JP 2007-1637 A

In the case of a content liquid that shakes and uses a container such as a dressing in a cap with a relatively weak seal pressure between the dispensing cylinder and the sealing cylinder, such as the cap of the liquid dispensing container described in Patent Document 1 above, When shaken, there is a concern that the content liquid may jump out of the spout, hit the seal portion between the discharge tube and the sealing tube, and leak from the seal portion.
In addition, even when the cap is not completely closed accidentally, even if it is a cap that does not leak due to the impact of liquid, the sealing pressure of the dispensing cylinder and the sealing cylinder is sufficiently strong when the lid is completely closed. If the container is shaken or if the container is shaken with an insufficient seal, the liquid content may leak out to the outside, causing the surroundings of the container to become dirty.

  The present invention aims to solve the above problem, even if the seal between the pouring cylinder of the cap body and the sealing cylinder of the lid is weak, or even if the container is shaken in a state where the lid is not completely closed, It is an object of the present invention to provide a cap for a liquid dispensing container in which the content liquid does not leak or scatter.

In order to solve the above-described problems, the present invention provides a cap body that is attached to a mouth portion of a container as a cap of a liquid dispensing container, and a lid that is engaged with a lid engaging portion of the cap body to seal the inside of the container. In the cap of the liquid dispensing container comprising the body, the cap body includes a dispensing tube standing up around the dispensing opening in a partition wall forming a dispensing opening communicating with the inside of the container, and a lid Is provided with a sealing cylinder whose bottom end is in close contact with the inner peripheral surface of the dispensing cylinder when the cap body is engaged, and is inside the dispensing cylinder and has a dispensing opening. Around the periphery, inclined fins are provided that form wall surfaces that are inclined inwardly and project upward. On the upper surface of the partition wall between the outer wall surface of the inclined fins and the inner peripheral surface of the extraction cylinder, inward A liquid recovery inclined surface that is inclined downward is formed, and the inclined fin has a liquid recovery inclined surface at a plurality of locations in the circumferential direction. Adopting the structure, characterized in that provided notches functioning as a flow path passing.

As a specific embodiment of the cap of the liquid pouring container, the partition wall is inclined, and is connected to the pouring cylinder on one side, and is connected to the other side on the other side. Adopts a configuration characterized in that there is no notch portion other than one notch portion also serving as a content liquid pouring channel.

  As another embodiment of the cap of the liquid dispensing container, the lid is connected to the cap body via a hinge, and further over a predetermined arc range on the hinge side at the inner peripheral lower end of the sealed cylinder The structure is characterized in that a flange portion that projects obliquely downward is provided, and the tip of the collar portion extends inward from the tip position of the inclined fin in plan view when closed, and the outer periphery of the lower end of the sealing cylinder When the lid is engaged with the lid engaging portion of the cap body, an engaging end portion that forms a sealing surface in close contact with the inner peripheral surface of the extraction cylinder protrudes from the surface. When the lid is rotated and closed around the hinge, it engages with a temporary engagement protrusion that protrudes on the opposite side of the hinge on the inner peripheral surface of the extraction cylinder without contacting the inner peripheral surface of the extraction cylinder. The structure characterized by this is adopted.

  The cap of the liquid pouring container according to the present invention is provided with an inclined fin that forms a wall surface that is slanted inward and protrudes upward around the pouring opening, so that a container for storing dressing, various kinds of sags, etc. When mixing the content liquid by shaking the container at the time of use, the slanted fins concentrate the content liquid that pops out from the dispensing opening near the center of the back of the lid body. Even if the seal is weak or the lid is not completely engaged with the lid engaging portion of the cap body and the seal is incomplete, leakage of the content liquid can be prevented.

In addition, a liquid recovery inclined surface is formed on the upper surface of the partition wall between the outer wall surface of the inclined fin and the inner peripheral surface of the dispensing cylinder, and cuts that serve as flow paths communicating with the liquid recovery inclined surface at a plurality of circumferential positions of the inclined fin. In the embodiment in which the notch portion is provided, the content liquid jumping out from the dispensing opening and the content liquid adhering to the back surface of the lid or the dispensing cylinder can be efficiently collected in the container.
In addition, the partition wall is inclined and connected to the dispensing cylinder at one side, and at the other side, the other side is connected to the other side. In the embodiment in which only one location also serves as a flow path, liquid does not easily remain on the liquid recovery inclined surface on the higher side of the partition wall, and when the container is tilted to pour out the content liquid, the residual liquid is more than the content liquid. Since it does not flow out first and contaminates the surroundings, the number of notches can be reduced, so that the liquid content is less likely to scatter and leakage can be further reduced.

