Description

 The invention relates to products for packaging, storage and consumption of liquid products, such as sparkling water, beer and other canned drinks.

The following analogues of the invention are known:
- a container with an easily opening end wall, MKI B 65 D 41/32, USA, patent 4126244, publication 1978, November 21;
- easy-opening can and method of opening it, MKI B 65 D 41/32, USA, patent 4136797, publication 1979, January 30;
- a hygienic neck for drinking liquid from a can having a tear-off tab, MKI B 65 D 41/32, USA, patent 4114778, publication 1978, September 19.

 The disadvantage of all known analog products is the lack of compliance with the hygienic conditions of consumption of the product stored in the products.

 The presence of a developed surface of the end cover of the container of the can, limited by a sufficiently high cylindrical peripheral edge, the devices for forming holes in it placed on the end cover create conditions for contamination of the end part of the container during transportation, storage, especially at trade enterprises and in everyday life. In addition, the consumption of a drink from one container due to the lack of a container that complements the container does not exclude the possibility of transmission of infectious diseases.

 Of the above-mentioned inventions-analogues, the latter is accepted by the authors as a prototype (US patent 4114778), the closest in terms of the combination of features and the goal solved by the invention.

Similar symptoms:
- bank (in the prototype) - container - a generic term;
- housing (in the prototype) - housing with an end wall;
- top wall (in the prototype) - housing cover;
- a hole tightly closed with a tear-off tongue (in the prototype) is an easily open part of the container;
- an element for opening a hole (in the prototype) - a device for forming a hole.

 The analogue adopted for the prototype is characterized by all of the above disadvantages and the goal of ensuring hygiene conditions when consuming a drink is not achieved. For example, when opening the container, a partial ejection of the drink onto the lid due to the accidental inclination of the container or from the internal pressure of the carbonated drink, increased pressure from heating or shaking during transportation will necessarily lead to its contact with dirt accumulated on the lid, especially at the location of the opening opening element . Removing the dirt accumulated on the lid is possible only by pre-flushing the lid, which is usually not possible under the conditions of consumption of the drink.

 All of the above reasons hinder the receipt of the required technical result.

 The aim of the invention is the provision of hygienic conditions for the consumption of a drink from a container.

 This goal is achieved by the fact that the device for forming a hole in an easily openable part of the container is placed on the end wall of the cap covering the upper end part of the container, and the easily openable part of the container is divided into easily bent elements.

 In the paragraph above, a set of distinctive features from the prototype of the signs, providing the desired result.

 These features are introduced in the characterizing part of the first independent claim.

The features characterizing the invention in specific forms of execution include special cases of execution:
- a cap covering the end part of the container — the cap is made, for example, of elastic polymer material, is made with a corrugated end wall, the cap is made in the form of a disposable glass covering the container body;
- devices for forming holes located on the end wall of the cap and made in various forms (described in the dependent claims and in graphic materials);
- the implementation of the easily openable part of the container, divided into easily bendable elements.

 The present invention is applicable to any type of containers used to store carbonated drinks without changing the manufacturing technology of the body, lid (except for removing the lever device for opening the hole), without changing the packaging technology of the product.

However, in addition to achieving the goal - to ensure hygienic conditions for consumption of the drink, the proposed invention allows to obtain the following positive results:
- removal of the lever device from the container lid and the use of a more compact pressure device allows to reduce the diameter of the flat case lid, which will reduce its thickness by reducing bending moment from the influence of internal pressure and, as a result, will save material consumption (cost); in addition, the possibility of reducing the diameter of the lid creates great convenience when consuming a drink and allows you to place the hole in the center of the lid, and not in the peripheral part of it, which will simplify the technology of its manufacture, will eliminate the orientation systems necessary in the manufacture of the lid with an asymmetric hole arrangement;
- for the same reason (removal of the device), you can reduce the height of the peripheral edges of the housing and the lid of the container, which will also reduce the consumption of material (costs);
- the presence of a cap on the top of the container eliminates the unpleasant consequences of an accidental discharge of the drink.

