Description

A kind of novel seal packing jar

Technical field

Packing container is the utility model is related to, more particularly to a kind of novel seal packing jar.

Background technology

In the prior art, the storage of tealeaves is packed frequently with iron flask, and lid and the comparison that tank body can coordinate are close, this Sample lid is not easy to disengage from tank body, and tightness is good.But as the lifting of consumption idea, people increasingly grow tender of papery Jar carries out the packaging of industry.The jar of papery is typically using metal, plastics or the manufacture of bamboo and wood material.Due to tank material Soft limitation, lid are relatively difficult to coordinate with tank body, typically will be by the way of inner bayonet to reach the effect of sealing Tank body oral area is set to be caught in the groove of lid.

Meanwhile to ensure the sealing of jar, generally also need to be sealed using thin film in jar oral area, in order to Ensure attractive in appearance, film is generally arranged at the lower section of lid.

When carrying out sealed cans using general film, because film surplus of stretching is small, in processing and manufacturing, surface creases easily deformation.

And due to tank interior integral sealing after sealed cans, when causing tank interior due to temperature rise or other reasonses During gas expansion, larger pressure, the film that can rise brokenly when serious for sealing can be produced to film.

Further, since the presence of central stress, when film inner side is under pressure, maximum deformation occurs for its middle body, It is easy to eject on lid.

In some embodiments, sealed cans face edge is additionally provided with for pull-up and removes the tear tape in sealed cans face.

Novel seal packing jar provided by the utility model, compared with prior art, there are following advantageous effects：

(1), the sealed cans face of diaphragm seal is provided with waveform configuration, can absorb or provide deformation surplus, and can recover Original state, thus in processing and manufacturing, surface does not crease easily, and will not also deform；

(2), waveform configuration is flexible, it is possible thereby to increase the intensity in sealed cans face, makes sealed cans face will not be because of tank interior Gas expansion causes to rise brokenly；

(3), waveform configuration can eliminate central stress, make sealed cans face uniform force, by tank interior gas pressure When so as to reduce the intensity of sealed cans face deformation, and then can be avoided on pressure dissipation to whole sealed cans face by lid top Go out.
