Description

[Technical Field]

[0001] The present invention relates to a cap and a container equipped with a cap. [Background technology]

[0002] Conventionally, an example of this type of cap is a hinge cap 200 that is attached to the mouth of a container, as shown in Figures 14 and 15. The hinge cap 200 has a cap body 201 that is attached to the mouth, a lid 202 that opens and closes a spout formed in the cap body 201, and a hinge that connects the cap body 201 and the lid 202.

[0003] The cap body 201 is provided with a plate member 203 that prevents the lid 202 from being opened. The plate member 203 is attached to the mating surface (upper surface) of the outer cylinder 205 of the cap body 201 via a breakable portion 204.

[0004] A plurality of openings 206 are formed in the plate member 203, and a plurality of protrusions 207 are formed in the lid 202. As shown in Figure 14, when the lid 202 is closed, the protrusions 207 get caught in the openings 206, preventing the lid 202 from being opened.

[0005] Additionally, on the outer peripheral surface of lid 202, there are formed recess 208 recessed radially inward, and finger hook 209 for pushing open lid 202 with fingers when opening the bottle. Finger hook 209 is a flange that projects outward from recess 208, and is located above protrusion 207.

[0006] 14, when the hinge cap 200 is unopened, the presence of the plate member 203 allows visual confirmation of the unopened state. At this time, the protrusion 207 is caught in the opening 206, preventing the lid 202 from opening accidentally.

[0007] When opening the hinge cap 200, as shown in FIG. 15, the intended breaking portion 204 is cut off to separate the plate member 203, and then the finger hook portion 209 is pushed up from below with the thumb 210, for example, to open the lid 202. The hinge cap 200 as described above is described in, for example, Patent Document 1 below. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Patent No. 5797584 Summary of the Invention [Problem to be solved by the invention]

[0009] However, in the above-described conventional type, the formation of protrusion 207 and finger hook 209 on lid 202 complicates the structure and may increase manufacturing costs. Also, when thumb 210 is used to push finger hook 209 from the bottom up to open lid 202, protrusion 207 may interfere with the action of thumb 210 pushing finger hook 209 up, making it difficult to push finger hook 209 up with thumb 210. The present invention aims to provide a cap and a container that can be opened by smoothly pushing the lid open with fingers and that can reduce manufacturing costs. [Means for solving the problem]

[0010] In order to achieve the above object, the first invention provides a cap having a cap body attached to a container, a lid for opening and closing a spout formed in the cap body, and a hinge for connecting the cap body and the lid, A sealing band that prevents the lid from being opened is attached to the cap body via a breakable weakened portion, A first distance from the axial center of the cap to the outer peripheral surface of the sealing strip is equal to or less than a second distance from the axial center of the cap to the outer peripheral surface of the cap body, The sealing strip is provided with a first engagement portion, The lid is provided with a second engagement portion that can engage with the first engagement portion in the opening direction when the lid is opened, The second engagement portion protrudes radially outward from the outer peripheral surface of the lid, and also serves as a finger hook for pushing open the lid with fingers when opening the bottle.

[0011] According to this, when the cap is unopened, the sealing strip is attached to the cap body via the weakened portion, so that the unopened state can be visually recognized. In this case, since the first distance is equal to or less than the second distance, the sealing strip does not protrude radially outward from the outer peripheral surface of the cap body, and the appearance of the cap is improved. When the cap is in an unopened state, the second engagement portion engages with the first engagement portion, thereby preventing the lid from opening accidentally.

[0012] When opening an unopened cap, the seal strip is removed from the cap body by applying an external force to the seal strip, causing the weakened portion to break.Then, the lid can be opened by pushing up the second engagement portion with a finger.

[0013] In this case, since the second engagement portion also serves as a finger hook, there is no need to provide a finger hook (such as a flange) on the lid in addition to the second engagement portion, which allows for reduced manufacturing costs.

[0014] Furthermore, if a finger hook (e.g., a flange) is provided separately from the second engagement portion, when pushing up the finger hook with a finger, the second engagement portion may interfere with the pushing-up action, making it difficult to push up the finger hook with a finger. In contrast, in the first invention, the second engagement portion also serves as the finger hook, so there is no risk of the second engagement portion interfering with the pushing-up action, and the lid can be pushed open smoothly with a finger when opening the bottle.

[0015] In the cap according to the second aspect of the present invention, the second distance is equal to a third distance from the axis of the cap to the outer peripheral surface of the lid. This improves the appearance of the cap when it is unopened.

