Pour cap

Abstract

To disclose a technique of generating neither liquid dropping nor scattering when erecting a bottle from pouring out a content, according to a spouting cap with a nozzle.SOLUTION: A land part 17 swollen upward is formed on a top wall 7 of a body 1, and a nozzle 18 is protrusively provided on the land part 17. Since the land part 17 is narrowed upward, a content 23 can be guided to the nozzle 18 during spouting. Since the nozzle 18 is provided on the land part 17, the content can be accurately spouted to an aimed site such as a plate by increasing a height of an upper end of the nozzle 18. Since a straight part 21 of the nozzle 18 is short, a phenomenon by which a film of the content 23 is produced in the nozzle 18 when erecting a bottle 4 after spouting is not generated. Thus, scattering of the content 23 can be prevented by preventing a phenomenon that the film bursts after being spheroidized. Further, since the content 23 as a whole returns in a lump state, no liquid dropping is generated.SELECTED DRAWING: Figure 10

Description

Technical Field

[0001] The present invention relates to a pouring cap for pouring the contents from a nozzle.

Background Art

[0002] As one aspect of the pouring cap, there is a type in which a nozzle is provided protruding from the main body and the contents are poured (dispensed) from the nozzle. In this type, the bottle (container) is generally configured to be deformable by synthetic resin, and the bottle is often pressed by hand to eject the contents from the nozzle. For example, it is widely used for packaging high-viscosity seasonings such as ketchup, sauce, mayonnaise, liquid miso, and sauces (e.g., sauce for grilled meat). The bottle may be in a tube shape.

[0003] In this type of pouring cap, there is a problem that the phenomenon of "liquid dripping" where the contents drip from the tip of the nozzle easily occurs after pouring the contents. Therefore, it has been proposed to provide a flange at the upper end (opening edge) of the nozzle to prevent liquid dripping.

[0004] As an example thereof, Patent Document 1 discloses that while forming the nozzle at the same height over the entire circumference, a flange is uniformly formed over the entire circumference of the upper end. That is, in Patent Document 1, the nozzle is formed in a simple trumpet shape.

[0005] On the other hand, in Patent Document 2, in a hinge cap in which the lid is integrally formed with the main body via a hinge, it is disclosed that the upper surface of the nozzle is inclined so as to become lower as it approaches the hinge, and a flange is formed at the higher part. Further, in Patent Document 3, in a hinge cap in which the lid is integrally formed with the main body via a hinge as in Patent Document 2, while the upper surface of the nozzle is inclined so as to become lower as it approaches the hinge, a flange is formed over the entire circumference of the opening edge of the nozzle.

[0006] In Patent Documents 2 and 3, the fact that the upper surface of the nozzle is sloped so that it becomes lower as it approaches the hinge (or higher as it moves away from the hinge) is primarily intended to facilitate the insertion of the sealing projection provided on the lid into the inside of the nozzle. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Application Publication No. 08-86552 [Patent Document 2] Japanese Patent Publication No. 2013-154934 [Patent Document 3] Japanese Patent Publication No. 2020-19482 [Overview of the project] [Problems that the invention aims to solve]

[0008] The problem of liquid dripping is a widespread issue with dispensing caps, but with nozzle-equipped dispensing caps, when the contents are a highly viscous liquid such as liquid miso, when the bottle is inverted after dispensing, a balloon-like sphere of contents may form at the opening edge of the nozzle. This sphere can instantly burst, scattering and staining tables or people's clothes. This phenomenon also occurs when the top surface of the nozzle is inclined, as described in Patent Documents 2 and 3.

[0009] The exact mechanism by which a sphere is formed and bursts when the bottle is inverted has not been fully elucidated. However, it is presumed that when the bottle is inverted, a film of the contents forms due to the surface tension, covering the opening edge of the nozzle, because the high viscosity of the contents results in high surface tension. This film then changes into a sphere due to the negative pressure created when the bottle is released from pressure. However, the surface tension is not strong enough to maintain the sphere, so it bursts at the same time as it forms, scattering the contents into the surrounding area.

[0010] The present invention was made against this backdrop, and aims to disclose a dispensing cap that can suppress the phenomenon of contents scattering after dispensing. [Means for solving the problem]

[0011] The present invention includes various configurations, and typical examples are specified in each claim. Of these, the invention of claim 1 is: "The bottle has a body that is fitted into the neck of the bottle with a stopper or screwed in, and the body comprises a cylindrical portion that attaches to the neck of the bottle and a top wall provided at its upper end, with a nozzle protruding from the top wall." In this basic configuration, "The top wall has an upwardly bulging land portion, and the nozzle is provided on the land portion." It possesses the following characteristics.

