Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap attached to a mouth of a container.

[0002]

2. Description of the Related Art Conventionally, a cap fitted to the mouth of a container filled with a liquid seasoning such as lard oil has a lid for closing a spout when not in use. Such a cap is generally made of a soft synthetic resin, and when the lid is opened, the lid removed from the cap body is supported by an elastically deformable hinge so as not to be lost. When the lid is closed, the operability is good because the lid is covered on the upper surface of the cap body in accordance with the deformation of the hinge.

FIG. 10A and FIG.
In the example of Japanese Patent No. 75557, the cap 100 attached to the mouth 122 of the container 120 is a cylindrical cap body 104 provided with a spout 102 and a pressing portion 103 on the top.
And a lid 108 connected to the cap body 104 by a thin hinge 106.

In this case, a closure plug 126 having a pull ring 124 is also attached to the upper end of the mouth 122 of the container 120. Before use, the cap 100 is once removed from the container 120, and the pull ring 124 is pulled up to close the closure plug 12.
By removing 6, the mouth 122 can be opened.

In order to completely close the lid 108 placed on the cap body 104 via the hinge 106, the lid 108
The lid 108 can be locked to the cap body 104 by pushing the inside of the peripheral portion 108A into the lid engaging step portion 104A formed on the upper surface of the cap body 104 so that the lid 108 can be locked to the cap body 104. 104
Is almost closed, and at the same time, the spout 102 is also closed to prevent leakage of seasonings and entry of foreign substances.

[0006]

However, in the above-described cap 100, after the seasoning is poured, the cap 108 is covered with the lid 108, or the cap 100 is left in the vicinity of the spout 102 due to an impact at the time of locking. There is a high possibility that the spiced seasoning scatters and adheres to the pressing portion 103 and the like. Also, even if it does not scatter, the remaining seasoning flows through the upper portion of the cap body 104 from near the spout 102 due to vibrations and the like when stirring the seasoning in the container, and wraps around the pressing section 103 to contaminate the pressing section 103. There is also a risk that it will.

[0007] For this reason, there is a problem in that the finger is soiled when the pressing portion 103 is operated, and it is troublesome to wipe off the seasoning attached to the pressing portion 103.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a cap that prevents liquid in a container remaining in the vicinity of a spout from adhering to a pressing portion due to an impact when the lid is closed.

[0009]

According to the first aspect of the present invention, there is provided a body attached to a mouth of a container and sealing the mouth.
A pressing portion provided on an upper surface of the main body portion and elastically deformed when pressed to pressurize the liquid in the container; and a spout provided on a side surface of the pressing portion and discharging the pressurized liquid. A partition that partitions the pressing portion and the spout; a lid that covers an upper surface of the main body together with the spout; and a lid that is provided inside the lid and covers the upper surface of the main body. And an auxiliary wall portion slidably in contact with the wall surface of the partition portion in a state in which the partition wall portion is in a folded state.

According to the first aspect of the present invention, when the lid for covering the upper surface of the main body is closed together with the spout, the auxiliary wall provided inside the lid forms the partitioning portion for separating the pressing portion from the spout. The upper space of the main body, which is in sliding contact with the wall surface and covered by the lid, is divided into a pressing part side and a spout side.

For this reason, even if the residual liquid remaining in the vicinity of the spout after the liquid is poured is scattered due to the impact at the time of closing the lid, the scattered drops are blocked by the partition wall and the auxiliary wall, and the space on the spout side is blocked. Stay within. Further, even when the container is shaken to stir the liquid in the container, the residual liquid flowing from the vicinity of the spout to the pressing portion is blocked by the partition wall and the auxiliary wall.

This prevents the liquid from adhering to the pressing portion and prevents the pressing portion from being stained by the liquid.

According to a second aspect of the present invention, in the cap according to the first aspect of the present invention, the cap has a hinge portion for connecting the lid portion to the main body so as to be openable and closable. It is characterized by being erected along the opening and closing direction of the lid.

According to the second aspect of the present invention, when opening and closing the lid connected to the main body by the hinge, the auxiliary wall moves along the operating direction of the lid that opens and closes with the hinge as a fulcrum. Similarly, it comes into sliding contact with a partition provided along the opening and closing direction of the lid, or separates from the sliding contact. This reduces the frictional resistance between the partition and the auxiliary wall, and does not hinder the operation of opening and closing the lid. Further, good adhesion between the partition wall and the auxiliary wall is maintained.

Further, for example, even in a cap having the above-mentioned hinge portion and further urging the lid portion toward the main body portion by an urging means such as an elastic member, the lid portion can be smoothly opened and closed. Furthermore, the impact at the time of closing the lid is increased by the urging force on the lid by the urging means, and even if the liquid splatters violently, the auxiliary wall is in sliding contact with the side wall of the partition,
Droplets flying from the vicinity of the spout toward the pressing portion are reliably prevented from entering the space on the pressing portion side.

