Abstract
Description
[Technical Field]
[0001] The present invention relates to a dispensing container. [Background technology]
[0002] A known discharge container is one in which a cylindrical cap with a top is fitted onto the mouth and neck of a tubular container body, and a discharge tube is erected from the top wall of the cap (Patent Document 1). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Patent Publication No. 2023-161985 Summary of the Invention [Problem to be solved by the invention]
[0004] When discharging a paste-like substance, if the discharge port of the cap of the container of Patent Document 1 is enlarged, the paste-like substance will be discharged more than necessary. to In recent years, there has been a demand for a method to easily and visually check the amount of paste-like seasonings that can be dispensed. 、 If the contents come out all at once, it will not be possible to meet the demand for simple, fixed-volume dispensing.
[0005] The first object of the present invention is to provide a dispensing container that can avoid the inconvenience of excessive discharge of contents, and the second object is to meet the demand for easy constant-volume dispensing from said container. [Means for solving the problem]
[0006] The first means comprises a container body 2 that stands up a mouth and neck portion 6, a cap body (10) fitted onto the mouth / neck portion (6) and having a top wall (24) covering the opening of the mouth / neck portion (6), a discharge tubular portion (32) erected on a part of the top wall is provided with a ceiling wall portion (36) closing the upper surface thereof, and a horizontal discharge port (34) opening in the discharge tubular portion (32); Equipped with The top wall 24 is disposed around the periphery of the discharge tube portion 32 and has a circumferential fluid guide surface portion G that is inclined upward and outward from the inside when viewed in the radial direction.
[0007] 1(A) and 2(A), a discharge tube portion 32 having an upper surface closed by a ceiling wall portion 36 is erected from the top wall 24 of a cap body 10 fitted onto the mouth and neck portion 6 of a container body 2. A horizontal discharge port 34 is opened in the discharge tube portion 32. A fluid guide surface G is provided around the periphery of the discharge tube portion 32, inclining upward and outward from the inside. 1(B) and 2(B), during the dispensing operation, this structure causes the trajectory of the fluid flow (streamline S) to change direction from vertical to horizontal as it passes through the discharge port 34, and then changes from horizontal to upward and outward along the fluid guide surface G. In this way, the discharge direction of the contents (e.g., a paste-like substance) can be regulated, so the amount of discharge can be reduced relative to the opening area of the discharge port 34, and the problem of excessive discharge of the contents can be alleviated.
[0008] The second means includes the first means, and the height of the outer peripheral end P of the fluid guide surface portion G is set lower than the height of the upper surface of the ceiling wall portion .
[0009] In this means, as shown in FIG. 1(B), the height of the outer peripheral end P of the fluid guide surface portion G is made lower than the height of the upper surface of the ceiling wall portion . This structure prevents the direction of the fluid flowing out along the fluid guide surface G from being excessively upward, and allows the discharge direction to be changed within an appropriate range.
[0010] The third means includes the first means, and the cap body 10 has an outward flange-like wall portion 14 extending from the top of the mounting tubular portion 12 fitted into the mouth and neck portion 6, and has an outer tubular wall 16 for quantitative measurement suspended from this outward flange-like wall portion 14.
[0011] In this means, as shown in Figs. 1(A) and 2(A), the cap body 10 is provided with an outer cylindrical wall 16 for quantitative measurement. This structure allows for easy visual discharge of a fixed amount of material. That is, with the container turned upside down, an imaginary column I is formed from the outer cylinder wall 16, as shown by the imaginary lines in Figures 1(C) and 2(C), and discharge is terminated when the diameter of this imaginary column I matches the outer diameter of the contents, such as a paste-like material, that has spread over the discharged surface T. This measurement method uses the diameter of the outer cylinder wall 16 as an objective reference standard, and is therefore more reliable than simple eyeballing without such a reference standard.
[0012] The fourth means includes any one of the first to third means, and is attached to the surface 37 of the top wall portion 36, and includes a cover body 50 that extends laterally from the surface 37 to cover the upper part of the fluid guide surface portion G, and a peripheral opening Q is formed between a peripheral edge portion 52 of the cover body 50 and an outer peripheral end portion P of the fluid guide surface portion G, A peripheral opening Q is formed between the peripheral edge 52 of the cover body 50 and the outer peripheral end P of the fluid guide surface G.
