Description

The present invention relates to a container.

Conventionally, container shapes have been proposed for containers that hold edible oil as a content, and are designed to make the content easier to pour (see, for example, Patent Documents 1 and 2).

For example, the container in Patent Document 1 is proposed as a plastic container with a handle that is compact without reducing the container volume, even for large-capacity containers with a handle, while still maintaining ease of holding and pouring. This container is a plastic container for storing edible oil, etc., and has a recess for gripping formed on the opposing surface of the container body, and multiple annular ribs formed below the recess. It is said that by gripping the recess for gripping, it becomes easier to pour the contents.

The container in Patent Document 2 is proposed as a container that can optimize the pouring state of the contents. This container is a plastic container for storing edible oil and the like, and is composed of a mouth, a shoulder, and a body, with the mouth and shoulder inclined relative to the center line of the body. This allows the contents to be poured with less tilt, making the contents easier to pour, and also reduces the effects of pulsation when pouring the contents, making it easier to pour.

Containers that contain edible oil or the like are often turned upside down to drain the oil, as the oil does not drain easily. The container mouth is turned downwards to drain the last of the oil, but the optimal angle of inclination of the container mouth has not been thoroughly considered in the past. As a result, there has been a problem in that the container does not have a guide means for guiding the container mouth to the optimal angle of inclination.

Therefore, the object of the present invention is to provide a container having a guide means suitable for completely emptying the contents from the container opening.

[1] The present invention provides a storage container having a container body portion for storing contents therein, and a container mouth portion provided at an upper portion of the container body portion and for discharging the contents,
The container body is provided with a guiding means for guiding the container body to a predetermined inclination angle when the content is discharged.
[2] The guiding means may be a display unit that is attached to the container body and is composed of one or more selected from lines, letters, pictures, or figures, and the display unit may be configured to display in a manner that is easily visible when the container body is at the specified inclination angle when the contents are ejected.
[3] The display unit may be a label attached to the surface of the container body.
[4] The guiding means may be a handle portion such as a handle hole, knob, or recess provided in the container body portion, and when the handle portion is held to eject the contents from the container mouth portion, the container body portion may be configured to be at the predetermined inclination angle due to the action of gravity.
[5] The content may be edible oil.
[6] The storage container may be a storage container selected from a bottle, a pillow container, and a can container.
[7] The inclination angle of the container body may be within an angle range of 150° to 165° when the container mouth is in a vertically downward direction from an upward direction during the ejection.

The container of the present invention makes it possible to provide a container having a guide means suitable for completely discharging the contents from the container mouth.

[First embodiment of the present invention]
The container 1 according to the first embodiment of the present invention is a container having a container body 10 for storing contents therein and a container mouth 20 provided on the upper part of the container body 10 for discharging the contents, and the container body 10 is configured to have an guiding means for guiding the container body 10 to a predetermined inclination angle when discharging the contents. In the first embodiment, the guiding means is a visually acting indicator, for example, an indicator that is formed as a line, a character, a character string, a picture, a figure, or a combination of these, attached to the container body 10, and the indicator is configured to be easily visible when the container body 10 is at a predetermined inclination angle when discharging the contents. The indicator may be printed and/or molded on the container body 10, or may be attached to the container body 10 by a label or the like. In addition, it is preferable that the indicator is displayed on a surface where the widest area of the container side surface can be seen.

That is, in the first embodiment, when the contents are dispensed, the visual and psychological effects are utilized in that the lines, letters, character strings, pictures, figures, etc., attached to the container body 10 as the guiding means are tilted at an angle that is easy for the user to see. For example, when the inclination angle θ of the container body 10 becomes a predetermined inclination angle, the lines, letters, character strings, pictures, figures, etc., attached to the container body 10, or a display portion that is a combination of these, have a visual effect that makes the user feel that they are vertical or horizontal (perpendicular to the vertical). As a result, when the inclination angle θ of the container body 10 becomes a predetermined inclination angle, a usage state suitable for dispensing all the contents from the container mouth 20 becomes possible.

The guide means may be attached to the container body 10 in such a manner that lines, letters, character strings, pictures, figures, etc. are directly formed on the outer wall 10a of the container body 10 by printing, molding, etc., or a label, film, etc. with lines, letters, character strings, pictures, figures, etc. attached thereto may be attached to the outer wall 10a of the container body.