In the embodiment in which the lid is connected to the cap body via a hinge, and the flange portion projecting obliquely downward is provided at the lower end of the inner periphery of the sealed cylinder, the collar portion flows down the sealed cylinder when the lid is opened and closed. The residual liquid is received and the surroundings are not soiled.
Further, the engagement end projecting on the outer peripheral surface of the lower end of the sealing cylinder engages with the temporary engagement protrusion projecting on the side opposite to the hinge on the inner peripheral surface of the extraction cylinder, thereby temporarily closing the cover. In the embodiment that can be performed, even if the lid is not completely closed by engaging with the lid engaging portion of the cap body, the inclined fin is provided, so that the container is shaken in the temporarily closed state. Even if the content liquid is mixed, the content liquid will not leak.

As shown in FIG. 3A, a temporary engagement protrusion 21 protruding inward is provided on the inner peripheral surface of the dispensing cylinder 6 on the side opposite to the hinge C over a predetermined arc range.
In this embodiment, the circular arc range has a circumferential angle α of about 30 °, but is not limited to 30 ° and can be appropriately determined.
Further, as in the modification shown in FIG. 3B, the temporary engagement protrusions 21 may be provided on both sides of the vicinity of the center serving as the flow path of the content liquid poured out from the container.

A thin inclined fin 22 is provided around the dispensing opening, that is, on the partition wall 7 surrounding the weakened portion 17 to form a wall surface that is inclined inward and protrudes upward.
On the upper surface of the partition wall 7 between the outer wall surface of the inclined fin 22 and the inner peripheral surface of the dispensing tube 6, a liquid recovery inclined surface 23 that is inclined downward toward the inside is formed. Cutout portions 24 that are cut out at a predetermined width in the circumferential direction are provided so as to form flow paths that communicate with the liquid recovery inclined surface 23 at a plurality of locations in the circumferential direction.
In the present embodiment, the notch portions 24 are provided at eight locations at equal intervals, but the location and number of the notch portions 24 can be determined as appropriate. However, on the side opposite to the hinge C, a notch 24 is always disposed to form a flow path when the content liquid is poured out from the container.

The lid B includes a top wall 30 and an outer peripheral wall 31 suspended from the periphery of the top wall 30, and a hinge C is continuously provided at a predetermined position at the lower end of the outer periphery of the outer peripheral wall 31.
On the back surface of the top wall 30, a sealing cylinder 32 fitted into the inner periphery of the extraction cylinder 6 of the cap body A is suspended.

As shown in FIGS. 2 and 4, a reduced diameter protrusion 35 projecting inward is provided on the inner periphery of the lower end of the outer peripheral wall 31. An upper engaging surface 35a that engages with the annular bulging portion 14 of the engaging portion 12 is formed, and is further continuous with the diameter-enlarged concave ridge portion 36 into which the annular bulging portion 14 is fitted.
In addition, a lower contact surface 35b that contacts the inclined surface 15 on the upper portion of the annular bulging portion 14 is formed at the lower portion of the reduced diameter projecting ridge portion 35 when temporarily closed, and the inclination is increased toward the lower end of the outer peripheral wall 31.

An engagement end portion 38 that protrudes in an annular shape is provided at the lower end of the outer periphery of the sealing cylinder 32, and a sealing surface can be formed between the inner peripheral surface of the dispensing cylinder 6 to seal the inside of the container. It is like that.
The lower end of the inner periphery of the sealing cylinder 32 is provided with a flange portion 39 that projects obliquely downward over a predetermined arc range centered on the hinge C side, and the tip thereof is viewed in a plan view when the lid is closed. The inclined fin 22 extends inward from the tip position.
Here, the closed state means only when the annular bulging portion 14 of the cap main body A is fitted into the enlarged diameter concave portion 36 of the lid body B and engaged with the reduced diameter protruding portion 35. Not including the time of temporary closing when the engagement end portion 38 is engaged with the temporary engagement protrusion 21.

  The positional relationship between the reduced diameter protrusion 35 of the lid B and the annular bulging portion 14 of the cap body A, and the engagement end 38 of the lid B and the temporary engagement protrusion 21 of the cap body A is reduced. When the lower contact surface 35b of the strip 35 is in contact with the inclined surface 15 of the annular bulging portion 14, the engagement end 38 gets over the temporary engagement protrusion 21, and the upper portion of the engagement end 38 is temporarily engaged. It arrange | positions so that it may be in the temporarily closed state engaged with the lower part of the joint protrusion 21. FIG.

