Description

Technical Field

[0001] This invention relates to a mobile battery pouch for safely storing a mobile battery.

Background Art

[0002] In recent years, with the spread of mobile terminals such as smartphones, the opportunity to carry a mobile battery as a backup power source has been increasing. Since a mobile battery incorporates a lithium-ion battery, there is a risk that accidents accompanied by abnormal heat generation, ignition, or even explosion may occur due to factors such as impact from dropping, overcharging, or internal short circuit. Against this background, in order to safely carry a mobile battery, a storage pouch using a flame-retardant fabric obtained by applying a silicon coating to a glass fiber cloth has been proposed.

[0003] Generally, although a silicon-coated fabric has excellent heat resistance and flame retardancy, it has the characteristic that the coating film does not adhere sufficiently with a general printing method using ink. Therefore, even when a logo or identification display of a product is applied, there is a practical problem that the printing is likely to peel off during use. In addition, many flame-retardant pouches have a unique smooth or uniform texture, and it has been difficult to instantly identify the orientation and front and back of the pouch only by the sense of fingertips without relying on vision inside a bag, in a dark place, or in an emergency. Furthermore, the vicinity of the opening of the pouch is a part that repeatedly rubs violently against the user's hand and fingers due to frequent insertion and removal of the stored item, so there remains a durability problem that the silicon coating at the opening end gradually wears and is likely to peel off due to this friction.

Summary of the Invention

Problems to be Solved by the Invention

[0004] This invention was made to solve the conventional problems described above. The purpose of this invention is to provide a mobile battery pouch that dramatically improves the adhesion of markings to silicone-coated fabric by using a material of the same quality as the main body material for the markings, and enables tactile identification through its three-dimensional structure. Furthermore, by adopting a structure that reduces friction at the opening, the invention aims to provide a highly durable mobile battery pouch in which the silicone coating is less likely to peel off even with repeated insertion and removal. [Means for solving the problem]

[0005] The mobile battery pouch according to this invention comprises a pouch body that is shaped like a bag for storing a mobile battery and has an opening at its upper end for inserting and removing the mobile battery. The pouch body is made of a flame-retardant fabric in which a silicone coating is applied to the surface of a fiberglass cloth that serves as the base material. An identification mark is provided on the surface of the pouch body. This identification mark is characterized by being formed in a raised, three-dimensional shape that protrudes outward from the surface of the pouch body by silk printing using silicone rubber.

[0006] Furthermore, in one aspect of this invention, it is desirable that the portion forming the inner surface of the pouch body be coated with aluminum foil to enhance heat shielding and heat insulation. In addition, a zipper is provided at the opening of the pouch body, and a belt-shaped member is attached to the surface of the pouch body at a position adjacent to the zipper at the end on the opening side. The belt-shaped member can be attached in various ways, but it is preferably sewn to the surface of the pouch body. Sewing provides a more heat-resistant attachment than, for example, attachment with adhesive. Furthermore, it is preferable that the belt-shaped member be attached on top of the silicone-coated surface of the main body. This makes the structure even more wear-resistant as the silicone coating continues from the back surface of the belt-shaped member. In addition, it is preferable that the identification display portion is formed in the shape of a specific character. [Effects of the Invention]

[0007] According to this invention, since the identification marking portion is formed of silicone rubber, it has extremely high affinity with the coating on the main body surface, resulting in a significantly improved resistance to peeling compared to conventional ink printing. Furthermore, by using silicone rubber for the identification marking portion, the heat resistance of the identification marking portion can be made higher compared to conventional ink, thus reducing the risk of the identification marking portion located on the outermost surface of the pouch according to this invention igniting first.

[0008] Furthermore, because the identification markings are formed as a raised, three-dimensional shape, users can reliably recognize the front, back, and orientation of the pouch using only their fingertips, achieving excellent usability by allowing them to insert and remove the mobile battery without accidental operation, even in dark places or inside a bag. In particular, by adopting a specific character shape, a complex raised and recessed shape is formed, making the identification function even clearer.