Figure 1(a) is a front view showing a state in which a container according to the first embodiment is placed on a floor surface, and Figure 1(b) is a front view showing a state in which the container mouth is tilted downward by an angle θ when dispensing the contents from the container mouth.

In FIG. 1(a), the container 1 is usually placed on the floor surface 500 with the container bottom 15 in contact with it, and in this state, the container mouth is facing upward. As shown in FIG. 1(a), the container 1 is usually placed on the floor surface 500 with the container bottom 15 in contact with it.

The center of the container bottom 15 is defined as point R, the horizontal direction of the floor surface 500 is defined as the x direction, and the x axis is defined as 51. The vertical upward direction is defined as the z direction, and the z axis is defined as 52. The central axis of the container 1, which passes through point R, is defined as 53.

As shown in FIG. 1(b), when the contents contained inside the container body 10 of the container 1 are to be discharged from the container mouth 20, the container body 10 is held, for example, with the fingers, and the container mouth 20 is oriented downward (direction A). At this time, the angle that the central axis 53 of the container 1 makes with the z-axis 52 is defined as the inclination angle θ of the container. As shown in FIG. 1(b), the inclination angle θ is defined based on the z-direction, which is the vertically upward direction. The unit of the inclination angle θ is ° (= deg). Therefore, when the container mouth 20 faces directly upward, the inclination angle θ = 0°, and when it faces directly downward, the inclination angle θ = 180°.

The specified tilt angle θ, which will be described in detail later, is an angle suitable for expelling the contents from the container mouth 20, and is particularly suitable for expelling the last few drops of the contents.

On the other hand, as shown in FIG. 1(a), the container 1 is usually placed on the floor surface 500 with the container bottom 15 in contact with it. The z-axis 52 in the z-direction coincides with the central axis 53 of the container 1. Here, as shown in FIG. 1(a), a line segment at an angle of (180°-θ) from the z-axis 52 is defined as the guiding line 54. For example, the line 31 as the guiding means is formed on the container body 10 so as to be perpendicular to this guiding line 54. When the contents are discharged from the container mouth 20, the container 1 is tilted so that this line 31 is horizontal as shown in FIG. 1(b), so that the container body 10 is at a predetermined tilt angle θ when the contents are discharged.

For example, when the tilt angle θ is 160°, in FIG. 1(a), the line 31 as the guiding means is a line at an angle of 20° perpendicular to the guiding line 54, and in FIG. 1(b), when the tilt angle θ is a predetermined angle of 160°, the line 31 as the guiding means appears horizontal. When a user holds the container 1, for example with the fingers, and expels the contents of the container 1 from the container mouth 20, the container 1 is tilted so that the line 31 is horizontal, and the container mouth 20 of the container 1 is guided downward to the predetermined tilt angle θ. This makes it easier to dispense the contents of the container 1 down to the last few drops.

Figure 2(a) is a cross-sectional view of Figure 1(a), and Figure 2(b) is a cross-sectional view of Figure 1(b), showing the state in which the oil content flows down the inner wall and out of the container mouth.

As shown in FIG. 2(a), the container 1 is in the shape of a bottle having an internal space for accommodating, for example, edible oil 70 as the contents, and is placed with the container bottom 15 in contact with the floor surface 500. In addition to edible oil 70, the contents can be liquids such as water, juice, and other drinking water, as well as oils (fats) that are liquid at room temperature, including edible oil.

In this embodiment, the container 1 is a plastic container such as a polyethylene container, a polypropylene container, a polyethylene terephthalate container, or a polylactic acid container. It can also be applied to glass containers, ceramic containers, metal (can) containers, and paper containers.

As shown in FIG. 2(b), the container 1 is held with fingers or the like and tilted to eject the contents (edible oil 70) from the container mouth 20. At this time, when the content (edible oil 70) is low in amount, oil droplets 71 are ejected from the container mouth 20, running from the bottom 10c inside the container along the inner wall 10b. In the case of viscous contents such as edible oil 70, when the content is low in amount, the oil droplets 71 are ejected from the container mouth 20, running from the bottom 10c inside the container along the inner wall 10b, as described above, instead of falling downward from the bottom 10c inside the container.

The inventors discovered that the contents can be ejected more efficiently when the container mouth 20 is tilted downward at a certain angle, i.e., the above-mentioned predetermined tilt angle θ, rather than facing straight down (tilt angle θ = 180°). In particular, when the contents are viscous oil such as edible oil 70, the inventors discovered that the remaining few drops can be ejected more efficiently.

