Detailed ways

Hereinafter, the inner plug 1 and the container 11 of the present invention will be described in detail with reference to the drawings. 1 to 6 are diagrams related to the inner plug 1 of the present invention, and Figs. 7 and 8 are diagrams of a container 11 equipped with the inner plug 1 described above.

The inner plug 1 of the present invention is installed in the mouth of the container in order to eject liquids or fluids such as medicines. As shown in FIGS. top part 2. The inside of the inner plug 1 is hollow, the shape (outer shape) of the tip portion 2 is substantially a truncated cone shape, and the shape of the main body portion 3 is a columnar shape. Although the shapes of the top end portion 2 and the main body portion 3 are roughly truncated conical and cylindrical respectively in the figure, the shapes of the top end portion 2 and the main body portion 3 are not limited thereto. The above-mentioned top end portion 2 can be in the shape of a frustum. The main body part 3 may be a tubular shape with a hollow inside, and the shape is not particularly limited.

The above-mentioned top end portion 2 of the above-mentioned inner plug 1 is formed with a concave portion 5 that becomes wider upward and wider as shown in FIG. Dimpled shape. Although the bottom surface of the above-mentioned concave portion 5 is a curved surface in the figure, its shape is not limited to this. Two grooves 7 are formed on the edge portion 6 on the same straight line passing through the center of the edge portion 6 so as to partition the edge portion 6 . The groove 7 is provided to cause deformation of the distal end 2 such that the upper surface of the distal end 2 bends along the groove 7 when a force is applied to the distal end 2 from above.

The edge portion 6 is divided into two by the two opposing grooves 7 , and the grooves 7 are shaped to pass through the inclined outer peripheral surface of the tip portion 2 to the inside of the concave portion 5 . The shape of the groove 7 partitioning the edge portion 6 (the cross-sectional shape of the groove in FIG. 2 ) can be appropriately set, such as U-shape, V-shape, or a deformed shape thereof, and is not particularly limited.

The lower surface of the tip portion 2 corresponds to the shape of the bottom surface of the concave portion 5 , and a convex portion 8 protruding downward toward the inside of the main body portion 3 is formed. Although the convex portion 8 has a substantially domed shape, it is not particularly limited, and may be changed to a shape that matches or differs from the bottom shape of the concave portion 5 .

A discharge portion composed of at least one slit 9 penetrating from the concave portion 5 to the convex portion 8 is formed on the distal end portion 2 of the inner plug 1 . As shown in Figure 3, the above-mentioned slit 9 whose planar shape is linear is formed on the bottom surface of the concave part 5 (equivalent to the top surface of the convex part 8 located inside the inner plug), and the above-mentioned slit 9 is opened to form a nozzle. The discharge part that discharges liquid etc. As one example, as shown in FIG. 3 , one slit 9 perpendicular to the straight line where the two grooves 7 are located is formed. Although the said slit 9 penetrates the surface of the said recessed part 5 to the surface of the said convex part 8, as shown in FIG.2(b), it is normally a closed state.

In order that the inner plug 1 of the present invention can smoothly carry out the action of the spout part, that is, when the top end 2 is applied with force, it will be deformed, and the liquid, etc. can pass through; when no force is applied, the liquid, etc. It is better to form a deformable material, and the body part 3 and the top part 2 are integrally formed by elastic deformable material. After the main body 3 and the top end 2 are integrally molded by elastically deformable materials, the number of parts of the inner plug can be reduced, and the manufacture is simpler.

As shown in FIG. 1 , a stepped portion 18 is provided on the outer surface of the main body portion 3 of the inner plug 1 , and an upper portion 19 and a lower portion 20 are formed by the stepped portion 18 . Especially when the tip part 2 and the main body part 3 are integrally molded with resin, by making the wall thickness of the upper part 19 thinner than that of the lower part 20, the upper part 19 can more easily deform the tip part 2, and it can be viewed from above. When excessive force is applied to the tip portion 2 , the entire body portion 3 can be prevented from being broken by the lower portion 20 .

In order to easily and accurately install the inner plug 1 on the container as required, there may be an installation part 4 under the main body part 3 . The mounting portion 4 may be formed in the shape of a flange surrounding the lower periphery of the main body portion 3, and the inner plug 1 may be mounted to the container by using the mounting portion 4. A groove 10 is formed on the mounting portion 4 as if surrounding the main body 3 , and the groove 10 is used for fixing the inner plug 1 . The method for attaching the inner plug 1 to the container body will be described in detail later.

Next, the opening and closing operation of the discharge portion of the inner plug 1 will be described. When the inner plug 1 is not subjected to any force, the slit 9 is closed as shown in FIG. 2( b ), and in this state, liquid or the like cannot pass through the slit 9 .

