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. [Background technology]

[0002] Conventionally, in a pouring cap attached to a so-called squeeze container, the contents are expelled by squeezing the body of the container with the hand and return to their original state when the container is released. In such a case, when the container is tilted from an upright position, the contents sometimes drip out of the pouring tube.

[0003] For this reason, a dispensing cap is known that is equipped with a discharge valve that opens and closes a communication port in response to fluctuations in the internal pressure of the container when the container is squeezed, switching the communication port between open and closed (see Patent Document 1), so that liquid does not immediately drip when the container 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 dispensing valve is coaxial with the central axis of the container, while the dispensing outlet is positioned toward the front of the central axis of the container. Therefore, when the container is squeezed hard to eject a large amount of the contents, the contents flow in an uneven direction from the dispensing valve along the inner circumference of the inner stopper to the underside of the top wall, causing disturbances in the flow of the contents, which can cause them to splash around from the dispensing outlet.

[0006] The present invention has an object to solve the above problems and to provide a pouring cap for a squeeze container that does not drip when the squeeze container is merely tilted and can suppress the momentum of the content liquid even when the container is squeezed strongly. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a pouring cap for a squeeze container, comprising a cap body attached to the mouth of the squeeze container and an upper lid connected to the cap body via a hinge, the cap body comprising a partition wall that closes the mouth and opens the pouring outlet, a pouring tube portion that penetrates the partition wall from the periphery of the pouring outlet in the vertical direction, and a valve member attached to the inlet side of the pouring tube portion and opens and closes the pouring outlet, the pouring tube portion comprising a baffle portion with which the liquid flowing in from the valve member collides, and a straightening protrusion formed on the outlet side of the baffle portion and for collecting the liquid flow diffused around the baffle portion to the center.

[0008] In an embodiment of the pouring cap for a squeeze container, the pouring tube portion includes an upper pouring tube standing upright from the partition wall and a lower attachment tube hanging down from the lower end of the upper pouring tube below the partition wall. The upper cover includes a top wall and a sealing tube hanging down from the lower surface of the top wall to seal the upper pouring tube. The lower attachment tube includes a baffle plate portion formed in the center at a predetermined distance from the inner peripheral surface on the inflow side and an annular flow straightening protrusion inclined upward from the inner peripheral surface on the outflow side. The baffle plate portion is connected to the inner peripheral surface of the lower attachment tube by a plurality of connecting portions, and includes a lower flat surface portion having a flat lower portion and a mountain-shaped portion having a convex upper portion. The valve member includes an attachment tube attached to the lower outer periphery of the pouring tube portion of the cap body, and a cross slit-shaped valve body that closes the lower end of the attachment tube and opens due to the pressurized liquid flow. Effect of the Invention

[0009] By adopting the above-mentioned configuration, the squeeze container dispensing cap of the present invention does not drip when the squeeze container is merely tilted, and when dispensing the contents in the container, even if the container is squeezed hard, the momentum of the contents can be suppressed and the contents can be dispensed in a rectified state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Next, the pouring cap of the present invention will be described with reference to the drawings showing the embodiments. In the following description, when viewed in Figure 2(a) with the lid closed, the left direction is referred to as the "front side (opposite the hinge)", the right direction is referred to as the "rear side (hinge side)", the upward direction is referred to as "upper", and the downward direction is referred to as "lower".

[0012] (Example) In Figures 1 and 2(a), A is a container, B is a cap body attached to container A, D is a top cover attached to cap body B via hinge C in an openable and closable manner, and E is a valve member that closes the opening of cap body B. The body of the container A is made of a soft material that can be deformed by pressure so as to push out the liquid content, the valve member E is made of an elastically deformable material such as an elastomer, and the cap body B, hinge C and top lid D are integrally molded from a material harder than the valve member E, such as LLDPE (linear low density polyethylene). The materials of each can be changed as appropriate. Container A has a mouth 1 at its upper part, and a fitting protrusion 2 is provided on the upper outer circumferential surface of mouth 1.

