Description

The claimed technical solution relates to household appliances, namely to devices for manually capping glass jars with metal lids, which are used at home when performing work on canning food (for example, vegetables, fruits, berries, etc.) in glass jars that are closed metal lids.

The closest technical solution (prototype) is a device for manual capping of glass jars (RF Patent No. 8694, B67B 3/02, publ. at the edge it is conically profiled inside the cup, the sealing mechanism in contact with the body consists of a clamping force generation unit, including two handles with supporting elements at the ends, a bushing having an end with an annular groove in the lower part directed towards the conically directed section of the cup wall, there is an element crimping of the metal cover, made in the form of an elastic ring made of a twisted spring, placed on the inner surface of the wall of the glass at the boundary of the transition of the wall into a conically directed section, at least three pushers are placed symmetrically relative to the longitudinal axis of the glass, one end of which is placed in the corner formed by the bottom part glass and its wall, and the other end of the sense ately pressed to the annular groove on the end of the sleeve by means of a plate-shaped washer, turned with its bottom part up, spring-loaded from the side of the conically profiled section of the cup wall by an elastic ring made of a twisted spring, there is a cylindrical element with rectangular holes in the side surface, the lower part of which is rigidly fastened to the outer surface of the bottom part of the glass coaxially with its central hole, there is also an axis installed in the wall of the cylindrical element at its top normally to the rectangular holes, the handles are fixed on the axis mirror relative to each other with the possibility of inserting the handle eccentrics into the rectangular holes of the cylindrical element.

Disadvantages of the prototype: reduced reliability (quality) of capping a glass jar with a metal lid due to:

- poor sliding of the bushing in the element of a cylindrical shape, because the metal sleeve moves inside the cap without the use of lubricant between them;

- increased bushing wear;

- production of a sleeve and a cylindrical element from metal, which forces the user to exert increased efforts on the handles, and this reduces the pressing force of the metal lid during capping of the glass jar;

- reduced stroke of the handles, because supporting (pressure) elements are made with a sharp increase in the eccentricity of the working surface relative to the axis;

- the presence of a cap that reduces the stroke of the handles of the device;

- the presence of an annular cutout (step) in the washer, which reduces the contact area with the metal cover.

The technical problem solved by the creation of a new device is that food products (vegetables, fruits, berries, etc.) sealed at home in glass jars often have a short shelf life due to a violation of the tightness of metal lids due to the poor quality of closure glass jars with metal lids, which is due to the imperfection of the design of hand-held devices used by consumers in everyday life.

The technical result of the claimed utility model is the creation of an improved device with a new set of structural elements, which makes it possible to increase the reliability (quality) of manual capping of glass jars with metal lids.

The technical result is achieved by the fact that the device for manual capping of glass jars with metal lids contains a body in the form of a glass, with its bottom part facing upwards with a central hole, where the wall section of the glass at the edge is conically profiled inside the glass, the sealing mechanism in contact with the body consists of a clamping force generation unit , which includes two handles with support elements at the ends, a sleeve having an end with an annular groove in the lower part directed towards the conically directed section of the glass wall, there is a crimping element of the metal cover, made in the form of an elastic ring made of a twisted spring, placed on the inner surface of the wall cup at the boundary of the transition of the wall into a conically directed section, at least three pushers are placed symmetrically with respect to the longitudinal axis of the cup, one end of which is placed in the corner formed by the bottom part of the cup and its wall, and the other end of the pushers is pressed against the annular groove at the end in bushings by means of a plate-shaped washer, with its bottom part facing upwards, spring-loaded from the side of the conically profiled section of the cup wall by an elastic ring made of a twisted spring, there is a cylindrical element with rectangular holes in the side surface, the lower part of which is rigidly fastened to the outer surface of the bottom part of the cup coaxially the central hole, there is also an axis installed in the wall of the cylindrical element at its top normal to the rectangular holes, the handles are fixed on the axis mirror relative to each other with the possibility of inserting the eccentrics of the handles into the rectangular holes of the cylindrical element, the washer is made with a recess, the cylindrical element made in the form of a branch pipe, the rectangular holes of which are made in the form of open slots at its top, inside which there is a sleeve with the possibility of vertical movement, made of plastic and made with a blind inner open m hole, in the upper end of which the lower step of the steel upper thrust bearing is placed, located above the bushing, on the lower groove of which there is a steel ring, the upper surface of which is in contact with the bushing end formed by its lower groove.

In this case, the pushers are made with corrugations directed upwards.

At the same time, handles made of plastic with hollow inner surfaces have external corrugations in the lower parts.