[0012] The invention of claim 2 is, in claim 1, "It is equipped with a lid that is formed integrally with or separately from the main body." This is the configuration. The lids include those connected by hinges and those that are detachable, such as screw-on lids. The invention of claim 1 also includes dispensing caps that do not have lids.

[0013] The invention of claim 3 is, in claim 1 or 2, "The land portion has an upwardly concave and curved cross-sectional shape that narrows upward, the highest point on which the nozzle is provided is eccentric to the axis of the main body, and the portion of the land portion located on the opposite side of the axis of the main body with respect to the nozzle is steeper in slope than the portion located on the side of the axis of the main body with respect to the nozzle." This is the structure.

[0014] The invention of claim 4 is as described in claim 3, "The lid is integrally attached to the main body via a hinge, The nozzle is positioned offset from the hinge, with respect to the axis of the main body, The lid is provided with a sealing projection that fits onto and disengages from the nozzle of the main body when the lid is opened and closed. It has such a configuration.

[0015] As a development example of any one of claims 1 to 4, in claim 5, "The upper surface of the nozzle is set to the same height over the entire circumference." It has such a configuration. As a development example of claim 3 or 4, in claim 6, "The upper surface of the nozzle is inclined so as to become higher as it moves away from the axis of the main body." It has such a configuration. In claim 7, "The upper surface of the nozzle is inclined so as to become lower as it moves away from the axis of the main body." It has such a configuration.

[0016] In the present invention, when a lid connected by a hinge is provided, as in Patent Documents 1 to 3, it is possible to provide a sealing projection on the lid that fits inside the nozzle. Alternatively, it is also possible to provide a sealing boss body that surrounds the nozzle on the main body and a cylindrical projection that fits onto the sealing boss body on the lid.

Effects of the Invention

[0017] Now, in order to pour the contents out onto a targeted site (target site) such as a plate, a certain height is required for the nozzle. And in each of the patent documents, the top wall is flat and the nozzle is erected therefrom. Therefore, the nozzle has a certain length. Due to the nozzle being long like this, it is presumed that when the bottle is lifted, the return of the contents is poor and a film of the contents is likely to form at the opening edge of the nozzle.

[0018] In contrast, in the invention of the present application, since the nozzle is provided on the land portion, while making the upper end of the nozzle at a height where there is no hindrance to use, the length of the nozzle can be made as short as possible. As a result, when the bottle is lifted, the content can easily return to the inside of the bottle, and the formation of a film on the opening edge of the nozzle can be prevented or significantly suppressed. Thereby, it is possible to prevent or significantly suppress the content from becoming spherical and then bursting and soiling the surroundings.

[0019] When a lid is provided as in claim 2, it is possible to prevent dirt during non-use. In particular, since the pouring cap of the present invention is often used for bottles packaging foods such as seasonings, the role of preventing dirt is important.

[0020] When the nozzle is offset with respect to the axis of the main body as in claim 3, when pouring out the content by tilting the bottle, the nozzle can be brought as close as possible to the target portion, so that it is easy to aim at the flying position of the content. Also, dripping of the liquid when the bottle is lifted after pouring out the content can be suppressed.

[0021] Although the bulging mode of the land portion can be embodied in various ways, when it is formed in a cross-sectional shape that is concave and curved upward as in claim 3, it is understood that when pouring out the content, the content is smoothly guided toward the nozzle.

[0022] And since the land portion spreads widely on the side of the axis of the main body, the land portion becomes steeply inclined on the side opposite to the axis of the main body. Due to such a steep inclination, the same effect as when the content is formed long appears, and the straightness when pouring out the content can be enhanced, and the content can be accurately poured out to the targeted part.

[0023] When embodied as a hinge cap as in claim 4, the lid has the advantage of being able to open and close in a watertight manner. In this case, when the upper surface of the nozzle is inclined as in claims 6 and 7, it is suitable because it can facilitate the insertion and detachment of the sealing protrusion.

[0024] Furthermore, by setting the upper end surface of the nozzle to the same height as in claim 5, the function of returning the contents remaining at the mouth of the bottle to the container as a whole when the bottle is upright after pouring out the contents is improved. As a result, there is an advantage in that the contents can be prevented or suppressed when the container is upright after pouring out the contents. [Brief explanation of the drawing]

[0026] (1) Structure of the first embodiment Next, embodiments of the present invention will be described based on the drawings. First, the first embodiment shown in Figures 1 to 4 will be described. This embodiment is applied to a hinged cap. Therefore, the dispensing cap consists of a main body 1 and a lid 3 integrally connected thereto via a hinge 2.