 The invention described above provides hygienic conditions for the consumption of a drink from a container, that is, the required technical result is obtained.

 The same technical result is achieved in essentially the same way by the second invention (option), which is part of the group of two inventions proposed in this application.

 The prototype for the second invention is chosen the same as for the first, with the same disadvantages that do not allow to obtain the desired technical result, therefore, is not described a second time.

 The essence of the second invention lies in the fact that the device for forming a hole in the easily openable part of the container is placed on the end wall of the cap covering the top of the container wall, made together with its body and with the easily openable part placed on it, divided into easily bendable elements, and the lid closing the container after filling it with the product is transformed into the bottom of the container.

 In the paragraph above, a set of distinctive features from the prototype of the signs, providing the desired result. These features are introduced in the characterizing part of the second independent claim.

Ensuring the achievement of the same technical result described in the first invention, the second invention due to some changes in the manufacturing technology of the container body, made in conjunction with the end wall, allows you to further obtain the following positive results:
- removing the cylindrical peripheral edge of the container body from the drink consumption zone and replacing it with an oval pairing of the body wall with the end wall creates great convenience in the consumption of the drink and further facilitates the ability to remove contamination accidentally on the end wall;
- the implementation of the upper end wall together with the container body, for example, by stamping, allows you to get any shape of the neck with a smooth decrease in its diameter to the area of consumption of the drink, which will also improve the conditions for its consumption from the container;
- the end wall that closes the container after filling it with the product and transforms to the bottom (in a static position) can be made concave, reinforced by annular wave-shaped ribs in order to reduce its thickness (manufacturing costs), can be attached to the body wall without first crimping the body in diameter, which will simplify the manufacturing technology of the container.

 In FIG. 1 shows a container (longitudinal section) for storing liquid products, comprising a housing 1 with an end wall 2, a housing cover 3, an easily opened part of the container 4, a cap 5 with its end wall 6 and with a device 7 placed thereon for forming an opening in an easily opened parts of the container.

 On Fig shows a container lid (section), in which the easily openable part is divided into easily bendable elements - disks 31, 32 with sealing contour contours, for example, with polymeric material 30 (the material layer is shown by the dot-dash line). The same embodiment of the easily openable part of the container is shown in FIGS. 4, 19, 21 and 22.

 In Fig.17 shows a view along arrow B (see Fig.16).

 On Fig shows a container (longitudinal section), where the easily open part of the lid of the container is blocked by one easily bent element 31 (option) with sealing similar to Fig; on Fig, in addition, shows an embodiment of the neck 33 of the container with a reduced diameter of the lid 3 of the container and with the connection of the neck to the container body with an additional connection 34; shows the embodiment of the sleeve 13 without internal longitudinal ribs (in contrast to the variant shown in figure 4).

 Structural solutions for placing devices for opening holes in the end wall of the container, made in conjunction with its body, and related to the second invention (option) are presented in Fig.19-22.

 On Fig shows a container for storing liquid products (longitudinal section), comprising a housing 1, an end wall 2, made in conjunction with the housing in the form of a neck of the container with compression radii along the generatrix of the wall from 3 to 10 mm; an easily openable hole 4 is placed on the end wall; on the cap 5 there is a device 7 for opening a hole in the container, and the lid of the container 3 is transformed into the bottom of the container.

 In FIG. 20 shows a variant of placement of a cap made in the form of a glass 8 and covering the end wall of the container, made in conjunction with the body; lid-bottom 3 is made concave.

 On Fig shows a container (longitudinal section) with an embodiment of the end wall 2 of the container, made in conjunction with the housing in the form of an elongated neck, and with an embodiment of the lid-bottom 3, made in size of the diameter of the housing without compression.

 In FIG. 22 shows a container (longitudinal section), an embodiment of the end wall 2 together with the housing using the connecting element 34.

