A packaging system includes a container (34) within which are disposed first detonator devices (10) having reactive coils (16), e.g., coils of shock tube leads, and second detonator devices (20) having inert coils (26), e.g., coils of insulated electric leg wires. The inert coils (26) are interposed between the reactive coils (16) and are approximately co-extensive with the reactive coils (16), so that the inert coils (26) form a barrier to propagation of an accidental initiation from one reactive coil (16) to another. Reactive coils (16) and inert coils (26) are fastened to each other to form mixed coil pairs (30) which are nested to interpose a pair of the inert coils (26) between at least some of the reactive coils (16). A method of packing the first and second detonator devices calls for placing them in a container (34) in the described arrangement.

To provide a toilet paper roll package that can be easily unsealed and that makes it possible to take out toilet paper rolls.

The toilet paper rolls are arranged in two rows with the peripheral surfaces abutting between the upper sealing portion and the lower sealing portion in gusset packaging, the upper sealing portion and the lower sealing portion are located at a position facing the peripheral surfaces of the toilet paper rolls, in the surface of the exterior film facing the end surface of the toilet paper roll, an unsealing portion formed by a perforation is formed, this unsealing portion includes an unsealing start portion with U-shaped or substantially V-shaped perforations arranged such that the upper sealing portion side is the top side, and a wide belt-shaped outlet forming portion formed by a pair of perforations that are continuous with both ends of the unsealing start portion and that extend toward the lower sealing portion, the unsealing start portion is closer to the upper sealing portion than the position adjacent to a pair of toilet paper rolls located closest to the upper sealing portion, and has an unsealing start auxiliary perforation extending from the U-shaped or substantially V-shaped top to the upper sealing side, and each perforation forming the outlet forming portion is located on the toilet paper roll group of each row arranged in two rows, and has a width of 0.5 to 1.2 times the toilet paper roll diameter.

A container is configured so that a bottom section has a ground contact section provided to the outer periphery of a body section, and a raised bottom section provided inside the ground contact section and deformed in accordance with a change in inner pressure; the raised bottom section is provided with an upper surface section provided at the center, and a connection section which connects the upper surface section and the ground contact section; the connection section is formed so that, when the inner pressure is normal pressure, the upper surface section-side end of the connection section is positioned closer to a neck section than the ground contact section-side end of the connection section; and at least the connection section of the bottom section is provided with a reinforcement section which extends in the radial direction of the bottom section and reinforces the bottom section.

A bottom section has a ground contact section which is provided at the outer periphery of a body section, and a raised bottom section which is provided inside the ground contact section. The raised bottom section is provided with a recessed section provided at the center, and a connection section which connects the recessed section and the ground contact section. The recessed section side end of the connection section is configured to be located closer to the neck side than the ground contact section side end when inner pressure is at ambient pressure.

A synthetic resin bottle, which has a pressure reduction absorbing performance and which exhibits a cylindrical shape in which the appearance of the body section to which the label is attached is similar to a perfect circle, is provided. A synthetic resin bottle 1 having cylindrical body section 3 has four pressure reduction absorbing panels 8 arranged at equal intervals in body section 3, and column portions 9 each having an arc-shaped wall surface 9a arranged between pressure reduction absorbing panels 8. Arc-shaped wall surface 9a of column portion 9 in a cross section of body section 3 constitutes a part of a virtual single true circle 10. Total circumferential length of arc-shaped wall surfaces 9a of column portions 9 is 55% to 75% of entire circumferential length of true circle 10.

Method for processing hot-filled plastic containers are provided. In some embodiments, the method may include hot-filling a plastic container, sealing the container, and conveying the sealed container, each with an inner annular wall and a push-up portion in a first position. In some embodiments, the method may further include creating a vacuum pressure in the hot-filled and sealed container and repositioning the push-up portion from the first position to a second position under a mechanical force.

A viscous liquid vessel system for presenting a gift is described herein. In some embodiments, the viscous liquid vessel system comprises a vessel containing a viscous liquid in which a gift is disposed. The vessel comprises a lid for enclosing the viscous liquid and the gift. The viscous liquid vessel system may be presented to a gift recipient and the gift recipient may remove the gift from the vessel and the viscous liquid creating a heightened emotion upon receipt and extraction of the gift.
