Abstract

The utility model relates to a package bag which is characterized in that the upper end of the package bag is provided with an access door which has the characteristic of a one-way valve under a natural state to make articles in the package bag unable to automatically flow out. A flow guide pipe is only required to be inserted, and the articles can be led out or arranged in the package bag as required. The access door effectively prevents the articles in the package bag from automatically flowing out through the arrangement of a flow check tongue or similar labyrinth seal. The utility model has the advantages of low cost, simple structure, and convenient operation. The utility model is suitable for packing gaseous, liquid, colloid, powdery, granular, and solid articles and is especially suitable for packing beverages, food and travel articles.

Description

Convenient self-sealed packing bag

The utility model relates to a kind of packaging bag, is applicable to the packing of gaseous state, liquid state, colloid shape and solid-state (granular, powdery) article.

Existing soft packaging bag is disposable, and after in a single day bag being opened, owing to can't seal once more, interior items must in time use up.This brings very big inconvenience to industrial packaging and daily life, and the packing to travel beverage, food is extremely inconvenient especially.

The utility model promptly at above-mentioned not enough propose a kind of simple in structure, be easy to carry, sealing and repeatedly used novel package bag automatically.

Solution of the present utility model is: establish a gangway in the upper end of soft packaging bag.Make the article that easily flow in the bag not to flow out automatically from the gangway according to fluid mechanics boundary 1ayer theory, diffusion effect, Powdered, granular solid matter is the gas-solid two-phase when mobile, so can not flow out automatically from the gangway.During article, only need to insert a mozzle in needs use bag, the interior article of bag can flow out along mozzle.Extract mozzle out, sack seals automatically.In like manner, by mozzle, gaseous state, liquid state and powder, granular solid matter can be packed in the bag simply, easily.

Advantage of the present utility model is: this packing forms the check valve effect, can seal the gangway at any time automatically, guarantee that article can not flow out automatically in the bag, be very suitable for the article packing of flow regime, especially the packing to beverage, food and travel goods is very easily.Good automatic seal, also can make the customer feel safe, convenient, healthy.In addition, this packaging bag production technology is simple, and cost is low, and is reusable.

Accompanying drawing has been described embodiment of the present utility model

Accompanying drawing 1 is a structure principle chart of the present utility model.Accompanying drawing 2 is that I type gangway constructional drawing accompanying drawing 3 is the cutaway view of I type gangway, is adapted to the packing of gaseous state, liquid state, colloid shape and particulate, Powdered solid-state article, and can be repeatedly used.

As follows to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, accompanying drawing 6, accompanying drawing 7 and specification digest description of drawings:

1. leaf 4. gangway inferior lobes on 3. gangways, packaging bag 2. gangways

5. fluid stopping tongue 6. sealed knot lines 7. mozzles

The fluid stopping tongue of comparatively soft up/down perforation is packed in the passage of being made up of leaf on the gangway and gangway inferior lobe, contain length mutually and account for fluid stopping tongue 2/3.Again that the outside, fluid stopping tongue upper end is closely connected with upper and lower leaf, the article that import from the upper end can only be carried by fluid stopping tongue internal channel.At last this gangway is encapsulated in the packaging bag.

Because the bag inner fluid is that its boundary layer thickness is less than 0.1mm under the condition on border in this gangway.Simultaneously fluid stopping tongue material is thinner, and it is thicker to import and export upper and lower leaf material, thus the natural Zhang Du of fluid stopping tongue import and export upper and lower leaf to open degree much smaller, a bag inner fluid very easily enters fluid stopping tongue exocoel, makes fluid stopping tongue inner chamber be subjected to the external force pressure gap and becomes littler.It is big more to have formed the packaging bag internal pressure, and this packaging bag sealing effect is good more, and article can't be excessive in the bag, also promptly formed a check valve.

Simultaneously owing to selected soft material to do the fluid stopping tongue, and the fluid stopping tongue to have only an end be free end, thereby the fluid stopping tongue can only soften and can not servo-actuated.Add the sealed knot line that is provided with by relative position, formed the sealing of class maze type, the boundary layer thickness that has not only guaranteed runner is less than 0.1mm, and constituted stable diffusion district again, further stoped the outflow of dynamic fluid.

Accompanying drawing 4 is an II type of the present utility model, is applicable to the packing of gaseous state, liquid state, glue and particulate, Powdered solid-state article, but is applied to the lower occasion of repeat usage.Accompanying drawing 5 is its lateral plan.

Accompanying drawing 6 is an III type of the present utility model, is applicable to the packing of the bigger liquid state of viscosity, colloid shape, microgranular solid-state article, is the simplest a kind of structure, and accompanying drawing 7 is its lateral plan.II type, III type are the same with the I type all to be to give full play to the gangway that the diffusion choked flow effect of fluid realizes automatic closing function.The II type is to utilize the fluid stopping tongue, and the III type then is to utilize orderly sealed knot line to form class labyrinth seal, produces stable diffusion district, thereby realizes the function of automatic choked flow.

Claims

1, the self-enclosed packaging bag of a kind of convenience is made up of packaging bag and gangway, it is characterized in that being provided with in the gangway fluid stopping tongue and orderly sealed knot line, has formed the fluid stopping chamber, makes the gangway possess unidirectional performance of ending.

2, the self-enclosed packaging bag of convenience according to claim 1, it is characterized in that being that fluid stopping tongue and sealed knot line have formed class labyrinth seal under the condition of dredging without the people, and under artificial water conservancy diversion, (plug in a conduit), the fluid stopping chamber can be opened at any time, and article in the bag are derived.
