1 is an exploded perspective view of an embodiment of a toothpaste and fluid dispenser according to the present invention, Figure 2 is a combined perspective view of the embodiment of Figure 1, Figure 3 is a longitudinal cross-sectional view in the combined state of FIG.

The first housing 110 is a cylindrical shape in which a hollow is formed, but is illustrated as cylindrical in FIGS. 1 to 3, but it is not necessarily cylindrical. The cross-sectional shape may be a polygon or other shape such as a triangle or a square.

The adapter 120 also has a hollow cylindrical shape and is installed to be inserted into the hollow of the first housing 110. The adapter 120 accommodates an outlet provided to allow the fluid to flow out of a separate storage container in which the fluid is filled, such as a commercially available tubular toothpaste container. For example, the toothpaste outlet of the tubular toothpaste container is inserted into the upper end of the adapter 120 based on the drawing direction of FIG. 3. Hereinafter, the direction division of the upper and lower sides is based on the drawing direction of FIG. 3. Adapter 120 is also preferably made of a flexible material in close contact with the outer periphery of such an outlet to maintain airtightness. For example, a material such as soft silicon may be used as the material of the adapter 120. The surface where the adapter 120 is in contact with the first housing 110 is divided into three parts, such as a large diameter part 122, a small diameter part 123, and an adhesion part 124. The large diameter portion 122 is a portion of the outer circumferential surface of the adapter 120 portion inserted into the hollow of the first housing 110 is a relatively large portion, it is illustrated in the form of a thread in Figs. It does not need to be a shape, and if it is a shape which can contact the hollow inner peripheral surface of the 1st housing 110, it is sufficient. The small diameter portion 123 is a portion having a smaller outer diameter than the large diameter portion 122 and forms an empty space between the small diameter portion 123 and the inner circumferential surface of the first housing 110. The empty space thus formed is positioned above the space formed by the connection tube 150 in use. For example, when used as a toothpaste dispenser, in the tubular toothpaste container, not only toothpaste but also air is dispersed in the toothpaste in the form of bubbles. Alternatively, when the toothpaste is not used while remaining in the connection tube 150, the toothpaste is sedimented by gravity and bubbles are released to the outside of the toothpaste, forming a group of air masses that are separate from the toothpaste and the connection tube 150. It takes up a certain amount of volume within. At this time, if the volume is reduced by compressing the connection tube 150, the possibility of air passing through the first check valve 121 in the reverse direction to enter the toothpaste container. If air enters the toothpaste container, the toothpaste may not be smoothly discharged even when the connection tube 150 is compressed and returned to its original state. The empty space formed by the small diameter portion 123 temporarily accommodates such air masses so that the toothpaste can be smoothly discharged. The remaining close contact portion 124 is a part in close contact with each other to maintain airtightness between the outer circumferential surface of the adapter 120 and the inner circumferential surface of the first housing 110.

The first check valve 121 allows the fluid including the toothpaste to pass only in one direction in the hollow of the first housing 110. The direction through which the toothpaste and fluid pass is from top to bottom. The first check valve 121 may be formed as a separate member and installed in the first housing 110, but as shown in FIGS. 1 to 3, the first check valve 121 may be integrally formed at one end of the adapter 120 to provide a simpler structure. It can also be prepared. Specifically, the first check valve 121 is a valve (121a) formed to close the lower end of the adapter 120, the opposite end of the end in which the outlet of the fluid storage container is inserted in the adapter 120 and the valve 121a It may be composed of a slit 121b made by cutting. In particular, when the first check valve 121 is formed by the plate 121a integrally formed with the adapter 120 of the flexible material, the slit 121b is in close contact when the external force does not work due to the characteristics of the material. The state is maintained, but when an external force is applied, the slit 121b is opened to form a passage of the fluid. In addition, by adjusting the width of the slit 121b according to the thickness direction of the valve 121a, it is possible to induce the fluid to pass in only one direction. For example, as illustrated in FIG. 3, when the slit 121b is formed such that its width becomes wider at the upper end and narrower at the lower end, the fluid allows movement from the upper side to the lower side of the valve 121a but prevents it from moving in the opposite direction. Effect is obtained. This is because when the fluid tries to move upward from the bottom of the valve 121a, the slit 121b is further blocked as the valve 121a is deformed. On the contrary, when the fluid tries to move from the upper side to the lower side of the valve 121a, even if the valve 121a is deformed, the width of the slit 121b is wide so that a passage of a constant width is allowed without being completely blocked.

