Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a nozzle-type cap body which is assembled in a liquid container and has a measuring function.

[Conventional technology]

Conventionally, a nozzle-type cap body having a metering function, which is attached to a liquid storage container, is provided with a content in order to satisfactorily pour out the content liquid as shown in Japanese Utility Model Publication No. 55-27662. In addition to the pouring cylinder for pouring out the liquid, an air cylinder for introducing air into the container body is hung from the partition wall of the cap body.

By providing this air cylinder, compared with the case where a hole for air intake is simply opened in the partition wall, it is possible to prevent the content liquid from leaking illegally from this air hole when pouring out the content liquid. Demonstrate.

[Problems to be solved by the invention]

However, the air cylinder provided in the cap body is
It does not mean that the length may be arbitrarily set.

That is, if the air cylinder is too long, the handling of the cap body becomes troublesome, and when the cap body is assembled to the container body, the air cylinder interferes with the work efficiency in the assembly process. is there.

On the other hand, if the air cylinder is too short, there is a problem that the content liquid leaks out from the air cylinder when the content liquid is poured out and is wasted, and the cap body, the container body, or other articles are contaminated.

From the above points, the length of the air cylinder needs to be set to the required dimension.

The problem here is the deviation of the cap body from the fixed position with respect to the container body. This fixed position for assembly means that the container body is installed with the cap body attached to the mouth tube of the liquid storage container body whose tilting direction when pouring out the content liquid is regulated substantially accurately due to attachment of a handle or the like. When tilted in a regulated direction, the air hole is located directly above the spout, and refers to the assembly position of the cap body with respect to the container body mouth tube.The deviation from this assembly fixed position is the container of the cap body. It is caused by uneven tightening force on the main body, molding dimensional error of the cap body and the container body, difference in wall thickness of the packing body assembled to the cap body, and the like. Fig. 2 shows the displacement of the assembly of the cap body with respect to the container body. In the figure, θ represents the predicted maximum displacement angle of the assembly and, from a large number of collected data, a maximum of 30 °. It is a degree.

When the cap body is displaced from the fixed position with respect to the container body, even if an air cylinder is provided, the content liquid leaks from the air cylinder in advance when the content liquid is poured out. In order to prevent the content liquid from leaking from the air cylinder even if there is a deviation from the fixed position with the assembly, this means that the length of the air cylinder becomes longer than necessary. This has been a problem in handling as described above.

Therefore, the present invention has been devised to solve the above-mentioned problems in the prior art, and the proper length of the air cylinder is determined according to the maximum deviation angle from the predicted assembly fixed position of the cap body with respect to the container body. It is a technical object to be able to set the height of the air cylinder. Therefore, it is an object of the present invention to obtain a cap body which is advantageous in handling and is in a good use condition by keeping the length of the air cylinder within an appropriate value range.

[Means for solving problems]

Means of the present invention for solving the above technical problem is a cap body that is attached to a mouth tube of a liquid storage container body in which a tilt direction at the time of pouring a content liquid is substantially accurately controlled by attaching a handle or the like, A partition 4 that vertically separates the assembly-equipped cylinder 3 is provided in the cylindrical assembly-equipped cylinder 3, and an outlet 5 for pouring the internal solution into the partition 4 and an air hole 6 for supplying air into the container body are provided. A cap body 1 having a spout cylinder 7 extending from the partition wall 4 extending from the partition wall 4, and a spout cylinder 7 extending from the partition wall 4 extending upright from the partition wall 4. Has a topped cylindrical measuring cup body 2 that fits and assembles into the upper part of the assembling cylinder 3 of the cap main body 1, and the length of the air cylinder 8 of the cap main body 1 is regulated by the container main body. The air hole 6 of the cap body 1 is located directly above the spout 5 in a state of being inclined in the direction, 5 ° of the cap body 1 from a fixed position where the cap body 1 is assembled to the container body
Predicted maximum assembly misalignment angle y within ~ 30 °
, And y is set from the relation of y = 5x−25.

[Action]

A cap body 1 which is filled with a fixed amount of content liquid (using a liquid detergent) and has an air cylinder 8 with a length x of 11 mm
The assembling position of the container body with respect to the container body is variously changed from the assembling fixed position, and the container body is slowly tilted in the regulated direction for each displacement angle, and the content liquid is poured out from the pouring cylinder 7. The following table shows the result of an experiment conducted on the presence or absence of leakage of the content liquid from the air cylinder 8 during the operation.

In this experiment result table, the mark ○ indicates that the content liquid did not leak from the air cylinder 8 at the time of pouring the content liquid, the mark Δ indicates that the content liquid partially leaked, and The cross indicates
It shows that a lot of content liquid has leaked out.

Under the same conditions, set the length x of the air cylinder 8 of the cap body 1 to 9 m
Experiments were carried out within the range of m to 13 mm, and the relationship between the length x indicated by ○ and the assembly deviation angle y was plotted on the graph. The relationship shown in FIG. 3 was obtained. It has been found that there is a relationship of y = 5x-25 between the length x and the assembly misalignment angle y.

If the assembly deviation angle y is 5 ° or less, all the experimental results are marked with a circle regardless of the length x. On the contrary, if the assembly deviation angle y is about 40 ° or more, the length x is Even if the size is increased according to the above relationship, it is not possible to prevent the content liquid from leaking out from the air cylinder 8, and all the experimental results are marked with an X.

