Detailed Description

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a side view of a container for illustrating an embodiment. As shown in fig. 1, a container 1 of the present embodiment includes an effusing material 2 and a container body 3 for storing liquid. The outflow member 2 is attached to the container body 3 and is used for pouring out the oily liquid stored in the container body 3.

The liquid stored in the container body 3 is an oily liquid. Here, the oily liquid refers to a liquid containing an oil component, such as an edible oil or a sauce. Examples of the edible oil include: 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 and the like. The present invention is not limited to this, and can be applied to any liquid as long as it is an oily liquid that is liquid at normal temperature. The present invention can also be applied to a viscous paste material (e.g., paste-like artificial butter).

The container body 3 can be configured using, for example, a resin container, a paper container, a glass container, or the like. As the material of the resin container, for example, polyolefin resin such as polypropylene and polyethylene, polyester resin such as polyethylene terephthalate, and the like can be used.

As shown in fig. 1, the spout 2 is attached to the upper portion of the container body 3. The outflow member 2 may be formed integrally with the container body 3. For example, in the case of the resin container 1, the effusing member 2 and the container body 3 may be integrally formed by molding using a mold having a shape in which the effusing member 2 and the container body 3 are integrated. The spout 2 may be configured to be separable from the container body 3. For example, after the liquid in the container 1 is used, the effusing material 2 (e.g., plastic) may be separated from the container body 3 (e.g., paper or glass) and may be discarded separately.

Fig. 2 is a side view for explaining the outflow member of the present embodiment. Fig. 3 is a sectional view and a plan view showing the spout of the present embodiment. In fig. 3, the cover 11 is not shown. The same applies to fig. 4 to 14 described later.

As shown in fig. 2, the spout 2 of the present embodiment includes a spout 10 and a lid 11. As shown in fig. 3, the outlet 10 is a cylindrical structure having an opening 19 therein. The oily liquid stored in the container body 3 is poured out of the container 1 through the opening 19 provided in the spout 10. As shown in fig. 2, the lid 11 is attached to the spout 10 via a hinge 12. That is, the lid 11 is attached to the spout 10 in a rotatable state by the hinge 12, and thereby the upper surface of the spout 10 can be opened and closed. Fig. 1 shows a state in which the outflow port 10 is closed, and fig. 2 shows a state in which the outflow port 10 is opened.

Although fig. 1 and 2 show a configuration example in which the lid 11 is attached to the spout 10 via the hinge 12, the lid 11 may be screwed into the spout 10 in this embodiment. In this case, the lid 11 can be removed from the spout 10 or the spout can be covered with the lid 11 by rotating the lid 11. Although fig. 2 and 3 illustrate the case where the outlet 10 has a cylindrical shape, the outlet 10 may have a shape other than a cylindrical shape in the present embodiment. For example, the shape of the outlet 10 in plan view may be an ellipse or a polygon such as a quadrangle.

In the present embodiment, as shown in fig. 2 and 3, the oil-repellent treatment 13 is performed outside the spout 10. By thus applying the oil-repellent finish 13 to the outside of the spout 10, it is possible to suppress the occurrence of dripping when the oily liquid is poured out. In fig. 3, the portion of the surface of the spout 10 to which the oil-repellent treatment 13 is applied is shown to be thick in order to clearly show the position of the oil-repellent treatment 13, but the portion to which the oil-repellent treatment 13 is applied is actually configured to be thin relative to the surface of the spout 10.

Fig. 5 is a sectional view for explaining a state where a liquid is poured out using a prior art spout. As shown in the left side of fig. 5, when pouring out the liquid 121 from the spout 110 using the spout 102 of the related art, the liquid 121 is poured out in a state where a part of the liquid 121 spreads outside the spout 110 (a part where the liquid spreads is indicated by a reference numeral 122).

Thereafter, as shown in the right drawing of fig. 5, when the outflow member 102 is returned to the vertical state 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 on the outside of the outflow member 102, and the remaining liquid 123 flows to the outside of the outflow member 102 (container) and is dripped. Such dripping occurs particularly in the case of a liquid having a high viscosity such as an oily liquid.