[0013] As shown in Figures 1 and 2(a), the cap body B has an attachment portion 3 that is fitted into the mouth portion 1 of the container A, and a partition wall 4 that extends inward from the inner edge of the attachment portion 3 and seals the opening of the mouth portion 1. The partition 4 has a pouring outlet 4a opened at a position closer to the front side (opposite the hinge) than the center, and a pouring tube portion 5 is formed which penetrates the partition 4 vertically from the periphery of the pouring outlet 4a.

[0014] The mounting portion 3 is composed of a base wall portion 6 that abuts against the upper surface of the mouth portion 1 of the container A, an inner tube 7 that hangs down from the inner side of the base wall portion 6, and an outer peripheral wall portion 8 that hangs down from the outer peripheral side of the base wall portion 6. A lid engagement portion 9 is erected on the upper part of the base wall portion 6, and its upper surface and outer periphery engage with an upper lid D. A hinge C is connected to the upper part of the back side (hinge side) of the outer periphery of the outer peripheral wall portion 8, and an engagement protrusion 10 is provided at the lower inner periphery for engaging with a mating protrusion 2 of the mouth portion 1 of the container A.

[0015] On the upper part of the outer peripheral wall portion 8, on the front side, there is a stepped recess 11 recessed in an arc shape from the outer periphery over an arc range of approximately 180°, and on the remaining back side, the upper surface 8a is flush with the upper surface of the partition wall 4. The step recess 11 is formed with a flat surface 11a that is lower than the top surface 8a, an inclined surface 11b that slopes upward and inward from the inner peripheral edge of the flat surface 11a, and inclined side surfaces 11c that slope from both sides of the end of the flat surface 11a toward both sides of the top surface 8a.

[0016] As shown in FIG. 1(a), near the left of hinge C of outer wall portion 8 (approximately 35° left from the center of the back side), an outer circumferential cut-out portion 12 that is approximately V-shaped in a plan view is cut into the outer circumferential surface from the upper surface 8a, leaving a thin bottom wall 13 at the lower end. As shown in Figures 1(a) and 4(a), at a position corresponding to the outer peripheral cut portion 12 of the engaging protrusion 10 on the inner circumference of the outer peripheral wall portion 8, an inner peripheral cut portion 14 is engraved from the lower end of the inner circumference to include the engaging protrusion 10, and this portion of the outer peripheral wall portion 8 is cut from inside and outside to make it thin, and a vertical weakened portion 15 is formed that is connected to the thin-walled bottom wall 13 and forms a vertical tear line. On the back side of the outer peripheral cut-out 12 on the top surface 8a of the outer peripheral wall portion 8, a slit groove 16 is recessed from the top surface 8a, starting from a position separated by the thin-walled portion on the upper inner peripheral side of the end face 12a and extending circumferentially to the inclined side surface 11c of the step recess 11 on the right end side of the top surface 8a, and the part outside the slit groove 16 on the top surface 8a is an arc wall portion 17 that connects to the hinge C, and the front side portion of the outer peripheral cut-out 12 on the top surface 8a (the part adjacent to the outer peripheral cut-out 12) is a thick-walled portion 18 that integrally connects the upper part of the outer peripheral wall portion 8 and the lower part of the base wall portion 6.

