Description
本發明係有關一種為了啤酒、發泡酒及清涼飲料等之內容物的金屬罐本體及金屬罐。The present invention relates to a metal can body and a metal can for contents of beer, sparkling wine, and refreshing beverage.
長久以來為了填充啤酒、發泡酒及清涼飲料等之內容物而使用金屬罐，例如鋁合金製的罐子。通常，將內容物填充於具有底部與罐身部之有底圓筒狀之金屬罐本體，且將罐蓋捲繞固定於開口部而形成金屬罐。A metal can, for example, a can made of an aluminum alloy, has been used for a long time to fill contents such as beer, sparkling wine, and refreshing beverage. Usually, the contents are filled in a bottomed cylindrical metal can body having a bottom portion and a can body portion, and the can lid is wound and fixed to the opening portion to form a metal can.
第4圖係習知技術之金屬罐的側面圖。如第4圖所示，在習知技術之金屬罐100為了增加設計之自由度，有在金屬罐100罐身部150的外周面形成複數朝圓周方向延伸之橫溝220的情況。如此之橫溝也形成在專利文献1及專利文獻2所揭示的金屬罐上。Figure 4 is a side view of a metal can of the prior art. As shown in FIG. 4, in the metal can 100 of the prior art, in order to increase the degree of freedom of design, a plurality of lateral grooves 220 extending in the circumferential direction are formed on the outer circumferential surface of the can body portion 150 of the metal can 100. Such a lateral groove is also formed in the metal can disclosed in Patent Document 1 and Patent Document 2.

發明所欲解決的課題Problem to be solved by the invention
第5a圖及第5b圖係習知技術之金屬罐的部分斷面圖。如該等圖面所示，縱方向之重量施加於金屬罐時，橫溝220挫屈且金屬罐100之外周面變形。如此之挫屈作用不只是在堆積複數金屬罐100時發生，在將罐蓋捲繞固定於金屬本體之開口部時也會產生。捲繞固定之際發生挫屈時，所填充之內容物也同時廢棄損失。若是提高金屬罐本體的厚度雖會使挫屈難以發生，但是飲用後卻難以壓壞，在回收再利用之面等會產生不適的情況。也就是，在不提高罐身部150之厚度而只在罐身部150之外周面形成橫溝220的情況，從維持金屬罐100之縱方向強度，特別是抑制捲繞固定罐蓋時之廢棄損失的觀點來看是有困難的。Figures 5a and 5b are partial cross-sectional views of metal cans of the prior art. As shown in the drawings, when the weight in the longitudinal direction is applied to the metal can, the lateral groove 220 is frustrated and the outer circumferential surface of the metal can 100 is deformed. Such a frustening action occurs not only when a plurality of metal cans 100 are stacked, but also when the can lid is wound and fixed to the opening of the metal body. When the winding occurs and the setback occurs, the contents to be filled are also discarded. If the thickness of the metal can body is increased, the setback is hard to occur, but it is difficult to crush after drinking, and the surface to be recycled and reused may cause discomfort. In other words, when the lateral groove 220 is formed only on the outer circumferential surface of the can body portion 150 without increasing the thickness of the can body portion 150, the strength in the longitudinal direction of the metal can 100 is maintained, and in particular, the disposal of the can lid is suppressed. The point of view of loss is difficult.
又，專利文献1及專利文獻2所揭示之金屬罐係以於其使用後易於壓壞為目的，而將橫溝形成於罐身部150之外周面。也就是，在專利文献1及專利文献2並未設想要維持金屬罐100之縱方向的強度。Further, the metal cans disclosed in Patent Document 1 and Patent Document 2 are formed so as to be easily crushed after use, and the lateral grooves are formed on the outer circumferential surface of the can body portion 150. In other words, Patent Document 1 and Patent Document 2 do not intend to maintain the strength of the metal can 100 in the longitudinal direction.
