Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sticking-out mechanism for a stick-shaped feeding container such as a correction stick, a color core, and a lipstick, and a cap used for writing instruments such as a ball pen, a mechanical pencil, a fountain pen, and a marking pen.

[0002]

[Prior Art]

 This type of conventional cap is generally removably fitted to the adhered portion by fitting or screwing.

[0003]

[Problems to be solved by the device]

 However, the cap by fitting is fitted with a click feeling so that it cannot be easily removed, so it is difficult to remove, and the cap by screwing is difficult to remove but difficult to remove. .

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the mechanism of the present invention forms the chevron portion 3 and the trough portion 4 on the outer peripheral portion of the adherend 1, and the chevron portion 3 and the trough portion 4 on the inner peripheral portion of the cap 2, respectively. A trough portion 5 and a chevron portion 6 to be fitted are provided, and the cap 2 is crested to the outer peripheral portion of the adherend 1, and the trough portions 3 and 4 and the troughs and chevron portions 5 and 6 are fitted to be removable. It will be fitted.

[0005]

[Action]

 When the cap 2 is removed, when the cap 2 is rotated, the cap 2 is moved along the inclined sides of the trough 5 and the trough 6 into which the chevron 3 and the trough 4 fit, respectively, and the cap 2 is covered. It can be easily removed from the attachment part 1. Further, when the cap 2 is attached, when the cap 2 is inserted into the adhered portion 1 and pushed, the mountain portion 3 and the valley portion 4 are fitted in the fitting directions along the inclined sides of the valley portion 5 and the mountain portion 6, respectively. Therefore, the cap 2 can be easily fitted and attached to the adherend 1.

【Example】

 FIG. 1 is a sectional view showing the construction of one embodiment of the mechanism of the present invention, FIG. 2 (A) is the front portion of the adherend in the present invention, and FIG. 2 (B) is a perspective view of the cap thereof. 3 is an explanatory diagram of the operation of the present invention. In FIG. 1 and FIG. 2, reference numeral 1 denotes an adhered portion to which a cap is fitted, and includes, for example, a base cylinder 1A and a rotation guide cylinder 1B of a container for feeding out a rod-shaped object. The rod-shaped object 7 held on the rod-shaped object support 8 can be retracted from the tip of the rotary guide cylinder 1B by rotating the rotation guide cylinder 1B with respect to the base cylinder 1A. Reference numeral 2 denotes a cap, which includes an outer cap 2A fitted on the base cylinder 1A and an inner cap 2B fitted on the rotation guide cylinder 1B. A chevron portion 3 and a trough portion 4 are formed on the outer peripheral portion of the base cylinder 1A, and a trough portion 5 and a trough portion 6 which are fitted to the chevron portion 3 and the trough portion 4, respectively, are formed on the inner peripheral portion of the outer cap 2A. Is provided. The outer cap 2A and the inner cap 2B of the cap 2 are fitted to the outer peripheral portion of the base cylinder 1A and the outer peripheral portion of the rotation guide cylinder 1B, respectively, with ridges, valleys 3, 4 and valleys, ridges 5, 6 respectively. Then, it is detachably fitted.

In the above structure, when the cap 2 is removed, when the cap 2 is rotated, the trough portion 5 and the trough portion 3 of the base cylinder 1A into which the trough portion 5 and the trough portion 6 of the outer cap 2A are fitted, respectively. It is possible to easily remove the outer cap 2A and the inner cap 2B forming the cap 2 from the base cylinder 1A and the rotation guide cylinder 1B forming the adherend 1 by moving in the detaching direction along the inclined sides of the. Become.

Further, when the cap 2 is attached, the outer cap 2A and the inner cap 2B forming the cap 2 are fitted into the base cylinder 1A and the rotation guide cylinder 1B forming the adherend 1 and pushed, respectively. The mountain-shaped portion 6 and the valley-shaped portion 5 of 2A move in the fitting direction along the inclined sides of the valley-shaped portion 4 and the mountain-shaped portion 3 of the base cylinder 1A, respectively, and the outer cap 2A and the inner cap 2B forming the cap 2 are removed. It can be easily fitted and attached to the base cylinder 1A and the rotation guide cylinder 1B constituting the adherend 1.

[0009]

[Effect of the device]

 As described above, according to the present invention, the mountain portion 3 and the valley portion 4 are formed on the outer peripheral portion of the adherend 1, and the mountain portion 3 and the valley portion 4 are fitted on the inner peripheral portion of the cap 2, respectively. A trough portion 5 and a chevron portion 6 are provided, and the cap 2 is mounted on the outer peripheral portion of the adherend 1 with the crests, trough portions 3, 4 and troughs, chevron portions 5, 6 to be detachably attached. Since it is fitted, the cap 2 can be easily attached by inserting it into the adhered part 1 and pushing it, and by easily rotating the cap 2 onto the adhered part 1 and pulling it out with an extremely small force. It can be removed.
