Abstract

The utility model provides a packing container with a leak proof ventilating cover, comprising a container body and a closing cover. Ventilating leak proof devices are provided on the closing cover. Wherein, a ventilating leak proof device is provided with a convex slot on the bottom face of the closing cover. The top part of the convex slot is provided with at least one riser vent. The inner face of the top part of the convex slot is placed a breathable film. In addition, a pressed film element is buckled in the convex slot, and the breathable film is pressed tightly by the outer surface of the top part. The top part of the pressed film element is provided with air vents which are corresponding to the riser vents on the convex slot one by one. The packing container with the leak proof ventilating cover of the utility model is mainly used for encapsulating high-temperature liquid or volatilizing articles. After encapsulating, the packing container with the leak proof ventilating cover can also exhaust a large quantity of gas which is evaporated and volatilized out the container timely while the air tightness of the liquid or the solid in the container can not be influenced.

Description

The packing container of the ventilative leakage-proof cover of band

Technical field

The utility model relates to the packing container technical field, in particular for the packing container of the ventilative leakage-proof cover of band of encapsulation high-temp liquid or volatile one.

Background technology

At present, when needing can high-temp liquid or volatile one, can only use packing containers such as common plastics or metal drum, jar.The current packaging container is made up of container body and airtight capping.Capping is by being connected with the vessel port outer wall thread, play liquid in the leakproof tank, prevent the effect of fluid seepage, but simultaneously also airtight gas in the container makes and forms a fully enclosed space in the container.When stating the container filling high-temp liquid in the use, the high-temp liquid in the container can be discharged a large amount of steams, seals if can finishes, and then the interior pressure of container can sharply increase, and causes the container body distortion or breaks at once.Do not seal after finishing so existing way is can at once, have only the fluid temperature of waiting in the container to descend after, just can seal and transport, directly influence production efficiency.And when can high-temp liquid food, for guaranteeing the hygienic requirements of food, need behind high-temperature filling, seal, so just make steam in the container can't discharge and cause the danger of container body distortion or explosion. at onceIn addition, when the packing volatile one, article in the container are because constantly volatilization, container inner pressure is constantly increased, when acquiring a certain degree, pressure can make container body distortion or explosion, particularly meet the volatile one that flash-point can burn, if do not have airing function then can set off an explosion or catching fire.

Summary of the invention

The technical problems to be solved in the utility model is can be with outside evaporation or the gas amount discharge container that evaporates after packing container is packaged with high-temp liquid or volatile one, thereby avoids the packing container distortion or break.

The technical scheme that its technical matters that solves the utility model adopts is: the packing container of the ventilative leakage-proof cover of band, comprise container body and with the suitable capping of container body top open part; In capping, be provided with ventilative leak-proof device.

Described ventilative leak-proof device is to be provided with at least one breather hole on the capping bottom surface, and fixedly is bonded with ventilated membrane in the inboard, capping bottom surface corresponding to breather hole.This ventilated membrane can allow the interior gas of container pass through, and liquid or solid is impassabitity then.

The another kind of mode of described ventilative leak-proof device is to be provided with a tongue in capping, this tongue top has at least one breather hole, also be provided with a press mold spare, its top has breather hole, and it is corresponding one by one with the tongue breather hole, be equipped with ventilated membrane in the tongue top underside, described press mold spare is fastened in the tongue, and its outside, top compresses this ventilated membrane.

As further improvement of the utility model, described capping is that this ventilative leakproof inner cap is inlaid in the packing container opening part when breathing freely the leakproof inner cap, adds enclosing cover to be threaded with this opening part, and compresses ventilative leakproof inner cap; Described capping is when breathing freely the leakproof enclosing cover, directly to be threaded with the packing container opening part.The shape of above-mentioned breather hole can be that circular net is poroid or cross is poroid.The best shape with described tongue inner chamber of the shape of above-mentioned press mold spare is complementary, and is a cavity in the middle of it, and the below is provided with opening.

Tongue is set in capping, can makes the liquid in ventilated membrane and the container keep certain space and distance, avoid the liquid in the container because rock in transit or canting and stick to the gas that makes on the ventilated membrane in the container and be difficult to discharge.Install press mold spare additional, can be further fastening and the protection ventilated membrane, prolong its service life.

The beneficial effects of the utility model are, behind encapsulation high-temp liquid or volatile one, its evaporation or a large amount of gases that volatilize in time can be given off the external of container, avoid the danger that causes container deformation, breaks or explode because air pressure inside sharply increases; Also avoid simultaneously the trouble of capping at once after the embedding, guaranteed the degree of purity of material in the container, improved production efficiency.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the cutaway view of first specific embodiment of packing container of the ventilative leakage-proof cover of the utility model band.

Fig. 2 is the cutaway view of another specific embodiment of packing container of the ventilative leakage-proof cover of the utility model band.

The specific embodiment

Embodiment 1

The packing container of the ventilative leakage-proof cover of band shown in Figure 1 is made up of container body 1 and capping 2, is provided with the breather hole 3 of a circle in the bottom of capping 2, and the week edge heat seal hermetically that a ventilated membrane 4 and capping 2 lower surface breather holes 3 are arranged together.

Embodiment 2

Among another embodiment shown in Figure 2, be provided with a columniform tongue 5 in the bottom of capping 2, one circular breather hole 3 is arranged at the top of tongue 5, the press mold spare 6 of a size, shape and the tongue 2 inner surface configurations coupling of in tongue 5, packing into, two to four shrinkage pools 9 are arranged on this press mold spare 6 sidewalls, tighten mutually with the projection 8 on the tongue side inner walls, become a fastening structure.Having a ventilated membrane 4 to be placed between tongue 2 top lower surfaces and the press mold spare 6 top upper surfaces and by both clamps.In the middle of this press mold spare 6 is cavity, lower opening, with capping on breather hole 3 cooresponding positions be provided with identical shaped air gate 7.

During use, ventilative leakage-proof cover on can high-temp liquid or the volatile matter bonnet in container body, high-temp liquid or volatile matter evaporation or a large amount of gases that volatilize can see through ventilated membrane and be discharged into outside the container body from breather hole, make the air pressure in the container body keep consistent with barometric pressure, the liquid or solid in the container body then is closed in the container body owing to not penetrating ventilated membrane.

Certainly, this ventilative leakage-proof cover can directly use as enclosing cover, also can be used as inner cap and uses.And the shape that the shape of breather hole can be a mesh, cross is poroid or other is suitable for, quantity can be one or more.The shape of tongue also can be criss-cross, square or other shape that is suitable for.Such conversion all drops within the protection domain of the present utility model.
