Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a powder container, more specifically, a powder, for example, a cement powder used by a dental clinic, or a powder powder having a particularly fine texture such as a powdered medicine used by an internal medicine department or a surgical clinic. It concerns a powder container used for placing.

[0002]

[Prior art and its problems]

 Generally, the lid that covers the opening (powder outlet) of this kind of powder container has only the so-called cap function, which is the purpose of sealing the opening so that powder in the container does not spill or damp. In addition, when the lid is removed and the container opening is opened, it remains on the inner surface of the lid, especially on the upper surface of the lid that abuts the rim of the container opening. However, each time it is opened, it not only causes it to be scattered on the desk or the floor, but also has a disadvantage that it is wasted. Also, the powder attached to the inner surface of the lid is locked between the lid and the opening of the container by a screw action, so that the powder is stuck between the two threaded portions, and the lid is tightly covered on the opening of the container. Has a number of inconveniences and drawbacks, such as that it becomes impossible to remove the lid, or the powder clogged between the screw parts when removing the lid slows the rotation of the lid, and as a result it becomes impossible to remove the lid. However, measures and improvements have been desired.

Incidentally, the cause of the powder in the container adhering to the inner surface of the lid body is that the powder in the container is stored by its own weight during storage, and therefore, when the container is shaken during use for the purpose of loosening it. It is thought that the fine powdery powder will naturally adhere, or if the lid is made of plastic, it will be adsorbed and adhered due to the electrostatic action peculiar to plastic.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the conventional inconveniences and drawbacks as described above, and the operation of removing the lid from the opening of the container body allows the powder in the container adhering to be dropped into the container and returned. It is intended to provide an improved powder container.

[0005]

[Means for achieving the object]

 To achieve the above object, the technical means taken by the present invention is to attach a stretchable diaphragm to the mouth of the lid which is detachably attached to the opening of the container body and is stretched. Characterize. In addition, a stretchable diaphragm is attached to the mouth of the lid that is detachably attached to the opening of the container body in a stretched manner, and the inner upper surface of the lid does not hit the diaphragm. It is characterized by the provision of a diaphragm extension protrusion that hangs at a height. Further, a stretchable septum is attached to the mouth of the lid, which is removably attached to the opening of the container body by rotation, and the inner upper surface of the lid is struck against the septum. It is characterized in that a diaphragm-extending protrusion that hangs at a height that does not exist is provided, and that an appropriate number of protrusions for vibration generation are provided on the inner peripheral surface of the mouth of the container body.

[0006]

[Work]

 Thus, according to the above-mentioned technical means according to claim 1 of the present invention, when the lid is capped on the opening of the container body and covered with the opening, the diaphragm attached to the mouth of the lid. Is caught on the edge of the container opening, and is gradually extended as the lid is completely covered by the container opening.In the extended state, the lid and the container are opened together. Cover up. As a result, the diaphragm prevents the powder in the container from coming into contact with the inner surface of the lid and prevents the powder from adhering to the inner surface of the container, and when the lid is removed from the opening of the container body during use, the diaphragm is closed. As the body moves away from the opening in the container body, it gradually shrinks, causing the powder to fall into the container.

Further, according to the technical means as claimed in claim 2, when the lid is capped on the opening of the container body and is covered with the opening, the diaphragm attached to the mouth of the lid is the container. When the lid is hooked on the rim of the opening, the lid gradually expands as the container is completely covered with the opening of the container. Cover the opening of the container together with the lid in a state that it is further extended so as to be pushed into. As a result, the diaphragm prevents the powder in the container from contacting the inner surface of the lid and prevents the powder from adhering to the inner surface of the container.When the lid is removed from the opening of the container body during use, the diaphragm is removed. It gradually shrinks as it moves away from the opening of the container body, i.e., the diaphragm gradually moves away from the opening of the container body from the part that is pushed into the inside of the container by the projection for extending the diaphragm. At the same time as shrinking, finally the part that extends while being caught on the rim of the container opening shrinks, and the powder is dropped into the container by the shrinking action.

