Abstract

PROBLEM TO BE SOLVED: To provide a cartridge type content extruding container extruding a content without any time lag.SOLUTION: In conjunction with an event that a cartridge 1 is removed from a body cylinder 2, threaded engagement between a female screw 7 of a female screw member 5 and a male screw 17 of a moving body 4 is released, a first elastic body 19 presses the moving body 4 forward in an axial direction and moves it to a forward limit. When a new or another cartridge 1 is inserted into the body cylinder 2, the moving body 4 comes into contact with a piston 48 in the cartridge 1 and pushed back rearward in the axial direction against the pressing force of the first elastic body 19. Then, in conjunction with mounting of the cartridge 1 in the body cylinder 2, the female screw 7 and the male screw 17 are threadedly engaged to allow the moving body 4 to advance. In that state, the piston 48 and the moving body 4 are in the contact state so as to, in a repetitive rotating operation by a user after replacement of the cartridge, be able to exclude a content L without any time lag.

Description

  The present invention relates to a cartridge-type content extrusion container.

  Conventionally, a cartridge-type cosmetic pressure container described in Patent Document 1 below is known as a cartridge-type content extrusion container. This cartridge-type cosmetic pressure container is formed by detachably attaching a cartridge to a holder, which is a main body container, and the cartridge includes a cosmetic storage chamber that stores cosmetics, and a cosmetic in the cosmetic storage chamber. And a pair of elastic arc-shaped sections formed by providing a pair of split grooves facing the rear end, with a female screw provided on the inner periphery thereof. Further, in the holder, a screw rod having a male screw that engages with the female screw on the outer periphery is arranged via a push spring, and a return spring for pulling back the screw rod is arranged.

  And in this cartridge type cosmetic pressure container, when the cartridge is mounted on the holder, the elastic arcuate section hits the inner peripheral surface of the inner cylinder of the holder and elastically bends radially inward, thereby The female screw of the arc-shaped piece and the male screw of the screw rod are screwed together, and the female screw and the male screw are rotated relative to each other by the relative rotation of the cartridge and the holder, which is the operation of rotating the screw rod by the user. The cosmetics are pushed out and pushed forward. On the other hand, when the cartridge is pulled out from the holder, the arc-shaped piece is elastically returned to the outside in the radial direction so that the screwing is released and the screw rod is pulled back to the initial position in the holder by the screwing release. It has become.

Japanese Patent No. 2786592

  However, in Patent Document 1, when the cartridge is replaced with a new one filled with unused cosmetics, the piston in the new cartridge is used even if the screw rod is pulled back to the initial position in the holder. Is in the retreat limit, the screw rod can begin to push out the piston quickly when the user pulls out and rotates.For example, if you own multiple cartridges containing different color cosmetics, When the cartridge is replaced with a cartridge of a different color at a position advanced from the initial position (when replaced), the distance between the screw rod pulled back to the initial position and the piston advanced from the initial position Therefore, there is a problem that many rotations are required before the screw rod starts to push out the piston, and there is a time lag before the cosmetic comes out.

  Therefore, an object of the present invention is to provide a cartridge type content extruding container capable of extruding the content without time lag when the user rotates and rotates the cartridge after replacing the cartridge.

  The cartridge-type content extruding container according to the present invention is a cartridge-type content extruding container in which the cartridge containing the contents is detachably attached to a main body container containing a mechanism for pushing out the contents. A storage chamber that can store an object, a piston that is slidable in the storage chamber and that pushes out the content, and an opening that allows the content that is pushed out by the piston to go outside. An opening that can be inserted, a female screw member having a female screw provided on the inner surface, and a male screw that engages with the female screw is provided on the outer surface, and moves forward by the relative rotation of the male screw and the female screw to push out the piston. And a first elastic body that presses the moving body forward in the axial direction, and the female screw and the male screw are interlocked with the cartridge being pulled out of the main body container. When the combination is released and the cartridge is inserted into the main body container, the moving body abuts on the piston and is pushed back in the axial direction against the pressing force of the first elastic body, so that the cartridge is mounted on the main body container. The female screw and the male screw are engaged with each other.

