Description

  The present invention relates to a pressing head alignment mechanism.

  As a pump-type dispenser, a fixed suction part mounted on a container body and an operation jet part mounted so as to be able to be pushed down in an upward biased state with respect to the fixed suction part are provided. Is known to be sucked into the fixed suction portion and ejected from the ejection port of the pressing head constituting the upper end of the working ejection portion.

  Further, as these dispensers, for the purpose of efficiently ejecting the stored liquid to the end, the lower end opening of the suction pipe constituting the lower end of the fixed suction part is bent at the front corner of the bottom of the container body, A configuration in which the pressing head is moved up and down by matching the opening direction of the jet port with the opening direction of the lower end of the pipe has been proposed. (For example, see Patent Document 1)

In the dispenser, the opening of the base cap and the cross-sectional shape of the pressing head have a substantially elliptical shape, and the outlet of the pressing head is provided toward the major or minor diameter direction of the approximate edge diameter. On the side where the spout is located, the distance from the axial center is shorter in the major axis or minor axis direction than the substantially elliptical cross section on the side opposite to the side where the spout is located. A step portion provided with a linear portion extending in a direction substantially orthogonal to the force for rotating in the direction is provided. More specifically, the stepped portion has a vertically long rectangular protrusion with a large and large protruding width at the front surface of the pressing head, and the protruding portion on the top wall of the base cap corresponding to the opening. Is provided with a fitting recess for fitting up and down. In addition, a longitudinally long rectangular recess having a wide recess and a large recess is provided in front of the pressing head circumferential surface, and a guide protrusion is provided on the top wall of the base cap at the position corresponding to the opening of the base cap so that the recess can be moved up and down.

  The conventional positioning mechanism described above can easily turn the spout toward the opening position of the lower end of the pipe, and there is little positional displacement of the spout with respect to the base cap, thus efficiently ejecting the stored liquid. In order to maintain the sufficient strength of the mechanism, the protrusion width or the recess width of the protrusion or recess becomes large, and the appearance may be impaired due to the presence of the remarkably conspicuous presence. On the other hand, when the protrusion width or the dent width is made small in order to eliminate these inconveniences, there is an inconvenience that the engagement is easily disengaged. Since this type of dispenser conventionally rotates the pressing head, if the user accidentally rotates the pressing head accidentally, this type of dispenser is generally made of synthetic resin, so that the protrusion from the recess is removed. There is a risk of removing it. In addition, since the outer periphery of the pressing head is limited to a specific form having an elliptical shape, there is an inconvenience that only a limited form is employed with no degree of freedom in the shape of the pressing head or the like.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 to FIG. 3 show an example of a pump-type dispenser 1 having a pressing head alignment mechanism according to the present invention. The dispenser 1 is a mist-like or foam-like liquid in the container body 100 depending on the selection of the internal structure or the like. And a fixed suction portion A and an operation ejection portion B are provided.

The fixed suction part A has an upper end fixed to the container body 100 and a lower part suspended from the container body 100. In the illustrated example, the upper part of the cylinder A ₂ with the lower part suspended in the container body 100 is fixed by the mounting cylinder member A ₁ fitted to the mouth / neck part 101 of the container body 100. The mounting cylinder member A ₁ has a flange-shaped peripheral wall 11 extending from the upper end of the peripheral wall 10 screwed to the outer periphery of the container body neck portion 101. Further, an inner guide cylinder 14a constituting the guide cylinder 14 is erected from the peripheral edge of the window hole from which the working jet B at the upper central portion of the peripheral wall 11 protrudes, and an outer guide cylinder 14b constituting the guide cylinder 14 is formed from the peripheral edge of the peripheral wall 11 Is standing. Further, a suction pipe 15 is fitted to the lower end of the cylinder A ₂ , and the pipe 15 is bent and opened at the bottom corner of the container body 100.

