Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid dispensing device that can store liquid in a sealed state and divide the liquid into small portions at any time.

[Conventional technology]

Conventionally, liquid dispensing devices have either used a ground glass stopper at the opening of the main container, or fitted the lid externally to the main container through a packing material in order to maintain a sealed state when storing the liquid. There are some that are screwed together depending on the condition.

[Problem that the invention attempts to solve]

However, the above-mentioned ground glass stoppers require a high degree of dimensional accuracy in order to maintain a sealed state, are expensive and easily damaged, and must be handled with great care. For items that are screwed together in an externally fitted state, the seal cannot be maintained unless it is strongly tightened, and the material of the lid body is limited to metal or synthetic resin due to its dimensional accuracy and strength, so for example perfumes etc. are not sold over the counter. If you want to place it in a store for decoration purposes, or if you want to make something decorative with ceramics or ceramics, the structure of the lid is made up of a separate material and covered with a cover, which makes the structure complicated. It was also inconvenient to handle. Furthermore, when dispensing liquids, simply installing an outlet pipe with an on-off valve on the side wall of the container will prevent the liquid from flowing from inside the container to the outside when dispensing small amounts of expensive liquids such as perfume. It was very difficult to finely adjust the flow rate.

In view of the above-mentioned problems, the present invention has a simple structure, the lid is easy to open and close, and is easy to handle.It also maintains hermeticity and can store even volatile liquids for a long period of time, while reducing the flow rate. It is an object of the present invention to provide a liquid dispensing device which can be finely adjusted and dispensed into appropriate amounts, and which is also aesthetically pleasing.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention comprises a main body container for storing liquid, which has an opening at the upper part with an upright wall around the periphery, and a main body container that protrudes from the side wall of the main container and penetrates into the inside of the outer covering member. an operating shaft having a screw hole provided in a side wall of the outer sheath member and an operating piece provided at a base end thereof, the pipe being made of a soft material forming a liquid lead-out path communicating from the inside of the main body container to the outside being installed in the hole; are rotatably screwed together, and by rotating the operating shaft using the operating piece, the tip of the operating shaft is brought into contact with the pipe, and the pipe is pressed so that the pipe can be closed by the pressing part. It is an object of the present invention to provide a liquid dispensing device comprising a pipe, a lid body having an annular fitting piece on the lower surface that can be fitted onto the opening vertical wall of the main container, and a soft sealing material adhered to the inner surface of the fitting piece. It is something to do.

[Effect]

Since the configuration of the present invention is as described above, the operation shaft is rotated by the operation piece of the outlet pipe to press the internal pipe into a flat shape, and with the liquid outflow path closed by the pressing part, the main body Liquid is injected from the opening at the top, and the annular fitting piece of the lid body is fitted to the vertical wall of the opening, thereby storing the liquid in a sealed state inside the main container. In order to subdivide the liquid in the main body container, the operating shaft of the outlet pipe protruding from the side wall of the main body is rotated in a direction to release the pressure on the internal pipe, and the liquid outlet path is opened in the main body. By communicating from the inside of the container to the outside, liquid flows from inside the main container to the outside. At this time, the flow rate of liquid from the outlet tube can be adjusted by appropriately adjusting the amount of rotation of the rotation shaft.

〔Example〕

The details of the present invention will be explained based on further illustrated embodiments.

FIG. 1 is a perspective view of one embodiment of the liquid dispensing device according to the present invention, in which 1 is a main container, 2 is a lid body,
Reference numeral 3 denotes an outlet pipe protruding from the side wall 11 of the main container. The main container 1, the lid 2, the outer cover member of the outlet tube 3, and the operating piece 41 described below are all made of hard materials. For example, it is made of ceramics, earthenware, porcelain, etc., but it may also be made of hard synthetic resin, metal, etc. However, when used for selling perfumes and the like in small portions at a store, it is preferable to use ceramics, china, etc., and to make each part of the same material, giving a favorable appearance. In addition, in this embodiment, the main container has a substantially cylindrical shape, and the lid part has a substantially hemispherical shape like an overturned bowl, so that the connecting part between the main container 1 and the lid body 2 is shielded, which is preferable in terms of appearance. However, these shapes are not limited in any way; the main body container 1 only needs to have a space that can accommodate liquid inside, and various shapes can be adopted, and the shape of the lid body can be The same is true.

