Description

Technical Field

[0001] The present invention relates to a retractable container that presses a knob to project a receptacle of a container from a main body or retract it into the main body.

Background Art

[0002] Generally, a container is used to store contents received therein. Recently, various retractable structures have been disclosed so that the contents can be easily used and stored. Patent Document 1 relates to a pen-type cosmetic container that extrudes contents from a nozzle through the forward movement of a piston, and discloses a structure that allows the contents injected from the nozzle to be extruded or recovered by the forward / backward movement of the piston. However, in such a structure, since the configuration of the piston for forward / backward movement occupies most of the space inside the container, there is a disadvantage that the volume of the contents decreases. In addition, in the case of the above-described configuration, in order to increase the volume of the contents, there is a problem that the length of the container must be increased as a whole or the volume must be increased. Patent Document 2 relates to a knock-press type writing instrument, in which a large number of gears or components having similar functions are respectively molded inside for knock operation, and then these components are combined for operation. In the case of the knock-press type writing instrument, since there are many components for projecting and retracting the pen core, the coupling structure at the time of assembly is complicated, productivity is reduced, and it is difficult to manage the components, so there is a problem that the unit price increases. In addition, since the size of the pen core of the knock-press type writing instrument is determined, it has a disadvantage that it can be used only for one type of product. Furthermore, in the above-known registered patent, since the knock operation configuration for the projection and retraction of the receptacle is located inside the container, there is a problem that it is difficult to utilize the internal space of the container.

[0008] Throughout this specification, when a part is said to be "connected, joined or coupled" to another part, this includes not only the case where it is "directly connected, joined or coupled", but also the case where it is "indirectly connected, joined or coupled" with another member interposed therebetween. Further, when a part is said to "include" a certain component, this means that, unless otherwise stated to the contrary, it does not exclude other components, but can further include other components.

[0009] The terms used in this specification are merely used to describe specific embodiments and are not intended to limit the present invention. Singular expressions include plural expressions as well, unless the context clearly indicates otherwise. Terms such as "include" and "have" in this specification are intended to specify the presence of the features, numbers, steps, operations, components, parts, or combinations thereof described herein, and it should be understood that the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof is not precluded in advance.

[0010] Preferred embodiments of the present invention will be described in detail together with the drawings so that those having ordinary knowledge in the technical field to which the present invention pertains can easily implement it.

[0011] FIG. 1 is a cross-sectional view showing the retractable container 1000 of the present invention.

[0012] The retractable container 1000 includes a main body 1100 and a knob 1300. To explain the operation of the retractable container 1000, a receptor (not shown) formed inside the main body 1100 is protruded from the main body or retracted into the main body by the knocking operation of the knob 1300. The knocking operation requires the compression and restoring force of a spring (not shown). The present invention is characterized in that the configuration required for the knocking operation is formed outside the main body 1100 so that the internal space of the main body 1100 can be utilized.

[0013] In addition, the knob 1300 includes an integrally formed knocking operation part 1350, a pressing part 1330, and a locking protrusion 1335. In the case of the knob 1300, each component is formed as one molded product to simplify the structure, thereby improving productivity and reducing manufacturing costs.

[0014] In the following description, the front end is described with reference to the entrance / exit 1170 side of the main body 1100, and the rear end is described as the side into which the knob 1300 is inserted.

[0015] FIG. 2 is a perspective view showing the main body 1100 shown in FIG. 1. FIG. 3A is an enlarged view showing the front of the body cam 1110 located in the main body 1100 shown in FIG. 2. FIG. 3B is a front view showing an enlarged view of the back of the main body 1100 shown in FIG. 3A.

[0016] The main body 1100 includes a body cam 1110, a second guide slit 1130, an insertion port 1150, and an entrance / exit 1170. The main body 1100 is integrally formed, and a space for receiving a receptor (not shown) and a spring (not shown) is formed inside. The entrance / exit 1170 is formed on one side of the main body 1100, and the insertion port 1150 into which a receptor (not shown) and a knob 1300 can be inserted is formed on the other side. Since the main body 1100 does not include components necessary for the knocking operation for protruding and retracting the receptor (not shown), the internal space can be freely utilized. The expression "the internal space of the main body 1100 can be freely utilized" means that it can be used without limitation to the size (thickness or length) of the receptor (not shown).

