(Solution means) A hole 54 is formed in the bottom of the inner cap 24, and the slide cap 20 and the container 14 communicate with each other through the hole 54. Therefore, the air and the fluid 12 in the container 14 pass through the hole part 54 only by the operation which presses the container 14, and the slide cap 20 is moved upward along the axial direction of the inner cap 24. Slide it. In addition, since the communication port 34 formed in the inner cap 24 is located above the discharge port 52 in the state where the slide cap 20 is pulled down, the discharge port 52 is made by sliding the slide cap 20 upward. And the communication port 34 communicate with each other, the fluid 12 flowing through the communication port 34 is discharged from the discharge port 52. With the above configuration, the fluid can be discharged by one operation for pressing the container 14.

Description

Cap {Cap}

The present invention relates to a cap for use in a container filled with a fluid.

An opening / closing cap 70 is attached to the upper portion of the soft container filled with the fluid (for example, ketchup) as shown in FIG. 6. When the cover 72 of this cap 70 is opened and the container not shown in figure is pressed, the fluid filled in the inside of the container is discharged from the discharge port 78 formed in the cap 70.

As described above, in order to discharge the fluid from the container, since the cover 72 of the cap 70 is opened, two operations of pressing the container and discharging the fluid from the container are necessary, the operation is complicated and cumbersome. .

In addition, a spring hinge 80 is formed in the cap 70, and the cover 72 is held toward the discharge port 78 by the spring hinge 80, but the adhesion force between the boss 82 and the discharge port 78 is maintained. If this falls, there is a possibility that the fluid flows out when the container is upside down.

In view of the above-described facts, it is an object of the present invention to obtain a cap capable of discharging the fluid by one operation and without causing the fluid to flow out even when the container is upside down.

In the present invention, a cylindrical inner cap can be engaged with the opening of the soft container filled with the fluid. A communication port is formed in this inner cap, and the fluid flowing out from the opening can flow.

On the other hand, the opening and closing means is formed with a discharge port capable of discharging the fluid, pressurize the container to increase the internal pressure is pushed up from the inner cap to communicate with the communication port and the discharge port, and pulled toward the inner cap to block the communication port.

In this way, when the container is pressed and the internal pressure is increased, the communication port and the discharge port communicate with each other, so that the fluid in the container is discharged only by pressing the container. Therefore, it is possible to discharge the fluid by one operation. In addition, since the communication port and the discharge port are not communicated unless the internal pressure of the container is increased, the fluid does not flow out even when the container is upside down.

A slide cap is attached to the inner cap from the outside, and the inner cap is slidable in the axial direction of the inner cap. On the other hand, the upper surface of the inner cap is provided with a hole for communicating the slide cap and the container.

Thus, by forming the hole part which communicates a slide cap and a container in the upper surface of an inner cap, air and a fluid in a container push up the back surface of a slide cap through a hole part only by the operation which presses a container, The upper side is slidable along the axial direction of the inner cap.

Moreover, the sealing member which seals around the communication port in the state which pulled down the inner cap is provided between the inner cap and the slide cap. Since the communication port is sealed in this way, there is no fear that various germs will propagate. Moreover, since the sealing member is provided between the inner cap and the slide cap, the fluid flowing out of the communication port does not invade between the inner cap and the slide cap.

On the other hand, the sealing member is an O-ring and is disposed around the communication port. In this way, when the O-ring is used as the sealing member, the contact area with the slide cap is smaller than when the flat packing is used, and thus the slide resistance at the time of sliding the slide cap becomes small.

Then, a blocking means for closing the discharge port is formed while the slide cap is pulled down. Therefore, when not in use, since the discharge port is blocked by the blocking means, it is hygienically stable.

Moreover, the inner side cap is provided with the elastic piece which can be elastically deformed to stand in the direction to which a slide cap slides. A stopper portion is formed on the free end side of the elastic piece. The stopper portion is engaged with the discharge port in a state where the communication port is closed, and the engagement state is released when the slide cap slides upward.

In this way, since the engagement state of the discharge port and the stopper is released only by pressing the container, it is not necessary to remove the stopper from the discharge port. Moreover, it is very convenient because not only the fluid in the container is discharged by the operation of pressing the container but also the release state and the stopper can be engaged.

