    • A dual chamber sachet with a dispensing outlet can be made in a form/fill sequence by attaching the dispensing outlet to the film that is to form the chamber divider wall followed by attaching films that are to form the outer walls of the sachet to the dispensing outlet. The upper and side lateral edges of the sachet then are sealed together to produce a sachet with an open bottom end. The sachet can be produced from three film sources, two film sources with the outer walls being formed from a single film, or from a single film formed into a W-shape. The sachet preferably is filled through the open bottom end and the bottom end then sealed. However the sachet can be top filled through the nozzle. The sachets then are severed one from the other by cutting along a lateral seal and packed into a carton, or preformatted along a lateral seal and cut to produce a string of a set number of sachets. The sachets can have a single use dispensing outlet or a reclosable dispensing outlet. Larger sachets will have a reclosable dispensing outlet.
    • 具有分配出口的双室小袋可以通过将分配出口附接到形成室分隔壁的膜,然后将用于形成小袋的外壁的膜附着到分配器的形式/填充顺序 出口。 然后将小袋的上侧和侧边缘密封在一起以产生具有开放底端的小袋。 小袋可以由三个胶片来源制成,两个胶片来源,其外壁由单一膜形成,或者由形成为W形的单个膜形成。 小袋优选地通过敞开的底端填充,然后将底端密封。 然而,小袋可以通过喷嘴顶部填充。 然后通过沿侧向密封切割并将其包装成纸箱,或者沿着侧向密封件预先形成并切割以产生一定数量的小袋的串,将小袋从另一个切断。 小袋可以具有单次使用分配出口或可重新闭合的分配出口。 较大的小袋将有一个可重新闭合的分配出口。

    • There is disclosed a closure comprised of a valve, a base unit and an upper unit. The base unit has a base surface with a peripheral skirt. The base surface has an aperture with a cylindrical section extending above and below the base surface. The cylindrical section has an aperture therethrough. The upper unit has an upper surface and an aperture adapted to align with the aperture of the cylindrical section of said base unit. The upper unit has a lid to cover the apertures in the base unit cylindrical section and the upper unit. A lid inner top surface has two projecting seals, one to maintain the valve closed when the lid is closed and the other to provide a seal when the lid is closed. and a latch mechanism attaches the base unit to the upper unit. A preferred latch mechanism comprises a projection and an interfitting recess, one being on the base section and the other on the upper section. The lid top surface preferably has an essential horizontal top surface. In a preferred embodiment the valve is a polymeric valve located in the aperture between the base unit and the upper unit and held in place by contact with both the base unit and the upper unit. The rheology of the product in the container and the characteristics of the valve are coordinated so that the product will be fully contained by the valve regardless of the orientation of the container, including being inverted.
    • 公开了一种由阀门,基座单元和上部单元构成的封闭件。 基座单元具有带有周边裙部的基面。 基面具有孔,其具有在基底表面上方和下方延伸的圆柱形部分。 圆柱形部分具有穿过其中的孔。 上部单元具有适于与所述基座单元的圆柱形部分的孔对准的上表面和孔。 上部单元具有覆盖基部单元圆柱形部分和上部单元中的孔的盖。 盖内表面具有两个突出的密封件,一个用于在盖子关闭时保持阀门关闭,另一个在盖子关闭时提供密封。 并且闩锁机构将基座单元附接到上部单元。 优选的闩锁机构包括突起和相互配合的凹槽,一个在基部上,另一个在上部。 盖顶表面优选具有基本的水平顶面。 在优选实施例中,阀是位于基座单元和上部单元之间的孔中的聚合物阀,并且通过与基座单元和上部单元两者接触而保持就位。 容器中的产品的流变性和阀的特性被协调,使得产品将被阀完全容纳,而不管容器的取向如何,包括倒置。
