Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a valve protection cap for a high-pressure gas container having a ring-shaped part attached to a neck ring part on the gas container side and a protection cylinder part standing upright from the ring and surrounding the valve.

[0002]

[Prior art]

 As shown in FIGS. 6 and 7, this type of protective cap a has a ring-shaped portion c to be attached to the neck ring portion b and a protective tubular portion e surrounding the valve d. On the inner bottom portion of the cap a, concave grooves f are annularly provided, and ribs g are radially provided. For this reason, there is a drawback that liquid, dust, and the like collect in the concave groove f and easily get dirty. Further, since the opening h is formed in the cap a, it is necessary to put a hand on the frame part j above it when it is transported, and at that time, the corner m bites into the pad of the finger and causes pain. There was also.

[Problems to be solved by the device]

 The present invention has been made in view of the above points, and its problem is that it is less likely to be contaminated with water, dust, etc., and is suitable for high-pressure gas containers related to food and chemicals, and easy to handle. Is.

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention forms a corrugated portion 15 for positioning a finger on a frame portion 14 adjacent to an opening 13 for holding a hand during transportation, and A thick portion 16 is formed on the inner surface side, and an upper surface 17 extending from the ring-shaped portion 11 to the protective cylinder portion 12 is formed by a flat surface 18 or a sloped surface 19 which is inclined outward in order to improve drainage. .

BEST MODE FOR CARRYING OUT THE INVENTION A protective cap 10 of the present invention comprises a ring-shaped portion 11 for attaching to the neck ring portion b on the side of a gas container B, and a protective cylinder portion 12 which stands up from the ring-shaped portion 11 and surrounds a valve d. Have.

The protective cylinder portion 12 is intended for valve protection, but an opening portion 13 is provided on the side surface of the main body for convenience of approaching the valve and handling. In the present invention, the frame portion 14 adjacent above the opening portion 13 is positively used as a portion for holding a hand during transportation. Therefore, the frame portion 14 has a vertical width that can be easily grasped by a hand, and a corrugated portion 15 for positioning a hooked finger is formed on the lower side of the frame portion 14. This corrugated portion 15 is provided with several sets of recesses and protrusions alternately.

Further, a thick portion 16 is formed on the inner surface side of the corrugated portion 15. This increases the contact area of the finger to disperse the force, and the corners are rounded (Fig. 4 (b)), which significantly reduces the burden on the finger during transportation. Further, since the thick portion 16 is provided on the inner side, the outer shape of the cap does not increase even if the wall thickness is sufficiently thick. Further, since the thickness is lower in the lower part, when the cap 10 is manufactured by resin molding, it is easy and inexpensive to make a mold.

Further, in order to improve the drainage property, the upper surface from the upper surface of the ring-shaped portion 11 to the protective cylinder portion 12 is constituted by a flat surface 18 or an inclined surface 19 which is inclined outward. The flat surface 18 is a contact surface of the retaining ring p 1. The upper surface 17 corresponds to the bottom surface when viewed as an empty space inside the cap body, and is a place where liquid and dust easily collect. Therefore, the upper surface of the innermost ring-shaped portion 11 as a whole is formed with an inclined surface 19 having an inclination toward the outside, and the outermost portion is formed by a gentle inclined surface 19 'to provide a shape in which liquid and dust are hard to collect and easy to clean. (See FIGS. 5A and 5B). Reference numeral 19 "denotes a ridgeline formed by the gentle slope 19 '.

The illustrated cap 10 is provided with a closed opening 13 and an open opening 13 ′. The outer inclined slope 19 is a conical surface, and the gentle slope 19 'is a roof-shaped surface. The liquid that has fallen inward is directed to the outside. Of course, the sloped surface 19 may be formed by a simpler conical surface, curved surface, or the like. Such a protective cap 10 is formed of a light alloy or a synthetic resin material in addition to the conventionally used metal material.

[Effect of the invention]

The present invention is configured and operates as described above, and it is easy to handle even if it is hand-carried during transportation, and it is easy to handle. It is easy and suitable for foods and chemicals such as CO ₂ containers for draft beer and other beverages.
