Description

[Technical Field]

[0001] The present invention relates to a dispensing container made of synthetic resin, and more particularly to a dispensing container comprising a container body and a hinged cap attached to the container body. [Background technology]

[0002] Conventionally, synthetic resin dispensing containers with a hinged cap attached to the mouth of the container body, which comprises a cap body and an upper lid attached to the cap body via a hinge so as to be openable and closable, have been widely used as dispensing containers for various types of seasonings, etc.

[0003] As a prior art for a polyethylene terephthalate (PET) dispensing container in which a hinge cap is attached to the mouth of the container body by a stopper, a dispensing container having a mouth structure in which a mouth having a ring-shaped engaging ridge protruding from the outer periphery is fitted into a fitting groove in the hinge cap, and the fitting groove clamps the mouth, thereby attaching and fixing the hinge cap to the mouth (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-225836 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the dispensing container described in Patent Document 1, although the hinge cap made of polyethylene (PE) or polypropylene (PP) can be disposed of separately from the PET container body, there was a problem in that the amount of resin used to mold the hinge cap was large, and the proportion of PET that needed to be recycled was low compared to the amount of resin in the hinge cap that was discarded.

[0006] The present invention aims to solve the above problems and to provide a dispensing container consisting of a container body and a hinged cap that is attached to the container body and closes the mouth of the container body, in which the amount of resin in the hinged cap can be reduced. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a pouring container comprising: Made of polyethylene terephthalate The container body and the nozzle are attached to close the nozzle. Made of polyethylene or polypropylene The dispensing container is composed of a hinged cap, and the hinged cap has a cap body that is attached to only a portion of the spout, and an upper lid that is connected to the cap body via a hinge, the cap body has an attachment base formed only on the hinge side and an engagement piece provided on the attachment base, and the container body has a nozzle portion that stands upright from the upper end of the spout, and an insertion opening portion into which the engagement piece is inserted on the outer periphery of the spout.

[0008] In one embodiment of the dispensing container, the engaging piece has a vertical engaging piece hanging down from the mounting base and a locking protrusion protruding horizontally from the vertical engaging piece, and the insertion opening has a top opening into which the vertical engaging piece is inserted and a side opening into which the locking protrusion fits; the engaging piece has a horizontal engaging piece extending horizontally from the mounting base and a locking protrusion protruding vertically from the horizontal engaging piece, and the insertion opening has a side opening into which the horizontal engaging piece is inserted and a top opening into which the locking protrusion fits.

[0009] As a specific embodiment of the dispensing container, a configuration is adopted in which the upper lid has a top wall and a sealing tube hanging down from the underside of the top wall to seal the nozzle portion, and the sealing tube has a sealing portion that is inserted into the expanded inner surface of the nozzle portion to create a sealed state when the lid is closed, and a lower sealing tube is provided on the lower outer periphery of the sealing tube, which has a stepped portion on the lower inner periphery of the nozzle portion when the lid is closed, and the lower sealing tube is close to or abuts against the reduced inner surface, which has a stepped portion on the lower inner periphery of the nozzle portion, and a temporary seal is formed between the lower sealing tube and the inner surface. [Effects of the Invention]

[0010] In the pouring container of the present invention, the cap body of the hinged cap that is attached to the mouth portion of the container body is attached to the mouth portion of the container body only on the hinge side, so the hinged cap can be molded using a smaller amount of resin than conventional ones. This reduces the amount of resin that must be separated for disposal after use of the pouring container, and also increases the amount of recyclable PET that can be recycled.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Embodiments of the present invention will now be described with reference to the drawings, which are shown by way of example only. In the following description, the left direction in FIG. 2(a) is referred to as the "front", the right direction as the "rear", the upper direction as the "top", and the lower direction as the "bottom". [Example]

[0013] In FIGS. 1 and 2, A denotes a container body, and B denotes a hinged cap that is attached to a nozzle 1 of the container body A and closes the nozzle 1.

[0014] As shown in Figures 1 to 3, the container body A has a cylindrical mouth portion 1 at the top, and the inner periphery of the mouth portion 1 is formed with a spout portion 2 consisting of an inner circumferential surface 2a that continues from below and an expanded-diameter inner circumferential surface 2c that expands in diameter from the upper end of the inner circumferential surface 2a via a step portion 2b, and a nozzle portion 3 is erected at the upper end of the mouth portion 1, the inner circumferential surface of which communicates with the expanded-diameter inner circumferential surface 2c.