[0017] Referring to FIGS. 2 to 3A, the body cam 1110 includes a first guide slit 1111, a guide bar 1112, an auxiliary guide slit 1113, a connecting portion 1115, a protrusion 1117, and an incision 1119.

[0018] The body cam 1110 has a lever shape including a plurality of slits in the main body 1100 so as to be able to correspond to the position change of the knocking operation unit 1350. In particular, the body cam 1110 can be formed in a cantilever type in which one end of the lever is connected to the main body 1100 and the other end is not supported. Such a body cam 1110 controls the position (protruding from the main body or retracting into the main body) of the receptor (not shown) while moving along the knocking operation unit 1350 by the knocking operation of the retractable container 1000.

[0019] The first guide slit 1111 is a through hole formed in the longitudinal direction of the main body 1100 and receives the knocking operation unit 1350. The knocking operation unit 1350 moves in the longitudinal direction of the main body 1100 by the knocking operation. The guide bar 1112 is characterized in that it is a lever formed on one or both sides around the first guide slit 1111. When the guide bar 1112 is formed on one side in a single form, one end of the guide bar 1112 is fixed to the main body 1100 on one side of the first guide slit 1111, and the other end of the guide bar 1112 is not supported, and it can be formed in a cantilever type. When the guide bar 1112 is formed on both sides in a double form, two guide bars 1112 of the cantilever type are formed on both sides with the first guide slit 1111 as a reference. At this time, each end not supported by the two guide bars 1112 may be connected and formed.

[0020] The auxiliary guide slit 1113 is a hole formed between the guide bar 1112 and the main body 1100. The auxiliary guide slit 1113 is a hole formed so that the guide bar 1112 can move along the knock operation part 1350. Also, the width of the auxiliary guide slit 1113 defines a play that can correspond to the position change of the guide bar 1112.

[0021] The connecting part 1115 connects the two guide bars 1112. The connecting part 1115 is formed so that it can maintain the pressure applied to the guide bar 1112 when the width between the two guide bars 1112 increases or decreases. When the position of the knock operation part 1350 changes due to a knock operation, the connecting part 1115 connects the two guide bars 1112 without breaking even when the width between the two guide bars 1112 widens or at least the height of one guide bar 1112 changes. In the present invention, the connecting part 1115 is shown as being formed in a U shape, but it can be implemented by deforming the connecting shape and the thickness of the connecting part so as to be different (thinner or thicker) so that the pressure can be maintained by connecting the two guide bars 1112 arranged at separated positions.

[0022] The protrusion 1117 protrudes from the guide bar 1112 in the direction of the first guide slit 1111. The protrusion 1117 is characterized in that it moves along the knocking part 1350 during the knocking operation. In particular, the protrusion 1117 may be moved or fixed along a plurality of inclined surfaces and a plurality of steps formed in the knocking part 1350. The surface of the protrusion 1117 corresponding to the knocking part 1350 may be formed as an inclined surface so that the protrusion 1117 does not deviate from the moving direction of the knocking part 1350 during the knocking operation. In the present invention, the protrusions 1117 are formed in the direction of the first guide slit 1111 at symmetrical positions on the two guide bars 1112 arranged at a distance from each other, but the present invention may be modified so that at least one protrusion 1117 is arranged at a distance from each other depending on the inclined surfaces and steps of the knocking part 1350.

[0023] The cutout 1119 is formed between the first guide slit 1111 and the insertion hole 1150 at the rear end of the body 1100. The cutout 1119 provides a passage for the knock operating part 1350 to move when the knob 1300 is inserted into or separated from the body 1100. The cutout 1119 may be formed in a diagonal shape such that the end connected to the insertion hole 1150 increases in width in the direction of the insertion hole 1150 so that the knob 1300 can be easily inserted into the body 1100. In addition, the cutout 1119 may offset pressure applied to the connection part 1115 during the knock operation due to play formed between the first guide slit 1111 and the insertion hole 1150.

