Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a container with a cap for containing a fluid, and more particularly to a container with a cap capable of discharging the fluid therein without removing the cap.

[0002]

[Prior art]

 A container for storing a fluid is usually provided with a cap at the inlet / outlet of the fluid, and when the fluid is discharged from the container, this cap is generally removed. In addition to this, it is also known that an opening / closing lid is hinge-coupled to a perforated cap so that a fluid can be poured out only by opening the opening / closing lid.

[0003]

[Problems to be solved by the device]

 It is troublesome to remove the cap to take out the fluid inside. In addition, the method of attaching the open / close lid to the cap is structurally complicated, resulting in high cost, and in many cases, the lid is an obstacle when pouring out the fluid.

An object of the present invention is to provide a container with a cap that can discharge the fluid inside by a simple operation without removing the cap and is structurally simple.

[0005]

[Means for Solving the Problems]

 A container with a cap according to the present invention comprises a container body, an inner cap, and an outer cap. The container body has an open cylindrical portion at the upper end, and an external thread portion on the outer peripheral surface of the open cylindrical portion. The inner cap has a lower cylindrical portion having an internal thread portion on the inner peripheral surface for screw-engaging with the male screw portion of the opening cylindrical portion, an intermediate cylindrical portion having a smaller diameter formed on the lower cylindrical portion, and an intermediate portion. The upper cap has a smaller diameter than that formed on the cylindrical portion, and has a flow hole at the step between the intermediate cylindrical portion and the upper protruding portion. A canopy portion having a hole that fits with the upper end projection, a first cylindrical portion that fits on the outer circumference of the intermediate cylindrical portion, and a second cylindrical portion that fits on the outer circumference of the lower cylindrical portion. And the outer cap is relative to the inner cap. It can be moved up and down, and when the outer cap is pushed down, the top end protrusion closes the canopy hole, and when the outer cap is pushed up, a gap is created between the top end protrusion and the canopy hole. The intermediate cylindrical portion and the first cylindrical portion are engaged with each other when the outer cap is pushed down and the upper end projection is in a position to close the hole of the canopy portion, and are fixed to the outer cap. It has an engaging part that prevents the outer cap from moving upward unless a pushing force exceeding the limit is applied, and the outer cap is pushed up to open the gap between the top projection and the hole in the canopy to a predetermined size. The outer caps have engaging portions that engage with each other when they are in the closed position and restrict the further movement of the outer cap upward.

[0006] Since this container with a cap has the above-described structure, when the outer cap is pushed up, a gap is formed between the upper end projection and the hole in the canopy, and the fluid inside is poured out. When the outer cap is pushed down, the top protrusion can block the hole in the canopy to prevent the fluid inside from flowing out.

[0007]

[Embodiment of device]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the figure, 11 is a container body, 13 is an inner cap, and 15 is an outer cap, all of which are made of plastic. 1 is a cross-sectional view of the outer cap 15 being pushed down, FIG. 2 is a cross-sectional view of the outer cap 15 being pushed up, and FIG. 3 is a cross-sectional view of the state immediately before pushing the outer cap 15 into the condition of FIG. FIG. 4 is a plan view with the outer cap 15 removed, and FIG. 5 is a perspective view of the entire capped container.

The container body 11 has an open cylindrical portion 17 at the upper end, which serves as an inlet / outlet for the fluid, and a male screw portion 19 is formed on the outer peripheral surface of the open cylindrical portion 17. The container body 11 has a general form.

Next, the inner cap 13 is formed on the lower cylindrical portion 23, which has an inner peripheral surface having a female threaded portion 21 that is screwed to the male threaded portion 19 of the opening cylindrical portion 17, and the lower cylindrical portion 23. It has an intermediate cylindrical portion 25 having a smaller diameter and an upper end protruding portion 27 formed on the intermediate cylindrical portion 25 and having a smaller diameter than that. A flow hole 29 that communicates the inside and the outside is formed in the step between the intermediate cylindrical portion 25 and the upper end protrusion 27. As shown in FIG. 4, the flow holes 29 are fan-shaped when viewed from above, and four flow holes 29 of the same size are formed in this example.

Next, the outer cap 15 has a canopy portion 33 having a hole 31 at the center for fitting with the upper end protrusion 27, and a first cylindrical portion 35 for fitting on the outer periphery of the intermediate cylindrical portion 25. It has a second cylindrical portion 37 fitted to the outer periphery of the lower cylindrical portion 23 and a third cylindrical portion 39 located outside thereof.

The inner cap 13 is screwed to the open cylindrical portion 17 of the container body 11 and normally is not removed from the container body 11. The outer cap 15 is vertically movable relative to the inner cap 13. In order to limit the moving range of the outer cap 15, the following structure is adopted.