[0015] On the outer periphery of the nozzle portion 1, there is formed an outer wall portion 4 to which a hinged cap B is attached at the lower back side, and a lid engagement portion 5 on the upper front side of the outer wall portion 4 (in the drawing, within a 180° range opposite the hinge B2) that engages with the hinged cap B to maintain the closed state. As shown in Figure 3, an insertion opening 6 is formed in a predetermined angle range θ on the rear side of the nozzle portion 1, with a width d1 from a predetermined distance on the rear side of the nozzle portion 3 to the outer periphery of the outer wall portion 4 connected to it, and a predetermined height range h1 from the upper end of the lid engagement portion 5 to the outer wall portion 4, for inserting the cap body B1 of the hinged cap B described below. A lid locking projection 7 is provided on the lid engaging portion 5 at a predetermined range on the front side of the upper outer periphery thereof.

[0016] The insertion opening 6 is cut into the lid engagement portion 5 and the outer wall portion 4 at an angle θ of approximately 90° centered on the back side, and consists of side end faces 6a on both sides, a rear side face 6b, and a bottom face 6c formed on the outer wall portion 4, and is formed in a C-shape when viewed from above, and an engagement wall portion 8 is formed between the side end faces 6a on both sides of the outer wall portion 4 and connected to them in a C-shape on the outer side. When viewed from above, the inner surface of the engagement wall portion 8 is spaced a predetermined width d2 from the rear side surface 6b, a C-shaped upper surface opening 9 is formed in between, and the outer surface is formed so as to be flush with the outer surface of the outer wall portion 4.When viewed from the back, it is formed at a height range h4 at a position a predetermined height range h2 below the upper end of the outer wall portion 4 and a predetermined height range h3 above the bottom surface 6c, forming a side surface opening 10 therebetween (h4>h2 and h3).

[0017] In this embodiment, the nozzle portion 3 is formed in a cylindrical shape, and in order to make it easier to pour the contents, the front side, which is the pouring direction, is formed higher than the back side, and the tip has a lip portion 3a that widens like a trumpet.

[0018] As shown in Figures 1, 2 and 4, the hinged cap B comprises a cap body B1 that is attached to the insertion port portion 6 of the container body A, and an upper lid B3 that is connected to the cap body B1 via a hinge B2 and that opens and closes the pouring outlet portion 2.

[0019] The cap body B1 is formed in a shape (C-shaped with an angle range θ of approximately 90° centered on the back side) that fits into the insertion opening 6 of the container body A when viewed from above, and is equipped with an attachment base 15 to which a hinge B2 is connected at the upper end of its outer periphery, a vertical engagement piece 16 that hangs down from the inner side of the attachment base 15 and fits into the top opening 9, and a locking protrusion 17 that protrudes from the lower part of the outer periphery of the vertical engagement piece 16 and whose upper edge engages with the inner peripheral edge of the lower end of the engagement wall portion 8.

[0020] The mounting base 15 is formed at a height within a height range h2 from the upper end, and when mounted, its upper surface and outer peripheral surface are flush with the upper surface and outer peripheral surface of the outer peripheral wall portion 4, and its lower surface abuts against the upper surface of the engagement wall portion 8. The vertical engagement piece 16 is formed to a length that falls within the height range h3+h4 (as shown in the figure, there may be a gap between the lower end surface of the vertical engagement piece 16 and the bottom surface 6c, or they may be made to abut). The height of the locking projection 17 is formed within a height range h3.

[0021] The upper cover B3 comprises a top wall 20, a side peripheral wall 21 that hangs down from the peripheral edge of the top wall 20 and has a hinge B2 connected to the back side of the lower end of the outer periphery, and a sealing tube 22 that hangs down from the underside of the top wall 20. On the front side of the side wall 21, a locking recess 23 is provided at the lower inner end, which is recessed in a shape that engages with the lid locking protrusion 7 of the lid engagement portion 5 of the container body A when the lid is closed to maintain the closed state, and an arc-shaped finger hook portion 24 is provided at the lower outer end.

