Description

[Detailed description of the device] [The purpose of the device]

[0001]

[Industrial applications]

 The present invention provides a floating bag, a beach ball, a floating boat (hereinafter referred to as floating bags) used for sea bathing or the like (hereinafter referred to as floating bags) that can be evacuated very easily.

[0002]

[Prior art]

 Conventionally, floating bags have been provided with an air vent hole and an air vent hole having a structure as shown in FIG. Reference numeral 1 is a stopper, 2 is a check valve, and 3 is a cylindrical portion in which the stoppers fit. When air is introduced, the air flows in the direction of the arrow, and the check valve 2 is bent downward in Fig. 1 so that the air can easily flow in. However, when bleeding air, the air flows in the direction opposite to the arrow, so the check valve 2 is pushed upward and sticks to the end of the cylinder to close the opening, making it difficult for air to escape. There is. For this reason, when injecting air, it can be smoothly infused, but when deaerating, this check valve hinders the inconvenience that it cannot be easily inflated.

[0003]

[Problems to be solved by the device]

 Therefore, the conventional floating bags have a drawback that a considerable amount of labor and time are required for deaeration. Especially, large floating bags had this drawback.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned drawbacks, according to the present invention, as shown in Fig. 2, a plug for air venting having a large diameter and having a shape to fit from the inside to the outside of the floating bag is provided, or the outside of the floating bag shown in Fig. 3 is provided. Use a means such as installing a cap for air bleeding that has a large diameter and is fitted by rotating it from the.

[0005]

[Action]

 The stoppers shown in Figs. 2 and 3 for exclusive use of air release do not have a check valve and the diameter of the flow path for air outflow is large, so that air can be released very easily.

[0006]

[First Embodiment] In order to solve the above problems, there is also a method of increasing the diameter of a conventional plug for a floating bag. However, simply increasing the pressure increases the pressure applied to the stopper and may cause it to come off during use. In the present embodiment, as shown in FIG. 2, a description will be given of a floating bag having a structure for plugging from the inner side to the outer side and having a dedicated plug for air venting. FIG. 4 shows a more detailed sectional view of the portion 4 in FIG. Figure 4 shows the plugged state. The air vent plug of this embodiment has basically the same structure as the air vent plug, and is composed of a plug 8, a cylindrical portion 6 that fits into this plug, and a joint 7 that attaches the plug to a floating bag. I can do things.

When air is to be put into the floating bags, it is necessary to first insert a stopper from the inside to form an airtight state. However, the shape of the floating bags is not constant in a state where no air is contained, and can be freely used like a cloth. Since it is bent, the stopper 8 can be easily handled and applied together with the outer skin 11. When removing the air, it is sufficient to push down the stopper 8 with a finger or the like in the direction of the arrow in FIG. In this case, it is necessary to push down the stopper with a finger or the like, and the diameter of the stopper must be increased to some extent to release air in a short time.

The diameter of the conventional air-injecting / air-releasing plug is usually about 5 mm, and since the check valve is provided, the diameter of the air flow path in the case of air bleeding is considered to be equivalently about 3 mm. . Therefore, when the diameter of the air vent plug according to the present invention is about 2 to 3 cm, air can be vented several tens of times faster than before.

Further, since this air vent plug has a structure which can be removed by pushing it from the outside, there is a possibility that an object may hit from the outside during use by putting air into it, or it may come off due to a person's hand hitting. Therefore, it is convenient to provide fitting portions 9 and 10 between the stopper and the cylindrical portion so as not to come off easily. The mating portions 9 and 10 can be composed of a convex portion and a concave portion as shown in FIG.

[00010]

[Embodiment 2] In this embodiment, an example will be described in which a rotary type air-depleting stopper used for a lid of a bottle or a PET bottle is used. FIG. 3 shows a cross-sectional view of the present embodiment with the air vent plug attached. FIG. 3 shows a state in which the rotary plug 21 is fitted into the cylindrical portion 23 of the floating bag via the screw portion 22. Numeral 27 is a seal ring made of rubber or the like for creating a better confidential state. Since the air vent plug of this method can be removed by rotating it, it may be lost, so it is convenient to provide a connection 26 with a floating bag. Since this joint 26 rotates the stopper, it is preferable to make the neck portion of the protrusion 28 of the stopper 21 thin so that it is connected even in the rotating state, and to insert the neck portion into this portion.

In the case of this system, since the stopper is located outside the floating bags, the shape as shown in FIG. 3 may be an obstacle. Therefore, it is convenient to have a structure in which when the whole body is pushed in, it can be fitted into a floating bag and stored like a conventional stopper for inflating air. That is, it is convenient to provide the bent portion 24 near the stopper and push the entire air vent stopper into a shape as shown in FIG.

Also in the case of this system, it is preferable that the plug has a certain diameter as in the first embodiment in consideration of the ease of operation and the ease with which air is released.

Further, although FIGS. 3 and 5 show an example of the structure in which the plug 21 is fitted inside the cylindrical portion 23, it can be realized by a structure fitted inside the cylindrical portion.

[0014]

[Effect of device]

 The floating bags according to the present invention can remove air in a very short time.
