Description

  The present invention relates to a hinge cap attached to a mouth portion of a container, and particularly to a hinge cap provided with a flow rate adjusting mechanism.

Conventionally, a cap having a dispensing cylinder for dispensing contents is attached to the mouth of a container. As this type of cap, there is known a hinge cap including a cap body attached to a mouth portion of a container and a lid body that can be opened and closed with the cap body via a hinge.
This type of hinge cap tilts the container and pours out the contents through the dispensing cylinder. If the amount is small, the tilt is reduced, but it is difficult to adjust the tilt of this container.If the tilt is too much, the contents may come out too much or the contents may jump out in an unexpected direction, and it is necessary to adjust the flow rate. Become.
Therefore, a hinge cap provided with a flow rate adjusting mechanism in the cap body of the hinge cap has been conventionally known (see, for example, Patent Document 1).

Japanese Patent No. 5085357

However, although the hinge cap flow rate adjustment mechanism described in Patent Document 1 is excellent in workability during assembly, the outlet holes and the outside air introduction holes are provided equally in the circumferential direction, and the functions of both can be separated. In addition, since the relationship between the opening areas of the two is not considered, there is a problem that the flow rate adjustment is not sufficient.
In addition, if the content liquid remains in the flow rate adjusting mechanism after pouring, there is a problem that the residual liquid is ejected before the content liquid and becomes dirty during re-pouring.

An object of the present invention is to solve the above problems, and when the content liquid is poured out, the flow rate can be adjusted and poured out, and even if the pouring angle changes, the flow rate of the content liquid does not change much, and An object of the present invention is to provide a hinge cap provided with a flow rate adjusting mechanism capable of adjusting the flow rate without being influenced by fluctuations in the pouring direction and allowing the content liquid to be poured in a concentrated manner at the place of use.
It is another object of the present invention to provide a hinge cap that can be quickly returned to the container without the content liquid remaining in the flow rate adjusting mechanism after the dispensing.

  In order to solve the above-described problems, the present invention provides a hinge cap including a cap body attached to a mouth portion of a container as a hinge cap and a lid attached to the cap body via a hinge.

In this embodiment, as shown in FIGS. 1 and 2, a flow rate adjusting mechanism E integrated with the cap body A from the lower end portion 5 a of the dispensing cylinder 5 is provided.
The flow rate adjusting mechanism E has a peripheral wall 20 that is suspended inwardly from the lower end portion 5a of the dispensing cylinder 5 and a bottom wall 23 that extends inward from the lower end portion of the peripheral wall 20. doing.
As shown in FIG. 1 (b), in the range α (approximately 180 °) on the opposite side of the hinge C of the peripheral wall 20, a plurality of apertures formed in a slit shape in the longitudinal direction at intervals in the circumferential direction. 21 is provided. In the present embodiment, seven openings 21 are provided at seven locations, and all have the same opening area at equal intervals.
In addition, the number of the apertures 21 can be increased or decreased as necessary.
Further, at least one air replacement hole 22a is provided in a range β (approximately 180 °) of the peripheral wall 20 on the hinge C side. In the present embodiment, one air replacement hole 22a and two auxiliary openings 22b (having the same opening area as the opening 21) are provided, and two or more air replacement holes 22a are provided. It is only necessary to ensure a size that allows air replacement.
In this embodiment, the total opening area of all the seven openings 21 is set smaller than the opening area of the air replacement hole 22a. When this condition is satisfied, the dispensing of the content liquid becomes stable.
When two or more air replacement holes 22a are provided, the total opening area of all the apertures 21 may be set smaller than the total opening area of all the air replacement holes 22a.
The opening areas of the opening 21 and the air replacement hole 22a of the present embodiment are as follows. However, in the flow rate adjusting mechanism E, the outer diameter of the bottom wall 23 is 20 mm, and the height of the peripheral wall 20 is 5 mm.

The sealing member 24 is formed on the upper end of the outer peripheral wall portion 9 of the cap main body A in a horizontally long arc shape on both sides along the outer periphery from the central portion opposite to the hinge C. The sealing member 24 is formed from the center thereof. A locking piece 25 extending upward, a notch portion 26 on both sides for locking a claw portion 37 provided on the lid B, which will be described later, and knobs 27 formed on both ends are provided.
The knob 27 is provided so as to extend upward from the side of the handle portion 35 provided on the lid B. Further, a bendable vertical groove 38 is provided between the knob piece 27 and the adjacent locking piece 25.
The sealing member 24 is integrally provided on the outer peripheral upper end of the outer peripheral wall portion 9 via a breakable central weakened portion 28 and both end weakened portions 29 extending in the circumferential direction of the outer peripheral upper end of the outer peripheral wall portion 9.

An arc-shaped handle portion 35 is provided in the middle of the outer periphery of the side peripheral wall 31 of the lid B on the side opposite to the hinge C. The handle recess 35 a is located at a position corresponding to the locking piece 25 of the sealing member 24. Further, the handle portion 35 is provided with a finger hook portion 39.
The side peripheral wall 31 is provided with claw portions 37 protruding from both sides and below the handle portion 35.