According to a third aspect of the present invention, in the cap according to the first or second aspect, the partition is formed so as to cross an upper surface of the main body, and the auxiliary wall is formed of the lid. It is characterized in that it is formed so as to cross the inside of the part.

According to the third aspect of the present invention, the partition wall formed so as to cross the upper surface of the main body portion is slidably contacted with the auxiliary wall portion formed so as to cross the inside of the lid portion. The contact width (area) between the wall surface and the auxiliary wall portion is increased.

In a case where a load is applied to the hinge portion due to a twist of the lid or the like, a contact portion between the partition wall portion and the auxiliary wall portion functions as a resistance portion to the torsional force (rotational moment). However, by increasing the contact width, a large resistance to twisting force can be obtained. As a result, the load applied to the hinge is greatly reduced, and damage to the hinge can be prevented.

According to a fourth aspect of the present invention, there is provided a main body which is attached to a mouth of a container and seals the mouth, and which is provided on an upper surface of the main body and is elastically deformed when pressed to remove liquid in the container. A pressing portion for pressurizing, a spout provided on a side surface of the pressing portion, for discharging the pressurized liquid, a lid covering the upper surface of the main body together with the spout, and an upper surface of the main body Alternatively, it is characterized in that it has a partition provided on one of the insides of the lid to partition the pressing portion and the spout when the lid covers the upper surface of the main body.

According to the fourth aspect of the present invention, when the lid covers the upper surface of the main body, the lid is partitioned into the pressing portion and the spout, that is, the upper space of the main body covered by the lid is pressed toward the pressing portion. And a partition portion for dividing into a spout side is provided on one of the upper surface of the main body portion and the inside of the lid portion,
As described above, even with a simple configuration using a single partition portion, the pressing portion can be shielded from scattered droplets and the like scattered by the impact at the time of closing the lid.

According to a fifth aspect of the present invention, in the cap according to any one of the first to fourth aspects, the main body has a groove on the spout side of the partition. It is characterized by:

According to the fifth aspect of the present invention, when the liquid remaining in the vicinity of the spout flows down along the upper surface of the main body, it enters the groove provided on the spout side of the partition wall and is stored. Thereby, it is possible to prevent the residual liquid from being squeezed between the main body and the lid and scattered around the cap when the lid is closed.

[0023]

Embodiments of the present invention will be described below with reference to the drawings.

First Embodiment FIGS. 1 to 8 show a cap according to a first embodiment of the present invention. The cap 10 is a molded product made of a synthetic resin,
And a cylindrical cap body 16 attached to the opening 14 (FIG. 2). A female groove 18 is formed on the inner peripheral surface of the cap main body 16 and is screwed with a male groove 20 formed in the mouth portion 14 to seal the mouth portion 14.

On the upper surface of the cap body 16, a lid engaging step portion 24 is projected from the outer peripheral portion, leaving a hook portion 22. A cylindrical portion 26 is formed at the center of the lid engaging step portion 24. I have. A nozzle-like spout 28 projects obliquely upward from the cylindrical portion 26, and a pressing portion 30 is provided on the upper portion of the cylindrical portion 26.

Between the spout 28 and the pressing portion 30, a partition wall 40, which will be described later, is provided upright from the upper surface of the lid engaging step 24. Two grooves 23 are formed along the circumferential direction of the cap body 16.

As shown in FIG. 3, which is a sectional view from the side, the pressing portion 30 has a distal end portion 30 connected to the base side of the spout 28.
A is formed to be thinner than the cylindrical portion 26. The tip portion 30A is the thinnest (the thinnest portion O) on the base side of the spout 28, and is tapered to gradually increase the thickness from there, and the button portion 30B is formed into a substantially cylindrical shape with a predetermined thickness. Is connected to.

The rear end portion 30C of the pressing portion 30 connected to the cylindrical portion 26 has a stepped shape having a substantially stepped (substantially Z-shaped) shape in a sectional view. It is relatively thinner than the cylinder 26 and the button 30B.

As a result, the button portion 30B is moved in the direction indicated by the arrow P in the figure.
When pressed in the direction, as shown in FIG.
C is bent and deformed as shown, and the rear side sinks downward. The inside of the container is pressurized by the deformation of the pressing portion 30. At this time, if the container is inclined with the spout 28 facing downward, the seasoning moved to the cap 10 side will be discharged.
It is poured out from.

When the pressing force on the button portion 30B is reduced, the pressing portion 30 returns to the original state by the elastic force of the rear end portion 30C (FIG. 3), and the next pouring operation becomes possible. At this time, the seasoning accumulated in the spout 28 is
It is hard to drip because it is sucked back into 2.

