Description

Technical Field

[0001] The utility model belongs to the field of food packaging and relates to a container design, in particular to a disposable easy-pull can design, which has the functions of convenient opening and storage. Background Art

[0002] In today's market, disposable cans have become a common packaging container, widely used in food, beverages and other liquid products. However, in some specific cases, the use of traditional cans is not convenient, especially for people with impaired or disabled hand motor ability, children and people with short or soft nails.

[0003] People with impaired or disabled hand motor skills, children, and people with short or soft nails may encounter the following problems in their daily lives:

[0004] Difficult to open: Considering that the above-mentioned people often encounter inconvenience when opening cans, and the traditional can design is also prone to cause hand injuries, it requires strong pulling or the use of additional tools to open.

[0005] Hygiene issues: People are paying more and more attention to hygiene and hope to reduce the frequency of contact with objects, such as paper towels used to wipe the top of cans.

[0006] Storage problems: Currently, cans of the same specifications on the market have storage problems, such as being difficult to stack stably. Utility Model Content

[0007] In view of the above problems, the utility model proposes a disposable can for people with impaired hand motor skills or disabilities, children, and people with short or soft nails. Through the solid pull ring and easy opening design, it can solve the inconvenience of using traditional cans and provide a more hygienic user experience.

[0008] The structure of the convenient-opening aluminum can designed based on ergonomics and sanitation and safety is as follows:

[0009] The top and bottom surfaces of the can body have protrusions coaxial with the can body on the circumference. A C-shaped notch is designed on the side of the top surface of the can body, and the opening of the C-shaped notch faces the center of the top surface of the can body. Among them, the protrusion on the circumference of the top surface of the can body is an arc protrusion, and the arc protrusion is a height-gradient protrusion, and the opening positions of the two opposite ends are located at the C-shaped notch. At the same time, the height of the protrusion gradually increases along the circumference in the opposite direction from the two opposite ends, and the highest point is located on the opposite side of the C-shaped notch area.

[0010] The center of the top surface of the can body is connected to the buckle by rivets. One end of the buckle is a long end, which is located at one end of the arc protrusion, and the end is located between the two ends of the arc protrusion, and the end is located outside the arc protrusion.

[0011] Therefore, when in use, the pull buckle can be rotated along the arc protrusion to gradually raise one end of the pull buckle and form a gap between the top surface of the can. At this time, the pull buckle is pulled upward through the gap, and the other side of the pull buckle presses down the scored area on the top surface of the can to open the can.

[0012] The advantages of the utility model are:

[0013] 1. The disposable aluminum can of the utility model is easy to open and meets the needs of people with impaired hand movement ability or disabilities, children and people with short or soft nails;

[0014] 2. The disposable aluminum can of the utility model can provide users with a more hygienic use experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model is a disposable aluminum can, which is improved on the basis of the existing aluminum can, and comprises a can body 1, a solid pull buckle 2, an arc protrusion 3 and a circular protrusion 4. Figure 1 , Figure 2 shown.

[0024] The can body 1 is a conventional cylindrical structure, and the top and bottom surfaces are provided with protrusions coaxial with the can body 1 in the circumferential direction. The top surface structure of the can body 1 is the same as that of the existing can body, that is, a C-shaped notch is designed near the side of the top surface of the can, and the opening of the C-shaped notch is directly opposite to the center of the top surface of the can body 1. The center of the top surface of the can body 1 is connected to the pull buckle by a rivet 5. The area surrounded by the C-shaped notch is an opening 6, which can be opened in cooperation with the pull buckle. Figure 3 shown.

[0025] Based on the above structure, in the utility model, the circumferential protrusion on the top surface of the can body 1 is designed to be an arc protrusion 3; at the same time, the arc protrusion 3 is designed to be a height-gradient protrusion, and the pull buckle 2 protrudes between its two opposite ends, and the opening position is located at the C-shaped notch. At the same time, the protrusion height gradually increases along the circumference in the opposite direction from the two opposite ends until it reaches the designed maximum height. The highest point is located on the opposite side of the notched area, and the angle between the highest point and the center line of the top surface of the can body 1 and the top surface of the can body 1 is 20 degrees. The above-mentioned arc protrusion 3 has a diameter of 5.4 cm, and the radial spacing between the top of the arc protrusion 3 and the outer wall of the can body 1 is 0.75 cm. Figure 5 shown.

[0026] In the utility model, the buckle is designed to be a solid buckle 2, which is a solid sheet structure with an approximately elliptical shape and recessed inward on both sides, and the length of the rear part of the recessed position is smaller than the length of the front part of the recessed position, so that the rear and front parts of the recessed position are the short end and the long end of the solid buckle 2 respectively. On the solid pull tab 2 of the above structure, the middle part between the long end and the short end is connected to the top surface of the can body 1 by a rivet 5, fixing the axial position of the solid pull tab 2 on the can body 1; and after the solid pull tab 2 is connected to the can body 1, the solid pull tab 2 is located in the initial position; in this position, the solid pull tab 2 fits the top surface of the can body 1, and the long end of the solid pull tab blocks the notched area; at the same time, the long end of the solid pull tab 2 is located between the opposite ends of the upper arc protrusion 3, and the long end is located outside the arc protrusion 3, exceeding the arc protrusion 3 by about 0.2 cm in the circumferential direction; and the long end is also located inside the outer wall of the can body 1. The above solid pull tab 2 can block dust from the notched area in the initial state, which can reduce the degree of contamination of the can opening 6 accordingly.

[0027] To realize the stacking of the above structure cans, Figure 4 As shown, in the present invention, the circumferential protrusion on the bottom surface of the can body 1 is designed as a circular protrusion 4 with a notch. The circular protrusion 4 has a rectangular notch 401 on the circumference, and the width of the notch 401 is equal to the distance between the two opposite ends of the upper arc protrusion 3. Therefore, when two can bodies 1 are stacked, the solid pull buckle 2 is avoided through the rectangular notch 401.

[0028] When the disposable aluminum can of the utility model is in use, the long end of the solid pull tab 2 is rotated 180 degrees to one side along the arc protrusion on the top surface of the can body 1. Due to the gradual height design of the arc protrusion 3 at the upper end, the long end is gradually and passively raised during the rotation of the solid pull tab 2, so that a gap is generated between the long end and the top surface of the can body 1. At this time, the solid pull tab 2 can be pulled upward through the gap, and the short end of the solid pull tab 2 presses downward the open end of the area surrounded by the notch, so that the notch of the open end breaks and bends downward, thereby realizing the opening of the can body 1.

[0029] When storing the disposable aluminum cans of the utility model, the can bodies 1 are stacked and stored. When stacking, firstly, the opening 401 on the annular protrusion 4 on the bottom surface of the upper can body 1 is aligned with the solid pull button 2 of the lower can body 1; then the upper can body 1 is moved downward, so that the arc protrusion 3 on the top surface of the lower can body 1 is inserted into the annular protrusion 4 on the bottom surface of the upper can body 1, and at the same time, the long end of the solid pull button 2 is matched and embedded in the rectangular opening 401 on the annular protrusion 4 on the bottom surface of the upper can body 1, so as to realize the stacking and storage of the cans.

[0030] The disposable aluminum can of the utility model is more ergonomically designed, which can solve the inconvenience of using traditional cans; at the same time, it provides a more hygienic and practical container to meet the needs of people with impaired hand movement ability or disabilities, children and people with short or soft nails.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
