Description

Technical field

A useful model relates to a stopper for sealing bottles used for beverages.

BACKGROUND OF THE INVENTION

A beverage bottle stopper is known, including a profile cap consisting of an outer body enclosing an inner body, with an annular bed formed between them. The length of the inner body is smaller than the length of the outer body, with the outer outer surface of the inner body being cylindrical-conical. In the annular bed is placed the upper part of the hollow body, in which is formed a ring-shaped limiter, and next to it is formed a sealing ring, formed as a whole with the upper part of the hollow body, which through its front surface in the range of the annular limiter rests tightly on the front inner surface of the annular bed. An intermediate part is formed below the upper hollow body and thereafter there is a lower conical part, formed as a truncated cone, with the outer diameter of the annular stop being larger than the outer diameter of the sealing ring. The profile cap is formed of a durable plastic material and the hollow body is made of soft plastic material [1].

The technical nature of the utility model

The bottle closure includes a profile cap made up of an outer body enclosing an inner body, with a ring-shaped bed formed between them, and the length of the inner body being smaller than the length of the outer body. The outer circumferential surface of the inner body is shaped like a cylindrical cone, and in the annular bed is placed the upper part of the hollow body, in which the annular stop is formed. Next to the limiter is a sealing ring formed as a whole with the upper part of the hollow body, which by its front surface in the circumference of the annular limiter rests tightly on the front inner surface of the annular bed. The inner surface of the upper hollow body within the range of the sealing ring is rolled up, and an intermediate part and a lower conical part are formed below the upper hollow body, which is designed as a truncated cone, with the outer diameter of the annular stop being larger than the annular stop. the outer diameter of the sealing ring. According to a useful model, the inner circumferential surface of the outer body is ribbed, with the shaped support ribs arranged in a concentric circle relative to the outer body and parallel to the vertical axis and their length less than the depth of the profile cap. The cylindrical portion of the outer circumferential surface of the inner body is ribbed, and the outer surface of the sealing ring is concentrically tightly enclosed by the supporting ribs.

Another aspect of the invention is that the support ribs at the front end in the direction of the annular bed are sharpened and their thickness is from 1.52 to 1.95 times smaller than the distance between two adjacent support ribs.

In a further embodiment, a thin-walled ring is formed on the front inner surface of the annular bed of the profile cap, in the area where the hollow body front surface is glued.

The advantages of the utility model are that a better connection and sealing is achieved between the profile cap and the hollow body due to the presence of support ribs, a ribbed outer surrounding surface of the inner body, as well as a ribbed inner surface of the upper body of the hollow body , which prevents removal of the profile cap only and the hollow body remains in the neck of the bottle. In addition, this effect is magnified when also attaching the hollow body front surface to the front inner surface of the annular bed in the area of the thin-walled ring, which is used predominantly for the closure of more expensive beverages. In addition, the cap can more easily be removed from the neck of the bottle, which is accomplished both by pulling and rotating the profile cap, since a better adhesion is created between the inner surrounding surface of the outer body of the cap and the outer surface. of the sealing ring through the support ribs, which prevents the cap from rotating relative to the sealing ring.

Examples of implementation of the utility model

The bottle cap consists of a profile cap 1 formed by an outer body 2 enclosing an inner body 3 having an annular bed 4 between them. The length of the inner body 3 is smaller than the length of the outer body 2 whose inner the circumferential surface 5 is ribbed, with the shaped support ribs 6 being arranged in a concentric circle with respect to the outer body 2 and parallel to the vertical axis 7. The support ribs 6 at their anterior end are pointed / not shown in the figures / in the direction of the annular bed 4, such as the length and me smaller from the depth of the profile cap 1, and the thickness / width / of the support ribs 6 on the side of the inner surface 5 of the outer body 2 is 1.85 times less than the distance between two adjacent support ribs 6. On the inner inner surface 8 of the annular bed 4 a thin-walled ring is formed 9. The outer surface 10 of the inner body 3 is shaped like a cylindrical cone and the cylindrical portion is ribbed. In the annular bed 4 is placed the upper part 11 of the hollow body 12, in which is formed a ring limiter 13 and next to it is formed a sealing ring 14, formed as a whole with the upper part of the hollow body 12, which through its front surface 15 in range of the annular stop 13 rests tightly on the front inner surface 8 of the annular bed 4 and completely covers the thin-walled ring 9. The outer surface 16 of the sealing ring 14 is concentrically tightly enclosed by the support ribs 6 and the inner surface 17 of the upper ring 17. part 11 of the hollow body 12 within the circumference of the seal ring 14. An intermediate part 18 is formed below the upper part 11 in the hollow body 12, and after that a lower cone part 19 is formed, formed as a truncated cone on which the ratio between the small and the large base is equal to 0.45. The outer diameter of the annular stop 13 is larger than the outer diameter of the sealing ring 14, and the inner diameter of the hollow body 12 in the area of the sealing ring 14 is larger than the inner diameter of the rest of the hollow body 12. Profile cap 1 is made of harder plastic material than plastic material used to make the hollow body 12.

Using the utility model

The utility model works as follows.

After making the profile cap 1 and the hollow body 12, the body 12 is inserted into the annular bed 4 and pressed until the annular stop 13 rests tightly on the front surface 8 of the annular bed 4 and the inner surface 17 of the upper part 11 of the hollow body 12 encloses completely the outer circumferential surface 10 of the inner body 3, wherein the outer surface 16 of the sealing ring 14 is pressed entirely by the support ribs 6. The conical part 19 of the hollow body 12 is then inserted into the neck of the bottle and pressed until then the sealing ring 14 rests snugly on the front surface of the bottle neck. The cap from the bottle is removed simultaneously by pulling and rotating the cap 1.

In the case where adhesion is applied between the front inner surface 8 in the area of the thin-walled ring 9 and the front surface 15 of the hollow body 12, it occurs before the annular stop 13 is pressed against the front inner surface 8 of the annular bed 4.
