Description

Vacuum container

This creation relates to a vacuum container, especially one that achieves good sealing and solidity of the container. Determine the amount of material discharged and reduce the structure of the residual can.

According to the current society, due to frequent communication and environmental relations, people gradually pay attention to the maintenance of skin and color. Most of them will cleanse their skin or refine their skin with makeup or cleansing products such as makeup remover, facial cleanser, lipstick, skin care products and cosmetics. Better, these make-up removers, cosmetics, maintenance products, etc., are usually stored in bottles and cans.

The conventional packaging tank structure comprises a container body recessed with an accommodating space, the bottom of the container body has a through hole, and the accommodating space is covered by a joint member, and the joint member is provided with a first valve member. A piston is disposed in the space, and a pressing cover is further disposed on the connecting member. A sealing chamber is formed between the coupling member and the pressing cover, and the pressing cover is provided with a pressing portion and a second valve member. The department is flexible. When in use, the user presses down the pressing portion of the pressing cover, and a makeup in the chamber is squeezed out of the second valve member of the pressing cover, and when the user releases the pressing portion of the pressing cover, the pressing portion When the pressure is restored to the original state, the pressure in the chamber is small, and the makeup in the accommodating space is squeezed out of the second valve member to enter the chamber, so that the pressure in the accommodating space is small, and the through hole is arranged. The piston can be moved upward to balance the pressure of the accommodating space.

However, the conventional packaging can structure is a manual pressing of the pressing portion of the pressing cover by the user. According to the different force of the pressing force of the user, the amount of the cosmetic material is different, the excessive extrusion causes waste, and the extrusion is too small. It is also necessary to press again, and each time the conventional packaging can structure is used, the user needs to manually press the pressure to squeeze out the makeup, which causes inconvenience in use. Moreover, in order to maintain the airtightness and prevent the user from directly using the finger to take the makeup material in the accommodating space to cause contamination and deterioration of the makeup material, the pressing cover and the joint member are respectively provided with the first Two valve members to maintain the airtightness of the accommodating space However, it is also impossible to open the pressing cover and the coupling member to cause a large amount of makeup in the accommodating space to be left, thereby causing waste.

Forcing the contents 2 in the third chamber 122 to the second mounting hole 152, and then the contents flow into the flow path 193 of the connecting member 19, and the only passage of the third chamber 122 to the outside is the The second through holes 1633 of the second mounting groove 163, so that the contents 2 in the flow path 193 are pushed toward the second through holes 1633, and because the second valve member 17 is supported by the second support valve seat The recess 1712 of the 171 catches the second base 1631 of the second mounting groove 163, so that the contact surface 1732 of the second valve piece 173 of the second valve member 17 is pushed by the content 2 and the second mounting groove The second base 1631 of the 163 is separated and opened to the outside direction, and the contents 2 in the flow path 193 are outwardly passed through the second through holes 1633. After the third chamber 122 is balanced with the outside pressure, the second contact surface 1732 of the second valve piece 173 is returned to be attached to the second base 1631.

Referring to FIG. 6(c), the upper cover 16 is rotated again, and the second valley portions 1641 of the pressing ring 164 are again displaced to the first peak portions 1511 of the pressure receiving portion 151. The first peak portion 1511 is restored to the original shape, so that the pressure in the third chamber 122 is reduced. At this time, the pressure of the first chamber 1141 is greater than the third chamber 122, and the first chamber 1141 leads to the first portion. The only passage of the three chambers 122 is the first perforations 1213 of the first mounting groove 121, so that the contents of the first chamber 1141 will be pushed toward the first perforations 1213, and due to the first valve The first contact surface 1332 of the first valve piece 13 of the first valve member 13 receives the content of the first contact surface 1332 of the first valve member 13 by the first groove 1312 of the first support valve seat 131. After the pushing of the object 2 is separated from the first base 1211 of the first mounting slot 121, the third chamber 122 is opened, and the content 2 in the first chamber 1141 is supplemented to the first through hole 1213. The third chamber 122 reduces the pressure in the first chamber 1141, and the pressure of the second chamber 1142 is greater than the first chamber 1141, so the piston 14 is forced to the first chamber A chamber 1141 is raised in the upward direction until the pressure in the first and second chambers 1141, 1142 is balanced, and the first contact surface 1332 of the first valve piece 133 is restored to be attached to the first base 1211, and the piston is attached. 14 stop rising activities.

Therefore, through the design of the vacuum container 1 of the present invention, the vacuum container 1 can be effectively sealed to avoid the effect of the contents 2 contacting the air. In addition, by the structural design of the second peak portions 1642 of the pressure ring 164 of the present invention, the amount of the contents 2 extruded by the user each time the upper cover 16 is rotated is the same to achieve the effect of avoiding waste. In addition, the first valley portion 1511 and the first peak portion 1512 of the pressure receiving portion 151 having the elastic pressure receiving portion 151 are spaced apart from each other, and the second portion of the pressing ring 164 of the upper cover 16 The design of the valley portion 1641 and the second peak portions 1642 are spaced apart from each other, and the container body 11 and the upper cover 16 are coupled to each other through the first and second engaging portions 115 and 165, and the upper cover 16 is rotated. The axial heights of the container body 11 and the upper cover 16 are constant, so that the second peaks 1642 can be spaced apart. The displacement distance of the second valley portion 1641 continuously presses the first peak portions 1512, thereby achieving a labor-saving effect of allowing the user to squeeze the contents 2 without pressing with a finger.
