Description

[Technical field]

[0001] This invention relates to a cover used to protect objects having a dome-shaped top lid, such as OD cans (outdoor gas cans) and similar objects. [Background technology]

[0002] In the outdoor industry, gas canisters that are carried along with cooking equipment are widely known, and in particular, gas canisters called OD canisters are most frequently used (see, for example, Patent Document 1).

[0003] Gas canisters with a dome-shaped top lid, such as OD cans, are widely used to heat cooking utensils in outdoor activities, but due to the nature of outdoor use, their surfaces may become scratched or dirty. In addition, the surface may be scratched not only during use but also during transportation and storage, and such damage is a concern in terms of aesthetics and safety. Therefore, it is desirable to use a dedicated cover to protect the surface of the gas canister. Here, covers attached to such gas canisters are well known in the outdoor industry (see, for example, Non-Patent Document 1, Non-Patent Document 2, and Non-Patent Document 3).

[0006] In conventional covers, a plurality of cover members each having a shape in which the entire surface of the dome-shaped upper lid to be protected is divided into several sections are often connected together by sewing them together or by fastening them together with fasteners. When the cover members are connected together with fasteners, the metal fittings themselves may scratch the painted surface of the gas canister, causing peeling of the paint or damage to the metal surface, and this is considered to be undesirable from the viewpoint of safety. On the other hand, although it is mainstream for the cover members to be connected together by sewing, sewing to connect the covers together requires a certain level of skill, so they must already be sewn when sold, and most are sold as finished products already connected together. Therefore, since they are delivered in a finished three-dimensional shape, they are bulky and inconvenient to carry, and since they are already finished products, it is difficult for users to customize and replace the material and color of the cover members.

[0007] The present invention aims to solve such conventional problems and to provide a cover that is easy to manufacture, has excellent functionality as a cover, is easy to carry, and can be easily customized by the user. [Means for solving the problem]

[0008] The cover according to the present invention is composed of a plurality of cover members, and the cover is integrally formed by connecting the plurality of cover members to each other, and each of the cover members has a shape in which the entire surface of the dome-shaped upper lid portion is divided into a plurality of sections, and the cover members are provided with connecting portions for connecting the cover members to each other, and the connecting portions are of a type that allows the cover members to be detachably connected by a form fitting and / or a friction fitting. Effect of the Invention

[0009] The cover of the present invention is a type in which each cover component is detachably connected by a form connection and / or a friction connection, and the cover components can be punched out at the same time using a die such as a punch, and since the entire top lid is properly covered without the need for metal fittings, it has excellent functionality as a cover.It does not need to be assembled at the time of sale, making it easy to ship and transport, and it is also possible for users to combine cover components of different materials and colors to suit their preferences. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 shows a top view and a perspective view of the entire connected cover, as well as a perspective view of an object such as an OD can having a domed top. [Diagram 2] FIG. 2 shows the individual structure of the cover members before connection, which form part of the entire cover. [Diagram 3] FIG. 3 shows an exemplary structure of the link. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The cover of the present invention is a cover that mainly covers the dome-shaped top lid portion of an object such as an OD can, which is composed of a bottom portion and a dome-shaped top lid portion connected to the bottom portion, and is characterized in that the cover is composed of a plurality of cover members, which are connected to each other to form a single unit, each of the cover members having a shape in which the entire surface of the dome-shaped top lid portion is divided into a plurality of sections, and which is provided with connecting portions for connecting the cover members to each other, and which are of a type that allows the cover members to be detachably connected by shape connection and / or friction connection.

[0012] Shape and size of cover material: The shape and size of the cover member are not particularly limited as long as they cover the entire surface of the dome-shaped upper lid when all the cover members are connected. For example, when the upper lid is hemispherical, a plurality of fan-shaped cover members can be combined to smoothly cover it. Preferably, the cover member can be formed into a fan shape that spreads radially from the center of the gas outlet. In this case, when the fan shape spreads radially from the center of the gas outlet in six equal parts, the central angle θ is 360 degrees / 6=approximately 60 degrees (see FIG. 1(a)). In the case of a fan shape that spreads radially, it is preferable that the shape spreads in six to eight equal parts from the gas outlet, that is, the central angle is preferably approximately 45 degrees to approximately 60 degrees. The central angle is an approximate value because the surface of an object such as a gas can may be slightly curved, and it is easy for a person skilled in the art to adjust the shape of the cover member to match the curvature. On the other hand, the cover member may be formed into a shape that covers not only the dome-shaped upper lid but also the bottom surface. It is preferable that the plurality of cover members are separate structures, but they may be connected as materials without being separated from each other.

