Description

  The present invention relates to a trigger type liquid ejection container.

The actuating member is erected upward from the inside of the cylinder mounted in the container body and the head with the nozzle is fitted to the upper end, and the arm from the mounting cylinder fitted to the outer surface of the container mouth neck is upward and outward. The trigger base portion and the trigger intermediate portion are pivotally attached to the arm tip portion and the upper portion of the head, and the liquid in the container is ejected from the nozzle through the working member by the pulling operation of the trigger tip portion. A trigger-type liquid ejection container provided in such a manner is known (Patent Document 1).
JP 2005-125189 A.

In the conventional container as described above, is it generally possible to fit the pin shaft protruding from the left and right side surfaces of the head and the arm tip into the bearing holes drilled in the left and right side walls of the trigger integrally formed of a synthetic resin material? In addition, they are fitted into bearing recesses provided on the inner surfaces of the left and right side walls.
When the pin shaft is fitted into the bearing hole, the outer end surface of the pin shaft is exposed to the outer surface of the trigger side wall. When the bearing concave portion is provided, a raised portion is provided on the inner surface of the trigger side wall. Since the bearing concave portion is formed in the center, so-called sink marks are likely to be generated around the outer surface of the side wall portion provided with the raised portion. Such sinks and pin shaft outer end surfaces have no functional problem at all, but the use of a trigger having such sinks or the like as a member of a container for ejection of expensive cosmetics or the like has an inferior appearance. Therefore, it is not preferable.

  The present invention is a liquid ejection container with a trigger that does not have the above-mentioned sinks and has an excellent appearance.

As a first means, the actuating member is erected upward from the inside of the cylinder of the container body, and the arm is erected upward and outward from the mounting cylinder fitted to the outer surface of the container body neck. The upper end of the nozzle and the upper part of the head with the nozzle at the upper end of the actuating member are pivotally attached to the left and right side walls of the trigger base and the middle of the trigger so that the liquid in the container can be ejected from the nozzle by pulling the trigger tip. In the trigger type liquid ejection container,
An interposition member 13 was provided on the inner surface of the trigger, and the left and right side portions of the tip of the arm 7 and the head 3 were pivoted to the left and right side plates of the trigger 11 indirectly via the interposition member.
As a second means, the first means and the interposition member 13 are suspended from the left and right sides of the top plate 14 with the left and right side plates 15 hanging down, and the lower surfaces are opened to the rear and front sides of the both side plates, and A shaft hole 16 having a diameter larger than the minimum width of the opening portion is formed, and shaft holes are formed on the second and first pin shafts 8 and 5 protruding from the left and right side surfaces of the arm tip and the head. By pressing the 16 openings, the pin shafts were formed so as to be able to be fitted into the shaft holes.
As a third means, the first or second means is provided, and the wall thickness of the left and right side wall portions of the trigger is made substantially uniform.

  By making it like Claim 1, since the recessed part as a sink mark is not formed in a trigger pivot attachment part outer surface, and a pin-shaft outer end surface is not exposed, the trigger outer surface can be made into the trigger which was smooth and excellent in the external appearance. I can do it.

  By making it like Claim 2, the assembly | attachment of a trigger can be made easy.

  By making it like Claim 3, the sink of an outer surface of a trigger is prevented more effectively.

  A first embodiment shown in FIGS. 1 to 4 will be described.

  First, a conventional well-known part will be briefly described. Reference numeral 1 denotes a container body that stands up the mouth and neck, a cylinder is suspended from the container body, and the nozzle 2 is urged upward from the inside of the cylinder. The operating member 4 to which the attached head 3 is fitted is raised. A mounting cylinder 6 is screwed onto the outer surface of the container mouth, neck, and the first pin shaft 5 protrudes from the left and right outer surfaces of the head to the left and right sides. The arm 7 is erected rearward. The arms stand on the left and right side walls from both the left and right sides of the bottom plate, the rear ends of these side walls are discs, and the second pin shaft 8 protrudes from the center of the disc to the left and right.

  Reference numeral 11 denotes a trigger for pivotally attaching the trigger base and the trigger intermediate portion to the upper end of the arm 7 and the head 3. A nozzle insertion hole 12 is formed in the trigger top plate portion in front of the intermediate pivot portion so that the nozzle tip protrudes forward and outward from the insertion hole.

  In the present invention, an interposition member 13 is provided on the inner surface of the trigger 11, and the pivot, the arm tip, and the head 3 are pivotally connected via the interposition member 13.

  In the illustrated example, the interposition member 13 hangs down the left and right side plates 15 from both sides of the top plate 14, and shaft holes 16 that open the lower surface are formed in the rear and front sides of the left and right side plates.

The opening on the bottom surface is formed by a C-shaped facing slope, and the upper end of both slopes is used as the entrance to the shaft hole, and the width of the entrance that has the smallest opening width in the opening is the shaft hole. It is formed narrower than the diameter.
With the above configuration, the left and right side plates 15 of the interposition member 13 can be formed with a substantially uniform wall thickness, and the occurrence of sink marks on the outer surface of the interposition member 13 is effectively prevented, and the trigger is particularly transparent. Or when it is made translucent, the appearance is excellent.

The pressing plate 11b is suspended from the lower surface of the trigger upper plate 11a, and the lower surface of the pressing plate is brought into contact with the top plate 14 of the interposing member 13. The left and right side plates 15 of the interposed member 13 may be fixed to the inner surfaces of the left and right side walls 11c of the trigger 11 by appropriate means.
For example, as long as the appearance of the outer surface of the trigger is not impaired, ridges and ridges are formed on the inner surfaces of the left and right side walls of the trigger, and corresponding ridges and ridges are formed on the outer surfaces of the left and right side plates 15 of the interposition member 13. Then, both may be fitted by unevenness.
Further, the pivoting of the interposition member 13 with the arm tip and the head 3 is not limited to the above form. For example, a pivot pin is provided on the interposition member 13 to form a bearing recess at the arm tip. May be.

  In the above embodiment, the left and right side walls of the trigger are formed with a substantially uniform wall thickness, but a trigger having an excellent appearance can be obtained by gradually changing the wall thickness.

  FIG. 5 shows a second embodiment. In this embodiment, the nozzle 2 is projected rearward through an insertion hole 12 drilled in the rear part of the trigger upper plate 11a, and the liquid ejection container is used when, for example, liquid is ejected to the head or the like.

  In the above configuration, when the container body 1 is held at the top and the tip of the trigger is pulled, the trigger 11 swings downward about the second pin shaft 8 protruding from the left and right cylinder side surfaces at the upper end of the arm, and thus the middle of the trigger The part pushes down the head 3 and ejects the liquid in the container from the nozzle 2.

It is the side view which notched a part of this invention container. 1 is a plan view of the container. It is a side view of a part notch shown in a trigger pulling operation state. It is sectional drawing of a main member. It is a side view of the partial notch shown in 2nd Embodiment.