[0027] The main body 1 comprises an outer cylinder 5 that fits onto the neck of the bottle 4 from the outside, an inner cylinder 6 that fits onto the neck of the bottle 4 from the inside, and a top wall 7 connected to the upper ends of both. The lid 3 is integrally connected to one side of the outer cylinder 5 via a hinge 2. The hinge 2 consists of a wide center hinge 2a and a narrow side hinge (film hinge) 2b.

[0028] An annular frame 8 is formed on the top wall 7 of the main body 1, slightly recessed from its outer circumference. An outward-facing engaging portion 9 is formed on the annular frame 8. On the other hand, a material-removing step 10 is formed on the opening edge of the cylindrical portion of the lid 3 into which the annular frame 8 of the main body 1 fits, and an inward-facing engaging portion 11 is formed on the material-removing step 10 that engages with the engaging portion 9 of the annular frame 8.

[0029] A tab 12 is provided on the cylindrical portion of the lid 3 opposite the hinge 2, for gripping with the fingertips when opening. Furthermore, a recess 13 is formed on the outer surface of the main body 1 to improve the grip of the tab 12. The outer cylinder 5 constituting the main body 1 has an inward-facing annular projection 15 that engages with the outward-facing annular recess 14 on the neck of the bottle 4. Therefore, the main body 1 is forcibly fitted (sealed) using elastic deformation.

[0030] Furthermore, on the outer part of the annular frame 8 of the main body 1, an upward-facing opening groove 16 is formed over a wide area excluding the recess 13, which reduces the connection strength between the outer cylinder 5 and the top wall 7, thereby facilitating detachment from the neck of the bottle 4. When the open lid 3 is pulled upward, the outer cylinder 5 tears vertically, and then when the lid is pulled circumferentially, it breaks at the connection point (weakened part) between the main body 1 and the top wall 7, where the upward-facing opening groove 16 is located, thereby releasing the engagement of the outer cylinder 5 with the neck of the bottle 4. Consequently, the main body 1 can be easily removed from the bottle 4.

[0031] A land portion 17 that bulges upward is formed on the top wall 7 of the main body 1. The land portion 17 has a mountain-like shape that narrows towards the part offset to the opposite side of the hinge 2, and the entire upper surface has an upward-concave curved surface. A nozzle 18 is projected from the highest point located on the opposite side of the hinge 2. Therefore, the nozzle 18 is offset (eccentric) from the hinge 2 across the axis of the main body 1.

[0032] Furthermore, due to the eccentricity of the nozzle 18, the cross-section of the land portion 17 has a gently sloping portion 17a on the side of the hinge 2 with the nozzle 18 in between, and a steeply sloping portion 17b on the side of the nozzle 18 opposite the hinge 2. (Steeply sloping portion 17b and nozzle 18) It is a smooth continuation.

[0033] The upper surface 18a of the nozzle 18 is sloped such that its height increases as it moves away from the hinge 2, and a flange 19 is formed mainly on the side opposite the hinge 2. It goes without saying that the flange 19 guides the flow of the contents and prevents dripping, and its thickness decreases towards the tip.

[0034] The inner surface of the opening edge of the nozzle 18 has a chamfered relief surface 20, and a straight section 21 is located below the lowest end of the relief surface 20. A sealing projection 22 that tightly fits with the straight section 21 is formed on the lower surface of the top plate that constitutes the lid 3. The sealing projection 22 is formed in a cylindrical shape, but it may also be formed in a solid shape (round rod shape, pin shape).

[0035] (2).Effect Bottle 4 is made of a synthetic resin such as PET, and as shown in Figure 3(B), the contents 23 can be poured out by tilting bottle 4 with the lid 3 facing upwards. Typically, the contents 23 are ejected by pressurizing bottle 4.

[0036] In this embodiment, the entire land portion 17 is formed in a mountain shape that narrows towards the nozzle 18, so that the contents 23 are guided toward the nozzle 18 by the land portion 17 during dispensing. This allows for smooth dispensing of the contents 23.

