Description

[Detailed description of the invention] Food - Anamineguchi 4 y and low vXl force 3 Containers for products, beverages and other products, particularly those that contain oxygen (or other gases), In addition to airtight bank products and foods that are easily affected by air and light, Filling.

Cold” pack, frozen, aseptic processing, sterilization, retort, high temperature quick pack (H”> Ideal for packaging products such as beverages that have undergone ST) or other processing methods It is about a container. The containers of the invention can also be used, for example, for motor oil, industrial Expense products, medicines, wet or dry chemicals, detergents, automotive necessities Atomosphere-packed products, etc. cts).

Traditional containers, whether made of metal, glass, or paperboard, are also coated with paperboard, double-sided J-tings, chemically treated or waxed materials, and more. Various materials such as single-layer or multi-layer materials made of polymers and synthetic resins. However, each has its own drawbacks. Torineri, conventional containers have the advantage of strength. Instead, the amount of material is increased at the expense of thinness. Therefore, it is necessary to metal, relatively thick glass, or glass to obtain the required hardness, robustness, and unbreakability. It is common to use reamers or synthetic resin materials. However, to maximize the strength is also to maximize material costs. Places where the product must be protected from air In this case, plastics with high resistance can be used; Adding sufficient thickness to provide strength increases cost and increases the It cannot be said that the value is fully utilized. In the case of glass bottles, due to moisture and air Cool to contamination and internal pressure, or use heavy to resist breakage. You have to make sacrifices to increase the amount.

Metal cans are expensive to manufacture and always have functional problems, so they are no longer available today. It is no longer used much. For more modern cans made from rolled aluminum, use As a result of reducing the amount of material and making the can wall thinner, pins created by friction during the filling process were reduced. There is a skin that causes leakage from the hole. Cans with thin walls may also be used during transportation. or damage it.

Paperboard wrapped in a spiral or spiral shape with foil or polymer lining The resulting syntheses have been used quite extensively, and they also have drawbacks such as leakage. There is. Such spiral-wound synthesis can be used, for example, in light confectionery, frozen concentrated foods, and motors. It is used to contain oil, but it not only leaks due to capillary action but also gets twisted. There is skin that breaks and develops small holes. Such a can has a saw on its lower part. Is it necessary to add some additional information to that part, or is there a remainder δ1 that should be omitted if possible? In addition to requiring materials and processing steps, there is also the risk of leakage occurring from the joints.

8 Containers containing carbonated drinks must be filled with water to prevent them from bursting due to the internal pressure of the container. If you try to do that, the container has to be durable, which creates another problem. . In fact, bursting soda water glasses can cause injury and damage. Since this is a common problem despite Ruruko, we decided to develop a synthetic resin container. However, synthetic resin containers not only require a fairly thick wall, but also require a reinforced structure. It must have a structure.

The emergence of inexpensive containers that combine the perfection that consumers demand and expect from containers is long awaited. was.

Q-Kasami jU example 41 Natsutomo- Referring to FIG. 1, there is a general illustration of a rolling can according to the prior art. These are just a few examples of the many conventional containers for products, beverages and other semi-solid or liquid products. be. Such a container not only functions to protect the contents, but also to fill the contents into the can. Cans or containers may be dented or altered due to filling, transportation, distribution, or handling by consumers. A package that is structurally strong enough to resist deformation, rupture, or leakage. It must also have the functionality of a package. In many ways, a can is a container. It shows the technological level of the packaging industry, or even if it tries to reduce material costs. The current situation is that there are some unreasonableness caused by the shape, and it is difficult to do what you want. That is, It is made of rolled thin aluminum, and has a bead 1 on the side wall, a bottom 3 and a lid 5 on the top. In the case of cans with such structure, the thinness of the material is not suitable for the usual precursor, penocaging process. The floor has reached a level where even the slightest friction can cause small holes or leakage of raw contents. ing. Also, such a thin side wall 9 can easily break or constrict, or it can't get to that point. Both are easily scratched, resulting in unsightly dents and ruptures during normal handling. Resulting in. Therefore, the funeral structure, i.e. the structural and storage functions achieved with a single material technology, It is said that the progress of conventional containers, which try to combine them together, has already reached its limit. That would be fine.

