The description will be omitted.

FIG. 1 is a perspective view illustrating a container 200 coupled with a rotary cap 100 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the rotary cap 100 and the disassembly It is a perspective view. 3 is an exploded cross-sectional view of the rotary cap 100 and the container main body 170 taken along line AA of FIG.

1 to 3, the rotary cap 100 according to the present embodiment is engaged with the inlet 172 of the container body 170 to open or close the inlet 172. As shown in FIG. The rotary cap 100 according to the present embodiment includes an inner cap 150 coupled to the inlet 172 of the container body 170 and a slide 130 disposed in the discharge passage 169 of the inner cap 150 And an outer cap 110 positioned around the inner cap 150.

The rotary cap 100 according to the present embodiment is characterized in that the outer cap 110 is rotated to open or close the inlet of the container 200. [ That is, when the outer cap 110 is rotated in one direction, the slide 130 is lifted to close the through hole 111 formed in the outer cap 110 (see FIGS. 4 and 5) The slide 130 is lowered to open the through hole 111 (see FIGS. 6 and 7).

As described above, the rotary cap 100 according to the present embodiment is characterized in that it is convenient to use because the opening of the container 200 can be opened or closed by rotation of the outer cap 110. Also, since the rotary cap 100 according to the present embodiment includes the outer cap 110, the slide 130, and the inner cap 150, the rotary cap 100 is simple in structure and easy to manufacture and assemble. In addition, the rotary cap 100 according to the present embodiment is characterized in that the contents can be discharged in proportion to the pressing force of the container body 170 without discharging the contents at a time.

The inner cap 150 is coupled to the inlet 172 of the container body 170 and has a cylindrical engagement portion 152 and a packing portion 160 having different diameters. The engaging portion 152 is a portion that receives and screws the inlet 172 and the packing portion 160 has a discharge passage 169 and corresponds to a portion where the slide 130 is located.

The engaging portion 152 has a hollow cylindrical shape and receives the inlet 172. A coupling thread 154 is formed on the inner circumferential surface of the coupling portion 152. The engagement threads 154 threadably engage an inlet thread 174 formed around the inlet 172. A locking step 156 is formed on the outer circumferential surface of the engaging part 152. The engaging protrusion 122 formed on the inner peripheral surface of the outer cap 110 is caught by the engaging step 156 so that the outer cap 110 rotatably coupled to the inner cap 150 is not pulled up.

The engaging portion 152 may have a height sufficient to fully accommodate the inlet 172.

An insertion protrusion 158 is provided inside the engaging portion 152. The insertion protrusion 158 protrudes downward with a certain diameter at the center of the upper surface of the engaging portion 152. [ When the inner cap 150 is engaged with the inlet 172, the insertion protrusion 158 is inserted into the interior of the inlet 172 by interference fit so that its outer peripheral surface is in contact with the inner peripheral surface of the inlet 172. It is prevented from flowing out to the joint portion between the inlet 172 and the inner cap 150 in the process of discharging the contents (not shown) by the insertion protrusion 158.

Although the rotary cap 110 according to the present embodiment is illustrated as having the circular cross-section of the engagement portion 152 of the inner cap 150, the present invention is not limited by the cross-sectional shape of the engagement portion 152. For example, according to another embodiment of the present invention, the inner cap may have a cross-section such as an elliptical or polygonal cross-section, and correspondingly the inlet 172 of the container body 170 may also correspond to the inner cap 150 Cross-section.

The packing portion 160 protrudes from the upper surface of the engaging portion 152 and has a smaller diameter than the engaging portion 152. [ The packing part 160 has a hollow cylindrical shape, and a rotation preventing protrusion 164 protrudes upward from the center of the packing part 160. The inner space of the engaging portion 152 and the packing portion 160 is communicated with each other by the discharge passage 169.

