Description

Field of application

The utility model refers to a capsule for storing a product intended for mixing is a liquid product in a plastic bottle, which is used in the food industry for the preparation of beverages immediately before use. The capsule can be used in other areas requiring mixing of active substances and solutions, such as pharmacy and agriculture.

BACKGROUND OF THE INVENTION

A capsule containing a liquid or powdered product for mixing in a container is a liquid product (1). The capsule includes a storage tank for the product, which has an opening in its lower part for the passage of the product from the capsule into the container is the liquid product. The opening may be a diameter equal to the diameter of the tank, or it may be a smaller diameter forming the neck of a bottle.

The wall of the lower part of the tank is covered by a cylindrical body provided with means for axial sliding between open and closed position. A hinged valve is connected to the cylindrical body, which has a line of rupture at its periphery, formed by reducing the thickness of the valve in this area. The valve is made by molding a plastic material and serves to open the lower opening of the tank by tearing it when moving to the peripheral end of the lower part of the tank.

The capsule has a cylindrical part which covers the lower part of the tank and the cylindrical body. The cylindrical part is equipped with an internal thread for winding to the neck of the container. The cylindrical part and the tank are made as a monolithic body.

The tank may have an opening in its upper part, the cap is closed.

Before use, the capsule is wound on the neck of the container, which causes the cylindrical body to slide so that the lower part of the tank passes through the cylindrical body, tearing the valve in the line of rupture, as a result of which the product passes from the capsule into the container. The hinged connection of the valve to the cylindrical body prevents the valve from entering the container. The container and capsule can be shaken to better mix the two products, after which the mixture can be used by removing the capsule from the neck of the container.

Technical essence of the utility model

The purpose of the utility model is to offer a capsule for storing a product intended for mixing a liquid product in a plastic bottle, which is a simple construction.

This object is achieved by a capsule for storing a product for dissolution in a plastic bottle, which includes a tank for storing the product, the inlet of which is closed in its upper part by a cap, and an outlet is formed at its bottom. The capsule also has a cylindrical part, an internal thread is provided for connection to the neck of the bottle and a valve for releasing the product from the tank is formed on its periphery line of rupture and connecting segment. The capsule is characterized by the fact that the inlet cap is made of elastic material, and the valve for releasing the product from the tank is an elastic membrane. On the outer wall of the bottom, parallel to the outlet, a channel is formed, to which the elastic membrane is fixedly connected. Between the wall of the outlet and the inner wall of the channel in the section corresponding to the line of rupture of the membrane, a cutting element is formed, and the cylindrical part is the internal thread for connection to the neck of the bottle is formed as a continuation of the surrounding walls of the tank.

A sleeve can be formed to the outlet, the channel being located in the lower wall of the sleeve.

The advantage of the capsule is its simplified construction: it is made of three elements - a monolithic body (tank and cylindrical part), a cap and an elastic membrane. The materials for construction comply with the standards for contact with food, pharmaceuticals and agricultural products.

Examples of implementation of the utility model

The capsule for storing a product to be mixed is a liquid product in a plastic bottle according to FIG. 1, consisting of a tank 1 is a volume V for accommodating the product, the inlet of which 2 in its upper part is closed is a cap 3 made of elastic material. An outlet 5 is formed on the bottom 4 of the tank 1. The surrounding walls of the tank 1 pass into a cylindrical part 6, an internal thread 7 is provided, complying with the standards of the plastic bottles.

A channel 8 (Fig. 2) is formed on the outer wall of the bottom 4, parallel to the outlet opening, to which the elastic membrane 9 is fixedly connected, for example by casting technology. This method ensures reliable adhesion between the two materials (plastic and elastomer). The membrane 9 has at its periphery a rupture line 10 and a connecting segment 11 (Fig. 3). The rupture line is formed by reducing the thickness of the membrane 9, and the connecting segment 11 - by increasing the thickness.

Between the wall of the outlet 5 and the inner wall 12 of the channel 8, in the section corresponding to the line of rupture 10 of the membrane 9, a cutting element 13 is formed (Fig. 2).

The tank 1 together is the cylindrical part 6 are made of plastic as a monolithic body.

In another embodiment, not shown in the figures, a sleeve can be formed to the outlet 5, in the lower wall of which the channel 8 is made.

The product intended for dissolution in a plastic bottle is placed in the tank 1, after which the capsule is closed with the cap 3.

Before use, the capsule is screwed onto the neck of the plastic bottle by means of the internal thread 7 of the cylindrical part 6, which thread meets the different standards and sizes of necks for plastic bottles.

After screwing the capsule, the bottle is squeezed by hand, thus creating a pressure Pb (Fig. 4), which inflates the membrane 9 and presses it to the cutting element 13 in the line of rupture 10. Due to the elasticity of the membrane 9 and the cap 3 the volume V of the tank is retained. Pressing the cutting element 13 to the tear line 10 of the membrane 9 causes it to be cut.

When the bottle is released, the pressure (Pb) is removed, the outlet 5 is opened, which allows the soluble product contained in the tank 1 to pass into the liquid contained in the bottle.

The connecting segment 11 remains connected to the channel 8 and the membrane 9 does not fall into the bottle. After shaking the liquid in the bottle, the capsule is removed and the contents of the bottle can be consumed.

The advantage of the capsule is its simple construction: it is made of three elements - a monolithic body (tank and cylindrical part), a cap and an elastic membrane. The capsule is easy to use by users - wrapping the capsule on the neck of the bottle, squeezing the bottle, shaking and the solution is ready for use.
