Description

Pattern description

The subject of the utility model is a flat container with a cap intended for use as a packaging for care products, especially creams.

The known containers have different shapes, with their upper part passing into a neck with a thread. One of the basic shapes is a flat cylinder-shaped body with a flat or concave bottom. The upper part of the cylinder passes into a neck provided with a three-threaded thread. The upper edge of the neck ends with a sealing lip. The lower part of the cylinder passes in a gentle curve into the bottom, the rim of which is a ring. A nut is a flat body shaped to fit the neck of a threaded cylinder. The upper part of the nut passes in a gentle arc into the bottom ending with a rim. The rim diameter corresponds to the inner diameter of the bottom ring. Inside, the cap has a thread that fits the thread of the container.

The purpose of the utility model is to develop a flat container and cap that will be easier to handle during production and use. According to the utility model, a flat container with a cap has the shape of a cylinder. The upper surface of the container sidewall extends into a neck provided with a four-threaded thread. The distance between adjacent threads in the axial section is 25-30% of the height of the neck of the container. The tilt angle of the upper edge of the thread of the container is at least 5 °. Preferably, the upper edge of the thread of the container has a slope angle of 5 °. The distance between the start and end of the next thread turn is at least 4.8 mm. Preferably, the distance between the start and end of the next thread turn is 4.8 mm. The upper edge of the neck ends with a sealing lip. The lower part of the cylinder passes in a gentle curve into the bottom, the rim of which is a ring. A nut is a flat body which has a shape corresponding to the neck of the cylinder provided with a thread. The upper part of the nut passes in a gentle arc into the bottom ending with a rim. The rim diameter corresponds to the inner diameter of the bottom ring. Inside, the cap has a thread corresponding to the thread of the container. The angle of the lower edge of the thread of the nut is at least 5 °. Preferably, the slope angle of the lower edge of the thread of the nut is 5 °.

The use of a four-hole thread on the neck of the container makes it easier to close and open the cap. The container is more airtight and thus prevents the cap from spontaneous opening caused by the forces acting during transport. The distance between adjacent coils in the axial section, constituting 25-30% of the height of the neck of the container, causes the perfect cooperation of the threads of the container with the cap. The threads of the container fit perfectly between the threads of the cap. This ensures parallelism in the first closing step which is pressing the cap onto the container after filling the container. The use of a minimum angle of 5 °, the same for the upper edge of the container thread and the lower edge of the cap thread, places the cap parallel to the container over a certain width. A distance of at least 4.8 mm between the start and end of the successive thread turn provides two thread turns virtually around the circumference. As a result, in the first closing stage, when the cap is pressed onto the container, it jumps around the entire circumference by a constant value.

The object of the utility model is shown in the embodiment in the drawing, in which fig. 1 shows the container with a cap in a front view, fig. 2 - a cap in a longitudinal section, fig. 3 - a container in a longitudinal section, fig. 4 - a container with a cap in longitudinal section, and Fig. 5 is a container with a cap in top view.

Example A flat container 1 with a cap 2 has the shape of a cylinder. The upper surface of the side wall of the container 1 passes into a neck 3 provided with a four-way thread 4. The axial distance 5 between adjacent threads 6 of thread 4 is 28% of the height of the neck 3 of container 1. The angle of inclination of the upper edge 7 of thread 6 of thread 4 of container 1 is 5 ° . The distance 8 between the start and the end of the next turn 6 of thread 4 is 4.8 mm. The upper edge 9 of the neck 3 ends with a sealing lip 10. The lower part 11 of the container cylinder 1 passes in a gentle arc into the bottom 12, the rim of which is a ring 13. The cap 2 is a flat body, which has a shape corresponding to the neck 3 of the container 1 provided with threads 4. The upper part 14 of the cap 2 passes in a gentle curve to the bottom ending rim 15. The diameter of rim 15 corresponds to the inner diameter of the bottom ring 13. Inside, the cap 2 has a thread corresponding to the thread 4 of the container 1. The angle of inclination of the lower edge of the thread 6 of the thread 16 of the cap 2 is 5 °.
