Description

Bottle mouth screw cap structure with spring inner cap

Technical Field

The utility model relates to a take bottleneck spiral cover structure of spring inner cup relates to packing bottle lid structure, especially packing bottle spiral cover structure.

Background

The screw cap structure of the packaging bottle in the prior art is generally a single-layer tinplate bottle cap, the end edge of the single-layer tinplate bottle cap is inward curled and sealed to form a cap claw, and the cap claw is matched with a thread on the bottle neck of the packaging bottle to seal the bottle mouth to form the screw cap. The bottle cap structure mainly realizes the tightness of the sealing cap by means of the snap-in force of the cap claw and the threads, the snap-in force can be increased by screwing tightly, the sealing performance of the bottle cap and a bottle opening is stronger, and conversely, the sealing performance of the bottle cap and the bottle opening is weaker. The bottle cap with the structure is easy to deform after being used for a long time, and the sealing performance of the bottle cap is very poor. Therefore, the screw cap structure is suitable for the situation of one-time or several-time non-frequent opening.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a take bottleneck spiral cover structure of spring inner cup, this spiral cover structure non-deformable contains the inner cup and seals tightly, and the bottle lid can not become flexible naturally, and suitable splendid attire will be preserved for a long time and often open the use and store up the thing.

The utility model discloses technical scheme: a bottle mouth screw cap structure with a spring inner cap comprises a bottle neck with multi-head threads; the bottle cap with the cap claw is characterized in that the bottle cap with the cap claw is a double-layer tinplate bottle cap consisting of a bottle cap inner layer and a bottle cap outer layer, and more than three cap claws are arranged on the bottle cap inner layer; a flange is arranged on the cover claw on the inner layer of the bottle cover, an inner cover is arranged on the flange, the diameter of the inner cover is smaller than the inner diameter of the bottle cover, the inner cover can move up and down in a bottle cover inner cavity enclosed by the inner layer of the bottle cover, and a compression spring is arranged between the inner cover and the bottle cover; the flange is arranged for a circle along the circumference of the inner layer of the bottle cap for 360 degrees.

The screw thread of the bottle neck with the multi-head screw thread is a flat screw thread, and a downward convex pattern is arranged at the right end of each screw thread in an extending manner.

According to the bottle mouth screw cap structure with the spring inner cap, the bottom end of the outer layer of the bottle cap is inwards curled, sealed and pressed on the inner layer of the bottle cap, so that the outer layer of the bottle cap and the inner layer of the bottle cap are fixed together.

The utility model relates to a take bottleneck spiral cover structure of spring inner cup adopts the inside inner cup that can reciprocate that is equipped with of bottle lid, is equipped with the spring between inner cup and bottle lid inlayer, and makes the inner cup can tight closing cap bottleneck, and need push down the bottle lid earlier when opening the bottle lid and rotate again, so step can avoid the bottle lid of mistakenly opening by the young person. And the structure that the outer layer of the bottle cap and the inner layer of the bottle cap are fixed together plays a role in enhancing and tonifying the structure of the bottle cap. The utility model discloses both can realize traditional safety cap function, can strengthen the tonic effect again to the bottle lid structure, and sturdy structure, long service life contains the inner cup again simultaneously and seals tightly, and the bottle lid can not become flexible naturally.

Detailed Description

The present invention will be described in further detail with reference to the following examples and accompanying drawings.

Referring to fig. 1, fig. 2, fig. 3 and fig. 4, an embodiment of a bottle opening screw cap structure with a spring inner cap according to the present invention is shown. The bottle neck 2 comprises a bottle body 1 and a bottle neck 2 with a multi-thread 21, wherein the multi-thread 21 of the bottle neck 2 is a flat thread, namely the multi-thread 21 is parallel to a top edge 22 of the bottle neck. In this embodiment, the number of the multiple thread roots is four, and each of the multiple thread roots is formed by extending downward from the neck finish 22. At the right end of each thread a downward rib 211 extends. The utility model relates to a bottle mouth screw cap structure with spring inner cap, which also comprises a bottle cap 3 with cap claws 321, wherein the bottle cap 3 with cap claws 321 is a double-layer tinplate bottle cap composed of a bottle cap inner layer 32 and a bottle cap outer layer 31, and the bottle cap inner layer 32 is provided with four cap claws 321; a flange 322 is further arranged on the cover claw 321 of the inner layer 32 of the bottle cover, an inner cover 33 is arranged on the flange 322, the diameter of the inner cover 33 is smaller than the inner diameter of the bottle cover 3, the inner cover 33 can move up and down in a bottle cover inner cavity 35 defined by the inner layer 32 of the bottle cover, and a compression spring 34 is arranged between the inner cover 3 and the bottle cover; the flange 322 is provided with a circle along 360 degrees of the circumference of the inner layer 32 of the bottle cap, but the flange 322 may be provided intermittently along the circumference of the inner layer 32 of the bottle cap and need not be provided with a circle, as long as the purpose of blocking the inner cap 33 can be achieved. Therefore, the inner cover capable of moving up and down is arranged in the bottle cap, the spring is arranged between the inner cover and the inner layer of the bottle cap, so that the inner cover can tightly seal the bottle neck, the bottle cap is required to be pressed down and then rotated when the bottle cap is opened, and the step can prevent the bottle cap from being opened by minors by mistake. The utility model relates to a take bottleneck spiral cover structure of spring inner cup be in the outer 31 bottom of bottle lid is along 311 inward rolling up the seal and withhold the outer 31 of bottle lid and bottle lid inlayer 32 bottom reason 323 makes outer 31 of bottle lid and bottle lid inlayer 32 fixed together, and like this structure, the outer and bottle lid inlayer of bottle lid is fixed together has played the reinforcing and benefiting effect of bottle lid structure.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the inventive concept, and all of them belong to the protection scope of the present invention.