[0017] As shown in Figures 1 and 4, the bottom surface 19 of the slit groove 16 is recessed deepest from the top surface 8a from the end face 12a side to the center of the hinge C (line O-X2 in Figure 1(a)) as bottom surface 19a as shown in Figure 4(b), and is formed so that the height from the top surface 8a gradually becomes shallower from the center of the hinge C toward the right at approximately 45° (line O-X3 in Figure 1(a)) as shown in Figure 4(c), and finally, as shown in Figure 4(d), the inclined side surface 11c of the step recess 11 is cut out to connect to the end of the flat surface 11a (line O-X4 in Figure 1(a)). As shown in FIG. 1, the inner circumferential side of the bottom surface 19 constitutes a thin-walled lower lateral weakened portion 20 that connects the outer circumferential wall portion 8 from the end face 12a side to the center of the hinge C to the lower wall portion of the base wall portion 6, and is provided with an arc-shaped connecting portion 21 that slopes upwardly inward from the inner circumferential edge of the bottom surface 19 that slopes upward from the center of the hinge C to the end of the inclined surface 11b of the step recess 11.

[0018] At the upper inner periphery of the outer wall portion 8, from the left side to the center of the back side, a thin-walled lower lateral weakened portion 20 is formed, as shown in Figures 1 and 4(b), and from the center of the back side to the right side, a thin-walled inclined connecting weakened portion 22 that rises in line with the height of the sloping bottom surface 19, as shown in Figures 1 and 4(c), and on the front side, in the range of the step recess 11, an upper lateral weakened portion 23 is formed, which is thin-walled, between the outer periphery of the base wall portion 6 and the inclined surface 11b of the step recess 11, as shown in Figures 1 and 4(d). The lower lateral weakened portion 20, the inclined connecting weakened portion 22 and the upper lateral weakened portion 23 are formed in sequence and continuous to each other, forming a circumferential tear line.

[0019] A finger hook recess 24 is recessed downward from the flat surface 11a of the step recess 11 over a predetermined range on the front side of the outer periphery of the outer periphery wall portion 8.

[0020] As shown in Figures 1 to 3, the pouring tube portion 5 is provided with an upper pouring tube 25 which is erected upward from the partition wall 4 around the periphery of the pouring outlet 4a and which guides the content liquid outward, and a lower mounting tube 26 which is suspended downward from the lower end of the upper pouring tube 25 below the partition wall 4 and has a valve member E attached to its outer periphery. In this embodiment, the upper end of the pouring upper tube 25 is formed into a trumpet shape to make it easier to pour the content liquid, and the inner circumference is formed with a lower inner circumference 25b which is formed with a narrowed diameter at the bottom, and an upper inner circumference 25a which expands in diameter and extends upward from the upper end of the lower inner circumference 25b.

[0021] The mounting lower tube 26 has a fitting portion 27 formed on the lower outer periphery to prevent the valve member E from falling off, and a baffle plate portion 29 formed in the center at a distance α from the inner periphery on the lower inner periphery, and a plurality of connecting portions 30 (formed in two places in this embodiment) connecting the inner periphery of the mounting lower tube 26 and the side of the baffle plate portion 29 are formed on the lower inner periphery. Furthermore, the attached lower tube 26 has an annular straightening protrusion 28 that slopes upward from the inner surface above (on the outflow side of) the baffle plate portion 29 on the inner circumference in order to collect the liquid flow that has been diffused to the periphery by the baffle plate portion 29 to the center. The lower part of the baffle plate portion 29 is formed as a flat lower plane portion 29a, and the upper part is formed as a mountain-shaped portion 29b that is raised from the periphery toward the center, and the periphery of the baffle plate portion 29 is open as a communicating passage 31, except for the part blocked by the connecting portion 30. On the inner periphery of the mounting lower cylinder 26, an outflow space β is formed between the flow straightening protrusion 28 and the mountain-shaped portion 29b of the baffle plate portion 29, and an inflow space γ is formed between the lower flat surface portion 29a of the baffle plate portion 29 and the lower end portion of the mounting lower cylinder 26. Note that the flow straightening protrusion 28 may be a protrusion that bulges inwardly, and does not have to be inclined upward.