The second housing 130 has a hollow cylindrical shape like the first housing 110 and is spaced apart from the first housing 110. In this case, the center line of the second housing 130 and the center line of the first housing 110 may be positioned on a straight line.

A second check valve 141 is installed in the second housing 130 to control a moving direction of the fluid. The second check valve 141 may also be made in various forms, but the valve 141a and the valve as a flexible material that can close the hollow of the second housing 130 like the first check valve 121 described above. It is preferable to be embodied in the form of the slit 141b formed in 141a. However, unlike the first check valve 121, it can not be manufactured integrally with other components such as the adapter 120, it is made of a single member is installed in the hollow of the second housing 130. The shape of the second check valve 141 may have the same shape as that of separately manufacturing the lower end of the adapter 120 in the adapter 120 in which the first check valve 121 is integrated.

The connection tube 150 is disposed between the first housing 110 and the second housing 130 spaced apart from each other, and is made of a material having both flexibility and elasticity, and both ends of the connection tube 150 are respectively disposed in the first housing ( It is fixed to the bottom of the 110 and the top of the second housing 130. 1 to 3, the connection tube 150 is illustrated as having a cylindrical shape with a circular cross section, but is not necessarily limited to this shape and may have other cross-sectional shapes, such as polygonal or elliptical. In fixing the connection tube 150, fixing rings 160 and 170 may be provided to stably maintain the fixing between the members to prevent the connection tube 150 from being separated. As illustrated in FIGS. 1 to 3, when the connection tube 150 is coupled to the outer circumference of the first housing 110 or the second housing 130, the fixing rings 160 and 170 are disposed outside the connection tube 150. At the peripheral side, the connection tube 150 is pressed against the first housing 110 and the second housing 130. On the contrary, the connection tube 150 may be coupled to the inner circumference of the first housing 110 or the second housing 130. In this case, the fixing rings 160 and 170 may be connected to the inner circumference of the connection tube 150. ) Is pressed into the first housing 110 and the second housing 130. The retaining rings 160 and 170 may be formed of metal or plastic rings, and may be replaced by a binding band commonly known as a cable tie. In addition, other fixing methods may be used, such as the fixing rings 160 and 170 may be omitted, and the connection tube 150 may be adhered to the first housing 110 or the second housing 130 with an adhesive or melt-bonded.

When fixing the connection tube 150 with the fixing rings (160, 170), to form a protruding flange (110a, 130a) on the lower end of the first housing 110 and the upper end of the second housing 130, respectively for a more secure fixing It is preferable. Each of the protruding flanges 110a and 130a may further suppress the connection tube 150 from being separated into each of the first housing 110 and the second housing 130 by partially expanding both ends of the connection tube 150. .

In this state, the toothpaste outlet of the storage container filled with a fluid, such as a tubular toothpaste container, is inserted into the hollow of the adapter 120 from the top of the adapter 120. Since the inner diameter of the adapter 120 is adapted to the size of the toothpaste outlet, the outer periphery of the toothpaste outlet and the inner periphery of the adapter 120 may be in close contact with each other to maintain airtightness to the outside. At this time, when an external force is applied to reduce the internal volume of the connection tube 150, the air inside the connection tube 150 is increased while being discharged to the outside, the first check valve 121 is upward It is not discharged and is discharged downward through the second check valve 141. When the external force on the connection tube 150 is removed, the internal volume increases as the connection tube 150 is restored to its original state by the restoring force of the elastic material, and thus the pressure inside the connection tube 150 is lowered as before. Air or toothpaste should be introduced into the connecting tube 150 from the outside due to the pressure difference from the outside, but also the air is prevented from being introduced by the second check valve 141 and the first check valve 121 is forwarded. Passed toothpaste enters into the connection tube (150). By repeating such an operation, the toothpaste intermittently introduced from the tubular toothpaste may be intermittently discharged through the second check valve 141.