Further, according to the technical means as claimed in claim 3, when the lid is capped on the opening of the container main body by rotation and covered with the opening, the diaphragm attached to the mouth of the lid is When the lid is caught on the edge of the container opening, the lid is gradually extended as it is completely covered by the container opening, and the protrusion for diaphragm extension hits the inside of the container by the protrusion. Cover the opening of the container together with the lid in a state where it is further extended so as to be pushed inward. As a result, the diaphragm prevents the powder in the container from contacting the inner surface of the lid and prevents the powder from adhering to the inner surface, and when the lid is rotated during use, it is removed from the opening of the container body. The diaphragm gradually shrinks as the lid moves away from the opening of the container body, and it also shrinks while being vibrated by the vibration generating projections protruding from the mouth of the container opening, that is, the diaphragm is for stretching the diaphragm. While the lid gradually shrinks from the portion pushed into the inside of the container by the protrusion as it moves away from the opening of the container body, at the same time vibration is applied by the vibration generating convex portion and finally the container opening The part that expands while being caught on the rim shrinks, and the shrinking action causes the powder to fall into the container.

 1 to 6 show an embodiment according to claim 1, wherein 1 is a container body, 2 is a lid, 3 is a diaphragm, and 1 is a container body. Is a bottle formed into an appropriate shape and size capable of accommodating powder, for example, cement powder used by a dental clinic, or a powdered powder 4 having a particularly fine texture such as a powdered drug used by an internal medicine or a surgical clinic. On the outer peripheral surface of the upper opening 1a, which is narrowed down from the body part by about one turn, a male screw 5 that locks the lid body 2 with a screw action and is crowned is formed on the lower half side, that is, the body part as shown in the figure. It is provided near the root. In addition, it is preferable to mold the container body 1 using a transparent member such as plastic or glass so that the remaining amount (capacity) of the contained powder 4 can be confirmed from the outside.

The lid body 2 has an opening and a diameter such that a clearance can be secured between the lid body 2 and the upper half of the outer peripheral surface of the opening 1a of the container body 1 so that the diaphragm 3 can be loosely fitted therein. A body portion 2a formed into a size that can cover the portion 1a substantially completely, and a female screw 6 on the inner peripheral surface which is fitted into the mouth of the body portion 2a and integrally attached by fixing means such as adhesion. The mouth ring 2b having the above-mentioned structure is used, and the elastic diaphragm 3 is attached to the mouth portion of the lid 2 in a stretched manner by the mouth ring 2b. The main body portion 2a is provided with stepped portions 7 and 8 in which the apertures are continuously expanded and expanded in a multi-step manner toward the rim at an appropriate depth on the inner peripheral surface of the lips on the outer peripheral surface of the throat ring 2b. Is provided with stepped portions 9 and 10 which are continuously provided in a shape that can be fitted and fitted into the stepped portions 7 and 8, and a female screw 6 is engraved on the inner peripheral surface thereof.

Reference numeral 11 in the figure denotes a stop ring for fixing the peripheral edge of the diaphragm 3 to the step portion 9 of the mouth ring 2b, and this stop ring 11 has the same width as the height of the step portion 9 and The diaphragm 3 is formed to have a ring diameter such that it can be attached to the diaphragm 3, and the inner peripheral surface of the diaphragm 3 is fitted and locked to the recess 12 formed on the outer peripheral surface of the stepped portion 9. 3 A ridge 13 is formed to prevent the peripheral edge from coming off. Reference numerals 14 and 15 are projections and recesses of appropriate shapes, which are provided on the step portion 7 of the lid 2 main body portion 2a and the step portion 9 of the mouth ring 2b so as to correspond to several portions in the circumferential direction. By fitting and locking with the concave portion 15, the main body portion 2a and the mouth ring 2b are integrated in the rotational direction when the lid body 2 is attached to or detached from the opening portion 1a of the container main body 1, whereby the main body is formed. The mouth ring 2b provided with the female screw 6 is prevented from idling when the lid 2 is attached and detached by gripping the portion 2a (see FIG. 6).

The diaphragm 3 is formed into a sheet having an appropriate thickness by using a desired elastic member having elasticity such as latex rubber or silicon rubber, and its peripheral edge is formed on the step portion 9 on the outer peripheral surface of the mouth ring 2b. After covering the mouth ring 2b so that it fits, fit the stop ring 11 and attach it to the mouth ring 2b with some tension (tensioned), and then attach the mouth ring 2b to the lid 2 main body. It is mounted in the lid body 2 as shown in the figure by being fitted and integrally mounted on the mouth step portions 7 and 8 of the portion 2a.