另一方面，將於軸線方向延伸之縱溝(未圖示)形成於罐身部150之外周面時，可對縱方向之重量強化金屬罐100。但是，如此之縱溝與前述之橫溝相互相接時，橫溝上所產生之挫屈的影響會傳播到縱溝，而有使縱溝變形的可能性。特別是，商品顯示區域(未圖示)與縱溝相鄰而配置於外周面150時，會引起商品顯示區域本身的變形。On the other hand, when a vertical groove (not shown) extending in the axial direction is formed on the outer circumferential surface of the can body portion 150, the metal can 100 can be reinforced against the weight in the longitudinal direction. However, when such a longitudinal groove and the aforementioned lateral groove are in contact with each other, the influence of the buckling generated on the lateral groove propagates to the longitudinal groove, and there is a possibility that the longitudinal groove is deformed. In particular, when the product display region (not shown) is disposed adjacent to the vertical groove and disposed on the outer circumferential surface 150, the product display region itself is deformed.
因此，本發明人為克服上述課題而反覆刻意研究的結果，藉由使縱溝與橫溝相互相離，而獲得可不使橫溝所產生之挫屈的影響傳播到縱溝的見識，以至完成本發明。Therefore, the inventors have repeatedly conducted deliberate research to overcome the above problems, and by obtaining the longitudinal groove and the lateral groove, the knowledge that the influence of the buckling caused by the lateral groove can be transmitted to the longitudinal groove is obtained, and the present invention is completed. invention.
亦即，本發明係鑒於如此之事情而完成者，以提供一種防止橫溝所產生之挫屈的影響傳播至縱溝，且提高設計之自由度，並且相較縱方向之重量為較強的金屬罐本體及金屬罐為目的。That is, the present invention has been accomplished in view of such a thing, to provide an effect of preventing the influence of the buckling caused by the lateral groove from propagating to the longitudinal groove, and to improve the degree of freedom of design, and is stronger than the weight in the longitudinal direction.

以下，參照添附圖面說明本發明之實施形態。於以下之圖面中，對相同構件附予相同之參照符號。為了易於理解，會將該等圖面適當地變更比例尺。Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the following drawings, the same reference numerals are attached to the same members. For ease of understanding, the scales are appropriately changed in scale.
第1圖係依據本發明第1實施形態之金屬罐的正面圖。第1圖所示之金屬罐10係由有底圓筒狀之金屬罐本體12、捲繞固定於金屬罐本體12之開口部的罐蓋11所構成。金屬罐本體12及罐蓋11係由金屬，例如鋁或鋁合金形成。又，使啤酒、發泡酒及清涼飲料等之內容物填充於金屬罐10。Fig. 1 is a front view of a metal can according to a first embodiment of the present invention. The metal can 10 shown in Fig. 1 is composed of a bottomed cylindrical metal can body 12 and a can lid 11 which is wound and fixed to an opening of the can body 12. The metal can body 12 and the can lid 11 are formed of a metal such as aluminum or an aluminum alloy. Moreover, the contents of beer, sparkling wine, and refreshing drink are filled in the metal can 10.
金屬罐本體12主要包含底部13、由底部13朝金屬罐本體12之軸線方向延伸之罐身部15。於第1圖中，罐身部15之內徑於金屬罐本體12之軸線方向大致相等，惟，罐身部15之內徑也可部分相異。The can body 12 mainly includes a bottom portion 13 and a can body portion 15 extending from the bottom portion 13 toward the axial direction of the can body 12. In the first drawing, the inner diameter of the can body portion 15 is substantially equal in the axial direction of the can body 12, but the inner diameter of the can body portion 15 may be partially different.
如第1圖所示，於本發明之罐身部15外周面配置有顯示有關金屬罐10之內容物資訊的商品顯示區域16。且，該商品顯示區域16係由周圍溝20而包圍全體。As shown in Fig. 1, a product display region 16 for displaying information on the contents of the metal can 10 is disposed on the outer peripheral surface of the can body portion 15 of the present invention. Further, the product display region 16 is surrounded by the surrounding grooves 20 as a whole.
由第1圖可瞭解，周圍溝20包含相對罐身部15之軸線方向概呈平行延伸之第一溝21a、21b，且商品顯示區域16配置於該等第一溝21a、21b之間。再者，於罐身部15之大略圓周方向延伸的二個補助溝23a、23b係將第一溝21a、21b之上下端部分別連結。又，商品顯示區域16及周圍溝20同樣地也形成於金屬罐10之背面側。而且，金屬罐10之背面圖係使與第1圖大致相同。As can be seen from Fig. 1, the peripheral groove 20 includes first grooves 21a and 21b extending substantially in parallel with respect to the axial direction of the can body portion 15, and the product display region 16 is disposed between the first grooves 21a and 21b. Further, the two auxiliary grooves 23a and 23b extending in the substantially circumferential direction of the can body portion 15 are connected to the upper end portions of the first grooves 21a and 21b, respectively. Further, the product display region 16 and the surrounding groove 20 are also formed on the back side of the metal can 10 in the same manner. Further, the rear view of the metal can 10 is substantially the same as that of Fig. 1.