[0022] As shown in Figure 2(b), the sealing tube 22 has a normal sealing portion Sa formed so that the lower outer periphery is inserted into the upper part of the enlarged inner periphery 2c of the spout portion 2 of the container body A when the lid is closed to create a sealed state, and a lower sealing tube 22b is provided on the lower outer periphery of the sealing tube 22, with a step portion 22a provided on the outer periphery, which is reduced in diameter, and the lower end of the outer periphery of the lower sealing tube 22b is formed so that it is close to or in contact with the upper end of the inner periphery 2a of the spout portion 2 when the lid is closed, and another temporary sealing portion Sb is formed below the sealing portion Sa by the lower end of the outer periphery of the lower sealing tube 22b and the upper end of the inner periphery 2a. The pouring container is sealed with two seals, the seal part Sa and the temporary seal part Sb, so that even if one seal is removed due to an impact, the other seal will seal and the content liquid will not leak. In addition, a space is formed between the step 22a of the sealing tube 22 and the step 2b of the outlet portion 2, which serves as a liquid reservoir Sc to retain the contents when a small amount of liquid enters the temporary seal portion Sb due to an impact such as when the container is dropped.

[0023] Next, the manner of use and the effects of this embodiment will be described. The hinged cap B of this embodiment is made of synthetic resin (such as PE or PP) that has a certain degree of flexibility, and is manufactured by integral molding in the open state as shown in FIG. The container body A is a PET bottle blow-molded from PET resin, with at least the nozzle 1 being hard.

[0024] The cap body B1 of the open hinged cap B is placed from above the insertion opening 6 of the container body A, the vertical engagement piece 16 of the cap body B1 is inserted into the top opening 9 of the insertion opening 6, and the locking protrusion 17 is made to climb over the inner surface of the engagement wall portion 8 of the insertion opening 6, and the cap body B1 is fitted into the insertion opening 6 of the container body A and attached. At this time, the vertical engagement piece 16 and the upper surface of the upper opening 9 coincide with each other, and the locking protrusion 17 engages with the lower edge of the inner surface of the engagement wall portion 8, preventing the cap body B1 from coming off the container body A or moving within the insertion opening portion 6. After attachment, the upper and outer surfaces of the outer wall portion 4 of the container body A and the upper and outer surfaces of the attachment base portion 15 of the cap body B1 become flush with each other, improving the appearance.

[0025] In the hinged cap B of this embodiment, the cap body B1 is attached to the mouth portion 1 of the container body A over only a partial range of the mouth portion 1 of the container body A (an angle range θ of approximately 90° when viewed from above), so it can be molded using a smaller amount of resin than conventional cylindrical cap bodies that engage with the entire mouth portion of the container body.

[0026] In this embodiment, when viewed from above, the insertion opening 6 of the cap body B1 and the container body A is formed with an angle range θ of approximately 90°, but if the width of the hinge B2 is small, the angle range θ of the cap body B1 and the insertion opening 6 of the container body A may be formed with an angle range of less than 90° to match, or the angle range θ may be formed within a range of up to 180° on the hinge B2 side. As long as the cap body B1 can be attached to the insertion opening 6, any angle range θ is acceptable as long as the angle ranges θ are similar to each other, and the angle range θ is not limited to the angle range in the above embodiment. Furthermore, a smaller angle range θ allows for molding with a smaller amount of resin.

[0027] After fitting the cap body B1 into the insertion opening 6 of the container body A, the top lid B3 is rotated around the hinge B2 as a fulcrum, so that the outer periphery of the sealing tube 22 of the top lid B3 is tightly fitted to the inner periphery of the pouring outlet 2 of the container body A, and the locking recess 23 of the side wall 21 of the top lid B3 is engaged with the lid locking protrusion 7 of the lid engagement portion 5 of the container body A, thereby making the top lid B3 a closed pouring container.

[0028] When the lid is closed, the lower outer periphery of the sealing tube 22 of the upper lid B3 comes into close contact with the upper part of the expanded inner periphery 2c of the spout portion 2 of the container body A, forming a sealing portion Sa, and the lower end of the lower sealing tube 22b at the lower end of the sealing tube 22 comes close to or abuts against the upper end of the inner periphery 2a of the spout portion 2, forming a temporary sealing portion Sb.

[0029] When the pouring container of this embodiment is in a closed state, it is sealed in two stages: a seal portion Sa between the lower outer periphery of the sealing tube 22 of the upper lid B3 and the inner periphery of the expanded inner periphery 2c of the pouring outlet portion 2 of the container body A, and a temporary seal portion Sb between the lower sealing tube 22b and the inner periphery 2a of the pouring outlet portion 2. Even if one seal comes off due to an impact, the other seal will be established, maintaining the airtightness of the container body A. Furthermore, even if the contents enter the temporary seal portion Sb due to an impact such as when dropped, the liquid reservoir portion Sc will retain the contents and prevent them from leaking from the seal portion Sa.

