Abstract
The utility model relates to an anti-degaussing bag that comprises an external surface layer, a middle metal layer and an internal liner. For an ordinary handbag, a satchel, a backpack and other bags, a tinfoil or a metal sheet is arranged between the liner and the surface layer of the bag, so as to form a closed electromagnetic isolating cavity. In order to prevent a mobile phone from being interfered in the bag, a pocket can be sewn in the backpack and the bag; the periphery of the pocket is provided with a metal layer; other parts of the pocket are not provided with the metal layer; objects of the category of magnetic cards are arranged in the pocket; the mobile phone is arranged in the bag; thus the magnetic cards can be prevented from degaussing; and the mobile phone can receive signals. The anti-degaussing bag has the advantages of simple structure and easily available manufacturing materials, and adopts the principle of electrostatic shielding so as to achieve the excellent anti-degaussing effect.
Description
1, technical field:
The utility model relates to a kind of anti-demagnetization bag.
2, background technology:
Fast development along with science and technology; mobile phone and magnetic card spread among the daily life already; people carry magnetic card and mobile phone usually simultaneously; especially women; through regular meeting two things are placed in the satchel; because mobile phone is in the reception that does not stop or sends high electromagnetic wave signal state, and the tape segment to various magnetic cards that high electromagnetic wave signal can not stop carries out electromagnetic effect, just can cause the magnetic card demagnetization in the course of time and can't use.
3, summary of the invention:
The purpose of this utility model is to propose a kind of anti-demagnetization bag that can effectively prevent the magnetic card demagnetization.
The purpose of this utility model is achieved in that a kind of anti-demagnetization bag, and it is to be made by the top layer of outside, metallic intermediate layer layer and inner liner.Place mat has masking foil or other sheet metals between various bags such as common handbag, satchel, knapsack, the bag liner of class and extexine, for preventing that mobile phone from putting into bag, bag can't picked up signal, can in bag, bag, make bag flatly, metal level is set around this pocket, magnetic card class article are put into this bag, mobile phone is placed in the bag, can prevent the magnetic card demagnetization like this, but mobile phone received signal again simultaneously.
This anti-demagnetization nested structure is easy, and manufacturing materials is easy to obtain, and utilizes the electrostatic screen principle, can obtain well anti-erasure effect.
4, description of drawings:
Concrete structure of the present utility model is provided by following drawings and Examples:
Fig. 1 is anti-demagnetization bag constructions schematic diagram;
Fig. 2 is anti-demagnetization nested structure schematic diagram.
Legend: 1, top layer, 2, liner, 3, metal level, 4, magnetic card.
5, embodiment:
Embodiment 1: as shown in Figure 1, a kind of anti-demagnetization bag, it is to be made by the top layer 1 of outside, metallic intermediate layer layer 3 and inner liner 2.Place mat masking foil or other sheet metals between various bags such as common handbag, satchel, knapsack, the bag liner 2 of class and top layer 1, form the electromagnetic isolation cavity of a sealing, just can utilize the electrostatic screen principle, prevent that effectively the high electromagnetic wave of mobile phone from carrying out demagnetization to magnetic card 4.
Embodiment 2: in embodiment 1, if will lay metal level 3 around bag or the bag, then mobile phone is put into the back and just can't be received and send signal, high electromagnetic wave just can't produce, but the master can be because can't received signal and can't receive calls with opportunity, for preventing this from occurring, can in bag or bag, make a tiny pocket, metal level 3 is set around this tiny pocket, and the bag or wrap other parts and do not establish metal level 3, mobile phone is placed in the bag, magnetic card 4 class article are put into aforementioned tiny pocket, can prevent magnetic card 4 demagnetizations like this, but mobile phone received signal again.
Embodiment 3: as shown in Figure 2, anti-demagnetization bag is according to the electrostatic screen principle, utilizes metal level 3 to prevent that the high electromagnetic wave of mobile phone from carrying out demagnetization to magnetic card 4.Utilize this principle also can make anti-demagnetization cover, it is to be made of top layer 1 and metal level 3, and it makes the uncovered cavity cover of an end by plastics or other soft prepared materials, on this cavity cover inwall or paste or be suppressed with metal level 3, at ordinary times magnetic card 4 is put into this cover and just can.
Claims (3)
1, a kind of anti-demagnetization bag, it is to be made by the top layer of outside, metallic intermediate layer layer and inner liner, it is characterized in that: place mat has masking foil or other sheet metals between various bags such as common handbag, satchel, knapsack, the bag liner of class and top layer, forms the electromagnetic isolation cavity of a sealing.
2, anti-demagnetization bag as claimed in claim 1 is characterized in that: in bag or bag, makes a tiny pocket, metal level is set around this tiny pocket, and bag or wrap other parts and do not establish metal level.
3, a kind of anti-demagnetization bag, be according to the electrostatic screen principle, utilize metal level to prevent that the high electromagnetic wave of mobile phone from carrying out demagnetization to magnetic card, utilize this principle also can make anti-demagnetization cover, it is characterized in that: anti-demagnetization cover is to be made of top layer and metal level, make the uncovered cavity cover of an end by plastics or other soft prepared materials, this cavity overlaps on inwall or pastes or be suppressed with metal level.