也就是，雖未顯示於圖面，但是於罐身部15之外周面，二個商品顯示區域16係相互對向配置。於如此之情況，係使商品名等顯示於二個商品顯示區域16。That is, although not shown in the drawing, the two product display areas 16 are arranged to face each other on the outer peripheral surface of the can body portion 15. In such a case, the product name or the like is displayed on the two product display areas 16.
再者，於罐身部15之外周面形成有朝罐身部15之大略圓周方向延伸的複數第二溝22a～22c、22a’～22c’。由第1圖可瞭解，第二溝22a～22c係由周圍溝20之第一溝21a附近沿反時針旋轉延伸至另一周圍溝的第一溝21b附近。同樣地，第二溝22a’～22c’從周圍溝20之第一溝21b附近沿順時針旋轉延伸到另一周圍溝之第一溝21a附近。Further, a plurality of second grooves 22a to 22c, 22a' to 22c' extending in the substantially circumferential direction of the can body portion 15 are formed on the outer peripheral surface of the can body portion 15. As can be understood from Fig. 1, the second grooves 22a to 22c are extended from the vicinity of the first groove 21a of the peripheral groove 20 in the counterclockwise direction to the vicinity of the first groove 21b of the other surrounding groove. Similarly, the second grooves 22a' to 22c' extend from the vicinity of the first groove 21b of the peripheral groove 20 in the clockwise direction to the vicinity of the first groove 21a of the other surrounding groove.
再者，從第1圖可瞭解，第二溝22b、22b’係於罐身部15之圓周方向延伸，剩下之第二溝22a、22a’、22c、22c’係相對罐身部15之圓周方向成銳角而於上方及下方分別延伸。但是，該等第二溝22a～22c、22a’～22c’也可於罐身部15之大略圓周方向延伸，又，第二溝之數量並不限於圖示者。Furthermore, as can be understood from Fig. 1, the second grooves 22b, 22b' extend in the circumferential direction of the can body portion 15, and the remaining second grooves 22a, 22a', 22c, 22c' are opposed to the can body portion 15. The circumferential direction forms an acute angle and extends above and below. However, the second grooves 22a to 22c and 22a' to 22c' may extend in the substantially circumferential direction of the can body portion 15, and the number of the second grooves is not limited to those shown.
又，該等第二溝22a等並非一定必需連續，也可為間斷。再者，即使是將小型之凹部的集合體作為全體而形成第二溝22a等之情況也包含在本發明的範圍。而且，由於金屬罐10之正面圖與背面圖係大致相同，因此可瞭解第二溝22a～22c、22a’～22c’係橫跨於罐身部15之外周面的至少四分之一而延伸者。Further, the second grooves 22a and the like are not necessarily required to be continuous, and may be intermittent. In addition, the case where the second groove 22a or the like is formed as a whole of the small concave portion assembly is included in the scope of the present invention. Further, since the front view and the rear view of the metal can 10 are substantially the same, it can be understood that the second grooves 22a to 22c, 22a' to 22c' extend over at least one quarter of the outer peripheral surface of the can body portion 15. By.
而且，第2a圖至第2c圖係顯示於第1圖之金屬罐的部分斷面圖。於第2a圖至第2c圖中，係將第二溝22b作為第二溝之代表例而顯示。如第2a圖所示，第二溝22b之斷面係形成三角形狀。但是，如分別於第2b圖及第2c圖所示般，第二溝22b之斷面也可形成半橢圓及梯形。再者，第一溝21a、21b也可是第2a圖至第2c圖所示的形狀。任一種情況皆包含在本發明之範圍。2a to 2c are partial cross-sectional views of the metal can shown in Fig. 1. In Figs. 2a to 2c, the second groove 22b is shown as a representative example of the second groove. As shown in Fig. 2a, the cross section of the second groove 22b is formed in a triangular shape. However, as shown in Figs. 2b and 2c, respectively, the second groove 22b may have a semi-elliptical shape and a trapezoidal shape. Further, the first grooves 21a and 21b may have shapes as shown in Figs. 2a to 2c. Either case is included in the scope of the invention.
