Abstract

Disclosed is a can opening structure which can smoothly cut open a smiling mouth shape having a wide but sharp curve, which cannot be achieved by existing can openings with a narrow width. The can of the present invention comprises: a plurality of detached and protruding pressing portions that are separately provided for cutting open a discharge port stopper with the smiling mouth shape having the wide width and sharp curves at the edges; and welded protrusions for securely activating specific pressing portions first; wherein the distances (34-A, B, C) from the area pressed by a discharge port cover corresponding to each of the pressing portions to a closest spot on a predicted cutting groove are differentiated. Of course, the spot which should be set as in the closest distance is the spot (34-A) that is closest to one of the edges of the mouth from which the initial fracture begins. In the can of the present invention, the initial fracture begins near the left edge of the mouth, and the shearing of the right mouth portion is delayed while being completely uncompressed until the shearing of the cutting groove continues by means of tilting an opener up to before completing the sharp curve of the left edge of the mouth (before the left edge of the mouth is completely cut open). As a result, when one of the sharp curves of one side of the edge of the mouth is securely cut open, the rest of the cutting open process can be can be smoothly achieved with little effort, and ultimately, a user can securely open a can discharge port stopper with the smiling mouth shape having a wide horizontal opening width even with a simple action of tilting the can opener as with existing cans. 통상의 좁은폭 캔 따개로 도려낼 수 없는 넓고 예리한 커브를 갖는 웃는 입 모양을 매끈하게 도려낼 수 있는 캔 개봉 구조가 개시된다. 본 발명의 캔은 넓은 폭과 예리한 가장자리 커브를 갖는 웃는 입모양의 토출구를 절개하기 위해서 복수 개의 별도 분리 돌출된 누름부와, 특정 누름부만을 확실하게 먼저 활성화시키기 위한 압접돌기 등의 구조를 갖고 있으며, 각 누름부에 대응되는 토출구 마개의 눌림영역과 최근거리에 있는 예상 절개홈 지점까지의 거리(34-A,B,C)에 차등을 두었다. 물론 이때 가장 가까운 거리로 설정해야 할 지점은 최초 파단이 일어나는 어느 한쪽 입 가장자리에 가장 가까운 지점(34-A)이다. 본 발명의 캔은 왼쪽 입 가장자리 근처에서 최초 파단이 일어나고, 이후 따개의 기울임에 의해 절개홈의 전단이 진행되어 왼쪽 입 가장자리의 예리한 커브를 완전히 돌아나오기 전까지(왼쪽 입꼬리가 완전히 도려내어지기 전까지), 오른쪽 입 부분이 확실하게 미 압착상태로 전단 지연된다. 이처럼 어느 한쪽 입꼬리의 예리한 커브가 확실히 먼저 절개되고 나면 나머지 절개과정은 작은 힘으로도 매끈하게 이루어지며 결과적으로 사용자는 종래의 캔과 같은 단순한 캔 따개 기울임 동작만으로도 웃는 입 모양의 넓은 가로절개폭을 갖는 캔 토출구마개를 확실하게 개봉할 수 있다.

Description

Cans with smiling top structure

The present invention relates to a can opening structure to have a differentiated merchandise unlike conventional cans by cutting the discharge port shape into a smile mouth shape in the can opening process.

Millions of cans produced / consumed worldwide worldwide, including the mainstream two-piece can, which is sealed in two pieces: the top cover and the bottom container. And advanced design to reduce the consumption of aluminum and increase the recycling rate while having the strength to meet both the storage quality and the storage quality.

Since the stay-on-tap structure has become the mainstream of the market as a representative recycling design, even after opening, most can designs have been continuously standardized and standardized. A substantial end stage has been reached.

* Examples of can standardization design include, for example, the manufacturing of deep-drawing of a container. The bottom structure of the can is the seaming of the top cover of the top of the container. The lower rim has been dimensioned slightly so that it can be seated correctly inside the rim, allowing for multiple stacks of cans with accuracy and ease.