At the same time, the supporting elements at the ends of the handles are made with a smooth increase in the eccentricity of the working surface relative to the axis.

New essential distinguishing features of the proposed technical solution are the following features:

the washer is made with a recess;

element of cylindrical shape is made in the form of a branch pipe;

rectangular openings of the branch pipe are made in the form of open slots at its top;

inside the pipe there is a sleeve with the possibility of vertical movement, made of plastic and made with a blind inner hole;

in the upper part of the hole of the sleeve is placed the lower stage of the steel upper thrust bearing located above the sleeve;

on the lower groove of the bushing there is a steel ring, the upper surface of which is in contact with the end face of the bushing formed by its lower groove.

The combination of new essential distinguishing features, along with the features known from the prior art, is sufficient to solve the specified technical problem and obtain the technical result provided by the utility model - the creation of an improved device with a new set of structural elements that makes it possible to increase the reliability (quality) of manual capping of glass jars with metal lids.

The device for manual capping of glass jars with metal lids contains a body 1 in the form of a dish-shaped glass with a central hole 2 turned upside down.

The cylindrical element - pipe 5 - is rigidly attached to the outer surface of the bottom part of the plate-shaped cup.

In the inner lower part of the body 1 there is a plate-shaped washer 6 with the bottom part directed upwards. The plate-shaped washer 6 has a recess 7 designed to accommodate the end of a metal lid in it when capping a glass jar with its contents. The recess 7 is molded according to the diameter of the plate-shaped washer 6.

The branch pipe 5 is made with two open vertical slots 8, radially located opposite each other. The slots 8 of the nozzle 5 start from the upper surface of the nozzle 5 for a length that is, for example, 9/10 of the length of the nozzle 5.

In the branch pipe 5 there is a plastic sleeve 9 of a cylindrical shape with the possibility of its movement along the vertical axis of the couple 5. The sleeve 9 has a blind inner hole 10 cut from the upper surface of the sleeve 9 to a length that is, for example, 7/8 of the height of the branch pipe.

Above the sleeve 9 there is a steel thrust bearing 11, made with a lower step 12, which is located in the blind inner hole 10 of the bushing 9. The diameter of the lower step 12 of the steel thrust bearing 11 corresponds to the diameter of the blind inner hole 10 of the bushing 9.

The bushing 9 has an outer annular groove 13 at its lower end, forming a lower end (not shown in the figure), against which the upper surface (not shown in the figure) of the lower ring 14, made of steel, abuts. The ring 14 is mounted on the lower groove 13 of the sleeve 9.

At the end of the lower part of the sleeve 9 there is a blind (technological) hole 15 having a depth of, for example, 2-3 mm. The blind (technological) hole 15 is made coaxial with the central axis of the cylindrical sleeve 9.

Between the body 1, made in the form of a dish-shaped cup, and the washer 6, there are three pushers 16, the inner end ends of which are pressed against the annular groove 13 of the sleeve 9 by means of a washer 6, spring-loaded from the side of the conically directed portion of the cup wall by an elastic ring 17 of a twisted spring, and the opposite ends of the three pushers 16 are placed in the corner formed by the bottom of the glass and its wall 3. The elastic ring 17 of the twisted spring is installed to move in the vertical direction. Pushers 16 are made with stiffening ribs 18 directed upwards.

Three pushers 16, located around the circumference at an equal distance from each other relative to the axis of the housing 1, transmit the force from the sleeve 9 with the upper thrust bearing 12 and the lower ring 14 to the movable plate 6 washer.

An axle 19 is pressed into the opening of the branch pipe 5, located perpendicular to the slots 8, on which handles 20, 21 with support (pressure) elements 22, 23 at the ends are mirrored relative to each other. The support (pressure) elements 22, 23 at the ends of the handles 20, 21 are made with a gradual increase in the eccentricity of the working surface relative to the axis 19. The handles 20, 21 are made to move in opposite directions (by 180°) in the vertical slots 8 of the pipe 5. Handles 20 , 21 made of plastic are made hollow inside. The lower parts of the handles 20, 21 are made with corrugations 24 for a length that is 1/3 of the length of the handles 20, 21.

The device works as follows. To carry out manual capping of a glass jar with contents for preservation, a metal lid is installed on the neck of the glass jar, and then the proposed device is placed on it so that the upper part of the metal lid is covered by a recess 7 of the plate-shaped washer 6.

The user then grasps the two handles 20, 21 of the device with both hands and applies perpendicular pushing forces to them, so that the handles 20, 21 make a downward circular motion of 90° each. When this happens, the position of the support (pressure) elements 22, 23 at the ends of the handles 20, 21 relative to the sleeve 9 changes, imparting translational movement to it.

