figure 8 As shown in the outflow piece 2c, the lower side of the folded portion at the front end of the outflow outlet 10c is subjected to an oil-repellent finish 14. In addition, in this specification, the portion of the outflow outlet 10c to which the oil-repellent finish 14 is applied may also be referred to as the outer side (periphery) of the outflow outlet 10c (that is, continuously connected to the outer surface of the outflow outlet 10c). Figure 8 In the outflow piece 2c shown, the shape of the outflow port 10c is a shape that suppresses dripping, and the outer side of the outflow port 10c is subjected to an oil-repellent finish 14, so that the occurrence of dripping can be effectively suppressed.

[0058] In addition, in this embodiment, it is also possible to Fig. 9 As shown in the outflow member 2d, Figure 8 The lower side of the folded portion at the front end of the outflow piece 2c shown in the figure is subjected to an oil-repellent finish 14, and the upper side of the folded portion is also subjected to an oil-repellent finish 15. In addition, in this specification, the portion of the outflow port 10c subjected to the oil-repellent finish 15 may also be referred to as the inner side (inner periphery) of the outflow port 10c (that is, continuously connected to the inner side surface of the outflow port 10c). Fig. 9 In the outflow piece 2d shown, the shape of the outflow port 10c is a shape that suppresses dripping, and the outer side and the inner side of the outflow port 10c are respectively subjected to oil-repellent processing 14 and 15, so that the occurrence of dripping can be effectively suppressed.

[0059] In addition, in this embodiment, it is also possible to Fig.10 As shown in the outflow piece 2e, the shape of the outflow outlet 10e is set to a shape in which the edge of the front end of the outflow outlet 10e expands outward. In this case, as in Fig.10 As shown in the outflow piece 2e, the edge of the front end of the outflow port 10e is subjected to oil repellent processing 13e. That is, Fig.10 The structure of the outflow member 2e shown is similar to that of Figure 7 The structure corresponds to the structure in which the edge of the front end of the outflow outlet 10 of the outflow piece 2b is extended outward. Fig.10 As for the outflow piece 2e shown in the figure, the shape of the outflow port 10e is a shape that suppresses dripping, and the front end of the outflow port 10e is subjected to an oil-repellent process 13e, so that the occurrence of dripping can be effectively suppressed. Fig.10 In the outflow piece 2e shown, only the outer side may be subjected to oil repellent processing (with Figure 3 Corresponding to this), the outer side and top surface can also be treated with oil repellent (corresponding to Figure 6 correspond).

[0060] In addition, Figures 6 to 10 In the other configuration examples shown, at least the portion of the outflow port 10 through which the liquid passes when pouring the liquid may be subjected to an oleophobic treatment.

[0061] Other configuration examples of this embodiment will be further described.

[0062] Hereinafter, a structural example in which an oleophilic treatment is performed in addition to the oleophobic treatment will be described.

[0063] In this embodiment, it is also possible to Fig.11 As shown in the outflow piece 2f, the outer side of the outflow outlet 10 is subjected to an oil-repellent process 13f, and the inner side of the outflow outlet 10 is subjected to an oil-philic process 17f. By setting such a structure, it is possible to effectively suppress the occurrence of dripping. Here, the oil-philic process 17f is a process for improving the affinity with oil, in other words, a process for reducing the contact angle of oil, and can be implemented by, for example, applying an oil-philic agent to the surface of the outflow outlet 10.

[0064] Fig.12 It is used for illustration purposes Fig.11 A cross-sectional view of the outflow member of the structural example shown in FIG. Fig.12 As shown in the left figure, when using Fig.11 When the liquid 21 is poured out from the outflow port 10 by the outflow piece 2 f shown, the outer side of the outflow port 10 is subjected to the oil-repellent processing 13 f , so that the liquid 21 can be prevented from spreading and adhering to the outer side of the outflow port 10 .

[0065] Afterwards, if Fig.12As shown in the right figure of , when the outflow piece 2f is restored to verticality in order to stop the outflow of the liquid 21, the liquid 21 will gather in the portion where the lipophilic processing 17f is implemented (the inner side near the outlet of the outflow outlet 10). In other words, the portion where the lipophilic processing 17f is implemented has a higher affinity for the liquid 21, so the liquid 21 will gather in the portion where the lipophilic processing 17f is implemented. Therefore, when the outflow piece 2f is restored to verticality, the liquid present near the outlet of the outflow outlet 10 (especially the top surface) is pulled to the inside of the outflow outlet 10 (the liquid pulled to the inside is represented by the figure mark 22). Therefore, it is possible to prevent the liquid from remaining on the outside and top surface of the outflow outlet 10, and it is possible to effectively prevent dripping.

