Description

[Technical Field]

[0001] The present invention relates to individual containers and interconnected containers. [Background technology]

[0002] Conventionally, disposable individual containers have been known, such as those shown in Patent Document 1 below, which include a container body having a storage space for storing a single-use amount of contents, and a sealing material that seals the opening of the storage space so that it can be opened. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-44682 Summary of the Invention [Problem to be solved by the invention]

[0004] When peeling the seal material from the container body and dispensing the contents, it may be difficult to dispense the contents little by little without getting them on the hands.

[0005] The present invention provides an individual container and a connected container that can dispense contents little by little from a storage space without the contents sticking to hands. [Means for solving the problem]

[0006] An individual container according to one aspect of the present invention includes a pair of triangular wall portions facing each other in one direction perpendicular to a vertical direction, a first rectangular wall portion and a second rectangular wall portion connecting the pair of triangular wall portions to each other in the one direction, and a sealant sealing a lower end opening of a storage space surrounded by the pair of triangular wall portions, the first rectangular wall portion, and the second rectangular wall portion, wherein the first rectangular wall portion and the second rectangular wall portion extend upward as they approach each other in another direction perpendicular to the vertical direction and the one direction, the inclination angle of the first rectangular wall portion with respect to the vertical direction being larger than the inclination angle of the second rectangular wall portion with respect to the vertical direction, and the size of the triangular wall portion in the other direction is The second rectangular wall portion has a first valley fold line extending in the one direction, and the pair of triangular wall portions have two first mountain fold lines that extend from an upper end and a lower end at a connecting portion with the second rectangular wall portion in a direction approaching each other in the up-down direction as they move away from each other in the other direction, and intersect with each other; second valley fold lines that connect the ends of the first valley fold lines in the one direction and the intersections of the first mountain fold lines to each other; and second mountain fold lines that extend downward as they move away from the intersections and the second valley fold lines in the other direction, and reach the opposing corners of the three corners of the triangular wall portion that face each other in the other direction to the first mountain fold line.

[0007] The second rectangular wall portion has a first valley fold line, and the pair of triangular wall portions have a first mountain fold line, a second valley fold line, and a second mountain fold line. Therefore, when the sealing material is peeled off from the individual container and the upper end of the individual container is pressed down with the lower end opening of the storage space partially open, the first valley fold line and the second valley fold line bend toward the inside of the storage space, and the first mountain fold line and the second mountain fold line bend toward the outside of the storage space. Therefore, the internal volume of the storage space is steadily reduced depending on the amount the upper end of the individual container is pressed down, allowing the contents of the storage space to be dispensed little by little. To dispense the contents, after partially opening the lower end opening of the storage space, the upper end of the individual container is simply pressed down, allowing the user to keep their hands away from the dispensed contents and preventing the contents from sticking to their hands.

[0008] The housing may include a flange portion surrounding the entire lower end opening of the storage space, the sealing material being attached to the underside of the flange portion, and a discharge recess being recessed upward and projecting in the other direction from the lower end of the first rectangular wall portion on the underside of the portion of the flange portion that protrudes in the other direction, the portion of the sealing material that closes the lower end opening of the storage space being inseparably fixed to the underside of the flange portion, and the portion of the sealing material that closes the discharge recess being separable from the other portions and removably attached to the underside of the flange portion.

[0009] The portion of the sealing material that blocks the lower end opening of the storage space is fixed inseparably to the underside of the flange portion, and the portion of the sealing material that blocks the discharge recess is separable from the other portions and is removably attached to the underside of the flange portion.Therefore, when discharging the contents, it is possible to easily and accurately open part of the lower end opening of the storage space, and it is possible to reliably discharge the contents in small amounts without them sticking to hands. Of the first and second rectangular wall portions, the angle of inclination relative to the vertical direction is large and the distance between the upper and lower ends in a plan view is long, and the discharge recess is adjacent in the other direction to the lower end of the first rectangular wall portion, which cannot be bent when an individual container is pressed down.Therefore, when the upper end of an individual container is pressed down, the contents of the storage space tend to flow toward the discharge recess, making it easy to discharge the contents in small amounts.

[0010] A connected container according to one embodiment of the present invention is a connected container in which four individual containers according to one embodiment of the present invention are connected in the other direction via a breakable weakened portion extending in the one direction, and the individual containers adjacent to each other in the other direction are bent along the weakened portion, and when the first rectangular wall portion of one individual container and the second rectangular wall portion of the other individual container are abutting or close to each other, the external shape of the connected container is square when viewed from the one direction.