The packing portion 160 has a guide protrusion 162 protruding upward from the upper surface of the engaging portion 152. The guide protrusion 162 may have the same diameter as the insertion protrusion 158. 4 to 5, the inner circumferential surface of the guide protrusion 162 may be in contact with the outer circumferential surface of the driving protrusion 118 of the outer cap 110. The driving projection 118 can be inserted into the guide projection 162 by interference fit, thereby preventing the contents from flowing out to the outside. When the outer cap 110 is coupled to the inner cap 150, the upper end of the guide protrusion 162 may have a height that does not contact the inner surface of the outer cap 110.

The packing portion 160 has a rotation preventing protrusion 164 positioned inside the guide protrusion 162. The anti-rotation protrusion 164 has an arc-shaped cross-section and two of the anti-rotation protrusions 164 are spaced apart from each other at a constant interval. A rotation preventing groove 166 is formed between the rotation preventing projections 164. The slide 130 is inserted into the rotation preventing groove 166 to be caught by the rotation preventing protrusion 164 so that the slide 130 does not rotate despite the rotation of the outer cap 110 Only the upward and downward movements are performed.

The height of the rotation preventing protrusion 164 may be formed so that the upper end of the rotation preventing protrusion 164 may contact the inner surface of the outer cap 110 when the outer cap 110 is engaged.

At the center of the rotation preventing projection 164, a discharge passage 169 is provided. The discharge passage 169 is in communication with the inlet 172 formed in the container body 170 and the through hole 111 formed in the outer cap 110 and corresponds to a passage through which the contents are discharged to the outside. A body portion 148 of the slide 130 is inserted into the discharge passage 169 and a plurality of support protrusions 168 are arranged on the inner circumferential surface of the slide portion 130 at regular intervals.

The support protrusion 168 protrudes inward from the inner circumferential surface of the discharge passage 169 and is in contact with the outer circumferential surface of the body portion 148 of the slide 130. The inner diameter of the discharge passage 169 is formed to be larger than the outer diameter of the body portion 148 so that a gap is formed between the two portions so that the contents can be discharged. However, in order to prevent the body part 148 from being shaken, the support protrusions 168 are arranged at regular intervals to come into contact with the outer peripheral surface of the body part 148. [ The contents pass between the support protrusions 168 and the support protrusions 168.

The inner cap 150 may be made of a plastic resin such as PP.

The slide 130 is positioned at the center of the packing part 160 of the inner cap 150 and moves up and down by rotation of the outer cap 110 to close or open the through hole 111. The slide 130 includes a head portion 132, a driving portion 140, and a body portion 148.

The head portion 132 corresponds to the upper portion of the slide 130 and is inserted into the through hole 111 of the outer cap 110 to close the through hole 111. [ The head portion 132 has a truncated cone shape and a head inclined surface 134 is formed around the truncated cone shape. The head inclined surface 134 can push upward the inner inclined surface 115 formed in the through hole 111, so that the contents can not easily flow out to the outside. The head portion 132 may have a head upper surface 136. The head top surface 136 is a circular plane and slightly protrudes from the top surface 112 of the outer cap 110 when the slide 130 closes the through hole 111.

The diameter of the head part 132 may be larger than the diameter of the body part 148. Around the head portion 132, a pair of driving portions 140 are protruded outward so as to face each other.

The driving unit 140 is coupled to the outer cap 110 and corresponds to a portion of the outer cap 110 which is received by the rotational force of the outer cap 110 and does not rotate but moves upward or downward along the inner surface of the driving projection 118. The driving unit 140 includes a side projection 142 and a driving screw 144.

The side projections 142 correspond to the portions protruding from the periphery of the head portion 132. The slide 130 according to the present embodiment is characterized in that a pair of side projections 142 protrude in mutually opposite directions. The side projection 142 is inserted into the rotation preventing groove 166 of the inner cap 150 and corresponds to the portion of the rotation preventing protrusion 164. As described above, since the side projections 142 are caught by the rotation preventing projections 164, the slide 130 does not rotate despite the rotation of the outer cap 110.

The side projections 142 may be formed to have a length enough to project the driving threads 144 provided at the ends thereof to the outside of the rotation preventing protrusions 164.

