Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a feeding container that pushes up the contents stored in the container body and discharges the contents onto the surface of the coating head so that the contents can be applied, and the residual pressure generated when the contents are pushed out. It is intended to surely prevent unnecessary discharge caused by the above.
[0002]
[Prior art]
A feeding container that can discharge a suitable amount of solid or cream-like contents with relatively high viscosity to the application head and apply it directly, pushes out the contents stored and held in the container body from the opening part of the application head. The feeding mechanism is built into the bottom of the machine.
[0003]
The feeding mechanism is configured to slide the middle plate toward the coating head together with the screw rod by engaging the screw rod and the screw rod integrally connected to the middle plate, and rotating the middle plate to hold the contents. It is comprised by the rotating member to be made, and discharge amount can be adjusted with the rotation degree of a rotating member.
[0004]
By the way, the conventional feeding container is in a state where the rotation of the rotating member is stopped because the pressing force at that time remains in the contents in the container when the contents are discharged by sliding the inner tray. Regardless, there is a problem in that the contents are discharged from the opening of the coating head and the contents cannot be discharged efficiently.
[0005]
An object of the present invention is to propose a novel structure capable of preventing unnecessary discharge of contents due to residual pressure, which has been a problem in the conventional delivery container.
[0006]
[Means for Solving the Problems]
The present invention relates to a container main body for storing contents, an application head having a plurality of openings attached to the outer surface of the container main body and connected to the inside of the container main body, and contents stored in the container main body. A container that pushes up an object and discharges it through the opening of the coating head,
An inner plate that holds the contents and is slidable along the inner wall of the container body, a screw rod that is connected to the back surface of the inner plate, a base that movably supports the screw rod, a bottom wall of the container body, and A rotating body that is elastically supported between the bases and slides the intermediate dish together with the screw rod toward the coating head by rotation thereof;
The feeding container is characterized in that the rotating body is provided with vibration means for guiding the back suction of the contents by slightly moving the screw rod up and down together with the inner plate during the rotation.
[0007]
In the feeding container having the above-described configuration, the vibration means includes a convex portion provided on the base and a concave portion provided on the bottom surface of the rotating body that contacts the base, and is provided on the rotating body. And a convex portion provided on the bottom wall of the container main body that comes into contact with the rotating body, and a concave portion that conforms to the convex portion.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described more specifically with reference to the drawings.
1 (a) and 1 (b) are diagrams schematically showing the configuration of a feeding container according to the present invention.
[0009]
In FIG. 1, reference numeral 1 denotes a container body that stores the contents P. The container body 1 can be configured by combining an inner container 1a and an outer container 1b.
[0010]
Reference numeral 2 denotes an application head mounted on the mouth of the container body 1, and a plurality of apertures 2 a communicating with the inside of the container body 1 are provided on the outer surface thereof.
[0011]
3 is an overcap attached to the container main body 1 so as to cover the coating head 2, and 4 is a feeding means for pushing up the contents stored in the container main body to the outer surface through the openings 2 a of the coating head 2.
[0012]
The feeding means 4 holds the contents and is slidable along the inner wall of the inner container 1a, a screw rod 4b connected at the back (lower end) of the inner plate 4a, and moves the screw rod 4b. A base 4c that can be supported, and a rotating body 4d that is elastically supported between the bottom wall of the inner container 1a and the base 4c and slides the inner plate 4a together with the screw rod 4b toward the coating head 2 by rotation thereof. Yes.
[0013]
In addition, 5 is a cut-and-raised plate-like leaf spring for elastically supporting the rotating body 4d between the inner container 1a and the base 4c, and 6 is a very small screw rod 4b with the inner plate 4a while the rotating body 4d is rotating. It is a vibration means which guides the back suction of the contents P by moving up and down. The vibration means 6 has a saw blade-like convex portion 6a provided at an interval in the annular body of the base 4c and a bottom surface of the rotating body 4d that contacts the base 4c, and has a shape that fits the convex portion 6a. The ratchet is composed of a recess 6b as shown in FIG. 4, thereby constituting a ratchet that allows rotation in only one direction of the rotating body 4d, and performing quantitative discharge while moving the screw rod 4b up and down very slightly together with the inner plate 4a. .
[0014]
When the overcap 3 is removed and the rotating body 4d is rotated in order to discharge the contents P, the screw rod 4b that is screw-engaged with the rotating body 4d moves along the guide g of the base 4c to the coating head 2 along with the intermediate plate 4a. The content P held by the inner tray 4a is pushed up and discharged from the opening 2a of the coating head 2.
[0015]
At this time, since the concave portion 6b provided in the rotating body 4d moves over the convex portions 6a provided in the annular body of the base 4c one after another, the rotating body 4d, the screw rod 4b, the inner plate 4a, the contents P Moves up and down (vibrates) in a direction along the axis L of the screw rod 4b.
[0016]
When the rotating body 4d is stopped to stop the discharge of the contents P, so-called back suction is induced in which the inner plate 4a is drawn into the container body 1 by the amount that the rotating body 4d descends toward the bottom of the container body 1, Therefore, the pressing force applied to the discharge of the contents P is immediately released, and the contents are not discharged more than necessary due to the residual pressure.
[0017]
Although the rotating body 4d is illustrated as a ratchet type that allows rotation in only one direction, the convex portion 6a and the concave portion 6b may be provided with a gentle inclination and rotated in the reverse direction. The contents P can be drawn into the container.
[0018]
2 (a) to 2 (d) show other configurations of the feeding container according to the present invention.
[0019]
In this example, as shown in FIGS. 3 (a) and 3 (b), the protrusion 6a of the vibration means 6 is provided downward on the tip of the rotating body 6d, and the recess 6b conforming to the protrusion 6a. Is provided on the bottom wall of the inner container 1a so that the back suction similar to that of the structure shown in FIG. 1 can be induced.
[0020]
The leaf spring 5 that elastically supports the rotating body 4d between the container body 1 and the base 4c is shown in FIG. 1 as a leaf spring in which the bottom wall of the inner container 1a is cut and raised in a tongue shape. As shown in FIG. 3 (b), a member obtained by cutting and raising the tip wall of the rotating body 4d into a tongue shape may be applied.
[0021]
Further, the convex portion 6a and the concave portion 6b may be provided at a location as shown in FIG. 4 or FIG. 5, and the convex portion 6a and the concave portion 6b are installed according to the shapes of the base 4c and the rotating body 4d. It can be changed as appropriate.
[0022]
【The invention's effect】
According to the present invention, since no residual pressure is generated in the container when the contents are discharged, the contents are not discharged more than necessary, and the contents can be used efficiently.