[0024] The second guide slit 1130 is a through hole formed in the longitudinal direction of the main body 1100, into which a part of the knob 1300 may be inserted and fixed. A locking protrusion 1335 may be inserted into the second guide slit 1130. Although FIG. 3B shows that the second guide slit 1130 is formed on the rear end of the main body 1100 on the opposite side to the body cam 1110, it may be formed on the outer circumferential surface of the main body 1100 at a position that does not overlap with the body cam 1110.

[0025] FIG. 4A is an enlarged perspective view showing the knob 1300 shown in FIG. 1. FIG. 4B is a side view of the knob 1300 shown in FIG. 4A.

[0026] The knob 1300 includes an extension part 1310, a pressing part 1330, and a knocking operation part 1350. The knob 1300 is molded in one mold, and in particular, the knocking operation part 1350 is integrally molded. After the knob 1300 is inserted into the insertion port 1150 of the main body 1100, it moves to the front end or the rear end by a knocking operation. In the knob 1300, the knocking operation part 1350 is formed at a connecting part that connects the pressing part 1330 and the extension part 1310. That is, in the present invention, since the configuration required for the knocking operation is not formed inside the main body 1100, various receptors (not shown) can be applied and used without limitation to the size, thickness, and length of the receptor (not shown).

[0027] After the knob 1300 is connected to the main body 1100, the extension part 1310 enables the retractable container 1000 to be inserted into a pocket or the like and carried.

[0028] The pressing part 1330 includes a pressing surface 1331, a pressing main body 1332, a receiving hole 1333, a locking protrusion 1335, a first engaging protrusion 1337, and a second engaging protrusion 1339. The pressing part 1330 can be a part to which the pressure required for the knocking operation is applied.

[0029] The pressing surface 1331 is a part that is pressed by the user's hand during the knocking operation. Looking at the operating relationship in the retractable container 1000 of the present invention, by pressing the pressing surface 1331, a receptor (not shown) can be protruded from the entrance 1170, and by pressing the pressing surface 1331 again, the receptor (not shown) can be retracted into the entrance 1170.

[0030] The pressing main body 1332 is an area that extends from the pressing surface 1331 and is inserted into the insertion port 1150 of the main body 1100. The pressing main body 1332 includes a locking protrusion 1335 so as to be able to fix the main body 1100 and the knob 1300. The pressing main body 1332 includes a receptor receiving space formed in the center so that a receptor (not shown) can be coupled.

[0031] Further, the pressing body 1332 is inserted into the second guide slit 1130 and includes a locking projection 1335 for fixing the main body 1100 and the knob 1300. The locking projection 1335 includes a receiving hole 1333 formed around the locking projection 1335 in the pressing body 1332. Therefore, when the locking projection 1335 is inserted into the main body 1100, after being inserted in a state of being pressed by the main body 1100, the locking projection 1335 is fixed while being fitted into the second guide slit 1130. Conversely, when removing the knob 1300 from the main body 1100, the locking projection 1335 is pressed so as to be released from the second guide slit 1130. The locking projection 1335 is characterized in that it is of a cantilever type in which one end is connected and fixed to the pressing body 1332 so that its shape changes when pressed and it can be restored to its original position when the pressing is released, and the other end is not fixed. The locking projection 1335 can have a diagonal shape in which the front end face becomes higher as it goes to the rear end portion so that it can be easily pressed by the main body 1100 when entering the inside of the receiving hole 1333.