 A device for opening a hole in the container, for example, Fig. 1, placed on the end wall of the cap covering the upper end part of the container, works from the effort of a hand applied to it through the end wall of the cap in order to move the device (push-protrusion) until it breaks easily open parts along the lines of weakening and bending of its individual elements into the container.

 In Fig. 1, the push-protrusion 7 is integral with the end wall 6 of the cap 5. The end wall is elastic, which does not interfere with the operation of the push device. When reducing the diameter of the lid of the container, and therefore the diameter of the end wall of the cap (for example, FIGS. 4 and 18) to maintain elasticity, it is made with corrugations.

 In Fig.2, the push-protrusion 7 is made integral with the end wall of the cap-cup 8 and when pressed by a hand, it moves together with the cap, destroying the easily openable part of the container, which can be made, as shown, for example, in Fig.10- thirteen. The cup-cap 8 is held on the container body, for example, by means of elastic annular protrusions 9 made on the wall of the glass and covering the container body. Fixing the cap-cup on the container body can be performed in another way, for example, using easily removable adhesive tape with a hygienically clean gasket covering the outer edge of the glass wall and simultaneously glued to the container body around the circumference.

 The pressing protrusion device 12 (Fig. 4) is provided with a sleeve 13, which, after the device is triggered, is fixed in the formed hole using elastic ring protrusions 15, and rests on the edge of the formed hole with the flange 14. The sleeve is provided with windows 16 in its side wall, providing a complete discharge of fluid from the container. The sleeve may be provided with stiffening ribs 17. Sleeve 13, being an integral part of the pushing device-protrusion, after its operation, fixes easily bent elements in the position bent inward of the container, preventing their accidental return to the hole zone under the influence of a liquid stream (especially for non-metallic applications covers). In addition, a jet of fluid consumed from the container is formed using the sleeve. The internal stiffening ribs 17 at the same time form a filter that prevents the accidental tear-off element of the lid from entering the liquid stream when it is bent into the container.

 The easy-to-open part of the container can be made according to any variant of those shown in FIGS. 10-16. In any case, the pressure protruding device initially acts on the central element (central part) of the easily openable part of the container. For example, in the easy-to-open portion of FIG. 10, the element 18 initially opens. The smaller perimeter of the line of weakening of the specified element, in comparison with the perimeter of the entire hole, will require less effort to tear off the element 18. With the further action of the pushing protrusion on the ring element 19 around the perimeter of the previously torn element 18 to reduce the required force the separation of the ring will contribute to the lack of internal pressure in the container and the formation of bending moment in the annular element 19.

 The above factors positively characterize the proposed design of the device.

 For the easy-to-open part of the container shown in Fig. 12, it is preferable to use a push-protrusion device made in the form of a cone (Fig. 6) or a truncated cone (Fig. 7), for a more differentiated effect of the force when the ring elements are made in the form spirals.

 All the structural solutions described above for the implementation of the device for opening the holes apply to the second invention (option) - (Fig. 19-22). The difference of the second variant of the invention is that the cap with the device for opening the opening in the container located on it is located on the end wall of the container, made together with its body and in which there is an easily openable part, divided into easily bendable elements, and a lid covering the container after filling it with the product, it is transformed into the bottom of the container. This solution allows you to exclude the end edge of the container lid from the area of consumption of the drink from the container, which will further improve the hygienic conditions of its consumption, in addition, allows you to make the neck of the container with streamlined forms, which creates additional convenience when consuming a drink from the container (Fig.19-22) .

 Feasibility from the use of the invention is to ensure hygienic conditions for consumption of products stored in the container, in the additional convenience of their consumption by reducing the diameter of the neck of the container and giving it a streamlined shape, in addition, the use of the invention will reduce the cost of manufacturing the container by reducing the thickness container lids when reducing its diameter, in the manufacture of its concave shape and reinforcing it with annular protrusions.
