Specific embodiment

Below in conjunction with the accompanying drawings and embodiment is described in detail to the utility model.

Refering to Fig. 2,3, one embodiment of the utility model container is sleeved on the appearance comprising a vessel 2, The check (non-return) valve 4 that discharge head 3, on device body 2 is socketed with the discharge head 3, and one removable installed in the container Lid 5 on body 2.The vessel 2 is adapted to contain the content of such as fluid, but when in use not with foregoing citing It is limited.The vessel 2 has a wall 21 that can be deformed, and one by containing that the wall 21 is defined Space 22, the wall 21 has the discharging portion 211 that caliber reduces, and this contains space 22 with one to should discharging portion 211 discharging opening 221.The discharge head 3 is mounted at the discharging portion 211 of the vessel 2, and with one around ring wall 31, and a tapping channel 32 defined around ring wall 31 by this, should around ring wall 31 have one can frame lean against this The frame relying part 311, one of the upper limb of discharging portion 211 of vessel 2 down stretches into the vessel 2 by this relying part 311 Fit portion 312 in the discharging portion 211, and a shrinkage part 313 up extended by this relying part 311, in the fit portion 312 have a prominent ring 314 of clip protruded toward radial outer end.

The check (non-return) valve 4 is to be made of plastics, and with outside of fit portion 312 for being sleeved on the discharge head 3 The valve wall 42 of the neighbouring discharging opening 221 of the collar 41, and several are connected to the elasticity between the collar 41 and the valve wall 42 Latticing 43.The collar 41 has a ring wall 411, and the fit that the fit portion 312 for allowing the discharge head 3 closely penetrates Hole 412, the ring wall 411 has a clamping groove 413 for the prominent engaging of ring 314 of the clip of the confession discharge head 3, the clamping groove 413 And the position that the prominent ring 314 of the clip is set can be exchanged, the valve wall 42 is platy structure, and can be because of the elastic latticing 43 Elasticity is shored, and the discharging opening 221 toward the vessel 2 is pressed against, and closes the discharging opening 221.The elastic latticing 43 is It is spiral helicine to be connected between the collar 41 and the valve wall 42.

The lid 5 has a basal wall 51, and is combined harmoniously by 52, set of an assembled wall that the basal wall 51 down extends 53rd, a stick harness 54.The assembled wall 52 is removable combination on the discharging portion 211 of the vessel 2.In this implementation There is example, the inner peripheral surface that the outer peripheral face of the discharging portion 211 has an external screw thread, the assembled wall 52 one to coordinate with the external screw thread Internal thread, by the lid 5 relative to the spiral shell of vessel 2 turn, can be by the removable combination of lid 5 in the container sheet On body 2.But in manufacture, the discharging portion 211 and the assembled wall 52 can also be by the removable combinations of other structures, such as By being combined in the prior art of flush structure or shrink-fit structure etc..As long as that is, the present embodiment lid 5 can It is removable on the vessel 2, it is possible to reach expected creation purpose.And the set combine harmoniously 53 and the stick harness 54 be Be engaged with the discharge head 3, and can frame lean against the upper limb of shrinkage part 313 of the discharge head 3, while blocking the tapping channel 32.

Refering to Fig. 4,5, when in use, the collar 41 of the check (non-return) valve 4 is to be sleeved on the discharge head 3 for the present embodiment container At the fit portion 312 of ring wall 31 then the assembly should be together sleeved on the discharging portion of the vessel 2 In 211.After being arranged, shored by the elastic latticing 43, the valve wall 42 of the check (non-return) valve 4 down acts against the vessel Near 2 discharging opening 221, and the discharging opening 221 is closed, and the lid 5 is by the assembled wall 52 and the vessel 2 Removable combination.That is, when the present embodiment container position is in a non-return position shown in Fig. 4, the check (non-return) valve 4 The valve wall 42 because the effect of the elastic latticing 43, and can have the discharging opening 221 of the closing of the elasticity vessel 2.

At this time, the content in the tapping channel 32 has been flowed to, it is impossible to be back to this and contain in space 22, it is outside Dust and air also cannot be back to this and contain space 22 via the tapping channel 32, therefore the present embodiment check (non-return) valve 4 can be kept away Exempt to have flowed out the air return of content that this contains space 22 and outside, to improve the storage quality of content.

When user will extrude and be stored in this of the vessel 2 and contain the content in space 22, this is first turned on Lid 5, and the wall 21 of the vessel 2 is extruded, the pressure of extruding can just promote the valve wall 42 of the check (non-return) valve 4 to overcome The elastic force of the elastic latticing 43 leaves the discharging opening 221, this when, the container will be transformed into Fig. 5 by the non-return position of Fig. 4 Shown one uses position.After the pressure releases of the vessel 2 are extruded, acted on by the elastic latticing 43, should The valve wall 42 of check (non-return) valve 4 can be moved down again, and close the discharging opening 221 of the vessel 2.
