Abstract
ABSTRACT OF THE INVENTION
BEVERAGE SACHET
A beverage sachet of laminate material with a liquid-tight inner layer of thermoplastic plastice material and an intermediate layer impermeable by aromatic substances; the sachet (10) comprising two oblong wall panels (11, 12) connected with each other by welded lateral edge seams (19, 20) along their longer edges (17, 18) and an inserted bass panel (13), folded inwardly in V-shape in the region of two adjacent shorter edges (21) of the wall panels and welded to each wall panel by a respective U-shaped welded seam (22, 23). The same (22, 23) are each of substantially greater width than the lateral edge seams (19, 20) and each consist of a transverse section (24, 25) extending along the shorter edge (21) of the respective wall panel and arm sections (26, 26' and 27, 27'), which extend parallel to the lateral edge seams (19, 20) and which, in the region of the gusset formed by the inner folded edge (28) of the base panel (13) terminate in outwardly directed tapered portions (29, 29' and 30, 30') at the inner edges of the lateral edge seams (19, 20).

The sachst consists of two oblong film webs connected with each other by longitudinsl welding seams extending along their longsr edgsa and of an lnaerted baaa piBC8~ fOldBd inwardly in V-~hape in the region of two adJacent shorter edges of the webs and weldsd to esch web by meens of e respectivs U-ahapsd welded ssam.
ln enother known beverage sachst of this kind, which ia de~cribed in German ~F ed.

According to the preeent invention there ia prov$ded a bevsrage aachet of laminate aheet material with a layer of thermo-plsstic-plaatice matarial facing inwardly of the aachat and an ad-~acent layer of vapour-impermeebls material, the eachet ^ompriaing two oblong wall pansle connected together at their longer edgas by welded lateral edge seama and a baea panel folded to pro;HCt betwaen the wall pansls in the region of two edjacent ahorter edgea thersof and conneoted to each of tha wall panela at eaid longer and shorter edgee by e respective subatantially U-ahaped welded seem, which ie of greater width than either of the lateral edge seam~ and which com-pri~es a base section extending along eaid shorter edge of the rbsp-ective wall penel and two arm eections extending parellel to ths laterel edge eaame and terminating in the region of the fold of the ~sse panel in tepered portions connecting with the leterel edge aesms.
In a beverage l3schet conatruction embodying the present invantion, the angled eeame and aupporting eeems typical of the known beverege eachets are redundant. The unfolding of ths base panel during filling and etabiliSy of the aachet are echieved by the form of the U-shaped seams connecting the base psnel to the well panela, whe~eby the erm l3ections of these aeams extend parellel to the lateral edge aeams, are aubatantielly wider than tha lateral edge seams~ have tapered portionl3 in the reg~on of gusaets formed by .