[0022] As shown in Figures 1 to 3, the valve member E is composed of an attachment tube 35 that is attached to the outer periphery of the attachment lower tube 26 of the pouring tube portion 5 of the cap body B, and a valve body 36 that extends inward from the lower inner periphery of the attachment tube 35 and seals the inside of the attachment tube 35. The inner periphery of the attachment tube 35 is formed with an engagement protrusion 37 that engages with the engagement portion 27 on the outer periphery of the attachment lower tube 26 of the cap body B, and the valve body 36 is formed with a cross slit 38 in the center.

[0023] The upper surface of the valve body 36 closes the inflow space γ in the attached lower cylinder 26, and when the container A is squeezed, the center of the cross slit 38 is pressed and deformed, forming an open slit valve. In this embodiment, the periphery of the cross slit 38 is made thicker than the other walls so that the valve can be quickly restored when closed and does not open easily. Note that the slit structure is not limited to a cross shape, and a straight line shape or the like may be used as long as it does not cause liquid to drip when the squeeze container is tilted.

[0024] As shown in Figures 1 to 3, the upper lid D is rotatably attached to the upper outer end of the outer wall portion 8 of the cap body B via a hinge C, and is provided with a top wall 40, a side wall 41 that hangs down from the periphery of the top wall 40 and has the hinge C connected to its outer periphery, and a sealing tube 42 that hangs down from a predetermined position on the underside of the top wall 40 and seals the upper pouring tube 25 of the pouring tube portion 5, and a ring-shaped portion 43 is provided on the outer periphery of the sealing tube 42 of the top wall 40, which is recessed from the underside and hollowed out, and which can be deformed.

[0025] An engagement recess 45 is provided around the inner periphery of the lower end of the side peripheral wall 41 to engage with the lid engagement portion 9 to maintain the lid in the closed state. An arc-shaped covering wall 46 is vertically attached to the front outer edge of the underside of the side peripheral wall 41, and is formed so that its lower end is close to or abuts the flat surface 11a of the step recess 11 so as to cover the step recess 11 of the outer wall portion 8 of the cap body B when the lid is closed. A knob 47 having an arc shape is formed in the circumferential direction at the lower end on the front side of the outer periphery of the side peripheral wall 41, and a hinge C is connected to the lower end on the rear side.

[0026] The outer periphery of the sealing cylinder 42 forms a normal seal portion a which is inserted into the upper inner periphery 25a of the upper pouring tube 25 of the pouring tube portion 5 when the lid is closed to create a sealed state, and the lower outer periphery of the sealing cylinder 42 is reduced in diameter to provide the lower sealing cylinder 42a, and the outer periphery of the lower sealing cylinder 42a is formed so as to be close to or in contact with the lower inner periphery 25b when the lid is closed, and a temporary seal portion b is formed by the outer periphery of the lower sealing cylinder 42a and the lower inner periphery 25b.

[0027] In order to prevent unauthorized opening before use, the dispensing cap of this embodiment may have a shrink label or sealing member or the like provided between the cap body B and the top lid D, although this is not shown.

[0028] Next, the manner of use and the effects of this embodiment will be described. The squeeze container dispensing cap of this embodiment is integrally molded in the open state shown in FIG. The molded pouring cap has an upper cover D rotated via a hinge C to cover the cap body B, and is closed as shown in FIG. 2(a). At that time, the lower part of the outer peripheral surface of the sealing tube 42 of the upper cover D adheres closely to the upper inner circumference 25a of the upper pouring tube 25 of the pouring tube portion 5 of the cap body B to form a sealed portion a, and the outer circumference of the lower sealing tube 42a comes close to or abuts against the lower inner circumference 25b to form a temporary sealed portion b. Furthermore, the engaging recess 45 of the side peripheral wall 41 of the top lid D and the lid engaging portion 9 of the cap body B engage with each other, maintaining the lid closed.