Thus, according to the powder container of claim 1 configured as described above, when the lid 2 is rotated to cover the opening 1a of the container body 1 and cover the opening 1a, the lid is closed. The diaphragm 3 attached to the mouth of the body 2 is caught in the opening 16a of the opening 1a of the container body 1 and gradually expanded as the lid 2 is completely covered with the opening 1a. In the expanded state, the lid 2 and the opening 1a of the container are covered and closed together (see FIG. 2). Thereby, the diaphragm 3 prevents the powder 4 in the container from coming into contact with the inner surface of the lid 2 and prevents the powder from adhering to the inner surface, and at the time of use, the lid 2 is rotated to remove it from the opening 1a of the container body 1. Then, the diaphragm 3 gradually shrinks as the lid 2 moves away from the opening 1a of the container main body 1, and the powders 4 adhered by the shrinking action close to each other, thereby colliding with each other. While dropping it back into the container body 1 (see FIG. 5).

FIGS. 7 to 8 show an embodiment according to claim 2, and the container main body 1, the lid 2 and the method of attaching the diaphragm 3 to the mouth of the lid 2 are described in detail in the embodiment of claim 1. Since it is basically the same as the one described above, the same reference numerals are used for the same components and the description of the components will be omitted. In the case of the second aspect, as described in detail in the first aspect of the first aspect, a configuration is provided in which a protrusion 17 for extending the diaphragm is provided on the inner upper surface of the lid 2 with a length that does not abut the diaphragm 3. It is a thing.

When attaching the lid body 2 to the opening 1a of the container body 1, the diaphragm extension protrusion 17 is completely covered with the opening 1a of the lid 2 while being hooked on the rim 16 of the opening 1a. The powder 4 which adheres by increasing the contraction rate of the diaphragm 3 generated when the lid 2 is removed by pushing the diaphragm 3 which is gradually expanded as it further extends into the container so as to further expand. 1 It has a function of dropping more effectively than the configuration described in detail, and it is hung from the center of the upper surface of the main body 2a of the lid 2 with a length (height) that does not hit the diaphragm 3. At the same time as the diaphragm 3 is caught by the opening edge 16a of the container body 1 and extended, or at the same time, it is slightly extended and then the lower end (protruding end) is abutted to push the diaphragm 3 inward of the container to extend Is. The projection shape and the number of the projections 17 for extending the diaphragm are not limited to those in the illustrated example, and it is of course possible to provide projections of an appropriate projection shape at several places.

Thus, according to the powder container of claim 2, when the lid 2 is rotated to cover the opening 1a of the container body 1 and cover the opening 1a, the lid 2 is opened. The attached diaphragm 3 is hooked on the opening edge 16a of the container body 1 and gradually extended as the lid body 2 is completely covered with the opening 1a. When the protrusion 17 hits, the protrusion 17 further extends so that the protrusion 17 is pushed into the inside of the container and covers the opening 2a of the container body 1 together with the lid body 2 (see FIG. 8). When the lid 2 is rotated to remove it from the opening 1a of the container body 1 during use, the diaphragm 3 gradually shrinks as the lid 2 moves away from the opening 1a of the container body 1, that is, The diaphragm 3 gradually shrinks as the lid 2 moves away from the opening 1a of the container body 1 from the portion pushed into the inside of the container by the projection 17 for diaphragm extension, and finally the opening of the container body 1 1a The part that expands when it is caught in the rim 16 shrinks, and the powders 4 that adhere due to the shrinking action close the mutual distances, so that they collide with each other and effectively fall into the container body 1. Will be returned to the best.

9 to 11 show an embodiment according to claim 3, and the method of attaching the diaphragm 3 to the mouth of the container body 1, the lid body 2 and the lid body 2 is as described above. Since this is basically the same as the detailed description, the same reference numerals are used for the same components, and the description of the components will be omitted. According to the third aspect of the present invention, the container body 1 described in detail in the first aspect has a configuration in which an appropriate number of vibration generating projections 18 are provided on the inner peripheral surface of the mouth.

The vibration generating projections 18 prevent the lid 2 from rotating when the lid 2 is rotated and removed from the opening 1a of the container body 1 by the diaphragm 3 extending by the diaphragm extension projections 17. It acts to drop the powder 4 adhered by vibrating with, more effectively than the structure described in detail in claim 2, and as shown in the figure, an appropriate number of the powder 4 can be provided on the inner peripheral surface of the mouth of the container body 1. In the example shown in the figure, three inner circumferences are provided so as to project inward at predetermined intervals.

