Description

[Technical field]

[0001] The present invention relates to a dispensing cap, and more particularly to a dispensing cap that is attached to a squeeze container body. [Background technology]

[0002] Conventionally, in pouring caps attached to so-called squeeze containers, the contents are poured out by squeezing the body of the container with the hand and the container returns to its original state when the hand is released. In such cases, when the container body is tilted from an upright position to an inclined position, the contents sometimes drip out of the pouring outlet.

[0003] For this reason, a dispensing cap is known that is provided with a discharge valve that opens and closes the communication hole in response to fluctuations in the internal pressure of the container body when the container body is squeezed, switching the communication hole between open and closed (see Patent Document 1), so that the contents do not immediately drip when the container body is simply tilted from an upright position. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2020-33087 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the dispensing cap described in Patent Document 1 above, the discharge hole (dispensing outlet) is positioned offset from the bottle axis toward the opposite side to the hinge, relative to the discharge valve which is coaxial with the bottle axis. Therefore, when the container body is squeezed hard to dispense a large amount of contents, the contents flow in uneven directions from the discharge valve along the inner circumference of the inner stopper to the underside of the top wall, causing disruption in the flow of the contents and causing them to splash around from the discharge hole.

[0006] The present invention has an object to solve the above problems and to provide a pouring cap that prevents the contents from dripping immediately even when the container body is displaced to an inclined position, and can stabilize the flow even when a large amount of contents is poured out by squeezing the container body. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a pouring cap comprising a cap body attached to the mouth of a squeezable container body and a top lid for opening and closing the cap body, the cap body comprising a partition wall for closing the mouth and having an opening for a pouring outlet, and a valve member formed inside the partition wall and provided with an inflow space into which the contents in the container body flow from a communicating passage, and a communicating passage that opens at a position eccentric to the pouring outlet, the partition wall comprising a flow straightening portion protruding from a position facing the communicating passage on the inflow space side, The valve member includes an outer peripheral wall attached to the cap body, a valve wall that closes the lower end of the outer peripheral wall and opens the communication passage, and a plurality of straightening ribs extending in the vertical direction on the inner periphery of the outer peripheral wall. The present invention employs a configuration characterized by the above.

[0008] As an embodiment of the straightening part of the pouring cap, a configuration is adopted in which the straightening part is characterized by being a curved recess protruding from the underside of the partition wall and recessed in the center, and a configuration is adopted in which the straightening part is characterized by being a plurality of straightening guide ribs formed radially from the center of the underside of the partition wall toward the hinge side.

[0009] Another embodiment of the dispensing cap includes: The top cover is The cap is connected to the cap body via a hinge. Effect of the Invention

[0010] By adopting the above-mentioned configuration, the dispensing cap of the present invention prevents the contents from dripping immediately even when the container body is displaced into an inclined position, and even when the container body is squeezed hard to dispense a large amount of contents, the contents can be caused to collide with the straightening section to stabilize the flow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] The pouring cap of the present invention will now be described with reference to the drawings in which the following embodiments are shown. In the following description, the left side in FIG. 1 is referred to as the "front side (opposite the hinge)", the right side is referred to as the "rear side (hinge side)", the upward direction is referred to as the "upper", and the downward direction is referred to as the "lower". EXAMPLES

[0013] In FIG. 1, A is a cap body attached to a container body E, B is an upper lid connected to the cap body A by a hinge C so as to be able to be opened and closed freely, and D is a valve member attached inside the cap body A. The container body E can be elastically deformed by squeezing the body (not shown) by hand, and an engaging protrusion 2 for attaching the cap body A is provided on the outer periphery of the mouth portion 1 of the container body E.

[0014] 1 and 2, the cap body A includes an attachment part 5 that is attached to the mouth part 1 of the container body E, and a partition wall 6 that extends inward from the attachment part 5 and closes the opening of the mouth part 1. The partition wall 6 has a spout 7 opened at a position of an axis O2 that is biased toward the front side (opposite the hinge C) from the central axis O1, and a spouting tube 8 erected from the periphery of the spout 7. A cylindrical attachment tube 9 is erected on the underside, and is formed with an inner diameter that includes the spout 7 inwardly with the axis O1 as the center, and a valve member D is attached to its inner circumference. A fitting recess 15 that fits with the outer periphery of the valve member D is provided on the inner circumference of the attachment tube 9.

