Description

Technical Field

[0001] The utility model relates to composite packaging materials, semi-finished products, finished products and processing equipment for sealing open hole sections. Background Art

[0002] In the continuous research and development of its prior patent: Patent application number: CN202020146975.6, patent name: Liquid food composite paper container finished product assembly line, the applicant focused on opening (for installing bottle mouth, pressing film, etc.) and sealing or capping before filling. For example, patent application number: CN202020146968.6, patent name: A combined packaging unit and a container made thereof. Since the cap is added before filling, it is creatively discovered that the technical progress that needs to be further improved is that, due to the traditional solution: the bottle mouth or pressing film is directly welded to the opening through thermoplasticity, so there is a problem: the opening (whether square or round) surface is a force-bearing surface during production, transportation, and use. The section between the inner and outer ports needs to be wrapped and closed to ensure the quality of the contents filled in the container. On the contrary, the section of the outer end of the opening is subjected to the action of external air, water and external force, which will cause the composite material section of the opening end to be delaminated, resulting in the weakening or destruction of the structural strength of the container, and the quality or use cannot be guaranteed during production, transportation, storage and use.

[0003] In addition, especially for the sealing of square holes and other corners, there is stress concentration when the corners are sealed and welded, which makes the sealing effect poor and unsightly. Direct welding on the lower surface is used when setting the bottle cap, which easily leads to welding seal leakage, sometimes opening or delamination, resulting in pollution and waste.

DETAILED DESCRIPTION

[0052] like Figure 1-6 As shown, the composite packaging material, semi-finished product, finished product and processing equipment with sealed open hole sections in this embodiment, wherein the composite packaging material is not limited to composite materials such as paper-plastic or paper-aluminum-plastic and similar structures.

[0053] like Figure 1 As shown, the composite packaging material with an open cross-section seal of this embodiment includes an end face portion 1, which is a square in the figure, and can also be a hexagon, etc. The end face is preferably an integral surface; the end face portion 1 has an opening portion 18 for mounting a bottle cap, and if the opening portion is sealed by pressing a film, the structure is equivalent, and an edge portion 17 is arranged around the opening portion 18; a transition edge portion 13, i.e., a fold line, is arranged around the edge portion 17;

[0054] The opening 18 has a cut-away portion 23 so that a portion to be sealed is exposed. Figure 1 The structure in is preferred. As an extended protection, the end face portion 1 is entirely an opening portion 18 , and the edge portion 17 is not included in the protection range. In this case, the cross-sectional portion 23 overlaps with the transition edge portion 13 .

[0055] A cross-section wrapping layer 20 is sealed on the cross-section portion 23, thereby achieving cross-section sealing, which is also one of the innovative features of the present utility model.

[0056] The two ends of the end face portion 1 are connected with folding ears 19 through corresponding transition edges 13; they have folding lines as shown in the figure, but are not limited to the folding lines defined in the present invention. When there are folding ears, when they are folded, the cross-section portion 23 will be deformed, resulting in problems with the online automatic sealing of the opening, and it cannot be effectively sealed.

[0057] The side A2 and the side B3 are connected to the end face 1 through the corresponding transition edge 13; the most important thing is that the cross section 23 and the cross section wrapping layer 20 are melt-sealed or bonded, which can be drip-melted or prefabricated with a thin film edge. This is the main core.

[0058] For the convenience of actual processing and good manufacturability, an outer wrapping layer 22 is provided on the upper surface of the end face portion 1 and / or an inner wrapping layer 21 is provided on the lower surface; of course, it is better to have both surfaces, but the cost increase should also be considered.

[0059] The outer wrapping layer 22 and / or the inner wrapping layer 21 are connected to the cross-sectional wrapping layer 20, so as to achieve joint processing, thereby improving the stability of the cross-sectional wrapping layer 20 and preventing problems such as falling off, delamination or peeling;

[0060] A sealing member 24 may be provided at the opening 18. The sealing member, as the name implies, is a component for sealing the opening, generally a bottle cap, which may be injection molded or bonded;

[0061] The edge of the sealing member 24 is sealed with the outer wrapping layer 22, the cross-section wrapping layer 20 and / or the inner wrapping layer 21, and can be welded directly to the upper surface from the outside, or the bottle cap can be extended upward from the lower surface to achieve effective welding, or stuck in the opening to weld the upper and lower surfaces and the cross section at the same time. In short, the sealing member 24 is welded to the wrapping layer, thereby greatly improving the sealing effect.

