Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a device for cutting a notch to serve as a mouthpiece in a nipple for a baby bottle.

(Prior Art) Reference numeral 1 shown in FIGS. 4 and 5 is a conventionally well-known nipple for a baby bottle, and a milk suction port 1a is attached to the tip of a nipple body 1' made of soft synthetic rubber such as silicone.
At the same time, a cross-shaped notch 1a' is cut out, and a thin film-like and dome-shaped air intake valve body 1c' is formed in the flange 1b at the rear end periphery of the main body 1' to bulge out toward the inner surface. A notch 1d is made in the center of the tip of the air intake valve element 1c' to form an air intake valve 1c.

The nipple 1 is formed without the cuts 1a' and 1d, and then both the cuts 1a' and 1d are cut by a cutting device.

The above-mentioned conventional cutting device B is as shown in FIG. During cutting, the push-cutting blade 32 descends and cuts a cross-shaped cut 1a' in the center of the tip of the nipple 1.

The push cutting blade 32 has a cutting edge 3 as shown in FIG.
The blade 2a is formed in a cross shape, and the central part of the cutting edge is sharply pointed. The purpose of sharpening the cutting edge 32a and slanting the angle of the cutting edge in this way is to improve the sharpness and cut the cut 1a' neatly. The two ends are cut diagonally.

However, the notch 1a' whose end is cut diagonally as described above has the disadvantage that tearing tends to proceed from the end, and the notch 1a' may widen with repeated use.

(Technical Problem) The technical problem of the present invention is to maintain the sharpness of the push-cut blade in a cutting device that cuts three or more notches arranged radially at the tip of a baby bottle nipple. , by cutting each end of the notch vertically.

(Means for solving the technical problems) The means taken by the present invention to solve the above-mentioned technical problems include a nipple jig that holds a nipple for a baby bottle, and a nipple jig that holds a nipple for a baby bottle. It consists of a push-cut blade that pushes a notch at the tip that becomes a suction port from the inner surface of the nipple, and the push-cut blade has three or more blade surfaces gathered on one side along the axis of the push-cut blade to form a radial shape. A cutting edge is formed, and this cutting edge protrudes from the center portion toward each blade tip while being inclined.

(Function) According to the above means, the cutting edges of each cutting surface of the push-cutting blade are inclined respectively, and the extreme end of each cutting edge is pointed at an acute angle and protrudes.

When cutting, when the push-cutting blade is advanced toward the inner tip of the nipple held in the nipple jig, each of the extreme ends of the cutting edge first contacts and penetrates the inner surface of the nipple, and then these The end moves forward while cutting the membrane of the nipple vertically. The notch is
As the push-cutting blade moves forward, the cutting edge of each inclined blade surface cuts from each end toward the center.

(Effects) As described above, in this invention, the cutting edge of each cutting surface of the push-cutting blade is sharpened and tilted, so that the sharpness of the push-cutting blade is ensured, and each end of the radial cut is sharpened. The cutting edge of the push-cutting blade can cut vertically. Therefore, it is possible to cut a clean incision at the tip of the nipple and prevent the end from tearing easily.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

A knife jig 6 for attaching and moving the double blades 3 and 5 up and down
It consists of

The nipple jig 2 is fixed on a substrate 7, and a recess 2a is formed on the upper surface of the nipple jig 2, into which the tip of the nipple 1 fits tightly than the collar 1b, so as to hold the nipple 1 in an inverted state. At the same time, a seat 2b for receiving the tip of the nipple 1 during cutting is fitted into the bottom of the recess 2a (the tip of the nipple). The catch seat 2b has a seat surface formed in a concave shape to match the curved surface of the tip of the nipple 1, and has an escape hole 2c in the center for the cutting edge of the push-cutting blade 3 to enter, so that the seat surface is located at some distance from the set tip of the nipple 1. It is to be worn so that it is located at the bottom. Moreover, the air intake valve body 1c on the upper surface of the catch seat 2b
A receiving pin 4 is vertically fixed at a position corresponding to .

The receiving pin 4 has a diameter larger than the inner diameter of the air intake valve body 1c' by a predetermined amount, and has a guide groove 4a in the center of the tip thereof into which the tip of the push-cutting blade 5 is inserted.
Notches are formed in the radial direction of the surface b.

The cutter jig 6 is installed perpendicularly to the nipple jig 2, and its axis is aligned with the jig 2. This cutter jig 6 is moved up and down with a predetermined stroke by an operating mechanism 8, and a chuck 9 provided at the center is equipped with a push-cutting blade 3 for cutting the mouthpiece 1a facing straight down. At the same time, a flat blade 5 for cutting the valve opening is installed at a position directly above the receiving pin 4.

As shown in FIG. 2, the push-cutting blade 3 has a rear end shaped like a shaft so that it can be gripped by a chuck 9, a tip end tapered to a predetermined diameter, and a blade surface 3a formed at the tip end. It has been done.

The number of blade surfaces 3a is determined by the shape of the cut, and when cutting a cross-shaped cut 1a', one side of the four blade surfaces 3a is pressed by the cutting blade 3.
are assembled together along the axis 3c to form a cross-shaped cutting edge 3b. As shown in FIG. 3, the cutting edges 3b are formed so as to protrude from the central part toward the four blade tips while being inclined.
It has double-edged blades.

The push-cutting blade 3 is installed vertically by fitting the rear end into the chuck 9, and can be fixed and removed using a set screw 10.
