Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closure lid applied to a medicated bottle or other bottle containing a liquid, and more particularly to a bottle lid effective for preventing dripping.

[0002]

2. Description of the Related Art In a bottle containing a high-viscosity chemical solution or a high-sugar degree chemical solution, when the chemical solution is taken out, the high-viscosity chemical solution remaining on the bottle mouth crystallizes, and the bottle lid cannot be opened or closed accurately. It is often the experience that bottle maintenance becomes difficult to keep clean.

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 so that the inner stopper extends along the flange of the inner stopper. It has been proposed that the liquid that flows out is drained at the tip of the flange and is prevented from dripping to the outer periphery of the bottle mouth.

[0004]

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

[0005]

[Objective of the Invention] The present invention not only exhibits the effect of preventing dripping, but also allows the inner stopper to be inserted and inserted into the bottle lid with one touch, and moreover, when the bottle lid is attached, it is installed inside the bottle lid. An inner stopper for preventing liquid dripping is provided so that the stopper can be attached to the medicine bottle at the same time.

Another object of the present invention is to remove only the bottle lid when the drug solution or the like is taken out from the medicinal bottle, because the inner stopper attached to the bottle lid can be accurately left at the bottle mouth. It is intended to provide a bottle cap for preventing liquid dripping, which is configured to prevent the liquid from dripping outside from the bottle mouth portion when the liquid is taken out.

[0007]

The present invention comprises a combination of a bottle lid and an inner stopper, and the bottle lid is formed in an inverted dish shape and the thread groove of the bottle lid is formed with a thread groove for tightening inside the peripheral body portion. A plurality of locking claws are formed along the circumference above the inside of the container, and the inner plug has a thin wall at the upper end of a cylindrical barrel body having a size matching the inner diameter of the bottle mouth. The flange of the inner stopper is formed so that the outer peripheral portion has an outer diameter dimension that is long enough to fit with the locking claw formed on the inner upper end of the peripheral body portion of the bottle lid. The structure of the bottle lid to prevent dripping is the main point of the device.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

Reference numeral 1 denotes a bottle lid, and a screw groove 11 is formed on the inside of the body of a lid body formed in the shape of an inverted dish so as to match a screw thread 21 for mounting the bottle lid formed on the outer periphery of the bottle mouth 2. ing.

Denoted by 12 ... 12 are locking claws formed at a predetermined interval along the circumference (above the screw groove 11) at the upper end of the inner peripheral part of the bottle lid 1. ... 12 and the rear surface of the top plate of the bottle lid 1 (in the gap), the outer peripheral portion of the flange 32 formed at the upper end portion of the inner stopper 3 for preventing liquid dripping can be locked. (See FIGS. 2 and 3) The heights of the locking claws 12 ... 12 are the screw grooves 11 when observed in a plane as shown in FIG.
It is desirable to form it so that it is slightly higher than the height of the groove, and the cutting position is as shown in FIG.
It is desirable to form along 11 spiral inclinations.

The inner stopper 3 for preventing dripping is made 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. A thin ring-shaped flange 32 that abuts the end face of 2 is integrally formed.

The outer diameter of the ring-shaped flange 32 formed at the upper end of the barrel 31 is at least slightly larger than the outer diameter of the locking claw 12 formed at the upper inner end of the body of the bottle lid 1. Has an outer diameter that is as large as 0.5 mm, and is formed to overhang.

Numerals 33 and 33 are sealing ridges formed on both upper and lower surfaces of a ring-shaped flange 32 in a thin annular shape so as to follow the shape thereof. When the bottle lid 1 is mounted, the bottle lid 1 is attached.
This is to further enhance the sealing effect (sealing effect) of closely contacting the back surface of the top plate and the upper surface of the bottle mouth portion 2.

It is not essential for the present invention to form annular sealing projections 33, 33 on the upper and lower surfaces of the flange 32.

[0015]

The effects of the present invention having the above-described structure are as follows.

(1) At the upper end of the inner peripheral portion of the body of the bottle lid 1, locking claws 12 ... 12 are formed so as to project along the circumference (above the screw groove 11) at predetermined intervals. Inner stopper 3 for preventing liquid dripping (in the gap) between the claws 12 ... 12 and the back surface of the top plate of the bottle lid 1
Since the outer peripheral portion of the flange 32 formed at the upper end portion of the stopper is configured to be locked and the height of the locking claws 12 ... 12 is formed to be higher than the height of the screw groove 11, the inner plug 3 is bottled. When mounting inside the lid 1, if the flange 32 portion of the inner stopper 3 is forcedly pushed from the lower surface of the bottle lid 1, the outer peripheral portion of the flange 32 will be the bottle lid 1.
While overcoming the thread groove 11 formed on the inside, it instantly reaches the locking claws 12 ... 12 and can be locked accurately, and it has the feature of exhibiting excellent one-touch performance that cannot be expected with conventional inner plugs. is there.

(2) When the bottle lid 1 is attached to the medicine bottle, 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, so that it is the same as the conventional packing. It can exert its function and prevent the liquid in the bottle from leaking outside during storage or transportation.

(3) When the tightening of the bottle lid 1 is released to take out the liquid contained in the bottle, the bottle lid 1 is locked by the locking claws 12.
… 12, the screw thread 21 and the flange 32 are used as guides to rotate and be removed. The inner stopper 3 automatically remains on the bottle mouth 2 side without any special operation to prevent dripping. It can function as an inner stopper.

(4) Flange formed on the upper end of the barrel 31
32 is formed as a thin plate shape and interrupts the continuity with the upper end of the bottle mouth 2, so it is a flange when the liquid is taken out.
The liquid flowing out to the 32 portion is drained at the tip (outer peripheral portion) of the flange 32, and the effect of preventing it from dripping outside from the bottle mouth 2 portion can be exerted. Further, when closing the bottle mouth portion 2 after taking out the liquid, if the bottle lid 1 is attached according to a well-known method, the outer peripheral portion of the flange 32 has the same function as the screw thread 22 formed on the outer periphery of the bottle mouth 2. There is an advantage that the bottle lid 1 can be easily tightened while exhibiting the above, and the attachment of the bottle lid 1 is not hindered by the presence of the inner stopper 3.