In addition, when looking at the top structure of the can, the opener is arranged at a position below a predetermined height of the seam edge and an area within a predetermined diameter, so that the opener can be completely stored in the recess of the bottom of the can. The top of the can was able to evenly support the bottom of the can loaded on the upper floor. Therefore, the ultra-thin aluminum can instead of the iron can of the past has sufficient strength for multi-layer loading, thereby enabling mass logistics automation. The top cover of the can, of course, can be made into a complete cylinder without seams and seaming within the outer diameter of the container, making it easy to adapt to the canopy transfer and vending system.

Referring to the prior art of Fig. 10 (Prior Art) of the can is widely used can be as follows. First, by pressing a portion of the inner edge of the discharge hole stopper 11 'to the corner of the opener 20 by using the lever effect, a portion that is pressed by the opener is recessed and a break point is generated nearby.

Next, the ejection stopper 11 'is cut out while the shearing action (incision) spreads along the outlet's cutting groove 14' that is set to be included in the incision line. The cutout is pushed into the can. At this time, in order to be able to easily open a well-sealed metal can with a small force (break along the incision groove and to be easy to cut out afterwards), the lever effect of the opener 20 'must be maximized, and the discharge stopper 11 It is necessary that the pressing point and the pressing progress direction of the opener pressing ') and the pressing point and the pressing progress direction of the ejection opening cutout 14' should be as close and parallel as possible.

(Patent Document 1) Korean Unexamined Patent Publication No. 10-2009-0088685 The opening structure of a can in which the starting point of the pressing force of the opener and the break start point of the discharge plug 11 are as close as possible.

(Previous Patent Document 2) Korean Unexamined Patent Publication No. 10-0942867 The opening structure of the can which puts the projection at the break start point of the discharge stopper so that the breakage of the discharge hole cut groove can be started only by the rotation of the opener.

(Previous Patent Document 3) Korean Unexamined Patent Publication No. 10-0712313 An opening structure of a can having a structure in which an additional cutting groove is placed in the center of the discharge stopper so that the discharge hole is cut off on both sides.

(Patent Document 4) US Patent Publication US 5,405,039 An opening structure of a can that is cut in a smile with a semicircular discharge plug.

Among the prior art documents introduced above, referring to the first document, the press opening force of the can opener is placed as close as possible to the area where the fracture starts among the ejection openings in the lower right corner of the opener that is pressed down when the opener is tilted. You can see the configuration maximized. In this case, the functional side is good, but the discharge port is narrowed, or in many cases, either one of the discharge or opener is biased or tilted to one side after opening, so it is difficult to expect a satisfaction side that stimulates the user's sensitivity when opening or drinking.

Review the second literature. Also, the technical consideration of the pressing force acting point of the can opener and the starting point of breakage of the discharge opening is presented, and when the can opener is slightly rotated by placing the protrusion at the corresponding point, the structure is introduced so that the breaking starts at the correct position while pressing the protrusion. have. As a result, the maximum force required to open the can can be reduced, but it requires a double operation that is somewhat distance from the current standard usage of the can, and stimulates the user's emotion regardless of its functional efficiency. It is difficult to deliver a simple yet satisfactory pleasure in the opening operation itself.

Referring to the third document, as in the first and second documents, it is also possible to find the middle incision groove structure as an added configuration to maximize the use of the opener pressing force. However, the structure that is simultaneously cut vertically and horizontally from the center point can reduce the total required force of the can opener, but the shape of the discharge port remains the same, so it can not be said that the user's emotion is further stimulated compared to the conventional can. If the opener is slightly biased to one side in the process of opening the can due to the incision groove added in the middle, only half of the discharge port may be cut because the pressing force is not properly transmitted to the opposite incision groove.

Referring to the fourth document which seems to be similar to the can discharge hole structure of the present invention to be described below, the discharge hole is intended to be widely cut into a semi-circular smile when the opener is inclined. However, there is no technical support for the opening structure of the opener and consequent progression of the incision, which makes this intention possible. According to the experiments of the present inventors, when only the area of the discharge hole cutting groove is expanded to cut the enlarged semicircular discharge hole as described in the above literature, the pressing force of the opener does not work properly at the proper starting point of break of the discharge plug, so Shear action itself is difficult to occur, and after discharging the stopper, which ignores it and continues to incline, only a significant amount of depression is left in the middle without incision, and then the effective tilt trajectory of the opener ends and the opener is bent. That is, it is impossible to properly implement the smile shape of the discharge port to entertain the user at the time of opening as in the present invention only with the drawings and technical contents described in the above document.

