FIELD OF THE INVENTION

This invention relates to the general field of packaging, in particular single-dose or single-use packaging that is designed to store and dispatch the product indoors.

BACKGROUND OF THE INVENTION

Single-dose containers are common in daily life, such as the food and beverage, cosmetic, pharmaceutical, and other industries.

Examples of single-dose containers include envelopes, tetra-pack packages, sachets, PET / plastic cups, or glass bottles, which have limitations. Envelopes do not have delivery holes, making them difficult to use. Also, envelopes often need to be twisted to open, which can cause additional challenge when shipping a product. Tetra-pack packages are used in the beverage industry and can store liquids, but require a straw for consumption. These are not appropriate for other types of products, such as creams, pastes, ointments and other slimy products that need to be easily

envelopes as they must be clearance holes,

The sachets are similar to twisted ones to open and lack clean and convenient features, which can lead to a frequency required to obtain the whisk product. PET / plastic cups with an additional tool or apparatus for contents in the plastic cup. Glass bottles are breakable and heavier, and cannot be used effectively for viscous or pasty products since those products cannot be easily dispensed by gravity or squeezing.

Most known single-dose containers have a lid or cover closure placed over an open end of the container or some type of seal to cover the open end. Many of these known packages have threaded necks that extend upward to receive a cap, and may also have a sealing edge at the end of the neck to hold a seal to cover the open end. Those containers with a seal often require an apparatus to pierce the seal, such as a pointed end on the inside of the lid. Removable seals can also be used, but such seals can be difficult to use.

DETAILED DESCRIPTION OF THE INVENTION

The embodiments of the present invention refer to a single dose container for storing and dispatching products. The products contained in the single-dose container are fluids, that is, powdery or liquid to pasty, such as liquids, pastes, creams, ointments, powder or granular products as well as other substances. Examples of such products include concentrated drinks, sun creams, polysporin ointment, toothpaste, ketchup, mayonnaise, mustard, drink crystals, sugar, and salt. The containers are versatile and can be used in the pharmaceutical, cosmetic, nutraceutical, homeopathy, natural health, food and beverage industries.

Referring to Figure 1, a disposable container, in accordance with an embodiment of the present invention, is indicated by reference number 10. Flexible body 20 of container 10 is made of a material

<img file="MX343754B_D0009.tif" />

foldable so that the product contained within flexible body 20 can be completely dispensed.

The material for the flexible body 20 can be any type of flexible, foldable material of varying thickness, such as aluminum. Other materials that can be used include other formable metal alloys, various laminates, ethylene vinyl alcohol (EVOH) plastic barrier laminates

The flexible body material 20 can be sterilized for use with products that need to be sterile. Because various materials can be used to make the container

10, the container 10 can be hot fill, cold fill, dry fill and / or sterilized for aseptic filling.

The disposable container 10 has the first end 30 which is sealed by joining the inner sides of the inner surfaces of the flexible body 20 using known techniques, such as hot air, hot jaws, high frequency welding, or ultrasonic sealing. The sealing of the first end 30 in this way configures the container 10 in the form of a flexible skirt, which under pressure exerted by the fingers of the hand, can be tightened so that the product contained inside said skirt can be pushed out.

<img file="MX343754B_D0010.tif" />

The second end 40 has protrusion 44 with a generally flat sealing edge 46 (not shown in Figure 1) on which the container 10 can rest in an upright position.

Referring to Figure 4, the first end 30 and the second end 40 are at opposite ends of the container 10 along the longitudinal axis 50. Body 20 additionally includes a first side wall 90 and a second side wall 92, which define an interior cavity that can be sealed at the first end 30 by joining a first interior side 94 of the first side wall 90, said first inner side is the inner surface of said body 20, to an opposite inner side 96 of the second side wall 92, said opposite inner side is the inner surface of said body.

Referring to Figures 2 and 5, the second end 40 has the support 42 and the protrusion 44. The second end 40 does not contain a neck extending from the support 42. The support 42 and the protrusion 44 are contiguous to each other. The protrusion 44 defines the clearance hole 48 and has the sealing edge 46. Dispatch hole 48 is positioned at approximately the center of boss 44 and sealing edge 46 defines the outer ring of dispatch hole 48 contained in

<img file="MX343754B_D0011.tif" />

approximately the center of the boss 44. Dispatch hole 48 is represented as a circle, but may also be a slit, square, diamond, rectangle, or other dimensioned opening.

