Description

A kind of packing jar of adjustable volume

Technical field

The utility model is related to a kind of packing jars, and in particular to a kind of packing jar of adjustable volume.

Background technology

At present, mainly there are metal can class, glass jar class, plastic tank class in the market, the time that plastic tank occurs is not grown, but sends out Exhibition is very rapid, and in many occasions instead of metal can and vial, this is primarily due to it and has many advantages：Quality Gently, the density of material for manufacturing plastic tank is smaller, is compared by the identical container mass of volume, plastic tank is than metal iron flask and glass Bottle is small, and cost is relatively low；The fee of material of plastic tank is relatively low, and manufacture is also easier to, therefore total price is more honest and cleaner, can reliably protecting product； Can body is combined for multiple material, there is good chemical stability and barrier property；Plastic tank is as a kind of packing container It is widely used in packaging field, but in use, the volume of packing jar is not due to having changeability, the commodity in tank After reduction, our space can be still wasted, the very big commodity of packing jar intensity are not needed at some, if can be according to making With the volume of adjustment packing jar, it is easier the article taken in packing jar when in use, when storage saves our space, uses Getting up can enhanced convenience.

Utility model content

Technical problem to be solved in the utility model be the volume of existing packing jar due to there is no changeability, in tank After article is using reducing, our space is wasted in storage, and it is an object of the present invention to provide a kind of packing jar of adjustable volume, solves The volume of existing packing jar is not due to having changeability, and after article is using reducing in tank, our space is wasted in storage The problem of.

The utility model is achieved through the following technical solutions：

A kind of packing jar of adjustable volume, the packing jar ontology including plastics, the tank body of packing jar ontology are uniformly arranged There is telescopic fold, packing jar body interior is provided with the supporting rack of plastics.Plastic tank exists as a kind of packing container It is widely used in packaging field, but in use, the volume of packing jar is not due to having changeability, and commodity make in tank After reduction, our space can be still wasted, therefore, by setting telescopic pleat on the tank body of Plastic packing jar Wrinkle can increase packaging tank volume in use, stretching tank body, and fold is since with changeability, the plastics used are soft Plastics, such packing jar uses and at some does not need to the very big article of packing jar intensity, when article is reduced in tank, by briquetting Tinning, you can reduce packaging tank volume, the volume of packing jar can be adjusted according to actual needs by utility model, made Used time is easier to take the article in packing jar, and when storage saves our space, and using can enhanced convenience；It considers Packing jar may be extruded in transit, and tank body is caused to compress, and to article in tank body into extruding, therefore contained During the article that cannot be extruded, by setting supporting rack, it can prevent tank body from shrinking, in order to avoid article in tank is caused to squeeze.

Further, every fold width is between 0.5~0.8cm.The width of fold is too small, can influence volume and adjust model It encloses, fold is wide, and fold folds during compression, can influence packing jar internal diameter, squeeze article, be existed by the width for designing fold Between 0.5~0.8cm, it can ensure the adjusting range of packing jar, and excessive variation will not be generated to the internal diameter of packing jar.

Further, supporting rack lower end is annulus, and the upper end of annulus is provided with stent foot.It is secured the stand to by annulus In packing jar, by the effect of stent foot, when packing jar receives extruding, since stent foot withstands the top of packing jar, it is allowed to It will not deform.

Further, stent foot ontology is evenly distributed with multiple snap slots.In use, it needs to compress packing jar When, length that the length of stent foot is needed to be needed at us, just can when packing jar compressed, fractureed by being set on stent foot Slot when needing compressed package tinning, is as desired fractureed extra stent foot by snap slot, you can realize the pressure of packing jar Contracting.

Further, stent foot is 3.According to the principle of 3 point one sides, a stent sets 3 stent foots can be one The lid of packing jar is supported on a face, is allowed to more stable.

The utility model compared with prior art, has the following advantages and advantages：

1st, a kind of packing jar of adjustable volume of the utility model can be stretched by being set on the tank body of Plastic packing jar The fold of contracting is provided with every fold of supporting rack of plastics in packing jar body interior, and packaging tank body can be made by stretching tank body Product increase, since with changeability, the plastics used are soft plastics, such packing jar use does not need to wrap fold at some The very big article of tinning intensity when article is reduced in tank, presses packing jar, you can reduces packaging tank volume, by practical new Type can adjust the volume of packing jar according to actual needs, be easier the article taken in packing jar when in use, storage Our spaces of Shi Jieyue, using can enhanced convenience；It can prevent tank body from shrinking, in order to avoid article in tank is caused to squeeze Pressure；

2nd, a kind of packing jar of adjustable volume of the utility model, by design the width of fold 0.5~0.8cm it Between, it can ensure the adjusting range of packing jar, and excessive variation will not be generated to the internal diameter of packing jar；

3rd, a kind of packing jar of adjustable volume of the utility model, by setting snap slot on stent foot, when needing to press During contracting packing jar, extra stent foot is fractureed by snap slot as desired, you can realize the compression of packing jar.