[0032] The receiving body receiving space of the pressing body 1332 includes a first engaging projection 1337 and a second engaging projection 1339. The pressing body 1332 is formed with a first engaging projection that is inserted and fixed to the inner peripheral surface of the content receiving portion of the receiving body (not shown) so that various receiving bodies (not shown) can be applied and used without limitation to the size, thickness, and length of the receiving body (not shown). Further, on the inner peripheral surface of the pressing body 1332, a second engaging projection 1339 is formed to be fitted adjacent to the outer peripheral surface of the receiving body (not shown). For example, when the cross section of the receiving body (not shown) is narrow, it can be used by fitting it to the first engaging projection 1337. And when the cross section of the receiving body (not shown) is wide or the receiving body is blocked, the outer peripheral surface of the receiving body can be fitted to the second engaging projection 1339 for use. Also, in the receiving body receiving space of the pressing body 1332 of the present invention, receiving bodies (not shown) having a long or short length can be used depending on the arrangement of the first engaging projection 1337 and the second engaging projection 1339. Therefore, the utilization degree of the receiving body (not shown) is increased.

[0033] The container of the present invention is characterized by including a first engaging protrusion formed so that a receptor is inserted and fixed inside the pressing body.

[0034] The container of the present invention is characterized in that a second engaging protrusion is formed on the inner peripheral surface of the pressing body, and the outer peripheral surface of the inserted receptor is fitted and fixed.

[0035] FIG. 5 is a perspective view showing an enlarged view of the knock operating portion 1350 shown in FIG. 4A. FIG. 6A is a view showing the protrusion moving direction in the knock operating portion shown in FIG. 4A. FIG. 6B is a view showing the moving points 2 to 7 of the protrusion 1117 that moves from the basic position 1 of the retractable container 1000 to during the knock operation before the receptor (not shown) is retracted into the main body 1100. At this time, the basic position 1 means a state in which the protrusion 1117 is arranged at a distance from the knock operating portion 1350.

[0036] The knock operating portion 1350 includes a first slope 1351, a cam guide 1353, a first step 1355, a second slope 1357, a second step 1359, a placement portion 1361, a third step 1363, a third slope 1365, and a fourth step 1367. The knock operating portion 1350 is characterized in that a plurality of slopes and a plurality of steps are integrally formed.

[0037] The knock operating portion 1350 moves from the rear end to the front end or from the front end to the rear end with respect to the longitudinal direction of the main body 1100 by a knock operation. At this time, the protrusion 1117 of the body cam 1110 is located on the slope or step of the knock operating portion 1350. Looking at the arrangement of the plurality of slopes and steps in the knock operating portion 1350, the protrusion 1117 seems to be adjacent to the outer extension portion 1310 with respect to the main body 1100, or is arranged at the original position (main body 1100 position). As a result, in the retractable container 1000 of the present invention, the configuration related to the knock operation is not arranged in the space inside the main body 1100, and the utilization rate of the internal space is improved.

[0038] The knock actuating part 1350 may be formed in the same shape on both sides corresponding to the body cam 1110. In the present invention, the knock actuating part 1350 is formed on both sides, but it is characterized in that the knock operation can be performed even if it is formed only on one side.

[0039] The first slope 1351 is formed as an inclined surface that spreads in the width direction. The first slope 1351 is configured such that the protrusion 1117 moves in a direction opposite to the pressure applied to the knock operation. While the protrusion 1117 moves along the inclined surface of the first slope 1351 that spreads in the width direction, the width between the two guide bars 1112 increases.

[0040] The cam guide 1353 is disposed above the first slope 1351 and is formed to protrude from the inclined surface of the first slope 1351. The cam guide 1353 prevents the protrusion 1117 from detaching when the first slope 1351 enters between the protrusions 1117.

[0041] The first step 1355 is formed to extend in the longitudinal direction of the main body 1100 from the first slope 1351. The first step 1355 guides the protrusion 1117 to the end of the first step 1355 while maintaining the width between the two guide bars 1112 at the point 2 where the first slope 1351 ends in a direction opposite to the pressure applied to the pressing surface 1331.

