Summary of the Invention

Problems to be Solved by the Invention

[0004] Currently, the applicants are developing a curry in a tube in which curry is contained in a tube-shaped container and children can discharge the curry from the tube and write letters or draw pictures on a plate or on top of rice. Therefore, it was considered to attach a nozzle to the mouth of the tube-shaped container. Patent Document 2 discloses a nozzle with a mouth diameter of about 1.5 to 2 mm at the tip, which can draw clean pictures and letters on foods, cooked foods, etc. with ketchup, etc. However, as a result of the inventors' examination, it was found that, for example, in the case of a nozzle (nozzle) with a small diameter attached to the mouth of a tube container as disclosed in Patent Document 2, the discharged paste meanders even when trying to draw a picture.

[0005] This invention has been made in view of the above problems, and its purpose is to provide a nozzle member that can be attached to a container body so that the discharged contents do not meander. [Means for solving the problem]

[0006] The nozzle member of the present invention has a through-channel formed inside that extends along the axis from one end to the other, and the opening at one end of the through-channel can be attached to the mouth of a container body containing contents, and the nozzle member is for discharging contents supplied from the mouth of the container body through the through-channel from a discharge port formed at the other end when attached to the container body, wherein the through-channel includes a reduced diameter section that narrows in a frustoconical shape toward the other end, and an expanded diameter section formed on the other end side of the reduced diameter section that widens in an inverted frustoconical shape toward the discharge port, and the inner surface of the expanded diameter section is inclined at an angle of 4° to 45° with respect to the axis of the through-channel. According to the present invention with the above configuration, it is possible to prevent the contents discharged from the nozzle member from meandering.

[0007] In the present invention, preferably, an enlarged diameter portion is formed directly and continuously with the reduced diameter portion.

[0008] In the present invention, preferably, the length along the axis of the enlarged diameter portion is 2 mm to 8 mm.

[0009] In the present invention, preferably, the width of the connection portion between the reduced diameter portion and the enlarged diameter portion is 1.5 mm to 5 mm.

[0010] The container of the present invention includes the above-mentioned nozzle member and a container body that contains contents and to which the nozzle member can be attached at the opening.

[0011] In the present invention, the viscosity of the contents is preferably 2 to 300 Pa·s.

[0012] In the present invention, preferably, the container body deforms when pressurized but does not return to its original shape even when the pressurization is stopped.

[0013] The container kit of the present invention includes the above-mentioned nozzle member, a container body that contains the content and to which the nozzle member can be attached to the mouth portion, and a lid member that is detachable from the mouth portion of the container body.

Mode for Carrying Out the Invention

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Figure 1 shows a container kit including a nozzle member according to this embodiment, and Figures 2 and 3 show how the nozzle member is attached to the container body of the container kit. As shown in Figure 1, the container kit 1 of this embodiment includes a tubular container body 2, a lid member 4 attached to the container body 2, and a nozzle member 10 that can be attached to the container body 2. The container kit 1 of this embodiment allows children to draw line drawings on plates, rice, and other food items with the contents, such as curry, by attaching the nozzle member 10 to the container body 2.

[0017] The container body 2 is made of resin, for example, and has a body portion 2A in which the contents are contained, and a mouth portion 2B formed at one end of the body portion 2A. The body portion 2A is cylindrical in shape with one end (the lower end in Figure 1) flat and closed, and the other end (the upper end in Figure 1) tapers toward the mouth portion 2B. The mouth portion 2B is formed in a cylindrical shape with a spiral groove formed on its outer surface. In the unused state, the opening of the mouth portion 2B is sealed by a sheet-like sealing member 2C, and a lid member 4 is attached to the mouth portion 2B.

[0018] Inside the container body 2, for example, a paste-like liquid such as curry is filled. In this embodiment, the paste-like liquid of the content has a viscosity of 2 to 300 Pa·s. This viscosity is a value measured using a viscometer (RB80 type and R100 type manufactured by Toki Sangyo Co., Ltd. in this embodiment) at a measurement temperature of 20°C. By pressing the body portion 2A of the container body 2 from the front and back, the content is discharged from the mouth portion 2B. Note that the container body 2 is configured so that its shape does not return to its original state (i.e., it does not inhale air from the mouth portion 2B) after pressing to discharge the content. Such a configuration can be achieved by adjusting the thickness, material (elasticity), etc. of the portion of the body portion 2A. Thus, when the viscosity of the paste-like liquid of the content is less than 2 Pa·s, the paste-like liquid cannot maintain its shape after being discharged onto a plate or food and will spread. Also, when the viscosity of the paste-like liquid of the content is greater than 300 Pa·s, it becomes very difficult to squeeze out the content from the container body 2. In contrast, when the viscosity of the paste-like liquid of the content is 300 Pa·s, the content can be easily discharged from the container body while maintaining the shape retention property. Furthermore, the viscosity of the content that has the shape retention property necessary for smoothly drawing pictures, patterns, etc. and is preferable because children can easily discharge it is 5 to 50 Pa·s, and the optimal viscosity is 15 Pa·s.