[0013] In this means, as shown in FIG. 2(A), a cover body 50 that covers the fluid guide surface G is attached to the surface 37 of the top wall portion . Between the peripheral edge 52 of the cover body 50 and the outer peripheral end P of the fluid guide surface G, a peripheral opening Q is formed. According to this structure, the contents such as a paste-like substance are discharged in a circumferential direction from the circumferential opening Q, so that the discharge direction of the contents can be further regulated.
[0014] The fifth means includes the fourth means, and the cover body 50 is formed of a soft material that can be deformed by the flow pressure of the fluid discharged from the discharge port 34 through the circumferential opening Q.
[0015] In this means, by forming the cover body 50 from a soft material, the cover body 50 can be deformed by the flow pressure of the fluid discharged from the discharge port 34 through the circumferential opening Q, as shown in Figure 2(C). This structure allows the ejection direction of the contents, such as a paste-like substance, to be appropriately regulated, and does not cause the inconvenience of the contents not being easily ejected due to the narrow opening area of the circumferential opening Q. [Effects of the Invention]
[0016] According to the present invention, even if the opening area of the discharge port is set large, the inconvenience of excessive discharge of the contents can be avoided, and the demand for simple constant volume discharge can be met. [Brief explanation of the drawings]
[0017] [Figure 1] 1 shows the structure and operation of a discharge container according to a first embodiment of the present invention, in which (A) is a cross-sectional view seen from the side with the lid closed, (B) is an enlarged view of the main parts, and (C) is an explanatory diagram of the discharge operation in an upside-down state. [Figure 2] 1 shows the structure and operation of a discharge container according to a second embodiment of the present invention, in which (A) is a cross-sectional view seen from the side with the lid closed, (B) is an enlarged view of the main parts, and (C) is an explanatory diagram of the discharge operation in an upside-down state. BEST MODE FOR CARRYING OUT THE INVENTION
[0018] 1 shows a discharge container according to a first embodiment of the present invention. This discharge container is made up of a container body 2, a cap body 10, and an upper lid 40. Each of these members can be made of, for example, a synthetic resin material. An example of an application of this discharge container is a paste-like food such as a seasoning, but it is not limited to food and can be applied to various high-viscosity fluids (referred to as "paste-like substances" in this specification).
[0019] In this embodiment, the container body 2 is a tube-type container body having a mouth and neck part 6 extending from a compressible body part 4 via a shoulder part 5. However, this structure can be modified as appropriate, and the container does not have to be a tube-type container as long as it is a container shape that can be compressed.
[0020] In the illustrated example, the shoulder portion 5 is tapered with a small diameter at the top end. An annular thick portion 9 is formed between the shoulder portion 5 and the mouth / neck portion 6. A notch is recessed in part of the circumferential direction of the thick portion 9 as a locking portion f that engages with a locking piece e (described later). The locking piece e and the locking portion f serve to prevent the cap body 10 from rotating. Furthermore, a radial rib d is provided on the upper surface of the shoulder portion 5.
[0021] In the illustrated example, an inner rib 7 is provided at the upper end of the mouth / neck portion 6. A male thread 8 is formed on the outer surface of the mouth / neck portion 6.
[0022] The cap body 10 is a cylindrical member with a top fitted onto the mouth / neck portion 6, and as shown in Figure 1(A), a horizontal discharge port 34 is opened in a discharge tube portion 32 erected on the top wall 24. In addition, a fluid guide surface portion G is provided around the discharge tube portion 32 to guide the fluid upward and outward. In this specification, the terms "upper" and "lower" refer to the orientation of the container in the upright state shown in Figures 1(A) and 2(A), unless otherwise specified. The discharge port 34 and the fluid guide surface portion G can regulate the discharge direction of the paste-like material. When viewed from above, the outer cylindrical wall 16 for quantitative measurement is provided around the top wall 24. In this specification, "quantitative measurement" means a means for measuring only a fixed amount corresponding to the diameter of the outer tube wall 16, and is meant to be distinguished from measuring means that can measure any amount, such as a known graduated measuring cup. In this embodiment, the cap body 10 has an attachment tubular portion 12 fitted into the mouth / neck portion 6, and an outer tubular wall 16 hanging down via an outward flange-shaped wall portion 14 is connected to the outside of this attachment tubular portion 12, and a top wall 24 is connected to the inside of the attachment tubular portion 12. However, these structures can be modified as appropriate.
