Background of invention

The present invention relates to the method forming the pocket for dispensing viscous material.

Cohesive material can comprise sealing agent, glue, tackiness agent, glaze, seam sealer, grout and glue composition. Generally speaking, by this kind of cohesive material wrapping body, storage or commercialization in the cardboard packaging being suitable for loading in extrusion equipment such as caulking gun or plastic dispenser or cartridge case. These cohesive materials comprise for building the organic silicon sealant with Structural application and seam sealer. Some in these compositions are called as room temperature vulcanizable (RTV) composition. They can comprise the organo-siloxanes polymer of moisture-curable, filler and condensation cure catalyst. When being used as sealing agent, these compositions can in the pipe that do not pass through at moisture of wrapping body and be applied over base material by extruding from wrapping body pipe.

There is the difficulty relevant to these containers. Such as, some materials are sold for loading seam sealer divider or rifle in cartridge case. Divider or rifle be other must buy, store, the cleaning and article of part maintenance as caulking process. Divider or rifle may be heavy and be difficult to operation, especially true in the restricted clearance of the buildings built. In addition, partitioning device may require significant hand-power, which increases distribution and lays the challenge of clean bead of sealant grain.

In one approach, a certain amount of sealing agent is directly pressed onto crack to seal this region when drying from distribution piping or cartridge case. Generally speaking, the material that distribution piping or cartridge case comprise is by more than the amount needed for specific seal operation. Usually after the amount needed for distribution, some tube portions not used are retained. The distribution piping with unused portion is abandoned or preserves and is used for following use. Abandon and it is uneconomic and may not wish very much for environmental factors. Not can be used for the known recovery method of commercially available various encapsulant composition at present.

If not abandoning the container with remaining sealing agent, then must be covered to preserve material and be used for following use when not solidifying.But sealing agent may comprise and will evaporate the volatile constituent making residual materials solidify. Other sealing agents may solidify from being exposed to aerial oxygen. And unless container is suitably closed again, otherwise residual materials will be lost.

Embodiment 1

Evaluate wrapping body sample to determine the design of dispensing viscous material.

Sample is by transparent polypropyleneWrapping body, thin (< 1mm) black polypropylene and polyethylene sheets and acrylic resin film (< 1mm) form. Form sheet material and following heat seal becomes wrapping body shape: first cutting has the top exceeding size and the bottom rectangle of triangle shaped tip, and with triangle shaped tip heat seal together with side, sheet is formed nozzle. Some wrapping bodies gusset plate (gusset) is formed. Gusset plate is by folding film on packaging side and bottom and formed.

From wrapping body, excessive material is excised after shaping. Each packaging body material is filled and then heat seal forms sealing. The length of wrapping body is about 4cm-20cm, and width is about 2cm-15cm and thickness (being filled with material) is about 0.5cm-2cm. Wrapping body acrylic acid or the like seam sealer or organic silicon sealant are filled.

Assemble valuator group from each wrapping body of the sequence evaluation of 20-30. Evaluate content integrity and the material easiness compressed and control property of wrapping body. In evaluation, before dispensing materials, each wrapping body is observed in group's naked eyes and sense of touch. Then group member folds each wrapping body to compress its content. The easiness that control material pearl grain is pressed onto on test card cardboard is observed by group. Any failure in wrapping body integrity is also observed by group.

Evaluate the wrapping body for distributing acrylic acid or the like seam sealer and organic silicon sealant. For the wrapping body of each structure, group puts into practice repeated dispensing. Then group ratifies to select the wrapping body for next step is evaluated. Use the successful wrapping body of the latent structure according to the successful wrapping body that certainly must evaluate round in advance, repeat this process.

Group identifies not to be had useful materials to fill completely, does not form circular hole for extruding even pearl grain and the enough soft wrapping body design to fill completely. Some extrude fault, and by changing, nozzle angle and wrapping body length solve, for evaluation round subsequently. The design of some first runs was observed to thin and made to need the material pearl grain of precise controlling to distribute continuous and derivable. This solves in the following manner: (1) manufactures a surface of wrapping body with harder plastics sheet, and (2) change user's interaction so that wrapping body folds the distribution pattern providing even harder along crease length.

Some designs are noted as had thin film. Adopting these wrapping bodies, material resists and slides in wrapping body, therefore makes it difficult to extrude completely wrapping body content. The wrapping body of this problem gusset plate design keeps simultaneously or reduces wrapping body internal surface area solving to increase wrapping body volume.

Crease semirigid plastics backing for wrapping body is confirmed as holding the material of desirable amount and easily folding the preferably design for distributing. Totally it is produced by size wrapping body (7cmx5cmx1.5cm), so that extruding material completely with this wrapping body of manual manipulation.The distributer nozzle selected has longer (2cm) and narrower (1cm) nozzle, does not have nozzle variant to allow wrapping body extruding. And the wrapping body design selected has gusset plate in side, adds volume and makes internal surface area minimumization simultaneously so that can by a finger compression dispensing materials.

Carry out another campaign and determine the wrapping body preferably implemented with regard to sealing agent bead form. Criteria beads grain is defined as the sealing agent settling of circular cross section.

First the wrapping body tested only has top-film pocket and thicker base material sidewall. Thicker material sidewall is folded to form nozzle. But, the nozzle formed by the sidewall folded is soft and forms uneven pearl grain.Pearl grain cross section is by from thin horizontal rhombic (horizontaldiamond). Then, after a while in distribution, pearl grain cross section is formed with unacceptable thin vertical rhombus (verticaldiamond). In addition, top-film forms sharper folding and crease by nozzle so that cross section is more uneven.

In the test of this embodiment, semi-rigid material is added near wrapping body toe end a sidewall. In these embodiments, when harder material sidewall fold along its longitudinal axis extrude pocket time, semi-rigid material bends to U shape substantially in a controlled manner and extrudes shape (U-expressingshape). U shape extrude shape guarantee cross section half evenly and round, and restriction flexible sidewall edge to provide the extrusion pearl grain of all even circle.