4 Saishoumei-Φ1 [Mon-na summary The present invention utilizes a combination of unconventional technologies, materials and composite structures to meet the needs of the container. We offer low-cost and reliable containers that are different from conventional standard containers and can accomplish several functions. This is what we provide.

Simply put, the container according to the present invention has a barrier film layer (BA) that stores and protects the product. It has an inner container with a thin wall made of a material that forms the arrier. It is something that exists. The wall thickness of the inner container is such that it cannot be used as a normal container by itself. It's the thickness. Materials for forming such inner containers include polymers, synthetic resins, thin metal, glass, etc.

In this example, The container 15 has a so-called cup-like or barrel-like shape, and is flat or raised upward. bottom 17. Straight or sloped side wall 19 and ring-shaped ridge 25 The structure consists of a circumference 1M2+ extending radially outward from the large diameter portion 23 forming the has been completed. The inner container 15 may be transparent, translucent, or opaque. During ~ The container 15 is housed within the outer frame 13. The outer frame 13 is made by a generally known method. It has enough thickness and sturdiness to support and protect the sides and bottom of the inner container 15 at least. It is made of paperboard wrapped in a spiral or spiral shape. Middle container 15 and outer frame The shape of 13 can be of various geometries, but a tubular structure is most preferred. .

In the illustrated tubular container, the outer frame 13 has vertical side walls 27 . The bottom part is provided with a retracting part 29 directed inward, and -■ two parts. The margin 31 is slightly sloped, and there is a ring-shaped Rinon 25 is on board.

Therefore, the large diameter portion 23 of the medium container 15 expands over the outer frame 13 inside the outer frame 13. It is stored in. The outer frame 13 is open at its lower end, and the container 11 is placed in the outer frame 13. It has sufficient height so that there is a gap between the top surface and the bottom 17.

Although not shown, synthetic resin, polymer, foil, paper, or combinations of these materials may be used. A thin crotch made of composite material (hereinafter referred to as "synthetic material") protects the inner container and protects the exterior. The open bottom end of the outer frame may be closed for decoration.

Although not shown, the outer frame 13 is used to integrally connect the outer frame 13 and the inner container 15. Between the inner surface 33 of the inner container 15 and the outer wall 19 of the inner container 15 is a film made of an adhesive material or polyester. It is preferable to provide a mer film.

Other means may be used to integrally fix the outer frame 13 and the inner container 15. .

3 configuration M1 The construction of the inner container of the present invention includes not only thin metals and glass but also flexible synthetic materials. It is possible to use a wide variety of materials such as resins and polymers. The most suitable material is , a polymer that can sufficiently protect against oxygen, other gases, moisture, and light even if it is fairly thin. It is a highly durable barrier material.

A particularly suitable barrier material is Saran resin. The generic word Karan is A series of vinyl chloride, acrylic resin, meccrylic acid and styrene etc. refers to alcohol copolymers. Also, the word saran is generally used to refer to such chlorinated The scale includes not only vinylidene polymers but also polyvinylidene chloride. Saran's Its properties include that it is resistant to chemical changes due to ordinary acids and alkalis, and that it is resistant to water. In addition, it has excellent sturdiness and durability, allows a very small amount of air to pass through, and is For example, it can be purchased in the form of a sheet or film for forming containers. Also, d A family of chilled vinyl alcohol polymers or copolymers, product details: Co-extrusion or laminated sheet sold under the name A L J and films have high barrier properties that can be used in the containers of the present invention, so they are especially It's an interesting material. Also, a group of products commercially available under the trade name "5urlyn" Ionomeric resins are easy to thermoform. So it's practical. Other synthetic polymers can also be used depending on strength and protection needs. Ru. Such materials include styrene acrylonitrile (SAN).