After the top end 2 of the above-mentioned inner plug 1 is exerted from above by pressing the top end 2 to the affected part, etc., since the above-mentioned inner plug 1 is formed of an elastically deformable material, the stressed top end 2 is deformed. A force applied from above to the tip portion 2 acts on the edge portion 6 . Next, as shown in FIG. 5 (a), the two grooves 7 formed on the above-mentioned edge portion 6 function as a fold line, whereby the top of the tip portion 2 faces toward the area divided by the groove 7 of the above-mentioned edge portion 6. The two parts are deformed in the direction of approaching each other. As a result, the above-mentioned tip 2 is deformed into a shape like a depression in the middle of the upper surface.

After such deformation occurs in the tip portion 2, as shown in FIG. 5(a) to FIG. deformed. After the surface of the above-mentioned convex portion 8 is deformed like expanding downward, the above-mentioned slit 9 is stretched left and right on the side of the above-mentioned convex portion 8, and is gradually deformed in the direction of opening, as shown in (b) of FIG. As shown, the above-mentioned slit 9 is deformed into a substantially inverted V-shaped cross-section opened downward.

In the deformed state of the slit 9, liquid or the like can pass through the slit 9 from the side of the main body 3, and the slit 9 functions as a discharge portion. When the force applied to the distal end portion 2 from above is stopped, the deformation of the convex portion 8 returns to its original shape, and the slit 9 is closed again. Therefore, the discharge portion is closed and liquid cannot pass through. The above-mentioned slit 9 functions as an opening and closing valve by such deformation, and opens and closes the discharge part.

The above-mentioned deformation of the inner plug 1 preferably utilizes the properties of elastically deformable materials. The elastically deformable material includes artificial rubber, silicone, etc., and from the viewpoint of the above-mentioned opening and closing of the slit 9, it is preferable to use artificial rubber, silicone, and most preferably silicone.

The inner plug 1 of the present invention has the following characteristics due to the use of these materials: deformation occurs by a certain amount before a certain amount of deformation; During the actual operation, the force applied to the inner plug 1 is the action of pressing the top end portion 2 to the affected area, so the change in the amount of deformation of the top end portion 2 at a certain point of time will be obvious to the user. Therefore, it can give the user a sense of touch (when the top end of the inner plug is pressed to the affected area, the top end is concave and deformed, thereby making the user feel that the affected area has been massaged), and the better effect brought by the top end 2 Effective massaging sensation. In this way, the inner plug 1 can effectively massage the affected part while ejecting liquid or the like.

Although the above-mentioned inner plug 1 becomes a state where the slit 9 is deformed and the discharge part is opened after the above-mentioned tip part 2 is biased from above, the slit 9 is normally closed, so that the constituent liquid etc. cannot flow A structure in which the ejection part ejects outward.

The structure for ensuring the airtightness in the closed state of the slit 9 will be described below. In the inside of the inner plug 1, when the liquid in the container acts on the discharge part (this state occurs when the container is turned upside down, etc.), as shown by the arrow in (c) of Fig. 5, the liquid in the container Force is applied to the surface of the convex portion 8 inside the tip portion 2 .

When the force in the direction of the arrow acts on the surface of the convex portion 8, the convex portion 8 is deformed in a direction in which the protrusion amount decreases because the convex portion 8 has a dome shape projecting downward. Due to the deformation of the convex portion 8, the slit 9 is deformed in a tighter and closed direction, so that the degree of airtightness of the discharge portion is increased, preventing the discharge of liquid or the like. Therefore, it is possible to prevent the container from tipping over, or when the container is turned down without pressing the tip to the affected area, etc., and the liquid is accidentally ejected from the discharge part, and large droplets during use can also be prevented.

The discharge rate of the discharge unit using the above-mentioned slits 9 varies depending on the installation state and number of the slits 9 . Figure 6 shows slits 9 of three shapes. The direction of the slit 9 shown in (a) of FIG. 6 is different from FIG. 3 . In FIG. 3 , slits 9 are formed in a direction perpendicular to the two grooves 7 , but in FIG. 6( a ), one slit 9 is formed on the same straight line as the two grooves 7 .

The shape shown in (b) of FIG. 6 is a shape in which two slits 9 are formed perpendicular to each other, and is a shape in which the slits 9 shown in FIG. 3 and (a) of FIG. 6 are combined. (c) of FIG. 6 shows a shape in which three slits 9 are formed. So far, four kinds of shapes of slits 9 have been shown, and the discharge volume of the discharge part formed by these slits 9 is as shown in Fig. 6(a), Fig. 3, Fig. 6(b), Fig. 6(c) The order of increasing, therefore, the shape of the slit 9 can be appropriately selected according to the required discharge amount. The shape of the slit 9 described here is just one example, and other configuration states and numbers can also be adopted.