Figure 3 is a graph plotting the relationship between time and the amount of oil remaining in the container, with the horizontal axis representing the time since the container was tilted and the vertical axis representing the amount of oil remaining in the container, and the container tilt angle θ being set as a parameter at 5° intervals from 150° to 180°. Figure 4 is a table showing the correlation between the amount of oil discharged and whether or not the container was shaken.

As shown in Figure 3, we evaluated the effect of different tilt angles θ of the container 1 on the amount of residual oil. This was done using the following methods (1) to (4).

(1) To prepare container 1, a PET container having an internal volume of 600 g is filled with approximately 15 g of edible oil, and the weight of the edible oil is accurately weighed.
(2) Tilt to the desired tilt angle θ in one second, and set the time when it is fully tilted to 0 seconds.
(3) From 15 seconds onwards, record the amount of oil discharged every 5 seconds.
(4) The difference between the amount of oil put into container 1 in (1) and the amount of oil discharged is defined as the amount of oil remaining in the container.

The following results were obtained from the graph shown in Figure 3. As for the effect of differences in tilt angle θ on the amount of residual oil, as shown in Figure 3, it became clear that the amount of residual oil is minimized by tilting the container 1 to 160° to 165° within 30 seconds after tilting, and by tilting it to 150° to 165° when it is fixed for 45 seconds or more.

In order to reduce the amount of oil remaining in the container, container 1 may be shaken up and down. Next, as shown in Figure 4, we evaluated the effect of shaking container 1 up and down on the amount of oil remaining. We performed the following methods (1) to (4).

(1) To prepare container 1, a PET container with an internal volume of 600 g is filled with approximately 15 g of edible oil, and the weight of the oil poured in is accurately weighed.
(2) Tilt 160° in 1 second, and the point when it is fully tilted is considered to be 0 seconds.
(3) After 15 seconds, the container is shaken up and down for 5 seconds and the amount of oil dispensed at that point is weighed.
(4) The difference between the amount of oil put into container 1 in (1) and the amount of oil discharged is defined as the amount of oil remaining in the container.

The following results were obtained from the table shown in Figure 4. In other words, it became clear that shaking the container 1 up and down was not effective in reducing the amount of residual oil.

The conclusion from the above experiments is that when using up all the oil in a container, tilting the container so that the inclination angle θ is 150° to 165°, not 180°, and especially 160°, and leaving it still can sufficiently reduce the amount of oil remaining in the container. In the present invention, shaking the container up and down is not excluded, but leaving it still is preferable.

Therefore, the predetermined inclination angle θ of the container body 10 is set within the range of 150° to 165° as the angle of the container mouth 20 from the vertically upward to the downward direction when the contents are being discharged. In other words, the container 1 is configured to have a guide means so that the inclination angle θ of the container body 10 is 150° to 165°, preferably 160°.

Figure 5(a) is a front view of a container 1 having a line 32 as a guide means formed on the container body 10 according to the first embodiment, and Figure 5(b) is a front view showing a state in which the container mouth 20 of the container 1 shown in Figure 5(a) is tilted downward at an inclination angle θ. The inclination angle θ is set to 150° to 165°, and preferably, the inclination angle θ is set to 160°. As shown in Figure 5(a), a line 32 is formed on the main body outer wall 10a of the container main body 10 along the guide line 54, which is a line segment having an angle of (180°-θ) from the z-axis 52. Note that the container main body 10 and the main body outer wall 10a are, for example, cylindrical, elliptical cylindrical, polygonal prism, conical, elliptical conical, polygonal pyramid, truncated cone, or polygonal pyramid, so that the line 32 only needs to be linear or appear linear when viewed in a plan view, as shown in Figures 5(a) and (b).

As shown in FIG. 5(b), when a person expels the contents contained inside the container body 10 from the container mouth 20, the person holds the container body 10 with, for example, the fingers and points the container mouth 20 downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the line 32 on the container body 10 is in the up-down direction (vertical direction). This adjusts the inclination of the container body 10 to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in expelling the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in particular in expelling the last few drops of the contents.

