Abstract

The invention discloses a supermarket rolling bag with open guiding ports. Two ends of a bag opening are provided with guiding ports along a tear line, and thus a thin-film bag can be more easily torn down; the guiding ports are through holes, when the bag opening needs to be opened, the edges of the guiding ports can be respectively held from two sides of the thin-film bag by thumbs, index fingers or middle fingers, finger pulps of two fingers can be connected, entwisting in reverse directions can be then carried out, and thus the thin-film bag can be more easily opened.

Description

Band is opened the supermarket bag on roll of guide port

Technical field

The present invention relates to the supermarket bag on roll that a kind of band of easily opening is opened guide port, belong to the optimization technique of bag film.

Background technology

Supermarket all can be used the scattered commodity such as fresh, the thin dish of bag film packing conventionally.Therefore these bag films are all to join end to end to be rolled into spool conventionally, are again bag on roll, pull out a bag film and tear along separation line, then twist open sack article are put into pointing during use from spool.But when twisting open sack with finger, usually occur the situation that sack cannot be opened, some people can be stained with the friction force that a little mouthfuls of hands increase finger, so both unbecoming also unhygienic; Some people can abandon being difficult in hand the bag film of opening, and again pulls one and tries, so just causes unnecessary waste.

Therefore, need to find a kind of supermarket bag film of easily opening.

Summary of the invention

The object of this invention is to provide the supermarket bag on roll that a kind of band of easily opening is opened guide port.

Technical scheme of the present invention is: band is opened the supermarket bag on roll of guide port, by the identical bag film 1 of a plurality of sizes, joined end to end to twist in rotating shaft and form, by the identical bag film 1 of a plurality of shape sizes, join end to end and form, described bag film twists in rotating shaft, one end that bag film 1 is provided with sealing line 2 is the bag end, the one end that is provided with tear line 3 is sack, at the two ends of tear line 3, a guide port 4 is set respectively, during use, along tear line, shut down after bag film, with thumb, forefinger or middle finger pinch guide port 4 from two walls of bag film respectively, the finger belly of two fingers is partly joined, one twist with the fingers in the opposite direction again, utilize the displacement of the double-layer films that forms bag film, double-layer films is separately opened to bag film in the opposite direction from the notching edge of guide port 4.

Described guide port 4 is positioned at one end of tear line 3 one side pocket mouths.

Described guide port 4 be shaped as triangle or fan-shaped.

beneficial effect

1, band is opened the supermarket bag on roll of guide port, along tear line, guide port is set, the bag film of more easily tearing at sack two ends; Guide port is through hole, in the time of opening sack, with thumb, forefinger or middle finger, pinches respectively the edge of guide port from bag film both sides, and the finger belly of two fingers is joined, then one twists with the fingers in the opposite direction, just can open more like a cork bag film.

Accompanying drawing explanation

Fig. 1 is bag film volume schematic diagram of the present invention;

Fig. 2 is main TV structure schematic diagram of the present invention.

The specific embodiment

As Fig. 1, shown in Fig. 2, band is opened the supermarket bag on roll of guide port, by the identical bag film 1 of a plurality of sizes, joined end to end to twist in rotating shaft and form, by the identical bag film 1 of a plurality of shape sizes, join end to end and form, described bag film twists in rotating shaft, one end that bag film 1 is provided with sealing line 2 is the bag end, the one end that is provided with tear line 3 is sack, at the two ends of tear line 3, a guide port 4 is set respectively, during use, along tear line, shut down after bag film, with thumb, forefinger or middle finger pinch guide port 4 from two walls of bag film respectively, the finger belly of two fingers is partly joined, one twist with the fingers in the opposite direction again, utilize the displacement of the double-layer films that forms bag film, double-layer films is separately opened to bag film in the opposite direction from the notching edge of guide port 4.

Band is opened the supermarket bag on roll of guide port, at sack two ends, along tear line, guide port is set, and during use, with hand, catches the bag film that is positioned at end to exert oneself, and because tear line two ends are provided with guide port, bag film is easy to tear along tear line.

Tear after bag film, because guide port is through hole, open sack, only need to from bag film both sides, pinch respectively the edge of guide port with thumb, forefinger or middle finger, the finger belly of two fingers is joined, then one twist with the fingers in the opposite direction, just can open more like a cork bag film.

As shown in Figure 1, due to 4 pairs of guide ports being set at the bottom of bag, to open plastic bag inoperative, and therefore, a preferred embodiment of the present invention is that 4 of guide ports are located at sack one end.

Described guide port 4 be shaped as triangle or fan-shaped, i.e. the two ends unfilled corner of sack.Article two, square edge lays respectively at tear line and bag film side, one side bag with it be straight flange or arc.

The present invention is simple, easily produces, and only need to when producing bag film, utilize machine to open guide port 4 at tearing port 3 two ends, and original bag film production procedure and technique are not needed to make large change.

Above-described embodiment is only for interpretation purposes of the present invention, and is not limitation of the present invention, and those skilled in the art, in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