[0011] When adjacent individual containers in the other direction are folded along the weakened portions, and the first rectangular wall portion of one individual container and the second rectangular wall portion of the other individual container are abutting or close to each other, the outer shape of the connected container is square when viewed from the one direction.Therefore, a connected container made up of four individual containers connected in the other direction via breakable weakened portions extending in the one direction can be folded compactly around an axis extending in the one direction. [Effects of the Invention]

[0012] According to one aspect of the present invention, when the contents are discharged from the storage space, the contents can be discharged in small amounts without sticking to the hands. [Brief explanation of the drawings]

[0014] Hereinafter, an embodiment of the individual containers 1a and the connected container 1 will be described with reference to the drawings. As shown in Figures 1 and 2, the individual container 1a has a pair of triangular wall portions 11, a first rectangular wall portion 13, a second rectangular wall portion 14, a sealing material 15, a base portion 16, and a flange portion 17. It should be noted that the individual container 1 a may not have at least the base portion 16 out of the base portion 16 and the flange portion 17 .

[0015] The triangular wall portion 11 is formed like a plate with its front and back surfaces facing one direction X perpendicular to the vertical direction Z. The pair of triangular wall portions 11 face each other in the one direction X. The size of the triangular wall portion 11 in the other direction Y perpendicular to the vertical direction Z and the one direction X decreases upward. When viewed from the one direction X, the triangular wall portion 11 has a right-angled triangular shape. In the triangular wall portion 11, the right-angle portion is located at the upper end 11a, and the hypotenuse portion is located at the lower end 11b and extends in the other direction Y. In the illustrated example, the upper end 11a of the triangular wall portion 11 is linear and extends slightly in the other direction Y when viewed from the one direction X, and the extension lines of the remaining two sides 11d and 11c of the triangular wall portion 11 other than the hypotenuse portion form a right angle. Note that the upper end 11a of the triangular wall portion 11 may be a corner that points upward.

[0016] The first rectangular wall portion 13 and the second rectangular wall portion 14 connect a pair of triangular wall portions 11 to each other in one direction X. The first rectangular wall portion 13 and the second rectangular wall portion 14 extend upward as they approach each other in the other direction Y. In each of the first rectangular wall portion 13 and the second rectangular wall portion 14, two of the four sides are located at upper ends 13a, 14a and lower ends 13b, 14b and extend in the one direction X, and the remaining two sides 13c, 14c coincide with the remaining two sides 11d, 11c of the adjacent triangular wall portion 11.

[0017] Hereinafter, of the remaining two sides 11d, 11c of the triangular wall portion 11, the side that coincides with one side 14c of the remaining two sides 14c of the second rectangular wall portion 14 will be referred to as the connecting side 11c.

[0018] The angle of inclination of the first rectangular wall portion 13 relative to the vertical direction is larger than the angle of inclination of the second rectangular wall portion 14 relative to the vertical direction. In plan view, the first rectangular wall portion 13 and the second rectangular wall portion 14 each have an isosceles trapezoidal shape with upper ends 13a, 14a and lower ends 13b, 14b forming short sides and the remaining two sides 13c, 14c forming long sides. The length of the long sides of the first rectangular wall portion 13 is longer than the length of the long sides of the second rectangular wall portion 14. The planar area of ​​the first rectangular wall portion 13 is larger than the planar area of ​​the second rectangular wall portion 14.

[0019] The upper end of the individual container 1a is formed by the upper ends 11a, 13a, and 14a of the triangular wall portion 11, the first rectangular wall portion 13, and the second rectangular wall portion 14, respectively, and has a rectangular shape that is long in one direction X when viewed from the vertical direction Z, and is formed like a flat plate with its front and back surfaces facing the vertical direction Z. The upper ends 13a, 14a of the first rectangular wall portion 13 and the second rectangular wall portion 14 are connected to each other in the other direction Y via the upper ends of the individual containers 1a, which are formed in a flat plate shape. The upper ends 13a, 14a of the first rectangular wall portion 13 and the second rectangular wall portion 14 may be directly connected to each other to form a corner that is pointed upward. With the second rectangular wall portion 14 facing up and down, the outer peripheral edge of the portion of the flange portion 17 that protrudes in the other direction Y from the lower end portion 14b of the second rectangular wall portion 14 and the upper end portion 14a of the second rectangular wall portion 14 can be grounded to make the individual container 1a stand on its own. This allows the individual container 1a to stand on its own while the contents of the storage space are being completely discharged from the discharge recess 17a (described later).

