Definitions
- a ABSTRACT A method for packaging a flowable material comprising folding a flattened tubular film of a thermoplastic material such as polyethylene so that both sides thereof are folded inward; sealing the thus folded tubular film at the position which is to be the top of the finished package; unfolding the opening of the folded tubular film so that the inwardly folded portions are turned outward and the opening comprises two layers; introducing a flowable material in the thus formed bag; sealing the opening in thetwo layer state; and pressing flat the two layer sealed end to form a bottom.
- An apparatus for manufacturing thermoplastic packaging bags to be used for this method is disclosed, too.
- This invention relates to a packaging method for perfectly sealing flowable materials including liquid etc. and an apparatus for manufacturing packaging bags to be used for said method.
- a tubular film of a thermoplastic material is folded flat whereby both sides are folded inward as seen in FIG. I, the flat folded film is cut at a predetermined length, one end of the cut tubular film piece is heat-sealed, the sealed part is made flat to form a bottom, a flowable material such as liquid is introduced in the thus formed bag from the opposite opening end, that is, a top of the bag, and finally the opening end is heat-sealed.
- This invention is to provide a method of perfect sealing of a package of flowable materials such as liquid (milk, fermented milk, fruit juice, oils, soup, etc.) and pasty materials (yogurt, for instance).
- liquid milk, fermented milk, fruit juice, oils, soup, etc.
- pasty materials dairy materials
- the method of this invention comprises forming a folded packaging material by folding a flattened tubular film of a thermoplastic material so that the both sides thereof are folded inward; sealing said folded packaging material at the position which is to become the top after the packaging is finished; unfolding the opening spaced from the sealed portion by a predetermined distance so that the inwardly folded portions are turned outside and the opening comprises two layers; introducing a flowable material through this opening; sealing the opening in the two layer state; pressing flat the two layer sealed end so as to form a flat bottom.
- a tubular film packaging material is sealed at the position which is to become the top of a finished package prior to introduction of a flowable material, and the opening which is to become the bottom of the finished package is unfolded so that the inwardly folded sides are turned outward, and a flowable material is introduced in the thus formed bag, and the opening is sealed in the two layer state.

- FIG. 11 is a schematic elevational side view of an apparatus for manufacturing packaging bags of thermoplastic film used in the method of this invention.
- FIGS. 12, 13, 14,15, 16 and 17 are cross sections along lines l2 12, 13-13, l4--l4, l515, l6l6 and l7l7 in FIG. 11, respectively.
- a folded packaging material 1 is formed by foldinga tubular film of a thermoplastic material such as polyethylene so that both sides are turned inside to form folded portions A AND B.
- the folded packaging material comprises two four-layer portions X which consists of outer films C and D and inwardly folded portions A or B and a two-layer portion Y which consists of two outer films C and D.
- the thus formed folded packaging material 1 is sealed, for instance, by heat sealing by means of heat-press members 2 and 3 at the position which is to be the top of the finished package, and is cut off at the position immediately below the seal.
- a packaging bag is obtained, in which a flowable material is to be contained.
- the packaging bags can also be prepared by first cutting a continuous folded tubular film at the position which is to be the top of the finished package and then sealing the cutted end.
- a hole for sucking the contents out and a sealing film to close said hole are shown at 4 and 5 respectively.
- an air-blowing tube 13 is inserted into the opening as shown in FIG. 4, and at the same time a pair of press members l4 and hold the opening therebetween so that the opening remains inthe two layer state.
- the press members Hand 15 are respectivelyprovided with a semicircular recesses .16 and 17 to receive the air blowing tube 13.
- the bag expands so as to conform with the configuration of the case 6 since the opening thereof is closed by the press members 14 and 15;
- the press members 14 and 15 are-withdrawn and the air-blowing tube is removed, and a supply tube 18 is inserted into the bag so that a predetermined amount of a flowable materialsuch as milk or fruit juice is introduced therein as shown in FIG. 5.
- suitable methods other than aforementioned air,- blowing method can be used to expand the bag.
- the supply tube 18 is removed and the opening is sealed, for instance, by apair of heat-press members 19 and20 as shown in FIG. 6.
- the opening is kept in the two layer state, and therefore thesealing is effected in the two layer state, too. Therefore, when the heat-press members l9 and 20 are applied together to the opening, there is no fold held between the outer films, and'thus there is no stepped point. Therefore blow holes are not generated even if the inside of the opening is wetted with the flowable material. In this way a' very perfect scaling is effected in accordance with this invention.
- thermoplastic materials for the folded packaging material of this invention include polyolefin such as polyethylene, polypropylene, etc., polyvinyl chloride and paper both surfaces of which are coated with polyethylene, etc.
- the roof-shaped top of the package is sealedprior to introduction'of a flowable material. Therefore the sealing of the top can'be perfectly effected although there are inward folds on both sides held between the outer films, since there is no flowable material sticking to the inside of the opening. Also, the bottom of the package canbe perfectly sealed as mentioned above. I j
- the package of this invention has a fiat bottom, it stably stands by itself, and therefore it is very conve nient for storage and transportation;
- polyethylene for instance is shown at 34.
- the tubular thereof reach the upper end 22 of the case 6, the wings 25 and 26 are turned inward by means of a pair of plungers 31 and 32 so as to bend the now upwardly extending triangular ears 23 and 24 inward as shown in FIG. 9.
- the ears may be bonded to the flat bottom by spot heat sealing or area heat sealing, or by the aid of an adhesive.
- the triangular ears can remain extending outward if it is not inconvenient in storage or transportation.
- the guide body 37 is a long I-shape section body (Refer to FIGS. 13 to 16) the upper and lower ends 38 and 39 of which are gradually reduced in thickness and width. That is, the guide body has grooves on both sides and on the front (facing the film supply roller 34) surface at lower middle position a recess 40 is provided.
- the flattened tubular film 33 drawn out of the supply roller 34 isled to clothe the guide body 37 therewith and is passed upward.
- the guide body is held by a pair of rollers 41 and 42 on the front and back at the lower position, by a pair of rollers 43 and44 on both sides at the middle position, and by a pair of rollers 45 and 46 at the upper position.
- the rollers support the clothing film pressing it toward the guide body.
- a cutting edge 47 which is intermittenly protruded so as to give a cut in the passing tubular film. This cut becomes a sucking hole 4 in the finished package.
- a supply roller 48 for a sealing film (aluminium foil laminated with a polyethylene film on the back side, for instance) is provided above the cutting edge 47.
- roller 49 By means of roller 49, the sealing film 5 is drawn out by the length necessary to seal the sucking hole of the tubular film 33, and sealed thereupon when the hole comes to a predetermined position-For this purpose a heat-press member 50 is provided at the position, and the sealing film is pressed upon the cut hole of the tubular film and is cut off by means of a cutting knife 51 at a suitable position.
- a pair of guide plates 54 and 55 are provided, which fold inward the side'surfaces of the up-traveling tubular film into the grooves 52 and 53 provided on both sides of the guide body 37. Thereafter the tubular film 33 leaves the guide body 37 and is pressed flat by means of a pair of rollers 56 and 57, and thus the tubular film is formed into a flat folded tubular film 1 having inwardly folded portions as shown in H6. 1.
- the thus formed folded tubular film is heat-sealed by means of a pair of heat press members 2 and 3 which intermittently nip the tubular film.
- the sealed tubular film is then sent to a cutter 60 by means of a pair of rollers 58 and 59 and is snipped off at the position immediately below the seal by means of a cutter 60 which is intermittently operated.
- member 62 is a supporting roller provided against the heat-press 50.