Further, since the pressing portion 30 of the present embodiment is configured to sink the rear side downward as described above,
The operation fits the movement of the fingertip pressing the button portion 30B, the operability is good, and the rear end portion 30C has a thin step shape, so that the flexibility and the restorability are also good. further,
With the step shape, the displacement amount of the pressing portion 30 can be increased,
Since the amount of seasoning to be spouted by one pressing operation can be increased, it is suitable for spar oil obtained by performing an appropriate amount by several times of spouting operations. Here, the button portion 30B has a large diameter and is easy to press with a finger.

On the other hand, a pair of thin and elastically deformable hinges 32 are formed at predetermined intervals at the side end of the cap body 16 with the projecting side of the spout 28 facing the front (FIG. 1). 5), an elastic piece 38 described later is provided between the hinges 32. This hinge 32 has a disc-shaped lid 3
4 and the hinge 32 is disposed outside the lid 34, whereby the lid 34 is connected to the cap body 16 via the hinge 32 as shown in FIG. 6 or FIG.
Open (solid line in the figure) and close (double-dashed line in FIG. 7)
I can do it.

The lid 34 has an inner diameter slightly smaller than the diameter of the lid engaging step 24 so that the lid engaging step 2 can be closed when closed.
A flange 36 for hooking a finger at the time of opening / closing operation is protrudingly provided on the outer peripheral edge of the lid facing the hinge 32.

The above-described elastic piece 38 formed by cutting out a part of the lid 34 and the cap body 16 (between the hinges 32) is provided between the lid 34 and the cap body 16. The elastic piece 38 has a thin plate shape and a substantially middle portion in a longitudinal direction (opening / closing direction of the lid 34) is bent at a substantially right angle, and both ends are separated (or returned) and elastically deformed with the opening / closing operation of the lid 34. Thus, a biasing force is generated on the lid 34.

In this case, the substantially middle point of the operating range of the lid 34 is the position where the amount of deformation is maximized because both ends of the elastic piece 38 are separated, and the elastic piece 38 is moved in both directions with the middle point as a boundary. Both ends are gradually returned. Therefore, the lid 34 is held at that position in the open state (solid line position in FIG. 8), and is urged toward the cap main body 16 when it is covered with the cap main body 16 (two-dot chain line position in FIG. 8). Configuration.

Further, the inside of the lid 34 is shifted forward (the spout 28).
On the side), the auxiliary wall portion 4 slidably in contact with the wall surface of the partition wall portion 40 with the lid 34 covering the upper surface of the cap body 16.
2 are standing.

First, the partition 40 on the side of the cap body 16 will be described. The partition 40 is formed in a direction along the opening and closing direction of the lid 34 that operates via the hinge 32, and
The width of both sides of the cap main body 16 is approximately equal to the outer circumference of the lid engaging step 24 across the upper surface of the cap body 16.
Is completely closed, and has a height such that a small gap is formed between the cover 34 and the inner surface thereof.

On the other hand, an auxiliary wall portion 42 provided on the lid 34
Is formed in a direction along the opening / closing direction of the lid 34, that is, in a position parallel to the partition 40 and in sliding contact with the wall surface of the partition 40 at the pressing portion 30 side in a state where the lid 34 is closed. Both ends are connected to the peripheral wall of the lid 34 across the inside of the lid 34. At the center in the width direction, a rectangular notch 44 is formed as a relief for preventing the upper surface of the auxiliary wall portion 42 from hitting the cylindrical portion 26 when the lid 34 is closed,
The height of the walls located on both sides of the notch 44 is
Are completely closed so that there is a small gap between the cover engaging step 24 and the cover engaging step 24.

Next, the operation of the cap 10 according to the present embodiment will be described.

As shown in FIG. 7, the lid 34 of the cap 10
Is fitted into the lid engaging step portion 24 of the cap body 16 and is completely closed, the peripheral portion 34A of the lid 34 abuts on the hanging portion 22, and the upper surface of the cap body 16 is substantially sealed, and the spout 28 is closed by the wall surface 34B of the lid 34 to prevent liquid leakage.

In this state, since the auxiliary wall portion 42 provided inside the lid 34 is in sliding contact with the wall surface of the partition portion 40 erected on the upper surface of the cap body 16 on the pressing portion 30 side, the spout 28 The distal end is tightly sealed to the wall surface 34B.