[0020] The sealing material 15 seals the lower end opening of the storage space surrounded by the pair of triangular wall portions 11, the first rectangular wall portion 13, and the second rectangular wall portion 14. The storage space contains contents such as liquids, semi-liquids, etc. Examples of contents include soy sauce, sauces, ketchup, mustard, detergent, shampoo, etc.

[0021] The base portion 16 and the flange portion 17 are each formed in an annular shape, and surround the entire periphery of the lower end opening of the accommodation space. Base portion 16 protrudes downward from lower end portions 11b, 13b, and 14b of triangular wall portion 11, first rectangular wall portion 13, and second rectangular wall portion 14, respectively, and flange portion 17 protrudes from the lower end portion of base portion 16 in a direction perpendicular to the up-down direction toward the outside of the storage space. Sealing material 15 is affixed to the underside of flange portion 17.

[0022] In the illustrated example, a discharge recess 17a is formed on the lower surface of a portion of the flange 17 that protrudes in the other direction Y from the lower end 13b of the first rectangular wall 13. The discharge recess 17a is recessed upward and protrudes in the other direction Y from the lower end opening of the accommodation space. The discharge recess 17a communicates with the accommodation space and is integrally formed on the lower surface of the flange 17 and the inner surface of the base 16. The discharge recess 17a is provided in the center, in the one direction X, of the portion of the flange 17 that protrudes in the other direction Y from the lower end 13b of the first rectangular wall 13.

[0023] A portion of the sealing material 15 that closes the lower end opening of the storage space (hereinafter referred to as the fixed portion 15a) is inseparably fixed to the lower surface of the flange portion 17. A portion of the sealing material 15 that closes the discharge recess 17a (hereinafter referred to as the separated portion 15b) is separable from the fixed portion 15a and is peelably attached to the lower surface of the flange portion 17. A breakable weakened line 15c extending in one direction X is formed in the boundary portion of the sealing material 15 between the fixed portion 15a and the separated portion 15b. The weakened line 15c is located outside the storage space in the other direction Y and is located on the lower surface of the flange portion 17. The separated portion 15b and the weakened line 15c are provided over the entire length in the one direction X of the portion of the flange portion 17 that protrudes in the other direction Y from the lower end portion 13b of the first rectangular wall portion 13. It is also possible to adopt a configuration in which the flange portion 17 does not have a discharge recess 17a, and the sealing material 15 has a two-layer structure in part, with a through hole formed in the inner layer portion that communicates with the storage space, and the outer layer portion peelably adhered to the inner layer portion.

[0024] The second rectangular wall portion 14 has a first valley fold line 21 extending in one direction X formed thereon. The first valley fold line 21 is provided in the middle of the second rectangular wall portion 14 in the up-down direction Z, over the entire length of the second rectangular wall portion 14 in one direction X. The first valley fold line 21 is provided in an upper portion of the second rectangular wall portion 14 that is located above the center in the up-down direction Z. The second rectangular wall portion 14 extends inward in the other direction Y, which is inside the storage space, as it moves from both end portions along the up-down direction Z toward the first valley fold line 21. Note that the second rectangular wall portions 14 may be positioned on the same straight line when viewed from the one direction X.

[0025] The pair of triangular wall portions 11 are formed with a first mountain fold line 22, a second valley fold line 23, and a second mountain fold line 24.

[0026] Two first mountain fold lines 22 are provided, and extend toward each other in the up-down direction Z as they move away from the upper and lower ends of the connecting side 11c of the triangular wall portion 11, which is the connecting portion with the second rectangular wall portion 14, in the other direction Y, and then intersect. The two first mountain fold lines 22 extend in the other direction Y from the connecting side 11c of the triangular wall portion 11 and terminate at an intersection 22a. The positions of the intersection 22a and the upper end 11a of the triangular wall portion 11 in the other direction Y are equal to each other. The second valley fold lines 23 connect the ends of the first valley fold lines 21 in one direction X to the intersecting portions 22a of the first mountain fold lines 22. The second valley fold lines 23 extend downward as they move away from the first valley fold lines 21 in the other direction Y.

[0027] In the triangular wall portion 11, the area surrounded by the first mountain fold line 22 and the connecting side 11c extends outward in one direction X, which is the outside of the storage space, as it moves away from the connecting side 11c in the other direction Y. The area surrounded by the first mountain fold line 22 and the connecting side 11c extends inward of the storage space from both end portions along the up-down direction Z as it approaches the second valley fold line 23.