In contrast, in the invention of the present embodiment, as shown in fig. 2 and 3, since the oil-repellent treatment 13 is performed outside the spout 10, it is possible to suppress the occurrence of dripping when the oily liquid is poured out. Hereinafter, the details will be described with reference to fig. 4.

Fig. 4 is a sectional view for explaining a case where the spout of the present embodiment is used to pour out a liquid. As shown in the left side of fig. 4, when the liquid 21 is poured from the outflow port 10 using the effusing piece 2 of the present embodiment, since the oil-repellent processing 13 is performed on the outside of the outflow port 10, it is possible to suppress a part of the liquid 21 from spreading to the outside of the outflow port 10. That is, when the oil-repellent treatment 13 is performed on the outside of the outflow port 10, the liquid 21 can be prevented from adhering to the outside of the outflow port 10 by the oil-repellent treatment 13. Therefore, a part of the liquid 21 can be suppressed from spreading to the outside of the outflow port 10.

As described above, in the present embodiment, since it is possible to suppress a part of the liquid 21 from spreading to the outside of the spout 10, it is possible to suppress dripping when the spout 2 is returned to the vertical state in order to stop the discharge of the liquid 21, as shown in the right drawing of fig. 4. That is, in the present embodiment, since the oil-repellent treatment 13 is performed on the outer side of the outflow port 10, the liquid 22 can be prevented from remaining on the outer side of the outflow port 10. Therefore, the occurrence of dripping can be suppressed.

Although fig. 1 shows an example in which the spout 2 is attached to the upper portion of the container body 3, in the present embodiment, the spout may be attached to the inclined surface of a paper container having an inclined surface on the upper portion of the container body (that is, a paper container having a roof shape on the upper portion). When the spout 2 is attached to the slope of the container having a roof shape in this way, the opening of the spout 2 is not horizontal in a state where the container body is placed, and therefore, the spout is easily dropped. In particular, when the liquid contained in the container body is nearly full, the liquid is poured from the spout 2 by tilting the container slightly, and therefore, the liquid is easily dripped. Therefore, the effect of the present invention is particularly remarkable when the spout 2 of the present embodiment is attached to the slope of such a container having a roof shape.

In fig. 2 to 4, the example in which the oil-repellent treatment 13 is performed on the entire periphery of the outside of the spout 10 is shown, but in the present embodiment, the oil-repellent treatment may be performed on the outside of the spout 10 at least outside the position where the liquid passes when the liquid 21 is poured. For example, the oil-repellent treatment 13 may be performed on the half of the outer periphery of the spout 10 on the side through which the liquid 21 is poured.

In the present embodiment, the oil-repellent processing 13 is processing for repelling oil, in other words, processing for increasing the contact angle of oil, and may be performed by applying an oil-repellent agent to the surface of the spout 10, for example. For example, among the oleophobic agents that can be used are: fluorine-based oil-repellent agents, silicone-based oil-repellent agents, teflon-based oil-repellent agents, and the like.

In the present embodiment, the oil-repellent processing 13 may be performed by adding fine particles to a resin material that is a raw material of the spout 10. By adding fine particles to the resin material that is the raw material of the spout 10 in this manner, irregularities can be formed on the surface of the spout 10 after molding, and oil repellency can be imparted. For example, inorganic materials such as metal oxides (e.g., silica, alumina, etc.) and organic materials such as cured resin products can be used as the fine particles. The particle size of the fine particles is not particularly limited as long as the fine particles can impart oil repellency, and may be, for example, 5 μm to 100 μm.

According to the invention of the present embodiment described above, it is possible to provide a spout and a container that can suppress dripping when an oily liquid is poured out.

Next, another configuration example of the outlet according to the present embodiment will be described.

In the present embodiment, as in the spout 2a shown in fig. 6, the outer side of the spout 10 and the top surface of the spout 10 (the surface on the tip side of the spout 10) may be subjected to oil-repellent processing 13a. By thus performing the oil-repellent treatment 13a also on the top surface of the outflow port 10, it is possible to suppress the liquid from adhering to the top surface of the outflow port 10, and to effectively suppress the occurrence of dripping.

