Abstract

(57) [Summary] [Purpose] To obtain a wide-mouthed cap for a cylinder that can provide identification that cannot be easily erased. [Structure] A projecting portion 10 is formed on a part of a peripheral wall of a main body 1 of a wide cap 20 so as to project to the outside.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wide mouth cap for a cylinder.

[0002]

[Prior art]

 Conventionally, in order to conveniently store and handle a gas fuel such as propane, it is generally liquefied and the liquefied gas is stored in a small pressure vessel, a so-called cylinder. There is. Further, in this type of cylinder, valves having an appropriate structure are attached to the end plate portion of the cylinder in order to inject and take out liquefied gas and the like into and from the cylinder. Further, in this type of cylinder, in order to protect the valves attached to the end plate portion thereof from the impact that may be received from the outside, the end plate portion of the cylinder is almost surrounded by the valve members. It is also common practice to attach a hollow cylindrical metal wide cap and surround the valves with the peripheral wall of the wide cap.

In addition, the peripheral wall of the wide cap has an opening for operating the valves enclosed by it from the outside, and various flexible containers connected to the valves. An opening for removing the tubing is also open.

Further, a label for indicating the type of liquefied gas stored inside the cylinder is usually attached to the outer surface of this type of wide mouth cap.

[0005]

[Problems to be solved by the device]

 However, the labels attached to the outer surface of the wide mouth cap are easily peeled off by contact with external articles during storage and handling of the cylinder, and therefore, the label is once peeled off. It is easy to cause inconvenience such as the type of liquefied gas stored in the cylinder becoming unknown, and it is possible to avoid an unexpected and dangerous accident due to the wrong type of gas. There is also concern that it will disappear. Then, this invention makes it a subject to be solved to obtain the novel wide-mouthed cap for cylinders which can prevent such fears effectively from occurring.

[0006]

[Means for Solving the Problems]

 According to the present invention, according to the present invention, a projecting portion having an appropriate peripheral contour is formed on a part of a portion of the peripheral wall of the wide-mouth cap excluding the various openings opened to the outside from the peripheral wall. This is solved by projecting it in the direction of.

[0007]

[Action]

 According to the present invention, since the projecting portion is formed so as to project outward on a part of the peripheral wall of the wide mouth cap, the type of liquefied gas or the like stored inside the cylinder is projected. Imprinting on the outer surface of the part makes it possible to give a semi-permanent identification that does not disappear during storage or use of the cylinder. If necessary, instead of directly marking the type of gas, etc., mark the bar code appropriately or apply a paint that does not easily come off and place it on the board. It is also possible to achieve the purpose of.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an embodiment thereof. First, FIGS. 1, 2 and 3 show one embodiment of the present invention by a front view, a bottom view and a vertical sectional view, respectively. The wide cap 20 according to this embodiment is a thin steel plate. Is formed into a main body 1 having a substantially cup-shaped vertical cross section, and the peripheral portion of the upper end portion is rounded outward to form a lip portion 2. Also, on the peripheral wall of the main body 1, a large opening portion 3 having a trapezoidal developed surface has a long side parallel to the rim portion 2 and is opened almost near the upper and lower end portions of the peripheral wall. In addition, a small quadrangular opening 4 is opened near the lower end in a diametrically opposed manner. The large and small openings 3 and 4 formed in the peripheral wall of the main body 1 are divided into two equal parts by one diameter surface including the central axis XX of the main body 1. The peripheral wall is divided by the diametrical surface at the lower part of the small opening 4 through the small slit 5.

Further, on the outer surface of the peripheral wall, one hexagonal nut-shaped stopper plate 6 is fixed to face each of the slits 5, and these stopper plates 6 penetrate them. It is adapted to be fastened to each other by the bolts 7 that operate. In this way, the main body 1 is inserted from its small-diameter lower end portion into the neck portion (not shown) fixed upright to the end plate portion of the cylinder, and the clasp 6 is tightened by the bolt 7 It is designed to be fixed to a cylinder. A narrow strip-shaped plate 8 is fixed to the outer peripheral surface of the lower end of the main body 1 in the shape of a truncated cone at its small diameter portion. When the main body 1 is attached to a cylinder, the strip 8 The lower surface of the cylinder contacts the outer peripheral surface of the end plate portion of the cylinder so that the main body 1 can be stably attached to the cylinder. Further, the upper side of the large opening 3 formed in the peripheral wall of the main body 1 is reinforced by a reinforcing plate 9 formed of a thin steel plate folded in two.

The wide mouth cap 20 having the above-described structure is substantially the same as the conventional one, and the wide mouth cap 20 has a main body 1 from an open end portion of the strip 8 fixed to a lower end portion thereof. , Insert the valves attached to the end plate of the cylinder so as to surround it, and with the inner peripheral surface of the strip 8 contacting the outer peripheral surface of the end plate portion of the cylinder, place the lower end of the main body 1 in By tightening the bolt 7 on the formed neck portion, it can be strongly attached.

Further, the large opening portion 3 formed on the peripheral wall of the main body 1 is useful for facilitating the operation of the valves attached to the cylinder from the outside, and the small opening portion 4 is provided. Is useful for connecting various flexible pipes to valves.

In the present invention, in the conventional wide mouth kypop 20 having such a structure, the width is provided in a part of the peripheral wall of the main body 1, for example, in the upper part of the small opening 4. It is characterized in that a projecting portion 10 having a substantially circular plane contour is formed so as to project from the peripheral wall on a diametrical surface that is divided into two equal parts. The projecting portion 10 allows the necessary engraving, bar code, or paint to be applied on the projecting outer surface.

As described above, according to the present invention, since the projecting portion 10 is provided on the peripheral wall of the main body 1 of the wide mouth cap 20, the projecting portion 10 can be used for various identification markings. Is. That is, the wide cap 20 according to the present invention is mounted on the end plate portion of the cylinder B with the inner surface of the band 8 downward so as to surround the valves attached thereto, as shown in the schematic view of FIG. It is installed by tightening bolts 7 at the neck portion formed upright on the end plate portion. In this case, it is stored on the outer surface of the top surface of the projecting portion 10, for example, in the cylinder B. The bar code R that indicates the type of liquefied gas that is used is engraved and used. In this embodiment, the protrusion 10 is formed from the peripheral wall of the wide cap 20 in order to mark the identification. However, if necessary, a recess may be used instead of the protrusion. Further, the installation position may be any position on the peripheral wall of the wide mouth cap.