[0030] To use the liquid contents in the container body A, the user places his or her fingers on the finger grip portion 24 of the top lid B3 and lifts it, causing the top lid B3 to rotate around the hinge B2, and first the temporary seal portion Sb of the lower seal tube 22b of the seal tube 22 of the top lid B3 with the inner surface 2a of the outlet portion 2 is released, and then the seal portion Sa of the seal tube 22 with the outlet portion 2 of the container body A is released, and the top lid B3 is opened.By simply tilting the container body A, the liquid contents in the container body A can be easily guided through the outlet portion 2 and poured out from the front side of the nozzle portion 3.

[0031] By closing the upper lid B3 again on the container body A, the lower sealing tube 22b of the sealing tube 22 of the upper lid B3 comes close to the inner surface 2a of the spout portion 2 to form a temporary sealing portion Sb, and the outer periphery of the sealing tube 22 comes into close contact with the inner periphery of the spout portion 2 of the container body A to form a sealing portion Sa, thereby sealing the inside of the container body A and allowing the spouting container to be used by repeatedly opening and closing the upper lid B3.

[0032] In the dispensing container of this embodiment, the vertical engagement piece 16 and the top opening 9 are formed in a C-shape when viewed from above, and fit together, and the locking protrusion 17 engages with the lower edge of the inner surface of the engagement wall portion 8, so that the cap body B1 will not come off from the container body A due to the rotational or lateral force generated when the top lid B3 is opened or closed relative to the container body A.

[0033] Next, when the liquid contents filled in the container body A have been used up and the dispensing container is to be discarded, the top lid B3 is opened and pulled upward, and the cap body B1 is lifted as vertically as possible relative to the container body A. Since the vertical engagement piece 16 and the top opening 9 are only inserted vertically, it can be removed with little resistance. All that remains is to move the locking protrusion 17 over the engagement wall portion 8, and the hinged cap B can be easily removed from the container body A and separated. [Example]

[0034] Next, a second embodiment in which the configurations of the insertion opening 6 of the container body A and the cap body B1 of the hinged cap B of the first embodiment are changed will be described with reference to FIGS. In the following, the same components as those in the first embodiment are given the same reference numerals, and new reference numerals are given to changed components, and the explanation will focus on the differences.

[0035] In Figures 5 and 6, Aa denotes the container body, and Ba denotes the hinged cap. As shown in Figures 5 to 7, the outer periphery of the mouth portion 1 of the container body Aa is formed with an outer wall portion 30 on the lower back side to which a hinged cap Ba is attached, and a lid engagement portion 31 on the upper front side of the outer wall portion 30 that engages with the hinged cap Ba to keep the lid closed. As shown in Figure 7, the back side of the outer peripheral wall portion 30 is cut into a C-shape when viewed from above at a width da1 from the outer periphery of the outer peripheral wall portion 30 within a predetermined angle range θ (approximately 90° from the back side) and a predetermined height range ha1 of the outer peripheral wall portion 30, forming an insertion opening portion 32 for attaching the cap body Ba1 of the hinged cap Ba described below. On the back side of the lid engagement portion 31, an upper recess 33 is formed which is cut in a C-shape when viewed from above, with a width da2 from a position shallower than the depth of the insertion opening 32 toward the inner periphery to the outer periphery of the lid engagement portion 31, and which has the same angular range θ as the insertion opening 32, and from the upper end of the lid engagement portion 31 to the upper end of the outer periphery wall portion 30.

[0036] The upper recess 33 forms side end faces 33a on both sides and a rear side face 33b, and between the side end faces 33a on both sides of the lid engagement portion 31, an engagement wall portion 34 is provided on the outer periphery at a height within a height range ha2 from the lower end, which is C-shaped when viewed from above and connects the two sides. When viewed from above, the inner surface of the engagement wall portion 34 is spaced a predetermined width da3 from the rear side surface 33b, with a C-shaped upper surface opening 35 formed in between, and the outer surface is formed so as to be flush with the outer surface of the lid engagement portion 31, and the lower surface is at the same height as the upper surface of the outer peripheral wall portion 30.