[0019] The lid member 4 is a cylindrical member made of, for example, plastic, etc., with one end closed, and screw threads are formed on the inner peripheral surface. The lid member 4 is attached to the mouth portion 2B of the container body 2 by screwing the screw threads on the inner peripheral surface and the screw threads of the mouth portion 2B of the container body 2.

[0020] The nozzle member 10 is formed in a substantially conical shape, and a through-flow path extending from one end to the lower end along the central axis is formed. One end of the through-flow path (the lower side in FIG. 1) opens downward, and screw threads are formed on the inner peripheral surface of one end of the through-flow path.

[0021] When using container kit 1, rotate the lid member 4 to remove it from the opening 2B, as indicated by arrow I. Then, peel off the sealing member 2C that seals the opening 2B.

[0022] Next, as indicated by arrow II, the nozzle member 10 is positioned so that the opening 2B of the container body 2 is accommodated at one end of the through-flow channel of the nozzle member 10, and the nozzle member 10 is rotated relative to the container body 2. This causes the threads in the through-flow channel of the nozzle member 10 to screw together with the threads on the outer surface of the container body 2, and a container 6 is formed in which the nozzle member 10 is integrated with the container body 2, as shown in Figure 3. In this state, the user holds the container 6 with the nozzle member 10 facing downwards and presses the body 2A of the container body 2, causing the contents inside the container body 2 to pass through the through-flow channel of the nozzle member 10 and be discharged to the outside.

[0023] Next, the nozzle member 10 will be described in detail. Figures 4 to 7 show the nozzle components of the container kit shown in Figure 1, with Figure 4 being a front view, Figure 5 a top view, Figure 6 a bottom view, and Figure 7 a cross-sectional view AA in Figure 4. As shown in Figures 4 to 7, the nozzle member 10 comprises a cylindrical main body portion 14 and a conical portion 12 continuous with the main body portion 14. As shown in Figure 7, the nozzle member 10 has a through-flow channel 20 that extends along the central axis CL from one end (the lower end in Figure 7) to the other end (the upper end in Figure 7).

[0024] The main body 14 has a substantially cylindrical tubular wall portion 14A formed around a central axis CL, and an annular portion 14B extending radially inward from the upper end of the tubular wall portion 14A. A spiral is formed on the inner surface of the tubular wall portion 14A.

[0025] The conical portion 12 is continuous with the inner edge of the annular portion 14B and has a substantially frustoconical (truncate cone) conical wall surface 12A formed around the central axis CL.

[0026] The tip of the through-flow channel 20 (lower end in Figure 7) opens to the end face of the main body 14 as a mounting port 22, and the rear end of the through-flow channel (upper end in Figure 7) opens to the end face of the conical portion 12 as a discharge port 24.

[0027] The through-flow channel 20 comprises a columnar portion 20A surrounded by the cylindrical wall portion 14A of the main body portion 14, and a reduced diameter portion 20B and an expanded diameter portion 20C surrounded by the conical wall surface 12A of the conical portion 12. The columnar portion 20A is located at the tip (upstream end) of the through-channel 20 and is formed in a substantially cylindrical shape. The upstream end of the through-channel 20 is open through the mounting opening 22.

[0028] The reduced-diameter section 20B is continuous with the columnar section 20A on the downstream side and has a circular cross-section in the lateral direction. The reduced-diameter section 20B is formed in a frustoconical shape such that the radius decreases towards the downstream side. The enlarged diameter section 20C is continuous with the reduced diameter section 20B on the downstream side, and its lateral cross-section is circular. The enlarged diameter section 20C is formed in the shape of an inverted frustocone, with the radius increasing towards the downstream side.

[0029] In this embodiment, the reduced-diameter portion 20B and the enlarged-diameter portion 20C are frustoconical and inverted frustoconical, respectively, but the cross-sectional shape of the through-channel 20 is not limited to a circle. However, a rotationally symmetric shape such as a regular polygon is preferred for the cross-sectional shape of the through-channel 20. If the through-channel 20 is a regular polygon, the reduced-diameter portion 20B and the enlarged-diameter portion 20C may be made into regular polygonal frustoconical shapes.

[0030] Figure 8 is a magnified view of the reduced diameter and expanded diameter sections in the cross-sectional view shown in Figure 7. The inventors of the present invention have found that by shaping the expanded diameter section 20C and the reduced diameter section 20B as follows, the contents can be discharged smoothly and the trajectory of the discharged contents will not meander.

[0031] The angle α with respect to the central axis CL of the portion of the inner wall surface of the conical wall surface 12A of the conical portion 12 that forms the enlarged diameter portion 20C is 4° to 45°, and more preferably 4° to 15°.