In the present embodiment, as in the spout 2b shown in fig. 7, the oil-repellent processing 13b may be performed on the outside of the spout 10, the top surface of the spout 10 (the surface on the tip side of the spout 10), and the inside of the spout 10. By thus performing the oil-repellent treatment 13b also on the inside of the outflow port 10, it is possible to suppress the liquid from adhering to the inside of the outflow port 10, and to effectively suppress the occurrence of dripping.

For example, in the present embodiment, the entire surface of the outflow port 10 may be subjected to the oil-repellent treatment 13b. For example, by using an oil-repellent material as a raw material in manufacturing the outlet 2b, the entire surface of the outlet 10 after manufacturing can be made oil-repellent. The outflow material 2b is made of, for example, silicone resin, and the entire surface of the outflow port 10 can be rendered oil-repellent.

In the present embodiment, the outside and the inside of the spout 10 (except for the top surface of the spout 10) may be subjected to oil repellent processing (not shown).

In the present embodiment, as in the outlet 2c shown in fig. 8, the shape of the outlet 10c may be such that the edge of the tip of the outlet 10c is extended outward and then folded back. In this case, as in the spout 2c shown in fig. 8, the oil-repellent processing 14 is performed on the lower side of the folded portion at the tip of the spout 10 c. In the present specification, the portion of the outlet port 10c to which the oil-repellent treatment 14 is applied may be expressed as the outer side (outer periphery) of the outlet port 10c (that is, continuously connected to the outer surface of the outlet port 10 c). In the outflow tool 2c shown in fig. 8, the shape of the outflow port 10c is a shape that suppresses dripping, and further, since the oil-repellent processing 14 is performed on the outer side of the outflow port 10c, the occurrence of dripping can be effectively suppressed.

In the present embodiment, as in the spout 2d shown in fig. 9, the oil-repellent processing 14 may be performed on the lower side of the folded portion of the tip of the spout 2c shown in fig. 8, and the oil-repellent processing 15 may be performed on the upper side of the folded portion. In the present specification, the portion of the outlet port 10c subjected to the oil-repellent treatment 15 may be expressed as the inner side (inner circumference) of the outlet port 10c (that is, continuously connected to the inner surface of the outlet port 10 c). In the outlet 2d shown in fig. 9, the shape of the outlet 10c is a shape that suppresses dripping, and the outer side and the inner side of the outlet 10c are subjected to oil-

repellent processing

14 and 15, respectively, so that dripping can be effectively suppressed.

In the present embodiment, the shape of the outlet port 10e may be such that the edge of the tip of the outlet port 10e is extended outward, as in the case of the outlet material 2e shown in fig. 10. In this case, as in the case of the outlet 2e shown in fig. 10, the edge of the tip of the outflow port 10e is subjected to oil-repellent processing 13e. That is, the configuration of the spout 2e shown in fig. 10 corresponds to the configuration in which the edge of the tip of the spout 10 of the spout 2b shown in fig. 7 is expanded outward. In the spout 2e shown in fig. 10, the spout 10e is shaped to suppress dripping, and the front end of the spout 10e is given the oil-repellent finish 13e, so that dripping can be effectively suppressed. In the pouring member 2e shown in fig. 10, only the outer side may be subjected to the oil-repellent processing (corresponding to fig. 3), or the outer side and the top surface may be subjected to the oil-repellent processing (corresponding to fig. 6).

In other configuration examples shown in fig. 6 to 10, at least a position of the outlet port 10 through which the liquid passes when the liquid is poured may be subjected to oil-repellent processing.

Another configuration example of the present embodiment will be further described.

An example of a structure in which oleophilic processing is performed in addition to oil repellent processing will be described below.

In the present embodiment, as in the outflow material 2f shown in fig. 11, the oil-repellent finish 13f may be applied to the outside of the spout 10, and the oleophilic finish 17f may be applied to the inside of the spout 10. With such a configuration, occurrence of dripping can be effectively suppressed. Here, the lipophilic finish 17f is a finish for improving the wettability with the oil, in other words, a finish for reducing the contact angle of the oil, and may be performed by applying a lipophilic agent to the surface of the spout 10, for example.