[0023] The mounting tube portion 12 has a female thread portion 13 that meshes with the male thread portion 8 . In addition, a vertically long locking piece e is attached to the outer surface of the mounting tube portion 12, extending down to near the shoulder portion 5, and the lower end of this locking piece e is designed to lock onto the locked portion f when the lid is closed. The fitting tube 12 and the mouth / neck portion 6 of the container body 2 may be fitted with an undercut, and the structure can be modified as appropriate.
[0024] The outer cylindrical wall 16 is the outermost peripheral wall (outer circumferential wall) of the cap body 10. In the illustrated example, it is suspended from the peripheral end of the outward flange-shaped wall portion 14. The outward flange-like wall portion 14 is connected to the upper end of the mounting tubular portion 12 . In this embodiment, the outer cylindrical wall 16 is connected to the upper cover 40 via a hinge 22 provided at a portion of the circumference of the outer cylindrical wall 16. The hinge 22 in the illustrated example is composed of a pair of first hinges 22a and a single dogleg-shaped second hinge 22b disposed between the first hinges 22a. A storage recess 21 is formed in the upper part of the outer cylindrical wall 16 to store the lower part of the second hinge 22b. The outer cylindrical wall 16 in the illustrated example is made up of a tapered cylindrical portion 18 which is the upper half and a straight cylindrical portion 20 which is the lower half. When it is desired to easily dispense a fixed amount of paste-like material, the diameter of the straight cylindrical portion 20 is used as a guide, and the body portion 4 of the container body 2 is simply squeezed until the outer diameter of the paste-like material spread on the discharged surface T becomes the same as the diameter of the straight cylindrical portion 20. In this specification, the term "discharged surface" refers to a target surface onto which the discharged paste-like material is to spread. Specifically, when the container is turned upside down as shown in Figure 1(C), imagine a virtual pillar I (a pillar formed by a virtual perpendicular line from the straight cylindrical portion 20) extending vertically from the straight cylindrical portion 20, and end the discharge when the diameter of this virtual pillar I matches the diameter of the paste-like material spread on the discharged surface T. In this measurement method, the straight cylindrical portion 20 facing the discharged surface T serves as a substitute for a ruler, and therefore, more reliable measurements can be made than in the method of simply measuring the outer diameter of the discharged paste-like material by eye without using such an objective comparison object.
[0025] The top wall 24 is a portion that covers the opening of the mouth / neck portion 6 . In this embodiment, as shown in FIG. 1(A), the top wall 24 is formed of a peripheral wall portion 26, a surrounding cylindrical portion 28, an intermediate wall portion 30, a discharge cylindrical portion 32, and a ceiling wall portion 36 which is a central wall portion. However, these structures can be modified as appropriate.
[0026] The peripheral wall portion 26 is provided so as to protrude inward like a flange from the upper end of the mounting tube portion 12. On the lower surface of this peripheral wall portion 26, downward pressure-contact ridges a for pressure-contacting with the upper end surface of the mouth / neck portion 6 are provided around the periphery.
[0027] The surrounding cylindrical portion 28 stands upright from the inner peripheral end of the peripheral wall portion 26 . The surrounding cylindrical portion 28 is a portion that surrounds the discharge cylindrical portion 32 when viewed from above. Although not shown, in this embodiment, the surrounding tubular portion 28 and the discharge tubular portion 32 are both cylindrical and arranged concentrically. However, the shapes and arrangements of these two cylindrical portions can be changed as appropriate. The outer surface of the surrounding cylindrical portion 28 is provided with horizontal pressure-contact ridges b for pressure-contacting with the outer cylindrical seal portion 48 described below. In addition, a ring-shaped wall portion 29 for tightly fitting into the inner rib portion 7 is provided vertically from the surrounding cylindrical wall portion 28.