Next, the container 11 of the present invention will be described. The container 11 of the present invention is a container in which the above-mentioned inner plug 1 is attached to the container body 14, and the liquid or the like in the above-mentioned container body 14 can be ejected by the above-mentioned inner plug 1 . As shown in FIGS. 7 and 8 , the inner plug 1 is mounted on the container main body 14 with a fixture 12 on the mouth 13 fitted on the container main body 14 , and the container 11 also has a cap 15 .

The fixture 12 has cylindrical side surfaces and an upper surface with an opening in the middle. And, on the inner peripheral surface of the above-mentioned side surface of the above-mentioned fixing tool 12, a joint portion that is engaged with the outer peripheral surface of the mouth portion 13 provided on the container main body 14 is formed, and the periphery of the opening of the above-mentioned upper surface serves as a function for pressing the inner surface from above. The components of the mounting portion 4 of the plug 1 function. Moreover, an annular protrusion 17 protruding downward is formed on the lower surface around the opening, and the protrusion 17 is inserted into the groove 10 of the mounting portion 4 of the inner plug 1 .

Next, a method of fixing the inner plug 1 using the aforementioned fixing tool 12 will be described. The inner plug 1 is placed on the top of the mouth 13 , and the fixture 12 is engaged with the mouth 13 from above the inner plug 1 . At this time, the above-mentioned fixing device 12 presses the installation part 4 of the above-mentioned inner plug 1 from above, and at the same time, the protrusion 17 of the above-mentioned fixing device 12 is inserted into the groove 10 of the above-mentioned installation part 4 from above, so the above-mentioned inner plug 1 is fixed by the above-mentioned The appliance 12 is fixed. At this time, the top end portion 2 of the inner plug 1 is in a state of protruding upward from the opening of the fixture 12 . In this way, after the inner plug 1 is fixed on the container body 14 by the fixing device 12, the inner plug 1 can eject the liquid in the container body 14 from the container 11. Regarding the installation method of the above-mentioned inner plug 1, other methods may also be adopted, for example, the above-mentioned inner plug 1 may be directly embedded into the container main body 14 and fixed without using a fixing device. For the fixture, other configurations are also possible.

The container 11 uses a cap 15, on the inner surface of the cap 15 is formed a substantially dome-shaped first projection 16 protruding downward to be inserted into the recess 5 of the tip end 2 of the inner plug 1. When the cap 15 is closed, the first protrusion 16 is inserted into the recess 5 as shown in FIG. 8 and is tightly attached to the surface of the recess 5, whereby the effect of closing the discharge portion of the inner plug 1 is produced. With the cap 15 having such a structure, the airtight state of the discharge portion of the inner plug 1 can be further improved, and the leakage of the liquid in the container 1 can be reliably prevented.

The container 11 of the present invention equipped with the above-mentioned inner plug 1 improves airtightness through the inner plug 1 having a simpler structure than before, and also has a massage function utilizing the inner plug 1 while ejecting liquids and the like. For example, when it is used as a medicine such as a hair growth agent, the front end 2 of the inner plug 1 is pressed against the scalp, and the medicine can be sprayed out while the front end 2 can be effectively massaged. In addition, it can also be used as a container for medicines, cosmetics, etc. that need to be massaged while spraying a liquid or the like on an affected part, and can also be used for various other uses.

Regarding the inner plug 1, the case where two grooves 7 are provided on the same straight line has been described, but one groove 7 may also be used. For example, FIG. 9 shows the inner plug 1' when the inner plug 1 shown in FIG. 1 has one groove 7. Even in this shape, the upper surface of the tip part 2 can be bent with the above-mentioned groove 7 as a folding line. Deformation of top 2 above.

Inner plugs 21 of other shapes will be described below. As shown in FIGS. 10 to 14 , the inner plug 21 has a body portion 23 and a tip portion 22 provided on the top of the body portion 23 with a discharge portion. The inside of the inner plug 21 is hollow, the shape (outer shape) of the tip portion 22 is substantially a truncated cone shape, and the shape of the main body portion 23 is a columnar shape.

The above-mentioned top end portion 22 of the above-mentioned inner plug 21 is formed with a concave portion 25 as shown in FIGS. . On the above-mentioned edge portion 26, as shown in FIG. 12, four grooves 27 are formed on two straight lines perpendicularly intersecting the center of the above-mentioned edge portion 26 as if the above-mentioned edge portion 26 is partitioned. The above-mentioned grooves 27 are provided on the above-mentioned edge portion 26 at the same intervals.

