CN2201350Y - Bottle sealing plug - Google Patents

Abstract

Disclosed is a bottle opening sealing plug which belongs to a bottle opening sealing device. The utility model is composed of a valve core, an annular sealing ring, a backing ring, a cover, and a startstop wrench, wherein, the valve core forms a column shape, the end of the valve core is provided with an annular crossette, and the top of the valve core is provided with a pin hole; the sealing ring and the backing ring are alternately strung on a valve post, and the cover is strung; finally, the valve core and the wrench head of the wrench are in shaft connection through a male pin. Because the wrench head forms a fan shape, the curvilinear equation of a fan-shaped arc is an increasing function. When the wrench head is rotated, the wrench head can compress or loosen the sealing ring for achieving a startstop purpose. The utility model has the advantages of good sealing performance and repeated use.

Description

Bottle sealing plug

The utility model relates to sealing arrangement, relates in particular to " O " type sealing arrangement.

As everyone knows, the various bottled drinks of kind kind such as at present commercially available most drinks, mineral water, Coca-Cola, the hat type gland that has packing seal is adopted in its bottleneck sealing mostly, perhaps adopts the screw-type cap, and minority adopts cylindrical cork.These bottle caps or bottle stopper, once unpacking, bottle cap just can not be again with or during at repeated usage, can not keep good sealing.So it is fresh-keeping that the interior residue of bottle beverage just is difficult to continue, and perhaps keeps its original taste.

The utility model aim to provide a kind of can repeated use and still can keep the bottle stopper of excellent sealing performance.

The utility model is to realize above-mentioned purpose like this:

Bottleneck seal cover cap (referring to accompanying drawing) covers (4) and a keying spanner (5) formation by a spool (1), a 1-3 grommet type seals (2), a 1-2 gasket ring (3), a hat type lid or round formula.Described spool (1) is cylindrical, and there is a diameter its underpart than the big 2-10 millimeter of body diameter, but is slightly smaller than the annular arrangement crossette (6) of bottleneck internal diameter, and its top is columniform or its proximal portion of rectangular column has a pin-and-hole; Described grommet type seals (2) is made with elastomeric material, its external diameter is slightly smaller than the bottleneck internal diameter, and its internal diameter is equal to or slightly greater than the external diameter of spool (1), described gasket ring (3), its external diameter is slightly smaller than its internal diameter of bottleneck internal diameter and then is a bit larger tham footpath outside the spool (1), and gasket ring becomes bearing fit with spool.Described lid (4) is hat type or circular plate type, and its external diameter is not less than the bottleneck external diameter, and its center has a diameter to be a bit larger tham the circular hole or the rectangular opening of spool column diameter, and its effect is as fulcrum and stops following junk.Described keying spanner (5), form with handgrip (8) two parts by the affixed mutually head (7) of removing, the front elevation of removing head (7) is fan-shaped, its top end has a pin-and-hole, ogive equation γ (101) is an increasing function, stressed even when opening and closing for maintenance, get: γ (| θ |)=a+b| θ |; Wherein a removes the minimum spoke radial line of hole, the crown to fan-shaped arc, and represents that its length, the length of b are 1/2 a～1/8 a, and θ is that apical pore is to the spoke footpath γ (θ) of fan-shaped arc and the angle of a.Handgrip (8) with remove the head (7) Joint, the angle of handgrip and a is advisable with 45 °～135 °.

Assembling and use:

Grommet type seals (2) and gasket ring (3) are respectively gone here and there on spool (1) cylinder, then lid (4) is gone here and there on spool (1) post, will open and close spanner (5) at last and connect with pin (9) by the hole on it, the formation normal-running fit with spool (1).

During use, depress or carry on handgrip (8), remove head and rotate, the identity distance that makes its ogive and lid (4) will push away on the spool (1) then from shortening, contact, and the compression grommet type seals makes seal ring tightly contact with the bottle inwall along lateral expansion, and formation seals; During the breakdown bottle stopper, with handgrip (8) backward rotation, make line a be in the vertical state, grommet type seals is restored under self elasticity, just can take off bottle stopper easily.

Description of drawings:

Accompanying drawing one bottleneck plug construction scheme drawing, wherein

The 1-spool, the 2-grommet type seals, the 3-gasket ring, the 4-lid, 5-spanner, the crossette on the 6-spool, the 7-spanner remove head, 8-spanner handgrip, a-are removed head last 0 to the shortest spoke radial line of fan-shaped arc, and θ-remove any spoke radial line γ (θ) and line a are the gap between angle, h-line a remove when the vertical attitude and cover.

Embodiment and effect:

I have made several sealing bottle corks by above-mentioned design plan, easy to use, repeated use still can keep excellent sealing performance, make to sum up except that the b value 1/2 a～1/8 α, preferably get (π)/4 b-h and equal 1/10～1/4 grommet type seals gross thickness, a fan-shaped in addition two ends of removing, respectively have one with curve tangentially become approximately 20-30 ° chamfering plane can be in the sealing attitude to remove a holding position stable.

Claims (2)

1, a kind of bottleneck sealing plug is characterized in that: it is made of spool (1), a 1-3 grommet type seals, a 1-2 gasket ring (3), 1 lid (4) and a keying spanner (5); Described spool becomes cylindrical, and there is a diameter its underpart than the big 2-10 millimeter of body diameter, but its top of annular arrangement crossette (6) that is slightly smaller than the bottleneck internal diameter is columniform or the square cylindricality, and its proximal portion has a pin-and-hole; Described grommet type seals (2) is made with elastomeric material, and its external diameter is slightly smaller than the bottleneck internal diameter and internal diameter is equal to or slightly greater than the spool external diameter; Described gasket ring (3), its external diameter is slightly smaller than the bottleneck external diameter, and its internal diameter is a bit larger tham the spool external diameter, gasket ring becomes bearing fit with spool; Described lid (4) is hat type or circular plate type, and its external diameter is not less than footpath outside the bottleneck, and its center has circular hole or the rectangular opening that diameter is a bit larger tham spool; Described spanner (5) is made up of with handgrip (8) the affixed mutually head (7) of removing, the front elevation of removing head (7) becomes fan-shaped, its top end has a pin-and-hole, ogive γ (θ) is an increasing function, its assembling is as follows: grommet type seals (2) is respectively gone here and there on the spool post with gasket ring (3), then lid is gone here and there on the spool post, at last keying is removed head and be coupling with pin by the through hole on it with spool.

2, bottleneck seal cover cap according to claim 1, it is characterized in that: the described ogive equation γ (θ) that removes head, its best curve equation is γ (| θ |)=a+b| θ |, wherein a removes minimum spoke radial line and the line length of hole, the crown to fan-shaped arc, b length is 1/2 a～1/8 a, θ is that apical pore is to the spoke footpath γ (θ) of fan-shaped arc and the angle of a, and satisfy (π)/4 b-h and equal 1/10～1/4 grommet type seals gross thickness, wherein h is that line a removes the gap between head and the lid when the vertical state.