[0066] In addition, in this embodiment, the lipophilic processing can also be performed by forming at least one of a concave portion and a convex portion on the inner side near the outlet of the outlet 10. Figure 13A to Figure 13C As in the outflow piece 2g shown in FIG. 1 , the outer side of the outflow port 10 is subjected to an oil-repellent finish 13g, and at least one of the concave portion 31 and the convex portion 32 is formed inside the outflow port 10 to be subjected to an oleophilic finish. Fig.13A A configuration example in which a recessed portion 31 is formed inside the outlet 10 near the outlet is shown. Fig. 13B A configuration example in which a convex portion 32 is formed inside the outlet 10 near the outlet is shown. Fig. 13C A structural example in which a concave portion 31 and a convex portion 32 are formed inside the vicinity of the outlet of the pouring nozzle 10 is shown.

[0067] In this way, when at least one of the concave portion 31 and the convex portion 32 is formed inside the outlet of the outflow port 10, the liquid is pulled to the concave portion 31 and the convex portion 32 on the surface of the outflow port 10 due to the surface tension of the liquid, and the liquid stays in the concave portion 31 and the convex portion 32. Therefore, the inside of the outflow port 10 can be given lipophilicity.

[0068] also, FIG. 13A to FIG. 13C The structural example shown is only for illustration, and in the present embodiment, the number of the recessed parts 31 and the convex parts 32 to be formed can be arbitrarily determined. For example, when the outflow piece 2g is manufactured by injection molding, by using a mold having at least one of the recessed parts and the convex parts, at least one of the recessed parts and the convex parts can be formed inside the outflow port 10 when the outflow piece 2g is manufactured.

[0069] In addition, in this embodiment, it is also possible to Fig.14 As shown in the outflow piece 2h, the outer side of the outflow outlet 10 and the top surface of the outflow outlet 10 (the surface on the front end side of the outflow outlet 10) are subjected to oil repellent processing 13h, and the inner side of the outflow outlet 10 is subjected to oil-philic processing 17h. With such a structure, the occurrence of dripping can be effectively suppressed.

[0070] In addition, Figures 11 to 14 In the illustrated configuration example, at least the portion of the outflow port 10 through which the liquid passes when pouring the liquid may be subjected to an oleophobic finish or an oleophilic finish.

[0071] In addition, Fig.11 , Fig.14 In the structure shown (structure with lipophilic processing 17f, 17h), when the material constituting the outflow port 10 itself is a lipophilic material, the inner side of the outflow port 10 can be made lipophilic without performing the lipophilic processing 17f, 17h. In this case, it is not necessary to perform the lipophilic processing by coating or forming concavoconvexities. In the present invention, the lipophilic processing can be performed by using a lipophilic material as a raw material when manufacturing the outflow port 10. For example, plastic has hydrophobic and lipophilic properties. In addition, glass and paper have hydrophilic and lipophilic properties.

[0072] Next, other configuration examples of this embodiment will be further described.

[0073] Fig.15 It is a plan view showing another structural example of the outflow piece according to the present embodiment. Fig.16 yes Fig.15 A cross-sectional view of the outflow piece along the cutting line XVI-XVI is shown.

[0074] like Fig.15 , Fig.16 The outflow piece 202 shown in the figure includes a main body 210 and a cover 211. An outflow port 213 is provided inside the main body 210. An opening 219 is provided in the center of the outflow port 213. Fig.16 As shown in the cross-sectional view of FIG. 2 , the outflow port 213 has a shape in which the edge 214 of the front end expands outward (see FIG. 2 ). Figure 8 , Fig. 9 ). The liquid stored in the container body is poured out of the container through the opening 219 provided at the outflow port 213. Fig.16 2 shows a cross-sectional view of a state where the plug 220 is installed. When the outflow piece 202 is used, the plug 220 is pulled upward and removed, so that the inside of the container is connected to the outside through the opening 219.

[0075] like Fig.15 , Fig.16 As shown, the cover 211 is attached to the main body 210 via a hinge 212. That is, the cover 211 is rotatably attached to the main body 210 by the hinge 212, thereby enabling the upper surface of the main body 210 (outlet 213) to be opened and closed.

[0076] In addition, if Fig.15 , Fig.16The outflow piece 202 shown is provided with an inner cover 216 on the inner side of the cover body 211. The inner cover 216 is configured to abut against the outflow port 213 when the main body 210 is closed with the cover body 211. By setting such a structure, the opening 219 can be blocked with the inner cover 216. In addition, the outer periphery of the main body 210 is configured to be able to fit with the outer periphery of the cover body 211. Therefore, as shown in FIG. Fig.15 , Fig.16 The outflow piece 202 shown can plug both the inner side and the outer periphery of the main body 210 when the main body 210 is closed by the cover 211. Therefore, it is possible to effectively suppress the leakage of liquid from the opening 219 to the outside.