The lower surface of the tip portion 22 corresponds to the shape of the bottom surface of the concave portion 25 , and a convex portion 28 protruding downward toward the inside of the main body portion 23 is formed. Furthermore, as shown in FIG. 12 , two slits 29 penetrating from the concave portion 25 to the convex portion 28 are provided vertically in the distal end portion 22 to form a discharge portion.

When force is applied to the top end 22 of the inner plug 21 from above, the four grooves 27 formed on the edge portion 26 function as folding lines, whereby the top of the top end 22 is moved toward the edge portion 26 by the grooves. 27 The four divided parts are deformed in the direction of approaching each other. As a result, as shown in FIG. 14 , the above-mentioned tip portion 22 is deformed into a shape like a depression in the middle of the upper surface. The inner plug 21 is more easily deformed by providing four grooves 27 and making the width of the grooves 27 wider.

After the tip portion 22 is deformed, the dome-shaped convex portion 28 inside the tip portion 22 is deformed as if protruding inwardly and downwardly from the tip portion 22, and the slit 29 is stretched left and right on the convex portion 28 side. Simultaneously, the convex portion 28 is gradually deformed in the direction of opening, and the liquid or the like can pass through the slit 29, and the slit 29 functions as a discharge portion. When the force applied to the tip portion 22 from above is removed, the deformation of the convex portion 28 returns to its original shape, and the slit 29 is closed again. Therefore, the discharge portion is in a closed state, and liquid and the like cannot pass through. The above-mentioned slit 29 functions as an opening and closing valve by such deformation, and opens and closes the discharge part.

As shown in FIG. 12 , the two slits 29 are provided on two straight lines perpendicular to each other formed by the four grooves 27 . Although the said slit 29 penetrates the surface of the said recessed part 25 to the surface of the said convex part 28, it is normally a closed state.

As shown in FIG. 10 , a stepped portion 38 is provided on the outer surface of the main body portion 23 of the inner plug 21 , and an upper portion 39 and a lower portion 40 are formed by the stepped portion 38 . In addition, a vertical slit 31 is provided on the upper portion 39 of the outer surface of the main body portion 23 . As shown in FIG. 10, the above-mentioned slit 31 is closed in the state where no force is applied to the above-mentioned tip portion 22. After the above-mentioned tip portion 22 is biased, as shown in FIG. During deformation, the slit 31 is opened to open the inside and outside of the main body 23 .

Through the opening and closing of the above-mentioned slit 31, the above-mentioned inner plug 21 opens the inside and outside of the above-mentioned main body part 23, thereby eliminating the pressure difference between the inside and outside of the above-mentioned main part 23 generated when the liquid is ejected from the discharge part, so that the liquid is sprayed. Therefore, the discharge amount is stable, and, in addition to the deformation of the tip portion 22, the above-mentioned main body portion 23 also becomes easier to deform, the deformation of the above-mentioned inner plug 21 occurs more smoothly, and the opening and closing of the discharge portion is smoothly realized. .

As shown in FIG. 13 , the slit 31 is provided on the tip end 22 below one of the four grooves 27 , thereby facilitating opening and closing due to deformation of the upper groove 27 . However, the position of the slit 31 is not limited thereto, and may be changed to another position if it is the outer surface of the main body portion 23, and the number thereof is not limited to one, but may be plural. Moreover, although it is described that the above-mentioned slit 31 is provided vertically, the vertical direction is not limited to the vertical, but also includes an inclined state other than the horizontal direction, and may be inclined within a range of 45° left and right relative to the vertical.

As shown in FIG. 10 , the inner plug 21 has an attachment portion 24 under the main body portion 23 for attachment to a container. The mounting portion 24 is formed in a flange shape surrounding the lower periphery of the main body portion 23 . A groove 30 is formed on the mounting portion 24 as if surrounding the main body portion 23 , and the groove 30 is used for fixing the inner plug 21 .

When the inner plug 21 is biased from above on the distal end portion 22, the slit 29 is deformed and the discharge portion is opened, and at the same time, the slit 31 is deformed and opened. However, since the slit 29 and the slit 31 are closed in a normal state, the liquid etc. are not ejected from the discharge part and the slit 31 to the outside.

Next, the container 41 using the inner plug 21 described above will be described. As shown in FIGS. 15 and 16, the container 41 is a container in which the inner plug 21 is attached to the container body 44, and the liquid in the container body 44 can be ejected by the inner plug 21. As shown in FIGS. 15 and 16 , the inner plug 21 is mounted on the container main body 44 with a fixture 42 on the mouth 43 fitted on the container main body 44 , and the container 41 also has a cap 45 .