[0037] Furthermore, since the nozzle 18 is located on the land portion 17, the distance (height) from the top wall 7 to the upper end of the land portion 17 is increased. This, combined with the fact that the nozzle 18 is eccentrically positioned from the axis of the main body 1, allows the tip of the nozzle 18 to be brought as close as possible to the target area such as a plate. Therefore, the ease of spraying the contents onto the target area of ​​the plate (or food) is not impaired.

[0038] Then, when the bottle 4 is turned upright after dispensing, the contents 23 that had accumulated in the nozzle 18 return to the bottle 4. However, because the pressure in the bottle 4 is released and it becomes a negative pressure state, the contents 23 tend to be drawn into the inside of the bottle 4.

[0039] In this case, conventionally, as schematically shown by the dotted line in Figure 4, a film 24 of the contents 23 was formed to cover the upper surface 18a of the nozzle 18, and this film would sometimes become spherical and burst instantaneously. This is presumed to be because, when the nozzle 18 is long, the flow resistance on the inner surface of the nozzle 18 is large, causing a portion of the contents 23 remaining in the nozzle 18 to remain covering the upper surface 18a of the nozzle 18 due to surface tension. Although it becomes spherical due to the negative pressure in the bottle 4, it cannot maintain its spherical shape and bursts instantaneously.

[0040] In contrast, in this embodiment, the nozzle 18 is located at the highest point of the land portion 17, so the height is increased while the vertical length is shorter than in the conventional design. Consequently, the flow resistance when the contents 23 return is significantly reduced. As a result, as shown in Figure 4, the contents 23 that had returned to the nozzle 18 return entirely to the bottle 4 due to the negative pressure created in the bottle 4 (or due to its own weight). Therefore, no film 24 is formed on the upper surface 18a of the nozzle 18, and no scattering phenomenon occurs due to the rupture of the sphere.

[0041] Therefore, without compromising the ease of precisely dispensing the contents onto a target area such as a plate by increasing the height of the nozzle 18, it is possible to prevent the small particles of the contents 23 from scattering when the bottle 4 is raised.

[0042] In this embodiment, the land portion 17 has a curved shape like an inverted trumpet, but it is also possible to form it in a tapered shape where the cross-sectional shape appears as a straight line. In this case as well, the same function and effect as described above will be achieved.

[0043] (3) Second to eighth embodiments Next, embodiments shown in Figure 5 and following will be described. In the second embodiment shown in Figure 5, the steeply inclined portion 17b of the land portion 17, located on the opposite side of the hinge 2 with the nozzle 18 in between, is formed as a curved surface that bulges outward (concave inward). When formed in this way, the contact area with the inner surface of the nozzle 18 is reduced when the contents 23 remaining in the nozzle 18 after dispensing returns to the bottle 4. This ensures the rapid return of the contents 23 and significantly improves the effect of preventing the contents 23 from scattering.

[0044] In the third embodiment shown in Figures 6(A) and 6(B), the land portion 17 is formed in a trapezoidal (or rectangular) cross-section with a flat upper surface 17c. It is also elongated in the direction of alignment between the main body 1 and the lid 3 (the direction perpendicular to the opening and closing pivot axis of the lid 3). On the other hand, in the fourth embodiment shown in Figure 6(C), the land portion 17 is curved in the opposite direction to the first embodiment, bulging upward (concave inward). That is, in the fourth embodiment of Figure 6(C), the land portion 17 is formed in a dome shape.

[0045] In the fifth embodiment shown in Figure 7, the upper surface 18a of the nozzle 18 is inclined to become lower in the direction away from the hinge 2. That is, the inclination of the nozzle 18's 18a is the opposite of that in the previous embodiments. The portion of the nozzle 18's opening edge closest to the hinge 2 is a widened portion 25 that is inclined toward the hinge 2. This is to suppress interference with the sealing projection 22 of the lid 3. In this embodiment, the land portion 17 is applied to the third embodiment, but it can also be applied to other embodiments.

[0046] As mentioned with reference to Figure 4, in the conventional structure, a film 24 is easily formed on the opening surface of the nozzle 18. It is speculated that the ease of forming the film 24 may also be related to the shape of the upper surface 18a of the nozzle 18.

[0047] In other words, conventionally, the upper surface 18a of the nozzle 18 is either at the same height throughout without any inclination, or it is inclined to become lower toward the hinge 2 (the same applies to the first to fourth embodiments of the present application). On the other hand, as shown by the arrow 26 in Figure 4, when the bottle 4 is raised after dispensing is complete, the contents 23 remaining in the nozzle 18 move back into the inside of the bottle 4. However, in the conventional structure, the contents 23 tend to move along the upper surface (opening edge) 18a of the nozzle 18, so it is presumed that the contents 23 tend to spread across the entire upper surface 18a of the nozzle 18, and a film 24 is likely to be formed.

