【Example】

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

FIG. 1 shows an embodiment of the present invention, in which a container 1 is mainly detachably fitted into a container body 2 having a cylindrical shape with a bottom and an opening portion 21 of the container body 2. It is composed of a short bottomed cylindrical lid body 3.

The side surface 22 of the container body 2 is formed in a bellows shape and is capable of expanding and contracting in the length direction. In particular, in this embodiment, for example, an elastic synthetic resin material is used to release the external pressure from the state of being contracted by the external pressure. When it is done, it is formed so that it can automatically return to its original stretched state.

Also, A suction port 4 and a discharge port 5 are formed on the bottom surface 23 of the container body 2, and a check valve 41 that can be opened inward is fitted to the suction port 4 and the discharge port 5 is a separate body. The formed discharge nozzle 51 can be fitted.

The present embodiment can be used as a container by opening and closing the lid body 3. For example, an item such as an air pillow inflated by an air pump or other clothes or towels can be contained and carried. it can.

To use as an air pump, the open portion 21 is closed with the hollow portion 6 emptied, the discharge nozzle 51 is fitted into the discharge port 5, and a longitudinal pressing force is intermittently applied to the container body 2. It suffices to say that when a pressing force is applied and the container body 2 contracts, the check valve 41 closes, the internal pressure rises, air is discharged from the discharge nozzle 51 through the discharge port 5, and the pressing force is released. At this time, the side surface 22 of the container body 2 is automatically returned to the original stretched state, the check valve 41 is opened, and air is introduced into the inside. These operations are repeated, and the air is intermittently discharged from the discharge nozzle 51. Is discharged. Particularly, when used for an inflatable body such as a balloon which needs to be filled with compressed air, a check valve may be provided at the discharge port 5.

As described above, this embodiment can be normally used as a container, but it can function as an air pump when necessary, and is extremely convenient because it does not require carrying an air pump separately. Is not bulky and is advantageous in terms of resource saving.

In this embodiment, the side surface 22 of the container body 2 is made of a synthetic resin material having elasticity, so that the manufacturing is extremely easy. However, for example, a coil-like elastic spring is interposed in the bellows portion. In that case, there is an advantage that a larger restoring force can be obtained and a quick pump operation can be performed, and the elastic material is not necessarily used.

Further, in the above-described embodiment, the suction port 4 and the discharge port 5 are provided on the bottom surface 23 of the container body 2. However, the suction port 4 and the discharge port 5 are provided on either the container body 2 or the lid body 3. The discharge nozzle 5 may be provided independently of the installation position and the number thereof, but in the above-described embodiment, the discharge nozzle 5 is provided as a separate body, but the discharge port 5 may be directly provided with the nozzle 51 integrally. Good.

Further, in the above-described embodiment, since the check valve 41 is fitted in the suction port 4, the discharge port 5 can be easily operated by simply pressing the side surface 22 of the container body 2 and releasing it. Although compressed air can be discharged from the suction port 4, it is not always necessary to provide the check valve 41 at the suction port 4. In this case, the suction port 4 is opened by closing it with a finger or the like. The pressing force may be released in this state. Further, 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.

FIG. 2 shows another embodiment of the present invention, and the overall configuration and operation and effect are almost the same as the above-mentioned embodiment, but the side surface 22 of the container body 2 is not bellows-like and has elasticity. It is made of a material and has a flat surface.

The present embodiment has a more beautiful appearance than the above-mentioned embodiments, and unlike the above-mentioned embodiments, it is sufficient to apply a pressing force in a direction intersecting with the side surface 22 of the container body 2, so that the pump operation is easy. It is easy to apply a pressing force with, and it is also possible to apply a pressing force by stepping on it with a foot, for example.

FIG. 3 shows a further different embodiment of the present invention. The container 1 is formed of an elastic material into a pouch shape, and the side surface 22 of the container body 2 is provided with a suction port 4 and a discharge port 5. Has been.

Further, the gusset portion 24 of the container body 2 is provided with an opening portion 26 having a slide fastener 25 attached thereto.

The sliding fastener 25 is composed of an articulator which is fitted on the inner surface of the opening 26, and a slider 28 which moves along a guide 27 formed in the opening 26 in the longitudinal direction. Thus, when the slide fastener 25 is closed, the opening 26 can be closed in a sealable manner.

The method of use and the operation / effect of this embodiment are almost the same as those of the above-mentioned embodiment, and particularly when the sliding fastener 25 is closed, the open portion 29 is formed at the terminal end without being closed to the end. This allows the open portion 29 to be used as the suction port 4 of the type in which the finger is closed. In this case, it is not necessary to separately provide the suction port 4 and the structure is simple. Excellent in productivity and economy.

Although the above-mentioned embodiments have shown the cases where they are used as discharge type air pumps, it goes without saying that they can also be used as suction pumps for vacuum packs, for example.

[0025]

[Effect of device]

 According to the present invention, by opening and closing the opening, it has a shape and function as a container, and 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 is bulky. There is no.

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 resources, and is also excellent in durability.
