Description

The present invention - the cap "Pint", relates to the field of food and medical industry and can be used to seal bottles with screw threads on the neck.

Known cap with screw thread, designed for capping PET bottles (1). The disadvantage of this cap can be considered that, if necessary, you can not affect the contents of the corked bottle without violating the isolation of the contents of the bottle from the external environment.

The PAM plug is known as an autonomous mixing device designed for separate storage and dissolution of substances in a liquid in a bottle without violating the isolation of the contents of the bottle from the external environment (2). It can be considered a disadvantage that it cannot be used for bottles with screw threads on the neck.

The objective of the invention is the creation of "Autonomous Mixing Device", adapted for bottles with screw threads on the neck. The task is solved using the cap "Pint". According to the purpose, it can have two options: for liquid substances - in capsules of film material; for solids - powdered or granular. The mechanism of the “Pint” cap can be applied to screw cap caps for PET bottles of any capacity. Moreover, for PET bottles with a volume of 5 liters or more, having a wider neck, and, accordingly, a larger cap, it is possible to use similar mechanisms that provide separate storage and introduction of a larger number of components into the solution.

The “Pint” cap for liquid substances enclosed in a capsule of film material is illustrated by the drawings:

Figure 1 - General view;

Figure 2 is a General view in section;

Figure 3 - in the assembled state in the context;

Figure 4 - in working condition in section.

General view of the cap "Pint" for liquid substances is illustrated in Figure 1, where the positions indicated:

Pos.1 - neck of the bottle;

Pos. 4 - screw rod handle.

A general sectional view of the “Pint” cap for liquid substances is illustrated in FIG. - 2, where the positions indicated:

Pos. 1 - bottle neck.

Pos.2 - case - solid product. On the outer surface of the upper part of the body there is an annular recess with a toothed surface 8. On the inner surface of the wall of the body there is a screw thread 6 for screwing on the neck of the bottle. The bottom of the housing has a circular hole formed by a central tube 5 extending parallel to the O-O axis. On the inner surface of the upper part of the Central tube there is a screw thread 7 for installing a screw rod 10.

Pos.3 - protective gear tape. The toothed belt has protrusions and depressions that correspond to the toothed surface in the annular recess 8 on the housing 2 and the toothed surface in the annular recess 9 on the handle of the screw rod 4. Entering into engagement with the toothed surface in the annular recess on the body and on the handle of the screw rod, prevents rotation screw rod relative to the housing.

Pos.4 - handle screw rod, made in the form of a disk whose diameter is equal to the outer diameter of the housing.

Pos. 5 - central tube.

Pos.6 - screw thread on the inner surface of the housing wall.

Pos.7 - threaded part of the central tube.

Pos.8 - an annular recess with a serrated surface on the housing.

Pos.9 - an annular recess with a serrated surface on the handle of the screw rod.

Pos.10 - screw rod, is a rod with a screw thread, coming from the bottom surface of the handle of the screw rod 4.

Pos.11 - freely protruding end of the gear belt for ease of removal.

Pos.12 - a disk piston, made in the form of a disk of a certain thickness, the diameter of which is equal to the inner diameter of the central tube.

Pos.13 - a capsule of film material, contains a liquid substance intended for dissolution.

Pos. 14 - support ring.

Pos.15 - punch, is a plate, curved convex side down. In the middle of the plate there is a hole on the edge of which there is one or several blades - spikes with sharp ends pointing up.

In the assembled state in the context of the cap "Pint" for liquid substances is illustrated in Figure 3. A screw rod 10 is installed in the threaded part 7 of the central tube 5. A disk piston 12 is installed below the central tube 5 until the surface of the disk piston touches the end of the screw rod 10. A capsule of film material 13 containing a liquid substance is placed inside the central tube 5 dissolution. A support ring 14 is installed below the capsule, which holds the capsule from displacement. A perforator 15 is installed on the end of the central tube 5. A protective gear belt 3 is installed in the annular recesses with the toothed surface 8 and 9. The cap “Pint” assembly is screwed onto the neck of the bottle 1.