[0077] In addition, if Fig.15 , Fig.16 As shown, the outflow piece 202 has a groove 221 on the outside of the outflow port 213. The groove 221 has the following function: when pouring liquid from the outflow port 213, it receives the liquid dripping from the edge 214 of the front end of the outflow port 213 to the outside of the outflow port 213. Fig.16 213. The arrows in FIG. 21 indicate the flow of the liquid dripping from the edge 214 of the outflow port 213. In addition, the upper portion of the outer wall portion 224 of the groove portion 221 is configured to be inclined inward. Thus, when the outflow port 213 is inclined, it is possible to suppress the liquid from dripping from the groove portion 221 to the outside of the main body 210.

[0078] like Fig.17 As shown, the groove 221 is provided to surround the outer periphery of the outflow port 213. In addition, the groove 221 is configured to be connected to the opening 219 at the connection portion 222 on the hinge 212 side. Therefore, after the outflow port 213 is tilted to allow liquid to flow out of the outflow port 213, if the outflow port 213 is restored to a horizontal state, the liquid dripping from the edge 214 of the outflow port 213 will temporarily accumulate in the groove 221, and then flow through the groove 221 on the outer periphery of the outflow port 213 and flow toward the opening 219 through the connection portion 222. In addition, Fig.17 The hatched lines indicate where the liquid flows.

[0079] In addition, in Figures 15 to 17 In the outflow piece 202 shown, the groove 221 is subjected to an oil-repellent finish. For example, the groove 221 provided to surround the outer periphery of the outflow outlet 213 may be subjected to an oil-repellent finish at least at the position where the liquid passes. In addition, the groove 221 as a whole may be subjected to an oil-repellent finish. By thus performing the oil-repellent finish, the liquid accumulated in the groove 221 can be easily flowed in the groove 221 at the outer periphery of the outflow outlet 213. Therefore, the spilled liquid can be easily returned to the inside of the container via the groove 221. When performing the oil-repellent finish on the groove 221, the same method as the above-mentioned method can also be used.

[0080] In addition, in Figures 15 to 17 In the outflow piece 202 shown, the outlet 213 is also subjected to oleophobic processing (may also include oleophilic processing) as in other structural examples. Since the outlet 213 is subjected to oleophobic processing and oleophilic processing as in other structural examples, repeated description is omitted.

[0081] As mentioned above, the present invention has been described through the above-mentioned embodiments, but the present invention is not limited to the configurations of the above-mentioned embodiments, and naturally includes various modifications, corrections, and combinations that can be obtained by those skilled in the art within the scope of the invention of the claims of this application.

Claims

1. An outflow piece, which is mounted on a container body and has an outflow port for pouring out an oily liquid stored in the container body, wherein: The outer side of the outflow port is processed to be oleophobic at least at the outer side of the position through which the liquid passes when the liquid is poured out. The top surface of the outflow port is at least the top surface of the position where the liquid passes when the liquid is poured out, and is oleophobic. The inner side of the outflow port is processed to be lipophilic at least at the inner side of the position through which the liquid passes when the liquid is poured out. The structure is such that after pouring the liquid from the outflow port, when pouring the liquid is stopped and the outflow piece is restored to a vertical position, the liquid gathers at the portion subjected to the lipophilic treatment, and the liquid present near the outlet of the outflow port is pulled to the inside of the outflow port.

2. The outflow piece according to claim 1, characterized in that: The outflow port has a shape in which an edge of a front end of the outflow port expands outward and then turns back.

3. The outflow piece according to claim 1, characterized in that: The outflow port has a shape in which an edge of a front end of the outflow port expands outward.

4. The outflow piece according to claim 1, characterized in that: The lipophilic processing is performed by forming at least one of a concave portion and a convex portion inside the outflow port.

5. The outflow piece according to claim 1, characterized in that: An oleophobic material is used as a raw material when manufacturing the outflow piece, so that the surface of the outflow port is made oleophobic.

6. The outflow piece according to claim 1, characterized in that: The oil-repellent treatment is performed by applying an oil-repellent agent to the outflow port.

7. The outflow piece according to claim 1, characterized in that: The oil-repellent processing is performed by adding fine particles to the resin material which is the raw material of the outflow port.

8. The outflow piece according to claim 1, characterized in that: The outflow piece includes a groove portion, the groove portion being arranged to surround the outer periphery of the outflow port, The groove portion is configured to receive the liquid dripping along the outer side of the outflow port and return the received liquid to the container body through the groove portion. At least a portion of the groove where the liquid passes is subjected to an oil-repellent finish.

9. A container comprising: The outflow piece according to any one of claims 1 to 8; and A container body for storing the liquid.