如此，由於在本發明之金屬罐10形成有相對罐身部15之軸線方向概呈平行延伸之第一溝21a、21b，所以金屬罐本體12及金屬罐10相對縱方向(軸線方向)之重量被強化。又，由於形成有朝相對罐身部15之軸線方向概呈平行之方向延伸之第一溝21a、21b、及朝罐身部15之大略圓周方向延伸之第二溝22a～22c、22a’～22c’，所以可提高金屬罐本體12及金屬罐10之設計自由度，且可更提高裝飾效果。As described above, since the metal can 10 of the present invention has the first grooves 21a and 21b extending in parallel with respect to the axial direction of the can body portion 15, the weight of the can body 12 and the metal can 10 relative to the longitudinal direction (axial direction) is obtained. Be strengthened. Further, the first grooves 21a and 21b extending in the direction substantially parallel to the axial direction of the can body portion 15 and the second grooves 22a to 22c and 22a' extending in the substantially circumferential direction of the can body portion 15 are formed. 22c', so that the design freedom of the metal can body 12 and the metal can 10 can be improved, and the decorative effect can be further improved.
而且，再參照第1圖，第二溝22a～22c之端部並不與第一溝21a連結，且與第一溝21a僅相離開距離k。同樣地，第二溝22a’～22c’之端部也與第一溝21b僅相離開距離k。於金屬罐10之背面側也是相同的。Further, referring to Fig. 1, the end portions of the second grooves 22a to 22c are not connected to the first groove 21a, and are separated from the first groove 21a by a distance k. Similarly, the end portions of the second grooves 22a' to 22c' are also separated from the first groove 21b by a distance k. The same is true on the back side of the metal can 10.
如前述，金屬罐10特別是在罐蓋11捲繞固定時或是在填充飲料等時易於在縱方向施加重量，其結果，第二溝22a～22c、22a’～22c’有可能會挫屈。如前述，在第二溝22a等橫跨罐身部15之外周面之四分之一以上延伸時，挫屈的可能性會更高。但是，於本發明中，第一溝21a、21b與第二溝22a～22c、22a’～22c’由於僅相離開距離k，所以在第二溝22a等產生之挫屈會在第二溝22a等之兩端部停止，而不會傳播到第一溝21a、21b。換言之，距離k係充分長而足以防止第二溝22a等之挫屈傳播到第一溝21a。As described above, the metal can 10 is easy to apply weight in the longitudinal direction particularly when the can lid 11 is wound and fixed or when a beverage or the like is filled, and as a result, the second grooves 22a to 22c, 22a' to 22c' may be frustrated. . As described above, when the second groove 22a or the like extends over a quarter or more of the outer peripheral surface of the can body portion 15, the possibility of frustration is higher. However, in the present invention, since the first grooves 21a and 21b and the second grooves 22a to 22c and 22a' to 22c' are separated from each other by the distance k, the buckling generated in the second groove 22a or the like may occur in the second groove 22a. Both ends are stopped and do not propagate to the first grooves 21a, 21b. In other words, the distance k is sufficiently long to prevent the buckling of the second groove 22a or the like from propagating to the first groove 21a.
再者，從第1圖可瞭解，全部之第二溝22a～22c、22a’～22c’的兩端部係從正面側或背面側之周圍溝20之第一溝21a、21b僅相離開距離k。因此，可瞭解可確實防止在第二溝22a等所產生之挫屈的影響傳播到正面側或背面側之第一溝21a、21b。Further, as can be seen from Fig. 1, both end portions of all of the second grooves 22a to 22c and 22a' to 22c' are separated from each other by the first grooves 21a and 21b of the peripheral groove 20 on the front side or the back side. k. Therefore, it can be understood that the first grooves 21a and 21b which are propagated to the front side or the back side can be surely prevented from being affected by the influence of the buckling generated in the second groove 22a or the like.