FIG. 12 shows another example of a projecting configuration of the vibration generating convex portion 18 with respect to the opening 1a of the container body 1. In this embodiment, a synthetic resin is formed separately from the container body 1. The rim body 19 integrally provided with the convex portion 18 formed with the diameter of the opening 1a of the container body 1 is fixedly fitted into the opening 1a in a non-rotatable manner so that the opening 1a The vibration generating convex portion 18 is provided on the inner peripheral surface of the mouth.

Thus, according to the powder container of claim 3, when the lid 2 is rotated to cover the opening 1a of the container main body 1 and the opening 2 is covered with the lid 2, The diaphragm 3 attached to the mouth of the container 2 is in a state of being caught by the opening edge 16 of the opening 1a of the container body 1 and is gradually extended as the lid 2 is completely covered with the opening 1a. When the protrusion 17 for extending the diaphragm is struck, the protrusion 17 further pushes it toward the inside of the container to further extend it, and covers the opening 2a of the container body 1 together with the lid body 2 (see FIG. 10). ). When the lid 2 is rotated to remove it from the opening 1a of the container body 1 during use, the diaphragm 3 gradually shrinks as the lid 2 moves away from the opening 1a of the container body 1 and the container 3 Vibration is generated by the vibration generating projections 18 projecting from the opening 1a of the main body 1 so that the diaphragm 3 is contracted, that is, the diaphragm 3 is pushed from the inside of the container by the diaphragm extending projections 17 to the lid. 2 gradually shrinks as it moves away from the opening 1a of the container body 1, and at the same time, vibration is applied by the vibration-generating convex portion 17 and finally extends while being caught by the rim 16 of the opening 1a of the container body 1. The powder 4 attached due to the synergistic effect of both the contraction of both of them and the vibration that causes the contracted portion is more effectively dropped into the container body 1 and returned.

[Effect of device]

 Since the powder container of the present invention is constructed as above, it has the following operational effects. ． According to the powder container of claim 1, when the lid is removed from the opening of the container body during use, the lid is caught by the opening edge of the container body and the lid is opened. The membrane that covers the container opening along with the lid in the expanded state is gradually extended as the lid is separated from the opening of the container body. The powder can be dropped back into the container by the shrinking action. ． According to the powder container of claim 2, when the lid is removed from the opening of the container body during use, the lid is caught by the opening edge of the container body and the lid is opened. When the diaphragm extension projection is struck by the projection, the diaphragm extension projection is pushed into the inside of the container by the projection, and is further extended. The septum that covers the opening gradually shrinks as the lid moves away from the opening of the container body, that is, the septum is pushed from the inside of the container by the protrusion for diaphragm extension to the lid of the container body. The powder gradually drops as it moves away from the opening of the container, and finally the part that extends while being caught by the rim of the container opening contracts. It shimete return it can be. ． According to the powder container of claim 3, when the lid is turned to remove it from the opening of the container body during use, the container is hooked on the edge of the container opening and the lid opens. The container is gradually extended as it is completely covered, and when the projection for diaphragm extension hits the container, it is further expanded so that it is pushed inward by the projection and the container together with the lid. The diaphragm that covers the opening of the container gradually shrinks as the lid moves away from the opening of the container body, and at the same time, it shrinks while being vibrated by the vibration-generating projections protruding from the mouth of the container opening. The diaphragm gradually contracts as the lid moves away from the opening of the container body from the part that is pushed inward by the protrusion for diaphragm expansion, and at the same time it vibrates due to the convex part for vibration generation. When the powder is added, the part that expands in the state of being caught on the rim of the container opening part is contracted, and the synergistic effect of both of the contraction and vibration causes the powder to enter the container more effectively and reliably. It can be dropped and returned.

Therefore, according to the powder container of the present invention, by removing the lid from the opening of the container main body, the powder in the container attached can be dropped and returned in the container. No powder adheres to the inner surface of the lid when it is removed from the opening of the container body. As a result, the powder container is a container in which all the inconveniences and drawbacks of the conventional container, such as the powder spilling on the desk and being wasted as in the conventional case, can be eliminated.
