  By the way, in the past, with regard to the attachment / detachment structure of the lid, container body, and added parts that are rotated with respect to each other, a reverse screw is used, or one screw fitting is used for one screw fitting with a concave fitting. However, the reverse screw is required to operate in the opposite direction to the general right-hand screw operation. There were inconveniences such as difficult to understand operation. Further, even if the tightening strength of the two screw fittings is changed by the concave protrusion fitting, the screw fitting that should be tightened is not necessarily firmly tightened, and the tightening is loosened. There was an inconvenience that co-rotation cannot be avoided.

  The present invention has been devised in view of the above-described conventional problems, and each has a structure that can be detached by rotating, so that it can be properly detached even if it is rotated in the same direction. However, it aims at providing the liquid substance storage container which can prevent co-rotation reliably.

A liquid storage container according to the present invention includes a container main body that stores a liquid substance in an extractable manner, an extraction port that has an extraction port, and is screwed into the container main body via a screw portion so as to be loosened and loosened. A locking portion that is provided between the extraction cylinder and the container main body and detachably engages with the extraction cylinder . a withdrawal operation by twisting operation of rotating is guided in the mounting state together with detachably mounted to said thimble so as to seal the said spout, the locked state by the locking unit, to the extraction tube And a cap that is in a detachable state in the process of being detached from the extraction cylinder, and the locking portion includes a convex portion formed to protrude radially outward from the container body, and the extraction A bullet formed in a cylinder that is elastically deformable in the radial direction. One piece is formed to protrude inward in the radial direction of the extraction cylinder, and is clamped over the convex portion with elastic deformation of the elastic piece by tightening the extraction cylinder into the container body. Then, by loosening the extraction cylinder with an operating force over the convex part, the elastic piece is formed with a locking projection that is released from the convex part with elastic deformation of the elastic piece, and between the container body and the extraction cylinder. Is characterized in that a stopper portion is formed to prevent the extraction cylinder from rattling around the container body after the locking projection is locked to the convex portion.

  The liquid material storage container according to the present invention has a structure that can be detached and attached by being rotated, so that it can be properly detached even by a rotating operation in the same direction, It can be reliably prevented.

Hereinafter, a preferred embodiment of a liquid container according to the present invention will be described in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 4, the liquid material storage container according to the present embodiment basically includes a container body 1 that stores liquid material in an extractable manner and an extraction port 2. An extraction tube 4 that is screwed together loosely through a screw portion 3, a locking portion 5 that is provided between the extraction tube 4 and the container body 1 and that removably locks them, and guide means a withdrawal operation by twisting operation of rotating the left or right with respect to extraction tube 4 with the mounting operation for the extraction cylinder 4 by the operation down by 6 is guided, detachably mounting the spout 2 into the extraction tube 4 so as to blockade And a cap 7 that holds the locked state by the locking portion 5 in a state of being attached to the extraction cylinder 4 and that can be detached in the process of being detached from the extraction cylinder 4. A convex portion 19 formed to project radially outward from the container body 1, and an extraction cylinder The elastic piece 22 is formed so as to be elastically deformable in the radial direction so as to protrude inward in the radial direction of the extraction cylinder 4, and the elastic piece 22 is elastically deformed by tightening the extraction cylinder 4 into the container body 1. In the meantime, it is locked over the convex part 19 and is released from the convex part 19 with the elastic deformation of the elastic piece 22 by loosening the extraction cylinder 4 by operating force over the convex part 19. The stopper part 25 which consists of the protrusion 20 and prevents the extraction cylinder 4 from rattling around the container body 1 after the locking protrusion 20 is locked to the convex part 19 between the container body 1 and the extraction cylinder 4. Is formed and configured.

