The recess 133b is recessed at one end of the body 133a so that the second injection button 134 is inserted. The mounting portion 133c is formed adjacent to the opening of the recess 133b and protrudes from the inner circumference of the recess 133b so that the second injection button 134 is seated.

The second injection button 134 has the injection pipe 132 embedded therein and has a corresponding appearance of the recess 133b. The second spray button 134 is the second spray button 134 is accommodated in the recess 133b and seated on the seating portion 133c, and sliding with the first spray button 133 by the user's pressing operation. Done.

Referring to the drawings, the first injection button 133 is made to rotate relative to the second injection button 134 and the operation groove 135, respectively, sliding of the second injection button 134 by the relative rotation It is formed to take at least a portion of the injection cap 131 to limit. That is, the locking mechanism 140 is operated by the relative rotation of the first injection button 133.

The locking mechanism 140 operates the first and second injection buttons 133 and 134 together when there is no rotation of the first injection button 133, and the first injection button 133 when the first injection button 133 is rotated. ) To limit movement. When the movement of the first injection button 133 is limited, the second injection button 134 accommodated in the first injection button 133 is also restrained.

The locking mechanism 140 includes button protrusions 141a and 141b and guide grooves 142a and 142b.

Button protrusions 141a and 141b protrude from the outer surface of the second injection button 134, and button protrusions 141a and 141b slide to guide the insertion of the second injection button 134 to the recess 133b. Button guide grooves 142a and 142b are formed.

Referring to FIG. 5B, the button protrusions 141a and 141b are provided in plurality so as to be spaced apart from each other along the outer circumference of the second injection button 134 (that is, the circumferential direction of the operation groove 135), and FIGS. 4A and 4C. Referring to FIG. 2, the button guide grooves 142a and 142b are provided in plural along the inner circumference of the first injection button 133 to correspond to the button protrusions 141a and 141b.

When the plurality of button protrusions 141a and 141b are respectively inserted into the plurality of button guide grooves 142a and 142b, the injection holes 137 are disposed to expose the openings of the injection pipe 132 to the outside. This may be implemented by, for example, varying the sizes of the button protrusions 141a and 141b or adjusting the separation distance or the separation angle between the button protrusions 141a and 141b.

The recess 133b is formed to intersect the button guide grooves 142a and 142b, and when the first injection button 133 is rotated to limit the sliding of the second injection button 134, the button protrusions 141a and 141b. Button insertion grooves 143a and 143b are formed. When the button protrusions 141a and 141b are inserted into the button locking grooves 143a and 143b, the second injection button 134 is constrained to the first injection button 133 to operate separately from the first injection button 133. It becomes impossible. The first injection button 133 is constrained to the injection cap 131 by rotation, through which the first and second injection buttons 133 and 134 limit the user's pressing operation.

Hereinafter, a detailed configuration of the locking mechanism 140 for restraining the first injection button 133 to the injection cap 131 will be described.

The locking mechanism 140 includes protrusions 144a and 144b and guide grooves 145a and 145b.

Referring to FIG. 3, the protrusions 144a and 144b are provided in the injection cap 131, and the protrusions 144a and 144b protrude from the inner surface of the operation groove 135. The protrusions 144a and 144b are formed in plural, and the plurality of protrusions 144a and 144b are formed to have different sizes.

4A and 4C, the guide grooves 145a and 145b are formed on the outer surface of the first ejection button 133, and the protrusions 144a and 144b are inserted into the guide grooves 145a and 145b, respectively. Guide the sliding of the injection button 133.

The guide grooves 145a and 145b include guides 146a and 146b and locking grooves 147a and 147b, respectively.

The guides 146a and 146b extend along the sliding direction of the first injection button 133, and the locking grooves 147a and 147b are formed in the direction crossing the guides 146a and 146b. That is, the guide grooves 145a and 145b are formed in the form of "L".

3 and 4A to 4C, the guides 146a and 146b are formed in plural, and the plurality of guides 146a and 146b have different widths to correspond to the plurality of protrusions 144a and 144b. Since the plurality of protrusions 144a and 144b have different sizes, and the plurality of guides 146a and 146b correspond thereto, the second injection button 134 is always inserted into the first injection button 133 at the same position. . However, the present invention is not limited thereto. For example, as the plurality of protrusions 144a and 144b are arranged such that an angle at which the protrusions 144a and 144b are spaced along the circumference of the working groove is an acute angle, the second injection button 134 is always present. It may be combined with the first injection button 133 to the same position.

When the first injection button 133 rotates to limit the sliding of the protrusions 144a and 144b, the protrusions 144a and 144b are inserted into the locking grooves 147a and 147b. Through this, the first injection button 133 is constrained to the injection cap 131 so that sliding is impossible, and the first and second injection buttons 133 and 134 are maintained at a fixed position even when the user presses.

As shown, the portion where the guides 146a and 146b and the locking grooves 147a and 147b meet is made narrower than the width of the locking grooves 147a and 147b. For example, projections protruding in the direction intersecting the insertion direction of the projections 144a and 144b may be formed in the locking grooves 147a and 147b. Through this, the projections 144a and 144b are inserted into the locking grooves 147a and 147b when a rotation force of a predetermined size or more is applied to the first injection button 133.

Referring to the drawings, the guides 146a and 146b are formed of through holes, and the protrusions 144a and 144b pass through the guides 146a and 146b.

5A and 5B, the second injection button 134 is provided with button grooves 148a and 148b into which protrusions 144a and 144b penetrating the guides 146a and 146b are inserted. The button grooves 148a and 148b extend in the same direction as the guides 146a and 146b to guide the sliding of the second injection button 134 on the outer surface of the second injection button 134.

The operation of the ejection button and the locking mechanism will be described below. 6 is a conceptual view showing the operation of the injection device 130 of Figure 1 during the injection operation, Figure 7a and 7b is a conceptual diagram showing the operation of the locking mechanism, respectively.

Referring to FIG. 6, when the user presses the first injection button 133, the guide part 133d of the first injection button 133 moves along the operation groove guide 136 of the injection cap 131. At this time, the second injection button 134 accommodated in the first injection button 133 is moved together. In addition, as the protrusions 144a and 144b slide along the guides 146a and 146b and the button grooves 148a and 148b, the injection pipe 132 mounted to the second injection button 134 is connected to the nozzle assembly 120. 1 to 5b).

7A illustrates an unlocking state before the first and second injection buttons 133 and 134 are locked. FIG. 7B illustrates the locking state. When the first injection button 133 is rotated in the unlocking state, the protrusions 144a and 144b are inserted into the locking grooves 147a and 147b, and the button locking grooves 143a and 143b. ), Button protrusions 141a and 141b are inserted.

As such, when the locking operation, the first injection button 133 rotates relative to the second injection button 134 and the injection cap 131, and sliding of the injection buttons 133 and 134 for the pressing operation by the relative rotation. Because of this limitation, a locking mechanism can be implemented that facilitates injection operation, locking and unlocking.
