Abstract
The utility model relates to a safe bottle cover of an anti-expanding bottle, a breathing hole is formed in the middle of the bottle cover, and a micro-pore ePTFE (expanded polytetrafluoroethylene) membrane is mounted at the breathing hole inside the bottle cover in a sealing manner. As the micro-pore ePTFE membrane is mounted at the breathing hole through thermal polymerization and has the properties of ventilation and imperviousness, the inside and outside pressure of a container can be efficiently balanced, so as to prevent a bottle from expanding and guarantee the safety; moreover, the ePTFE membrane has the characteristic of preventing liquid medicine corrosion, so that the service life of the bottle cover can be efficiently prolonged.
Description
Technical field
The utility model belongs to the packing container field, relates to container closure, especially a kind of resistant closure of the anti-bottle that rises.
Background technology
Be filled with the container of soup for some, in storage process, in the transportation or when light irradiation, temperature build-up, soup unavoidably can produce gas, and as peracetic acid soln etc., a bottle phenomenon easily promptly rises.If it is too high that the soup pressure in the untimely solution, container continues, not only be difficult to open bottle cap, even the bottle explosion accident can take place, jeopardize personal safety as well as the property safety.Therefore, solving bottle problem that rises of soup, store for safety in production and transportation, is crucial.
At present, solve bottle problem that rises of above-mentioned soup, the mode that mainly adopts special device to transport and store, as in seal-off pressure container traffic or storage etc., but cost is higher, uses inconvenient.
By retrieval, do not find the publication document relevant with the utility model application yet.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of resistant closure of simple in structure, safety the is good anti-bottle that rises is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of resistant closure of the anti-bottle that rises is shaped on a breather hole in the middle part of bottle cap, and the breather hole position in bottle cap encapsulates an ePTFE micropore eptfe film.
And described ePTFE micropore eptfe film and bottle cap thermal polymerization install.
Advantage of the present utility model and beneficial effect are:
This bottle cap is shaped on an air extractor vent at the middle part, the ePTFE micropore eptfe film of the air extractor vent position hot polymerization unification permeable watertight in bottle cap, this polytetrafluoroethylene film permeable watertight, but the external and internal pressure of active balance container thus, prevent the bottle that rises, ensure safety; In addition, polytetrafluoroethylene film also has the characteristics of anti-soup corrosion, the service life that can effectively improve bottle cap.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is that the A-A of Fig. 1 is to cross-sectional view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by specific embodiment, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of resistant closure of the anti-bottle that rises is to be shaped on a breather hole 2 in the middle part of bottle cap 1, and this ventilative hole size is set according to the difference of institute's splendid attire soup in the container; Breather hole position in bottle cap and breather hole coaxial packaging one ePTFE micropore eptfe film 3; Because bottle cap adopts plastic production, so this film can adopt thermal polymerization mode and bottle cap to install.
Because ePTFE micropore eptfe film has permeable watertight, erosion resisting characteristics, therefore can effectively avoid the air pressure in the container to assemble, prevent the bottle that rises.
Claims (2)
1. the resistant closure of the anti-bottle that rises, it is characterized in that: be shaped on a breather hole in the middle part of bottle cap, the breather hole position in bottle cap encapsulates an ePTFE micropore eptfe film.
2. the resistant closure of the anti-bottle that rises according to claim 1, it is characterized in that: described ePTFE micropore eptfe film and bottle cap thermal polymerization install.