[0042] The second step difference 1359 is formed inside a virtual line (not shown) extending from the first step difference 1355. The second step difference 1359 further includes an inclined surface or a guide groove. The second step difference 1359 may be formed such that the inclined surface protrudes in the width direction from the lower end to the upper end in order to prevent the protrusion 1117 from detaching during the knocking operation process. Since the inclined surface of the second step difference 1359 is disposed inside a virtual line (not shown) extending from the first step difference 1355, the distance between the two guide bars 1112 of the body cam 1110 is restored. The pressure applied to the pressing surface 1331 during the knocking operation is maximized in the second step difference 1359, and a receptor (not shown) compresses a spring (not shown) to the maximum. At this time, the protrusion 1117 is positioned (3) adjacent to the end of the second step difference 1359. The expression "the pressure applied to the pressing surface 1331 during the knocking operation is maximized" means a state in which most of the knobs 1300 are retracted inside the main body 1100. At this time, when the front end of the knocking operation portion 1350 abuts against the front end portion of the first guide slit 1111 or the locking protrusion 1335 abuts against the front end portion of the second guide slit 1130, the knob 1300 stops moving forward.

[0043] After the pressure applied to the pressing surface 1331 reaches the maximum during the knocking operation and the pressure is removed (one knocking operation is completed), the knob 1300 is pressed against the rear end portion of the main body 1100 by the reaction of a spring (not shown). In such a state, the advancing direction of the protrusion 1117 is switched (4).

[0044] The second slope 1357 is characterized in that an inclined surface is formed adjacent to the cam guide 1353 in the second step difference 1359. The second slope 1357 allows the protrusion 1117 to move along the inclined surface in the second step difference 1359 after the advancing direction is switched. While moving along the second slope 1357, the protrusion 1117 raises the two guide bars 1112 and the connecting portion 1115 connecting them adjacent to the extension portion 1310.

[0045] In FIG. 6A, point 5 where the protrusion 1117 is disposed on the placement portion 1361 is a fixed state where the knob 1300 is no longer pushed to the rear end, indicating a state where the receptor 1500 protrudes outside the main body 1100 and can be used. That is, the placement portion 1361 hooks the protrusion 1117 to fix the knob 1300 to the main body 1100. The placement portion 1361 may be formed on the side surface of the cam guide 1353 and may be formed as an inclined surface whose width increases toward the upper part adjacent to the extension portion 1310 so that the protrusion 1117 does not come off. Further, the portion of the protrusion 1117 that contacts the inclined surface of the placement portion 1361 can be formed as an inclined surface corresponding to the inclined surface of the placement portion 1361.

[0046] In FIG. 6A, point 6 shows a state where the knob 1300 is pressed to retract a receptor (not shown) protruding outside the main body 1100 into the main body 1100, and at this point, the traveling direction of the protrusion 1117 is switched.

[0047] The third step 1363 moves the protrusion 1117 in the longitudinal direction of the main body 1100 according to the pressure applied to the pressing surface 1331 by the knocking operation. The third step 1363 is formed as an inclined surface, and the protrusion 1117 passes through a third slope 1365 connecting the third step 1363 and the fourth step 1367 and moves to a position 6 adjacent to the fourth step 1367.

[0048] The fourth step 1367 connects the third step 1363 and the extension portion 1310. Further, the fourth step 1367 switches the traveling direction of the protrusion 1117 toward the front end of the knock operation portion 1350 and moves (7) it during the process of pushing the knob 1300 into the rear end of the main body 1100. In FIG. 6A, point 7 shows the position of the protrusion 1117 in a state where if the knob 1300 is not further pressed during the knocking operation, the knob 1300 is pushed into the rear end of the main body 1100 by the reaction of a spring (not shown).

[0049] In FIG. 6A, point 8 shows the position of the protrusion 1117 in a state where the receptor 1500 has retracted into the main body 1100, which is the same as the initial point 1 before operation.

[0050] In the retractable container 1000 of the present invention, a knock operating portion 1350 of a knob 1300, which is a main configuration for a knock operation, is formed outside a main body 1100. Therefore, as described above, the space inside the container can be freely used. When the utilization degree increases in the container main body 1100 as in the present invention, receptors (not shown) having various lengths and thicknesses can be used, so that it is possible to improve the inconvenience that the container becomes unnecessarily long or only a specific receptor has to be used.

