Description

The utility model relates to capping equipment, in particular to devices for manual capping of containers such as glass jars with carvings, and can be used mainly for home canning of food products.

A device for capping cans is known, comprising a lid and a sealing ring according to RU patent for invention No. 1799352, IPC B67B 3/24? publication date 02/28/1993

Disadvantage: the complexity of the evacuation mechanism.

A device is known according to RU patent for utility model 37709, IPC B67B 3/24, publication date 05/10/2004. This device has a collar and an additional collar made to it coaxially, between which a gasket is installed.

The disadvantages of the known device include the need to use complex and bulky vacuuming devices that create a sealed volume around the neck of the jar with a lid with an o-ring placed on it. In addition, it is difficult to open the lid due to the need for significant efforts, in particular, to the o-ring. Some o-rings provide an element that protrudes beyond the lid contour, pulling it out from under the lid and stretching the o-ring results in depressurization of the can and equalization of air pressures outside and inside the can under the lid.

Known lid for sealing containers such as glass jars according to the patent for invention 2339569, IPC BV 3/4, publication date 11/27/2008

A device for vacuum sealing containers such as glass jars (Fig. 1 ... 10) contains a cover 1, a poppet valve 2 with a stem 6 and an o-ring 3 (Fig. 1). In the middle of the upper part of the lid 1, a recess 4 is made, with a saddle 11 located in the center, raised above the bottom of the recess 4, and an opening 5 (Fig. 1). The stem 6 of the poppet valve 2 is placed in the hole 5. Between the surface of the hole 5 and the surface of the stem 6, a gap is provided for air to pass by the appropriate choice of the diameter of the hole 5 and the outer diameter of the stem 6. The upper part of the cover 1 is made spherical with the convex side directed upward from the bottom covers 1. (Fig. 1, 2).

The upper part of the poppet valve 2 is made spherical in shape 10 and its edges are located beyond the edges of the seat 11 of the cover 1, made inside a conical shape, and raised above the bottom of the recess 4 in the middle part (Fig. 1, 6).

The cap 1 contains an outer ring 12 and an inner ring 13 on the lower part of the cap 1 (Fig. 1. On the outer ring 12 there is an end face 14.

Directly at the end face 14 on the inner surface 15 of the outer ring 12, hooks 16 are made for interacting with the can thread (cans and threads are not shown).

At least 3 hooks must be made 16. The hooks 16 are made at an installation angle ϕ to the end 14. The optimum installation angle ϕ of the hooks 16 is from 5 to 15 ° (Fig. 5).

The appearance of the hooks 16 is shown in FIG. 10.

About each hook 16 in the outer ring 12 can be made of the slot 17.

On the outer surface 18 of the outer ring 12, alternating longitudinal ledges 19 of a semi-cylindrical shape can be made (FIGS. 1 and 8). Alternating longitudinal ledges 19 of a semi-cylindrical shape can be made in pairs against the hooks 16 (Fig. 8).

The poppet valve 2 with a stem 6 is made in one piece cast design, ensuring constant shape at high temperatures, thereby improving the quality of the closure of the lid during repeated use. (Fig. 1) The poppet valve 2 with a stem 6 is made of PVC compound.

The outer and inner sides of the recess 4 can be articulated with the middle part of the lid 1 through fillets, and the outer and inner edges of the bottom of the recess 4 can be rounded. This embodiment of the recess 4 and the lid 1 reduces the concentration of mechanical stresses at the points of transition from the bottom to the walls of the recess 4 and from the walls of the recess 4 to the middle part of the lid 1. The recess 4 is made in the form corresponding to the external shape of the nozzle of the vacuum device inserted into the recess 4 before evacuation. The recess 4, for example, can be made cylindrical using a cylindrical fitting of a vacuum device. As a vacuum device can be used a pump with a cylindrical lower part with a diameter corresponding to the diameter of the recess 4. (Fig. 1, 2)

