BG98277U - Protection device for covering fairly small vessels - Google Patents

Abstract

The protection device is aesthetically designed and can be applied for vessels which are not designed to be airtight or the latter is lost after their opening. It prevents any spilling of the content of the vessel in transportation, due to external effect or to negligence. The device has an arbitrary shape and lower conical part of impermeable elastic material (1) mounted to a fairly small vessel (2) e.g. standard type cups, boxes, jars, etc. for different hot and cold drinks which increases their capacity and preseves the quality and the temperature of the content by preventing any unwanted mass exchange. The heat exchange with the environment and during transportation and consumption in adverse atmospheric conditions - dust, insects and other pollutants is reduced by using a straw (3).\!

Description

The utility model relates to a protective device for hermetically sealing small vessels, such as commonly used disposable cups.

BACKGROUND OF THE INVENTION

Known packaging and non-metallic containers for containers intended for the transportation of various types of beverages and food products Sour milk, halva, juices, etc.), which prevent spillage and contamination of the contents. Such are the patents: from Bulgaria 26064 / 26.02.79, from the USSR 1212878 / 23.02.86, from the USA 4538741 / 03.09.1985, 4886184 / 12.12.1989 and 4407426 / 04.10.1983. In the above patents, the once produced caps are applicable to specifically designed vessels having well-defined aperture sizes. They serve to close the container after filling, both at the factory and immediately before sale, and have a complex construction and high cost. The latter is avoided in the patents of the USSR 1013359 / 11.05.78, US 3955699 / 11.05.1976 and 4294367 / 13.10.1981, which in turn require special equipment for sealing vessels against abuse.

Similar inventions for sealing vessels that permit consumption during transport are, for example, patents from Bulgaria 43421 A / 30.06.88, from US 4586625 / 06.05.1986 and 4421244 / 20.12.1983 and many others. They provide a place for inserting a straw, if one is not fitted in the cap, or there is a space for opening a narrow gap, or there are other devices for consumption, the caps being again with complicated construction - made only in special molds. Some of the patents are characterized by the fact that they minimize the volume when storing a certain amount of caps through improvements in the packing compaction design.

The most widely used in the sale of hot and cold drinks are disposable glasses of various shapes and sizes.

The technical nature of the utility model

The problem that arises with the use of disposable glasses is that in many cases they need to be covered or closed when transported and consumed, as the latter is unrelated to some discomfort and daily incidents of spills, contamination, minor injuries from burning. The waste of time, nerves and remedies added to nutritional losses lead to reduced use of these glasses, especially in risky situations where the consumer is in a vehicle, is driving or is in a busy place.

There is no known cap construction that closes openings of different sizes. The decision to pre-seal the cups with foil is not possible as long as the beverage is poured into the cup just before consumption.

The manufacture of caps of the above-mentioned structures for specific cup sizes is a complex process with a high cost - commensurate with that of the cups.

The utility model for solving this problem is a protective device for covering vessels with different aperture shapes: a circle, an ellipse or a convex polyhedral. The device is characterized in that it has a predominantly cone shape made of a waterproof sheet material, which, placed on the cup, encloses a closed airtight space and encloses it with a guaranteed tightness, obtained from a press joint when fixed by a pressing force according to BDS 15611 / 82 SSECD p.255-262).

The latter allows tight closure of any size smaller than that of the lower base of the cone.

The impermeable elastic sheet material may be a polymer film, tube or other having a modulus of elasticity in the range of 1 MPa to 7 GPa, a tensile strength of not less than 9 MPa and an elongation of not less than 500%. When the modulus of elasticity is increased, the peak angle of the wedge cone may increase - 10 ° - 55 ° to save the material involved.

The assembly can be reinforced in certain cases with an additional element - elastic, thread, wire, adhesive tape, etc., for example, to increase the capacity.

At the top of the cone, the fixture can be of any shape. When opening an opening, it is possible to consume the contents of the container with and without a straw.