[0009] Furthermore, by sewing a belt-like component to the area adjacent to the zipper near the opening of the pouch, where friction is most likely to occur, it is possible to effectively prevent the user's fingers from directly contacting and rubbing the silicone-coated surface when inserting or removing items. This has the technical advantage of preventing the silicone coating around the opening from peeling off even after long-term use, thus maintaining the product's flame-retardant properties and appearance. [Brief explanation of the drawing]

[0010] [Figure 1] This is a perspective view showing a mobile battery pouch according to one embodiment of the present invention. [Figure 2] This is a front view showing the configuration of the mobile battery pouch. [Figure 3] This is a rear view showing the configuration of the mobile battery pouch. [Figure 4] This is an enlarged end view along line AA in Figure 2. [Modes for carrying out the invention]

[0011] Hereinafter, one embodiment of the mobile battery pouch according to the present invention will be described in detail with reference to the drawings. As shown in Figures 1 and 2, the mobile battery pouch 1 of this embodiment has a rectangular bag-like shape overall, and is configured for the purpose of safely storing and carrying a mobile battery MB inside.

[0012] The material that makes up the pouch body 2 is a flame-retardant fabric in which a silicone coating 4 is applied to the surface of a fiberglass cloth 5 that serves as the base material. This prevents the pouch itself from burning even if the contents generate heat or ignite, thus minimizing the spread of fire.

[0013] Figure 4 shows the end face structure obtained by cutting the opening 7 of the pouch body 2 in Figure 2 along the center line in the width direction, from the opening 7 toward the bottom surface. The identification display section 9, an important feature of this invention, is formed in the shape of a specific character (for example, a design resembling a panda) on the front surface of the pouch body 2, as shown in Figures 2 and 4.

[0014] This identification mark 9 is not formed by printing with ordinary ink, but by thick silk screen printing using silicone rubber of the same quality as the silicone coating 4 that makes up the outermost surface of the pouch body 2. By applying a thick layer of silicone rubber material to form a three-dimensional shape, as can be seen in the end view of Figure 4, the identification mark 9 has an end face shape that clearly protrudes outward from the surrounding fabric surface, making it possible to instantly determine that "the side with the character-shaped protrusion is the front" by touch alone.

[0015] An opening 7 is provided at the upper end of the pouch body 2, and a zipper 8 is provided to allow items to be easily inserted and removed. As shown in Figures 2 and 3, a belt-shaped member 11, which is a tape-like reinforcing material, is sewn to the surface of the pouch body 2 at the end on the opening 7 side, that is, at a position adjacent to the zipper 8.

[0016] This belt-shaped component 11 functions as a protective layer to prevent the user's hands and fingers from repeatedly rubbing against the silicone coating 4 near the opening 7 due to frequent insertion and removal of the mobile battery MB. This suppresses wear and peeling of the silicone coating 4 due to friction, maintaining flame-retardant performance and a beautiful appearance over a long period of time.

[0017] The belt-shaped member 11 is preferably attached along the opening 7. In this embodiment, the belt-shaped member 11 can be attached so as to encircle the circumferential surface of the pouch body 1, thereby protecting the entire portion adjacent to the opening 7.

[0018] On the part that forms the inner surface 2a of the pouch body 2, an aluminum foil coating 6 is applied on one side. This aluminum foil coating 6 functions as a non-combustible material, and at the same time, when the mobile battery MB generates heat, it exhibits a heat insulation and heat retention effect to retain the heat inside the pouch, playing a role in delaying heat conduction to the outside.

[0019] Also, when forming the pouch body 2, a process is adopted where each member is sewn in a turned-over state and then turned back to the front side. By having a structure where the seams are contained inside as seen in the end-face structure of FIG. 4, the resistance to flames and impacts from the outside is enhanced.