[0028] The intermediate wall portion 30 is a wall portion that is arranged between the surrounding cylindrical portion 28 and the discharge cylindrical portion 32 and has a circumferential (for example, annular) shape when viewed from above. The upper surface of the intermediate wall portion 30 is formed as a fluid guide surface portion G that guides fluid discharged upward and outward from a discharge port 34 described below. The fluid guide surface portion G in the illustrated example is formed as a curved surface (curved surface) that is horizontal on the inside in the radial direction and gradually increases in gradient toward the outside. This allows the paste-like material discharged sideways (horizontally) from the discharge port 34 described below to flow smoothly upward and outward along the fluid guide surface G without any strain. However, the shape of the fluid guide surface portion G may be an inclined surface, and can be changed as appropriate. It is desirable that the outer peripheral end P of the fluid guide surface portion G is located below an imaginary contour line H extending horizontally from a surface 37 of the top wall portion 36 described below. If this requirement is not met, the contents will be discharged excessively upward (or downward in the inverted state shown in FIG. 1(C)), which is inconvenient.
[0029] The discharge tube portion 32 stands upright from the inner peripheral end of the intermediate wall portion 30 . The illustrated discharge tubular portion 32 is a short cylinder whose height is smaller than its diameter. The illustrated discharge tube portion 32 is a straight tube, and a horizontal discharge port 34 is opened through the wall of the tube. In the illustrated example, multiple ( 3 1) discharge ports 34 are opened. These outlets 34 may be equiangularly arranged in the circumferential direction. This allows the paste-like material to flow out as evenly as possible in all directions from the discharge tube portion 32 during the discharge operation. The discharge port 34 may be a long hole that is elongated horizontally in the circumferential direction of the discharge tube portion 32 . This allows the opening area of the discharge port 34 to be increased.
[0030] The top wall portion 36 is connected to the cylindrical wall of the discharge cylindrical portion 32 so as to close the upper surface of the discharge cylindrical portion 32. As shown in FIG. 1B, the top wall portion 36 has the role of changing the direction of the fluid that has entered the discharge tubular portion 32 in a vertical direction to a horizontal direction so that the fluid flows out of the discharge port 34 . The top wall portion 36 in the illustrated example is formed in the shape of a horizontal flat plate.
[0031] In this embodiment, the upper lid 40 has a lid peripheral wall 42 extending downward from the peripheral edge of a lid plate 44 that covers the upper surface of the cap body 10. The lid peripheral wall 42 is connected to the outer cylinder wall 16 via the hinge 22. An annular seal portion C that is in close contact with the top wall 24 is provided on the underside of the cover plate 44 along the outer peripheral edge P of the fluid guide surface portion G. According to this configuration, by closing the upper lid 40 after the discharging operation, it is possible to prevent the paste-like material remaining near the discharge port 34 after discharging from flowing out to the outside of the fluid guide surface portion G and causing contamination. The annular seal portion C in the illustrated example is formed of an inner cylindrical seal portion 46 that fits tightly against the fluid guide surface G along the outer peripheral end portion P, and an outer cylindrical seal portion 48 that fits tightly against the surrounding cylindrical portion 28. However, these structures can be modified as appropriate. The cover plate 44 also has a finger hook 49 attached to it, positioned on the opposite side to the hinge 22 .