Through the end of the lower ring 14 of the bushing 9, three pushers 16 press on the plate-shaped washer 6, pressing it against the surface of the metal cover (not shown in the figure). At the same time, the opposite ends of the three pushers 16, placed in the corner formed by the bottom of the glass and its wall 3, tell the body 1 upward movement.

The vertical movement upwards of the body 1 leads to the movement of the elastic ring 17 from the coiled spring to the conically profiled section 4 of the cup wall. The result is a compression of the elastic ring 17 of the coiled spring and, accordingly, a decrease in its diameter in the horizontal plane. Reducing the diameter of the elastic ring 17 of the twisted spring provides its force effect on the metal lid along its entire perimeter, leading to the sealing of the glass jar with its contents. When the user removes the force from the handles 20, 21, they return to their original position under the influence of the spring action of the elastic ring 17 of the coiled spring on the washer 6 of the plate shape. The device is then removed from the sealed metal lid of the glass jar.

Unlike the prototype, where the quality of manual capping of glass jars with metal lids is reduced, due to the fact that in the clamping force creation unit of the sealing mechanism there is poor sliding of the sleeve in the cylindrical element (the sleeve and the cylindrical element - the cap are made of metal without lubrication between them) , in the proposed technical solution, the sleeve made of plastic ensures the ease of sliding of the sleeve inside the pipe, and the presence of the upper bearing of the sleeve and the lower ring on the lower groove of the sleeve, made of metal, reduces wear on the end parts of the sleeve, ensuring the reliability of the device, and consequently - improving the quality of capping glass jars with metal lids. The ease of sliding of the plastic sleeve inside the nozzle increases the performance of the proposed device.

Unlike the prototype, where the manufacture of a metal sleeve and a cylindrical element contributes to the user's application of increased efforts on the handles, which reduces the compression force of the metal lid during capping of the glass jar, in the proposed technical solution, the manufacture of the sleeve from plastic and the pipe from metal reduces the force on the handles of the sealing mechanism, which, with the same pressing force as the prototype of the metal cover of the glass jar during capping, provides an improved quality of capping food products in glass jars using the proposed technical solution.

In the proposed technical solution, the reduction of the user's efforts on the handles at the time of crimping the metal cover is provided due to the anti-friction properties (friction reduction) of the plastic sleeve.

Unlike the prototype, where the stroke of the handles is reduced due to the fact that the supporting (pressure) elements are made with a sharp increase in the eccentricity of the working surface relative to the axis, in the proposed technical solution, the supporting (pressure) elements are made with a smooth increase in the eccentricity of the working surface relative to the axis, which reduces the force on the handles, while increasing the stroke of the handles, i.e. with the same pressing force as the prototype of the metal lid of the glass jar during capping, the proposed technical solution provides an improved quality of capping food products.

Unlike the prototype, where a cap is used as the upper cylindrical element, the proposed technical solution uses a branch pipe as the upper cylindrical element, which makes it possible to increase the stroke of the device handles and, accordingly, qualitatively seal the glass jar with a metal lid.

Unlike the prototype, where the washer for accommodating the end of the metal lid during capping has a central groove (step) - an annular cutout with a reduced area of the end surface, in the proposed technical solution in the washer for accommodating the end of the metal lid, a recess is made, shaped according to the shape of the metal lid ( with an increased end surface area), which makes it possible to more securely fix the metal lid on the glass jar (to carry out the basing of the device on the plane of the washer), providing an increased quality of manual capping.

Unlike the prototype, the proposed technical solution is characterized by a cheaper device due to reduced metal consumption: the sleeve is made with a blind hole; plastic is used as the sleeve material; the inside of the handles is hollow; the lower part of the sleeve is made with a blind (technological hole). The implementation of corrugations on the handles creates convenience for the user (ergonomics), because. does not cause discomfort when sealing a glass jar with a metal lid. In the process of pressing the handles, the user's hands do not slip along the surfaces of the handles to the bottom, which increases the productivity of work using the proposed device.

The proposed technical solution helps to reduce metal consumption and simplifies the manufacture of the device.

All components of the claimed technical solution are interconnected by assembly operations, i.e. are in functional and constructive unity.

Implementation of the proposed utility model allows solving the claimed technical problem and ensuring the achievement of the claimed technical result.

The proposed technical solution, which has a constructive unity, implements a common functional purpose (functional unity).

The prior art has not found an analogue characterized by features identical to all the essential features of the claimed utility model.

The applicant tested the proposed device, which confirmed its purpose, feasibility and performance, in this regard, the claimed utility model meets the condition of patentability "industrial applicability".
