Description

CAP FOR CONTAINER TUBE
The present invention relates to a cap for a container tube.
Nowadays it is known to make caps, for closing tubes, usually cylindrical, which in transverse cross-section have a substantially upside- down U shape structure, with an inside diameter that slightly exceeds the outside diameter of the tube, and which are therefore adapted to be positioned at the free end of the tube in order to temporarily close it.
The connection and the stable closing between the cap and the tube is obtained by using a plurality of staples, which can be inserted transversely to the side walls of the cap and of the tube and/or by way of for example an adhesive band with a wired tape adapted to reinforce the rim of the tube.
In order to position labels, which bear barcodes, it is further necessary to wrap the wired tape, which wraps around the adhesive band, in adhesive tape.
One drawback that is found in the known art consists in that these conventional caps have a weak structure that does not withstand the stresses of the material placed inside the tube or the pressures exerted outside it which can lead to the cap being forced off.
In fact as soon as these conventional caps are stressed or undergo any pressure, they cave in and break, thus requiring frequent replacements with consequent cost increases or leading to the outflow of the contents and to the damage thereof.
Furthermore the cap, owing to its weak structure, does not ensure an adequate level of protection for the ends of the tube which, if pressure is applied on the upper surface of the cap, will be deformed.
A further drawback consists in that the structure of the cap and of the tube require one to make a connection between the cap and the tube which entails the superimposition of a series of reinforced adhesive bands.
The aim of the present invention is to eliminate the above mentioned drawbacks, by providing a cap for tubes that has a structure that makes it possible to achieve a correct and stable connection to a tube, while simultaneously protecting the free ends of that tube from possible deformations.
Within this aim, an object of the present invention is to obtain a cap that ensures a simple and rapid connection with the tube.
Another object of the present invention is to provide a cap that allows a simple and direct application thereon of labels bearing barcodes.
Another object is to provide a cap that is structurally simple and low cost and can be made with the usual conventional systems.
This aim and these and other objects which will become better apparent hereinafter are achieved by a cap for a container tube according to claim 1.
Further characteristics and advantages of the invention will become better apparent from the detailed description of aparticular, but not exclusive, embodiments of the invention which are illustrated by way of non-limiting example in the accompanying drawings wherein:

In the exemplary embodiments illustrated below, individual characteristics shown in relation to specific examples may in reality be interchanged with other, different characteristics, existing in other exemplary embodiments.
With reference to the figures, the reference numeral 1 generally designates a cap for a container tube 2, which in plan view is polygonal, preferably square, or circular.
By way of example, in the embodiments shown by Figure 1 to Figure 13, the tube 2 has a shape structure that in plan view is substantially square; in the embodiment shown by Figure 14 to Figure 16, the tube 2 has a shape structure that in plan view is substantially circular.
The cap 1 in plan view therefore has a polygonal shape similar to that of the tube 2 and is constituted by a hollow central body 3 that in plan view is a polygon inscribed in a circumference of smaller diameter, or smaller equivalent diameter, than the inside diameter of the tube 2.
The central body 3 has, in a transverse cross-section, a substantially upside-down U shape structure, and has a base 4, slightly inclined toward the center 5, and at least one side wall 6a, 6b, 6c, 6d.
By way of example, in the embodiments shown by Figure 1 to Figure 13, the central body 3 has a shape structure that in plan view is substantially square, with sharp corner edges, and is constituted by a base 4 and by four lateral walls 6a, 6b, 6c, 6d; in the embodiment shown by Figure 14 to Figure 16 the central body 3 has a shape structure that in plan view is substantially circular and has a base 4 and a side part 6a.
The central body 3 has, starting from the first end tip(s) 7a, 7b, 7c, 7d of the lateral wall(s) 6a, 6b, 6c, 6d and radially thereto, the appendage 8 protruding perimetrically and therefore externally with respect to the lateral wall(s) 6a, 6b, 6c, 6d.
The width of the appendage 8 is slightly smaller than the inside diameter of the tube 2.
The annular ridge 10 that has, in cross-section, a substantially upside- down U shape structure so as to define the seat 11 for receiving the complementarily shaped free end 12 of the tube 2, protrudes, perpendicularly and in the direction of the base 4, from the second end tip(s) 9a, 9b, 9c, 9d of the appendage 8.
The annular ridge 10 has an inner lateral surface 13 and an outer lateral surface 14 that abut, when installed, against the complementarily shaped free end 12 of the tube 2, the inner and outer lateral surfaces 13 and 14 of the ridge 10 having a height substantially equal to that of the lateral wall(s) 6a, 6b, 6c, 6d of the central body 3.
The corners are preferably beveled.
The inner and outer lateral surfaces 13, 14 of the ridge 10 have, in the specific embodiment shown, a height substantially equal to that of the lateral wall(s) 6a, 6b, 6c, 6d of the central body 3.
The hollow central body 3 has, at the lower surface 15 of the base 4, a plurality of dividing partitions 16a, 16b, 16c, 16d, 16e, 16f, 16g, 16h, 16i, 161, 16m, 16n, which are adapted to reinforce the structure of the central body 3.