Figure 5(c) is a front view of a container having a barcode 33 as a guiding means formed on the container body 10 according to the first embodiment, and Figure 5(d) is a front view showing the state in which the container mouth 20 of the container 1 shown in Figure 5(c) is tilted downward A at an inclination angle θ. The inclination angle θ is set to 150° to 165°, and preferably, the inclination angle θ is set to 160°. As shown in Figure 5(c), the barcode 33 is formed on the main body outer wall 10a of the container main body 10 so as to be perpendicular to the guiding line 54, which is a line segment having an angle of (180°-θ) from the z-axis 52. Note that the container main body 10 and the main body outer wall 10a are, for example, cylindrical, elliptical cylindrical, polygonal prism, conical, elliptical conical, polygonal pyramid, truncated cone, or polygonal pyramid, and therefore, when viewed in a plane, it is sufficient that the barcode 33 appears horizontal.

As shown in FIG. 5(d), when a person ejects the contents contained inside the container body 10 from the container mouth 20, the container body 10 is held, for example, with the fingers and the container mouth 20 is directed downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the barcode 33 attached to the container body 10 is horizontal (left-right direction). As a result, the inclination of the container body 10 is adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in ejecting the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in ejecting the last few drops of the contents. In another embodiment, the inclination of the container body 10 may be adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°) by tilting the container body 10 so that the barcode 33 attached to the container body 10 is in the vertical direction (up and down direction).

Figure 5(e) is a front view of a container having a character string 34 as a guide means formed on the container body 10 according to the first embodiment, and Figure 5(f) is a front view showing the container mouth 20 of the container 1 shown in Figure 5(e) tilted downward at an inclination angle θ. The line (underline) tangent to the character string 34 does not need to be written, and a person can recognize the character string 34 and the direction of the character string 34 (for example, the line tangent to the character string 34) at the same time. There is no limit to the number of characters in the character string, and for example, even one character can form a character string. The inclination angle θ is set to 150° to 165°, preferably 160°. As shown in Figure 5(e), the character direction and/or character string of the character string 34 is formed on the main body outer wall 10a of the container body 10 so as to be perpendicular to the guide line 54, which is a line segment having an angle of (180°-θ) from the z-axis 52. In addition, since the container body 10 and the body outer wall 10a are, for example, cylindrical, elliptical cylindrical, polygonal prism, conical, elliptical conical, polygonal pyramidal, truncated conical, or polygonal pyramidal, it is sufficient that the characters or letter strings 34 appear horizontal when viewed in a plan view.

As shown in FIG. 5(f), when a person ejects the contents contained inside the container body 10 from the container mouth 20, the person holds the container body 10 with, for example, the fingers and points the container mouth 20 downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the direction of the characters and/or the characters of the character string 34 attached to the container body 10 are horizontal (left-right direction). As a result, the inclination of the container body 10 is adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in ejecting the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in ejecting the last few drops of the contents. In another embodiment, the inclination of the container body 10 may be adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°) by tilting the container body 10 so that the orientation of the characters of the character string 34 attached to the container body 10 and/or the character string are in the vertical direction (up and down direction).

Figure 5(g) is a front view of a container 1 having a figure 35 as a guiding means formed on the container body 10 according to the first embodiment, and Figure 5(h) is a front view showing the state in which the container mouth 20 of the container 1 shown in Figure 5(g) is tilted downward A at an inclination angle θ. The line tangent to the figure 35 does not need to be written, and a person can recognize the direction of the figure 35 (for example, the line tangent to the figure 35) at the same time as recognizing the figure 35. The inclination angle θ is set to 150° to 165°, preferably 160°. As shown in Figure 5(g), the picture or direction of the figure 35 and/or the figure row are formed on the main body outer wall 10a of the container body 10 so as to be perpendicular to the guiding line 54, which is a line segment having an angle of (180°-θ) from the z-axis 52. In addition, since the container body 10 and the body outer wall 10a are, for example, cylindrical, elliptical cylindrical, polygonal prism, conical, elliptical conical, polygonal pyramidal, truncated conical, or polygonal pyramidal, it is sufficient that the figure and the row of figures 35 appear horizontal when viewed in a plan view.

5(h), when a person ejects the contents contained inside the container body 10 from the container mouth 20, the container body 10 is held, for example, with the fingers and the container mouth 20 is turned downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the picture or the direction of the figure 35 attached to the container body 10 and/or the figure row are horizontal (left-right direction). As a result, the inclination of the container body 10 is adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in ejecting the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in ejecting the last few drops of the contents. In another embodiment, the inclination of the container body 10 may be adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°) by tilting the container body 10 so that the orientation of the picture or figure and/or the row of figures of the figure 35 attached to the container body 10 is vertical (up and down).

