Abstract
The utility model relates to a novel polypropylene combination cover. The novel polypropylene combination cover comprises an outer polypropylene cover, an inner polypropylene cover, a polyisoprene gasket and a hanging ring, wherein the inner polypropylene cover is arranged in the outer polypropylene cover. The inner polypropylene cover is provided with a pinhole, and a sealing film layer adheres to the top of the pinhole. The hanging ring is connected to the top of the outer polypropylene cover. The polyisoprene gasket is arranged between the hanging ring and the inner polypropylene cover. A plurality of O-shaped rings are arranged between the inner side surface of the outer polypropylene cover and the outer side surface of the inner polypropylene cover. The novel polypropylene combination cover has the advantages of being simple in structure, convenient to use and good in sealing performance, and does not generate inner cover fragments easily.
Description
Technical field
This utility model relates to a kind of lid, is specifically related to a kind of Novel polypropylene composite cover, belongs to field of packaging material.
Background technology
Infusion bottle adopts polypropylene combination cover to seal conventionally.The polypropylene combination cover of prior art is comprised of three parts such as inner cap, enclosing cover and pads conventionally, it is when opening, first need enclosing cover to turn on, realize transfusion needle-penetration is crossed to inner cap, easily like this make the chip that inner cap drops infiltrate medicine and pollute medicine; Meanwhile, existing polypropylene combination cover also exists poorly sealed, uses many defects such as trouble.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of Novel polypropylene composite cover, to overcome described defect of the prior art.
Utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of simple in structure, good airproof performance and is difficult for producing the Novel polypropylene composite cover of inner cap chip.
For achieving the above object, the technical scheme that this utility model is taked is: a kind of Novel polypropylene composite cover, and it comprises polypropylene enclosing cover, polypropylene inner cap, polyisoprene gasket and suspension ring; Wherein, be covered in polypropylene enclosing cover in described polypropylene, cover and be provided with a pin hole in this polypropylene, the top of this pin hole is pasted with one deck sealing rete; Described suspension ring are connected in the top of polypropylene enclosing cover; Described polyisoprene gasket is arranged between suspension ring, polypropylene inner cap; Between the medial surface of described polypropylene enclosing cover and the lateral surface of polypropylene inner cap, be provided with some O type circles.
Novel polypropylene composite cover of the present utility model is further set to: described sealing rete is aluminium foil layer.
Compared with prior art, the utlity model has following beneficial effect: Novel polypropylene composite cover of the present utility model has simple in structure, easy to use, the difficult plurality of advantages such as inner cap chip and good airproof performance that produce.
Accompanying drawing explanation
Fig. 1 is the sectional drawing of Novel polypropylene composite cover of the present utility model.
The specific embodiment
Refer to shown in Figure of description 1, this utility model is a kind of Novel polypropylene composite cover, and it is assembled by several parts such as polypropylene enclosing cover 1, polypropylene inner cap 2, polyisoprene gasket 3 and suspension ring 4.
Wherein, described polypropylene inner cap 2 is located in polypropylene enclosing cover 1, and is provided with some O type circles 7 between the medial surface of described polypropylene enclosing cover 1 and the lateral surface of polypropylene inner cap 2, thereby strengthens the sealing of this composite cover.
In this polypropylene inner cap 2, be provided with a pin hole 5.By this pin hole 5 is set, transfusion needle can directly insert without puncturing polypropylene inner cap 2, can not make polypropylene inner cap 2 produce chip and pollute medicine.In the top of this pin hole 5, be pasted with one deck sealing rete 6, this sealing rete 6 is specially aluminium foil layer, and it is for shutoff pin hole 5.
Described suspension ring 4 are connected in the top of polypropylene enclosing cover 1, and it can come off from described polypropylene enclosing cover 1, thereby this composite cover is opened.
Described polyisoprene gasket 3 is arranged between suspension ring 4, polypropylene inner cap 2, and it can increase the bond strength of this composite cover.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation within all spirit in this creation and principle.