Fig. 12 is a sectional view for explaining a state where liquid is poured out by using the spout of the configuration example shown in fig. 11. As shown in the left side of fig. 12, when the liquid 21 is poured out from the outflow port 10 using the outflow tool 2f shown in fig. 11, the liquid 21 is prevented from spreading and adhering to the outside of the outflow port 10 because the oil-repellent treatment 13f is performed on the outside of the outflow port 10.

Thereafter, as shown in the right drawing of fig. 12, when the outflow piece 2f is returned to be vertical in order to stop the outflow of the liquid 21, the liquid 21 is gathered at the portion where the lipophilic finish 17f is applied (inside in the vicinity of the outlet of the outflow port 10). That is, since the portion subjected to oleophilic treatment 17f has high wettability with respect to liquid 21, liquid 21 is gathered in the portion subjected to oleophilic treatment 17f. Therefore, when the outflow piece 2f is returned to be vertical, the liquid existing in the vicinity of the outlet of the outflow port 10 (particularly, the top surface) is pulled to the inside of the outflow port 10 (the liquid pulled to the inside is denoted by reference numeral 22). Therefore, the liquid can be prevented from remaining on the outer side and the top surface of the spout 10, and the occurrence of dripping can be effectively prevented.

In the present embodiment, at least one of the concave portion and the convex portion may be formed inside the vicinity of the outlet of the spout 10 to perform oleophilic processing. That is, as in the flow-out member 2g shown in fig. 13, the oil-repellent processing 13g may be performed on the outer side of the flow-out port 10, and the oleophilic processing may be performed by forming at least one of the concave portion 31 and the convex portion 32 on the inner side of the flow-out port 10. Fig. 13A shows a configuration example in which a concave portion 31 is formed inside the vicinity of the outlet of the spout 10. Fig. 13B shows a configuration example in which the protrusion 32 is formed inside the vicinity of the outlet of the spout 10. Fig. 13C shows a configuration example in which a concave portion 31 and a convex portion 32 are formed inside the vicinity of the outlet of the spout 10.

In this way, when at least one of the concave portion 31 and the convex portion 32 is formed inside the vicinity of the outlet of the spout 10, the liquid is pulled to the concave portion 31 and the convex portion 32 of the surface of the spout 10 due to the surface tension of the liquid, and the liquid remains in the concave portion 31 and the convex portion 32. Therefore, lipophilicity can be imparted to the inside of the spout 10.

Note that the configuration examples shown in fig. 13A to 13C are merely illustrative, and the number of the concave portions 31 and the convex portions 32 to be formed can be arbitrarily determined in the present embodiment. For example, when the outlet 2g is manufactured by injection molding, at least one of the concave portion and the convex portion can be formed inside the outlet 10 when the outlet 2g is manufactured by using a mold having at least one of the concave portion and the convex portion.

In the present embodiment, as in the outlet 2h shown in fig. 14, the outer side of the spout 10 and the top surface of the spout 10 (the surface on the tip side of the spout 10) may be subjected to oil repellent processing 13h, and the inner side of the spout 10 may be subjected to oleophilic processing 17h. With such a configuration, the occurrence of dripping can be effectively suppressed.

In the configuration examples shown in fig. 11 to 14, at least the position of the outlet port 10 through which the liquid passes when the liquid is poured may be subjected to oil-repellent processing or oleophilic processing.

In the structure shown in fig. 11 and 14 (structure including the

lipophilic processes

17f and 17 h), when the material itself constituting the outflow port 10 is a lipophilic material, the inside of the outflow port 10 can be made lipophilic without performing the

lipophilic processes

17f and 17h. In this case, it is not necessary to perform oleophilic processing by coating or forming irregularities. In the present invention, oleophilic processing can be performed by using an oleophilic material as described above as a raw material in the production of the spout 10. For example, plastics are hydrophobic and oleophilic. In addition, glass and paper have lipophilicity.

