Description

Easy-to-open can lid

Technical Field

The utility model belongs to the technical field of food processing. Specifically, the utility model relates to a pop-top can lid.

Background

The following description is made of the related art of the present invention, but these descriptions do not necessarily constitute the prior art of the present invention.

The development of canned foods has gone from tin cans made from glass bottles plus cork to tin plated tin cans. Since the advent of the iron can, the iron can is popular with consumers because of its advantages of convenient carrying and easy storage. On the basis of considering the cost, the tinplate is always developed towards the thinning direction. Generally, a pull ring is arranged on the lid body, but because the iron sheet of the lid body is too thin, burrs are generated at the broken part when the lid is pulled by the pull ring, so that a user is very easily scratched when the can lid is pulled. In addition, if the surface of the cover is smooth and straight, the risk of explosion of the tank can also exist, because the air pressure exists in the tank, and when the accumulated air pressure is high, the tank can easily explode. In addition, the pull tab of the existing commercially available can end is generally disposed to be closely attached to the can end, is not easily pulled up, and is easily broken.

In recent years, people have been centered around how to open and develop new can lids more easily. However, some can lids developed are too complex in structure and use more materials, resulting in waste of raw materials. There are also some can lids designed to make the interior space of the can body smaller.

CN215514898U discloses a design that utilizes two protrusions made on both sides of the tab to increase the gap between the tab and the iron sheet. However, the gap is still too small only by the arrangement of the convex point, so that the requirement of labor saving of operators is not met, and the can cover is still not easy to pull up.

CN204548750U discloses an improved can lid, wherein the force application point is a line during the opening process, so that although it is labor-saving when pulling, it is easy to break during pulling, and the raised strip can cause the contamination of the food inside the can when the lid body is pulled off.

Therefore, the can cover which is convenient, labor-saving, easy to open, capable of avoiding scratching operators, simple in structure, low in processing cost and incapable of causing waste of raw materials is always absent in the prior art.

As shown in fig. 1 to 3, a can lid of a pop-top type according to an embodiment of the present invention includes a lid body 2 for fixedly coupling to an upper portion 1 of a can body to seal the inside of the can body. When the lid body 2 is fixedly attached to the can body upper portion 1 to seal the inside of the can body, a pre-engraved line 3 is formed between the lid body 2 and the can body upper portion 1. When the lid body 2 is opened, it is separated from the can body upper part 1 along the pre-scored line 3.

As an embodiment, as also shown in fig. 1-3, the cap body 2 includes a first member 21 and a second member 22. The second part 22 is fixedly connected to the first part 21 and comprises a tab portion 221 for opening the can lid. Preferably, the first member 21 is provided with a large groove 211 similar to a water drop shape. Preferably, a small groove 212 is also provided on the first part 21; the shape of the small recesses 212 may be oval, four or six in number, etc., arranged in a symmetrical manner, four being shown. The purpose of providing the large recess 211 and the small recess 212 in the first member 21 is: reducing the air pressure in the tank. This is because inside the jar interior food is not full of whole can body, can leave some gaps, can produce gaseous release in food transportation, increases the recess and will reduce the gap of can lid and jar interior food, reduces the gas volume that produces, can not explode the jar. In addition, the groove also plays a role in buffering expansion caused by heat and contraction caused by cold. Therefore, the large groove and the small groove can further reduce the resistance for opening the can lid, and the can lid can be opened more conveniently and more laborsavingly.

In one embodiment, the edge of the first member 21 is provided with a ring of inwardly turned circular protrusions (not shown). The first part 21 is fixedly connected to the can body upper part 1 via the inwardly turned round projection. Therefore, when the can cover is opened, the round protruding part serves as a breaking part, so that a sharp edge part cannot be generated, the hand of an operator is prevented from being scratched, and the safety of opening the can cover is improved. Meanwhile, the connecting area of the circular protruding part which is turned inwards and the upper part 1 of the can body is not increased, so that the difficulty of pulling the can cover is not increased, and the situation of labor waste is not caused.

As also shown in fig. 1 to 3, the first member 21 is provided at the center thereof with a recess 213, and preferably, the recess 213 may be recessed downward in a stepped shape so that a large gap is formed between one end of the second member 22 fixed to the first member 21 and the first member 21, thereby facilitating the operation of the second member 22 by a person. For example, as an example, one end of the second part 22 has a pull ring part 221, whereby the position of the pull ring part 221 corresponds to the position of the recess 213 of the first part 21, as shown in fig. 1, whereby the recess 213 leaves a large clearance between the pull ring part 221 and the surface of the first part 21, so that a person can pull the lid body with a finger protruding into the pull ring. Can lid among the prior art usually is its pulling part, for example the pull ring, and does not set up the space alone between the lid body, namely, on the lid body was arranged in to the pulling part level, at this moment, people wanted to stretch into the pull ring with the finger, need very expendingly prize the pull ring, make it and the upper surface of lid body between appear the space, can stretch into the pull ring with the finger that is used for pulling can lid. Thus, the provision of the recess 213 on the first part 21 facilitates the insertion of a finger into the pull ring by an operator compared to the prior art.