[0048] On the other hand, if the upper surface 18a of the nozzle 18 is tilted in the opposite direction to the conventional method, as in the fifth embodiment shown in Figure 7 of this application, the upper surface of the nozzle 18 is higher in the direction of return of the contents 23. Therefore, due to the law of gravity, it is difficult for the contents 23 to spread across the entire upper surface 18a of the nozzle 18. Consequently, it is understood that the entire contents 23 remaining in the nozzle 18 can be quickly returned to the bottle 4.

[0049] In the sixth embodiment shown in Figure 7(C), a wall 27 is erected on the side of the nozzle 18 closer to the hinge 2. This is also expected to prevent the formation of a film and thus prevent the scattering of the contents 23.

[0050] In the seventh embodiment shown in Figure 8, a partition plate 28 is provided inside the nozzle 18, dividing the interior in the direction of the pivot axis of the hinge 2, thereby separating the interior of the nozzle 18 into two spaces, left and right. Meanwhile, the lid 3 is provided with a pin 29 with a semicircular cross-section that fits into and out of the two spaces of the nozzle 18. The upper end of the partition plate 28 is formed in the shape of a sharp edge.

[0051] Furthermore, in this embodiment, as a sealing means, an upward-facing sealing boss 30 is provided protruding from the area around the nozzle 18 of the land portion 17, while a cylindrical projection 31 that fits onto the sealing boss 30 is provided on the top plate of the lid 3. The cylindrical projection 31 is tightly fitted onto the sealing boss 30 from the outside, but it may also be tightly fitted from the inside.

[0052] In this embodiment, since the upper end of the partition plate 28 has a sharp edge, it can be said that it is possible to reliably prevent a film from forming on the upper surface 18a of the nozzle 18. In addition, although the contents 23 adhere to the inner surface of the nozzle 18, the adhered contents can be scraped off with the pin 29 and returned to the inside of the bottle 4.

[0053] In previous embodiments, the land portion 17 was formed to extend over a wide area of ​​the top wall 7, but in the eighth embodiment shown in Figure 9, the land portion 17 is partially formed on the part of the top wall 7 that is far from the hinge 2. Even in this configuration, the same functions and effects as in the first embodiment can be achieved. The land portion 17 is formed in a dome shape, but it is also possible to form it in a tapered shape or, conversely, curve it (as in the first embodiment).

[0054] (4) Embodiments 9-13 Figure 10 shows an embodiment corresponding to claim 5. This embodiment has the same basic structure as the first embodiment, and the differences from the first embodiment are that the steeply inclined portion 17b of the land portion 17 has a straight cross-sectional shape instead of a curled structure, and the upper surface 18a of the nozzle 18 is at the same height all around. In this embodiment, the relief surface 20 at the upper end of the nozzle 18 is a curved surface that bulges inward all around, with almost no outward overhang. In other words, it can be said that the flange 19 of the first embodiment does not exist, but this does not mean that the outwardly protruding flange 19 is eliminated.

[0055] Now, as in the first embodiment, when the upper surface 18a of the nozzle 18 is inclined, the contents sometimes drip when the bottle is raised after the contents have been poured out. The inventors of the present invention have researched this point and have found that, as shown in Figure 10(D), when the upper surface 18a is inclined, the contents 23 that remained in a lump at the mouth of the nozzle 18 due to surface tension do not return to the bottle as a whole, and a part of the lump remains protruding outside the nozzle 18, which then drips down.

[0056] In other words, when the contents 23 are poured out and the bottle 4 is turned upright, as shown in Figure 4(A), the contents 23 return to the inside of the bottle 4 with some of it remaining in the nozzle 18. In this case, the portion of the contents 23 remaining in the nozzle 18 becomes a solid mass due to surface tension, and some of the contents 23 may protrude outside the nozzle 18. However, the surface tension of the contents 23 is not necessarily strong, and if the upper surface 18a of the nozzle 18 is inclined, as shown in Figure 10(D), the contents 23 does not fill the nozzle 18 but immediately flows down into the inside of the bottle. As a result, the contents 23 separates into the portion 23a that protrudes from the nozzle 18 and the main body portion 23b that flows down into the inside of the bottle 4, and it is presumed that the portion 23a that protrudes from the nozzle 18 drips downwards.

