Definitions
- the invention relates to an element for reciprocally stacking hollow objects such as beakers and like containers, arranged one partially internally of another.
- the problem is generally exhibited for many reciprocally stackable objects as described, where the objects are made of hard material which is accompanied by a risk of reciprocal scratching, and is more serious when the object is precious.
- An aim of the present invention is to realise an element which enables reciprocal stacking of the objects while at the same time preventing direct contact between the external surface of the internal object and the internal surface of the external object; and all with a solution that is relatively very simple and economical.
- the invention is based on the fact that it comprises a tray having a shape such as to be keyable on the external surface of the extreme lower portion of each object located internally of another object, and having a flank which defines a relatively soft spacer which prevents direct contact between the external surface of the internal object and the internal surface of the external object.
- the invention also comprises a group of objects (at least two) stacked on one another where a tray is interposed between them, the tray having a shape such as to be keyable on the external surface of the extreme lower portion of each object located internally of another object, and having a flank which defines a relatively soft spacer which prevents direct contact between the external surface of the internal object and the internal surface of the external object.

- the projections 15 increase the overall thickness of the flank 11 and behave elastically; they deform elastically when they are pressed between two surfaces 35 and 36 (see figure 5B ) thus defining a relatively soft spacer i.e. having an elastic behaviour which is soft to the touch.
- the upper projections 16 have a similar function.

Abstract
Description
- The invention relates to an element for reciprocally stacking hollow objects such as beakers and like containers, arranged one partially internally of another.
- In packing such objects for transport, especially beakers made of glass or crystal, it is preferable to avoid stacking them by inserting one partially internally contained inside another, in order to prevent the reciprocal contact between the external surface of one and the internal surface of another from occasioning scratches, micro-incisions or in any case marks which cannot be removed and which can be seen, all of which would compromise the appearance and value thereof. For this reason, it is preferred to pack these objects singly (i.e. not stacked) side-by-side to one another with the consequence that finished packs are much larger in volume than what might be achieved if they were stacked.
- The problem is generally exhibited for many reciprocally stackable objects as described, where the objects are made of hard material which is accompanied by a risk of reciprocal scratching, and is more serious when the object is precious.
- An aim of the present invention is to realise an element which enables reciprocal stacking of the objects while at the same time preventing direct contact between the external surface of the internal object and the internal surface of the external object; and all with a solution that is relatively very simple and economical.
- This and other aims are attained by the invention as it is characterised in the accompanying claims.
- The invention is based on the fact that it comprises a tray having a shape such as to be keyable on the external surface of the extreme lower portion of each object located internally of another object, and having a flank which defines a relatively soft spacer which prevents direct contact between the external surface of the internal object and the internal surface of the external object.
- The invention also comprises a group of objects (at least two) stacked on one another where a tray is interposed between them, the tray having a shape such as to be keyable on the external surface of the extreme lower portion of each object located internally of another object, and having a flank which defines a relatively soft spacer which prevents direct contact between the external surface of the internal object and the internal surface of the external object.
- The invention is now described in detail with the aid of the accompanying figures of the drawings, which illustrate a preferred though not exclusive embodiment thereof.
-
Figure 1 is a perspective view of the element of the invention. -
Figure 2 is a lateral view offigure 1 . -
Figure 3 is a plan view from above offigure 1 . -
Figure 4 is an axial section of two beakers stacked on one another, with the element offigures 1-3 being interposed between them. -
Figure 4A is a large-scale detail offigure 4 . -
Figure 5 is a section of the element according to plane V-V offigure 4 . -
Figure 5B is a section of the element according to plane V-V offigure 4 , constrained between two beakers during a stacking stage. - The element illustrated in figures from 1 to 3 is constituted by a
tray 10 made of a relatively soft material in contact with the surface of the objects, specifically a material which does not scratch the surface of the objects it is placed between. - The shape of the tray is such that it can be keyed on the external surface of the extreme lower portion of each object located internally of another object.
- The tray illustrated in the figures has a
lateral flank 11 which is overall truncoconical in shape and alower base 12 which is generally flat; the shape of the tray is such that it can be snugly keyed on the extreme lower portion of abeaker 30. - The
tray 10 is destined to prevent direct contact between the external surface of the object (beaker 30b) and the internal surface of the external object (beaker 30a). - To this end the
lateral flank 11 is provided withlateral projections 15 which project radially with respect to the general circumferential development of the transversal section of thewhole flank 11, the projections being such as to increase the overall thickness H of the flank itself (see figure 5A). - In the illustrated embodiment, the
lateral projections 15 define, in a transversal section, a series of concavities, distributed over the whole circumferential development of the flank, having a smaller radius than a radius of the circumference defined by the transversal section of the whole flank. - In particular, the
projections 15 are located in the lower part of theflank 11 and have, in transversal section, an arched shape which projects radially externalwise with respect to the generally circular profile of the section of the flank. Alternatively theprojections 15 can project internalwise. - The illustrated
projections 15 develop in height over a smaller tract than the height of theflank 11, reducing the scope of the arc up to when it disappears, close to theupper edge 11 a of theflank 11. - In the illustrated embodiment in the figures,
projections 16 are also fashioned in the flank in an upper position with respect to theprojections 15, in particular theprojections 16 are fewer than theprojections 15. - The material of the flank is preferably stiff and elastic such that the lateral projections can react elastically to the deformation they are subjected to.
- In particular, the tray is made of polystyrene, having a thickness of 0.4 to 0.8 mm.
- In stacking objects, in
particular beakers 30, located one partially internally of another, thetray 15 is keyed on the extreme lower portion of eachbeaker 30b located internally of another beaker 30A such as to prevent direct contact between the reciprocally facing surfaces of each pair of stacked beakers, i.e. theinternal surface 35 of theexternal beaker 30a and theexternal surface 36 of the internal beaker. - The
projections 15 increase the overall thickness of theflank 11 and behave elastically; they deform elastically when they are pressed between twosurfaces 35 and 36 (seefigure 5B ) thus defining a relatively soft spacer i.e. having an elastic behaviour which is soft to the touch. - The
upper projections 16 have a similar function. - Further, the
projections surfaces - Obviously numerous modifications of a practical-applicational nature might be brought to the invention, without its forsaking the ambit of the inventive idea as claimed herein below.
- In particular, the shape, number and sizes of the projections fashioned on the
lateral flank 11 might be varied. - In particular, the element might have a polygonal section, with the tangential sides to the external surface of the internal beaker and the vertices resting on the internal surface of the external beaker.
- Indeed, the projections can even not be present. In this case the thickness of the material of the flank is preferably greater than mentioned above, said material being intrinsically soft and elastic.
