Abstract

The utility model relates to a volume variable container, which comprises a container body (1) and a cover component. The cover component comprises a tubular telescopic body (2) and a cover body (3). The tubular telescopic body (2) is arranged in the container body (1). The upper end of the tubular telescopic body (2) is arranged at a container opening, and a sealing part (7) is arranged on the periphery of the lower end of the tubular telescopic body (2), and is tightly connected with the inner wall of the container body (1). The cover body (3) is matched with the inner periphery of the lower end of the tubular telescopic body (2). An air vent (6) and a knob (5) beside the air vent (6) are arranged on the cover body (3). The air vent (6) can be opened or closed by rotating the knob (5). The volume variable container has the advantages that the size of the tubular telescopic body can be changed according to the number of contained objects to reduce air in the container body, so that the damping of the objects in the container body or the chemical reaction of the objects with the air can be reduced or retarded.

Description

A kind of container tank of variable volume

Technical field

The utility model relates to a kind of container, more particularly, relates to a kind of container tank of variable volume.

Background technology

The existing tank body that is used for holding article, its volume of great majority can not change, and when the article in the tank body were fewer and feweri, the air in the tank body was just more and more, article just make moist easily, perhaps with airborne water vapour, oxygen generation oxidizing reaction or decomposition reaction.

The utility model content

The purpose of this utility model provides a kind of container tank of variable volume, and the volume that solves existing tank body can not reduce with the minimizing that holds article, makes the interior air of tank body too much cause the rotten problem of article in the tank body.

The technical solution of the utility model is: a kind of container tank of variable volume, comprise tank body and cap assemblies, it is characterized in that, described cap assemblies comprises cast extrusome, lid, described cast extrusome is inserted in the tank body, its upper end is installed in a jar mouth, the periphery of its lower end is provided with sealing member, the inwall tight joint of sealing member and tank body, the interior Zhou Peihe of described lid and cast extrusome lower end, the knob that is provided with air extractor vent above the described lid and is arranged on described air extractor vent next door, the rotation knob can open or close air extractor vent.

In the container tank of the above-mentioned variable volume of the utility model, described cap assemblies also comprises the handle that is installed on the lid.

In the container tank of the above-mentioned variable volume of the utility model, the cross-sectional plane of described sealing member is the fin shape.

Enforcement the utility model has the advantages that: can according to how many compression volumes that hold article, reduce the air in the tank body, the article that reduce or delay in the tank body make moist, and reduce or delay article and the interior airborne water vapour of tank body, oxygen generation oxidizing reaction or decomposition reaction in the tank body.

The specific embodiment

The utility model comprises tank body 1, cap assemblies, and wherein, cap assemblies comprises cast extrusome 2, lid 3, as can be seen from Figure 1.Be provided with air extractor vent 6, knob 5 above the lid 3, knob 5 is arranged on the next door of air extractor vent 6, and air extractor vent 6 can be opened or close to rotation knob 5, comparison diagram 2, Fig. 3, and perhaps comparison diagram 6, Fig. 7 are as can be seen.Lid 3 is provided with handle 4, and the interior Zhou Peihe of lid 3 and cast extrusome 2 lower ends waits as can be seen from Fig. 6.Described cast extrusome 2 is inserted in the tank body 1, and its upper end is installed in a jar mouth, and the periphery of its lower end is provided with sealing member 7, the inwall tight joint of sealing member 7 and tank body 1, and sealing member 7 is the fin shape, waits as can be seen from Fig. 6.

Cast extrusome 2 is made for plastic material, and it can stretch or shrink, when air extractor vent 6 is in open mode, and downward gland body 3, cast extrusome 2 can stretch in tank body 1; Upwards draw lid 3, cast extrusome 2 can shrink outside tank body 1, comparison diagram 2, Fig. 4, and perhaps comparison diagram 6, Fig. 8 are as can be seen.

When the article that hold in the tank body 1 reduce, a layer of air is arranged in just between article and the lid, at this moment, air extractor vent 6 is opened, downward gland body 3, cast extrusome 2 stretches downwards, and the air in the tank body 1 is discharged from air extractor vent 6, and comparison diagram 6, Fig. 8 are as can be seen, close air extractor vent 6 then, the air that prevents the outside is back in the tank body 1, and the air in the tank body 1 has just reduced like this, as can be seen from Figure 9.Therefore, along with the article of depositing in the tank body 1 reduce gradually, can reduce the volume of tank body 1 gradually, reduce the air in the tank body 1 gradually, thereby the article that can reduce or delay in the tank body 1 make moist, and reduce or delay article and tank body 1 interior airborne water vapour, oxygen generation oxidizing reaction or decomposition reaction in the tank body 1.

The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