Support 42 connects second end 40 to flexible body 20 of container 10. For aesthetic and practical reasons, side wall 60 of flexible body 20 may be flush with support 42 of second end 40. In other words, side wall 60 it is a continuation of the outer surface of the support 42. The second end 40 can be secured to the flexible body 42 using methods known in the art, such as compression molding or high-frequency welding. Flange 62 indicates the point of attachment between side wall 60 and support 42, with side wall 60 overlapping support 42, resulting in flange 62 being a rounded edge where flexible body 20 meets the second end 40.

Axis 50 is an axis of symmetry (rotational symmetry), so that boss 44 and sealing edge 46 enclose axis 50 and axis 50 passes approximately through the center of dispatch hole 48.

The second end 40 is a continuous piece of the same material and is semi-rigid. The material can be

<img file="MX343754B_D0012.tif" />

polyethylene, polypropylene, or other polymer compound in clear or colored form. Second end 40 can be formed on support 42 and protrusion 44 using methods known in the art, such as compression molding or injection molding.

The support 42 and protrusion 44 of container 10 can be of various sizes and shapes depending on the product to be contained in container 10. Dispatch hole 48 in the center of protrusion 44 can also be of different sizes depending on the product. .

Flexible body 20 typically has a greater dimension along axis 50 compared to the width of flexible body 20. Flexible body 20 is symmetrical relative to a plane passing through axis 50. Second end 40 has a height between flange 62 and sealing edge 4 0 which is not more than 0.5 cm and represents approximately 0.03% to approximately 1.0% of the length of the container 10 along axis 50.

The opposite end support 42 is established at approximately an angle of 60 ° relative to a line parallel to axis 50 and extending directly from the side wall 60 of flexible body 20, said hypothetical line indicated by reference number 90. Alternatively, the

<img file="MX343754B_D0013.tif" />

Support 42 can be set at any angle between.

about 20% and about 70% relative to the hypothetical line 90. The height of the bump 44 is generally between about 0.05 cm and about 0.25 cm.

Figure 3 is a top view of container 10, without a seal membrane covering the delivery hole.

48. Dispatch hole 48 is represented as a circle approximately in the center of support 42. Sealing edge 46 is depicted as an inner ring that encloses dispatch hole 48.

The support 42 is represented as an outer circle enclosing the sealing edge 46. Figure 3 is representative of the diameter of the clearance hole 48 relative to the support 42 and the flexible body 20. In the embodiment shown in Figure 3, the Dispatch hole 48 diameter is approximately 25% of support surface 42, but more commonly it is between 20% and 35% and may be between 5% and 65% of support surface 42.

<img file="MX343754B_D0014.tif" />

Flange 82 extends from seal membrane 80. Flange portion 82 can be made in various lengths.

The flange portion 82 is folded back against the top of the seal membrane 80 so that it extends substantially parallel to the plane of the seal membrane 82.

Seal membrane 80 is removably attached to seal edge 46, which prevents product in container 10 from leaking before the user dispatches product from container 10. Seal membrane 80 is removably fixed using methods known in the art, such as the use of heat or an adhesion compound. Seal membrane 80 can be removed by peeling seal membrane 80 away from sealing edge 46. The user can easily remove the seal membrane 80 from the container 10 by pulling the flange portion 82 away from the seal membrane 80 and through the plane of the seal membrane 80.

In an alternative embodiment, the flange portion can extend radially downward away from the boss 44 and along the support 42 toward the side wall 60 of the flexible body 20.

The present invention is easy to use, quick and easy to open and dispenses the product contained therein

<img file="MX343754B_D0015.tif" />

quickly due to the flexible and folding wall of the flexible body. By eliminating the need for a threaded neck and lid closure, the disposable container described here uses a minimal amount of raw materials, resulting in less environmental waste, reduced weight for the disposable container, and reduced costs of shipping the container and the manufacture of the container. The present invention is a versatile type of container that covers a wide range of fields of application a wide range of products

The embodiments described above have been provided as examples, for clarity in understanding the invention.
