Container for fluid substance

专利摘要:
The invention relates to packages intended to contain and pour out a fluid product required for one-time use. The purpose of the invention is to improve the usability. The package contains a rigid flat sheet 1 and a flexible sheet 2 attached thereto, between which a fluid chamber is formed. A fracture line is formed along the transverse axis of the flat sheet, on which a protruding element 5 is placed, made symmetrical about the breaking line and asymmetrical about the longitudinal axis of sheet 1. The breaking line serves as a guide line for controlled breaking of the rigid sheet when the package is folded into a V shape , while the stress is concentrated at the top of the protruding element due to the gain in strength on the lever arm η equal to the distance of the top from the bending axis passing along the surface of the rigid gloss sheet. An asymmetrical semi-pyramidal protruding element concentrates the bending stress at the top, causing the flat sheet to break, forming an outlet. The package may contain several chambers and a corresponding number of protruding elements placed above them.

Claims (8)
[1]
Claim
1. Packaging for a fluid substance containing a rigid flat sheet and a flexible sheet attached to one of the surfaces of the rigid sheet along its perimeter with the formation of a fluid chamber between them; on the rigid sheet along its transverse axis, a fault line and a protruding element are formed - on the fault line section for local concentration of increased stress in the rigid sheet with V-folding of the package and the formation of the outlet, while the protruding element 5 is made symmetrical with respect to the fault line, and its apex is located on the latter, characterized in that, in order to improve ease of use, the protruding element is located asymmetrically symmetrically relative to the longitudinal axis of the flat sheet.
[2]
2. Packaging according to claim 1, characterized in that the flat sheet contains an insulating material, which is foil.
fifteen
[3]
3. Packaging according to Claim. 1, with regard to that. that the flat sheet contains an insulating material, which is plastic.
[4]
4. Packaging according to claim 1, characterized in that the flat sheet contains two insulators
20 ional materials - foil and plastic.
[5]
5. The package according to claim 1, characterized in that it contains additional protruding elements located on the fault line.
25
[6]
6. Installation according to claim 1, characterized in that the protruding element in a vertical section passing through the fault line has a pointed profile.
[7]
7. Packaging according to claim 1, characterized
30 in that the flexible sheet forms an additional chamber located adjacent to the existing one, the package having an additional protruding element located on the fault line above the additional chamber 35, the configuration of the additional protruding element repeating the configuration of the existing one.
[8]
8. Packing pops 1 and 7, distinguishing 40 with the fact that each protruding element has a vertical wall located perpendicular to the fault line.
