Description

Bottle cap with tight fitting ring

Technical Field

The utility model relates to a bottleneck packaging technology field especially relates to a bottle lid with tight fit ring.

Background

Wine products, while their cost can be tolerated, are often designed with a mouth on the lid. Among many bottle mouth designs, there is a design of a non-return bottle mouth assembly, when opening, a pull rod in the bottle mouth assembly is pulled up by hand, and the pulled-up pull rod cannot return, so as to give a prompt to a user that a bottle is opened later. However, this technique has certain limitations. When the non-return bottle mouth assembly is applied to a combined bottle cap, particularly under the condition that the overall height of the combined bottle cap is small, the handle height of the pull rod is correspondingly made small, and the pull rod with the small size is inconvenient for a user to pinch and pull upwards.

SUMMERY OF THE UTILITY MODEL

In order to solve the limitation existing in the above design, the utility model provides a bottle cap with tight fit circle to when the solution applies the stopping bottleneck subassembly to the combination bottle lid, open the inconvenience that the in-process brought at the bottle lid.

The utility model discloses a concrete technical scheme as follows:

the bottle cap with the tight fit ring comprises an upper cover, wherein the tight fit ring capable of being tightly fitted in an interference fit mode is arranged at the top of the inner side of the upper cover.

Furthermore, the part which is tightly matched with the tight fit ring in an interference fit mode is a pull rod of the non-return bottle mouth component.

Furthermore, the tight fit ring is a notch at the top of the inner side of the upper cover.

Furthermore, the tight fit ring is a circular ring extending downwards from the top of the inner side of the upper cover.

Furthermore, an upper cover thread corresponding to the bottle mouth thread is arranged on the inner side of the upper cover.

The utility model has the advantages that:

a bottle lid with tight fit circle, simple structure when unscrewing the upper cover, can upwards pull out the pull rod automatically, the inconvenience of bringing when having saved the hand power pull rod.

Detailed Description

The preferred structures and methods of practicing the invention are further described below in conjunction with the following figures and detailed description.

Example one

As shown in figures 1, 2, 3, 7.

A bottle cap with a tight fit ring comprises an upper cap 5; the top of the inner side of the upper cover 5 is provided with a tight fit ring 52 which can be tightly fitted through an interference fit manner.

The component tightly fitted with the tight fitting ring 52 in an interference manner may be a device arranged at the bottle mouth, such as a bottle stopper capable of rotating relative to the bottle mouth, or a pull rod of a non-return bottle mouth assembly.

The embodiment is described by taking the pull rod of the anti-retreat bottle mouth assembly as an example.

An upper cover thread 51 is arranged on the inner side of the upper cover 5, and a close-fitting ring 52 matched with the pull rod 2 is arranged at the top of the inner side of the upper cover; the tight fit ring 52 is a notch at the top of the inner side of the upper cover; combining the bottle cap with the tight fit ring and the backstop bottle mouth component into a combined bottle cap;

the non-return bottle neck component comprises a bottle neck 1, and bottle neck threads 14 are arranged on the outer side of the bottle neck 1; the bottle mouth connecting piece also comprises a connecting piece 3 which can connect the bottle mouth 1 with the bottle mouth;

the bottle mouth 1 and the connecting piece 3 are fixedly connected in an integral injection molding mode;

the bottle mouth 1 is provided with an inner cylinder 11, the inner cylinder 11 is a hollow cylinder coaxial with the bottle mouth 1, the side wall of the inner cylinder is provided with an inner cylinder liquid outlet 12, and a buckle 13 is arranged below the inner cylinder liquid outlet;

the inner side of the connecting piece 3 is provided with an inner buckle 31 and an inner anti-rotation rib 32;

the non-return bottle neck component also comprises a pull rod 2; the main body of the pull rod 2 is a hollow cylinder with the upper end closed and the lower end opened, the hollow cylinder is coaxial with the inner cylinder 11, the lower end opening is communicated with the bottle opening, the side wall of the pull rod 2 is provided with a pull rod liquid outlet 22, the lower part is connected with a limiting backstop member 21, and the shape of the limiting backstop member 21 includes but is not limited to an inverted horn mouth shape;

the upper cover 5 is matched with the bottle mouth thread 14 through an upper cover thread 51 and screwed on the outer side of the bottle mouth 1;

the pull rod 2 is upwards arranged in the inner cylinder 11 from the lower part of the inner cylinder 11; the pull rod 2 is in interference fit with the inner cylinder 11, and the pull rod liquid outlet 22 is positioned below the inner cylinder liquid outlet 12 and is not overlapped at all; the upper part of the pull rod 2 is arranged in the tight fitting ring 52 and is in interference fit with the tight fitting ring 52;

the bottle corresponding to the non-return bottle mouth component comprises a bottle neck 4, wherein a locking hoop 41 is arranged on the bottle neck 4;

when the combined bottle cap of the embodiment is used for sealing a bottle, the combined bottle cap is pressed on the bottle neck 4, so that the inner buckle 31 of the connecting piece 3 slides over the locking hoop 41 of the bottle neck 4 and is buckled below the inner buckle, the connecting piece 3 cannot be pulled upwards, the inner anti-rotation rib 32 is matched with the bottle neck anti-rotation rib 42, the connecting piece 3 cannot rotate relative to the bottle neck 4, and the sealing of the bottle is finished;

when the bottle is opened, the upper cover 5 is rotated, the tight fit ring 52 drives the pull rod 2 to rotate and rise by using friction force, so that the limiting backstop piece 21 slides over the buckle 13, the limiting backstop piece 21 is extruded by the buckle 13 and contracts inwards in the process of sliding over the buckle 13, the limiting backstop piece 21 is opened by using the elasticity of plastic after sliding over, and the pull rod 2 cannot return under the limitation of the buckle 13;

when the limiting backstop member 21 is positioned above the buckle 13, the upper cover 5 is separated from the pull rod 2, and then the pull rod 2 is rotationally adjusted to enable the pull rod liquid outlet 22 and the inner cylinder liquid outlet 12 to at least form partial overlap, so that liquid in the bottle can flow out through the pull rod liquid outlet 22 and the inner cylinder liquid outlet 12;

if the secondary sealing is needed, the pull rod 2 can be rotated, so that the pull rod liquid outlet 22 and the inner cylinder liquid outlet 12 are staggered left and right and are not overlapped completely, and the secondary sealing is completed in a closed state.

After the bottle is opened, the pull rod 2 is obviously higher than the initial position and cannot return the bottle, so that the bottle can be prompted to be opened again by a user, and the upper cover 5 cannot be screwed to the initial position even if the bottle mouth 1 can be screwed again due to the rising of the position of the pull rod 2, so that the user can recognize the bottle at a glance.

The connected mode of bottleneck 1 and connecting piece 3 except this embodiment integrative injection moulding, the components of a whole that can function independently is moulded plastics then and is even as an organic whole also the common fungible of this field is selected through modes such as welding, lock joint, because of it is right the utility model discloses the effect does not have the influence, and this place is not repeated.

Example two

As shown in fig. 4, 5, 6, 7.

The tight-fit ring 52 of the present invention, except the structure of the first embodiment, can be realized by extending a ring downwards from the top of the inner side of the upper cover 5, and the inner diameter of the ring is slightly smaller than the outer diameter of the upper part of the pull rod, so that the pull rod 2 is in interference fit with the ring;

other structures and combinations of the embodiments are the same as those of the first embodiment, and the description is not repeated.
