Abstract
A hose for packaging a paste-like material relates to a medicinal package, in particular to a hose for packaging an ointment. The utility model comprises a hose body and a hose cover 3; and a hose head 1 and a hose wall 2 are subject to the secondary extrusion and injection for the formation of the hose body. The utility model is characterized in that the hose body is a compound structure alternated between polyethylene 5 and adhesive 6, and the hose cover 3 covers and closes the hose head 1. The utility model has the advantages of novel structure, simple process and utility.
Description
Technical field
This utility model relates to a kind of pharmaceutical pack, particularly a kind of packaging tube of ointment.
Background technology
Existing ointment flexible pipe mostly is plastics or the aluminium plastic composite material squeeze note forms.The monolayer plastic flexible pipe is used polyethylene always, and it is a kind of non-polar high polymer polymer, and chemicalses such as acid, alkali are all had good anti-corrosion capability; The resistance infiltration coefficient is lower and breathability is strong, and it is very easily lost that the ointment pot-life is subjected to the aromatics composition that bigger restriction, particularly ointment contain.Aluminium plastic composite material is because added aluminium foil, and the rebound performance of flexible pipe will be subjected to certain influence; Its socket processing technique generally adopts the high frequency reel, and elder generation extrudes tubulation after the base material hot melt adhesion is made compound dish material.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, and the paste packaging tube of a kind of MULTILAYER COMPOSITE and secondary extruding is provided.
Paste packaging tube described in the utility model is made of body and pipe lid, and body is that tube head and tube wall secondary extruding get, the composite construction that body is polyethylene, binding agent, polyethylene is alternate, and pipe covers and tube head covers.
Described body is a three-layer composite structure: polyethylene, binding agent, the three-layer composite structure that polyethylene is alternate.
Described body is five layers of composite construction: polyethylene, binding agent, ethenol copolymer, binding agent, five layers of composite construction that polyethylene is alternate.
Described pipe has covered evagination, and the size of evagination and the internal diameter of tube head are complementary.
Paste packaging tube described in the utility model has been used the EVOH material with better barrier property, and its barrier property is poly 10,000 times, overcomes the resistance of monolayer polyethylene plastic flexible pipe and oozes the low shortcoming of coefficient.Adopt the structure of MULTILAYER COMPOSITE simultaneously, internal layer adopts the polyethylene of acid and alkali-resistance to guarantee the steady quality of ointment in the shelf-life effectively.The socket processing technique is that five layer materials are extruded jointly, trombone slide is made, and more plastic-aluminum combined flexible pipe technology is simple.The flexible pipe manufacturing process adopts the secondary squeeze note, and tube head and body divide the secondary squeeze note, have satisfied commercial production, and particularly the coupling of covering evagination and tube head internal diameter is managed in the commercial production requirement during tube head different in size, has protected the quality stability of mastic effectively.This utility model novel structure, technology is simple, practicality.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model cross-sectional view.
Among the figure, the 1-tube head, the 2-tube wall, 3-manages lid, 4-evagination, 5-polyethylene, 6-binding agent, 7-ethenol copolymer.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing, but be not limited to embodiment.
The described paste packaging tube of present embodiment, covering 3 by body and pipe constitutes, body is that tube head 1 gets with tube wall 2 secondary extrudings, body is the alternate three-layer composite structure of polyethylene 5, binding agent 6, polyethylene 5, the pipe cover 3 and tube head 1 cover, pipe covers evagination 4 on 3, the internal diameter of the size of evagination 4 and tube head 1 is complementary.
Embodiment 2
Described paste packaging tube, body are five layers of composite construction: five layers of composite construction that polyethylene 5, binding agent 6, ethenol copolymer 7, binding agent 6, polyethylene 5 are alternate.All the other are with embodiment 1.
Claims (4)
1, a kind of paste packaging tube, be made of body and Guan Gai (3), body is that tube head (1) gets with tube wall (2) secondary extruding, it is characterized in that, body is polyethylene (5), binding agent (6), the alternate composite construction of polyethylene (5), and pipe lid (3) covers with tube head (1).
2, paste packaging tube according to claim 1 is characterized in that, described body is a three-layer composite structure: polyethylene (5), binding agent (6), the alternate three-layer composite structure of polyethylene (5).