Fig. 6(a) is a front view of a container according to the first embodiment with a label 36 attached as a guide means to the container body, and Fig. 6(b) is a front view showing the container mouth 20 of the container 1 shown in Fig. 6(a) tilted downward at an angle θ. As shown in Fig. 6(a), a label 36, such as a plastic sheet or paper sheet with a figure 36a attached thereto, is attached to the container body 10. As shown in Fig. 6(a), the label 36 is formed as a label 36 that is perpendicular to the guide line 54, which is a line segment that is angled at (180°-θ) from the z-axis 52. As shown in Fig. 6(a), the figure 36a is formed as a figure 36a that is aligned with the guide line 54, which is a line segment that is angled at (180°-θ) from the z-axis 52.

As shown in FIG. 6(b), when a person expels the contents contained inside the container body 10 from the container mouth 20, the person holds the container body 10 with, for example, the fingers and points the container mouth 20 downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the label 36 and/or the figure 36a attached to the container body 10 are vertical (vertical). This adjusts the inclination of the container body 10 to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in expelling the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in expelling the last few drops of the contents.

Figure 7(a) is a front view of a container according to the first embodiment, with a label 37 affixed to the container body 10 and lines 37a and the like displayed on the back of the label 37 as guiding means, Figure 7(b) is a cross-sectional view taken along line B-B of Figure 7(a), and Figure 7(c) is a front view of the container 1 shown in Figure 7(a) when viewed from direction C of Figure 7(b) with the container mouth 20 tilted downward in direction A at an inclination angle θ.

Containers 1 that contain edible oil 70 and the like are often transparent or semi-transparent. In the example shown in FIG. 7(a), lines 37a and the like are displayed as guiding means on the back of label 37. Label 37 is not, for example, attached to the entire circumference of container body 10, or is a transparent label portion, and therefore, as shown in FIGS. 7(b) and (c), lines 37a as guiding means on the back of label 37 can be seen through transparent container 1. For example, the product name that is usually displayed is displayed on the front of label 37. This makes it possible to make lines 37a as guiding means visible while maintaining the design of the product.

As shown in FIG. 7(c), when a person ejects the contents contained inside the container body 10 from the container mouth 20, the container body 10 is held with, for example, the fingers and the container mouth 20 is turned downward (direction A). At this time, the person visually recognizes the line 37a as a guide means on the back side of the label 37 through the transparent container 1. The person visually and psychologically tilts the container body 10 so that the line 32 on the container body 10 is in the up-down direction (vertical direction). As a result, the inclination of the container body 10 is adjusted to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in ejecting the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in ejecting the last few drops of the contents.

Figure 8 (a) is a front view of the container 1 in a state where a rib 38 as a guide means is formed on the container body 10 according to the first embodiment, and Figure 8 (b) is a front view showing a state where the container mouth 20 of the container 1 shown in Figure 8 (a) is tilted downward in the direction A at an inclination angle θ. In the same manner as in the above-described embodiment, a rib 38 is formed on the main body outer wall 10a of the container body 10 along the guide line 54, which is a line segment having an angle of (180°-θ) from the z-axis 52. This rib 38 is formed, for example, around the entire circumference of the main body outer wall 10a of the container body 10. When the container 1 is a plastic container, the container body 10 and the rib 38 can be formed integrally when the container 1 is molded. This is expected to improve the rigidity of the container body 10 and also make it easier to grip the container body 10.

As shown in FIG. 8(b), when a person expels the contents contained inside the container body 10 from the container mouth 20, the person holds the container body 10 with, for example, the fingers and points the container mouth 20 downward (direction A). At this time, the person visually and psychologically tilts the container body 10 so that the rib 38 on the container body 10 is in the up-down direction (vertical direction). This adjusts the inclination of the container body 10 to the above-mentioned inclination angle θ (150° to 165°, preferably 160°). At this time, the container 1 is in a state suitable for use in expelling the contents, for example, edible oil 70, from the container mouth 20, and is in a state suitable for use in particular in expelling the last few drops of the contents.