The driving thread 144 is formed at the end of the side projection 142 and has an arc shape. The drive threads 144 are threaded into the internal threads 120 formed in the drive projection 118 of the outer cap 110. Thus, the rotational force of the outer cap 110 is transmitted to the drive threads 144 through the internal threads 120.

The drive threads 144 and the internal threads 120 may be formed of double-threaded threads. As a result, the movement distance of the slide 130 can be increased by the rotation of the outer cap 110, and the slide 130 can be prevented from moving when the outer cap 110 is not rotated by raising the frictional force. Of course, the drive threads 144 and the internal threads 120 may also be formed by single row or three or more rows of threads.

The side groove 146 is a groove formed in the periphery of the head portion 132 and serves to enlarge the gap between the head portion 132 and the rotation preventing projection 164 (see FIGS. 5 and 7).

The body portion 148 is a portion extending downward from the lower end of the head portion 132, and has a cylindrical shape. The body portion 148 is located inside the discharge passage 169 and comes into contact with the support projection 168 partially.

Although the slide 130 according to the present embodiment is illustrated as having two driving portions 140 protruding in opposite directions to each other, the present invention is not limited by the number and arrangement position of the driving portion 140. The rotary cap according to another embodiment may have one or three or more driving portions.

The slide 130 may be formed of a plastic resin such as LDPE.

The outer cap 110 has a hollow cylindrical shape and its lower surface is open. The outer cap 110 is located around the inner cap 150 and is exposed to the outside. Accordingly, the user can turn the outer cap 110 clockwise or counterclockwise to close or open the through-hole 111 by moving the slide 130 up and down.

The outer cap 110 has a top surface 112 and a circumferential surface 116.

The upper surface 112 is formed with a through hole 111 through which the contents are exposed at the center in a circular shape. A central protrusion 114 is formed around the periphery of the portion where the through hole 111 is formed. An inner inclined surface 115 is formed on the inner surface of the through hole 111 and the central projection 114. The inner inclined surface 115 is pressed by the head inclined surface 134 of the slide 130, which prevents the foreign matter from flowing out.

The circumferential surface 116 forms a circumference of the outer cap 110 and has a circular cross section. The circumferential surface 116 has a diameter sufficient to completely accommodate the inlet 172 of the container body 170. A locking protrusion 122 is formed on the inner circumferential surface of the circumferential surface 116. The engaging protrusion 122 is caught by the engaging step 156 formed around the engaging portion 152 of the inner cap 150 so that the outer cap 110 can rotate without being detached from the inner cap 150 do.

The locking protuberance 122 has a lower inclined surface 124 that has a gentle slope angle to allow it to pass easily through the locking step 156. The locking protrusion 122 has an upper inclined surface 126 which has a larger inclination angle than the lower inclined surface 124 so that the locking protrusion 122 is not easily released from the locking step 156 do.

Fine protrusions (not shown) may be formed around the circumferential surface 116 to allow the user to easily rotate the outer cap 110.

A driving projection 118 is provided inside the outer cap 110. The drive projection 118 has a hollow cylindrical shape extending downward from the upper surface 112, and the lower surface thereof is opened. The center of the drive projection 118 may be formed to coincide with the center of the through hole 111. [

4 to 5, the driving projection 118 is positioned between the guide projection 162 and the driving portion 140 of the slide 130. [ An internal thread 120 is formed on the inner peripheral surface of the driving projection 118. The internal threads 120 are threaded with drive threads 144 formed on the drive of the slide 130. Internal threads 120 may also be formed with double threaded threads, similar to drive threads 144.

The outer cap 110 may be formed of a plastic resin such as PP.

Hereinafter, the rotary cap 100 according to the present embodiment will be described in more detail with reference to FIGS. 3 to 7. FIG.

