Description

Liquid soft package bag fluid nozzle assembly

Technical field

The utility model relates to a kind of liquid soft package bag fluid nozzle assembly, belongs to the soft packaging bag technology.

Background technology

Packed edible product such as existing liquid such as fruit juice, beverage, wine and soy sauce all come out its packaging bag stabing a hole to the liquid drainage facing the time spent.And existing flexible package punch mould bucket firmly, then on staving, be provided with the fluid mouth and be used for stopping up the pipe cap of fluid mouth.Obvious existing above-mentioned two kinds of flexible package punchs, the former uses very inconvenient, and not only interior dress liquid must once be used up, and can only be used for inner wrapping, and very unhygienic; After then to use be to have made things convenient for, interior dress liquid can be used up in gradation, can be used for big packing.But, if will be implanted on the liquid soft package bag such as the fluid mouth structure of moulding bucket firmly, exist deficiencies such as hindering the packaging bag radiosterilization undoubtedly, particularly the flexible packaging of the good liquid of can is in its logistics progress, can give the pilferage behavior of seizing bag interior liquid, or, change the counterfeit behavior of other liquid inferior with after liquid pouring comes out in the bag, cause opportunity.For this reason, research and develop a kind of liquid soft package bag fluid nozzle assembly, become people's expectation with caution pilferage and counterfeit behavior.

Summary of the invention

The purpose of this utility model is to provide a kind of liquid soft package bag fluid nozzle assembly with caution pilferage and counterfeit behavior, to overcome the deficiency of prior art.

The technical scheme that its purpose that realizes the utility model adopts is, a kind of liquid soft package bag fluid nozzle assembly, have the plastics fluid base that can connect with the heat-sealing of the prefabricated fluid hole of soft packaging bag and can with make fluid base leak free plastics pipe cap, its improvement is: also have plastic union pipe; Connection pipe is provided with seal dissepiment; The cylindrical wall of connection pipe one end and the inner round wall force fit of fluid base are tightly connected; Pipe cap and the connection pipe exit end is removable is tightly connected.

Can understand that by above given technical scheme because the set connection pipe of the utility model has seal dissepiment, thereby in its actual use, aforementioned contingent pilferage and counterfeit behavior all must destroy seal dissepiment.And seal dissepiment is in a single day destroyed, is easy to be found by the people.Thereby realized the purpose of this utility model, safeguarded businessman and customer's interests.This has more outstanding and significant practical significance for the flexible packaging of liquid chemical raw material and fruit drink etc.

The further improvement of the utility model point is:

The force fit of said connection pipe and fluid base is tightly connected, and is that the concavo-convex pair that constitutes mutually by convex shoulder and the some roads convex shoulder institute that is located on the connection pipe cylindrical wall that is located on the fluid base exit end bead inner round wall and both said round wall force fits are tightly connected.Because the existence of said convex shoulder, and under the condition of connection pipe that adopts soft plastic to make and fluid base, because the concavo-convex pair that both flush fits constituted, not only can make both connecting portion sealings, and be not easy very much connection pipe is separated in the fluid base, this has just effectively stoped by changing connection pipe implements the generation of pilferage and counterfeit behavior.

The removable sealed connection of pipe cap and connection pipe be that thread seal connects, or cork turns over the cap sealed connection.Said cork turns over the cap sealed connection, is the rubber cork as medical brine bottle.It can also be at the rubber cork turn over cap outside, aluminum matter buckle closure.This for valuable or to human body and environment have injury such as liquid chemical raw material, the reagent that needs packing and liquid medicine etc., have more significantly anti-the pilferage and the technique effect of anti-personation.

On the set seal dissepiment of connection pipe, be connected with to draw and climb, barrier film with draw climb point of connection along the circumferential direction be provided with the drawing crack groove.This is preferred a kind of version, draws when pulling and climbs, and tears the drawing crack groove of barrier film thereupon, even if got through the passage that storage liquid is discharged in the packaging bag.Certainly climb even only under the condition of a barrier film, poke barrier film not establishing to draw with rotary cutter not establishing the drawing crack groove on the barrier film, storage liquid in draining in the packaging bag, this is very easily.

The outlet end endoporus of connection pipe can be tightly connected with the cylindrical force fit of butterfly valve feed tube.Here said butterfly valve is to be 200520068693.4 butterfly valve at the number of patent application of first to file by applicant.Its purpose obviously is and can convenient gradation discharge opeing of the present utility model uses.

After technique scheme was implemented, caution that the utility model had was stolen, personation packing liquid and characteristics such as simple in structure, easy to use, was conspicuous.

The specific embodiment

In fact by above given accompanying drawing, can understand that the utility model realizes the technical scheme of its purpose.Below in conjunction with the description of accompanying drawing by the specific embodiment, the utility model is described in further detail.

One of a kind of representative type specific embodiment is shown in accompanying drawing 1 to 7.

A kind of liquid soft package bag fluid nozzle assembly, have the plastics fluid base 2 that can connect with the prefabricated fluid hole heat-sealing of soft packaging bag 1 and can with make fluid base 2 leak free plastics pipe caps 4, also have plastic union pipe 3; Connection pipe 3 is provided with the seal dissepiment 3-1 that is used for warning pilferage or counterfeit behavior; The cylindrical wall of connection pipe 3 one ends and the inner round wall force fit of fluid base 2 are tightly connected; Pipe cap 4 and removable being tightly connected of connection pipe 3 exit end.Said connection pipe 3 is tightly connected with the force fit of fluid base 2, is that the concavo-convex pair that constitutes mutually by convex shoulder 2-1 and the some road convex shoulder 3-2 institute that is located on the connection pipe 3 cylindrical walls that is located on the fluid base 2 exit end bead inner round wall and both said round wall force fits are tightly connected.The removable sealed connection of pipe cap 4 and connection pipe 3 be that thread seal connects, or cork turns over the cap sealed connection.On the set seal dissepiment 3-1 of connection pipe 3, be connected with to draw and climb 3-1-1, barrier film 3-1 with draw climb the 3-1-1 point of connection along the circumferential direction be provided with drawing crack groove 3-1-2.The outlet end endoporus of connection pipe 3 can be tightly connected with the cylindrical force fit of the feed tube 5-1 of Chinese patent application 200520068693.4 butterfly valves 5.

The fluid base 2 of the above-mentioned specific embodiment, connection pipe 3 and pipe cap 4 all adopt the food grade polyethylene molding to be shaped.

The concise and to the point description of the utility model fitting process is, with fluid base 2 be installed in by the compound bag 1 of polycarbonate membrane, aluminium film and polyethylene film in the prefabricated fluid hole, and the flange 2-2 of fluid base 2 is fitted on the inwall of bag 1, use liquid base 2 by the pressurization heat-sealing and connect with bag 1 heat-sealing; After then bag 1 connection pipe 3 with fluid base 2 and pipe cap 4 being made the radiosterilization sterilization processing,, can feed fluid can factory use bag 1, connection pipe 3 and pipe cap 4 sealed packages.Liquid has been irritated by filling liquid factory in packaging bag bag 1 after, and then connection pipe 3 is pressed into sealed connection in the exit end endoporus of fluid base 2 in desinfection chamber, loads onto pipe cap 4 at the exit end of connection pipe 3 again, supply can appear on the market.

The utility model lab scale sample detection result shows that its every technical index all meets or exceeds relevant criterion.Use on the liquid soft package bag of capacity 5kg to 1000kg, its technique effect all is good.
