Abstract
There is provided a pack for a product (12) to facilitate the dispensing of a liquid or particulate matter emanating from the product via a first openable portion (17). The pack comprises two films (13, 14) sealed together about a periphery to define a volume in which the product (12) is contained. The films at the openable portion (17) can be peeled apart in order to create an opening, but the size of the opening is limited by the provision of stronger connections (52) on either side of the openable portion.
Claims19
A pack comprising a sealed package containing a squeezable product, the package having a first openable portion and being at least partially flexible to enable squeezing of the product to facilitate dispensing of a liquid or particulate material emanating from the product via the first openable portion once opened, wherein the package comprises one or more films which are fluid-tight and which fully enclose a volume in which the product is sealingly retained, wherein said one or more films comprises a flexible first film and a second film, which films are sealingly joined to each other about a periphery thereby forming a peripheral seal fully enclosing said volume in which the product is sealingly retained, wherein the first openable portion comprises at least one of the films having a grippable tab which can be manipulated to peel apart the joint between the films, wherein the first openable portion comprises a first seal portion comprising a first side and a second side, wherein the first seal portion is relatively weak compared to a first second seal portion on the first side of the first seal portion and a second second seal portion on the second side of the first seal portion, whereby the second seal portions resist separation thereby to limit the first openable portion to a first predetermined size, wherein the package has a second openable portion at a position spaced from the first openable portion, the second openable portion comprising at least one of the films having a further grippable tab which can be manipulated to peel apart the joint between the films, wherein the second openable portion comprises a third seal portion comprising a first side and a second side, wherein the third seal portion is relatively weak compared to a first fourth seal portion on the first side of the third seal portion and a second fourth seal portion on the second side of the third seal portion, whereby the fourth seal portions resist separation thereby to limit the second openable portion to a second predetermined size, wherein the second predetermined size is greater than said first predetermined size such that the first predetermined size beyond which the films are resisted from separation prevents passage of the squeezable product through the first openable portion and wherein the second predetermined size by which the films are permitted to separate permits the passage of the squeezable product through the second openable portion, and wherein the first second seal portion is contiguous with the first fourth seal portion, the second second seal portion is contiguous with the second fourth seal portion, and the second and fourth seal portions are spaced from said peripheral seal.
A pack comprising a sealed package containing a squeezable product, the package having a first openable portion and being at least partially flexible to enable squeezing of the product to facilitate dispensing of a liquid or particulate material emanating from the product via the first openable portion once opened, wherein the package comprises one or more films which are fluid-tight and which fully enclose a volume in which the product is sealingly retained, wherein said one or more films comprises a flexible first film and a second film, which films are sealingly joined to each other about a periphery thereby forming a peripheral seal fully enclosing said volume in which the product is sealingly retained, wherein the first openable portion comprises at least one of the films having a grippable tab which can be manipulated to peel apart the joint between the films, wherein the first openable portion comprises a first seal portion comprising a first side and a second side, wherein the first seal portion is relatively weak compared to a first second seal portion on the first side of the first seal portion and a second second seal portion on the second side of the first seal portion, whereby the second seal portions resist separation thereby to limit the first openable portion to a first predetermined size;
- wherein the package has a second openable portion at a position spaced from the first openable portion, the second openable portion comprising at least one of the films having a further grippable tab which can be manipulated to peel apart the joint between the films;
- wherein the second openable portion comprises a third seal portion comprising a first side and a second side, wherein the third seal portion is relatively weak compared to a first fourth seal portion on the first side of the third seal portion and a second fourth seal portion on the second side of the third seal portion, whereby the fourth seal portions resist separation thereby to limit the second openable portion to a second predetermined size;
- wherein the second predetermined size is greater than said first predetermined size such that the first predetermined size beyond which the films are resisted from separation prevents passage of the squeezable product through the first openable portion and wherein the second predetermined size by which the films are permitted to separate permits the passage of the squeezable product through the second openable portion;
- wherein the first and third seal portions are part of the peripheral seal between the two films to enclose said volume and the second and fourth seal portions are in the form of additional joints between the two films;
- and
- wherein the first second seal portion is contiguous with the first fourth seal portion, and the second second seal portion is contiguous with the second fourth seal portion.
