Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to disposable gloves made from a pair of mutually sealed and overlapping plates of flexible sheet material, such as plastic film. Such gloves are impermeable to liquids and may be used as protective gloves (eg, of the type disclosed in European Patent Specification No. 102.992).

Such gloves usually don't fit very well, so
I don't feel well enough to wear it.

It is therefore an object of the present invention to provide a glove of the above type that fits well and is comfortable to wear.

Accordingly, the present invention provides a disposable glove made of a set of shaped, stacked flat plates, the flat plates being made of a soft sheet material, the glove covering the palm, fingers, thumb of a person's hand, and a wrist or sleeve consisting of a palm part, four finger parts, a thumb part, and a wrist or sleeve part for each wrist to be placed in, and which extends beyond the palm part in the direction opposite to the finger parts. The overlapping inner walls along the ends of the openings formed at the ends of the parts are sealed together, and the glove according to the invention has a width of at least one finger part when the glove is in a flat state. ,
expanding from a first size at a first position adjacent to the palm part to a second maximum size at a position intermediate between the first position and the tip of the finger part; Features. This is in contrast to conventional disposable gloves, in which the finger portions have an apparently tapered shape;
It has been found that it is more convenient to use because the maximum width of one or more of the finger sections is located to accommodate the knuckles of the user's fingers. Therefore, when you bend your fingers like in conventional gloves, which have a tapered finger section, your fingers no longer slip out from the finger section.

The width may widen from the first size to the second size in any part of the finger, but at least the part of the finger that includes the index finger, middle finger, and ring finger is effective.

Adjacent ends of adjacent finger sections join at the base of the fingers adjacent the palm section, substantially as in conventional gloves of the current type. However, in a preferred embodiment of the glove according to the invention, the adjacent finger sections maintain a constant spacing from each other at the inner ends of the finger sections.

For this reason, it has been found that the gloves fit better. To avoid sharp bending angles that could tear the soft sheet material, the bases of the adjacent and spaced finger sections are concave curves that are essentially circular arcs.

The fit of the glove according to the invention is improved by increasing the angle between the longitudinal axis of the thumb section and the longitudinal axis of the middle finger section. This angle may be, for example, between 40'' and 60°.

Furthermore, in the flat state of the glove, the width of the wrist or sleeve may decrease from an initial wrist or sleeve end dimension to a minimum dimension adjacent the palm portion.

The soft sheet material from which this glove is made may be of suitable liquid impermeability, such that it is inexpensive enough to be used in disposable gloves.
Sheet material is fine. In many cases, such flexible sheet materials are plastic films, with overlapping plastic inner walls joined together by heat sealing.

The invention will now be further described with reference to the drawings, which schematically show embodiments of the glove according to the invention.

The glove shown in the figure has a palm portion 10, a wrist or sleeve portion 11, a thumb portion 12, and portions of the index, middle, ring, and little fingers 13°14.15;
It consists of 6.

The width of the finger portion 14 ranges from the width W at the base of the finger to the maximum width Wm at a position midway between the base and tip of the finger portion 14.
It is larger than ax. Which finger part from 13 to 16,
Preferably all finger parts 13 to 15 have the same shape. The finger portions 13-16 extending from the palm portion 10 in a distributed relationship maintain a substantially constant spacing at the base of the finger portions, and adjacent finger portions are connected by concave curved portions. , preferably in the form of an arc with radii R, , R1 and R3. Similarly, the thumb section I2 and the finger section 13 are connected by a concave curved section with radius R4.

The wrist or sleeve portion 11 is funnel-shaped, ie tapering from its end 17 into the palm portion 10. The thumb portion and the middle finger portion 14 are spread out such that the angle between their respective longitudinal axes is α.

The glove shown in the figure is made from two overlapping planar plastic films joined by heat sealing from the end 17 of the sleeve portion 11 along the glove shape, leaving the sleeve opening open.

Examples The gloves described above are made in, for example, eight different sizes. The length from the entrance 17 of the sleeve part 11 to the tip of the middle finger part 14 is 323 m in various sizes.
, 336M, 351m, 368mm
.

They are 386mm, 404m, 423m, and 444m.

As an example, the size defined as "large" is the length of 444 cranes, and the width W and maximum width Wmax of the finger part 14 are 44 angles and 47 mm.
It's a crane. The maximum width of the sleeve portion of the entrance 17 and the minimum internal width of the sleeve portion are 183 mm and 137 mm, respectively.
mm, and the angle α is approximately 50”.

The glove of the invention is preferably made of a polymeric material of the type described in European Patent Specification No. 102,992, incorporated by reference. A particularly preferred class of polymeric materials mentioned in the European patent specification indicated above is 4
C2~.substituted with up to hydroxy groups. Alkenes and 02~. or copolymers of alkenes of C1 to . substituted with up to 4 hydroxy groups. The alkene homopolymer oCZ~5 alkene is preferably ethylene. A particularly useful copolymer is vinyl alcohol-ethylene copolymer, in which vinyl alcohol
~80 mol% ethylene 20-60 mol%, especially vinyl alcohol 65-75 mol%, ethylene 25-35 mol%
It is preferable to include mol%.

Such materials are preferably laminated between layers of other polymers, especially polyethylene. For example, polyethylene/
It is a vinyl alcohol-ethylene copolymer/polyethylene laminate.