  According to such a cartridge type content extruding container, in conjunction with the extraction of the cartridge from the main body container, the screwing of the female screw of the female screw member and the male screw of the moving body is released, and the moving body is It is pushed forward in the axial direction by the elastic body 1 and moves to the forward limit. Here, for example, when a new cartridge or another cartridge that contains different color contents and has been used last time is inserted into the main body container, the moving body comes into contact with the piston in the cartridge and the first elastic It is pushed back in the axial direction against the pressing force of the body, and in the case of a new cartridge, it is returned to the backward limit, and in the case of another cartridge that has been used last time, it is returned to the previous position while contacting the piston. The female screw of the female screw member and the male screw of the moving member are screwed together with the mounting of the cartridge on the main body container, and the moving member can be advanced by relative rotation of the female screw and the male screw. It becomes. In this state, since the piston and the moving body are in contact with each other, the contents can be pushed out without a time lag when the user rotates the cartridge after replacing the cartridge.

  Here, the female screw member moves forward in the axial direction in conjunction with the extraction of the cartridge from the main body container, and forcibly expands the diameter of the female screw member that has started moving forward in the axial direction. If the screw release portion for releasing the screw of the male screw is provided, the screw release can be surely performed when the cartridge is extracted from the main body container.

  In addition, it is preferable to include a second elastic body that presses the female screw member forward in the axial direction and moves the female screw member forward in the axial direction in conjunction with the cartridge being extracted from the main body container. When such a configuration is employed, the female screw member can be reliably moved forward in the axial direction with a simple configuration called an elastic body.

  Further, when the cartridge is inserted into the main body container, the female screw member contacts the rear end portion of the cartridge and moves rearward in the axial direction, and forcibly reduces the diameter of the female screw member that moves rearward in the axial direction. In addition, when the screwing forcing member for screwing the female screw and the male screw is provided, the screwing can be surely performed when the cartridge is inserted into the main body container and mounted.

  Further, when the female screw member is pressed rearward in the axial direction according to the insertion of the cartridge even after the female screw and the male screw are screwed together, the female screw member can be moved rearward in the axial direction corresponding to the pressing. Is preferred. When such a configuration is adopted, when the cartridge is inserted, the female screw member is reduced in diameter from the expanded state, and when the female screw of the female screw member is screwed with the male screw, the female screw is not screwed completely. Since the member is fixed to the moving body (integrated) and then the female screw member is pressed rearward by the cartridge, the female screw member moves rearward in the axial direction by the amount corresponding to the pressing. Can be further inserted, and the moving body fixed to the female screw member at that time can also move rearward. For this reason, the cartridge is completely attached to the main body container while avoiding that the piston is pushed forward by the moving body that does not move in the axial direction and moves forward and the contents are inadvertently ejected from the opening of the cartridge. it can.

  Here, as a configuration of the female screw member that preferably exhibits the above action, specifically, when expanding the diameter, the female screw member has a plurality of arc portions that form an arc shape when viewed in the axial direction along the substantially circumferential direction. There is a configuration in which a female screw is provided on the inner surface, and when the diameter is reduced, the arc portion is continuous so as to form a substantially circular shape when viewed in the axial direction.

  Further, as a preferable configuration of the female screw member, specifically, a configuration that exhibits a substantially C shape in the axial direction view when the diameter is expanded can be given. According to this, the female screw member can be simply configured.

  Further, as a configuration of the screw release portion that preferably exhibits the above action, specifically, the arc portion of the female screw member that has started to move forward in the axial direction in conjunction with the cartridge being pulled out from the main body container. A configuration in which a screw-release protrusion that enters between each other and expands the diameter of the female screw member is used.

  Moreover, if the screwing forcing member has a screwing release protrusion on its inner surface, it can be made compact.

  As described above, according to the present invention, it is possible to provide a cartridge-type content extruding container that can extrude the content without time lag when the user rotates and rotates after the cartridge is replaced.

In this state, as shown in FIG. 2, the female screw 7 of the female screw member 5 is screwed with the male screw 17 of the moving body 4, and in this state, the female screw member 5 is moved forward by the cartridge 1. In a state in which this is blocked (details will be described later), the second coil spring 31 is pressed forward in the axial direction via the pressing member 30.