Next, usage modes and operational effects of this embodiment will be described.
In order to attach the hinge cap to the container body D, the lid body B in the opened state shown in FIG. 2 is closed to obtain a completely closed state as shown in FIG.
When closing the lid B, first, the sealing cylinder 32 is fitted and inserted into the inner periphery of the pouring cylinder 6, and as shown in FIG. A temporarily closed state where the lower abutment surface 35b of the reduced diameter protrusion 35 abuts against the inclined surface 15 of the upper portion of the annular bulging portion 14 while receiving sliding resistance when the temporary engagement protrusion 21 is overcome. Become.
When the cover B is further closed by applying a force, the reduced diameter protrusion 35 gets over the annular bulging portion 14 and the upper engagement surface 35a becomes the annular bulging portion 14 as shown in FIG. To form a sealing surface, and the enlarged-diameter groove portion 36 is fitted to the annular bulging portion 14 to be in a completely closed state.
At this time, the engagement end portion 38 of the sealing cylinder 32 is in close contact with the inner peripheral surface of the dispensing cylinder 6 to form a sealing surface.

Next, the mouth portion 1 of the container body D is applied to the annular groove between the inner cylinder 9 and the outer cylinder 10 of the hinge cap that is completely closed, and is pressed from the upper part of the lid B to be plugged.
At the time of stoppering, the engaging ridge 13 of the outer cylinder 10 gets over the annular ridge 3 of the mouth 1 and engages with the mouth 1, and the cap body A is attached to the mouth 1 of the container body D.

When using the container, put a finger on the knob 37 of the lid B and lift it upward to release the engagement between the reduced diameter protrusion 35 and the annular bulging portion 14, and further engage the sealing cylinder 32. The engagement between the end portion 38 and the temporary engagement protrusion 21 is also released, and the lid B is opened.
Next, the pull ring 19 is pulled upward, the weakened portion 17 is broken, the removed portion 18 is cut off, and the dispensing opening is opened.
If the container is held and tilted, the content liquid is guided to the dispensing cylinder 6 through the dispensing opening and can be poured out of the container.

When the content liquid is dressing or various kinds of soot and sag, it is used after closing the lid and shaking the container before mixing the content liquid. In this embodiment, the partition 7 is poured out. Since the inclined fins 22 are formed around the opening so as to form wall surfaces that are inclined inwardly and project upward, the content liquid that is ejected from the dispensing opening when the container is shaken is The center of the lid B can be concentrated.
For this reason, the liquid is not applied to the sealed portion between the sealing cylinder 32 and the dispensing cylinder 6, and the container is placed in a state where the sealing between the sealing cylinder 32 and the dispensing cylinder 6 is weak or not completely closed by mistake. Even if it is shaken, leakage of the content liquid can be prevented.

Further, in this embodiment, when the lid B is closed, the engaging end portion 38 of the sealing cylinder 32 gets over the temporary engaging protrusion 21 of the dispensing cylinder 6 and the lower abutting surface of the reduced diameter protrusion 35. 35 b abuts on the inclined surface 15 at the upper portion of the annular bulging portion 14, and the repulsive force due to the engagement between the upper portion of the engagement end portion 38 and the lower portion of the temporary engagement protrusion 21, and the lower portion of the reduced diameter ridge portion 35. The repulsive force due to the contact between the contact surface 35b and the inclined surface 15 of the annular bulging portion 14 is balanced and the engaged state is maintained, so that the temporarily closed state can be obtained.
Thus, even if the container is shaken in a temporarily closed state where the sealed cylinder 32 and the dispensing cylinder 6 are not sealed, leakage of the content liquid can be prevented by the inclined fins 22.

In the temporarily closed state, the engagement force between the engagement end portion 38 and the temporary engagement protrusion 21 is relatively small, so that it can be easily opened and closed even by children and elderly people with weak fingertips. Convenient for frequent use.
In particular, in a container that is heat-treated by heat filling or the like, the engagement force between the reduced diameter protrusion 35 and the annular bulging portion 14 in a completely closed state is large so that the lid is not opened due to an increase in internal pressure due to heating. Since it is set, when it is used frequently, it is easy to open and close and easy to use if it is in a temporarily closed state.