  The container main body 1 is formed in a hollow cylindrical shape whose bottom is sealed, and a liquid material such as a liquid cosmetic such as lotion or milk is accommodated therein. The container body 1 is formed with an extraction neck 10 at the top and a reduced diameter portion 11 at the top, with two upper and lower first step portions 8 and 9 at the upper end thereof. The neck 10 is formed with an opening 12 that can extract a liquid material. On the other hand, the extraction cylinder 4 is formed in a hollow cylinder shape whose upper end is blocked by the top surface part 13, and an annular skirt part 15 is formed below and a cylinder part 16 is formed above via a single step part 14. Is done. The top surface portion 13 has an extraction port 2 at the center thereof, protrudes upward around the extraction port 2, and an annular spout portion 17 hangs downward and removably fits into the opening 12 of the container body 1. An annular fitting portion 18 is formed. The extraction cylinder 4 has its stepped portion 14 overlapped with the first stepped portion 8 of the container body 1 so that the cylinder portion 16 covers the extraction neck portion 10 and the annular skirt portion 15 covers the reduced diameter portion 11. Mounted on the container body 1.

  A screw portion 3 is formed between the container body 1 and the extraction cylinder 4. Specifically, a male screw 3a is formed on the outer peripheral surface of the extraction neck portion 10 of the container body 1, and is screwed into the inner peripheral surface of the cylindrical portion 16 of the extraction tube 4 so as to be tightened and loosened to the male screw 3a. The extraction screw 4 is detachably attached to the container main body 1.

  The locking portion 5 is provided between the extraction neck portion 10 of the container body 1 and the cylindrical portion 16 of the extraction tube 4 so as to be detachably locked. The locking portion 5 is protruded radially inward from the outer peripheral surface of the extraction neck portion 10 and protruded radially outward from the convex portion 19 and the inner peripheral surface of the cylindrical portion 16. And a locking projection 20 that is detachably locked to the convex portion 19. The convex part 19 is provided in the annular step part 21 formed in the lower end of the extraction neck part 10 just above the 1st level | step-difference part 8 of the container main body 1 and the downward direction of the external thread 3a. The locking projection 20 is provided on an elastic piece 22 formed on the lower end of the cylindrical portion 16 that is directly above the stepped portion 14 of the extraction tube 4 and faces the annular stepped portion 21. The elastic piece 22 is formed to be elastically deformable in the radial direction of the cylindrical portion 16 by a U-shaped slit 23 formed in the cylindrical portion 16.

  And this latching | locking part 5 fastens the latching protrusion 20 over the convex part 19 with the elastic deformation of the elastic piece 22 by fastening the cylinder part 16 to the extraction neck part 10 via the screw part 3. Thus, relative rotation between the extraction cylinder 4 and the container main body 1, particularly relative rotation in the loosening direction of the screw portion 3 is prevented. On the other hand, when the locking projection 20 is moved over the convex portion 19 with the elastic deformation of the elastic piece 22 and the screw portion 3 is loosened, the locking projection 20 is detached from the convex portion 19. The extraction cylinder 4 can be removed from the container body 1.

  In the illustrated example, the convex portion 19 and the locking projection 20 are formed at one location around the extraction neck portion 10. However, the number of installation locations can be set as appropriate. Further, when the tube portion 16 is tightened to the extraction neck portion 10 (the screw portion 3 is a right screw and the extraction tube 4 is rotated to the right), the convex portion 19 that faces the locking projection 20 is An inclined surface 24 is formed so that the locking projection 20 can smoothly get over the elastic piece 22 with elastic deformation of the elastic piece 22.

Further, a stopper 25 is provided between the container body 1 and the extraction cylinder 4 in order to prevent the cylinder 16 from rattling around the extraction neck 10 after the locking projection 20 is locked to the convex part 19. It is formed. The stopper portion 25 is roughly matched with the height position of the convex portion 19 and the locking projection 20, and is formed on the outer periphery of the annular step portion 21 so as to protrude outward in the radial direction, and the cylindrical portion 16. And a restraining protrusion 27 that is formed so as to protrude radially inward at the lower end inner periphery of the lower end of the member and abuts against the restraining convex portion 26 immediately after the locking portion 5 is locked . If the size is set so that the locking projection 20 gets over the convex portion 19 at the position where the screw portion 3 is closed, the locking projection 20 and thus the extraction cylinder 4 will not rattle.