[0015] The attachment portion 5 comprises an inner tube 11, the outer periphery of which is inserted into the inner periphery of the mouth portion 1 of the container body E, an outer tube 12, the inner periphery of which engages with the outer periphery of the mouth portion 1, and a ring-shaped lid engagement portion 13 which is connected to the upper ends of the inner tube 11 and outer tube 12 and which keeps the top lid B closed. The outer cylinder 12 has an engaging portion 14 on its inner periphery that engages with the engaging protrusion 2 of the mouth portion 1 .

[0016] A flow straightening portion 10 is provided on the lower surface of the partition wall 6 so as to protrude about a central axis O1 in order to straighten the flow of the contents. The flow straightening portion 10 is provided in a cylindrical shape so as to protrude from the lower surface of the partition wall 6, and the lower surface of the flow straightening portion 10 is formed as a curved recess 16 which is recessed deepest in the center and curved outward.

[0017] As shown in Figure 1, the top lid B has a flat top wall 20, a side wall 21 hanging down from the periphery of the top wall 20, and a sealing tube 22 hanging down from the front side rather than the center of the underside of the top wall 20, and the lower outer periphery of which is inserted into the inner periphery of the pouring tube 8 of the cap body A to seal when the lid is closed. A hinge C is connected to the lower end on the back side of the outer periphery of the side wall 21, and a knob 23 is provided on the front side. The lower end of the inner surface of the side wall 21 is provided with a locking portion 24 into which the lid engagement portion 13 of the cap body A fits to maintain the lid in a closed state.

[0018] As shown in Figures 1 and 3, the valve member D comprises an outer peripheral wall 25 whose outer periphery engages with the inner periphery of the mounting tube 9 of the cap body A, and a valve wall 26 which closes the bottom of the outer peripheral wall 25 and is flexible enough to be deformed by pressure, and a cross slit hole 27 is formed in the center of the valve wall 26 by a cross cut that penetrates in the vertical direction around the axis O1, and the cross slit hole 27 is opened from the center 27a by elastic deformation of the valve wall 26 to form a communicating passage between the inside and the outside, and the communicating passage may also be made capable of being closed off so as to be openable and closable.

[0019] A fitting protrusion 28 is provided on the outer periphery of the outer wall 25, which fits into a fitting recess 15 on the inner periphery of the mounting tube 9 of the cap body A, and a plurality of straightening ribs 29 (eight in this embodiment) extending in the vertical direction to straighten the flow of the contents are arranged at equal intervals around the circumferential direction on the inner periphery, although the number of straightening ribs 29 may be increased or decreased as necessary. Furthermore, a plurality of legs 25a extending downward are arranged at intervals in the circumferential direction at the lower end of the outer peripheral wall 25, but the legs 25a do not necessarily have to be provided.

[0020] Next, the manner of use and the effects of this embodiment will be described. First, in the present embodiment, the dispensing cap is formed by integrally molding the cap body A, the top cover B and the hinge C in the open state, and then attaching the separately molded valve member D to the mounting tube 9 of the cap body A, thereby forming a dispensing cap with the valve member D set therein. At that time, as shown in FIG. 1, an inflow space a is formed between the lower surface of the partition wall 6 of the cap body A and the inside of the valve member D.

[0021] Next, after setting the dispensing cap, the top lid B is rotated around the hinge C as a fulcrum to close the cap body A. The sealing tube 22 of the top lid B fits tightly against the dispensing tube 8 of the cap body A to form a seal, and the lid engagement portion 13 of the cap body A and the locking portion 24 of the top lid B fit together to close the lid. The closed pouring cap is attached to the mouth 1 of the container body E filled with the contents, forming a squeeze container fitted with the pouring cap. In this embodiment, the dispensing cap is attached to the container body E by plugging, but it may be attached by screwing.

[0022] When using the contents in the container body E, first, the top lid B is opened from the cap body A, and then the container body E is tilted and the body is squeezed to elastically deform it, thereby applying pressure to the contents in the container body E and directing the contents to the opening of the mouth 1. The valve wall 26 of the valve member D is pressed toward the inflow space a, causing the valve wall 26 to elastically deform, and the central portion 27a of the cross slit hole 27 is opened to become a communicating passage, allowing the contents to flow into the inflow space a.

