Description

Bag on roll

Technical field

A kind of bag on roll being easily opened is the utility model is related to, belongs to the optimisation technique of bag film.

Background technology

Supermarket generally can all pack the scattered commodity such as fresh, vegetable using bag film.These bag films are generally all head and the tail It is connected and is rolled into spool, therefore be called bag on roll, a bag film is pulled out from spool and is torn along separator bar during use, then use hand Finger twists open sack and placed an article within.But when twisting open sack with finger, usually there is the situation that sack is difficult to open.

The material of bag on roll is soft, frivolous, smooth plastic foil, usually using cartridge type film is coating materials during production, Sealing line, perforated line are set in production equipment, are most post-rolled on spool.In order to facilitate use and transport, bag on roll volume is being rolled up Bag is rolled up and tensed by meeting with weight pendant pressure during on axle, ensures that bag rolls tightly reality, bag rolls tightly can reduce space-consuming in fact, beautiful See, easily transport, when in use, can in use, the sack of sack is still close on bag volume after bag on roll tail end sack is torn To ensure health, but the sack sack therefore removed is close to before and after being also, and because sack coating materials is soft, frivolous, smooth, Therefore sack not only front and rear patch is tight, and smooth frictional force is small, soft, frivolous bad control, so more difficult twisted open with hand.Cause As long as this rolls tightly real bag on roll with the bag of soft, frivolous, smooth film production can all the problem of being difficult to open opening, Be not only supermarket's bag on roll, some food-grade family expenses bag on rolls in order to ensure health also have Similar Problems.

The bag on roll that a kind of bag on roll structure being easy to open of the title of application number 201120266281.7 provides is in production Produced using film doubling, than directly with more one of the production process of tubular film production, adding cost, and the bag of bag volume Son opening does not seal all, is chronically exposed to outer unhygienic.

Supermarket's bag on roll that the title band of application number 201210275595.2 opens guide port provides guide port.Application number Bag on roll of 201320005403.6 titles with opening provides positioning port and opening, application number 201020141009.1 A kind of plastic film roll bag is claimed to provide opening.Because bag on roll is produced using tubular film, by the front and back of film Correspondence position carries out different processing, and difficulty can increase in production, increases production cost, and work is not used in actual life In the production of industry metaplasia and launch.It is to both provide extra opening that this 3 technical schemes, which also have a common feature, or even also It is required that opening is easily opened, sack contaminated possibility of the bag on roll during using and depositing on bag volume is also increased, It adds additional and be chronically exposed to outer antihygienic problem.

Although above scheme is easier to open than usually used bag on roll, all do not overcome bag surface smooth, Frictional force is small, frivolous, soft bad control these the reason for causing sack to be not easy to open, and some also sacrifices sack Sealing, causes new hygienic issues, the technical scheme also having it is high to manufacturing requirements, it is necessary to existing equipment is done compared with More transformations could produce.

The production technology of bag on roll can check on network, be exemplified below 2 and check network address：

The content of the invention

The purpose of this utility model is to provide a kind of bag on roll being easily opened, and is especially suitable for the surface of tubular film production Smooth, the front and rear bag on roll being close to.

The technical solution of the utility model is：Joined end to end the bag on roll formed by multiple bag films, each sack composition Bag on roll front portion is the anter of sack, and sack composition bag on roll back portion is rear of sack, per two adjacent bags The anter of son is connected by perforated line with tension belt, and rear per two adjacent sacks is also to pass through perforated line and tension belt phase Even, tension belt the right and left is not connected with sack, and rear and front end is connected with the sack of two neighboring sack and bottom respectively, and The width of tension belt is wider than the width of two neighboring sack each tie point in perforated line.The production material of bag on roll is plastics Film, ductility is good with elasticity, when tearing from bag volume or drag lower sack, because each tie point of perforated line is shorter, is easier to be torn Disconnected or drag disconnected, tension belt is wider, it is relative be not easy by tear fracture or drag it is disconnected, so during removing sack from bag volume, point off Each tie point of line first by tear fracture or drag it is disconnected, tension belt will not at once by tear fracture or drag it is disconnected, but the ductility due to coating materials with Elasticity is stretched deformation and thinning, when tension belt produce certain deformation and it is thinning after, sack anter and the tension belt on rear piece No longer it is close to, tension belt will be dragged disconnected by continuing to stretch tension belt, and dragging the fracture having no progeny in tension belt can tilt and produce thicker Rough hair side, and because now anter has no longer been close to two tension belts on rear piece, can separate automatically, then pass through Two tension belts are opened sack and are very easy to.Anter in bag on roll per two adjacent sacks passes through perforated line and tension belt phase Even, rear per two adjacent sacks is also to be connected by perforated line with tension belt, and the anter of each sack is with after in bag on roll Tension belt on piece is to overlap, and anter is also what is overlapped with each tie point of the perforated line on rear piece, i.e., bag on roll it is positive with The back side is completely superposed, and can facilitate excision forming of blade in processing, and machine construction can be simpler, and processing is easier, The edge of a knife shape can for changing existing bag on roll production equipment is especially only needed directly to produce, production cost is low, easily pushes away Wide production.

Preferably, tension belt is the uneven slice of width, and the most narrow place of tension belt than two neighboring sack in point off The width of each tie point is wide on line, and tension belt can be dragged disconnected at most narrow place, can wherein be dragged with restrained stretching band disconnected.

Preferably, tension belt is in the close edge of front and rear sack junction, convenient more point off of being tried one's best from one side tear fracture Line tie point.

The beneficial effects of the utility model are：The sack removed from film bag on roll can be by automatically separated Tension belt is opened, it is easier to opens, and this bag on roll storage health, easy processing, easily promote production.

Brief description of the drawings

Fig. 1 is the bag volume schematic diagram of bag on roll.

Embodiment

In Fig. 1, Fig. 2 and Fig. 3, the width of tension belt 4 each tie point in perforated line 3 than two neighboring sack 1 Width is wide, drags the sack 1 of bag volume end, and each tie point at perforated line 3 is first dragged disconnected, and now tension belt 4, which is stretched, starts to produce Raw deformation is simultaneously thinning, and the anter of sack 1 of end is gradually no longer close to the tension belt 4 on rear piece, continues to drag the sack 1 of end, The deformation of tension belt 4 is become larger, disconnected until being dragged, and sack 1 is batched down from bag.

In figs. 2 and 3, the main structure diagram of one embodiment and its partial enlarged drawing can only all see bag on roll Positive structure, because the back side of bag on roll overlaps with front, the back side is just covered by front, so the stretching at the back side Band 4 and 3 each tie point of perforated line are all invisible.

In figs. 2 and 3, tension belt 4 is the uneven slice of width, and than two, the most narrow place of tension belt 4 sack 1 exists The width of each tie point is wide in perforated line 3.

In Fig. 4, sealing line 2 turns into the bottom seal of sack 1, turns into sack at origin broken string 3, the end of tension belt 4 Fracture has tilted when sack 1 is rolled up from bag and removed and has produced rougher flash, now the anter of sack 1 and the drawing on rear piece Stretch band 4 to separate automatically, can be easier by the tension belt 4 having been separated to open sack 1.
