Hereinafter, a "cosmetic container production apparatus and cosmetic container" according to an embodiment of the present invention will be described with reference to the drawings.

1 is a conceptual diagram showing the structure of a cosmetic container production apparatus of the present invention.

In the "cosmetic container production apparatus" (hereinafter referred to as the "production device") according to an embodiment of the present invention, a "cosmetic container" (hereinafter, referred to as a'container') is divided into respective components and input, and combined It means a line that produces the container 200 in the final form. In the production apparatus 100 of the present invention, components such as the body 210 and the neck 220 are introduced along an automated production line, and the final product is discharged through a predetermined operation for each step.

The production device 100 is a main body insertion device 110, a neck insertion device 120, an ultrasonic welding machine 130, a control panel 140, a shoulder coupling device 150, a labeling device 160, and a product in the order of parts input. It consists of a discharge device 170. Among them, the control panel 140 is irrelevant to the order of installation of the devices, and may be connected to internal and external control devices to control the operation of each device.

The body injection device 110 means a means for continuously injecting the body 210 constituting the body of the container 200.

Figure 2 is a perspective view showing the structure of a cosmetic container produced using the cosmetic container production apparatus of the present invention, Figure 3 is a perspective view showing a state in which the overcap is removed from the cosmetic container.

As shown in the figure, the container 200 is composed of a body 210, a neck 220, a shoulder 230, and an overcap 240.

The main body 210 is manufactured in a cylindrical or similar shape, and has an open top. The body 210 has a space for accommodating a liquid or gel-type cosmetic therein.

The neck 220 is joined to the upper opening of the main body 210, and a thread is formed on the outer circumferential surface so that the overcap 240 can be coupled. In some cases, a jaw may be formed to adjust the position of the overcap 240 to be screwed. In addition, a passage is formed inside the neck 220 and communicates with the space inside the body 210 below.

The storage capacity of the main body 210 is also changed according to the outer diameter of the approximately cylindrical neck 220. That is, when the storage capacity of the body 210 is large, the outer diameter of the neck 220 and the diameter of the inner passage in the middle are increased, and when the body 210 is small, the size of the inner and outer space of the neck 220 is reduced.

The shoulder 230 has a space through which the neck 220 penetrates, and covers the upper surface of the lower end flange 223 of the neck 220 so that the joint surface of the body 210 and the neck 220 is not visible from the outside. Let it. The shoulder 230 may be used as a decoration to increase the completeness of the container product after the ultrasonic welding process is completed.

The overcap 240 is a component that serves as a lid of the container 200, completely covering the neck 220 and the shoulder 230, and is screwed to the upper thread of the neck 220 so that cosmetic liquid or gel Seal it so that it does not spill.

When the container 200 is produced according to the conventional injection molding process, a thick or swollen trace remains on the bottom surface of the body 210 due to the position of the inlet inside the mold into which the resin is injected. In particular, the trace of the resin inlet located on the bottom surface causes the bottom to rise upward, so that the cosmetic liquid flows from the bottom to the left and right. Also, the bottom surface is not flat, which is disadvantageous in terms of design.

However, as in the present invention, the main body 210 is completely molded inside the injection molding mold, and the neck 220 is joined through a separate subsequent process, thereby removing the constraints of design molding, as well as the smoothness that does not leave other marks on the surface. The container 200 can be manufactured.

On the other hand, Figure 4 is a perspective view showing a state in which the neck and the body are coupled, Figure 5 is a cross-sectional view showing a state in which the neck and the body are coupled, Figure 6 is a cross-sectional view showing the internal structure of the ultrasonic fusing machine for fusing the neck and the body, Figure 7 A perspective view showing a state in which the silver neck and the shoulder are coupled, and FIG. 8 is a cross-sectional view illustrating a state in which the neck and the shoulder are coupled.

As shown in the figure, in order to couple the body 210 and the neck 220, a complementary symmetrical structure must be formed on the surface where the body 210 and the neck 220 are joined to each other. In the present invention, as shown in FIG. 5, a coupling structure is formed on the upper portion of the body 210 and the lower portion of the neck 220, respectively.

The body 210 is provided with a cylindrical body 211 in which an accommodation space is formed. The upper side of the body 211 is open. In addition, the open upper border 212 of the body 211 has an outer diameter relatively smaller than that of the lower side, so that a stepped portion is provided on the outside. The shoulder 230 may be fixed while being seated on the stepped jaw. A coupling groove 213 is formed in the center on the upper surface of the upper border 212. The coupling groove 213 is continuously formed along the circumference on the upper surface of the cylindrical upper border 212.

On the other hand, the neck 220 is manufactured in a form having a thread 222 formed on the outer surface of the upper coupling body 221. The coupling body 221 is substantially cylindrical, and a space is formed therein so that the cosmetic liquid can move. The thread 222 forms a structure for screwing with a thread (not shown) formed on the inner surface of the overcap 240.

A flange 223 having a relatively larger outer diameter is formed on the lower side of the coupling body 221. The diameter of the outer edge of the flange 223 is configured to be the same as the diameter of the edge of the upper edge 212 formed on the body 210. And a coupling protrusion 224 is formed on the bottom surface of the flange 223. The coupling protrusion 224 is formed to correspond to the coupling groove 213 formed in the main body 210, and the coupling protrusion 224 is inserted into the coupling groove 213 so that the body 210 and the neck 220 are coupled. . Due to the structure of the coupling groove 213 and the coupling protrusion 224, the coupling position of the body 210 and the neck 220 does not change, and ultrasonic fusion may be performed at a certain position.

The neck insertion device 120 continuously inputs the neck 220 to be coupled to the body 210 and supplies the neck 220 to be coupled to the body 210 in a one-to-one manner.

In this way, the neck 220 is inserted into the ultrasonic fusing machine 130 while the neck 220 is coupled to the upper portion of the body 210, and the joint surface of the body 210 and the neck 220 made of synthetic resin is heated by ultrasonic waves. As they melt, they are firmly bonded to each other.

The inside of the ultrasonic fusing machine 130 is provided with a jig 131 on which the main body 210 and the neck 220 are seated and fixed. The jig 131 has a space in which the upper portion of the body 210 and the entire neck 220 are inserted, and preferably, a cylindrical shape to wrap and fix the bonding surface where the body 210 and the neck 220 meet from the outside. To form the inner space of

An ultrasonic horn 132 is installed on the inner surface of the jig 131.

Let it. It is preferable that the position of the ultrasonic horn 132 coincide with the side of the bonding surface.

A press 133 is provided on the inner upper surface of the jig 131. The press 133 presses the upper edge of the neck 220 and applies a downward pressure. A pressure of a certain level or higher is applied to the bonding surface between the body 210 and the neck 220 by the pressure of the press 133, and thus, the bonding force between the body 210 and the neck 220 is increased.

The resins heated by ultrasonic waves are combined with each other while melting, so that the neck 220 may be combined with the upper portion of the body 210.

After the fusion of the neck 220 is completed, it is moved to the shoulder coupling device 150 and the shoulder 230 is fitted on the neck 220. In the shoulder coupling device 150, a device for supplying the shoulder 230 is provided so that the shoulder 230 can be fitted on the body 210 to which the neck 220 is fused. It is common that the shoulder 230 and the neck 220 are coupled by force fitting. To this end, protrusions and grooves may be formed at positions corresponding to each other on the outer surface of the neck 220 and the inner surface of the shoulder 230, or an undercut-shaped coupling structure may be formed.

The container 200 in a state where the shoulder 230 is inserted into the neck 220 is transferred to the labeling device 160. The labeling device 160 attaches a label for product description to the outer surface of the main body 210.