[0051] Further, in the retractable container 1000 of the present invention, the knock operating portion 1350 is integrally formed on the knob 1300, and by integrally forming a body cam 1110 that moves along the knock operating portion 1350 on the main body 1100, the structure is simplified. That is, the retractable container can be used for writing instruments, cosmetics, sanitary products, diagnostic kits, etc., and can be used in various fields such as medical, industrial, and stationery.

[0052] For example, when the retractable container 1000 is applied to a retractable writing instrument, there is no limitation on the size, thickness, or length of the pen core to be inserted, so the internal space can be freely utilized. Specifically, the retractable container 1000 can be applied and used for pen cores with different thicknesses or different lengths. Further, since the retractable container 1000 can be molded with one mold for the retractable configuration, productivity is improved and production costs can be reduced.

[0053] Also, when the retractable container 1000 of the present invention is applied to a retractable cosmetic case in which a brush or puff retracts, there is no limitation on the size, thickness, or length of the receptor to which the brush, puff, etc. inserted into the retractable container are connected and the cosmetics are received, so the internal space can be freely utilized.

[0054] When the retractable container 1000 of the present invention is applied to a toothbrush storage container in which a toothbrush retracts as another embodiment, there is no limitation on the size, thickness, or length of the toothbrush to be inserted, so the internal space can be freely utilized. Therefore, the container can be used for portable purposes.

[0055] When the retractable container 1000 of the present invention is applied to a retractable diagnostic device in which a stick for absorbing a sample retracts as another embodiment, there is no limitation on the size, thickness, or length of the diagnostic device to be inserted, so the internal space can be freely utilized. Specifically, the retractable container 1000 can be applied and used for diagnostic devices with different thicknesses or lengths of the diagnostic device.

[0056] FIG. 7 is a diagram showing another embodiment of the retractable container. In the present invention, in the case of a product that does not need to be inserted into a pocket or the like and carried around, the extension part 1310 can be removed and the appearance can be changed to have a smooth shape for implementation.

[0057] FIG. 8A is a plan view (A), a front view (B), and a bottom view (C) showing another embodiment of the retractable container, and FIG. 8B is a perspective view showing an enlarged knob of FIG. 8A.

[0058] FIGS. 8A and 8B have the same function related to the knock operation of protruding a receptor (not shown) received inside the main body 1100 to the outside of the main body 1100 by pressing the knob 1300 in FIGS. 1 to 6B, so this will not be described in detail. Compared with the configuration of FIGS. 1 to 6B, FIGS. 8A and 8B have different structures of the knock operation part 2350 including the locking protrusion 1335 and the corresponding main body 2100, and the part related to this will be mainly described.

[0059] The knock operation part 2350 is inserted into the first guide slit 2111 of the main body 2100 through the insertion port 2150. The knock operation part 2350 is characterized in that a receiving hole 2333 is formed around it, one end is connected to the pressing main body 2332, and the other end is of a cantilever type that is not supported.

[0060] Since the knock operating part 2350 is inserted while being pressed inside the pressing body 2332, it will not get caught on the main body 2100. After the knock operating part 2350 is inserted, it recovers from the state of being pressed inside the pressing body 2332 and protrudes outside the main body 2100. At this time, the knock operating part 2350 gets caught on the first guide slit 2111 so that the knob 2300 does not come off from the main body 2100. When removing the knob 2300 from the main body 2100, the knock operating part 2350 is pressed inside the pressing body 2332 so that it does not get caught on the main body 2100. At this time, the knob 2300 is removed from the main body 2100 through the insertion port 2150.

[0061] The above description of the present invention is for illustrative purposes. In addition, those having ordinary knowledge in the technical field to which the present invention pertains will be able to understand that it can be implemented in other specific forms without changing the technical idea and essential features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative in all aspects and not restrictive. For example, each component described as a single type may be implemented in a distributed or divided manner, and similarly, components described as being distributed or divided may also be implemented in a combined form within the scope understood by an ordinary technician.

[0062] The scope of the present invention is indicated by the claims described below, and it should be construed that all changes or modified forms derived from the meaning and scope of the claims and their equivalent concepts are included in the scope of the present invention.