[0062] The sealing member 24 includes a bottle cap or a pressing film;

[0063] The composite packaging material adopts conventional paper-based composite packaging materials, which are used for packaging materials of fluid or semi-fluid food, solid, etc.

[0064] The opening 18 has a corner, thereby solving the problem of stress concentration at the corner. As an extension, the opening 18 may not have a corner.

[0065] The edge of the sealing member 24 is automatically sealed and welded with the outer wrapping layer 22, the cross-section wrapping layer 20 and / or the inner wrapping layer 21 on the production line;

[0066] The cross-section portion 23 and the cross-section wrapping layer 20, the upper surface of the sealing member 24 and the outer wrapping layer 22, and / or the lower surface of the sealing member 24 and the inner wrapping layer 21 are automatically sealed and welded on the production line;

[0067] As an extended protection, the edge of the sealing member 24 is automatically sealed and welded with the outer wrapping layer 22, the cross-section wrapping layer 20 and / or the inner wrapping layer 21 on the production line, thereby realizing assembly line operation.

[0068] The composite surface of the outer wrapping layer 22, the cross-section wrapping layer 20 and / or the inner wrapping layer 21 and the corresponding end face portion 1 is weldable, thereby achieving a welding connection;

[0069] As an extended protection, on the end face portion 1, the outer wrapping layer 22, the cross-section wrapping layer 20 and / or the inner wrapping layer 21 are melted by filling with glue or bonded by bonding strips with a C-shaped (including U-shaped, etc.) lip;

[0070] The cross-section wrapping layer 20 is a PE strip or a PP strip or the like.

[0071] The semi-finished product of this embodiment is folded with the above-mentioned composite packaging material before being filled with liquid or gas or adding solid.

[0072] The finished product of this embodiment is formed by folding the above-mentioned semi-finished products.

[0074] Its main components, the processing equipment includes a base part 25, which is not limited to the structure of the drawing, and can be a frame or a box, etc. A lower mold 38 is arranged on the base part 25, which can be integrated with the base part 25 or separated, and a welding head 31 is arranged on the lower mold 38. The lower mold 38 and the lower contact surface 34 of the welding head 31 are relatively movable, so as to clamp or release the composite packaging material 26 to be sealed; Figure 3-6 Although the reality is that the welding head is lifted, it can also be the other way around, driving the lower mold to lift, and the driving component can be a hydraulic cylinder, an electric cylinder or other driving components.

[0075] The lower contact surface 34 has a receiving groove 35; it can be a flow channel to better cooperate with the injection molding seal. Of course, it is not necessary to use a groove.

[0076] The lower contact surface 34 has a central mandrel 37 inserted into the opening 18, thereby limiting the range of the welding wrap layer opening to the hollow.

[0077] A support part 28 is arranged on the base part 25; it can be a gantry or a single arm or other structure, and can be set up by lifting. The composite packaging material in the figure is a sheet material. Of course, if it becomes a semi-finished product, it also constitutes the same, which can be imagined.

[0078] As a further introduction to the structure, an upper frame body 27 is respectively provided on the bracket part 28, a guide upright sleeve 30 or other equivalent guide structure is provided on the upper frame body 27, and a lifting part 33 is provided in the guide upright sleeve 30; thereby realizing the lifting operation.

[0079] The welding head 31 is below the lifting part 33;

[0080] An upper top portion 29 is disposed above the upper frame 27; the two can be integral or separate.

[0081] A power unit 32 for driving a lifting unit 33 is provided on the upper frame 27 and may be hydraulically or electrically driven;

[0082] As an injection flow channel, the welding head 31 has a pouring channel 36 , and the pouring channel 36 is connected to the receiving groove 35 .

[0083] As a working principle, a sheet-shaped composite packaging material 26 (which may also be a folded state in which the side walls of the end face portion 1, the side portion A2, and the side portion B3 are folded) is fed onto the lower mold 38, and the lifting portion 33 realizes the lowering of the welding head 31, and the lower contact surface 34 is pressed onto the end face portion 1.

[0084] Of course, the guide upright sleeve 30 can be filled with molten glue, and the lifting part 33 can be used to squeeze the molten glue through the casting channel 36 into the receiving channel 35 by the counterweight screw, so as to realize the limited envelope range at the central core shaft 37.

[0085] The present invention is fully described for a clearer disclosure, and the prior art will not be listed one by one.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it; although the utility model is described in detail with reference to the above embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above embodiments, or replace some of the technical features therein with equivalents; it is obvious for those skilled in the art to combine multiple technical solutions of the utility model.