The safety device prevents the drink from spilling into the glasses during transportation or inadvertence on the part of both the consumer and the consumer. The gadget allows consumption in any adverse environment - snow, ice, rain, wind,

dust, insects and other contaminants. It preserves the quality and temperature of the contents by reducing the mass and heat exchange with the environment of any liquid beverage Hot or cold} in standard cups, jars, jars and any other type of container, regardless of size or material, whose tightness is not foreseen at all. or is lost after opening.

Storage of the product before use is no problem because of the ability to pack tightly with the bags. Putting it on the dish, even with the straw, does not require 10 seconds.

Examples of specific implementation

The construction of the variant of Fig. 1 is in the form of a truncated cone in the general case Strap-like in the non-assembled state, Fig. angles at the lower base not greater than 90 ° and a through hole between the two bases of dimensions

SUITABLE FOR:

- placing the cup 2 with the drink inside it from to the lower, wider base with a tightness: See figures 1 and 2), and

- Stacking the top 3 with a looseness or tightness. 13

The construction of the variant of FIG. 2 is in the form of a cone 1 in the present case. Folded unassembled, FIG. 33, and FIG. 5 with a cone only in the lower portion, enclosing the vessel 2 hermetically by means of a press joint with tightness.

The fixture is placed on the cup after filling and pressed down until a press cone joint is formed with a tightness between the bag and the cup. This is accounted for by the appearance of a horizontal zone between the envelope and the edge of the cup, since the interval of permissible deformations is wide and this facilitates assembly without the risk of breaking the conical section or insufficient tightness. This is established by lifting the glass with all the contents in it, grasped by the bag. In rare cases, an additional fastener is fitted. The customer chooses whether the cover is for transport only or for consumption as appropriate with a straw 3 in the cut tip or other sections of the fixture when the shape is not conical, resulting in a direct aroma to the sense of smell or by piercing the bag when inserting the straw providing tightness around it.

To receive fluid in a supine position without the risk of choking, cut off the appropriate tip of the dispenser serving device by tilting the pouring glass of each dose, continuously controlled by light pressure. In this case, any patterns and painted shapes on the outer surface will facilitate dosing and aesthetize the passage of emulsions and suspensions;

The cone can be used instead of a funnel for fast and non-spill overflow in other vessels regardless of quantity and flow rate;

The technology of fabrication of the device is as follows: In industrial conditions, soldering or gluing 5 (Fig. 4) of article 1 occurs at a guaranteed seam density in a thermal or other conventional food way in any of the following ways:

- in the general case - welding of double foil along the contour of the desired figure without its conical base;

- for cone shapes - in the standard delivery of polyethylene coils 4, a belt is cut in length equal to the height of the triangular article 1 (Fig. 3,4) and welded linearly by cutting from the heating itself 5 below the material angle corresponding to the material. The triangles thus obtained and delivered are rectangular, which facilitates assembly, and the cutting of the top for the top base or the punching is made as appropriate when the straw is inserted or through it.

Additional features of the product:

+ provision of sanitary and hygienic protection of the content;

+ increased consumption due to the comfort and safety of customers who are afraid of the incident Particularly drivers who divert their attention from the road environment);

+ in justified cases can be used to increase the capacity of the vessel.

+ stirring is greatly facilitated except by shaking and straw - eliminating the use of stirrers;

+ throughout the consumption period, the quantity and condition of the contents is monitored - an advantage over any other package of juices, in which it is difficult to establish the quality at purchase and the remainder at consumption;

+ with any other soft juice package it is possible to spray some of the contents through the straw during compression in the initial period, due to the high degree of filling of the packaging. In the proposed construction, this rate is a maximum of 50% for the packaging, and 100% for the container;

+ the shape and length of the bag, except as a symmetrical assembled unit, allow the aesthetic design of the package. Figures of animals, objects, etc. 5), also enhancing the stability of the straw position with one hand use;
