Description

[Detailed explanation of the idea] This proposal concerns a metered volume stopper made of synthetic resin.

BACKGROUND ART Conventionally, there is a stationary frame made of synthetic resin that has a discharge port opened in a part of the top wall of the plug and a metering chamber formed of a crank-shaped passage leading to the discharge port inside the top wall of the plug.

This type of device is used by fitting it into the mouth of a container containing an object to be measured, such as powder or granules, and then inverting the container to allow the object to be measured to flow into the weighing chamber. First, the container is held upright and the powder to be weighed that has flowed into the measuring chamber is temporarily stopped here to be weighed and separated, and then the container is turned upside down again and the powder to be weighed in the measuring chamber is weighed and discharged from the discharge port. be.

However, since the conventional device has a crank-shaped measuring chamber, it is necessary to fit at least two members to form the measuring chamber.

Therefore, a plurality of expensive molding molds are required, and molding and assembling takes time and expense, resulting in an extremely high cost.

The present invention attempts to eliminate such conventional drawbacks.

The illustrated embodiment will be described below.

As shown in FIGS. 1 to 3, the illustrated embodiment is made of a suitably synthetic resin, and has a fitting peripheral wall 2 hanging from the lower surface of the top wall 1 of the stopper into the container mouth. A pair of hanging walls 3, 3 of an appropriate width that protrude inward from one side of the inner surface of the peripheral wall 2 are vertically disposed facing each other at an appropriate interval, and a bottom wall 4 is provided between the lower ends of the hanging walls 3, 3, and A rising wall 5 of an appropriate height from the end of the bottom wall 4 is provided between the open side ends of the hanging walls 3, 3, and the hanging wall 3.3
A discharge port 6 is opened in the top wall 1 above the end on the side of the peripheral wall 2 between them, and a falling wall 7 of an appropriate height is hung between the hanging walls 3 and 3 from the mouth of the discharge port 6 on the side opposite to the peripheral wall. A measuring chamber 8 consisting of a crank-shaped passage is formed inside.

In addition, as shown in FIGS. 4 and 5, a part 4a of the bottom wall 4 forming the measuring chamber 8, the rising wall 5, and the measuring chamber 8 are shown in FIG.
The part 1a of the top wall 1 and the above-mentioned falling wall 7 are formed into a continuous cut-and-raised shape with thinned hinges 4b and 1b, respectively, and concave portions are formed on both sides of the cut-and-raised portions A and B. Grooves 4c, 4Ct lc, lc are formed, and protrusions 4d engage with these grooves at predetermined positions on the inner surfaces of the hanging walls 3, 3.

4d, ld, and ld are formed, and all are obtained by integral bottom shape, and the bottom shape is made by cutting and raising the parts A,
In B, the hinges 4b and lb are used to fold down, the grooves and the protrusions are engaged with each other, and the device is held in the predetermined position shown in FIGS. 1 to 3.

Note that this engagement and holding structure is not limited to this and may be any suitable structure.

It is also advisable to attach a sticker 9 to the discharge port 6 before use.

According to this proposal, it can be used in exactly the same way as before, and the part that forms the measuring chamber is formed into a continuous cut-and-raised shape with a hinge made thin in advance, which is then folded down and locked and held in a predetermined position. Since it consists of a measuring chamber, the whole can be obtained as a single unit by integral molding, the need for expensive molding molds can be minimized, and there is no trouble in assembly, reducing labor and costs, and improving yield. can be improved and provided at an extremely low cost.

Claims (1)

[Scope of utility model registration request] A discharge port is opened in a part of the top wall of the stopper, and a measuring chamber consisting of a crank-shaped passage leading to the discharge port is provided inside the top wall of the stopper, so that objects to be weighed such as powders and granules in the container can be removed. In a metering stopper made of resin, the flow is caused to flow from the inside of the container into the above-mentioned measuring chamber by raising and lowering the container, once stopped there for measurement, and then discharged from the outlet. A measuring chamber is formed by forming one or both of the bottom wall and the bottom wall into a continuous cut-and-raised shape with a thin hinge, which is then folded down and held in place. A quantitative stopper made of synthetic resin.