  The lid B is pivotally attached to the upper peripheral upper end of the outer peripheral wall 9 of the cap body A via a hinge C, and the top wall 30 and the side suspended from the peripheral edge of the top wall 30 are attached. The peripheral wall 31 is formed at the lower portion of the side peripheral wall 31 as a large-diameter portion 31a having the same diameter as the outer peripheral wall portion 9 of the cap main body A. 32 is suspended.

  On the inner periphery of the cylindrical wall 32, a stopper 32a is provided in the circumferential direction for holding the plug F so as to be movable up and down within a predetermined range.

As shown in FIG. 1, the plug F is for sealing the dispensing tube 5 when the lid is closed, and is configured as a separate member from the cap body A and the lid B.
The plug F is composed of a disc-shaped plug base 40 and a sealing ring 41 that is suspended from the lower surface of the plug base 40 and is fitted into the inner periphery of the dispensing cylinder 5 of the cap body A from the tip 41a. ing.

A peripheral protrusion 42 and a ring-shaped protrusion 43 are formed on the upper surface peripheral portion and upper surface central portion of the plug base 40, respectively. In the closed state, the upper surface of the peripheral protrusion 42 is the top wall 30 of the cover B. The upper surface of the ring-shaped protrusion 43 is in contact with or close to the inner surface of the top wall 30.
For this reason, when the lid is closed, an upper gap 44 surrounded by the peripheral protrusion 42 is formed between the upper surface of the plug base 40 and the inner surface of the top wall 30.

Next, usage modes and operational effects of this embodiment will be described.
The hinge cap of the present embodiment needs to be assembled with the plug body F on the cylindrical wall 32 of the lid B before the first closing process, and the inner circumference of the cylindrical wall 32 with the lid B opened. When the plug body F is pushed into the outer periphery, the outer peripheral surface of the plug body base 40 gets over the retaining portion 32 a on the inner periphery of the cylindrical wall 32 and is held by the cylindrical wall 32.

  The hinge cap according to the present embodiment has a relationship between the lid engaging portion 7 of the cap body A and the lid B before the hinge cap is attached to the container D or in an unopened state after the hinge cap is attached to the container D. In addition to the engagement of the mating recess 34, the claw portion 37 of the lid B is engaged with the upper surface of the cutout portion 26 of the sealing member 24, whereby the closed state can be maintained more firmly.

Next, as shown in FIG. 1, the closed hinge cap is plugged into the mouth portion 1 of the container D filled with the content liquid and attached.
In the plugging process, the mouth portion 1 of the container D is applied to the annular groove formed between the inner cylinder 8 and the outer peripheral wall portion 9 of the mounting portion 3, and a pressing force is applied from the top of the lid B, The engagement protrusion 10 of the wall portion 9 is fitted over the fitting protrusion 2 of the mouth portion 1, and the mouth portion 1 of the container D is connected to the outer periphery of the inner cylinder 8, the inner periphery of the outer peripheral wall portion 9, and the lid member. It is mounted by being sandwiched between the joint portions 7.

When the hinge cap is first opened in order to pour and use the content liquid in the container D, the finger is applied to either the left or right knob 27 of the sealing member 24 of the cap body A shown in FIG. And pull it forward.
By pulling either the left or right side of the tab 27 of the sealing member 24, the both ends weakened portion 29 on that side is broken from either the left or right direction, and the central weakened portion 28 is also broken. The piece 25 is removed from the grip recess 35a, and the sealing member 24 is completely separated from the cap body A.

  Next, if the handle 35 of the lid B is lifted and the sealing ring 41 of the plug F linked to the lid B is removed from the dispensing cylinder 5 of the cap body A, the container D is simply tilted. The content liquid in the container D can be easily poured out from the dispensing cylinder 5.

In the present embodiment, since the flow rate adjusting mechanism E is provided in the hinge cap, the content liquid in the container D is poured out from the dispensing cylinder 5 with the flow rate adjusted.
Air replacement holes 22a are provided on the hinge C side of the peripheral wall 20, and when the container D is tilted, air is fed into the container D, and a plurality of air replacement holes 22a are provided in the peripheral direction on the opposite side of the peripheral wall 20 from the hinge C. From the opening 21, the content liquid is taken into the flow rate adjusting mechanism E, and the content liquid whose flow rate has been adjusted is poured out through the dispensing cylinder 5. Since the flow rate is adjusted, the behavior of the content liquid generated by tilting the container D can be relaxed and poured out with a gradual change, and the content liquid does not come out excessively.
In addition, although the opening 21 mainly functions to adjust the flow rate, the opening 21 apart from the dispensing direction may function to replace air. The auxiliary opening 22b mainly functions as air replacement, but may function as flow adjustment when close to the dispensing direction.
In the present embodiment, a large number of openings 21 are provided over a range α on the side opposite to the hinge C at intervals in the circumferential direction, and two auxiliary openings 22b are provided in the range β on the hinge C side. Therefore, not only the direction opposite to the hinge C but also the dispensing with the flow rate adjusted is possible not only when the dispensing direction swings left and right.
When the pouring is finished, the content liquid is returned into the container D through the opening 21, the air replacement hole 22 a and the auxiliary opening 22 b of the inclined peripheral wall 20, and the content liquid hardly remains in the flow rate adjusting mechanism E.
If the content liquid is poured out only on the side opposite to the hinge C, the auxiliary opening 22b is unnecessary, and a necessary number is provided near the air replacement hole 22a for air replacement. Alternatively, the width of the air replacement hole 22a can be increased.

