Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container provided with an air pump used for filling an inflatable body such as an air pillow or a floating bag with air.

[0002]

[Prior art]

 In the past, hollow inflatable bodies such as air pillows and floating bags were inflated by blowing them directly into the mouth.However, playground equipment consisting of large inflatable bodies have recently appeared, and for example, bellows-shaped or bellows-shaped Air pumps are used.

However, there is a problem that the conventional air pump is inconvenient to carry because it is bulky.

[0004]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that the conventional air pump for inflating a hollow inflatable body such as an air pillow or a floating bag is inconvenient to carry.

[0005]

[Means for Solving the Problems]

 According to the present invention, a bottomed tubular outer container body and a bottomed tubular inner container body are slidably and removably fitted in close contact with each other, and at least one of the container bodies is inserted. An object of the present invention is to provide a container that can be used as an air pump, characterized by being provided with a suction port and a discharge port.

[0006]

[Action]

 A hollow portion formed by inserting a bottomed tubular outer container body and a bottomed tubular inner container body forming the container into each other is defined as a container housing part.

Further, when the outer container body and the inner container body, which are fitted to each other, are reciprocally slid, and when the hollow portion formed by the outer container body and the inner container body extends, air is introduced from the suction port to the hollow portion. When introduced, when the hollow portion contracts, the pressure in the hollow portion rises and air is discharged from the discharge port.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIGS. 1 to 4 show an embodiment of the present invention. The container 1 shown in FIG. 1 is mainly a bottomed cylindrical outer container body 2 and a state in which the outer container body 2 is in close contact with the outer container body 2. And a bottomed cylindrical inner container body 3 which is slidably and detachably fitted.

The outer container body 2 and the inner container body 3 are made of, for example, synthetic resin having an appropriate thickness, and a suction port 4 and a discharge port 5 are formed on the bottom surface 21 of the outer container body 2, respectively. A check valve 41 that can be opened toward the inside is fitted in, and a discharge nozzle 51 that is formed separately can be fitted in the discharge port 5.

In the present embodiment, as shown in FIG. 2, the outer container body 2 and the inner container body 3 are used as containers in a state where they are fitted into each other, and the hollow portion 6 formed by both container bodies 2 and 3 is, for example, An air pillow or the like inflated by the air pump 1 or other items such as clothes and towels are stored and carried.

To use as an air pump, with the hollow portion 6 emptied, the discharge nozzle 51 is fitted into the discharge port 5 as shown in FIG. 3 and FIG. The container body 2 and the inner container body 3 are grasped and slid back and forth to repeatedly expand and contract.

At this time, when the length of the hollow portion 6 formed by the outer container body 2 and the inner container body 3 is extended, the check valve 41 fitted in the suction port 4 is opened and the air is blown into the hollow portion 6 When the length of the hollow portion 6 is shortened, the check valve 41 closes, the pressure inside the hollow portion 6 rises, and air is discharged from the discharge nozzle 51 through the discharge port 5.

As described above, this embodiment can be usually used as a container, can function as an air pump when necessary, and it is not necessary to carry an air pump separately, which is extremely convenient and bulky. Nor. It is also extremely advantageous in terms of resource conservation.

FIG. 5 shows another embodiment of the present invention, in which the overall structure and operation and effect are substantially the same as those of the above-mentioned embodiment, but the outer container body 2 and the inner container body 3 have a bottom surface 21. , 31 on the same side, and further has an annular locking projection 71 for detachably locking the annular locking projection 22 formed on the outer peripheral surface of the outer container body 2. The lid body 7 is detachably fitted to the open end 32 of the inner container body 3.

In addition, the present embodiment having such a configuration is different from the above-mentioned embodiment in that the long outer container body 2 is not pulled out, and the short lid body 7 is simply opened and closed to be housed in the hollow portion 6. It also has the advantage that it can be put in and taken out, which is extremely convenient.

In the above embodiment, the outer container body 2 and the inner container body 3 are cylindrical bodies having elliptical bottom surfaces 21 and 31, but it is needless to say that they may have other shapes.

Further, in the above-described embodiment, the suction port 4 and the discharge port 5 are provided on the bottom surface 21 of the outer container body 2. However, the suction port 4 and the suction port 5 are provided in the inner container body 1 or the outer container body 2. It may be provided in any of them, and the number thereof is not limited. Further, although the discharge nozzle 51 is provided as a separate body in the above-mentioned embodiment, the discharge port 5 may be directly provided with the nozzle integrally.

Further, in the above-mentioned embodiment, since the check valve 41 is fitted in the suction port 4, the inner container 1 and the outer container body 2 can be slid back and forth, and the expansion and contraction can be simply repeated. Compressed air can be discharged from the discharge port 5, but it is not always necessary to provide the check valve 41 in the suction port 4. In this case, the hollow portion 6 is extended with the suction port 4 opened, and the suction port 4 is expanded. 4 may be closed by, for example, a finger to shrink it. Particularly, when used for an inflatable body such as a balloon that needs to be filled with compressed air, it is preferable to provide a check valve at the discharge port 5.

Furthermore, the container 1 shown in the above-mentioned embodiment is made by fitting the inner container body 2 and the outer container body 3 from the beginning, but as shown in FIG. The parts 8 1 and 91 are formed so that they can be fitted closely and slidably, for example, a container 8 filled with shampoo and a container 9 filled with a rinse 9, which are filled with products in advance. 8, the inner container body 1 and the outer container body 2 are formed by cutting the containers 8 and 9 along the cutting lines 82, 92 formed on the containers 8 and 9 after the filling material of FIG. As shown in Fig. 5, for example, a container 8 filled with mineral water or the like is formed by being divided into upper and lower parts in a shape that can be slidably and pushably fitted in close contact with each other in the vicinity of the center in the height direction. Every other, along the dividing line 83 Alternatively, the inner container body 2 and the outer container body 3 may be cut to form the inner container body 2 and the outer container body 3. In addition, the suction port 4 and the discharge port 5 do not need to be provided from the beginning, and may be formed, for example, by cutting when used. May be.

Although all of the above-described embodiments have been described as being used as a discharge type air pump, it goes without saying that they can also be used as a suction pump, for example, for a vacuum pack.

[Effect of device]

 According to the present invention, it has a shape and function as a container having a hollow portion formed by inserting a bottomed cylindrical outer container body and a bottomed cylindrical inner container body into each other, as a container. Since it has a function as an air pump as it is, it is not necessary to carry an air pump separately as in the conventional case, and the baggage does not become bulky.

In addition, the structure is not complicated, the manufacturing is easy, and it can be provided at a low cost, which is advantageous in terms of economy and resource saving, and is also excellent in durability.