Actuating the ejection unit B is fitted a pressing head B ₂ to the upper end of the stem B ₁ which projects to be pushed above biasing condition from the window hole of the central wall 11 of the mounting tubular member A _1. In the pressing head B ₂ , a vertical cylinder 20 fitted to the outer peripheral upper end of the stem B ₁ is suspended from the back surface of the top plate 21, and a peripheral wall portion 22 is suspended from the peripheral portion of the top plate 21. In addition, a horizontal cylinder 23 is connected to the upper end portion of the vertical cylinder 20 and the other end passes through the peripheral wall portion 22 and is opened to the outside, and an outlet 24 is opened at the distal end of the horizontal cylinder 23. Yes. The lower end portion of the peripheral wall portion 22 is suspended so as to be pressed down between the inner guide tube 14a and the outer guide tube 14b. Further, an annular piston (not shown) that is slidably fitted into the cylinder A ₂ is provided as a working jet B at the lower part of the stem B ₁ that is suspended in the cylinder A ₂ . Furthermore, the upper biasing the actuating ejection part B are carried out by a coil spring is interposed in the cylinder A ₂ (not shown). Further, the suction valve at the lower end the cylinder A ₂ (not shown), in the stem B ₁ provided discharge valve (not shown), and these by and revealing the pumping mechanism. Then, sucks the container body of the liquid in the cylinder A ₂ by vertical movement of the actuating ejection part B, and then as configured ejected from ejection port 24 the liquid in the cylinder A _2.

  The positioning mechanism of the pressing head according to the present invention is provided in the dispenser 1 as described above, and this positioning mechanism is composed of a guide groove 16 and a protrusion 25. The guide groove 16 in this example is vertically provided on the front and rear outer surfaces of the inner guide cylinder 14a, and has a dovetail shape as shown in FIG. 2 or FIG.

  Further, the protrusion 25 has a similar cross-sectional shape slightly smaller than the cross-sectional shape of the guide groove 16, and is vertically provided on the inner surface of the pressing head peripheral wall portion 22 at the opposite position.

The guide grooves 16 must be formed in the elongated combined with at least a depressed width pressing head B _2, whereas, protrusion 25 may be shorter than the required length of the guide groove 16, but vertically formed as in the present example engagement strength therebetween by the rise can be more reliably prevented from coming off in the rotation of the excessive depressing head B _2. Such a configuration of the vertically long protrusion 25 can naturally be adopted in other examples.

The pressing head alignment mechanism configured as described above is installed so that the opening direction of the jet port 24 is directed toward the lower end opening direction of the pipe 15. For example, the position of the guide groove 16 and the protrusion 25 is set to a position where the opening direction of the jet outlet 24 and the lower end opening direction of the pipe 15 coincide with each other in a state where the guide groove 16 and the protrusion 25 are fitted. Accordingly, the alignment guide groove 16 does not necessarily have to protrude below the ejection port 24, and the position of the projection 25 is naturally changed accordingly. Although not limited to the case the guide groove 16 and the projection 25 provided always set, with facing spout 24 is reliably predetermined direction without selectivity in the fitting position of the pressing head B ₂ by providing a pair set is also very easy, for example, pressed head resetting when B ₂ is out even user easily performed, is not caused problems such as incorrect setting direction. The lower end opening of the pipe 15 is opened at the bottom corner of the container body.

  In this example, the guide groove 16 is provided on the inner guide cylinder 14a and the protrusion 25 is provided on the pressing head peripheral wall 22. However, the reverse may be possible, and the outer guide cylinder 14b and the pressing head may be reversed. The guide groove 16 may be provided on one of the peripheral wall portion 22 and the protrusion 25 may be provided on the other.

The case where the dispenser 1 configured as described above is used will be described. When ejecting the liquid, the liquid from the spout 24 by pushing down the pressing head B ₂ is ejected. Even when the amount of stored liquid is reduced, the lower end of the pipe 15 is opened at the front corner of the bottom portion, and the liquid can be ejected without remaining because the spout 24 faces forward.

4 through 6 show another example, shows an example of one position erected from the guide cylinder 14 the top rim portion of the mounting tubular member A _1. In this case, a pair of guide grooves 16 are provided vertically on the front and rear surfaces of the guide cylinder 14, and a pair of protrusions 25 are provided on the lower ends of the front and rear outer surface of the pressing head peripheral wall portion 22. The protrusion 25 in this case may be provided with the upper surface protruding upward from the guide tube 14, but it can be seen as an inconvenient protrusion by making the upper surface equal to or lower than the upper end of the guide tube 14. It is preferable because there is no. Since other configurations are basically the same as those in the example of FIG. 1, the same reference numerals are given and description thereof is omitted.

  Also in this case, the guide groove 16 may be provided on the pressing head peripheral wall portion 22, and the protrusion 25 may be provided on the guide tube 14.
