Abstract

The present invention relates to a mechanical pencil without a lid that prevents mechanical pencil leads from escaping from a lead container without putting on a separate lid by removing the lid at the end point based on the length direction of the mechanical pencil and replacing the lid with (Fig. 2 15, Fig. 2 16). More particularly, in order to make it easy to take out the lead, put (Fig. 2 17) and press the button so that (Fig. 2 15, Fig. 2 16) is separated, and a nozzle for removing the lead is installed on the side of the mechanical pencil to reduce discomfort when pressing.

Description

Sharp without lid

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sharpener without a lid, and more particularly, to a sharpener that provides convenience by allowing a user to put the sharp core directly into the sharpener without having to open and close the lid.

In the prior art, after taking out the sharp core from the sharp core barrel to the outside of the barrel, the lid of the sharp pencil is opened and the taken out sharp core is put in to charge the sharp core.

However, as shown in FIG. 1 , the conventional sharpener has a problem in that it takes a long time to open and close the container for storing the sharp core, thereby complaining of inconvenience. In particular, in the case of some sharps, problems such as the cap getting caught on the upper surface of the sharpener often caused problems during use.

Therefore, the present invention has been proposed to solve the conventional problems as described above,

An object of the present invention is to reduce the time for inserting the sharp core by replacing the part of the lid that creates such a problem and using the principle of the trap to insert the sharp core into the barrel.

The present invention removes the lid and the eraser of the part connected to the sharp barrel, and installs the sharp core in the shape of a bowl ( FIGS. 2 15 and 2 16 ) so that when the sharp core enters, it easily enters and does not come out easily, and presses the lid to make the sharp core A switch that makes the sharp core come out is installed at the position where the index finger comes on the side instead of the structure that makes it come out.

According to the present invention, when a user inserts and removes a sharp core, the user can easily insert and remove the sharp core without opening and closing the lid.

Figure 2 is a perspective view showing the structure of the present lidless sharp.

As described above, the configuration of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a perspective view illustrating a sharp without a lid;

According to the present invention, in the case of a sharpener manufactured in a certain shape, when the hole in which the sharp is drilled is installed in the form of an inlet of the pot based on the longitudinal direction of the sharp, and the sharp core is inserted, the inlet of the pot serves as a funnel. It helps to go back easily, and after the sharp core enters, it has a narrow exit on the contrary, so it is in a shape that makes it difficult to get out. For the convenience of the user, it is designed so that the sharp core can be pulled out using the button on the side instead of the recessed part on the upper part.

Claims (2)

For sharps manufactured in a certain shape, there is an entrance to the sharp barrel made in the form of a bowl without a lid on the upper part of the lid. There is a device that separates the trap-type sharp shim filter from the sharpener when the button is pressed, so that the sharpener in the sharp shim container can be easily removed.