  The cap 7 is formed in a hollow cylindrical shape whose upper end is sealed from the peripheral side wall portion 28 and the top plate portion 29. The cap 7 is suspended from the top plate portion 29 so that the cap portion 30 is inserted into the spout portion 17 to seal the extraction port 2 on the inside, and the outer periphery of the spout portion 17 is freely detachable. An annular fitting portion 31 that is fitted and holds the cap 7 to the extraction cylinder 4 is formed. Between the cap 7 and the extraction cylinder 4, a guide means 6 is provided for guiding the operation of detaching the cap 7 from the extraction cylinder 4.

The guide means 6 includes a V-shaped groove 33 formed in the vertical direction by recessing a stepped portion 32 formed on the outer peripheral surface of the tube portion 16 of the extraction tube 4, and the peripheral side wall of the cap 7. V-shaped projections 34 formed so as to protrude in the vertical direction on the inner peripheral surface of the portion 28, and when the extraction tube 4 is pushed down with the cap 7 covered from above, a V-shape is formed. When the protrusion 34 fits into the V-shaped groove 33 instead of the stepped portion 32, the mounting operation of the cap 7 with respect to the extraction tube 4 is guided, while the cap 7 in the mounted state is left and right with respect to the extraction tube 4. twisting operation to rotate in either result, the cap 7 is lifted to extract tube 4 along the tapered forming the outer contour of the V-shaped grooves 33 and V-shaped projection 34, thereby leaving the operation of the cap 7 Will be guided That. The guide means 6 composed of the V-shaped groove 33 and the V-shaped protrusion 34 is partially formed in the circumferential direction of the extraction cylinder 4 and has a dimension that is extremely shorter than the length of the thread of the screw portion 3. 7 is configured to be detached from the extraction cylinder 4 with a short operation stroke.

  In particular, the peripheral side wall portion 28 of the cap 7 is a tube in which the elastic piece 22 is formed in a state where the fitting portion 31 is fitted to the spout portion 17 of the extraction tube 4 and the cap 7 is attached to the extraction tube 4. The cap 7 is formed so as to cover and cover the lower end of the portion 16, whereby the cap 7 prevents elastic deformation of the elastic piece 22 in a state of being attached to the extraction tube 4, and is separated from the extraction tube 4 by the guide means 6. The elastic piece 22 is allowed to be elastically deformed by being extracted above the elastic piece 22 in the process of being done.

  Specifically, when the cap 7 is attached to the extraction tube 4 in a state where the tube portion 16 is screwed to the extraction neck portion 10 by the screw portion 3 and the locking projection 20 is locked to the convex portion 19, The cap 7 covers the outer side of the elastic piece 22, whereby the elastic deformation of the elastic piece 22 is prevented, and the locking portion 5 is held in the locked state in which the separation is prevented. In the process in which the cap 7 is lifted and removed by the guide means 6, the cap 7 still covers the elastic piece 22 at the initial stage of lifting, and the locking of the extraction cylinder 4 and the container body 1 by the locking portion 5. The state is maintained, and only the cap 7 can be lifted from the extraction cylinder 4. When the cap 7 is considerably lifted, the cap 7 reaches above the elastic piece 22, and the elastic piece 22 can be elastically deformed, and the locking portion 5 that locks the container body 1 and the extraction tube 4 is It is supposed to be able to leave.

The operation of the liquid material storage container according to this embodiment will be described. The liquid material is extracted from the liquid material storage container in which the extraction cylinder 4 is screwed into the container body 1 and the cap 7 is attached to the extraction cylinder 4. In this case, the cap 7 is twisted with respect to the extraction cylinder 4 via the guide means 6 and removed. At this time, since the cap 7 can hold the locked state of the locking portion 5 at the beginning of twisting, the relative rotation between the extraction tube 4 and the container body 1, that is, the screw, regardless of whether the cap 7 is twisted in the left-right direction. The loosening of the portion 3 can be prevented, and only the cap 7 can be smoothly removed from the extraction cylinder 4 and thus the container body 1 by the detachment operation using the guide means 6.