[0037] The insertion opening 32 is formed on the inner periphery deeper than the rear side surface 33b of the upper recess 33 by a predetermined width da4, and has side end surfaces 32a and a bottom surface 32b on both sides, and a top surface 32c which forms the underside of part of the rear side of the lid engagement portion 31. Furthermore, a side opening 36 is formed between the lower surface of the engagement wall 34 and both side end surfaces 32a and the bottom surface 32b.

[0038] As shown in Figures 5, 6 and 8, the hinged cap Ba comprises a cap body Ba1 that is attached to the insertion port portion 32 of the container body Aa, and an upper lid B3 that is connected to the cap body Ba1 via a hinge B2 and opens and closes the pouring outlet portion 2.

[0039] The cap body Ba1 is formed in a shape (a C-shape with an angle range θ of approximately 90° centered on the back side) that fits laterally into the insertion opening 32 of the container body Aa when viewed from above, and consists of an attachment base 40 to which a hinge B2 is connected at the upper end of its outer periphery, a lateral engagement piece 41 that extends inward from the inner periphery of the attachment base 40 and fits into the side opening 36, and a locking protrusion 42 that protrudes from a position approximately a width da4 away from the inner periphery of the upper surface of the lateral engagement piece 41 and engages with the lower edge of the top opening 35.

[0040] The mounting base 40 and the lateral engagement piece 41 are formed at a height within a height range ha1 from the upper end, and when mounted, the lower and side surfaces engage with the bottom surface 32b and both side end surfaces 32a of the insertion opening 32, the front side of the engagement protrusion 42 of the lateral engagement piece 41 engages with the top surface 32c, and the area near the back side of the engagement protrusion 42 of the lateral engagement piece 41 engages with the lower surface of the engagement wall portion 34 of the upper recess 33.

[0041] Next, the manner of use and the effects of this embodiment will be described. The front side of the cap body Ba1 of the open hinged cap Ba is placed against the back side of the insertion opening 32 of the container body Aa, the horizontal engagement piece 41 of the cap body Ba1 is inserted from the side into the side opening 36 of the insertion opening 32, and the locking protrusion 42 of the cap body Ba1 is moved over the lower end of the engagement wall 34, and the cap body Ba1 is fitted into the insertion opening 32 of the container body Aa and attached. At this time, the locking protrusion 42 and the lower edge of the upper opening 35 of the upper recess 33 engage with each other, preventing the cap body Ba1 from coming off the container body Aa or moving within the insertion opening 32. After attachment, the upper and outer surfaces of the outer peripheral wall portion 30 of the container body Aa and the upper and outer surfaces of the attachment base portion 40 of the cap body Ba1 become flush with each other, improving the appearance.

[0042] In the hinged cap Ba of this embodiment, the cap body Ba1 that is attached to the mouth portion 1 of the container body Aa is attached at an angle range θ, so it can be molded using a smaller amount of resin than conventional cylindrical cap bodies.

[0043] In the dispensing container of this embodiment, the mounting base 40 and horizontal engagement piece 41 of the cap body Ba1 and the insertion opening 32 and engagement wall 34 of the upper recess 33 of the container body Aa are formed in a C-shape when viewed from above, and they fit together at their surfaces, and the locking protrusion 42 engages with the inner edge of the lower end of the upper opening 35, so that the cap body Ba1 will not come off the container body Aa due to the rotational or vertical force applied when the upper lid B3 is opened or closed relative to the container body Aa.

[0044] When disposing of the dispensing container, the top lid B3 is opened and pulled sideways, and the cap body Ba1 is pulled sideways relative to the container body Aa. The horizontal engagement piece 41 and the side opening 36 are simply inserted sideways, so the cap can be removed with little resistance. All that remains is to move the locking protrusion 42 over the lower end of the engagement wall 34, and the hinged cap Ba can be easily removed from the container body Aa and separated. Other functions and effects are the same as those of the first embodiment. [Example]

[0045] Next, a third embodiment in which the configuration of the spout portion 2 of the container body A and the hinged cap B of the first embodiment is modified will be described with reference to FIG. In the following, the same components as those in the first embodiment are given the same reference numerals, and new reference numerals are given to changed components, and the explanation will focus on the differences.

[0046] In FIG. 9, Ab denotes a container body, and Bb denotes a hinged cap that is attached to the mouth 1 of the container body Ab and closes the mouth 1.