The plurality of partitions 16a, 16b, 16c, 16d, 16e, 16f, 16g, 16h, 16i, 161, 16m, 16n protrude radially starting from the center 5 of the base 4 of the central body 3 and is adapted to divide the inner surface 15 of the base 4 into a plurality of cavities 17. The plurality of partitions 16a, 16b, 16c, 16d, 16e, 16f, 16g, 16h, 16i, 161, 16m, 16n has a height that is greater at the lateral wall(s) 6a, 6b, 6c, 6d of the central body 3, is substantially equal to the height of the lateral wall(s) 6a, 6b, 6c, 6d of the central body 3, and is therefore also equal to the height of the inner and outer lateral surfaces 13, 14 of the annular ridge 10, and smaller at the center 5.
The embodiment shown by Figure 1 to Figure 4 has four first dividing partitions 16a, 16b, 16c, 16d, which protrude radially starting from the center 5 of the base 4 of the central body 3, at the diagonals of the plan of the central body 3, and four cavities 17.
The embodiment shown by Figure 5 to Figure 7 has four second dividing partitions 16e, 16f, 16g, 16h which protrude radially starting from the center 5 of the base 4 of the central body 3 and are adapted to define a cross inscribed in the square plan of the central body 3, in which the length of the arms is shorter than the side of the square, substantially equal to half the length of the side of the square.
These four second dividing partitions 16e, 16f, 16g, 16h are intersected, about halfway along their length, by a first annular partition 16i.
Four first dividing partitions 16a, 16b, 16c, 16d protrude at the diagonals of the square plan of the central body 3, starting from the annular partition 16i up to the respective corner.
The lower surface 15 of the base 4 is therefore provided with twelve seats 17.
The embodiment shown by Figure 8 to Figure 10 has four second dividing partitions 16e, 16f, 16g, 16h which protrude radially starting from the center 5 of the base 4 of the central body 3 and are adapted to define a cross inscribed in the square plan of the central body 3, in which the length of the arms is shorter than the side of the square, substantially equal to half the length of the side of the square.
These four second dividing partitions 16e, 16f, 16g, 16h are intersected by a first and a second annular dividing partition 16i, 161, which are arranged respectively at about one-third and at about two-thirds along their total length.
Four first dividing partitions 16a, 16b, 16c, 16d protrude at the diagonals of the square plan of the central body 3, starting from the first annular dividing partition 16i up to the respective corner, intersecting the second annular dividing partition 161.
The lower surface 15 of the base 4 is therefore provided with twenty seats 17.
The embodiment shown by Figure 11 to Figure 13 has four second dividing partitions 16e, 16f, 16g, 16h which protrude radially starting from the center 5 of the base 4 of the central body 3 and are adapted to define a cross inscribed in the square plan of the central body 3, in which the length of the arms is shorter than the side of the square, substantially equal to half the length of the side of the square.
These four second dividing partitions 16e, 16f, 16g, 16h are intersected by a first, by a second and by a third annular dividing partition 16i, 161, 16m, which are arranged respectively at about one-quarter, half, and three-quarters along their total length.
Four first dividing partitions 16a, 16b, 16c, 16d protrude at the diagonals of the square plan of the central body 3, starting from the first annular dividing partition 16i up to the respective corner, intersecting the second and third annular dividing partitions 161, 16m.
These first and second partitions 16a, 16b, 16c, 16d, 16e, 16f, 16g, 16h are intersected by a first square partition 16m that circumscribes the third partition 161.
The lower surface 15 of the base 4 is therefore provided with thirty- five seats 17.
The embodiment shown by Figure 14 to Figure 16 has four second dividing partitions 16e, 16f, 16g, 16h which protrude radially starting from the center 5 of the base 4 of the central body 3 and are adapted to define a cross inscribed in the circular plan of the central body 3.
Use of the invention is therefore the following: the ridge 10 of the cap
1 is positioned at the free end 12 of the tube 2; a light pressure is applied to the tube 2, resulting in the stable connection with the cap 1 by virtue of the fact that the ridge 10 completely envelops the free ends 12 of the tube 2, and its inner lateral surface 13 applies a pressure on the inner lateral surface of the tube 2.
By making the cap 1 of plastic material, the appendage 8 and the central body 3 are elastically deformable so that they contribute to the optimal adhesion of the inner lateral surface 13 of the ridge 10 to the inner lateral surface of the tube 2.
The stable connection between the cap 1 and the tube 2 can be obtained using conventional staples 18, which can be inserted transversely to the ridge 10 and to the tube 2.
Thus it has been found that the invention fully achieves the intended aim and objects, a cap 1 for tubes 2 having been obtained which has a structure that is strong and is at the same time adapted to protect the free end 12 of the tube 2, by virtue of the presence and the shape structure of the annular ridge 10 whose walls protect and envelop the free end 12 of the tube
2 which is accommodated in the seat 11 of the ridge 10.
Furthermore the appendage 8 and the central body 3 of the cap 1 are elastically deformable, thus contributing to the optimal adhesion of the inner lateral surface 13 of the ridge 10 to the inner lateral surface of the tube 2.
It has further been found that the cap 1 ensures a simple and rapid connection with the tube 2, requiring the application, as an element external to the cap 1 , of conventional staples 18 for an additional mechanical grip.
Finally, any labels bearing barcodes can be directly attached, simply and rapidly, to the surface of the cap 1 at the base 4 of the central body 3.
The invention is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims.
Naturally the materials used as well as the dimensions of the individual components of the invention may be more relevant according to specific requirements.
The characteristics indicated above as advantageous, convenient or the like, may also be missing or be substituted by equivalent characteristics.