FIG. 2 is a side sectional view of the liquid dispensing device. Below the approximate center of the side wall 11 of the hollow main container 1, there is provided an outlet pipe 3 that protrudes laterally in an approximately horizontal direction and has a tip bent downward. ing. Further, a cylindrical annular standing wall 13 is protruded from approximately the center of the upper surface 12 of the main container 1, with the upper surface serving as an opening and the end portion serving as an opening edge 14. The lid body 2 that tightly fits into the upper opening standing wall 13 of the main body container 1 has a substantially cylindrical standing wall facing downward on the inner lower surface of the substantially hemispherical cover portion 21, forming an annular fitting piece 22, A soft sealing material 2 is provided on the inner surface 23 of the fitting piece 22 and the lower surface of the cover part 21.
4 is attached and formed. 3A and 3B are enlarged sectional views of the upper part of the device, and as shown in the figure, the annular fitting piece 22 provided on the lower surface of the cover part 21 of the lid body 2 can be fitted onto the opening vertical wall 13 of the main container 1. Any shape is acceptable, but the illustrated one has an annular fitting piece inner surface 23.
A soft sealing material 24 is formed on the inner surface by tilting the annular fitting piece 22 downward and inward so that the planar shape of the lower end of the annular fitting piece 22 is substantially the same as the opening edge 14 of the main container 1.
from the lower part of the annular fitting piece 22 to the cover part 21 of the lid body 2
A tapered abutment surface 25 that is inclined downward and outward is formed over the lower sealing material surface. Due to the combination of the annular fitting piece 22 and the soft sealing material 24 of this embodiment, the surface of the sealing material 24 has an inclined surface in the downward and outward direction, and as it approaches the upper part of the sealing material 24, its thickness increases and its elasticity increases. Therefore, when fitting the annular fitting piece 22 of the lid body 2 to the opening vertical wall 13 of the main container 1, as shown in FIG. A sealed state can be achieved simply by fitting from above, and by forming a recess 15 by forming an inverted tapered portion in which the vertical opening wall 13 of the main container 1 is inclined downward from the opening edge 14, As shown in FIG.
This makes the airtight state more reliable and makes it difficult for the lid 2 to come off from the main container 1. Further, as in this embodiment, the soft sealing material 24 does not necessarily have to be formed on the entire lower surface of the cover part 21 inside the annular fitting piece 22, but only on the inner wall of the annular fitting piece 22 or on the inner wall of the annular fitting piece 22 and the cover part. 21
It is sufficient to simply form it on the lower surface where the opening edge 14 of the main container 1 comes into contact.

The soft sealing material 24 is a soft material that has properties such as solvent resistance depending on its sealing performance and the type of liquid to be stored when fitting the lid 2 to the main container 1 and sealing it. If available, various types may be used. For example, there is no limit to the use of silicone rubber or other soft synthetic resins.
However, this soft sealing material 24 contains silicone rubber, especially methylvinyl polysiloxane as a main component, methylhydrogen polysiloxane as a crosslinking agent, silicon dioxide as a filler, a platinum compound as a catalyst, and silanol groups and amino groups as an adhesive aid. It is preferable to use silanes or silicone rubber using a tin-based compound as a reaction control agent. As this silicone rubber, Shin-Etsu silicone rubber
There is KE-1251 (trade name of Shin-Etsu Chemical Co., Ltd.), and this silicone rubber is a one-component heating self-adhesive type that can be cured and bonded in a short time by applying a temperature of 100℃ or more. , which is a rubber elastic body, and it can be said that it is preferable to use this material as the soft sealing material of the present invention in terms of its intended use. However, the present invention is not limited to this material as a soft sealing material.

