Description

Technical Field

[0001] This utility model relates to the field of packaging product technology, specifically a fingertip direct-access convenient easy-open lid. Background Technology

[0002] In the field of modern packaging technology, easy-open lids have become an indispensable packaging component in the food, beverage, and daily chemical industries due to their advantages such as convenient opening and excellent sealing. As consumer demands for product quality and user experience continue to rise, the design and manufacturing technology of easy-open lids is also constantly evolving. Today, consumers not only focus on the quality of the product itself but also have higher expectations for the practicality of the packaging.

[0003] Currently, most readily available easy-open lids typically consist of a roughly flat central lid with a raised, rolled edge. A specific opening tab area is created by machining serrations on the lid surface, and a pull ring is fixed in the corresponding position. A hollow rivet protrudes from one end of the tab and is riveted to the other end of the pull ring. The pull ring is positioned on the opposite side of the opening tab area formed by the serrations. While this structure fulfills the basic opening function, it presents some problems in actual use: the pull ring fits tightly to the lid, requiring the user to pry their fingernail into the gap between the ring and the lid, forcefully lift the ring, insert their fingertip, and finally pull the ring vertically to tear open the tab. However, this opening method is not user-friendly for children or women with manicured nails. Children's nails are fragile and difficult to apply force; women with manicured nails, due to the shape and material of their nails, are prone to slipping and difficulty applying force when prying open the pull ring, making it difficult to open the lid.

[0004] To address this issue, existing technologies attempt to punch a downward-facing groove at the end of the pull ring to create a gap between the pull ring and the cover. However, this improvement has limited effectiveness and cannot fundamentally solve the problem of the pull ring being difficult to pry open. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a convenient, easy-open fingertip-style pull-tab cover that enhances convenience while maintaining the original function of the pull tab, thereby increasing product visibility and brand influence. To this end, the technical solution adopted by this utility model is as follows:

[0006] A convenient, easy-open fingertip-access lid includes a circular lid surface with a large rolled edge that extends above it. A hollow rivet-attached pull ring is formed by an upward bulge at the center of the circular lid surface. Unlike existing technologies, the tail of the pull ring is pried up, with the tail end at least 4mm away from the circular lid surface.

[0007] Furthermore, the pull ring bends upward from the middle, and the angle α between the tangent at its tail end and the circular cover plane is 30 degrees.

[0008] Furthermore, the tail end of the pull ring does not exceed the height of the large rolled edge.

[0009] Furthermore, a recess is formed on the circular cover surface corresponding to the tail end of the pull ring, extending downwards, with a depth of 0.8-1.2 mm.

[0010] Furthermore, the outline of the recess is elliptical, with its major axis corresponding to the width direction of the pull ring.

[0011] Furthermore, the major axis of the ellipse is 15-20mm, and the minor axis is 8-10mm.

[0012] Furthermore, the small rolled edge at the tail end of the pull ring is flattened.

[0013] This utility model addresses the common challenges of using pull-tab lids in modern packaging products. It tackles the issue of traditional pull-tab lids having excessively tight fits between the pull ring and the lid, making them difficult for children and women with manicured nails to open, and existing improvement methods are ineffective. This innovative design proposes a fingertip-operated, convenient pull-tab lid. While retaining the basic function of the pull ring, this design innovatively pries up the end of the pull ring, ensuring a distance of at least 4mm between the end and the circular lid surface. This effectively solves the problem of the pull ring being difficult to pry open, significantly reducing the difficulty of opening the lid and greatly improving ease of use. This, in turn, helps enhance product market competitiveness and brand influence. Attached Figure Description

[0015] Figure 2 yes Figure 1 The front view.

[0016] Figure 3 This is a front view structural diagram of the pull ring of this utility model.

[0017] Figure 4 This is a schematic diagram of the structure of the tail end of this utility model. Detailed Implementation

[0018] See appendix Figure 1-4 A convenient, easy-open fingertip-access lid includes a circular lid 1 with a large rolled edge 11 extending above it. A hollow rivet 11 formed by the upward bulge at the center of the circular lid 1 is riveted to a pull ring 2. The tail of the pull ring 2 is pried up, with the tail end at least 4 mm away from the circular lid 1.

[0019] In traditional pull-tab designs, the pull ring fits tightly against the lid, leaving almost no space for fingers to slip in. Users must use their fingernails to pry open the lid, leveraging the nail to move the ring and further insert their fingers. However, this method can easily damage the nails of children with fragile nails or women with manicured nails, making it extremely difficult to pry open the pull ring.