[0057] To elaborate further, if the bottle is made of plastic, a person pressurizes the bottle to dispense the contents, and then releases the pressure when returning the bottle to its original position. As a result, when the bottle is returned to its original position, negative pressure is created inside the bottle. Because of this negative pressure, the main body portion 23b of the clumped contents 23 quickly returns to its original position. Consequently, the surface tension that holds the contents 23 in a clump is overcome by the tensile force of the main body portion 23b, causing the clump to split in two, and the portion 23a that was protruding from the nozzle 18 is more likely to drip out.

[0058] In contrast, as in this embodiment, when the upper surface of the nozzle 18 is set to the same height, as shown in Figure 10(C), the flow resistance increases as the contents 23 flows down from the nozzle 18. As a result, clumps of contents 23 are held inside the nozzle 18 for a certain period of time. This maintains the state in which the contents 23 are held together as a whole by surface tension, and as a result, all of the contents 23 remaining at the opening of the nozzle 18 return to the inside of the bottle 4, significantly improving the dripping phenomenon.

[0059] In other words, in this embodiment, the contents 23 remaining in the nozzle 18 are prevented from flowing excessively, and the contents 23 can be returned to the bottle 4 while remaining in a solid state due to surface tension. This significantly improves the phenomenon of the contents 23 dripping.

[0060] Furthermore, this embodiment, by including the land portion 17, makes it easier for the contents to return to the inside of the bottle 4 when the bottle 4 is raised, preventing or significantly suppressing the formation of a film on the opening edge of the nozzle 18 and significantly improving the scattering phenomenon of the contents 23. Moreover, this embodiment allows the contents 23 to be quickly returned in a solid state, thereby preventing or significantly suppressing both the dripping and scattering phenomena of the contents 23.

[0061] Each embodiment shown in Figure 11 also embodies claim 5. In the tenth embodiment shown in Figure 11(A), the relief surface 20 of the nozzle 18 is formed as a tapered surface around its entire circumference. On the other hand, in the eleventh embodiment shown in Figure 11(B), the outlet portion 20a of the relief surface 20 from which the contents 23 flow out is formed as an inwardly concave curved surface, while the portion of the contents 23 opposite the outlet portion 20a is formed as an inwardly bulging curved surface. Therefore, the shape of the relief surface 20 gradually changes in the circumferential direction.

[0062] In the twelfth embodiment shown in Figures 11(B) and 11(C), first, the outflow portion 20a of the relief surface 20 of the nozzle 18 is formed as a tapered surface, and the portion of the relief surface 20 opposite to the outflow portion 20a is formed as an inwardly bulging curved surface. Furthermore, as a unique configuration, an auxiliary wall portion 32 is formed on the inner surface of the nozzle 18 opposite to the outflow portion 20a, which is an extension of the inner surface of the straight portion 21 downwards. Consequently, an inwardly recessed recess 33 is formed in the gently sloping portion 17a of the land portion 17.

[0063] In this embodiment, the auxiliary wall portion 32 acts as resistance against the return of the contents 23, thereby enhancing the function of keeping the contents 23 remaining in the nozzle 18 in a solid state after dispensing. Consequently, the effect of preventing dripping after dispensing can be enhanced.

[0064] In the 12th embodiment, a recess 33 is formed in the gently sloping portion 17a of the land portion 17 to form an auxiliary wall portion 32. However, in the 13th and 14th embodiments shown in Figure 12, the auxiliary wall portion 32 is formed by providing a rib protruding from the base of the nozzle 18. In the 14th embodiment (A) in Figure 12, the upper surface 18a of the nozzle 18 is at the same height all around, while in the 14th embodiment (B), the upper surface 18a of the nozzle 18 is a sloped surface that is lower on the side of the hinge 2. In all embodiments, the function of maintaining the contents 23 in a solid state when the bottle 4 is raised is excellent, and it can be said that dripping can be effectively prevented.

[0065] The embodiments of the present invention have been described above, but the present invention can be implemented in various other ways. For example, the dispensing cap can be a screw-on type that is screwed onto the bottle. In the present invention, the bottle also includes tube containers.

[0066] Furthermore, each of the dispensing caps presented in this application has an unprecedented form and is superior in terms of design. Therefore, each form may be eligible for design registration, and in that case, registration of only the land portion and the nozzle portion (registration as a partial design) is also possible. A flange may be provided around the entire circumference of the nozzle, and the upper surface may be inclined as in the first and fifth embodiments. [Industrial applicability]
