Description

Sealed packing bag

The utility model relates to a kind of sealed package bag, i.e. repeated use repeatedly, and the packaging bag that can keep its sealing property.

Existing sealed package bag mostly is disposable, just is difficult for sealing in case open the back.Reused packaging bag is also arranged, as Chinese patent CN91208666.1 " wet tissue packaging bag mounting ", it comprises the non-breathing zone that is fixed in the packaging bag, repeats to paste the district with non-breathing zone connects together, be the joint with the embossing between two districts, and distinguished with different cloth glue density, non-breathing zone is fixed in packaging bag opening one side to be coated with glue face or thermal welding mode fully, repeats to paste the district and is coated with in a glue mode, and spreading area is about 1/2nd of the whole district.Its weak point is that the packaging bag mounting adopts two kinds of coating methods or bonding way, thereby processing difficulties, adopts some glue mode to be coated with owing to repeat to paste the district, thereby poor sealing, is difficult for reaching complete leak free requirement.

The purpose of this utility model is to propose a kind of product that the needs sealing is preserved, reused sealed package bag of being used for.

The purpose of this utility model is achieved in that this packaging bag is made up of bag, sealing pressure sensitive adhesive lid, hot sealing line, bag connection lead, break line, opening, glue lid break line and unlatching handle etc.Bag is made by plastic sheeting, can adopt polyethylene film, polypropylene screen, polychloroethylene film, polyester film and various complex film.The bag periphery adopts the hot melt sealing, and an opening is arranged in the middle of it.Open circumferential does not have the dead angle, and opening is rounded, oval or not with any geometric figure at dead angle.One end of opening links to each other with bag.Sealing pressure sensitive adhesive lid adopts pressure sensitive adhesive paper to make.The shape and the opening shape of sealing pressure sensitive adhesive lid are unanimous on the whole, and opening end stays one to open handle, so that open at any time or sealing.

The utility model has the advantages that: 1. simple in structure, easy to use, can realize repeatedly air-tightness requirement, after taking out portioned product, can seal and keep original air-tightness at once, can polluted product; 2. do not need the special process manufacturing, air-tightness is good, need to be specially adapted to the product of sealing preservation, adopts this packaging bag can prolong the holding time of product greatly; 3. easy to carry, with getting, do not spill and do not leak with usefulness, changeable, cheap.

Accompanying drawing of the present utility model has:

Fig. 1 sealed package bag schematic perspective view.

Fig. 2 sealed package bag constructions scheme drawing.

Fig. 3 sealed package bag bag opening figure.

Fig. 4 sealed package bag sealing pressure sensitive adhesive lid scheme drawing.

Below in conjunction with drawings and Examples the utility model is further described.

From Fig. 1 and Fig. 2 as can be seen, this sealed package bag is by bag 1, sealing pressure sensitive adhesive lid 2, hot sealing line 3, bag connection lead 4, break line 5, opening 6, glue lid break line 7 with open handle 8 etc. and forms.Bag 1 adopts polyvinyl chloride film, and sealing pressure sensitive adhesive lid 2 is in bag 1 positive central authorities.Stick sealing pressure sensitive adhesive lid 2 on the empty bag 1 earlier.Sealing pressure sensitive adhesive lid 2 need be adjacent to bag 1 surface, and it is correct that no air gap, particularly position are wanted, and can not paste partially.Product on the bag 1 adopts conventional heat posted to seal, as high-frequency thermocompressor.During use, will seal pressure sensitive adhesive lid 2 from the unlatching handle 6 of sealing pressure sensitive adhesive lid 2 and draw back, and take out or pour out product, will seal pressure sensitive adhesive then gently and cover 2 pressings, compress from opening 6.Packaging bag just returns to when not opening the same.Because therefore bag material difference should adopt corresponding pressure sensitive adhesive to obtain best sealing effectiveness when selecting pressure-sensitive gummed paper.Generally can adopt polyacrylate pressure-sensitive.Sealing pressure sensitive adhesive lid 2 should be greater than opening 6, at least 10 millimeters on every limit, at least 20 millimeters at two ends.The shape of sealing pressure sensitive adhesive lid 2 and the shape of opening 6 should be unanimous on the whole, but opening end will stay one to open handle 8, so that open at any time or sealing at any time.

Fig. 3 is a sealed package bag bag opening scheme drawing.Opening 6 is made up of bag connection lead 4 and break line 5 two parts, its size with the visual product in position and different, should be noted that 2 points: the geometric configuration of (1) opening 6 must not have dead angle and broken line.Because of dead angle and broken line can cause tearing of packing opening 6 when opening, thus destroyed opening 6 air-tightness and can not repeated use.(2) position one end of opening 6 should link to each other with bag 1, and when sealing pressure sensitive adhesive lid 2 like this and opening, the inside face of sealing pressure sensitive adhesive lid 2 is close at this position just, pressure sensitive adhesive just not can with the product direct contact.Opening 6 can adopt complete breakaway-element, also can adopt dotted line to be interrupted breakaway-element, promptly connects muscle formula structure.Should be noted that when adopting the dotted line breakaway-element that different packing point linear distances is appropriate, in order to avoid produce the problem of not opening, so complete breakaway-element structure is adopted in this packaging bag.

Fig. 4 sealed package bag sealing pressure sensitive adhesive lid scheme drawing.Its design should be noted that: (1) necessity has opens the pressure-sensitive adhesive of opening handle 8 places behind handle 8, the especially repeated use and can descend with joint efforts, but is unlikely the sealing property that influences packaging bag.The position of opening handle 8 can be placed on bottom righthand side, also can be placed on other correct positions.(2) line of opening 6 is crucial, and it can prevent to open the sealing pressure sensitive adhesive and cover and caused sealing pressure sensitive adhesive lid 2 to come off at 2 o'clock, promptly plays the effect that sealing pressure sensitive adhesive lid 2 breaks away from bags 1 that stops.The geometric figure of glue lid break line 7 also can be varied, but the distance between its both ends open 6 lines and the line is not less than 15 millimeters, tears to guarantee that the sealing pressure sensitive adhesive does not produce when covering 2 repeated uses.

The operating process of this sealed package bag is as follows: according to bag material and the pressure-sensitive gummed paper that product select to use, the oad of decision packaging bag is determined the size of opening 6 according to the performance of product, with the convenient product that takes out.Design opening 6 shapes, position and leak free size, correctly stick sealing pressure sensitive adhesive lid 2 at opening 6 positions, use wrapping machine or Manual Packaging then.

Claims (2)

1, a kind of sealed package bag, it is characterized in that: by bag (1), sealing pressure sensitive adhesive lid (2), hot sealing line (3), bag connection lead (4), break line (5), opening (6), glue lid break line (7) and unlatching handle (8) are formed, sealing pressure sensitive adhesive lid (2) is in the central authorities of bag (1), draw back sealing pressure sensitive adhesive lid (2) from the unlatching handle (8) of sealing pressure sensitive adhesive lid (2), sealing pressure sensitive adhesive lid (2) is greater than opening (6), at least 10 millimeters on every limit, at least 20 millimeters at two ends, the shape of sealing pressure sensitive adhesive lid (2) and the shape of opening (6) are unanimous on the whole.
