Description

Technical Field

[0001] The present invention relates to the field of packaging bottles, in particular to a center-outlet elastic sheet opening and closing cover extrusion bottle. Background Art

[0002] When used at home or during hotel stays on business trips, shower gels, shampoos, etc. are usually provided in the bathroom. Whether it is an inverted bottle or an upright bottle, it is common for hotel customers to accidentally knock it over or cause the bottle to tip over, resulting in the internal liquid flowing out, which may affect environmental hygiene and waste resources. Summary of the Invention

[0003] In order to solve the technical problem of the internal liquid flowing out caused by the tipping of the bottle body, the present invention provides a center-outlet elastic sheet opening and closing cover extrusion bottle.

[0004] The technical solution of the present invention is as follows: The center-outlet elastic sheet opening and closing cover extrusion bottle includes a bottle cap, an inner bottle cap and a bottle body. The upper part of the bottle body is provided with a bottle mouth, and the bottle mouth is installed with the inner bottle cap through a thread. The bottle cap and the inner bottle cap are in snap-fit. The inner wall of the bottle cap includes a first wall body and a second wall body. The outer wall of the inner bottle cap is provided with a card slot. A snap button is arranged in the second wall body and is located in the card slot on the outer wall of the inner bottle cap. The card slot is a curved slot. A through hole a is arranged in the center of the bottle cap. A convex ring is formed by the bottom of the inner wall of the through hole a protruding downward. A sealing ring is arranged between the convex ring and the first wall body. A silica gel cover is arranged on the inner wall of the sealing ring. The silica gel cover is provided with a cross knife line opening. The middle of the silica gel cover protrudes downward into a bowl shape. The silica gel cover is located below the through hole a. A bayonet seat is arranged in the middle of the inner bottle cap. A connecting body is arranged between the bayonet seat and the inner wall of the inner bottle cap, and a gap is left between the connecting bodies. The sealing ring is movably clamped or disengaged from the bayonet seat through the bottle cap.

[0005] The inner bottle cap is provided with a threaded cap housing that wraps the bottle mouth. The outer side wall of the threaded cap housing is fixedly connected to the bottle mouth through a thread, and the inner side wall contacts the inner wall of the bottle mouth downward.

[0006] The surface of the bottle cap is smooth. The bottle cap and the inner bottle cap are in snap-fit. A convex block is arranged on the second wall body of the bottle cap.

[0007] The bottom of the bottle body is in an inclined shape, and a hanging hole is arranged horizontally on the inclined surface.

[0008] The sealing ring includes an outer retaining ring and an inner clamping ring. The inner wall of the outer retaining ring and the inner clamping ring are connected by an annular ring. The top of the inner clamping ring is lower than the outer retaining ring, and the bottom of the inner clamping ring extends beyond the outer retaining ring. A retaining ring is arranged on the upper part of the inner clamping ring. A ring of clamping rings is arranged on the outer side of the silica gel cover. The clamping ring is clamped between the outer retaining ring and the retaining ring. The upper part of the clamping ring contacts the convex ring, and the lower part contacts the annular ring. A clamping body for clamping the outer retaining ring is arranged on the inner wall of the first wall body.

[0009] The bottom of the bottle body is flat.

[0010] Using the technical solution of the present invention, the structure is novel, the design is ingenious and simple. When the fixing assembly interacts with the inner cap of the bottle cap, it is a vertically movable structure. When not in use, the lower inner wall of the snap ring in the sealing ring catches the bayonet seat to prevent the liquid inside from flowing out due to the tipping of the bottle body. When in use, the lower inner wall of the snap ring in the sealing ring disengages from the bayonet seat. In the middle of the silicone cap is a cross ligament knife edge of a silicone soft elastic sheet. The knife edge opens to discharge liquid under the action of pressure and can be used as a snap-open type cap. It can be closed without being pressed back to its original shape. When the inner cap of the bottle cap is tightened, it always maintains a stable closed state. When in use, just open the bottle cap. The key is that when the bottle cap is in the open state, it does not squeeze and does not leak liquid or water, and does not leak even when it is tilted sideways, which is clean, hygienic, environmentally friendly and tidy.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be further described below in conjunction with the drawings and embodiments. Embodiment 1

[0013] As Figure 1 、 2, the center liquid outlet elastic sheet opening and closing type cover extrusion bottle shown in 3, 4, 5, 6, 7, 8, 9, 10, includes a bottle cap 1, an inner bottle cap 2 and a bottle body 3. The upper part of the bottle body 3 is provided with a bottle mouth, and the bottle mouth is installed with the inner bottle cap 2 through threads. The bottle cap 1 and the inner bottle cap 2 are in snap fit. The inner wall of the bottle cap 1 includes a first wall body and a second wall body. The outer wall of the inner bottle cap 2 is provided with a card slot 9. A snap button 5 is arranged inside the second wall body, and the snap button 5 is in the card slot 9 on the outer wall of the inner bottle cap 2. The card slot 9 is a curved slot. A through hole a6 is arranged in the center of the bottle cap 1. A convex ring 4 protrudes downward from the bottom of the inner wall of the through hole a6. A sealing ring 7 is arranged between the convex ring 4 and the first wall body. A silica gel cover 8 is arranged on the inner wall of the sealing ring 7. The three components of the bottle cap 1, the sealing ring 7 and the silica gel cover 8 form a fixed assembly. The silica gel cover 8 is provided with a cross knife line opening. The middle of the silica gel cover 8 protrudes downward into a bowl shape. The silica gel cover 8 is located below the through hole a6. A bayonet seat 14 is arranged in the middle of the inner bottle cap 2. A connecting body 15 is arranged between the bayonet seat 14 and the inner wall of the inner bottle cap 2, and there is a gap between the connecting bodies 15. The sealing ring 7 is movably clamped or disengaged from the bayonet seat 14 through the bottle cap 1. The cover opening of the inner bottle cap 2 is clamped between the first wall body and the second wall body, and there is a bayonet seat 14 in the middle of the cover opening of the inner bottle cap 2.

[0014] The inner bottle cap 2 is provided with a threaded cap shell that wraps the bottle mouth. The outer side wall of the threaded cap shell is fixedly connected to the bottle mouth through threads, and the inner side wall contacts the inner wall of the bottle mouth downward.

[0015] The surface of the bottle cap 1 is smooth, or matte, etc. The bottle cap 1 and the inner bottle cap 2 are in snap fit. A convex block 10 is arranged on the second wall body of the bottle cap 1.

[0016] The bottom of the bottle body 3 is in an inclined shape, and a suspension hole is arranged horizontally on the inclined surface. There are also bottle shapes such as upright circles.

[0017] The sealing ring 7 includes an outer retaining ring 12 and an inner retaining ring 11. The inner wall of the outer retaining ring 12 and the inner retaining ring 11 are connected through an annular ring. The top of the inner retaining ring 11 is lower than the outer retaining ring 12, and the bottom of the inner retaining ring 11 extends beyond the outer retaining ring 12. A retaining ring is arranged on the upper part of the inner retaining ring 11. A ring of clamping rings 13 is arranged on the outer side of the silica gel cover 8. The clamping rings 13 are clamped between the outer retaining ring 12 and the retaining ring. The upper part of the clamping rings 13 contacts the convex ring 4, and the lower part contacts the annular ring. A buckling body 16 for buckling the outer retaining ring 12 is arranged on the inner wall of the first wall body. The outer retaining ring 12 and the inner retaining ring 11 are in an inverted Z shape, and the retaining ring blocks the clamping rings 13.
