The specific embodiment
With reference to the accompanying drawings embodiments of the present invention are described.In following accompanying drawing, identical member has been marked identical reference marks.For easy understanding, the reduced scale of these accompanying drawings is suitably changed.
Fig. 1 is based on the front view of the metal can of first embodiment of the invention.Metal can 10 shown in Figure 1 includes round-ended cylinder shape metal can body 12 and is crimped the cover 11 of seam to the peristome of metal can body 12.Metal can body 12 and cover 11 are formed by metal, for example aluminum or aluminum alloy.In addition, in metal can 10, fill contents such as beer, sparkling wine, soft drink.
Metal can body 12 mainly comprise bottom 13 and from the bottom 13 beginnings along can body portion 15 that the axis direction of metal can body 12 extends.In Fig. 1, though the internal diameter of can body portion 15 on the axis direction of metal can body 12 about equally, it is different that the internal diameter of can body portion 15 also can part.
As shown in Figure 1, on the outer peripheral face of can body of the present invention portion 15, dispose commodity and represent zone 16, the information that its expression is relevant with the content of metal can 10.And, integrally surround these commodity by peripheral groove 20 and represent zone 16.
As can be seen from Figure 1, peripheral groove 20 comprises that commodity represent that zone 16 is between these first grooves 21a, 21b with respect to the first groove 21a, the 21b of the axis direction almost parallel ground extension of can body portion 15.And, connect the upper and lower end parts of the first groove 21a, 21b respectively at roughly all upwardly extending two auxiliary tank 23a, the 23b of can body portion 15.And, be formed with commodity too in the rear side of metal can 10 and represent zone 16 and peripheral groove 20.And back view and Fig. 1 of metal can 10 are roughly the same.
That is to say, though not shown in figures, on the outer peripheral face of can body portion 15, two commodity are represented that zone 16 is configured to toward each other.At this moment, trade name etc. being illustrated in two commodity represents in the zone 16.
And, on the outer peripheral face of can body portion 15, be formed with roughly all upwardly extending a plurality of second groove 22a~22c, 22a '~22c ' in can body portion 15.As can be seen from Figure 1, second groove 22a~22c extends near the first groove 21b of other peripheral groove near the first groove 21a of peripheral groove 20 in the counterclockwise direction.Equally, second groove 22a '~22c ' extends near the first groove 21a of other peripheral groove near the first groove 21b of peripheral groove 20 along clockwise direction.
And as can be seen from Figure 1, the second groove 22b, 22b ' upwards extended in week of can body portion 15, and remaining second groove 22a, 22a ', 22c, 22c ' extend with respect to the below that circumferentially acutangulates and reach upward respectively of can body portion 15.But these second grooves 22a~22c, 22a '~22c ' make progress to extend in the roughly week of can body portion 15 and get final product, and the quantity of other second groove is not limited to graphic quantity.
In addition, it must be continuous groove that these second grooves 22a etc. does not need, and also can be interrupted groove.And the situation that small-sized recess complex forms second groove 22a etc. as a whole also belongs to scope of the present invention.And,, therefore can understand that second groove 22a~22c, 22a '~22c ' have extended across 1/4 of can body portion 15 outer peripheral faces because the front view and the back view of metal can 10 are roughly the same.
In addition, Fig. 2 a to Fig. 2 c is the partial section of metal can shown in Figure 1.In Fig. 2 a to Fig. 2 c, the second groove 22b is represented as the typical example of second groove.Shown in Fig. 2 a, the cross section of the second groove 22b is triangular in shape., as Fig. 2 b and Fig. 2 c represented respectively, the cross section of the second groove 22b also can be half elliptic and trapezoidal.And the cross section of the first groove 21a, 21b also can be the shape shown in Fig. 2 a to Fig. 2 c.No matter which kind of situation all belongs to scope of the present invention.
As mentioned above, owing to the first groove 21a, the 21b that have formed on metal can 10 of the present invention with respect to the axis direction almost parallel extension of can body portion 15, so resisting longitudinal (axis direction) the heavy burden ability of metal can body 12 and metal can 10 is strengthened.In addition, owing to formed the first groove 21a, the 21b that extends with respect to the axis direction almost parallel of can body portion 15 and formed roughly all upwardly extending second groove 22a~22c, 22a '~22c ' in can body portion 15, therefore the Design freedom of metal can body 12 and metal can 10 can be improved, and decorative effect can be further improved.