[0016] In the cap according to the third aspect of the present invention, the outer peripheral surface of the lid has a first recess recessed inward in the radial direction, The second engagement portion is provided in the first recess, The seal strip is disposed within the first recess when unopened, The first distance is equal to or less than a third distance from the axis of the cap to the outer peripheral surface of the lid. This improves the appearance of the cap when it is unopened.

[0017] The cap in the fourth aspect of the present invention has a second recess formed on the outer circumferential surface of the cap body, where a finger is placed when opening the cap, the second recess is recessed radially inward from the outer circumferential surface of the cap body and is located directly below the second engagement portion when the cap is closed; a fourth distance from the axis of the cap to the second recess is shorter than the second distance; A fifth distance from the axis of the cap to the first recess is equal to or less than the fourth distance.

[0018] According to this, after removing the sealing strip from the cap body, a finger is placed on the second recess of the cap body and the second engagement portion is pushed up with the finger. At this time, because the fifth distance is equal to or less than the fourth distance, the first recess of the lid does not protrude radially outward from the second recess of the cap body, so that the action of pushing up the second engagement portion with the finger can be performed smoothly.

[0019] In the cap of the fifth invention, the first engaging portion is a through hole that penetrates the inner peripheral surface and the outer peripheral surface of the sealing strip, The penetration hole is surrounded by a seal band, When the package is unopened, the second engagement portion fits into the through hole from the inner periphery side of the sealing strip.

[0020] According to this, in an unopened cap, the second engagement portion fits into the through opening from the inner peripheral side of the sealing band, making it difficult to push the second engagement portion into the inside of the sealing band from the outside. Therefore, it is difficult to push the second engagement portion into the inside of the sealing band from the outside and remove it from the through opening. This makes it possible to prevent fraudulent acts such as opening the lid of an unopened cap while the sealing band is still attached to the cap body.

[0021] The cap according to the sixth aspect of the present invention is a container equipped with the cap according to the first aspect of the present invention, A bag-shaped container body and a spout provided on the container body, The cap body is attached to the spout. [Effects of the Invention]

[0022] As described above, according to the present invention, the second engagement portion also serves as a finger hook, so there is no need to provide a finger hook (such as a flange) on the lid in addition to the second engagement portion, thereby reducing manufacturing costs.

[0023] Furthermore, if a finger hook (for example, a flange) is provided in addition to the second engagement portion, when pushing up the finger hook with a finger, the second engagement portion may interfere with the pushing-up action, making it difficult to push up the finger hook with a finger. In contrast, in the present invention, the second engagement portion also serves as the finger hook, so there is no risk of the second engagement portion interfering with the pushing-up action, and the lid can be pushed open smoothly with a finger when opening the bottle.

[0025] Hereinafter, embodiments of the present invention will be described with reference to the drawings. (First embodiment)

[0026] In the first embodiment, as shown in Fig. 1, reference numeral 1 denotes a container equipped with a cap 2. The container 1 has a bag-shaped container body 3 and a spout 4 provided on the top of the container body 3. The container body 3 may be, for example, a pouch.

[0027] The spout 4 has a welding part 5 for connection to the container body 3, and a cylindrical discharge part 6 erected on the welding part 5. A male thread 7 and a flange 8 are provided on the outer periphery of the discharge part 6.

[0028] As shown in Figures 1 to 5, the cap 2 has a cap body 11 attached to the discharge portion 6 of the spout 4, a lid 13 that opens and closes the spout 12 formed in the cap body 11, and a hinge 14 that connects the cap body 11 and the lid 13.

[0029] Here, the direction of the axis 16 (hereinafter referred to as the cap axis 16) passing through the center of the cap 2 is the vertical direction 17, the direction perpendicular to the cap axis 16 is the radial direction 18, and the circumferential direction centered on the cap axis 16 is the circumferential direction 19.

[0030] The cap body 11 has a partition wall 21 attached to close the tip opening of the discharge part 6 of the spout 4, an injection nozzle 22 protruding upward from the partition wall 21, an outer tube 23 extending downward from the outer peripheral edge of the partition wall 21, an inner tube 24 positioned inside the outer tube 23 and extending downward from the partition wall 21, and a groove 25 formed around the entire circumference between the outer tube 23 and the inner tube 24. The outer cylinder 23 has an inner periphery formed with a plurality of engagement recesses (not shown) that engage with the male threads 7 of the spout 4 .

