Japanese Patent Laid-Open No. 11-290731

  By the way, the shroud of the ejector described in Patent Document 1 is usually composed of a single part, and the appearance is not much different from other products. For this reason, as specific countermeasures for differentiating from other products, it is possible to add color to the surface of the shroud, attach a decorative seal, or change the shape and size of the shroud itself. However, such countermeasures require a separate color application process and sticker application process, and if there is a change in size or shape, the mold used must be changed. There is a possibility that the production efficiency may be lowered or the molding performance may be greatly impaired, and it has not been possible to improve the decorativeness and functionality accompanying the partial change in material.

  An object of the present invention is to solve such problems. The object of the present invention is to improve the decoration efficiency (color, etc.), texture, physical properties, etc. of the shroud that covers the main body, in particular, in terms of production efficiency. We are proposing a new trigger type liquid ejector that can be clearly differentiated from other products by changing without impairing the reduction and molding ability.

The present invention includes a main body provided with a pump that sucks, pressurizes, and pumps an internal solution in a container, an operation lever that is supported by the main body so as to be swingable, and that drives the pump by repeating checks. A nozzle that is provided in front of the main body and that ejects the pressurized inner solution toward the outside, a top wall, and side walls that are continuous on both sides of the top wall, leaving the operation lever and the nozzle. A trigger type liquid ejector comprising a shroud that covers the main body,
The shroud is a trigger type liquid ejector configured by an assembly of a plurality of members fitted to each other.

  By the way, the shroud is divided into an upper portion having a large portion of the top wall, a lower portion having a flat plate portion adjacent to the lower surface of the top wall, the upper and lower guide ribs extending in the horizontal direction as the remainder. The upper portion has a retaining foot protruding from the lower end of the side wall and a tenon projecting from the lower surface of the top wall, and the lower portion is fitted to the upper guide rib to allow the retaining foot to be inserted. It is preferable that the flat plate portion has a mortise hole that allows insertion of a mortise, and a retaining foot is formed to protrude at the lower ends of both side walls, and the retaining foot is provided on each side wall. It is preferable to form a pair of protrusions and to project a plurality of tenons on the upper part. Furthermore, it is preferable that the upper part and the lower part are made of different materials and / or colors.

Since the trigger type liquid ejector of the present invention is composed of an assembly of a plurality of members fitted together with each other, by changing the color, material, etc. of each part of the component, The distinguishability from other products can be improved.
In addition, when the shroud has a two-part configuration consisting of an upper part and a lower part, it can be decorated without changing the size or design of the shroud by changing the color, material, etc. of both parts as required. In addition to enhancing the properties, it is possible to easily realize changes in physical properties such as changes in texture and impact resistance, thereby enhancing discrimination from other products.
In addition, by fitting the retaining leg of the upper part into the fitting hole of the existing upper guide rib extending in the horizontal direction of the lower part, and by fitting the tenon of the upper part into the tenon hole of the flat part of the lower part, The upper part and the lower part can be firmly and securely fixed without significantly reducing the molding ability and the like.

  Here, in the case where the upper part retaining leg is formed to protrude on both side walls, the upper part and the lower part can be more firmly fixed. This means that the retaining leg is attached to each side wall. It is even more effective when a pair of protrusions are formed.

  This also applies to the case where a plurality of tenons fitted on the flat plate portion of the lower portion are provided in the upper portion.
