Abstract

1366359 Packaging elements for packaging articles MEDICOR MUVEK 2 Sept 1971 [8 Sept 1970] 41076/71 Heading B8C A packaging element, particularly for protecting packaged articles such as sensitive instruments &c., has two wall portions having surfaces at an angle to one another for engaging corresponding surfaces of an article to be protected, each wall-portion being of self-supporting, double-walled, construction and the space defined within the double-wall of each wall portion including vibration-damping means extending from wall-to-wall of the double wall and having a different response to vibration to that of the double wall such as to act to dampen the transmission of vibrations by the wall portion in which said means is included. As shown, a damper element for receiving a corner of an article to be packaged has three hollow-wallportions a, b, and c mutually at right angles to one another. Vibration-damping inserts g, having the desired resonance frequencies, can be fitted into each hollow wall-portion or, the latter can be filled with gas, or liquid. The outer edges of the elements can be shaped to correspond with the inner surface of the packaging container and grooves d can be provided in the inner walls along the lines of intersection to enhance the flexibility of the element.

Description

Priority: 09/08/1970 Hungarian People's Republic Application announced: 30/04/1973 Patent description was published: 07/31/1975 73870 KI. 81c, 26/01 MKP B65d 81/04 Inventors: József Tórók, József Salamon, Geza Szabó Authorized by the provisional patent: Medicor Muvek, Budapest (Hungarian People's Republic) Vibration damping element, acting in many directions Brzeló ^ niot [the invention is a universal element damping vibrations, acting in many directions. On the packing and transport of rushes, protection of packed goods many problems. In the interests of safe packaging and transportation, numerous solutions and materials are used. The foamed plastics used hitherto have proved to be suitable for the production in large quantities and at low cost of various shaped inserts. For the packaging of various assortments of goods, various elements of various sizes were produced, used to protect the packaging. The big drawback of individually produced vibration dampers is that they can be used only for devices, or for packaged goods in pieces, taking into account their shape. In order to eliminate this inconvenience, a multi-dimensional anti-vibration universal element has been developed, which can be used as a uniform element of the package to dampen vibrations in objects of various shapes, deliberately for the packaging of sensitive (sensitive) instruments and devices, in the same way The invention consists in recognizing that the packaged products can be supported in an advantageous manner at their exposed points and that they can be flexibly loaded with the help of flat-line vibration damping elements and that therefore these elements can be used in a semi-closed area. of homogeneous elements which rumble to support in at least two or more replacements, many advantages are to be expected. The use of homogeneous elements is associated in the first place with the advantage that these elements can be produced in large quantities and inexpensively. Packing of this type with uniform elements is quick and practical and does not require any special qualifications. A further advantage is that an air gap is created between the packaged goods and their outer shell (the box), which reduces the volume and weight, and at the same time makes it possible to lift the packed instrument or the like securely.] By means of uniform elements the load may be concentrated at the points of support, and it may be realized in the most stressed places, that is, at the corners of the outer shell. Uniform elements are not damaged during transport and during packaging and can therefore also be used repeatedly. The design of the universal vibration damping element and operating in many dimensions is primarily based on the fact that each element has at least two walls connected at right angles, and moreover, preferably, but not necessarily a third wall, also placed at a right angle, as well as between the plates delimiting o d inside and outside the wall, vibration damping parts made of flexible material. These constructions are made in at least two as well as three dimensions. If a vibration damping element is used, which works in many dimensions, itio then its external shape may be (different to suit the shape of the external cladding. The invention is explained in more detail on a few examples of execution, shown in the figures in Fig. 1). shows a vibration damping element located in the corner of the outer cladding and operating in three dimensions, fig. 2 - vibration damping element according to fig. 1 with elastic inserts, fig. 3 - vibration damping element according to fig. 1, operating in three in dimensions, with an outer edge cut off, Figure 4 shows the vibration damping element according to Figure 1, which functions in three dimensions, and Figure 5 shows the vibration damping element arrangement shown in Figures 1, 2, 3 and 4, in the lining The individual figures show the vibration damping elements according to the invention, in an axonometric perspective. Fig. 1 shows the vibration damping element operating in fatzech dimensions, located at the corner of the external cladding and delimited by double walls a, b, c In the embodiment example shown in Fig. 2, in double walls a, b, c limiting the uniform element are made of recesses into which it is inserted There are vibration damping inserts, made of a material with different resonance frequencies, on which the corner pantia of the packed goods is attached. In the example shown in Fig. 3, the edges of the outer packages delimiting the uniform vibration damping element are cut off accordingly. The joint modification of the boundary walls of the unitary vibration damping element and any design of its shape are also possible. According to the example shown in Fig. 2, in the limiting walls, operating in three dimensions, there are holes in which further g-inserts are inserted, better vibration damping properties. Inserts inserted in this way provide protection against vibrations © greater h frequencies and lower amplitudes. The vibration damping elements can also be designed in such a way that the boundary wall elements f are hollow inside and a liquid or gas is fed into this empty space, the vibration damping being carried out by; gaseous medium, which may in this case be air, or through a liquid. From the point of view of the material of the vibration damping elements, no further conditions are required in the invention. Polyurethane or other suitable synthetic foams are effective in meeting this task. As can be seen from Fig. 5, the universal vibration damping element according to the invention can be used for fast and safe (reliable) packaging. The advantage also lies in the fact that A favorable proportion of the volume in the packaging device can be obtained, since the air gap between the outer casing and the packed goods can be reduced to a minimum dimension taking into account the safety required in each case. The void thus formed can also advantageously be used to accommodate parts belonging to the equipment, components, 20 printed matter, instructions for use, etc. EN EN