[0031] 1, when the tip of discharge part 6 of spout 4 is inserted into groove 25, inner tube 24 fits onto the inner periphery of the tip of discharge part 6, and outer tube 23 fits onto the outer periphery of the tip of discharge part 6, so that male thread 7 of spout 4 fits into a mating recess in outer tube 23. In this way, cap body 11 is attached to discharge part 6 of spout 4.

[0032] The spout 12 is formed at the tip of the spout nozzle 22. An annular closure member 27 is provided on the upper surface of the partition wall 21. A closure recess 28 recessed inward in the radial direction 18 is formed around the entire periphery of the closure member 27.

[0033] The dispensing nozzle 22 is disposed radially inward in the radial direction 18 relative to the closing member 27. As shown in Figures 4 and 5, an axis 30 passing through the center of the dispensing nozzle 22 (hereinafter referred to as the dispensing nozzle axis 30) is eccentric to the cap axis 16 by 180° opposite to the hinge 14.

[0034] The lid 13 has a circular top plate 35, a cylindrical lid outer wall 35 provided on the outer peripheral edge of the top plate 35, and a cylindrical sealing member 36 provided on the top plate 35 and arranged inside the lid outer wall 35. The inner peripheral surface of the lid outer wall 35 is provided with a closing protrusion 37 that protrudes inward in the radial direction 18.

[0035] As shown in Figure 1, when the lid 13 is closed and in the closed state, the sealing member 36 is inserted into the dispensing nozzle 22, the dispensing outlet 12 is closed by the lid 13, and the outer surface of the sealing member 36 is in close contact with the inner surface of the dispensing nozzle 22 all around, thereby sealing the gap between the dispensing nozzle 22 and the lid 13 and the closing protrusion 37 fitting into the closing recess 28.

[0036] A sealing band 38 that prevents the lid 13 from being opened is provided on the partition wall 21 of the cap body 11 via a plurality of breakable weakened portions 39. The sealing band 38 is curved in an arc shape in a plan view. The sealing band 38 has a through hole 41 (an example of a first engagement portion) that penetrates from the inner peripheral surface to the outer peripheral surface and is elongated in the circumferential direction 19. As a result, the through hole 41 is surrounded by the sealing band 38. The weakened portion 39 is a thin bridge connecting the lower end of the sealing strip 38 to the upper surface of the bulkhead 21 .

[0037] 2, 3 and 5 to 7, the outer peripheral surface of the lid outer wall 35 has a first recess 45 recessed inward in the radial direction 18. The first recess 45 of the lid 13 is provided with a second engagement portion 48 that can engage with the through-hole 41 in the opening direction 46 when the lid is opened.

[0038] The second engagement portion 48 protrudes outward in the radial direction 18 from the outer peripheral surface of the first recess 45 (corresponding to the outer peripheral surface of the lid 13), and also serves as a finger hook (for example, a flange) for pushing open the lid 13 with a finger when opening the bottle. As shown in Figures 1 to 3, when the bottle is unopened, the second engagement portion 48 fits into the through opening 41 from the inner peripheral side of the sealing band 38.

[0039] 1 to 3, when the cap 2 is unopened, the sealing strip 38 is disposed in the first recess 45. A second recess 50 is formed on the outer peripheral surface of the outer tube 23 of the cap body 11, where a finger is placed when opening the cap. The second recess 50 is recessed inward in the radial direction 18 from the outer peripheral surface of the outer tube 23, and is located directly below the second engagement portion 48 when the cap is closed. The sealing strip 38 , the first recess 45 , the second recess 50 , the through hole 41 and the second engagement portion 48 are provided on the side of the cap axis 16 farther away from the hinge 14 .

[0040] As shown in Figures 3 and 4, a first radius R1 (an example of a first distance) from the cap axis 16 to the outer peripheral surface of the sealing band 38 is the same as a second radius R2 (an example of a second distance) from the cap axis 16 to the outer peripheral surface of the outer tube 23 of the cap body 11.

[0041] 3 and 4, the second radius R2 is the same as a third radius R3 (an example of a third distance) from the cap axis 16 to the outer peripheral surface of the lid outer wall 35 of the lid 13. In addition, the first radius R1 is the same as the third radius R3.

[0042] 4 and 7, a fourth radius R4 (an example of a fourth distance) from the cap axis 16 to the second recess 50 is shorter than the second radius R2. A fifth radius R5 (an example of a fifth distance) from the cap axis 16 to the first recess 45 is the same as the fourth radius R4. The operation of the above configuration will be described.