Further, as shown in FIG. 4, the outlet pipe 3 protruding from the side wall 11 of the main container 1 is made by bending the tip of the outer cover member 31 made of the same material as the main container 1 and the lid 2 downward, and opening the tip. A metal base tube 32 is inserted into the interior, and the base end of the base tube 32 is inserted into the hole 13 opened in the recess 12 formed in the side wall 11 of the main body container 1 through the mounting bracket 39. It is attached to the main body container 1 by fitting and fixing it so that it faces inside. A hole 33 is provided inside the base tube 32, and a pipe 34 made of a soft material such as silicone rubber is inserted into the hole 33 from inside the main container 1 through the base tube 32. Further, a pipe 35 is installed in series,
The tip of the pipe 35 projects downwardly from the tip opening of the outer sheathing member 31 to form a liquid lead-out path from the main container 1 to the outside. Also, base tube 3
A nut member 38 with a screw hole 36 inside that reaches the hole 33 is embedded in the upper side of 2, and an opening 37 is provided in the outer covering member 31 at a position corresponding to the screw hole 36, and a flow rate adjustment rod is inserted through the opening 37. The operation piece 41 of No. 4 is threaded on the outer surface to fit the screw hole 3 of the nut member 38.
A shaft 42 that can be screwed into the shaft 42 is provided in a protruding manner, and a hole 43 is provided in at least the tip portion of the shaft 42, and a disc-shaped lower surface of the hole 43 is brought into contact with the pipe 34, and a protrusion is provided approximately in the center of the upper surface of the hole 43. The protrusion of the protruding pressing member 44 is rotatably fitted to form an on-off valve. In the outlet pipe 3 constructed in this way, by rotating the operation piece 41 of the flow rate adjustment rod 4, the shaft 42 provided on the knob 41 moves up and down within the screw hole 36 of the nut member 38, and the shaft 42 is moved up and down within the screw hole 36 of the nut member 38. The pressing member 44 at the tip of 42 presses or releases the side surface of the pipe 34 made of soft material, and the pipe 34
The liquid outlet path is opened and closed in an adjustable manner by deforming it into a flat shape using a pressing part. Here, since the pipe 34 is made of a soft material, by strongly pressing it with the pressing member 44, the pipe 34 is completely flattened and closed, and the liquid contained in the main body container 1 does not leak, and the main body container 1 can be maintained in a sealed state. Further, since the flow rate is adjusted steplessly by threading the nut member and the shaft, delicate flow rate adjustment is possible, which is very convenient when dispensing expensive liquids such as perfume into small portions. In this embodiment, the nut member 38 is a separate member from the base tube 32, but the screw hole may be formed directly in the base tube 32. Also, although the pipe 34 and the pipe 35 are separate members, a single pipe may be used,
In addition, the material of these pipes can be made of various synthetic rubbers or synthetic resins as long as they are soft and durable against the liquid contained in the main body container 1. Hole 13 in container side wall 11, mounting bracket 39 and pipe 34
If the surrounding area is sealed with a sealant 45 such as silicone or an adhesive, the seal can be more securely sealed.

When the liquid dispensing device of the above embodiment is used, the pipe 34 is closed by the flow control rod of the outlet pipe 3 provided on the side wall 11 of the main body container 1, and the liquid is discharged from the upper opening of the main body container 1. When the lid body 2 is injected into the main container 1 and the fitting piece 22 is fitted onto the opening vertical wall 13 of the main container 1 from above, the inner tapered abutting surface 25 of the soft sealing material 24 will close to the main container 1. 1 and apply pressure in the fitting direction, the soft sealing material 24 is compressed at the same time as the degree of fitting into each other becomes large, and the compressed portion extends upward from the compressed position of the abutment surface 25 or While escaping downward and further from the opening edge 14 of the opening vertical wall 13 of the main body container 1 to the recess 15 formed by sloping downward and inward, the degree of sealing is increased, and the pipe 34 of the outlet pipe 3 is closed and the main body To improve the degree of sealing of a container 1 and to make it difficult for a lid 2 to come off. Further, by adjusting the degree of pressure of the pressing member 44 on the pipe 34 using the screw hole 36 and the shaft 42, it is possible to completely close the pipe 34 and to control the flow rate steplessly. Further, since the main body container 1 has a simple opening structure and can maintain high sealing performance, a high degree of dimensional accuracy is not required, and a liquid dispensing device with a favorable appearance can be manufactured using ceramics, china, etc.