On the inner part of the bottom of the recess 4 around the hole 5 there is a saddle 11 with a recess 7 of an internal conical shape (Fig. 1, 2). A protrusion 8 is made on the lower part of the stem 6 to prevent the poppet valve 2 from falling out of the hole 5 when the populated valve 2 is pumped out with evacuated air when evacuated by a vacuum device, for example, a reciprocating pump (Fig. 1). On the lower outer part of the recess 4 around the hole 5, alternating stops 9 are made in the amount of 6 pieces (Fig. 2), providing gaps between the lower outer part of the recess 4 and the protrusion 8 of the poppet valve 2 (Fig. 1, 4), that is, the valve is securely fixed in the cover nest. The outer side of the poppet valve 2 adjacent to the surface of the recess 7, given a spherical shape (Fig. 1 and 8). The lower part of the stem 6 of the poppet valve 2 is made conical in shape (Fig. 1). This embodiment facilitates the placement of the stem 6 of the valve 2 in the hole 5 when assembling the device. O-ring 3 is located between the outer and inner rings 12 and 13 on the lower part of the cover 1 (Fig. 1). The cover 1 may be made of metal, glass or plastic. The cover 1 has a round shape and means for contacting the thread. The poppet valve 2 is made of PVC compound. O-ring 3 is made of rubber or PVC compound.

The lid is installed in relation to the neck of the jar centered, not shifting to the edge of the jar. The height of the lid socket is made in the size of 7 ... 10 mm, due to which the pump is installed in the socket tightly and strictly vertically, and does not fall on its side. In order not to warp and give less shrinkage when heated, the thickness of the sealing ring 3 is made in the size of 1.5 ... 2.0 mm. (Fig. 1). Standard material requirements - safe for human health. In addition, they must repeatedly withstand sterilization processes of the device before use.

DEVICE OPERATION

The device operates as follows. Place the device (Fig. 1) on the neck of the container, engage the hooks 16 before contact with the thread of the can. The device is rotated using longitudinal ledges 19 (FIG. 8) until the hooks 16 are fully engaged with the thread of the can (thread and can are not shown). Then, in the recess 4 of the lid 1 with a poppet valve 2, a nozzle of the vacuum device (not shown) is inserted and the device is pressed to the neck of the container through the sealing ring 3. The device is pressed through the sealing ring 3 by turning the device using longitudinal ledges 19 (Fig. 1 and 8) until the gears 16 are fully engaged with the can threads.

When creating a vacuum in the nozzle of the evacuating device, the poppet valve 2 will let air from the container into the recess 4. When the necessary vacuum in the container is reached, the evacuating device creates an air pressure above the recess 4 equal to the air pressure around the container. In this case, the poppet valve 2 will be pressed to the bottom of the recess 4, and the cover 1 through the sealing ring 3 will be pressed to the neck of the container. Pressing the poppet valve 2 to the seat 11 and the cover 1 through the o-ring 3 to the container will ensure the tightness of the container. To depressurize the container, bend the edge of the poppet valve 2 to let air into the container through the hole 5. After depressurization of the container, the device is removed from the neck of the container. To unscrew the lid 1 also use the longitudinal ledges 19 (Fig. 1).

In the process of evacuation, the sealing ring 3 is pressed against the cover 1 so tightly that it subsequently makes it difficult to remove the sealing ring 3 from the cover 1 to sterilize the device before reuse.

The lid according to the patent of the Russian Federation for utility model No. 164829 can also be used for cans with thread. The instructions for the specified lids provide for the use of lids on jars with threads. When using the proposed lid on cans with thread, the best evacuation effect is achieved, since the end face of the can is polished and narrow, which ensures the best fit of the lid.

The inventive device meets the criteria of patentability "novelty", and can be implemented industrially in mass production.

A prototype device has been manufactured and tested. The device can be used repeatedly (at least 200 times). The duration of operation is determined by the elastic properties of the materials from which the poppet valve 2 and the sealing ring 3 are made.

Application of the utility model allowed:

- expand the range of products (lids for cans) and ensure its use for cans with thread,

- improve the tightness of the lid,

- to simplify the sealing of the cans for which these lids are intended.