An object of the present invention is to create a top cover structure of the emotionally superior cans to open the can overlooking the can, to deliver a smile to the consumer after the opening of the can until the end of the drink intake, but this structure is also technically It is complete and can be handled and distributed perfectly within current commercially available industrial standards and makes it possible to operate with a probability close to 100% in actual consumption. That is, the cans are manufactured while satisfying the application conditions of the deep drawing and seaming processes according to the standardization, and satisfying the width, length, and cross-sectional thickness of the cutout required by the commercialized material, or they can be manufactured in a simple form and at low cost. Even in the highly efficient design can produced, the shape of the top of the can can be repeatedly reproduced with a high probability of the smile-shaped discharge port shape that is fully expanded upon opening.

In order to achieve the object of the present invention, in the present invention, despite the normal tilting motion of the opener in the smiling mouth-shaped discharge port, it was focused on the area of the discharge port incision groove 14, which is expected to be difficult to make a smooth incision.

First, when setting up a normal smiling mouth cut with a wide width horizontally and a sharp curve at the edge of the mouth, it is obvious that the corner width of the usual opener is too short to set the point where the break first begins as the mouth edge. Do. However, in order to solve this problem, if the opener is extended too wide, it will not only cause a large loss of material but also smooth tilting movement. Even if the opener is widened even if it is stretched, the structural strength of the opener manufactured by simple press molding will be far from the support point. It was difficult to deliver the push force far away.

Therefore, in the present invention, but the introduction portion of the presser 20 formed in the shape of a human nose having a slightly enlarged width of the pressing portion in the normal width, but separately pushed separately projecting pressing portion so that the pressing force can be effectively started in the maximum edge area of the opener A plurality of (21-A, B, C) were formed. In this case, as compared with the conventional can opener which does not have a separate push part, the initial break point 32 can be generated at a certain position biased to one side as surely as possible. In this case, the pressure contact protrusion 13 serving as a support point is designed as a non-circular protrusion that holds the opener so as not to rotate in the horizontal direction when riveted to support the intended action.

As described above, if the barnacle is fixed with a pressurization protrusion so as not to rotate in the horizontal direction, and only the exact vertical trajectory can be inclined, a symmetrical opener may be simultaneously pressed at two corners. However, this is not a desirable phenomenon. Because if you press both sides of the mouth at the same time, even if two breakpoints occur almost at the same time or if one diarrhea occurs first, the cutting edge of the mouth is pulled inward as the cutting pressure is applied to the opposite corner. .

This is the main reason why conventional narrow can openers are unable to smooth out the edges of the mouth with wide and sharp curves. Specifically, the direction of the opener push force should be as parallel as possible to the shear advance direction of the incision groove, where the push force is wide in a semicircle, substantially simultaneously at both corners, or a sharp curve at the smiley edge. If you start to press the middle part when you have not come back, as a result, the direction of advance of the pressing force and the direction of shear of the incision groove intersect or even reverse. In this case, the edge of the mouth is pressed close to the incision line and cannot be cut out smoothly but is pulled away (torn away), and then the incision is delayed. If again, as described above, prior art 0004 is no longer the cutting groove shear phenomenon occurs and eventually the tilting operation of the opener will fail.

In order to overcome the above difficulties, in the present invention, in addition to the plurality of separate and separated pressing parts 21 and the non-circular pressure contact protrusion 13 for reliably activating only a specific pressing part, the ejection opening by pressing the opener The positions of the pressing force applied to the stopper (pressing area) and the distances (34-A, B, C) from the position to the expected incision groove point at the most recent distance were differentiated. The point that should be set to the closest distance is, of course, the point 34-A closest to the edge of either mouth where the initial fracture occurs.

In the embodiment of the present invention to be described later, the first fracture occurs near the left mouth edge, and then the shear of the incision groove proceeds by tilting the opener until the sharp curve of the left mouth edge is completely returned (the left mouth tail is completely cut out). The first shear action was delayed while the right mouth remained firmly compressed. In addition, it is desirable to make a slight difference in the vertical gaps 35-A, B, and C between the pressing portions and the corresponding pressing regions.

