Description

Technical Field

[0001] The utility model relates to the technical field of sealing structures, in particular to a sealed tear-off lid. Background Art

[0002] A tear-off lid is a new type of bottle cap. The characteristics of this kind of bottle cap are that it can be opened without special tools, the structure is relatively simple, and it is also relatively easy to manufacture. The tear-off lid structure is widely used in the packaging of disposable products, such as: food packaging, personal care products, small gift packaging, etc. The design advantages of the tear-off lid structure are as follows: 1. Convenient and fast. The design of the tear-off lid structure enables users to quickly open the package, improving the convenience of use. 2. Safe and hygienic. Since no additional tools are required, the tear-off lid structure reduces the risk of cross-contamination, especially suitable for the packaging of food and personal care products. 3. Protect the contents. The tear-off lid structure can keep the contents sealed without completely opening the package, which helps to extend the freshness and shelf life of the product. 4. Tamper-proof design. The tear-off lid structure usually has the characteristics of being disposable. Once opened, it cannot be restored to its original state, which helps to prevent the product from being repackaged or tampered with by unauthorized third parties.

[0003] For example, the quick tear-off lid structure for the one-time essential oil sealing disclosed in the Chinese patent document (Publication No.: CN215045337U). Although this utility model achieves the purpose of simple tearing and good effect by the cooperation of structures such as a snap ring, a flip cover and a tear strip, the whole tear strip adopts a flat structure, which is different from the traditional cylindrical structure. The tear strip and the snap ring, flip cover adopt an adhesive form. Subsequently, during use, workers can cooperate with an elastic pull ring to tear open the tear strip, and can also use the elastic pull ring to pull and open the protruding block. At this time, the whole flip cover is smoothly torn open, and the subsequent use of essential oil is very simple and easy, and the overall operation is also very easy and smooth.

[0004] However, the snap ring and the bottle body are directly sleeved through threads without a tamper-proof device. It is easy to separate the snap ring, flip cover and protective cover from the bottle body, then replace the genuine essential oil in the bottle with fake essential oil, reset the sealing film, and then thread the snap ring, flip cover and protective cover onto the bottle body. From the outside, it cannot be found that it is a fake product. Moreover, when the essential oil bottle is placed upside down accidentally during handling or storage, under the gravity of the essential oil, the surface of the sealing film will bulge, touch the elastic block, and thus be punctured by the rubber spikes on the elastic block, resulting in sealing failure and essential oil leakage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following will describe in detail the embodiments of the technical solutions of the present invention with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0025] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application shall have the ordinary meanings understood by those skilled in the art to which this utility model belongs.

[0026] Referring to Figure 1-6 , a sealed tear-off cap, comprising a bottle body 1 and a bottle cap 2, characterized in that: the bottle body 1 includes a bottle body 101 and a bottle mouth 102, the inner wall of the bottle cap 2 contacts the outer surface of the bottle mouth 102, an annular limiting groove 3 is provided on the outer surface of the bottle mouth 102, an annular sealing groove 4 is provided on the outer surface of the bottle mouth 102 of the bottle body 1, a sealing film 5 is fixedly installed on the upper surface of the bottle mouth 102, after the bottle body 1 is filled with essential oil, the sealing film 5 performs the first layer of sealing on the essential oil in the bottle, a sealing strip 6 is fixedly connected to the inner wall of the bottle cap 2, the outer surface of the sealing strip 6 contacts the inner wall of the annular sealing groove 4, and the sealing strip 6 and the annular sealing groove 4 cooperate with each other to perform secondary sealing on the essential oil in the bottle, and the inner top wall of the bottle cap 2 is fixedly connected with first springs 7 distributed in an annular array;

[0027] One end of each of the plurality of first springs 7 is fixedly connected with a sealing pressing plate 9, the outer surface of the sealing pressing plate 9 is slidably sleeved with the inner wall of the bottle cap 2, and the lower surface of the sealing pressing plate 9 contacts the upper surface of the sealing film 5. After the bottle cap 2 is installed, the reverse force generated by the contraction of the first springs 7 presses the sealing pressing plate 9, so that the sealing pressing plate 9 protects the sealing film 5 and enhances the sealing performance of the sealing film 5.

[0028] Further, a conical block 10 is fixedly connected to the upper surface of the bottle cap 2, and an annular protection block 11 is fixedly connected to the upper surface of the bottle cap 2. When the essential oil needs to be used, the bottle cap 2 is flipped and the conical block 10 is used to pierce the sealing film.