[0023] As shown in Figure 4, the contents that flow into the inflow space a from the opening of the central portion 27a of the cross slit hole 27 mainly collide with the center of the curved recess 16 of the straightening section 10 protruding from the partition 6, and are diffused in all directions along the curved surface of the curved recess 16 and guided around the curved recess 16. Furthermore, the contents guided to the periphery of the curved recess 16 are rectified by a plurality of rectifying ribs 29 disposed along the inner periphery of the outer periphery wall 25 of the valve member D, and are filled into the inflow space a. As described above, the content that has flowed into the inflow space a from the opening of the cross slit hole 27 is guided into the pouring tube 8 from the pouring outlet 7 of the partition wall 6 of the cap body A, and is poured out.

[0024] In the cap body A and valve member D of this embodiment, when the contents in the container body E are used, by squeezing the body of the container body E, the valve wall 26 of the valve member D is deformed, and the contents flowing in from the central part 27a of the cross slit hole 27 first collide with the curved recess 16 of the straightening part 10 on the underside of the partition 6 of the cap body A, and then are straightened by the straightening rib 29 on the inner circumference of the outer wall 25 of the valve member D, filling the inflow space a, and then are poured out through the pouring outlet 7 of the partition 6 via the pouring tube 8, so that the contents can be reliably straightened within the inflow space a.

[0025] In the pouring cap of this embodiment, even if the cross slit hole 27 of the valve member D opens slightly due to the weight of the contents simply by tilting the container body E, the contents remain in the inflow space a before being poured out from the pouring outlet 7 through the pouring tube 8, so the contents do not immediately drip out from the pouring outlet 7. In addition, even if the body of the container body E is squeezed hard to open the central part 27a of the cross slit hole 27 widely and the contents are sprayed into the inflow space a, the flow is straightened within the inflow space a and the contents can be poured out stably without being suddenly sprayed out of the pouring tube 8. Therefore, by adjusting the strength of the squeeze, the contents can be adjusted to be poured out in small or large amounts stably from the pouring tube 8.

[0026] By squeezing the body of the container body E, the contents are stably dispensed from the dispensing tube 8 of the cap body A, and then when the squeezing is stopped, the pressure on the valve wall 26 stops, the deformation of the container body E is restored to its original shape, the cross slit hole 27 is closed, the flow into the inflow space a is stopped, and the dispensing from the dispensing tube 8 is stopped. When the top lid B is closed on the cap body A, the pouring tube 8 is inserted into the sealing tube 22 of the top lid B, and the inner side is sealed by the partition wall 6. The contents can be used repeatedly by opening the top cover B from the cap body A again and squeezing the body of the container body E. EXAMPLES

[0027] Next, a second embodiment in which the cap body A and the valve member D of the first embodiment are modified will be described. In the following, the same components as those in the first embodiment are given the same reference numerals, and only different components are given different reference numerals, and the differences will be mainly described.

[0028] In FIG. 5, Aa denotes a cap body attached to a container body E, B denotes an upper lid connected to the cap body Aa by a hinge C so as to be able to be opened and closed freely, and Da denotes a valve member attached inside the cap body Aa.

[0029] As shown in Figures 5 and 6, the cap body Aa has an attachment portion 5 that is attached to the mouth portion 1 of the container body E, and a partition wall 30 that extends inward from the attachment portion 5 and seals the opening of the mouth portion 1. The partition 30 has an outlet 7 opened at a position on an axis O2 that is biased toward the front from the central axis O1, and an outlet tube 8 is erected from the periphery of the outlet 7. The underside is formed with an inner diameter that includes the outlet 7 inwardly, centered on the axis O1, and has an attachment tube 9 vertically erected for attaching the valve member Da to its inner periphery, and the inner periphery of the attachment tube 9 is provided with an engagement recess 15 that engages with the outer periphery of the valve member Da.

[0030] A flow straightening portion 31 is provided on the lower surface of the partition 30 to protrude toward the rear side (hinge C side) from the central axis O1 in order to straighten the flow of the contents. The flow straightening portion 31 is formed of a plurality of flow straightening guide ribs 32 arranged from the center of the lower surface of the partition wall 30 toward the rear surface side. In this embodiment, as shown in FIG. 6(b), the flow straightening section 31 is composed of five flow straightening guide ribs 32 arranged at intervals from the center of the central side radially outward from the center of the central side on the underside of the partition wall 30 to the rear side.