The operation of the cap "Pint" for liquid substances is illustrated in Figure 4. To dissolve the substance enclosed in the capsule, remove the toothed tape. The screw rod is screwed in until it stops. When rotating along a thread, the helical rod moves down the O-O axis, exerting pressure on the disk piston and causing it to also move down. Moving, the disc piston compresses the capsule of film material underneath. Increasing hydraulic pressure inside the capsule will press its shell to the support ring. A further increase in pressure will lead to the punching of part of the capsule shell through the hole of the support ring and to the contact of the pressed part of the shell with the perforator blade, which will lead to puncturing of the shell - the formation of an opening through which the outflow of liquid substance into the bottle will begin. With further movement of the disk piston, the capsule shell will be wrinkled, the liquid substance will be completely squeezed out.

The prepared solution is still isolated from the external environment. To use the prepared solution, screw the case together with the screw stem from the neck of the bottle. The solution is poured through the open neck of the bottle.

The general view of the Pint cap for solids is illustrated by the drawings:

The General view of the cap "Pint" for dry substances in section is illustrated in Fig.6, where the positions indicated:

Pos. 1 - bottle neck.

Pos.2 - case - solid product. On the outer surface of the upper part of the body there is an annular recess with a toothed surface 8. On the inner surface of the wall of the body there is a screw thread 6 for screwing on the neck of the bottle. The bottom of the body has a circular hole formed by a central tube 5 extending parallel to the O-O axis. On the inner surface of the upper part of the Central tube there is a screw thread 7 for installing a screw rod 10.

Pos.3 - protective gear tape. Toothed tape has protrusions and depressions that correspond to the toothed surface in the annular recess on the housing and the toothed surface on the handle of the screw rod. Entering into engagement with the gear surface in the annular recess of the housing and the handle of the screw rod, prevents the rotation of the screw rod relative to the housing.

Pos.8 - an annular recess with a serrated surface on the housing.

Pos.9 - an annular recess with a serrated surface on the handle of the screw rod.

Pos.10 - screw rod, is a cylindrical rod with a screw thread, coming from the bottom surface of the handle of the screw rod 4.

Pos.11 - freely protruding end of the gear belt for ease of removal.

Pos.16 - the container is a hollow cylinder, the diameter of which is equal to the inner diameter of the central tube 5. There are holes in the cylinder wall 17. The height of the container — its volume, depends on the amount of substance intended for dissolution.

Pos.17 - hole in the wall of the container.

Pos. 18 - metal foil soldered to the end of the central tube and the bottom surface of the container.

In the assembled state in the context of the cap "Pint" for solids is illustrated Fig.7. A container 16 is installed in the central tube 5 so that the lower surface of the container is flush with the lower end surface of the central tube. The container is filled with the required amount of substance intended for dissolution. Since the diameter of the container is equal to the inner diameter of the Central tube, the inner surface of the Central tube, covering the surface of the container together with the holes, forms a closed space. For maximum isolation of dry matter from the liquid in the bottle, a metal foil 18 is soldered to the end of the central tube and the bottom surface of the container 18. A screw rod 10 is screwed into the threaded part 7 of the central tube 5 until the end of the screw rod contacts the container surface. A protective toothed belt 3 is installed in the annular recesses with the toothed surface 8 and 9. The “Cap” cap assembly is screwed onto the neck of the bottle 1.

The operation of the “Pint” cap for solids is illustrated in FIG. To dissolve the substance in the container, toothed tape is removed. The screw rod is screwed in until it stops. When rotating along a thread, the helical rod moves down the O-O axis, exerting pressure on the container and forcing it to move down as well. When moving the container, the bottom of the container will exit the center tube. The metal foil will be torn along the contour of the outer surface of the bottom of the container: the part of the foil soldered to the end of the central tube will remain on the end of the tube, and the part of the foil soldered to the bottom surface of the bottom of the container will remain on the surface of the container. With further movement, the lower part of the container with holes will exit the coverage area by the central tube, and the volumes of the container and the bottle will be combined. In order for the dry substance to fall into the liquid contained in the bottle, it is sufficient to extend the container to half its height or more. For best dissolution, the bottle must be turned upside down several times.

The prepared solution is still isolated from the external environment. To use the prepared solution, screw the case together with the screw stem from the neck of the bottle. The solution is poured through the open neck of the bottle.

The Pint cap for liquid and dry substances can be made of polymeric materials used for the manufacture of caps and bottles for PET, and using a similar technology.