In addition, the engaging portion protrudes from the inner circumferential surface of the slide cap. On the other hand, the engaging portion is formed on the outer circumferential surface of the inner cap, and is engaged with the engaging portion formed in the slide cap when the communication port is closed and when the communication port and the discharge port communicate with each other to position the slide cap.

In this way, by engaging the engaging portion and the engaged portion, it is possible to distinguish when the communication port is blocked and when the communication port and the discharge port communicate with each other. In addition, since the slide cap is positioned when the communication port and the discharge port communicate with each other, the slide cap does not come out of the inner cap.

Embodiment of the Invention

1-5, the cap 10 which concerns on this embodiment is shown. The cap 10 is attached to the opening 15 of the container 14 filled with a fluid 12 such as ketchup. The container 14 is made of a soft material, and is easily collapsed when pressed by hand.

The cap 10 is composed of a slide cap 20, an outer cap 22 and an inner cap 24, and each has a substantially cylindrical shape. The slide cap 20 and the outer cap 22 are attached to the inner cap 24 from the outside.

On the proximal end side of the inner cap 24, a large diameter portion 26 having a female threaded portion 26A is formed. The inner cap 24 is attached to the opening portion 15 by screwing the female screw portion 26A into the male screw portion 15A formed in the opening portion 15 of the container 14.

Moreover, the hole part 54 is formed in the bottom face of the inner cap 24. As shown in FIG. The slide cap 20 attached to the inner cap 24 and the container 14 communicate with each other through the hole portion 54.

Therefore, since only air and the fluid 12 in the container 14 push the bottom surface of the slide cap 20 through the hole 54 by the operation of pressing the container 14, the slide cap 20 It slides to the upper side (arrow A direction) along the axial direction of this inner cap 24 (refer FIG. 4).

The small diameter part 28 is formed in the front-end | tip part side of the said inner cap 24, The communication hole 34 which the fluid 12 can flow is penetrated by the outer peripheral surface of this small diameter part 28. As shown in FIG. Ring-shaped O-ring accommodating portions 30 and 32 are formed concave up and down the communication port 34.

O-rings 35 as sealing members are accommodated in the O-ring accommodating parts 30 and 32, respectively, and the inner circumferential surface of the slide cap 20 slides. Therefore, the sealing body is secured by preventing the fluid 12 flowing out of the communication port 34 from invading between the inner cap 24 and the slide cap 20.

In addition, when the O-ring 35 is used as the sealing member, the contact area with the slide cap 20 is smaller than when the flat packing is used, so that the slide resistance at the time of sliding the slide cap 20 becomes smaller. do. In addition, the o-ring 35 is formed of a material having a small coefficient of friction, and further reduces the slide resistance when the slide cap 20 slides.

On the other hand, on the proximal end side of the small diameter portion 28, a plurality of annular engaging portions 38 are formed on the outer peripheral surface thereof. The engaging portion 38 includes the engaging portion 40 for the outer cap to which the outer cap 22 is engaged, the closing engaging portion 42 for the slide cap 20 to be engaged, and the opening portion. It is divided into the engaging part 44, and is arrange | positioned sequentially from the base end side of the small diameter part 28. As shown in FIG.

An engagement portion 20A protrudes toward the axial center side at the periphery of the slide cap 20. Moreover, the slit which is not shown in figure is formed in the periphery part of the slide cap 20, and by this it becomes possible for the slide cap 20 to spread outward, so that it can attach to the inner cap 24 from the outer side. do.

When the slide cap 20 is mounted on the outer side of the inner cap 24, the slide cap 20 is elastically restored so that the closing engagement portion 42 with the engaging portion 20A formed on the inner cap 24 is provided. And the opening engagement portion 44 for opening.

Therefore, as shown in Fig. 2, when the engaging portion 20A is engaged with the closing engagement portion 42 so that the slide cap 20 is positioned, the communication port 34 is in a closed state. do. As shown in Fig. 4, when the engaging portion 20A is engaged with the opening engaging portion 44 and the slide cap 20 is positioned, the communication port 34 and the discharge port 52 are formed. Is in a connected state.

In this way, by engaging the engagement portion 20A, the closing engagement portion 34 and the opening engagement portion 44, respectively, the communication opening 34 and the communication opening 34 are closed. And when the discharge port 52 communicates with each other are distinguished.