In addition, when referring again to Fig. 1, the end of second groove 22a~22c is not connected to the first groove 21a, but keeps apart apart from k with the first groove 21a.Equally, the end of second groove 22a '~22c ' also keeps apart apart from k with the first groove 21b.Also be like this on the rear side of metal can 10.
As mentioned above, especially when cover 11 lock seams or when filling beverage etc., easily metal can 10 is applied vertical heavy burden, consequently, second groove 22a~22c, 22a '~22c ' might buckle.As mentioned above, extended across under the situation more than 1/4 of can body portion 15 outer peripheral faces at second groove 22a etc., the possibility of buckling further improves.But, in the present invention,, so stop at the both ends of the second groove 22a etc. buckling of locating to take place such as the second groove 22a because the first groove 21a, 21b and second groove 22a~22c, 22a '~22c ' keep apart apart from k, do not propagate into the first groove 21a, 21b.In other words, fully can prevent to propagate into the first groove 21a apart from the length of k buckling of locating such as second groove 22a.
And as can be seen from Figure 1, the both ends of all second groove 22a~22c, 22a '~22c ' all keep apart apart from k with the first groove 21a, the 21b of the peripheral groove 20 of face side or rear side.Therefore, can understand,, can positively prevent to be transmitted to the first groove 21a, the 21b of face side or rear side in the influence of buckling that second groove 22a etc. locates to take place.
In addition, as shown in Figure 1, be positioned at commodity and represent that first groove 21a, the 21b of zone between 16 and second groove 22a~22c, the 22a '~22c ' is adjacent to commodity and represents regionally 16, and the second groove 22a etc. and the first groove 21a etc. keep apart apart from k.Therefore, stop at the both ends of the second groove 22a etc., not only propagate less than the first groove 21a etc., also propagate less than commodity and represent zone 16 buckling of locating such as the second groove 22a.Therefore, can prevent that commodity from representing zone 16 distortion or damage.
In addition, as can be seen from Figure 1, dispose second groove 22a~22c and second groove 22a '~22c ' mutually regularly, therefore, can know the decorative effect that has improved metal can body 12.And, even do not exist the situation of auxiliary tank 23a, 23b to be also contained in the scope of the present invention.But, when having auxiliary tank 23a, 23b, can improve the decorative effect that commodity are represented zone 16.And even metal can 100 is being applied under the situation of excessive vertical heavy burden, because auxiliary tank 23a, 23b preferentially buckle, therefore the influence of buckling does not propagate into commodity and represents regionally 16, can protect commodity to represent regional 16.
And, can interconnect second groove 22a~22c by the strengthening groove that on the axis direction of can body portion 15, extends.Equally, also can interconnect second groove 22a '~22c ' by same strengthening groove.Be connected at such strengthening groove under the situation of second groove 22a etc., compare with the situation that does not have strengthening groove, more can reinforced metal jar body 12 and resisting longitudinal (axis direction) the heavy burden ability of metal can 10.And, by such strengthening groove, also can improve the Design freedom of metal can body 12 and metal can 10.But, being connected at strengthening groove under the situation of the second groove 22a etc., the situation that only is formed with strengthening groove with there not being the second groove 22a etc. is compared, and the longitudinal strength of metal can body 12 and metal can 10 descends.
Fig. 3 is based on the front view of the metal can of second embodiment of the invention.As shown in Figure 3, the second groove 22a, 22c also can be circular arc.Perhaps, L font that second groove 22a etc. also can be in wave shape or continuous etc.And the second groove 22a etc. also can be the arbitrary shape beyond the above-mentioned shape, and the second groove 22a etc. also can be a part of shape of for example rhombus, circle, ellipse or these shapes or make up the shape of these shapes.
And,, also go for other metals, for example the metal can of steel though the present invention is applicable to the metal can that aluminum or aluminum alloy is made.Certainly, the invention of any several above-mentioned embodiments of appropriate combination also belongs to scope of the present invention.