The upper space of the cap body 16 covered by the lid 34 is divided by the partition wall portion 40 and the auxiliary wall portion 42 into the pressing portion 30 side and the spout 28 side. Here, if the residual liquid remaining in the vicinity of the tip of the spout 28 after the seasoning has been poured is scattered in the direction of the pressing portion 30 due to an impact at the time of closing the lid, the scattered drops are blocked by the partition wall portion 40 and the auxiliary wall portion 42. Then, it stays in the space on the spout 28 side. The container 12
Similarly, when the container 12 is shaken to stir the seasoning therein, the residual liquid that is about to flow into the pressing portion 30 from near the spout 28 is blocked by the partition wall portion 40 and the auxiliary wall portion 42.

Thus, the attachment of the seasoning to the pressing portion 30 is prevented, and the pressing portion 30 is not stained by the seasoning.

When the lid 34 is opened and closed via the hinge 32, the auxiliary wall portion 42 moves along the operating direction of the lid 34 which opens and closes with the hinge 32 as a fulcrum. Then, it comes into sliding contact with the partition wall portion 40 also formed along the opening and closing direction of the lid 34, and separates from the sliding contact state. Thereby, the frictional resistance between the partition 40 and the auxiliary wall 42 is reduced, the opening and closing operation of the lid 34 is smooth, and the adhesion between the partition 40 and the auxiliary wall 42 is also good.

When the lid is closed, the lid 34 is accelerated by the repulsive force of the elastic piece 38, so that the impact when the lid 34 comes into contact with the cap body 16 is large, so that the seasoning scatters violently. However, in the present embodiment, since the auxiliary wall portion 42 that moves with the opening and closing of the lid 34 slidably contacts the partition portion 40 before the lid 34 abuts on the cap body 16, the scattered droplets are It can be surely prevented from entering the side space.

When a load is applied to the hinge 32 due to, for example, being twisted in a state where the lid 34 is closed, a contact portion between the partition wall portion 40 and the auxiliary wall portion 42 generates a resisting force against the twisting force. The partition 40 and the auxiliary wall 42 have a large contact width (area) across the upper surface of the cap body 16 and the inside of the lid 34, thereby increasing the resistance to twisting. Therefore, the load applied to the hinge 32 is greatly reduced, and the hinge 32 is less likely to be damaged.

When a large amount of the seasoning remains in the vicinity of the spout 28, the remaining liquid flows downward along the upper surface of the cap body 16, and reaches the hanging portion 22, whereupon the remaining liquid flows to the spout 28 side of the partition 40. It enters the groove 23 located and is stored. For this reason, when the lid 34 is closed, the residual liquid is caught between the cap body 16 and the lid 34, thereby preventing the liquid from scattering around the cap 10.

In this embodiment, the auxiliary wall portion 42 is brought into contact with the wall surface of the partition portion 40 on the side of the pressing portion 30 so that the spout 2
Although the seal 8 is configured to be more reliable, the auxiliary wall portion 42 may be brought into contact with the wall surface on the spout 28 side. The configuration of the wall for preventing the seasoning from adhering to the pressing portion 30 may be, for example, abutting or fitting the upper surfaces of both walls in a closed state, in addition to sliding the wall as in the present embodiment. And so on.

Further, the number and the shape of the groove portions 23 are not limited to the present embodiment. For example, a groove may be formed on the entire periphery of the hook portion 22 in order to increase the volume of the groove.

[Second Embodiment] Next, a second embodiment of the present invention will be described. In this second embodiment,
Since the configuration is almost the same as that described in the first embodiment, the same components are denoted by the same reference numerals, and the description of the configuration will be omitted.

FIG. 9 is a sectional view showing a state where the cap according to the second embodiment of the present invention is attached to a container.

The cap 50 does not have the auxiliary wall portion 42 provided inside the lid 34 provided in the first embodiment. However, the partition wall portion 40 erected on the upper surface of the cap body 16 extends, and the cap 50 is closed as shown in the figure. In the lid state, the upper surface of the partition wall portion 40 comes into contact with the inner surface of the lid 34.

As a result, the upper space of the cap body 16 covered by the lid 34 is
Divided into sides and. Therefore, such a single partition 40
With the simple configuration described above, the pressing portion 30 can be shielded from scattered droplets and the like scattered from the vicinity of the spout 28 due to the impact at the time of closing the lid.

In this embodiment, the inner surface of the lid 34
By forming a groove or the like for fitting the upper part of the partition part 40, it is possible to prevent the hinge 32 from being damaged due to the twist of the lid 34.

The partition 40 may be provided only on the inside of the lid 34. In this case as well, the adhesion of the residual liquid scattered from the vicinity of the spout 28 to the pressing portion 30 can be prevented.

Further, the present invention can be applied to a cap having no hinge and having a structure in which a lid is detached from a cap body, and can also be applied to caps other than seasonings.

[0057]

Since the cap of the present invention has the above-described structure, it is possible to prevent the residual liquid scattered from the vicinity of the spout from adhering to the pressing portion and scattering around the cap due to an impact at the time of closing the lid.