By setting the length x of the air cylinder 8 according to the relation of y = 5x−25, it is not clear why leakage of the content liquid from the air cylinder 8 can be prevented, but the content liquid from the air cylinder 8 cannot be leaked. At the initial stage of pouring out the content liquid that may cause leakage, that is, when the container body is filled with a fixed amount of the content liquid, the height position of the line of sight of the content liquid is constant, so the container body is regulated. When it is tilted in the direction indicated by the arrow, the content liquid enters the pouring cylinder 7, the whole area of the extraction port 5 is blocked by the content liquid, the content liquid enters the air cylinder 8, and the entire lower end opening of the air cylinder 8 is closed. It is considered that clogging with the content liquid occurs sequentially, and all the opening portions are closed with the content liquid prior to the pouring of the content liquid.

That is, when the content liquid is poured out by pushing the invasion of the content liquid into the pouring cylinder 7 while all the opening portions are closed by the content liquid, a negative pressure is generated in the container main body, and this negative pressure is generated. Since the content liquid in the air cylinder 8 is pulled back by the pressure, it is considered that the content liquid does not leak from the air cylinder 8.

This action is achieved by increasing the length x of the air cylinder 8 so that the clogging of the air cylinder 8 with the content liquid, that is, the clogging of the opening portion of the container body with all the content liquid is achieved earlier. When the content liquid intrudes into the air cylinder 8 early because the negative pressure generated in the container main body before the content liquid is poured out from the pouring cylinder 7 becomes large and the assembly misalignment angle y is large. Even with this negative pressure, the air cylinder 8
It is assumed that the liquid inside will not be pulled back and leak.

The usage pattern is the same as the conventional one, in which the container body is tilted in the regulated direction into the measuring cup 2 removed from the cap body 1, and the content liquid is poured out through the pouring tube 7 of the cap body 1. At this time, even if the assembling position of the cap main body 1 with respect to the container main body is deviated from the assembling fixed position, the length x of the air cylinder 8 of the cap main body 1 is predicted to occur in advance. Since it is formed corresponding to y, the content liquid does not leak from the air cylinder 8, and proper and satisfactory pouring of the content liquid can be achieved.

That is, although the predicted maximum assembly deviation angle y obtained from a large number of collected data is 30 °, the relationship of y = 5x−25 is suitably applied to this assembly deviation angle y of 30 °. Since it is within the range of 5 ° to 30 °,
Even if the cap body 1 is assembled to the container body at a large assembly deviation angle y, the length x of the air cylinder 8 corresponds to the expected maximum assembly deviation angle y, and y = 5x-25. By setting in accordance with the relationship, it is possible to obtain a good pouring operation without leakage of the content liquid from the air hole 6.

The measuring cup body 2 after use is assembled to the cap body 1. At this time, since the measuring cup body 2 fits the lower part of the peripheral wall 9 thereof into the upper part of the assembling cylinder 3 of the cap body 1,
The content liquid adhered and remaining on the inner surface of the measuring cup body 2 does not flow down to the outer surface of the cap body 1, but flows down from the inner peripheral surface of the assembling cylinder 3 in the cap body 1 onto the partition wall 4 and the air holes 6 And return to the inside of the container body.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

The measuring cup body 2 has a topped cylindrical shape and is provided with a thread at the lower end of the outer peripheral surface. A fitting piece 10 is provided around the thread. Between the fitting piece 10 and the peripheral wall 9, the fitting piece 10
A gap 13 is formed in the upper end of the assembling cylinder 3 so as to facilitate elastic fitting and tight fitting.

An outer brim-shaped brim piece 11 having a seal strip 12 projectingly provided on the lower surface is provided around the upper edge of the outer peripheral surface of the fitting piece 10, and when the measuring cup body 2 is assembled to the cap body 1. The collar piece 11 is brought into close contact with the upper end surface of the assembling cylinder 3 of the cap body 1 to achieve and maintain the seal between the cap body 1 and the measuring cup body 2 in the assembled state.

A groove 14 is formed in the threaded portion at the lower end of the measuring cup body 2 to form an escape path for air inside when the measuring cup body 2 is assembled to the cap body 1.

Further, since the fitting piece 10 has a form projecting to the outer peripheral surface of the peripheral wall 9, it serves as a catching portion when the measuring cup body 2 is handled, whereby the measuring cup body 2 is provided.
Can be handled well.

The upper half of the inner peripheral surface of the assembling cylinder 3 of the cap body 1 is provided with a thread to which the measuring cup body 2 is screwed and assembled,
Further, a thread for screwing and assembling to the mouth tube of the container body is also provided in the lower half of the inner peripheral surface of the assembling cylinder 3 partitioned by the partition wall 4.

A large number of locking pieces 11 are provided at the lower end of the inner peripheral surface of the assembled cylinder 3, and the locking pieces 11 are locked to the container body side and screwed into the mouth tube of the container body. This is for preventing rotation of the cap main body 1 with the combination in the screwing direction.

The partition wall 4 has an upper surface that is inclined downward toward the air hole 6, and the content liquid located on the upper surface of the partition wall 4 is transferred to the air hole 6
It can be returned to the inside of the container body through.

According to the experimental results of many actual use examples according to the illustrated embodiment, the maximum deviation angle y of assembly of the cap body 1 with respect to the container body is about 20 ° at the maximum, so that the air cylinder 8 The length x of the cap is 9mm, and there is no inconvenience when handling the cap body 1 with a margin of 10-11mm.
It seems that the degree is effective.

[Effect of device]

Since the present invention has the above-mentioned configuration, it has the following effects.

Since the length of the empty cylinder is set to a value that can reliably prevent the leakage of the content liquid from this air cylinder,
The surrounding liquid is not polluted by the liquid content leaking from the empty cylinder, and no discomfort is caused, so that a satisfactory and comfortable liquid content pouring operation can be obtained.

Since the length of the empty cylinder can be minimized within the range that does not cause leakage of the content liquid, this air cylinder is too long, and handling such as storage, transportation, etc., and handling during assembly to the container body are troublesome. Therefore, smooth and efficient handling can be obtained.