[0029] Further, the lower surface of the bottle cap 2 is fixedly connected with first connecting columns 12 distributed in an annular array, and the lower surfaces of the plurality of first connecting columns 12 are fixedly connected with an annular connecting strip 13. The first connecting columns 12 connect the bottle cap 2 and the annular connecting strip 13.

[0030] Further, the two end surfaces of the annular connecting strip 13 contact each other, and a connecting block 14 is fixedly connected to the outer surface of one end of the annular connecting strip 13. The two end surfaces of the annular connecting strip 13 contact to form a ring.

[0031] Further, a pull ring 15 is fixedly connected to one side surface of the connecting block 14, and second connecting columns 16 distributed in an annular array are fixedly connected to the lower surface of the annular connecting strip 13. When the bottle cap needs to be opened, the pull ring 15 is grasped and pulled, so that the connection between the annular connecting strip 13 and the first connecting columns 12 and the second connecting columns 16 is separated.

[0032] Furthermore, fixed clamping rings 17 are fixedly connected to the lower surfaces of the plurality of second connecting columns 16. Installation grooves 18 distributed in an annular array are formed in the inner walls of the fixed clamping rings 17. A second spring 19 is fixedly connected to one inner wall of the installation groove 18. The purpose of arranging the fixed clamping rings 17 is to fix the bottle cap 2 on the outer surface of the bottle mouth 102.

[0033] Furthermore, one end of the second spring 19 is fixedly connected to a limiting block 8. An extrusion inclined surface 20 is arranged at one end of the limiting block 8. The upper surface of the limiting block 8 contacts the inner top wall of the annular limiting groove 3. The limiting block 8 and the annular limiting groove 3 cooperate with each other to limit the fixed clamping ring 17, thereby fixing the bottle cap 2 on the outer surface of the bottle mouth 102.

[0034] Through the arrangement of the fixed clamping ring, the bottle cap can be fixed on the outer surface of the bottle mouth. And it is very difficult to remove the bottle cap without damaging the connecting strip after the bottle cap is installed, preventing third parties from replacing genuine essential oils with fake essential oils. And the arrangement of the sealing pressing plate makes the sealing film not easily damaged and has better sealing performance.

[0035] Working principle: Step 1, after the bottle body 1 is filled with essential oil and the sealing film 5 at the bottle mouth 102 is sealed, move the bottle cap 2 downward along the direction of the bottle mouth 102. The bottle cap 2 drives the fixed clamping ring 17 to move downward through the first connecting column 12, the annular connecting strip 13 and the second connecting column 16. Since the surface of one side of the limiting block 8 close to the bottle mouth 102 is the extrusion inclined surface 20, it will not limit the downward movement of the bottle cap 2. At the same time, the bottle mouth 102 presses the limiting block 8, and the limiting block 8 drives the second spring 19 to contract. When the sealing film 5 contacts the sealing pressing plate 9, the sealing pressing plate 9 is blocked and does not move downward anymore. The bottle cap 2 continues to move downward and drives the first spring 7 to contract. The reverse pressure of the contraction of the first spring 7 makes the sealing pressing plate 9 press the sealing film 5, protecting the sealing film 5 and strengthening the sealing performance at the same time. Until the annular limiting groove 3 of the bottle mouth 102 is flush with the installation groove 18 of the fixed clamping ring 17, the bottle mouth 102 no longer presses the limiting block 8, the second spring 19 resets, and the upper surface of the limiting block 8 contacts the inner top wall of the annular limiting groove 3 to limit the movement of the bottle cap 2. At this time, the outer surface of the sealing strip 6 contacts the inner wall of the annular sealing groove 4 to perform a second-level sealing protection on the essential oil in the bottle body 1. At this time, the installation of the bottle cap 2 is completed.

[0036] Step 2, when the essential oil inside the bottle body 1 needs to be used, hold the pull ring 15 and pull it to separate the connection between the annular connecting strip 13 and the first connecting column 12 and the second connecting column 16. At this time, there is no connection relationship between the fixed clamping ring 17 and the bottle cap 2, and the bottle cap 2 can be separated from the bottle body 1. Then turn the bottle cap 2 over and move the conical block 10 towards the sealing film 5 to pierce the sealing film 5. At this time, the essential oil in the bottle body 1 can be used.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