[0047] The container body Ab has a cylindrical mouth portion 1 whose upper end is formed horizontally, and the inner periphery of the mouth portion 1 forms a spout portion 50. The spout portion 50 is formed with an inner circumferential surface 50a that continues from below, an expanded inner circumferential surface 50c that expands in diameter from the upper inner circumferential surface 50a via a step portion 50b, and a pouring surface 50d that extends outward from the upper end of the expanded inner circumferential surface 50c at the upper end. The upper end of the nozzle portion 1 is a horizontally formed nozzle portion 51 that itself continues from the pouring surface 50d, and on the front side in the pouring direction, a lip portion 51a is formed that continues from the pouring surface 50d and has a flared tip.

[0048] The hinged cap Bb comprises a cap body B1 that is attached to the insertion opening 6 of the container body Ab, and an upper cover Bb3 that is connected to the cap body B1 via a hinge B2 and that opens and closes the spout 2.

[0049] The top cover Bb3 comprises a top wall 20, a side peripheral wall 21 that hangs down from the peripheral edge of the top wall 20 and has a hinge B2 connected to the back side of the lower outer periphery, and a sealing tube 55 that hangs down from the underside of the top wall 20.

[0050] The sealing tube 55 has a normal sealing portion Sa, whose lower outer end is inserted into the upper part of the expanded inner surface 50c of the spout portion 50 of the container body Ab when the lid is closed, to create a sealed state, and a lower sealing tube 55b is provided on the lower outer periphery of the sealing tube 55, which has a reduced diameter and a step portion 55a, and the lower sealing tube 55b is formed so that its lower outer end is close to or abuts the upper end of the inner surface 50a of the spout portion 50 when the lid is closed, and another temporary sealing portion Sb is formed below the sealing portion Sa by the lower outer periphery end of the lower sealing tube 55b and the upper end of the inner surface 50a. The cap is sealed with two seals, the seal portion Sa and the temporary seal portion Sb, so even if one seal comes off due to an impact, the other seal will seal and no liquid will leak. In addition, a space is provided between the step 55a of the sealing tube 55 and the step 50b of the outlet portion 50, which serves as a liquid reservoir Sc to retain the contents when a small amount of contents enters the temporary seal portion Sb due to an impact such as when the container is dropped.

[0051] Next, the effects of this embodiment will be described. When the lid is closed, the lower outer circumferential end of the sealing tube 55 of the upper lid Bb3 comes into close contact with the upper end of the expanded inner circumferential surface 50c of the spout portion 50 of the container body Ab, forming a sealing portion Sa, and the lower outer circumferential end of the lower sealing tube 55b at the lower end of the sealing tube 55 comes close to or abuts against the upper end of the inner circumferential surface 50a of the spout portion 50, forming a temporary sealing portion Sb.

[0052] When the pouring container of this embodiment is in a closed state, it is sealed in two stages: a seal portion Sa between the lower outer periphery of the sealing tube 55 of the upper lid Bb3 and the upper end of the enlarged inner periphery 50c of the pouring outlet portion 50 of the container body Ab, and a temporary seal portion Sb between the lower end of the lower sealing tube 55b and the upper end of the inner periphery 50a of the pouring outlet portion 50. Even if one seal comes off due to an impact, the other seal will be formed, maintaining the airtightness of the container body Ab. Furthermore, even if the contents enter the temporary seal portion Sb due to an impact such as when dropped, the liquid reservoir portion Sc will retain the contents and prevent them from leaking from the seal portion Sa.

[0053] To use the liquid contents in the container body Ab, one places one's fingers on the finger grip portion 24 of the top lid Bb3 and lifts it, causing the top lid Bb3 to rotate around the hinge B2, and first the lower sealing tube 55b of the sealing tube 55 of the top lid Bb3 releases the temporary seal portion Sb with the inner surface 50a of the spout portion 50, and then the sealing tube 55 releases the seal portion Sa with the spout portion 50 of the container body Ab, and the top lid Bb3 is opened.By simply tilting the container body Ab toward the front, the liquid contents in the container body Ab can be guided through the inner surface 50a, step portion 50b, enlarged inner surface 50c, and pouring surface 50d of the spout portion 50, and can be poured out from the lip portion 51a on the front side. Other functions and effects are the same as those of the first embodiment. [Industrial Applicability]

[0054] The dispensing container of the present invention has a hinged cap whose cap body is attached to the mouth of the container body only on the hinge side, so that the hinged cap can be molded using a smaller amount of resin than conventional ones, and can be widely used as a variety of dispensing containers.