With the above technical solution, the sharp curve of the left corner of the mouth is technically perfect, and once the incision is completed, the remaining right half of the incision is made smoothly even with a small force. Only the same simple can opener tilting operation can reliably open a can discharge stopper having a wide transverse cutting width of a smiling mouth.

According to the present invention, the smile can be practically delivered to the consumer when the can is opened and the beverage can be drinked, and it can relieve fatigue and frustration, invigorate and awaken love for the modern people living in the dry and present age. In other words, there is an excellent emotional stimulus effect that was not found in conventional cans that were only a large amount of industrial products.

In addition, due to the unique design of the maximum incision width of the present invention, the position of the opener and the pressure contact projection is drawn toward the beverage outlet compared to the conventional can based on the same discharge area, and the unique eye-shaped protrusion design of the present invention The top of the can on the side of the opener handle is lowered while satisfying the specified top strength. This has the additional effect that the opener handle can be placed far away from the perimeter of the can and placed high, making it easier to hold and pull when opening the can.

In order to represent the main technical features of the present invention in more detail with reference to an embodiment of the present invention included in the drawings will be described in more detail below.

For reference, in the following embodiments, components including specific terms and structures in which they are combined do not limit the technical concept inherent in the present invention.

1 to 5 show the outer appearance of the can of the present invention.

In the drawing, the discharge stopper 11 is disposed on one side of the upper surface of the can 10 and has at least one row of discharge mouth openings 14 having a smiley mouth shape. In the present invention, the same basic structure was followed.) The discharge stopper 11 defined by the shape of the discharge hole cutout groove 14 and the discharge hole 30 defined by the shape of the discharge hole stopper 11 have a horizontal width. At least half of the diameter of the can top surface 10 is designed to have a maximum incision width and the longitudinal length is much smaller. Of course, the main technical concern of the present invention is whether the cutting groove shear occurs smoothly in the horizontal width direction (about 9 o'clock to 6 o'clock) in the direction of the maximum incision width.

On the other hand, the can top surface structure understood from the figure has a high side where the discharge port stopper 11 is located, and a side where the handle part of the opener 20 is located is low. This is due to the

protrusions

15 and 16 corresponding to the smiling eyes and eyebrows, but there may be reasons for sharpening the protrusions, but the

protrusions

15 and 16 supplement the insufficient strength of the upper half. This is also because the strength reinforcement design is not necessary. Looking at the drawings it can be seen that the semi-circular top reinforcing rib 17 corresponding to the smiley mouth is formed only on the side where the discharge plug 11 is located. Accordingly, the gap between the surface on which the eye protrusions 15 are formed and the opener 20 may be larger than the gap between the surface on which the discharge stopper 11 is formed and the opener 20. Thanks to the horizontal position of the opener 20 descending from the top of the can border and the vertical position of the opener floating higher from the bottom, the finger can be inserted more easily.

Non-circular (long oval in the horizontal direction in the drawing) to prevent the opener 20 to rotate in a direction parallel to the can top surface 10, the pressing projection 13 to maximize the lever operation In order to be disposed as close as possible to the discharge port cut groove 14, the discharge hole cut groove 14 of the present invention has a much lower and wider shape than the conventional narrow and long cut groove, as a result, the pressure contact projection 13 is the upper surface of the can ( It is arranged to be biased toward the discharge outlet stopper 11 is located from the center of the center 10). This is the same as that of a conventional can that naturally achieves a structure that cannot be made because of the vertical length of the discharge port. In other words, an opener having a conventional handle length means that the biased position of the present indentation makes it easier to insert a finger, or a opener with a longer handle length may be employed.

On the other hand, the outlet plug 11 is further formed with a reduced smiley mouth plug reinforcing rib 12 corresponding to the smiley mouth shape of the discharge hole incision groove (14). For reference, as shown in the drawing, the discharge port cutout groove 14 is actually cut only in the outer line as in a normal can, and the inner line is notched in the groove, but smoothly proceeds the shear of the outer real cut groove and discharge plug It serves to delay the sinking of (11).

6 to 8 are top plan views illustrating in detail how the incision of the outlet plug 11 proceeds when opening the present invention, and illustrates the essential functions of the present invention.

