Description

Technical Field

[0001] This utility model relates to the field of packaging, and in particular to a plastic beverage bottle preform with a stepped wall thickness. Background Technology

[0002] As market competition intensifies, consumers' demand for product personalization continues to grow. By using a design with stepped changes in wall thickness, personalized features such as gradient color effects on the preform can be achieved, meeting the market's diverse needs for product appearance.

[0003] However, some existing plastic beverage bottle preforms with stepped wall thicknesses are typically designed to meet consumer demand by simply changing the preform's wall thickness, without considering the inconvenience this change in wall thickness can cause to the consumer's hand.

[0004] Therefore, a plastic beverage bottle preform with a stepped wall thickness is proposed to address the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a plastic beverage bottle preform with a stepped wall thickness, aiming to improve the problem of inconvenience in holding the bottle in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A plastic beverage bottle preform with a stepped wall thickness includes a preform body, characterized in that: the preform body is fixedly connected to a limiting ring, the preform body has a plurality of slots II, the slots II are located below the limiting ring, the preform body is provided with a limiting ring, the limiting ring is used in conjunction with the slots II, and the preform body has a slot I, the slot I is located below one of the slots II. As a further description of the above technical solution: The slots are configured as rectangular frame slots that are symmetrically distributed in the preform. As a further description of the above technical solution: The second slot is configured as an inclined annular limiting slot distributed vertically on the blank body; As a further description of the above technical solution: The limiting ring is located in the middle of the two slots and is an oblique limiting ring with the same inclination angle as the two slots. As a further description of the above technical solution: The thickness of the inner wall of the embryonic body increases in a stepwise manner with height; As a further description of the above technical solution: The limiting ring has a three-slotted hole, which is an oblique slot.

[0007] This utility model has the following beneficial effects: In this invention, the thickness of the inner wall of the blank is changed to meet different consumer needs. The product ingredient list can be placed in the slot one opened on the blank. The two slot two are processed to form oblique slots, which facilitates stability when the consumer holds the blank. Specifically, when the fingers are placed in the corresponding slots, the friction between the fingers and the slots, as well as the friction between the gaps between the fingers and the limiting ring, achieves a strong grip on the blank and prevents it from falling off during use.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Reference Figures 1 to 3This utility model provides an embodiment of a plastic beverage bottle preform with a stepped wall thickness, comprising a preform body 1, which is based on existing mature technology. The wall thickness of the inner wall of the preform body 1 increases in a stepped manner with height. A limiting ring 5 is fixedly connected to the preform body 1 to limit the rotation distance of the bottle cap on the preform body 1. The limiting ring 5 has a slot 6, which is used to fix the bottle cap to the preform body 1 by engaging with a protrusion on the bottle cap to form a secondary fixation. The slot 6 is an oblique slot. The preform body 1 has several slots 4 for placing fingers. A limiting ring 3 is provided between two slots 4. To aid in fixation, slot 2 4 is set as an inclined circular limiting slot with vertical distribution on the blank body 1. Slot 2 4 is located below the limiting ring 5. The blank body 1 is provided with a limiting ring 3 and a finger limiting ring 3. When two fingers are placed in slot 2 4, the limiting ring 3 is located in the middle of the two slots 2 4 and is an inclined limiting ring with the same inclination angle as the two slots 2 4. The limiting ring 3 is used in conjunction with slot 2 4. Slot 1 2 is opened on the blank body 1. Slot 1 2 can be used to place the product composition table. Slot 1 2 is located below one of the slots 2 4. Slot 1 2 is set as a rectangular frame slot with symmetrical distribution on the blank body 1.

[0012] Working principle: After the blow molding process is completed, according to the size of the slot 2 opened on the blow-molded preform 1, a product composition table of appropriate size is selected and fixed to the slot 2 by means of adhesive or other methods. After blow molding, the slot 4 is easy for the user to hold during use. When the user's fingers are placed along the slot direction of the slot 4, the clamping force on the preform 1 is increased. In addition, the limiting ring 3 separates the two slots 4 and conforms to the human hand holding habit, forming two fingers clamping the limiting ring 3, further increasing the stability of holding the preform 1.

[0013] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
