Abstract
Description
Technical Field
[0001] This invention relates to the field of plastic bottle technology, and more particularly to a plastic bottle with an anti-slip concave interior. Background Technology
[0002] Plastic bottles, also known as plastic containers, are plastic containers formed by blow molding, extrusion blow molding, or injection molding using plastic molds. They are mainly used for single-use plastic packaging of liquids or solids. Plastic bottles are characterized by being unbreakable, inexpensive, highly transparent, and made from food-grade raw materials.
[0003] Chinese Patent Publication No. CN208439594U, published on January 29, 2019, discloses a plastic bottle, including a bottle cap and a bottle body. The bottle cap and the bottle body are screwed together by a threaded connection. The bottle body includes an upper bottle mouth, a middle bottle body, a lower handle, and a bottle bottom. The side wall of the handle is provided with an annular array of inner grooves, and the radial cross-section of the inner grooves is an isosceles triangle.
[0004] As with the aforementioned disclosed existing technologies concerning plastic bottles, plastic bottles are mostly composed of a cap, a bottle mouth, and a bottle body. During use, the airtightness of the bottle body is ensured by screwing the bottle mouth and cap together. However, in practice, some larger plastic bottles often cannot be emptied completely at once, so the cap needs to be screwed on tightly before being placed in the refrigerator for storage. However, the screw-on connection method often cannot guarantee the sealing effect of the bottle body, and external gases and bacteria can easily invade the inside of the bottle, thus causing contamination of the liquid inside the bottle. Therefore, there is an urgent need to propose corresponding plastic bottles with anti-slip concave interiors to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a plastic bottle with an anti-slip concave design in order to solve the above-mentioned problems.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A plastic bottle with an anti-slip concave design includes a bottle body, which includes a cap and a bottle body. A bottle mouth is fixedly installed on the top of the bottle body. The outer wall of the bottle mouth is screwed onto the cap. An anti-slip component is provided on the outer wall of the bottle body. The bottle body also includes a sealing mechanism for improving the sealing performance between the bottle mouth and the cap. The sealing mechanism includes a support ring, a convex ring, an outer ring, a connecting component for connecting the outer ring and the support ring, and a limiting component for axially limiting the support ring. The convex ring is fixedly connected to the bottle mouth. The outer ring is fixedly installed on the top of the convex ring. The support ring is sleeved on the outer wall of the cap, and the outer wall of the cap is provided with a constraint component for constraining the vertical position of the support ring. The outer wall of the support ring is integrally formed with a raised edge.
[0008] Preferably, the anti-slip component includes anti-slip textures on the outer wall of the bottle body, and an inward section is provided in the middle of the bottle body. The inner wall of the inward section is integrally formed with two sets of inner grooves, and the two sets of inner grooves are symmetrically distributed on both sides of the longitudinal end of the inward section.
[0009] Preferably, the constraint component includes a first limiting ring and a second limiting ring, both of which are fixedly installed on the outer wall of the bottle cap, and the first limiting ring and the second limiting ring are distributed on both sides of the vertical end of the support ring.
[0010] Preferably, the connecting assembly includes a plug ring and a sealing gasket, both of which are fixedly installed at the bottom of the support ring. An elastic sealing ring one and an elastic sealing ring two are fixedly installed on the inner wall of the outer ring, and the plug ring is inserted between the elastic sealing ring one and the elastic sealing ring two.
[0011] Preferably, the limiting component includes a connecting strap, the two ends of which are fixedly connected to the bottle cap and the outer wall of the bottle body, respectively, and the outer wall of the bottle body is provided with an elastic part for pressing down the connecting strap.
[0012] Preferably, the elastic part includes an elastic sheet, which is fixedly installed on the outer wall of the bottle body and pressed against the outside of the connecting strip.
[0013] Preferably, a connecting block is fixedly installed at the open end of the connecting strip, and a fixing seat is integrally formed on the outer wall of the bottle body. The connecting block is fixedly connected to the fixing seat by an adhesive.
