Description

Detailed description of the container invention

The present invention relates to opening and closing of a cap of a plastic bottle and is provided on the bottom surface of the plastic bottle. In particular, the cap of the plastic bottle can be easily opened. It also relates to the processing and storage of bulky empty plastic bottles.

Plastic bottles are an indispensable product for people living. In addition, PET bottles are convenient to carry, are not easily broken, and have the advantages of being hard to leak liquid, so they are often carried during disasters, exercises, and outdoor activities. However, it is necessary to open the PET bottle cap by rotating it.If the user is sick or an elderly child, there is a limit to the force to rotate the cap. In addition, there is a need for a resolution on how to handle and store empty PET bottles that are bulky in hospital rooms and storage locations.

Problems to be solved by the invention

In the conventional opening / closing method, since an opening / closing device is used, inconvenience is required. In addition, it prevents scattering of empty plastic bottles, cleans up afterwards, storage functions that save space, and vertical and horizontal connection functions.

In order to achieve the above-mentioned purpose, a plastic bottle body is utilized by using the concave and convex space into which the cap, the ring and the flange 7 enter, the function of opening the plastic bottle and the cap, and the joining of the main body and the cap. The arrangement and connection of each other simplifies the management and storage of PET bottles. In addition, fluid water containing drinking water, or edible oil, soy sauce, fruit juice, liquid containing sauce, or powder containing rice, wheat, granule, sugar, salt, etc. A container bottom surface 8 provided with a space for accommodating the cap 1 and the flange 7 of the drinking mouth on the outer side surface 9 of the inner bottom 8 of the plastic bottle container main body, the irregularities for loosening the cap, the ring and the flange groove, and the cap 1 attached thereto. The cap surface of the container, the flange uneven surface, the flange, and the groove are bonded, and a plurality of containers can be connected.

Means for solving the problem

In order to achieve the above object, the first aspect of the present invention is a first step in which the cap bottle, the ring, and the flange 7 are provided in an uneven space in the inner bottom 8 of the plastic bottle body.

[Claim 2] The function of opening the cap 1 by twisting the main body containers to the left and right without bonding and bonding the concave and convex container, the cap 1, the ring, and the flange 7 surface of the main body container bottom 8 It becomes. Second step.

[Claim 3] The plastic bottles are connected to each other by using the bonding between the main body and the cap. By using the concave / convex surface of the main body container bottom 8 and the concave / convex surface of the cap 1, the ring and the flange 7, the cap 1 can be opened and a plurality of plastic bottles can be connected. Also, emergency food seal filled with grains of drinking water, edible oil, soy sauce, alcoholic beverages, vinegar, soup stock, sauce, mayonnaise, chap or rice, wheat, soybean flour, sesame seeds, rice cake, matcha tea, kelp, spices, etc. Third step to become a storage container.

Injection molding is a processing method such as polyethylene or plastic. The case of a thermoplastic resin is typical, and a softening temperature and heated plastic are pressed into a mold by applying an injection pressure (10 to 3000 kgf / c), and the mold is filled and molded. In the conventional manufacturing process, when screwing the main body to the bottom of the plastic bottle, even if it is brought into contact with the inner wall of the bottom of the plastic bottle, the outer cylinder main body is in contact with the inner wall of the plastic bottle mouth. It can be prevented from being deformed or deformed.

In the container structure containing drinking water, fluid water, liquid, and granule powder according to claim 1, the container with a cap attached to the neck of the bottle-shaped container is a container body bottom in which a cap and a flange are housed in the body container bottom. In addition, a concave / convex ring, a lid portion and a flange for closing the outside of the cap of the container body are provided, and the concave / convex ring and flange groove in the space at the bottom of the container main body have a vertical concave / convex portion, and the inner peripheral edge portion is capped. A concave / convex ring, a flange groove, and a vertical concave / convex surface joint are formed in a concave portion between the flange at the neck of the container bottle-like container and the bottom of the container main body.

In the container structure according to claim 2, the bottom of the container includes a side extending downward, a concavo-convex portion forming a bottom connected to the lower end of the side, and a concavo-convex object or a concave-convex ring-shaped flange groove, A container bottle-shaped container with a cap is connected and connected to a space formed below the side.

In the connection container structure according to claim 3, when the connection container is mounted on the container with a cap in a predetermined state, the highest position of the connection container and the top of the container with the cap have substantially the same height and diameter. It is configured to be.

In the connected container structure according to claim 4, the maximum dimension in the horizontal direction parallel to the side plate of the connected container is substantially equal to or smaller than the outer diameter of the container body in the container with a cap. Yes.

In the connection container structure according to claim 4, the neck insertion hole has an elliptical shape, the long diameter is the shortest dimension through which the lid of the cap-equipped container can pass, and the short diameter is less than the maximum outer diameter of the lid. It is formed smaller than the lid in the range of 0.05 to 0.01 mm.

A conventional plastic bottle container has a cap lid made of different materials used on a rectangular container and a cylindrical container with a narrow upper part. The shape of the lid 1 is substantially the same, and the concave / convex surface of the outer ring 10 having the outer surface of the lid 1, the outer ring ring irregularity 10 and the cap 1 has six points on the inside of the container bottom irregular outer ring 10. By forming the 6-21 square-sided irregular shape of the same size, the concave / convex shape of the cap outer ring 1 on the outside of the container bottom serves to join the two main bodies and loosen or connect the torsional lid to the left and right. do.

Further, the empty plastic bottle container 2 is cap 1 and a plurality of plastic bottle containers obtained by joining and joining the outer ring 10 and the cap outer ring 1 at the bottom of the container are joined in a longitudinal direction and a lateral direction to prevent scattering of the container, Make it easy to carry and store. Moreover, the outer cylinder part main body of an outer cylinder part is comprised with the material whose bending elastic modulus (JISK6921-2) is 1200 Mpa or less and whose surface hardness (JISK7202 (R scale)) is 85 or more. . In the case of a thermosetting resin, it is first heated to around 50 ° C. to give fluidity, and then filled into a high-temperature mold (about 150 ° C.) and cured (solidified).

Effect of the invention

By connecting an empty container that does not require force to loosen the cap lid of a plastic bottle container containing drinking water, liquid water, liquid, granule, and without using an instrument, Can simplify the time and effort of spreading and carrying and storage management of containers, emergency drinking water, edible oil, chili oil, soy sauce, liquor, vinegar, soup stock, sauce, mayonnaise, ketchup or rice, wheat, soy flour Storage of containers filled with any one of the powder and sealed storage storage containers for ingredients containing rice, wheat, soybeans, sesame seeds, rice cake, matcha, kelp, spices, sugar, various seasonings, etc. It becomes a plastic bottle container with many fields of use.
