Description

Riveted bottle cap and packaging bottle comprising same

Technical Field

The utility model relates to a packing specifically is a riveting bottle lid and contain its packing bottle.

Background

The inventor discloses an easy-to-open bottle cap with publication No. CN212314362U, wherein an easy-to-open ring is connected to one end of an easy-to-open sheet close to the lower end edge of a side cover. The easy-to-draw ring is the working of plastics usually, and bottle lid body and the easy-to-draw piece of an organic whole with it are aluminium matter stamping workpiece usually, will link to each other the two in actual production, need shift to the injection molding machine after the punching press of bottle lid body is accomplished, thereby put into the mould with easy-to-draw piece and mould plastics within accomplishing the connection of the two, owing to there is the process of an intramode equipment, production efficiency is not high.

The other type of all-aluminum easy-to-draw bottle cap with the integrated easy-to-draw piece and pull ring has the defects of low efficiency and high manufacturing cost because the structure is more complex and can not be completed by one-time stamping.

In addition, the existing bottle cap is not provided with a mark for marking a bottle cap manufacturer generally, the mark can not stand out too much, the bottle cap is preferably invisible when not opened, the production can be facilitated, the production process is not increased, and the manufacturing cost is low.

SUMMERY OF THE UTILITY MODEL

In order to overcome one of the above-mentioned defects or defects of the prior art, the utility model provides a riveting bottle cap, the technical scheme who takes is:

a riveted joint bottle cap comprising a bottle cap body including a skirt extending downward to form a tear tab, different from the prior art: the bottle cap body and the plastic pull ring are riveted together through the riveting columns and the riveting holes.

Furthermore, the riveting column penetrates through the riveting hole to be pressed and thermally deformed to form a riveting head, and the overall dimension of the riveting head is larger than the diameter of the riveting hole.

Further, the end face of the rivet head is provided with a concave or convex marked by characters, numbers, letters or patterns.

The utility model provides a packing bottle that contains this kind of riveting bottle lid.

Compared with the prior art, the utility model discloses a special cooperation of dividing work of fortune's mode is with complicated product simplification for bottle lid body and plastics pull ring can both improve production efficiency greatly, reduction in production cost. And the pull ring also plays the role of advertisement or identification on the basis of not increasing the cost.

Detailed Description

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

Embodiment 1, the aluminum bottle cap body 1 shown in fig. 1 can be rapidly mass-produced by a punching machine, the bottle cap body 1 includes a skirt 11, the skirt 11 extends downward to form a tear tab 12, 3 riveting holes 13 are punched on the tear tab 12, and of course, 2 tear marks are punched on the outer surface of the bottle cap body 1 from the junction of the tear tab 12 and the skirt 11, connecting the cap top, and ending at the junction of the tear tab 12 and the skirt 11 and the middle part of the skirt opposite side, which is a conventional technology in the art and is not described herein again.

The plastic pull ring 2 shown in figure 2 is rapidly produced in large scale through an injection molding machine without in-mold assembly, and the inner side of the plastic pull ring 2 is provided with 3 riveting columns 21 with positions corresponding to the positions of the riveting holes 13.

During riveting, the rivet column 21 is passed through the riveting hole 13, as shown in fig. 3, the part of the rivet column 21 passed through the riveting hole 13 is subjected to pressure heat deformation by using heat sealing equipment or manual heat sealing pressure pliers, and the deformed rivet column 21 is formed into a rivet head 21 'as shown in fig. 4, wherein the overall dimension of the rivet head 21' is inevitably larger than the diameter of the riveting hole 13. Thus, the bottle cap body 1 and the plastic ring pull 2 are riveted together. In the embodiment, a mode of Futailor division cooperation is adopted to simplify complex products, so that the production efficiency of the bottle cap body and the plastic pull ring can be greatly improved, and the production cost is reduced.

In example 2, on the basis of example 1, the heat sealing equipment or the manual heat sealing pressure clamp of this embodiment has protrusions or recesses with letters, numbers, letters or patterns, and the recesses 22 or protrusions with letters, numbers, letters or patterns are formed on the end surface of the rivet 21' during heat sealing. Therefore, the pull ring also plays the role of advertisement or identification on the basis of not increasing the cost.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the invention is not limited to the embodiments described herein, but is capable of other embodiments with obvious modifications, variations, and equivalents without departing from the scope of the invention. Therefore, any simple modification, equivalent replacement, equivalent change and modification made to the above embodiments by the technical entity of the present invention all still belong to the protection scope of the technical solution of the present invention.