Second embodiment of the present invention
A container 100 according to a second embodiment of the present invention is a storage container having a container body 110 for storing contents therein, and a container mouth 120 provided on the upper part of the container body 110 for discharging the contents, and the container body 110 is configured to have an guiding means for guiding the container body 110 to a predetermined inclination angle when discharging the contents. In the second embodiment, the guiding means is one that relies on gravity, and for example, the guiding means is a handle portion 150 such as a handle hole 155, a handle knob 156, or a recess provided on the container body, and is configured so that the container body 110 has a predetermined inclination angle θ due to gravity when the handle portion 150 is held to discharge the contents from the container mouth 120.

Figure 9(a) is a front view of a container in which a handle hole 155 is formed as a guide means in the container body 110 according to the second embodiment, and Figure 9(b) is a front view showing a state in which the container mouth 120 of the container 100 shown in Figure 9(a) is tilted at an inclination angle θ in the downward direction A by holding the handle hole 155. Also, Figure 10(a) is a front view of a container 1 in which a handle knob 156 is formed as a guide means in the container body 110 according to the second embodiment, and Figure 10(b) is a front view showing a state in which the container mouth 120 of the container 100 shown in Figure 10(a) is tilted at an inclination angle θ in the downward direction A by holding the handle knob 156.

In other words, the second embodiment utilizes gravity acting on the container 100 when discharging the contents from the container mouth 120 by holding the handle 150, such as a handle hole 155, handle knob 156, or recess, provided in the container body 110 as a guide means. Gravity acts on the center of gravity G of the container 100, and the line segment connecting the handle 150 and the center of gravity G is approximately vertical. As a result, the inclination angle θ of the container body 110 becomes a predetermined inclination angle, enabling a state of use suitable for discharging all the contents from the container mouth 120.

The predetermined inclination angle θ is 150° to 165°, as in the first embodiment, and preferably the inclination angle θ is 160°. The center of gravity G of the container 100 changes depending on the amount of content remaining, but the position of the handle 150 should be set so that the inclination angle θ is 150° to 165° when there is only a small amount remaining.

As shown in Figures 9(b) and 10(b), when a person expels the contents contained inside the container body 10 from the container mouth 20, the person holds the handle 150 (handle hole 155, handle knob 156, recess, etc.) of the container 100 with, for example, the fingers, and points the container mouth 20 downward (in the direction A). At this time, the container 100 is tilted by gravity so that the center of gravity G passes through the Z axis, and the tilt angle θ is adjusted to 150° to 165°, preferably 160°. At this time, the container 100 is in a state suitable for use in expelling the contents, for example, edible oil 70, from the container mouth 120, and is in a state suitable for use in particular in expelling the last few drops of the contents.

[Third embodiment of the present invention]
FIG. 11A is a three-dimensional perspective view of a can container 300 as a container according to the third embodiment, in which a line 330 is formed as a guide means on a can container body 310. As shown in FIG.

As shown in FIG. 11(a), the can container 300 is often covered with a vertical surface 315 with respect to the ground. As in the first and second embodiments, a line 330 serving as a guide means is attached to the container body 10 on the vertical surface 315. When dispensing the contents, the can container 300 is tilted so that the line 330 serving as a guide means is at an angle (horizontal, vertical) that is easy for the user to see. This makes it possible for the inclination angle θ of the can container 300 to be a predetermined inclination angle (150° to 165°, preferably 160°), enabling a suitable usage state for dispensing all the contents from the container mouth 320.

Figure 11(a) shows a pillow container as an inner bag, and the pillow container can be covered with an outer box (such as a cardboard box). In this case, the line 330 as a guide means can be written on the outer box.

Figure 11(b) is a three-dimensional perspective view of a pillow container 400 as a container according to the third embodiment, in which a line 430 is formed as a guide means on the pillow container body 410.

As shown in FIG. 11(b), the pillow container 400 is a pillow-shaped container formed, for example, by sealing two film-like sheets back to back to form a cylinder, sealing the bottom at a specified length, and cutting it. The line 430 as a guide means is formed on the curved wall portion 415, but when the pillow container 400 is viewed in a plane, the line 430 only needs to be straight or appear straight. When the contents are discharged, the pillow container 400 is tilted so that the line 430 as a guide means is at an angle (horizontal, vertical) that is easy for the user to see. As a result, the inclination angle θ of the pillow container 400 becomes a specified inclination angle (150° to 165°, preferably 160°), making it possible to use the pillow container 400 in a state suitable for discharging the contents from the container mouth portion 420.
