Description

an oral liquid bottle

technical field

The utility model belongs to the field of glass bottles, in particular to the field of medicinal oral liquid bottles.

Background technique

At present, the bottle caps of oral liquid bottles used in my country's pharmaceutical industry are mainly composed of aluminum caps and rubber pads. This oral liquid is prone to side leakage at the bottle mouth; there are also internal plug-type seals, which are not vacuum-packed. The inner wall of the bottle mouth of the glass bottle is smooth, and it is prone to jumping plugs and rubber plugs that cannot be fully pressed into the neck of the bottle. At the same time, the top surface of the bottle mouth of the glass bottle is smooth, and the sealing stability between it and the sealing surface of the rubber stopper is poor, so that the rubber stopper is subjected to uneven force when the aluminum cap is sealed, and the sealing reliability is poor.

SUMMARY OF THE INVENTION

The technical problem to be solved by the utility model is to provide an oral liquid bottle structure with good sealing performance of the bottle cap and no jumping of the plug.

The utility model adopts the following technical solutions for solving the above-mentioned technical problems:

An oral liquid bottle includes a bottle body, a bottle bottom, a bottle neck, a bottle shoulder and a bottle mouth, and is characterized in that it also includes a rubber stopper for sealing, the rubber stopper includes an inner stopper structure, and the outer circumference of the inner stopper is provided with At least one fine groove structure extending from the middle of the outer circumference of the inner plug to the bottom of the inner plug.

Further, the bottom of the thin groove structure and one side surface of the thin groove structure are open, and one side surface of the thin groove structure is connected to the inner wall of the bottle neck during installation.

Further, the outer edge of the upper part of the bottle neck is provided with at least one circle of inverted tooth-shaped protrusions, and the rubber stopper further includes an outer casing part, an inner groove structure is formed between the inner plug and the outer casing, and the top of the inner groove structure is sealed, so The upper part of the bottle neck is inserted into the inner groove.

Further, the surface of the inner groove is provided with a ring that fits with the inverted tooth-shaped protrusion.

Further, the inner surface of the bottle bottom is a downwardly concave arc-shaped structure.

Further, the bottle shoulder is an inclined structure of 30°-55° with the bottle body.

Further, the corners on the inner surface of the bottle are all arc structures.

Compared with the prior art, the utility model has the following beneficial effects:

1. The utility model is provided with a thin groove on the inner plug. When the inner plug is installed, part of the air pressure will enter the thin groove, forming a downward opposing pressure, so that the rubber plug can be pressed down smoothly.

2. The inner surface of the bottle bottom has a downwardly concave arc-shaped structure. Compared with the ordinary upwardly concave bottle bottom structure, the downwardly concave structure will not have excessive liquid residue during use.

3. The bottle shoulder is designed as an inclined structure, which is different from the ordinary horizontal bottle shoulder, which can make the liquid flow down faster, and no liquid residue will be produced on the bottle shoulder.

Detailed ways

The structure and working process of the present utility model will be further described below in conjunction with the accompanying drawings.

Figure 1: An oral liquid bottle includes a bottle body 1, a bottle bottom 2, a neck 3, a bottle shoulder 4, a bottle mouth, and an arc-shaped structure with the inner surface of the bottle bottom concave downward. The bottle shoulder is an inclined structure of 30°-55° with the bottle body. The corners on the inner surface of the bottle are all arc structures.

As shown in Figure 2: the oral liquid bottle further includes a rubber stopper 5 for sealing, the rubber stopper includes an inner stopper structure 6, and the outer circumference of the inner stopper is provided with at least one fine groove structure 7 extending from the middle of the inner stopper to the bottom of the inner stopper. The bottom and one side of the thin groove structure are open. During installation, one side of the thin groove structure is connected to the inner wall of the bottle neck, and the air in the bottle body enters the groove cavity through the bottom surface of the thin groove structure. When the liquid in the bottle exceeds the shoulder of the bottle, the liquid in the bottle enters the groove cavity through capillary action, which ensures the stability of the rubber stopper and further ensures the sealing.

The outer edge of the upper part of the bottle neck is provided with at least one circle of inverted tooth-shaped protrusions 8, and the rubber plug also includes a casing part 9. An inner groove structure is formed between the inner plug and the outer casing, the top of the inner groove structure is sealed, and the upper part of the bottle neck is inserted into the inner groove. The surface of the inner groove is provided with an inverted tooth-shaped protrusion that fits.

Among them, the shoulder of the bottle is inclined at 30°-55° to the bottle body, which makes it easier for the liquid to flow down without hanging on the bottle. If the angle is less than 30°, the liquid is easy to stay at the shoulder of the bottle. If the angle is greater than 55°, the bottle mouth is too large and does not meet the standard. .

The above-mentioned embodiment only expresses an embodiment of the present invention, and its description is specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