[0028] The second mountain fold line 24 extends downward as it moves away from the intersection 22a and the second valley fold line 23 in the other direction Y, and reaches an opposing corner 11e, one of the three corners of the triangular wall portion 11, that faces the first mountain fold line 22 in the other direction Y. As shown in FIG. 6, the second mountain fold line 24 and the second valley fold line 23 are located on the same straight line when viewed from the one direction X. When viewed from the one direction X, the angle formed by the opposing corner 11e is approximately 30°. A protruding rib 24a is formed on the second mountain fold line 24, extending over the entire length excluding both end portions in the other direction Y. Of both end portions of the protruding rib 24a, the end portion on the intersection 22a side is away from the intersection 22a in the other direction Y and is located at a position in the other direction Y equivalent to the upper end portion 13a of the first rectangular wall portion 13.

[0029] In the triangular wall portion 11, the area located on the opposing corner 11e side along the other direction Y from the first mountain fold line 22 extends toward the outside in one direction X, which is outside the storage space, as it approaches the second mountain fold line 24 along the vertical direction Z.

[0030] As shown in Figure 5, the connected container 1 is configured by four individual containers 1a connected in one direction X via first breakable weakened portions (weakened portions) 18 extending in the other direction Y. In the connected container 1, a plurality of individual containers 1a are also connected in one direction X via second breakable weakened portions 19 extending in the other direction Y. The first weakened portions 18 and second weakened portions 19 connect the flange portions 17 and the seal members 15 of the individual containers 1a to each other. The connected container 1 does not necessarily have to have a plurality of individual containers 1a connected in one direction X via the second weakened portions 19.

[0031] 6, when adjacent individual containers 1a in the other direction Y are bent along the first weakened portions 18, and the first rectangular wall portion 13 of one individual container 1a and the second rectangular wall portion 14 of the other individual container 1a are in contact with or close to each other, the outer shape of the connected container 1 is square when viewed from the one direction X. In this case, the flange portions 17 adjacent to each other across the first weakened portions 18 and the base portions 16 connected to these flange portions 17 are square when viewed from the one direction X and define a space A extending in the one direction X.

[0032] As described above, in the individual container 1a according to this embodiment, the second rectangular wall portion 14 has the first valley fold line 21, and the pair of triangular wall portions 11 have the first mountain fold line 22, the second valley fold line 23, and the second mountain fold line 24. Therefore, when the sealing material 15 is peeled off from the individual container 1a and the upper end of the individual container 1a is pressed down with the lower end opening of the storage space partially open, as shown in Fig. 3, the first valley fold line 21 and the second valley fold line 23 bend toward the inside of the storage space, and the first mountain fold line 22 and the second mountain fold line 24 bend toward the outside of the storage space, as shown in Fig. 4. Therefore, the internal volume of the storage space is stably reduced depending on the amount the upper end of the individual container 1a is pressed down, allowing the contents of the storage space to be dispensed little by little.

[0033] When discharging the contents, after opening a portion of the lower end opening of the storage space, the upper end of the individual container 1a can be pressed down, which allows the hands to be kept away from the contents being dispensed and prevents the contents from sticking to the hands.

[0034] Of the sealing material 15, the fixed portion 15a that closes the lower end opening of the storage space is fixed inseparably to the underside of the flange portion 17, and of the sealing material 15, the detachable portion 15b that closes the discharge recess 17a is detachable from the fixed portion 15a and is removably attached to the underside of the flange portion 17. Therefore, when discharging the contents, part of the lower end opening of the storage space can be opened easily and accurately, and the contents can be reliably discharged in small amounts without sticking to the hands.

[0035] Of the first rectangular wall portion 13 and the second rectangular wall portion 14, the angle of inclination with respect to the vertical direction Z is large and the distance between the upper end portion 13a and the lower end portion 13b in a plan view is long, and the discharge recess 17a is adjacent to the lower end portion 13b of the first rectangular wall portion 13, which cannot be bent when the individual container 1a is pressed down, so when the upper end portion of the individual container 1a is pressed down, the contents in the storage space tend to flow toward the discharge recess 17a, making it easy to discharge the contents in small amounts.

[0036] As shown in Figure 6, adjacent individual containers 1a in the other direction Y are folded along the first weakened portions 18, and the first rectangular wall portion 13 of one individual container 1a and the second rectangular wall portion 14 of the other individual container 1a are in contact with or close to each other, so that the outer shape of the connected container 1 is square when viewed from the one direction X. Therefore, the connected container 1, which is made up of four individual containers 1a connected in the other direction Y via the breakable first weakened portions 18 extending in the one direction X, can be folded around the axis O extending in the one direction X to make it compact.

[0037] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0038] For example, the first valley fold line 21 may be provided in the center of the second rectangular wall portion 14 in the up-down direction Z.

[0039] In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described embodiments and the above-described variations may be combined as appropriate.
