Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a container that also serves as an air pump used when 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 made up of large inflatable bodies have recently appeared, and for example, bellows and bellows. Shaped air pump is 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]

 The present invention has a sealable opening / closing portion, an intake port and an outlet port that are open to the outside, and further, a flexible portion is formed on at least a part of the surface, and along the flexible portion of the surface. A container that also functions as an air pump for inflating a hollow inflatable body such as an air pillow or a floating bag that is convenient to carry without being bulky, characterized by having a spring plate urged outward To achieve the purpose of providing.

[0006]

[Action]

 The contents are housed inside by opening and closing the opening and closing part.

Further, when the flexible portion of the surface is pressed against the biasing force of the bed plate while the opening / closing portion is sealed and the suction port is closed, the pressure inside the container rises and air is discharged from the discharge port. When discharged, the suction port is opened to release the pressing force, the side surface returns to its original state by the biasing force of the leaf spring, at which time the check valve opens and air is introduced into the hollow portion.

[0008]

【Example】

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

1 and 2 show an embodiment of the present invention, in which a container 1 is made of, for example, a soft synthetic resin and has a substantially rectangular shape, and an opening / closing portion 11 is formed along a side edge extending in the longitudinal direction. A single leaf spring 3 made of, for example, a hard synthetic resin having elasticity has open end edges 31, 32 in the bag body 2 formed into a bag shape over the front surface 21 and the rear surface 22 thereof. Along the inner edge of the opening / closing part 11, the whole is bent in a substantially cylindrical shape.

When an external pressure against the biasing force of the leaf spring 3 is applied to the front surface 21 or the rear surface 22, the front surface 21 or the rear surface 22 is dented, and when the external pressure is released, the original state can be automatically restored. ing. In particular, this embodiment has a structure in which both end edges 31 and 32 of the leaf spring 3 are fitted into the grooves 12 and 13 formed on the inner surface of the opening / closing portion 11 to prevent the displacement.

Further, the opening / closing part 11 is provided with a slide fastener 4.

The sliding fastener 4 includes articulators 41 and 42 that are fitted to each other on the inner surface of the opening / closing portion 11, respectively, and two sliders 44 that move along guides 43 formed in the opening / closing portion 11 in the longitudinal direction. , 45, and in particular, the two sliders 44, 45 are brought into contact with each other at portions other than the ends of the opening / closing portion 11 to close the opening / closing portion 11 in a sealable manner when the sliding fastener 4 is closed. Is something that can be done.

Further, a suction port 5 and a discharge port 6 are formed in the front surface portion 21 of the container body 2, and a check valve 51 that can be opened inward is fitted to the suction port 5. A discharge nozzle 61, which is formed separately, is fitted into the discharge outlet 6.

This embodiment can be used as a container by operating the slide fastener 4 to open and close the opening / closing portion 11, and for example, an air pillow inflated by this air pump or other articles such as clothes and towels can be used. Can be accommodated and carried.

To use as an air pump, the sliding fastener 4 is operated to seal the opening / closing portion 11 and an external pressure against the biasing force of the leaf spring 3 is intermittently applied to the front surface 21 or the rear surface 22 so that the front surface 21 is closed. Alternatively, the rear surface 22 is dented and automatically returns to the original state when the external pressure is released.

Therefore, when external pressure is applied, the front surface 21 or the rear surface 22 is dented, the check valve 51 is closed and the internal pressure rises, air is discharged from the discharge nozzle 61 via the discharge port 6, and the pressing force is increased. When is released, the front surface 21 or the rear surface 22 automatically returns to the original state, the check valve 51 opens, and air is introduced into the interior, and as a result, compressed air is intermittently discharged from the discharge nozzle 61. Is ejected. Particularly, when used for an inflatable body that needs to be filled with compressed air such as a balloon, it is preferable to provide a check valve at the projecting port 6.

As described above, this embodiment can be normally used as a container and can function as an air pump when necessary, so that the air pump does not need to be carried separately, which is extremely convenient and bulky. It is extremely effective in saving resources.

In this embodiment, the container main body 2 is formed of a soft synthetic resin, but a flexible portion is formed on a part of the surface such as the front surface 21 or the rear surface 22 and the surface is soft. It is sufficient that the spring plate urged outward along the soft portion is additionally provided.

FIG. 3 shows another embodiment of the present invention, in which a flexible portion 24 is formed on a part of the front surface 21 constituting the surface.

Although the discharge nozzle 61 is provided as a separate body in the above embodiment, the discharge port 6 may be directly provided with the nozzle as a single body.

Further, in each of the above-mentioned embodiments, the case where it is used as a discharge type air pump is shown, but it goes without saying that it can also be used as a suction pump such as for a vacuum pack.

[0022]

[Effect of device]

 According to the present invention, in addition to having the shape and function as a container and the function as an air pump in the same state, 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.