[0029] Next, the valve member E is attached to the lower mounting tube 26 of the pouring tube portion 5 of the cap body B from below. At this time, the inner periphery of the mounting cylinder 35 of the valve member E engages with the outer periphery of the mounting lower cylinder 26, and the fitting protrusion 37 of the mounting cylinder 35 engages with the fitting portion 27 of the mounting lower cylinder 26, so that the valve member E is mounted so as not to fall off. Further, the valve body 36 of the valve member E closes the lower end of the lower mounting cylinder 26 and the inflow space γ therein.

[0030] Next, the closed pouring cap is attached to the mouth 1 of the container A filled with the liquid content. In the stoppering process, the annular groove formed between the inner tube 7 and outer peripheral wall 8 of the attachment part 3 is set into the mouth 1 of the container A from above, and a pressing force is applied from above the top lid D, so that the engaging protrusion 10 of the outer peripheral wall 8 overcomes the mating protrusion 2 of the mouth 1 and fits into it, and the mouth 1 of the container A is clamped between the outer periphery of the inner tube 7, the inner periphery of the outer peripheral wall 8, and the base wall part 6 and attached.

[0031] When the cap is closed and dropped upside down, even if an impact force is applied to the top wall 40 of the upper lid D, the ring-shaped portion 43 absorbs the impact received by the upper lid D and does not push the sealing cylinder 42 into or pull it away from the pouring tube portion 5, so that the adhesion between the sealing cylinder 42 and the pouring tube portion 5 of the cap body B is not affected, and the sealing cylinder 42 and the pouring tube portion 5 are prevented from coming loose and from damaging each other.

[0032] When using the liquid contents in container A, first place your hand on handle 47 of top lid D and lift it up relative to cap body B, which releases the seal between sealing tube 42 of top lid D and upper pouring tube 25 of pouring tube portion 5 of cap body B, and disengages side wall 41 of top lid D from lid engagement portion 9 of cap body B, thereby opening top lid D relative to cap body B. Even if container A is tilted forward with the lid open, the liquid contents in container A are sealed by the underside of partition 4 of cap body B and valve member E, as shown in Figure 5(a), so the liquid contents will not drip out.

[0033] When container A is tilted forward with the lid open, the tip of the pouring tube portion 5 is directed toward the desired pouring location, and the body of container A is squeezed by hand to pressurize the inside of container A. As shown in Figure 5(b), the pressurized liquid content pushes the valve body 36 of the valve member E from the inside to the outside, deforming the cross slit 38 from the center and opening it. Next, the content liquid passes through the opening of the cross slit 38, flows into the inflow space γ of the attached lower cylinder 26, passes through the communicating passage 31 formed on the outer periphery of the baffle plate portion 29, flows into the outflow space β, passes through the inner periphery of the straightening protrusion 28, flows into the inner periphery of the pouring upper cylinder 25, and is discharged from the tip of the pouring upper cylinder 25.

[0034] At this time, in the pouring cap of this embodiment, the liquid flow that is pressurized and flows into the inflow space γ from the center of the cross slit 38 hits the lower flat surface 29a of the baffle plate portion 29, and while spreading outward, is guided to the communication passage 31 with the interval α. Next, the liquid flow guided from inside the communication passage 31 into the outflow space β is guided to the inner circumferential surface of the straightening protrusion 28, is guided inside the upper pouring cylinder 25 so as to gather at the center, and is discharged from the tip of the upper pouring cylinder 25. In this way, the flow of the content liquid is guided by the lower flat surface 29a of the baffle plate portion 29, the communicating passage 31, and the inner surface of the straightening protrusion 28, so that even if the body of the container A is squeezed hard, the momentum of the liquid flow is attenuated and the content liquid does not spurt out from the tip of the upper pouring tube 25 with force like a water gun, but can be stably discharged as intended from the tip of the upper pouring tube 25.

[0035] When the hands are removed from the body of container A and the squeezing is stopped, the deformation of the body of container A returns to its original shape, negative pressure is created inside container A, the liquid in the container A no longer presses against the valve body 36 of the valve member E, and the deformation of the central portion of the cross-shaped slit 38 returns to its original shape and closes, as shown in Figure 5(a).