[0043] 1 to 3, when the cap 2 is unopened, the unopened state can be visually recognized because the sealing strip 38 is attached to the cap body 11 via the weakened portion 39. In this case, because the first radius R1 and the second radius R2 are the same, the sealing strip 38 does not protrude outward in the radial direction 18 from the outer peripheral surface of the outer tube 23 of the cap body 11, improving the appearance of the cap 2.

[0044] When the cap 2 is in an unopened state, the second engagement portion 48 of the lid 13 engages with the through hole 41 of the sealing strip 38, thereby preventing the lid 13 from opening accidentally.

[0045] 1, in the unopened cap 2, the second engagement portion 48 is fitted into the through opening 41 from the inner circumferential side of the sealing strip 38, and therefore the peripheral edge of the through opening 41 gets in the way, making it difficult to push the second engagement portion 48 from the outside to the inside of the sealing strip 38. Therefore, it is difficult to push the second engagement portion 48 from the outside to the inside of the sealing strip 38 to remove it from the through opening 41.

[0046] This makes it possible to prevent fraudulent acts such as opening (unsealing) the lid 13 of an unopened cap 2 with the sealing strip 38 still attached to the cap body 11.

[0047] Furthermore, as shown in Figure 4, the first radius R1 and the third radius R3 are the same, and further, the second radius R2 and the third radius R3 are the same, so that, as shown in Figure 2, the outer surface of the sealing band 38 and the outer surface of the lid outer wall 35 are on the same plane, and the outer surface of the outer tube 23 and the outer surface of the lid outer wall 35 are on the same plane, which gives the cap 2 a good appearance when unopened.

[0048] When opening the unopened cap 2, the sealing band 38 is applied with force, for example by pinching the sealing band 38 with the fingers, to break the weakened portion 39, thereby removing the sealing band 38 from the cap body 11 as shown by the imaginary line in Fig. 3 and in Fig. 6. Thereafter, as shown in Fig. 7, for example, by placing a thumb 53 on the second recess 50 of the cap body 11 and pushing up the second engagement portion 48 from below with the thumb 53, the lid 13 can be opened as shown in Fig. 8.

[0049] In this case, since the second engagement portion 48 also serves as a finger hook, there is no need to provide the lid 13 with a finger hook (for example, a flange or the like) in addition to the second engagement portion 48. This makes it possible to reduce manufacturing costs.

[0050] 4 and 7, since the fourth radius R4 and the fifth radius R5 are the same, when the second engagement portion 48 is pushed up with the thumb 53 as described above, the outer peripheral surface of the first recess 45 and the outer peripheral surface of the second recess 50 are smoothly continuous without any steps. This allows the thumb 53 to smoothly push up the second engagement portion 48.

[0051] The cap 2 is manufactured by injection molding using a mold 55 as shown in Fig. 9. The mold 55 has a lower mold 56 that forms the outer side of the lid 13 that opens downward from the partition wall 21 of the cap body 11 and at an angle of 180°, an upper mold 57 that forms the inner side of the lid 13 that opens upward from the partition wall 21 of the cap body 11 and at an angle of 180°, and a slide core 58 provided between the lower mold 56 and the upper mold 57. A parting line 60 (seam) of the mold 55 is located at the location where the second engaging portion 48 of the cap 2 is formed.

[0052] Each of the lower mold 56 and the upper mold 57 has a plurality of cores 59a to 59n that are movable in the vertical direction 17. The slide core 58 forms the sealing band 38, the weakened portion 39, the through hole 41, and the second recess 50 shown in FIG. 4, and is movable in the horizontal direction 61 that is perpendicular to the vertical direction 17.

[0053] According to this method, the molded product space inside the mold 55 is filled with molten synthetic resin material 62, then the filled synthetic resin material 62 is cooled and solidified, and then the cooled and solidified synthetic resin material 62 is released from the mold 55.

[0054] At this time, the synthetic resin material 62 is released from the mold 55 by moving each of the cores 59a to 59n in the vertical direction 17 in a predetermined order and moving the slide core 58 in the horizontal direction 61. In this way, the mold 55 requires only one slide core 58, so that the manufacturing cost when injection molding the cap 2 can be reduced. (Comparative Example)

[0055] A comparative example to the first embodiment will be described with reference to Figures 10 to 13. Note that the same components as those described in the first embodiment will be denoted by the same reference numerals, and detailed description thereof will be omitted.