[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0015] 1. In this application, rotating the bottle cap to screw it onto the bottle neck achieves initial sealing of the bottle. During this process, the support ring is pulled by the connecting belt, and the elastic sheet is pressed against the outside of the connecting belt, thus providing axial constraint for the support ring. This prevents the rotation of the bottle cap from having a significant impact on the support ring. Then, the support ring is pushed by the convex edge, causing the support ring to move downwards until the sealing gasket at the bottom of the support ring abuts against the top of the limiting ring two. At this point, the insert ring is inserted between the elastic sealing ring one and the elastic sealing ring two. The second ring fits tightly against the insert ring, ensuring its stable position. This allows the support ring, insert ring, and outer ring to form a closed chamber on the outside of the bottle mouth and cap, achieving a second seal on the bottle and further improving its sealing performance. The connecting strip not only limits the position of the cap but also allows it to coil after the cap separates from the bottle mouth. The cap and connecting strip can be held in place on the outside of the bottle by the elastic sheet, preventing the cap from detaching. Furthermore, multiple sets of bottles can be distinguished by changing the shape of the connecting strip when the cap and bottle mouth are screwed together.
[0016] 2. In this application, when holding the bottle, the operator's hand will combine with the anti-slip texture on the outside of the bottle, and the operator's fingers can combine with two sets of inner grooves. The gradient setting of the inner grooves and the bottle body, together with the anti-slip texture on the outside of the bottle body, can effectively improve the anti-slip effect of the plastic bottle, thereby improving the stability of the plastic bottle in use.

Detailed Implementation
[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see Figure 1-5 The present invention provides a technical solution:
[0026] A plastic bottle with an anti-slip concave inner surface includes a bottle body, which includes a cap 2 and a bottle body 1. A bottle mouth 9 is fixedly installed on the top of the bottle body 1. The outer wall of the bottle mouth 9 is screwed to the cap 2. An anti-slip component is provided on the outer wall of the bottle body 1. The bottle body 1 also includes a sealing mechanism for improving the sealing performance between the bottle mouth 9 and the cap 2. The sealing mechanism includes a support ring 7, a convex ring 16, an outer ring 15, a connecting component for connecting the outer ring 15 and the support ring 7, and a limiting component for axially limiting the support ring 7. The convex ring 16 is fixedly connected to the bottle mouth 9. The outer ring 15 is fixedly installed on the top of the convex ring 16. The support ring 7 is sleeved on the outer wall of the cap 2. The outer wall of the cap 2 is provided with a constraint component for constraining the vertical position of the support ring 7. The outer wall of the support ring 7 is integrally formed with a convex edge 11.
[0027] Rotate the bottle cap 2 to screw it onto the bottle opening 9, achieving initial sealing of the bottle. During this process, the support ring 7 is pulled by the connecting band 6, and the elastic sheet 5 is pressed against the outside of the connecting band 6, thus providing axial constraint for the support ring 7. This prevents the rotation of the bottle cap 2 from having a significant impact on the support ring 7. Then, the support ring 7 is pushed by the protruding edge 11, causing the support ring 7 to move the insert ring 12 downwards until the sealing gasket 13 at the bottom of the support ring 7 abuts against the top of the second limiting ring 14. At this point, the insert ring 12 is inserted between the first elastic sealing ring 17 and the second elastic sealing ring 18. The ring 7 fits tightly against the insert ring 12, ensuring the stability of the insert ring 12. This allows the support ring 7, insert ring 12, and outer ring 15 to form a closed chamber on the outside of the bottle mouth 9 and bottle cap 2, achieving a re-sealing of the bottle body and further improving the sealing performance of the bottle body. In addition, the connecting band 6 can not only limit the position of the bottle cap 2, but also allow the connecting band 6 to coil around after the bottle cap 2 separates from the bottle mouth 9. The bottle cap 2 and the connecting band 6 can be limited to the outside of the bottle body 1 by the elastic sheet 5 to prevent the bottle cap 2 from detaching. At the same time, when the bottle cap 2 and the bottle mouth 9 are screwed together, the shape of the connecting band 6 can be changed to distinguish multiple sets of bottles.
[0028] Specifically, such as Figure 2 and Figure 4 As shown, the anti-slip component includes anti-slip textures on the outer wall of the bottle body 1. The bottle body 1 has a recessed section 3 in the middle. The inner wall of the recessed section 3 is integrally formed with two sets of inner grooves 4, which are symmetrically distributed on both sides of the longitudinal end of the recessed section 3. When holding the bottle body 1, the operator's hand will combine with the anti-slip textures on the outer side of the bottle body 1, and the operator's fingers can also combine with the two sets of inner grooves 4. The gradient setting of the inner grooves 4 and the bottle body 1, combined with the anti-slip textures on the outer side of the bottle body 1, can effectively improve the anti-slip effect of the plastic bottle, thereby improving the stability of the plastic bottle in use.