As an embodiment, the tab portion 221 of the second part 22 is preferably upwardly inclined with respect to the upper surface of the first part 21 by an angle in the range of 20 ° to 30 °. Practice proves that when the included angle between the pulling finger and the upper surface of the can cover is 40-50 degrees, the finger is more labor-saving when pulling. Because the concave part 213 is arranged below the tail part of the pull ring, the inclination angle of the concave part 213 is about 20 degrees, the inclination included angle of the pull ring part is selected to be 20 degrees to 30 degrees, and when a finger extends into the pull ring, the included angle with the plane of the can cover is the sum of two included angles, namely, 40 degrees to 50 degrees. Therefore, the fingers of an operator can extend into the pull ring to perform the cover pulling operation conveniently. As an example, the end of the second part 22 opposite to the tab portion 221 has a pointed portion 222 for piercing down through the lid body 2 at a position close to the pre-scored line 3 or directly through the pre-scored line 3 when opening the can lid, to thereby open the can lid along the pre-scored line 3.

As an embodiment, it is preferable that the second member 22 further includes a positioning post 223 for fixing the end of the second member 22 with the pointed portion 222 to the first member 21. Locating posts 230 are shown in fig. 1 and 3. It should be noted that the purpose of the positioning post 230 is not only to fix the second member 22 to the first member 21, but the positioning post 230 also has an auxiliary function of opening the can lid. Specifically, when the operator's finger is inserted into the tab, the positioning post 230 can serve to support the knuckle at the rear end of the finger, i.e., the second knuckle of the finger inserted into the tab can abut against the positioning post 230, thereby making it easier to pull up the can lid using the principle of leverage.

Preferably, the tab tail end 2211 of the tab portion 221 of the second part 22 has a thickness greater than the tab front end 2213, by way of example, the tab tail end 2211 may have a thickness 4-6mm, preferably 5mm, greater than the tab front end 2213. Therefore, when an operator stretches fingers into the pull ring to pull the can cover, the pull contact area between the fingers and the pull ring is increased, the fingers cannot be pressed, acting force is applied more easily, and the can cover is in accordance with ergonomics. Further, it is preferable that the tab tail end 2211 of the tab 221 is designed to have an inward concave curvature, that is, the tab tail end 2211 has an inward concave tail end recess 2212, as shown in fig. 2, when the fingers of the operator are inserted into the tab, the fingers abut against the curvature, which further makes the operator feel comfortable, reduces the pressure when the fingers pull the cap body, and is ergonomic.

Preferably, the first part 21 is provided with a clearance notch 214 corresponding to the end of the pull ring 221 having the spike 222, and the clearance notch corresponds to the spike 222, so that the spike 222 can pierce the cap body more easily. As an example, the position of the relief notch 214 may be set near the circumference of the pre-engraved line 3 formed when the lid body 2 is fixedly attached to the can body upper portion 1 for facilitating the pulling apart of the lid body along the pre-engraved line 3 after piercing the lid body. As an example, the clearance gap 214 is a concave gap, and the tip of the tip 222 is vertically downward and points to the clearance gap, so that when the operator pulls the pull ring, the tip can pierce the clearance gap more easily, thereby saving labor and facilitating opening the can lid. As a further example, the clearance gap 214 may be provided on the bottom of the first member 21, and the position corresponding to the pointed portion 222 is thinner due to the clearance gap, so that the pointed portion 222 is easier to pierce, and the cover body is easier to pull up.

Preferably, the second part 22 is provided in a shape similar to a gourd, as shown in fig. 3, which allows for a reduction in material and an increase in aesthetics compared to other shapes of the prior art, such as a fan shape.

According to the utility model discloses a pop-top can lid sets up 20-30 upwards to slope for the upper surface of first part through the pull ring portion with the second part to and set up the concave part through the position department corresponding with pull ring portion on with the first part for the operator stretches into the pull ring with the finger more easily and draws the lid operation. In addition, through set up on first part keep away the position breach and make this keep away the position breach and be close to the pre-scored line annex, with the individual sharp form portion of second portion corresponding to keep away the position breach to pierce through the lid body through sharp form portion more easily, thereby pull open the can lid along the pre-scored line, reduce the operating resistance. Furthermore, the tail end concave part is arranged on the tail end of the pull ring part, and the thickness of the tail end of the pull ring is larger than that of the front end of the pull ring, so that an operator can pull open the can cover more comfortably in a labor-saving manner, and the ergonomics is met.

Furthermore, according to the utility model discloses an easy-to-draw type can lid sets up the circular protruding portion that the round was inwards rolled up through the limit portion at first part to through this circular protruding portion and can body upper portion fixed connection, can realize when opening the can lid, circular protruding portion is as disconnection department, thereby can not produce sharp limit portion, avoids fish tail operating personnel's finger from this, has increased the security of opening the can lid.