Next, another configuration example of the present embodiment will be further described.

Fig. 15 is a plan view showing another configuration example of the effusing member of the present embodiment. Fig. 16 is a cross-sectional view of the outflow part shown in fig. 15, taken along section line XVI-XVI.

The spout 202 shown in fig. 15 and 16 includes a main body 210 and a cover 211. An outlet 213 is provided inside the body 210. An opening 219 is provided at the center of the outlet 213. As shown in the cross-sectional view of fig. 16, the outflow port 213 has a shape in which a front edge 214 expands outward (see fig. 8 and 9). The liquid stored in the container body is poured out of the container through an opening 219 provided in the spout 213. Fig. 16 is a sectional view showing a state where the plug 220 is attached. When the spout 202 is used, the stopper 220 is pulled upward and removed, whereby the container interior is connected to the outside through the opening 219.

As shown in fig. 15 and 16, the cover 211 is attached to the main body 210 via a hinge 212. That is, the lid 211 is attached to the body 210 by the hinge 212 in a turnable manner, whereby the upper surface of the body 210 (the outlet 213) can be opened and closed.

As shown in fig. 15 and 16, the spout 202 has an inner cover 216 provided inside the cover 211. The inner lid 216 is configured to abut against the outlet 213 when the body 210 is closed by the lid 211. With such a configuration, the opening 219 can be closed by the inner lid 216. The outer periphery of main body 210 is configured to be fittable to the outer periphery of cover 211. Therefore, in the spout 202 shown in fig. 15 and 16, when the main body portion 210 is closed by the cover 211, the plug can be inserted into both the inner side and the outer periphery of the main body portion 210. Therefore, leakage of the liquid from the opening 219 to the outside can be effectively suppressed.

As shown in fig. 15 and 16, the outflow member 202 has a groove 221 outside the outflow port 213. The groove 221 has the following functions: when pouring the liquid from the spout 213, the liquid dripped from the edge 214 at the tip of the spout 213 to the outside of the spout 213 is received. The flow of the liquid dripped from the edge 214 of the outflow port 213 is indicated by arrows in fig. 16. The upper portion of the outer wall 224 of the groove 221 is inclined inward. This can prevent liquid from dripping from groove 221 to the outside of main body 210 when outlet 213 is inclined.

As shown in fig. 17, the groove 221 is provided to surround the outer periphery of the outflow port 213. The groove 221 is connected to the opening 219 at a connection portion 222 on the hinge 212 side. Therefore, if the outflow port 213 is returned to the horizontal position after the outflow port 213 is tilted to cause the liquid to flow out from the outflow port 213, the liquid dripped from the edge 214 of the outflow port 213 temporarily accumulates in the groove 221, and thereafter flows through the groove 221 on the outer periphery of the outflow port 213 and flows toward the opening 219 via the connection portion 222. In fig. 17, the liquid flow portion is indicated by hatching.

In the pouring material 202 shown in fig. 15 to 17, the groove portion 221 is subjected to oil-repellent processing. For example, at least the position of the groove 221 provided to surround the outer periphery of the outlet port 213 where the liquid passes may be subjected to oil repellent processing. Further, the groove portion 221 may be entirely subjected to oil repellent processing. By performing the oil-repellent processing in this manner, the liquid accumulated in the groove 221 can be made to easily flow through the groove 221 on the outer periphery of the outflow port 213. Therefore, the dripped liquid can be easily returned to the container through the groove 221. The groove portion 221 can be subjected to oil repellent processing by the same method as described above.

In the outflow tool 202 shown in fig. 15 to 17, the outflow port 213 is also subjected to oil-repellent processing (may include oleophilic processing) in the same manner as in the other configuration examples. Since the convection outlet 213 is subjected to the oil-repellent treatment and the oleophilic treatment, the same as in the other configuration examples, the description thereof will be omitted.

The present invention has been described above with reference to the above embodiments, but the present invention is not limited to the configurations of the above embodiments, and it is needless to say that 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 the present application are included.