[0013] Link structure: Each cover member is provided with a connecting portion that allows the cover members to be connected to each other, and the connecting portion has a structure that allows the cover members to be connected detachably by form connection and / or friction connection (see FIG. 3). For example, by forming a shape including projections and grooves that can fit together like a jigsaw puzzle at the edge of the cover member, each member can be connected without sewing or metal fittings (see FIGS. 3(a) and (b)). However, most preferably, as shown in FIG. 3(c), holes are provided alternately at the corresponding points to be connected of the cover members, arranged at intervals slightly shorter than the diameter of the holes, and a cut is made from the center of each hole toward the connecting direction, so that the cover members can be interlocked with each other. In this way, the connection is sufficiently strong not only due to the geometric intertwining of the connecting portions but also due to the friction between the materials, while the connection can be easily released and the user can easily attach and remove the cover members by themselves. Therefore, if a punch or other die for cutting out cover members of this shape is made, it is possible to quickly cut out a large number of cover members from the material sheet. It is also possible to produce cover members of the same shape in various colors, allowing users to complete the cover with their preferred color combination. In addition to color combinations, it is also possible to combine cover members made of various materials.

[0014] Material Selection: The cover member is not particularly limited as long as it is a material that has flexibility, impact resistance, and fire resistance when used with a gas canister, and for example, leather, silicone, or rubber can be used. From the viewpoint of protection and high coefficient of friction when connected, leather is the most preferable material. When leather is used, there is a limit to the size of the material because it is a natural material. In this invention, the size of the cover member can be appropriately determined, and by designing the size of one cover member to be small, small materials and scraps can be effectively used, so there is a possibility that materials that would otherwise be discarded can be effectively used.

[0015] How to wear: The user can easily cover the entire device by connecting each cover member together using the connecting mechanism and attaching the connected cover to the dome-shaped upper lid. In addition, the separate structure in which the parts are not connected makes it easy to carry, disassemble after use, and store. EXAMPLES

[0016] An embodiment will be described below with reference to the accompanying drawings. In (a) of FIG. 1, a cover 1 formed by connecting a plurality of cover members 2 to each other is shown. In (b) of FIG. 1, an exemplary gas can to be protected by the cover 1 is shown, which is composed of a top lid portion 3, a bottom portion 4, and a gas outlet 5. The cover 1 attached to the top lid portion 3 of the gas can is composed of cover members 2 each having a shape that divides the entire surface of the top lid portion 3 of the gas can into a plurality of sections. In (a) of FIG. 1, an example of a cover member 2 having a fan shape that spreads radially in six equal parts from the center of the gas outlet, i.e., the central angle θ is approximately 60 degrees. By connecting all the cover members 2 integrally, a cover 1 that covers the entire surface of the gas can is formed.

[0017] As shown in FIG. 2, the cover member 2 has a connecting portion 6 along its edge that can be connected to a corresponding cover member 2. The cover member shown in FIG. 2 has an upper portion in the shape of a fan that spreads radially from the center of the gas outlet 5, and a lower portion that extends almost vertically from the bottom end of the upper portion, which is due to the fact that the side of the dome-shaped top lid of the gas can has a substantially cylindrical shape. The shape of each cover member that covers such a dome-shaped top lid can be determined in consideration of the three-dimensional shape of the dome-shaped top lid. For example, the shape can be determined by accurately measuring the dome-shaped top lid, a three-dimensional drawing of the gas can is created on a computer and the shape of the cover member can be freely determined from the data, or the shape of the cover member can be determined by forming a film of rubber such as latex on the dome-shaped top lid and cutting the film into a desired shape. If the upper portion of the cover member 2 is formed into a fan shape that spreads radially from the center of the gas outlet 5 in six equal parts, the central angle θ is 360 degrees / 6 = approximately 60 degrees (see FIG. 1(a)). In this case, it is preferable that the shape expands in six to eight equal parts from gas exhaust port 5 as the center, that is, the central angle is preferably about 45 degrees to about 60 degrees.

[0018] FIG. 3 shows an exemplary shape of the connecting part. FIG. 3(a) and (b) show a form-fitting connecting part having a structure in which the concaves and convexities fit together like a jigsaw puzzle, and FIG. 3(c) shows an example of a connecting part before connection (c) and after connection (c') that fits together like a zipper. In FIG. 3(a) and (b), the corresponding concaves and convexities simply fit together in the gaps, whereas in FIG. 3(c), the corresponding convexities and convexities are fitted together and then intertwined, resulting in a form-fitting and friction-fitting connecting form. It is particularly preferable to adopt the connecting mechanism of FIG. 3(c) because once connected, the cover members 2 maintain a strong connection with each other. Furthermore, it is most preferable to adopt leather as the material.

[0019] According to the cover 1 of the present invention, the connection of the cover members 2 does not require sewing or metal fittings, and once the shape of the cover members 2 is decided, they can be cut out as a single unit using a die of that shape, and the manufacturer / seller can sell them in an unconnected state without performing the connection work. In addition, the cover members 2 of the present invention are of a type that are detachably connected by shape connection and / or friction connection, and the cover members 2 can be punched out with a die such as a punch together with the connecting parts. Furthermore, since the entire upper lid part is appropriately covered without metal fittings, it has excellent functionality as a cover 1, and since it does not need to be assembled at the time of sale, it is easy to deliver and carry, and since the connecting parts can be detached, it is possible to combine cover members 2 of different materials and colors according to the user's preference.

[0020] It goes without saying that the present invention is not limited to the above-described embodiment, and the shape and material can be selected arbitrarily. [Explanation of symbols]