On the other hand, the operation to reduce the volume of the connecting tube 150 can be performed simply by pressing the connecting tube 150 in any direction. Alternatively, the operation of pressing the second housing 130 toward the first housing 110 along the axis connecting the centerlines of the first housing 110 and the second housing 130, that is, the position of the user. In the simple operation of pushing up the second housing 130, the volume of the connection tube 150 can be reduced. As illustrated in FIG. 4, when an external force is applied to the second housing 130 in the A direction, the connection tube 150 is pressed upward and downward to decrease the volume. When the external force in the A direction is removed, the connection tube 150 is removed. As it is restored to suck the toothpaste and fluid in the B direction. Furthermore, the operation of rotating the second housing 130 with respect to the first housing 110 is also possible. As illustrated in FIG. 5, when the second housing 130 is rotated in the C direction, the connecting tube 150 is twisted and the volume is reduced. Removing the rotational force is to restore the connection tube 150 while also sucking the toothpaste and fluid in the B direction. In this case, in order to facilitate the rotation operation of the second housing 130, it is preferable to install the handle 210a in the second housing 130 so as to rotate around the centerline of the second housing 130.

In order to make the operation of rotating the second housing 130 more smoothly, as illustrated in FIG. 6, the disc-shaped extension disk 210 is fixed to the second housing 130, and the handle 210a is disposed. It is more preferable to form the extension disk 210. The extension disk 210 may be manufactured by integrally molding the second housing 130 in the form of a flange extending from the outer circumference of the second housing 130. In addition, to facilitate the rotation of the extension disk 210, one end is fixed to the first housing 110, and the other end further comprises a support member 220 is extended to the extent that can contact the extension disk (210) desirable. The other end of the support member 220 may be in contact with the extension disk 210, and may be spaced apart at intervals of several mm. Even when the other end of the support member 220 is in contact with the extension disk 210, the support member 220 should not interfere with the movement of the extension disk 210. Whether the support member 220 and the extension disk 210 are in contact with each other or spaced at regular intervals, the vertical length of the connection tube 150 when the connection tube 150 is twisted while the extension disk 210 is rotated Can be appropriately determined depending on the degree of decrease. The supporting member 220 may be a simple rod shape or a hollow cylindrical shape. In the case of the cylindrical shape, the inner diameter of the supporting member 220 should be larger than the outer diameter of the connection tube 150. In particular, when the support member 220 is a cylindrical member, the cylindrical protrusion 211 is formed from the extending disk 210 so that the cylindrical protrusion 211 is engaged with the inner diameter side of the support member 220. By doing so, it is preferable to maintain a constant rotation center axis while the second housing 130, that is, the extension disk 210, rotates.

7 is a cross-sectional view of another embodiment for smoothly rotating the extension disk 210. The extension disk 210 is fixed to the second housing 130 as in the previous embodiment of FIG. 6, but further includes a rotation support member 230, and the rotation support member 230 and the support member ( 220 is configured to be secured together to another member called fixing plate 240. The rotation support member 230 is disposed spaced downward from the support member 220, and has a through hole formed therein so that the al end of the second housing 130 is inserted therein so that the second housing 130 can rotate. The extension disk 210 is disposed between the support member 220 and the rotation support member 230. Since a part of the second housing 130 is inserted into the through hole of the rotation supporting member 230, the second housing 130 serves as a rotation axis with respect to the extension disk 210, and as a result, the extension disk 210 can rotate smoothly. Can be. 8 is a front view of FIG. 8 and a side view of FIG. 9, and reference numeral 50 denotes a tubular toothpaste container.

On the other hand, in any embodiment, in order to rotate the extension disk 210, instead of the handle (210a) may be additionally installed an electric mechanism. For example, the pinion is provided with a motor coupled to the teeth, and the teeth formed on the outer periphery of the extension disk 210, when the pinion of the motor meshes with the teeth of the extension disk 210 to rotate the extension disk 210 by electricity. Can be. In this case, if the tooth is removed from some of the outer circumferential surface of the pinion, even if the motor is continuously rotated in one direction, the extension disk 210 may be rotated at a predetermined angle and then returned to its original position.

One embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms. Accordingly, such improvements and modifications will fall within the scope of the present invention as long as they are obvious to those skilled in the art.
