Description

Technical Field

[0001] The present invention relates to an inner bottle cap, and more particularly, to a foldable pull tab cap. Background Art

[0002] In various cream products in daily chemical skin care products, various different packaging materials are generally used to ensure the airtightness of the products and prevent the products from sticking to the inner side of the cap. These include the use of aluminum foil, self-adhesive film, and plastic pull tab caps made by injection molding, etc. These existing technologies bring great inconvenience to consumers in current products: Aluminum foil and self-adhesive film need to be torn off or partially torn off during the first use, but the torn-off or partially torn-off parts can no longer protect the products in the can; Plastic pull tab caps are both easy to lose and easy to contaminate the products during each use, and the products in the can are prone to overflow during the process of taking out and putting back, making the inside and outside of the can not remain clean. The present patented technology solves various inconveniences encountered by current consumers, enabling consumers to have both protection performance and easy operation when using various canned products.

[0023] Furthermore, a foldable handle cover provided by the present invention is further characterized in that:

[0024] Both ends of the folding line have notches.

[0025] Furthermore, a foldable handle cover provided by the present invention is further characterized in that:

[0026] The lower surface of the folding part has a restoring handle.

[0027] Functions and effects of the present invention:

[0028] The foldable handle cover provided by the present invention is easy to manufacture, and the product can be realized by using a general multi-cavity injection molding process.

[0029] The foldable handle cover provided by the present invention can achieve the effect of ensuring the airtightness of the product as well as the currently used handle cover. At the same time, the foldable handle cover provided by the present invention can also effectively prevent the product from sticking to the top cover.

[0030] The foldable handle cover provided by the present invention can be folded during use. There is no need to take out the entire handle cover. It can be used by folding. The method of digging out the product in the can after folding is also extremely convenient. After use, it can be selectively reset and covered.

[0031] Since the foldable handle cover provided by the present invention does not need to be completely taken out during use, it is not easy to be lost or contaminated. In addition, there is no need for the process of covering and taking out back and forth, which is convenient to use and will not cause confusion. Therefore, the user experience is better, and the inner cover will not be discarded by the user due to the frequent operation of taking out and covering back, thus avoiding the problem of deteriorating product effect.

[0032] In addition, since the foldable handle cover provided by the present invention does not need to be taken out and put back during use, it prevents the problem of spillage of the product in the can when the bottle is full, so that the inside and outside of the can can be kept clean. At the same time, the inner cover of the bottle will not be repeatedly contaminated by the product during the process of being put back frequently. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] This embodiment provides a foldable handle cover, which is located inside a bottle body such as a cosmetic bottle. When the bottle cap is opened, it is used to seal the contents in the bottle, ensuring its quality and preventing secondary contamination.

[0039] As Figure 1 shown, the foldable handle cover includes a pull cover body;

[0040] The pull cover body is a circular cover in this embodiment, which is manufactured by injection molding and consists of a fixed part 110 and a folding part 120;

[0041] The fixed part 110 and the folding part 120 are connected by a folding line 130, and the folding line 130 has a thickness of 0.1 - 0.4 mm, which is 0.1 / 10 - 5 / 10 of the thickness of the fixed part;

[0042] Both ends of the folding line have a notch design, which can facilitate the folding of the folding part;

[0043] The width D1 of the fixing portion 110 is slightly larger than the width D2 of the folding portion 120 ;

[0044] D1=D2+0.2-1mm;

[0045] like Figure 2 As shown, the folding portion 120 starts from the folding position and has an upward angle α of 1-5° relative to the fixing portion. The size of the angle α is determined according to the diameter of the entire handle cover.

[0046] The upper surface of the folding portion 120 further has a handle piece 121, which is raised relative to the surface of the folding portion. During use, the folding portion can be lifted by pulling up the handle piece.

[0047] In addition, the entire circumference of the handle cover has a raised edge;

[0048] The edge has an outward flange at its distal end;

[0049] The height of the folding portion edge 122 is slightly lower than the height of the fixing portion edge 112;

[0050] Generally speaking, the height H2 of the folded edge 122 is 2 to 6 mm;

[0051] The height H1 of the fixing portion edge 112 is 3 to 8 mm;

[0052] The most preferred height difference is H1=H2+0.5~0.7mm;

[0053] like Figure 3 As shown, after all the cosmetics are poured into the bottle body 10, the handle cover 100 is installed at the bottle mouth;

[0054] The flange prevents it from falling into the cosmetics;

[0055] During use, if Figure 4 As shown, the folding portion is turned along the folding line toward the fixed portion so as to be folded in half, with the folding portion stacked on top of the fixed portion and the handle piece being flattened;

[0056] After use, the folding portion can be popped out by lightly flicking the edge of the fixed portion to restore the original shape.

[0057] Of course, for the convenience of reset, such as Figure 5 In the modified example shown, a handle piece 123 is also provided on the lower surface of the folding portion 120. After use, the handle piece 123 is pulled up to pull up the entire folding portion 120 to restore it.
