本発明は、油脂を充填した容器から該油脂を注ぎ出す際、該油脂の吹き出し（液吹き）

The present invention is directed to preventing the spraying (liquid spraying) of oil and fat when the oil and fat are poured out from a container filled with the oil and fat.
The present invention relates to a spout for a grease container that can suppress the above-mentioned problem.

In recent years, there has been a shift to more environmentally friendly products in the field of food and beverage packaging. For example, efforts are underway to significantly reduce the amount of plastic used by switching from plastic containers to paper containers, thereby reducing plastic waste and garbage volume, and ultimately CO2 emissions.

On the other hand, containers have been known in the past in which a cap with a pouring tube is attached to the opening of the container to make it easier to pour out the liquid contents from the container, and in such capped containers with pouring tubes, it is generally desired that the liquid contents drip little and drain easily.
When the liquid contents filled into such a container equipped with a dispensing tube are relatively viscous, such as cosmetics such as emulsion, or oil, dressing, or sauce, the liquid does not drain well after pouring out, and the liquid contents tend to remain in the dispensing tube, causing dripping. For this reason, various designs for the dispensing tube and cap have been considered, or so-called squeeze bottles, which use flexible plastic containers for the container body, are used, and after the contents are pushed out by squeezing the container, the suction force (suck back) that occurs when the container returns to its original shape is used to pull the residue in the dispensing tube back into the container, thereby preventing dripping.

For example, a cap for a liquid container has been disclosed in which the inner diameter of the nozzle portion is locally narrowed to prevent dripping from a liquid container filled with lotion such as emulsion (Patent Document 1).
Furthermore, for example, a dispensing cap has been disclosed that has a flange piece with a predetermined width at the top end of a dispensing tube of a predetermined height, and a straightening tube at the entrance of the dispensing passage formed by the dispensing tube, in order to improve liquid drainage and prevent discomfort and stains caused by dripping, even when the contents are relatively viscous, such as hair treatment oil (Patent Document 2).
Furthermore, a dispensing cap has been disclosed that prevents dripping and soiling of the dispensing tube even when dispensing highly viscous liquid contents such as thick sauce by configuring the communicating hole of the dispensing tube to have a straight section and an enlarged diameter section (Patent Document 3).

As mentioned above, in products in which a capped container equipped with a dispensing tube is filled with a relatively viscous liquid content such as oil, various studies have been conducted on the shapes of the dispensing tube, cap body, etc. to ensure that the liquid content drains easily after being dispensed and to prevent dripping.
While investigating problems such as dripping of oils and fats, the inventors first noticed a phenomenon in which oils and fats spurt out of the spout when pouring begins. Upon further investigation into this spurting phenomenon, they confirmed that, for example, if the container body is made of a relatively soft material such as soft plastic or a paper pack, the container is crushed when held by hand, thereby forcing out the air present inside the container, and that the spurted air also pushes out any oil or fat remaining in the flow path of the spout, resulting in the spurting phenomenon.
The inventors have discovered that in a cap provided with a pouring tube (spout), if the inner peripheral surface of the pouring tube has a step of a predetermined size or greater, the step will cause a liquid pool of oil and fat, which is one of the causes of the aforementioned blowing-out phenomenon. The step on the inner peripheral surface of the pouring tube can be generated when the pouring tube is molded using a mold, but the inventors have discovered that by keeping this step within a predetermined range, the occurrence of a liquid pool of oil and fat can be prevented, and as a result, the blowing-out phenomenon can be suppressed.