Here, the closing engagement portion 42 is smaller in the amount of protrusion from the outer circumferential surface of the inner cap 24 than the opening engagement portion 44 for opening. Therefore, when the container 14 is pressed and the internal pressure is increased, since the engagement part 20A of the slide cap 20 can ride over the closing engagement part 42, as shown in FIG. The cap 20 can be pushed up along the axial direction of the inner cap 24.

And as shown in FIG. 4, when the engagement part 20A of the slide cap 20 is engaged with the opening engagement part 44 for opening, the movement of the slide cap 20 is regulated. Therefore, the slide cap 20 does not fall out of the inner cap 24 at the time of use.

On the other hand, a discharge port 52 protrudes from the outer circumferential surface of the slide cap 20. Therefore, when discharging the fluid 12 from the discharge port 52, the fluid 12 does not adhere to the outer circumferential wall of the slide cap 20. Moreover, since the discharge port 52 protrudes from the outer peripheral wall of the slide cap 20, the fluid 12 falls out well and the fluid 12 does not flow in the slide cap 20. As shown in FIG.

Here, as shown in FIG. 2, since the communication port 34 formed in the inner cap 24 is located above the discharge port 52 in the state where the slide cap 20 is pulled down, the slide cap 20 is positioned upward. The discharge port 52 and the communication port 34 communicate with each other by sliding in the (arrow A direction) (see FIG. 4). Therefore, the fluid 12 flowing through the communication port 34 is discharged from the discharge port 52.

According to the configuration as described above, the air and the fluid 12 in the container 14 pushes the bottom surface of the slide cap 20 through the hole 54 only by pressing the container 14, That is, the communication port 34 and the discharge port 52 can communicate with each other by sliding the slide cap 20 along the axial direction of the inner cap 24 (arrow A direction).

Therefore, the fluid can be discharged by one operation for pressing the container 14. In addition, since the communication port 34 and the discharge port 52 do not communicate in the state where the slide cap 20 is pulled down, even if the container 14 is upside down, the fluid 12 does not flow out.

In addition, since the communication port 34 is sealed by the O-ring 35 in the state where the slide cap 20 is pulled down, there is no fear of propagation of various germs and it is hygienic and safe.

On the other hand, a mounting hole 23 is formed in the bottom of the outer cap 22. Moreover, the slit which is not shown in figure is formed in the outer cap 22 along the axial direction, and it becomes possible for the outer cap 22 to spread out by this slit, and it attaches to the inner cap 24 from the outer side. It becomes possible.

When the outer cap 22 is mounted on the inner cap 24 from the outside, the outer cap 22 is elastically restored so that the edge portion of the mounting hole 23 formed in the outer cap 22 is engaged with the outer cap fitting portion 40. Will be caught up in

Moreover, the rectangular receiving part 46 continuous to this bottom face is formed in the bottom face of the outer cap 22 by protrusion. A rib 46A continuous to the outer circumferential wall 22A is formed at the edge portion of the receiving portion 46 in the width direction, and the receiving portion 46 is reinforced.

An elastically deformable elastic piece 48 which is erected in the direction in which the slide cap 20 slides is formed at the tip end of the receiving part 46. An arc shaped stopper 50 protrudes from the distal end of the elastic piece 48 toward the shaft center side of the outer cap 22. The tip portion of the discharge port 52 formed in the slide cap 20 is closed by the plug portion 50.

Here, the hole diameter of the discharge port 52 is smaller than the stopper 50 of the elastic piece 48 formed in the outer cap 22, and the front end of the stopper 50 can be engaged. Therefore, as shown in FIG. 3, when the slide cap 20 slides (when the container 14 is pressed), the hole edge part of the discharge port 52 is along the shape of the stopper 50, and the elastic piece 48 is carried out. ) Elastically deforms outward, the plug portion 50 is easily removed from the discharge port (52).

Therefore, it is not necessary to pull out the plug part 50 from the discharge port 52 by hand. In addition, when not in use, as shown in FIG. 2, since the discharge port 52 is closed by the plug part 50, it is sanitary safe.

Thus, since the engagement state of the discharge port 52 and the plug part 50 is released only by the operation which presses the container 14, it is not necessary to remove the plug part 50 from the discharge port 52. FIG. In addition, the fluid 12 in the container 14 is not only discharged by the operation of pressing the container 14, but also the release state of the discharge port 52 and the stopper 50 can be released. It is convenient.