[0032] In the above-described configuration, when discharging, the top lid 40 is opened from the state shown in Fig. 1(A), the container is turned upside down as shown in Fig. 1(C), the top wall 36 is brought close to the discharged surface T, and the body 4 is squeezed. Then, the paste-like material in the container body 2 is forced vertically into the discharge tube part 32, and when it hits the top wall part 36, it changes its course from vertical to horizontal and passes through the discharge port 34. The paste-like material that has passed through the discharge port 34 changes its course along the fluid guide surface G from a horizontal direction to an oblique direction closer to the discharged surface T. This two-stage change in path creates a force-reducing effect, which prevents a large amount of content from being ejected all at once, which can lead to problems such as excessive application of paste-like seasoning onto food. Easily dispenses paste-like materials in fixed quantities deathWhen this is desired, as described above, the container is turned upside down, and the body portion 4 is squeezed while imagining an imaginary pillar I hanging down from the straight cylindrical portion 20, and the squeezing is terminated when the outer diameter of the paste-like material spreading on the discharged surface T becomes the same as the diameter of the straight cylindrical portion 20. In the configuration of the present invention, the ejection direction is regulated to prevent a large amount of contents from being ejected all at once (for example, in a single squeezing operation), so even when the ejected paste-like material spreads along the ejected surface T, there is little chance that it will spread all at once. Therefore, as shown by the solid line in Figure 1(C), at the stage when the extension of the paste-like material has not yet reached the imaginary pillar I, the user can visually check the extent to which the paste-like material has spread, and continue the squeezing operation while adjusting the degree of squeezing of the body part 4, and stop squeezing when the extension reaches the imaginary pillar I. This allows the paste-like material to be discharged in just the right amount, and allows for simple and accurate fixed-quantity discharge.
[0033] According to the above-mentioned configuration and action, the horizontal discharge port 34 is opened in the discharge tube portion 32 whose upper surface is closed by the top wall portion 36, and a fluid guide surface portion G is provided around the discharge tube portion 32. Therefore, by regulating the discharge direction, the inconvenience of excessive discharge of the paste-like material to the outside can be improved. Furthermore, since the cap body 10 is provided with the outer cylindrical wall 16 for measuring the quantity, it is possible to easily discharge the quantity of the discharged material by visual estimation.
[0034] Other embodiments of the present invention will be described below, in which explanations of the same configurations as in the first embodiment will be omitted.
[0035] FIG. 2 shows a discharge container according to a second embodiment of the present invention. In this embodiment, the inner sealing tube portion 46 is omitted from the configuration of the first embodiment, and a thin plate-shaped cover body 50 that covers the fluid guide surface portion G is fixed to the surface 37 of the ceiling wall portion 36 by adhesive or the like, and a circumferential opening Q is formed between the peripheral portion 52 of this cover body 50 and the fluid guide surface portion G. With this configuration, the paste material is discharged circumferentially from the circumferential opening Q, so that the discharge direction of the paste material can be further restricted than in the first embodiment.
[0036] In this embodiment, before the discharge operation, an opening allowance n is provided between the peripheral edge portion 52 of the cover body 50 and the outer peripheral end portion P of the fluid guide surface portion G, and a circumferential opening Q is formed between the two. However, this structure can be modified as appropriate. The term "circumferential" means any shape that allows the paste-like material to pass through from the entire periphery of the cover body 50, and is not limited to "annular". In this embodiment, the paste-like material is ejected in a circular shape through the circular opening Q, and therefore the shape of the paste-like material ejected onto the ejected surface T may also be a ring shape with a blank center (see Figure 2(C)). Even in this case, the dispensing operation is continued until the outer diameter of the paste-like material becomes equal to the diameter of the straight cylindrical portion 20, and the dispensing operation is terminated when this occurs, thereby enabling simple fixed-amount dispensing to be performed in the same manner as in the first embodiment.
[0037] The cover body 50 of this embodiment is a horizontal, disk-like thin plate (including a sheet-like shape), but the shape can be changed as appropriate. The cover body 50 of this embodiment is made of a soft material, and the cover body 50 can be deformed by the flow pressure of the fluid discharged from the discharge port 34 through the circumferential opening Q. This configuration appropriately regulates the ejection direction of the paste-like material and avoids the inconvenience of the paste-like material being difficult to eject smoothly due to the opening area of the circumferential opening Q being too narrow. In this embodiment, the cover body 50 made of a soft material is formed so that when the body 4 is squeezed, it opens (displaces in a direction away from the fluid guide surface G), increasing the opening area of the circumferential opening Q, and when the compression is released, it displaces in a direction to close, decreasing the opening area, thereby improving liquid drainage. As examples of the material and form of the cover, soft materials such as elastomers and films are preferred, but hard materials can also be used. [Explanation of symbols]
