Description

Disposable contact lens packaging bag

The technical field is as follows:

the utility model relates to a disposable contact lens packaging bag.

Background art:

with the increasing expansion of the contact lens market and the popularization of daily disposable products, disposable contact lens packages are favored by various manufacturers, and currently, boat-shaped vessels made of plastic materials such as polypropylene are generally used in the market, a preserving fluid is injected into boat-shaped grooves, lenses are placed in the boat-shaped grooves, and then a metal composite film is covered on the boat-shaped grooves through thermoplastic processing to form the contact lens packages. However, such a package is relatively expensive, and if the force is too large during transportation, the boat-shaped groove is easily deformed, which affects the appearance of the product package and the sales of the product package, and when the force is too large, the package is damaged and directly causes loss.

In order to prevent the above situation, some manufacturers produce a soft package, a space for storing the contact lenses is directly formed by two layers of metal composite films, and the contact lenses and the preserving fluid are placed in the space, so that the production cost is reduced, and the contact lenses are convenient to transport and carry. However, such packages are generally opaque, resulting in consumer visibility of the lenses in the package at the time of purchase, which is detrimental to the design of the purchase and does not allow quality inspection.

Under such circumstances, there is a need for a novel contact lens package that reduces the package size, effectively saves space, avoids damage to the package during shipping, and facilitates viewing and purchasing by consumers.

The invention content is as follows:

the utility model aims at improving on the basis of soft packing, realizing the advantage that the existing size is smaller and observing the function of the pattern of the lens simultaneously. The technical scheme is as follows:

a disposable contact lens package comprising: lower membrane 1 with cavity 3 covers the last membrane 2 of cavity, the material of lower membrane, last membrane is metal complex film, still includes: an observation window 5 is positioned on the upper film, and the observation window is just corresponding to the position of the concave cavity of the lower film; a transparent film 4 covering the observation window.

In the first preferred scheme, the transparent film is thick in the middle and thin at the periphery corresponding to the position of the observation window, and has the amplification effect of a convex lens.

Preferably, a small section of bulge 6 is arranged at the bonding position of the lower film and the upper film.

The contact lens package of the utility model has small size due to the design of the lower film groove, can effectively save space and is convenient for transportation and carrying; the package is soft material, and can effectively avoid being damaged in the transportation process; the package can facilitate retailer and consumer shopping and quality check.

Description of the drawings:

FIG. 1 is a front view of a contact lens package according to an embodiment; in the figure, 3 represents a cavity on the lower film, 5 represents a viewing window on the upper film, 6 represents a small projection on the bonding of the lower film and the upper film, 71 represents a first bonding seam of the lower film and the upper film, 72 represents a second bonding seam of the lower film and the upper film, 73 represents a third bonding seam of the lower film and the upper film, and 74 represents a fourth bonding seam of the lower film and the upper film; the bulge, the first bonding seam, the second bonding seam, the third bonding seam and the fourth bonding seam are located on the same plane, and the bulge direction is just opposite to the direction that the opening is gradually enlarged when the upper film and the lower film are torn.

FIG. 2 is a rear view of the contact lens package of the embodiment; in the figure, 3 denotes the cavity in the lower membrane.

FIG. 3 is a right side view of FIG. 1; in the figure, 1 represents the lower film, 2 represents the upper film, 3 represents the cavity on the lower film, and 4 represents the transparent film.

Fig. 4 is a schematic diagram showing the contact lens package of fig. 3 being torn away.

The specific implementation mode is as follows:

example (b):

a disposable contact lens package comprising: lower membrane 1 with cavity 3 covers the last membrane 2 of cavity, the material of lower membrane, last membrane is metal complex film, still includes: an observation window 5 is positioned on the upper film, and the observation window is just corresponding to the position of the concave cavity of the lower film; a transparent film 4 covering the observation window; the transparent film is thick in the middle and thin at the periphery corresponding to the position of the observation window, and has the amplification effect of a convex lens; the lower film and the upper film are bonded together, the concave cavity is covered with the transparent film, and a closed space is just formed and is used for containing lenses and preserving fluid; the bonding part of the lower film and the upper film consists of four bonding seams, namely a first bonding seam 71, a second bonding seam 72, a third bonding seam 73 and a fourth bonding seam 74, wherein a small section of bulge 6 is arranged at the center of the fourth bonding seam, and the bulge is in a semicircular shape in the embodiment and is used for preventing the package from being torn when the package is torn.

The material of the metal composite film can be aluminum foil, but is not limited to the aluminum foil; the transparent film is made of any one of polyvinyl chloride, transparent silica gel and polyethylene.

As can be seen from fig. 1 and 3, a part of the materials of the upper film and the lower film are not adhered together from the adhesion part of the lower film and the upper film to the top, when the packaging bag needs to be opened, the upper film or the lower film is easily lifted by one hand to be separated, as shown in fig. 4; then, starting from the protrusion, the bonding-out clutch is gradually bonded out, the upper film and the lower film are separated, and finally the inner lens is taken out.