  By closing the lid B again on the cap body A, the outer periphery of the sealing ring 41 of the plug body F held on the cylinder wall 32 of the lid B is engaged with the inner periphery of the pouring cylinder 5 of the cap body A. The cap body A can be sealed, and the lid B can be opened and closed repeatedly after the hinge cap is opened.

The hinge cap of the present embodiment can be disposed of after being completely used from the contents liquid in the container D and then discarded from the mouth 1 of the container D.
In that case, when the hinge cap is opened, the lid B is gripped with a finger and pulled outward, the connected portion of the outer peripheral wall 9 with the hinge C is pulled and deformed, and the longitudinal tear line When the lid is broken and the lid B is further pulled, the connecting portion 19 forming the circumferential tear line starts to break. When the breakage of the connecting portion 19 proceeds, the lid body B moves away from the cap body A.
When the cutting of the connecting portion 19 is completed up to the end portion of the slit groove 16 and the lid B is further pulled, the cap body A and the mouth portion 1 of the container D are disconnected, and the hinge cap and the container D are separated. Can be discarded.

Further, in this embodiment, although not shown, a partition wall may be provided at the spout and covered, and a pull ring may be erected on the partition wall via a support column. In that case, it is possible to form the spout by unclamping the weakened portion provided in the partition wall. The shape of the spout is preferably formed along the lower end 5 a of the spout cylinder 5.
Moreover, although the separate plug body F was used in the present embodiment, it is also possible to seal the pouring cylinder 5 of the cap body A using a sealing cylinder suspended from the inner surface of the top wall 30 of the lid B. Is possible.

Next, a second embodiment in which the configuration of the flow rate adjusting mechanism E is changed will be described with reference to FIG.
Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, the changed portions of the flow rate adjusting mechanism E will be denoted by new symbols, and differences will be mainly described.

As shown in FIG. 4, the flow rate adjusting mechanism E of the present embodiment is the same as the first embodiment except that the peripheral wall 50 is vertical and the bottom wall 53 is a mountain shape that is inclined upward toward the center. It is.
Since the bottom wall 53 of the present embodiment has a mountain shape that is inclined upward toward the center, the content liquid remaining on the upper surface of the bottom wall 53 after pouring flows quickly from the center of the bottom wall 53 toward the periphery, Since it returns to the inside of the container D through the opening 21, the air replacement hole 22a, and the auxiliary opening 22b, the residual liquid does not jump out and stain the outside of the container D at the time of re-pouring.
About another structure, it is the same as that of 1st Example, and an effect is also the same.

Next, a third embodiment in which the configuration of the flow rate adjusting mechanism E is changed will be described with reference to FIG.
Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, the changed portions of the flow rate adjusting mechanism E will be denoted by new symbols, and differences will be mainly described.

As shown in FIG. 5, in the flow rate adjusting mechanism E of the present embodiment, the peripheral wall 60 is vertical as in the second embodiment, and the bottom wall 63 is moved downward from the opposite side of the hinge C toward the hinge C side. The configuration other than the slightly inclined flat plate is the same as that of the first embodiment.
Since the bottom wall 63 of the present embodiment is slightly inclined from the side opposite to the hinge C toward the hinge C side, the content liquid remaining on the top surface of the bottom wall 63 after the pouring is placed on the inclined surface of the bottom wall 63. Therefore, the remaining liquid does not jump out and stain the outside of the container D at the time of re-pouring, because it flows back into the container D through the air replacement hole 22a having a large opening area.
About another structure, it is the same as that of 1st Example, and an effect is also the same.

The hinge cap of the present invention is provided with a flow rate adjusting mechanism E provided with an opening and an air replacement hole whose opening area is specified around the peripheral wall in the cap body, so that even when the container is largely inclined, the hinge cap protrudes. The amount dispensed changes slowly and is dispensed in a stable state. Further, even when the dispensing direction is deviated laterally, stable dispensing with the flow rate adjusted similarly becomes possible. It is particularly suitable when the content liquid has a low viscosity.
Also, the hinge cap of the present invention quickly returns the content liquid remaining in the flow rate adjustment mechanism E into the container after being poured out, so that the residual liquid in the flow rate adjustment mechanism is ejected when re-pouring. No contamination outside the container.