That is, the annular protrusion 41 is formed on the outer peripheral surface of the intermediate cylindrical portion 25, and the annular groove 43 is formed on the inner peripheral surface of the first cylindrical portion 35. When the outer cap 15 is pushed down and the upper end projection 27 is in a position to close the hole 31 of the canopy portion (in the state of FIG. 1), the groove 43 engages with each other to move the outer cap 15 up and down. Block. Further, on the inner peripheral surface of the first cylindrical portion 35, an upper annular protrusion 45 is formed immediately below the annular groove 43, and a lower annular protrusion 47 is formed at a certain distance below the position. There is. The inner diameters of the upper annular protrusion 45 and the lower annular protrusion 47 are slightly smaller than the outer diameter of the annular protrusion 41 of the intermediate cylindrical portion 25, and the inner diameter of the section between the upper annular protrusion 45 and the lower annular protrusion 47 is intermediate. The annular protrusion 41 of the cylindrical portion 25 is slidable in the vertical direction, but has a size such that no gap is formed between the annular protrusion 41 and the annular protrusion 41.

In the state shown in FIG. 1, the outer cap 15 is pushed down to the bottom. In this state, since the annular protrusion 41 of the intermediate cylindrical portion 25 and the annular groove 43 of the first cylindrical portion 35 are engaged with each other, the outer cap 15 does not move in the vertical direction. Further, since the upper end projection 27 covers the hole 31 of the canopy 33, the fluid contained in the container body 11 does not flow out.

In the state shown in FIG. 1, when the outer cap 15 is pushed up (pulled upward) with a force equal to or greater than a certain limit, the upper annular protrusion 45 on the inner surface of the first cylindrical portion 35 is elastically deformed and the upper annular protrusion 45 is deformed. Overcome the annular protrusion 41 on the outer surface. Then, when the outer cap 15 is further pushed up (a small pushing force is sufficient at this time), the state shown in FIG. 2 is obtained. In this state, the lower annular protrusion 47 on the inner surface of the first cylindrical portion 35 is caught by the annular protrusion 41 on the outer surface of the intermediate cylindrical portion 25, so that the outer cap 15 cannot move any further. In this state, since a gap is formed between the upper end protrusion 27 and the hole 31 of the canopy, the fluid in the container body 11 flows out to the outside through the flow hole 29 of the inner cap 13 and the gap. Can be made.

Next, when the external cap 15 is pushed down from the state shown in FIG. 2 with a small force, the state shown in FIG. 3 is obtained. In this state, since the upper annular protrusion 45 on the inner surface of the first cylindrical portion 35 is caught by the annular protrusion 41 on the outer surface of the intermediate cylindrical portion 25, the outer cap 15 cannot be pushed down further. Here, when a strong pushing-down force exceeding a certain limit is applied to the outer cap 15, the upper annular protrusion 45 on the inner surface of the first cylindrical portion 35 rides over the annular protrusion 41 on the outer surface of the intermediate cylindrical portion 25 due to elastic deformation. Return to.

In addition, in the state of FIG. 2, when the outer cap 15 is pushed up by a force exceeding a certain limit, the lower annular protrusion 47 on the inner surface of the first cylindrical portion 35 is elastically deformed and the annular protrusion 41 on the outer surface of the intermediate cylindrical portion 25 is elastically deformed. The outer cap 15 can be removed from the inner cap 13 in order to get over. Such removal is not performed under normal use.

By the way, the upper end projection portion 27 of the inner cap 13 and the hole 31 of the canopy portion 33 are fitted with a tapered surface whose diameter becomes smaller as it goes upward. This is to reliably prevent leakage of the fluid when the hole 31 is closed by the upper end protrusion 27 (the state shown in FIG. 1).

Further, on the outer peripheral surface of the third cylindrical portion 39 of the outer cap 15, a circumferential concave line 49 (may be a convex line) is formed. This is to prevent fingers from slipping when pushing up the outer cap 15.

A projecting edge 51 is formed on the outer peripheral portion of the upper surface of the canopy portion 33 of the outer cap 15. The projecting edge 51 functions as a weir that prevents the fluid flowing out from the hole 31 and then flowing out to the upper surface of the canopy portion 33 from dropping further to the outer peripheral surface of the outer cap 15. .

A plurality of grooves 53 are formed in the vertical direction on the outer peripheral surface of the lower cylindrical portion 23 of the inner cap 13, and the vertical direction is formed on the inner peripheral surface of the second cylindrical portion 37 of the outer cap 15. Ribs (not shown) that enter the grooves 53 are formed. Due to the engagement of the groove 53 and the rib, the inner cap 13 and the outer cap 15 are prevented from relatively rotating in the circumferential direction. That is, when the outer cap 15 is rotated, the inner cap 15 is also rotated. It can be combined and removed.

Further, as shown in FIG. 5, the outer cap 15 may be provided with a mark 55 indicating that the outer cap 15 is pushed up and used.

The above is one embodiment of the present invention, and the present invention is not limited to this. For example, the engagement portion between the intermediate cylindrical portion that regulates the vertical movement range of the outer cap and the first cylindrical portion can be reversed in the concavo-convex relationship. Also, the third cylindrical portion of the outer cap can be omitted.

[0023]

[Effect of device]

 As described above, the capped container according to the present invention allows the fluid in the container body to flow out or not to flow out only by pushing up or down the outer cap. It is extremely easy to open and close. In addition, since the structure other than the container body is a two-part structure including an inner cap and an outer cap, it is structurally simple and cost reduction can be achieved.
