Abstract

The present invention relates to a kind of polybag and plastic bag rolls, and wherein polybag includes integrally formed bag body and handle, and the bottom of the bag body and the top of handle are waveform.Compared with prior art, junction between polybag and polybag is set waveform by the present invention, more laborsaving when shutting down polybag compared to current by connection buckle connection type, and experience is more preferable, more comfortably.

Description

Polybag and plastic bag roll

Technical field

The present invention relates to a kind of polybags, more particularly, to a kind of polybag and plastic bag roll.

Background technique

Although polybag can bring white pollution, the excellent performance of polybag results in that there is presently no replace well Dai Pin, polybag also have extremely strong intensity while light, this makes any to attempt complete substituted for plastic in daily life The competing product of bag all prove definitely inferior.

In fact, it is only necessary to which the reusability for improving polybag is presently to solve the most effective means of polybag, such as Fruit needs to improve the reusability of polybag, and the quality for improving polybag is particularly important.

Currently, surpassing in field in quotient, it is specified that necessary provide the mode of polybag using paid, so even be using nothing People, which receives, must also solve the charging problem of polybag under scene, currently, the polybag used by shop-assistant generally uses two kinds Mode assembles, and one is rollings, and one is stacked, the typically no handles of the former polybag, although have the advantages that it is highdensity, But because not having the apparent user of handle that can seldom select to reuse, and the latter obviously cannot carry out extraction control well, And usage experience is also bad.

Summary of the invention

It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of polybag and plastics Bag volume.

The purpose of the present invention can be achieved through the following technical solutions:

A kind of collapsible plastic bag, the polybag include integrally formed bag body and handle, the bottom of the bag body and are mentioned The top of hand is waveform.

The waveform is SIN function.

Described wavy is divided into 0.5~2.5 millimeter.

Described wavy is divided into 1 millimeter.

The polybag fold latter two handle section width and at least pocket portion width 1/5th.

A kind of plastic bag roll, which is successively joined end to end by multiple folded polybags and coiling forms, institute Stating polybag includes integrally formed bag body and handle, and the bottom of bag body and the top of handle are waveform.

The waveform is SIN function.

Described wavy is divided into 0.5~2.5 millimeter.

Described wavy is divided into 1 millimeter.

Compared with prior art, the invention has the following advantages:

1) waveform is set by junction between polybag and polybag, passes through connection buckle connection side compared to current Formula, more laborsaving when shutting down polybag, experience is more preferable, more comfortably.

2) error rate when shutting down polybag is lower, reduces artificial customer service intervention number.

Specific embodiment

The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to Following embodiments.

Be as shown in Figure 1 the polybag of traditional stacked, junction 101 is arranged in the upper limb of bag body 1, junction pass through to Part shown in Fig. 2 is fixed on certain, and the circular hole in Fig. 2 is fixation hole.

As shown in Figure 3 and Figure 4, inventor is directed to the deficiency of traditional coiled polybag, and design obtains the modeling of certain remodeling rolling Material bag, junction are connected generally by connection section, have done individual stretch processing to show more for connection section in Fig. 4 Add obviously, this processing can process to obtain by the grilling as shown in Figure 5 being made of pressing, naturally it is also possible to pass through other Mode obtains, and the lines of universal junction are flat, this simple modifications for existing rolling polybag, although solution Certainly traditional coiled polybag does not have the problem of 2 part of handle, but inventor is still unsatisfactory for this improvement, because due to junction Roll up relative to conventional plastic bag shorter, can not accomplish without any letup when tearing, and rise it is very laborious when tearing, and due to increasing handle 2 parts lead to tear a polybag and need to undergo two to rise tearing across journey, a feature being worth on mechanics, compared to biography The plastic bag roll of system is torn difficulty and is greatly improved, and causes user experience bad.

Above-mentioned improvement there are aiming at the problem that, invention redesigned a kind of collapsible plastic bag, the polybag include one Then as shown in Figure 6 and Figure 7 the top design of the bottom of bag body 1 and handle 2 is wave by body formed bag body 1 and handle 2 Shape.

As shown in figure 8, waveform is SIN function, it is preferred that wavy is divided into 0.5~2.5 millimeter, is preferably 1 millimeter.In addition, in order to obtain better experience, polybag folds the width for flattening latter two 2 part of handle and at least bag body / 5th of 1 partial width.

Using the polybag of redesign, be prepared by multiple folded polybags successively join end to end and coiling and At plastic bag roll carried out on-the-spot test to verify the advantage of the application structure, to the plastic bag roll of the application and simple Follow-on plastic bag roll compares, test process be the same time two self-checkout channels arranged side by side of same shops into Row, continues two hours, test result is as shown in table 1

Table 1

Junction shape	Lump sum user volume	Tear the number of stoppages	Abandon polybag number
				It is straight	40	10	1
Waveform	39	0	0

As shown in table 1, in the case where lump sum user volume data are equal, wavy plastic bag roll is torn in user The number of stoppages significantly reduces when pulling, therefore causes to abandon the number of self-service purchase polybag to be impatient and also significantly drop It is low.

It more laborsaving can be described below for waveform plastic bag roll.

For the plastic bag roll conventional without handle 2, due to there is no hollow space, as long as opening first when tearing A openning, subsequent tears and will more facilitate, and for the polybag of the simple modifications type provided at the beginning in embodiment Volume, due to being hollow space between junction, (common people can select the right of first tearing after the handle 2 for tearing one side Handle 2), if not changing grip locations, the conducting path of power can cause efficiency to reduce because middle control part does not connect.

And for wavy junction, since waveform is periodically arranged, polybag also can the period during tearing Property swing, just can use periodically swing energy, to achieve the effect that more laborsaving, found after tested, 1 millimeter The waveform effect at interval is best.