Furthermore, in the present embodiment, a liquid recovery inclined surface 23 that is inclined downward toward the inside is formed on the upper surface of the partition wall 7 between the outer wall surface of the inclined fin 22 and the inner peripheral surface of the dispensing cylinder 6, Since the fins 22 are provided with the notches 24 serving as flow paths communicating with the liquid recovery inclined surface 23 at a plurality of locations in the circumferential direction, the content liquid that has jumped out from the dispensing opening can be efficiently recovered in the container. .
Since the notch 24 is always arranged on the side opposite to the hinge C, the inclined fin 22 does not get in the way when the content liquid is poured out.

The liquid adhering to the back surface of the lid B when the container is shaken may flow down from the hinge C side of the sealing cylinder 32 when the lid B is tilted during opening and closing, but in this embodiment, the sealing cylinder 32 is used. Since a flange portion 39 that protrudes obliquely downward over a predetermined arc range centered on the hinge C side is provided at the lower end portion of the inner periphery of the inner peripheral portion, when the lid body B is opened and closed, the residual liquid is generated in the flange portion 39. There is no such thing as getting caught in the surroundings.
The tip of the collar portion 39 extends inward from the tip position of the inclined fin 22 in a plan view when the lid is closed, that is, when the lid is completely closed or temporarily closed, so that the liquid is quickly collected in the container. can do.

  When the container is used and moved from the dining table or the like and stored in the refrigerator or the like, the lid B is moved until the expanded diameter concave portion 36 is fitted to the annular bulging portion 14 by further applying force from the temporarily closed state. It can be moved and stored after it is closed and fully closed.

In this embodiment, the lid B is a hinge cap connected to the cap body A via a hinge C. However, like the cap of the liquid dispensing container described in Patent Document 1, the lid engaging portion is A cap that is a screw or a cap that uses other engaging means may be used.
In that case, it is needless to say that a configuration based on the assumption of a hinge cap such as the temporary engagement protrusion 21 and the flange portion 39 in this embodiment cannot be adopted.
Moreover, when a lid | cover engaging part is a screw, it is good also as a lid | cover engaging part by providing a screw | thread in the outer periphery of the extraction | pouring cylinder.

Next, a description will be given of a second embodiment in which the configuration of the notch is changed in accordance with the change in the configuration of the partition wall.
Hereinafter, the same reference numerals are given to the same components as in the first embodiment, and the description will focus on the differences. As shown in FIG. 5, in this embodiment, the partition wall 7 of the container body A is on the hinge C side. It is formed so as to be inclined downward, and is continuous with the extraction tube 6 that is high on the side opposite to the hinge C and low on the hinge C side.
Further, the notch 24 of the inclined fin 22 includes only a notch 24a that also serves as a liquid discharge channel and a notch 24b on the half circumferential surface on the hinge C side. This is different from the first embodiment in that it is not provided except for the notch 24a.

  In this embodiment, since the partition wall 7 is inclined downward toward the hinge C side, the content liquid remaining on the liquid recovery inclined surface 23 flows down to the hinge C side according to the inclination. The cut-out portion 24b may be provided at several places or one place on the half-circumferential surface on the hinge C side, and the cut-out portion 24a that also serves as a content liquid discharge channel is provided on the half-circumferential surface opposite to the hinge C. Need only be provided.

  In this way, it is difficult for the liquid to remain on the liquid recovery inclined surface 23 on the side opposite to the hinge C from which the content liquid is poured out, and when the container is tilted to pour out the content liquid, the residual liquid is When the container is shaken in a temporarily closed state where the sealed cylinder 32 and the dispensing cylinder 6 are not sealed, the sealed cylinder 32 and the dispensing are not discharged. Since there is only the notch 24a on the side opposite to the hinge C where the gap between the cylinder 6 and the cylinder 6 is large, the liquid content is more difficult to scatter and further prevents liquid leakage from the gap between the sealed cylinder 32 and the extraction cylinder 6. There is.

Moreover, although it can be said not only in the second embodiment but also in the first embodiment, if the temporary engagement protrusion 21 shown in FIG. Since the protrusion 21 also serves as a breakwater for the content liquid that jumps out from the notch 24a for pouring the content liquid, it is possible to further prevent liquid leakage from the gap between the sealed cylinder 32 and the extraction cylinder 6. .
Other functions and effects are the same as those of the first embodiment.

  The cap of the liquid dispensing container of the present invention is provided with an inclined fin around the dispensing opening, and the seal between the dispensing cylinder and the sealing cylinder of the lid is weak or the lid is not completely closed As the contents liquid is not leaked or scattered even if the container is shaken, the cap of the container containing the contents liquid to be mixed by shaking the container before use, such as dressing and various types It can be suitably used.
