Abstract

The utility model discloses a sealing film comprising a film and a rubber band, wherein the rubber band is an annulus which is connected end to end; the film is fixed inside the annular rubber band, and air holes are processed in the surface of the film; the film has high malleability; the structure is mainly realized through integrated design of the rubber band and the film, a rubber band deformation cover is arranged on a triangular bottleneck, and then, the rubber band is restored to fasten the film at the triangular bottleneck; four pull rings are fixed on the circumference of the rubber band; the four pull rings are distributed by taking the center of the rubber band as a symmetric center, and the included angle between by a connecting line of two centrosymmetric pull rings and a connecting line of the other two centrosymmetric pull rings is larger than 55 DEG and smaller than or equal to 90 DEG; and the main aim of designing the pull rings is to conveniently spread the rubber band.

Description

A kind of sealed membrane

Technical field

The utility model relates to the use for laboratory sealed membrane, particularly a kind of sealed membrane that carries rubber band.

Background technology

The triangular flask sealed membrane is a kind of laboratory staple, more often use when cultivating germ, it can very effective filtration dust, prevents bacterial contamination, good permeability, high temperature high voltage resistant, but often need in use to use together with common sealed membrane and bungee, film needs oneself to tear and then prepares rubber band and is tamping, and when pulling down so the general just expense of film fallen can not repeated usage, forget at which after rubber band easily puts down, cause unnecessary waste.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of

For reaching above purpose, be achieved through the following technical solutions:

A kind of sealed membrane comprises film and bungee, and bungee is end to end annular arrangement; It is inner that film is fixed in the annular arrangement bungee, and its film surface is processed with pore; The film material is the high ductibility film; This structure mainly realizes realizing that by bungee and the design of film integral type bungee deformation is nested with at the triangle bottleneck, then replys by bungee film 1 is fastened on the triangle bottle mouth position;

Be fixed with 4 draw rings on the bungee circumference; 4 draw rings distribute take the bungee center as center of symmetry, and two Central Symmetry draw ring lines with two other Central Symmetry draw ring line angle greater than 55 ° less than or equal to 90 °, by the design of draw ring, main convenient at the expansion bungee.

This experiment is novel to be improved on traditional sealed membrane, presses the high quality bungee on common double-deck sealed membrane, convenient and practical, is convenient to storage and sealing effect good, can reuse, and avoids waste.

Above-mentioned explanation is only the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification sheets, and for above and other purpose of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and the cooperation accompanying drawing, be described in detail as follows.

Description of drawings

The utility model is totally 1 width accompanying drawing, wherein:

Fig. 1 is plan structure schematic diagram of the present utility model.

In figure: 1, film, 2, bungee, 3, draw ring.

The specific embodiment

A kind of sealed membrane as shown in Figure 1 comprises film 1 and bungee 2, and bungee 2 is end to end annular arrangement; Film 1 is fixed in annular arrangement bungee 2 inside, and its film 1 surface working has pore; Film 1 material is the high ductibility film; This structure mainly realizes realizing that by bungee 2 and film 1 integral type design bungee 2 deformation are nested with at the triangle bottleneck, then replys by bungee 2 film 1 is fastened on the triangle bottle mouth position;

Be fixed with 4 draw rings 3 on bungee 2 circumference; 4 draw rings 3 distribute take bungee 2 centers as center of symmetry, and two Central Symmetry draw ring 3 lines and two other Central Symmetry draw ring 3 line angles greater than 55 ° less than or equal to 90 °, design by draw ring 3, main conveniently at expansion bungee 2, namely the user points in use and stretches into draw ring 3, outwards stretches, and then impel bungee 2 to expand, and then can be nested with at the triangle bottleneck, unclamp draw ring 3 bungees 2 and reply, film 1 is fastened on the triangle bottle mouth position;

This experiment is novel to be improved on traditional sealed membrane, presses the high quality bungee on common double-deck sealed membrane, and arranging of draw ring facilitate the user practical to the stretching of bungee expansion, and sealing effect is good, can reuse, and avoids waste.

the above, it is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet be not to limit the utility model, any those skilled in the art are not within breaking away from the technical solutions of the utility model scope, appeal when utilizing the equivalent embodiment that the technology contents that discloses is made a little change or is modified to equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