Fig. 4 is a cross-sectional view taken along the line AA in Fig. 1, illustrating a state in which the through hole 111 is closed, and Fig. 5 is a cross-sectional view taken along the line BB in Fig. 1 illustrating a state in which the through hole 111 is closed. 4 illustrates a state in which the driving unit 140 is inserted into the rotation preventing groove 166. As shown in FIG.

4 to 5, when the contents (not shown) accommodated in the container body 170 of the container 200 are not used, the slide 130 is moved upward, (111) is closed. Particularly, since the head inclined surface 134 of the slide 130 presses the inner inclined surface 115 formed around the through hole 111, the contents can not easily flow out to the outside.

It is noted that the inner cap 150 is coupled to the inlet 172 by screwing and in particular the insertion protrusion 158 of the inner cap 150 is inserted into the inlet 172. The slide 130 is located in the discharge passage 169 formed at the center of the inner cap 150.

Referring to FIG. 5, it can be seen that the discharge passage 169 is always open. That is, although the body portion 148 of the slide 130 is inserted into the discharge passage 169, since the interval between the inner peripheral surface of the discharge passage 169 and the outer peripheral surface of the body portion 148 is constant, Provide a passage through which can be discharged. Of course, the portion where the support projection 168 is formed in the discharge passage 169 is closed.

4 to 5, when the outer cap 110 is rotated in one direction (for example, clockwise), the driving projection 118 also rotates together to transmit rotational force to the driving unit 140 of the slide 130 . That is, since the internal thread 120 formed on the driving projection 118 and the driving thread 144 of the driving unit 140 are screwed together, the rotational force of the external cap 110 is transmitted to the internal thread 120 and the driving thread 144 144 to the slide 130. Since the slide 130 is inserted into the rotation preventing groove 166 and can not rotate, the slide 130 is rotated by the rotation of the outer cap 110, . Due to the descent of the slide 130, the through hole 111 formed in the outer cap 110 is opened as shown in FIGS.

FIG. 6 is a cross-sectional view taken along the line AA in FIG. 1, illustrating a state in which the through hole 111 is opened, and FIG. 7 is a cross-sectional view taken along the line BB in FIG. 1, illustrating a state in which the through hole 111 is opened. 6 illustrates a state in which the driving unit 140 is inserted into the rotation preventing groove 166. As shown in FIG.

6 to 7, it can be seen that the slide 130 is lowered by the rotation of the outer cap 110, and the through hole 111 is opened. In other words, it can be seen that the head inclined surface 134 of the slide 130 is spaced apart from the inner inclined surface 115. Thus, the contents (not shown) can be discharged to the outside while sequentially passing through the inlet 172 of the container, the discharge passage 169, and the through hole 111 (see the arrow direction).

6 and 7, when the container body 172 is pressed, the contents are discharged to the outside of the through hole 111 by the pressure. At this time, since the slide 130 does not move due to the frictional force generated between the drive threads 144 of the slide 130 and the internal threads 120 of the outer cap 110, the contents are not discharged at the same time, So that it can be discharged proportionally.

6 and 7, when the outer cap 110 is rotated in the other direction (for example, counterclockwise), the driving projection 118 rotates in the same direction and transmits the rotational force to the driving unit 140 As a result, the slide 130 rises along the inner peripheral surface of the outer cap 110.

The container 200 including the rotary cap 100 according to the present embodiment has a container body 170. The rotary cap 100 is screwed into an inlet 172 provided in the container body 170. An inlet thread 174 is formed around the inlet 172. A stopper 176 is provided at a lower end of the inlet 172. The stopper 176 is caught by the inner circumferential surface of the inner cap 150 to prevent the inner cap 150 from rotating.

The container 200 including the rotatable cap 100 according to the present embodiment may include various contents for cosmetics, cosmetics or hair. In addition, the container 200 according to the present embodiment can be used for various purposes such as a beverage container or a bucket. The container according to another embodiment of the present invention may have various shapes (for example, a rectangular parallelepiped or a cube) of the container body, and the inlet may be formed at various positions of the container body.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be understood that the invention may be varied and varied without departing from the scope of the invention.