To clarify the effects of the present invention, a comparative example of a cap different from the present invention, particularly a cap with a different spout configuration, is shown in Figure 3. Figure 3 is an enlarged cross-sectional view of the spout of the comparative example, corresponding to Figure 2, which is an enlarged cross-sectional view of the spout 22.
As shown in Figure 3, in the comparative embodiment, spout 92 is a cylinder that communicates with the upper opening of a container (not shown) via opening 91A formed on the underside of top wall 91, and inner surface 920 of spout 92 has a spatial structure formed by a cylinder 920A that extends vertically to opening 91A from the downstream side in the flow direction of the grease, and a truncated cone 920C that expands in diameter from the upstream end of cylinder 920A to the periphery 91B of opening 91A.
Here, a step 922 formed by the step between the cylinder 920A and the truncated cone 920C in the comparative embodiment will be compared with a step 222 formed by the step between the first cylinder 220A and the second cylinder 220B in the embodiment of the present invention shown in FIG.
The diameter D 220A4 of the upstream end 220A4 of the second cylinder 220B according to the present invention is the same as the diameter D 920A4 of the upstream end 920A4 of the cylindrical column 920A of the comparative example, and the diameter D 220B2 of the downstream end 220B2 of the cylindrical column 220B according to the present invention is the same as the diameter D 220B2 of the downstream end 920B2 of the cylindrical column 920C of the comparative example.
Even if the diameters D 920C2 of the step portion 222 of the present invention are the same, the amount of liquid that can be stored in the step portions of both the step portions is smaller in the step portion 222 of the present invention.
That is, in the present invention, the structure (flow path) of the inner peripheral surface 220 of the spout 22 is the space formed by the first cylinder 220A, the second cylinder 220B, and the truncated cone 220C described above, and further, the difference in diameter between the first cylinder 220A and the second cylinder 220B at the connecting portion is set to 0.
By setting the step to a value between 0.05 mm and 0.5 mm, the step on the inner surface 220 of the spout 22 is kept within a specified range, thereby preventing the accumulation of grease in the step portion 222 and suppressing the grease blowing out phenomenon, i.e., oil spraying.

As shown in FIG. 3, in the comparative example, an opening 21A formed on the lower surface of the top wall 91
A downwardly protruding flow straightening portion 93 is provided at the peripheral edge 912 of the top wall 91. A step 914 formed between the flow straightening portion 93 and the lower surface of the top wall 91 can accumulate liquid or air.
On the other hand, in the present invention, by not installing the straightening section as shown in Figure 2, it is possible to suppress the entrainment of air that enters from the outside or remains inside the container when pouring out the oil or fat, thereby achieving smooth pouring of the oil or fat.

Next, the oil Lc is poured into the container 10 equipped with the cap 1 having the spout 22 of the present invention.
This section explains examples of how to use products filled with this ingredient.
5A and 5B are enlarged cross-sectional views of the periphery of the cap 1 in a product in which the container 10 fitted with the cap 1 is filled with the grease Lc.
Figure 5(b) shows the state in which the container 10 is further tilted and the oil Lc is poured out, Figure 5(c) shows the state in which the container 10 is slightly tilted back after pouring, and Figure 5(d) shows the state in which the container 10 is tilted back to its initial state.
As shown in Figures 5(a) to 5(d), the container 10 comprises a container body 5, a resin inner lid 51 connected to the container body 5, and a cap 1 attached to the upper opening 10A of the container 10, and the cap 1 and the inner lid 51 are configured to engage with each other (see Figure 5(d), etc.).
.
When using the product, the product is tilted (FIGS. 5(a) and (b)) and, if necessary, the container body 5 is squeezed (compressed), so that the oil Lc is poured out through the upper opening 10A of the container 10, the opening 21A provided in the top wall 21 of the cap 1, and the spout 22 of the cap 1 (FIG. 5(b)).
After using the product, when the product is returned to its position as shown in FIG. 5(c), the oil Lc remaining inside the spout 22 is returned by its own weight into the container through the opening 21A and the upper opening 10A.
In addition, when the oil Lc is pushed out by squeezing (compressing) the container body 5,
When the spout 22 is restored to its original shape, the suction force (suck back) causes the grease Lc remaining in the spout 22 to be pulled back into the container. At this time, the difference in diameter between the diameter D220A4 of the upstream end of the first cylinder 220A of the spout 22 and the diameter D220B2 of the downstream end of the second cylinder 220B is set to 0.05 mm or more and less than 0.5 mm, so that the grease Lc is not drawn back into the container.
The oil and fat Lc does not accumulate in the spout 22, and when the container 10 is crushed the next time it is held by hand and the air inside the container is pushed out from the spout 22, the oil and fat Lc can be prevented from being blown out.