[0020] In this embodiment, by prying up the tail of the pull ring 2, the tail end is at least 4mm away from the circular cover surface 1, creating a sufficiently spacious space between the tail end of the pull ring and the cover surface. This space can directly accommodate the user's fingertip, eliminating the need to use fingernails to pry open the pull ring. When the user needs to open the easy-open cover, they can directly place their fingertip into this space, utilizing the large contact area between the finger and the pull ring to more easily and stably pull up the pull ring, thereby greatly reducing the difficulty of opening and significantly improving the convenience of using the easy-open cover.

[0021] Detailed can opening process

[0022] Preparation stage: The user holds the can with the fingertip-operated easy-open lid and observes the position of the pull ring 2. At this time, it can be clearly seen that the tail of the pull ring 2 is pried up, forming a clear gap between it and the circular lid surface 1.

[0023] Fingertip insertion: The user naturally places their fingers in the gap between the end of the pull ring 2 and the circular cover 1, and easily inserts their fingertips into the space, ensuring full contact between the fingertips and the end of the pull ring 2. Since the end of the pull ring is at least 4mm away from the cover, it provides ample space for the fingertips, and the entire insertion process does not require forceful squeezing or prying.

[0024] Pulling up: Once the fingertips are in place, the user uses their finger muscles to smoothly pull the ring 2 upwards. Because the contact area between the fingertips and the ring is large, force can be applied evenly, making it easier and more stable to apply force compared to the traditional method of prying the ring up with fingernails.

[0025] Opening the tongue: As the pull ring 2 is pulled up, the tongue (located in the opening tongue area formed by the etched lines on the circular cap 1) which is riveted to the pull ring 2 by the hollow bubble 11 is subjected to the pulling force and is gradually torn open along the etched lines until the tongue is completely separated from the cap, thus completing the opening action of the can and allowing the user to enjoy the contents of the can.

[0026] In another preferred embodiment, the pull ring 2 bends upward from the middle, and the angle α between the tangent at its tail end and the plane of the circular cover 1 is 30 degrees. This design further optimizes the spatial form of the pull ring. The 30-degree angle makes the tail end of the pull ring and the cover surface form a more ergonomic angle, which facilitates fingertip insertion and makes it more in line with the user's hand force habits when pulling up the pull ring, reducing the force deviation when opening and further improving the ease and comfort of opening.

[0027] In another preferred embodiment, the tail end of the pull ring 2 does not exceed the height of the large rolled edge 11. This arrangement ensures the regularity and safety of the overall structure of the easy-open lid, avoids the pull ring tail end protruding too high, and prevents damage or scratches to users caused by collisions or snags of the pull ring tail end during packaging transportation, storage, or use. At the same time, it can also better fit the packaging container and maintain the uniformity of the packaging appearance.

[0028] In another preferred embodiment, a recess 12 is formed by extending downward from the circular cover 1 corresponding to the tail end of the pull ring 2, and the depth of the recess 12 is 0.8-1.2mm. The presence of the recess further increases the accommodating space between the tail end of the pull ring and the cover, providing a more defined placement area for the fingertip, enhancing the accuracy of finger positioning when the user opens the device, and the recess of a certain depth can effectively guide the direction of finger force, making the opening operation smoother.

[0029] In another preferred embodiment, the recess 12 has an elliptical outline, with its major axis corresponding to the width direction of the pull ring 2. The elliptical recess outline better matches the shape of the pull ring and the shape of the finger, and the major axis corresponding to the width direction of the pull ring can better fit the contact surface of the fingertip, increase the contact area between the finger and the inner wall of the recess, provide more stable friction when opening, and further improve the convenience and stability of opening.

[0030] In another preferred embodiment, the major axis of the ellipse is 15-20mm, and the minor axis is 8-10mm. The elliptical recess contour better matches the shape of the pull ring and the form of the finger. The major axis corresponds to the width direction of the pull ring, which can better fit the contact surface of the fingertip, increase the contact area between the finger and the inner wall of the recess, and provide more stable friction when opening, further improving the ease and stability of opening. By limiting the specific size of the recess, its size is adapted to the finger size of most users, ensuring that there is enough space for the fingertip, while preventing the recess from being too large and affecting the structural strength of the cover. This ensures both convenient opening and the overall structural reliability of the easy-open cover.

[0031] In another preferred embodiment, the small rolled edge 21 at the tail end of the pull ring 2 is flattened. Flattening the small rolled edge at the tail end significantly reduces its thickness in the vertical direction, further increasing the effective space between the pull ring tail end and the circular cap. This not only makes fingertip insertion easier and more unobstructed but also accommodates the placement needs of fingers of different sizes. Simultaneously, the flattened small rolled edge fits better with the recessed area of ​​the cap, making the point of force applied by the finger more concentrated when opening, allowing the pull ring to be pulled up with less force. This improves ease of opening while enhancing the stability and comfort of user operation.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