又，如第1圖所示，位於商品顯示區域16與第二溝22a～22c、22a’～22c’之間的第一溝21a、21b係與商品顯示區域16鄰接，再者，第二溝22a等係從第一溝21a等僅相離開距離k。因此，第二溝22a等之挫屈在第二溝22a等之兩端部停止，且不只不會傳播至第一溝21a等，也不會傳播至商品顯示區域16。。因此，可防止商品顯示區域16變形或破損。Further, as shown in Fig. 1, the first grooves 21a and 21b located between the product display region 16 and the second grooves 22a to 22c and 22a' to 22c' are adjacent to the product display region 16, and further, the second groove 22a or the like is separated from the first groove 21a or the like by only the distance k. Therefore, the buckling of the second groove 22a or the like is stopped at both end portions of the second groove 22a or the like, and does not propagate to the first groove 21a or the like, and does not propagate to the product display region 16. . Therefore, the article display area 16 can be prevented from being deformed or broken.
再者，從第1圖可瞭解，第二溝22a～22c及第二溝22a’～22c’係相互規則地配置，藉此，可瞭解提高了金屬罐本體12之裝飾效果。又，即使在補助溝23a、23b不存在的情況也包含在本發明之範圍。但是，在補助溝23a、23b存在時，可提高商品顯示區域16之裝飾效果。再者，即使過大之縱方向的重量施加於金屬罐100時，由於補助溝23a、23b會優先挫屈，所以挫屈之影響不會傳播至商品顯示區域16，而可保護商品顯示區域16。Further, as is understood from Fig. 1, the second grooves 22a to 22c and the second grooves 22a' to 22c' are regularly arranged to each other, whereby it is understood that the decorative effect of the can body 12 is improved. Further, even when the auxiliary grooves 23a and 23b are not present, they are included in the scope of the present invention. However, when the auxiliary grooves 23a and 23b are present, the decorative effect of the product display area 16 can be improved. Further, even if the excessively large weight in the longitudinal direction is applied to the metal can 100, since the auxiliary grooves 23a and 23b are preferentially frustrated, the influence of the buckling does not propagate to the product display region 16, and the product display region 16 can be protected.
而且，也可藉由朝罐身部15之軸線方向延伸之補強溝25而使第二溝22a～22c相互連結。同樣地，第二溝22a’～22c’也可藉由同樣的補強溝而互相連結。如此之補強溝25連結於第二溝22a等時，較補強溝25不存在的情況，可使金屬罐本體12及金屬罐10相對縱方向(軸線方向)之重量強化。再者，藉由如此之補強溝25也可提高金屬罐本體12及金屬罐10之設計自由度。但是，在補強溝25與第二溝22a等連結的情況，較第二溝22a等不存在而只形成補強溝25的情況，金屬罐本體12及金屬罐10之縱方向的強度會變低。Further, the second grooves 22a to 22c may be coupled to each other by the reinforcing groove 25 extending in the axial direction of the can body portion 15. Similarly, the second grooves 22a' to 22c' may be coupled to each other by the same reinforcing groove. When the reinforcing groove 25 is connected to the second groove 22a or the like, the weight of the metal can body 12 and the metal can 10 can be strengthened in the longitudinal direction (axial direction) when the reinforcing groove 25 does not exist. Furthermore, the degree of freedom in designing the can body 12 and the canister 10 can be improved by such a reinforcing groove 25. However, when the reinforcing groove 25 is connected to the second groove 22a or the like, the reinforcing groove 25 is formed only when the second groove 22a or the like does not exist, and the strength of the metal can body 12 and the metal can 10 in the longitudinal direction is lowered.
第3圖係依據本發明第二實施形態之金屬罐的正面圖。如第3圖所示，第二溝22a、22b也可是圓弧形。或者，第二溝22a等也可是波形或連續L字形。再者，第二溝22a等也可是上述以外之任何形狀，第二溝22a等例如也可是菱形、圓形、橢圓形或是該等之一部分或組合。Figure 3 is a front elevational view of a metal can according to a second embodiment of the present invention. As shown in Fig. 3, the second grooves 22a, 22b may also have a circular arc shape. Alternatively, the second groove 22a or the like may be in a wave shape or a continuous L shape. Further, the second groove 22a or the like may have any shape other than the above, and the second groove 22a or the like may be, for example, a diamond shape, a circular shape, an elliptical shape, or a part or a combination thereof.
而且，雖將本發明適用於鋁或鋁合金製之金屬罐，然而其他金屬，例如也可適用於鋼製之金屬罐。當然，將前述之實施形態之幾個予以適當組合也包含於本發明之範圍。Further, although the present invention is applied to a metal can made of aluminum or an aluminum alloy, other metals, for example, can also be applied to a metal can made of steel.