[0056] 10 and 11, a sealing strip 102 that prevents the lid 13 from being opened is provided on the partition wall 21 of the cap 101 in the comparative example via a plurality of breakable weakened portions 103. Engagement recesses 104 (first engagement portions) are formed at two locations in the circumferential direction 19 of the sealing strip 102. These engagement recesses 104 penetrate the outer and inner peripheral surfaces of the sealing strip 102 and are open downward. The first recess 45 of the lid 13 is provided with a plurality of second engagement portions 105 that can engage with the engagement recesses 104 in the opening direction 46 when the cap is opened.

[0057] The second engagement portions 105 are provided at two locations in the circumferential direction 19 of the lid 13, and as shown in Fig. 12, protrude outward in the radial direction 18 from the outer peripheral surface of the first recess 45 (corresponding to the outer peripheral surface of the lid 13). As shown in Figs. 10 and 11, when the package is unopened, the second engagement portions 105 engage with the engagement recess 104 from the inner peripheral side of the sealing strip 102.

[0058] A finger hook 106 is provided on the outer peripheral edge of the top plate 34 of the lid 13 and at the upper end of the first recess 45 to push open the lid 13 with a finger when opening the container. The finger hook 106 is a flange that protrudes outward in the radial direction 18 from the first recess 45.

[0059] As shown in FIGS. 10 and 11, when the cap 101 is unopened, the sealing strip 102 is placed in the first recess 45 of the lid 13 and the finger hook 106 is located above the second engagement portion 105.

[0060] According to this, when the cap 101 is unopened, the second engaging portion 105 engages with the engaging recess 104, thereby preventing the lid 13 from opening accidentally.

[0061] When opening the unopened cap 101, an external force is applied to the sealing strip 102, for example by pinching the sealing strip 102 with fingers, thereby breaking the weakened portion 103 and removing the sealing strip 102 from the cap body 11 as shown by the imaginary line in Fig. 11. Thereafter, as shown in Fig. 12, the lid 13 can be opened by pushing up the finger hook portion 106 from below with, for example, the thumb 53. At this time, since the second engagement portion 105 is located below the finger hook portion 106, there is a risk that it may interfere with the action of pushing up the finger hook portion 106 with the thumb 53.

[0062] The cap 101 as described above is manufactured by injection molding using a mold 110 as shown in Fig. 13. The mold 110 has a lower mold 56, an upper mold 57, and first and second slide cores 58, 111 provided between the lower mold 56 and the upper mold 57.

[0063] Of these, the first slide core 58 forms the sealing band 102 , the weakened portion 103 and the engaging recess 104 , and is movable in the lateral direction 61 perpendicular to the vertical direction 17 . The second slide core 111 forms the first recess 45 of the lid 13, the second engagement portion 105, and the finger hook portion .

[0064] According to this, in the cap 101 given as a comparative example, the second engagement portion 105 and the finger hook portion 106 are each provided separately on the lid 13 as shown in Fig. 12, and therefore a second slide core 111 is required in addition to the first slide core 58 as shown in Fig. 13. In this way, in the comparative example, two slide cores 58, 111 need to be provided in the mold 110, and therefore the manufacturing cost when injection molding the cap 101 may be higher than that of the first embodiment described above.

[0065] In contrast, in the cap 2 of the first embodiment described above, as shown in FIG. 7, the second engagement portion 48 also serves as a finger hook portion, so that only one slide core 58 is required in the mold 55, as shown in FIG. 9, thereby reducing manufacturing costs.

[0066] In the first embodiment, as shown in FIGS. 3 and 4, the first radius R1 (an example of the first distance) is the same as the second radius R2 (an example of the second distance), but may be slightly shorter than the second radius R2. Furthermore, the first radius R1 is the same as the third radius R3 (an example of the third distance), but may be slightly shorter than the third radius R3. Furthermore, as shown in FIGS. 4 and 7, the fifth radius R5 (an example of the fifth distance) is the same as the fourth radius R4 (an example of the fourth distance), but may be slightly shorter than the fourth radius R4.

[0067] In the first embodiment, as shown in Fig. 1, the cap 2 is attached to a spout 4 of a container body 3 such as a pouch, but it may also be attached to the opening of a container body such as a PET bottle. In this case, a cap body 11 is attached to the opening. In the first embodiment, as shown in FIG. 7, the lid 13 is opened using the thumb 53, but a finger other than the thumb 53 may also be used.
