  By the way, this type of conventional quantitative discharge container usually has a fixed amount that can be measured in one operation, and in many cases it is necessary to invert the container itself for measurement, and it is easy to use. It wasn't.

  An object of the present invention is to propose a novel quantitative discharge container capable of variable quantitative determination and capable of easily discharging contents by one-handed operation.

The present invention has a body having an opening at the upper end and a lower end, respectively, and a body forming an internal space for storing contents therein, and is detachably attached to the opening at the lower end of the body to discharge the contents in the body. A predetermined amount of contents in the fuselage having a bottom lid having at least one opening, an upper lid detachably attached to the mouth of the upper end of the fuselage, and a valve body that opens and closes a hole in the bottom wall A weighing chamber for receiving the sample, a slider that can be reciprocated in the weighing chamber and elastically supported in a direction away from the bottom wall of the weighing chamber, and connected to the back surface of the slider to pass through the opening of the upper lid. A push-in operation part that projects the end part to the outside,
The slider has a main body part for introducing the contents of the fuselage into the measuring chamber through an opening formed in the peripheral wall, and is held by the peripheral wall of the main body part so as to be slidable along the axial center thereof. A press disk that closes the opening and pressurizes the contents in the weighing chamber and discharges it from the opening of the bottom lid,
The pushing operation portions have different lengths toward the ends thereof, and are composed of a plurality of vertical ribs that are selectively locked to the inner edge of the opening of the upper lid to change the pushing amount of the slider. It is a variable dispensing container.

  In the variable-quantity discharge container configured as described above, the valve body is connected to the leg portion so as to be slidable through an opening in the bottom wall, and the measurement chamber is shifted to a negative pressure state by being connected to the leg portion. It is possible to apply a body part that slides with the leg part only to close the opening of the bottom wall only when the valve body is pressed toward the bottom wall of the measuring chamber to close the opening of the bottom wall. You may provide the spring hold | maintained in a state.

  The rod may be slidable along the inner wall of the fuselage and may be provided with a fin-shaped guide that guides linear movement when the slider is pushed. It is desirable to dispose a stand cover that stands and forms a gap between the bottom lid and the ground plane.

  Furthermore, a convex portion can be formed between the valve body and the bottom cover so as to secure a discharge path for the contents by forming a gap between them.

  The contents in the weighing chamber can be discharged by a simple operation of pushing the slider in the push-in operation unit without inverting the container. In addition, by appropriately selecting the vertical ribs of the push-in operation portion and engaging with the inner edge of the opening of the upper lid, the push-in amount of the slider can be changed, and variable quantitative discharge can be realized.

  When the contents are discharged and the contents are taken into the measuring chamber (when the slider returns to the initial position and the measuring chamber is in a negative pressure state), the opening of the bottom lid is closed by the valve body. Inflow of air from the hole can be prevented, and accurate quantitative discharge becomes possible.

Hereinafter, the present invention will be described more specifically with reference to the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of a variable quantitative discharge container according to the present invention.

  In the figure, reference numeral 1 denotes a body having an internal space for storing contents. The body 1 has mouth portions 1a and 1b connected to the internal space at the upper end and the lower end, respectively. Reference numeral 2 denotes a bottom lid that is detachably attached to the mouth 1a at the lower end of the body 1 by screw engagement (may be undercut). The bottom lid 2 discharges the contents in the body 1. A plurality of apertures 2a are provided. Here, although the case where a plurality of the apertures 2a are provided is illustrated, it is sufficient that at least one aperture 2a is formed, and the diameter thereof is appropriately set according to the viscosity of the contents. When the bottom lid 2 is attached to the mouth 1a of the body 1, it may be attached directly, or as shown in the figure, it may be attached via another member such as a measuring chamber described later.