  As shown in FIG. 1, the cartridge 1 includes a cartridge cylinder 43 that stores the liquid cosmetic L, an inner cylinder 44 that is attached to the inner peripheral surface of the distal end portion of the cartridge cylinder 43 and extends forward, and a distal end portion of the cartridge cylinder 43. An outer cylinder 45 that is mounted on the outer peripheral surface of the cartridge 1 and extends forward, and an application body 46 that forms the tip of the cartridge 1 are roughly provided.

  The cartridge cylinder 43 is configured in a substantially cylindrical shape, and a substantially cylindrical tail plug 47 is attached to the rear end thereof. A piston 48 made of an elastic body is press-fitted into the rear end side of the cartridge cylinder 43, and the piston 48 abuts against the tail plug 47, so that the space in front of the piston 48 in the cartridge cylinder 43 becomes liquid cosmetic. The storage chamber 49 is configured to store L. The piston 48 is for extruding the liquid cosmetic L toward the distal end side, and is slidable in the accommodation chamber 49. Further, when the cartridge 1 is inserted into the main body cylinder 2 and attached to the tail plug 47, the rear end surface of the tail plug 47 abuts on the front end surface of the female screw member 5, and the female screw member 5 is moved rearward. Move.

  The cylinder hole of the inner cylinder 44 communicates with the accommodation chamber 49 in the cartridge cylinder 43, and a pipe member 50 that communicates with the cylinder hole of the inner cylinder 44 is attached to the front end side so as to extend forward. The application body 46 is mounted so as to surround the tip end side of the pipe member 50. Here, the application body 46 is a brush and extends forward. The opening 51 at the tip of the pipe member 50 is an opening for taking out the liquid cosmetic L pushed out by the piston 48 to the outside.

  The outer cylinder 45 is configured to be cylindrical at the rear end side and is attached to the cartridge cylinder 43, and the front side of the outer cylinder 45 is a tapered truncated cone-shaped cylinder whose inner and outer diameters gradually decrease toward the tip. . Then, the brush 46 passes through the circular opening at the tip of the outer cylinder 45 and protrudes forward. The brush 46 is bundled by the tip of the outer cylinder 45 and the tip of the brush 46 has a sharpened shape. The On the outer peripheral surface of the rear end portion of the outer cylinder 45, a male screw 52 that engages with the female screw 27 of the main body cylinder 2 is provided for detachably mounting the cartridge 1 on the main body cylinder 2.

  The cartridge 1 is attached to the main body cylinder 2 by inserting the rear side of the collar portion 53 into the main body cylinder 2 and the male screw 52 is screwed into the female screw 27 of the main body cylinder 2. The tail plug 47 of the cartridge 1 comes into contact with the distal end surface of the female screw member 5 and presses the female screw member 5 backward.

  Note that a ball 91 for stirring the liquid cosmetic L is disposed in the storage chamber 49, and a cap 54 for protecting the writing brush 46 is detachably attached to the cartridge 1.

  According to the cartridge-type content extruding container 100 configured as described above, when the main body cylinder 2 or the cartridge 1 and the operation cylinder 3 are relatively rotated by the user, the above-described screwing mechanism, rotation stopper, and ratchet mechanism are used. Then, the moving body 4 moves forward with a click feeling, and the liquid cosmetic L is pushed out by the piston 48 and discharged from the opening 51 to be applied by the writing brush 46.

  Next, as shown by a solid line in FIG. 4, the cartridge in which the piston 48 is advanced to an intermediate position in the axial direction by use is replaced with a new cartridge that is unused and filled with liquid cosmetics of different colors. The case will be described.

  When the cartridge 1 is pulled out from the main body cylinder 2, the female screw member 5 pressed forward by the second coil spring 31 starts to move forward in the axial direction from the state shown in FIGS. As shown in FIG. 15, the screw release protrusion 9 of the screwing forcing member 8 enters the dividing line 37 from the inclined surface 41 of the V-shaped cutout 40 of the female screw member 5, and as shown in FIGS. Further, the female screw member 5 is forcibly expanded in diameter to form a substantially C shape when viewed in the axial direction, and the screwing of the female screw 7 of the female screw member 5 and the male screw 17 of the moving body 4 is released. At this time, since the cartridge 1 does not exist, the moving body 4 is pushed forward in the axial direction by the first coil spring 19 and moves to the forward limit as shown in FIGS. 4 and 5.

