Description

  The present invention relates to a plastic bottle and a plastic beverage container that can be kept warm and cool.

Currently, there are cold bags, cold covers, and cold containers that contain plastic bottles, but none of them can be kept warm or cold. Although PET bottles are very light as containers and are convenient to carry, they are recyclable containers, but unfortunately the contents of containers are easy to cool and warm. There are thermostainers made of glass, stainless steel, and titanium as heat insulation and cold insulation containers, but they are heavy and bulky and tend to be avoided.

  Insulating and cooling effects are inferior to those of magic bottles made of glass, stainless steel, or titanium. However, plastic bottles and plastic beverages that can be kept warm and cool in order to keep warm, cool and lightweight PET bottles, and convenience. The purpose is to provide a container.

  In order to achieve the above object, the heat- and cold-preserving PET bottle and plastic beverage container according to claim 1 have a double structure of the inside and the outside. From inside to outside or from outside to inside, ribs, thin plates, or protrusions are provided to reinforce the inside and outside, and the hollow part between the inside and outside is vacuumed In the state, or in the medium, low vacuum state, or normal state with air, there is a difference in effect, but it can be kept warm or cold. Furthermore, in order to increase the heat insulation and cold insulation effect, light, light or heat is shielded or reflected on the inner surface of the double structure, the outer surface of the outer surface, or the inner surface of the outer surface (for example, aluminum is vacuum-deposited) It is characterized in that it is attached or coated.

  Insulating and reinforcing PET bottles and beverage containers that can be kept warm and cool according to claim 2 by providing a heat insulating material between the inside and outside without providing ribs, thin plates, or protrusions. It is characterized by being a plastic bottle or a plastic beverage container that can be kept warm and cool according to claim 1.

  The plastic bottles and plastic beverage containers that can be kept warm and cool according to claim 3 do not have a double structure, and make a concave portion that is as large but not deep as possible on the side of a normal plastic bottle or plastic beverage container. Reinforcing ribs on the entire side or the entire side of the container except the neck of the container, or those that shield or reflect light or heat (for example, aluminum-deposited film or aluminum foil) It is characterized by being a heat-retaining, cold-retaining plastic bottle, or a plastic beverage container.

  A heat- and cold-retainable plastic bottle or plastic beverage container according to claim 4 is a material that shields or reflects light, light, or heat from the entire side surface or the entire side surface except the container neck (for example, aluminum A plastic bottle or a plastic beverage container that can be kept warm and cool, according to claim 3, wherein a heat-insulating material is entirely sandwiched between the film and the aluminum foil or the like obtained by vacuum evaporation.

  The plastic bottles and plastic beverage containers that can be kept warm and cool according to claim 5 do not have a double structure, and make a concave portion that is as large but not deep as possible on the side of a normal plastic bottle or plastic beverage container. Reinforcing ribs in some places in the recess, the entire side or the entire side except the container neck is surrounded by a heat-insulating material, and the outermost part is covered with a heat shrink film etc. It is a container.

  Although it has a double structure like a thermos, it is made of plastic, so it weighs about 1/3 to 1/4 of a stainless steel thermos and is convenient to carry. Removed the disadvantage of the thermos that had been avoided because it was heavy.

  Because it is in the shape of a plastic bottle, there is no need to transfer the beverage to a cup.

  By inserting ribs or the like into the double-structured hollow portion, the strength was remarkably increased, and defects in the plastic container were removed. In addition, the reinforcement of the ribs or the like allows the hollow portion to be kept hollow even when the hollow portion is in a vacuum state, or in a middle or low vacuum state.

Since the hollow portion can be in a vacuum state, or in a medium or low vacuum state, the outside air and the beverage in the container can be shut off, and heat insulation and cold insulation can be efficiently performed.

  The heat insulation and cooling effect can be further enhanced by attaching or coating light, light or heat shielding or reflection on the inner surface of the double structure, or the outer surface of the outer surface or the inner surface of the outer surface. .

  By devising the five types of double-structure containers shown in FIGS. 1, 2, 3, 4, and 5, various manufacturing methods are possible.

  6, 9, and 12 are simplified heat and cold containers. Although the heat insulation and cold insulation effects are inferior, it does not take a double structure, so there is an advantage that it can be produced by conventional production methods and techniques.

  Even if air enters the recess covered with the film, the beverage in the container has this hollow part, so it does not touch the outside air directly, and the outside air and the inside air temperature are temporarily stopped in the hollow part. Although not as heavy as a heavy structure, hot beverages can be kept hot and cold beverages can be kept cold. When tested in a room with a temperature of 32 ° C, an ordinary 8 ° C plastic bottle drink from the refrigerator would be 22 ° C in 40 minutes, but a 40-minute bottled plastic bottle covered with insulation was passed. Even at 18 ° C, there was a difference of 5 ° C.