[0036] At this time, due to the negative pressure within the container A, the liquid content remaining above the valve body 36 is sucked back into the container A through the small opening of the cross slit 38 of the valve body 36. In the pouring cap of this embodiment, the liquid content remaining in the upper pouring tube 25 flows from the straightening protrusion 28 into the outflow space β, and is guided to spread outward quickly due to the inclination of the mountain-shaped portion 29b of the baffle plate portion 29, is guided to the communicating passage 31 with the gap α, flows within the inflow space γ, and returns to the container A through the small opening of the cross slit 38, so that the liquid content can be quickly recovered. In addition, since the communication passage 31 has only a small opening area formed on the outer circumferential side of the baffle plate portion 29 excluding the connecting portion 30, the liquid content does not block the communication passage 31 unless liquid pressure is applied, and the remaining liquid content does not drip out.

[0037] By closing the upper lid D again on the cap body B, the lower part of the outer peripheral surface of the sealing tube 42 of the upper lid D comes into close contact with the upper inner circumference 25a of the upper pouring tube 25 of the cap body B to form sealed portion a, and the outer circumference of the lower sealing tube 42a comes close to or abuts the lower inner circumference 25b to form temporary sealed portion b, thereby sealing the inside of the container A. The pouring cap can repeatedly open and close the upper lid D and squeeze the container A to dispense the liquid contents.

[0038] Next, a mode in which the pouring cap is separately disposed of after the liquid content in the container A has been completely used will be described. In this case, the pouring cap is opened, and the top cover D is grasped with the fingers and pulled outward, whereby the back side of the arc wall portion 17, which is the connecting portion with the hinge C of the outer peripheral wall portion 8, is pulled outward via the hinge C, thereby pulling and deforming the back side of the connected outer peripheral wall portion 8.

[0039] When the top cover D is pulled further, the vertical weakened portion 15 breaks from above, and the adjacent thin-walled bottom wall 13 also breaks, breaking the vertical tear line, and the lower horizontal weakened portion 20 is cut circumferentially from the end face 12a side connected to the vertical weakened portion 15, and then the continuous inclined connecting weakened portion 22 begins to break. As the lower lateral weakened portion 20 is cut and the fracture of the inclined connecting weakened portion 22 progresses, the upper cover D and the cap body B connected thereto are partitioned by the lower lateral weakened portion 20 and the inclined connecting weakened portion 22, and the lower side of the fractured outer peripheral wall portion 8 is separated from the cap body B.

[0040] Next, when the inclined connection weakened portion 22 is completely broken, the continuous upper horizontal weakened portion 23 is broken from the right end, and finally passes through the step recess 11 and is stopped by the thick portion 18. In the pouring cap of this embodiment, when the inclined connection weakened portion 22 is cut, it is inclined from bottom to top to match the inclination of the bottom surface 19, so that the force pulling the lower portion of the outer peripheral wall portion 8 is directed upward, making it easier for the force to be applied and easier for it to break.

[0041] Furthermore, when the broken outer peripheral wall portion 8 is pulled, the thick portion 18 of the connected outer peripheral wall portion 8 is pulled outward, disengaging the engaging protrusion 10 of the outer peripheral wall portion 8 of the cap body B from the mating protrusion 2 of the mouth 1 of the container A, and when it is raised in this state upward, the upper side and its inner side of the outer peripheral wall portion 8 connected by the thick portion 18 are lifted, and the cap body B is removed from the mouth 1 of the container A, allowing the pouring cap and container A to be separated. [Industrial Applicability]

[0042] The pouring cap for a squeeze container of the present invention does not drip when the squeeze container is simply tilted, and when discharging the contents inside the container, even if the container is squeezed hard, the momentum of the contents can be suppressed and the contents can be discharged in a rectified state, making it suitable as a pouring cap for a squeeze container.
