Description

Technical field

[0001] The present utility model relates to the technical field of hoses, more specifically a TPE soft-head hose. State of the art

[0002] Tubular packaging is widely used in cosmetics, pharmaceuticals, and similar fields due to its advantages of portability and leak-proof design. Conventional tubular packaging is often molded in one piece from polyethylene (PE), with a nozzle typically made of a rigid PE structure. This material has obvious drawbacks: (1) poor tactile experience: the rigid nozzle is hard and icy cold upon contact with the skin, particularly for products like face creams and lotions intended for direct application; (2) difficult joining of heterogeneous materials: while a soft thermoplastic elastomer (TPE) is used for the nozzle to improve the tactile experience, conventional injection molding processes, due to the molecular structure and melting point difference between TPE and PE, can easily lead to layering or separation at the interface.

[0003] Therefore, it is urgently necessary to develop a hose structure that offers both a skin-friendly feel and a high barrier capacity, and is reliably molded in one piece from heterogeneous materials and suitable for efficient production. Disclosure of the utility model

[0004] With regard to the shortcomings of the existing technology, the present utility model provides a TPE soft-head hose. In the TPE soft-head hose, the contact feel is improved by using a TPE injection head, and a five-layer co-extrusion process optimizes barrier capability and production yield. At the same time, the problem of bond strength at an interface of the heterogeneous TPE / PE material is solved by segmented injection molding in combination with the structure of the hose body.

[0005] To achieve the above objective, the present utility model provides the following technical solution: A TPE soft-head hose comprising a hose body and a nozzle, wherein the hose body comprises, from the outside in, an outer layer, a first adhesive layer, a barrier layer, a second adhesive layer and an inner layer, and the nozzle is made of a TPE material.

[0006] Furthermore, a suspension platform and a resting point are provided on a head part of the hose body; the spray head is formed integrally with the hose body at the location of the suspension platform and the resting point.

[0007] Furthermore, the barrier layer material is ethene-vinyl alcohol copolymer.

[0008] Furthermore, the material of the outer layer and the inner layer is polyethylene.

[0009] Furthermore, the material of the first adhesive layer and the second adhesive layer is maleic anhydride-modified polyolefins.

[0010] Furthermore, the shape of the spray head can be a circle, an oval, a square, a rectangle, a triangle, or an extraneous shape.

[0011] In comparison with the existing technology, the advantageous effect of the present utility model consists of the following: 1. To significantly enhance the user experience

[0012] The nozzle uses a soft TPE material instead of the conventional hard PE; the contact feel is soft and skin-friendly, making it particularly suitable for scenes involving direct skin contact, such as cosmetics. 2. To strengthen the reliability of the structure

[0013] The suspension platform and locking point are provided at the head of the hose body, which increases the contact area of ​​the TPE nozzle with the PE hose body, thus increasing the bond strength of the heterogeneous materials and avoiding the risk of separation. 3. High barrier capability and production efficiency must be taken into account.

[0014] Structure of a five-layer co-extrusion tube body (outer layer / adhesive layer / barrier layer / adhesive layer / inner layer): the barrier layer effectively isolates oxygen, protecting the inner object; the adhesive layer (maleic anhydride-modified polyolefins) ensures the bonding strength between layers; the optimization of a layered extrusion process increases production yield and production capacity. 4. Strong universality of the method

[0015] Several nozzle shapes (circular, oval, square, foreign shape, etc.) are supported to meet the packaging needs of premium cosmetics. Explanation of the illustrations