  When the new cartridge 1 is inserted into the main body cylinder 2, the piston 48 in the new cartridge 1 is in the backward limit as shown by the phantom line in FIG. Immediately contact the tip of the moving body 4 at the forward limit.

  Here, the frictional force of the piston 48 against the inner wall of the cartridge cylinder 43 is set to be larger than the pressing force (biasing force) of the first coil spring 19. For this reason, the moving body 4 is pushed back in the axial direction against the pressing force of the first coil spring 19 by the piston 48 and pushed back to the retreat limit.

  When the cartridge 1 is mounted on the main body cylinder 2, the female screw member 5 is pressed backward from the state shown in FIG. 15 by the tail plug 47 of the cartridge 1, and the hemispherical protrusion 34 of the female screw member 5 is formed. The inclined surface 41 of the V-shaped notch 40 of the female screw member 5 guided by the guide portion 33 of the screwing forced member 8 is inclined to the rear side of the V-shaped screw release protrusion 9 of the screwed forced member 8. As shown in FIG. 14, the circular arc portions 39, 39 are connected so as to form a substantially circular shape when viewed in the axial direction, whereby the female screw 7 of the female screw member 5 and the moving body are moved. The four male screws 17 are screwed into an initial state shown in FIG. 1, and the moving body 4 can be moved forward by the relative rotation of the female screw 7 and the male screw 17. In this state, since the piston 48 and the moving body 4 are in contact with each other, the liquid cosmetic L can be pushed out without a time lag when the user rotates and rotates after the cartridge is replaced.

  Further, when the cartridge being used is replaced with, for example, another cartridge that contains liquid cosmetics of different colors and has been used last time, the female screw is extracted as the cartridge 1 is pulled out from the main body cylinder 2. 7 and the male screw 17 are disengaged, the moving body 4 moves to the forward limit, and another cartridge 1 that has been used last time is inserted into the main body cylinder 2 to advance by the previous use. The moving body 4 moved to the forward limit comes into contact with the piston 48, and the moving body 4 is pushed back in the axial direction against the pressing force of the first coil spring 19 by the piston 48 at the previous position. The female screw 7 and the male screw 17 are screwed together. In this state, since the piston 48 and the moving body 4 are in contact with each other, the liquid cosmetic L can be pushed out without time lag as in the case of the new cartridge 1.

  In addition, as shown in FIG. 3, when replacing the cartridge in which the moving body 4 is pushed out to the forward limit and the liquid cosmetic L has been used up with a new cartridge or another cartridge that has been used last time, As the cartridge 1 is withdrawn from the main body cylinder 2, the female screw 7 and male screw 17 are unscrewed, and a new cartridge 1 or another cartridge 1 that has been used before is inserted into the main body cylinder 2. As a result, the moving body 4 that has moved to the forward limit due to the use of the liquid cosmetic L is pushed back in the axial direction against the pressing force of the first coil spring 19 by the piston 48, and is a new cartridge 1. In the case of another cartridge that has been used last time, it moves to the previous position, and the female screw 7 and the male screw 17 are screwed together. In this state, since the piston 48 and the moving body 4 are in contact with each other, the liquid cosmetic L can be pushed out without time lag.

  As described above, in the present embodiment, the threading of the female screw 7 of the female screw member 5 and the male screw 17 of the movable body 4 is interlocked with the cartridge 1 being extracted from the main body cylinder 2 constituting the main body container. Is released, and the moving body 4 is pushed forward in the axial direction by the first coil spring 19 and moves to the forward limit. For example, a new cartridge 1 or another cartridge 1 that has been used last time is placed in the main body cylinder 2. When inserted, the moving body 4 comes into contact with the piston 48 in the cartridge 1 and is pushed back in the axial direction against the pressing force of the first coil spring 19, and interlocked with the cartridge 1 being attached to the main body cylinder 2. Then, the female screw 7 of the female screw member 5 and the male screw 17 of the moving body 4 are screwed together, and the moving body 4 can be moved forward by the relative rotation of the female screw 7 and the male screw 17, and in this state, Piston 48 and moving body 4 Since the contact, upon feeding rotation operation by the user after the cartridge replacement, it can be pushed out without any time lag liquid cosmetic L.