  Reference numeral 3 denotes an upper lid that is detachably attached (screw or undercut, etc.) to the mouth 1b at the upper end of the body 1 and seals the mouth 1b. It is a weighing room. On the outer periphery of the measuring chamber 4, a screw cylinder 4a having a screw portion that is screw-engaged with the mouth portion 1a is integrally formed, and a screw cylinder 4b for mounting the bottom lid 2 is formed below the screw cylinder 4a. Has been. Further, reference numeral 5 denotes a valve body provided on the bottom wall 4c of the measuring chamber 4. The valve body 5 includes a leg portion 5a that is slidably locked in the opening h of the bottom wall 4c, and the leg portion 5a. Only when the inside of the measuring chamber 4 shifts to a negative pressure state, the main body portion 5b slides with the leg portion 5a to close the hole h of the bottom wall 4c.

A slider 6 is reciprocally movable in the measuring chamber 4 and elastically supported in a direction away from the bottom wall 4c of the measuring chamber 4. The slider 6 includes a cylindrical main body portion 6a having a mouth portion opened downward and a pressing disk 6b. An opening 6a ₁ for introducing the contents in the body 1 into the measuring chamber 4 and an annular stopper 6a ₂ extending along the circumference of the peripheral portion of the main body portion 6a of the slider 6 (protrusions provided intermittently) And a retaining disc undercut 6a ₃ is formed between the annular stopper 6a _{2 on} the peripheral wall of the main body portion 6a and the retaining undercut 6a _3. It is slidably held along the core O.

  7 is a pushing operation for reciprocating the slider 6 in the measuring chamber 4 by connecting one end to the back surface of the slider 6 and projecting the end through the opening 3a of the upper lid 3 and pushing the end. Part.

  The pushing operation portion 7 is composed of a plurality of vertical ribs 7a to 7d. Of the three ribs 7a to 7c, the outward projecting width is increased and the length toward the end is L. Are set to be different from each other, and the end portions 7a ′ to 7c ′ are selectively locked to the opening inner edge portion 3a ′ of the upper lid 3 to change the pushing amount of the slider 6. Although the push operation unit 7 is illustrated with four vertical ribs 7a to 7c, the push operation unit 7 is formed in a columnar shape without the vertical ribs 7a to 7c, and abutment for changing the push amount on the side surface. A plurality of (three in the above embodiment) vertical ribs forming the end may be extended. The vertical ribs that form the abutting end are not limited to those formed over the entire height of the push-in operation unit 7, but can be formed only above the fin-shaped guides described later. In addition, although the opening inner edge 3a ′ of the upper lid 3 is illustrated as a thin wall portion, it is naturally possible to configure it with the same thickness as the thickness of the upper lid 3.

  Further, 8 is disposed at the lower end of the body 1 (screwed or undercut engagement, etc.), and the body 1 itself stands up on the ground surface, and a stand cover that forms a gap δ between the bottom lid 2 and the ground surface ( In the illustrated example, it is formed so as to be continuous with the lower end of the screw cylinder 4 a), and 9 is a fin-shaped guide that is integrally formed with the push-in operation portion 7 and that can slide along the inner wall of the body 1. At least two guides 9 are formed (the number of guides may be two or more), and has a function of guiding the linear movement of the slider 6 when the slider 6 is pushed by the pushing operation unit 7.

In Figure 1, in a state opening 6a ₁ to open the main body portion 6a of the slider 6, the contents of the fuselage 1 is adapted to enter in the figure the metering chamber 4 as shown by the arrow through the opening 6a ₁ by its own weight ing. Note that the body portion 6a of the slider 6 has been illustrated as tubular, the invention is not limited thereto and may be formed an opening 6a ₁ by the groove body portion 6a as solid.

  Here, when a force is applied to the push-in operation unit 7 and pushed in, the main body portion 6a of the slider 6 is moved toward the bottom wall 4c by an equal distance in the measuring chamber 4.

Pressing the disk 6b by the movement of the body portion 6a of the slider 6 slides in the circumferential wall, but pressing pressure state disk 6b is opened 6a ₁ in contact with the annular stopper 6a ₂ is a closed (the body 1 and the metering chamber 4 and the pressing disks 6b (refer to the phantom line in FIG. 1), and the contents in the measuring chamber 4 are pressed by the pressing disk 6b and discharged through the opening 2a of the bottom lid 2 by the subsequent pressing.

