The outer diameter is defined as an outer diameter dimension that can be fitted into the thread groove 11 formed on the inner peripheral portion of the bottle lid 1. [Effect] It can be attached to the bottle lid with one touch, and when the bottle lid is removed, the inner stopper remains at the bottle mouth portion and the effect of preventing liquid dripping can be exhibited.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a closure lid applied to a medicated bottle or other bottle containing a liquid, and particularly to a bottle lid effective for preventing dripping.

[0002]

[Prior art]

 For bottles containing high-viscosity chemicals or high-sugar-concentration chemicals, when the chemicals are taken out, the high-viscosity chemicals that remain on the mouth of the bottle crystallize, making it impossible to open and close the bottle lid accurately, and to manage the bottles. Difficulty performing clean is often an experience.

As a means for solving these problems, an inner stopper having a thin-walled flange overhanging at the upper end of a cylindrical barrel is attached to the mouth of the bottle to install the flange of the inner stopper. The liquid flowing out along the line is drained at the tip of the flange to prevent it from dripping to the outer circumference of the bottle mouth.

[0004]

[Problems to be solved by the device]

 However, since the inner stopper that has been used conventionally has a structure independent of the bottle lid, the medicinal bottle, the inner stopper and the bottle lid must be prepared separately when manufacturing the drug solution, and the bottle filled with the drug solution must be prepared. However, there was a drawback that complicated work was required to first attach the inner stopper and then tighten the bottle lid having a different structure.

[0005]

[The purpose of the device]

 The present invention not only exhibits the effect of preventing liquid dripping, but also allows the inner stopper to be inserted and inserted into the bottle lid with one touch, and when the bottle lid is attached, the inner stopper installed inside the bottle lid is simultaneously used. It is intended to provide an inner stopper for preventing dripping, which is configured to be attached to the.

Another object of the present invention is that the inner stopper attached to the bottle lid can be accurately left at the bottle mouth portion when the liquid medicine is taken out from the medicated bottle, and the liquid is taken out when the liquid in the bottle is taken out. It is intended to provide a bottle cap for preventing liquid dripping, which is configured to prevent dripping from the outside.

[0007]

[Key points of the device]

 The present invention is a well-known bottle lid that is formed in the shape of an inverted dish and has a thread groove for tightening inside the peripheral body part, and the upper end of the cylindrical body part that has a size matching the inner diameter of the bottle mouth part. It consists of a combination of an inner stopper with a thin flange overhanging, and the outer periphery of the inner stopper flange is of a length that allows it to fit into the thread groove formed on the inner periphery of the peripheral body of the bottle lid. The point of the invention is the structure of the bottle lid for preventing liquid dripping, which is formed to have a diameter.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 is a known bottle lid, and a screw groove 11 formed on the outer periphery of the bottle mouth portion 2 and matching with a thread 21 for mounting the bottle lid is formed on the inside of the body portion of the lid body formed in the shape of an inverted dish. Is forming.

Reference numeral 3 denotes an inner stopper for preventing liquid dripping, which is formed of a synthetic resin or the like, and is provided on the upper end of a cylindrical barrel 31 having a size matching the inner diameter of the bottle mouth portion 2 and the bottle mouth portion 2 A thin ring-shaped flange 32 that abuts the end face of the is integrally formed.

The outer diameter of the flange 32 formed in a ring shape on the upper end of the cylindrical copper 31 is the outer diameter that matches the depth of the thread groove 11 formed inside the body portion of the bottle lid 1, or the outer diameter of the thread groove 11 The outer diameter is slightly larger than the outer diameter that matches the depth, specifically, it is oversized by 0.5 mm.

Reference numerals 33 and 33 denote sealing ridges formed on both upper and lower surfaces of the ring-shaped flange 32 in a thin annular shape so as to conform to the shape of the flange 32. The purpose is to further enhance the sealing effect (sealing effect) of bringing the back surface of the plate and the upper surface of the bottle mouth portion 2 into close contact with each other.

It should be noted that it is not essential to the present invention to form annular sealing protrusions 33, 33 on both upper and lower surfaces of the flange 32.

[0014]

[Effect of device]

 The effects of the present invention having the above configuration are as follows.

(1) The outer diameter of the flange 32, which is connected to the upper end of the barrel 31 of the inner stopper 3 in a ring shape, is larger than the inner diameter of the body of the bottle lid 1, that is, the outer diameter of the bottle lid 1. Since the outer diameter is formed so that it can be fitted in the thread groove 11 for mounting the bottle lid formed on the inner circumference of the body portion, and the flange 32 is formed thin, when the inner plug 3 is fitted and mounted in the bottle lid 1, If the flange 32 of the inner stopper 3 is forcibly pushed in from the lower surface of the bottle lid 1, the outer peripheral portion of the flange 32 is pushed down by the thread groove 11 formed inside the bottle lid 1 and easily reaches the upper end. The flange 32 that can be inserted and has been inserted into the bottle lid 1 is easily restored to its original shape by the resilience of the material, and the restored flange 32 is in the groove of the screw groove 11 of the bottle lid 1. It has a function of being locked and integrated in the bottle lid 1 accurately.

(2) Especially, when the outer diameter of the flange 32 is set to be slightly larger than the outer diameter of the bottle lid 1 that can be fitted into the thread groove 11 of the bottle lid 1, the fitted state with respect to the bottle lid 1 can be further strengthened. It

(3) With the bottle lid 1 attached, the flange 32 portion is interposed between the upper end surface of the bottle mouth 2 and the inner side surface of the bottle lid 1, and thus exhibits the same function as conventional packing. It is possible to prevent the liquid in the bottle from leaking to the outside during storage or transportation.

(4) When the tightening of the bottle lid 1 is released in order to take out the liquid contained in the bottle, the bottle lid 1 is rotated by using the screw thread 21 and the flange 32 as a guide, and is removed. Even if the operation is not performed, the inner stopper 3 automatically remains on the bottle mouth 2 side and can function as an inner stopper for preventing dripping.

(5) The flange 32 formed on the upper end of the cylinder body 31 is formed as a thin plate shape, and its continuity with the upper end of the bottle mouth 2 is cut, so that it flows out to the flange 32 portion when the liquid is taken out. The liquid is drained at the tip portion (outer peripheral portion) of the flange 32, and the effect of preventing the liquid from dripping outside from the bottle mouth 2 portion can be exhibited. When the bottle mouth 2 is closed after the liquid is taken out, the bottle lid 1 is attached according to a well-known method so that the outer periphery of the flange 32 is similar to the screw thread 22 formed on the outer periphery of the bottle mouth 2. The bottle lid 1 can be easily tightened while exerting its function, and there is an advantage that the attachment of the bottle lid 1 is not hindered by the presence of the inner stopper 3.