First, in the drawing, a plurality of pressing parts 21 are formed on the lower surface of the opener 20 (the surface contacting the discharge plug 11) separately arranged in the maximum cutting width direction. The pressing parts 21 are sufficiently moldable by slightly changing the radius of curvature or placing a recess in the mold when bending the opener rim in the press process, which is a conventional opener manufacturing process.

The pressing parts 21 are 21-A, 21-B, 21-C from the left in the order in which the pressing action is started first with the opening of the opener, and the pressing area is located at a position corresponding to the pressing parts on the discharge stopper 11. (33-A, 33-B, 33-C) are formed virtually.

At this time, in order to satisfy the core contents of the present invention, that is, the front end of the discharge hole cutting groove is smoothly started and propagated sequentially, so as not to cause a tearing phenomenon or the like, between the pressing areas 33 and the discharge hole cutting groove 14. The horizontal gaps 34 need to be of different sizes.

That is, referring to FIG. 5, the 33-A point and the incision groove 14, which are the first strongly pressed portions, are closest to each other. Therefore, it can be most easily broken and the break point 32 first occurs at the point indicated by the horizontal gap 34-A and propagates from side to side. At this time, the size of the horizontal gaps 34-A, B and C is 34-A the smallest, followed by 34-B and finally 34-C the largest. Therefore, until the left edge of the smiley mouth is completely cut out (see Fig. 6), the right edge is delayed in addition to the incision, and as a result, the sharp curve section of the left mouth edge, which is the most difficult part of the present invention, is first performed without failure. Can be cut out.

9 is a cross-sectional side view of the can of the present invention, illustrating the vertical gaps 35-A, B and C between the pressing portions 21 -A, B and C and the pressing regions 33 -A, B and C, respectively. Doing. Similar to the above-described concept of 34-A, B, and C, the vertical gap 35-A between the pressing region 33-A and the pressing portion 21-A corresponding to the nearest horizontal gap 34-A is the smallest. In other words, the vertical gap 35-C between the pressing area 33-C corresponding to the largest horizontal gap 34-C and the pressing part 21-C corresponding to the pressing area 33-C. This means the biggest. Therefore, when tilting the opener, the left mouth edge point closest to the incision groove 14 first touches, and the right mouth edge point farthest to the incision groove 14 touches the last. The conventional can-opening structure as understood from FIG. 10 differs greatly from the present invention only by changing the order of the points at which the conventional opener rim substantially presses the discharge port plug, except for the horizontal and vertical separated pressing gaps presented in the present invention. Not really. However, in the process of performing such continuous sequential pressing, the opener is not simply tilted forward but rotates counterclockwise as well as tilting. In other words, the outlet plug is also cut in a counterclockwise direction in a counterclockwise direction in accordance with the rotational direction of the opener, and this incision structure can properly incision a low and wide half-moon discharge plug with a maximum incision width of more than 50% of the diameter of the top surface of the can. (As described earlier, the incision proceeds a little while the left edge is not pulled back, or the opener is inclined horizontally in a clockwise direction, and the incision line of the outlet stopper does not move forward in the counterclockwise direction.) .) In the present invention, the above phenomenon does not occur in the opener by the coupling structure of the pressure contact protrusion formed in the anti-rotation type, horizontal transverse tilt prevention type and accordingly the incision as long as the horizontal long incision groove does not stagnate or retreat backward It can be done.

While the embodiments of the present invention have been described in detail with reference to the drawings, the technical idea of the present invention is not limited to the above-described embodiments.

In other words, those of ordinary skill in the art to which the present invention pertains can utilize the technical spirit contained in the specification and the drawings of the present invention, and, if necessary, simple modifications that are not included in the specification and drawings of the present invention, and A simple extension example may be further implemented, but this is also obviously included in the scope of the technical idea uniquely possessed by the present invention.

Although the present invention has been described in the description and drawings to be optimized for a beverage can made of a cold rolled aluminum sheet of a normal standard, the technical features described in the claims of the present invention as it is applied to the position of the opening portion of the presser or discharge opening Of course, if the initial breaking position, the shear propagation direction, etc. are properly adjusted, it is of course applicable to non-beverage cans or steel cans.
