HOT WATER BOTTLES Filed 00tl, 1958 INVENTOR.
- 155;: 7073/. My 5 BY MM K n /40ENT 3,028,899 Patented Apr. 10, 1962 3,028,899 HOT WATER BOTTLES Josef Hiibl, Berggasse 16, Vienna IX, Austria Filed Oct. 1, 1958, Ser. No. 764,698 1 Claim. (Cl. 1502.1)
The invention relates to hot water bottles, and in particular to such bottles consisting of two flat, shaped blanks of thermoplastic sheet or foil material whose edges are welded together to form a hollow body. It is known to provide such bottles with a neck portion which is adapted to be rolled up and is held in the rolled-up state by means of a tongue extending from one side of the bottle over the rolled-up neck portion on to the other side of the bottle and is secured there.
The object of the invention is to make the closure of such hot water bottles pressure-tight, and for this purpose a bottle of the type specified hereinbefore is so constructed that the neck portion has an internally extending seal which is connected to the rim of the neck portion and to the weld seams of the neck portion, and is formed of two tabs which bear against the walls of the neck portion.
One embodiment of the invention will now be described by way of example, with reference to the accompanying diagrammatic drawing in which,
:FIG. 1 is a front view of a hot water bottle according to the invention,
FIG. 2 is a side view thereof,
FIG. 3 is also a side view, in which the neck portion is partly rolled-up,
FIG. 4 is a cross-section of the neck portion on a larger scale, showing the construction of the seal according to the invention in more detail, and
FIG. 5 is an enlarged sectional detail, taken substantially in the plane of the line 55 in FIG. 1.
The bottle portion 1 is provided with a neck portion 2, which forms a prolongation of the bottle portion and is made integral therewith. The bottle is formed by two like blanks of thermoplastic synthetic plastic sheet material of adequate strength, which are welded thermoplastically at the edge Zones, thus producing a bottle which is completely fiat when empty. Bead 4 forms the rim of the neck portion. A buckle 6 with adjustable centre bar 6 is fixed to one blank by loop 5 while a tongue 7 is fixed to the other blank. Two sealing tabs 8, which also consist of thermoplastic foil, extend into the interior of the neck portion and are welded thereto at the rim 4 and side seams 10, while their lower edges 11 are left free. Held by the loop 5, a carrying strap 12 extends as far as the neck rim 4.
When it is desired to fill the bottle with hot water or with ice water, it is gripped by the carrying strap 12 and water is poured in through the neck portion 2. In order to close the bottle, the neck portion 2 is rolled up into a words, a kind of fiap valve.
coil in the manner shown in FIG. 3, which causes the strap 12 to be folded to some extent. The neck portion coil is thus subjected to pressure from the interior, which promotes the sealing-tightness of the closure. Then the tongue 7 is folded towards the front over the coil and is fixed in the buckle 6. The seals 8 guarantee completely tight closure even if the container is subjected to considerable pressures acting from the exterior. It has been found advantageous to make the inner or facing sides of the sealing tabs 8 smooth, since this produces a labyrinth which will block the passage of the liquid, or in other In fact, a closure constructed in this way remains tight even if the filled bottle is subjected to extremely high pressure, which may happen if an invalid lies with his whole weight on the bottle.
It is important that the neck portion consist of two parts which lie completely fiat against one another when the bottle is empty, and not merely of a flat-pressed tube, for example, since the latter cannot be pressed together at the edge zones as strongly as is necessary for obtaining a tight closure. A tight closure cannot be achieved if there remain in the side regions of the rolled-up neck portion even the smallest passages through which water could trickle to the outside from the bottle when it is subjected to pressure.
What I claim is:
In a water bottle, the combination of a body portion and a neck integral therewith, said body portion and neck comprising a pair'of superposed flexible wall members having contiguous marginal edges secured together along the perimeter of the body portion and along opposite sides of said neck, said marginal edges of said wall members being separate from each other at the end of said neck to provide a mouth opening for the bottle, and a closure for said mouth opening comprising a pair of superposed.
flexible tabs disposed in said neck, said tabs having outer end edges secured to the separate edges of the respective wall members at said mouth opening, said tabs also having References Cited in the file of this patent UNITED STATES PATENTS 753,063 Goodridge Feb. 23, 1904 2,622,646 Miller Dec. 23, 1952 2,695,646 Van Wyk Nov. 30, 1954 2,798,522