[0031] As shown in Figures 5 and 7, the valve member Da comprises an outer peripheral wall 25 whose outer periphery engages with the inner periphery of the mounting tube 9 of the cap body Aa, and a valve wall 35 which closes the bottom of the outer peripheral wall 25 and is flexible enough to be deformed by pressure. When the valve member Da is mounted on the cap body Aa, the valve wall 35 has a U-shaped slit hole 36 formed by a U-shaped cut that extends from a central portion 36a located on the axis O3 on the rear side of the axis O1 along the outer peripheral wall 25 to both sides and penetrates in the vertical direction, and the U-shaped slit hole 36 is opened near the central portion 36a due to deformation of the valve wall 35, forming a communicating passage between the inside and the outside, and the communicating passage may be made to be able to be closed open and closed.

[0032] A fitting protrusion 28 is provided on the outer periphery of the outer periphery wall 25 to be fitted into the fitting recess 15 on the inner periphery of the mounting tube 9 of the cap body Aa. As in the first embodiment, a plurality of flow straightening ribs extending in the vertical direction for straightening the flow of the contents may be provided at equal intervals in the circumferential direction on the inner periphery of the outer periphery wall 25. Further, a plurality of legs 25a extending downward are provided at the lower end of the outer peripheral wall 25 at intervals in the circumferential direction.

[0033] Next, the manner of use and the effects of this embodiment will be described. First, the dispensing cap of this embodiment becomes a dispensing cap with the valve member Da set therein by mounting the valve member Da inside the mounting cylinder 9 of the cap body Aa. At that time, as shown in FIG. 5, an inflow space b is formed between the lower surface of the partition wall 30 of the cap body Aa and the inside of the valve member Da.

[0034] When using the contents in the container body E of this embodiment, first, the top lid B is opened from the cap body Aa, and then the container body E is tilted and the body is squeezed to elastically deform it, thereby applying pressure to the contents in the container body E and directing the contents to the opening of the mouth portion 1. The valve wall 35 of the valve member Da is pressed toward the inflow space b, whereby the valve wall 35 elastically deforms, opening the area near the central portion 36a of the U-shaped slit hole 36 to form a communicating passage, and the contents flow into the inflow space b.

[0035] As shown in FIG. 8, the contents flowing into the inflow space b from the opening near the center 36a of the U-shaped slit hole 36 mainly collide with the rear side of the multiple flow straightening guide ribs 32 of the flow straightening section 31 protruding from the partition wall 30, and are guided between the flow straightening guide ribs 32 from the rear side to the front side, where they are straightened, and fill the inflow space b. As described above, the content that has flowed into the inflow space b from the opening of the U-shaped slit hole 36 is guided into the pouring tube 8 from the pouring outlet 7 of the partition wall 30 of the cap body Aa, and is poured out.

[0036] In the cap body Aa and valve member Da of this embodiment, when the contents in the container body E are used, by squeezing the body of the container body E, the valve wall 35 of the valve member Da is deformed, and the contents flowing in from the opening near the central portion 36a of the U-shaped slit hole 36 collide with the back side of the flow straightening guide rib 32 on the underside of the partition 30 of the cap body Aa, are guided between the flow straightening guide ribs 32 from the back side to the front side, and are straightened. After filling the inflow space b, the contents are poured out through the pouring outlet 7 on the front side of the partition 30 via the pouring tube 8, so that the flow of the contents can be reliably straightened within the inflow space b.

[0037] As with the first embodiment, in the pouring cap of this embodiment, even if the U-shaped slit hole 36 of the valve member Da opens slightly due to the weight of the contents simply by tilting the container body E, the contents remain in the inflow space b before being poured out through the pouring outlet 7 and the pouring tube 8, so that the contents do not immediately drip out of the pouring outlet 7. In addition, even if the body of the container body E is squeezed hard to widen the central portion 36a of the U-shaped slit hole 36 and the contents are sprayed into the inflow space b, the flow is rectified within the inflow space b, and the contents can be poured stably without being suddenly sprayed out of the pouring tube 8. The other effects are the same as those of the first embodiment. [Industrial Applicability]

[0038] The pouring cap of the present invention forms an inflow space between the partition of the cap body and the inside of the valve member attached to the cap body, and the contents are caused to flow into the inflow space by pressing and deforming the valve wall of the valve member, and the flow is rectified within the inflow space, allowing the contents to be poured stably from the pouring outlet of the cap body.Therefore, the pouring cap of the present invention is suitable as a pouring cap to be attached to a squeeze container which squeezes and pours the contents.