[0032] Furthermore, the diameter of the upstream end of the enlarged diameter section 20C (i.e., the connection point with the reduced diameter section 20B) is 1.5 mm to 5 mm, more preferably 1.7 mm to 3 mm. That is, the radius R1 of the upstream end of the enlarged diameter section 20C (i.e., the connection point with the reduced diameter section 20B) is 0.75 mm to 2.5 mm, more preferably 0.85 mm to 1.5 mm.

[0033] Furthermore, the diameter of the downstream end of the enlarged diameter section 20C (i.e., the discharge port 24) is 1.7 mm to 6 mm, more preferably 2 mm to 4 mm. That is, the radius R2 of the downstream end of the enlarged diameter section 20C (i.e., the discharge port 24) is 0.85 mm to 3 mm, more preferably 1 mm to 2 mm. By setting the diameter of the downstream end of the enlarged section 20C (i.e., the discharge port 24) to 2 mm to 4 mm, the squeezed-out contents become a thin line, allowing for the creation of delicate lines and drawings.

[0034] Furthermore, the length D1 along the central axis CL of the enlarged diameter portion 20C is 1 mm to 8 mm, and more preferably 2 mm to 4 mm.

[0035] The diameter of the upstream end of the reduced-diameter section 20B (i.e., the connection point with the columnar section 20A) is 5 mm to 30 mm, more preferably 5 mm to 10 mm. That is, the radius R3 of the upstream end of the reduced-diameter section 20B (i.e., the connection point with the columnar section 20A) is 2.5 mm to 15 mm, more preferably 2.5 mm to 5 mm. You should match the diameter of the opening of the tube container you are using.

[0036] According to the present invention with the above configuration, the through-flow channel 20 of the nozzle member 10 includes a diameter-reducing section 20B that narrows in a frustoconical shape toward the discharge port 24, and a diameter-expanding section 20C provided downstream of the diameter-reducing section 20B that widens in an inverted frustoconical shape toward the discharge port 24. Since the inner surface of the diameter-expanding section 20C is inclined at an angle of 4° to 45° with respect to the central axis CL, it is possible to prevent the drawn line from meandering when attempting to draw a straight line with the contents discharged from the nozzle member 10. More specifically, when a diameter-reducing section 20B is provided within the through-flow channel 20 as in this embodiment, the contents concentrate downstream of the diameter-reducing section 20B, and pressure is applied at the downstream end of the diameter-reducing section 20B, resulting in a very large flow velocity of the contents during discharge. For this reason, if a small-diameter discharge port is provided at the downstream end of the diameter-reducing section 20B, or if a small-diameter cylindrical section is continuously formed downstream of the diameter-reducing section 20B, the force acting on the contents in this small-diameter section becomes large. Furthermore, at the moment of discharge from the discharge port, the pressure acting on the contents is suddenly released over a wide angular range, and the discharge direction of the highly viscous contents is not fixed, causing meandering. This meandering is less likely to occur when the viscosity of the contents is low and close to a liquid, but is more likely to occur when discharging contents with a viscosity of 2 Pa·s or more, especially 5 Pa·s or more, as in this embodiment. In contrast, according to this embodiment, the through-flow channel 20 is provided downstream of the narrowed diameter section 20B and includes an expanding diameter section 20C that expands in an inverted frustoconical shape toward the discharge port 24. As a result, the pressure acting on the contents gradually decreases as it moves downstream, rather than being released all at once. The highly viscous contents are then guided and rectified by the inner wall of the expanding diameter section 20C, restricting their movement in unspecified directions and allowing them to be smoothly discharged in one direction from the discharge port. However, if the angle of the inner wall of the enlarged section 20C with respect to the central axis CL is too small, the force acting on the contents as they flow through the enlarged section 20C will not decrease significantly, and when discharged from the outlet, a large pressure will act on the contents in all directions, making it impossible to adequately prevent meandering. Furthermore, if the angle of the inner wall of the enlarged diameter section 20C with respect to the central axis CL is too large, the pressure acting on the contents will be suddenly released when the contents pass through the connection between the reduced diameter section 20B and the enlarged diameter section 20C, causing the contents to meander as if the enlarged diameter section 20C were not provided. In contrast, in this embodiment, the inner surface of the enlarged diameter portion 20C is inclined at an angle of 4° to 45° with respect to the central axis CL, so that when the contents discharged from the nozzle member 10 are used to draw a straight line, the drawn line does not meander. [Examples]

In Example 15, the curry trajectory was perfectly straight with no meandering not only when the container body 2 was pressed slowly, but also when it was pressed rapidly. In Example 16, when the container body 2 was pressed slowly, there was a slight meandering in the curry trajectory, but it was not significant enough to cause problems during drawing.

[0062] <Third Example> Furthermore, in order to determine the appropriate dimensions of the nozzle in this embodiment, nozzles according to Examples 21-37 and Comparative Examples 21-23 of the present invention were manufactured, and experiments were conducted in which each nozzle was attached to a container body filled with curry as the contents, and the curry was dispensed.