  Further, in this embodiment, when the cartridge 1 is inserted, the female screw member 5 is reduced in diameter from the expanded state, and when the female screw 7 of the female screw member 5 is screwed with the male screw 17, it is completely screwed. Even if the female screw member 5 is previously fixed to the moving body 4 (integrated) and then the female screw member 5 is pressed backward by the cartridge 1, the female screw member 5 is correspondingly pressed. When the female screw member 5 is pushed rearward in the axial direction according to the insertion of the cartridge 1 even after the female screw 7 and the male screw 17 are screwed together (before completely screwing), Since it is possible to move rearward in the axial direction corresponding to the pressing, the cartridge 1 can be further inserted, and the moving body 4 fixed to the female screw member 5 also moves rearward at that time. it can. For this reason, the cartridge 1 is inserted into the main body cylinder 2 while avoiding that the piston is pushed forward by the moving body that does not move in the axial direction and moves forward, and the liquid cosmetic is inadvertently ejected from the opening of the cartridge. Can be installed completely.

  Further, in the present embodiment, in conjunction with the cartridge 1 being extracted from the main body cylinder 2, the female screw member 5 that is about to move forward in the axial direction is forcibly expanded in diameter, so that the female screw 7 and the male screw Since the screw release protrusion 9 for releasing the screw 17 is provided, the screw release can be reliably performed when the cartridge 1 is pulled out from the main body cylinder 2.

  In addition, a second coil spring 31 is provided that presses the female screw member 5 forward in the axial direction and moves the female screw member 5 forward in the axial direction in conjunction with the cartridge 1 being pulled out from the main body cylinder 2. Therefore, the female screw member 5 can be reliably moved forward in the axial direction with a simple configuration called a coil spring.

  When the cartridge 1 is inserted into the main body cylinder 2, the female screw member 5 that contacts the rear end portion of the cartridge 1 and moves rearward in the axial direction is forcibly reduced in diameter, and the female screw 7 and the male screw 17. Therefore, when the cartridge 1 is inserted into the main body cylinder 2 and mounted, the screwing can be surely performed.

  Further, since the female screw member 5 is configured to have a substantially C shape when viewed in the axial direction when the diameter is expanded, the female screw member 5 can be simply configured.

  Moreover, since the screwing forced member 8 has the screwing release protrusion 9 on its inner surface, it can be made compact.

  Furthermore, in the present embodiment, the female screw 7 and the male screw 17 are not sequentially screwed from one side to the other side along the axial direction, but all the screws along the axial direction are almost all. There is an advantage that they can be screwed together.

  In the case where the threading is released only by elastic return of the arcuate section to the outside of the diameter as in the prior art without providing the threading release projection 9 for forcibly releasing the threading, There arises a problem that the cartridge cannot be pulled out without the arc-shaped piece being elastically restored, and a problem that the screw is broken by being forcibly removed.

  Incidentally, the female screw member 5 is urged forward by the second coil spring 31 which is the second elastic body. For example, the tail plug 47 which is the rear end side of the cartridge 1 and the front end side of the female screw member 5 are used. For example, when the cartridge 1 is inserted into the main body cylinder 2 and the female screw member 5 is pushed backward, the cartridge 1 and the female screw member 5 are engaged by the engaging portion. When the cartridge 1 is extracted from the main body cylinder 2, the female screw member 5 moves forward in a state of being engaged with the cartridge 1, and the female screw 7 and the male screw 17 are moved by the V-shaped screw release protrusion 9. When the screw 1 is released and the cartridge 1 is further extracted from the main body cylinder 2 with the female screw member 5 being caught by the screw release protrusion 9, the engagement between the female screw member 5 and the cartridge 1 is released. May be adopted.

  Here, as particularly preferred, the screwing forcing member 8 has a screwing release projection 9 on its inner surface, but the screwing release projection 9 may be on the main body cylinder 2 side. Moreover, if it is a screwing cancellation | release part which can cancel | release screwing, it will not be limited to a screwing cancellation | release protrusion.