  Specifically, at the beginning of twisting, the elastic deformation of the elastic piece 22 is prevented by the cap 7, whereby the locking portion 5 is in the locked state and the screw portion 3 does not loosen, and then the cap 7 is equivalent. At this point, the elastic piece 22 is allowed to be elastically deformed and the locking portion 5 is in a detachable state. At this time, however, the cap 7 already has the V-shaped projection 34 in the V-shaped groove 34. At this stage, the threaded portion 3 is not loosened by the rotation operation by the twist, and the mounting state of the extraction cylinder 4 to the container body 1 is maintained. Then, by removing the cap 7, it is possible to extract the liquid material from the extraction port 2 of the extraction cylinder 4 that is attached to the container body 1. After extraction, the extraction port 2 can be sealed by attaching the cap 7 to the extraction cylinder 4 via the guide means 6.

  On the other hand, when storing or replenishing a liquid substance in the container main body 1, the extraction cylinder 4 is rotated in the loosening direction of the screw portion 3 with respect to the container main body 1 with the cap 7 removed. As a result, the locking protrusion 20 is detached from the convex portion 19 with the elastic deformation of the elastic piece 22 to release the locking portion 5, and the extraction cylinder 4 can be removed from the container body 1 via the screw portion 3. Thus, the liquid material can be replenished from the opening 12 of the extraction neck 10. After replenishing the liquid material, the cylindrical portion 16 is screwed to the extraction neck portion 10 by the screw portion 3, and the protruding portion 19 is moved over the locking portion 20 to be locked. Thereafter, the cap 7 is attached to the extraction cylinder 4.

As described above, the liquid storage container according to the present embodiment has the container main body 1 that stores the liquid substance in an extractable manner and the extraction port 2, and the container main body 1 via the screw portion 3. Extraction tube 4 that is screwed so that it can be loosened and loosened, a locking portion 5 that is provided between extraction tube 4 and container body 1 and that can be detachably engaged with each other, and guide means 6 to perform extraction by pushing down operation is disengaged operation and is guided by twisting rotating operation either to the left or to the right relative to the mounting operation and the extraction tube 4 with respect to the cylinder 4, while being detachably attached to the extraction tube 4 so as to seal the spout 2, the locking The cap 5 is held in a state of being attached to the extraction cylinder 4 and is made detachable in the process of being detached from the extraction cylinder 4. In the radial direction to the extraction tube 4 and the convex portion 19 formed to protrude outward in the direction. The elastic piece 22 formed to be elastically deformable is formed so as to project inward in the radial direction of the extraction cylinder 4, and is convex with elastic deformation of the elastic piece 22 by tightening the extraction cylinder 4 into the container body 1. From the locking projection 20 that is released from the convex portion 19 with the elastic deformation of the elastic piece 22 by loosening the extraction cylinder 4 by operating force over the convex portion 19 while overcoming the convex portion 19. Thus, a stopper portion 25 is formed between the container body 1 and the extraction tube 4 to prevent the extraction tube 4 from rattling around the container body 1 after the locking projection 20 is locked to the convex portion 19. Therefore, the locking state between the container main body 1 and the extraction cylinder 4 by the locking portion 5 is held or made releasable by the cap 7 that is attached to and detached from the extraction cylinder 4, and the cap 7 using the guide means 6 is used. Even if the rotation operation is performed in the same direction as the direction of the screw part 3, It is possible to reliably prevent the part 3 from co-rotating, so that both the detachment of the extraction cylinder 4 to the container body 1 and the detachment of the cap 7 to the extraction cylinder 4 can be performed by a rotating operation. Convenient and good operability can be ensured.

  Since the liquid material storage container having such a configuration is a replacement type in which the liquid material is directly replaced, it is possible to save resources as compared with a configuration in which another container such as a refill for replacement is attached to and detached from the container body 1. Is suitable. In addition, when the container body 1 is made of glass and the extraction cylinder 4 is made of a synthetic resin, the extraction cylinder 4 can be easily detached from the container body 1 and can be separated. High adaptability can be demonstrated.