On the other hand, when the discharge port 52 of the slide cap 20 abuts against the stopper 50 as shown in FIG. 3 by pulling down the slide cap 20 shown in FIG. 5, the outer circumferential surface of the discharge port 52 The elastic piece 48 is elastically deformed outward.

As shown in FIG. 2, when the engagement portion 20A of the slide cap 20 is engaged with the closing engagement portion 42, the elastic piece 48 is elastically restored and the stopper portion ( The discharge port 52 is blocked by engaging 50 at the distal end of the discharge port 52.

In this way, the stopper 50 is engaged with the distal end of the discharge port 52 only by the operation of pulling down the slide cap 20 so that the discharge port 52 is closed. At this time, the discharge port 52 communicating with the communication port 34 moves downward, so that the communication port 34 is closed by the inner circumferential wall of the slide cap 20.

On the other hand, as shown in FIG. 5, when the force for pressing the container 14 is released, the pressure in the container 14 decreases, so that the fluid 12 near the discharge port 52 passes through the communication port 34. (14) will be sucked into. Therefore, the fluid 12 does not remain near the discharge port 52.

Moreover, the upper surface of the inner cap 24 is made into the inclined surface 24A which made the height of the side of the hole part 54 lower than the peripheral part. In this way, the fluid 12 penetrating between the inner cap 24 and the slide cap 20 easily moves toward the hole 54 (arrow direction shown in FIG. 5) when discharging the fluid 12. . Therefore, when the pressure in the container 14 is lowered, the fluid 12 located on the inclined surface 24A is easily sucked into the container 14 through the hole 54.

Moreover, the shaft part 56 is formed in the center of the bottom face of the slide cap 20, and can penetrate the hole part 54 formed in the upper surface of the inner cap 24. As shown in FIG. Further, an inclined surface 20B having an inclined angle substantially the same as that of the inclined surface 24A is formed on the bottom of the slide cap 20. In this way, when the fluid 12 is discharged, the fluid 12 penetrated between the inner cap 24 and the slide cap 20 is easily moved into the container 14 by the shaft 56. Therefore, when the pressure in the container 14 is lowered, the fluid 12 located on the inclined surface 20B is easily sucked into the container 14 by riding on the shaft portion 56.

In addition, when the engaging portion 20A of the slide cap 20 is engaged with the closing engagement portion 42 of the inner cap 24, the inclined surface 20B abuts against the inclined surface 24A and the slide cap The fluid 12 does not remain between the 20 and the inner cap 24.

In addition, in this embodiment, the slit was formed in the slide cap 20 and the outer cap 22 so that it could be attached to the inner cap 24 from the outside, but only if the slide cap and the outer cap are attached to an inner cap As it becomes, it is not limited to this.

Since the present invention has the above-described configuration, when the container is pressed and the internal pressure is increased, the communication port and the discharge port communicate with each other, so that the fluid in the container is discharged only by pressing the container. Therefore, it is possible to discharge the fluid by one operation. In addition, since the communication port and the discharge port are not communicated unless the internal pressure of the container is increased, the fluid does not flow out even when the container is upside down.

In addition, since the air and the fluid in the container push up the back surface of the slide cap by the operation of pressing the container only, the slide cap can slide upward along the axial direction of the inner cap.

And since the communication port is sealed, there is no possibility that various germs will propagate. Moreover, since the sealing member is provided between the inner cap and the slide cap, the fluid flowing out of the communication port does not invade between the inner cap and the slide cap.

On the other hand, since the contact area with a slide cap becomes small compared with the case where flat packing is used, the slide resistance at the time of sliding a slide cap becomes small.

Moreover, when not in use, the discharge port is blocked by the blocking means, so that it is stable in hygiene.

And since the engagement state of a discharge port and a stopper part is released only by the operation which presses a container, it is not necessary to remove a stopper part from a discharge port. Moreover, it is very convenient because not only the fluid in the container is discharged by the operation of pressing the container but also the release state and the stopper can be engaged.

In addition, the position of the slide cap can be determined when the slide cap is pulled down, and the slide cap does not come out of the inner cap when the slide cap is pushed up from the inner cap.