[0029] Specifically, such as Figure 2 and Figure 3As shown, the constraint assembly includes a limiting ring 10 and a limiting ring 14. Both limiting rings 10 and 14 are fixedly installed on the outer wall of the bottle cap 2, and are distributed on both sides of the vertical end of the support ring 7. The vertical position of the support ring 7 is limited by the limiting rings 10 and 14. The limiting ring 14 can also cooperate with the sealing gasket 13. The connecting assembly includes an insert ring 12 and a sealing gasket 13. Both the insert ring 12 and the sealing gasket 13 are fixedly installed at the bottom of the support ring 7. An elastic sealing ring 17 and an elastic sealing ring 18 are fixedly installed on the inner wall of the outer ring 15. Ring 12 is inserted between elastic sealing ring 17 and elastic sealing ring 18. The support ring 7 is pushed by the protruding edge 11. The support ring 7 drives the insertion ring 12 to move downward until the sealing gasket 13 at the bottom of the support ring 7 abuts against the top of the limiting ring 14. At this time, the insertion ring 12 is inserted between elastic sealing ring 17 and elastic sealing ring 18. The elastic sealing ring 17 and elastic sealing ring 18 are tightly fitted with the insertion ring 12, thus ensuring the stability of the position of the insertion ring 12. This allows the support ring 7, the insertion ring 12 and the outer ring 15 to form a closed chamber on the outside of the bottle mouth 9 and the bottle cap 2, thereby achieving the resealing of the bottle.
[0030] Specifically, such as Figure 1 and Figure 2 As shown, the limiting component includes a connecting band 6, with both ends of the connecting band 6 fixedly connected to the bottle cap 2 and the outer wall of the bottle body 1, respectively. The outer wall of the bottle body 1 is provided with an elastic part for pressing down the connecting band 6. The elastic part includes an elastic sheet 5, which is fixedly installed on the outer wall of the bottle body 1 and pressed against the outside of the connecting band 6. The elastic sheet 5 itself can elastically stretch and contract, preferably a TPU elastic band. A connecting block 19 is fixedly installed at the open end of the connecting band 6. A fixing seat 8 is integrally formed on the outer wall of the bottle body 1. The connecting block 19 is fixedly connected to the fixing seat 8 by adhesive. The connecting band 6 can not only limit the position of the bottle cap 2, but also allow the connecting band 6 to coil around after the bottle cap 2 is separated from the bottle mouth 9. The bottle cap 2 and the connecting band 6 can be limited to the outside of the bottle body 1 by the elastic sheet 5 to prevent the bottle cap 2 from detaching. At the same time, multiple sets of bottles can be distinguished by changing the shape of the connecting band 6 when the bottle cap 2 and the bottle mouth 9 are screwed together.
[0031] Working principle: Rotating the bottle cap 2 to screw it onto the bottle mouth 9 achieves initial sealing of the bottle. During this process, the support ring 7 is pulled by the connecting band 6, and the elastic sheet 5 is pressed against the outside of the connecting band 6, thus providing axial constraint for the support ring 7. This prevents the rotation of the bottle cap 2 from having a significant impact on the support ring 7. Then, the support ring 7 is pushed by the protruding edge 11, and the support ring 7 drives the insert ring 12 to move downward until the sealing gasket 13 at the bottom of the support ring 7 abuts against the top of the second limiting ring 14. At this time, the insert ring 12 is inserted between the first elastic sealing ring 17 and the second elastic sealing ring 18. The first elastic sealing ring 17 and the second elastic sealing ring 18 are tightly fitted with the insert ring 12, thus ensuring the stability of the position of the insert ring 12. This allows the support ring 7, the insert ring 12, and the outer ring 15 to form a shape on the outside of the bottle mouth 9 and the bottle cap 2. The closed chamber achieves resealing of the bottle body, further improving the bottle's sealing performance. The connecting strap 6 not only limits the position of the cap 2, but also allows the connecting strap 6 to coil around the cap 2 after it separates from the bottle mouth 9. The cap 2 and the connecting strap 6 can be fixed to the outside of the bottle body 1 by the elastic sheet 5, preventing the cap 2 from detaching. At the same time, multiple sets of bottles can be distinguished by changing the shape of the connecting strap 6 when the cap 2 and the bottle mouth 9 are screwed together. When holding the bottle body 1, the operator's hand will combine with the anti-slip texture on the outside of the bottle body 1, and the operator's fingers can combine with the two sets of inner grooves 4. The gradient setting of the inner grooves 4 and the bottle body 1, combined with the anti-slip texture on the outside of the bottle body 1, can effectively improve the anti-slip effect of the plastic bottle, thereby improving the stability of the plastic bottle in use.
