Description

  The present invention relates to a trigger type liquid ejector, and in particular, it is possible to clean the surface to be ejected prior to the ejection of contents, or to quickly perform operations such as spreading the ejected material uniformly. It is intended to add functions that can be implemented.

  In containers containing liquids such as wrinkle removers, detergents, clothing paste, residential wax, hairdressing agents, fragrances, etc., the pump in the body is driven by checking the operating lever, and the liquid in the container In many cases, a trigger-type ejector is used that sprays the ink in a linear, mist-like or foam-like manner, thereby enabling efficient liquid supply.

  The purpose of this type of ejector is to inject the contents in the container in various forms as described above. In recent years, the surface to be ejected can be cleaned cleanly before the contents are ejected. In addition, high-functional products equipped with a wiping tool such as a brush have been developed so that the sprayed material can be uniformly spread after the contents are jetted (see, for example, Patent Document 1).

  Further, on the back side of the body 10, there is provided an engaging portion 10a (in the illustrated example, an upward claw shape) that is linked with a retaining cover piece of a head cover described later. Furthermore, a concave portion 10b that engages with a convex portion of a head cover described later is formed on the upper surface side of the body 10.

  Reference numeral 70 denotes a head cover attached to the outer surface of the body 10. The head cover 70 has a U-shape in which the upper surface side partition wall 71, the side surface side partition wall 72, and the rear surface side partition wall 73 are integrally connected so as to cover each of the upper surface, the side surface, and the back surface of the body 10, and the transverse cross-sectional shape is open. It will be.

  Further, as shown in FIG. 2, a groove 72 a extending in the lateral direction is provided on the inner surface of the side-surface partition wall 72, and the groove 72 a is guided to a convex rib (not shown) provided on the side surface of the body 10. By doing so, the head cover 70 can be attached to the body 10 by sliding from the back side. Note that the ribs may be provided on the side-surface side partition wall 72 by replacing the grooves 72a and the ribs with each other. Further, a convex portion 71 a that engages with the concave portion 10 b of the body 10 when the sliding of the head cover 70 is completed is provided on the lower surface of the upper surface side partition wall 71. A convex portion may be provided instead of the concave portion 10 b provided on the body 10, and a concave portion may be provided instead of the convex portion 71 a provided on the head cover 70.

  The back partition 73 is provided with a wiping portion 74 that can perform cleaning on the surface from which the contents are ejected. The wiping portion 74 in the illustrated example is a brush that is integrally formed of the same resin material as that of the back-side partition wall 73, but other than that, a plurality of hair bundles may be integrally connected by insert molding or the like. A felt or the like may be integrally connected, or these may be attached with an adhesive or the like.

A downward claw portion 75 a linked to the engaging portion 10 a of the body 10 is formed on the front side edge of the locking piece 75. In addition, the intermediate portion of the locking piece 75 has a shape protruding downward from the locking piece 75, and a pressing portion 75b serving as a portion to which a finger is applied when releasing the linkage between the engaging portion 10a and the claw portion 75a. Is provided.

  Further, the upper portion of the back-side partition wall 73 is provided with a stepped portion 76 in which the head cover 70 is recessed inward. As a result, as a result of the upper surface of the stepped portion 76 approaching the locking piece 75, when removing the head cover 70, the locking piece 75 can be pushed up with the thumb while the upper surface of the stepped portion 76 is pressed with a finger (for example, an index finger). It can be easily removed with one hand. Further, when the projection 77 is provided on the upper surface of the stepped portion 76, the projection 77 becomes a finger hook and the finger becomes difficult to slip, so that the head cover 70 can be removed more easily.

  The trigger type liquid ejector configured as described above repeatedly checks the operation lever 50 to drive the pump 11 in the body 10, whereby the contents in the container are introduced into the body 10 through the suction pipe 30. Then, it is injected from the injection nozzle 40 to the outside world. The internal structure of the trigger type liquid ejector according to the present invention is not limited to the illustrated example, and other structures that are usually used can be used.

  When the surface to be sprayed is cleaned in advance or when the contents after spraying are evenly spread, the head cover can be applied even if the wiping portion 74 is pressed against the work surface while the head cover 70 is attached. Since 70 is held so as to cover the upper surface and the side surface of the body 10, the applied force can be applied to the work surface as it is, so that the work can be performed efficiently.

  When the head cover 70 is removed, the claw 75a can be lifted and the head cover 70 can be removed simply by sliding the head cover 70 back, and the head cover 70 itself can be gripped. Compared to wiping tools, it is easier to hold and easier to apply force to the work surface. The used head cover 70 can be easily attached because the claw portion 75a and the convex portion 71a are engaged with the body 10 only by sliding from the back side.

  In the present embodiment, the head cover 70 is directly attached to the body 10. However, in the case of the ejector in which the body 10 is previously provided with a protective cover, the head cover 70 is attached from above the protective cover. May be.

  As shown in FIGS. 4 to 6, the head cover 70 may be provided with a connecting portion 72 b that connects the side surface partition walls 72 on the back side of the body 10. As a result, the head cover 70 is reinforced by the connecting portion 72b, so that it is difficult to be deformed when the head cover 70 is detached and used, and the application of force to the work surface can be performed more effectively.

  According to the present invention, since the head cover can be removed and used as a wiping tool, the grippable area becomes wider and easier to hold, and this makes it easier to apply force to the work surface, so that work can be performed efficiently. Furthermore, since the operation can be performed even while the ejector is mounted, it is possible to provide an easy-to-use trigger-type liquid ejector that can select attachment or detachment of the head cover according to the work situation.