  If the surface is covered with a film that has been vacuum-deposited with aluminum, or a single heat-shrink film that has been vacuum-deposited with aluminum on the back side, the product name and contents are marked on the front side. Is shielded and reflected to further increase the heat-retaining and cold-retaining effects of the beverage in the container.

  When making the hollow part of the concave part into a low vacuum, if the upper and lower parts of the container are uneven, or if a spiral shape is applied or an adhesive is applied, the outermost heat shrink film etc. will adhere to the container, The airtightness of the hollow portion is enhanced, and the heat retaining property and the cold retaining property are further improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS A plastic bottle and a plastic beverage container that can be kept warm and cool according to the present invention will be described below with reference to the accompanying drawings. In FIG. 1, the code | symbol 11 is a longitudinal cross-sectional view of the plastic bottle and plastic beverage container which can be heat-retained and cooled. The container has a double structure of inside and outside, and ribbed, thin plate, or protrusions are provided from the inside to the outside or from the outside to the inside. Reinforcement is peeled off. Due to this reinforcement, the hollow portion between the inner side and the outer side can be kept hollow even in a vacuum state, a middle, low vacuum state, or a normal state containing air. In order to increase the heat retaining and cooling effect, light, light or heat shielding material, or reflective material is attached or coated on the inner outer surface of the double structure, the outer outer surface, or the outer inner surface. In this case, you may attach the heat shrink film which expresses a brand name and contents to the outside of the film etc. which vacuum-deposited aluminum new iron, that is, the outermost part, and the text which expresses a brand name and contents turns to the front side, and the back side Alternatively, a single heat shrink film obtained by vacuum-depositing aluminum may be used.

  In the embodiment shown in FIG. 3, the neck of the container does not have a double structure, and the bottom from the neck has a double structure.

  The embodiment shown in FIG. 4 does not have a double structure at the bottom of the container, but has a double structure other than the bottom.

  The embodiment shown in FIG. 5 is a double-structure container in which a heat insulating material is inserted between the inner side and the outer side without providing ribs, thin plates, or protrusions.

  The embodiment shown in FIG. 6 is a container in which the neck and the bottom are not made into a double structure, but only the side part is made into a double structure.

  In FIG. 7, reference numeral 6 indicating the whole is a vertical cross-sectional view of a plastic bottle or beverage container that is not double-structured and can be kept warm and kept cool. The embodiment shown in FIG. 7 does not take a double structure, but has a concave portion that is as large and not deep as possible on the side of a normal plastic bottle or plastic beverage container, and reinforcing ribs are inserted in the concave portion in some places. . The outermost heat-shrink film or aluminum vacuum-deposited film covers the upper part of the concave part to create a hollow part, but this rib is for the concave part to fully function as a hollow part, that is, these The ribs are not necessary if the film is not in contact with the bottom of the recess, so that the film does not contact the bottom of the recess. Rather than making it, it is better to reinforce it by putting ribs in large recesses. Install light, light or heat shielding material or reflective material (for example, vacuum-deposited aluminum film) on the entire side surface or the entire side surface except the container neck to shield light and heat from outside. Or reflected.

  Also, even if this hollow part is not vacuum and the air is in the beverage, the beverage in the container has this hollow part, so it does not touch the outside air directly, and the outside air and the inside temperature are temporarily stopped in the hollow part. Hot and cold beverages can be kept cold. You may attach a heat-shrink film, etc., on the outside of the film, such as vacuum-deposited aluminum, that is, on the outermost side. A single heat shrink film or the like obtained by vacuum deposition may be used.

  If the hollow portion is set to a medium or low vacuum state, the beverage temperature in the container is less likely to be transmitted to the outside.

FIG. 8 does not have a double structure, but a concave portion that is as large and not deep as possible is formed on the side of a normal plastic bottle or plastic beverage container, and reinforcing ribs are inserted in the concave portion in some places.
The entire side surface or the entire side surface excluding the container neck is surrounded by a heat-insulating material and covered with a heat shrink film. The outermost heat shrink film etc. and the heat insulating material cover the upper part of the concave part to make a hollow part, but this rib is for the concave part to fully function as a hollow part, that is, a heat shrink film etc. Since the heat insulating material is intended to prevent contact with the bottom of the recess, ribs are unnecessary if the size is such that the film and the heat insulating material do not contact the bottom of the recess. Considering that it is better to reinforce with large ribs than to make many depressions. Ordinary air may be contained in the hollow portion, and the heat retaining property and the cold retaining property are still good if it is a medium or low vacuum.

  In FIG. 8, aluminum may be directly vacuum-deposited on the back surface of the heat insulating material and sandwiched between the outermost heat-shrinkable films, or aluminum may be vacuum-deposited on the back surface of the heat-shrinkable film.

  In FIG. 10, the upper and lower portions of the container are made uneven or spiral, and the outermost heat shrink film or the like is in close contact with the container to improve the airtightness of the hollow portion. Furthermore, in order to improve airtightness, you may apply | coat an adhesive to the film side or the convex-concave part of a container, or a helical part.
