Abstract
The utility model relates to a kind of seal casing for preventing material from contacting with air, comprise casing, case lid and elastic caoutchouc, described casing is hinged with corresponding case lid by lotus page, described case lid is provided with for linking closely the hasp be connected with casing, it is characterized in that: the thickness of described casing is 1-2cm, the edge of opening that casing is corresponding with described case lid is provided with the groove for rabbeting described elastic caoutchouc, the width of described groove is 0.3-0.8cm; Described elastic caoutchouc lower end is connected with casing in described groove by interlocking, and the exposed part outside casing of described elastic caoutchouc is that sickle shaped has concaved.When case lid covers, exposed elastic caoutchouc outside casing is extruded and curves inwardly, thus realizes the complete hermetic state of chest, stops air and enters in case from the gap between casing and case lid.The utility model structure is simple, easy to make, with low cost, is applicable to extensively promoting.
Description
Technical field
The utility model relates to a kind of seal casing, specifically refers to a kind of seal casing for preventing material from contacting with air.
Background technology
Urethane resin as a kind of High molecular material with high strength, anti tear, the characteristic such as wear-resisting, in field widespread uses such as daily life, industrial and agricultural production, medical science.Polyurethane is met air and is easily produced chemical reaction, so liquid polyurethane, in canned packed and transported process, must reduce and contact with air.Certainly, except urethane resin, also have many needs to stop to write the material of air contact, need a seal casing that can prevent air from entering, the design of current seal casing is very ripe, but air still likely enters in case from the gap between seal casing and case lid.Therefore, the solution for above-mentioned Problems existing is research purpose of the present utility model.
Utility model content
For above-mentioned prior art Problems existing, the utility model is to provide a kind of seal casing for preventing material from contacting with air, effectively can solve above-mentioned prior art Problems existing.
The technical solution of the utility model is: a kind of seal casing for preventing material from contacting with air, comprise casing, case lid and elastic caoutchouc, described casing is hinged with corresponding case lid by lotus page, described case lid is provided with for linking closely the hasp be connected with casing, the thickness of described casing is 1-2cm, the edge of opening that casing is corresponding with described case lid is provided with the groove for rabbeting described elastic caoutchouc, the width of described groove is 0.3-0.8cm; Described elastic caoutchouc lower end is connected with casing in described groove by interlocking, and the exposed part outside casing of described elastic caoutchouc is that sickle shaped has concaved.
Further, described case lid is provided with leader.
Further, the exposed Partial Height outside casing of described elastic caoutchouc is 3-5cm.
Further, described casing can be the shape such as cuboid, cylinder.
Advantage of the present utility model: a kind of seal casing for preventing material from contacting with air, the edge of opening of casing is provided with the groove for rabbeting described elastic caoutchouc, elastic caoutchouc lower end is connected with casing in described groove by interlocking, the exposed part outside casing of described elastic caoutchouc is that sickle shaped has concaved, when case lid covers, exposed elastic caoutchouc outside casing is extruded and curves inwardly, thus realize the complete hermetic state of chest, stop air and enter in case from the gap between casing and case lid.The utility model structure is simple, easy to make, with low cost, is applicable to extensively promoting.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Now embodiment is described in further detail structure of the present utility model by reference to the accompanying drawings for the ease of it will be appreciated by those skilled in the art that:
With reference to figure 1, for the seal casing preventing material from contacting with air, comprise casing 1, case lid 2 and elastic caoutchouc 3, described casing 1 is hinged with corresponding case lid 2 by lotus page, described case lid 2 is provided with for linking closely the hasp 4 be connected with casing 1, and described case lid 2 is provided with leader 21; The thickness of described casing 1 is 1.5cm, the edge of opening that casing 1 is corresponding with described case lid 2 is provided with the groove 11 for rabbeting described elastic caoutchouc 3, and the width of described groove 11 is 0.8cm; Described elastic caoutchouc 3 lower end is connected with casing 1 in described groove 11 by interlocking, and the exposed part outside casing 1 of described elastic caoutchouc 3 is that sickle shaped has concaved, and the exposed Partial Height outside casing 1 of described elastic caoutchouc 3 is 3-5cm; Described casing 1 can be the shape such as cuboid, cylinder.
When case lid 2 covers, exposed elastic caoutchouc 3 outside casing 1 is extruded and curves inwardly, thus realizes the complete hermetic state of chest, stops air and enters in case from the gap between casing 1 and case lid 2.The utility model structure is simple, easy to make, with low cost, is applicable to extensively promoting.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
