Description

A kind of high barrier PE plastic bottles

Technical field

It the utility model is related to a kind of plastic bottle, and in particular to a kind of high barrier PE plastic bottles.

Background technology

Polythene material is widely used in the packaging of multiple product at present.For biological similar drug, the quality guarantee period Relatively long, infiltration to moisture in air has higher requirement again during storage, once by the moisture contamination in air, then Irreversible influence can be caused on its property of medicine, so as to bring serious loss, used vinyon bottle is at present Single layer structure, it is unable to reach the requirement of Key works Drug packing.

In view of the defects of above-mentioned existing polythene material plastic bottle is present, the present inventor is based on being engaged in such product design Manufacture abundant for many years practical experience and professional knowledge, and coordinate the utilization of scientific principle, actively it is subject to research and innovation, to found one Kind novel high-barrier PE plastic bottles, make it have more practicality.

Utility model content

Main purpose of the present utility model is, the defects of overcoming existing polythene material plastic bottle to exist, and provides A kind of novel high-barrier PE plastic bottles, the moisture in air can be effectively obstructed, thus more suitable for practicality, and there is industry On value.

The purpose of this utility model and solves its technical problem using following technical scheme to realize.

A kind of high barrier PE plastic bottles, including bottleneck, shoulder, body and bottom of bottle, in addition to be arranged on interior in body Courage, is provided with cavity between the body and inner bag, the body and the inner bag are made of PE plastics, set in the cavity Drier bag is equipped with,

The wall thickness of the body is 2-3 times of the inner bag wall thickness；

The bottleneck of the bottleneck of the body and the inner bag is fixed together, and the bottom of the inner bag, which rides upon, to be located at In bottom of bottle below the body.

Further, the body is that spiral is connected with bottom of bottle.

Further, it is circumferentially provided with anti-skidding grip part in the middle part of the body outer wall.

Further, the anti-skidding grip part upper surface is provided with protruding block or fine thread.

Further, soft rubber pad is provided between the bottom of the inner bag and bottom of bottle.

Further, the soft rubber pad is fixedly installed on the bottom of the inner bag.

Further, the thickness of the bottom of bottle is 2-5mm.

Using above-mentioned technical proposal, following technique effect can be obtained：

1）, double layer design PE material plastic bottles, the steam in air has effectively been obstructed to a certain extent, in two layers of PE Drier is placed between material layer so that the steam into body is further absorbed, and moisture sorption effect is notable, barrier compared with It is high；

2）, when the humidity in air it is larger, when drier moisture absorption is more, in order to lasting holding moisture sorption effect, therefore Body is connected with bottom of bottle using spiral, facilitates the replacing of cavity internal desiccant；

3）, body is provided with anti-skidding grip part, convenient crawl；

4）, between the bottom of bottle of body and the bottom of bottle of inner bag be provided with soft rubber, can further increase the bottom of bottle of body with it is interior The connection of the bottom of courage, in case inner bag shrinks and its bottom occurs without destruction caused by stress layer.

Brief description of the drawings

Fig. 1 is the structural representation of high barrier PE plastic bottles of the present utility model.

The implication marked in accompanying drawing is as follows：

1：Bottleneck；2：Shoulder；3：Body；31：Inner bag；32：Cavity：33：Anti-skidding grip part；4：Bottom of bottle.

Embodiment

Further to illustrate that the utility model is to reach the technological means and effect that predetermined purpose of utility model taken, To according to the utility model proposes high barrier PE plastic bottles its embodiments, feature and its effect, describe in detail such as Afterwards.

As shown in figure 1, the utility model discloses a kind of high barrier PE plastic bottles, including bottleneck 1, shoulder 2, body 3 With bottom of bottle 4, in addition to the inner bag 31 being arranged in body, cavity 32, body 3 and inner bag 31 are provided between body 3 and inner bag 31 It is made of PE plastics.

In order to further increase the ability of the steam in the barrier air of plastic bottle, drier is placed with cavity 32 Bag.Preferable drier is silica-gel desiccant or calcium chloride drier.Drier is solid, can be directly placed in cavity 32, Or it is distributed into pouch with polybag and is placed into cavity 32.And in order to the moisture absorption after drier moisture absorption reaches to a certain degree Effect is timely changed when reducing, and to keep the moisture sorption effect of drier bag, therefore body 3 is that spiral is connected with bottom of bottle 4, Bottom of bottle 4 is turned on during replacing, the replacing of agent bag is dried.

And the wall thickness of body 3 is 2-3 times of the wall thickness of inner bag 31, the bottleneck of the bottleneck and inner bag 31 of body 3 is fixedly connected on Together, the bottom of inner bag 31 rides upon bottom of bottle 4, is provided with soft rubber pad between bottom of bottle 4 and the bottom of inner bag 31, soft rubber is fixed It is arranged on the bottom of inner bag 31.

In order to increase the comfort level that plastic bottle uses, anti-skidding grip part 33 is circumferentially provided with the middle part of the outer wall of body 3.It is excellent The anti-skidding grip part 33 of choosing is provided with protruding block or fine thread.

The thickness of bottom of bottle 4 is 2-5mm, can further increase the endurance of bottom of bottle 4.

It is described above, only it is preferred embodiment of the present utility model, not the utility model is made any formal Limitation, although the utility model is disclosed above with preferred embodiment, but be not limited to the utility model, it is any ripe Professional and technical personnel is known, is not being departed from the range of technical solutions of the utility model, when in the technology using the disclosure above Hold the equivalent embodiment made a little change or be modified to equivalent variations, as long as being without departing from technical solutions of the utility model Hold, any simple modification, equivalent change and modification made according to the technical essence of the utility model to above example, still Belong in the range of technical solutions of the utility model.