  The contents in the measuring chamber 4 are discharged as much as the slider 6 is pushed in, and a certain amount of discharge can be performed here.

When the force applied to the pushing operation part 7 is released, the slider 6 returns to the initial position (position before pushing) together with the operation part 7 by the restoring force of the springs s that elastically supports it. opening 6a ₁ becomes open in the portion 6a, the contents of the fuselage 1 enters the metering chamber 4 through the opening 6a _1.

  At this time, the inside of the measuring chamber 4 has shifted to a negative pressure state, the main body portion 5b of the valve body 5 slides upward together with the leg portion 5a, the hole h of the bottom wall 4c is closed, and the bottom cover 2 Inflow of air from the opening 2a is avoided.

  The main body portion 5b of the valve body 5 naturally slides (lowers) together with the legs 5a and returns to the initial position when the contents are filled in the measuring chamber 4, but the valve body 5 and the bottom lid 2 A convex portion 10 is present between the two and the convex portion 10 (the convex portion 10 is formed integrally with either the valve body 5 or the bottom lid 2), thereby securing a discharge path 11 for the contents. Therefore, the contents are discharged smoothly. The convex part 10 can also be formed as a groove part. In this embodiment, since the opening 2a of the bottom cover 2 is always open, particularly in order to prevent the contents from flowing out due to their own weight, the area of the opening 2a of the bottom cover 2 and It is important to set the area of the opening 2a, the cross-sectional area of the discharge path, etc. so that there is no inadvertent outflow, taking into consideration the balance between the cross-sectional area of the discharge path and the viscosity of the contents. .

  FIG. 2 shows the end of the operation unit 7 and the upper lid 3. When a symbol as shown in the figure is provided on the upper lid 3 and any one of the longitudinal ribs 7a to 7c of the operating portion 7 is selected and its end portions 7a 'to 7c' are locked to the inner edge 3a 'of the opening, the slider 6 The amount of push-in is changed, which allows variable quantification. The symbol is formed by providing unevenness on the upper lid 3 or is provided by a method such as transfer / printing.

  FIG. 3 shows a main part of another embodiment of the discharge container according to the present invention. The discharge container is assembled with a valve body 13 having a spring 12 as shown in FIG. 4 (the spring 12 may be formed integrally with the valve body 13 or may be a separate body, made of resin or metal. The structure is such that the opening h of the bottom wall 4c of the measuring chamber 4 is normally closed and the contents are discharged only when the pressure reaches a predetermined pressure when the slider 6 is pushed in. It is.

This discharge container is advantageous for filling the contents having a relatively low viscosity, and the opening h is immediately closed as the pressure in the measuring chamber 4 drops, so that the opening 2a of the bottom lid 2 is opened. In addition to avoiding the inflow of air through the air, it is possible to cut the content when discharging the contents, thereby enabling more accurate quantitative discharge. In the example shown in the figure, the valve body 13 is opened to the opening 2a of the bottom cover 2 when the contents are discharged.
The resin spring 12 functions so as to secure a discharge path by forming a gap between the valve body 13 and the opening 2a when the slider 6 is fully pushed. Similar to the one shown in FIG. 1 above, it is also possible to secure a discharge path by providing a protrusion or a groove on at least one of the lower part of the valve body 13 and the inner surface of the bottom cover 2a.

  The stand cover 8 for erecting the body 1 has been shown as an example of a dome-shaped cross-sectional shape surrounding the bottom lid 2, but the shape of the stand cover 8 is not limited to the illustrated one, and the shape may be changed as appropriate. be able to.

  Whether to seal between the pressing disk 6b and the side wall of the measuring chamber 4 is arbitrarily selected. When the contents are food, etc., and the container is repeatedly washed and dried, it is preferable not to seal the part and to form a minute gap, in this case, the contents and the edge of the pressing disk 6b It is necessary to adjust the balance of the gap. When the contents are replenished, the upper lid 3 is removed.

  Variable quantification is feasible, and it is possible to provide a quantitative dispensing container with ease of use.