  In addition, here, the first and second coil springs 19 and 31 are used as being particularly preferable. However, any elastic body having the same action may be used.

  Here, the application body for applying to the application part such as the skin is a brush, but the tip surface of the outer cylinder 45 of the cartridge 1 is the application surface, and this application surface communicates with the storage chamber 49. An opening may be provided as a discharge port for the liquid cosmetic L, and an application body such as a chip or a comb may be used around the discharge port.

It is the point which connected via the connection parts 57 and 57 which comprise a dogleg shape in the axial direction view, and the connection part 57 has elasticity by being made thin also here.

  When the cartridge 1 is pulled out from the main body cylinder 2, the female screw member 55 is pressed forward by the second coil spring 31, and the screw release protrusion 9 (in this second embodiment, the screw release protrusion is 2) enters the gap of the U-shape of the connecting portion 57 of the female screw member 55, and as shown in FIG. 17, the arc portions 56, 56 are separated from each other in the vertical direction, whereby the male screw 17 of the moving body 4 The screwing is released.

  On the other hand, when the cartridge 1 is inserted into the main body cylinder 2 and the female screw member 55 moves rearward and is reduced in diameter by the screwing forcing member 8, the connecting portion 57 looks like it is crushed in the left-right direction in FIG. The portions 56 and 56 are continuous so as to form a substantially circular shape when viewed in the axial direction, and thereby the screwing of the moving body 4 with the male screw 17 is performed. Therefore, the same operation and effect as the female screw member 5 of the first embodiment can be obtained.

  18 is a perspective view showing a female screw member of a cartridge type content extruding container according to a third embodiment of the present invention, and FIG. 19 is a front view of the female screw member shown in FIG. 18 as viewed from the front side.

  The female screw member 65 of the third embodiment is different from the female screw member 55 of the second embodiment in that the connecting portion 57 is eliminated and the arc portion 56 that forms a semicircular shape when viewed in the axial direction is divided into two. .

  Here, the arc portion 56 has elasticity so that the curved outer peripheral surface further spreads outward, and can move in the axial direction so as to stick to the inner peripheral surface of the screwing forcing member 8. Even if the connecting portion 57 of the second embodiment is not provided, substantially the same operations and effects as the female screw member 55 of the second embodiment are exhibited.

  It should be noted that a groove for entering the arc portion 56 and guiding the arc portion 56 so as to be slidable may be provided in the screwing forcing member 8 so that the arc portion 56 of the female screw member 65 can be smoothly moved. More preferable.

  20 is a perspective view showing a female screw member of a cartridge type content extruding container according to a fourth embodiment of the present invention, and FIG. 21 is a front view of the female screw member shown in FIG. 20 as viewed from the front side.

  The female screw member 75 of the fourth embodiment is different from the female screw member 55 of the second embodiment in that the semicircular arc portion 56 is viewed in the axial direction, and the 1/4 arc shape arc portion is viewed in the axial direction. 76, and these arc portions 76 are connected by a connecting portion 77 having an arc shape in the axial direction and being thin and elastic.

  Here, the inner peripheral surface of the screwing forcing member 8 is configured to be reduced in diameter from the front side toward the rear side (a configuration having a frustoconical inner peripheral surface), and the cartridge 1 is removed from the main body cylinder 2. In the extended state, the female screw member 75 is pressed forward by the second coil spring 31 and is positioned on the inner peripheral surface of the front side of the screwing forcing member 8, and is shown in FIGS. 20 and 21. Thus, when the circular arc portions 56 and 56 are separated from each other in the radial direction, the screwing of the movable body 4 with the male screw 17 is released.

  On the other hand, when the cartridge 1 is inserted into the main body cylinder 2 and the female screw member 75 moves rearward and is positioned on the inner peripheral surface of the rear side of the screwing forcing member 8, the female screw member 75 is connected to each arc portion 76. And the four arc portions 76 to 76 are connected so as to form a substantially circular shape when viewed in the axial direction, whereby the screw 4 is engaged with the male screw 17 of the movable body 4. Therefore, there are substantially the same operations and effects as the female screw member 55 of the second embodiment.
